THE TRUST
 
The depositor will establish a trust with respect to the Series 1999-S7
Certificates, pursuant to a pooling and servicing agreement dated as of
March 1, 1999 among the depositor, the master servicer and the trustee. On the
closing date, the depositor will deposit the pool of mortgage loans described
below into the trust.
 
Each Series 1999-S7 Certificate will represent a partial ownership interest in
the trust. Distributions of interest and/or principal on the certificates will
be made only from payments received in connection with the mortgage loans
described below.
THE MORTGAGE POOL
The mortgage loans to be deposited into the trust have the following
characteristics as of the cut-off date:

DISTRIBUTIONS ON THE OFFERED CERTIFICATES
Subservicers will collect monthly payments of principal and interest on the
mortgage loans. Each month, the subservicers will retain their subservicing fee
and forward the remainder of the collections, including unscheduled payments, to
the master servicer. After retaining its master servicing fee and amounts that
reimburse the subservicer or master servicer for reimbursable expenses and
advances, the master servicer will forward all collections on the mortgage
loans, together with any advances that it makes for delinquent mortgage
payments, to the trustee.
 
The aggregate amount of such monthly collections and advances is described under
the heading "Description of the Certificates--The Available Distribution Amount"
in this prospectus supplement.
 
Distributions to certificateholders will be made from available amounts as
follows:
 

                    Step 1
    Distribution of interest to the Class A
    Certificates (other than the Class A-P
    Certificates) and Class R Certificates


                    Step 2

  Distribution of principal to the Class A-P
                Certificates(1)


                    Step 3

   Distribution of principal to the Class A
    Certificates (other than the Class A-P
   Certificates) and Class R Certificates(2)


                    Step 4

   Payment to master servicer in respect of
         certain unreimbursed advances


                    Step 5

              Distribution to the
 Class M Certificates in the following order:
    Interest to the Class M-1 Certificates
    Principal to the Class M-1 Certificates
    Interest to the Class M-2 Certificates
    Principal to the Class M-2 Certificates
    Interest to the Class M-3 Certificates
    Principal to the Class M-3 Certificates


                    Step 6

 Distribution of interest and principal to the
             Class B Certificates


                    Step 7

  Distribution of any remaining funds to the
           Residual Certificates(3)
 
- ------------------
(1) The Class A-P Certificates receive only a certain portion of the principal
    received in respect of each mortgage loan that has a net mortgage rate of
    less than 6.50% , as described in "Description of the
    Certificates--Principal Distributions on the Senior Certificates" in this
    prospectus supplement.
 
(2) Not all outstanding classes of Class A Certificates will receive principal
    distributions on each distribution date.
 
(3) It is very unlikely that any distributions will be made to the Class R
    Certificates under Step 7.
 
                                      S-5
<PAGE>
The amount of interest owed to each class of certificates (other than the
Class A-P Certificates) on each distribution date will generally equal:
 
o the pass-through rate set forth above for that class of certificates
 
                                 MULTIPLIED BY
 
o the certificate 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 pro rata share of certain interest shortfalls allocated to that class.
 
See "Description of the Certificates--Interest Distributions" in this prospectus
supplement.
 
Principal distributions on the certificates entitled to principal distributions
will be allocated among the various classes of offered certificates 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. Until the distribution date in April 2004, all
principal prepayments on the mortgage loans will be distributed to the Class A
Certificates (other than the Class A-5 and Class A-V Certificates) and Class R
Certificates (and none to the Class M Certificates), unless the principal
balances of such certificates (other than the Class A-P Certificates) have been
reduced to zero. Not all outstanding Class A Certificates or Class R
Certificates will receive principal on each distribution date. The Class A-V
Certificates are not entitled to receive any principal distributions.
 
See "Description of the Certificates--Principal Distributions on the Senior
Certificates" in this prospectus supplement.
 
CREDIT ENHANCEMENT
 
ALLOCATION OF LOSSES.  Except as described below, if the Class M Certificates or
Class B Certificates remain outstanding, losses on the mortgage loans will be
allocated first to the class of Class M Certificates or Class B Certificates
with the lowest payment priority, and the other classes of certificates will not
bear any portion of such losses.
If none of the Class M Certificates or Class B Certificates remain outstanding,
losses will be allocated among the Class A Certificates (other than the
Class A-P Certificates) and Class R Certificates, in proportion to their
respective remaining principal balances or notional amount, as applicable. A
special allocation provision applies to the Class A-P Certificates.
 
Not all losses will be allocated in the priority set forth above. Losses due to
natural disasters such as floods and earthquakes, fraud by a mortgagor,
bankruptcy of a mortgagor or certain other extraordinary events will be
allocated as described above only up to specified amounts. Losses of these types
in excess of the specified amount will, in general, be allocated to all
outstanding classes of certificates pro rata in proportion to their remaining
principal balances or accrued interest. Therefore, the Class M Certificates and
Class B Certificates do not act as credit enhancement for the Class A
Certificates and Class R Certificates for such losses.
 
Losses on each mortgage loan having a net mortgage rate of less than 6.50% that
are allocable to the Class A Certificates and Class R Certificates will be
allocated first to the Class A-P Certificates in an amount based on the
percentage of each such mortgage loan represented by the Class A-P Certificates.
The remainder of such losses will be allocated as described above.
 
See "Description of the Certificates--Allocation of Losses; Subordination" in
this prospectus supplement.
 
PRIORITY OF DISTRIBUTIONS.  The priority in which distributions are made to
certificateholders also provides credit enhancement for certain classes of
certificates. The priority of distribution is shown in the chart on page S-5.
This manner of distributions ensures that any shortfall (other than specified
amounts of certain types of losses described in this prospectus supplement under
"Description of the Certificates--Allocation of Losses; Subordination") in
amounts owed on the certificates is borne first by the most subordinate class of
certificates.
 
Allocating all or a disproportionately large portion of principal prepayments
and other unscheduled payments of principal to the Class A Certificates and
Class R Certificates in the early years provides additional credit enhancement
for the Class A Certificates and Class R Certificates by preserving a greater
portion of the principal balances of the
 
                                      S-6
<PAGE>
Class M Certificates and Class B Certificates for absorption of losses.
 
ADVANCES
 
For any month, if the master servicer receives no payment on a mortgage loan or
a payment that is less than the full scheduled payment, the master servicer will
advance its own funds to cover that shortfall. However, the master servicer will
make such advance only if it determines that such 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 outstanding 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 may, but will not be
required to:
 
o purchase from the trust all remaining mortgage loans and thereby cause an
  early retirement of the certificates; or
 
o purchase all the certificates.
 
An optional purchase of the outstanding certificates will cause the outstanding
principal balance of the certificates to be paid in full with accrued interest.
However, there will be no reimbursement of principal reductions or related
interest that resulted from losses allocated to the certificates. An optional
purchase of the remaining mortgage loans may cause the holders of one or more
classes of certificates to receive less than the outstanding principal balance
of their certificates plus accrued interest.
 
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 set forth in the table on page S-4 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 is subject to change or withdrawal 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 the Secondary Mortgage Market Enhancement Act of 1984. 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 purchased by persons investing assets of
employee benefit plans or individual retirement accounts subject to important
considerations. Sales of the Class M Certificates and the Class R Certificates
to most such plans or retirement accounts are prohibited, except as may be
permitted under an exemption available to insurance companies using general
accounts. Any investor in a Class M Certificate will be deemed to represent that
it complies 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. Such certificates will generally be treated as representing ownership of
debt for federal income tax purposes. Certificateholders will be required to
include in
 
                                      S-7
<PAGE>
income all interest and original issue discount, if any, on such certificates in
accordance with the accrual method of accounting regardless of the
certificateholders' usual methods of accounting. For federal income tax
purposes, the Class R Certificates will be the residual interest in the trust.
 
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 "Certain 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
accompanying 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:

                                   to properties in that region may experience high rates of loss and
                                   delinquency, resulting in losses to certificateholders. A region's economic
                                   condition and housing market may be adversely affected by a variety of events,
                                   including natural disasters such as earthquakes, hurricanes, floods and
                                   eruptions, and civil disturbances such as riots. The economic impact of any
                                   such events may also be felt in areas beyond the region immediately affected
                                   by the disaster or disturbance. The properties underlying the mortgage loans
                                   may be concentrated in these regions. Such concentration may result in greater
                                   losses to certificateholders than those generally present for similar
                                   mortgage-backed securities without such concentration.

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

SPECIAL YIELD AND PREPAYMENT 
  CONSIDERATIONS
 
An investor's yield to maturity    The yield to maturity on each class of offered certificates will depend on a
will depend on various factors.    variety of factors, including:
                                   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. In general, if a class of certificates is
                                     purchased at a price higher than its outstanding principal balance and
                                     principal distributions on such class occur faster than assumed at the time
                                     of purchase, the yield will be lower than anticipated. Conversely, if a
                                     class of certificates is purchased at a price lower than its outstanding
                                     principal balance and principal distributions on that class occur more
                                     slowly than assumed at the time of purchase, the yield will be lower than
                                     anticipated.
 
The rate of prepayments on the     Since mortgagors can generally prepay their mortgage loans at any time, the
mortgage loans will be affected    rate and timing of principal distributions on the offered certificates are
by various factors.                highly uncertain. Generally, when market interest rates increase, borrowers
                                   are less likely to prepay their mortgage loans. Such reduced prepayments could
                                   result in a slower return of principal to holders of the offered certificates
                                   at a time when they may be able to reinvest such funds at a higher rate of
                                   interest than the pass-through rate on their class of certificates.
                                   Conversely, when market interest rates decrease, borrowers are more likely to
                                   prepay their mortgage loans. Such increased prepayments could result in a
                                   faster return of principal to holders of the offered certificates at a time
                                   when they may not be able to reinvest such funds at an interest rate as high
                                   as the pass-through rate on their 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.

     Class A Certificates          The Class A Certificates are subject to various priorities for payment of
                                   principal as described herein. Distributions of principal on the Class A
                                   Certificates 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. 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 such
                                   classes.
 
                                   See "Description of the Certificates--Principal Distributions on the Senior

       Class A-3, Class A-4,       The Class A-3, Class A-4, Class A-14 and Class A-15 Certificates will accrue
       Class A-14 and Class A-15   interest at an adjusting rate determined separately for each distribution date
       Certificates                according to an index in the manner described in this prospectus supplement
                                   under "Description of the Certificates--Determination of LIBOR." THE INTEREST
                                   RATE ON THE CLASS A-4 CERTIFICATES AND CLASS A-15 CERTIFICATES WILL VARY
                                   INVERSELY WITH A MULTIPLE OF THE INDEX. Therefore, the yield to investors on
                                   the Class A-3 Certificates and Class A-14 Certificates will be sensitive, and
                                   the Class A-4 Certificates and Class A-15 Certificates will be extremely
                                   sensitive, to fluctuations of the index.
 
       Class A-5 Certificates      The Class A-5 Certificates are not expected to receive any distributions of
                                   principal until the distribution date in April 2004. Until the distribution
                                   date in April 2008, the Class A-5 Certificates are expected to receive a
                                   portion of principal payments that is smaller than its pro rata share of
                                   principal payments.
 
       Class A-8 and A-9           Class A-8 and Class A-9 Certificates will receive a portion of principal
       Certificates                payments after certain other classes of Class A Certificates have received
                                   principal payments. Therefore, an investor's yield on such certificates will
                                   be sensitive to the rate and timing of such distributions and such
                                   certificates would not be an appropriate investment for any investor requiring
                                   a distribution of a particular amount of principal or interest on a specific
                                   date or dates. IN ADDITION TO THE CONSIDERATIONS SET FORTH ABOVE, INVESTORS IN
                                   THE CLASS A-8 CERTIFICATES AND CLASS A-9 CERTIFICATES SHOULD BE AWARE THAT
                                   SUCH CERTIFICATES MAY NOT BE AN APPROPRIATE INVESTMENT FOR ALL PROSPECTIVE
                                   INVESTORS.
 
                                   Investors in the Class A-8 Certificates and Class A-9 Certificates should be
                                   aware that such certificates have a later priority of payment with respect to
                                   principal in relation to some of the other classes of Class A Certificates.
                                   Therefore, such certificates are particularly sensitive to the rate and timing
                                   of principal prepayments.

       Class A-10 and Class A-11   The Class A-10 Certificates and Class A-11 Certificates will generally receive
       Certificates                payments of principal on each distribution date in amounts determined by using
                                   the table herein entitled "Planned Principal Balances," assuming that the rate
                                   of prepayments on the mortgage loans are within a range as described under
                                   "Description of the Certificates--Principal Distributions on the Senior
                                   Certificates." However, if prepayments occur at a rate below such range, the
                                   amount of funds available for distribution of principal on such certificates
                                   may not be sufficient to reduce the principal balances thereof to the amounts
                                   set forth in such table, and as a result, the weighted average lives of the
                                   Class A-10 Certificates and Class A-11 Certificates will be extended.
                                   Conversely, if prepayments occur at a rate above such range, and if the
                                   principal balance of certain classes of certificates as described under
                                   "Description of Certificates--Certain Yield and Prepayment Considerations,"
                                   are reduced to zero, the principal balances on such certificates may be
                                   reduced below the amounts set forth in such table, and as a result, the
                                   weighted average lives of such certificates will be reduced.
 
       Class A-14 and Class A-15   Investors in the Class A-14 Certificates and Class A-15 Certificates should be
       Certificates                aware that such certificates may receive varying distributions of principal on
                                   each distribution date to the extent necessary to stabilize the amount of
                                   principal needed to reduce the principal balances of the Class A-10
                                   Certificates and Class A-11 Certificates to the respective amounts set forth
                                   in the table herein entitled "Planned Principal Balances." Due to the
                                   companion nature of the Class A-14 Certificates and Class A-15 Certificates,
                                   such certificates will likely experience price and yield volatility. Investors
                                   should consider whether such volatility is suitable to their investment needs.
 
       Class A-P Certificates      The Class A-P Certificates will receive a portion of the principal payments
                                   only from mortgage loans that have net mortgage rates lower than 6.50%.
                                   Therefore, the yield on the Class A-P Certificates is extremely sensitive to
                                   the rate and timing of principal prepayments and defaults on mortgage loans
                                   that have net mortgage rates lower than 6.50%.
 
                                   Investors in the Class A-P Certificates should be aware that 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 6.50% occur at a rate slower than an
                                   investor assumed at the time of purchase, the investor's yield will be lower
                                   than anticipated.
 
       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 6.50%.
                                   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 6.50%.

                                   Investors in the Class A-V Certificates should be aware that mortgage loans
                                   with higher mortgage rates are more likely to be prepaid than mortgage loans
                                   with lower mortgage rates. If prepayments on the mortgage loans that have net
                                   mortgage rates higher than 6.50% are prepaid at a rate faster than an investor
                                   assumed at the time of purchase, the investor's yield will be lower than
                                   anticipated. 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 6.50% could result in their failure to recover
                                   fully their investments.
 
       Class M Certificates        Losses on the mortgage loans will be allocated among the certificates in the
                                   manner described herein. The yield to investors in the Class M Certificates
                                   will be sensitive to the rate and timing of losses on the mortgage loans.
                                   Losses (other than specified amounts of certain types of losses described
                                   herein) will be allocated to the most subordinate class of Class M
                                   Certificates or Class B Certificates outstanding.
 
                                   See "Summary--Credit Enhancement--Allocation of Losses" and "Description of
                                   the Certificates--Allocation of Losses; Subordination" in this prospectus
                                   supplement.
 
                                   It is not expected that the Class M Certificates will receive any
                                   distributions of principal prepayments until the distribution date in April
                                   2004. After that date, all or a disproportionately large portion of principal
                                   prepayments on the mortgage loans may be allocated to the Class A
                                   Certificates and Class R 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.

                                  INTRODUCTION
 
     Residential Funding Mortgage Securities I, Inc. (the "DEPOSITOR") will
establish a trust (the "TRUST") with respect to Series 1999-S7 on March 30, 1999
(the "CLOSING DATE"), pursuant to a pooling and servicing agreement (the
"POOLING AND SERVICING AGREEMENT") among the Depositor, Residential Funding
Corporation ("RESIDENTIAL FUNDING" or the "MASTER SERVICER") and The First
National Bank of Chicago (the "TRUSTEE"), dated as of March 1, 1999 (the
"CUT-OFF DATE"). On the Closing Date, the Depositor will deposit into the Trust
a pool of mortgage loans (the "MORTGAGE POOL") secured by one- to four-family
residential properties with terms to maturity of not more than 30 years.
 
                        DESCRIPTION OF THE MORTGAGE POOL
 
GENERAL
 
     The Mortgage Pool will consist of 3,923 mortgage loans ("MORTGAGE LOANS")
with an aggregate principal balance outstanding as of the Cut-off Date, after
deducting payments of principal due on such date, of $1,241,857,991. The
Mortgage Loans are secured by first liens on fee simple interests in one- to
four-family residential real properties and, in the case of two Mortgage Loans,
an interest in shares issued by a cooperative apartment corporation and the
related proprietary lease (each, a "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 herein to the date of origination shall be deemed to
be the date of the most recent modification. All percentages of the Mortgage
Loans described herein are approximate percentages (except as otherwise
indicated) by aggregate principal balance as of the Cut-off Date.
 
     All of the Mortgage Loans were purchased by the Depositor through its
affiliate Residential Funding from Unaffiliated Sellers as described herein and
in the Prospectus, except in the case of 16.6% 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 ("HOMECOMINGS"). No Unaffiliated Seller sold more than 8.7% of the
Mortgage Loans to Residential Funding. 73.3% of the Mortgage Loans are being or
will be subserviced by HomeComings.
 
     Pursuant to 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 certain 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 such Mortgage Loan, neither
the Depositor nor Residential Funding will be required to repurchase such
Mortgage Loan unless such breach also constitutes a breach of one of the
Depositor's or Residential Funding's representations and warranties with respect
to such Mortgage Loan and such 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 such Mortgage Loan if the substance of any such breach also
constitutes fraud in the origination of such affected Mortgage Loan. A limited
amount of losses on Mortgage Loans as to which there was fraud in the
origination of such Mortgage Loans will be covered by the Subordination (as
defined herein) provided by the Class M Certificates and Class B Certificates as
described herein under "Description of the Certificates--Allocation of Losses;
Subordination."
 
MORTGAGE POOL CHARACTERISTICS
 
     None of the Mortgage Loans will have been originated prior to October 24,
1997 or will have a maturity date later than March 1, 2029. No Mortgage Loan
will have a remaining term to maturity as of the Cut-off Date of less than 177
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
 
                                      S-14
<PAGE>
Loans as of the Cut-off Date will be approximately 359 months. As used herein
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 such Mortgage Loan to zero, assuming the related Mortgagor will make
all scheduled monthly payments but no prepayments, on such 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" herein.
 
     Approximately 0.03% of the Mortgage Loans will be Buydown Mortgage Loans.
 
     No Mortgage Loan provides for deferred interest or negative amortization.
 
     Certain of the Mortgage Loans may have been underwritten pursuant to a
streamlined refinancing documentation program, which permits certain mortgage
loans to be refinanced with only limited verification or updating of the
underwriting information that was obtained at the time that the refinanced
mortgage loan was underwritten. For example, a new appraisal of a mortgaged
property may not be required if the related refinanced mortgage loan was
originated up to 24 months prior to the refinancing. In addition, a mortgagor's
income may not be verified, although continued employment is required to be
verified. In certain circumstances, a mortgagor may be permitted to increase the
principal amount of a refinancing mortgage loan to 105% of the outstanding
principal balance of the refinanced mortgage loan. Each Mortgage Loan
underwritten pursuant to this program is treated for purposes of the table
entitled "Mortgage Loan Documentation Types," below, as having been underwritten
pursuant to the same underwriting documentation program as the mortgage loan
that it refinanced.
 
     Included below is a table showing the "Credit Scores" for certain
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 Loan-to-Value 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 hereof.

     The weighted average Loan-to-Value Ratio at origination of the Mortgage
Loans which were underwritten under a reduced loan documentation program will be
66.13%. No more than 57.4% of such reduced loan documentation Mortgage Loans
will be secured by Mortgaged Properties located in California.
 
     3.23% of the Mortgage Loans were underwritten pursuant to a streamlined
refinancing documentation program, which permits certain mortgage loans to be
refinanced with only limited verification or updating of underwriting
information obtained at the time that the refinanced mortgaged loan was
underwritten. See "Description of the Mortgage Pool--General" herein.

     Certain aspects of the Cooperative Loans included in the Mortgage Pool
differ from those of other types of Mortgage Loans. See "Certain Legal Aspects
of Mortgage Loans--Cooperative Loans" in the Prospectus.
 
PRIMARY MORTGAGE INSURANCE AND PRIMARY HAZARD INSURANCE
 
     Each Mortgage Loan is required to be covered by a standard hazard insurance
policy (a "PRIMARY HAZARD INSURANCE POLICY"). In addition, to the best of the
Depositor's knowledge, except with respect to one Mortgage Loan representing
approximately 0.02% of the Mortgage Pool, each Mortgage Loan with a
Loan-to-Value Ratio at origination in excess of 80.00% will be insured by a
primary mortgage insurance policy (a "PRIMARY INSURANCE POLICY") covering at
least 25% of the principal balance of the Mortgage Loan at origination if the
Loan-to-Value Ratio is between 95.00 and 90.01% and at least 12% of such balance
if the Loan-to-Value Ratio is between 90.00% and 80.01%. Substantially all of
such Primary Insurance Policies were issued by General Electric Mortgage
Insurance Corporation, Mortgage Guaranty Insurance Corporation, United Guaranty
Residential Insurance Company, PMI Mortgage Insurance Company, Commonwealth
Mortgage Assurance Company, Republic Mortgage Insurance Company or Amerin
Guaranty Corporation (collectively, 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 such 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 such 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 set forth herein 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 certain 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 set forth in the preceding
paragraph, such removal or addition will be noted in the Current Report on Form
8-K.

                        DESCRIPTION OF THE CERTIFICATES
 
GENERAL
 
     The Series 1999-S7 Mortgage Pass-Through Certificates will include the
following eighteen classes (the "SENIOR CERTIFICATES"): (i) Class A-1
Certificates, Class A-2 Certificates, Class A-6 Certificates, Class A-7
Certificates, Class A-12 Certificates and Class A-13 Certificates; (ii) Class
A-3 Certificates and Class A-14 Certificates (the "FLOATER CERTIFICATES"); (iii)
Class A-4 Certificates and Class A-15 Certificates (the "INVERSE FLOATER
CERTIFICATES"; and together with the Floater Certificates, the "ADJUSTABLE RATE
CERTIFICATES"); (iv) Class A-5 Certificates (the "LOCKOUT CERTIFICATES"); (v)
Class A-8 Certificates and Class A-9 Certificates (the "RETAIL CERTIFICATES");
(vi) Class A-10 Certificates and Class A-11 Certificates (the "PAC
CERTIFICATES"); (vii) Class A-P Certificates (the "PRINCIPAL ONLY
CERTIFICATES"); (viii) Class A-V Certificates (the "VARIABLE STRIP
CERTIFICATES"); and (ix) Class R Certificates (the "RESIDUAL CERTIFICATES"). The
Class A-14 Certificates and Class A-15 Certificates are collectively referred to
herein as the "COMPANION CERTIFICATES." In addition to the Senior Certificates,
the Series 1999-S7 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 and Class M-3 Certificates (collectively,
the "CLASS M CERTIFICATES") and the Class B-1 Certificates, Class B-2
Certificates and Class B-3 Certificates (collectively, the "CLASS B
CERTIFICATES" and, together with the Class M Certificates and Senior
Certificates, the "CERTIFICATES"). Only the Senior Certificates and Class M
Certificates (together, the "OFFERED CERTIFICATES") are offered hereby. See
"Index of Principal Definitions" in the Prospectus for the meanings of
capitalized terms and acronyms not otherwise defined herein.
 
     The Certificates will evidence the entire beneficial ownership interest in
the Trust. The Trust will consist of: (i) the Mortgage Loans; (ii) such assets
as from time to time are identified as deposited in respect of the Mortgage
Loans in the Custodial Account and in the Certificate Account and belonging to
the Trust; (iii) property acquired by foreclosure of such Mortgage Loans or deed
in lieu of foreclosure; (iv) any applicable Primary Insurance Policies and
Primary Hazard Insurance Policies; and (v) all proceeds of any of the foregoing.
 
     The Senior Certificates will evidence in the aggregate an initial
beneficial ownership interest of approximately 96.00% 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 2.10%, 0.75%, 0.40%, 0.30%, 0.20% and 0.25%, respectively, in the
Trust.
 
     The Principal Only Certificates will be entitled to payments based on the
Discount Fraction of the Discount Mortgage Loans. A "DISCOUNT MORTGAGE LOAN" is
any Mortgage Loan with a Net Mortgage Rate less than 6.50% per annum. With
respect to each Discount Mortgage Loan, the "DISCOUNT FRACTION" is equal to a
fraction, expressed as a percentage, the numerator of which is 6.50% minus the
Net Mortgage Rate for such Discount Mortgage Loan and the denominator of which
is 6.50%. The Mortgage Loans other than the Discount Mortgage Loans are referred
to herein as the "NON-DISCOUNT MORTGAGE LOANS."
 
     The Senior Certificates (other than the Principal Only, Variable Strip and
Residual Certificates) and the Class M Certificates (together, the "DTC
REGISTERED CERTIFICATES") will be available only in book-entry form through
facilities of The Depository Trust Company ("DTC"). The DTC Registered
Certificates will be issued, maintained and transferred on the book-entry
records of DTC and its Participants. The DTC Registered Certificates, other than
the Retail 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 Retail Certificates will be
issued in minimum denominations of $1,000 and integral multiples of $1,000 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 Certificate, as otherwise set forth
herein under "Certain 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. ("CEDE"). No
Beneficial Owner will be entitled to receive a certificate of such class in
fully registered form (a
 
                                      S-21
<PAGE>
"DEFINITIVE CERTIFICATE"), except as set forth below 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 herein, 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
all references herein 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 ("SYSTEMS") that
are dependent upon calendar dates, including dates before, on and after January
1, 2000, may encounter "YEAR 2000" problems. DTC has informed its Participants
and other members of the financial community (the "INDUSTRY") that it has
developed and is implementing a program so that its Systems, as they relate to
the timely payment of distributions (including principal and income payments) to
securityholders, book-entry deliveries and settlement of trades with DTC ("DTC
SERVICES") 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 the Industry, 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 the
Industry that it is contacting (and will continue to contact) third party
vendors from whom DTC acquires services to (i) impress upon them the importance
of such services being Year 2000 compliant; and (ii) determine the extent of
their efforts for Year 2000 remediation (and, as appropriate, testing) of their
services. In addition, DTC is in the process of developing such contingency
plans as it deems appropriate.
 
     According to DTC, the foregoing information with respect to DTC has been
provided to the Industry 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 such 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 such 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 (the "RULES"), 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, such DTC Registered
Certificates. Participants and Indirect Participants with which Beneficial
Owners have accounts with respect to such DTC Registered Certificates similarly
are required to make book-entry transfers and receive and transmit such
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, the 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
 
                                      S-22

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 set forth 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 surrender by DTC of the definitive certificates representing the DTC
Registered Certificates and 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 such 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.
 
AVAILABLE DISTRIBUTION AMOUNT
 
     The "AVAILABLE DISTRIBUTION AMOUNT" for any Distribution Date is equal to
(i) 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
(collectively, the "SERVICING FEES"), (ii) certain 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 (iii) all
Advances made for such 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 herein under
"--Principal Distributions on the Senior Certificates," any such 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, (i) the "DUE DATE" is the
first day of the month in which such Distribution Date occurs and (ii) the
"DETERMINATION DATE" is the 20th day of the month in which such Distribution
Date occurs or, if such day is not a business day, the immediately succeeding
business day.
 
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 such class on each Distribution
Date, to the extent of the Available Distribution Amount for such 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 such class on each
Distribution Date, to the extent of the Available Distribution Amount for such
Distribution Date after distributions of interest and principal to the Senior
Certificates, reimbursements for certain Advances to the Master Servicer and
distributions of interest and principal to any class of Class M Certificates
having a higher payment priority.
 
     With respect to any Distribution Date, "ACCRUED CERTIFICATE INTEREST" will
be 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 such class immediately prior to such 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 such Distribution Date at the
then-applicable Pass-Through Rate on such class for such Distribution Date; in
each case less interest shortfalls, if any, allocated thereto for such
Distribution Date to
 
                                      S-23
<PAGE>
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 (as defined below) to the extent
     not covered by the Master Servicer as described below;
 
          (ii) the interest portions of Realized Losses (including Special
     Hazard Losses in excess of the Special Hazard Amount ("EXCESS SPECIAL
     HAZARD LOSSES"), Fraud Losses in excess of the Fraud Loss Amount ("EXCESS
     FRAUD LOSSES"), Bankruptcy Losses in excess of the Bankruptcy Amount
     ("EXCESS BANKRUPTCY LOSSES") and losses occasioned by war, civil
     insurrection, certain governmental actions, nuclear reaction and certain
     other risks ("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 Relief Act or similar
     legislation or regulations, all allocated as described below.
 
Such 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 such Distribution Date absent such
reductions. In the case of each class of Class M Certificates, Accrued
Certificate Interest on such class will be further reduced by the allocation of
the interest portion of certain losses thereto, if any, as described below under
"--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. The Principal Only
Certificates are not entitled to distributions of interest.
 
     The "INTEREST ACCRUAL PERIOD" for all classes of Certificates (other than
the Class A-3 Certificates and Class A-4 Certificates) is the calendar month
preceding the month in which such Distribution Date occurs. The Interest Accrual
Period for the Class A-3 Certificates and Class A-4 Certificates is the
one-month period commencing on the 25th day of the month preceding the month in
which such Distribution Date occurs and ending on the 24th day of the month in
which such Distribution Date occurs. Notwithstanding the foregoing, the
distributions of interest on any Distribution Date for all classes of
Certificates, including the Class A-3 Certificates and Class A-4 Certificates,
will reflect interest accrued, and receipts with respect thereto, 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 herein.
 
     The "PREPAYMENT INTEREST SHORTFALL" for any Distribution Date is equal to
the aggregate shortfall, if any, in collections of interest (adjusted to the
related Net Mortgage Rates) resulting from Mortgagor prepayments on the Mortgage
Loans during the preceding calendar month. Such 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 such
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 such
Prepayment Interest Shortfalls do not exceed an amount equal to the lesser of
(a) one-twelfth of 0.125% of the Stated Principal Balance (as defined herein) of
the Mortgage Loans immediately preceding such Distribution Date and (b) the sum
of the master servicing fee payable to the Master Servicer in respect of its
master servicing activities and reinvestment income received by the Master
Servicer on amounts payable with respect to such 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"
herein.
 
     If on any Distribution Date the Available Distribution Amount is less than
Accrued Certificate Interest on the Senior Certificates for such Distribution
Date, the shortfall will be allocated among the holders of all classes
 
                                      S-24
<PAGE>
of Senior Certificates in proportion to the respective amounts of Accrued
Certificate Interest for such 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 third
preceding paragraph) will be unpaid Accrued Certificate Interest and will be
distributable to holders of the Certificates of such classes entitled to such
amounts on subsequent Distribution Dates, in each case, to the extent of
available funds after interest distributions as required herein. Such 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 such 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 set forth on page S-4 hereof.
 
     The Pass-Through Rates on the Adjustable Rate Certificates are calculated
as follows:
 
          (1) The Pass-Through Rate on the Class A-3 Certificates with respect
     to the initial Interest Accrual Period is 5.9500% per annum, and as to any
     Interest Accrual Period thereafter, will be a per annum rate equal to 1.00%
     plus the arithmetic mean of the London interbank offered rate quotations
     for one-month Eurodollar deposits, determined monthly as set forth herein
     ("LIBOR") (subject to a maximum rate of 8.00% per annum and a minimum rate
     of 1.00% per annum).
 
          (2) The Pass-Through Rate on the Class A-4 Certificates with respect
     to the initial Interest Accrual Period is 8.88333341% per annum, and as to
     any Interest Accrual Period thereafter, will be a per annum rate equal to
     30.3333335800% minus the product of LIBOR and 4.3333333700 (subject to a
     maximum rate of 30.3333335800% per annum and a minimum rate of 0.00% per
     annum).
 
          (3) The Pass-Through Rate on the Class A-14 Certificates with respect
     to the initial Interest Accrual Period is 5.4500% per annum, and as to any
     Interest Accrual Period thereafter, will be a per annum rate equal to 0.50%
     plus LIBOR (subject to a maximum rate of 8.50% per annum and a minimum rate
     of 0.50% per annum).
 
          (4) The Pass-Through Rate on the Class A-15 Certificates with respect
     to the initial Interest Accrual Period is 9.9125% per annum, and as to any
     Interest Accrual Period thereafter, will be a per annum rate equal to
     26.00% minus the product of LIBOR and 3.25 (subject to a maximum rate of
     26.00% 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 (312) 407-4660.
 
     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 such 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 the Net Mortgage Rate thereon minus 6.50%
(but not less than 0.00%). The "NET MORTGAGE RATE" on each Mortgage Loan is
equal to the Mortgage Rate thereon minus the rate per annum at which the related
master servicing and subservicing fees accrue (the "SERVICING FEE RATE"). As of
the Cut-off Date, the Pool Strip Rates on the Mortgage Loans range between 0.00%
and 2.045% per annum. The initial Pass-Through Rate on the Variable Strip
Certificates is approximately 0.3059% per annum.
 
     As described herein, the Accrued Certificate Interest allocable to each
class of Certificates (other than the Principal Only Certificates, which are not
entitled to distributions in respect of interest) is based on the Certificate
Principal Balance thereof or, in the case of the Variable Strip Certificates, on
the Notional Amount. The "CERTIFICATE PRINCIPAL BALANCE" of any Offered
Certificate as of any date of determination is equal to the initial Certificate
Principal Balance thereof, reduced by the aggregate of (a) all amounts allocable
to principal previously distributed with respect to such Certificate and
(b) any reductions in the Certificate Principal Balance thereof deemed to have
occurred in connection with allocations of Realized Losses in the manner
described herein, 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
 
                                      S-25
<PAGE>
(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.
 
