"PMBS"); and (d) all monies due thereunder net, if and as provided in the
related Prospectus Supplement, of certain amounts payable to the servicer of the
Loans, Agency Securities or Private Mortgage-Backed Securities. The Trust Fund
Assets will be acquired by the Depositor, either directly or indirectly, from
one or more institutions (each, a "Seller"), which may be affiliates of the
Depositor, and conveyed by the Depositor to the related Trust Fund. A Trust Fund
may include a number of different types and concentrations of Trust Fund Assets
to the extent described in the related Prospectus Supplement. A Trust Fund also

     Each Series of Securities will be issued in one or more classes. Each class
of Certificates of a Series will evidence beneficial ownership of a specified
percentage (which may be 0%) or portion of future interest payments and a
specified percentage (which may be 0%) or portion of future principal payments
on the related Trust Fund Assets. Each class of Notes of a Series will be
secured by the related Trust Fund Assets or, if so specified in the related
Prospectus Supplement, a portion thereof. A Series of Securities may include one
or more classes that are senior in right of payment to one or more other classes
of Securities of such Series. One or more classes of Securities of a Series may
be entitled to receive distributions of principal, interest or any combination
thereof prior to one or more other classes of Securities of such Series or after
the occurrence of specified events, in each case as specified in the related
Prospectus Supplement.
 
     Distributions to holders of Securities ("Securityholders") will be made
monthly, quarterly, semi-annually or at such other intervals and on the dates
specified in the related Prospectus Supplement. Distributions on the Securities
of a Series will be made from the related Trust Fund Assets or proceeds thereof
pledged for the benefit of the Securityholders as specified in the related
Prospectus Supplement.

provided with respect to the related Series of Securities including, without

Urban Development, the United States Department of Veterans' Affairs or any
private insurer or guarantor. Unless otherwise specified in the related
Prospectus Supplement, the only obligations of the Depositor with respect to a
Series of Securities will be to obtain certain representations and warranties
from each Seller or each originator (the "Originator") of the Trust Fund Assets
and to assign to the Trustee for the related Series of Securities the
Depositor's rights with respect to such representations and warranties. The
principal obligations of the Master Servicer named in the related Prospectus
Supplement with respect to the related Series of Securities will be limited to
obligations pursuant to certain representations and warranties and to its
contractual servicing obligations, including any obligation it may have to
advance delinquent payments on the related Trust Fund Assets.
 
     The yield on each class of Securities of a Series will be affected by,
among other things, the rate of payments of principal (including prepayments) on
the related Trust Fund Assets and the timing of receipt of such payments as
described under "Risk Factors -- Prepayment and Yield Considerations and
Reinvestment Risk" and "Yield and Prepayment Considerations" herein and in the
related Prospectus Supplement. A Trust Fund may be subject to early termination
under the circumstances described under "The Agreements -- Termination; Optional
Termination" herein and in the related Prospectus Supplement.
 
     If specified in the related Prospectus Supplement, one or more elections
may be made to treat a Trust Fund or specified portions thereof as a "real

                             or Funds or other assets pledged for the benefit of
                             the Securities as described under "Credit

                             Distribution Date will be determined as specified
                             in the related Prospectus Supplement. The

                             will describe the method of allocating
                             distributions among Securities of different classes
                             as well as the method for allocating distributions
                             among Securities for any particular class.
 
                             Unless otherwise specified in the related
                             Prospectus Supplement, the aggregate original
                             principal balance of the Securities will not exceed
                             the aggregate distributions allocable to principal
                             that such Securities will be entitled to receive.
                             If specified in the related Prospectus Supplement,
                             the Securities will have an aggregate original
                             principal balance equal to the aggregate unpaid
                             principal balance of the Trust Fund Assets as of
                             the

                             related Cut-off Date and will bear interest in the
                             aggregate at a rate equal to the interest rate
                             borne by the underlying Loans (the "Loan Rate") net
                             of the aggregate servicing fees and any other
                             amounts specified in the related Prospectus
                             Supplement (the "Pass-Through Rate") or at such
                             other interest rate as may be specified in such
                             Prospectus Supplement. If specified in the related
                             Prospectus Supplement, the aggregate original

                             determined based on the cash flow on the Trust Fund
                             Assets.
 
                             The rate at which interest will be passed through
                             or paid to holders of each class of Securities
                             entitled thereto may be a fixed rate or a rate that
                             is subject to change from time to time from the
                             time and for the periods, in each case, as
                             specified in the related Prospectus Supplement. Any
                             such rate may be calculated on a loan-by-loan,
                             weighted average or notional amount, as applicable,
                             in each case as described in the related Prospectus
                             Supplement.
 
Credit Enhancement.........  The assets in a Trust Fund or the Securities of one

                             benefit of one or more types of credit enhancement
                             as described in the related Prospectus Supplement.
                             The protection against losses afforded by any such
                             credit support may be limited. The type,
                             characteristics and amount of credit enhancement
                             will be determined based on the characteristics of
                             the Trust Fund Assets and other factors and will be
                             established on the basis of requirements of each
                             Rating Agency rating the Securities of such Series.

                             the holders of the Subordinated Securities of a
                             Series to receive distributions with respect to the
                             assets in the related Trust Fund will be
                             subordinated to such rights of the holders of the
                             Senior Securities of the same Series to the extent
                             described in the related Prospectus Supplement.
                             This subordination is intended to enhance the
                             likelihood of regular receipt by holders of Senior
                             Securities of the full amount of monthly payments
                             of principal and interest due them. The protection
                             afforded to the holders of Senior Securities of a
                             Series by means of the subordination feature will
                             be accomplished by (i) the preferential right of
                             such holders to receive, prior to any distribution
                             being made in respect of the related Subordinated
                             Securities, the amounts of interest and/or
                             principal due them on each Distribution Date out of
                             the funds available for distribution on such date
                             in the related Security Account and, to the extent
                             described in the related Prospectus Supplement, by
                             the right of such holders to receive future
                             distributions on the assets in the related Trust
                             Fund that would otherwise have been payable to the
                             holders of Subordinated Securities; (ii) reducing
                             the ownership interest (if applicable) of the
                             related Subordinated Securities; (iii) a
                             combination of clauses (i) and (ii) above; or (iv)
                             as otherwise described in the related Prospectus
                             Supplement. If so specified in the related
                             Prospectus Supplement, subordination may apply only
                             in the event of certain types of losses not covered
                             by other forms of credit support, such as hazard
                             losses not covered by standard hazard insurance
                             policies or losses due to the bankruptcy or fraud
                             of the borrower. The related Prospectus Supplement

                             things, the amount of subordination of a class or
                             classes of Subordinated Securities in a Series, the
                             circumstances in which such subordination will be
                             applicable, and the manner, if any, in which the
                             amount of subordination will decrease over time.
 
B. Reserve Account.........  One or more reserve accounts or other cash accounts
                             (each, a "Reserve Account") may be established and
                             maintained for each Series of Securities. The
                             related Prospectus Supplement will specify whether
                             or not such Reserve Accounts will be included in
                             the corpus of the Trust Fund for such Series and
                             will also specify the manner of funding such
                             Reserve Accounts and the conditions under which the
                             amounts in any such Reserve Accounts will be used
                             to make distributions to holders of Securities of a
                             particular class or released from such Reserve
                             Accounts.
 
C. Letter of Credit........  If so specified in the related Prospectus
                             Supplement, credit support may be provided by one
                             or more letters of credit. A letter of credit may
                             provide limited protection against certain losses
                             in addition to or in lieu of other credit support,
                             such as, in the case of Loans, losses resulting
                             from delinquent payments, losses from risks not
                             covered by standard hazard insurance policies,
                             losses due to bankruptcy of a borrower and
                             application of certain provisions of the federal
                             Bankruptcy Code, and losses due to denial of
                             insurance coverage due to misrepresentations made
                             in connection with the origination or sale of a
                             Loan. The issuer of the letter of credit (the "L/C
                             Bank") will be obligated to honor demands with
                             respect to such letter of credit, to the extent of
                             the amount available thereunder to provide funds
                             under the circumstances and subject to such
                             conditions as are specified in the related
                             Prospectus Supplement. The liability of the L/C
                             Bank under its letter of credit will be reduced by
                             the amount of unreimbursed payments thereunder.
 
                             The maximum liability of a L/C Bank under its
                             letter of credit will be an amount equal to a
                             percentage specified in the related Prospectus
                             Supplement of the initial aggregate outstanding
                             principal balance of the Loans in the related Trust
                             Fund or one or more Classes of Securities of the
                             related Series (the "L/C Percentage"). The maximum
                             amount available at any time to be paid under a
                             letter of credit will be determined in the manner
                             specified therein and in the related Prospectus
                             Supplement.

                             bond issued by one or more insurance companies or
                             sureties. Such certificate guarantee insurance or
                             surety bond will guarantee timely distributions of
                             interest and/or full distributions of principal on
                             the basis of a schedule of principal distributions

                             in the related Prospectus Supplement. If specified
                             in the related Prospectus Supplement, one or more

                             policies, other insurance or third-party guarantees
                             may be used to provide coverage for the risks of
                             default or types of losses set forth in such
                             Prospectus Supplement.
 
E. Over-Collateralization... If so provided in the Prospectus Supplement for a
                             Series of Securities, a portion of the interest
                             payment on each Loan may be applied as an

                             additional distribution in respect of principal to
                             reduce the principal balance of a certain class or
                             classes of Securities and, thus, accelerate the
                             rate of payment of principal on such class or
                             classes of Securities.
 
F. Loan Pool
     Insurance Policy......  A mortgage pool insurance policy or policies may be
                             obtained and maintained for Loans relating to any
                             Series of Securities, which shall be limited in
                             scope, covering defaults on the related Loans in an
                             initial amount equal to a specified percentage of
                             the aggregate principal balance of all Loans
                             included in the Pool as of the related Cut-off
                             Date.

                             all or a portion of the Loans relating to any
                             Series of Securities may be (i) insured by the
                             Federal Housing Administration (the "FHA") and/or

                             Veterans' Affairs (the "VA"). See "Certain Legal
                             Aspects of the Loans -- The Title I Program."
 
H. Cross-Collateralization...If specified in the related Prospectus Supplement,
                             separate classes of a Series of Securities may
                             evidence the beneficial ownership of, or be secured
                             by, separate groups of assets included in a Trust
                             Fund. In such case, credit support may be provided
                             by a cross- collateralization feature which
                             requires that distributions be made with respect to
                             Securities evidencing a beneficial ownership
                             interest in, or secured by, one or more asset
                             groups prior to distributions to Subordinated
                             Securities evidencing a beneficial ownership
                             interest in, or secured by, other asset groups
                             within the same Trust Fund. See "Credit
                             Enhancement -- Cross-Collateralization."
 
                             If specified in the related Prospectus Supplement,
                             the coverage provided by one or more forms of
                             credit support may apply concurrently to two or
                             more separate Trust Funds. If applicable, the
                             related Prospectus Supplement will identify the
                             Trust Funds to which such credit support relates
                             and the manner of determining the amount of the
                             coverage provided to such Trust Funds thereby and
                             of the application of such coverage to the
                             identified Trust Funds. See "Credit
                             Enhancement -- Cross-Collateralization."
 
I. Other Arrangements......  Other arrangements as described in the related
                             Prospectus Supplement including, but not limited
                             to, one or more bankruptcy bonds, special hazard
                             insurance policies, other insurance or third-party
                             guarantees, interest rate swap agreements, interest
                             rate cap agreements or other similar arrangements
                             will be described in the related Prospectus
                             Supplement. An interest rate swap agreement
                             involves an agreement between two parties under
                             which one party makes to the other party periodic
                             payments based on a fixed rate of interest and
                             receives in return periodic payments based on a
                             variable rate of interest, which rates of interest
                             are calculated on the basis of a specified notional
                             amount of principal for a specified period of time
                             as will be described in the related Prospectus
                             Supplement. An interest rate cap agreement involves
                             an agreement between two parties in which one party
                             agrees to make payments to the other party when a
                             designated market interest rate goes above a
                             designated level on predetermined dates or during a
                             specified time period as will be described in the
                             related Prospectus Supplement.
 
Advances...................  The Master Servicer and, if applicable, each
                             mortgage servicing institution that services a Loan
                             in a Pool on behalf of the Master Servicer
 
                                       12
<PAGE>   14
 
                             (each, a "Sub-Servicer") may be obligated to
                             advance amounts (each, an "Advance") corresponding
                             to delinquent interest and/or principal payments on
                             such Loan (including, in the case of Cooperative
                             Loans, unpaid maintenance fees or other charges
                             under the related proprietary lease), net of the
                             Servicing Fee if so specified in the related
                             Prospectus Supplement, until the date, as specified
                             in the related Prospectus Supplement, following the
                             date on which the related Property is sold at a
                             foreclosure sale or the related Loan is otherwise
                             liquidated. Any obligation to make Advances may be
                             subject to limitations as specified in the related
                             Prospectus Supplement. If so specified in the
                             related Prospectus Supplement, Advances may be
                             drawn from a cash account available for such
                             purpose as described in such Prospectus Supplement.
                             Advances will be reimbursable to the extent
                             described under "Description of the
                             Securities -- Advances" herein and in the related
                             Prospectus Supplement.
 
                             In the event the Master Servicer or Sub-Servicer
                             fails to make a required Advance, the Trustee may
                             be obligated to advance such amounts otherwise
                             required to be advanced by the Master Servicer or
                             Sub-Servicer. See "Description of the
                             Securities -- Advances."
 
Optional Termination.......  The Master Servicer or the party specified in the
                             related Prospectus Supplement, including the holder
                             of the residual interest in a REMIC, may have the
                             option to effect early retirement of a Series of
                             Securities through the purchase of the Trust Fund
                             Assets. The Master Servicer will deposit the
                             proceeds of any such purchase in the Security
                             Account for each Trust Fund as described under "The
                             Agreements -- Payments on Loans; Deposits to
                             Security Account." Any such purchase of Trust Fund
                             Assets and property acquired in respect of Trust
                             Fund Assets evidenced by a Series of Securities
                             will be made at the option of the Master Servicer,
                             such other person or, if applicable, such holder of
                             the REMIC residual interest, at a price specified
                             in the related Prospectus Supplement. The exercise
                             of such right will effect early retirement of the
                             Securities of that Series, but the right of the
                             Master Servicer, such other person, or, if
                             applicable, such holder of the REMIC residual
                             interest, to so purchase is subject to the
                             principal balance of the related Trust Fund Assets
                             being less than the percentage specified in the
                             related Prospectus Supplement of the aggregate
                             principal balance of the Trust Fund Assets at the
                             Cut-off Date for the Series. Upon such requirement
                             being satisfied, the parties specified in the
                             related Prospectus Supplement may purchase all
                             Trust Fund Assets and thereby effect retirement of
                             such Series of Securities. In such event, the
                             applicable purchase price will be sufficient to pay
                             the aggregate outstanding principal balance of such
                             Series of Securities and any undistributed
                             shortfall in interest of such Series of Securities
                             as will be described in the related Prospectus
                             Supplement. The foregoing is subject to the
                             provision that if a REMIC election is made with
                             respect to a Trust Fund, any repurchase pursuant to
                             clause (ii) above will be made only in connection
                             with a "qualified liquidation" within the meaning
                             of Section 860F(g)(4) of the Code.
 
Legal Investment...........  The Prospectus Supplement for each series of
                             Securities will specify which, if any, of the
                             classes of Securities offered thereby constitute
                             "mortgage related securities" for purposes of the
                             Secondary Mortgage Market Enhancement Act of 1984
                             ("SMMEA"). Classes of Securities

<PAGE>   15
 
                             that qualify as "mortgage related securities" will
                             be legal investments for certain types of
                             institutional investors to the extent provided in
                             SMMEA, subject, in any case, to any other
                             regulations which may govern investments by such
                             institutional investors. Institutions whose
                             investment activities are subject to review by
                             federal or state authorities should consult with
                             their counsel or the applicable authorities to
                             determine whether an investment in a particular
                             class of Securities (whether or not such class
                             constitutes a "mortgage related security") complies
                             with applicable guidelines, policy statements or
                             restrictions. See "Legal Investment."
 
Federal Income Tax
  Consequences.............  The federal income tax consequences to
                             Securityholders will vary depending on whether one
                             or more elections are made to treat the Trust Fund
                             or specified portions thereof as a REMIC under the
                             provisions of the Internal Revenue Code of 1986, as
                             amended (the "Code"). The Prospectus Supplement for
                             each Series of Securities will specify whether such
                             an election will be made. If a REMIC election is
                             made, Securities representing regular interests in
                             a REMIC will generally be taxable to holders in the
                             same manner as evidences of indebtedness issued by
                             the REMIC. Stated interest on such regular
                             interests will be taxable as ordinary income and
                             taken into account using the accrual method of
                             accounting, regardless of the holder's normal
                             accounting method. If no REMIC election is made,
                             interest (other than original issue discount
                             ("OID")) on Securities that are characterized as
                             indebtedness for federal income tax purposes will
                             be includible in income by holders thereof in
                             accordance with their usual method of accounting.
                             Certain classes of Securities may be issued with
                             OID. A holder should be aware that the Code and the
                             Treasury regulations promulgated thereunder do not
                             adequately address certain issues relevant to
                             prepayable securities, such as the Securities.
                             Holders that will be required to report income with
                             respect to the related Securities under the accrual
                             method of accounting will do so without giving
                             effect to delays and reductions in distributions
                             attributable to a default or delinquency on the
                             Trust Fund Asset, except possibly to the extent
                             that it can be established that such amounts are
                             uncollectible. As a result, the amount of income
                             (including OID) reported by a holder of a Security
                             in any period could significantly exceed the amount
                             of cash distributed to such holder in that period.
 
                             If a REMIC election is made with respect to a
                             Series of Securities, then, upon the issuance of
                             those Securities, special counsel to the Depositor
                             will issue an opinion generally to the effect that
                             the arrangement by which such Securities are issued
                             will be treated as a REMIC as long as all of the
                             provisions of the applicable Agreement are complied
                             with and the statutory and regulatory requirements
                             are satisfied. Such Securities will be designated
                             as "regular interests" or "residual interests" in a
                             REMIC. A REMIC will not be subject to entity-level
                             tax. Rather, the taxable income or net loss of a
                             REMIC will be taken into account by the holders of
                             residual interests. Such holders will report their
                             proportionate share of the taxable income of the
                             REMIC whether or not they receive cash
                             distributions from the REMIC attributable to such
                             income. A portion (or, in some cases, all) of the
                             income from a residual interest (i) may not be
                             subject to offset by losses from other activities,
                             (ii) for a holder that is subject to tax under the
                             Code on unrelated business taxable

                             income, may be treated as unrelated business
                             taxable income and (iii) for a foreign holder, may
                             not qualify for exemption from or reduction of
                             withholding. In addition, (i) residual interests
                             are subject to transfer restrictions and (ii)
                             certain transfers of residual interests will not be
                             recognized for federal income tax purposes.
                             Further, individual holders are subject to
                             limitations on the deductibility of expenses of the
                             REMIC.
 
                             If so specified in the Prospectus Supplement for a
                             Series of Securities, then, upon the issuance of
                             those Securities, special counsel to the Depositor
                             will issue an opinion generally to the effect that
                             the arrangement by which such Securities are issued
                             will be classified as a grantor trust under Subpart
                             E, Part I of Subchapter J of the Code and not as an
                             association taxable as a corporation. If so
                             provided in the Prospectus Supplement for a Series
                             of Securities representing interests in Trust Fund
                             Assets, holders of Securities of such Series will
                             be treated as owning directly rights to receive
                             certain payments of interest or principal, or both,
                             on the assets held in the Trust Fund for such
                             Series. All income with respect to a Stripped
                             Security will be accounted for as OID and, unless
                             otherwise specified in the related Prospectus
                             Supplement, will be reported by the Trustee on an
                             accrual basis, which may be prior to the receipt of
                             cash associated with such income.
 
                             If so specified in the Prospectus Supplement for a
                             Series of Securities, special counsel to the
                             Depositor will issue an opinion generally to the
                             effect that the Trust Fund will not be treated as
                             an association or a publicly traded partnership
                             taxable as a corporation as long as all of the
                             provisions of the applicable Agreement are complied
                             with and the statutory and regulatory requirements
                             are satisfied. If Notes are issued by such Trust
                             Fund, such Notes will be treated as indebtedness
                             for federal income tax purposes. The holders of the
                             Certificates issued by such Trust Fund, if any,
                             will agree to treat the Certificates as equity
                             interests in a partnership.
 
                             Generally, gain or loss will be recognized on a
                             sale of Securities in the amount equal to the
                             difference between the amount realized and the
                             seller's tax basis in the Securities sold. The
                             material federal income tax consequences for
                             investors associated with the purchase, ownership
                             and disposition of the Securities are set forth
                             herein under "Federal Income Tax Consequences." The
                             material federal income tax consequences for
                             investors associated with the purchase, ownership
                             and disposition of Securities of any particular
                             Series will be set forth under the heading "Federal
                             Income Tax Consequences" in the related Prospectus
                             Supplement. See "Federal Income Tax Consequences."
 
ERISA Considerations.......  A fiduciary of any employee benefit plan or other
                             retirement plan or arrangement subject to the
                             Employee Retirement Income Security Act of 1974, as
                             amended ("ERISA"), or the Code should carefully
                             review with its legal advisors whether the purchase
                             or holding of Securities could give rise to a
                             transaction prohibited or not otherwise permissible
                             under ERISA or the Code. Certain exemptions from
                             the prohibited transaction rules could be
                             applicable to the acquisition of the Securities.
                             See "ERISA Considerations." The U.S. Department of
                             Labor has issued an individual exemption,
                             Prohibited Transaction Exemption 90-24, to Morgan
                             Stanley & Co. Incorporated that generally exempts
                             from the

                             application of certain of the prohibited
                             transaction provisions of ERISA and the Code,
                             transactions relating to the purchase, sale and
                             holding of pass-through certificates underwritten
                             by such underwriter such as certain classes of the
                             Securities and the servicing and operation of asset
                             pools, provided that certain conditions are
                             satisfied as will be described in the related
                             Prospectus Supplement. Certain classes of
                             Securities may not be transferred unless the
                             Trustee and the Depositor are furnished with a
                             letter of representation or an opinion of counsel
                             to the effect that such transfer will not result in
                             a violation of the prohibited transaction
                             provisions and will not subject the Trustee, the
                             Depositor or the Master Servicer to additional
                             obligations. See "Description of the Securities --
                             General" and "ERISA Considerations."
 
Rating.....................  It will be a requirement for issuance of any Series
                             that the Securities offered by this Prospectus and
                             the related Prospectus Supplement be rated by at
                             least one Rating Agency in one of its four highest
                             applicable rating categories. The rating or ratings
                             applicable to Securities of each Series offered
                             hereby and by the related Prospectus Supplement
                             will be as set forth in the related Prospectus
                             Supplement. A securities rating should be evaluated
                             independently of similar ratings on different types
                             of securities. A securities rating does not address
                             the effect that the rate of prepayments on Loans
                             for a Series may have on the yield to investors in
                             the Securities of such Series. See "Risk
                             Factors -- Ratings are not Recommendations."
 
Risk Factors...............  For a discussion of certain risks associated with
                             an investment in the Securities, see "Risk Factors"
                             on page 17 herein and in the related Prospectus
                             Supplement.

<PAGE>   18
 
                                  RISK FACTORS
 
     Investors should consider the following factors in connection with the
purchase of the Securities.
 
LACK OF SECONDARY MARKET LIMITS LIQUIDITY
 
     There will be no market for the Securities of any Series prior to the
issuance thereof, and there can be no assurance that a secondary market will
develop or, if it does develop, that it will provide Securityholders with
liquidity of investment or will continue for the life of the Securities of such
Series. Morgan Stanley & Co. Incorporated, through one or more of its
affiliates, and the other underwriters, if any, specified in the related
Prospectus Supplement, presently expect to make a secondary market in
securities, but have no obligation to do so.
 
LIMITED SOURCES OF PAYMENTS -- NO RECOURSE TO SELLERS, DEPOSITOR OR MASTER
SERVICER
 
     The Depositor does not have, nor is it expected to have, any significant
assets. Unless otherwise specified in the related Prospectus Supplement, the
Securities of a Series will be payable solely from the Trust Fund for such
Securities and will not have any claim against or security interest in the Trust
Fund for any other Series. There will be no recourse to the Depositor or any
other person for any failure to receive distributions on the Securities.
Further, at the times set forth in the related Prospectus Supplement, certain
Trust Fund Assets and/or any balance remaining in the Security Account
immediately after making all payments due on the Securities of such Series,
after making adequate provision for future payments on certain classes of
Securities and after making any other payments specified in the related
Prospectus Supplement, may be promptly released or remitted to the Depositor,
the Master Servicer, any credit enhancement provider or any other person
entitled thereto and will no longer be available for making payments to
Securityholders. Consequently, holders of Securities of each Series must rely
solely upon payments with respect to the Trust Fund Assets and the other assets
constituting the Trust Fund for a Series of Securities, including, if
applicable, any amounts available pursuant to any credit enhancement for such
Series, for the payment of principal of and interest on the Securities of such
Series.
 
     The Securities will not represent an interest in or obligation of the
Depositor, the Master Servicer, any Seller or any of their respective
affiliates. The only obligations, if any, of the Depositor with respect to the
Trust Fund Assets or the Securities of any Series will be to obtain certain
representations and warranties from each Seller or each originator (the
"Originator") of the Trust Fund Assets and to assign to the Trustee for the
related Series of Securities the Depositor's rights with respect to such
representations and warranties. The Depositor does not have, and is not expected
in the future to have, any significant assets with which to meet any obligation
to repurchase Trust Fund Assets with respect to which there has been a breach of
any representation or warranty. If, for example, the Depositor were required to
repurchase a Trust Fund Asset, its only sources of funds to make such repurchase
would be from funds obtained (i) from the enforcement of a corresponding
obligation, if any, on the part of the related Seller or Originator of such
Trust Fund Asset, or (ii) to the extent provided in the related Prospectus
Supplement, from a Reserve Account or similar credit enhancement established to
provide funds for such repurchases. The only obligations of the Master Servicer,
other than its master servicing obligations, with respect to the Trust Fund
Assets or the Securities of any Series will be pursuant to certain
representations and warranties. The Master Servicer may be required to
repurchase or substitute for any Trust Fund Asset with respect to which such
representations and warranties are breached. There is no assurance, however,
that the Master Servicer will have the financial ability to effect any such
repurchase or substitution.
 
     The only obligations of any Seller or Originator with respect to Trust Fund
Assets or the Securities of any Series will be pursuant to certain
representations and warranties and certain document delivery requirements. A
Seller or Originator may be required to repurchase or substitute for any Trust
Fund Asset with respect to which such representations and warranties or document
delivery requirements are breached. There is no assurance, however, that such
Seller or Originator will have the financial ability to effect such repurchase
or substitution.

LIMITATIONS ON CREDIT ENHANCEMENT FOR PROTECTION AGAINST LOSSES
 
     Limitation Regarding Types of Losses Covered.  Although credit enhancement
is intended to reduce the risk of delinquent payments or losses to holders of
Securities entitled to the benefit thereof, the amount of such credit
enhancement will be limited, as set forth in the related Prospectus Supplement,
and may be subject to periodic reduction in accordance with a schedule or
formula or otherwise decline, and could be depleted under certain circumstances
prior to the payment in full of the related Series of Securities, and as a
result Securityholders of the related Series may suffer losses. Moreover, such
credit enhancement may not cover all potential losses or risks. For example,
credit enhancement may or may not cover fraud or negligence by a loan originator
or other parties. In addition, the Trustee will generally be permitted to
reduce, terminate or substitute all or a portion of the credit enhancement for
any Series of Securities, provided the applicable Rating Agency indicates that
the then-current rating of the Securities of such Series will not be adversely
affected. See "Credit Enhancement."
 
     Disproportionate Benefits to Certain Classes and Series.  A Series of
Securities may include one or more classes of Subordinated Securities, if
provided in the related Prospectus Supplement. Although subordination is
intended to reduce the likelihood of temporary shortfalls and ultimate losses to
holders of the related Senior Securities, the amount of subordination will be
limited and may decline under certain circumstances. In addition, if principal
payments on one or more classes of Securities of a Series are made in a
specified order of priority, any related credit enhancement may be exhausted
before the principal of the later paid classes of Securities of such Series has
been repaid in full. As a result, the impact of losses and shortfalls
experienced with respect to the Trust Fund Assets may fall primarily upon those
classes of Securities having a latter right of payments. Moreover, if a form of
credit enhancement covers the Securities of more than one Series and losses on
the related Trust Fund Assets exceed the amount of such credit enhancement, it
is possible that the holders of Securities of one (or more) such Series will be
disproportionately benefited by such credit enhancement to the detriment of the
holders of Securities of one (or more) other such Series. The amount of any
applicable credit enhancement supporting one or more other classes of Securities
will be determined on the basis of criteria established by each Rating Agency
rating such classes of Securities as described below under "-- Ratings are not
Recommendations."
 
     Limitations on FHA Insurance for Title I Loans.  The related Prospectus
Supplement will specify the number and percentage of Title I Loans, if any,
included in the related Trust Fund that are partially insured by the FHA
pursuant to the Title I Program. Since the FHA insurance amount for the Title I
Loans is limited as described herein under "Certain Legal Aspects of the
Loans -- The Title I Program" and in the related Prospectus Supplement, and
since the adequacy of such FHA insurance is dependent upon future events,
including reductions for the payment of FHA claims, no assurance can be given
that the FHA insurance is or will be adequate to cover 90% of all potential
losses on the Title I Loans included in the related Trust Fund. If the FHA
insurance for the Title I Loans is reduced to zero, such Loans will be
effectively uninsured from and after the date of such reduction. Under the Title
I Program, until a claim for insurance reimbursement is submitted to the FHA,
the FHA does not review or approve for qualification for insurance the
individual Title I Loan insured thereunder (as is typically the case with other
federal loan insurance programs). Consequently, the FHA has not acknowledged
that any of the Title I Loans are eligible for FHA insurance, nor has the FHA
reviewed or approved the underwriting and qualification by the originating
lenders of any individual Title I Loan. See "Certain Legal Aspects of the
Loans -- The Title I Program."
 
     The availability of FHA reimbursement following a default on a Title I Loan
is subject to a number of conditions, including strict compliance by the
originating lender of such loan, the Seller, the FHA claims administrator, the
Master Servicer and any subservicer with the FHA regulations in originating and
servicing such Title I Loan, and limits on the aggregate insurance coverage
available in the lender's insurance company reserve account. For example, the
FHA Regulations provide that, prior to originating a Title I Loan, a Title I
lender must exercise prudence and diligence in determining whether the borrower
and any co-maker or co-signer is solvent and an acceptable credit risk with a
reasonable ability to make payments on the loan. Although the related Seller
will represent and warrant that the Title I Loans have been originated and
serviced in compliance with all FHA regulations, these regulations are
susceptible to substantial interpretation. Failure to comply with all FHA
regulations may result in a denial of FHA claims, and there can be no assurance
that
 
                                       18
<PAGE>   20
 
the FHA's enforcement of the FHA regulations will not become more strict in the
future. See "Certain Legal Aspects of the Loans -- The Title I Program."
 
BASIS RISK AND POSSIBLE INTEREST SHORTFALLS
 
     The Trust Fund Assets may accrue interest at variable rates based on
changes in specified indexes (as set forth in the related Prospectus Supplement)
which may adjust monthly, quarterly, annually or otherwise. The Securities,
however, may accrue interest at interest rates based on different indexes and
may adjust on different periods. As a result, there may be periods during which
the weighted average rate of interest at which the Trust Fund Assets are
accruing interest is less than the rate of interest on the Securities. The
resulting shortfall in interest collections on the Trust Fund Assets vis-a-vis
the amount of interest owed on the Securities will, unless otherwise specified
in the related Prospectus Supplement, be borne by the holders of such
Securities.
 
PREPAYMENT AND YIELD CONSIDERATIONS AND REINVESTMENT RISK
 
     Prepayment and Yield considerations; Yield May Vary.  The timing of
principal payments of the Securities of a Series will be affected by a number of
factors, including the following: (i) the rate, timing and extent of prepayments
(including for this purpose prepayments resulting from refinancing or
liquidations of the Loans due to defaults, casualties, condemnations and
repurchases by the Depositor or the Master Servicer) of the Loans comprising the
Trust Fund, which prepayments may be influenced by a variety of factors,
including general economic conditions, prevailing interest rate levels, the
availability of alternative financing and homeowner mobility, (ii) the manner of
allocating principal and/or payments among the classes of Securities of a Series
as specified in the related Prospectus Supplement, (iii) the exercise by the
party entitled thereto of any right of optional termination and (iv) the rate
and timing of payment defaults and losses incurred with respect to the Trust
Fund Assets. The repurchase of Loans by a Seller, an Originator or the Master
Servicer may result from repurchases of Trust Fund Assets due to material
breaches of such Seller's, such Originator's or the Master Servicer's
representations and warranties, as applicable. The yields to maturity and
weighted average lives of the Securities will be affected primarily by the rate
and timing of prepayment of the Loans comprising the Trust Fund Assets. The
"yield to maturity" is the rate of return an investor in a Security will receive
if such Security is held to its maturity date taking into account the purchase
price, redemption value, time to maturity, interest rate borne by such Security
and the time between interest payments. The "weighted average life" of a
Security refers to the amount of time that would elapse from the date of its
issuance until each dollar applicable to principal of such Security is
distributed to the investor. The yields to maturity and weighted average lives
of the Securities will also be affected by the distribution of amounts remaining
in any Pre-Funding Account following the end of the related Funding Period. A
delay in distributions of principal resulting in an extension of the weighted
average life of a Security or an acceleration in distributions of principal
resulting in a reduction of the weighted average life of a Security may
adversely impact the yield to maturity anticipated by an investor in such
Security. See "Yield and Prepayment Considerations" and "The
Agreements -- Pre-Funding Account."
 
     Reinvestment Risk Due to Prepayment of Loans.  Any reinvestment risks
resulting from a faster or slower incidence of prepayment of Loans held by a
Trust Fund will be borne entirely by the holders of one or more classes of the
related Series of Securities. Amounts received by an investor from distributions
on a Security may be reinvested at prevailing interest rates which may be higher
or lower than the interest rate payable on the Securities. In general, if
prevailing interest rates fall significantly below the Loan Rates borne by the
Loans, such Loans are more likely to be subject to higher prepayment rates than
if prevailing interest rates remain at or above such Loan Rates. If, however,
prevailing interest rates rise appreciably above the Loan Rates borne by the
Loans, such Loans are more likely to experience a lower prepayment rate than if
prevailing rates remain at or below such Loan Rates. Thus, an investor may
receive accelerated principal payments on the Securities held by the investor
for reinvestment at a time when prevailing interest rates are lower than the
interest rate payable on such Securities. Conversely, an investor may not
receive any prepayments on such Securities at a time when any such prepayments
could be reinvested at interest rates
 
                                       19
<PAGE>   21
 
higher than those payable on the Securities. See "Yield and Prepayment
Considerations" and "The Agreements -- Pre-Funding Account."
 
     Interest payable on the Securities of a Series on a Distribution Date will
include all interest accrued during the period specified in the related
Prospectus Supplement. In the event interest accrues over a period ending two or
more days prior to a Distribution Date, the effective yield to Securityholders
will be reduced from the yield that would otherwise be obtainable if interest
payable on the Securities were to accrue through the day immediately preceding
each Distribution Date, and the effective yield (at par) to Securityholders will
be less than the indicated coupon rate. See "Description of the
Securities -- Distributions on Securities -- Distributions of Interest."
 
GREATER RISK CONSIDERATIONS DUE TO GEOGRAPHIC CONCENTRATION
 
     Certain geographic regions of the United States from time to time will
experience weaker regional economic conditions and housing markets, and,
consequently, will experience higher rates of loss and delinquency on loans
generally. Any concentration of the Loans relating to any Series of Securities
in any such region may present risk considerations in addition to those
generally present for similar loan-backed securities without such concentration.
See "The Mortgage Pool" in the related Prospectus Supplement for further
information regarding the geographic concentration of the Loans underlying the
Securities of any Series.
 
NATURE OF SECURITY MAY AFFECT PAYMENTS ON LOANS
 
     Low Credit Quality Borrowers May Affect Payments.  Certain of the Loans
underlying a Series of Securities may have been made to lower credit quality
borrowers who have marginal credit and fall into one of two categories:
customers with moderate income, limited assets and other income characteristics
which cause difficulty in borrowing from banks and other traditional lending
sources, and customers with a derogatory credit report, including a history of
irregular employment, previous bankruptcy filings, repossession of property,
charged-off loans and garnishment of wages. The average Loan Rate on those Loans
made to these types of borrowers is generally higher than that charged by
lenders that typically impose more stringent credit requirements. The payment
experience on loans made to these types of borrowers is likely to be different
from that on loans made to borrowers with higher credit quality, and is likely
to be more sensitive to changes in the economic climate in the areas in which
such borrowers reside.
 
     Balloon Payments May Affect Payments.  Certain of the Loans as of the
related Cut-off Date may not be fully amortizing over their terms to maturity
and, thus, will require substantial principal payments (i.e., balloon payments)
at their stated maturity. Loans with balloon payments involve a greater degree
of risk because the ability of a borrower to make a balloon payment typically
will depend upon its ability either to timely refinance the loan or to timely
sell the related Property. The ability of a borrower to accomplish either of
these goals will be affected by a number of factors, including the level of
available mortgage rates at the time of sale or refinancing, the borrower's
equity in the related Property, the financial condition of the borrower and tax
laws. Losses on such Loans that are not otherwise covered by the credit
enhancement described in the applicable Prospectus Supplement will be borne by
the holders of one or more classes of Securities of the related Series.
 
     Property Values May be Insufficient.  There are several factors that could
adversely affect the value of Properties such that the outstanding balance of
the related Loans, together with any senior financing on the Properties, if
applicable, would equal or exceed the value of the Properties. Among the factors
that could adversely affect the value of the Properties are an overall decline
in the residential real estate market in the areas in which the Properties are
located or a decline in the general condition of the Properties as a result of
failure of borrowers to maintain adequately the Properties or of natural
disasters that are not necessarily covered by insurance, such as earthquakes and
floods. In the case of Home Equity Loans, such decline could extinguish the
value of the interest of a junior mortgagee in the Property before having any
effect on the interest of the related senior mortgagee. If such a decline
occurs, the actual rates of delinquencies, foreclosures and losses on all Loans
could be higher than those currently experienced in the mortgage lending
industry in general. Losses on such Loans that are not otherwise covered by the
credit enhancement described in the
 
                                       20
<PAGE>   22
 
applicable Prospectus Supplement will be borne by the holders of one or more
classes of Securities of the related Series.
 
     Delays in Liquidation and Receipt of Proceeds Due to Litigation.  Even
assuming that the Properties provide adequate security for the Loans,
substantial delays could be encountered in connection with the liquidation of
defaulted Loans and corresponding delays in the receipt of related proceeds by
Securityholders could occur. An action to foreclose on a Property securing a
Loan is regulated by state statutes and rules and is subject to many of the
delays and expenses of other lawsuits if defenses or counterclaims are
interposed, sometimes requiring several years to complete. Furthermore, in some
states an action to obtain a deficiency judgment is not permitted following a
nonjudicial sale of a Property. In the event of a default by a borrower, these
restrictions, among other things, may impede the ability of the Master Servicer
to foreclose on or sell the Property or to obtain liquidation proceeds
sufficient to repay all amounts due on the related Loan. In addition, the Master
Servicer will be entitled to deduct from related liquidation proceeds all
expenses reasonably incurred in attempting to recover amounts due on defaulted
Loans and not yet repaid, including payments to senior lienholders, legal fees
and costs of legal action, real estate taxes and maintenance and preservation
expenses.
 
     Disproportionate Effect of Liquidation Expenses May Affect
Proceeds.  Liquidation expenses with respect to defaulted loans do not vary
directly with the outstanding principal balance of the loan at the time of
default. Therefore, assuming that a servicer took the same steps in realizing
upon a defaulted loan having a small remaining principal balance as it would in
the case of a defaulted loan having a large remaining principal balance, the
amount realized after expenses of liquidation would be smaller as a percentage
of the outstanding principal balance of the small loan than would be the case
with the defaulted loan having a large remaining principal balance.
 
     Home Equity Loans; Junior Loans Create Additional Risk of Loss.  Since the
mortgages and deeds of trust securing the Home Equity Loans will be primarily
junior liens subordinate to the rights of the mortgagee under the related senior
mortgage(s) or deed(s) of trust, the proceeds from any liquidation, insurance or
condemnation proceeds will be available to satisfy the outstanding balance of
such junior lien only to the extent that the claims of such senior mortgagees
have been satisfied in full, including any related foreclosure costs. In
addition, a junior mortgagee may not foreclose on the property securing a junior
mortgage unless it forecloses subject to any senior mortgage, in which case it
must either pay the entire amount due on any senior mortgage to the related
senior mortgagee at or prior to the foreclosure sale or undertake the obligation
to make payments on any such senior mortgage in the event the mortgagor is in
default thereunder. The Trust Fund will not have any source of funds to satisfy
any senior mortgages or make payments due to any senior mortgagees and may
therefore be prevented from foreclosing on the related property.
 
     Consumer Protection Laws May Affect Loans.  Applicable state laws generally
regulate interest rates and other charges, require certain disclosures, and
require licensing of certain originators and servicers of Loans. In addition,
most states have other laws, public policy and general principles of equity
relating to the protection of consumers, unfair and deceptive practices and
practices which may apply to the origination, servicing and collection of the
Loans. Depending on the provisions of the applicable law and the specific facts
and circumstances involved, violations of these laws, policies and principles
may limit the ability of the Master Servicer to collect all or part of the
principal of or interest on the Loans, may entitle the borrower to a refund of
amounts previously paid and, in addition, could subject the Master Servicer to
damages and administrative sanctions. See "Certain Legal Aspects of the Loans."
 
     Risks Associated with Non-Owner Occupied Properties.  Certain of the
Properties relating to Loans may not be owner occupied. It is possible that the
rates of delinquencies, foreclosures and losses on Loans secured by non-owner
occupied Properties could be higher than such rates on Loans secured by the
primary residence of the borrower.
 
POTENTIAL LIABILITY FOR ENVIRONMENTAL CONDITIONS
 
     Real property pledged as security to a lender may be subject to certain
environmental risks. Under the laws of certain states, contamination of a
property may give rise to a lien on the property to assure the costs of
 
                                       21
<PAGE>   23
 
cleanup. In several states, such a lien has priority over the lien of an
existing mortgage against such property. In addition under the laws of some
states and under the federal Comprehensive Environmental Response, Compensation
and Liability Act of 1980 ("CERCLA"), a lender may be liable, as an "owner" or
"operator," for costs of addressing releases or threatened releases of hazardous
substances that require remedy at a property, if agents or employees of the
lender have become sufficiently involved in the operations of the borrower,
regardless of whether the environmental damage or threat was caused by a prior
owner. A lender also risks such liability on foreclosure of the related
property. See "Certain Legal Aspects of the Loans -- Environmental Risks."
 
SECURITY INTEREST RISKS ASSOCIATED WITH CERTAIN LOAN ASSETS
 
     Security Interests relating to Contracts Secured by Home Improvements or
Manufactured Homes. Certain Contracts may be secured by security interests in
Home Improvements or Manufactured Homes that are not considered to be real
property because they are not permanently affixed to real estate. Perfection of
security interests in such Home Improvements or Manufactured Homes and
enforcement of rights to realize upon the value of such Home Improvements or
Manufactured Homes as collateral for the Contracts are subject to a number of
Federal and state laws, including the Uniform Commercial Code as adopted in each
state and each state's certificate of title statutes. The steps necessary to
perfect the security interest in Home Improvements or a Manufactured Home will
vary from state to state. Unless otherwise specified in the related Prospectus
Supplement, the Master Servicer of a Contract will not amend any certificate of
title to change the lienholder specified therein from such Master Servicer to
the applicable Trustee and will not deliver any certificate of title to such
Trustee or note thereon such Trustee's interest. Consequently, in some states,
in the absence of such an amendment, the assignment to such Trustee of the
security interest in the Home Improvements or a Manufactured Home may not be
effective or such security interest may not be perfected and, in the absence of
such notation or delivery to such Trustee, the assignment of the security
interest in the Home Improvements or Manufactured Home may not be effective
against creditors of the Master Servicer or a trustee in bankruptcy of the
Master Servicer. While the Depositor cannot quantify the expense and
administrative burden involved by the Master Servicer taking such actions, in a
transaction with a diversified pool of Contracts consisting of a large number of
Contracts with relatively small principal balances, the expense and
administrative burden of such actions may be prohibitive. If any related credit
enhancement is exhausted and a Contract is in default, then recovery of amounts
due on such Contracts is dependent on repossession and resale of the Home
Improvements or Manufactured Home securing such Contract. Certain other factors
may limit the ability of the Master Servicer to realize upon the Home
Improvements or Manufactured Homes or may limit the amount realized to less than
the amount due.
 
     Manufactured Homes, unlike Mortgaged Properties, and Home Improvement,
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 or Home Improvement
may be lower than the principal amount outstanding under the related Contract.
The Home Improvement Contracts will be originated by a commercial bank, a
savings and loan association, a commercial mortgage banker or other financial
institution in the ordinary course of business. For more information concerning
Home Improvement Contracts and Manufactured Housing Contracts, see "The Trust
Fund -- The Loans -- Home Improvement Contracts" and "-- Manufactured Housing
Contracts."
 
     Unsecured Contracts.  The obligations of the borrower under certain
Contracts included as part of the related Trust Fund Assets may not be secured
by an interest in the related real estate or otherwise, and the related Trust
Fund, as the owner of such Loan, will be a general unsecured creditor as to such
obligations. As a consequence, in the event of a default under an unsecured
Contract, the related Trust Fund will have recourse only against the borrower's
assets generally, along with all other general unsecured creditors of the
borrower. In a bankruptcy or insolvency proceeding relating to a borrower on an
unsecured Contract, the obligations of the borrower under such Contract may be
discharged in their entirety, notwithstanding the fact that the portion of such
borrower's assets made available to the related Trust Fund as a general
unsecured creditor to pay amounts due and owing thereunder are insufficient to
pay all such amounts. A borrower on an unsecured
 
                                       22
<PAGE>   24
 
Contract may not demonstrate the same degree of concern over performance of its
obligations under such Contract as if such obligations were secured by a family
residence owned by such borrower.
 
CERTAIN FEDERAL LAWS MAY AFFECT THE LOANS
 
     Consumer Protection Laws May Affect Collections.  The Loans may also be
subject to federal laws, including:
 
          (i) the Federal Truth in Lending Act and Regulation Z promulgated
     thereunder, which require certain disclosures to the borrowers regarding
     the terms of the Loans;
 
          (ii) the Equal Credit Opportunity Act and Regulation B promulgated
     thereunder, which prohibit discrimination on the basis of age, race, color,
     sex, religion, marital status, national origin, receipt of public
     assistance or the exercise of any right under the Consumer Credit
     Protection Act, in the extension of credit;
 
          (iii) the Fair Credit Reporting Act, which regulates the use and
     reporting of information related to the borrower's credit experience; and
 
          (iv) for Loans that were originated or closed after November 7, 1989,
     the Home Equity Loan Consumer Protection Act of 1988, which requires
     additional application disclosures, limits changes that may be made to the
     loan documents without the borrower's consent and restricts a lender's
     ability to declare a default or to suspend or reduce a borrower's credit
     limit to certain enumerated events.
 
     These laws impose specific statutory liabilities upon lenders who fail to
comply with the provisions of such laws. In addition, violation of such laws may
limit the ability to collect all or a part of the principal of or interest on
the Loans and could subject assignees to damages and administrative enforcement.
See "Certain Legal Aspects of the Loans -- Consumer Protection Laws."
 
     The Riegle Act May Affect Enforceability of Loans.  Certain mortgage loans
may be subject to the Riegle Community Development and Regulatory Improvement
Act of 1994 (the "Riegle Act") which incorporates the Home Ownership and Equity
Protection Act of 1994. These provisions impose additional disclosure and other
requirements on creditors with respect to non-purchase money mortgage loans with
high interest rates or high up-front fees and charges. The provisions of the
Riegle Act apply on a mandatory basis to all mortgage loans originated on or
after October 1, 1995. These provisions can impose specific statutory
liabilities upon creditors who fail to comply with their provisions and may
affect the enforceability of the related loans. In addition, any assignee of the
creditor would generally be subject to all claims and defenses that the consumer
could assert against the creditor, including, without limitation, the right to
rescind the mortgage loan.
 
     Holder in Due Course Rules May Affect Collections.  The Contracts are also
subject to the Preservation of Consumers' Claims and Defenses regulations of the
Federal Trade Commission and other similar federal and state statutes and
regulations (collectively, the "Holder in Due Course Rules"), which protect the
homeowner from defective craftsmanship or incomplete work by a contractor. These
laws permit the obligor to withhold payment if the work does not meet the
quality and durability standards agreed to by the homeowner and the contractor.
The Holder in Due Course Rules have the effect of subjecting any assignee of the
seller in a consumer credit transaction to all claims and defenses which the
obligor in the credit sale transaction could assert against the seller of the
goods.
 
     The federal Soldiers' and Sailors' Civil Relief Act of 1940, as amended
(the "Relief Act"), may affect the ability of the Master Servicer to collect
full amounts of interest on certain Loans and could interfere with the ability
of the Master Servicer to foreclose on certain Properties. See "Certain Legal
Aspects of the Loans -- Soldiers' and Sailors' Civil Relief Act" herein.
 
     Violations of certain provisions of these federal laws may limit the
ability of the Master Servicer to collect all or part of the principal of or
interest on the Loans and in addition could subject the Trust Fund to damages
and administrative enforcement. Losses on such Loans that are not otherwise
covered by the credit
 
                                       23
<PAGE>   25
 
enhancement described in the related Prospectus Supplement will be borne by the
holders of one or more classes of Securities of the related Series. See "Certain
Legal Aspects of the Loans."
 
LIMITATIONS ON INTEREST PAYMENTS AND FORECLOSURES
 
     Generally, under the terms of the Relief Act or similar state legislation,
a mortgagor who enters military service after the origination of the related
mortgage loan (including a mortgagor who is a member of the National Guard or is
in reserve status at the time of the origination of the mortgage loan and is
later called to active duty) may not be charged interest (including fees and
charges) above an annual rate of 6% during the period of such mortgagor's active
duty status, unless a court orders otherwise upon application of the lender. It
is possible that such action could affect, for an indeterminate period of time,
the ability of the Master Servicer to collect full amounts of interest on
certain of the Loans. In addition, the Relief Act imposes limitations that would
impair the ability of the Master Servicer to foreclose on an affected Loan
during the mortgagor's period of active duty status. Thus, in the event that
such a Loan goes into default, there may be delays and losses occasioned by the
inability to realize upon the Property in a timely fashion.
 
RATINGS ARE NOT RECOMMENDATIONS
 
     It will be a condition to the issuance of a class of Securities offered
hereby that they be rated in one of the four highest rating categories by the
Rating Agency identified in the related Prospectus Supplement. Any such rating
would be based on, among other things, the adequacy of the value of the related
Trust Fund Assets and any credit enhancement with respect to such class and will
represent such Rating Agency's assessment solely of the likelihood that holders
of such class of Securities will receive payments to which such Securityholders
are entitled under the related Agreement. Such rating will not constitute an
assessment of the likelihood that principal prepayments on the related Loans
will be made, the degree to which the rate of such prepayments might differ from
that originally anticipated or the likelihood of early optional termination of
the Series of Securities. Such rating shall not be deemed a recommendation to
purchase, hold or sell Securities, inasmuch as it does not address market price
or suitability for a particular investor. Such rating will not address the
possibility that prepayment at higher or lower rates than anticipated by an
investor may cause such investor to experience a lower than anticipated yield or
that an investor purchasing a Security at a significant premium might fail to
recoup its initial investment under certain prepayment scenarios.
 
