        This is a Series Supplement,   dated as of September 1, 2006 (the "Series
Supplement"), to the Standard Terms of Pooling and Servicing Agreement, dated as
of September 1, 2006 and attached as Exhibit Four hereto (the   "Standard   Terms"
and, together with this Series Supplement, the "Pooling and Servicing Agreement"
or "Agreement"),   among RESIDENTIAL   FUNDING MORTGAGE SECURITIES I, INC., as the
company   (together with its permitted   successors and assigns,   the   "Company"),
RESIDENTIAL FUNDING CORPORATION, as master servicer (together with its permitted
successors   and   assigns,   the   "Master   Servicer"),    and   U.S.   BANK   NATIONAL
ASSOCIATION, as Trustee (together with its permitted successors and assigns, the
"Trustee").

                               PRELIMINARY STATEMENT

        The   Company    intends   to   sell   Mortgage    Pass-Through    Certificates
(collectively, the "Certificates"),   to be issued hereunder in multiple classes,
which in the aggregate will evidence the entire beneficial ownership interest in
the   Trust   Fund.   As   provided   herein,   the REMIC   Administrator   will make an
election   to   treat   the   entire   segregated   pool of   assets   described   in the
definition of Trust Fund, and subject to this Agreement   (including the Mortgage
Loans but excluding the Initial   Monthly   Payment   Fund,   the Yield   Maintenance
Agreement   and any   payments   thereunder   and the Reserve   Fund and any payments
therefrom),   as a real estate   mortgage   investment   conduit   (the   "REMIC") for
federal   income   tax   purposes   and   such   segregated   pool   of   assets   will be
designated as "REMIC I." The   Uncertificated   REMIC Regular I Interests   will be
"regular   interests" in REMIC I and the Class R-I Certificates   will be the sole
class of "residual   interests"   in REMIC I for purposes of the REMIC   Provisions
(as   defined    herein).    A   segregated    pool   of   assets    consisting   of   the
Uncertificated   REMIC I Regular   Interests will be designated as "REMIC II," and
the REMIC   Administrator   will   make a   separate   REMIC   election   with   respect
thereto.   The   Class   A-1   Certificates,    Class   A-2   Certificates,   Class   A-3
Certificates,    Class   A-4   Certificates,   Class   A-5   Certificates,   Class   A-6
Certificates,    Class   A-7   Certificates,   Class   A-8   Certificates,   Class   A-9
Certificates,   Class   A-10   Certificates,   Class   A-11,   Class   A-12,   Class A-P
Certificates,    Class   M-1   Certificates,   Class   M-2   Certificates,   Class   M-3
Certificates,    Class   B-1   Certificates,   Class   B-2   Certificates,   Class   B-3
Certificates   and   the   Uncertificated   REMIC   II   Regular   Interests   Z will be
"regular interests" in REMIC II and the Class R-II Certificates will be the sole
class of "residual interests" therein for purposes of the REMIC Provisions.   The
Class A-V Certificates will represent the entire beneficial   ownership   interest
in the Uncertificated REMIC II Regular Interests Z.

        The terms and provisions of the Standard   Terms are hereby   incorporated
by reference herein as though set forth in full herein. If any term or provision
contained   herein shall   conflict   with or be   inconsistent   with any   provision
contained   in the   Standard   Terms,   the terms   and   provisions   of this   Series
Supplement   shall govern.   Any   cross-reference   to a section of the Pooling and
Servicing   Agreement,   to the extent the terms of the Standard   Terms and Series
Supplement conflict with respect to that section,   shall be a cross-reference to
the   related   section   of the   Series   Supplement.   All   capitalized   terms   not
otherwise   defined   herein   shall have the   meanings   set forth in the   Standard
Terms. The Pooling and Servicing   Agreement shall be dated as of the date of the
Series Supplement.

        The following table sets forth the designation, type, Pass-Through Rate,

and certain features for each Class of Certificates   comprising the interests in
the Trust Fund created hereunder.

