                             principal on the Class A, Class M-1, Class M-2,
                             and Class B-1 certificates. The applicable class

                             percentage of a formula amount dictated by the
                             principal due, whether or not collected, and
                             other collections on the manufactured housing
                             contracts for that remittance date will be paid:
                                    
                                 ^to the Class A-1 certificates until retired,
                                  then     
                                    
                                 ^to the Class A-2 certificates until retired,
                                  then     
                                    
                                 ^to the Class A-3 certificates until retired,
                                  then     
                                    
                                 ^to the Class A-4 certificates until retired,
                                  then     
                                    
                                 ^to the Class A-5 certificates until retired,
                                  then     
                                    
                                 ^to the Class A-6 certificates until retired,
                                  then     
                                    
                                 ^to the Class A-7 certificates until retired,
                                  then     
                                    
                                 ^to the Class M-1 certificates, then     
                                    
                                 ^to the Class M-2 certificates, and then     
                                    
                                 ^to the Class B-1 certificates.     
                                
                             Before the remittance date in     , the
                             applicable class percentage for the Class M
                             certificates and the Class B certificates will
                             probably be zero. Thereafter, assuming
                             delinquencies, defaults and losses on the
                             manufactured housing contracts remain below
                             certain thresholds, the applicable class
                             percentage for each class will probably be
                             proportionate to its outstanding balance. See
                             "Description of the Certificates--Distributions"

                             calculation of principal payable on the
                             certificates.     
 
C. Class B-2 Interest......     
                             After paying the amounts of interest and
                             principal due on the other certificates described
                             above, the trustee will then apply the remaining
                             amount available for distribution to pay interest
                             on the Class B-2 Certificates. See "Description
                             of the Certificates--Distributions" and "--Losses
                             on Liquidated Contracts."     
                                
D. Class B-2 Principal.....  After paying the amounts of interest and
                             principal due on the certificates described
                             above, the trustee will then apply the remaining
                             amount available for distribution to pay
                             principal due on the Class B-2 certificates. In
                             general, principal will not be payable on the
                             Class B-2 certificates until the

                             Class B-1 certificates have been retired. After
                             that has occurred, the Class B-2 certificates
                             will be entitled to receive principal in an
                             amount equal to the Class B Percentage of the
                             Formula Principal Distribution Amount described
                             above. See "Description of the Certificates--
                             Distributions" and "--Losses on Liquidated
                             Contracts."     
 
Subordination of Class M-
 1, Class M-2, Class B,
 Class B-3I and Class C
 Certificates..............     
                             The Class M-1 certificates, Class M-2
                             certificates, Class B certificates, Class B-3I
                             certificates and Class C certificates will be
                             subordinated to the Class A certificates in
                             payment of both interest and principal. The
                             trustee will apply the amount available for
                             distribution on any remittance date to interest
                             and principal on the certificates in the order
                             listed in "Priority of Distributions" above. This
                             increases the possibility that the Class A
                             certificates would be paid in full but the other
                             classes of certificates would not. The Class B
                             certificates will be subordinated to the Class A
                             and Class M certificates in the same manner. The
                             Class B-3I and Class C certificates will be
                             subordinated to all the other certificates. See
                             "Description of the Certificates--Distributions"
                             for a more detailed description of the manner and
                             order of priority of distributions on the
                             certificates.     
                                       
                             In addition, if there are severe losses and
                             delinquencies on the manufactured housing
                             contracts, those losses will first be imposed on
                             the Class B-2 certificates, and then on the Class
                             B-1 certificates, and so on through classes of
                             increasing seniority. See "Description of
                             Certificates--Losses on Liquidated Contracts" for
                             a more detailed description of the allocation of
                             losses on the contracts.     
 
Class B-2 Limited               
 Guarantee.................  Green Tree will guarantee payment of interest and
                             principal on the Class B-2 certificates. See
                             "Description of the Certificates--Limited
                             Guarantee of Green Tree" for a complete
                             description of Green Tree's obligation under the
                             Class B-2 limited guarantee.

Capitalized Interest            
 Account ..................  A capitalized interest account will fund interest
                             payments on the certificates on the remittance
                             dates in     and     1999 if collections on the
                             manufactured housing contracts are insufficient.
                                 
Repurchase Option..........     
                             After the aggregate principal balance of the
                             contracts is less than 10% of their aggregate
                             principal balance at the time they were
                             transferred to the trust, Green Tree will have
                             the option to purchase all of the outstanding
                             manufactured housing contracts. See "Description
                             of the Certificates--Repurchase Option" in this
                             prospectus supplement and in the prospectus for a
                             more detailed description of the terms of this
                             repurchase option.     
                             
    
   
The Contract Pool.....       The trust will own a pool of fixed rate
                             manufactured housing installment sale contracts
                             and installment loan agreements. This prospectus
                             supplement provides information regarding a
                             portion of the contracts, representing about  %
                             of the total pool, which we refer to as the
                             "initial contracts." Green Tree will transfer
                             another portion of the contracts, which we refer
                             to as the "additional contracts," to the trust on
                             the closing date. If the aggregate principal
                             balance of the initial contracts and the
                             additional contracts is less than the aggregate
                             original principal balance of the certificates,
                             we may transfer contracts representing that
                             difference to the trust no later than         .
                             This last group of contracts is referred to as
                             the "subsequent contracts." [/R]
                                                                               

    
                             
    
                                                   
Initial Contracts..... [/R]  With respect to the initial contracts, as of  ,
                             1999: [/R]

                                  states;

                             description of the initial contracts and the
                             permissible characteristics of the other
                             contracts that Green Tree will transfer to the
                             trust on the closing date or later.     
 
Pre-Funding Account........     
                             If the aggregate principal balance of the
                             contracts Green Tree transfers to the trust on
                             the closing date is less than the aggregate
                             original principal balance of the certificates,
                             the trustee will deposit the difference in the
                             pre-funding account, and those funds will be used
                             to purchase contracts from time to time until
                                   , 1999. If those funds are not completely
                             used by       , 1999, any remaining funds will be
                             distributed as principal on the Class A-1
                             certificates on the next remittance date.     
 
Tax Status.................     
                             In the opinion of Green Tree's counsel, for
                             federal income tax purposes the trust will
                             consist of two segregated asset pools--the
                             "Master REMIC" and the "Subsidiary REMIC"--and
                             each will be treated as a separate "real estate
                             mortgage investment conduit" as described in the
                             Internal Revenue Code. The Class A certificates,
                             the Class M certificates, the Class B
                             certificates and the Class B-3I certificates will
                             constitute "regular interests" in the Master
                             REMIC and generally will be treated as debt
                             instruments of the trust for federal income tax
                             purposes. The Class C certificates will
                             constitute "residual interests" in the Master
                             REMIC and the Subsidiary REMIC. As a holder of
                             certificates, you will be required to include as
                             income interest on your certificates, including
                             any original issue discount, under the accrual
                             method of accounting, even if you usually use the
                             cash method of accounting. See "Certain Federal

Money Market Eligibility...     
                             The Class A-1 certificates will have a final
                             maturity date of        , 2000. The Class A-1
                             certificates will be eligible securities for
                             purchase by money market funds under Rule 2a-7
                             under the Investment Company Act of 1940. A fund
                             should consult with its advisor regarding the
                             eligibility of the Class A-1 certificates under
                             Rule 2a-7 and the fund's investment policies and
                             objectives.     
 
ERISA Considerations.......     
                             Subject to the conditions described under "ERISA
                             Considerations," employee benefit plans that are
                             subject to the Employee Retirement Income
                             Security Act of 1974 may purchase the Class A
                             certificates. An employee benefit plan may not
                             purchase any other class of certificates, unless
                             it satisfies the conditions described under
                             "ERISA Considerations" in this prospectus
                             supplement and in the prospectus.     
 
Legal Investment                
 Considerations............  The Class A certificates and the Class M-1
                             certificates will not constitute "mortgage
                             related securities" for purposes of the Secondary
                             Mortgage Market Enhancement Act until the amount
                             in the pre-funding account is zero. Then, the
                             Class A certificates and Class M-1 certificates
                             will be "legal investments" for certain types of
                             institutional investors as provided in SMMEA. The
                             Class M-2 certificates and the Class B
                             certificates also will not constitute "mortgage
                             related securities" for purposes of SMMEA because
                             they will not be rated in one of the two highest
                             ratings by S&P and by Fitch. This means that many
                             institutions that have the legal authority to
                             invest in "mortgage related securities" may not
                             be legally authorized to invest in the
                             certificates. You should consult with your own
                             legal advisor to decide whether and how much you
                             may legally invest in the certificates.     
 
Ratings....................
                                
                             The certificates will not be issued and sold
                             unless S&P and Fitch have assigned the ratings
                             listed on page S-3, or better, to the
                             certificates.     
                                
                             The rating of each class of certificates by S&P
                             addresses the likelihood of timely receipt of
                             interest and ultimate receipt of principal. The

                             rating of each class of certificates by Fitch
                             addresses the likelihood of timely payment of
                             interest and ultimate payment of principal. A
                             security rating is not a recommendation to buy,
                             sell or hold securities and may be subject to
                             revision or withdrawal at any time by the
                             assigning rating agency. The ratings of the Class
                             B-2 certificates are based in part on an
                             assessment of Green Tree's ability to make
                             payments under the Class B-2 limited guarantee.
                                    
                             Although Green Tree has not requested a rating of
                             the certificates from any rating agencies other
                             than S&P and Fitch, other rating agencies may
                             rate the certificates. These ratings could be
                             higher or lower than the ratings S&P and Fitch
                             initially give to the certificates.

                                  RISK FACTORS
   
      You should consider the following risk factors in deciding whether to
purchase the certificates.     
          
Different classes of certificates have different risks of delinquencies and
defaults on the manufactured housing contracts. The more subordinate classes
face greater risks from delinquencies and defaults.     
   
      Delinquencies and defaults on the manufactured housing contracts will
result in a smaller amount of cash available for distribution on a remittance
date. Because the available cash is distributed in a specified priority, there
is a risk that certificates that are lower in that priority may not receive
some or even any of the amount due to them on that remittance date. In
addition, there is a risk that a high rate of defaults and losses on the
manufactured housing contracts could result in the outstanding principal
balance of the manufactured housing contracts being lower than the outstanding
principal balance of the certificates. A discrepancy like this would result in
a liquidation loss, which would be imposed first on the Class B-2 certificates
until their principal balance was reduced to zero, then on the Class B-1
certificates until their principal balance was reduced to zero, and so on in
increasing order of seniority.     
   
The more senior classes of certificates have limited protection from
delinquencies and defaults.     
   
      The only protection against delinquencies and liquidation losses for the
more senior classes of certificates is the subordination of the more
subordinate classes. For example, if there are high delinquencies or
liquidation losses on the contracts, the Class B-1 certificates would lose the
protection against losses afforded by the subordination of the Class B-2
certificates, Class B-3I certificates and Class C certificates, and investors
in the Class B-1 certificates might suffer a loss on their investment. Even
higher delinquencies or liquidation losses on the contracts would eliminate the
protection the Class M-2 certificates have from the subordination of the Class
B-1 certificates, and so on for the Class M-1 certificates and then the Class A
certificates. For more information, see "Description of the Certificates--
Subordination of Class M-1 Certificates, Class M-2 Certificates, Class B
Certificates, Class B-3I Certificates and Class C Certificates."     
          
The timing of distributions of principal is uncertain.     
   
      The Class M-1, Class M-2 and Class B certificates will not receive
distributions of principal until distribution tests are satisfied, and those
distributions of principal will stop if those tests are not met later. Those
tests depend on the rate of prepayments on the manufactured housing contracts
and on the level of delinquencies, defaults and losses of those contracts. We
cannot predict when the tests for distributions of principal on the Class M-1,
Class M-2 and Class B certificates will be satisfied, or when principal will be
paid on the Class M-1, Class M-2 or Class B certificates. For more information,
see "Yield and Prepayment Considerations" in this prospectus supplement and
"Maturity and Prepayment Considerations" in the prospectus.

Downturns in regional or local economic conditions historically have caused
increased delinquency, defaults and losses on manufactured housing contracts.
       
      An economic downturn in any region where a number of the obligors on the
contracts are located might cause higher delinquencies, defaults and losses on
the contracts. If delinquencies, defaults or losses on the contracts are higher
than expected, you could suffer a loss on your investment.     
   
A manufactured home generally depreciates over time.     
   
      The market value of a manufactured home may decline faster than the
outstanding principal balance of the loan for that home. If the value of the
manufactured homes securing the contracts declines faster than expected, then
defaults and losses on the contracts may rise. If the losses on the contracts
are not covered by the subordination of other classes of certificates, or by
another form of credit enhancement, you will bear all the risk of loss of
default by obligors and will need to look primarily to the value of the
manufactured home to recover the outstanding principal and unpaid interest on
the defaulted contract. For more complete information on Green Tree's loss
experience in manufactured housing contracts, see the section entitled "The
Trust Fund--The Contract Pools" in the prospectus.     
   
The certificates are not an obligation of Green Tree and they are not insured.
       
      Unless we specify otherwise in this prospectus supplement, the
certificates will not represent an interest in or obligation of Green Tree. The
certificates are not insured or guaranteed by the government, any underwriter
or its affiliates, the servicer or any other party.     
   
The certificates may have limited liquidity.     
   
      There is a risk that a secondary market will not develop for the
certificates of any series. There are also risks that if a secondary market
does develop:     
         
      .it may not provide you with liquidity of investment; or     
         
      .it may not continue for the term of any series of certificates.     
   
The contracts may be prepaid before their scheduled maturity.     
   
      There is a risk that the contracts may be prepaid in full or in part at
any time before their scheduled maturity due to various factors, such as:     
         
      .homeowner mobility,     
         
      .general and regional economic conditions,     
         
      .prevailing interest rates, and     
         
      .natural disasters.

     The prepayment experience on manufactured housing contracts varies
greatly and may affect the average life of the certificates. If a contract is
prepaid in full, the interest on the contract will accrue only to the date of
prepayment. If you purchase a certificate at a discount, then slower than
expected prepayments on the contracts will reduce the yield on your
certificate. If you purchase a certificate at a premium, then faster than
expected prepayments on the contract will reduce the yield on your
certificate. You must not assume that the contracts will prepay at any
particular rate, or at a constant rate. For more information on prepayment on
the contracts, see the section entitled "Yield and Prepayment Considerations"
in this prospectus supplement and "Maturity and Prepayment Considerations" in
the prospectus.     
   
Some contracts may not be enforceable.     
        
     The security interest in the manufactured home may not be perfected.     
   
     Every manufactured home contract will be secured by a security interest
in either (1) the manufactured home; or (2) if it is a land-and-home contract,
the mortgage or deed of trust on the real estate where the manufactured home
is permanently affixed. Several federal and state laws, including the Uniform
Commercial Code as adopted in each state, govern the perfection of security
interests in the manufactured homes and the enforcement of rights to realize
upon the value of the manufactured homes as collateral for the contracts. In
most states, certificate of title statutes, although generally not state real
estate laws, also govern the perfection of security interests and the
enforcement of these rights. The steps required to perfect a security interest
in a manufactured home vary from state to state. Green Tree will represent and
warrant that each contract is secured by a perfected security interest in the
manufactured home, and Green Tree must repurchase the contract if there is a
breach of this representation and warranty. Nevertheless, a failure by Green
Tree to perfect its security interest in the manufactured homes securing a
number of contracts could cause an increase in losses on the contracts, and
you could suffer a loss on your investment as a result.     
        
     The security interest in the manufactured home may not have been assigned
     to the trustee.     
   
     Due to the expense and administrative inconvenience, Green Tree will not
amend a certificate of title to a manufactured home to name the trustee as the
lienholder, note the trustee's interest on the certificate of title, or
deliver the certificate of title to the trustee. As a result, in some states
the assignment of the security interest in the manufactured home to the
trustee may not be effective against our creditors or a trustee in the event
we enter bankruptcy, or the security interest may not be perfected. Green Tree
also will not record the assignment to the trustee of the mortgage or deed of
trust securing land-and-home contracts because of the expense and
administrative inconvenience involved. As a result, in some states the
assignment of the mortgage or deed of trust to the trustee may not be
effective against our creditors or purchasers. If Green Tree is no longer the
servicer and the trustee or a successor servicer is unable to enforce the
security interest in the manufactured home following a default on a contract,
losses on the contracts would increase and you could suffer a loss on your
investment as a result.

      Noncompliance with consumer protection laws can make a contract partly
      unenforceable.     
   
      Numerous federal and state consumer protection laws impose requirements
on lenders under installment sales contracts and installment loan agreements
such as the manufactured home contracts. If the lender or seller of goods does
not comply with these requirements, the assignees may be liable for amounts due
under the contracts and may have the right of set-off against claims the
assignees bring. These laws would apply to the trust fund as assignee of the
manufactured home contracts. Green Tree has been involved in litigation,
including class actions, brought under consumer or debtor protection laws.
Green Tree will represent and warrant that each contract complies with
applicable federal and state consumer protection laws, and Green Tree must
repurchase the contract if there is a breach of this representation and
warranty. Nevertheless, a failure by Green Tree to comply with these laws could
cause an increase in defaults and losses on the contracts, and you could suffer
a loss on your investment as a result.     
   
If Green Tree becomes insolvent, there may be delays or reductions in
distributions to holders of certificates.     
   
      Green Tree intends to have each transfer of contracts to the related
trust fund constitute a sale, rather than a pledge of the contracts to secure
indebtedness. However, if Green Tree becomes a debtor under the federal
bankruptcy code, it is possible that Green Tree's creditors, a bankruptcy
trustee, or Green Tree as debtor-in-possession, may argue that Green Tree's
sale of the contracts was a pledge rather than a sale. If this position is
presented to or accepted by a court, it could result in a delay in or reduction
of distributions to the holders of the Certificates.     
   
      The case of Octagon Gas Systems, Inc. v. Rimmer, 995 F.2d 948 (10th Cir.
1993) contains language to the effect that accounts sold by an entity which
subsequently became bankrupt remained property of the debtor's bankruptcy
estate. Although the contracts constitute chattel paper rather than accounts
under the UCC, sales of chattel paper, like sales of accounts, are governed by
Article 9 of the UCC. If Green Tree became a debtor under the federal
bankruptcy code and a court follows the reasoning of the 10th Circuit and
applies this rule to chattel paper, holders of certificates could experience a
delay or reduction in distribution.

                          STRUCTURE OF THE TRANSACTION
   
      The Series 1999-  certificates will represent interests in a trust
consisting of a pool of manufactured housing installment sale contracts and
installment loan agreements and related property conveyed by Green Tree
Financial Corporation. Green Tree will establish the trust and transfer the
contracts and related rights to the trust under a pooling and servicing
agreement between Green Tree and [trustee], as trustee. The property of the
trust will consist of:     
       
    (1) the manufactured housing contracts, including the security interest
        in the manufactured home;     
       
    (2) Green Tree's rights under the hazard insurance policies on each
        manufactured home;     
       
    (3) all funds in the accounts we describe in this prospectus supplement;
        and     
       
    (4) all proceeds of the items in (1) through (3) above     
   
Green Tree will also service the contracts for the trust. [Custodian] will act
as custodian to hold the documents relating to all land-and-home contracts,
meaning those contracts that are primarily secured by a lien on real estate,
including the manufactured home that is considered permanently affixed to the
real estate. Green Tree will hold all the other contracts on behalf of the
trustee.     
   
      Payments by obligors on the contracts will be deposited in a separate
account maintained in the name of the trustee at least one business day after
receipt. Funds in this certificate account will be applied on each remittance
date to make the distributions to certificateholders described under
"Description of the Certificates--Distributions" and to pay monthly fees to
Green Tree as compensation for servicing the contracts.     
   
      Terms used and not otherwise defined in this prospectus supplement have
the meanings given to those terms in the prospectus.     
 
                               THE CONTRACT POOL
   
      This prospectus supplement contains information regarding the initial
contracts, which consist of manufactured housing installment sale contracts and
installment loan agreements originated through        , 1999. The pooling and
servicing agreement provides that Green Tree will transfer additional
manufactured housing contracts to the trust on the closing date and that, if
necessary, Green Tree will transfer other subsequent manufactured housing
contracts to the trust from time to time after the closing date until      ,
1999. Although the additional contracts and the subsequent contracts will have
characteristics that differ somewhat from the initial contracts we describe in
this prospectus supplement, we do not expect that the characteristics of the
additional contracts and the subsequent contracts will vary materially from the
initial contracts. In addition, the additional contracts and subsequent     
 
                                      S-15
<PAGE>
 
   
contracts must conform to the representations and warranties in the pooling and
servicing agreement. See "Description of the Certificates" in this prospectus
supplement.     
   
      The trust is entitled to all payments due or made on each contract on or
after the cut-off date for that contract. The "cut-off date" for the initial
contracts and the additional contracts is        , 1999, or the date of
origination, if later. For the subsequent contracts purchased on or before
 , 1999, the cut-off date is       , 1999, or the date of origination, if
later. For the subsequent contracts purchased from       through       , 1999,
the cut-off date is       , 1999, or the date of origination, if later. For the
subsequent contracts purchased on or after       , 1999, the cut-off date is
      , 1999, or the date of origination, if later.     
   
      Green Tree expects that the contracts will have an aggregate principal
balance as of the date of their transfer to the trust of approximately
$           . The initial contracts have an aggregate principal balance as of
their cut-off date of $           , or approximately   % of the contract pool.
All of the contracts will have been originated by a manufactured housing dealer
and purchased by Green Tree from the dealer, or will have been originated by
Green Tree directly. The contracts will have been originated or acquired by
Green Tree in the ordinary course of business.     
   
      Manufactured housing installment sale contracts and manufactured housing
installment loan agreements are referred to in this prospectus supplement as
"manufactured housing contracts" or "contracts." Each contract will be secured
by a manufactured home or, in the case of a land-and-home contract, will be
secured by a lien on real estate to which the manufactured home is deemed
permanently affixed. As of the cut-off date, a total of      , or      % by
aggregate principal amount of the initial contracts, were land-and-home
contracts.     
   
      Each contract will bear a fixed contract rate of interest. Most of the
contracts, other than "step-up rate" contracts, provide for level payments over
the entire term of the contract. Of the initial contracts, a total of    , or
    % by aggregate principal amount, are step-up rate contracts. The contract
rate of a step-up rate contract steps up on a particular date from its initial
contract rate. A total of    step-up rate contracts, or     % of the initial
contracts by aggregate principal amount, provide for two increases in the
contract rate from the initial contract rate and the remaining step-up rate
contracts provide for a single increase in the contract rate. All of the
initial contracts that are step-up rate contracts are still bearing interest at
their initial contract rate. We refer to the period during which these
contracts bear interest at their initial contract rate as the low rate period.
During the low rate period, the total amount and the principal portion of each
scheduled payment is determined on a basis that would cause the contract to be
fully amortized over its term if the contract were to bear interest during its
entire term at its initial contract rate and were to have level payments over
its entire term. The total amount and principal portion of each scheduled
payment due after the end of the applicable low rate period is determined on a
basis that would cause the contract, which would then be bearing interest at a
stepped-up rate, to be fully amortized over its remaining term on a level-
payment basis. Of the initial contracts, the low rate periods     
 
                                      S-16
<PAGE>
 
   
for those step-up rate contracts providing for a single increase in the
contract rate will end no earlier than      1999 and no later than     2000.
The contract rates for these step-up rate contracts will increase by     % or
     %. Of the initial contracts, the low rate periods for those step-up rate
contracts providing for two increases in the contract rate will end no later
than      2000, and the period with the interim applicable contract rate will
end in      2001. The contract rates for these step-up rate contracts will
increase first by     % and then by an additional     %. The combined increases
in scheduled payments for all step-up rate contracts range from $      to
$       per month. The statistical information concerning the initial contracts
which is described below, to the extent it relates to the contract rates of the
step-up rate contracts, takes into account only their contract rates as of the

      The initial contracts were originated between      1985 and        .
Approximately  % of the aggregate principal amount of the initial contracts is
attributable to loans to purchase manufactured homes which were new and
approximately   % is attributable to loans to purchase manufactured homes which
were used at the time the related initial contract was originated. All of the
initial contracts are conventional contracts and none are FHA-insured or VA-
guaranteed. The contract rate on the initial contracts ranged from     % to
     % with a weighted average of approximately     %. The initial contracts
have remaining maturities, as of the cut-off date, of at least   months but not
more than    months and original maturities of at least   months but not more
than    months, and a weighted average remaining term to scheduled maturity, as
of the cut-off date, of    months. The average remaining principal balance per
initial contract as of the cut-off date was $           and the outstanding
principal balances of the initial contracts as of the cut-off date ranged from
$   to $           . The obligors on the initial contracts are located in
states. The obligors on approximately     % of the initial contracts by
remaining principal balance are located in       ,     % in    ,     % in    ,
    % in    ,     % in     and     % in    . No other state represented more
than 5% of the initial contracts.

Tree has from time to time subserviced manufactured housing contracts
originated by other lenders. These subserviced contracts are not reflected in
the following table. The information for December 31, 1996 and later does not
include as delinquent those manufactured housing contracts whose obligors have
entered bankruptcy proceedings and had their scheduled payment changed under a
bankruptcy payment plan, provided that such obligors are current under their

      The data presented in the tables above are for illustrative purposes only
and there is no assurance that the delinquency, loan loss or repossession
experience of the contracts owned by the trust will be similar to that shown
above. The delinquency, loan loss and repossession experience of manufactured
housing contracts historically has been sharply affected by a downturn in
regional or local economic conditions. These regional or local economic
conditions are often volatile, and we cannot predict future economic conditions
in any particular area. These downturns have tended to increase the severity of
loss on repossession because of the increased supply of used units, which in
turn may affect the supply in other regions. In order to achieve geographic
dispersion and to limit the effect of regional and local economic conditions on
the contract pool, contracts with obligors located in any one state generally
will not exceed 10% of the cut-off date pool principal balance. However, it is
possible that one or more states would exceed this threshold after the transfer
of all the additional contracts.

Ratio of Earnings to Fixed Charges for Green Tree     
   
      The table below shows Green Tree's ratios of earnings (losses) to fixed
charges for the past five years and the      months ended         . For the
purposes of compiling these ratios, earnings (losses) consist of earnings
(losses) before income taxes plus fixed charges. Fixed charges consist of
interest expense and the interest portion of rent expense.

Recent Developments
   
      Green Tree has been served with various lawsuits in the United States
District Court for the District of Minnesota. These lawsuits were filed by
stockholders of Green Tree as purported class actions on behalf of persons or
entities who purchased common stock or traded in options during the alleged
class periods. In addition to Green Tree, current and former officers and
directors of Green Tree are named as defendants in one or more of the lawsuits.
The lawsuits have been consolidated into two complaints, one relating to an
alleged class of purchasers of Green Tree's common stock and the other relating
to an alleged class of traders in options for Green Tree's common stock. In
addition to these two complaints, a separate non-class action lawsuit
containing similar allegations was also filed. Plaintiffs in the lawsuits
assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of
1934. In each case, plaintiffs allege that Green Tree and the other defendants
violated federal securities laws by making false and misleading statements
about the current state and future prospects of Green Tree particularly about
prepayment assumptions and performance of some of Green Tree's loan portfolios,
which allegedly rendered Green Tree's financial statements false and
misleading. Green Tree believes that the lawsuits are without merit and intends
to defend the lawsuits vigorously.

                      YIELD AND PREPAYMENT CONSIDERATIONS
   
      The following information supplements, and if inconsistent supersedes,
the information in the prospectus under the heading "Yield Considerations."
       
      The contracts will have original terms to scheduled maturity ranging from
approximately    months to     months, but may be prepaid in full or in part at
any time. The prepayment experience of the contracts, including prepayments due
to liquidations of defaulted contracts, will affect the average life of the
certificates. Based on Green Tree's experience with the portfolio of
manufactured housing contracts it services, Green Tree anticipates that a
number of the contracts will be prepaid before their maturity. A number of
factors, including homeowner mobility, general and regional economic conditions
and prevailing interest rates, may influence prepayments. Natural disasters may
also influence prepayments. In addition, repurchases of contracts due to
breaches of representations and warranties, including repurchases of staged-
funding contracts that have not been fully disbursed within 90 days, have the
effect of prepaying such contracts and therefore would affect the average life
of the certificates. Approximately   % of the initial contracts by aggregate
principal balance as of the cut-off date were staged-funding contracts. The
prepayment experience on manufactured housing contracts varies greatly. Most of
the contracts contain a due-on-sale clause that would permit the servicer to
accelerate the maturity of a contract upon the sale of the related manufactured
home. In the case of those contracts that do contain due-on-sale clauses, Green
Tree will permit assumptions of those contracts if the purchaser of the related
manufactured home satisfies Green Tree's then-current underwriting standards.
See "Maturity and Prepayment Considerations" in the prospectus.     
   
      The allocation of distributions to the Class A certificateholders on each
remittance date on which the Class M-1 distribution test is not satisfied, on
each remittance date on which the Class M-2 distribution test is not satisfied,
or on each remittance date on which the Class B distribution test is not
satisfied, will have the effect of accelerating the amortization of the Class A
certificates from the amortization that would be applicable if the principal
were distributed pro rata according to the Class A principal balance, the Class
M-1 principal balance, the Class M-2 principal balance and the Class B
principal balance. If the Class A certificates are purchased at a discount and
the purchaser calculates its anticipated yield to maturity based on an assumed
rate of payment of principal on the Class A certificates that is faster than
the rate actually realized, the purchaser's actual yield to maturity will be
lower than the yield calculated by the purchaser. See "Description of the
Certificates--Class A Principal."     
   
      On any remittance date on which the Class M-1 distribution test, the
Class M-2 distribution test and the Class B distribution test is not satisfied,
the Class A certificateholders will receive 100% of the Formula Principal
Distribution Amount, as described under "Description of the Certificates--Class
A Principal," subject to the limit of the amount available for distribution.
The rate of principal payments on the Class M-1 certificates, Class M-2
certificates and Class B certificates and the aggregate amount of distributions
on the Class M-1 certificates, Class M-2 certificates and Class B certificates
will be affected by the rate of obligor defaults resulting in delinquencies on
    
                                      S-25
<PAGE>
 
   
the contracts and losses on liquidated contracts, by the severity of those
losses and by the timing of those delinquencies and losses. See "Description of
the Certificates--Subordination of Class M-1 Certificates, Class M-2
Certificates, Class B Certificates, Class B-3I Certificates and Class C
Certificates" for a description of the manner in which such losses are borne by
the Class M-1 certificates, the Class M-2 certificates and each class of the
Class B certificates. If you purchase a class of Class B certificates, Class M-
2 certificates or Class M-1 certificates at a discount and you calculate your
anticipated yield to maturity based on an assumed rate of payment of principal
on the Class B certificates, Class M-2 certificates or Class M-1 certificates
that is faster than the rate actually realized, your actual yield to maturity
will be lower than the yield you calculated. See "Description of the
Certificates--Class B-1 Principal."     
   
      Obligors who have entered bankruptcy proceedings and have had their
monthly scheduled payment reduced as a result of an extension of the term of
the related contract may not be pursued by Green Tree as delinquent, and
accordingly Green Tree uses the reduced monthly payment in calculating the
Formula Principal Distribution Amount for each remittance date thereafter. If,
however, the principal amount of the contract were reduced in the bankruptcy
proceedings, the reduction would be recognized as a loss immediately and added
to the Formula Principal Distribution Amount.     
   
      We cannot assure you that the delinquency or repossession experience set
forth under "Green Tree Financial Corporation--Delinquency, Loan Loss and
Repossession Experience" will be representative of the results that may be
experienced on the contracts.     
   
      Green Tree and the servicer each have the option to purchase from the
trust all remaining contracts, and effect early retirement of the certificates,
on any remittance date when the pool scheduled principal balance is less than
10% of the cut-off date pool principal balance. See "Description of the
Certificates--Repurchase Option."     
   
      If the aggregate principal balance of the initial and additional
contracts transferred to the trust on the closing date is less than the
aggregate original principal balance of the certificates, a pre-funding account
will be established by the trustee and funded by Green Tree on the closing date
to provide the trust with sufficient funds to purchase subsequent contracts.
Any amounts remaining in the pre-funding account which have not been used to
purchase subsequent contracts will be paid to the Class A-1 certificateholders
no later than        . Green Tree believes that if a pre-funding account is
established, substantially all of the amounts in the account will be used to
acquire subsequent contracts. It is unlikely, however, that the aggregate
principal amount of subsequent contracts purchased by the trust will be
identical to the amount in the pre-funding account, and consequently, Class A-1
certificateholders will receive some prepayment of principal. See "Description
of Certificates--Conveyance of Subsequent Contracts and Pre-Funding Account."
       
      Although partial prepayments of principal on contracts are applied on
scheduled payment dates for the contracts, obligors are not required to pay
interest on contracts     
 
                                      S-26
<PAGE>
 
   
after the date of a full prepayment of principal. As a result, full prepayments
on contracts in advance of the scheduled payment dates for these contracts in
any due period will reduce the amount of interest received from obligors during
the due period. Subject to the availability of the subordination provided by
the Class M-1, Class M-2, Class B-1, Class B-2, Class B-3I and Class C
certificates, the subordination would apply to the net shortfall of interest
received on account of prepayments in full in any due period so that the amount
of interest paid on the Class A certificates on the following remittance date
would not be affected by the shortfall.     
   
      The expected final scheduled payment date on the initial contract with
the latest maturity is in         . The expected final maturity of each class
of certificates, based on the assumptions that there are no defaults,
prepayments or delinquencies on payments due under the contracts and that the
repurchase option has not been exercised, are as follows:     
       
    .     for the Class A-2 certificates,     
         
      .   for the Class A-3 certificates,     
         
      .   for the Class A-4 certificates,     
         
      .   for the Class A-5 certificates,     
         
      .   for the Class A-6 certificates,     
         
      .   for the Class A-7 certificates,     
         
      .   for the Class M-1 certificates,     
         
      .   for the Class M-2 certificates,     
         
      .   for the Class B-1 certificates, and     
         
      .   for the Class B-2 certificates.     
   
      The table below shows statistical information about the prepayment
behavior of pools of manufactured housing contracts sold and serviced by Green
Tree. The table relates to Green Tree's 40 sold pools for which prepayment
information is available covering a period of at least 36 months and which had
an aggregate principal balance as of the first day of the month of sale of at
least $100,000,000. In evaluating the information in the table and its
relationship to the expected prepayment behavior of the contracts, you should
consider that Green Tree has performed no statistical analysis to determine
whether the contracts to which the table relates constitute a statistically
significant sample of manufactured housing contracts for purposes of
determining expected prepayment behavior. Also, the contracts owned by the
trust may have an average age as of the cut-off date substantially different
from the average ages, as of the first day of the month of sale, of the
contracts in the sold pools to which the table relates and may have other
characteristics substantially different from the contracts in any sold pool.
For these reasons, and because of the unpredictable nature of the factors
described under "Weighted Average Life of the Class A, Class M-1, Class M-2 and
Class B Certificates" which may influence the amount of prepayments of
manufactured housing contracts, we cannot assure you that the prepayment
experience of the contracts will exhibit prepayment behavior similar to the
behavior summarized in the table for the     
 
                                      S-27

periods covered. In addition, prospective Class A, Class M-1, Class M-2 and
Class B certificateholders should consider that the table is limited to those
periods covered and cannot reflect any effects of aging on the prepayment
behavior of manufactured housing contracts beyond those periods.     
         
      The table below shows for each sold pool:     
       
    .  the initial aggregate principal balance, calculated as of the first
       day of the month of the sale,     
       
    .  the weighted average contract rate ("WAC") of the contracts in each
       pool as of the first day of the month of the sale of each pool,

       each pool,

Weighted Average Life of the Class A, Class M-1, Class M-2 and Class B
Certificates
   
      The following information is intended to illustrate the effect of
prepayments of the initial contracts on the weighted average life of the Class
A certificates, Class M-1 certificates, Class M-2 certificates and Class B
certificates under the stated assumptions and is not a prediction of the
prepayment rate that the contracts might actually experience.     
   
      Weighted average life refers to the average amount of time from the date
of issuance of a security until each dollar of principal of such security will
be repaid to the investor. The weighted average life of the Class A, Class M-1,
Class M-2 and Class B certificates will be influenced by the rate at which
principal on the contracts is paid. Principal payments on contracts may be in
the form of scheduled amortization or prepayments. For this purpose, the term
"prepayment" includes repayments and liquidations due to default or other
dispositions of Contracts. Prepayments on contracts may be measured by a
prepayment standard or model. The model we use in this prospectus supplement,
the manufactured housing prepayment model ("MHP"), is based on an assumed rate
of prepayment each month of the then unpaid principal balance of a pool of new
contracts. A prepayment assumption of 100% MHP assumes constant prepayment
rates of 3.7% per year of the then unpaid principal balance of the contracts in
the first month of the life of the contracts and an additional 0.1% per year in
each month thereafter until the 24th month. Beginning in the 24th month and in
each month thereafter during the life of all of the contracts, 100% MHP assumes
a constant prepayment rate of 6.0% per year each month.     
   