     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 such date. At the option of the initial
holder of the Variable Strip Certificates, any Variable Strip Certificate can be
exchanged by such 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 such Variable Strip Certificate. Reference to a Notional
Amount with respect to any Variable Strip Certificate is solely for convenience
in certain calculations and does not represent the right to receive any
distributions allocable to principal.
 
DETERMINATION OF LIBOR
 
     LIBOR for any Interest Accrual Period after the initial Interest Accrual
Period will be determined as described below.
 
     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 such Interest Accrual Period ("LIBOR RATE ADJUSTMENT DATE").
"TELERATE SCREEN PAGE 3750" means the display designated as page 3750 on the
Telerate Service (or such other page as may replace page 3750 on that service
for the purpose of displaying London interbank offered rates of major banks). If
such rate does not appear on such page (or such other page as may replace that
page on that service, or if such service is no longer offered, such 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) 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 such quotations are provided, the rate will be the
arithmetic mean of the quotations. If on such 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
such 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 such
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, 4.950% with
respect to the Adjustable Rate Certificates; provided however, if, under the
priorities described above, 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
 
     Except as provided below, holders of the Senior Certificates (other than
the Variable Strip Certificates, which are not entitled to distributions of
principal, and the Principal Only Certificates) will be entitled to receive on
each Distribution Date, in the priority set forth herein and to the extent of
the portion of the Available Distribution Amount remaining after the aggregate
amount of Accrued Certificate Interest to be distributed to the
 
                                      S-26
<PAGE>
holders of the Senior Certificates for such Distribution Date (the "SENIOR
INTEREST DISTRIBUTION AMOUNT") and the Principal Only Distribution Amount (as
defined below) are distributed, a distribution allocable to principal equal to
the sum of the following:
 
          (i) the product of (A) the then-applicable Senior Percentage (as
     defined below) 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 such 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, as defined below (other than the related
        Discount Fraction of the principal portion of such 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, certain amounts
        representing a principal adjustment) (other than the related Discount
        Fraction of the principal portion of such proceeds, with respect to each
        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 (as defined below) 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 portion of
        such unscheduled collections, with respect to each Discount Mortgage
        Loan);
 
          (ii) in connection with the Final Disposition of a Mortgage Loan
     (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 such Mortgage Loan (other than the related Discount Fraction
        of such Stated Principal Balance, with respect to a Discount Mortgage
        Loan); and
 
             (2) the then-applicable Senior Accelerated Distribution Percentage
        (as defined below) of the related unscheduled collections, including
        Insurance Proceeds and Liquidation Proceeds, to the extent applied as
        recoveries of principal (in each case other than the portion of such
        collections, with respect to a Discount Mortgage Loan, included in
        clause (iii) of the definition of "Principal Only Distribution Amount"
        below);
 
          (iii) the then-applicable Senior Accelerated Distribution Percentage
     of the aggregate of all full and partial Mortgagor prepayments made by the
     respective Mortgagors of the Mortgage Loans during the preceding calendar
     month (other than the related Discount Fraction of such Mortgagor
     prepayments, with respect to each Discount Mortgage Loan);
 
          (iv) any Excess Subordinate Principal Amount (as defined below) for
     such 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 such amounts are not attributable to
     Realized Losses which were allocated to the Class M Certificates or
     Class B Certificates.
 
     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 the amounts described in clauses (i) through (v) of the immediately
preceding paragraph is hereinafter referred to as the "SENIOR PRINCIPAL
DISTRIBUTION 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 such class or classes, the "EXCESS SUBORDINATE PRINCIPAL AMOUNT" is
equal to the amount, if any, by which (i) the amount that would otherwise be
distributable in respect of principal on such class or classes of Certificates
on such Distribution Date is greater than (ii) the excess, if any, of the
aggregate Certificate Principal Balance of such class or classes of Certificates
immediately prior to such Distribution Date over the aggregate
 
                                      S-27
<PAGE>
amount of Realized Losses to be allocated to such class or classes of
Certificates on such Distribution Date, as reduced by any amount calculated
pursuant to clause (v) of the definition of "Principal Only Distribution
Amount."
 
     Holders of the Principal Only Certificates will be entitled to receive on
each Distribution Date, to the extent of the excess, if any, of the Available
Distribution Amount remaining after the Senior Interest Distribution Amount is
distributed, a distribution allocable to principal (the "PRINCIPAL ONLY
DISTRIBUTION AMOUNT") 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, certain
     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 such Discount Mortgage Loan immediately prior to such
     Distribution Date and (b) the aggregate amount of collections on such
     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) with respect to each Final Disposition of a Discount Mortgage Loan
     in connection with such Distribution Date or any prior Distribution Date,
     to the extent that the amount included under clause (iii) above for such
     Distribution Date was less than the amount described in (a) under clause
     (iii) above (each such shortfall, a "PRINCIPAL ONLY COLLECTION SHORTFALL"),
     an amount equal to the aggregate of the Principal Only Collection
     Shortfalls, less any amounts paid pursuant to this clause on a prior
     Distribution Date, until paid in full; provided, that distributions
     pursuant to this clause (v) shall only be made to the extent of Eligible
     Funds (as described below) on any Distribution Date.
 
     A "FINAL DISPOSITION" of a defaulted Mortgage Loan 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 such Mortgage Loan.
 
     "ELIGIBLE FUNDS" on any Distribution Date means 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) thereof), the Principal Only
Distribution Amount (determined without regard to clause (v) thereof) and the
aggregate amount of Accrued Certificate Interest on the Class M, Class B-1 and
Class B-2 Certificates. Notwithstanding any other provision hereof, any
distribution in respect of 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 such Distribution Date on (i) first, 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.
 
     The "STATED PRINCIPAL BALANCE" of any Mortgage Loan as of any date of
determination is equal to the principal balance thereof as of the Cut-off Date,
after application of all scheduled principal payments due on or before the
Cut-off Date, whether or not received, reduced by all amounts allocable to
principal that have been distributed to Certificateholders with respect to such
Mortgage Loan on or before such date, and as further reduced to the extent that
any Realized Loss thereon has been allocated to one or more classes of

     The "SENIOR PERCENTAGE," which initially will equal approximately 95.99%
and will in no event exceed 100%, will be recalculated for each Distribution
Date to be the percentage equal to the aggregate Certificate Principal Balance
of the Senior Certificates (other than the Principal Only Certificates)
immediately prior to such 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 such Distribution Date. The
"SUBORDINATE PERCENTAGE" as of any date of determination is equal to 100% minus
the Senior Percentage as of such date. The initial Senior Percentage is less
than the initial percentage interest in the Trust evidenced by the Senior
Certificates in the aggregate because such 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.
 
     The "SENIOR ACCELERATED DISTRIBUTION PERCENTAGE" for any Distribution Date
occurring prior to the Distribution Date in April 2004 will equal 100%. The
Senior Accelerated Distribution Percentage for any Distribution Date occurring
after the first five years following the Closing Date will be as follows:
 
          (i) for any Distribution Date during the sixth year after the Closing
     Date, the Senior Percentage for such Distribution Date plus 70% of the
     Subordinate Percentage for such Distribution Date;
 
          (ii) for any Distribution Date during the seventh year after the
     Closing Date, the Senior Percentage for such Distribution Date plus 60% of
     the Subordinate Percentage for such Distribution Date;
 
          (iii) for any Distribution Date during the eighth year after the
     Closing Date, the Senior Percentage for such Distribution Date plus 40% of
     the Subordinate Percentage for such Distribution Date;
 
          (iv) for any Distribution Date during the ninth year after the Closing
     Date, the Senior Percentage for such Distribution Date plus 20% of the
     Subordinate Percentage for such Distribution Date; and
 
          (v) for any Distribution Date thereafter, the Senior Percentage for
     such Distribution Date.
 
If on any Distribution Date the Senior Percentage exceeds the initial Senior
Percentage, the Senior Accelerated Distribution Percentage for such Distribution
Date will once again equal 100%.
 
     Any scheduled reduction to the Senior Accelerated Distribution Percentage
described above 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
 
          (ii) Realized Losses on the Mortgage Loans to date for such
     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 (the "ORIGINAL SUBORDINATE PRINCIPAL BALANCE"); 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 such
     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 Original Subordinate
     Principal Balance.
 
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%. See
"Subordination" in the Prospectus.

     The "LOCKOUT DISTRIBUTION PERCENTAGE" for any Distribution Date occurring
prior to the Distribution Date in April 2004 will be equal to 0%. The Lockout
Distribution Percentage for any Distribution Date occurring after the first five
years following the Closing Date will be as follows: for any Distribution Date
during the sixth year after the Closing Date, 30%; for any Distribution Date
during the seventh year after the Closing Date, 40%; for any Distribution Date
during the eighth year after the Closing Date, 60%; for any Distribution Date
during the ninth year after the Closing Date, 80%; and for any Distribution Date
thereafter, 100%.
 
     Distributions of principal on the Senior Certificates on each Distribution
Date will be made (after distribution of the Senior Interest Distribution Amount
as described under "Interest Distributions"), as follows:
 
          (a) Prior to the occurrence of the Credit Support Depletion Date (as
     defined below),
 
             (i) the Principal Only Distribution Amount shall be distributed to
        the Principal Only Certificates, until such Certificate Principal
        Balance has been reduced to zero;
 
             (ii) the Lockout Distribution 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 Senior Certificates (other than the Principal Only
        Certificates)) of the Senior Principal Distribution Amount shall be
        distributed to the Lockout Certificates until the Certificate Principal
        Balance thereof has been reduced to zero;
 
             (iii) the balance, if any, of the Senior Principal Distribution
        Amount remaining after the distribution described in clause (ii) above,
        shall be distributed to the Residual Certificates, until the Certificate
        Principal Balance thereof has been reduced to zero;
 
             (iv) 38.0550006097% of the balance of the Senior Principal
        Distribution Amount remaining after the distributions described in

        of priority:
 
                (A) first, concurrently as follows:
 
                    (1) 73.9764955708% to the Class A-6 Certificates, until the
               Certificate Principal Balance thereof has been reduced to zero;
               and
 
                    (2) 26.0235044292%, concurrently as follows:
 
                        (i) 42.6520000000%, first, to the Class A-12
                   Certificates, and then, to the Class A-13 Certificates, until
                   the Certificate Principal Balances thereof have been reduced
                   to zero; and

                       Certificate Principal Balance thereof has been reduced to
                       its Planned Principal Balance (as set forth in the table
                       below entitled "Planned Principal Balances") for such
                       Distribution Date;

                       been reduced to zero;
 
                            (d) fourth, to the Class A-10 Certificates (without

                       Balance thereof has been reduced to zero; and
 
                            (e) fifth, to the Class A-11 Certificates (without
                       regard to its Planned Principal Balance for such
                       Distribution Date), until the Certificate Principal
                       Balance thereof has been reduced to zero; and

                (B) second, concurrently on a pro rata basis, to the Class A-8
           Certificates and Class A-9 Certificates, until the Certificate
           Principal Balances thereof have been reduced to zero;
 
             (v) 61.9449993903% of the balance of the Senior Principal
        Distribution Amount remaining after the distributions described in
        clauses (ii) and (iii) above shall be distributed in the following order
        of priority:
 
                (A) first, concurrently, 38.0272102412% to the Class A-1
           Certificates, 9.3634240656% to the Class A-2 Certificates and

           the Certificate Principal Balances thereof have been reduced to zero;
           and
 
                (C) third, concurrently on a pro rata basis, to the Class A-3

     all priorities relating to distributions as described above in respect of
     principal among the Senior Certificates (other than the Principal Only
     Certificates) will be disregarded and an amount equal to the Discount
     Fraction of the principal portion of scheduled or unscheduled payments
     received or advanced in respect of Discount Mortgage Loans will be
     distributed to the Principal Only Certificates, and the Senior Principal
     Distribution Amount will be distributed to the Senior Certificates (other
     than the Principal Only 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 thereon 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 herein.
 
     The "CREDIT SUPPORT DEPLETION DATE" is the first Distribution Date on which
the Senior Percentage equals 100%.
 
     The following table sets forth for each Distribution Date the Planned
Principal Balances for the PAC Certificates.
 
     THERE IS NO ASSURANCE THAT SUFFICIENT FUNDS WILL BE AVAILABLE ON ANY
DISTRIBUTION DATE TO REDUCE THE CERTIFICATE PRINCIPAL BALANCES OF THE PAC
CERTIFICATES TO THE PLANNED PRINCIPAL BALANCES FOR SUCH DISTRIBUTION DATE, OR
THAT DISTRIBUTIONS THEREON WILL NOT BE MADE IN EXCESS OF SUCH AMOUNTS FOR SUCH
DISTRIBUTION DATE.

     The Planned Principal Balance for each Distribution Date set forth in the
table above were calculated based on certain assumptions, including the
assumption that prepayments on the Mortgage Loans occur each month at a constant
level between approximately 100% PSA and approximately 400% PSA. The performance
of the Mortgage Loans may differ from the assumptions used in determining the
Planned Principal Balance. The Planned Principal Balance set forth in the table
above are final and binding regardless of any error or alleged error in making
such calculations.
 
     There can be no assurance that funds available for distributions of
principal in reduction of the Certificate Principal Balances of the PAC
Certificates will be sufficient or will not be in excess of amounts needed to
reduce such Certificate Principal Balances to the related Planned Principal
Balance for any Distribution Date. Distributions in reduction of the Certificate
Principal Balance of any class of PAC Certificates may commence significantly
earlier (other than as to a class for which the above table reflect a
distribution on the first Distribution Date) or later than the first
Distribution Date for such class shown in the table above. Distributions of
principal in reduction of the Certificate Principal Balance of any of the PAC
Certificates may end significantly earlier or later than the last Distribution
Date for such class shown in the above table. See "Prepayment and Yield
Considerations" herein for a further discussion of the assumptions used to
produce the above table and the effect of prepayments on the Mortgage Loans on
the rate of payments of principal and on the weighted average lives of such
Certificates.
 
     The Master Servicer may elect to treat Insurance Proceeds, Liquidation
Proceeds and other unscheduled collections (not including prepayments by the
Mortgagors) received in any calendar month as included in the Available
Distribution Amount and the Senior Principal Distribution Amount for the
Distribution Date in the month of receipt, but is not obligated to do so. If the
Master Servicer so elects, such amounts will be deemed to have been received
(and any related Realized Loss shall be deemed to have occurred) on the last day
of the month prior to the receipt thereof.
 
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 (a) the sum of the Senior Interest
Distribution Amount, Principal Only Distribution Amount and Senior Principal
Distribution Amount is distributed, (b) reimbursement is made to the Master
Servicer for certain Advances remaining unreimbursed following the final
liquidation of the related Mortgage Loan to the extent described below under
"ADVANCES," (c) 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 such Distribution Date is distributed to holders of
such class of Class M Certificates and (d) the aggregate amount of Accrued
Certificate Interest required to be distributed to such class of Class M
Certificates on such Distribution Date is distributed to such 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
     (as defined below) 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 such 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 Discount Fraction of the
        principal portion of such 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, certain amounts
        representing a principal adjustment) (other than the related Discount
        Fraction of the principal portion of such 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
 
                                      S-35
<PAGE>
        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
        such unscheduled collections, with respect to a Discount Mortgage Loan);
 
          (ii) such 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
     such 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 such Mortgagor prepayments with respect to a
     Discount Mortgage Loan) made by the respective Mortgagors during the
     preceding calendar month allocable to such class of Class M Certificates as
     described below;
 
          (iv) if such 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 such 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 herein to "payment priority" of the Class M Certificates refer
to a payment priority among such 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 such 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 such 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 such 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 such class and each class, if any, subordinate thereto.
 
     The Class M-1, Class M-2 and Class M-3 Percentages (each, a "CLASS M
PERCENTAGE"), which initially will equal approximately 2.10%, 0.75% and 0.40%,
respectively, and will in no event exceed 100%, 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 such
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 such 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.
 
     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
 
                                      S-36
<PAGE>
before the end of such period), and will thereafter equal 100% whenever the
Senior Percentage exceeds the initial Senior Percentage. Furthermore, as set
forth herein, 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
are subject to postponement based on 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 thereafter. See "--Principal
Distributions on the Senior Certificates" herein.
 
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 (each as defined in the Prospectus) and Special Hazard Losses (as defined
herein). Any such Realized Losses which are not Excess Special Hazard Losses,
Excess Fraud Losses, Excess Bankruptcy Losses or Extraordinary Losses will be
allocated as follows: first, to the Class B Certificates in reverse order of
their numerical designation; second, to the Class M-3 Certificates; third, to
the Class M-2 Certificates; and fourth, to the Class M-1 Certificates, in each
case until the Certificate Principal Balance of such class of Certificates has
been reduced to zero; and thereafter, if any such 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 such Realized Loss, and
the remainder of such Realized Losses and the entire amount of such 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 the
Certificate Principal Balance thereof, in the case of the principal portion of
such Realized Loss, in each case until the Certificate Principal Balance of such
class has been reduced to zero, and the Accrued Certificate Interest thereon, in
the case of the interest portion of such Realized Loss, by the amount so
allocated as of the Distribution Date occurring in the month following the
calendar month in which such Realized Loss was incurred. In addition, any such
allocation of a Realized Loss to a Class M Certificate may also be made by
operation of the payment priority to the Senior Certificates set forth under
"--Principal Distributions on the Senior Certificates" and any class of Class M
Certificates with a higher payment priority. As used herein, "DEBT SERVICE
REDUCTION" means a reduction in the amount of the monthly payment due to certain
bankruptcy proceedings, but does not include any permanent forgiveness of
principal. As used herein, "SUBORDINATION" refers to the provisions discussed
above for the sequential allocation of Realized Losses among the various
classes, as well as all provisions effecting such allocations including the
priorities for distribution of cash flows in the amounts described herein.
 
     As described in the Prospectus, under certain circumstances the Master
Servicer may permit the modification of a defaulted Mortgage Loan to reduce the
applicable Mortgage Rate or to reduce the outstanding principal amount thereof
(a "SERVICING MODIFICATION"). Any such principal reduction shall constitute a
Realized Loss at the time of such reduction, and the amount by which each
Monthly Payment is reduced by any such 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 herein. 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. As used herein, the
Mortgage Rate and Net Mortgage Rate as to any Mortgage Loan will not be reduced
by any 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
herein, 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
 
                                      S-37
<PAGE>
level of Subordination, as such term is defined herein, 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
herein. 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 such losses. Such allocation of principal losses on
the Discount Mortgage Loans may result in such losses being allocated in an
amount that is greater or less than would have been the case had such 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 herein.
 
     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 such Distribution Date, shortfalls
in distributions of principal on any class of Class M Certificates could occur
under certain circumstances, even if such 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 such 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 such losses on Discount Mortgage Loans will be allocated to
the Principal Only Certificates in an amount equal to the related Discount
Fraction thereof, and the remainder of such 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 such class of Certificates on the basis
of its then outstanding Certificate Principal Balance prior to giving effect to
distributions to be made on such 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 such Distribution Date in the case of an
allocation of the interest portion of a Realized Loss.
 
     With respect to any defaulted Mortgage Loan that is finally liquidated,
through foreclosure sale, disposition of the related Mortgaged Property if
acquired on behalf of the Certificateholders by deed in lieu of foreclosure, or
otherwise, the amount of loss realized, if any, will equal the portion of the
Stated Principal Balance remaining, if any, plus interest thereon through the
last day of the month in which such Mortgage Loan was finally liquidated, after
application of all amounts recovered (net of amounts reimbursable to the Master
Servicer or the related Subservicer for Advances and expenses, including
attorneys' fees) towards interest and principal owing on the Mortgage Loan. Such
amount of loss realized and any Special Hazard Losses, Fraud Losses and
Bankruptcy Losses are referred to herein as "REALIZED LOSSES."
 
     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 of the holders of the Class M Certificates and
Class B Certificates, to the extent necessary to satisfy the
 
                                      S-38
<PAGE>
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 such 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 above
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 such 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 herein, also has the effect during certain
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 such class of the Class M Certificates by the Class B
Certificates and any class of Class M Certificates with a lower payment
priority.
 
     The aggregate amount of Realized Losses which may be allocated in
connection with Special Hazard Losses (the "SPECIAL HAZARD AMOUNT") through
Subordination shall initially be equal to $12,418,580. As of any date of
determination following the Cut-off Date, the Special Hazard Amount shall equal
$12,418,580 less the sum of (A) any amounts allocated through Subordination in
respect of Special Hazard Losses and (B) the Adjustment Amount. The Adjustment
Amount will be equal to an amount calculated pursuant to the terms of the
Pooling and Servicing Agreement. As used in this Prospectus Supplement, "Special
Hazard Losses" has the same meaning set forth in the Prospectus, except that
Special Hazard Losses will not include and the Subordination will not cover
Extraordinary Losses, and Special Hazard Losses will not exceed the lesser of
the cost of repair or replacement of the related Mortgaged Properties.
 
     The aggregate amount of Realized Losses which may be allocated in
connection with Fraud Losses (the "FRAUD LOSS AMOUNT") through Subordination
shall initially be equal to $12,418,580. 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 such 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 such 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 aggregate amount of Realized Losses which may be allocated in
connection with Bankruptcy Losses (the "BANKRUPTCY AMOUNT") through
Subordination will initially be equal to $379,969. 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 pursuant to the
terms of the Pooling and Servicing
 
                                      S-39
<PAGE>
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 such 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 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
either (A) the related Mortgage Loan is not in default with regard to payments
due thereunder or (B) 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 in respect of such 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 are
subject to further reduction 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.
 
     Such 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 such
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
such 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 such 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 such
losses will be allocated as described herein. 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 such 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 such reimbursement is covered by amounts otherwise
distributable to such classes, and then by the holders of such 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 Year 2000 ("Y2K") issue is the term generally 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 on or after January 1, 2000. The responsibilities of
Residential Funding as the Master Servicer include collecting payments from the
Subservicers in respect of the Mortgage Loans, calculating the Available
Distribution Amount for each Distribution Date, remitting such 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 (the "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 is being applied to information
technology and non-information technology components ("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-41
<PAGE>
     The six phases by which the Y2K Project Team 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 such Components.

Phase II--Inventory.............................  To (i) create an inventory of all Components and
                                                  (ii) assess the Y2K risks associated with such
                                                  Components.

Phase III--Assessment...........................  To (i) determine which Components are not
                                                  Y2K-ready and (ii) decide whether such
                                                  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 have been, and will be, employed by the Y2K Project
Team.
 
Y2K PROJECT STATUS
 
     As of November 30, 1998, the Y2K Project Team had substantially completed
the six phases for internal "mission critical" Components. However, several
software applications used by Residential Funding in its role as Master Servicer
are still in the final three phases of the six-phase management plan described
above. Residential Funding expects that all phases with respect to such
applications will be substantially completed by March 31, 1999.
 
     The Y2K Project Team anticipates that its efforts with respect to all
internal Components will be substantially complete by March 31, 1999. This
includes substantial completion of (i) renovation and validation of any
non-mission critical Components that the Y2K Project Team and related business
units determine to be necessary, (ii) validation of any remaining "mission
critical" Components that are either completing in-house remediation or waiting
for a vendor upgrade, and (iii) Y2K business continuity planning activities
discussed below.
 
     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
certain depositary institutions, as well as their respective suppliers and
vendors. Accordingly, Residential Funding is communicating with certain 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 (i) has not provided Residential Funding appropriate
documentation supporting its Y2K efforts, (ii) has not
 
                                      S-42
<PAGE>
responded in a timely manner to Residential Funding's inquiries regarding their
Y2K efforts or (iii) does not expect to be Y2K-ready until after June 30, 1999,
has been, and will be, placed in an "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.
 
     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 December 15, 1998, Residential Funding had substantially completed
Phases I and II of its business continuity plan. Residential Funding anticipates
that Phase III will be substantially complete by March 31, 1999 and Phase IV
will be substantially complete by June 30, 1999.
 
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 (i) collect (and
monitor any Subservicer's collection of) payments on the Mortgage Loans, (ii)
distribute such collections to the Trustee and (iii) provide reports to
Certificateholders as set forth herein. 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. Generally,
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 certain risks and uncertainties. Important factors
that could cause results to differ materially from such 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 such 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, among other factors, the rate and
timing of principal payments on the Mortgage Loans and the amount and timing of
Mortgagor defaults resulting in Realized Losses. Such 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 such Mortgage
Loans will in turn be affected by the amortization schedules of the Mortgage
Loans, the rate and timing of Mortgagor prepayments thereon by the Mortgagors,
liquidations of defaulted Mortgage Loans and purchases of Mortgage Loans due to
certain breaches of 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 certain 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 herein and in the Prospectus under "Yield Considerations"
and "Maturity and Prepayment Considerations"), no assurance can be given as to
such rate or the timing of principal payments on the Offered Certificates.
 
     The Mortgage Loans generally may be prepaid in full or in part at any time.
Although a small portion of the Mortgage Loans provide for payment of a
prepayment charge, it is expected that such loans will not have a substantial
effect on the overall rate of prepayment of the Mortgage Loans. The Mortgage
Loans generally 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" herein, during certain
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 during certain 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
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 in
respect of principal prepayments on such 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 certain 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 Loan-to-Value
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
 
                                      S-44
<PAGE>
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 strip certificates and the
adjustable rate certificates) are fixed, such 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
certain Mortgagor delinquencies, to the extent not covered by Advances. Such
delinquencies may affect the yields to investors on such classes of the Class M
Certificates, and, even if subsequently cured, may affect the timing of the
receipt of distributions by the holders of such 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 such class of
Certificates. Such shortfalls will not be offset by a reduction in the Servicing
Fees payable to the Master Servicer or otherwise, except as described herein
with respect to certain Prepayment Interest Shortfalls. See "Yield
Considerations" in the Prospectus and "Description of the Certificates--Interest
Distributions" herein for a discussion of the effect of principal prepayments on
the Mortgage Loans on the yield to maturity of the Offered Certificates and
certain 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 such shortfalls exceed the amount offset by
the Master Servicer. See "Description of the Certificates--Interest
Distributions" herein.
 
     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 that 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 anticipated at the time of purchase, the
investor's actual yield to maturity will be lower than assumed 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 subject to
various priorities for payment of principal as described herein.
 
                                      S-45
<PAGE>
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 such classes.
 
     Retail Certificates:  IN ADDITION TO THE CONSIDERATIONS SET FORTH ABOVE,
INVESTORS IN THE RETAIL CERTIFICATES SHOULD BE AWARE THAT SUCH CERTIFICATES MAY
NOT BE AN APPROPRIATE INVESTMENT FOR ALL PROSPECTIVE INVESTORS. The Retail
Certificates would not be an appropriate investment for any investor requiring a
distribution of a particular amount of principal or interest on a specific date
or dates or an otherwise predictable stream of cash payments. The timing of such
distributions may have a significant effect on an investor's yield on such
Certificates if the Certificate is purchased at a discount or a premium.
 
     Furthermore, investors in the Retail Certificates should be aware that
because such Certificates have a later priority of payment with respect to
principal in relation to the other classes of Senior Certificates, the effect on
the market value of the Retail Certificates of changes in market interest rates
or market yields for similar securities will be greater than would be the effect
of such changes on other classes of Senior Certificates entitled to earlier
priorities of principal distributions. Furthermore, this later payment priority
also makes the Retail Certificates particularly sensitive to the rate and timing
of principal prepayments on the Mortgage Loans. If prepayments on the Mortgage
Loans occur at a higher rate than anticipated, the weighted average life of the
Retail Certificates may be shortened. Conversely, if prepayments on the Mortgage
Loans occur at a lower rate than anticipated, the weighted average life of the
Retail Certificates may be extended.
 
     PAC Certificates:  The PAC Certificates have been structured so that
principal distributions generally will be made thereon in the amounts determined
by using the table described herein, assuming that prepayments on the Mortgage
Loans occur each month at a constant level within a range which is between
approximately 100% PSA and approximately 400% PSA (the "PAC TARGETED RANGE"),
and based on certain other assumptions.
 
     There can be no assurance that funds available for distribution of
principal on the PAC Certificates will result in the Certificate Principal
Balances equaling their respective Planned Principal Balances for any
Distribution Date. To the extent that prepayments occur at a level below the PAC
Targeted Range, the funds available for principal distributions on the PAC
Certificates on each Distribution Date may be insufficient to reduce the
Certificate Principal Balances of the PAC Certificates to their respective
Planned Principal Balances for such Distribution Date, and the weighted average
lives of the PAC Certificates may be extended. Conversely, to the extent that
prepayments occur at a level above the PAC Targeted Range, after the Certificate
Principal Balances of the Companion Certificates have been reduced to zero, the
Certificate Principal Balances of the PAC Certificates may be reduced below the
Planned Principal Balances and the weighted average lives of the PAC
Certificates may be reduced. In addition, the averaging of high and low
Mortgagor prepayment rates, even if the average prepayment level is within the
PAC Targeted Range, will not ensure the distribution on the PAC Certificates of
an amount that will result in the Certificate Principal Balances equaling their
respective Planned Principal Balances on any Distribution Date because the
balance of the Senior Principal Distribution Amount remaining after
distributions on the PAC Certificates will be distributed on each Distribution
Date and therefore will not be available for distributions on the PAC
Certificates.
 
     It is very unlikely that the Mortgage Loans will prepay at any particular
constant rate. Furthermore, the Planned Principal Balances set forth in the
table under "Description of the Certificates--Principal Distributions on the
Senior Certificates" were calculated based on certain assumptions which may
differ from the actual performance of the Mortgage Loans. The actual prepayment
rates that will result in the Certificate Principal Balances of the PAC
Certificates equaling the amounts set forth in such table may differ from the
rates used to calculate such amounts. The prepayment rates that will result in
the Certificate Principal Balances of the PAC Certificates equaling such amounts
may vary over time as a result of the actual prepayment experience of the
Mortgage Loans. Moreover, because the Planned Principal Balances were calculated
using certain assumptions regarding the Mortgage Loans, the actual prepayment
behavior of the individual Mortgage Loans could be such that the amount
available for distributions of principal in reduction of the PAC Certificates
may not result in their
 
                                      S-46
<PAGE>
respective Certificate Principal Balances or amounts equaling their respective
Planned Principal Balances even if prepayments were to occur at a constant speed
within the PAC Targeted Range.
 
     Companion Certificates:  Investors in the PAC Certificates should be aware
that the stabilization provided by the Companion Certificates is sensitive to
the rate of Mortgagor prepayments on the Mortgage Loans, and that the
Certificate Principal Balances of such Companion Certificates may be reduced to
zero significantly earlier than anticipated. The aggregate initial Certificate
Principal Balance of the Companion Certificates is approximately 113.6% of the
aggregate initial Certificate Principal Balance of the PAC Certificates.
 
     The Companion Certificates will receive monthly principal distributions
from amounts included in the Senior Principal Distribution Amount only after
amounts sufficient to reduce the Certificate Principal Balances of the PAC
Certificates to their respective Planned Principal Balances for any Distribution
Date. Due to the companion nature of the Companion Certificates, such
Certificates will likely experience price and yield volatility. Investors should
consider whether such volatility is suitable to their investment needs.
 
     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 April 2004 and
until the Distribution Date occurring in April 2008 may receive a
disproportionately small portion of principal payments (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 such Certificates will be longer than would otherwise
be the case, and the effect on the market value of such 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 such 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 thereof) because the entire amount of losses that are covered by
Subordination will be allocated to such class of Class M Certificates. See
"--Class M-2 and Class M-3 Certificate Yield Considerations" below. Furthermore,
because principal distributions are paid to certain 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 March 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 such 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 ("PSA"), 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 such
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 "275% PSA" assumes
prepayment rates equal to 100% of PSA and 275% of PSA, respectively, and so
forth. PSA does not purport to be a historical description of
 
                                      S-47
<PAGE>
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" set forth below has been
prepared on the basis of certain assumptions as described below 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"
herein and the performance thereof. The table assumes, among other things, that:
(i) as of the date of the initial 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, such that the
Mortgage Loan will amortize in amounts sufficient for repayment thereof 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 April 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 March 30, 1999 ((i) through (ix) collectively, the "STRUCTURING
ASSUMPTIONS").
 
     The actual characteristics and performance of the Mortgage Loans will
differ from the assumptions used in constructing the table set forth 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 such 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.
 
     Subject to 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 such class
of Offered Certificates that would be outstanding after each of the Distribution
Dates at the various percentages of PSA shown.

*  Indicates a number that is greater than zero but less than 0.5%.
 
** The weighted average life of a Certificate of any class is determined by
   (i) multiplying the amount of each net distribution of Certificate Principal
   Balance by the number of years from the date of issuance of the Certificate
   to the related Distribution Date, (ii) adding the results, and
   (iii) dividing the sum by the aggregate of the net distributions described in
   (i) above.

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 subject to limitation
despite changes in LIBOR in certain 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 such
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 constant 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 constant 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 such 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 such 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 set forth 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 the actual
characteristics and performance thereof), and assuming further that (i) on each
LIBOR Rate Adjustment Date, LIBOR will be at the level shown, (ii) the aggregate
purchase prices of the Class A-3, Class A-4, Class A-14 and Class A-15
Certificates, are $49,999,625, $9,807,619, $23,323,529 and $6,100,000,
respectively, in each case, plus accrued interest, and (iii) the initial
Pass-Through Rates on the Class A-3, Class A-4, Class A-14 and Class A-15
Certificates are set forth in the table on page S-4. 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 herein, 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 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 Adjustable Rate Certificates,
would cause the discounted present value of such assumed stream of cash flows to
equal the assumed purchase price for such 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 herein. 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 such 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.
 
     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 Non-Discount 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 Non-Discount Mortgage Loans could result in the failure of such investors to
fully recover their investments. 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 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 the actual characteristics and performance thereof and
assuming the aggregate purchase prices, including accrued interest, if any, set
forth below. Any differences between such 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 such 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.