The Class A-9 Certificates do not have a Certificate   Principal Balance. For the
purpose of calculating interest payments, interest on the Class A-9 Certificates
will accrue on a notional amount equal to the Certificate   Principal   Balance of
the Class A-8 Certificates   immediately prior to the related   Distribution Date,
which is initially equal to $53,500,000.

The Class A-8   Certificates   will represent   ownership of a regular   interest in
REMIC II,   together   with   certain   rights to payments   to be made from   amounts
received under the Yield Maintenance Agreement or on deposit in the Reserve Fund
which will be deemed made for federal income tax purposes outside of REMIC II.

(4)      The Class A-12 Certificates do not have a Certificate Principal Balance.
         For the purpose of calculating   interest payments,   interest will accrue
        on a   notional   amount   equal to   2/25th   of the   aggregate   Certificate
        Principal    Balance   of   the   Class   A-3   and   Class   A-4   Certificates.
        Initially,   this Notional   Amount is equal to   $11,512,800.   For federal
        income   tax   purposes,   however,   interest   payments   on the Class   A-12
        Certificates   are expressed as 0.50%   multiplied by the Notional   Amount
        (as defined herein) of each of the Class A-3   Certificates and Class A-4
        Certificates.

               then   outstanding   with the Highest Priority and each other Class
               of   Subordinate   Certificates   for which the   related   Prepayment

                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

Section 1.02    Use of Words and Phrases.

        "Herein," "hereby," "hereunder," "hereof," "hereinbefore," "hereinafter"
and other   equivalent   words refer to the Pooling and   Servicing   Agreement as a
whole. All references herein to Articles, Sections or Subsections shall mean the
corresponding   Articles,   Sections and   Subsections in the Pooling and Servicing
Agreement.   The   definitions   set forth herein include both the singular and the
plural.

        References in the Pooling and   Servicing   Agreement to "interest" on and
"principal"   of the   Mortgage   Loans   shall   mean,   with   respect   to the Sharia
Mortgage Loans,   amounts in respect profit   payments and   acquisition   payments,
respectively.

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:

        With respect to 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   placeCityLondon   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, 5.32% 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 CityLondon,   placecountry-regionEngland 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

(b)      The   Company   hereby   represents   and   warrants   to the   Trustee for the
        benefit   of   Certificateholders   that as of the   Closing   Date   (or,   if
        otherwise specified below, as of the date so specified):

(i)      No Mortgage   Loan is 30 or more days   Delinquent in payment of principal
        and   interest   as of the Cut-off   Date and no Mortgage   Loan has been so
         Delinquent   more than once in the   12-month   period prior to the Cut-off
        Date;

(ii)     The   information   set forth in Exhibit One hereto   with   respect to each
        Mortgage   Loan or the   Mortgage   Loans,   as the case may be, is true and
         correct in all material   respects at the date or dates   respecting which
        such information is furnished;

        first   day of each   month   and   terms   to   maturity   at   origination   or
        modification of not more than 30 years;

(iv)     To the best of the Company's knowledge, if a Mortgage Loan is secured by
        a Mortgaged Property with a Loan-to-Value Ratio at origination in excess
        of 80%, such Mortgage Loan is the subject of a Primary   Insurance Policy
        that   insures that (a) at least 30% of the Stated   Principal   Balance of

        95.00% and 90.01%, (b) at least 25% of such balance if the Loan-to-Value
        Ratio is between 90.00% and 85.01%, and (c) at least 12% of such balance
        if the Loan-to-Value   Ratio is between 85.00% and 80.01%. To the best of

        by fire and other   hazards as required by the Program   Guide,   including

        casualty   insurance at the Mortgagor's   expense,   and on the Mortgagor's
        failure to do so,   authorizes   the holder of the   Mortgage to obtain and
        maintain   such   insurance   at   the   Mortgagor's    expense   and   to   seek
        reimbursement therefor from the Mortgagor;

(viii)   Immediately   prior   to the   assignment   of   the   Mortgage   Loans   to the

        Mortgage   Loan   free   and   clear of any   pledge,   lien,   encumbrance   or
        security    interest    (other   than   rights   to   servicing    and   related

         related    Mortgage    Loan    that   the    Mortgaged    Property    would   be
        owner-occupied and therefore would not be an investor property as of the
        date of origination of such Mortgage Loan. No Mortgagor is a corporation
        or a partnership;