      As used in the following tables "75% MHP" assumes the contracts will
prepay at rates of 75% of the MHP assumed prepayment rates; 150% assumes the
contracts will prepay at rates of 150% of the MHP assumed prepayment rates, and
so forth.     
   
      We cannot assure you, however, that prepayment of the contracts owned by
the trust will conform to any level of the MHP, and we make no representation
that the contracts will prepay at the prepayment rates shown or any other
prepayment rate. The rate of principal payments on pools of manufactured
housing contracts is influenced by a variety of economic, geographic, social
and other factors, including the level of interest rates and the rate at which
homeowners sell their manufactured homes or default on their contracts.
Increased competition among manufactured housing lenders and recently declining
interest rates have had the effect of increasing the prepayment rates of Green
Tree's contracts. Other factors affecting prepayment of contracts include
changes in obligors' housing needs, job transfers, unemployment and obligors'
net equity in the manufactured homes. In the case of mortgage loans secured by
site-built homes, in general, if prevailing interest rates fall significantly
below the interest rates on these mortgage loans, the mortgage loans are likely
to be subject to higher prepayment rates than if prevailing interest rates
remained at or above the rates borne by these mortgage loans. Conversely, if
prevailing interest rates rise above the interest rates on the mortgage loans,
the rate of prepayment would be expected to decrease. In the case of
manufactured housing contracts, however, because the outstanding principal
balances are, in general, much smaller than mortgage loan balances and the
original     
 
                                      S-30
<PAGE>
 
   
term to maturity of the contracts is generally shorter, the reduction or
increase in the size of the monthly payment on a contract arising from a change
in its interest rate is generally much smaller. Consequently, changes in
prevailing interest rates may not have a similar effect, or may have a similar
effect but to a smaller degree, on the prepayment rates on manufactured housing
contracts.     
   
      As described under "Description of the Certificates--Class M-1
Principal," payments of principal on the Class M-1 certificates will not
commence until the remittance date on which (1) the Class A principal balance
has been reduced to zero or (2) the Class M-1 distribution test is satisfied.
This will have the effect of accelerating the amortization of the Class A
certificates while increasing the respective interest in the trust of the Class
M-1, Class M-2 and Class B certificates. As described under "Description of the
Certificates--Class M-2 Principal," payments of principal on the Class M-2
certificates will not commence until the remittance date on which (a) the Class
A principal balance and Class M-1 principal balance have been reduced to zero
or (b) the Class M-2 distribution test is satisfied. This will have the effect
of accelerating the amortization of the Class A certificates and Class M-1
certificates while increasing the respective interest in the trust of the Class
M-2 certificates and Class B certificates. As described under "Description of
the Certificates--Class B-1 Principal," payments of principal on the Class B
certificates will not commence until the remittance date on which (1) the Class
A principal balance, the Class M-1 principal balance and the Class M-2
principal balance have been reduced to zero or (2) the Class B distribution
test is satisfied. This will have the effect of accelerating the amortization
of the Class A certificates, Class M-1 certificates and Class M-2 certificates
while increasing the respective interest in the trust of the Class B
certificates.     
   
      The percentages and weighted average lives in the following tables were
determined assuming that:     
       
    (1) scheduled interest and principal payments on the contracts are
        received in a timely manner and prepayments are made at the
        indicated percentages of the MHP listed in the table;     
       
    (2) either Green Tree or the servicer exercises its right of optional
        termination described above;     
       
    (3) the aggregate principal balance of the initial contracts as of the
        cut-off date is $     and the initial contracts have the
        characteristics described under "The Contract Pool" and have their
        first scheduled payment due in    , 1999;     
       
    (4) the additional contracts and subsequent contracts will have the
        characteristics listed in the table following this paragraph and
        will have their first scheduled payment due in     and     1999;
               
    (5) each class of certificates has the approximate principal amount and
        the remittance rate shown for that class under "Summary of the Terms
        of the Offered Certificates" in this prospectus supplement;     
       
    (6) no interest shortfalls will arise because of prepayment in full of
        the contracts;

    (7) no delinquencies or losses are experienced on the contracts;     
       
    (8) distributions are made on the certificates on the first day of each
        month, commencing in     1999; and     
       
    (9) the certificates are issued on    , 1999.     
   
We make no representation that the contracts will not experience delinquencies
or losses.

      It is not likely that contracts will prepay at any constant percentage of
the MHP to maturity or that all contracts will prepay at the same rate.     
 
      Investors are urged to make their investment decisions on a basis that
includes their determination as to anticipated prepayment rates under a variety
of the assumptions discussed herein.
   
      Based on the foregoing assumptions, the following tables indicate the
projected weighted average life of the Class A-1 certificates, the Class A-2
certificates, the Class A-3 certificates, the Class A-4 certificates, the Class
A-5 certificates, the Class A-6 certificates, the Class A-7 certificates, the
Class M-1 certificates, the Class M-2 certificates, the Class B-1 certificates
and the Class B-2 certificates and show the percentages of the original Class
A-1 principal balance, the original Class A-2 principal balance, the original
Class A-3 principal balance, the original Class A-4 principal balance, the
original Class A-5 principal balance, the original Class A-6 principal balance,
the original Class A-7 principal balance, the original Class M-1 principal

      The weighted average life of each class of each of certificates listed in
the tables below is determined by (1) multiplying the amount of cash
distributions in reduction of the principal balance of the certificate by the
number of years from the date of issuance of certificate to the stated
remittance date, (2) adding the results, and (3) dividing the sum by the
initial principal balance of the certificate.

                        DESCRIPTION OF THE CERTIFICATES
   
      The following information supplements, and if inconsistent supersedes,
the information in the prospectus under "Description of the Certificates."     
   
      The certificates will be issued under the pooling and servicing
agreement. A copy of the execution form of the agreement will be filed in a
current report on Form 8-K with the Securities and Exchange Commission after
the initial issuance of the certificates. The following summary describes
certain terms of the pooling and servicing agreement, does not purport to be
complete and is qualified in its entirety by the pooling and servicing
agreement, which is incorporated by reference in this prospectus supplement.
    
General
   
      The certificates will be issued in fully registered form only in
denominations of $1,000 or an integral multiple of $1,000. The percentage
interest of a Class A certificate will be equal to the percentage obtained from
dividing its denomination by the original Class A-1 principal balance, the
original Class A-2 principal balance, the original Class A-3 principal balance,
the original Class A-4 principal balance, the original Class A-5 principal
balance, the original Class A-6 principal balance or the original Class A-7
principal balance, as appropriate. The Class A certificates in the aggregate
will represent approximately an initial   % undivided interest in the trust.
The percentage interest of a Class M-1 certificate will be equal to the
percentage obtained by dividing its denomination by the original Class M-1
principal balance. The Class M-1 certificates in the aggregate will represent
approximately an initial   % undivided interest in the trust. The percentage
interest of a Class M-2 certificate will be equal to the percentage obtained by
dividing its denomination by the original Class M-2 principal balance. The
Class M-2 certificates in the aggregate will represent approximately an initial
  % undivided interest in the trust. The percentage interest of a Class B
certificate will be equal to the percentage obtained from dividing its
denomination by the original Class B-1 principal balance or the original Class
B-2 principal balance, as appropriate. The Class B certificates in the
aggregate will represent approximately an initial   % undivided interest in the
trust.     
   
      The paying agent will make distributions on the certificates each
remittance date to persons in whose names the certificates are registered as of
the preceding record date. The remittance date for the certificates will be the
first day of each month or, if the first day is not a business day, the next
succeeding business day, commencing in     1999. Payments will be made by check
mailed on the remittance date to the Certificateholder at the address appearing
on the certificate register; provided that a certificateholder who holds an
aggregate percentage interest of at least 5% of a class of certificates may
request payment by wire transfer of immediately available funds pursuant to
written instructions delivered to the trustee at least 10 days before the
remittance date. Final payments will be made only when of the certificates are
tendered to the paying agent for cancellation. (Articles I and VIII.)

Conveyance of Contracts
   
      On the closing date, Green Tree will establish the trust and transfer to
the trust the initial and additional contracts, including all principal and
interest received on the Contracts other than receipts of principal and
interest due on the contracts before the cut-off date. The pooling and
servicing agreement permits the trust to purchase subsequent contracts on one
or more subsequent transfer dates through      , 1999. See "Conveyance of
Subsequent Contracts and Pre-Funding Account" in this prospectus supplement.
       
      In addition to the representations and warranties described in the
prospectus under "Description of Certificates--Conveyance of Contracts, " Green
Tree will make warranties about the initial contracts, including that:     
       
    (1) the aggregate principal amount payable by the obligors on the
        initial contracts as of the cut-off date equals $     ;     
       
    (2) as of the cut-off date, the obligors on no more than 10% of the
        initial contracts by remaining principal balance are located in any
        one state, the obligors on no more than 5% of the initial contracts
        by remaining principal balance are located in an area with the same
        zip code and the obligors on not more than 1% of the initial
        contracts by remaining principal balance are located in California
        in an area with the same zip code;     
       
    (3) approximately  % of the aggregate principal amount of initial
        contracts as of the cut-off date is attributable to loans to
        purchase new manufactured homes and approximately  % is attributable
        to loans to purchase used manufactured homes;     
       
    (4) no initial contract has a remaining maturity of more than 360
        months;     
       
    (5) the date of each initial contract is on or after         ; and     
       
    (6) no adverse selection procedures were employed in selecting the
        initial contracts.     
   
Green Tree will make additional representations and warranties about the
additional contracts and subsequent contracts.     
 
Conveyance of Subsequent Contracts and Pre-Funding Account
   
      If the aggregate principal balance of the initial and additional
contracts transferred to the trust on the closing date is less than the
aggregate original principal balance of the certificates, a pre-funding account
will be established by the trustee and funded by Green Tree on the closing date
to provide the trust with sufficient funds to purchase subsequent contracts.
The amount deposited in the pre-funding account will initially equal the
difference between $      and the aggregate principal balance as of the cut-off
date of the initial contracts and additional contracts. The pre-funding account
will be used to purchase subsequent contracts during the pre-funding period
from the closing date until the earliest of (1) the date on which the amount in
the pre-funding account is less than $10,000, (2)      , 1999, or (3) the date
on which an     
 
                                      S-41
<PAGE>
 
   
event of termination occurs under the pooling and servicing agreement. Any
reinvestment income earned on amounts on deposit in the pre-funding account
will be taxable to Green Tree.     
   
      Under the pooling and servicing agreement, following the initial issuance
of the certificates, the trust will be obligated to purchase subsequent
contracts from Green Tree during the pre-funding period, subject to their
availability. Each subsequent contract will have been underwritten in
accordance with Green Tree's standard underwriting criteria. Subsequent
contracts will be transferred to the Trust under subsequent transfer
instruments between Green Tree and the trust. In connection with the purchase
of subsequent contracts on the subsequent transfer dates, the trust will be
required to pay to Green Tree from amounts on deposit in the pre-funding
account a cash purchase price of 100% of the contract's principal balance as of
the cut-off date. The amount paid from the pre-funding account on each
subsequent transfer date will not include accrued interest on the related
subsequent contracts. Following each subsequent transfer date, the aggregate
principal balance of the contracts in the trust will increase by an amount
equal to the aggregate principal balance of the contracts purchased and the
amount in the pre-funding account will decrease by the same amount. Any amounts
remaining in the pre-funding account after the purchase of subsequent contracts
will be applied on the first remittance date on or after the last day of the
pre-funding period to prepay principal on the Class A-1 certificates.     
   
      Any conveyance of subsequent contracts on a subsequent transfer date is
subject to conditions including:     
       
    (1) each subsequent contract must satisfy the representation and
        warranties specified in the related subsequent transfer instrument
        and the pooling and servicing agreement;     
       
    (2) Green Tree must not select subsequent contracts in a manner that it
        believes is adverse to the interests of the certificateholders;     
       
    (3) as of its respective cut-off date, each subsequent contract must
        satisfy the following criteria:     
                
             .  no subsequent contract may be more than 30 days contractually
                delinquent;     
                
             .  the remaining stated term to maturity of each subsequent
                contract may not exceed 360 months;     
                
             .  each subsequent contract must be underwritten in accordance
                with Green Tree's standard underwriting criteria; and     
                
             .  no subsequent contract may have a loan-to-value ratio greater
                than 100%;     
       
    (4) the contract pool following the addition of the subsequent contracts
        must satisfy the following criteria:     
                
             .  the weighted average contract rate must not be less than   %;
                       
             .  the weighted average loan-to-value ratio must not be greater
                than  %;     
 
                                      S-42
<PAGE>
 
                
             .  not less than  % of the cut-off date pool principal balance
                must be attributable to loans to purchase new manufactured
                homes;     
                
             .  not more than  % of the cut-off date pool principal balance
                must be secured by single-wide manufactured homes and not less
                than  % of the cut-off date pool principal balance must be
                secured by double-wide manufactured homes; and     
                
             .  at least  % of the cut-off date pool principal balance must
                consist of land-and-home contracts;

        will not receive from S&P or Fitch a lower credit rating than the
        rating assigned at the initial issuance of the class of
        certificates; and     
       
    (6) an independent accountant will provide a letter stating whether or
        not the characteristics of the subsequent contracts conform to the
        characteristics described in this prospectus supplement.     
 
Payments on Contracts; Distributions on Certificates
   
      The trustee, on behalf of the trust, will establish and maintain the
certificate account in an eligible account. (Section 1.02.) "Eligible account"
means any account which is     
       
    (1) an account maintained with an "eligible institution"; or     
       
    (2) a "segregated trust account" maintained with the corporate trust
        department of a federal or state chartered depository institution or
        trust company with trust powers and acting in its fiduciary capacity
        for the benefit of the trustee, which depository institution or
        trust company has capital and surplus or, if the depository
        institution or trust company is a subsidiary of a bank holding
        company system, the capital and surplus of the bank holding company
        of not less than $50,000,000 and the securities of the depository
        institution or trust company (or, if the depository institution or
        trust company is a subsidiary of a bank holding company system and
        the depository institution's or trust company's securities are not
        rated, the securities of the bank holding company) has a credit
        rating from Moody's, if rated by Moody's, S&P, if rated by S&P and
        Fitch, if rated by Fitch, in one of its generic credit rating
        categories which signifies investment grade; or     
       
    (3) an account that will not cause S&P or Fitch to downgrade or withdraw
        its then-current rating assigned to the certificates, as confirmed
        in writing by S&P and Fitch.     
   
"Eligible institution" means any depository institution organized under the
laws of the United States or any state, the deposits of which are insured to
the full extent permitted by law by the Bank Insurance Fund, currently
administered by the Federal Deposit Insurance Corporation, whose short-term
deposits have been rated P-1 by Moody's, if rated by Moody's, A-1+ by S&P, if
rated by S&P and F-1 by Fitch, or in one of the two highest rating categories

and Fitch in the case of unsecured long-term debt, and which is subject to
supervision and examination by federal or state authorities. The servicer may
authorize the trustee to invest the funds in the certificate account in
eligible investments that will mature not later than the business day before
the applicable monthly remittance date. "Eligible investments" are defined in
the pooling and servicing agreement and include:     
     
  .  direct obligations of, and obligations fully guaranteed by, the United
     States or of any agency backed by the full faith and credit of the
     United States and which are noncallable;     
     
  .  federal funds, certificates of deposit, time deposits and bankers'
     acceptances sold by eligible financial institutions;     
     
  .  repurchase agreements with eligible institutions;

     Fitch, not in excess of 10% of amounts in the certificate account at the
     time of the investment;     
     
  .  commercial paper assigned at least a P-1 rating by Moody's and at least
     an A-1+ rating by S&P, if rated by S&P, at the time of the investment;
     and     
     
  .  shares of registered investment companies whose shares are registered
     under the Securities Act of 1933 and have the highest credit rating then
     available from Moody's and Fitch, if rated by Fitch, and are rated AAAm
     or AAAm-G by S&P.     
   
      All payments from obligors on the contracts which the servicer receives,
including principal prepayments and advance payments by obligors not
constituting principal prepayments, must be paid into the certificate account
no later than one business day after receipt of the payment, except amounts
received as late payment fees, extension fees, assumption fees or similar
fees. These fees are included as part of the servicer's servicing fees. See
"Servicing Compensation and Payment of Expenses" in the prospectus. In
addition, amounts paid by Green Tree for contracts repurchased as a result of
breach of warranties under the pooling and service agreement, and amounts
required to be deposited upon substitution of a contract because of breach of
warranties, as described under "Conveyance of Contracts" in the prospectus,
must be paid into the certificate account. The servicer will not make any
advances in respect of delinquent payments on the contracts.     
   
      On the third business day before each remittance date, the servicer will
determine the amount available and the amounts to be distributed on the
certificates for that remittance date. The amount available on each remittance
date generally includes:     
       
    (1) payments on the contracts due and received during the related due
        period (as defined in the next paragraph),     
       
    (2) prepayments and other unscheduled collections received during the
        related due period,     
       
    (3) all collections of principal on the contracts received during the
        due period in which the remittance date occurs up to and including
        the third business day     
 
                                     S-44
<PAGE>
 
          
       before the remittance date, but in no event later than the 25th day
       of the month before the remittance date, minus     
       
    (4) for all remittance dates other than the remittance date in     1999,
        all collections in respect of principal on the contracts received
        during the related due period up to and including the third business
        day before the preceding remittance date, but in no event later than
        the 25th day of the prior month.     
   
The amount available will be reduced by the following amounts:     
       
    .advance payments in respect of the related due period;     
       
    .  amounts payable to the servicer to reimburse it for any REMIC
       prohibited transaction tax imposed on the trust and paid by the
       servicer;     
       
    .  liquidation expenses incurred and taxes and insurance on repossessed
       manufactured homes, advanced by the servicer for manufactured homes
       that are reimbursable to the servicer under the pooling and
       servicing agreement; and     
       
    .  any amounts incorrectly deposited in the certificate account.     
   
Liquidation expenses are out-of-pocket expenses incurred by the servicer in
connection with the liquidation of a defaulted contract, including, without
limitation, legal fees and disbursements. (Sections 1.02 and 8.02.)     
   
      The "due period" for all remittance dates, other than the remittance date
in     1999, is the period from and including the 15th day of the second month
preceding that remittance date, to and including the 14th day of the month
immediately preceding that remittance date. For the remittance date in
1999, the due period will be the period from and including     1, 1999 to and
including     14, 1999.     
   
      The trustee will withdraw funds from the certificate account to make
payments to certificateholders. From time to time, as provided in the pooling
and servicing agreement, the trustee will also withdraw funds from the
certificate account to make payments to the servicer. (Sections 1.02 and 8.02.)
    
Distributions
   
      On each remittance date, distributions on the certificates will be made
first with respect to interest on the Class A certificates, then with respect
to interest on the Class M-1 certificates, then with respect to interest on the
Class M-2 certificates, then with respect to interest on the Class B-1
certificates, then with respect to principal on the Class A certificates, then
with respect to principal on the Class M-1 certificates, then with respect to
principal on the Class M-2 certificates, then with respect to principal on the
Class B-1 certificates. Following distribution of interest and principal on the
Class A, Class M-1, Class M-2 and Class B-1 certificates, distributions will be
made first with respect to interest on the Class B-2 certificates, then with
respect to principal on the Class B-2 certificates, all as more fully described
in the next eleven pages.     
 
                                      S-45
<PAGE>
 
   
      Each distribution on a book-entry certificate will be paid to DTC, which
will credit the amount of the distribution to the accounts of its participants
in accordance with its normal procedures. Each participant will be responsible
for disbursing the distribution to the certificate owners that it represents
and to each indirect participating brokerage firm for which it acts as agent.
Each brokerage firm will be responsible for disbursing funds to the certificate
owners that it represents. All credits and disbursements on a book-entry
certificate are to be made by DTC and the participants in accordance with DTC's
rules.     
   
      The servicer will furnish to the trustee, and the trustee will send with
each distribution on a remittance date to each holder of the certificates, a
statement or statements describing the amount of the distribution allocable to
principal and the amount of the distribution allocable to interest. These
amounts will be expressed as a dollar amount per Class A, Class M-1, Class M-2
or Class B certificate with a 1% percentage interest or per $1,000 denomination
of Class A, Class M-1, Class M-2 or Class B certificate. (Section 6.05.)     
 
Class A Interest
   
      One month's interest will be paid to the holders of the Class A
certificates on each remittance date, to the extent of the amount available in
the certificate account on that date, at the Class A remittance rate on the
then outstanding principal balance of the Class A certificates. Interest on the
Class A certificates will accrue from      , 1999, or from the most recent
remittance date on which interest has been paid, to but excluding the following
remittance date. The interest due on the Class A-1 certificates will be
computed on the basis of the actual number of days elapsed from and including
the most recent remittance date to but excluding the current remittance date
and a 360-day year, and the interest due on all other Class A Certificates, on
the basis of a 360-day year of twelve 30-day months. (Sections 1.02 and 8.03.)
       
      The remittance rates for the Class A-1, Class A-2, Class A-3, Class A-4,
Class A-5, Class A-6 and Class A-7 certificates are listed on the cover of this
prospectus supplement.     
   
      The principal balance of any class of Class A certificates as of any
remittance date is the original principal balance of that class less all
amounts previously distributed to holders of that class on account of
principal. The Class A principal balance as of any remittance date is the sum
of the Class A-1 principal balance, the Class A-2 principal balance, the Class
A-3 principal balance, the Class A-4 principal balance, the Class A-5 principal
balance, the Class A-6 principal balance and the Class A-7 principal balance.
(Section 1.02.)     
   
      If on a particular remittance date, the amount available in the
certificate account is not sufficient to make a full distribution of interest
to the holders of the Class A certificates, the amount available will be
distributed among the outstanding Class A certificates pro rata based on the
aggregate amount of interest due on each class, and the amount of the shortfall
will be carried forward and added to the amount such holders will be entitled
to receive on the next remittance date. (Section 1.02) Such a shortfall     
 
                                      S-46
<PAGE>
 
   
could occur, for example, if delinquencies or losses realized on the contracts
were exceptionally high and were concentrated in a particular due period. Any
amount carried forward will bear interest at the remittance rate for each class
of Class A certificates, to the extent permitted by law.     
   
      The Class A-7 remittance rate on each remittance date will be   % per
year, subject to a maximum rate equal to the weighted average of the contract
rates on the contracts in the contract pool, computed on the basis of a 360-day
year of twelve 30-day months. In all but the most unusual prepayment scenarios,
we anticipate that the Class A-7 remittance rate will be   %. In the unlikely
event that a large number of contracts having contract rates higher than   %
were to prepay while the contracts having contract rates equal to or lower than
  % did not prepay, with the result that the interest collections on the
remaining contracts were not sufficient to support a Class A-7 remittance rate
of   %, then the Class A-7 remittance rate would be equal to the weighted
average of the contract rates on the contracts remaining in the contract pool.
Of the initial contracts,   % by aggregate principal balance as of the cut-off
date had contract rates higher than   %. The weighted average of the contract
rates on the initial contracts as of the cut-off date was approximately   %.
    
Class M-1 Interest
   
      Interest will be paid to the Class M-1 certificateholders on each
remittance date, to the extent of the amount available in the certificate
account after payment of interest on the Class A certificates. Interest on the
outstanding Class M-1 adjusted principal balance will accrue from     , 1999,
or from the most recent remittance date on which interest has been paid, to but
excluding the following remittance date. The Class M-1 principal balance is the
original Class M-1 principal balance less the sum of all amounts previously
distributed to Class M-1 certificateholders on account of principal. The Class
M-1 adjusted principal balance as of any remittance date is the Class M-1
principal balance less any Class M-1 liquidation loss amount. If, on a
particular remittance date, the remaining amount available in the certificate
account is not sufficient to make a full distribution of interest to the Class
M-1 certificateholders, other funds in the certificate account representing
collections received before that remittance date, up to a limited amount, will
be applied to the deficiency, and any remaining deficiency will be carried
forward and added to the amount the holders will be entitled to receive on the

Class M-1 remittance rate, to the extent permitted by law.     
   
      The Class M-1 remittance rate on each remittance date will be   % per
year, subject to a maximum rate equal to the weighted average of the contract
rates on the contracts in the contract pool, computed on the basis of a 360-day
year of twelve 30-day months. In all but the most unusual prepayment scenarios,
we anticipate that the Class M-1 remittance rate will be   %. In the unlikely
event that a large number of contracts having contract rates higher than   %
were to prepay while the contracts having contract rates equal to or lower than

Class M-2 Interest
   
      Interest will be paid to the Class M-2 Certificateholders on each
remittance date, to the extent of the amount available in the certificate
account after payment of interest on the Class A certificates and the Class M-1
certificates. Interest on the outstanding Class M-2 adjusted principal balance
will accrue from    , 1999, or from the most recent remittance date on which
interest has been paid, to but excluding the following remittance date. The
Class M-2 Principal Balance is the original Class M-2 principal balance less
the sum of all amounts previously distributed to Class M-2 certificateholders
on account of principal. The Class M-2 adjusted principal balance as of any
remittance date is the Class M-2 principal balance less any Class M-2
liquidation loss amount. If, on a particular remittance date, the remaining
amount available in the certificate account is not sufficient to make a full
distribution of interest to the Class M-2 certificateholders, other funds in
the certificate account representing collections received before that
remittance date, up to a limited amount, will be applied to the deficiency, and
any remaining deficiency will be carried forward and added to the amount the
holders will be entitled to receive on the next remittance date. Any amount
carried forward will bear interest at the Class M-2 remittance rate, to the
extent permitted by law.

      Interest will be paid to the Class B-1 certificateholders on each
remittance date, to the extent of the amount available in the certificate
account after payment of interest on the Class A certificates, Class M-1
certificates and Class M-2 certificates. Interest on the outstanding Class B-1

Class A Principal
   
      Holders of the Class A certificates will be entitled to receive a payment
of principal on each remittance date, to the extent of the amount available in
the certificate account on the date after payment of interest on the Class A
principal balance, the Class M-1 adjusted principal balance, the Class M-2
adjusted principal balance and the Class B-1 adjusted principal balance, in an
amount equal to the Class A Percentage of the "Formula Principal Distribution

      The "Scheduled Principal Balance" of a contract as of any remittance
date is the unpaid principal balance of the contract as specified in the
amortization schedule at the time relating to the contract as of the due date
in the related due period, after giving effect to any previous partial
prepayments and to the payment of principal due on the due date and
irrespective of any delinquency in payment on the contract. The "Pool
Scheduled Principal Balance" as of any remittance date is the aggregate of the
Scheduled Principal Balances of contracts outstanding at the end of the
related due period. A liquidated contract is a defaulted contract as to which
all amounts that the servicer expects to recover through the date of
disposition of the manufactured home have been received. (Section 1.02.)     
   
      The Class A Percentage of the Formula Principal Distribution Amount will
be distributed, to the extent of the amount available after payment of

Mandatory Prepayments on the Class A-1 Certificates
   
      If the aggregate principal balance of the initial and additional
contracts transferred to the trust on the closing date is less than the
aggregate original principal balance of the certificates, a pre-funding account
will be established by the trustee and funded by Green Tree on the closing
date. See "Yield and Prepayment Considerations" and "Description of the
Certificates--Conveyance of Subsequent Contracts and Pre-Funding Account.     
 
Class M-1 Principal
   
      Holders of the Class M-1 certificates will be entitled to receive a
payment of principal on each remittance date on which the Class A principal
balance has been reduced to zero or the Class M-1 distribution test is
satisfied. The amount of principal paid on the Class M-1 certificates on any
remittance date will be the Class M-1 Percentage of the Formula Principal
Distribution Amount, subject to the limit of the amount available in the
certificate account on the date remaining after payment of interest on the
Class A principal balance, the Class M-1 adjusted principal balance, the Class
M-2 adjusted principal balance and the Class B-1 adjusted principal balance and
the payment of principal due on the Class A certificates.     
         
      The "Class M-1 Percentage" for any remittance date will equal     
       
    (1) zero, if the Class A principal balance has not yet been reduced to
        zero and the Class M-1 distribution test is not satisfied, or

             (d) if the Class B distribution test is satisfied on that
                remittance date, the Class B principal balance, otherwise
                zero.     
   
      The Class M-1 distribution test will be satisfied if each of the
following tests is satisfied:     
       
    (1) the remittance date occurs in or after    ;     
       
    (2) the average sixty-day delinquency ratio test, as defined in the
        pooling and servicing agreement as of the remittance date must not
        exceed 4.50%;     
       
    (3) cumulative realized losses, as defined in the pooling and servicing
        agreement, as of the remittance date must not exceed a certain
        specified percentage of the cut-off date pool principal balance,
        depending on the year in which the remittance date occurs;     
       
    (4) the current realized loss ratio, as defined in the agreement, as of
        the remittance date must not exceed 2.75%; and     
       
    (5) the sum of the Class M-1 principal balance, the Class M-2 principal
        balance and the Class B principal balance divided by the pool
        scheduled principal balance as of the immediately preceding
        remittance date must be equal to or greater than   %.     
   
      After payment of all principal then distributable on the Class M-1
certificates, any Class M-1 liquidation loss interest amount that has accrued
and has not previously been paid will be distributed, together with interest on
that amount at the Class M-1 remittance rate to the extent legally permissible,
to the extent of the remaining amount available.     
 
Class M-2 Principal
   
      Holders of the Class M-2 Certificates will be entitled to receive a
payment of principal on each remittance date on which the Class A principal
balance and the Class M-1 principal balance have been reduced to zero or the
Class M-2 distribution test is satisfied. The amount of principal paid on the
Class M-2 certificates on any remittance date will be the Class M-2 Percentage
of the Formula Principal Distribution Amount, subject to the limit of the
amount available in the certificate account on the date remaining after payment
of interest on the Class A principal balance, the Class M-1 adjusted principal
balance, the Class M-2 adjusted principal balance and the Class B-1 adjusted
principal balance and the payment of principal due on the Class A and Class M-1
certificates.

      The Class M-2 distribution test will be satisfied if each of the
following tests is satisfied:     
       
    (1) the remittance date occurs in or after    ;     
       
    (2) the average sixty-day delinquency ratio test as defined in the

    (3) cumulative realized losses as defined in the pooling and servicing
        agreement as of the remittance date must not exceed a specified
        percentage of the cut-off date pool principal balance, depending on
        the year in which the remittance date occurs;     
       
    (4) the current realized loss ratio as defined in the pooling and
        servicing agreement as of the remittance date must not exceed 2.75%;
        and     
       
    (5) the sum of the Class M-2 principal balance and the Class B principal
        balance divided by the pool scheduled principal balance as of the
        immediately preceding remittance date must be equal to or greater
        than   %.     
   
      After payment of all principal then distributable on the Class M-2
certificates, any Class M-2 liquidation loss interest amount that has accrued
and has not previously been paid will be distributed, together with interest on
that amount at the Class M-2 remittance rate to the extent legally permissible,

Class B-1 Principal
   
      Holders of the Class B-1 certificates will be entitled to receive a
payment of principal on each remittance date on which the Class A principal
balance, the Class M-1 principal balance and the Class M-2 principal balance
have been reduced to zero or the Class B distribution test is satisfied. The
amount of principal paid on the Class B-1 certificates on any remittance date
will be the Class B Percentage of the Formula Principal Distribution Amount,

certificate account on the date remaining after payment of interest on the
Class A principal balance, the Class M-1 adjusted principal balance, the Class
M-2 adjusted principal balance and the Class B-1 adjusted principal balance and
the payment of principal due on the Class A, Class M-1 and Class M-2
certificates.     
         
      The "Class B Percentage" for any remittance date will equal:     
       
    (1) zero, if the Class A principal balance, the Class M-1 principal
        balance and the Class M-2 principal balance have not yet been
        reduced to zero and the Class B distribution test is not satisfied
        or     
       
    (2) a fraction, expressed as a percentage, the numerator of which is the
        Class B principal balance as of the remittance date, and the
        denominator of which is, as of the remittance date, the sum of:     
                
             (a) any Class A principal balance,

             (d) the Class B principal balance.     
   
      The Class B distribution test will be satisfied if each of the following
tests is satisfied:     
       
    (1) the remittance date occurs in or after    ;     
       
    (2) the average sixty-day delinquency ratio test as defined in the
        pooling and servicing agreement as of the remittance date must not
        exceed 4.50%;     
       
    (3) the cumulative realized losses as defined in the pooling and
        servicing agreement as of the remittance date must not exceed a
        specified percentage of the cut-off date pool principal balance,
        depending on the year in which the remittance date occurs:     
       
    (4) the current realized loss ratio as defined in the pooling and
        servicing agreement as of the remittance date must not exceed 2.75%;
               
    (5) the class B principal balance divided by the pool scheduled
        principal balance as of the immediately preceding remittance date
        must be equal to or greater than 12.00%; and     
       
    (6) the Class B principal balance must not be less than $    .     
   
      After payment of all principal then distributable on the Class B-1
certificates, any Class B-1 liquidation loss interest amount that has accrued
and has not previously been paid will be distributed, together with interest on
that amount at the Class B-1 remittance rate to the extent legally permissible,
to the extent of the remaining amount available.     
 
Class B-2 Interest
   
      Interest will be paid to the Class B-2 certificateholders on each
remittance date, to the extent of any remaining amount available, and any
amount paid under the limited

guarantee. Interest on the outstanding Class B-2 principal balance will accrue
from      , 1999, or from the most recent remittance date on which interest has
been paid, to but excluding the following remittance date. The Class B-2
principal balance is the original Class B-2 principal balance less the sum of
all amounts previously distributed to Class B-2 certificateholders on account
of principal. If, on a particular remittance date, the remaining amount
available in the certificate account is not sufficient to make a full
distribution of interest to the Class B-2 certificateholders and Green Tree
fails to pay the amount under the limited guarantee, the amount of the
deficiency will be carried forward and added to the amount the holders will be
entitled to receive on the next remittance date. Any amount carried forward
will bear interest at the Class B-2 remittance rate, to the extent permitted by
law.     
   
      The Class B-2 remittance rate on each remittance date will be   % per
year, subject to a maximum rate equal to the weighted average of the contract
rates on the contracts in the contract pool, computed on the basis of a 360-day
year of twelve 30-day months. In all but the most unusual prepayment scenarios,
we anticipate that the Class B-2 remittance rate will be   %. In the unlikely
event that a large number of contracts having contract rates higher than   %
were to prepay while the contracts having contract rates equal to or lower than
  % did not prepay, with the result that the interest collections on the
remaining contracts were not sufficient to support a Class B-2 remittance rate
of   %, then the Class B-2 remittance rate would be equal to the weighted
average of the contract rates on the contracts remaining in the contract pool.
Of the initial contracts,   % by aggregate principal balance as of the cut-off
date had contract rates higher than   %. The weighted average of the contract
rates on the initial contracts as of the cut-off date was approximately   %.
    
Class B-2 Principal
   
      Except for payments of the Class B-2 liquidation loss amount, as
described below under "--Losses on Liquidated Contracts", the Class B-2
certificateholders will be entitled to receive principal only on remittance
dates on which:     
       
    .  the Class B-1 principal balance has been reduced to zero, which we
       refer to as the "Class B-1 cross-over date" and     
       
    .  the Class B distribution test is satisfied; provided, however, that
       if the Class A principal balance, the Class M-1 principal balance,
       the Class M-2 principal balance and the Class B-1 principal balance
       have been reduced to zero, the Class B-2 certificateholders will
       still be entitled to receive principal.     
   
      On each remittance date on or after the Class B-1 cross-over date on
which each Class B distribution test is satisfied, the Class B Percentage of
the Formula Principal Distribution Amount will be distributed, to the extent of
the remaining amount available after payment of interest on the Class B-2
certificates, to the Class B-2 certificateholders until the Class B-2 principal

      The "Class B Percentage" for any remittance date will equal:     
       
    (1) zero, if the Class A principal balance, the Class M-1 principal
        balance and the Class M-2 principal balance have not yet been
        reduced to zero and the Class B distribution test is not satisfied
        or     
       
    (2) a fraction, expressed as a percentage, the numerator of which is the
        Class B principal balance as of the remittance date, and the
        denominator of which is, as the remittance date, the sum of:     
                
             (a) any Class A principal balance,     
                
             (b) any Class M-1 principal balance,     
                
             (c) any Class M-2 principal balance, and     
                
             (d) any Class B principal balance.     
 
Subordination of Class M-1 Certificates, Class M-2 Certificates, Class B
Certificates, Class B-3I Certificates and Class C Certificates
   
      The rights of the holders of the Class M-1 certificates, the Class M-2
certificates, the Class B certificates, the Class B-3I certificates and the
Class C certificates to receive distributions on the contracts in the trust
will be subordinated to the rights of the Class A certificateholders, as
described in this section. This subordination is intended to enhance the
likelihood of regular receipt by the holders of the Class A certificates of the
full amount of their scheduled monthly payments of principal and interest and
to afford these holders protection against losses on liquidated contracts. The
protection afforded to the Class A certificateholders by means of the
subordination feature will be accomplished by the preferential right of the
Class A certificateholders to receive on any remittance date the amount of
interest due on the Class A certificates, including any interest due on a prior
remittance date but not received, prior to any distribution being made on a
remittance date in respect of interest on the Class M-1 certificates, the Class
M-2 certificates, the Class B certificates and the Class B-3I certificates.
Thereafter, any remaining amount available in the certificate account will be
applied to the payment of interest due on the Class M-1 certificates, then to
the Class M-2 certificates, and then to the payment of interest due on the
Class B-1 certificates.     
   
