The depositor will establish a trust with respect to the Series 1999-S18
Certificates under a pooling and servicing agreement. On the closing date, the

interest in the trust.

THE MORTGAGE POOL

The mortgage loans to be deposited into the trust have the following
characteristics as of the cut-off date:

                                    WEIGHTED
                       RANGE        AVERAGE

maturity (months)     237 to 360         358

*Indicates average principal balance.

For additional information regarding the mortgage pool see "Description of the
Mortgage Pool" in this prospectus supplement.

DISTRIBUTIONS ON THE OFFERED CERTIFICATES

Amount available for monthly distribution. On each monthly distribution date,
the trustee will make distributions to investors. The amount available for
distribution will include:

o collections of monthly payments on the mortgage loans, including prepayments
  and other unscheduled collections plus

o advances for delinquent payments minus

o the fees and expenses of the subservicers and the master servicer, including
  reimbursement for advances.

See "Description of the Certificates--Glossary of Terms--Available Distribution
Amount" in this prospectus supplement.

Priority of distributions. Distributions on the offered certificates will be
made from available amounts as follows:

o Distribution of interest to the interest-bearing Senior Certificates

o Distribution of principal to the Class A-P Certificates

o Distribution of principal to the remaining Senior Certificates entitled to
  principal

o Payment to master servicer for certain unreimbursed advances

o Distribution to the Class M Certificates in the following order:

      o Interest to the Class M-1 Certificates

      o Principal to the Class M-1 Certificates

      o Interest to the Class M-2 Certificates

      o Principal to the Class M-2 Certificates

      o Interest to the Class M-3 Certificates

      o Principal to the Class M-3 Certificates

Interest distributions. The amount of interest owed to each class of interest-
bearing certificates on each distribution date will equal:

o the pass-through rate for that class of certificates multiplied by

                                      S-6
<PAGE>

o the principal balance or notional amount of that class of certificates as of
  the day immediately prior to the related distribution date multiplied by

o 1/12th minus

o the share of some types of interest shortfalls allocated to that class.

See "Description of the Certificates--Interest Distributions" in this prospectus
supplement.

Allocations of principal. Principal distributions on the certificates will be
allocated among the various classes of offered certificates as described in this
prospectus supplement. Until the distribution date in September 2004, all
principal prepayments on the mortgage loans will be distributed among the senior
certificates, other than the Class A-9 Certificates, unless the interest-bearing
senior certificates entitled to principal distributions are no longer
outstanding. Not all outstanding senior certificates will receive principal on
each distribution date. The Class A-P Certificates receive only a portion of the
principal received from each mortgage loan that has a net mortgage rate of less
than 7.00%. The Class A-V Certificates are not entitled to receive any principal
distributions.

See "Description of the Certificates--Principal Distributions on the Senior
Certificates" and "--Principal Distributions on the Class M Certificates" in
this prospectus supplement.

CREDIT ENHANCEMENT

ALLOCATION OF LOSSES.   Most losses on the mortgage loans will be allocated in
full to the first class listed below with a principal balance greater than zero:

o Class B-3

o Class B-2

o Class B-1

o Class M-3

o Class M-2

o Class M-1

When this occurs, the principal balance of the class to which the loss is
allocated is reduced, without a corresponding payment of principal.

If none of the Class M Certificates or Class B Certificates are outstanding,
losses on the mortgage loans will be allocated proportionately among the senior
certificates, in accordance with the special rules mentioned below.

Not all losses will be allocated in the priority described in the third
preceding paragraph. Losses due to natural disasters such as floods and
earthquakes, fraud by a mortgagor, or bankruptcy of a mortgagor will be
allocated as described in the third preceding paragraph only up to specified
amounts. Losses of these types in excess of the specified amount and losses due
to other extraordinary events will be allocated proportionately among all
outstanding classes of certificates except as stated in the following paragraph.
Therefore, the Class M Certificates and Class B Certificates do not act as
credit enhancement for the senior certificates for such losses.

Special loss allocation for Class A-P Certificates. Whenever losses are
allocated to the senior certificates, the Class A-P Certificates will share in
the loss only if the mortgage loan had a net mortgage rate less than 7.00%. In
that case, the Class A-P Certificates will bear a share of the loss equal to
their percentage interest in the principal of that mortgage loan.

See "Description of the Certificates--Allocation of Losses; Subordination" in
this prospectus supplement.

PRIORITY OF DISTRIBUTIONS.   All or a disproportionately large portion of
principal prepayments and other unscheduled payments of principal will be
allocated to the senior certificates during the first nine years after the
closing date. This provides additional credit enhancement for the senior
certificates by reserving a greater portion of the principal balances of the
Class M Certificates and Class B Certificates for absorption of losses.

ADVANCES

For any month, if the master servicer does not receive the full scheduled
payment on a mortgage loan, the master servicer will advance funds to cover the
amount of the scheduled payment that was not made. However, the master servicer
will advance funds only if it determines that the advance will be recoverable
from future payments or collections on that mortgage loan.

See "Description of the Certificates--Advances" in this prospectus supplement.

OPTIONAL TERMINATION

On any distribution date on which the aggregate principal balance of the
mortgage loans is less than 10% of their aggregate principal balance as of the
cut-off date, the master servicer or the depositor will have the option to:

o purchase from the trust all remaining mortgage loans, causing an early
  retirement of the certificates;
  or

o purchase all the certificates.

Under either type of optional purchase, holders of the outstanding certificates
will receive the outstanding principal balance of the certificates in full with
accrued interest. However, any optional purchase of the remaining mortgage loans
may result in a shortfall to the holders of the most subordinate classes of
certificates outstanding, if the trust then holds properties acquired from
foreclosing upon defaulted loans. In either case, there will be no reimbursement
of principal reductions or related interest that resulted from losses allocated
to the certificates.

See "Pooling and Servicing Agreement--Termination" in this prospectus supplement
and "The Pooling and Servicing Agreement--Termination; Retirement of
Certificates" in the prospectus.

RATINGS

When issued, the offered certificates will receive ratings which are not lower
than those listed in the table on pages S-4 and S-5 of this prospectus
supplement. The ratings on the offered certificates address the likelihood that
holders of the offered certificates will receive all distributions on the
underlying mortgage loans to which they are entitled. A security rating is not a
recommendation to buy, sell or hold a security and may be changed or withdrawn
at any time by the assigning rating agency. The ratings also do not address the
rate of principal prepayments on the mortgage loans. For example, the rate of
prepayments, if different than originally anticipated, could adversely affect
the yield realized by holders of the offered certificates or cause holders of
the Class A-V Certificates to fail to fully recover their initial investments.

See "Ratings" in this prospectus supplement.

LEGAL INVESTMENT

When issued, the Class A, Class R and Class M-1 Certificates will, and the Class
M-2 and Class M-3 Certificates will not, be "mortgage related securities" for
purposes of SMMEA. You should consult your legal advisors in determining whether
and to what extent the offered certificates constitute legal investments for
you.

See "Legal Investment" in this prospectus supplement for important information
concerning possible restrictions on ownership of the offered certificates by
regulated institutions.

ERISA CONSIDERATIONS

The Class A Certificates may be considered eligible for purchase by persons
investing assets of employee benefit plans or individual retirement accounts.
Sales of the Class M Certificates and the Class R Certificates to such plans or
retirement accounts are prohibited, except as permitted under "ERISA
Considerations" in this prospectus supplement. If you invest in a Class M
Certificate, you will be deemed to represent that you comply with these
restrictions.

See "ERISA Considerations" in this prospectus supplement and in the prospectus.

TAX STATUS

For federal income tax purposes, the depositor will elect to treat the trust as
a real estate mortgage investment conduit. The certificates, other than the
Class R Certificates, will represent ownership of regular interests in the trust
and will be treated as representing ownership of debt for federal income tax
purposes. You will be required to include in income all interest and original
issue discount, if any, on such certificates in accordance with the accrual
method of accounting regardless of your usual methods of accounting. For federal
income tax purposes, the Class R Certificates will be the sole residual interest
in the real estate mortgage investment conduit.

For further information regarding the federal income tax consequences of
investing in the offered certificates, including important information regarding
the tax treatment of the Class R Certificates, see "Material Federal Income Tax
Consequences" in this prospectus supplement and in the prospectus.

                                  RISK FACTORS

     The offered certificates are not suitable investments for all investors. In
particular, you should not purchase any class of offered certificates unless you
understand the prepayment, credit, liquidity and market risks associated with
that class.

     The offered certificates are complex securities. You should possess, either
alone or together with an investment advisor, the expertise necessary to
evaluate the information contained in this prospectus supplement and the
prospectus in the context of your financial situation and tolerance for risk.

     You should carefully consider, among other things, the following factors in
connection with the purchase of the offered certificates:

                                   realize a desired yield. Illiquidity can have a severe adverse effect on the
                                   market value of your certificates.

                                   Any class of offered certificates may experience illiquidity, although
                                   generally illiquidity is more likely for classes that are especially sensitive

of prepayments.
   o the rate and timing of principal payments on the mortgage loans, including
                                     prepayments, defaults and liquidations, and repurchases due to breaches of
                                     representations or warranties;

                                   o the pass-through rate for that class;

                                   o interest shortfalls due to mortgagor prepayments; and

                                   o the purchase price of that class.

                                   The rate of prepayments is one of the most important and least predictable of
                                   these factors.

                                   In general, if you purchase a certificate at a price higher than its
                                   outstanding principal balance and principal distributions on your certificate
                                   occur faster than you assumed at the time of purchase, your yield will be
                                   lower than you anticipated. Conversely, if you purchase a certificate at a
                                   price lower than its outstanding principal balance and principal distributions
                                   on that class occur more slowly than you assumed at the time of purchase, your
                                   yield will be lower than you anticipated.

mortgage loans will vary           rate and timing of principal distributions on the offered certificates are
depending on future market         highly uncertain. Generally, when market interest rates increase, borrowers
conditions, and other factors.     are less likely to prepay their mortgage loans. This could result in a slower
                                   return of principal to you at a time when you might have been able to reinvest
                                   your funds at a higher rate of interest than the pass-through rate on your
                                   class of certificates. On the other hand, when market interest rates decrease,
                                   borrowers are generally more likely to prepay their mortgage loans. This could
                                   result in a faster return of principal to you at a time when you might not be
                                   able to reinvest your funds at an interest rate as high as the pass-through
                                   rate on your class of certificates.

                                   Refinancing programs, which may involve soliciting all or some of the
                                   mortgagors to refinance their mortgage loans, may increase the rate of
                                   prepayments on the mortgage loans. These refinancing programs may be offered
                                   by the master servicer, any subservicer or their affiliates, and may include
                                   streamlined documentation programs as well as programs under which a mortgage
                                   loan is modified to reduce the interest rate.

The yield on your certificates     The offered certificates of each class have different yield considerations and
will be affected by the specific   different sensitivities to the rate and timing of principal distributions. The
forms that apply to that class,    following is a general discussion of yield considerations and prepayment
discussed below.                   sensitivities of each class.

    Class A Certificates           The Class A Certificates are subject to various priorities for payment of
                                   principal. Distributions of principal on the Class A Certificates with an
                                   earlier priority of payment will be affected by the rates of prepayment of the
                                   mortgage loans early in the life of the mortgage pool. Those classes of
                                   Class A Certificates with a later priority of payment will be affected by the
                                   rates of prepayment of the mortgage loans experienced both before and after
                                   the commencement of principal distributions on those classes, and will be more
                                   likely to be affected by losses on the mortgage loans not covered by the
                                   credit enhancement.

                                   See "Description of the Certificates--Principal Distributions on the Senior
                                   Certificates" in this prospectus supplement.

    Class A-7 Certificates         The interest rate on the Class A-7 Certificates will vary with LIBOR. THE
       and Class A-8               INTEREST RATE ON THE CLASS A-8 CERTIFICATES WILL VARY INVERSELY WITH A
       Certificates                MULTIPLE OF LIBOR. Therefore, the yield to investors on the Class A-7
                                   Certificates will be sensitive, and the Class A-8 Certificates will be
                                   extremely sensitive, to fluctuations of LIBOR.

    Class A-9 Certificates         It is not expected that the Class A-9 Certificates will receive any
                                   distributions of principal until the distribution date in

                                   September 2004. Until the distribution date in September 2008, the Class A-9
                                   Certificates may receive a portion of principal prepayments that is smaller
                                   than its pro rata share of principal prepayments.

    Class A-P Certificates         The Class A-P Certificates will receive a portion of the principal payments
                                   only on the mortgage loans that have net mortgage rates lower than 7.00%.
                                   Therefore, the yield on the Class A-P Certificates is extremely sensitive to
                                   the rate and timing of principal prepayments and defaults on the mortgage
                                   loans that have net mortgage rates lower than 7.00%.

                                   Mortgage loans with lower mortgage rates are less likely to be prepaid than
                                   mortgage loans with higher mortgage rates. If prepayments of principal on the
                                   mortgage loans that have net mortgage rates lower than 7.00% occur at a rate
                                   slower than an investor assumed at the time of purchase, the investor's yield
                                   will be adversely affected.

    Class A-V Certificates         The Class A-V Certificates will receive a portion of the interest payments
                                   only from mortgage loans that have net mortgage rates higher than 7.00%.
                                   Therefore, the yield on the Class A-V Certificates will be extremely sensitive
                                   to the rate and timing of principal prepayments and defaults on the mortgage
                                   loans that have net mortgage rates higher than 7.00%.

                                   Mortgage loans with higher mortgage rates are more likely to be prepaid than
                                   mortgage loans with lower mortgage rates. If the mortgage loans that have net
                                   mortgage rates higher than 7.00% are prepaid at a rate faster than an investor
                                   assumed at the time of purchase, the yield to investors in the Class A-V
                                   Certificates will be adversely affected. Investors in the Class A-V
                                   Certificates should fully consider the risk that a rapid rate of prepayments
                                   on the mortgage loans that have net mortgage rates higher than 7.00% could
                                   result in the failure of such investors to fully recover their investments.

    Class M Certificates           The yield to investors in each class of the Class M Certificates will be
                                   sensitive to the rate and timing of losses on the mortgage loans, if those
                                   losses are not covered by a more subordinate class of Class M Certificates or
                                   the Class B Certificates.

                                   It is not expected that the Class M Certificates will receive any
                                   distributions of principal prepayments until the distribution date in
                                   September 2004. After that date, all or a disproportionately large portion of
                                   principal prepayments on the mortgage loans may be allocated to the senior
                                   certificates, and none or a disproportionately small portion of principal
                                   prepayments may be paid to the holders of the Class M Certificates and
                                   Class B Certificates. As a result, the weighted average lives of the Class M
                                   Certificates may be longer than would otherwise be the case.

     The Depositor will establish a trust with respect to Series 1999-S18 on the
closing date, under a pooling and servicing agreement among the depositor, the
master servicer and the trustee, dated as of the cut-off date. On the closing
date, the depositor will deposit into the trust a pool of mortgage loans, that
in the aggregate will constitute a mortgage pool, secured by one- to four-family
residential properties with terms to maturity of not more than thirty years.

     Some capitalized terms used in this prospectus supplement have the meanings
given below under "Description of the Certificates--Glossary of Terms" or in the
prospectus under "Glossary."

                        DESCRIPTION OF THE MORTGAGE POOL

GENERAL

     The mortgage pool will consist of 1,176 mortgage loans with an aggregate
principal balance outstanding as of the cut-off date, after deducting payments
of principal due on the cut-off date, of $369,289,427. The mortgage loans are
secured by first liens on fee simple interests in one- to four-family
residential real properties. In each case, the property securing the mortgage
loan is referred to as the mortgaged property. The mortgage pool will consist of
conventional, fixed-rate, fully-amortizing, level monthly payment first mortgage
loans with terms to maturity of not more than 30 years from the date of
origination or modification. With respect to mortgage loans which have been
modified, references in this prospectus supplement to the date of origination
shall be deemed to be the date of the most recent modification. All percentages
of the mortgage loans described in this prospectus supplement are approximate
percentages by aggregate principal balance as of the cut-off date unless
otherwise indicated.

     All of the mortgage loans were purchased by the depositor through its
affiliate, Residential Funding, from unaffiliated sellers as described in this
prospectus supplement and in the prospectus, except in the case of 7.4% of the
mortgage loans, which were purchased by the depositor through its affiliate,
Residential Funding, from HomeComings Financial Network, Inc., a wholly-owned
subsidiary of the master servicer. 0.23% of the mortgage loans were purchased
from and are being or will be subserviced by GMAC Mortgage Corporation, an
affiliate of the master servicer. 11.6% of the mortgage loans were purchased
from and are being subserviced by Downey Savings & Loan, an unaffiliated seller.
Except as described in the preceding sentence, no unaffiliated seller sold more
than 9.6% of the mortgage loans to Residential Funding. 63.0% of the mortgage
loans are being or will be subserviced by HomeComings Financial Network, Inc.

     Under the terms of the pooling and servicing agreement, the depositor will
assign the representations and warranties made by the related sellers of the
mortgage loans to the trustee for the benefit of the certificateholders and will
also make limited representations and warranties regarding the mortgage loans as
of the date of issuance of the certificates. To the best of the depositor's
knowledge, none of the mortgage loans were sold to Residential Funding by
unaffiliated sellers that are institutions which are currently in receivership
or conservatorship or involved in other insolvency or bankruptcy proceedings, or
are no longer in existence.

     To the extent that any seller of the mortgage loans does not repurchase a
mortgage loan in the event of a breach of its representations and warranties
with respect to that mortgage loan, neither the depositor nor Residential
Funding will be required to repurchase the mortgage loan unless:

     o the breach also constitutes a breach of one of the depositor's or
       Residential Funding's representations and warranties with respect to that
       mortgage loan and

     o the breach materially and adversely affects the interests of the
       certificateholders in any such mortgage loan.

     In addition, neither the depositor nor Residential Funding will be required
to repurchase any mortgage loan in the event of a breach of its representations
and warranties with respect to that mortgage loan if the substance of any such
breach also constitutes fraud in the origination of the affected mortgage loan.
A limited amount of losses on mortgage loans as to which there was fraud in the
origination of those mortgage loans will be covered

MORTGAGE POOL CHARACTERISTICS

     None of the mortgage loans will have been originated prior to April 24,
1998 or will have a maturity date later than August 1, 2029. No mortgage loan
will have a remaining term to maturity as of the cut-off date of less than 237
months. The weighted average remaining term to maturity of the mortgage loans as
of the cut-off date will be approximately 358 months. The weighted average
original term to maturity of the mortgage loans as of the cut-off date will be
approximately 359 months. As used in this prospectus supplement the remaining
term to maturity means, as of any date of determination and with respect to any
mortgage loan, the number of months equaling the number of scheduled monthly
payments necessary to reduce the then-current Stated Principal Balance of that
mortgage loan to zero, assuming the related mortgagor will make all scheduled
monthly payments but no prepayments, on the mortgage loan thereafter.

     As of the cut-off date, none of the mortgage loans will be one month or
more delinquent in payment of principal and interest. For a description of the
methodology used to categorize mortgage loans as delinquent, see "Pooling and
Servicing Agreement--The Master Servicer" in this prospectus supplement.

     Approximately 0.042% of the mortgage loans will be Buydown Mortgage Loans.

     No mortgage loan provides for deferred interest or negative amortization.

     Two mortgage loans, representing approximately 0.2% of the aggregate
principal balance of the mortgage loans, are Additional Collateral Loans. See
"The Trusts--the Mortgage Loans" in the prospectus.

     Included below is a table showing the Credit Scores for some mortgagors.
Credit Scores are obtained by many mortgage lenders in connection with mortgage
loan applications to help assess a borrower's credit-worthiness. In addition,
Credit Scores may be obtained by Residential Funding after the origination of a
mortgage loan if the seller does not provide to Residential Funding a Credit
Score. Credit Scores are obtained from credit reports provided by various credit
reporting organizations, each of which may employ differing computer models and
methodologies. The Credit Score is designed to assess a borrower's credit
history at a single point in time, using objective information currently on file
for the borrower at a particular credit reporting organization. Information
utilized to create a Credit Score may include, among other things, payment
history, delinquencies on accounts, levels of outstanding indebtedness, length
of credit history, types of credit, and bankruptcy experience. Credit Scores
range from approximately 350 to approximately 840, with higher scores indicating
an individual with a more favorable credit history compared to an individual
with a lower score. However, a Credit Score purports only to be a measurement of
the relative degree of risk a borrower represents to a lender, i.e., a borrower
with a higher score is statistically expected to be less likely to default in
payment than a borrower with a lower score. In addition, it should be noted that
Credit Scores were developed to indicate a level of default probability over a
two-year period, which does not correspond to the life of a mortgage loan.
Furthermore, Credit Scores were not developed specifically for use in connection
with mortgage loans, but for consumer loans in general, and assess only the
borrower's past credit history. Therefore, a Credit Score does not take into
consideration the differences between mortgage loans and consumer loans
generally, or the specific characteristics of the related mortgage loan, for
example, the LTV ratio, the collateral for the mortgage loan, or the debt to
income ratio. There can be no assurance that the Credit Scores of the mortgagors
will be an accurate predictor of the likelihood of repayment of the related
mortgage loans or that any mortgagor's Credit Score would not be lower if
obtained as of the date of this prospectus supplement.

     The weighted average LTV ratio at origination of the mortgage loans which
were underwritten under a reduced loan documentation program will be 65.68%. No
more than 47.2% of such reduced loan documentation mortgage loans will be
secured by mortgaged properties located in California.

     0.9% of the mortgage loans were underwritten pursuant to a streamlined
refinancing documentation program, which permits mortgage loans to be refinanced
with only limited verification or updating of underwriting information obtained
at the time that the refinanced mortgage loan was underwritten. See "Mortgage
Loan Program--Underwriting Standards" in the prospectus.

     0.2% of the mortgage loans were underwritten pursuant to a modification
program after their respective original dates of origination in order to reduce
their respective mortgage rates without updated underwriting information. See
"Mortgage Loan Program--Underwriting Standards" in the prospectus.

PRIMARY MORTGAGE INSURANCE AND PRIMARY HAZARD INSURANCE

     Each mortgage loan is required to be covered by a standard hazard insurance
policy, which is referred to as a primary hazard insurance policy, except with
respect to two mortgage loans representing approximately 0.2% of the aggregate
principal balance of the mortgage loans. In addition, to the best of the
depositor's knowledge, each mortgage loan with an LTV ratio at origination in
excess of 80% will be insured by a primary mortgage insurance policy, which is
referred to as a primary insurance policy, covering at least 30% of the
principal balance of the mortgage loan at origination if the LTV ratio is
between 95.00% and 90.01%, at least 25% of the balance if the LTV ratio is
between 90.00% and 85.01% and at least 12% of the balance if the LTV ratio is
between 85.00% and 80.01%.

     Substantially all of the primary insurance policies were issued by General
Electric Mortgage Insurance Corporation, Mortgage Guaranty Insurance
Corporation, Triad Guaranty, United Guaranty Residential Insurance Company, PMI
Mortgage Insurance Company, Commonwealth Mortgage Assurance Company, Republic
Mortgage Insurance Company or Amerin Guaranty Corporation, which collectively
are the primary insurers. Each primary insurer has a claims paying ability
currently acceptable to the rating agencies that have been requested to rate the
certificates; however, there is no assurance as to the actual ability of any
primary insurer to pay claims. See "Insurance Policies on Mortgage Loans" in the
prospectus.

ADDITIONAL INFORMATION

     The description in this prospectus supplement of the mortgage pool and the
mortgaged properties is based upon the mortgage pool as constituted at the close
of business on the cut-off date, as adjusted for the scheduled principal
payments due on or before the cut-off date. Prior to the issuance of the offered
certificates, mortgage loans may be removed from the mortgage pool as a result
of incomplete documentation or otherwise, if the depositor deems that removal
necessary or appropriate. A limited number of other mortgage loans may be added
to the mortgage pool prior to the issuance of the offered certificates. The
depositor believes that the information in this prospectus supplement will be
substantially representative of the characteristics of the mortgage pool as it
will be constituted at the time the offered certificates are issued although the
range of mortgage rates and maturities and some other characteristics of the
mortgage loans in the mortgage pool may vary.

     A current report on Form 8-K will be available to purchasers of the offered
certificates and will be filed, together with the pooling and servicing
agreement, with the Securities and Exchange Commission within fifteen days after
the initial issuance of the offered certificates. In the event mortgage loans
are removed from or added to the mortgage pool as described in the preceding
paragraph, that removal or addition will be noted in the current report.

                        DESCRIPTION OF THE CERTIFICATES

GENERAL

     The Series 1999-S18 Mortgage Pass-Through Certificates will include the
following twelve classes of Senior Certificates:

     o Class A-1 Certificates

     o Class A-2 Certificates

     o Class A-3 Certificates

     o Class A-4 Certificates

     o Class A-5 Certificates

     o Class A-6 Certificates

     o Class A-7 Certificates, or the Floater Certificates

     o Class A-8 Certificates, or the Inverse Floater Certificates; and together
       with the Floater Certificates, the Adjustable Rate Certificates

     o Class A-9 Certificates, or the Lockout Certificates

     o Class A-P Certificates, or the Principal Only Certificates

     In addition to the Senior Certificates, the Series 1999-S18 Mortgage
Pass-Through Certificates will also include six classes of subordinate
certificates which are designated as the Class M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates, Class B-1 Certificates, Class B-2
Certificates and Class B-3 Certificates. Only the Senior Certificates and
Class M Certificates are offered hereby. See "Index of Principal Definitions" in
the prospectus for the meanings of capitalized terms and acronyms not otherwise
defined in this prospectus supplement.

     The certificates will evidence the entire beneficial ownership interest in
the trust. The trust will consist of:

     o the mortgage loans

     o the assets as from time to time that are identified as deposited in
       respect of the mortgage loans in the Custodial Account and in the
       Certificate Account and belonging to the trust

     o property acquired by foreclosure of the mortgage loans or deed in lieu of
       foreclosure

     o any applicable primary insurance policies and primary hazard insurance
       policies; and

     o all proceeds of any of the foregoing.

     The Senior Certificates will evidence in the aggregate an initial
beneficial ownership interest of approximately 95.75% in the trust. The
Class M-1, Class M-2, Class M-3, Class B-1, Class B-2 and Class B-3 Certificates
will each evidence in the aggregate an initial beneficial ownership interest of
approximately 2.35%, 0.75%, 0.45%, 0.30%, 0.20% and 0.20%, respectively, in the
trust.

     The Senior Certificates, other than the Principal Only, Variable Strip and
Residual Certificates, and the Class M Certificates will be available only in
book-entry form through facilities of The Depository Trust Company, and are
collectively referred to as the DTC registered certificates. The DTC registered
certificates will be issued, maintained and transferred on the book-entry
records of DTC and its participants. The DTC registered certificates will be
issued in minimum denominations of $25,000, or $250,000 in the case of the
Class M-2 Certificates and Class M-3 Certificates, and integral multiples of $1
in excess thereof. The Principal Only Certificates will be issued in registered,
certificated form in minimum denominations of $25,000 and integral multiples of
$1,000 in excess thereof, except for one Principal Only Certificate evidencing
the sum of an authorized denomination thereof and the remainder of the aggregate
initial Certificate Principal Balance of such class of certificates. The
Variable Strip Certificates and Residual Certificates will be issued in
registered, certificated form in minimum denominations of a 20% percentage
interest, except, in the case of one Class R

                                      S-21

Certificate, as otherwise described in this prospectus supplement under
"Material Federal Income Tax Consequences."

     The DTC registered certificates will be represented by one or more
certificates registered in the name of the nominee of DTC. The depositor has
been informed by DTC that DTC's nominee will be Cede & Co. No beneficial owner
will be entitled to receive a certificate of any class in fully registered form,
a definitive certificate, except as described in this prospectus supplement
under "--Book-Entry Registration of Certain of the Senior
Certificates--Definitive Certificates." Unless and until definitive certificates
are issued for the DTC registered certificates under the limited circumstances
described in this prospectus supplement:

     o all references to actions by certificateholders with respect to the DTC
       registered certificates shall refer to actions taken by DTC upon
       instructions from its participants, and

     o all references in this prospectus supplement to distributions, notices,
       reports and statements to certificateholders with respect to the DTC
       registered certificates shall refer to distributions, notices, reports
       and statements to DTC or Cede, as the registered holder of the DTC
       registered certificates, for distribution to beneficial Owners by DTC in
       accordance with DTC procedures.

     DTC has advised the depositor that management of DTC is aware that some
computer applications, systems and the like for processing data that are
dependent upon calendar dates, including dates before, on and after January 1,
2000, may encounter Y2K problems. DTC has informed its participants and other
members of the financial community, that it has developed and is implementing a
program so that its systems, as they relate to DTC services like the timely
payment of distributions, including principal and income payments, to
securityholders, book-entry deliveries and settlement of trades with DTC,
continue to function appropriately. This program includes a technical assessment
and a remediation plan, each of which is complete. Additionally, DTC's plan
includes a testing phase, which, DTC has advised its participants, is expected
to be completed within appropriate time frames.

     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as DTC's participants and third party vendors from whom DTC licenses
software and hardware, and third party vendors on whom DTC relies for
information or the provision of services, including telecommunication and
electrical utility service providers, among others. DTC has informed its
participants that it is contacting and will continue to contact third party
vendors from whom DTC acquires services to:

     o impress upon them the importance of those services being Y2K compliant;
       and

     o determine the extent of their efforts for Y2K remediation and, as
       appropriate, testing of their services.

     In addition, DTC is in the process of developing any contingency plans as
it deems appropriate.

     According to DTC, the foregoing information with respect to DTC has been
provided for informational purposes only and is not intended to serve as a
representation, warranty or contract modification of any kind.

BOOK-ENTRY REGISTRATION OF CERTAIN OF THE OFFERED CERTIFICATES

     General.  Beneficial owners that are not participants or indirect
participants but desire to purchase, sell or otherwise transfer ownership of, or
other interests in, the related DTC registered certificates may do so only
through participants and indirect participants. In addition, beneficial owners
will receive all distributions of principal of and interest on the related DTC
registered certificates from the paying agent through DTC and participants.
Accordingly, beneficial owners may experience delays in their receipt of
payments. Unless and until definitive certificates are issued for the related
DTC registered certificates, it is anticipated that the only registered
certificateholder of the DTC registered certificates will be Cede, as nominee of
DTC. Beneficial owners will not be recognized by the trustee or the master
servicer as certificateholders, as the term is used in the pooling and servicing
agreement, and beneficial owners will be permitted to receive information
furnished to certificateholders and to exercise the rights of certificateholders
only indirectly through DTC, its participants and indirect participants.

     Under the rules, regulations and procedures creating and affecting DTC and
its operations, DTC is required to make book-entry transfers of DTC registered
certificates among participants and to receive and transmit distributions of
principal of, and interest on, the DTC registered certificates. Participants and
indirect participants

                                      S-22

<PAGE>

with which beneficial owners have accounts with respect to the DTC registered
certificates similarly are required to make book-entry transfers and receive and
transmit distributions on behalf of their respective beneficial owners.
Accordingly, although beneficial owners will not possess physical certificates
evidencing their interests in the DTC registered certificates, DTC's rules
provide a mechanism by which beneficial owners, through their participants and
indirect participants, will receive distributions and will be able to transfer
their interests in the DTC registered certificates.

     None of the depositor, the master servicer or the trustee will have any
liability for any actions taken by DTC or its nominee, including, without
limitation, actions for any aspect of the records relating to or payments made
on account of beneficial ownership interests in the DTC registered certificates
held by Cede, as nominee for DTC, or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

     Definitive Certificates.  Definitive certificates will be issued to
beneficial owners or their nominees, respectively, rather than to DTC or its
nominee, only under the limited conditions described in the prospectus under
"Description of the Certificates--Form of Certificates."

     Upon the occurrence of an event described in the prospectus in the third
paragraph under "Description of the Certificates--Form of Certificates," the
trustee is required to notify, through DTC, participants who have ownership of
DTC registered certificates as indicated on the records of DTC of the
availability of definitive certificates for their DTC registered certificates.
Upon receipt of instructions from DTC for re-registration, the trustee will
reissue the DTC registered certificates as definitive certificates issued in the
respective principal amounts owned by individual beneficial owners, and
thereafter the trustee and the master servicer will recognize the holders of the
definitive certificates as certificateholders under the pooling and servicing
agreement.

     For additional information regarding DTC and the DTC registered
certificates, see "Description of the Certificates--Form of Certificates" in the
prospectus.

GLOSSARY OF TERMS

     The following terms are given the meanings shown below to help describe the
cash flows on the certificates:

     ACCRUED CERTIFICATE INTEREST--With respect to any distribution date, an
amount equal to (a) in the case of each class of offered certificates, other
than the Variable Strip Certificates and Principal Only Certificates, interest
accrued during the related Interest Accrual Period on the Certificate Principal
Balance of the certificates of that class immediately prior to that distribution
date at the related pass-through rate and (b) in the case of the Variable Strip
Certificates, interest accrued during the related Interest Accrual Period on the
related Notional Amount immediately prior to that distribution date at the
then-applicable pass-through rate on that class for that distribution date; in
each case less interest shortfalls, if any, allocated thereto for that
distribution date to the extent not covered with respect to the Senior
Certificates by the subordination provided by the Class B Certificates and
Class M Certificates and, with respect to the Class M Certificates to the extent
not covered by the subordination provided by the Class B Certificates and any
class or classes of Class M Certificates having a lower payment priority,
including in each case:

          (i) any Prepayment Interest Shortfall to the extent not covered by the
     master servicer as described in this prospectus supplement under
     "Description of the Certificates--Interest Distributions";

          (ii) the interest portions of Realized Losses, including Excess
     Special Hazard Losses, Excess Fraud Losses, Excess Bankruptcy Losses, and
     Extraordinary Losses not allocated through subordination;

          (iii) the interest portion of any Advances that were made with respect
     to delinquencies that were ultimately determined to be Excess Special
     Hazard Losses, Excess Fraud Losses, Excess Bankruptcy Losses or
     Extraordinary Losses; and

          (iv) any other interest shortfalls not covered by subordination,
     including interest shortfalls relating to the Soldiers' and Sailors' Civil
     Relief Act of 1940, or Relief Act, or similar legislation or regulations,
     all allocated as described below.

Any reductions will be allocated among the holders of all classes of
certificates in proportion to the respective amounts of Accrued Certificate
Interest that would have been payable on that distribution date absent these
reductions. In the case of each class of Class M Certificates, Accrued
Certificate Interest on that class will be further reduced by the allocation of
the interest portion of certain losses thereto, if any, as described below under

                                      S-23

<PAGE>

"--Allocation of Losses; Subordination." Accrued Certificate Interest on each
class of Senior Certificates will be distributed on a pro rata basis. Accrued
Certificate Interest on each class of certificates is calculated on the basis of
a 360-day year consisting of twelve 30-day months.

     AVAILABLE DISTRIBUTION AMOUNT--For any distribution date, an amount equal
to:

     o the aggregate amount of scheduled payments on the mortgage loans due on
       the related due date and received on or prior to the related
       determination date, after deduction of the related master servicing fees
       and any subservicing fees, which are collectively referred to as the
       servicing fees,

     o all unscheduled payments, including mortgagor prepayments on the mortgage
       loans, Insurance Proceeds, Liquidation Proceeds and proceeds from
       repurchases of and substitutions for the mortgage loans occurring during
       the preceding calendar month and

     o all Advances made for that distribution date, in each case net of amounts
       reimbursable therefrom to the master servicer and any subservicer.

     In addition to the foregoing amounts, with respect to unscheduled
collections, not including mortgagor prepayments, the master servicer may elect
to treat such amounts as included in the Available Distribution Amount for the
distribution date in the month of receipt, but is not obligated to do so. As
described in this prospectus supplement under "--Principal Distributions on the
Senior Certificates," any amount with respect to which such election is so made
shall be treated as having been received on the last day of the preceding
calendar month for the purposes of calculating the amount of principal and
interest distributions to any class of certificates. With respect to any
distribution date, the due date is the first day of the month in which that
distribution date occurs and the determination date is the 20th day of the month
in which that distribution date occurs or, if that day is not a business day,
the immediately succeeding business day.

     CERTIFICATE PRINCIPAL BALANCE--For any offered certificate as of any date
of determination, an amount equal to the initial Certificate Principal Balance
of that certificate, reduced by the aggregate of (a) all amounts allocable to
principal previously distributed with respect to that certificate and (b) any
reductions in the Certificate Principal Balance of that certificate deemed to
have occurred in connection with allocations of Realized Losses in the manner
described in this prospectus supplement, provided that, after the Certificate
Principal Balances of the Class B Certificates have been reduced to zero, the
Certificate Principal Balance of any certificate of the class of Class M
Certificates outstanding with the lowest payment priority shall equal the
percentage interest evidenced thereby multiplied by the excess, if any, of
(i) the then-aggregate Stated Principal Balance of all of the mortgage loans
over (ii) the then-aggregate Certificate Principal Balance of all other classes
of certificates then outstanding.

     CLASS M PERCENTAGE--With respect to the Class M-1, Class M-2 and Class M-3
Certificates and any distribution date, a percentage initially equal to
approximately 2.37%, 0.76% and 0.45%, respectively, and each will in no event
exceed 100%. The Class M-1, Class M-2, and Class M-3 Percentage will each be
adjusted for each distribution date to be the percentage equal to the
Certificate Principal Balance of the related class of Class M Certificates
immediately prior to that distribution date divided by the aggregate Stated
Principal Balance of all of the mortgage loans, other than the related Discount
Fraction of each Discount Mortgage Loan, immediately prior to that distribution
date. The initial Class M-1, Class M-2 and Class M-3 Percentages are greater
than the initial percentage interests in the trust evidenced by the Class M-1,
Class M-2 and Class M-3 Certificates, respectively, because the Class M-1,
Class M-2 and Class M-3 Percentages are calculated without regard to the
Discount Fraction of the Stated Principal Balance of each Discount Mortgage
Loan.

     CREDIT SUPPORT DEPLETION DATE--The first distribution date on which the
Senior Percentage equals 100%.

     DISCOUNT FRACTION--With respect to each Discount Mortgage Loan, a fraction,
expressed as a percentage, the numerator of which is 7.00% minus the Net
Mortgage Rate for such Discount Mortgage Loan and the denominator of which is
7.00%. The Principal Only Certificates will be entitled to payments based on the
Discount Fraction of the Discount Mortgage Loans.

     DISCOUNT MORTGAGE LOAN--Any mortgage loan with a Net Mortgage Rate less
than 7.00% per annum.

     ELIGIBLE FUNDS--On any distribution date, the portion, if any, of the
Available Distribution Amount remaining after reduction by the sum of the Senior
Interest Distribution Amount, the Senior Principal Distribution Amount,
determined without regard to clause (iv) of its definition, the Principal Only
Distribution

                                      S-24

<PAGE>

Amount, determined without regard to clause (v) of its definition and the
aggregate amount of Accrued Certificate Interest on the Class M, Class B-1 and
Class B-2 Certificates.

     EXCESS BANKRUPTCY LOSSES--Bankruptcy Losses in excess of the Bankruptcy
Amount.

     EXCESS FRAUD LOSSES--Fraud Losses in excess of the Fraud Loss Amount.

     EXCESS SPECIAL HAZARD LOSSES--Special Hazard Losses in excess of the
Special Hazard Amount.

     EXCESS SUBORDINATE PRINCIPAL AMOUNT--With respect to any distribution date
on which the Certificate Principal Balance of the most subordinate class or
classes of certificates then outstanding is to be reduced to zero and on which
Realized Losses are to be allocated to that class or those classes, the amount,
if any, by which (i) the amount of principal that would otherwise be
distributable on that class or those classes of certificates on that
distribution date is greater than (ii) the excess, if any, of the aggregate
Certificate Principal Balance of that class or those classes of certificates
immediately prior to that distribution date over the aggregate amount of
Realized Losses to be allocated to that class or those classes of certificates
on that distribution date, as reduced by any amount calculated pursuant to
clause (v) of the definition of "Principal Only Distribution Amount."

     FINAL DISPOSITION--With respect to a defaulted mortgage loan, a Final
Disposition is deemed to have occurred upon a determination by the master
servicer that it has received all Insurance Proceeds, Liquidation Proceeds and
other payments or cash recoveries which the master servicer reasonably and in
good faith expects to be finally recoverable with respect to the mortgage loan.

     INTEREST ACCRUAL PERIOD--For all classes of certificates, other than the
Adjustable Rate Certificates, the calendar month preceding the month in which
the distribution date occurs. The Interest Accrual Period for the Adjustable
Rate Certificates is the one-month period commencing on the 25th day of the
month preceding the month in which the distribution date occurs and ending on
the 24th day of the month in which the distribution date occurs. In spite of the
foregoing, the distributions of interest on any distribution date for all
classes of certificates, including the Adjustable Rate Certificates, will
reflect interest accrued, and receipts for that interest accrued, on the
mortgage loans for the preceding calendar month, as may be reduced by any
Prepayment Interest Shortfall and other shortfalls in collections of interest to
the extent described in this prospectus supplement.

     LOCKOUT SCHEDULED PERCENTAGE--For any distribution date occurring prior to
the distribution date in September 2004, 0%, and for any subsequent distribution
date, 100%.

     LOCKOUT PREPAYMENT PERCENTAGE--For any distribution date occurring prior to
the distribution date in September 2004, 0%. For any distribution date occurring
after the first five years following the closing date, a percentage determined
as follows:

     o for any distribution date during the sixth year after the closing date,
       30%

     o for any distribution date during the seventh year after the closing date,
       40%

     o for any distribution date during the eighth year after the closing date,
       60%

     o for any distribution date during the ninth year after the closing date,
       80%; and

     o for any distribution date thereafter, 100%.

     NON-DISCOUNT MORTGAGE LOAN--The mortgage loans other than the Discount
Mortgage Loans.

     NOTIONAL AMOUNT--As of any date of determination, the Notional Amount of
the Variable Strip Certificates is equal to the aggregate Stated Principal
Balance of the mortgage loans immediately prior to that date. Reference to a
Notional Amount with respect to any Variable Strip Certificate is solely for
convenience in specific calculations and does not represent the right to receive
any distributions allocable to principal.

     PRINCIPAL ONLY COLLECTION SHORTFALL--With respect to each Final Disposition
of a Discount Mortgage Loan in connection with that distribution date or any
prior distribution date, the extent that the amount included under clause
(iii) of the definition of Principal Only Distribution Amount for that
distribution date was less than the amount described in (a) under clause
(iii) of the definition of Principal Only Distribution Amount. Notwithstanding
any other provision of this prospectus supplement, any distribution relating to
any Principal Only Collection Shortfall, to the extent not covered by any
amounts otherwise distributable to the Class B-3 Certificates, shall result in a
reduction of the amount of principal distributions on that distribution date on
(i) first,

                                      S-25

<PAGE>

the Class B-1 Certificates and Class B-2 Certificates and (ii) second, the
Class M Certificates, in each case in reverse order of their payment priority.

     PRINCIPAL ONLY DISTRIBUTION AMOUNT--On each distribution date, a
distribution allocable to principal made to holders of the Principal Only
Certificates equal to the Available Distribution Amount remaining after the
Senior Interest Distribution Amount is distributed, equal to the aggregate of:

          (i) the related Discount Fraction of the principal portion of the
     scheduled monthly payment on each Discount Mortgage Loan due on the related
     due date, whether or not received on or prior to the related determination
     date, less the Discount Fraction of the principal portion of any related
     Debt Service Reductions which together with other Bankruptcy Losses are in
     excess of the Bankruptcy Amount;

          (ii) the related Discount Fraction of the principal portion of all
     unscheduled collections on each Discount Mortgage Loan received during the
     preceding calendar month, other than amounts received in connection with a
     Final Disposition of a Discount Mortgage Loan described in clause
     (iii) below, including full and partial mortgagor prepayments, repurchases
     of Discount Mortgage Loans or, in the case of a substitution, amounts
     representing a principal adjustment, as required by the pooling and
     servicing agreement, Liquidation Proceeds and Insurance Proceeds, to the
     extent applied as recoveries of principal;

          (iii) in connection with the Final Disposition of a Discount Mortgage
     Loan that did not result in any Excess Special Hazard Losses, Excess Fraud
     Losses, Excess Bankruptcy Losses or Extraordinary Losses, an amount equal
     to the lesser of (a) the applicable Discount Fraction of the Stated
     Principal Balance of that Discount Mortgage Loan immediately prior to that
     distribution date and (b) the aggregate amount of collections on that
     Discount Mortgage Loan to the extent applied as recoveries of principal;

          (iv) any amounts allocable to principal for any previous distribution
     date calculated pursuant to clauses (i) through (iii) above that remain
     undistributed; and

          (v) an amount equal to the aggregate of the Principal Only Collection
     Shortfalls, less any amounts paid under this clause on a prior distribution
     date, until paid in full; provided, that distributions under this clause
     (v) shall only be made to the extent of Eligible Funds (as described in the
     definition of Eligible Funds) on any distribution date.

     SENIOR ACCELERATED DISTRIBUTION PERCENTAGE--For any distribution date
occurring prior to the distribution date in September 2004, 100%. The Senior
Accelerated Distribution Percentage for any distribution date occurring after
the first five years following the closing date will be as follows:

     o for any distribution date during the sixth year after the closing date,
       the Senior Percentage for that distribution date plus 70% of the
       Subordinate Percentage for that distribution date

     o for any distribution date during the seventh year after the closing date,
       the Senior Percentage for that distribution date plus 60% of the
       Subordinate Percentage for that distribution date

     o for any distribution date during the eighth year after the closing date,
       the Senior Percentage for that distribution date plus 40% of the
       Subordinate Percentage for that distribution date

     o for any distribution date during the ninth year after the closing date,
       the Senior Percentage for that distribution date plus 20% of the
       Subordinate Percentage for that distribution date; and

     o for any distribution date thereafter, the Senior Percentage for that
       distribution date.

     If on any distribution date the Senior Percentage exceeds the initial
Senior Percentage, the Senior Accelerated Distribution Percentage for that
distribution date will once again equal 100%.

     Any scheduled reduction to the Senior Accelerated Distribution Percentage
shall not be made as of any distribution date unless either:

          (a)(i)(X) the outstanding principal balance of mortgage loans
     delinquent 60 days or more averaged over the last six months, as a
     percentage of the aggregate outstanding Certificate Principal Balance of
     the Class M Certificates and Class B Certificates, is less than 50% or
     (Y) the outstanding principal balance of mortgage loans delinquent 60 days
     or more averaged over the last six months, as a percentage of the aggregate
     outstanding principal balance of all mortgage loans averaged over the last
     six months, does not exceed 2%, and

                                      S-26

<PAGE>

          (ii) Realized Losses on the mortgage loans to date for that
     distribution date, if occurring during the sixth, seventh, eighth, ninth or
     tenth year, or any year thereafter, after the closing date, are less than
     30%, 35%, 40%, 45% or 50%, respectively, of the sum of the initial
     Certificate Principal Balances of the Class M Certificates and Class B
     Certificates; or

          (b)(i) the outstanding principal balance of mortgage loans delinquent
     60 days or more averaged over the last six months, as a percentage of the
     aggregate outstanding principal balance of all mortgage loans averaged over
     the last six months, does not exceed 4%, and

          (ii) Realized Losses on the mortgage loans to date for that
     distribution date, if occurring during the sixth, seventh, eighth, ninth or
     tenth year, or any year thereafter, after the Closing Date, are less than
     10%, 15%, 20%, 25% or 30%, respectively, of the sum of the initial
     Certificate Principal Balances of the Class M Certificates and Class B
     Certificates.

     Notwithstanding the foregoing, upon reduction of the Certificate Principal
Balances of the Senior Certificates, other than the Principal Only Certificates,
to zero, the Senior Accelerated Distribution Percentage will equal 0%.

     SENIOR INTEREST DISTRIBUTION AMOUNT--The aggregate amount of Accrued
Certificate Interest to be distributed to the holders of the Senior Certificates
for that Distribution Date.

     SENIOR PERCENTAGE--As of each distribution date, the percentage equal to
the aggregate Certificate Principal Balance of the Senior Certificates, other
than the Principal Only Certificates, immediately prior to that distribution
date divided by the aggregate Stated Principal Balance of all of the mortgage
loans, other than the Discount Fraction of the Discount Mortgage Loans,
immediately prior to that distribution date. The Senior Percentage will
initially equal approximately 95.71% and will in no event exceed 100%. The
initial Senior Percentage is less than the initial percentage interest in the
trust evidenced by the Senior Certificates in the aggregate because that
percentage is calculated without regard to either the Certificate Principal
Balance of the Principal Only Certificates or the Discount Fraction of the
Stated Principal Balance of each Discount Mortgage Loan.

     SENIOR PRINCIPAL DISTRIBUTION AMOUNT--With respect to any distribution
date, the lesser of (a) the balance of the Available Distribution Amount
remaining after the Senior Interest Distribution Amount and Principal Only
Distribution Amount have been distributed and (b) the sum of:

          (i) the product of (A) the then-applicable Senior Percentage and
     (B) the aggregate of the following amounts:

             (1) the principal portion of all scheduled monthly payments on the
        mortgage loans, other than the related Discount Fraction of the
        principal portion of those payments, with respect to each Discount
        Mortgage Loan, due on the related due date, whether or not received on
        or prior to the related determination date, less the principal portion
        of Debt Service Reductions, other than the related Discount Fraction of
        the principal portion of the Debt Service Reductions with respect to
        each Discount Mortgage Loan, which together with other Bankruptcy Losses
        are in excess of the Bankruptcy Amount;

             (2) the principal portion of all proceeds of the repurchase of a
        mortgage loan or, in the case of a substitution, amounts representing a

             (3) the principal portion of all other unscheduled collections
        received during the preceding calendar month, other than full and
        partial mortgagor prepayments and any amounts received in connection
        with a Final Disposition of a mortgage loan described in clause

     (x) that occurred in the preceding calendar month and (y) that did not
     result in any Excess Special Hazard Losses, Excess Fraud Losses, Excess
     Bankruptcy Losses or Extraordinary Losses, an amount equal to the lesser
     of:

             (1) the then-applicable Senior Percentage of the Stated Principal
        Balance of the mortgage loan, other than the related Discount Fraction
        of the Stated Principal Balance, with respect to a Discount Mortgage
        Loan; and

          (iv) any Excess Subordinate Principal Amount for that distribution
     date; and

          (v) any amounts allocable to principal for any previous distribution
     date calculated pursuant to clauses (i) through (iii) above that remain
     undistributed to the extent that any of those amounts are not attributable
     to Realized Losses which were allocated to the Class M Certificates or
     Class B Certificates.

     SUBORDINATE PERCENTAGE--As of any date of determination a percentage equal
to 100% minus the Senior Percentage as of that date.

INTEREST DISTRIBUTIONS

     Holders of each class of Senior Certificates other than the Principal Only
Certificates will be entitled to receive interest distributions in an amount
equal to the Accrued Certificate Interest on that class on each distribution
date, to the extent of the Available Distribution Amount for that distribution
date, commencing on the first distribution date in the case of all classes of
Senior Certificates entitled to interest distributions.

     Holders of each class of Class M Certificates will be entitled to receive
interest distributions in an amount equal to the Accrued Certificate Interest on
that class on each distribution date, to the extent of the Available
Distribution Amount for that distribution date after distributions of interest
and principal to the Senior Certificates, reimbursements for some Advances to
the master servicer and distributions of interest and principal to any class of
Class M Certificates having a higher payment priority.

     The Principal Only Certificates are not entitled to distributions of
interest.

     Prepayment Interest Shortfalls will result because interest on prepayments
in full is distributed only to the date of prepayment, and because no interest
is distributed on prepayments in part, as these prepayments in part are applied
to reduce the outstanding principal balance of the related mortgage loans as of
the due date in the month of prepayment.

     However, with respect to any distribution date, any Prepayment Interest
Shortfalls resulting from prepayments in full during the preceding calendar
month will be offset by the master servicer, but only to the extent those
Prepayment Interest Shortfalls do not exceed an amount equal to the lesser of
(a) one-twelfth of 0.125% of the Stated Principal Balance of the mortgage loans
immediately preceding that distribution date and (b) the sum of the master
servicing fee payable to the master servicer for its master servicing activities
and reinvestment income received by the master servicer on amounts payable with
respect to that distribution date. Prepayment Interest Shortfalls resulting from
partial prepayments will not be offset by the master servicer from master
servicing compensation or otherwise. No assurance can be given that the master
servicing compensation available to cover Prepayment Interest Shortfalls will be
sufficient therefor. See "Pooling and Servicing Agreement--Servicing and Other
Compensation and Payment of Expenses" in this prospectus supplement.

     If on any distribution date the Available Distribution Amount is less than
Accrued Certificate Interest on the Senior Certificates for that distribution
date, the shortfall will be allocated among the holders of all classes of Senior
Certificates in proportion to the respective amounts of Accrued Certificate
Interest for that distribution date. In addition, the amount of any such
interest shortfalls that are covered by subordination, specifically, interest
shortfalls not described in clauses (i) through (iv) in the definition of
Accrued Certificate Interest, will be unpaid Accrued Certificate Interest and
will be distributable to holders of the certificates of those classes entitled
to those amounts on subsequent distribution dates, in each case to the extent of
available funds after interest distributions as required in this prospectus
supplement.

     These shortfalls could occur, for example, if delinquencies on the mortgage
loans were exceptionally high and were concentrated in a particular month and
Advances by the master servicer did not cover the shortfall. Any amounts so
carried forward will not bear interest. Any interest shortfalls will not be
offset by a reduction in the servicing compensation of the master servicer or
otherwise, except to the limited extent described in the preceding paragraph
with respect to Prepayment Interest Shortfalls resulting from prepayments in
full.

     The pass-through rates on all classes of offered certificates, other than
the Adjustable Rate, Variable Strip and Principal Only Certificates, are fixed
and are listed on pages S-4 and S-5 of this prospectus supplement.

     The pass-through rates on the Adjustable Rate Certificates are calculated
as follows:

          (1) The pass-through rate on the Class A-7 Certificates with respect
     to the initial Interest Accrual Period is 6.010% per annum, and as to any
     Interest Accrual Period thereafter, will be a per annum rate equal to 0.80%
     plus LIBOR, with a maximum rate of 9.00% per annum and a minimum rate of
     0.80% per annum.

          (2) The pass-through rate on the Class A-8 Certificates with respect
     to the initial Interest Accrual Period is 10.465% per annum, and as to any
     Interest Accrual Period thereafter, will be a per annum rate equal to
     28.70% minus the product of LIBOR and 3.5, with a maximum rate of 28.70%
     per annum and a minimum rate of 0.00% per annum.

     The pass-through rates on the Adjustable Rate Certificates for the current
and immediately preceding Interest Accrual Period may be obtained by telephoning
the trustee at (800) 524-9472.

                                      S-29

<PAGE>

     The pass-through rate on the Variable Strip Certificates on each
distribution date will equal the weighted average, as of the due date in the
month preceding the month in which that distribution date occurs, of the pool
strip rates on each of the mortgage loans in the mortgage pool. The pool strip
rate on any mortgage loan is equal to its Net Mortgage Rate minus 7.00%, but not
less than 0.00%. As of the cut-off date, the pool strip rates on the mortgage
loans range between 0.00% and 1.55% per annum. The initial pass-through rate on
the Variable Strip Certificates is 0.2950% per annum.

     As described in this prospectus supplement, the Accrued Certificate
Interest allocable to each class of certificates, other than the Principal Only
Certificates, which are not entitled to distributions of interest, is based on
the Certificate Principal Balance of that class or, in the case of the Variable
Strip Certificates, on the Notional Amount.

     At the option of the initial holder of the Variable Strip Certificates, any
Variable Strip Certificate can be exchanged by that holder for one or more
Variable Strip Certificates that represent, in the aggregate, the same Notional
Amount, and the pass-through rate and Notional Amount of each Variable Strip
Certificate so exchanged will be based on the pool strip rates and Stated
Principal Balances of the mortgage loans corresponding to that Variable Strip
Certificate.

DETERMINATION OF LIBOR

     LIBOR for any Interest Accrual Period after the initial Interest Accrual
Period will be determined as described in the three succeeding paragraphs.

     On each distribution date, LIBOR shall be established by the trustee and as
to any Interest Accrual Period, LIBOR will equal the rate for United States
dollar deposits for one month which appears on the Dow Jones Telerate Screen
Page 3750 as of 11:00 A.M., London time, on the second LIBOR Business Day prior
to the first day of that Interest Accrual Period--the LIBOR rate adjustment
date. Telerate Screen Page 3750 means the display designated as page 3750 on the
Telerate Service or any other page as may replace page 3750 on that service for
the purpose of displaying London interbank offered rates of major banks. If the
rate does not appear on that page or any other page as may replace that page on
that service, or if the service is no longer offered, any other service for
displaying LIBOR or comparable rates as may be selected by the trustee after
consultation with the master servicer, the rate will be the reference bank rate.

     The reference bank rate will be determined on the basis of the rates at
which deposits in U.S. Dollars are offered by the reference banks, which shall
be three major banks that are engaged in transactions in the London interbank
market, selected by the trustee after consultation with the master servicer. The
reference bank rate will be determined as of 11:00 A.M., London time, on the day
that is one LIBOR business day prior to the immediately preceding distribution
date to prime banks in the London interbank market for a period of one month in
amounts approximately equal to the aggregate Certificate Principal Balance of
the Adjustable Rate Certificates then outstanding. The trustee will request the
principal London office of each of the reference banks to provide a quotation of
its rate. If at least two quotations are provided, the rate will be the
arithmetic mean of the quotations. If on that date fewer than two quotations are
provided as requested, the rate will be the arithmetic mean of the rates quoted
by one or more major banks in New York City, selected by the trustee after
consultation with the master servicer, as of 11:00 A.M., New York City time, on
that date for loans in U.S. Dollars to leading European banks for a period of
one month in amounts approximately equal to the aggregate Certificate Principal
Balance of the Adjustable Rate Certificates then outstanding. If no quotations
can be obtained, the rate will be LIBOR for the prior distribution date, or in
the case of the first LIBOR rate adjustment date, 5.210% with respect to the
Adjustable Rate Certificates; provided however, if, under the priorities listed
previously in this paragraph, LIBOR for a distribution date would be based on
LIBOR for the previous distribution date for the third consecutive distribution
date, the trustee shall select an alternative comparable index over which the
trustee has no control, used for determining one-month Eurodollar lending rates
that is calculated and published or otherwise made available by an independent
party. LIBOR business day means any day other than (i) a Saturday or a Sunday or
(ii) a day on which banking institutions in the city of London, England are
required or authorized by law to be closed.

     The establishment of LIBOR by the trustee and the trustee's subsequent
calculation of the pass-through rates applicable to the Adjustable Rate
Certificates for the relevant Interest Accrual Period, in the absence of
manifest error, will be final and binding.

PRINCIPAL DISTRIBUTIONS ON THE SENIOR CERTIFICATES

     The holders of the Senior Certificates, other than the Variable Strip
Certificates which are not entitled to distributions of principal, will be
entitled to receive on each distribution date, in the priority described in this
prospectus supplement and to the extent of the portion of the Available
Distribution Amount remaining after the distribution of the Senior Interest
Distribution Amount is distributed, a distribution allocable to principal.

     Distributions of principal on the Senior Certificates on each distribution
date will be made, after distribution of the Senior Interest Distribution
Amount, as follows:

     (a) Prior to the occurrence of the Credit Support Depletion Date:

          (i) the Principal Only Distribution Amount shall be distributed to the
     Principal Only Certificates, in reduction of the Certificate Principal
     Balance thereof, until the Certificate Principal Balance thereof has been
     reduced to zero;

          (ii) the Senior Principal Distribution Amount shall be distributed to
     the Lockout Certificates in reduction of the Certificate Principal Balance
     thereof, in an amount equal to the sum of the following:

             (A) the Lockout Scheduled Percentage of the Lockout Certificates'
        pro rata share (based on the Certificate Principal Balance thereof
        relative to the aggregate Certificate Principal Balance of all classes
        of Certificates (other than the Principal Only Certificates)) of the
        aggregate of the collections described in clauses (i), (ii) and (v) of
        the definition of Senior Principal Distribution Amount without
        application of the Senior Percentage and Senior Accelerated Distribution
        Percentage; and

             (B) the Lockout Prepayment Percentage of the Lockout Certificates'
        pro rata share (based on the Certificate Principal Balance thereof
        relative to the aggregate Certificate Principal Balance of all classes
        of Certificates (other than the Principal Only Certificates)) of the
        aggregate of the collections described in clause (iii) of the definition
        of Senior Principal Distribution Amount without application of the
        Senior Accelerated Distribution Percentage;

        provided that, if the aggregate of the amounts set forth in
        clauses (i), (ii), (iii) and (v) of the definition of Senior Principal
        Distribution Amount is more than the balance of the Available
        Distribution Amount remaining after the Senior Interest Distribution
        Amount and the Principal Only Distribution Amount have been distributed,
        the amount paid to the Lockout Certificates pursuant to this
        clause (ii) shall be reduced by an amount equal to the Lockout
        Certificates' pro rata share (based on the aggregate Certificate
        Principal Balance thereof relative to the aggregate Certificate
        Principal Balance of the Senior Certificates (other than the Principal
        Only Certificates)) of such difference;

          (iii) the balance of the Senior Principal Distribution Amount
     remaining after the distributions, if any, described in clause (ii) above
     shall be distributed to the Class R Certificates, until the Certificate
     Principal Balance thereof has been reduced to zero;

          (iv) the balance of the Senior Principal Distribution Amount remaining
     after the distributions, if any, described in clauses (ii) and (iii) above
     shall be distributed concurrently as follows, until the Certificate
     Principal Balance of the Class A-3 Certificates has been reduced to zero:

             (A) 61.1151302191% to the Class A-1 Certificates;

             (B) 28.1879034566% to the Class A-2 Certificates; and

             (C) 10.6969663243% to the Class A-3 Certificates;

          (v) the balance of the Senior Principal Distribution Amount remaining
     after the distributions, if any, described in clauses (ii) through
     (iv) above shall be distributed concurrently as follows, until the
     Certificate Principal Balance of the Class A-2 Certificates has been
     reduced to zero:

             (A) 61.1151302191% to the Class A-1 Certificates;

             (B) 28.1879034566% to the Class A-2 Certificates; and

             (C) 10.6969663243% to the Class A-4 Certificates;

                                      S-31

<PAGE>

          (vi) the balance of the Senior Principal Distribution Amount remaining
     after the distributions, if any, described in clauses (ii) through
     (v) above shall be distributed concurrently as follows, until the
     Certificate Principal Balances thereof have been reduced to zero:

             (A) 61.1151302191% to the Class A-1 Certificates;

             (B) 10.6969663243% to the Class A-4 Certificates; and

             (C) 28.1879034566% to the Class A-5 Certificates;

          (vii) the balance of the Senior Principal Distribution Amount
     remaining after the distributions, if any, described in clauses (ii)
     through (vi) above shall be distributed to the Class A-6 Certificates,
     until the Certificate Principal Balance thereof has been reduced to zero;

          (viii) the balance of the Senior Principal Distribution Amount
     remaining after the distributions, if any, described in clauses (ii)
     through (vii) above shall be distributed, concurrently on a pro rata basis,
     to the Class A-7 Certificates and Class A-8 Certificates, until the
     Certificate Principal Balances thereof have been reduced to zero; and

          (ix) the balance of the Senior Principal Distribution Amount remaining
     after the distributions, if any, described in clauses (ii) through
     (viii) above shall be distributed to the Lockout Certificates, until the
     Certificate Principal Balance thereof has been reduced to zero.

     (b) On or after the occurrence of the Credit Support Depletion Date, all
priorities relating to distributions as described in clause (a) above relating
to principal among the Senior Certificates, other than the Principal Only
Certificates, will be disregarded. Instead, an amount equal to the Discount
Fraction of the principal portion of scheduled or unscheduled payments received
or advanced relating to Discount Mortgage Loans will be distributed to the
Principal Only Certificates, and the Senior Principal Distribution Amount will
be distributed to the Senior Certificates remaining pro rata in accordance with
their respective outstanding Certificate Principal Balances and the Senior
Interest Distribution Amount will be distributed as described under "Interest
Distributions."

     (c) After reduction of the Certificate Principal Balances of the Senior
Certificates, other than the Principal Only Certificates, to zero but prior to
the Credit Support Depletion Date, the Senior Certificates, other than the
Principal Only Certificates, will be entitled to no further distributions of
principal and the Available Distribution Amount will be paid solely to the
holders of the Principal Only, Variable Strip, Class M and Class B Certificates,
in each case as described in this prospectus supplement.

