        This is a Series   Supplement,   dated as of March 1,   2005   (the   "Series

Supplement"), to the Standard Terms of Pooling and Servicing Agreement, dated as

of December 1, 2004 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   REMIC I (as   defined   herein),   and   subject   to this   Agreement

(excluding   the   Rounding   Account,   the Reserve   Fund and the   Initial   Monthly

Payment   Fund),   as a real estate   mortgage   investment   conduit (a "REMIC") for

federal   income   tax   purposes   and   such   segregated   pool   of   assets   will be

designated   as "REMIC I." The   Uncertificated   REMIC Regular   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 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-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   Class A-V REMIC Regular   Interests 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 Class A-V REMIC Regular Interests.

 

        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   context   otherwise   requires,   shall have the   meanings   specified   in this

Article.

 

        Bankruptcy   Amount:   As of any date of determination   prior to the first

anniversary   of the Cut-off Date, an amount equal to the excess,   if any, of (A)

$100,000 over (B) the aggregate amount of Bankruptcy   Losses allocated solely to

one or more specific   Classes of Certificates in accordance with Section 4.05 of

this Series   Supplement.   As of any date of   determination on or after the first

anniversary of the Cut-off Date, an amount equal to the excess, if any, of

 

               (1) the lesser of (a) the Bankruptcy   Amount calculated as of the

        close of business on the Business   Day   immediately   preceding   the most

        recent anniversary of the Cut-off Date coinciding with or preceding such

        date   of   determination   (or,   if   such   date   of   determination   is   an

        anniversary of the Cut-off Date, the Business Day immediately   preceding

        such   date of   determination)   (for   purposes   of this   definition,   the

        "Relevant Anniversary") and (b) the greater of

 

     (A)   the greater of (i) 0.0006 times the aggregate principal balance of all

          the Mortgage Loans in the Mortgage Pool as of the Relevant Anniversary

          (other    than    Additional    Collateral    Loans,    if   any)   having   a

          Loan-to-Value    Ratio   at   origination   which   exceeds   75%   and   (ii)

          $100,000; and

 

     (B)   the greater of (i) the   product of (x) an amount   equal to the largest

          difference   in   the   related    Monthly   Payment   for   any   Non-Primary

          Residence Loan   remaining in the Mortgage Pool (other than   Additional

          Collateral Loans, if any) which had an original Loan-to-Value Ratio of

          80% or greater that would result if the Net Mortgage   Rate thereof was

          equal to the weighted   average (based on the principal   balance of the

          Mortgage   Loans as of the   Relevant   Anniversary)   of the Net Mortgage

          Rates of all Mortgage Loans as of the Relevant   Anniversary less 1.25%

          per annum, (y) a number equal to the weighted   average   remaining term

          to maturity,   in months, of all Non-Primary   Residence Loans remaining

          in the Mortgage Pool as of the Relevant Anniversary,   and (z) one plus

          the   quotient   of   the   number   of   all   Non-Primary   Residence   Loans

          remaining   in the   Mortgage   Pool   divided   by   the   total   number   of

          Outstanding   Mortgage   Loans in the   Mortgage   Pool as of the Relevant

          Anniversary,   and (ii)   $50,000,   over   (2) the   aggregate   amount   of

          Bankruptcy   Losses allocated solely to one or more specific Classes of

          Certificates   in   accordance   with   Section   4.05   since the   Relevant

          Anniversary.

 

        The   Bankruptcy   Amount   may be further   reduced by the Master   Servicer

(including   accelerating the manner in which such coverage is reduced)   provided

that prior to any such   reduction,   the Master Servicer shall (i) obtain written

confirmation   from each Rating Agency that such   reduction   shall not reduce the

rating   assigned to any Class of   Certificates   by such Rating   Agency   (without

giving   effect to the   Certificate   Policy in the case of ratings of the Insured

Certificates by Fitch or S&P) below the lower of the then-current   rating or the

rating   assigned   to such   Certificates   as of the   Closing   Date by such Rating

Agency and (ii) provide a copy of such written confirmation to the Trustee.

such Class to zero;   (b) the   Prepayment   Distribution   Percentage of each other

Class of Subordinate Certificates (any such Class, a "Non-Maturing Class") shall

be recalculated in accordance with the provisions in paragraph (ii) above, as if

zero (such percentage as recalculated,   the "Recalculated Percentage");   (c) the

total amount of the reductions in the Prepayment Distribution Percentages of the

Maturing Class or Classes pursuant to clause (a) of this sentence,   expressed as