     There is also no assurance that any such rating will remain in effect for
any given period of time or that it may not be lowered or withdrawn entirely by
the Rating Agency in the future if in its judgment circumstances in the future
so warrant. In addition to being lowered or withdrawn due to any erosion in the
adequacy of the value of the Trust Fund Assets or any credit enhancement with
respect to a Series of Securities, such rating might also be lowered or
withdrawn because of, among other reasons, an adverse change in the financial or
other condition of a credit enhancement provider or a change in the rating of
such credit enhancement provider's long term debt. In the event of a reduction
in the rating of a Series of Securities, the market price of such Securities
could be adversely affected.
 
     The amount, type and nature of credit enhancement, if any, established with
respect to a class of Securities will be determined on the basis of criteria
established by each Rating Agency rating classes of such Series. Such criteria
are sometimes based upon an actuarial analysis of the behavior of similar loans
in a larger group. Such analysis is often the basis upon which each Rating
Agency determines the amount of credit enhancement required with respect to each
such class. There can be no assurance that the historical data supporting any
such actuarial analysis will accurately reflect future experience nor any
assurance that the data derived from a large pool of similar loans accurately
predicts the delinquency, foreclosure or loss experience of any particular pool
of Loans. No assurance can be given that the values of any Properties have
remained or will remain at their levels on the respective dates of origination
of the related Loans. If the residential real estate markets should experience
an overall decline in property values such that the outstanding principal
balances of the Loans in a particular Trust Fund and any secondary financing on
the related Properties become equal to or greater than the value of the
Properties, the rates of delinquencies, foreclosures and losses could be higher
than those now generally experienced in the mortgage lending industry. In
addition, adverse economic conditions (which may or may not affect real property
values) may affect the timely payment by mortgagors
 
                                       24
<PAGE>   26
 
of scheduled payments of principal and interest on the Loans and, accordingly,
the rates of delinquencies, foreclosures and losses with respect to any Trust
Fund. To the extent that such losses are not covered by credit enhancement, such
losses will be borne, at least in part, by the holders of one or more classes of
Securities of the related Series. See "Rating."
 
BOOK-ENTRY REGISTRATION MAY REDUCE LIQUIDITY
 
     If issued in book-entry form, such registration may reduce the liquidity of
the Securities in the secondary trading market since investors may be unwilling
to purchase Securities for which they cannot obtain physical certificates. Since
transactions in book-entry Securities can be effected only through The
Depository Trust Company ("DTC"), participating organizations, Financial
Intermediaries and certain banks, the ability of a Securityholder to pledge a
book-entry Security to persons or entities that do not participate in the DTC
system may be limited due to lack of a physical certificate representing such
Securities. Security Owners will not be recognized as Securityholders, as such
term is used in the related Agreement, and Security Owners will be permitted to
exercise the rights of Securityholders only indirectly through DTC and its
Participants.
 
     In addition, Securityholders may experience some delay in their receipt of
distributions of interest and principal on book-entry Securities since
distributions are required to be forwarded by the Trustee to DTC and DTC will
then be required to credit such distributions to the accounts of Depository
participants which thereafter will be required to credit them to the accounts of
Securityholders either directly or indirectly through Financial Intermediaries.
See "Description of the Securities--Book-Entry Registration of Securities."
 
REINVESTMENT RISK RELATED TO PRE-FUNDING ACCOUNTS
 
     If so provided in the related Prospectus Supplement, on the related Closing
Date the Depositor will deposit cash from the proceeds of the issuance of the
related Series of Securities in an amount (the "Pre-Funded Amount") specified in
such Prospectus Supplement into an account (the "Pre-Funding Account"). In no
event shall the Pre-Funded Amount exceed 25% of the initial aggregate principal
amount of the Certificates and/or Notes of the related Series of Securities. The
Pre-Funded Amount will be used to purchase Loans ("Subsequent Loans") in a
period from the related Closing Date to a date not more than three months after
such Closing Date (such period, the "Funding Period") from the Depositor (which,
in turn, will acquire such Subsequent Loans from the Seller or Sellers specified
in the related Prospectus Supplement). The Pre-Funding Account will be
maintained with the Trustee for the related Series of Securities and is designed
solely to hold funds to be applied by such Trustee during the Funding Period to
pay to the Depositor the purchase price for Subsequent Loans. Monies on deposit
in the Pre-Funding Account will not be available to cover losses on or in
respect of the related Loans. To the extent that the entire Pre-Funded Amount
has not been applied to the purchase of Subsequent Loans by the end of the
related Funding Period, any amounts remaining in the Pre-Funding Account will be
distributed as a prepayment of principal to Certificateholders and/or
Noteholders on the Distribution Date immediately following the end of the
Funding Period, in the amounts and pursuant to the priorities set forth in the
related Prospectus Supplement. Any reinvestment risk resulting from such
prepayment will be borne entirely by the holders of one or more classes of the
related Series of Certificates.
 
BANKRUPTCY AND INSOLVENCY RISKS
 
     Insolvency of Depositor May Cause Losses and Delays.  The Seller and the
Depositor will treat the transfer of the Loans by the Seller to the Depositor as
a sale for accounting purposes. The Depositor and the Trust Fund will treat the
transfer of Loans from the Depositor to the Trust Fund as a sale for accounting
purposes. As a sale of the Loans by the Seller to the Depositor, the Loans would
not be part of the Seller's bankruptcy estate and would not be available to the
Seller's creditors. However, in the event of the insolvency of the Depositor, it
is possible that the bankruptcy trustee or a creditor of the Depositor may
attempt to recharacterize the sale of the Loans by the Depositor to the Trust
Fund as a borrowing by the Depositor, secured by a pledge of the Loans. In such
a case, this position, if argued before or accepted by a court, could prevent
timely payments of amounts due on the Securities and result in a reduction of
payments due on the Securities. If the sale of the Loans by the Depositor to the
Trust Fund is recharacterized as a borrowing by the
 
                                       25
<PAGE>   27
 
Depositor, the Loans will be part of the Depositor's bankruptcy estate and may
be available to repay other creditors of the Depositor as well as the Trust
Fund. Depending on the priority of the Trustee's security interest in the Loans,
the successful recharacterization of such sale as a borrowing may result in an
insufficient amount remaining to pay the Trust Fund after the claims of other
secured creditors of the Depositor have been reimbursed from any cash flow
relating to the Loans or proceeds from the disposition of the Loans and/or other
creditors have shared in the distribution of such cash flow or proceeds. Even if
the sale of the Loans is not so recharacterized, any litigation due to the
bankruptcy of the Depositor could result in a delay in payments from the cash
flow of the Loans to the Trustee.
 
     Insolvency of Master Servicer May Prevent Replacing Master Servicer.  In
the event of a bankruptcy or insolvency of the Master Servicer, the bankruptcy
trustee or receiver may have the power to prevent the Trustee or the
Securityholders from appointing a successor Master Servicer.
 
     Each Agreement will specify the time period during which cash collections
may be commingled with the Master Servicer's own funds prior to each
Distribution Date and such time period will also be specified in the related
Prospectus Supplement. In the event of the insolvency of the Master Servicer and
if such cash collections are commingled with the Master Servicer's own funds for
at least ten days, the Trust Fund will likely not have a perfected interest in
such collections since such collections would not have been deposited in a
segregated account within ten days after the collection thereof, and the
inclusion thereof in the bankruptcy estate of the Master Servicer may result in
delays in payment and failure to pay amounts due on the Securities of the
related Series.
 
     Insolvency of Loan Debtor May Cause Losses and Delays.  In addition,
federal and state statutory provisions, including the federal bankruptcy laws
and state laws affording relief to debtors, may interfere with or affect the
ability of the secured mortgage lender to realize upon its security. For
example, in a proceeding under the federal Bankruptcy Code, a lender may not
foreclose on a mortgaged property without the permission of the bankruptcy
court. The rehabilitation plan proposed by the debtor may provide, if the
mortgaged property is not the debtor's principal residence and the court
determines that the value of the mortgaged property is less than the principal
balance for the mortgage loan, for the reduction of the secured indebtedness to
the value of the mortgaged property as of the date of the commencement of the
bankruptcy, rendering the lender a general unsecured creditor for the
difference, and also may reduce the monthly payments due under such mortgage
loan, change the rate of interest and alter the mortgage loan repayment
schedule. The effect of any such proceedings under the federal Bankruptcy Code,
including but not limited to any automatic stay, could result in delays in
receiving payments on the Loans underlying a Series of Securities and possible
reductions in the aggregate amount of such payments.
 
TAX CONSEQUENCES OF OWNING ORIGINAL ISSUE DISCOUNT SECURITIES
 
     Debt Securities that are Compound Interest Securities will be, and certain
of the other Debt Securities may be, issued with original discount for federal
income tax purposes. A holder of Debt Securities issued with original issue
discount will be required to include original issue discount in ordinary gross
income for federal income tax purposes as it accrues, in advance of receipt of
the cash attributable to such income. Accrued but unpaid interest on the Debt
Securities that are Compound Interest Securities generally will be treated as
original issue discount for this purpose. See "Federal Income Tax
Consequences -- General -- Interest and Acquisition Discount" and "-- Market
Discount" herein.
 
VALUE OF TRUST FUND ASSETS MAY BE INSUFFICIENT
 
     There is no assurance that the market value of the Trust Fund Assets or any
other assets relating to a Series of Securities described under "Credit
Enhancement" herein will at any time be equal to or greater than the principal
amount of the Securities of such Series then outstanding, plus accrued interest
thereon. Moreover, upon an event of default under the Agreement for a Series of
Securities and a sale of the related Trust Fund Assets or upon a sale of the
assets of a Trust Fund for a Series of Securities, the Trustee, the Master
Servicer, the credit enhancer, if any, and any other service provider specified
in the related Prospectus Supplement generally will be entitled to receive the
proceeds of any such sale to the extent of unpaid fees and other amounts owing
to such persons under the related Agreement prior to distributions to
Securityholders.
 
                                       26
<PAGE>   28
 
Upon any such sale, the proceeds thereof may be insufficient to pay in full the
principal of and interest on the Securities of such Series.
 
VALUE OF INDEXED SECURITIES MAY BE AFFECTED
 
     An investment in Securities indexed, as to principal, premium and/or
interest, to one or more values of currencies (including exchange rates and swap
indices between currencies), commodities, interest rates or other indices
entails significant risks that are not associated with similar investments in a
conventional fixed-rate debt security. If the interest rate of such a Security
is so indexed, it may result in an interest rate that is less than that payable
on a conventional fixed-rate debt security issued at the same time, including
the possibility that no interest will be paid, and, if the principal amount of
such a Security is so indexed, the principal amount payable) on the related
final Distribution Date may be less than the original purchase price of such
Security if allowed pursuant to the terms of such Security, including the
possibility that no principal will be paid. The secondary market for such
Securities will be affected by a number of factors, independent of the
characteristics of the Trust Fund Assets, structure of the cash flows and the
value of the applicable currency commodity, interest rate or other index,
including the volatility of the applicable currency, commodity, interest rate or
other index, the time remaining to the maturity of such Securities, the amount
outstanding of such Securities and market interest rates. The value of the
applicable currency, commodity, interest rate or other index depends on a number
of interrelated factors, including economic, financial and political events.
Additionally, if the formula used to determine the principal amount, premium, if
any, or interest payable with respect to such Securities contains a multiple or
leverage factor, the effect of any change in the applicable currency, commodity,
interest rate or other index may be increased. The historical experience of the
relevant currencies, commodities, interest rates or other indices should not be
taken as an indication of future performance of such currencies, commodities,
interest rates or other indices during the term of any Security. The credit
ratings assigned to any Series or class of Securities, in no way, are reflective
of the potential impact of the factors discussed above, or any other factors, on
the market value of the Securities. Accordingly, prospective investors should
consult their own financial and legal advisors as to the risks entailed by an
investment in such Securities and the suitability of such Securities in light of
their particular circumstances.
 
                                 THE TRUST FUND
 
GENERAL
 
     The Securities of each Series will represent interests in the assets of the
related Trust Fund, and the Notes of each Series will be secured by the pledge
of the assets of the related Trust Fund. The Trust Fund for each Series will be
held by the Trustee for the benefit of the related Securityholders. Each Trust
Fund will consist of assets (the "Trust Fund Assets") consisting of a pool
(each, a "Pool") comprised of Loans, Agency Securities and/or Private
Mortgage-Backed Securities as specified in the related Prospectus Supplement,
together with payments in respect of such Loans, and certain other accounts,
obligations or agreements, in each case, as specified in the related Prospectus
Supplement.* The Pool will be created on the first day of the month of the
issuance of the related Series of Securities or such other date specified in the
related Prospectus Supplement (the "Cut-off Date"). The Securities will be
entitled to payment from the assets of the related Trust Fund or Funds or other
assets pledged for the benefit of the Securityholders, as specified in the
related Prospectus Supplement, and will not be entitled to payments in respect
of the assets of any other trust fund established by the Depositor.
 
- ---------------
 
*Whenever the terms "Pool," "Certificates," "Notes" and "Securities" are used in
 this Prospectus, such terms will be deemed to apply, unless the context
 indicates otherwise, to one specific Pool and the Securities of one Series
 including the Certificates representing certain undivided interests in, and/or
 Notes secured by the assets of, a single Trust Fund consisting primarily of the
 Loans, Agency Securities or Private Mortgage-Backed Securities in such Pool.
 Similarly, the term "Pass-Through Rate" will refer to the Pass-Through Rate
 borne by the Certificates and the term "interest rate" will refer to the
 interest rate borne by the Notes of one specific Series, as applicable, and the
 term "Trust Fund" will refer to one specific Trust Fund.
 
                                       27
<PAGE>   29
 
     The Trust Fund Assets will be acquired by the Depositor, either directly or
through affiliates, from sellers (the "Sellers"). The Sellers may be affiliates
of the Depositor. Loans acquired by the Depositor will have been originated in
accordance with the underwriting criteria described below under "The
Loans -- Underwriting Standards." The Depositor will cause the Trust Fund Assets
to be assigned without recourse to the Trustee named in the related Prospectus
Supplement for the benefit of the holders of the Securities of the related
Series. The Master Servicer named in the related Prospectus Supplement will
service the Trust Fund Assets, either directly or through other servicing
institutions ("Sub-Servicers"), pursuant to a Pooling and Servicing Agreement
among the Depositor, the Master Servicer and the Trustee with respect to a
Series consisting of Certificates, or a master servicing agreement (each, a
"Master Servicing Agreement") between the Trustee and the Master Servicer with
respect to a Series consisting of Certificates and Notes, and will receive a fee
for such services. See "The Agreements." With respect to Loans serviced by the
Master Servicer through a Sub-Servicer, the Master Servicer will remain liable
for its servicing obligations under the related Agreement as if the Master
Servicer alone were servicing such Loans.
 
     As used herein, "Agreement" means, with respect to a Series consisting of
Certificates, the Pooling and Servicing Agreement, and with respect to a Series
consisting of Certificates and Notes, the Trust Agreement, the Indenture and the
Master Servicing Agreement, as the context requires.
 
     If so specified in the related Prospectus Supplement, a Trust Fund relating
to a Series of Securities may be a business trust formed under the laws of the
state specified in the related Prospectus Supplement pursuant to a trust
agreement (each, a "Trust Agreement") between the Depositor and the trustee of
such Trust Fund.
 
     With respect to each Trust Fund, prior to the initial offering of the
related Series of Securities, the Trust Fund will have no assets or liabilities.
No Trust Fund is expected to engage in any activities other than acquiring,
managing and holding of the related Trust Fund Assets and other assets
contemplated herein specified and in the related Prospectus Supplement and the
proceeds thereof, issuing Securities and making payments and distributions
thereon and certain related activities. No Trust Fund is expected to have any
source of capital other than its assets and any related credit enhancement.
 
     Unless otherwise specified in the related Prospectus Supplement, the only
obligations of the Depositor with respect to a Series of Securities will be to
obtain certain representations and warranties from the Sellers or the
Originators and to assign to the Trustee for such Series the Depositor's rights
with respect to such representations and warranties. See "The
Agreements -- Assignment of the Trust Fund Assets." The obligations of the
Master Servicer with respect to the Loans will consist principally of its
contractual servicing obligations under the related Agreement (including its
obligation to enforce the obligations of the Sub-Servicers or Sellers, or both,
as more fully described herein under "The Trust Fund -- Representations by
Sellers or Originators; Repurchases" and "The Agreements -- Sub-Servicing By
Sellers" and "-- Assignment of the Trust Fund Assets") and its obligation, if
any, to make certain cash advances in the event of delinquencies in payments on
or with respect to the Loans in the amounts described herein under "Description
of the Securities -- Advances." The obligations of the Master Servicer to make
advances may be subject to limitations, to the extent provided herein and in the
related Prospectus Supplement.
 
     The following is a brief description of the assets expected to be included
in the Trust Funds. If specific information respecting the Trust Fund Assets is
not known at the time the related Series of Securities initially is offered,
more general information of the nature described below will be provided in the
related Prospectus Supplement, and specific information will be set forth in a
report on Form 8-K to be filed with the Securities and Exchange Commission
within fifteen days after the initial issuance of such Securities (the "Detailed
Description"). A copy of the Agreement with respect to each Series of Securities
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 Loans, Agency Securities and/or Private
Mortgage-Backed Securities relating to such Series will be attached to the
Agreement delivered to the Trustee upon delivery of the Securities.

THE LOANS
 
     General.  Unless otherwise specified in the related Prospectus Supplement,
Loans will consist of mortgage loans or deeds of trust secured by first or
subordinated liens on one- to four-family residential properties, Home Equity
Loans, Home Improvement Contracts or Manufactured Housing Contracts. For
purposes hereof, "Home Equity Loans" includes "Closed-End Loans" and "Revolving
Credit Line Loans." If so specified, the Loans may include cooperative apartment
loans ("Cooperative Loans") secured by security interests in shares issued by
private, non-profit, cooperative housing corporations ("Cooperatives") and in
the related proprietary leases or occupancy agreements granting exclusive rights
to occupy specific dwelling units in such Cooperatives' buildings. As more fully
described in the related Prospectus Supplement, the Loans may be "conventional"
loans or loans that are insured or guaranteed by a governmental agency such as
the FHA or VA. The Loans will have been originated in accordance with the
underwriting criteria specified in the related Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, all of the
Loans in a Pool will have monthly payments due on the first day of each month.
The payment terms of the Loans to be included in a Trust Fund will be described
in the related Prospectus Supplement and may include any of the following
features (or combination thereof), all as described below or in the related
Prospectus Supplement:
 
          (a) Interest may be payable at a fixed rate, a rate adjustable from
     time to time in relation to an index (which will be specified in the
     related Prospectus Supplement), a rate that is fixed for a period of time
     or under certain circumstances and is followed by an adjustable rate, a
     rate that otherwise varies from time to time, or a rate that is convertible
     from an adjustable rate to a fixed rate. Changes to an adjustable rate may
     be subject to periodic limitations, maximum rates, minimum rates or a
     combination of such limitations. As specified in the related Prospectus
     Supplement, the Loans will provide either for payments in level monthly
     installments (except in the case of Loans with balloon payments) consisting
     of interest equal to one-twelfth of the specified interest rate borne by
     such Loan (the "Loan Rate") times the unpaid principal balance, with the
     remainder of such payment applied to principal, for payments that are
     allocated to principal and interest according to the daily simple interest
     method, or for payments that are allocated to principal and interest
     according to the "sum of the digits" or "Rule of 78s" methods. Accrued
     interest may be deferred and added to the principal of a Loan for such
     periods and under such circumstances as may be specified in the related
     Prospectus Supplement. Loans may provide for the payment of interest at a
     rate lower than the Loan Rate for a period of time or for the life of the
     Loan, and the amount of any difference may be contributed from funds
     supplied by the seller of the Property or another source.
 
          (b) Principal may be payable on a level debt service basis to fully
     amortize the Loan over its term, may be calculated on the basis of an
     assumed amortization schedule that is significantly longer than the
     original term to maturity or on an interest rate that is different from the
     Loan Rate or may not be amortized during all or a portion of the original
     term. Payment of all or a substantial portion of the principal may be due
     on maturity ("balloon payment"). Principal may include interest that has
     been deferred and added to the principal balance of the Loan.
 
          (c) Monthly payments of principal and interest may be fixed for the
     life of the Loan, may increase over a specified period of time or may
     change from period to period. Loans may include limits on periodic
     increases or decreases in the amount of monthly payments and may include
     maximum or minimum amounts of monthly payments.
 
          (d) Prepayments of principal may be subject to a prepayment fee, which
     may be fixed for the life of the Loan or may decline over time, and may be
     prohibited for the life of the Loan or for certain periods ("lockout
     periods"). Certain Loans may permit prepayments after expiration of the
     applicable lockout period and may require the payment of a prepayment fee
     in connection with any such subsequent prepayment. Other Loans may permit
     prepayments without payment of a fee unless the prepayment occurs during
     specified time periods. The Loans may include "due on sale" clauses which
     permit the mortgagee to demand payment of the entire Loan in connection
     with the sale or certain transfers of the
 
                                       29
<PAGE>   31
 
     related Property. Other Loans may be assumable by persons meeting the then
     applicable underwriting standards of the related Seller.
 
     A Trust Fund may contain certain Loans ("Buydown Loans") that include
provisions whereby a third party partially subsidizes the monthly payments of
the borrowers on such Loans during the early years of such Loans, the difference
to be made up from a fund (a "Buydown Fund") contributed by such third party at
the time of origination of the Loan. A Buydown Fund will be in an amount equal
either to the discounted value or full aggregate amount of future payment
subsidies. The underlying assumption of buydown plans is that the income of the
borrower will increase during the buydown period as a result of normal increases
in compensation and inflation, so that the borrower will be able to meet the
full loan payments at the end of the buydown period. To the extent that this
assumption as to increased income is not fulfilled, the possibility of defaults
on Buydown Loans is increased. The related Prospectus Supplement will contain
information with respect to any Buydown Loan concerning limitations on the
interest rate paid by the borrower initially, on annual increases in the
interest rate and on the length of the buydown period.
 
     The real property which secures repayment of the Loans is referred to as
the "Mortgaged Properties." Home Improvement Contracts and Manufactured Housing
Contracts may, and the other Loans will, be secured by mortgages or deeds of
trust or other similar security instruments creating a lien on a Mortgaged
Property. In the case of Home Equity Loans, such liens generally will be
subordinated to one or more senior liens on the related Mortgaged Properties as
described in the related Prospectus Supplement. As specified in the related
Prospectus Supplement, Home Improvement Contracts and Manufactured Housing
Contracts may be unsecured or secured by purchase money security interests in
the Home Improvements and Manufactured Homes financed thereby. The Mortgaged
Properties, and the Home Improvements and the Manufactured Homes are
collectively referred to herein as the "Properties." The Properties relating to
Loans will consist primarily of detached or semi-detached one- to four-family
dwelling units, townhouses, rowhouses, individual condominium units, individual
units in planned unit developments, and certain other dwelling units ("Single
Family Properties") or "mixed used properties" which consist of structures of
not more than three stories which include one- to four-family residential
dwelling units and space used for retail, professional or other commercial uses.
Such Properties may include vacation and second homes, investment properties and
leasehold interests. In the case of leasehold interests, the term of the
leasehold will exceed the scheduled maturity of the Loan by at least five years,
unless otherwise specified in the related Prospectus Supplement. The Properties
may be located in any one of the fifty states, the District of Columbia, Guam,
Puerto Rico or any other territory of the United States.
 
     Loans with certain Loan-to-Value Ratios and/or certain principal balances
may be covered wholly or partially by primary mortgage guaranty insurance
policies (each, a "Primary Mortgage Insurance Policy"). The existence, extent
and duration of any such coverage will be described in the applicable Prospectus
Supplement.
 
     The aggregate principal balance of Loans secured by Properties that are
owner-occupied will be disclosed in the related Prospectus Supplement. Unless
otherwise specified in the related Prospectus Supplement, the sole basis for a
representation that a given percentage of the Loans is secured by Single Family
Properties that are owner-occupied will be either (i) the making of a
representation by the borrower at origination of the Loan either that the
underlying Property will be used by the borrower for a period of at least six
months every year or that the borrower intends to use the Property as a primary
residence or (ii) a finding that the address of the underlying Property is the
borrower's mailing address.
 
     Home Equity Loans.  As more fully described in the related Prospectus
Supplement, interest on each Revolving Credit Line Loan, excluding introduction
rates offered from time to time during promotional periods, is computed and
payable monthly on the average daily outstanding principal balance of such Loan.
Principal amounts on a Revolving Credit Line Loan may be drawn down (up to a
maximum amount as set forth in the related Prospectus Supplement) or repaid
under each Revolving Credit Line Loan from time to time, but may be subject to a
minimum periodic payment. Except to the extent provided in the related
Prospectus Supplement, the Trust Fund will not include any amounts borrowed
under a Revolving Credit Line Loan after the Cut-off Date. The full amount of a
Closed-End Loan is advanced at the inception of the Loan
 
                                       30
<PAGE>   32
 
and generally is repayable in equal (or substantially equal) installments of an
amount to fully amortize such Loan at its stated maturity. Except to the extent
provided in the related Prospectus Supplement, the original terms to stated
maturity of Closed-End Loans will not exceed 360 months. Under certain
circumstances, under either a Revolving Credit Line Loan or a Closed-End Loan, a
borrower may choose an interest only payment option and is obligated to pay only
the amount of interest which accrues on the Loan during the billing cycle. An
interest only payment option may be available for a specified period before the
borrower must begin paying at least the minimum monthly payment of a specified
percentage of the average outstanding balance of the Loan.
 
     Home Improvement Contracts.  The Trust Fund Assets for a Series of
Securities may consist, in whole or in part, of Home Improvement Contracts
originated by a commercial bank, a savings and loan association, a commercial
mortgage banker or other financial institution in the ordinary course of
business. The Home Improvements securing the Home Improvement Contracts may
include, but are not limited to, replacement windows, house siding, new roofs,
swimming pools, satellite dishes, kitchen and bathroom remodeling goods and
solar heating panels. As specified in the related Prospectus Supplement, the
Home Improvement Contracts will either be unsecured or secured by mortgages on
Single Family Properties which are generally subordinate to other mortgages on
the same Property, or secured by purchase money security interests in the Home
Improvements financed thereby. Except as otherwise specified in the related
Prospectus Supplement, the Home Improvement Contracts will be fully amortizing
and may have fixed interest rates or adjustable interest rates and may provide
for other payment characteristics as described below and in the related
Prospectus Supplement. The initial Loan-to-Value Ratio of a Home Improvement
Contract is computed in the manner described in the related Prospectus
Supplement.
 
     Manufactured Housing Contracts.  The Trust Fund Assets for a Series may
consist, in whole or part, of conventional manufactured housing installment
sales contracts and installment loan agreements (the "Manufactured Housing
Contracts" and together with the Home Improvement Contracts, the "Contracts"),
originated by a manufactured housing dealer in the ordinary course of business.
As specified in the related Prospectus Supplement, the Manufactured Housing
Contracts will be secured by either Manufactured Homes (as defined below),
located in any of the fifty states or the District of Columbia or by Mortgages
on the real estate on which the Manufactured Homes are located.
 
     Unless otherwise specified in the related Prospectus Supplement, the
manufactured homes (the "Manufactured Homes") securing the Manufactured Housing
Contracts will 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 and 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."
 
     Manufactured Homes, unlike Mortgaged Properties, and Home Improvements,
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 or Home Improvement
may be lower than the principal amount outstanding under the related Contract.
 
     Additional Information.  Each Prospectus Supplement will contain
information, as of the date of such Prospectus Supplement and to the extent then
specifically known to the Depositor, with respect to the Loans contained in the
related Pool, including (i) the aggregate outstanding principal balance and the
average outstanding principal balance of the Loans as of the applicable Cut-off
Date, (ii) the type of property securing the Loan (e.g., single family
residences, individual units in condominium apartment buildings, two- to four-
family dwelling units, other real property, Home Improvements or Manufactured
Homes), (iii) the original terms to maturity of the Loans, (iv) the largest
principal balance and the smallest principal balance of any of
 
                                       31
<PAGE>   33
 
the Loans, (v) the earliest origination date and latest maturity date of any of
the Loans, (vi) the Loan-to-Value Ratios or Combined Loan-to-Value Ratios, as
applicable, of the Loans, (vii) the Loan Rates or annual percentage rates
("APR") or range of Loan Rates or APR's borne by the Loans, (viii) the maximum
and minimum per annum Loan Rates, and (ix) the geographical location of the
Loans. If specific information respecting the Loans is not known to the
Depositor at the time the related Securities are initially offered, more general
information of the nature described above will be provided in the related
Prospectus Supplement, and specific information will be set forth in the
Detailed Description.
 
     The "Loan-to-Value Ratio" of a Loan at any given time is the fraction,
expressed as a percentage, the numerator of which is the original principal
balance of the related Loan and the denominator of which is the Collateral Value
of the related Property. Except as otherwise specified in the related Prospectus
Supplement, the "Combined Loan-to-Value Ratio" of a Loan at any given time is
the ratio, expressed as a percentage, of (i) the sum of (a) the original
principal balance of the Loan (or, in the case of a Revolving Credit Line Loan,
the maximum amount thereof available) and (b) the outstanding principal balance
at the date of origination of the Loan of any senior mortgage loan(s) or, in the
case of any open-ended senior mortgage loan, the maximum available line of
credit with respect to such mortgage loan, regardless of any lesser amount
actually outstanding at the date of origination of the Loan, to (ii) the
Collateral Value of the related Property. Except as otherwise specified in the
related Prospectus Supplement, the "Collateral Value" of the Property, other
than with respect to certain Loans the proceeds of which were used to refinance
an existing mortgage loan (each, a "Refinance Loan"), is the lesser of (a) the
appraised value determined in an appraisal obtained by the originator at
origination of such Loan and (b) the sales price for such Property. In the case
of Refinance Loans, the "Collateral Value" of the related Property is the
appraised value thereof determined in an appraisal obtained at the time of
refinancing.
 
     No assurance can be given that values of the Properties have remained or
will remain at their levels on the dates of origination of the related Loans. If
the residential real estate market should experience an overall decline in
property values such that the sum of the outstanding principal balances of the
Loans and any primary or secondary financing on the Properties, as applicable,
in a particular Pool become equal to or greater than the value of the
Properties, the actual rates of delinquencies, foreclosures and losses could be
higher than those now generally experienced in the mortgage lending industry. In
addition, adverse economic conditions and other factors (which may or may not
affect real property values) may affect the timely payment by borrowers of
scheduled payments of principal and interest on the Loans and, accordingly, the
actual rates of delinquencies, foreclosures and losses with respect to any Pool.
To the extent that such losses are not covered by subordination provisions or
alternative arrangements, such losses will be borne, at least in part, by the
holders of the Securities of the related Series.
 
     Underwriting Standards.  The Loans will be acquired by the Depositor,
either directly or through affiliates, from the Sellers. The Depositor does not
originate Loans and has not identified specific Originators or Sellers of Loans
from whom the Depositor, either directly or through affiliates, will purchase
Loans. Unless otherwise specified in the related Prospectus Supplement, the
Loans will be originated in accordance with the following underwriting criteria.
Each Seller or Originator will represent and warrant that all Loans originated
and/or sold by it to the Depositor or one of its affiliates will have been
underwritten in accordance with standards consistent with those utilized by
lenders generally during the period of origination for similar types of loans.
As to any Loan insured by the FHA or partially guaranteed by the VA, the Seller
or Originator will represent that it has complied with underwriting policies of
the FHA or the VA, as the case may be.
 
     Underwriting standards are applied by or on behalf of a lender to evaluate
the borrower's credit standing and repayment ability, and the value and adequacy
of the related Mortgaged Property, Home Improvements or Manufactured Home, as
applicable, as collateral. In general, a prospective borrower applying for a
Loan is required to fill out a detailed application designed to provide to the
underwriting officer pertinent credit information, including, among other
things, the principal balance and payment history with respect to any senior
mortgage, if any, which, unless otherwise specified in the related Prospectus
Supplement, will be verified by the related Seller or Originator. As part of the
description of the borrower's financial condition, the borrower generally is
required to provide a current list of assets and liabilities and a statement of
income and expenses, as well as an authorization to apply for a credit report
which summarizes the borrower's credit
 
                                       32
<PAGE>   34
 
history with local merchants and lenders and any record of bankruptcy. In most
cases, an employment verification is obtained from an independent source
(typically the borrower's employer) which verification reports, among other
things, the length of employment with that organization and the borrower's
current salary. If a prospective borrower is self-employed, the borrower may be
required to submit copies of signed tax returns. The borrower may also be
required to authorize verification of deposits at financial institutions where
the borrower has demand or savings accounts.
 
     In determining the adequacy of the property to be used as collateral, an
appraisal, if applicable, will generally be made of each property considered for
financing. The appraiser is generally required to inspect the property, issue a
report on its condition and, if applicable, verify construction, if new, has
been completed. The appraisal is based on the market value of comparable
properties, the estimated rental income (if considered applicable by the
appraiser) and the cost of replacing the collateral. The value of the property
being financed, as indicated by the appraisal, must be such that it currently
supports, and is anticipated to support in the future, the outstanding loan
balance.
 
     The maximum loan amount will vary depending upon a borrower's credit grade
and loan program but will not generally exceed an amount specified in the
related Prospectus Supplement. Variations in maximum loan amount limits will be
permitted based on compensating factors. Compensating factors may generally
include, to the extent specified in the related Prospectus Supplement, low
loan-to-value ratio, low debt-to-income ratio, stable employment, favorable
credit history and the nature of the underlying first mortgage loan, if
applicable.
 
     Each Seller's or Originator's underwriting standards will generally permit
loans with loan-to-value ratios at origination of up to 100% depending on the
loan program, type and use of the property, creditworthiness of the borrower and
debt-to-income ratio.
 
     After obtaining all applicable employment, credit and property information,
the related Seller or Originator will use a debt-to-income ratio to assist in
determining whether the prospective borrower has sufficient monthly income
available to support the payments of principal and interest on the loan in
addition to other monthly credit obligations. The "debt-to-income ratio" is the
ratio of the borrower's total monthly payments to the borrower's gross monthly
income. The maximum monthly debt-to-income ratio will vary depending upon a
borrower's credit grade and loan program but will not generally exceed an amount
specified in the related Prospectus Supplement. Variations in the monthly
debt-to-income ratio limit will be permitted based on compensating factors to
the extent specified in the related Prospectus Supplement.
 
     Certain of the types of Loans that may be included in a Trust Fund are
recently developed and may involve additional uncertainties not present in
traditional types of loans. For example, certain of such Loans are underwritten
on the basis of a judgment that the borrowers have the ability to make the
monthly payments required initially. In some instances, a borrower's income may
not be sufficient to permit continued loan payments as such payments increase.
These types of Loans may also be underwritten primarily upon the basis of
loan-to-value ratios or other favorable credit factors.
 
MODIFICATION OF LOANS
 
     The Master Servicer may agree, subject to the terms and conditions set
forth in the related Agreement, to modify, waive or amend any term of a Loan in
a manner that is consistent with the servicing standard set forth in the related
Agreement and related Prospectus Supplement; provided however, that such
modification, waiver or amendment may not affect the tax status of the Trust
Fund or cause any tax to be imposed on the Trust Fund or materially impair the
security for the related Loan.
 
AGENCY SECURITIES
 
     Government National Mortgage Association.  GNMA is a wholly-owned corporate
instrumentality of the United States within the United Stated Department of
Housing and Urban Development ("HUD"). Section 306(g) of Title II of the
National Housing Act of 1934, as amended (the "Housing Act"), authorizes GNMA
to, among other things, guarantee the timely payment of the principal of and
interest on certificates which represent an interest in a pool of mortgage loans
insured by the FHA under the Housing Act or Title V
 
                                       33

of the Housing Act of 1949 ("FHA Loans"), or partially guaranteed by the VA
under the Servicemen's Readjustment Act of 1944, as amended, or chapter 37 of
Title 38, United States Code ("VA Loans").
 
     Section 306(g) of the Housing Act provides that "the full faith and credit
of the United States is pledged to the payment of all amounts which may be
required to be paid under any guarantee under this subsection." In order to meet
its obligations under any such guarantee, GNMA may, under Section 306(d) of the
Housing Act, borrow from the United States Treasury in an amount which is at any
time sufficient to enable GNMA, with no limitations as to amount, to perform its
obligations under its guarantee.
 
     GNMA Certificates.  Each GNMA Certificate held in a Trust Fund (which may
be a GNMA I Certificate or a GNMA II Certificate) will be a "fully modified
pass-through" mortgaged-backed certificate issued and serviced by a mortgage
banking company or other financial concern ("GNMA Issuer") approved by GNMA or
approved by FNMA as a seller-servicer of FHA Loans and/or VA Loans. The mortgage
loans underlying the GNMA Certificates held in a Trust Fund will consist of FHA
Loans and/or VA Loans. Each such mortgage loan is secured by a one- to
four-family residential property or a manufactured home. GNMA will approve the
issuance of each such GNMA Certificate in accordance with a guaranty agreement
(a "Guaranty Agreement") between GNMA and the GNMA Issuer. Pursuant to its
Guaranty Agreement, a GNMA Issuer will be required to advance its own funds in
order to make timely payments of all amounts due on each such GNMA Certificate,
even if the payments received by the GNMA Issuer on the FHA Loans or VA Loans
underlying each such GNMA Certificate are less than the amounts due on each such
GNMA Certificate.
 
     The full and timely payment of principal of and interest on each GNMA
Certificate will be guaranteed by GNMA, which obligation is backed by the full
faith and credit of the United States. Each such GNMA Certificate will have an
original maturity of not more than 40 years (but may have original maturities of
substantially less than 40 years). Each such GNMA Certificate will provide for
the payment by or on behalf of the GNMA Issuer to the registered holder of such
GNMA Certificate of scheduled monthly payments of principal and interest equal
to the registered holder's proportionate interest in the aggregate amount of the
monthly principal and interest payment on each FHA Loan or VA Loan underlying
such GNMA Certificate, less the applicable servicing and guarantee fee which
together equal the difference between the interest on the FHA Loans or VA Loans
and the pass-through rate on the GNMA Certificate. In addition, each payment
will include proportionate pass-through payments of any prepayments of principal
on the FHA Loans or VA Loans underlying such GNMA Certificate and liquidation
proceeds in the event of a foreclosure or other disposition of any such FHA
Loans or VA Loans.
 
     If a GNMA Issuer is unable to make the payments on a GNMA Certificate as it
becomes due, it must promptly notify GNMA and request GNMA to make such payment.
Upon notification and request, GNMA will make such payments directly to the
registered holder of such GNMA Certificate. In the event no payment is made by a
GNMA Issuer and the GNMA Issuer fails to notify and request GNMA to make such
payment, the holder of such GNMA Certificate will have recourse only against
GNMA to obtain such payment. The Trustee or its nominee, as registered holder of
the GNMA Certificates held in a Trust Fund, will have the right to proceed
directly against GNMA under the terms of the Guaranty Agreements relating to
such GNMA Certificates for any amounts that are not paid when due.
 
     All mortgage loans underlying a particular GNMA Certificate must have the
same interest rate (except for pools of mortgage loans secured by manufactured
homes) over the term of the loan. The interest rate on such GNMA I Certificate
will equal the interest rate on the mortgage loans included in the pool of
mortgage loans underlying such GNMA I Certificate, less one-half percentage
point per annum of the unpaid principal balance of the mortgage loans.
 
     Mortgage loans underlying a particular GNMA II Certificate may have per
annum interest rates that vary from each other by up to one percentage point.
The interest rate on each GNMA II Certificate will be between one-half
percentage point and one and one-half percentage points lower than the highest
interest rate on the mortgage loans included in the pool of mortgage loans
underlying such GNMA II Certificate (except for pools of mortgage loans secured
by manufactured homes).
 
                                       34
<PAGE>   36
 
     Regular monthly installment payments on each GNMA Certificate held in a
Trust Fund will be comprised of interest due as specified on such GNMA
Certificate plus the scheduled principal payments on the FHA Loans or VA Loans
underlying such GNMA Certificate due on the first day of the month in which the
scheduled monthly installments on such GNMA Certificate is due. Such regular
monthly installments on each such GNMA Certificate are required to be paid to
the Trustee as registered holder by the 15th day of each month in the case of a
GNMA I Certificate and are required to be mailed to the Trustee by the 20th day
of each month in the case of a GNMA II Certificate. Any principal prepayments on
any FHA Loans or VA Loans underlying a GNMA Certificate held in a Trust Fund or
any other early recovery of principal on such loan will be passed through to the
Trustee as the registered holder of such GNMA Certificate.
 
     GNMA Certificates may be backed by graduated payment mortgage loans or by
"buydown" mortgage loans for which funds will have been provided (and deposited
into escrow accounts) for application to the payment of a portion of the
borrowers' monthly payments during the early years of such mortgage loan.
Payments due the registered holders of GNMA Certificates backed by pools
containing "buydown" mortgage loans will be computed in the same manner as
payments derived from other GNMA Certificates and will include amounts to be
collected from both the borrower and the related escrow account. The graduated
payment mortgage loans will provide for graduated interest payments that, during
the early years of such mortgage loans, will be less than the amount of stated
interest on such mortgage loans. The interest not so paid will be added to the
principal of such graduated payment mortgage loans and, together with interest
thereon, will be paid in subsequent years. The obligations of GNMA and of a GNMA
Issuer will be the same irrespective of whether the GNMA Certificates are backed
by graduated payment mortgage loans or "buydown" mortgage loans. No statistics
comparable to the FHA's prepayment experience on level payment, non-buydown
loans are available in respect of graduated payment or buydown mortgages. GNMA
Certificates related to a Series of Certificates may be held in book-entry form.
 
     GNMA also guarantees the timely payment of principal of and interest on
"fully modified pass-through" mortgage-backed securities issued and serviced by
certain mortgage banking companies and other financial concerns ("FNMA Project
Issuers") based upon and backed by pools of multi-family residential mortgage
loans coinsured by FHA and GNMA Project Issuers under the Housing Act ("GNMA
Project Certificates"). The Prospectus Supplement for a Series of Certificates
that includes GNMA Project Certificates will set forth additional information
regarding the GNMA guaranty program, servicing of the mortgage pool, the payment
of principal and interest on GNMA Project Certificates and other matters with
respect to multi-family residential mortgage loans that qualify for the GNMA
guaranty.
 
     Federal National Mortgage Association.  FNMA is a federally chartered and
privately owned corporation organized and existing under the Federal National
Mortgage Association Charter Act (the "Charter Act"). FNMA was originally
established in 1938 as a United States government agency to provide supplemental
liquidity to the mortgage market and was transformed into a stockholder-owned
and privately-managed corporation by legislation enacted in 1968.
 
     FNMA provides funds to the mortgage market primarily by purchasing mortgage
loans from lenders, thereby replenishing their funds for additional lending.
FNMA acquires funds to purchase mortgage loans from many capital market
investors that may not ordinarily invest in mortgages, thereby expanding the
total amount of funds available for housing. Operating nationwide, FNMA helps to
redistribute mortgage funds from capital-surplus to capital-short areas.
 
     FNMA Certificates.  FNMA Certificates are either Guaranteed Mortgage
Pass-Through Certificates ("FNMA MBS") or Stripped Mortgage-Backed Securities
("FNMA SMBS"). The following discussion of FNMA Certificates applies equally to
both FNMA MBS and FNMA SMBS, except as otherwise indicated. Each FNMA
Certificate included in the Trust Fund for a Series will represent a fractional
undivided interest in a pool of mortgage loans formed by FNMA. Each such pool
will consist of mortgage loans of one of the following types: (i) fixed-rate
level installment conventional mortgage loans; (ii) fixed-rate level installment
mortgage loans that are insured by FHA or partially guaranteed by the VA; (iii)
adjustable rate conventional mortgage loans; or (iv) adjustable rate mortgage
loans that are insured by the FHA or partially guaranteed by the VA. Each
mortgage loan must meet the applicable standards set forth under the FNMA
purchase
 
                                       35
<PAGE>   37
 
program. Each such mortgage loan will be secured by a first lien on a one- to
four-family residential property. Each such FNMA Certificate will be issued
pursuant to a trust indenture. Original maturities of substantially all of the
conventional, level payment mortgage loans underlying a FNMA Certificate are
expected to be between either 8 to 15 years or 20 to 40 years. The original
maturities of substantially all of the fixed rate level payment FHA Loans or VA
Loans are expected to be 30 years.
 
     Mortgage loans underlying a FNMA Certificate may have annual interest rates
that vary by as much as two percentage points from each other. The rate of
interest payable on a FNMA MBS (and the series pass-through rate payable with
respect to a FNMA SMBS) is equal to the lowest interest rate of any mortgage
loan in the related pool, less a specified minimum annual percentage
representing servicing compensation and FNMA's guaranty fee. Under a regular
servicing option (pursuant to which the mortgagee or other servicer assumes the
entire risk of foreclosure losses), the annual interest rates on the mortgage
loans underlying a FNMA Certificate will be between 50 basis points and 250
basis points greater than the annual pass-through rate if a FNMA MBS or the
series pass-through rate if a FNMA SMBS; and under a special servicing option
(pursuant to which FNMA assumes the entire risk for foreclosure losses), the
annual interest rates on the mortgage loans underlying a FNMA Certificate will
generally be between 55 basis points and 255 basis points greater than the
annual FNMA Certificate pass-through rate if a FNMA MBS, or the series
pass-through rate if a FNMA SMBS.
 
     FNMA guarantees to each registered holder of a FNMA Certificate that it
will distribute on a timely basis amounts representing such holder's
proportionate share of scheduled principal and interest payments at the
applicable pass-through rate provided for by such FNMA Certificate on the
underlying mortgage loans, whether or not received, and such holder's
proportionate share of the full principal amount of any foreclosed or other
finally liquidated mortgage loan, whether or not such principal amount is
actually recovered. The obligations of FNMA under its guarantees are obligations
solely of FNMA and are not backed by, nor entitled to, the full faith and credit
of the United States. If FNMA were unable to satisfy its obligations,
distributions to holders of FNMA Certificates would consist solely of payments
and other recoveries on the underlying mortgage loans and, accordingly, monthly
distributions to holders of FNMA Certificates would be affected by delinquent
payments and defaults on such mortgage loans.
 
     FNMA SMBS are issued in series of two or more classes, with each class
representing a specified undivided fractional interest in principal
distributions and interest distributions (adjusted to the series pass-through
rate) on the underlying pool of mortgage loans. The fractional interests of each
class in principal and interest distributions are not identical, but the classes
in the aggregate represent 100% of the principal distributions and interest
distributions (adjusted to the series pass-through rate) on the respective pool.
Because of such difference between the fractional interests in principal and
interest of each class, the effective rate of interest on the principal of each
class of FNMA SMBS may be significantly higher or lower than the series
pass-through rate and/or the weighted average interest rate of the underlying
mortgage loans.
 
     Unless otherwise specified by FNMA, FNMA Certificates evidencing interests
in pools of mortgages formed on or after May 1, 1985 will be available in
book-entry form only. Distributions of principal and interest on each FNMA
Certificate will be made by FNMA on the 25th day of each month to the persons in
whose name the FNMA Certificate is entered in the books of the Federal Reserve
Banks (or registered on the FNMA Certificate register in the case of fully
registered FNMA Certificates) as of the close of business on the last day of the
preceding month. With respect to FNMA Certificates issued in book-entry form,
distributions thereon will be made by wire, and with respect to fully registered
FNMA Certificates, distributions thereon will be made by check.
 
     Federal Home Loan Mortgage Corporation.  FHLMC is a publicly held United
States government-sponsored enterprise created pursuant to the Federal Home Loan
Mortgage Corporation Act, Title III of the Emergency Home Finance Act of 1970,
as amended (the "FHLMC Act"). The common stock of FHLMC is owned by the Federal
Home Loan Banks. FHLMC was established primarily for the purpose of increasing
the availability of mortgage credit for the financing of urgently needed
housing. It seeks to provide an enhanced degree of liquidity for residential
mortgage investments primarily by assisting in the development of secondary
markets for conventional mortgages. The principal activity of FHLMC currently
consists of the purchase of
 
                                       36
<PAGE>   38
 
first lien conventional mortgage loans FHA Loans, VA Loans or participation
interests in such mortgage loans and the sale of the loans or participations so
purchased in the form of mortgage securities, primarily FHLMC Certificates.
FHLMC is confined to purchasing, so far as practicable, mortgage loans that it
deems to be of such quality, type and class as to meet generally the purchase
standards imposed by private institutional mortgage investors.
 
     FHLMC Certificates.  Each FHLMC Certificate represents an undivided
interest in a pool of mortgage loans that may consist of first lien conventional
loans, FHA Loans or VA Loans (a "FHLMC Certificate Group"). FHLMC Certificates
are sold under the terms of a Mortgage Participation Certificate Agreement. A
FHLMC Certificate may be issued under either FHLMC's Cash Program or Guarantor
Program. Unless otherwise described in the Prospectus Supplement, mortgage loans
underlying the FHLMC Certificates held by a Trust Fund will consist of mortgage
loans with original terms to maturity of between 10 and 40 years. Each such
mortgage loan must meet the applicable standards set forth in the FHLMC Act. A
FHLMC Certificate Group may include whole loans, participation interests in
whole loans and undivided interests in whole loans and/or participations
comprising another FHLMC Certificate Group. Under the Guarantor Program, any
such FHLMC Certificate Group may include only whole loans or participation
interests in whole loans.
 
     FHLMC guarantees to each registered holder of a FHLMC Certificate the
timely payment of interest on the underlying mortgage loans to the extent of the
applicable Certificate rate on the registered holder's pro rata share of the
unpaid principal balance outstanding on the underlying mortgage loans in the
FHLMC Certificate Group represented by such FHLMC Certificate, whether or not
received. FHLMC also guarantees to each registered holder of a FHLMC Certificate
ultimate receipt by such holder of all principal on the underlying mortgage
loans, without any offset or deduction, to the extent of such holder's pro rata
share thereof, but does not, except if and to the extent specified in the
Prospectus Supplement for a Series of Certificates, guarantee the timely payment
of scheduled principal. Under FHLMC's Gold PC Program, FHLMC guarantees the
timely payment of principal based on the difference between the pool factor
published in the month preceding the month of distribution and the pool factor
published in such month of distribution. Pursuant to its guarantees, FHLMC
indemnifies holders of FHLMC Certificates against any diminution in principal by
reason of charges for property repairs, maintenance and foreclosure. FHLMC may
remit the amount due on account of its guarantee of collection of principal at
any time after default on an underlying mortgage loan, but not later than (i) 30
days following foreclosure sale, (ii) 30 days following payment of the claim by
any mortgage insurer, or (iii) 30 days following the expiration of any right of
redemption, whichever occurs later, but in any event no later than one year
after demand has been made upon the mortgagor for accelerated payment of
principal. In taking actions regarding the collection of principal after default
on the mortgage loans underlying FHLMC Certificates, including the timing of
demand for acceleration, FHLMC reserves the right to exercise its judgment with
respect to the mortgage loans in the same manner as for mortgage loans which it
has purchased but not sold. The length of time necessary for FHLMC to determine
that a mortgage loan should be accelerated varies with the particular
circumstances of each mortgagor, and FHLMC has not adopted standards which
require that the demand be made within any specified period.
 
     FHLMC Certificates are not guaranteed by the United States or by any
Federal Home Loan Bank and do not constitute debts or obligations of the United
States or any Federal Home Loan Bank. The obligations of FHLMC under its
guarantee are obligations solely of FHLMC and are not backed by, nor entitled
to, the full faith and credit of the United States. If FHLMC were unable to
satisfy such obligations, distributions to holders of FHLMC Certificates would
consist solely of payments and other recoveries on the underlying mortgage loans
and, accordingly, monthly distributions to holders of FHLMC Certificates would
be affected by delinquent payments and defaults on such mortgage loans.
 
