                                             PRELIMINARY STATEMENT

               The  Depositor  is the  owner of the  Trust  Fund  (other  than the  Trust's  rights  under  the
Group 5 Interest  Rate Cap Agreement)  that is hereby  conveyed to the Trustee in return for the  Certificates.
The Trust Fund (exclusive of any entitlement to Assigned  Prepayment  Premiums,  the Group 5  Interest Rate Cap
Agreement and the assets held in the Group 5  Interest Rate Cap Account) for federal  income tax purposes shall
consist of three REMICs (referred to as "REMIC I," "REMIC II" and "REMIC III").

                                                    REMIC I

        As provided  herein,  the Trust  Administrator  will make an election to treat the  segregated  pool of
assets  consisting  of the Group 1,  Group 2,  Group 3 and Group 4  Mortgage  Loans and certain  other  related
assets  (exclusive of any  entitlement  to Assigned  Prepayment  Premiums)  subject to this Agreement 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."  Component I  of the  Class AR-L  Certificates  will represent the sole
Class of  "residual  interests"  in REMIC I for  purposes of the REMIC  Provisions  (as defined  herein)  under
federal  income tax law. The following  table  irrevocably  sets forth the  designation,  remittance  rate (the

Component I  of the  Class AR-L  Certificates.  The "latest  possible  maturity  date"  (determined  solely for
purposes of satisfying  Treasury  regulation  Section 1.860G-1(a)(4)(iii))  for each REMIC I  Regular  Interest
shall be the Maturity Date.  None of the REMIC I Regular Interests will be certificated.

(13)    The Class 5-X  Certificates  will not accrue interest on their Class Principal  Balance.  The Class 5-X

    regular interest designated 5-X-PO and an interest only regular interest  designated 5-X-IO,  which will be
    entitled to  distributions  as set forth herein.  On each  Distribution  Date,  the Class 5-X  Certificates
    shall be entitled to the Class 5-X  Distributable  Amount.  With respect to any Distribution Date, interest
    accrued on the  Class 5-X  Certificates  during the related  Accrual  Period  shall  equal  interest at the
    related  Pass-Through Rate on the Class 5-X  Notional Amount  immediately prior to such Distribution  Date,

    days in the  related  Accrual  Period and  (b) the  aggregate  principal  balance of the  REMIC II  Regular
    Interests  LT1,  LT2, LT3 and LT4. For purposes of  calculating  the  Pass-Through  Rate for the  Class 5-X
    Certificates, the numerator is equal to the sum of the following components:
        (i)the  Uncertificated  Pass-Through  Rate for REMIC II  Regular  Interests  LT1 minus the Marker Rate,
           applied to a notional  amount equal to the aggregate  Uncertificated  Principal  Balance of REMIC II
           Regular Interests LT1;
        (ii)   the  Uncertificated  Pass-Through  Rate for REMIC II Regular Interest LT2 minus the Marker Rate,
           applied to a notional  amount  equal to the  Uncertificated  Principal  Balance of REMIC II  Regular
           Interest LT2; and
        (iii)  the  Uncertificated  Pass-Through  Rate for REMIC II Regular Interest LT4 minus twice the Marker
           Rate,  applied  to a notional  amount  equal to the  Uncertificated  Principal  Balance of  REMIC II
           Regular Interest LT4.
    Accrued interest on the Class 5-X  Certificates  shall accrue on the basis of a 360-day year and the actual
    number of days in the related  Accrual  Period.  Payments to any Class of  Group 5  Certificates in respect
    of Basis Risk  Shortfalls  from the Group 5  Available  Distribution  Amount  shall be deemed to have first
    been  distributed  from  REMIC III  to  the  holders  of  the  Class 5-X  Certificates  in  respect  of the
    Class 5-X-IO  REMIC III  Regular  Interest  and  then  paid  by  such  holders  to  such  Class of  Group 5
    Certificates.
(15)    The  Class 5-X  Certificates  will  be  issued  in  certificated,   fully-registered  form  in  minimum
    denominations of 20% of the Percentage Interest therein and increments of 10% in excess thereof.
(16)    The Class P  Certificates will not have a Class Principal Balance.  The Class P Certificates shall have
    an initial  notional  balance of  $1,027,817,280.53  and will be  entitled  to  distributions  of  Assigned
    Prepayment Premiums only.  Such entitlement shall not be an interest in any REMIC created hereunder.
(17)    The  Class P   Certificates  will  be  issued  in  certificated,   fully-registered   form  in  minimum
    denominations of 20% of the Percentage Interest therein and increments of 10% in excess thereof.
(18)    The Class AR Certificates are issued in minimum Percentage Interests of 20%.

               For the avoidance of doubt,  the Trust  Administrator  shall account for any interest amount due
to a  Certificateholder  in excess of the  interest  rate on the REMIC  Regular  Interest  issued by  REMIC III
corresponding to such Certificate as part of the payment made to the Class 5-X  Certificates,  to the extent it
is  entitled to funds from the REMIC,  and then paid  outside of the REMIC  pursuant to a separate  contractual
right to such Certificateholder.

               The foregoing  REMIC  structure is intended to cause all of the cash from the Mortgage  Loans to
flow through to REMIC III as cash flow on a REMIC Regular Interest,  without creating any  shortfall-actual  or
potential  (other than for credit  losses) to any REMIC Regular  Interest.  To the extent that the structure is
believed to diverge from such intention the Trust  Administrator  shall resolve  ambiguities to accomplish such
result and shall to the extent  necessary  rectify any drafting errors or seek  clarification  to the structure
without Certificateholder approval (but with guidance of counsel) to accomplish such intention.

               REMIC II  Principal  Reduction  Amounts:  For any  Distribution  Date,  the amounts by which the
principal  balances of the REMIC II Regular Interests LT1, LT2, LT3 and LT4,  respectively,  will be reduced on
such  Distribution  Date by the allocation of Realized Losses and the distribution of principal,  determined as
follows:

        For purposes of the succeeding formulas the following symbols shall have the meanings set forth below:

        Y1 =   the aggregate  principal  balance of the REMIC II Regular  Interests LT1 after  distributions on
the prior Distribution Date.

        Y2 =   the principal  balance of the REMIC II  Regular  Interest LT2 after  distributions  on the prior
Distribution Date.

        Y3 =   the principal  balance of the REMIC II  Regular  Interest LT3 after  distributions  on the prior
Distribution Date.

        Y4 =   the principal  balance of the REMIC II  Regular  Interest LT4 after  distributions  on the prior
Distribution Date (note:  Y3 = Y4).

        ΔY1 =  the combined REMIC II Regular Interests LT1 Principal Reduction Amount.

        ΔY2 =  the REMIC II Regular Interest LT2 Principal Reduction Amount.

        ΔY3 =  the REMIC II Regular Interest LT3 Principal Reduction Amount.

        ΔY4 =  the REMIC II Regular Interest LT4 Principal Reduction Amount.

        P0 =   the aggregate  principal  balance of the REMIC II Regular  Interests LT1, LT2, LT3 and LT4 after
distributions and the allocation of Realized Losses on the prior Distribution Date.

        P1 =   the aggregate  principal  balance of the REMIC II Regular  Interests LT1, LT2, LT3 and LT4 after
distributions and the allocation of Realized Losses to be made on such Distribution Date.

        ΔP =   P0 - P1 = the  aggregate of the  REMIC II  Regular  Interests  LT1,  LT2, LT3 and LT4  Principal
Reduction Amounts.

              =the  aggregate  of the  principal  portions  of  Realized  Losses to be  allocated  to,  and the
principal  distributions  to be made  on,  the  Group I  Certificates  on  such  Distribution  Date  (including
distributions of accrued and unpaid interest on the Class SB-I Certificates for prior Distribution Dates).

        R0 =   the Group 5 Net WAC Rate (stated as a monthly rate) after giving  effect to amounts  distributed
and Realized Losses allocated on the prior Distribution Date.

        R1 =   the  Group 5  Net WAC Rate  (stated  as a monthly  rate)  after  giving  effect to amounts to be
distributed and Realized Losses to be allocated on such Distribution Date.

        α =    (Y2 + Y3)/P0.  The  initial  value of α on the  Closing  Date for use on the first  Distribution
Date shall be 0.0001.

        γ0 =   the lesser of (A) the sum for all  Classes of Group 5  LIBOR  Certificates  of the  product  for
each  Class of  (i) the  monthly  interest  rate (as  limited by the Net Funds  Cap,  if  applicable)  for such
Class applicable  for  distributions to be made on such Distribution  Date and (ii) the  aggregate  Certificate
Principal  Balance for such  Class after  distributions  and the  allocation  of  Realized  Losses on the prior
Distribution Date and (B) R0*P0.

        γ1  =  the lesser of (A) the sum for all  Classes  of  Group 5  Certificates  of the  product  for each
Class of  (i) the  monthly  interest  rate  (as  limited  by  the  Net  Funds  Cap,  if  applicable)  for  such
Class applicable  for distributions to be made on the next succeeding  Distribution Date and (ii) the aggregate
Certificate  Principal  Balance for such Class after  distributions and the allocation of Realized Losses to be
made on such Distribution Date and (B) R1*P1.

        Then, based on the foregoing definitions:

        ΔY1 =  ΔP - ΔY2 - ΔY3 - ΔY4;

        ΔY2 =  (α/2){( γ0R1 - γ1R0)/R0R1};

        ΔY3 =  αΔP - ΔY2; and

        ΔY4 =  ΔY3.

        if both ΔY2 and ΔY3, as so determined, are non-negative numbers.  Otherwise:

        (1)    If ΔY2, as so determined, is negative, then

        ΔY2 = 0;

        ΔY3 = α{γ1R0P0 - γ0R1P1}/{γ1R0};

        ΔY4 = ΔY3; and

        ΔY1 = ΔP - ΔY2 - ΔY3 - ΔY4.

        (2)    If ΔY3, as so determined, is negative, then

        ΔY3 = 0;

        ΔY2 = α{γ1R0P0 - γ0R1P1}/{2R1R0P1 -  γ1R0};

        ΔY4 = ΔY3; and

        ΔY1 = ΔP - ΔY2 - ΔY3 - ΔY4.

The Principal Reduction Amount ΔY1 shall be allocated to the REMIC II Regular Interest LT1.

               REMIC II  Realized  Losses:  Realized  Losses on the  Group 5  Mortgage  Loans  for the  related
Collection  Period shall be allocated to the REMIC II Regular  Interests LT1, LT2, LT3 and LT4, in reduction of
the principal balances thereof and interest accrued thereon,  as follows:  (i) the interest portion of Realized
Losses,  if any, shall be allocated pro rata to accrued  interest on the REMIC II  Regular  Interests LT1, LT2,
LT3 and LT4, to the extent of such accrued  interest,  and  (ii) any  remaining  interest  portions of Realized
Losses and any  principal  portions  of  Realized  Losses  shall be treated as  principal  portions of Realized
Losses and allocated  (i) to the REMIC II  Regular  Interest LT2,  REMIC II  Regular  Interest LT3 and REMIC II
Regular  Interest LT4,  pro rata according to their respective Principal Reduction Amounts,  provided that such
allocation to each of the REMIC II  Regular  Interest LT2,  REMIC II  Regular Interest LT3 and REMIC II Regular
Interest LT4 shall not exceed their respective  Principal  Reduction Amounts,  and (ii) any Realized Losses not
allocated to any of the REMIC II  Regular  Interest LT2,  REMIC II  Regular  Interest LT3  and REMIC II Regular
Interest LT4  pursuant  to the  provisos  of clause  (i)  above  shall be  allocated  to the  REMIC II  Regular
Interest LT1,  until the principal  balance  thereof  shall have been reduced to zero.  Any Realized  Losses on
the Group 5 Mortgage Loans remaining after the allocations  made in the preceding  sentences shall be allocated
among  the  Class LT2,  Class LT3  and  Class LT4  REMIC II  Regular  Interests  pro-rata  according  to  their
respective  principal  balances as reduced by the  allocations  in the preceding  sentence until such principal
balances shall have been reduced to zero.

               REMIC II  Regular Interest LT1 Principal  Distribution  Amount:  For any Distribution  Date, the
excess,  if any, of the REMIC II Regular Interest LT1 Principal  Reduction  Amount for such  Distribution  Date

Payments)  relating to the Group 1,  Group 2,  Group 3 and Group 4  Mortgage  Loans for any  Distribution  Date
shall  be  allocated  among  the  REMIC I  Regular  Interests,  pro  rata,  based  on,  and to the  extent  of,
Uncertificated  Accrued  Interest,  as  calculated  without  application  of this  sentence.  For  purposes  of
calculating  the  amount  of  Uncertificated  Accrued  Interest  for the  REMIC II  Regular  Interests  for any
Distribution  Date, any Prepayment  Interest  Shortfalls  (to the extent not covered by  Compensating  Interest
Payments)  relating  to the Group 5  Mortgage  Loans for any  Distribution  Date shall be  allocated  among the
REMIC II Regular  Interests,  pro rata, based on, and to the extent of,  Uncertificated  Accrued  Interest,  as
calculated  without  application of this sentence.  Uncertificated  Accrued  Interest on the REMIC III  Regular
Interest 5-X-PO shall be zero.  Uncertificated  Accrued  Interest on the REMIC III  Regular Interest 5-X-IO for
each Distribution Date shall equal Accrued Certificate Interest for the Class 5-X Certificates.

               Uncertificated  Pass-Through  Rate:  For  any  REMIC I  Regular  Interest  or  REMIC II  Regular
Interest,  the per annum rate set forth or  calculated  in the manner  described in the  Preliminary  Statement

               Uncertificated  Principal  Balance:  The  principal  amount of any REMIC I or  REMIC II  Regular
Interest  outstanding as of any date of  determination.  As of the Closing Date, the  Uncertificated  Principal
Balance of each  REMIC I and  REMIC II  Regular  Interest  shall equal the amount set forth in the  Preliminary
Statement   hereto  as  its  Initial   Uncertificated   Principal   Balance  under  "REMIC I"  and  "REMIC II,"
respectively.  On each  Distribution  Date,  the  Uncertificated  Principal  Balance  of each  REMIC I  Regular
Interest and REMIC II Regular Interest shall be reduced,  in the case of REMIC I Regular Interests,  by the sum
of (i) the  principal  portion of Realized Losses allocated to the REMIC I Regular Interests in accordance with
the definition of REMIC I Realized Losses and (ii) the  amounts deemed  distributed on each  Distribution  Date
in respect of principal on the REMIC I Regular Interests  pursuant to  Section 4.01(IV)(a)(i),  and in the case
of REMIC II  Regular  Interests,  by the sum of (i) the  principal  portion of Realized Losses allocated to the
REMIC II Regular  Interests in accordance with the definition of REMIC II  Realized Losses and (ii) the amounts
deemed  distributed  on each  Distribution  Date in respect of  principal  on the  REMIC II  Regular  Interests
pursuant to Section 4.01(IV)(a)(ii).

               Uncertificated  Regular  Interest:  Any of the REMIC I  Regular  Interests and REMIC II  Regular
Interests.

tax purposes  regardless of its  connection  with the conduct of a trade or business  within the United States,
or any trust treated as a United States Person under Code Section 7701(a)(30).

               Voting  Rights:  The portion of the voting rights of all the  Certificates  that is allocated to
any  Certificate  for  purposes of the voting  provisions  of this  Agreement.  At all times during the term of
this  Agreement,  99% of all Voting Rights shall be allocated  among the Class A  Certificates  (other than the
Residual  Certificates),  Class M  Certificates  and Class C-B  Certificates.  The  portion  of such 99% Voting
Rights  allocated  to  each of the  Class A  Certificates  (other  than  the  Residual  Certificates),  Class M
Certificates  and Class  C-B  Certificates  shall be based on the  fraction,  expressed  as a  percentage,  the
numerator of which is the Class  Principal  Balance of each such Class then  outstanding and the denominator of
which is the aggregate Class Principal  Balance of all such Classes then  outstanding.  At all times during the
term of this Agreement,  the Class 5-X  Certificates shall be allocated 1% of the Voting Rights.  Voting Rights
shall be allocated  among the  Certificates  within each Class in  proportion to their  respective  outstanding
Class Principal  Balances or Class Notional Amounts,  as applicable.  The Class AR and Class AR-L  Certificates
shall have no Voting Rights.

               Weighted  Average  Pass-Through  Rate:  With respect to any  Distribution  Date and Loan Group a
rate equal to the weighted  average of the Net Mortgage  Rates on the Mortgage  Loans in such Loan  Group as of
the second  preceding Due Date (excluding any such Mortgage Loans that were subject to a Payoff,  the principal
of which was  distributed  on the  Distribution  Date  preceding  the current  Distribution  Date) after giving
effect  to  payments  due on such Due Date,  whether  or not  received,  weighted  on the  basis of the  Stated
Principal Balances as of such date.

               In addition,  in connection  with the  assignment of any MERS Mortgage  Loan,  the Seller agrees
that it will cause,  at the Seller's  expense,  the MERS® System to indicate that such Mortgage Loans have been
assigned  by  the  Seller  to  the  Trustee  in  accordance   with  this  Agreement  for  the  benefit  of  the
Certificateholders  by  including  (or  deleting,  in the case of  Mortgage  Loans  which  are  repurchased  or
substituted in accordance  with this  Agreement) the  information  required by the MERS® System to (a) identify
the Trustee and  (b) identify  the series of the  Certificates  issued in connection  with such Mortgage Loans.
The Trustee shall  confirm,  or cause the  Custodian to confirm,  on the Final  Certification  of the Custodian
that  such  assignment  has  occurred.  The  Seller  further  agrees  that it will not,  and will not  permit a
Servicer  to, and each related  Servicer  agrees that it will not,  alter the  information  referenced  in this
paragraph  with respect to any Mortgage Loan during the term of this  Agreement  unless and until such Mortgage
Loan is repurchased or substituted in accordance with the terms of this Agreement.

               In the event the  Depositor  delivers  to the  Custodian  certified  copies of any  document  or
instrument  set forth in  2.01(b) because  of a delay caused by the public  recording  office in returning  any
recorded  document,  the Depositor  shall deliver or cause to be delivered to the Custodian,  within 60 days of
the Closing Date, an Officer's  Certificate  which shall  (i) identify the recorded  document,  (ii) state that
the  recorded  document  has not been  delivered  to the  Custodian  due solely to a delay caused by the public
recording office, and (iii) state the amount of time generally  required by the applicable  recording office to
record and return a document submitted for recordation.

               In the event that in connection  with any Mortgage Loan the Depositor  cannot deliver  (a) for a
Mortgage Loan that is not a MERS Mortgage  Loan,  the original  recorded  Mortgage,  (b) all  interim  recorded
assignments or (c) the  lender's title policy  (together with all riders thereto)  satisfying the  requirements
set forth above,  concurrently  with the execution and delivery  hereof because such document or documents have
not been returned from the  applicable  public  recording  office in the case of clause  (a) or  (b) above,  or
because  the title  policy  has not been  delivered  to the Seller or the  Depositor  by the  applicable  title
insurer in the case of clause  (c) above,  the Depositor shall promptly  deliver to the Custodian,  in the case
of clause  (a) or  (b) above,  such  original  Mortgage or such  interim  assignment,  as the case may be, with
evidence of recording  indicated  thereon upon receipt  thereof  from the public  recording  office,  or a copy
thereof,  certified,  if appropriate,  by the relevant  recording office and, in the case of clause  (c) above,
any title policy upon receipt from the applicable title insurer.

               As promptly as practicable subsequent to such transfer and assignment,  and in any event, within
thirty (30) days thereafter,  DLJMC shall, at its expense,  (i) affix or cause to be affixed the Trustee's name
to each Assignment of Mortgage,  as the assignee  thereof,  (ii) cause such assignment to be in proper form for
recording in the  appropriate  public  office for real property  records  within thirty (30) days after receipt
thereof and  (iii) cause  to be delivered  for  recording in the  appropriate  public  office for real property
records the  assignments  of the  Mortgages to the Trustee,  except that,  with respect to any  assignment of a
Mortgage as to which DLJMC has not received the  information  required to prepare such assignment in recordable
form,  DLJMC's  obligation to do so and to deliver the same for such recording  shall be as soon as practicable
after  receipt of such  information  and in any event within  thirty (30) days after the receipt  thereof,  and
DLJMC need not cause to be recorded any assignment which relates to a Mortgage Loan in any  jurisdiction  under
the laws of which,  as  evidenced  by an Opinion of Counsel  delivered  by the  Depositor  (at the  Depositor's
expense)  to the  Trustee,  the  Trust  Administrator  and  DLJMC,  acceptable  to  the  Rating  Agencies,  the
recordation of such assignment is not necessary to protect the Trustee's and the  Certificateholders'  interest
in the related Mortgage Loan.

               If any original  Mortgage Note referred to in  Section 2.01(b)(i) above  cannot be located,  the
obligations  of the Depositor to deliver such  documents  shall be deemed to be satisfied  upon delivery to the
Custodian of a photocopy of such Mortgage  Note, if available,  with a lost note  affidavit and  indemnity.  If
any of the  original  Mortgage  Notes  for which a lost note  affidavit  and  indemnity  was  delivered  to the
Custodian is  subsequently  located,  such original  Mortgage  Note shall be delivered to the Custodian  within
three (3) Business Days.

(c)     The Trustee and the Trust Administrator are authorized to enter into one or more Custodial  Agreements,
at the  direction of the  Depositor,  for the purpose of having a Custodian  maintain  custody of the documents
and instruments  referred to in this Section 2.01,  and any documents  delivered  thereunder shall be delivered
to the  Custodian  and any  Officer's  Certificates  delivered  with respect  thereto shall be delivered to the
Trustee, the Trust Administrator and the Custodian.

(d)     It is the express  intent of the parties to this Agreement that the conveyance of the Mortgage Loans by
the Depositor to the Trustee as provided in this  Section 2.01  be, and be construed as, a sale of the Mortgage
Loans by the  Depositor to the Trustee.  It is,  further,  not the  intention of the parties to this  Agreement
that such  conveyance  be deemed a pledge of the  Mortgage  Loans by the  Depositor  to the Trustee to secure a
debt or other  obligation  of the  Depositor.  However,  in the event that,  notwithstanding  the intent of the
parties to this Agreement,  the Mortgage Loans are held to be the property of the Depositor,  or if any for any
other  reason  this  Agreement  is held or deemed to create a  security  interest  in the  Mortgage  Loans then
(a) this  Agreement shall also be deemed to be a security  agreement  within the meaning of Articles 8 and 9 of
the New York Uniform Commercial Code;  (b) the conveyance  provided for in this Section 2.01 shall be deemed to
be a grant by the  Depositor to the Trustee for the benefit of the  Certificateholders  of a security  interest
in all of the  Depositor's  right,  title and interest in and to (1) the Mortgage  Loans listed in the Mortgage
Loan  Schedule,  including  all interest  and  principal  received or  receivable  by the  Depositor on or with
respect to the  Mortgage  Loans  after the related  Cut-off  Date and any  Assigned  Prepayment  Premiums  with
respect  thereto,  but not including  payments of principal and interest due and payable on the Mortgage  Loans
on or before the related  Cut-off  Date,  together  with the Mortgage  Files  relating to the  Mortgage  Loans,
(2) REO Property,  (3) the Collection Account,  the Certificate  Account, the Group 5 Interest Rate Cap Account
and all amounts  deposited therein pursuant to the applicable  provisions of this Agreement,  (4) any insurance
policies with respect to the Mortgage  Loans,  (5) the  Depositor's  rights under the Assignment and Assumption
Agreement and (6) all proceeds of the conversion,  voluntary or involuntary,  of any of the foregoing into cash
or other liquid  property;  (c) the  possession  by the Trustee or any  Custodian of such items of property and
such other items of property as constitute  instruments,  money, negotiable documents or chattel paper shall be
deemed to be "in  possession by the secured party" for purposes of perfecting  the security  interest  pursuant
to  Section 9-313  of the New York Uniform  Commercial  Code;  and  (d) notifications  to persons  holding such
property,  and acknowledgments,  receipts or confirmations from persons holding such property,  shall be deemed
notifications to, or acknowledgments,  receipts or confirmations  from,  financial  intermediaries,  bailees or
agents (as applicable) of the Trustee for the benefit of the  Certificateholders  for the purpose of perfecting
such security  interest under  applicable law (except that nothing in this clause (d) shall cause any person to
be deemed to be an agent of the Trustee for any purpose other than for  perfection  of such security  interests
unless,  and then only to the extent,  expressly  appointed  and  authorized  by the Trustee in  writing).  The
Depositor and the Trustee,  upon  directions  from the Depositor,  shall,  to the extent  consistent  with this
Agreement,  take such actions as may be necessary to ensure  that,  if this  Agreement  were deemed to create a
security  interest in the Mortgage  Loans,  such security  interest would be deemed to be a perfected  security
interest of first  priority  under  applicable  law and will be maintained as such  throughout the term of this
Agreement.

(e)     The Depositor  hereby  authorizes and directs the Trustee to (i) execute the Group 5  Interest Rate Cap
Agreement and (ii) to  ratify,  on behalf of the Trust,  the terms agreed to by the  Depositor  with respect to
the Group 5  Interest Rate Cap  Agreement.  The Depositor  shall pay or cause to be paid on behalf of the Trust
the payments owed to the Group 5  Interest Rate Cap  Counterparty  as of the Closing Date pursuant to the terms
of the Group 5 Interest Rate Cap Agreement.

(f)     Except as specifically set forth in this Agreement or by separate  written  agreement among the related
parties hereto, the Depositor,  the Seller,  each Servicer and the Master Servicer agree that the provisions of
this Agreement  shall  supercede any provisions in any existing  mortgage loan purchase  agreement or servicing
agreement  with respect to the Mortgage  Loans for which the  Depositor,  the Seller,  a Servicer or the Master
Servicer may be a party.

SECTION 2.02.  Acceptance by the Trustee.

(a)     Pursuant to Section 4 of the LaSalle Custodial  Agreement,  the Custodian agrees to execute and deliver
on the Closing  Date to the  Depositor,  the Trustee and the Trust  Administrator  a Trust  Receipt and Initial
Certification  in the form annexed  hereto as Exhibit I.  Based on its review and  examination,  and only as to
the documents  identified  in such Trust Receipt and Initial  Certification,  the Custodian  acknowledges  that
such documents  appear  regular on their face and relate to such Mortgage  Loan.  The Custodian  shall be under
no duty or obligation to inspect, review or examine said documents,  instruments,  certificates or other papers
to determine that the same are genuine,  enforceable or appropriate  for the  represented  purpose or that they
have actually  been recorded in the real estate  records or that they are other than what they purport to be on
their face.

               Pursuant to  Section 6  of the  LaSalle  Custodial  Agreement,  not later than 90 days after the
Closing Date, the Custodian  shall deliver to the Depositor,  the Trustee and the Trust  Administrator  a Trust
Receipt and Final Certification in the form annexed hereto as Exhibit J,  with any applicable  exceptions noted
thereon.

               Based solely upon the Trust Receipt and Initial Certification  received from the Custodian,  and
subject to the provisions of Section 2.01  and any exceptions  noted on the exception  report  described in the
next paragraph below, the Trustee  acknowledges  receipt of the documents referred to in Section 2.01 above and
declares that it holds and will hold such documents and the other documents  delivered to it  constituting  the
Mortgage  File,  and  that it holds  or will  hold all such  assets  and  such  other  assets  included  in the
definition  of the  Trust  Fund  in  trust  for the  exclusive  use  and  benefit  of all  present  and  future
Certificateholders.