      After payment of all interest due on the Class A principal balance, the
Class M-1 adjusted principal balance, the Class M-2 adjusted principal balance
and the Class B-1 adjusted principal balance, any remaining amount available
will be distributed in the following order of priority:     
       
    (1) first, the Class A Percentage of the Formula Principal Distribution
        Amount will be distributed to the Class A certificateholders;     
       
    (2) then, if the remaining amount available is sufficient, the Class M-1
        Percentage of the Formula Principal Distribution Amount plus any
        unpaid Class M-1 liquidation loss interest amount will be
        distributed to the Class M-1 certificateholders;     
 
                                      S-56
<PAGE>
 
       
    (3) then, if the remaining amount available is sufficient, the Class M-2
        Percentage of the Formula Principal Distribution Amount plus any
        unpaid Class M-2 liquidation loss interest amount will be
        distributed to the Class M-2 certificateholders;     
   
      (4)then, the remaining amount available is sufficient, the Class B
Percentage of the Formula Principal Distribution Amount plus any unpaid Class
B-1 liquidation loss interest amount will be distributed to the Class B-1
certificateholders.     
   
After distribution of all interest and principal then payable on the Class A,
Class M-1, Class M-2 and Class B-1 certificates, the Class B-2
certificateholders will be entitled to distribution of all interest and
principal then payable on the Class B-2 certificates.     
   
      In addition, the rights of the holders of the Class B-2 certificates, the
Class B-3I certificates and the Class C certificates to receive distributions
will be subordinate to the rights of the Class B-1 certificateholders. This
subordination is intended to enhance the likelihood of regular receipt by the
holders of the Class B-1 certificates of the full amount of their scheduled
monthly payments of principal and interest and to afford the holders protection
against losses on liquidated contracts. The protection afforded to the Class B-
1 certificateholders by means of the subordination feature will be accomplished
by the preferential right of the Class B-1 certificateholders to receive, prior
to any distribution being made on a remittance date on the Class B-2
certificates, the Class B-3I certificates and the Class certificates, the
amount of principal and interest due them on each remittance date out of the
remaining amount available on deposit on that date in the certificate account
and by the right of the Class B-1 certificateholders to receive future
distributions on the contracts that would otherwise be payable to the holders
of Class B-2 certificates.     
   
      The rights of the Class B-3I and Class C certificateholders to receive
distributions will be subordinated to the rights of the Class B-2
certificateholders. On each remittance date the Class B-3I certificateholders
will receive any remaining amount available, after payment of the amount
distributed to the Class A, Class M-1, Class M-2, Class B-1 and Class B-2
certificateholders as described above, less the monthly servicing fee and
amounts retained by the servicer to reimburse itself for taxes paid for
prohibited transactions, but in no event greater than the excess interest, as
defined in the pooling and servicing agreement. On each remittance date, the
Class C subsidiary certificateholders will be entitled to receive any portion
of the remaining amount available, after payment of all amounts described
above, attributable to aggregate repossession profits, as defined in the
pooling and servicing agreement.     
   
      As described above, before the Class A principal balance is reduced to
zero, the distribution of principal to the Class A certificateholders on any
remittance date is intended to include the Class A percentage of the scheduled
principal balance of each contract that became a liquidated contract during the
related due period. If the liquidation proceeds, net of related liquidation
expenses, from the liquidated contract are less than its scheduled principal
balance plus accrued interest, the deficiency will, in effect, be absorbed by
the Class M-1, Class M-2, Class B, Class B-3I and Class C certificateholders
and Green Tree, since a portion of the amount available equal to that     
 
                                      S-57
<PAGE>
 
   
deficiency and otherwise distributable to them will be paid to the Class A
certificateholders. If the amount available is not sufficient to cover the
entire amount distributable to the Class A certificateholders, the Class M-1
certificateholders or the Class M-2 certificateholders on a particular
remittance date, then the amount distributable to the Class A
certificateholders, the Class M-1 certificateholders or the Class M-2
certificateholders, as applicable, will be increased on future remittance dates
by the amount of that deficiency plus the applicable interest on that amount.
To the extent such deficiency is not covered by future collections or is not
absorbed by the Class B-3I certificateholders or the monthly servicing fee, so
long as Green Tree is the servicer), the Class B certificateholders will absorb
these deficiencies. If the amount available is sufficient to cover the
amounts distributable on principal to the Class A certificateholders, the Class
M-1 certificateholders or Class M-2 certificateholders but is not sufficient to
cover any amounts distributable on principal to the Class B-1
certificateholders on a particular remittance date, the amount of the
deficiency will be carried forward as an amount that the Class B-1
certificateholders are entitled to receive on the next remittance date.
Consequently, but for the effect of the relative subordination of the monthly
servicing fee payable to the servicer so long as Green Tree is the servicer and
amounts otherwise distributable to the Class B-2, Class B-3I and Class C
certificateholders, the Class B-1 certificateholders will absorb:     
       
    .  all losses on each liquidated contract in the amount by which its
       liquidation proceeds, net of the related liquidation expenses, are
       less than its unpaid principal balance plus accrued and unpaid
       interest less the monthly servicing fee; and     
       
    .  all delinquent payments on the contracts.     
   
But for the effect of the relative subordination of the monthly servicing fee
payable to the servicer so long as Green Tree is the servicer and amounts
otherwise distributable to the Class B-3I and the Class C certificateholders on
each remittance date, and amounts paid under the limited guarantee, the Class
B-2 certificateholders will absorb:     
       
    .  all losses on each liquidated contract in the amount by which its
       liquidation proceeds, net of the related liquidation expenses, are
       less than its unpaid principal balance plus accrued and unpaid
       interest less the monthly servicing fee; and     
       
    .  all delinquent payments on the contracts.     
   
Class B-2 Certificateholders, however, will be entitled to receive guarantee
payments and amounts otherwise distributable on remittance dates as:     
       
    .  the Class B-3I distribution amount; and     
       
    .  the monthly servicing fee payable to the servicer, (so long as Green
       Tree is the servicer), and would be entitled to receive any amounts,
       not received by the Class B-2 certificateholders on a prior
       remittance date.     
   
If Green Tree fails to make a payment required under the limited guarantee, the
Class B-2 certificateholders will incur a loss on their investment in the Class
B-2 certificates.

Losses on Liquidated Contracts
   
      If the amount available in the certificate account for any remittance
date is insufficient to distribute the full formula principal distribution
amount for that remittance date to the certificateholders, the aggregate
outstanding principal balance of the certificates will be greater than the pool
scheduled principal balance for that remittance date. If this occurs, the
amount of the deficiency, which we refer to as the "liquidation loss amount,"
would be allocated first to the Class B-2 certificates, and Green Tree would be
obligated to pay the amount of the Class B-2 liquidation loss amount to the
Class B-2 certificateholders under the limited guarantee. If on any remittance
date the sum of the Class A principal balance, the Class M-1 principal balance,
the Class M-2 principal balance and the Class B-1 principal balance equal the
pool scheduled principal balance, no further liquidation loss amounts could be
allocated to the Class B-2 certificates and any further liquidation loss
amounts realized would be allocated to reduce the Class B-1 adjusted principal
balance. If the Class B-1 adjusted principal balance were reduced to zero, any
further liquidation loss amounts realized would be allocated to reduce the
Class M-2 adjusted principal balance. If the Class M-2 adjusted principal
balance were reduced to zero, any further liquidation loss amounts realized
would be allocated to the Class M-1 adjusted principal balance. Any liquidation
loss amounts would be reduced on subsequent remittance dates to the extent that
the amount available in the certificate account on the remittance dates is
sufficient to permit the distribution of principal due on the certificates on
prior remittance dates but not paid. If the adjusted principal balance of a
class of certificates were reduced by a liquidation loss amount, interest
accruing on that class other than the Class B-2 certificates would be
calculated on the adjusted principal balance of that class. The interest
accruing on that class's liquidation loss amount each month, plus interest at
the applicable certificate rate on any liquidation loss interest amount due on
a prior remittance date but not paid, would be paid to the certificateholders
of that class from the amount available after distribution of principal on that
class but prior to any distribution of principal on a subordinate class.     
 
Capitalized Interest Account
   
      Because payments received with respect to interest on the contracts may
be insufficient to cover payments of interest on the certificates on the
remittance dates in       and       1999, a capitalized interest account will
be established on the closing date with a deposit of an amount approved by the
rating agencies. Funds on deposit in the capitalized interest account will be
invested in eligible investments, as described under "--Payments on Contracts;
Distributions on Certificates". If the amount available is insufficient to make
a full distribution of interest on the certificates, other than the Class B-2
certificates, on the remittance dates in       and       1999, the trustee will
withdraw the amount of any shortfall from the capitalized interest account and
deposit that amount in the certificate account. Green Tree will be obligated
under the limited guarantee to make a guarantee payment equal to any shortfall
in the amount distributable on the Class B-2 certificates, as described below
under "--Limited Guarantee of Green Tree." The capitalized interest account
will be part of the trust but not part of the Master REMIC or the Subsidiary
REMIC.     
 
                                      S-59
<PAGE>
 
   
Any funds remaining on deposit in the capitalized interest account after the
distribution to certificateholders in       1999 will be released to a
subsidiary of Green Tree.     
   
Limited Guarantee of Green Tree     
   
      To mitigate the effect of the subordination of the Class B-2 certificates
and liquidation losses and delinquencies on the contracts, Green Tree will
provide a limited guarantee against losses that would otherwise be absorbed by
the Class B-2 certificates. Each payment required to be made under the limited
guarantee is referred to as a "guarantee payment." Before the Class B-1 cross-
over date, or on any remittance date on or after the Class B-1 cross-over date
on which the Class B distribution test is not satisfied unless the Class A
principal balance, the Class M-1 principal balance and the Class M-2 principal
balance have been reduced to zero, the guarantee payment will equal any amount,
by which:     
       
    (1) the Class B-2 Formula Distribution Amount for that remittance date
        which will be equal to accrued and unpaid interest on the Class B-2
        certificates for that remittance date plus any Class B-2 liquidation
        loss amount for that remittance date, exceeds     
       
    (2) the Class B-2 distribution amount for that remittance date.     
   
The Class B-2 liquidation loss amount for any remittance date equals any
amount, by which the sum of the Class A principal balance, the Class M-1
principal balance, the Class M-2 principal balance, the Class B-1 principal
balance and the Class B-2 principal balance for that remittance date exceeds
the pool scheduled principal balance for that remittance date. On each
remittance date on or after the Class B-1 cross-over date, if the Class B
distribution test is satisfied on that remittance date, or if the Class A
principal balance, the Class M-1 principal balance and the Class M-2 principal
balance have been reduced to zero, the guarantee payment will equal any amount,
by which:     
       
    (1) the Class B-2 Formula Distribution Amount for that remittance date,
        which will include both interest and principal and any Class B-2
        liquidation loss amount exceeds:     
       
    (2) the remaining amount available for that remittance date.     
   
      The limited guarantee will be an unsecured general obligation of Green
Tree and will not be supported by any letter of credit or other credit
enhancement arrangement. The limited guarantee will not benefit in any way, or
result in any payment to, the Class A, Class M-1, Class M-2, Class B-1, Class
B-3I or Class C certificateholders. The ratings assigned to the Class B-2
certificates may be affected by the ratings of Green Tree's debt securities.

Repurchase Option
   
      The pooling and servicing agreement provides that on any remittance date
on which the pool scheduled principal balance is less than 10% of the cut-off
date pool principal balance, Green Tree or the servicer will have the option to
repurchase, upon Green Tree or the servicer giving notice mailed no earlier
than the first day and no later than the 10th day of the month next preceding
the month of the final distribution, all outstanding contracts at a price equal
to the greater of:     
       
    (1) the sum of:     
                
             (a) 100% of the scheduled principal balance of each contract,
                 other than any contract as to which the related manufactured
                 home has been repossessed and whose fair market value is
                 included to clause below as of the final remittance date, and
                        
             (b) the fair market value of any acquired property, as determined
                 by Green Tree; and     
       
    (2) the aggregate fair market value, as determined by Green Tree of all
        of the assets of the trust, plus, in each case, any unpaid interest
        at the applicable Class A remittance rate on each class of Class A
        certificates, any unpaid interest at the Class M-1 remittance rate
        on the Class M-1 certificates, any unpaid interest at the Class M-2
        remittance rate on the Class M-2 certificates, and any unpaid
        interest at the related remittance rates on each class of Class B
        certificates, as well as one month's interest at the applicable
        contract rate on the scheduled principal balance of each contract,
        including any contract as to which the related manufactured home has
        been repossessed. (Section 8.05.)     
   
Termination of the Pooling and Servicing Agreement     
   
      The pooling and servicing agreement will terminate upon the last action
required to be taken by the trustee on the final remittance date following the
later of:     
       
    (1) the purchase by Green Tree or the servicer of all contracts and all
        property acquired in respect of any contract remaining in the trust
        as described under "--Repurchase Option," or:     
       
    (2) the final payment or other liquidation of the last contract
        remaining in the trust or the disposition of all property acquired
        upon repossession of any manufactured home.     
   
      Upon presentation and surrender of the certificates, the trustee shall
cause to be distributed, in the following order of priority, to
certificateholders on the final remittance date in proportion to their
respective percentage interests an amount equal to:     
       
    (1)any unpaid interest on any class of Class A certificates,     
       
    (2)any unpaid interest on the Class M-1 certificates,     
       
    (3)any unpaid interest on the Class M-2 certificates,     
 
 
                                      S-66
<PAGE>
 
       
    (4)any unpaid interest on the Class B-1 certificates,     
       
    (5)the principal balance of each class of Class A certificates,     
       
    (6)the Class M-1 principal balance,     
       
    (7)the Class M-2 principal balance,     
       
    (8)the Class B-1 principal balance,     
       
    (9)any unpaid interest on the Class B-2 certificates,     
       
    (10)the Class B-2 principal balance,     
       
    (11)any unpaid interest on the Class B-3I certificates and,     
       
    (12) as to the Class C certificates, the amount which remains on deposit
         in the certificate account, other than amounts retained to meet
         claims, after application under clauses (1)-(11) above. (Section
         12.03.)     
 
Amendment
   
      The pooling and servicing agreement may be amended by agreement of the
trustee, Green Tree and the servicer at any time, without the consent of the
certificateholders, to correct manifest error, to cure any ambiguity, to
correct or supplement any provision which may be inconsistent with any other
provision, to add or amend any provision as required by S&P, Fitch or any other
nationally recognized statistical rating organization in order to improve or
maintain the rating of any class of Class A certificates, the Class M-1
certificates, the Class M-2 certificates or any class of Class B certificates
or to add other provisions not inconsistent with the agreement upon receipt of
an opinion of counsel to the servicer that the amendment will not adversely
affect in any material respect the interests of any certificateholder. (Section
12.07.) Neither Green Tree nor the servicer is obligated to take any action to
maintain or improve the rating given any class of Class A certificates, the
Class M-1 certificates, the Class M-2 certificates or any class of Class B
certificates.     
   
      The pooling and servicing agreement may also be amended from time to time
by the trustee, Green Tree and the servicer, with the consent of the holders of
certificates of each class affected evidencing, as to each class, percentage
interests aggregating at least 51%, provided that no amendment shall:     
       
    .  reduce in any manner the amount of, or delay the timing of,
       collections of payments on contracts or distributions which are
       required to be made on any certificate without the consent of the
       holder of each certificate affected,     
       
    .  reduce these percentages of certificateholders required for any
       amendment of the agreement, without the unanimous consent of the
       certificateholders,     
       
    .  adversely affect the status of either the Subsidiary REMIC or the
       Master REMIC as a REMIC or the status of the certificates as "regular
       interests" in the REMIC, or cause any tax to be imposed on the trust,
       or     
       
    .  modify in any manner the rights of the Class C certificateholders,
       without the unanimous consent of the Class C certificateholders.
       (Section 12.07.)

<PAGE>
 
   
      The pooling and servicing agreement may also be amended from time to
time, without the consent of any certificateholders, by Green Tree, the trustee
and the servicer to modify, eliminate or add to the provisions of the
agreement:     
       
    (1) to maintain the qualification of each of the Subsidiary REMIC and
        the Master REMIC as a REMIC under the Code or avoid, or reduce the
        risk of, the imposition of any tax on the trust under the Code that
        would be a claim against the trust assets, provided that:     
                
             (a) an opinion of counsel is delivered to trustee to the effect
                 that the action is necessary to maintain the qualification or
                 avoid a tax or reduce the risk of its imposition and:     
                
             (b) the amendment shall not materially adversely affect the
                 interests of any certificateholder or:     
       
    (2) to prevent the trust from entering into any "prohibited transaction"
       as defined in Section 860F of the Code.     
   
      The trustee is required under the agreement to furnish certificateholders
affected with notice promptly upon execution of any amendment to the agreement.
(Section 12.07.)     
 
The Trustee
   
      [Trustee] is a national banking association, the corporate trust offices
of which are located at [address].     
   
      The pooling and servicing agreement requires the trustee to maintain, at
its own expense, an office or agency in St. Paul, Minnesota, where certificates
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the trustee and the certificate registrar and transfer
agent for the certificates under the agreement may be served. On the date of
this prospectus supplement, the address of the trustee for these purposes is
[trustee/address]. The trustee will promptly give written notice to the
certificateholders of any change in address. (Section 12.02.)     
 
Registration of the Certificates
   
      The certificates will initially be registered in the name of Cede & Co.,
the nominee of The Depository Trust Company. DTC is a limited-purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code and a "clearing agency" registered under the
provisions of Section 17A of the 1934 Act. DTC accepts securities for deposit
from its participating organizations and facilitates the clearance and
settlement of securities transactions between participants in the securities
through electronic book-entry changes in accounts of participants, eliminating
the need for physical movement of certificates. Participants include securities
brokers and dealers, banks and trust companies and clearing corporations and
may include other organizations. Indirect access to the DTC system is also
available to others such as banks, brokers, dealers and trust companies that
clear     
 
                                      S-68
<PAGE>
 
   
through or maintain a custodial relationship with a participant, either
directly or indirectly.     
   
      Certificate owners who are not participants but desire to purchase, sell
or otherwise transfer ownership of the offered certificates may do so only
through participants, unless and until definitive Class A, Class M-1, Class M-2
and Class B certificates, as defined in the paragraph below, are issued. In
addition, certificate owners will receive all distributions of principal of,
and interest on, the certificates from the trustee through DTC and
participants. Certificate owners will not receive or be entitled to receive
certificates representing their respective interests in the Class A, Class M-1,
Class M-2 and Class B certificates, except under the limited circumstances
described below.     
   
      Unless and until definitive Class A, Class M-1, Class M-2 and Class B
certificates are issued, it is anticipated that the only "certificateholder" of
the Class A, Class M-1, Class M-2 and Class B certificates will be Cede & Co.,
as nominee of DTC. Certificate owners will not be certificateholders as that
term is used in the pooling and servicing agreement. Certificate owners are
only permitted to exercise the rights of certificateholders indirectly through
participants and DTC.     
   
      While the Class A, Class M-1, Class M-2 and Class B certificates are
outstanding, except under the circumstances described in the paragraph below,
under the rules, regulations and procedures creating and affecting DTC and its
operations, DTC is required to make book-entry transfers among participants on
whose behalf it acts with respect to the Class A, Class M-1, Class M-2 and
Class B certificates and is required to receive and transmit distributions of
principal of, and interest on, the Class A, Class M-1, Class M-2 and Class B
certificates. Participants with whom certificate owners have accounts for the
Class A, Class M-1, Class M-2 and Class B certificates are similarly required
to make book-entry transfers and receive and transmit distributions on behalf
of their respective certificate owners. Accordingly, although certificate
owners will not possess certificates, the DTC rules provide a mechanism by
which certificate owners will receive distributions and will be able to
transfer their interests.     
   
      Class A, Class M-1, Class M-2 and Class B certificates will be issued in
registered form to certificate owners, or their nominees, rather than to DTC.
We refer to these certificates as "definitive Class A, Class M-1, Class M-2 and
Class B certificates" only if:     
       
    (1) DTC or Green Tree advises the trustee in writing that DTC is no
        longer willing or able to discharge properly its responsibilities as
        nominee and depository for the Class A, Class M-1, Class M-2 and
        Class B certificates and Green Tree or the trustee is unable to
        locate a qualified successor, or     
       
    (2) Green Tree at its sole option advises the trustee in writing that it
        elects to terminate the book-entry system through DTC.     
   
Upon issuance of definitive Class A, Class M-1, Class M-2 and Class B
certificates to certificate owners, these certificates will be transferable
directly, and not exclusively on     
 
                                      S-69
<PAGE>
 
   
a book-entry basis, and registered holders will deal directly with the trustee
for transfers, notices and distributions.     
   
      DTC has advised Green Tree and the trustee that, unless and until
definitive Class A, Class M-1, Class M-2 and Class B certificates are issued,
DTC will take any action permitted to be taken by a certificateholder under the
pooling and servicing agreement only at the direction of one or more
participants to whose DTC accounts the Class A, Class M-1, Class M-2 and Class
B certificates are credited. DTC has advised Green Tree that DTC will take
action with respect to any percentage interests of the Class A, Class M-1,
Class M-2 and Class B certificates only at the direction of and on behalf of
the participants with respect to these Percentage Interests of the Class A,
Class M-1, Class M-2 and Class B certificates. DTC may take actions, at the
direction of the related participants, with respect to some Class A, Class M-1,
Class M-2 and Class B certificates which conflict with actions taken with
respect to other Class A, Class M-1, Class M-2 and Class B certificates.     
   
      Issuance of the Class A, Class M-1, Class M-2 and Class B certificates in
book-entry form rather than as physical certificates may adversely affect the
liquidity of the Class A, Class M-1, Class M-2 and Class B certificates in the
secondary market and the ability of certificate owners to pledge them. In
addition, since distributions on the Class A, Class M-1, Class M-2 and Class B
certificates will be made by the trustee to DTC and DTC will credit these
distributions to the accounts of its participants, which will further credit
them to the accounts of indirect participants or certificate owners,
certificate owners may experience delays in the receipt of these distributions.
       
      DTC management is aware that some computer applications, systems, and the
like for processing data that are dependent upon calendar dates, including
dates before, on, and after January 1, 2000, may encounter Year 2000 problems.
DTC has informed its participants and other members of the financial community
that it has developed and is implementing a program so that its systems, as
they relate to the timely payment of distributions, including principal and
income payments to securityholders, book-entry deliveries, and settlement of
trades within DTC continue to function appropriately. This program includes a
technical assessment and a remediation plan, each of which is complete.
Additionally, DTC's plan includes a testing phase, which is expected to be
completed within appropriate time frames.     
   
      However, DTC's ability to perform properly its services is also dependent
upon other parties, including issuers and their agents, as well as third party
vendors from whom DTC licenses software and hardware, and third party vendors
on whom DTC relies for information or the provision of services, including
telecommunication and electrical utility service providers. DTC has informed
its participants and the financial community that it is contacting, and will
continue to contact, third party vendors from whom DTC acquires services to:
       
    .  impress upon them the importance of their services being Year 2000
       compliant; and     
       
    .  determine the extent of their efforts for Year 2000 remediation and,
       as appropriate, testing of their services.

In addition, DTC is in the process of developing contingency plans as it deems
appropriate.     
   
      According to DTC, this information about DTC has been provided to its
participants and the financial community for informational purposes only and is
not intended to serve as a representation, warranty, or contract modification
of any kind.     
 
                                USE OF PROCEEDS
   
      Substantially all of the net proceeds to be received from the sale of the
certificates will be used by Green Tree for general corporate purposes,
including the purchase of the contracts, the costs of carrying the contracts
until the sale of the certificates and to pay other expenses for pooling the
contracts and issuing the certificates.

                              ERISA CONSIDERATIONS
   
      The following information supplements, and if inconsistent supersedes,
the information in the prospectus under "ERISA Considerations."     
   
      The Employee Retirement Income Security Act of 1974, and section 4975 of
the Code impose certain restrictions on employee benefit and other plans that
are subject to ERISA or to section 4975 of the Code ("Plans") and on persons
who are fiduciaries with respect to those Plans. Employee benefit plans that
are governmental plans, as defined in section 3(32) of ERISA, and some church
plans, as defined in section 3(33) of ERISA, are not subject to ERISA
requirements. Accordingly, assets of those plans may be invested in the Class A
certificates without regard to the ERISA restrictions described in this section
and in the prospectus, subject to applicable provisions of other federal and
state laws. However, any such governmental or church plan which is qualified
under section 401(a) of the Code and exempt from taxation under section 501(a)
of the Code is subject to the prohibited transaction rules provided in section
503 of the Code.     
   
      The U.S. Department of Labor has granted substantially identical
administrative exemptions to the underwriters as follows:     
       
    .  [underwriter]: Prohibited Transaction Exemption     ; Exemption
       Application No. D-    ,   Fed. Reg.       (    );     
       
    .  [underwriter]: Prohibited Transaction Exemption    ; Exemption
       Application No. D-    ,    Fed. Reg.      (    ); and     
       
    .  [underwriter]: Prohibited Transaction Exemption     ; Exemption
       Application No. D-    ,   Fed. Reg.       (    ).     
   
We refer to all of the exemptions listed above collectively as the "Exemption."
They provide an exemption from certain of the prohibited transaction rules of
ERISA and the Code with respect to the initial purchase, the holding and the
subsequent resale by Plans of certificates representing interests in asset-
backed pass-through trusts that consist of certain receivables, loans and other
obligations that meet the conditions and requirements of the Exemption. The
receivables covered by the Exemption include manufactured housing installment
sale contracts and installment loan agreements such as the manufactured housing
contracts. The Exemption will apply to the acquisition, holding, and resale of
the Class A certificates by a Plan, provided that specified conditions are met,
including those described in the paragraph below.     
          
      Among the conditions which must be satisfied for the Exemption to apply
to the Class A certificates are the following:     
       
    (1) The acquisition of the Class A certificates by a Plan is on terms,
        including the price for the Class A certificates, that are at least
        as favorable to the Plan as they would be in an arm's-length
        transaction with an unrelated party;     
       
    (2) The rights and interests evidenced by the Class A certificates
        acquired by the Plan are not subordinated to the rights and
        interests evidenced by other certificates of the trust;     
 
 
                                      S-72
<PAGE>
 
       
    (3) The Class A certificates acquired by the Plan have received a rating
        at the time of the acquisition that is in one of the three highest
        generic rating categories from any of Moody's, S&P, Fitch or Duff &
        Phelps Credit Rating Co. (the "Exemption Rating Agencies");     
       
    (4) The trustee of the Plan is not an affiliate of any member of the
        Restricted Group, as defined in the next paragraph below;     
       
    (5) The sum of all payments made to the underwriters in connection with
        the distribution of the Class A certificates represents not more
        than reasonable compensation for underwriting the Class A
        certificates. The sum of all payments made to and retained by Green
        Tree in the sale of the manufactured housing contracts to the trust
        represents not more than the fair market value of those contracts.
        The sum of all payments made to and retained by the servicer
        represents not more than reasonable compensation for the servicer's
        services under the pooling and servicing agreement and reimbursement
        of the servicer's reasonable expenses; and     
       
    (6) The Plan investing in the Class A certificates is an "accredited
        investor" as defined in Rule 501(a)(1) of Regulation D of the
        Securities and Exchange Commission under the Securities Act of 1933.
               
      On July 21, 1997, the DOL published in the Federal Register an amendment
to the Exemption, which extends exemptive relief to mortgage-backed and asset-
backed securities transactions using pre-funding accounts for trusts issuing
pass-through certificates. The amendment generally allows mortgage loans or
other secured receivables (the "Obligations") supporting payments to
certificateholders, and having a value equal to no more than 25% of the total
principal amount of the certificates being offered by the trust, to be
transferred to the trust within a 90-day or three-month pre-funding period
following the closing date, instead of requiring that all such Obligations be
either identified or transferred on or before the closing date. The relief is
available when the following conditions are met:     
       
    (1) The ratio of the amount allocated to the pre-funding account to the
        total principal amount of the certificates being offered (the "Pre-
        Funding Limit") must not exceed 25%.     
       
    (2) All Obligations transferred after the closing date (the "Additional
        Obligations") must meet the same terms and conditions for
        eligibility as the original Obligations used to create the trust,
        which terms and conditions have been approved by an Exemption Rating
        Agency.     
       
    (3) The transfer of the Additional Obligations to the trust during the
        pre-funding period must not result in the certificates to be covered
        by the Exemption receiving a lower credit rating from an Exemption
        Rating Agency upon termination of the pre-funding period than the
        rating that was obtained at the time of the initial issuance of the
        certificates by the trust.     
       
    (4) Solely as a result of the use of pre-funding period, the weighted
        average annual percentage interest rate for all of the Obligations
        in the trust at the end of the pre-funding period must not be more
        than 100 basis points lower     
 
                                      S-73
<PAGE>
 
          
       than the average interest rate for the Obligations transferred to the
       trust on the closing date.     
       
    (5) In order to insure that the characteristics of the Additional
        Obligations are substantially similar to the original Obligations
        which were transferred to the trust fund:     
         
      .  the characteristics of the Additional Obligations must be
         monitored by an insurer or other credit support provider that is
         independent of the depositor; or     
         
      .  an independent accountant retained by the depositor must provide
         the depositor with a letter (with copies provided to each
         Exemption Rating Agency rating the certificates, the related
         underwriter and the related prospectus or trustee) stating
         whether or not the characteristics of the Additional Obligations
         conform to the characteristics described in the related
         prospectus or prospectus supplement and/or pooling and servicing
         agreement. In preparing this letter, the independent accountant
         must use the same type of procedures as were applicable to the
         Obligations transferred to the trust as of the closing date.     
       
    (6) The period of pre-funding must end no later than three months or 90
        days after the closing date or earlier in certain circumstances if
        the pre-funding account falls below the minimum level specified in
        the pooling and servicing agreement or an event of default occurs.
               
    (7) Amounts transferred to any pre-funding account and/or capitalized
        interest account used in connection with the pre-funding may be
        invested only in certain permitted investments.     
       
    (8) The related prospectus or prospectus supplement must describe:     
         
      .  any pre-funding account and/or capitalized interest account used
         in connection with a pre-funding account;     
         
      .  the duration of the period of pre-funding;     
         
      .  the percentage and/or dollar amount of the Pre-Funding Limit for
         the trust; and     
         
      .  that the amounts remaining in the pre-funding account at the end
         of the pre-funding period will be remitted to certificateholders
         as repayments of principal.     
       
    (9) The related pooling and servicing agreement must describe these
        permitted investments for the pre-funding account and/or capitalized
        interest account and, if not disclosed in the related prospectus or
        prospectus supplement, the terms and conditions for eligibility of
        Additional Obligations.     
   
      Moreover, the Exemption would provide relief from certain self-
dealing/conflict of interest prohibited transactions only if, among other
requirements:     
       
    .  in the case of the acquisition of Class A certificates in connection
       with the initial issuance, at least 50% of the Class A certificates
       are acquired by     
 
                                      S-74
<PAGE>
 
          
       persons independent of the Restricted Group, as defined in the
       paragraph below;     
       
    .  the Plan's investment in Class A certificates does not exceed 25% of
       all of the Class A certificates outstanding at the time of the
       acquisition; and     
       
    .  immediately after the acquisition, no more than 25% of the assets of
       the Plan are invested in certificates representing an interest in one
       or more trusts containing assets sold or serviced by the same entity.
              
The Exemption does not apply to Plans sponsored by Green Tree, the
underwriters, the trustee, the servicer, any obligor on the contracts included
in the trust constituting more than 5% of the aggregate unamortized principal
balance of the assets in the trust or any affiliate of these parties (the
"Restricted Group").     
   
      Green Tree believes that the Exemption will apply to the acquisition and
holding of Class A certificates sold by the underwriters and by Plans and that
all conditions of the Exemption other than those within the control of the
investors have been met. In addition, as of the date of this prospectus
supplement, no obligor on the contracts included in the trust constitutes more
than 5% of the aggregate unamortized principal balance of the assets of the
trust. Any Plan fiduciary who proposes to cause a Plan to purchase Class A
certificates should consult with its own counsel about the potential
consequences under ERISA and the Code of the Plan's acquisition and ownership
of the Class A certificates. Assets of a Plan or individual retirement account
should not be invested in the Class A Certificates unless it is clear that the
assets of the trust will not be Plan assets or unless it is clear that the
Exemption or a prohibited transaction class exemption will apply and exempt all
potential prohibited transactions. See "ERISA Considerations" in the
prospectus.     
   
      Insurance companies contemplating the investment of general account
assets in the certificates should consult with their legal advisors regarding
the applicability of PTCE 95-60 and Section 401(c) of ERISA, as described under
"ERISA Considerations" in the prospectus.     
          
      No transfer of Class M-1, Class M-2 or Class B certificates will be
permitted to be made to a Plan or to any person acquiring the certificates on
behalf of or with assets of a Plan, unless the transferee, at its expense,
delivers to the trustee and Green Tree an opinion of counsel (in form
satisfactory to the trustee and Green Tree) to the effect that the purchase or
holding of a Class M-1, Class M-2 or Class B certificate by the Plan will not
result in the assets of the trust being deemed to be Plan assets and subject to
the prohibited transaction provisions of ERISA and the Code and will not
subject the trustee, Green Tree or the servicer to any obligation or liability
in addition to those undertaken in the pooling and servicing agreement.
Alternatively, an insurance company general account may, at its expense,
deliver to the trustee and Green Tree a representation that the transfer and
holding of such a certificate are exempt under Section I and Section III of
PTCE 95-60. Unless such opinion or representation is delivered, each person
acquiring a Class M-1, Class M-2 or Class B Certificate will be deemed to
represent to the trustee, Green Tree and the servicer that that person is not a
    
                                      S-75
<PAGE>
 
Plan, acting on behalf of a Plan or investing assets of a Plan subject to ERISA
or to Section 4975 of the Code.
 
                        LEGAL INVESTMENT CONSIDERATIONS
   
      After the pre-funding period has ended, the Class A certificates and the
Class M-1 certificates offered under this prospectus supplement will constitute
"mortgage related securities" under SMMEA and will be "legal investments" for
some types of institutional investors as provided in SMMEA. Because the Class
M-2 certificates and the Class B certificates will not be rated in one of the
two highest rating categories by S&P or Fitch, the Class M-2 certificates and
the Class B certificates will not constitute "mortgage related securities" for
purposes of SMMEA. Accordingly, many institutions with legal authority to
invest in more highly rated securities based on first mortgage loans may not be
legally authorized to invest in the Class M-2 certificates and the Class B
certificates.     
   
      Green Tree makes no representation as to the proper characterization of
the Class M-2 certificates and the Class B certificates for legal investment or
financial institution regulatory purposes, or as to the ability of particular
investors to purchase Class M-2 certificates or Class B certificates under
applicable legal investment restrictions. The uncertainties described in the
paragraph above, and any unfavorable future determinations concerning legal
investment or financial institution regulatory characteristics of the Class M-2
certificates and the Class B certificates, may adversely affect the liquidity
of the Class M-2 certificates and the Class B certificates.

      In the underwriting agreement, the underwriters have agreed, subject to
the terms and conditions in the agreement, to purchase all of the certificates

      Until the distribution of the certificates is completed, rules of the
Commission may limit the ability of the underwriters and selling group members
to bid for and purchase the certificates. As an exception to these rules, the
underwriters are permitted to engage in transactions that stabilize the price
of the certificates. These transactions consist of bids or purchases for the
purpose of pegging, fixing or maintaining the price of the certificates.     
   
      In general, purchases of a security for the purpose of stabilization or
to reduce a short position could cause the price of the security to be higher
than it might be without these purchases.     
   
      Neither Green Tree nor any of the underwriters makes any representation
or prediction as to the direction or magnitude of any effect that the
transactions described above may have on the prices of the certificates. In
addition, neither Green Tree nor any of the underwriters makes any
representation that the underwriters will engage in these transactions or that
these transactions, once commenced, will not be discontinued without notice.
       
      The underwriting agreement provides that Green Tree will indemnify the
underwriters against liabilities, including liabilities under the Securities
Act of 1933, or contribute to payments the underwriters may be required to
make.

PROSPECTUS
 
                       Green Tree Financial Corporation,
                              Seller and Servicer
 
            Manufactured Housing Contract Pass-Through Certificates
 
                              (Issuable In Series)
   
  We are offering certificates for manufactured housing contracts under this
prospectus and a prospectus supplement. The certificates for manufactured
housing contracts are referred to as the "certificates" and each separate
series of certificates is referred to as a "series." Green Tree Financial
Corporation will form a trust for each Series, and the trust will issue the
certificates of that series. The certificates of any series may comprise
several different classes. A trust may also issue one or more other interests
in the trust that will not be offered under this prospectus.     
   
