<PAGE>


                                    ARTICLE I

                                   DEFINITIONS

        Section   1.01     Definitions.

        Whenever used in this Agreement, the following words and phrases, unless
the   context   otherwise   requires,   shall have the   meanings   specified   in this
Article.

        Accrued Certificate Interest: With respect to each Distribution Date, as
to any   Class   or   Subclass   of   Certificates   (other   than any   Principal   Only
Certificates),   interest   accrued during the related   Interest Accrual Period at
the related   Pass-Through Rate on the Certificate   Principal Balance or Notional
Amount thereof   immediately prior to such Distribution Date. Accrued Certificate
Interest, other than the Class A-9 Certificates and Class A-12 Certificates will
be   calculated   on the   basis of a 360-day   year,   consisting   of twelve   30-day
months.   Accrued Certificate Interest on the Class II-A-9 Certificates and Class
II-A-12   Certificates is calculated on the basis of the actual number of days in
the related   Interest   Accrual   Period and a 360-day   year. In each case Accrued
Certificate Interest on any Class or Subclass of Certificates will be reduced by
the amount of:

        (i)     Prepayment   Interest   Shortfalls   on all   Mortgage   Loans   in the
               related   Loan   Group (to the   extent   not   offset   by the   Master
               Servicer with a payment of   Compensating   Interest as provided in
               Section 4.01),

        (ii)    the interest   portion   (adjusted to the Net Mortgage Rate (or the
               Modified   Net   Mortgage   Rate in the case of a Modified   Mortgage
               Loan)) of Realized   Losses on all   Mortgage   Loans in the related
               Loan Group not allocated   solely to one or more specific   Classes
               of Certificates pursuant to Section 4.05,

        (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 the   subordination
               provided by the Class M   Certificates   and Class B   Certificates,
               including   interest   that is not   collectible   from the Mortgagor
               pursuant to the Servicemembers   Civil Relief Act, as amended,   or
               similar   legislation   or   regulations   as in effect   from time to
               time, all allocated as described below.

The Class I-A Percentage of these   reductions   with respect to the Group I Loans
will be   allocated   among   the   Holders   of the Group I Senior   Certificates   in
proportion to the amounts of Accrued   Certificate   Interest that would have been
payable to those   Certificates   from the Group I Loans on that Distribution Date
absent such   reductions.   The Class II-A   Percentage   of these   reductions   with
respect to the Group II Loans will be   allocated   among the Holders of the Group
II Senior   Certificates   in   proportion   to the   amounts of Accrued   Certificate
Interest   that would have been payable to those   Certificates   from the Group II
Loans on that Distribution   Date absent such reductions.   The remainder of these
reductions will be allocated   among the Holders of the Class M Certificates   and
the Class B   Certificates   in   proportion to the   respective   amounts of Accrued

                                       6
<PAGE>

Certificate   Interest   that would have been   payable on that   Distribution   Date
absent these   reductions.   In the case of each class of Class M Certificates and
Class B Certificates, Accrued Certificate Interest on that class will be further
reduced by the interest portion   (adjusted to the Net Mortgage Rate) of Realized
Losses that are allocated   solely to such Class of Class M Certificates   or such
Class of Class B in Certificates pursuant to Section 4.05.

        Adjustable   Rate   Certificates:   Any of the Class II-A-1,   Class II-A-2,

                respective    Recalculated    Percentages   (the   portion   of    such
               aggregate   reduction so allocated to any Non-Maturing Class,   the
               "Adjustment    Percentage");    and   (d)   for    purposes   of    such
               Distribution   Date,   the Prepayment   Distribution   Percentage   of
               each   Non-Maturing   Class   shall   be equal to the sum of (1)   the
               Prepayment   Distribution    Percentage   thereof,    calculated    in
               accordance with the provisions in paragraph (ii) above as if   the
               Certificate   Principal   Balance of each   Maturing   Class had   not
               been    reduced   to   zero,    plus   (2)   the   related     Adjustment
               Percentage.

Principal   Balance of all of the Mortgage Loans (or REO Properties)   immediately

        Section 1.03. Determination of LIBOR.

        LIBOR   applicable to the   calculation of the   Pass-Through   Rates on the
Adjustable   Rate   Certificates   for any Interest   Accrual Period (other than 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, will equal the rate for one month United
States   dollar   deposits   that appears on the   Telerate   Screen Page 3750 of the
Moneyline   Telerate Capital Markets Report 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, any other service for displaying LIBOR or comparable rates as
may be selected by the Trustee after consultation with the Master Servicer), the
rate   will be the   Reference   Bank   Rate.   The   "Reference   Bank   Rate"   will be
determined   on the   basis of the rates at which   deposits   in U.S.   Dollars   are
offered by the   reference   banks   (which shall be any 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 rounded up to the next multiple of
1/16%. 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,   5.33% per   annum;   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,   after consultation with the
Master Servicer,   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 on any LIBOR Rate Adjustment
Date and the Master Servicer's subsequent   calculation of the Pass-Through Rates
applicable to each of the Adjustable Rate Certificates for the relevant Interest
Accrual Period, in the absence of manifest error, will be final and binding.

                                       30
<PAGE>

        Promptly   following   each LIBOR Rate   Adjustment   Date the Trustee shall
supply the Master   Servicer   with the results of its   determination   of LIBOR on
such date.   Furthermore,   the Trustee will supply the Pass-Through Rates on each
of the   Adjustable   Rate   Certificates   for   the   current   and   the   immediately
preceding Interest Accrual Period via the Trustee's internet website,   which may
be obtained by telephoning the Trustee at (800) 735-7777.

        Notwithstanding the foregoing, for the purpose of determining the amount
of any payment to be under each of the Yield Maintenance Agreements,   LIBOR will
be calculated as provided in the related Yield Maintenance Agreement.