     Registered holders of FHLMC Certificates are entitled to receive their
monthly pro rata share of all principal payments on the underlying mortgage
loans received by FHLMC, including any scheduled principal payments, full and
partial prepayments of principal and principal received by FHLMC by virtue of
condemnation, insurance, liquidation or foreclosure, and repurchases of the
mortgage loans by FHLMC or the seller thereof. FHLMC is required to remit each
registered FHLMC Certificateholder's pro rata share of principal payments on the
underlying mortgage loans, interest at the FHLMC pass-through rate and any other
 
                                       37
<PAGE>   39
 
sums such as prepayment fees, within 60 days of the date on which such payments
are deemed to have been received by FHLMC.
 
     Under FHLMC's Cash Program, with respect to pools formed prior to June 1,
1987, there is no limitation on the amount by which interest rates on the
mortgage loans underlying a FHLMC Certificate may exceed the pass-through rate
on the FHLMC Certificate. With respect to FHLMC Certificates issued on or after
June 1, 1987, the maximum interest rate on the mortgage loans underlying such
FHLMC Certificates may exceed the pass through rate of the FHLMC Certificates by
50 to 100 basis points. Under such program, FHLMC purchases groups of whole
mortgage loans from sellers at specified percentages of their unpaid principal
balances, adjusted for accrued or prepaid interest, which when applied to the
interest rate of the mortgage loans and participations purchased, results in the
yield (expressed as a percentage) required by FHLMC. The required yield, which
includes a minimum servicing fee retained by the servicer, is calculated using
the outstanding principal balance. The range of interest rates on the mortgage
loans and participations in a FHLMC Certificate group under the Cash Program
will vary since mortgage loans and participations are purchased and assigned to
a FHLMC Certificate group based upon their yield to FHLMC rather than on the
interest rate on the underlying mortgage loans.
 
     Under FHLMC's Guarantor Program, the pass-through rate on a FHLMC
Certificate is established based upon the lowest interest rate on the underlying
mortgage loans, minus a minimum servicing fee and the amount of FHLMC's
management and guaranty income as agreed upon between the seller and FHLMC. For
FHLMC Certificate Groups formed under the Guarantor Program with certificate
numbers beginning with 18-012, the range between the lowest and the highest
annual interest rates on the mortgage loans in a FHLMC Certificate group may not
exceed two percentage points.
 
     FHLMC Certificates duly presented for registration of ownership on or
before the last business day of a month are registered effective as of the first
day of the month. The first remittance to a registered holder of a FHLMC
Certificate will be distributed so as to be received normally by the 15th day of
the second month following the month in which the purchaser became a registered
holder of the FHLMC Certificates. Thereafter, such remittance will be
distributed monthly to the registered holder so as to be received normally by
the 15th day of each month. The Federal Reserve Bank of New York maintains
book-entry accounts with respect to FHLMC Certificates sold by FHLMC on or after
January 2, 1985, and makes payments of principal and interest each month to the
registered holders thereof in accordance with such holders' instructions.
 
     FHLMC also issues mortgage participation certificates representing an
undivided interest in a group of multi-family residential mortgage loans or
participations in multi-family residential mortgage loans purchased by FHLMC
("FHLMC Project Certificates"). The Prospectus Supplement for a Series of
Securities issued by a Trust Fund that includes FHLMC Project Certificates will
set forth additional information regarding multi-family residential mortgage
loans that qualify for purchase by FHLMC.
 
     Stripped Mortgage-Backed Securities.  Agency Securities may consist of one
or more stripped mortgage-backed securities, each as described herein and in the
related Prospectus Supplement. Each such Agency Security will represent an
undivided interest in all or part of either the principal distributions (but not
the interest distributions) or the interest distributions (but not the principal
distributions), or in some specified portion of the principal and interest
distributions (but not all of such distributions) on certain FHLMC, FNMA, GNMA
or other government agency or government-sponsored agency Certificates. The
underlying securities will be held under a trust agreement by FHLMC, FNMA, GNMA
or another government agency or government-sponsored agency, each as trustee, or
by another trustee named in the related Prospectus Supplement. FHLMC, FNMA, GNMA
or another government agency or government-sponsored agency will guarantee each
stripped Agency Security to the same extent as such entity guarantees the
underlying securities backing such stripped Agency Security, unless otherwise
specified in the related Prospectus Supplement.
 
     Other Agency Securities.  If specified in the related Prospectus
Supplement, a Trust Fund may include other mortgage pass-through certificates
issued or guaranteed by GNMA, FNMA, FHLMC or other government agencies or
government-sponsored agencies. The characteristics of any such mortgage pass-
 
                                       38
<PAGE>   40
 
through certificates will be described in such Prospectus Supplement. If so
specified, a combination of different types of Agency Securities may be held in
a Trust Fund.
 
PRIVATE MORTGAGE-BACKED SECURITIES
 
     General.  Private Mortgage-Backed Securities may consist of (a) mortgage
pass-through certificates evidencing an undivided interest in a pool of mortgage
loans, or (b) collateralized mortgage obligations ("CMO's") secured by mortgage
loans. Private Mortgage-Backed Securities will have been issued pursuant to a
PMBS agreement (the "PMBS Agreement"). The seller/servicer of the underlying
mortgage loans (the "PMBS Servicer") will have entered into the PMBS Agreement
with a trustee (the "PMBS Trustee") under the PMBS Agreement. The PMBS Trustee
or its agent, or a custodian, will possess the mortgage loans underlying such
Private Mortgage-Backed Security. Mortgage loans underlying a Private
Mortgage-Backed Security will be serviced by the PMBS Servicer directly or by
one or more sub-servicers who may be subject to the supervision of the PMBS
Servicer. The PMBS Servicer will be approved as a servicer by FNMA or FHLMC and,
if FHA Loans underlie the Private Mortgage-Backed Securities, approved by the
Department of Housing and Urban Development ("HUD") as an FHA mortgagee.
 
     The Issuer of the PMBS (the "PMBS Issuer") will be a financial institution
or other entity engaged generally in the business of mortgage lending or the
acquisition of mortgage loans, a public agency or instrumentality of a state,
local or federal government, or a limited purpose or other corporation organized
for the purpose of, among other things, establishing trusts and acquiring and
selling housing loans to such trusts and selling beneficial interests in such
trusts. If so specified in the Prospectus Supplement, the PMBS Issuer may be an
affiliate of the Depositor. If the PMBS Issuer is not an affiliate of the
Depositor, the related PMBS (i) will be acquired in the secondary market and not
pursuant to an initial offering of such PMBS, (ii) such PMBS Issuer will
generally not be involved in the issuance of the Securities other than as set
forth in the next two succeeding sentences and (iii) such PMBS will be freely
transferable pursuant to Rule 144(k) promulgated under the Securities Act of
1933, as amended. The obligations of the PMBS Issuer will generally be limited
to certain representations and warranties with respect to the assets conveyed by
it to the related trust. Unless otherwise specified in the related Prospectus
Supplement, the PMBS Issuer will not have guaranteed any of the assets conveyed
to the related trust or any of the Private Mortgage-Backed Securities issued
under the PMBS Agreement. Additionally, although the mortgage loans underlying
the Private Mortgage-Backed Securities may be guaranteed by an agency or
instrumentality of the United States, the Private Mortgage-Backed Securities
themselves will not be so guaranteed.
 
     Distributions of principal and interest will be made on the Private
Mortgage-Backed Securities on the dates specified in the related Prospectus
Supplement. The Private Mortgage-Backed Securities may be entitled to receive
nominal or no principal distributions or nominal or no interest distributions.
Principal and interest distributions will be made on the Private Mortgage-Backed
Securities by the PMBS Trustee or the PMBS Servicer. The PMBS Issuer or the PMBS
Servicer may have the right to repurchase assets underlying the Private
Mortgage-Backed Securities after a certain date or under other circumstances
specified in the related Prospectus Supplement.
 
     Underlying Loans.  The mortgage loans underlying the Private Mortgage-
Backed Securities may consist of fixed rate, level payment, fully amortizing or
graduated payment mortgage loans, buydown loans, adjustable rate mortgage loans,
or loans having balloon or other special payment features. Such mortgage loans
may be Single Family Loans, Multifamily Loans, Cooperative Loans or Contracts
secured by Manufactured Homes. As specified in the related Prospectus
Supplement, (i) no mortgage loan underlying the Private Mortgage-Backed
Securities will have had a Combined Loan-to-Value Ratio at origination in excess
of the percentage set forth in the related Prospectus Supplement, (ii) each
underlying mortgage loan will have had an original term to stated maturity of
not less than 5 years and not more than 40 years, (iii) each underlying mortgage
loan (other than Cooperative Loans) will be required to be covered by a standard
hazard insurance policy (which may be a blanket policy), and (iv) each mortgage
loan (other than Cooperative Loans or Contracts secured by a Manufactured Home)
will be covered by a title insurance policy.
 
                                       39

     Credit Support Relating to Private Mortgage-Backed Securities.  Credit
support in the form of subordination of other private mortgage certificates
issued under the PMBS Agreement, reserve funds, insurance policies, letters of
credit, financial guaranty insurance policies, guarantees or other types of
credit support may be provided with respect to the mortgage loans underlying the
Private Mortgage-Backed Securities or with respect to the Private
Mortgage-Backed Securities themselves.
 
     Additional Information.  The Prospectus Supplement for a Series for which
the related Trust Fund includes Private Mortgage-Backed Securities will specify
(i) the aggregate approximate principal amount and type of the Private
Mortgage-Backed Securities to be included in the Trust Fund, (ii) certain
characteristics of the mortgage loans underlying the Private Mortgage-Backed
Securities including (A) the payment features of such mortgage loans, (B) the
approximate aggregate principal balance, if known, of underlying mortgage loans
insured or guaranteed by a governmental entity, (C) the servicing fee or range
of servicing fees with respect to the underlying mortgage loans, and (D) the
minimum and maximum stated maturities of the underlying mortgage loans at
origination, (iii) the maximum original term-to-stated maturity of the Private
Mortgage-Backed Securities, (iv) the weighted average term-to-stated maturity of
the Private Mortgage-Backed Securities, (v) the pass-through or certificate rate
of the Private Mortgage-Backed Securities, (vi) the weighted average
pass-through or certificate rate of the Private Mortgage-Backed Securities,
(vii) the PMBS Issuer, the PMBS Servicer (if other than the PMBS Issuer) and the
PMBS Trustee for such Private Mortgage-Backed Securities, (viii) certain
characteristics of credit support, if any, such as reserve funds, insurance
policies, letters of credit or guarantees relating to the mortgage loans
underlying the Private Mortgage-Backed Securities or to such Private
Mortgage-Backed Securities themselves, (ix) the terms on which the underlying
mortgage loans for such Private Mortgage-Backed Securities may, or are required
to, be purchased prior to their stated maturity or the stated maturity of the
Private Mortgage-Backed Securities and (x) the terms on which other mortgage
loans may be substituted for those originally underlying the Private
Mortgage-Backed Securities.
 
REPRESENTATIONS BY SELLERS OR ORIGINATORS; REPURCHASES
 
     Each Seller or Originator will have made representations and warranties in
respect of the Loans sold by such Seller or originated by such Originator and
evidenced by all, or a part, of a Series of Securities. Except as otherwise
specified in the related Prospectus Supplement, such representations and
warranties include, among other things: (i) that title insurance (or in the case
of Properties located in areas where such policies are generally not available,
an attorney's certificate of title) and any required hazard insurance policy
were effective at origination of each Loan, other than a Cooperative Loan, and
that each policy (or certificate of title as applicable) remained in effect on
the date of purchase of the Loan from the Originator by the Seller or the
Depositor or from the Seller by or on behalf of the Depositor; (ii) that the
Seller or Originator had good title to each such Loan and such Loan was subject
to no offsets, defenses, counterclaims or rights of rescission except to the
extent that any buydown agreement may forgive certain indebtedness of a
borrower; (iii) that each Loan constituted a valid lien on, or a perfected
security interest with respect to, the Property (subject only to permissible
liens disclosed, if applicable, title insurance exceptions, if applicable, and
certain other exceptions described in the Agreement) and that the Property was
free from damage and was in acceptable condition; (iv) that there were no
delinquent tax or assessment liens against the Property; (v) that no required
payment on a Loan was delinquent more than the number of days specified in the
related Prospectus Supplement; and (vi) that each Loan was made in compliance
with, and is enforceable under, all applicable local, state and federal laws and
regulations in all material respects.
 
     If so specified in the related Prospectus Supplement, the representations
and warranties of a Seller or Originator in respect of a Loan will be made not
as of the Cut-off Date but as of the date on which such Originator sold the Loan
to the Seller or the Depositor or such Seller sold the Loan to the Depositor or
one of its affiliates. Under such circumstances, a substantial period of time
may have elapsed between the sale date and the date of initial issuance of the
Series of Securities evidencing an interest in such Loan. Since the
representations and warranties of a Seller or Originator do not address events
that may occur following the sale of a Loan by such Seller or Originator, its
repurchase obligation described below will not arise if the relevant event that
would otherwise have given rise to such an obligation with respect to a Loan
occurs after the date of
 
                                       40
<PAGE>   42
 
sale of such Loan by such Originator to the Seller or the Depositor or by such
Seller to the Depositor or its affiliates. However, the Depositor will not
include any Loan in the Trust Fund for any Series of Securities if anything has
come to the Depositor's attention that would cause it to believe that the
representations and warranties of a Seller or Originator will not be accurate
and complete in all material respects in respect of such Loan as of the date of
initial issuance of the related Series of Securities. If the Master Servicer is
also a Seller or Originator of Loans with respect to a particular Series of
Securities, such representations will be in addition to the representations and
warranties made by the Master Servicer in its capacity as a Master Servicer.
 
     The Master Servicer or the Trustee, if the Master Servicer is the Seller or
Originator, will promptly notify the relevant Seller or Originator of any breach
of any representation or warranty made by it in respect of a Loan which
materially and adversely affects the interests of the Securityholders in such
Loan. Unless otherwise specified in the related Prospectus Supplement, if such
Seller or Originator cannot cure such breach within 90 days following notice
from the Master Servicer or the Trustee, as the case may be, then such Seller or
Originator will be obligated either (i) to repurchase such Loan from the Trust
Fund at a price (the "Purchase Price") equal to 100% of the unpaid principal
balance thereof as of the date of the repurchase plus accrued interest thereon
to the first day of the month following the month of repurchase at the Loan Rate
(less any Advances or amount payable as related servicing compensation if the
Seller or Originator is the Master Servicer) or (ii) substitute for such Loan a
replacement loan that satisfies the criteria specified in the related Prospectus
Supplement. If a REMIC election is to be made with respect to a Trust Fund,
unless otherwise specified in the related Prospectus Supplement, the Master
Servicer or a holder of the related residual certificate generally will be
obligated to pay any prohibited transaction tax which may arise in connection
with any such repurchase or substitution and the Trustee must have received a
satisfactory opinion of counsel that such repurchase or substitution will not
cause the Trust Fund to lose its status as a REMIC or otherwise subject the
Trust Fund to a prohibited transaction tax. The Master Servicer may be entitled
to reimbursement for any such payment from the assets of the related Trust Fund
or from any holder of the related residual certificate. See "Description of the
Securities -- General." Except in those cases in which the Master Servicer is
the Seller or Originator, the Master Servicer will be required under the
applicable Agreement to enforce this obligation for the benefit of the Trustee
and the holders of the Securities, following the practices it would employ in
its good faith business judgment were it the owner of such Loan. This repurchase
or substitution obligation will constitute the sole remedy available to holders
of Securities or the Trustee for a breach of representation by a Seller or
Originator.
 
     Neither the Depositor nor the Master Servicer (unless the Master Servicer
is the Seller or Originator) will be obligated to purchase or substitute a Loan
if a Seller or Originator defaults on its obligation to do so, and no assurance
can be given that Sellers or Originators will carry out their respective
repurchase or substitution obligations with respect to Loans. However, to the
extent that a breach of a representation and warranty of a Seller or Originator
may also constitute a breach of a representation made by the Master Servicer,
the Master Servicer may have a repurchase or substitution obligation as
described below under "The Agreements -- Assignment of Trust Fund Assets."
 
SUBSTITUTION OF TRUST FUND ASSETS
 
     Substitution of Trust Fund Assets will be permitted in the event of
breaches of representations and warranties with respect to any original Trust
Fund Asset or in the event the documentation with respect to any Trust Fund
Asset is determined by the Trustee to be incomplete. The period during which
such substitution will be permitted generally will be indicated in the related
Prospectus Supplement. Substitution of Trust Fund Assets will be permitted if,
among other things, the credit criteria relating to the origination of the
initial Trust Fund Assets is the same as the credit criteria relating to the
origination of the substitute Trust Fund Assets. The related Prospectus
Supplement will describe any other conditions upon which Trust Fund Assets may
be substituted for Trust Fund Assets initially included in the Trust Fund.

<PAGE>   43
 
                                USE OF PROCEEDS
 
     The Depositor will apply all or substantially all of the net proceeds from
the sale of each Series of Securities for one or more of the following purposes:
(i) to purchase the related Trust Fund Assets, (ii) to establish any Pre-Funding
Account, Capitalized Interest Account or Reserve Account as described in the
related Prospectus Supplement and (iii) to pay the costs of structuring and
issuing such Securities, including the costs of obtaining any credit enhancement
as described under "Credit Enhancement". The Depositor expects to sell
Securities in Series from time to time, but the timing and amount of offerings
of Securities will depend on a number of factors, including the volume of Trust
Fund Assets acquired by the Depositor, prevailing interest rates, availability
of funds and general market conditions.
 
                                 THE DEPOSITOR
 
     Morgan Stanley ABS Capital I Inc., the Depositor, is a direct, wholly-owned
subsidiary of Morgan Stanley Group Inc. and was incorporated in the State of
Delaware on January 7, 1997. The principal executive offices of the Depositor
are located at 1585 Broadway, 2nd Floor, New York, New York 10036. Its telephone
number is (212) 761-4000. The Depositor does not have, nor is it expected in the
future to have, any significant assets.
 
     Neither the Depositor nor any of the Depositor's affiliates will insure or
guarantee distributions on the Securities of any Series.
 
                         DESCRIPTION OF THE SECURITIES
 
     Each Series of Certificates will be issued pursuant to separate agreements
(each, a "Pooling and Servicing Agreement" or a "Trust Agreement") among the
Depositor, the Master Servicer and the Trustee. A form of Pooling and Servicing
Agreement and Trust Agreement has been filed as an exhibit to the Registration
Statement of which this Prospectus forms a part. Each Series of Notes will be
issued pursuant to an indenture (the "Indenture") between the related Trust Fund
and the entity named in the related Prospectus Supplement as trustee (the
"Trustee") with respect to such Series, and the related Loans will be serviced
by the Master Servicer pursuant to a Master Servicing Agreement. A form of
Indenture and a form of Master Servicing Agreement have been filed as exhibits
to the Registration Statement of which this Prospectus forms a part. A Series of
Securities may consist of both Notes and Certificates. Each Agreement, dated as
of the related Cut-off Date, will be among the Depositor, the Master Servicer
and the Trustee for the benefit of the holders of the Securities of such Series.
The provisions of each Agreement will vary depending upon the nature of the
Securities to be issued thereunder and the nature of the related Trust Fund. The
following are descriptions of the material provisions which may appear in each
Agreement. The Prospectus Supplement for a Series of Securities will describe
any provision of the Agreement relating to such Series that mainly differs from
the description thereof contained in this Prospectus. The descriptions are
subject to, and are qualified in their entirety by reference to, all of the
provisions of the Agreement for each Series of Securities and the applicable
Prospectus Supplement.
 
GENERAL
 
     Unless otherwise specified in the related Prospectus Supplement, the
Securities of each Series will be issued in book-entry or fully registered form,
in the authorized denominations specified in the related Prospectus Supplement,
will, in the case of Certificates, evidence specified beneficial ownership
interests in, and in the case of Notes, be secured by, the assets of the related
Trust Fund created pursuant to each Agreement and will not be entitled to
payments in respect of the assets included in any other Trust Fund established
by the Depositor. Unless otherwise specified in the related Prospectus
Supplement, the Securities will not represent obligations of the Depositor or
any affiliate of the Depositor. Certain of the Loans may be guaranteed or
insured as set forth in the related Prospectus Supplement. Each Trust Fund will
consist of, to the extent provided in the related Agreement, (i) the Trust Fund
Assets, as from time to time are subject to the related Agreement (exclusive of
any amounts specified in the related Prospectus Supplement ("Retained
 
                                       42
<PAGE>   44
 
Interest")), including all payments of interest and principal received with
respect to the Loans after the Cut-off Date (to the extent not applied in
computing the principal balance of such Loans as of the Cut-off Date (the
"Cut-off Date Principal Balance")); (ii) such assets as from time to time are
required to be deposited in the related Security Account, as described below
under "The Agreements -- Payments on Loans; Deposits to Security Account"; (iii)
property which secured a Loan and which is acquired on behalf of the
Securityholders by foreclosure or deed in lieu of foreclosure and (iv) any
insurance policies or other forms of credit enhancement required to be
maintained pursuant to the related Agreement. If so specified in the related
Prospectus Supplement, a Trust Fund may also include one or more of the
following: reinvestment income on payments received on the Trust Fund Assets, a
Reserve Account, a mortgage pool insurance policy, a special hazard insurance
policy, a bankruptcy bond, one or more letters of credit, a surety bond,
guaranties or similar instruments or other agreements.
 
     Each Series of Securities will be issued in one or more classes. Each class
of Certificates of a Series will evidence beneficial ownership of a specified
percentage (which may be 0%) or portion of future interest payments and a
specified percentage (which may be 0%) or portion of future principal payments
on, and each class of Notes of a Series will be secured by, the related Trust
Fund Assets. A Series of Securities may include one or more classes that are
senior in right to payment to one or more other classes of Securities of such
Series. Certain Series or classes of Securities may be covered by insurance
policies, surety bonds or other forms of credit enhancement, in each case as
described under "Credit Enhancement" herein and in the related Prospectus
Supplement. One or more classes of Securities of a Series may be entitled to
receive distributions of principal, interest or any combination thereof.
Distributions on one or more classes of a Series of Securities may be made prior
to one or more other classes, after the occurrence of specified events, in
accordance with a schedule or formula or on the basis of collections from
designated portions of the related Trust Fund Assets, in each case as specified
in the related Prospectus Supplement. The timing and amounts of such
distributions may vary among classes or over time as specified in the related
Prospectus Supplement.
 
     Distributions of principal and interest (or, where applicable, of principal
only or interest only) on the related Securities will be made by the Trustee on
each Distribution Date (i.e., monthly, quarterly, semi-annually or at such other
intervals and on the dates as are specified in the related Prospectus
Supplement) in proportion to the percentages specified in the related Prospectus
Supplement. Distributions will be made to the persons in whose names the
Securities are registered at the close of business on the dates specified in the
related Prospectus Supplement (each, a "Record Date"). Distributions will be
made in the manner specified in the related Prospectus Supplement to the persons
entitled thereto at the address appearing in the register maintained for holders
of Securities (the "Security Register"); provided, however, that the final
distribution in retirement of the Securities will be made only upon presentation
and surrender of the Securities at the office or agency of the Trustee or other
person specified in the notice to Securityholders of such final distribution.
 
     The Securities will be freely transferable and exchangeable at the
Corporate Trust Office of the Trustee as set forth in the related Prospectus
Supplement. No service charge will be made for any registration of exchange or
transfer of Securities of any Series, but the Trustee may require payment of a
sum sufficient to cover any related tax or other governmental charge.
 
     Under current law the purchase and holding of a class of Securities
entitled only to a specified percentage of payments of either interest or
principal or a notional amount of either interest or principal on the related
Loans or a class of Securities entitled to receive payments of interest and
principal on the Loans only after payments to other classes or after the
occurrence of certain specified events by or on behalf of any employee benefit
plan or other retirement arrangement (including individual retirement accounts
and annuities, Keogh plans and collective investment funds in which such plans,
accounts or arrangements are invested) subject to provisions of ERISA or the
Code, may result in prohibited transactions, within the meaning of ERISA and the
Code. See "ERISA Considerations." Unless otherwise specified in the related
Prospectus Supplement, the transfer of Securities of such a class will not be
registered unless the transferee (i) represents that it is not, and is not
purchasing on behalf of, any such plan, account or arrangement or (ii) provides
an opinion of counsel satisfactory to the Trustee and the Depositor that the
purchase of Securities of such a class by or on behalf of such plan, account or
arrangement is permissible under applicable law and will not subject the
Trustee, the
 
                                       43
<PAGE>   45
 
Master Servicer or the Depositor to any obligation or liability in addition to
those undertaken in the Agreements.
 
     As to each Series, an election may be made to treat the related Trust Fund
or designated portions thereof as a "real estate mortgage investment conduit" or
"REMIC" as defined in the Code. The related Prospectus Supplement will specify
whether a REMIC election is to be made. Alternatively, the Agreement for a
Series may provide that a REMIC election may be made at the discretion of the
Depositor or the Master Servicer and may only be made if certain conditions are
satisfied. As to any such Series, the terms and provisions applicable to the
making of a REMIC election will be set forth in the related Prospectus
Supplement. If such an election is made with respect to a Series, one of the
classes will be designated as evidencing the sole class of "residual interests"
in the related REMIC, as defined in the Code. All other classes of Securities in
such a Series will constitute "regular interests" in the related REMIC, as
defined in the Code. As to each Series with respect to which a REMIC election is
to be made, the Trustee, the Master Servicer or a holder of the related residual
certificate will be obligated to take all actions required in order to comply
with applicable laws and regulations and will be obligated to pay any prohibited
transaction taxes. The Trustee or the Master Servicer, unless otherwise provided
in the related Prospectus Supplement, will be entitled to reimbursement for any
such payment from the assets of the Trust Fund or from any holder of the related
residual certificate.
 
INDEXED SECURITIES
 
     To the extent specified in any Prospectus Supplement, any class of
Securities of a given Series may consist of Securities ("Indexed Securities") in
which the principal amount payable at the final scheduled payment date (the
"Indexed Principal Amount") is determined by reference to a measure (the
"Index") which will be related to (i) the difference in the rate of exchange
between United States dollars and a currency or composite currency (the "Indexed
Currency") specified in the applicable Prospectus Supplement (such Indexed
Securities, "Currency Indexed Securities"); (ii) the difference in the price of
a specified commodity (the "Indexed Commodity") on specified dates (such Indexed
Securities, "Commodity Indexed Securities"); (iii) the difference in the level
of a specified stock index (the "Stock Index"), which may be based on U.S. or
foreign stocks, on specified dates (such Indexed Securities, "Stock Indexed
Securities"); or (iv) such other objective price or economic measures as are
described in the applicable Prospectus Supplement. The manner of determining the
Indexed Currency, the Indexed Commodity, the Stock Index or other price or
economic measures used in such determination will be set forth in the applicable
Prospectus Supplement, together with information concerning tax consequences to
the holders of such Indexed Securities.
 
     If the determination of the Indexed Principal Amount of an Indexed Security
is based on an Index calculated or announced by a third party and such third
party either suspends the calculation or announcement of such Index or changes
the basis upon which such Index is calculated (other than changes consistent
with policies in effect at the time such Indexed Security was issued and
permitted changes described in the applicable Prospectus Supplement), then such
Index shall be calculated for purposes of such Indexed Security by an
independent calculation agent named in the applicable Prospectus Supplement on
the same basis, and subject to the same conditions and controls, as applied to
the original third party. If for any reason such Index cannot be calculated on
the same basis and subject to the same conditions and controls as applied to the
original third party, then the Indexed Principal Amount of such Indexed Security
will be calculated in the manner set forth in the applicable Prospectus
Supplement. Any determination of such independent calculation agent will in the
absence of manifest error be binding on all parties.
 
     Interest on an Indexed Security will be payable based on the amount
designated in the applicable Prospectus Supplement (the "Face Amount"). The
applicable Prospectus Supplement will describe whether the principal amount of
the related Indexed Security, if any, that would be payable upon redemption or
repayment prior to the applicable final scheduled Distribution Date will be the
Face Amount of the Indexed Security, the Indexed Principal Amount of such
Indexed Security at the time of redemption or repayment, or another amount
described in such Prospectus Supplement.

DISTRIBUTIONS ON SECURITIES
 
     General.  In general, the method of determining the amount of distributions
on a particular Series of Securities will depend on the type of credit support,
if any, that is used with respect to such Series. See "Credit Enhancement." Set
forth below are descriptions of various methods that may be used to determine
the amount of distributions on the Securities of a particular Series. The
Prospectus Supplement for each Series of Securities will describe the method to
be used in determining the amount of distributions on the Securities of such
Series.
 
     Distributions allocable to principal and interest on the Securities will be
made by the Trustee out of, and only to the extent of, funds in the related
Security Account, including any funds transferred from any Reserve Account (a
"Reserve Account"). As between Securities of different classes and as between
distributions of principal (and, if applicable, between distributions of
Principal Prepayments, as defined below, and scheduled payments of principal)
and interest, distributions made on any Distribution Date will be applied as
specified in the related Prospectus Supplement. The Prospectus Supplement will
also describe the method for allocating the distributions among Securities of a
particular class.
 
     Available Funds.  All distributions on the Securities of each Series on
each Distribution Date will be made from the Available Funds described below, in
accordance with the terms described in the related Prospectus Supplement and
specified in the Agreement. "Available Funds" for each Distribution Date will
generally equal the amount on deposit in the related Security Account on such
Distribution Date (net of related fees and expenses payable by the related Trust
Fund) other than amounts to be held therein for distribution on future
Distribution Dates.
 
     Distributions of Interest.  Interest will accrue on the aggregate principal
balance of the Securities (or, in the case of Securities entitled only to
distributions allocable to interest, the aggregate notional amount) of each
class of Securities (the "Class Security Balance") entitled to interest from the
date, at the Pass-Through Rate or interest rate, as applicable (which in either
case may be a rate per annum specified, or calculated in the method described,
in such Prospectus Supplement), and for the periods specified in such Prospectus
Supplement. To the extent funds are available therefor, interest accrued during
each such specified period on each class of Securities entitled to interest
(other than a class of Securities that provides for interest that accrues, but
is not currently payable, referred to hereafter as "Accrual Securities") will be
distributable on the Distribution Dates specified in the related Prospectus
Supplement until the aggregate Class Security Balance of the Securities of such
class has been distributed in full or, in the case of Securities entitled only
to distributions allocable to interest, until the aggregate notional amount of
such Securities is reduced to zero or for the period of time designated in the
related Prospectus Supplement. The original Class Security Balance of each
Security will equal the aggregate distributions allocable to principal to which
such Security is entitled. Distributions allocable to interest on each Security
that is not entitled to distributions allocable to principal will be calculated
based on the notional amount of such Security. The notional amount of a Security
will not evidence an interest in or entitlement to distributions allocable to
principal but will be used solely for convenience in expressing the calculation
of interest and for certain other purposes.
 
     Interest payable on the Securities of a Series on a Distribution Date will
include all interest accrued during the period specified in the related
Prospectus Supplement. In the event interest accrues over a period ending two or
more days prior to a Distribution Date, the effective yield to Securityholders
will be reduced from the yield that would otherwise be obtainable if interest
payable on the Security were to accrue through the day immediately preceding
such Distribution Date, and the effective yield (at par) to Securityholders will
be less than the indicated coupon rate.
 
     With respect to any class of Accrual Securities, if specified in the
related Prospectus Supplement, any interest that has accrued but is not paid on
a given Distribution Date will be added to the aggregate Class Security Balance
of such class of Securities on that Distribution Date. Distributions of interest
on any class of Accrual Securities will commence only after the occurrence of
the events specified in such Prospectus Supplement. Prior to such time, the
beneficial ownership interest in the Trust Fund or the principal balance, as
applicable, of such class of Accrued Securities, as reflected in the aggregate
Class Security Balance of such class of Accrual Securities, will increase on
each Distribution Date by the amount of interest that accrued on
 
                                       45
<PAGE>   47
 
such class of Accrual Securities during the preceding interest accrual period
but that was not required to be distributed to such class on such Distribution
Date. Any such class of Accrual Securities will thereafter accrue interest on
its outstanding Class Security Balance as so adjusted.
 
     Distributions of Principal.  The related Prospectus Supplement will specify
the method by which the amount of principal to be distributed on the Securities
on each Distribution Date will be calculated and the manner in which such amount
will be allocated among the classes of Securities entitled to distributions of
principal. The aggregate Class Security Balance of any class of Securities
entitled to distributions of principal generally will be the aggregate original
Class Security Balance of such class of Securities specified in such Prospectus
Supplement, reduced by all distributions reported to the holders of such
Securities as allocable to principal and, (i) in the case of Accrual Securities,
unless otherwise specified in the related Prospectus Supplement, increased by
all interest accrued but not then distributable on such Accrual Securities and
(ii) in the case of adjustable rate Securities, subject to the effect of
negative amortization, if applicable.
 
     If so provided in the related Prospectus Supplement, one or more classes of
Securities will be entitled to receive all or a disproportionate percentage of
the payments of principal which are received from borrowers, including payments
received in advance of their scheduled due dates and are not accompanied by
amounts representing scheduled interest due after the month of such payments
("Principal Prepayments") in the percentages and under the circumstances or for
the periods specified in such Prospectus Supplement. Any such allocation of
principal payments to such class or classes of Securities will have the effect
of accelerating the amortization of such Securities while increasing the
interests evidenced by one or more other classes of Securities in the Trust
Fund. Increasing the interests of the other classes of Securities relative to
that of certain Securities is intended to preserve the availability of the
subordination provided by such other Securities. See "Credit
Enhancement -- Subordination."
 
     Unscheduled Distributions.  If specified in the related Prospectus
Supplement, the Securities will be subject to receipt of distributions before
the next scheduled Distribution Date under the circumstances and in the manner
described below and in such Prospectus Supplement. If applicable, the Trustee
will be required to make such unscheduled distributions on the day and in the
amount specified in the related Prospectus Supplement if, due to substantial
payments of principal (including Principal Prepayments) on the Trust Fund
Assets, the Trustee or the Master Servicer determines that the funds available
or anticipated to be available from the Security Account and, if applicable, any
Reserve Account, may be insufficient to make required distributions on the
Securities on such Distribution Date. Unless otherwise specified in the related
Prospectus Supplement, the amount of any such unscheduled distribution that is
allocable to principal will not exceed the amount that would otherwise have been
required to be distributed as principal on the Securities on the next
Distribution Date. Unless otherwise specified in the related Prospectus
Supplement, the unscheduled distributions will include interest at the
applicable Pass-Through Rate (if any) or interest rate (if any) on the amount of
the unscheduled distribution allocable to principal for the period and to the
date specified in such Prospectus Supplement.
 
ADVANCES
 
     To the extent provided in the related Prospectus Supplement, the Master
Servicer will be required to advance on or before each Distribution Date (from
its own funds, funds advanced by Sub-Servicers or funds held in the Security
Account for future distributions to the holders of Securities of the related
Series), an amount equal to the aggregate of payments of interest and/or
principal that were delinquent on the related Determination Date (as such term
is defined in the related Prospectus Supplement) and were not advanced by any
Sub-Servicer, net of the Servicing Fee if so specified in the related Prospectus
Supplement, subject to the Master Servicer's determination that such advances
may be recoverable out of late payments by borrowers, Liquidation Proceeds,
Insurance Proceeds or otherwise. In the case of Cooperative Loans, the Master
Servicer also may be required to advance any unpaid maintenance fees and other
charges under the related proprietary leases as specified in the related
Prospectus Supplement. In addition, to the extent provided in the related
Prospectus Supplement, a cash account may be established to provide for Advances
to be made in the event of certain Trust Fund Assets payment defaults or
collection shortfalls.
 
                                       46
<PAGE>   48
 
     In making Advances, the Master Servicer will endeavor to maintain a regular
flow of scheduled interest and principal payments to holders of the Securities,
rather than to guarantee or insure against losses. If Advances are made by the
Master Servicer from cash being held for future distribution to Securityholders,
the Master Servicer will replace such funds on or before any future Distribution
Date to the extent that funds in the applicable Security Account on such
Distribution Date would be less than the amount required to be available for
distributions to Securityholders on such date. Any Master Servicer funds
advanced will be reimbursable to the Master Servicer out of recoveries on the
specific Loans with respect to which such Advances were made (e.g., late
payments made by the related borrower, any related Insurance Proceeds,
Liquidation Proceeds or proceeds of any Loan purchased by the Depositor, a
Sub-Servicer or a Seller pursuant to the related Agreement). Advances by the
Master Servicer (and any advances by a Sub-Servicer) also will be reimbursable
to the Master Servicer (or Sub-Servicer) from cash otherwise distributable to
Securityholders (including the holders of Senior Securities) to the extent that
the Master Servicer determines that any such Advances previously made are not
ultimately recoverable as described above. To the extent provided in the related
Prospectus Supplement, the Master Servicer also will be obligated to make
Advances, to the extent recoverable out of Insurance Proceeds, Liquidation
Proceeds or otherwise, in respect of certain taxes and insurance premiums not
paid by borrowers on a timely basis. Funds so advanced are reimbursable to the
Master Servicer to the extent permitted by the related Agreement. The
obligations of the Master Servicer to make advances may be supported by a cash
advance reserve fund, a surety bond or other arrangement, in each case as
described in the related Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, in the
event the Master Servicer or a Sub-Servicer fails to make a required Advance,
the Trustee will be obligated to make such Advance in its capacity as successor
servicer. If the Trustee makes such an Advance, it will be entitled to be
reimbursed for such Advance to the same extent and degree as the Master Servicer
or a Sub-Servicer is entitled to be reimbursed for Advances. See
"-- Distributions on Securities" above.
 
REPORTS TO SECURITYHOLDERS
 
     Prior to or concurrently with each distribution on a Distribution Date, the
Master Servicer or the Trustee will furnish to each Securityholder of record of
the related Series a statement setting forth, to the extent applicable to such
Series of Securities, among other things:
 
          (i) the amount of such distribution allocable to principal, separately
     identifying the aggregate amount of any Principal Prepayments and if so
     specified in the related Prospectus Supplement, any applicable prepayment
     penalties included therein;
 
          (ii) the amount of such distribution allocable to interest;
 
          (iii) the amount of any Advance;
 
          (iv) the aggregate amount (a) otherwise allocable to the Subordinated
     Securityholders on such Distribution Date, and (b) withdrawn from the
     Reserve Account, if any, that is included in the amounts distributed to the
     Senior Securityholders;
 
          (v) the outstanding principal balance or notional amount of each class
     of the related Series after giving effect to the distribution of principal
     on such Distribution Date;
 
          (vi) the percentage of principal payments on the Loans (excluding
     prepayments), if any, which each such class will be entitled to receive on
     the following Distribution Date;
 
          (vii) the percentage of Principal Prepayments on the Loans, if any,
     which each such class will be entitled to receive on the following
     Distribution Date;
 
          (viii) the related amount of the servicing compensation retained or
     withdrawn from the Security Account by the Master Servicer, and the amount
     of additional servicing compensation received by the Master Servicer
     attributable to penalties, fees, excess Liquidation Proceeds and other
     similar charges and items;
 
                                       47
<PAGE>   49
 
          (ix) the number and aggregate principal balances of Loans (A)
     delinquent (exclusive of Loans in foreclosure) (1) 1 to 30 days, (2) 31 to
     60 days, (3) 61 to 90 days and (4) 91 or more days and (B) in foreclosure
     and delinquent (1) 1 to 30 days, (2) 31 to 60 days, (3) 61 to 90 days and
     (4) 91 or more days, as of the close of business on the last day of the
     calendar month preceding such Distribution Date;
 
          (x) the book value of any real estate acquired through foreclosure or
     grant of a deed in lieu of foreclosure;

CATEGORIES OF CLASSES OF SECURITIES
 
     The Securities of any Series may be comprised of one or more classes. Such
classes, in general, fall into different categories. The following chart
identifies and generally defines certain of the more typical categories. The
Prospectus Supplement for a series of Securities may identify the classes which
comprise such Series by reference to the following categories.

Principal Types
- ----------------
Accretion Directed...........................    A class that receives principal payments from the
                                                 accreted interest from specified Accrual classes. An
                                                 Accretion Directed class also may receive principal
                                                 payments from principal paid on the underlying Trust
                                                 Fund Assets for the related Series.
Component Securities.........................    A class consisting of "Components." The Components
                                                 of a class of Component Securities may have
                                                 different principal and/or interest payment
                                                 characteristics but together constitute a single
                                                 class. Each Component of a class of Component
                                                 Securities may be identified as falling into one or
                                                 more of the categories in this chart.

<S>                                              <C>
Notional Amount Securities...................    A class having no principal balance and bearing
                                                 interest on the related notional amount. The
                                                 notional amount is used for purposes of the
                                                 determination of interest distributions.
Planned Principal Class (also sometimes
  referred to as "PACs").....................    A class that is designed to receive principal
                                                 payments using a predetermined principal balance
                                                 schedule derived by assuming two constant prepayment
                                                 rates for the underlying Trust Fund Assets. These
                                                 two rates are the endpoints for the "structuring
                                                 range" for the Planned Principal Class. The Planned
                                                 Principal Classes in any Series of Securities may be
                                                 subdivided into different categories (e.g., Primary
                                                 Planned Principal Classes, Secondary Planned
                                                 Principal Classes and so forth) having different
                                                 effective structuring ranges and different principal
                                                 payment priorities. The structuring range for the
                                                 Secondary Planned Principal Class of a Series of
                                                 Securities will be narrower than that for the
                                                 Primary Planned Principal Class of such Series.
Scheduled Principal Class....................    A class that is designed to receive principal
                                                 payments using a predetermined principal balance
                                                 schedule but is not designated as a Planned
                                                 Principal Class or Targeted Principal Class. In many
                                                 cases, the schedule is derived by assuming two
                                                 constant prepayment rates for the underlying Trust
                                                 Fund Assets. These two rates are the endpoints for
                                                 the "structuring range" for the Scheduled Principal
                                                 Class.
Sequential Pay Class.........................    Classes that receive principal payments in a
                                                 prescribed sequence, that do not have predetermined
                                                 principal balance schedules and that under all
                                                 circumstances receive payments of principal
                                                 continuously from the first Distribution Date on
                                                 which they receive principal until they are retired.
                                                 A single class that receives principal payments
                                                 before or after all other classes in the same Series
                                                 of Securities may be identified as a Sequential Pay
                                                 Class.
Strip........................................    A class that receives a constant proportion, or
                                                 "strip," of the principal payments on the underlying
                                                 Trust Fund Assets.
Support Class (also sometimes referred to as
  "companion classes").......................    A class that receives principal payments on any
                                                 Distribution Date only if scheduled payments have
                                                 been made on specified Planned Principal Classes,
                                                 Targeted Principal Classes and/or Scheduled
                                                 Principal Classes on such Distribution Date.
Targeted Principal Class (also sometimes
  referred to as "TACs").....................    A class that is designed to receive principal
                                                 payments using a predetermined principal balance
                                                 schedule derived by assuming a single constant
                                                 prepayment rate for the underlying Trust Fund
                                                 Assets.

Interest Types
- ---------------
Fixed Rate...................................    A class with an interest rate that is fixed
                                                 throughout the life of the class.
Floating Rate................................    A class with an interest rate that resets
                                                 periodically based upon a designated index and that
                                                 varies directly with changes in such index as
                                                 specified in the related Prospectus Supplement.
                                                 Interest payable to a Floating Rate class on a
                                                 Distribution Date may be subject to a cap based on
                                                 the amount of funds available to pay interest on
                                                 such Distribution Date.
Inverse Floating Rate........................    A class with an interest rate that resets
                                                 periodically based upon a designated index as
                                                 specified in the related Prospectus Supplement and
                                                 that varies inversely with changes in such index.
Variable Rate................................    A class with an interest rate that resets
                                                 periodically and is calculated by reference to the
                                                 rate or rates of interest applicable to specified
                                                 assets or instruments (e.g., the Loan Rates borne by
                                                 the underlying Loans).
Auction Rate.................................    A class with an interest rate that resets
                                                 periodically to an auction rate that is calculated
                                                 on the basis of auction procedures described in the
                                                 related Prospectus Supplement.
Interest Only................................    A class that receives some or all of the interest
                                                 payments made on the underlying Trust Fund Assets or
                                                 other assets of the Trust Fund and little or no
                                                 principal. Interest Only classes have either a
                                                 nominal principal balance or a notional amount. A
                                                 nominal principal balance represents actual
                                                 principal that will be paid on the class. It is
                                                 referred to as nominal since it is extremely small
                                                 compared to other classes. A notional amount is the
                                                 amount used as a reference to calculate the amount
                                                 of interest due on an Interest Only class that is
                                                 not entitled to any distributions in respect of
                                                 principal.
Principal Only...............................    A class that does not bear interest and is entitled
                                                 to receive only distributions in respect of
                                                 principal.
Partial Accrual..............................    A class that accretes a portion of the amount of
                                                 accrued interest thereon, which amount will be added
                                                 to the principal balance of such class on each
                                                 applicable Distribution Date, with the remainder of
                                                 such accrued interest to be distributed currently as
                                                 interest on such class. Such accretion may continue
                                                 until a specified event has occurred or until such
                                                 Partial Accrual class is retired.
Accrual......................................    A class that accretes the amount of accrued interest
                                                 otherwise distributable on such class, which amount
                                                 will be added as principal to the principal balance
                                                 of such class on each applicable Distribution Date.
                                                 Such accretion may continue until some specified
                                                 event has occurred or until such Accrual Class is
                                                 retired.

INDICES APPLICABLE TO FLOATING RATE AND INVERSE FLOATING RATE CLASSES
 
     Unless otherwise specified in the related Prospectus Supplement, the
indices applicable to Floating Rate and Inverse Floating Rate Classes either
will be LIBOR, the Eleventh District Cost of Funds Index, the Treasury Index or
the Prime Rate, in each case calculated as described below.
 
LIBOR
 
     Unless otherwise specified in the related Prospectus Supplement, on the
LIBOR Determination Date (as such term is defined in the related Prospectus
Supplement) for each class of Securities of a Series as to which the applicable
interest rate is determined by reference to an index denominated as LIBOR, the
Person designated in the related Agreement (the "Calculation Agent") will
determine LIBOR by reference to the quotations, as set forth on the Reuters
Screen LIBO Page (as defined in the International Swap Dealers Association, Inc.
Code of Standard Wording, Assumptions and Provisions for Swaps, 1986 Edition),
offered by the principal London office of each of the designated reference banks
meeting the criteria set forth below (the "Reference Banks") for making
one-month United States dollar deposits in leading banks in the London Interbank
market, as of 11:00 a.m. (London time) on such LIBOR Determination Date. In lieu
of relying on the quotations for those Reference Banks that appear at such time
on the Reuters Screen LIBO Page, the Calculation Agent will request each of the
Reference Banks to provide such offered quotations at such time.
 
     LIBOR will be established by the Calculation Agent on each LIBOR
Determination Date as follows:
 
          (a) If on any LIBOR Determination Date two or more Reference Banks
     provide such offered quotations, LIBOR for the next Interest Accrual Period
     (as such term is defined in the related Prospectus Supplement) shall be the
     arithmetic mean of such offered quotations (rounded upwards if necessary to
     the nearest whole multiple of 1/32%).
 
          (b) If on any LIBOR Determination Date only one or none of the
     Reference Banks provides such offered quotations, LIBOR for the next
     Interest Accrual Period shall be whichever is the higher of (i) LIBOR as
     determined on the previous LIBOR Determination Date or (ii) the Reserve
     Interest Rate. The "Reserve Interest Rate" shall be the rate per annum
     which the Calculation Agent determines to be either (i) the arithmetic mean
     (rounded upwards if necessary to the nearest whole multiple of 1/32%) of
     the one-month United States dollar lending rates that New York City banks
     selected by the Calculation Agent are quoting, on the relevant LIBOR
     Determination Date, to the principal London offices of at least two of the
     Reference Banks to which such quotations are, in the opinion of the
     Calculation Agent, being so made, or (ii) in the event that the Calculation
     Agent can determine no such arithmetic mean, the lowest one-month United
     States dollar lending rate which New York City banks selected by the
     Calculation Agent are quoting on such LIBOR Determination Date to leading
     European banks.
 
          (c) If on any LIBOR Determination Date for a class specified in the
     related Prospectus Supplement, the Calculation Agent is required but is
     unable to determine the Reserve Interest Rate in the manner provided in
     paragraph (b) above, LIBOR for the next Interest Accrual Period shall be
     LIBOR as determined on the preceding LIBOR Determination Date, or, in the
     case of the first LIBOR Determination Date, LIBOR shall be deemed to be the
     per annum rate specified as such in the related Prospectus Supplement.
 
     Each Reference Bank (i) shall be a leading bank engaged in transactions in
Eurodollar deposits in the international Eurocurrency market; (ii) shall not
control, be controlled by, or be under common control with the Calculation
Agent; and (iii) shall have an established place of business in London. If any
such Reference Bank should be unwilling or unable to act as such or if
appointment of any such Reference Bank is terminated, another leading bank
meeting the criteria specified above will be appointed.
 
     The establishment of LIBOR on each LIBOR Determination Date by the
Calculation Agent and its calculation of the rate of interest for the applicable
classes for the related Interest Accrual Period shall (in the absence of
manifest error) be final and binding.

COFI
 
     The Eleventh District Cost of Funds Index is designed to represent the
monthly weighted average cost of funds for savings institutions in Arizona,
California and Nevada that are member institutions of the Eleventh Federal Home
Loan Bank District (the "Eleventh District"). The Eleventh District Cost of
Funds Index for a particular month reflects the interest costs paid on all types
of funds held by Eleventh District member institutions and is calculated by
dividing the cost of funds by the average of the total amount of those funds
outstanding at the end of that month and of the prior month and annualizing and
adjusting the result to reflect the actual number of days in the particular
month. If necessary, before these calculations are made, the component figures
are adjusted by the Federal Home Loan Bank of San Francisco ("FHLBSF") to
neutralize the effect of events such as member institutions leaving the Eleventh
District or acquiring institutions outside the Eleventh District. The Eleventh
District Cost of Funds Index is weighted to reflect the relative amount of each
type of funds held at the end of the relevant month. The major components of
funds of Eleventh District member institutions are: (i) savings deposits, (ii)
time deposits, (iii) FHLBSF advances, (iv) repurchase agreements and (v) all
other borrowings. Because the component funds represent a variety of maturities
whose costs may react in different ways to changing conditions, the Eleventh
District Cost of Funds Index does not necessarily reflect current market rates.
 
     A number of factors affect the performance of the Eleventh District Cost of
Funds Index, which may cause it to move in a manner different from indices tied
to specific interest rates, such as United States Treasury bills or LIBOR.
Because the liabilities upon which the Eleventh District Cost of Funds Index is
based were issued at various times under various market conditions and with
various maturities, the Eleventh District Cost of Funds Index may not
necessarily reflect the prevailing market interest rates on new liabilities of
similar maturities. Moreover, as stated above, the Eleventh District Cost of
Funds Index is designed to represent the average cost of funds for Eleventh
District savings institutions for the month prior to the month in which it is
due to be published. Additionally, the Eleventh District Cost of Funds Index may
not necessarily move in the same direction as market interest rates at all
times, since as longer term deposits or borrowings mature and are renewed at
prevailing market interest rates, the Eleventh District Cost of Funds Index is
influenced by the differential between the prior and the new rates on those
deposits or borrowings. In addition, movements of the Eleventh District Cost of
Funds Index, as compared to other indices tied to specific interest rates, may
be affected by changes instituted by the FHLBSF in the method used to calculate
the Eleventh District Cost of Funds Index.
 