               If, in the course of such review,  the  Custodian  finds any document  constituting  a part of a
Mortgage  File  which does not meet the  requirements  of  Section 2.01,  the  Custodian  shall list such as an
exception  in the Trust  Receipt  and Final  Certification  pursuant  to  Section 6  of the  LaSalle  Custodial
Agreement;  provided,  however,  that the  Custodian  shall not make any  determination  as to whether  (i) any
endorsement  is sufficient to transfer all right,  title and interest of the party so endorsing,  as noteholder
or  assignee  thereof,  in and to that  Mortgage  Note  or  (ii) any  assignment  is in  recordable  form or is
sufficient  to effect the  assignment  of and transfer to the assignee  thereof under the mortgage to which the
assignment relates.

               The Seller  shall  promptly  correct or cure such defect  within 90 days from the date it was so
notified of such  defect  and,  if the Seller does not correct or cure such defect  within such period and such
defect materially and adversely affects the interests of  Certificateholders  in the related Mortgage Loan, the
Seller shall either  (a) substitute for the related Mortgage Loan a Qualified  Substitute  Mortgage Loan, which
substitution  shall be accomplished in the manner and subject to the conditions set forth in  Section 2.03,  or
(b) repurchase  such  Mortgage Loan within 90 days from the date that the Seller was notified of such defect in
writing at the Purchase  Price of such  Mortgage  Loan;  or such longer  period not to exceed 720 days from the
Closing Date if the  substitution  or repurchase  of a Mortgage Loan pursuant to this  provision is required by
reason of a delay in delivery  of any  documents  by the  appropriate  recording  office or title  insurer,  as
applicable;  provided,  however,  that the Seller shall have no  liability  for  recording  any  Assignment  of
Mortgage in favor of the Trustee or for the  Custodian's  failure to record such  Assignment  of Mortgage,  and
provided,  further,  that no Seller  shall be  obligated to  repurchase  or cure any Mortgage  Loan solely as a
result of the  Custodian's  failure to record  such  Assignment  of  Mortgage.  The Trust  Administrator  shall
deliver or direct the  Custodian to deliver to each Rating  Agency  written  notice  within  270 days  from the
Closing Date  indicating  each Mortgage Loan (a) for which a mortgage or assignment of mortgage  required to be
recorded  hereunder has not been  returned by the  appropriate  recording  office or (b) as to which there is a
dispute  as to  location  or status  of such  Mortgage  Loan.  Such  notice  shall be  delivered  every 90 days
thereafter  until the related  Mortgage Loan is returned to the Custodian.  Any such  substitution  pursuant to
clause (a) of the preceding  sentence  shall not be effected prior to the delivery to the Trustee and the Trust
Administrator  of (1) the Opinion of Counsel  required by  Section 2.05  hereof,  and (2) a Request for Release
substantially  in the form of Exhibit K.  No substitution  is permitted to be made in any calendar  month after
the  Determination  Date for such month.  The Purchase  Price for any such  Mortgage Loan shall be deposited by
the Seller in the  related  Collection  Account on or prior to the  Business  Day  immediately  preceding  such
Distribution  Date in the month  following  the month during  which the Seller  became  obligated  hereunder to
repurchase  or replace such  Mortgage  Loan and,  upon receipt of such deposit and  certification  with respect
thereto in the form of Exhibit K  hereto,  the Custodian shall release the related  Mortgage File to the Seller
and shall execute and deliver at such entity's request such  instruments of transfer or assignment  prepared by
such entity,  in each case without recourse,  as shall be necessary to vest in such entity, or a designee,  the
Trustee's interest in any Mortgage Loan released pursuant hereto.

               If pursuant to the  preceding  paragraph  the Seller  repurchases a Mortgage Loan that is a MERS
Mortgage  Loan, the related  Servicer  shall,  at the Seller's  expense,  either  (i) cause MERS to execute and
deliver an  Assignment  of Mortgage in  recordable  form to transfer the  Mortgage  from MERS to the Seller and
shall cause such Mortgage to be removed from  registration  on the MERS® System in accordance  with MERS' rules
and  regulations  or (ii) cause  MERS to designate on the MERS® System the Seller as the  beneficial  holder of
such Mortgage Loan.

(b)     It is understood and agreed that the obligation of the Seller to cure,  substitute for or to repurchase
any  Mortgage  Loan which does not meet the  requirements  of  Section 2.01  shall  constitute  the sole remedy
respecting  such  defect  available  to  the  Trustee,   the  Trust   Administrator,   the  Depositor  and  any
Certificateholder against the Seller.

(c)     With  respect to any  Mortgage  Loan which  becomes  delinquent  in payment by 90 days or more or is an
REO Property,  DLJMC shall have the right to  repurchase  such Mortgage Loan from the Trust at a price equal to
the Purchase Price;  provided,  however,  that (i) such Mortgage Loan is still 90 days or more delinquent or is
an  REO Property  as of the  date of such  repurchase  and  (ii) this  repurchase  option,  if not  theretofore
exercised,  shall  terminate on the date at the close of business on the 90th day after the Mortgage Loan is 90
days  delinquent  or the  Mortgage  Loan becomes an  REO Property;  provided,  further,  that in no event shall
repurchases  pursuant to this paragraph take place with respect to Mortgage Loans  constituting more than 5% of
the  aggregate  Cut-off Date  Principal  Balance of the Mortgage  Loans.  This  repurchase  obligation,  if not
exercised,  shall  not be  thereafter  reinstated  unless  the  delinquency  is  cured  and the  Mortgage  Loan
thereafter  again becomes 90 days delinquent or becomes an  REO Property,  in which case the option shall again
become  exercisable  as of the first day the  Mortgage  Loan becomes 90 days or more  delinquent  or becomes an
REO Property.

               In the event that DLJMC  exercises  such option,  the Purchase Price therefor shall be deposited
in the related  Collection  Account and upon such  deposit of the  Purchase  Price and receipt of a Request for
Release in the form of Exhibit K hereto,  the Custodian  shall  release the related  Mortgage File held for the
benefit of the  Certificateholders  to DLJMC,  and the Trustee shall  execute and deliver at DLJMC's  direction
such  instruments  of transfer or  assignment  prepared by DLJMC,  in each case without  recourse,  as shall be
necessary to transfer title from the Trustee to DLJMC.

SECTION 2.03.   Representations and Warranties of the Seller, Master Servicer and Servicers.

(a)     Each of DLJMC, in its capacity as Seller, Wells Fargo, in its capacity as Master Servicer,  SPS, in its
capacity as Servicer  and Special  Servicer,  Wells  Fargo,  in its  capacity  as  Servicer,  JPMorgan,  in its
capacity as Servicer,  and Ocwen, in its capacity as Servicer,  hereby makes the representations and warranties
applicable to it set forth in Schedules  IIA, IIB,  IIC,  IID, IIE or IIF, as  applicable  hereto,  and by this
reference  incorporated herein, to the Depositor,  the Trustee and the Trust  Administrator,  as of the Closing
Date,  or if so  specified  therein,  as of the  Cut-off  Date  or such  other  date  as may be  specified.  In
addition,  SPS, in its capacity as Servicer  and Special  Servicer,  Wells Fargo,  in its capacity as Servicer,
JPMorgan,  in its capacity as Servicer,  and Ocwen, in its capacity as Servicer,  makes the representations and
warranties  applicable  to it set forth in Schedules  IIC, IID, IIE and IIF hereto,  respectively,  and by this
reference  incorporated  herein, to the Master Servicer as of the Closing Date, or if so specified therein,  as
of the Cut-off Date or such other date as may be specified.

(b)     DLJMC,  in its  capacity  as Seller,  hereby  makes the  representations  and  warranties  set forth in
Schedule  III as to the  Mortgage  Loans and by this  reference  incorporated  herein,  to the  Depositor,  the
Trustee and the Trust  Administrator,  as of the Closing  Date, or if so specified  therein,  as of the Cut-off
Date or such other date as may be specified.

(c)     Upon discovery by any of the parties hereto of a breach of a  representation  or warranty made pursuant
to  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 notice thereof to the other parties.  The
Seller hereby  covenants  that within 90 days of the earlier of its discovery or its receipt of written  notice
from any party of a breach of any  representation  or warranty  made by it  pursuant  to  Section 2.03(b) which
materially  and  adversely  affects the  interests of the  Certificateholders  in any Mortgage Loan sold by the
Seller to the Trust,  it shall cure such breach in all material  respects,  and if such breach is not so cured,
shall,  (i) if such 90 day period  expires prior to the second  anniversary  of the Closing  Date,  remove such
Mortgage  Loan (a  "Deleted  Mortgage  Loan")  from the Trust  Fund and  substitute  in its  place a  Qualified
Substitute  Mortgage  Loan,  in the  manner  and  subject  to the  conditions  set  forth in this  Section;  or
(ii) repurchase  the affected  Mortgage  Loan or Mortgage  Loans at the Purchase  Price in the manner set forth
below;  provided,  however, that any such substitution pursuant to (i) above shall not be effected prior to the
delivery  to the  Trustee  and the Trust  Administrator  of the  Opinion of Counsel  required  by  Section 2.05
hereof, if any, and any such  substitution  pursuant to (i) above shall not be effected prior to the additional
delivery  to the Trustee or the Trust  Administrator  of a Request  for  Release  substantially  in the form of
Exhibit K  relating  to the Deleted  Mortgage  Loan and the  Mortgage  File for any such  Qualified  Substitute
Mortgage Loan. The Seller shall promptly reimburse the Trustee, the Trust  Administrator,  the Special Servicer
and the  related  Servicer  (if such  Servicer is not the Seller of such  Mortgage  Loan) for any actual out of
pocket expenses  reasonably  incurred by the Trustee,  the Trust  Administrator,  the Special  Servicer and the
related  Servicer  (if such  Servicer  is not the Seller of such  Mortgage  Loan) in respect of  enforcing  the
remedies for such breach.  With respect to any  representation  and warranties  described in this Section which
are  made to the best of the  Seller's  knowledge  if it is  discovered  by any of the  Depositor,  the  Master
Servicer,  the Seller,  any Servicer,  the Special Servicer,  the Trustee or the Trust  Administrator  that the
substance of such  representation  and warranty is  inaccurate  and such  inaccuracy  materially  and adversely
affects  the  value  of  the  related  Mortgage  Loan  or the  interests  of  the  Certificateholders  therein,
notwithstanding  the  Seller's  lack of  knowledge  with respect to the  substance  of such  representation  or
warranty, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

               With respect to any Qualified  Substitute  Mortgage  Loan or Loans,  the Seller shall deliver to
the  Custodian  for the  benefit of the  Certificateholders  the  Mortgage  Note,  the  Mortgage,  the  related
assignment of the Mortgage,  and such other documents and agreements as are required by  Section 2.01(b),  with
the  Mortgage  Note  endorsed  and the  Mortgage  assigned as  required by  Section 2.01.  No  substitution  is
permitted to be made in any calendar  month after the  Determination  Date for such month.  Scheduled  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 Seller on the next  succeeding  Distribution  Date.  For the month of
substitution,  distributions  to  Certificateholders  will  include  the  monthly  payment  due on any  Deleted
Mortgage  Loan for such month and  thereafter  the Seller  shall be entitled to retain all amounts  received in
respect of such Deleted  Mortgage  Loan.  The Seller shall amend the Mortgage  Loan Schedule 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 Seller shall  deliver the amended  Mortgage Loan Schedule
to the Trustee,  the Servicers and the Trust  Administrator.  Upon such substitution,  the Qualified Substitute
Mortgage Loan or Loans shall be subject to the terms of this  Agreement in all  respects,  and the Seller shall
be deemed to have made with respect to such  Qualified  Substitute  Mortgage  Loan or Loans,  as of the date of
substitution,  the  representations  and  warranties  made  pursuant  to  Section 2.03(b) with  respect to such
Mortgage Loan.  Upon any such  substitution  and the deposit to the Collection  Account of the amount  required
to be deposited  therein in connection  with such  substitution  as described in the following  paragraph,  the
Trustee   shall   instruct  the   Custodian  to  release  the  Mortgage  File  held  for  the  benefit  of  the
Certificateholders  relating to such  Deleted  Mortgage  Loan to the Seller and the Trustee  shall  execute and
deliver at the Seller's  direction such instruments of transfer or assignment  prepared by the Seller,  in each
case without  recourse,  as shall be  necessary to vest title in the Seller,  or its  designee,  the  Trustee's
interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

               For any month in which the Seller  substitutes one or more Qualified  Substitute  Mortgage Loans
for one or more Deleted  Mortgage  Loans,  the Master Servicer shall 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 (after  application of the
scheduled  principal  portion of the monthly  payments  due in the month of  substitution).  The amount of such
shortage (the  "Substitution  Adjustment  Amount")  plus an amount equal to the  aggregate of any  unreimbursed
Advances,  Servicing  Advances and unpaid  Servicing Fees with respect to such Deleted  Mortgage Loans shall be
deposited in the related Collection  Account by the Seller on or before the Business Day immediately  preceding
the  Distribution  Date in the month  succeeding  the calendar  month during  which the related  Mortgage  Loan
became required to be repurchased or replaced hereunder.

               One or more  mortgage  loans may be  substituted  for one or more Deleted  Mortgage  Loans.  The
determination  of whether a mortgage  loan is a  Qualified  Substitute  Mortgage  Loan may be  satisfied  on an
individual  basis.  Alternatively,  if more than one mortgage loan is to be substituted for one or more Deleted
Mortgage Loans,  the  characteristics  of such mortgage loans and Deleted Mortgage Loans shall be aggregated or
calculated  on a weighted  average  basis,  as  applicable,  in  determining  whether such  mortgage  loans are
Qualified Substitute Mortgage Loans.

               In the event that the Seller shall be required to  repurchase a Mortgage  Loan  pursuant to this
Agreement,  the Purchase Price therefor shall be deposited in the related  Collection  Account on or before the
Business Day  immediately  preceding the  Distribution  Date in the month  following the month during which the
Seller  became  obligated  hereunder to  repurchase  or replace such Mortgage Loan and upon such deposit of the
Purchase  Price and receipt of a Request for  Release in the form of  Exhibit K  hereto,  the  Custodian  shall
release the  related  Mortgage  File held for the benefit of the  Certificateholders  to such  Person,  and the
Trustee  shall  execute and deliver at such  Person's  direction  such  instruments  of transfer or  assignment
prepared by such Person,  in each case  without  recourse,  as shall be  necessary  to transfer  title from the
Trustee.  It is  understood  and  agreed  that the  obligation  under  this  Agreement  of any  Person to cure,
repurchase  or  substitute  any  Mortgage  Loan as to which a  breach  has  occurred  and is  continuing  shall
constitute the sole remedy against such Persons  respecting such breach  available to  Certificateholders,  the
Depositor, the Trustee or the Trust Administrator on their behalf.

               The  representations and warranties made pursuant to this Section 2.03 shall survive delivery of
the respective  Mortgage Files to the Trustee,  the Trust Administrator or the Custodian for the benefit of the
Certificateholders.

SECTION 2.04.  Representations and Warranties of the Depositor as to the Mortgage Loans.

               The Depositor  hereby  represents and warrants to the Trustee with respect to the Mortgage Loans
that, as of the Closing Date,  assuming good title has been conveyed to the  Depositor,  the Depositor had good
title to the Mortgage  Loans and Mortgage  Notes,  and did not encumber the Mortgage Loans during its period of
ownership thereof, other than as contemplated by the Agreement.

               It is  understood  and  agreed  that  the  representations  and  warranties  set  forth  in this
Section 2.04 shall survive delivery of the Mortgage Files to the Custodian.

SECTION 2.05.  Delivery of Opinion of Counsel in Connection with Substitutions.

               Notwithstanding  any  contrary  provision  of  this  Agreement,   no  substitution  pursuant  to
Section 2.02  shall be made more than ninety (90) days after the Closing Date unless the Seller delivers to the
Trustee  and the Trust  Administrator  an  Opinion of  Counsel,  which  Opinion of Counsel  shall not be at the
expense of any of the  Trustee,  the Trust  Administrator  or the Trust Fund,  addressed to the Trustee and the
Trust  Administrator,  to the effect that such substitution will not (i) result in the imposition of the tax on
"prohibited  transactions"  on the Trust Fund or  contributions  after the Startup Date, as defined in Sections
860F(a)(2)  and  860G(d) of  the Code,  respectively,  or (ii) cause  each REMIC  created  hereunder to fail to
qualify as a REMIC at any time that any  Certificates are outstanding;  provided,  however,  that no Opinion of
Counsel  shall be  required if (A) the  substitution  occurs  within two years of the Closing  Date and (B) the
substitution  occurs  with  respect  to  Mortgage  Loans  that are  "defective"  under the Code and the  Seller
delivers to the Trustee and the Trust  Administrator  an  Officer's  Certificate  substantially  in the form of
Exhibit W.

SECTION 2.06.  Issuance of Certificates.

               The  Trustee  acknowledges  the  assignment  to it of  the  Mortgage  Loans  together  with  the
assignment to it of all other assets  included in the Trust Fund,  receipt of which,  subject to the provisions
of  Section 2.02(a),  is hereby  acknowledged.  Concurrently  with such assignment and delivery and in exchange
therefor,  the Trust Administrator,  pursuant to the written request of the Depositor executed by an officer of
the Depositor,  has executed the Certificates and caused them to be authenticated  and delivered to or upon the
order of the Depositor in authorized  denominations  which evidence  ownership of the Trust Fund. The rights of
the Holders of such Certificates to receive  distributions  from the Trust Fund and all ownership  interests of
the Holders of the Certificates in such distributions shall be as set forth in this Agreement.

SECTION 2.07.   REMIC Provisions.

(a)     The  Depositor  hereby elects and  authorizes  the Trust  Administrator  to treat the Trust Fund as the
number of separate  REMICs  specified in the  Preliminary  Statement  (each,  a "REMIC") under the Code and, if
necessary,  under applicable  state law and apply such  Preliminary  Statement in determining the rights of the
Interests  in REMICs  thereby  created.  Each  such  election  will be made on Form  1066 or other  appropriate
federal tax or information  return  (including Form 8811) or any  appropriate  state return (x) for the taxable
year ending on the last day of the calendar year in which the  Certificates  are issued and (y) for the taxable
year ending on the last day of the calendar  year in which  Certificates  are first sold to a third party.  The
Closing Date is hereby  designated as the "startup day" of each REMIC created  hereunder  within the meaning of
Section 860G(a)(9)  of the Code. The "regular  interests"  (within the meaning of  Section 860G of the Code) in
each REMIC shall consist of the regular  interests  with the terms set forth for each REMIC in the  Preliminary
Statement  and the Class AR  and  Class AR-L  Certificates  shall  represent  the  beneficial  ownership of the
"residual  interest" in each REMIC created  hereunder.  Neither the Depositor nor the Trust  Administrator  nor
the Trustee shall permit the creation of any  "interests"  (within the meaning of  Section 860G of the Code) in
any REMIC other than as set forth in the Preliminary Statement.

(b)     The  Trust  Administrator  shall act as the "tax  matters  person"  (within  the  meaning  of the REMIC
Provisions)  for each REMIC created  hereunder,  in the manner  provided  under  Treasury  regulations  section
1.860F 4(d) and  temporary Treasury  regulations  section  301.6231(a)(7)1T.  In the event that for any reason,
the Trust  Administrator is not recognized as the tax matters person then the Trust  Administrator shall act as
agent for the Class AR and the  Class AR-L  Certificateholder  as tax matters  person.  By its  acceptance of a
Residual  Certificate,  each Holder thereof shall have agreed to such  appointment  and shall have consented to
the  appointment  of the Trust  Administrator  as its agent to act on behalf of each  REMIC  created  hereunder
pursuant to the specific duties outlined herein.

(c)     A Holder of the Residual  Certificates,  by the purchase of such Certificates,  shall be deemed to have
agreed to timely  pay,  upon demand by the Trust  Administrator,  the amount of any  minimum  California  state
franchise taxes due with respect to each REMIC created  hereunder under Sections  23151(a) and  23153(a) of the
California  Revenue  and  Taxation  Code.  Notwithstanding  the  foregoing,  the Trust  Administrator  shall be
authorized to retain the amount of such tax from amounts  otherwise  distributable  to such Holder in the event
such Holder does not  promptly  pay such amount upon demand by the Trust  Administrator.  In the event that any
other  federal,  state or local tax is imposed,  including  without  limitation  taxes imposed on a "prohibited
transaction"  of a REMIC as defined in  Section 860F  of the Code,  such tax shall be charged  against  amounts
otherwise  available for  distribution  to the  applicable  Holder of a Residual  Certificate  and then against
amounts  otherwise  available for  distribution  to the Holders of Regular  Certificates in accordance with the
provisions set forth in  Section 4.01.  The Trust  Administrator  or the Trustee shall promptly  deposit in the
Certificate  Account  any  amount  of  "prohibited  transaction"  tax that  results  from a breach of the Trust
Administrator's  or the  Trustee's  duties,  respectively,  under this  Agreement.  The Master  Servicer or the
related Servicer shall promptly deposit in the Certificate  Account any amount of "prohibited  transaction" tax
that  results  from a breach of the Master  Servicer's  or such  Servicer's  duties,  respectively,  under this
Agreement.

(d)     The Trust  Administrator  shall act as  attorney  in fact and as the tax  matters  person of each REMIC
created  hereunder and in such capacity the Trust  Administrator  shall:  (i) prepare,  sign and file, or cause
to be prepared,  signed and filed,  federal and state tax returns using a calendar year as the taxable year for
each REMIC created  hereunder when and as required by the REMIC Provisions and other applicable  federal income
tax laws as the direct  representative  of each such REMIC in compliance with the Code and shall provide copies
of such returns as required by the Code; (ii) make an election,  on behalf of each REMIC created hereunder,  to
be treated as a REMIC on the federal tax return of such REMIC for its first taxable  year,  in accordance  with
the  REMIC  Provisions;  and  (iii) prepare  and  forward,  or  cause  to be  prepared  and  forwarded,  to the
Certificateholders  and to any governmental  taxing  authority all information  reports as and when required to
be provided  to them in  accordance  with the REMIC  Provisions.  The  expenses  of  preparing  and filing such
returns  shall be borne by the  Trust  Administrator.  The  Depositor,  the  Master  Servicer  and the  related
Servicer  shall  provide  on a prompt  and  timely  basis  to the  Trust  Administrator  or its  designee  such
information with respect to each REMIC created  hereunder as is in their possession and reasonably  required or
requested by the Trust Administrator to enable it to perform its obligations under this subsection.

               In its  capacity  as attorney in fact and as the tax  matters  person,  the Trust  Administrator
shall also:  (A) act on behalf of each REMIC  created  hereunder  in relation to any tax matter or  controversy
involving the Trust Fund, (B) represent the Trust Fund in any  administrative or judicial  proceeding  relating
to an examination or audit by any  governmental  taxing authority with respect thereto and (C) cause to be paid
solely from the sources  provided  herein the amount of any taxes imposed on each REMIC created  hereunder when
and as the same shall be due and payable  (but such  obligation  shall not prevent the Trust  Administrator  or
any other  appropriate  Person from  contesting any such tax in appropriate  proceedings  and shall not prevent
the Trust  Administrator  from  withholding  payment of such tax, if permitted  by law,  pending the outcome of
such proceedings).

(e)     The Trust Administrator shall provide (i) to any transferor of a Residual  Certificate such information
as is  necessary  for the  application  of any tax relating to the  transfer of a Residual  Certificate  to any
Person who is not a permitted  transferee,  (ii) to the  Certificateholders  such information or reports as are
required by the Code or the REMIC Provisions  including  reports relating to interest,  original issue discount
and market  discount or premium  and  (iii) to  the  Internal  Revenue  Service  the name,  title,  address and
telephone number of the person who will serve as the representative of each REMIC created hereunder.

(f)     The Trustee,  to the extent  directed by the Trust  Administrator,  the Depositor and the Holder of the
Residual  Certificates  shall take any action or cause the Trust Fund to take any action necessary to create or
maintain  the status of each REMIC  created  hereunder as a REMIC under the REMIC  Provisions  and shall assist
each other as necessary  to create or maintain  such status.  Neither the  Trustee,  to the extent  directed or
(in the case of a failure to act) not  directed  by the Trust  Administrator,  nor the  Holder of the  Residual
Certificates  shall take any action,  cause the Trust Fund to take any action or fail to take (or fail to cause
the Trust Fund to take) any action that,  under the REMIC  Provisions,  if taken or not taken,  as the case may
be, could  (i) endanger the status of each REMIC created  hereunder as a REMIC or (ii) result in the imposition
of a tax upon a REMIC  (including,  but not limited to, the tax on prohibited  transactions  as defined in Code
Section 860F(a)(2)  and the tax on prohibited  contributions set forth in Section 860G(d) of  the Code) (either
such event, an "Adverse REMIC Event") unless the Trustee and the Trust  Administrator  have received an Opinion
of Counsel  (at the  expense  of the party  seeking to take such  action) to the effect  that the  contemplated
action will not endanger such status or result in the imposition of such a tax.

               The Trustee and the Trust  Administrator  shall not take or fail to take any action  (whether or
not  authorized  hereunder)  as to which the Master  Servicer,  a Servicer or the  Depositor  has advised it in
writing that it has  received an Opinion of Counsel to the effect that an Adverse  REMIC Event could occur with
respect to such action.  In addition,  prior to taking any action with respect to a REMIC or their  assets,  or
causing any REMIC created  hereunder to take any action,  which is not expressly  permitted  under the terms of
this Agreement,  the Trustee and the Trust  Administrator will consult with the Master Servicer,  the Servicers
and the Depositor or their  designees,  in writing,  with respect to whether such action could cause an Adverse
REMIC Event to occur with respect to any REMIC created  hereunder  and the Trustee and the Trust  Administrator
shall not take any such  action or cause  that REMIC to take any such  action as to which the Master  Servicer,
any Servicer or the Depositor has advised it in writing that an Adverse REMIC Event could occur.

               In  addition,  prior to taking any action with  respect to any REMIC  created  hereunder  or the
assets therein,  or causing any REMIC created  hereunder to take any action,  which is not expressly  permitted
under the terms of this  Agreement,  the  Holder  of the  Residual  Certificates  will  consult  with the Trust
Administrator  or its  designee,  in writing,  with respect to whether such action could cause an Adverse REMIC
Event to occur with respect to any REMIC created  hereunder,  and no such Person shall take any action or cause
the Trust Fund to take any such action as to which the Trust  Administrator  has advised it in writing  that an
Adverse  REMIC Event could  occur.  The Trustee and the Trust  Administrator  may consult  with counsel to make
such written  advice,  and the cost of same shall be borne by the party seeking to take action not permitted by
this Agreement.

               At all times as may be required by the Code, the Trust  Administrator will, to the extent within
its control and the scope of its duties more specifically set forth herein,  maintain  substantially all of the
assets of each REMIC created hereunder as "qualified  mortgages" as defined in  Section 860G(a)(3)  of the Code
and "permitted investments" as defined in Section 860G(a)(5) of the Code.