  The right of each class of certificates within a series to receive payments
may be senior or subordinate to the rights of one or more of the other classes
of certificates. In addition, a series of certificates may include one or more
classes which on the one hand are subordinated to one or more classes of
certificates, while on the other hand are senior to one or more classes of
certificates. The rate of principal and interest payment on the certificates of
any class will depend on the priority of payment of that class and the rate and
timing of payments of the related manufactured housing contracts.     
   
  The prospectus supplement will list the remittance rate that the holders of
certificates will receive for each class in a series. The prospectus supplement
will specify whether the remittance rate will be fixed, variable or adjustable.
    
       
                                  -----------
          
  The certificates will represent obligations of the related trust and will not
represent any interest in or obligation of Green Tree Financial Corporation or
any of its affiliates, except as specified in the prospectus supplement.     
 
  Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or determined if
this prospectus is truthful or complete. Any representation to the contrary is
a criminal offense.
 
                                  -----------
   
  This prospectus may not be used to consummate sales of any certificates
unless accompanied by a prospectus supplement for that series.

General
   
    Certificates evidencing interests in pools of manufactured housing
contracts may be issued from time to time in series under a separate pooling
and servicing agreement between Green Tree, as seller and servicer, and the
trustee.     
   
    The certificates of each series may be issued in one or more classes or
subclasses as and on the terms specified in the related prospectus supplement,
each of which will evidence the interest specified in the related prospectus
supplement in the contract pool and other property held in a Trust Fund for the
benefit of the certificateholders. Each Trust Fund will include:     
     
  .  a contract pool,     
     
  .  the amounts held from time to time in a trust certificate account
     maintained by the trustee under the Agreement,     
     
  .  proceeds from hazard insurance on individual manufactured homes and
     manufactured homes, or the related real estate in the case of land-and-
     home contracts, acquired by repossession,     
     
  .  any letter of credit, guarantee, surety bond, insurance policy, cash
     reserve fund or other credit enhancement securing payment of all or
     part of a series of certificates, and     
     
  .  other property as specified in the related prospectus supplement.     
   
    Each certificate will evidence the interest specified in the related
prospectus supplement in one trust fund, containing one contract pool comprised
of contracts having the aggregate principal balance as of the close of business
on the specified day of the month of the creation of the pool (the "cut-off
date") specified in the related prospectus supplement. Holders of certificates
of a series will have interests only in that contract pool and will have no
interest in the contract pool created for any other series of certificates. If
specified in the related prospectus supplement, the trust fund may include a
pre-funding account which would be used to purchase subsequent contracts from
Green Tree during the pre-funding period specified in the related prospectus
supplement. The related prospectus supplement will specify the conditions that
must be satisfied before any transfer of subsequent contracts, including the
requisite characteristics of the subsequent contracts.     
   
    Except as otherwise specified in the related prospectus supplement, all of
the contracts will have been originated by Green Tree in the ordinary course of
its business. The following is a brief description of the contracts expected to
be included in the trust fund. Specific information respecting the contracts
will be provided in the prospectus supplement and, if not contained in the
related prospectus supplement, in a report on Form 8-K to be filed with the
Securities and Exchange Commission within fifteen days after the initial     
 
                                       3

issuance of the certificates. A copy of the pooling and servicing agreement for
each series of certificates will be attached to the Form 8-K and will be
available for inspection at the corporate trust office of the trustee specified
in the related prospectus supplement. A schedule of the contracts relating to
that series will be attached to the pooling and servicing agreement delivered
to the trustee upon delivery of the certificates.     
   
    When we use terms in this prospectus such as "contract pool," "trust fund,"
"pooling and servicing agreement" or "remittance rate," those terms
respectively apply, unless the context otherwise indicates, to one specific
contract pool, trust fund, each pooling and servicing agreement and the
remittance rate applicable to the related series of certificates.     
 
The Contract Pools
   
    Except as otherwise specified in the related prospectus supplement, each
contract pool for a series of certificates will consist of manufactured housing
installment sales contracts and installment loan agreements, which we refer to
as the "contracts," originated by Green Tree Financial Corporation on an
individual basis in the ordinary course of business. The contracts may be
conventional manufactured housing contracts or contracts insured by the Federal
Housing Administration or partially guaranteed by the Veterans Administration.
Each contract will be secured by a manufactured home, as defined in the next
paragraph below, or by a mortgage or deed of trust relating to the real estate
to which the manufactured home is deemed permanently affixed, which we refer to
as a land-and-home contract. Except as otherwise specified in the related
prospectus supplement, the contracts will be fully amortizing and will bear
interest at a fixed or variable annual percentage contract rate or at a
contract rate which steps up on a particular date or dates, known as a "step-up
rate".     
   
    Green Tree will represent that the manufactured homes securing the
contracts consist of manufactured homes within the meaning of 42 United States
Code, Section 5402(6), which defines a "manufactured home" as "a structure,
transportable in one or more sections, which in the traveling mode, is eight
body feet or more in width or forty body feet or more in length, or, when
erected on site, is three hundred twenty or more square feet, and which is
built on a permanent chassis designed to be used as a dwelling with or without
a permanent foundation when connected to the required utilities, and includes
the plumbing, heating, air-conditioning, and electrical systems contained
therein; except that such term shall include any structure which meets all the
requirements of this paragraph except the size requirements and with respect to
which the manufacturer voluntarily files a certification required by the
Secretary [of Housing and Urban Development] and complies with the standards
established under this chapter."     
   
    For each series of certificates, Green Tree will assign the contracts
constituting the contract pool to the trustee named in the related prospectus
supplement. Green Tree, as servicer, will service the contracts under the
Agreement. See "Description of the Certificates--Servicing." Unless otherwise
specified in the related prospectus supplement, the contract documents, other
than the documents for land-and-home contracts, will be held by the servicer as
custodian for the trustee. The documents relating to any land-and-home
contracts will be held for the benefit of the trustee by a custodian appointed
under a custodial agreement between the trustee and the custodian.     
 
                                       4
<PAGE>
 
   
    Each contract pool will be composed of contracts with the annual fixed or
variable weighted average contractual rates of interest or step-up rates
specified in the prospectus supplement. Unless we specify otherwise in the
related prospectus supplement, the monthly payments for contracts bearing
interest at a step-up rate will increase on the dates on which the contract
rates are stepped up. Unless we specify otherwise in the related prospectus
supplement, each registered holder of a certificate will be entitled to receive
periodic distributions, which will be monthly unless we specify otherwise in
the related prospectus supplement, of all or a portion of principal on the
underlying contracts or interest on the principal balance of the certificate at
the remittance rate, or both.     
   
    A contract pool may include "staged-funding" contracts, under which Green
Tree makes multiple disbursements to enable the obligor to finance both the
purchase of a manufactured home and the acquisition or improvement of the
related real estate. For example, Green Tree might make disbursements to enable
the obligor to purchase the real estate on which the manufactured home is to be
located, then to make improvements on the real estate, such as a driveway, well
and septic system, then to purchase and deliver the manufactured home, and then
to make final site improvements. Before the final disbursement, the obligor
pays only interest on the disbursed amount of the loan; following the final
disbursement, the obligor begins making fully amortizing payments of principal
and interest. Green Tree will represent and warrant in the related pooling and
servicing agreement that all staged-funding contracts included in a contract
pool will have been fully disbursed within 90 days after the related closing
date, and Green Tree will be obligated to repurchase on the next remittance
date any staged-funding contract that has not been fully disbursed by that
date.     
   
    The related prospectus supplement will specify for the contracts contained
in the related contract pool, the range of the dates of origination of the
contracts; the range of the contract rates and the weighted average contract
rate; the loan-to-value ratios; the minimum and maximum outstanding principal
balances as of the cut-off date and the average outstanding principal balance
as of the cut-off date; the aggregate principal balances of the contracts
included in the contract pool as of the cut-off date; the weighted average and
range of scheduled terms to maturity as of origination and as of the cut-off
date; the original maturities of the contracts and the last maturity date of
any contract; and the locations of the obligors on the contracts. If the trust
fund includes a pre-funding account, the related prospectus supplement will
specify the conditions that must be satisfied before any transfer of subsequent
contracts, including the requisite characteristics of the subsequent contracts.
       
Conveyance of Contracts     
   
    Green Tree will transfer to the trustee all right, title and interest of
Green Tree in the contracts, including all security interests and any related
mortgages or deeds of trust, all principal and interest received on the
contracts, except receipts of principal and interest due on the contracts
before the cut-off date, all rights under hazard insurance policies on the
related manufactured homes, all documents contained in the contract files and
all proceeds derived from any of the foregoing. (Section 2.01.) On behalf of
the trust, as the issuer of the     
 
                                       5
<PAGE>
 
   
related series of certificates, the trustee, concurrently with the conveyance,
will execute and deliver the certificates to the order of Green Tree. The
contracts will be as described on a list attached to the pooling and servicing
agreement. (Sections 1.02 and 2.02.) This list will include the amount of
monthly payments due on each contract as of the date of issuance of the
certificates, the contract rate on each contract and the maturity date of each
contract. This list will be available for inspection by any certificateholder
at the principal executive office of the servicer. (Sections 1.02 and 5.04.)
Before the conveyance of the contracts to the trust, Green Tree's internal
audit department will complete a review of all of the contract files, including
the certificates of title to, or other evidence of a perfected security
interest in, the manufactured homes, confirming the accuracy of the list of
contracts delivered to the trustee. Any contract discovered not to agree with
that list in a manner that is materially adverse to the interests of the
certificateholders will be repurchased by Green Tree or replaced with another
contract, or, if the discrepancy relates to the unpaid principal balance of a
contract, Green Tree may deposit cash in the separate certificate account
maintained at an eligible institution in the name of the trustee in an amount
sufficient to offset the discrepancy. If the trust fund includes a pre-funding
account, the related prospectus supplement will specify the conditions that
must be satisfied before any transfer of subsequent contracts, including the
requisite characteristics of the subsequent contracts.     
   
    The pooling and servicing agreement will designate Green Tree as custodian
to maintain possession, as the trustee's agent, of the contracts and any other
documents related to the manufactured homes, except the land-and-home contracts
and related documents. (Sections 2.03 and 4.01.) To facilitate servicing and to
save administrative costs, the documents will not be physically segregated from
other similar documents that are in Green Tree's possession. Uniform Commercial
Code financing statements will be filed in Minnesota reflecting the sale and
assignment of the contracts to the trustee, and Green Tree's accounting records
and computer systems will also reflect the sale and assignment. In addition,
the contracts will be stamped to reflect their assignment to the trustee.
However, if through fraud, negligence or otherwise, a subsequent purchaser were
able to take physical possession of the contracts without knowledge of the
assignment, the trustee's interest in the contracts could be defeated. See
"Risk Factors--Some contracts may be unenforceable." The pooling and servicing
agreement will designate the trustee or another independent custodian, as the
trustee's agent, to maintain possession of the documents relating to all land-
and-home contracts.     
          
    Except as otherwise specified in the related prospectus supplement, Green
Tree will make warranties in the pooling and servicing agreement for each
contract as of closing date, including that:     
     
  .  as of the cut-off date, or the date of origination, if later, the most
     recent scheduled payment was made or was not delinquent more than 59
     days;     
     
  .  no provision of a contract has been waived, altered or modified in any
     respect, except by instruments or documents contained in the contract
     file or the land-and-home contract file;     
 
                                       6

  .  each contract is a legal, valid and binding obligation of the obligor
     and is enforceable in accordance with its terms, except as may be
     limited by laws affecting creditors' rights generally;     
     
  .  no contract is subject to any right of rescission, set-off,
     counterclaim or defense;     
     
  .  each contract is covered by hazard insurance described under "--
     Servicing--Hazard Insurance;"     
     
  .  each contract has been originated by a manufactured housing dealer or
     Green Tree in the ordinary course of the dealer's or Green Tree's
     business and, if originated by a manufactured housing dealer, was
     purchased by Green Tree in the ordinary course of business;     
     
  .  no contract was originated in or is subject to the laws of any
     jurisdiction whose laws would make the transfer of the contract or an
     interest in the contract to the trustee under the pooling and servicing
     agreement or under the certificates unlawful;     
     
  .  each contract complies with all requirements of law;     
     
  .  no contract has been satisfied, subordinated in whole or in part or
     rescinded and the manufactured home securing the contract has not been
     released from the lien of the contract in whole or in part;     
     
  .  each contract creates a valid and enforceable first priority security
     interest in favor of Green Tree in the manufactured home covered by the
     contract and, each land-and-home contract, the lien created has been
     recorded or will be recorded within six months, and the security
     interest or lien has been assigned by Green Tree to the trustee;     
     
  .  all parties to each contract had capacity to execute the contract;     
     
  .  no contract has been sold, assigned or pledged to any other person and
     before the transfer of the contracts by Green Tree to the trustee,
     Green Tree had good and marketable title to each contract free and
     clear of any encumbrance, equity, loan, pledge, charge, claim or
     security interest, and was the sole owner and had full right to
     transfer the contract to the trustee;     
     
  .  as of the cut-off date, or the date of origination, if later, there was
     no default, breach, violation or event permitting acceleration under
     any contract except for payment delinquencies permitted by the first
     clause above, no event which with notice and the expiration of any
     grace or cure period would constitute a default, breach, violation or
     event permitting acceleration under the contract, and Green Tree has
     not waived any of the foregoing;     
     
  .  as of the closing date there were, to the best of Green Tree's
     knowledge, no liens or claims which have been filed for work, labor or
     materials affecting a manufactured home or any related mortgaged
     property securing a contract, which are or may be liens prior or equal
     to the lien of the contract;

  .  each contract other than a step-up rate contract is a fully-amortizing
     loan with a fixed contract rate and provides for level payments over
     the term of the contract;     
     
  .  each contract contains customary and enforceable provisions which
     render the rights and remedies of the holder adequate for realization
     against the collateral of the benefits of the security;     
     
  .  the description of each contract appearing in the list delivered to the
     trustee is true and correct;     
     
  .  there is only one original of each contract;     
     
  .  except as specified in the related prospectus supplement, none of the
     contracts had a loan-to-value ratio at origination greater than 95%
     and, if the related manufactured home was new at the time the contract
     was originated, the original principal balance of the contract did not
     exceed 130% of the manufacturer's invoice price plus 100% of taxes and
     license fees, 130% of freight charges, 100% of the dealer's cost of
     dealer-installed equipment (not to exceed 25% of the amount financed in
     all states except California; not to exceed 70% of the manufacturer's
     invoice price in California if required to meet park requirements) and
     up to $1,500 of set-up costs per module;     
     
  .  at the time of origination of each contract the obligor was the primary
     resident of the related manufactured home;     
     
  .  other than the land-and-home contracts, the related manufactured home
     is not considered or classified as part of the real estate on which it
     is located under the laws of the jurisdiction in which it is located,
     and as of the closing date the manufactured home was, to the best of
     Green Tree's knowledge, free of damage and in good repair;     
     
  .  the related manufactured home is a "manufactured home" within the
     meaning of 42 United States Code, Section 5402(6) and each manufactured
     housing dealer from whom Green Tree purchased a contract was approved
     by Green Tree in accordance with the requirements of the Secretary of
     Housing and Urban Development;     
     
  .  each contract is a "qualified mortgage" under Section 860G(a)(3) of the
     Code and each manufactured home is "manufactured housing" within the
     meaning of Section 25(e)(10) of the Code; and     
     
  .  if a contract is an FHA/VA contract, the contract has been serviced in
     accordance with FHA/VA regulations, the insurance or guarantee of the
     contract under the FHA/VA regulations and related laws is in full force
     and effect, and no event has occurred which, with or without notice or
     lapse of time or both, would impair the insurance or guarantee.     
   
    Under the terms of the pooling and servicing agreement, and subject to the
conditions specified in the preceding paragraph and to Green Tree's option to
effect a substitution as described in the next paragraph, Green Tree will be
obligated to repurchase for the Repurchase Price (as defined below in this
paragraph) any contract on the first business day     
 
                                       8
<PAGE>
 
   
after the first Determination Date (as defined below under "--Distributions on
Certificates") which is more than 90 days after Green Tree becomes aware, or
should have become aware, or Green Tree's receipt of written notice from the
trustee or the servicer, of a breach of any representation or warranty of Green
Tree in the pooling and servicing agreement that materially adversely affects
the trust's interest in any contract if the breach has not been cured. (Section
3.05.) The Repurchase Price for any contract will be the remaining principal
amount outstanding on the contract on the date of repurchase plus accrued and
unpaid interest at its contract rate to the date of the repurchase. (Section
1.02.) This repurchase obligation constitutes the sole remedy available to the
Trust Fund and the certificateholders for a breach of a warranty under the
pooling and servicing agreement with respect to the contracts, but not for any
other breach by Green Tree of its obligations under the pooling and servicing
agreement. If a prohibited transaction tax under the REMIC provisions of the
Code is incurred for the repurchase, distributions otherwise payable to
residual certificateholders will be applied to pay the tax. Green Tree will be
required to pay the amount of the tax that is not funded out of the
distributions. (Section 6.06.)     
   
    In lieu of purchasing a contract as specified in the preceding paragraph,
during the two-year period following the closing date, Green Tree may, at its
option, substitute an Eligible Substitute Contract (as defined in the next
sentence) for the contract that it is otherwise obligated to repurchase, which
we refer to in this prospectus as the "Replaced Contract." An Eligible
Substitute Contract is a contract that satisfies, as of the date of its
substitution, the representations and warranties specified in Article III of
the pooling and servicing agreement, has a scheduled principal balance that is
not greater than the scheduled principal balance of the Replaced Contract, has
a contract rate that is at least equal to the contract rate of the Replaced
Contract and has a remaining term to scheduled maturity that is not greater
than the remaining term to scheduled maturity of the Replaced Contract.
(Section 1.02.)
       
Green Tree will be required to deposit in the certificate account cash in the
amount by which the scheduled principal balance of the Replaced Contract
exceeds the scheduled principal balance of the contract being substituted. This
deposit will be deemed to be a partial principal prepayment. (Sections 1.02 and
3.05.)     
   
Payments on Contracts     
   
    Each certificate account will be a trust account established by the
servicer as to each series of certificates in the name of the trustee:     
     
  (1) with a depository institution, the long-term unsecured debt
      obligations of which at the time of any deposit are rated within the
      two highest rating categories or the other rating category as will not
      adversely affect the ratings assigned to the certificates by each
      rating agency rating the certificates of that series; or     
     
  (2) with the trust department of a national bank; or     
     
  (3) in an account or accounts the deposits in which are fully insured by
      the FDIC; or     
     
  (4) in an account or accounts the deposits in which are insured by the
      FDIC to the limits established by the FDIC, the uninsured deposits in
      which are otherwise     
 
                                       9
<PAGE>
 
        
     secured so that, as evidenced by an opinion of counsel, the
     certificateholders have a claim or the funds in the certificate account
     or a perfected first priority security interest against any collateral
     securing the funds that is superior to the claims of any other
     depositors or general creditors of the depository institution with
     which the certificate account is maintained; or     
     
  (5) otherwise acceptable to the rating agency without reduction or
     withdrawal of the rating assigned to the relevant certificates.     
   
The collateral eligible to secure amounts in the certificate account is
limited to United States government securities and other high-quality
investments specified in the applicable agreement ("Eligible Investments"). A
certificate account may be maintained as an interest bearing account, or the
funds held in the account may be invested pending each succeeding remittance
date in Eligible Investments.     
   
    Unless otherwise specified in the related prospectus supplement, the
servicer will deposit in the certificate account on a daily basis the
following payments and collections received or made by it subsequent to the
cut-off date, including scheduled payments of principal and interest due after
the cut-off date but received by the servicer on or before the cut-off date:
       
  .  all obligor payments on account of principal, including principal
     prepayments, on the contracts;     
     
  .  all obligor payments on account of interest on the contracts;     
     
  .  all amounts received and retained for the liquidation of defaulted
     contracts, net of liquidation expenses ("Net Liquidation Proceeds");
            
  .  all proceeds received under any hazard or other insurance policy
     covering any contract, other than proceeds to be applied to the
     restoration or repair of the manufactured home or released to the
     obligor;     
     
  .  any Advances made as described under "Advances" and other amounts
     required under the pooling and servicing agreement to be deposited in
     the certificate account;     
     
  .  all amounts received from any credit enhancement provided on a series
     of certificates; and     
     
  .  all proceeds of any contract or property acquired in respect thereof
     repurchased by the servicer, or Green Tree, or otherwise as described
     above or under "--Termination of the Agreement" below.

                                USE OF PROCEEDS
   
    Unless we specify otherwise in the applicable prospectus supplement,
substantially all of the net proceeds to be received from the sale of each
series of certificates will be used by Green Tree for general corporate
purposes, including the purchase of the contracts, costs of carrying the
contracts until sale of the related certificates and to pay other expenses
connected with pooling the contracts and issuing the certificates.     
 
                        GREEN TREE FINANCIAL CORPORATION
 
General
   
    Green Tree is a Delaware corporation which, as of December 31, 1998, had
stockholders' equity of approximately $2.2 billion. Green Tree purchases,
pools, sells and services conditional sales contracts for manufactured housing
throughout the nation. Green Tree is the largest servicer of manufactured
housing government insured or guaranteed contracts and of conventional
manufactured housing contracts in the United States. Green Tree acts as
servicer of the contracts. Servicing functions are performed through Green Tree
Financial Servicing Corporation, a wholly owned subsidiary of Green Tree.
Through its principal offices in Saint Paul, Minnesota and service centers
throughout the United States, Green Tree serves all 50 states. Green Tree's
principal executive offices are located at 1100 Landmark Towers, 345 St. Peter
Street, St. Paul, Minnesota 55102-1639 (telephone (651) 293-3400). Green Tree's
Annual Report on Form 10-K for the year ended December 31, 1998, most recent
proxy statement and, when available, subsequent quarterly and annual reports
are available from Green Tree upon written request.     
 
Contract Origination
   
    Through its regional service centers, Green Tree arranges to purchase
manufactured housing contracts from manufactured housing dealers located
throughout the United States. Green Tree's regional service center personnel
contact dealers located in their region and explain Green Tree's available
financing plans, terms, prevailing rates and credit and financing policies. If
the dealer wishes to use Green Tree's available customer financing, the dealer
must make
an application for dealer approval. Upon satisfactory results of Green Tree's
 investigation of the dealer's creditworthiness and general business
reputation, Green Tree and the dealer execute a dealer agreement. Green Tree
also originates manufactured housing installment loan agreements directly with
customers, particularly in instances where a homeowner wants to refinance an
existing manufactured housing contract, which may or may not be with Green
Tree.     
   
    All contracts that Green Tree originates are written on forms provided by
Green Tree and are originated on an individually approved basis in accordance
with Green Tree's guidelines. The dealer or the customer submits the customer's
credit application and purchase order to a regional service center where Green
Tree personnel make an analysis of the creditworthiness of the proposed buyer.
The analysis includes a review of the applicant's     
 
                                       11
<PAGE>
 
   
paying habits, length and likelihood of continued employment, and certain other
factors. Green Tree uses a proprietary automated credit scoring system, which
is a statistically based scoring system that quantifies information using
variables obtained from customers' credit applications and credit reports.
Green Tree believes the use of this proprietary credit scoring system has
contributed to the reduction in the number of repossessions incurred as a
percentage of Green Tree's servicing portfolio. Manufactured housing contracts
are assumable by any individual who meets Green Tree's then-current
underwriting criteria. If the application meets Green Tree's guidelines and the
credit is approved, Green Tree purchases the contract after the manufactured
home is delivered and set up and the customer has moved in.     
   
    Green Tree computes the loan-to-value ratio for each contract by first
computing the percentage relationship that the down payment bears to the total
loan amount plus any cash down payment, plus, in certain cases, fees and
insurance premiums financed, then subtracting the result from one. The down
payment on some contracts, including land-and-home contracts, may include the
borrower's equity in land (based on the appraised value, discounted up to 20%,
less encumbrances), for which a lien has been granted to Green Tree. For
contracts in which a lien on land has been granted to Green Tree in lieu of or
as a supplement to a cash down payment, the loan-to-value ratio is computed by
dividing the appraised value of the land, discounted up to 20%, by the total
loan amount and subtracting the result from one. If the customer is refinancing
an existing loan, Green Tree may in some situations rely on an appraisal made
at the time the prior loan was originated. Manufactured homes, unlike site-
built homes, generally depreciate in value. Consequently, at any time after
origination it is possible, especially in the case of contracts with high loan-
to-value ratios at origination, that the market value of a manufactured home
may be lower than the principal amount outstanding under the related contract.

Pooling and Disposition of Contracts
   
    Green Tree generally pools contracts for sale to investors within 15 to 120
days of purchase. In the case of FHA-insured and VA-guaranteed manufactured
housing contracts,     
 
                                       12
<PAGE>
 
   
the Company generally issues modified pass-through certificates secured by the
contracts and guaranteed by the Government National Mortgage Association. The
GNMA certificates provide for the payment by Green Tree to registered holders
of GNMA certificates of monthly payments of principal and interest and the
"pass-through" of any prepayments of the contracts.     
   
    In the case of conventional manufactured housing contracts, Green Tree
sells pools of contracts through asset securitization vehicles such as the
trust funds described in this prospectus under "The Trust Fund." Green Tree
establishes a specified level of recourse, which may take the form of a
subordinated right to interest payments on the contracts, payable after the
payment of scheduled principal and interest on the related investor interests,
or a cash reserve fund for losses on the contracts comprising the pools. Upon a
default under a contract and a liquidation of the underlying collateral, any
net losses are charged against the established recourse amount or the reserve
fund.     
 
Servicing
   
    Green Tree services all of the manufactured housing contracts it originates
or purchases from other originators, collecting loan payments, taxes and
insurance payments where applicable and other payments from borrowers and
remitting principal and interest payments to the holders of the conventional
contracts or of the GNMA certificates backed by FHA-insured and VA-guaranteed
contracts.     
   
    The following table shows the composition of Green Tree's portfolio of
contracts that Green Tree originated, together with subserviced contracts not
originated by Green Tree, including manufactured housing contracts,
recreational vehicle contracts, motorcycle contracts, special product contracts
and home improvement contracts, on the dates indicated:

                              YIELD CONSIDERATIONS
   
    The remittance rates and the weighted average contract rate of the
contracts for each series of certificates are listed in the related prospectus
supplement.     
   
    Unless we specify otherwise in the related prospectus supplement, each
monthly accrual of interest on a contract is calculated at one-twelfth of the
product of the contract rate and the principal balance outstanding on the
scheduled payment date for that contract in the preceding month. Unless we
specify otherwise in the related prospectus supplement, the remittance rate for
each certificate will be calculated similarly.     
   
    The prospectus supplement for each series will indicate that a lower rate
of principal prepayments than anticipated would negatively affect the total
return to investors of any class of certificates that is offered at a discount
to its principal amount, and a higher rate of principal prepayments than
anticipated would negatively affect the total return to investors of any class
of certificates that is offered at a premium to its principal amount or without
any principal amount.     
   
    The yield on some types of certificates which we may offer, such as
interest only certificates, principal only certificates, and fast pay/slow pay
certificates, each as further described in this prospectus under "Description
of Certificates--General," may be particularly sensitive to prepayment rates,
and to changes in prepayment rates, on the underlying contracts. If so stated
in the related prospectus supplement, the yield on some types of certificates
which we may offer could change and may be negative under some prepayment rate
scenarios. Accordingly, some types of certificates may not be legal or
appropriate investments for some financial institutions, pension funds or
others. See "ERISA Considerations" and "Legal Investment Considerations" in
this prospectus and in the prospectus supplement. In addition, the timing of
changes in the rate of prepayment on the contracts included in a contract pool
may significantly affect an investor's actual yield to maturity, even if the
average prepayment rate over time is consistent with the investor's
expectations. In general, the earlier that prepayments on contracts occur, the
greater the effect on the investor's yield to maturity.     
   
    If a series of certificates contains classes of certificates entitled to
receive distributions of principal or interest or both, in a specified order
other than as a specified percentage of     
 
                                       14
<PAGE>
 
   
each distribution of principal or interest or both, the prospectus supplement
will show that information, measured relative to a prepayment standard or model
specified in that prospectus supplement, for the projected weighted average
life of each class and the percentage of the original principal of each class
that would be outstanding on specified remittance dates for that series based
on the assumptions stated in that prospectus supplement, including assumptions
that prepayments on the contracts in the related trust fund are made at rates
corresponding to the various percentages of the prepayment standard or model.
    
                     MATURITY AND PREPAYMENT CONSIDERATIONS
 
Maturity
   
    Unless otherwise described in an applicable prospectus supplement, all of
the contracts will have maturities at origination of not more than 30 years.
    
Prepayment Considerations
   
    Contracts generally may be prepaid in full or in part without penalty. FHA
contracts and VA contracts may be prepaid at any time without penalty. Based on
Green Tree's experience with the portfolio of manufactured housing contracts
serviced by it, Green Tree anticipates that a number of the contracts will be
prepaid prior to their maturity. A number of factors, including homeowner
mobility, general and regional economic conditions and prevailing interest
rates, may influence prepayments. In addition, repurchases of contracts on
account of breaches of representations and warranties have the effect of
prepaying the contracts and therefore would affect the average life of the
certificates. Most of the contracts contain a "due-on-sale" clause that would
permit the servicer to accelerate the maturity of a contract upon the sale of
the related manufactured home. In the case of those contracts that do contain
due-on-sale clauses, the servicer will permit assumptions of the contracts if
the purchaser of the related manufactured home satisfies Green Tree's then-
current underwriting standards.     
   
    Information regarding the prepayment model or any other rate of assumed
prepayment, as applicable, will be described in the prospectus supplement for a
series of certificates.     
   
    See "Description of the Certificates--Termination of the Agreement" for a
description of Green Tree's or the servicer's option to repurchase the
contracts comprising part of a trust fund when the aggregate outstanding
principal balance of the contracts is less than a specified percentage of the
initial aggregate outstanding principal balance of the contracts as of the
related cut-off date. See also "The Trust Fund--The Contract Pools" for a
description of Green Tree's obligations to repurchase a contract in case of a
breach of a representation or warranty for that contract.

                        DESCRIPTION OF THE CERTIFICATES
   
    Each series of certificates will be issued under a separate pooling and
servicing agreement to be entered into among Green Tree, as seller and
servicer, and the trustee named in the related prospectus supplement, and other
parties, as are described in the applicable prospectus supplement. The
following summaries describe provisions expected to be common to each agreement
and the related certificates, but do not purport to be complete and are subject
to, and are qualified in their entirety by reference to, the provisions of the
related agreement and its description in the related prospectus supplement.
Section references refer to sections of the form of agreement filed as an
exhibit to the registration statement of which this prospectus is a part. The
portions of these sections we describe in the prospectus may be contained in
different numbered sections in the actual agreement. The provisions of the form
of agreement filed as an exhibit to the registration statement that are not
described in this prospectus may differ from the provisions of any actual
agreement. The material differences will be described in the related prospectus
supplement. Capitalized terms not otherwise defined in this prospectus have the
meanings assigned to them in the form of agreement filed as an exhibit to the
registration statement containing this prospectus.     
   
    Each series of certificates will have been rated in the rating category by
the rating agency or agencies specified in the related prospectus supplement.
    
General
   
    The certificates may be issued in one or more classes. If the certificates
of a series are issued in more than one class, the certificates of all or less
than all of the classes may be sold under this prospectus, and there may be
separate prospectus supplements relating to one or more of the classes sold.
When we refer to the prospectus supplement relating to a series comprised of
more than one class it should be understood as a reference to each of the
prospectus supplements relating to the classes sold under this prospectus. When
we refer to the certificates of a class it should be understood to refer to the
certificates of a class within a series or all of the certificates of a single-
class series, as the context may require. For convenience of description, any
reference in this prospectus to a "class" of certificates includes a reference
to any subclass of that class.     
   
    The certificates of each series will be issued in fully registered form
only and will represent the interests specified in the related prospectus
supplement in a separate trust fund created under the related pooling and
servicing agreement. The trust fund will be held by the trustee for the benefit
of the certificateholders. Except as otherwise specified in the related
prospectus supplement, the certificates will be freely transferable and
exchangeable at the corporate trust office of the trustee at the address listed
in the related prospectus supplement. No service charge will be made for any
registration of exchange or transfer of certificates, but the trustee may
require payment of a sum sufficient to cover any tax or other governmental
charge.     
       
       
          
    Ownership of each contract pool may be evidenced by one or more classes of
certificates, each representing the interest in the contract pool specified in
the related     
 
                                       16
<PAGE>
 
   
prospectus supplement. Each series of certificates may include one or more
classes ("subordinated certificates") which are subordinated in right of
distribution to one or more other classes ("senior certificates"), as provided
in the related prospectus supplement. Certificates of a series which includes
senior and subordinated certificates are referred to in this prospectus
collectively as "senior/subordinated certificates." A series of senior/
subordinated certificates may include one or more classes ("mezzanine
certificates") which are subordinated to one or more classes of certificates
and are senior to one or more classes of certificates. The prospectus
supplement for a series of senior/subordinated certificates will describe the
extent to which the subordinated certificates are subordinated, which may
include a formula for determining the subordinated amount or for determining
the allocation of the amount available for distribution among senior
certificates and subordinated certificates, the allocation of losses among the
classes of subordinated certificates, the period or periods of subordination,
any minimum subordinated amount and any distributions or payments which will
not be affected by the subordination. The protection afforded to the senior
certificateholders from the subordination feature described above will be
effected by the preferential right of the certificateholders to receive current
distributions from the contract pool. If a series of certificates contains more
than one class of subordinated certificates, losses will be allocated among the
classes in the manner described in the prospectus supplement. If so specified
in the applicable prospectus supplement, mezzanine certificates or other
classes of subordinated certificates may be entitled to the benefits of other
forms of credit enhancement and may, if rated in one of the four highest rating
categories by a nationally recognized statistical rating organization, be
offered under this prospectus and the prospectus supplement.     
   
    If specified in a prospectus supplement, a series of certificates may
include one or more classes which:     
     
  (1) are entitled to receive distributions only in respect of principal
      ("principal only certificates"), interest ("interest only
      certificates") or any combination of the two, or in specified
      proportions of the payments, and/or     
     
  (2) are entitled to receive distributions of principal before or after
      specified principal distributions have been made on one or more other
      classes within a series ("fast pay/slow pay certificates"), or on a
      planned amortization schedule ("PAC certificates") or targeted
      amortization schedule ("TAC certificates") or upon the occurrence of
      other specified events.     
   
The prospectus supplement will list the pass-through rate at which interest
will be paid to certificateholders of each class of a given series. The pass-
through rate may be fixed, variable or adjustable, as specified in the related
prospectus supplement.     
   
    The related prospectus supplement will specify the minimum denomination or
initial principal amount of contracts evidenced by a single certificate of each
class of certificates of a series.     
   
    Distributions of principal and interest on the certificates will be made on
the remittance dates listed in the related prospectus supplement to the persons
in whose names the     
 
                                       17
<PAGE>
 
   
certificates are registered at the close of business on the related record date
specified in the related prospectus supplement (the "record date").
Distributions will be made by check mailed to the address of the person
entitled to the distribution as it appears on the certificate register, or, as
described in the related pooling and servicing agreement, by wire transfer,
except that the final distribution in retirement of certificates will be made
only upon presentation and surrender of the certificates at the office or
agency of the trustee specified in the final distribution notice to
certificateholders.     
 
Global Certificates
   
    The certificates of a class may be issued in whole or in part in the form
of one or more global certificates that will be deposited with, or on behalf
of, and registered in the name of a nominee for, a depositary identified in the
related prospectus supplement. The description of the certificates contained in
this prospectus assumes that the certificates will be issued in definitive
form. If the certificates of a class are issued in the form of one or more
global certificates, the term "certificateholder" should be understood to refer
to the beneficial owners of the global certificates, and the rights of the
certificateholders will be limited as described under this subheading.     
   
    Global certificates will be issued in registered form. Unless and until it
is exchanged in whole or in part for certificates in definitive form, a global
certificate may not be transferred except as a whole by the depositary for the
global certificate to a nominee of the depositary or by a nominee of the
depositary to the depositary or another nominee of the depositary or by the
depositary or any nominee to a successor of the depositary or a nominee of the
successor.     
   
    The specific terms of the depositary arrangement for any certificates of a
class will be described in the related prospectus supplement. It is anticipated
that the following provisions described in this subsection will apply to all
depositary arrangements.     
   
    Upon the issuance of a global certificate, the depositary for the global
certificate will credit, on its book-entry registration and transfer system,
the respective denominations of the certificates represented by the global
certificate to the accounts of institutions that have accounts with the
depositary ("participants"). Ownership of beneficial interests in a global
certificate will be limited to participants or persons that may hold interests
through participants. Ownership of beneficial interests in the global
certificate will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the depositary for the global
certificate or by participants or persons that hold through participants. The
laws of some states require that purchasers of securities take physical
delivery of the securities in definitive form. These limits and laws may impair
the ability to transfer beneficial interests in a global certificate.     
   