        Upon discovery by any of the Company,   the Master Servicer,   the Trustee

or any 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

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

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

any Custodian of a breach of any of the representations and warranties made in a

Seller's   Agreement   that have been   assigned   to the   Trustee   pursuant to this

Section 2.04 or of a breach of any of the representations and warranties made in

the Assignment   Agreement (which, for purposes hereof, will be deemed to include

any other cause   giving rise to a   repurchase   obligation   under the   Assignment

Agreement)   in   respect of any   Mortgage   Loan which   materially   and   adversely

affects the interests of the Certificateholders in such 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).   The Master

Servicer shall promptly notify the related Seller or Residential Funding, as the

case may be, of such breach and request that such Seller or Residential Funding,

as the case may be, either (i) cure such breach in all material   respects within

if the   breach   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,

repurchase   or   substitution   must occur within 90 days from the date the breach

was discovered.   If the breach of representation   and warranty that gave rise to

the obligation to repurchase or substitute a Mortgage Loan pursuant to Section 4

of the   Assignment   Agreement was the   representation   and warranty set forth in

clause (xxxi) of Section 4 thereof,   then the Master Servicer shall request that

Residential Funding pay to the Trust Fund,   concurrently with and in addition to

the   remedies   provided   in the   preceding   sentence,   an   amount   equal   to any

liability,   penalty or expense that was actually   incurred and paid out of or on

behalf of the Trust Fund,   and that directly   resulted   from such breach,   or if

incurred and paid by the Trust Fund thereafter,   concurrently with such payment.

In   the   event   that   Residential   Funding   elects   to   substitute   a   Qualified

Substitute   Mortgage Loan or Loans for a Deleted   Mortgage Loan pursuant to this

Section 2.04,   Residential   Funding shall deliver to the Trustee for the benefit

of the   Certificateholders   with respect to such Qualified   Substitute   Mortgage

Loan or Loans,   the original   Mortgage Note, the Mortgage,   an Assignment of the

Mortgage in recordable form if required pursuant to Section 2.01, and such other

documents and agreements as are required by Section 2.01, with the Mortgage Note

endorsed   as   required   by Section   2.01.   No   substitution   will be made in any

calendar month after the Determination Date for such month. Monthly Payments due

with respect to Qualified Substitute Mortgage Loans in the month of substitution

shall not be part of the Trust Fund and will be retained by the Master   Servicer

and   remitted   by the   Master   Servicer   to   Residential   Funding   on   the   next

succeeding   Distribution   Date. For the month of substitution,   distributions to

the   Certificateholders   will   include   the   Monthly   Payment   due on a   Deleted

Mortgage   Loan   for such   month   and   thereafter   Residential   Funding   shall be

entitled to retain all   amounts   received   in respect of such   Deleted   Mortgage

Loan.   The Master   Servicer shall amend or cause to be amended the Mortgage Loan

Schedule,   and, if the Deleted   Mortgage Loan was a Discount   Mortgage Loan, the

Schedule of Discount   Fractions,   for the benefit of the   Certificateholders   to

reflect the removal of such Deleted   Mortgage Loan and the   substitution   of the

Qualified   Substitute   Mortgage   Loan or Loans   and the   Master   Servicer   shall

deliver the amended   Mortgage Loan Schedule,   and, if the Deleted   Mortgage Loan

was a Discount Mortgage Loan, the amended Schedule of Discount Fractions, to the

Trustee. Upon such substitution, the Qualified Substitute Mortgage Loan or Loans

shall be subject to the terms of this   Agreement   and the   related   Subservicing

Agreement in all respects,   the related   Seller shall be deemed to have made the

representations and warranties with respect to the Qualified Substitute Mortgage

Loan contained in the related Seller's Agreement as of the date of substitution,

insofar as Residential   Funding's rights in respect of such   representations and

warranties are assigned to the Company pursuant to the Assignment Agreement, and

the Company and the Master Servicer shall be deemed to have made with respect to

 

 

                                       23

<PAGE>

 

any Qualified Substitute Mortgage Loan or Loans, as of the date of substitution,

the covenants, representations and warranties set forth in this Section 2.04, in

Section 2.03 hereof and in Section 4 of the Assignment Agreement, and the Master

Servicer   shall be obligated   to   repurchase   or   substitute   for any   Qualified

Substitute   Mortgage   Loan as to which a   Repurchase   Event (as   defined   in the

Assignment   Agreement)   has   occurred   pursuant   to Section 4 of the   Assignment

Agreement.