(g)     In the event that any tax is imposed on "prohibited  transactions" of any REMIC created  hereunder,  as
defined in  Section 860F(a)(2)  of the Code,  on "net  income from  foreclosure  property"  of such  REMIC,  as
defined in  Section 860G(c) of  the Code,  on any  contributions  to a REMIC  after the  Startup  Day  therefor
pursuant to  Section 860G(d) of  the Code, or any other tax is imposed by the Code or any applicable provisions
of state or local tax laws,  such tax shall be charged  (i) to the related  Servicer,  if such  Servicer has in
its sole  discretion  determined  to indemnify  the Trust Fund against such tax or if such tax arises out of or
results from a breach of such Servicer's duties under  (x) Section 2.07(j)  of this Agreement to not enter into
any  arrangement  by which a REMIC would  receive a fee or other  compensation  for  services or to permit such
REMIC to receive  any  income  from  assets  other  than  "qualified  mortgages"  or  "permitted  investments,"
(y) Section 3.01 of this Agreement to not make or permit any modification,  waiver or amendment of any Mortgage
Loan which would cause any REMIC  created  hereunder to fail to qualify as a REMIC or result in the  imposition
of any tax under  Section 860F(a) or  Section 860G(d) of the Code or (z)  Section 3.11(c) of  this Agreement to
not  cause  any   REO Property   to  fail  to  qualify  as  "foreclosure   property"   within  the  meaning  of
Section 860G(a)(8)  of the Code or to subject any REMIC  created  hereunder to the  imposition  of any federal,
state or local income taxes on the income earned from such  Mortgaged  Property  under  Section 860G(c) of  the
Code of  otherwise,  (ii) to  the Master  Servicer,  if such tax arises out of or results  from a breach by the
Master  Servicer of any of its  obligations  under this  Agreement  or if the Master  Servicer  has in its sole
discretion  determined to indemnify the Trust Fund against such tax, (iii) to the Trust Administrator,  if such
tax arises out of or results  from a breach by the Trust  Administrator  of any of its  obligations  under this
Article II,  (iv) to the  Trustee,  if such tax arises out of or results from a breach by the Trustee of any of
its obligations  under this Article II or  (v) otherwise  against amounts on deposit in the Collection  Account
as provided by Section 3.08  and on the  Distribution  Date(s)  following such  reimbursement  the aggregate of
such taxes shall be allocated in reduction of the Interest  Distribution Amount on each Class entitled  thereto
in the same manner as if such taxes constituted a Prepayment Interest Shortfall.

               In accordance with Section 2.07(c),  the related Servicer,  the Master Servicer,  the Trustee or
the Trust  Administrator,  as  applicable,  shall  promptly  deposit in the  Certificate  Account or Collection
Account, as applicable, any amount of such tax.

               For purposes of this  Section 2.07(g),  a tax is imposed  following  the final and  unappealable
determination  under the Code of the amount of such tax and written  notice  thereof by the Tax Matters  Person
to the party to be charged.

               The  failure  of the  Master  Servicer  or the  related  Servicer  to  promptly  deposit  in the
Certificate  Account  or  Collection  Account,  as  applicable,  any  amount  of such tax  shall be an Event of
Default, as provided in Section 8.01(b).

(h)     The Trust  Administrator  shall,  for federal  income tax  purposes,  maintain  books and records  with
respect to each REMIC  created  hereunder on a calendar  year and on an accrual  basis or as  otherwise  may be
required by the REMIC Provisions.

(i)     Following the Startup Day, none of any Servicer,  the Trustee  (which will act only at the direction of
the Trust  Administrator or as otherwise  specifically  provided in this Agreement) or the Trust  Administrator
shall accept any contributions of assets to any REMIC created  hereunder unless (subject to Section 2.05)  such
Servicer,  the Trustee or the Trust  Administrator shall have received an Opinion of Counsel (at the expense of
the party  seeking to make such  contribution)  to the effect that the inclusion of such assets in a REMIC will
not cause  that  REMIC to fail to  qualify as a REMIC at any time that any  Certificates  are  outstanding,  or
subject that REMIC to any tax under the REMIC Provisions or other applicable  provisions of federal,  state and
local law or ordinances.

(j)     None of any Servicer,  the Trustee (which will act only at the direction of the Trust  Administrator or
as  otherwise  specifically  provided  in  this  Agreement)  or  the  Trust  Administrator  shall  (subject  to
Section 2.05)  enter  into any  arrangement  by which a REMIC  will  receive  a fee or other  compensation  for
services nor permit such REMIC to receive any income from assets other than  "qualified  mortgages"  as defined
in Section 860G(a)(3) of the Code or "permitted investments" as defined in Section 860G(a)(5) of the Code.

(k)     Within 30 days after the Closing  Date,  the Trust  Administrator  shall apply to the Internal  Revenue
Service for an  employer  identification  number for each REMIC  created  hereunder  by means of a Form SS-4 or
other acceptable means and prepare and file with the Internal  Revenue Service Form 8811,  "Information  Return
for Real Estate Mortgage  Investment  Conduits (REMIC) and Issuers of Collateralized Debt Obligations" for each
REMIC created hereunder.

(l)     None of the Trustee  (which will act only at the direction of the Trust  Administrator  or as otherwise
specifically  provided in this Agreement),  the Trust Administrator,  the Master Servicer or any Servicer shall
sell,  dispose of or  substitute  for any of the Mortgage  Loans (except in  connection  with (i) the  default,
imminent  default or foreclosure of a Mortgage Loan,  including but not limited to, the  acquisition or sale of
a  Mortgaged  Property  acquired  by deed in lieu of  foreclosure,  (ii) the  bankruptcy  of any REMIC  created
hereunder,  (iii) the  termination  of any REMIC created  hereunder  pursuant to Article X of this Agreement or
(iv) a  purchase of Mortgage Loans pursuant to Article II or III of this  Agreement) nor acquire any assets for
a REMIC, nor sell or dispose of any investments in the Collection  Account or the Certificate  Account for gain
nor accept any  contributions  to a REMIC  after the  Closing  Date  (a) unless  it has  received an Opinion of
Counsel that such sale,  disposition,  substitution or acquisition  will not affect adversely the status of any
REMIC created  hereunder as a REMIC or (b) unless  the Master  Servicer or such Servicer has  determined in its
sole discretion to indemnify the Trust Fund against such tax.

(m)     In order to enable the Trust  Administrator  to perform its duties as set forth  herein,  the Depositor
shall  provide,  or cause to be provided to the Trust  Administrator,  within ten days after the Closing  Date,
all  information or data the Trust  Administrator  determines to be relevant for tax purposes to the valuations
and  offering  prices  of the  Certificates,  including,  without  limitation,  the  price,  yield,  prepayment
assumption and projected  cash flows of the  Certificates  and the Mortgage  Loans and the Trust  Administrator
shall be  entitled  to rely upon any and all such  information  and data in the  performance  of its duties set
forth  herein.  Thereafter,  the Master  Servicer  shall  provide,  promptly  upon request  therefor,  any such
additional  information or data that the Trustee or the Trust  Administrator  may from time to time  reasonably
request  in order to enable the  Trustee  and the Trust  Administrator  to  perform  their  duties as set forth
herein  and  the  Trustee  and the  Trust  Administrator  shall  be  entitled  to rely  upon  any and all  such
information  and data in the  performance  of its duties set forth  herein.  DLJMC  shall  indemnify  the Trust
Administrator  and  hold  it  harmless  for  any  loss,  liability,  damage,  claim  or  expense  of the  Trust
Administrator  arising  from any failure of the  Depositor  to provide,  or to cause to be  provided,  accurate
information or data to the Trust  Administrator  on a timely basis.  The Master  Servicer  shall  indemnify the
Trustee and the Trust Administrator and hold it harmless for any loss,  liability,  damage, claim or expense of
the Trustee and the Trust  Administrator  arising  from any  failure of the Master  Servicer to provide,  or to
cause to be  provided,  accurate  information  or data  required to be  provided by the Master  Servicer to the
Trustee and the Trust Administrator on a timely basis;  provided,  however,  that if any Servicer shall fail to
provide  such  information  to the Master  Servicer  upon  timely  request for such  information  by the Master
Servicer,  that Servicer shall indemnify the Master Servicer,  the Trustee and the Trust Administrator and hold
it harmless  for any loss,  liability,  damage,  claim or expense of the Master  Servicer,  the Trustee and the
Trust  Administrator  arising from any failure of that  Servicer to provide,  or to cause to be  provided,  the
information  referred to above on a timely basis. The  indemnification  provisions  hereunder shall survive the
termination  of this  Agreement  and shall  extend  to any  co-trustee  and  co-Trust  Administrator  appointed
pursuant to this Agreement.

(n)     The Trust  Administrator shall account for the rights of the Holders of the Group 5 Senior Certificates
and  Class M  Certificates  to receive  payments in respect of Basis Risk  Shortfalls  as rights in an interest
rate cap contract  written by the Class 5-X  Certificateholders  in favor of the Holders of the Group 5  Senior
Certificates  and Class M  Certificates  and not as an obligation of  REMIC III,  whose  obligation to pay such
Certificates  will be subject to a cap equal to the  applicable Net Funds Cap and shall account for such rights
as property  held  separate  and apart from the regular  interests as required by Treasury  regulation  section
1.860G-2(i).  Any  amounts  paid in  respect  of Basis  Risk  Shortfalls  by  REMIC III  shall be  treated as a
distribution to the Class 5-X Certificates.  In addition, the Class 5-X  Certificateholders  shall be deemed to
have entered into a contractual  arrangement  with the Class AR and Class AR-L  Certificateholders  whereby the
Class AR  and  Class AR-L  Certificateholders  agree  to  pay  to  the  Class 5-X  Certificateholders  on  each
Distribution  Date amounts that would, in the absence of such  contractual  agreement,  be  distributable  with
respect to the  residual  interest  in  REMIC III  pursuant  to  Section 4.01(II)(d)(xiii)  (which  amounts are
expected  to be zero).  Thus each  Group 5  Senior  Certificate  and  Class M  Certificate  shall be treated as
representing  ownership  of not only  REMIC III  regular  interests,  but also  ownership  of an interest in an
interest rate cap contract.  Each Class 5-X  Certificate  shall represent an obligation  under an interest rate
cap  contract.  For  purposes  of  determining  the  issue  price of  REMIC III  regular  interests,  the Trust
Administrator shall assume that the interest rate cap contract has a value of $5,000.

               For any  Distribution  Date on which  there is a payment  under the  Group 5  Interest  Rate Cap
Agreement  based on a notional  balance in excess of the Class Principal  Balance of the Group 5  Certificates,
the amount  representing  such excess  payment shall not be an asset of the Trust and,  instead,  shall be paid
into and  distributed  out of a  separate  trust  created by this  Agreement  for the  benefit  of the  Group 5
Certificates  and shall be  distributed to the Group 5  Certificates  pursuant to  Section 4.01(II).  The Trust
Administrator shall not be responsible for any tax reporting with respect to such separate trust.

SECTION 2.08.  Covenants of the Master Servicer and each Servicer.

               The Master  Servicer  and each  Servicer,  severally  and not jointly,  hereby  covenants to the
Depositor, the Trustee and the Trust Administrator as follows:

(a)     Such Servicer or the Master  Servicer  shall comply in the  performance of its  obligations  under this
Agreement with all reasonable  rules and  requirements  of the insurer under each Mortgage  Guaranty  Insurance
Policy; and

(b)     No written  information,  certificate of an officer,  statement  furnished in writing or written report
delivered  to the  Depositor,  any  affiliate  of the  Depositor,  the Trustee or the Trust  Administrator  and
prepared by the Master Servicer or such Servicer  pursuant to this Agreement will contain any untrue  statement
of a material fact.

                                                 ARTICLE III

                                         ADMINISTRATION AND SERVICING
                                               OF MORTGAGE LOANS

SECTION 3.01.  Servicers to Service Mortgage Loans.

               For and on behalf of the  Certificateholders,  as independent contractors of the Trust, (i) each
Servicer,  severally and not jointly,  shall service and administer the related  Non-Designated  Mortgage Loans
in  accordance  with the  terms of this  Agreement  and with  Accepted  Servicing  Practices,  (ii) the  Master
Servicer  shall,  in  accordance  with  Section 3.03  of this  Agreement,  master  service and  administer  the
Non-Designated  Mortgage Loans by overseeing and enforcing the servicing of the  Non-Designated  Mortgage Loans
by the related  Servicer  according to the terms of this  Agreement and (iii) the  Master  Servicer  shall,  in
accordance  with the  Section 3.22  of this  Agreement,  master service and administer the Designated  Mortgage
Loans by overseeing  and enforcing the servicing of the  Designated  Mortgage  Loans by the related  Designated
Servicer  according to the terms of the related  Designated  Servicing  Agreement.  The  obligations of each of
SPS,  Wells Fargo,  JPMorgan and Ocwen  hereunder to service and administer the Mortgage Loans shall be limited
to the SPS Serviced  Mortgage Loans, the Wells Fargo Serviced  Mortgage Loans, the JPMorgan  Serviced  Mortgage
Loans and the Ocwen Serviced  Mortgage Loans,  respectively,  and with respect to the duties and obligations of
each Servicer,  references  herein to related  "Mortgage  Loans" shall be limited to the SPS Serviced  Mortgage
Loans (and the  related  proceeds  thereof  and related  REO  Properties)  in the case of SPS,  the Wells Fargo
Serviced  Mortgage  Loans (and the related  proceeds  thereof and related REO  Properties) in the case of Wells
Fargo,  the JPMorgan  Serviced  Mortgage Loans (and the related proceeds thereof and related REO Properties) in
the case of JPMorgan,  and the Ocwen Serviced  Mortgage Loans (and the related proceeds thereof and related REO
Properties)  in the case of Ocwen,  and in no event shall any  Servicer  have any  responsibility  or liability
with respect to any of the other  Mortgage  Loans.  The  obligations  of the Master  Servicer to master service
and administer the  Non-Designated  Mortgage Loans shall be limited to the Wells Fargo Serviced Mortgage Loans,
the SPS Serviced  Mortgage Loans, the JPMorgan  Serviced  Mortgage Loans, the Ocwen Serviced Mortgage Loans and
the  Special  Serviced   Mortgage  Loans.  In  connection  with  such  servicing  and   administration  of  the
Non-Designated  Mortgage  Loans,  the Master  Servicer and each Servicer  shall have full power and  authority,
acting alone and/or through  Subservicers  as provided in  Section 3.02  hereof,  to do or cause to be done any
and all things that it may deem necessary or desirable in connection  with such  servicing and  administration,
including  but not  limited  to,  the power and  authority,  subject to the terms  hereof  (i) to  execute  and
deliver,  on  behalf  of the  Certificateholders  and the  Trust,  customary  consents  or  waivers  and  other
instruments  and  documents,  (ii) to  consent to transfers of any Mortgaged  Property and  assumptions  of the
Mortgage Notes and related  Mortgages (but only in the manner  provided in this  Agreement),  (iii) to  collect
any Insurance Proceeds and other Liquidation Proceeds,  and (iv) to effectuate  foreclosure or other conversion
of the  ownership of the  Mortgaged  Property  securing any Mortgage  Loan;  provided,  that neither the Master
Servicer nor a Servicer  shall take any action that is  inconsistent  with or  prejudices  the interests of the
Trust Fund or the  Certificateholders  in any Mortgage Loan or the rights and interests of the  Depositor,  the
Trustee,  the Trust  Administrator  or the  Certificateholders  under this  Agreement.  The Master Servicer and
each  Servicer  shall  represent  and protect the interests of the Trust Fund in the same manner as it protects
its own  interests in mortgage  loans in its own portfolio in any claim,  proceeding or litigation  regarding a
Mortgage  Loan,  and shall not make or permit any  modification,  waiver or amendment of any Mortgage Loan that
would cause any REMIC  created  hereunder to fail to qualify as a REMIC or result in the  imposition of any tax
under  Section 860F(a) or  Section 860G(d) of  the Code. Without limiting the generality of the foregoing,  the
Master  Servicer and each  Servicer,  in its own name or in the name of the Depositor and the Trust,  is hereby
authorized and empowered by the Depositor,  the Trust and the Trust Administrator,  when the Master Servicer or
such Servicer  believes it  appropriate in its reasonable  judgment,  to execute and deliver,  on behalf of the
Trust, the Trustee,  the Trust Administrator,  the Depositor,  the  Certificateholders  or any of them, any and
all  instruments  of  satisfaction  or  cancellation,  or of partial or full release or discharge and all other
comparable  instruments,  with respect to the Mortgage Loans, and with respect to the Mortgaged Properties held
for the benefit of the  Certificateholders.  The Master  Servicer and each  Servicer  shall prepare and deliver
to the Depositor  and/or the Trustee  and/or the Trust  Administrator  such documents  requiring  execution and
delivery  by either or both of them as are  necessary  or  appropriate  to enable the Master  Servicer  or such
Servicer to master service and administer or service and administer the Mortgage Loans,  as applicable,  to the
extent  that the Master  Servicer or such  Servicer is not  permitted  to execute  and deliver  such  documents
pursuant to the preceding  sentence.  Upon receipt of such documents,  the Depositor  and/or the Trustee or the
Trust Administrator shall execute such documents and deliver them to the Master Servicer or such Servicer.

               In  accordance  with the  standards  of the first  paragraph  of this  Section 3.01  and  unless
determined in good faith to be a  Nonrecoverable  Advance,  each Servicer shall advance or cause to be advanced
funds as  necessary  for the  purpose of  effecting  the  payment  of taxes and  assessments  on the  Mortgaged
Properties  related to the  Non-Designated  Mortgage Loans,  which advances  constitute  Servicing Advances and
shall be  reimbursable  in the  first  instance  from  related  collections  from the  Mortgagors  pursuant  to
Section 3.06,  and further as provided in  Section 3.08.  In no event will any Servicer be required to make any
Servicing Advance which would constitute a Nonrecoverable  Advance.  The costs incurred by a Servicer,  if any,
in  effecting  the  timely  payments  of taxes and  assessments  on the  Mortgaged  Properties  related  to the
Non-Designated  Mortgage Loans and related insurance premiums shall not, for the purpose of calculating monthly
distributions  to  the  Certificateholders,   be  added  to  the  Stated  Principal  Balances  of  the  related
Non-Designated  Mortgage  Loans,  notwithstanding  that the  terms  of such  Non-Designated  Mortgage  Loans so
permit.  The parties to this Agreement  acknowledge that Servicing  Advances shall be reimbursable  pursuant to
the terms of this  Agreement  and agree that no Servicing  Advance shall be rejected or disallowed by any party
unless it has been shown that such Servicing Advance was not made in accordance with this Agreement.

               Each Servicer  hereby  acknowledges  that, to the extent such Servicer has  previously  serviced
some or all of the  Non-Designated  Mortgage  Loans  pursuant to another  servicing  agreement,  the  servicing
provisions  contained in this  Agreement  shall  supersede  the  servicing  provisions  contained in such other
servicing  agreement from and after the Closing Date, except that such other servicing  agreement shall survive
and govern with respect to excess  servicing  fees and  termination  without  cause.  In  addition,  the Master
Servicer  hereby  acknowledges  that,  to the  extent  the  Master  Servicer  or any  Designated  Servicer  has
previously serviced some or all of the Designated Mortgage Loans pursuant to another servicing  agreement,  the
provisions  contained in the related Designated  Servicing  Agreement shall supersede the provisions  contained
in such other servicing agreement from and after the Closing Date.

               Notwithstanding  anything in this  Agreement  to the  contrary,  the purchase of any Wells Fargo
Serviced  Mortgage Loan by any Person shall be subject to the rights of Wells Fargo to continue  servicing such
Wells Fargo Serviced  Mortgage Loan for the same Servicing Fee  substantially  in accordance  with the terms of
this Agreement.

               With respect to each Mortgage Loan, the related Servicer will fully furnish,  in accordance with
the  Fair  Credit  Reporting  Act  and  its  implementing   regulations,   accurate  and  complete  information
(e.g., favorable  and  unfavorable)  on its borrower  credit files to Equifax,  Experian and Trans Union Credit
Information Company, on a monthly basis.

               Each Servicer is authorized  and empowered by the Trustee,  on behalf of the  Certificateholders
and the Trustee,  in its own name or in the name of any  Subservicer,  when a Servicer or any  Subservicer,  as
the case may be,  believes it  appropriate  in its best  judgment to register any related  Mortgage Loan on the
MERS®  System,  or cause the removal  from the  registration  of such  Mortgage  Loan on the MERS®  System,  to
execute  and  deliver,  on  behalf  of the  Trustee  and the  Certificateholders  or any of  them,  any and all
instruments of assignment and other  comparable  instruments with respect to such assignment or re-recording of
a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns.

SECTION 3.02.  Subservicing; Enforcement of the Obligations of Subservicers.

(a)     The  Non-Designated  Mortgage  Loans may be  subserviced  by a  Subservicer  on  behalf of the  related
Servicer in accordance with the servicing  provisions of this Agreement;  provided,  that the Subservicer  must
be a  FNMA-approved  lender or a FHLMC  seller/servicer  in good standing.  With respect to the  Non-Designated
Mortgage  Loans,  each  Servicer may perform any of its servicing  responsibilities  hereunder or may cause the
Subservicer to perform any such servicing  responsibilities  on its behalf, but the use by such Servicer of the
Subservicer  shall not release such Servicer  from any of its  obligations  hereunder  and such Servicer  shall
remain  responsible  hereunder  for all acts and  omissions  of the  Subservicer  as fully as if such  acts and
omissions were those of such Servicer.  With respect to the Non-Designated  Mortgage Loans, each Servicer shall
pay all fees and expenses of any Subservicer engaged by such Servicer from its own funds.

               Notwithstanding the foregoing,  with respect to the Non-Designated Mortgage Loans, each Servicer
shall be entitled to outsource one or more separate  servicing  functions to a Person (each,  an  "Outsourcer")
that  does not meet the  eligibility  requirements  for a  Subservicer,  so long as such  outsourcing  does not
constitute the delegation of such Servicer's  obligation to perform all or  substantially  all of the servicing
of the related  Non-Designated  Mortgage Loans to such Outsourcer.  In such event, the use by a Servicer of any
such  Outsourcer  shall not  release  the  related  Servicer  from any of its  obligations  hereunder  and such
Servicer shall remain  responsible  hereunder for all acts and omissions of such Outsourcer as fully as if such
acts and  omissions  were those of such  Servicer,  and such  Servicer  shall pay all fees and  expenses of the
Outsourcer from such Servicer's own funds.

               Each Servicer may in connection with its duties as Servicer  hereunder  enter into  transactions
with any of its Affiliates  relating to the  Non-Designated  Mortgage  Loans;  provided that (a) such  Servicer
acts (i) in  accordance  with Accepted  Servicing  Practices and the terms of this  Agreement,  and (ii) in the
ordinary  course of business of such Servicer;  and (b) the terms of such  transaction are no less favorable to
such  Servicer  than it would  obtain in a  comparable  arm's-length  transaction  with a Person that is not an
Affiliate of such Servicer.  Notwithstanding  the preceding  sentence,  any such transaction between a Servicer
and any of its  Affiliates  shall not release such  Servicer  from any of its  obligations  hereunder  and such
Servicer shall remain  responsible  hereunder for all acts and omissions of such Affiliate with respect to such
Mortgage  Loans  serviced by it as fully as if such acts and omissions  were those of such  Servicer.  Any fees
and expenses  relating to such  transaction  between such  Servicer and its  Affiliate  that are not  otherwise
reimbursable  to such Servicer  pursuant to this Agreement  shall be borne by the parties thereto and shall not
be an expense or fee of the Trust,  the  Depositor,  the Trustee,  the Trust  Administrator,  the Seller or the
Master Servicer.

(b)     With respect to any Non-Designated  Mortgage Loans, at the cost and expense of a Servicer,  without any
right of reimbursement from the Depositor,  the Trustee,  the Trust Administrator or the applicable  Collection
Account,  such Servicer shall be entitled to terminate the rights and  responsibilities  of its Subservicer and
arrange  for  any  servicing   responsibilities  to  be  performed  by  a  successor  Subservicer  meeting  the
requirements set forth in  Section 3.02(a),  provided,  however,  that nothing contained herein shall be deemed
to prevent or  prohibit  such  Servicer,  at such  Servicer's  option,  from  electing  to service  the related
Non-Designated  Mortgage Loans itself.  In the event that a Servicer's  responsibilities  and duties under this
Agreement  are  terminated  pursuant  to  Section 8.01,  and if  requested  to do so by the  Trustee  or  Trust
Administrator  or such Servicer  shall, at its own cost and expense  terminate the rights and  responsibilities
of its  Subservicer  as  soon as is  reasonably  possible.  Each  Servicer  shall  pay all  fees,  expenses  or
penalties  necessary  in order to  terminate  the  rights and  responsibilities  of its  Subservicer  from such
Servicer's own funds without any right of reimbursement from the Depositor,  Trustee,  Trust Administrator,  or
the applicable Collection Account.

(c)     Notwithstanding any of the provisions of this Agreement relating to agreements or arrangements  between
a Servicer and its  Subservicer  or a Servicer and its  Outsourcer,  or any  reference  herein to actions taken
through the  Subservicer,  the  Outsourcer,  or otherwise,  the related  Servicer  shall not be relieved of its
obligations to the Depositor,  the Trust, Trustee, the Trust Administrator or  Certificateholders  and shall be
obligated  to the same  extent  and under the same  terms and  conditions  as if it alone  were  servicing  and
administering  the related  Non-Designated  Mortgage  Loans.  Each Servicer  shall be entitled to enter into an
agreement  with its  Subservicer  and Outsourcer for  indemnification  of such Servicer by such  Subservicer or
Outsourcer,  as applicable,  and nothing  contained in this  Agreement  shall be deemed to limit or modify such
indemnification.

               For purposes of this  Agreement,  a Servicer  shall be deemed to have received any  collections,
recoveries  or  payments  with  respect to the related  Non-Designated  Mortgage  Loans that are  received by a
related Subservicer regardless of whether such payments are remitted by the Subservicer to such Servicer.

               Any   Subservicing   Agreement  and  any  other   transactions  or  services   relating  to  the
Non-Designated  Mortgage Loans involving a Subservicer  shall be deemed to be between the Subservicer,  and the
related Servicer alone,  and the Depositor,  the Trustee,  the Trust  Administrator,  the Master Servicer,  the
other  Servicers and the Special  Servicer shall have no obligations,  duties or liabilities  with respect to a
Subservicer  including no obligation,  duty or liability of the Depositor,  Trustee,  the Trust  Administrator,
the Master Servicer, the Special Servicer or other Servicers to pay a Subservicer's fees and expenses.

(d)     Each Servicer is hereby authorized to enter into a financing or other facility  (any such  arrangement,
a  "Facility")  under  which  (i) such  Servicer  assigns or pledges to another  person  (a "Lender")  (A) such
Servicer's  rights under this  Agreement to be reimbursed for any Advances or Servicing  Advances,  and (B) any
and all  rights of such  Servicer  under this  Agreement  resulting  from such  Servicer's  performance  of its
obligations  under this  Agreement,  including,  without  limitation,  any  Servicing  Fees,  interest  income,
Ancillary  Income,  and other  payments  received by such  Servicer for  servicing  the Mortgage  Loans related
thereto and (ii) the Lender agrees to fund some or all Advances and/or Servicing  Advances  required to be made
by  such  Servicer  pursuant  to this  Agreement.  No  consent  of the  Trustee,  Trust  Administrator,  Master
Servicer,  Certificateholders,  Rating  Agency or any other party is required  before such  Servicer  may enter
into a Facility;  provided,  however, that the consent of the Trust Administrator shall be required before such
Servicer may cause to be  outstanding  at one time more than one  Facility.  Notwithstanding  the  existence of
any Facility,  such Servicer shall remain  obligated  pursuant to this Agreement to make Advances and Servicing
Advances  pursuant to and as  required by this  Agreement,  and to perform all duties and  obligations  of such
Servicer under this Agreement and shall not be relieved of such obligations by virtue of such Facility.

SECTION 3.03.  Master Servicing by Master Servicer.