    So long as the depositary for a global certificate, or its nominee, is the
owner of the global certificate, the depositary or the nominee, as the case may
be, will be considered the sole owner or holder of the certificates represented
by the global certificate for all purposes     
 
                                       18
<PAGE>
 
   
under the pooling and servicing agreement relating to those certificates.
Except as described in the paragraph below, owners of beneficial interests in a
global certificate will not be entitled to have certificates of the series
represented by a global certificate registered in their names, will not receive
or be entitled to receive physical delivery of certificates of that series in
definitive form and will not be considered the owners or holders under the
pooling and servicing agreement governing those certificates.     
   
    Distributions or payments on certificates registered in the name of or held
by a depositary or its nominee will be made to the depositary or its nominee,
as the case may be, as the registered owner for the holder of the global
certificate representing the certificates. In addition, all reports required
under the applicable pooling and servicing agreement to be made to
certificateholders, as described below under "Reports to Certificateholders,"
will be delivered to the depositary or its nominee, as the case may be. Green
Tree, the servicer, trustee, or any agent, including any applicable certificate
registrar or paying agent, will not have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
ownership interests in a global certificate or for maintaining, supervising or
reviewing any records relating to the beneficial ownership interests or for
providing reports to the related beneficial owners.     
   
    Green Tree expects that the depositary for certificates of a class, upon
receipt of any distribution or payment on a global certificate, will credit
immediately participants' accounts with payments in amounts proportionate to
their respective beneficial interest in the global certificate as shown on the
records of the depositary. Green Tree also expects that payments by
participants to owners of beneficial interests in the global certificate held
through participants will be governed by standing instructions and customary
practices, as is now the case with securities held for the accounts of
customers registered in street name, and will be the responsibility of the
participants.     
   
    If a depositary for certificates of a class is at any time unwilling or
unable to continue as depositary and a successor depositary is not appointed by
or on behalf of Green Tree within the time period specified in the pooling and
servicing agreement, Green Tree will cause to be issued certificates of that
class in definitive form in exchange for the related global certificate or
certificates. In addition, Green Tree may at any time and in its sole
discretion determine not to have any certificates of a class represented by one
or more global certificates and, if this occurs, will cause to be issued
certificates of that class in definitive form in exchange for the related
global certificate or certificates. Further, if Green Tree so specifies that
the certificates of a class, an owner of a beneficial interest in a global
certificate representing certificates of that class may, on terms acceptable to
Green Tree and the depositary for the global certificate, receive certificates
of that class in definitive form. In any such instance, an owner of a
beneficial interest in a global certificate will be entitled to physical
delivery in definitive form of certificates of the class represented by the
global certificate equal in denominations to the beneficial interest and to
have the certificates registered in its name.

Distributions on Certificates
   
    Except as otherwise provided in the related prospectus supplement, on each
remittance date, the trustee will withdraw from the applicable certificate
account and distribute to the certificateholders of each class, other than a
series having a class of subordinated certificates, as described below, either
the specified interest of the class in the contract pool times the aggregate of
all amounts on deposit in the certificate account as of the third business day
preceding the remittance date or another date as may be specified in the
related prospectus supplement (the "Determination Date"), or, in the case of a
series of certificates comprised of classes which have been assigned a Stated
Balance, payments of interest and payments in reduction of the Stated Balance
from all amounts on deposit in the certificate account on the Determination
Date, in the priority and calculated in the manner described in the related
prospectus supplement, except, in each case:     
     
  (1) all payments on the contracts that were due on or before the cut-off
      date;     
     
  (2) all payments or collections received after the due period preceding
      the month in which the remittance date occurs;     
     
  (3) all scheduled payments of principal and interest due on a date or
      dates subsequent to the due period preceding the Determination Date;
             
  (4) amounts representing reimbursement for Advances, these reimbursement
      being limited, if specified in the related prospectus supplement, to
      amounts received on particular contracts as late collections of
      principal or interest as to which the servicer has made an
      unreimbursed Advance; and     
     
  (5) amounts representing reimbursement for any unpaid servicing fee and
      expenses from Liquidation Proceeds, condemnation proceeds and proceeds
      of insurance policies with respect to the related contracts. The
      amount of principal and interest specified in the related prospectus
      supplement to be distributed to certificateholders is referred to in
      this prospectus as the "Certificate Distribution Amount." The amounts
      on deposit in the certificate account on a Determination Date, less
      the amounts specified in (1) through (5) above, are referred to in
      this prospectus as the "amount available."     
   
    Unless otherwise specified in the related prospectus supplement, for a
series of certificates having a class of subordinated certificates, on each
remittance date, the trustee will withdraw from the applicable certificate
account and distribute to the holders of senior certificates, in the aggregate,
the lesser of (1) the Senior Distribution Amount plus the Outstanding Senior
Shortfall (each defined below in this section), or (2) the percentage interest
which may vary as specified in the related prospectus supplement of the classes
of senior certificates times the amount available plus (a) the percentage
interest which may vary as specified in the related prospectus supplement of
the classes of subordinated certificates times the amount available, not to
exceed the Available Subordination Amount, if any, as defined in the related
prospectus supplement, and (b) Advances, if any, made by the servicer. The
distribution made to the certificateholders of each class of senior
certificates shall be calculated as described in the related prospectus
supplement and may vary as to the     
 
                                       20
<PAGE>
 
   
allocation of principal or interest or both. Unless otherwise specified in the
related prospectus supplement, the Senior Distribution Amount is an amount
equal to the percentage interest of the classes of senior certificates times:
       
  (1) all regularly scheduled payments of principal of and interest which
      were due on contracts during the related due period, whether or not
      received, with the interest portions adjusted to the remittance rate;
             
  (2) all principal prepayments made by the obligor during the prior due
      period;     
     
  (3)  for each contract not described in (4) below, all insurance proceeds,
       all condemnation awards and any other cash proceeds from a source
       other than the obligor, as required to be deposited in the
       certificate account, which were received during the prior due period,
       net of related unreimbursed Advances and net of any portion thereof
       which, as to any contract, constitutes late collections;     
     
  (4) for each contract as to which a receipt of Liquidation Proceeds has
      been received during the prior due period or other event of
      termination of the contract has occurred during the prior due period,
      an amount equal to the principal amount of the contract outstanding
      immediately before the date of receipt of the Liquidation Proceeds or
      other event of termination, reduced by the principal portion of any
      unpaid payments due on or before that date to the extent previously
      advanced against or otherwise received by the certificateholder, plus
      interest from the most recent due date at the remittance rate; and
             
  (5) for each contract repurchased by Green Tree for which the repurchase
      price was not distributed previously, an amount equal to the principal
      amount of the contract outstanding on the date of the repurchase
      reduced by the principal portion of any unpaid payments due on or
      before that date, but only to the extent advanced against or otherwise
      received by the certificateholders, plus interest to the most recent
      due date.     
   
    The Outstanding Senior Shortfall for any class of senior certificates means
as of any date, to the extent not previously paid, the aggregate of the amounts
by which the Senior Distribution Amount for that class for any remittance date
exceeded the amount actually paid on that remittance date plus interest at the
remittance rate.     
   
    Unless otherwise specified in the related prospectus supplement, on each
remittance date, the servicer shall distribute to the classes of subordinated
certificateholders, in the order listed in the related prospectus supplement,
the balance of the amount available for distribution, if any, after the payment
to the senior certificateholders, as described above.     
   
    Unless otherwise specified in the prospectus supplement relating to a
series of certificates, one or more classes of which have been assigned a
Stated Balance, distributions in reduction of the Stated Balance of the
certificates will be made on each remittance date to the certificateholders of
the class then entitled to receive the certificate distributions until the
aggregate amount of the distributions have reduced the Stated Balance of the
certificates of that class to zero or a specified percentage. Allocation of
distributions in reduction of Stated     
 
                                       21
<PAGE>
 
   
Balance will be made to each class of certificates in the order specified in
the related prospectus supplement, which, if so specified in the prospectus
supplement, may be concurrently. Unless otherwise specified in the related
prospectus supplement, distributions in reduction of the Stated Balance of each
certificate of a class then entitled to receive distributions will be made pro
rata among the certificates of that class.     
   
    Unless otherwise specified in the related prospectus supplement, the
maximum amount which will be distributed in reduction of Stated Balance to
holders of certificates of a class then entitled to a distribution on any
remittance date will equal, to the extent funds are available, the sum of:     
     
  (1) the amount of the interest, if any, that has accrued but is not yet
      payable on the Compound Interest Certificates of that series, if any,
      from the prior remittance date or since the date specified in the
      related prospectus supplement in the case of first Remittance Date
      (the "Accrual Remittance Amount"); and     
     
  (2) the Certificate Remittance Amount; and     
     
  (3) the applicable percentage of the Excess Cash Flow, if any, specified
      in the Prospectus Supplement.     
   
    Unless otherwise specified in the related prospectus supplement, the
Certificate Remittance Amount for a remittance date will equal the amount, if
any, by which the then outstanding Stated Balance of the certificates of the
related classes of series (before taking into account the amount of interest
accrued on any class of Compound Interest Certificates of that series to be
added to the Stated Balance on the remittance date) exceeds the Asset Value, as
defined in the related prospectus supplement, of the contracts in the contract
pool underlying the series as of the end of the applicable Due Period specified
in the related prospectus supplement. For purposes of determining the
Certificate Remittance Amount for a remittance date, the Asset Value of the
contracts will be reduced to take into account the interest evidenced by the
classes of certificates in the principal distributions for those contracts
received by the trustee during the preceding due period.     
   
    Unless otherwise specified in the prospectus supplement relating to a
series of certificates, one or more classes of which have been assigned a
Stated Balance, Excess Cash Flow represents the excess of (1) the interest
evidenced by the classes of certificates in the distributions received on the
contracts underlying the series in the due period preceding a remittance date
for that series and, in the case of the first due period, the amount deposited
in the certificate account on the closing date for the sale of the
certificates, together with income from the reinvestment of the interest, (2)
the sum of all interest accrued, whether or not then payable, on the
certificates of the classes since the preceding remittance date or since the
date specified in the related prospectus supplement in the case of the first
remittance date, the Certificate Remittance Amount for the then current
remittance date and, if applicable, any payments made on any certificates of
the class under any special distributions in reduction of Stated Balance during
the due period.     
 
 
                                       22
<PAGE>
 
   
    Within the time specified in the pooling and servicing agreement and
described in the related prospectus supplement, the servicer will furnish a
statement to the trustee listing the amount to be distributed on the related
remittance date on account of principal and interest, stated separately, and a
statement providing information on the contracts.     
   
    If there are not sufficient funds in the certificate account to make the
full distribution to certificateholders described above on any remittance date,
the servicer will distribute the funds available for distribution to the
certificateholders of each class in accordance with their respective interests,
except that any subordinated certificateholders, will not, subject to the
limitations described in the related prospectus supplement, receive any
distributions until senior certificateholders receive the Senior Distribution
Amount plus the Outstanding Senior Shortfall. The difference between the amount
which the certificateholders would have received if there had been sufficient
eligible funds in the certificate account and the amount actually distributed,
plus interest at the remittance rates of the respective contracts to which such
shortfall is attributable, will be added to the amount which the
certificateholders are entitled to receive on the next remittance date.     
   
    Special Distributions. To the extent specified in the prospectus supplement
relating to a series of certificates, one or more classes of which have been
assigned a Stated Balance and having less frequent than monthly remittance
dates, these classes may receive Special Distributions in reduction of Stated
Balance ("Special Distributions") in any month, other than a month in which a
remittance date occurs, if, as a result of principal prepayments on the
contracts in the related contract pool or low reinvestment yields, the trustee
determines, based on assumptions specified in the related agreement, that the
amount of cash anticipated to be on deposit in the certificate account on the
next remittance date for that series and available to be distributed to the
holders of the certificates of these classes may be less than the sum of:     
     
  (1) the interest scheduled to be distributed to holders of the
      certificates of those classes; and     
     
  (2) the amount to be distributed in reduction of Stated Balance of those
      certificates on the remittance date.     
   
Any Special Distributions will be made in the same priority and manner as
distributions in reduction of Stated Balance would be made on the next
remittance date.     
   
    Subordinated Certificates. The rights of a class of certificateholders of a
series to receive any or a specified portion of distributions of principal or
interest or both on the contracts, to the extent specified in the related
pooling and servicing agreement and described in the related prospectus
supplement, may be subordinated to the rights of other certificateholders. The
prospectus supplement for a series of certificates having a class of
subordinated certificates will describe the extent to which the class is
subordinated (which may include a formula for determining the subordinated
amount or for determining the allocation of the amount available among senior
certificates and subordinated certificates), the allocation of losses among the
classes of subordinated certificates, the period or periods of subordination,
and minimum subordinated amount and any distributions or payments     
 
                                       23
<PAGE>
 
   
which will not be affected by the subordination. The protection afforded to the
senior certificateholders from this subordination feature will be effected by
the preferential right of the certificateholders to receive current
distributions from the contract pool.     
 
Example of Distributions
   
    The following is an example of the flow of funds as it would relate to a
hypothetical series of certificates issued, and with a cut-off date occurring,
on January 15, 1999. All days are assumed to be business days. The initial
principal balance of the contract pool will be the aggregate principal balance
of the contracts at the close of business on the cut-off date, after deducting
principal payments due on or before that date, which, together with
corresponding interest payments, are not part of the contract pool and will not
be passed through to certificateholders. Scheduled payments and principal
prepayments may be received at any time during the due period and will be
deposited in the certificate account by the servicer for distribution to
certificateholders. When a contract is prepaid in full, interest on the amount
prepaid is collected from the obligor only to the date of payment.
Distributions on March 1 will be made to certificateholders of record at the
close of business on the business day immediately preceding the related
remittance date. On February 25 (the third business day before the remittance
date), the servicer will determine the amounts of principal and interest which
will be passed through on March 1. In addition, the servicer may advance funds
to cover any delinquencies, in which event the distribution to
certificateholders on March 1 will include the full amounts of principal and
interest due during the related due period. The servicer will also calculate
any changes in the relative interests evidenced by the senior certificates and
the subordinated certificates in the trust fund. On March 1, the amounts
determined on February 25 will be distributed to certificateholders.

    Succeeding months follow the pattern of the due period through the
remittance date. The flow of funds for any series of certificates may differ
from the above example, as specified in the related prospectus supplement.     
       
       
       
       
Reports to Certificateholders
   
    The trustee will forward to each certificateholder on each remittance date,
or as soon thereafter as is practicable, as specified in the related prospectus
supplement, a statement listing the following information:     
     
  (1) the amount of distribution allocable to principal on the contracts;
             
  (2)  the amount of the distribution allocable to interest on the
      contracts;     
 
 
                                       24
<PAGE>
 
     
  (3)  if the distribution to the certificateholders is less than the full
       amount that would be distributable to the certificateholders if there
       were sufficient eligible funds in the certificate account, the
       difference between the aggregate amounts of principal and interest
       which certificateholders would have received if there were sufficient
       eligible funds in the certificate account and the amounts actually
       distributed;     
     
  (4)  the aggregate amount of any Advance by the servicer included in the
       amounts actually distributed to the certificateholders;     
     
  (5)  the outstanding principal balance of the contracts; and     
     
  (6) the approximate weighted average remittance rate of the contracts
     during the due period immediately preceding the remittance date.     
   
    In addition, not more than 90 days after the end of each calendar year, the
servicer will furnish a report to each certificateholder of record at any time
during that calendar year (a) as to the aggregate of amounts reported pursuant
to (1) through (5) above for that calendar year or, if the person was a
certificateholder of record during a portion of that calendar year, for the
applicable portion of that year, (b) other information as the servicer deems
necessary or desirable for certificateholders to prepare their tax returns and
(c) if so specified in the related prospectus supplement, a listing of the
principal balances of the contracts outstanding at the end of the calendar
year. Information in the monthly and annual reports provided to the
certificateholders will not have been examined and reported upon by an
independent public accountant. However, the servicer will provide to the
trustee annually a report by independent public accountants regarding the
servicing of the contracts as described under "Evidence as to Compliance"
above.     
       
    In addition, to the extent applicable, the report shall include:     
     
  (1) in the case of certificates which are assigned a Stated Balance, the
      amount of the distribution being made in reduction of Stated Balance
      specified in the related prospectus supplement, and the Stated Balance
      of each class of certificates and a Single Certificate of the holder's
      class after giving effect to the distribution in reduction of Stated
      Balance made on such remittance date and after giving effect to all
      Special Distributions since the preceding remittance date or since the
      closing date in the case of the first remittance date; and     
     
  (2)  for Compound Interest Certificates, but only if the holders of those
       certificates shall not have received on the remittance date a
       distribution of interest equal to the entire amount of interest
       accrued on the certificate during the related due period remittance
       date:     
        
     .  the interest accrued on the class of Compound Interest Certificates
        and on a Single Certificate of that class during the due period, or
        specified interest accrual period, for that remittance date and
        added to the principal of that Compound Interest Certificates; and
               
     .  the Stated Balance of the class of Compound Interest Certificates
        and of a Single Certificate of that class after giving effect to
        the addition of all interest     
 
                                       25
<PAGE>
 
           
        accrued during the due period, or specified interest accrual period
        for that remittance date.     
   
Advances     
   
    To the extent provided in the related prospectus supplement, the servicer
is obligated to make periodic Advances of cash from its own funds or, if
specified in the related prospectus supplement, from excess funds in the
certificate account not then required to be distributed to certificateholders,
for distribution to the certificateholders in an amount equal to the difference
between the amount due to them and the amount in the certificate account,
eligible for distribution to them under the pooling and servicing Agreement,
but only to the extent the difference is due to delinquent payments of
principal and interest for the preceding due period and only to the extent the
servicer determines the advances are recoverable from future payments and
collections on the delinquent contracts. The servicer's obligation to make any
Advances, may, as specified in the related prospectus supplement, be limited in
amount. If specified in the related prospectus supplement, the servicer will
not be obligated to make Advances until all or a specified portion of any
Reserve Fund is depleted. Advances are intended to maintain a regular flow of
scheduled interest and principal payments to the senior certificateholders, not
to guarantee or insure against losses. Accordingly, any funds advanced are
recoverable by the servicer out of amounts received on particular contracts
which represent late recoveries of principal or interest for which any Advance
was made.     
   
Indemnification     
   
    The pooling and servicing agreement requires Green Tree to defend and
indemnify the trust fund, the trustee, including any agent of the trustee and
the certificateholders (which indemnification will survive any removal of the
servicer as servicer of the contracts) against any and all costs, expenses,
losses, damages, claims and liabilities, including reasonable fees and expenses
of counsel and expenses of litigation (1) arising out of or resulting from the
use or ownership by Green Tree or the servicer or any of its affiliates of any
manufactured home and (2) for any taxes which may at any time be asserted for,
and as of the date of, the conveyance of the contracts to the trust fund but
not including any federal, state or other tax arising out of the creation of
the trust fund and the issuance of the certificates. (Article X).     
   
    The pooling and servicing agreement also requires the servicer, in its
duties as servicer of the contracts, to defend and indemnify the trust fund,
the trustee and the certificateholders (which indemnification will survive any
removal of the servicer as servicer of the contracts) against any and all
costs, expenses, losses, damages, claims and liabilities, including reasonable
fees and expenses of counsel and expenses of litigation, for any action taken
by the servicer on any contract while it was the servicer. (Section 10.04.)
    
Amendment
   
    Unless otherwise specified in the related prospectus supplement, the
pooling and servicing agreement may be amended by Green Tree, the servicer and
the trustee without the consent of the certificateholders:     
 
                                       26
<PAGE>
 
     
  .  to cure any ambiguity; or     
     
  .  to correct or supplement any provision in the agreement that may be
     inconsistent with another provision; or     
     
  .  if an election has been made for a particular series of certificates to
     treat the trust fund as a REMIC within the meaning of Section 860D(a)
     of the Internal Revenue Code, to maintain the REMIC status of the trust
     fund and to avoid the imposition of certain taxes on the REMIC; or     
     
  .  to make any other provisions on matters or questions arising under the
     agreement that are not inconsistent with its provisions, provided that
     the action will not adversely affect in any material respect the
     interests of the certificateholders of the related series.     
   
Unless otherwise specified in the related prospectus supplement, the pooling
and servicing agreement may also be amended by Green Tree, the servicer and the
trustee with the consent of the certificateholders, other than holders of
Residual Certificates, evidencing interests aggregating not less than 51% of
the trust fund for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the pooling and servicing
agreement or of modifying in any manner the rights of the certificateholders;
provided, however, that no amendment that reduces in any manner the amount of,
or delay the timing of, any payment received on contracts which are required to
be distributed on any certificate may be effective without the consent of the
holders of each certificate.     
 
Termination of the Agreement
   
    The obligations created by each pooling and servicing agreement will
terminate upon the date calculated as specified in the pooling and servicing
agreement, generally upon:     
     
  (1) the later of the final payment or other liquidation of the last
      contracts subject to the agreement and the disposition of all property
      acquired upon foreclosure of any land-and-home contract or
      repossession of any manufactured home; and     
     
  (2) the payment to the certificateholders of all amounts held by the
      servicer or the trustee and required to be paid to it under to the
      agreement.     
   
In addition, unless otherwise specified in the related prospectus supplement,
Green Tree or the servicer may at its option regarding any series of
certificates, repurchase all certificates or contracts remaining outstanding at
that time as the aggregate unpaid principal balance of contracts is less than
the percentage of the aggregate unpaid principal balance of the contracts on
the cut-off date specified for that series in the related prospectus
supplement. Unless otherwise provided in the related prospectus supplement, the
repurchase price will equal the principal amount of the contracts plus accrued
interest from the first day of the month of repurchase to the first day of the
next succeeding month at the contract rates borne by the contracts.     
 
 
                                       27
<PAGE>
 
The Trustee
   
    The prospectus supplement for a series of certificates will specify the
trustee under the related pooling and servicing agreement. The trustee may have
normal banking relationships with Green Tree or its affiliates and the servicer
or its affiliates.     
   
    The trustee may resign at any time, in which event Green Tree will be
obligated to appoint a successor trustee. Green Tree may also remove the
trustee if the trustee ceases to be eligible to continue as trustee under the
pooling and servicing agreement or if the trustee becomes insolvent. Unless
otherwise specified in the related prospectus supplement, the trustee may also
be removed at any time by the holders of certificates evidencing interests
aggregating over 50% of the related trust fund as specified in the pooling and
servicing agreement. Any resignation or removal of the trustee and appointment
of a successor trustee will not become effective until acceptance of the
appointment by the successor trustee.     
   
    The trustee will make no representation as to the validity or sufficiency
of the pooling and servicing agreement, the certificates, any contract,
contract file or related documents, and will not be accountable for the use or
application by Green Tree of any funds paid to Green Tree, as seller, in
consideration of the conveyance of the contracts, or deposited into or
withdrawn from the certificate account by the servicer. (Section 11.03.) If no
event of termination has occurred, the trustee will be required to perform only
those duties specifically required of it under the pooling and servicing
agreement. However, upon receipt of the various certificates, reports or other
instruments required to be furnished to it, the trustee will be required to
examine them to determine whether they conform as to form to the requirements
of the pooling and servicing agreement. (Section 11.01.) Whether or not an
event of termination has occurred, the trustee is not required to expend or
risk its own funds or otherwise incur any financial liability in the
performance of its duties or the exercise of its powers if it has reasonable
grounds to believe that repayment of the funds or adequate indemnity against
the risk or liability is not reasonably assured to it. (Section 11.01.)     
   
    Under the pooling and servicing agreement, the servicer agrees to pay to
the trustee on each remittance date:     
     
  .  reasonable compensation for all services rendered by it under the
     agreement, which compensation shall not be limited by any provision of
     law regarding the compensation of a trustee of an express trust; and
            
  .  reimbursement for all reasonable expenses, disbursements and advances
     incurred or made by the trustee in accordance with any provision of the
     agreement, including the reasonable compensation and the expenses and
     disbursements of its agents and counsel, except any expense,
     disbursement or advance attributable to the trustee's negligence or bad
     faith.     
   
Green Tree has agreed to indemnify the trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad
faith on its part, arising out of or in connection with the acceptance or
administration of the trust fund and the trustee's duties     
 
                                       28
<PAGE>
 
   
thereunder, including the costs and expenses of defending itself against any
claim or liability in the exercise or performance of any of the trustee's
powers or duties. (Section 11.05.)     
                                    
                                 SERVICING     
   
    Under the pooling and servicing agreement, the servicer will service and
administer the contracts assigned to the trustee as more fully described below
in this section. The servicer will perform diligently all services and duties
specified in each pooling and servicing agreement, in the same manner as
prudent lending institutions of manufactured housing contracts of the same type
as the contracts in those jurisdictions where the related manufactured homes
are located or as otherwise specified in the pooling and servicing agreement.
The duties to be performed by the servicer will include collection and
remittance of principal and interest payments, collection of insurance claims
and, if necessary, repossession.     
   
    The servicer will make reasonable efforts to collect all payments called
for under the contracts and, consistent with the pooling and servicing
agreement and any FHA insurance and VA guaranty, will follow the collection
procedures as it follows for mortgage loans or contracts serviced by it that
are comparable to the contracts.     
   
    Hazard Insurance. Except as otherwise specified in the related prospectus
supplement, the terms of the pooling and servicing agreement will require the
servicer to cause to be maintained for each contract one or more hazard
insurance policies which provide, at a minimum, the same coverage as a standard
form fire and extended coverage insurance policy that is customary for
manufactured housing, issued by a company authorized to issue policies in the
state in which the manufactured home is located, and in an amount which is not
less than the maximum insurable value of the manufactured home or the principal
balance due from the obligor on the related contract, whichever is less;
provided, however, that the amount of coverage provided by each hazard
insurance policy shall be sufficient to avoid the application of any co-
insurance clause contained in the policy. Each hazard insurance policy caused
to be maintained by the servicer shall contain a standard loss payee clause in
favor of the servicer and its successors and assigns. If any obligor is in
default in the payment of premiums on its hazard insurance policy or policies,
the servicer shall pay the premiums out of its own funds, and may add
separately the premium to the obligor's obligation as provided by the contract,
but may not add the premium to the remaining principal balance of the contract.
       
    The servicer may maintain, in lieu of causing individual hazard insurance
policies to be maintained for each manufactured home, and shall maintain, to
the extent that the related contract does not require the obligor to maintain a
hazard insurance policy for the related manufactured home, one or more blanket
insurance policies covering losses on the obligor's interest in the contracts
resulting from the absence or insufficiency of individual hazard insurance
policies. Any blanket policy shall be substantially in the form and in the
amount carried by the servicer as of the date of the agreement. The servicer
shall pay the premium for the policy on the basis described in the policy and
shall pay any deductible amount for     
 
                                       29
<PAGE>
 
   
claims under the policy relating to the contracts. If the insurer thereunder
shall cease to be acceptable to the servicer, the servicer shall exercise its
best reasonable efforts to obtain from another insurer a replacement policy
comparable to the policy.     
   
    If the servicer shall have repossessed a manufactured home on behalf of the
trustee, the servicer shall either:     
     
  (1) maintain at its expense hazard insurance for the manufactured home, or
             
  (2) indemnify the trustee against any damage to the manufactured home
      before resale or other disposition.     
   
    Evidence as to Compliance. Unless otherwise specified in the related
prospectus supplement, each pooling and servicing agreement will require the
servicer to deliver to the trustee a monthly report before each remittance
date, describing information about the contract pool and the certificates of
the series as is specified in the related prospectus supplement. Each report to
the trustee will be accompanied by a statement from an appropriate officer of
the servicer certifying the accuracy of the report and stating that the
servicer has not defaulted in the performance of its obligations under the
pooling and servicing agreement. On or before May 1 of each year, the servicer
will deliver to the trustee a report of a firm of independent public
accountants which is a member of the American Institute of Certified Public
Accountants stating that the firm has examined documents, records and
managements' assertions relating to loans serviced by the servicer and stating
that, on the basis of that procedures, the servicing has been conducted in
compliance with the minimum servicing standards identified in the Mortgage
Bankers Association of America's Uniform Single Attestation Program for
Mortgage Bankers, or any successor program, except for any significant
exceptions or errors in records that, in the opinion of the firm, generally
accepted attestation standards require it to report. (Article VI.)     
   
    About the Servicer. The servicer may not resign from its obligations and
duties under a pooling and servicing agreement except upon a determination that
its duties under the pooling and servicing agreement are no longer permissible
under applicable law. No resignation will become effective until the trustee or
a successor servicer has assumed the servicer's obligations and duties under
the Agreement. The servicer can only be removed as servicer under to an event
of termination as discussed below under "--Event of Termination". Any person
with which the servicer is merged or consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the servicer is a party,
or any person succeeding to the business of the servicer, will be the successor
to the servicer under the pooling and servicing agreement so long as such
successor services at least $100 million of manufactured housing contracts.
(Section 12.01.)     
   
    Unless otherwise specified in the related prospectus supplement, each
Agreement will also provide that neither the servicer, nor any director,
officer, employee or agent of the servicer, will be under any liability to the
trust fund or the certificateholders for any action taken or for restraining
from the taking of any action in good faith under the Agreement, or for errors
in judgment; provided, however, that neither the servicer nor any such person
will     
 
                                       30
<PAGE>
 
   
be protected against any liability which would otherwise be imposed by reason
of the failure to perform its obligations in strict compliance with the
standards of care described in the pooling and servicing agreement. The
servicer may, in its discretion, undertake any action which it may deem
necessary or desirable with respect to the pooling and servicing agreement and
the rights and duties of the parties to the agreement and the interests of the
certificateholders. In such event, the legal expenses and costs of the action
and any liability resulting from the action will be expenses, costs and
liabilities of the trust fund and the servicer will be entitled to be
reimbursed out of the certificate account.     
   
    The servicer shall keep in force throughout the term of the pooling and
servicing agreement:     
     
  .  policy or policies of insurance covering errors and omissions for
     failure to maintain insurance as required by the pooling and servicing
     agreement, and     
     
  .  a fidelity bond.     
   
The policy or policies and the fidelity bond shall be in the form and amount as
is generally customary among persons which service a portfolio of manufactured
housing contracts having an aggregate principal amount of $100 million or more
and which are generally regarded as servicers acceptable to institutional
investors.     
   
    The servicer, to the extent practicable, shall cause the obligors to pay
all taxes and similar governmental charges when and as due. To the extent that
nonpayment of any taxes or charges would result in the creation of a lien upon
any manufactured home having a priority equal or senior to the lien of the
related contract, the servicer shall advance any delinquent tax or charge.     
   
    Servicing Compensation and Payment of Expenses. For its servicing of the
contracts, the servicer will receive servicing fees which include a monthly
servicing fee, which Green Tree may assign, for each due period, paid on the
next succeeding remittance date, equal to 1/12th of the product of 0.50% and
the pool scheduled principal balance for the immediately preceding remittance
date. As long as Green Tree is the servicer the trustee will pay Green Tree its
monthly servicing fee from any monies remaining after the certificateholders
have received all payments of principal and interest for the remittance date.
       
    The monthly servicing fee provides compensation for customary manufactured
housing contract third-party servicing activities to be performed by the
servicer for the trust fund and for additional administrative services
performed by the servicer on behalf of the trust fund. Customary servicing
activities include collecting and recording payments, communicating with
obligors, investigating payment delinquencies, providing billing and tax
records to obligors and maintaining internal records on each contract.
Administrative services performed by the servicer on behalf of the trust fund
include calculating distributions to certificateholders and providing related
data processing and reporting services for certificateholders and on behalf of
the trustee. Expenses incurred in servicing the contracts and paid by the
servicer from its servicing fees include, payment of fees and expenses of     
 
                                       31
<PAGE>
 
   
accountants, payments of all fees and expenses incurred in the enforcement of
contracts except Liquidation Expenses and payment of expenses incurred in
distributions and reports to certificateholders. The servicer will be
reimbursed out of the Liquidation Proceeds of a Liquidated Contract for all
ordinary and necessary Liquidation Expenses incurred by it in realization upon
the related manufactured home. (Section 5.08.)     
   
    As part of its servicing fees the servicer will also be entitled to retain,
as compensation for the additional services provided, any fees for late
payments made by obligors, extension fees paid by obligors for the extension of
scheduled payments and assumption fees for permitted assumptions of contracts
by purchasers of the related manufactured homes. (Section 1.02.)     
   
    Events of Termination. Except as otherwise specified in the related
prospectus supplement, events of termination under each agreement will include:
       
  .  any failure by the servicer to distribute to the certificateholders any
     required payment which continues unremedied for 5 days, or another
     period specified in the related prospectus supplement after the giving
     of written notice;     
     
  .  any failure by the servicer duly to observe or perform in any material
     respect any other of its covenants or agreements in the agreement that
     materially and adversely affects the interests of certificateholders,
     which, in either case, continues unremedied for 30 days after the
     giving of written notice of the failure of breach;     
     
  .  any assignment or delegation by the servicer of its duties or rights
     under the agreement, except as specifically permitted under the
     agreement, or any attempt to make an assignment or delegation;     
     
  .  events of insolvency, readjustment of debt, marshalling of assets and
     liabilities or similar proceedings regarding the servicer; and     
     
  .  the servicer is no longer an eligible servicer as defined in the
     applicable agreement. Notice as used in the agreement shall mean notice
     to the servicer by the trustee or Green Tree, or to Green Tree, the
     servicer, if any, and the trustee by the holders of certificates
     representing interests aggregating not less than 25% of the trust fund.
            
    Rights Upon Event of Termination. Except as otherwise specified in the
related prospectus supplement, so long as an event of termination remains
unremedied, the trustee may, and at the written direction of the
certificateholders of a series evidencing interests aggregating 25% or more of
the related trust fund, shall, terminate all of the rights and obligations of
the servicer under the related pooling and servicing agreement and in and to
the contracts, and the proceeds of the contracts, at which time subject to
applicable law regarding the trustee's ability to make advances the trustee or
a successor servicer under the agreement will succeed to all the
responsibilities, duties and liabilities of the servicer under the agreement
and will be entitled to similar compensation arrangements; provided, however,
that neither the trustee nor any successor servicer will assume any obligation
of Green Tree to repurchase contracts for breaches of representations or
warranties, and the trustee and the successor servicer will not be liable for
any acts or omissions of the prior servicer occurring     
 
                                       32
<PAGE>
 
   
before a transfer of the servicer's servicing and related functions or for any
breach by the servicer of any of its obligations contained in the agreement.
Notwithstanding the termination, the servicer shall be entitled to payment of
amounts payable to it before termination, for services rendered before
termination. No termination will affect in any manner Green Tree's obligation
to repurchase contracts for breaches of representations or warranties under the
agreement. If the trustee is obligated to succeed the servicer but is unwilling
or unable, it may appoint, or petition to a court of competent jurisdiction for
the appointment of a servicer. Pending the appointment, the trustee is
obligated to act in that capacity. The trustee and the successor may agree upon
the servicing compensation to be paid, which in no event may be greater than
the compensation to the servicer under the agreement.     
   
    No certificateholder will have any right under a pooling and servicing
agreement to institute any proceeding regarding the Agreement unless the holder
previously has given to the trustee written notice of default and unless the
holders of certificates evidencing interests aggregating not less than 25% of
the related trust fund requested the trustee in writing to institute the
proceeding in its own name as trustee and have offered to the trustee
reasonable indemnity and the trustee for 60 days has neglected or refused to
institute any proceeding. The trustee will be under no obligation to take any
action or institute, conduct or defend any litigation under the pooling and
servicing agreement at the request, order or direction of any of the holders of
certificates, unless the certificateholders have offered to the trustee
reasonable security or indemnity against the costs, expenses and liabilities
which the trustee may incur.     
 
 
                 DESCRIPTION OF FHA INSURANCE AND VA GUARANTEES
   
    Certain of the contracts may be FHA-insured or VA-guaranteed, the payments
upon which, subject to the following discussion, are insured by the FHA under
Title I of the National Housing Act or partially guaranteed by the VA.     
   
    The regulations governing FHA manufactured home insurance provide that
insurance benefits are payable upon the repossession and resale of the
collateral and assignment of the contract to HUD. For a defaulted FHA contract,
the servicer must follow applicable regulations before initiating repossession
procedures. These regulations include requirements that the lender arrange a
face-to-face meeting with the borrower, initiate a modification or repayment
plan, if feasible, and give the borrower 30 days' notice of default before any
repossession. The insurance claim is paid in cash by HUD. For manufactured
housing contracts, the amount of insurance benefits generally paid by FHA is
equal to 90% of the sum of:     
     
  (1) the unpaid principal amount of the contract at the date of default and
      uncollected interest earned to the date of default computed at the
      contract rate, after deducting the best price obtainable for the
      collateral, based in part on a HUD-approved     
 
                                       33
<PAGE>
 
        
     appraisal, and all amounts retained or collected by the lender from
     other sources regarding the contract; and     
     
  (2) accrued and unpaid interest on the unpaid amount of the contract from
      the date of default to the date of submission of the claim plus 15
      calendar days, but in no event more than nine months, computed at a
      rate of 7% per year; and     
     
  (3) costs paid to a dealer or other third party to repossess and preserve
      the manufactured home; and     
     
  (4) the amount of any sales commission paid to a dealer or other third
      party for the resale of the property; and     
     
  (5) for a land-and-home contract, property taxes, special assessments and
      other similar charges and hazard insurance premiums, prorated to the
      date of disposition of the property; and     
     
  (6) uncollected court costs; and     
     
  (7) legal fees, not to exceed $500; and     
     
  (8) expenses for recording the assignment of the lien on the collateral to
      the United States.     
   