     The FHLBSF publishes the Eleventh District Cost of Funds Index in its
monthly Information Bulletin. Any individual may request regular receipt by mail
of Information Bulletins by writing the Federal Home Loan Bank of San Francisco,
P.O. Box 7948, 600 California Street, San Francisco, California 94120, or by
calling (415) 616-1000. The Eleventh District Cost of Funds Index may also be
obtained by calling the FHLBSF at (415) 616-2600.
 
     The FHLBSF has stated in its Information Bulletin that the Eleventh
District Cost of Funds Index for a month "will be announced on or near the last
working day" of the following month and also has stated that it "cannot
guarantee the announcement" of such index on an exact date. So long as such
index for a month is announced on or before the tenth day of the second
following month, the interest rate for each class of Securities of a Series as
to which the applicable interest rate is determined by reference to an index
denominated as COFI (each, a class of "COFI Securities") for the Interest
Accrual Period commencing in such second following month will be based on the
Eleventh District Cost of Funds Index for the second preceding month. If
publication is delayed beyond such tenth day, such interest rate will be based
on the Eleventh District Cost of Funds Index for the third preceding month.
 
     Unless otherwise specified in the related Prospectus Supplement, if on the
tenth day of the month in which any Interest Accrual Period commences for a
class of COFI Securities the most recently published Eleventh District Cost of
Funds Index relates to a month prior to the third preceding month, the index for
such current Interest Accrual Period and for each succeeding Interest Accrual
Period will, except as described in the next to last sentence of this paragraph,
be based on the National Monthly Median Cost of Funds Ratio to SAIF-Insured
Institutions (the "National Cost of Funds Index") published by the Office of
Thrift
 
                                       52
<PAGE>   54
 
Supervision (the "OTS") for the third preceding month (or the fourth preceding
month if the National Cost of Funds Index for the third preceding month has not
been published on such tenth day of an Interest Accrual Period). Information on
the National Cost of Funds Index may be obtained by writing the OTS at 1700 G
Street, N.W., Washington, D.C. 20552 or calling (202) 906-6677, and the current
National Cost of Funds Index may be obtained by calling (202) 906-6988. If on
any such tenth day of the month in which an Interest Accrual Period commences
the most recently published National Cost of Funds Index relates to a month
prior to the fourth preceding month, the applicable index for such Interest
Accrual Period and each succeeding Interest Accrual Period will be based on
LIBOR, as determined by the Calculation Agent in accordance with the Agreement
relating to such Series of Securities. A change of index from the Eleventh
District Cost of Funds Index to an alternative index will result in a change in
the index level, and, particularly if LIBOR is the alternative index, could
increase its volatility.
 
     The establishment of COFI by the Calculation Agent and its calculation of
the rates of interest for the applicable classes for the related Interest
Accrual Period shall (in the absence of manifest error) be final and binding.
 
TREASURY INDEX
 
     Unless otherwise specified in the related Prospectus Supplement, on the
Treasury Index Determination Date (as such term is defined in the related
Prospectus Supplement) for each class of Securities of a Series as to which the
applicable interest rate is determined by reference to an index denominated as a
Treasury Index, the Calculation Agent will ascertain the Treasury Index for
Treasury securities of the maturity and for the period (or, if applicable, date)
specified in the related Prospectus Supplement. Unless otherwise specified in
the related Prospectus Supplement, the Treasury Index for any period means the
average of the yield for each business day during the period specified therein
(and for any date means the yield for such date), expressed as a per annum
percentage rate, on (i) U.S. Treasury securities adjusted to the "constant
maturity" (as further described below) specified in such Prospectus Supplement
or (ii) if no "constant maturity" is so specified, U.S. Treasury securities
trading on the secondary market having the maturity specified in such Prospectus
Supplement, in each case as published by the Federal Reserve Board in its
Statistical Release No. H.15(519). Statistical Release No. H.15(519) is
published on Monday or Tuesday of each week and may be obtained by writing or
calling the Publications Department at the Board of Governors of the Federal
Reserve System, 21st and C Streets, Washington, D.C. 20551 (202) 452-3244. If
the Calculation Agent has not yet received Statistical Release No. H.15(519) for
such week, then it will use such Statistical Release from the immediately
preceding week.
 
     Yields on U.S. Treasury securities at "constant maturity" are derived from
the U.S. Treasury's daily yield curve. This curve, which relates the yield on a
security to its time to maturity, is based on the closing market bid yields on
actively traded Treasury securities in the over-the-counter market. These market
yields are calculated from composites of quotations reported by five leading
U.S. Government securities dealers to the Federal Reserve Bank of New York. This
method provides a yield for a given maturity even if no security with that exact
maturity is outstanding. In the event that the Treasury Index is no longer
published, a new index based upon comparable data and methodology will be
designated in accordance with the Agreement relating to the particular Series of
Securities. The Calculation Agent's determination of the Treasury Index, and its
calculation of the rates of interest for the applicable classes for the related
Interest Accrual Period, shall (in the absence of manifest error) be final and
binding.
 
PRIME RATE
 
     Unless otherwise specified in the related Prospectus Supplement, on the
Prime Rate Determination Date (as such term is defined in the related Prospectus
Supplement) for each class of Securities of a Series as to which the applicable
interest rate is determined by reference to an index denominated as the Prime
Rate, the Calculation Agent will ascertain the Prime Rate for the related
Interest Accrual Period. Unless otherwise specified in the related Prospectus
Supplement, the Prime Rate for an Interest Accrual Period will be the "Prime
Rate" as published in the "Money Rates" section of The Wall Street Journal (or
if not so published, the "Prime Rate" as published in a newspaper of general
circulation selected by the Calculation Agent in its
 
                                       53
<PAGE>   55
 
sole discretion) on the related Prime Rate Determination Date. If a prime rate
range is given, then the average of such range will be used. In the event that
the Prime Rate is no longer published, a new index based upon comparable data
and methodology will be designated in accordance with the Agreement relating to
the particular Series of Securities. The Calculation Agent's determination of
the Prime Rate and its calculation of the rates of interest for the related
Interest Accrual Period shall (in the absence of manifest error) be final and
binding.
 
BOOK-ENTRY REGISTRATION OF SECURITIES
 
     As described in the related Prospectus Supplement, if not issued in fully
registered form, each class of Securities will be registered as book-entry
certificates (the "Book-Entry Securities"). Persons acquiring beneficial
ownership interests in the Securities ("Security Owners") will hold their
Securities through The Depository Trust Company ("DTC") in the United States, or
CEDEL Bank, societe anonyme ("CEDEL") or the Euroclear System ("Euroclear") in
Europe if they are participants ("Participants") of such systems, or indirectly
through organizations that are Participants in such systems. The Book-Entry
Securities will be issued in one or more certificates which equal the aggregate
principal balance of the Securities and will initially be registered in the name
of Cede & Co., the nominee of DTC. CEDEL and Euroclear will hold omnibus
positions on behalf of their Participants through customers' securities accounts
in CEDEL's and Euroclear's names on the books of their respective depositaries
which in turn will hold such positions in customers' securities accounts in the
depositaries' names on the books of DTC. Citibank, N.A., will act as depositary
for CEDEL and The Chase Manhattan Bank will act as depositary for Euroclear (in
such capacities, individually the "Relevant Depositary" and collectively the
"European Depositaries"). Except as described below, no person acquiring a
Book-Entry Security (each, a "beneficial owner") will be entitled to receive a
physical certificate representing such Security (a "Definitive Security").
Unless and until Definitive Securities are issued, it is anticipated that the
only "Securityholders" of the Securities will be Cede & Co., as nominee of DTC.
Security Owners are only permitted to exercise their rights indirectly through
Participants and DTC.
 
     The beneficial owner's ownership of a Book-Entry Security will be recorded
on the records of the brokerage firm, bank, thrift institution or other
financial intermediary (each, a "Financial Intermediary") that maintains the
beneficial owner's account for such purpose. In turn, the Financial
Intermediary's ownership of such Book-Entry Security will be recorded on the
records of DTC (or of a participating firm that acts as agent for the Financial
Intermediary, whose interest will in turn be recorded on the records of DTC, if
the beneficial owner's Financial Intermediary is not a DTC Participant, and on
the records of CEDEL or Euroclear, as appropriate).
 
     Security Owners will receive all distributions of principal of, and
interest on, the Securities from the Trustee through DTC and DTC participants.
While the Securities are outstanding (except under the circumstances described
below), under the rules, regulations and procedures creating and affecting DTC
and its operations (the "Rules"), DTC is required to make book-entry transfers
among Participants on whose behalf it acts with respect to the Securities and is
required to receive and transmit distributions of principal of, and interest on,
the Securities. Participants and indirect participants with whom Security Owners
have accounts with respect to Securities are similarly required to make
book-entry transfers and receive and transmit such distributions on behalf of
their respective Security Owners. Accordingly, although Security Owners will not
possess certificates, the Rules provide a mechanism by which Security Owners
will receive distributions and will be able to transfer their interest.
 
     Security Owners will not receive or be entitled to receive certificates
representing their respective interests in the Securities, except under the
limited circumstances described below. Unless and until Definitive Securities
are issued, Security Owners who are not Participants may transfer ownership of
Securities only through Participants and indirect participants by instructing
such Participants and indirect participants to transfer Securities, by
book-entry transfer, through DTC for the account of the purchasers of such
Securities, which account is maintained with their respective Participants.
Under the Rules and in accordance with DTC's normal procedures, transfers of
ownership of Securities will be executed through DTC and the accounts of the
respective Participants at DTC will be debited and credited. Similarly, the
Participants and
 
                                       54
<PAGE>   56
 
indirect participants will make debits or credits, as the case may be, on their
records on behalf of the selling and purchasing Security Owners.
 
     Because of time zone differences, credits of securities received in CEDEL
or Euroclear as a result of a transaction with a Participant will be made during
subsequent securities settlement processing and dated the business day following
the DTC settlement date. Such credits or any transactions in such securities
settled during such processing will be reported to the relevant Euroclear or
CEDEL Participants on such business day. Cash received in CEDEL or Euroclear as
a result of sales of securities by or through a CEDEL Participant (as defined
herein) or Euroclear Participant (as defined herein) to a DTC Participant will
be received with value on the DTC settlement date but will be available in the
relevant CEDEL or Euroclear cash account only as of the business day following
settlement in DTC.
 
     Transfers between Participants will occur in accordance with the Rules.
Transfers between CEDEL Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
     Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through CEDEL
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance with DTC rules on behalf of the relevant European international
clearing system by the Relevant Depositary; however, such cross-market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in such system in accordance
with its rules and procedures and within its established deadlines (European
time). The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to the
Relevant Depositary to take action to effect final settlement on its behalf by
delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same day funds settlement applicable to
DTC. CEDEL Participants and Euroclear Participants may not deliver instructions
directly to the European Depositaries.
 
     DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, 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 pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934. DTC is owned by a number of its direct Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc.
 
     CEDEL is a duly licensed bank organized as a "societe anonyme" (limited
company) under the laws of Luxembourg. CEDEL holds securities for its
participating organizations ("CEDEL Participants") and facilitates the clearance
and settlement of securities transactions between CEDEL Participants through
electronic book-entry changes in accounts of CEDEL Participants, thereby
eliminating the need for physical movement of certificates. Transactions may be
settled in CEDEL in any of 37 currencies, including United States dollars. CEDEL
provides to its CEDEL Participants, among other things, services for
safekeeping, administration, clearance and settlement of internationally traded
securities and securities lending and borrowing. CEDEL interfaces with domestic
markets in several countries. As a licensed bank, CEDEL is subject to regulation
by the Luxembourg Monetary Institute. CEDEL Participants are recognized
financial institutions around the world, including underwriters, securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations. Indirect access to CEDEL is also available to others, such
as banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a CEDEL Participant, either directly or indirectly.
 
     Euroclear was created in 1968 to hold securities for its participants
("Euroclear Participants") and to clear and settle transactions between
Euroclear Participants through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled in any of 32 currencies, including United
States dollars. Euroclear includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements for cross-market transfers with DTC
described above. Euroclear is operated by the Brussels, Belgium office of
 
                                       55
<PAGE>   57
 
Morgan Guaranty Trust Company of New York ("Morgan" and in such capacity, the
"Euroclear Operator"), under contract with Euroclear Clearance Systems S.C., a
Belgian cooperative corporation (the "Belgian Cooperative"). All operations are
conducted by Morgan, and all Euroclear securities clearance accounts and
Euroclear cash accounts are accounts with the Euroclear Operator, not the
Belgian Cooperative. The Belgian Cooperative establishes policy for Euroclear on
behalf of Euroclear Participants. Euroclear Participants include banks
(including central banks), securities brokers and dealers and other professional
financial intermediaries. Indirect access to Euroclear is also available to
other firms that clear through or maintain a custodial relationship with a
Euroclear Participant, either directly or indirectly.
 
     Morgan is the Belgian branch of a New York banking corporation which is a
member bank of the Federal Reserve System. As such, it is regulated and examined
by the Board of Governors of the Federal Reserve System and the New York State
Banking Department, as well as the Belgian Banking Commission.
 
     Securities clearance accounts and cash accounts with Morgan are governed by
the Terms and Conditions Governing Use of Euroclear and the related Operating
Procedures of the Euroclear System and applicable Belgian law (collectively, the
"Terms and Conditions"). The Terms and Conditions govern transfers of securities
and cash within Euroclear, withdrawals of securities and cash from Euroclear,
and receipts of payments with respect to securities in Euroclear. All securities
in Euroclear are held on a fungible basis without attribution of specific
certificates to specific securities clearance accounts. The Euroclear Operator
acts under the Terms and Conditions only on behalf of Euroclear Participants,
and has no record of or relationship with persons holding through Euroclear
Participants.
 
     Under a book-entry format, beneficial owners of the Book-Entry Securities
may experience some delay in their receipt of payments, since such payments will
be forwarded by the Trustee to Cede & Co., as nominee of DTC. Distributions with
respect to Securities held through CEDEL or Euroclear will be credited to the
cash accounts of CEDEL Participants or Euroclear Participants in accordance with
the relevant system's rules and procedures, to the extent received by the
Relevant Depositary. Such distributions will be subject to tax reporting in
accordance with relevant United States tax laws and regulations. See "Federal
Income Tax Consequences -- Tax Treatment of Foreign Investors" and "-- Tax
Consequences to Holders of the Notes -- Backup Withholding." Because DTC can
only act on behalf of Financial Intermediaries, the ability of a beneficial
owner to pledge Book-Entry Securities to persons or entities that do not
participate in the Depository system, may be limited due to the lack of physical
certificates for such Book-Entry Securities. In addition, issuance of the
Book-Entry Securities in book-entry form may reduce the liquidity of such
Securities in the secondary market since certain potential investors may be
unwilling to purchase Securities for which they cannot obtain physical
certificates.
 
     Monthly and annual reports on the Trust Fund will be provided to Cede &
Co., as nominee of DTC, and may be made available by Cede & Co. to beneficial
owners upon request, in accordance with the rules, regulations and procedures
creating and affecting the Depository, and to the Financial Intermediaries to
whose DTC accounts the Book-Entry Securities of such beneficial owners are
credited.
 
     DTC has advised the Trustee that, unless and until Definitive Securities
are issued, DTC will take any action permitted to be taken by the holders of the
Book-Entry Securities under the applicable Agreement only at the direction of
one or more Financial Intermediaries to whose DTC accounts the Book-Entry
Securities are credited, to the extent that such actions are taken on behalf of
Financial Intermediaries whose holdings include such Book-Entry Securities.
CEDEL or the Euroclear Operator, as the case may be, will take any other action
permitted to be taken by a Securityholder under the Agreement on behalf of a
CEDEL Participant or Euroclear Participant only in accordance with its relevant
rules and procedures and subject to the ability of the Relevant Depositary to
effect such actions on its behalf through DTC. DTC may take actions, at the
direction of the related Participants, with respect to some Securities which
conflict with actions taken with respect to other Securities.
 
     Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Trustee will be required to notify all beneficial
owners of the occurrence of such event and the availability through DTC of
Definitive Securities. Upon surrender by DTC of the global certificate or
certificates representing the Book-Entry Securities and instructions for
re-registration, the Trustee will issue Definitive Securities, and
 
                                       56
<PAGE>   58
 
thereafter the Trustee will recognize the holders of such Definitive Securities
as Securityholders under the applicable Agreement.
 
     Although DTC, CEDEL and Euroclear have agreed to the foregoing procedures
in order to facilitate transfers of Securities among participants of DTC, CEDEL
and Euroclear, they are under no obligation to perform or continue to perform
such procedures and such procedures may be discontinued at any time.
 
     None of the Master Servicer, the Depositor or the Trustee will have any
responsibility for any aspect of the records relating to or payments made on
account of beneficial ownership interests of the Book-Entry Securities held by
Cede & Co., as nominee of DTC, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
                               CREDIT ENHANCEMENT
 
GENERAL
 
     Credit enhancement may be provided with respect to one or more classes of a
Series of Securities or with respect to the related Trust Fund Assets. Credit
enhancement may be in the form of a limited financial guaranty policy issued by
an entity named in the related Prospectus Supplement, the subordination of one
or more classes of the Securities of such Series, the establishment of one or
more Reserve Accounts, the use of a cross-collateralization feature, use of a
mortgage pool insurance policy, FHA Insurance, VA Guarantee, bankruptcy bond,
special hazard insurance policy, surety bond, letter of credit, guaranteed
investment contract, overcollateralization, interest rate swap agreement,
interest rate cap agreement or another method of credit enhancement contemplated
herein and described in the related Prospectus Supplement, or any combination of
the foregoing. Unless otherwise specified in the related Prospectus Supplement,
credit enhancement will not provide protection against all risks of loss and
will not guarantee repayment of the entire principal balance of the Securities
and interest thereon. If losses occur which exceed the amount covered by credit
enhancement or which are not covered by the credit enhancement, Securityholders
will bear their allocable share of any deficiencies.
 
SUBORDINATION
 
     If so specified in the related Prospectus Supplement, protection afforded
to holders of one or more classes of Securities of a Series by means of the
subordination feature may be accomplished by the preferential right of holders
of one or more other classes of such Series (the "Senior Securities") to
distributions in respect of scheduled principal, Principal Prepayments, interest
or any combination thereof that otherwise would have been payable to holders of
one or more classes of subordinate Securities (the "Subordinated Securities")
under the circumstances and to the extent specified in the related Prospectus
Supplement. Protection may also be afforded to the holders of Senior Securities
of a Series by: (i) reducing the ownership interest (if applicable) of the
related Subordinated Securities; (ii) a combination of the immediately preceding
sentence and clause (i) above; or (iii) as otherwise described in the related
Prospectus Supplement. If so specified in the related Prospectus Supplement,
delays in receipt of scheduled payments on the Loans and losses on defaulted
Loans may be borne first by the various classes of Subordinated Securities and
thereafter by the various classes of Senior Securities, in each case under the
circumstances and subject to the limitations specified in such Prospectus
Supplement. The aggregate distributions in respect of delinquent payments on the
Loans over the lives of the Securities or at any time, the aggregate losses in
respect of defaulted Loans which must be borne by the Subordinated Securities by
virtue of subordination and the amount of the distributions otherwise
distributable to the Subordinated Securityholders that will be distributable to
Senior Securityholders on any Distribution Date may be limited as specified in
the related Prospectus Supplement. If aggregate distributions in respect of
delinquent payments on the Loans or aggregate losses in respect of such Loans
were to exceed an amount specified in the related Prospectus Supplement, holders
of Senior Securities would experience losses on the Securities.
 
     In addition to or in lieu of the foregoing, if so specified in the related
Prospectus Supplement, all or any portion of distributions otherwise payable to
holders of Subordinated Securities on any Distribution Date may
 
                                       57
<PAGE>   59
 
instead be deposited into one or more Reserve Accounts established with the
Trustee or distributed to holders of Senior Securities. Such deposits may be
made on each Distribution Date, for specified periods or until the balance in
the Reserve Account has reached a specified amount and, following payments from
the Reserve Account to holders of Senior Securities or otherwise, thereafter to
the extent necessary to restore the balance in the Reserve Account to required
levels, in each case as specified in the related Prospectus Supplement. Amounts
on deposit in the Reserve Account may be released to the holders of certain
classes of Securities at the times and under the circumstances specified in such
Prospectus Supplement.
 
     If specified in the related Prospectus Supplement, various classes of
Senior Securities and Subordinated Securities may themselves be subordinate in
their right to receive certain distributions to other classes of Senior and
Subordinated Securities, respectively, through a cross-collateralization
mechanism or otherwise.
 
     As between classes of Senior Securities and as between classes of
Subordinated Securities, distributions may be allocated among such classes (i)
in the order of their scheduled final distribution dates, (ii) in accordance
with a schedule or formula, (iii) in relation to the occurrence of events, or
(iv) otherwise, in each case as specified in the related Prospectus Supplement.
As between classes of Subordinated Securities, payments to holders of Senior
Securities on account of delinquencies or losses and payments to any Reserve
Account will be allocated as specified in the related Prospectus Supplement.
 
LETTER OF CREDIT
 
     The letter of credit, if any, with respect to a Series of Securities will
be issued by the bank or financial institution specified in the related
Prospectus Supplement (the "L/C Bank"). Under the letter of credit, the L/C Bank
will be obligated to honor drawings thereunder in an aggregate fixed dollar
amount, net of unreimbursed payments thereunder, equal to the percentage
specified in the related Prospectus Supplement of the aggregate principal
balance of the Loans on the related Cut-off Date or of one or more Classes of
Securities (the "L/C Percentage"). If so specified in the related Prospectus
Supplement, the letter of credit may permit drawings in the event of losses not
covered by insurance policies or other credit support, such as losses arising
from damage not covered by standard hazard insurance policies, losses resulting
from the bankruptcy of a borrower and the application of certain provisions of
the federal Bankruptcy Code, or losses resulting from denial of insurance
coverage due to misrepresentations in connection with the origination of a Loan.
The amount available under the letter of credit will, in all cases, be reduced
to the extent of the unreimbursed payments thereunder. The obligations of the
L/C Bank under the letter of credit for each Series of Securities will expire at
the earlier of the date specified in the related Prospectus Supplement or the
termination of the Trust Fund. See "The Agreements -- Termination; Optional
Termination." A copy of the letter of credit for a Series, if any, will be filed
with the Commission as an exhibit to a Current Report on Form 8-K to be filed
within 15 days of issuance of the Securities of the related Series.
 
INSURANCE POLICIES, SURETY BONDS AND GUARANTIES
 
     If so provided in the Prospectus Supplement for a Series of Securities,
deficiencies in amounts otherwise payable on such Securities or certain classes
thereof will be covered by insurance policies and/or surety bonds provided by
one or more insurance companies or sureties. Such instruments may cover, with
respect to one or more classes of Securities of the related Series, timely
distributions of interest and/or full distributions of principal on the basis of
a schedule of principal distributions set forth in or determined in the manner
specified in the related Prospectus Supplement. In addition, if specified in the
related Prospectus Supplement, a Trust Fund may also include bankruptcy bonds,
special hazard insurance policies, other insurance or guaranties for the purpose
of (i) maintaining timely payments or providing additional protection against
losses on the assets included in such Trust Fund, (ii) paying administrative
expenses or (iii) establishing a minimum reinvestment rate on the payments made
in respect of such assets or principal payment rate on such assets. Such
arrangements may include agreements under which Securityholders are entitled to
receive amounts deposited in various accounts held by the Trustee upon the terms
specified in such Prospectus Supplement. A copy of any such instrument for a
Series will be filed with the Commission as an exhibit to a Current Report on
Form 8-K to be filed with the Commission within 15 days of issuance of the
Securities of the related Series.

OVER-COLLATERALIZATION
 
     If so provided in the Prospectus Supplement for a Series of Securities, a
portion of the interest payment on each Loan may be applied as an additional
distribution in respect of principal to reduce the principal balance of a
certain class or classes of Securities and, thus, accelerate the rate of payment
of principal on such class or classes of Securities.
 
RESERVE ACCOUNTS
 
     If specified in the related Prospectus Supplement, credit support with
respect to a Series of Securities will be provided by the establishment and
maintenance with the Trustee for such Series of Securities, in trust, of one or
more Reserve Accounts for such Series. The related Prospectus Supplement will
specify whether or not any such Reserve Accounts will be included in the Trust
Fund for such Series.
 
     The Reserve Account for a Series will be funded (i) by the deposit therein
of cash, United States Treasury securities, instruments evidencing ownership of
principal or interest payments thereon, letters of credit, demand notes,
certificates of deposit or a combination thereof in the aggregate amount
specified in the related Prospectus Supplement, (ii) by the deposit therein from
time to time of certain amounts, as specified in the related Prospectus
Supplement to which the Subordinate Securityholders, if any, would otherwise be
entitled or (iii) in such other manner as may be specified in the related
Prospectus Supplement.
 
     Any amounts on deposit in the Reserve Account and the proceeds of any other
instrument upon maturity will be held in cash or will be invested in "Permitted
Investments" which may include (i) obligations of the United States or any
agency thereof, provided such obligations are backed by the full faith and
credit of the United States; (ii) general obligations of or obligations
guaranteed by any state of the United States or the District of Columbia
receiving the highest long-term debt rating of each Rating Agency rating the
related Series of Securities, or such lower rating as will not result in the
downgrading or withdrawal of the ratings then assigned to such Securities by
each such Rating Agency; (iii) commercial or finance company paper which is then
receiving the highest commercial or finance company paper rating of each such
Rating Agency, or such lower rating as will not result in the downgrading or
withdrawal of the ratings then assigned to such Securities by each such Rating
Agency; (iv) certificates of deposit, demand or time deposits, or bankers'
acceptances issued by any depository institution or trust company incorporated
under the laws of the United States or of any state thereof and subject to
supervision and examination by federal and/or state banking authorities,
provided that the commercial paper and/or long term unsecured debt obligations
of such depository institution or trust company (or in the case of the principal
depository institution in a holding company system, the commercial paper or
long-term unsecured debt obligations of such holding company, but only if
Moody's Investors Service, Inc. ("Moody's") is not a Rating Agency) are then
rated in one of the two highest long-term and the highest short-term ratings of
each such Rating Agency for such securities, or such lower ratings as will not
result in the downgrading or withdrawal of the rating then assigned to such
Securities by any such rating Agency; (iv) demand or time deposits or
certificates of deposit issued by any bank or trust company or savings
institution to the extent that such deposits are fully insured by the FDIC; (v)
guaranteed reinvestment agreements issued by any bank, insurance company or
other corporation containing, at the time of the issuance of such agreements,
such terms and conditions as will not result in the downgrading or withdrawal of
the rating then assigned to such Securities by any such Rating Agency; (vi)
repurchase obligations with respect to any security described in clauses (i) and
(ii) above, in either case entered into with a depository institution or trust
company (acting as principal) described in clause (iv) above; (vii) securities
(other than stripped bonds, stripped coupons or instruments sold at a purchase
price in excess of 115% of the face amount thereof) bearing interest or sold at
a discount and issued by any corporation incorporated under the laws of the
United States or any state thereof which, at the time of such investment, have
one of the two highest ratings of each Rating Agency (except that if the Rating
Agency is Moody's, such rating shall be the highest commercial paper rating of
Moody's for any such securities), or such lower rating as will not result in the
downgrading or withdrawal of the rating then assigned to such Securities by any
such Rating Agency; (viii) interests in any money market fund which at the date
of acquisition of the interests in such fund and throughout the time such
interests are held in such fund has the highest applicable rating by each such
Rating Agency or such lower rating as will not result in the downgrading or
withdrawal of the ratings then assigned to such Securities by
 
                                       59
<PAGE>   61
 
each such Rating Agency; and (ix) short term investment funds sponsored by any
trust company or national banking association incorporated under the laws of the
United States or any state thereof which on the date of acquisition has been
rated by each such Rating Agency in their respective highest applicable rating
category or such lower rating as will not result in the downgrading or
withdrawal of the ratings then assigned to such Securities by each such Rating
Agency; provided, that no such instrument shall be a Permitted Investment if
such instrument evidences the right to receive interest only payments with
respect to the obligations underlying such instrument. If a letter of credit is
deposited with the Trustee, such letter of credit will be irrevocable. Unless
otherwise specified in the related Prospectus Supplement, any instrument
deposited therein will name the Trustee, in its capacity as trustee for the
holders of the Securities, as beneficiary and will be issued by an entity
acceptable to each Rating Agency that rates the Securities of the related
Series. Additional information with respect to such instruments deposited in the
Reserve Accounts will be set forth in the related Prospectus Supplement.
 
     Any amounts so deposited and payments on instruments so deposited will be
available for withdrawal from the Reserve Account for distribution to the
holders of Securities of the related Series for the purposes, in the manner and
at the times specified in the related Prospectus Supplement.
 
POOL INSURANCE POLICIES
 
     If specified in the related Prospectus Supplement, a separate pool
insurance policy ("Pool Insurance Policy") will be obtained for the Pool and
issued by the insurer (the "Pool Insurer") named in such Prospectus Supplement.
 
     Each Pool Insurance Policy will, subject to the limitations described
below, cover loss by reason of default in payment on Loans in the Pool in an
amount equal to a percentage specified in such Prospectus Supplement of the
aggregate principal balance of such Loans on the Cut-off Date which are not
covered as to their entire outstanding principal balances by Primary Mortgage
Insurance Policies. As more fully described below, the Master Servicer will
present claims thereunder to the Pool Insurer on behalf of itself, the Trustee
and the holders of the Securities of the related Series. The Pool Insurance
Policies, however, are not blanket policies against loss, since claims
thereunder may only be made respecting particular defaulted Loans and only upon
satisfaction of certain conditions precedent described below. Unless otherwise
specified in the related Prospectus Supplement, the Pool Insurance Policies will
not cover losses due to a failure to pay or denial of a claim under a Primary
Mortgage Insurance Policy.
 
     Unless otherwise specified in the related Prospectus Supplement, the Pool
Insurance Policy will provide that no claims may be validly presented unless (i)
any required Primary Mortgage Insurance Policy is in effect for the defaulted
Loan and a claim thereunder has been submitted and settled; (ii) hazard
insurance on the related Property has been kept in force and real estate taxes
and other protection and preservation expenses have been paid; (iii) if there
has been physical loss or damage to the Property, it has been restored to its
physical condition (reasonable wear and tear excepted) at the time of issuance
of the policy; and (iv) the insured has acquired good and merchantable title to
the Property free and clear of liens except certain permitted encumbrances. Upon
satisfaction of these conditions, the Pool Insurer will have the option either
(a) to purchase the property securing the defaulted Loan at a price equal to the
principal balance thereof plus accrued and unpaid interest at the Loan Rate to
the date of such purchase and certain expenses incurred by the Master Servicer
on behalf of the Trustee and Securityholders, or (b) to pay the amount by which
the sum of the principal balance of the defaulted Loan plus accrued and unpaid
interest at the Loan Rate to the date of payment of the claim and the
aforementioned expenses exceeds the proceeds received from an approved sale of
the Property, in either case net of certain amounts paid or assumed to have been
paid under the related Primary Mortgage Insurance Policy. If any Property
securing a defaulted Loan is damaged and proceeds, if any, from the related
hazard insurance policy or the applicable special hazard insurance policy are
insufficient to restore the damaged Property to a condition sufficient to permit
recovery under the Pool Insurance Policy, the Master Servicer will not be
required to expend its own funds to restore the damaged Property unless it
determines that (i) such restoration will increase the proceeds to
Securityholders on liquidation of the Loan after reimbursement of the Master
Servicer for its expenses and (ii) such expenses will be recoverable by it
 
                                       60
<PAGE>   62
 
through proceeds of the sale of the Property or proceeds of the related Pool
Insurance Policy or any related Primary Mortgage Insurance Policy.
 
     Unless otherwise specified in the related Prospectus Supplement, the Pool
Insurance Policy will not insure (and many Primary Mortgage Insurance Policies
do not insure) against loss sustained by reason of a default arising from, among
other things, (i) fraud or negligence in the origination or servicing of a Loan,
including misrepresentation by the borrower, the originator or persons involved
in the origination thereof, or (ii) failure to construct a Property in
accordance with plans and specifications. A failure of coverage attributable to
one of the foregoing events might result in a breach of the related Seller's or
Originator's representations described above, and, in such events might give
rise to an obligation on the part of such Seller or Originator to repurchase the
defaulted Loan if the breach cannot be cured by such Seller or Originator. No
Pool Insurance Policy will cover (and many Primary Mortgage Insurance Policies
do not cover) a claim in respect of a defaulted Loan occurring when the servicer
of such Loan, at the time of default or thereafter, was not approved by the
applicable insurer.
 
     Unless otherwise specified in the related Prospectus Supplement, the
original amount of coverage under each Pool Insurance Policy will be reduced
over the life of the related Securities by the aggregate dollar amount of claims
paid less the aggregate of the net amounts realized by the Pool Insurer upon
disposition of all foreclosed properties. The amount of claims paid will include
certain expenses incurred by the Master Servicer as well as accrued interest on
delinquent Loans to the date of payment of the claim, unless otherwise specified
in the related Prospectus Supplement. Accordingly, if aggregate net claims paid
under any Pool Insurance Policy reach the original policy limit, coverage under
that Pool Insurance Policy will be exhausted and any further losses will be
borne by the related Securityholders.
 
CROSS-COLLATERALIZATION
 
     If specified in the related Prospectus Supplement, the beneficial ownership
of separate groups of assets included in a Trust Fund may be evidenced by
separate classes of the related Series of Securities. In such case, credit
support may be provided by a cross-collateralization feature which requires that
distributions be made with respect to Securities evidencing a beneficial
ownership interest in, or secured by, one or more asset groups within the same
Trust Fund prior to distributions to Subordinated Securities evidencing a
beneficial ownership interest in, or secured by, one or more other asset groups
within such Trust Fund. Cross-collateralization may be provided by (i) the
allocation of certain excess amounts generated by one or more asset groups
within the same Trust Fund to one or more other asset groups within the same
Trust Fund or (ii) the allocation of losses with respect to one or more asset
groups to one or more other asset groups within the same Trust Fund. Such excess
amounts will be applied and/or such losses will be allocated to the class or
classes of Subordinated Securities of the related Series then outstanding having
the lowest rating assigned by any Rating Agency or the lowest payment priority,
in each case to the extent and in the manner more specifically described in the
related Prospectus Supplement. The Prospectus Supplement for a Series which
includes a cross-collateralization feature will describe the manner and
conditions for applying such cross-collateralization feature.
 
     If specified in the related Prospectus Supplement, the coverage provided by
one or more forms of credit support described in this Prospectus may apply
concurrently to two or more related Trust Funds. If applicable, the related
Prospectus Supplement will identify the Trust Funds to which such credit support
relates and the manner of determining the amount of the coverage provided
thereby and of the application of such coverage to the identified Trust Funds.
 
OTHER INSURANCE, SURETY BONDS, GUARANTIES, LETTERS OF CREDIT AND SIMILAR
INSTRUMENTS OR AGREEMENTS
 
     If specified in the related Prospectus Supplement, a Trust Fund may also
include bankruptcy bonds, special hazard insurance policies, other insurance,
guaranties, or similar arrangements for the purpose of (i) maintaining timely
payments or providing additional protection against losses on the assets
included in such Trust Fund, (ii) paying administrative expenses or (iii)
establishing a minimum reinvestment rate on the payments made in respect of such
assets or principal payment rate on such assets. Such arrangements may
 
                                       61
<PAGE>   63
 
include agreements under which Securityholders are entitled to receive amounts
deposited in various accounts held by the Trustee upon the terms specified in
such Prospectus Supplement. If specified in the related Prospectus Supplement,
the Trust Fund may also include interest rate swap agreements or interest rate
cap agreements. An interest rate swap agreement involves an agreement between
two parties under which one party makes to the other party periodic payments
based on a fixed rate of interest and receives in return periodic payments based
on a variable rate of interest, which rates of interest are calculated on the
basis of a specified notional amount of principal for a specified period of time
as will be described in the related Prospectus Supplement. An interest rate cap
agreement involves an agreement between two parties in which one party agrees to
make payments to the other party when a designated market interest rate goes
above a designated level on predetermined dates or during a specified time
period as will be described in the related Prospectus Supplement.
 
                      YIELD AND PREPAYMENT CONSIDERATIONS
 
     The yields to maturity and weighted average lives of the Securities will be
affected primarily by the amount and timing of principal payments received on or
in respect of the Trust Fund Assets included in the related Trust Fund. The
original terms to maturity of the Loans in a given Pool will vary depending upon
the type of Loans included therein. Each Prospectus Supplement will contain
information with respect to the type and maturities of the Loans in the related
Pool. The related Prospectus Supplement will specify the circumstances, if any,
under which the related Loans will be subject to prepayment penalties. The
prepayment experience on the Loans in a Pool will affect the weighted average
life of the related Series of Securities.
 
     The rate of prepayment on the Loans cannot be predicted. Home equity loans
and home improvement contracts have been originated in significant volume only
during the past few years and the Depositor is not aware of any publicly
available studies or statistics on the rate of prepayment of such loans.
Generally, home equity loans and home improvement contracts are not viewed by
borrowers as permanent financing. Accordingly, the Loans may experience a higher
rate of prepayment than traditional first mortgage loans. On the other hand,
because home equity loans such as the Revolving Credit Line Loans generally are
not fully amortizing, the absence of voluntary borrower prepayments could cause
rates of principal payments lower than, or similar to, those of traditional
fully-amortizing first mortgage loans. The prepayment experience of the related
Trust Fund may be affected by a wide variety of factors, including general
economic conditions, prevailing interest rate levels, the availability of
alternative financing, homeowner mobility and the frequency and amount of any
future draws on any Revolving Credit Line Loans. Other factors that might be
expected to affect the prepayment rate of a pool of home equity mortgage loans
or home improvement contracts include the amounts of, and interest rates on, the
underlying senior mortgage loans, and the use of first mortgage loans as
long-term financing for home purchase and subordinate mortgage loans as
shorter-term financing for a variety of purposes, including home improvement,
education expenses and purchases of consumer durables such as automobiles.
Accordingly, the Loans may experience a higher rate of prepayment than
traditional fixed-rate mortgage loans. In addition, any future limitations on
the right of borrowers to deduct interest payments on home equity loans for
federal income tax purposes may further increase the rate of prepayments of the
Loans. The enforcement of a "due-on-sale" provision (as described below) will
have the same effect as a prepayment of the related Loan. See "Certain Legal
Aspects of the Loans -- Due-on-Sale Clauses." The yield to an investor who
purchases Securities in the secondary market at a price other than par will vary
from the anticipated yield if the rate of prepayment on the Loans is actually
different than the rate anticipated by such investor at the time such Securities
were purchased.
 
     Collections on Revolving Credit Line Loans may vary because, among other
things, borrowers may (i) make payments during any month as low as the minimum
monthly payment for such month or, during the interest-only period for certain
Revolving Credit Line Loans and, in more limited circumstances, Closed-End
Loans, with respect to which an interest-only payment option has been selected,
the interest and the fees and charges for such month or (ii) make payments as
high as the entire outstanding principal balance plus accrued interest and the
fees and charges thereon. It is possible that borrowers may fail to make the
required periodic payments. In addition, collections on the Loans may vary due
to seasonal purchasing and the payment habits of borrowers.
 
                                       62
<PAGE>   64
 
     Unless otherwise specified in the related Prospectus Supplement, all
conventional Loans will contain due-on-sale provisions permitting the mortgagee
to accelerate the maturity of the loan upon sale or certain transfers by the
borrower of the related Property. Loans insured by the FHA, and Single Family
Loans partially guaranteed by the VA, are assumable with the consent of the FHA
and the VA, respectively. Thus, the rate of prepayments on such Loans may be
lower than that of conventional Loans bearing comparable interest rates. Unless
otherwise specified in the related Prospectus Supplement, the Master Servicer
generally will enforce any due-on-sale or due-on-encumbrance clause, to the
extent it has knowledge of the conveyance or further encumbrance or the proposed
conveyance or proposed further encumbrance of the Property and reasonably
believes that it is entitled to do so under applicable law; provided, however,
that the Master Servicer will not take any enforcement action that would impair
or threaten to impair any recovery under any related insurance policy. See "The
Agreements -- Collection Procedures" and "Certain Legal Aspects of the Loans"
for a description of certain provisions of each Agreement and certain legal
developments that may affect the prepayment experience on the Loans.
 
     The rate of prepayments with respect to conventional mortgage loans has
fluctuated significantly in recent years. In general, if prevailing rates fall
significantly below the Loan Rates borne by the Loans, such Loans are more
likely to be subject to higher prepayment rates than if prevailing interest
rates remain at or above such Loan Rates. Conversely, if prevailing interest
rates rise appreciably above the Loan Rates borne by the Loans, such Loans are
more likely to experience a lower prepayment rate than if prevailing rates
remain at or below such Loan Rates. However, there can be no assurance that such
will be the case.
 
     When a full prepayment is made on a Loan, the borrower is charged interest
on the principal amount of the Loan so prepaid only for the number of days in
the month actually elapsed up to the date of the prepayment, rather than for a
full month. Unless otherwise provided in the related Prospectus Supplement, the
effect of prepayments in full will be to reduce the amount of interest passed
through or paid in the following month to holders of Securities because interest
on the principal amount of any Loan so prepaid generally will be paid only to
the date of prepayment. Partial prepayments in a given month may be applied to
the outstanding principal balances of the Loans so prepaid on the first day of
the month of receipt or the month following receipt. In the latter case, partial
prepayments will not reduce the amount of interest passed through or paid in
such month. Unless otherwise specified in the related Prospectus Supplement,
neither full nor partial prepayments will be passed through or paid until the
month following receipt.
 
     Even assuming that the Properties provide adequate security for the Loans,
substantial delays could be encountered in connection with the liquidation of
defaulted Loans and corresponding delays in the receipt of related proceeds by
Securityholders could occur. An action to foreclose on a Property securing a
Loan is regulated by state statutes and rules and is subject to many of the
delays and expenses of other lawsuits if defenses or counterclaims are
interposed, sometimes requiring several years to complete. Furthermore, in some
states an action to obtain a deficiency judgment is not permitted following a
nonjudicial sale of a property. In the event of a default by a borrower, these
restrictions among other things, may impede the ability of the Master Servicer
to foreclose on or sell the Property or to obtain liquidation proceeds
sufficient to repay all amounts due on the related Loan. In addition, the Master
Servicer will be entitled to deduct from related liquidation proceeds all
expenses reasonably incurred in attempting to recover amounts due on defaulted
Loans and not yet repaid, including payments to senior lienholders, legal fees
and costs of legal action, real estate taxes and maintenance and preservation
expenses.
 
     Liquidation expenses with respect to defaulted mortgage loans do not vary
directly with the outstanding principal balance of the loan at the time of
default. Therefore, assuming that a servicer took the same steps in realizing
upon a defaulted mortgage loan having a small remaining principal balance as it
would in the case of a defaulted mortgage loan having a large remaining
principal balance, the amount realized after expenses of liquidation would be
smaller as a percentage of the remaining principal balance of the small mortgage
loan than would be the case with the other defaulted mortgage loan having a
large remaining principal balance.
 
     Applicable state laws generally regulate interest rates and other charges,
require certain disclosures, and require licensing of certain originators and
servicers of Loans. In addition, most have other laws, public policy and general
principles of equity relating to the protection of consumers, unfair and
deceptive practices and
 
                                       63
<PAGE>   65
 
practices which may apply to the origination, servicing and collection of the
Loans. Depending on the provisions of the applicable law and the specific facts
and circumstances involved, violations of these laws, policies and principles
may limit the ability of the Master Servicer to collect all or part of the
principal of or interest on the Loans, may entitle the borrower to a refund of
amounts previously paid and, in addition, could subject the Master Servicer to
damages and administrative sanctions.
 
     If the rate at which interest is passed through or paid to the holders of
Securities of a Series is calculated on a Loan-by-Loan basis, disproportionate
principal prepayments among Loans with different Loan Rates will affect the
yield on such Securities. In most cases, the effective yield to Securityholders
will be lower than the yield otherwise produced by the applicable Pass-Through
Rate or interest rate and purchase price, because while interest will accrue on
each Loan from the first day of the month (unless otherwise specified in the
related Prospectus Supplement), the distribution of such interest will not be
made earlier than the month following the month of accrual.
 
     Under certain circumstances, the Master Servicer, the holders of the
residual interests in a REMIC or any person specified in the related Prospectus
Supplement may have the option to purchase the assets of a Trust Fund thereby
effecting earlier retirement of the related Series of Securities. See "The
Agreements -- Termination; Optional Termination."
 
     The relative contribution of the various factors affecting prepayment may
also vary from time to time. There can be no assurance as to the rate of payment
of principal of the Trust Fund Assets at any time or over the lives of the
Securities.
 
     The Prospectus Supplement relating to a Series of Securities will discuss
in greater detail the effect of the rate and timing of principal payments
(including prepayments), delinquencies and losses on the yield, weighted average
lives and maturities of such Securities.
 
                                 THE AGREEMENTS
 
     Set forth below is a description of the material provisions of each
Agreement which are not described elsewhere in this Prospectus. The description
is subject to, and qualified in its entirety by reference to, the provisions of
each Agreement. Where particular provisions or terms used in the Agreements are
referred to, such provisions or terms are as specified in the Agreements.
 
ASSIGNMENT OF THE TRUST FUND ASSETS
 
     Assignment of the Loans.  At the time of issuance of the Securities of a
Series, and except as otherwise specified in the related Prospectus Supplement,
the Depositor will cause the Loans comprising the related Trust Fund to be
assigned to the Trustee, without recourse, together with all principal and
interest received by or on behalf of the Depositor on or with respect to such
Loans after the Cut-off Date, other than principal and interest due on or before
the Cut-off Date and other than any Retained Interest specified in the related
Prospectus Supplement. The Trustee will, concurrently with such assignment,
deliver such Securities to the Depositor in exchange for the Loans. Each Loan
will be identified in a schedule appearing as an exhibit to the related
Agreement. Such schedule will include information as to the outstanding
principal balance of each Loan after application of payments due on or before
the Cut-off Date, as well as information regarding the Loan Rate or APR, the
maturity of the Loan, the Loan-to-Value Ratios or Combined Loan-to-Value Ratios,
as applicable, at origination and certain other information.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Agreement will require that, within the time period specified therein, the
Depositor will also deliver or cause to be delivered to the Trustee (or to the
custodian hereinafter referred to) as to each Mortgage Loan or Home Equity Loan,
among other things, (i) the mortgage note or contract endorsed without recourse
in blank or to the order of the Trustee, (ii) the mortgage, deed of trust or
similar instrument (a "Mortgage") with evidence of recording indicated thereon
(except for any Mortgage not returned from the public recording office, in which
case the Depositor will deliver or cause to be delivered a copy of such Mortgage
together with a certificate that the original of such Mortgage was delivered to
such recording office), (iii) an assignment of the Mortgage to the Trustee,
which
 
                                       64
<PAGE>   66
 
assignment will be in recordable form in the case of a Mortgage assignment, and
(iv) such other security documents, including those relating to any senior
interests in the Property, as may be specified in the related Prospectus
Supplement or the related Agreement. Unless otherwise specified in the related
Prospectus Supplement, the Depositor will promptly cause the assignments of the
related Loans to be recorded in the appropriate public office for real property
records, except in states in which, in the opinion of counsel acceptable to the
Trustee, such recording is not required to protect the Trustee's interest in
such Loans against the claim of any subsequent transferee or any successor to or
creditor of the Depositor or the Originators of such Loans.
 
     With respect to any Loans that are Cooperative Loans, the Depositor will
cause to be delivered to the Trustee the related original cooperative note
endorsed without recourse in blank or to the order of the Trustee, the original
security agreement, the proprietary lease or occupancy agreement, the
recognition agreement, an executed financing agreement and the relevant stock
certificate, related blank stock powers and any other document specified in the
related Prospectus Supplement. The Depositor will cause to be filed in the
appropriate office an assignment and a financing statement evidencing the
Trustee's security interest in each Cooperative Loan.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Depositor will as to each Contract, deliver or cause to be delivered to the
Trustee the original Contract and copies of documents and instruments related to
each Contract and, other than in the case of unsecured Contracts, the security
interest in the Property securing such Contract. In order to give notice of the
right, title and interest of Securityholders to the Contracts, the Depositor
will cause a UCC-1 financing statement to be executed by the Depositor or the
Seller identifying the Trustee as the secured party and identifying all
Contracts as collateral. Unless otherwise specified in the related Prospectus
Supplement, the Contracts will not be stamped or otherwise marked to reflect
their assignment to the Trustee. Therefore, if, through negligence, fraud or
otherwise, a subsequent purchaser were able to take physical possession of the
Contracts without notice of such assignment, the interest of Securityholders in
the Contracts could be defeated. See "Certain Legal Aspects of the Loans -- The
Contracts."
 
     The Trustee (or the custodian hereinafter referred to) will review such
Loan documents within the time period specified in the related Prospectus
Supplement after receipt thereof, and the Trustee will hold such documents in
trust for the benefit of the related Securityholders. Unless otherwise specified
in the related Prospectus Supplement, if any such document is found to be
missing or defective in any material respect, the Trustee (or such custodian)
will notify the Master Servicer and the Depositor, and the Master Servicer will
notify the related Seller or Originator.
 
     If such Seller or Originator cannot cure the omission or defect within the
time period specified in the related Prospectus Supplement after receipt of such
notice, such Seller or Originator will be obligated to either (i) purchase the
related Loan from the Trust Fund at the Purchase Price or (ii) if so specified
in the related Prospectus Supplement, remove such Loan from the Trust Fund and
substitute in its place one or more other Loans that meets certain requirements
set forth therein. There can be no assurance that a Seller or Originator will
fulfill this purchase or substitution obligation. Although the Master Servicer
may be obligated to enforce such obligation to the extent described above under
"The Trust Fund -- Representations by Sellers or Originators; Repurchases,"
neither the Master Servicer nor the Depositor will be obligated to purchase or
replace such Loan if the Seller or Originator defaults on its obligation, unless
such breach also constitutes a breach of the representations or warranties of
the Master Servicer or the Depositor, as the case may be. Unless otherwise
specified in the related Prospectus Supplement, this obligation to cure,
purchase or substitute constitutes the sole remedy available to the
Securityholders or the Trustee for omission of, or a material defect in, a
constituent document.
 
     The Trustee will be authorized to appoint a custodian pursuant to a
custodial agreement to maintain possession of and, if applicable, to review the
documents relating to the Loans as agent of the Trustee.
 
     The Master Servicer will make certain representations and warranties
regarding its authority to enter into, and its ability to perform its
obligations under, the Agreement. Upon a breach of any such representation of
the Master Servicer which materially and adversely affects the interests of the
Securityholders in a Loan, the
 
                                       65
<PAGE>   67
 
Master Servicer will be obligated either to cure the breach in all material
respects or to purchase (at the Purchase Price) or if so specified in the
related Prospectus Supplement, replace the Loan. Unless otherwise specified in
the related Prospectus Supplement, this obligation to cure, purchase or
substitute constitutes the sole remedy available to the Securityholders or the
Trustee for such a breach of representation by the Master Servicer.
 
     Notwithstanding the foregoing provisions, with respect to a Trust Fund for
which a REMIC election is to be made, no purchase or substitution of a Loan will
be made if such purchase or substitution would result in a prohibited
transaction tax under the Code.
 
NO RECOURSE TO SELLERS, ORIGINATORS, DEPOSITOR OR MASTER SERVICER
 
     As described above under "-- Assignment of the Trust Fund Assets," the
Depositor will cause the Loans comprising the related Trust Fund to be assigned
to the Trustee, without recourse. However, each Seller or Originator will be
obligated to repurchase or substitute for any Loan as to which certain
representations and warranties are breached or for failure to deliver certain
documents relating to the Loans as described above under "-- Assignment of the
Trust Fund Assets" and under "The Trust Fund -- Representations by Sellers or
Originators; Repurchases." These obligations to purchase or substitute
constitute the sole remedy available to the Securityholders or the Trustee for a
breach of any such representation or failure to deliver a constituent document.
 