     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 such
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 set forth
in the preceding tables 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 generally
likely to prepay under most circumstances at a lower rate than the Non-Discount
Mortgage Loans. In addition, holders of the Variable Strip Certificates
generally 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 generally have higher Mortgage
Rates, such Mortgage Loans are generally 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 herein.
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 such investors
to fully recover their investments.

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
thereof) that are covered by Subordination, because the entire amount of such
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 0.75% 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 thereof) that are covered by
Subordination, because the entire amount of such 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 ("SDA"), 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 such 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.
 
     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 performance of the Mortgage Loans, which differ from the
actual characteristics and performance thereof, and assuming further that (i)
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, (ii) 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, (iii) 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, (iv) there are no Excess
Special Hazard Losses, Excess Fraud Losses, Excess Bankruptcy Losses or
Extraordinary Losses, (v) the assumptions made in clauses (a)(i), (b)(i) and
(b)(ii) in the definition of the Senior Accelerated Distribution Percentage are
not applicable and (vi) the purchase prices of the Class M-2 Certificates and
Class M-3 Certificates will be approximately $9,028,759 and $4,488,602,
respectively, plus 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 such prepayments,
even if losses occur. Any differences between such assumptions and the actual
characteristics and performance of the Mortgage Loans and of the Certificates
may result in yields different from those shown in such tables. Discrepancies
between assumed and actual

     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 Class M-2 Certificates or Class
M-3 Certificates, as applicable, would cause the discounted present value of
such assumed stream of cash flows to equal the assumed purchase price referred
to above, and converting such rate to a corporate bond equivalent yield. 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 Class M-2 Certificates or Class M-3

     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
herein. 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 such 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 such holders in
connection with the purchase of the Residual Certificates on after-tax rates of
return on the Residual Certificates. See "Certain Federal Income Tax
Consequences" herein and in the Prospectus.

Prospectus for important information in addition to that set forth 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. Pursuant to the Pooling and
Servicing Agreement, transfers of Residual Certificates are prohibited to any
non-United States person. Transfers of certain of the Certificates, including
the Residual Certificates, are also subject to additional transfer restrictions
as set forth in the Pooling and Servicing Agreement. See "Certain Federal Income
Tax Consequences" herein and "Certain 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 certain 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 pursuant to the Pooling and Servicing Agreement. For a general
description of Residential Funding and its activities, see "Residential Funding
Corporation" in the Prospectus.

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 on December 31, 1996,
December 31, 1997 and December 31, 1998. 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 herein, 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 herein 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 certain information concerning foreclosed
mortgage loans and loan loss experience of Residential Funding as of
December 31, 1996, December 31, 1997 and December 31, 1998, 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
such period.

</TABLE>
 
- ------------------
(1) The tables relate only to the mortgage loans referred to above.
 
(2) 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.
 
(3) Liquidated Foreclosed Loans is the sum of the principal balances of the
    foreclosed loans liquidated during the period indicated.
 
(4) Gross Loss is the sum of 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 such
    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 in footnote (5) below. Net gains from the
    liquidation of mortgage loans are identified in footnote (7) below.
 
(5) 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.
 
(6) Net Loss is determined by subtracting Covered Loss from Gross Loss. As is
    the case in footnote (4) above, Net Loss indicated here may reflect Excess
    Recovery (see footnote (7) below). Net Loss includes losses on mortgage loan
    pools which do not have the benefit of credit enhancement.
 
(7) 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 such Mortgage Loan. Excess
    recoveries are not applied to reinstate any credit enhancement, and
    generally are not allocated to holders of Certificates.
 
SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES
 
     The Servicing Fees for each Mortgage Loan are payable out of the interest
payments on such Mortgage Loan. The Servicing Fees in respect of each Mortgage
Loan will be at least 0.28% per annum and not more than 0.58% per annum of the
outstanding principal balance of such Mortgage Loan, with a weighted average
Servicing Fee of approximately 0.3247% 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 prepayment 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 in respect of its
 
                                      S-63
<PAGE>
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 0.0747%. 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 certain 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
 
     Certain actions specified in the Prospectus that may be taken by holders of
Certificates evidencing a specified percentage of all undivided interests in the
Trust may be taken by holders of Certificates entitled in the aggregate to such
percentage of the Voting Rights. 98% of all Voting Rights will be allocated
among all holders of the Certificates (other than the Variable Strip
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,
respectively, in proportion to the Percentage Interests (as defined in the
Prospectus) evidenced by their respective Certificates. The Pooling and
Servicing Agreement will be subject to amendment without the consent of the
holders of the Residual Certificates in certain circumstances.
 
TERMINATION
 
     The circumstances under which the obligations created by the Pooling and
Servicing Agreement will terminate in respect of 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 (i) to purchase all
remaining Mortgage Loans and other assets in the Trust, thereby effecting early
retirement of the Offered Certificates or (ii) 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 such repurchase price is distributed.
Distributions on the Certificates in respect of any such 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 such 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 the Certificate Principal Balance thereof plus (except
with respect to the Principal Only Certificates) the sum of interest thereon (or
with respect to the Variable Strip Certificates, on the Notional Amount thereof)
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 above, the holders of the Offered Certificates will
receive an amount equal to the Certificate Principal Balance of such 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
the Notional Amount thereof), plus any previously unpaid Accrued Certificate
Interest (reduced, as described above, in the case of the termination of the
Trust resulting from a purchase of all the assets of the Trust).

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Upon the issuance of the Offered Certificates, Thacher Proffitt & Wood,
counsel to the Depositor, will deliver its opinion generally 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
Code.
 
     For federal income tax purposes, 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 and the Class R
Certificates will constitute the sole class of "residual certificates" in the
REMIC. See "Certain Federal Income Tax Consequences--REMICs" in the Prospectus.
 
     For federal income tax reporting purposes, the Class A-4, Class A-8, Class
A-13, Class A-15, Class A-P, Class A-V, Class M-2, and Class M-3 Certificates
will, Class A-9 Certificates may and all other classes of Offered Certificates
will not, 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 275% PSA. No
representation is made that the Mortgage Loans will prepay at that rate or at
any other rate. See "Certain Federal Income Tax Consequences--General" and
"--REMICs--Taxation of Owners of REMIC Regular Certificates--Original Issue
Discount" in the Prospectus.
 
     Purchasers of the Offered Certificates should be aware that Section
1272(a)(6) of the Code and the OID Regulations do not adequately address certain
issues relevant to, or applicable to, prepayable securities such as the Offered
Certificates. In addition, there is considerable uncertainty concerning the
application of the OID Regulations to Certificates such as the Adjustable Rate
Certificates that provide for payments based on an adjustable rate. In the
absence of other authority, the Master Servicer intends to be guided by certain
principles of the OID Regulations applicable to variable rate debt instruments
in adapting the provisions of Section 1272(a)(6) of the Code to such
Certificates for the purpose of preparing reports furnished to
Certificateholders and the IRS. Because of the uncertainties concerning the
application of Section 1272(a)(6) of the Code to the Offered Certificates and
because the rules relating to debt instruments having an adjustable rate of
interest are limited in their application in ways that could preclude their
application to such Certificates even in the absence of Section 1272(a)(6) of
the Code, the IRS could assert that the Adjustable Rate Certificates should be
treated as issued with interest other than "qualified stated interest" (within
the meaning of the OID Regulations) or that such Offered Certificates should be
governed by some other method not yet set forth in regulations. Prospective
purchasers of the Offered Certificates are advised to consult their tax advisors
concerning the tax treatment of the Offered Certificates.
 
     The Internal Revenue Service (the "IRS") has issued regulations (the "OID
REGULATIONS") under sections 1271 to 1275 of the Code generally addressing the
treatment of debt instruments issued with original issue discount. The OID
Regulations suggest that original issue discount with respect to securities such
as 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 such uncertificated regular interests as a single debt
instrument as set forth 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 such
period would be zero and such Certificateholder will be permitted to offset such
negative amount only against future original issue discount (if any)
attributable to such Certificates.
 
     In certain 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.

     Certain classes of the Offered Certificates may be treated for federal
income tax purposes as having been issued at a premium. Whether any holder of
such a class of Certificates will be treated as holding a certificate with
amortizable bond premium will depend on such Certificateholder's purchase price
and the distributions remaining to be made on such Certificate at the time of
its acquisition by such Certificateholder. Holders of such classes of
Certificates should consult their tax advisors regarding the possibility of
making an election to amortize such premium. See "Certain 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 Code and "real estate assets" under Section 856(c)(4)(A)
of the 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 Code generally to the extent that such Offered Certificates
are treated as "real estate assets" under Section 856(c)(4)(A) of the Code.
Moreover, the Offered Certificates (other than the Residual Certificates) will
be "qualified mortgages" within the meaning of Section 860G(a)(3) of the 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 Code should note that, notwithstanding such treatment, any
repurchase of such a Certificate pursuant to the right of the Master Servicer or
the Depositor to repurchase such Offered Certificates may adversely affect any
REMIC that holds such Offered Certificates if such repurchase is made under
circumstances giving rise to a Prohibited Transaction Tax. See "The Pooling and
Servicing Agreement--Termination" herein and "Certain 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 "Certain 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 Code that
significantly affect holders of Residual Certificates. The REMIC Regulations
impose restrictions on the transfer or acquisition of certain residual
interests, including the Residual Certificates. The Pooling and Servicing
Agreement includes certain other provisions regarding the transfer of Residual
Certificates, including (i) the requirement that any transferee of a Residual
Certificate provide an affidavit representing that such transferee (a) is not a
"disqualified organization," (b) is not acquiring the Residual Certificate on
behalf of a "disqualified organization" and (c) will maintain such status and
will obtain a similar affidavit from any person to whom such transferee shall
subsequently transfer a Residual Certificate, (ii) a provision that any transfer
of a Residual Certificate to a "disqualified person" shall be null and void and
(iii) 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
(i) and (ii) above. In addition, pursuant to 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 such 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 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 with respect to the income on the Residual Certificates. All
transfers of the Residual Certificates will be subject to certain restrictions
under the terms of the Pooling and Servicing Agreement that are intended to
reduce the possibility of any such transfer being disregarded to the extent that
the Residual Certificates constitute noneconomic residual interests. See
"Certain Federal Income Tax Consequences--REMICs--Taxation of Owners of REMIC
Residual Certificates--Noneconomic REMIC Residual Certificates" in the
Prospectus.
 
                                      S-66
<PAGE>
     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
such Residual Certificateholders from the REMIC with respect to such periods.
Furthermore, the tax on such income may exceed the cash distributions with
respect to such 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 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 such Residual Certificates over their life.
 
     An individual, trust or estate that holds (whether directly or indirectly
through certain pass-through entities) a Residual Certificate, may have
significant additional gross income with respect to, but may be subject to
limitations on the deductibility of, servicing and trustee's fees and other
administrative expenses properly allocable to the REMIC in computing such
Certificateholder's regular tax liability and will not be able to deduct such
fees or expenses to any extent in computing such Certificateholder's alternative
minimum tax liability. See "Certain 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 such
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" herein and "Certain Federal Income Tax
Consequences--REMICs--Taxation of Owners of REMIC Residual Certificates" in the
Prospectus.
 
                             METHOD OF DISTRIBUTION
 
     Subject to the terms and conditions set forth in an Underwriting Agreement,
dated March 25, 1999 (the "UNDERWRITING AGREEMENT"), Salomon Smith Barney Inc.
(the "UNDERWRITER") 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 and a de minimis portion of the Residual Certificates, and the
Class M Certificates (the "UNDERWRITTEN CERTIFICATES"). A de minimis portion of
the Residual Certificates will be retained by Residential Funding, and such
portion is not offered hereby. It is expected that delivery of the 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 the
Underwriter, New York, New York, on or about March 30, 1999 against payment
therefor in immediately available funds.
 
     In connection with the Underwritten Certificates, the Underwriter has
agreed, subject to the terms and conditions set forth in the Underwriting
Agreement, to purchase all of the Underwritten Certificates if any of the
Underwritten Certificates are purchased thereby.
 
     The Underwriting Agreement provides that the obligations of the Underwriter
to pay for and accept delivery of the Underwritten Certificates are subject to,
among other things, the receipt of certain 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 such
purpose shall be pending before or threatened by the Securities and Exchange
Commission.
 
                                      S-67
<PAGE>
     The distribution of the Underwritten Certificates by the Underwriter 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 Underwritten Certificates, before deducting
expenses payable by the Depositor, will be approximately 99.27% of the aggregate
Certificate Principal Balance of the Underwritten Certificates plus accrued
interest thereon from the Cut-off Date. The Underwriter may effect such
transactions by selling the Underwritten Certificates to or through dealers, and
such dealers may receive compensation in the form of underwriting discounts,
concessions or commissions from the Underwriter for whom they act as agent. In
connection with the sale of the Underwritten Certificates, the Underwriter may
be deemed to have received compensation from the Depositor in the form of
underwriting compensation. The Underwriter and any dealers that participate with
the Underwriter in the distribution of the 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 of 1933, as amended.
 
     The Underwriting Agreement provides that the Depositor will indemnify the
Underwriter, and that under limited circumstances the Underwriter will indemnify
the Depositor, against certain liabilities under the Securities Act of 1933, as
amended, 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. Proceeds to the Depositor from any sale of the
Class A-P Certificates or Class A-V Certificates will equal the purchase price
paid by the purchaser thereof, net of any expenses payable by the Depositor and
any compensation payable to any such underwriter or agent.
 
     There is currently no secondary market for the Offered Certificates. The
Underwriter intends to make a secondary market in the Underwritten Certificates
but is not obligated to do so. There can be no 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 generally available on an
ongoing basis. The limited nature of such 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 by Thacher Proffitt & Wood, New York, New York and for the
Underwriter 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 Ratings Services, a division of The
McGraw-Hill Companies, Inc. ("STANDARD & POOR'S") and Fitch IBCA, Inc. ("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
 
                                      S-68
<PAGE>
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" herein. 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: securities whose principal or interest return
is indexed to equities, commodities, or currencies; certain swaps and options;
and 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 set forth 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 the Certificate Principal Balance
thereof. The rating on the Residual Certificates only addresses the return of
the Certificate Principal Balance thereof and interest thereon at the related
Pass-Through Rate.
 
     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 such 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 such 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 certain 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. Certain
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.
 
     The Office of Thrift Supervision (the "OTS") has issued Thrift Bulletin
13a, entitled "Management of Interest Rate Risk, Investment Securities, and
Derivatives Activities" ("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 (i) conduct a pre-purchase portfolio sensitivity
analysis for any "significant transaction" involving securities or financial
derivatives, and (ii) conduct 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 the Offered Certificates 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
 
                                      S-69
<PAGE>
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.
 
     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 Plan, any insurance company (whether through its general
or separate accounts) or any other person investing "PLAN ASSETS" of any 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 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 Plan Assets
of, a 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 any such 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 of 1933, as
amended.
 
     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 hereof.
 
     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 Plan, any trustee or other person acting
on behalf of any Plan, or any other person using Plan Assets to effect such
acquisition or holding (each, a "PLAN INVESTOR") unless (i) such acquirer or
holder is an insurance company, (ii) the source of funds used to acquire or hold
such Certificate (or interest therein) is an "insurance company general account"
(as defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth 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 such 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 such Certificate (or interest therein)
is an "insurance company general account" (as such term is defined in PTCE
95-60), and (3) the conditions set forth 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 such 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
 
                                      S-70
<PAGE>
Trustee, the Master Servicer, any Subservicer, and the Trust from and against
any and all liabilities, claims, costs or expenses incurred by such parties as a
result of such acquisition or holding.
 
     Investors in the Class M Certificates are urged to obtain from a transferee
of such Certificates a certification of such transferee's eligibility to
purchase such Certificates in the form of the representation letter attached as
Annex I hereto.
 
     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 such 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 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 such Certificates by or on behalf of such
Plan Investor is permissible under applicable law, will not constitute or result
in a non-exempt prohibited transaction under ERISA or Section 4975 of the 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.
 
     Any fiduciary or other investor of Plan Assets that proposes to acquire or
hold the Offered Certificates on behalf of or with Plan Assets of any 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 Code to the proposed investment. See "ERISA Considerations"
in the Prospectus.
 
     The sale of any of the Offered Certificates to a Plan is in no respect a
representation by the Depositor or the related Underwriter that such an
investment meets all relevant legal requirements with respect to investments by
Plans generally or any particular Plan, or that such an investment is
appropriate for Plans generally or any particular Plan.

Mortgage Pass-Through Certificates

Residential Funding Mortgage Securities I, Inc.

Depositor

The Mortgage Pass-Through  Certificates (the "Certificates")  offered hereby may
be sold from time to time in series,  as  described  in the  related  Prospectus
Supplement.  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  "Company") or any other
entity  specified  in  the  related  Prospectus  Supplement,  in  a  trust  fund
consisting  primarily of a segregated pool of conventional  one- to four-family,
residential  first mortgage loans (the  "Mortgage  Loans") or interests  therein
(which may include  Mortgage  Securities,  as defined  herein),  acquired by the
Company  from one or more  affiliated  or  unaffiliated  institutions.  See "The
Mortgage  Pools."  See "Index of  Principal  Definitions"  for the  meanings  of
capitalized terms and acronyms.

The Mortgage Loans and certain other assets described herein under "The Mortgage
Pools"  and  in  the  related  Prospectus  Supplement  will  be  held  in  trust
(collectively,  a "Trust  Fund") for the  benefit of the  holders of the related
series of Certificates and the Excess Spread,  if any, pursuant to a Pooling and
Servicing  Agreement  as  described  herein  under "The  Mortgage  Pools."  Each
Mortgage Pool will consist of one or more types of the various types of Mortgage
Loans described under "The Mortgage Pools." Information  regarding each class of
Certificates of a series, and the general  characteristics of the Mortgage Loans
to be  evidenced  by  such  Certificates,  will  be set  forth  in  the  related
Prospectus Supplement.

Each series of  Certificates  will  include one or more  classes.  Each class of
Certificates  of any series will represent the right,  which right may be senior
or  subordinate  to the  rights  of one or  more  of the  other  classes  of the
Certificates,  to  receive a  specified  portion of  payments  of  principal  or
interest (or both) on the Mortgage Loans in the related Trust Fund in the manner
described herein and in the related Prospectus  Supplement.  See "Description of
the  Certificates--Distributions."  A series may include one or more  classes of
Certificates entitled to principal distributions, with disproportionate, nominal
or   no   interest   distributions,   or   to   interest   distributions,   with
disproportionate,  nominal or no principal  distributions.  A series may include
two or more classes of  Certificates  which differ as to the timing,  sequential
order,  priority of payment,  pass-through  rate or amount of  distributions  of
principal or interest or both.

The Company's only obligations with respect to a series of Certificates  will be
pursuant to certain limited  representations  and warranties made by the Company
or as  otherwise  described  in the related  Prospectus  Supplement.  The master
servicer  (the  "Master  Servicer")  for each  series  of  Certificates  will be
identified in the related Prospectus  Supplement.  The principal  obligations of
the Master Servicer will be its contractual servicing obligations (which include
its limited obligation to make certain advances in the event of delinquencies in
payments on the Mortgage Loans). See "Description of the Certificates."

If so  specified  in the  related  Prospectus  Supplement,  the Trust Fund for a
series of Certificates may include any one or any combination of a mortgage pool
insurance policy,  letter of credit,  bankruptcy bond,  special hazard insurance
policy, reserve fund, certificate insurance policy, surety bond or other form of
credit support.  In addition to or in lieu of the foregoing,  credit enhancement
may  be  provided  by  means  of  subordination.   See  "Description  of  Credit
Enhancement."

The rate of payment of  principal  of each class of  Certificates  entitled to a
portion of principal  payments on the Mortgage Loans will depend on the priority
of  payment  of such  class  and the  rate  and  timing  of  principal  payments
(including prepayments,  defaults, liquidations and repurchases) on the Mortgage
Loans and other assets in the Trust Fund. A rate of principal  payment  lower or
higher than that  anticipated may affect the yield on each class of Certificates
in the manner described  herein and in the related  Prospectus  Supplement.  See
"Yield Considerations."

For  a  discussion  of  significant   matters   affecting   investments  in  the
Certificates, see "Risk Factors," commencing herein on page[10].

One or more  separate  elections  may be made to  treat a Trust  Fund as a "real
estate mortgage investment conduit" (a "REMIC") for federal income tax purposes.
The Prospectus  Supplement for a series of Certificates will specify which class
or  classes of the  related  series of  Certificates  will be  considered  to be
regular  interests in the related REMIC and which class of Certificates or other
interests will be designated as the residual  interest in the related REMIC,  if
applicable. See "Certain Federal Income Tax Consequences."

PROCEEDS  OF THE ASSETS IN THE TRUST FUND ARE THE SOLE SOURCE OF PAYMENTS ON THE
CERTIFICATES.  THE CERTIFICATES DO NOT REPRESENT AN INTEREST IN OR OBLIGATION OF
THE COMPANY, THE MASTER SERVICER, GMAC MORTGAGE GROUP, INC. ("GMAC MORTGAGE") OR
ANY OF THEIR  AFFILIATES.  NEITHER THE CERTIFICATES NOR THE UNDERLYING  MORTGAGE
LOANS OR MORTGAGE  SECURITIES WILL BE GUARANTEED OR INSURED BY ANY  GOVERNMENTAL
AGENCY OR INSTRUMENTALITY OR BY THE COMPANY, THE MASTER SERVICER,  GMAC MORTGAGE
OR ANY OF THEIR AFFILIATES.

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE  COMMISSION OR ANY STATE  SECURITIES  COMMISSION NOR HAS THE SECURITIES
AND  EXCHANGE  COMMISSION  OR ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

Offers of the  Certificates  may be made through one or more different  methods,
including  offerings  through  underwriters,  as  described  under  "Methods  of
Distribution"  and  in the  related  Prospectus  Supplement.  There  will  be no
secondary market for any series of Certificates  prior to the offering  thereof.
There can be no assurance  that a secondary  market for any of the  Certificates
will develop or, if it does develop,  that it will  continue.  The  Certificates
will not be listed on any securities exchange.

Retain this Prospectus for future reference.  This Prospectus may not be used to
consummate sales of securities offered hereby unless accompanied by a Prospectus
Supplement.
                              ---------------------

                              SUMMARY OF PROSPECTUS

         The following  summary is qualified in its entirety by reference to the
detailed information  appearing elsewhere in this Prospectus and by reference to
the  information  with respect to each series of  Certificates  contained in the
Prospectus  Supplement  to be prepared  and  delivered  in  connection  with the
offering of such  series.  Capitalized  terms used in this  summary that are not
otherwise  defined shall have the meanings  ascribed thereto in this Prospectus.
An index  indicating  where certain terms used herein are defined appears at the
end of this Prospectus.

Securities Offered..............    Mortgage Pass-Through Certificates.

Company.........................    Residential Funding Mortgage Securities I,
                                    Inc. See "The Company."

Master Servicer.................    The entity identified as Master Servicer in
     the  related  Prospectus  Supplement,  which  may  be  Residential  Funding
     Corporation,  an  affiliate  of the Company  ("Residential  Funding").  See
     "Residential   Funding   Corporation"   and  "The  Pooling  and   Servicing
     Agreement--Certain Matters Regarding the Master Servicer and the Company."

Trustee.........................    The trustee (the "Trustee") for each series
     of Certificates will be specified in the related Prospectus Supplement.

Certificates....................    Each series of Certificates will represent
     in the aggregate the entire beneficial  ownership  interest,  excluding any
     interest  retained  by the  Company or any other  entity  specified  in the
     related Prospectus  Supplement,  in a pool (the "Mortgage Pool") of certain
     Mortgage Loans or interests therein (which may include Mortgage  Securities
     as defined  herein),  and certain  other  assets as described  below.  Each
     series of  Certificates  will be issued pursuant to a pooling and servicing
     agreement  among the Company,  the Trustee and the Master Servicer (each, a
     "Pooling and Servicing Agreement").  As specified in the related Prospectus
     Supplement,  each series of  Certificates,  or class of Certificates in the
     case of a  series  consisting  of two or more  classes,  may  have a stated
     principal balance, no stated principal balance or a notional amount and may
     be entitled to distributions of interest based on a specified interest rate
     or  rates  (each,  a  "Pass-  Through  Rate").  Each  series  or  class  of
     Certificates may have a different Pass- Through Rate, which may be a fixed,
     variable or adjustable Pass-Through Rate, or any combination of two or more
     of such Pass-Through Rates. The related Prospectus  Supplement will specify
     the Pass-Through Rate or Rates for each series or class of Certificates, or
     the  initial  Pass-Through  Rate or Rates and the  method  for  determining
     subsequent changes to the Pass-Through Rate or Rates.

     A series may include one or more classes of  Certificates  (each,  a "Strip
     Certificate")    entitled   to   (i)    principal    distributions,    with
     disproportionate,  nominal or no interest  distributions,  or (ii) interest
     distributions,    with   disproportionate,    nominal   or   no   principal
     distributions.  In addition,  a series may include  classes of Certificates
     which  differ  as  to  timing,   sequential  order,  priority  of  payment,
     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,  or on the basis of collections from designated
     portions of the Mortgage  Pool.  In  addition,  a series may include one or
     more classes of Certificates ("Accrual Certificates"),  as to which certain
     accrued  interest will not be  distributed  but rather will be added to the
     principal balance thereof in the manner described in the related Prospectus
     Supplement. One or more classes of Certificates in a series may be entitled
     to receive principal  payments  pursuant to an amortization  schedule under
     the circumstances described in the related Prospectus Supplement.

     If  so  specified  in  the  related  Prospectus  Supplement,  a  series  of
     Certificates may include one or more classes of Certificates (collectively,
     the  "Senior  Certificates")  which are  senior to one or more  classes  of
     Certificates  (collectively,  the "Subordinate Certificates") in respect of
     certain  distributions  of principal and interest and allocations of losses
     on the Mortgage Loans. See  "Subordination." If so specified in the related
     Prospectus  Supplement,  a series of  Certificates  may include one or more
     classes of Certificates (collectively,  the "Mezzanine Certificates") which
     are Subordinate  Certificates but which are senior to certain other classes
     of Subordinate  Certificates in respect of such distributions or losses. In
     addition,  certain  classes of Senior  Certificates  may be senior to other
     classes of Senior  Certificates in respect of such distributions or losses.
     The Certificates will be issued in fully-registered certificated or book-

     entry  form  in the  authorized  denominations  specified  in  the  related
     Prospectus Supplement. See "Description of the Certificates."

     Neither the  Certificates  nor the  underlying  Mortgage  Loans or Mortgage
     Securities  will be  guaranteed  or insured by any  governmental  agency or
     instrumentality  or by the Company,  the Master Servicer,  GMAC Mortgage or
     any of their affiliates.

Mortgage Pools..................    Unless otherwise specified in the related
     Prospectus  Supplement,  each Trust Fund will consist primarily of Mortgage
     Loans or interests  therein  secured by first liens on one- to  four-family
     residential  properties,  located in any one of the 50 states, the District
     of  Columbia   or  the   Commonwealth   of  Puerto  Rico  (the   "Mortgaged
     Properties").  All Mortgage  Loans will have been purchased by the Company,
     either  directly  or  through  Residential  Funding,   from  mortgage  loan
     originators  or  sellers  who,  as  specified  in  the  related  Prospectus
     Supplement,  may or may not be affiliated  with the Company  including GMAC
     Mortgage  Corporation  and  HomeComings   Financial  Network,   Inc.,  each
     affiliates of the Company.  Mortgage Loans secured by Mortgaged  Properties
     located in Puerto Rico are  sometimes  referred  to herein as "Puerto  Rico
     Mortgage  Loans." See "Mortgage  Loan  Program."  For a description  of the
     types of Mortgage  Loans that may be included in the  Mortgage  Pools,  see
     "The Mortgage Pools--The Mortgage Loans."

     If specified in the related Prospectus Supplement, Mortgage Loans which are
     converting or converted from an  adjustable-rate to a fixed-rate or certain
     Mortgage  Loans  for  which  the  Mortgage  Rate  has  been  reset  may  be
     repurchased  by the Company or  purchased  by the  applicable  Subservicer,
     Residential  Funding or another party,  or a designated  remarketing  agent
     will use its best efforts to arrange the sale thereof as described herein.

     If specified in the related Prospectus Supplement, a Trust Fund may include
     mortgage pass-through  certificates  evidencing interests in Mortgage Loans
     ("Mortgage   Securities"),   as  described   herein.   See  "The   Mortgage
     Pools--General" herein.

Interest Distributions..........  Except as otherwise specified herein or in the
     related  Prospectus  Supplement,  interest on each class of Certificates of
     each series,  other than Strip Certificates or Accrual  Certificates (prior
     to the  time  when  accrued  interest  becomes  payable  thereon),  will be
     remitted at the applicable  Pass-Through Rate on the outstanding  principal
     balance of such  class,  on the 25th day (or, if such day is not a business
     day,  the next  business  day) of each  month,  commencing  with the  month
     following the month in which the Cut-off Date (as defined in the applicable
     Prospectus  Supplement)  occurs  (each,  a  "Distribution  Date").  If  the
     Prospectus Supplement so specifies,  interest distributions on any class of
     Certificates  may be reduced on account  of  negative  amortization  on the
     Mortgage Loans, with the Deferred Interest (as defined herein) allocable to
     such class added to the principal balance thereof,  which Deferred Interest
     will  thereafter  bear  interest  at  the  applicable   Pass-Through  Rate.
     Distributions,  if any, with respect to interest on Strip Certificates will
     be made on each  Distribution  Date as described  herein and in the related
     Prospectus       Supplement.       See       "Description       of      the
     Certificates--Distributions."  Strip  Certificates  that  are  entitled  to
     distributions  of principal only will not receive  distributions in respect
     of  interest.  Interest  that has  accrued  but is not yet  payable  on any
     Accrual  Certificates  will be added to the principal balance of such class
     on the related  Distribution Date, and will thereafter bear interest at the
     applicable  Pass-Through  Rate.  Unless otherwise  specified in the related
     Prospectus Supplement, distributions of interest with respect to any series
     of Certificates (or accruals thereof in the case of Accrual  Certificates),
     or with respect to one or more classes included therein,  may be reduced to
     the extent of interest shortfalls not covered by advances or the applicable
     form of credit support,  including any Prepayment Interest Shortfalls.  See
     "Description   of  the   Certificates"   and   "Maturity   and   Prepayment
     Considerations."

Principal  Distributions.........  Except as otherwise  specified in the related
     Prospectus Supplement,  principal distributions on the Certificates of each
     series  will be  payable on each  Distribution  Date,  commencing  with the
     Distribution  Date in the month  following  the month in which the  Cut-off
     Date occurs,  to the holders of the Certificates of such series,  or of the
     class or classes of Certificates then entitled thereto, on a pro rata basis
     among all such Certificates or among the Certificates of any such


                                        6

     class, in proportion to their respective outstanding principal balances, or
     the percentage  interests  represented  by such class,  in the priority and
     manner specified in the related Prospectus  Supplement.  Strip Certificates
     with no  principal  balance  will not receive  distributions  in respect of
     principal.  Distributions  of  principal  with  respect  to  any  class  of
     Certificates,  may be reduced to the  extent of certain  delinquencies  not
     covered by advances or losses not covered by the applicable  form of credit
     enhancement.   See  "The  Mortgage   Pools,"   "Maturity   and   Prepayment
     Considerations" and "Description of the Certificates."

Yield and Prepayment
   Considerations...............    The Mortgage Loans supporting a series of
     Certificates will have unique characteristics that will affect the yield to
     maturity  and the rate of payment of principal  on such  Certificates.  See
     "Yield Considerations" and "Maturity and Prepayment  Considerations" herein
     and in the related Prospectus Supplement.

Credit Enhancement..............    If so specified in the related Prospectus
     Supplement,  the Trust Fund with respect to any series of Certificates  may
     include any one or any  combination  of a letter of credit,  mortgage  pool
     insurance policy, special hazard insurance policy, bankruptcy bond, reserve
     fund,  certificate  insurance  policy,  surety bond or other type of credit
     support  to  provide  partial  coverage  for  certain  defaults  and losses
     relating to the Mortgage Loans.  Credit support also may be provided in the
     form of  subordination  of one or more classes of  Certificates in a series
     under  which  certain  losses  are  first   allocated  to  any  Subordinate
     Certificates    up   to   a   specified   limit   or   in   the   form   of
     Overcollateralization.  Any form of credit enhancement  typically will have
     certain limitations and exclusions from coverage thereunder,  which will be
     described in the related Prospectus  Supplement.  Losses not covered by any
     form of credit  enhancement  will be borne by the  holders  of the  related
     Certificates  (or  certain  classes  thereof).  To the extent not set forth
     herein, the amount and types of coverage,  the identification of any entity
     providing  the  coverage,  the  terms  of  any  subordination  and  related
     information  will be set forth in the Prospectus  Supplement  relating to a
     series  of  Certificates.  See  "Description  of  Credit  Enhancement"  and
     "Subordination."

Advances........................    Unless otherwise specified in the related
     Prospectus  Supplement,  the Master Servicer will be obligated (pursuant to
     the  terms of the  related  Mortgage  Securities,  if  applicable)  to make
     certain  advances  with  respect to  delinquent  scheduled  payments on the
     Mortgage Loans,  but only to the extent that the Master  Servicer  believes
     that such amounts will be recoverable by it. Any advance made by the Master
     Servicer with respect to a Mortgage Loan is  recoverable  by it as provided
     herein  under  "Description  of  the  Certificates--Advances"  either  from
     recoveries  on the specific  Mortgage  Loan or, with respect to any advance
     subsequently  determined  to be  nonrecoverable,  out  of  funds  otherwise
     distributable to the holders of the related series of Certificates.

Optional Termination............    The Master Servicer, the Company or, if
     specified in the related Prospectus Supplement,  the holder of the residual
     interest in a REMIC may at its option either (i) effect early retirement of
     a series of Certificates  through the purchase of the assets in the related
     Trust Fund or (ii)  purchase,  in whole but not in part,  the  Certificates
     specified  in the  related  Prospectus  Supplement;  in each case under the
     circumstances  and in the manner set forth  herein  under "The  Pooling and
     Servicing  Agreement--Termination;  Retirement of Certificates"  and in the
     related Prospectus Supplement.