PRINCIPAL DISTRIBUTIONS ON THE CLASS M CERTIFICATES

     Holders of each class of the Class M Certificates will be entitled to
receive on each distribution date, to the extent of the portion of the Available
Distribution Amount remaining after:

     o the sum of the Senior Interest Distribution Amount, Principal Only
       Distribution Amount and Senior Principal Distribution Amount is
       distributed

     o reimbursement is made to the master servicer for some Advances remaining
       unreimbursed following the final liquidation of the related mortgage loan
       to the extent described below under "Advances"

     o the aggregate amount of Accrued Certificate Interest and principal
       required to be distributed to any class of Class M Certificates having a
       higher payment priority on that distribution date is distributed to
       holders of that class of Class M Certificates and

     o the aggregate amount of Accrued Certificate Interest required to be
       distributed to that class of Class M Certificates on that distribution
       date is distributed to those Class M Certificates, a distribution
       allocable to principal in the sum of the following:

          (i) the product of (A) the then-applicable related Class M Percentage
     and (B) the aggregate of the following amounts:

             (1) the principal portion of all scheduled monthly payments on the
        mortgage loans, other than the related Discount Fraction of the
        principal portion of those payments with respect to a Discount Mortgage
        Loan, due on the related due date, whether or not received on or prior
        to the related determination date, less the principal portion of Debt
        Service Reductions, other than the related

                                      S-32

<PAGE>

        Discount Fraction of the principal portion of the Debt Service
        Reductions with respect to a Discount Mortgage Loan, which together with
        other Bankruptcy Losses are in excess of the Bankruptcy Amount;

             (2) the principal portion of all proceeds of the repurchase of a
        mortgage loan or, in the case of a substitution, amounts representing a
        principal adjustment, other than the related Discount Fraction of the
        principal portion of the proceeds with respect to a Discount Mortgage
        Loan, as required by the pooling and servicing agreement during the
        preceding calendar month; and

             (3) the principal portion of all other unscheduled collections
        received during the preceding calendar month, other than full and
        partial mortgagor prepayments and any amounts received in connection
        with a Final Disposition of a mortgage loan described in clause
        (ii) below, to the extent applied as recoveries of principal, other than
        the related Discount Fraction of the principal amount of those
        unscheduled collections, with respect to a Discount Mortgage Loan;

          (ii) that class' pro rata share, based on the Certificate Principal
     Balance of each class of Class M Certificates and Class B Certificates then
     outstanding, of all amounts received in connection with the Final
     Disposition of a mortgage loan, other than the related Discount Fraction of
     those amounts with respect to a Discount Mortgage Loan, (x) that occurred
     during the preceding calendar month and (y) that did not result in any
     Excess Special Hazard Losses, Excess Fraud Losses, Excess Bankruptcy Losses
     or Extraordinary Losses, to the extent applied as recoveries of principal
     and to the extent not otherwise payable to the Senior Certificates;

          (iii) the portion of full and partial mortgagor prepayments, other
     than the Discount Fraction of those mortgagor prepayments with respect to a
     Discount Mortgage Loan, made by the respective mortgagors during the
     preceding calendar month allocable to that class of Class M Certificates as
     described in the third succeeding paragraph;

          (iv) if that class is the most senior class of certificates then
     outstanding, an amount equal to the Excess Subordinate Principal Amount, if
     any; and

          (v) any amounts allocable to principal for any previous distribution
     date calculated pursuant to clauses (i) through (iii) above that remain
     undistributed to the extent that any of those amounts are not attributable
     to Realized Losses which were allocated to any class of Class M
     Certificates with a lower payment priority or the Class B Certificates.

     References in this prospectus supplement to "payment priority" of the Class
M Certificates refer to a payment priority among those classes as follows:
first, to the Class M-1 Certificates; second, to the Class M-2 Certificates; and
third, to the Class M-3 Certificates.

     As to each class of Class M Certificates, on any distribution date, any
Accrued Certificate Interest thereon remaining unpaid from any previous
distribution date will be distributable to the extent of available funds.
Notwithstanding the foregoing, if the Certificate Principal Balances of the
Class B Certificates have been reduced to zero, on any distribution date, with
respect to the class of Class M Certificates outstanding on that distribution
date with the lowest payment priority, Accrued Certificate Interest thereon
remaining unpaid from any previous distribution date, except in the limited
circumstances provided in the pooling and servicing agreement, will not be
distributable.

     All mortgagor prepayments not otherwise distributable to the Senior
Certificates will be allocated on a pro rata basis among the class of Class M
Certificates with the highest payment priority then outstanding and each other
class of Class M Certificates and Class B Certificates for which certain loss
levels established for that class in the pooling and servicing agreement have
not been exceeded. The related loss level on any distribution date would be
satisfied as to any Class M-2, Class M-3 or Class B Certificates, respectively,
only if the sum of the current percentage interests in the mortgage pool
evidenced by that class and each class, if any, subordinate thereto were at
least equal to the sum of the initial percentage interests in the mortgage pool
evidenced by that class and each class, if any, subordinate thereto.

     As stated above under "--Principal Distributions on the Senior
Certificates," the Senior Accelerated Distribution Percentage will be 100%
during the first five years after the closing date, unless the Certificate
Principal Balances of the Senior Certificates, other than the Principal Only
Certificates, are reduced to zero before the end of that five-year period, and
will thereafter equal 100% whenever the Senior Percentage exceeds

                                      S-33

<PAGE>

the initial Senior Percentage. Furthermore, as described in this prospectus
supplement, the Senior Accelerated Distribution Percentage will exceed the
Senior Percentage during the sixth through ninth years following the closing
date, and scheduled reductions to the Senior Accelerated Distribution Percentage
may be postponed due to the loss and delinquency experience of the mortgage
loans. Accordingly, each class of the Class M Certificates will not be entitled
to any mortgagor prepayments for at least the first five years after the closing
date, unless the Certificate Principal Balances of the Senior Certificates
(other than the Principal Only Certificates) have been reduced to zero before
the end of such period, and may receive no mortgagor prepayments or a
disproportionately small portion of mortgagor prepayments relative to the
related Class M Percentage during certain periods after this five year period.
See "--Principal Distributions on the Senior Certificates" in this prospectus
supplement.

ALLOCATION OF LOSSES; SUBORDINATION

     The subordination provided to the Senior Certificates by the Class B
Certificates and Class M Certificates and the subordination provided to each
class of Class M Certificates by the Class B Certificates and by any class of
Class M Certificates subordinate thereto will cover Realized Losses on the
mortgage loans that are Defaulted Mortgage Losses, Fraud Losses, Bankruptcy
Losses and Special Hazard Losses. Any Realized Losses which are not Excess
Special Hazard Losses, Excess Fraud Losses, Excess Bankruptcy Losses or
Extraordinary Losses will be allocated as follows:

     o first, to the Class B Certificates

     o second, to the Class M-3 Certificates

     o third, to the Class M-2 Certificates; and

     o fourth, to the Class M-1 Certificates

in each case until the Certificate Principal Balance of that class of
certificates has been reduced to zero; and thereafter, if any Realized Loss is
on a Discount Mortgage Loan, to the Principal Only Certificates in an amount
equal to the related Discount Fraction of the principal portion of the Realized
Loss, and the remainder of the Realized Losses and the entire amount of Realized
Losses on Non-Discount Mortgage Loans among all the remaining classes of Senior
Certificates on a pro rata basis.

     Any allocation of a Realized Loss, other than a Debt Service Reduction, to
a certificate will be made by reducing:

     o its Certificate Principal Balance, in the case of the principal portion
       of the Realized Loss, in each case until the Certificate Principal
       Balance of that class has been reduced to zero, and

     o the Accrued Certificate Interest thereon, in the case of the interest
       portion of the Realized Loss, by the amount so allocated as of the
       distribution date occurring in the month following the calendar month in
       which the Realized Loss was incurred.

In addition, any allocation of a Realized Loss to a Class M Certificate may also
be made by operation of the payment priority to the Senior Certificates
described under "--Principal Distributions on the Senior Certificates" and any
class of Class M Certificates with a higher payment priority.

     As used in this prospectus supplement, subordination refers to the
provisions discussed above for the sequential allocation of Realized Losses
among the various classes, as well as all provisions effecting those allocations
including the priorities for distribution of cash flows in the amounts described
in this prospectus supplement.

     As described in the prospectus, in some circumstances the master servicer
may permit a servicing modification--the modification of a defaulted mortgage
loan to reduce the applicable mortgage rate or to reduce its outstanding
principal amount. Any principal reduction of this type shall constitute a
Realized Loss at the time of the reduction, and the amount by which each monthly
payment is reduced by any mortgage rate reduction shall constitute a Realized
Loss in the month in which each such reduced monthly payment is due.

     Servicing modification reductions shall be allocated when incurred (as
provided above) in the same manner as other Realized Losses as described in this
prospectus supplement. Any Advances made on any mortgage loan will be reduced to
reflect any related servicing modifications previously made. No servicing
modification will have the effect of reducing the mortgage rate below the sum of
the servicing fee rate and the pool strip rate as in effect at the cut-off date.
The mortgage rate and Net Mortgage Rate as to any mortgage loan will be deemed
not

                                      S-34

<PAGE>

reduced by any servicing modification, so that the calculation of Accrued
Certificate Interest payable on the offered certificates will not be affected by
the servicing modification.

     Allocations of the principal portion of Debt Service Reductions to each
class of Class M Certificates and Class B Certificates will result from the
priority of distributions of the Available Distribution Amount as described in
this prospectus supplement, which distributions shall be made first to the
Senior Certificates, second to the Class M Certificates in the order of their
payment priority and third to the Class B Certificates. An allocation of the
interest portion of a Realized Loss as well as the principal portion of Debt
Service Reductions will not reduce the level of subordination, as that term is
defined in this prospectus supplement, until an amount in respect thereof has
been actually disbursed to the Senior Certificateholders or the Class M
Certificateholders, as applicable.

     The holders of the offered certificates will not be entitled to any
additional payments with respect to Realized Losses from amounts otherwise
distributable on any classes of certificates subordinate thereto, except in
limited circumstances in respect of any Excess Subordinate Principal Amount, or
in the case of Principal Only Collection Shortfalls, to the extent of Eligible
Funds. Accordingly, the subordination provided to the Senior Certificates, other
than the Principal Only Certificates, and to each class of Class M Certificates
by the respective classes of certificates subordinate thereto with respect to
Realized Losses allocated on any distribution date will be effected primarily by
increasing the Senior Percentage, or the respective Class M Percentage, of
future distributions of principal of the remaining mortgage loans. Because the
Discount Fraction of each Discount Mortgage Loan will not change over time, the
protection from losses provided to the Principal Only Certificates by the Class
M Certificates and Class B Certificates is limited to the prior right of the
Principal Only Certificates to receive distributions in respect of principal as
described in this prospectus supplement. Furthermore, principal losses on the
mortgage loans that are not covered by subordination will be allocated to the
Principal Only Certificates only to the extent they occur on a Discount Mortgage
Loan and only to the extent of the related Discount Fraction of those losses.
The allocation of principal losses on the Discount Mortgage Loans may result in
those losses being allocated in an amount that is greater or less than would
have been the case had those losses been allocated in proportion to the
Certificate Principal Balance of the Principal Only Certificates. Thus, the
Senior Certificates, other than the Principal Only Certificates, will bear the
entire amount of losses that are not allocated to the Class M Certificates and
Class B Certificates, other than the amount allocable to the Principal Only
Certificates, which losses will be allocated among all classes of Senior
Certificates, other than the Principal Only Certificates, as described in this
prospectus supplement.

     Because the Principal Only Certificates are entitled to receive in
connection with the Final Disposition of a Discount Mortgage Loan, on any
distribution date, an amount equal to all unpaid Principal Only Collection
Shortfalls to the extent of Eligible Funds on that distribution date, shortfalls
in distributions of principal on any class of Class M Certificates could occur
under some circumstances, even if that class is not the most subordinate class
of certificates then outstanding.

     Any Excess Special Hazard Losses, Excess Fraud Losses, Excess Bankruptcy
Losses, Extraordinary Losses or other losses of a type not covered by
subordination on Non-Discount Mortgage Loans will be allocated on a pro rata
basis among the Senior Certificates, other than the Principal Only Certificates,
Class M Certificates and Class B Certificates. Any Realized Losses so allocated
to the Senior Certificates or Class M Certificates will be allocated without
priority among the various classes of Senior Certificates, other than the
Principal Only Certificates, or Class M Certificates. The principal portion of
these losses on Discount Mortgage Loans will be allocated to the Principal Only
Certificates in an amount equal to their related Discount Fraction, and the
remainder of the losses on Discount Mortgage Loans will be allocated among the
remaining certificates on a pro rata basis.

     An allocation of a Realized Loss on a "pro rata basis" among two or more
classes of certificates means an allocation to each of those classes of
certificates on the basis of its then outstanding Certificate Principal Balance
prior to giving effect to distributions to be made on that distribution date in
the case of an allocation of the principal portion of a Realized Loss, or based
on the Accrued Certificate Interest thereon in respect of that distribution date
in the case of an allocation of the interest portion of a Realized Loss.

     In order to maximize the likelihood of distribution in full of the Senior
Interest Distribution Amount, Principal Only Distribution Amount and Senior
Principal Distribution Amount, on each distribution date, holders of Senior
Certificates have a right to distributions of the Available Distribution Amount
that is prior to the rights

                                      S-35

<PAGE>

of the holders of the Class M Certificates and Class B Certificates, to the
extent necessary to satisfy the Senior Interest Distribution Amount, Principal
Only Distribution Amount and Senior Principal Distribution Amount. Similarly,
holders of the Class M Certificates have a right to distributions of the
Available Distribution Amount prior to the rights of holders of the Class B
Certificates, and holders of any class of Class M Certificates with a higher
payment priority have a right to distributions of the Available Distribution
Amount prior to the rights of holders of any class of Class M Certificates with
a lower payment priority.

     The application of the Senior Accelerated Distribution Percentage, when it
exceeds the Senior Percentage, to determine the Senior Principal Distribution
Amount will accelerate the amortization of the Senior Certificates, other than
the Principal Only Certificates, in the aggregate relative to the actual
amortization of the mortgage loans. The Principal Only Certificates will not
receive more than the Discount Fraction of any unscheduled payment relating to a
Discount Mortgage Loan. To the extent that the Senior Certificates in the
aggregate, other than the Principal Only Certificates, are amortized faster than
the mortgage loans, in the absence of offsetting Realized Losses allocated to
the Class M Certificates and Class B Certificates, the percentage interest
evidenced by the Senior Certificates in the trust will be decreased, with a
corresponding increase in the interest in the trust evidenced by the Class M and
Class B Certificates, thereby increasing, relative to their respective
Certificate Principal Balances, the subordination afforded the Senior
Certificates by the Class M Certificates and Class B Certificates collectively.
In addition, if losses on the mortgage loans exceed the amounts described in
this prospectus supplement under "--Principal Distributions on the Senior
Certificates," a greater percentage of full and partial mortgagor prepayments
will be allocated to the Senior Certificates in the aggregate, other than the
Principal Only Certificates, than would otherwise be the case, thereby
accelerating the amortization of the Senior Certificates relative to the Class M
and Class B Certificates.

     The priority of payments, including principal prepayments, among the Class
M Certificates, as described in this prospectus supplement, also has the effect
during some periods, in the absence of losses, of decreasing the percentage
interest evidenced by any class of Class M Certificates with a higher payment
priority, thereby increasing, relative to its Certificate Principal Balance, the
subordination afforded to that class of the Class M Certificates by the Class B
Certificates and any class of Class M Certificates with a lower payment
priority.

     The Special Hazard Amount shall initially be equal to $3,692,894. As of any
date of determination following the cut-off date, the Special Hazard Amount
shall equal $3,692,894 less the sum of (A) any amounts allocated through
subordination relating to Special Hazard Losses and (B) the Adjustment Amount.
The Adjustment Amount will be equal to an amount calculated under the terms of
the pooling and servicing agreement.

     The Fraud Loss Amount shall initially be equal to $3,692,894. As of any
date of determination after the cut-off date, the Fraud Loss Amount shall equal
(X) prior to the third anniversary of the cut-off date an amount equal to 1.00%
of the aggregate principal balance of all of the mortgage loans as of the
cut-off date minus the aggregate amounts allocated through Subordination with
respect to Fraud Losses up to that date of determination and (Y) from the third
to the fifth anniversary of the cut-off date, an amount equal to (1) the lesser
of (a) the Fraud Loss Amount as of the most recent anniversary of the cut-off
date and (b) 0.50% of the aggregate principal balance of all of the mortgage
loans as of the most recent anniversary of the cut-off date minus (2) the
aggregate amounts allocated through subordination with respect to Fraud Losses
since the most recent anniversary of the cut-off date up to that date of
determination. On and after the fifth anniversary of the cut-off date, the Fraud
Loss Amount shall be zero and Fraud Losses shall not be allocated through
subordination.

     The Bankruptcy Amount will initially be equal to $137,216. As of any date
of determination on or after the first anniversary of the cut-off date, the
Bankruptcy Amount will equal the excess, if any, of (1) the lesser of (a) the
Bankruptcy Amount as of the business day next preceding the most recent
anniversary of the cut-off date and (b) an amount calculated under the terms of
the pooling and servicing agreement, which amount as calculated will provide for
a reduction in the Bankruptcy Amount, over (2) the aggregate amount of
Bankruptcy Losses allocated solely to the Class M Certificates or Class B
Certificates through subordination since that anniversary.

     Notwithstanding the foregoing, the provisions relating to subordination
will not be applicable in connection with a Bankruptcy Loss so long as the
master servicer has notified the trustee in writing that:

     o the master servicer is diligently pursuing any remedies that may exist in
       connection with the representations and warranties made regarding the
       related mortgage loan and

                                      S-36

<PAGE>

     o either:

          o the related mortgage loan is not in default with regard to payments
            due thereunder or

          o delinquent payments of principal and interest under the related
            mortgage loan and any premiums on any applicable primary hazard
            insurance policy and any related escrow payments relating to that
            mortgage loan are being advanced on a current basis by the master
            servicer or a subservicer.

     The Special Hazard Amount, Fraud Loss Amount and Bankruptcy Amount may be
further reduced as described in the prospectus under "Subordination."

ADVANCES

     Prior to each distribution date, the master servicer is required to make
Advances which were due on the mortgage loans on the immediately preceding due
date and delinquent on the business day next preceding the related determination
date.

     These Advances are required to be made only to the extent they are deemed
by the master servicer to be recoverable from related late collections,
Insurance Proceeds, Liquidation Proceeds or amounts otherwise payable to the
holders of the Class B Certificates or Class M Certificates. The purpose of
making these Advances is to maintain a regular cash flow to the
certificateholders, rather than to guarantee or insure against losses. The
master servicer will not be required to make any Advances with respect to
reductions in the amount of the monthly payments on the mortgage loans due to
Debt Service Reductions or the application of the Relief Act or similar
legislation or regulations. Any failure by the master servicer to make an
Advance as required under the pooling and servicing agreement will constitute an
event of default thereunder, in which case the trustee, as successor master
servicer, will be obligated to make any Advance, in accordance with the terms of
the pooling and servicing agreement.

     All Advances will be reimbursable to the master servicer on a first
priority basis from either (a) late collections, Insurance Proceeds and
Liquidation Proceeds from the mortgage loan as to which such unreimbursed
Advance was made or (b) as to any Advance that remains unreimbursed in whole or
in part following the final liquidation of the related mortgage loan, from any
amounts otherwise distributable on any of the Class B Certificates or Class M
Certificates; provided, however, that any Advances that were made with respect
to delinquencies which ultimately were determined to be Excess Special Hazard
Losses, Excess Fraud Losses, Excess Bankruptcy Losses or Extraordinary Losses
are reimbursable to the master servicer out of any funds in the Custodial
Account prior to distributions on any of the certificates and the amount of
those losses will be allocated as described in this prospectus supplement.

     In addition, if the Certificate Principal Balances of the Class M
Certificates and Class B Certificates have been reduced to zero, any Advances
previously made which are deemed by the master servicer to be nonrecoverable
from related late collections, Insurance Proceeds and Liquidation Proceeds may
be reimbursed to the master servicer out of any funds in the Custodial Account
prior to distributions on the Senior Certificates. The effect of these
provisions on any class of the Class M Certificates is that, with respect to any
Advance which remains unreimbursed following the final liquidation of the
related mortgage loan, the entire amount of the reimbursement for that Advance
will be borne first by the holders of the Class B Certificates or any class of
Class M Certificates having a lower payment priority to the extent that the
reimbursement is covered by amounts otherwise distributable to those classes,
and then by the holders of that class of Class M Certificates (except as
provided above) to the extent of the amounts otherwise distributable to them.

                            YEAR 2000 CONSIDERATIONS

OVERVIEW OF THE YEAR 2000 ISSUE

     The Y2K issue is the term used to describe the potential failure of
information technology components on or after January 1, 2000 because existing
computer programs, applications and microprocessors frequently use only two
digits to identify a year. Since the Year 2000 is also a leap year, there could
be additional business disruptions as a result of the inability of many computer
systems to recognize February 29, 2000.

     The failure to correct or replace computer programs, applications and
microprocessors with Y2K-ready alternatives may adversely impact the operations
of Residential Funding at the turn of the century. The responsibilities of
Residential Funding as the master servicer include collecting payments from the
subservicers relating to the mortgage loans, calculating the Available
Distribution Amount for each distribution date, remitting that amount to the
trustee prior to each distribution date, calculating the amount of principal and
interest payments to be made to the certificateholders on each distribution
date, and preparing the monthly statement to be sent to certificateholders on
each distribution date.

OVERVIEW OF RESIDENTIAL FUNDING'S Y2K PROJECT

     In January 1997, Residential Funding commenced activities to determine the
impact of Y2K on its critical computer systems. In April 1998, Residential
Funding established a formal Y2K project team to address Y2K issues. The Y2K
project team remains in place and continues to work on solving problems related
to the Year 2000. In addition, the Y2K project team coordinates its efforts with
the Y2K programs established by General Motors Acceptance Corporation and
General Motors Corporation.

     Members of the Y2K project team, together with relevant personnel from
Residential Funding's business units have developed and implemented a six-phase
management strategy (as discussed below), which has been, and will be, applied
to information technology and non-information technology components throughout
the organization. Residential Funding's components primarily consist of the
following:

     o hardware, including mainframe computers, desktop computers and network
       devices;

     o facilities equipment, including elevators, telephone systems, heating
       systems and security systems;

     o software applications, including vendor purchased applications, in-house
       developed applications and end-user developed applications;

     o business partner communication links, which primarily provide data
       transmissions to and from business partners; and

     o business partners data systems, which primarily process data for
       Residential Funding.

                                      S-38

<PAGE>

     The six phases by which the Y2K project team has sought, and will seek, to
achieve Y2K readiness throughout Residential Funding are as follows:

<TABLE>
<CAPTION>
              PHASE                                              OBJECTIVE
- ----------------------------------  --------------------------------------------------------------------
<S>                                 <C>
Phase I--Awareness................  To promote Y2K awareness throughout Residential Funding. Emphasis
                                    has been placed on ensuring that components recently purchased or to
                                    be purchased by business units are Y2K-ready prior to the
                                    implementation of those components.

Phase II--Inventory...............  To create an inventory of all components and assess the Y2K risks
                                    associated with those components.

Phase III--Assessment.............  To determine which components are not Y2K-ready and decide whether
                                    those components should be replaced, retired or repaired.

Phase IV--Renovation..............  To execute component replacement, retirement or repair to ensure Y2K
                                    readiness.

Phase V--Validation...............  To test components that have been repaired to ensure Y2K readiness
                                    and validate "mission critical" components that were assessed as
                                    Y2K-ready in Phase III.

Phase VI--Implementation..........  To deploy repaired and validated components.
</TABLE>

     In order to execute the six-phase plan, a combination of internal resources
and external contractors has been, and will be, employed by the Y2K project
team.

Y2K PROJECT STATUS

     The Y2K project team has completed the six phases for its internal "mission
critical" components. Additionally, the Y2K project team has completed the
renovation and validation of any non-mission critical components that the Y2K
project team and related business units determined to be necessary. If
Residential Funding introduces or replaces, prior to January 1, 2000, any
"mission critical" components, the Y2K project team will ensure that the
components conform to the requirements of the above six-phase plan.

     The potential impact on Residential Funding of problems related to Y2K,
however, will not depend solely on the corrective measures undertaken by the Y2K
project team. The manner in which Y2K issues are addressed by business partners,
governmental agencies and other entities that provide data to, or receive data
from, Residential Funding, or whose financial condition or operational
capability is important to Residential Funding and its ability to act as master
servicer, will have a significant impact upon Residential Funding. These
entities include, among others, subservicers, the trustee, the custodian and
some depositary institutions, as well as their respective suppliers and vendors.
Accordingly, Residential Funding has communicated, and will continue to
communicate, with some of these parties to assess their Y2K readiness and
evaluate any potential impact on Residential Funding.

     Due to the various dates by which Residential Funding's business partners
anticipate being Y2K ready, it is expected that the Y2K project team will
continue to spend significant time assessing Y2K business partner issues
throughout 1999. Any business partner, including any subservicer, the trustee
and the custodian, that:

     o has not provided Residential Funding appropriate documentation supporting
       its Y2K efforts

     o has not responded in a timely manner to Residential Funding's inquiries
       regarding their Y2K efforts or

     o did not expect to be Y2K-ready until after June 30, 1999

has been, and will be, placed in an "at risk" category. Currently, only a very
limited number of subservicers have been placed in the "at-risk" category.
Residential Funding will carefully monitor the efforts and progress of its "at
risk" business partners, and if additional steps are necessary, Residential
Funding will reassess the risk and act accordingly.

                                      S-39

<PAGE>

     During 1998, Residential Funding also commenced a formal business
continuity plan that is designed to address potential Y2K problems and other
possible disruptions. Residential Funding's business continuity plan has the
following four phases:

<TABLE>
<CAPTION>
                   PHASE                                            OBJECTIVE
- --------------------------------------------  ------------------------------------------------------
<S>                                           <C>
Phase I-- Business Impact Assessment........  To assess the impact upon Residential Funding business
                                              units if "mission critical" components were suddenly
                                              not available or significantly impaired as a result of
                                              a natural disaster or other type of disruption,
                                              including as a result of Y2K.

Phase II--Strategic Development.............  To develop broad, strategic plans regarding the manner
                                              in which Residential Funding will operate in the
                                              aftermath of a natural disaster or other type of
                                              disruption, including as a result of Y2K.

Phase III--Business Continuity Planning.....  To develop detailed procedures on how Residential
                                              Funding and individual business units will continue to
                                              operate in the aftermath of a natural disaster or
                                              other type of disruption, including as a result of
                                              Y2K.

Phase IV--Validation........................  To test the plans developed in Phases II and III
                                              above.
</TABLE>

     As of March 31, 1999, Residential Funding had substantially completed
Phases I, II and III of its business continuity plan. As of June 30, 1999,
Residential Funding had substantially completed Phase IV of the plan.

RISKS RELATED TO Y2K

     Although Residential Funding's remediation efforts are directed at
eliminating its Y2K exposure, there can be no assurance that these efforts will
fully mitigate the effect of all Y2K problems. If Residential Funding fails to
identify or correct any material Y2K problem, there could be significant
disruptions in its normal business operations. Such disruptions could have a
material adverse effect on Residential Funding's ability to

     o collect, and monitor any subservicer's collection of, payments on the
       mortgage loans

     o distribute those collections to the trustee and

     o provide reports to certificateholders as described in this prospectus
       supplement.

Furthermore, if any subservicer, the trustee or any other business partner or
any of their respective vendors or third party service providers are not
Y2K-ready, the ability to (a) service the mortgage loans in the case of any
subservicer or any of their respective vendors or third party service providers
and (b) make distributions to certificateholders in the case of the trustee or
any of its vendors or third party service providers, may be materially and
adversely affected.

     This section entitled "Year 2000 Considerations" contains forward-looking
statements within the meaning of Section 27A of the Securities Act. All
statements in this section that are not statements of historical fact are
forward-looking statements. Forward-looking statements made in this Y2K
discussion are subject to some risks and uncertainties. Important factors that
could cause results to differ materially from the forward-looking statements
include, among other things, the ability of Residential Funding to successfully
identify components that may pose Y2K problems, the nature and amount of
programming required to fix the affected components, the costs of labor and
consultants related to these efforts, the continued availability of resources,
both personnel and technology, and the ability of business partners that
interface with Residential Funding to successfully address their Y2K issues.

<PAGE>

                  CERTAIN YIELD AND PREPAYMENT CONSIDERATIONS

GENERAL

     The yields to maturity and the aggregate amount of distributions on the
offered certificates will be affected by the rate and timing of principal
payments on the mortgage loans and the amount and timing of mortgagor defaults
resulting in Realized Losses. The yields may be adversely affected by a higher
or lower than anticipated rate of principal payments on the mortgage loans in
the trust. The rate of principal payments on the mortgage loans will in turn be
affected by the amortization schedules of the mortgage loans, the rate and
timing of mortgagor prepayments on the mortgage loans by the mortgagors,
liquidations of defaulted mortgage loans and purchases of mortgage loans due to
breaches of some representations and warranties.

     The timing of changes in the rate of prepayments, liquidations and
purchases of the mortgage loans may, and the timing of Realized Losses will,
significantly affect the yield to an investor, even if the average rate of
principal payments experienced over time is consistent with an investor's
expectation. In addition, the rate of prepayments of the mortgage loans and the
yield to investors on the certificates may be affected by refinancing programs,
which may include general or targeted solicitations, as described under
"Maturity and Prepayment Considerations" in the prospectus. Since the rate and
timing of principal payments on the mortgage loans will depend on future events
and on a variety of factors, as described in this prospectus supplement and in
the prospectus under "Yield Considerations" and "Maturity and Prepayment
Considerations", no assurance can be given as to the rate or the timing of
principal payments on the offered certificates.

     The mortgage loans in most cases may be prepaid by the mortgagors at any
time without payment of any prepayment fee or penalty, although a portion of the
mortgage loans provide for payment of a prepayment charge, which may have a
substantial effect on the rate of prepayment of those mortgage loans. See
"Description of the Mortgage Pool--Mortgage Pool Characteristics."

     Most of the mortgage loans contain due-on-sale clauses. As described under
"Description of the Certificates--Principal Distributions on the Senior
Certificates" and "--Principal Distributions on the Class M Certificates" in
this prospectus supplement, during specified periods all or a disproportionately
large percentage of principal prepayments on the mortgage loans will be
allocated among the Senior Certificates, other than the Lockout Certificates and
the Principal Only Certificates, and during specified periods no principal
prepayments or, relative to the related Class M Percentage, a disproportionately
small portion of principal prepayments on the mortgage loans will be distributed
to the Lockout Certificates and to each class of Class M Certificates. In
addition to the foregoing, if on any distribution date, the loss level
established for the Class M-2 Certificates or Class M-3 Certificates is exceeded
and a class of Class M Certificates having a higher payment priority is then
outstanding, the Class M-2 Certificates or Class M-3 Certificates, as the case
may be, will not receive distributions relating to principal prepayments on that
distribution date. Furthermore, if the Certificate Principal Balances of the
Senior Certificates, other than the Lockout Certificates and the Principal Only
Certificates, have been reduced to zero, the Lockout Certificates may, under
some circumstances, receive all mortgagor prepayments made during the preceding
calendar month to the extent not paid to the Principal Only Certificates.

     Prepayments, liquidations and purchases of the mortgage loans will result
in distributions to holders of the offered certificates of principal amounts
which would otherwise be distributed over the remaining terms of the mortgage
loans. Factors affecting prepayment, including defaults and liquidations, of
mortgage loans include changes in mortgagors' housing needs, job transfers,
unemployment, mortgagors' net equity in the mortgaged properties, changes in the
value of the mortgaged properties, mortgage market interest rates, solicitations
and servicing decisions. In addition, if prevailing mortgage rates fell
significantly below the mortgage rates on the mortgage loans, the rate of
prepayments, including refinancings, would be expected to increase. Conversely,
if prevailing mortgage rates rose significantly above the mortgage rates on the
mortgage loans, the rate of prepayments on the mortgage loans would be expected
to decrease.

     The rate of defaults on the mortgage loans will also affect the rate and
timing of principal payments on the mortgage loans. In general, defaults on
mortgage loans are expected to occur with greater frequency in their early
years. The rate of default on mortgage loans which are refinance or limited
documentation mortgage loans, and on mortgage loans with high LTV ratios, may be
higher than for other types of mortgage loans. Furthermore, the rate and timing
of prepayments, defaults and liquidations on the mortgage loans will be affected
by the general

                                      S-41

<PAGE>

economic condition of the region of the country in which the related mortgaged
properties are located. The risk of delinquencies and loss is greater and
prepayments are less likely in regions where a weak or deteriorating economy
exists, as may be evidenced by, among other factors, increasing unemployment or
falling property values. See "Maturity and Prepayment Considerations" in the
prospectus.

     Because the mortgage rates on the mortgage loans and the pass-through rates
on the offered certificates, other than the Variable Rate Certificates and
Adjustable Rate Certificates, are fixed, these rates will not change in response
to changes in market interest rates. Accordingly, if market interest rates or
market yields for securities similar to such offered certificates were to rise,
the market value of such offered certificates may decline.

     As described under "Description of the Certificates--Allocation of Losses;
Subordination" and "--Advances," amounts otherwise distributable to holders of
one or more classes of the Class M Certificates may be made available to protect
the holders of the Senior Certificates and holders of any Class M Certificates
with a higher payment priority against interruptions in distributions due to
some mortgagor delinquencies, to the extent not covered by Advances. These
delinquencies may affect the yields to investors on those classes of the Class M
Certificates, and, even if subsequently cured, may affect the timing of the
receipt of distributions by the holders of those classes of Class M
Certificates. Furthermore, the Principal Only Certificates will share in the
principal portion of Realized Losses on the mortgage loans only to the extent
that they are incurred with respect to Discount Mortgage Loans and only to the
extent of the related Discount Fraction. Thus, after the Class B Certificates
and the Class M Certificates are retired or in the case of Excess Special Hazard
Losses, Excess Fraud Losses, Excess Bankruptcy Losses and Extraordinary Losses,
the Senior Certificates, other than the Principal Only Certificates, may be
affected to a greater extent by losses on Non-Discount Mortgage Loans than
losses on Discount Mortgage Loans. In addition, a higher than expected rate of
delinquencies or losses will also affect the rate of principal payments on one
or more classes of the Class M Certificates if it delays the scheduled reduction
of the Senior Accelerated Distribution Percentage or affects the allocation of
prepayments among the Class M Certificates and Class B Certificates.

     The periodic increase in interest paid by the mortgagor of a Buydown
Mortgage Loan may increase the risk of default with respect to the related
mortgage loan. See "Mortgage Loan Program--Underwriting Standards" and "Yield
Considerations" in the prospectus.

     The amount of interest otherwise payable to holders of the offered
certificates will be reduced by any interest shortfalls to the extent not
covered by subordination or the master servicer, including Prepayment Interest
Shortfalls and, in the case of each class of the Class M Certificates, the
interest portions of Realized Losses allocated solely to that class of
certificates. These shortfalls will not be offset by a reduction in the
servicing fees payable to the master servicer or otherwise, except as described
in this prospectus supplement with respect to some Prepayment Interest
Shortfalls. See "Yield Considerations" in the Prospectus and "Description of the
Certificates--Interest Distributions" in this prospectus supplement for a
discussion of the effect of principal prepayments on the mortgage loans on the
yield to maturity of the offered certificates and possible shortfalls in the
collection of interest.

     The yield to investors in the offered certificates will be affected by
Prepayment Interest Shortfalls allocable thereto in the month preceding any
distribution date to the extent that those shortfalls exceed the amount offset
by the master servicer. See "Description of the Certificates--Interest
Distributions" in this prospectus supplement.

     In addition, the yield to maturity on each class of the offered
certificates will depend on, among other things, the price paid by the holders
of the offered certificates and the related pass-through rate. The extent to
which the yield to maturity of an offered certificate is sensitive to
prepayments will depend, in part, upon the degree to which it is purchased at a
discount or premium. In general, if a class of offered certificates is purchased
at a premium and principal distributions thereon occur at a rate faster than
assumed at the time of purchase, the investor's actual yield to maturity will be
lower than anticipated at the time of purchase. Conversely, if a class of
offered certificates is purchased at a discount and principal distributions
thereon occur at a rate slower than assumed at the time of purchase, the
investor's actual yield to maturity will be lower than anticipated at the time
of purchase. For additional considerations relating to the yield on the
certificates, see "Yield Considerations" and "Maturity and Prepayment
Considerations" in the prospectus.

     Sequentially Paying Certificates:  The Senior Certificates, other than the
Principal Only Certificates and Variable Strip Certificates, are entitled to
receive distributions in accordance with various priorities for payment of
principal as described in this prospectus supplement. Distributions of principal
on classes having an earlier priority of payment will be affected by the rates
of prepayment of the mortgage loans early in the life of the mortgage pool. The
timing of commencement of principal distributions and the weighted average lives
of certificates with a later priority of payment will be affected by the rates
of prepayment of the mortgage loans both before and after the commencement of
principal distributions on those classes.

     Lockout Certificates:  Investors in the Lockout Certificates should be
aware that because the Lockout Certificates do not receive any distributions of
payments of principal prior to the distribution date occurring in September
2004, unless the Certificate Principal Balances of the Senior Certificates,
other than the Lockout Certificates and Principal Only Certificates, have been
reduced to zero, the weighted average life of the Lockout Certificates will be
longer than would otherwise be the case. The effect on the market value of the
Lockout Certificates of changes in market interest rates or market yields for
similar securities will be greater than for other classes of Senior Certificates
entitled to principal distributions.

     Certificates with Subordination Features:  After the Certificate Principal
Balances of the Class B Certificates have been reduced to zero, the yield to
maturity on the class of Class M Certificates then outstanding with the lowest
payment priority will be extremely sensitive to losses on the mortgage loans and
the timing of those losses because the entire amount of losses that are covered
by Subordination will be allocated to that class of Class M Certificates. See
"--Class M-2 and Class M-3 Certificate Yield Considerations" below. Furthermore,
because principal distributions are paid to some classes of Senior Certificates
and Class M Certificates before other classes, holders of classes having a later
priority of payment bear a greater risk of losses than holders of classes having
earlier priority for distribution of principal.

     Assumed Final Distribution Date:  The assumed final distribution date with
respect to each class of the offered certificates is August 25, 2029, which is
the distribution date immediately following the latest scheduled maturity date
for any mortgage loan. No event of default, change in the priorities for
distribution among the various classes or other provisions under the pooling and
servicing agreement will arise or become applicable solely by reason of the
failure to retire the entire Certificate Principal Balance of any class of
certificates on or before its assumed final distribution date.

     Weighted Average Life:  Weighted average life refers to the average amount
of time that will elapse from the date of issuance of a security to the date of
distribution to the investor of each dollar distributed in reduction of
principal of the security assuming no losses. The weighted average life of the
offered certificates will be influenced by, among other things, the rate at
which principal of the mortgage loans is paid, which may be in the form of
scheduled amortization, prepayments or liquidations.

     Prepayments on mortgage loans are commonly measured relative to a
prepayment standard or model. The model used in this prospectus supplement, the
prepayment speed assumption, represents an assumed rate of prepayment each month
relative to the then outstanding principal balance of a pool of new mortgage
loans. A prepayment assumption of 100% PSA assumes constant prepayment rates of
0.20% per annum of the then outstanding principal balance of the mortgage loans
in the first month of the life of the mortgage loans and an additional 0.20% per
annum in each month thereafter until the 30th month. Beginning in the 30th month
and in each month thereafter during the life of the mortgage loans, 100% PSA
assumes a constant prepayment rate of 6% per annum each month. As used in the
table below, "0% PSA" assumes prepayment rates equal to 0% of PSA--no
prepayments. Correspondingly, "100% PSA" and "200% PSA" assumes prepayment rates
equal to 100% of PSA and 200% of PSA, respectively, and so forth. PSA does not
purport to be a historical description of prepayment experience or a prediction
of the anticipated rate of prepayment of any pool of mortgage loans, including
the mortgage loans.

     The table captioned "Percent of Initial Certificate Principal Balance
Outstanding at the Following Percentages of PSA" has been prepared on the basis
of assumptions as listed in this paragraph regarding the weighted average
characteristics of the Mortgage Loans that are expected to be included in the
trust as described under "Description of the Mortgage Pool" in this prospectus
supplement and their performance. The table

                                      S-43

assumes, among other things, that: (i) as of the date of issuance of the offered
certificates, the mortgage loans have the following characteristics:

     (ii) the scheduled monthly payment for each mortgage loan has been based on
its outstanding balance, mortgage rate and remaining term to maturity, so that
the mortgage loan will amortize in amounts sufficient for its repayment over its
remaining term to maturity; (iii) none of the unaffiliated sellers, the master
servicer or the depositor will repurchase any mortgage loan, as described under
"Mortgage Loan Program--Representations by Sellers" and "Description of the
Certificates--Assignment of the Trust Fund Assets" in the prospectus, and
neither the master servicer nor the depositor exercises any option to purchase
the mortgage loans and thereby cause a termination of the trust; (iv) there are
no delinquencies or Realized Losses on the mortgage loans, and principal
payments on the mortgage loans will be timely received together with
prepayments, if any, at the respective constant percentages of PSA set forth in
the table; (v) there is no Prepayment Interest Shortfall or any other interest
shortfall in any month; (vi) payments on the certificates will be received on
the 25th day of each month, commencing in September 1999; (vii) payments on the
mortgage loans earn no reinvestment return; (viii) there are no additional
ongoing trust expenses payable out of the trust; and (ix) the certificates will
be purchased on August 30, 1999. Clauses (i) through (ix) above are collectively
referred to as the structuring assumptions.

     The actual characteristics and performance of the mortgage loans will
differ from the assumptions used in constructing the table below, which is
hypothetical in nature and is provided only to give a general sense of how the
principal cash flows might behave under varying prepayment scenarios. For
example, it is very unlikely that the mortgage loans will prepay at a constant
level of PSA until maturity or that all of the mortgage loans will prepay at the
same level of PSA. Moreover, the diverse remaining terms to maturity and
mortgage rates of the mortgage loans could produce slower or faster principal
distributions than indicated in the table at the various constant percentages of
PSA specified, even if the weighted average remaining term to maturity and
weighted average mortgage rate of the mortgage loans are as assumed. Any
difference between the assumptions and the actual characteristics and
performance of the mortgage loans, or actual prepayment or loss experience, will
affect the percentages of initial Certificate Principal Balances outstanding
over time and the weighted average lives of the classes of offered certificates.

     In accordance with the foregoing discussion and assumptions, the following
table indicates the weighted average life of each class of offered certificates,
other than the Variable Strip Certificates and Residual Certificates, and sets
forth the percentages of the initial Certificate Principal Balance of each class
of offered certificates that would be outstanding after each of the distribution
dates at the various percentages of PSA shown.

ADJUSTABLE RATE CERTIFICATE YIELD CONSIDERATIONS

     The yield to investors on the Floater Certificates will be sensitive, and
the yield to investors on the Inverse Floater Certificates will be extremely
sensitive, to fluctuations in the level of LIBOR. The pass-through rate on the
Floater Certificates will vary with LIBOR and the pass-through rate on the
Inverse Floater Certificates will vary inversely with and at a multiple of
LIBOR. The pass-through rates on the Adjustable Rate Certificates are subject to
maximum and minimum pass-through rates, and are therefore limited despite
changes in LIBOR in some circumstances. Changes in the level of LIBOR may not
correlate with changes in prevailing mortgage interest rates or changes in other
indices. It is possible that lower prevailing mortgage interest rates, which
might be expected to result in faster prepayments, could occur concurrently with
an increased level of LIBOR. Investors in the Adjustable Rate Certificates
should also fully consider the effect on the yields on those certificates of
changes in the level of LIBOR.

     To illustrate the significance of changes in the level of LIBOR and
prepayments on the yield to maturity on the Adjustable Rate Certificates, the
following tables indicate the approximate pre-tax yields to maturity on a
corporate bond equivalent basis under the different constant percentages of PSA
and varying levels of LIBOR indicated. Because the rate of distribution of
principal on the certificates will be related to the actual amortization,
including prepayments, of the mortgage loans, which will include mortgage loans
that have remaining terms to maturity shorter or longer than assumed and
mortgage rates higher or lower than assumed, the pre-tax yields to maturity on
the Adjustable Rate Certificates are likely to differ from those shown in the
following tables, even if all the mortgage loans prepay at constant percentages
of PSA and the level of LIBOR, the weighted average remaining term to maturity
and the weighted average mortgage rate of the mortgage loans are as assumed. Any
differences between the assumptions and the actual characteristics and
performance of the mortgage loans and of the certificates may result in yields
being different from those shown in the tables. Discrepancies between assumed
and actual characteristics and performance underscore the hypothetical nature of
the tables, which are provided only to give a general sense of the sensitivity
of yields in varying prepayment scenarios and different levels of LIBOR.

     In addition, it is highly unlikely that the mortgage loans will prepay at a
constant level of PSA until maturity, that all of the mortgage loans will prepay
at the same rate, or that the level of LIBOR will remain constant. The timing of
changes in the rate of prepayments may significantly affect the actual yield to
maturity to an investor, even if the average rate of principal prepayments is
consistent with an investor's expectation. In general, the earlier the payment
of principal of the mortgage loans, the greater the effect on an investor's
yield to maturity. As a result, the effect on an investor's yield of principal
prepayments occurring at a rate higher or lower than the rate anticipated by the
investor during the period immediately following the issuance of the
certificates will not be equally offset by a subsequent like reduction or
increase in the rate of principal prepayments.

     The tables below are based on the structuring assumptions, including the
assumptions regarding the characteristics and performance of the mortgage loans
and the certificates, which may differ from their actual characteristics and
performance, and assuming further that:

     o on each LIBOR rate adjustment date, LIBOR will be at the level shown

     o the aggregate purchase prices of the Class A-7 Certificates and
       Class A-8 Certificates are $27,812,767 and $5,683,020, respectively, in
       each case, including accrued interest, and

     o the initial pass-through rates on the Class A-7 Certificates and
       Class A-8 Certificates are described on page S-5 of this prospectus
       supplement.

     There can be no assurance that the mortgage loans will have the assumed
characteristics, will prepay at any of the rates shown in the tables or at any
other particular rate, that the pre-tax yield to maturity on the Adjustable Rate
Certificates will correspond to any of the pre-tax yields to maturity shown in
this prospectus supplement, that the level of LIBOR will correspond to the
levels shown in the table or that the aggregate purchase price of the Adjustable
Rate Certificates will be as assumed. In addition to any other factors an
investor may deem material, each investor must make its own decision as to the
appropriate prepayment assumption to be used and the appropriate levels of LIBOR
to be assumed in deciding whether or not to purchase an Adjustable Rate
Certificate.

     Each pre-tax yield to maturity listed in the preceding tables was
calculated by determining the monthly discount rate which, when applied to the
assumed stream of cash flows to be paid on the Adjustable Rate Certificates,
would cause the discounted present value of the assumed stream of cash flows to
equal the assumed purchase price for those certificates. Accrued interest is
included in the assumed purchase price and is used in computing the corporate
bond equivalent yields shown. These yields do not take into account the
different interest rates at which investors may be able to reinvest funds
received by them as distributions on the Adjustable Rate Certificates, and thus
do not reflect the return on any investment in the Adjustable Rate Certificates
when any reinvestment rates other than the discount rates are considered.

     Notwithstanding the assumed prepayment rates reflected in the preceding
tables, it is highly unlikely that the Mortgage Loans will be prepaid according
to one particular pattern. For this reason, and because the timing of cash flows
is critical to determining yields, the pre-tax yield to maturity on the
Adjustable Rate Certificates is likely to differ from those shown in the tables,
even if all of the mortgage loans prepay at the indicated constant percentages
of PSA over any given time period or over the entire life of the certificates.

     There can be no assurance that the mortgage loans will prepay at any
particular rate or that the yield on the Adjustable Rate Certificates will
conform to the yields described in this prospectus supplement. Moreover, the
various remaining terms to maturity and mortgage rates of the mortgage loans
could produce slower or faster principal distributions than indicated in the
preceding tables at the various constant percentages of PSA specified, even if
the weighted average remaining term to maturity and weighted average mortgage
rate of the mortgage loans are as assumed. Investors are urged to make their
investment decisions based on their determinations as to anticipated rates of
prepayment under a variety of scenarios. Investors in the Adjustable Rate
Certificates should fully consider the risk that a rapid rate of prepayments on
the mortgage loans could result in the failure of those investors to fully
recover their investments.

     For additional considerations relating to the yield on the certificates,
see "Yield Considerations" and "Maturity and Prepayment Considerations" in the
Prospectus.

PRINCIPAL ONLY CERTIFICATE AND VARIABLE STRIP CERTIFICATE YIELD CONSIDERATIONS

     Because the Principal Only Certificates will be purchased at a discount,
the pre-tax yield on the Principal Only Certificates will be adversely affected
by slower than expected payments of principal, including prepayments, defaults,
liquidations and purchases of mortgage loans due to a breach of a representation
and warranty, on the Discount Mortgage Loans.

                                      S-50

<PAGE>

     The yield to maturity on the Variable Strip Certificates will be extremely
sensitive to both the timing of receipt of prepayments and the overall rate of
principal prepayments and defaults on the mortgage loans, which rate may
fluctuate significantly over time. Investors in the Variable Strip Certificates
should fully consider the risk that a rapid rate of prepayments on the mortgage
loans could result in the failure of those investors to fully recover their
investments. Solely with respect to the Variable Strip Certificates, because the
pool strip rates on the Discount Mortgage Loans equal 0.00%, the yield to
investors on the Variable Strip Certificates will not be affected by prepayments
on the Discount Mortgage Loans.

     The following tables indicate the sensitivity of the pre-tax yield to
maturity on the Principal Only Certificates and Variable Strip Certificates to
various constant rates of prepayment on the mortgage loans. The tables are
prepared by projecting the monthly aggregate payments on the Principal Only
Certificates and Variable Strip Certificates and computing the corresponding
pre-tax yields to maturity on a corporate bond equivalent basis, based on the
structuring assumptions, including the assumptions regarding the characteristics
and performance of the mortgage loans, which differ from their actual
characteristics and performance and assuming the aggregate purchase prices,
including accrued interest, if any, set forth below. Any differences between the
assumptions and the actual characteristics and performance of the mortgage loans
and of the Principal Only Certificates and Variable Strip Certificates may
result in yields being different from those shown in the tables. Discrepancies
between assumed and actual characteristics and performance underscore the
hypothetical nature of the tables, which are provided only to give a general
sense of the sensitivity of yields in varying prepayment scenarios.

</TABLE>

     Each pre-tax yield to maturity set forth in the preceding tables was
calculated by determining the monthly discount rate which, when applied to the
assumed stream of cash flows to be paid on the Principal Only Certificates and
Variable Strip Certificates, would cause the discounted present value of the
assumed stream of cash flows to equal the assumed purchase price listed in the
applicable table. Accrued interest, if any, is included in the assumed purchase
price and is used in computing the corporate bond equivalent yields shown. These
yields do not take into account the different interest rates at which investors
may be able to reinvest funds received by them as distributions on the Principal
Only Certificates and Variable Strip Certificates, and thus do not reflect the
return on any investment in the Principal Only Certificates and Variable Strip
Certificates when any reinvestment rates other than the discount rates are
considered.

     Notwithstanding the assumed prepayment rates reflected in the preceding
tables, it is highly unlikely that the mortgage loans will be prepaid according
to one particular pattern. For this reason, and because the timing of cash flows
is critical to determining yields, the pre-tax yields to maturity on the
Principal Only Certificates and Variable Strip Certificates are likely to differ
from those shown in the tables, even if all of the mortgage loans prepay at the
constant percentages of PSA indicated in the tables above over any given time
period or over the entire life of the certificates.

     A lower than anticipated rate of principal prepayments on the Discount
Mortgage Loans will have a material adverse effect on the yield to maturity of
the Principal Only Certificates. The rate and timing of principal prepayments on
the Discount Mortgage Loans may differ from the rate and timing of principal
prepayments on the mortgage pool. In addition, because the Discount Mortgage
Loans have Net Mortgage Rates that are lower than the Net Mortgage Rates of the
Non-Discount Mortgage Loans, and because mortgage loans with lower Net Mortgage
Rates are likely to have lower mortgage rates, the Discount Mortgage Loans are
likely to prepay under most circumstances at a lower rate than the Non-Discount
Mortgage Loans. In addition, holders of the Variable

                                      S-51

<PAGE>

Strip Certificates in most cases have rights to relatively larger portions of
interest payments on mortgage loans with higher mortgage rates; thus, the yield
on the Variable Strip Certificates will be materially adversely affected to a
greater extent than on the other offered certificates if the mortgage loans with
higher mortgage rates prepay faster than the mortgage loans with lower mortgage
rates. Because mortgage loans having higher pool strip rates usually have higher
mortgage rates, these mortgage loans are more likely to be prepaid under most
circumstances than are mortgage loans having lower pool strip rates.

     There can be no assurance that the mortgage loans will prepay at any
particular rate or that the yield on the Principal Only Certificates and
Variable Strip Certificates will conform to the yields described in this
prospectus supplement. Moreover, the various remaining terms to maturity and
mortgage rates of the mortgage loans could produce slower or faster principal
distributions than indicated in the preceding table at the various constant
percentages of PSA specified, even if the weighted average remaining term to
maturity and weighted average mortgage rate of the mortgage loans are as
assumed. Investors are urged to make their investment decisions based on their
determinations as to anticipated rates of prepayment under a variety of
scenarios. Investors in the Variable Strip Certificates should fully consider
the risk that a rapid rate of prepayments on the mortgage loans could result in
the failure of those investors to fully recover their investments.

     For additional considerations relating to the yield on the certificates,
see "Yield Considerations" and "Maturity and Prepayment Considerations" in the
Prospectus.

CLASS M-2 AND CLASS M-3 CERTIFICATE YIELD CONSIDERATIONS

     If the aggregate Certificate Principal Balance of the Class B Certificates
is reduced to zero, the yield to maturity on the Class M-3 Certificates will
become extremely sensitive to losses on the mortgage loans and the timing of
those losses that are covered by subordination, because the entire amount of
those losses will be allocated to the Class M-3 Certificates.

     The aggregate initial Certificate Principal Balance of the Class B
Certificates is equal to approximately 0.70% of the aggregate principal balance
of the mortgage loans as of the cut-off date. If the Certificate Principal
Balances of the Class B Certificates and Class M-3 Certificates have been
reduced to zero, the yield to maturity on the Class M-2 Certificates will become
extremely sensitive to losses on the mortgage loans and the timing of those
losses that are covered by subordination, because the entire amount of those
losses will be allocated to the Class M-2 Certificates. The aggregate initial
Certificate Principal Balance of the Class M-3 Certificates and Class B
Certificates is equal to approximately 1.15% of the aggregate principal balance
of the mortgage loans as of the cut-off date.

     Defaults on mortgage loans may be measured relative to a default standard
or model. The model used in this Prospectus supplement, the standard default
assumption, represents an assumed rate of default each month relative to the
then outstanding performing principal balance of a pool of new mortgage loans. A
default assumption of 100% SDA assumes constant default rates of 0.02% per annum
of the then outstanding principal balance of the mortgage loans in the first
month of the life of the mortgage loans and an additional 0.02% per annum in
each month thereafter until the 30th month. Beginning in the 30th month and in
each month thereafter through the 60th month of the life of the mortgage loans,
100% SDA assumes a constant default rate of 0.60% per annum each month.
Beginning in the 61st month and in each month thereafter through the 120th month
of the life of the mortgage loans, 100% SDA assumes that the constant default
rate declines each month by 0.0095% per annum, and that the constant default
rate remains at 0.03% per annum in each month after the 120th month. For the
purposes of the tables below, it is assumed that there is no delay between the
default and liquidation of the mortgage loans. As used in the table below, "0%
SDA" assumes default rates equal to 0% of SDA--no defaults. Correspondingly,
"200% SDA" assumes default rates equal to 200% of SDA, and so forth. SDA does
not purport to be a historical description of default experience or a prediction
of the anticipated rate of default of any pool of mortgage loans, including the
mortgage loans in this mortgage pool.

     The following tables indicate the sensitivity of the yield to maturity on
the Class M-2 Certificates and Class M-3 Certificates to various rates of
prepayment and varying levels of aggregate Realized Losses by projecting the
monthly aggregate cash flows on the Class M-2 Certificates and Class M-3
Certificates and computing the corresponding pre-tax yield to maturity on a
corporate bond equivalent basis. The tables are based on the structuring
assumptions, except assumption (iv), including the assumptions regarding the
characteristics and

                                      S-52

<PAGE>

performance of the mortgage loans, which differ from their actual
characteristics and performance, and assuming further that:

     o defaults and final liquidations on the mortgage loans occur on the last
       day of each month at the respective SDA percentages set forth in the
       tables

     o each liquidation results in a Realized Loss allocable to principal equal
       to the percentage indicated, the loss severity percentage, multiplied by
       the principal balances of the mortgage loans assumed to be liquidated

     o there are no delinquencies on the mortgage loans, and principal payments
       on the mortgage loans, other than those on mortgage loans assumed to be
       liquidated, will be timely received together with prepayments, if any, at
       the respective constant percentages of PSA set forth in the table

     o there are no Excess Special Hazard Losses, Excess Fraud Losses, Excess
       Bankruptcy Losses or Extraordinary Losses

     o clauses (a)(i), (b)(i) and (b)(ii) in the definition of the Senior
       Accelerated Distribution Percentage are not applicable and

     o the purchase prices of the Class M-2 Certificates and Class M-3
       Certificates will be approximately $2,446,259 and $1,370,289,
       respectively, including accrued interest.

     Investors should also consider the possibility that aggregate losses
incurred may not in fact be materially reduced by higher prepayment speeds
because mortgage loans that would otherwise ultimately default and be liquidated
may be less likely to be prepaid. In addition, investors should be aware that
the following table is based upon the assumption that the Class M-2 Certificates
and Class M-3 Certificates are priced at a discount. Since prepayments will
occur at par, the yield on the Class M-2 Certificates and Class M-3 Certificates
may increase due to those prepayments, even if losses occur. Any differences
between the assumptions and the actual characteristics and performance of the
mortgage loans and of the certificates may result in yields different from those
shown in the tables. Discrepancies between assumed and actual characteristics
and performance underscore the hypothetical nature of the tables, which are
provided only to give a general sense of the sensitivity of yields in varying
Realized Loss and prepayment scenarios.

</TABLE>

     Notwithstanding the assumed percentages of SDA, loss severity and
prepayment reflected in the preceding table, it is highly unlikely that the
mortgage loans will be prepaid or that Realized Losses will be incurred
according to one particular pattern. For this reason, and because the timing of
cash flows is critical to determining yields, the actual pre-tax yields to
maturity on the Class M-2 Certificates and Class M-3 Certificates are likely to
differ from those shown in the tables. There can be no assurance that the
mortgage loans will prepay at any particular rate or that Realized Losses will
be incurred at any particular level or that the yield on the Class M-2
Certificates or Class M-3 Certificates will conform to the yields described in
this prospectus supplement. Moreover, the various remaining terms to maturity
and mortgage rates of the mortgage loans could produce slower or faster
principal distributions than indicated in the preceding tables at the various
constant percentages of PSA specified, even if the weighted average remaining
term to maturity and weighted average mortgage rate of the mortgage loans are as
assumed.

     Investors are urged to make their investment decisions based on their
determinations as to anticipated rates of prepayment and Realized Losses under a
variety of scenarios. Investors in the Class M-2 Certificates and particularly
in the Class M-3 Certificates should fully consider the risk that Realized
Losses on the mortgage loans could result in the failure of those investors to
fully recover their investments. For additional considerations relating to the
yield on the certificates, see "Yield Considerations" and "Maturity and
Prepayment Considerations" in the prospectus.

ADDITIONAL YIELD CONSIDERATIONS APPLICABLE SOLELY TO THE RESIDUAL CERTIFICATES

     The Residual Certificateholders' after-tax rate of return on their Residual
Certificates will reflect their pre-tax rate of return, reduced by the taxes
required to be paid with respect to the Residual Certificates. Holders of
Residual Certificates may have tax liabilities with respect to their Residual
Certificates during the early years of the trust's term that substantially
exceed any distributions payable thereon during any such period. In addition,
holders of Residual Certificates may have tax liabilities with respect to their
Residual Certificates the present value of which substantially exceeds the
present value of distributions payable thereon and of any tax benefits that may
arise with respect thereto. Accordingly, the after-tax rate of return on the
Residual Certificates may be negative or may otherwise be significantly
adversely affected. The timing and amount of taxable income attributable to the
Residual Certificates will depend on, among other things, the timing and amounts
of prepayments and losses experienced with respect to the mortgage pool.

     The Residual Certificateholders should consult their tax advisors as to the
effect of taxes and the receipt of any payments made to those holders in
connection with the purchase of the Residual Certificates on after-tax rates of
return on the Residual Certificates. See "Material Federal Income Tax
Consequences" in this prospectus supplement and "Material Federal Income Tax
Consequences" in the prospectus.

                        POOLING AND SERVICING AGREEMENT

GENERAL

     The certificates will be issued under a pooling and servicing agreement
dated as of August 1, 1999, among the depositor, the master servicer, and The
First National Bank of Chicago, as trustee. Reference is made to the prospectus
for important information in addition to that described herein regarding the
terms and conditions of the pooling and servicing agreement and the offered
certificates. The trustee will appoint Norwest Bank Minnesota, National
Association to serve as custodian in connection with the certificates. The
offered certificates will be transferable and exchangeable at the corporate
trust office of the trustee, which will serve as certificate registrar and
paying agent. The depositor will provide a prospective or actual
certificateholder without charge, on written request, a copy, without exhibits,
of the pooling and servicing agreement. Requests should be addressed to the
President, Residential Funding Mortgage Securities I, Inc., 8400 Normandale Lake
Boulevard, Suite 600, Minneapolis, Minnesota 55437.

     Under the pooling and servicing agreement, transfers of Residual
Certificates are prohibited to any non-United States person. Transfers of the
Residual Certificates are additionally restricted as described in the pooling
and servicing agreement. See "Material Federal Income Tax Consequences" in this
prospectus supplement and "Material ~Federal Income Tax
Consequences--REMICs--Tax on Transfers of REMIC Residual Certificates to Certain
Organizations" and "--Taxation of Owners of REMIC Residual
Certificates--Noneconomic REMIC Residual Certificates" in the prospectus. In
addition to the circumstances described in the prospectus, the depositor may
terminate the trustee for cause under specified circumstances. See "The Pooling
and Servicing Agreement--The Trustee" in the prospectus.

THE MASTER SERVICER

     Residential Funding, an indirect wholly-owned subsidiary of GMAC Mortgage
and an affiliate of the depositor, will act as master servicer for the
certificates under the pooling and servicing agreement. For a general
description of Residential Funding and its activities, see "Residential Funding
Corporation" in the prospectus.

     The following tables set forth information concerning the delinquency
experience, including pending foreclosures, on one- to four-family residential
mortgage loans that generally complied with Residential Funding's published loan
purchase criteria at the time of purchase by Residential Funding and were being
master serviced by Residential Funding at the dates indicated. The tables set
forth information for the total mortgage loan portfolio and for mortgage loans
underwritten under a reduced loan documentation program described under
"Mortgage Loan Program--Underwriting Standards" in the prospectus.

     As used in this prospectus supplement, a loan is considered to be "30 to
59 days" or "30 or more days" delinquent when a payment due on any due date
remains unpaid as of the close of business on the last business day immediately
prior to the next following monthly due date. The determination as to whether a
loan falls into this category is made as of the close of business on the last
business day of each month. Delinquency information presented in this prospectus
supplement as of the cut-off date is determined and prepared as of the close of
business on the last business day immediately prior to the cut-off date.

     The following tables set forth information concerning foreclosed mortgage
loans and loan loss experience of Residential Funding as of the dates indicated,
with respect to the mortgage loans referred to above. For purposes of the
following tables, Average Portfolio Balance for the period indicated is based on
end of month balances divided by the number of months in the period indicated,
the Foreclosed Loans Ratio is equal to the aggregate principal balance of
Foreclosed Loans divided by the Total Loan Portfolio at the end of the indicated
period, and the Gross Loss Ratios and Net Loss Ratios are computed by dividing
the Gross Loss or Net Loss respectively during the period indicated by the
Average Portfolio Balance during that period.

o The tables above relate only to the mortgage loans referred to above.The table
  relates to the mortgage loans referred to above. Some of the information
  reported above may differ from information for the same periods reported by
  the depositor in previous years, because the depositor's methodology for
  determining the total portfolio differed in previous years, but these
  differences in the data are not material.

o For purposes of these tables, Foreclosed Loans includes the principal balance
  of mortgage loans secured by mortgaged properties the title to which has been
  acquired by Residential Funding, by investors or by an insurer following
  foreclosure or delivery of a deed in lieu of foreclosure and which had not
  been liquidated by the end of the period indicated.

o Liquidated Foreclosed Loans is the sum of the principal balances of the
  foreclosed loans liquidated during the period indicated.

o Gross Loss is the sum of the gross losses less net gains (Excess Recoveries)
  on all mortgage loans liquidated during the period indicated. Gross Loss for
  any mortgage loan is equal to the difference between (a) the principal balance
  plus accrued interest plus all liquidation expenses related to that mortgage
  loan and (b) all amounts received in connection with the liquidation of the
  related mortgaged property, excluding amounts received from mortgage pool or
  special hazard insurance or other forms of credit enhancement, as described
  below. Net gains from the liquidation of mortgage loans are identified below.

o Covered Loss, for the period indicated, is equal to the aggregate of all
  proceeds received in connection with liquidated mortgage loans from mortgage
  pool insurance, special hazard insurance (but not including primary mortgage
  insurance, special hazard insurance or other insurance available for specific
  mortgaged properties) or other insurance as well as all proceeds received from
  or losses borne by other credit enhancement, including subordinate
  certificates.

o Net Loss is determined by subtracting Covered Loss from Gross Loss. Net Loss
  indicated here may reflect Excess Recovery. Net Loss includes losses on
  mortgage loan pools which do not have the benefit of credit enhancement.

o Excess Recovery is calculated only with respect to defaulted mortgage loans as
  to which the liquidation of the related mortgaged property resulted in
  recoveries in excess of the principal balance plus accrued interest thereon
  plus all liquidation expenses related to that mortgage loan. Excess Recoveries
  are not applied to reinstate any credit enhancement, and usually are not
  allocated to holders of certificates.