               For and on behalf of the  Certificateholders,  the Master Servicer shall oversee and enforce the
obligation  of Wells  Fargo,  SPS,  JPMorgan  and Ocwen to service  and  administer  the Wells  Fargo  Serviced
Mortgage Loans,  SPS Serviced  Mortgage Loans,  JPMorgan  Serviced  Mortgage Loans and Ocwen Serviced  Mortgage
Loans,  respectively,  in accordance  with the terms of this  Agreement and shall have full power and authority
to do any and all things which it may deem  necessary or desirable  in  connection  with such master  servicing
and  administration.  In  performing  its  obligations  hereunder,  the Master  Servicer  shall act in a manner
consistent  with this  Agreement and with  customary and usual  standards of practice of prudent  mortgage loan
master  servicers.  Furthermore,  the Master Servicer shall oversee and consult with the Servicers as necessary
from  time-to-time  to carry out the  Master  Servicer's  obligations  hereunder,  shall  receive,  review  and
evaluate all reports,  information  and other data  provided to the Master  Servicer by the Servicers and shall
cause each  Servicer to perform and observe the  covenants,  obligations  and  conditions  to be  performed  or
observed by such Servicer under this Agreement.

               With respect to any  Distribution  Date,  no later than the related Cash  Remittance  Date,  the
Master Servicer shall remit to the Trust  Administrator  for deposit in the  Certificate  Account the amount of
the Compensating  Interest Payment for the Master Servicer,  with respect to the Wells Fargo Serviced  Mortgage
Loans, SPS Serviced  Mortgage Loans,  Ocwen Serviced  Mortgage Loans and JPMorgan  Serviced  Mortgage Loans and
the  Designated  Mortgage  Loans,  for the related  Prepayment  Period to the extent Wells Fargo,  SPS,  Ocwen,
JPMorgan or the related  Designated  Servicer  default in their obligation to make such  Compensating  Interest
Payment  pursuant to  Section 3.05.  The  aggregate of such deposits  shall be made from the Master  Servicer's
own funds, without reimbursement therefor.

SECTION 3.04.  Trustee to Act as Master Servicer or Servicer.

               In the event that (A) the  Master  Servicer  shall for any  reason no longer be Master  Servicer
hereunder or (B) any Servicer  shall for any reason no longer be a Servicer  hereunder and, with respect to any
Servicer,  the Master Servicer shall for any reason no longer be Master Servicer hereunder (including,  in each
case,  by reason of an Event of  Default),  the  Trustee or its  successor  shall  thereupon  assume all of the
rights and obligations of the Master Servicer or such Servicer  hereunder arising  thereafter  (except that the
Trustee shall not be (i) liable  for losses of the Master  Servicer or such Servicer  pursuant to  Section 3.09
hereof or any acts or omissions of the related  predecessor of the Master Servicer or such Servicer  hereunder,
(ii) obligated  to make  Advances if it is  prohibited  from doing so by  applicable  law,  (iii) obligated  to
effectuate  repurchases  or  substitutions  of  Mortgage  Loans  hereunder  including,   but  not  limited  to,
repurchases or  substitutions  of Mortgage Loans pursuant to Section 2.02 or 2.03 hereof or (iv) deemed to have
made  any  representations  and  warranties  of the  Master  Servicer  or such  Servicer  hereunder).  Any such
assumption shall be subject to Section 8.02  hereof.  Notwithstanding the foregoing,  if the Trustee has become
the successor to the Master Servicer or a Servicer  hereunder,  the Trustee may, if it shall be unwilling to so
act, or shall, if it is unable to so act,  appoint,  or petition a court of competent  jurisdiction to appoint,
any established  mortgage loan servicing  institution,  the appointment of which does not adversely  affect the
then-current  rating of the  Certificates,  as the successor to the Master Servicer or a Servicer  hereunder in
the assumption of all or any part of the  responsibilities,  duties or  liabilities  of the Master  Servicer or
such  Servicer,  as  applicable,  provided  that such  successor to the Master  Servicer or such  Servicer,  as
applicable,  shall not be deemed to have made any  representation  or warranty as to any Mortgage  Loan made by
the Master Servicer or such Servicer, as applicable.

Servicer,  deliver to the assuming party all documents and records relating to each  Subservicing  Agreement or

SECTION 3.05.  Collection of Mortgage Loans; Collection Accounts; Certificate Account.

(a)     Continuously  from the date hereof  until the  principal  and interest on all  Non-Designated  Mortgage
Loans have been paid in full or such  Non-Designated  Mortgage  Loans have become  Liquidated  Mortgage  Loans,
each Servicer shall proceed in accordance with Accepted  Servicing  Practices to collect all payments due under
each of the  related  Non-Designated  Mortgage  Loans when the same shall  become due and payable to the extent
consistent with this Agreement and the terms and provisions of any related Mortgage  Guaranty  Insurance Policy
and shall take special care with respect to the  Non-Designated  Mortgage  Loans for which a Servicer  collects
escrow payments in ascertaining  and estimating  Escrow Payments and all other charges that will become due and
payable with respect to the  Non-Designated  Mortgage Loans and the related  Mortgaged  Properties,  to the end
that the  installments  payable by the related  Mortgagors  will be  sufficient to pay such charges as and when
they become due and payable.  Consistent with the foregoing,  in connection with Non-Designated  Mortgage Loans
which it is directly  servicing,  each Servicer may in its discretion  (i) waive any late payment charge or any
prepayment  charge or penalty interest in connection with the prepayment of a Non-Designated  Mortgage Loan and
(ii) extend  the Due  Dates  for  payments  due on a  Mortgage  Note for a period  not  greater  than 180 days;
provided,  however, that no such Servicer can extend the maturity of any such Non-Designated Mortgage Loan past
the date on which the final  payment is due on the latest  maturing  Mortgage  Loan as of the Cut-off  Date. In
the event of any such  arrangement,  the related  Servicer  shall make  Advances on the related  Non-Designated
Mortgage Loans in accordance  with the  provisions of  Section 5.01  during the scheduled  period in accordance
with  the  amortization  schedule  of such  Mortgage  Loan  without  modification  thereof  by  reason  of such
arrangements.  No Servicer  shall be required to institute or join in litigation  with respect to collection of
any payment  (whether  under a  Mortgage,  Mortgage  Note or  otherwise  or against any public or  governmental
authority with respect to a taking or condemnation)  if it reasonably  believes that enforcing the provision of
the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law.

(b)     Each Servicer shall  segregate and hold all funds collected and received  pursuant to a  Non-Designated
Mortgage  Loan  separate  and apart  from any of its own funds  and  general  assets  and shall  establish  and
maintain one or more Collection Accounts,  in the form of time deposit or demand accounts,  titled "[Servicer's
name],  in trust for the Holders of Adjustable  Rate Mortgage Trust 2005-11,  Adjustable  Rate  Mortgage-Backed
Pass-Through  Certificates,  Series  2005-11" or, if established and maintained by a Subservicer on behalf of a
Servicer,  "[Subservicer's  name], in trust for [Servicer's name]" or "[Subservicer's  name], as agent, trustee
and/or bailee of principal and interest  custodial  account for [Servicer's  name], its successors and assigns,
for various  owners of interest in [Servicer's  name]  mortgage-backed  pools.  In the event that a Subservicer
employs a subservicer,  the Collection Account shall be titled "[name of Subservicer's  subservicer],  in trust
for  [Subservicer's  name]." Each  Collection  Account  maintained by each  Servicer  (other than Wells Fargo),
shall be an  Eligible  Account  acceptable  to the  Depositor  and the  Trust  Administrator.  Each  Collection
Account  maintained by Wells Fargo shall be an Eligible  Account.  Funds deposited in a Collection  Account may
be drawn on by the related  Servicer in  accordance  with  Section 3.08.  Any funds  deposited  in a Collection
Account  shall either be invested in Eligible  Investments  or at all times be fully insured to the full extent
permitted under applicable law.

(c)     Each Servicer  shall  deposit in the  applicable  Collection  Account on a daily basis (with respect to
Ocwen and SPS,  within two Business Days of receipt),  unless  otherwise  indicated,  and retain  therein,  the
following  collections  remitted by  Subservicers  or payments  received by such  Servicer and payments made by
such Servicer  subsequent  to the Cut-off Date,  other than payments of principal and interest due on or before
the Cut-off Date:

(i)     all  payments on account of principal  on the related  Non-Designated  Mortgage  Loans,  including  all
        Principal Prepayments;

(ii)    all payments on account of interest on the related  Non-Designated  Mortgage  Loans adjusted to the per
        annum  rate  equal to the  Mortgage  Rate  reduced  by the sum of the  related  Expense  Fee  Rate,  as
        applicable;

(iii)   all Liquidation Proceeds on the related Non-Designated Mortgage Loans;

(iv)    all Insurance  Proceeds on the related  Non-Designated  Mortgage Loans including amounts required to be
        deposited  pursuant to  Section 3.09  (other than proceeds to be held in the Escrow Account and applied
        to the restoration or repair of the Mortgaged  Property or released to the Mortgagor in accordance with
        Section 3.09);

(v)     all Advances made by such Servicer pursuant to Section 5.01;

(vi)    no later than the withdrawal from the Collection Account pursuant to Section 3.08(a)(viii) each  month,
        the  applicable  amount  of the  Compensating  Interest  Payment  for  such  Servicer  for the  related
        Prepayment  Period.  The  aggregate  of such  deposits  shall be made from such  Servicer's  own funds,
        without reimbursement therefor;

(vii)   any  amounts  required  to be  deposited  by such  Servicer  in  respect  of net  monthly  income  from
        REO Property related to any Non-Designated Mortgage Loan pursuant to Section 3.11;

(viii)  all Assigned Prepayment Premiums, if applicable; and

(ix)    any other amounts required to be deposited hereunder.

               The foregoing  requirements  for deposit into each  Collection  Account  shall be exclusive,  it
being  understood  and agreed that,  without  limiting the  generality  of the  foregoing,  with respect to the
Non-Designated  Mortgage  Loans,  Ancillary  Income need not be deposited by such Servicer into such Collection
Account.  In addition,  notwithstanding  the  provisions  of this  Section 3.05,  each Servicer may deduct from
amounts received by it, prior to deposit into the applicable  Collection Account,  any portion of any Scheduled
Payment  representing  (i) the applicable Servicing Fee and any other amounts owed to such Servicer pursuant to
Section 3.14 and  (ii) with  respect to each  Non-Designated  Mortgage  Loan covered by a Lender Paid  Mortgage
Guaranty  Insurance  Policy,  any amounts  required to effect  timely  payment of the premiums on such Mortgage
Guaranty  Insurance  Policy  pursuant to  Section 3.09(c).  In the event that a Servicer shall remit any amount
not required to be remitted,  it may at any time  withdraw or direct the  institution  maintaining  the related
Collection Account to withdraw such amount from such Collection  Account,  any provision herein to the contrary
notwithstanding.  Such  withdrawal or direction may be  accomplished  by delivering  written  notice thereof to
the  Trustee or such other  institution  maintaining  such  Collection  Account  which  describes  the  amounts
deposited in error in such Collection  Account.  Each Servicer shall maintain  adequate records with respect to
all  withdrawals  made by it pursuant to this  Section.  All funds  deposited in a Collection  Account shall be
held in trust for the Certificateholders until withdrawn in accordance with Section 3.08(a).

(d)     On or prior to the Closing Date, the Trust  Administrator  shall  establish and maintain,  on behalf of
the  Certificateholders,  the  Certificate  Account.  The Trust  Administrator  shall,  promptly  upon receipt,
deposit in the Certificate Account and retain therein the following:

(i)     the  aggregate  amount  remitted  by each  Servicer  of  Non-Designated  Mortgage  Loans  to the  Trust
        Administrator  pursuant to  Section 3.08(a)(viii) and  (x) and the  aggregate  amount  remitted by each
        Designated  Servicer  to the  Master  Servicer  or Trust  Administrator  pursuant  to their  respective
        Designated Servicing Agreements, in each case including any Assigned Prepayment Premiums;

(ii)    any amount  deposited by the Trust  Administrator  pursuant to  Section 3.05(e) in  connection with any

        Section 3.22(b); and

               In the event that the Master Servicer or a Servicer shall remit to the Trust  Administrator  any
amount not  required to be remitted,  the Master  Servicer or such  Servicer,  as  applicable,  may at any time
direct the Trust  Administrator to withdraw such amount from the Certificate  Account,  any provision herein to
the contrary  notwithstanding.  Such direction may be  accomplished  by delivering an Officer's  Certificate to
the Trust  Administrator which describes the amounts deposited in error in the Certificate  Account.  All funds
deposited  in  the  Certificate   Account  shall  be  held  by  the  Trust   Administrator  in  trust  for  the
Certificateholders  until  disbursed  in  accordance  with this  Agreement  or  withdrawn  in  accordance  with
Section 3.08(b).  In no  event  shall  the  Trust  Administrator  incur  liability  for  withdrawals  from  the
Certificate Account at the direction of the Master Servicer or any Servicer.

(e)     Each  institution at which a Collection  Account or the Certificate  Account is maintained shall either
hold such funds on deposit  uninvested  or shall invest the funds therein as directed in writing by the related
Servicer, the Trust Administrator or the Depositor,  respectively, in Eligible Investments,  which shall mature
not later than (i) in the case of a Collection  Account,  the Cash  Remittance Date and (ii) in the case of the
Certificate  Account,  the Business Day immediately  preceding the  Distribution  Date, or on the  Distribution
Date, with respect to Eligible Investments  invested with an affiliate of the Trust  Administrator.  All income
and gain net of any losses  realized  from any such  balances or investment of funds on deposit in a Collection
Account  shall be for the benefit of the related  Servicer as servicing  compensation  and shall be remitted to
it monthly as provided  herein.  The amount of any  realized  losses in a  Collection  Account  incurred in any
such account in respect of any such  investments  shall promptly be deposited by the related Servicer (from its
own funds) in the  related  Collection  Account.  Neither  the  Trustee  nor the Trust  Administrator  shall be
liable for the amount of any loss  incurred in respect of any  investment  or lack of  investment of funds held
in a Collection  Account and made in accordance with this  Section 3.05.  All income and gain net of any losses
realized from any such  investment of funds on deposit in the  Certificate  Account shall be for the benefit of
the Trust  Administrator  as compensation  and shall be remitted to it monthly as provided  herein.  The amount

(a)     Each  Servicer  shall cause to be  maintained  for each  related  Non-Designated  Mortgage  Loan hazard
insurance such that all buildings  upon the related  Mortgaged  Property are insured by a generally  acceptable
insurer rated  either:  "V" or better in the current  Best's Key Rating Guide  ("Best's") or acceptable to FNMA
or FHLMC  against loss by fire,  hazards of extended  coverage and such other  hazards as are  customary in the
area where the related  Mortgaged  Property is located,  in an amount  which is at least equal to the lesser of
(i) the replacement value of the improvements  securing such Non-Designated  Mortgage Loan and (ii) the greater
of (A) the outstanding  principal balance of such Non-Designated  Mortgage Loan and (B) an amount such that the
proceeds of such policy shall be sufficient to prevent the  Mortgagor  and/or the mortgagee  from becoming a co
insurer.

               If upon  origination of the  Non-Designated  Mortgage Loan, the related  Mortgaged  Property was
located in an area  identified in the Federal  Register by the Federal  Emergency  Management  Agency as having
special flood hazards (and such flood insurance has been made  available),  the related  Servicer shall cause a
flood insurance  policy to be maintained with respect to such  Non-Designated  Mortgage Loan. Such policy shall
meet the requirements of the current  guidelines of the Federal  Insurance  Administration  and be in an amount
representing  coverage equal to the lesser of (i) the minimum amount required,  under the terms of coverage, to
compensate  for any  damage  or loss on a  replacement  cost  basis (or the  unpaid  principal  balance  of the
mortgage if replacement  cost coverage is not available for the type of building  insured) and (ii) the maximum
amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended.

               If a Mortgage  related to a  Non-Designated  Mortgage Loan is secured by a unit in a condominium
project,  the related Servicer shall verify that the coverage  required of the owner's  association,  including
hazard,  flood,  liability,  and fidelity coverage,  is being maintained in accordance with the requirements of
the related Servicer for mortgage loans that it services on its own account.

               Each  Servicer  shall  cause  to  be  maintained  on  each  Mortgaged   Property  related  to  a
Non-Designated  Mortgage Loan such other  additional  special hazard  insurance as may be required  pursuant to
such  applicable  laws and  regulations  as shall at any time be in force and as shall require such  additional
insurance,  or pursuant to the requirements of any Mortgage  Guaranty  Insurance  Policy insurer,  or as may be
required to conform with  Accepted  Servicing  Practices to the extent  permitted  by the  Mortgage  Note,  the
Mortgage or applicable  law provided that the related  Servicer  shall not be required to bear the cost of such
insurance.

               All  policies  required  hereunder  shall name the  related  Servicer as loss payee and shall be
endorsed  with  standard or union  mortgagee  clauses,  without  contribution,  which  shall  provide for prior
written notice of any cancellation, reduction in amount or material change in coverage.

               Each Servicer shall not interfere with the  Mortgagor's  freedom of choice at the origination of
such Non-Designated  Mortgage Loan in selecting either his insurance carrier or agent, provided,  however, that
such Servicer shall not accept any such insurance  policies from insurance  companies unless such companies are
rated:  B:III or better in  Best's or  acceptable  to FNMA or FHLMC  and are  licensed  to do  business  in the
jurisdiction  in which the  Mortgaged  Property is located.  The related  Servicer  shall  determine  that such
policies  provide  sufficient  risk coverage and amounts,  that they insure the property  owner,  and that they
properly describe the property address.

               Pursuant to  Section 3.05,  any amounts  collected by a Servicer under any such policies  (other
than amounts to be  deposited in the related  Escrow  Account and applied to the  restoration  or repair of the
related Mortgaged Property,  or property acquired in liquidation of the Non-Designated  Mortgage Loan, or to be
released to the Mortgagor,  in accordance with such Servicer's normal servicing  procedures) shall be deposited
in the related Collection Account (subject to withdrawal pursuant to Section 3.08(a)).

               Any cost incurred by a Servicer in maintaining  any such insurance shall not, for the purpose of
calculating  monthly  distributions to the  Certificateholders  or remittances to the Trust  Administrator  for
their benefit,  be added to the principal balance of the  Non-Designated  Mortgage Loan,  notwithstanding  that
the terms of the  Non-Designated  Mortgage Loan so permit.  Such costs shall constitute a Servicing Advance and
will  be  reimbursable  to  the  related  Servicer  to the  extent  permitted  by  Section 3.08  hereof.  It is
understood  and agreed that no  earthquake  or other  additional  insurance is to be required of any  Mortgagor
related to a Non-Designated  Mortgage Loan or maintained on property  acquired in respect of a Mortgage related
to a  Non-Designated  Mortgage Loan other than pursuant to such applicable laws and regulations as shall at any
time be in force and as shall require such additional insurance.

(b)     In the event that a  Servicer  shall  obtain and  maintain a blanket  policy  insuring  against  losses
arising from fire and hazards  covered under extended  coverage on all of the related  Non-Designated  Mortgage
Loans,  then, to the extent such policy provides  coverage in an amount equal to the amount  required  pursuant
to  Section 3.09(a) and   otherwise  complies  with  all  other  requirements  of  Section 3.09(a),   it  shall
conclusively  be  deemed  to have  satisfied  its  obligations  as set forth in  Section 3.09(a).  Any  amounts
collected by a Servicer  under any such policy  relating to a  Non-Designated  Mortgage Loan shall be deposited
in the related Collection Account subject to withdrawal  pursuant to  Section 3.08(a).  Such policy may contain
a  deductible  clause,  in which case,  in the event that there shall not have been  maintained  on the related
Mortgaged Property a policy complying with  Section 3.09(a),  and there shall have been a loss which would have
been covered by such policy,  the related Servicer shall deposit in the related  Collection Account at the time
of such loss the amount not  otherwise  payable under the blanket  policy  because of such  deductible  clause,
such amount to be deposited from such Servicer's funds,  without  reimbursement  therefor.  Upon request of the
Trust  Administrator,  a Servicer shall cause to be delivered to the Trust  Administrator a certified true copy
of such policy and a statement  from the insurer  thereunder  that such policy shall in no event be  terminated
or materially  modified  without 30 days' prior written notice to the Trust  Administrator.  In connection with
its activities as Servicer of the related  Non-Designated  Mortgage Loans, such Servicer agrees to present,  on
behalf of itself,  the  Depositor,  and the Trust  Administrator  for the  benefit  of the  Certificateholders,
claims under any such blanket policy.

(c)     With respect to each  Non-Designated  Mortgage Loan with a  Loan-to-Value  Ratio in excess of 80% which
the Seller  represented  to be covered by a Mortgage  Guaranty  Insurance  Policy as of the Cut-off  Date,  the
related  Servicer  shall,  without  any cost to the  Depositor  or Trust  Administrator,  maintain or cause the
Mortgagor to maintain in full force and effect a Mortgage  Guaranty  Insurance  Policy insuring that portion of
the  Non-Designated  Mortgage  Loan in excess of 75% of value,  and shall pay or shall cause the  Mortgagor  to
pay, the premium  thereon on a timely basis,  until the  loan-to-value  ratio of such  Non-Designated  Mortgage
Loan is reduced  to 80%,  based on either  (i) a  current  appraisal  of the  Mortgaged  Property  or  (ii) the
appraisal of the Mortgaged  Property obtained at the time the Non-Designated  Mortgage Loan was originated.  In
the event that such Mortgage  Guaranty  Insurance Policy shall be terminated prior to the  loan-to-value  ratio
of such  Non-Designated  Mortgage  Loan being  reduced to 80%, the related  Servicer  shall obtain from another
Qualified Insurer a comparable  replacement  policy,  with a total coverage equal to the remaining  coverage of
such terminated  Mortgage Guaranty Insurance Policy. If the insurer shall cease to be a Qualified Insurer,  the
related  Servicer  shall  determine  whether  recoveries  under the  Mortgage  Guaranty  Insurance  Policy  are
jeopardized  for reasons  related to the financial  condition of such insurer,  it being  understood  that such
Servicer shall in no event have any  responsibility  or liability for any failure to recover under the Mortgage
Guaranty  Insurance  Policy  for such  reason.  If the  related  Servicer  determines  that  recoveries  are so
jeopardized,  it shall  notify  the  Mortgagor,  if  required,  and obtain  from  another  Qualified  Insurer a
replacement  insurance  policy.  The  related  Servicer  shall  not take  any  action  which  would  result  in
noncoverage under any applicable  Mortgage Guaranty  Insurance Policy of any loss which, but for the actions of
such Servicer would have been covered thereunder.  In connection with any assumption or substitution  agreement
entered into or to be entered into pursuant to  Section 3.10,  each Servicer shall promptly  notify the insurer
under the related Mortgage  Guaranty  Insurance Policy, if any, of such assumption or substitution of liability
in accordance with the terms of such Mortgage  Guaranty  Insurance  Policy and shall take all actions which may
be required by such  insurer as a condition  to the  continuation  of  coverage  under such  Mortgage  Guaranty
Insurance  Policy,  provided that such  required  actions are in compliance  with all  applicable  law. If such
Mortgage  Guaranty  Insurance Policy is terminated as a result of such assumption or substitution of liability,
the related  Servicer  shall  obtain a  replacement  Mortgage  Guaranty  Insurance  Policy as  provided  above;
provided  that under  applicable  law and the terms of the related  Mortgage Note and Mortgage the cost of such
policy may be charged to the successor Mortgagor.

               With respect to each  Non-Designated  Mortgage Loan covered by a Lender Paid  Mortgage  Guaranty
Insurance  Policy,  the  applicable  Servicer  shall effect  timely  payment of the  premiums on such  Mortgage
Guaranty  Insurance  Policy from amounts on deposit in the  Collection  Account,  or deducted by such  Servicer
prior to deposit  into the  applicable  Collection  Account  pursuant to  Section 3.05(c) with  respect to such
Non-Designated  Mortgage  Loan. If amounts on deposit in the Collection  Account,  or deducted by such Servicer
prior to deposit  into the  applicable  Collection  Account  pursuant to  Section 3.05(c) with  respect to such
Non-Designated  Mortgage  Loan are not  sufficient  to pay the  premiums on such  Mortgage  Guaranty  Insurance
Policy,  the  applicable  Servicer  shall  effect  timely  payment of such  premiums,  and such costs  shall be
recoverable  by such  Servicer  from the related  Liquidation  Proceeds  or  otherwise  as a Servicing  Advance
pursuant  to  Section 3.08(a).  With  respect  to each  Non-Designated  Mortgage  Loan  covered  by a  Mortgage
Guaranty  Insurance  Policy  that is not a Lender Paid  Mortgage  Guaranty  Insurance  Policy,  the  applicable
Servicer  shall effect timely  payment of the premiums on such Mortgage  Guaranty  Insurance  Policy,  and such
costs not otherwise  recoverable  from the  Mortgagor  shall be  recoverable  by such Servicer from the related
Liquidation Proceeds or otherwise as a Servicing Advance pursuant to Section 3.08(a).

(d)     In connection  with its activities as servicer,  each Servicer shall prepare and present,  on behalf of
itself, the Depositor,  the Trust, the Trustee, the Trust Administrator and the  Certificateholders,  claims to
the insurer  under any Mortgage  Guaranty  Insurance  Policy  related to a  Non-Designated  Mortgage  Loan in a
timely fashion in accordance  with the terms of such Mortgage  Guaranty  Insurance  Policy and, in this regard,
to take such reasonable action as shall be necessary to permit recovery under any Mortgage  Guaranty  Insurance
Policy respecting defaulted  Non-Designated Mortgage Loans. Pursuant to Section 3.05,  any amounts collected by
a Servicer under any Mortgage Guaranty Insurance Policy shall be deposited in the related  Collection  Account,
subject to withdrawal pursuant to Section 3.08.

(e)     With respect to any  Non-Designated  Mortgage  Loan,  each Servicer need not obtain the approval of the
Trustee or the Trust  Administrator  prior to releasing any Insurance  Proceeds to the related  Mortgagor to be
applied to the  restoration or repair of the related  Mortgaged  Property if such release is in accordance with
Accepted  Servicing  Practices.  At a minimum,  each  Servicer  shall comply with the  following  conditions in
connection with any such release of Insurance Proceeds:

(i)     such  Servicer  shall  receive  satisfactory  independent  verification  of  completion  of repairs and
        issuance of any required approvals with respect thereto;

(ii)    such  Servicer  shall take all steps  necessary to preserve  the priority of the lien of the  Mortgage,
        including, but not limited to requiring waivers with respect to mechanics' and materialmen's liens; and

(iii)   pending repairs or restoration,  such Servicer shall place the Insurance Proceeds in the related Escrow
        Account.

(f)     With respect to any Non-Designated  Mortgage Loan, if the Trust Administrator is named as an additional
loss payee,  the related  Servicer is hereby  empowered  to endorse any loss draft  issued in respect of such a
claim in the name of the Trustee or the Trust Administrator.

SECTION 3.10.  Enforcement of Due on Sale Clauses; Assumption Agreements.