Rating..........................    At the date of issuance, as to each series,
     each class of Certificates  offered hereby will be rated, at the request of
     the Company,  in one of the four highest  rating  categories by one or more
     nationally   recognized   statistical  rating  agencies  (each,  a  "Rating
     Agency"). See "Ratings" in the related Prospectus Supplement.

Legal Investment................    If so specified in the related Prospectus
     Supplement,  certain  classes  of  Certificates  offered  hereby and by the
     related  Prospectus  Supplement  that are  rated in one of the two  highest
     rating  categories by at least one Rating Agency will constitute  "mortgage
     related   securities"  for  purposes  of  the  Secondary   Mortgage  Market
     Enhancement Act of 1984, as amended ("SMMEA"),  for so long as such classes
     sustain such a rating. See "Legal Investment Matters."

ERISA Considerations............    A fiduciary of an employee benefit plan and
     certain  other  plans and  arrangements,  including  individual  retirement
     accounts and annuities, Keogh

     plans,  bank collective  investment  funds,  insurance  company general and
     separate accounts and certain other entities in which such plans, accounts,
     annuities or  arrangements  are invested,  which is subject to the Employee
     Retirement  Income Security Act of 1974, as amended  ("ERISA"),  or Section
     4975 of the  Internal  Revenue  Code of 1986  (the  "Code"),  and any other
     person contemplating  purchasing a Certificate with Plan Assets (as defined
     herein),  should  carefully  review  with its  legal  counsel  whether  the
     purchase or holding of Certificates  could give rise to a transaction  that
     is prohibited or is not otherwise permissible either under ERISA or Section
     4975 of the Code.  See "ERISA  Considerations"  herein  and in the  related
     Prospectus Supplement.

Certain Federal Income
Tax Consequences................    Certificates of each series offered hereby
     will  constitute  "regular  interests"  or "residual  interests" in a Trust
     Fund, or a portion thereof,  treated as a REMIC under Sections 860A through
     860G of the Code,  unless  otherwise  specified  in the related  Prospectus
     Supplement. See "Certain Federal Income Tax Consequences" herein and in the
     related Prospectus Supplement.

                                  RISK FACTORS

         Investors should consider, among other things, the following factors in
connection with the purchase of the Certificates:

         Limited  Liquidity.  There can be no assurance that a secondary  market
for the Certificates of any series will develop or, if it does develop,  that it
will provide  Certificateholders  with  liquidity of  investment or that it will
continue  for  the  life  of the  Certificates  of any  series.  The  Prospectus
Supplement  for any series of  Certificates  may  indicate  that an  underwriter
specified therein intends to establish a secondary market in such  Certificates,
however no underwriter will be obligated to do so. The Certificates  will not be
listed on any securities exchange.

         Limited Obligations. The Certificates will not represent an interest in
or obligation of the Company, the Master Servicer, GMAC Mortgage or any of their
affiliates.  The only obligations of the foregoing  entities with respect to the
Certificates,  the  Mortgage  Loans  or  any  Mortgage  Securities  will  be the
obligations (if any) of the Company and the Master Servicer  pursuant to certain
limited  representations and warranties made with respect to the Mortgage Loans,
the Master  Servicer's  servicing  obligations  under the  related  Pooling  and
Servicing Agreement  (including its limited obligation to make certain Advances)
and pursuant to the terms of any Mortgage Securities,  and, if and to the extent
expressly  described  in the  related  Prospectus  Supplement,  certain  limited
obligations of the Master Servicer in connection with a Swap,  Yield  Supplement
Agreement, Purchase Obligation or an agreement to purchase or act as remarketing
agent with respect to a  Convertible  Mortgage  Loan upon  conversion to a fixed
rate.  If an affiliate of the Company has  originated  any Mortgage  Loan,  such
affiliate will only have an obligation with respect to the  representations  and
warranties of the Seller, as described herein.  Neither the Certificates nor the
underlying  Mortgage Loans or Mortgage  Securities will be guaranteed or insured
by any governmental  agency or  instrumentality,  or by the Company,  the Master
Servicer,  GMAC  Mortgage  or any of their  affiliates.  Proceeds  of the assets
included in the related  Trust Fund  (including  the Mortgage  Loans or Mortgage
Securities  and any  form of  credit  enhancement)  will be the sole  source  of
payments on the Certificates,  and there will be no recourse to the Company, the
Master  Servicer,  GMAC  Mortgage  or any other  entity  in the event  that such
proceeds are insufficient or otherwise unavailable to make all payments provided
for under the Certificates.

         Limitations,  Reduction and  Substitution of Credit  Enhancement.  With
respect to each series of  Certificates,  credit  enhancement may be provided in
limited  amounts to cover  certain  types of losses on the  underlying  Mortgage
Loans.  Credit enhancement will be provided in one or more of the forms referred
to herein,  including,  but not limited to:  subordination  of other  classes of
Certificates of the same series;  a Letter of Credit; a Purchase  Obligation;  a
Mortgage Pool Insurance  Policy; a Special Hazard Insurance Policy; a Bankruptcy
Bond;  a  Reserve  Fund;  a  Certificate   Insurance   Policy;  a  Surety  Bond;
Overcollateralization  or  any  combination  thereof.  See  "Subordination"  and
"Description  of Credit  Enhancement"  herein.  Regardless of the form of credit
enhancement  provided,  the amount of coverage  will be limited in amount and in
most cases will be subject to periodic  reduction in accordance  with a schedule
or formula.  Furthermore,  such credit enhancement may provide only very limited
coverage as to certain types of losses or risks,  and may provide no coverage as
to certain other types of losses or risks. In the event losses exceed the amount
of coverage  provided by any credit  enhancement or losses of a type not covered
by any credit enhancement occur, such losses will be borne by the holders of the
related  Certificates  (or certain  classes  thereof).  The Master Servicer will
generally be permitted to reduce,  terminate or  substitute  all or a portion of
the credit enhancement for any series of Certificates,  if the applicable Rating
Agency, as set forth in the related  Prospectus  Supplement,  indicates that the
then-current  rating thereof will not be adversely  affected.  The rating of any
series of Certificates by any Rating Agency may be lowered following the initial
issuance  thereof  as a  result  of the  downgrading  or  nonperformance  of the
obligations of any applicable credit support provider,  or as a result of losses
on the  related  Mortgage  Loans in excess of the  levels  contemplated  by such
Rating Agency at the time of its initial rating  analysis.  None of the Company,
the Master  Servicer,  GMAC  Mortgage or any of their  affiliates  will have any
obligation to replace or supplement any credit enhancement, or to take any other
action to maintain any rating of any series of Certificates. See "Description of
Credit Enhancement -- Reduction or Substitution of Credit Enhancement."

         Investment in the Mortgage  Loans.  An investment in securities such as
the Certificates  which generally  represent  interests in mortgage loans may be
affected by, among other things,  a decline in real estate values and changes in
the borrowers' financial condition. No assurance can be given that values of the
Mortgaged  Properties  have remained or will remain at their levels on the dates
of origination of the related  Mortgage Loans.  If the  residential  real estate
market  should  experience an overall  decline in property  values such that the
outstanding  balances of the Mortgage Loans, and any secondary  financing on the
Mortgaged  Properties,  in a particular Mortgage Pool become equal to or greater
than the value of the Mortgaged  Properties,  the actual rates of delinquencies,
foreclosures and losses could be higher than those now generally  experienced in
the mortgage lending industry.  In addition,  in the case of Mortgage Loans that
are subject to negative  amortization,  due to the addition to principal balance
of Deferred  Interest,  the principal  balances of such Mortgage  Loans could be
increased  to an amount  equal to or in  excess  of the value of the  underlying
Mortgaged  Properties,  thereby  increasing  the  likelihood of default.  To the
extent that such losses are not covered by the  applicable  credit  enhancement,
holders of  Certificates  and the owner of the  Excess  Spread,  if any,  of the
series  evidencing  interests in the related Mortgage Pool will bear all risk of
loss resulting  from default by the borrowers  under the Mortgage Loans (each, a
"Mortgagor")  and will  have to look  primarily  to the  value of the  Mortgaged
Properties for recovery of the outstanding  principal and unpaid interest on the
defaulted Mortgage Loans. Certain of the types of loans which may be included in
the  Mortgage  Pools  may  involve  additional   uncertainties  not  present  in
traditional  types of loans. For example,  certain of the Mortgage Loans provide
for escalating or variable payments by the Mortgagor,  as to which the Mortgagor
is  generally  qualified  on the basis of the initial  payment  amount.  In some
instances,  the  Mortgagors  may not be able to make their loan payments as such
payments increase and thus the likelihood of default will increase.  In addition
to the foregoing,


                                        9

<PAGE>



certain  geographic  regions  of the  United  States  from  time  to  time  will
experience  weaker  regional  economic  conditions  and  housing  markets,  and,
consequently,  will experience higher rates of loss and delinquency than will be
experienced  on mortgage  loans  generally.  For  example,  a region's  economic
condition and housing market may be directly, or indirectly,  adversely affected
by natural  disasters or civil  disturbances  such as  earthquakes,  hurricanes,
floods,  eruptions or riots. The economic impact of any of these types of events
may also be felt in areas beyond the region immediately affected by the disaster
or disturbance. The Mortgage Loans underlying certain series of Certificates may
be  concentrated  in these  regions,  and such  concentration  may present  risk
considerations   in   addition   to  those   generally   present   for   similar
mortgage-backed  securities without such concentration.  Moreover,  as described
below,  any  Mortgage  Loan for which a breach of a  representation  or warranty
exists  will  remain in the  related  Trust  Fund in the event  that a Seller is
unable, or disputes its obligation,  to repurchase such Mortgage Loan and such a
breach does not also constitute a breach of a representation made by Residential
Funding, the Company or the Master Servicer. In such event, any resulting losses
generally will be borne by the related form of credit enhancement, to the extent
available.

         Yield  and  Prepayment  Considerations.  The yield to  maturity  of the
Certificates  of each  series  will  depend on the rate and timing of  principal
payments (including  prepayments,  liquidations due to defaults, and repurchases
due to  conversion  of ARM Loans to fixed  interest  rate loans or  breaches  of
representations  and  warranties)  on the  Mortgage  Loans and the price paid by
Certificateholders.  Such yield may be  adversely  affected by a higher or lower
than  anticipated  rate of prepayments  on the related  Mortgage Loans or by the
obtaining of  secondary  financing  by the  Mortgagor.  The yield to maturity on
Strip Certificates will be extremely sensitive to the rate of prepayments on the
related  Mortgage  Loans.  In addition,  the yield to maturity on certain  other
types of classes of Certificates,  including Accrual Certificates,  Certificates
with a  Pass-Through  Rate which  fluctuates  inversely with an index or certain
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. Prepayments are influenced by a number
of factors,  including  prevailing  mortgage market  interest  rates,  local and
regional economic conditions and homeowner mobility.  See "Yield Considerations"
and "Maturity and Prepayment Considerations" herein.


                               THE MORTGAGE POOLS

General

         Unless otherwise specified in the related Prospectus  Supplement,  each
Mortgage Pool will consist primarily of conventional  Mortgage Loans,  excluding
any  interest  retained  by the  Company 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 such  Mortgage  Loans (which may include  Mortgage
Securities).  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 certain other dwelling units,  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   apartment  loans   ("Cooperative   Loans")  evidenced  by
promissory notes  ("Cooperative  Notes") secured by security interests in shares
issued by  cooperatives  and in the  related  proprietary  leases  or  occupancy
agreements  granting  exclusive rights to occupy specific  dwelling units in the
related  buildings.  As used  herein,  unless the context  indicates  otherwise,
"Mortgage Loans" includes  Cooperative 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.

         If specified in the related Prospectus Supplement, a Mortgage Pool will
contain  Mortgage  Loans  that,  in  addition  to being  secured by the  related
Mortgaged  Properties,  are  secured by other  collateral  owned by the  related
Mortgagors  or are  supported by  third-party  guarantees  secured by collateral
owned by the related guarantors.  Such Mortgage Loans are collectively  referred
to herein as "Additional  Collateral Loans," and such collateral is collectively
referred to herein as "Additional Collateral." Additional Collateral may consist
of  marketable  securities,  insurance  policies,  annuities,   certificates  of
deposit,  cash,  accounts  or  other  personal  property  and,  in the  case  of
Additional Collateral owned by any guarantor, may consist of real estate. Unless
otherwise  specified  in  the  related  Prospectus   Supplement,   the  security
agreements  and other similar  security  instruments  related to the  Additional
Collateral  for a  Mortgage  Pool  will,  in the case of  Additional  Collateral
consisting of personal property, create first liens thereon, and, in the case of
Additional  Collateral  consisting of real estate,  create first or second liens
thereon.  Additional  Collateral,  or the liens  thereon in favor of the related
Additional  Collateral Loans, may be greater or less in value than the principal
balances  of such  Additional  Collateral  Loans,  the  Appraised  Values of the
underlying  Mortgaged  Properties  or the  differences,  if  any,  between  such
principal  balances  and  such  Appraised  Values,  and  the  requirements  that
Additional  Collateral be maintained may be terminated upon the reduction of the
Loan-to-Value Ratios or principal balances of the related Additional  Collateral
Loans to certain  pre-determined  amounts.  Additional Collateral (including any
related third-party guarantees) may be provided either in addition to or in lieu
of Primary Insurance Policies for the Additional  Collateral Loans in a Mortgage
Pool, as specified in the related Prospectus  Supplement.  Guarantees supporting
Additional  Collateral  Loans may be  guarantees  of  payment or  guarantees  of
collectability and may be full guarantees or limited  guarantees.  If a Mortgage
Pool includes  Additional  Collateral Loans, the related  Prospectus  Supplement
will specify the nature and extent of such  Additional  Collateral  Loans and of
the related Additional  Collateral.  If specified in such Prospectus Supplement,
the  Trustee,  on behalf of the related  Certificateholders,  will have only the
right to receive  certain  proceeds from the  disposition of any such Additional
Collateral  consisting  of personal  property and the liens  thereon will not be
assigned to the Trustee. No assurance can


                                       10

<PAGE>



be given that values of the Additional  Collateral  have remained or will remain
at  their  levels  on the  Cut-off  Date  or as to  the  timing  of  collections
thereunder from the disposition of such Additional Collateral.  No assurance can
be given as to the amount of proceeds,  if any,  that might be realized from the
disposition  of the Additional  Collateral for any of the Additional  Collateral
Loans. See "Certain Legal Aspects of Mortgage Loans--Anti-Deficiency Legislation
and Other Limitations on Lenders" herein.

         Each  Mortgage  Loan will be selected by the Company for inclusion in a
Mortgage  Pool from among those  purchased  by the Company,  either  directly or
through its affiliates,  including  Residential Funding,  from affiliates of the
Company  including   HomeComings  Financial  Network,  Inc.  and  GMAC  Mortgage
Corporation   ("Affiliated   Sellers"),   or  from   banks,   savings  and  loan
associations,  mortgage  bankers,  investment  banking firms, the FDIC and other
mortgage  loan   originators  or  sellers  not   affiliated   with  the  Company
("Unaffiliated  Sellers";   Unaffiliated  Sellers  and  Affiliated  Sellers  are
collectively  referred to herein as  "Sellers"),  all as  described  below under
"Mortgage  Loan  Program."  If a Mortgage  Pool is composed  of  Mortgage  Loans
acquired by the Company  directly from Sellers other than  Residential  Funding,
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.  Other mortgage loans available for purchase by
the  Company  may have  characteristics  which  would  make  them  eligible  for
inclusion  in a  Mortgage  Pool but  were not  selected  for  inclusion  in such
Mortgage Pool.

         Under  certain  circumstances,  the  Mortgage  Loans will be  delivered
either  directly or indirectly to the Company by one or more Sellers  identified
in the related  Prospectus  Supplement,  concurrently  with the  issuance of the
related  series  of  Certificates  (a  "Designated  Seller  Transaction").  Such
Certificates  may be sold in whole or in part to any such Seller in exchange for
the related  Mortgage  Loans,  or may be offered  under any of the other methods
described  herein  under  "Methods  of  Distribution."  The  related  Prospectus
Supplement  for a Mortgage  Pool  composed  of  Mortgage  Loans  acquired by the
Company  pursuant to a Designated  Seller  Transaction  will  generally  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 Company,  Residential Funding, GMAC Mortgage or any of their affiliates will
make any  representation or warranty with respect to such Mortgage Loans, or any
representation  as to the accuracy or completeness of such information  provided
by the Seller.

         If  specified  in the  related  Prospectus  Supplement,  the Trust Fund
underlying  a series  of  Certificates  may  include  Mortgage  Securities.  The
Mortgage  Securities  may have  been  issued  previously  by the  Company  or an
affiliate thereof, a financial  institution or other entity engaged generally 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
such  trusts,  and  selling  beneficial  interests  in such  trusts.  Except  as
otherwise  set  forth  in  the  related  Prospectus  Supplement,  such  Mortgage
Securities will be generally similar to Certificates  offered  hereunder.  As to
any such series of Certificates,  the related Prospectus Supplement will include
a description of such Mortgage  Securities  and any related credit  enhancement,
and the Mortgage Loans  underlying  such Mortgage  Securities  will be described
together with any other Mortgage Loans included in the Mortgage Pool relating to
such  series.  As to any such  series of  Certificates,  as used herein the term
"Mortgage Pool" includes the Mortgage Loans underlying such Mortgage Securities.
Notwithstanding any other reference herein to the Master Servicer,  with respect
to a series  of  Certificates  as to which  the  Trust  Fund  includes  Mortgage
Securities, the entity that services and administers such Mortgage Securities on
behalf of the holders of such  Certificates may be referred to as the "Manager,"
if so specified in the related Prospectus Supplement. Unless otherwise specified
in the related Prospectus Supplement,  Residential Funding initially will act as
Manager  with  respect  to such  Mortgage  Securities  as  well  as the  related
Certificates,  and references herein to advances to be made and other actions to
be taken by the  Master  Servicer  in  connection  with the  Mortgage  Loans may
include such advances made and other actions taken pursuant to the terms of such
Mortgage Securities.

         Unless  otherwise  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
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 Fund, and
not in any other Mortgage Pool or Trust Fund.


The Mortgage Loans

         Unless  otherwise   specified  below  or  in  the  related   Prospectus
Supplement,  all of the Mortgage  Loans in a Mortgage Pool will (i) have monthly
payments due or deemed to be due on the first of each month,  (ii) be secured by
Mortgaged  Properties  located in any of the 50 states, the District of Columbia
or the  Commonwealth  of  Puerto  Rico  and  (iii)  be of only  one  type 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  ("ARM
         Loans")  having an original  or  modified  term to maturity of not more
         than 30 years with a related interest rate (a "Mortgage Rate")


                                       11

<PAGE>



         which generally 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 sum of a
         fixed  percentage  set forth in the  related  Mortgage  Note (the "Note
         Margin")  and an index*.  The related  Prospectus  Supplement  will set
         forth 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 such ARM Loan  generally  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  generally  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 subject to certain  limitations
         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
         such mortgage loan,  the resulting  amount of interest that has accrued
         but is not  then  payable  ("Deferred  Interest")  will be added to the
         principal balance of such 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 such mortgage loan. Such 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 such 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. Such 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 such
         mortgage loan;

                  (7)  Balloon  mortgage  loans  ("Balloon  Loans"),  which  are
         fixed-rate mortgage loans having original or modified terms to maturity
         of  generally  5 or 7 years  as  described  in the  related  Prospectus
         Supplement, with level monthly payments of principal and interest based
         on a 30-year amortization  schedule.  The amount of the monthly payment
         will remain  constant until the maturity date, upon which date the full
         outstanding  principal  balance  on such  Balloon  Loan will be due and
         payable (such amount, the "Balloon Amount"); or

                  (8) Another  type of mortgage  loan  described  in the related
         Prospectus Supplement.

         Certain  information,  including  information  regarding  loan-to-value
ratios  (each,  a   "Loan-to-Value-Ratio")   at  origination  (unless  otherwise
specified in the related Prospectus Supplement) of the Mortgage Loans underlying
each  series  of  Certificates,  will  be  supplied  in the  related  Prospectus
Supplement.  In the case of purchase Mortgage Loans, the Loan-to-Value  Ratio is
defined  generally as 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 such Mortgage Loan
and (2) the sales price for the related Mortgaged  Property,  except that in the
case of certain  employee or preferred  customer loans,  the denominator of such
ratio may be the sales price. In the case of certain non-purchase Mortgage Loans
including  refinance,  modified or converted  Mortgage Loans, the Loan-to- Value
Ratio  at  origination  is  defined  generally  as  the  ratio,  expressed  as a
percentage,  of the  principal  amount  of  such  Mortgage  Loan to  either  the
appraised value determined in an appraisal  obtained at the time of refinancing,
modification or conversion or, if no such appraisal has been obtained, the value
of the related  Mortgaged  Property  which value  generally will be supported by
either (i) a representation by the related Seller (as described below) as
- --------------------------------------------
         * The  index  (the  "Index")  for a  particular  Mortgage  Pool will be
         specified in the related  Prospectus  Supplement and may include one of
         the following  indexes:  (i) the weekly average yield on U.S.  Treasury
         securities  adjusted to a constant maturity of either three months, six
         months or one year, (ii) the weekly auction average investment yield of
         U.S. Treasury bills of six months, (iii) the daily Bank Prime Loan rate
         made available by the Federal Reserve Board,  (iv) the cost of funds of
         member institutions for the Federal Home Loan Bank of San Francisco, or
         (v) the interbank  offered rates for U.S. dollar deposits in the London
         market,  each calculated as of a date prior to each scheduled  interest
         rate adjustment date which will be specified in the related  Prospectus
         Supplement.



                                       12

to such value,  (ii) a broker's price  opinion,  automated  appraisal,  drive by
appraisal or other  certification of value,  (iii) an appraisal  obtained within
twelve months prior to such refinancing,  modification or conversion or (iv) the
sales price, if the Mortgaged  Property was purchased within the previous twelve
months.  In the case of certain  Mortgage Loans seasoned for over twelve months,
the  Loan-to-Value  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
(i) a statistical analysis,  (ii) a broker's price opinion or (iii) an appraisal
obtained within 120 days of the purchase date (such  Loan-to-Value  Ratio may be
significantly  lower than the ratio determined at origination).  The denominator
of  the  applicable   ratio  described  in  the  preceding  three  sentences  is
hereinafter  referred  to  as  the  "Appraised  Value."  In  connection  with  a
representation by the related Seller as to the value of the Mortgaged  Property,
the Seller  generally  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 such property at the time
of  the  origination  of  the  original   mortgage  loan  or  (ii)  the  current
Loan-to-Value  Ratio  of  such  Mortgage  Loan  generally  meets  the  Company's
underwriting  guidelines.  There can be no assurance  that the substance of such
representation  and  warranty  will be true.  Certain  Mortgage  Loans which are
subject  to  negative  amortization  will have  Loan-to-Value  Ratios  that will
increase  after  origination as a result of such negative  amortization.  In the
case of  certain  seasoned  Mortgage  Loans,  the  values  used  in  calculating
Loan-to-Value  Ratios  may no longer be  accurate  valuations  of the  Mortgaged
Properties, particularly where the Loan-to-Value Ratio was not determined at the
time of purchase as described above. Certain Mortgaged Properties may be located
in regions where property values have declined  significantly  since the time of
origination. In addition, a Loan-to-Value calculation does not take into account
any secondary financing. Under the Company's underwriting standards, a Seller is
generally   permitted   to   provide   secondary   financing   to  a   Mortgagor
contemporaneously  with the  origination of a Mortgage  Loan,  provided that the
combined  Loan-to-Value  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 thereof.  The Mortgage Loans
may be mortgage loans that have been consolidated  and/or have had various terms
changed,  mortgage 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 certain  costs of  construction  of or  improvements  to the
related Mortgaged  Property.  The Appraised Value of any such Mortgaged Property
will be based on the assumption  that such  construction  has been completed (no
inspections of such 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  loan-to-value  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 such  Mortgage  Loan to be faster than that
assumed.

         A Mortgage  Pool may contain ARM Loans  which allow the  Mortgagors  to
convert the  adjustable  rates on such Mortgage  Loans to a fixed rate at one or
more  specified  periods  during  the  life  of such  Mortgage  Loans  (each,  a
"Convertible  Mortgage Loan"),  generally not later than ten years subsequent to
the date of origination. If specified in the related Prospectus Supplement, upon
any  conversion,  the  Company  will  repurchase  or  Residential  Funding,  the
applicable  Subservicer  or a third party will purchase the  converted  Mortgage
Loan as and to the  extent  set  forth  in the  related  Prospectus  Supplement.
Alternatively, if specified in the related Prospectus Supplement, the Company or
Residential  Funding (or another  party  specified  therein) may agree to act as
remarketing  agent with respect to such  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 such  converted  Mortgage  Loan,  the inability of any  remarketing
agent  to  arrange  for  the  sale  of  the  converted  Mortgage  Loan  and  the
unwillingness of such 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,  certain of the
Mortgage  Loans may be subject to temporary  buydown plans  ("Buy-Down  Mortgage
Loans")  pursuant to which the monthly payments made by the Mortgagor during the
early years of the Mortgage Loan (the  "Buy-Down  Period") will be less than the
scheduled monthly payments on the Mortgage Loan, the resulting  difference to be
made up from (i) an  amount  (such  amount,  exclusive  of  investment  earnings
thereon,  being hereinafter  referred to as "Buy-Down Funds") contributed by the
seller of the  Mortgaged  Property  or another  source and placed in a custodial
account (the "Buy-Down Account"),  (ii) if the Buy-Down Funds are contributed on
a present  value  basis,  investment  earnings on such  Buy-Down  Funds or (iii)
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'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.


                                       13

         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 (a "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
Commission within fifteen days after the initial issuance of such  Certificates.
In the event that  Mortgage  Loans are added to or  deleted  from the Trust Fund
after the date of the related Prospectus  Supplement,  such addition or deletion
will be noted in the Form 8-K.

         The Company 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, generally through
other mortgage servicing  institutions  ("Subservicers"),  pursuant to 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
such  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 (the "Certificate  Administrator") for the Trust Fund.
The Certificate  Administrator  may be an affiliate of the Company or the Master
Servicer.  All references herein 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 Company will make certain  limited  representations  and warranties
regarding  the  Mortgage  Loans except as otherwise  specified  herein,  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 certain  purchase
and other  obligations of Subservicers  and Sellers,  as described  herein under
"Mortgage Loan  Program--Representations  by Sellers," "Subservicing by Sellers"
and  "Description of the  Certificates--Assignment  of Mortgage  Loans," and its
obligation  to make  certain  cash  advances  in the event of  delinquencies  in
payments on or with respect to the Mortgage  Loans in amounts  described  herein
under "Description of the  Certificates--Advances")  or pursuant to 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  Company,  either
directly or indirectly through Residential  Funding,  from Sellers. The Mortgage
Loans will  generally  have been  originated  in  accordance  with the Company's
underwriting  standards or alternative  underwriting criteria as described below
under  "Underwriting  Standards"  or as  described  in  the  related  Prospectus
Supplement.

UNDERWRITING STANDARDS

  General Standards

         The Company's  underwriting  standards with respect to certain Mortgage
Loans will generally conform to those published in Residential  Funding's Seller
Guide,  excluding the underwriting  standards  relating to the expanded criteria
program,  the  alternate  program and the home  equity  program  (together  with
Residential  Funding's  Servicer  Guide,  the "Guide," as modified  from time to
time).  The  underwriting  standards as set forth in the Guide are  continuously
revised based on  opportunities  and  prevailing  conditions in the  residential
mortgage  market  and  the  market  for  the  Company's  mortgage   pass-through
certificates.  The Mortgage Loans may be underwritten by Residential  Funding or
by a designated  third party. In certain  circumstances,  however,  the Mortgage
Loans   may   be    underwritten    only   by   the   Seller.    See    "--Guide
Standards--Qualifications  of  Sellers."  Residential  Funding may perform  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 Company's  underwriting  standards,  as well as any
other underwriting  standards that may be applicable to any Mortgage Loans, such
underwriting  standards generally include a set of specific criteria pursuant to
which the  underwriting  evaluation is made.  However,  the  application of such
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  such
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 Company purchases Mortgage Loans which do not conform
to the  underwriting  standards set forth in the Guide.  Certain of the Mortgage
Loans  will  be  purchased  in  negotiated  transactions,  and  such  negotiated
transactions may be governed by agreements  ("Master  Commitments")  relating to
ongoing  purchases of Mortgage  Loans by Residential  Funding,  from Sellers who
will represent that the Mortgage Loans have been  originated in accordance  with
underwriting standards agreed to by Residential Funding. Residential Funding, on
behalf of the  Company,  will  generally  review  only a limited  portion of the
Mortgage  Loans in any delivery of such Mortgage  Loans from the related  Seller
for  conformity  with  the  applicable  underwriting  standards.  Certain  other
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.  The  Company,  or  Residential  Funding  on behalf of the
Company,   may  accept  a  certification   from  such  insurance  company  or  a
confirmation  by such 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 or the Company.

         The level of review by Residential  Funding or the Company,  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 (i) factors relating
to the  experience  and status of the Seller,  and (ii)  characteristics  of the
specific  Mortgage  Loan,  including the principal  balance,  the  Loan-to-Value
Ratio, the loan type or loan program,  and (iii) 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 Company).
Generally,  such  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 certain loan features (such
as maximum loan amount,  maximum Loan-to-Value 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  set forth in the Guide.  Such  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 Company
or Residential Funding.  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 standards as described above will be equivalent
under all  circumstances.  In the case of a Designated Seller  Transaction,  the
applicable underwriting standards will


                                       15

<PAGE>



be those of the Seller or of the originator of the Mortgage  Loans,  and will be
described in the related Prospectus Supplement.

         The Company, either directly or indirectly through Residential Funding,
will also purchase  Mortgage Loans from its affiliates,  including GMAC Mortgage
Corporation and HomeComings Financial Network, Inc., with underwriting standards
generally in accordance with the Guide or as otherwise agreed to by the Company.
However, in certain limited  circumstances,  such Mortgage Loans may be employee
or preferred  customer  loans with  respect to which,  in  accordance  with such
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,  or its
affiliates, in certain limited circumstances  preferential interest rates may be
allowed, and Primary Insurance Policies may not be required in connection with a
Loan-to-Value  Ratio  over 80%.  As to any series of  Certificates  representing
interests in such Mortgage Loans,  credit  enhancement may be provided  covering
losses on such Mortgage Loans to the extent that such losses would be covered by
Primary Insurance  Policies if obtained,  in the form of a corporate guaranty or
in  certain  other  forms   described   herein  under   "Description  of  Credit
Enhancement."  Neither  the  Company  nor  Residential  Funding  will review any
affiliate's  mortgage loans for conformity with the  underwriting  standards set
forth in the Guide.


  Guide Standards

         The following is a brief description of the underwriting  standards set
forth  in  the  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  such  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 above under "The Mortgage Pools--The Mortgage Loans."

         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 (such as
property taxes and hazard insurance) and other financial obligations and monthly
living  expenses.  The Company will  generally  underwrite  ARM Loans,  Buy-Down
Mortgage  Loans,  graduated  payment  Mortgage  Loans and certain 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 such
increase even though the borrowers may not be able to make such higher  payments
at the time of  origination.  The Mortgage  Rate in effect from the  origination
date of an ARM Loan or certain other types of loans to the first adjustment date
generally will 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 such 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 generally 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 such  refinancing  will be
available to the borrower or that such a sale will be possible.

         The  underwriting  standards  set forth in the Guide  will be varied in
appropriate cases, including "limited" or "reduced loan documentation"  mortgage
loan programs.  Certain reduced loan documentation programs, for example, do not
require income,  employment or asset  verifications.  Generally,  in order to be
eligible for a reduced loan documentation  program, the Loan-to-Value Ratio must
meet applicable guidelines, the borrower must have a good credit history and the
borrower's  eligibility  for such 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 such  representation and warranty,  neither the Company,
Residential Funding 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 Loan-


                                       16

<PAGE>



to-Value  Ratio  with  respect  to such  Mortgage  Loan will be higher  than the
Loan-to-Value  Ratio set forth with  respect  thereto in the related  Prospectus
Supplement.

         In its  evaluation of mortgage loans which have more than twelve months
of payment  experience,  Residential  Funding generally places greater weight on
payment history and may take into account market and other economic trends while
placing  less  weight  on  underwriting   factors  generally  applied  to  newly
originated  mortgage  loans.  Certain  Mortgage  Loans  seasoned for over twelve
months may be  underwritten  for purchase by  Residential  Funding  based on the
borrower's   credit  score  and  payment   history,   with  no  current   income
verification,  and under alternative  property valuation methods described above
under "The Mortgage Pools--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 property for
repayment  in the  event of  foreclosure.  See  "Certain  Legal  Aspects  of the
Mortgage  Loans--Anti-Deficiency  Legislation and Other Limitations on Lenders."
The  Company'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 such value will support the loan balance in the future.


Qualifications of Sellers

         Except with  respect to  Designated  Seller  Transactions,  each Seller
(other  than  the  Federal  Deposit  Insurance   Corporation  (the  "FDIC")  and
investment  banking  firms) will have been approved by  Residential  Funding for
participation  in Residential  Funding's loan purchase  program.  In determining
whether to  approve a seller for  participation  in the loan  purchase  program,
Residential  Funding generally 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 Fund 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,  such institution may continue to be treated as a Seller.  Any such
event may adversely affect the ability of any such Seller to repurchase Mortgage
Loans in the event of a breach of a  representation  or  warranty  which has not
been cured.

         Residential  Funding generally monitors which Sellers are under control
of the FDIC or are insolvent,  otherwise in receivership or  conservatorship  or
financially  distressed.  Such Seller 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). The FDIC may have no
obligation to repurchase any Mortgage Loan for a breach of a representation  and
warranty.