     The loss and delinquency experience of the master servicer, as shown in the
tables above, reflects a stable, consistently managed servicing operation. Loss
and delinquency levels during these periods were consistently within the ranges
anticipated by management. The loss and delinquency levels have declined over
the years shown in the above tables. This decline is attributable primarily to
generally favorable and improving economic conditions over this time period.
There can be no assurance that the experience shown in the above tables will be
indicative of future loss and delinquency experience of the total portfolio, or
of the mortgage loans in the trust.

     There can be no assurance that factors beyond Residential Funding's
control, such as weakening national or local economic conditions, higher
interest rates, higher unemployment rates, a decline in the availability of
refinancing, or downturns in real estate markets, will not result in increased
rates of delinquencies and foreclosure losses in the future. A general
deterioration of the real estate market in regions where the mortgaged
properties are located may result in higher delinquencies, delays in foreclosure
and lower sales prices with higher losses upon liquidation. A general weakening
of the economy may result in decreases in the financial strength of borrowers
and decreases in the value of collateral serving as security for loans, causing
an increase in delinquencies and higher net losses on liquidated loans.

SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES

     The servicing fees for each mortgage loan are payable out of the interest
payments on that mortgage loan. The servicing fees relating to each mortgage
loan will be at least 0.28% per annum and not more than 0.33% per annum of the
outstanding principal balance of that mortgage loan, with a weighted average
servicing fee of approximately 0.3149% per annum. The servicing fees consist of
(a) servicing compensation payable to the master servicer in respect of its
master servicing activities and (b) subservicing and other related compensation
payable to the subservicer, including any payment due to prepayment charges on
the related mortgage loans and such compensation paid to the master servicer as
the direct servicer of a mortgage loan for which there is no subservicer.

     The primary compensation to be paid to the master servicer for its master
servicing activities will be at least 0.03% per annum and not more than 0.08%
per annum of the outstanding principal balance of each mortgage loan, with a
weighted average of approximately 0.0649%. As described in the prospectus, a
subservicer is entitled to servicing compensation in a minimum amount equal to
0.25% per annum of the outstanding principal balance of each mortgage loan
serviced by it. The master servicer is obligated to pay some ongoing expenses
associated with the trust and incurred by the master servicer in connection with
its responsibilities under the pooling and servicing agreement. See "The Pooling
and Servicing Agreement--Servicing and Other Compensation and Payment of
Expenses" in the prospectus for information regarding other possible
compensation to the master servicer and subservicers and for information
regarding expenses payable by the master servicer.

VOTING RIGHTS

     There are actions specified in the prospectus that may be taken by holders
of certificates evidencing a specified percentage of all undivided interests in
the trust and may be taken by holders of certificates entitled in the aggregate
to that percentage of the voting rights. 98% of all voting rights will be
allocated among all holders of the Certificates, other than the Interest Only
Certificates and Residual Certificates, in proportion to their then outstanding
Certificate Principal Balances, 1.0% of all voting rights will be allocated
among the holders of the Variable Strip Certificates and 1.0% of all voting
rights will be allocated among the holders of the Class R Certificates, in
proportion to the percentage interests evidenced by their respective
certificates. The pooling and servicing agreement may be amended without the
consent of the holders of the Residual Certificates in specified circumstances.

TERMINATION

     The circumstances under which the obligations created by the pooling and
servicing agreement will terminate relating to the offered certificates are
described in "The Pooling and Servicing Agreement--Termination; Retirement of
Certificates" in the Prospectus. The master servicer or the depositor will have
the option, on any distribution date on which the aggregate Stated Principal
Balance of the mortgage loans is less than 10% of the aggregate principal
balance of the mortgage loans as of the cut-off date, either to purchase all
remaining mortgage loans and other assets in the trust, thereby effecting early
retirement of the offered certificates or to purchase, in whole but not in part,
the certificates. Any such purchase of mortgage loans and other assets of the
trust shall be made at a price equal to the sum of (a) 100% of the unpaid
principal balance of each mortgage loan or the fair market value of the related
underlying mortgaged properties with respect to defaulted mortgage loans as to
which title to such mortgaged properties has been acquired if such fair market
value is less than such unpaid principal balance, net of any unreimbursed
Advance attributable to principal, as of the date of repurchase plus
(b) accrued interest thereon at the Net Mortgage Rate to, but not including, the
first day of the month in which the repurchase price is distributed.

     Distributions on the certificates relating to any optional termination will
be paid, first, to the Senior Certificates, second, to the Class M Certificates
in the order of their payment priority and, third, to the Class B Certificates.
The proceeds of any such distribution may not be sufficient to distribute the
full amount to each class of certificates if the purchase price is based in part
on the fair market value of the underlying mortgaged property and the fair
market value is less than 100% of the unpaid principal balance of the related
mortgage loan. Any such purchase of the certificates will be made at a price
equal to 100% of their Certificate Principal Balance plus, except with respect
to the Principal Only Certificates, the sum of interest thereon, or with respect
to the

                                      S-60

<PAGE>

Variable Strip Certificates, on their Notional Amount, for the immediately
preceding Interest Accrual Period at the then-applicable pass-through rate and
any previously unpaid Accrued Certificate Interest. Upon the purchase of such
certificates or at any time thereafter, at the option of the master servicer or
the depositor, the mortgage loans may be sold, thereby effecting a retirement of
the certificates and the termination of the trust, or the certificates so
purchased may be held or resold by the master servicer or the depositor.

     Upon presentation and surrender of the offered certificates in connection
with the termination of the trust or a purchase of certificates under the
circumstances described in the two preceding paragraphs, the holders of the
offered certificates will receive an amount equal to the Certificate Principal
Balance of that class plus interest thereon for the immediately preceding
Interest Accrual Period at the then-applicable pass-through rate, or, with
respect to the Variable Strip Certificates, interest for the immediately
preceding Interest Accrual Period on their Notional Amount, plus any previously
unpaid Accrued Certificate Interest. However, distributions to the holders of
the most subordinate class of certificates outstanding will be reduced, as
described in the preceding paragraph, in the case of the termination of the
trust resulting from a purchase of all the assets of the trust.

                    MATERIAL FEDERAL INCOME TAX CONSEQUENCES

     Thacher Proffitt & Wood, counsel to the depositor, has filed with the
depositor's registration statement an opinion to the effect that, assuming
compliance with all provisions of the pooling and servicing agreement, for
federal income tax purposes, the trust will qualify as a REMIC under the
Internal Revenue Code.

     For federal income tax purposes:

     o the Class R Certificates will constitute the sole class of "residual
       interests" in the REMIC and

     o each class of Senior Certificates, other than the Residual Certificates,
       the Class M Certificates and the Class B Certificates will represent
       ownership of "regular interests" in the REMIC and will generally be
       treated as debt instruments of the REMIC.

     See "Material Federal Income Tax Consequences--REMICs" in the prospectus.

     For federal income tax purposes, the Class A-1, Class A-3 and Class A-7
Certificates will not and all other Classes of Offered Certificates will be
treated as having been issued with original issue discount. The prepayment
assumption that will be used in determining the rate of accrual of original
issue discount, market discount and premium, if any, for federal income tax
purposes will be based on the assumption that, subsequent to the date of any
determination the mortgage loans will prepay at a rate equal to 200% PSA. No
representation is made that the mortgage loans will prepay at that rate or at
any other rate. See "Material Federal Income Tax Consequences--General" and
"--REMICs--Taxation of Owners of REMIC Regular Certificates--Original Issue
Discount" in the prospectus.

     The Internal Revenue Service has issued original issue discount regulations
under sections 1271 to 1275 of the Internal Revenue Code that address the
treatment of debt instruments issued with original issue discount. The OID
regulations suggest that original issue discount with respect to securities
similar to the Variable Strip Certificates that represent multiple
uncertificated REMIC regular interests, in which ownership interests will be
issued simultaneously to the same buyer, should be computed on an aggregate
method. In the absence of further guidance from the IRS, original issue discount
with respect to the uncertificated regular interests represented by the Variable
Strip Certificates will be reported to the IRS and the certificateholders on an
aggregate method based on a single overall constant yield and the prepayment
assumption stated above, treating all uncertificated regular interests as a
single debt instrument as described in the OID regulations.

     If the method for computing original issue discount described in the
prospectus results in a negative amount for any period with respect to a
certificateholder, the amount of original issue discount allocable to that
period would be zero and the certificateholder will be permitted to offset that
negative amount only against future original issue discount, if any,
attributable to those certificates.

     In some circumstances the OID regulations permit the holder of a debt
instrument to recognize original issue discount under a method that differs from
that used by the issuer. Accordingly, it is possible that the holder of a
certificate may be able to select a method for recognizing original issue
discount that differs from that used by the master servicer in preparing reports
to the certificateholders and the IRS.

                                      S-61

<PAGE>

     Some of the classes of offered certificates may be treated for federal
income tax purposes as having been issued at a premium. Whether any holder of
one of those classes of certificates will be treated as holding a certificate
with amortizable bond premium will depend on the certificateholder's purchase
price and the distributions remaining to be made on the certificate at the time
of its acquisition by the certificateholder. Holders of those classes of
certificates should consult their tax advisors regarding the possibility of
making an election to amortize such premium. See "Material Federal Income Tax
Consequences--REMICs--Taxation of Owners of REMIC Regular Certificates" and
"--Premium" in the prospectus.

     The offered certificates will be treated as assets described in Section
7701(a)(19)(C) of the Internal Revenue Code and "real estate assets" under
Section 856(c)(4)(A) of the Internal Revenue Code generally in the same
proportion that the assets of the trust would be so treated. In addition,
interest on the offered certificates will be treated as "interest on obligations
secured by mortgages on real property" under Section 856(c)(3)(B) of the
Internal Revenue Code generally to the extent that the offered certificates are
treated as "real estate assets" under Section 856(c)(4)(A) of the Internal
Revenue Code. Moreover, the offered certificates, other than the Residual
Certificates, will be "qualified mortgages" within the meaning of Section
860G(a)(3) of the Internal Revenue Code if transferred to another REMIC on its
startup day in exchange for a regular or residual interest therein. However,
prospective investors in offered certificates that will be generally treated as
assets described in Section 860G(a)(3) of the Internal Revenue Code should note
that, notwithstanding that treatment, any repurchase of a certificate pursuant
to the right of the master servicer or the depositor to repurchase the offered
certificates may adversely affect any REMIC that holds the offered certificates
if the repurchase is made under circumstances giving rise to a Prohibited
Transaction Tax. See "The Pooling and Servicing Agreement--Termination" in this
prospectus supplement and "Material Federal Income Tax Consequences--REMICs--
Characterization of Investments in REMIC Certificates" in the prospectus.

     For further information regarding federal income tax consequences of
investing in the offered certificates, see "Material Federal Income Tax
Consequences--REMICs" in the prospectus.

SPECIAL TAX CONSIDERATIONS APPLICABLE TO RESIDUAL CERTIFICATES

     The IRS has issued REMIC regulations under the provisions of the Internal
Revenue Code that significantly affect holders of Residual Certificates. The
REMIC regulations impose restrictions on the transfer or acquisition of some
residual interests, including the Residual Certificates. The pooling and
servicing agreement includes other provisions regarding the transfer of Residual
Certificates, including:

     o the requirement that any transferee of a Residual Certificate provide an
       affidavit representing that the transferee:

      o is not a disqualified organization

      o is not acquiring the Residual Certificate on behalf of a disqualified
        Organization and

      o will maintain that status and will obtain a similar affidavit from any
        person to whom the transferee shall subsequently transfer a Residual
        Certificate

     o a provision that any transfer of a Residual Certificate to a disqualified
       organization shall be null and void and

     o a grant to the master servicer of the right, without notice to the holder
       or any prior holder, to sell to a purchaser of its choice any Residual
       Certificate that shall become owned by a disqualified organization
       despite the first two provisions above.

In addition, under the pooling and servicing agreement, the Residual
Certificates may not be transferred to non-United States persons.

     The REMIC regulations also provide that a transfer to a United States
person of "noneconomic" residual interests will be disregarded for all federal
income tax purposes, and that the purported transferor of "noneconomic" residual
interests will continue to remain liable for any taxes due with respect to the
income on the residual interests, unless "no significant purpose of the transfer
was to impede the assessment or collection of tax." Based on the REMIC
regulations, the Residual Certificates may constitute noneconomic residual
interests

                                      S-62

<PAGE>

during some or all of their terms for purposes of the REMIC regulations and,
accordingly, unless no significant purpose of a transfer is to impede the
assessment or collection of tax, transfers of the Residual Certificates may be
disregarded and purported transferors may remain liable for any taxes due
relating to the income on the Residual Certificates. All transfers of the
Residual Certificates will be restricted in accordance with the terms of the
pooling and servicing agreement that are intended to reduce the possibility of
any transfer of a Residual Certificate being disregarded to the extent that the
Residual Certificates constitute noneconomic residual interests. See "Material
Federal Income Tax Consequences--REMICs--Taxation of Owners of REMIC Residual
Certificates--Noneconomic REMIC Residual Certificates" in the prospectus.

     The Residual Certificateholders may be required to report an amount of
taxable income with respect to the earlier accrual periods of the term of the
REMIC that significantly exceeds the amount of cash distributions received by
the Residual Certificateholders from the REMIC with respect to those periods.
Furthermore, the tax on that income may exceed the cash distributions with
respect to those periods. Consequently, Residual Certificateholders should have
other sources of funds sufficient to pay any federal income taxes due in the
earlier years of the REMIC's term as a result of their ownership of the Residual
Certificates. In addition, the required inclusion of this amount of taxable
income during the REMIC's earlier accrual periods and the deferral of
corresponding tax losses or deductions until later accrual periods or until the
ultimate sale or disposition of a Residual Certificate, or possibly later under
the "wash sale" rules of Section 1091 of the Internal Revenue Code may cause the
Residual Certificateholders' after-tax rate of return to be zero or negative
even if the Residual Certificateholders' pre-tax rate of return is positive.
That is, on a present value basis, the Residual Certificateholders' resulting
tax liabilities could substantially exceed the sum of any tax benefits and the
amount of any cash distributions on the Residual Certificates over their life.

     An individual, trust or estate that holds, whether directly or indirectly
through pass-through entities, a Residual Certificate, may have significant
additional gross income with respect to, but may be limited on the deductibility
of, servicing and trustee's fees and other administrative expenses properly
allocable to the REMIC in computing the certificateholder's regular tax
liability and will not be able to deduct those fees or expenses to any extent in
computing the certificateholder's alternative minimum tax liability. See
"Material Federal Income Tax Consequences--REMICs--Taxation of Owners of REMIC
Residual Certificates--Possible Pass-Through of Miscellaneous Itemized
Deductions" in the prospectus.

     Residential Funding will be designated as the "tax matters person" with
respect to the REMIC as defined in the REMIC Provisions, as defined in the
prospectus, and in connection therewith will be required to hold not less than
0.01% of the Class R Certificates.

     Purchasers of the Residual Certificates are strongly advised to consult
their tax advisors as to the economic and tax consequences of investment in the
Residual Certificates.

     For further information regarding the federal income tax consequences of
investing in the Residual Certificates, see "Certain Yield and Prepayment
Considerations--Additional Yield Considerations Applicable Solely to the
Residual Certificates"in this prospectus supplement and "Material Federal Income
Tax Consequences--REMICs--Taxation of Owners of REMIC Residual Certificates" in
the prospectus.

                             METHOD OF DISTRIBUTION

     In accordance with the terms and conditions of an underwriting agreement,
dated August 24, 1999, PaineWebber Incorporated will serve as an underwriter and
has agreed to purchase and the depositor has agreed to sell the Senior
Certificates other than the Class A-P Certificates and Class A-V Certificates,
except that a de minimis portion of the Residual Certificates will be retained
by Residential Funding, and that portion is not offered hereby, and the
Class M-2 Certificates and Class M-3 Certificates. The certificates being sold
to PaineWebber Incorporated are referred to as the PaineWebber underwritten
certificates. It is expected that delivery of the PaineWebber underwritten
certificates, other than the Residual Certificates, will be made only in
book-entry form through the Same Day Funds Settlement System of DTC, and that
the delivery of the Residual Certificates will be made at the offices of
PaineWebber Incorporated, New York, New York, on or about August 30, 1999
against payment therefor in immediately available funds.

                                      S-63

<PAGE>

     In accordance with the terms and conditions of a Class M-1 underwriting
agreement, dated August 24, 1999, Residential Funding Securities Corporation
will serve as Class M-1 underwriter and has agreed to purchase on a best efforts
basis and the depositor has agreed to sell the Class M-1 Certificates. The
certificates being sold to the Class M-1 underwriter are referred to as the
Class M-1 underwritten certificates. It is expected that delivery of the
Class M-1 underwritten certificates will be made only in book-entry form through
the Same Day Funds Settlement System of DTC against payment therefor in
immediately available funds. The termination date of the offering of the
Class M-1 underwritten certificates is the earlier to occur of August 24, 2000
or the date on which all of the Class M-1 certificates have been sold. Proceeds
of the Class M-1 underwritten certificates will not be placed in escrow, trust
or similar arrangement.

     The PaineWebber underwriting agreement and the Class M-1 underwriting
agreement are collectively referred to in this prospectus supplement as the
underwriting agreements and PaineWebber Incorporated and the Class M-1
underwriter are referred to in this prospectus supplement together as the
underwriters. The PaineWebber underwritten certificates and the Class M-1
underwritten certificates are collectively referred to in this prospectus
supplement as the underwritten certificates.

     In connection with the underwritten certificates, the related underwriter
has agreed, in accordance with the terms and conditions of the related
underwriting agreement, to purchase all of its respective underwritten
certificates if any of those underwritten certificates are purchased thereby.

     The underwriting agreements provide that the obligations of the
underwriters to pay for and accept delivery of their respective underwritten
certificates are subject to, among other things, the receipt of legal opinions
and to the conditions, among others, that no stop order suspending the
effectiveness of the depositor's registration statement shall be in effect, and
that no proceedings for that purpose shall be pending before or threatened by
the Securities and Exchange Commission.

     The distribution of the underwritten certificates by the respective
underwriters may be effected from time to time in one or more negotiated
transactions, or otherwise, at varying prices to be determined at the time of
sale. Proceeds to the depositor from the sale of the PaineWebber underwritten
certificates, before deducting expenses payable by the depositor, will be
approximately 97.83% of the aggregate Certificate Principal Balance of the
PaineWebber underwritten certificates plus accrued interest thereon from the
cut-off date. The proceeds to the depositor from any sale of the Class M-1
underwritten certificates will be equal to the purchase price paid by the
purchaser of these underwritten certificates, net of any expenses payable by the
depositor and any compensation payable to Residential Funding Securities
Corporation and any dealer.

     The underwriters may effect these transactions by selling their respective
underwritten certificates to or through dealers, and those dealers may receive
compensation in the form of underwriting discounts, concessions or commissions
from the underwriters for whom they act as agent. In connection with the sale of
the underwritten certificates, the underwriters may be deemed to have received
compensation from the depositor in the form of underwriting compensation. The
underwriters and any dealers that participate with the underwriters in the
distribution of the related underwritten certificates may be deemed to be
underwriters and any profit on the resale of the underwritten certificates
positioned by them may be deemed to be underwriting discounts and commissions
under the Securities Act.

     The underwriting agreements provide that the depositor will indemnify the
related underwriter, and that under limited circumstances the related
underwriter will indemnify the depositor, against some liabilities under the
Securities Act, or contribute to payments required to be made in respect
thereof.

     The Class A-P Certificates and Class A-V Certificates may be offered by the
depositor from time to time directly or through an underwriter or agent in one
or more negotiated transactions, or otherwise, at varying prices to be
determined at the time of sale. However, there is currently no underwriting
arrangement in effect for these certificates. Proceeds to the depositor from any
sale of the Class A-P Certificates or the Class A-V Certificates will equal the
purchase price paid by their purchaser, net of any expenses payable by the
depositor and any compensation payable to any underwriter or agent.

     There is currently no secondary market for the offered certificates. Each
underwriter intends to make a secondary market in its respective underwritten
certificates but is not obligated to do so. There can be no

                                      S-64

<PAGE>

assurance that a secondary market for the offered certificates will develop or,
if it does develop, that it will continue. The offered certificates will not be
listed on any securities exchange.

     The primary source of information available to investors concerning the
offered certificates will be the monthly statements discussed in the prospectus
under "Description of the Certificates--Reports to Certificateholders," which
will include information as to the outstanding principal balance of the offered
certificates. There can be no assurance that any additional information
regarding the offered certificates will be available through any other source.
In addition, the depositor is not aware of any source through which price
information about the offered certificates will be available on an ongoing
basis. The limited nature of this information regarding the offered certificates
may adversely affect the liquidity of the offered certificates, even if a
secondary market for the offered certificates becomes available.

                                 LEGAL OPINIONS

     Certain legal matters relating to the certificates will be passed upon for
the depositor and the Class M-1 underwriter by Thacher Proffitt & Wood, New
York, New York and for PaineWebber Incorporated by Brown & Wood LLP, New York,
New York.

                                    RATINGS

     It is a condition of the issuance of the Senior Certificates, other than
the Inverse Floater, Principal Only and Variable Strip Certificates, that they
be rated "AAA" by Standard & Poor's, a division of The McGraw-Hill Companies,
Inc., or Standard & Poor's, and Fitch IBCA, Inc., or Fitch IBCA. It is a
condition to the issuance of the Inverse Floater, Principal Only and the
Variable Strip Certificates that they be rated "AAAr" by Standard & Poor's and
"AAA" by Fitch IBCA. It is a condition of the issuance of the Class M-1,
Class M-2 and Class M-3 Certificates that they be rated not lower than "AA," "A"
and "BBB," respectively, by Fitch IBCA.

     Standard & Poor's ratings on mortgage pass-through certificates address the
likelihood of the receipt by certificateholders of payments required under the
pooling and servicing agreement. Standard & Poor's ratings take into
consideration the credit quality of the mortgage pool, structural and legal
aspects associated with the certificates, and the extent to which the payment
stream in the mortgage pool is adequate to make payments required under the
certificates. Standard & Poor's rating on the certificates does not, however,
constitute a statement regarding frequency of prepayments on the mortgages. See
"Certain Yield and Prepayment Considerations" in this prospectus supplement. The
"r" of the "AAAr" rating of the Inverse Floater, Principal Only and Variable
Strip Certificates by Standard & Poor's is attached to highlight derivative,
hybrid, and certain other obligations that Standard & Poor's believes may
experience high volatility or high variability in expected returns due to
non-credit risks. Examples of such obligations are:

     o securities whose principal or interest return is indexed to equities,
       commodities, or currencies;

     o certain swaps and options; and

     o interest only and principal only mortgage securities.

     The absence of an "r" symbol should not be taken as an indication that an
obligation will exhibit no volatility or variability in total return.

     The ratings assigned by Fitch IBCA to mortgage pass-through certificates
address the likelihood of the receipt by certificateholders of all distributions
to which they are entitled under the transaction structure. Fitch IBCA's ratings
reflect its analysis of the riskiness of the underlying mortgage loans and the
structure of the transaction as described in the operative documents. Fitch
IBCA's ratings do not address the effect on the certificates' yield attributable
to prepayments or recoveries on the underlying mortgage loans. Further, the
rating on the Variable Strip Certificates does not address whether investors
therein will recoup their initial investments. The rating on the Principal Only
Certificates only addresses the return of its Certificate Principal Balance. The
rating on the Residual Certificates only addresses the return of its Certificate
Principal Balance and interest on the Residual Certificates at the related
pass-through rate.

                                      S-65

<PAGE>

     The depositor has not requested a rating on the Senior Certificates by any
rating agency other than Standard & Poor's and Fitch IBCA or on the Class M
Certificates by any rating agency other than Fitch IBCA. However, there can be
no assurance as to whether any other rating agency will rate the Senior
Certificates or Class M Certificates, or, if it does, what rating would be
assigned by any other rating agency. A rating on the Certificates by another
rating agency, if assigned at all, may be lower than the ratings assigned to the
Senior Certificates by Standard & Poor's and Fitch IBCA, and the Class M
Certificates by Fitch IBCA.

     A security rating is not a recommendation to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning rating
organization. Each security rating should be evaluated independently of any
other security rating. The ratings of the Variable Strip Certificates do not
address the possibility that the holders of those certificates may fail to fully
recover their initial investments. In the event that the ratings initially
assigned to the offered certificates are subsequently lowered for any reason, no
person or entity is obligated to provide any additional support or credit
enhancement with respect to the offered certificates.

                                LEGAL INVESTMENT

     The Senior Certificates and Class M-1 Certificates will constitute
"mortgage related securities" for purposes of SMMEA so long as they are rated in
at least the second highest rating category by one of the rating agencies, and,
as such, are legal investments for some entities to the extent provided in
SMMEA. SMMEA provides, however, that states could override its provisions on
legal investment and restrict or condition investment in mortgage related
securities by taking statutory action on or prior to October 3, 1991. Some
states have enacted legislation which overrides the preemption provisions of
SMMEA. The Class M-2 Certificates and Class M-3 Certificates will not constitute
"mortgage related securities" for purposes of SMMEA.

     One or more classes of the offered certificates may be viewed as "complex
securities" under TB13a, which applies to thrift institutions regulated by the
OTS.

     The depositor makes no representations as to the proper characterization of
any class of the offered certificates for legal investment or other purposes, or
as to the ability of particular investors to purchase any class of the offered
certificates under applicable legal investment restrictions. These uncertainties
may adversely affect the liquidity of any class of offered certificates.
Accordingly, all institutions whose investment activities are subject to legal
investment laws and regulations, regulatory capital requirements or review by
regulatory authorities should consult with their legal advisors in determining
whether and to what extent any class of the offered certificates constitutes a
legal investment or is subject to investment, capital or other restrictions.

     See "Legal Investment Matters" in the prospectus.

                              ERISA CONSIDERATIONS

     A fiduciary of any ERISA plan, any insurance company, whether through its
general or separate accounts, or any other person investing ERISA plan assets of
any ERISA plan, as defined under "ERISA Considerations--Plan Asset Regulations"
in the prospectus, should carefully review with its legal advisors whether the
purchase or holding of offered certificates could give rise to a transaction
prohibited or not otherwise permissible under ERISA or Section 4975 of the
Internal Revenue Code. The purchase or holding of the offered certificates,
other than the Class M Certificates or Residual Certificates, by or on behalf
of, or with ERISA plan assets of, an ERISA plan may qualify for exemptive relief
under the exemption, as described under "ERISA Considerations--Prohibited
Transaction Exemptions" in the prospectus. However, the exemption contains a
number of conditions which must be met for the exemption to apply, including the
requirement that the investing ERISA plan must be an "accredited investor" as
defined in Rule 501(a)(1) of Regulation D of the Securities and Exchange
Commission under the Securities Act.

     Insurance companies contemplating the investment of general account assets
in the offered certificates should consult with their legal advisors with
respect to the applicability of Section 401(c) of ERISA, as described under
"ERISA Considerations--Insurance Company General Accounts" in the prospectus.
The DOL issued proposed regulations under Section 401(c) on December 22, 1997,
but the required final regulations have not been issued as of the date of this
prospectus supplement.

                                      S-66

<PAGE>

     Because the exemptive relief afforded by the exemption or any similar
exemption that may be available will not likely apply to the purchase, sale or
holding of the Class M Certificates, no Class M Certificate or any interest
therein may be acquired or held by any ERISA plan, any trustee or other person
acting on behalf of any ERISA plan, or any other person using ERISA plan assets
to effect such acquisition or holding--a plan investor--unless:

     o the acquirer or holder is an insurance company

     o the source of funds used to acquire or hold the certificate or interest
       therein is an "insurance company general account", as defined in U.S.
       Department of Labor Prohibited Transaction Class Exemption 95-60 and

     o the conditions in Sections I and III of PTCE 95-60 have been satisfied.

     Each beneficial owner of a Class M Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
that certificate or interest therein, that either (i) it is not a plan investor
or (ii) (1) it is an insurance company, (2) the source of funds used to acquire
or hold the certificate or interest therein is an "insurance company general
account", as such term is defined in PTCE 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

     If any Class M Certificate or any interest therein is acquired or held in
violation of the provisions of the preceding paragraph, the next preceding
permitted beneficial owner will be treated as the beneficial owner of that
Class M Certificate, retroactive to the date of transfer to the purported
beneficial owner. Any purported beneficial owner whose acquisition or holding of
any such certificate or interest therein was effected in violation of the
provisions of the preceding paragraph shall indemnify and hold harmless the
depositor, the trustee, the master servicer, any subservicer, and the trust from
and against any and all liabilities, claims, costs or expenses incurred by those
parties as a result of that acquisition or holding.

     Investors in the Class M Certificates are urged to obtain from a transferee
of those certificates a certification of the transferee's eligibility to
purchase the certificates in the form of the representation letter attached as
Annex I to this prospectus supplement.

     Because the exemptive relief afforded by the exemption or any similar
exemption that might be available also will not likely apply to the purchase,
sale or holding of the Residual Certificates, transfers of those certificates to
any plan investor will not be registered by the trustee unless the transferee
provides the depositor, the trustee and the master servicer with an opinion of
counsel satisfactory to those entities, which opinion will not be at the expense
of those entities, that the purchase of those certificates by or on behalf of
the plan investor:

     o is permissible under applicable law

     o will not constitute or result in a non-exempt prohibited transaction
       under ERISA or Section 4975 of the Internal Revenue Code and

     o will not subject the depositor, the trustee or the master servicer to any
       obligation in addition to those undertaken in the pooling and servicing
       agreement.

     Any fiduciary or other investor of ERISA plan assets that proposes to
acquire or hold the offered certificates on behalf of or with ERISA plan assets
of any ERISA plan should consult with its counsel with respect to: (i) whether
the specific and general conditions and the other requirements in the exemption
would be satisfied, or whether any other prohibited transaction exemption would
apply, and (ii) the potential applicability of the general fiduciary
responsibility provisions of ERISA and the prohibited transaction provisions of
ERISA and Section 4975 of the Internal Revenue Code to the proposed investment.
See "ERISA Considerations" in the prospectus.

     The sale of any of the offered certificates to an ERISA plan is in no
respect a representation by the depositor or the related underwriter that such
an investment meets all relevant legal requirements relating to investments by
ERISA plans generally or any particular ERISA plan, or that such an investment
is appropriate for ERISA plans generally or any particular ERISA plan.

Ladies and Gentlemen:

     [                                ] (the "Purchaser") intends to purchase
from [                                ] (the "Seller") $[               ]
initial Certificate Principal Balance of the above-referenced certificates,
issued under the pooling and servicing agreement, dated as of August 1, 1999,
among Residential Funding Mortgage Securities I, Inc., as seller, Residential
Funding Corporation, as master servicer and The First National Bank of Chicago,
as trustee. All terms used in this ERISA Representation Letter and not otherwise
defined shall have the meanings set forth in the pooling and servicing
agreement.

     The Purchaser hereby certifies, represents and warrants to, and covenants
with the Seller, the trustee and the master servicer that, either:

          (a) The Purchaser is not an ERISA plan, or any other person, including
     an investment manager, a named fiduciary or a trustee of any Plan, acting,
     directly or indirectly, on behalf of or purchasing any certificate with
     "plan assets" of any ERISA plan within the meaning of the DOL regulation at
     29 C.F.R. Section 2510.3-101; or

          (b) The Purchaser is an insurance company, the source of funds to be
     used by which to purchase the certificates is an "insurance company general
     account", as the term is defined in DOL Prohibited Transaction Class
     Exemption 95-60, and the conditions in Sections I and III of PTCE 95-60
     have been satisfied.

     In addition, the Purchaser hereby certifies, represents and warrants to,
and covenants with, the Seller, the trustee and the master servicer that the
Purchaser will not transfer the certificates to any ERISA plan or person unless
that ERISA plan or person meets the requirements in either (a) or (b) above.

                                          Very truly yours,

                                  INTRODUCTION

     The  mortgage  pass-through  certificates  offered may be sold from time to
time in series.  Each series of certificates will represent in the aggregate the
entire  beneficial  ownership  interest,  excluding  any  interest  retained  by
Residential  Funding  Mortgage  Securities I, Inc., the depositor,  or any other
entity  specified in the related  prospectus  supplement,  in a trust consisting
primarily  of a  segregated  pool  of  one- to  four-family,  residential  first
mortgage  loans,  acquired  by the  depositor  from  one or more  affiliated  or
unaffiliated  institutions.  Each series of certificates  will be issued under a
pooling and servicing agreement among the depositor,  the trustee and the master
servicer specified in the related prospectus supplement.

                                   THE TRUSTS

GENERAL

     The mortgage loans and other assets described in this prospectus under 'The
Trusts -- The Mortgage Loans' and in the related  prospectus  supplement will be
held  in a trust  for the  benefit  of the  holders  of the  related  series  of
certificates  and the  Excess  Spread,  if any,  under a pooling  and  servicing
agreement as described in this section and in the related prospectus supplement.
As specified in the related prospectus  supplement,  each series of certificates
will represent in the aggregate the entire beneficial  ownership interest in the
mortgage pool consisting primarily of conventional mortgage loans, excluding any
interest  retained by the depositor or any other entity specified in the related
prospectus supplement, evidenced by promissory notes, the mortgage notes secured
by first mortgages or first deeds of trust or other similar security instruments
creating a first lien on one-to four-family residential properties, or interests
in the mortgage loans which may include mortgage securities evidencing interests
in mortgage loans.

     As specified in the related prospectus supplement, the mortgaged properties
will  consist  primarily  of  owner-occupied  attached  or  detached  one-family
dwelling units, two- to four-family  dwelling units,  condominiums,  townhouses,
row  houses,   individual   units  in  planned-unit   developments  and  modular
pre-cut/panelized  housing,  and the fee,  leasehold  or other  interests in the
underlying real property. The mortgaged properties may include vacation,  second
and non-owner-occupied  homes. If specified in the related prospectus supplement
relating to a series of  certificates,  a mortgage pool may contain  Cooperative
Loans evidenced by Cooperative  Notes. In addition,  if specified in the related
prospectus supplement relating to a series of certificates,  a mortgage pool may
contain  Additional  Collateral  Loans or Pledged Asset  Mortgage Loans that are
secured, in addition to the related mortgaged property, by Additional Collateral
or Pledged Assets.

     As used herein,  unless the context  indicates  otherwise,  mortgage  loans
includes  Cooperative  Loans,  Additional  Collateral  Loans and  Pledged  Asset
Mortgage Loans,  mortgaged properties includes shares in the related Cooperative
and the related proprietary leases or occupancy  agreements securing Cooperative
Notes,  mortgage  notes  includes  Cooperative  Notes and  mortgages  includes a
security agreement with respect to a Cooperative Note.

     The  prospectus  supplement  with  respect to a series  will  describe  the
specific  manner in which  certificates of that series issued under a particular
pooling and servicing  agreement will evidence  specified  beneficial  ownership
interests  in  a  separate  trust  created  under  that  pooling  and  servicing
agreement.  A trust will  consist  of, to the  extent  provided  in the  related
pooling and servicing agreement:

      mortgage loans and the related  mortgage  documents or interests  therein,
      including  any mortgage  securities,  underlying  a  particular  series of
      certificates as from time to time are subject to the pooling and servicing
      agreement,   exclusive   of,  if  specified  in  the  related   prospectus
      supplement,  any  Excluded  Spread  or  other  interest  retained  by  the
      depositor or any of its affiliates with respect to each Mortgage Loan

      assets including, without limitation, all payments and collections derived
      from the  mortgage  loans or  mortgage  securities  due after the  related
      cut-off  date,  as from time to time are  identified  as  deposited in the
      Custodial Account and in the related Certificate Account

      property  acquired by foreclosure of the mortgage loans or deed in lieu of
      foreclosure  and portions of the related  proceeds from the disposition of
      any related Additional Collateral or Pledged Assets

      hazard insurance policies and primary insurance policies, if any, and
      portions of the related proceeds; and

                                       4

<PAGE>

      any combination,  as and to the extent specified in the related prospectus
      supplement,  of a letter of credit,  purchase  obligation,  mortgage  pool
      insurance  policy,  special hazard insurance  policy,  bankruptcy  policy,
      certificate  insurance  policy,  surety  bond  or  other  type  of  credit
      enhancement as described under 'Description of Credit Enhancement.'

     The related  prospectus  supplement  will  describe the material  terms and
conditions of  certificates of interest or  participations  in mortgage loans to
the extent they are included in the related trust.

     Each  mortgage  loan will be selected by the  depositor  for inclusion in a
mortgage pool from among those  purchased by the depositor,  either  directly or
through its affiliates,  including Residential Funding Corporation, from sellers
who are affiliates of the depositor  including  HomeComings  Financial  Network,
Inc.  and  GMAC  Mortgage   Corporation,   or  from  banks,   savings  and  loan
associations,  mortgage bankers,  investment  banking firms, the Federal Deposit
Insurance  Corporation,  or FDIC, and other mortgage loan originators or sellers
not affiliated  with the depositor,  all as described in this  prospectus  under
'Mortgage  Loan  Program.'  If a mortgage  pool is composed  of  mortgage  loans
acquired by the depositor  directly from sellers other than Residential  Funding
Corporation,  the  related  prospectus  supplement  will  specify  the extent of
mortgage  loans so acquired.  The  characteristics  of the mortgage loans are as
described in the related prospectus  supplement.  No more than five percent (5%)
of the  mortgage  loans  (as they are  constituted  as of the  cut-off  date) by
aggregate  principal  balance as of the cut-off  date will have  characteristics
that deviate  from those  characteristics  described  in the related  prospectus
supplement.  Other  mortgage  loans  available for purchase by the depositor may
have characteristics  which would make them eligible for inclusion in a mortgage
pool but were not selected for inclusion in a mortgage pool at that time.

     The mortgage  loans may also be delivered to the  depositor in a Designated
Seller  Transaction.  Those  certificates may be sold in whole or in part to any
seller  identified  in the related  prospectus  supplement  in exchange  for the
related  mortgage  loans,  or may be  offered  under  any of the  other  methods
described  in this  prospectus  under  'Methods  of  Distribution.'  The related
prospectus   supplement  for  a  Designated  Seller   Transaction  will  include
information,  provided by the related  seller,  about the seller,  the  mortgage
loans and the underwriting  standards  applicable to the mortgage loans. None of
the depositor, Residential Funding Corporation, GMAC Mortgage Group, Inc. or any
of their affiliates will make any representation or warranty with respect to the
mortgage loans, or any  representation as to the accuracy or completeness of the
information provided by the seller.

     If specified in the related prospectus  supplement,  the trust underlying a
series of certificates may include mortgage securities.  The mortgage securities
may have been issued  previously  by the  depositor or an affiliate  thereof,  a
financial  institution  or other  entity  engaged in the  business  of  mortgage
lending or a limited  purpose  corporation  organized  for the purpose of, among
other things,  acquiring and depositing  mortgage loans into trusts, and selling
beneficial  interests  in such trusts.  As  specified in the related  prospectus
supplement,  the mortgage  securities  will primarily be similar to certificates
offered  hereunder.  As to any series of  certificates,  the related  prospectus
supplement will include a description of the mortgage securities and any related
credit enhancement,  and the mortgage loans underlying those mortgage securities
will be  described  together  with any  other  mortgage  loans  included  in the
mortgage pool relating to that series. As to any series of certificates, as used
in  this  prospectus  a  mortgage  pool  includes  the  related  mortgage  loans
underlying any mortgage securities.

     Any mortgage  securities  underlying any  certificates  will (i) either (a)
have  been  previously  registered  under  the  Securities  Act,  or (b) will be
eligible for sale under Rule 144(k) under the  Securities  Act, and (ii) will be
acquired in secondary market  transactions from persons other than the issuer or
its  affiliates.  Alternatively,  if the mortgage  securities were acquired from
their issuer or its  affiliates,  or were issued by the  depositor or any of its
affiliates, then the mortgage securities will be registered under the Securities
Act at the same time as the certificates.

     For any series of certificates  backed by mortgage  securities,  the entity
that administers the mortgage  securities may be referred to as the manager,  if
so specified in the related prospectus supplement. References in this prospectus
to Advances to be made and other  actions to be taken by the master  servicer in
connection  with the mortgage loans may include  Advances made and other actions
taken under the terms of the mortgage securities.

     As  specified  in the  applicable  prospectus  supplement,  each  series of
certificates  will evidence  interests in one mortgage pool  including  mortgage
loans having an aggregate principal balance of not less than

                                       5



<PAGE>



<PAGE>

approximately  $5,000,000 as of the cut-off date. Each certificate will evidence
an interest in only the related mortgage pool and  corresponding  trust, and not
in any other mortgage pool or trust.

THE MORTGAGE LOANS

     As  specified  in the related  prospectus  supplement,  all of the mortgage
loans in a mortgage pool will:

      have monthly payments due or deemed to be due on the first of each month

      be secured by mortgaged properties located in any of the 50 states or the
      District of Columbia, or be Puerto Rico mortgage loans and

      be of one or more types of the following types of mortgage loans described
      or referred to in paragraphs numbered (1) through (8):

          (1) Fixed-rate,  fully-amortizing  mortgage  loans,  which may include
     mortgage loans converted from  adjustable-rate  mortgage loans or otherwise
     modified,  providing for level  monthly  payments of principal and interest
     and terms at origination or modification of not more than 15 years;

          (2) Fixed-rate,  fully-amortizing  mortgage  loans,  which may include
     mortgage loans converted from  adjustable-rate  mortgage loans or otherwise
     modified,  providing for level  monthly  payments of principal and interest
     and terms at origination  or  modification  of more than 15 years,  but not
     more than 30 years;

          (3)  Fully-amortizing  adjustable-rate  mortgage  loans, or ARM loans,
     having an original  or modified  term to maturity of not more than 30 years
     with a related  interest rate which usually adjusts  initially  either one,
     three or six months,  one,  three,  five or seven years  subsequent  to the
     initial  payment date,  and  thereafter at either one,  three or six-month,
     one-year or other intervals,  with corresponding  adjustments in the amount
     of monthly  payments,  over the term of the mortgage loan to equal the Note
     Margin and an index.  The related  prospectus  supplement will describe the
     relevant  index and the highest,  lowest and  weighted  average Note Margin
     with  respect to the ARM loans in the related  mortgage  pool.  The related
     prospectus   supplement   will  also  indicate  any  periodic  or  lifetime
     limitations  on changes in any per annum  mortgage  rate at the time of any
     adjustment.  If specified in the related prospectus supplement, an ARM Loan
     may include a provision that allows the mortgagor to convert the adjustable
     mortgage  rate to a fixed  rate at some  point  during  the term of the ARM
     Loan, which in most cases will occur not later than ten years subsequent to
     the initial payment date;

          (4)   Negatively-amortizing   adjustable-rate  mortgage  loans  having
     original  or  modified  terms to  maturity  of not more than 30 years  with
     mortgage  rates  which  in most  cases  adjust  initially  on the  interest
     adjustment  date  referred to in the  related  prospectus  supplement,  and
     thereafter  on each interest  adjustment  date to equal the sum of the Note
     Margin and the index. The scheduled monthly payment will be adjusted as and
     when described in the related prospectus supplement to an amount that would
     fully  amortize the mortgage loan over its  remaining  term on a level debt
     service basis; provided that increases in the scheduled monthly payment may
     be  limited  as  specified  in the  related  prospectus  supplement.  If an
     adjustment  to the  mortgage  rate on a mortgage  loan causes the amount of
     interest  accrued  thereon  in any month to exceed  the  scheduled  monthly
     payment on the mortgage  loan,  the resulting  amount of deferred  interest
     will be added to the principal balance of that mortgage loan;

          (5) Fixed-rate,  graduated  payment  mortgage loans having original or
     modified terms to maturity of not more than 15 years with monthly  payments
     during the first year  calculated on the basis of an assumed  interest rate
     which is a specified  percentage  below the mortgage  rate on that mortgage
     loan. The monthly payments  increase at the beginning of the second year by
     a specified percentage of the monthly payment during the preceding year and
     each year thereafter to the extent  necessary to amortize the mortgage loan
     over the remainder of its 15-year term. Deferred interest,  if any, will be
     added to the principal balance of these mortgage loans;

          (6) Fixed-rate,  graduated  payment  mortgage loans having original or
     modified terms to maturity of not more than 30 years with monthly  payments
     during the first year  calculated on the basis of an assumed  interest rate
     which is a  specified  percentage  below the  mortgage  rate.  The  monthly
     payments  increase  at the  beginning  of the  second  year by a  specified
     percentage of the monthly  payment  during the preceding year and each year
     thereafter  to the extent  necessary to fully  amortize  the mortgage  loan
     within its 30-year term.  Deferred  interest,  if any, will be added to the
     principal balance of the mortgage loan;

                                       6



<PAGE>



<PAGE>

          (7)  Balloon  Loans.  The amount of the  monthly  payment  will remain
     constant until the maturity  date,  upon which date the Balloon Amount will
     be due and payable; or

          (8) Additional Collateral Loans, Buy-Down Mortgage Loans,  Convertible
     Mortgage Loans, Cooperative Loans, modified loans or Pledged Asset Mortgage
     Loans.

     If so specified in the related prospectus  supplement,  a mortgage pool may
contain mortgage loans that provide for payment of a prepayment charge.

     If so specified in the related prospectus supplement,  a mortgage pool will
contain Additional Collateral Loans. The Additional Collateral  Requirement will
generally terminate when the loan-to-value  ratio, or LTV ratio, of the mortgage
loan is reduced to a predetermined level, which generally shall not be more than
75%, as a result of a reduction in the loan amount caused by principal  payments
by the mortgagor  under the mortgage loan or an increase in the appraised  value
of the related mortgaged property.

     The seller of the Additional Collateral Loan or the related subservicer, as
applicable, will be required, in accordance with the master servicer's servicing
guidelines  or its  normal  servicing  procedures,  to attempt to realize on any
Additional  Collateral if the related  Additional  Collateral Loan is liquidated
upon default.  The right to receive  proceeds from the realization of Additional
Collateral  upon any  liquidation  will be assigned to the related  trustee.  No
assurance  can be given as to the  amount of  proceeds,  if any,  that  might be
realized from such Additional Collateral and thereafter remitted to the trustee.

     Unless  otherwise  specified  in  the  related  prospectus  supplement,  an
insurance company whose claims-paying  ability is rated in the highest long-term
rating  category  by  each  rating  agency  rating  the  applicable   series  of
certificates  will have  issued a  limited  purpose  surety  bond  insuring  any
deficiency in the amounts realized by the Additional Collateral Loan seller from
the  liquidation  of Additional  Collateral,  up to the amount of the Additional
Collateral Requirement.  For additional considerations concerning the Additional
Collateral  Loans,  see 'Certain Legal Aspects of Mortgage Loans -- The Mortgage
Loans --  Anti-Deficiency  Legislation and Other Limitations on Lenders' in this
prospectus.

     If so specified in the related prospectus  supplement,  a mortgage pool may
include  Pledged  Asset  Mortgage  Loans.  Each Pledged  Asset will be held by a
custodian  for the  benefit of the  trustee  for the trust in which the  related
Pledged  Asset  Mortgage  Loan is  held,  and  will be  invested  in  investment
obligations  permitted  by the  Rating  agencies  rating the  related  series of
certificates.  The amount of the Pledged Assets will be determined by the seller
in accordance with its  underwriting  standards,  but generally will not be more
than an amount that, if applied to reduce the original  principal balance of the
mortgage  loan,  would  reduce  that  principal  balance to less than 70% of the
appraised value of the mortgaged property.

     If, following a default by the mortgagor and the liquidation of the related
mortgaged  property,  there  remains a loss on the related  mortgage  loan,  the
limited  liability company will be required to pay to the master servicer or the
subservicer  on behalf of the trustee the amount of that loss, up to the pledged
amount for such mortgage loan. If the mortgagor becomes a debtor in a bankruptcy
proceeding,  there is a  significant  risk that the  Pledged  Assets will not be
available to be paid to the certificateholders.  At the mortgagor's request, and
in  accordance  with some  conditions,  the  Pledged  Assets may be applied as a
partial  prepayment of the mortgage loan. The Pledged Assets will be released to
the  limited  liability  company  if the  outstanding  principal  balance of the
mortgage loan has been reduced by the amount of the Pledged Assets.

     If so specified in the related prospectus  supplement,  a mortgage pool may
include mortgage loans that have been modified.  The  modifications  may include
conversions  from an adjustable to a fixed  mortgage rate  (discussed  below) or
other  changes in the related  mortgage  note.  If a mortgage loan is a modified
mortgage  loan,  references  to  origination  generally  shall be  deemed  to be
references to the date of modification.

     The  mortgaged  properties  may consist of detached  individual  dwellings,
cooperative  dwellings,  individual  condominiums,   townhouses,  duplexes,  row
houses, modular pre-cut/panelized housing,  individual units or two-to four-unit
dwellings in planned unit developments,  two- to four-family dwellings and other
attached  dwelling  units.  Each  mortgaged  property,  other than a Cooperative
dwelling,  will be located on land owned in fee simple by the  mortgagor  or, if
specified in the related  prospectus  supplement,  land leased by the mortgagor.
Attached  dwellings may include  structures  where each  mortgagor owns the land
upon which the unit is built with the  remaining  adjacent land owned in common,
or dwelling  units subject to a proprietary  lease or occupancy  agreement in an
apartment  building owned by a Cooperative.  The proprietary  lease or occupancy
agreement  securing a Cooperative  Loan is  subordinate,  in most cases,  to any
blanket mortgage on the related cooperative

                                       7



<PAGE>



<PAGE>

apartment building or on the underlying land. Additionally, in the case of a
Cooperative Loan, the proprietary lease or occupancy agreement may be terminated
and the cooperative shares may be canceled by the Cooperative if the
tenant-stockholder fails to pay maintenance or other obligations or charges owed
by the tenant-stockholder. See 'Certain Legal Aspects of Mortgage Loans.'

     The mortgaged  properties may be owner  occupied or non-owner  occupied and
may  include  vacation  homes,  second  homes  and  investment  properties.  The
percentage of mortgage  loans that are  owner-occupied  will be disclosed in the
related  prospectus  supplement.  The  basis  for  any  statement  that a  given
percentage of the mortgage  loans are secured by mortgaged  properties  that are
owner-occupied will be one or more of the following:

      the making of a representation by the mortgagor at origination of a
      mortgage loan that the mortgagor intends to use the mortgaged property as
      a primary residence,

      a   representation   by  the  originator  of  the  mortgage  loan,   which
      representation may be based solely on the above clause, or

      the fact that the  mailing  address for the  mortgagor  is the same as the
      address of the mortgaged property;  and any representation and warranty in
      the related pooling and servicing agreement regarding  owner-occupancy may
      be based solely on that information.

Mortgage  loans secured by investment  properties,  including  two- to four-unit
dwellings,  may also be  secured  by an  assignment  of  leases  and  rents  and
operating or other cash flow guarantees relating to the mortgage loans.

     In the  case of  purchase  mortgage  loans,  the LTV  ratio  is the  ratio,
expressed as a  percentage,  of the  principal  amount of the  mortgage  loan at
origination to the lesser of (1) the appraised value  determined in an appraisal
obtained at  origination  of the  mortgage  loan and (2) the sales price for the
related  mortgaged  property,  except  that  in the  case of  some  employee  or
preferred customer loans, the denominator of the ratio may be the sales price.

     In the  case of  some  non-purchase  mortgage  loans  including  refinance,
modified or converted mortgage loans, the LTV ratio at origination is defined in
most cases as the ratio,  expressed as a percentage,  of the principal amount of
the  mortgage  loan to either the  appraised  value  determined  in an appraisal
obtained  at the time of  refinancing,  modification  or  conversion  or,  if no
appraisal has been obtained,  the value of the related mortgaged  property which
value generally will be supported by either:

      a representation by the related seller as to the value

      a broker's price opinion, automated appraisal, drive by appraisal or other
      certification of value

      an appraisal  obtained  within  twelve  months  prior to the  refinancing,
      modification or conversion or, under the streamlined  refinancing  program
      described  herein,  an appraisal  obtained within  approximately 24 months
      prior to the refinancing or

      the sales price, if the mortgaged property was purchased within the
      previous twelve months.

     In the case of some mortgage loans seasoned for over twelve months, the LTV
ratio may be determined at the time of purchase from the related seller based on
the  ratio of the  current  loan  amount  to the  current  value of the  related
mortgaged property which value may be supported by either:

      a statistical analysis

      a broker's price opinion or

      an appraisal  obtained within 120 days of the purchase date, in which case
      the LTV ratio may be  significantly  lower  than the ratio  determined  at
      origination.

     The  denominator of the applicable  ratio  described in the preceding three
paragraphs is the appraised  value. In connection with a  representation  by the
related  seller as to the value of the  mortgaged  property,  the seller in most
cases will  represent  and  warrant  that  either (i) the  current  value of the
related  mortgaged  property  at  the  time  of  refinancing,   modification  or
conversion was not less than the appraised value of the related  property at the
time of the  origination  of the original  mortgage loan or (ii) the current LTV
ratio  of  the  mortgage  loan  generally  meets  the  depositor's  underwriting
guidelines.  There can be no assurance that the substance of that representation
and warranty will be true.

                                       8



<PAGE>



<PAGE>

     Some of the mortgage loans which are subject to negative  amortization will
have LTV  ratios  that  will  increase  after  origination  as a result of their
negative  amortization.  In the case of some seasoned mortgage loans, the values
used in  calculating  LTV ratios  may no longer be  accurate  valuations  of the
mortgaged properties, particularly where the LTV ratio was not determined at the
time  of  purchase  as  described  in the  four  preceding  paragraphs.  Certain
mortgaged  properties  may be located  in regions  where  property  values  have
declined significantly since the time of origination. In addition, the LTV ratio
does not take into  account  any  secondary  financing.  Under  the  depositor's
underwriting  standards,  a seller is usually  permitted  to  provide  secondary
financing to a mortgagor  contemporaneously  with the  origination of a mortgage
loan,  provided that the combined LTV ratio is not greater than 100%.  Secondary
financing is readily  available and may be obtained by a mortgagor from a lender
including the seller at any time, including at origination.

     The mortgage loans may be 'equity refinance'  mortgage loans, as to which a
portion of the proceeds are used to refinance an existing mortgage loan, and the
remaining  proceeds  may be  retained  by the  mortgagor  or used  for  purposes
unrelated to the mortgaged  property.  Alternatively,  the mortgage loans may be
'rate and term refinance'  mortgage loans, as to which  substantially all of the
proceeds, net of related costs incurred by the mortgagor,  are used to refinance
an existing mortgage loan or loans,  which may include a junior lien,  primarily
in order to change the  interest  rate or other terms of the  existing  mortgage
loan.

     The mortgage loans may be loans that have been consolidated and/or have had
various terms  changed,  loans that have been  converted  from  adjustable  rate
mortgage loans to fixed rate mortgage loans,  or  construction  loans which have
been converted to permanent  mortgage loans. In addition,  a mortgaged  property
may be subject to secondary financing at the time of origination of the mortgage
loan or at any time thereafter.

     If so  specified  in the related  prospectus  supplement,  a portion of the
proceeds of a mortgage loan may be held by the  originator and used to reimburse
the mortgagor for some costs of  construction  of or improvements to the related
mortgaged property.  The appraised value of this type of mortgaged property will
be based  on the  assumption  that  the  construction  has  been  completed;  no
inspections of the mortgaged  property will be made. If the  construction is not
completed, the actual value of the related mortgaged property could be adversely
affected and, even if the escrowed  proceeds are applied to reduce the principal
balance of the mortgage loan, the actual LTV ratio of the mortgage loan could be
higher than that assumed at the time of  origination  of the mortgage  loan.  In
addition, the application of any unused proceeds could cause the rate of payment
of principal on the mortgage loan to be faster than that assumed.

     A mortgage pool may contain Convertible Mortgage Loans. If specified in the
related  prospectus  supplement,   upon  any  conversion,   the  depositor  will
repurchase or Residential Funding Corporation,  the applicable  subservicer or a
third  party will  purchase  the  converted  mortgage  loan as and to the extent
described in the related prospectus supplement.  Alternatively,  if specified in
the  related  prospectus   supplement,   the  depositor,   Residential   Funding
Corporation or another party specified in the related prospectus  supplement may
agree to act as remarketing  agent with respect to the converted  mortgage loans
and,  in such  capacity,  to use its best  efforts  to  arrange  for the sale of
converted  mortgage loans under  specified  conditions.  Upon the failure of any
party so obligated to purchase any converted mortgage loan, the inability of any
remarketing agent to arrange for the sale of the converted mortgage loan and the
unwillingness of the remarketing  agent to exercise any election to purchase the
converted  mortgage  loan for its own account,  the related  mortgage  pool will
thereafter include both fixed rate and adjustable rate mortgage loans.

     If specified  in the related  prospectus  supplement,  some of the mortgage
loans may be Buy-Down  Mortgage  Loans under which the monthly  payments made by
the mortgagor during the Buy-Down Period will be less than the scheduled monthly
payments on the mortgage loan, the resulting difference to be made up from:

      Buy-Down Funds contributed by the seller of the mortgaged property or
      another source and placed in the Buy-Down Account;

      if the Buy-Down Funds are contributed on a present value basis, investment
      earnings on the Buy-Down Funds; or

      additional  buydown funds to be contributed  over time by the  mortgagor's
      employer or another source.

     See 'Description of the Certificates -- Payments on Mortgage Loans;
Deposits to Certificate Account.' Under Residential Funding Corporation's
underwriting standards, the mortgagor under each Buy-Down Mortgage Loan will be
qualified based on the initial reduced monthly payment amount. See 'Mortgage
Loan

Program --  Underwriting  Standards'  for a discussion  of loss and  delinquency
considerations relating to Buy-Down Mortgage Loans.

     The  related  prospectus   supplement  will  provide  material  information
concerning the types and  characteristics  of the mortgage loans included in the
related  mortgage  pool.  A Current  Report on Form 8-K will be  available  upon
request to  holders of the  related  series of  certificates  and will be filed,
together with the related  pooling and servicing  agreement  with the Securities
and Exchange  Commission  within fifteen days after the initial  issuance of the
certificates.  In the event that mortgage loans are added to or deleted from the
trust  after the date of the related  prospectus  supplement,  that  addition or
deletion will be noted in the Form 8-K.  Additions or deletions of this type, if
any, will be made prior to the closing date.

     The  depositor  will cause the mortgage  loans  constituting  each mortgage
pool, or mortgage securities evidencing interests therein, to be assigned to the
trustee  named in the  related  prospectus  supplement,  for the  benefit of the
holders of all of the certificates of a series. The master servicer named in the
related prospectus  supplement will service the mortgage loans,  usually through
subservicers  which are other mortgage servicing  institutions,  under a pooling
and servicing agreement and will receive a fee for such services.  See 'Mortgage
Loan Program' and 'Description of the Certificates.'

     With  respect to those  mortgage  loans  serviced  by the  master  servicer
through a subservicer,  the master servicer will remain liable for its servicing
obligations  under the related pooling and servicing  agreement as if the master
servicer alone were servicing those mortgage loans. In addition to or in lieu of
the  master  servicer  for a series  of  certificates,  the  related  prospectus
supplement  may  identify  a  Certificate   Administrator  for  the  trust.  All
references in this  prospectus  to master  servicer and any  discussions  of the
servicing and administration functions of the master servicer will also apply to
the Certificate Administrator to the extent applicable.

     The depositor will make a series of limited  representations and warranties
regarding the mortgage loans except as otherwise  specified in this  prospectus,
but its  assignment  of the  mortgage  loans  to the  trustee  will  be  without
recourse. See 'Description of the Certificates -- Assignment of Mortgage Loans.'

     The master  servicer's  obligations with respect to the mortgage loans will
consist principally of its contractual  servicing  obligations under the related
pooling and  servicing  agreement,  including  its  obligation  to enforce  some
purchase and other obligations of subservicers and sellers, as described in this
prospectus  under  'Mortgage Loan Program --  Representations  by Sellers,' ' --
Subservicing'  and  'Description  of the  Certificates  --  Assignment  of Trust
Assets,' and its obligation to make cash advances in the event of  delinquencies
in payments on or with  respect to the  mortgage  loans in amounts  described in
this prospectus  under  'Description of the  Certificates -- Advances,' or under
the terms of any mortgage  securities.  The obligation of the master servicer to
make  Advances  will be limited to amounts  which the master  servicer  believes
ultimately  would be  reimbursable  out of the  proceeds of  liquidation  of the
mortgage loans or any applicable form of credit support. See 'Description of the
Certificates -- Advances.'

                             MORTGAGE LOAN PROGRAM

     The  mortgage  loans  will have been  purchased  by the  depositor,  either
directly or indirectly through  Residential Funding  Corporation,  from sellers.
The mortgage loans will have been  originated in accordance with the depositor's
underwriting standards or alternative underwriting criteria as described in this
section under 'Underwriting Standards' or as described in the related prospectus
supplement.

UNDERWRITING STANDARDS

  General Standards

     The depositor's  underwriting  standards with respect to the mortgage loans
will conform to those  published in  Residential  Funding  Corporation's  Client
Guide,  as  application  to the 'Jumbo A' program.  The  underwriting  standards
contained in the Client Guide are  continuously  revised based on  opportunities
and prevailing  conditions in the residential mortgage market and the market for
the depositor's mortgage  pass-through  certificates.  The mortgage loans may be
underwritten by Residential  Funding Corporation or by a designated third party.
In some circumstances,  however,  the mortgage loans may be underwritten only by
the  seller.  See  ' --  Client  Guide  Standards'  and ' --  Qualifications  of
Sellers.' Residential Funding Corporation may perform

                                       10

only sample quality assurance reviews to determine whether the mortgage loans in
any mortgage pool were underwritten in accordance with applicable standards.

     With  respect to the  depositor's  underwriting  standards,  as well as any
other  underwriting  standards that may be applicable to any mortgage loans, the
underwriting  standards  include  a set of  specific  criteria  under  which the
underwriting  evaluation  is made.  However,  the  application  of  underwriting
standards   does  not  imply  that  each   specific   criterion   was  satisfied
individually.  Rather,  a mortgage  loan will be  considered to be originated in
accordance  with a given set of  underwriting  standards if, based on an overall
qualitative  evaluation,   the  loan  is  in  substantial  compliance  with  the
underwriting standards. For example, a mortgage loan may be considered to comply
with a set of  underwriting  standards,  even if one or more  specific  criteria
included in such  underwriting  standards were not  satisfied,  if other factors
compensated  for the criteria that were not satisfied or if the mortgage loan is
considered to be in substantial compliance with the underwriting standards.

     In addition, the depositor purchases mortgage loans which do not conform to
the  underwriting  standards  contained  in the Client  Guide.  A portion of the
mortgage  loans  will be  purchased  in  negotiated  transactions,  which may be
governed  by master  commitment  agreements  relating  to ongoing  purchases  of
mortgage  loans  by  Residential  Funding  Corporation,  from  sellers  who will
represent  that the  mortgage  loans have been  originated  in  accordance  with
underwriting standards agreed to by Residential Funding Corporation. Residential
Funding  Corporation,  on behalf of the  depositor,  will  review only a limited
portion  of the  mortgage  loans in any  delivery  from the  related  seller for
conformity with the applicable underwriting standards. A portion of the mortgage
loans will be purchased  from sellers who will represent that the mortgage loans
were  originated  pursuant to  underwriting  standards  determined by a mortgage
insurance  company or third party  origination  system acceptable to Residential
Funding Corporation. The depositor, or Residential Funding Corporation on behalf
of the  depositor,  may accept a  certification  from an insurance  company or a
confirmation by a third party as to a mortgage loan's insurability in a mortgage
pool as of the date of  certification  or confirmation as evidence of a mortgage
loan conforming to applicable  underwriting  standards.  Such  certifications or
confirmations  will likely have been issued  before the purchase of the mortgage
loan by Residential Funding Corporation or the depositor.

     The level of review by Residential Funding Corporation or the depositor, if
any,  of any  mortgage  loan for  conformity  with the  applicable  underwriting
standards will vary depending on any one of a number of factors, including:

      factors relating to the experience and status of the seller

      characteristics of the specific mortgage loan, including the principal
      balance, the LTV ratio, the loan type or loan program and

      the  applicable  credit score of the related  mortgagor used in connection
      with the origination of the mortgage loan, as determined based on a credit
      scoring model acceptable to the depositor.

Credit scoring models  provide a means for  evaluating the  information  about a
prospective  borrower  that is available  from a credit  reporting  agency.  The
underwriting  criteria  applicable to any program under which the mortgage loans
may be originated and reviewed may provide that  qualification  for the loan, or
the  availability  of various  loan  features,  including  maximum  loan amount,
maximum LTV ratio, property type and use, and documentation level, may depend on
the borrower's credit score.

     The underwriting  standards utilized in negotiated  transactions and master
commitments,   the  underwriting   standards  of  insurance   companies  issuing
certificates  and  the  underwriting  standards  applicable  to  mortgage  loans
underlying  mortgage  securities may vary  substantially  from the  underwriting
standards  contained  in the Client  Guide.  Those  underwriting  standards  are
generally  intended to provide an underwriter  with  information to evaluate the
borrower's  repayment  ability  and the  adequacy of the  mortgaged  property as
collateral.  Due to the variety of underwriting  standards and review procedures
that may be applicable to the mortgage  loans included in any mortgage pool, the
related prospectus  supplement  generally will not distinguish among the various
underwriting  standards applicable to the mortgage loans nor describe any review
for compliance with applicable underwriting standards performed by the depositor
or Residential  Funding  Corporation.  Moreover,  there can be no assurance that
every   mortgage  loan  was   originated  in  conformity   with  the  applicable
underwriting  standards  in all  material  respects,  or  that  the  quality  or
performance  of mortgage  loans  underwritten  pursuant to varying  underwriting
standards  will  be  equivalent  under  all  circumstances.  In  the  case  of a
Designated Seller  Transaction,  the applicable  underwriting  standards will be
those of the seller or of the  originator  of the  mortgage  loans,  and will be
described in the related prospectus supplement.