PAYMENTS ON LOANS; DEPOSITS TO SECURITY ACCOUNT
 
     The Master Servicer will establish and maintain or cause to be established
and maintained with respect to the related Trust Fund a separate account or
accounts for the collection of payments on the related Trust Fund Assets in the
Trust Fund (the "Security Account") which, unless otherwise specified in the
related Prospectus Supplement, must be either (i) maintained with a depository
institution the debt obligations of which (or in the case of a depository
institution that is the principal subsidiary of a holding company, the
obligations of which) are rated in one of the two highest rating categories by
the Rating Agency or Rating Agencies that rated one or more classes of the
related Series of Securities, (ii) an account or accounts the deposits in which
are fully insured by either the Bank Insurance Fund (the "BIF") of the FDIC or
the Savings Association Insurance Fund (as successor to the Federal Savings and
Loan Insurance Corporation ("SAIF")), (iii) an account or accounts the deposits
in which are insured by the BIF or SAIF (to the limits established by the FDIC),
and the uninsured deposits in which are otherwise secured such that, as
evidenced by an opinion of counsel, the Securityholders have a claim with
respect to the funds in the Security Account or a perfected first priority
security interest against any collateral securing such funds that is superior to
the claims of any other depositors or general creditors of the depository
institution with which the Security Account is maintained, or (iv) an account or
accounts otherwise acceptable to each Rating Agency. The collateral eligible to
secure amounts in the Security Account is limited to Permitted Investments. A
Security Account may be maintained as an interest bearing account or the funds
held therein may be invested pending each succeeding Distribution Date in
Permitted Investments. Unless otherwise specified in the related Prospectus
Supplement, the Master Servicer or its designee will be entitled to receive any
such interest or other income earned on funds in the Security Account as
additional compensation and will be obligated to deposit in the Security Account
the amount of any loss immediately as realized. The Security Account may be
maintained with the Master Servicer or with a depository institution that is an
affiliate of the Master Servicer, provided it meets the standards set forth
above.
 
     The Master Servicer will deposit or cause to be deposited in the Security
Account for each Trust Fund, to the extent applicable and unless otherwise
specified in the related Prospectus Supplement and provided in the Agreement,
the following payments and collections received or advances made by or on behalf
of it subsequent to the Cut-off Date (other than payments due on or before the
Cut-off Date and exclusive of any amounts representing Retained Interest):
 
          (i) all payments on account of principal, including Principal
     Prepayments and, if specified in the related Prospectus Supplement, any
     applicable prepayment penalties, on the Loans;
 
                                       66
<PAGE>   68
 
          (ii) all payments on account of interest on the Loans, net of
     applicable servicing compensation;
 
          (iii) all proceeds (net of unreimbursed payments of property taxes,
     insurance premiums and similar items ("Insured Expenses") incurred, and
     unreimbursed Advances made, by the Master Servicer, if any) of the hazard
     insurance policies and any Primary Mortgage Insurance Policies, to the
     extent such proceeds are not applied to the restoration of the property or
     released to the Mortgagor in accordance with the Master Servicer's normal
     servicing procedures (collectively, "Insurance Proceeds") and all other
     cash amounts (net of unreimbursed expenses incurred in connection with
     liquidation or foreclosure ("Liquidation Expenses") and unreimbursed
     Advances made, by the Master Servicer, if any) received and retained in
     connection with the liquidation of defaulted Loans, by foreclosure or
     otherwise ("Liquidation Proceeds"), together with any net proceeds received
     on a monthly basis with respect to any properties acquired on behalf of the
     Securityholders by foreclosure or deed in lieu of foreclosure;
 
          (iv) all proceeds of any Loan or property in respect thereof purchased
     by the Master Servicer, the Depositor or any Seller or Originators as
     described under "The Trust Funds -- Representations by Sellers or
     Originators; Repurchases" or under "-- Assignment of Trust Fund Assets"
     above and all proceeds of any Loan repurchased as described under
     "-- Termination; Optional Termination" below;
 
          (v) all payments required to be deposited in the Security Account with
     respect to any deductible clause in any blanket insurance policy described
     under "-- Hazard Insurance" below;
 
          (vi) any amount required to be deposited by the Master Servicer in
     connection with losses realized on investments for the benefit of the
     Master Servicer of funds held in the Security Account and, to the extent
     specified in the related Prospectus Supplement, any payments required to be
     made by the Master Servicer in connection with prepayment interest
     shortfalls; and
 
          (vii) all other amounts required to be deposited in the Security
     Account pursuant to the Agreement.
 
     The Master Servicer (or the Depositor, as applicable) may from time to time
direct the institution that maintains the Security Account to withdraw funds
from the Security Account for the following purposes:
 
          (i) to pay to the Master Servicer the servicing fees described in the
     related Prospectus Supplement, the master servicing fees (subject to
     reduction) and, as additional servicing compensation, earnings on or
     investment income with respect to funds in the amounts in the Security
     Account credited thereto;
 
          (ii) to reimburse the Master Servicer for Advances, such right of
     reimbursement with respect to any Loan being limited to amounts received
     that represent late recoveries of payments of principal and/or interest on
     such Loan (or Insurance Proceeds or Liquidation Proceeds with respect
     thereto) with respect to which such Advance was made;
 
          (iii) to reimburse the Master Servicer for any Advances previously
     made which the Master Servicer has determined to be nonrecoverable;
 
          (iv) to reimburse the Master Servicer from Insurance Proceeds for
     expenses incurred by the Master Servicer and covered by the related
     insurance policies;
 
          (v) to reimburse the Master Servicer for unpaid master servicing fees
     and unreimbursed out-of-pocket costs and expenses incurred by the Master
     Servicer in the performance of its servicing obligations, such right of
     reimbursement being limited to amounts received representing late
     recoveries of the payments for which such advances were made;
 
          (vi) to pay to the Master Servicer, with respect to each Loan or
     property acquired in respect thereof that has been purchased by the Master
     Servicer pursuant to the Agreement, all amounts received thereon and not
     taken into account in determining the principal balance of such repurchased
     Loan;
 
          (vii) to reimburse the Master Servicer or the Depositor for expenses
     incurred and reimbursable pursuant to the Agreement;
 
                                       67
<PAGE>   69
 
          (viii) to withdraw any amount deposited in the Security Account and
     not required to be deposited therein; and
 
          (ix) to clear and terminate the Security Account upon termination of
     the Agreement.
 
     In addition, unless otherwise specified in the related Prospectus
Supplement, on or prior to the business day immediately preceding each
Distribution Date, the Master Servicer shall withdraw from the Security Account
the amount of Available Funds, to the extent on deposit, for deposit in an
account maintained by the Trustee for the related Series of Securities.
 
PRE-FUNDING ACCOUNT
 
     If so provided in the related Prospectus Supplement, the Master Servicer
will establish and maintain a Pre-Funding Account, in the name of the related
Trustee on behalf of the related Securityholders, into which the Depositor will
deposit cash from the proceeds of the issuance of the related Securities in an
amount equal to the Pre-Funded Amount on the related Closing Date. The
Pre-Funded Amount will not exceed 25% of the initial aggregate principal amount
of the Certificates and/or Notes of the related Series. The Pre-Funding Account
will be maintained with the Trustee for the related Series of Securities and is
designed solely to hold funds to be applied by such Trustee during the Funding
Period to pay to the Depositor the purchase price for Subsequent Loans. Monies
on deposit in the Pre-Funding Account will not be available to cover losses on
or in respect of the related Loans. The Pre-Funded Amount will be used by the
related Trustee to purchase Subsequent Loans from the Depositor from time to
time during the Funding Period. Each Subsequent Loan that is purchased by the
related Trustee will be required to be underwritten in accordance with the
eligibility criteria set forth in the related Agreement and in the related
Prospectus Supplement. Such eligibility criteria will be determined in
consultation with the applicable Rating Agency or Rating Agencies prior to the
issuance of the related Series of Securities and are designed to ensure that if
such Subsequent Loans were included as part of the initial Loans, the credit
quality of such assets would be consistent with the initial rating or ratings of
the Securities of such Series. The Depositor will certify to the Trustee that
all conditions precedent to the transfer of the Subsequent Loans to the Trust
Fund, including, among other things, the satisfaction of the related eligibility
criteria, have been satisfied. It is a condition precedent to the transfer of
any Subsequent Loans to the Trust Fund that the applicable Rating Agency or
Rating Agencies, after receiving prior notice of the proposed transfer of the
Subsequent Loans to the Trust Fund, will not have advised the Depositor or the
related Trustee that the conveyance of the Subsequent Loans to the Trust Fund
will result in a qualification, modification or withdrawal of their current
rating of any Securities of such Series. Upon the purchase by the Trustee of a
Subsequent Loan, such Subsequent Loan will be included in the related Trust Fund
Assets. The Funding Period, if any, for a Trust Fund will begin on the related
Closing Date and will end on the date specified in the related Prospectus
Supplement, which in no event will be later than the date that is three months
after the related Closing Date. Monies on deposit in the Pre-Funding Account may
be invested in Permitted Investments under the circumstances and in the manner
described in the related Agreement. See the "Index of Defined Terms" on page 119
of this Prospectus for the location of the defined term "Permitted Investments."
Earnings on investment of funds in the Pre-Funding Account will be deposited
into the related Security Account or such other trust account as is specified in
the related Prospectus Supplement and losses will be charged against the funds
on deposit in the Pre-Funding Account. Any amounts remaining in the Pre-Funding
Account at the end of the Funding Period will be distributed to the related
Securityholders in the manner and priority specified in the related Prospectus
Supplement, as a prepayment of principal of the related Securities. The
Depositor will include information regarding the additional Subsequent Loans in
a Current Report on Form 8-K, to be filed after the end of the Funding Period,
to the extent that such information, individually or in the aggregate, is
material.
 
     In addition, if so provided in the related Prospectus Supplement, the
Master Servicer will establish and maintain, in the name of the Trustee on
behalf of the related Securityholders, an account (the "Capitalized Interest
Account") into which the Depositor will deposit cash from the proceeds of the
issuance of the related Securities in such amount as is necessary to cover
shortfalls in interest on the related Series of Securities that may arise as a
result of a portion of the assets of the Trust Fund not being invested in Loans
and the utilization of the Pre-Funding Account as described above. The
Capitalized Interest Account shall be maintained with
 
                                       68
<PAGE>   70
 
the Trustee for the related Series of Securities and is designed solely to cover
the above-mentioned interest shortfalls. Monies on deposit in the Capitalized
Interest Account will not be available to cover losses on or in respect of the
related Loans. Amounts on deposit in the Capitalized Interest Account will be
distributed to Securityholders on the Distribution Dates occurring in the
Funding Period to cover any shortfalls in interest on the related Series of
Securities as described in the related Prospectus Supplement. To the extent that
the entire amount on deposit in the Capitalized Interest Account has not been
applied to cover shortfalls in interest on the related Series of Securities by
the end of the Funding Period, any amounts remaining in the Capitalized Interest
Account will be paid to the Depositor.
 
SUB-SERVICING BY SELLERS
 
     Each Seller of a Loan or any other servicing entity may act as the
Sub-Servicer for such Loan pursuant to an agreement (each, a "Sub-Servicing
Agreement"), which will not contain any terms inconsistent with the related
Agreement. While each Sub-Servicing Agreement will be a contract solely between
the Master Servicer and the Sub-Servicer, the Agreement pursuant to which a
Series of Securities is issued will provide that, if for any reason the Master
Servicer for such Series of Securities is no longer the Master Servicer of the
related Loans, the Trustee or any successor Master Servicer may assume the
Master Servicer's rights and obligations under such Sub-Servicing Agreement.
Notwithstanding any such subservicing arrangement, unless otherwise provided in
the related Prospectus Supplement, the Master Servicer will remain liable for
its servicing duties and obligations under the Master Servicing Agreement as if
the Master Servicer alone were servicing the Loans.
 
COLLECTION PROCEDURES
 
     The Master Servicer, directly or through one or more Sub-Servicers, will
make reasonable efforts to collect all payments called for under the Loans and
will, consistent with each Agreement and any Pool Insurance Policy, Primary
Mortgage Insurance Policy, FHA Insurance, VA Guaranty, bankruptcy bond or
alternative arrangements, follow such collection procedures as are customary
with respect to loans that are comparable to the Loans. Consistent with the
above, the Master Servicer may, in its discretion, unless otherwise specified in
the related Prospectus Supplement (i) waive any assumption fee, late payment or
other charge in connection with a Loan and (ii) to the extent not inconsistent
with the coverage of such Loan by a Pool Insurance Policy, Primary Mortgage
Insurance Policy, FHA Insurance, VA Guaranty, bankruptcy bond or alternative
arrangements, if applicable, arrange with a borrower a schedule for the
liquidation of delinquencies running for no more than 125 days after the
applicable due date for each payment. Each Agreement and the related Prospectus
Supplement will specify the time period during which payments received by the
Master Servicer may be commingled with the Master Servicer's own funds prior to
each Distribution Date. To the extent the Master Servicer is obligated to make
or cause to be made Advances, such obligation will remain during any period of
such an arrangement.
 
     Unless otherwise specified in the related Prospectus Supplement, in any
case in which property securing a Loan has been, or is about to be, conveyed by
the mortgagor or obligor, the Master Servicer will, to the extent it has
knowledge of such conveyance or proposed conveyance, exercise or cause to be
exercised its rights to accelerate the maturity of such Loan under any
due-on-sale clause applicable thereto, but only if the exercise of such rights
is permitted by applicable law and will not impair or threaten to impair any
recovery under any Primary Mortgage Insurance Policy. If these conditions are
not met or if the Master Servicer reasonably believes it is unable under
applicable law to enforce such due-on-sale clause or if such Loan is a mortgage
loan insured by the FHA or partially guaranteed by the VA, the Master Servicer
will enter into or cause to be entered into an assumption and modification
agreement with the person to whom such property has been or is about to be
conveyed, pursuant to which such person becomes liable for repayment of the Loan
and, to the extent permitted by applicable law, the mortgagor remains liable
thereon. Any fee collected by or on behalf of the Master Servicer for entering
into an assumption agreement will be retained by or on behalf of the Master
Servicer as additional servicing compensation. See "Certain Legal Aspects of the
Loans -- Due-on-Sale Clauses." In connection with any such assumption, the terms
of the related Loan may not be changed.
 
                                       69
<PAGE>   71
 
     With respect to Cooperative Loans, any prospective purchaser will generally
have to obtain the approval of the board of directors of the relevant
Cooperative before purchasing the shares and acquiring rights under the related
proprietary lease or occupancy agreement. See "Certain Legal Aspects of the
Loans." This approval is usually based on the purchaser's income and net worth
and numerous other factors. Although the Cooperative's approval is unlikely to
be unreasonably withheld or delayed, the necessity of acquiring such approval
could limit the number of potential purchasers for those shares and otherwise
limit the Trust Fund's ability to sell and realize the value of those shares.
 
     In general, a "tenant-stockholder" (as defined in Code Section 216(b)(2))
of a corporation that qualifies as a "cooperative housing corporation" within
the meaning of Code Section 216(b)(1) is allowed a deduction for amounts paid or
accrued within his taxable year to the corporation representing his
proportionate share of certain interest expenses and certain real estate taxes
allowable as a deduction under Code Section 216(a) to the corporation under Code
Sections 163 and 164. In order for a corporation to qualify under Code Section
216(b)(1) for its taxable year in which such items are allowable as a deduction
to the corporation, such Section requires, among other things, that at least 80%
of the gross income of the corporation be derived from its tenant-stockholders
(as defined in Code Section 216(b)(2)). By virtue of this requirement, the
status of a corporation for purposes of Code Section 216(b)(1) must be
determined on a year-to-year basis. Consequently, there can be no assurance that
Cooperatives relating to the Cooperative Loans will qualify under such Section
for any particular year. In the event that such a Cooperative fails to qualify
for one or more years, the value of the collateral securing any related
Cooperative Loans could be significantly impaired because no deduction would be
allowable to tenant-stockholders under Code Section 216(a) with respect to those
years. In view of the significance of the tax benefits accorded
tenant-stockholders of a corporation that qualifies under Code Section
216(b)(1), the likelihood that such a failure would be permitted to continue
over a period of years appears remote.
 
HAZARD INSURANCE
 
     Except as otherwise specified in the related Prospectus Supplement, the
Master Servicer will require the mortgagor or obligor on each Loan to maintain a
hazard insurance policy providing for no less than the coverage of the standard
form of fire insurance policy with extended coverage customary for the type of
Property in the state in which such Property is located. Such coverage will be
in an amount that is at least equal to the lesser of (i) the maximum insurable
value of the improvements securing such Loan or (ii) the greater of (y) the
outstanding principal balance of the Loan and (z) an amount such that the
proceeds of such policy shall be sufficient to prevent the mortgagor and/or the
mortgagee from becoming a co-insurer. All amounts collected by the Master
Servicer under any hazard policy (except for amounts to be applied to the
restoration or repair of the Property or released to the mortgagor or obligor in
accordance with the Master Servicer's normal servicing procedures) will be
deposited in the related Security Account. In the event that the Master Servicer
maintains a blanket policy insuring against hazard losses on all the Loans
comprising part of a Trust Fund, it will conclusively be deemed to have
satisfied its obligation relating to the maintenance of hazard insurance. Such
blanket policy may contain a deductible clause, in which case the Master
Servicer will be required to deposit from its own funds into the related
Security Account the amounts which would have been deposited therein but for
such clause.
 
     In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements securing a Loan by fire,
lightning, explosion, smoke, windstorm and hail, riot, strike and civil
commotion, subject to the conditions and exclusions particularized in each
policy. Although the policies relating to the Loans may have been underwritten
by different insurers under different state laws in accordance with different
applicable forms and therefore may not contain identical terms and conditions,
the basic terms thereof are dictated by respective state laws, and most such
policies typically do not cover any physical damage resulting from the
following: war, revolution, governmental actions, floods and other water-
related causes, earth movement (including earthquakes, landslides and mud
flows), nuclear reactions, wet or dry rot, vermin, rodents, insects or domestic
animals, theft and, in certain cases, vandalism. The foregoing list is merely
indicative of certain kinds of uninsured risks and is not intended to be all
inclusive. If the Property
 
                                       70
<PAGE>   72
 
securing a Loan is located in a federally designated special flood area at the
time of origination, the Master Servicer will require the mortgagor or obligor
to obtain and maintain flood insurance.
 
     The hazard insurance policies covering properties securing the Loans
typically contain a clause which in effect requires the insured at all time to
carry insurance of a specified percentage of a specified percentage (generally
80% to 90%) of the full replacement value of the insured property in order to
recover the full amount of any partial loss. If the insured's coverage falls
below this specified percentage, then the insurer's liability in the event of
partial loss will not exceed the larger of (i) the actual cash value (generally
defined as replacement cost at the time and place of loss, less physical
depreciation) of the improvements damaged or destroyed or (ii) such proportion
of the loss as the amount of insurance carried bears to the specified percentage
of the full replacement cost of such improvements. Since the amount of hazard
insurance the Master Servicer may cause to be maintained on the improvements
securing the Loans declines as the principal balances owing thereon decrease,
and since improved real estate generally has appreciated in value over time in
the past, the effect of this requirement in the event of partial loss may be
that hazard insurance proceeds will be insufficient to restore fully the damaged
property. If specified in the related Prospectus Supplement, a special hazard
insurance policy will be obtained to insure against certain of the uninsured
risks described above. See "Credit Enhancement."
 
     Unless otherwise specified in the related Prospectus Supplement, the Master
Servicer will not require that a standard hazard or flood insurance policy be
maintained on the cooperative dwelling relating to any Cooperative Loan.
Generally, the Cooperative itself is responsible for maintenance of hazard
insurance for the property owned by the Cooperative and the tenant-stockholders
of that Cooperative do not maintain individual hazard insurance policies. To the
extent, however, that a Cooperative and the related borrower on a Cooperative
Loan do not maintain such insurance or do not maintain adequate coverage or any
insurance proceeds are not applied to the restoration of damaged property, any
damage to such borrower's cooperative dwelling or such Cooperative's building
could significantly reduce the value of the collateral securing such Cooperative
Loan to the extent not covered by other credit support.
 
     If the Property securing a defaulted Loan is damaged and proceeds, if any,
from the related hazard insurance policy are insufficient to restore the damaged
Property, the Master Servicer is not required to expend its own funds to restore
the damaged Property unless it determines (i) that such restoration will
increase the proceeds to Securityholders on liquidation of the Loan after
reimbursement of the Master Servicer for its expenses and (ii) that such
expenses will be recoverable by it from related Insurance Proceeds or
Liquidation Proceeds.
 
     If recovery on a defaulted Loan under any related Insurance Policy is not
available for the reasons set forth in the preceding paragraph, or if the
defaulted Loan is not covered by an Insurance Policy, the Master Servicer will
be obligated to follow or cause to be followed such normal practices and
procedures as it deems necessary or advisable to realize upon the defaulted
Loan. If the proceeds of any liquidation of the Property securing the defaulted
Loan are less than the principal balance of such Loan plus interest accrued
thereon that is payable to Securityholders, the Trust Fund will realize a loss
in the amount of such difference plus the aggregate of expenses incurred by the
Master Servicer in connection with such proceedings and which are reimbursable
under the Agreement. In the unlikely event that any such proceedings result in a
total recovery which is, after reimbursement to the Master Servicer of its
expenses, in excess of the principal balance of such Loan plus interest accrued
thereon that is payable to Securityholders, the Master Servicer will be entitled
to withdraw or retain from the Security Account amounts representing its normal
servicing compensation with respect to such Loan and, unless otherwise specified
in the related Prospectus Supplement, amounts representing the balance of such
excess, exclusive of any amount required by law to be forwarded to the related
borrower, as additional servicing compensation.
 
     Unless otherwise specified in the related Prospectus Supplement, if the
Master Servicer or its designee recovers Insurance Proceeds which, when added to
any related Liquidation Proceeds and after deduction of certain expenses
reimbursable to the Master Servicer, exceed the principal balance of such Loan
plus interest accrued thereon that is payable to Securityholders, the Master
Servicer will be entitled to withdraw or retain from the Security Account
amounts representing its normal servicing compensation with respect to such
Loan.
 
                                       71
<PAGE>   73
 
In the event that the Master Servicer has expended its own funds to restore the
damaged Property and such funds have not been reimbursed under the related
hazard insurance policy, it will be entitled to withdraw from the Security
Account out of related Liquidation Proceeds or Insurance Proceeds an amount
equal to such expenses incurred by it, in which event the Trust Fund may realize
a loss up to the amount so charged. Since Insurance Proceeds cannot exceed
deficiency claims and certain expenses incurred by the Master Servicer, no such
payment or recovery will result in a recovery to the Trust Fund which exceeds
the principal balance of the defaulted Loan together with accrued interest
thereon. See "Credit Enhancement."
 
     Unless otherwise specified in the related Prospectus Supplement or the
related Agreement, the proceeds from any liquidation of a Loan will be applied
in the following order of priority: first, to reimburse the Master Servicer for
any unreimbursed expenses incurred by it to restore the related Property and any
unreimbursed servicing compensation payable to the Master Servicer with respect
to such Loan; second, to reimburse the Master Servicer for any unreimbursed
Advances with respect to such Loan; third, to accrued and unpaid interest (to
the extent no Advance has been made for such amount) on such Loan; and fourth,
as a recovery of principal of such Loan.
 
REALIZATION UPON DEFAULTED LOANS
 
     Primary Mortgage Insurance Policies.  If so specified in the related
Prospectus Supplement, the Master Servicer will maintain or cause to be
maintained, as the case may be, in full force and effect, a Primary Mortgage
Insurance Policy with regard to each Loan for which such coverage is required.
Primary Mortgage Insurance Policies reimburse certain losses sustained by reason
of defaults in payments by borrowers. Although the terms and conditions of
Primary Mortgage Insurance Policies differ, each Primary Mortgage Insurance
Policy will generally cover losses up to an amount equal to the excess of the
unpaid principal amount of a defaulted Loan (plus accrued and unpaid interest
thereon and certain approved expenses) over a specified percentage of the value
of the related Mortgaged Property. The Master Servicer will not cancel or refuse
to renew any such Primary Mortgage Insurance Policy in effect at the time of the
initial issuance of a Series of Securities that is required to be kept in force
under the applicable Agreement unless the replacement Primary Mortgage Insurance
Policy for such cancelled or nonrenewed policy is maintained with an insurer
whose claims-paying ability is sufficient to maintain the current rating of the
classes of Securities of such Series that have been rated.
 
     FHA Insurance; VA Guaranties.  Loans designated in the related Prospectus
Supplement as insured by the FHA will be insured by the FHA as authorized under
the United States Housing Act of 1937, as amended. In addition to the Title I
Program of the FHA, see "Certain Legal Aspects of the Loans -- The Title I
Program," certain Loans will be insured under various FHA programs including the
standard FHA 203(b) program to finance the acquisition of one- to four-family
housing units and the FHA 245 graduated payment mortgage program. These programs
generally limit the principal amount and interest rates of the mortgage loans
insured. Loans insured by FHA generally require a minimum down payment of
approximately 5% of the original principal amount of the loan. No FHA-insured
Loans relating to a Series may have an interest rate or original principal
amount exceeding the applicable FHA limits at the time of origination of such
loan.
 
     Loans designated in the related Prospectus Supplement as guaranteed by the
VA will be partially guaranteed by the VA under the Serviceman's Readjustment
Act of 1944, as amended (a "VA Guaranty"). The Serviceman's Readjustment Act of
1944, as amended, permits a veteran (or in certain instances the spouse of a
veteran) to obtain a mortgage loan guaranty by the VA covering mortgage
financing of the purchase of a one-to four-family dwelling unit at interest
rates permitted by the VA. The program has no mortgage loan limits, requires no
down payment from the purchaser and permits the guaranty of mortgage loans of up
to 30 years' duration. However, no Loan guaranteed by the VA will have an
original principal amount greater than five times the partial VA guaranty for
such Loan. The maximum guaranty that may be issued by the VA under a VA
guaranteed mortgage loan depends upon the original principal amount of the
mortgage loan, as further described in 38 United States Code Section 1803(a), as
amended.

SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES
 
     The principal servicing compensation to be paid to the Master Servicer in
respect of its master servicing activities for each Series of Securities will be
equal to the percentage per annum described in the related Prospectus Supplement
(which may vary under certain circumstances) of the outstanding principal
balance of each Loan, and such compensation will be retained by it from
collections of interest on such Loan in the related Trust Fund (the "Master
Servicing Fee"). Unless otherwise specified in the related Prospectus
Supplement, as compensation for its servicing duties, a Sub-Servicer or, if
there is no Sub-Servicer, the Master Servicer will be entitled to a monthly
servicing fee as described in the related Prospectus Supplement. In addition,
unless otherwise specified in the related Prospectus Supplement, the Master
Servicer or Sub-Servicer will retain all prepayment charges, assumption fees and
late payment charges, to the extent collected from borrowers, and any benefit
that may accrue as a result of the investment of funds in the applicable
Security Account (unless otherwise specified in the related Prospectus
Supplement).
 
     The Master Servicer will pay or cause to be paid certain ongoing expenses
associated with each Trust Fund and incurred by it in connection with its
responsibilities under the related Agreement, including, without limitation,
payment of any fee or other amount payable in respect of any credit enhancement
arrangements, payment of the fees and disbursements of the Trustee, any
custodian appointed by the Trustee, the certificate registrar and any paying
agent, and payment of expenses incurred in enforcing the obligations of
Sub-Servicers and Sellers. The Master Servicer will be entitled to reimbursement
of expenses incurred in enforcing the obligations of Sub-Servicers and Sellers
under certain limited circumstances.
 
EVIDENCE AS TO COMPLIANCE
 
     Each Agreement will provide that on or before a specified date in each
year, a firm of independent public accountants will furnish a statement to the
Trustee to the effect that, on the basis of the examination by such firm
conducted substantially in compliance with the Uniform Single Attestation
Program for Mortgage Bankers or the Audit Program for Mortgages serviced for
FHLMC, the servicing by or on behalf of the Master Servicer of mortgage loans or
private asset backed securities, or under pooling and servicing agreements
substantially similar to each other (including the related Agreement), was
conducted in compliance with such agreements except for any significant
exceptions or errors in records that, in the opinion of the firm, the Audit
Program for Mortgages serviced for FHLMC, or the Uniform Single Attestation
Program for Mortgage Bankers, it is required to report. In rendering its
statement such firm may rely, as to matters relating to the direct servicing of
Loans by Sub-Servicers, upon comparable statements for examinations conducted
substantially in compliance with the Uniform Single Attestation Program for
Mortgage Bankers or the Audit Program for Mortgages serviced for FHLMC (rendered
within one year of such statement) of firms of independent public accountants
with respect to the related Sub-Servicer.
 
     Each Agreement will also provide for delivery to the Trustee, on or before
a specified date in each year, of an annual statement signed by two officers of
the Master Servicer to the effect that the Master Servicer has fulfilled its
obligations under the Agreement throughout the preceding year.
 
     Copies of the annual accountants' statement and the statement of officers
of the Master Servicer may be obtained by Securityholders of the related Series
without charge upon written request to the Master Servicer at the address set
forth in the related Prospectus Supplement.
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER AND THE DEPOSITOR
 
     The Master Servicer under each Pooling and Servicing Agreement or Master
Servicing Agreement, as applicable, will be named in the related Prospectus
Supplement. Each Agreement will provide that the Master Servicer may not resign
from its obligations and duties under the Agreement except upon a determination
that its duties thereunder are no longer permissible under applicable law. The
Master Servicer may, however, be removed from its obligations and duties as set
forth in the Agreement. No such resignation will become effective until the
Trustee or a successor servicer has assumed the Master Servicer's obligations
and duties under the Agreement.
 
                                       73
<PAGE>   75
 
     Each Agreement will further provide that neither the Master Servicer, the
Depositor nor any director, officer, employee, or agent of the Master Servicer
or the Depositor will be under any liability to the related Trust Fund or
Securityholders for any action taken or for refraining from the taking of any
action in good faith pursuant to the Agreement, or for errors in judgment;
provided, however, that neither the Master Servicer, the Depositor nor any such
person will be protected against any liability which would otherwise be imposed
by reason of wilful misfeasance, bad faith or gross negligence in the
performance of duties thereunder or by reason of reckless disregard of
obligations and duties thereunder. Each Agreement will further provide that the
Master Servicer, the Depositor and any director, officer, employee or agent of
the Master Servicer or the Depositor will be entitled to indemnification by the
related Trust Fund and will be held harmless against any loss, liability or
expense incurred in connection with any legal action relating to the Agreement
or the Securities, other than any loss, liability or expense related to any
specific Loan or Loans (except any such loss, liability or expense otherwise
reimbursable pursuant to the Agreement) and any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties thereunder or by reason of reckless disregard of
obligations and duties thereunder. In addition, each Agreement will provide that
neither the Master Servicer nor the Depositor will be under any obligation to
appear in, prosecute or defend any legal action which is not incidental to its
respective responsibilities under the Agreement and which in its opinion may
involve it in any expense or liability. The Master Servicer or the Depositor
may, however, in its discretion undertake any such action which it may deem
necessary or desirable with respect to the Agreement and the rights and duties
of the parties thereto and the interests of the Securityholders thereunder. In
such event, the legal expenses and costs of such action and any liability
resulting therefrom will be expenses, costs and liabilities of the Trust Fund
and the Master Servicer or the Depositor, as the case may be, will be entitled
to be reimbursed therefor out of funds otherwise distributable to
Securityholders.
 
     Except as otherwise specified in the related Prospectus Supplement, any
person into which the Master Servicer may be merged or consolidated, or any
person resulting from any merger or consolidation to which the Master Servicer
is a party, or any person succeeding to the business of the Master Servicer,
will be the successor of the Master Servicer under each Agreement, provided that
such person is qualified to sell mortgage loans to, and service mortgage loans
on behalf of, FNMA or FHLMC and further provided that such merger, consolidation
or succession does not adversely affect the then current rating or ratings of
the class or classes of Securities of such Series that have been rated.
 
EVENTS OF DEFAULT; RIGHTS UPON EVENT OF DEFAULT
 
     Pooling and Servicing Agreement; Master Servicing Agreement.  Except as
otherwise specified in the related Prospectus Supplement, Events of Default
under each Agreement will consist of (i) any failure by the Master Servicer to
distribute or cause to be distributed to Securityholders of any class any
required payment (other than an Advance) which continues unremedied for five
days after the giving of written notice of such failure to the Master Servicer
by the Trustee or the Depositor, or to the Master Servicer, the Depositor and
the Trustee by the holders of Securities of such class evidencing not less than
25% of the total distributions allocated to such class ("Percentage Interests");
(ii) any failure by the Master Servicer to make an Advance as required under the
Agreement, unless cured as specified therein; (iii) any failure by the Master
Servicer duly to observe or perform in any material respect any of its other
covenants or agreements in the Agreement which continues unremedied for thirty
days after the giving of written notice of such failure to the Master Servicer
by the Trustee or the Depositor, or to the Master Servicer, the Depositor and
the Trustee by the holders of Securities of any class evidencing not less than
25% of the aggregate Percentage Interests constituting such class; and (iv)
certain events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceeding and certain actions by or on behalf of the
Master Servicer indicating its insolvency, reorganization or inability to pay
its obligations.
 
     If specified in the related Prospectus Supplement, the Agreement will
permit the Trustee to sell the Trust Fund Assets and the other assets of the
Trust Fund described under "Credit Enhancement" herein in the event that
payments in respect thereto are insufficient to make payments required in the
Agreement. The
 
                                       74
<PAGE>   76
 
assets of the Trust Fund will be sold only under the circumstances and in the
manner specified in the related Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, so long as
an Event of Default under an Agreement remains unremedied, the Depositor or the
Trustee may, and at the direction of holders of Securities of any class
evidencing not less than 25% of the aggregate Percentage Interests constituting
such class and under such other circumstances as may be specified in such
Agreement, the Trustee shall terminate all of the rights and obligations of the
Master Servicer under the Agreement relating to such Trust Fund and in and to
the related Trust Fund Assets, whereupon the Trustee will succeed to all of the
responsibilities, duties and liabilities of the Master Servicer under the
Agreement, including, if specified in the related Prospectus Supplement, the
obligation to make Advances, and will be entitled to similar compensation
arrangements. In the event that the Trustee is unwilling or unable so to act, it
may appoint, or petition a court of competent jurisdiction for the appointment
of, a mortgage loan servicing institution with a net worth of a least
$10,000,000 to act as successor to the Master Servicer under the Agreement.
Pending such appointment, the Trustee is obligated to act in such capacity. The
Trustee and any such successor may agree upon the servicing compensation to be
paid, which in no event may be greater than the compensation payable to the
Master Servicer under the Agreement.
 
     Unless otherwise specified in the related Prospectus Supplement, no
Securityholder, solely by virtue of such holder's status as a Securityholder,
will have any right under any Agreement to institute any proceeding with respect
to such Agreement, unless such holder previously has given to the Trustee
written notice of default and unless the holders of Securities of any class of
such Series evidencing not less than 25% of the aggregate Percentage Interests
constituting such class have made written request upon the Trustee to institute
such proceeding in its own name as Trustee thereunder and have offered to the
Trustee reasonable indemnity, and the Trustee for 60 days has neglected or
refused to institute any such proceeding.
 
     Indenture.  Except as otherwise specified in the related Prospectus
Supplement, Events of Default under the Indenture for each Series of Notes
include: (i) a default in the payment of any principal of or interest on any
Note of such Series which continues unremedied for five days after the giving of
written notice of such default is given as specified in the related Prospectus
Supplement; (ii) failure to perform in any material respect any other covenant
of the Depositor or the Trust Fund in the Indenture which continues for a period
of thirty (30) days after notice thereof is given in accordance with the
procedures described in the related Prospectus Supplement; (iii) certain events
of bankruptcy, insolvency, receivership or liquidation of the Depositor or the
Trust Fund; or (iv) any other Event of Default provided with respect to Notes of
that Series including but not limited to certain defaults on the part of the
issuer, if any, of a credit enhancement instrument supporting such Notes.
 
     If an Event of Default with respect to the Notes of any Series at the time
outstanding occurs and is continuing, either the Trustee or the holders of a
majority of the then aggregate outstanding amount of the Notes of such Series
may declare the principal amount (or, if the Notes of that Series have an
interest rate of 0%, such portion of the principal amount as may be specified in
the terms of that Series, as provided in the related Prospectus Supplement) of
all the Notes of such Series to be due and payable immediately. Such declaration
may, under certain circumstances, be rescinded and annulled by the holders of
more than 50% of the Percentage Interests of the Notes of such Series.
 
     If, following an Event of Default with respect to any Series of Notes, the
Notes of such Series have been declared to be due and payable, the Trustee may,
in its discretion, notwithstanding such acceleration, elect to maintain
possession of the collateral securing the Notes of such Series and to continue
to apply distributions on such collateral as if there had been no declaration of
acceleration if such collateral continues to provide sufficient funds for the
payment of principal of and interest on the Notes of such Series as they would
have become due if there had not been such a declaration. In addition, the
Trustee may not sell or otherwise liquidate the collateral securing the Notes of
a Series following an Event of Default, other than a default in the payment of
any principal or interest on any Note of such Series for five days or more,
unless (a) the holders of 100% of the Percentage Interests of the Notes of such
Series consent to such sale, (b) the proceeds of such sale or liquidation are
sufficient to pay in full the principal of and accrued interest, due and unpaid,
on the
 
                                       75
<PAGE>   77
 
outstanding Notes of such Series at the date of such sale or (c) the Trustee
determines that such collateral would not be sufficient on an ongoing basis to
make all payments on such Notes as such payments would have become due if such
Notes had not been declared due and payable, and the Trustee obtains the consent
of the holders of 66 2/3% of the Percentage Interests of the Notes of such
Series.
 
     In the event that the Trustee liquidates the collateral in connection with
an Event of Default involving a default for five days or more in the payment of
principal of or interest on the Notes of a Series, the Indenture provides that
the Trustee will have a prior lien on the proceeds of any such liquidation for
unpaid fees and expenses. As a result, upon the occurrence of such an Event of
Default, the amount available for distribution to the Noteholders would be less
than would otherwise be the case. However, the Trustee may not institute a
proceeding for the enforcement of its lien except in connection with a
proceeding for the enforcement of the lien of the Indenture for the benefit of
the Noteholders after the occurrence of such an Event of Default.
 
     Except as otherwise specified in the related Prospectus Supplement, in the
event the principal of the Notes of a Series is declared due and payable, as
described above, the holders of any such Notes issued at a discount from par may
be entitled to receive no more than an amount equal to the unpaid principal
amount thereof less the amount of such discount which is unamortized.
 
     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing with respect
to a Series of Notes, the Trustee shall be under no obligation to exercise any
of the rights or powers under the Indenture at the request or direction of any
of the holders of Notes of such Series, unless such holders offered to the
Trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities which might be incurred by it in complying with such request or
direction. Subject to such provisions for indemnification and certain
limitations contained in the Indenture, the holders of a majority of the then
aggregate outstanding amount of the Notes of such Series shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee with respect to the Notes of such Series, and the holders of a majority
of the then aggregate outstanding amount of the Notes of such Series may, in
certain cases, waive any default with respect thereto, except a default in the
payment of principal or interest or a default in respect of a covenant or
provision of the Indenture that cannot be modified without the waiver or consent
of all the holders of the outstanding Notes of such Series affected thereby.
 
AMENDMENT
 
     Except as otherwise specified in the related Prospectus Supplement, each
Agreement may be amended by the Depositor, the Master Servicer and the Trustee,
without the consent of any of the Securityholders, (i) to cure any ambiguity;
(ii) to correct or supplement any provision therein which may be defective or
inconsistent with any other provision therein; or (iii) to make any other
revisions with respect to matters or questions arising under the Agreement which
are not inconsistent with the provisions thereof, provided that such action will
not adversely affect in any material respect the interests of any
Securityholder. An amendment will be deemed not to adversely affect in any
material respect the interests of the Securityholders if the person requesting
such amendment obtains a letter from each Rating Agency requested to rate the
class or classes of Securities of such Series stating that such amendment will
not result in the downgrading or withdrawal of the respective ratings then
assigned to such Securities. In addition, to the extent provided in the related
Agreement, an Agreement may be amended without the consent of any of the
Securityholders, to change the manner in which the Security Account is
maintained, provided that any such change does not adversely affect the then
current rating on the class or classes of Securities of such Series that have
been rated. In addition, if a REMIC election is made with respect to a Trust
Fund, the related Agreement may be amended to modify, eliminate or add to any of
its provisions to such extent as may be necessary to maintain the qualification
of the related Trust Fund as a REMIC, provided that the Trustee has received an
opinion of counsel to the effect that such action is necessary or helpful to
maintain such qualification. Except as otherwise specified in the related
Prospectus Supplement, each Agreement may also be amended by the Depositor, the
Master Servicer and the Trustee with consent of holders of Securities of such
Series evidencing not less than 66% of the aggregate Percentage Interests of
each class affected thereby for the purpose of adding any provisions to or
changing in an manner or eliminating any of the provisions of the Agreement or
of
 
                                       76
<PAGE>   78
 
modifying in any manner the rights of the holders of the related Securities;
provided, however, that no such amendment may (i) reduce in any manner the
amount of or delay the timing of, payments received on Loans which are required
to be distributed on any Security without the consent of the holder of such
Security, or (ii) reduce the aforesaid percentage of Securities of any class the
holders of which are required to consent to any such amendment without the
consent of the holders of all Securities of such class covered by such Agreement
then outstanding. If a REMIC election is made with respect to a Trust Fund, the
Trustee will not be entitled to consent to an amendment to the related Agreement
without having first received an opinion of counsel to the effect that such
amendment will not cause such Trust Fund to fail to qualify as a REMIC.
 
TERMINATION; OPTIONAL TERMINATION
 
     Pooling and Servicing Agreement; Trust Agreement.  Unless otherwise
specified in the related Agreement, the obligations created by each Pooling and
Servicing Agreement and Trust Agreement for each Series of Securities will
terminate upon the payment to the related Securityholders of all amounts held in
the Security Account or by the Master Servicer and required to be paid to them
pursuant to such Agreement following the later of (i) the final payment of or
other liquidation of the last of the Trust Fund Assets subject thereto or the
disposition of all property acquired upon foreclosure of any such Trust Fund
Assets remaining in the Trust Fund and (ii) the purchase by the Master Servicer
or, if REMIC treatment has been elected and if specified in the related
Prospectus Supplement, by the holder of the residual interest in the REMIC (see
"Federal Income Tax Consequences"), from the related Trust Fund of all of the
remaining Trust Fund Assets and all property acquired in respect of such Trust
Fund Assets.
 
     Unless otherwise specified by the related Prospectus Supplement, any such
purchase of Trust Fund Assets and property acquired in respect of Trust Fund
Assets evidenced by a Series of Securities will be made at the option of the
Master Servicer, such other person or, if applicable, such holder of the REMIC
residual interest, at a price specified in the related Prospectus Supplement.
The exercise of such right will effect early retirement of the Securities of
that Series, but the right of the Master Servicer, such other person or, if
applicable, such holder of the REMIC residual interest, to so purchase is
subject to the principal balance of the related Trust Fund Assets being less
than the percentage specified in the related Prospectus Supplement of the
aggregate principal balance of the Trust Fund Assets at the Cut-off Date for the
Series. Upon such requirement being satisfied, the parties specified in the
related Prospectus Supplement may purchase all Trust Fund Assets and thereby
effect retirement of such Series of Securities. In such event, the applicable
purchase price will be sufficient to pay the aggregate outstanding principal
balance of such Series of Securities and any undistributed shortfall in interest
of such Series of Securities as will be described in the related Prospectus
Supplement. The foregoing is subject to the provision that if a REMIC election
is made with respect to a Trust Fund, any repurchase pursuant to clause (ii)
above will be made only in connection with a "qualified liquidation" of the
REMIC within the meaning of Section 860F(g)(4) of the Code.
 
     Indenture.  The Indenture will be discharged with respect to a Series of
Notes (except with respect to certain continuing rights specified in the
Indenture) upon the delivery to the Trustee for cancellation of all the Notes of
such Series or, with certain limitations, upon deposit with the Trustee of funds
sufficient for the payment in full of all of the Notes of such Series.
 
     In addition to such discharge with certain limitations, the Indenture will
provide that, if so specified with respect to the Notes of any Series, the
related Trust Fund will be discharged from any and all obligations in respect of
the Notes of such Series (except for certain obligations relating to temporary
Notes and exchange of Notes, to register the transfer of or exchange Notes of
such Series, to replace stolen, lost or mutilated Notes of such Series, to
maintain paying agencies and to hold monies for payment in trust) upon the
deposit with the Trustee, in trust, of money and/or direct obligations of or
obligations guaranteed by the United States of America which through the payment
of interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of and each
installment of interest on the Notes of such Series on the last scheduled
Distribution Date for such Notes and any installment of interest on such Notes
in accordance with the terms of the Indenture and the Notes of such Series. In
the event of any such defeasance and discharge of Notes of such Series, holders
of Notes of such Series would be able to look only
 
                                       77
<PAGE>   79
 
to such money and/or direct obligations for payment of principal and interest,
if any, on their Notes until maturity.
 
THE TRUSTEE
 
     The Trustee under each Agreement will be named in the applicable Prospectus
Supplement. The commercial bank or trust company serving as Trustee may have
normal banking relationships with the Depositor, the Master Servicer and any of
their respective affiliates.
 
                       CERTAIN LEGAL ASPECTS OF THE LOANS
 
     The following discussion contains summaries, which are general in nature,
of certain legal matters relating to the Loans. Because such legal aspects are
governed primarily by applicable state law (which laws may differ
substantially), the descriptions do not, except as expressly provided below,
reflect the laws of any particular state, nor to encompass the laws of all
states in which the security for the Loans is situated. The descriptions are
qualified in their entirety by reference to the applicable federal laws and the
appropriate laws of the states in which Loans may be originated.
 
GENERAL
 
     The Loans for a Series may be secured by deeds of trust, mortgages,
security deeds or deeds to secure debt, depending upon the prevailing practice
in the state in which the property subject to the loan is located. Deeds of
trust are used almost exclusively in California instead of mortgages. A mortgage
creates a lien upon the real property encumbered by the mortgage, which lien is
generally not prior to the lien for real estate taxes and assessments. Priority
between mortgages depends on their terms and generally on the order of recording
with a state or county office. There are two parties to a mortgage, the
mortgagor, who is the borrower and owner of the mortgaged property, and the
mortgagee, who is the lender. Under the mortgage instrument, the mortgagor
delivers to the mortgagee a note or bond and the mortgage. Although a deed of
trust is similar to a mortgage, a deed of trust formally has three parties, the
borrower-property owner called the trustor (similar to a mortgagor), a lender
(similar to a mortgagee) called the 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 obligation. A security deed and a deed to
secure debt are special types of deeds which indicate on their face that they
are granted to secure an underlying debt. By executing a security deed or deed
to secure debt, the grantor conveys title to, as opposed to merely creating a
lien upon, the subject property to the grantee until such time as the underlying
debt is repaid. The trustee's authority under a deed of trust, the mortgagee's
authority under a mortgage and the grantee's authority under a security deed or
deed to secure debt are governed by law and, with respect to some deeds of
trust, the directions of the beneficiary.
 
     Cooperatives.  Certain of Loans may be Cooperative Loans. The Cooperative
owns all the real property that comprises the project, including the land,
separate dwelling units and all common areas. The Cooperative is directly
responsible for project management and, in most cases, payment of real estate
taxes and hazard and liability insurance. If there is a blanket mortgage on the
Cooperative and/or underlying land, as is generally the case, the Cooperative,
as project mortgagor, is also responsible for meeting these mortgage
obligations. A blanket mortgage is ordinarily incurred by the Cooperative in
connection with the construction or purchase of the Cooperative's apartment
building. The interest of the occupant under proprietary leases or occupancy
agreements to which that Cooperative is a party are generally subordinate to the
interest of the holder of the blanket mortgage in that building. If the
Cooperative is unable to meet the payment obligations arising under its blanket
mortgage, the mortgagee holding the blanket mortgage could foreclose on that
mortgage and terminate all subordinate proprietary leases and occupancy
agreements. In addition, the blanket mortgage on a Cooperative may provide
financing in the form of a mortgage that does not fully amortize with a
significant portion of principal being due in one lump sum at final maturity.
The inability of the Cooperative to refinance this mortgage and its consequent
inability to make such final payment could lead to foreclosure by the mortgagee
providing the financing. A foreclosure in either event by the holder of the
blanket mortgage could
 
                                       78
<PAGE>   80
 
eliminate or significantly diminish the value of any collateral held by the
lender who financed the purchase by an individual tenant-stockholder of
Cooperative shares or, in the case of a Trust Fund including Cooperative Loans,
the collateral securing the Cooperative Loans.
 
     The Cooperative is owned by tenant-stockholders who, through ownership of
stock, shares or membership certificates in the corporation, receive proprietary
leases or occupancy agreements which confer exclusive rights to occupy specific
units. Generally, a tenant-stockholder of a Cooperative must make a monthly
payment to the Cooperative representing such tenant-stockholder's pro rata share
of the Cooperative's payments for its blanket mortgage, real property taxes,
maintenance expenses and other capital or ordinary expenses. An ownership
interest in a Cooperative and accompanying rights is financed through a
Cooperative share loan evidenced by a promissory note and secured by a security
interest in the occupancy agreement or proprietary lease and in the related
Cooperative shares. The lender takes possession of the share certificate and a
counterpart of the proprietary lease or occupancy agreement, and a financing
statement covering the proprietary lease or occupancy agreement and the
Cooperative shares is filed in the appropriate state and local offices to
perfect the lender's interest in its collateral. Subject to the limitations
discussed below, upon default of the tenant-stockholder, the lender may sue for
judgment on the promissory note, dispose of the collateral at a public or
private sale or otherwise proceed against the collateral or tenant-stockholder
as an individual as provided in the security agreement covering the assignment
of the proprietary lease or occupancy agreement and the pledge of Cooperative
shares.
 
FORECLOSURE/REPOSSESSION
 
     Deed of Trust.  Foreclosure of a deed of trust is generally accomplished by
a non-judicial sale under a specific provision in the deed of trust which
authorizes the trustee to sell the property at public auction upon any default
by the borrower under the terms of the note or deed of trust. In certain states,
such foreclosure also may be accomplished by judicial action in the manner
provided for foreclosure of mortgages. In addition to any notice requirements
contained in a deed of trust, in some states (such as California), the trustee
must record a notice of default and send a copy to the borrower-trustor, to any
person who has recorded a request for a copy of any notice of default and notice
of sale, to any successor in interest to the borrower-trustor, to the
beneficiary of any junior deed of trust and to certain other persons. In some
states (including California), 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 statutorily prescribed reinstatement period, cure a
monetary default by paying the entire amount in arrears plus other designated
costs and expenses incurred in enforcing the obligation. Generally, state law
controls the amount of foreclosure expenses and costs, including attorney's
fees, which may be recovered by a lender. After the reinstatement period has
expired without the default having been cured, the borrower or junior lienholder
no longer has the right to reinstate the loan and must pay the loan in full to
prevent the scheduled foreclosure sale. 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 (including California), published for a specific
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 real property. In California, the
entire process from recording a notice of default to a non-judicial sale usually
takes four to five months.
 