         Unless otherwise  specified in the related Prospectus  Supplement,  the
qualifications  required  of Sellers  for  approval  by  Residential  Funding 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 Company,  Residential Funding
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

         Each Seller generally will make certain  representations and warranties
with respect to the Mortgage Loans sold by such Seller. Such representations and
warranties  generally include,  among other things, that at the time of the sale
by the Seller to  Residential  Funding of each Mortgage  Loan: (i) 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 Company or
Residential  Funding;  (ii) the Seller has good title to each such Mortgage Loan
and such  Mortgage  Loan was  subject to no offsets,  defenses or  counterclaims
except as may be provided under the Relief Act and except to the extent that any
buydown  agreement  exists  for a Buy-Down  Mortgage  Loan;  (iii)  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);  (iv)
to the best of the  Seller's  knowledge,  each  Mortgaged  Property is free from
damage and in good repair;  (v) there are no  delinquent  tax or, to the best of
the Seller's knowledge,  assessment liens against the Mortgaged  Property;  (vi)
each  Mortgage Loan is current as to all required  payments;  (vii) if a Primary
Insurance Policy is required with respect to a Mortgage Loan, such Mortgage Loan
is the  subject of such a policy;  and  (viii)  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


                                       17

<PAGE>



obligated to repurchase such Mortgage Loan as described  below.  However,  there
can be no assurance  that a Seller will honor its  obligation to repurchase  any
Mortgage Loan as to which such a breach of a representation  or warranty arises.
Any costs  associated with enforcing the Seller's  obligation to repurchase such
Mortgage Loan will be borne by the related Trust Fund.

         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. Generally,  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 in respect of a
Mortgage  Loan will have been made as of the date on which such  Seller sold the
Mortgage Loan to the Company or Residential  Funding;  the date as of which such
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 Company or  Residential  Funding,  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 Company from Sellers through Residential  Funding,  Residential  Funding,
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,  will also have made certain limited  representations and
warranties  regarding the Mortgage  Loans to the Company at the time (just prior
to the initial  issuance of the related  series of  Certificates)  that they are
sold to the Company. Such representations and warranties will generally include,
among other things,  that: (i) 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; (ii) except in the case of Cooperative Loans, either a policy of title
insurance  in the  form  and  amount  required  by the  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 Company;  (iii) to the best of Residential  Funding's knowledge,  if
required, the Mortgage Loans are the subject of a Primary Insurance Policy; (iv)
Residential  Funding 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; (v) to the best of Residential Funding's knowledge, each
Mortgaged  Property is free of damage and is in good repair;  (vi) each Mortgage
Loan complied in all material  respects  with all  applicable  local,  state and
federal laws at the time of origination;  (vii) except as otherwise indicated in
the  related  Prospectus  Supplement,  no  Mortgage  Loan is one  month  or more
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 (viii)  there is no  delinquent  tax or, to the best of
Residential Funding's knowledge, assessment lien against any Mortgaged Property.
In the event of a breach of a  representation  or warranty  made by  Residential
Funding   that   materially    adversely    affects   the   interests   of   the
Certificateholders in a Mortgage Loan,  Residential Funding will be obligated to
repurchase or substitute for such Mortgage Loan as described below. In addition,
Residential  Funding  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 such Mortgage
and certain 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 Company delivers to
the Trustee or the custodian an affidavit  certifying that the original Mortgage
Note has been  lost or  destroyed,  if such  Mortgage  Loan  subsequently  is in
default and the  enforcement  thereof or of the related  Mortgage is  materially
adversely  affected by the absence of the original  Mortgage  Note,  Residential
Funding will be obligated to repurchase or substitute  for such Mortgage Loan in
the manner described below. However, Residential Funding will not be required to
repurchase or substitute for any Mortgage Loan if the circumstances  giving rise
to such  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 certain 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  nor any  Seller  will be
required to purchase or  substitute  for any  Mortgage  Loan as a result of such
prepayment or modification.

         The  Company  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
insofar as such agreement relates to the  representations and warranties made by
a Seller or Residential Funding, as the case may be, in respect of such Mortgage
Loan  and  any  remedies  provided  for  with  respect  to any  breach  of  such
representations and warranties.  If a Seller or Residential Funding, 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 such Mortgage Loan within 90 days after notice from
the Master Servicer, such


                                       18

<PAGE>



Seller or Residential Funding, as the case may be, will be obligated to purchase
such  Mortgage Loan at a price (the  "Purchase  Price") set forth in the related
Pooling and Servicing  Agreement which Purchase Price will generally 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 in
respect  of master  servicing  compensation  or  subservicing  compensation,  as
applicable, and, if applicable, the Excluded Spread).

         Unless otherwise specified in the related Prospectus Supplement,  as to
any such  Mortgage  Loan  required to be  purchased  by  Residential  Funding as
provided above,  rather than repurchase the Mortgage Loan,  Residential  Funding
may, at its sole option,  remove such Mortgage Loan (a "Deleted  Mortgage Loan")
from the Trust Fund and cause the  Company to  substitute  in its place  another
Mortgage Loan of like kind (a "Qualified  Substitute  Mortgage Loan");  however,
such  substitution  must be effected  within 120 days of the date of the initial
issuance  of the  Certificates  with  respect to a Trust Fund for which no REMIC
election is to be made.  With respect to a Trust Fund for which a REMIC election
is to be  made,  except  as  otherwise  provided  in the  Prospectus  Supplement
relating to a series of Certificates,  such 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 such substitution would cause the Trust
Fund to not qualify as a REMIC or result in a prohibited  transaction  tax under
the Code.

         Except as otherwise provided in the related Prospectus Supplement,  any
Qualified  Substitute Mortgage Loan generally will, on the date of substitution,
(i) 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 (the amount of
any shortfall to be deposited in a custodial  account (the "Custodial  Account")
in the month of substitution for distribution to the  Certificateholders),  (ii)
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, (iii)
have a  Loan-to-Value  Ratio at the time of  substitution no higher than that of
the Deleted  Mortgage  Loan at the time of  substitution,  (iv) have a remaining
term to maturity not greater than (and not more than one year less than) that of
the Deleted  Mortgage Loan, and (v) 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,  as the case may be, fails to honor such  obligation.  The
Master  Servicer  will be entitled to  reimbursement  for any costs and expenses
incurred in pursuing such a 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 set forth in the
preceding  sentence,  may  negotiate  and  enter  into  one or  more  settlement
agreements  with such Seller that could  provide for,  among other  things,  the
purchase of only a portion of the affected Mortgage Loans or coverage of certain
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 such remedies if it determines  that one
such 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 such 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
Company's or Residential  Funding's  representations has occurred,  the Seller's
purchase  obligation will not become an obligation of the Company or Residential
Funding.  In the case of a Designated Seller  Transaction where the Seller fails
to repurchase a Mortgage Loan and neither the Company,  Residential  Funding nor
any other entity has assumed the representations and warranties, such repurchase
obligation  of the  Seller  will not  become an  obligation  of the  Company  or
Residential  Funding.  Unless  otherwise  specified  in the  related  Prospectus
Supplement,   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 in its capacity as a seller
of Mortgage  Loans to the  Company,  or for any other event  giving rise to such
obligations as described above.

         Neither  the  Company  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 such  obligations  with
respect to  Mortgage  Loans.  Such a default by a Seller is not a default by the
Company 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,  as set  forth  above,  or by the
Company or the Master  Servicer,  as described  below under  "Description of the
Certificates--Assignment of Mortgage Loans," Residential Funding, the Company or
the Master Servicer may have a purchase or substitution obligation. Any Mortgage
Loan not so


                                       19

<PAGE>



purchased  or  substituted  for shall  remain in the related  Trust Fund 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's consent to the transfer of subservicing rights relating to
any Mortgage Loans to a successor servicer, Residential Funding may release such
Seller from liability under its representations and warranties  described above,
upon the  assumption of such  successor  servicer of the Seller's  liability for
such  representations  and  warranties  as of the date they were  made.  In that
event, Residential Funding's rights under the instrument by which such successor
servicer  assumes the Seller's  liability  will be assigned to the Trustee,  and
such  successor  servicer shall be deemed to be the "Seller" for purposes of the
foregoing provisions.


Subservicing

         The Seller of a Mortgage Loan will generally act as the Subservicer for
such Mortgage Loan pursuant to an agreement between  Residential Funding and the
Subservicer (a  "Subservicing  Agreement")  unless  servicing is released to the
Master  Servicer or has been  transferred to a servicer  approved by Residential
Funding.  The  Master  Servicer  may,  but  is not  obligated  to,  assign  such
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 certain
Mortgage Loans sold in negotiated transactions will generally vary from the form
filed  herewith to  accommodate  the  different  features of the Mortgage  Loans
included in such a  Designated  Seller  Transaction  and to vary the  parameters
constituting an event of default. The following  description does not purport to
be  complete  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 such  Subservicing  Agreement will be a contract solely between the Master
Servicer and the Subservicer,  the Pooling and Servicing  Agreement  pursuant to
which a series of  Certificates  is issued will provide  that, if for any reason
the Master  Servicer  for such  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 such
Subservicing Agreement.

         With the approval of the Master  Servicer,  a Subservicer  may delegate
its servicing  obligations to third-party  servicers,  but such 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 such collections to the
Master  Servicer;  maintenance of hazard  insurance and filing and settlement of
claims thereunder,  subject in certain 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  pursuant  to 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. A Subservicer  may also be required to supervise  foreclosures  and under
certain  circumstances  inspect and manage Mortgaged  Properties.  A Subservicer
will also be  obligated  to make  advances to the Master  Servicer in respect of
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 certain 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
such  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.  Unless  otherwise  specified  in the  related
Prospectus  Supplement,  a Subservicer may transfer its servicing obligations to
another entity that has been approved for participation in Residential Funding'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
certain  expenditures  which it makes,  generally  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
Company or  Residential  Funding,  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.



                                       20

<PAGE>



         Each  Subservicer  will be  required  to  service  each  Mortgage  Loan
pursuant to the terms of the Subservicing  Agreement for the entire term of such
Mortgage Loan,  unless the Subservicing  Agreement is earlier  terminated by the
Master Servicer or unless servicing is released to the Master Servicer.  Subject
to applicable  law, the Master  Servicer may generally  terminate a Subservicing
Agreement  immediately  upon the giving of notice upon  certain  stated  events,
including the violation of such  Subservicing  Agreement by the Subservicer,  or
upon sixty days'  notice to the  Subservicer  without  cause upon  payment of an
amount generally equal to 2% of the aggregate  outstanding  principal balance of
all mortgage loans,  including the Mortgage Loans,  serviced by such Subservicer
pursuant to 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  such  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 the  liability  for such
representations  and warranties will not be assumed by such new Subservicer.  In
the event of such an assumption,  the Master Servicer may in the exercise of its
business  judgment release the terminated  Subservicer from liability in respect
of  such  representations  and  warranties.  Any  amendments  to a  Subservicing
Agreement or to a new Subservicing  Agreement may contain  provisions  different
from those  described  above  which are in effect in the  original  Subservicing
Agreements.  However,  the Pooling and  Servicing  Agreement for each Trust Fund
will provide that any such  amendment or new agreement  may not be  inconsistent
with or violate  such  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 certain  instances,  two or more series of Certificates)  will be issued
pursuant to a Pooling and Servicing Agreement, similar to one of the forms filed
as an exhibit to the Registration  Statement of which this Prospectus is a part.
Each Pooling and  Servicing  Agreement  will be filed with the  Commission as an
exhibit  to a Form  8-K.  The  following  summaries  (together  with  additional
summaries under "The Pooling and Servicing  Agreement"  below) describe  certain
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 Fund and the related  Prospectus
Supplement.

         Unless otherwise specified in the Prospectus Supplement with respect to
a series,  Certificates  of each  series  covered by a  particular  Pooling  and
Servicing Agreement will evidence specified  beneficial ownership interests in a
separate Trust Fund created pursuant to such Pooling and Servicing Agreement.  A
Trust Fund will consist of, to the extent  provided in the Pooling and Servicing
Agreement:  (i) such  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 Company or any
of its  affiliates  with respect to each such  Mortgage  Loan;  (ii) such assets
including,  without  limitation,  all payments and collections in respect of the
Mortgage  Loans or Mortgage  Securities  due after the related  Cut-off Date, as
from  time to time  are  identified  as  deposited  in  respect  thereof  in the
Custodial  Account  and in  the  related  Certificate  Account;  (iii)  property
acquired by  foreclosure  of such Mortgage  Loans or deed in lieu of foreclosure
and certain proceeds from the disposition of any related Additional  Collateral;
(iv) hazard  insurance  policies  and Primary  Insurance  Policies,  if any, and
certain  proceeds  thereof;  and  (v)  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  Bond,  Certificate  Insurance  Policy,  Surety Bond or other type of
credit  enhancement as described under  "Description of Credit  Enhancement." To
the  extent  that  any  Trust  Fund   includes   certificates   of  interest  or
participations  in  Mortgage  Loans,  the  related  Prospectus  Supplement  will
describe  the  material   terms  and   conditions   of  such   certificates   or
participations.

         Each series of Certificates  may consist of any one or a combination of
the following:  (i) a single class of Certificates;  (ii) two or more classes of
Certificates,  one or more classes of which may be Senior  Certificates that are
senior in right of payment to any class or classes of Mezzanine Certificates and
to any other  class or  classes  of  Subordinate  Certificates,  and as to which
certain classes of Senior (or  Subordinate)  Certificates may be senior to other
classes of Senior (or Subordinate) Certificates,  as described in the respective
Prospectus  Supplement (any such series, a "Senior/Subordinate  Series");  (iii)
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;  (iv) 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 certain accrued interest will not be
distributed  but rather will be added to the principal  balance  thereof on each
Distribution Date for the period described in the related Prospectus Supplement;
or (v) 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  Bond,  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 person appointed under the related Pooling and Servicing Agreement
to register the Certificates  (the "Certificate  Registrar").  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" as used herein
refers to the entity  whose  name  appears  on the  records  of the  Certificate
Registrar  (or,  if  applicable,  a  transfer  agent) as the  registered  holder
thereof, except as otherwise indicated in the related Prospectus Supplement.

         If  issued  in  book-entry  form,   certain  classes  of  a  series  of
Certificates  will be initially issued through the book-entry  facilities of The
Depository Trust Company  ("DTC"),  or Cedel Bank, SA ("CEDEL") or the Euroclear
System  ("Euroclear")  (in Europe) if they are participants of such systems,  or
indirectly  through  organizations  which are  participants in such systems,  or
through  such other  depository  or facility as may be  specified in the related
Prospectus  Supplement.   As  to  any  such  class  of  Certificates  so  issued
("Book-Entry  Certificates"),  the record  holder of such  Certificates  will be
DTC's  nominee.  CEDEL and  Euroclear  will hold omnibus  positions on behalf of
their  participants  through  customers'  securities  accounts  in  CEDEL's  and
Euroclear's names on the books of their


                                       22

<PAGE>



respective  depositaries  (the  "Depositaries"),  which in turn  will  hold such
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   participating
organizations  ("DTC  Participants,"  and together  with the CEDEL and Euroclear
participating  organizations,  "Participants") and facilitates the clearance and
settlement of securities  transactions  between  Participants through electronic
book-entry  changes  in  the  accounts  of  Participants.  Participants  include
securities brokers and dealers, banks, trust companies and clearing corporations
and may include certain other  organizations.  Other  institutions  that are not
Participants  but clear  through  or  maintain  a  custodial  relationship  with
Participants (such institutions,  "Indirect  Participants") have indirect access
to DTC's clearance system.


         Unless otherwise  specified in the related  Prospectus  Supplement,  no
person acquiring an interest in any Book-Entry  Certificate (each such person, a
"Beneficial Owner") will be entitled to receive a Certificate  representing such
interest in registered,  certificated  form, unless either (i) DTC ceases to act
as depository in respect thereof and a successor depository is not obtained,  or
(ii) the Company elects in its sole discretion to discontinue  the  registration
of such  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 such
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 such 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 such  Certificates,  may be
limited   because  of  the  lack  of  physical   certificates   evidencing  such
Certificates and because DTC may act only on behalf of Participants.

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

         Transfers between Participants will occur in accordance with DTC rules.
Transfers  between CEDEL  Participants and Euroclear  Participants will occur in
accordance with their respective rules and operating procedures.

         Cross-market  transfers  between persons holding directly or indirectly
through  DTC,  on the  one  hand,  and  directly  or  indirectly  through  CEDEL
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance  with DTC  rules on  behalf of the  relevant  European  international
clearing  system  by the  relevant  Depositaries;  however,  such  cross  market
transactions  will require  delivery of  instructions  to the relevant  European
international  clearing system by the  counterparty in such system in accordance
with its rules and procedures  and within its  established  deadlines  (European
time).  The  relevant  European  international  clearing  system  will,  if  the
transaction  meets its  settlement  requirements,  deliver  instructions  to 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. CEDEL
Participants and Euroclear Participants may not deliver instructions directly to
the Depositaries.

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

         Euroclear was created to hold securities for  participants of Euroclear
("Euroclear   Participants")  and  to  clear  and  settle  transactions  between
Euroclear  Participants  through  simultaneous  electronic  book-entry  delivery
against  payment,   thereby  eliminating  the  need  for  physical  movement  of
certificates and any risk from lack of simultaneous  transfers of securities and
cash.  Euroclear is operated by the Brussels,  Belgium office of Morgan Guaranty
Trust  Company  of New York (the  "Euroclear  Operator"),  under  contract  with
Euroclear  Clearance  Systems  S.C.,  a Belgian  co-operative  corporation  (the
"Clearance  Cooperative").   All  operations  are  conducted  by  the  Euroclear
Operator,  and all Euroclear  securities  clearance  accounts and Euroclear cash
accounts  are  accounts   with  the  Euroclear   Operator,   not  the  Clearance
Cooperative.  The  Clearance  Cooperative  establishes  policy for  Euroclear on
behalf of Euroclear  Participants.  The Euroclear Operator is the Belgian branch
of a New York banking  corporation which is a member bank of the Federal Reserve
System.  As such,  it is regulated and examined by the Board of Governors of the
Federal Reserve System and the New York State Banking Department, as well as the
Belgian Banking Commission. Securities clearance accounts and cash accounts with
the Euroclear Operator are governed by the Terms and Conditions Governing Use of
Euroclear  and the related  Operating  Procedures  of the  Euroclear  System and
applicable Belgian law (collectively, the "Terms and Conditions"). The Terms and
Conditions govern transfers of securities and cash within Euroclear, withdrawals
of securities and cash from Euroclear, and


                                       23

<PAGE>



receipts of payments with respect to securities in Euroclear.  All securities in
Euroclear  are  held  on  a  fungible  basis  without  attribution  of  specific
certificates to specific securities clearance accounts.

         Distributions  in  respect  of  the  Book-Entry  Certificates  will  be
forwarded by the Trustee to DTC, and DTC will be responsible for forwarding such
payments to Participants,  each of which will be responsible for disbursing such
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 such
actions.  None of the Master Servicer,  the Company, 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 such beneficial ownership interests.


Assignment of Trust Fund Assets

         At the time of issuance of a series of  Certificates,  the Company will
cause the  Mortgage  Loans or Mortgage  Securities  and any other  assets  being
included in the related  Trust Fund 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
such 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 such assignment,  deliver a series
of  Certificates  to the Company 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.  Such  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  Loan-to-  Value Ratio at
origination or modification (without regard to any secondary financing).

         In addition,  the Company  will,  as to each  Mortgage  Loan other than
Mortgage Loans underlying any Mortgage Securities, deliver to the Trustee (or to
the Custodian) (as described  below)  certain legal  documents  relating to such
Mortgage Loan that are in possession of the Company, including: (i) 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);  (ii) 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; (iii) an assignment in recordable form
of the Mortgage (or,  with respect to a  Cooperative  Loan, an assignment of the
related proprietary lease or occupancy agreement);  and (iv) if applicable,  any
riders or  modifications  to such  Mortgage  Note and  Mortgage,  together  with
certain  other  documents at such times as set forth in the related  Pooling and
Servicing  Agreement.  Such  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  Fund may  include
Mortgage Loans where the original  Mortgage Note is not delivered to the Trustee
if the Company  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  thereof  has been lost or  destroyed.  With  respect to such  Mortgage
Loans, the Trustee (or its nominee) may not be able to enforce the Mortgage Note
against the related  borrower.  Residential  Funding will agree to repurchase or
substitute for such a Mortgage Loan in certain circumstances (see "Mortgage Loan
Program--Representations by Sellers").

         In the event  that,  with  respect to any  Mortgage  Loan,  the Company
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  Company  will  deliver  or  cause to be  delivered  to the  Trustee  or the
Custodian a true and correct  photocopy  of such  Mortgage  or  assignment.  The
Company 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,  such 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 Company or the  originator of such  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 such Mortgage  Loans either (i) secure a specific  obligation for the
benefit of a specified  person (a "Direct Puerto Rico  Mortgage") or (ii) secure
an  instrument   transferable  by  endorsement   (an  "Endorsable   Puerto  Rico
Mortgage").  Endorsable  Puerto Rico  Mortgages do not require an  assignment to
transfer  the  related  lien.  Rather,  transfer  of such  mortgages  follows an
effective  endorsement of the related Mortgage Note and, therefore,  delivery of
the  assignment  referred to in clause (iii) of the second  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
such assignment would be delivered to the Trustee (or the Custodian).

                                       24

<PAGE>



         The Trustee or the Custodian  will hold such documents in trust for the
benefit of the  Certificateholders,  and generally  within 45 days after receipt
thereof,  will review such documents.  Unless otherwise  provided in the related
Prospectus  Supplement,  if any such  document is found to be  defective  in any
material respect,  the Trustee or the Custodian shall promptly notify the Master
Servicer  and the  Company,  the  former  of  which  shall  notify  the  related
Subservicer  or Seller,  as the case may be. If such  Subservicer or Seller does
not cure the  omission  or defect  within 60 days  after  notice is given to the
Master  Servicer,  such  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    above   under    "Mortgage    Loan
Program--Representations  by Sellers"  but subject to the  provisions  described
below 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 as described above.  Unless otherwise specified in
the related Prospectus  Supplement,  neither the Master Servicer nor the Company
will be  obligated  to  purchase or  substitute  for such  Mortgage  Loan if the
Subservicer or Seller,  as the case may be, defaults on its obligation to do so.
Unless otherwise specified in the related Prospectus  Supplement,  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 Fund.

         The  Trustee  will be  authorized  at any time to  appoint  one or more
custodians (each, a "Custodian")  pursuant to a custodial  agreement to maintain
possession of and review  documents  relating to the Mortgage Loans as the agent
of the Trustee. The identity of such Custodian, if any, 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 Company will make certain limited representations and warranties
as to the types and geographical concentrations of such Mortgage Loans and as to
the accuracy,  in all material respects,  of certain identifying  information in
respect  of  each  such  Mortgage  Loan  (e.g.,  original  Loan-to-Value  Ratio,
principal  balance as of the Cut-off Date,  Mortgage Rate and maturity).  Upon a
breach  of any  such  representation  which  materially  adversely  affects  the
interests  of the  Certificateholders  in a Mortgage  Loan,  the Company will be
obligated to cure the breach in all material respects,  to purchase the Mortgage
Loan at its  Purchase  Price  or,  unless  otherwise  specified  in the  related
Prospectus  Supplement,  to  substitute  for  such  Mortgage  Loan  a  Qualified
Substitute Mortgage Loan in accordance with the provisions for such substitution
by   Residential    Funding   as   described    above   under   "Mortgage   Loan
Program--Representations  by Sellers." However, the Company 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  any  such  breach  also
constitutes  fraud in the  origination  of the  related  Mortgage  Loan.  Unless
otherwise  specified  in the related  Prospectus  Supplement,  this  purchase or
substitution    obligation    constitutes   the   sole   remedy   available   to
Certificateholders  or the  Trustee for such a breach of  representation  by the
Company.  Any Mortgage Loan not so purchased or substituted  for shall remain in
the related Trust Fund.

         The Master  Servicer will make certain  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
such  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 such  Mortgage  Loan) or,  unless
otherwise specified in the related Prospectus Supplement, to substitute for such
Mortgage  Loan a  Qualified  Substitute  Mortgage  Loan in  accordance  with the
provisions  for  such   substitution   described   above  under  "Mortgage  Loan
Program--Representations  by Sellers." Unless otherwise specified in the related
Prospectus Supplement,  this purchase or substitution obligation will constitute
the sole remedy available to Certificateholders or the Trustee for such a breach
of representation by the Master Servicer.  Any Mortgage Loan not so purchased or
substituted for shall remain in the related Trust Fund.

         Pursuant to each Pooling and Servicing Agreement,  the Master Servicer,
either  directly  or through  Subservicers,  will  service  and  administer  the
Mortgage Loans assigned to the Trustee as more fully set forth below.


Spread

         The Company,  the Master Servicer or any of their  affiliates,  or such
other entity as may be 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 such  portion of interest  will be
disclosed in the related Prospectus Supplement.  This payment may be in addition
to any  other  payment  (such as the  servicing  fee)  that any such  entity  is
otherwise  entitled to receive with  respect to the  Mortgage  Loans or Mortgage
Securities.  Any such  payment  in  respect of the  Mortgage  Loans or  Mortgage
Securities  will represent a specified  portion of the interest  payable thereon
and as specified in the related  Prospectus  Supplement,  will either be part of
the assets  transferred to the related Trust Fund (the "Excess  Spread") or will
be excluded from the assets transferred to the related Trust Fund (the "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 pursuant to a Subservicing
Agreement  will establish and maintain an account (the  "Subservicing  Account")
which generally meets the requirements set forth in the Guide from time to time,
and is otherwise  acceptable to the Master Servicer. A Subservicing Account must
be  established  with a Federal Home Loan Bank or with a depository  institution
(including  the  Subservicer  itself) whose accounts are insured by the National
Credit  Union  Share  Insurance  Fund  or the  FDIC,  and  any  such  depository
institution  must meet certain  minimum rating  criteria set forth in the Guide.
Except as otherwise permitted by the applicable Rating Agencies,  a Subservicing
Account  generally  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 may be held therein.

         A Subservicer is required to deposit into its Subservicing Account on a
daily   basis   all   amounts    described    above   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 such 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,  certain  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  Fund  by  deed  in  lieu  of
foreclosure.  The  Certificateholders are not entitled to any such 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 such  Subservicer  prior to the first day of the  following
month,  from the date of  application  of such  payment  to the first day of the
following month.

         The Master Servicer will deposit or will cause to be deposited into the
Custodial Account certain 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  set forth in the related  Pooling and Servicing  Agreement,  which
(except as otherwise provided therein) generally will include the following:

                  (i) all payments on account of principal of the Mortgage Loans
         comprising a Trust Fund;

                  (ii) all payments on account of interest on the Mortgage Loans
         comprising  such Trust Fund, net of the portion of each payment thereof
         retained  by the  Subservicer,  if  any,  as  its  servicing  or  other
         compensation;

                  (iii) all amounts (net of  unreimbursed  liquidation  expenses
         and insured  expenses  incurred,  and unreimbursed  Servicing  Advances
         made, by the related  Subservicer)  received and retained in connection
         with the liquidation of any defaulted  Mortgage Loan, by foreclosure or
         otherwise  ("Liquidation  Proceeds"),  including  all  proceeds  of any
         Special  Hazard  Insurance  Policy,   Bankruptcy  Bond,  Mortgage  Pool
         Insurance  Policy,  Primary  Insurance Policy and any title,  hazard or
         other insurance  policy or guaranty  covering any Mortgage Loan in such
         Mortgage Pool  (together  with any payments under any Letter of Credit,
         "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;

                  (iv)  any  Buy-Down  Funds  (and,  if  applicable,  investment
         earnings  thereon)  required  to  be  paid  to  Certificateholders,  as
         described below;

                  (v) all  proceeds  of any  Mortgage  Loan in such  Trust  Fund
         purchased  (or,  in  the  case  of  a  substitution,   certain  amounts
         representing  a  principal  adjustment)  by the  Master  Servicer,  the
         Company,  Residential  Funding,  any Subservicer or Seller or any other
         person  pursuant to the terms of the Pooling and  Servicing  Agreement.
         See "Mortgage Loan  Program--Representations by Sellers," "--Assignment
         of Mortgage Loans" above and "Purchase Obligations;"

                  (vi)  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 below; and

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

         In  addition  to  the  Custodial  Account,  the  Master  Servicer  will
establish  and  maintain,  in the name of the  Trustee  for the  benefit  of the
holders of each  series of  Certificates,  an account  for the  disbursement  of
payments on the Mortgage  Loans  evidenced by each series of  Certificates  (the
"Certificate  Account").  Both the Custodial Account and the Certificate Account
must  be  either  (i)  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


                                       26

<PAGE>



series not less than a specified level comparable to the rating category of such
Certificates,  (ii) 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  such 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  such funds that is superior to the claims of any other  depositors  or
creditors of the depository institution with which such accounts are maintained,
(iii)  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 certain rating  criteria,  (iv) in the case of the Certificate  Account,  a
trust account or accounts maintained with the Trustee, or (v) such other account
or accounts acceptable to any applicable Rating Agency (an "Eligible  Account").
The  collateral  that is  eligible to secure  amounts in an Eligible  Account is
limited to certain permitted investments,  which are generally limited to United
States  government  securities and other investments that are rated, at the time
of  acquisition,  in one of the categories  permitted by the related Pooling and
Servicing  Agreement  ("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  below.  The
Custodial Account may contain funds relating to more than one series of Mortgage
Pass-Through  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 set forth 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 such  Distribution  Date.  The
Master  Servicer or the Trustee will also deposit or cause to be deposited  into
the  Certificate  Account:  (i) the  amount of any  advances  made by the Master
Servicer as described  herein under  "--Advances,"  (ii) 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, (iii) 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, (iv) any
distributions received on any Mortgage Securities included in the Trust Fund and
(v) any  other  amounts  as set  forth  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  generally 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 such  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 such
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  set  forth  herein  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 such funds  pursuant to the related  buydown plan
or (ii) if such 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 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  Company  will be  obligated  to add to any  such  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
such  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 above 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
such 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 Fund.

         If the Mortgagor on a Buy-Down Mortgage Loan prepays such 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 such 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 generally 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  certain  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


                                       27

<PAGE>



after prepayment or after termination of the Buy-Down Period will be remitted to
the related  Mortgagor or such other  designated party pursuant to the agreement
relating to each  Buy-Down  Mortgage  Loan (the  "Buy-Down  Agreement").  If the
Mortgagor  defaults  during  the  Buy-Down  Period  with  respect  to a Buy-Down
Mortgage Loan and the property  securing such Buy-Down  Mortgage Loan is sold in
liquidation  (either by the Master Servicer,  the Primary  Insurer,  the insurer
under the  Mortgage  Pool  Insurance  Policy (the "Pool  Insurer")  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 such insurer and such 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 set forth in the related
Pooling and Servicing  Agreement,  which (except as otherwise  provided therein)
generally will include the following:

                   (i) to  make  deposits  to  the  Certificate  Account  in the
         amounts  and in  the  manner  provided  in the  Pooling  and  Servicing
         Agreement  and  described  above under  "Payments  on  Mortgage  Loans;
         Deposits to Certificate Account;"

                  (ii) to reimburse  itself or any Subservicer for Advances,  or
         for amounts advanced in respect of taxes, insurance premiums or similar
         expenses  ("Servicing  Advances") as to any Mortgaged Property,  out of
         late payments or collections on the Mortgage Loan with respect to which
         such Advances or Servicing Advances were made;

                  (iii) to pay to itself  or any  Subservicer  unpaid  Servicing
         Fees and Subservicing  Fees, out of payments or collections of interest
         on each Mortgage Loan;

                  (iv) 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 in respect of 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;

                  (v) to pay to itself, a Subservicer,  Residential Funding, the
         Company  or the  Seller  all  amounts  received  with  respect  to each
         Mortgage Loan purchased,  repurchased or removed  pursuant to 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;

                  (vi) to pay the  Company 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);

                  (vii) to reimburse  itself or any  Subservicer for any Advance
         previously  made which the Master  Servicer  has  determined  to not be
         ultimately recoverable from Liquidation Proceeds, Insurance Proceeds or
         otherwise (a "Nonrecoverable Advance"),  subject to any limitations set
         forth in the  Pooling  and  Servicing  Agreement  as  described  in the
         related Prospectus Supplement;

                  (viii) to  reimburse  itself or the Company for certain  other
         expenses   incurred  for  which  it  or  the  Company  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  Company  is  indemnified  pursuant  to the
         Pooling and Servicing Agreement; and

                  (ix) to withdraw any amount deposited in the Custodial Account
         that was not required to be deposited therein.


Distributions

         Beginning on the  Distribution  Date in the month next  succeeding  the
month in which the  Cut-off  Date occurs (or such 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 "Paying Agent").  Such  distributions will be made
to the persons who are  registered  as the holders of such  Certificates  at the
close of business on the last business day of the  preceding  month (the "Record
Date").  Notwithstanding any other reference herein to a Distribution Date, with
respect to a series of Certificates as to which the Trust Fund includes Mortgage
Securities,  the date on which  distributions  are to be made to the  holders of
such  Certificates  may be referred to as the "Payment Date," if so specified in
the related  Prospectus  Supplement.  Unless otherwise  specified in the related
Prospectus  Supplement,  interest which accrues and is not payable on a class of
Certificates  will be added to the principal balance of each Certificate of such
class.  Distributions  will be made in  immediately  available  funds  (by  wire
transfer or otherwise)


                                       28

<PAGE>



to  the  account  of a  Certificateholder  at a  bank  or  other  entity  having
appropriate  facilities therefor, if such  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 such 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  such
Certificates  at the office or agency of the Trustee  specified in the notice to
such Certificateholders. Distributions will be made to each Certificateholder in
accordance with such holder's  Percentage  Interest in a particular  class.  The
"Percentage Interest" represented by a Certificate of a particular class will be
equal to the percentage  obtained by dividing the initial  principal  balance or
notional amount of such Certificate by the aggregate  initial amount or notional
balance of all the Certificates of such 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  Supplement.  Distributions of interest on each class of Certificates
will be made  prior  to  distributions  of  principal  thereon.  Each  class  of
Certificates  (other  than  certain  classes of Strip  Certificates)  may have a
different  Pass-Through  Rate,  which  may be a fixed,  variable  or  adjustable
Pass-Through  Rate, or any  combination of two or more such 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 such  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 Record
Date of a class of  Certificates,  an amount  equal to the  Percentage  Interest
represented by the  Certificate  held by such holder  multiplied by such class's
Distribution  Amount. The "Distribution  Amount" for a class of Certificates for
any  Distribution  Date  will  be the  portion,  if  any,  of the  amount  to be
distributed  to such class for such  Distribution  Date in respect of principal,
plus,  if such class is entitled  to  payments of interest on such  Distribution
Date,  interest  accrued  during  the  related  interest  accrual  period at the
applicable Pass-Through Rate on the principal balance or notional amount of such
class specified in the applicable Prospectus  Supplement,  less certain interest
shortfalls,  which generally will include (i) any Deferred Interest added to the
principal balance of the Mortgage Loans and/or the outstanding balance of one or
more classes of  Certificates  on the related Due Date,  (ii) any other interest
shortfalls (including, without limitation, shortfalls resulting from application
of the Relief Act or similar  legislation  or regulations as in effect from time
to time)  allocable to  Certificateholders  which are not covered by advances or
the applicable  credit  enhancement and (iii) unless otherwise  specified in the
related  Prospectus  Supplement,  Prepayment  Interest  Shortfalls  (as  defined
herein),  in each case in such  amount  that is  allocated  to such class on the
basis set forth in the Prospectus Supplement.