     The depositor,  either directly or indirectly through  Residential  Funding
Corporation,  will also purchase  mortgage loans from its affiliates,  including
GMAC  Mortgage  Corporation  and  HomeComings  Financial  Network,   Inc.,  with
underwriting  standards  in  accordance  with the Client  Guide or as  otherwise
agreed to by the depositor. However, in some limited circumstances, the mortgage
loans may be employee or  preferred  customer  loans with  respect to which,  in
accordance with the related affiliate's  mortgage loan programs,  income,  asset
and employment  verifications  and  appraisals may not have been required.  With
respect to mortgage  loans made under any employee  loan program  maintained  by
Residential Funding  Corporation,  or its affiliates,  in limited  circumstances
preferential  interest rates may be allowed,  and primary insurance policies may
not be  required in  connection  with an LTV ratio over 80%. As to any series of
certificates  representing  interests in such mortgage loans, credit enhancement
may be provided  covering  losses on the mortgage loans to the extent that these
losses would be covered by primary insurance  policies if obtained,  in the form
of a corporate  guaranty or in other forms  described in this  prospectus  under
'Description  of Credit  Enhancement.'  Neither the  depositor  nor  Residential
Funding  Corporation  will review any affiliate's  mortgage loans for conformity
with the underwriting standards contained in the Client Guide.

  Client Guide Standards

     The  following is a brief  description  of the  underwriting  standards set
forth in the Client Guide for full  documentation  loan programs.  Initially,  a
prospective  borrower,  other  than a trust  if the  trust is the  borrower,  is
required  to  fill  out  a  detailed  application   providing  pertinent  credit
information.  As part of the application,  the borrower is required to provide a
current  balance  sheet  describing  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 history with merchants and lenders and
any record of bankruptcy.  In addition,  an employment  verification is obtained
which  reports  the  borrower's  current  salary and may  contain  the length of
employment and an indication as to whether it is expected that the borrower will
continue  that  employment  in  the  future.   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  accounts.  In the case of a
mortgage loan secured by a property owned by a trust,  the foregoing  procedures
may be waived where the mortgage note is executed on behalf of the trust.

     In determining  the adequacy of the mortgaged  property as  collateral,  an
appraisal is made of each property  considered for  financing.  The appraiser is
required to verify that the property is in good condition and that construction,
if new, has been completed. The appraisal is based on various factors, including
the market value of comparable homes and the cost of replacing the improvements.
Alternatively,  property  valuations may be made under various other methods, as
described in this prospectus under 'The Trusts -- The Mortgage Loans.'

     Credit  Scores are obtained by many  mortgage  lenders in  connection  with
mortgage loan  applications  to help assess a borrower's  credit-worthiness.  In
addition, Credit Scores may be obtained by Residential Funding Corporation after
the origination of a mortgage loan if the seller does not provide to Residential
Funding  Corporation  a Credit  Score.  Credit  Scores are obtained  from credit
reports  provided by various credit reporting  organizations,  each of which may
employ differing computer models and methodologies.

     The Credit  Score is designed to assess a  borrower's  credit  history at a
single  point in time,  using  objective  information  currently on file for the
borrower at a particular credit reporting organization. Credit Scores range from
approximately  350 to  approximately  840,  with  higher  scores  indicating  an
individual with a more favorable credit history compared to an individual with a
lower score.  However,  a Credit Score  purports only to be a measurement of the
relative degree of risk a borrower represents to a lender, i.e., a borrower with
a higher score is statistically expected to be less likely to default in payment
than a borrower with a lower score. In addition,  it should be noted that Credit
Scores were developed to indicate a level of default probability over a two-year
period,  which does not correspond to the life of a mortgage loan.  Furthermore,
Credit  Scores  were  not  developed  specifically  for use in  connection  with
mortgage  loans,  but for  consumer  loans  in  general,  and  assess  only  the
borrower's  past credit history.  Therefore,  in most cases, a Credit Score does
not take into consideration the differences  between mortgage loans and consumer
loans, or the specific  characteristics of the related mortgage loan,  including
the LTV ratio,  the  collateral  for the  mortgage  loan,  or the debt to income
ratio.  There can be no assurance that the Credit Scores of the mortgagors  will
be an accurate  predictor of the likelihood of repayment of the related mortgage
loans or that any mortgagor's  Credit Score would not be lower if obtained as of
the date of the related prospectus supplement.

     Once  all  applicable  employment,   credit  and  property  information  is
received,  a determination  is made as to whether the  prospective  borrower has
sufficient monthly income available to meet the borrower's  monthly  obligations
on the proposed mortgage loan and other expenses related to the home,  including
property taxes and hazard insurance, and other financial obligations and monthly
living  expenses.  The depositor will  underwrite ARM loans,  Buy-Down  Mortgage
Loans,  graduated  payment  mortgage  loans and any other  mortgage loans on the
basis of the  borrower's  ability to make  monthly  payments  as  determined  by
reference to the mortgage rates in effect at origination or the reduced  initial
monthly payments, as the case may be, and on the basis of an assumption that the
borrowers will likely be able to pay the higher monthly payments that may result
from  later  increases  in the  mortgage  rates or from later  increases  in the
monthly  payments,  as the case may be, at the time of the increase  even though
the  borrowers  may not be  able to make  the  higher  payments  at the  time of
origination.  The mortgage  rate in effect from the  origination  date of an ARM
loan or other  types of loans to the  first  adjustment  date are  likely  to be
lower, and may be significantly lower, than the sum of the then applicable index
and Note  Margin.  Similarly,  the amount of the  monthly  payment  on  Buy-Down
Mortgage Loans and graduated payment mortgage loans will increase  periodically.
If the  borrowers'  incomes do not increase in an amount  commensurate  with the
increases in monthly  payments,  the  likelihood  of default will  increase.  In
addition,  in the case of either ARM loans or graduated  payment  mortgage loans
that are  subject to  negative  amortization,  due to the  addition  of deferred
interest the principal balances of those mortgage loans are more likely to equal
or exceed the value of the underlying mortgaged  properties,  thereby increasing
the likelihood of defaults and losses. With respect to Balloon Loans, payment of
the Balloon Amount will depend on the borrower's  ability to obtain  refinancing
or to sell the mortgaged property prior to the maturity of the Balloon Loan, and
there can be no assurance that  refinancing will be available to the borrower or
that a sale will be possible.

     If so specified in the related prospectus  supplement,  a mortgage pool may
include  mortgage  loans that have been  underwritten  pursuant to a streamlined
documentation  refinancing program,  contained in the Client Guide. This program
permits  mortgage  loans to be  refinanced  with only  limited  verification  or
updating of the underwriting  information that was obtained at the time that the
original  mortgage  loan was  originated.  For example,  a new  appraisal of the
mortgaged  property  may not be required  if the  refinanced  mortgage  loan was
originated up to approximately 24 months prior to the refinancing.  In addition,
the mortgagor's  income may not be verified,  although  continued  employment is
required to be verified. In some cases, the mortgagor may be permitted to borrow
up to 105% of the outstanding  principal  amount of the original  mortgage loan.
Each  mortgage  loan  underwritten  pursuant to this  program will be treated as
having been underwritten pursuant to the same underwriting documentation program
as  the  mortgage  loan  that  it  refinanced,  including  for  purposes  of the
disclosure in the related prospectus supplement.

     The underwriting  standards set forth in the Client Guide will be varied in
appropriate cases, including 'limited' or 'reduced loan documentation'  mortgage
loan programs.  Some reduced loan documentation  programs,  for example,  do not
require income, employment or asset verifications. In most cases, in order to be
eligible  for a reduced  loan  documentation  program,  the LTV ratio  must meet
applicable  guidelines,  the  borrower  must have a good credit  history and the
borrower's  eligibility  for this type of program may be  determined by use of a
credit scoring model.

     To the extent the seller fails or is unable to repurchase any mortgage loan
due to a  breach  of a  representation  and  warranty,  neither  the  depositor,
Residential  Funding  Corporation  nor any other  entity  will be so  obligated.
Furthermore,  to the extent that the  appraised  value of the related  mortgaged
property has  declined,  the actual LTV ratio with respect to such mortgage loan
will be higher than the LTV ratio set forth with respect  thereto in the related
prospectus supplement.

     In its  evaluation  of mortgage  loans that have more than twelve months of
payment  experience,  Residential  Funding  Corporation  tends to place  greater
weight on payment  history and may take into account  market and other  economic
trends while placing less weight on underwriting factors  traditionally  applied
to newly originated mortgage loans. Some mortgage loans seasoned for over twelve
months may be underwritten for purchase by Residential Funding Corporation based
on the  borrower's  credit  score and payment  history,  with no current  income
verification, and under alternative property valuation methods described in this
prospectus under 'The Trusts -- The Mortgage Loans.'

     The  mortgaged  properties  may be located in states where,  in general,  a
lender  providing  credit on a single-family  property may not seek a deficiency
judgment against the mortgagor but rather must look solely to the

                                       13

<PAGE>

property for repayment in the event of  foreclosure.  See 'Certain Legal Aspects
of Mortgage Loans -- The Mortgage Loans -- Anti-Deficiency Legislation and Other
Limitations on Lenders.' The depositor's  underwriting  standards  applicable to
all states,  including  anti-deficiency  states,  require  that the value of the
property being financed,  as indicated by the appraisal,  currently supports and
is anticipated to support in the future the outstanding  loan balance,  although
there can be no  assurance  that the value will  support the loan balance in the
future.

QUALIFICATIONS OF SELLERS

     Except with respect to Designated Seller  Transactions,  each seller, other
than  the FDIC  and  investment  banking  firms,  will  have  been  approved  by
Residential   Funding  Corporation  for  participation  in  Residential  Funding
Corporation's loan purchase program.  In determining whether to approve a seller
for participation in the loan purchase program,  Residential Funding Corporation
will  consider,  among other  things,  the financial  status,  including the net
worth,  of the seller,  the  previous  experience  of the seller in  originating
mortgage loans,  the prior  delinquency  and loss experience of the seller,  the
underwriting  standards  employed by the seller and the quality  control and, if
applicable,  the servicing operations established by the seller. There can be no
assurance that any seller presently meets any qualifications or will continue to
meet any qualifications at the time of inclusion of mortgage loans sold by it in
the trust for a series  of  certificates,  or  thereafter.  If a seller  becomes
subject to the  direct or  indirect  control  of the FDIC or if a  seller's  net
worth,  financial  performance or delinquency and foreclosure rates deteriorate,
that institution may continue to be treated as a seller.  Any event of this type
may adversely  affect the ability of any seller to repurchase  mortgage loans in
the event of a breach of a representation or warranty which has not been cured.

     Residential Funding Corporation  monitors sellers that it knows to be under
control  of  the  FDIC  or  are   insolvent,   otherwise  in   receivership   or
conservatorship or financially  distressed.  Any seller that is under control of
the FDIC or insolvent may make no representations and warranties with respect to
mortgage  loans sold by it. The FDIC,  either in its  corporate  capacity  or as
receiver  for a  depository  institution,  may also be a seller of the  mortgage
loans,  in which event neither the FDIC nor the related  depository  institution
may make representations and warranties with respect to the mortgage loans sold,
or only limited  representations  and warranties may be made, for example,  that
the related legal documents are enforceable.

     As  specified  in the related  prospectus  supplement,  the  qualifications
required  of  sellers  for  approval  by  Residential   Funding  Corporation  as
participants  in its  loan  purchase  programs  may  not  apply  to  sellers  in
Designated Seller Transactions.  To the extent the seller in a Designated Seller
Transaction  fails to or is  unable to  repurchase  any  mortgage  loan due to a
breach of  representation  and  warranty,  neither  the  depositor,  Residential
Funding  Corporation nor any other entity will have assumed the  representations
and warranties and any related losses will be borne by the certificateholders or
by the credit enhancement, if any.

REPRESENTATIONS BY SELLERS

     Except as described in the two preceding paragraphs,  each seller will make
representations  and  warranties  with respect to the mortgage  loans sold by it
directly or indirectly to the  depositor.  The  representations  and  warranties
generally  include,  among  other  things,  that at the  time of the sale by the
seller to Residential Funding Corporation of each mortgage loan:

      except in the case of Cooperative Loans,  title insurance,  or in the case
      of mortgaged properties located in areas where such policies are generally
      not  available,  an attorney's  certificate  of title,  or another form of
      coverage in lieu of title insurance as specified in the related prospectus
      supplement,  and any required hazard and primary  mortgage  insurance were
      effective at the  origination  of each mortgage  loan,  and each policy or
      certificate  of title  remained  in effect on the date of purchase of each
      mortgage  loan from the seller by the  depositor  or  Residential  Funding
      Corporation

      the seller has good title to each mortgage loan and each mortgage loan was
      subject to no offsets, defenses or counterclaims except as may be provided
      under the  Soldiers'  and Sailors'  Relief Act of 1940, or Relief Act, and
      except to the  extent  that any  buydown  agreement  exists for a Buy-Down
      Mortgage Loan

                                       14

      there are no  mechanics'  liens or  claims  for  work,  labor or  material
      affecting any mortgaged  property which are, or may be a lien prior to, or
      equal with, the lien of the related  mortgage  subject only to permissible
      title insurance exceptions

      each mortgaged property is free from damage and in good repair

      there are no delinquent tax or, to the best of the seller's knowledge,
      assessment liens against the mortgaged property

      each mortgage loan is current as to all required payments

      if a primary insurance policy is required with respect to a mortgage loan,
      the mortgage loan is the subject of a primary insurance policy; and

      each mortgage loan was made in compliance with, and is enforceable  under,
      all applicable local, state and federal laws in all material respects.

     In the event of a breach of a  seller's  representation  or  warranty  that
materially  adversely  affects  the  interests  of the  certificateholders  in a
mortgage loan, the related seller will be obligated to repurchase  that mortgage
loan  as  described  in  this   prospectus   under  'Mortgage  Loan  Program  --
Representations  by Sellers.'  However,  there can be no assurance that a seller
will honor its  obligation to repurchase any mortgage loan as to which that type
of breach of a  representation  or warranty  arises.  Any costs  associated with
enforcing the seller's obligation to repurchase that mortgage loan will be borne
by the related trust.

     Each seller will have  represented with respect to a mortgage loan that any
modification  agreement  was  recorded as  necessary  to preserve the first lien
position in the jurisdiction in which the mortgaged property is located.  If the
mortgage loans include  Cooperative  Loans or if an alternative form of coverage
in lieu of title  insurance was obtained,  representations  and warranties  with
respect to title insurance or hazard  insurance may not be given. In most cases,
the Cooperative  itself is responsible  for the maintenance of hazard  insurance
for property owned by the Cooperative,  and the borrowers  (tenant-stockholders)
of the Cooperative do not maintain hazard insurance on their individual dwelling
units.

     All of  the  representations  and  warranties  of a  seller  relating  to a
mortgage  loan will have been made as of the date on which that  seller sold the
mortgage loan to the depositor or Residential Funding  Corporation;  the date as
of which the  representations  and warranties  were made will be a date prior to
the date of initial  issuance of the related series of  certificates  or, in the
case of a  Designated  Seller  Transaction,  will be the date of  closing of the
related sale by the  applicable  seller.  A substantial  period of time may have
elapsed  between the date as of which the  representations  and warranties  were
made  and  the  later  date  of  initial  issuance  of  the  related  series  of
certificates. Accordingly, the seller's purchase obligation, or, if specified in
the related prospectus supplement,  limited replacement option,  described below
will  not  arise  if,  during  the  period  commencing  on the date of sale of a
mortgage loan by the seller to the depositor or Residential Funding Corporation,
an event occurs that would have given rise to such an  obligation  had the event
occurred prior to sale of the affected mortgage loan.

     In the case of a mortgage pool  consisting of mortgage  loans  purchased by
the depositor from sellers through Residential Funding Corporation,  Residential
Funding Corporation, except in the case of a Designated Seller Transaction or as
to  mortgage  loans  underlying  any  mortgage  securities,  will also have made
limited  representations  and  warranties  regarding  the mortgage  loans to the
depositor at the time, just prior to the initial  issuance of the related series
of certificates,  that they are sold to the depositor. These representations and
warranties will include, among other things, that:

      as of the cut-off date, the information set forth in a listing of the
      related mortgage loans is true and correct in all material respects;

      except  in the  case of  Cooperative  Loans,  either  a  policy  of  title
      insurance  in the form  and  amount  required  by the  Client  Guide or an
      equivalent  protection  was effective at the  origination of each mortgage
      loan,  and each  policy  remained  in full force and effect on the date of
      sale of the mortgage loan to the depositor;

      to the best of Residential Funding Corporation's knowledge, if required,
      the mortgage loans are the subject of a primary insurance policy;

                                       15

      Residential  Funding  Corporation had good title to each mortgage loan and
      each  mortgage  loan is subject to no offsets,  defenses or  counterclaims
      except as may be provided  under the Relief Act and except with respect to
      any buydown agreement for a Buy-Down Mortgage Loan;

      each mortgaged property is free of damage and is in good repair;

      each mortgage loan complied in all material  respects with all  applicable
      local, state and federal laws at the time of origination;

      except as otherwise  indicated in the related  prospectus  supplement,  no
      mortgage  loan is 30 or more days  delinquent  in payment of principal and
      interest as of the related  cut-off  date and was not so  delinquent  more
      than once during the twelve-month period prior to the cut-off date; and

      there  is no  delinquent  tax  or,  to the  best  of  Residential  Funding
      Corporation's knowledge, assessment lien against any mortgaged property.

     In  the  event  of a  breach  of  a  representation  or  warranty  made  by
Residential Funding Corporation that materially  adversely affects the interests
of the  certificateholders  in a mortgage loan,  Residential Funding Corporation
will be  obligated  to  repurchase  or  substitute  for  that  mortgage  loan as
described below. In addition,  Residential Funding Corporation will be obligated
to repurchase or substitute for as described below any mortgage loan as to which
it is  discovered  that the  related  mortgage  is not a valid first lien on the
related mortgaged  property subject only to (a) liens of real property taxes and
assessments not yet due and payable, (b) covenants, conditions and restrictions,
rights of way,  easements  and other  matters of public record as of the date of
recording of the mortgage and other  permissible  title exceptions and (c) other
matters to which like  properties  are commonly  subject which do not materially
adversely  affect the value,  use,  enjoyment or  marketability of the mortgaged
property.

     In addition,  with respect to any mortgage  loan as to which the  depositor
delivers  to the  trustee or the  custodian  an  affidavit  certifying  that the
original  mortgage  note  has  been  lost or  destroyed,  if the  mortgage  loan
subsequently  is in default and the  enforcement  of the mortgage loan or of the
related mortgage is materially adversely affected by the absence of the original
mortgage note,  Residential  Funding Corporation will be obligated to repurchase
or substitute for that mortgage loan in the manner  described in this prospectus
under  'Mortgage  Loan  Program  --   Representations   by  Sellers'.   However,
Residential Funding Corporation will not be required to repurchase or substitute
for any mortgage loan if the circumstances  giving rise to that requirement also
constitute fraud in the origination of the related  mortgage loan.  Furthermore,
because the listing of the related mortgage loans generally contains information
with respect to the mortgage loans as of the cut-off date,  prepayments  and, in
limited  circumstances,  modifications  to the interest  rate and  principal and
interest  payments may have been made with respect to one or more of the related
mortgage  loans  between  the  cut-off  date  and  the  closing  date.   Neither
Residential  Funding  Corporation nor any seller will be required to purchase or
substitute  for any  mortgage  loan as a result  of this type of  prepayment  or
modification.

     The depositor  will assign to the trustee for the benefit of the holders of
the related series of certificates all of its right,  title and interest in each
agreement  by which it  purchased  a  mortgage  loan  from  Residential  Funding
Corporation  insofar  as  the  agreement  relates  to  the  representations  and
warranties made by a seller or Residential Funding Corporation,  as the case may
be, relating to the mortgage loan and any remedies  provided for with respect to
any breach of the  representations  and  warranties.  If a seller or Residential
Funding  Corporation,  as  the  case  may  be,  cannot  cure  a  breach  of  any
representation  or  warranty  made by it in  respect  of a  mortgage  loan which
materially and adversely affects the interests of the certificateholders in that
mortgage loan within 90 days after notice from the master  servicer,  the seller
or  Residential  Funding  Corporation,  as the case may be, will be obligated to
purchase  the  mortgage  loan at the  purchase  price set  forth in the  related
pooling and servicing agreement which purchase price will in most cases be equal
to the  principal  balance  thereof as of the date of purchase  plus accrued and
unpaid  interest to the first day of the month following the month of repurchase
at the mortgage  rate,  less the amount,  expressed  as a percentage  per annum,
payable  as master  servicing  compensation  or  subservicing  compensation,  as
applicable, and, if applicable, the Excluded Spread.

     As to any mortgage  loan  required to be purchased by  Residential  Funding
Corporation  as  provided  above,  rather than  repurchase  the  mortgage  loan,
Residential  Funding  Corporation  may, at its sole  option,  remove the deleted
mortgage  loan from the trust and cause the depositor to substitute in its place
a  qualified  substitute  mortgage  loan;  however,  this  substitution  must be
effected within 120 days of the date of the initial issuance of

                                       16

<PAGE>

the  certificates  with respect to a trust for which no REMIC  election is to be
made.  With respect to a trust for which a REMIC election is to be made,  except
as  otherwise  provided  in the  prospectus  supplement  relating to a series of
certificates,  any  substitution  of a defective  mortgage loan must be effected
within two years of the date of the initial  issuance of the  certificates,  and
may not be made if the  substitution  would  cause the trust to not qualify as a
REMIC or result in a prohibited transaction tax under the Internal Revenue Code.

     Any  qualified  substitute  mortgage  loan  generally  will, on the date of
substitution:

      have an outstanding  principal  balance,  after deduction of the principal
      portion of the monthly  payment due in the month of  substitution,  not in
      excess of the outstanding  principal balance of the deleted mortgage loan,
      with the amount of any shortfall to be deposited in a Custodial Account in
      the month of substitution for distribution to the certificateholders;

      have a mortgage rate and a Net Mortgage  Rate not less than,  and not more
      than one percentage point greater than, the mortgage rate and Net Mortgage
      Rate,  respectively,  of the  deleted  mortgage  loan  as of the  date  of
      substitution;

      have an LTV ratio at the time of substitution no higher than that of the
      deleted mortgage loan at the time of substitution;

      have a remaining  term to maturity not greater than, and not more than one
      year less than, that of the deleted mortgage loan; and

      comply with all of the  representations  and  warranties  set forth in the
      related pooling and servicing agreement as of the date of substitution.

     The  related  pooling  and  servicing   agreement  may  include  additional
requirements relating to ARM loans or other specific types of mortgage loans, or
additional  provisions  relating to meeting  the  foregoing  requirements  on an
aggregate basis where a number of substitutions occur contemporaneously.  Unless
otherwise specified in the related prospectus supplement,  a seller, including a
seller in a Designated Seller Transaction, will have no option to substitute for
a mortgage loan that it is obligated to  repurchase in connection  with a breach
of a representation and warranty.

     The master  servicer  will be  required  under the  applicable  pooling and
servicing  agreement to use its best reasonable efforts to enforce this purchase
or   substitution   obligation   for  the   benefit  of  the   trustee  and  the
certificateholders,  using  practices it would employ in its good faith business
judgment  and  which are  normal  and usual in its  general  mortgage  servicing
activities;  provided,  however,  that this purchase or substitution  obligation
will not become an obligation of the master  servicer in the event the seller or
Residential  Funding  Corporation,  as the  case may be,  fails  to  honor  that
obligation.  The master servicer will be entitled to reimbursement for any costs
and  expenses  incurred in pursuing  any  purchase or  substitution  obligation,
including but not limited to any costs or expenses  associated with  litigation.
In instances where a seller is unable,  or disputes its obligation,  to purchase
affected mortgage loans, the master servicer,  employing the standards described
in the preceding  sentence,  may negotiate and enter into one or more settlement
agreements  with that seller that could  provide for,  among other  things,  the
purchase of only a portion of the  affected  mortgage  loans or coverage of some
loss amounts.  Any such  settlement  could lead to losses on the mortgage  loans
which would be borne by the related  credit  enhancement,  and to the extent not
available, on the related certificates.

     Furthermore, the master servicer may pursue foreclosure or similar remedies
concurrently  with  pursuing  any  remedy for a breach of a  representation  and
warranty.  However,  the master  servicer is not  required to continue to pursue
both  remedies  if it  determines  that one remedy is more likely to result in a
greater recovery.  In accordance with the above described practices,  the master
servicer  will not be required to enforce any  purchase  obligation  of a seller
arising  from  any  misrepresentation  by the  seller,  if the  master  servicer
determines in the reasonable  exercise of its business judgment that the matters
related to the  misrepresentation  did not  directly  cause or are not likely to
directly  cause a loss on the  related  mortgage  loan.  If the seller  fails to
repurchase  and no breach of  either  the  depositor's  or  Residential  Funding
Corporation's  representations  has occurred,  the seller's purchase  obligation
will  not  become  an  obligation  of  the  depositor  or  Residential   Funding
Corporation.  In the case of a Designated  Seller  Transaction  where the seller
fails to  repurchase  a mortgage  loan and  neither the  depositor,  Residential
Funding  Corporation  nor any other entity has assumed the  representations  and
warranties,  the  repurchase  obligation  of  the  seller  will  not  become  an
obligation of the depositor or Residential  Funding  Corporation.  The foregoing
obligations will constitute the sole remedies available to certificateholders or
the trustee  for a breach of any  representation  by a seller or by  Residential
Funding

                                       17

Corporation in its capacity as a seller of mortgage  loans to the depositor,  or
for any other event giving rise to the obligations.

     Neither the depositor nor the master servicer will be obligated to purchase
a  mortgage  loan  if a  seller  defaults  on its  obligation  to do so,  and no
assurance  can be given that the sellers will carry out those  obligations  with
respect to mortgage loans.  This type of default by a seller is not a default by
the depositor or by the master servicer. However, to the extent that a breach of
the  representations  and warranties of a seller also  constitutes a breach of a
representation  made by Residential  Funding,  or by the depositor or the master
servicer, as described in this prospectus under 'Description of the Certificates
- -- Assignment of Mortgage Loans,' Residential Funding Corporation, the depositor
or the master  servicer  may have a purchase  or  substitution  obligation.  Any
mortgage  loan not so purchased or  substituted  for shall remain in the related
trust and any losses  related  thereto shall be allocated to the related  credit
enhancement, and to the extent not available, to the related certificates.

     Notwithstanding  the  foregoing,  with respect to any seller that  requests
Residential Funding Corporation's consent to the transfer of subservicing rights
relating to any  mortgage  loans to a successor  servicer,  Residential  Funding
Corporation may release that seller from liability under its representations and
warranties described above, upon the assumption of the successor servicer of the
seller's  liability for the  representations  and warranties as of the date they
were made. In that event,  Residential  Funding  Corporation's  rights under the
instrument by which the successor  servicer assumes the seller's  liability will
be assigned to the trustee, and the successor servicer shall be deemed to be the
'seller' for purposes of the foregoing provisions.

SUBSERVICING

     The seller of a mortgage loan will usually act as the  subservicer for that
mortgage  loan  under  a  subservicing  agreement  between  Residential  Funding
Corporation  and the  subservicer  unless  servicing  is  released to the master
servicer or has been transferred to a servicer  approved by Residential  Funding
Corporation.  The master  servicer  may,  but is not  obligated  to,  assign the
related subservicing to designated  subservicers which will be qualified sellers
and  which  may  include  GMAC  Mortgage   Corporation  or  its  affiliates.   A
representative  form of subservicing  agreement is included as an exhibit to the
forms of pooling and servicing  agreements filed as exhibits to the registration
statement  of  which  this  prospectus  is a part.  The  subservicing  agreement
executed in connection with a Designated  Seller  Transaction or with respect to
some mortgage loans sold in negotiated  transactions  will usually vary from the
form filed herewith to accommodate the different  features of the mortgage loans
included  in  a  Designated  Seller  Transaction  and  to  vary  the  parameters
constituting  an event of  default.  The  following  description  describes  all
material  terms and  provisions  relating to the  subservicing  agreements.  The
description  does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, the form of  subservicing  agreement and by the
discretion of the master  servicer to modify the  subservicing  agreement and to
enter into different subservicing  agreements.  While any subservicing agreement
will be a contract solely between the master servicer and the  subservicer,  the
pooling and servicing  agreement  under which a series of certificates is issued
will  provide  that,  if for any reason the master  servicer  for that series of
certificates is no longer the master servicer of the related mortgage loans, the
trustee or any successor master servicer must recognize the subservicer's rights
and obligations under that subservicing agreement.

     With the approval of the master  servicer,  a subservicer  may delegate its
servicing obligations to third-party servicers, but that subservicer will remain
obligated under the related  subservicing  agreement.  Each  subservicer will be
required to perform the customary functions of a servicer, including:

      collection of payments from mortgagors and remittance of those collections
      to the master servicer;

      maintenance  of hazard  insurance  and  filing  and  settlement  of claims
      thereunder,  subject in some cases to the right of the master  servicer to
      approve in advance any such settlement;

      maintenance of escrow or impoundment accounts of mortgagors for payment of
      taxes,  insurance  and other items  required  to be paid by the  mortgagor
      under the mortgage loan;

      processing of assumptions or  substitutions,  although,  unless  otherwise
      specified in the related  prospectus  supplement,  the master  servicer is
      generally  required  to  exercise  due-on-sale  clauses to the extent such
      exercise is  permitted  by law and would not  adversely  affect  insurance
      coverage;

      attempting to cure delinquencies; and

      maintaining accounting records relating to the mortgage loans.

                                       18



<PAGE>



<PAGE>

     A subservicer  may also be required to supervise  foreclosures  and inspect
and manage  mortgaged  properties.  A subservicer will also be obligated to make
Advances to the master  servicer for  delinquent  installments  of principal and
interest,  net of any subservicing or other compensation,  on mortgage loans, as
described more fully under 'Description of the Certificates -- Advances,' and in
respect  of some  taxes and  insurance  premiums  not paid on a timely  basis by
mortgagors.  In  addition,  a  subservicer  is  obligated  to pay to the  master
servicer interest on the amount of any partial  prepayment of principal received
and applied to reduce the outstanding  principal balance of a mortgage loan from
the date of application of that payment to the first day of the following month.
Any amounts paid by a subservicer pursuant to the preceding sentence will be for
the benefit of the master  servicer as  additional  servicing  compensation.  No
assurance  can be given that the  subservicers  will carry out their  Advance or
payment  obligations  with respect to the mortgage loans. A subservicer  may, as
limited  by the  terms  of  the  related  prospectus  supplement,  transfer  its
servicing obligations to another entity that has been approved for participation
in Residential Funding  Corporation's loan purchase programs,  but only with the
approval of the master servicer.

     As compensation for its servicing duties,  the subservicer will be entitled
to a monthly  servicing fee, to the extent the related mortgage loan payment has
been  collected,  in a  minimum  amount  set  forth  in the  related  prospectus
supplement.  The  subservicer or master servicer may also be entitled to collect
and  retain,  as  part  of its  servicing  compensation,  any  late  charges  or
prepayment  penalties,  as provided in the mortgage note or related instruments.
The subservicer will be reimbursed by the master servicer for some  expenditures
which it makes,  in most cases to the same extent that the master servicer would
be reimbursed  under the  applicable  pooling and servicing  agreement.  In some
instances,  the subservicer will receive additional  compensation in the form of
all or a portion of the interest due and payable on the applicable mortgage loan
which is over and above the  interest  rate that the  depositor  or  Residential
Funding  Corporation,  as the case may be,  required at the time it committed to
purchase  the  mortgage  loan.  See 'The  Pooling  and  Servicing  Agreement  --
Servicing and Other Compensation and Payment of Expenses.'

     Each subservicer will be required to agree to indemnify the master servicer
for any liability or obligation  sustained by the master  servicer in connection
with any act or failure to act by the  subservicer  in its  servicing  capacity.
Each  subservicer  is  required  to  maintain a fidelity  bond and an errors and
omissions  policy with  respect to its  officers,  employees  and other  persons
acting on its behalf or on behalf of the master servicer.

     Each  subservicer  will be required to service each mortgage loan under the
terms of the  subservicing  agreement for the entire term of that mortgage loan,
unless the subservicing  agreement is earlier  terminated by the master servicer
or unless  servicing  is released to the master  servicer.  In  accordance  with
applicable  law, the master  servicer  may  terminate a  subservicing  agreement
immediately  upon the  giving  of  notice  upon  stated  events,  including  the
violation of the subservicing agreement by the subservicer,  or upon sixty days'
notice to the  subservicer  without  cause upon  payment  of an amount  equal to
approximately 2% of the aggregate  outstanding principal balance of all mortgage
loans,  including  the  mortgage  loans,  serviced by such  subservicer  under a
subservicing agreement.

     The master  servicer may agree with a subservicer  to amend a  subservicing
agreement. Upon termination of a subservicing agreement, the master servicer may
act as  servicer  of the  related  mortgage  loans or enter into one or more new
subservicing  agreements.  If the master servicer acts as servicer,  it will not
assume liability for the representations and warranties of the subservicer which
it replaces.  If the master servicer enters into a new  subservicing  agreement,
each new subservicer must either be a seller,  meet the standards for becoming a
seller or have servicing experience that is otherwise satisfactory to the master
servicer.

     The master servicer may make reasonable efforts to have the new subservicer
assume  liability  for the  representations  and  warranties  of the  terminated
subservicer,  but no assurance can be given that such an  assumption  will occur
and, in any event, if the new subservicer is an affiliate of Residential Funding
Corporation  the liability for such  representations  and warranties will not be
assumed by the new  subservicer.  In the event of this type of  assumption,  the
master  servicer  may in the  exercise  of its  business  judgment  release  the
terminated  subservicer  from  liability in respect of the  representations  and
warranties.  Any amendments to a subservicing agreement or to a new subservicing
agreement  may  contain  provisions  different  from  those  described  in  this
prospectus which are in effect in the original subservicing agreements. However,
the  pooling  and  servicing  agreement  for each  trust will  provide  that any
amendment or new agreement may not be  inconsistent  with or violate the related
pooling and servicing agreement in a manner which would materially and adversely
affect the interests of the certificateholders.

                        DESCRIPTION OF THE CERTIFICATES

GENERAL

     The certificates will be issued in series.  Each series of certificates or,
in some instances,  two or more series of  certificates,  will be issued under a
pooling and servicing agreement, similar to one of the forms filed as an exhibit
to the registration  statement under the Securities Act of 1933, as amended,  or
Securities  Act, with respect to the  certificates of which this prospectus is a
part. Each pooling and servicing agreement will be filed with the Securities and
Exchange  Commission  as an  exhibit  to a Form 8-K.  The  following  summaries,
together with additional  summaries under 'The Pooling and Servicing  Agreement'
below,  describe all material terms and provisions  relating to the certificates
common to each pooling and servicing agreement.  The summaries do not purport to
be complete and are subject to, and are qualified in their entirety by reference
to, all of the provisions of the pooling and servicing  agreement for each trust
and the related prospectus supplement.

     Each series of certificates  may consist of any one or a combination of the
following:

      a single class of certificates;

      two or more classes of senior  certificates,  of which one or more classes
      of  certificates  may be senior in right of payment to any other  class or
      classes of certificates subordinated thereto, and as to which some classes
      of senior or  subordinate  certificates  may be senior to other classes of
      senior  or  subordinate  certificates,  as  described  in  the  respective
      prospectus supplement;

      one or more  classes  of  mezzanine  certificates  which  are  subordinate
      certificates  but  which  are  senior  to  other  classes  of  subordinate
      certificates in respect of such distributions or losses;

      one or more  classes of strip  certificates  which will be entitled to (a)
      principal  distributions,  with  disproportionate,  nominal or no interest
      distributions  or  (b)  interest  distributions,   with  disproportionate,
      nominal or no principal distributions;

      two or  more  classes  of  certificates  which  differ  as to the  timing,
      sequential  order,  rate,  pass-through rate or amount of distributions of
      principal or interest or both, or as to which  distributions  of principal
      or  interest  or both on any  class  may be made  upon the  occurrence  of
      specified  events,  in  accordance  with a schedule or formula,  including
      'planned  amortization  classes' and 'targeted  amortization  classes' and
      'very accurately defined maturity classes,' or on the basis of collections
      from  designated  portions of the mortgage pool,  which series may include
      one or more  classes of accrual  certificates  with  respect to which some
      accrued interest will not be distributed but rather will be added to their
      principal balance on the distribution  date, which is the 25th day, or, if
      the 25th day is not a business  day, the next business day, of each month,
      commencing in the month  following the month in which the related  cut-off
      date occurs; or

      other types of classes of certificates, as described in the related
      prospectus supplement.

     Credit  support  for each  series of  certificates  will be  provided  by a
mortgage pool insurance  policy,  special hazard  insurance  policy,  bankruptcy
policy,  letter  of  credit,  purchase  obligation,  reserve  fund,  certificate
insurance  policy,  surety bond or other credit  enhancement as described  under
'Description  of Credit  Enhancement,'  or by the  subordination  of one or more
classes of certificates as described under 'Subordination' or by any combination
of the foregoing.

FORM OF CERTIFICATES

     As specified in the related prospectus supplement, the certificates of each
series will be issued either as physical  certificates or in book-entry form. If
issued as physical  certificates,  the certificates  will be in fully registered
form only in the denominations  specified in the related prospectus  supplement,
and will be transferable  and  exchangeable at the corporate trust office of the
certificate   registrar  appointed  under  the  related  pooling  and  servicing
agreement to register the  certificates.  No service charge will be made for any
registration  of  exchange  or  transfer  of  certificates,  but the trustee may
require  payment  of a sum  sufficient  to cover  any tax or other  governmental
charge.  The term  certificateholder  or holder  refers to the entity whose name
appears  on the  records  of the  certificate  registrar  or, if  applicable,  a
transfer agent, as the registered holder of the certificate, except as otherwise
indicated in the related prospectus supplement.

                                       20

     If issued in book-entry form, the classes of a series of certificates  will
be initially  issued through the book-entry  facilities of The Depository  Trust
Company,  or DTC, or CEDEL Bank, SA or the Euroclear  System (in Europe) if they
are participants of those systems, or indirectly through organizations which are
participants  in those systems,  or through any other  depositary or facility as
may be  specified  in the  related  prospectus  supplement.  As to any  class of
book-entry  certificates so issued, the record holder of those certificates will
be DTC's  nominee.  CEDEL  Bank,  SA and  Euroclear  System  will  hold  omnibus
positions on behalf of their participants through customers' securities accounts
in  CEDEL  Bank,  SA's  and  Euroclear  System's  names  on the  books  of their
respective  depositaries,  which in turn will hold those positions in customers'
securities  accounts in the  depositaries'  names on the books of DTC.  DTC is a
limited-purpose trust company organized under the laws of the State of New York,
which  holds  securities  for its DTC  participants,  which  include  securities
brokers and dealers,  banks,  trust  companies  and clearing  corporations.  DTC
together   with  the  CEDEL  Bank,  SA  and   Euroclear   System   participating
organizations   facilitates   the   clearance   and   settlement  of  securities
transactions between  participants through electronic  book-entry changes in the
accounts of  participants.  Other  institutions  that are not  participants  but
indirect  participants which clear through or maintain a custodial  relationship
with participants have indirect access to DTC's clearance system.

     Unless  otherwise  specified  in  the  related  prospectus  supplement,  no
beneficial  owner in an interest in any book-entry  certificate will be entitled
to receive a certificate representing that interest in registered,  certificated
form, unless either (i) DTC ceases to act as depository for that certificate and
a successor depository is not obtained, or (ii) the depositor elects in its sole
discretion to discontinue  the  registration  of the  certificates  through DTC.
Prior to any such event, beneficial owners will not be recognized by the trustee
or the master  servicer as holders of the related  certificates  for purposes of
the pooling  and  servicing  agreement,  and  beneficial  owners will be able to
exercise their rights as owners of their  certificates  only indirectly  through
DTC, participants and indirect  participants.  Any beneficial owner that desires
to purchase,  sell or otherwise transfer any interest in book-entry certificates
may do so only  through  DTC,  either  directly  if the  beneficial  owner  is a
participant or indirectly  through  participants  and, if  applicable,  indirect
participants.  Pursuant to the  procedures of DTC,  transfers of the  beneficial
ownership of any book-entry  certificates will be required to be made in minimum
denominations  specified in the related prospectus supplement.  The ability of a
beneficial owner to pledge  book-entry  certificates to persons or entities that
are not participants in the DTC system,  or to otherwise act with respect to the
certificates,  may be  limited  because  of the  lack of  physical  certificates
evidencing  the  certificates  and  because  DTC  may  act  only  on  behalf  of
participants.

     Because of time zone differences,  the securities  account of a CEDEL Bank,
SA or  Euroclear  System  participant  as a result of a  transaction  with a DTC
participant,  other than a  depositary  holding on behalf of CEDEL  Bank,  SA or
Euroclear  System,  will be credited during a subsequent  securities  settlement
processing  day,  which must be a business  day for CEDEL Bank,  SA or Euroclear
System,  as the case may be,  immediately  following  the DTC  settlement  date.
Credits or any transactions in those  securities  settled during this processing
will be reported to the relevant  Euroclear System participant or CEDEL Bank, SA
participants  on that business day. Cash received in CEDEL Bank, SA or Euroclear
System  as a result  of sales of  securities  by or  through  a CEDEL  Bank,  SA
participant or Euroclear System participant to a DTC participant, other than the
depositary for CEDEL Bank, SA or Euroclear  System,  will be received with value
on the DTC settlement date, but will be available in the relevant CEDEL Bank, SA
or  Euroclear  System  cash  account  only  as of  the  business  day  following
settlement in DTC.

     Transfers  between  participants  will occur in accordance  with DTC rules.
Transfers between CEDEL Bank, SA participants and Euroclear System  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 Bank, SA
participants or Euroclear System 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  depositaries;  however, the cross
market  transactions  will  require  delivery of  instructions  to the  relevant
European  international  clearing  system by the  counterparty in that 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 its
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.

                                       21

CEDEL Bank, SA participants  and Euroclear  System  participants may not deliver
instructions directly to the depositaries.

     CEDEL Bank,  SA, as a  professional  depository,  holds  securities for its
participating  organizations  and  facilitates  the clearance and  settlement of
securities  transactions  between CEDEL Bank, SA participants through electronic
book-entry  changes  in  accounts  of  CEDEL  Bank,  SA  participants,   thereby
eliminating the need for physical  movement of  certificates.  As a professional
depository,  CEDEL Bank, SA is subject to regulation by the Luxembourg  Monetary
Institute.

     Euroclear  System  was  created  to hold  securities  for  participants  of
Euroclear System and to clear and settle  transactions  between Euroclear System
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.  The
Euroclear  System  operator is the Brussels,  Belgium office of Morgan  Guaranty
Trust  Company  of New York,  under  contract  with the  clearance  cooperative,
Euroclear System Clearance Systems S.C., a Belgian co-operative corporation. All
operations  are conducted by the Euroclear  System  operator,  and all Euroclear
System  securities  clearance  accounts and  Euroclear  System cash accounts are
accounts with the Euroclear System operator, not the clearance cooperative.

     The clearance cooperative establishes policy for Euroclear System on behalf
of Euroclear System  participants.  The Euroclear System operator is the Belgian
branch of a New York banking  corporation  which is a member bank of the Federal
Reserve  System.  As a result,  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 the  Euroclear  System  operator are governed by
the terms and  conditions  Governing  Use of  Euroclear  System and the  related
operating  procedures of the Euroclear  System and  applicable  Belgian law. The
terms and conditions  govern  transfers of securities and cash within  Euroclear
System,  withdrawals of securities and cash from Euroclear System,  and receipts
of payments with respect to securities in Euroclear  System.  All  securities in
Euroclear  System are held on a fungible  basis without  attribution of specific
certificates to specific securities clearance accounts.

     Distributions  on the  book-entry  certificates  will be  forwarded  by the
trustee to DTC, and DTC will be  responsible  for  forwarding  those payments to
participants,  each of which will be responsible  for disbursing the payments to
the beneficial owners it represents or, if applicable, to indirect participants.
Accordingly,  beneficial owners may experience delays in the receipt of payments
in respect of their certificates.  Under DTC's procedures, DTC will take actions
permitted to be taken by holders of any class of book-entry  certificates  under
the  pooling  and  servicing  agreement  only  at the  direction  of one or more
participants to whose account the book-entry certificates are credited and whose
aggregate  holdings  represent  no less than any  minimum  amount of  percentage
interests or voting rights required therefor.  DTC may take conflicting  actions
with respect to any action of certificateholders of any class to the extent that
participants   authorize  those  actions.  None  of  the  master  servicer,  the
depositor,  the  trustee  or any of their  respective  affiliates  will have any
liability for any aspect of the records  relating to or payments made on account
of  beneficial  ownership  interests  in  the  book-entry  certificates,  or for
maintaining,  supervising or reviewing any records  relating to those beneficial
ownership interests.

ASSIGNMENT OF TRUST ASSETS

     At the time of issuance of a series of  certificates,  the  depositor  will
cause the  mortgage  loans or mortgage  securities  and any other  assets  being
included  in the related  trust to be  assigned  to the trustee or its  nominee,
which  may be  the  custodian,  together  with,  if  specified  in  the  related
prospectus supplement, all principal and interest received on or with respect to
the mortgage  loans or mortgage  securities  after the cut-off date,  other than
principal  and  interest  due on or before  the  cut-off  date and any  Excluded
Spread. The trustee will, concurrently with that assignment, deliver a series of
certificates  to the  depositor in exchange  for the mortgage  loans or mortgage
securities.  Each mortgage loan will be identified in a schedule appearing as an
exhibit to the related  pooling  and  servicing  agreement.  The  schedule  will
include,  among other things,  information  as to the principal  balance of each
mortgage  loan as of the cut-off  date, as well as  information  respecting  the
mortgage  rate,  the  currently  scheduled  monthly  payment  of  principal  and
interest,  the maturity of the mortgage note and the LTV ratio at origination or
modification, without regard to any secondary financing.

     If so specified in the related prospectus supplement, and in accordance
with the rules of membership of Merscorp, Inc. and/or Mortgage Electronic
Registration Systems, Inc. or, MERS, assignments of the mortgages

                                       22



<PAGE>



<PAGE>

for the mortgage  loans in the related trust will be  registered  electronically
through Mortgage Electronic  Registration Systems, Inc., or MERS'r' System. With
respect to mortgage  loans  registered  through the MERS'r'  System,  MERS shall
serve as mortgagee of record solely as a nominee in an  administrative  capacity
on  behalf  of the  trustee  and  shall  not have any  interest  in any of those
mortgage loans.

     In  addition,  the  depositor  will,  as to each  mortgage  loan other than
mortgage loans underlying any mortgage securities, deliver to the trustee, or to
the custodian,  a set of legal documents relating to each mortgage loan that are
in possession of the depositor, including:

      the mortgage note and any modification or amendment thereto endorsed
      without recourse either in blank or to the order of the trustee or its
      nominee;

      the  mortgage,  except  for any  mortgage  not  returned  from the  public
      recording office,  with evidence of recording indicated thereon or, in the
      case of a Cooperative Loan, on the related financing statement;

      an  assignment in  recordable  form of the mortgage,  or evidence that the
      mortgage  is held for the  trustee  through  the  MERS'r'  System or, with
      respect to a Cooperative  Loan,  an assignment of the related  proprietary
      lease or occupancy agreement; and

      if  applicable,  any  riders or  modifications  to the  mortgage  note and
      mortgage,  together with any other documents at such times as described in
      the related pooling and servicing agreement.

     The assignments may be blanket  assignments  covering  mortgages secured by
mortgaged   properties  located  in  the  same  county,  if  permitted  by  law.
Notwithstanding  the  foregoing,  a trust may include  mortgage  loans where the
original mortgage note is not delivered to the trustee if the depositor delivers
to the trustee or the  custodian a copy or a duplicate  original of the mortgage
note, together with an affidavit  certifying that the original mortgage note has
been lost or destroyed. With respect to those mortgage loans, the trustee or its
nominee  may not be able to  enforce  the  mortgage  note  against  the  related
borrower. Residential Funding Corporation will agree to repurchase or substitute
for that type of mortgage loan in some circumstances. See 'Mortgage Loan Program
- -- Representations by Sellers.'

     In the event that, with respect to any mortgage loan, the depositor  cannot
deliver the  mortgage or any  assignment  with  evidence  of  recording  thereon
concurrently  with  the  execution  and  delivery  of the  related  pooling  and
servicing  agreement  because of a delay caused by the public recording  office,
the  depositor  will  deliver  or cause to be  delivered  to the  trustee or the
custodian a true and  correct  photocopy  of the  mortgage  or  assignment.  The
depositor  will deliver or cause to be delivered to the trustee or the custodian
such mortgage or assignment with evidence of recording  indicated  thereon after
receipt  thereof  from  the  public   recording   office  or  from  the  related
subservicer.  Assignments  of the  mortgage  loans to the trustee or its nominee
will be recorded in the appropriate  public recording  office,  except in states
where,  in the opinion of counsel  acceptable  to the trustee,  recording is not
required to protect the  trustee's or nominee's  interests in the mortgage  loan
against the claim of any  subsequent  transferee or any successor to or creditor
of the depositor or the  originator of the mortgage loan, or except as otherwise
specified in the related prospectus supplement.

     With respect to any Puerto Rico mortgage loans,  the mortgages with respect
to those  mortgage  loans either a Direct  Puerto Rico Mortgage or an Endorsable
Puerto  Rico  Mortgage.  Endorsable  Puerto  Rico  Mortgages  do not  require an
assignment to transfer the related  lien.  Rather,  transfer of those  mortgages
follows an effective  endorsement of the related  mortgage note and,  therefore,
delivery of the  assignment  referred to in the third clause listed in the third
preceding  paragraph  would  be  inapplicable.  Direct  Puerto  Rico  Mortgages,
however,  require an  assignment  to be recorded with respect to any transfer of
the related lien and the  assignment  would be delivered to the trustee,  or the
custodian.

     Assignments  of the  mortgage  loans to the trustee will be recorded in the
appropriate public recording office, except for mortgages held under the MERS'r'
System or in states where, in the opinion of counsel  acceptable to the trustee,
the recording is not required to protect the trustee's interests in the mortgage
loan  against the claim of any  subsequent  transferee  or any  successor  to or
creditor of the depositor or the  originator of the mortgage  loan, or except as
otherwise specified in the related prospectus supplement.

REVIEW OF MORTGAGE LOANS

     The trustee or the custodian  will hold  documents in trust for the benefit
of the certificateholders, and within 45 days after receipt thereof, will review
such documents. If any such document is found to be defective in any

                                       23



<PAGE>



<PAGE>

material respect,  the trustee or the custodian shall promptly notify the master
servicer  and the  depositor,  the  former of which  shall  notify  the  related
subservicer or seller, as the case may be. If the subservicer or seller does not
cure the  omission or defect  within 60 days after notice is given to the master
servicer,  the  subservicer or seller,  as the case may be, will be obligated to
purchase  within  90 days of such  notice  the  related  mortgage  loan from the
trustee at its  purchase  price or,  except in the case of a  Designated  Seller
Transaction, substitute for such mortgage loan under the conditions specified in
the related  prospectus  supplement.  The master  servicer  will be obligated to
enforce this obligation of the subservicer or seller, as the case may be, to the
extent   described  in  this   prospectus   under   'Mortgage  Loan  Program  --
Representations  by Sellers' but in accordance with the provisions  described in
this prospectus under ' -- Realization Upon Defaulted Mortgage Loans.' There can
be no  assurance  that the  applicable  subservicer  or seller will  fulfill its
obligation to purchase any mortgage  loan.  Neither the master  servicer nor the
depositor will be obligated to purchase or substitute for a mortgage loan if the
subservicer or seller,  as the case may be, defaults on its obligation to do so.
This  purchase   obligation   constitutes  the  sole  remedy  available  to  the
certificateholders  or the trustee for omission  of, or a material  defect in, a
constituent  document.  Any mortgage  loan not so purchased or  substituted  for
shall remain in the related trust.

     The  trustee  will  be  authorized  at any  time  to  appoint  one or  more
custodians  under a custodial  agreement  to maintain  possession  of and review
documents  relating  to the  mortgage  loans as the  agent of the  trustee.  The
identity  of  any  custodian  will  be  set  forth  in  the  related  prospectus
supplement.

     With respect to the mortgage loans in a mortgage  pool,  except in the case
of a  Designated  Seller  Transaction  or as to mortgage  loans  underlying  any
mortgage  securities  or unless  otherwise  specified in the related  prospectus
supplement, the depositor will make limited representations and warranties as to
the types and  geographical  concentrations  of the mortgage loans and as to the
accuracy, in all material respects,  of some identifying  information in respect
of each such mortgage loan, for example,  original LTV ratio,  principal balance
as of the cut-off date, mortgage rate and maturity. Upon a breach of any of this
type of representation  which materially  adversely affects the interests of the
certificateholders  in a mortgage  loan, the depositor will be obligated to cure
the breach in all  material  respects,  to  purchase  the  mortgage  loan at its
purchase  price or to substitute  for the mortgage  loan a qualified  substitute
mortgage loan in accordance with the provisions for  substitution by Residential
Funding Corporation as described in this prospectus under 'Mortgage Loan Program
- -- Representations  by Sellers.' However,  the depositor will not be required to
repurchase or substitute for any mortgage loan in connection  with a breach of a
representation  and warranty if the  substance  of that breach also  constitutes
fraud  in the  origination  of the  related  mortgage  loan.  This  purchase  or
substitution    obligation    constitutes   the   sole   remedy   available   to
certificateholders or the trustee for a breach of this type of representation by
the  depositor.  Any mortgage  loan not so purchased  or  substituted  for shall
remain in the related trust.

     The master servicer will make  representations and warranties regarding its
authority to enter into, and its ability to perform its obligations  under,  the
pooling  and  servicing  agreement.  Upon  a  breach  of  any of  this  type  of
representation  of the master servicer which  materially  adversely  affects the
interests of the certificateholders in a mortgage loan, the master servicer will
be obligated  either to cure the breach in all material  respects or to purchase
the mortgage loan at its purchase price, less unreimbursed  Advances made by the
master  servicer with respect to the mortgage  loan,  or to  substitute  for the
mortgage  loan a  qualified  substitute  mortgage  loan in  accordance  with the
provisions for  substitution  described in this prospectus  under 'Mortgage Loan
Program -- Representations by Sellers.' This purchase or substitution obligation
will constitute the sole remedy available to  certificateholders  or the trustee
for a breach of this type of representation by the master servicer. Any mortgage
loan not so purchased or substituted for shall remain in the related trust.

     In accordance with the terms of each pooling and servicing  agreement,  the
master  servicer,  either  directly or through  subservicers,  will  service and
administer the mortgage loans assigned to the trustee.

SPREAD

     The depositor, the master servicer or any of their affiliates, or any other
entity  specified in the related  prospectus  supplement may retain or be paid a
portion of interest due with respect to the related  mortgage  loans or mortgage
securities.  The  payment of any  portion of  interest  in this  manner  will be
disclosed in the related prospectus supplement.  This payment may be in addition
to any other payment,  including a servicing  fee, that the specified  entity is
otherwise  entitled to receive with  respect to the  mortgage  loans or mortgage
securities.  Any  payment  of this  sort in  respect  of the  mortgage  loans or
mortgage securities will represent a specified

                                       24



<PAGE>



<PAGE>

portion  of the  interest  payable  thereon  and  as  specified  in the  related
prospectus  supplement,  will either be Excess  Spread or Excluded  Spread.  The
interest  portion  of a  Realized  Loss or  Extraordinary  Loss and any  partial
recovery  of interest in respect of the  mortgage  loans or mortgage  securities
will be allocated between the owners of any Excess Spread or Excluded Spread and
the  certificateholders  entitled  to  payments  of  interest as provided in the
applicable pooling and servicing agreement.

PAYMENTS ON MORTGAGE LOANS; DEPOSITS TO CERTIFICATE ACCOUNT

     Each subservicer  servicing a mortgage loan under a subservicing  agreement
will  establish  and  maintain  an  Subservicing  Account.  Except as  otherwise
permitted by the applicable nationally  recognized  statistical rating agency or
agencies maintaining a rating on the certificates of that series, a Subservicing
Account  must be  segregated  and may not be  established  as a  general  ledger
account,  and only  principal  and interest  payments and escrow  payments  from
mortgage loans serviced for Residential Funding Corporation may be held therein.

     A  subservicer  is required to deposit into its  Subservicing  Account on a
daily  basis all amounts  described  in this  prospectus  under  'Mortgage  Loan
Program --  Subservicing  by Sellers'  that are received by it in respect of the
mortgage loans, less its servicing or other compensation.  On or before the date
specified  in the  subservicing  agreement,  which date may be no later than the
business day prior to the determination  date referred to below and is currently
the 18th day of each month or, if that day is not a business  day, the preceding
business day, the  subservicer  must remit or cause to be remitted to the master
servicer  all funds held in the  Subservicing  Account  with respect to mortgage
loans that are required to be so remitted,  with the exception of prepayments in
full, some partial  prepayments and Liquidation  Proceeds which must be remitted
to the master servicer within five business days of receipt.  The subservicer is
also  required  to advance  on the  scheduled  date of  remittance  any  monthly
installment of principal and interest, less its servicing or other compensation,
on any  mortgage  loan for which  payment was not received  from the  mortgagor.
Unless otherwise specified in the related prospectus supplement, this obligation
of the subservicer to advance continues through the first of the month following
the date on which the related  mortgaged  property is sold at a foreclosure sale
or  is   acquired   by  the   trust  by  deed  in  lieu  of   foreclosure.   The
certificateholders  are  not  entitled  to  any  of  these  Advances  made  by a
subservicer.  Each  subservicer  may  also  be  required  to pay  to the  master
servicer,  for the master servicer's account,  interest, net of its servicing or
other  compensation,  on any partial  prepayment of principal  received during a
month and  applied by the  subservicer  prior to the first day of the  following
month,  from the date of  application  of the  payment  to the  first day of the
following month.

     The master  servicer  will deposit or will cause to be  deposited  into the
Custodial  Account  payments and  collections  received by it  subsequent to the
cut-off  date,  other  than  payments  due on or before  the  cut-off  date,  as
specifically  described in the related pooling and servicing  agreement,  which,
except as otherwise provided therein, generally will include the following:

      all payments on account of principal of the mortgage loans comprising a
      trust;

      all payments on account of interest on the mortgage loans  comprising that
      trust,  net of  the  portion  of  each  payment  thereof  retained  by the
      subservicer, if any, as its servicing or other compensation;

      liquidation proceeds;

      all amounts, net of unreimbursed liquidation expenses and insured expenses
      incurred,  and  unreimbursed  Servicing  Advances  made,  by  the  related
      subservicer,  received  and  retained,  including  Insurance  Proceeds  or
      proceeds from any alternative arrangements established in lieu of any such
      insurance and described in the  applicable  prospectus  supplement,  other
      than proceeds to be applied to the restoration of the related  property or
      released to the mortgagor in accordance with the master  servicer's normal
      servicing procedures;

      any  Buy-Down  Funds and,  if  applicable,  investment  earnings  thereon,
      required to be paid to certificateholders, as described in this prospectus
      under  'Description  of the  Certificates  -- Payments on Mortgage  Loans;
      Deposits to Certificate Account';

      all proceeds of any mortgage  loan in the trust  purchased or, in the case
      of a substitution,  amounts  representing a principal  adjustment,  by the
      master  servicer,  the depositor,  Residential  Funding  Corporation,  any
      subservicer  or seller or any other  person under the terms of the pooling
      and servicing agreement;

                                       25



<PAGE>



<PAGE>

      any amount  required to be deposited by the master  servicer in connection
      with  losses  realized  on  investments  of  funds  held in the  Custodial
      Account,  as  described  in  this  prospectus  under  'Description  of the
      Certificates  --  Payments  on Mortgage  Loans;  Deposits  to  Certificate
      Account'; and

      any amounts required to be transferred from the Certificate Account to the
      Custodial Account.

     See 'Mortgage Loan Program -- Representations by Sellers,' ' -- Assignment
of Mortgage Loans' above and 'Purchase Obligations.'

     In addition to the Custodial  Account,  the master  servicer will establish
and  maintain  the  Certificate  Account.  Both the  Custodial  Account  and the
Certificate Account must be either:

      maintained  with a depository  institution  whose debt  obligations at the
      time of any deposit  therein are rated by any rating agency that rated any
      certificates  of the  related  series  not  less  than a  specified  level
      comparable to the rating category of the certificates;

      an account or  accounts  the  deposits  in which are fully  insured to the
      limits established by the FDIC,  provided that any deposits not so insured
      shall be  otherwise  maintained  so that,  as  evidenced  by an opinion of
      counsel, the certificateholders  have a claim with respect to the funds in
      such  accounts  or a perfected  first  priority  security  interest in any
      collateral  securing  those  funds that is  superior  to the claims of any
      other depositors or creditors of the depository institution with which the
      accounts are maintained;

      in the  case  of the  Custodial  Account,  a  trust  account  or  accounts
      maintained in either the corporate trust department or the corporate asset
      services department of a financial  institution which has debt obligations
      that meet specified rating criteria;

      in the case of the Certificate Account, a trust account or accounts
      maintained with the trustee; or

      an Eligible Account.

     The collateral that is eligible to secure amounts in an Eligible Account is
limited to some Permitted  Investments.  A Certificate Account may be maintained
as an interest-bearing or a  non-interest-bearing  account, or funds therein may
be invested in  Permitted  Investments  as described  in this  prospectus  under
'Description  of the  Certificates  -- Payments on Mortgage  Loans;  Deposits to
Certificate  Account'.  The Custodial Account may contain funds relating to more
than one series of certificates  as well as payments  received on other mortgage
loans and assets  serviced or master  serviced by the master  servicer that have
been deposited into the Custodial Account.

     Unless otherwise described in the related prospectus supplement,  not later
than the business day preceding each distribution date, the master servicer will
withdraw from the Custodial Account and deposit into the applicable  Certificate
Account, in immediately  available funds, the amount to be distributed therefrom
to  certificateholders  on that  distribution  date. The master  servicer or the
trustee will also deposit or cause to be deposited into the Certificate Account:

      the amount of any Advances made by the master servicer as described herein
      under ' -- Advances;'

      any payments  under any letter of credit,  and any amounts  required to be
      transferred to the  Certificate  Account from a reserve fund, as described
      under 'Description of Credit Enhancement' below;

      any  amounts  required  to be paid by the master  servicer  out of its own
      funds due to the  operation of a deductible  clause in any blanket  policy
      maintained  by the master  servicer to cover hazard losses on the mortgage
      loans as described under 'Insurance Policies on Mortgage Loans' below;

      any distributions received on any mortgage securities included in the
      trust; and

      any other amounts as described in the related pooling and servicing
      agreement.

     The portion of any payment  received by the master servicer in respect of a
mortgage  loan  that is  allocable  to  Excess  Spread or  Excluded  Spread,  as
applicable,  will  typically be deposited  into the Custodial  Account,  but any
Excluded Spread will not be deposited in the Certificate Account for the related
series of  certificates  and will be  distributed  as  provided  in the  related
pooling and servicing agreement.

     Funds on deposit in the  Custodial  Account may be  invested  in  Permitted
Investments  maturing in general not later than the business day  preceding  the
next distribution date and funds on deposit in the related  Certificate  Account
may be invested in Permitted Investments maturing, in general, no later than the
distribution  date.  Except as  otherwise  specified  in the related  prospectus
supplement, all income and gain realized from any

                                       26

investment  will  be for  the  account  of the  master  servicer  as  additional
servicing  compensation.  The amount of any loss incurred in connection with any
such investment must be deposited in the Custodial Account or in the Certificate
Account,  as the case may be, by the master  servicer  out of its own funds upon
realization of the loss.

     With respect to each Buy-Down  Mortgage Loan, the subservicer  will deposit
the  related  Buy-Down  Funds  provided to it in a Buy-Down  Account  which will
comply with the  requirements  described  in this  prospectus  with respect to a
Subservicing  Account.  Unless  otherwise  specified  in the related  prospectus
supplement,   the  terms  of  all  Buy-Down   Mortgage  Loans  provide  for  the
contribution of Buy-Down Funds in an amount equal to or exceeding either (i) the
total  payments to be made from those funds  under the related  buydown  plan or
(ii) if the  Buy-Down  Funds are to be deposited  on a  discounted  basis,  that
amount of Buy-Down Funds which,  together with investment  earnings thereon at a
rate as set  forth in the  Client  Guide  from  time to time  will  support  the
scheduled level of payments due under the Buy-Down Mortgage Loan.