(xi)     None of the Mortgage Loans are Buydown Mortgage Loans;

(xii)    Each   Mortgage   Loan   constitutes   a qualified   mortgage   under   Section
        860G(a)(3)(A)    of    the    Code    and    Treasury    Regulations    Section
        1.860G-2(a)(1);

(xiii)   A policy of title   insurance   was   effective   as of the   closing of each
        Mortgage   Loan and is valid and   binding   and   remains in full force and
        effect, unless the Mortgaged Properties are located in the State of Iowa
        and an   attorney's   certificate   has been   provided as   described in the
        Program Guide;

(xiv)    Except with respect to three Mortgage Loans,   none of the Mortgage Loans

        in connection   with the   refinancing   thereof),   the related   Seller has
        represented that either (a) the value of the related Mortgaged   Property
        as of the date the Mortgage   Loan was   originated   was not less than the
        appraised   value   of such   property   at the time of   origination   of the
        refinanced   Mortgage Loan or (b) the Loan-to-Value Ratio of the Mortgage
        Loan as of the date of origination of the Mortgage Loan generally   meets
        the Company's underwriting guidelines;

(xvi)    Interest on each   Mortgage   Loan is calculated on the basis of a 360-day
        year consisting of twelve 30-day months;

(xvii)   None of the   Mortgage   Loans   contains   in the related   Mortgage   File a
        Destroyed Mortgage Note; and

(xviii) None of the   Mortgage   Loans   are   Pledged   Asset   Loans   or   Additional
        Collateral Loans.

It is understood and agreed that the representations and warranties set forth in
this Section 2.03(b) shall survive delivery of the respective Custodial Files to
the Trustee or the Custodian.

        Upon discovery by any of the Company, the Master Servicer,   the Trustee,
or the Custodian of a breach of any of the   representations   and   warranties set
forth   in this   Section   2.03(b)   that   materially   and   adversely   affects   the
interests of the   Certificateholders in any Mortgage Loan, the party discovering
such breach shall give prompt written notice to the other parties (any Custodian
being so obligated under a Custodial Agreement);   provided, however, that in the
event of a breach   of the   representation   and   warranty   set   forth in   Section
2.03(b)(xii),   the party   discovering   such breach shall give such notice within
five days of discovery. Within 90 days of its discovery or its receipt of notice
of   breach,   the   Company   shall   either   (i) cure such   breach in all   material
respects or (ii) purchase such Mortgage Loan from the Trust Fund at the Purchase
Price and in the manner set forth in Section   2.02;   provided   that the   Company
shall have the option to   substitute   a Qualified   Substitute   Mortgage   Loan or
Loans   for such   Mortgage   Loan if such   substitution   occurs   within   two years
following the Closing Date;   provided that if the omission or defect would cause
the Mortgage Loan to be other than a "qualified   mortgage" as defined in Section
860G(a)(3) of the Code,   any such cure or   repurchase   must occur within 90 days
from the date   such   breach   was   discovered.   Any   such   substitution   shall be
effected   by the   Company   under the same terms and   conditions   as   provided in
Section 2.04 for   substitutions   by   Residential   Funding.   It is understood and
agreed that the   obligation of the Company to cure such breach or to so purchase
or   substitute   for any Mortgage Loan as to which such a breach has occurred and
is continuing shall constitute the sole remedy   respecting such breach available
to the   Certificateholders   or the Trustee on behalf of the   Certificateholders.
Notwithstanding   the   foregoing,   the   Company   shall   not be   required   to cure
breaches   or   purchase   or   substitute   for   Mortgage   Loans as provided in this
Section   2.03(b) if the   substance of the breach of a   representation   set forth
above also constitutes fraud in the origination of the Mortgage Loan.

and   interest   of the   Company   in and to the   Uncertificated   REMIC   I   Regular
Interests   to the   Trustee   for the   benefit   of the   Holders   of each   Class of
Certificates (other than the Class R-I Certificates).   The Trustee   acknowledges