         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 in respect of principal,  and any schedule or formula or
other   provisions   applicable   to  the   determination   thereof   (including
distributions  among  multiple  classes of Senior  Certificates  or  Subordinate
Certificates)  shall  be  set  forth  in  the  related  Prospectus   Supplement.
Distributions in respect of principal of any class of Certificates  will be made
on a pro rata basis among all of the Certificates of such 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 such day is not a business  day,
the next business day) of the month of distribution (the "Determination  Date"),
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  (the  information  in such  statement  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 1998:

                                           related Due Period and received or
                                           advanced by them.

       July 20............     (F)      Determination Date.

Succeeding  months  follow  the  pattern of (B)  through  (G),  except  that for
succeeding  months,  (B) will also include the first day of such month.  Certain
series of Certificates  may have different  prepayment  periods,  Cut-off Dates,
Record Dates, Due Periods, 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  such  date.  Those
     principal  payments due on or before June 1 and the  accompanying  interest
     payments,  and  any  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  payments  received in advance of the scheduled Due Date and
     not accompanied by a payment of interest for any period  following the date
     of payment  ("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  in
     respect  of such  prepaid  amounts  for the  month  in which  such  partial
     Principal Prepayments were received.

(C)  Distributions on July 27 (because July 25, 1998 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 such payments.  Funds required
     to be remitted from the  Subservicing  Accounts to the Master Servicer will
     be so  remitted on July 17  (because  July 18, 1998 is not a business  day)
     together  with any  required  Advances  by the  Subservicers  (except  that
     Principal  Prepayments  in full and certain  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 27 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 17, 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  above).
     Distributions to the holders of Senior Certificates, if any, on July 27 may
     include  certain  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  27,  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 Fund 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 such Mortgage
Securities.

Advances



         Unless otherwise  specified in the related Prospectus  Supplement,  the
Master  Servicer  will agree to  advance  (either  out of its own  funds,  funds
advanced to it by Subservicers or funds being held in the Custodial  Account for
future distribution),  for the benefit of the  Certificateholders,  on or before
each  Distribution  Date,  an amount  equal to the  aggregate  of all  scheduled
payments of  principal  (other than any Balloon  Amount in the case of a Balloon
Loan) and interest at the applicable  Pass-Through Rate or Net Mortgage Rate, as
the  case  may be (an  "Advance"),  which  were  delinquent  as of the  close of
business on the business day  preceding the  Determination  Date on the Mortgage
Loans,  but only to the extent that such 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  below  under
"--Collection and Other Servicing Practices," and no Advance will be required in
connection with any reduction in amounts  payable  pursuant to 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  Fund  includes  Mortgage  Securities,  the  Master  Servicer's
advancing obligations will be pursuant to the terms of such 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
herein.

         Advances are intended to maintain a regular flow of scheduled  interest
and  principal  payments  to related  Certificateholders.  Such  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 Certificateholders, such funds will be required to be
replaced on or before any future  Distribution  Date to the extent that funds in
the Certificate  Account on such  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
such amounts were advanced (e.g.,  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 Company,  Residential  Funding, a Subservicer or a Seller under
the circumstances  described above). Such Advances may also be reimbursable from
cash otherwise distributable to Certificateholders to the extent that the Master
Servicer  shall  determine  that  any  such  Advances  previously  made  are not
ultimately    recoverable   as   described   above.    With   respect   to   any
Senior/Subordinate  Series,  so long  as the  related  Subordinate  Certificates
remain  outstanding and subject to certain  limitations  with respect to Special
Hazard Losses,  Fraud Losses,  Bankruptcy Losses and Extraordinary  Losses, such
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 certain  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  Fund 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 such support are downgraded by a Rating
Agency rating the related  Certificates  or if any  collateral  supporting  such
obligation  is  not  performing  or is  removed  pursuant  to 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 such Mortgage  Loan, the Mortgagor pays interest on the amount prepaid
only to but not including the date on which such  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. The
shortfall  between a full month's  interest due with respect to a Mortgage  Loan
and the amount of interest paid or recovered  with respect  thereto in the event
of a  prepayment  or  liquidation  is  referred  to  as a  "Prepayment  Interest
Shortfall." 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 amount,  if
any,  necessary to assure that, on the related  Distribution Date, the Available
Distribution  Amount would  include with respect to each such  Mortgage  Loan an
amount  equal to  interest  at the  Mortgage  Rate (less the  Servicing  Fee and
Excluded Spread, if any) for such Mortgage Loan from the date of such prepayment
to the related Due Date (such amount, "Compensating Interest"). Unless otherwise
specified in the related Prospectus  Supplement,  Compensating  Interest will be
limited to the  aggregate  amount (or any portion  thereof) of the Servicing Fee
received by the Master  Servicer in that month in relation to the Mortgage Loans
or in any other manner,  and, if so limited,  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 Fund setting forth the information described in the
related  Pooling and Servicing  Agreement.  Except as otherwise  provided in the
related Pooling and Servicing Agreement, such information generally will include
the following (as applicable):

                                       31

<PAGE>




                  (i) the amount, if any, of such distribution allocable to
         principal;

                  (ii) the amount,  if any, of such  distribution  allocable  to
         interest  and the  amount,  if any, of any  shortfall  in the amount of
         interest and principal;

                  (iii) the aggregate unpaid  principal  balance of the Mortgage
         Loans after  giving  effect to the  distribution  of  principal on such
         Distribution Date;

                  (iv) the outstanding  principal  balance or notional amount of
         each class of Certificates  after giving effect to the  distribution of
         principal on such Distribution Date;

                  (v)   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;

                  (vi) the book  value of any  property  acquired  by such Trust
         Fund through foreclosure or grant of a deed in lieu of foreclosure;

                  (vii) the balance of the Reserve Fund, if any, at the close of
         business on such Distribution Date;

                  (viii) the percentage of the outstanding principal balances of
         the Senior  Certificates,  if  applicable,  after giving  effect to the
         distributions on such Distribution Date;

                  (ix) 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;

                  (x) 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 such amounts;

                  (xi) in the case of Certificates  benefiting from  alternative
         credit enhancement  arrangements  described in a Prospectus Supplement,
         the amount of coverage under such  alternative  arrangements  as of the
         close of business on the applicable Determination Date;

                  (xii) the servicing fee payable to the Master Servicer and the
         Subservicer; and

                  (xiii) with respect to any series of  Certificates as to which
         the  Trust  Fund  includes  Mortgage  Securities,   certain  additional
         information  as  required  under  the  related  Pooling  and  Servicing
         Agreement.

         Each  amount  set forth  pursuant  to clause  (i) or (ii) above will be
expressed as a dollar amount per Single Certificate. As to a particular class of
Certificates,  a "Single  Certificate"  generally  will  evidence  a  Percentage
Interest  obtained  by  dividing  $1,000 by the  initial  principal  balance  or
notional  balance of all the  Certificates  of such class,  except as  otherwise
provided in the  related  Pooling and  Servicing  Agreement.  In addition to the
information  described above,  reports to  Certificateholders  will contain such
other  information  as is set  forth 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 Fund.

         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 such calendar
year.  Such report  will  include  information  as to the  aggregate  of amounts
reported  pursuant to clauses (i) and (ii) above for such  calendar  year or, in
the event such person was a holder of record of a class of Certificates during a
portion of such calendar year, for the applicable portion of such 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 such  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 such 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 such
waiver or  modification  is not  materially  adverse to any  Certificateholders,
taking into account any estimated loss that may result absent such action.  With
respect  to any  series of  Certificates  as to which the  Trust  Fund  includes
Mortgage   Securities,   the  Master  Servicer's  servicing  and  administration
obligations will be pursuant to the terms of such Mortgage Securities.



                                       32

<PAGE>



         Under its  Subservicing  Agreement,  a Subservicer  is granted  certain
discretion to extend relief to Mortgagors  whose payments become  delinquent.  A
Subservicer  may grant a period of temporary  indulgence  (generally 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  approval of the Master
Servicer. Other types of forbearance generally 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  certain  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  certain  modifications  of the Mortgage Loan rather than  proceeding
with foreclosure. In making such determination, the estimated Realized Loss that
might result if such Mortgage Loan were liquidated  would be taken into account.
Such  modifications  may  have the  effect  of  reducing  the  Mortgage  Rate or
extending  the final  maturity  date of the  Mortgage  Loan.  Any such  modified
Mortgage  Loan may  remain in the  related  Trust  Fund,  and the  reduction  in
collections resulting from such 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  such that the monthly  payment is  recalculated  as an amount that
will fully  amortize  the  remaining  principal  amount  thereof by the original
maturity  date  based  on  the  original  Mortgage  Rate,   provided  that  such
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 such  conveyance,  to  exercise  its rights to
accelerate  the  maturity of such  Mortgage  Loan under any  due-on-sale  clause
applicable  thereto,  but only if the  exercise of such 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  such  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 such
due-on-sale  clause,  the  Master  Servicer  or  Subservicer  will enter into an
assumption and modification  agreement with the person to whom such property has
been or is about to be conveyed,  pursuant to which such person  becomes  liable
under the Mortgage Note subject to certain  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 such release
will not adversely affect the  collectability  of the Mortgage Loan. An ARM Loan
may be  assumed  if such  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 such ARM  Loan  would  not be  impaired  by the
assumption.  If a Mortgagor  transfers the Mortgaged  Property subject to an ARM
Loan without  consent,  such 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--Enforceability of Certain Provisions" herein. 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 such
a 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 such 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 such 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.


Realization Upon Defaulted Mortgage Loans

         In the event  that  title to any  Mortgaged  Property  is  acquired  in
foreclosure or by deed in lieu of  foreclosure,  the deed or certificate of sale
will be issued to the Trustee or to its nominee on behalf of Certificateholders.
Notwithstanding  any such  acquisition of title and  cancellation of the related
Mortgage  Loan,  such Mortgage Loan (an "REO Mortgage  Loan") will be considered
for most  purposes  to be an  outstanding  Mortgage  Loan held in the Trust Fund
until  such  time  as  the  Mortgaged  Property  is  sold  and  all  recoverable
Liquidation  Proceeds and Insurance  Proceeds have been received with respect to
such defaulted  Mortgage Loan (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 such
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,
such  amortization  schedule will be deemed to have adjusted in accordance  with
any interest rate changes  occurring on any adjustment date therefor) so long as
such REO Mortgage  Loan is  considered  to remain in the Trust Fund.  If a REMIC
election has been made, any Mortgaged


                                       33

<PAGE>



Property so acquired  by the Trust Fund must be disposed of in  accordance  with
applicable  federal income tax regulations and consistent with the status of the
Trust  Fund as a REMIC.  To the  extent  provided  in the  related  Pooling  and
Servicing Agreement,  any income (net of expenses and other than gains described
below)  received by the  Subservicer  or the Master  Servicer on such  Mortgaged
Property  prior to its  disposition  will be deposited in the Custodial  Account
upon receipt and will be  available  at such 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 such remedies if it determines  that one
such remedy is more  likely to result in a greater  recovery.  If such  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 such 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, such Mortgage Loan will be removed from the related
Trust Fund. The Master Servicer may 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 such 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 such 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 such defaulted Mortgage Loan.

         With respect to certain series of  Certificates,  if so provided in the
related  Prospectus  Supplement,  the applicable form of credit  enhancement may
provide, to the extent of coverage thereunder, that a defaulted Mortgage Loan or
REO  Mortgage  Loan  will be  removed  from the  Trust  Fund  prior to the final
liquidation  thereof.  Unless  otherwise  specified  in the  related  Prospectus
Supplement,  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 such  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 such 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 such class.  In the event that
any such class of  Certificates  to which such Realized Loss was allocated is no
longer outstanding, such subsequent recovery shall be distributed to the persons
who were the holders of such 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  subject to certain  conditions in the
event that,  following the final liquidation of a Mortgage Loan and a draw under
such credit  enhancement,  subsequent  recoveries  are received.  If a defaulted
Mortgage Loan or REO Mortgage Loan is not so removed from the Trust Fund,  then,
upon the final liquidation  thereof,  if a loss is realized which is not covered
by  any  applicable  form  of  credit   enhancement  or  other  insurance,   the
Certificateholders  will bear such 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  such  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,  certain 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  such amount among the various  classes of  Certificates  included in
such series, will be described in the related Prospectus Supplement.  Generally,
with respect to any such series,  the amount available for distribution  will be
allocated first to interest on the Senior  Certificates of such 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.

         With respect to any defaulted Mortgage Loan that is finally liquidated,
the amount of loss  realized,  if any (as  described in the related  Pooling and
Servicing  Agreement,  a "Realized Loss"),  will equal the portion of the Stated
Principal  Balance  remaining after application of all amounts recovered (net of
amounts  reimbursable to the Master Servicer for related  Advances and expenses)
towards  interest and principal  owing on the Mortgage  Loan.  With respect to a
Mortgage Loan the principal balance of which has been reduced in connection with
bankruptcy  proceedings,  the  amount of such  reduction  will be  treated  as a
Realized  Loss.  The "Stated  Principal  Balance" of any Mortgage Loan as of any
date of  determination  is  equal to the  principal  balance  thereof  as of the
Cut-off Date, after  application of all scheduled  principal  payments due on or
before the  Cut-off  Date,  whether  received  or not,  reduced  by all  amounts
allocable to principal that are distributed to  Certificateholders  on or before
the  date of  determination,  and as  further  reduced  to the  extent  that any
Realized Loss thereon has been allocated to any  Certificates  on or before such
date.

         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.  Unless  otherwise  specified in the related
Prospectus  Supplement,  any Realized Loss  subsequently  incurred in connection
with any such Mortgage Loan will be borne by the then-current Certificateholders
of the class or  classes  that  would  have  borne  such  Realized  Loss if such
Mortgage Loan had not been so purchased.

         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 the outstanding  principal
balances thereof have been reduced to zero.  Additional Realized Losses, if any,
will be allocated to the Senior Certificates.  If such series includes more than
one  class of Senior  Certificates,  such  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.

         With respect to certain  Realized Losses resulting from physical damage
to  Mortgaged  Properties  which are  generally  of the same type as are covered
under a  Special  Hazard  Insurance  Policy,  the  amount  thereof  that  may be
allocated to the  Subordinate  Certificates of the related series may be limited
to an amount (the "Special Hazard Amount")  specified in the related  Prospectus
Supplement.  See  "Description of Credit  Enhancement--Special  Hazard Insurance
Policies."  If so, any 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 an amount  (with  respect  to Fraud
Losses,  the "Fraud Loss  Amount" and with  respect to  Bankruptcy  Losses,  the
"Bankruptcy Amount"),  and the Subordinate  Certificates may provide no coverage
with respect to certain  other  specified  types of losses,  as described in the
related Prospectus Supplement, in which case such 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 set forth in the related  Prospectus  Supplement,
that the then-current  rating of the related series of Certificates  will not be
adversely affected thereby.

         Generally,  any  allocation  of a Realized  Loss  (including  a Special
Hazard Loss) to a  Certificate  in a  Senior/Subordinate  Series will be made by
reducing the outstanding  principal  balance thereof as of the Distribution Date
following the calendar month in which such Realized Loss was incurred.



                                       35

<PAGE>



         As set forth  above,  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 such class
(or, if applicable,  the related  notional  amount).  The outstanding  principal
balance of any Certificate will be reduced by all amounts previously distributed
on  such  Certificate  in  respect  of  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 set forth in the  related  Prospectus  Supplement,  holders of Senior
Certificates  may be entitled to receive a  disproportionately  larger amount of
prepayments  received  during  certain  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 Fund (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,  as set
forth above,  certain  Realized  Losses  generally  will be  allocated  first to
Subordinate  Certificates  by reduction  of the  outstanding  principal  balance
thereof,  which  will have the effect of  increasing  the  respective  ownership
interest evidenced by the Senior Certificates in the related Trust Fund.

         If so provided in the related  Prospectus  Supplement,  certain 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 any or a specified portion of distributions with respect to the Mortgage
Loans may be  subordinated  to the extent of the amount set forth in the related
Prospectus  Supplement (the "Subordinate  Amount").  As specified in the related
Prospectus Supplement,  the Subordinate Amount may be subject to reduction based
upon the amount of losses borne by the holders of the  Subordinate  Certificates
as a result of such subordination,  a specified schedule or such other method of
reduction as such Prospectus Supplement may specify.

         With respect to any Senior/Subordinate Series, the terms and provisions
of the subordination may vary from those described above. Any such 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
(i) attributable to the Mortgagor's  failure to make any payment of principal or
interest as required under the Mortgage  Note, but not including  Special Hazard
Losses,  Extraordinary  Losses  or  other  losses  resulting  from  damage  to a
Mortgaged  Property,  Bankruptcy  Losses  or  Fraud  Losses  (any  such  losses,
"Defaulted  Mortgage  Losses");  (ii) of a type  generally  covered by a Special
Hazard  Insurance  Policy (any such  losses,  "Special  Hazard  Losses");  (iii)
attributable  to certain  actions  which may be taken by a  bankruptcy  court in
connection with a Mortgage Loan,  including a reduction by a bankruptcy court of
the principal balance of or the Mortgage Rate on a Mortgage Loan or an extension
of its maturity  (any such losses,  "Bankruptcy  Losses");  and (iv) incurred on
defaulted  Mortgage Loans as to which there was fraud in the origination of such
Mortgage Loans (any such losses, "Fraud Losses").  Unless otherwise specified in
the related  Prospectus  Supplement,  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  losses  occasioned  by war,  civil
insurrection,  certain governmental actions,  nuclear reaction and certain other
risks  ("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  specified  in  the   applicable   Prospectus   Supplement,   credit
enhancement  may be in the form of a Reserve Fund to cover such  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,  certain other secured or unsecured corporate  guarantees or
in such 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  certain
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.  In addition,  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 Bond
and  coverage  with  respect  to Fraud  Losses  may be  provided  by a  mortgage
repurchase bond. Certain coverage may also be provided by  representations  made
by Residential Funding or the Company. 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  Loan-to-  Value Ratios at
origination of over 80% which are not insured by a Primary  Insurance Policy, to
the extent that such 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 certain other forms described in this section. Credit
support may also be provided in the form of an  insurance  policy  covering  the
risk of  collection  and  adequacy  of any  Additional  Collateral  provided  in
connection with any Additional  Collateral Loan,  subject to the limitations set
forth in any such  insurance  policy.  As set forth in the Pooling and Servicing
Agreement,  credit  support may apply to all of the Mortgage Loans or to certain
Mortgage Loans contained in a Mortgage Pool.

         Each Prospectus Supplement will include a description of (a) the amount
payable under the credit enhancement arrangement,  if any, provided with respect
to a series,  (b) any conditions to payment  thereunder not otherwise  described
herein,  (c) the  conditions  under which the amount  payable  under such credit
support may be reduced and under which such credit  support may be terminated or
replaced  and (d) the  material  provisions  of any  agreement  relating to such
credit support. Additionally,  each Prospectus Supplement will set forth certain
information  with respect to the issuer of any  third-party  credit  enhancement
(the "Credit Enhancer"),  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  Prospectus  Supplement and the 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 such policies,  copies of which  generally will
be exhibits to the Form 8-K to be filed with the  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 (the  "Letter of  Credit"),  a bank (the
"Letter of Credit  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


                                       37

<PAGE>



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 certain 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 (each,
a "Mortgage  Pool  Insurance  Policy")  obtained by the Company for a Trust Fund
will be issued by the Pool Insurer. Each Mortgage Pool Insurance Policy, subject
to the  limitations  described below 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  set  forth  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
certain conditions  precedent  described below.  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.

         Each Mortgage Pool Insurance  Policy will provide that no claims may be
validly  presented  thereunder  unless,  among other  things,  (i) any  required
Primary  Insurance  Policy is in effect for the  defaulted  Mortgage  Loan and a
claim  thereunder has been submitted and settled,  (ii) hazard  insurance on the
property  securing  such  Mortgage  Loan has been kept in force and real  estate
taxes and  other  protection  and  preservation  expenses  have been paid by the
Master  Servicer,  (iii)  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 (iv) the insured has acquired  good and
merchantable  title to the  Mortgaged  Property  free and clear of liens  except
certain permitted encumbrances.  Upon satisfaction of these conditions, the Pool
Insurer will have the option  either (a) to purchase  the property  securing the
defaulted  Mortgage Loan at a price equal to the outstanding  principal  balance
thereof plus accrued and unpaid interest at the applicable  Mortgage Rate to the
date of  purchase  and  certain  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
certain  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 such 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 such 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  such  policies),  from  the  related  hazard  insurance  policy  or
applicable  Special Hazard  Instrument 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) such 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) such expenses will be recoverable by it through Liquidation
Proceeds or Insurance Proceeds.

         Unless  otherwise  specified in the related  Prospectus  Supplement,  a
Mortgage Pool Insurance  Policy (and certain  Primary  Insurance  Policies) will
likely not insure  against loss  sustained by reason of a default  arising from,
among other things, (i) fraud or negligence in the origination or servicing of a
Mortgage Loan, including misrepresentation by the Mortgagor, the Seller or other
persons  involved  in the  origination  thereof,  (ii)  failure to  construct  a
Mortgaged  Property  in  accordance  with  plans  and  specifications  or  (iii)
bankruptcy,  except  if  specified  in  the  related  Prospectus  Supplement  an
endorsement to the Mortgage Pool Insurance Policy provides for insurance against
any  such  loss.   Depending   upon  the  nature  of  the  event,  a  breach  of
representation  made by a Seller may also have  occurred.  Such a 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 Company or Residential Funding.

         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 certain 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 and
Related  Matters--Foreclosure."  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 exhausted  and any further
losses will be borne by the related Certificateholders.  In addition, unless the
Master Servicer determines that an


                                       38

<PAGE>



Advance in respect of a delinquent Mortgage Loan would be recoverable to it from
the proceeds of the  liquidation of such Mortgage Loan or otherwise,  the Master
Servicer  would  not be  obligated  to  make  an  Advance  respecting  any  such
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,  such policy will not
provide coverage against hazard losses.  As set forth 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 such losses. Additionally, no coverage in respect of 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 (a "Special Hazard
Insurance Policy") obtained for a Trust Fund will be issued by the insurer named
in the related  Prospectus  Supplement  (the  "Special  Hazard  Insurer").  Each
Special Hazard  Insurance  Policy subject to limitations  described below and in
the  related   Prospectus   Supplement,   if  any,   will  protect  the  related
Certificateholders from Special Hazard Losses which are (i) losses due to direct
physical damage to a Mortgaged Property other than any loss of a type covered by
a hazard insurance policy or a flood insurance policy,  if applicable,  and (ii)
losses  from  partial  damage  caused  by  reason  of  the  application  of  the
co-insurance  clauses  contained in hazard  insurance  policies.  See "Insurance
Policies on Mortgage  Loans." A Special Hazard  Insurance  Policy will not cover
losses  occasioned by war, civil  insurrection,  certain  governmental  actions,
errors  in  design,  faulty  workmanship  or  materials  (except  under  certain
circumstances),  nuclear  reaction,  chemical  contamination  or  waste  by  the
Mortgagor.  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 set forth in such  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.

         Subject to 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  such  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 such  property  or (ii) upon  transfer  of the  property  to the
insurer,  the  unpaid  principal  balance of such  Mortgage  Loan at the time of
acquisition of such 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 such  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 certain expenses is paid by the Special Hazard Insurer,  the amount
of further  coverage under the related Special Hazard  Insurance  Policy will be
reduced by such 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 such 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 such policy may be validly
presented with respect to the defaulted  Mortgage Loan secured by such property.
The payment  described  under (ii) above will render  presentation of a claim in
respect of such 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  certain  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.


Bankruptcy Bonds

     In the event of a personal  bankruptcy of a Mortgagor,  a bankruptcy  court
may  establish the value of the Mortgaged  Property of such  Mortgagor  (and, if
specified  in  the  related  Prospectus   Supplement,   any  related  Additional
Collateral) at an amount less than the then outstanding principal balance of the
Mortgage Loan secured by such Mortgaged Property (such difference,  a "Deficient
Valuation"). The amount of the secured debt could then be reduced to such value,
and, thus,  the holder of such Mortgage Loan would become an unsecured  creditor
to the extent the  outstanding  principal  balance of such Mortgage Loan exceeds
the  value  assigned  to the  Mortgaged  Property  (and any  related  Additional
Collateral) by the bankruptcy court. In addition, certain other modifications of
the terms of a Mortgage Loan can result from a bankruptcy proceeding,  including
a reduction in the amount of the Monthly  Payment on the related  Mortgage Loan,
but not any permanent forgiveness of principal (a "Debt Service Reduction"). See
"Certain Legal Aspects of Mortgage Loans--Anti-Deficiency  Legislation and Other
Limitations on Lenders." Any Bankruptcy Bond to provide  coverage for Bankruptcy
Losses resulting from proceedings under the federal Bankruptcy Code obtained for
a Trust  Fund will be  issued  by an  insurer  named in the  related  Prospectus
Supplement.  The level of coverage under each  Bankruptcy Bond will be set forth
in the related Prospectus Supplement.

Reserve Funds

         If so specified in the related Prospectus Supplement,  the Company will
deposit  or  cause  to be  deposited  in  an  account  (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 such
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  such  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 certain  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 such Reserve Fund will not
be deemed to be part of the  related  Trust  Fund.  A Reserve  Fund may  provide
coverage  to more than one series of  Certificates,  if set forth in the related
Prospectus Supplement.

         Unless otherwise  specified 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.  However,  to the extent
that the Company,  any affiliate  thereof or any other entity has an interest in
any Reserve Fund, in the event of the bankruptcy,  receivership or insolvency of
such entity,  there could be delays in withdrawals from the Reserve Fund and the
corresponding  payments to the  Certificateholders.  Such 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 Company may
obtain  one  or  more  certificate  insurance  policies  (each,  a  "Certificate
Insurance  Policy") or guaranties  or one or more surety bonds (each,  a "Surety
Bond"),  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 such class or classes of
Certificates.  Any Certificate  Insurance  Policy,  Surety Bond or guaranty will
have the  characteristics  described in, and will be subject to such limitations
and exceptions set forth 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  such  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.

         In the event the related  insurer  ceases to be a  "Qualified  Insurer"
because  it  ceases  to be  qualified  under  applicable  law to  transact  such
insurance  business  or  coverage  is  terminated  for  any  reason  other  than
exhaustion of such coverage,  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
such policy.  If the cost of the replacement  policy is greater than the cost of
such policy,  the coverage of the  replacement  policy  will,  unless  otherwise
agreed to by the Company,  be reduced to a level such 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 ("Freddie Mac"), the
Federal National  Mortgage  Association  ("Fannie Mae") or any successor entity,
the Master  Servicer  will review,  not less often than  monthly,  the financial
condition of such 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,  subject to 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.



                                       40

<PAGE>



         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 such  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 such 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 such determinations  incorrectly or recovery is
not  available  for any  other  reason,  the  Master  Servicer  is  nevertheless
obligated  to follow  such  normal  practices  and  procedures  (subject  to the
preceding  sentence)  as it deems  necessary  or  advisable  to realize upon the
defaulted Mortgage Loan and in the event such determination has been incorrectly
made,  is entitled to  reimbursement  of its  expenses in  connection  with such
restoration.


Reduction or Substitution of Credit Enhancement

         Unless otherwise specified in the Prospectus Supplement,  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  certain  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,  such 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 Company 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 such credit  support with other credit  enhancement
instruments  issued by obligors  whose  credit  ratings are  equivalent  to such
downgraded level and in lower amounts which would satisfy such 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  Company,
the Master Servicer or such 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 (collectively,  "Swaps"), and other yield
supplement  agreements or similar  yield  maintenance  arrangements  that do not
involve swap  agreements or other notional  principal  contracts  (collectively,
"Yield Supplement Agreements").

         An   interest   rate  Swap  is  an   agreement   between   two  parties
("Counterparties")  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
such as the London  Interbank  Offered Rate ("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
prinicpals 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 certain  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 Fund to do so.

Purchase Obligations



                                       41

<PAGE>



         Certain types of Mortgage Loans and certain  classes of Certificates of
any series, as specified in the related Prospectus Supplement, may be subject to
a purchase obligation (a "Purchase  Obligation") that would become applicable on
one or more  specified  dates,  or upon the  ocurrence of one or more  specified
events, or on demand made by or on behalf of the applicable  Certificateholders.
A  Purchase  Obligation  may be in the form of a  conditional  or  unconditional
purchase  commitment,   liquidity  facility,   remarketing  agreement,  maturity
guaranty,  put  option or demand  feature.  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 the provider thereof,  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
such obligation relate.

                      INSURANCE POLICIES ON MORTGAGE LOANS

         Each Mortgage Loan will be required to be covered by a hazard insurance
policy (as described below) and, in certain cases, a Primary Insurance Policy or
an alternative  form of coverage,  as described  below.  The descriptions of any
insurance policies set forth 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 such forms of policies.

Primary Mortgage Insurance Policies

         Unless otherwise  specified in the related Prospectus  Supplement,  (i)
each  Mortgage  Loan having a  Loan-to-Value  Ratio at  origination  of over 80%
generally will be covered by a primary  mortgage  guaranty  insurance  policy (a
"Primary Insurance Policy") insuring against default on such 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
a  Loan-to-Value  Ratio  equal to or less than 80%,  and (ii) the  Company  will
represent  and  warrant  that,  to the  best of the  Company's  knowledge,  such
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  herein 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 Loan-to-Value  Ratio level
as of the applicable Cut-off Date. Unless otherwise  specified in the Prospectus
Supplement,  the Company  will have the ability to cancel any Primary  Insurance
Policy if the Loan-to-Value 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 such Closing Date.
Mortgage Loans which are subject to negative  amortization  will only be covered
by a Primary  Insurance  Policy if such  coverage  was so  required  upon  their
origination,  notwithstanding  that subsequent  negative  amortization may cause
such Mortgage Loan's Loan-to-Value Ratio (based on the then-current  balance) to
subsequently  exceed the limits which would have  required  such  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 (a "Primary  Insurer")  will differ
generally  from  those in Primary  Insurance  Policies  issued by other  Primary
Insurers,  each Primary  Insurance  Policy  generally  will pay either:  (i) the
insured  percentage  of the loss on the  related  Mortgaged  Property;  (ii) the
entire  amount of such loss,  after  receipt by the Primary  Insurer of good and
merchantable  title to, and possession of, the Mortgaged  Property;  or (iii) 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 generally consist of the
unpaid  principal  amount of such Mortgage Loan and accrued and unpaid  interest
thereon and reimbursement of certain expenses,  less (i) rents or other payments
received by the insured (other than the proceeds of hazard  insurance)  that are
derived from the related  Mortgaged  Property,  (ii) hazard  insurance  proceeds
received  by the  insured  in excess of the  amount  required  to  restore  such
Mortgaged  Property  and  which  have not been  applied  to the  payment  of the
Mortgage Loan,  (iii) amounts  expended but not approved by the Primary Insurer,
(iv)  claim  payments  previously  made on such  Mortgage  Loan  and (v)  unpaid
premiums and certain 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: (i) 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;  (ii) 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  (iii)  tender  to  the  Primary  Insurer  good  and
merchantable title to, and possession of, the Mortgaged Property.



                                       42

<PAGE>



         For any  Certificates  offered  hereunder,  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 such  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 such Primary Insurance Policy was in place
as of the Cut-off Date and the Company had  knowledge of such Primary  Insurance
Policy.  In the event that the Company  gains  knowledge  that as of the Closing
Date, a Mortgage Loan had a Loan-to-Value  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 such  standard or covered by alternate  credit  enhancement  as
described in the related Prospectus  Supplement) and that such Mortgage Loan has
a then current Loan-to-Value 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 such 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.  Such coverage  generally  will be in an
amount equal to the lesser of the  principal  balance of such  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 such 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.

         In general,  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,  subject to 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.  Such  policies
typically do not cover any physical  damage  resulting from the following:  war,
revolution,  governmental actions,  floods and other water-related causes, earth
movement (including  earthquakes,  landslides and mudflows),  nuclear reactions,
wet or dry rot,  vermin,  rodents,  insects or domestic  animals,  theft and, in
certain cases,  vandalism.  The foregoing  list is merely  indicative of certain
kinds of  uninsured  risks and is not  intended to be  all-inclusive.  Where the
improvements  securing a Mortgage  Loan are  located in a  federally  designated
flood area at the time of  origination  of such 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 in general 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 which in effect requires the insured at
all times to carry insurance of a specified percentage (generally 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  insured's  coverage  falls
below  this  specified  percentage,  such  clause  generally  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) such  proportion  of the loss as the  amount of  insurance
carried bears to the specified  percentage of the full  replacement cost of such
improvements.