     Neither the master  servicer nor the depositor  will be obligated to add to
any discounted  Buy-Down Funds any of its own funds should  investment  earnings
prove  insufficient to maintain the scheduled  level of payments.  To the extent
that  any  insufficiency  is  not  recoverable  from  the  mortgagor  or,  in an
appropriate case, from the subservicer,  distributions to certificateholders may
be affected.  With respect to each Buy-Down  Mortgage Loan, the subservicer will
withdraw from the Buy-Down Account and remit to the master servicer on or before
the date specified in the  subservicing  agreement  described in this prospectus
under  'Description of the Certificates -- Payments on Mortgage Loans;  Deposits
to  Certificate  Account'  the amount,  if any, of the Buy-Down  Funds,  and, if
applicable,  investment earnings thereon,  for each Buy-Down Mortgage Loan that,
when added to the amount due from the mortgagor on the Buy-Down  Mortgage  Loan,
equals the full monthly payment which would be due on the Buy-Down Mortgage Loan
if it were not subject to the buydown plan.  The Buy-Down Funds will in no event
be a part of the related trust.

     If the  mortgagor on a Buy-Down  Mortgage Loan prepays the mortgage loan in
its entirety during the Buy-Down Period,  the subservicer will withdraw from the
Buy-Down  Account and remit to the  mortgagor or any other  designated  party in
accordance  with the related  buydown plan any Buy-Down  Funds  remaining in the
Buy-Down  Account.  If a prepayment  by a mortgagor  during the Buy-Down  Period
together  with  Buy-Down  Funds  will  result in full  prepayment  of a Buy-Down
Mortgage Loan, the subservicer will, in most cases, be required to withdraw from
the Buy-Down  Account and remit to the master  servicer  the Buy-Down  Funds and
investment  earnings  thereon,  if any, which together with such prepayment will
result  in a  prepayment  in  full;  provided  that  Buy-Down  Funds  may not be
available to cover a prepayment under some mortgage loan programs.  Any Buy-Down
Funds so  remitted  to the  master  servicer  in  connection  with a  prepayment
described  in the  preceding  sentence  will be deemed to reduce the amount that
would be  required  to be paid by the  mortgagor  to  repay  fully  the  related
mortgage loan if the mortgage loan were not subject to the buydown plan.

     Any investment  earnings remaining in the Buy-Down Account after prepayment
or after  termination  of the  Buy-Down  Period  will be remitted to the related
mortgagor  or any other  designated  party under the buydown  agreement.  If the
mortgagor  defaults  during  the  Buy-Down  Period  with  respect  to a Buy-Down
Mortgage Loan and the property  securing that Buy-Down  mortgage loan is sold in
liquidation either by the master servicer, the primary insurer, the pool insurer
under the mortgage pool insurance  policy or any other insurer,  the subservicer
will be required to withdraw  from the Buy-Down  Account the Buy-Down  Funds and
all  investment  earnings  thereon,  if any,  and remit  the same to the  master
servicer or, if instructed by the master  servicer,  pay the same to the primary
insurer or the pool insurer,  as the case may be, if the  mortgaged  property is
transferred  to that  insurer and the insurer  pays all of the loss  incurred in
respect of such default.

WITHDRAWALS FROM THE CUSTODIAL ACCOUNT

     The master  servicer  may,  from time to time,  make  withdrawals  from the
Custodial Account for certain purposes, as specifically described in the related
pooling and servicing  agreement,  which,  except as otherwise provided therein,
will include the following:

      to make  deposits  to the  Certificate  Account in the  amounts and in the
      manner  provided in the pooling and  servicing  agreement and described in
      this prospectus under 'Payments on Mortgage Loans; Deposits to Certificate
      Account;'

      to reimburse  itself or any  subservicer  for  Advances,  or for Servicing
      Advances,  out of late payments or  collections  on the mortgage loan with
      respect to which those Advances or Servicing Advances were made;

      to pay to itself or any subservicer unpaid Servicing Fees and Subservicing
      Fees, out of payments or collections of interest on each mortgage loan;

      to pay to itself  as  additional  servicing  compensation  any  investment
      income on funds deposited in the Custodial  Account,  any amounts remitted
      by subservicers as interest on partial  prepayments on the mortgage loans,
      and, if so provided in the pooling and  servicing  agreement,  any profits
      realized upon disposition of a mortgaged property acquired by deed in lieu
      of foreclosure or repossession or otherwise  allowed under the pooling and
      servicing agreement;

      to pay to itself,  a subservicer,  Residential  Funding  Corporation,  the
      depositor or the seller all amounts received with respect to each mortgage
      loan purchased,  repurchased or removed under the terms of the pooling and
      servicing  agreement and not required to be  distributed as of the date on
      which the related purchase price is determined;

      to pay the  depositor  or its  assignee,  or any other  party named in the
      related  prospectus  supplement,  all amounts  allocable  to the  Excluded
      Spread, if any, out of collections or payments which represent interest on
      each mortgage  loan,  including any mortgage loan as to which title to the
      underlying mortgaged property was acquired;

      to reimburse  itself or any  subservicer for any  Nonrecoverable  Advance,
      limited by the terms of the pooling and  servicing  agreement as described
      in the related prospectus supplement;

      to reimburse itself or the depositor for other expenses incurred for which
      it or the depositor is entitled to reimbursement,  including reimbursement
      in   connection   with   enforcing   any   repurchase,   substitution   or
      indemnification  obligation  of any  seller,  or  against  which it or the
      depositor is indemnified under the pooling and servicing agreement;

      to withdraw any amount deposited in the Custodial Account that was not
      required to be deposited therein; and

      to clear the Custodial  Account of amounts  relating to the  corresponding
      mortgage loans in connection  with the  termination of the trust under the
      pooling  and  servicing  agreement,  as  described  in  'The  Pooling  and
      Servicing Agreement -- Termination; Retirement of Certificates.'

DISTRIBUTIONS

     Beginning on the  distribution  date in the month next succeeding the month
in which the cut-off date  occurs,  or any other date as may be set forth in the
related  prospectus  supplement,  for a series of certificates,  distribution of
principal  and interest,  or, where  applicable,  of principal  only or interest
only, on each class of certificates  entitled thereto will be made either by the
trustee,  the master  servicer acting on behalf of the trustee or a paying agent
appointed by the trustee.  The distributions will be made to the persons who are
registered  as the holders of the  certificates  at the close of business on the
last business day of the preceding month.

     Distributions will be made in immediately available funds, by wire transfer
or otherwise,  to the account of a  certificateholder  at a bank or other entity
having appropriate facilities therefor, if the certificateholder has so notified
the trustee,  the master  servicer or the paying agent,  as the case may be, and
the  applicable  pooling  and  servicing  agreement  provides  for that  form of
payment,  or by check mailed to the address of the person entitled thereto as it
appears on the certificate register. Except as otherwise provided in the related
pooling and servicing  agreement,  the final  distribution  in retirement of the
certificates   will  be  made  only  upon  presentation  and  surrender  of  the
certificates  at the office or agency of the trustee  specified in the notice to
the certificateholders.  Distributions will be made to each certificateholder in
accordance with that holder's percentage interest in a particular class.

  Principal and Interest on the Certificates

     The method of determining,  and the amount of,  distributions  of principal
and interest,  or, where  applicable,  of principal  only or interest only, on a
particular series of certificates will be described in the related prospectus

                                       28

supplement. Distributions of interest on each class of certificates will be made
prior to distributions of principal thereon.  Each class of certificates,  other
than  classes of strip  certificates,  may have a different  specified  interest
rate,  or  pass-through  rate,  which  may be a fixed,  variable  or  adjustable
pass-through  rate, or any combination of two or more  pass-through  rates.  The
related  prospectus  supplement will specify the pass-through  rate or rates for
each  class,  or the  initial  pass-through  rate or rates  and the  method  for
determining the pass-through  rate or rates.  Unless otherwise  specified in the
related prospectus  supplement,  interest on the certificates will accrue during
each  calendar  month  and  will  be  payable  on the  distribution  date in the
following calendar month. If so specified in the related prospectus  supplement,
interest on any class of certificates for any  distribution  date may be limited
to the extent of available funds for that  distribution  date.  Unless otherwise
specified in the related  prospectus  supplement,  interest on the  certificates
will be  calculated  on the basis of a 360-day year  consisting of twelve 30-day
months.

     On each distribution date for a series of certificates,  the trustee or the
master  servicer on behalf of the trustee  will  distribute  or cause the paying
agent to  distribute,  as the case may be, to each  holder of record on the last
day of the preceding  month of a class of  certificates,  an amount equal to the
percentage  interest   represented  by  the  certificate  held  by  that  holder
multiplied by that class's Distribution Amount.

     In the case of a series of certificates  which includes two or more classes
of certificates,  the timing, sequential order, priority of payment or amount of
distributions  of  principal,  and any  schedule or formula or other  provisions
applicable to that determination, including distributions among multiple classes
of senior  certificates or subordinate  certificates,  shall be described in the
related  prospectus  supplement.  Distributions  of  principal  on any  class of
certificates  will be made on a pro rata basis among all of the  certificates of
that class unless otherwise set forth in the related prospectus supplement.

     Except  as  otherwise   provided  in  the  related  pooling  and  servicing
agreement,  on or prior to the 20th day,  or, if the 20th day is not a  business
day, the next business day, of the month of  distribution,  the master  servicer
will  determine  the  amounts of  principal  and  interest  which will be passed
through to certificateholders on the immediately  succeeding  distribution date.
Prior  to the  close of  business  on the  business  day  next  succeeding  each
determination  date, the master servicer will furnish a statement to the trustee
with  information  to be made  available  to  certificateholders  by the  master
servicer  on  request,  setting  forth,  among  other  things,  the amount to be
distributed on the next succeeding distribution date.

EXAMPLE OF DISTRIBUTIONS

     The following  chart sets forth an example of the flow of funds as it would
relate to a hypothetical series of certificates  issued, and with a cut-off date
occurring, in June 1999:

                                                and   interest  due  during  the
                                                related Due Period and  received

</TABLE>

Succeeding  months  follow  the  pattern of (B)  through  (G),  except  that for
succeeding  months,  (B) will also include the first day of that month. A series
of certificates may have different  prepayment  periods,  cut-off dates,  record
dates,  remittance dates,  determination  dates and/or  distribution  dates than
those set forth above.

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

 (A) The initial  principal  balance of the mortgage  pool will be the aggregate
     principal  balance of the mortgage loans at the close of business on June 1
     after  deducting  principal  payments  due on or before  that  date.  Those
     principal  payments due on or before June 1 and the  accompanying  interest
     payments, and any
                                              (footnotes continued on next page)

                                       29

(footnotes continued from previous page)
     Principal  Prepayments  received  as of the close of business on June 1 are
     not  part  of  the  mortgage  pool  and  will  not  be  passed  through  to
     certificateholders.

 (B) Any  Principal  Prepayments  may be received at any time during this period
     and will be remitted to the master  servicer as  described in (E) below for
     distribution  to  certificateholders  as  described  in (F)  below.  When a
     mortgage  loan is  prepaid  in full,  interest  on the  amount  prepaid  is
     collected from the mortgagor only to the date of payment. Partial Principal
     Prepayments  are  applied so as to reduce  the  principal  balances  of the
     related  mortgage  loans as of the  first  day of the  month  in which  the
     payments are made; no interest will be paid to certificateholders from such
     prepaid  amounts for the month in which the partial  Principal  Prepayments
     were received.

 (C) Distributions  on July 26 -- because July 25, 1999 is not a business day --
     will be made to  certificateholders  of record at the close of  business on
     June 30.

 (D) Scheduled principal and interest payments are due from mortgagors.

 (E) Payments  due  from  mortgagors  during  the  related  Due  Period  will be
     deposited  by  the  subservicers  in  Subservicing  Accounts,  or  will  be
     otherwise  managed  in a  manner  acceptable  to the  rating  agencies,  as
     received and will include the scheduled principal payments plus interest on
     the principal balances immediately prior to those payments.  Funds required
     to be remitted from the  Subservicing  Accounts to the master servicer will
     be  remitted on July 16 -- because  July 18, 1999 is not a business  day --
     together  with any  required  Advances  by the  subservicers,  except  that
     Principal Prepayments in full and Principal Prepayments in part received by
     subservicers  during the month of December  will have been  remitted to the
     master servicer within five business days of receipt.

 (F) On July 20, the master servicer will determine the amounts of principal and
     interest  which will be passed  through  on July 26 to the  holders of each
     class of certificates.  The master servicer will be obligated to distribute
     those  payments due during the related due period which have been  received
     from subservicers  prior to and including July 16, as well as all Principal
     Prepayments  received on mortgage loans in June, with interest  adjusted to
     the pass-through rates applicable to the respective classes of certificates
     and reduced on account of Principal  Prepayments as described in clause (B)
     above. Distributions to the holders of senior certificates, if any, on July
     26 may  include  amounts  otherwise  distributable  to the  holders  of the
     related subordinate  certificates,  amounts withdrawn from any reserve fund
     and  amounts  Advanced  by the  master  servicer  under  the  circumstances
     described in 'Subordination' and ' -- Advances.'

 (G) On July  26,  the  amounts  determined  on July 20 will be  distributed  to
     certificateholders.

     If provided in the related  prospectus  supplement,  the distribution  date
with  respect  to any  series of  certificates  as to which  the trust  includes
mortgage  securities may be a specified date or dates other than the 25th day of
each month in order to allow for the receipt of  distributions  on the  mortgage
securities.

ADVANCES

     As to each series of  certificates,  the master servicer will make Advances
on or before each  distribution  date,  but only to the extent that the Advances
would,  in the  judgment  of the master  servicer,  be  recoverable  out of late
payments  by  the  mortgagors,   Liquidation  Proceeds,  Insurance  Proceeds  or
otherwise.

     The amount of any Advance will be  determined  based on the amount  payable
under the mortgage  loan as adjusted from time to time and as may be modified as
described  in  this  prospectus  under  '  --  Collection  and  Other  Servicing
Practices,'  and no Advance will be required in connection with any reduction in
amounts payable under the Relief Act, or as a result of certain actions taken by
a  bankruptcy  court.  As specified in the related  prospectus  supplement  with
respect to any series of  certificates  as to which the trust includes  mortgage
securities,  the master servicer's advancing obligations will be pursuant to the
terms of the mortgage  securities,  as may be  supplemented  by the terms of the
applicable pooling and servicing  agreement,  and may differ from the provisions
relating to Advances described in this prospectus.

     Advances are intended to maintain a regular flow of scheduled  interest and
principal payments to related  certificateholders.  Advances do not represent an
obligation  of the master  servicer to guarantee or insure  against  losses.  If
Advances  have been made by the master  servicer from cash being held for future
distribution to

                                       30



<PAGE>



<PAGE>

certificateholders, those funds will be required to be replaced on or before any
future  distribution date to the extent that funds in the Certificate Account on
that  distribution  date  would be less  than  payments  required  to be made to
certificateholders. Any Advances will be reimbursable to the master servicer out
of  recoveries  on the  related  mortgage  loans for which  those  amounts  were
advanced,  including  late payments made by the related  mortgagor,  any related
Liquidation Proceeds and Insurance Proceeds,  proceeds of any applicable form of
credit enhancement, or proceeds of any mortgage loan purchased by the depositor,
Residential Funding Corporation, a subservicer or a seller.

     Advances may also be  reimbursable  from cash  otherwise  distributable  to
certificateholders  to the extent that the master  servicer shall determine that
any Advances previously made are not ultimately  recoverable as described in the
third preceding  paragraph.  With respect to any  senior/subordinate  series, so
long as the related subordinate certificates remain outstanding and limited with
respect  to  Special  Hazard  Losses,   Fraud  Losses,   Bankruptcy  Losses  and
Extraordinary  Losses,  the  Advances  may also be  reimbursable  out of amounts
otherwise distributable to holders of the subordinate certificates,  if any. The
master servicer may also be obligated to make Servicing Advances,  to the extent
recoverable out of Liquidation  Proceeds or otherwise,  in respect of some taxes
and  insurance  premiums  not paid by  mortgagors  on a timely  basis.  Funds so
advanced may be reimbursable  to the master servicer to the extent  permitted by
the pooling and  servicing  agreement.  Notwithstanding  the  foregoing,  if the
master servicer  exercises its option, if any, to purchase the assets of a trust
as  described  under  'The  Pooling  and  Servicing  Agreement  --  Termination;
Retirement of  Certificates'  below,  the master servicer will be deemed to have
been  reimbursed  for  all  related  Advances  previously  made  by it  and  not
theretofore reimbursed to it.

     The master  servicer's  obligation  to make  Advances  may be  supported by
another  entity,  a letter of credit or other  method as may be described in the
related  pooling and servicing  agreement.  In the event that the  short-term or
long-term  obligations of the provider of the support are downgraded by a rating
agency rating the related  certificates  or if any  collateral  supporting  such
obligation  is not  performing  or is removed  under the terms of any  agreement
described in the related  prospectus  supplement,  the  certificates may also be
downgraded.

PREPAYMENT INTEREST SHORTFALLS

     When a mortgagor  prepays a mortgage  loan in full  between  scheduled  due
dates for the mortgage  loan,  the mortgagor pays interest on the amount prepaid
only to but not including  the date on which the  Principal  Prepayment is made.
Similarly,  Liquidation  Proceeds  from a  mortgaged  property  will not include
interest for any period after the date on which the liquidation took place.

     If so specified in the related prospectus  supplement,  to the extent funds
are available from the Servicing Fee, the master servicer may make an additional
payment to certificateholders  with respect to any mortgage loan that prepaid in
full during the related prepayment period equal to the Compensating Interest for
that  mortgage  loan from the date of the  prepayment  to the  related due date.
Compensating  Interest will be limited to the aggregate  amount specified in the
related prospectus  supplement and may not be sufficient to cover the Prepayment
Interest  Shortfall.  If so  disclosed  in the  related  prospectus  supplement,
Prepayment  Interest  Shortfalls  may be  applied to reduce  interest  otherwise
payable  with respect to one or more classes of  certificates  of a series.  See
'Yield Considerations.'

REPORTS TO CERTIFICATEHOLDERS

     On each distribution  date, the master servicer will forward or cause to be
forwarded to each  certificateholder  of record a statement or  statements  with
respect to the related  trust  setting  forth the  information  described in the
related  pooling and servicing  agreement.  Except as otherwise  provided in the
related  pooling and  servicing  agreement,  the  information  will  include the
following (as applicable):

      the amount, if any, of the distribution allocable to principal;

      the amount, if any, of the distribution allocable to interest and the
      amount, if any, of any shortfall in the amount of interest and principal;

      the aggregate unpaid principal  balance of the mortgage loans after giving
      effect to the distribution of principal on that distribution date;

                                       31



<PAGE>



<PAGE>

      the  outstanding  principal  balance or  notional  amount of each class of
      certificates  after giving effect to the distribution of principal on that
      distribution date;

      based on the most recent reports furnished by subservicers, the number and
      aggregate  principal  balances of mortgage  loans in the related  mortgage
      pool that are  delinquent  (a) one  month,  (b) two  months  and (c) three
      months, and that are in foreclosure;

      the book value of any property acquired by the trust through foreclosure
      or grant of a deed in lieu of foreclosure;

      the balance of the reserve fund, if any, at the close of business on that
      distribution date;

      the  percentage  of the  outstanding  principal  balances  of  the  senior
      certificates,  if applicable,  after giving effect to the distributions on
      that distribution date;

      the amount of coverage under any letter of credit, mortgage pool insurance
      policy or other form of credit enhancement covering default risk as of the
      close of business on the applicable  determination  date and a description
      of any credit enhancement substituted therefor;

      if applicable, the Special Hazard Amount, Fraud Loss Amount and Bankruptcy
      Amount as of the close of business on the applicable distribution date and
      a description of any change in the calculation of those amounts;

      in  the  case  of  certificates   benefitting  from   alternative   credit
      enhancement arrangements described in a prospectus supplement,  the amount
      of coverage under the alternative arrangements as of the close of business
      on the applicable determination date;

      the servicing fee payable to the master servicer and the subservicer; and

      with respect to any series of  certificates as to which the trust includes
      mortgage  securities,  any  additional  information  as required under the
      related pooling and servicing agreement.

     In   addition   to   the   information    described   above,   reports   to
certificateholders  will  contain any other  information  as is described in the
applicable  pooling  and  servicing  agreement,   which  may  include,   without
limitation,  information as to Advances,  reimbursements to subservicers and the
master servicer and losses borne by the related trust.

     In addition,  to the extent  described in the related pooling and servicing
agreement,  within a  reasonable  period of time after the end of each  calendar
year, the master servicer will furnish a report to each person that was a holder
of record of any class of  certificates  at any time during that calendar  year.
The report will include  information  as to the  aggregate  of amounts  reported
pursuant to the first two items in the list above for that  calendar year or, in
the event the person was a holder of record of a class of certificates  during a
portion of that calendar year, for the applicable portion of that year.

COLLECTION AND OTHER SERVICING PROCEDURES

     The master servicer, directly or through subservicers,  as the case may be,
will make  reasonable  efforts  to  collect  all  payments  called for under the
mortgage  loans and will,  consistent  with the related  pooling  and  servicing
agreement  and any  applicable  insurance  policy or other  credit  enhancement,
follow the  collection  procedures as it follows with respect to mortgage  loans
serviced by it that are comparable to the mortgage  loans.  The master  servicer
may, in its  discretion,  waive any  prepayment  charge in  connection  with the
prepayment  of a  mortgage  loan or extend the due dates for  payments  due on a
mortgage note, provided that the insurance coverage for the mortgage loan or any
coverage  provided by any alternative  credit  enhancement will not be adversely
affected  thereby.  The master  servicer  may also waive or modify any term of a
mortgage loan so long as the master  servicer has determined  that the waiver or
modification is not materially  adverse to any  certificateholders,  taking into
account any estimated  loss that may result absent that action.  With respect to
any series of certificates as to which the trust includes  mortgage  securities,
the master servicer's servicing and administration  obligations will be pursuant
to the terms of those mortgage securities.

     Under its subservicing  agreement,  a subservicer is granted  discretion to
extend relief to mortgagors whose payments become delinquent.  A subservicer may
grant a period of temporary  indulgence,  in most cases up to three months, to a
mortgagor or may enter into a  liquidating  plan  providing for repayment by the
mortgagor of delinquent  amounts within six months from the date of execution of
the plan, in each case without the prior

                                       32

approval of the master servicer.  Most other types of forbearance require master
servicer approval. Neither indulgence nor forbearance with respect to a mortgage
loan  will  affect  the   pass-through   rate  or  rates  used  in   calculating
distributions to certificateholders. See ' -- Distributions.'

     In  instances  in which a  mortgage  loan is in  default  or if  default is
reasonably  foreseeable,  and if determined by the master  servicer to be in the
best interests of the related certificateholders, the master servicer may permit
modifications of the mortgage loan rather than proceeding with  foreclosure.  In
making this determination,  the estimated Realized Loss that might result if the
mortgage loan were liquidated would be taken into account.  These  modifications
may have the  effect  of  reducing  the  mortgage  rate or  extending  the final
maturity date of the mortgage loan. Any modified mortgage loan may remain in the
related trust, and the reduction in collections  resulting from the modification
may result in reduced  distributions of interest,  or other amounts,  on, or may
extend the final maturity of, one or more classes of the related certificates.

     In connection with any significant  partial  prepayment of a mortgage loan,
the  master  servicer,  to the  extent  not  inconsistent  with the terms of the
mortgage  note and local law and  practice,  may permit the mortgage  loan to be
re-amortized  so that the monthly payment is recalculated as an amount that will
fully  amortize its  remaining  principal  amount by the original  maturity date
based on the original mortgage rate, provided that the re-amortization shall not
be permitted  if it would  constitute a  modification  of the mortgage  loan for
federal income tax purposes.

     In any case in which property subject to a mortgage loan, other than an ARM
loan described  below, is being conveyed by the mortgagor,  the master servicer,
directly or through a subservicer,  shall in general be obligated, to the extent
it has knowledge of the  conveyance,  to exercise its rights to  accelerate  the
maturity of the mortgage loan under any due-on-sale  clause applicable  thereto,
but only if the exercise of those rights is permitted by applicable law and only
to the extent it would not  adversely  affect or jeopardize  coverage  under any
primary insurance policy or applicable credit enhancement  arrangements.  If the
master  servicer or  subservicer  is prevented  from  enforcing the  due-on-sale
clause under applicable law or if the master servicer or subservicer  determines
that it is  reasonably  likely that a legal  action would be  instituted  by the
related  mortgagor to avoid  enforcement of the due-on-sale  clause,  the master
servicer or subservicer will enter into an assumption and modification agreement
with  the  person  to whom  the  related  property  has  been or is  about to be
conveyed, under which that person becomes liable under the mortgage note subject
to specified  conditions.  The original mortgagor may be released from liability
on a mortgage loan if the master  servicer or subservicer  shall have determined
in good faith that the release will not adversely affect the  collectability  of
the mortgage loan.

     An ARM loan may be  assumed if the ARM loan is by its terms  assumable  and
if, in the reasonable  judgment of the master servicer or the  subservicer,  the
proposed transferee of the related mortgaged property establishes its ability to
repay the loan and the  security  for that ARM loan would not be impaired by the
assumption.  If a mortgagor  transfers the mortgaged  property subject to an ARM
loan without  consent,  the ARM loan may be declared  due and  payable.  Any fee
collected by the master  servicer or subservicer for entering into an assumption
or substitution  of liability  agreement will be retained by the master servicer
or subservicer as additional  servicing  compensation unless otherwise set forth
in the related  prospectus  supplement.  See 'Certain  Legal Aspects of Mortgage
Loans -- The Mortgage  Loans --  Enforceability  of Certain  Provisions' in this
prospectus.  In connection with any such assumption,  the mortgage rate borne by
the related mortgage note may not be altered.

     Mortgagors  may,  from  time  to  time,  request  partial  releases  of the
mortgaged properties,  easements, consents to alteration or demolition and other
similar matters. The master servicer or the related subservicer may approve this
type of  request  if it has  determined,  exercising  its  good  faith  business
judgment  in the same  manner  as it would if it were the  owner of the  related
mortgage loan, that approval will not adversely affect the security for, and the
timely and full  collectability of, the related mortgage loan. Any fee collected
by the master  servicer or the  subservicer  for processing this type of request
will be retained by the master  servicer or subservicer as additional  servicing
compensation.

     The master servicer will be required to maintain a fidelity bond and errors
and  omissions  policy with  respect to its  officers  and  employees  and other
persons  acting  on  behalf  of the  master  servicer  in  connection  with  its
activities under the pooling and servicing agreement.

SPECIAL SERVICING AND SPECIAL SERVICING AGREEMENTS

     The pooling and servicing agreement for a series of certificates may name a
Special  Servicer.  The Special Servicer may have discretion to extend relief to
certain mortgagors whose payments become delinquent. The Special Servicer may be
permitted to grant a period of temporary  indulgence to a mortgagor or may enter
into a repayment plan providing for repayment of arrearages by the mortgagor, in
each case without the prior approval of the master servicer or the  subservicer.
Other types of  forbearance  may require the approval of the master  servicer or
subservicer, as applicable.

     In addition,  the master  servicer may enter into various  agreements  with
holders of one or more  classes  of  subordinate  certificates  or of a class of
securities  representing  interests  in  one  or  more  classes  of  subordinate
certificates.  Under the terms of those agreements, the holder may, with respect
to some delinquent mortgage loans:

      instruct the master servicer to commence or delay foreclosure proceedings,
      provided  that the  holder  deposits a  specified  amount of cash with the
      master   servicer   which   will  be   available   for   distribution   to
      certificateholders  in the event that  Liquidation  Proceeds are less than
      they  otherwise  may have been had the  master  servicer  acted  under its
      normal servicing procedures;

      instruct the master servicer to purchase the mortgage loans from the trust
      prior to the commencement of foreclosure proceedings at the purchase price
      and to  resell  the  mortgage  loans  to the  holder,  in  which  case any
      subsequent  loss with respect to the mortgage  loans will not be allocated
      to the certificateholders;

      become,  or designate a third party to become,  a subservicer with respect
      to the mortgage loans so long as (i) the master  servicer has the right to
      transfer the subservicing  rights and obligations of the mortgage loans to
      another  subservicer  at any  time or (ii)  the  holder  or its  servicing
      designee is required to service the mortgage loans according to the master
      servicer's servicing guidelines; or

      the related prospectus supplement may provide for the other types of
      special servicing arrangements.

REALIZATION UPON DEFAULTED MORTGAGE LOANS

     In the event that title to any acquisition of title and cancellation of any
REO Mortgage  Loan will be  considered  for most  purposes to be an  outstanding
mortgage loan held in the trust until it is converted into a Liquidated Mortgage
Loan.

     For purposes of calculations of amounts distributable to certificateholders
in respect of an REO Mortgage Loan, the  amortization  schedule in effect at the
time of any acquisition of title, before any adjustment thereto by reason of any
bankruptcy  or any similar  proceeding or any  moratorium  or similar  waiver or
grace period,  will be deemed to have continued in effect and, in the case of an
ARM  Loan,  the  amortization  schedule  will  be  deemed  to have  adjusted  in
accordance  with any interest  rate changes  occurring  on any  adjustment  date
therefor, so long as the REO Mortgage Loan is considered to remain in the trust.
If a REMIC  election has been made,  any  mortgaged  property so acquired by the
trust must be disposed  of in  accordance  with  applicable  federal  income tax
regulations  and  consistent  with the  status of the  trust as a REMIC.  To the
extent provided in the related pooling and servicing agreement,  any income, net
of expenses and other than gains described in the second  succeeding  paragraph,
received by the  subservicer  or the master  servicer on the mortgaged  property
prior to its disposition will be deposited in the Custodial Account upon receipt
and will be available at that time to the extent provided in the related pooling
and servicing agreement, for making payments to certificateholders.

     With respect to a mortgage loan in default,  the master servicer may pursue
foreclosure  or similar  remedies  concurrently  with  pursuing any remedy for a
breach of a  representation  and warranty.  However,  the master servicer is not
required to continue to pursue both remedies if it determines that one remedy is
more  likely  to  result  in a  greater  recovery.  If the  mortgage  loan is an
Additional  Collateral Loan, the master servicer or the related subservicer,  if
the lien on the Additional Collateral for such Additional Collateral Loan is not
assigned to the trustee on behalf of the certificateholders, may proceed against
the related mortgaged property or the related Additional Collateral first or may
proceed against both concurrently,  as permitted by applicable law and the terms
under  which  the  Additional  Collateral  is held,  including  any  third-party
guarantee.

     Upon  the  first  to  occur  of  final  liquidation  and  a  repurchase  or
substitution pursuant to a breach of a representation and warranty, the mortgage
loan will be removed from the related trust. The master servicer may

                                       34



<PAGE>



<PAGE>

elect to treat a defaulted  mortgage  loan as having been finally  liquidated if
substantially  all amounts expected to be received in connection  therewith have
been received. Any additional liquidation expenses relating to the mortgage loan
thereafter  incurred  will  be  reimbursable  to  the  master  servicer  or  any
subservicer   from  any   amounts   otherwise   distributable   to  the  related
certificateholders,  or may be offset by any subsequent  recovery related to the
mortgage loan. Alternatively,  for purposes of determining the amount of related
Liquidation Proceeds to be distributed to certificateholders,  the amount of any
Realized Loss or the amount  required to be drawn under any  applicable  form of
credit enhancement, the master servicer may take into account minimal amounts of
additional  receipts  expected to be received,  as well as estimated  additional
liquidation  expenses  expected to be incurred in connection  with the defaulted
mortgage loan.

     With respect to some series of certificates,  the applicable form of credit
enhancement may provide,  to the extent of coverage,  that a defaulted  mortgage
loan or REO  Mortgage  Loan will be  removed  from the trust  prior to its final
liquidation.  If a final  liquidation  of a mortgage loan resulted in a Realized
Loss and within two years  thereafter the master servicer  receives a subsequent
recovery  specifically  related to that  mortgage  loan,  in  connection  with a
related breach of a  representation  or warranty or otherwise,  such  subsequent
recovery  shall be  distributed to the  then-current  certificateholders  of any
outstanding class to which the Realized Loss was allocated,  with the amounts to
be  distributed  allocated  among such classes in the same  proportions  as such
Realized Loss was allocated,  provided that no such  distributions of subsequent
recoveries,  together  with any other  reimbursement  amounts,  exceed the total
amount of the Realized Loss that was allocated to that class.  In the event that
any class of certificates to which such Realized Loss was allocated is no longer
outstanding,  any  subsequent  recovery  shall be distributed to the persons who
were the holders of that class of certificates when it was retired.  In the case
of a series  of  certificates  other  than a  senior/subordinate  series,  if so
provided in the related  prospectus  supplement,  the applicable  form of credit
enhancement  may  provide  for   reinstatement   in  accordance  with  specified
conditions in the event that, following the final liquidation of a mortgage loan
and a draw under the  related  credit  enhancement,  subsequent  recoveries  are
received.  If a defaulted  mortgage  loan or REO Mortgage Loan is not so removed
from the trust, then, upon its final liquidation, if a loss is realized which is
not covered by any applicable form of credit enhancement or other insurance, the
certificateholders will bear the loss. However, if a gain results from the final
liquidation  of an REO Mortgage Loan which is not required by law to be remitted
to the related  mortgagor,  the master  servicer will be entitled to retain that
gain  as  additional  servicing   compensation  unless  the  related  prospectus
supplement  provides  otherwise.  For a  description  of the  master  servicer's
obligations  to  maintain  and make  claims  under  applicable  forms of  credit
enhancement and insurance  relating to the mortgage loans,  see  'Description of
Credit Enhancement' and 'Insurance Policies on Mortgage Loans.'

     For a  discussion  of legal  rights  and  limitations  associated  with the
foreclosure of a mortgage loan, see 'Certain Legal Aspects of Mortgage Loans.'

                                 SUBORDINATION

GENERAL

     A  senior/subordinate  series of  certificates  will consist of one or more
classes  of  senior   certificates  and  one  or  more  classes  of  subordinate
certificates,  as specified in the related prospectus supplement.  Subordination
of  the  subordinate  certificates  of any  senior/subordinate  series  will  be
effected by the following method,  unless an alternative  method is specified in
the  related  prospectus  supplement.  In  addition,  some  classes of senior or
subordinate certificates may be senior to other classes of senior or subordinate
certificates, as specified in the related prospectus supplement.

     With respect to any  senior/subordinate  series, the total amount available
for distribution on each distribution date, as well as the method for allocating
that amount among the various  classes of  certificates  included in the series,
will be described in the related prospectus supplement.  Generally, with respect
to any series,  the amount available for distribution will be allocated first to
interest on the senior certificates of that series, and then to principal of the
senior  certificates  up to the  amounts  described  in the  related  prospectus
supplement, prior to allocation of any amounts to the subordinate certificates.

     If so provided in the pooling and servicing agreement,  the master servicer
may be  permitted,  under certain  circumstances,  to purchase any mortgage loan
that is three or more months  delinquent  in payments of principal and interest,
at the purchase  price.  Any Realized Loss  subsequently  incurred in connection
with any such

                                       35



<PAGE>



<PAGE>

mortgage loan will be borne by the then-current  certificateholders of the class
or classes that would have borne that Realized Loss if the mortgage loan had not
been so purchased,  unless that purchase was made upon the request of the holder
of the most junior class of certificates of the related series.

     In the  event of any  Realized  Losses  not in  excess  of the  limitations
described below, other than Extraordinary  Losses, the rights of the subordinate
certificateholders to receive distributions will be subordinate to the rights of
the  senior  certificateholders  and the owner of the  Excess  Spread  and as to
certain classes of subordinate certificates, may be subordinate to the rights of
other subordinate certificateholders.

     Except as noted below, Realized Losses will be allocated to the subordinate
certificates of the related series until their  outstanding  principal  balances
have been reduced to zero. Additional Realized Losses, if any, will be allocated
to the senior certificates. If the series includes more than one class of senior
certificates,  the additional  Realized Losses will be allocated either on a pro
rata  basis  among  all  of the  senior  certificates  in  proportion  to  their
respective  outstanding  principal  balances  or as  otherwise  provided  in the
related prospectus supplement.

     Special  Hazard  Losses in  excess of the  Special  Hazard  Amount  will be
allocated among all  outstanding  classes of certificates of the related series,
either  on a pro  rata  basis  in  proportion  to  their  outstanding  principal
balances,  or as otherwise  provided in the related prospectus  supplement.  The
respective  amounts of other specified  types of losses,  including Fraud Losses
and Bankruptcy Losses, that may be borne solely by the subordinate  certificates
may be  similarly  limited  to the Fraud  Loss  Amount  and with  respect to the
Bankruptcy Amount, and the subordinate certificates may provide no coverage with
respect  to other  specified  types  of  losses,  as  described  in the  related
prospectus  supplement,  in which case those  losses would be allocated on a pro
rata  basis  among all  outstanding  classes  of  certificates  or as  otherwise
specified  in the related  prospectus  supplement.  Each of the  Special  Hazard
Amount,  Fraud Loss  Amount  and  Bankruptcy  Amount may be subject to  periodic
reductions and may be subject to further  reduction or termination,  without the
consent  of the  certificateholders,  upon the  written  confirmation  from each
applicable  rating agency,  as described in the related  prospectus  supplement,
that the then-current  rating of the related series of certificates  will not be
adversely affected.

     In most  cases,  any  allocation  of a Realized  Loss,  including a Special
Hazard Loss, to a  certificate  in a  senior/subordinate  series will be made by
reducing its outstanding principal balance as of the distribution date following
the calendar month in which the Realized Loss was incurred.

     The rights of holders of the various  classes of certificates of any series
to  receive  distributions  of  principal  and  interest  is  determined  by the
aggregate  outstanding  principal  balance of each class or, if applicable,  the
related notional amount.  The outstanding  principal  balance of any certificate
will be  reduced  by all  amounts  previously  distributed  on that  certificate
representing  principal,  and by any Realized Losses allocated thereto. If there
are no Realized  Losses or Principal  Prepayments on any of the mortgage  loans,
the  respective  rights of the holders of  certificates  of any series to future
distributions  generally would not change.  However,  to the extent described in
the  related  prospectus  supplement,  holders  of  senior  certificates  may be
entitled to receive a  disproportionately  larger amount of prepayments received
during specified periods,  which will have the effect, absent offsetting losses,
of accelerating the  amortization of the senior  certificates and increasing the
respective   percentage   ownership   interest   evidenced  by  the  subordinate
certificates  in  the  related  trust,  with  a  corresponding  decrease  in the
percentage of the  outstanding  principal  balances of the senior  certificates,
thereby  preserving  the  availability  of  the  subordination  provided  by the
subordinate  certificates.  In addition,  some Realized Losses will be allocated
first to subordinate  certificates by reduction of their  outstanding  principal
balance,  which  will have the effect of  increasing  the  respective  ownership
interest evidenced by the senior certificates in the related trust.

     If so provided in the related prospectus supplement, some amounts otherwise
payable on any  distribution  date to holders of  certificates  may be deposited
into a  reserve  fund.  Amounts  held in any  reserve  fund  may be  applied  as
described under  'Description of Credit Enhancement -- Reserve Funds' and in the
related prospectus supplement.

     In lieu of the foregoing  provisions,  subordination may be effected in the
following  manner,  or in any other  manner as may be  described  in the related
prospectus supplement.  The rights of the holders of subordinate certificates to
receive the  Subordinate  Amount will be limited to the extent  described in the
related   prospectus   supplement.   As  specified  in  the  related  prospectus
supplement,  the  Subordinate  Amount  may be  reduced  based upon the amount of
losses borne by the holders of the  subordinate  certificates as a result of the
subordination,  a  specified  schedule  or  other  method  of  reduction  as the
prospectus supplement may specify.

                                       36



<PAGE>



<PAGE>

     With respect to any senior/subordinate  series, the terms and provisions of
the  subordination  may  vary  from  those  described  in this  prospectus.  Any
variation and any additional credit enhancement will be described in the related
prospectus supplement.

OVERCOLLATERALIZATION

     If so specified in the related prospectus supplement,  interest collections
on the mortgage loans may exceed interest  payments on the  certificates for the
related  distribution  date.  To the extent such  excess  interest is applied as
principal  payments  on the  certificates,  the  effect  will be to  reduce  the
principal balance of the certificates relative to the outstanding balance of the
mortgage loans, thereby creating overcollateralization and additional protection
to the certificateholders, as specified in the related prospectus supplement.

                       DESCRIPTION OF CREDIT ENHANCEMENT

GENERAL

     Credit support with respect to each series of certificates may be comprised
of one or more of the following  components.  Each  component will have a dollar
limit and will provide coverage with respect to Realized Losses that are:

      Defaulted Mortgage Losses;

      Special Hazard Losses;

      Bankruptcy Losses; and

      Fraud Losses.

     Most forms of credit support will not provide  protection against all risks
of loss and will not  guarantee  repayment of the entire  outstanding  principal
balance of the  certificates and interest  thereon.  If losses occur that exceed
the amount covered by credit support or are of a type that is not covered by the
credit   support,   certificateholders   will  bear  their  allocable  share  of
deficiencies.  In particular,  Defaulted Mortgage Losses, Special Hazard Losses,
Bankruptcy  Losses and Fraud Losses in excess of the amount of coverage provided
therefor and  Extraordinary  Losses will not be covered.  To the extent that the
credit   enhancement  for  any  series  of   certificates   is  exhausted,   the
certificateholders  will bear all further  risks of loss not  otherwise  insured
against.

     As described in this prospectus and in the related prospectus supplement,

      coverage with respect to Defaulted Mortgage Losses may be provided by a
      mortgage pool insurance policy,

      coverage with respect to Special Hazard Losses may be provided by a
      special hazard insurance policy,

      coverage with respect to Bankruptcy Losses may be provided by a bankruptcy
      policy and

      coverage  with respect to Fraud Losses may be provided by a mortgage  pool
      insurance policy or mortgage repurchase bond.

In addition, if so specified in the applicable prospectus supplement, in lieu of
or in addition to any or all of the foregoing  arrangements,  credit enhancement
may be in the form of a  reserve  fund to  cover  those  losses,  in the form of
subordination  of one  or  more  classes  of  certificates  as  described  under
'Subordination,'  or in the form of a certificate  insurance policy, a letter of
credit,  mortgage  pool  insurance  policies,  surety  bonds or  other  types of
insurance policies,  other secured or unsecured  corporate  guarantees or in any
other form as may be described in the related prospectus  supplement,  or in the
form of a combination of two or more of the foregoing.

     In addition,  the credit  support may be provided by an  assignment  of the
right to receive  cash  amounts,  a deposit of cash into a reserve fund or other
pledged assets, or by banks, insurance companies,  guarantees or any combination
thereof  identified in the related prospectus  supplement.  Coverage may also be
provided by  representations  made by  Residential  Funding  Corporation  or the
depositor. If so specified in the related prospectus supplement,  limited credit
enhancement may be provided to cover  Defaulted  Mortgage Losses with respect to
mortgage  loans with LTV ratios at origination of over 80% which are not insured
by a primary  insurance policy, to the extent that those losses would be covered
under a primary  insurance  policy if  obtained,  or may be  provided in lieu of
title insurance coverage,  in the form of a corporate guaranty or in other forms
described in this section. Credit support may also be provided in the form of an
insurance policy covering the

                                       37



<PAGE>



<PAGE>

risk of  collection  and  adequacy  of any  Additional  Collateral  provided  in
connection  with any  Additional  Collateral  Loan, as limited by such insurance
policy. As described in the pooling and servicing agreement,  credit support may
apply to all of the  mortgage  loans or to some  mortgage  loans  contained in a
mortgage pool.

     Each prospectus supplement will include a description of:

      the amount payable under the credit enhancement arrangement, if any,
      provided with respect to a series;

      any conditions to payment thereunder not otherwise described in this
      prospectus;

      the conditions under which the amount payable under the credit support may
      be  reduced  and under  which the  credit  support  may be  terminated  or
      replaced; and

      the material provisions of any agreement relating to the credit support.

     Additionally,  each  prospectus  supplement will contain  information  with
respect to the issuer of any third-party credit enhancement,  if applicable. The
pooling and servicing agreement or other documents may be modified in connection
with the  provisions  of any  credit  enhancement  arrangement  to  provide  for
reimbursement rights, control rights or other provisions that may be required by
the credit  enhancer.  To the extent  provided  in the  applicable  pooling  and
servicing  agreement,  the credit  enhancement  arrangements may be periodically
modified,  reduced and  substituted  for based on the  performance  of or on the
aggregate  outstanding  principal balance of the mortgage loans covered thereby.
See  'Description  of Credit  Enhancement -- Reduction or Substitution of Credit
Enhancement.'  If  specified in the  applicable  prospectus  supplement,  credit
support  for a series of  certificates  may cover  one or more  other  series of
certificates.

     The  descriptions  of any insurance  policies,  bonds or other  instruments
described  in this  prospectus  or any  prospectus  supplement  and the coverage
thereunder do not purport to be complete and are qualified in their  entirety by
reference to the actual forms of the policies, copies of which generally will be
exhibits to the Form 8-K to be filed with the Securities and Exchange Commission
in connection with the issuance of the related series of certificates.

LETTERS OF CREDIT

     If any component of credit  enhancement as to any series of certificates is
to be  provided  by a letter of credit,  a bank will  deliver to the  trustee an
irrevocable  letter of credit.  The letter of credit may provide direct coverage
with  respect  to the  mortgage  loans.  The letter of credit  bank,  the amount
available  under the letter of credit with  respect to each  component of credit
enhancement,  the expiration  date of the letter of credit,  and a more detailed
description of the letter of credit will be specified in the related  prospectus
supplement.  On or before each distribution date, the letter of credit bank will
be  required  to make  payments  after  notification  from  the  trustee,  to be
deposited  in the  related  Certificate  Account  with  respect to the  coverage
provided  thereby.  The letter of credit  may also  provide  for the  payment of
Advances.

MORTGAGE POOL INSURANCE POLICIES

     Any insurance  policy  covering losses on a pool of mortgage loans obtained
by the depositor  for a trust will be issued by the pool insurer.  Each mortgage
pool insurance  policy,  in accordance  with the  limitations  described in this
prospectus  and in the  prospectus  supplement,  if any,  will  cover  Defaulted
Mortgage  Losses in an amount equal to a percentage  specified in the applicable
prospectus  supplement of the aggregate  principal balance of the mortgage loans
on the cut-off date. As described under ' -- Maintenance of Credit Enhancement,'
the  master  servicer  will use its best  reasonable  efforts  to  maintain  the
mortgage  pool  insurance  policy and to present  claims  thereunder to the pool
insurer  on  behalf of  itself,  the  trustee  and the  certificateholders.  The
mortgage pool insurance  policies,  however,  are not blanket  policies  against
loss, since claims thereunder may only be made respecting  particular  defaulted
mortgage  loans and only upon  satisfaction  of specified  conditions  precedent
described  in  the  succeeding  paragraph.   Unless  specified  in  the  related
prospectus supplement, the mortgage pool insurance policies may not cover losses
due to a failure to pay or denial of a claim under a primary  insurance  policy,
irrespective of the reason therefor.

                                       38



<PAGE>



<PAGE>

     Each  mortgage  pool  insurance  policy will  provide that no claims may be
validly presented thereunder unless, among other things:

      any required primary insurance policy is in effect for the defaulted
      mortgage loan and a claim thereunder has been submitted and settled;

      hazard insurance on the property  securing the mortgage loan has been kept
      in force  and real  estate  taxes and other  protection  and  preservation
      expenses have been paid by the master servicer;

      if there has been physical loss or damage to the  mortgaged  property,  it
      has been restored to its condition,  reasonable wear and tear excepted, at
      the cut-off date; and

      the insured has  acquired  good and  merchantable  title to the  mortgaged
      property free and clear of liens except permitted encumbrances.

     Upon  satisfaction  of these  conditions,  the pool  insurer  will have the
option either (a) to purchase the property securing the defaulted  mortgage loan
at a price equal to its  outstanding  principal  balance plus accrued and unpaid
interest  at the  applicable  mortgage  rate to the  date of  purchase  and some
expenses incurred by the master servicer or subservicer on behalf of the trustee
and  certificateholders,  or (b) to pay  the  amount  by  which  the  sum of the
outstanding  principal  balance of the defaulted  mortgage loan plus accrued and
unpaid interest at the mortgage rate to the date of payment of the claim and the
aforementioned  expenses exceeds the proceeds  received from an approved sale of
the  mortgaged  property,  in either case net of some amounts paid or assumed to
have been paid under any related primary insurance policy.

     Certificateholders  will  experience  a shortfall in the amount of interest
payable on the related  certificates  in  connection  with the payment of claims
under a mortgage pool insurance policy because the pool insurer is only required
to remit  unpaid  interest  through the date a claim is paid rather than through
the  end  of  the  month  in  which  the  claim  is  paid.   In  addition,   the
certificateholders  will also  experience  losses  with  respect to the  related
certificates  in connection  with payments made under a mortgage pool  insurance
policy to the extent that the master servicer expends funds to cover unpaid real
estate  taxes or to repair the  related  mortgaged  property  in order to make a
claim under a mortgage  pool  insurance  policy,  as those  amounts  will not be
covered by  payments  under the policy  and will be  reimbursable  to the master
servicer  from  funds  otherwise  payable  to  the  certificateholders.  If  any
mortgaged  property securing a defaulted  mortgage loan is damaged and proceeds,
if any (see ' -- Special Hazard  Insurance  Policies'  below for risks which are
not covered by those  policies),  from the related  hazard  insurance  policy or
applicable  special  hazard  insurance  policy are  insufficient  to restore the
damaged property to a condition sufficient to permit recovery under the mortgage
pool  insurance  policy,  the master  servicer is not required to expend its own
funds to restore the damaged  property unless it determines that (a) restoration
will  increase  the  proceeds to one or more  classes of  certificateholders  on
liquidation of the mortgage loan after  reimbursement of the master servicer for
its expenses and (b) the expenses will be recoverable by it through  Liquidation
Proceeds or Insurance Proceeds.

     A mortgage pool insurance policy and some primary  insurance  policies will
likely not insure  against loss  sustained by reason of a default  arising from,
among other things,  fraud or negligence  in the  origination  or servicing of a
mortgage loan, including misrepresentation by the mortgagor, the seller or other
persons  involved in the origination  thereof,  failure to construct a mortgaged
property in accordance with plans and  specifications  or bankruptcy,  except if
specified in the related  prospectus  supplement an  endorsement to the mortgage
pool  insurance  policy  provides  for  insurance  against  that  type of  loss.
Depending  upon the nature of the event,  a breach of  representation  made by a
seller may also have  occurred.  That breach,  if it  materially  and  adversely
affects the interests of certificateholders and cannot be cured, would give rise
to a purchase obligation on the part of the seller, as described under 'Mortgage
Loan Program -- Representations  by Sellers.'  However,  such an event would not
give rise to a breach of a representation and warranty or a purchase  obligation
on the part of the depositor or Residential Funding Corporation.

     The original  amount of coverage under each mortgage pool insurance  policy
will be  reduced  over the life of the  related  series of  certificates  by the
aggregate  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  includes  some  expenses   incurred  by  the  master  servicer  or
subservicer as well as accrued interest on delinquent mortgage loans to the date
of payment of the claim.  See 'Certain  Legal  Aspects of Mortgage  Loans -- The
Mortgage Loans -- Foreclosure on Mortgage Loans.' Accordingly,  if aggregate net
claims paid under any mortgage pool insurance  policy reach the original  policy
limit, coverage under that mortgage pool insurance policy will be

                                       39



<PAGE>



<PAGE>

exhausted   and   any   further   losses   will   be   borne   by  the   related
certificateholders.  In addition,  unless the master servicer determines that an
Advance  relating to a delinquent  mortgage loan would be recoverable to it from
the proceeds of the  liquidation  of the mortgage loan or otherwise,  the master
servicer would not be obligated to make an Advance  respecting  any  delinquency
since the  Advance  would not be  ultimately  recoverable  to it from either the
mortgage  pool  insurance   policy  or  from  any  other  related  source.   See
'Description of the Certificates -- Advances.'

     Since each  mortgage pool  insurance  policy will require that the property
subject to a defaulted mortgage loan be restored to its original condition prior
to claiming  against  the pool  insurer,  the policy  will not provide  coverage
against hazard losses. As described under 'Insurance  Policies on Mortgage Loans
- -- Standard  Hazard  Insurance on  Mortgaged  Properties,'  the hazard  policies
covering the mortgage  loans  typically  exclude from coverage  physical  damage
resulting  from a number of causes  and,  even when the damage is  covered,  may
afford  recoveries  which are  significantly  less than full replacement cost of
those losses. Additionally,  no coverage for Special Hazard Losses, Fraud Losses
or Bankruptcy  Losses will cover all risks,  and the amount of any such coverage
will be limited. See ' -- Special Hazard Insurance Policies' below. As a result,
certain  hazard  risks  will  not  be  insured  against  and  may  be  borne  by
certificateholders.

SPECIAL HAZARD INSURANCE POLICIES

     Any insurance  policy  covering  Special Hazard Losses obtained for a trust
will be issued by the insurer named in the related prospectus  supplement.  Each
special  hazard  insurance  policy  subject  to  limitations  described  in this
paragraph  and in the related  prospectus  supplement,  if any, will protect the
related  certificateholders from Special Hazard Losses. Aggregate claims under a
special hazard  insurance  policy will be limited to the amount set forth in the
related  pooling and  servicing  agreement  and will be subject to  reduction as
described  in the related  pooling and  servicing  agreement.  A special  hazard
insurance  policy will provide  that no claim may be paid unless  hazard and, if
applicable,  flood insurance on the property securing the mortgage loan has been
kept in force and other protection and  preservation  expenses have been paid by
the master servicer.

     In accordance with the foregoing  limitations,  a special hazard  insurance
policy will  provide  that,  where there has been damage to property  securing a
foreclosed  mortgage loan, title to which has been acquired by the insured,  and
to the extent the damage is not covered by the hazard  insurance policy or flood
insurance policy, if any,  maintained by the mortgagor or the master servicer or
the  subservicer,  the insurer  will pay the lesser of (i) the cost of repair or
replacement of the related property or (ii) upon transfer of the property to the
insurer,  the  unpaid  principal  balance  of the  mortgage  loan at the time of
acquisition  of  the  related  property  by  foreclosure  or  deed  in  lieu  of
foreclosure,  plus accrued  interest at the  mortgage  rate to the date of claim
settlement  and  certain  expenses  incurred  by  the  master  servicer  or  the
subservicer with respect to the related property.

     If the property is  transferred  to a third party in a sale approved by the
special hazard insurer, the amount that the special hazard insurer will pay will
be the amount  under (ii) above  reduced by the net  proceeds of the sale of the
property.  If the  unpaid  principal  balance  plus  accrued  interest  and some
expenses is paid by the special hazard insurer,  the amount of further  coverage
under the related special hazard insurance policy will be reduced by that amount
less any net proceeds from the sale of the property. Any amount paid as the cost
of  repair  of the  property  will  further  reduce  coverage  by  that  amount.
Restoration  of the property  with the proceeds  described  under (i) above will
satisfy  the  condition  under each  mortgage  pool  insurance  policy  that the
property  be restored  before a claim under the policy may be validly  presented
with respect to the defaulted mortgage loan secured by the related property. The
payment described under (ii) above will render  presentation of a claim relating
to a mortgage loan under the related mortgage pool insurance policy unnecessary.
Therefore,  so long as a mortgage pool insurance  policy remains in effect,  the
payment by the insurer under a special  hazard  insurance  policy of the cost of
repair or of the unpaid  principal  balance of the  related  mortgage  loan plus
accrued interest and some expenses will not affect the total Insurance  Proceeds
paid to  certificateholders,  but will affect the  relative  amounts of coverage
remaining  under the related special hazard  insurance  policy and mortgage pool
insurance policy.

     To the extent described in the related prospectus supplement,  coverage for
Special Hazard Losses for a series of certificates may be provided,  in whole or
in part,  by a type of  special  hazard  coverage  other  than a special  hazard
insurance policy or by means of a representation of the depositor or Residential
Funding Corporation.

BANKRUPTCY POLICIES

     In the event of a personal  bankruptcy of a mortgagor,  a bankruptcy  court
may  establish  the value of the mortgaged  property of the  mortgagor,  and, if
specified  in  the  related  prospectus   supplement,   any  related  Additional
Collateral,  at a Deficient Valuation. The amount of the secured debt could then
be reduced to that  value,  and,  thus,  the holder of the  mortgage  loan would
become an unsecured creditor to the extent the outstanding  principal balance of
the mortgage loan exceeds the value assigned to the mortgaged property,  and any
related Additional Collateral, by the bankruptcy court.

     In addition, other modifications of the terms of a mortgage loan can result
from a bankruptcy proceeding,  including a Debt Service Reduction.  See 'Certain
Legal  Aspects  of  Mortgage  Loans -- The  Mortgage  Loans  --  Anti-Deficiency
Legislation and Other  Limitations on Lenders.' Any bankruptcy policy to provide
coverage for  Bankruptcy  Losses  resulting from  proceedings  under the federal
Bankruptcy  Code  obtained for a trust will be issued by an insurer named in the
related  prospectus  supplement.  The level of  coverage  under each  bankruptcy
policy will be set forth in the related prospectus supplement.

RESERVE FUNDS

     If so specified in the related  prospectus  supplement,  the depositor will
deposit or cause to be deposited in a reserve fund,  any  combination of cash or
Permitted Investments in specified amounts, or any other instrument satisfactory
to the rating  agency or Agencies,  which will be applied and  maintained in the
manner and under the conditions  specified in the related  pooling and servicing
agreement.  In the  alternative  or in addition to that  deposit,  to the extent
described  in the related  prospectus  supplement,  a reserve fund may be funded
through  application  of all or a portion  of amounts  otherwise  payable on any
related certificates,  from the Excess Spread,  Excluded Spread or otherwise. To
the  extent  that the  funding  of the  reserve  fund is  dependent  on  amounts
otherwise  payable on related  certificates,  Excess Spread,  Excluded Spread or
other cash flows  attributable to the related  mortgage loans or on reinvestment
income,  the reserve fund may provide less coverage than  initially  expected if
the cash flows or  reinvestment  income on which the  funding is  dependent  are
lower than anticipated.

     With respect to any series of certificates  as to which credit  enhancement
includes  a  letter  of  credit,  if so  specified  in  the  related  prospectus
supplement,  under specified circumstances the remaining amount of the letter of
credit may be drawn by the trustee and deposited in a reserve fund. Amounts in a
reserve fund may be distributed to  certificateholders,  or applied to reimburse
the master servicer for outstanding Advances, or may be used for other purposes,
in the manner and to the extent specified in the related prospectus  supplement.
If so specified in the related prospectus supplement,  amounts in a reserve fund
may be available only to cover  specific types of losses,  or losses on specific
mortgage loans. Unless otherwise specified in the related prospectus supplement,
any reserve fund will not be deemed to be part of the related  trust.  A reserve
fund may provide coverage to more than one series of certificates,  if set forth
in the related prospectus supplement.

     The trustee will have a perfected  security interest for the benefit of the
certificateholders  in the  assets in the  reserve  fund,  unless the assets are
owned by the  related  trust.  However,  to the extent that the  depositor,  any
affiliate  of the  depositor  or any other entity has an interest in any reserve
fund, in the event of the bankruptcy, receivership or insolvency of that entity,
there could be delays in withdrawals from the reserve fund and the corresponding
payments to the  certificateholders.  These  delays could  adversely  affect the
yield to investors on the related certificates.

     Amounts  deposited  in any  reserve  fund for a series  will be invested in
Permitted  Investments  by, or at the  direction  of, and for the benefit of the
master servicer or any other person named in the related prospectus supplement.

CERTIFICATE INSURANCE POLICIES; SURETY BONDS

     If so specified in the related  prospectus  supplement,  the  depositor may
obtain one or more certificate  insurance  policies or guaranties or one or more
surety  bonds,  or one or more  guarantees  issued by insurers or other  parties
acceptable to the rating agency or Agencies rating the certificates  offered, as
specified in the related prospectus  supplement,  insuring the holders of one or
more classes of  certificates  the payment of amounts due in accordance with the
terms of that class or those classes of certificates.  Any certificate insurance
policy, surety bond or guaranty will have the characteristics  described in, and
will be in accordance  with any  limitations  and  exceptions  described in, the
related prospectus supplement.

MAINTENANCE OF CREDIT ENHANCEMENT

     If credit  enhancement has been obtained for a series of certificates,  the
master  servicer  will be obligated to exercise its best  reasonable  efforts to
keep or  cause  to be kept the  credit  enhancement  in full  force  and  effect
throughout the term of the applicable  pooling and servicing  agreement,  unless
coverage  thereunder has been exhausted  through payment of claims or otherwise,
or  substitution  therefor is made as  described  below under ' --  Reduction or
Substitution of Credit  Enhancement.' The master servicer,  on behalf of itself,
the trustee  and  certificateholders,  will be  required to provide  information
required for the trustee to draw under any applicable credit enhancement.

     The master  servicer,  the servicer or the Certificate  Administrator  will
agree to pay the premiums  for each  mortgage  pool  insurance  policy,  special
hazard insurance  policy,  bankruptcy  policy,  certificate  insurance policy or
surety bond,  as  applicable,  on a timely  basis,  unless the premiums are paid
directly by the trust. As to mortgage pool insurance policies generally,  in the
event the related insurer ceases to be a Qualified Insurer,  the master servicer
will use its best reasonable  efforts to obtain from another Qualified Insurer a
comparable  replacement insurance policy with a total coverage equal to the then
outstanding  coverage of the policy.  If the cost of the  replacement  policy is
greater than the cost of the existing  policy,  the coverage of the  replacement
policy will, unless otherwise agreed to by the depositor,  be reduced to a level
so that its  premium  rate does not  exceed  the  premium  rate on the  original
insurance  policy.  In the event that a pool  insurer  ceases to be a  Qualified
Insurer  because it ceases to be approved as an insurer by the Federal Home Loan
Mortgage Corporation,  or Freddie Mac, the Federal National Mortgage Association
or Fannie Mae or any successor entity, the master servicer will review, not less
often than  monthly,  the  financial  condition  of the pool insurer with a view
toward  determining  whether recoveries under the mortgage pool insurance policy
are  jeopardized  for reasons  related to the  financial  condition  of the pool
insurer.  If the master servicer  determines that recoveries are so jeopardized,
it will exercise its best  reasonable  efforts to obtain from another  Qualified
Insurer a  replacement  insurance  policy as described  above,  at the same cost
limit.  Any  losses  in market  value of the  certificates  associated  with any
reduction or withdrawal in rating by an applicable  rating agency shall be borne
by the certificateholders.

     If any property securing a defaulted mortgage loan is damaged and proceeds,
if any,  from the related  hazard  insurance  policy or any  applicable  special
hazard  insurance  policy are  insufficient to restore the damaged property to a
condition  sufficient to permit  recovery  under any letter of credit,  mortgage
pool  insurance  policy or any  related  primary  insurance  policy,  the master
servicer is not required to expend its own funds to restore the damaged property
unless it determines (i) that  restoration  will increase the proceeds to one or
more classes of  certificateholders  on  liquidation  of the mortgage loan after
reimbursement of the master servicer for its expenses and (ii) that the expenses
will be recoverable by it through Liquidation Proceeds or Insurance Proceeds. If
recovery  under any letter of credit,  mortgage  pool  insurance  policy,  other
credit  enhancement  or any related  primary  insurance  policy is not available
because the master  servicer  has been unable to make the above  determinations,
has made the  determinations  incorrectly  or recovery is not  available for any
other reason,  the master servicer is nevertheless  obligated to follow whatever
normal practices and procedures, in accordance with the preceding sentence, that
it deems necessary or advisable to realize upon the defaulted  mortgage loan and
in the event this  determination  has been  incorrectly  made,  is  entitled  to
reimbursement of its expenses in connection with the restoration.

REDUCTION OR SUBSTITUTION OF CREDIT ENHANCEMENT

     The  amount  of credit  support  provided  with  respect  to any  series of
certificates  and  relating to various  types of losses  incurred may be reduced
under specified  circumstances.  In most cases,  the amount  available as credit
support will be subject to periodic  reduction on a  non-discretionary  basis in
accordance  with a schedule  or formula  set forth in the  related  pooling  and
servicing  agreement.  Additionally,  in most cases,  the credit  support may be
replaced,  reduced or terminated, and the formula used in calculating the amount
of coverage with respect to Bankruptcy  Losses,  Special  Hazard Losses or Fraud
Losses may be changed,  without the consent of the certificateholders,  upon the
written  assurance  from each  applicable  rating  agency that the  then-current
rating of the related  series of  certificates  will not be  adversely  affected
thereby.

     Furthermore,  in the event that the credit  rating of any obligor under any
applicable credit enhancement is downgraded,  the credit rating of each class of
the related certificates may be downgraded to a corresponding level, and, unless
otherwise  specified in the related  prospectus  supplement,  neither the master
servicer nor the

                                       42



<PAGE>



<PAGE>

depositor  will be obligated to obtain  replacement  credit  support in order to
restore  the  rating  of the  certificates.  The  master  servicer  will also be
permitted  to  replace  any  credit   support  with  other  credit   enhancement
instruments  issued by  obligors  whose  credit  ratings are  equivalent  to the
downgraded level and in lower amounts which would satisfy the downgraded  level,
provided  that the  then-current  rating of each class of the related  series of
certificates is maintained. Where the credit support is in the form of a reserve
fund, a permitted reduction in the amount of credit enhancement will result in a
release of all or a portion of the assets in the reserve fund to the  depositor,
the master servicer or any other person that is entitled thereto.  Any assets so
released and any amount by which the credit  enhancement  is reduced will not be
available for distributions in future periods.