     Mortgages.  Foreclosure of a mortgage is generally accomplished by judicial
action. The action is initiated by the service of legal pleadings upon all
parties having an interest in the real property. Delays in completion of the
foreclosure may occasionally result from difficulties in locating necessary
parties. Judicial foreclosure proceedings are often not contested by any of the
parties. When the mortgagee's right to foreclosure is contested, the legal
proceedings necessary to resolve the issue can be time consuming. After the
completion of a judicial foreclosure proceeding, the court generally issues a
judgment of foreclosure and appoints a referee or other court officer to conduct
the sale of the property. In some states, mortgages may also be foreclosed by
advertisement, pursuant to a power of sale provided in the mortgage.
 
     Although foreclosure sales are typically public sales, frequently no third
party purchaser bids in excess of the lender's lien because of the difficulty of
determining the exact status of title to the property, the possible
deterioration of the property during the foreclosure proceedings and a
requirement that the purchaser pay for
 
                                       79
<PAGE>   81
 
the property in cash or by cashier's check. Thus the foreclosing lender often
purchases the property from the trustee or referee for an amount equal to the
principal amount outstanding under the loan, accrued and unpaid interest and the
expenses of foreclosure in which event the mortgagor's debt will be extinguished
or the lender may purchase for a lesser amount in order to preserve its right
against a borrower to seek a deficiency judgment in states where such judgment
is available. Thereafter, subject to the right of the borrower in some states to
remain in possession during the redemption period, the lender will assume the
burden 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 will commonly obtain the services of a real estate broker and
pay the broker's 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. Any loss may be
reduced by the receipt of any mortgage guaranty insurance proceeds.
 
     Courts have imposed general equitable principles upon foreclosure, which
are generally designed to mitigate the legal consequences to the borrower of the
borrower's defaults under the loan documents.
 
     Some courts have been faced with the issue of whether federal or state
constitutional provisions reflecting due process concerns for fair notice
require that borrowers under deeds of trust receive notice longer than that
prescribed by statute. For the most part, these cases have upheld the notice
provisions as being reasonable or have found that the sale by a trustee under a
deed of trust does not involve sufficient state action to afford constitutional
protection to the borrower.
 
     When the beneficiary under a junior mortgage or deed of trust cures the
default and reinstates or redeems by paying the full amount of the senior
mortgage or deed of trust, the amount paid by the beneficiary so to cure or
redeem becomes a part of the indebtedness secured by the junior mortgage or deed
of trust. See "-- Junior Mortgages; Rights of Senior Mortgagees" below.
 
     Cooperative Loans.  The Cooperative shares owned by the tenant-stockholder
and pledged to the lender are, in almost all cases, subject to restrictions on
transfer as set forth in the Cooperative's certificate of incorporation and
bylaws, as well as the proprietary lease or occupancy agreement, and may be
cancelled by the Cooperative for failure by the tenant-stockholder to pay rent
or other obligations or charges owed by such tenant-stockholder, including
mechanics' liens against the cooperative apartment building incurred by such
tenant-stockholder. The proprietary lease or occupancy agreement generally
permits the Cooperative to terminate such lease or agreement in the event an
obligor fails to make payments or defaults in the performance of covenants
required thereunder. Typically, the lender and the Cooperative enter into a
recognition agreement which establishes the rights and obligations of both
parties in the event of a default by the tenant-stockholder on its obligations
under the proprietary lease or occupancy agreement. A default by the
tenant-stockholder under the proprietary lease or occupancy agreement will
usually constitute a default under the security agreement between the lender and
the tenant-stockholder.
 
     The recognition agreement generally provides that, in the event that the
tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the Cooperative will take no action to terminate such lease or
agreement until the lender has been provided with an opportunity to cure the
default. The recognition agreement typically provides that if the proprietary
lease or occupancy agreement is terminated, the Cooperative will recognize the
lender's lien against proceeds form the sale of the Cooperative apartment,
subject, however, to the Cooperative's right to sums due under such proprietary
lease or occupancy agreement. The total amount owed to the Cooperative by the
tenant-stockholder, which the lender generally cannot restrict and does not
monitor, could reduce the value of the collateral below the outstanding
principal balance of the Cooperative Loan and accrued and unpaid interest
thereon.
 
     Recognition agreements also provide that in the event of a foreclosure on a
Cooperative Loan, the lender must obtain the approval or consent of the
Cooperative as required by the proprietary lease before transferring the
Cooperative shares or assigning the proprietary lease. Generally, the lender is
not limited in any rights it may have to dispossess the tenant-stockholders.
 
     In some states, foreclosure on the Cooperative shares is accomplished by a
sale in accordance with the provisions of Article 9 of the Uniform Commercial
Code (the "UCC") and the security agreement relating to
 
                                       80
<PAGE>   82
 
those shares. Article 9 of the UCC requires that a sale be conducted in a
"commercially reasonable" manner. Whether a foreclosure sale has been conducted
in a "commercially reasonable" manner will depend on the facts in each case. In
determining commercial reasonableness, a court will look to the notice given the
debtor and the method, manner, time, place and terms of the foreclosure.
Generally, a sale conducted according to the usual practice of banks selling
similar collateral will be considered reasonably conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to pay the costs and expenses of the sale and then to satisfy the
indebtedness secured by the lender's security interest. The recognition
agreement, however, generally provides that the lender's right to reimbursement
is subject to the right of the Cooperative to receive sums due under the
proprietary lease or occupancy agreement. If there are proceeds remaining, the
lender must account to the tenant-stockholder for the surplus. Conversely, if a
portion of the indebtedness remains unpaid, the tenant-stockholder is generally
responsible for the deficiency. See "-- Anti-Deficiency Legislation and Other
Limitations on Lenders" below.
 
     In the case of foreclosure on a building which was converted from a rental
building to a building owned by a Cooperative under a non-eviction plan, some
states require that a purchaser at a foreclosure sale take the property subject
to rent control and rent stabilization laws which apply to certain tenants who
elected to remain in the building but who did not purchase shares in the
Cooperative when the building was so converted.
 
ENVIRONMENTAL RISKS
 
     Real property pledged as security to a lender may subject the lender to
unforeseen environmental risks. Under the laws of certain states, contamination
of a property may give rise to a lien on the property to assure the payment of
the costs of clean-up. In several states such a lien has priority over the lien
of an existing mortgage against such property. In addition, under the federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980
("CERCLA"), the United States Environmental Protection Agency ("EPA") may impose
a lien on property where EPA has incurred clean-up costs. However, a CERCLA lien
is subordinate to pre-existing, perfected security interests.
 
     Under the laws of some states, and under CERCLA, there are circumstances
under which a secured lender may be held liable as an "owner" or "operator" for
the costs of addressing releases or threatened releases of hazardous substances
at a property, even though the environmental damage or threat was caused by a
prior or current owner or operator. CERCLA imposes liability for such costs on
any and all "responsible parties," including owners or operators. However,
CERCLA excludes from the definition of "owner or operator" a secured creditor
who holds indicia of ownership primarily to protect its security interest (the
"secured creditor exclusion") but without "participating in the management" of
the property. Thus, if a lender's activities begin to encroach on the actual
management of a contaminated facility or property, the lender may incur
liability as an "owner or operator" under CERCLA. Similarly, if a lender
forecloses and takes title to a contaminated facility or property, the lender
may incur CERCLA liability in various circumstances, including, but not limited
to, when it holds the facility or property as an investment (including leasing
the facility or property to a third party), or fails to dispose of the property
in a commercially reasonable time frame.
 
     The Asset Conservation, Lender Liability and Deposit Insurance Protection
Act of 1996 amended CERCLA to clarify when actions taken by a lender constitute
participation in the management of a mortgaged property, or the business of a
borrower, so as to render the secured creditor exemption unavailable to a
lender. It provides that, in order to be deemed to have participated in the
management of a mortgaged property, a lender must actually participate in the
operational affairs of the property or the borrower. The legislation also
provides that participation in the management of the property does not include
"merely having the capacity to influence, or unexercised right to control"
operations. Rather, a lender will lose the protection of the secured creditor
exemption only if it exercises decision-making control over the borrower's
environmental compliance and hazardous substance handling and disposal
practices, or assumes day-to-day management of all operational functions of the
mortgaged property.
 
     If a lender is or becomes liable, it can bring an action for contribution
against any other "responsible parties," including a previous owner or operator,
who created the environmental hazard, but those persons or
 
                                       81
<PAGE>   83
 
entities may be bankrupt or otherwise judgment proof. The costs associated with
environmental cleanup may be substantial. It is conceivable that costs arising
from the circumstances set forth above could result in a loss to
Certificateholders.
 
     A secured creditor exclusion does not govern liability for cleanup costs
under federal laws other than CERCLA except with respect to underground
petroleum storage tanks regulated under the federal Resource Conservation and
Recovery Act ("RCRA"). The Asset Conservation, Lender Liability and Deposit
Insurance Protection Act of 1996 amended RCRA so that the protections accorded
to lenders under CERCLA are also accorded to the holders of security interests
in underground petroleum storage tanks. It also endorsed EPA's lender liability
rule for underground petroleum storage tanks under Subtitle I of RCRA. Under
this rule, a holder of a security interest in an underground petroleum storage
tank or real property containing an underground petroleum storage tank is not
considered an operator of the underground petroleum storage tank as long as
petroleum is not added to, stored in or dispensed from the tank. It should be
noted, however, that liability for cleanup of petroleum contamination may be
governed by state law, which may not provide for any specific protection for
secured creditors.
 
     Except as otherwise specified in the related Prospectus Supplement, at the
time the Loans were originated, no environmental assessment or a very limited
environmental assessment of the Properties was conducted.
 
RIGHTS OF REDEMPTION
 
     In some states, after sale pursuant to 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 certain
other states (including California), this right of redemption applies only to
sales following judicial foreclosure, and not to sales 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 other states, redemption may be
authorized if the former borrower pays only a portion of the sums due. The
effect of a statutory 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 from the lender subsequent to
foreclosure or sale under a deed of trust. Consequently, the practical effect of
the redemption right is to force the lender to retain the property and pay the
expenses of ownership until the redemption period has run. In some states, there
is no right to redeem property after a trustee's sale under a deed of trust.
 
ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS
 
     Certain states have imposed statutory and judicial restrictions that limit
the remedies of a beneficiary under a deed of trust or a mortgagee under a
mortgage. In some states, including California, statutes and case law limit the
right of the beneficiary or mortgagee to obtain a deficiency judgment against
borrowers financing the purchase of their residence or following sale under a
deed of trust or certain other foreclosure proceedings. 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 fair market value of the real
property at the time of the foreclosure sale. As a result of these prohibitions,
it is anticipated that in most instances the Master Servicer will utilize the
non-judicial foreclosure remedy and will not seek deficiency judgments against
defaulting borrowers.
 
     Some state statutes 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 certain other states, the lender has the option of bringing a personal action
against the borrower on the debt without first exhausting such security;
however, in some of these states, the lender, following judgment on such
personal action, may be deemed to have elected a remedy and may be precluded
from exercising remedies with respect to 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. In some states, exceptions to the anti-deficiency
statutes are provided
 
                                       82
<PAGE>   84
 
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. Finally, other statutory provisions 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 public sale. The purpose of these statutes is generally 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.
 
     Generally, Article 9 of the UCC governs foreclosure on Cooperative shares
and the related proprietary lease or occupancy agreement. Some courts have
interpreted section 9-504 of the UCC to prohibit a deficiency award unless the
creditor establishes that the sale of the collateral (which, in the case of a
Cooperative Loan, would be the shares of the Cooperative and the related
proprietary lease or occupancy agreement) was conducted in a commercially
reasonable manner.
 
     In addition to anti-deficiency and related legislation, numerous other
federal and state statutory provisions, including the federal bankruptcy laws
and state laws affording relief to debtors, may interfere with or affect the
ability of the secured mortgage lender to realize upon its security. For
example, in a proceeding under the federal Bankruptcy Code, a lender may not
foreclose on a mortgaged property without the permission of the bankruptcy
court. The rehabilitation plan proposed by the debtor may provide, if the
mortgaged property is not the debtor's principal residence and the court
determines that the value of the mortgaged property is less than the principal
balance of the mortgage loan, for the reduction of the secured indebtedness to
the value of the mortgaged property as of the date of the commencement of the
bankruptcy, rendering the lender a general unsecured creditor for the
difference, and also may reduce the monthly payments due under such mortgage
loan, change the rate of interest and alter the mortgage loan repayment
schedule. The effect of any such proceedings under the federal Bankruptcy Code,
including but not limited to any automatic stay, could result in delays in
receiving payments on the Loans underlying a Series of Securities and possible
reductions in the aggregate amount of such payments.
 
     The federal tax laws provide priority to certain tax liens over the lien of
a mortgage or secured party.
 
DUE-ON-SALE CLAUSES
 
     Unless otherwise specified in the related Prospectus Supplement, each
conventional Loan will contain a due-on-sale clause which will generally provide
that if the mortgagor or obligor sells, transfers or conveys the Property, the
loan or contract may be accelerated by the mortgagee or secured party. Court
decisions and legislative actions have placed substantial restriction on the
right of lenders to enforce such clauses in many states. For instance, the
California Supreme Court in August 1978 held that due-on-sale clauses were
generally unenforceable. However, the Garn-St Germain Depository Institutions
Act of 1982 (the "Garn-St Germain Act"), subject to certain exceptions, preempts
state constitutional, statutory and case law prohibiting the enforcement of
due-on-sale clauses. As a result, due-on-sale clauses have become generally
enforceable except in those states whose legislatures exercised their authority
to regulate the enforceability of such clauses with respect to mortgage loans
that were (i) originated or assumed during the "window period" under the Garn-St
Germain Act which ended in all cases not later than October 15, 1982, and (ii)
originated by lenders other than national banks, federal savings institutions
and federal credit unions. FHLMC has taken the position in its published
mortgage servicing standards that, out of a total of eleven "window period
states," five states (Arizona, Michigan, Minnesota, New Mexico and Utah) have
enacted statutes extending, on various terms and for varying periods, the
prohibition on enforcement of due-on-sale clauses with respect to certain
categories of window period loans. Also, the Garn-St Germain Act does
"encourage" lenders to permit assumption of loans at the original rate of
interest or at some other rate less than the average of the original rate and
the market rate.
 
     As to loans secured by an owner-occupied residence, the Garn-St Germain Act
sets forth nine specific instances in which a mortgagee covered by the Act may
not exercise its rights under a due-on-sale clause, notwithstanding the fact
that a transfer of the property may have occurred. The inability to enforce a
due-on-sale clause may result in transfer of the related Property to an
uncreditworthy person, which could increase the likelihood of default or may
result in a mortgage bearing an interest rate below the current market rate
being
 
                                       83
<PAGE>   85
 
assumed by a new home buyer, which may affect the average life of the Loans and
the number of Loans which may extend to maturity.
 
     In addition, under federal bankruptcy law, due-on-sale clauses may not be
enforceable in bankruptcy proceedings and may, under certain circumstances, be
eliminated in any modified mortgage resulting from such bankruptcy proceeding.
 
ENFORCEABILITY OF PREPAYMENT AND LATE PAYMENT FEES
 
     Forms of notes, mortgages and deeds of trust used by lenders may contain
provisions obligating the borrower to pay a late charge if payments are not
timely made, and in some circumstances may provide for prepayment fees or
penalties if the obligation is paid prior to maturity. In certain states, there
are or may be specific limitations upon the late charges which a lender may
collect from a borrower for delinquent payments. Certain states also limit the
amounts that a lender may collect from a borrower as an additional charge if the
loan is prepaid. Under certain state laws, prepayment charges may not be imposed
after a certain period of time following the origination of mortgage loans with
respect to prepayments on loans secured by liens encumbering owner-occupied
residential properties. Since many of the Properties will be owner-occupied, it
is anticipated that prepayment charges may not be imposed with respect to many
of the Loans. The absence of such a restraint on prepayment, particularly with
respect to fixed rate Loans having higher Loan Rates, may increase the
likelihood of refinancing or other early retirement of such loans or contracts.
Late charges and prepayment fees are typically retained by servicers as
additional servicing compensation.
 
APPLICABILITY OF USURY LAWS
 
     Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ("Title V") provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. The Office of Thrift
Supervision, as successor to the Federal Home Loan Bank Board, is authorized to
issue rules and regulations and to publish interpretations governing
implementation of Title V. The statute authorized the states to reimpose
interest rate limits by adopting, before April 1, 1983, a law or constitutional
provision which expressly rejects an application of the federal law. Fifteen
states adopted such a law prior to the April 1, 1983 deadline. In addition, even
where Title V is not so rejected, any state is authorized by the law to adopt a
provision limiting discount points or other charges on mortgage loans covered by
Title V. Certain states have taken action to reimpose interest rate limits
and/or to limit discount points or other charges.
 
THE CONTRACTS
 
     General.  The Contracts, other than those Contracts that are unsecured or
secured by mortgages on real estate (such Contracts are hereinafter referred to
in this section as "contracts") generally are "chattel paper" or constitute
"purchase money security interests" each as defined in the UCC. Pursuant to the
UCC, the sale of chattel paper is treated in a manner similar to perfection of a
security interest in chattel paper. Under the related Agreement, the Depositor
will transfer physical possession of the contracts to the Trustee or a
designated custodian or may retain possession of the contracts as custodian for
the Trustee. In addition, the Depositor will make an appropriate filing of a
UCC-1 financing statement in the appropriate states to, among other things, give
notice of the Trust Fund's ownership of the contracts. Unless otherwise
specified in the related Prospectus Supplement, the contracts will not be
stamped or otherwise marked to reflect their assignment from the Depositor to
the Trustee. With respect to each transaction, a decision will be made as to
whether or not the contracts will be stamped or otherwise marked to reflect
their assignment from the Depositor to the Trustee, based upon, among other
things, the practices and procedures of the related Originator and Master
Servicer and after consultation with the applicable Rating Agency or Rating
Agencies. Therefore, if the contracts are not stamped or otherwise marked to
reflect their assignment from the Depositor to the Trustee and through
negligence, fraud or otherwise, a subsequent purchaser were able to take
physical possession of the contracts without notice of such assignment, the
Trust Fund's interest in the contracts could be defeated. See "Risk
Factors -- Security Interest Risks Associated with Certain Loans."
 
                                       84
<PAGE>   86
 
     Security Interests in Home Improvements.  The contracts that are secured by
the Home Improvements financed thereby grant to the originator of such contracts
a purchase money security interest in such Home Improvements to secure all or
part of the purchase price of such Home Improvements and related services. A
financing statement generally is not required to be filed to perfect a purchase
money security interest in consumer goods. Such purchase money security
interests are assignable. In general, a purchase money security interest grants
to the holder a security interest that has priority over a conflicting security
interest in the same collateral and the proceeds of such collateral. However, to
the extent that the collateral subject to a purchase money security interest
becomes a fixture, in order for the related purchase money security interest to
take priority over a conflicting interest in the fixture, the holder's interest
in such Home Improvement must generally be perfected by a timely fixture filing.
In general, a security interest does not exist under the UCC in ordinary
building material incorporated into an improvement on land. Home Improvement
Contracts that finance lumber, bricks, other types of ordinary building material
or other goods that are deemed to lose such characterization upon incorporation
of such materials into the related property, will not be secured by a purchase
money security interest in the Home Improvement being financed.
 
     Enforcement of Security Interest in Home Improvements.  So long as the Home
Improvement has not become subject to the real estate law, a creditor can
repossess a Home Improvement 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, prior to commencement of any repossession. The UCC and consumer
protection laws in 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 prior to resale of the unit that the debtor may redeem
at or before such resale.
 
     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 property 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.
 
     Security Interests in the Manufactured Homes.  The Manufactured Homes
securing the Manufactured Housing 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. Unless otherwise specified in
the related Prospectus Supplement, the security interests of the related Trustee
in the Manufactured Homes will not be noted on the certificates of title or by
delivery of the required documents and payment of fees to the applicable state
motor vehicle authorities. With respect to each transaction, a decision will be
made as to whether or not the security interests of the related Trustee in the
Manufactured Homes will be noted on the certificates of title and the required
documents and fees will be delivered to the applicable state motor vehicle
authorities based upon, among other things, the practices and procedures of the
related Originator and Master Servicer and after consultation with the
applicable Rating Agency or Rating Agencies. See "Risk Factors -- Security
Interest Risks Associated with Certain Loans." In some nontitle states,
perfection pursuant to the provisions of the UCC is required. As manufactured
homes have become large 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 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 manufactured home under applicable state
real estate law. In order to perfect a security interest in a manufactured home
under real estate laws, the secured party 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. These filings must be made in the
real estate records office of the county where the manufactured home is located.
If so specified in the related
 
                                       85
<PAGE>   87
 
Prospectus Supplement, the Manufactured Housing Contracts may 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 is permanently attached to its site, the related lender may be
required to perfect a security interest in the Manufactured Home under
applicable real estate laws.
 
     In the event that the owner of a Manufactured Home moves it to a state
other than the state in which such 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 such relocation and
thereafter only if and after the owner re-registers the Manufactured Home in
such state. If the owner were to relocate a Manufactured Home to another state
and not re-register a security interest in such 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, the secured party must surrender possession if
it holds the certificate of title to such Manufactured Home or, in the case of
Manufactured Homes registered in states which provide for notation of lien on
the certificate of title, notice of surrender would be given to the secured
party noted on the certificate of title. In states which do not require a
certificate of title for registration of a manufactured home, re-registration
could defeat perfection.
 
     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 in the Manufactured Home.
 
     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 certain related lenders and assignees) to transfer such
contract free of notice of claims by the debtor thereunder. The effect of this
rule is to subject the assignee of such a contract to all claims and defenses
which the debtor could assert against the seller of goods. 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 Trustee against such obligor. Numerous other federal and
state consumer protection laws impose requirements applicable to the origination
and lending pursuant to 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
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.
 
     Applicability of Usury Laws.  Title V of the Depository Institutions
Deregulation and Monetary Control Act of 1980, as amended ("Title V"), provides
that, subject to the following conditions, state usury limitations shall not
apply to any contract which is secured by a first lien on certain kinds of
consumer goods. The contracts would be covered if they satisfy certain
conditions governing, among other things, the terms of any prepayments, late
charges and deferral fees and requiring a 30-day notice period prior to
instituting any action leading to repossession of 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 so rejected, any state is authorized by the law to adopt a
provision limiting discount points or other charges on loans covered by Title V.
 
INSTALLMENT CONTRACTS
 
     The Loans may also consist of installment contracts. Under an installment
contract ("Installment Contract") the seller (hereinafter referred to in this
section as the "lender") retains legal title to the property and enters into an
agreement with the purchaser hereinafter referred to in this section as the
"borrower") for the payment of the purchase price, plus interest, over the term
of such contract. Only after full performance by the borrower of the contract is
the lender obligated to convey title to the property to the purchaser. As with
 
                                       86
<PAGE>   88
 
mortgage or deed of trust financing, during the effective period of the
Installment Contract, the borrower is generally responsible for maintaining the
property in good condition and for paying real estate taxes, assessments and
hazard insurance premiums associated with the property.
 
     The method of enforcing the rights of the lender under an Installment
Contract varies on a state-by-state basis depending upon the extent to which
state courts are willing, or able pursuant to state statute, to enforce the
contract strictly according to its terms. The terms of Installment Contracts
generally provide that upon a default by the borrower, the borrower loses his or
her right to occupy the property, the entire indebtedness is accelerated, and
the buyer's equitable interest in the property is forfeited. The lender in such
a situation does not have to foreclose in order to obtain title to the property,
although in some cases a quiet title action is in order if the borrower has
filed the Installment Contract in local land records and an ejectment action may
be necessary to recover possession. In a few states, particularly in cases of
borrower default during the early years of an Installment Contract, the courts
will permit ejectment of the buyer and a forfeiture of his or her interest in
the property. However, most state legislatures have enacted provisions by
analogy to mortgage law protecting borrowers under Installment Contracts from
the harsh consequences of forfeiture. Under such statutes, a judicial or
nonjudicial foreclosure may be required, the lender may be required to give
notice of default and the borrower may be granted some grace period during which
the Installment Contract may be reinstated upon full payment of the default
amount and the borrower may have a post-foreclosure statutory redemption right.
In other states, courts in equity may permit a borrower with significant
investment in the property under an Installment Contract for the sale of real
estate to share in the proceeds of sale of the property after the indebtedness
is repaid or may otherwise refuse to enforce the forfeiture clause.
Nevertheless, generally speaking, the lender's procedures for obtaining
possession and clear title under an Installment Contract in a given state are
simpler and less time-consuming and costly than are the procedures for
foreclosing and obtaining clear title to a property subject to one or more
liens.
 
SOLDIERS' AND SAILORS' CIVIL RELIEF ACT
 
     Generally, under the terms of the Soldiers' and Sailors' Civil Relief Act
of 1940, as amended (the "Relief Act"), a borrower who enters military service
after the origination of such borrower's Loan (including a borrower who is a
member of the National Guard or is in reserve status at the time of the
origination of the Loan and is later called to active duty) may not be charged
interest above an annual rate of 6% during the period of such borrower's active
duty status, unless a court orders otherwise upon application of the lender. It
is possible that such interest rate limitation could have an effect, for an
indeterminate period of time, on the ability of the Master Servicer to collect
full amounts of interest on certain of the Loans. Unless otherwise provided in
the related Prospectus Supplement, any shortfall in interest collections
resulting from the application of the Relief Act could result in losses to
Securityholders. The Relief Act also imposes limitations which would impair the
ability of the Master Servicer to foreclose on an affected Loan during the
borrower's period of active duty status. Moreover, the Relief Act permits the
extension of a Loan's maturity and the re-adjustment of its payment schedule
beyond the completion of military service. Thus, in the event that such a Loan
goes into default, there may be delays and losses occasioned by the inability to
realize upon the Property in a timely fashion.
 
JUNIOR MORTGAGES; RIGHTS OF SENIOR MORTGAGEES
 
     To the extent that the Loans comprising the Trust Fund for a Series are
secured by mortgages which are junior to other mortgages held by other lenders
or institutional investors, the rights of the Trust Fund (and therefore the
Securityholders), as mortgagee under any such junior mortgage, are subordinate
to those of any mortgagee under any senior mortgage. The senior mortgagee has
the right to receive hazard insurance and condemnation proceeds and to cause the
property securing the Loan to be sold upon default of the mortgagor, thereby
extinguishing the junior mortgagee's lien unless the junior mortgagee asserts
its subordinate interest in the property in foreclosure litigation and,
possibly, satisfies the defaulted senior mortgage. A junior mortgagee may
satisfy a defaulted senior loan in full and, in some states, may cure a default
and bring the senior loan current, in either event adding the amounts expended
to the balance due on the junior loan. In most states,
 
                                       87
<PAGE>   89
 
absent a provision in the mortgage or deed of trust, no notice of default is
required to be given to a junior mortgagee.
 
     The standard form of the mortgage used by most institutional lenders
confers on the mortgagee the right both to receive all proceeds collected under
any hazard insurance policy and all awards made in connection with condemnation
proceedings, and to apply such proceeds and awards to any indebtedness secured
by the mortgage, in such order as the mortgagee may determine. Thus, in the
event improvements on the property are damaged or destroyed by fire or other
casualty, or in the event the property is taken by condemnation, the mortgagee
or beneficiary under senior mortgages will have the prior right to collect any
insurance proceeds payable under a hazard insurance policy and any award of
damages in connection with the condemnation and to apply the same to the
indebtedness secured by the senior mortgages. Proceeds in excess of the amount
of senior mortgage indebtedness, in most cases, may be applied to the
indebtedness of a junior mortgage.
 
     Another provision sometimes found in the form of the mortgage or deed of
trust used by institutional lenders obligates the mortgagor to pay before
delinquency all taxes and assessments on the property and, when due, all
encumbrances, charges and liens on the property which appear prior to the
mortgage or deed of trust, to provide and maintain fire insurance on the
property, to maintain and repair the property and not to commit or permit any
waste thereof, and to appear in and defend any action or proceeding purporting
to affect the property or the rights of the mortgagee under the mortgage. Upon a
failure of the mortgagor to perform any of these obligations, the mortgagee is
given the right under certain mortgages to perform the obligation itself, at its
election, with the mortgagor agreeing to reimburse the mortgagee for any sums
expended by the mortgagee on behalf of the mortgagor. All sums so expended by
the mortgagee become part of the indebtedness secured by the mortgage.
 
     The form of credit line trust deed or mortgage generally used by most
institutional lenders which make Revolving Credit Line Loans typically contains
a "future advance" clause, which provides, in essence, that additional amounts
advanced to or on behalf of the borrower by the beneficiary or lender are to be
secured by the deed of trust or mortgage. Any amounts so advanced after the
Cut-off Date with respect to any Mortgage will not be included in the Trust
Fund. The priority of the lien securing any advance made under the clause may
depend in most states on whether the deed of trust or mortgage is called and
recorded as a credit line deed of trust or mortgage. If the beneficiary or
lender advances additional amounts, the advance is entitled to receive the same
priority as amounts initially advanced under the trust deed or mortgage,
notwithstanding the fact that there may be junior trust deeds or mortgages and
other liens which intervene between the date of recording of the trust deed or
mortgage and the date of the future advance, and notwithstanding that the
beneficiary or lender had actual knowledge of such intervening junior trust
deeds or mortgages and other liens at the time of the advance. In most states,
the trust deed or mortgage lien securing mortgage loans of the type which
includes home equity credit lines applies retroactively to the date of the
original recording of the trust deed or mortgage, provided that the total amount
of advances under the home equity credit line does not exceed the maximum
specified principal amount of the recorded trust deed or mortgage, except as to
advances made after receipt by the lender of a written notice of lien from a
judgment lien creditor of the trustor.
 
THE TITLE I PROGRAM
 
     General.  Certain of the Loans contained in a Trust Fund may be loans
insured under the FHA Title I Credit Insurance program created pursuant to
Sections 1 and 2(a) of the National Housing Act of 1934 (the "Title I Program").
Under the Title I Program, the FHA is authorized and empowered to insure
qualified lending institutions against losses on eligible loans. The Title I
Program operates as a coinsurance program in which the FHA insures up to 90% of
certain losses incurred on an individual insured loan, including the unpaid
principal balance of the loan, but only to the extent of the insurance coverage
available in the lender's FHA insurance coverage reserve account. The owner of
the loan bears the uninsured loss on each loan.
 
     The types of loans which are eligible for insurance by the FHA under the
Title I Program include property improvement loans ("Property Improvement Loans"
or "Title I Loans"). A Property Improvement Loan or Title I Loan means a loan
made to finance actions or items that substantially protect or improve the basic
livability or utility of a property and includes single family improvement
loans.
 
                                       88
<PAGE>   90
 
     There are two basic methods of lending or originating such loans which
include a "direct loan" or a "dealer loan." With respect to a direct loan, the
borrower makes application directly to a lender without any assistance from a
dealer, which application may be filled out by the borrower or by a person
acting at the direction of the borrower who does not have a financial interest
in the loan transaction, and the lender may disburse the loan proceeds solely to
the borrower or jointly to the borrower and other parties to the transaction.
With respect to a dealer loan, the dealer, who has a direct or indirect
financial interest in the loan transaction, assists the borrower in preparing
the loan application or otherwise assists the borrower in obtaining the loan
from lender and the lender may distribute proceeds solely to the dealer or the
borrower or jointly to the borrower and the dealer or other parties. With
respect to a dealer Title I Loan, a dealer may include a seller, a contractor or
supplier of goods or services.
 
     Loans insured under the Title I Program are required to have fixed interest
rates and, generally, provide for equal installment payments due weekly,
biweekly, semi-monthly or monthly, except that a loan may be payable quarterly
or semi-annually in order to correspond with the borrower's irregular flow of
income. The first or last payments (or both) may vary in amount but may not
exceed 150% of the regular installment payment, and the first payment may be due
no later than two months from the date of the loan. The note must contain a
provision permitting full or partial prepayment of the loan. The interest rate
may be established by the lender and must be fixed for the term of the loan and
recited in the note. Interest on an insured loan must accrue from the date of
the loan and be calculated according to the actuarial method. The lender must
assure that the note and all other documents evidencing the loan are in
compliance with applicable federal, state and local laws.
 
     Each insured lender is required to use prudent lending standards in
underwriting individual loans and to satisfy the applicable loan underwriting
requirements under the Title I Program prior to its approval of the loan and
disbursement of loan proceeds. Generally, the lender must exercise prudence and
diligence to determine whether the borrower and any co-maker is solvent and an
acceptable credit risk, with a reasonable ability to make payments on the loan
obligation. The lender's credit application and review must determine whether
the borrower's income will be adequate to meet the periodic payments required by
the loan, as well as the borrower's other housing and recurring expenses, which
determination must be made in accordance with the expense-to-income ratios
published by the Secretary of HUD.
 
     Under the Title I Program, the FHA does not review or approve for
qualification for insurance the individual loans insured thereunder at the time
of approval by the lending institution (as is typically the case with other
federal loan programs). If, after a loan has been made and reported for
insurance under the Title I Program, the lender discovers any material
misstatement of fact or that the loan proceeds have been misused by the
borrower, dealer or any other party, it shall promptly report this to the FHA.
In such case, provided that the validity of any lien on the property has not
been impaired, the insurance of the loan under the Title I Program will not be
affected unless such material misstatements of fact or misuse of loan proceeds
was caused by (or was knowingly sanctioned by) the lender or its employees.
 
     Requirements for Title I Loans.  The maximum principal amount for Title I
Loans must not exceed the actual cost of the project plus any applicable fees
and charges allowed under the Title I Program; provided that such maximum amount
does not exceed $25,000 (or the current applicable amount) for a single family
property improvement loan. Generally, the term of a Title I Loan may not be less
than six months nor greater than 20 years and 32 days. A borrower may obtain
multiple Title I Loans with respect to multiple properties, and a borrower may
obtain more than one Title I Loan with respect to a single property, in each
case as long as the total outstanding balance of all Title I Loans in the same
property does not exceed the maximum loan amount for the type of Title I Loan
thereon having the highest permissible loan amount.
 
     Borrower eligibility for a Title I Loan requires that the borrower have at
least a one-half interest in either fee simple title to the real property, a
lease thereof for a term expiring at least six months after the final maturity
of the Title I Loan or a recorded land installment contract for the purchase of
the real property, and that the borrower have equity in the property being
improved at least equal to the amount of the Title I Loan if such loan amount
exceeds $15,000. Any Title I Loan in excess of $7,500 must be secured by a
recorded lien on
 
                                       89
<PAGE>   91
 
the improved property which is evidenced by a mortgage or deed of trust executed
by the borrower and all other owners in fee simple.
 
     The proceeds from a Title I Loan may be used only to finance property
improvements which substantially protect or improve the basic livability or
utility of the property as disclosed in the loan application. The Secretary of
HUD has published a list of items and activities which cannot be financed with
proceeds from any Title I Loan and from time to time the Secretary of HUD may
amend such list of items and activities. With respect to any dealer Title I
Loan, before the lender may disburse funds, the lender must have in its
possession a completion certificate on a HUD approved form, signed by the
borrower and the dealer. With respect to any direct Title I Loan, the lender is
required to obtain, promptly upon completion of the improvements but not later
than six months after disbursement of the loan proceeds with one six month
extension if necessary, a completion certificate, signed by the borrower. The
lender is required to conduct an on-site inspection on any Title I Loan where
the principal obligation is $7,500 or more, and on any direct Title I Loan where
the borrower fails to submit a completion certificate.
 
     FHA Insurance Coverage.  Under the Title I Program, the FHA establishes an
insurance coverage reserve account for each lender which has been granted a
Title I insurance contract. The amount of insurance coverage in this account is
10% of the amount disbursed, advanced or expended by the lender in originating
or purchasing eligible loans registered with FHA for Title I insurance, with
certain adjustments. The balance in the insurance coverage reserve account is
the maximum amount of insurance claims the FHA is required to pay. Loans to be
insured under the Title I Program will be registered for insurance by the FHA
and the insurance coverage attributable to such loans will be included in the
insurance coverage reserve account for the originating or purchasing lender
following the receipt and acknowledgment by the FHA of a loan report on the
prescribed form pursuant to the Title I regulations. The FHA charges a fee of
0.50% per annum of the net proceeds (the original balance) of any eligible loan
so reported and acknowledged for insurance by the originating lender. The FHA
bills the lender for the insurance premium on each insured loan annually, on
approximately the anniversary date of the loan's origination. If an insured loan
is prepaid during the year, FHA will not refund or abate the insurance premium.
 
     Under the Title I Program the FHA will reduce the insurance coverage
available in the lender's FHA insurance coverage reserve account with respect to
loans insured under the lender's contract of insurance by (i) the amount of the
FHA insurance claims approved for payment relating to such insured loans and
(ii) the amount of insurance coverage attributable to insured loans sold by the
lender, and such insurance coverage may be reduced for any FHA insurance claims
rejected by the FHA. The balance of the lender's FHA insurance coverage reserve
account will be further adjusted as required under Title I or by the FHA, and
the insurance coverage therein may be earmarked with respect to each or any
eligible loans insured thereunder, if a determination is made by the Secretary
of HUD that it is in its interest to do so. Origination and acquisitions of new
eligible loans will continue to increase a lender's insurance coverage reserve
account balance by 10% of the amount disbursed, advanced or expended in
originating or acquiring such eligible loans registered with the FHA for
insurance under the Title I Program. The Secretary of HUD may transfer insurance
coverage between insurance coverage reserve accounts with earmarking with
respect to a particular insured loan or group of insured loans when a
determination is made that it is in the Secretary's interest to do so.
 
     The lender may transfer (except as collateral in a bona fide transaction)
insured loans and loans reported for insurance only to another qualified lender
under a valid Title I contract of insurance. Unless an insured loan is
transferred with recourse or with a guaranty or repurchase agreement, the FHA,
upon receipt of written notification of the transfer of such loan in accordance
with the Title I regulations, will transfer from the transferor's insurance
coverage reserve account to the transferee's insurance coverage reserve account
an amount, if available, equal to 10% of the actual purchase price or the net
unpaid principal balance of such loan (whichever is less). However, under the
Title I Program not more than $5,000 in insurance coverage shall be transferred
to or from a lender's insurance coverage reserve account during any October 1 to
September 30 period without the prior approval of the Secretary of HUD.
 
     Claims Procedures Under Title I.  Under the Title I Program the lender may
accelerate an insured loan following a default on such loan only after the
lender or its agent has contacted the borrower in a face-to-face
 
                                       90
<PAGE>   92
 
meeting or by telephone to discuss the reasons for the default and to seek its
cure. If the borrower does not cure the default or agree to a modification
agreement or repayment plan, the lender will notify the borrower in writing
that, unless within 30 days the default is cured or the borrower enters into a
modification agreement or repayment plan, the loan will be accelerated and that,
if the default persists, the lender will report the default to an appropriate
credit agency. The lender may rescind the acceleration of maturity after full
payment is due and reinstate the loan only if the borrower brings the loan
current, executes a modification agreement or agrees to an acceptable repayment
plan.
 
     Following acceleration of maturity upon a secured Title I Loan, the lender
may either (a) proceed against the property under any security instrument, or
(b) make a claim under the lender's contract of insurance. If the lender chooses
to proceed against the property under a security instrument (or if it accepts a
voluntary conveyance or surrender of the property), the lender may file an
insurance claim only with the prior approval of the Secretary of HUD.
 
     When a lender files an insurance claim with the FHA under the Title I
Program, the FHA reviews the claim, the complete loan file and documentation of
the lender's efforts to obtain recourse against any dealer who has agreed
thereto, certification of compliance with applicable state and local laws in
carrying out any foreclosure or repossession, and evidence that the lender has
properly filed proofs of claims, where the borrower is bankrupt or deceased.
Generally, a claim for reimbursement for loss on any Title I Loan must be filed
with the FHA no later than nine months after the date of default of such loan.
Concurrently with filing the insurance claim, the lender shall assign to the
United States of America the lender's entire interest in the loan note (or a
judgment in lieu of the note), in any security held and in any claim filed in
any legal proceedings. If, at the time the note is assigned to the United
States, the Secretary has reason to believe that the note is not valid or
enforceable against the borrower, the FHA may deny the claim and reassign the
note to the lender. If either such defect is discovered after the FHA has paid a
claim, the FHA may require the lender to repurchase the paid claim and to accept
a reassignment of the loan note. If the lender subsequently obtains a valid and
enforceable judgment against the borrower, the lender may resubmit a new
insurance claim with an assignment of the judgment. The FHA may contest any
insurance claim and make a demand for repurchase of the loan at any time up to
two years from the date the claim was certified for payment and may do so
thereafter in the event of fraud or misrepresentation on the part of the lender.
 
     Under the Title I Program the amount of an FHA insurance claim payment,
when made, is equal to the Claimable Amount, up to the amount of insurance
coverage in the lender's insurance coverage reserve account. For the purposes
hereof, the "Claimable Amount" means an amount equal to 90% of the sum of: (a)
the unpaid loan obligation (net unpaid principal and the uncollected interest
earned to the date of default) with adjustments thereto if the lender has
proceeded against property securing such loan; (b) the interest on the unpaid
amount of the loan obligation from the date of default to the date of the
claim's initial submission for payment plus 15 calendar days (but not to exceed
9 months from the date of default), calculated at the rate of 7% per annum; (c)
the uncollected court costs; (d) the attorney's fees not to exceed $500; and (e)
the expenses for recording the assignment of the security to the United States.
 
CONSUMER PROTECTION LAWS
 
     Numerous federal and state consumer protection laws impose substantive
requirements upon mortgage lenders in connection with the origination, servicing
and enforcement of loans secured by Single Family Properties. These laws include
the federal Truth-in-Lending Act and Regulation Z promulgated thereunder, Real
Estate Settlement Procedures Act and Regulation B promulgated thereunder, Equal
Credit Opportunity Act, Fair Credit Billing Act, Fair Credit Reporting Act and
related statutes and regulations. In particular, Regulation Z requires certain
disclosures to the borrowers regarding the terms of the Loans; the Equal Credit
Opportunity Act and Regulation B promulgated thereunder prohibit discrimination
on the basis of age, race, color, sex, religion, marital status, national
origin, receipt of public assistance or the exercise of any right under the
Consumer Credit Protection Act, in the extension of credit; and the Fair Credit
Reporting Act regulates the use and reporting of information related to the
borrower's credit experience. Certain provisions of these laws impose specific
statutory liabilities upon lenders who fail to comply therewith. In addition,
violations of
 
                                       91
<PAGE>   93
 
such laws may limit the ability of the Sellers to collect all or part of the
principal of or interest on the Loans and could subject the Sellers and in some
case their assignees to damages and administrative enforcement.
 
                        FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     The following is a summary of the material anticipated federal income tax
consequences of the purchase, ownership, and disposition of the Securities and
is based on advice of Andrews & Kurth L.L.P., special counsel to the Depositor,
or other counsel identified in the Prospectus Supplement. The summary is based
upon the provisions of the Code, the regulations promulgated thereunder,
including, where applicable, proposed regulations, and the judicial and
administrative rulings and decisions now in effect, all of which are subject to
change or possible differing interpretations. The statutory provisions,
regulations, and interpretations on which this interpretation is based are
subject to change, and such a change could apply retroactively.
 
     The summary does not purport to deal with all aspects of federal income
taxation that may affect particular investors in light of their individual
circumstances, nor with certain types of investors subject to special treatment
under the federal income tax laws. This summary focuses primarily upon investors
who will hold Securities as "capital assets" (generally, property held for
investment) within the meaning of Section 1221 of the Code, but much of the
discussion is applicable to other investors as well. Prospective investors are
advised to consult their own tax advisers concerning the federal, state, local
and any other tax consequences to them of the purchase, ownership and
disposition of the Securities.
 
     The federal income tax consequences to holders of Securities will vary
depending on whether (i) the Securities of a Series are classified as
indebtedness; (ii) an election is made to treat the Trust Fund relating to a
particular Series of Securities as a real estate mortgage investment conduit
("REMIC") under the Internal Revenue Code of 1986, as amended (the "Code");
(iii) the Securities represent an ownership interest in some or all of the
assets included in the Trust Fund for a Series; or (iv) the Trust Fund relating
to a particular Series of Certificates is treated as a partnership. The
Prospectus Supplement for each Series of Securities will specify how the
Securities will be treated for federal income tax purposes and will discuss
whether a REMIC election, if any, will be made with respect to such Series.
Prior to issuance of each Series of Securities, the Depositor shall file with
the Commission a Form 8-K on behalf of the related Trust Fund containing an
opinion of counsel to the Depositor with respect to the validity of the
information set forth under "Federal Income Tax Consequences" herein and in the
related Prospectus Supplement.
 
TAXATION OF DEBT SECURITIES
 
     General.  If Securities of a Series being issued as Certificates or Notes
are structured as indebtedness secured by the assets of the Trust Fund, assuming
compliance with all provisions of the related documents and applicable law,
Andrews & Kurth L.L.P., special counsel to the Depositor, or other counsel
identified in the Prospectus Supplement is of the opinion that the Securities
will be treated as debt for United States federal income tax purposes, and at
the time such Securities are issued will deliver an opinion generally to that
effect.
 
     Status as Real Property Loans.  Except to the extent otherwise provided in
the related Prospectus Supplement, special counsel to the Depositor identified
in the Prospectus Supplement will have advised the Depositor that: (i)
Securities held by a domestic building and loan association will constitute
"loans...secured by an interest in real property" within the meaning of Code
section 7701(a)(19)(C)(v); (ii) Securities held by a real estate investment
trust will constitute "real estate assets" within the meaning of Code section
856(c)(4)(A) and interest on Securities will be considered "interest on
obligations secured by mortgages on real property or on interests in real
property" within the meaning of Code section 856(c)(3)(B) and (iii) Securities
representing interests in obligations secured by manufactured housing treated as
single family residences under Code Section 25(e)(10) will be considered
interests in "qualified mortgages" as defined in Code Section 860G(a)(3).
 
                                       92

     The Small Business Job Protection Act of 1996, as part of the repeal of the
bad debt reserve method for thrift institutions, repealed the application of
Code Section 593(d) to any taxable year beginning after December 31, 1995.
 
     Interest and Acquisition Discount.  Securities representing regular
interests in a REMIC ("Regular Interest Securities") are generally taxable to
holders in the same manner as evidences of indebtedness issued by the REMIC.
Stated interest on the Regular Interest Securities will be taxable as ordinary
income and taken into account using the accrual method of accounting, regardless
of the Holder's normal accounting method. Interest (other than original issue
discount) on Securities (other than Regular Interest Securities) that are
characterized as indebtedness for federal income tax purposes will be includible
in income by holders thereof in accordance with their usual methods of
accounting. Securities characterized as debt for federal income tax purposes and
Regular Interest Securities will be referred to hereinafter collectively as
"Debt Securities."
 
     Debt Securities that are Compound Interest Securities (generally,
securities all or a portion of the interest on which is not paid currently)
will, and certain of the other Debt Securities may, be issued with "original
issue discount" ("OID"). The following discussion is based in part on the rules
governing OID which are set forth in Sections 1271-1275 of the Code and the
Treasury regulations issued thereunder on February 2, 1994 (the "OID
Regulations"). A holder of Debt Securities should be aware, however, that the
OID Regulations do not adequately address certain issues relevant to prepayable
securities, such as the Debt Securities.
 
     In general, OID, if any, will equal the difference between the stated
redemption price at maturity of a Debt Security and its issue price. A holder of
a Debt Security must include such OID in gross income as ordinary interest
income as it accrues under a method taking into account an economic accrual of
the discount. In general, OID must be included in income in advance of the
receipt of the cash representing that income. The amount of OID on a Debt
Security will be considered to be zero if it is less than a de minimis amount
determined under the Code.
 
     The issue price of a Debt Security is the first price at which a
substantial amount of Debt Securities of that class are sold to the public
(excluding bond houses, brokers, underwriters or wholesalers). If less than a
substantial amount of a particular class of Debt Securities is sold for cash on
or prior to the related closing date, the issue price for such class will be
treated as the fair market value of such class on such closing date. The issue
price of a Debt Security also includes the amount paid by an initial Debt
Security holder for accrued interest that relates to a period prior to the issue
date of the Debt Security. The stated redemption price at maturity of a Debt
Security includes the original principal amount of the Debt Security, but
generally will not include distributions of interest if such distributions
constitute "qualified stated interest."
 
     Under the OID Regulations, qualified stated interest generally means
interest payable at a single fixed rate or qualified variable rate (as described
below) provided that such interest payments are unconditionally payable at
intervals of one year or less during the entire term of the Debt Security. The
OID Regulations state that interest payments are unconditionally payable only if
a late payment or nonpayment is expected to be penalized or reasonable remedies
exist to compel payment. Certain Debt Securities may provide for default
remedies in the event of late payment or nonpayment of interest. The interest on
such Debt Securities will be unconditionally payable and constitute qualified
stated interest, not OID. However, absent clarification of the OID Regulations,
where Debt Securities do not provide for default remedies, the interest payments
will be included in the Debt Security's stated redemption price at maturity and
taxed as OID. Interest is payable at a single fixed rate only if the rate
appropriately takes into account the length of the interval between payments.
Distributions of interest on Debt Securities with respect to which deferred
interest will accrue, will not constitute qualified stated interest payments, in
which case the stated redemption price at maturity of such Debt Securities
includes all distributions of interest as well as principal thereon. Where the
interval between the issue date and the first Distribution Date on a Debt
Security is either longer or shorter than the interval between subsequent
Distribution Dates, all or part of the interest foregone, in the case of the
longer interval, and all of the additional interest, in the case of the shorter
interval, will be included in the stated redemption price at maturity and tested
under the de minimis rule described below. In the case of a Debt Security with a
 
                                       93
<PAGE>   95
 
long first period which has non-de minimis OID, all stated interest in excess of
interest payable at the effective interest rate for the long first period will
be included in the stated redemption price at maturity and the Debt Security
will generally have OID. Holders of Debt Securities should consult their own tax
advisors to determine the issue price and stated redemption price at maturity of
a Debt Security.
 
     Under the de minimis rule OID on a Debt Security will be considered to be
zero if such OID is less than 0.25% of the stated redemption price at maturity
of the Debt Security multiplied by the weighted average maturity of the Debt
Security. For this purpose, the weighted average maturity of the Debt Security
is computed as the sum of the amounts determined by multiplying the number of
full years (i.e., rounding down partial years) from the issue date until each
distribution in reduction of stated redemption price at maturity is scheduled to
be made by a fraction, the numerator of which is the amount of each distribution
included in the stated redemption price at maturity of the Debt Security and the
denominator of which is the stated redemption price at maturity of the Debt
Security. Holders generally must report de minimis OID pro rata as principal
payments are received, and such income will be capital gain if the Debt Security
is held as a capital asset. However, accrual method holders may elect to accrue
all de minimis OID as well as market discount under a constant interest method.
 
     Debt Securities may provide for interest based on a qualified variable
rate. Under the OID Regulations, interest is treated as payable at a qualified
variable rate and not as contingent interest if, generally, (i) such interest is
unconditionally payable at least annually at a "current value" of the index,
(ii) the issue price of the debt instrument does not exceed the total
noncontingent principal payments, (iii) interest is based on a "qualified
floating rate," an "objective rate," or a combination of "qualified floating
rates" that do not operate in a manner that significantly accelerates or defers
interest payments on such Debt Security and (iv) the principal payments are not
contingent. In the case of Compound Interest Securities, certain Interest
Weighted Securities (as defined herein), and certain of the other Debt
Securities, none of the payments under the instrument will be considered
qualified stated interest, and thus the aggregate amount of all payments will be
included in the stated redemption price.
 
     The Internal Revenue Services (the "IRS") recently issued final regulations
(the "Contingent Regulations") governing the calculation of OID on instruments
having contingent interest payments. The Contingent Regulations specifically do
not apply for purposes of calculating OID on debt instruments subject to Code
Section 1272(a)(6), such as the Debt Securities. Additionally, the OID
Regulations do not contain provisions specifically interpreting Code Section
1272(a)(6). Until the Treasury issues guidance to the contrary, the Trustee
intends to base its computation on Code Section 1272(a)(6) and the OID
Regulations as described in this Prospectus. However, because no regulatory
guidance currently exists under Code Section 1272(a)(6), there can be no
assurance that such methodology represents the correct manner of calculating
OID.
 