(a)     With respect to any  Non-Designated  Mortgage Loan, each Servicer shall use its best efforts to enforce
any  "due-on-sale"  provision  contained in any related Mortgage or Mortgage Note and to deny assumption by the
person to whom the  Mortgaged  Property  has been or is about to be sold whether by absolute  conveyance  or by
contract of sale, and whether or not the Mortgagor  remains liable on the Mortgage and the Mortgage Note.  When
the Mortgaged  Property has been conveyed by the Mortgagor,  the related  Servicer  shall, to the extent it has
knowledge of such conveyance,  exercise its rights to accelerate the maturity of such  Non-Designated  Mortgage
Loan under the  "due-on-sale"  clause  applicable  thereto,  provided,  however,  that such Servicer  shall not
exercise  such rights if  prohibited  by law from doing so or if the  exercise of such rights  would  impair or
threaten to impair any recovery under the related Mortgage Guaranty Insurance Policy, if any.

(b)     With respect to any Non-Designated  Mortgage Loan, if a Servicer reasonably believes it is unable under
applicable  law to enforce such  "due-on-sale"  clause,  such Servicer  shall enter into (i) an  assumption and
modification  agreement with the person to whom such property has been conveyed,  pursuant to which such person
becomes liable under the Mortgage Note and the original  Mortgagor  remains liable thereon or (ii) in the event
such Servicer is unable under  applicable  law to require that the original  Mortgagor  remain liable under the
Mortgage Note, a substitution of liability  agreement with the purchaser of the Mortgaged  Property pursuant to
which the  original  Mortgagor is released  from  liability  and the  purchaser  of the  Mortgaged  Property is
substituted  as  Mortgagor  and becomes  liable under the  Mortgage  Note.  Notwithstanding  the  foregoing,  a
Servicer  shall not be deemed to be in default  under this  Section by  reason of any  transfer  or  assumption
which such Servicer  reasonably  believes it is restricted by law from preventing,  for any reason  whatsoever.
In connection with any such assumption,  no material term of the Mortgage Note,  including without  limitation,
the Mortgage  Rate borne by the related  Mortgage  Note,  the term of the  Non-Designated  Mortgage Loan or the
outstanding principal amount of the Non-Designated Mortgage Loan shall be changed.

(c)     To the extent that any  Non-Designated  Mortgage Loan is assumable,  the related Servicer shall inquire
diligently into the  creditworthiness of the proposed transferee,  and shall use the underwriting  criteria for
approving the credit of the proposed  transferee  which are used by FNMA with respect to underwriting  mortgage
loans of the same type as the  Non-Designated  Mortgage  Loans.  If the credit of the proposed  transferee does
not meet such  underwriting  criteria,  the related Servicer  diligently  shall, to the extent permitted by the
Mortgage or the Mortgage Note and by applicable  law,  accelerate the maturity of the  Non-Designated  Mortgage
Loan.

(d)     With  respect to any  Non-Designated  Mortgage  Loan,  subject to each  Servicer's  duty to enforce any
due-on-sale  clause to the extent set forth in this  Section 3.10,  in any case in which the related  Mortgaged
Property  has  been  conveyed  to a Person  by the  related  Mortgagor,  and such  Person  is to enter  into an
assumption  agreement or  modification  agreement or  supplement to the Mortgage Note or Mortgage that requires
the signature of the Trustee,  or if an instrument of release  signed by the Trustee is required  releasing the
Mortgagor  from  liability on the  Non-Designated  Mortgage  Loan,  such Servicer  shall prepare and deliver or
cause to be prepared and delivered to the Trustee for signature  and shall direct,  in writing,  the Trustee to
execute the  assumption  agreement  with the Person to whom the  Mortgaged  Property is to be conveyed and such
modification  agreement or supplement to the Mortgage Note or Mortgage or other  instruments  as are reasonable
or  necessary  to carry out the  terms of the  Mortgage  Note or  Mortgage  or  otherwise  to  comply  with any
applicable laws regarding  assumptions or the transfer of the Mortgaged  Property to such Person. In connection
with any such  assumption,  no  material  term of the  Mortgage  Note may be changed.  Together  with each such
substitution,  assumption or other  agreement or  instrument  delivered to the Trustee for execution by it, the
related  Servicer  shall  deliver an  Officer's  Certificate  signed by a Servicing  Officer  stating  that the
requirements of this subsection have been met in connection  therewith.  The related  Servicer shall notify the
Trustee and the Trust  Administrator  that any such substitution or assumption  agreement has been completed by
forwarding to the Trustee and the Trust  Administrator  a copy of such  substitution  or assumption  agreement,
and shall  forward the original to the Custodian  which shall be added to the related  Mortgage File and shall,
for all purposes,  be  considered a part of such  Mortgage  File to the same extent as all other  documents and
instruments  constituting  a part  thereof.  Any fee collected by a Servicer for entering into an assumption or
substitution of liability agreement will be retained by such Servicer as additional servicing compensation.

SECTION 3.11.  Realization Upon Defaulted Mortgage Loans; Repurchase of Certain Mortgage Loans.

(a)     Each  Servicer  shall use  reasonable  efforts to foreclose  upon or otherwise  comparably  convert the
ownership of properties  securing such of the related  Non-Designated  Mortgage Loans as come into and continue
in default and as to which no  satisfactory  arrangements  can be made for  collection of delinquent  payments.
In connection  with such  foreclosure  or other  conversion,  each Servicer  shall take such action as (i) such
Servicer  would take under  similar  circumstances  with  respect to a similar  mortgage  loan held for its own
account for investment,  (ii) shall be consistent with Accepted Servicing Practices,  (iii) such Servicer shall
determine  consistently  with  Accepted  Servicing  Practices  to be in the  best  interest  of the  Trust  and
Certificateholders,  and (iv) is  consistent with the requirements of the insurer under any Required  Insurance
Policy;  provided,  however,  that such  Servicer  shall not be required to expend its own funds in  connection
with any  foreclosure  or towards the  restoration  of any property  unless it shall  determine  (i) that  such
restoration  and/or  foreclosure  will  increase  the  proceeds of  liquidation  of the related  Non-Designated
Mortgage Loan after  reimbursement  to itself of such expenses and (ii) that  such expenses will be recoverable
to  it   through   Liquidation   Proceeds.   Any   funds   expended   by  any   Servicer   pursuant   to   this
Section 3.11(a) shall be reimbursable in full pursuant to  Section 3.08(a)(iii).  The related Servicer shall be
responsible for all other costs and expenses incurred by it in any such proceedings;  provided,  however,  that
it shall be entitled  to  reimbursement  thereof  from the  Liquidation  Proceeds  with  respect to the related
Mortgaged Property or otherwise as a Servicing Advance in accordance with Section 3.08(a).

               With  respect to any  Non-Designated  Mortgage  Loan,  notwithstanding  anything to the contrary
contained in this  Agreement,  in connection with a foreclosure or acceptance of a deed in lieu of foreclosure,
in the event the related  Servicer  has  reasonable  cause to believe  that the related  Mortgaged  Property is
contaminated by hazardous or toxic substances or wastes, or if the Trust Administrator  otherwise requests,  an
environmental  inspection or review of such  Mortgaged  Property  conducted by a qualified  inspector  shall be
arranged for by such Servicer.  Upon completion of the inspection,  the related Servicer shall promptly provide
the Trust Administrator with a written report of environmental inspection.

               In the event the  environmental  inspection  report  indicates  that the  Mortgaged  Property is
contaminated  by  hazardous  or toxic  substances  or wastes,  the  related  Servicer  shall not  proceed  with
foreclosure or acceptance of a deed in lieu of foreclosure if the estimated  costs of the  environmental  clean
up, as estimated in the  environmental  inspection  report,  together with the Servicing  Advances and Advances
made by such Servicer and the estimated  costs of  foreclosure  or acceptance of a deed in lieu of  foreclosure
exceeds  the  estimated  value of the  Mortgaged  Property.  If  however,  the  aggregate  of such clean up and
foreclosure  costs,  Advances  and  Servicing  Advances  are less than or equal to the  estimated  value of the
Mortgaged  Property,  then the related Servicer may, in its reasonable judgment and in accordance with Accepted
Servicing  Practices,  choose to proceed with  foreclosure or acceptance of a deed in lieu of  foreclosure  and
such Servicer shall be reimbursed for all reasonable  costs  associated with such  foreclosure or acceptance of
a deed in lieu of foreclosure and any related  environmental  clean up costs,  as applicable,  from the related
Liquidation  Proceeds,  or if the Liquidation Proceeds are insufficient to fully reimburse such Servicer,  such
Servicer  shall be  entitled  to be  reimbursed  from  amounts in the related  Collection  Account  pursuant to
Section 3.08(a) hereof.  In the event the related  Servicer does not proceed with  foreclosure or acceptance of
a deed in lieu of  foreclosure  pursuant  to the first  sentence  of this  paragraph,  such  Servicer  shall be
reimbursed  for all Advances and Servicing  Advances made with respect to the related  Mortgaged  Property from
the related  Collection  Account  pursuant to  Section 3.08(a) hereof,  and such Servicer shall have no further
obligation to service such Non-Designated Mortgage Loan under the provisions of this Agreement.

(b)     With respect to any REO Property related to a Non-Designated  Mortgage Loan, the deed or certificate of
sale  shall,  subject  to  applicable  laws,  be  taken  in the  name of the  Trustee  for the  benefit  of the
Certificateholders,  or its nominee,  on behalf of the  Certificateholders.  The Trustee's name shall be placed
on the title to such  REO Property  solely as the Trustee  hereunder and not in its  individual  capacity.  The
related  Servicer shall ensure that the title to such  REO Property  references  this Agreement and the Trustee
capacity  hereunder.  Pursuant  to its  efforts  to sell  such  REO Property,  the  related  Servicer  shall in
accordance with Accepted Servicing  Practices manage,  conserve,  protect and operate each REO Property for the
purpose of its prompt  disposition and sale. The related  Servicer,  either itself or through an agent selected
by such  Servicer,  shall manage,  conserve,  protect and operate the  REO Property  in the same manner that it
manages,  conserves,  protects  and operates  other  foreclosed  property for its own account,  and in the same
manner that similar  property in the same locality as the  REO Property is managed.  Upon request,  the related
Servicer  shall  furnish to the Trust  Administrator  on or before  each  Distribution  Date a  statement  with
respect to any REO Property  covering the operation of such  REO Property  for the previous  calendar month and
such Servicer's  efforts in connection with the sale of such  REO Property and any rental of such  REO Property
incidental to the sale thereof for the previous  calendar  month.  That statement  shall be accompanied by such
other  information as the Trust  Administrator  shall  reasonably  request and which is necessary to enable the
Trust  Administrator  to comply  with the  reporting  requirements  of the REMIC  Provisions.  The net  monthly
rental income, if any, from such  REO Property  shall be deposited in the related  Collection  Account no later
than the close of business on each  Determination  Date.  The related  Servicer shall perform the tax reporting
and  withholding  required  by  Sections  1445  and  6050J  of  the  Code  with  respect  to  foreclosures  and
abandonments,  the tax reporting  required by Section 6050H of the Code with respect to the receipt of mortgage
interest from  individuals  and any tax  reporting  required by  Section 6050P  of the Code with respect to the
cancellation of indebtedness by certain financial  entities,  by preparing such tax and information  returns as
may be required, in the form required, and delivering the same to the Trust Administrator for filing.

               To the extent  consistent with Accepted  Servicing  Practices,  the related  Servicer shall also
maintain  on each  REO Property  related  to a  Non-Designated  Mortgage  Loan fire and hazard  insurance  with
extended  coverage  in an  amount  which  is  equal  to  the  outstanding  principal  balance  of  the  related
Non-Designated  Mortgage  Loan (as reduced by any amount  applied as a reduction  of  principal  at the time of
acquisition  of the  REO Property),  liability  insurance and, to the extent  required and available  under the
Flood Disaster Protection Act of 1973, as amended, flood insurance in the amount required above.

(c)     In the event that the Trust  Fund  acquires  any  Mortgaged  Property  as  aforesaid  or  otherwise  in
connection  with a default or imminent  default on a Mortgage Loan, the related  Servicer shall dispose of such
Mortgaged  Property  prior to three years after the end of the calendar  year of its  acquisition  by the Trust
Fund unless  (i) the  Trustee and the Trust  Administrator  shall have been supplied with an Opinion of Counsel
to the effect that the  holding by the Trust Fund of such  Mortgaged  Property  subsequent  to such  three-year
period will not result in the  imposition  of taxes on  "prohibited  transactions"  of any REMIC  hereunder  as
defined  in  section  860F of the Code or cause any REMIC  hereunder  to fail to qualify as a REMIC at any time
that any  Certificates  are  outstanding,  in which case the Trust  Fund may  continue  to hold such  Mortgaged
Property  (subject to any  conditions  contained  in such Opinion of Counsel) or (ii) the  applicable  Servicer
shall have applied for,  prior to the expiration of such  three-year  period,  an extension of such  three-year
period in the manner contemplated by  Section 856(e)(3)  of the Code, in which case the three-year period shall
be extended by the applicable  extension  period.  Notwithstanding  any other provision of this  Agreement,  no
Mortgaged  Property  acquired  by the Trust  Fund  shall be rented (or  allowed  to  continue  to be rented) or
otherwise  used for the  production of income by or on behalf of the Trust Fund in such a manner or pursuant to
any terms that would  (i) cause such Mortgaged  Property to fail to qualify as  "foreclosure  property"  within
the meaning of section  860G(a)(8) of the Code or  (ii) subject  any REMIC  hereunder to the  imposition of any
federal,   state  or  local  income  taxes  on  the  income   earned  from  such   Mortgaged   Property   under
Section 860G(c) of  the Code or  otherwise,  unless  the  related  Servicer  has agreed to  indemnify  and hold
harmless the Trust Fund with respect to the imposition of any such taxes.

               In the event of a  default  on a  Mortgage  Loan one or more of whose  obligors  is not a United
States Person, as that term is defined in  Section 7701(a)(30)  of the Code, in connection with any foreclosure
or  acquisition of a deed in lieu of foreclosure  (together,  "foreclosure")  in respect of such Mortgage Loan,
the related  Servicer will cause compliance with the provisions of Treasury  Regulation  Section 1.1445-2(d)(3)
(or any successor  thereto)  necessary to assure that no withholding tax obligation  arises with respect to the
proceeds of such  foreclosure  except to the extent,  if any, that proceeds of such foreclosure are required to
be remitted to the obligors on such Mortgage Loan.

(d)     The decision of a Servicer to foreclose on a defaulted  Non-Designated  Mortgage  Loan shall be subject
to a determination by such Servicer that the proceeds of such  foreclosure  would exceed the costs and expenses
of  bringing  such a  proceeding.  The  income  earned  from  the  management  of any  REO  Properties,  net of
reimbursement  to such  Servicer for expenses  incurred  (including  any property or other taxes) in connection
with such management and net of applicable  accrued and unpaid  Servicing Fees, and  unreimbursed  Advances and
Servicing  Advances,  shall be applied to the payment of  principal  of and  interest on the related  defaulted
Non-Designated  Mortgage Loans (with interest accruing as though such Non-Designated  Mortgage Loans were still
current) and all such income shall be deemed,  for all  purposes in this  Agreement,  to be payments on account
of principal  and interest on the related  Mortgage  Notes and shall be deposited  into the related  Collection
Account.  To the  extent  the net  income  received  during  any  calendar  month is in  excess  of the  amount
attributable  to  amortizing  principal  and  accrued  interest  at the  related  Mortgage  Rate on the related
Non-Designated  Mortgage  Loan for such  calendar  month,  such  excess  shall be  considered  to be a  partial
prepayment of principal of the related Non-Designated Mortgage Loan.

(e)     The proceeds  from any  liquidation  of a  Non-Designated  Mortgage  Loan, as well as any income from a
related  REO Property,  will be applied in the  following  order of priority:  first,  to reimburse the related
Servicer for any related  unreimbursed  Servicing Advances and Servicing Fees, and with respect to Wells Fargo,
any  REO  Disposition  Fees  related  to such  Mortgage  Loan;  second,  to  reimburse  such  Servicer  for any
unreimbursed Advances;  third, to reimburse the related Collection Account for any Nonrecoverable  Advances (or
portions  thereof)  that were  previously  withdrawn  by such  Servicer  pursuant to  Section 3.08(a)(iii) that
related to such  Non-Designated  Mortgage  Loan;  fourth,  to accrued  and  unpaid  interest  (to the extent no
Advance has been made for such amount or any such Advance has been reimbursed) on the  Non-Designated  Mortgage
Loan or related  REO Property,  at the per annum rate equal to the related Mortgage Rate reduced by the related
Servicing Fee Rate,  and any primary  mortgage  guaranty  insurance fee rate,  if  applicable,  to the Due Date
occurring  in the month in which such  amounts are  required  to be  distributed;  and fifth,  as a recovery of
principal of the Mortgage Loan.  Excess  proceeds,  if any, from the liquidation of a Liquidated  Mortgage Loan
("Excess  Proceeds")  that is a  Non-Designated  Mortgage  Loan will be  retained  by the  related  Servicer as

exists,  unless the  Non-Designated  Mortgage Loan is liquidated and the proceeds  thereof are deposited in the
related  Collection  Account,  in which case such  Servicer  shall  deliver to the Trustee,  or the Custodian a
Request  for  Release  in the  form  of  Exhibit K,  signed  by a  Servicing  Officer.  Each  Servicer  is also
authorized to cause the removal from the  registration  on the MERS® System of such Mortgage and to execute and
deliver,  on behalf of the  Trustee  and the  Certificateholders  or any of them,  any and all  instruments  of
satisfaction  or  cancellation  or of partial or full  release,  including  an  assignment  of such loan to the
Trustee.

               If a  Servicer  at any time  seeks to  initiate  a  foreclosure  proceeding  in  respect  of any
Mortgaged  Property  related to a Non-Designated  Mortgage Loan as authorized by this Agreement,  such Servicer
shall deliver or cause to be delivered to the Trustee,  for signature,  as  appropriate,  any court  pleadings,
requests for trustee's sale or other  documents  necessary to effectuate  such  foreclosure or any legal action
brought  to  obtain  judgment  against  the  Mortgagor  on the  Mortgage  Note or the  Mortgage  or to obtain a
deficiency  judgment or to enforce any other  remedies or rights  provided by the Mortgage Note or the Mortgage

Mortgage Loans,  whether from the collection of principal and interest  payments or from Liquidation  Proceeds,
including  but not  limited  to, any funds on deposit in a  Collection  Account,  shall be held by the  related
Servicer  for and on behalf of the Trust,  the Trustee or the Trust  Administrator  and shall be and remain the
sole and  exclusive  property  of the Trust,  subject to the  applicable  provisions  of this  Agreement.  Each
Servicer  also  agrees  that it shall not  create,  incur or subject  any  Mortgage  File or any funds that are
deposited in the related Collection  Account,  Certificate  Account or any related Escrow Account, or any funds
that otherwise are or may become due or payable to the Trust,  the Trustee or the Trust  Administrator  for the
benefit of the Certificateholders,  to any claim, lien, security interest,  judgment,  levy, writ of attachment
or other  encumbrance,  or  assert by legal  action or  otherwise  any  claim or right of  setoff  against  any
Mortgage  File or any funds  collected on, or in  connection  with, a  Non-Designated  Mortgage  Loan,  except,
however,  that such  Servicer  shall be  entitled to set off against and deduct from any such funds any amounts
that are properly due and payable to such Servicer under this Agreement.

Serviced  Mortgage Loan as its  compensation  and Ancillary  Income with respect to Special  Serviced  Mortgage
Loans.

(b)     With respect to each Non-Designated  Mortgage Loan,  additional  servicing  compensation in the form of

compensation in the form of Payoff  Interest not required to make payments in respect of Compensating  Interest
Payments  shall be retained by SPS and additional  servicing  compensation  in the form of Prepayment  Interest

connection  with any  Subservicing  Agreement  entered  into  pursuant to  Section 3.02  and the payment of any
premiums for insurance  required pursuant to Section 3.18)  and shall not be entitled to reimbursement  thereof
except as specifically provided for in this Agreement.

(c)     The Master Servicer shall be compensated by the Trust  Administrator as separately  agreed.  The Master

relating to (a) this  Agreement,  (b) the  Certificates or (c) the  performance of any of the Master Servicer's
duties  hereunder,  other than any loss,  liability or expense incurred by reason of willful  misfeasance,  bad
faith or negligence in the performance of any of the Master  Servicer's  duties hereunder or incurred by reason
of any action of the Master  Servicer  taken at the  direction of the  Certificateholders;  provided,  however,
that the sum of (x) such  indemnity  amounts payable by DLJMC or the Trust to the Master  Servicer  pursuant to
this  Section 3.14(c) and  (y) the indemnity  amounts payable by DLJMC or the Trust to the Trust  Administrator
pursuant  to  Section 10.05,  shall not exceed  $200,000  per year;  provided,  further,  that any  amounts not
payable by DLJMC or the Trust to the Master  Servicer due to the  preceding  proviso  shall be payable by DLJMC
(or if DLJMC  fails to do so, by the Trust) in any  succeeding  year,  subject to the  aggregate  $200,000  per
annum  limitation  imposed by the preceding  proviso.  Such  indemnity  shall survive the  termination  of this
Agreement or the resignation or removal of the Master Servicer hereunder.

agents of the OTS,  the FDIC and such other  authorities,  access to the  documentation  regarding  the related
Non-Designated  Mortgage  Loans required by applicable  regulations of the OTS and the FDIC.  Such access shall
be afforded  without  charge,  but only upon  reasonable and prior written  request and during normal  business
hours at the offices designated by the Master Servicer or such Servicer.  Nothing in this  Section shall  limit
the obligation of the Master Servicer or any Servicer to observe any applicable law  prohibiting  disclosure of
information  regarding  the  Mortgagors  and the  failure of the Master  Servicer  or such  Servicer to provide
access as  provided  in this  Section as  a result of such  obligation  shall not  constitute  a breach of this
Section.  Nothing in this  Section 3.15  shall require the Master Servicer or any Servicer to collect,  create,
collate or otherwise generate any information that it does not generate in its usual course of business.

"Transferring  Servicer")  shall  transfer  the  servicing of any Mortgage  Loan  serviced by the  Transferring
Servicer  which is 90 days or more  delinquent  (determined  as of the close of business of the last day of the
month  preceding  the related  Data  Remittance  Date) to the Special  Servicer.  The  Special  Servicer  shall
thereupon assume all of the rights and obligations of the Transferring  Servicer  hereunder arising  thereafter
and the  Transferring  Servicer  shall have no further  rights or  obligations  hereunder  with respect to such
Mortgage  Loan  (except  that the  Special  Servicer  shall not be  (i) liable  for losses of the  Transferring
Servicer pursuant to Section 3.09  hereof or for any acts or omissions of the Transferring  Servicer  hereunder

Loans  hereunder  including,  but not limited to,  repurchases or  substitutions  of Mortgage Loans pursuant to
Section 2.02  or 2.03 hereof,  (iii) deemed to have made any  representations  and warranties of a Transferring
Servicer  hereunder or (iv) be subject to any other agreement not executed by the Special  Servicer).  Upon the
transfer of the servicing of any such  Mortgage Loan to the Special  Servicer,  the Special  Servicer  shall be
entitled to the related Servicing Fee and other  compensation  accruing after the servicing  transfer date with
respect to such Mortgage Loans pursuant to Section 3.14.

               In connection  with the transfer of the servicing of any Mortgage Loan to the Special  Servicer,
the  Transferring  Servicer,  at the Special  Servicer's  expense,  shall  deliver to the Special  Servicer all
documents  and records  relating to such Mortgage  Loans and an  accounting of amounts  collected or held by it
and  otherwise  use its best  efforts to effect the orderly and  efficient  transfer  of the  servicing  to the
Special  Servicer.  On the servicing  transfer date,  the Special  Servicer  shall  reimburse the  Transferring
Servicer for all unreimbursed Advances,  Servicing Advances and Servicing Fees, as applicable,  relating to the
Mortgage  Loans for which the  servicing is being  transferred.  The Special  Servicer  shall be entitled to be
reimbursed  pursuant to Section 3.08 or otherwise  pursuant to this Agreement for all such Advances,  Servicing
Advances and Servicing Fees, as applicable,  paid by the Transferring  Servicer pursuant to this  Section 3.19.
In addition,  the Special  Servicer shall notify the Master Servicer of such transfer and the effective date of
such transfer,  and amend the Mortgage Loan Schedule to reflect that such Mortgage  Loans are Special  Serviced
Mortgage Loans.

SECTION 3.20.  Indemnification of Servicers and Master Servicer.

               Each  Servicer  agrees to indemnify and hold the Master  Servicer  harmless from and against any
and all losses, claims,  expenses,  costs or liabilities (including attorneys fees and court costs) incurred by
the  Master  Servicer  as a result of or in  connection  with the  failure  by such  Servicer  to  perform  the
obligations or responsibilities imposed upon or undertaken by such Servicer under this Agreement.

Mortgage Note.  The related  Servicer  shall execute and deliver any and all necessary  notices  required under
applicable  law and  the  terms  of the  related  Mortgage  Note  and  Mortgage  regarding  the  Mortgage  Rate
adjustments.   Upon  the  discovery  by  the  related  Servicer  or  the  receipt  of  notice  from  the  Trust
Administrator  that such  Servicer  has failed to adjust a Mortgage  Rate in  accordance  with the terms of the
related Mortgage Note, such Servicer shall  immediately  deposit in the Certificate  Account from its own funds
the amount of any interest loss or deferral caused the Trust Administrator thereby.

SECTION 3.22.  Designated Mortgage Loans.

(a)     For and on behalf of the  Certificateholders,  the  Master  Servicer  shall  oversee  and  enforce  the
obligation of each  Designated  Servicer to service and  administer  the related  Designated  Mortgage Loans in
accordance  with the  terms of the  related  Designated  Servicing  Agreement  and shall  have  full  power and
authority to do any and all things which it may deem  necessary  or  desirable in  connection  with such master
servicing and  administration.  In performing its  obligations  hereunder,  the Master  Servicer shall act in a
manner  consistent with this Agreement and with customary and usual  standards of practice of prudent  mortgage
loan master  servicers.  Furthermore,  the Master  Servicer  shall  oversee and  consult  with each  Designated
Servicer as necessary from time-to-time to carry out the Master  Servicer's  obligations  hereunder,  and shall
receive,  review and evaluate all reports,  information  and other data provided to the Master Servicer by each
Designated Servicer.

               The Master Servicer shall terminate the rights and obligations of any Designated  Servicer under
the related  Designated  Servicing  Agreement,  upon the failure of such Designated  Servicer to perform any of
its obligations  under such  Designated  Servicing  Agreement,  which failure results in an event of default as
provided in Section 8.01 of the IndyMac Underlying  Servicing  Agreement,  with respect to IndyMac, as provided
in  Section 9.01  of the GMAC  Mortgage  Underlying  Servicing  Agreement,  with respect to GMAC  Mortgage,  as
provided in Section 14 of the Countrywide  Underlying  Servicing  Agreement,  with respect to  Countrywide,  as
provided in  Section 8.01  of the  EverBank  Underlying  Servicing  Agreement,  with respect to EverBank and as
provided in Section 8.01 of the First Horizon  Underlying  Servicing  Agreement  with respect to First Horizon.
In the event a Designated  Servicer is  terminated  pursuant to the  preceding  sentence,  the Master  Servicer
shall notify the  Depositor  and the Trust  Administrator  and shall either  (a) select  and engage a successor
servicer of the related  Mortgage  Loans or (b) act as successor  servicer of the related  Mortgage  Loans.  In
either case, the Designated  Mortgage Loans related to such  Designated  Servicing  Agreement shall be serviced
by the successor to such Designated Servicer pursuant to the servicing  provisions of this Agreement,  and such
Designated  Mortgage Loans shall be deemed as "Non-Designated  Mortgage Loans" under this Agreement;  provided,
however,  it is understood  and  acknowledged  by the parties  hereto that there will be a period of transition
(not to exceed 90 days)  before the actual  servicing  functions  can be fully  transferred  to such  successor
Designated  Servicer.  Such  enforcement,  including,  without  limitation,  the legal  prosecution  of claims,
termination of Designated  Servicing  Agreements  and the pursuit of other  appropriate  remedies,  shall be in
such  form and  carried  out to such an extent  and at such  time as the  Master  Servicer,  in its good  faith
business  judgment,  would require were it the owner of the related  Mortgage Loans.  The Master Servicer shall
pay the costs of such  enforcement at its own expense,  provided that the Master Servicer shall not be required
to prosecute  or defend any legal  action  except to the extent that the Master  Servicer  shall have  received
reasonable indemnity for its costs and expenses in pursuing such action.