 

        In connection with the substitution of one or more Qualified   Substitute

Mortgage Loans for one or more Deleted   Mortgage Loans, the Master Servicer will

determine   the amount (if any) by which the aggregate   principal   balance of all

such Qualified   Substitute Mortgage Loans as of the date of substitution is less

than the aggregate Stated   Principal   Balance of all such Deleted Mortgage Loans

(in each case after application of the principal portion of the Monthly Payments

due   in   the   month   of    substitution    that   are   to   be   distributed   to   the

Certificateholders   in the month of   substitution).   Residential   Funding   shall

deposit the amount of such   shortfall   into the Custodial   Account on the day of

substitution, without any reimbursement therefor. Residential Funding shall give

notice   in   writing   to the   Trustee   of   such   event,   which   notice   shall   be

accompanied by an Officers'   Certificate as to the calculation of such shortfall

and   (subject to Section   10.01(f))   by an Opinion of Counsel to the effect that

such   substitution will not cause (a) any federal tax to be imposed on the Trust

Fund,   including   without   limitation,   any federal   tax imposed on   "prohibited

transactions"   under Section   860F(a)(1) of the Code or on "contributions   after

the startup date" under Section 860G(d)(1) of the Code or (b) any portion of any

REMIC   to   fail   to   qualify   as   such   at any   time   that   any   Certificate   is

outstanding.

 

        It is   understood   and   agreed   that the   obligation   of the   Seller   or

Residential   Funding, as the case may be, to cure such breach or purchase (or in

the case of   Residential   Funding to   substitute   for) such   Mortgage Loan as to

which such a breach has occurred and is   continuing   and to make any   additional

payments required under the Assignment   Agreement in connection with a breach of

the   representation   and   warranty in clause   (xxxi) of Section 4 thereof   shall

constitute    the   sole   remedy    respecting    such   breach    available    to   the

Certificateholders or the Trustee on behalf of Certificateholders. If the Master

Servicer is Residential   Funding,   then the Trustee shall also have the right to

give the notification   and require the purchase or substitution   provided for in

the second preceding paragraph in the event of such a breach of a representation

or   warranty   made   by   Residential   Funding   in the   Assignment   Agreement.   In

connection   with the purchase of or   substitution   for any such Mortgage Loan by

Residential   Funding, the Trustee shall assign to Residential Funding all of the

Trustee's right, title and interest in respect of the Seller's Agreement and the

Assignment Agreement applicable to such Mortgage Loan.

 

Section 2.05    Execution and Authentication of Certificates.

 

        The Trustee   acknowledges the assignment to it of the Mortgage Loans and

the   delivery   of the   Mortgage   Files to it, or any   Custodian   on its   behalf,

subject to any exceptions noted, together with the assignment to it of all other

assets   included   in the Trust   Fund,   receipt of which is hereby   acknowledged.

Concurrently with such delivery and in exchange therefor, the Trustee,   pursuant

to the written request of the Company   executed by an officer of the Company has

executed and caused to be   authenticated   and   delivered to or upon the order of

the   Company   the   Certificates   in   authorized    denominations   which   evidence

ownership of the entire Trust Fund.

Section 2.06 Conveyance of Uncertificated REMIC Regular Interests; Acceptance by

        the Trustee.

 

        The Company, as of the Closing Date, and concurrently with the execution

and delivery hereof,   does hereby assign without   recourse all the right,   title

and interest of the Company in and to the Uncertificated REMIC 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 receipt of the

Uncertificated   REMIC Regular Interests and declares that it holds and will hold

the same in trust for the   exclusive   use and   benefit of all present and future

Holders of each Class of Certificates   (other than the Class R-I   Certificates).

The rights of the   Holders of each Class of   Certificates   (other than the Class

R-I   Certificates)   to receive   distributions   from the   proceeds of REMIC II in

respect of such Classes,   and all ownership   interests of the Holders of Classes

in such distributions, shall be as set forth in this Agreement.