            OTHER FINANCIAL OBLIGATIONS RELATED TO THE CERTIFICATES

SWAPS AND YIELD SUPPLEMENT AGREEMENTS

     The trustee on behalf of the trust may enter into  interest  rate swaps and
related caps, floors and collars to minimize the risk of certificateholders from
adverse  changes in interest  rates,  and other yield  supplement  agreements or
similar yield  maintenance  arrangements  that do not involve swap agreements or
other notional principal contracts.

     An  interest  rate swap is an  agreement  between two parties to exchange a
stream of interest  payments on an agreed  hypothetical or 'notional'  principal
amount.  No  principal  amount is  exchanged  between the  counterparties  to an
interest rate swap. In the typical swap, one party agrees to pay a fixed rate on
a notional  principal amount,  while the counterparty pays a floating rate based
on one or more reference  interest rates including the London Interbank  Offered
Rate or,  LIBOR,  a specified  bank's  prime rate or U.S.  Treasury  Bill rates.
Interest  rate swaps also  permit  counterparties  to  exchange a floating  rate
obligation based upon one reference interest rate, such as LIBOR, for a floating
rate obligation based upon another referenced interest rate, such as U.S.
Treasury Bill rates.

     The swap market has grown  substantially in recent years with a significant
number of banks and financial  service  firms acting both as  principals  and as
agents utilizing  standardized swap documentation.  Caps, floors and collars are
more recent innovations, and they are less liquid than other swaps.

     Yield supplement  agreements may be entered into to supplement the interest
rate or other rates on one or more classes of the certificates of any series.

     There  can be no  assurance  that the trust  will be able to enter  into or
offset swaps or enter into yield  supplement  agreements at any specific time or
at prices or on other terms that are  advantageous.  In  addition,  although the
terms of the swaps and yield  supplement  agreements may provide for termination
under some circumstances,  there can be no assurance that the trust will be able
to terminate a swap or yield supplement  agreement when it would be economically
advantageous to the trust to do so.

PURCHASE OBLIGATIONS

     Some types of mortgage loans and classes of certificates of any series,  as
specified  in the related  prospectus  supplement,  may be subject to a purchase
obligation. The terms and conditions of each purchase obligation,  including the
purchase price,  timing and payment procedure,  will be described in the related
prospectus supplement.  A purchase obligation with respect to mortgage loans may
apply to those  mortgage  loans or to the related  certificates.  Each  purchase
obligation may be a secured or unsecured  obligation of its provider,  which may
include a bank or other  financial  institution  or an insurance  company.  Each
purchase obligation will be evidenced by an instrument  delivered to the trustee
for the benefit of the  applicable  certificateholders  of the  related  series.
Unless otherwise specified in the related prospectus  supplement,  each purchase
obligation  with respect to mortgage loans will be payable solely to the trustee
for the benefit of the  certificateholders of the related series. Other purchase
obligations  may be payable to the  trustee or  directly  to the  holders of the
certificates to which the obligation relate.

<PAGE>

                      INSURANCE POLICIES ON MORTGAGE LOANS

     Each  mortgage  loan will be required  to be covered by a hazard  insurance
policy,  as described  below,  and, at times, a primary  insurance  policy or an
alternative  form of  coverage,  as described  below.  The  descriptions  of any
insurance policies contained in this prospectus or any prospectus supplement and
the coverage thereunder do not purport to be complete and are qualified in their
entirety by reference to the forms of policies.

PRIMARY INSURANCE POLICIES

     Unless otherwise specified in the related prospectus  supplement,  (i) each
mortgage loan having an LTV ratio at  origination of over 80% will be covered by
a primary  mortgage  guaranty  insurance  policy insuring against default on the
mortgage  loan up to an amount set forth in the related  prospectus  supplement,
unless  and until the  principal  balance of the  mortgage  loan is reduced to a
level that would  produce an LTV ratio  equal to or less than 80%,  and (ii) the
depositor  will  represent  and  warrant  that,  to the best of the  depositor's
knowledge,  the mortgage  loans are so covered.  Alternatively,  coverage of the
type that would be provided  by a primary  insurance  policy if obtained  may be
provided by another form of credit  enhancement as described in this  prospectus
under 'Description of Credit  Enhancement.'  However, the foregoing standard may
vary  significantly  depending on the  characteristics of the mortgage loans and
the applicable underwriting standards. A mortgage loan will not be considered to
be an exception to the  foregoing  standard if no primary  insurance  policy was
obtained at  origination  but the mortgage  loan has amortized to an 80% or less
LTV ratio level as of the applicable  cut-off date. In most cases, the depositor
will have the ability to cancel any primary insurance policy if the LTV ratio of
the mortgage loan is reduced to 80% or less, or a lesser  specified  percentage,
based on an appraisal of the mortgaged  property after the related  closing date
or as a result of principal  payments that reduce the  principal  balance of the
mortgage loan after the closing date.

     Mortgage  loans  which are subject to  negative  amortization  will only be
covered by a primary  insurance  policy if that coverage was required upon their
origination,  notwithstanding  that subsequent  negative  amortization may cause
that  mortgage  loan's  LTV  ratio,  based  on  the  then-current   balance,  to
subsequently  exceed the limits which would have  required  coverage  upon their
origination.  Primary insurance policies may be required to be obtained and paid
for by the mortgagor, or may be paid for by the servicer.

     While the terms and conditions of the Primary Insurance  Policies issued by
one primary mortgage  guaranty insurer will usually differ from those in Primary
Insurance  Policies  issued by other primary  insurers,  each primary  insurance
policy generally will pay either:

      the insured percentage of the loss on the related mortgaged property;

      the entire amount of the loss, after receipt by the primary insurer of
      good and merchantable title to, and possession of, the mortgaged property;
      or

      at the option of the  primary  insurer  under  certain  Primary  Insurance
      Policies,  the sum of the  delinquent  monthly  payments plus any Advances
      made  by  the  insured,  both  to  the  date  of the  claim  payment  and,
      thereafter,  monthly  payments  in the amount  that would have  become due
      under the mortgage  loan if it had not been  discharged  plus any Advances
      made by the insured  until the earlier of (a) the date the  mortgage  loan
      would have been  discharged in full if the default had not occurred or (b)
      an approved sale.

     The  amount  of the loss as  calculated  under a primary  insurance  policy
covering a  mortgage  loan will in most  cases  consist of the unpaid  principal
amount of such  mortgage  loan and  accrued  and  unpaid  interest  thereon  and
reimbursement of some expenses, less:

      rents or other payments  received by the insured,  other than the proceeds
      of hazard insurance, that are derived from the related mortgaged property;

      hazard insurance  proceeds received by the insured in excess of the amount
      required to restore the mortgaged property and which have not been applied
      to the payment of the mortgage loan;

      amounts expended but not approved by the primary insurer;

      claim payments previously made on the mortgage loan; and

      unpaid premiums and other amounts.

     As conditions precedent to the filing or payment of a claim under a primary
insurance  policy,  in the event of default by the  mortgagor,  the insured will
typically be required, among other things, to:

                                       44



<PAGE>



<PAGE>

      advance or discharge  (a) hazard  insurance  premiums and (b) as necessary
      and  approved  in advance  by the  primary  insurer,  real  estate  taxes,
      protection and preservation expenses and foreclosure and related costs;

      in the event of any  physical  loss or damage to the  mortgaged  property,
      have the  mortgaged  property  restored to at least its  condition  at the
      effective  date of the primary  insurance  policy,  ordinary wear and tear
      excepted; and

      tender to the primary insurer good and merchantable title to, and
      possession of, the mortgaged property.

     For any  certificates  offered under this  prospectus,  the master servicer
will maintain or cause each subservicer to maintain, as the case may be, in full
force and effect and to the extent  coverage is  available  a primary  insurance
policy with regard to each  mortgage loan for which  coverage is required  under
the standard  described  above unless an exception to such  standard  applies or
alternate credit  enhancement is provided as described in the related prospectus
supplement;  provided that the primary  insurance  policy was in place as of the
cut-off date and the depositor had knowledge of such primary  insurance  policy.
If the depositor  gains  knowledge  that as of the closing date, a mortgage loan
had an LTV ratio at  origination  in excess of 80% and was not the  subject of a
primary insurance policy,  and was not included in any exception to the standard
or  covered  by  alternate  credit  enhancement  as  described  in  the  related
prospectus  supplement,  and that the mortgage loan has a then current LTV ratio
in excess of 80%,  then the master  servicer is  required to use its  reasonable
efforts to obtain and maintain a primary  insurance  policy to the extent that a
policy is obtainable at a reasonable price.

STANDARD HAZARD INSURANCE ON MORTGAGED PROPERTIES

     The terms of the mortgage loans, other than Cooperative Loans, require each
mortgagor to maintain a hazard insurance  policy covering the related  mortgaged
property and  providing for coverage at least equal to that of the standard form
of fire insurance policy with extended coverage  customary in the state in which
the property is located.  Most coverage will be in an amount equal to the lesser
of the principal  balance of the mortgage loan or 100% of the insurable value of
the improvements securing the mortgage loan. The pooling and servicing agreement
will  provide  that the  master  servicer  or  servicer  shall  cause the hazard
policies to be  maintained  or shall obtain a blanket  policy  insuring  against
losses on the mortgage loans.  The ability of the master servicer to ensure that
hazard  insurance  proceeds  are  appropriately  applied may be dependent on its
being named as an additional insured under any hazard insurance policy and under
any  flood  insurance  policy  referred  to below,  or upon the  extent to which
information in this regard is furnished to the master  servicer by mortgagors or
subservicers.

     The standard  form of fire and extended  coverage  policy  covers  physical
damage to or destruction of the improvements on the property by fire, lightning,
explosion,  smoke,  windstorm,  hail,  riot,  strike  and  civil  commotion,  in
accordance  with the  conditions and  exclusions  specified in each policy.  The
policies  relating  to the  mortgage  loans will be  underwritten  by  different
insurers under  different  state laws in accordance  with  different  applicable
state forms and therefore will not contain  identical terms and conditions,  the
basic  terms  thereof are  dictated by  respective  state laws.  These  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 mudflows, nuclear reactions, wet
or dry rot, vermin,  rodents,  insects or domestic  animals,  theft and, in some
cases,  vandalism.  The  foregoing  list is merely  indicative  of some kinds of
uninsured risks and is not intended to be all-inclusive.  Where the improvements
securing a mortgage loan are located in a federally designated flood area at the
time of origination  of that mortgage loan, the pooling and servicing  agreement
generally  requires the master  servicer to cause to be maintained for each such
mortgage loan serviced,  flood insurance,  to the extent available, in an amount
equal to the lesser of the amount  required to compensate for any loss or damage
on a replacement cost basis or the maximum insurance available under the federal
flood insurance program.

     The hazard insurance policies covering the mortgaged  properties  typically
contain a co-insurance  clause that in effect requires the related  mortgagor at
all times to carry insurance of a specified percentage, typically 80% to 90%, of
the full  replacement  value of the  improvements  on the  property  in order to
recover the full amount of any partial loss. If the related mortgagor's coverage
falls below this specified  percentage,  this clause  usually  provides that the
insurer's  liability in the event of partial loss does not exceed the greater of
(i) the replacement cost of the improvements  damaged or destroyed less physical
depreciation or (ii) the proportion of

                                       45



<PAGE>



<PAGE>

the loss as the amount of insurance carried bears to the specified percentage of
the full replacement cost of the improvements.

     Since the  amount of hazard  insurance  that  mortgagors  are  required  to
maintain on the  improvements  securing  the  mortgage  loans may decline as the
principal balances owing thereon decrease, and since residential properties have
historically  appreciated in value over time, hazard insurance proceeds could be
insufficient  to restore  fully the  damaged  property in the event of a partial
loss.  See  'Subordination'  above for a description  of when  subordination  is
provided,  the protection,  limited to the Special Hazard Amount as described in
the related prospectus supplement,  afforded by subordination,  and 'Description
of Credit Enhancement -- Special Hazard Insurance Policies' for a description of
the limited  protection  afforded by any special hazard insurance policy against
losses occasioned by hazards which are otherwise uninsured against.

                                 THE DEPOSITOR

     The  depositor  is an indirect  wholly-owned  subsidiary  of GMAC  Mortgage
Group,  Inc.,  which is a wholly-owned  subsidiary of General Motors  Acceptance
Corporation.  The depositor was incorporated in the State of Delaware on January
25, 1985.  The  depositor  was organized for the purpose of serving as a private
secondary  mortgage market conduit.  The depositor  anticipates  that it will in
many cases have acquired mortgage loans indirectly through  Residential  Funding
Corporation,  which is also an indirect wholly-owned subsidiary of GMAC Mortgage
Group,  Inc. The  depositor  does not have,  nor is it expected in the future to
have, any significant assets.

     The  certificates  do not  represent an interest in or an obligation of the
depositor.  The  depositor's  only  obligations  with  respect  to a  series  of
certificates will be pursuant to limited  representations and warranties made by
the depositor or as otherwise provided in the related prospectus supplement.

     The  depositor  maintains  its  principal  office at 8400  Normandale  Lake
Boulevard,  Suite 600,  Minneapolis,  Minnesota  55437.  Its telephone number is
(612) 832-7000.

                        RESIDENTIAL FUNDING CORPORATION

     Unless   otherwise   specified  in  the  related   prospectus   supplement,
Residential Funding Corporation,  an affiliate of the depositor, will act as the
master servicer or manager for a series of certificates.

     Residential  Funding  Corporation  buys  conventional  mortgage loans under
several  loan  purchase  programs  from  mortgage  loan  originators  or sellers
nationwide,  including  affiliates,  that meet its  seller/servicer  eligibility
requirements  and  services  mortgage  loans for its own account and for others.
Residential  Funding  Corporation's  principal  executive offices are located at
8400 Normandale Lake Boulevard,  Suite 600,  Minneapolis,  Minnesota  55437. Its
telephone number is (612) 832-7000.  Residential  Funding  Corporation  conducts
operations  from its  headquarters  in Minneapolis  and from offices  located in
California,  New York,  Florida,  Georgia and  Maryland.  At December  31, 1998,
Residential Funding Corporation was master servicing a first lien loan portfolio
of approximately $55.0 billion and a second lien loan portfolio of approximately
$2.9 billion.

     Residential Funding  Corporation's  delinquency,  foreclosure and loan loss
experience  as of the end of the most  recent  calendar  quarter  for which that
information  is available on the  portfolio of loans for which it acts as master
servicer and that were originated under its modified loan purchase criteria will
be  summarized  in each  prospectus  supplement  relating to a mortgage pool for
which Residential Funding Corporation will act as master servicer.  There can be
no assurance that this experience will be representative of the results that may
be experienced with respect to any particular series of certificates.

                      THE POOLING AND SERVICING AGREEMENT

     As described in this prospectus  under  'Description of the Certificates --
General,'  each  series  of  certificates  will be issued  under a  pooling  and
servicing  agreement as  described  in that  section.  The  following  summaries
describe additional provisions common to each pooling and servicing agreement.

                                       46

<PAGE>

SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES

     The principal servicing  compensation to be paid to the master servicer for
its master servicing activities for each series of certificates will be equal to
the percentage per annum described in the related prospectus  supplement,  which
may vary under some circumstances,  of the outstanding principal balance of each
mortgage loan, and that  compensation will be retained by it from collections of
interest on the mortgage  loan in the related  trust,  after  provision has been
made for the  payment of  interest at the  applicable  pass-through  rate or Net
Mortgage Rate, as the case may be, to certificateholders  and for the payment of
any Excess Spread or Excluded Spread,  at the time the collections are deposited
into the applicable  Custodial  Account.  Notwithstanding  the  foregoing,  with
respect  to a series of  certificates  as to which the trust  includes  mortgage
securities,  the  compensation  payable to the master  servicer  or manager  for
servicing and administering the mortgage  securities on behalf of the holders of
the certificates may be based on a percentage per annum described in the related
prospectus  supplement of the outstanding  balance of those mortgage  securities
and may be retained from  distributions of interest thereon,  if so specified in
the related prospectus supplement.

     As compensation for its servicing  duties, a subservicer or, if there is no
subservicer,  the master servicer will be entitled to a monthly servicing fee as
described in the related  prospectus  supplement,  which may vary under  certain
circumstances  from the amounts  described in the  prospectus  supplement.  Some
subservicers may also receive additional  compensation in the amount of all or a
portion of the interest due and payable on the applicable mortgage loan which is
over and  above  the  interest  rate  specified  at the time  the  depositor  or
Residential Funding  Corporation,  as the case may be, committed to purchase the
mortgage loan. See 'Mortgage Loan Program -- Subservicing.' Subservicers will be
required to pay to the master servicer an amount equal to one month's  interest,
net of its  servicing  or  other  compensation,  on the  amount  of any  partial
Principal  Prepayment.  The master  servicer  will retain  these  amounts to the
extent  collected  from  subservicers.  In  addition,  the master  servicer or a
subservicer will retain all prepayment charges, assumption fees and late payment
charges,  to the extent  collected  from  mortgagors,  and any benefit which may
accrue from the  investment of funds in the Custodial  Account or the applicable
Certificate Account, to the extent not applied as Compensating Interest, or in a
Subservicing Account, as the case may be. In addition, some reasonable duties of
the master  servicer may be performed by an affiliate of the master servicer who
will be entitled to compensation therefor.

     The  master  servicer  will  pay or cause  to be paid  some of the  ongoing
expenses  associated  with each trust and incurred by it in connection  with its
responsibilities under the pooling and servicing agreement,  including,  without
limitation,  payment  of any fee or other  amount  payable  for any  alternative
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  subservicers   and  sellers.   The  master  servicer  will  be  entitled  to
reimbursement of expenses  incurred in enforcing the obligations of subservicers
and sellers  under  limited  circumstances.  In  addition,  as  indicated in the
preceding  section,  the master servicer will be entitled to reimbursements  for
some of the expenses incurred by it in connection with Liquidated Mortgage Loans
and in connection  with the restoration of mortgaged  properties,  such right of
reimbursement  being  prior to the rights of  certificateholders  to receive any
related Liquidation Proceeds, including Insurance Proceeds.

EVIDENCE AS TO COMPLIANCE

     Each pooling and servicing  agreement will provide that the master servicer
will, with respect to each series of certificates, deliver to the trustee, on or
before the date in each year  specified  in the related  pooling  and  servicing
agreement, an officer's certificate stating that:

      a review of the  activities  of the master  servicer  during the preceding
      calendar  year  relating  to its  servicing  of  mortgage  loans  and  its
      performance under pooling and servicing agreements, including that pooling
      and  servicing  agreement  has been  made  under the  supervision  of that
      officer;

      to the best of the officer's  knowledge,  based on the review,  the master
      servicer has complied in all material  respects with the minimum servicing
      standards set forth in the Uniform Single Attestation Program for Mortgage
      Bankers  and has  fulfilled  all its  obligations  under the  pooling  and
      servicing  agreement  throughout that year, or, if there has been material
      noncompliance  with the servicing  standards or a material  default in the
      fulfillment  of  any  such  obligation,  the  statement  shall  include  a
      description  of the  noncompliance  or specify each  default  known to the
      officer and the nature and status thereof; and

                                       47



<PAGE>



<PAGE>

      to the best of the officers'  knowledge,  each subservicer has complied in
      all material  respects with the minimum  servicing  standards set forth in
      the  Uniform  Single  Attestation  Program  for  Mortgage  Bankers and has
      fulfilled all of its material obligations under its subservicing agreement
      in all  material  respects  throughout  that  year,  or, if there has been
      material  noncompliance with the servicing standards or a material default
      in the  fulfillment  of such  obligations,  the statement  shall include a
      description of the noncompliance or specify each default,  as the case may
      be, known to the officer and the nature and status thereof.

     In addition,  each pooling and  servicing  agreement  will provide that the
master servicer will cause a firm of independent  public  accountants which is a
member of the American  Institute of Certified  Public  Accountants to furnish a
report  stating its opinion  that, on the basis of an  examination  conducted by
that firm substantially in accordance with standards established by the American
Institute  of  Certified  Public  Accountants,  the  assertions  made  regarding
compliance with the minimum servicing  standards set forth in the Uniform Single
Attestation  Program for Mortgage Bankers during the preceding calendar year are
fairly  stated in all material  respects,  subject to any  exceptions  and other
qualifications  that,  in the  opinion  of the firm,  the  accounting  standards
require it to report.  In  rendering  its  statement,  the firm may rely,  as to
matters relating to the direct  servicing of mortgage loans by subservicers,  on
comparable  statements  prepared in connection  with  examinations  conducted in
similar manners.

CERTAIN MATTERS REGARDING THE MASTER SERVICER AND THE DEPOSITOR

     The pooling and servicing  agreement for each series of  certificates  will
provide that the master  servicer may not resign from its obligations and duties
thereunder  except upon a  determination  that  performance  of its duties is no
longer permissible under applicable law or except in connection with a permitted
transfer of servicing. No resignation will become effective until the trustee or
a successor  servicer has assumed the master  servicer's  obligations and duties
under the pooling and servicing agreement.

     Each pooling and  servicing  agreement  will also provide  that,  except as
described below, 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 trust or the certificateholders for any action taken or for
refraining  from the taking of any action in good faith  under the  pooling  and
servicing 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 willful
misfeasance,  bad faith or gross  negligence in the  performance of duties or by
reason of reckless disregard of obligations and duties thereunder.  Each pooling
and  servicing  agreement  will further  provide that the master  servicer,  the
depositor, and any director,  officer,  employee or agent of the master servicer
or the  depositor is entitled to  indemnification  by the trust and will be held
harmless against any loss,  liability or expense incurred in connection with any
legal  action  relating to the pooling and  servicing  agreement  or the related
series of certificates, other than any loss, liability or expense related to any
specific  mortgage loan or mortgage  loans,  except any such loss,  liability or
expense otherwise  reimbursable under the pooling and servicing  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 pooling and servicing agreement will provide that neither
the master servicer nor the depositor will be under any obligation to appear in,
prosecute or defend any legal or administrative action that is not incidental to
its respective duties under the pooling and servicing 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 action which it may deem
necessary or desirable  with respect to the pooling and servicing  agreement and
the  rights  and  duties  of  the  parties  thereto  and  the  interests  of the
certificateholders  thereunder.  In that event,  the legal expenses and costs of
that action and any liability  resulting  therefrom will be expenses,  costs and
liabilities of the trust and the master  servicer or the depositor,  as the case
may be, will be entitled to be reimbursed  for the legal  expenses and costs out
of funds otherwise distributable to certificateholders.

     Any person into which the master  servicer  may be merged or  consolidated,
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 the pooling and
servicing  agreement,  provided  that (i) that  person is  qualified  to service
mortgage  loans on behalf  of Fannie  Mae or  Freddie  Mac and (ii) the  merger,
consolidation or succession does not adversely affect the then-current rating of
the classes of certificates

                                       48



<PAGE>



<PAGE>

of the related  series that have been rated.  In addition,  notwithstanding  the
prohibition on its resignation,  the master servicer may assign its rights under
a pooling and servicing  agreement to any person to whom the master  servicer is
transferring a substantial portion of its mortgage servicing portfolio, provided
clauses  (i) and  (ii)  above  are  satisfied  and  that  person  is  reasonably
satisfactory to the depositor and the trustee.  In the case of any assignment of
this type, the master servicer will be released from its  obligations  under the
pooling and  servicing  agreement,  exclusive  of  liabilities  and  obligations
incurred by it prior to the time of assignment.

EVENTS OF DEFAULT

     Events of default under the pooling and servicing agreement for a series of
certificates will include:

      any  failure by the  master  servicer  to make a  required  deposit to the
      Certificate  Account or, if the master  servicer is the paying  agent,  to
      distribute to the holders of any class of  certificates of that series any
      required payment which continues unremedied for five days after the giving
      of written notice of the 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 certificates of such class  evidencing not less than 25% of
      the aggregate percentage interests constituting that class;

      any  failure  by the  master  servicer  duly to  observe or perform in any
      material  respect any other of its  covenants or agreements in the pooling
      and servicing  agreement with respect to that series of certificates which
      continues  unremedied  for 30 days, or 15 days in the case of a failure to
      pay  the  premium  for  any  insurance  policy  which  is  required  to be
      maintained under the pooling and servicing agreement,  after the giving of
      written notice of the 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 any class of  certificates  of that series  evidencing not less
      than 25% of the aggregate  percentage  interests  constituting that class;
      and

      some events of insolvency, readjustment of debt, marshalling of assets and
      liabilities  or similar  proceedings  regarding  the master  servicer  and
      certain  actions by the  master  servicer  indicating  its  insolvency  or
      inability to pay its obligations.

     A default under the terms of any mortgage  securities included in any trust
will not constitute an event of default under the related  pooling and servicing
agreement.

RIGHTS UPON EVENT OF DEFAULT

     So long as an event of default remains unremedied,  either the depositor or
the trustee may, and, at the direction of the holders of certificates evidencing
not less than 51% of the aggregate voting rights in the related trust, except as
otherwise  provided  for in the related  pooling and  servicing  agreement  with
respect to the credit  enhancer,  the trustee shall, by written  notification to
the  master  servicer  and  to the  depositor  or the  trustee,  as  applicable,
terminate all of the rights and  obligations  of the master  servicer  under the
pooling and servicing agreement, other than any rights of the master servicer as
certificateholder,  covering the trust and in and to the mortgage  loans and the
proceeds  thereof,  whereupon  the trustee or, upon notice to the  depositor and
with the depositor's consent, its designee will succeed to all responsibilities,
duties and  liabilities  of the master  servicer under the pooling and servicing
agreement,  other than the  obligation  to  purchase  mortgage  loans under some
circumstances, and will be entitled to similar compensation arrangements. In the
event that the trustee would be obligated to succeed the master  servicer but is
unwilling  so to act,  it may  appoint  or if it is unable  so to act,  it shall
appoint or petition a court of competent  jurisdiction for the appointment of, a
Fannie Mae- or Freddie  Mac-approved  mortgage servicing  institution with a net
worth of at least  $10,000,000 to act as successor to the master  servicer under
the pooling and servicing  agreement,  unless otherwise set forth in the pooling
and servicing agreement. Pending appointment, the trustee is obligated to act in
that  capacity.  The trustee  and such  successor  may agree upon the  servicing
compensation to be paid,  which in no event may be greater than the compensation
to the initial master servicer under the pooling and servicing agreement.

     No  certificateholder  will have any right  under a pooling  and  servicing
agreement to institute any proceeding  with respect to the pooling and servicing
agreement, except as otherwise provided for in the related pooling and servicing
agreement with respect to the credit enhancer,  unless the holder previously has
given to the trustee written notice of default and the  continuance  thereof and
unless the holders of certificates of any class  evidencing not less than 25% of
the aggregate  percentage  interests  constituting  that class have made written
request upon the trustee to institute the  proceeding in its own name as trustee
thereunder and have offered to the

                                       49



<PAGE>



<PAGE>

trustee  reasonable  indemnity  and the trustee for 60 days after receipt of the
request and  indemnity  has  neglected or refused to institute  any  proceeding.
However,  the trustee will be under no  obligation to exercise any of the trusts
or powers vested in it by the pooling and  servicing  agreement or to institute,
conduct  or defend  any  litigation  thereunder  or in  relation  thereto at the
request, order or direction of any of the holders of certificates covered by the
pooling and servicing agreement,  unless the certificateholders  have offered to
the trustee  reasonable  security or indemnity  against the costs,  expenses and
liabilities which may be incurred therein or thereby.

AMENDMENT

     Each pooling and servicing  agreement may be amended by the depositor,  the
master   servicer  and  the   trustee,   without  the  consent  of  the  related
certificateholders:

      to cure any ambiguity;

      to correct or supplement any provision therein which may be inconsistent
      with any other provision therein or to correct any error;

      to change the timing and/or nature of deposits in the Custodial Account or
      the  Certificate  Account  or to change  the name in which  the  Custodial
      Account is maintained,  except that (a) the  Certificate  Account  deposit
      date may not occur  later  than the  related  distribution  date,  (b) the
      change may not adversely  affect in any material  respect the interests of
      any certificateholder,  as evidenced by an opinion of counsel, and (c) the
      change  may not  adversely  affect  the  then-current  rating of any rated
      classes of  certificates,  as evidenced  by a letter from each  applicable
      rating agency as specified in the related prospectus supplement;

      if an  election  to treat the  related  trust as a 'real  estate  mortgage
      investment conduit', or REMIC, has been made, to modify,  eliminate or add
      to any of its  provisions  (a) to the extent  necessary  to  maintain  the
      qualification  of the trust as a REMIC or to avoid or minimize the risk of
      imposition of any tax on the related trust,  provided that the trustee has
      received  an opinion of  counsel  to the  effect  that (1) that  action is
      necessary or desirable to maintain  qualification  or to avoid or minimize
      that risk,  and (2) the action will not  adversely  affect in any material
      respect the interests of any related  certificateholder,  or (b) to modify
      the  provisions  regarding  the  transferability  of  the  REMIC  residual
      certificates,  provided that the depositor has determined  that the change
      would not adversely  affect the  applicable  ratings of any classes of the
      certificates,  as evidenced by a letter from each applicable rating agency
      as  specified  in the  related  prospectus  supplement,  and that any such
      amendment  will not give rise to any tax with  respect to the  transfer of
      the REMIC residual certificates to a non-permitted transferee;

      to make any other provisions with respect to matters or questions  arising
      under  the  pooling  and  servicing  agreement  which  are not  materially
      inconsistent with its provisions, so long as the action will not adversely
      affect in any material respect the interests of any certificateholder; or

      to amend any provision that is not material to holders of any class of
      related certificates.

     The pooling and servicing  agreement may also be amended by the  depositor,
the master  servicer  and the trustee,  except as otherwise  provided for in the
related  pooling and servicing  agreement  with respect to the credit  enhancer,
with the consent of the holders of certificates  of each class affected  thereby
evidencing,  in  each  case,  not  less  than  66% of the  aggregate  percentage
interests constituting that class for the purpose of adding any provisions to or
changing in any manner or  eliminating  any of the provisions of the pooling and
servicing  agreement  or of  modifying  in any manner the rights of the  related
certificateholders,  except that no such  amendment may (i) reduce in any manner
the amount of, or delay the timing of, payments received on mortgage loans which
are required to be distributed on a certificate of any class without the consent
of the holder of the  certificate or (ii) reduce the percentage of  certificates
of any class the holders of which are required to consent to any such  amendment
unless the  holders of all  certificates  of that  class have  consented  to the
change in the percentage.

     Notwithstanding  the  foregoing,  if a REMIC  election  has been  made with
respect to the related trust, the trustee will not be entitled to consent to any
amendment to a pooling and servicing  agreement without having first received an
opinion of counsel to the effect that the amendment or the exercise of any power
granted to the

                                       50



<PAGE>



<PAGE>

master  servicer,  the depositor or the trustee in accordance with the amendment
will not result in the  imposition  of a tax on the  related  trust or cause the
trust to fail to qualify as a REMIC.

TERMINATION; RETIREMENT OF CERTIFICATES

     The primary  obligations created by the pooling and servicing agreement for
each  series of  certificates  will  terminate  upon the  payment to the related
certificateholders  of all  amounts  held in the  Certificate  Account or by the
master servicer and required to be paid to the certificateholders  following the
earlier of

      the final payment or other liquidation or disposition, or any Advance with
      respect  thereto,  of the  last  mortgage  loan  subject  thereto  and all
      property  acquired upon  foreclosure or deed in lieu of foreclosure of any
      mortgage loan and

      the purchase by the master  servicer or the  depositor or, if specified in
      the related  prospectus  supplement,  by the holder of the REMIC  residual
      certificates (see 'Material  Federal Income Tax Consequences'  below) from
      the trust for such series of all remaining mortgage loans and all property
      acquired in respect of the mortgage loans.

     Any option to purchase  described  in the second item above will be limited
to cases in which  the  aggregate  Stated  Principal  Balance  of the  remaining
mortgage  loans  is less  than or  equal to ten  percent  (10%)  of the  initial
aggregate  Stated  Principal  Balance of the mortgage  loans. In addition to the
foregoing, the master servicer or the depositor may have the option to purchase,
in whole but not in part, the certificates  specified in the related  prospectus
supplement in the manner described in the related  prospectus  supplement.  Upon
the purchase of such  certificates or at any time  thereafter,  at the option of
the master  servicer or the depositor,  the mortgage loans may be sold,  thereby
effecting a retirement of the  certificates and the termination of the trust, or
the  certificates  so purchased may be held or resold by the master  servicer or
the  depositor.  Written  notice of  termination  of the pooling  and  servicing
agreement will be given to each  certificateholder,  and the final  distribution
will be made only upon  surrender and  cancellation  of the  certificates  at an
office or agency  appointed by the trustee which will be specified in the notice
of termination.  If the  certificateholders are permitted to terminate the trust
under the applicable pooling and servicing  agreement,  a penalty may be imposed
upon the  certificateholders  based upon the fee that would be  foregone  by the
master servicer because of the related termination.

     Any purchase  described in the  preceding  paragraph of mortgage  loans and
property  acquired  relating  to the  mortgage  loans  evidenced  by a series of
certificates  shall be made at the option of the master servicer,  the depositor
or, if applicable,  the holder of the REMIC residual  certificates  at the price
specified in the related prospectus supplement.  The exercise of that right will
effect early retirement of the certificates of that series, but the right of any
entity to purchase the mortgage loans and related property will be in accordance
with the criteria, and will be at the price, set forth in the related prospectus
supplement.  Early  termination in this manner may adversely affect the yield to
holders of some classes of the certificates.  If a REMIC election has been made,
the  termination  of the related  trust will be effected in a manner  consistent
with applicable federal income tax regulations and its status as a REMIC.

     In  addition  to the  optional  repurchase  of the  property in the related
trust,  if so specified in the related  prospectus  supplement,  a holder of the
Call Class will have the  right,  solely at its  discretion,  to  terminate  the
related trust and thereby  effect early  retirement of the  certificates  of the
series,  on any distribution date after the 12th distribution date following the
date of initial  issuance of the related  series of  certificates  and until the
date  when the  optional  termination  rights  of the  master  servicer  and the
depositor  become  exercisable.  The Call Class  will not be  offered  under the
prospectus  supplement.  Any such call will be of the entire  trust at one time;
multiple calls with respect to any series of certificates will not be permitted.
In the case of a call,  the  holders  of the  certificates  will be paid a price
equal to the Call Price. To exercise the call, the Call  Certificateholder  must
remit to the related trustee for distribution to the  certificateholders,  funds
equal to the Call  Price.  If those  funds are not  deposited  with the  related
trustee,  the certificates of that series will remain outstanding.  In addition,
in the case of a trust for which a REMIC  election or elections  have been made,
this termination will be effected in a manner consistent with applicable Federal
income tax  regulations  and its status as a REMIC. In connection with a call by
the Call certificateholder,  the final payment to the certificateholders will be
made  upon  surrender  of the  related  certificates  to the  trustee.  Once the
certificates  have  been  surrendered  and paid in full,  there  will not be any
further liability to certificateholders.

                                       51

THE TRUSTEE

     The trustee under each pooling and servicing agreement will be named in the
related prospectus  supplement.  The commercial bank or trust company serving as
trustee may have normal  banking  relationships  with the  depositor  and/or its
affiliates, including Residential Funding Corporation.

     The trustee may resign at any time,  in which event the  depositor  will be
obligated  to appoint a successor  trustee.  The  depositor  may also remove the
trustee if the trustee  ceases to be  eligible to continue as trustee  under the
pooling and  servicing  agreement  or if the  trustee  becomes  insolvent.  Upon
becoming  aware of those  circumstances,  the  depositor  will be  obligated  to
appoint a successor trustee.  The trustee may also be removed at any time by the
holders of  certificates  evidencing  not less than 51% of the aggregate  voting
rights in the  related  trust.  Any  resignation  or removal of the  trustee and
appointment of a successor trustee will not become effective until acceptance of
the appointment by the successor trustee.

                              YIELD CONSIDERATIONS

     The yield to maturity of a certificate will depend on the price paid by the
holder for the certificate, the pass-through rate on any certificate entitled to
payments of interest,  which  pass-through  rate may vary if so specified in the
related prospectus  supplement,  and the rate and timing of principal  payments,
including prepayments,  defaults,  liquidations and repurchases, on the mortgage
loans  and the  allocation  thereof  to  reduce  the  principal  balance  of the
certificate or its notional amount, if applicable.

     Each monthly  interest  payment on a mortgage  loan will be  calculated  as
one-twelfth of the applicable  mortgage rate multiplied by the principal balance
of the mortgage loan outstanding as of the first day of the related due date for
the mortgage loan, subject to any deferred interest. The amount of payments with
respect to each  mortgage loan  distributed,  or accrued in the case of deferred
interest or accrual certificates,  monthly to holders of a class of certificates
entitled to payments of interest will be similarly calculated,  unless otherwise
specified in the prospectus  supplement,  on the basis of that class's specified
percentage  of each  payment  of  interest,  or  accrual  in the case of accrual
certificates,  and  will  be  expressed  as  a  fixed,  adjustable  or  variable
pass-through  rate  payable on the  outstanding  principal  balance or  notional
amount of the certificate,  or any combination of pass-through rates, calculated
as  described  in this  prospectus  and in the  related  prospectus  supplement.
Holders of strip  certificates or a class of certificates  having a pass-through
rate that varies based on the weighted  average  mortgage rate of the underlying
mortgage loans will be affected by disproportionate  prepayments and repurchases
of mortgage  loans having higher Net Mortgage  Rates or rates  applicable to the
strip certificates, as applicable.

     The effective yield to maturity to each holder of certificates  entitled to
payments of interest  will be below that  otherwise  produced by the  applicable
pass-through rate and purchase price of the certificate because,  while interest
will  accrue  on each  mortgage  loan  from the  first  day of each  month,  the
distribution of interest will be made on the 25th day or, if the 25th day is not
a business day, the next  succeeding  business  day, of the month  following the
month of accrual.

     A class of certificates  may be entitled to payments of interest at a fixed
pass-through rate, a variable pass-through rate or adjustable pass-through rate,
or any  combination  of  pass-through  rates,  each as  specified in the related
prospectus  supplement.  A variable pass-through rate may be calculated based on
the weighted  average of the Net Mortgage  Rates,  net of servicing fees and any
Excess Spread or Excluded  Spread,  of the related  mortgage loans for the month
preceding  the  distribution  date.  An  adjustable  pass-through  rate  may  be
calculated by reference to an index or otherwise.

     The  aggregate  payments of interest  on a class of  certificates,  and the
yield to maturity thereon,  will be affected by the rate of payment of principal
on the  certificates,  or the  rate  of  reduction  in the  notional  amount  of
certificates  entitled  to  payments  of  interest  only,  and,  in the  case of
certificates  evidencing  interests in ARM loans, by changes in the Net Mortgage
Rates on the ARM loans. See 'Maturity and Prepayment  Considerations' below. The
yield on the  certificates  will also be  affected by  liquidations  of mortgage
loans  following  mortgagor  defaults and by purchases of mortgage  loans in the
event  of  breaches  of  representations  made  for the  mortgage  loans  by the
depositor,  the master  servicer and others,  or  conversions  of ARM loans to a
fixed interest rate. See 'Mortgage Loan Program --  Representations  by Sellers'
and  'Description  of the  Certificates -- Assignment of Trust Assets' above. In
addition,  if the  index  used  to  determine  the  pass-through  rate  for  the
certificates is different than the index  applicable to the mortgage rates,  the
yield on the certificates

                                       52



<PAGE>



<PAGE>

will be sensitive to changes in the index related to the  pass-through  rate and
the yield on the  certificates  may be  reduced by  application  of a cap on the
pass-through rate based on the weighted average of the Net Mortgage Rates.

     In general, if a certificate is purchased at a premium over its face amount
and payments of principal on the related  mortgage  loans occur at a rate faster
than assumed at the time of purchase,  the purchaser's  actual yield to maturity
will be lower than that  anticipated at the time of purchase.  Conversely,  if a
class of  certificates  is  purchased  at a  discount  from its face  amount and
payments of principal on the related  mortgage loans occur at a rate slower than
that assumed at the time of purchase,  the purchaser's  actual yield to maturity
will be  lower  than  that  originally  anticipated.  The  effect  of  Principal
Prepayments,   liquidations   and  purchases  on  yield  will  be   particularly
significant in the case of a series of  certificates  having a class entitled to
payments of interest only or disproportionate payments of interest. This type of
class will likely be sold at a substantial  premium to its principal balance and
any faster than  anticipated rate of prepayments will adversely affect the yield
to its  holders.  In some  circumstances,  rapid  prepayments  may result in the
failure of the holders to recoup their  original  investment.  In addition,  the
yield to maturity on other types of classes of certificates,  including  accrual
certificates,  certificates with a pass-through  rate that fluctuates  inversely
with or at a multiple of an index or other  classes in a series  including  more
than one class of certificates,  may be relatively more sensitive to the rate of
prepayment on the related mortgage loans than other classes of certificates.

     The timing of changes in the rate of principal  payments on or  repurchases
of the mortgage  loans may  significantly  affect an investor's  actual yield to
maturity,  even if the average rate of principal payments  experienced over time
is  consistent  with an  investor's  expectation.  In  general,  the  earlier  a
prepayment of principal on the underlying  mortgage loans or a repurchase of the
mortgage  loans,  the  greater  will be the  effect  on an  investor's  yield to
maturity.  As a result,  the effect on an investor's yield of principal payments
and repurchases occurring at a rate higher or lower than the rate anticipated by
the investor during the period immediately following the issuance of a series of
certificates  would  not be fully  offset  by a  subsequent  like  reduction  or
increase in the rate of principal payments.

     When a full prepayment is made on a mortgage loan, the mortgagor is charged
interest on the principal  amount of the mortgage loan so prepaid for the number
of days in the month  actually  elapsed up to the date of the  prepayment,  at a
daily rate determined by dividing the mortgage rate by 365.  Prepayments in full
generally will reduce the amount of interest  distributed in the following month
to  holders  of  certificates  entitled  to  distributions  of  interest  if the
resulting Prepayment Interest Shortfall is not covered by Compensating Interest.
See  'Description  of the  Certificates  -- Prepayment  Interest  Shortfalls.' A
partial  prepayment  of  principal  is applied  so as to reduce the  outstanding
principal  balance of the related mortgage loan as of the first day of the month
in which the  partial  prepayment  is  received.  As a result,  the  effect of a
partial  prepayment  on a mortgage loan will be to reduce the amount of interest
distributed to holders of certificates in the month following the receipt of the
partial  prepayment by an amount equal to one month's interest at the applicable
pass-through  rate or Net  Mortgage  Rate,  as the case may be,  on the  prepaid
amount. See 'Description of the Certificates -- Prepayment Interest Shortfalls.'
Neither full or partial Principal  Prepayments nor Liquidation  Proceeds will be
distributed  until the  distribution  date in the month following  receipt.  See
'Maturity and Prepayment Considerations.'

     The rate of  defaults on the  mortgage  loans will also affect the rate and
timing of  principal  payments on the  mortgage  loans and thus the yield on the
certificates.  In general, defaults on mortgage loans are expected to occur with
greater  frequency in their early years.  The rate of default on mortgage  loans
which are refinance or limited  documentation  mortgage  loans,  and on mortgage
loans  with high LTV  ratios,  may be higher  than for other  types of  mortgage
loans.   Furthermore,   the  rate  and  timing  of  prepayments,   defaults  and
liquidations  on the  mortgage  loans will be affected  by the general  economic
condition of the region of the country in which the related mortgaged properties
are located.  The risk of delinquencies  and loss is greater and prepayments are
less likely in regions where a weak or deteriorating  economy exists,  as may be
evidenced by, among other factors,  increasing  unemployment or falling property
values.  The risk of loss may also be greater on mortgage  loans with LTV ratios
greater than 80% and with no primary insurance policies.  The yield on any class
of certificates  and the timing of principal  payments on that class may also be
affected by modifications or actions that may be approved by the master servicer
as  described  in  this  prospectus  under   'Description  of  the  Certificates
- --Collection and Other Servicing Procedures,' in connection with a mortgage loan
that is in default, or if a default is reasonably foreseeable.

                                       53

<PAGE>

     The risk of loss on mortgage  loans made on Puerto Rico mortgage  loans may
be greater  than on mortgage  loans that are made to  mortgagors  who are United
States  residents and citizens or that are secured by properties  located in the
United States. See 'Certain Legal Aspects of Mortgage Loans.'

     With respect to some mortgage loans, including ARM loans, the mortgage rate
at  origination  may be below the rate that would result if the index and margin
relating thereto were applied at origination.  Under the applicable underwriting
standards,  the mortgagor  under each mortgage loan usually will be qualified on
the basis of the mortgage  rate in effect at  origination.  The repayment of any
such mortgage loan may thus be dependent on the ability of the mortgagor to make
larger  monthly  payments  following  the  adjustment  of the mortgage  rate. In
addition,  the  periodic  increase  in the  amount  paid by the  mortgagor  of a
Buy-Down  Mortgage Loan during or at the end of the applicable  Buy-Down  Period
may  create a greater  financial  burden for the  mortgagor,  who might not have
otherwise  qualified  for a mortgage  under  Residential  Funding  Corporation's
underwriting  guidelines,  and may accordingly increase the risk of default with
respect to the related mortgage loan.

     The mortgage  rates on ARM loans that are subject to negative  amortization
typically   adjust  monthly  and  their   amortization   schedules  adjust  less
frequently.  During a period of  rising  interest  rates as well as  immediately
after  origination -- initial mortgage rates are typically lower than the sum of
the Indices applicable at origination and the related Note Margins -- the amount
of interest accruing on the principal balance of those mortgage loans may exceed
the amount of the scheduled  monthly payment thereon.  As a result, a portion of
the accrued interest on negatively amortizing mortgage loans may become deferred
interest which will be added to their  principal  balance and will bear interest
at the applicable mortgage rate.

     The  addition  of any  deferred  interest to the  principal  balance of any
related class of  certificates  will lengthen the weighted  average life of that
class  of  certificates  and may  adversely  affect  yield to  holders  of those
certificates.  In  addition,  with  respect  to ARM loans  that are  subject  to
negative amortization,  during a period of declining interest rates, it might be
expected  that each  scheduled  monthly  payment on such a  mortgage  loan would
exceed the amount of scheduled  principal and accrued  interest on its principal
balance, and since the excess will be applied to reduce the principal balance of
the related class or classes of certificates, the weighted average life of those
certificates will be reduced and may adversely affect yield to holders thereof.

     For each mortgage pool, if all necessary  Advances are made and if there is
no unrecoverable  loss on any mortgage loan, the net effect of each distribution
respecting  interest  will be to  pass-through  to  each  holder  of a class  of
certificates  entitled to  payments of interest an amount  which is equal to one
month's interest at the applicable  pass-through  rate on that class's principal
balance or notional  balance,  as adjusted  downward to reflect any  decrease in
interest  caused by any Principal  Prepayments  and the addition of any deferred
interest to the principal  balance of any mortgage loan. See 'Description of the
Certificates -- Distributions -- Principal and Interest on the Certificates.'

                     MATURITY AND PREPAYMENT CONSIDERATIONS

     As indicated  above under 'The Trusts -- The Mortgage  Loans,' the original
terms to  maturity  of the  mortgage  loans in a given  mortgage  pool will vary
depending  upon the type of mortgage  loans  included in the mortgage  pool. The
prospectus supplement for a series of certificates will contain information with
respect  to the  types  and  maturities  of the  mortgage  loans in the  related
mortgage pool. Unless otherwise specified in the related prospectus  supplement,
all of the mortgage loans may be prepaid  without  penalty in full or in part at
any time. The prepayment experience,  the timing and rate of repurchases and the
timing and amount of liquidations  with respect to the related mortgage loans in
a  mortgage  pool  will  affect  the life and  yield of the  related  series  of
certificates.

     With respect to Balloon Loans, payment of the Balloon Amount,  which, based
on the  amortization  schedule  of those  mortgage  loans,  is  expected to be a
substantial  amount,  will typically depend on the mortgagor's ability to obtain
refinancing of the mortgage loans or to sell the mortgaged property prior to the
maturity of the Balloon Loan. The ability to obtain refinancing will depend on a
number  of  factors  prevailing  at the time  refinancing  or sale is  required,
including,  without  limitation,  real estate values, the mortgagor's  financial
situation,  prevailing  mortgage loan interest rates, the mortgagor's  equity in
the  related  mortgaged  property,  tax laws  and  prevailing  general  economic
conditions.  Neither  the  depositor,  the  master  servicer  nor  any of  their
affiliates  will be obligated to refinance or repurchase any mortgage loan or to
sell the mortgaged property.

                                       54

     Prepayments  on  mortgage  loans  are  commonly   measured  relative  to  a
prepayment  standard  or model.  The  prospectus  supplement  for each series of
certificates  may  describe  one or more  prepayment  standard  or model and may
contain tables  setting forth the projected  yields to maturity on each class of
certificates  and/or the weighted average life of each class of certificates and
the percentage of the original principal amount of each class of certificates of
that series that would be outstanding on specified  payment dates for the series
based on the assumptions stated in the related prospectus supplement,  including
assumptions   that   prepayments  on  the  mortgage  loans  are  made  at  rates
corresponding to various  percentages of the prepayment standard or model. There
is no assurance  that  prepayment of the mortgage  loans  underlying a series of
certificates  will  conform  to any level of the  prepayment  standard  or model
specified in the related prospectus supplement.

     The following is a list of factors that may affect prepayment experience:

      homeowner mobility;

      economic conditions;

      changes in mortgagors' housing needs;

      job transfers;

      unemployment;

      mortgagors' equity in the properties securing the mortgages;

      servicing decisions;

      enforceability of due-on-sale clauses;

      mortgage market interest rates;

      mortgage recording taxes;

      solicitations and the availability of mortgage funds; and

      the obtaining of secondary financing by the mortgagor.

     Unless  otherwise  specified  in the  related  prospectus  supplement,  all
mortgage  loans,  other  than ARM loans,  will  contain  due-on-sale  provisions
permitting  the mortgagee to  accelerate  the maturity of the mortgage loan upon
sale or some  transfers by the mortgagor of the underlying  mortgaged  property.
Unless  the  related  prospectus  supplement  indicates  otherwise,  the  master
servicer will enforce any  due-on-sale  clause to the extent it has knowledge of
the conveyance or proposed  conveyance of the underlying  mortgaged property and
it is entitled to do so under applicable law, provided, however, that the master
servicer  will  not  take any  action  in  relation  to the  enforcement  of any
due-on-sale  provision which would adversely affect or jeopardize coverage under
any applicable insurance policy.

     An ARM loan is assumable, in some circumstances, if the proposed transferee
of the related mortgaged property  establishes its ability to repay the mortgage
loan and,  in the  reasonable  judgment  of the master  servicer  or the related
subservicer,  the  security  for the  ARM  loan  would  not be  impaired  by the
assumption.  The  extent to which ARM loans are  assumed  by  purchasers  of the
mortgaged properties rather than prepaid by the related mortgagors in connection
with the sales of the mortgaged properties will affect the weighted average life
of the related series of  certificates.  See 'Description of the Certificates --
Collection  and Other  Servicing  Procedures'  and  'Certain  Legal  Aspects  of
Mortgage Loans -- The Mortgage Loans --  Enforceability  of Certain  Provisions'
for a description of provisions of the pooling and servicing agreement and legal
developments that may affect the prepayment experience on the mortgage loans.

     In addition,  some mortgage  securities  included in a mortgage pool may be
backed  by  underlying   mortgage  loans  having   differing   interest   rates.
Accordingly,  the rate at which  principal  payments are received on the related
certificates  will,  to  some  extent,  depend  on  the  interest  rates  on the
underlying mortgage loans.

     A subservicer  may allow the refinancing of a mortgage loan in any trust by
accepting  prepayments  thereon and  permitting a new loan to the same  borrower
secured by a  mortgage  on the same  property,  which may be  originated  by the
subservicer or the master servicer or any of their  respective  affiliates or by
an unrelated  entity.  In the event of a refinancing,  the new loan would not be
included in the related trust and,  therefore,  the  refinancing  would have the
same effect as a prepayment in full of the related  mortgage loan. A subservicer
or the master servicer may, from time to time,  implement  programs  designed to
encourage   refinancing.   These  programs  may  include,   without  limitation,
modifications of existing loans, general or targeted solicitations, the

                                       55



<PAGE>



<PAGE>

offering  of  pre-approved  applications,  reduced  origination  fees or closing
costs, or other financial incentives.  Targeted  solicitations may be based on a
variety of factors,  including the credit of the borrower or the location of the
mortgaged  property.  In  addition,  subservicers  or the  master  servicer  may
encourage  assumptions of mortgage loans,  including  defaulted  mortgage loans,
under which  creditworthy  borrowers assume the outstanding  indebtedness of the
mortgage loans which may be removed from the related  mortgage pool. As a result
of these programs,  with respect to the mortgage pool underlying any trust,  the
rate of Principal  Prepayments of the mortgage loans in the mortgage pool may be
higher than would  otherwise be the case, and in some cases,  the average credit
or collateral  quality of the mortgage loans  remaining in the mortgage pool may
decline.

     All statistics  known to the depositor that have been compiled with respect
to  prepayment  experience on mortgage  loans  indicate that while some mortgage
loans may remain outstanding until their stated maturities, a substantial number
will be paid prior to their respective stated maturities.

     The rate of prepayment  with respect to  conventional  fixed-rate  mortgage
loans has  fluctuated  significantly  in recent  years.  For example,  published
principal  balance  information for Freddie Mac and Fannie Mae securities backed
by conventional  fixed-rate  mortgage loans indicates that the prepayment  rates
for those mortgage  securities were substantially lower during the high interest
rate climate  prevailing  during 1980,  1981 and early 1982 than the  prepayment
rates during 1985 and 1986 when prevailing interest rates declined.  In general,
if interest  rates fall below the mortgage rates on fixed-rate  mortgage  loans,
the rate of prepayment would be expected to increase. The depositor is not aware
of any historical  prepayment  experience with respect to mortgage loans secured
by  properties  located in Puerto Rico and,  accordingly,  prepayments  on those
loans may not occur at the same rate or be affected by the same factors as other
mortgage loans.

     Although  the  mortgage  rates on ARM loans  will be  subject  to  periodic
adjustments, the adjustments generally will:

      not increase or decrease the mortgage rates by more than a fixed
      percentage amount on each adjustment date;

      not increase the mortgage rates over a fixed percentage amount during the
      life of any ARM loan; and

      be based on an  index,  which  may not  rise  and fall  consistently  with
      mortgage  interest  rates,  plus the  related  Note  Margin,  which may be
      different  from  margins  being  used at the  time  for  newly  originated
      adjustable rate mortgage loans.

     As a result,  the mortgage rates on the ARM loans in a mortgage pool at any
time may not equal the prevailing rates for similar, newly originated adjustable
rate  mortgage  loans.  In some  rate  environments,  the  prevailing  rates  on
fixed-rate   mortgage  loans  may  be  sufficiently   low  in  relation  to  the
then-current  mortgage  rates  on ARM  loans  that the  rate of  prepayment  may
increase as a result of  refinancings.  There can be no certainty as to the rate
of  prepayments  on the mortgage loans during any period or over the life of any
series of certificates.

     Under some circumstances, the master servicer, the depositor or, if
specified in the related prospectus supplement, the holders of the REMIC
residual certificates may have the option to purchase the mortgage loans in a
trust. See 'The Pooling and Servicing Agreement -- Termination; Retirement of
Certificates.'

                    CERTAIN LEGAL ASPECTS OF MORTGAGE LOANS

     The  following  discussion  contains  summaries  of some  legal  aspects of
mortgage  loans that are  general in nature.  Because  these  legal  aspects are
governed in part by state law, which laws may differ substantially from state to
state,  the summaries do not purport to be complete,  to reflect the laws of any
particular  state or to encompass  the laws of all states in which the mortgaged
properties  may be situated.  The summaries  are qualified in their  entirety by
reference to the applicable federal and state laws governing the mortgage loans.

THE MORTGAGE LOANS

  General

     The mortgage loans,  other than Cooperative Loans, will be secured by deeds
of  trust,  mortgages  or deeds to secure  debt  depending  upon the  prevailing
practice in the state in which the related mortgaged property is

                                       56



<PAGE>



<PAGE>

located.  In some  states,  a  mortgage,  deed of trust or deed to  secure  debt
creates a lien upon the related real  property.  In other states,  the mortgage,
deed of trust or deed to secure debt conveys  legal title to the property to the
mortgagee  subject to a condition  subsequent,  for example,  the payment of the
indebtedness  secured thereby.  These  instruments are not prior to the lien for
real estate taxes and assessments  and other charges imposed under  governmental
police powers. Priority with respect to these instruments depends on their terms
and in some  cases on the  terms of  separate  subordination  or  inter-creditor
agreements,  and generally on the order of  recordation  of the mortgage deed of
trust or deed to secure debt in the appropriate recording office.

     There are two parties to a mortgage, the mortgagor, who is the borrower and
homeowner,  and the mortgagee, who is the lender. Under the mortgage instrument,
the mortgagor delivers to the mortgagee a note or bond and the mortgage. In some
states,  three parties may be involved in a mortgage financing when title to the
property is held by a land  trustee  under a land trust  agreement  of which the
borrower  is the  beneficiary;  at  origination  of a  mortgage  loan,  the land
trustee,  as fee owner of the  property,  executes the mortgage and the borrower
executes (1) a separate  undertaking  to make  payments on the mortgage note and
(2) an assignment of leases and rents.  Although a deed of trust is similar to a
mortgage,  a  deed  of  trust  has  three  parties:  the  trustor,  who  is  the
borrower/homeowner;  the  beneficiary,  who is  the  lender;  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, the grantee's authority
under a deed to secure debt  generally  with a power of sale,  to the trustee to
secure  payment  of the  obligation.  A deed to secure  debt  typically  has two
parties,  under  which  the  borrower,  or  grantor,  conveys  title to the real
property to the grantee,  or lender,  typically with a power of sale,  until the
time when the debt is repaid. The trustee's  authority under a deed of trust and
the mortgagee's  authority under a mortgage are governed by the law of the state
in which the real  property is located,  the express  provisions  of the deed of
trust, mortgage or deed to secure debt and, in some deed of trust, transactions,
the directions of the beneficiary.

  Cooperative Loans

     If  specified  in  the  prospectus  supplement  relating  to  a  series  of
certificates, the mortgage loans may include Cooperative Loans. Each Cooperative
Note  evidencing a  Cooperative  Loan will be secured by a security  interest in
shares issued by the Cooperative that owns the related apartment building, which
is a corporation  entitled to be treated as a housing  cooperative under federal
tax law, and in the related  proprietary lease or occupancy  agreement  granting
exclusive  rights  to  occupy  a  specific  dwelling  unit in the  Cooperative's
building.  The security  agreement  will create a lien upon, or grant a security
interest  in,  the  Cooperative  shares  and  proprietary  leases  or  occupancy
agreements,  the priority of which will depend on, among other things, the terms
of the particular  security agreement as well as the order of recordation of the
agreement,  or the filing of the financing  statements  related thereto,  in the
appropriate  recording  office or the taking of  possession  of the  Cooperative
shares,  depending on the law of the state in which the  Cooperative is located.
This type of lien or security  interest  is not,  in general,  prior to liens in
favor of the cooperative corporation for unpaid assessments or common charges.

     Generally,  each Cooperative owns in fee or has a leasehold interest in all
the real  property  and owns in fee or  leases  the  building  and all  separate
dwelling units therein.  The  Cooperative is directly  responsible  for property
management and, in most cases,  payment of real estate taxes, other governmental
impositions  and  hazard  and  liability  insurance.  If there is an  underlying
mortgage or mortgages on the  Cooperative's  building or underlying  land, as is
typically the case,  or an underlying  lease of the land, as is the case in some
instances, the Cooperative,  as mortgagor or lessee, as the case may be, is also
responsible for fulfilling the mortgage or rental obligations.

     An underlying  mortgage loan is ordinarily  obtained by the  Cooperative in
connection  with  either  the  construction  or  purchase  of the  Cooperative's
building or the  obtaining  of capital by the  Cooperative.  The interest of the
occupant  under  proprietary  leases or  occupancy  agreements  as to which that
Cooperative  is the  landlord is  generally  subordinate  to the interest of the
holder of an  underlying  mortgage  and to the  interest of the holder of a land
lease. If the Cooperative is unable to meet the payment  obligations (i) arising
under an underlying mortgage, the mortgagee holding an underlying mortgage could
foreclose on that mortgage and terminate all subordinate  proprietary leases and
occupancy  agreements  or (ii) arising  under its land lease,  the holder of the
landlord's  interest under the land lease could terminate it and all subordinate
proprietary leases and occupancy agreements. In addition, an underlying 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 final
payment

                                       57

<PAGE>

at maturity.  The inability of the  Cooperative  to refinance a mortgage and its
consequent  inability to make the final payment could lead to foreclosure by the
mortgagee.  Similarly,  a land lease has an expiration date and the inability of
the Cooperative to extend its term or, in the alternative, to purchase the land,
could lead to  termination  of the  Cooperative's  interest in the  property and
termination of all proprietary leases and occupancy agreements. In either event,
a foreclosure by the holder of an underlying  mortgage or the termination of the
underlying  lease could  eliminate  or  significantly  diminish the value of any
collateral  held by the  lender  who  financed  the  purchase  by an  individual
tenant-stockholder of shares of the Cooperative,  or in the case of the mortgage
loans, the collateral securing the Cooperative Loans.

     Each   Cooperative   is   owned   by    shareholders,    referred   to   as
tenant-stockholders,   who,  through   ownership  of  stock  or  shares  in  the
Cooperative,  receive  proprietary  leases or occupancy  agreements which confer
exclusive rights to occupy specific dwellings.  Generally,  a tenant-stockholder
of a Cooperative must make a monthly rental payment to the Cooperative under the
proprietary lease, which rental payment represents the  tenant-stockholder's pro
rata share of the  Cooperative's  payments  for its  underlying  mortgage,  real
property taxes,  maintenance expenses and other capital or ordinary expenses. An
ownership  interest in a Cooperative and  accompanying  occupancy  rights may be
financed  through a Cooperative Loan evidenced by a Cooperative Note and secured
by an  assignment  of and a security  interest  in the  occupancy  agreement  or
proprietary  lease and a security  interest in the related shares of the related
Cooperative.  The lender generally 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.  In  accordance  with  the
limitations discussed below, upon default of the tenant-stockholder,  the lender
may sue for judgment on the  Cooperative  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.  See '  Foreclosure  on Shares of  Cooperatives'
below.

  Tax Aspects of Cooperative Ownership

     In general, a 'tenant-stockholder',  as defined in Section 216(b)(2) of the
Internal  Revenue Code of 1986, or Internal  Revenue Code, of a corporation that
qualifies as a 'cooperative  housing  corporation' within the meaning of Section
216(b)(1) of the Internal  Revenue Code is allowed a deduction  for amounts paid
or accrued within his or her taxable year to the corporation representing his or
her  proportionate  share of certain  interest  expenses  and real estate  taxes
allowable as a deduction  under Section  216(a) of the Internal  Revenue Code to
the  corporation  under  Sections 163 and 164 of the Internal  Revenue  Code. In
order for a  corporation  to qualify  under  Section  216(b)(1)  of the Internal
Revenue  Code for its  taxable  year in which  those  items are  allowable  as a
deduction to the corporation,  the section requires, among other things, that at
least  80%  of  the  gross  income  of  the  corporation  be  derived  from  its
tenant-stockholders.  By virtue of this requirement, the status of a corporation
for  purposes  of  Section  216(b)(1)  of the  Internal  Revenue  Code  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 this section
for any  particular  year. In the event that 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  Section  216(a) of the  Internal  Revenue  Code with
respect to those years. In view of the significance of the tax benefits accorded
tenant-stockholders  of a corporation that qualifies under Section  216(b)(1) of
the Internal  Revenue Code,  the  likelihood  that this type of failure would be
permitted to continue over a period of years appears remote.

  Foreclosure on Mortgage Loans

     Although a deed of trust or a deed to secure debt may also be foreclosed by
judicial  action,  foreclosure  of a deed of trust or a deed to  secure  debt is
typically accomplished by a non-judicial trustee's or grantee's,  as applicable,
sale  under a  specific  provision  in the deed of trust or deed to secure  debt
which  authorizes the trustee or grantee,  as  applicable,  to sell the property
upon any default by the borrower under the terms of the note or deed of trust or
deed to secure debt. In addition to any notice requirements  contained in a deed
of trust or deed to secure  debt,  in some  states,  the trustee or grantee,  as
applicable,   must   record  a  notice  of  default  and  send  a  copy  to  the
borrower/trustor  and to any  person who has  recorded  a request  for a copy of
notice of default and notice of sale. In addition,  in some states,  the trustee
or grantee, as applicable, must provide notice to any other

                                       58



<PAGE>



<PAGE>

individual  having an interest  of record in the real  property,  including  any
junior  lienholders.  If the  deed  of  trust  or  deed  to  secure  debt is not
reinstated  within a  specified  period,  a notice  of sale  must be posted in a
public place and, in most states, published for a specific period of time in one
or more  newspapers.  In addition,  some states' 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.

     Foreclosure of a mortgage  generally is accomplished by judicial action. In
most cases,  the action is initiated by the service of legal  pleadings upon all
parties having an interest of record in the real property.  Delays in completion
of the  foreclosure  may  result  from  difficulties  in  locating  and  serving
necessary parties, including borrowers located outside the jurisdiction in which
the  mortgaged  property is located.  If the  mortgagee's  right to foreclose is
contested,  the  legal  proceedings  necessary  to  resolve  the  issue  can  be
time-consuming.