               To the extent that the costs and expenses of the Master  Servicer  related to any termination of
a Designated  Servicer,  appointment  of a successor  Designated  Servicer or the transfer  and  assumption  of
servicing by the Master  Servicer  with  respect to any  Designated  Servicing  Agreement  (including,  without
limitation,  (i) all  legal costs and expenses and all due  diligence  costs and  expenses  associated  with an
evaluation of the  potential  termination  of a Designated  Servicer as a result of an event of default by such
Designated  Servicer  and (ii) all  costs and expenses  associated  with the  complete  transfer of  servicing,
including all servicing  files and all servicing data and the  completion,  correction or  manipulation of such
servicing  data as may be required by the successor  servicer to correct any errors or  insufficiencies  in the
servicing data or otherwise to enable the successor  servicer to service the Mortgage Loans in accordance  with
this Agreement) are not fully reimbursed by the terminated  Designated  Servicer,  the Master Servicer shall be
entitled to reimbursement of such costs and expenses from the Trust.

(b)     Each month,  if a  Designated  Servicer  fails to make a required  Advance by the date such  Advance is
required to be made under the related  Designated  Servicing  Agreement,  the Master Servicer shall on the Cash
Remittance Date deposit in the amount of any required Advance in the Certificate Account.

(c)     Each  month,  the Master  Servicer  shall  make  Compensating  Interest  Payments  with  respect to the
Designated Mortgage Loans to the extent provided in Section 3.03.

SECTION 3.23.  Assigned Prepayment Premiums.

               Notwithstanding  anything  in this  Agreement  to the  contrary,  in the  event  of a  Principal
Prepayment,  the applicable  Servicer may not waive any Assigned Prepayment Premium or portion thereof required
by the terms of the related  Mortgage Note unless  (i) the  related  Mortgage Loan is in default or foreseeable
default and such waiver  (a) is  standard and  customary in servicing  mortgage  loans  similar to the Mortgage
Loans and (b) would,  in the reasonable  judgment of such Servicer,  maximize recovery of total proceeds taking
into  account the value of such  Assigned  Prepayment  Premium  and the related  Mortgage  Loan,  (ii) (A)  the
enforceability thereof is limited (1) by bankruptcy,  insolvency,  moratorium,  receivership,  or other similar
law relating to creditors'  rights  generally or (2) due to  acceleration  in connection  with a foreclosure or
other  involuntary  payment,  or (B) the  enforceability  is otherwise limited or prohibited by applicable law,
(iii) the  enforceability  would be  considered  "predatory"  pursuant  to  written  guidelines  issued  by any
applicable  federal,  state or local authority having  jurisdiction over such matters, or (iv) such Servicer is
unable to locate  documentation  sufficient  to allow it to confirm the  existence  and amount of such Assigned
Prepayment Premium after using  commercially  reasonable  efforts to locate such  documentation,  which efforts
shall  include,  but are not limited  to,  seeking  such  documentation  from the  Depositor,  the Seller,  the
Custodian and from its own records or files.  For the  avoidance of doubt,  the  applicable  Servicer may waive
an Assigned  Prepayment  Premium in connection with a short sale or short payoff on a defaulted  Mortgage Loan.
If an  applicable  Servicer  has  waived all or a portion  of an  Assigned  Prepayment  Premium  relating  to a
Principal  Prepayment,  other than as provided above, such Servicer shall deliver to the Trust Administrator no
later than the next  succeeding Cash  Remittance  Date, for deposit into the Certificate  Account the amount of
such Assigned  Prepayment  Premium (or such portion thereof as had been waived) for  distribution in accordance
with the  terms of this  Agreement  and if such  Servicer  fails  to  deliver  such  amount,  any of the  Trust
Administrator,  the Master Servicer,  the Trustee or the Seller may enforce such  obligation.  If such Servicer
has  waived  all or a  portion  of an  Assigned  Prepayment  Premium  for any  reason,  it shall  include  such
information in any monthly reports it provides,  and such Servicer if other than Wells Fargo Bank,  N.A., shall
notify the Trust  Administrator,  the Seller,  the Master Servicer and the Trustee of such waiver,  and if such
Servicer is Wells Fargo Bank, N.A., Wells Fargo Bank, N.A. shall notify the Trust  Administrator  and the Trust
Administrator   shall  forward  any  such  notice  to  the  Seller,   the  Master  Servicer  and  the  Trustee.
Notwithstanding  any provision in this Agreement to the contrary,  in the event the Assigned Prepayment Premium
payable  under the  terms of the  related  Mortgage  Note is less than the  amount of the  Assigned  Prepayment
Premium set forth in the Mortgage  Loan  Schedule or other  information  provided to the  applicable  Servicer,
such  Servicer  shall not have any  liability  or  obligation  with  respect  to such  difference.  The  Master
Servicer  shall not have any  responsibility  for verifying  the accuracy of the amount of Assigned  Prepayment
Premiums remitted by the Servicers.

               Notwithstanding  anything  in  this  Agreement  to the  contrary,  the  Trustee  and  the  Trust
Administrator  shall  have no  obligation  to collect  Prepayment  Premiums  from any  Servicer  or  Designated
Servicer other than Wells Fargo,  in its capacity as a Servicer (or any of its successors and assigns),  or SPS
(or any of its successors and assigns).

Group for such Distribution Date and (ii) (A) after the Special Hazard Coverage  Termination Date, with respect

Amount for each Class of  Class C-B  Certificates with respect to Loan Group 1,  Loan Group 2,  Loan Group 3 or
Loan  Group 4  such  reduction  shall be based on the amount of interest  accruing at the Net WAC Rate for such
Loan  Group on  such  Class's  proportionate  share,  based  on the  Class  Principal  Balance  of the  related
Subordinate Component Balance for that Distribution Date.

               (C)    With respect to each Class of  Class C-B  Certificates,  if on any Distribution  Date the

distribution of Principal  Prepayments  will be made to any Class or Classes of Class C-B  Certificates  junior
to such Class (the  "Restricted  Classes") and the amount otherwise  distributable to the Restricted Classes in
respect  of  such  Principal   Prepayments  will  be  allocated  among  the  remaining   Classes  of  Class C-B
Certificates, pro rata, based upon their respective Class Principal Balances.

Optional  Termination of Loan Group 1,  Loan Group 2,  Loan Group 3 and Loan Group 4 in excess of the Par Value

Certificates on the Distribution Date in the next calendar month as follows:

(i)     any Realized Loss, other than an Excess Loss, shall be allocated first, to the Class C-B  Certificates,
        in  decreasing  order of  their  alphanumerical  Class designations  (beginning  with  the  Class C-B-6
        Certificates),  until the  respective  Class  Principal  Balance of each such Class has been reduced to
        zero, and second, to the Senior  Certificates of the related  Certificate Group, pro rata, on the basis
        of their respective  Class Principal  Balances,  until the respective  Class Principal  Balance of each
        such  Class has  been reduced to zero;  provided,  however,  with respect to the Group 1  Certificates,
        Realized Losses on the Group 1 Loans that would otherwise be allocated to the Class 1-A-1  Certificates
        and  Class 1-A-2  Certificates  in the aggregate will instead be allocated  first,  to the  Class 1-A-2
        Certificates,  until  its  Class  Principal  Balance  has been  reduced  to zero,  and  second,  to the
        Class 1-A-1 Certificates,  until its Class Principal Balance has been reduced to zero, and with respect
        to the Group 4 Certificates,  Realized Losses on the Group 4 Loans that would otherwise be allocated to
        the Class 4-A-1  Certificates  and Class 4-A-2  Certificates in the aggregate will instead be allocated
        first, to the Class 4-A-2 Certificates,  until its Class Principal Balance has been reduced to zero and
        second,  to the Class 4-A-1  Certificates,  until its Class Principal Balance has been reduced to zero;
        and

(ii)    Excess Losses in respect of principal for Mortgage  Loans in Loan Group 1,  Loan Group 2,  Loan Group 3
        and Loan  Group 4  will be  allocated  among all  Group 1,  Group 2,  Group 3,  Group 4  and  Class C-B
        Certificates, pro rata based on their respective Class Principal Balances.

(b)     On each Distribution Date, if the aggregate Class Principal Balance of all Group 1,  Group 2,  Group 3,
Group 4 and Class C-B  Certificates  exceeds the Aggregate  Groups 1-4  Collateral Balance (after giving effect
to  distributions  of principal and the  allocation  of all losses to such  Certificates  on such  Distribution
Date),  such excess will be deemed a principal  loss and will be  allocated by the Trust  Administrator  to the
most junior Class of Class C-B Certificates then outstanding.

(c)     Any Realized Loss allocated to a Class of  Certificates or any reduction in the Class Principal Balance
of a Class of  Certificates  pursuant to  Section 4.02(b) shall  be allocated by the Trust  Administrator among
the Certificates of such Class in proportion to their respective Certificate Balances.

(d)     Any allocation by the Trust  Administrator  of Realized Losses to a Certificate or any reduction in the
Certificate  Balance of a  Certificate  pursuant to  Section 4.02(b) shall  be  accomplished  by  reducing  the
Certificate Balance thereof,  immediately  following the distributions made on the related Distribution Date in
accordance with the definition of "Certificate Balance."

(e)     On each Distribution Date, the Trust  Administrator  shall determine the total Applied Loss Amount with
respect to the  Group 5  Certificates,  if any,  for such  Distribution  Date.  The  Applied  Loss  Amount with
respect  to the  Group 5  Certificates  for any  Distribution  Date  shall be  applied  by  reducing  the Class
Principal Balance of each Class of Class M  Certificates and the Class 5-A-2  Certificates,  beginning with the
Class of Class M  Certificates,  then outstanding with the lowest relative payment  priority,  or if no Class M
Certificates  are then  outstanding,  the  Class 5-A-2  Certificates,  in each case until the respective  Class
Principal  Balance  thereof  has been  reduced to zero.  Any Applied  Loss  Amount with  respect to the Group 5
Certificates  allocated  to a Class of Class M  Certificates  or  Class 5-A-2  Certificates  shall be allocated
among the Class M Certificates of such Class or the Class 5-A-2  Certificates,  as applicable, in proportion to
their respective Percentage Interests.

(f)     All Realized Losses on the Group 1,  Group 2,  Group 3 and Group 4 Mortgage Loans shall be allocated on
each  Distribution  Date to the REMIC I  Regular  Interests as provided in the  definition of REMIC I  Realized
Losses.

(g)     All Realized Losses on the Group 5 Mortgage Loans shall be allocated on each  Distribution  Date to the
REMIC II Regular Interests as provided in the definition of REMIC II Realized Losses.

(h)     Realized  Losses on the  Group 5  Mortgage  Loans that are not  Applied  Loss  Amounts  shall be deemed
allocated to the Class 5-X  Certificates.  Realized Losses  allocated to the Class 5-X  Certificates  shall, be
allocated  between the REMIC III  Regular Interests 5-X-IO and 5-X-PO as provided in the definition of Realized
Losses.

(i)     Realized  Losses shall be allocated  among the REMIC I,  REMIC II and  REMIC III  Regular  Interests as

definitions of REMIC I Realized Losses and REMIC II Realized Losses, respectively.

SECTION 4.03.  Recoveries.

(a)     With  respect  to any  Class of  Certificates  to which a  Realized  Loss or Applied  Loss  Amount,  as
applicable,  has been allocated  (including any such Class for  which the related Class  Principal  Balance has
been  reduced to zero),  the Class  Principal  Balance of such  Class will  be  increased,  up to the amount of
related Recoveries for such Distribution Date as follows:

(i)     with respect to Recoveries on Group 1, Group 2, Group 3 and Group 4, Mortgage Loans,

(A)     first, the Class Principal Balance of each Class of Senior Certificates  related to the Loan Group from
               which the Recovery was  collected,  will be increased pro rata, up to the amount of Net Recovery
               Realized Losses for each such Class, and

(B)     second, the Class Principal Balance of each Class of Class C-B  Certificates will be increased in order

(ii)    with respect to Recoveries on Group 5  Mortgage Loans,  the Class Principal  Balance of the Class 5-A-2
        Certificates and each Class of Class M Certificates will be increased in order of seniority,  up to the
        Deferred Amount such Class is entitled to receive pursuant to Section 4.01(II)(d) on  such Distribution
        Date prior to giving effect to payments pursuant to Section 4.01(II)(d) on such Distribution Date.

               The  Master  Servicer,  with  respect  to  the  Mortgage  Loans,  shall  provide  to  the  Trust
Administrator the information set forth in Exhibit H in such form as the Trust  Administrator  shall reasonably

SECTION 4.07.  Cross-Collateralization; Adjustments to Available Funds.

(a)     On each  Distribution  Date prior to the Class C-B Credit Support Depletion Date, but after the date on
which the aggregate Class Principal Balance of the Group 1,  Group 2,  Group 3 or Group 4 Certificates has been
reduced to zero,  the Trust  Administrator  shall  distribute the principal  portion of Available  Distribution
Amount on the Mortgage  Loans  relating to such Senior  Certificates  that will have been paid in full,  to the
holders of the Senior  Certificates of the other  Certificate  Group(s).  Such amount will be allocated between
the other Groups,  pro rata, based on aggregate Class Principal Balance of the related Senior  Certificates and
paid the Senior  Certificates in each such Group in the same priority as such Certificates  would receive other
distributions of principal pursuant to  Section 4.01(I)(A);  provided,  however,  that the Trust  Administrator
shall  not  make  such  distribution  on such  Distribution  Date if  (a) the  Class C-B  Percentage  for  such
Distribution  Date is greater  than or equal to 200% of such  Class C-B  Percentage  as of the Closing Date and
(b) the average outstanding  principal balance of the Mortgage Loans in each Loan  Group delinquent  60 days or
more over the last six months, as a percentage of the related Subordinate Component Balance, is less than 50%.

(b)     If on any Distribution Date the aggregate Class Principal Balance of the Group 1,  Group 2,  Group 3 or
Group 4  Certificates  is greater than the Aggregate  Loan Group Balance of the related Loan  Group (each  Loan
Group related to such Group of  Certificates,  an  "Undercollateralized  Group"),  then the Trust Administrator
shall reduce the  Available  Distribution  Amount of the other Loan  Group(s)  that is not  undercollateralized
(each, an "Overcollateralized Group"), as follows:

(1)     to add to the Available Distribution Amount of the Undercollateralized  Group(s) an amount equal to the
        lesser of  (a) one  month's  interest  on the  Principal  Transfer  Amount  of the  Undercollateralized
        Group(s)  at the  Net  WAC  Rate  applicable  to the  Undercollateralized  Group(s)  and  (b) Available
        Distribution Amount of the  Overcollateralized  Groups remaining after making interest distributions to
        the Senior  Certificates  of the  Overcollateralized  Group(s) on such  Distribution  Date  pursuant to
        Section 4.01; and

(2)     to the Senior  Certificates of each  Undercollateralized  Group, to the extent of the principal portion
        of Available  Distribution  Amount of the  Overcollateralized  Group(s) remaining after making interest
        and principal  distributions  to the Senior  Certificates  of the  Overcollateralized  Group(s) on such
        Distribution  Date  pursuant  to  Section 4.01,  until  the  Class  Principal  Balance  of  the  Senior
        Certificates  of such  Undercollateralized  Group(s)  equals the  Aggregate  Loan Group  Balance of the
        related Loan  Group(s).  Payments  shall be made to the Senior  Certificates  in each Group in the same
        priority  as  such   Certificates   would  receive  other   distributions  of  principal   pursuant  to
        Section 4.01(I)(A).

(c)     If more than one Overcollateralized  Group exists on any Distribution Date, reductions in the Available
Distribution  Amount of such Groups to make the  payments  required to be made  pursuant to  Section 4.07(b) on
such  Distribution  Date  shall  be  made  pro  rata,  based  on  the  Overcollateralization   Amount  of  each
Overcollateralized  Group.  If  more  than  one  Undercollateralized  Group exists  on any  Distribution  Date,
payments made to such Groups from the Available  Distribution Amount of the  Overcollateralized  Group shall be
made pro rata, based on the amount of payments required to be made to the Undercollateralized Group(s).

SECTION 4.10.  Group 5 Interest Rate Cap Account.

(a)     On the Closing Date,  the Trust  Administrator  shall  establish and maintain in its name, in trust for

Interest Rate Cap Account  shall be an Eligible  Account,  and funds on deposit  therein shall be held separate
and apart from,  and shall not be  commingled  with,  any other moneys,  including  without  limitation,  other
moneys held by the Trust Administrator pursuant to this Agreement.

(b)     On each  Distribution  Date on and after the Distribution Date in November 2005 and on and prior to the
Distribution Date in September 2010,  the Trust  Administrator shall deposit any amounts paid under the Group 5
Interest  Rate Cap  Agreement  into the Group 5  Interest Rate Cap Account.  On each  Distribution  Date on and
after the Distribution Date in November 2005 and on and prior to the Distribution Date in  September 2010,  the
Trust  Administrator  shall  distribute  amounts on deposit in the Group 5  Interest Rate Cap Account to pay to
the  Group 5  Certificates,  any  applicable  Basis  Risk  Shortfalls,  prior to giving  effect to any  amounts
available to be paid in respect of related  Basis Risk  Shortfalls  as described in  Section 4.01(II)(d)(vi) on
such Distribution Date

(c)     On any  Distribution  Date  amounts  on deposit  in the  Group 5  Interest  Rate Cap  Account  shall be

(iii)   to the  Principal  Remittance  Amount  for Loan  Group 5,  up to the amount of  Realized  Losses on the
        Mortgage Loans in such Loan  Group incurred  during the related  Collection Period, any shortfall to be
        allocated pro rata based upon the amount of such Realized Losses applicable to such Loan Group; and

(iv)    sequentially, to the Class 5-A-2,  Class 5-M-1,  Class 5-M-2,  Class 5-M-3, Class 5-M-4 and Class 5-M-5
        Certificates,  in that order, any applicable Deferred Amounts,  with interest therein at the applicable
        Pass-Through  Rate,  prior to giving  effect to amounts  available  to be paid in  respect of  Deferred
        Amounts as described in Section 4.01(II)(d)(ii)-(vi) on such Distribution Date.

(d)     Funds in the Group 5  Interest  Rate Cap Account may be invested in Eligible  Investments  by the Trust
Administrator  at the  direction  of the  Depositor  maturing on or prior to the next  succeeding  Distribution

fund within the meaning of Treasury  regulation  1.860G-2(h) and  not an asset of any REMIC created pursuant to
this Agreement.  The Trust  Administrator  shall treat amounts paid by the Group 5 Interest Rate Cap Account as
payments  made from  outside the REMIC's for all Federal  tax  purposes.  Any net  investment  earnings on such
amounts shall be payable to the  Depositor.  The Depositor  will be the owner of the Group 5  Interest Rate Cap
Account for federal tax purposes and the Depositor  shall direct the Trust  Administrator  in writing as to the
investment of amounts  therein.  In the absence of such written  direction,  all funds in the Group 5  Interest
Rate Cap Account  may be invested by the Trust  Administrator  in the Wells Fargo  Advantage  Prime  Investment
Money  Market  Fund or any  successor  fund.  The Trust  Administrator  shall have no  liability  for losses on
investments in Eligible  Investments made pursuant to this  Section 4.10(c) (other  than as obligor on any such
investments).  Upon  termination  of the Trust Fund,  any amounts  remaining in the Group 5  Interest  Rate Cap
Account shall be distributed to the Class 5-X Certificateholders.

(e)     On the  Distribution  Date  immediately  after  the  Distribution  Date on which  the  aggregate  Class
Principal Balance of the Group 5  Certificates equals zero, any amounts on deposit in the Group 5 Interest Rate
Cap Account not payable on the Group 5 Certificates shall be distributed to the Class 5-X Certificateholders.

(f)     Amounts  paid under the  Group 5  Interest  Rate Cap  Agreement  not used on any  Distribution  Date as
described  in  Section 4.10(b) shall  remain on deposit in the  Group 5  Interest  Rate Cap  Account and may be
available on future  Distribution  Dates to make the  payments  described in  Section 4.10(b).  However,  at no
time shall the amount on deposit in the Group 5  Interest Rate Cap Account exceed the related  Deposit  Amount.
The  "Deposit  Amount"  with  respect to the Group 5  Interest  Rate Cap  Account  will be  calculated  on each
Distribution  Date,  after giving  effect to  withdrawals  from the Group 5  Interest  Rate Cap Account on such
Distribution Date and  distributions  and allocation of losses on the Certificates on such  Distribution  Date,
and will equal the excess,  if any, of the Targeted  Overcollateralization  Amount for such  Distribution  Date
over the  Overcollateralization  Amount  for such  Distribution  Date.  On each  Distribution  Date,  the Trust
Administrator  shall  distribute  amounts in the  Group 5  Interest  Rate Cap  Account in excess of the related
Deposit Amount to the Class 5-X Certificateholders.

(g)     The Trustee is hereby directed,  on or prior to the Closing Date, on behalf of the Trust, to enter into
the Group 5  Interest  Rate Cap Agreement  for the benefit of the Holders of the Group 5  Certificates,  in the
form  presented  to it by the  Depositor.  The  Trustee  shall not have any  responsibility  for the  contents,
adequacy or  sufficiency  of the Group 5  Interest  Rate Cap  Agreement,  including,  without  limitation,  any
representations and warranties contained therein.

                                 ADVANCES BY THE MASTER SERVICER AND SERVICERS

SECTION 5.01.  Advances by the Master Servicer and Servicers.

               With respect to the  Non-Designated  Mortgage Loans,  each Servicer shall deposit in the related
Collection  Account as Advances an amount equal to all Scheduled  Payments  (with interest at the Mortgage Rate
less the Servicing Fee Rate) which were due on such  Non-Designated  Mortgage  Loans  serviced by it during the
applicable  Collection  Period and which were delinquent at the close of business on the immediately  preceding
Determination  Date;  provided,  however,  that with  respect to any  Balloon  Loan that is  delinquent  on its
maturity date, a Servicer will not be required to advance the related  balloon  payment but will be required to
continue to make Advances in accordance with this  Section 5.01  with respect to such Balloon Loan in an amount
equal to an assumed scheduled payment that would otherwise be due based on the original  amortization  schedule
for that Mortgage  Loan (with  interest at the Mortgage  Rate less the  Servicing  Fee Rate).  Each  Servicer's
obligation to make such  Advances as to any related  Non-Designated  Mortgage  Loan will  continue  through the
last Scheduled  Payment due prior to the payment in full of such  Non-Designated  Mortgage Loan, or through the
date that the related  Mortgaged  Property  has,  in the  judgment of the  related  Servicer,  been  completely
liquidated.  Each  Servicer  shall not be required to advance  shortfalls  of principal  or interest  resulting
from the application of the Relief Act.

               With respect to any  Non-Designated  Mortgage Loan, to the extent required by Accepted Servicing
Practices,  the Master  Servicer and each Servicer  shall be obligated to make Advances in accordance  with the
provisions  of  this  Agreement;   provided,  however,  that  such  obligation  with  respect  to  any  related
Non-Designated  Mortgage Loan shall cease if the Master  Servicer or a Servicer  determines,  in its reasonable
opinion,  that Advances with respect to such Non-Designated  Mortgage Loan are Nonrecoverable  Advances. In the
event  that  the  Master  Servicer  or such  Servicer  determines  that any such  Advances  are  Nonrecoverable
Advances,  the Master  Servicer or such  Servicer  shall  provide the Trust  Administrator  with a  certificate
signed by a Servicing Officer evidencing such determination.

               With respect to any  Non-Designated  Mortgage  Loan,  if the amount of Advances  received from a
Servicer  is less than the amount  required  to be  advanced by such  Servicer,  the Master  Servicer  shall be
obligated to make a payment in an amount equal to such deficiency,  subject to any  determination by the Master
Servicer that any portion of the amount required to be advanced is a Nonrecoverable Advance.

               With respect to any of the  Non-Designated  Mortgage Loans, if an Advance is required to be made
hereunder by a Servicer,  such Servicer shall on the Cash Remittance Date either  (i) deposit in the Collection
Account from its own funds an amount equal to such Advance,  (ii) cause to be made an appropriate  entry in the
records of the Collection  Account that funds in such account being held for future  distribution or withdrawal
have been,  as  permitted  by this  Section 5.01,  used by such  Servicer  to make such  Advance or  (iii) make
Advances in the form of any combination of clauses  (i) and  (ii) aggregating  the amount of such Advance.  Any
such funds being held in a  Collection  Account for future  distribution  and so used shall be replaced by such
Servicer from its own funds by deposit in such  Collection  Account on or before any future  Distribution  Date
in which  such  funds  would be due or from  other  funds in such  Collection  Account  being  held for  future
distribution at that time.

               With  respect to any  Designated  Mortgage  Loan,  the Master  Servicer  shall make  Advances as
required by Section 3.22(b) of this Agreement.

                                                  ARTICLE VI

                                               THE CERTIFICATES

SECTION 6.01.  The Certificates.

               The Certificates  shall be in  substantially  the forms set forth in Exhibits A, B, C, D-1, D-2,
E, F and G hereto,  with such  appropriate  insertions,  omissions,  substitutions  and other variations as are
required or permitted by this  Agreement or as may in the  reasonable  judgment of the Trust  Administrator  or
the Depositor be necessary,  appropriate or convenient to comply,  or facilitate  compliance,  with  applicable
laws,  and may have such letters,  numbers or other marks of  identification  and such legends or  endorsements
placed  thereon as may be  required  to comply  with the rules of any  securities  exchange on which any of the
Certificates may be listed,  or as may,  consistently  herewith,  be determined by the officers  executing such
Certificates, as evidenced by their execution thereof.

               Subject  to  Section 11.03  respecting  the  final  distribution  on the  Certificates,  on each
Distribution Date the Trust Administrator shall make distributions to each  Certificateholder  of record on the
preceding  Record  Date either  (x) by wire  transfer  in  immediately  available  funds to the account of such
holder at a bank or other entity having  appropriate  facilities  therefor,  if (i) such Holder has so notified
the Trust  Administrator  at least five  Business Days prior to the related  Record Date and  (ii) such  Holder
shall  hold (A) a  Notional  Amount  Certificate,  (B) 100% of the  Class  Principal  Balance  of any  Class of
Certificates  or  (c) Certificates  of any  Class with  aggregate  principal  Denominations  of not  less  than
$1,000,000 or (y) by check mailed by first class mail to such  Certificateholder  at the address of such holder
appearing in the Certificate Register.

               The definitive Certificates shall be printed, typewritten,  lithographed or engraved or produced
by any  combination  of these  methods or may be produced  in any other  manner  permitted  by the rules of any
securities  exchange  on which  any of the  Certificates  may be  listed,  all as  determined  by the  officers
executing such Certificates, as evidenced by their execution thereof.