    The insurance available to a lender under FHA Title I insurance is subject
to the limit of a reserve amount equal to ten percent of the original
principal balance of all Title I insured loans originated by the lender, which
amount is reduced by all claims paid to the lender and which is increased by
an amount equal to ten percent of the original principal balance of insured
loans subsequently originated by the lender. As of June 30, 1998, the
Company's Title I reserve amount was approximately $82,870,000, which amount
was available to pay claims in respect of approximately $895,090,000 of FHA-
insured home improvement loans and manufactured housing contracts serviced by
Green Tree. If Green Tree were replaced as servicer of the contracts under the
Agreement, it is not clear from the FHA regulations what portion of this
reserve amount would be available for claims for the FHA-insured contracts.
The obligation to pay insurance premiums to FHA is the obligation of Green
Tree, as servicer of the FHA-insured contracts.     
   
    The maximum guarantee that may be issued by the VA for a VA-guaranteed
contract is the lesser of (1) the lesser of $20,000 and 40% of the principal
amount of the contract and (2) the maximum amount of guaranty entitlement
available to the obligor veteran, which may range from $20,000 to zero. The
amount payable under the guarantee will be the percentage of the VA contract
originally guaranteed applied to indebtedness outstanding as of the applicable
date of computation specified in the VA regulations, interest accrued on the
unpaid balance of the loan to the appropriate date of computation and limited
expenses of the contract holder, but in each case only to the extent that the
amounts have not been recovered through resale of the manufactured home. The
amount payable under the guarantee may in no event exceed the amount of the
original guarantee.

                     CERTAIN LEGAL ASPECTS OF THE CONTRACTS
   
    The following discussion contains summaries of certain legal aspects of
manufactured housing contracts, including land-and-home contracts, which are
general in nature. Because these legal aspects are governed by applicable state
law, and these laws may differ substantially, the summaries do not purport to
be complete nor to reflect the laws of any particular state, nor to encompass
the laws of all states in which the security for the contracts or land-and-home
contracts is situated. The summaries are qualified in their entirety by
reference to the applicable federal and state laws governing the contracts or
land-and-home contracts.     
 
The Contracts (Other than Land-and-Home Contracts)
   
    General. As a result of the assignment of the contracts to the trustee, the
trust fund will succeed collectively to all of the rights, including the right
to receive payment on the contracts, and will assume the obligations of the
obligee under the contracts. Each contract evidences both (1) the obligation of
the obligor to repay the loan evidenced by the contract, and (2) the grant of a
security interest in the manufactured home to secure repayment of the loan.
Aspects of both features of the contracts are described more fully in this
section below.     
   
    The contracts generally are "chattel paper" as defined in the UCC in effect
in the states in which the manufactured homes initially were registered. Under
the UCC, the sale of chattel paper is treated in a manner similar to perfection
of a security interest in chattel paper. Under the pooling and servicing
agreement, Green Tree will retain possession of the contracts as custodian for
the trustee, and will make an appropriate filing of a UCC-1 financing statement
in Minnesota to give notice of the trustee's ownership of the contracts. The
contracts will be stamped to reflect their assignment from Green Tree to the
trustee. However, if through negligence, fraud or otherwise, a subsequent
purchaser were able to take physical possession of the contracts without notice
of the assignment, the trustee's interest in the contracts could be defeated.
       
    Security Interests in the Manufactured Homes. The manufactured homes
securing the contracts may be located in all 50 states and the District of
Columbia. Security interests in manufactured homes may be perfected either by
notation of the secured party's lien on the certificate of title or by delivery
of the required documents and payment of a fee to the state motor vehicle
authority, depending on state law. In some nontitle states, perfection pursuant
to the provisions of the UCC is required. Green Tree effects the notation or
delivery of the required documents and fees, and obtains possession of the
certificate of title, as appropriate, under the laws of the state in which a
manufactured home is registered. If Green Tree fails, due to clerical errors,
to effect this notation or delivery, or files the security interest under the
wrong law (for example, under a motor vehicle title statute rather than under
the UCC, in a few states), the certificateholders may not have a first priority
security interest in the manufactured home securing a contract. As manufactured
homes have become larger and often have been attached to their sites without
any apparent intention to move them, courts in many states have held that
manufactured homes, under certain circumstances, may     
 
                                       35
<PAGE>
 
   
become subject to real estate title and recording laws. As a result, a security
interest in a manufactured home could be rendered subordinate to the interests
of other parties claiming an interest in the home under applicable state real
estate law. In order to perfect a security interest in a manufactured home
under real estate laws, the holder of the security interest must file either a
"fixture filing" under the provisions of the UCC or a real estate mortgage
under the real estate laws of the state where the home is located. See "Land-
and-Home Contracts" below. These filings must be made in the real estate
records office of the county where the home is located. Substantially all of
the contracts contain provisions prohibiting the borrower from permanently
attaching the manufactured home to its site. So long as the borrower does not
violate this agreement, a security interest in the manufactured home will be
governed by the certificate of title laws or the UCC, and the notation of the
security interest on the certificate of title or the filing of a UCC financing
statement will be effective to maintain the priority of the security interest
in the manufactured home. If, however, a manufactured home becomes permanently
attached to its site, other parties could obtain an interest in the
manufactured home which is prior to the security interest originally retained
by the seller and transferred to Green Tree. Green Tree will represent that at
the date of the initial issuance of the related certificates it has obtained a
perfected first priority security interest by proper notation or delivery of
the required documents and fees with respect to substantially all of the
manufactured homes securing the contracts.     
   
    Green Tree will assign the security interest in the manufactured homes to
the trustee on behalf of the certificateholders. Unless otherwise specified in
the related prospectus supplement, neither Green Tree nor the trustee will
amend the certificates of title to identify the trustee as the new secured
party, and neither Green Tree nor the servicer will deliver the certificates of
title to the trustee or note the interest of the trustee. Accordingly, Green
Tree will continue to be named as the secured party on the certificates of
title relating to the manufactured homes. In some states, the assignment is an
effective conveyance of the security interest without amendment of any lien
noted on the related certificate of title and the new secured party succeeds to
the servicer's rights as the secured party. However, in some states in the
absence of an amendment to the certificate of title, the assignment of the
security interest in the manufactured home may not be held effective or the
security interests may not be perfected and in the absence of the notation or
delivery to the trustee, the assignment of the security interest in the
manufactured home may not be effective against creditors of Green Tree or a
trustee in bankruptcy of Green Tree.     
   
    In the absence of fraud, forgery or permanent affixation of the
manufactured home to its site by the manufactured home owner, or administrative
error by state recording officials, the notation of the lien of Green Tree on
the certificate of title or delivery of the required documents and fees will be
sufficient to protect the certificateholders against the rights of subsequent
purchasers of a manufactured home or subsequent lenders who take a security
interest in the manufactured home. If there are any manufactured homes as to
which Green Tree's security interest is not perfected, the security interest
would be subordinate to, among others, subsequent purchasers for value of the
manufactured homes and holders of perfected security interests. There also
exists a risk in not identifying the trustee as the new secured     
 
                                       36
<PAGE>
 
   
party on the certificate of title that, through fraud or negligence, the
security interest of the trustee could be released.     
   
    If the owner of a manufactured home moves it to a state other than the
state in which the manufactured home initially is registered, under the laws of
most states the perfected security interest in the manufactured home would
continue for four months after the relocation and thereafter only if and after
the owner re-registers the manufactured home in that state. If the owner were
to relocate a manufactured home to another state and not re-register the
manufactured home in that state, and if steps were not taken to re-perfect the
trustee's security interest in that state, the security interest in the
manufactured home would cease to be perfected. A majority of states generally
require surrender of a certificate of title to re-register a manufactured home;
accordingly, Green Tree must surrender possession if it holds the certificate
of title to the manufactured home or, in the case of manufactured homes
registered in states which provide for notation of lien, Green Tree would
receive notice of surrender if the security interest in the manufactured home
is noted on the certificate of title. Accordingly, Green Tree would have the
opportunity to re-perfect its security interest in the manufactured home in the
state of relocation. In states which do not require a certificate of title for
registration of a manufactured home, re-registration could defeat perfection.
In the ordinary course of servicing the manufactured housing conditional sales
contracts, Green Tree takes steps to effect the re-perfection upon receipt of
notice of re-registration or information from the obligor as to relocation.
Similarly, when an obligor under a contract sells a manufactured home, Green
Tree must surrender possession of the certificate of title or will receive
notice as a result of its lien noted on the title and accordingly will have an
opportunity to require satisfaction of the related manufactured housing
conditional sales contract before release of the lien. Under the pooling and
servicing agreement, the servicer is obligated to take steps, at the servicer's
expense, necessary to maintain perfection of security interests in the
manufactured homes.     
   
    Under the laws of most states, liens for repairs performed on a
manufactured home and liens for personal property taxes take priority over a
perfected security interest. Green Tree will represent in the pooling and
servicing agreement that it has no knowledge of any liens on any manufactured
home securing payment on any contract. However, liens could arise at any time
during the term of a contract. No notice will be given to the trustee or
certificateholders if a lien arises.     
   
    Enforcement of Security Interests in Manufactured Homes. The servicer on
behalf of the trustee, as required by the related pooling and servicing
agreement, may take action to enforce the trustee's security interest on
contracts in default by repossession and resale of the manufactured homes
securing the defaulted contracts. So long as the manufactured home has not
become subject to real estate laws, a creditor can repossess a manufactured
home securing a contract by voluntary surrender, by "self-help" repossession
that is "peaceful" (i.e., without breach of the peace) or, in the absence of
voluntary surrender and the ability to repossess without breach of the peace,
by judicial process. The holder of a contract must give the debtor a number of
days' notice, which varies from 10 to 30 days depending on the state, before
commencement of any repossession. The UCC and consumer protection laws in     
 
                                       37
<PAGE>
 
   
most states place restrictions on repossession sales, including requiring prior
notice to the debtor and commercial reasonableness in effecting such a sale.
The law in most states also requires that the debtor be given notice of any
sale before resale of the unit so that the debtor may redeem at or before the
resale. In the event of such repossession and resale of a manufactured home,
the trustee would be entitled to be paid out of the sale proceeds before the
proceeds could be applied to the payment of the claims of unsecured creditors
or the holders of subsequently perfected security interests or, thereafter, to
the debtor.     
   
    Under the laws applicable in most states, a creditor is entitled to obtain
a deficiency judgment from a debtor for any deficiency on repossession and
resale of the manufactured home securing the debtor's loan. However, some
states impose prohibitions or limitations on deficiency judgments, and in many
cases the defaulting borrower would have no assets with which to pay a
judgment.     
 
    Certain other statutory provisions, including federal and state bankruptcy
and insolvency laws and general equitable principles, may limit or delay the
ability of a lender to repossess and resell collateral or enforce a deficiency
judgment.
   
    Under the terms of the federal Soldiers' and Sailors' Civil Relief Act of
1940, an obligor who enters military service after the origination of the
obligor's contract, including an obligor who is a member of the National Guard
or is in reserve status at the time of the origination of the contract and is
later called to active duty, may not be charged interest above an annual rate
of 6% during the period of the obligor's active duty status, unless a court
orders otherwise upon application of the lender. It is possible that the action
could have an effect, for an indeterminate period of time, on the ability of
the servicer to collect full amounts of interest on some of the contracts. Any
shortfall in interest collections resulting from the application of the Relief
Act, to the extent not covered by the subordination of a class of subordinated
certificates, could result in losses to the holders of a series of
certificates. In addition, the Relief Act imposes limitations which would
impair the ability of the servicer to foreclose on an affected contract during
the obligor's period of active duty status. Thus, if a contract goes into
default, there may be delays and losses occasioned by the inability to realize
upon the manufactured home in a timely fashion.     
 
Land-and-Home Contracts
   
    General. The land-and-home contracts will be secured by either first
mortgages or deeds of trust, depending upon the prevailing practice in the
state where the underlying property is located. A mortgage creates a lien upon
the real property described in the mortgage. There are two parties to a
mortgage: the mortgagor, who is the borrower, and the mortgagee, who is the
lender. In a mortgage state, the mortgagor delivers to the mortgagee a note or
bond evidencing the loan and the mortgage. Although a deed of trust is similar
to a mortgage, a deed of trust has three parties: the borrower, a lender as
beneficiary, and a third-party grantee called the trustee. Under a deed of
trust, the borrower grants the property, irrevocably until the debt is paid, in
trust, generally with a power of sale, to the trustee to secure payment of the
loan. The trustee's authority under a deed of trust and the mortgagee's     
 
                                       38
<PAGE>
 
authority under a mortgage are governed by the express provisions of the deed
of trust or mortgage, applicable law, and, in some cases, with respect to the
deed of trust, the directions of the beneficiary.
   
    Foreclosure. Foreclosure of a mortgage is generally accomplished by
judicial action. Generally, the action is initiated by the service of legal
pleadings upon all parties having an interest of record in the real property.
Delays in completion of the foreclosure occasionally may result from
difficulties in locating necessary parties defendant. When the mortgagee's
right to foreclosure is contested, the legal proceedings necessary to resolve
the issue can be time-consuming and expensive. After the completion of a
judicial foreclosure proceeding, the court may issue a judgment of foreclosure
and appoint a receiver or other officer to conduct the sale of the property. In
some states, mortgages may also be foreclosed by advertisement, under a power
of sale provided in the mortgage. Foreclosure of a mortgage by advertisement is
essentially similar to foreclosure of a deed of trust by non-judicial power of
sale.     
   
    Foreclosure of a deed of trust is generally accomplished by a non-judicial
trustee's sale under a specific provision in the deed of trust that authorizes
the trustee to sell the property to a third party upon any default by the
borrower under the terms of the note or deed of trust. In some states, the
foreclosure also may be accomplished by judicial action in the manner provided
for foreclosure of mortgages. In some states the trustee must record a notice
of default and send a copy to the borrower-trustor and to any person who has
recorded a request for a copy of a notice of default and the notice of sale. In
addition, the trustee must provide notice in some states to any other
individual having an interest of record in the real property, including any
junior lienholders. If the deed of trust is not reinstated within any
applicable cure period, a notice of sale must be posted in a public place and,
in most states, published for a specified period of time in one or more
newspapers. In addition, some state laws require that a copy of the notice of
sale be posted on the property and sent to all parties having an interest of
record in the property.     
 
    In some states, the borrower-trustor has the right to reinstate the loan at
any time following default until shortly before the trustee's sale. In general,
the borrower, or any other person having a junior encumbrance on the real
estate, may, during a reinstatement period, cure the default by paying the
entire amount in arrears plus the costs and expenses incurred in enforcing the
obligation. Certain state laws control the amount of foreclosure expenses and
costs, including attorneys' fees, that may be recovered by a lender.
 
    In the case of foreclosure under either a mortgage or a deed of trust, the
sale by the receiver or other designated officer, or by the trustee, is a
public sale. However, because of the difficulty a potential buyer at the sale
would have in determining the exact status of title and because the physical
condition of the property may have deteriorated during the foreclosure
proceedings, it is not common for a third party to purchase the property at the
foreclosure sale. Rather, the lender generally purchases the property from the
trustee or receiver for an amount equal to the unpaid principal amount of the
note, accrued and unpaid interest and the expenses of foreclosure. Thereafter,
subject to the right of the borrower in
 
                                       39

some states to remain in possession during the redemption period, the lender
will assume the burdens of ownership, including obtaining hazard insurance and
making such repairs at its own expense as are necessary to render the property
suitable for sale. The lender commonly will obtain the services of a real
estate broker and pay the broker a commission in connection with the sale of
the property. Depending upon market conditions, the ultimate proceeds of the
sale of the property may not equal the lender's investment in the property.
   
    Rights of Redemption. In some states, after sale under a deed of trust or
foreclosure of a mortgage, the borrower and foreclosed junior lienors are given
a statutory period in which to redeem the property from the foreclosure sale.
In other states, this right of redemption applies only to sale following
judicial foreclosure, and not sale pursuant to a non-judicial power of sale. In
most states where the right of redemption is available, statutory redemption
may occur upon payment of the foreclosure purchase price, accrued interest and
taxes. In some states the right to redeem is an equitable right. The effect of
a right of redemption is to diminish the ability of the lender to sell the
foreclosed property. The exercise of a right of redemption would defeat the
title of any purchaser at a foreclosure sale, or of any purchaser from the
lender subsequent to judicial foreclosure or sale under a deed of trust.
Consequently, the practical effect of the redemption right is to force the
lender to maintain the property and pay the expenses of ownership until the
redemption period has run.     
   
    Anti-Deficiency Legislation and Other Limitations on Lenders. Some states
have imposed statutory restrictions that limit the remedies of a beneficiary
under a deed of trust or a mortgagee under a mortgage relating to a single
family residence. In some states, statutes limit the right of the beneficiary
or mortgagee to obtain a deficiency judgment against the borrower following
foreclosure or sale under a deed of trust. A deficiency judgment is a personal
judgment against the borrower equal in most cases to the difference between the
amount due to the lender and the net amount realized upon the foreclosure sale.
       
    Some state statutes may require the beneficiary or mortgagee to exhaust the
security afforded under a deed of trust or mortgage by foreclosure in an
attempt to satisfy the full debt before bringing a personal action against the
borrower. In other states, the lender has the option of bringing a personal
action against the borrower on the debt without first exhausting the security;
however, in some of these states, the lender, following judgment on the
personal action, may be deemed to have elected a remedy and may be precluded
from exercising remedies on the security. Consequently, the practical effect of
the election requirement, when applicable, is that lenders will usually proceed
first against the security rather than bringing a personal action against the
borrower.     
   
    Other statutory provisions may limit any deficiency judgment against the
former borrower following a foreclosure sale to the excess of the outstanding
debt over the fair market value of the property at the time of the sale. The
purpose of these statutes is to prevent a beneficiary or a mortgagee from
obtaining a large deficiency judgment against the former borrower as a result
of low or no bids at the foreclosure sale.     
 
 
                                       40
<PAGE>
 
    In some states, exceptions to the anti-deficiency statutes are provided for
in certain instances where the value of the lender's security has been impaired
by acts or omissions of the borrower, for example, in the event of waste of the
property.
   
    In addition to anti-deficiency and related legislation, numerous other
federal and state statutory provisions, including the federal bankruptcy laws,
the federal Soldiers' and Sailors' Civil Relief Act of 1940 and state laws
affording relief to debtors, may interfere with or affect the ability of a
secured mortgage lender to realize upon its security. For example, with respect
to a land-and-home contract, in a Chapter 13 proceeding under the federal
Bankruptcy Code, when a court determines that the value of a home is less than
the principal balance of the loan, the court may prevent a lender from
foreclosing on the home, and, as part of the rehabilitation plan, reduce the
amount of the secured indebtedness to the value of the home as it exists at the
time of the proceeding, leaving the lender as a general unsecured creditor for
the difference between that value and the amount of outstanding indebtedness. A
bankruptcy court may grant the debtor a reasonable time to cure a payment
default, and in the case of a mortgage loan not secured by the debtor's
principal residence, also may reduce the monthly payments due under the
mortgage loan, change the rate of interest and alter the mortgage loan
repayment schedule. Certain court decisions have applied such relief to claims
secured by the debtor's principal residence.     
   
    The Code provides priority to certain tax liens over the lien of the
mortgage or deed of trust. The laws of some states provide priority to certain
tax liens over the lien of the mortgage or deed of trust. Numerous federal and
some state consumer protection laws impose substantive requirements upon
mortgage lenders in connection with the origination, servicing and the
enforcement of mortgage loans. These laws include the federal Truth in Lending
Act, Real Estate Settlement Procedures Act, Equal Credit Opportunity Act, Fair
Credit Billing Act, Fair Credit Reporting Act, and related statutes and
regulations. These federal laws and state laws impose specific statutory
liabilities upon lenders who originate or service mortgage loans and who fail
to comply with the provisions of the law. In some cases, this liability may
affect assignees of the contracts.     
       
Consumer Protection Laws
   
    The so-called "holder-in-due-course" rule of the Federal Trade Commission
is intended to defeat the ability of the transferor of a consumer credit
contract which is the seller of goods which gave rise to the transaction and
related lenders and assignees, to transfer the contract free of notice of
claims by the debtor. The effect of this rule is to subject the assignee of the
contract, such as the trust fund, to all claims and defenses which the obligor
could assert against the seller of the manufactured home. Liability under this
rule is limited to amounts paid under a contract; however, the obligor also may
be able to assert the rule to set off remaining amounts due as a defense
against a claim brought by the trust fund against the obligor. Numerous other
federal and state consumer protection laws impose requirements applicable to
the origination and lending under the contracts, including the Truth in Lending
Act, the Federal Trade Commission Act, the Fair Credit Billing Act, the Fair
Credit Reporting Act, the Equal Credit Opportunity Act, the Fair Debt
Collection     
 
                                       41
<PAGE>
 
   
Practices Act and the Uniform Consumer Credit Code. In the case of some of
these laws, the failure to comply with their provisions may affect the
enforceability of the related contract.     
 
Transfers of Manufactured Homes; Enforceability of "Due-on-Sale" Clauses
   
    The contracts, in general, prohibit the sale or transfer of the related
manufactured homes without the consent of the servicer and permit the
acceleration of the maturity of the contracts by the servicer upon any sale or
transfer that is not consented to. Green Tree expects that it will permit most
transfers of manufactured homes and not accelerate the maturity of the related
contracts. In certain cases, the transfer may be made by a delinquent Obligor
in order to avoid a repossession proceeding on a manufactured home.     
   
    In the case of a transfer of a manufactured home after which the servicer
desires to accelerate the maturity of the related contract, the servicer's
ability to do so will depend on the enforceability under state law of the "due-
on-sale" clause. The Garn-St. Germain Depositary Institutions Act of 1982
preempts, subject to exceptions and conditions, state laws prohibiting
enforcement of "due-on-sale" clauses applicable to the manufactured homes.
Consequently, in some states the servicer may be prohibited from enforcing a
"due-on-sale" clause on some manufactured homes.     
 
Applicability of Usury Laws
   
    Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, provides that, subject to the following conditions, state usury
limitations shall not apply to any loan which is secured by a first lien on
certain kinds of manufactured housing. The contracts would be covered if they
satisfy certain conditions governing the terms of any prepayments, late charges
and deferral fees and requiring a 30-day notice period before instituting any
action leading to repossession of or foreclosure on to the related unit.     
   
    Title V authorized any state to reimpose limitations on interest rates and
finance charges by adopting before April 1, 1983 a law or constitutional
provision which expressly rejects application of the federal law. Fifteen
states adopted such a law prior to the April 1, 1983 deadline. In addition,
even where Title V was not rejected, any state is authorized by the law to
adopt a provision limiting discount points or other charges on loans covered by
Title V. Green Tree will represent in the applicable Agreement that all of the
contracts comply with applicable usury law.     
 
                              ERISA CONSIDERATIONS
   
    The Employee Retirement Income Security Act of 1974 imposes requirements on
employee benefit plans subject to ERISA ("Plans") and on persons who are
fiduciaries with respect to such Plans. Generally, ERISA applies to investments
made by such Plans. Among other requirements, ERISA mandates that the assets of
Plans be held in trust and that the trustee, or other duly authorized
fiduciary, have exclusive authority and discretion to manage and control the
assets of those Plans. ERISA also imposes duties on persons who are     
 
                                       42
<PAGE>
 
   
fiduciaries of the Plans. Under ERISA, and subject to exemptions not relevant
to this offering, any person who exercises any authority or control over the
management or disposition of the assets of a Plan is considered to be a
fiduciary of the Plan, subject to the standards of fiduciary conduct under
ERISA. These standards include the requirements that the assets of Plans be
invested and managed for the exclusive benefit of Plan participants and
beneficiaries, a determination by the Plan fiduciary that any such investment
is permitted under the governing Plan instruments and is prudent and
appropriate for the Plan in view of its overall investment policy and the
composition and diversification of its portfolio. Some employee benefit plans,
such as governmental plans (as defined in ERISA Section 3(32)) and certain
church plans (as defined in ERISA Section 3(33)), are not subject to ERISA.
Accordingly, assets of these plans may be invested in certificates without
regard to the ERISA considerations described above and in the paragraphs below,
subject to the provisions of applicable state law. Any plan which is qualified
and exempt from taxation under Sections 401(a) and 501(a) of the Internal
Revenue Code of 1986, however, is subject to the prohibited transaction rules
provided in Section 503 of the Code.     
   
    In addition to the imposition of general fiduciary standards of investment
prudence and diversification, ERISA, and the corresponding provisions of the
Code, prohibit a broad range of transactions involving Plan assets and persons
having specified relationships to a Plan ("parties in interest" within the
meaning of ERISA, and "disqualified persons" within the meaning of ERISA).
These transactions are treated as "prohibited transactions" under Sections 406
and 407 of ERISA and excise taxes are imposed upon such persons by Section 4975
of the Code. An investment in the certificates by a Plan might constitute
prohibited transactions under the foregoing provisions unless an administrative
exemption applies. In addition, if an investing Plan's assets were deemed to
include an interest in the assets of the contract pool and not merely an
interest in the certificates, transactions occurring in the operation of the
contract pool might constitute prohibited transactions unless an administrative
exemption applies. Certain such exemptions which may be applicable to the
acquisition and holding of the certificates or to the servicing and operation
of the contract pool are noted in the paragraphs below.     
   
    The Department of Labor has issued a regulation (29 C.F.R. Section 2510.3-
101) concerning the definition of what constitutes the assets of a Plan. This
regulation provides that, as a general rule, the underlying assets and
properties of corporations, partnerships, trusts and certain other entities in
which a Plan makes an "equity" investment will be deemed for purposes of ERISA
to be assets of the investing plan unless certain exceptions apply. However,
the regulation provides that, generally, the assets of a corporation or
partnership in which a Plan invests will not be deemed for purposes of ERISA to
be assets of such Plan if the equity interest acquired by the investing Plan is
a publicly-offered security. A publicly-offered security, as defined under the
regulation, is a security that is widely held, freely transferable, and
registered under the Securities Exchange Act of 1934. The certificates are not
expected to be publicly-offered securities under the terms of this regulation.
    
                                       43
<PAGE>
 
   
    Relief from the prohibited transaction rules of Section 406 and 407 of
ERISA (and from the prohibited transaction excise tax provisions of Section
4975 of the Code) may be found under the provisions of specific statutory or
administrative exemptive relief authorized under Section 408 of ERISA. In
Prohibited Transaction Exemption 83-1 ("PTE 83-1"), which amended Prohibited
Transaction Exemption 81-7, the DOL exempted from ERISA's prohibited
transaction rules transactions relating to the operation of residential
mortgage pool investment trusts and the purchase, sale and holding of "mortgage
pool pass-through certificates" in the initial issuance of such certificates.
PTE 83-1 permits, subject to certain conditions, transactions which might
otherwise be prohibited between Plans and parties in interest with respect to
those Plans related to the origination, maintenance and termination of mortgage
pools consisting of mortgage loans secured by first or second mortgages or
deeds of trust on single-family residential property, and the acquisition and
holding of certain mortgage pool pass-through certificates representing an
interest in such mortgage pools by Plans. If the general conditions of PTE 83-1
are satisfied, investments by a Plan in certificates that represent interests
in a mortgage pool consisting of single family loans will be exempt from the
prohibitions of Sections 406(a) and 407 of ERISA (relating generally to
transactions with parties in interest who are not fiduciaries) if the Plan
purchases such certificates at no more than fair market value, and will be
exempt from the prohibitions of Section 406(b)(1) and (2) of ERISA (relating
generally to transactions with fiduciaries) if, in addition, the purchase is
approved by an independent fiduciary, no sales commission is paid to the pool
sponsor, the Plan does not purchase more than 25 percent of such certificates,
and at least 50 percent of all such certificates are purchased by persons
independent of the pool sponsor or pool trustee. However, PTE 83-1 does not
provide an exemption for transactions involving subordinate certificates or for
certificates representing an interest in conditional sales contracts and
installment sales or loan agreements secured by manufactured housing like the
contracts.     
   
    We cannot assure you that any of the exceptions provided in the regulation
described in the paragraph above, PTE 83-1 or any other administrative
exemption under ERISA, will apply to the purchase of certificates offered under
this prospectus, and, as a result, an investing Plan's assets could be
considered to include an undivided interest in the manufactured housing
contracts and any other assets held in the contract pool. If the assets of a
contract pool are considered assets of an investing Plan, Green Tree, the
servicer, the trustee and other persons, in providing services on the
contracts, may be considered fiduciaries to the Plan and subject to the
fiduciary responsibility provisions of Title I of ERISA and the prohibited
transaction provisions of Section 4975 of the Code for transactions involving
those assets unless a statutory or administrative exemption applies.     
   
    Any Plan fiduciary considering the purchase of a certificate should consult
with its counsel about the potential applicability of ERISA and the Code to the
investment. Moreover, each Plan fiduciary should determine whether, under the
general fiduciary standards of investment prudence and diversification, an
investment in the certificates is appropriate for the Plan, taking into account
the overall investment policy of the Plan and the composition of the Plan's
investment portfolio.

    PTE 95-60 exempts from ERISA's prohibited transaction rules transactions
engaged in by insurance company general accounts in which an employee benefit
plan has an interest if specified conditions are met. Additional exemptive
relief is provided for plans to engage in transactions with persons who provide
services to insurance company general accounts. PTE 95-60 also permits
transactions relating to the origination and operation of asset pool investment
trusts in which an insurance company general account has an interest as the
result of the acquisition of certificates issued by the trust.     
   
    PTE 95-60 will provide an exemption for transactions involving certificates
representing interests in asset-backed pass-through trusts that consist of
certain receivables, loans and other obligations that meet the conditions and
requirements of PTE 95-60. The receivables covered by PTE 95-60 include
manufactured housing installment sale contracts and installment loan agreements
such as the manufactured housing contracts. The exemption offered by PTE 95-60
is conditioned upon compliance with the requirements of one of several
"underwriter exemptions," other than compliance with the requirements that the
certificates acquired by the general account not be subordinated and receive a
rating that is in one of the three highest generic rating categories from
either S&P, Moody's, Duff & Phelps Credit Rating Co. or Fitch.     
   
    In addition to any exemption that may be available under PTCE 95-60 for the
purchase and holding of the certificates by an insurance company general
account, the Small Business Job Protection Act of 1996 added a new Section
401(c) to ERISA, which provides exemptive relief from the provisions of Part 4
of Title I of ERISA and Section 4975 of the Code, including the prohibited
transaction restrictions imposed by ERISA and the related excise taxes imposed
by the Code, for transactions involving an insurance company general account.
Under Section 401(c) of ERISA, the DOL published proposed regulations
("Proposed 401(c) Regulations") on December 22, 1997 to provide guidance for
the purpose of determining, in cases where insurance policies supported by an
insurer's general account are issued to or for the benefit of a Plan on or
before December 31, 1998, which general account assets constitute Plan assets.
Section 401(c) of ERISA generally provides that, until the date which is 18
months after the Proposed 401(c) Regulations become final, no person will be
subject to liability under Part 4 of Title I of ERISA and Section 4975 of the
Code on the basis of a claim that the assets of an insurance company general
account constitute Plan assets, unless     
       
    (1) as otherwise provided by the Secretary of Labor in the Proposed
        401(c) Regulations to prevent avoidance of the regulations; or     
       
    (2) an action is brought by the Secretary of Labor for breaches of
        fiduciary duty which would also constitute a violation of federal or
        state criminal law.     
   
Any assets of an insurance company general account which support insurance
policies issued to a Plan after December 31, 1998 or issued to Plans on or
before December 31, 1998 for which the insurance company does not comply with
the Proposed 401(c) Regulations may be treated as Plan assets. In addition,
because Section 401(c) does not relate to insurance     
 
                                       45
<PAGE>
 
   
company separate accounts, separate account assets are still treated as Plan
assets of any Plan invested in the separate account. Insurance companies
contemplating the investment of general account assets in the certificates
should consult with their legal counsel about the applicability of PTCE 95-60
and Section 401(c) of ERISA, including the general account's ability to
continue to hold the securities after the date which is 18 months after the
date the Proposed 401(c) Regulations become final.     
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
General
   
    The following is a general discussion of certain federal income tax
consequences relating to the purchase, ownership, and disposition of the
certificates. The discussion is based upon laws, regulations, rulings, and
decisions now in effect, including Treasury Regulations issued on December 23,
1992, and generally effective for REMICs with startup days on or after November
12, 1991, all of which are subject to change or possibly differing
interpretations. The discussion does not purport to deal with federal income
tax consequences applicable to all categories of investors, some of which may
be subject to special rules. Investors should consult their own tax advisors to
determine the federal, state, local, and any other tax consequences of the
purchase, ownership, and disposition of the certificates.     
   
    Many aspects of the federal tax treatment of the purchase, ownership, and
disposition of the certificates will depend upon whether an election is made to
treat the Trust Fund or a segregated portion thereof evidenced by a particular
series or sub-series of certificates as a REMIC within the meaning of Section
860D(a) of the Internal Revenue Code of 1986. The prospectus supplement for
each series will indicate whether or not an election to be treated as a REMIC
has been or will be made with respect thereto. The following discussion deals
first with series for which a REMIC election is made and then with series for
which a REMIC election is not made.     
 
REMIC Series
   
    For each series of certificates for which a REMIC election is made, counsel
to Green Tree identified in the applicable prospectus supplement will have
advised Green Tree that in its opinion, assuming (1) the making of that
election in accordance with the requirements of the Code and (2) ongoing
compliance with the applicable Agreement, at the initial issuance of the
certificates in the series the trust fund will qualify as a REMIC and the
certificates in that series ("REMIC Certificates") will be treated either as
regular interests in the REMIC within the meaning of Section 860G(a)(1) of the
Code ("Regular Certificates") or as residual interests in the REMIC within the
meaning of Section 860G(a)(2) of the Code ("Residual Certificates").     
   
    Qualification as a REMIC. Qualification as a REMIC involves ongoing
compliance with requirements and the following discussion assumes that these
requirements will be     
 
                                       46
<PAGE>
 
   
satisfied by the Trust Fund so long as there are any REMIC certificates
outstanding. Substantially all of the assets of the REMIC must consist of
"qualified mortgages" and "permitted investments" as of the close of the third
month beginning after the day on which the REMIC issues all of its regular and
residual interests (the "startup day") and at all times thereafter. The term
"qualified mortgage" means any obligation, including a participation or
certificate of beneficial ownership in that obligation, which is principally
secured by an interest in real property that is transferred to the REMIC on the
startup day in exchange for regular or residual interests in the REMIC or is
purchased by the REMIC within the three-month period beginning on the startup
day if the purchase is under a fixed price contract in effect on the startup
day. The REMIC regulations provide that a contract is principally secured by an
interest in real property if the fair market value of the real property
securing the contract is at least equal to either (1) 80% of the issue price
(generally, the principal balance) of the contract at the time it was
originated or (2) 80% of the adjusted issue price (the then-outstanding
principal balance, with adjustments) of the contract at the time it is
contributed to a REMIC. The fair market value of the underlying real property
is to be determined after taking into account other liens encumbering that real
property. Alternatively, a contract is principally secured by an interest in
real property if substantially all of the proceeds of the contract were used to
acquire or to improve or protect an interest in real property that, at the
origination date, is the only security for the contract (other than the
personal liability of the obligor). The REMIC regulations provide that
obligations secured by manufactured housing or mobile homes (not including
recreational vehicles, campers or similar vehicles) which are "single family
residences" under Section 25(e)(10) of the Code will qualify as obligations
secured by real property without regard to state law classifications. See the
discussion below under "REMIC Series--Status of Manufactured Housing
Contracts." A qualified mortgage also includes a qualified replacement mortgage
that is used to replace any qualified mortgage within three months of the
startup day or to replace a defective mortgage within two years of the startup
day.     
       
    "Permitted investments" consist of:     
     
  .  temporary investments of cash received under qualified mortgages before
     distribution to holders of interests in the REMIC ("cash-flow
     investments"),     
     
  .  amounts, such as a Reserve Fund, if any, reasonably required to provide
     for full payment of expenses of the REMIC, the principal and interest
     due on regular or residual interests in the event of defaults on
     qualified mortgages, lower than expected returns on cash-flow
     investments, prepayment interest shortfalls or other contingencies
     ("qualified reserve assets"), and     
     
  .  property acquired as a result of foreclosure of defaulted qualified
     mortgages ("foreclosure property").     
   
A reserve fund will not be qualified if more than 30% of the gross income from
the assets in the reserve fund is derived from the sale or other disposition of
property held for three months or less, unless the sale is necessary to prevent
a default in payment of principal or interest on Regular Certificates. In
accordance with Section 860G(a)(7) of the Code, a     
 
                                       47
<PAGE>
 
   
reserve fund must be "promptly and appropriately" reduced as payments on
contracts are received. Foreclosure property will be a permitted investment
only to the extent that the property is not held for more than two years.     
   