     In some states, the borrower-trustor has the right to reinstate the loan at
any time following  default until shortly before the trustee's sale. In general,
in those states,  the borrower,  or any other person having a junior encumbrance
on the real estate,  may,  during a  reinstatement  period,  cure the default by
paying the entire  amount in arrears  plus the costs and  expenses  incurred  in
enforcing the obligation.

     In the case of  foreclosure  under a  mortgage,  a deed of trust or deed to
secure  debt,  the sale by the  referee  or other  designated  officer or by the
trustee or grantee,  as applicable,  is a public sale.  However,  because of the
difficulty  a  potential  buyer at the sale may have in  determining  the  exact
status of title and because the  physical  condition  of the  property  may have
deteriorated  during the  foreclosure  proceedings,  it is uncommon  for a third
party to purchase the property at a foreclosure  sale.  Rather, it is common for
the lender to purchase the property from the trustee or grantee,  as applicable,
or referee for a credit bid less than or equal to the unpaid principal amount of
the  mortgage  or deed of trust  or deed to  secure  debt,  accrued  and  unpaid
interest and the expense of foreclosure, in which case the mortgagor's debt will
be extinguished  unless the lender purchases the property for a lesser amount in
order to preserve its right against a borrower to seek a deficiency judgment and
the remedy is available under state law and the related loan  documents.  In the
same states,  there is a statutory  minimum  purchase price which the lender may
offer  for the  property  and  generally,  state  law  controls  the  amount  of
foreclosure  costs  and  expenses,  including  attorneys'  fees,  which  may  be
recovered by a lender. Thereafter,  subject to the right of the borrower in some
states to remain in possession  during the  redemption  period,  the lender will
assume the burdens of ownership,  including  obtaining hazard insurance,  paying
taxes and making  repairs at its own expense  that are  necessary  to render the
property suitable for sale. Generally,  the lender will 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 and,
in some  states,  the lender may be entitled to a deficiency  judgment.  In some
cases, a deficiency judgment may be pursued in lieu of foreclosure. Any loss may
be reduced by the receipt of any mortgage  insurance  proceeds or other forms of
credit  enhancement  for a series of  certificates.  See  'Description of Credit
Enhancement.'

  Foreclosure on Mortgaged Properties Located in the Commonwealth of Puerto Rico

     Under the laws of the Commonwealth of Puerto Rico the foreclosure of a real
estate mortgage usually follows an ordinary 'civil action' filed in the Superior
Court for the district where the mortgage property is located.  If the defendant
does not  contest the action  filed,  a default  judgment  is  rendered  for the
plaintiff  and  the  mortgaged  property  is  sold  at  public  auction,   after
publication of the sale for two weeks, by posting written notice in three public
places in the municipality where the auction will be held, in the tax collection
office and in the public school of the municipality where the mortgagor resides,
if known. If the residence of the mortgagor is not known,  publication in one of
the newspapers of general circulation in the Commonwealth of Puerto Rico must be
made at least  once a week for two weeks.  There may be as many as three  public
sales of the mortgaged property. If the defendant contests the foreclosure,  the
case may be tried and judgment rendered based on the merits of the case.

     There are no  redemption  rights  after  the  public  sale of a  foreclosed
property  under the laws of the  Commonwealth  of Puerto Rico.  Commonwealth  of
Puerto Rico law  provides  for a summary  proceeding  for the  foreclosure  of a
mortgage,  but it is very seldom used because of concerns regarding the validity
of those  actions.  The process may be expedited if the mortgagee can obtain the
consent of the defendant to the execution of a deed in lieu of foreclosure.

                                       59

     Under  Commonwealth of Puerto Rico law, in the case of the public sale upon
foreclosure of a mortgaged  property that (a) is subject to a mortgage loan that
was  obtained  for a purpose  other than the  financing  or  refinancing  of the
acquisition,  construction or improvement of the property and (b) is occupied by
the  mortgagor as his principal  residence,  the mortgagor of the property has a
right to be paid the first $1,500 from the proceeds  obtained on the public sale
of the property. The mortgagor can claim this sum of money from the mortgagee at
any time prior to the public sale or up to one year after the sale. This payment
would reduce the amount of sales proceeds available to satisfy the mortgage loan
and may increase the amount of the loss.

  Foreclosure on Shares of Cooperatives

     The Cooperative shares owned by the  tenant-stockholder,  together with the
rights  of the  tenant-stockholder  under  the  proprietary  lease or  occupancy
agreement, are pledged to the lender and are, in almost all cases, in accordance
with restrictions on transfer as set forth in the  Cooperative's  certificate of
incorporation  and  by-laws,  as well as in the  proprietary  lease or occupancy
agreement. The proprietary lease or occupancy agreement, even while pledged, may
be canceled by the Cooperative for failure by the tenant-stockholder to pay rent
or  other  obligations  or  charges  owed by the  tenant-stockholder,  including
mechanics'   liens   against  the   Cooperative's   building   incurred  by  the
tenant-stockholder.

     Generally,   rent  and  other  obligations  and  charges  arising  under  a
proprietary  lease or occupancy  agreement which are owed to the Cooperative are
made liens upon the shares to which the proprietary lease or occupancy agreement
relates.  In addition,  the proprietary lease or occupancy  agreement  generally
permits the  Cooperative  to  terminate  the lease or agreement in the event the
borrower  defaults in the performance of covenants  thereunder.  Typically,  the
lender and the Cooperative  enter into a recognition  agreement which,  together
with any lender  protection  provisions  contained in the  proprietary  lease or
occupancy  agreement,  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  the lease or
agreement  until the lender has been provided with notice of and 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 from a sale of the shares and the
proprietary  lease or occupancy  agreement  allocated to the dwelling,  subject,
however,  to the Cooperative's  right to sums due under the proprietary lease or
occupancy  agreement  or which have become  liens on the shares  relating to the
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 amount  realized upon a sale of
the collateral below the outstanding  principal  balance of the Cooperative Loan
and accrued and unpaid interest thereon.

     Recognition  agreements also generally provide that in the event the lender
succeeds to the  tenant-shareholder's  shares and proprietary lease or occupancy
agreement as the result of realizing upon its collateral for a Cooperative Loan,
the lender must obtain the  approval or consent of the board of directors of the
Cooperative  as  required  by the  proprietary  lease  before  transferring  the
Cooperative shares and assigning the proprietary lease. This approval or consent
is usually  based on the  prospective  purchaser's  income and net worth,  among
other factors, and may significantly reduce the number of potential  purchasers,
which could  limit the ability of the lender to sell and realize  upon the value
of the  collateral.  Generally,  the lender is not  limited in any rights it may
have to dispossess the tenant-stockholder.

     Because of the nature of  Cooperative  Loans,  lenders do not  require  the
tenant-stockholder,  i.e., the borrower,  to obtain title insurance of any type.
Consequently,  the existence of any prior liens or other  imperfections of title
affecting the  Cooperative's  building or real estate also may adversely  affect
the  marketability  of the shares allocated to the dwelling unit in the event of
foreclosure.

     A foreclosure on the  Cooperative  shares is accomplished by public sale in
accordance with the provisions of Article 9 of the Uniform  Commercial  Code, or
UCC, and the security agreement  relating to those shares.  Article 9 of the UCC
requires that a sale be conducted in a 'commercially reasonable' manner. Whether
a sale has been conducted in a 'commercially  reasonable'  manner will depend on
the facts in each case. In

                                       60



<PAGE>



<PAGE>

determining commercial reasonableness, a court will look to the notice given the
debtor and the method,  manner,  time,  place and terms of the sale and the sale
price.  Generally, a sale conducted according to the usual practice of creditors
selling  similar  collateral  in the same  area  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 corporation 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.

  Rights of Redemption

     In some states, after sale pursuant to a deed of trust, or a deed to secure
debt or foreclosure of a mortgage, the borrower and foreclosed junior lienors or
other parties are given a statutory period, typically ranging from six months to
two years,  in which to redeem the property from the  foreclosure  sale. In some
states,  redemption may occur only upon payment of the entire principal  balance
of the loan,  accrued  interest and expenses of  foreclosure.  In other  states,
redemption  may be authorized if the former  borrower pays only a portion of the
sums due. In some states,  the right to redeem is an equitable right. The equity
of redemption,  which is a non-statutory right that must be exercised prior to a
foreclosure sale,  should be distinguished  from statutory rights of redemption.
The effect of a statutory  right of redemption is to diminish the ability of the
lender to sell the foreclosed  property.  The rights of redemption  would defeat
the title of any  purchaser  subsequent to  foreclosure  or sale under a deed of
trust or a deed to  secure  debt.  Consequently,  the  practical  effect  of the
redemption  right is to force the lender to maintain  the  property  and pay the
expenses of ownership until the redemption period has expired.

  Anti-Deficiency Legislation and Other Limitations on Lenders

     Some states have imposed statutory prohibitions which limit the remedies of
a beneficiary  under a deed of trust, a mortgagee  under a mortgage or a grantee
under a deed to secure debt.  In some  states,  including  California,  statutes
limit the right of the beneficiary,  mortgagee or grantee to obtain a deficiency
judgment against the borrower following foreclosure.  A deficiency judgment is a
personal  judgment  against  the  former  borrower  equal  in most  cases to the
difference  between  the net amount  realized  upon the public  sale of the real
property  and the  amount  due to the  lender.  In the case of a  mortgage  loan
secured by a property  owned by a trust where the  Mortgage  Note is executed on
behalf  of  the  trust,  a  deficiency  judgment  against  the  trust  following
foreclosure  or sale  under a deed of  trust  or deed to  secure  debt,  even if
obtainable  under  applicable  law, may be of little  value to the  beneficiary,
grantee or mortgagee if there are no trust assets  against which the  deficiency
judgment may be executed.  Some state statutes require the beneficiary,  grantee
or  mortgagee to exhaust the security  afforded  under a deed of trust,  deed to
secure debt or mortgage  by  foreclosure  in an attempt to satisfy the full debt
before bringing a personal action against the borrower.

     In other  states,  the lender has the option of bringing a personal  action
against the borrower on the debt without first exhausting the security; however,
in some of these states, the lender,  following judgment on the personal action,
may be deemed to have  elected a remedy  and may be  precluded  from  exercising
remedies with respect to the security. Consequently, the practical effect of the
election requirement,  in those states permitting this election, is that lenders
will usually  proceed against the security first rather than bringing a personal
action  against the borrower.  Finally,  in other states,  statutory  provisions
limit any deficiency  judgment  against the borrower  following a foreclosure to
the excess of the  outstanding  debt over the fair value of the  property at the
time of the public sale. The purpose of these statutes is generally to prevent a
beneficiary,  grantee or mortgagee  from obtaining a large  deficiency  judgment
against the borrower as a result of low or no bids at the judicial sale.

     Generally,  Article 9 of the UCC governs  foreclosure on Cooperative shares
and the  related  proprietary  lease or  occupancy  agreement.  Some courts have
interpreted  Article  9  to  prohibit  or  limit  a  deficiency  award  in  some
circumstances,  including circumstances where the disposition 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 not conducted in a
commercially reasonable manner.

                                       61



<PAGE>



<PAGE>

     In addition to laws limiting or prohibiting deficiency judgments,  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 collateral and/or
enforce a deficiency  judgment.  For example,  under the federal bankruptcy law,
all actions  against the debtor,  the debtor's  property and any  co-debtor  are
automatically stayed upon the filing of a bankruptcy petition. Moreover, a court
having federal  bankruptcy  jurisdiction may permit a debtor through its Chapter
11 or Chapter 13  rehabilitative  plan to cure a monetary  default relating to a
mortgage loan on the debtor's residence by paying arrearages within a reasonable
time period and reinstating the original  mortgage loan payment  schedule,  even
though  the  lender   accelerated  the  mortgage  loan  and  final  judgment  of
foreclosure  had been entered in state court,  provided no sale of the residence
had yet occurred, prior to the filing of the debtor's petition. Some courts with
federal  bankruptcy  jurisdiction  have approved plans,  based on the particular
facts of the  reorganization  case,  that effected the curing of a mortgage loan
default by paying arrearages over a number of years.

     Courts with federal  bankruptcy  jurisdiction  have also indicated that the
terms  of a  mortgage  loan  secured  by  property  which  is not the  principal
residence of the debtor may be modified. These courts have allowed modifications
that include reducing the amount of each monthly  payment,  changing the rate of
interest,  altering the  repayment  schedule,  forgiving all or a portion of the
debt and reducing the lender's  security interest to the value of the residence,
thus leaving the lender a general unsecured  creditor for the difference between
the value of the residence and the outstanding  balance of the loan.  Generally,
however,  the  terms of a  mortgage  loan  secured  only by a  mortgage  on real
property that is the debtor's  principal  residence may not be modified  under a
plan  confirmed  under  Chapter  13 except  with  respect  to  mortgage  payment
arrearages,  which may be cured  within a reasonable  time  period.  Courts with
federal bankruptcy  jurisdiction  similarly may be able to modify the terms of a
Cooperative Loan.

     Certain tax liens  arising  under the  Internal  Revenue  Code may, in some
circumstances, have priority over the lien of a mortgage, deed to secure debt or
deed of trust.  This may have the effect of  delaying  or  interfering  with the
enforcement of rights with respect to a defaulted mortgage loan.

     In addition,  substantive requirements are imposed upon mortgage lenders in
connection  with the origination and the servicing of mortgage loans by numerous
federal and some state consumer  protection laws. These laws include the federal
Truth-in-Lending  Act,  Real Estate  Settlement  Procedures  Act,  Equal  Credit
Opportunity  Act, Fair Credit Billing Act, Fair Credit Reporting Act and related
statutes.  These federal laws impose specific statutory liabilities upon lenders
who originate  mortgage  loans and who fail to comply with the provisions of the
law. In some cases, this liability may affect assignees of the mortgage loans.

     Some of the mortgage loans may be High Cost Loans.  Purchasers or assignees
of any High Cost Loan,  including any trust,  could be liable for all claims and
subject to all defenses arising under any applicable law that the borrower could
assert against the originator of the High Cost Loan.  Remedies  available to the
borrower  include  monetary  penalties,  as  well  as  recission  rights  if the
appropriate disclosures were not given as required.

  Enforceability of Certain Provisions

     Unless the prospectus  supplement indicates  otherwise,  the mortgage loans
contain due-on-sale  clauses.  These clauses permit the lender to accelerate the
maturity of the loan if the borrower  sells,  transfers or conveys the property.
The  enforceability  of these  clauses  has been the subject of  legislation  or
litigation in many states, and in some cases the enforceability of these clauses
has been limited or denied. However, the Garn-St Germain Depository Institutions
Act of 1982, or Garn-St Germain Act,  preempts state  constitutional,  statutory
and case law that prohibit the  enforcement of  due-on-sale  clauses and permits
lenders to enforce  these  clauses in  accordance  with their terms,  subject to
limited  exceptions.  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.

     The Garn-St Germain Act also sets forth nine specific  instances in which a
mortgage  lender  covered  by  the  Garn-St  Germain  Act  may  not  exercise  a
due-on-sale clause, notwithstanding the fact that a transfer of the property may
have  occurred.  These  include  intra-family  transfers,  certain  transfers by
operation of law,  leases of fewer than three years and the creation of a junior
encumbrance. Regulations promulgated under the Garn-St Germain Act also prohibit
the imposition of a prepayment  penalty upon the  acceleration of a loan under a
due-on-sale clause.

     The inability to enforce a due-on-sale clause may result in a mortgage loan
bearing an interest  rate below the current  market rate being  assumed by a new
home buyer rather than being paid off, which may have an impact upon the average
life of the  mortgage  loans  and the  number  of  mortgage  loans  which may be
outstanding until maturity.

     Upon foreclosure,  courts have imposed general equitable principles.  These
equitable  principles are designed to relieve the borrower from the legal effect
of its defaults  under the loan  documents.  Examples of judicial  remedies that
have been fashioned  include  judicial  requirements  that the lender  undertake
affirmative  and expensive  actions to determine  the causes for the  borrower's
default and the likelihood that the borrower will be able to reinstate the loan.
In some cases,  courts have  required  that  lenders  reinstate  loans or recast
payment  schedules in order to  accommodate  borrowers  who are  suffering  from
temporary financial disability. In other cases, courts have limited the right of
the lender to foreclose  if the default  under the  mortgage  instrument  is not
monetary,  including the borrower  failing to adequately  maintain the property.
Finally, some courts have been faced with the issue of whether or not federal or
state  constitutional  provisions  reflecting due process  concerns for adequate
notice  require  that  borrowers  under deeds of trust,  deeds to secure debt or
mortgages receive notices in addition to the statutorily prescribed minimum. 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,  or under a deed
to  secure  a debt or a  mortgagee  having a power  of  sale,  does not  involve
sufficient state action to afford constitutional protections to the borrower.

  Applicability of Usury Laws

     Title V of the Depository  Institutions  Deregulation  and Monetary Control
Act of 1980, or Title V, provides that state usury  limitations  shall not apply
to some types of residential first mortgage loans,  including Cooperative Loans,
originated by some lenders after March 31, 1980. A similar  federal  statute was
in effect with  respect to mortgage  loans made during the first three months of
1980. The Office of Thrift Supervision, or OTS, is authorized to issue rules and
regulations and to publish interpretations  governing implementation of Title V.
The statute  authorized  any state to impose  interest  rate limits by adopting,
before April 1, 1983, a law or constitutional  provision which expressly rejects
application  of the  federal  law.  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 or to limit  discount
points or other charges.

     Unless  otherwise  described  in the related  prospectus  supplement,  each
seller of a mortgage loan, or another  specified  party,  will have  represented
that each mortgage loan was originated in compliance with then applicable  state
laws,  including  usury laws, in all material  respects.  However,  the mortgage
rates on the  mortgage  loans  will be subject  to  applicable  usury laws as in
effect from time to time.

  Alternative Mortgage Instruments

     Alternative mortgage instruments, including adjustable rate mortgage loans,
adjustable  rate  Cooperative   Loans,  and  early  ownership   mortgage  loans,
originated by non-federally  chartered lenders, have historically been subjected
to a variety of restrictions.  These restrictions  differed from state to state,
resulting  in  difficulties  in  determining  whether a  particular  alternative
mortgage  instrument  originated by a  state-chartered  lender was in compliance
with  applicable law. These  difficulties  were  alleviated  substantially  as a
result of the enactment of Title VIII of the Garn-St Germain Act, or Title VIII.
Title VIII provides that, notwithstanding any state law to the contrary;

      state-chartered  banks may originate  alternative  mortgage instruments in
      accordance with regulations promulgated by the Comptroller of the Currency
      with respect to the  origination  of alternative  mortgage  instruments by
      national banks,

      state-chartered   credit   unions  may  originate   alternative   mortgage
      instruments  in accordance  with  regulations  promulgated by the National
      Credit Union  Administration  with respect to  origination  of alternative
      mortgage instruments by federal credit unions and

      all   other   non-federally   chartered   housing   creditors,   including
      state-chartered  savings and loan  associations,  state-chartered  savings
      banks  and  mutual  savings  banks and  mortgage  banking  companies,  may
      originate   alternative   mortgage  instruments  in  accordance  with  the
      regulations promulgated by the

                                       63

<PAGE>

      Federal  Home Loan Bank Board,  predecessor  to the OTS,  with  respect to
      origination of  alternative  mortgage  instruments by federal  savings and
      loan associations.

Title  VIII  also  provides  that any  state  may  reject  applicability  of the
provisions  of Title VIII by  adopting,  prior to  October  15,  1985,  a law or
constitutional   provision   expressly  rejecting  the  applicability  of  these
provisions. Some states have taken this action.

ENVIRONMENTAL LEGISLATION

     Under the federal Comprehensive  Environmental  Response,  Compensation and
Liability  Act of 1980,  as  amended,  or  CERCLA,  and under  state law in some
states,  a secured party which takes a deed-in-lieu of foreclosure,  purchases a
mortgaged  property at a foreclosure sale, or operates a mortgaged  property may
become  liable in some  circumstances  for the costs of  cleaning  up  hazardous
substances  regardless of whether they have  contaminated  the property.  CERCLA
imposes  strict,  as well as joint and several,  liability on several classes of
potentially  responsible parties,  including current owners and operators of the
property  who did not cause or  contribute  to the  contamination.  Furthermore,
liability  under CERCLA is not limited to the original or unamortized  principal
balance of a loan or to the value of the property  securing a loan.  Lenders may
be held liable under  CERCLA as owners or operators  unless they qualify for the
secured creditor exemption to CERCLA. This exemption exempts from the definition
of owners and operators those who, without  participating in the management of a
facility,  hold indicia of ownership primarily to protect a security interest in
the facility.

     The Asset Conservation, Lender Liability and Deposit Insurance Act of 1996,
or Conservation Act, amended,  among other things, the provisions of CERCLA with
respect to lender liability and the secured creditor exemption. The Conservation
Act offers substantial protection to lenders by defining the activities in which
a  lender  can  engage  and  still  have the  benefit  of the  secured  creditor
exemption.  In order  for a lender  to be  deemed  to have  participated  in the
management of a mortgaged property,  the lender must actually participate in the
operational  affairs of the  property  of the  borrower.  The  Conservation  Act
provides that 'merely having the capacity to influence,  or unexercised right to
control'  operations does not constitute  participation in management.  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.   The
Conservation  Act also  provides that a lender will continue to have the benefit
of the secured creditor exemption even if it forecloses on a mortgaged property,
purchases it at a  foreclosure  sale or accepts a  deed-in-lieu  of  foreclosure
provided  that the lender seeks to sell the  mortgaged  property at the earliest
practicable commercially reasonable time on commercially reasonable terms.

     Other federal and state laws in some  circumstances may impose liability on
a secured party which takes a deed-in-lieu of foreclosure, purchases a mortgaged
property  at a  foreclosure  sale,  or  operates a  mortgaged  property on which
contaminants  other than CERCLA  hazardous  substances  are  present,  including
petroleum,  agricultural  chemicals,  hazardous  wastes,  asbestos,  radon,  and
lead-based  paint.  These cleanup costs may be substantial.  It is possible that
the  cleanup  costs could  become a liability  of a trust and reduce the amounts
otherwise  distributable  to the holders of the related series of  certificates.
Moreover,   some  federal   statutes  and  some  states  by  statute  impose  an
Environmental   Lien.  All  subsequent   liens  on  that  property  are  usually
subordinated to an Environmental  Lien and, in some states,  even prior recorded
liens are  subordinated  to  Environmental  Liens.  In the  latter  states,  the
security  interest of the trustee in a related  parcel of real  property that is
subject to an Environmental Lien could be adversely affected.

     Traditionally,  many  residential  mortgage lenders have not taken steps to
evaluate whether contaminants are present with respect to any mortgaged property
prior  to the  origination  of the  mortgage  loan or prior  to  foreclosure  or
accepting a deed-in-lieu  of  foreclosure.  Neither the depositor nor any master
servicer will be required by any Agreement to undertake any of these evaluations
prior to foreclosure or accepting a deed-in-lieu of  foreclosure.  The depositor
does not make any  representations  or warranties  or assume any liability  with
respect to the absence or effect of  contaminants  on any mortgaged  property or
any casualty resulting from the presence or effect of contaminants. However, the
master servicer will not be obligated to foreclose on any mortgaged  property or
accept a deed-in-lieu  of  foreclosure  if it knows or reasonably  believes that
there are material  contaminated  conditions  on the  property.  A failure so to
foreclose may reduce the amounts otherwise  available to  certificateholders  of
the related series.

                                       64



<PAGE>

     Except as otherwise specified in the applicable prospectus  supplement,  at
the time the mortgage loans were originated,  no  environmental  assessment or a
very limited environment  assessment of the mortgaged  properties will have been
conducted.

SOLDIERS' AND SAILORS' CIVIL RELIEF ACT OF 1940

     Under the terms of the Soldiers' and Sailors'  Civil Relief Act of 1940, as
amended,  or Relief  Act,  a  borrower  who enters  military  service  after the
origination  of the borrower's  mortgage  loan,  including a borrower who was in
reserve  status and is called to active duty after  origination  of the mortgage
loan, may not be charged interest,  including fees and charges,  above an annual
rate of 6% during the period of the  borrower's  active  duty  status,  unless a
court orders otherwise upon application of the lender. The Relief Act applies to
borrowers who are members of the Air Force, Army, Marines, Navy, National Guard,
Reserves or Coast Guard, and officers of the U.S. Public Health Service assigned
to duty with the military.

     Because the Relief Act applies to  borrowers  who enter  military  service,
including  reservists  who are called to active duty,  after  origination of the
related  mortgage  loan,  no  information  can be  provided  as to the number of
mortgage  loans that may be affected by the Relief Act. With respect to mortgage
loans included in a trust, application of the Relief Act would adversely affect,
for an  indeterminate  period of time,  the  ability of the master  servicer  to
collect  full  amounts of interest on those  mortgage  loans.  Any  shortfall in
interest collections resulting from the application of the Relief Act or similar
legislation  or  regulations,  which would not be  recoverable  from the related
mortgage loans, would result in a reduction of the amounts  distributable to the
holders of the related certificates, and would not be covered by Advances or any
form of credit  enhancement  provided in connection  with the related  series of
certificates.  In addition, the Relief Act imposes limitations that would impair
the ability of the master  servicer to  foreclose on an affected  mortgage  loan
during  the  mortgagor's   period  of  active  duty  status,   and,  under  some
circumstances,  during an additional three month period thereafter. Thus, in the
event that the Relief Act or similar  legislation or regulations  applies to any
mortgage loan which goes into default, there may be delays in payment and losses
on  the  related  certificates  in  connection  therewith.  Any  other  interest
shortfalls, deferrals or forgiveness of payments on the mortgage loans resulting
from  similar  legislation  or  regulations  may result in delays in payments or
losses to certificateholders of the related series.

DEFAULT INTEREST AND LIMITATIONS ON PREPAYMENTS

     Notes and  mortgages may contain  provisions  that obligate the borrower to
pay a late charge or additional interest if payments are not timely made, and in
some  circumstances,  may prohibit  prepayments  for a specified  period  and/or
condition  prepayments  upon the borrower's  payment of prepayment fees or yield
maintenance penalties.  In some states, there are or may be specific limitations
upon the late charges which a lender may collect from a borrower for  delinquent
payments.  Some states also limit the amounts  that a lender may collect  from a
borrower  as an  additional  charge if the loan is  prepaid.  In  addition,  the
enforceability  of provisions that provide for prepayment fees or penalties upon
an  involuntary  prepayment  is  unclear  under  the laws of many  states.  Most
conventional  single-family  mortgage  loans may be  prepaid  in full or in part
without  penalty.  The  regulations  of the  Federal  Home Loan Bank  Board,  as
succeeded  by the OTS,  prohibit  the  imposition  of a  prepayment  penalty  or
equivalent fee for or in connection with the  acceleration of a loan by exercise
of a  due-on-sale  clause.  A mortgagee  to whom a  prepayment  in full has been
tendered  may be  compelled  to give  either a  release  of the  mortgage  or an
instrument  assigning  the  existing  mortgage.  The absence of a  restraint  on
prepayment,  particularly  with respect to mortgage loans having higher mortgage
rates, may increase the likelihood of refinancing or other early  retirements of
the mortgage loans.

FORFEITURES IN DRUG AND RICO PROCEEDINGS

     Federal  law  provides  that  property   owned  by  persons   convicted  of
drug-related  crimes or of criminal  violations of the Racketeer  Influenced and
Corrupt  Organizations,  or RICO, statute can be seized by the government if the
property was used in, or purchased  with the  proceeds of, those  crimes.  Under
procedures  contained  in the  Comprehensive  Crime  Control  Act of  1984,  the
government may seize the property even before  conviction.  The government  must
publish notice of the  forfeiture  proceeding and may give notice to all parties
'known to have an alleged  interest in the  property,'  including the holders of
mortgage loans.

                                       65



<PAGE>



<PAGE>

     A lender  may  avoid  forfeiture  of its  interest  in the  property  if it
establishes  that: (i) its mortgage was executed and recorded before  commission
of the crime upon which the forfeiture is based,  or (ii) the lender was, at the
time of execution of the  mortgage,  'reasonably  without cause to believe' that
the  property was used in, or  purchased  with the proceeds of,  illegal drug or
RICO activities.

NEGATIVE AMORTIZATION LOANS

     A recent case held that state  restrictions  on the compounding of interest
are not preempted by the provisions of the Depository Institutions  Deregulation
and Monetary  Control Act of 1980,  or DIDMC,  and as a result,  a mortgage loan
that provided for negative  amortization  violated New  Hampshire's  requirement
that first  mortgage  loans  provide  for  computation  of  interest on a simple
interest basis.  The court did not address the  applicability of the Alternative
Mortgage  Transaction  Parity  Act of 1982,  which  authorizes  a lender to make
residential mortgage loans that provide for negative amortization.  As a result,
the  enforceability  of compound  interest on  mortgage  loans that  provide for
negative  amortization  is  unclear.  The case,  which was  decided by the First
Circuit Court of Appeals,  is binding  authority only on Federal District Courts
in Maine, New Hampshire, Massachusetts, Rhode Island and Puerto Rico.

                    MATERIAL FEDERAL INCOME TAX CONSEQUENCES

GENERAL

     The  following  is  a  discussion  of  the  material   federal  income  tax
consequences  of the purchase,  ownership and  disposition of the  certificates.
This  discussion  is  directed  solely  to  certificateholders   that  hold  the
certificates  as  capital  assets  within the  meaning  of  Section  1221 of the
Internal  Revenue  Code and does not purport to discuss  all federal  income tax
consequences that may be applicable to particular categories of investors,  some
of which,  including banks,  insurance  companies and foreign investors,  may be
subject to special rules. In addition, the authorities on which this discussion,
and the opinion  referred to below, are based are subject to change or differing
interpretations, which could apply retroactively. Taxpayers and preparers of tax
returns,  including  those filed by any REMIC or other  issuer,  should be aware
that under  applicable  Treasury  regulations  a provider  of advice on specific
issues of law is not considered an income tax return  preparer unless the advice
(i) is given with respect to events that have occurred at the time the advice is
rendered  and is not given with  respect  to the  consequences  of  contemplated
actions, and (ii) is directly relevant to the determination of an entry on a tax
return. Accordingly,  taxpayers should consult their tax advisors and tax return
preparers  regarding the preparation of any item on a tax return, even where the
anticipated  tax  treatment  has  been  discussed  in  this  prospectus  or in a
prospectus  supplement.  In  addition  to the  federal  income tax  consequences
described in this prospectus,  potential investors should consider the state and
local tax  consequences,  if any, of the purchase,  ownership and disposition of
the certificates. See 'State and Other Tax Consequences.' Certificateholders are
advised to consult their tax advisors  concerning the federal,  state,  local or
other tax consequences to them of the purchase, ownership and disposition of the
certificates offered hereunder.

     The  following   discussion   addresses  REMIC  certificates   representing
interests  in a trust,  or a portion  thereof,  which the master  servicer  will
covenant to elect to have treated as a REMIC under  Sections  860A through 860G,
or REMIC Provisions, of the Internal Revenue Code. The prospectus supplement for
each series of certificates  will indicate whether a REMIC election or elections
will be made for the  related  trust and, if that  election is to be made,  will
identify all 'regular  interests'  and 'residual  interests' in the REMIC.  If a
REMIC election will not be made for a trust, the federal income  consequences of
the purchase,  ownership and  disposition  of the related  certificates  will be
described  in the  related  prospectus  supplement.  For  purposes  of this  tax
discussion,  references  to a  'certificateholder'  or a  'holder'  are  to  the
beneficial owner of a certificate.

     In the  event  that a REMIC  election  is not made upon the  issuance  of a
particular series because, for example, a grantor trust structure is being used,
an opinion of counsel relating to the tax consequences of that structure will be
filed prior to the initial sale of the related  certificates.  Furthermore,  the
tax  discussion  relating to that  structure  will be provided in the prospectus
supplement for that series.

     The following  discussion is based in part upon the OID  regulations and in
part upon the REMIC regulations.  The OID regulations,  which are effective with
respect to debt instruments  issued on or after April 4, 1994, do not adequately
address some issues relevant to, and in some instances provide that they are not
applicable to, securities similar to the certificates.

REMICS

  Classification of REMICs

     Upon the issuance of each series of REMIC certificates,  Thacher Proffitt &
Wood,  Orrick,  Herrington  &  Sutcliffe  LLP or  Stroock & Stroock & Lavan LLP,
counsel to the  depositor,  will  deliver  their  opinion  to the  effect  that,
assuming  compliance  with all  provisions of the related  pooling and servicing
agreement,  the related trust,  or each  applicable  portion of the trust,  will
qualify as a REMIC and the REMIC certificates  offered with respect thereto will
be  considered  to evidence  ownership of 'regular  interests,'or  REMIC regular
certificates  or 'residual  interests,' or REMIC residual  certificates  in that
REMIC within the meaning of the REMIC Provisions.

     If an entity  electing to be treated as a REMIC fails to comply with one or
more of the ongoing  requirements  of the Internal  Revenue Code for that status
during any taxable year, the Internal Revenue Code provides that the entity will
not be  treated  as a REMIC for that year and  thereafter.  In that  event,  the
entity may be taxable as a separate corporation under Treasury regulations,  and
the related REMIC  certificates  may not be accorded the status or given the tax
treatment  described  in this  prospectus  under  'Material  Federal  Income Tax
Consequences.'  Although  the  Internal  Revenue  Code  authorizes  the Treasury
Department to issue regulations  providing relief in the event of an inadvertent
termination  of REMIC  status,  no  regulations  have been  issued.  Any relief,
moreover,  may be  accompanied  by  sanctions,  including  the  imposition  of a
corporate tax on all or a portion of the trust's  income for the period in which
the  requirements  for that status are not satisfied.  The pooling and servicing
agreement  with  respect to each  REMIC  will  include  provisions  designed  to
maintain  the trust's  status as a REMIC under the REMIC  Provisions.  It is not
anticipated that the status of any trust as a REMIC will be terminated.

  Characterization of Investments in REMIC Certificates

     In general,  the REMIC certificates will be 'real estate assets' within the
meaning  of  Section  856(c)(4)(A)  of the  Internal  Revenue  Code  and  assets
described in Section  7701(a)(19)(C)  of the  Internal  Revenue Code in the same
proportion that the assets of the REMIC underlying the certificates  would be so
treated.  Moreover, if 95% or more of the assets of the REMIC qualify for any of
the  foregoing  treatments  at all  times  during a  calendar  year,  the  REMIC
certificates  will qualify for the  corresponding  status in their  entirety for
that calendar year.  Interest,  including original issue discount,  on the REMIC
regular  certificates  and  income  allocated  to the  class of  REMIC  residual
certificates will be interest described in Section  856(c)(3)(B) of the Internal
Revenue Code to the extent that those  certificates  are treated as 'real estate
assets' within the meaning of Section 856(c)(4)(A) of the Internal Revenue Code.
In addition, the REMIC regular certificates will be 'qualified mortgages' within
the meaning of Section 860G(a)(3)(C) of the Internal Revenue Code if transferred
to  another  REMIC on its  startup  day in  exchange  for  regular  or  residual
interests in that REMIC.  The  determination as to the percentage of the REMIC's
assets  that  constitute  assets  described  in the  foregoing  sections  of the
Internal  Revenue Code will be made with respect to each calendar  quarter based
on the average  adjusted  basis of each category of the assets held by the REMIC
during  that   calendar   quarter.   The  master   servicer  will  report  those
determinations to  certificateholders in the manner and at the times required by
applicable Treasury regulations.

     The  assets of the REMIC will  include,  in  addition  to  mortgage  loans,
payments on mortgage loans held pending  distribution on the REMIC  certificates
and property  acquired by foreclosure held pending sale, and may include amounts
in reserve accounts. It is unclear whether property acquired by foreclosure held
pending sale and amounts in reserve  accounts  would be considered to be part of
the  mortgage  loans,  or whether  those  assets,  to the extent not invested in
assets  described in the foregoing  sections,  otherwise  would receive the same
treatment as the mortgage  loans for purposes of all of the foregoing  sections.
In addition,  in some instances mortgage loans,  including Additional Collateral
Loans or Pledged Asset  Mortgage  Loans,  may not be treated  entirely as assets
described in the foregoing sections. If the assets of a REMIC include Additional
Collateral  Loans  or  Pledged  Asset  Mortgage  Loans,  the  non-real  property
collateral,  while  itself not an asset of the REMIC,  could cause the  mortgage
loans not to  qualify  for one or more of those  characterizations.  If so,  the
related  prospectus  supplement  will  describe  the mortgage  loans,  including
Additional  Collateral Loans or Pledged Asset Mortgage Loans, that may not be so
treated. The REMIC regulations do provide, however, that

                                       67



<PAGE>



<PAGE>

payments on mortgage loans held pending  distribution are considered part of the
mortgage  loans for purposes of Section  856(c)(4)(A)  of the  Internal  Revenue
Code.

  Tiered REMIC Structures

     For some series of REMIC  certificates,  two or more separate elections may
be made to treat designated  portions of the related trust as REMICs for federal
income  tax  purposes.  Upon  the  issuance  of this  type of  series  of  REMIC
certificates,  Thacher  Proffitt & Wood,  Orrick,  Herrington & Sutcliffe LLP or
Stroock & Stroock & Lavan LLP,  counsel to the  depositor,  will  deliver  their
opinion to the effect  that,  assuming  compliance  with all  provisions  of the
related pooling and servicing agreement,  the tiered REMICs will each qualify as
a REMIC and the REMIC  certificates  issued by the tiered REMICs,  respectively,
will be considered to evidence ownership of REMIC regular  certificates or REMIC
residual  certificates  in the  related  REMIC  within the  meaning of the REMIC
Provisions.

     Solely for purposes of determining  whether the REMIC  certificates will be
'real estate assets' within the meaning of Section  856(c)(4)(A) of the Internal
Revenue Code, and 'loans secured by an interest in real property'  under Section
7701(a)(19)(C)  of the  Internal  Revenue  Code,  and  whether the income on the
certificates  is interest  described  in Section  856(c)(3)(B)  of the  Internal
Revenue Code, the tiered REMICs will be treated as one REMIC.

  Taxation of Owners of REMIC Regular Certificates

     General

     Except as otherwise stated in this discussion,  REMIC regular  certificates
will be treated for federal  income tax purposes as debt  instruments  issued by
the REMIC and not as ownership  interests in the REMIC or its assets.  Moreover,
holders of REMIC regular  certificates that otherwise report income under a cash
method of  accounting  will be required to report  income with  respect to REMIC
regular certificates under an accrual method.

     Original Issue Discount

     Some  REMIC  regular  certificates  may  be  issued  with  'original  issue
discount'  within the meaning of Section  1273(a) of the Internal  Revenue Code.
Any holders of REMIC regular  certificates  issued with original  issue discount
typically  will be required to include  original  issue discount in income as it
accrues,  in  accordance  with the  method  described  below,  in advance of the
receipt of the cash attributable to that income. In addition, Section 1272(a)(6)
of the Internal  Revenue Code provides special rules applicable to REMIC regular
certificates  and certain  other debt  instruments  issued with  original  issue
discount. Regulations have not been issued under that section.

     The Internal  Revenue Code  requires  that a prepayment  assumption be used
with  respect to  mortgage  loans held by a REMIC in  computing  the  accrual of
original issue discount on REMIC regular  certificates issued by that REMIC, and
that  adjustments  be made in the amount and rate of accrual of the  discount to
reflect  differences  between  the  actual  prepayment  rate and the  prepayment
assumption. The prepayment assumption is to be determined in a manner prescribed
in Treasury regulations; as noted above, those regulations have not been issued.
The  conference  committee  report  accompanying  the  Tax  Reform  Act of  1986
indicates that the regulations will provide that the prepayment  assumption used
with  respect to a REMIC  regular  certificate  must be the same as that used in
pricing the initial  offering of the REMIC regular  certificate.  The prepayment
assumption used by the master servicer in reporting  original issue discount for
each series of REMIC regular  certificates will be consistent with this standard
and will be disclosed in the related prospectus supplement. However, neither the
depositor nor the master servicer will make any representation that the mortgage
loans will in fact prepay at a rate  conforming to the prepayment  assumption or
at any other rate.

     The original issue discount, if any, on a REMIC regular certificate will be
the excess of its stated  redemption price at maturity over its issue price. The
issue price of a  particular  class of REMIC  regular  certificates  will be the
first cash price at which a substantial amount of REMIC regular  certificates of
that class is sold, excluding sales to bond houses, brokers and underwriters. If

particular  class of REMIC regular  certificates is sold for cash on or prior to
the date of their initial  issuance,  or the closing  date,  the issue price for
that class will be treated as the fair market  value of the class on the closing
date. Under the OID regulations,  the stated redemption price of a REMIC regular
certificate is equal to the total of all payments to be made on that certificate
other than 'qualified  stated  interest.'  Qualified  stated  interest  includes
interest  that is  unconditionally  payable at least  annually at a single fixed
rate,  or in the  case of a  variable  rate  debt  instrument,  at a  'qualified
floating  rate,' an 'objective  rate,' a combination  of a single fixed rate and
one or more 'qualified floating rates' or one 'qualified inverse floating rate,'
or a combination of 'qualified  floating  rates' that generally does not operate
in a manner that  accelerates  or defers  interest  payments on a REMIC  regular
certificate.

     In the case of  REMIC  regular  certificates  bearing  adjustable  interest
rates, the  determination of the total amount of original issue discount and the
timing of the inclusion of the original  issue  discount will vary  according to
the  characteristics  of the REMIC regular  certificates.  If the original issue
discount rules apply to the certificates, the related prospectus supplement will
describe  the manner in which the rules  will be applied by the master  servicer
with  respect to those  certificates  in  preparing  information  returns to the
certificateholders and the Internal Revenue Service, or IRS.

     Some classes of the REMIC  regular  certificates  may provide for the first
interest  payment  with respect to their  certificates  to be made more than one
month after the date of issuance,  a period which is longer than the  subsequent
monthly intervals between interest  payments.  Assuming the 'accrual period' for
original issue discount is each monthly period that ends on a distribution date,
in some cases, as a consequence of this 'long first accrual period,' some or all
interest  payments may be required to be included in the stated redemption price
of the REMIC regular  certificate  and accounted for as original issue discount.
Because  interest on REMIC regular  certificates  must in any event be accounted
for under an accrual  method,  applying  this  analysis  would  result in only a
slight  difference  in the timing of the inclusion in income of the yield on the
REMIC regular certificates.

     In addition,  if the accrued interest to be paid on the first  distribution
date is computed with respect to a period that begins prior to the closing date,
a portion  of the  purchase  price  paid for a REMIC  regular  certificate  will
reflect  the  accrued  interest.  In these  cases,  information  returns  to the
certificateholders and the IRS will be based on the position that the portion of
the purchase  price paid for the interest  accrued with respect to periods prior
to the closing date is treated as part of the overall cost of the REMIC  regular
certificate, and not as a separate asset the cost of which is recovered entirely
out of interest received on the next distribution  date, and that portion of the
interest paid on the first distribution date in excess of interest accrued for a
number of days  corresponding to the number of days from the closing date to the
first distribution date should be included in the stated redemption price of the
REMIC regular  certificate.  However, the OID regulations state that all or some
portion of the accrued  interest may be treated as a separate  asset the cost of
which is recovered entirely out of interest paid on the first distribution date.
It is unclear how an  election to do so would be made under the OID  regulations
and whether that election could be made unilaterally by a certificateholder.

     Notwithstanding the general definition of original issue discount, original
issue  discount  on a REMIC  regular  certificate  will be  considered  to be de
minimis  if it is less than 0.25% of the  stated  redemption  price of the REMIC
regular  certificate  multiplied  by its  weighted  average  maturity.  For this
purpose,  the weighted  average  maturity of the REMIC  regular  certificate  is
computed as the sum of the amounts  determined,  as to each payment  included in
the stated redemption price of the REMIC regular certificate, by multiplying (i)
the number of complete  years,  rounding down for partial years,  from the issue
date until the payment is expected to be made,  presumably  taking into  account
the  prepayment  assumption,  by (ii) a fraction,  the numerator of which is the
amount of the payment,  and the  denominator  of which is the stated  redemption
price at maturity of the REMIC regular  certificate.  Under the OID regulations,
original  issue  discount  of only a de  minimis  amount,  other than de minimis
original issue discount attributable to a so-called 'teaser' interest rate or an
initial interest  holiday,  will be included in income as each payment of stated
principal  is made,  based on the product of the total  amount of the de minimis
original issue discount and a fraction,  the numerator of which is the amount of
the principal  payment and the  denominator of which is the  outstanding  stated
principal  amount of the REMIC regular  certificate.  The OID  regulations  also
would permit a  certificateholder  to elect to accrue de minimis  original issue
discount into income currently based on a constant yield method. See ' -- Market
Discount' for a description of that election under the OID regulations.

     If original issue discount on a REMIC regular certificate is in excess of a
de minimis amount,  the holder of the certificate must include in ordinary gross
income the sum of the 'daily  portions' of original  issue discount for each day
during  its  taxable  year on  which  it held  the  REMIC  regular  certificate,
including the purchase date but excluding the  disposition  date. In the case of
an  original  holder  of a REMIC  regular  certificate,  the daily  portions  of
original issue discount will be determined as follows.

     As to each  'accrual  period,'  that is,  unless  otherwise  stated  in the
related prospectus supplement,  each period that ends on a date that corresponds
to a  distribution  date and begins on the first day following  the  immediately
preceding accrual period, or in the case of the first accrual period,  begins on
the closing  date,  a  calculation  will be made of the portion of the  original
issue discount that accrued during that accrual period.  The portion of original
issue discount that accrues in any accrual period will equal the excess, if any,
of (i) the sum of (A) the present value, as of the end of the accrual period, of
all of the distributions  remaining to be made on the REMIC regular certificate,
if any, in future  periods and (B) the  distributions  made on the REMIC regular
certificate  during  the  accrual  period  of  amounts  included  in the  stated
redemption  price,  over (ii) the  adjusted  issue  price of the  REMIC  regular
certificate  at the  beginning of the accrual  period.  The present value of the
remaining distributions referred to in the preceding sentence will be calculated
(1)  assuming  that  distributions  on the  REMIC  regular  certificate  will be
received in future  periods based on the mortgage  loans being prepaid at a rate
equal to the  prepayment  assumption  and (2) using a discount rate equal to the
original yield to maturity of the certificate.  For these purposes, the original
yield to maturity of the certificate will be calculated based on its issue price
and assuming that  distributions  on the certificate will be made in all accrual
periods  based  on the  mortgage  loans  being  prepaid  at a rate  equal to the
prepayment  assumption.  The adjusted issue price of a REMIC regular certificate
at the  beginning  of any  accrual  period  will  equal the  issue  price of the
certificate,  increased by the aggregate  amount of original issue discount that
accrued with respect to that certificate in prior accrual  periods,  and reduced
by the amount of any  distributions  made on that REMIC regular  certificate  in
prior accrual periods of amounts  included in its stated  redemption  price. The
original  issue  discount  accruing  during  any  accrual  period,  computed  as
described above, will be allocated ratably to each day during the accrual period
to determine the daily portion of original issue discount for that day.

     The OID  regulations  suggest that original  issue discount with respect to
securities that represent multiple  uncertificated  REMIC regular interests,  in
which ownership  interests will be issued  simultaneously  to the same buyer and
which may be required  under the related  pooling and servicing  agreement to be
transferred together,  should be computed on an aggregate method. In the absence
of further  guidance  from the IRS,  original  issue  discount  with  respect to
securities that represent the ownership of multiple uncertificated REMIC regular
interests will be reported to the IRS and the certificateholders on an aggregate
method based on a single overall  constant  yield and the prepayment  assumption
stated in the related prospectus supplement, treating all uncertificated regular
interests as a single debt  instrument as set forth in the OID  regulations,  so
long as the pooling and servicing  agreement  requires  that the  uncertificated
regular interests be transferred together.

     A subsequent  purchaser of a REMIC regular  certificate  that purchases the
certificate  at a cost,  excluding  any  portion  of that cost  attributable  to
accrued  qualified  stated interest,  less than its remaining stated  redemption
price will also be required to include in gross income the daily portions of any
original issue discount with respect to that  certificate.  However,  each daily
portion will be reduced, if the cost is in excess of its 'adjusted issue price,'
in  proportion to the ratio that excess bears to the  aggregate  original  issue
discount remaining to be accrued on the REMIC regular certificate.  The adjusted
issue  price of a REMIC  regular  certificate  on any given day  equals  (i) the
adjusted  issue  price or, in the case of the first  accrual  period,  the issue
price,  of the certificate at the beginning of the accrual period which includes
that day, plus (ii) the daily  portions of original  issue discount for all days
during the accrual  period prior to that day minus (iii) any principal  payments
made  during  the  accrual  period  prior  to  that  day  with  respect  to  the
certificate.

     Market Discount

     A certificateholder  that purchases a REMIC regular certificate at a market
discount,  that is, in the case of a REMIC regular  certificate  issued  without
original  issue  discount,  at a purchase  price less than its remaining  stated
principal  amount,  or in the case of a REMIC  regular  certificate  issued with
original issue discount,  at a purchase price less than its adjusted issue price
will  recognize  income upon receipt of each  distribution  representing  stated
redemption price. In particular, under Section 1276 of the Internal Revenue Code
such a  certificateholder  generally will be required to allocate the portion of
each distribution representing stated

                                       70



<PAGE>



<PAGE>

redemption  price first to accrued market  discount not  previously  included in
income, and to recognize ordinary income to that extent.

     A  certificateholder  may  elect  to  include  market  discount  in  income
currently  as it  accrues  rather  than  including  it on a  deferred  basis  in
accordance  with the  foregoing.  If made, the election will apply to all market
discount  bonds acquired by the  certificateholder  on or after the first day of
the first  taxable year to which the  election  applies.  In  addition,  the OID
regulations  permit  a  certificateholder  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. If the election were made
with  respect  to  a  REMIC  regular  certificate  with  market  discount,   the
certificateholder  would be deemed to have made an election to include currently
market  discount in income  with  respect to all other debt  instruments  having
market discount that the  certificateholder  acquires during the taxable year of
the  election  or  thereafter.  Similarly,  a  certificateholder  that made this
election for a certificate that is acquired at a premium would be deemed to have
made an election to amortize  bond premium with respect to all debt  instruments
having amortizable bond premium that the certificateholder owns or acquires. See
' -- Premium.' Each of these elections to accrue interest,  discount and premium
with respect to a certificate  on a constant yield method or as interest may not
be revoked without the consent of the IRS.

     However,  market discount with respect to a REMIC regular  certificate will
be  considered  to be de minimis for  purposes of Section  1276 of the  Internal
Revenue Code if the market  discount is less than 0.25% of the remaining  stated
redemption  price of the REMIC regular  certificate  multiplied by the number of
complete  years  to  maturity  remaining  after  the  date of its  purchase.  In
interpreting  a  similar  rule  with  respect  to  original  issue  discount  on
obligations  payable in installments,  the OID regulations refer to the weighted
average  maturity  of  obligations,  and it is likely that the same rule will be
applied  with  respect to market  discount,  presumably  taking into account the
prepayment  assumption.  If market  discount is treated as de minimis under this
rule, it appears that the actual  discount  would be treated in a manner similar
to original  issue  discount  of a de minimis  amount.  See ' -- Original  Issue
Discount.'  This  treatment may 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 above.

     Section 1276(b)(3) of the Internal Revenue Code specifically authorizes the
Treasury  Department to issue regulations  providing for the method for accruing
market discount on debt  instruments,  the principal of which is payable in more
than one installment.  Until regulations are issued by the Treasury  Department,
certain rules  described in the Committee  Report  apply.  The Committee  Report
indicates  that  in  each  accrual  period  market  discount  on  REMIC  regular
certificates should accrue, at the certificateholder's option:

      on the basis of a constant yield method,

      in the case of a REMIC regular  certificate  issued without original issue
      discount,  in an amount  that bears the same ratio to the total  remaining
      market discount as the stated interest paid in the accrual period bears to
      the  total  amount of stated  interest  remaining  to be paid on the REMIC
      regular certificate as of the beginning of the accrual period, or

      in the case of a REMIC  regular  certificate  issued with  original  issue
      discount,  in an amount  that bears the same ratio to the total  remaining
      market  discount as the  original  issue  discount  accrued in the accrual
      period bears to the total original  issue discount  remaining on the REMIC
      regular certificate at the beginning of the accrual period.

Moreover,  the prepayment assumption used in calculating the accrual of original
issue  discount is to be used in  calculating  the  accrual of market  discount.
Because the regulations  referred to in this paragraph have not been issued,  it
is not possible to predict what effect those  regulations  might have on the tax
treatment  of a  REMIC  regular  certificate  purchased  at a  discount  in  the
secondary market.

     To the extent that REMIC regular  certificates provide for monthly or other
periodic  distributions  throughout their term, the effect of these rules may be
to require  market  discount  to be  includible  in income at a rate that is not
significantly slower than the rate at which the discount would accrue if it were
original  issue  discount.  Moreover,  in any event a holder of a REMIC  regular
certificate  generally  will be  required  to treat a portion of any gain on the
sale or exchange  of that  Certificate  as ordinary  income to the extent of the
market  discount  accrued to the date of disposition  under one of the foregoing
methods,  less any  accrued  market  discount  previously  reported  as ordinary
income.

     In addition, under Section 1277 of the Internal Revenue Code, a holder of a
REMIC  regular  certificate  may be required to defer a portion of its  interest
deductions for the taxable year attributable to any indebtedness

                                       71



<PAGE>



<PAGE>

incurred or continued to purchase or carry a REMIC regular certificate purchased
with market discount.  For these purposes, the de minimis rule referred to above
applies. Any deferred interest expense would not exceed the market discount that
accrues during that taxable year and is, in general,  allowed as a deduction not
later than the year in which the market discount is includible in income. If the
holder elects to include  market  discount in income  currently as it accrues on
all market discount  instruments acquired by that holder in that taxable year or
thereafter, the interest deferral rule described above will not apply.

     Premium

     A REMIC regular certificate  purchased at a cost,  excluding any portion of
that cost  attributable to accrued  qualified stated interest,  greater than its
remaining  stated  redemption  price will be  considered  to be  purchased  at a
premium.  The holder of a REMIC regular  certificate may elect under Section 171
of the Internal  Revenue Code to amortize that premium under the constant  yield
method over the life of the  certificate.  If made,  this election will apply to
all debt  instruments  having  amortizable  bond premium that the holder owns or
subsequently  acquires.  Amortizable  premium  will be  treated  as an offset to
interest  income on the  related  REMIC  regular  certificate,  rather than as a
separate interest deduction. The OID regulations also permit  certificateholders
to elect to include all  interest,  discount  and  premium in income  based on a
constant yield method, further treating the certificateholder as having made the
election  to  amortize  premium  generally.  See  '  --  Market  Discount.'  The
conference  committee report states that the same rules that apply to accrual of
market  discount,  which rules will  require use of a prepayment  assumption  in
accruing  market  discount  with respect to REMIC regular  certificates  without
regard to whether those  certificates  have original issue  discount,  will also
apply in amortizing bond premium under Section 171 of the Internal Revenue Code.

     Realized Losses

     Under Section 166 of the Internal  Revenue Code, both corporate  holders of
the REMIC regular  certificates  and  noncorporate  holders of the REMIC regular
certificates  that acquire  those  certificates  in  connection  with a trade or
business should be allowed to deduct,  as ordinary losses,  any losses sustained
during a taxable  year in which their  certificates  become  wholly or partially
worthless as the result of one or more  Realized  Losses on the mortgage  loans.
However,  it appears  that a  noncorporate  holder that does not acquire a REMIC
regular  certificate in connection with a trade or business will not be entitled
to deduct a loss  under  Section  166 of the  Internal  Revenue  Code  until the
holder's certificate becomes wholly worthless -- until its outstanding principal
balance has been reduced to zero -- and that the loss will be characterized as a
short-term capital loss.

     Each  holder of a REMIC  regular  certificate  will be  required  to accrue
interest and original issue discount with respect to that  certificate,  without
giving effect to any  reductions in  distributions  attributable  to defaults or
delinquencies on the mortgage loans or the underlying  certificates until it can
be  established  that any reduction  ultimately  will not be  recoverable.  As a
result,  the amount of taxable income  reported in any period by the holder of a
REMIC regular  certificate  could exceed the amount of economic  income actually
realized by the holder in that period.  Although  the holder of a REMIC  regular
certificate eventually will recognize a loss or reduction in income attributable
to  previously  accrued and included  income  that,  as the result of a Realized
Loss,  ultimately  will not be realized,  the law is unclear with respect to the
timing and character of the loss or reduction in income.

  Taxation of Owners of REMIC Residual Certificates

     General

     As residual interests,  the REMIC residual  certificates will be subject to
tax rules that  differ  significantly  from those that would  apply if the REMIC
residual  certificates  were  treated for federal  income tax purposes as direct
ownership  interests in the mortgage loans or as debt instruments  issued by the
REMIC.

     A holder of a REMIC  residual  certificate  generally  will be  required to
report  its daily  portion of the  taxable  income  or, in  accordance  with the
limitations  noted in this  discussion,  the net loss of the  REMIC for each day
during a calendar quarter that the holder owned the REMIC residual  certificate.
For this purpose,  the taxable income or net loss of the REMIC will be allocated
to each day in the calendar  quarter  ratably using a '30 days per month/90 days
per quarter/360  days per year'  convention  unless  otherwise  disclosed in the
related

                                       72

<PAGE>

prospectus supplement.  The daily amounts will then be allocated among the REMIC
residual   certificateholders   in  proportion  to  their  respective  ownership
interests on that day.  Any amount  included in the gross income or allowed as a
loss of any REMIC residual  certificateholder  by virtue of this allocation will
be treated as ordinary  income or loss.  The taxable income of the REMIC will be
determined  under the rules  described in this prospectus in ' -- Taxable Income
of the  REMIC'  and will be  taxable  to the REMIC  residual  certificateholders
without  regard to the  timing or amount  of cash  distributions  by the  REMIC.
Ordinary  income  derived from REMIC  residual  certificates  will be 'portfolio
income' for purposes of the taxation of taxpayers in accordance with limitations
under Section 469 of the Internal Revenue Code on the  deductibility of 'passive
losses.'

     A holder of a REMIC residual  certificate  that  purchased the  certificate
from a prior holder of that  certificate  also will be required to report on its
federal income tax return amounts  representing its daily portion of the taxable
income or net loss of the  REMIC  for each day that it holds the REMIC  residual
certificate.  These daily  portions  generally will equal the amounts of taxable
income or net loss determined as described above. The committee report indicates
that modifications of the general rules may be made, by regulations, legislation
or otherwise,  to reduce,  or increase,  the income or loss of a REMIC  residual
certificateholder  that  purchased the REMIC residual  certificate  from a prior
holder of such  certificate  at a price greater than, or less than, the adjusted
basis, as defined below,  that REMIC residual  certificate would have had in the
hands of an original holder of that Certificate. The REMIC regulations, however,
do not provide for any such modifications.

     Any payments received by a REMIC residual  certificateholder  in connection
with the  acquisition  of that  REMIC  residual  certificate  will be taken into
account in determining the income of the holder for federal income tax purposes.
Although  it appears  likely  that any  payment  would be  includible  in income
immediately  upon its receipt,  the IRS might assert that the payment  should be
included in income over time according to an amortization  schedule or according
to some other method.  Because of the  uncertainty  concerning  the treatment of
these payments,  holders of REMIC residual certificates should consult their tax
advisors concerning the treatment of these payments for income tax purposes.

     The amount of income REMIC residual  certificateholders will be required to
report, or the tax liability  associated with that income, may exceed the amount
of cash  distributions  received  from the REMIC for the  corresponding  period.
Consequently,  REMIC  residual  certificateholders  should have other sources of
funds  sufficient  to pay any  federal  income  taxes  due as a result  of their
ownership of REMIC residual  certificates or unrelated  deductions against which
income may be offset,  subject to the rules relating to 'excess  inclusions' and
'noneconomic'  residual  interests  discussed  below.  The  fact  that  the  tax
liability   associated   with   the   income   allocated   to   REMIC   residual
certificateholders  may  exceed  the cash  distributions  received  by the REMIC
residual  certificateholders  for the  corresponding  period  may  significantly
adversely affect the REMIC residual certificateholders after-tax rate of return.

  Taxable Income of the REMIC

     The  taxable  income of the REMIC will equal the income  from the  mortgage
loans and other assets of the REMIC plus any cancellation of indebtedness income
due to the allocation of Realized Losses to REMIC regular certificates, less the
deductions allowed to the REMIC for interest,  including original issue discount
and reduced by the  amortization  of any premium  received on  issuance,  on the
REMIC  regular   certificates,   and  any  other  class  of  REMIC  certificates
constituting  'regular interests' in the REMIC not offered hereby,  amortization
of any premium on the mortgage  loans,  bad debt  deductions with respect to the
mortgage loans and, except as described below, for servicing, administrative and
other expenses.

     For  purposes of  determining  its taxable  income,  the REMIC will have an
initial  aggregate  basis  in its  assets  equal  to  their  fair  market  value
immediately  after their  transfer to the REMIC.  For this  purpose,  the master
servicer  intends to treat the fair market value of the mortgage  loans as being
equal to the aggregate issue prices of the REMIC regular  certificates and REMIC
residual certificates.  The aggregate basis will be allocated among the mortgage
loans  collectively  and the other  assets of the REMIC in  proportion  to their
respective fair market values. The issue price of any REMIC certificates offered
hereby will be determined in the manner  described  above under ' -- Taxation of
Owners of REMIC Regular  Certificates -- Original Issue Discount.'  Accordingly,
if one or more classes of REMIC  certificates are retained initially rather than
sold,  the master  servicer may be required to estimate the fair market value of
those  interests  in order to  determine  the basis of the REMIC in the mortgage
loans and other property held by the REMIC.

                                       73

<PAGE>

     Subject to the possible  application of the de minimis rules, the method of
accrual by the REMIC of  original  issue  discount  income  and market  discount
income with respect to mortgage  loans that it holds will be  equivalent  to the
method  of  accruing   original   issue   discount   income  for  REMIC  regular
certificateholders  -- under the constant  yield method  taking into account the
prepayment assumption. However, a REMIC that acquires loans at a market discount
must  include the  discount in income  currently,  as it accrues,  on a constant
interest  basis.  See ' --  Taxation  of Owners of REMIC  Regular  Certificates'
above, which describes a method of accruing discount income that is analogous to
that  required to be used by a REMIC as to mortgage  loans with market  discount
that it holds.

     A  mortgage  loan will be deemed to have been  acquired  with  discount  or
premium to the extent that the REMIC's basis therein, determined as described in
the  preceding  paragraph,  is less than or greater  than its stated  redemption
price. Any discount will be includible in the income of the REMIC as it accrues,
in advance of receipt of the cash  attributable  to that income,  under a method
similar to the method  described  above for accruing  original issue discount on
the REMIC regular  certificates.  It is  anticipated  that each REMIC will elect
under  Section 171 of the  Internal  Revenue Code to amortize any premium on the
mortgage loans.  Premium on any mortgage loan to which the election  applies may
be amortized  under a constant  yield method,  presumably  taking into account a
prepayment assumption.

     A REMIC will be allowed  deductions for interest,  including original issue
discount, on the REMIC regular certificates,  including any other class of REMIC
certificates  constituting  'regular interests' in the REMIC not offered hereby,
equal to the deductions that would be allowed if the REMIC regular certificates,
including any other class of REMIC certificates constituting 'regular interests'
in the REMIC not offered hereby, were indebtedness of the REMIC.  Original issue
discount will be considered to accrue for this purpose as described  above under
' --  Taxation  of  Owners  of REMIC  Regular  Certificates  --  Original  Issue
Discount,'  except that the de minimis rule and the  adjustments  for subsequent
holders of REMIC regular certificates, including any other class of certificates
constituting  'regular  interests'  in the REMIC not offered  hereby,  described
therein will not apply.

     If a class of REMIC regular certificates is issued at an Issue Premium, the
net amount of interest  deductions  that are  allowed the REMIC in each  taxable
year with  respect  to the REMIC  regular  certificates  of that  class  will be
reduced  by an  amount  equal  to the  portion  of the  Issue  Premium  that  is
considered  to be amortized  or repaid in that year.  Although the matter is not
entirely  certain,  it is likely that Issue Premium  would be amortized  under a
constant yield method in a manner  analogous to the method of accruing  original
issue  discount  described  above under ' -- Taxation of Owners of REMIC Regular
Certificates -- Original Issue Discount.'

     As a general  rule,  the taxable  income of the REMIC will be determined in
the same manner as if the REMIC were an  individual  having the calendar year as
its taxable year and using the accrual method of accounting. However, no item of
income,  gain, loss or deduction  allocable to a prohibited  transaction will be
taken into account.  See ' -- Prohibited  Transactions  and Other Possible REMIC
Taxes' below.  Further,  the  limitation on  miscellaneous  itemized  deductions
imposed on individuals by Section 67 of the Internal  Revenue Code, which allows
those  deductions only to the extent they exceed in the aggregate two percent of
the taxpayer's  adjusted gross income, will not be applied at the REMIC level so
that the REMIC will be allowed  deductions  for  servicing,  administrative  and
other  non-interest  expenses in determining  its taxable  income.  All of these
expenses will be allocated as a separate  item to the holders of REMIC  residual
certificates,  subject to the  limitation of Section 67 of the Internal  Revenue
Code. See ' -- Possible  Pass-Through of Miscellaneous  Itemized Deductions.' If
the  deductions  allowed  to the REMIC  exceed  its gross  income for a calendar
quarter,  the  excess  will be the net loss  for the  REMIC  for  that  calendar
quarter.