               The Certificates  shall be issuable in registered form, in the minimum  denominations,  integral
multiples in excess thereof  (except that one  Certificate  in each  Class may be issued in a different  amount
which must be in excess of the  applicable  minimum  denomination)  and aggregate  denominations  per Class set
forth in the Preliminary Statement.

               The  Certificates  shall be executed  by manual or  facsimile  signature  on behalf of the Trust
Administrator  by  a  Responsible  Officer.   Certificates  bearing  the  manual  or  facsimile  signatures  of
individuals  who were,  at the time when such  signatures  were  affixed,  authorized  to sign on behalf of the
Trust Administrator shall bind the Trust  Administrator,  notwithstanding  that such individuals or any of them
have ceased to be so authorized prior to the  authentication  and delivery of such Certificates or did not hold
such  offices at the date of such  Certificate.  No  Certificate  shall be entitled  to any benefit  under this
Agreement,  or be  valid  for  any  purpose,  unless  there  appears  on  such  Certificate  a  certificate  of
authentication   executed  by  the  Trust   Administrator  by  manual   signature,   and  such  certificate  of
authentication  upon  any  Certificate  shall  be  conclusive  evidence,  and  the  only  evidence,  that  such
Certificate has been duly  authenticated and delivered  hereunder.  All Certificates shall be dated the date of
their authentication.

SECTION 6.02.  Registration of Transfer and Exchange of Certificates.

(a)     The Trust Administrator  shall maintain,  or cause to be maintained,  a Certificate  Register in which,
subject to such  reasonable  regulations as it may  prescribe,  the Trust  Administrator  shall provide for the
registration  of  Certificates  and of  transfers  and  exchanges  of  Certificates  as herein  provided.  Upon
surrender  for  registration  of  transfer  of  any  Certificate,   the  Trust   Administrator  shall  execute,
authenticate  and  deliver,  in the  name  of the  designated  transferee  or  transferees,  one  or  more  new
Certificates in like aggregate interest and of the same Class.

(b)     At the  option  of a  Certificateholder,  Certificates  may be  exchanged  for  other  Certificates  of
authorized  denominations  and the same  aggregate  interest  in the  Trust  Fund and of the same  Class,  upon
surrender of the Certificates to be exchanged at the office or agency of the Trust  Administrator  set forth in
Section 6.06.  Whenever any  Certificates  are so  surrendered  for  exchange,  the Trust  Administrator  shall
execute,  authenticate  and  deliver  the  Certificates  which the  Certificateholder  making the  exchange  is
entitled to receive.  Every  Certificate  presented or  surrendered  for  registration  of transfer or exchange
shall be accompanied by a written  instrument of transfer in form satisfactory to the Trust  Administrator duly
executed by the Holder thereof or his attorney duly authorized in writing.

(c)     No service charge to the Certificateholders  shall be made for any registration of transfer or exchange
of  Certificates,  but payment of a sum sufficient to cover any tax or governmental  charge that may be imposed
in connection with any transfer or exchange of Certificates may be required.

(d)     All  Certificates  surrendered  for  registration  of  transfer  and  exchange  shall be  canceled  and
subsequently  destroyed by the Trust  Administrator  in  accordance  with the Trust  Administrator's  customary
procedures.

(e)     No transfer  of any Private  Certificate  shall be made  unless  that  transfer is made  pursuant to an
effective  registration  statement  under  the 1933  Act and  effective  registration  or  qualification  under
applicable  state  securities  laws, or is made in a transaction  which does not require such  registration  or
qualification.  Except in  connection  with any  transfer  of a Private  Certificate  by the  Depositor  to any
affiliate or any transfer of a Private  Certificate  from the  Depositor or an affiliate of the Depositor to an
owner  trust or other  entity  established  by the  Depositor,  in the event that a  transfer  is to be made in
reliance  upon an exemption  from the 1933 Act and such laws, in order to assure  compliance  with the 1933 Act
and  such  laws,  the  Certificateholder   desiring  to  effect  such  transfer  and  such  Certificateholder's
prospective  transferee  shall each certify to the Trust  Administrator  in writing the facts  surrounding  the
transfer in  substantially  the form set forth in Exhibit L (the  "Transferor  Certificate")  and (i) deliver a
letter in  substantially  the form of either (A) Exhibit M-1 (the  "Investment  Letter"),  provided that all of
the Private  Certificates of a Class shall be transferred to one investor or the Depositor  otherwise  consents
to such transfer,  or  (B) Exhibit M-2  (the "Rule 144A  Letter") or (ii) there shall be delivered to the Trust
Administrator  at the expense of the  transferor  an Opinion of Counsel that such transfer may be made pursuant
to an exemption  from the 1933 Act. The  Depositor  shall  provide to any Holder of a Private  Certificate  and
any prospective  transferee  designated by any such Holder,  information regarding the related Certificates and
the Mortgage  Loans and such other  information  as shall be necessary to satisfy the condition to  eligibility
set forth in Rule 144A(d)(4) for transfer of any such Certificate without  registration  thereof under the 1933
Act pursuant to the  registration  exemption  provided by Rule 144A.  The Trust  Administrator  shall cooperate
with the Depositor in providing  the Rule 144A  information  referenced  in the preceding  sentence,  including
providing to the Depositor such information  regarding the  Certificates,  the Mortgage Loans and other matters
regarding the Trust Fund as the Depositor shall  reasonably  request to meet its obligation under the preceding
sentence.  Each Holder of a Private  Certificate  desiring to effect such transfer shall, and does hereby agree
to, indemnify the Trust Administrator,  the Depositor,  the Seller, the Master Servicer,  each Servicer and the
Special  Servicer  against  any  liability  that may result if the  transfer is not so exempt or is not made in
accordance with such federal and state laws.

(f)     Except in connection  with any transfer of a Private  Certificate  by the Depositor to any affiliate or
any transfer of a Private  Certificate  from the  Depositor or an affiliate of the  Depositor to an owner trust
or other entity established by the Depositor,  no transfer of an  ERISA-Restricted  Certificate (except for the
Residual  Certificates)  shall be made unless the Trust  Administrator  shall have received in accordance  with
Exhibit M-1 or  Exhibit M-2,  as  applicable,  either (i) a  representation  letter from the transferee of such
Certificate,  acceptable to and in form and substance  satisfactory to the Trust  Administrator,  to the effect
that such  transferee  is not an  employee  benefit  plan or  arrangement  subject to  Section 406  of ERISA or
Section 4975  of the Code, or a person using the assets of any such plan or arrangement,  which  representation
letter  shall not be an  expense  of the  Trustee,  the Trust  Administrator  or the Trust  Fund,  (ii) if  the
purchaser  is  an  insurance  company  and  the  Certificate  has  been  the  subject  of  an  ERISA-Qualifying
Underwriting,  a  representation  that  the  purchaser  is  an  insurance  company  which  is  purchasing  such
Certificates  with funds  contained  in an  "insurance  company  general  account"  (as such term is defined in
Section V(e) of  Prohibited  Transaction  Class Exemption  95-60  ("PTCE  95-60"))  and that the  purchase  and
holding of such  Certificates  are covered  under  Sections I and III of PTCE 95-60 or (iii) in the case of any
such Certificate  presented for registration in the name of an employee benefit plan or arrangement  subject to
Section 406 of ERISA or Section 4975 of the Code (or comparable  provisions of any subsequent  enactments),  or
a person  using  such  plan's  or  arrangement's  assets,  an  Opinion  of  Counsel  satisfactory  to the Trust
Administrator  to the effect that the  purchase or holding of such  Certificate  will not result in  prohibited
transactions  under  Section 406 of ERISA and/or  Section 4975  of the Code and will not subject the Depositor,
the Trustee, the Trust  Administrator,  the Master Servicer or any other Servicer to any obligation in addition
to those  undertaken  in this  Agreement,  which  Opinion of Counsel shall not be an expense of such parties or
the Trust Fund.  No  transfer of a Residual  Certificate  shall be made  unless the Trust  Administrator  shall
have received,  in accordance with Exhibit N,  a representation letter from the transferee of such Certificate,
acceptable  to and in form and  substance  satisfactory  to the Trust  Administrator,  to the effect  that such
transferee is not an employee  benefit plan or arrangement  subject to Section 406 of ERISA or  Section 4975 of
the Code, or a person using the assets of any such plan or arrangement,  which representation  letter shall not
be an expense of the  Trustee,  the Trust  Administrator  or the Trust Fund.  In the event the  representations
referred to in this  Section 6.02(f) are not furnished,  such representations shall be deemed to have been made
to the trustee by the  transferee's  acceptance of such  ERISA-Restricted  Certificate by any beneficial  owner
who  purchases an interest in such  Certificate  in  book-entry  form.  In the event that a  representation  is
violated,  or any attempt to transfer an ERISA-Restricted  Certificate to a plan or arrangement or person using
a plan's or arrangement's  assets is attempted  without the delivery to the Trust  Administrator of the Opinion
of Counsel  described above, the attempted  transfer or acquisition of such Certificate shall be void and of no
effect.

(g)     Additional restrictions on transfers of the Class AR and Class AR-L Certificates are set forth below:

(i)     Each Person who has or who acquires any ownership  interest in a Residual  Certificate  shall be deemed
        by the  acceptance  or  acquisition  of such  ownership  interest  to have  agreed  to be  bound by the
        following  provisions and to have irrevocably  authorized the Trust Administrator or its designee under
        clause  (iii)(A)  below to deliver  payments to a Person  other than such Person and to  negotiate  the
        terms of any mandatory sale under clause  (iii)(B) below and to execute all instruments of transfer and
        to do all other things  necessary in connection with any such sale. The rights of each Person acquiring
        any ownership interest in a Residual Certificate are expressly subject to the following provisions:

(A)     Each Person holding or acquiring any ownership  interest in a Residual  Certificate shall be other than
           a Disqualified  Organization  and shall  promptly  notify the Trust  Administrator  of any change or
           impending change in its status as other than a Disqualified Organization.

(B)     In connection with any proposed transfer of any ownership interest in a Residual  Certificate to a U.S.
           Person,  the Trust  Administrator  shall require delivery to it, and shall not register the transfer
           of a Residual  Certificate  until its  receipt of (1) an  affidavit  and  agreement  (a  "Transferee
           Affidavit and Agreement"  attached  hereto as Exhibit N) from the proposed  transferee,  in form and
           substance  satisfactory  to the  Trust  Administrator,  representing  and  warranting,  among  other
           things,  that it is not a non  U.S.  Person,  that  such  transferee  is other  than a  Disqualified
           Organization,  that it is not  acquiring its ownership  interest in a Residual  Certificate  that is
           the  subject  of the  proposed  Transfer  as a  nominee,  trustee or agent for any Person who is not
           other than a Disqualified  Organization,  that for so long as it retains its ownership interest in a
           Residual Certificate,  it will endeavor to remain other than a Disqualified  Organization,  and that
           it has reviewed the  provisions of this  Section 6.02(g) and  agrees to be bound by them,  and (2) a
           certificate,  attached  hereto  as  Exhibit O,  from the  Holder  wishing  to  transfer  a  Residual
           Certificate,  in form and  substance  satisfactory  to the  Trust  Administrator,  representing  and
           warranting,  among other  things,  that no purpose of the proposed  transfer is to allow such Holder
           to impede the assessment or collection of tax.

(C)     Notwithstanding  the delivery of a Transferee  Affidavit and Agreement by a proposed  transferee  under
           clause (B) above, if the Trust  Administrator  has actual knowledge that the proposed  transferee is
           not other than a  Disqualified  Organization,  no  transfer of an  ownership  interest in a Residual
           Certificate to such proposed transferee shall be effected.

(D)     Each Person holding or acquiring any ownership  interest in a Residual  Certificate  agrees, by holding
           or acquiring  such  ownership  interest,  to require a Transferee  Affidavit and Agreement  from the
           other  Person to whom such Person  attempts  to transfer  its  ownership  interest  and to provide a
           certificate to the Trust Administrator in the form attached hereto as Exhibit O.

(ii)    The Trust Administrator  shall register the transfer of any Residual  Certificate only if it shall have
        received the Transferee  Affidavit and Agreement,  a certificate of the Holder requesting such transfer
        in the form attached  hereto as Exhibit O and all of such other documents as shall have been reasonably
        required by the Trust Administrator as a condition to such registration.

(iii)   (A)If any  Disqualified  Organization  shall become a Holder of a Residual  Certificate,  then the last
           preceding Holder that was other than a Disqualified  Organization  shall be restored,  to the extent
           permitted  by law,  to all rights  and  obligations  as Holder  thereof  retroactive  to the date of
           registration of such transfer of such Residual  Certificate.  If any non U.S. Person  shall become a
           Holder of a Residual  Certificate,  then the last  preceding  Holder that is a U.S.  Person shall be
           restored,  to the  extent  permitted  by law,  to all  rights  and  obligations  as  Holder  thereof
           retroactive  to the date of  registration  of the transfer to such non U.S.  Person of such Residual
           Certificate.  If a transfer of a Residual  Certificate is disregarded  pursuant to the provisions of
           Treasury Regulations  Section 1.860E-1 or Section 1.860G-3,  then the last preceding Holder that was
           other than a Disqualified  Organization  shall be restored,  to the extent  permitted by law, to all
           rights and  obligations as Holder thereof  retroactive to the date of  registration of such transfer
           of such  Residual  Certificate.  The Trust  Administrator  shall be under no liability to any Person
           for any  registration  of transfer of a Residual  Certificate  that is in fact not permitted by this
           Section 6.02(g) or  for making any payments  due on such  Certificate  to the Holder  thereof or for
           taking any other action with respect to such Holder under the provisions of this Agreement.

                             (B)    If any  purported  transferee  of a  Residual  Certificate  shall  become a
           Holder of a Residual  Certificate in violation of the  restrictions in this  Section 6.02(g) and  to
           the  extent  that  the  retroactive  restoration  of the  rights  of the  Holder  of  such  Residual
           Certificate as described in clause (iii)(A) above shall be invalid,  illegal or unenforceable,  then
           the  Depositor  shall  have the  right,  without  notice to the  Holder or any prior  Holder of such
           Residual  Certificate,  to sell such Residual  Certificate to a purchaser  selected by the Depositor
           on such terms as the Depositor may choose.  Such purported  transferee  shall  promptly  endorse and
           deliver  a  Residual  Certificate  in  accordance  with  the  instructions  of the  Depositor.  Such
           purchaser  may be the  Depositor  itself or any  affiliate  of the  Depositor.  The proceeds of such
           sale,  net of the  commissions  (which  may  include  commissions  payable to the  Depositor  or its
           affiliates),  expenses and taxes due, if any,  shall be remitted by the Depositor to such  purported
           transferee.  The terms and  conditions  of any sale under this clause  (iii)(B)  shall be determined
           in the sole  discretion  of the  Depositor,  and the  Depositor  shall not be  liable to any  Person
           having an  ownership  interest or a purported  ownership  interest  in a Residual  Certificate  as a
           result of its exercise of such discretion.

(iv)    The Master  Servicer and each Servicer,  on behalf of the Trust  Administrator,  shall make  available,
        upon written request from the Trust Administrator,  all information  reasonably available to it that is
        necessary  to compute  any tax imposed (A) as a result of the  transfer of an  ownership  interest in a
        Residual  Certificate  to any Person who is not other than a Disqualified  Organization,  including the
        information  regarding "excess inclusions" of such Residual  Certificate required to be provided to the
        Internal  Revenue  Service and certain  Persons as  described  in  Treasury  Regulation  Section 1.860D
        1(b)(5), and (B) as a result of any regulated investment company,  real estate investment trust, common
        trust fund,  partnership,  trust, estate or organizations  described in Section 1381 of the Code having
        as among its record holders at any time any Person who is not other than a  Disqualified  Organization.
        Reasonable  compensation  for providing such  information may be required by the Master Servicer or the
        related Servicer from such Person.

(v)     The provisions of this  Section 6.02(g) set  forth prior to this Section (v) may be modified,  added to
        or  eliminated  by the  Depositor,  provided  that  there  shall  have  been  delivered  to  the  Trust
        Administrator the following:

(A)     written  notification  from each  Rating  Agency to the effect  that the  modification,  addition to or
           elimination  of such  provisions  will not cause such Rating  Agency to  downgrade  its then current
           rating of the Certificates; and

(B)     a certificate of the Depositor  stating that the Depositor has received an Opinion of Counsel,  in form
           and substance  satisfactory to the Depositor,  to the effect that such modification,  addition to or
           elimination  of such  provisions  will not cause the Trust  Fund to cease to  qualify as a REMIC and
           will not create a risk that  (i) the  Trust Fund may be subject to an entity level tax caused by the
           transfer of a Residual  Certificate to a Person which is not other than a Disqualified  Organization
           or (2) a  Certificateholder  or another  Person will be subject to a REMIC related tax caused by the
           transfer of  applicable  Residual  Certificate  to a Person  which is not other than a  Disqualified
           Organization.

(vi)    The following legend shall appear on each Residual Certificate:

           ANY RESALE,  TRANSFER OR OTHER  DISPOSITION OF THIS CERTIFICATE MAY BE MADE ONLY IF THE PROPOSED
           TRANSFEREE  PROVIDES A TRANSFER AFFIDAVIT TO THE DEPOSITOR AND THE TRUST  ADMINISTRATOR THAT (1)
           SUCH TRANSFEREE IS NOT (A) THE UNITED STATES, ANY STATE OR POLITICAL  SUBDIVISION  THEREOF,  ANY
           FOREIGN GOVERNMENT, ANY INTERNATIONAL  ORGANIZATION,  OR ANY AGENCY OR INSTRUMENTALITY OF ANY OF
           THE FOREGOING,  (B) ANY ORGANIZATION  (OTHER THAN A COOPERATIVE  DESCRIBED IN SECTION 521 OF THE
           CODE) WHICH IS EXEMPT FROM THE TAX IMPOSED BY CHAPTER 1 OF THE CODE UNLESS SUCH  ORGANIZATION IS
           SUBJECT  TO THE TAX  IMPOSED BY  SECTION  511 OF THE CODE,  (C) ANY  ORGANIZATION  DESCRIBED  IN
           SECTION  1381(a)(2)(C) OF THE CODE (ANY SUCH PERSON DESCRIBED IN THE FOREGOING CLAUSES (A), (B),
           OR (C) BEING  HEREINAFTER  REFERRED TO AS A "DISQUALIFIED  ORGANIZATION"),  OR (D) AN AGENT OF A
           DISQUALIFIED  ORGANIZATION  AND (2) NO PURPOSE OF SUCH  TRANSFER IS TO ENABLE THE  TRANSFEROR TO
           IMPEDE  THE   ASSESSMENT  OR  COLLECTION  OF  TAX.   SUCH   AFFIDAVIT   SHALL  INCLUDE   CERTAIN
           REPRESENTATIONS AS TO THE FINANCIAL  CONDITION OF THE PROPOSED  TRANSFEREE.  NOTWITHSTANDING THE
           REGISTRATION  IN THE  CERTIFICATE  REGISTER OF ANY TRANSFER,  SALE OR OTHER  DISPOSITION OF THIS
           CERTIFICATE TO A DISQUALIFIED  ORGANIZATION  OR AN AGENT OF A  DISQUALIFIED  ORGANIZATION,  SUCH
           REGISTRATION  SHALL BE DEEMED TO BE OF NO LEGAL FORCE OR EFFECT WHATSOEVER AND SUCH PERSON SHALL
           NOT BE DEEMED TO BE A CERTIFICATEHOLDER  FOR ANY PURPOSE HEREUNDER,  INCLUDING,  BUT NOT LIMITED
           TO, THE  RECEIPT OF  DISTRIBUTIONS  ON THIS  CERTIFICATE.  EACH  HOLDER OF THIS  CERTIFICATE  BY
           ACCEPTANCE  OF THIS  CERTIFICATE  SHALL BE DEEMED TO HAVE  CONSENTED TO THE  PROVISIONS  OF THIS
           PARAGRAPH.

(h)     The Trust  Administrator  shall have no liability to the Trust Fund arising from a transfer of any such
Certificate  in reliance upon a  certification,  ruling or Opinion of Counsel  described in this  Section 6.02;
provided,  however,  that the Trust Administrator  shall not register the transfer of any Residual  Certificate
if it has actual  knowledge  that the  proposed  transferee  does not meet the  qualifications  of a  permitted
Holder of a Residual Certificate as set forth in this Section 6.02.

SECTION 6.03.  Mutilated, Destroyed, Lost or Stolen Certificates.

               If  (a) any  mutilated  Certificate  is  surrendered  to the Trust  Administrator,  or the Trust
Administrator  receives  evidence to its satisfaction of the destruction,  loss or theft of any Certificate and
(b) there is delivered to each  Servicer,  the Trustee and the Trust  Administrator  such security or indemnity
as may be required  by them to save each of them  harmless,  then,  in the absence of notice to the Trustee and
the  Trust  Administrator  that  such  Certificate  has been  acquired  by a  protected  purchaser,  the  Trust
Administrator  shall  execute,  authenticate  and deliver,  in exchange  for or in lieu of any such  mutilated,
destroyed,  lost or stolen  Certificate,  a new  Certificate  of like tenor and interest in the Trust Fund.  In
connection  with the issuance of any new  Certificate  under this  Section 6.03,  the Trust  Administrator  may
require the payment of a sum  sufficient to cover any tax or other  governmental  charge that may be imposed in
relation  thereto  and any  other  expenses  (including  the  fees and  expenses  of the  Trust  Administrator)
connected  therewith.  Any  replacement  Certificate  issued  pursuant to this  Section 6.03  shall  constitute
complete and  indefeasible  evidence of ownership in the Trust Fund,  as if originally  issued,  whether or not
the lost, stolen or destroyed Certificate shall be found at any time.

SECTION 6.04.  Persons Deemed Owners.

               Prior to due  presentation of a Certificate for  registration  of transfer,  each Servicer,  the
Trust  Administrator,  and any agent of the Master Servicer or any Servicer,  the Trust Administrator may treat
the person in whose name any  Certificate  is  registered as the owner of such  Certificate  for the purpose of
receiving  distributions as provided in this Agreement and for all other purposes  whatsoever,  and none of the
Master Servicer or the Servicers,  the Trust Administrator,  nor any agent of the Master Servicer or a Servicer
or the Trust Administrator shall be affected by any notice to the contrary.

SECTION 6.05.  Access to List of Certificateholders' Names and Addresses.

(a)     If three or more  Certificateholders  (i) request in writing from the Trust Administrator a list of the
names and addresses of Certificateholders,  (ii) state that such Certificateholders  desire to communicate with
other  Certificateholders  with  respect to their rights under this  Agreement  or under the  Certificates  and
(iii) provide a copy of the communication  which such  Certificateholders  propose to transmit,  then the Trust
Administrator   shall,   within  ten   Business   Days  after  the  receipt  of  such   request,   afford  such
Certificateholders  access  during  normal  business  hours to a current  list of the  Certificateholders.  The
expense  of  providing  any  such  information  requested  by  a  Certificateholder   shall  be  borne  by  the
Certificateholders  requesting  such  information  and  shall not be borne by the  Trust  Administrator  or the
Trustee.  Every  Certificateholder,  by receiving  and holding a  Certificate,  agrees that the Trustee and the
Trust  Administrator  shall not be held  accountable by reason of the disclosure of any such  information as to
the list of the  Certificateholders  hereunder,  regardless  of the  source  from which  such  information  was
derived.

(b)     The Master Servicer and each Servicer,  so long as it is a servicer hereunder,  DLJMC and the Depositor
shall have  unlimited  access to a list of the names and addresses of the  Certificateholders  which list shall
be provided by the Trust Administrator promptly upon request.

SECTION 6.06.  Maintenance of Office or Agency.

               The Trust  Administrator  will  maintain or cause to be  maintained  at its expense an office or
offices  or  agency  or  agencies  in  Minneapolis,   Minnesota  where  Certificates  may  be  surrendered  for
registration  of transfer  or exchange  and where  notices  and demands to or upon the Trust  Administrator  in
respect of the  Certificates and this Agreement may be served.  The Trust  Administrator  initially  designates
its Corporate  Trust Office as its office for such purpose.  The Trust  Administrator  will give prompt written
notice to the Certificateholders of any change in the location of any such office or agency.

SECTION 6.07.  Book Entry Certificates.

               Notwithstanding the foregoing,  the Book-Entry  Certificates,  upon original issuance,  shall be
issued in the form of one or more  typewritten  Certificates  representing the Book-Entry  Certificates,  to be
delivered  to  DTC,  the  initial  Clearing  Agency,  by,  or on  behalf  of,  the  Depositor.  The  Book-Entry
Certificates  shall initially be registered on the Certificate  Register in the name of Cede & Co., the nominee
of DTC, as the  initial  Clearing  Agency,  and no  Beneficial  Holder will  receive a  definitive  certificate
representing  such  Beneficial  Holder's  interest in the  Certificates,  except as  provided in  Section 6.09.
Unless and until definitive,  fully registered  Certificates  ("Definitive  Certificates")  have been issued to
the Beneficial Holders pursuant to Section 6.09:

(a)     the  provisions of this  Section 6.07  shall be in full force and effect with respect to the Book-Entry
Certificates;

(b)     the  Depositor  and the Trust  Administrator  may deal with the Clearing  Agency for all purposes  with
respect to the Book-Entry  Certificates  (including the making of  distributions  on such  Certificates) as the
sole Holder of such Certificates;

(c)     to the extent that the  provisions  of this  Section 6.07  conflict  with any other  provisions of this
Agreement, the provisions of this Section 6.07 shall control; and

(d)     the rights of the  Beneficial  Holders of the Book-Entry  Certificates  shall be exercised only through
the  Clearing  Agency and the  Participants  and shall be limited to those  established  by law and  agreements
between such  Beneficial  Holders and the Clearing Agency and/or the  Participants.  Pursuant to the Depository
Agreement,  unless and until Definitive Certificates are issued pursuant to Section 6.09,  the initial Clearing
Agency  will make  book-entry  transfers  among the  Participants  and receive and  transmit  distributions  of
principal and interest on the related Book-Entry Certificates to such Participants.

               For  purposes of any  provision  of this  Agreement  requiring  or  permitting  actions with the
consent of, or at the direction of, Holders of the Book-Entry  Certificates  evidencing a specified  percentage
of the aggregate unpaid principal  amount of such  Certificates,  such direction or consent may be given by the
Clearing  Agency at the direction of  Beneficial  Holders  owning such  Certificates  evidencing  the requisite
percentage of principal  amount of such  Certificates.  The Clearing Agency may take  conflicting  actions with
respect to the  Book-Entry  Certificates  to the extent that such actions are taken on behalf of the Beneficial
Holders.

SECTION 6.08.  Notices to Clearing Agency.

               Whenever  notice or other  communication  to the Holders of Book-Entry  Certificates is required
under  this  Agreement,  unless  and  until  Definitive  Certificates  shall  have been  issued to the  related
Certificateholders  pursuant  to  Section 6.09,  the  Trust  Administrator  shall  give  all such  notices  and
communications  specified  herein to be given to Holders of the Book-Entry  Certificates to the Clearing Agency
which  shall  give  such  notices  and  communications  to the  related  Participants  in  accordance  with its
applicable rules, regulations and procedures.

SECTION 6.09.  Definitive Certificates.