Mortgaged   Properties   it is to   service   are   situated,   if and   to the   extent
required by applicable law to enable the   Subservicer to perform its obligations
hereunder and under the   Subservicing   Agreement,   and in either case shall be a
Freddie Mac,   Fannie Mae or HUD approved   mortgage   servicer.   In addition,   any
Subservicer   of a   Mortgage   Loan   insured   by the FHA   must be an   FHA-approved
servicer,   and any Subservicer of a Mortgage Loan guaranteed by the VA must be a
VA-approved   servicer.   Each Subservicer of a Mortgage Loan shall be entitled to
receive and retain,   as provided in the related   Subservicing   Agreement   and in

Master   Servicer and Wells Fargo, if any, will be upon such terms and conditions
as are   consistent   with   this   Agreement   and as the   Master   Servicer   and the
Subservicer   have agreed,   which may not be consistent   with the Program   Guide.
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.   The Master Servicer and a
Subservicer   may   enter   into    amendments    thereto   or   a   different   form   of
Subservicing   Agreement,   and the form   referred   to or   included in the Program
Guide is merely provided for information and shall not be deemed to limit in any
respect the discretion of the Master   Servicer to modify or enter into different
Subservicing   Agreements;    provided,   however,   that   any   such   amendments   or
different   forms shall be   consistent   with and not violate   the   provisions   of
either this   Agreement or the Program   Guide in a manner which would   materially
and adversely affect the interests of the Certificateholders.   The Program Guide
and any other   Subservicing   Agreement   entered into between the Master Servicer
and any Subservicer shall require the Subservicer to accurately and fully report
its borrower credit files to each of the Credit Repositories in a timely manner.

        Prepayments in Full, Curtailments, Subsequent Recoveries and repurchases
        (including   deemed   repurchases   under   Section   3.07(b) of the Standard

        Date and the   amount of any Class A-P   Collection   Shortfalls   remaining

        the Eligible Funds for such Distribution Date; minus

                 Date, all priorities   relating to distributions as described in
                 Section   4.02(b)   of   this   Series   Supplement   in   respect   of
                 principal among the Senior   Certificates   (other than the Class
                  A-P Certificates) will be disregarded,   and (i) an amount equal
                 to the Discount   Fraction of the principal portion of scheduled

                 (other than the Class A-P   Certificates) pro rata in accordance
                 with   their   respective    outstanding    Certificate    Principal

                 amount    distributable    to   the    Class    A-1   and   Class   A-2
                 Certificates   in respect of the aggregate   Accrued   Certificate
                 Interest   thereon   and in respect of their   aggregate   pro rata
                 portion of the Senior   Principal   Distribution   Amount   will be

                 Certificate Principal Balance thereof has been reduced to zero.

(d)               After the reduction of the   Certificate   Principal   Balances of
                 the Senior Certificates (other than the Class A-P Certificates)
                 to zero but prior to the Credit   Support   Depletion   Date,   the
                 Senior   Certificates   (other   than the Class A-P   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 Class A-P Certificates,   Class A-V
                 Certificates, Class M Certificates and Class B Certificates, in