  Basis Rules, Net Losses and Distributions

     The adjusted  basis of a REMIC  residual  certificate  will be equal to the
amount paid for that REMIC residual  certificate,  increased by amounts included
in the income of the  related  certificateholder  and  decreased,  but not below
zero,  by  distributions  made,  and by net  losses  allocated,  to the  related
certificateholder.

     A REMIC residual  certificateholder is not allowed to take into account any
net loss for any  calendar  quarter to the extent the net loss exceeds the REMIC
residual certificateholder's adjusted basis in its REMIC residual certificate as
of the close of that  calendar  quarter,  determined  without  regard to the net
loss. Any loss that is not currently deductible by reason of this limitation may
be carried forward indefinitely to future calendar quarters

                                       74

and, in accordance with the same  limitation,  may be used only to offset income
from  the  REMIC   residual   certificate.   The   ability  of  REMIC   residual
certificateholders   to  deduct  net  losses  in  accordance   with   additional
limitations under the Internal Revenue Code, as to which the  certificateholders
should consult their tax advisors.

     Any  distribution  on a REMIC  residual  certificate  will be  treated as a
non-taxable  return of capital  to the  extent it does not  exceed the  holder's
adjusted basis in the REMIC residual  certificate.  To the extent a distribution
on a REMIC residual  certificate  exceeds the adjusted basis, it will be treated
as gain  from the  sale of the  REMIC  residual  certificate.  Holders  of REMIC
residual  certificates may be entitled to distributions early in the term of the
related  REMIC under  circumstances  in which their bases in the REMIC  residual
certificates will not be sufficiently  large that  distributions will be treated
as nontaxable returns of capital. Their bases in the REMIC residual certificates
will initially  equal the amount paid for such REMIC residual  certificates  and
will be  increased  by their  allocable  shares of taxable  income of the trust.
However,  their  basis  increases  may not occur  until the end of the  calendar
quarter,  or perhaps the end of the  calendar  year,  with  respect to which the
REMIC taxable income is allocated to the REMIC residual  certificateholders.  To
the extent the REMIC residual certificateholders initial bases are less than the
distributions  to the REMIC  residual  certificateholders,  and increases in the
initial bases either occur after  distributions  or, together with their initial
bases, are less than the amount of the distributions, gain will be recognized to
the REMIC residual certificateholders on those distributions and will be treated
as gain from the sale of their REMIC residual certificates.

     The effect of these rules is that a certificateholder  may not amortize its
basis in a REMIC  residual  certificate,  but may only recover its basis through
distributions, through the deduction of its share of any net losses of the REMIC
or upon  the sale of its  REMIC  residual  certificate.  See ' -- Sales of REMIC
Certificates.'  For a discussion of possible  modifications  of these rules that
may require  adjustments to income of a holder of a REMIC  residual  certificate
other than an  original  holder in order to reflect any  difference  between the
cost of the REMIC residual  certificate to its holder and the adjusted basis the
REMIC residual  certificate  would have had in the hands of the original holder,
see ' -- General.'

     Excess Inclusions

     Any 'excess  inclusions' with respect to a REMIC residual  certificate will
be subject to federal income tax in all events.

     In  general,  the  'excess  inclusions'  with  respect to a REMIC  residual
certificate for any calendar quarter will be the excess,  if any, of (i) the sum
of the daily  portions of REMIC taxable  income  allocable to the REMIC residual
certificate  over (ii) the sum of the 'daily  accruals',  as defined below,  for
each day during that quarter that the REMIC residual certificate was held by the
REMIC  residual  certificateholder.  The  daily  accruals  of a  REMIC  residual
certificateholder will be determined by allocating to each day during a calendar
quarter its ratable  portion of the product of the 'adjusted issue price' of the
REMIC residual  certificate at the beginning of the calendar quarter and 120% of
the  'long-term  Federal rate' in effect on the closing date.  For this purpose,
the adjusted issue price of a REMIC residual  certificate as of the beginning of
any  calendar  quarter  will be equal to the issue  price of the REMIC  residual
certificate,  increased by the sum of the daily  accruals for all prior quarters
and decreased, but not below zero, by any distributions made with respect to the
REMIC residual certificate before the beginning of that quarter. The issue price
of a REMIC  residual  certificate  is the initial  offering price to the public,
excluding bond houses,  brokers and underwriters,  at which a substantial amount
of the REMIC residual  certificates were sold. If less than a substantial amount
of a  particular  class of REMIC  residual  certificates  is sold for cash on or
prior to the closing date,  the issue price of that class will be treated as the
fair market  value of that class on the closing  date.  The  'long-term  Federal
rate' is an average of current  yields on Treasury  securities  with a remaining
term of greater than nine years, computed and published monthly by the IRS.

     For REMIC residual certificateholders, an excess inclusion:

      will not be permitted to be offset by deductions, losses or loss
      carryovers from other activities,

      will be treated as 'unrelated business taxable income' to an otherwise
      tax-exempt organization and

      will not be  eligible  for any  rate  reduction  or  exemption  under  any
      applicable  tax treaty with respect to the 30% United  States  withholding
      tax imposed on distributions to REMIC residual certificateholders that are
      foreign investors.

                                       75



<PAGE>



<PAGE>

See, however, ' -- Foreign Investors in REMIC Certificates.'

     Furthermore,  for  purposes  of the  alternative  minimum  tax,  (i) excess
inclusions  will  not be  permitted  to be  offset  by the  alternative  tax net
operating loss deduction and (ii) alternative  minimum taxable income may not be
less than the taxpayer's excess inclusions; provided, however, that for purposes
of (ii),  alternative minimum taxable income is determined without regard to the
special  rule that taxable  income  cannot be less than excess  inclusions.  The
latter rule has the effect of preventing nonrefundable tax credits from reducing
the taxpayer's income tax to an amount lower than the alternative minimum tax on
excess inclusions.

     In the  case of any  REMIC  residual  certificates  held  by a real  estate
investment  trust,  the aggregate  excess  inclusions  with respect to the REMIC
residual  certificates,  reduced,  but  not  below  zero,  by  the  real  estate
investment trust taxable income,  within the meaning of Section 857(b)(2) of the
Internal  Revenue Code,  excluding any net capital gain, will be allocated among
the  shareholders  of the trust in proportion  to the dividends  received by the
shareholders  from the trust,  and any amount so allocated will be treated as an
excess  inclusion  with  respect  to a  REMIC  residual  certificate  as if held
directly by the shareholder. Treasury regulations yet to be issued could apply a
similar  rule to  regulated  investment  companies,  common trust funds and some
cooperatives; the REMIC regulations currently do not address this subject.

     Noneconomic REMIC Residual Certificates

     Under the REMIC  regulations,  transfers of  'noneconomic'  REMIC  residual
certificates  will be  disregarded  for all  federal  income tax  purposes if 'a
significant  purpose of the transfer was to enable the  transferor to impede the
assessment or collection of tax.' If the transfer is disregarded,  the purported
transferor  will continue to remain liable for any taxes due with respect to the
income on the 'noneconomic'  REMIC residual  certificate.  The REMIC regulations
provide that a REMIC residual  certificate is noneconomic  unless,  based on the
prepayment  assumption  and on any  required  or  permitted  clean up calls,  or
required  qualified  liquidation  provided  for  in the  REMIC's  organizational
documents,   (1)  the  present  value  of  the  expected  future   distributions
(discounted using the 'applicable  Federal rate' for obligations whose term ends
on the close of the last  quarter in which  excess  inclusions  are  expected to
accrue with respect to the REMIC  residual  certificate,  which rate is computed
and published  monthly by the IRS, on the REMIC residual  certificate  equals at
least  the  present  value  of  the  expected  tax  on  the  anticipated  excess
inclusions,  and (2) the transferor  reasonably expects that the transferee will
receive distributions with respect to the REMIC residual certificate at or after
the time the taxes  accrue on the  anticipated  excess  inclusions  in an amount
sufficient  to satisfy the accrued  taxes.  Accordingly,  all transfers of REMIC
residual certificates that may constitute noneconomic residual interests will be
subject to  restrictions  under the terms of the related  pooling and  servicing
agreement  that are intended to reduce the  possibility  of any  transfer  being
disregarded.  The restrictions  will require each party to a transfer to provide
an  affidavit  that no purpose of the  transfer is to impede the  assessment  or
collection of tax, including  representations  as to the financial  condition of
the prospective transferee,  as to which the transferor also is required to make
a reasonable investigation to determine the transferee's historic payment of its
debts and  ability to  continue to pay its debts as they come due in the future.
Prior to purchasing a REMIC residual certificate,  prospective purchasers should
consider  the  possibility  that a  purported  transfer  of the  REMIC  residual
certificate by such a purchaser to another  purchaser at some future date may be
disregarded in accordance with the  above-described  rules which would result in
the retention of tax liability by that purchaser.

     The related  prospectus  supplement  will  disclose  whether  offered REMIC
residual certificates may be considered  'noneconomic'  residual interests under
the REMIC regulations. Any disclosure that a REMIC residual certificate will not
be  considered  'noneconomic'  will be  based  upon  some  assumptions,  and the
depositor will make no representation that a REMIC residual certificate will not
be considered  'noneconomic' for purposes of the above-described rules. See ' --
Foreign Investors in REMIC Certificates' for additional  restrictions applicable
to transfers of certain REMIC residual certificates to foreign persons.

     Mark-to-Market Rules

     The mark-to-market requirement applies to all securities owned by a dealer,
except to the extent that the dealer has  specifically  identified a security as
held for investment. The Mark-to-Market Regulations provide that for purposes of
this mark-to-market  requirement,  a REMIC residual  certificate  acquired on or
after January 4, 1995 is not treated as a security and thus may not be marked to
market. Prospective purchasers of a REMIC

                                       76



<PAGE>



<PAGE>

residual  certificate  should consult their tax advisors  regarding the possible
application of the mark-to-market requirement to REMIC residual certificates.

     Possible Pass-Through of Miscellaneous Itemized Deductions

     Fees and expenses of a REMIC  generally will be allocated to the holders of
the related REMIC residual  certificates.  The applicable  Treasury  regulations
indicate, however, that in the case of a REMIC that is similar to a single class
grantor trust,  all or a portion of those fees and expenses  should be allocated
to the holders of the  related  REMIC  regular  certificates.  Unless  otherwise
stated in the related prospectus supplement, fees and expenses will be allocated
to holders of the related REMIC residual  certificates in their entirety and not
to the holders of the related REMIC regular certificates.

     With respect to REMIC residual  certificates or REMIC regular  certificates
the holders of which  receive an  allocation  of fees and expenses in accordance
with the preceding discussion, if any holder thereof is an individual, estate or
trust, or a 'Pass-Through Entity' beneficially owned by one or more individuals,
estates or trusts, (i) an amount equal to the individual's,  estate's or trust's
share of fees and expenses  will be added to the gross income of that holder and
(ii) the  individual's,  estate's or trust's  share of fees and expenses will be
treated as a miscellaneous  itemized deduction  allowable in accordance with the
limitation  of Section 67 of the Internal  Revenue  Code,  which  permits  those
deductions  only to the extent  they  exceed in the  aggregate  two percent of a
taxpayer's  adjusted  gross  income.  In  addition,  Section 68 of the  Internal
Revenue Code provides that the amount of itemized deductions otherwise allowable
for an individual whose adjusted gross income exceeds a specified amount will be
reduced by the lesser of (i) 3% of the excess of the individual's adjusted gross
income  over  that  amount  or (ii) 80% of the  amount  of  itemized  deductions
otherwise  allowable  for the taxable  year.  The amount of  additional  taxable
income  reportable by REMIC  certificateholders  that are in accordance with the
limitations of either Section 67 or Section 68 of the Internal  Revenue Code may
be substantial.  Furthermore,  in determining  the  alternative  minimum taxable
income of such a holder of a REMIC Certificate that is an individual,  estate or
trust, or a 'Pass-Through Entity' beneficially owned by one or more individuals,
estates or trusts,  no  deduction  will be allowed for such  holder's  allocable
portion of servicing  fees and other  miscellaneous  itemized  deductions of the
REMIC,  even  though  an  amount  equal to the  amount  of such  fees and  other
deductions will be included in the holder's gross income. Accordingly, the REMIC
certificates  may not be appropriate  investments for individuals,  estates,  or
trusts, or pass-through  entities beneficially owned by one or more individuals,
estates or trusts.  Any  prospective  investors  should  consult  with their tax
advisors prior to making an investment in these certificates.

     Tax and Restrictions on Transfers of REMIC Residual Certificates to Certain
Organizations

     If a REMIC residual certificate is transferred to a Disqualified
Organization, a tax would be imposed in an amount, determined under the REMIC
regulations, equal to: the product of

     (1) the present value,  discounted using the 'applicable  Federal rate' for
         obligations  whose term ends on the close of the last  quarter in which
         excess   inclusions   are  expected  to  accrue  with  respect  to  the
         certificate,  which rate is computed and published  monthly by the IRS,
         of the total  anticipated  excess  inclusions with respect to the REMIC
         residual certificate for periods after the transfer; and

     (2) the  highest   marginal   federal   income  tax  rate   applicable   to
         corporations.

     The  anticipated  excess  inclusions must be determined as of the date that
the REMIC residual  certificate is transferred  and must be based on events that
have  occurred up to the time of transfer,  the  prepayment  assumption  and any
required or permitted clean up calls or required liquidation provided for in the
REMIC's  organizational  documents.  This tax generally  would be imposed on the
transferor of the REMIC residual certificate,  except that where the transfer is
through  an agent for a  Disqualified  Organization,  the tax would  instead  be
imposed on that agent.  However,  a transferor of a REMIC  residual  certificate
would in no event  be  liable  for the tax with  respect  to a  transfer  if the
transferee furnishes to the transferor an affidavit that the transferee is not a
Disqualified  Organization  and, as of the time of the transfer,  the transferor
does not have actual knowledge that the affidavit is false.  Moreover, an entity
will not qualify as a REMIC unless there are reasonable arrangements designed to
ensure that:

      residual interests in the entity are not held by Disqualified
      Organizations; and

                                       77



<PAGE>



<PAGE>

      information necessary for the application of the tax described herein will
      be made available.

     Restrictions  on the  transfer  of REMIC  residual  certificates  and other
provisions  that are intended to meet this  requirement  will be included in the
pooling and servicing agreement, including provisions:

     (1) requiring any transferee of a REMIC residual  certificate to provide an
         affidavit  representing that it is not a Disqualified  Organization and
         is  not  acquiring  the  REMIC  residual  certificate  on  behalf  of a
         Disqualified  Organization,  undertaking  to  maintain  that status and
         agreeing to obtain a similar affidavit from any person to whom it shall
         transfer the REMIC residual certificate;

     (2) providing  that  any  transfer  of a REMIC  residual  certificate  to a
         Disqualified Organization shall be null and void; and

     (3) granting to the master servicer the right, without notice to the holder
         or any prior  holder,  to sell to a  purchaser  of its choice any REMIC
         residual   certificate  that  shall  become  owned  by  a  Disqualified
         Organization despite (1) and (2) above.

     In addition,  if a Pass-Through Entity includes in income excess inclusions
with respect to a REMIC residual certificate, and a Disqualified Organization is
the record  holder of an interest in that entity,  then a tax will be imposed on
the entity  equal to the product of (i) the amount of excess  inclusions  on the
REMIC  residual   certificate   that  are  allocable  to  the  interest  in  the
Pass-Through  Entity held by the Disqualified  Organization and (ii) the highest
marginal federal income tax rate imposed on corporations.  A Pass-Through Entity
will not be subject to this tax for any period,  however,  if each record holder
of an interest in the Pass-Through  Entity furnishes to that Pass-Through Entity
(i) the  holder's  social  security  number and a statement  under  penalties of
perjury that the social  security  number is that of the record holder or (ii) a
statement   under  penalties  of  perjury  that  the  record  holder  is  not  a
Disqualified Organization.  For taxable years beginning after December 31, 1997,
notwithstanding  the preceding two  sentences,  in the case of a REMIC  residual
certificate  held by an  'electing  large  partnership,'  all  interests in such
partnership  shall be treated  as held by  Disqualified  Organizations,  without
regard to whether  the  record  holders of the  partnership  furnish  statements
described in the preceding sentence, and the amount that is subject to tax under
the  second  preceding  sentence  is  excluded  from  the  gross  income  of the
partnership  allocated to the partners,  in lieu of allocating to the partners a
deduction for the tax paid by the partners.

     Sales of REMIC Certificates

     If  a  REMIC  Certificate  is  sold,  the  selling  certificateholder  will
recognize  gain or loss equal to the difference  between the amount  realized on
the sale and its adjusted basis in the REMIC Certificate.  The adjusted basis of
a REMIC regular certificate  generally will equal the cost of that REMIC regular
certificate  to that  certificateholder,  increased  by income  reported  by the
certificateholder  with  respect to that REMIC  regular  certificate,  including
original issue discount and market discount income,  and reduced,  but not below
zero,  by  distributions  on  the  REMIC  regular  certificate  received  by the
certificateholder  and by any amortized  premium.  The adjusted basis of a REMIC
residual  certificate  will be  determined  as described  under ' -- Taxation of
Owners  of  REMIC  Residual   Certificates  --  Basis  Rules,   Net  Losses  and
Distributions.'  Except as described  below,  any gain or loss generally will be
capital gain or loss.

     Gain from the sale of a REMIC regular  certificate  that might otherwise be
capital gain will be treated as ordinary  income to the extent the gain does not
exceed the excess,  if any, of (i) the amount that would have been includible in
the seller's  income with respect to the REMIC  regular  certificate  had income
accrued thereon at a rate equal to 110% of the 'applicable  federal rate,' which
is typically a rate based on an average of current yields on Treasury securities
having a maturity comparable to that of the certificate,  which rate is computed
and published  monthly by the IRS,  determined as of the date of purchase of the
REMIC  regular  certificate,  over (ii) the amount of ordinary  income  actually
includible  in  the  seller's  income  prior  to the  sale.  In  addition,  gain
recognized on the sale of a REMIC regular  certificate by a seller who purchased
the REMIC regular  certificate at a market  discount will be taxable as ordinary
income to the extent of any accrued and previously  unrecognized market discount
that accrued  during the period the  certificate  was held. See ' -- Taxation of
Owners of REMIC Regular Certificates -- Discount.'

     REMIC  certificates will be 'evidences of indebtedness'  within the meaning
of  Section  582(c)(1)  of the  Internal  Revenue  Code,  so  that  gain or loss
recognized from the sale of a REMIC certificate by a bank or thrift  institution
to which that section applies will be ordinary income or loss.

                                       78



<PAGE>



<PAGE>

     A portion  of any gain from the sale of a REMIC  regular  certificate  that
might  otherwise be capital gain may be treated as ordinary income to the extent
that the  certificate is held as part of a 'conversion  transaction'  within the
meaning of Section 1258 of the Internal  Revenue Code. A conversion  transaction
generally  is one in which  the  taxpayer  has taken  two or more  positions  in
certificates  or similar  property  that reduce or  eliminate  market  risk,  if
substantially  all of the taxpayer's return is attributable to the time value of
the taxpayer's net investment in the transaction. The amount of gain so realized
in a conversion transaction that is recharacterized as ordinary income generally
will not exceed the amount of interest that would have accrued on the taxpayer's
net investment at 120% of the appropriate  'applicable Federal rate,' which rate
is computed and  published  monthly by the IRS, at the time the taxpayer  enters
into the  conversion  transaction,  subject to  appropriate  reduction for prior
inclusion of interest and other ordinary income items from the transaction.

     Finally,  a taxpayer  may elect to have net capital  gain taxed at ordinary
income rates rather than capital gains rates in order to include any net capital
gain in total net  investment  income for the taxable year,  for purposes of the
limitation on the deduction of interest on indebtedness  incurred to purchase or
carry property held for investment to a taxpayer's net investment income.

     If the seller of a REMIC residual  certificate  reacquires the certificate,
any other  residual  interest in a REMIC or any  similar  interest in a 'taxable
mortgage  pool,' as defined in Section  7701(i) of the  Internal  Revenue  Code,
within six months of the date of the sale, the sale will be subject to the 'wash
sale' rules of Section 1091 of the Internal  Revenue  Code.  In that event,  any
loss realized by the REMIC residual  certificateholders  on the sale will not be
deductible,  but instead will be added to the REMIC residual  certificateholders
adjusted basis in the newly-acquired asset.

     Prohibited Transactions and Other Possible REMIC Taxes

     The Internal Revenue Code imposes a prohibited transactions tax, which is a
tax on  REMICs  equal  to  100%  of  the  net  income  derived  from  prohibited
transactions.   In  general,   subject  to  specified  exceptions  a  prohibited
transaction means the disposition of a mortgage loan, the receipt of income from
a source other than a mortgage loan or other permitted investments,  the receipt
of compensation for services, or gain from the disposition of an asset purchased
with the  payments  on the  mortgage  loans  for  temporary  investment  pending
distribution on the REMIC  certificates.  It is not  anticipated  that any REMIC
will  engage  in any  prohibited  transactions  in which it  would  recognize  a
material amount of net income. In addition,  some  contributions to a REMIC made
after the day on which the REMIC issues all of its interests could result in the
imposition of a contributions  tax, which is a tax on the REMIC equal to 100% of
the value of the contributed property. Each pooling and servicing agreement will
include provisions  designed to prevent the acceptance of any contributions that
would be subject to the tax.

     REMICs also are subject to federal income tax at the highest corporate rate
on 'net income from foreclosure  property,' determined by reference to the rules
applicable  to real estate  investment  trusts.  'Net  income  from  foreclosure
property'  generally means gain from the sale of a foreclosure  property that is
inventory  property  and gross  income  from  foreclosure  property  other  than
qualifying rents and other qualifying income for a real estate investment trust.
Unless  otherwise  disclosed  in the related  prospectus  supplement,  it is not
anticipated that any REMIC will recognize 'net income from foreclosure property'
subject to federal income tax.

     Unless otherwise disclosed in the related prospectus supplement,  it is not
anticipated  that any material  state or local  income or franchise  tax will be
imposed on any REMIC.

     Unless otherwise stated in the related  prospectus  supplement,  and to the
extent  permitted by then  applicable  laws,  any prohibited  transactions  tax,
contributions  tax,  tax on 'net income from  foreclosure  property' or state or
local income or franchise  tax that may be imposed on the REMIC will be borne by
the related master  servicer or the trustee in either case out of its own funds,
provided  that the  master  servicer  or the  trustee,  as the case may be,  has
sufficient  assets to do so, and  provided  further that the tax arises out of a
breach of the master  servicer's or the trustee's  obligations,  as the case may
be, under the related pooling and servicing agreement and relating to compliance
with applicable laws and  regulations.  Any tax not borne by the master servicer
or the trustee will be payable out of the related trust resulting in a reduction
in amounts payable to holders of the related REMIC certificates.

                                       79



<PAGE>



<PAGE>

     Termination

     A REMIC will terminate  immediately  after the distribution  date following
receipt by the REMIC of the final payment from the mortgage loans or upon a sale
of the REMIC's assets  following the adoption by the REMIC of a plan of complete
liquidation.  The  last  distribution  on a REMIC  regular  certificate  will be
treated as a payment in retirement of a debt instrument.  In the case of a REMIC
residual certificate, if the last distribution on the REMIC residual certificate
is less than the  certificateholder's  adjusted  basis in the  certificate,  the
certificateholder  should be treated as  realizing a loss equal to the amount of
the difference, and the loss may be treated as a capital loss.

     Reporting and Other Administrative Matters

     Solely  for  purposes  of the  administrative  provisions  of the  Internal
Revenue  Code,  the REMIC will be treated as a  partnership  and REMIC  residual
certificateholders  will be treated as partners.  Unless otherwise stated in the
related  prospectus  supplement,  the trustee will file REMIC federal income tax
returns on behalf of the related  REMIC and the entity  identified  as the REMIC
Administrator   in  the  related  pooling  and  servicing   agreement  or  REMIC
Administrator  will  prepare  the REMIC  federal  income tax returns and will be
designated  as and will act as the 'tax  matters  person'  for the  REMIC in all
respects, and may hold a nominal amount of REMIC residual certificates.

     As the tax matters person, the REMIC  Administrator will have the authority
to act on  behalf of the REMIC  and the  REMIC  residual  certificateholders  in
connection  with the  administrative  and  judicial  review of items of  income,
deduction,  gain or loss of the REMIC,  as well as the  REMIC's  classification.
REMIC  residual  certificateholders  will be  required to report the REMIC items
consistently  with their  treatment on the related REMIC's tax return and may in
some  circumstances  be  bound  by a  settlement  agreement  between  the  REMIC
Administrator, as tax matters person, and the IRS concerning any REMIC item.

     Adjustments  made to the  REMIC tax  return  may  require a REMIC  residual
certificateholders to make corresponding adjustments on its return, and an audit
of the REMIC's tax return,  or the  adjustments  resulting from an audit,  could
result  in an  audit  of  the  certificateholder's  return.  No  REMIC  will  be
registered  as a tax shelter  under  Section 6111 of the  Internal  Revenue Code
because it is not anticipated that any REMIC will have a net loss for any of the
first  five  taxable  years of its  existence.  Any  person  that  holds a REMIC
residual  certificate as a nominee for another person may be required to furnish
to the related REMIC,  in a manner to be provided in Treasury  regulations,  the
name and address of that person and other information.

     Reporting of interest income,  including any original issue discount,  with
respect to REMIC regular certificates is required annually,  and may be required
more  frequently  under  Treasury  regulations.  These  information  reports are
required to be sent to  individual  holders of REMIC  regular  Interests and the
IRS;  holders  of REMIC  regular  certificates  that are  corporations,  trusts,
securities  dealers  and other  non-individuals  will be provided  interest  and
original issue discount income  information and the information in the following
paragraph  upon request in accordance  with the  requirements  of the applicable
regulations.  The information must be provided by the later of 30 days after the
end of the quarter for which the information  was requested,  or two weeks after
the receipt of the  request.  The REMIC must also comply with rules  requiring a
REMIC regular certificate issued with original issue discount to disclose on its
face  information  including the amount of original issue discount and the issue
date, and requiring such  information to be reported to the IRS.  Reporting with
respect to the REMIC residual certificates, including income, excess inclusions,
investment  expenses and relevant  information  regarding  qualification  of the
REMIC's  assets  will  be made  as  required  under  the  Treasury  regulations,
typically on a quarterly basis.

     As  applicable,  the REMIC  regular  certificate  information  reports will
include a statement of the adjusted issue price of the REMIC regular certificate
at the beginning of each accrual period.  In addition,  the reports will include
information required by regulations with respect to computing the accrual of any
market discount.  Because exact computation of the accrual of market discount on
a constant yield method requires  information  relating to the holder's purchase
price that the REMIC  Administrator  will not have, the regulations only require
that information pertaining to the appropriate  proportionate method of accruing
market  discount  be  provided.  See ' --  Taxation  of Owners of REMIC  Regular
Certificates -- Market Discount.'

     The responsibility for complying with the foregoing reporting rules will be
borne by the REMIC Administrator. Certificateholders may request any information
with respect to the returns described in

                                       80

Section  1.6049-7(e)(2)  of the  Treasury  regulations.  Any  request  should be
directed to the REMIC  Administrator at Residential  Funding  Corporation,  8400
Normandale Lake Boulevard, Suite 600, Minneapolis, Minnesota 55437.

     Backup Withholding with Respect to REMIC Certificates

     Payments of interest and  principal,  as well as payments of proceeds  from
the sale of REMIC  certificates,  may be subject to the 'backup withholding tax'
under  Section 3406 of the Internal  Revenue Code at a rate of 31% if recipients
of payments fail to furnish to the payor certain  information,  including  their
taxpayer  identification  numbers,  or otherwise  fail to establish an exemption
from the tax.  Any  amounts  deducted  and  withheld  from a  distribution  to a
recipient  would be allowed as a credit against the  recipient's  federal income
tax. Furthermore, penalties may be imposed by the IRS on a recipient of payments
that is  required  to supply  information  but that does not do so in the proper
manner.

     Foreign Investors in REMIC Certificates

     A REMIC regular certificateholder that is not a United States person and is
not  subject  to  federal  income  tax as a result  of any  direct  or  indirect
connection  to the United States in addition to its ownership of a REMIC regular
certificate  will not be subject to United States  federal income or withholding
tax on a distribution on a REMIC regular  certificate,  provided that the holder
complies  to the extent  necessary  with  certain  identification  requirements,
including  delivery  of a  statement,  signed  by  the  certificateholder  under
penalties  of perjury,  certifying  that the  certificateholder  is not a United
States person and providing the name and address of the  certificateholder.  For
these  purposes,  United States person means a citizen or resident of the United
States,  a corporation,  partnership or other entity created or organized in, or
under the laws of, the United  States,  any state  thereof  or the  District  of
Columbia,  except,  in the case of a  partnership,  to the  extent  provided  in
regulations,  or an estate  whose  income is  subject to United  States  federal
income tax  regardless  of its source,  or a trust if a court  within the United
States is able to exercise primary  supervision over the  administration  of the
trust and one or more United  States  persons have the  authority to control all
substantial  decisions of the trust. To the extent  prescribed in regulations by
the Secretary of the Treasury,  which  regulations  have not yet been issued,  a
trust which was in existence on August 20, 1996,  other than a trust  treated as
owned by the grantor  under  subpart E of part I of subchapter J of chapter 1 of
the Internal  Revenue  Code,  and which was treated as a United States person on
August 19, 1996,  may elect to continue to be treated as a United  States person
notwithstanding  the previous  sentence.  It is possible that the IRS may assert
that the  foregoing  tax  exemption  should  not apply  with  respect to a REMIC
regular  certificate  held  by a  REMIC  residual  certificateholder  that  owns
directly  or  indirectly  a 10%  or  greater  interest  in  the  REMIC  residual
certificates.  If the holder does not qualify for  exemption,  distributions  of
interest,  including  distributions of accrued  original issue discount,  to the
holder  may be  subject to a tax rate of 30%,  subject  to  reduction  under any
applicable tax treaty.

     In addition,  the foregoing  rules will not apply to exempt a United States
shareholder  of a controlled  foreign  corporation  from  taxation on the United
States  shareholder's  allocable  portion of the interest income received by the
controlled foreign corporation.

     Further,  it appears that a REMIC regular certificate would not be included
in the estate of a  non-resident  alien  individual  and would not be subject to
United States estate taxes.  However,  certificateholders  who are  non-resident
alien individuals should consult their tax advisors concerning this question.

     Unless otherwise stated in the related prospectus supplement,  transfers of
REMIC residual certificates to investors that are not United States persons will
be prohibited under the related pooling and servicing agreement.

     New Withholding Regulations

     The Treasury  Department has issued New  Regulations.  The New  Regulations
attempt to unify certification  requirements and modify reliance standards.  The
New Regulations will generally be effective for payments made after December 31,
2000,  subject to certain transition rules.  Prospective  investors are urged to
consult their tax advisors regarding the New Regulations.

                        STATE AND OTHER TAX CONSEQUENCES

     In addition to the federal income tax  consequences  described in 'Material
Federal Income Tax Consequences,'  potential investors should consider the state
and local tax consequences of the acquisition, ownership, and disposition of the
certificates offered hereunder.  State tax law may differ substantially from the
corresponding  federal  tax law,  and the  discussion  above does not purport to
describe  any  aspect  of the  tax  laws of any  state  or  other  jurisdiction.
Therefore,  prospective investors should consult their tax advisors with respect
to the various tax  consequences  of  investments  in the  certificates  offered
hereby.

                              ERISA CONSIDERATIONS

     Sections  404 and 406 of the  Employee  Retirement  Income  Security Act of
1974, or ERISA,  impose  fiduciary and prohibited  transaction  restrictions  on
employee  pension  and  welfare  benefit  plans  subject  to ERISA  and on other
retirement plans and arrangements,  including individual retirement accounts and
annuities,  Keogh plans, bank collective  investment funds and insurance company
general and separate  accounts in which those ERISA plans are invested.  Section
4975 of the  Internal  Revenue  Code  imposes  essentially  the same  prohibited
transaction  restrictions on tax-qualified retirement plans described in Section
401(a)  of the  Internal  Revenue  Code and on  individual  retirement  accounts
described in Section 408 of the Internal Revenue Code. Such plans, together with
plans subject to ERISA, are referred to as ERISA plans.

     Some employee benefit plans,  including  governmental  plans, as defined in
Section 3(32) of ERISA,  and if no election has been under Section 410(d) of the
Internal  Revenue Code,  church plans, as defined in Section 3(33) of ERISA, are
not subject to the ERISA requirements discussed in this prospectus. Accordingly,
assets of these  plans may be  invested in  certificates  without  regard to the
ERISA  considerations  described below,  subject to the provisions of applicable
federal  and state law.  Any plan that is a  tax-qualified  plan and exempt from
taxation under Sections 401(a) and 501(a) of the Internal Revenue Code, however,
is subject to the  prohibited  transaction  rules in Section 503 of the Internal
Revenue Code.

     In addition to imposing general fiduciary requirements,  including those of
investment prudence and diversification and the requirement that an ERISA plan's
investment  be made in accordance  with the documents  governing the ERISA plan,
Section 406 of ERISA and Section  4975 of the Internal  Revenue Code  prohibit a
broad range of  transactions  involving 'plan assets' of ERISA plans and Parties
in  Interest,  unless a statutory  or  administrative  exemption  is  available.
Certain Parties in Interest that participate in a prohibited  transaction may be
subject to a penalty, or an excise tax, imposed under Section 502(i) of ERISA or
Section 4975 of the Internal Revenue Code,  unless a statutory or administrative
exemption is available with respect to any transaction of this sort.

ERISA PLAN ASSET REGULATIONS

     An investment of ERISA plan assets in certificates may cause the underlying
mortgage loans,  mortgage  securities or any other assets included in a trust to
be deemed 'plan assets' of the ERISA plan. The U.S. Department of Labor, or DOL,
has promulgated  regulations at 29 C.F.R. Section 2510.3-101 or, DOL Regulations
concerning  whether or not an ERISA plan's  assets would be deemed to include an
interest in the underlying assets of an entity,  including a trust, for purposes
of applying the general  fiduciary  responsibility  provisions  of ERISA and the
prohibited  transaction  provisions  of ERISA and Section  4975 of the  Internal
Revenue Code, when an ERISA plan's assets acquires an 'equity interest,' such as
a certificate, in that entity.

     Because of the factual nature of some of the rules in the DOL  Regulations,
ERISA plan  assets  either may be deemed to include an interest in the assets of
an entity, including a trust, or may be deemed merely to include an ERISA plan's
interest  in  the  instrument  evidencing  such  equity  interest,   such  as  a
certificate.  Therefore, neither ERISA plans nor such entities should acquire or
hold  certificates in reliance upon the  availability of any exception under the
DOL Regulations. For purposes of this section, the term ERISA plan or 'assets of
an ERISA plan' has the meaning  specified in the DOL Regulations and includes an
undivided  interest in the underlying  assets of some entities in which an ERISA
plan invests.

     The prohibited  transaction  provisions of Section 406 of ERISA and Section
4975 of the Internal  Revenue Code may apply to a trust and cause the depositor,
the master servicer, any subservicer,  the trustee, the obligor under any credit
enhancement  mechanism or certain  affiliates of those entities to be considered
or become  Parties in Interest with respect to an investing  ERISA plan or of an
ERISA plan holding an interest in such an

                                       82

<PAGE>

entity. If so, the acquisition or holding of certificates by or on behalf of the
investing  ERISA plan assets  could also give rise to a  prohibited  transaction
under ERISA  and/or  Section  4975 of the  Internal  Revenue  Code,  unless some
statutory or administrative exemption is available.  Certificates acquired by an
ERISA plan  would be assets of that ERISA  plan.  Under the DOL  Regulations,  a
trust,  including the mortgage  loans,  mortgage  securities or any other assets
held in the  trust,  may also be deemed to be  assets  of each  ERISA  plan that
acquires  certificates.  Special  caution should be exercised  before ERISA plan
assets are used to acquire a certificate in those circumstances,  especially if,
with respect to the ERISA plan assets, the depositor,  the master servicer,  any
subservicer,  the trustee, the obligor under any credit enhancement mechanism or
an affiliate  thereof either (i) has investment  discretion  with respect to the
investment of the ERISA plan assets;  or (ii) has authority or responsibility to
give, or regularly  gives,  investment  advice with respect to ERISA plan assets
for a fee under an  agreement or  understanding  that any advice will serve as a
primary basis for investment decisions with respect to the ERISA plan assets.

     Any person  who has  discretionary  authority  or  control  respecting  the
management  or  disposition  of ERISA plan  assets,  and any person who provides
investment advice with respect to the ERISA plan assets for a fee, in the manner
described  above,  is a fiduciary of the  investing  ERISA plan. If the mortgage
loans,  mortgage  securities  or any  other  assets  held  in a  trust  were  to
constitute  ERISA  plan  assets,   then  any  party  exercising   management  or
discretionary  control  with respect to those ERISA plan assets may be deemed to
be an  ERISA  plan  assets  'fiduciary,'  and  thus  subject  to  the  fiduciary
requirements  of ERISA and the  prohibited  transaction  provisions of ERISA and
Section 4975 of the Internal  Revenue Code with respect to any  investing  ERISA
plan.  In addition,  if the mortgage  loans,  mortgage  securities  or any other
assets  held  in a  trust  were  to  constitute  ERISA  plan  assets,  then  the
acquisition  or holding of  certificates  by, on behalf of an ERISA plan or with
ERISA plan assets,  as well as the  operation of such trust,  may  constitute or
result in a prohibited transaction under ERISA and the Internal Revenue Code.

PROHIBITED TRANSACTION EXEMPTION

     The  DOL  has  issued  an  individual  exemption,   Prohibited  Transaction
exemption,  or PTE 94-29,  59 Fed. Reg. 14674 (March 29, 1994) as amended by PTE
97-34,  62 Fed. Reg. 39021 (July 21, 1997), to Residential  Funding  Corporation
and certain of its affiliates,  which generally  exempts from the application of
the prohibited  transaction  provisions of Section 406 of ERISA,  and the excise
taxes imposed on the prohibited transactions pursuant to Section 4975(a) and (b)
of the Internal Revenue Code, certain  transactions,  among others,  relating to
the  servicing and operation of mortgage  pools of certain  secured  obligations
including mortgage loans,  which are held in a trust and the purchase,  sale and
holding of  pass-through  certificates  issued by that trust as to which (i) the
depositor  or any of its  affiliates  is the  sponsor  if any  entity  which has
received from the DOL an individual  prohibited  transaction  exemption which is
similar to the  exemption is the sole  underwriter,  or manager or co-manager of
the underwriting syndicate or a seller or placement agent, or (ii) the depositor
or an affiliate is the underwriter or placement agent,  provided that conditions
in the  exemption  are  satisfied.  For  purposes  of  this  section,  the  term
Underwriter  shall include (a) the depositor and certain of its affiliates,  (b)
any  person  directly  or  indirectly,   through  one  or  more  intermediaries,
controlling,  controlled  by or under  common  control  with the  depositor  and
certain of its  affiliates,  (c) any  member of the  underwriting  syndicate  or
selling  group  of  which  a  person  described  in (a) or (b) is a  manager  or
co-manager with respect to a class of certificates,  or (d) any entity which has
received an exemption from the DOL relating to certificates  which is similar to
the exemption.

     The exemption sets forth six general conditions which must be satisfied for
a transaction  involving the purchase,  sale and holding of  certificates  to be
eligible for exemptive relief thereunder. First, the acquisition of certificates
by an ERISA plan or with ERISA plan assets must be on terms that are at least as
favorable to the ERISA plan as they would be in an arm's-length transaction with
an  unrelated  party.   Second,  the  exemption  only  applies  to  certificates
evidencing  rights and  interests  that are not  subordinated  to the rights and
interests  evidenced by the other  certificates  of the same trust.  Third,  the
certificates  at the time of  acquisition  by an ERISA  plan or with  ERISA plan
assets must be rated in one of the three highest  generic  rating  categories by
Standard & Poor's, a division of McGraw Hill Companies,  Inc., Moody's Investors
Service,  Inc.,  Duff & Phelps  Credit  Rating Co. or Fitch IBCA,  Inc.,  or the
exemption  rating  agencies.  Fourth,  the trustee cannot be an affiliate of any
other member of the  restricted  group which  consists of any  underwriter,  the
depositor,  the master servicer, any subservicer,  the trustee and any mortgagor
with respect to assets of a trust constituting more than

                                       83



<PAGE>



<PAGE>

5% of the aggregate  unamortized  principal balance of the assets in the related
trust as of the date of initial issuance of the certificates.  Fifth, the sum of
all payments made to and retained by the  Underwriters  must  represent not more
than reasonable  compensation for underwriting the certificates;  the sum of all
payments made to and retained by the depositor pursuant to the assignment of the
assets to the related  trust must  represent not more than the fair market value
of those  obligations;  and the sum of all payments  made to and retained by the
master  servicer and any  subservicer  must  represent not more than  reasonable
compensation for that person's  services under the related pooling and servicing
agreement and reimbursement of that person's  reasonable  expenses in connection
therewith.  Sixth,  the exemption  states that the investing ERISA plan or ERISA
plan assets investor must be an accredited investor as defined in Rule 501(a)(1)
of Regulation D of the Securities and Exchange  Commission  under the Securities
Act. In  addition,  except as  otherwise  specified  in the  related  prospectus
supplement,  the exemptive relief afforded by the exemption may not apply to any
certificates where the related trust contains a swap.

     The   exemption   also   requires   that  each  trust  meet  the  following
requirements:

      the trust must consist solely of assets of the type that have been
      included in other investment pools

      certificates  evidencing  interests in those other  investment  pools must
      have  been  rated in one of the  three  highest  categories  of one of the
      exemption  rating  agencies for at least one year prior to the acquisition
      of  certificates  by or on  behalf  of an ERISA  plan or with  ERISA  plan
      assets; and

      certificates  in the other  investment  pools must have been  purchased by
      investors  other  than  ERISA  plans  for at least  one year  prior to any
      acquisition of certificates by or on behalf of an ERISA plan or with ERISA
      plan assets.

     A  fiduciary  of or other  investor  of  ERISA  plan  assets  contemplating
purchasing  a  certificate  must  make its own  determination  that the  general
conditions described above will be satisfied with respect to that certificate.

     If the general conditions of the exemption are satisfied, the exemption may
provide an exemption from the restrictions imposed by Sections 406(a) and 407(a)
of ERISA,  and the excise  taxes  imposed  by  Sections  4975(a)  and (b) of the
Internal  Revenue  Code by reason of Sections  4975(c)(1)(A)  through (D) of the
Internal Revenue Code, in connection with the direct or indirect sale, exchange,
transfer,  holding or the direct or indirect  acquisition  or disposition in the
secondary  market of  certificates  by or with ERISA plan  assets.  However,  no
exemption  is  provided  from the  restrictions  of  Sections  406(a)(1)(E)  and
406(a)(2) of ERISA for the  acquisition  or holding of a certificate  by or with
ERISA  plan  assets of an  excluded  plan by any  person  who has  discretionary
authority or renders  investment advice with respect to ERISA plan assets of the
excluded  plan. For purposes of the  certificates,  an excluded ERISA plan is an
ERISA plan sponsored by any member of the restricted group.

     If specific  conditions of the exemption are also satisfied,  the exemption
may provide an exemption from the restrictions imposed by Sections 406(b)(1) and
(b)(2) of ERISA, and the excise taxes imposed by Sections 4975(a) and (b) of the
Internal Revenue Code by reason of Section 4975(c)(1)(E) of the Internal Revenue
Code, in connection with the following:

     (1) the direct or indirect sale,  exchange or transfer of  certificates  in
         the  initial  issuance of  certificates  between  the  depositor  or an
         underwriter  and an ERISA plan when the  person  who has  discretionary
         authority or renders  investment  advice with respect to the investment
         of the relevant ERISA plan assets in the certificates is:

         (a) a mortgagor  with respect to 5% or less of the fair market value of
             the assets of a trust; or

         (b) an affiliate of such a person.

     (2) the direct or indirect  acquisition  or  disposition  in the  secondary
         market of certificates by an ERISA plan or with ERISA plan assets; and

     (3) the holding of certificates by an ERISA plan or with ERISA plan assets.

     Additionally,  if specific  conditions of the exemption are satisfied,  the
exemption  may provide an exemption  from the  restrictions  imposed by Sections
406(a),  406(b) and 407(a) of ERISA,  and the excise  taxes  imposed by Sections
4975(a) and (b) of the Internal Revenue Code by reason of Section 4975(c) of the
Internal  Revenue  Code,  for  transactions  in connection  with the  servicing,
management and operation of the mortgage pools.  The depositor  expects that the
specific conditions of the exemption required for this purpose will be satisfied
with

                                       84



<PAGE>



<PAGE>

respect to the  certificates  so that the  exemption  would provide an exemption
from the  restrictions  imposed by  Sections  406(a)  and (b) of ERISA,  and the
excise taxes imposed by Sections 4975(a) and (b) of the Internal Revenue Code by
reason of Section  4975(c) of the Internal  Revenue Code,  for  transactions  in
connection  with the servicing,  management and operation of the mortgage pools,
provided that the general conditions of the exemption are satisfied.

     The exemption also may provide an exemption from the  restrictions  imposed
by Sections 406(a) and 407(a) of ERISA, and the excise taxes imposed by Sections
4975(a) and (b) of the Internal Revenue Code by reason of Sections 4975(c)(1)(A)
through (D) of the Internal  Revenue Code, if those  restrictions  are deemed to
otherwise apply merely because a person is deemed to be a Party in Interest with
respect to an investing  ERISA plan,  or an ERISA plan holding  interests in the
investing entity holding ERISA plan assets,  by virtue of providing  services to
the  ERISA  plan or the ERISA  plan  assets,  or by  virtue of having  specified
relationships to such a person, solely as a result of the ERISA plan's ownership
of certificates.

     Before  purchasing a  certificate,  a fiduciary or other  investor of ERISA
plan  assets  should  itself  confirm  that  (a)  the  certificates   constitute
'certificates'  for purposes of the  exemption  and (b) the specific and general
conditions  described  in  the  exemption  and  the  other  requirements  in the
exemption would be satisfied.  In addition to making its own determination as to
the  availability  of  the  exemptive  relief  provided  in the  exemption,  the
fiduciary  or other  ERISA plan  assets  investor  should  consider  its general
fiduciary  obligations  under  ERISA in  determining  whether  to  purchase  any
certificates with ERISA plan assets.

     Any fiduciary or other ERISA plan assets investor that proposes to purchase
certificates on behalf of an ERISA plan or with ERISA plan assets should consult
with its counsel with respect to the  potential  applicability  of ERISA and the
Internal  Revenue Code to that investment and the  availability of the exemption
or any other DOL prohibited  transaction exemption in connection  therewith.  In
particular,   in  connection  with  a  contemplated   purchase  of  certificates
representing  a  beneficial  ownership  interest  in  a  pool  of  single-family
residential  first  mortgage  loans,  the  fiduciary  or other ERISA plan assets
investor  should  consider  the  availability  of the  exemption  or  Prohibited
Transaction  Class exemption,  or PTCE 83-1, or PTCE 83-1 for some  transactions
involving mortgage pool investment trusts.  However,  PTCE 83-1 does not provide
exemptive  relief with respect to  certificates  evidencing  interests in trusts
which include Cooperative Loans or some types of mortgage  securities,  or which
contain a swap. In addition,  the fiduciary or other ERISA plan assets  investor
should consider the availability of other class  exemptions  granted by the DOL,
which provide  relief from certain of the prohibited  transaction  provisions of
ERISA and the related  excise tax  provisions  of Section  4975 of the  Internal
Revenue Code, including Sections I and III of PTCE 95-60, regarding transactions
by insurance company general  accounts.  The related  prospectus  supplement may
contain additional information regarding the application of the exemption,  PTCE
83-1, PTCE 95-60 or other DOL class  exemption with respect to the  certificates
offered  thereby.  There can be no assurance that any of these  exemptions  will
apply with  respect to any  particular  ERISA  plan's or other ERISA plan assets
investor's  investment in the  certificates or, even if an exemption were deemed
to apply, that any exemption would apply to all prohibited transactions that may
occur in connection with this form of investment.

INSURANCE COMPANY GENERAL ACCOUNTS

     In addition to any exemptive  relief that may be available under PTCE 95-60
for the purchase and holding of the certificates by an insurance company general
account,  the Small  Business  Job  Protection  Act of 1996 added a new  Section
401(c) to ERISA,  which provides  exemptive relief from the provisions of Part 4
of Title I of ERISA and Section 4975 of the Internal Revenue Code, including the
prohibited  transaction  restrictions  imposed by ERISA and the  related  excise
taxes  imposed by Section 4975 of the Internal  Revenue Code,  for  transactions
involving an insurance company general account.

     The  401(c)  Regulations  are  to  provide  guidance  for  the  purpose  of
determining, in cases where insurance policies or annuity contracts supported by
an insurer's  general  account are issued to or for the benefit of an ERISA plan
on or before December 31, 1998,  which general account assets  constitute  ERISA
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 or Section  4975 of the
Internal  Revenue  Code on the basis of a claim that the assets of an  insurance
company general account  constitute  ERISA 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

                                       85



<PAGE>



<PAGE>

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 or annuity contracts issued to an ERISA
plan after December 31, 1998 or issued to ERISA plans on or before  December 31,
1998 for which the insurance company does not comply with the 401(c) Regulations
may be treated as ERISA plan assets.  In addition,  because  Section 401(c) does
not relate to insurance company separate  accounts,  separate account assets are
still  treated as ERISA plan  assets of any ERISA  plan  invested  in a separate
account.  Insurance  companies  contemplating  the investment of general account
assets in the certificates  should consult with their legal counsel with respect
to the  applicability  of Sections I and III of PTCE 95-60 and Section 401(c) of
ERISA,  including  the  general  account's  ability  to  continue  to  hold  the
certificates  after  the  date  which is 18  months  after  the date the  401(c)
Regulations become final.

REPRESENTATIONS FROM INVESTING PLANS

     The  exemptive  relief  afforded  by the  exemption  will not  apply to the
purchase,  sale or holding  of any class of  subordinate  certificates  or REMIC
residual certificates.  To the extent certificates are subordinate  certificates
or the related  trust  contains a swap,  except as  otherwise  specified  in the
related prospectus supplement, transfers of those certificates to an ERISA plan,
to a trustee or other person acting on behalf of any ERISA plan, or to any other
person using ERISA plan assets to effect the acquisition  will not be registered
by the trustee unless the transferee provides the depositor, the trustee and the
master servicer with an opinion of counsel  satisfactory  to the depositor,  the
trustee and the master servicer, which opinion will not be at the expense of the
depositor,  the  trustee  or the  master  servicer,  that  the  purchase  of the
certificates  by or on behalf of the ERISA  plan or with  ERISA  plan  assets is
permissible  under  applicable  law,  will  not  constitute  or  result  in  any
non-exempt  prohibited  transaction  under ERISA or Section 4975 of the Internal
Revenue  Code and will not  subject  the  depositor,  the  trustee or the master
servicer to any  obligation  in addition to those  undertaken in the pooling and
servicing agreement.

     In lieu of an opinion of  counsel,  except as  otherwise  specified  in the
related  prospectus  supplement,  the transferee may provide a certification  of
facts substantially to the effect that the purchase of the certificates by or on
behalf  of the  ERISA  plan or with  ERISA  plan  assets  is  permissible  under
applicable  law,  will not  constitute  or  result  in a  non-exempt  prohibited
transaction  under ERISA or Section 4975 of the Internal  Revenue Code, will not
subject the depositor,  the trustee or the master  servicer to any obligation in
addition to those  undertaken  in the pooling and servicing  agreement,  and the
following  conditions  are met:  (a) the  source of funds used to  purchase  the
certificates is an 'insurance  company general account' (as that term is defined
in PTCE 95-60),  and (b) the conditions in Sections I and III of PTCE 95-60 have
been satisfied as of the date of the acquisition of the certificates.

TAX-EXEMPT INVESTORS

     A  Tax-Exempt  Investor  nonetheless  will be  subject  to  federal  income
taxation  to  the  extent  that  its  income  is  'unrelated   business  taxable
income,'or, UBTI within the meaning of Section 512 of the Internal Revenue Code.
All 'excess  inclusions' of a REMIC  allocated to a REMIC  residual  certificate
held by a Tax-Exempt  Investor will be considered  UBTI and thus will be subject
to federal income tax. See 'Material Federal Income Tax Consequences -- Taxation
of Owners of REMIC Residual Certificates -- Excess Inclusions.'

CONSULTATION WITH COUNSEL

     There can be no assurance  that the  exemption  or any other DOL  exemption
will  apply  with  respect  to any  particular  ERISA  plan  that  acquires  the
certificates or, even if all of the conditions specified therein were satisfied,
that  the  exemption  would  apply  to  all  transactions   involving  a  trust.
Prospective  ERISA  plan  investors  should  consult  with their  legal  counsel
concerning  the impact of ERISA and the Internal  Revenue Code and the potential
consequences  to their specific  circumstances  prior to making an investment in
the certificates.

     Any  fiduciary  or other  investor of ERISA plan  assets  that  proposes to
acquire  or hold  certificates  on behalf of an ERISA  plan or with  ERISA  plan
assets   should   consult  with  its  counsel  with  respect  to  the  potential
applicability  of the  fiduciary  responsibility  provisions  of  ERISA  and the
prohibited  transaction  provisions  of ERISA and Section  4975 of the  Internal
Revenue Code to the proposed investment and the exemption and the

                                       86

availability  of exemptive  relief  under PTCE 83-1,  Sections I and III of PTCE
95-60 or any other DOL class exemption.

                            LEGAL INVESTMENT MATTERS

     Each class of  certificates  offered  hereby and by the related  prospectus
supplement  will be  rated at the date of  issuance  in one of the four  highest
rating  categories by at least one rating agency. If so specified in the related
prospectus supplement, classes that are, and continue to be, rated in one of the
two highest rating categories by at least one nationally recognized  statistical
rating  organization will constitute  'mortgage related securities' for purposes
of the Secondary Mortgage Market Enhancement Act of 1984, as amended,  or SMMEA,
and, as such,  will be legal  investments  for  persons,  trusts,  corporations,
partnerships,  associations,  business trusts and business  entities,  including
depository  institutions,  life insurance  companies and pension funds,  created
under or  existing  under the laws of the  United  States or of any State  whose
authorized  investments are subject to state regulation to the same extent that,
under  applicable law,  obligations  issued by or guaranteed as to principal and
interest  by  the  United  States  or  any  agency  or  instrumentality  thereof
constitute legal investments for those entities. Under SMMEA, if a State enacted
legislation  on or prior to  October  3, 1991  specifically  limiting  the legal
investment  authority of any of these entities with respect to 'mortgage related
securities,'  these  securities will constitute  legal  investments for entities
subject to the legislation only to the extent provided  therein.  Certain States
enacted  legislation which overrides the preemption  provisions of SMMEA.  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
'mortgage  related  securities,' or require the sale or other disposition of the
securities,  so long as the  contractual  commitment  was made or the securities
acquired prior to the enactment of the legislation.

     SMMEA also amended the legal  investment  authority of  federally-chartered
depository  institutions as follows:  federal savings and loan  associations and
federal  savings  banks may invest in,  sell or  otherwise  deal with  'mortgage
related  securities'  without  limitation  as to the  percentage of their assets
represented thereby,  federal credit unions may invest in these securities,  and
national  banks may  purchase  these  securities  for their own account  without
regard to the  limitations  generally  applicable to investment  securities  set
forth in 12 U.S.C. SS24 (Seventh),  subject in each case to any regulations that
the applicable federal regulatory authority may prescribe.

     The 1998 Policy  Statement was adopted by the Federal  Reserve  Board,  the
Office of the  Comptroller of the Currency,  the FDIC, the National Credit Union
Administration,  or NCUA and the OTS with an effective date of May 26, 1998. The
1998 Policy Statement rescinded a 1992 policy statement that had required, prior
to purchase, a depository institution to determine whether a mortgage derivative
product that it was  considering  acquiring was high-risk,  and, if so, required
that the proposed  acquisition would reduce the  institution's  overall interest
rate risk.  The 1998 Policy  Statement  eliminates  constraints  on investing in
certain  'high-risk'   mortgage  derivative  products  and  substitutes  broader
guidelines for evaluating and monitoring investment risk.

     The OTS has issued Thrift  Bulletin 13a,  entitled  'Management of Interest
Rate Risk, Investment Securities,  and Derivatives Activities,' or TB 13a, which
is effective as of December 1, 1998 and applies to thrift institutions regulated
by the  OTS.  One of  the  primary  purposes  of TB  13a  is to  require  thrift
institutions,  prior  to  taking  any  investment  position  to  conduct  (i)  a
pre-purchase  portfolio  sensitivity analysis for any 'significant  transaction'
involving  securities or financial  derivatives,  and (ii) a pre-purchase  price
sensitivity analysis of any 'complex security' or financial derivative.  For the
purposes  of TB 13a,  'complex  security'  includes,  among  other  things,  any
collateralized  mortgage  obligation  or REMIC  security,  other than any 'plain
vanilla' mortgage  pass-through security (that is, securities that are part of a
single class of securities in the related pool that are  non-callable and do not
have any special features).  One or more classes of certificates  offered hereby
and by the related prospectus  supplement may be viewed as 'complex securities.'
The OTS  recommends  that  while a thrift  institution  should  conduct  its own
in-house  pre-acquisition  analysis,  it may rely on an analysis conducted by an
independent  third-party as long as management  understands the analysis and its
key assumptions.  Further, TB 13a recommends that the use of 'complex securities
with high price  sensitivity'  be limited to  transactions  and strategies  that
lower a thrift  institution's  portfolio  interest  rate risk. TB 13a warns that
investment  in  complex  securities  by  thrift  institutions  that do not  have
adequate risk  measurement,  monitoring and control systems may be viewed by OTS
examiners as an unsafe and unsound practice.

     Prospective  investors in the  certificates,  including in  particular  the
classes of certificates that do not constitute 'mortgage related securities' for
purposes of SMMEA,  should  consider  the  matters  discussed  in the  following
paragraph.

     There may be other  restrictions on the ability of some investors either to
purchase some classes of  certificates  or to purchase any class of certificates
representing  more than a specified  percentage of the  investors'  assets.  The
depositor will make no representations as to the proper  characterization of any
class of  certificates  for legal  investment  or other  purposes,  or as to the
ability of  particular  investors  to purchase any class of  certificates  under
applicable  legal investment  restrictions.  These  uncertainties  may adversely
affect the liquidity of any class of  certificates.  Accordingly,  all investors
whose   investment   activities  are  subject  to  legal   investment  laws  and
regulations, regulatory capital requirements or review by regulatory authorities
should consult with their own legal advisors in determining  whether and to what
extent the certificates of any class constitute legal investments or are subject
to investment, capital or other restrictions,  and, if applicable, whether SMMEA
has been overridden in any jurisdiction relevant to the investor.

                                USE OF PROCEEDS

     Substantially  all of the net  proceeds  to be  received  from  the sale of
certificates  will be applied by the depositor to finance the purchase of, or to
repay  short-term  loans incurred to finance the purchase of, the mortgage loans
underlying  the  certificates  or  will be used  by the  depositor  for  general
corporate purposes.  The depositor expects that it will make additional sales of
securities  similar to the  certificates  from time to time,  but the timing and
amount of any  additional  offerings will be dependent upon a number of factors,
including the volume of mortgage loans  purchased by the  depositor,  prevailing
interest rates, availability of funds and general market conditions.

                            METHODS OF DISTRIBUTION

     The certificates  offered hereby and by the related prospectus  supplements
will be offered in series  through one or more of the methods  described  below.
The prospectus  supplement  prepared for each series will describe the method of
offering  being  utilized for that series and will state the net proceeds to the
depositor from that sale.

     The  depositor  intends  that  certificates  will be  offered  through  the
following  methods from time to time and that offerings may be made concurrently
through  more than one of these  methods  or that an  offering  of a  particular
series of  certificates  may be made through a combination of two or more of the
following methods:

      by negotiated firm commitment or best efforts underwriting and public
      re-offering by underwriters

      by placements by the depositor with institutional investors through
      dealers; and

      by direct placements by the depositor with institutional investors.

     In addition, if specified in the related prospectus supplement, a series of
certificates  may be offered  in whole or in part to the  seller of the  related
mortgage loans that would comprise the mortgage pool securing the certificates.

     If  underwriters  are  used in a sale of any  certificates,  other  than in
connection with an underwriting on a best efforts basis, the  certificates  will
be  acquired  by the  underwriters  for their own account and may be resold from
time to time in one or more transactions,  including negotiated transactions, at
fixed public  offering  prices or at varying prices to be determined at the time
of sale  or at the  time  of  commitment  therefor.  These  underwriters  may be
broker-dealers  affiliated with the depositor whose identities and relationships
to the depositor will be as described in the related prospectus supplement.  The
managing  underwriter  or  underwriters  with respect to the offer and sale of a
particular  series  of  certificates  will  be set  forth  on the  cover  of the
prospectus   supplement   relating  to  that  series  and  the  members  of  the
underwriting  syndicate,  if  any,  will  be  named  in the  related  prospectus
supplement.

     In connection with the sale of the  certificates,  underwriters may receive
compensation  from the depositor or from  purchasers of the  certificates in the
form  of  discounts,  concessions  or  commissions.   Underwriters  and  dealers
participating  in the  distribution  of the  certificates  may be  deemed  to be
underwriters  in  connection  with  the  certificates,   and  any  discounts  or
commissions received by them from the depositor and any profit on the

                                       88



<PAGE>



<PAGE>

resale of certificates  by them may be deemed to be  underwriting  discounts and
commissions under the Securities Act.

     It is anticipated that the underwriting agreement pertaining to the sale of
any series of certificates will provide that the obligations of the underwriters
will be subject to certain conditions  precedent,  that the underwriters will be
obligated to purchase all of the  certificates if any are purchased,  other than
in connection with an underwriting on a best efforts basis, and that, in limited
circumstances,  the depositor  will indemnify the several  underwriters  and the
underwriters  will indemnify the depositor  against  certain civil  liabilities,
including  liabilities  under the Securities Act, or will contribute to payments
required to be made in respect thereof.

     The prospectus  supplement with respect to any series offered by placements
through  dealers will contain  information  regarding the nature of the offering
and any  agreements to be entered into between the  depositor and  purchasers of
certificates of that series.

     The depositor anticipates that the certificates offered hereby will be sold
primarily  to  institutional   investors  or   sophisticated   non-institutional
investors. Purchasers of certificates,  including dealers, may, depending on the
facts and circumstances of the purchases,  be deemed to be 'underwriters' within
the meaning of the Securities Act, in connection with reoffers and sales by them
of  certificates.  Holders of  certificates  should  consult  with  their  legal
advisors in this regard prior to any reoffer or sale.

                                 LEGAL MATTERS

     Certain legal matters,  including certain federal income tax matters,  will
be passed upon for the Company by Thacher  Proffitt & Wood,  New York, New York,
Orrick, Herrington & Sutcliffe LLP, New York, New York or by Stroock & Stroock &
Lavan LLP, as specified in the prospectus supplement.

                             FINANCIAL INFORMATION

     The depositor has determined that its financial statements are not material
to the offering made hereby. The certificates do not represent an interest in or
an obligation of the depositor. The depositor's only obligations with respect to
a series of  certificates  will be to  repurchase  the  mortgage  loans upon any
breach of limited  representations  and warranties made by the depositor,  or as
otherwise provided in the applicable prospectus supplement.

                             ADDITIONAL INFORMATION

     The depositor has filed the registration  statement with the Securities and
Exchange  Commission.  The depositor is also subject to some of the  information
requirements  of the  Securities  Exchange Act of 1934, as amended,  or Exchange
Act, and,  accordingly,  will file reports  thereunder  with the  Securities and
Exchange  Commission.  The registration  statement and the exhibits thereto, and
reports and other  information  filed by the depositor  pursuant to the Exchange
Act can be inspected and copied at the public reference facilities maintained by
the Securities and Exchange  Commission at 450 Fifth Street,  N.W.,  Washington,
D.C. 20549, and at certain of its Regional  Offices located as follows:  Chicago

Exchange Commission's  Electronic Data Gathering,  Analysis and Retrieval System
at the Securities and Exchange Commission's Web Site (http://www.sec.gov).

                         REPORTS TO CERTIFICATEHOLDERS

     Monthly reports which contain  information  concerning the trust fund for a
series of  certificates  will be sent by or on behalf of the master  servicer or
the trustee to each holder of record of the  certificates of the related series.
See 'Description of the Certificates -- Reports to Certificateholders.'  Reports
forwarded  to  holders  will  contain  financial  information  that has not been
examined or reported upon by an independent  certified  public  accountant.  The
depositor will file with the Securities and Exchange  Commission  those periodic
reports relating to the trust for a series of certificates as are required under
the Exchange Act.

               INCORPORATION OF CERTAIN INFORMATION BY REFERENCE

     The SEC allows the depositor to  'incorporate by reference' the information
filed with the SEC by the depositor,  under Section 13(a), 13(c), 14 or 15(d) of
the  Exchange  Act,  that relates to the trust fund for the  certificates.  This
means that the depositor can disclose  important  information to any investor by
referring  the investor to these  documents.  The  information  incorporated  by
reference is an important part of this prospectus,  and information filed by the
depositor with the SEC that relates to the trust fund for the certificates  will

incorporated  by reference with respect to a particular  series of  certificates
include an insurer's  financials,  a certificate  policy,  mortgage pool policy,
computational  materials,  collateral  term  sheets,  the  related  pooling  and