     The holder of a Debt Security issued with OID must include in gross income,
for all days during its taxable year on which it holds such Debt Security, the
sum of the "daily portions" of such original issue discount. The daily portion
of OID includible in income by a holder will be computed by allocating to each
day during a taxable year a pro rata portion of the original issue discount that
accrued during the relevant accrual period. In the case of a Debt Security that
is not a Regular Interest Security and the principal payments on which are not
subject to acceleration resulting from prepayments on the Trust Fund Accounts,
the amount of OID for an accrual period (generally the period over which
interest accrues on the debt instrument) will equal the product of the yield to
maturity of the Debt Security and the adjusted issue price of the Debt Security
on the first day of such accrual period, reduced by any payments of qualified
stated interest allocable to such accrual period. The adjusted issue price of a
Debt Security on the first day of an accrual period is the sum of the issue
price of the Debt Security plus prior accruals of OID, reduced by the total
payments made with respect to such Debt Security on or before the first day of
such accrual period, other than qualified stated interest payments.
 
     The amount of OID to be included in income by a holder of a debt
instrument, such as certain classes of the Debt Securities, that is subject to
acceleration due to prepayments on other debt obligations securing such
instruments (a "Pay-Through Security"), is computed by taking into account the
anticipated rate of prepayments assumed in pricing the debt instrument (the
"Prepayment Assumption"). The amount of OID
 
                                       94
<PAGE>   96
 
that will accrue during an accrual period on a Pay-Through Security is the
excess (if any) of the sum of (a) the present value of all payments remaining to
be made on the Pay-Through Security as of the close of the accrual period and
(b) the payments during the accrual period of amounts included in the stated
redemption price at maturity of the Pay-Through Security, over the adjusted
issue price of the Pay-Through Security at the beginning of the accrual period.
The present value of the remaining payments is to be determined on the basis of
three factors: (i) the original yield to maturity of the Pay-Through Security
(determined on the basis of compounding at the end of each accrual period and
properly adjusted for the length of the accrual period), (ii) events which have
occurred before the end of the accrual period and (iii) 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 OID
required to be included in income by a holder of a Pay-Through Security to take
into account prepayments with respect to the Loans at a rate that exceeds the
Prepayment Assumption, and to decrease (but not below zero for any period) the
portions of original issue discount required to be included in income by a
holder of a Pay-Through Security to take into account prepayments with respect
to the Loans at a rate that is slower than the Prepayment Assumption. Although
original issue discount will be reported to holders of Pay-Through Securities
based on the Prepayment Assumption, no representation is made to holders of
Pay-Through Securities that Loans will be prepaid at that rate or at any other
rate.
 
     The Depositor may adjust the accrual of OID on a class of Regular Interest
Securities (or other regular interests in a REMIC) in a manner that it believes
to be appropriate, to take account of realized losses on the Loans, although the
OID Regulations do not provide for such adjustments. If the IRS were to require
that OID be accrued without such adjustments, the rate of accrual of OID for a
class of Regular Interest Securities could increase.
 
     Certain classes of Regular Interest Securities may represent more than one
class of REMIC regular interests. Unless otherwise provided in the related
Prospectus Supplement, the Trustee intends, based on the OID Regulations, to
calculate OID on such Securities as if, solely for the purposes of computing
OID, the separate regular interests were a single debt instrument.
 
     A subsequent holder of a Debt Security will also be required to include OID
in gross income, but such a holder who purchases such Debt Security for an
amount that exceeds its adjusted issue price will be entitled (as will an
initial holder who pays more than a Debt Security's issue price) to offset such
OID by comparable economic accruals of portions of such excess.
 
     Effects of Defaults and Delinquencies.  Holders of Securities will be
required to report income with respect to the related Securities under an
accrual method without giving effect to delays and reductions in distributions
attributable to a default or delinquency on the Trust Fund Assets, except
possibly to the extent that it can be established that such amounts are
uncollectible. As a result, the amount of income (including OID) reported by a
holder of such a Security in any period could significantly exceed the amount of
cash distributed to such holder in that period. The holder will eventually be
allowed a loss (or will be allowed to report a lesser amount of income) to the
extent that the aggregate amount of distributions on the Securities is deducted
as a result of a Trust Fund Asset default. However, the timing and character of
such losses or reductions in income are uncertain and, accordingly, holders of
Securities should consult their own tax advisors on this point.
 
     Interest Weighted Securities.  It is not clear how income should be accrued
with respect to Regular Interest Securities or Stripped Securities (as defined
under "-- Tax Status as a Grantor Trust -- General" herein) the payments on
which consist solely or primarily of a specified portion of the interest
payments on qualified mortgages held by the REMIC or on Loans underlying
Pass-Through Securities ("Interest Weighted Securities"). The Depositor intends
to take the position that all of the income derived from an Interest Weighted
Security should be treated as OID and that the amount and rate of accrual of
such OID should be calculated by treating the Interest Weighted Security as a
Compound Interest Security. However, in the case of Interest Weighted Securities
that are entitled to some payments of principal and that are Regular Interest
Securities the IRS could assert that income derived from an Interest Weighted
Security should be calculated as if the Security were a security purchased at a
premium equal to the excess of the price paid by
 
                                       95
<PAGE>   97
 
such holder for such Security over its stated principal amount, if any. Under
this approach, a holder would be entitled to amortize such premium only if it
has in effect an election under Section 171 of the Code with respect to all
taxable debt instruments held by such holder, as described below. Alternatively,
the IRS could assert that an Interest Weighted Security should be taxable under
the rules governing bonds issued with contingent payments. Such treatment may be
more likely in the case of Interest Weighted Securities that are Stripped
Securities as described below. See "-- Tax Status as a Grantor Trust -- Discount
or Premium on Pass-Through Securities."
 
     Variable Rate Debt Securities.  In the case of Debt Securities bearing
interest at a rate that varies directly, according to a fixed formula, with an
objective index, it appears that (i) the yield to maturity of such Debt
Securities and (ii) in the case of Pay-Through Securities, the present value of
all payments remaining to be made on such Debt Securities, should be calculated
as if the interest index remained at its value as of the issue date of such
Securities. Because the proper method of adjusting accruals of OID on a variable
rate Debt Security is uncertain, holders of variable rate Debt Securities should
consult their own tax advisers regarding the appropriate treatment of such
Securities for federal income tax purposes.
 
     Market Discount.  A purchaser of a Security may be subject to the market
discount rules of Sections 1276-1278 of the Code. A holder of a Debt Security
that acquires a Debt Security with more than a prescribed de minimis amount of
"market discount" (generally, the excess of the principal amount of the Debt
Security over the purchaser's purchase price) will be required to include
accrued market discount in income as ordinary income in each month, but limited
to an amount not exceeding the principal payments on the Debt Security received
in that month and, if the Securities are sold, the gain realized. Such market
discount would accrue in a manner to be provided in Treasury regulations but,
until such regulations are issued, such market discount would in general accrue
either (i) on the basis of a constant yield (in the case of a Pay-Through
Security, taking into account a prepayment assumption) or (ii) in the ratio of
(a) in the case of Securities (or in the case of a Pass-Through Security, as set
forth below, the Loans underlying such Security) not originally issued with
original issue discount, stated interest payable in the relevant period to total
stated interest remaining to be paid at the beginning of the period or (b) in
the case of Securities (or, in the case of a Pass-Through Security, as described
below, the Loans underlying such Security) originally issued at a discount, OID
in the relevant period to total OID remaining to be paid.
 
     Section 1277 of the Code provides that, regardless of the origination date
of the Debt Security (or, in the case of a Pass-Through Security, the Loans),
the excess of interest paid or accrued to purchase or carry a Security (or, in
the case of a Pass-Through Security, as described below, the underlying Loans)
with market discount over interest received on such Security is allowed as a
current deduction only to the extent such excess is greater than the market
discount that accrued during the taxable year in which such interest expense was
incurred. In general, the deferred portion of any interest expense will be
deductible when such market discount is included in income, including upon the
sale, disposition, or repayment of the Security (or in the case of a
Pass-Through Security, an underlying Loan). A holder may elect to include market
discount in income currently as it accrues, on all market discount obligations
acquired by such holder during the taxable year such election is made and
thereafter, in which case the interest deferral rule will not apply.
 
     Premium.  A holder who purchases a Debt Security (other than an Interest
Weighted Security to the extent described above) at a cost greater than its
stated redemption price at maturity, generally will be considered to have
purchased the Security at a premium, which it may elect to amortize as an offset
to interest income on such Security (and not as a separate deduction item) on a
constant yield method. Although no regulations addressing the computation of
premium accrual on securities similar to the Securities have been issued, the
legislative history of the Tax Reform Act of 1986 (the "1986 Act") indicates
that premium is to be accrued in the same manner as market discount.
Accordingly, it appears that the accrual of premium on a class of Pay-Through
Securities will be calculated using the prepayment assumption used in pricing
such class. If a holder of a Debt Security makes an election to amortize premium
on a Debt Security, such election will apply to all taxable debt instruments
(including all REMIC regular interests and all pass-through certificates
representing ownership interests in a trust holding debt obligations) held by
the holder at the beginning of the taxable year in which the election is made,
and to all taxable debt instruments acquired thereafter by such holder, and will
be irrevocable without the consent of the IRS. Purchasers who pay a premium for
the
 
                                       96
<PAGE>   98
 
Securities should consult their tax advisers regarding the election to amortize
premium and the method to be employed.
 
     The IRS has issued regulations (the "Amortizable Bond Premium Regulations")
dealing with amortizable bond premium. These regulations specifically do not
apply to prepayable debt instruments subject to Code Section 1272(a)(6) such as
the Securities. Absent further guidance from the IRS, the Trustee intends to
account for amortizable bond premium in the manner described above. Prospective
purchasers of the Securities should consult their tax advisors regarding the
possible application of the Amortizable Bond Premium Regulations.
 
     Election to Treat All Interest as Original Issue Discount.  The OID
Regulations permit a holder of a Debt Security to elect to accrue all interest,
discount (including de minimis market or original issue discount) and premium in
income as interest, based on a constant yield method for Debt Securities
acquired on or after April 4, 1994. If such an election were to be made with
respect to a Debt Security with market discount, the holder of the Debt Security
would be deemed to have made an election to include in income currently market
discount with respect to all other debt instruments having market discount that
such holder of the Debt Security acquires during the year of the election or
thereafter. Similarly, a holder of a Debt Security that makes this election for
a Debt Security that is acquired at a premium will be deemed to have made an
election to amortize bond premium with respect to all debt instruments having
amortizable bond premium that such holder owns or acquires. The election to
accrue interest, discount and premium on a constant yield method with respect to
a Debt Security is irrevocable.
 
TAXATION OF THE REMIC AND ITS HOLDERS
 
     General.  If a REMIC election is made with respect to a Series of
Securities, then upon the issuance of those Securities, assuming such election
is properly made, the provisions of the applicable Agreements are compiled with,
and the statutory and regulatory requirements are satisfied, Andrews & Kurth
L.L.P., special counsel to the Depositor, or other counsel identified in the
Prospectus Supplement is of the opinion that the arrangement by which the
Securities of that Series are issued will be treated as a REMIC and at the time
the Securities are issued will deliver an opinion generally to that effect and
to the effect that the Securities designated as "regular interests" in the REMIC
will be regular interests in a REMIC and will be treated as indebtedness issued
by the REMIC, and that the Securities designated as the sole class of "residual
interests" in the REMIC will be treated as the "residual interest" in the REMIC
for United States federal income tax purposes for as long as all of the
provisions of the applicable Agreement are complied with and the statutory and
regulatory requirements are satisfied. Securities will be designated as "Regular
Interests" or "Residual Interests" in a REMIC, as specified in the related
Prospectus Supplement.
 
     Except to the extent specified otherwise in a Prospectus Supplement, if a
REMIC election is made with respect to a Series of Securities, (i) Securities
held by a domestic building and loan association will constitute "a regular or a
residual interest in a REMIC" within the meaning of Code Section
7701(a)(19)(C)(xi) (assuming that at least 95% of the REMIC's assets consist of
cash, government securities, "loans secured by an interest in real property,"
and other types of assets described in Code Section 7701(a)(19)(C)); and (ii)
Securities held by a real estate investment trust will constitute "real estate
assets" within the meaning of Code Section 856(c)(5)(B), and income with respect
to the Securities will be considered "interest on obligations secured by
mortgages on real property or on interests in real property" within the meaning
of Code Section 856(c)(3)(B) (assuming, for both purposes, that at least 95% of
the REMIC's assets are qualifying assets), and (iii) effective September 1,
1997, Regular Interest Securities held by a financial asset securitization
investment trust (a "FASIT") will qualify for treatment as "permitted assets"
within the meaning of section 860L(c)(1)(G) of the Code. If less than 95% of the
REMIC's assets consist of assets described in (i) or (ii) above, then a Security
will qualify for the tax treatment described in (i) or (ii) in the proportion
that such REMIC assets are qualifying assets.
 
     Status of Manufactured Housing Contracts.  The federal income tax
regulations relating to a REMIC (the "REMIC Regulations") provide that
obligations secured by interests in manufactured housing that
 
                                       97
<PAGE>   99
 
qualify as "single family residences" within the meaning of Code Section
25(e)(10) may be treated as "qualified mortgages" of the REMIC.
 
     Under Section 25(e)(10), 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 a kind of customarily used at
a fixed location.
 
     The Small Business Job Protection Act of 1996, as part of the repeal of the
bad debt reserve method for thrift institutions, repealed the application of
Code section 593(d) to any taxable year beginning after December 31, 1995.
 
REMIC EXPENSES; SINGLE CLASS REMICS
 
     As a general rule, all of the expenses of a REMIC will be taken into
account by holders of the Residual Interest Securities. In the case of a "single
class REMIC," however, the expenses will be allocated, under Treasury
regulations, among the holders of the Regular Interest Securities and the
holders of the Residual Interest Securities on a daily basis in proportion to
the relative amounts of income accruing to each holder of a Residual Interest
Security or Regular Interest Security on that day. In the case of a holder of a
Regular Interest Security who is an individual or a "pass-through interest
holder" (including certain pass-through entities but not including real estate
investment trusts), such expenses will be deductible only to the extent that
such expenses, plus other "miscellaneous itemized deductions" of the holder of a
Regular Interest Security, exceed 2% of such holder's adjusted gross income. In
addition, for taxable years beginning after December 31, 1990, the amount of
itemized deductions otherwise allowable for the taxable year for an individual
whose adjusted gross income exceeds the applicable amount (which amount will be
adjusted for inflation for taxable years beginning after 1990) will be reduced
by the lesser of (i) 3% of the excess of adjusted gross income over the
applicable amount, or (ii) 80% of the amount of itemized deductions otherwise
allowable for such taxable year. The reduction or disallowance of this deduction
may have a significant impact on the yield of the Regular Interest Security to
such a holder. In general terms, a single class REMIC is one that either (i)
would qualify, under existing Treasury regulations, as a grantor trust if it
were not a REMIC (treating all interests as ownership interests, even if they
would be classified as debt for federal income tax purposes) or (ii) is similar
to such a trust and which is structured with the principal purpose of avoiding
the single class REMIC rules. Unless otherwise specified in the related
Prospectus Supplement, the expenses of the REMIC will be allocated to holders of
the related Residual Interest Securities.
 
TAXATION OF THE REMIC
 
     General.  Although a REMIC is a separate entity for federal income tax
purposes, a REMIC is not generally subject to entity-level tax. Rather, the
taxable income or net loss of a REMIC is taken into account by the holders of
residual interests. As described above, the regular interests are generally
taxable as debt of the REMIC.
 
     Calculation of REMIC Income.  The taxable income or net loss of a REMIC is
determined under an accrual method of accounting and in the same manner as in
the case of an individual, with certain adjustments. In general, the taxable
income or net loss will be the difference between (i) the gross income produced
by the REMIC's assets, including stated interest and any original issue discount
or market discount on loans and other assets, and (ii) deductions, including
stated interest and original issue discount accrued on Regular Interest
Securities, amortization of any premium with respect to Loans, and servicing
fees and other expenses of the REMIC. A holder of a Residual Interest Security
that is an individual or a "pass-through interest holder" (including certain
pass-through entities, but not including real estate investment trusts) will be
unable to deduct servicing fees payable on the loans or other administrative
expenses of the REMIC for a given taxable year, to the extent that such
expenses, when aggregated with such holder's other miscellaneous itemized
deductions for that year, do not exceed two percent of such holder's adjusted
gross income.
 
     For purposes of computing its taxable income or net loss, the REMIC should
have an initial aggregate tax basis in its assets equal to the aggregate fair
market value of the regular interests and the residual interests on
 
                                       98
<PAGE>   100
 
the startup day (generally, the day that the interests are issued) (the "Startup
Day"). That aggregate basis will be allocated among the assets of the REMIC in
proportion to their respective fair market values.
 
     The OID provisions of the Code apply to loans of individuals originated on
or after March 2, 1984, and the market discount provisions apply to loans
originated after July 18, 1984. Subject to possible application of the de
minimis rules, the method of accrual by the REMIC of OID income on such loans
will be equivalent to the method under which holders of Pay-Through Securities
accrue original issue discount (i.e., under the constant yield method taking
into account the Prepayment Assumption). The REMIC will deduct OID on the
Regular Interest Securities in the same manner that the holders of the Regular
Interest Securities include such discount in income, but without regard to the
de minimis rules. See "Federal Income Tax Consequences -- General" above.
However, a REMIC that acquires loans at a market discount must include such
market discount in income currently, as it accrues, on a constant interest
basis.
 
     To the extent that the REMIC's basis allocable to loans that it holds
exceeds their principal amounts, the resulting premium, if attributable to
mortgages originated after September 27, 1985, will be amortized over the life
of the loans (taking into account the Prepayment Assumption) on a constant yield
method. Although the law is somewhat unclear regarding recovery of premium
attributable to loans originated on or before such date, it is possible that
such premium may be recovered in proportion to payments of loan principal.
 
     Prohibited Transactions and Contributions Tax.  The REMIC will be subject
to a 100% tax on any net income derived from a "prohibited transaction." For
this purpose, net income will be calculated without taking into account any
losses from prohibited transactions or any deductions attributable to any
prohibited transaction that resulted in a loss. In general, prohibited
transactions include: (i) subject to limited exceptions, the sale or other
disposition of any qualified mortgage transferred to the REMIC; (ii) subject to
a limited exception, the sale or other disposition of a cash flow investment;
(iii) the receipt of any income from assets not permitted to be held by the
REMIC pursuant to the Code; or (iv) the receipt of any fees or other
compensation for services rendered by the REMIC. It is anticipated that a REMIC
will not engage in any prohibited transactions in which it would recognize a
material amount of net income. In addition, subject to a number of exceptions, a
tax is imposed at the rate of 100% on amounts contributed to a REMIC after the
close of the three-month period beginning on the Startup Day. The holders of
Residual Interest Securities will generally be responsible for the payment of
any such taxes imposed on the REMIC. To the extent not paid by such holders or
otherwise, however, such taxes will be paid out of the Trust Fund and will be
allocated pro rata to all outstanding classes of Securities of such REMIC.
 
TAXATION OF HOLDERS OF RESIDUAL INTEREST SECURITIES
 
     The holder of a Security representing a residual interest (a "Residual
Interest Security") will take into account the "daily portion" of the taxable
income or net loss of the REMIC for each day during the taxable year on which
such holder held the Residual Interest Security. The daily portion is determined
by allocating to each day in any calendar quarter its ratable portion of the
taxable income or net loss of the REMIC for such quarter, and by allocating that
amount among the holders (on such day) of the Residual Interest Securities in
proportion to their respective holdings on such day.
 
     The holder of a Residual Interest Security must report its proportionate
share of the taxable income of the REMIC whether or not it receives cash
distributions from the REMIC attributable to such income or loss. The reporting
of taxable income without corresponding distributions could occur, for example,
in certain REMIC issues in which the loans held by the REMIC were issued or
acquired at a discount, since mortgage prepayments cause recognition of discount
income, while the corresponding portion of the prepayment could be used in whole
or in part to make principal payments on REMIC Regular Interests issued without
any discount or at an insubstantial discount (if this occurs, it is likely that
cash distributions will exceed taxable income in later years). Taxable income
may also be greater in earlier years of certain REMIC issues as a result of the
fact that interest expense deductions, as a percentage of outstanding principal
on REMIC Regular Interest Securities, will typically increase over time as lower
yielding Securities are paid, whereas interest income with respect to loans will
generally remain constant over time as a percentage of loan principal.
 
                                       99
<PAGE>   101
 
     In any event, because the holder of a residual interest is taxed on the net
income of the REMIC, the taxable income derived from a Residual Interest
Security in a given taxable year will not be equal to the taxable income
associated with investment in a corporate bond or stripped instrument having
similar cash flow characteristics and pretax yield. Therefore, the after-tax
yield on the Residual Interest Security may be less than that of such a bond or
instrument.
 
     Limitation on Losses.  The amount of the REMIC's net loss that a holder may
take into account currently is limited to the holder's adjusted basis at the end
of the calendar quarter in which such loss arises. A holder's basis in a
Residual Interest Security will initially equal such holder's purchase price,
and will subsequently be increased by the amount of the REMIC's taxable income
allocated to the holder, and decreased (but not below zero) by the amount of
distributions made and the amount of the REMIC's net loss allocated to the
holder. Any disallowed loss may be carried forward indefinitely, but may be used
only to offset income of the REMIC generated by the same REMIC. The ability of
holders of Residual Interest Securities to deduct net losses may be subject to
additional limitations under the Code, as to which such holders should consult
their tax advisers.
 
     Distributions.  Distributions on a Residual Interest Security (whether at
their scheduled times or as a result of prepayments) will generally not result
in any additional taxable income or loss to a holder of a Residual Interest
Security. If the amount of such payment exceeds a holder's adjusted basis in the
Residual Interest Security, however, the holder will recognize gain (treated as
gain from the sale of the Residual Interest Security) to the extent of such
excess.
 
     Sale or Exchange.  A holder of a Residual Interest Security will recognize
gain or loss on the sale or exchange of a Residual Interest Security equal to
the difference, if any, between the amount realized and such holder's adjusted
basis in the Residual Interest Security at the time of such sale or exchange.
Except to the extent provided in regulations, which have not yet been issued,
any loss upon disposition of a Residual Interest Security will be disallowed if
the selling holder acquires any residual interest in a REMIC or similar mortgage
pool within six months before or after such disposition.
 
     Excess Inclusions.  The portion of the REMIC taxable income of a holder of
a Residual Interest Security consisting of "excess inclusion" income may not be
offset by other deductions or losses, including net operating losses, on such
holder's federal income tax return. Further, if the holder of a Residual
Interest Security is an organization subject to the tax on unrelated business
income imposed by Code Section 511, such holder's excess inclusion income will
be treated as unrelated business taxable income of such holder. In addition,
under Treasury regulations yet to be issued, if a real estate investment trust,
a regulated investment company, a common trust fund, or certain cooperatives
were to own a Residual Interest Security, a portion of dividends (or other
distributions) paid by the real estate investment trust (or other entity) would
be treated as excess inclusion income. If a Residual Security is owned by a
foreign person, excess inclusion income is subject to tax at a rate of 30% which
may not be reduced by treaty, is not eligible for treatment as "portfolio
interest" and is subject to certain additional limitations. See "-- Tax
Treatment of Foreign Investors." 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 on 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 cannot be less than
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,
1995, unless a residual holder elects to have such rules apply only to tax years
beginning after August 20, 1996.
 
                                       100
<PAGE>   102
 
     The excess inclusion portion of a REMIC's income is generally equal to the
excess, if any, of REMIC taxable income for the quarterly period allocable to a
Residual Interest Security, over the daily accruals for such quarterly period of
(i) 120% of the long term applicable federal rate on the Startup Day multiplied
by (ii) the adjusted issue price of such Residual Interest Security at the
beginning of such quarterly period. The adjusted issue price of a Residual
Interest Security at the beginning of each calendar quarter will equal its issue
price (calculated in a manner analogous to the determination of the issue price
of a Regular Interest Security), increased by the aggregate of the daily
accruals for prior calendar quarters, and decreased (but not below zero) by the
amount of loss allocated to a holder and the amount of distributions made on the
Residual Interest Security before the beginning of the quarter. The long-term
federal rate, which is announced monthly by the Treasury Department, is an
interest rate that is based on the average market yield of outstanding
marketable obligations of the United States government having remaining
maturities in excess of nine years.
 
     Under the REMIC Regulations, in certain circumstances, transfers of
Residual Interest Securities may be disregarded. See "-- Restrictions on
Ownership and Transfer of Residual Interest Securities" and "-- Tax Treatment of
Foreign Investors" below.
 
     Restrictions on Ownership and Transfer of Residual Interest Securities.  As
a condition to qualification as a REMIC, reasonable arrangements must be made to
prevent the ownership of a REMIC residual interest by any "Disqualified
Organization." Disqualified Organizations include the United States, any State
or political subdivision thereof, any foreign government, any international
organization, or any agency or instrumentality of any of the foregoing, a rural
electric or telephone cooperative described in Section 1381(a)(2)(C) of the
Code, or any entity exempt from the tax imposed by Sections 1-1399 of the Code,
if such entity is not subject to tax on its unrelated business income.
Accordingly, the applicable Agreement will prohibit Disqualified Organizations
from owning a Residual Interest Security. In addition, no transfer of a Residual
Interest Security will be permitted unless the proposed transferee shall have
furnished to the Trustee an affidavit representing and warranting that it is
neither a Disqualified Organization nor an agent or nominee acting on behalf of
a Disqualified Organization.
 
     If a Residual Interest Security is transferred to a Disqualified
Organization after March 31, 1988 (in violation of the restrictions set forth
above), a substantial tax will be imposed on the transferor of such Residual
Interest Security at the time of the transfer. In addition, if a Disqualified
Organization holds an interest in a pass-through entity after March 31, 1988
(including, among others, a partnership, trust, real estate investment trust,
regulated investment company, or any person holding as nominee), that owns a
Residual Interest Security, the pass-through entity will be required to pay an
annual tax on its allocable share of the excess inclusion income of the REMIC.
 
     Under the REMIC Regulations, if a Residual Interest Security is a
"noneconomic residual interest," as described below, a transfer of a Residual
Interest Security to a United States person will be disregarded for all Federal
tax purposes unless no significant purpose of the transfer was to impede the
assessment or collection of tax. A Residual Interest Security is a "noneconomic
residual interest" unless, at the time of the transfer (i) the present value of
the expected future distributions on the Residual Interest Security at least
equals the product of the present value of the anticipated excess inclusions and
the highest rate of tax for the year in which the transfer occurs, and (ii) the
transferor reasonably expects that the transferee will receive distributions
from the REMIC at or after the time at which the taxes accrue on the anticipated
excess inclusions in an amount sufficient to satisfy the accrued taxes. If a
transfer of a Residual Interest Security is disregarded, the transferor would be
liable for any Federal income tax imposed upon taxable income derived by the
transferee from the REMIC. The REMIC Regulations provide no guidance as to how
to determine if a significant purpose of a transfer is to impede the assessment
or collection of tax. A similar type of limitation exists with respect to
certain transfers of residual interests by foreign persons to United States
persons. See "-- Tax Treatment of Foreign Investors."
 
     Mark to Market Rules.  Under IRS regulations a REMIC Residual Interest
Security acquired after January 3, 1995 cannot be marked-to-market.

ADMINISTRATIVE MATTERS
 
     The REMIC's books must be maintained on a calendar year basis and the REMIC
must file an annual federal income tax return. The REMIC will also be subject to
the procedural and administrative rules of the Code applicable to partnerships,
including the determination of any adjustments to, among other things, items of
REMIC income, gain, loss, deduction, or credit, by the IRS in a unified
administrative proceeding.
 
TAX STATUS AS A GRANTOR TRUST
 
     General.  If the related Prospectus Supplement does not specify that an
election will be made to treat the assets of the Trust Fund as one or more
REMICs or to treat the Trust Fund as a partnership, then Depositor will have
structured the Trust Fund (or the portion of its assets for which a REMIC
election will not be made) to be classified for United States federal income tax
purposes as a grantor trust under Subpart E, Part I of Subchapter J of the Code,
in which case, Andrews & Kurth L.L.P., special counsel to the Depositor, or
other counsel identified in the Prospectus Supplement, is of the opinion that,
assuming compliance with the Agreements and with applicable law, such
arrangement will not be treated as an association taxable as a corporation for
United States federal income tax purposes, and the Securities will be treated as
representing ownership interests in the related Trust Fund assets (the
Securities of such Series, "Pass-Through Securities") and at the time such
Pass-Through Securities are issued, special counsel to the Depositor will
deliver an opinion generally to that effect. In some Series there will be no
separation of the principal and interest payments on the Loans. In such
circumstances, a holder of a Pass-Through Security will be considered to have
purchased a pro rata undivided interest in each of the Loans. In other cases
("Stripped Securities"), sale of the Securities will produce a separation in the
ownership of all or a portion of the principal payments from all or a portion of
the interest payments on the Loans.
 
     Each holder of a Pass-Through Security must report on its federal income
tax return its share of the gross income derived from the Loans (not reduced by
the amount payable as fees to the Trustee and the Servicer and similar fees
(collectively, the "Servicing Fee"), at the same time and in the same manner as
such items would have been reported under the holder's tax accounting method had
it held its interest in the Loans directly, received directly its share of the
amounts received with respect to the Loans, and paid directly its share of the
Servicing Fees. In the case of Pass-Through Securities other than Stripped
Securities, such income will consist of a pro rata share of all of the income
derived from all of the Loans and, in the case of Stripped Securities, such
income will consist of a pro rata share of the income derived from each stripped
bond or stripped coupon in which the holder owns an interest. The holder of a
Security will generally be entitled to deduct such Servicing Fees under Section
162 or Section 212 of the Code to the extent that such Servicing Fees represent
"reasonable" compensation for the services rendered by the Trustee and the
Servicer (or third parties that are compensated for the performance of
services). In the case of a noncorporate holder, however, Servicing Fees (to the
extent not otherwise disallowed, e.g., because they exceed reasonable
compensation) will be deductible in computing such holder's regular tax
liability only to the extent that such fees, when added to other miscellaneous
itemized deductions, exceed 2% of adjusted gross income and may not be
deductible to any extent in computing such holder's alternative minimum tax
liability. In addition, for taxable years beginning after December 31, 1990, the
amount of itemized deductions otherwise allowable for the taxable year for an
individual whose adjusted gross income exceeds the applicable amount (which
amount will be adjusted for inflation in taxable years beginning after 1990)
will be reduced by the lesser of (i) 3% of the excess of adjusted gross income
over the applicable amount or (ii) 80% of the amount of itemized deductions
otherwise allowable for such taxable year.
 
     Discount or Premium on Pass-Through Securities.  The holder's purchase
price of a Pass-Through Security is to be allocated among the Loans in
proportion to their fair market values, determined as of the time of purchase of
the Securities. In the typical case, the Trustee (to the extent necessary to
fulfill its reporting obligations) will treat each Loan as having a fair market
value proportional to the share of the aggregate principal balances of all of
the Loans that it represents, since the Securities, unless otherwise specified
in the related Prospectus Supplement, will have a relatively uniform interest
rate and other common characteristics. To the extent that the portion of the
purchase price of a Pass-Through Security allocated to a Loan (other than to a
right to receive any accrued interest thereon and any undistributed principal
payments)
 
                                       102
<PAGE>   104
 
is less than or greater than the portion of the principal balance of the Loan
allocable to the Security, the interest in the Loan allocable to the
Pass-Through Security will be deemed to have been acquired at a discount or
premium, respectively.
 
     The treatment of any discount will depend on whether the discount
represents OID or market discount. In the case of a Loan with OID in excess of a
prescribed de minimis amount or a Stripped Security, a holder of a Security will
be required to report as interest income in each taxable year its share of the
amount of OID that accrues during that year in the manner described above. OID
with respect to a Loan could arise, for example, by virtue of the financing of
points by the originator of the Loan, or by virtue of the charging of points by
the originator of the Loan in an amount greater than a statutory de minimis
exception, in circumstances under which the points are not currently deductible
pursuant to applicable Code provisions. Any market discount or premium on a Loan
will be includible in income, generally in the manner described above, except
that in the case of Pass-Through Securities, market discount is calculated with
respect to the Loans underlying the Security, rather than with respect to the
Security. A holder of a Security that acquires an interest in a Loan originated
after July 18, 1984 with more than a de minimis amount of market discount
(generally, the excess of the principal amount of the Loan over the purchaser's
allocable purchase price) will be required to include accrued market discount in
income in the manner set forth above. See "-- Taxation of Debt Securities;
Market Discount" and "-- Premium" above.
 
     In the case of market discount on a Pass-Through Security attributable to
Loans originated on or before July 18, 1984, the holder generally will be
required to allocate the portion of such discount that is allocable to a loan
among the principal payments on the Loan and to include the discount allocable
to each principal payment in ordinary income at the time such principal payment
is made. Such treatment would generally result in discount being included in
income at a slower rate than discount would be required to be included in income
using the method described in the preceding paragraph.
 
     Stripped Securities.  A Stripped Security may represent a right to receive
only a portion of the interest payments on the Loans, a right to receive only
principal payments on the Loans, or a right to receive certain payments of both
interest and principal. Certain Stripped Securities ("Ratio Strip Securities")
may represent a right to receive differing percentages of both the interest and
principal on each Loan. Pursuant to Section 1286 of the Code, the separation of
ownership of the right to receive some or all of the interest payments on an
obligation from ownership of the right to receive some or all of the principal
payments results in the creation of "stripped bonds" with respect to principal
payments and "stripped coupons" with respect to interest payments. Section 1286
of the Code applies the OID rules to stripped bonds and stripped coupons. For
purposes of computing original issue discount, a stripped bond or a stripped
coupon is treated as a debt instrument issued on the date that such stripped
interest is purchased with an issue price equal to its purchase price or, if
more than one stripped interest is purchased, the ratable share of the purchase
price allocable to such stripped interest.
 
     Servicing fees in excess of reasonable servicing fees ("excess servicing")
will be treated under the stripped bond rules. If the excess servicing fee is
less than 100 basis points (i.e., 1% interest on the Loan principal balance) or
the Securities are initially sold with a de minimis discount (assuming no
prepayment assumption is required), any non-de minimis discount arising from a
subsequent transfer of the Securities should be treated as market discount. The
IRS appears to require that reasonable servicing fees be calculated on a Loan by
Loan basis, which could result in some Loans being treated as having more than
100 basis points of interest stripped off.
 
     The Code, OID Regulations and judicial decisions provide no direct guidance
as to how the interest and original issue discount rules are to apply to
Stripped Securities and other Pass-Through Securities. Under the method
described above for Pay-Through Securities (the "Cash Flow Bond Method"), a
prepayment assumption is used and periodic recalculations are made which take
into account with respect to each accrual period the effect of prepayments
during such period. However, the 1986 Act does not, absent Treasury regulations,
appear specifically to cover instruments such as the Stripped Securities which
technically represent ownership interests in the underlying Loans, rather than
being debt instruments "secured by" those loans. Nevertheless, it is believed
that the Cash Flow Bond Method is a reasonable method of reporting
 
                                       103
<PAGE>   105
 
income for such Securities, and it is expected that OID will be reported on that
basis unless otherwise specified in the related Prospectus Supplement. In
applying the calculation to Pass-Through Securities, the Trustee will treat all
payments to be received by a holder with respect to the underlying Loans as
payments on a single installment obligation. The IRS could, however, assert that
original issue discount must be calculated separately for each Loan underlying a
Security.
 
     Under certain circumstances, if the Loans prepay at a rate faster than the
Prepayment Assumption, the use of the Cash Flow Bond Method may accelerate a
holder's recognition of income. If, however, the Loans prepay at a rate slower
than the Prepayment Assumption, in some circumstances the use of this method may
decelerate a holder's recognition of income.
 
     In the case of a Stripped Security that is an Interest Weighted Security,
the Trustee intends, absent contrary authority, to report income to holders of
Securities as OID, in the manner described above for Interest Weighted
Securities.
 
     Possible Alternative Characterizations.  The characterizations of the
Stripped Securities described above are not the only possible interpretations of
the applicable Code provisions. Among other possibilities, the IRS could contend
that (i) in certain Series, each non-Interest Weighted Security is composed of
an unstripped undivided ownership interest in Loans and an installment
obligation consisting of stripped principal payments; (ii) the non-Interest
Weighted Securities are subject to the contingent payment provisions of the
Contingent Regulations; or (iii) each Interest Weighted Stripped Security is
composed of an unstripped undivided ownership interest in Loans and an
installment obligation consisting of stripped interest payments.
 
     Given the variety of alternatives for treatment of the Stripped Securities
and the different federal income tax consequences that result from each
alternative, potential purchasers are urged to consult their own tax advisers
regarding the proper treatment of the Securities for federal income tax
purposes.
 
     Character as Qualifying Loans.  In the case of Stripped Securities, there
is no specific legal authority existing regarding whether the character of the
Securities, for federal income tax purposes, will be the same as the Loans. The
IRS could take the position that the Loans' character is not carried over to the
Securities in such circumstances. Pass-Through Securities will be, and, although
the matter is not free from doubt, Stripped Securities should be, considered to
represent "real estate assets" within the meaning of Section 856(c)(5)(B) of the
Code, and "loans secured by an interest in real property" within the meaning of
Section 7701(a)(19)(C)(v) of the Code; interest income attributable to the
Securities should be considered to represent "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. Reserves or funds underlying the Securities
may cause a proportionate reduction in the above-described qualifying status
categories of Securities.
 
SALE OR EXCHANGE
 
     Subject to the discussion below with respect to Trust Funds as to which a
partnership election is made, a holder's tax basis in its Security is the price
such holder pays for a Security, plus amounts of original issue or market
discount included in income and reduced by any payments received (other than
qualified stated interest payments) and any amortized premium. Gain or loss
recognized on a sale, exchange, or redemption of a Security, measured by the
difference between the amount realized and the Security's basis as so adjusted,
will generally be capital gain or loss, assuming that the Security is held as a
capital asset. In the case of a Security held by a bank, thrift, or similar
institution described in Section 582 of the Code, however, gain or loss realized
on the sale or exchange of a Regular Interest Security will be taxable as
ordinary income or loss. In addition, gain from the disposition of a Regular
Interest Security that might otherwise be capital gain will be treated as
ordinary income to the extent of the excess, if any, of (i) the amount that
would have been includible in the holder's income if the yield on such Regular
Interest Security had equaled 110% of the applicable federal rate as of the
beginning of such holder's holding period, over the amount of ordinary income
actually recognized by the holder with respect to such Regular Interest
Security.

MISCELLANEOUS TAX ASPECTS
 
     Backup Withholding.  Subject to the discussion below with respect to Trust
Funds as to which a partnership election is made, a holder of a Security, other
than a holder of a REMIC Residual Security, may, under certain circumstances, be
subject to "backup withholding" at a rate of 31% with respect to distributions
or the proceeds of a sale of certificates to or through brokers that represent
interest or original issue discount on the Securities. This withholding
generally applies if the holder of a Security (i) fails to furnish the Trustee
with its taxpayer identification number ("TIN"); (ii) furnishes the Trustee an
incorrect TIN; (iii) fails to report properly interest, dividends or other
"reportable payments" as defined in the Code; or (iv) under certain
circumstances, fails to provide the Trustee or such holder's securities broker
with a certified statement, signed under penalty of perjury, that the TIN
provided is its correct number and that the holder is not subject to backup
withholding. Backup withholding will not apply, however, with respect to certain
payments made to holders of Securities, including payments to certain exempt
recipients (such as exempt organizations) and to certain Nonresidents (as
defined below). Holders of Securities should consult their tax advisers as to
their qualification for exemption from backup withholding and the procedure for
obtaining the exemption.
 
     The Trustee will report to the holders of Securities and to the Master
Servicer for each calendar year the amount of any "reportable payments" during
such year and the amount of tax withheld, if any, with respect to payments on
the Securities.
 
TAX TREATMENT OF FOREIGN INVESTORS
 
     Subject to the discussion below with respect to Trust Funds as to which a
partnership election is made, under the Code, unless interest (including OID)
paid on a Security (other than a Residual Interest Security) is considered to be
"effectively connected" with a trade or business conducted in the United States
by a nonresident alien individual, foreign partnership or foreign corporation
("Nonresidents"), such interest will normally qualify as portfolio interest
(except where (i) the recipient is a holder, directly or by attribution, of 10%
or more of the capital or profits interest in the issuer, or (ii) the recipient
is a controlled foreign corporation to which the issuer is a related person) and
will be exempt from federal income tax. Upon receipt of appropriate ownership
statements, the issuer normally will be relieved of obligations to withhold tax
from such interest payments. These provisions supersede the generally applicable
provisions of United States law that would otherwise require the issuer to
withhold at a 30% rate (unless such rate were reduced or eliminated by an
applicable tax treaty) on, among other things, interest and other fixed or
determinable, annual or periodic income paid to Nonresidents. Holders of
Pass-Through Securities and Stripped Securities, including Ratio Strip
Securities, however, may be subject to withholding to the extent that the Loans
were originated on or before July 18, 1984.
 
     Interest and OID of holders of Securities who are foreign persons are not
subject to withholding if they are effectively connected with a United States
business conducted by the holder. They will, however, generally be subject to
the regular United States income tax.
 
     Payments to holders of Residual Interest Securities who are foreign persons
will generally be treated as interest for purposes of the 30% (or lower treaty
rate) United States withholding tax. Holders of Residual Interest Securities
should assume that such income does not qualify for exemption from United States
withholding tax as "portfolio interest." It is clear that, to the extent that a
payment represents a portion of REMIC taxable income that constitutes excess
inclusion income, a holder of a Residual Interest Security will not be entitled
to an exemption from or reduction of the 30% (or lower treaty rate) withholding
tax rule. If the payments are subject to United States withholding tax, they
generally will be taken into account for withholding tax purposes only when paid
or distributed (or when the Residual Interest Security is disposed of). The
Treasury has statutory authority, however, to promulgate regulations which would
require such amounts to be taken into account at an earlier time in order to
prevent the avoidance of tax. Such regulations could, for example, require
withholding prior to the distribution of cash in the case of Residual Interest
Securities that do not have significant value. Under the REMIC Regulations, if a
Residual Interest Security has tax avoidance potential, a transfer of a Residual
Interest Security to a Nonresident will be disregarded for all federal tax
purposes. A Residual Interest Security has tax avoidance potential unless, at
the time of the
 
                                       105
<PAGE>   107
 
transfer the transferor reasonably expects that the REMIC will distribute to the
transferee residual interest holder amounts that will equal at least 30% of each
excess inclusion, and that such amounts will be distributed at or after the time
at which the excess inclusions accrue and not later than the calendar year
following the calendar year of accrual. If a Nonresident transfers a Residual
Interest Security to a United States person, and if the transfer has the effect
of allowing the transferor to avoid tax on accrued excess inclusions, then the
transfer is disregarded and the transferor continues to be treated as the owner
of the Residual Interest Security for purposes of the withholding tax provisions
of the Code. See "-- Taxation of Holders of Residual Interest
Securities -- Excess Inclusions."
 
     Final regulations dealing with withholding tax on income paid to foreign
persons and related matters (the "New Withholding Regulations") were issued by
the Treasury Department on October 6, 1997. The New Withholding Regulations will
generally be effective for payments made after December 31, 1999, subject to
certain transition rules. Prospective Securityholders who are foreign persons
are strongly urged to consult their own tax advisors with respect to the New
Withholding Regulations.
 
TAX CHARACTERIZATION OF THE TRUST FUND AS A PARTNERSHIP
 
     If the related Prospectus Supplement specifies that an election will be
made to treat the Trust Fund as a partnership, pursuant to Agreements upon which
counsel shall conclude that (1) the Trust Fund will not have certain
characteristics necessary for a business trust to be classified as an
association taxable as a corporation and (2) the nature of the income of the
Trust Fund will exempt it from the rule that certain publicly traded
partnerships are taxable as corporations or the issuance of the Securities has
been structured as a private placement under an IRS safe harbor, so that the
Trust Fund will not be characterized as a publicly traded partnership taxable as
a corporation, then assuming compliance with the related Agreement and related
documents and applicable law, Andrews & Kurth L.L.P., special counsel to the
Depositor, or other counsel identified in the Prospectus Supplement, is of the
opinion that the Trust Fund will not be treated as an association (or as a
publicly traded partnership) taxable as a corporation for United States federal
income tax purposes, and upon the issuance of such Securities, will deliver an
opinion generally to that effect. If the Securities are structured as
indebtedness issued by the partnership, special counsel to the Depositor also
will opine that the Securities should be treated as debt for United States
federal income tax purposes, and, if the Securities are structured as equity
interests in the partnership, will opine that the Securities should be treated
as equity interest in the partnership for United States federal income tax
purposes, in each case assuming compliance with the related Agreements and
applicable law.
 
     If the Trust Fund were taxable as a corporation for federal income tax
purposes, the Trust Fund would be subject to corporate income tax on its taxable
income. The Trust Fund's taxable income would include all its income, possibly
reduced by its interest expense on the Notes. Any such corporate income tax
could materially reduce cash available to make payments on the Notes and
distributions on the Certificates, and holders of Certificates could be liable
for any such tax that is unpaid by the Trust Fund.
 
TAX CONSEQUENCES TO HOLDERS OF THE NOTES
 
     Treatment of the Notes as Indebtedness.  In the case of a Trust Fund that
issues Notes intended to be debt for federal income tax purposes, the Trust Fund
will agree, and the holders of Notes will agree by their purchase of Notes, to
treat the Notes as debt for federal income tax purposes. Special counsel to the
Depositor will, except as otherwise provided in the related Prospectus
Supplement, advise the Depositor that the Notes will be classified as debt for
federal income tax purposes. The discussion below assumes this characterization
of the Notes is correct.
 
     OID, Indexed Securities, etc.  The discussion below assumes that all
payments on the Notes are denominated in U.S. dollars, and that the Notes are
not Indexed Securities or Stripped Securities. Moreover, the discussion assumes
that the interest formula for the Notes meets the requirements for "qualified
stated interest" under the OID regulations, and that any OID on the Notes (i.e.,
any excess of the principal amount of the Notes over their issue price) does not
exceed a de minimis amount (i.e., 0.25% of their principal amount multiplied by
the number of full years included in their term), all within the meaning of the
OID
 
                                       106
<PAGE>   108
 
regulations. If these conditions are not satisfied with respect to any given
Series of Notes, additional tax considerations with respect to such Notes will
be disclosed in the applicable Prospectus Supplement.
 
     Interest Income on the Notes.  Based on the above assumptions, except as
discussed in the following paragraph, the Notes will not be considered issued
with OID. The stated interest thereon will be taxable to a holder of a Note as
ordinary interest income when received or accrued in accordance with such
holder's method of tax accounting. Under the OID regulations, a holder of a Note
issued with a de minimis amount of OID must include such OID in income, on a pro
rata basis, as principal payments are made on the Note. It is believed that any
prepayment premium paid as a result of a mandatory redemption will be taxable as
contingent interest when it becomes fixed and unconditionally payable. A
purchaser who buys a Note for more or less than its principal amount will
generally be subject, respectively, to the premium amortization or market
discount rules of the Code.
 
     A holder of a Note that has a fixed maturity date of not more than one year
from the issue date of such Note (a "Short-Term Note") may be subject to special
rules. An accrual basis holder of a Short-Term Note (and certain cash method
holders, including regulated investment companies, as set forth in Section 1281
of the Code) generally would be required to report interest income as interest
accrues on a straight-line basis over the term of each interest period. Other
cash basis holders of a Short-Term Note would, in general, be required to report
interest income as interest is paid (or, if earlier, upon the taxable
disposition of the Short-Term Note). However, a cash basis holder of a
Short-Term Note reporting interest income as it is paid may be required to defer
a portion of any interest expense otherwise deductible on indebtedness incurred
to purchase or carry the Short-Term Note until the taxable disposition of the
Short-Term Note. A cash basis taxpayer may elect under Section 1281 of the Code
to accrue interest income on all nongovernment debt obligations with a term of
one year or less, in which case the taxpayer would include interest on the
Short-Term Note in income as it accrues, but would not be subject to the
interest expense deferral rule referred to in the preceding sentence. Certain
special rules apply if a Short-Term Note is purchased for more or less than its
principal amount.
 
     Sale or Other Disposition.  If a holder of a Note sells a Note, the holder
will recognize gain or loss in an amount equal to the difference between the
amount realized on the sale and the holder's adjusted tax basis in the Note. The
adjusted tax basis of a Note to a particular holder of a Note will equal the
holder's cost for the Note, increased by any market discount, acquisition
discount, OID and gain previously included by such holder in income with respect
to the Note and decreased by the amount of bond premium (if any) previously
amortized and by the amount of principal payments previously received by such
holder with respect to such Note. Any such gain or loss will be capital gain or
loss if the Note was held as a capital asset, except for gain representing
accrued interest and accrued market discount not previously included in income.
Capital losses generally may be used only to offset capital gains.
 
     Foreign Holders.  Interest payments made (or accrued) to a holder of a Note
who is a nonresident alien, foreign corporation or other non-United States
person (a "foreign person") generally will be considered "portfolio interest,"
and generally will not be subject to United States federal income tax and
withholding tax, if the interest is not effectively connected with the conduct
of a trade or business within the United States by the foreign person and the
foreign person (i) is not actually or constructively a "10 percent shareholder"
of the Trust Fund or the Seller (including a holder of 10% of the outstanding
Certificates) or a "controlled foreign corporation" with respect to which the
Trust Fund or the Seller is a "related person" within the meaning of the Code
and (ii) provides the Depositor or other person who is otherwise required to
withhold U.S. tax with respect to the Notes with an appropriate statement (on
Form W-8 or a similar form), signed under penalties of perjury, certifying that
the beneficial owner of the Note is a foreign person and providing the foreign
person's name and address. If a Note is held through a securities clearing
organization or certain other financial institutions, the organization or
institution may provide the relevant signed statement to the withholding agent;
in that case, however, the signed statement must be accompanied by a Form W-8 or
substitute form provided by the foreign person that owns the Note. If such
interest is not portfolio interest, then it will be subject to United States
federal income and withholding tax at a rate of 30 percent, unless reduced or
eliminated pursuant to an applicable tax treaty.
 
                                       107
<PAGE>   109
 
     Any capital gain realized on the sale, redemption, retirement or other
taxable disposition of a Note by a foreign person will be exempt from United
States federal income and withholding tax, provided that (i) such gain is not
effectively connected with the conduct of a trade or business in the United
States by the foreign person and (ii) in the case of an individual foreign
person, the foreign person is not present in the United States for 183 days or
more in the taxable year.
 
     Backup Withholding.  Each holder of a Note (other than an exempt holder
such as a corporation, tax-exempt organization, qualified pension and
profit-sharing trust, individual retirement account or nonresident alien who
provides certification as to status as a nonresident) will be required to
provide, under penalties of perjury, a certificate containing the holder's name,
address, correct federal taxpayer identification number and a statement that the
holder is not subject to backup withholding. Should a nonexempt holder of a Note
fail to provide the required certification, the Trust Fund will be required to
withhold 31 percent of the amount otherwise payable to the holder, and remit the
withheld amount to the IRS as a credit against the holder's federal income tax
liability.
 