         Since the amount of hazard  insurance  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  such  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 COMPANY

         The Company is an indirect  wholly-owned  subsidiary of GMAC  Mortgage,
which is a wholly-owned subsidiary of General Motors Acceptance Corporation. The
Company was  incorporated  in the State of Delaware  on January  25,  1985.  The
Company was organized for the purpose of serving as a private secondary mortgage
market conduit. The Company anticipates that it will in many cases have acquired
Mortgage Loans indirectly through Residential Funding, which is also an indirect
wholly-owned  subsidiary of GMAC Mortgage.  The Company 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  Company.  The  Company's  only  obligations  with  respect  to a series  of
Certificates will be pursuant to certain limited  representations and warranties
made  by  the  Company  or as  otherwise  provided  in  the  related  Prospectus
Supplement.


                                       43

<PAGE>




         The Company  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,  an  affiliate  of the  Company,  will  act as the  Master
Servicer or Manager for a series of Certificates.

         Residential Funding 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'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 conducts operations from its headquarters in
Minneapolis and from offices located in California,  New York, Florida,  Georgia
and Maryland.

         Residential Funding's delinquency, foreclosure and loan loss experience
as of the end of the most recent calendar  quarter for which such information is
available on the portfolio of loans master  serviced by it that were  originated
under its modified loan purchase  criteria will be summarized in each Prospectus
Supplement  relating to a Mortgage  Pool master  serviced by it. There can be no
assurance that such 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 above under  "Description  of the  Certificates--General,"
each series of  Certificates  will be issued pursuant to a Pooling and Servicing
Agreement as described in that section. The following summaries describe certain
additional provisions common to each Pooling and Servicing Agreement.


Servicing and Other Compensation and Payment of Expenses

         The principal servicing  compensation to be paid to the Master Servicer
in respect of its master  servicing  activities for each series of  Certificates
will be equal to the  percentage per annum  described in the related  Prospectus
Supplement  (which  may vary under  certain  circumstances)  of the  outstanding
principal  balance of each Mortgage Loan, and such compensation will be retained
by it from  collections  of interest on such  Mortgage Loan in the related Trust
Fund  (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  such  collections  are  deposited  into the  applicable  Custodial
Account. Notwithstanding the foregoing, with respect to a series of Certificates
as to which  the Trust  Fund  includes  Mortgage  Securities,  the  compensation
payable to the Master Servicer or Manager for servicing and  administering  such
Mortgage  Securities on behalf of the holders of such  Certificates may be based
on a percentage per annum described in the related Prospectus  Supplement of the
outstanding  balance  of  such  Mortgage  Securities  and may be  retained  from
distributions  of interest  thereon,  if so specified in the related  Prospectus
Supplement.  Unless otherwise 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.  Certain
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  Company  or
Residential  Funding,  as the case may be,  committed  to purchase  the Mortgage
Loan. See "Mortgage Loan Program--Subservicing by Sellers." 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.  Unless  otherwise  specified  in the related  Prospectus
Supplement, the Master Servicer will retain such 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 as a result of the
investment  of funds in the  Custodial  Account  or the  applicable  Certificate
Account (unless otherwise specified in the related Prospectus  Supplement) or in
a  Subservicing  Account,  as the case may be. In addition,  certain  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  certain  ongoing
expenses  associated  with each Trust Fund 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 in respect of 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 certain limited circumstances. In addition, as
indicated in the  preceding  section,  the Master  Servicer  will be entitled to
reimbursements for certain 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 (i) 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 such Pooling and Servicing  Agreement has been made under
the supervision of such officer,  (ii) to the best of such officer's  knowledge,
based on such 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 such
Pooling and  Servicing  Agreement  throughout  such year,  or, if there has been
material  noncompliance  with such servicing  standards or a material default in
the  fulfillment  of  any  such  obligation,  such  statement  shall  include  a
description  of such  noncompliance  or specify each such default  known to such
officer  and the  nature  and  status  thereof  and  (iii)  to the  best of such
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 such year,
or, if there has been material  noncompliance with such servicing standards or a
material  default in the fulfillment of such  obligations,  such statement shall
include a description of such noncompliance or specify each such default, as the
case may be,  known to such  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 such 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  such  exceptions  and  other
qualifications  that,  in the opinion of such firm,  such  accounting  standards
require it to report.  In rendering  such  statement,  such 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 Company

         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 such duties is
no longer  permissible  under  applicable  law or except  in  connection  with a
permitted transfer of servicing. No such 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
set forth below,  neither the Master  Servicer,  the Company,  nor any director,
officer,  employee or agent of the Master  Servicer or the Company will be under
any liability to the Trust Fund or the  Certificateholders  for any action taken
or for  refraining  from the taking of any action in good faith  pursuant to the
Pooling and Servicing Agreement, or for errors in judgment;  provided,  however,
that  neither  the Master  Servicer,  the  Company,  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 Company, and any director, officer, employee or agent of the Master Servicer
or the Company is entitled to indemnification by the Trust Fund 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 pursuant to 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 Company 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
Company may, however,  in its discretion  undertake any such 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 such event,  the legal expenses and costs of
such action and any liability  resulting  therefrom will be expenses,  costs and
liabilities  of the Trust Fund and the Master  Servicer or the  Company,  as the
case may be, will be entitled to be reimbursed  therefor 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) such person is qualified to service
mortgage  loans on behalf of Fannie  Mae or  Freddie  Mac and (ii) such  merger,
consolidation or succession does not adversely affect the then-current rating of
the  classes of  Certificates  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 such person is reasonably  satisfactory  to the Company and the Trustee.  In
the case of any such assignment, the


                                       45

<PAGE>



Master  Servicer  will be released from its  obligations  under such Pooling and
Servicing  Agreement,  exclusive of liabilities and  obligations  incurred by it
prior to the time of such assignment.


Events of Default

         Events of Default under the Pooling and Servicing  Agreement in respect
of a series  of  Certificates,  unless  otherwise  specified  in the  Prospectus
Supplement,  will  include,  without  limitation,  (i) 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 such series any required payment which continues  unremedied for
five days  after the  giving of  written  notice of such  failure  to the Master
Servicer by the Trustee or the Company,  or to the Master Servicer,  the Company
and the Trustee by the holders of Certificates of such class evidencing not less
than 25% of the aggregate Percentage Interests constituting such class; (ii) 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 such series of Certificates which continues unremedied
for 30  days  (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 such failure to the
Master Servicer by the Trustee or the Company,  or to the Master  Servicer,  the
Company  and the  Trustee by the  holders of any class of  Certificates  of such
series  evidencing  not less  than  25% of the  aggregate  Percentage  Interests
constituting such class; and (iii) certain 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 pursuant to the terms
of any Mortgage  Securities  included in any Trust Fund 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 Company
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
Fund (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  Company 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  such  Trust  Fund  and in and to the
Mortgage Loans and the proceeds  thereof,  whereupon the Trustee or, upon notice
to the Company and with the Company's consent,  its designee will succeed to all
responsibilities,  duties  and  liabilities  of the Master  Servicer  under such
Pooling and Servicing  Agreement (other than the obligation to purchase Mortgage
Loans under certain  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 such  appointment,  the
Trustee is obligated to act in such 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 such Pooling and Servicing
Agreement (except as otherwise provided for in the related Pooling and Servicing
Agreement with respect to the Credit Enhancer) unless such 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  such class have made written
request upon the Trustee to institute such proceeding in its own name as Trustee
thereunder and have offered to the Trustee reasonable  indemnity and the Trustee
for 60 days after receipt of such request and indemnity has neglected or refused
to  institute  any  such  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 such Pooling and  Servicing  Agreement,
unless such  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 Company, the
Master   Servicer  and  the   Trustee,   without  the  consent  of  the  related
Certificateholders (i) to cure any ambiguity;  (ii) to correct or supplement any
provision  therein which may be inconsistent with any other provision therein or
to correct any error;  (iii) 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) such
change may not  adversely  affect in any material  respect the  interests of any
Certificateholder,  as evidenced  by an opinion of counsel,  and (c) such 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;  (iv) if a REMIC  election has
been made with respect to the related Trust Fund, to modify, eliminate or add to
any of its provisions (a) to the extent necessary to maintain the  qualification
of the Trust Fund as a REMIC or to avoid or minimize the risk of  imposition  of
any tax on the


                                       46

<PAGE>



related Trust Fund, provided that the Trustee has received an opinion of counsel
to the effect that (1) such action is necessary  or  desirable to maintain  such
qualification  or to avoid or minimize  such risk,  and (2) such action will not
adversely  affect in any material respect the interests of any, or (b) to modify
the provisions regarding the transferability of the REMIC Residual Certificates,
provided  that the Company has  determined  that such 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;  (v) to make any other  provisions  with  respect  to
matters or questions  arising under such Pooling and Servicing  Agreement  which
are not materially  inconsistent  with the provisions  thereof,  so long as such
action will not  adversely  affect in any material  respect the interests of any
Certificateholder,  or (vi) to amend specified  provisions that are not material
to holders of any class of Certificates offered hereunder.

         The Pooling and Servicing Agreement may also be amended by the Company,
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 such class for the purpose of adding any provisions to or
changing in any manner or eliminating  any of the provisions of such 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 such  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 such  class have  consented  to the
change in such percentage.

         Notwithstanding  the foregoing,  if a REMIC election has been made with
respect to the related  Trust Fund,  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 such amendment or the exercise
of any power  granted  to the Master  Servicer,  the  Company or the  Trustee in
accordance with such amendment will not result in the imposition of a tax on the
related Trust Fund or cause such Trust Fund to fail to qualify as a REMIC.


Termination; Retirement of Certificates

         The obligations created by the Pooling and Servicing Agreement for each
series  of   Certificates   (other  than  certain  limited  payment  and  notice
obligations  of the Trustee and the Company,  respectively)  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 such
Certificateholders  following  the  earlier  of (i) 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 (ii) the purchase by the Master
Servicer or the Company or, if specified in the related  Prospectus  Supplement,
by the holder of the REMIC Residual  Certificates  (see "Certain  Federal Income
Tax  Consequences"  below) from the Trust Fund for such series of all  remaining
Mortgage Loans and all property  acquired in respect of such Mortgage  Loans. In
addition  to the  foregoing,  the Master  Servicer  or the  Company may have the
option to purchase, in whole but not in part, the Certificates  specified in the
related Prospectus  Supplement in the manner set forth 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  Company,  the  Mortgage  Loans may be
sold,  thereby effecting a retirement of the Certificates and the termination of
the Trust Fund,  or the  Certificates  so purchased may be held or resold by the
Master Servicer or the Company. 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 such termination.

         Any such purchase of Mortgage Loans and property acquired in respect of
Mortgage Loans evidenced by a series of Certificates shall be made at the option
of the Master Servicer,  the Company or, if applicable,  the holder of the REMIC
Residual   Certificates  at  the  price  specified  in  the  related  Prospectus
Supplement.  The  exercise of such right will  effect  early  retirement  of the
Certificates  of that  series,  but the right of any such entity to purchase the
Mortgage Loans and related property will be subject to the criteria, and will be
at the  price,  set  forth in the  related  Prospectus  Supplement.  Such  early
termination may adversely affect the yield to holders of certain classes of such
Certificates.  If a REMIC election has been made, the termination of the related
Trust Fund will be  effected  in a manner  consistent  with  applicable  federal
income tax regulations and its status as a REMIC.


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 Company  and/or its
affiliates, including Residential Funding.

         The Trustee may resign at any time,  in which event the Company will be
obligated  to appoint a  successor  trustee.  The  Company  may also  remove the
Trustee if the  Trustee  ceases to be  eligible  to  continue  as such under the
Pooling and  Servicing  Agreement  or if the  Trustee  becomes  insolvent.  Upon
becoming aware of such circumstances, the Company will be obligated to appoint a
successor Trustee. The Trustee may also be removed at any time by the


                                       47

<PAGE>



holders of  Certificates  evidencing  not less than 51% of the aggregate  voting
rights in the related Trust Fund. 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 such  Certificate,  the Pass-Through Rate on any such 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  such  Certificate  (or  notional  amount  thereof,   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 such Mortgage Loan  outstanding as of the first day of the month prior to the
month in which the  Distribution  Date for the  related  series of  Certificates
occurs,  after giving  effect to the payment of principal due on such first day,
subject to any Deferred  Interest.  The amount of such  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 such class's specified percentage of
each such 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  such
Certificate,  or any  combination  of such  Pass-Through  Rates,  calculated  as
described  herein 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 such Certificate because, while interest
will  accrue  on each  Mortgage  Loan  from the  first  day of each  month,  the
distribution  of such  interest will be made on the 25th day (or, if such 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 such  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 Mortgage  Rates (net of servicing fees and
any Excess Spread or Excluded  Spread) of the related  Mortgage  Loans (the "Net
Mortgage  Rate") 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 in respect of such Mortgage Loans by the Company,  the
Master  Servicer and others,  or  conversions  of ARM Loans to a fixed  interest
rate. See "Mortgage Loan  Program--Representations by Sellers" and "Descriptions
of the  Certificates--Assignment  of Mortgage Loans" 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
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. Such a 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
holders thereof. In certain  circumstances,  rapid prepayments may result in the
failure of such holders to recoup their original  investment.  In addition,  the
yield to maturity on certain 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 certain 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
thereof, the greater will be the effect on an investor's yield to maturity.


                                       48

<PAGE>



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.  Unless
otherwise  specified in the related Prospectus  Supplement,  prepayments in full
will reduce the amount of interest distributed in the following month to holders
of  Certificates  entitled to  distributions  of interest  because the resulting
Prepayment Interest Shortfall will not be covered by Compensating  Interest. See
"Description  of  the  Certificates--Prepayment   Interest  Shortfalls."  Unless
otherwise specified in the related Prospectus  Supplement,  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  such  partial
prepayment is received.  As a result,  unless otherwise specified in the related
Prospectus  Supplement,  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 such 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  Loan-to-Value  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
Loan-to-Value  Ratios greater than 80% and with no Primary  Insurance  Policies.
The yield on any class of  Certificates  and the  timing of  principal  payments
thereon  may also be affected by certain  modifications  or actions  that may be
approved by the Master  Servicer as described  herein under  "Description of the
Certificates--Collection  and Other  Servicing  Practices," in connection with a
Mortgage Loan that is in default (or if a default is reasonably foreseeable).

         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  certain  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
generally  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's underwriting guidelines,  and may accordingly increase the
risk of default with respect to the related Mortgage Loan.

         The   Mortgage   Rates  on  certain  ARM  Loans   subject  to  negative
amortization  generally 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 generally 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 such 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 the  principal  balance  thereof  and will bear
interest at the  applicable  Mortgage  Rate.  The addition of any such  Deferred
Interest to the  principal  balance of any related  class of  Certificates  will
lengthen the weighted  average  life thereof and may  adversely  affect yield to
holders  thereof.  In  addition,  with  respect to certain ARM Loans  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 the principal
balance  thereof,  and since such excess will be applied to reduce the principal
balance of the related class or classes of  Certificates,  the weighted  average
life of such  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 such  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--Principal and Interest on the Certificates."

                     MATURITY AND PREPAYMENT CONSIDERATIONS

         As indicated  above under "The Mortgage  Pools," 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 such  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 such Mortgage Loans, is expected to be a
substantial  amount) will generally depend on the Mortgagor's  ability to obtain
refinancing  of such 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.  Unless otherwise  specified in the related  Prospectus  Supplement,
neither the Company,  the Master  Servicer nor any of their  affiliates  will be
obligated to refinance or repurchase  any Mortgage Loan or to sell the Mortgaged
Property.

         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 such  prepayment  standards or models 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 such series that would be outstanding on specified payment dates
for such series based on the assumptions  stated in such 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.

         A number of factors, including 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,  may  affect  prepayment
experience. 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 certain transfers by the Mortgagor of the underlying Mortgaged Property.
Unless  the  related  Prospectus  Supplement  indicates  otherwise,  the  Master
Servicer  will  generally  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 under certain
conditions  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 and Related  Matters--Enforceability of
Certain  Provisions" for a description of certain  provisions of the Pooling and
Servicing   Agreement  and  certain  legal  developments  that  may  affect  the
prepayment experience on the Mortgage Loans.

         In addition,  certain 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 a certain  extent,  depend on the interest  rates on such
underlying Mortgage Loans.

         A Subservicer may allow the refinancing of a Mortgage Loan in any Trust
Fund 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 such a refinancing,  the new loan would
not be included in the related Trust Fund and, therefore, such 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.   Such  programs  may  include,   without
limitation,  modifications of existing loans, general or targeted solicitations,
the 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 such
Mortgage Loans which may be removed from the related  Mortgage Pool. As a result
of such  programs,  with respect to the Mortgage Pool  underlying any Trust Fund
(i) the rate of principal  prepayments  of the Mortgage  Loans in such  Mortgage
Pool may be higher than would otherwise be the case, and (ii) in some cases, the
average  credit or  collateral  quality of the Mortgage  Loans  remaining in the
Mortgage Pool may decline.



                                       50

<PAGE>



         All  statistics  known to the  Company  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 such 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 Company is not aware
of any historical  prepayment  experience with respect to mortgage loans secured
by properties located in Puerto Rico and, accordingly, prepayments on such 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,  such adjustments  generally will (i) not increase or decrease such
Mortgage Rates by more than a fixed  percentage  amount on each adjustment date,
(ii) not increase such Mortgage Rates over a fixed percentage  amount during the
life of any ARM Loan and (iii) 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 certain 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 certain  circumstances,  the Master Servicer,  the Company 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 Fund. See "The Pooling and Servicing Agreement--Termination; Retirement of
Certificates."


                     CERTAIN LEGAL ASPECTS OF MORTGAGE LOANS

         The following discussion contains summaries of certain legal aspects of
mortgage  loans that are  general  in nature.  Because  such 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 located.  In
some  states,  a mortgage,  deed of trust or deed to secure debt  creates a lien
upon the real property  encumbered by the mortgage.  It is not prior to the lien
for  real  estate  taxes  and   assessments  and  other  charges  imposed  under
governmental police powers. Priority with respect to such 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  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 the case of a land trust,  there
are three parties  because 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  borrower  executes a  separate  undertaking  to make
payments  on the  mortgage  note.  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,  generally with a power
of sale, to the trustee to secure  payment of the  obligation.  A deed to secure
debt  typically  has two parties,  pursuant to which the  borrower,  or grantor,
conveys title to the real property to the grantee,  or lender,  generally with a
power of sale,  until such time as 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
certain 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 debt
instrument (a "Cooperative  Note") evidencing a Cooperative Loan will be secured
by  a  security  interest  in  shares  issued  by  the  related  corporation  (a
"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


                                       51

<PAGE>



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 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.
Such a lien or security interest is not, in general,  prior to liens in favor of
the cooperative corporation for unpaid assessments or common charges.

         Unless otherwise  specified in the related Prospectus  Supplement,  all
Cooperative buildings relating to the Cooperative Loans are located in the State
of New York. 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
generally 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 such 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
at maturity.  The inability of the  Cooperative  to refinance a mortgage and its
consequent inability to make such 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  pursuant
to   the   proprietary    lease,    which   rental   payment   represents   such
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.  Subject to 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 Code) of a corporation that qualifies as a "cooperative housing corporation"
within the meaning of Section  216(b)(1) of the 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
certain real estate taxes  allowable as a deduction  under Section 216(a) of the
Code to the  corporation  under Sections 163 and 164 of the Code. In order for a
corporation to qualify under Section  216(b)(1) of the Code for its taxable year
in which  such items are  allowable  as a  deduction  to the  corporation,  such
section requires,  among other things,  that at least 80% of the gross income of
the  corporation  be  derived  from its  tenant-stockholders.  By virtue of this
requirement,  the status of a corporation  for purposes of Section  216(b)(1) of
the 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 such section for any particular year. In the event that such a Cooperative
fails to qualify for one or more years, the value of the collateral securing any
related  Cooperative Loans could be significantly  impaired because no deduction
would be allowable to tenant-stockholders  under Section 216(a) of the 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 Code, the likelihood that such a failure would be permitted to continue over
a period of years appears remote.


  Foreclosure on Mortgage Loans



                                       52

<PAGE>



         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 generally  accomplished by a non-judicial  trustee's sale under a
specific  provision in the deed of trust which authorizes the trustee or lender,
as  applicable,  to sell the property upon any default by the borrower under the
terms of the note or deed of  trust.  In  addition  to any  notice  requirements
contained in a deed of trust,  in some states,  the trustee must record a notice
of  default  and send a copy to the  borrower/trustor  and to any person who has
recorded  a request  for a copy of  notice of  default  and  notice of sale.  In
addition,  in some states,  the trustee or lender,  as applicable,  must provide
notice  to any  other  individual  having  an  interest  of  record  in the real
property,  including  any  junior  lienholders.  If the  deed  of  trust  is not
reinstated  within 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.
Generally,  the action is initiated by the service of legal  pleadings  upon all
parties having an interest of record in the real property.  Delays in completion
of the  foreclosure  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 such 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 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  referee  for a credit bid less than or equal to the unpaid
principal  amount of the mortgage or deed of trust,  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
such 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 such repairs at its own expense as 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 such  actions.  The process may be  expedited  if the mortgage can obtain the
consent of the defendant to the execution of a deed in lieu of foreclosure.

         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 such property and (b) is occupied by
the mortgagor as his principal  residence,  the mortgagor of such property has a
right to be paid the first $1,500 from the proceeds  obtained on the public sale
of such  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 such sale.  Such
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



                                       53

<PAGE>



         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,  subject to
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 cancelled by the  Cooperative  for failure by the  tenant-stockholder  to pay
rent or other obligations or charges owed by such tenant-stockholder,  including
mechanics'   liens  against  the   Cooperative's   building   incurred  by  such
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 such 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  such  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 such 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.  Such
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
(the "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 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,  a deed to
secure debt or  foreclosure of a mortgage,  the borrower and  foreclosed  junior
lienors or other parties are given a statutory  period  (generally  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

         Certain  states have  imposed  statutory  prohibitions  which limit the
remedies of a beneficiary  under a deed of trust or a mortgagee under a mortgage
or a deed to secure debt. In some states (including California),  statutes limit
the  right of the  beneficiary  or  mortgagee  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, even if obtainable under applicable law, may be of little
value to the mortgagee or beneficiary if there are no trust assets against which
such  deficiency  judgment  may be  executed.  Some state  statutes  require the
beneficiary 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 certain other
states,  the lender has the option of  bringing a personal  action  against  the
borrower on the debt without first exhausting such security; however, in some of
these states,  the lender,  following  judgment on such personal action,  may be
deemed to have elected a remedy and may be precluded  from  exercising  remedies
with respect to the security. Consequently, the practical effect of the election
requirement,  in those states  permitting  such  election,  is that lenders will
usually  proceed  against the  security  first  rather than  bringing a personal
action  against  the  borrower.  Finally,  in certain  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  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 certain
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.

         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  in  respect of a mortgage  loan on such  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 pursuant
to a plan  confirmed  pursuant  to 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 Code may, in certain 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.

         Certain  of  the  Mortgage  Loans  may be  subject  to  special  rules,
disclosure  requirements  and other  provisions  that were added to the  federal
Truth-in-Lending  Act by the  Homeownership  and Equity  Protection  Act of 1994
(such Mortgage Loans, "High Cost Loans"), if such Mortgage Loans were originated
on or after October 1, 1995, are not mortgage loans made to finance the purchase
of the mortgaged property and have interest rates or origination costs in excess
of certain  prescribed  levels.  Purchasers  or assignees of any High Cost Loan,
including  any Trust  Fund,  could be liable for all  claims and  subject to all
defenses arising under such provisions that the borrower could assert


                                       55

<PAGE>



against the  originator  thereof.  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 generally 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 (the "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 certain 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 pursuant
to 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 generally  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,  such as 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 mortgage  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 ("Title V"), provides that state usury limitations shall not
apply  to  certain  types  of  residential   first  mortgage  loans,   including
cooperative loans, originated by certain 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  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 set forth in the related Prospectus  Supplement,  each
Seller,  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.  Such  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 ("Title VIII").
Title VIII provides  that,  notwithstanding  any state law to the contrary,  (i)
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, (ii)  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


                                       56

<PAGE>



mortgage  instruments by federal credit unions and (iii) 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 Federal Home Loan Bank Board,
predecessor to the Office of Thrift Supervision,  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 such  provisions.  Certain
states have taken such action.


Environmental Legislation

         Under the federal Comprehensive  Environmental  Response,  Compensation
and Liability Act of 1980, as amended ("CERCLA"), and under state law in certain
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 certain  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 (the  "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  certain  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. Such cleanup costs may be substantial. It
is possible that such cleanup costs could become a liability of a Trust Fund and
reduce the amounts otherwise  distributable to the holders of the related series
of  Certificates.  Moreover,  certain  federal  statutes  and certain  states by
statute  impose a lien  for any  cleanup  costs  incurred  by such  state on the
property  that is the subject of such cleanup costs (an  "Environmental  Lien").
All  subsequent  liens on such property  generally are  subordinated  to such 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 such 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 Company nor any Master
Servicer  will be required by any  Agreement to undertake  any such  evaluations
prior to  foreclosure or accepting a deed-in-lieu  of  foreclosure.  The Company
does not make any  representations  or warranties  or assume any liability  with
respect to the absence or effect of contaminants on any related real property or
any casualty resulting from the presence or effect of contaminants. However, the
Company will not be obligated to foreclose on related real  property or accept a
deed-in-lieu  of foreclosure  if it knows or reasonably  believes that there are
material contaminated conditions on such property. A failure so to foreclose may
reduce the amounts  otherwise  available  to  Certificateholders  of the related
series.

         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  Relief  Act, a  borrower  who  enters  military
service after the  origination  of such  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 such  borrower's
active duty status, unless a court orders otherwise upon application of the


                                       57

<PAGE>



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
Fund, 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 such 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  certain  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  certain  states,  there  are  or  may  be  specific
limitations upon the late charges which a lender may collect from a borrower for
delinquent  payments.  Certain  states also limit the amounts  that a lender may
collect  from a borrower  as an  additional  charge if the loan is  prepaid.  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  ("RICO")  statute can be seized by the government if the
property  was used in, or purchased  with the  proceeds  of, such 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.

         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  ("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.

                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

General

         The following is a general discussion of certain  anticipated  material
federal income tax  consequences  of the purchase,  ownership and disposition of
the  Certificates  offered  hereunder.  This  discussion  is directed  solely to
Certificateholders  that hold the  Certificates  as  capital  assets  within the
meaning of Section  1221 of the Code and does not purport to discuss all federal
income tax  consequences  that may be  applicable  to  particular  categories of
investors,  some of which  (such  as  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  herein or in a  Prospectus  Supplement.  In  addition  to the federal
income tax consequences  described herein,  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 Fund, or a portion thereof,  which the Master Servicer will
covenant to elect to have  treated as a REMIC under  Sections  860A through 860G
(the "REMIC Provisions") of the Code. The Prospectus  Supplement for each series
of  Certificates  will indicate  whether a REMIC election (or elections) will be
made for the related  Trust Fund and,  if such an  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  Fund,  the  federal  income
consequences  of  the  purchase,   ownership  and  disposition  of  the  related
Certificates  will  be set  forth  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.

         The  following  discussion  is based in part upon the  rules  governing
original  issue  discount  that are set forth in Sections  1271 through 1273 and
Section 1275 of the Code and in the Treasury  regulations issued thereunder (the
"OID  Regulations"),  and in part upon the  REMIC  Provisions  and the  Treasury
regulations  issued thereunder (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  certain  issues  relevant  to,  and in  some
instances  provide  that  they are not  applicable  to,  securities  such as the
Certificates.


REMICs


Classification of REMICs

         Upon  the  issuance  of each  series  of  REMIC  Certificates,  Thacher
Proffitt & Wood or Orrick,  Herrington & Sutcliffe LLP,  counsel to the Company,
will deliver their  opinion  generally to the effect that,  assuming  compliance
with all provisions of the related Pooling and Servicing Agreement,  the related
Trust Fund (or each applicable  portion thereof) will qualify as a REMIC and the
REMIC  Certificates  offered with respect thereto will be considered to evidence
ownership of "regular  interests"  ("REMIC Regular  Certificates")  or "residual
interests"  ("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 Code for such  status  during  any
taxable  year,  the Code provides that the entity will not be treated as a REMIC
for such year and  thereafter.  In that  event,  such 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
below. Although the Code authorizes the Treasury Department to issue regulations
providing relief in the event of an inadvertent  termination of REMIC status, no
such regulations have been issued. Any such relief, moreover, may be accompanied
by sanctions,  such as the  imposition of a corporate tax on all or a portion of
the Trust Fund's income for the period in which the requirements for such status
are not  satisfied.  The Pooling and  Servicing  Agreement  with respect to each
REMIC will include provisions  designed to maintain the Trust Fund's status as a
REMIC under the REMIC  Provisions.  It is not anticipated that the status of any
Trust Fund 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 Code and assets described in Section
7701(a)(19)(C)  of the Code in the same  proportion that the assets of the REMIC
underlying such 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


                                       59

<PAGE>



described  in  Section  856(c)(3)(B)  of  the  Code  to  the  extent  that  such
Certificates  are treated as "real estate  assets" within the meaning of Section
856(c)(4)(A) of the Code. In addition,  the REMIC Regular  Certificates  will be
"qualified mortgages" within the meaning of Section 860G(a)(3)(C) of the Code if
transferred  to another  REMIC on its  startup  day in  exchange  for regular or
residual  interests  therein.  The  determination  as to the  percentage  of the
REMIC's assets that constitute assets described in the foregoing sections of the
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 such
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 such 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)  may  not be  treated  entirely  as  assets  described  in the  foregoing
sections.  If the assets of a REMIC include  Additional  Collateral  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  such
characterizations.  If so, the related  Prospectus  Supplement will describe the
Mortgage  Loans  (including  Additional  Collateral  Loans)  that  may not be so
treated.  The REMIC Regulations do provide,  however,  that payments on Mortgage
Loans held pending  distribution  are considered  part of the Mortgage Loans for
purposes of Section 856(c)(4)(A) of the Code.


Tiered REMIC Structures

         For  certain  series  of  REMIC  Certificates,  two  or  more  separate
elections may be made to treat designated  portions of the related Trust Fund as
REMICs ("Tiered  REMICs") for federal income tax purposes.  Upon the issuance of
any such  series  of REMIC  Certificates,  Thacher  Proffitt  & Wood or  Orrick,
Herrington & Sutcliffe LLP,  counsel to the Company,  will deliver their opinion
generally 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 Code,
and "loans secured by an interest in real property" under Section 7701(a)(19)(C)
of the Code, and whether the income on such  Certificates is interest  described
in Section  856(c)(3)(B)  of the 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

         Certain REMIC Regular  Certificates  may be issued with "original issue
discount"  within the  meaning of Section  1273(a) of the Code.  Any  holders of
REMIC Regular Certificates issued with original issue discount generally 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 such income. In addition,  Section  1272(a)(6) of the 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 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 such  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 (the "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 such REMIC  Regular
Certificate.  The prepayment assumption used by the Master Servicer in reporting
original  issue  discount  for each series of REMIC  Regular  Certificates  (the
"Prepayment  Assumption")  will be  consistent  with this  standard  and will be
disclosed in the related Prospectus Supplement. However, neither the Company 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.



                                       60

<PAGE>



         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 less than a substantial amount of a particular class of REMIC
Regular  Certificates  is sold for cash on or prior to the date of their initial
issuance (the "Closing Date"), the issue price for such class will be treated as
the  fair  market  value  of such  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  such  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 such 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  thereof will vary according to the  characteristics  of
such REMIC Regular  Certificates.  If the original issue discount rules apply to
such Certificates, the related Prospectus Supplement will describe the manner in
which such 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 ("IRS").

         Certain classes of the REMIC Regular  Certificates  may provide for the
first interest  payment with respect to such  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" (as defined  herein) 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  such accrued  interest.  In such 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 such
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 such REMIC Regular Certificate. However, the OID Regulations
state that all or some  portion  of such  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  such an  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 such REMIC Regular  Certificate,  by multiplying
(i) the number of complete  years  (rounding  down for  partial  years) from the
issue date until such  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 such 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 such de minimis
original issue discount and a fraction,  the numerator of which is the amount of
such 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 such 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 such 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 such 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 such period, begins on the
Closing Date),  a calculation  will be made of the portion of the original issue
discount that accrued during such 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 such REMIC Regular


                                       61

<PAGE>



Certificate  during  the  accrual  period  of  amounts  included  in the  stated
redemption  price,  over (ii) the  adjusted  issue  price of such 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 such
Certificate,  increased by the aggregate  amount of original issue discount that
accrued with respect to such Certificate in prior accrual  periods,  and reduced
by the amount of any  distributions  made on such 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 such 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 such  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 such
uncertificated regular interests be transferred together.

         A subsequent  purchaser of a REMIC Regular  Certificate  that purchases
such  Certificate at a cost (excluding any portion of such 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 such  Certificate.  However,  each such
daily portion will be reduced,  if such cost is in excess of its "adjusted issue
price," in proportion  to the ratio such excess bears to the aggregate  original
issue discount  remaining to be accrued on such 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 such Certificate at the beginning of the accrual period which includes
such day, plus (ii) the daily  portions of original  issue discount for all days
during such accrual period prior to such day minus (iii) any principal  payments
made  during  such  accrual  period  prior  to such  day  with  respect  to such
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 Code such a
Certificateholder  generally  will be required  to allocate  the portion of each
such distribution  representing  stated 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, such election will apply to all market
discount bonds acquired by such  Certificateholder  on or after the first day of
the first  taxable year to which such  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 such an 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 such Certificateholder  acquires during the taxable year of
the  election or  thereafter,  and  possibly  previously  acquired  instruments.
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 such  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 Code if
such market discount is less than 0.25% of the remaining stated redemption price
of such 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."  Such 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 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


                                       62

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: (i) on the basis
of a constant  yield  method,  (ii) 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
(iii) 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 such
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 such 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 such  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  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  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
such deferred interest expense would not exceed the market discount that accrues
during such  taxable year and is, in general,  allowed as a deduction  not later
than the year in which such market  discount is  includible  in income.  If such
holder elects to include  market  discount in income  currently as it accrues on
all market discount  instruments acquired by such 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 such 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 such a REMIC Regular Certificate may elect under Section
171 of the Code to amortize  such premium  under the constant  yield method over
the life of the  Certificate.  If made,  such an 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 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 such Certificates have
original  issue  discount)  will also apply in  amortizing  bond  premium  under
Section 171 of the Code.