        (c) On or after the occurrence of the Credit Support   Depletion Date but

prior to the   reduction   of the   Certificate   Principal   Balance   of the   Senior

Support   Certificates   to zero,   all   priorities   relating to   distributions   as

described   above in respect of   principal   among the   various   Classes of Senior

Certificates   (other than the Class A-P Certificates)   will be disregarded,   and

(i) the remaining   Senior Principal   Distribution   Amount will be distributed to

the Senior   Certificates   (other   than the Class A-P   Certificates)   pro rata in

accordance with their respective   outstanding   Certificate   Principal   Balances,

(ii) the related   Senior   Interest   Distribution   Amount will be   distributed as

described   in   Section   4.02(a)(i)   and   (iii) an amount   equal to the   Discount

Fraction   of   the   principal   portion   of   scheduled   payments   and   unscheduled

will be distributed among such Certificates in the following priority: first, to

the Super Senior Certificates,   up to an amount equal to the Accrued Certificate

 

 

                                       34

Interest thereon; second to the Super Senior Certificates, up to an amount equal

to the Super Senior Optimal Principal   Distribution   Amount, in reduction of the

Certificate Principal Balance thereof,   until such Certificate Principal Balance

has been reduced to zero;   third, to the Senior Support   Certificates,   up to an

amount equal to the Accrued   Certificate   Interest   thereon;   and fourth, to the

Senior Support   Certificates,   the remainder,   until the   Certificate   Principal

Balance thereof has been reduced to zero.

 

        (d) On or after the occurrence of the Credit Support   Depletion Date and

after the reduction of the Certificate   Principal   Balance of the Senior Support

Certificates   to zero, all   priorities   relating to   distributions   as described

above in respect of principal among the various   classes of Senior   Certificates

(other   than   the   Class   A-P   Certificates)   will be   disregarded,   and (i) the

remaining Senior Principal Distribution Amount will be distributed to the Senior

Certificates (other than the Class A-P Certificates) pro rata in accordance with

their respective   outstanding   Certificate   Principal Balances,   (ii) the Senior

Interest   Distribution   Amount   will be   distributed   as   described   in   Section

4.02(a)(i)   and (iii) an amount equal to the Discount   Fraction of the principal

portion of scheduled payments and unscheduled   collections   received or advanced

in respect of the Discount   Mortgage   Loans will be distributed to the Class A-P

Certificates.

 

        (e) 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,   the Class A-V   Certificates and the Subordinate

Certificates, in each case as described herein.

 

        (f) 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.

 

        (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") 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.

<PAGE>

 

        (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 60 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,   mail 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)    Notwithstanding    the   priorities   relating   to   distributions   of

principal among the Insured   Certificates   described   above, on any Distribution

Date,   distributions in respect of principal on the Insured Certificates will be

allocated among the Certificate Owners of the Insured   Certificates as set forth

in Section   4.10. On each   Distribution   Date on which amounts are available for

distributions in reduction of the Certificate   Principal   Balance of the Insured

Certificates   the   aggregate   amount   available for such   distributions   will be

rounded upward by the Rounding Amount. Such rounding will be accomplished on the

first   Distribution Date on which   distributions in reduction of the Certificate

Principal   Balance of the Insured   Certificates are made by withdrawing from the

Rounding   Account the Rounding Amount for deposit into the Certificate   Account,

and such   Rounding   Amount   will be added to the amount   that is   available   for

distributions in reduction of the Certificate   Principal   Balance of the Insured

Certificates.   On each succeeding   Distribution   Date on which   distributions in

reduction of the Certificate   Principal Balance of the Insured   Certificates are

made, first, the aggregate amount available for distribution in reduction of the

Certificate   Principal   Balance of the Insured   Certificates   will be applied to

repay the   Rounding   Amount   withdrawn   from the   Rounding   Account on the prior

Distribution Date and then, the remainder of such allocable amount, if any, will

be similarly rounded upward through another withdrawal from the Rounding Account

and   such   determined   Rounding   Amount   will be   added   to the   amount   that is

available for distribution in reduction of the Certificate   Principal Balance of

the Insured Certificates.   Any funds remaining in the Rounding Account after the

Certificate   Principal   Balance of the Insured   Certificates   is reduced to zero

shall be distributed to the Class R-II Certificateholders.

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

 

Section 4.05    Allocation of Realized Losses.