(e)               In addition to the foregoing distributions, with respect to any
                 Subsequent   Recoveries,   the Master Servicer shall deposit such
                 funds   into   the    Custodial    Account    pursuant    to   Section
                 3.07(b)(iii).   If, after   taking into   account such   Subsequent
                 Recoveries,   the   amount of a   Realized   Loss is   reduced,   the
                 amount   of   such   Subsequent   Recoveries   will   be   applied   to
                 increase   the   Certificate   Principal   Balance   of the Class of
                 Subordinate   Certificates   with the   Highest   Priority to which
                 Realized Losses,   other than Excess Bankruptcy   Losses,   Excess
                 Fraud Losses,   Excess Special   Hazard Losses and   Extraordinary
                 Losses, have been allocated, but not by more than the amount of
                 Realized    Losses    previously    allocated   to   that   Class   of
                 Certificates   pursuant   to   Section   4.05.   The   amount   of any
                  remaining Subsequent Recoveries will be applied to increase the
                 Certificate Principal Balance of the Class of Certificates with
                 the next   Lower   Priority,   up to the   amount of such   Realized
                 Losses   previously   allocated   to that   Class   of   Certificates
                 pursuant to Section 4.05. Any remaining   Subsequent   Recoveries
                 will in turn be applied to increase the   Certificate   Principal
                 Balance   of the   Class of   Certificates   with   the   next   Lower
                 Priority up to the amount of such   Realized   Losses   previously
                 allocated   to that Class of   Certificates   pursuant   to Section
                 4.05,   and so on.   Holders   of such   Certificates   will   not be
                 entitled   to any   payment in   respect   of   Accrued   Certificate
                 Interest   on the   amount   of such   increases   for any   Interest
                 Accrual Period   preceding the   Distribution   Date on which such
                 increase   occurs.   Any such   increases   shall be applied to the
                 Certificate Principal Balance of each Certificate of such Class
                 in accordance with its respective Percentage Interest.

(f)               On each   Distribution   Date, the Trustee will first transfer to
                 the   Certificate   Account and then   distribute to the Class A-8
                 Certificates   any amounts on deposit in the Reserve   Fund in an
                  amount up to the Yield Supplement   Amount for such Distribution
                 Date.

(g)               Each   distribution   with   respect to a   Book-Entry   Certificate
                 shall be paid to the   Depository,   as Holder   thereof,   and the
                  Depository shall be solely responsible for crediting the amount
                 of   such    distribution   to   the   accounts   of   its   Depository
                 Participants   in accordance   with its normal   procedures.   Each
                  Depository Participant shall be responsible for disbursing such
                 distribution to the   Certificate   Owners that it represents and
                 to each   indirect   participating   brokerage   firm (a "brokerage
                 firm" or   "indirect   participating   firm") for which it acts as
                 agent.   Each brokerage firm shall be responsible for disbursing
                 funds to the Certificate Owners that it represents. None of the
                 Trustee, the Certificate   Registrar,   the Company or the Master
                 Servicer   shall   have any   responsibility   therefor   except   as
                 otherwise provided by this Series Supplement or applicable law.

(h)               Except as   otherwise   provided in Section   9.01,   if the Master
                 Servicer   anticipates that a final distribution with respect to
                 any Class of Certificates will be made on a future Distribution
                 Date, the Master Servicer shall, no later than 40 days prior to
                 such final   distribution,   notify the   Trustee   and the Trustee
                 shall,   not   earlier   than the 15th day and not later   than the
                 25th day of the month   next   preceding   the month of such final
                 distribution,   distribute,   or cause to be   distributed to each
                 Holder of such   Class of   Certificates   a notice to the   effect
                 that: (i) the Trustee   anticipates that the final   distribution
                  with respect to such Class of Certificates will be made on such
                 Distribution   Date but only upon   presentation and surrender of
                 such   Certificates at the office of the Trustee or as otherwise
                 specified   therein,   and (ii) no interest   shall accrue on such
                 Certificates   from and   after the end of the   related   Interest
                 Accrual Period. In the event that   Certificateholders   required
                 to surrender their Certificates   pursuant to Section 9.01(c) do
                 not surrender their   Certificates for final   cancellation,   the
                 Trustee   shall cause funds   distributable   with respect to such
                 Certificates to be withdrawn from the   Certificate   Account and
                 credited to a separate   escrow   account for the benefit of such
                 Certificateholders as provided in Section 9.01(d).

(i)               On each Distribution   Date preceding the Accretion   Termination
                 Date for any Class of Accrual Certificates,   an amount equal to
                 the   Accrued   Certificate   Interest   that   would   otherwise   be
                 distributed to such Class of Accrual Certificates will be added
                  to the   Certificate   Principal   Balance   thereof   and   will   be
                 distributed   to the holders of the related   Class of   Accretion

                 accrue   interest   at   a   rate   of   6.25%   per   annum.   On   each
                 Distribution   Date on or after the Accretion   Termination   Date
                 for any   Class of   Accrual   Certificates,   the   entire   Accrued

        the Master Servicer. (See Section 4.04 of the Standard Terms)

Section 4.05    Allocation of Realized Losses.