    The Code requires that in order to qualify as a REMIC an entity must make
reasonable arrangements designed to ensure that specified entities, generally
including governmental entities or other entities that are exempt from United
States tax, including the tax on unrelated business income ("disqualified
organizations"), not hold residual interests in the REMIC. Consequently, it is
expected that in the case of any Trust Fund for which a REMIC election is made
the transfer, sale, or other disposition of a Residual Certificate to a
disqualified organization will be prohibited and the ability of a Residual
Certificate to be transferred will be conditioned on the trustee's receipt of a
certificate or other document representing that the proposed transferee is not
a disqualified organization. The transferor of a Residual Certificate must not,
as of the time of the transfer, have actual knowledge that the representation
is false. The Code further requires that reasonable arrangements must be made
to enable a REMIC to provide the Internal Revenue Service and certain other
parties, including transferors of residual interests in a REMIC, with the
information needed to compute the tax imposed by Section 860E(e)(1) of the Code
if, in spite of the steps taken to prevent disqualified organizations from
holding residual interests, such an organization does, in fact, acquire a
residual interest. See "REMIC Series--Restrictions on Transfer of Residual
Certificates" below.     
   
    If the trust fund fails to comply with one or more of the ongoing
requirements for qualification as a REMIC, the trust fund will not be treated
as a REMIC for the year during which the failure occurs and thereafter unless
the IRS determines, in its discretion, that the failure was inadvertent (in
which case, the IRS may require any adjustments which it deems appropriate). If
the ownership interests in the assets of the trust fund consist of multiple
classes, failure to treat the trust fund as a REMIC may cause the trust fund to
be treated as an association taxable as a corporation. This treatment could
result in income of the trust fund being subject to corporate tax in the hands
of the trust fund and in a reduced amount being available for distribution to
certificateholders as a result of the payment of the taxes.     
   
    Status of Manufactured Housing Contracts. The REMIC regulations as well as
a notice issued by the IRS provide that obligations secured by interests in
manufactured housing, which qualify as "single family residences" within the
meaning of Section 25(e)(10) of the Code, are to be treated as "qualified
mortgages" for a REMIC. Under Section 25(e)(10) of the Code, the term "single
family residence" includes any manufactured home which has a minimum of 400
square feet of living space and a minimum width in excess of 102 inches and
which is of a kind customarily used at a fixed location. Green Tree will
represent and warrant that each of the manufactured homes securing the
contracts which are a part of a trust fund meets this definition of a "single
family residence." See the discussion above under "REMIC Series--Qualification
as a REMIC."     
   
    Two-Tier REMIC Structures. For certain series of certificates, two separate
elections may be made to treat segregated portions of the assets of a single
Trust Fund as REMICs for     
 
                                       48
<PAGE>
 
   
federal income tax purposes (respectively, the "Subsidiary REMIC" and the
"Master REMIC"). Upon the issuance of any such series of certificates, counsel
will have advised Green Tree, as described above, that at the initial issuance
of the certificates, the Subsidiary REMIC and the Master REMIC will each
qualify as a REMIC for federal income tax purposes, and that the certificates
in that a series will be treated either as Regular Certificates or Residual
Certificates of the appropriate REMIC. Only REMIC Certificates issued by the
Master REMIC will be offered under this prospectus. Solely for the purpose of
determining whether the regular certificates will constitute qualifying real
estate or real property assets for certain categories of financial institutions
or real estate investment trusts as described below, both REMICs in a two-tier
REMIC structure will be treated as one. See the discussion below under "REMIC
Series--Taxation of Regular Interests."     
   
    Taxation of Regular Interests. Regular Certificates will be treated as new
debt instruments issued by the REMIC on the startup day. If a Regular
Certificate represents an interest in a REMIC that consists of a specified
portion of the interest payments on the REMIC's qualified mortgages, the stated
principal amount for that Regular Certificate may be zero. Such a specified
portion may consist of a fixed number of basis points, a fixed percentage of
interest or a qualified variable rate on some or all of the qualified
mortgages. Stated interest on a regular certificate will be taxable as ordinary
income. Holders of Regular Certificates that would otherwise report income
under a cash method of accounting will be required to report income on these
Regular Certificates under the accrual method. Under temporary treasury
regulations, if a trust fund, with respect to which a REMIC election is made,
is considered to be a "single-class REMIC," a portion of the REMIC's servicing
fees, administrative and other non-interest expenses, including assumption fees
and late payment charges retained by Green Tree, will be allocated as a
separate item to those Regular Certificateholders that are "pass-through
interest holders." Generally, a single-class REMIC is defined as a REMIC that
would be treated as a fixed investment trust under applicable law but for its
qualification as a REMIC, or a REMIC that is substantially similar to an
investment trust but is structured with the principal purpose of avoiding this
allocation requirement imposed by the temporary treasury regulations.
Generally, a pass-through interest holder refers to individuals, entities taxed
as individuals, such as certain trusts and estates, and regulated investment
companies. An individual, an estate, or a trust that holds a Regular
Certificate in the REMIC will be allowed to deduct the foregoing expenses under
Section 212 of the Code only to the extent that, in the aggregate and combined
with certain other itemized deductions, they exceed 2% of the adjusted gross
income of the holder. In addition, Section 68 of the Code provides that the
amount of itemized deductions (including those provided for in Section 212 of
the Code) otherwise allowable for the taxable year for an individual whose
adjusted gross income exceeds a threshold amount specified in the Code
($124,500 in 1998 in the case of a joint return) will be reduced by the lesser
of (1) 3% of the excess of adjusted gross income over the specified threshold
amount or (2) 80% of the amount of itemized deductions otherwise allowable for
such taxable year. As a result of these limitations, certain holders of regular
certificates in "single-class REMICs" may not be entitled to deduct all or any
part of these expenses.

    Tax Status of REMIC Certificates. In general, (1) Regular Certificates held
by a thrift institution taxed as a "domestic building and loan association"
within the meaning of Section 7701(a)(19) of the Code will constitute "a
regular ... interest in a REMIC" within the meaning of Section
7701(a)(19)(C)(xi) of the Code; and (2) Regular Certificates held by a real
estate investment trust will constitute "real estate assets" within the meaning
of Section 856(c)(4)(A) of the Code and interest thereon will be considered
"interest on obligations secured by mortgages on real property" within the
meaning of Section 856(c)(3)(B) of the Code. If less than 95% of the average
adjusted basis of the assets comprising the REMIC are assets qualifying under
any of the foregoing Sections of the Code (including assets described in
Section 7701(a)(19)(C) of the Code), then the Regular Certificates will be
qualifying assets only to the extent that the assets comprising the REMIC are
qualifying assets. Section 7701(a)(19)(C)(v) of the Code provides that "loans
secured by an interest in real property" includes loans secured by mobile homes
not used on a transient basis. Treasury regulations promulgated under Section
856 of the Code state that local law definitions are not controlling in
determining the meaning of the term "real property" for purposes of that
section, and the IRS has ruled that obligations secured by permanently
installed mobile home units qualify as "real estate assets" under this
provision. Furthermore, interest paid with respect to certificates held by a
real estate investment trust will be considered "interest on obligations
secured by mortgages on real property or on interests in real property" within
the meaning of Section 856(c)(3)(B) of the Code to the same extent that the
certificates themselves are treated as real estate assets. Regular Certificates
held by a regulated investment company or a real estate investment trust will
not constitute "Government securities" within the meaning of Sections
851(b)(4)(A)(i) and 856(c)(5)(A) of the Code, respectively. In addition, the
REMIC regulations provide that payments on contracts held and reinvested
pending distribution to certificateholders will be considered to be "real
estate assets" within the meaning of Section 856(c)(4)(A) of the Code. The
Small Business Job Protection Act of 1996 repealed the application of Section
593(d) of the Code to any taxable year beginning after December 31, 1995.
Entities affected by the foregoing provisions of the Code that are considering
the purchase of certificates should consult their own tax advisors regarding
these provisions.     
   
    Original Issue Discount. Regular Certificates may be issued with "original
issue discount." Rules governing original issue discount are set forth in
Sections 1271-1273 and 1275 of the Code and the Treasury regulations issued
thereunder in January 1994, as amended in June 1996 (the "OID Regulations").
The discussion herein is based in part on the OID Regulations, which generally
apply to debt instruments issued on or after April 4, 1994, but which generally
may be relied upon for debt instruments issued after December 21, 1992.
Moreover, although the rules relating to original issue discount contained in
the Code were modified by the Tax Reform Act of 1986 specifically to address
the tax treatment of securities, such as the Regular Certificates, on which
principal is required to be prepaid based on prepayments of the underlying
assets, regulations under that legislation have not yet been finalized.
Certificateholders also should be aware that the OID Regulations do not address
certain issues relevant to prepayable securities such as the Regular
Certificates.     
       
                                       50
<PAGE>
 
   
    In general, in the hands of the original holder of a Regular Certificate,
original issue discount, if any, is the difference between the "stated
redemption price at maturity" of the Regular Certificate and its "issue price."
The original issue discount with respect to a Regular Certificate will be
considered to be zero if it is less than .25% of the Regular Certificate's
stated redemption price at maturity multiplied by the number of complete years
from the date of issue of the Regular Certificate to its maturity date. The OID
Regulations, however, provide a special de minimis rule to apply to obligations
such as the Regular Certificates that have more than one principal payment or
that have interest payments that are not qualified stated interest as defined
in the OID Regulations, payable before maturity ("installment obligations").
Under the special rule, original issue discount on an installment obligation is
generally considered to be zero if it is less than .25% of the principal amount
of the obligation multiplied by the weighted average maturity of the obligation
as defined in the OID Regulations. Because of the possibility of prepayments,
it is not clear whether or how the de minimis rules will apply to the Regular
Certificates. It is possible that the anticipated rate of prepayments assumed
in pricing the debt instrument (the "Prepayment Assumption") will be required
to be used in determining the weighted average maturity of the Regular
Certificates. In the absence of authority to the contrary, Green Tree expects
to apply the de minimis rule applicable to installment obligations by using the
Prepayment Assumption. The OID Regulations provide a further special de minimis
rule applicable to any Regular Certificates that are "self-amortizing
installment obligations," i.e., Regular Certificates that provide for equal
payments composed of principal and qualified stated interest payable
unconditionally at least annually during its entire term, with no significant
additional payment required at maturity. Under this special rule, original
issue discount on a self-amortizing installment obligation is generally
considered to be zero if it is less than .167% of the principal amount of the
obligation multiplied by the number of complete years from the date of issue of
such a Regular Certificate to its maturity date.     
   
    Generally, the original holder of a Regular Certificate that includes a de
minimis amount of original issue discount includes that original issue discount
in income as principal payments are made. The amount includable in income with
respect to each principal payment equals a pro rata portion of the entire
amount of de minimis original issue discount with respect to that Regular
Certificate. Any de minimis amount of original issue discount includable in
income by a holder of a Regular Certificate is generally treated as a capital
gain if the Regular Certificate is a capital asset in the hands of the holder
of the certificate. Pursuant to the OID Regulations, a holder of a Regular
Certificate that uses the accrual method of tax accounting or that acquired the
Regular Certificate on or after April 4, 1994, may, however, elect to include
in gross income all interest that accrues on a Regular Certificate, including
any de minimis original issue discount and market discount, by using the
constant yield method described below with respect to original issue discount.
       
    The stated redemption price at maturity of a Regular Certificate generally
will be equal to the sum of all payments, whether denominated as principal or
interest, to be made with respect thereto other than "qualified stated
interest." Pursuant to the OID Regulations, qualified stated interest is stated
interest that is unconditionally payable at least annually at a single fixed
rate of interest (or, under certain circumstances, a variable rate tied to an
    
                                       51
<PAGE>
 
   
objective index) during the entire term of the Regular Certificate, including
short periods. Under the OID Regulations, interest is considered
unconditionally payable only if reasonable legal remedies exist to compel
timely payment or the debt instrument otherwise provides terms and conditions
that make the likelihood of late payment or nonpayment a remote contingency. It
is possible that interest payable on Regular Certificates may be considered not
to be unconditionally payable under the OID Regulations. Until further guidance
is issued, however, the REMIC will treat the interest on Regular Certificates
as unconditionally payable under the OID Regulations. In addition, under the
OID Regulations, certain variable interest rates payable on Regular
Certificates, including rates based upon the weighted average interest rate of
a pool of contracts, might not be treated as qualified stated interest. In this
case, the OID Regulations would treat interest under these rates as contingent
interest which generally must be included in income by the Regular
Certificateholder when the interest becomes fixed, as opposed to when it
accrues. Until further guidance is issued concerning the treatment of the
interest payable on Regular Certificates, the REMIC will treat the interest as
being payable at a variable rate tied to a single objective index of market
rates. Prospective investors should consult their tax advisors regarding the
treatment of the interest under the OID Regulations. In the absence of
authority to the contrary and if otherwise appropriate, Green Tree expects to
determine the stated redemption price at maturity of a Regular Certificate by
assuming that the anticipated rate of prepayment for all contracts will occur
in such a manner that the initial remittance rate for a certificate will not
change. Accordingly, interest at the initial remittance rate will constitute
qualified stated interest payments for purposes of applying the original issue
discount provisions of the Code. In general, the issue price of a Regular
Certificate is the first price at which a substantial amount of the Regular
Certificates of the class are sold for money to the public, excluding bond
houses, brokers or similar persons or organizations acting in the capacity of
underwriters, placement agents or wholesalers. If a portion of the initial
offering price of a Regular Certificate is allocable to interest that has
accrued prior to its date of issue, the issue price of such a Regular
Certificate includes that pre-issuance accrued interest.     
   
    If the Regular Certificates are determined to be issued with original issue
discount, a holder of a Regular Certificate must generally include the original
issue discount in ordinary gross income for federal income tax purposes as it
accrues in advance of the receipt of any cash attributable to such income. The
amount of original issue discount, if any, required to be included in a Regular
Certificateholder's ordinary gross income for federal income tax purposes in
any taxable year will be computed in accordance with Section 1272(a) of the
Code and the OID Regulations. Under this section and the OID Regulations,
original issue discount accrues on a daily basis under a constant yield method
that takes into account the compounding of interest. The amount of original
issue discount to be included in income by a holder of a debt instrument, such
as a regular certificate, under which principal payments may be subject to
acceleration because of prepayments of other debt obligations securing such
instruments, is computed by taking into account the Prepayment Assumption.     
   
    The amount of original issue discount includable in income by a holder of a
Regular Certificate is the sum of the "daily portions" of the original issue
discount for each day during the taxable year on which the holder held the
Regular Certificate. The daily portions     
 
                                       52
<PAGE>
 
   
of original issue discount are determined by allocating to each day in any
"accrual period" a pro rata portion of the excess, if any, of the sum of (1)
the present value of all remaining payments to be made on the Regular
Certificate as of the close of the "accrual period" and (2) the payments during
the "accrual period" of amounts included in the stated redemption price of the
Regular Certificate over the "adjusted issue price" of the Regular Certificate
at the beginning of the "accrual period." Generally, the "accrual period" for
the Regular Certificates corresponds to the intervals at which amounts are paid
or compounded with respect to such Regular Certificate, beginning with their
date of issuance and ending with the maturity date. The "adjusted issue price"
of a Regular Certificate at the beginning of any accrual period is the sum of
the issue price and accrued original issue discount for each prior accrual
period reduced by the amount of payments other than payments of qualified
stated interest made during each prior accrual period. The Code requires the
present value of the remaining payments to be determined on the bases of:     
     
  .  the original yield to maturity, determined on the basis of compounding
     at the close of each accrual period and properly adjusted for the
     length of the accrual period;     
     
  .  events, including actual prepayments, which have occurred before the
     close of the accrual period; and     
     
  .  the assumption that the remaining payments will be made in accordance
     with the original Prepayment Assumption.     
   
The effect of this method is to increase the portions of original issue
discount that a Regular Certificateholder must include in income to take into
account prepayments with respect to the contracts held by the Trust Fund that
occur at a rate that exceeds the Prepayment Assumption and to decrease, but not
below zero for any period, the portions of original issue discount that a
Regular Certificateholder must include in income to take into account
prepayments on to the contracts that occur at a rate that is slower than the
Prepayment Assumption. Although original issue discount will be reported to
Regular Certificateholders based on the Prepayment Assumption, no
representation is made to Regular Certificateholders that the Contracts will be
prepaid at that rate or at any other rate.     
   
    A subsequent purchaser of a Regular Certificate will also be required to
include in the purchaser's ordinary gross income for federal income tax
purposes the original issue discount, if any, accruing with respect to the
Regular Certificate, unless the price paid equals or exceeds the Regular
Certificate's outstanding principal amount. If the price paid exceeds the sum
of the Regular Certificate's issue price plus the aggregate amount of original
issue discount accrued on the Regular Certificate, but does not equal or exceed
the outstanding principal amount of the Regular Certificate, the amount of
original issue discount to be accrued will be reduced in accordance with a
formula listed in Section 1272(a)(7)(B) of the Code.     
   
    Green Tree believes that the holder of a Regular Certificate determined to
be issued with non-de minimis original issue discount will be required to
include the original issue discount in ordinary gross income for federal income
tax purposes computed in the manner described above. However, the OID
Regulations either do not address or are subject to     
 
                                       53
<PAGE>
 
   
varying interpretations regarding several issues concerning the computation of
original issue discount for obligations such as the Regular Certificates.     
   
    Variable Rate Regular Certificates. Regular Certificates may bear interest
at a variable rate. Under the OID Regulations, if a variable rate Regular
Certificate provides for qualified stated interest payments computed on the
basis of certain qualified floating rates or objective rates, then any original
issue discount on a Regular Certificate is computed and accrued under the same
methodology that applies to Regular Certificates paying qualified stated
interest at a fixed rate. See the discussion above under "REMIC Series--
Original Issue Discount." Accordingly, if the issue price of such a Regular
Certificate is equal to its stated redemption price at maturity, the Regular
Certificate will not have any original issue discount.     
   
    For purposes of applying the original issue discount provisions of the
Code, all or a portion of the interest payable on a variable rate Regular
Certificate may not be treated as qualified stated interest in certain
circumstances, including the following:     
     
  .  if the variable rate of interest is subject to one or more minimum or
     maximum rate floors or ceilings which are not fixed throughout the term
     of the Regular Certificate and which are reasonably expected as of the
     issue date to cause the rate in certain accrual periods to be
     significantly higher or lower than the overall expected return on the
     Regular Certificate determined without the floor or ceiling;     
     
  .  if it is reasonably expected that the average value of the variable
     rate during the first half of the term of the Regular Certificate will
     be either significantly less than or significantly greater than the
     average value of the rate during the final half of the term of the
     Regular Certificate; or     
     
  .  if interest is not payable in all circumstances.     
            
In these situations, as well as others, it is unclear under the OID Regulations
whether these interest payments constitute qualified stated interest payments,
or must be treated either as part of a Regular Certificate's stated redemption
price at maturity resulting in original issue discount, or represent contingent
payments which are recognized as ordinary gross income for federal income tax
purposes only as the interest payments become fixed in each accrual period.
       
    If a variable rate Regular Certificate is deemed to have been issued with
original issue discount, as described above, the amount of original issue
discount accrues on a daily basis under a constant yield method that takes into
account the compounding of interest; provided, however, that the interest
associated with the Regular Certificate generally is assumed to remain constant
throughout the term of the Regular Certificate at a rate that, in the case of a
qualified floating rate, equals the value of such qualified floating rate as of
the issue date of the Regular Certificate, or, in the case of an objective
rate, at a fixed rate that reflects the yield that is reasonably expected for
the Regular Certificate. A holder of such a Regular Certificate would then
recognize original issue discount during each accrual period which is     
 
                                       54
<PAGE>
 
calculated based upon such Regular Certificate's assumed yield to maturity,
adjusted to reflect the difference between the assumed and actual interest
rate.
   
    The OID Regulations either do not address or are subject to varying
interpretations on several issues concerning the computation of original issue
discount of the Regular Certificates, including variable rate Regular
Certificates. Additional information regarding the manner of reporting original
issue discount to the IRS and to holders of variable rate Regular Certificates
will be provided in the prospectus supplement relating to the issuance of the
Regular Certificates.     
   
    Market Discount. Regular Certificates, whether or not issued with original
issue discount, will be subject to the market discount rules of the Code. A
purchaser of a Regular Certificate who purchases the Regular Certificate at a
market discount (i.e., a discount from its original issue price plus any
accrued original issue discount, if any, as described above) will be required
to recognize accrued market discount as ordinary income as payments of
principal are received on such Regular Certificate or upon the sale or exchange
of the Regular Certificate. In general, the holder of a Regular Certificate may
elect to treat market discount as accruing either (1) under a constant yield
method that is similar to the method for the accrual of original issue discount
or (2) in proportion to accruals of original issue discount (or, if there is no
original issue discount, in proportion to accruals of stated interest), in each
case computed taking into account the Prepayment Assumption.     
   
    The Code provides that the market discount on a Regular Certificate will be
considered to be zero if the amount allocable to the Regular Certificate is
less than 0.25% of the Regular Certificate's stated redemption price at
maturity multiplied by the number of complete years remaining to its maturity
after the holder acquired the obligation. If market discount is treated as de
minimis under this rule, the actual discount would be allocated among a portion
of each scheduled distribution representing the stated redemption price of the
Regular Certificate and that portion of the discount allocable to such
distribution would be reported as income when the distribution occurs or is
due.     
   
    The Code further provides that any principal payment on a Regular
Certificate acquired with market discount or any gain on disposition of a
Regular Certificate shall be treated as ordinary income to the extent it does
not exceed the accrued market discount at the time of such payment. The amount
of accrued market discount for purposes of determining the amount of ordinary
income to be recognized with respect to subsequent payments on such a Regular
Certificate is to be reduced by the amount previously treated as ordinary
income.     
   
    The Code grants authority to the Treasury Department to issue regulations
providing for the computation of accrued market discount on debt instruments
such as the Regular Certificates. Until those regulations are issued, rules
described in the legislative history for these provisions of the Code will
apply. Under those rules, as described above, the holder of a Regular
Certificate with market discount may elect to accrue market discount either on
the basis of a constant interest rate or according to certain other methods.
Certificateholders who     
 
                                       55
<PAGE>
 
acquire a Regular Certificate at a market discount should consult their tax
advisors concerning various methods which are available for accruing that
market discount.
   
    In general, limitations imposed by the Code that are intended to match
deductions with the taxation of income may require a holder of a Regular
Certificate having market discount to defer a portion of the interest
deductions attributable to any indebtedness incurred or continued to purchase
or carry such Regular Certificate. Alternatively, a holder of a Regular
Certificate may elect to include market discount in gross income as it accrues
and, if he or she makes such an election, is exempt from this rule. Any
election made on a Regular Certificate issued with market discount will apply
to all Regular Certificates acquired by the holder on or after the first day of
the first taxable year to which such election applies and may be revoked only
with the consent of the IRS. The adjusted basis of a Regular Certificate
subject to such election will be increased to reflect market discount included
in gross income, thereby reducing any gain or increasing any loss on a sale or
taxable disposition.     
   
    Amortizable Premium. A holder of a Regular Certificate who holds the
Regular Certificate as a capital asset and who purchased the Regular
Certificate at a cost greater than its outstanding principal amount will be
considered to have purchased the Regular Certificate at a premium. In general,
the Regular Certificateholder may elect to deduct the amortizable bond premium
as it accrues under a constant yield method. A Regular Certificateholder's tax
basis in the Regular Certificate will be reduced by the amount of the
amortizable bond premium deducted. In addition, it appears that the same
methods which apply to the accrual of market discount on installment
obligations are intended to apply in computing the amortizable bond premium
deduction with respect to a Regular Certificate. It is not clear, however, (1)
whether the alternatives to the constant-yield method which may be available
for the accrual of market discount are available for amortizing premium on
Regular Certificates and (2) whether the Prepayment Assumption should be taken
into account in determining the term of a Regular Certificate for this purpose.
Certificateholders who pay a premium for a Regular Certificate should consult
their tax advisors concerning such an election and rules for determining the
method for amortizing bond premium.     
   
    Gain or Loss on Disposition. If a Regular Certificate is sold, the seller
will recognize gain or loss equal to the difference between the amount realized
from the sale and the seller's adjusted basis in such Regular Certificate. The
adjusted basis generally will equal the cost of such Regular Certificate to the
seller, increased by any original issue discount included in the seller's
ordinary gross income with respect to such Regular Certificate and reduced, but
not below zero, by any payments on the Regular Certificate previously received
or accrued by the seller, other than qualified stated interest payments, and
any amortizable premium. Similarly, a Regular Certificateholder who receives a
principal payment with respect to a Regular Certificate will recognize gain or
loss equal to the difference between the amount of the payment and the holder's
allocable portion of his or her adjusted basis in the Regular Certificate.
Except as discussed below or with respect to market discount, any gain or loss
recognized upon a sale, exchange, retirement, or other disposition of a Regular
Certificate will be capital gain if the Regular Certificate is held as a
capital asset.     
 
 
                                       56
<PAGE>
 
    Any capital gain recognized upon a sale, exchange or other disposition of a
Regular Certificate will be long-term capital gain if the seller's holding
period is more than one year and will be short-term capital gain if the
seller's holding period is one year or less. The deductibility of capital
losses is subject to certain limitations.
   
    Gain from the disposition of a Regular Certificate that might otherwise be
capital gain, including any gain attributable to de minimis original issue
discount, will be treated as ordinary income to the extent of the excess, if
any, of (1) the amount that would have been includable in the holder's income
if the yield on the Regular Certificate had equaled 110% of the applicable
federal rate determined as of the beginning of the holder's holding period,
over (2) the amount of ordinary income actually recognized by the holder with
respect to the Regular Certificate.     
   
    If Green Tree is determined to have intended on the date of issue of the
Regular Certificates to call all or any portion of the Regular Certificates
before their stated maturity within the meaning of Section 1271(a)(2)(A) of the
Code, any gain realized upon a sale, exchange, retirement, or other disposition
of a Regular Certificate would be considered ordinary income to the extent it
does not exceed the unrecognized portion of the original issue discount, if
any, with respect to the Regular Certificate. The OID Regulations provide that
the intention to call rule will not be applied to mortgage-backed securities
such as the Regular Certificates. In addition, under the OID Regulations, a
mandatory sinking fund or call option is not evidence of an intention to call.
       
    Taxation of Residual Interests. Generally, the "daily portions" of the
taxable income or net loss of a REMIC will be includable as ordinary income or
loss in determining the taxable income of holders of Residual Certificates
("Residual Holders"), and will not be taxed separately to the REMIC. The daily
portions are determined by allocating the REMIC's taxable income or net loss
for each calendar quarter ratably to each day in the quarter and by allocating
such daily portion among the Residual Holders in proportion to their respective
holdings of Residual Certificates in the REMIC on that day.     
   
    REMIC taxable income is generally determined in the same manner as the
taxable income of an individual using the accrual method of accounting except
that:     
     
  .  the limitation on deductibility of investment interest expense and
     expenses for the production of income do not apply,     
     
  .  all bad loans will be deductible as business bad debts, and     
     
  .  the limitation on the deductibility of interest and expenses related to
     tax-exempt income will apply.     
   
REMIC taxable income generally means a REMIC's gross income, including
interest, original issue discount income, and market discount income, if any,
on the contracts, plus income on reinvestment of cash flows and reserve assets,
minus deductions, including interest and original issue discount expense on the
Regular Certificates, servicing fees on the     
 
                                       57
<PAGE>
 
   
contracts, other administrative expenses of a REMIC, and amortization of
premium, if any, with respect to the contracts.     
   
    The taxable income recognized by a Residual Holder in any taxable year will
be affected by, among other factors, the relationship between the timing of
interest, original issue discount or market discount income, or amortization of
premium with respect to the contracts, on the one hand, and the timing of
deductions for interest, including original issue discount, on the Regular
Certificates, on the other hand. In the event that an interest in the contracts
is acquired by a REMIC at a discount, and one or more of such contracts is
prepaid, the Residual Holder may recognize taxable income without being
entitled to receive a corresponding cash distribution because:     
     
  .  the prepayment may be used in whole or in part to make distributions on
     Regular Certificates, and     
     
  .  the discount on the contracts which is includable in a REMIC's income
     may exceed its deduction with respect to the distributions on those
     Regular Certificates.     
   
When there is more than one class of Regular Certificates that receive payments
sequentially (i.e., a fast-pay, slow-pay structure), this mismatching of income
and deductions is particularly likely to occur in the early years following
issuance of the Regular Certificates, when distributions are being made on
earlier classes of Regular Certificates to the extent that the classes are not
issued with substantial discount. If taxable income attributable to the
mismatching is realized, in general, losses would be allowed in later years as
distributions on the later classes of Regular Certificates are made. Taxable
income may also be greater in earlier years than in later years because
interest expense deductions, expressed as a percentage of the outstanding
principal amount of Regular Certificates, may increase over time as
distributions are made on the lower yielding classes of Regular Certificates,
whereas interest income on any given contract will remain constant over time as
a percentage of the outstanding principal amount of that loan, assuming it
bears interest at a fixed rate. Consequently, Residual Holders must have
sufficient other sources of cash to pay any federal, state, or local income
taxes due as a result of this mismatching, or the holders must have unrelated
deductions against which to offset this income, subject to the discussion of
"excess inclusions" below under "REMIC Series--Limitations on Offset or
Exemption of REMIC Income." The mismatching of income and deductions described
in this paragraph, if present with respect to a series of certificates, may
have a significant adverse effect upon the Residual Holder's after-tax rate of
return.     
   
    The amount of any net loss of a REMIC that may be taken into account by the
Residual Holder is limited to the adjusted basis of the Residual Certificate as
of the close of the quarter, or time of disposition of the Residual Certificate
if earlier, determined without taking into account the net loss for the
quarter. The initial adjusted basis of a purchaser of a Residual Certificate is
the amount paid for such Residual Certificate. This adjusted basis will be
increased by the amount of taxable income of the REMIC reportable by the
Residual Holder and decreased by the amount of loss of the REMIC reportable by
the Residual Holder. A cash distribution from the REMIC also will reduce such
adjusted basis, but not     
 
                                       58
<PAGE>
 
   
below zero. Any loss that is disallowed on account of this limitation may be
carried over indefinitely by the Residual Holder for whom the loss was
disallowed and may be used by the Residual Holder only to offset any income
generated by the same REMIC.     
   
    If a Residual Certificate has a negative value, it is not clear whether its
issue price would be considered to be zero or such negative amount for purposes
of determining the REMIC's basis in its assets. The REMIC Regulations imply
that residual interests cannot have a negative basis or a negative issue price.
However, the preamble to the REMIC Regulations indicates that, while existing
tax rules do not accommodate these concepts, the IRS is considering the tax
treatment of these types of residual interests, including the proper tax
treatment of a payment made by the transferor of the residual interest to
induce the transferee to acquire that interest. Absent regulations or
administrative guidance to the contrary, Green Tree does not intend to treat a
class of Residual Certificates as having a value of less than zero for purposes
of determining the basis of the related REMIC in its assets.     
   
    Further, to the extent that the initial adjusted basis of a Residual
Holder, other than an original holder in the Residual Certificate is greater
than the corresponding portion of the REMIC's basis in the contracts, the
Residual Holder will not recover a portion of such basis until termination of
the REMIC unless Treasury Regulations yet to be issued provide for periodic
adjustments to the REMIC income otherwise reportable by such holder.     
 
    Treatment of Certain Items of REMIC Income and Expense. Generally, a
REMIC's deductions for original issue discount will be determined in the same
manner as original issue discount income on Regular Certificates as described
above under "REMIC Series--Original Issue Discount" and "--Variable Rate
Regular Certificates," without regard to the de minimis rule described therein.
   
    The REMIC will have market discount income in respect of the contracts if,
in general, the basis of the REMIC in the contracts is exceeded by their unpaid
principal balances. The REMIC's basis in the contracts is generally the fair
market value of the contracts immediately after their transfer to the REMIC,
which may equal a proportionate part of the aggregate fair market value of the
REMIC Certificates. In respect of the contracts that have market discount to
which Code Section 1276 applies, the accrued portion of the market discount
would be recognized currently as an item of ordinary income. Market discount
income generally should accrue in the manner described above under "REMIC
Series--Market Discount."     
   
    Generally, if the basis of a REMIC in the contracts exceeds the unpaid
principal balances thereof, the REMIC will be considered to have acquired such
contracts at a premium equal to the amount of such excess. As stated above, the
REMIC's basis in the contracts is the fair market value of the contracts
immediately after the transfer thereof to the REMIC. Generally, a person that
holds a contract as a capital asset may elect to amortize premium on the
contracts under a constant interest method. See the discussion under "REMIC
Series--Amortizable Premium."     
 
                                       59
<PAGE>
 
   
    Limitations on Offset or Exemption of REMIC Income. If the aggregate value
of the Residual Certificates relative to the aggregate value of the Regular
Certificates and Residual Certificates is considered to be "significant," as
described below, then a portion but not all of the REMIC taxable income
includable in determining the federal income tax liability of a Residual Holder
will be subject to special treatment. That portion, referred to as the "excess
inclusion," is equal to the excess of REMIC taxable income for the calendar
quarter allocable to a Residual Certificate over the daily accruals for such
quarterly period of (1) 120% of the long-term applicable federal rate that
would have applied to the Residual Certificate if it were a debt instrument on
the startup day under Section 1274(d) of the Code, multiplied by (2) the
adjusted issue price of such Residual Certificate at the beginning of such
quarterly period. For this purpose, the adjusted issue price of a Residual
Certificate at the beginning of a quarter is the issue price of the Residual
Certificate, plus the amount of such daily accruals of REMIC income described
in this paragraph for all prior quarters, decreased by any distributions made
with respect to such Residual Certificate before the beginning of the quarterly
period. The value of the Residual Certificates would be considered significant
in cases where the aggregate issue price of the Residual Certificates is at
least 2% of the aggregate issue price of the Regular Certificates and Residual
Certificates, and the anticipated weighted average life of the Residual
Certificates is at least 20% of the anticipated weighted average life of the
REMIC.     
   
    The portion of a Residual Holder's REMIC taxable income consisting of the
excess inclusions generally may not be offset by other deductions on the
Residual Holder's tax return, including net operating loss carry forwards.
Further, if the Residual Holder is an organization subject to the tax on
unrelated business income imposed by Section 511 of the Code, the Residual
Holder's excess inclusions will be treated as unrelated business taxable income
of such Residual Holder for purposes of Section 511. Finally, if a real estate
investment trust or regulated investment company owns a Residual Certificate, a
portion (allocated under Treasury Regulations yet to be issued) of dividends
paid by the real estate investment trust or regulated investment company could
not be offset by net operating losses of its shareholders, would constitute
unrelated business taxable income for tax-exempt shareholders, and would be
ineligible for reduction of withholding to certain persons who are not U.S.
persons.     
 
    The Small Business Job Protection Act of 1996 has eliminated the special
rule permitting Section 593 institutions ("thrift institutions") to use net
operating losses and other allowable deductions to offset their excess
inclusion income from REMIC residual certificates that have "significant value"
within the meaning of the REMIC Regulations, effective for taxable years
beginning after December 31, 1995, except with respect to residual certificates
continuously held by a thrift institution since November 1, 1995.
 
    In addition, the Small Business Job Protection Act of 1996 provides three
rules for determining the effect of excess inclusions on the alternative
minimum taxable income of a residual holder. First, alternative minimum taxable
income for such residual holder is determined without regard to the special
rule that taxable income cannot be less than excess inclusions. Second, a
residual holder's alternative minimum taxable income for a tax year
 
                                       60
<PAGE>
 
cannot be less than the excess inclusions for the year. Third, the amount of
any alternative minimum tax net operating loss deductions must be computed
without regard to any excess inclusions. These rules are effective for tax
years beginning after December 31, 1986, unless a residual holder elects to
have such rules apply only to tax years beginning after August 20, 1996.
   
    Restrictions on Transfer of Residual Certificates. As described above under
"REMIC Series--Qualification as a REMIC," an interest in a Residual Certificate
may not be transferred to a Disqualified Organization. If any legal or
beneficial interest in a Residual Certificate is, nonetheless, transferred to a
Disqualified Organization, a tax would be imposed in an amount equal to the
product of (1) the present value of the total anticipated excess inclusions
with respect to such Residual Certificate for periods after the transfer, and
(2) the highest marginal federal income tax rate applicable to corporations.
The anticipated excess inclusions are based on actual prepayment experience to
the date of the transfer and projected payments based on the Prepayment
Assumption. The present value rate equals the applicable federal rate under
Section 1274(d) of the Code as of the date of the transfer for a term ending on
the close of the last quarter in which excess inclusions are expected to
accrue. Such rate is applied to the anticipated excess inclusions from the end
of the remaining calendar quarters in which they arise to the date of the
transfer. Such a tax generally would be imposed on the transferor of the
Residual Certificate, except that where such transfer is through an agent
(including a broker, nominee, or other middleman) for a Disqualified
Organization, the tax would instead be imposed on such agent. However, a
transferor of a Residual Certificate would in no event be liable for such tax
with respect to a transfer if the transferee furnishes to the transferor an
affidavit, under penalties of perjury, that the transferee is not a
Disqualified Organization and, as of the time of the transfer, the transferor
does not have actual knowledge that such affidavit is false. The tax also may
be waived by the Treasury Department if the Disqualified Organization promptly
disposes of the residual interest and the transferor pays such amount of tax as
the Treasury Department may require (presumably, a corporate tax on the excess
inclusion for the period the residual interest is actually held by the
Disqualified Organization).     
   