 

        (a) 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 shall 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 any such Realized Losses

otherwise allocable to the Class A-2 Certificates will be allocated to the Class

A-3   Certificates   until the   Certificate   Principal   Balance   thereof   has been

reduced to zero. Any Excess Special Hazard   Losses,   Excess   Bankruptcy   Losses,

Excess Fraud Losses, Extraordinary Losses on Non-Discount Mortgage Loans will be

allocated among the Senior   Certificates (other than the Class A-P Certificates)

and   Subordinate   Certificates,   on a pro rata basis,   as described   below.   The

principal portion of such Realized Losses on the Discount Mortgage Loans will be

allocated   to the Class A-P   Certificates   in an   amount   equal to the   Discount

Fraction   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 the Senior   Certificates   (other than the

Class A-P   Certificates) and Subordinate   Certificates,   on a pro rata basis, as

described below; as described below. Any Realized Losses otherwise   allocable to

the Insured Certificates will be covered by the Certificate Policy.

<PAGE>

 

        (b) 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.   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 (other than

Debt Service   Reductions) to the Subordinate   Certificates then outstanding with

the Lowest Priority shall be made by operation of the definition of "Certificate

Principal   Balance"   and by   operation   of the   provisions   of Section   4.02(a).

Allocations of the interest portions of Realized Losses (other than any interest

rate   reduction   resulting   from a   Servicing   Modification)   shall   be   made in

proportion to the amount of Accrued Certificate Interest and by operation of the

definition of "Accrued Certificate   Interest" and by operation of the provisions

of Section   4.02(a).   Allocations   of the   interest   portion of a Realized   Loss

resulting   from an   interest   rate   reduction   in   connection   with a   Servicing

Modification   shall be made by operation of the   provisions of Section   4.02(a).

Allocations of the principal portion of Debt Service Reductions shall be made by

operation of the   provisions   of Section   4.02(a).   All Realized   Losses and all

other losses   allocated to a Class of   Certificates   hereunder will be allocated

among the   Certificates of such Class in proportion to the Percentage   Interests

evidenced thereby; provided that if any Subclasses of the Class A-V Certificates

have been issued   pursuant to Section   5.01(c),   such Realized   Losses and other

losses   allocated to the Class A-V   Certificates   shall be allocated   among such

Subclasses   in   proportion   to the   respective   amounts of   Accrued   Certificate

Interest payable on such   Distribution Date that would have resulted absent such

reductions.

Servicer for the related   Distribution Date, withdraw funds from the Certificate

Account to repay to the   Rounding   Account   the   Rounding   Amount from the prior

Distribution Date as contemplated in Section 4.02(i).

        Distributions in reduction of the Certificate   Principal   Balance of the

Insured Certificates will be made in integral multiples of $1,000 at the request

Certificates and at the request of Living Owners of such Insured Certificates or

by mandatory distributions by Random Lot, pursuant to clauses (a) and (d) below,

or on a pro rata basis pursuant to clause (e) below.

 

        (a) On each Distribution Date on which distributions in reduction of the

Certificate   Principal   Balance   of the   Insured   Certificates   are   made,   such

Owners of the Insured Certificates:

 

               (i) any   request by the   personal   representatives   of a Deceased

Holder or by a surviving tenant by the entirety,   by a surviving joint tenant or

by a   surviving   tenant in common,   but not   exceeding   an   aggregate   amount of

$100,000 per request; and

 

        (ii) any   request by a Living   Owner,   but not   exceeding   an   aggregate

        Thereafter,   distributions   will be made,   with   respect to the   Insured

Certificates,   as provided in clauses (i) and (ii) above up to a second $100,000

and $10,000, respectively. This sequence of priorities will be repeated for each

request   for   principal   distributions   made by the   Certificate   Owners   of the

Insured Certificates until all such requests have been honored.

 

        Requests for   distributions   in reduction of the   Certificate   Principal

Balance of the Insured   Certificates   presented on behalf of Deceased Holders in

accordance   with the provisions of clause (i) above will be accepted in order of

their receipt by the Depository.   Requests for distributions in reduction of the

Certificate    Principal   Balance   of   the   Insured   Certificates    presented   in

order of their   receipt   by the   Depository   after   all   requests   presented   in

accordance    with   clause   (i)   above   have   been   honored.    All   requests   for

distributions in reduction of the Certificate   Principal   Balance of the Insured

Certificates   will be accepted in accordance   with the   provisions   set forth in

Section 4.10(c).   All requests for distributions in reduction of the Certificate

Principal   Balance of the Insured   Certificates with respect to any Distribution