        Prior to each Distribution Date, the Master Servicer shall determine the
total   amount   of   Realized   Losses,    if   any,   that   resulted   from   any   Cash
Liquidation, Servicing Modification, Debt Service Reduction, Deficient Valuation
or REO Disposition that occurred during the related Prepayment Period or, in the
case of a Servicing   Modification   that   constitutes a reduction of the interest
rate on a Mortgage Loan, the amount of the reduction in the interest   portion of
the   Monthly   Payment   due during the   related   Due   Period.   The amount of each
Realized   Loss shall be   evidenced   by an   Officers'   Certificate.   All Realized
Losses, other than Excess Special Hazard Losses,   Extraordinary   Losses,   Excess
Bankruptcy Losses or Excess Fraud Losses, shall be allocated as follows:   first,
to the Class B-3 Certificates   until the Certificate   Principal   Balance thereof
has been   reduced   to zero;   second,   to the   Class B-2   Certificates   until the
Certificate   Principal   Balance thereof has been reduced to zero;   third, to the
Class B-1 Certificates until the Certificate   Principal Balance thereof has been
reduced to zero;   fourth,   to the Class M-3   Certificates   until the Certificate
Principal   Balance   thereof has been   reduced to zero;   fifth,   to the Class M-2
Certificates until the Certificate Principal Balance thereof has been reduced to
zero;   sixth,   to the Class M-1   Certificates   until the   Certificate   Principal
Balance thereof has been reduced to zero; and, thereafter,   if any such Realized
Losses are on a Discount   Mortgage   Loan,   to the Class A-P   Certificates   in an
amount equal to the Discount Fraction of the principal portion thereof,   and the
remainder of such Realized Losses on the Discount   Mortgage Loans and the entire
amount of such Realized Losses on Non-Discount   Mortgage Loans will be allocated
among all the Senior   Certificates   (other than the Class A-V   Certificates   and
Class A-P   Certificates) in the case of the principal   portion of such loss on a
pro rata basis and among all of the Senior   Certificates   (other   than the Class
A-P Certificates) in the case of the interest portion of such loss on a pro rata
basis,   as   described   below;   provided,   however,   that such   losses   otherwise
allocable   to the   Class A-1   Certificates   will be   allocated   to the Class A-2
Certificates, as long as the Class A-2 Certificates remain outstanding.

         On any Distribution Date, Realized Losses will be allocated as set forth
herein after distributions of principal on the Certificates as set forth herein.

        As used herein,   an   allocation of a Realized Loss on a "pro rata basis"
among two or more specified Classes of Certificates means an allocation on a pro
rata   basis,   among the   various   Classes   so   specified,   to each such Class of
Certificates   on the   basis   of their   then   outstanding   Certificate   Principal
Balances prior to giving effect to distributions to be made on such Distribution
Date in the case of the   principal   portion of a   Realized   Loss or based on the
Accrued Certificate   Interest thereon payable on such Distribution Date (without
regard to any Compensating   Interest for such Distribution   Date) in the case of
an   interest   portion of a Realized   Loss;   provided   that for the   purposes   of
determining "pro rata", the Certificate   Principal   Balance of each class of the
Accrual   Certificates   shall   be   deemed   to be the   lesser   of (a) the   related
Certificate   Principal Balance thereof as of the Closing Date or (b) the related
Certificate   Principal Balance thereof as of such date of determination.   Except
as provided in the following   sentence,   any allocation of the principal portion
of   Realized   Losses   (other   than   Debt   Service   Reductions)   to   a   Class   of
Certificates shall be made by reducing the Certificate Principal Balance thereof
by the amount so allocated, which allocation shall be deemed to have occurred on
such   Distribution   Date;   provided   that no such   reduction   shall   reduce   the
aggregate   Certificate Principal Balance of the Certificates below the aggregate
Stated Principal   Balance of the Mortgage Loans. Any allocation of the principal
portion   of   Realized   Losses