    In addition, if a "Pass-Through Entity," as defined in the next paragraph,
below has excess inclusion income with respect to a Residual Certificate during
a taxable year and a Disqualified Organization is the record holder of an
equity interest in such entity, then a tax is imposed on such entity equal to
the product of (1) the amount of excess inclusions on the Residual Certificate
that are allocable to the interest in the Pass-Through Entity during the period
such interest is held by the Disqualified Organization, and (2) the highest
marginal federal income tax rate imposed on corporations. This tax would be
deductible from the ordinary gross income of the Pass-Through Entity for the
taxable year. The Pass-Through Entity would not be liable for the tax if it has
received an affidavit from the record holder that it is not a Disqualified
Organization and, during the period the person is the record holder of the
Residual Certificate, the Pass-Through Entity does not have actual knowledge
that the affidavit is false. For taxable years beginning after December 31
1997, notwithstanding the preceding sentences, in the case of a REMIC Residual
Certificate held by an "electing large partnership," all interests in the
partnership shall be treated as held by     
 
                                       61
<PAGE>
 
   
disqualified organizations, without regard to whether the recordholders of the
partnership furnish statements described in the preceding sentence, and the
amount that is subject to tax is excluded from the gross income of the
partnership allocated to the partners, in lieu of allocating to the partners a
deduction for the tax paid by the partnership.     
 
    For these purposes, a "Pass-Through Entity" means any regulated investment
company, real estate investment trust, common trust fund, partnership, trust or
estate and certain corporations operating on a cooperative basis. Except as may
be provided in Treasury Regulations, any person holding an interest in a Pass-
Through Entity as a nominee for another will, with respect to such interest, be
treated as a Pass-Through Entity.
   
    Noneconomic Residual Interests. The REMIC Regulations would disregard
certain transfers of Residual Certificates, in which case the transferor would
continue to be treated as the owner of the Residual Certificates and thus would
continue to be subject to tax on its allocable portion of the net income of the
REMIC. Under the REMIC Regulations, a transfer of a "noneconomic residual
interest" (as defined below) to a Residual Holder is disregarded for all
federal income tax purposes if a significant purpose of the transfer is to
enable the transferor to impede the assessment or collection of tax. A residual
interest in a REMIC, including a residual interest with a positive value at
issuance, is a "noneconomic residual interest" unless, at the time of transfer,
(1) the present value of the expected future distributions on the residual
interest at least equals the product of the present value of the anticipated
excess inclusions and the highest corporate income tax rate in effect for the
year in which the transfer occurs, and (2) the transferor reasonably expects
that the transferee will receive distributions from the REMIC at or after the
time at which taxes accrue on the anticipated excess inclusions in an amount
sufficient to satisfy the accrued taxes. The anticipated excess inclusions and
the present value rate are determined in the same manner as set forth above.
The REMIC Regulations explain that a significant purpose to impede the
assessment or collection of tax exists if the transferor, at the time of the
transfer, either knew or should have known that the transferee would be
unwilling or unable to pay taxes due on its share of the taxable income of the
REMIC. A safe harbor is provided if:     
     
  .  the transferor conducted, at the time of the transfer, a reasonable
     investigation of the financial condition of the transferee and found
     that the transferee historically had paid its debts as they came due
     and found no significant evidence to indicate that the transferee would
     not continue to pay its debts as they came due in the future, and     
     
  .  the transferee represents to the transferor that it understands that,
     as the holder of a non-economic residual interest, the transferee may
     incur tax liabilities in excess of any cash flows generated by the
     interest and that the transferee intends to pay taxes associated with
     holding the residual interest as they become due.     
   
The pooling and servicing agreement with respect to each series of REMIC
Certificates will require the transferee of a Residual Certificate to certify
to the statements in the second clause of the preceding sentence as part of the
affidavit described above under "Restrictions on Transfer of Residual
Certificates."     
 
                                       62
<PAGE>
 
   
    Sale or Exchange of a Residual Certificate. Upon the sale or exchange of a
Residual Certificate, the Residual Holder will recognize gain or loss equal to
the excess, if any, of the amount realized over the adjusted basis as described
above of the Residual Holder in the Residual Certificate at the time of the
sale or exchange. In addition to reporting the taxable income of the REMIC, a
Residual Holder will have taxable income to the extent that any cash
distribution to him from the REMIC exceeds such adjusted basis on that
distribution date. This income will be treated as gain from the sale or
exchange of the Residual Certificate. It is possible that the termination of
the REMIC may be treated as a sale or exchange of a Residual Holder's Residual
Certificate, in which case, if the Residual Holder has an adjusted basis in his
Residual Certificate remaining when his interest in the REMIC terminates, and
if he holds such Residual Certificate as a capital asset, then he will
recognize a capital loss at that time in the amount of such remaining adjusted
basis.     
   
    The Conference Committee Report to the Tax Reform Act of 1986 provides
that, except as provided in Treasury Regulations, the wash sale rules of Code
Section 1091 will apply to dispositions of Residual Certificates where the
seller of the Residual Certificate, during the period beginning six months
before the sale or disposition of the Residual Certificate and ending six
months after the sale or disposition, acquires (or enters into any other
transaction that results in the application of Code Section 1091) any residual
interest in any REMIC or any interest in a "taxable mortgage pool," such as a
non-REMIC owner trust, that is economically comparable to a Residual
Certificate.     
   
    Mark-to-Market of Residual Certificates. Prospective purchasers of a
Residual Certificate should be aware that the IRS recently released final
regulations (the "Mark-to-Market Regulations") which provide that a Residual
Certificate acquired after January 3, 1995 cannot be marked-to-market. The
Mark-to-Market Regulations changed the temporary regulations which allowed a
Residual Certificate to be marked-to-market provided that it was not a
"negative value" residual interest and did not have the same economic effect as
a "negative value" residual interest.     
   
    Certain Other Taxes on the REMIC. The REMIC provisions of the Code impose a
100% tax on any net income derived by a REMIC from certain prohibited
transactions. These transactions are:     
     
  .  any disposition of a qualified mortgage, other than pursuant to the
     substitution of a qualified replacement mortgage for a qualified
     mortgage (or the repurchase in lieu of substitution of a defective
     obligation), a disposition incident to the foreclosure, default, or
     imminent default of a mortgage, the bankruptcy or insolvency of the
     REMIC, or a qualified liquidation of the REMIC;     
     
  .  the receipt of income from assets other than qualified mortgages and
     permitted investments;     
     
  .  the receipt of compensation for services; and     
     
  .  the receipt of gain from the dispositions of cash flow investments.
         
                                       63
<PAGE>
 
   
The REMIC regulations provide that the modification of the terms of a contract
occasioned by default or a reasonably foreseeable default of the contract, the
assumption of the contract, the waiver of a due-on-sale clause or the
conversion of an interest rate by an obligor pursuant to the terms of a
convertible adjustable-rate contract will not be treated as a disposition of
the contract. In the event that a REMIC holds Convertible ARM Loans which are
convertible at the option of the obligor into fixed-rate, fully amortizing,
level payment contracts, a sale of the contracts by the REMIC pursuant to a
purchase agreement or other contract with Green Tree or other party, if and
when the obligor elects to so convert the terms of the contract, is not
expected to result in a prohibited transaction for the REMIC. The Code also
imposes a 100% tax on contributions to a REMIC made after the startup day,
unless such contributions are payments made to facilitate a cleanup call or a
qualified liquidation of the REMIC, payments in the nature of a guaranty,
contributions during the three-month period beginning on the startup day or
contributions to a qualified reserve fund of the REMIC by a holder of a
residual interest in the REMIC. The Code also imposes a tax on a REMIC at the
highest corporate rate on certain net income from foreclosure property that the
REMIC derives from the management, sale, or disposition of any real property,
or any personal property incident thereto, acquired by the REMIC in connection
with the default or imminent default of a loan. Generally, it is not
anticipated that a REMIC will generate a significant amount of such income.
       
    Liquidation of the REMIC. A REMIC may liquidate without the imposition of
entity-level tax only in a "qualified liquidation." A liquidation is considered
qualified if a REMIC adopts a plan of complete liquidation, which may be
accomplished by designating in the REMIC's final tax return a date on which
such adoption is deemed to occur and sells all of its assets (other than cash)
within the ninety-day period beginning on the date of the adoption of the plan
of liquidation, provided that it distributes to holders of Regular or Residual
Certificates, on or before the last day of the ninety-day liquidation period,
all the proceeds of the liquidation (including all cash), less amounts retained
to meet claims.     
   
    Taxation of Certain Foreign Investors. For purposes of this discussion, a
"Foreign Holder" is a certificateholder who holds a Regular Certificate and who
is not:     
     
  (1) a citizen or resident of the United States;     
     
  (2) a corporation, partnership, or other entity organized in or under the
      laws of the United States or a political subdivision (except, in the
      case of a partnership, to the extent provided in regulations);     
     
  (3) an estate the income of which is includible in gross income for United
      States tax purposes regardless of its source; or     
     
  (4) a trust if:     
       
    .  a court within the United States is able to exercise primary
       supervision over administration of the trust; and     
       
    .  one or more United States persons have authority to control all
       substantial decisions of the trust.     
 
                                       64
<PAGE>
 
   
To the extent prescribed in regulations by the Secretary of the Treasury, which
regulations have not yet been issued, a trust which was in existence on August
20, 1996 (other than a trust treated as owned by the grantor under Subpart E of
Part I of Subchapter J of Chapter 1 of the Code), and which was treated as a
United States person on August 19, 1996, may elect to continue to be treated as
a United States person notwithstanding the previous sentence. Unless the
interest on a Regular Certificate is effectively connected with the conduct by
the Foreign Holder of a trade or business within the United States, the Foreign
Holder is not subject to federal income or withholding tax on interest (or
original issue discount, if any) on a Regular Certificate (subject to possible
backup withholding of tax, discussed below), provided the Foreign Holder is not
a controlled foreign corporation related to Green Tree and does not own
actually or constructively 10% or more of the voting stock of Green Tree. To
qualify for this tax exemption, the Foreign Holder will be required to provide
periodically a statement signed under penalties of perjury certifying that the
Foreign Holder meets the requirements for treatment as a Foreign Holder and
providing the Foreign Holder's name and address. The statement, which may be
made on a Form W-8 or substantially similar substitute form, generally must be
provided in the year a payment occurs or in either of the two preceding years.
The statement must be provided, either directly or through clearing
organization or financial institution intermediaries, to the person that
otherwise would withhold tax. This exemption may not apply to a Foreign Holder
that owns both Regular Certificates and Residual Certificates. If the interest
on a Regular Certificate is effectively connected with the conduct by a Foreign
Holder of a trade or business within the United States, then the Foreign Holder
will be subject to tax at regular graduated rates. Foreign Holders should
consult their own tax advisors regarding the specific tax consequences of their
owning a Regular Certificate.     
   
    Any gain recognized by a Foreign Holder upon a sale, retirement or other
taxable disposition of a Regular Certificate generally will not be subject to
United States federal income tax unless either:     
     
  (1)  the Foreign Holder is a nonresident alien individual who holds the
       Regular Certificate as a capital asset and who is present in the
       United States for 183 days or more in the taxable year of the
       disposition and either the gain is attributable to an office or other
       fixed place of business maintained in the U.S. by the individual or
       the individual has a "tax home" in the United States; or     
     
  (2) the gain is effectively connected with the conduct by the Foreign
     Holder of a trade or business within the United States.     
   
    A Regular Certificate will not be includible in the estate of a Foreign
Holder who does not own actually or constructively 10% or more of the voting
stock of Green Tree.     
   
    Backup Withholding. Under certain circumstances, a REMIC certificateholder
may be subject to "backup withholding" at a 31% rate. Backup withholding may
apply to a REMIC certificateholder who is a United States person if the holder,
among other circumstances, fails to furnish his social security number or other
taxpayer identification number to the trustee. Backup withholding may apply,
under certain circumstances, to a REMIC     
 
                                       65
<PAGE>
 
   
certificateholder who is a foreign person if the REMIC certificateholder fails
to provide the trustee or the REMIC certificateholder's securities broker with
the statement necessary to establish the exemption from federal income and
withholding tax on interest on the REMIC certificate. Backup withholding,
however, does not apply to payments on a certificate made to certain exempt
recipients, such as corporations and tax-exempt organizations, and to certain
foreign persons. REMIC certificateholders should consult their tax advisors for
additional information concerning the potential application of backup
withholding to payments received by them with respect to a certificate.     
 
    On October 6, 1997, the Treasury Department issued new regulations which
make certain modifications to the withholding, backup withholding and
information reporting rules described above. The new regulations attempt to
unify certification requirements and modify reliance standards, and will
generally be effective for payments made after December 31, 1999, subject to
certain transition rules. Prospective investors are urged to consult their own
tax advisors regarding the new regulations.
   
    Reporting Requirements and Tax Administration. Green Tree will report
annually to the Service, holders of record of the Regular Certificates that are
not excepted from the reporting requirements and, to the extent required by the
Code, other interested parties, information with respect to the interest paid
or accrued on the Regular Certificates, original issue discount, if any,
accruing on the Regular Certificates and information necessary to compute the
accrual of any market discount or the amortization of any premium on the
Regular Certificates.     
   
    The Treasury Department has issued final regulations concerning certain
aspects of REMIC tax administration. Under those regulations, a Residual
Certificateholder must be designated as the REMICs "tax matters person." The
tax matters person, generally, has responsibility for overseeing and providing
notice to the other Residual Certificateholders of certain administrative and
judicial proceedings regarding the REMIC's tax affairs. Unless otherwise
indicated in the related prospectus supplement, Green Tree will be designated
as tax matters person for each REMIC, and in conjunction with the trustee will
act as the agent of the Residual Certificateholders in the preparation and
filing of the REMIC's federal and state income tax and other information
returns.     
 
Non-REMIC Series
   
    Tax Status of the Trust Fund. In the case of a trust fund evidenced by a
series or sub-series of certificates, or a segregated portion thereof, with
respect to which a REMIC election is not made ("Non-REMIC certificates"),
counsel will have advised Green Tree that, in their opinion, each Contract Pool
and the arrangement to be administered by Green Tree under which the trustee
will hold and Green Tree will be obligated to service the contracts and
pursuant to which Non-REMIC certificates will be issued to Non-REMIC
certificateholders will not be classified as an association taxable as a
corporation or a "taxable mortgage pool, within the meaning of Code Section
7701(i), but rather will be classified as a grantor trust under Subpart E, Part
I of Subchapter J of Chapter 1 of the Code.     
 
                                       66
<PAGE>
 
   
Each Non-REMIC certificateholder will be treated as the owner of a pro rata
undivided interest in the ordinary income and corpus portions of the trust
attributable to the contract pool in which its certificate evidences an
ownership interest and will be considered the equitable owner of a pro rata
undivided interest in each of the contracts included therein.     
       
    Tax Status of Non-REMIC Certificates. In general:     
     
  .  certificates held by a "domestic building and loan association" within
     the meaning of Section 7701(a)(19) of the Code may be considered to
     represent "qualifying real property loans" within the meaning of
     Section 7701(a)(19)(C)(v) of the Code; and     
     
  .  certificates held by a real estate investment trust may constitute
     "real estate assets" within the meaning of Section 856(c)(4)(A) of the
     Code and interest thereon may be considered "interest on obligations
     secured by mortgages on real property" within the meaning of Section
     856(c)(3)(B) of the Code.     
   
See the discussions of such Code provisions above under "REMIC Series Tax
Status of REMIC Certificates." Investors should review the related prospectus
supplement for a discussion of the treatment of Non-REMIC certificates and
contracts under these Code sections and should, in addition, consult with their
own tax advisors with respect to these matters.     
   
    Tax Treatment of Non-REMIC Certificates. Non-REMIC certificateholders will
be required to report on their federal income tax returns, and in a manner
consistent with their respective methods of accounting, their pro rata share of
the entire income arising from the contracts comprising such contract pool,
including interest, original issue discount, if any, prepayment fees,
assumption fees, and late payment charges received by Green Tree, and any gain
upon disposition of such contracts. For purposes of this discussion, the term
"disposition," when used with respect to the contracts, includes scheduled or
prepaid collections with respect to the contracts, as well as the sale or
exchange of a Non-REMIC certificate. Non-REMIC certificateholders will be
entitled under Section 162 or 212 of the Code to deduct their pro rata share of
related servicing fees, administrative and other non-interest expenses,
including assumption fees and late payment charges retained by Green Tree. An
individual, an estate, or a trust that holds a Non-REMIC certificate either
directly or through a pass-through entity will be allowed to deduct such
expenses under Section 212 of the Code only to the extent that, in the
aggregate and combined with certain other itemized deductions, they exceed 2%
of the adjusted gross income of the holder. In addition, Section 68 of the Code
provides that the amount of itemized deductions (including those provided for
in Section 212 of the Code) otherwise allowable for the taxable year for an
individual whose adjusted gross income exceeds a threshold amount specified in
the Code ($126,600 in 1999 in the case of a joint return) will be reduced by
the lesser of (1) 3% of the excess of adjusted gross income over the specified
threshold amount or (2) 80% of the amount of itemized deductions otherwise
allowable for such taxable year. To the extent that a Non-REMIC
certificateholder is not permitted to deduct servicing fees allocable to a Non-
REMIC certificate, the taxable income of the Non-REMIC certificateholder
attributable to that Non-REMIC certificate will exceed the net cash
distributions related to such income.     
 
                                       67

Non-REMIC certificateholders may deduct any loss on disposition of the
contracts to the extent permitted under the Code.     
   
    Under current IRS interpretations of applicable treasury regulations Green
Tree would be able to sell or otherwise dispose of any subordinated Non-REMIC
certificates. Accordingly, Green Tree expects to offer subordinated Non-REMIC
certificates for sale to investors. In general, such subordination should not
affect the federal income tax treatment of either the subordinated or senior
certificates. Holders of subordinated classes of certificates should be able to
recognize any losses allocated to such class when and if losses are realized.
       
    To the extent that any of the contracts comprising a contract pool were
originated on or after March 2, 1984 and under circumstances giving rise to
original issue discount, certificateholders will be required to report annually
an amount of additional interest income attributable to the discount in those
contracts prior to receipt of cash related to the discount. To the extent that
the Non-REMIC certificates represent an interest in any pool of debt
instruments the yield on which may be affected by reason of prepayments, for
taxable years beginning after August 5, 1997, a prepayment assumption must be
used with respect to the contracts comprising the contract pool in computing
the accrual of any original issue discount, market discount or amortizable
premiums. See the discussion above under "REMIC Series--Original Issue
Discount." Similarly, Code provisions concerning market discount and
amortizable premium will apply to the Contracts comprising a contract pool to
the extent that the loans were originated after July 18, 1984 and September 27,
1985, respectively. See the discussions above under "REMIC Series--Market
Discount" and "REMIC Series--Amortizable Premium." It is unclear whether a
prepayment assumption would be applicable in accruing or amortizing any such
original issue or market discount or premium with respect to Non-REMIC
certificates that do not represent an interest in any pool of debt instruments
the yield on which may be affected by reason of prepayments, or for taxable
years beginning prior to August 5, 1997.     
   
    Stripped Non-REMIC Certificates. Certain classes of Non-REMIC certificates
may be subject to the stripped bond rules of Section 1286 of the Code and for
purposes of this discussion will be referred to as "Stripped Certificates." In
general, a Stripped Certificate will be subject to the stripped bond rules
where there has been a separation of ownership of the right to receive some or
all of the principal payments on a contract from ownership of the right to
receive some or all of the related interest payments. Non-REMIC certificates
will constitute Stripped Certificates and will be subject to these rules under
various circumstances, including the following:     
     
  .  if any servicing compensation is deemed to exceed a reasonable amount;
            
  .  if Green Tree or any other party retains a Retained Yield with respect
     to the contracts comprising a contract pool;     
     
  .  if two or more classes of Non-REMIC certificates are issued
     representing the right to non-pro rata percentages of the interest or
     principal payments on the contracts; or     
 
 
                                       68
<PAGE>
 
     
  .  if Non-REMIC certificates are issued which represent the right to
     interest only payments or principal only payments.     
   
    Although not entirely clear, each Stripped Certificate should be considered
to be a single debt instrument issued on the day it is purchased for purposes
of calculating any original issue discount. Original issue discount with
respect to a Stripped Certificate, if any, must be included in ordinary gross
income for federal income tax purposes as it accrues in accordance with the
constant-yield method that takes into account the compounding of interest and
such accrual of income may be in advance of the receipt of any cash
attributable to such income. See "REMIC Series--Original Issue Discount" above.
For purposes of applying the original issue discount provisions of the Code,
the issue price of a Stripped Certificate will be the purchase price paid by
each holder thereof and the stated redemption price at maturity may include the
aggregate amount of all payments to be made with respect to the Stripped
Certificate whether or not denominated as interest. The amount of original
issue discount with respect to a Stripped Certificate may be treated as zero
under the original issue discount de minimis rules described above. A purchaser
of a Stripped Certificate will be required to account for any discount on the
certificate as market discount rather than original issue discount if either
(1) the amount of original issue discount with respect to the certificate was
treated as zero under the original issue discount de minimis rule when the
certificate was stripped or (2) no more than 100 basis points (including any
amount of servicing in excess of reasonable servicing) is stripped off of the
contracts. See "REMIC Series--Market Discount" above.     
   
    To the extent the Stripped Certificates represent an interest in any pool
of debt instrument the yield on which may by affected by reason of prepayments,
for taxable years beginning after August 5, 1997, a prepayment assumption must
be used in computing yield on the underlying assets of a trust fund with
respect to which a REMIC election is not made. It is unclear whether a
prepayment assumption would be applicable to the Stripped Certificates that do
not represent an interest in any such pool or for taxable years beginning prior
to August 5, 1997. The Code appears to require that such a prepayment
assumption be used in computing yield with respect to Stripped Certificates
that do not represent an interest in a pool of debt instruments the yield on
which may be affected by reason of prepayments or for taxable years beginning
prior to August 5, 1997. In the absence of authority to the contrary, Green
Tree intends to base information reports and returns to the IRS and the holders
of Stripped Certificates taking into account an appropriate prepayment
assumption. Holders of Stripped Certificates should refer to the related
prospectus supplement to determine whether and in what manner the original
issue discount rules will apply.     
 
    When an investor purchases more than one class of Stripped Certificates it
is currently unclear whether for federal income tax purposes such classes of
Stripped Certificates should be treated separately or aggregated for purposes
of applying the original issue discount rules described above.
 
 
                                       69
<PAGE>
 
          
    It is possible that the IRS may take a contrary position with respect to
some or all of the foregoing tax consequences. For example, a holder of a
Stripped Certificate may be treated as the owner of:     
     
  (1) as many stripped bonds or stripped coupons as there are scheduled
      payments of principal and/or interest on each contract; or     
     
  (2) a separate installment obligation for each contract representing the
      Stripped Certificate's pro rata share of principal and/or interest
      payments to be made with respect thereto.     
 
As a result of these possible alternative characterizations, investors should
consult their own tax advisors regarding the proper treatment of Stripped
Certificates for federal income tax purposes.
   
    Gain or Loss on Disposition. Upon sale or exchange of a Non-REMIC
certificate, a Non-REMIC certificateholder will recognize gain or loss equal to
the difference between the amount realized in the sale and its aggregate
adjusted basis in the contracts represented by the Non-REMIC certificate.
Generally, the aggregate adjusted basis will equal the Non-REMIC
certificateholder's cost for the Non-REMIC certificate increased by the amount
of any previously reported gain with respect to the Non-REMIC certificate and
decreased by the amount of any losses previously reported with respect to the
Non-REMIC certificate and the amount of any distributions received thereon.
Except as provided above with respect to the original issue discount and market
discount rules, any such gain or loss would be capital gain or loss if the Non-
REMIC certificate was held as a capital asset.     
   
    Recharacterization of Servicing Fees. The servicing compensation to be
received by Green Tree may be questioned by the IRS with respect to certain
certificates or contracts as exceeding a reasonable fee for the services being
performed in exchange therefor, and a portion of such servicing compensation
could be recharacterized as an ownership interest retained by Green Tree or
other party in a portion of the interest payments to be made pursuant to the
contracts. In this event, a certificate might be treated as a Stripped
Certificate subject to the stripped bond rules of Section 1286 of the Code and
the original issue discount provisions rather than to the market discount and
premium rules. See the discussion above under "Non-REMIC Series--Stripped Non-
REMIC Certificates."     
   
    Tax Treatment of Certain Foreign Investors. Generally, interest or original
issue discount paid to or accruing for the benefit of a Non-REMIC
certificateholder who is a Foreign Holder (as defined in "REMIC Series--
Taxation of Certain Foreign Investors") will be treated as "portfolio interest"
and therefore will be exempt from the 30% withholding tax. Such Non-REMIC
certificateholder will be entitled to receive interest payments and original
issue discount on the Non-REMIC certificates free of United States federal
income tax, but only to the extent the contracts were originated after July 18,
1984 and provided that such Non-REMIC certificateholder periodically provides
the Trustee (or other person who would otherwise be required to withhold tax)
with a statement certifying under penalty of perjury that such Non-REMIC
certificateholder is not a United States     
 
                                       70
<PAGE>
 
   
person and providing the name and address of such Non-REMIC certificateholder.
For additional information concerning interest or original issue discount paid
by Green Tree to a Foreign Holder and the treatment of a sale or exchange of a
Non-REMIC certificate by a Foreign Holder, which will generally have the same
tax consequences as the sale of a Regular certificate, see the discussion above
under "REMIC Series--Taxation of Certain Foreign Investors".     
   
    Tax Administration and Reporting. Green Tree will furnish to each Non-REMIC
certificateholder with each distribution a statement listing the amount of such
distribution allocable to principal and to interest. In addition, Green Tree
will furnish, within a reasonable time after the end of each calendar year, to
each Non-REMIC certificateholder who was a certificateholder at any time during
such year, information regarding the amount of servicing compensation received
by Green Tree and any sub-servicer and such other customary factual information
as Green Tree deems necessary or desirable to enable certificateholders to
prepare their tax returns. Reports will be made annually to the IRS and to
holders of record that are not excepted from the reporting requirements
regarding information as may be required with respect to interest and original
issue discount, if any, with respect to the Non-REMIC certificates.     
 
Other Tax Consequences
   
    No advice has been received as to local income, franchise, personal
property, or other taxation in any state or locality, or as to the tax effect
of ownership of certificates in any state or locality. Certificateholders are
advised to consult their own tax advisors with respect to any state or local
income, franchise, personal property, or other tax consequences arising out of
their ownership of certificates.     
 
                        LEGAL INVESTMENT CONSIDERATIONS
   
    Unless otherwise indicated in the applicable prospectus supplement, any
certificates offered under this prospectus that are rated in one of the two
highest rating categories by at least one nationally recognized statistical
rating organization will constitute "mortgage related securities" for purposes
of the Secondary Mortgage Market Enhancement Act of 1984 and, as such, will be
legal investments for persons, trusts, corporations, partnerships,
associations, business trusts and business entities, including depository
institutions, life insurance companies and pension funds, created under or
existing under the laws of the United States or of any state whose authorized
investments are subject to state regulation to the same extent as, under
applicable law, obligations issued by or guaranteed as to principal and
interest by the United States or any such entities. Under SMMEA, certain states
have created legislation specifically limiting the legal investment authority
of any such entities with respect to "mortgage related securities," in which
case the certificates will constitute legal investments for entities subject to
such legislation only to the extent provided therein. SMMEA provides, however,
that in no event will the enactment of any such legislation affect the validity
of any contractual commitment to purchase, hold or invest in certificates,     
 
                                       71
<PAGE>
 
   
or require the sale or other disposition of certificates, so long as such
contractual commitment was made or such certificates were acquired prior to the
enactment of the legislation.     
   
    SMMEA also amended the legal investment authority of federally-chartered
depository institutions as follows: federal savings and loan associations and
federal savings banks may invest in, sell or otherwise deal in certificates
without limitation as to the percentage of their assets represented thereby;
federal credit unions may invest in certificates; and national banks may
purchase certificates for their own account without regard to the limitations
generally applicable to investment securities set forth in 12 U.S.C. (S)24
(Seventh), subject in each case to such regulations as the applicable federal
regulatory authority may prescribe.     
   
    Some classes of certificates offered hereby may not be rated in one of the
two highest rating categories and thus would not constitute "mortgage related
securities" for purposes of SMMEA.     
   
    The Federal Financial Institutions Examination Council, The Federal Deposit
Insurance Corporation, the Office of Thrift Supervision, the Office of the
Comptroller of the Currency and the National Credit Union Administration have
proposed or adopted guidelines regarding investment in various types of
mortgage-backed securities. In addition, certain state regulators have taken
positions that may prohibit regulated institutions subject to their
jurisdiction from holding securities representing residual interests, including
securities previously purchased. There may be other restrictions on the ability
of certain investors, including depository institutions, either to purchase
certificates or to purchase certificates representing more than a specified
percentage of the investor's assets. Investors should consult their own legal
advisors in determining whether and to what extent the certificates constitute
legal investments for such investors.     
 
                                    RATINGS
   
    It is a condition precedent to the issuance of any class of certificates
sold under this prospectus that they be rated by at least one nationally
recognized statistical rating organization in one of its four highest rating
categories within which there may be sub-categories or gradations indicating
relative standing. A security rating is not a recommendation to buy, sell or
hold securities and may be subject to revision or withdrawal at any time by the
assigning rating agency. The security rating of any series of certificates
should be evaluated independently of similar security ratings assigned to other
kinds of securities.

<PAGE>
 
                                  UNDERWRITING
   
    Green Tree may sell certificates of each series to or through underwriters
by a negotiated firm commitment underwriting and public reoffering by the
underwriters, and also may sell and place certificates directly to other
purchasers or through agents. Green Tree intends that certificates will be
offered through various methods from time to time and that offerings may be
made concurrently through more than one of these methods or that an offering of
a particular series of certificates may be made through a combination of these
methods.     
   
    The distribution of the certificates may be effected from time to time in
one or more transactions at a fixed price or prices, which may be changed, or
at market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.     
   
    If so specified in the prospectus supplement relating to a series of
certificates, Green Tree or any affiliate thereof may purchase some or all of
one or more classes of certificates of such series from the underwriter or
underwriters at a price specified in such prospectus supplement. The purchaser
may thereafter from time to time offer and sell, under this prospectus, some or
all of the certificates so purchased directly, through one or more underwriters
to be designated at the time of the offering of the certificates or through
broker-dealers acting as agent and/or principal. The offering may be restricted
in the manner specified in the prospectus supplement. These transactions may be
effected at market prices prevailing at the time of sale, at negotiated prices
or at fixed prices.     
   
    In connection with the sale of the certificates, underwriters may receive
compensation from Green Tree or from purchasers of certificates for whom they
may act as agents in the form of discounts, concessions or commissions.
Underwriters may sell the certificates of a series to or through dealers and
such dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agents. Underwriters, dealers and agents that participate
in the distribution of the certificates of a series may be deemed to be
underwriters, and any discounts or commissions received by them from Green Tree
and any profit on the resale of the certificates by them may be deemed to be
underwriting discounts and commissions, under the Act. Any such underwriters or
agents will be identified, and any such compensation received from Green Tree
will be described, in the prospectus supplement.     
   
    Under agreements which may be entered into by Green Tree, underwriters and
agents who participate in the distribution of the certificates may be entitled
to indemnification by Green Tree against certain liabilities, including
liabilities under the Act.     
   
    If so indicated in the prospectus supplement, Green Tree will authorize
underwriters or other persons acting as Green Tree's agents to solicit offers
by certain institutions to purchase the certificates from Green Tree under
contracts providing for payment and delivery on a future date. Institutions
with which the contracts may be made include     
 
                                       73
<PAGE>
 
   
commercial and savings banks, insurance companies, pension funds, investment
companies, educational charitable institutions and others, but in all cases
such institutions must be approved by Green Tree. The obligation of any
purchaser under any contract will be subject to the condition that the
purchaser of the offered certificates shall not at the time of delivery be
prohibited under the laws of the jurisdiction to which the purchaser is subject
from purchasing such certificates. The underwriters and such other agents will
not have responsibility in respect of the validity or performance of such
contracts.     
   
    The underwriters may, from time to time, buy and sell certificates, but
there can be no assurance that an active secondary market will develop and
there is no assurance that any such market, if established, will continue.     
   
    Some persons participating in this offering may engage in transactions that
stabilize, maintain or in some way affect the price of the certificates. These
types of transactions may include stabilizing, the purchase of certificates to
cover syndicate short positions and the imposition of penalty bids. For a more
complete description of these activities, please read the section entitled
"Underwriting" in your prospectus supplement.     
   
    Certain of the underwriters and their associates may engage in transactions
with and perform services for Green Tree in the ordinary course of business.
    
                                 LEGAL MATTERS
   
    The legality and material federal income tax consequences of the
certificates will be passed upon for Green Tree by the counsel to Green Tree
identified in the applicable prospectus supplement.

Item 15. Indemnification of Directors and Officers
 
      Green Tree Financial Corporation is incorporated under the laws of
Delaware. Section 145 of the Delaware General Corporation Law provides that a
Delaware corporation may indemnify any persons, including officers and
directors, who are, or are threatened to be made, parties to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of
such corporation, by reason of the fact that such person was an officer,
director, employee or agent of such corporation, or is or was serving at the
request of such corporation as a director, employee or agent of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise). The
indemnity may include expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceeding, provided such person acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the corporation's best interests and, for criminal proceedings, had no
reasonable cause to believe that his conduct was illegal. A Delaware
corporation may indemnify officers and directors in an action by or in the
right of the corporation under the same conditions, except that no
indemnification is permitted without judicial approval if the officer or
director is adjudged to be liable to the corporation. Where and officer or
director is successful on the merits or otherwise in the defense of any action
referred to above, the corporation must indemnify him against the expenses
which such officer or director actually and reasonably incurred.
 
      The Certificate of Incorporation and Bylaws of Green Tree Financial
Corporation provide, in effect, that, subject to certain limited exceptions,
such corporation will indemnify its officers and directors to the extent
permitted by the Delaware General Corporation Law.
 
      The Company maintains a directors' and officers' insurance policy.
 
      Pursuant to the form of Underwriting Agreement, the Underwriters will
agree, subject to certain conditions, to indemnify the Company, its directors,
certain of their officers and any persons who control the Company, within the
meaning of the Securities Act of 1933, as amended (the "Securities Act"),
against certain liabilities.

Item 17. Undertakings
 
      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
      The undersigned registrant hereby undertakes that:
 
       (1) For purposes of determining any liability under the Securities
    Act of 1933, the information omitted from the form of prospectus filed
    as a part of this registration statement in reliance upon Rule 430A and
    contained in a form of prospectus filed by the registrant pursuant to
    Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed
    to be part of this registration statement as of the time it was declared
    effective.
 
                                      II-2
<PAGE>
 
       (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating
    to the securities offered therein, and the offering of such securities
    at that time shall be deemed to be the initial bona fide offering
    thereof.
 
      The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act
of 1934) that is incorporated by reference in the registration statement shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
      The undersigned registrant hereby undertakes:
 
       (1) To file, during any period in which offers or sales are being
    made, a post-effective amendment to this registration statement:
 
         (i) To include any prospectus required by section 10(a)(3) of
      the Securities Act of 1933;
 
         (ii) To reflect in the prospectus any facts or events arising
      after the effective date of the registration statement (or the most
      recent post-effective amendment thereof) which, individually or in
      the aggregate, represent a fundamental change to the information
      set forth in the registration statement. Notwithstanding the
      foregoing, any increase or decrease in volume of securities offered
      (if the total dollar value of securities offered would not exceed
      that which was registered) and any deviation from the low or high
      end of the estimated maximum offering range may be reflected in the
      form of prospectus filed with the Commission pursuant to Rule
      424(b) under the Securities Act of 1933 if, in the aggregate, the
      changes in volume and price represent no more than a 20% change in
      the maximum aggregate offering price set forth in the "Calculation
      of Registration Fee" table in the effective registration statement;
      and
 
         (iii) To include any material information with respect to the
      plan of distribution not previously disclosed in the registration
      statement or any material change to such information in the
      registration statement;
 
      Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply
      if the registration statement is on Form S-3 or Form S-8, and the
      information required to be included in a post-effective amendment
      by those paragraphs is contained in periodic reports filed by the
      registrant pursuant to section 13 or section 15(d) of the
      Securities Exchange Act of 1934 that are incorporated by reference
      in the registration statement.
 
       (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be
    deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall
    be deemed to be the initial bona fide offering thereof.
 
       (3) To remove from registration by means of a post-effective
    amendment any of the securities being registered which remains unsold at
    the termination of the offering.
 
      The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is
 
                                      II-3
<PAGE>
 
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
      The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.