     Possible Alternative Treatments of the Notes.  If, contrary to the opinion
of special counsel to the Depositor, the IRS successfully asserted that one or
more of the Notes did not represent debt for federal income tax purposes, the
Notes might be treated as equity interests in the Trust Fund. If so treated, the
Trust Fund might be taxable as a corporation with the adverse consequences
described above (and the taxable corporation would not be able to reduce its
taxable income by deductions for interest expense on Notes recharacterized as
equity). Alternatively, and most likely in the view of special counsel to the
Depositor, the Trust Fund might be treated as a publicly traded partnership that
would not be taxable as a corporation because it would meet certain qualifying
income tests. Nonetheless, treatment of the Notes as equity interests in such a
publicly traded partnership could have adverse tax consequences to certain
holders. For example, income to certain tax-exempt entities (including pension
funds) would be "unrelated business taxable income," income to foreign holders
generally would be subject to U.S. tax and U.S. tax return filing and
withholding requirements, and individual holders might be subject to certain
limitations on their ability to deduct their share of the Trust Fund's expenses.
 
TAX CONSEQUENCES TO HOLDERS OF THE CERTIFICATES
 
     Treatment of the Trust Fund as a Partnership.  In the case of a Trust Fund
that will elect to be treated as a partnership, the Trust Fund and the Master
Servicer will agree, and the holders of Certificates will agree by their
purchase of Certificates, to treat the Trust Fund as a partnership for purposes
of federal and state income tax, franchise tax and any other tax measured in
whole or in part by income, with the assets of the partnership being the assets
held by the Trust Fund, the partners of the partnership being the holders of
Certificates, and the Notes being debt of the partnership. However, the proper
characterization of the arrangement involving the Trust Fund, the Certificates,
the Notes, the Trust Fund and the Master Servicer is not clear because there is
no authority on transactions closely comparable to that contemplated herein.
 
     A variety of alternative characterizations are possible. For example,
because the Certificates have certain features characteristic of debt, the
Certificates might be considered debt of the Trust Fund. Any such
characterization would not result in materially adverse tax consequences to
holders of Certificates as compared to the consequences from treatment of the
Certificates as equity in a partnership, described below. The following
discussion assumes that the Certificates represent equity interests in a
partnership.
 
     Indexed Securities, etc.  The following discussion assumes that all
payments on the Certificates are denominated in U.S. dollars, none of the
Certificates are Indexed Securities or Stripped Securities, and that a Series of
Securities includes a single class of Certificates. If these conditions are not
satisfied with respect to any given Series of Certificates, additional tax
considerations with respect to such Certificates will be disclosed in the
applicable Prospectus Supplement.
 
     Partnership Taxation.  As a partnership, the Trust Fund will not be subject
to federal income tax. Rather, each holder of a Certificate will be required to
separately take into account such holder's allocated share of income, gains,
losses, deductions and credits of the Trust Fund. The Trust Fund's income will
consist primarily of interest and finance charges earned on the Loans (including
appropriate adjustments for market
 
                                       108
<PAGE>   110
 
discount, OID and bond premium) and any gain upon collection or disposition of
Loans. The Trust Fund's deductions will consist primarily of interest accruing
with respect to the Notes, servicing and other fees, and losses or deductions
upon collection or disposition of Loans.
 
     The tax items of a partnership are allocable to the partners in accordance
with the Code, Treasury regulations and the partnership agreement (here, the
Trust Agreement and related documents). The Trust Agreement will provide, in
general, that the Certificateholders will be allocated taxable income of the
Trust Fund for each month equal to the sum of (i) the interest that accrues on
the Certificates in accordance with their terms for such month, including
interest accruing at the Pass-Through Rate for such month and interest on
amounts previously due on the Certificates but not yet distributed; (ii) any
Trust Fund income attributable to discount on the Loans that corresponds to any
excess of the principal amount of the Certificates over their initial issue
price (iii) prepayment premium payable to the holders of Certificates for such
month; and (iv) any other amounts of income payable to the holders of
Certificates for such month. Such allocation will be reduced by any amortization
by the Trust Fund of premium on Loans that corresponds to any excess of the
issue price of Certificates over their principal amount. All remaining taxable
income of the Trust Fund will be allocated to the Depositor. Based on the
economic arrangement of the parties, this approach for allocating Trust Fund
income should be permissible under applicable Treasury regulations, although no
assurance can be given that the IRS would not require a greater amount of income
to be allocated to holders of Certificates. Moreover, even under the foregoing
method of allocation, holders of Certificates may be allocated income equal to
the entire Pass-Through Rate plus the other items described above even though
the Trust Fund might not have sufficient cash to make current cash distributions
of such amount. Thus, cash basis holders will in effect be required to report
income from the Certificates on the accrual basis and holders of Certificates
may become liable for taxes on Trust Fund income even if they have not received
cash from the Trust Fund to pay such taxes. In addition, because tax allocations
and tax reporting will be done on a uniform basis for all holders of
Certificates but holders of Certificates may be purchasing Certificates at
different times and at different prices, holders of Certificates may be required
to report on their tax returns taxable income that is greater or less than the
amount reported to them by the Trust Fund.
 
     All of the taxable income allocated to a holder of a Certificate that is a
pension, profit sharing or employee benefit plan or other tax-exempt entity
(including an individual retirement account) will constitute "unrelated business
taxable income" generally taxable to such a holder under the Code.
 
     An individual taxpayer's share of expenses of the Trust Fund (including
fees to the Master Servicer but not interest expense) would be miscellaneous
itemized deductions. Such deductions might be disallowed to the individual in
whole or in part and might result in such holder being taxed on an amount of
income that exceeds the amount of cash actually distributed to such holder over
the life of the Trust Fund.
 
     The Trust Fund intends to make all tax calculations relating to income and
allocations to holders of Certificates on an aggregate basis. If the IRS were to
require that such calculations be made separately for each Loan, the Trust Fund
might be required to incur additional expense but it is believed that there
would not be a material adverse effect on holders of Certificates.
 
     Discount and Premium.  It is believed that the Loans were not issued with
OID, and, therefore, the Trust Fund should not have OID income. However, the
purchase price paid by the Trust Fund for the Loans may be greater or less than
the remaining principal balance of the Loans at the time of purchase. If so, the
Loan will have been acquired at a premium or discount, as the case may be. (As
indicated above, the Trust Fund will make this calculation on an aggregate
basis, but might be required to recompute it on a Loan by Loan basis.)
 
     If the Trust Fund acquires the Loans at a market discount or premium, the
Trust Fund will elect to include any such discount in income currently as it
accrues over the life of the Loans or to offset any such premium against
interest income on the Loans. As indicated above, a portion of such market
discount income or premium deduction may be allocated to holders of
Certificates.
 
     Section 708 Termination.  Under Section 708 of the Code, the Trust Fund
will be deemed to terminate for federal income tax purposes if 50% or more of
the capital and profits interests in the Trust Fund are sold or
 
                                       109
<PAGE>   111
 
exchanged within a 12-month period. If such a termination occurs, the Trust Fund
will be considered to contribute all of its assets and liabilities to a new
partnership and, immediately thereafter, to liquidate by distributing interests
in the new partnership to the Certificateholders, with the Trust Fund, as the
new partnership, thereafter continuing the business of the partnership deemed
liquidated. The Trust Fund will not comply with certain technical requirements
that might apply when such a constructive termination occurs. As a result, the
Trust Fund may be subject to certain tax penalties and may incur additional
expenses if it is required to comply with those requirements. Furthermore, the
Trust Fund might not be able to comply due to lack of data.
 
     Disposition of Certificates.  Generally, capital gain or loss will be
recognized on a sale of Certificates in an amount equal to the difference
between the amount realized and the seller's tax basis in the Certificates sold.
A holder's tax basis in a Certificate will generally equal the holder's cost
increased by the holder's share of Trust Fund income (includible in income) and
decreased by any distributions received with respect to such Certificate. In
addition, both the tax basis in the Certificates and the amount realized on a
sale of a Certificate would include the holder's share of the Notes and other
liabilities of the Trust Fund. A holder acquiring Certificates at different
prices may be required to maintain a single aggregate adjusted tax basis in such
Certificates, and, upon sale or other disposition of some of the Certificates,
allocate a portion of such aggregate tax basis to the Certificates sold (rather
than maintaining a separate tax basis in each Certificate for purposes of
computing gain or loss on a sale of that Certificate).
 
     Any gain on the sale of a Certificate attributable to the holder's share of
unrecognized accrued market discount on the Loans would generally be treated as
ordinary income to the holder and would give rise to special tax reporting
requirements. The Trust Fund does not expect to have any other assets that would
give rise to such special reporting requirements. Thus, to avoid those special
reporting requirements, the Trust Fund will elect to include market discount in
income as it accrues.
 
     If a holder of a Certificate is required to recognize an aggregate amount
of income (not including income attributable to disallowed itemized deductions
described above) over the life of the Certificates that exceeds the aggregate
cash distributions with respect thereto, such excess will generally give rise to
a capital loss upon the retirement of the Certificates.
 
     Allocations Between Transferors and Transferees.  In general, the Trust
Fund's taxable income and losses will be determined monthly and the tax items
for a particular calendar month will be apportioned among the holders of
Certificates in proportion to the principal amount of Certificates owned by them
as of the close of the last day of such month. As a result, a holder purchasing
Certificates may be allocated tax items (which will affect its tax liability and
tax basis) attributable to periods before the actual transaction.
 
     The use of such a monthly convention may not be permitted by existing
regulations. If a monthly convention is not allowed (or only applies to
transfers of less than all of the partner's interest), taxable income or losses
of the Trust Fund might be reallocated among the holders of Certificates. The
Trust Fund's method of allocation between transferors and transferees may be
revised to conform to a method permitted by future regulations.
 
     Section 754 Election.  In the event that a holder of a Certificate sells
its Certificates at a profit (loss), the purchasing holder of a Certificate will
have a higher (lower) basis in the Certificates than the selling holder of a
Certificate had. The tax basis of the Trust Fund's assets will not be adjusted
to reflect that higher (or lower) basis unless the Trust Fund were to file an
election under Section 754 of the Code. In order to avoid the administrative
complexities that would be involved in keeping accurate accounting records, as
well as potentially onerous information reporting requirements, the Trust Fund
will not make such election. As a result, holders of Certificates might be
allocated a greater or lesser amount of Trust Fund income than would be
appropriate based on their own purchase price for Certificates.
 
     Administrative Matters.  The Owner Trustee (as defined in the applicable
Prospectus Supplement) is required to keep or have kept complete and accurate
books of the Trust Fund. Such books will be maintained for financial reporting
and tax purposes on an accrual basis and the fiscal year of the Trust Fund will
be the calendar year. The Owner Trustee will file a partnership information
return (IRS Form 1065) with the IRS
 
                                       110
<PAGE>   112
 
for each taxable year of the Trust Fund and will report each holder's allocable
share of items of Trust Fund income and expense to holders and the IRS on
Schedule K-1. The Trust Fund will provide the Schedule K-l information to
nominees that fail to provide the Trust Fund with the information statement
described below and such nominees will be required to forward such information
to the beneficial owners of the Certificates. Generally, holders must file tax
returns that are consistent with the information return filed by the Trust Fund
or be subject to penalties unless the holder notifies the IRS of all such
inconsistencies.
 
     Under Section 6031 of the Code, any person that holds Certificates as a
nominee at any time during a calendar year is required to furnish the Trust Fund
with a statement containing certain information on the nominee, the beneficial
owners and the Certificates so held. Such information includes (i) the name,
address and taxpayer identification number of the nominee and (ii) as to each
beneficial owner (x) the name, address and identification number of such person,
(y) whether such person is a United States person, a tax-exempt entity or a
foreign government, an international organization, or any wholly owned agency or
instrumentality of either of the foregoing, and (z) certain information on
Certificates that were held, bought or sold on behalf of such person throughout
the year. In addition, brokers and financial institutions that hold Certificates
through a nominee are required to furnish directly to the Trust Fund information
as to themselves and their ownership of Certificates. A clearing agency
registered under Section 17A of the Exchange Act is not required to furnish any
such information statement to the Trust Fund. The information referred to above
for any calendar year must be furnished to the Trust Fund on or before the
following January 31. Nominees, brokers and financial institutions that fail to
provide the Trust Fund with the information described above may be subject to
penalties.
 
     The Depositor will be designated as the tax matters partner in the related
Agreement and, as such, will be responsible for representing the holders of
Certificates in any dispute with the IRS. The Code provides for administrative
examination of a partnership as if the partnership were a separate and distinct
taxpayer. Generally, the statute of limitations for partnership items does not
expire before three years after the date on which the partnership information
return is filed. Any adverse determination following an audit of the return of
the Trust Fund by the appropriate taxing authorities could result in an
adjustment of the returns of the holders of Certificates, and, under certain
circumstances, a holder of a Certificate may be precluded from separately
litigating a proposed adjustment to the items of the Trust Fund. An adjustment
could also result in an audit of a holder's returns and adjustments of items not
related to the income and losses of the Trust Fund.
 
     Tax Consequences to Foreign Holders of Certificates.  It is not clear
whether the Trust Fund would be considered to be engaged in a trade or business
in the United States for purposes of federal withholding taxes with respect to
non-U.S. persons because there is no clear authority dealing with that issue
under facts substantially similar to those described herein. Although it is not
expected that the Trust Fund would be engaged in a trade or business in the
United States for such purposes, the Trust Fund will withhold as if it were so
engaged in order to protect the Trust Fund from possible adverse consequences of
a failure to withhold. The Trust Fund expects to withhold on the portion of its
taxable income that is allocable to foreign holders of Certificates pursuant to
Section 1446 of the Code, as if such income were effectively connected to a U.S.
trade or business, at a rate of 35% for foreign holders that are taxable as
corporations and 39.6% for all other foreign holders. Subsequent adoption of
Treasury regulations or the issuance of other administrative pronouncements may
require the Trust Fund to change its withholding procedures. In determining a
holder's withholding status, the Trust Fund may rely on IRS Form W-8, IRS Form
W-9 or the holder's certification of nonforeign status signed under penalties of
perjury.
 
     The term "U.S. Person" means a citizen or resident of the United States, a
corporation or partnership, including an entity treated as a corporation or
partnership for U.S. federal income tax purposes created in the United States or
organized under the laws of the United States or any state thereof or the
District of Columbia (except, in the case of a partnership as otherwise provided
by regulations), an estate, the income of which is includible in gross income
for U.S. federal income tax purposes regardless of its source or a trust whose
administration is subject to the primary supervision of a United States court
and has one or more United States persons who have authority to control all
substantial decisions of the trust.
 
                                       111
<PAGE>   113
 
     Each foreign holder might be required to file a U.S. individual or
corporate income tax return (including, in the case of a corporation, the branch
profits tax) on its share of the Trust Fund's income. Each foreign holder must
obtain a taxpayer identification number from the IRS and submit that number to
the Trust Fund on Form W-8 in order to assure appropriate crediting of the taxes
withheld. A foreign holder generally would be entitled to file with the IRS a
claim for refund with respect to taxes withheld by the Trust Fund taking the
position that no taxes were due because the Trust Fund was not engaged in a U.S.
trade or business. However, interest payments made (or accrued) to a holder of a
Certificate who is a foreign person generally will be considered guaranteed
payments to the extent such payments are determined without regard to the income
of the Trust Fund. If these interest payments are properly characterized as
guaranteed payments, then the interest will not be considered "portfolio
interest." As a result, holders of Certificates will be subject to United States
federal income tax and withholding tax at a rate of 30 percent, unless reduced
or eliminated pursuant to an applicable treaty. In such case, a foreign holder
would only be entitled to claim a refund for that portion of the taxes in excess
of the taxes that should be withheld with respect to the guaranteed payments.
 
     Backup Withholding.  Distributions made on the Certificates and proceeds
from the sale of the Certificates will be subject to a "backup" withholding tax
of 31% if, in general, the Certificateholder fails to comply with certain
identification procedures, unless the holder is an exempt recipient under
applicable provisions of the Code.
 
                            STATE TAX CONSIDERATIONS
 
     In addition to the federal income tax consequences described in "Federal
Income Tax Consequences," potential investors should consider the state and
local income tax consequences of the acquisition, ownership, and disposition of
the Securities. State and local income tax law may differ substantially from the
corresponding federal law, and this discussion does not purport to describe any
aspect of the income tax laws of any state or locality. Therefore, potential
investors should consult their own tax advisors with respect to the various
state and local tax consequences of an investment in the Securities.
 
                              ERISA CONSIDERATIONS
 
GENERAL
 
     The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
and the Code impose certain requirements on employee benefit plans and certain
other retirement plans and arrangements (including, but not limited to,
individual retirement accounts and annuities), as well as on collective
investment funds and certain separate and general accounts in which such plans
or arrangements are invested (all of which are hereinafter referred to as a
"Plan"). Generally, ERISA applies to investments made by Plans. Among other
things, ERISA requires 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 such Plans. ERISA also imposes
certain duties on persons who are fiduciaries of Plans. Under ERISA, any person
who exercises any authority or control respecting the management or disposition
of the assets of a Plan is considered to be a fiduciary of such Plan (subject to
certain exceptions not here relevant).
 
     Any Plan fiduciary or other person which proposes to cause a Plan to
acquire any of the Securities should determine whether such an 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. More generally, any Plan fiduciary which
proposes to cause a Plan to acquire any of the Securities or any other person
proposing to use the assets of a Plan to acquire any of the Securities should
consult with its counsel with respect to the potential consequences under ERISA
and the Code (including under the prohibited transactions rules described below)
of the acquisition and ownership of such Securities.
 
     Certain employee benefit plans, such as governmental plans and church plans
(if no election has been made under section 410(d) of the Code), are not subject
to the restrictions of ERISA, and assets of such plans may be invested in the
Securities without regard to the ERISA considerations described below, subject
 
                                       112
<PAGE>   114
 
to other applicable federal and state law. 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 set forth in section 503 of the Code.
 
PROHIBITED TRANSACTIONS
 
GENERAL
 
     Sections 406 and 407 of ERISA and section 4975 of the Code prohibit certain
transactions involving the assets of a Plan and "disqualified persons" (within
the meaning of the Code) and "parties in interest" (within the meaning of ERISA,
collectively "Parties in Interest") who have certain specified relationships to
the Plan, unless an exemption applies (see below). Therefore, a Plan fiduciary
or any other person using the assets of a Plan considering an investment in the
Securities should also consider whether such an investment might constitute or
give rise to a prohibited transaction under ERISA or the Code, or whether there
is an applicable exemption.
 
PLAN ASSET REGULATION
 
     The United States Department of Labor ("DOL") has issued final regulations
defining the "assets" of a Plan for purposes of ERISA and the prohibited
transaction provisions of the Code (29 C.F.R. sec. 2510.3-101, the "Plan Asset
Regulation"). The Plan Asset Regulation describes the circumstances under which
the assets of an entity in which a Plan invests will be considered to be "plan
assets" such that any person who exercises control over such assets would be
subject to ERISA's fiduciary standards. Under the Plan Asset Regulation,
generally when a Plan invests in another entity, the Plan's assets do not
include, solely by reason of such investment, any of the underlying assets of
the entity. However, the Plan Asset Regulation provides that, if a Plan acquires
an "equity interest" in an entity that is neither a "publicly-offered security"
(defined as a security which is widely held, freely transferable and registered
under the Securities Exchange Act of 1934, as amended) nor a security issued by
an investment company registered under the Investment Company Act of 1940, as
amended, the assets of the entity will be treated as assets of the Plan unless
certain exceptions apply. If the Securities were deemed to be equity interests
and no statutory, regulatory or administrative exemption applies, the Trust Fund
could be considered to hold plan assets by reason of a Plan's investment in the
Securities. Such plan assets would include an undivided interest in any assets
held by the Trust Fund. In such an event, the Trustee and other persons, in
providing services with respect to the Trust Fund's assets, may be Parties in
Interest with respect to such Plans, subject to the fiduciary responsibility
provisions of ERISA, including the prohibited transaction provisions with
respect to transactions involving the Trust Fund's assets.
 
     Under the Plan Asset Regulation, the term "equity interest" is defined as
any interest in an entity other than an instrument that is treated as
indebtedness under "applicable local law" and which has no "substantial equity
features." Although the Plan Assets Regulation is silent with respect to the
question of which law constitutes "applicable local law" for this purpose, the
DOL has stated that these determinations should be made under the state law
governing interpretation of the instrument in question. In the preamble to the
Plan Assets Regulation, the DOL declined to provide a precise definition of what
features are equity features or the circumstances under which such features
would be considered "substantial," noting that the question of whether a plan's
interest has substantial equity features is an inherently factual one, but that
in making a determination it would be appropriate to take into account whether
the equity features are such that a Plan's investment would be a practical
vehicle for the indirect provision of investment management services.
 
EXEMPTION 83-1
 
     In Prohibited Transaction Class Exemption 83-1 ("PTE 83-1"), which amended
Prohibited Transaction Class Exemption 81-7, the DOL exempted from ERISA's
prohibited transaction rules certain 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
 
                                       113
<PAGE>   115
 
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 (discussed below) of PTE 83-1
are satisfied, investments by a Plan in Securities that represent interests in a
Pool consisting of Loans ("Single Family Securities") will be exempt from the
prohibitions of ERISA Sections 406(a) and 407 (relating generally to
transactions with Parties in Interest who are not fiduciaries) if the Plan
purchases the Single Family Securities at no more than fair market value and
will be exempt from the prohibitions of ERISA Sections 406(b)(1) and (2)
(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% of all Single Family
Securities, and at least 50% of all Single Family Securities are purchased by
persons independent of the pool sponsor or pool trustee. PTE 83-1 does not
provide an exemption for transactions involving Subordinate Securities.
Accordingly, unless otherwise provided in the related Prospectus Supplement, no
transfer of a Subordinate Security or a Security which is not a Single Family
Security may be made to a Plan pursuant to this exemption.
 
     The discussion in this and the next succeeding paragraph applies only to
Single Family Securities. The Depositor believes that, for purposes of PTE 83-1,
the term "mortgage pool pass-through certificate" would include Securities
issued in a Series consisting of only a single class of Securities provided that
the Securities evidence the beneficial ownership of both a specified percentage
of future interest payments (greater than 0%) and a specified percentage of
future principal payments (greater than 0%) on the Loans. It is not clear
whether a class of Securities that evidences the beneficial ownership in a Trust
Fund divided into Loan groups, beneficial ownership of a specified percentage of
interest payments only or principal payments only, or a notional amount of
either principal or interest payments, or a class of Securities entitled to
receive payments of interest and principal on the Loans only after payments to
other classes or after the occurrence of certain specified events would be a
"mortgage pass-through certificate" for purposes of PTE 83-1.
 
     PTE 83-1 sets forth three general conditions which must be satisfied for
any transaction to be eligible for exemption: (i) the maintenance of a system of
insurance or other protection for the pooled mortgage loans and property
securing such loans, and for indemnifying Securityholders against reductions in
pass-through payments due to property damage or defaults in loan payments in an
amount not less than the greater of one percent of the aggregate principal
balance of all covered pooled mortgage loans or the principal balance of the
largest covered pooled mortgage loan; (ii) the existence of a pool trustee who
is not an affiliate of the pool sponsor; and (iii) a limitation on the amount of
the payment retained by the pool sponsor, together with other funds inuring to
its benefit, to not more than adequate consideration for selling the mortgage
loans plus reasonable compensation for services provided by the pool sponsor to
the Pool.
 
     The Depositor believes that the first general condition referred to above
will be satisfied with respect to the Securities in a Series if any Reserve
Account, subordination by shifting of interests, pool insurance or other form of
credit enhancement described under "Credit Enhancement" herein (such reserve
account, subordination, pool insurance or other form of credit enhancement being
the system of insurance or other protection referred to above) with respect to
such Securities is maintained in an amount not less than the greater of one
percent of the aggregate principal balance of the Loans or the principal balance
of the largest Loan. See "Description of the Securities" herein. In the absence
of a ruling that the system of insurance or other protection with respect to a
Series of Securities satisfies the first general condition referred to above,
there can be no assurance that these features will be so viewed by the DOL. The
Trustee will not be affiliated with the Depositor.
 
     Each Plan fiduciary or other person who is responsible for making the
investment decisions whether to purchase or commit to purchase and to hold
Single Family Securities must make its own determination as to whether the first
and third general conditions, and the specific conditions described briefly in
the preceding paragraph, of PTE 83-1 have been satisfied, or as to the
availability of any other prohibited transaction exemptions.
 
                                       114

THE UNDERWRITER'S EXEMPTION
 
     The DOL has granted to Morgan Stanley & Co. Incorporated an administrative
exemption (Prohibited Transaction Exemption 90-24, 55 Fed. Reg. 20,548 (1990)
(the "Exemption") from certain of the prohibited transaction rules of ERISA and
the related excise tax provisions of Section 4975 of the Code with respect to
the initial purchase, the holding and the subsequent resale by Plans of
certificates in pass-through trusts that consist of certain receivables, loans,
and other obligations that meet the conditions and requirements of the
Exemption.
 
     Among the conditions that must be satisfied for the Exemption to apply are
the following:
 
          (1) the acquisition of the Securities by a Plan is on terms (including
     the price for such Securities) 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 Securities acquired by
     the Plan are not subordinated to the rights and interests evidenced by
     other certificates of the Trust Fund;
 
          (3) the Securities acquired by the Plan have received a rating at the
     time of such acquisition that is one of the three highest generic rating
     categories from one of Standard & Poor's Ratings Group ("S&P"), Moody's
     Investors Service, Inc. ("Moody's"), Duff & Phelps Inc. ("Duff & Phelps")
     or Fitch Investors Service, L.P. ("Fitch");
 
          (4) the Trustee must not be an affiliate of any other member of the
     Restricted Group (as defined below);
 
          (5) the sum of all payments made to and retained by the underwriter in
     connection with the distribution of the Securities represents not more than
     reasonable compensation for underwriting such Securities; the sum of all
     payments made to and retained by the Depositor pursuant to the assignment
     of the Trust Fund Assets to the Trust Fund represents not more than the
     fair market value of such Trust Fund Assets; the sum of all payments made
     to and retained by the Master Servicer and any other servicer represents
     not more than reasonable compensation for such person's services under the
     related Agreement and reimbursements of such person's reasonable expenses
     in connection therewith; and
 
          (6) the Plan investing in the Securities 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, as amended.
 
     The Trust Fund must also meet the following requirements:
 
          (i) the corpus of the Trust Fund must consist solely of assets of the
     type that have been included in other investment pools;
 
          (ii) certificates evidencing interests in such other investment pools
     must have been rated in one of the three highest rating categories of S&P,
     Moody's, Fitch or Duff & Phelps for at least one year prior to the Plan's
     acquisition of the Securities; and
 
          (iii) certificates evidencing interests in such other investment pools
     must have been purchased by investors other than Plans for at least one
     year prior to any Plan's acquisition of the Securities.
 
     Moreover, the Exemption provides relief from certain self-dealing/conflict
of interest prohibited transactions that may occur when any person who has
discretionary authority or renders investment advice with respect to the
investment of plan assets causes a Plan to acquire certificates in a trust,
provided that, among other requirements: (i) such person (or its affiliate) is
an obligor with respect to five percent or less of the fair market value of the
obligations or receivables contained in the trust; (ii) the Plan is not a plan
with respect to which any member of the Restricted Group (as defined below) is
the "plan sponsor" (as defined in Section 3(16)(B) of ERISA); (iii) in the case
of an acquisition in connection with the initial issuance of certificates, at
least fifty percent of each class of certificates in which Plans have invested
is acquired by persons independent of the Restricted Group (as defined below)
and at least fifty percent of the aggregate interest in the trust fund is
acquired by persons independent of the Restricted Group; (iv) the Plan's
investment in
 
                                       115
<PAGE>   117
 
certificates of any class does not exceed twenty-five percent of all of the
certificates of that class outstanding at the time of the acquisition; and (v)
immediately after the acquisition, no more than twenty-five percent of the
assets of the Plan with respect to which such person has discretionary authority
or renders investment advice 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 the Seller, the
Depositor, Morgan Stanley and the other underwriters set forth in the related
Prospectus Supplement, the Trustee, the Master Servicer, the Pool Insurer, any
obligor with respect to the Trust Fund Asset included in the Trust Fund
constituting more than five percent of the aggregate unamortized principal
balance of the assets in the Trust Fund, or any affiliate of any of such parties
(the "Restricted Group").
 
     The Exemption may apply to the acquisition, holding and transfer of the
Securities by Plans if all of the conditions of the Exemption are met, including
those within the control of the investor. Notwithstanding any of the foregoing,
the Exemption will not apply with respect to any Securities until such time as
the balance of the related Pre-Funding Account, if any, is reduced to zero.
Accordingly, until such time, the Securities may not be purchased by Plans
pursuant to the Exemption. As of the date hereof, there is no single Trust Fund
Asset included in the Trust Fund that constitutes more than five percent of the
aggregate unamortized principal balance of the assets of the Trust Fund.
 
INSURANCE COMPANY PURCHASERS
 
     Purchasers that are insurance companies should consult with their legal
advisors with respect to the applicability of Prohibited Transaction Class
Exemption ("PTE") 95-60, regarding transactions by insurance company general
accounts. In addition to any exemption that may be available under PTE 95-60 for
the purchase and holding of Securities by an insurance company general account,
the Small Business Job Protection Act of 1996 added a new Section 401(c) to
ERISA, which provides certain 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 Code, for transactions
involving an insurance company general account. Pursuant to Section 401(c) of
ERISA, the DOL is required to issue final regulations ("401(c) Regulations") no
later than December 31, 1997 which are 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
401(c) Regulations become final, no person shall 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 (i) as otherwise provided by the Secretary of Labor in the 401(c)
Regulations to prevent avoidance of the regulations or (ii) an action is brought
by the Secretary of Labor for certain 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 401(c) Regulations may
be treated as plan assets. In addition, because Section 401(c) does not relate
to insurance company separate accounts, separate account assets are still
treated as plan assets of any Plan invested in such separate account. Insurance
companies contemplating the investment of general account assets in the
Securities should consult with their legal counsel with respect to the
applicability of 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 401(c) Regulations become final.
 
                                LEGAL INVESTMENT
 
     The Prospectus Supplement for each series of Securities will specify which,
if any, of the classes of Securities offered thereby constitute "mortgage
related securities" for purposes of the Secondary Mortgage Market Enhancement
Act of 1984 ("SMMEA"). Classes of Securities that qualify as "mortgage related
securities" 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
pursuant to or existing under the laws of the United States or of any state
(including the District of Columbia
 
                                       116
<PAGE>   118
 
and Puerto Rico) whose authorized investments are subject to state regulations
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, if a state enacts legislation prior to October 4, 1991 specifically
limiting the legal investment authority of any such entities with respect to
"mortgage related securities," securities will constitute legal investments for
entities subject to such legislation only to the extent provided therein.
Approximately twenty-one states adopted such legislation prior to the October 4,
1991 deadline. 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 securities, or require the sale or other disposition
of securities, so long as such contractual commitment was made or such
securities were acquired prior to the enactment of such 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 Securities
without limitations as to the percentage of their assets represented thereby,
federal credit unions may invest in mortgage related securities, and national
banks may purchase securities for their own account without regard to the
limitations generally applicable to investment securities set forth in 12 U.S.C.
24 (Seventh), subject in each case to such regulations as the applicable federal
authority may prescribe. In this connection, federal credit unions should review
the National Credit Union Administration ("NCUA") Letter to Credit Unions No.
96, as modified by Letter to Credit Unions No. 108, which includes guidelines to
assist federal credit unions in making investment decisions for mortgage related
securities and the NCUA's regulation "Investment and Deposit Activities" (12
C.F.R. Part 703), which sets forth certain restrictions on investment by federal
credit unions in mortgage related securities (in each case whether or not the
class of Securities under consideration for purchase constituted a "mortgage
related security").
 
     All depository institutions considering an investment in the Securities
(whether or not the class of Securities under consideration for purchase
constitutes a "mortgage related security") should review the Federal Financial
Institutions Examination Council's Supervisory Policy Statement on the
Securities Activities (to the extent adopted by their respective regulators)
(the "Policy Statement") setting forth, in relevant part, certain securities
trading and sales practices deemed unsuitable for an institution's investment
portfolio, and guidelines for (and restrictions on) investing in mortgage
derivative products, including "mortgage related securities," which are
"high-risk mortgage securities" as defined in the Policy Statement. According to
the Policy Statement, such "high-risk mortgage securities" include securities
such as Securities not entitled to distributions allocated to principal or
interest, or Subordinated Securities. Under the Policy Statement, it is the
responsibility of each depository institution to determine, prior to purchase
(and at stated intervals thereafter), whether a particular mortgage derivative
product is a "high-risk mortgage security," and whether the purchase (or
retention) of such a product would be consistent with the Policy Statement.
 
     The foregoing does not take into consideration the applicability of
statutes, rules, regulations, orders guidelines or agreements generally
governing investments made by a particular investor, including, but not limited
to "prudent investor" provisions which may restrict or prohibit investment in
securities which are not "interest bearing" or "income paying."
 
     There may be other restrictions on the ability of certain investors,
including depository institutions, either to purchase Securities or to purchase
Securities 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 Securities constitute legal investments for such
investors.
 
                             METHOD OF DISTRIBUTION
 
     The Securities offered hereby and by the related Prospectus Supplement will
be offered in Series. The distribution of the Securities may be effected from
time to time in one or more transactions, including negotiated transactions, at
a fixed public offering price or at varying prices to be determined at the time
of sale or at the time of commitment therefor. If so specified in the related
Prospectus Supplement, the Securities will be distributed in a firm commitment
underwriting, subject to the terms and conditions of the underwriting agreement,
by Morgan Stanley & Co. Incorporated ("Morgan Stanley") acting as underwriter
with other
 
                                       117
<PAGE>   119
 
underwriters, if any, named therein. In such event, the Prospectus Supplement
may also specify that the underwriters will not be obligated to pay for any
Securities agreed to be purchased by purchasers pursuant to purchase agreements
acceptable to the Depositor. In connection with the sale of Securities,
underwriters may receive compensation from the Depositor or from purchasers of
Securities in the form of discounts, concessions or commissions. The Prospectus
Supplement will describe any such compensation paid by the Depositor.
 
     Alternatively, the Prospectus Supplement may specify that Securities will
be distributed by Morgan Stanley acting as agent or in some cases as principal
with respect to Securities that it has previously purchased or agreed to
purchase. If Morgan Stanley acts as agent in the sale of Securities, Morgan
Stanley will receive a selling commission with respect to such Securities,
depending on market conditions, expressed as a percentage of the aggregate
principal balance or notional amount of such Securities as of the Cut-off Date.
The exact percentage for each Series of Securities will be disclosed in the
related Prospectus Supplement. To the extent that Morgan Stanley elects to
purchase Securities as principal, Morgan Stanley may realize losses or profits
based upon the difference between its purchase price and the sales price. The
Prospectus Supplement with respect to any Series offered other than through
underwriters will contain information regarding the nature of such offering and
any agreements to be entered into between the Depositor and purchasers of
Securities of such Series.
 
     The Depositor will indemnify Morgan Stanley and any underwriters against
certain civil liabilities, including liabilities under the Securities Act of
1933, or will contribute to payments Morgan Stanley and any underwriters may be
required to make in respect thereof.
 
     In the ordinary course of business, Morgan Stanley and the Depositor may
engage in various securities and financing transactions, including repurchase
agreements to provide interim financing of the Depositor's mortgage loans
pending the sale of such mortgage loans or interests therein, including the
Securities.
 
     Securities will be sold primarily to institutional investors. Purchasers of
Securities, including dealers, may, depending on the facts and circumstances of
such purchases, be deemed to be "underwriters" within the meaning of the
Securities Act of 1933 in connection with reoffers and sales by them of
Securities. Certificateholders should consult with their legal advisors in this
regard prior to any such reoffer or sale.
 
     As to each Series of Securities, only those classes rated in an investment
grade rating category by any Rating Agency will be offered hereby. Any
non-investment grade class may be initially retained by the Depositor, and may
be sold by the Depositor at any time in private transactions.
 
                                 LEGAL MATTERS
 
     The validity of the Securities of each Series, including certain federal
income tax consequences with respect thereto, will be passed upon for the
Depositor by Andrews & Kurth L.L.P. or other counsel identified in the
Prospectus Supplement.
 
                             FINANCIAL INFORMATION
 
     A new Trust Fund will be formed with respect to each Series of Securities
and no Trust Fund will engage in any business activities or have any assets or
obligations prior to the issuance of the related Series of Securities.
Accordingly, no financial statements with respect to any Trust Fund will be
included in this Prospectus or in the related Prospectus Supplement.
 
                                     RATING
 
     It is a condition to the issuance of the Securities of each Series offered
hereby and by the Prospectus Supplement that they shall have been rated in one
of the four highest rating categories by the nationally recognized statistical
rating agency or agencies (each, a "Rating Agency") specified in the related
Prospectus Supplement.
 
                                       118
<PAGE>   120
 
     Any such rating would be based on, among other things, the adequacy of the
value of the Trust Fund Assets and any credit enhancement with respect to such
class and will reflect such Rating Agency's assessment solely of the likelihood
that holders of a class of Securities of such class will receive payments to
which such Securityholders are entitled under the related Agreement. Such rating
will not constitute an assessment of the likelihood that principal prepayments
on the related Loans will be made, the degree to which the rate of such
prepayments might differ from that originally anticipated or the likelihood of
early optional termination of the Series of Securities. Such rating should not
be deemed a recommendation to purchase, hold or sell Securities, inasmuch as it
does not address market price or suitability for a particular investor. Each
security rating should be evaluated independently of any other security rating.
Such rating will not address the possibility that prepayment at higher or lower
rates than anticipated by an investor may cause such investor to experience a
lower than anticipated yield or that an investor purchasing a Security at a
significant premium might fail to recoup its initial investment under certain
prepayment scenarios.
 
     There is also no assurance that any such rating will remain in effect for
any given period of time or that it may not be lowered or withdrawn entirely by
the Rating Agency in the future if in its judgment circumstances in the future
so warrant. In addition to being lowered or withdrawn due to any erosion in the
adequacy of the value of the Trust Fund Assets or any credit enhancement with
respect to a Series, such rating might also be lowered or withdrawn among other
reasons, because of an adverse change in the financial or other condition of a
credit enhancement provider or a change in the rating of such credit enhancement
provider's long term debt.
 
     The amount, type and nature of credit enhancement, if any, established with
respect to a Series of Securities will be determined on the basis of criteria
established by each Rating Agency rating classes of such Series. Such criteria
are sometimes based upon an actuarial analysis of the behavior of mortgage loans
in a larger group. Such analysis is often the basis upon which each Rating
Agency determines the amount of credit enhancement required with respect to each
such class. There can be no assurance that the historical data supporting any
such actuarial analysis will accurately reflect future experience nor any
assurance that the data derived from a large pool of mortgage loans accurately
predicts the delinquency, foreclosure or loss experience of any particular pool
of Loans. No assurance can be given that values of any Properties have remained
or will remain at their levels on the respective dates of origination of the
related Loans. If the residential real estate markets should experience an
overall decline in property values such that the outstanding principal balances
of the Loans in a particular Trust Fund and any secondary financing on the
related Properties become equal to or greater than the value of the Properties,
the rates of delinquencies, foreclosures and losses could be higher than those
now generally experienced in the mortgage lending industry. In additional,
adverse economic conditions (which may or may not affect real property values)
may affect the timely payment by mortgagors of scheduled payments of principal
and interest on the Loans and, accordingly, the rates of delinquencies,
foreclosures and losses with respect to any Trust Fund. To the extent that such
losses are not covered by credit enhancement, such losses will be borne, at
least in part, by the holders of one or more classes of the Securities of the
related Series.

* All amounts except the SEC Registration Fee are estimates of expenses incurred

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the General Corporation Law of Delaware empowers a
corporation to indemnify any person who was or is a party or is threatened to be
made a party 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 the corporation), by reason of the fact that he or she is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise. Depending on the character of the proceeding, a corporation may
indemnify against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred in connection with
such action, suit or proceeding if the person indemnified acted in good faith
and in a manner he or she reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no cause to believe his or her conduct was unlawful. In the case
of an action by or in the right of the corporation, no indemnification may be
made in respect to any claim, issue or matter as to which such person shall have
been adjudged to be liable to the corporation unless and only to the extent that
the Court of Chancery or the court in which such action or suit was brought
shall determine that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the court shall deem proper. Section 145
further provides that to the extent a director or officer of a corporation has
been successful in the defense of any action, suit or proceeding referred to
above or in the defense of any claim, issue or matter therein, he or she shall
be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him or her in connection therewith.
 
     The Certificate of Incorporation and Bylaws of the Registrant provide, in
effect, that, to the extent and under the circumstances permitted by Section 145
of the General Corporation Law of Delaware, the Registrant shall indemnify any
person who was or is a party or is threatened to be made a party to any action,
suit or proceeding of the type described above by reason of the fact that he or
she is or was a director, officer, employee or agent of the Registrant.

ITEM 17.  UNDERTAKINGS.
 
     (a) 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, as amended (the "Act");
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of this Registration Statement (or the most recent
        post-effective amendment hereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this 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 and of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective Registration Statement;
 
                                      II-2
<PAGE>   129
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this Registration Statement
        or any material change to such information in this Registration
        Statement;
 
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in this Registration
Statement.
 
          (2) That, for the purpose of determining any liability under the Act,
     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 remain unsold at the
     termination of the offering.
 
     (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Act, each filing of a Trust Fund's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
of 1934 that is incorporated by reference in this 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.
 
     (c) Insofar as indemnification for liabilities arising under the Act 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.
 
     (d) The undersigned Registrant hereby undertakes to file an application for
the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act of 1939 in accordance
with the rules and regulations prescribed by the Commission under Section
305(b)(2) of the Trust Indenture Act of 1939.

        Re:         Morgan Stanley ABS Capital I Inc.
                    Registration Statement on Form S-3

Ladies and Gentlemen:

        We have acted as counsel to Morgan Stanley ABS Capital I Inc., a
Delaware corporation ("the Depositor"), in connection with the authorization and
proposed issuance from time to time after the date hereof in one or more series
(each, a "Series") of up to $1,000,000 aggregate principal amount of
asset-backed certificates (the "Certificates") to be offered pursuant to a
registration statement on Form S-3 (such registration statement, the
"Registration Statement") relating to the Certificates. The Registration
Statement has been filed with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "1933 Act"), and
the rules and regulations promulgated thereunder. As set forth in the
Registration Statement, each Series of Certificates will be issued under and
pursuant to the conditions of a separate pooling and servicing agreement (each,
a "Pooling and Servicing Agreement") or a trust agreement (each, a "Trust
Agreement") among the Depositor, a master servicer to be identified in the
prospectus supplement for such Series of Certificates (the "Master Servicer" for
such Series) and a trustee to be identified in the prospectus supplement for
such Series of Certificates (the "Trustee" for such Series).

        We have examined originals or copies, certified or otherwise identified
to our satisfaction, of the organizational documents of the Depositor, the forms
of Pooling and Servicing Agreements incorporated by reference as exhibits to the
Registration Statement, the form of Trust Agreement incorporated by reference as
an exhibit to the Registration Statement, the forms of Certificates included in
such forms of Pooling and Servicing Agreements and Trust Agreement, the
prospectus (the "Prospectus") and forms of prospectus supplements incorporated
by reference as exhibits to the Registration Statement, and such other records,
documents and statutes as we have deemed necessary for the purpose of rendering
this opinion.

        Based upon the foregoing, we are of the opinion that:

        1.     When a Pooling and Servicing Agreement or a Trust Agreement, as
applicable, for a Series of Certificates has been duly and validly authorized by
all necessary action on the part of the Depositor and has been duly executed and
delivered by the Depositor, the Master Servicer, the Trustee and any other party
thereto for such Series, such Pooling and Servicing Agreement or Trust
Agreement,



<PAGE>   2

Morgan Stanley ABS Capital I Inc.

Page 2

as applicable, will constitute a legal, valid and binding agreement of the
Depositor, enforceable against the Depositor, in accordance with its terms,
except as enforcement thereof may be limited by (a) bankruptcy, insolvency
reorganization, liquidation, receivership, moratorium or other similar laws
relating to or affecting creditors' rights generally or (b) general principles
of equity or public policy, regardless of whether such enforceability is
considered in a proceeding in equity or at law.

        2.     When a Series of Certificates has been duly authorized by all
necessary action on the part of the Depositor, duly executed and authenticated
by the Trustee for such Series in accordance with the terms of the related
Pooling and Servicing Agreement or Trust Agreement, as applicable, and issued
and delivered against payment therefor as contemplated in the Registration
Statement, the Certificates of such Series will be legally and validly issued,
fully paid and nonassessable, and the holders thereof will be entitled to the
benefits of the related Pooling and Servicing Agreement or Trust Agreement, as
applicable.

        In rendering the foregoing opinions, we express no opinion as to the
laws of any jurisdiction other than the General Corporate Law of the State of
Delaware, the laws of the State of New York (excluding choice of law principles
therein) and the federal laws of the United States of America.

        We hereby consent to the filing of this letter as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the heading
"Legal Matters" in the Prospectus, without implying or admitting that we are
"experts" within the meaning of the 1933 Act or the rules and regulations of the
Commission issued thereunder, with respect to any part of the Registration
Statement, including this Exhibit 5.1.

                                   Sincerely,

        Re:         Morgan Stanley ABS Capital I Inc.,
                    Registration Statement on Form S-3

Ladies and Gentlemen:

        We have acted as counsel to Morgan Stanley ABS Capital I Inc., a
Delaware corporation (the "Depositor"), in connection with the authorization and
proposed issuance from time to time after the date hereof in one or more series
(each, a "Series") of up to $1,000,000 aggregate principal amount of
asset-backed notes (the "Notes") to be offered pursuant to a registration
statement on Form S-3 (such registration statement, the "Registration
Statement") relating to the Notes. The Registration Statement has been filed
with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "1933 Act"), and the rules and
regulations promulgated thereunder. As set forth in the Registration Statement,
each Series of Notes will be issued under and pursuant to the conditions of an
indenture (an "Indenture") between a trust fund to be identified in the
prospectus supplement for such Series of Notes (the "Trust Fund" for such
Series) and a trustee to be identified in the prospectus supplement for such
Series of Notes (the "Trustee" for such Series).

        We have examined originals or copies, certified or otherwise identified
to our satisfaction, of the organizational documents of the Depositor, the form
of Indenture incorporated by reference as an exhibit to the Registration
Statement, the form of Notes included in such form of Indenture, the prospectus
(the "Prospectus") and the forms of prospectus supplements incorporated by
reference as exhibits to the Registration Statement, and such other records,
documents and statutes as we have deemed necessary for the purpose of rendering
this opinion.

        Based upon the foregoing, we are of the opinion that:

        1.     When an Indenture for a Series of Notes has been duly and validly
authorized by all necessary action on the part of the Depositor, as sponsor of
the related Trust Fund, and has been duly executed and delivered by such Trust
Fund and the Trustee and any other party thereto for such Series, such Indenture
will constitute a legal, valid and binding agreement of such Trust Fund,
enforceable against the related Trust Fund, in accordance with its terms, except
as enforcement thereof may be limited by (a) bankruptcy, insolvency
reorganization, liquidation, receivership, moratorium or other similar laws
relating to or affecting creditors' rights generally or (b) general principles
of equity or public policy, regardless of whether such enforceability is
considered in a proceeding in equity or at law.

        2.     When a Series of Notes has been duly authorized by all necessary
action on the part of the Depositor, as sponsor of the related Trust Fund, duly
executed and authenticated by the Trustee for such Series in accordance with the
terms of the related Indenture, and issued and delivered against payment
therefor as contemplated in the Registration Statement, the Notes of such Series
will be valid and binding non-recourse obligations of such Trust Fund,
enforceable against such Trust Fund, in accordance with their terms, except as
enforcement thereof may be limited by (a) bankruptcy, insolvency reorganization,
liquidation, receivership, moratorium or other similar laws relating to or
affecting creditors' rights generally or (b) general principles of equity or
public policy, regardless of whether such enforceability is considered in a

        Re:         Morgan Stanley ABS Capital I Inc.
                    Registration Statement on Form S-3

Ladies and Gentlemen:

        We have acted as counsel to Morgan Stanley ABS Capital I Inc., a
Delaware corporation (the "Depositor"), in connection with the authorization and
proposed issuance from time to time after the date hereof in one or more series
(each, a "Series") of up to $1,000,000 aggregate principal amount of
asset-backed certificates (the "Certificates") and asset-backed notes (the
"Notes" and, together with the Certificates, the "Securities") to be offered
pursuant to a registration statement on Form S-3 (such registration statement,
the "Registration Statement") relating to the Securities. The Registration
Statement has been filed with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "1933 Act"), and
the rules and regulations promulgated thereunder. As set forth in the
Registration Statement, each Series of Certificates will be issued under and
pursuant to the conditions of a pooling and servicing agreement (each, a
"Pooling and Servicing Agreement") or a trust agreement (each, a "Trust
Agreement") among the Depositor, a master servicer to be identified in the
prospectus supplement for such Series of Certificates (the "Master Servicer" for
such Series) and a trustee to be identified in the prospectus supplement for
such Series of Certificates (the "Trustee" for such Series); each Series of
Notes will be issued under and pursuant to the conditions of an indenture (each,
an "Indenture") between a trust fund to be identified in the prospectus
supplement for such Series of Notes (the "Trust Fund" for such Series) and a
trustee to be identified in the prospectus supplement for such Series of Notes
(the "Trustee" for such Series).

        We have examined the prospectus contained in the Registration Statement
(the "Prospectus") and such other documents, records and instruments as we have
deemed necessary for the purpose of this opinion.

        In arriving at the opinion expressed below, we have assumed that each
Pooling and Servicing Agreement, each Trust Agreement and each Indenture will be
duly authorized by all necessary corporate action on the part of the Depositor,
the related Trustee, the Master Servicer, as applicable, and any other party
thereto for the related Series of Certificates or Notes and will be duly
executed and delivered by the Depositor or the related Trust Fund, as
applicable, the related Trustee, the Master Servicer, as applicable, and any
other party thereto substantially in the forms filed as exhibits to the
Registration Statement, that


<PAGE>   2

Morgan Stanley ABS Capital I Inc.

Page 2

the Certificates or the Notes of each Series will be duly executed and delivered
substantially in the forms contemplated by the Pooling and Servicing Agreement,
the Trust Agreement or the Indenture, as applicable, and that the Certificates
or the Notes will be sold in the manner described in the Registration Statement.

        Based upon such examination and the qualifications set forth herein and
in reliance thereon, we are of the opinion that the description of federal
income tax consequences appearing under the captions "Summary - Federal Income
Tax Consequences" and "Federal Income Tax Consequences" in the Prospectus
accurately describes the material federal income tax consequences to holders of
the Securities.

        The opinion herein is based upon our interpretations of current law,
including court authority and existing final and temporary treasury regulations,
which are subject to change both prospectively and retroactively, and upon the
facts and assumptions discussed herein. This opinion letter is limited to the
matters set forth herein, and no opinions are intended to be implied or may be
inferred beyond those expressly stated herein. Our opinion is rendered as of the
date hereof and we assume no obligation to update or supplement this opinion or
any matter related to this opinion to reflect any change of fact, circumstances
or law after the date hereof. In addition, our opinion is based on the
assumption that the matter, if litigated, will be properly presented to the
applicable court. Furthermore, our opinion is not binding on the Internal
Revenue Service or a court. Our opinion represents merely our best legal
judgment on the matters presented; others may disagree with our conclusion.
There can be no assurance that the Internal Revenue Service will not take a
contrary position or that a court would agree with our opinion if litigated. In
the event any one of the statements, representations or assumptions we have
relied upon to issue this opinion is incorrect, our opinion might be adversely
affected and may not be relied upon.

        We hereby consent to the filing of this letter as Exhibit 8.1 to the
Registration Statement and to the reference to this firm under the caption
"Federal Income Tax Consequences" in the Prospectus, without implying or
admitting that we are "experts" within the meaning of the 1933 Act or the rules
and regulations of the Commission issued thereunder, with respect to any part of
the Registration Statement, including this Exhibit 8.1.

                                           Sincerely,

                                           /s/ ANDREWS & KURTH L.L.P.