         Realized Losses

         Under  Section  166 of the Code,  both  corporate  holders of the REMIC
Regular  Certificates and noncorporate holders of the REMIC Regular Certificates
that acquire such  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 Code until such holder's Certificate becomes wholly worthless
(i.e.,  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 such  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 such 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 such 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 such 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,  subject to the  limitations
noted in this  discussion,  the net  loss of the  REMIC  for  each day  during a
calendar  quarter that such holder owned such 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
Prospectus Supplement.  The daily amounts will then be allocated among the REMIC
Residual   Certificateholders   in  proportion  to  their  respective  ownership
interests on such 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  below 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  subject to  limitations  under Section 469 of the Code on
the deductibility of "passive losses."

         A  holder  of  a  REMIC  Residual   Certificate   that  purchased  such
Certificate  from a prior  holder of such  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 such
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 certain  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 such REMIC
Residual  Certificate from a prior holder of such Certificate at a price greater
than (or less than) the adjusted  basis (as defined  herein) such REMIC Residual
Certificate  would  have  had  in  the  hands  of an  original  holder  of  such
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 such REMIC Residual Certificate will be taken
into  account in  determining  the income of such holder for federal  income tax
purposes.  Although it appears  likely that any such payment would be includible
in income  immediately upon its receipt,  the IRS might assert that such 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 such  payments,  holders  of REMIC  Residual  Certificates  should
consult their tax advisors  concerning the treatment of such payments for income
tax purposes.

         The amount of income REMIC Residual Certificateholders will be required
to report (or the tax  liability  associated  with such  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 such REMIC
Residual  Certificateholders  for the  corresponding  period  may  significantly
adversely  affect  such  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. Such 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
such  interests  in order to  determine  the basis of the REMIC in the  Mortgage
Loans and other property held by the REMIC.



                                       64

<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 (that is, under the constant yield method taking into account
the  Prepayment  Assumption).  However,  a REMIC that acquires loans at a market
discount must include such  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 such  discount  will be  includible in the income of the REMIC as it
accrues, in advance of receipt of the cash attributable to such 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 Code to amortize any premium on the Mortgage
Loans.  Premium on any  Mortgage  Loan to which  such  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 a price in excess
of the stated redemption price of such class (such excess, "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 such  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 Code (which allows such  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 such expenses will be allocated
as a separate item to the holders of REMIC Residual Certificates, subject to the
limitation  of  Section  67  of  the  Code.  See  "--Possible   Pass-Through  of
Miscellaneous  Itemized  Deductions."  If the  deductions  allowed  to the REMIC
exceed its gross income for a calendar quarter, such 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 such 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 such  related
Certificateholder.

         A REMIC Residual  Certificateholder is not allowed to take into account
any net loss for any  calendar  quarter to the extent such net loss exceeds such
REMIC  Residual   Certificateholder's  adjusted  basis  in  its  REMIC  Residual
Certificate as of the close of such calendar quarter  (determined without regard
to such net loss).  Any loss that is not currently  deductible by reason of this
limitation may be carried forward  indefinitely to future calendar quarters and,
subject to 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 may be subject to additional  limitations under the Code, as to which
such 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 such REMIC Residual Certificate.  To the extent a distribution
on a REMIC Residual  Certificate exceeds such adjusted basis, it will be treated
as gain from the sale of such  REMIC  Residual  Certificate.  Holders of certain
REMIC Residual  Certificates may be entitled to distributions  early in the term
of the  related  REMIC  under  circumstances  in which their bases in such REMIC
Residual  Certificates  will not be sufficiently  large that such  distributions
will be treated as  nontaxable  returns of  capital.  Their  bases in such 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 Fund. However,  such basis increases may not occur until the
end of the  calendar  quarter,  or perhaps the end of the  calendar  year,  with
respect to which such REMIC  taxable  income is allocated to the REMIC  Residual
Certificateholders. To the extent such REMIC Residual Certificateholders initial
bases are less than the distributions to such REMIC Residual Certificateholders,
and  increases in such initial  bases either occur after such  distributions  or
(together with their initial bases) are less than the amount of such


                                       65

<PAGE>



distributions, gain will be recognized to such REMIC Residual Certificateholders
on such  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 such  REMIC  Residual  Certificate  to such  holder and the
adjusted  basis such 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 such REMIC Residual
Certificate  over (ii) the sum of the "daily  accruals" (as defined  herein) for
each day during such quarter that such REMIC  Residual  Certificate  was held by
such 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
such REMIC Residual  Certificate before the beginning of such 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 such class will be treated as
the fair market value of such 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 (i) will not
be permitted to be offset by deductions,  losses or loss  carryovers  from other
activities,  (ii) will be treated as "unrelated  business  taxable income" to an
otherwise  tax-exempt  organization  and (iii) 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.   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 such 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
Code,  excluding any net capital gain), will be allocated among the shareholders
of such trust in proportion to the dividends  received by such shareholders from
such 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 such
shareholder. Treasury regulations yet to be issued could apply a similar rule to
regulated investment companies, common trust funds and certain 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 such transfer is disregarded, the purported
transferor  will continue to remain liable for any taxes due with respect to the
income on such "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  certain  restrictions  under the terms of the  related  Pooling  and
Servicing  Agreement  that are  intended to reduce the  possibility  of any such
transfer being disregarded. Such


                                       66

<PAGE>



restrictions  will require each party to a transfer to provide an affidavit that
no purpose of such  transfer is to impede the  assessment  or collection of tax,
including  certain   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 such 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 such 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 such purchaser.

         The related  Prospectus  Supplement will disclose whether offered REMIC
Residual Certificates may be considered  "noneconomic"  residual interests under
the REMIC  Regulations.  Any such disclosure  that a REMIC Residual  Certificate
will not be considered "noneconomic" will be based upon certain assumptions, and
the Company 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

         On  December  24,  1996,  the  IRS  released  final   regulations  (the
"Mark-to-Market  Regulations")  relating to the  requirement  that a  securities
dealer mark to market securities held for sale to customers. This 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  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 such fees and expenses should be allocated to
the holders of the related REMIC Regular  Certificates.  Unless otherwise stated
in the related Prospectus  Supplement,  such 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 such
individual's,  estate's or trust's share of such fees and expenses will be added
to the gross  income of such  holder  and (ii) such  individual's,  estate's  or
trust's  share of such fees and  expenses  will be  treated  as a  miscellaneous
itemized  deduction  allowable  subject to the  limitation  of Section 67 of the
Code,  which  permits  such  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 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 such  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 subject to the
limitations of either  Section 67 or Section 68 of the 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 such holder's gross income. Accordingly, such 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. Such prospective  investors should consult with their tax advisors prior
to making an investment in such Certificates.

         Tax and Restrictions on Transfers of REMIC Residual Certificates to
  Certain Organizations

         If a REMIC  Residual  Certificate  is  transferred  to a  "disqualified
organization"  (as  defined  below),  a  tax  would  be  imposed  in  an  amount
(determined under the REMIC Regulations) equal to the product of (i) 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
such REMIC  Residual  Certificate  for periods  after the  transfer and (ii) 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 such  transfer,  the  Prepayment  Assumption  and any
required or permitted clean up calls or required liquidation provided for in the
REMIC's organizational  documents.  Such a tax generally would be imposed on the
transferor of the REMIC Residual Certificate, except that where such transfer is
through  an agent for a  disqualified  organization,  the tax would  instead  be
imposed on such agent.  However,  a transferor of a REMIC  Residual  Certificate
would in no event be  liable  for such tax with  respect  to a  transfer  if the
transferee furnishes to the transferor an affidavit that the transferee is not a
disqualified  organization  and, as of the time of the transfer,  the transferor
does not have actual knowledge that such


                                       67

<PAGE>



affidavit is false. Moreover, an entity will not qualify as a REMIC unless there
are reasonable  arrangements  designed to ensure that (i) residual  interests in
such  entity are not held by  disqualified  organizations  and (ii)  information
necessary  for  the  application  of the  tax  described  herein  will  be  made
available.  Restrictions  on the  transfer of REMIC  Residual  Certificates  and
certain  other  provisions  that are intended to meet this  requirement  will be
included  in the Pooling  and  Servicing  Agreement,  including  provisions  (a)
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 such status and agreeing to obtain a similar  affidavit
from any person to whom it shall  transfer the REMIC Residual  Certificate,  (b)
providing that any transfer of a REMIC Residual  Certificate to a  "disqualified
person"  shall be null and void and (c)  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 (a) and (b) above.

         In addition,  if a "pass-through entity" (as defined below) includes in
income excess  inclusions  with respect to a REMIC Residual  Certificate,  and a
disqualified  organization  is the record  holder of an interest in such entity,
then a tax will be imposed on such 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 such 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 such pass-through  entity furnishes to such
pass-through  entity (i) such holder's  social  security  number and a statement
under  penalties  of perjury  that such  social  security  number is that of the
record  holder or (ii) a statement  under  penalties of perjury that such 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 such tax paid by the partners).

         For these purposes, a "disqualified  organization" means (i) the United
States, any State or political subdivision thereof, any foreign government,  any
international  organization,  or any agency or  instrumentality of the foregoing
(but would not include  instrumentalities  described in Section  168(h)(2)(D) of
the Code or  Freddie  Mac),  (ii) any  organization  (other  than a  cooperative
described  in Section 521 of the Code) that is exempt from  federal  income tax,
unless it is subject to the tax  imposed by Section  511 of the Code,  (iii) any
organization  described in Section  1381(a)(2)(C) of the Code, (iv) an "electing
large  partnership"  (as  described in Section 775 of the Code) or (v) any other
person so  designated  by the Trustee  based upon an opinion of counsel that the
holding of an ownership interest in a REMIC Certificate by such person may cause
the related Trust Fund or any person  having an ownership  interest in the REMIC
Certificate  (other than such  person) to incur a liability  for any federal tax
imposed  under the Code that would not otherwise be imposed but for the transfer
of an  ownership  interest  in a REMIC  Certificate  to such  person.  For these
purposes, a "pass-through  entity" means any regulated investment company,  real
estate investment trust, trust,  partnership or certain other entities described
in Section 860E(e)(6) of the Code. In addition,  a person holding an interest in
a pass-through entity as a nominee for another person will, with respect to such
interest, be treated as a pass-through entity.

         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 such REMIC Regular
Certificate  to such  Certificateholder,  increased  by income  reported by such
Certificateholder  with  respect to such REMIC  Regular  Certificate  (including
original issue discount and market  discount  income) and reduced (but not below
zero) by  distributions  on such  REMIC  Regular  Certificate  received  by such
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 such 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 such 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 such REMIC Regular Certificate had income
accrued  thereon  at a rate  equal  to 110%  of the  "applicable  federal  rate"
(generally,  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 such
REMIC  Regular  Certificate,  over (ii) the amount of ordinary  income  actually
includible  in the  seller's  income  prior  to such  sale.  In  addition,  gain
recognized on the sale of a REMIC Regular  Certificate by a seller who purchased
such 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 Code, so that gain or loss  recognized from
the sale of a REMIC  Certificate  by a bank or thrift  institution to which such
section applies will be ordinary income or loss.



                                       68

<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 such Certificate is held as part of a "conversion  transaction"  within the
meaning of Section 1258 of the 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 such  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 such
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.

         Except as may be provided in Treasury  regulations yet to be issued, 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 Code) within six months of the date
of such sale,  the sale will be subject to the "wash sale" rules of Section 1091
of  the  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 such REMIC Residual  Certificateholders  adjusted basis in the newly-acquired
asset.

         Prohibited Transactions and Other Possible REMIC Taxes

         The  Code  imposes  a tax on  REMICs  equal  to 100% of the net  income
derived from "prohibited  transactions" (the "Prohibited  Transactions Tax"). In
general,  subject to certain 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 certain  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,  certain  contributions  to a REMIC made after the day on
which the REMIC issues all of its interests  could result in the imposition of a
tax on the REMIC  equal to 100% of the value of the  contributed  property  (the
"Contributions   Tax").  Each  Pooling  and  Servicing  Agreement  will  include
provisions designed to prevent the acceptance of any contributions that would be
subject to such 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 such 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 in  respect  of
compliance with applicable laws and  regulations.  Any such tax not borne by the
Master  Servicer  or the Trustee  will be payable out of the related  Trust Fund
resulting  in a reduction  in amounts  payable to holders of the  related  REMIC
Certificates.

         Termination

         A  REMIC  will  terminate   immediately  after  the  Distribution  Date
following  receipt by the REMIC of the final  payment in respect of 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 such REMIC
Residual Certificate is less than the Certificateholder's adjusted basis in such
Certificate,  such Certificateholder should be treated as realizing a loss equal
to the  amount of such  difference,  and such loss may be  treated  as a capital
loss.

         Reporting and Other Administrative Matters

         Solely for purposes of the  administrative  provisions of the 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


                                       69

<PAGE>



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 (the "REMIC Administrator") will prepare
such 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,  subject to certain
notice  requirements and various  restrictions  and limitations,  generally 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 generally will be required to
report such 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 such 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 such an audit, could result in an audit of such Certificateholder's return.
No REMIC will be  registered  as a tax shelter  pursuant to Section  6111 of the
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 such 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
generally  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 certain other non-individuals will
be provided  interest and original issue  discount  income  information  and the
information set forth 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 certain  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, generally 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, such 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 Section  1.6049-7(e)(2) of
the  Treasury  regulations.  Such  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  Code at a rate of 31% if  recipients  of such
payments  fail to  furnish to the payor  certain  information,  including  their
taxpayer  identification  numbers,  or otherwise  fail to establish an exemption
from such tax.  Any amounts  deducted  and  withheld  from a  distribution  to a
recipient would be allowed as a credit against such  recipient's  federal income
tax. Furthermore,  certain 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"
(as defined  below) 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 in  respect  of 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 such
Certificateholder  is not a United  States  person  and  providing  the name and
address of such 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


                                       70

<PAGE>



part I of  subchapter  J of chapter 1 of the Code),  and which was  treated as a
United States person on August 19, 1996,  may elect to continue to be treated as
a United States person  notwithstanding  the previous  sentence.  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  in  respect  of  accrued
original  issue  discount,  to such  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 such
United States shareholder's allocable portion of the interest income received by
such 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")  which  make  certain  modifications  to the  withholding,  backup
withholding and information reporting rules described above. The New Regulations
attempt to unify certification  requirements and modify reliance standards.  The
New Regulations will generally be effective for payments made after December 31,
1999,  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
"Certain 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 ERISA impose certain  fiduciary and prohibited
transaction  restrictions on employee  pension and welfare benefit plans subject
to ERISA ("ERISA Plans") and on certain 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  such  ERISA  Plans  are  invested.  Section  4975 of the Code  imposes
essentially  the  same  prohibited  transaction  restrictions  on  tax-qualified
retirement  plans  described  in  Section  401(a) of the Code and on  individual
retirement  accounts  described  in  Section  408  of  the  Code  (collectively,
"Tax-Favored Plans").

         Certain employee benefit plans, such as governmental  plans (as defined
in Section 3(32) of ERISA) and if no election has been under  Section  410(d) of
the Code,  church plans (as defined in Section 3(33) of ERISA),  are not subject
to the ERISA requirements  discussed herein.  Accordingly,  assets of such 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 such  plan that is a  tax-qualified  plan and  exempt  from  taxation  under
Sections  401(a) and 501(a) of the Code,  however,  is subject to the prohibited
transaction rules set forth in Section 503 of the Code.

          In addition  to imposing  general  fiduciary  requirements,  including
those of investment  prudence and  diversification  and the  requirement  that a
Plan's  investment be made in accordance with the documents  governing the Plan,
Section  406 of ERISA and  Section  4975 of the Code  prohibit a broad  range of
transactions  involving  "plan  assets"  of ERISA  Plans and  Tax-Favored  Plans
(collectively,  "Plans")  and  persons  ("Parties  in  Interest"  under ERISA or
"Disqualified Persons" under the Code, collectively,  "Parties in Interest") who
have  certain  specified  relationships  to the  Plans,  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  pursuant to Section  502(i) of ERISA or Section 4975 of the
Code, unless a statutory or  administrative  exemption is available with respect
to any such transaction.


Plan Asset Regulations

         An investment of Plan Assets in  Certificates  may cause the underlying
Mortgage Loans, Mortgage Securities or any other assets included in a Trust Fund
to be deemed  "plan  assets" of such  Plan.  The U.S.  Department  of Labor (the
"DOL") has  promulgated  regulations at 29 C.F.R.  Section  2510.3-101 (the "DOL
Regulations")  concerning  whether  or not a Plan's  assets  would be  deemed to
include an interest in the underlying assets of an entity (such as


                                       71

<PAGE>



a Trust Fund),  for purposes of applying  the general  fiduciary  responsibility
provisions  of ERISA  and the  prohibited  transaction  provisions  of ERISA and
Section 4975 of the Code,  when a Plan acquires an "equity  interest" (such as a
Certificate)  in such  entity.  Because of the factual  nature of certain of the
rules set forth in the DOL  Regulations,  Plan  Assets  either  may be deemed to
include an interest in the assets of an entity  (such as a Trust Fund) or may be
deemed merely to include a Plan's  interest in the  instrument  evidencing  such
equity  interest  (such as a  Certificate).  Therefore,  neither  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  "plan  assets"  ("Plan  Assets")  or  "assets  of a Plan" has the  meaning
specified  in the DOL  Regulations  and  includes an  undivided  interest in the
underlying assets of certain entities in which a Plan invests.

         The  prohibited  transaction  provisions  of  Section  406 of ERISA and
Section  4975 of the Code may apply to a Trust Fund and cause the  Company,  the
Master  Servicer,  any  Subservicer,  the Trustee,  the obligor under any credit
enhancement  mechanism or certain  affiliates thereof to be considered or become
Parties in Interest  with respect to an investing  Plan (or of a Plan holding an
interest in such an entity).  If so, the  acquisition or holding of Certificates
by or on behalf  of the  investing  Plan  could  also give rise to a  prohibited
transaction  under ERISA and/or Section 4975 of the Code,  unless some statutory
or administrative exemption is available.  Certificates acquired by a Plan would
be assets of that Plan. Under the DOL Regulations,  a Trust Fund,  including the
Mortgage Loans, Mortgage Securities or any other assets held in such Trust Fund,
may also be deemed to be assets of each Plan that acquires Certificates. Special
caution should be exercised before Plan Assets are used to acquire a Certificate
in such  circumstances,  especially  if, with respect to such Plan  Assets,  the
Company,  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 such Plan Assets;  or
(ii) has authority or  responsibility  to give (or regularly  gives)  investment
advice  with  respect  to Plan  Assets for a fee  pursuant  to an  agreement  or
understanding  that such  advice  will serve as a primary  basis for  investment
decisions with respect to such Plan Assets.

         Any person who has  discretionary  authority or control  respecting the
management or disposition of Plan Assets, and any person who provides investment
advice  with  respect to such Plan  Assets  for a fee (in the  manner  described
above),  is a fiduciary of the investing Plan. If the Mortgage  Loans,  Mortgage
Securities  or any other  assets  held in a Trust Fund were to  constitute  Plan
Assets,  then any party  exercising  management  or  discretionary  control with
respect to those Plan  Assets may be deemed to be a Plan  "fiduciary,"  and thus
subject to the fiduciary  requirements  of ERISA and the prohibited  transaction
provisions  of ERISA and Section 4975 of the Code with respect to any  investing
Plan.  In addition,  if the Mortgage  Loans,  Mortgage  Securities  or any other
assets held in a Trust Fund were to constitute Plan Assets, then the acquisition
or holding of Certificates by, on behalf of a Plan or with Plan Assets,  as well
as the  operation of such Trust Fund,  may  constitute or result in a prohibited
transaction under ERISA and the Code.


Prohibited Transaction Exemption

         The DOL has  issued an  individual  exemption,  Prohibited  Transaction
Exemption  ("PTE") 94-29,  59 Fed. Reg. 14674 (March 29, 1994) as amended by PTE
97-34,  62 Fed.  Reg.  39021 (July 21, 1997) (the  "Exemption")  to  Residential
Funding  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 such prohibited transactions pursuant to Section
4975(a) and (b) of the Code, certain transactions, among others, relating to the
servicing and operation of mortgage pools of certain secured obligations such as
Mortgage Loans, which are held in a trust and the purchase,  sale and holding of
pass-through  certificates issued by such a trust as to which (i) the Company 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 Company or an affiliate is
the Underwriter or placement agent,  provided that certain  conditions set forth
in the  Exemption  are  satisfied.  For  purposes  of  this  section,  the  term
"Underwriter"  shall include (a) the Company 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 Company 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 a Plan or with Plan Assets must be on terms that are at least as favorable to
the  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 a Plan or with  Plan  Assets  must be rated in one of the  three
highest generic rating categories by Standard & Poor's Ratings Services, Moody's
Investors  Service,  Inc.,  Duff & Phelps Credit Rating Co. or Fitch IBCA,  Inc.
(collectively,  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 Company, the Master Servicer, any Subservicer, the Trustee and
any mortgagor with respect to assets of a Trust Fund  constituting  more than 5%
of the  aggregate  unamortized  principal  balance of the assets in the  related
Trust Fund 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 Company  pursuant to the  assignment of
the  assets to the  related  Trust  Fund must  represent  not more than the fair
market  value  of such  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


                                       72

for such person's services under the related Pooling and Servicing Agreement and
reimbursement  of such person's  reasonable  expenses in  connection  therewith.
Sixth,  the Exemption states that the investing Plan or Plan Asset investor must
be an  accredited  investor as defined in Rule  501(a)(1) of Regulation D of the
Commission under the Securities Act of 1933, as amended. 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 Fund contains a Swap.

         The  Exemption  also  requires  that each Trust Fund meet the following
requirements:  (i) the Trust Fund must consist solely of assets of the type that
have been  included in other  investment  pools;  (ii)  certificates  evidencing
interests  in such  other  investment  pools  must have been rated in one of the
three highest  categories of one of the Exemption  Rating  Agencies for at least
one year prior to the  acquisition of  Certificates by or on behalf of a Plan or
with Plan Assets;  and (iii)  certificates in such other  investment  pools must
have been purchased by investors other than Plans for at least one year prior to
any acquisition of Certificates by or on behalf of a Plan or with Plan Assets.

         A  fiduciary  of  or  other  investor  of  Plan  Assets   contemplating
purchasing  a  Certificate  must  make its own  determination  that the  general
conditions set forth above will be satisfied with respect to such 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
Code by reason of Sections  4975(c)(1)(A) through (D) of the 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 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 Plan  Assets of an  Excluded  Plan by any person who has
discretionary authority or renders investment advice with respect to Plan Assets
of such Excluded Plan. For purposes of the Certificates, an "Excluded Plan" is a
Plan sponsored by any member of the Restricted Group.

         If certain 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  Code  by  reason  of  Section  4975(c)(1)(E)  of the  Code,  in
connection  with (1) the  direct or  indirect  sale,  exchange  or  transfer  of
Certificates in the initial  issuance of Certificates  between the Company or an
Underwriter  and a Plan  when the  person  who has  discretionary  authority  or
renders  investment  advice with respect to the  investment of the relevant 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 Fund or (b) an  affiliate  of such a
person,  (2) the direct or indirect  acquisition or disposition in the secondary
market of  Certificates  by a Plan or with Plan  Assets  and (3) the  holding of
Certificates by a Plan or with Plan Assets.

         Additionally,  if certain  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 Code by reason of Section  4975(c) of the Code,
for  transactions in connection with the servicing,  management and operation of
the Mortgage  Pools.  The Company  expects that the specific  conditions  of the
Exemption  required  for this  purpose  will be  satisfied  with  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 Code by reason of Section 4975(c) of
the 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 Code by reason of Sections 4975(c)(1)(A) through
(D) of the Code,  if such  restrictions  are deemed to  otherwise  apply  merely
because  a  person  is  deemed  to be a Party in  Interest  with  respect  to an
investing Plan (or a Plan holding interests in the investing entity holding Plan
Assets) by virtue of  providing  services to the Plan or such Plan Assets (or by
virtue of having certain  specified  relationships to such a person) solely as a
result of the Plan's ownership of Certificates.

         Before purchasing a Certificate,  a fiduciary or other investor of Plan
Assets should itself confirm that (a) the Certificates constitute "certificates"
for purposes of the  Exemption and (b) the specific and general  conditions  set
forth in the  Exemption  and the other  requirements  set forth 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 Plan Asset  investor  should  consider its general  fiduciary  obligations
under  ERISA in  determining  whether to  purchase  any  Certificates  with Plan
Assets.

         Any  fiduciary or other Plan Asset  investor  that proposes to purchase
Certificates  on behalf of a Plan or with Plan Assets  should  consult  with its
counsel with  respect to the  potential  applicability  of ERISA and the Code to
such  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,  such fiduciary or other Plan Asset investor should consider the
availability of the Exemption or Prohibited Transaction Class Exemption ("PTCE")
83-1 ("PTCE 83-1") for certain  transactions  involving mortgage pool investment
trusts.  However,  PTCE 83-1 does not provide  exemptive  relief with respect to
Certificates evidencing interests in Trust Funds which include Cooperative Loans
or certain types of Mortgage  Securities.  In addition,  such fiduciary or other
Plan Asset 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 Code, including Sections


                                       73

<PAGE>



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 Plan's or other Plan Asset 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  such  an
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  certain  exemptive  relief  from the
provisions of Part 4 of Title I of ERISA and Section 4975 of the Code, including
the prohibited transaction  restrictions imposed by ERISA and the related excise
taxes  imposed  by  Section  4975 of the Code,  for  transactions  involving  an
insurance company general account.  Pursuant to Section 401(c) of ERISA, the DOL
published  proposed  regulations  on December 22, 1997,  but the required  final
regulations  (the  "401(c)  Regulations")  have not been  issued  as of the date
hereof.  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 a Plan on or
before December 31, 1998,  which general account assets  constitute Plan Assets.
Section  401(c) of ERISA  generally  provides  that,  until the date which is 18
months after the 401(c)  Regulations become final, no person shall be subject to
liability  under Part 4 of Title I of ERISA or  Section  4975 of the Code on the
basis  of a claim  that the  assets  of an  insurance  company  general  account
constitute  Plan Assets,  unless (i) as otherwise  provided by the  Secretary of
Labor in the 401(c)  Regulations to prevent avoidance of the regulations or (ii)
an action is brought by the Secretary of Labor for certain breaches of fiduciary
duty which would also  constitute a violation of federal or state  criminal law.
Any assets of an insurance  company  general  account  which  support  insurance
policies or annuity contracts issued to a Plan after December 31, 1998 or issued
to Plans on or before December 31, 1998 for which the insurance company does not
comply with the 401(c)  Regulations may be treated as Plan Assets.  In addition,
because Section 401(c) does not relate to insurance  company separate  accounts,
separate account assets are still treated as Plan Assets of any Plan invested in
such separate  account.  Insurance  companies  contemplating  the  investment of
general  account  assets in the  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 Fund contains a Swap, except as otherwise  specified in the
related  Prospectus  Supplement,  transfers of such Certificates to a Plan, to a
trustee or other  person  acting on behalf of any Plan,  or to any other  person
using Plan  Assets to effect  such  acquisition  will not be  registered  by the
Trustee unless the transferee  provides the Company,  the Trustee and the Master
Servicer with an opinion of counsel satisfactory to the Company, the Trustee and
the Master  Servicer,  which  opinion will not be at the expense of the Company,
the Trustee or the Master Servicer, that the purchase of such Certificates by or
on behalf of such Plan or with 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 Code and will not subject the Company,  the Trustee
or the Master Servicer to any obligation in addition to those  undertaken in the
Pooling and Servicing Agreement.  In lieu of such 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 such  Certificates  by or on  behalf  of such  Plan or with  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 Code, will not subject
the Company, 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 such  Certificates
is an "insurance  company general  account" (as such term is defined in PTCE 95-
60), and (b) the  conditions  set forth in Sections I and III of PTCE 95-60 have
been satisfied as of the date of the acquisition of such Certificates.

Tax-Exempt Investors

         A Plan that is exempt from federal income taxation  pursuant to Section
501 of the Code (a "Tax-Exempt Investor") nonetheless will be subject to federal
income  taxation to the extent that its income is  "unrelated  business  taxable
income"  ("UBTI")  within the  meaning of Section  512 of the 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 "Certain 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  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 Fund.  Prospective
Plan investors should consult with their legal counsel  concerning the impact of
ERISA  and  the  Code  and  the  potential   consequences   to  their   specific
circumstances prior to making an investment in the Certificates.



                                       74

<PAGE>



         Any fiduciary or other investor of Plan Assets that proposes to acquire
or hold Certificates on behalf of a Plan or with 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 Code to the proposed  investment and the Exemption
and the 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,  certain  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 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  pursuant to 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 such entities.  Under
SMMEA,  if  a  State  enacted  legislation  on  or  prior  to  October  3,  1991
specifically  limiting the legal investment  authority of any such entities with
respect to "mortgage related  securities," such securities will constitute legal
investments for entities subject to such 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 such  securities,  so long as such
contractual  commitment  was  made  or such  securities  acquired  prior  to the
enactment of such legislation.

         SMMEA   also    amended    the   legal    investment    authority    of
federally-chartered depository institutions as follows: federal savings and loan
associations  and federal  savings  banks may invest in, sell or otherwise  deal
with "mortgage related  securities"  without  limitation as to the percentage of
their  assets  represented  thereby,  federal  credit  unions may invest in such
securities,  and  national  banks may  purchase  such  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 such
regulations as the applicable federal regulatory authority may prescribe.

         On April 23,  1998,  the  Federal  Financial  Institutions  Examination
Council  issued  a  revised  supervisory  policy  statement  (the  "1998  Policy
Statement") applicable to all depository institutions,  setting forth guidelines
for investments in "high-risk  mortgage  securities."  The 1998 Policy Statement
has been adopted by the Federal Reserve Board,  the Office of the Comptroller of
the Currency,  the FDIC, the National Credit Union  Administration  (the "NCUA")
and the Office of Thrift  Supervision  (the "OTS") with an effective date of May
26, 1998. The 1998 Policy  Statement  rescinds a 1992 policy  statement that had
required,  prior to purchase,  a depository  institution to determine  whether a
mortgage derivative product that it is considering acquiring is high-risk,  and,
if so, that the  proposed  acquisition  would reduce the  institution's  overall
interest rate risk. The 1998 Policy Statement  eliminates former  constraints on
investing in certain  "high-risk"  mortgage  derivative products and substitutes
broader guidelines for evaluating and monitoring investment risk.

         The  predecessor  to the OTS  issued a  bulletin,  entitled,  "Mortgage
Derivative   Products  and  Mortgage  Swaps,"  which  is  applicable  to  thrift
institutions  regulated by the OTS. The bulletin established  guidelines for the
investment by savings  institutions in certain  "high-risk"  mortgage derivative
securities  and  limitations  on  the  use  of  such  securities  by  insolvent,
undercapitalized  or  otherwise  "troubled"   institutions.   According  to  the
bulletin,  such "high-risk"  mortgage  derivative  securities include securities
having certain specified  characteristics,  which may include certain classes of
Certificates. The OTS is, however, proposing to adopt revised requirements based
on the 1998  Policy  Statement.  In  addition,  the NCUA has issued  regulations
governing federal credit union investments which prohibit  investment in certain
specified   types  of  securities,   which  may  include   certain   classes  of
Certificates.  Similar policy  statements have been issued by regulators  having
jurisdiction over other types of depository institutions.

         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 certain  investors
either to purchase  certain  classes of Certificates or to purchase any class of
Certificates  representing  more than a specified  percentage of the  investors'
assets.   The   Company   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 such investor.

                                 USE OF PROCEEDS

         Unless  otherwise  specified  in  the  related  Prospectus  Supplement,
substantially  all  of  the  net  proceeds  to be  received  from  the  sale  of
Certificates  will be applied by the Company 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 Company for general corporate
purposes.  The Company expects that it will make additional  sales of securities
similar to the Certificates  from time to time, but the timing and amount of any
such additional offerings will be dependent upon a number of factors,  including
the volume of mortgage  loans  purchased  by the  Company,  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 Company from such sale.

         The  Company  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 these
methods. Such methods are as follows:

          1. by  negotiated  firm  commitment or best efforts  underwriting  and
     public re-offering by underwriters;

          2. by placements by the Company with  institutional  investors through
     dealers; and

          3. by direct placements by the Company 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 in respect of such
Certificates.

         If underwriters are used in a sale of any  Certificates  (other than in
connection with an underwriting on a best efforts basis), such 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.  Such  underwriters  may be
broker-dealers affiliated with the Company whose identities and relationships to
the  Company  will be as set forth 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  such  series  and  the  members  of  the
underwriting syndicate, if any, will be named in such Prospectus Supplement.

         In  connection  with the  sale of the  Certificates,  underwriters  may
receive  compensation from the Company 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  such  Certificates,  and  any  discounts  or
commissions  received  by them from the  Company and any profit on the resale of
Certificates by them may be deemed to be underwriting  discounts and commissions
under the Securities Act of 1933, as amended.

         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 such  Certificates  if any are
purchased  (other than in  connection  with an  underwriting  on a best  efforts
basis) and that,  in limited  circumstances,  the  Company  will  indemnify  the
several  underwriters  and the  underwriters  will indemnify the Company against
certain civil  liabilities,  including  liabilities  under the Securities Act of
1933, as amended,  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 such
offering  and  any  agreements  to be  entered  into  between  the  Company  and
purchasers of Certificates of such series.

         The Company  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 such purchases, be deemed to be "underwriters" within
the meaning of the  Securities  Act of 1933,  as  amended,  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 such reoffer or
sale.