               If (a) the Depositor  advises the Trust  Administrator in writing that the Clearing Agency is no
longer willing or able to properly discharge its  responsibilities  under the Depository Agreement with respect
to the  Certificates and the Trust  Administrator  or the Depositor is unable to locate a qualified  successor,
(b) the  Depositor,  with the  consent of the  applicable  Participants,  advises  the Trust  Administrator  in
writing that it elects to terminate the book-entry system with respect to the Book-Entry  Certificates  through
the Clearing  Agency or (c) after  the  occurrence of an Event of Default,  Holders of Book-Entry  Certificates
evidencing  not less than 66-2/3% of the  aggregate  Class  Principal  Balance of the  Book-Entry  Certificates
advise the Trust  Administrator  in writing that the  continuation  of a book-entry  system with respect to the
such  Certificates  through  the  Clearing  Agency is no longer in the best  interests  of the  Holders of such
Certificates with respect to the Book-Entry  Certificates and the applicable  Participants  consent,  the Trust
Administrator  shall  notify  all  Holders of such  Certificates  of the  occurrence  of any such event and the
availability of Definitive  Certificates.  Upon surrender to the Trust  Administrator  of such  Certificates by
the Clearing Agency,  accompanied by registration  instructions from the Clearing Agency for registration,  the
Trust  Administrator  shall  authenticate  and deliver the Definitive  Certificates.  Neither the Depositor nor
the Trust  Administrator  shall be liable for any delay in delivery of such  instructions  and may conclusively
rely  on,  and  shall  be  protected  in  relying  on,  such  instructions.  Upon the  issuance  of  Definitive
Certificates  all  references  herein to  obligations  imposed upon or to be  performed by the Clearing  Agency
shall be deemed to be imposed upon and  performed by the Trust  Administrator,  to the extent  applicable  with
respect  to such  Definitive  Certificates,  and  the  Trust  Administrator  shall  recognize  the  Holders  of
Definitive Certificates as Certificateholders hereunder.

obligations specifically and respectively imposed upon and undertaken by them herein.

SECTION 7.02.  Merger or Consolidation of the Seller, the Depositor, the Back-Up Servicer, the Master
                                    Servicer, the Servicers or the Special Servicer.

               Subject  to the  immediately  succeeding  paragraph,  the  Depositor,  the  Seller,  the  Master
Servicer,  the Back-Up  Servicer,  each Servicer and the Special  Servicer will each do or cause to be done all
things  necessary to preserve and keep in full force and effect its existence,  rights and franchises  (charter
and statutory) and will each obtain and preserve its  qualification to do business as a foreign  corporation in
each  jurisdiction  in  which  such  qualification  is or  shall be  necessary  to  protect  the  validity  and
enforceability  of this  Agreement,  or any of the Mortgage  Loans and to perform its  respective  duties under
this Agreement.

               Any Person into which the Depositor,  the Seller, the Master Servicer, the Back-Up Servicer, any
Servicer or the Special  Servicer may be merged or  consolidated,  or any Person  resulting  from any merger or
consolidation to which the Depositor,  the Seller, the Master Servicer,  the Back-Up Servicer,  any Servicer or

the Back-Up  Servicer  or any  Servicer,  shall be the  successor  of the  Depositor,  the Seller,  the Back-Up
Servicer or such Servicer,  as the case may be, hereunder,  without the execution or filing of any paper or any
further  act on the  part of any of the  parties  hereto,  anything  herein  to the  contrary  notwithstanding;
provided,  however,  that the successor or surviving Person to the Master Servicer,  the Back-Up Servicer,  any
such Servicer or the Special  Servicer  shall be qualified to sell mortgage  loans to, and to service  mortgage
loans on behalf of, FNMA or FHLMC.

               Notwithstanding  anything else in this  Section 7.02 or in Section 7.04  hereof to the contrary,
the Master  Servicer or a Servicer  may assign its rights and delegate  its duties and  obligations  under this
Agreement;  provided,  however, that the Master Servicer or such Servicer gives the Depositor,  the Trustee and
the Trust Administrator  notice of such assignment;  provided,  further,  (a) that such purchaser or transferee
accepting  such  assignment  and  delegation  shall  be an  institution  that  is a  FNMA  and  FHLMC  approved
seller/servicer  in good  standing,  which has a net worth of at least  $15,000,000,  and which is  willing  to

Trustee and the Trust  Administrator an agreement  accepting such delegation and assignment,  which contains an
assumption by such Person of the rights, powers, duties,  responsibilities,  obligations and liabilities of the
Master Servicer,  the Back-Up Servicer or such Servicer,  with like effect as if originally named as a party to
this  Agreement;  provided,  further,  that each of the  Rating  Agencies  acknowledge  that its  rating of the
Certificates  in effect  immediately  prior to such  assignment will not be qualified or reduced as a result of
such assignment and delegation.  In the case of any such assignment and delegation,  the Master  Servicer,  the
Back-Up  Servicer or such  Servicer  shall be released from its  obligations  under this  Agreement  (except as
provided  above),  except that the Master  Servicer,  Back-Up  0Servicer or the related  Servicer  shall remain
liable  for all  liabilities  and  obligations  incurred  by it as the Master  Servicer,  Back-Up  Servicer  or

               None of the Depositor,  the Master Servicer, the Back-Up Servicer, any Servicer, the Seller, the
Special  Servicer,  nor any of the  directors,  officers,  employees  or agents of the  Depositor,  the  Master
Servicer,  the Back-Up Servicer,  any Servicer, the Seller or the Special Servicer shall be under any liability
to the  Certificateholders  for any action taken or for refraining  from the taking of any action in good faith
pursuant to this  Agreement,  or for errors in  judgment;  provided,  however,  that this  provision  shall not
protect the Depositor,  the Master  Servicer,  the Back-Up  Servicer,  any Servicer,  the Seller or the Special
Servicer against any breach of  representations  or warranties made by it herein or protect the Depositor,  the
Master Servicer,  the Back-Up Servicer,  any Servicer, the Seller or the Special Servicer or any such director,
officer,  employee  or agent  from any  liability  which  would  otherwise  be  imposed  by  reasons of willful

disregard  of  obligations  and duties  hereunder.  None of the  Depositor,  the Master  Servicer,  the Back-Up
Servicer,  any  Servicer,  the  Seller or the  Special  Servicer  shall be under any  obligation  to appear in,
prosecute or defend any legal action that is not incidental to their  respective  duties hereunder and which in
its opinion may involve it in any expense or  liability;  provided,  however,  that the  Depositor,  the Master
Servicer,  the Back-Up  Servicer,  any  Servicer,  the Seller or the  Special  Servicer  may in its  discretion
undertake any such action that it may deem  necessary or desirable in respect of this  Agreement and the rights
and  duties  of  the  parties  hereto  and  interests  of  the  Trustee,   the  Trust   Administrator  and  the

Servicer or the Special  Servicer has been advised of the  likelihood of such loss or damage and  regardless of
the form of action.

SECTION 7.04.  Master Servicer and Servicer Not to Resign; Transfer of Servicing.

(a)     Neither the Master  Servicer  nor any  Servicer  shall resign from the  obligations  and duties  hereby
imposed on it except (i) upon  appointment of a successor master servicer or successor  servicer and receipt by
the  Trustee and the Trust  Administrator  of a letter from each  Rating  Agency  that such a  resignation  and
appointment  will  not  result  in a  downgrading  of the  rating  of any of the  Certificates  related  to the
applicable  Mortgage  Loans, or (ii) upon  determination  that its duties  hereunder are no longer  permissible
under  applicable  law. Any such  determination  under clause  (ii) permitting  the  resignation  of the Master
Servicer or a Servicer  shall be  evidenced  by an Opinion of Counsel to such effect  delivered  to the Trustee
and the Trust  Administrator.  No such  resignation  shall become effective until the successor master servicer
or  successor   servicer  shall  have  assumed  the  Master  Servicer  or  such   Servicer's,   as  applicable,
responsibilities, duties, liabilities and obligations hereunder in accordance with Section 8.02 hereof.

(b)     Notwithstanding the foregoing,  at DLJMC's request, so long as it is the owner of the related servicing
rights,  the Master  Servicer or SPS shall resign,  upon the selection and  appointment  of a successor  master
servicer or servicer,  as applicable;  provided that DLJMC delivers to the Trustee and the Trust  Administrator
the letter required in  Section 7.04(a)(i) above.  Notwithstanding the foregoing,  in the event that the Master
Servicer is appointed  as the  successor  servicer to SPS,  the  requirements  of  Section 7.04(a)(i) shall  be
waived.  In connection  with the foregoing,  unless  otherwise  directed by DLJMC in writing on or prior to the
first day of the second  month  following  the Closing  Date,  DLJMC  hereby  directs SPS to resign as Servicer
hereunder  and appoints the Master  Servicer to service the SPS Serviced  Mortgage  Loans,  effective as of the
first day of the third month  following  the Closing  Date.  In  connection  with its  resignation,  SPS hereby
agrees to deliver to the Master  Servicer on the date of its  resignation  a schedule  setting forth all of the
SPS Mortgage  Loans as of such date.  The Master  Servicer  agrees that, as of the first day of the third month
following  the  Closing  Date,  it will  service the SPS  Serviced  Mortgage  Loans,  and that such loans shall
constitute  Wells Fargo  Serviced  Mortgage  Loans,  in  accordance  with the terms of this  Agreement.  If the
Master Servicer resigns pursuant to this  Section 7.04(b),  DLJMC shall pay the Master Servicer an amount equal
to the  product  of (a) the  Stated  Principal  Balance  of all of the  Mortgage  Loans  then  outstanding  and
(b) 0.02%.

(c)     Notwithstanding  the  foregoing,  if the Trust  Administrator  shall for any  reason no longer be Trust
Administrator  hereunder,  at DLJMC's  request,  the Master  Servicer  shall  resign,  upon the  selection  and
appointment  of a  successor  master  servicer;  provided  that DLJMC  delivers  to the  Trustee  and the Trust
Administrator the letter required in Section 7.04(a)(i) above.

(d)     Notwithstanding  the  foregoing,  at DLJMC's  request,  the Special  Servicer  shall  resign,  upon the
selection  and  appointment  of a successor  special  servicer by DLJMC;  provided  that DLJMC  delivers to the
Trustee and the Trust Administrator the letter required in Section 7.04(a)(i) above.

SECTION 7.05.  Master Servicer, Seller and Servicers May Own Certificates.

               Each of the  Master  Servicer,  the  Seller,  the  Special  Servicer  and each  Servicer  in its
individual  or any other  capacity may become the owner or pledgee of  Certificates  with the same rights as it
would have if it were not the Master Servicer, the Seller, the Special Servicer or a Servicer.

SECTION 7.06.  Termination of Duties of the Back-Up Servicer.

               The rights and  obligations of the Back-Up  Servicer under this Agreement  shall  terminate upon
the earlier of (i) the  appointment  of the Back-Up  Servicer (or its  affiliate) as successor  Servicer to SPS
and (ii) the  termination of Wells Fargo as Back-Up  Servicer by the Seller.  The Seller may remove Wells Fargo
as Back-Up Servicer at any time.

SECTION 8.01.  Events of Default.

               "Event of Default," wherever used herein,  and as to the Master Servicer or any Servicer,  means
any one of the following  events  (whatever  reason for such Event of Default and whether it shall be voluntary
or  involuntary  or be effected by operation of law or pursuant to any  judgment,  decree or order of any court
or any order, rule or regulation of any administrative or governmental body):

(a)     any failure by the Master  Servicer or a Servicer  to remit to the  Certificateholders  or to the Trust
Administrator  any payment  other than an Advance  required to be made by the Master  Servicer or such Servicer
under the terms of this  Agreement,  which failure shall continue  unremedied for a period of (i) with  respect
to the Master  Servicer or a Servicer other than Wells Fargo,  one Business Day and (ii) with  respect to Wells
Fargo,  two Business  Days,  after the date upon which written  notice of such failure shall have been given to
the Master Servicer or such Servicer by the Trust  Administrator  or the Depositor or to the Master Servicer or
the related  Servicer and the Trust  Administrator  by the Holders of Certificates  having not less than 25% of
the Voting Rights evidenced by the Certificates; or

(b)     any  failure by the Master  Servicer or a Servicer  to observe or perform in any  material  respect any
other of the  covenants  or  agreements  on the part of the Master  Servicer  or a Servicer  contained  in this
Agreement  (except as set forth in (c) and  (g) below) which failure  (i) materially  affects the rights of the
Certificateholders  and (ii) shall  continue unremedied for a period of 60 days after the date on which written
notice  of such  failure  shall  have  been  given  to the  Master  Servicer  or  such  Servicer  by the  Trust
Administrator  or the Depositor,  or to the Master  Servicer or a Servicer and the Trust  Administrator  by the
Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates; or

(c)     if a  representation  or warranty set forth in  Section 2.03  hereof made solely in its capacity as the
Master  Servicer or a Servicer  shall prove to be materially  incorrect as of the time made in any respect that
materially and adversely  affects  interests of the  Certificateholders,  and the circumstances or condition in
respect of which such  representation  or warranty was incorrect shall not have been eliminated or cured within

(k)     (a) either (i) the master  servicer  rankings or ratings for the Master  Servicer are downgraded two or
more levels  below the level in effect on the  Closing  date by one or more of the Rating  Agencies  rating the
Certificates  or (ii) the  Master  Servicer  rankings or ratings for the Master  Servicer,  are  downgraded  to

failure,  requiring the same to be remedied,  shall have been given to the Servicer by the Trust Administrator,
the Master Servicer, the Trustee or the Depositor.

               If an Event of Default  due to the  actions or  inaction  of the Master  Servicer  or a Servicer
described in clauses  (a) through  (f) of this  Section shall  occur, then, and in each and every such case, so
long as such  Event  of  Default  shall  not have  been  remedied,  (i) the  Trust  Administrator  shall at the
direction  of the  Trustee or the Holders of  Certificates  evidencing  not less than 25% of the Voting  Rights
evidenced by the  Certificates,  by notice in writing to the Master  Servicer or such Servicer  (with a copy to
the Rating  Agencies),  terminate  all of the rights and  obligations  of the Master  Servicer or such Servicer
under this Agreement (other than rights to reimbursement for Advances and Servicing  Advances  previously made,
as provided in  Section 3.08)  and (ii) the Master Servicer may, if such Event of Default is due to the actions
or  inactions  of a  Servicer,  by notice in writing  to such  Servicer  (with a copy to the Rating  Agencies),
terminate  all of the rights and  obligations  of such  Servicer  under this  Agreement  (other  than rights to
reimbursement for Advances and Servicing Advances previously made, as provided in Section 3.08).

               If an Event of Default  described  in clause  (g) shall  occur,  (i) if the Master  Servicer has
failed to make any Advance,  the Trustee,  and (ii) if any Servicer has failed to make any Advance,  the Master
Servicer,  shall prior to the next  Distribution  Date,  immediately make such Advance and terminate the rights
and  obligations of the Master  Servicer or applicable  Servicer,  as applicable,  hereunder and succeed to the
rights  and  obligations  of the Master  Servicer  or such  Servicer,  as  applicable,  hereunder  pursuant  to
Section 8.02,  including the obligation to make Advances on such succeeding  Distribution  Date pursuant to the
terms  hereof.  No Event of Default with respect to the Master  Servicer or a Servicer  shall affect the rights
or duties of any other Servicer or constitute an Event of Default as to any other Servicer.

               If an Event of Default set forth in clause  (h)(ii) above  shall occur, the Trust  Administrator
shall furnish the  Certificateholders  the Master Servicer's  written report as to SPS's servicing  performance
in the next monthly  statement  to  Certificateholders  distributed  pursuant to  Section 4.05.  If an Event of
Default  set  forth in  clause  (h) or  (i) shall  occur,  the  Trust  Administrator  or the  Depositor  (after
consulting with the Trust Administrator),  may, or at the direction of  Certificateholders  evidencing not less
than 51% or more of the  Voting  Rights  evidenced  by the  Certificates,  the Trust  Administrator  shall,  by
written  notice  to the  Servicer  (with  a copy  to each  Rating  Agency),  terminate  all of the  rights  and
obligations  of SPS as  Servicer  under  this  Agreement.  With  respect  to an Event of  Default  set forth in
clauses (h) or  (i) above and upon any  termination of SPS as Servicer  pursuant to this  paragraph,  DLJMC, in
accordance with Section 7.04(b),  shall appoint a successor servicer,  irrespective of DLJMC's ownership of the
related  servicing rights.  Any such servicing  transfer as a result of an Event of Default set forth in clause
(h) or  (i) shall  be  accomplished  in 60 days  from the date the  Trust  Administrator  delivers  the  Master
Servicer's report to Certificateholders or from the date SPS received such notice of termination.

               If an Event of Default  described in clause (h) or (i)(3) occurs,  DLJMC shall reimburse SPS for
all  unreimbursed  Advances and Servicing  Advances made by SPS on the date the servicing is transferred to the
successor  servicer  hereunder and DLJMC shall be entitled to  reimbursement  by the successor  servicer of any
such amounts as and to the extent such amounts are received by the successor  servicer  under the terms of this
Agreement.

               If an Event of Default  described in clause (i), (j) or (l) occurs,  the Master  Servicer or the
Back-Up  Servicer  solely with respect to clause (i), shall at the direction of DLJMC,  by notice in writing to
such Servicer,  terminate all of the rights and  obligations of such Servicer under this Agreement  (other than
rights to reimbursement for Advances and Servicing  Advances  previously made, as provided in Section 3.08) and
shall appoint as successor  Servicer the entity  selected by DLJMC in accordance  with  Section 8.02;  provided
that DLJMC shall first furnish to the Master  Servicer or the Back-Up  Servicer,  as applicable,  a letter from
each Rating Agency that the  appointment  of such  successor  will not result in a downgrading of the rating of
any of the Certificates.

               If an Event of Default  described in clause (k) occurs,  the Trustee  shall at the  direction of
DLJMC, by notice in writing to the Master  Servicer,  terminate all of the rights and obligations of the Master
Servicer under this Agreement  (other than rights to  reimbursement  for Advances  previously made, as provided
in  Section 3.08)  and shall appoint as successor  Master  Servicer the entity  selected by DLJMC in accordance
with  Section 8.02;  provided  that DLJMC shall first  furnish to the Trustee a letter from each Rating  Agency
that  the  appointment  of such  successor  will  not  result  in a  downgrading  of the  rating  of any of the
Certificates.

               No Event of  Default  with  respect  to the  Servicer  shall  affect the rights or duties of the
Master Servicer or constitute an Event of Default as to the Master Servicer.

SECTION 8.02.  Master Servicer or Trust Administrator to Act; Appointment of Successor.

               On and after  the time the  Master  Servicer  or a  Servicer  receives  a notice of  termination
pursuant to  Section 8.01  hereof or resigns  pursuant to  Section 7.04  hereof,  subject to the  provisions of
Section 3.04  hereof, the Trustee (in the case of the Master Servicer),  the Trust Administrator or the Back-Up
Servicer  (in the  case of SPS),  shall  be the  successor  in all  respects  to the  Master  Servicer  or such
Servicer,  as  applicable,  in  its  capacity  as  servicer  under  this  Agreement  and  with  respect  to the
transactions  set forth or  provided  for herein and shall be subject to all the  responsibilities,  duties and
liabilities  relating thereto placed on the Master Servicer or such Servicer,  as applicable,  by the terms and
provisions hereof;  provided,  that the Trustee,  the Trust  Administrator,  the Master Servicer or the Back-Up
Servicer,  as applicable,  shall not be deemed to have made any  representation  or warranty as to any Mortgage
Loan made by the Master  Servicer or any  Servicer,  as  applicable,  and shall not effect any  repurchases  or
substitutions of any Mortgage Loan;  provided,  further,  that it is understood and acknowledged by the parties
hereto  that there will be a full  period of  transition  (not to exceed  ninety  (90) days)  before the actual
servicing  functions of any Servicer can be fully transferred to Wells Fargo as successor  Servicer;  provided,
further,  that during such period of transition Wells Fargo, as successor Servicer,  shall continue to make all
required  Compensating  Interest  Payments and  Advances.  As  compensation  therefor,  the Trustee,  the Trust
Administrator,  the Back-Up  Servicer or the Master  Servicer,  as  applicable,  shall be entitled to all funds
relating to the Mortgage Loans that the Master  Servicer or related  Servicer (the "Replaced  Servicer")  would
have been entitled to charge to the related  Collection  Account if the Replaced  Servicer had continued to act
hereunder (except that the Replaced  Servicer shall retain the right to be reimbursed for advances  (including,
without  limitation,  Advances and Servicing  Advances)  theretofore made by the Replaced Servicer with respect
to which it would be entitled to be  reimbursed  as provided in  Section 3.08  if it had not been so terminated
or resigned).  Notwithstanding the foregoing,  if the Trustee,  the Trust  Administrator,  the Back-Up Servicer
or the Master  Servicer,  as applicable,  has become the successor to a Replaced  Servicer,  in accordance with
this  Section 8.02,  the Trustee,  the Trust  Administrator,  the Back-Up Servicer or the Master  Servicer,  as
applicable,  may,  if it shall be  unwilling  to so act,  or  shall,  if it is unable  to so act,  appoint,  or
petition a court of competent  jurisdiction to appoint,  any established  mortgage loan servicing  institution,
the  appointment  of which  does not  adversely  affect the then  current  rating of the  Certificates,  as the
successor  to the Master  Servicer,  the Back-Up  Servicer  or a  Servicer,  as  applicable,  hereunder  in the
assumption  of all or any part of the  responsibilities,  duties or  liabilities  of the Master  Servicer,  the
Back-Up  Servicer or such Servicer,  as applicable,  provided that such successor to the Master  Servicer,  the
Back-Up  Servicer  or the  Servicer,  as  applicable,  shall not be deemed to have made any  representation  or
warranty as to any Mortgage Loan made by the Master Servicer or the related  Servicer,  as applicable.  Pending
appointment  of a successor  to the Master  Servicer,  the  Back-Up  Servicer  or a  Servicer,  as  applicable,
hereunder,  the Trustee,  the Trust Administrator or the Master Servicer,  as applicable,  unless such party is
prohibited  by law from so acting,  shall act in such  capacity as provided  herein.  In  connection  with such
appointment  and  assumption,  the  Trustee,  the Trust  Administrator,  the  Master  Servicer  or the  Back-Up
Servicer,  as applicable,  may make such arrangements for the compensation of such successor out of payments on
Mortgage Loans as it and such successor shall agree;  provided,  however, that no such compensation shall be in
excess of that  permitted  the Replaced  Servicer,  hereunder.  The  Trustee,  the Trust  Administrator  or the
Master Servicer, as applicable,  and such successor shall take such action,  consistent with this Agreement, as
shall be  necessary to  effectuate  any such  succession.  None of the Trustee,  the Trust  Administrator,  the
Master  Servicer nor any other successor  servicer shall be deemed to be in default  hereunder by reason of any
failure to make,  or any delay in making,  any  distribution  hereunder  or any portion  thereof  caused by the
failure of a Replaced Servicer to deliver, or any delay in delivering, cash, documents or records to it.

               A Replaced  Servicer that has been terminated  shall,  at the request of the Trustee,  the Trust
Administrator,  the  Master  Servicer  or the  Back-Up  Servicer,  as  applicable,  but at the  expense of such
Replaced  Servicer deliver to the assuming party all documents and records relating to the applicable  Mortgage
Loans and an accounting of amounts collected and held by it and otherwise use commercially  reasonable  efforts
to effect the orderly and efficient  transfer and assignment of such  servicing,  but only to the extent of the
Mortgage  Loans  serviced  thereunder,  to  the  assuming  party.  Notwithstanding  anything  to  the  contrary
contained  herein,  the  termination  of a Servicer under this  Agreement  shall not extend to any  Subservicer
meeting the requirements of  Section 3.02(a) and  otherwise  servicing the related Mortgage Loans in accordance
with the servicing provisions of this Agreement.

               The Master  Servicer,  the Back-Up  Servicer and each Servicer shall  cooperate with the Trustee
and the Trust  Administrator and any successor  servicer in effecting the termination of a Replaced  Servicer's
responsibilities  and rights  hereunder,  including  without  limitation,  the transfer to such  successor  for
administration  by it of all  cash  amounts  which  shall  at the  time be  credited  by such  Servicer  to the
applicable Collection Account or thereafter received with respect to the Mortgage Loans.

               None of the Trustee,  the Trust  Administrator nor any other successor  servicer shall be deemed
to be in  default  hereunder  by reason  of any  failure  to make,  or any delay in  making,  any  distribution
hereunder or any portion  thereof caused by (a) the  failure of the Master  Servicer,  the Back-Up  Servicer or
any Servicer to (i) deliver,  or any delay in delivering,  cash,  documents or records to it, or (ii) cooperate
as required by this Agreement,  or  (b) restrictions  imposed by any regulatory  authority having  jurisdiction
over the Master Servicer, the Back-Up Servicer or the related Servicer.

               Any  successor  to a Servicer  as  servicer  shall  during the term of its  service as  servicer
maintain  in  force  the  policy  or  policies  that  such  Servicer  is  required  to  maintain   pursuant  to
Section 3.09(b) hereof.

               If a Servicer  that has been  terminated  fails to pay all costs  related to the  transition  of
servicing to the  successor  Servicer,  the  successor  Servicer  shall be entitled to  reimbursement  of those
amounts from the Trust.

               In connection  with the  termination  or  resignation  of a Servicer  hereunder,  either (i) the
successor  Servicer,  including the Trust  Administrator or Master Servicer if either of such parties is acting
as successor  Servicer or Back-Up Servicer,  shall represent and warrant that it or an affiliate is a member of
MERS in good  standing  and shall agree to comply in all material  respects  with the rules and  procedures  of
MERS in  connection  with the  servicing  of the  related  Mortgage  Loans that are  registered  with MERS,  or
(ii) the  Replaced  Servicer,  at its sole expense,  shall cooperate with the successor  Servicer either (x) in
causing  MERS to execute and deliver an  Assignment  of Mortgage in  recordable  form to transfer  the Mortgage
from MERS to the Trustee and to execute and deliver such other  notices,  documents  and other  instruments  as
may be necessary or desirable to effect a transfer of such  Mortgage  Loan or servicing of such  Mortgage  Loan
on the MERS®  System to the  successor  Servicer or (y) in  causing  MERS to  designate on the MERS® System the
successor  Servicer as the servicer of such Mortgage  Loan (at the cost and expense of the  successor  Servicer
to the  extent  such  costs  relate  to the  qualification  of such  successor  Servicer  as a member  of MERS,
otherwise at the cost and expense of the Replaced  Servicer).  The Replaced  Servicer shall file or cause to be
filed any such  assignment  in the  appropriate  recording  office.  The  successor  Servicer  shall cause such
assignment  to be delivered to the Trustee  promptly  upon receipt of the original  with  evidence of recording
thereon or a copy certified by the public recording office in which such assignment was recorded.

SECTION 8.03.  Notification to Certificateholders.

(a)     Upon any  termination or appointment of a successor to the Master  Servicer or any Servicer,  the Trust
Administrator  shall give  prompt  written  notice  thereof to the Seller and the  Certificateholders  at their
respective addresses appearing in the Certificate Register and to the Rating Agencies,  or, as applicable,  the
Master Servicer shall give prompt written notice thereof to the Trust Administrator.

(b)     Within two Business Days after the occurrence of any Event of Default,  the Trust  Administrator  shall
transmit by mail to the Seller and all  Certificateholders,  and the Rating  Agencies notice of each such Event
of Default  hereunder known to the Trust  Administrator,  unless such Event of Default shall have been cured or
waived.

SECTION 8.04.  Waiver of Events of Default.

               The  Holders  representing  at least 66% of the  Voting  Rights of  Certificates  affected  by a
default or Event of Default  hereunder  may waive any  default or Event of  Default;  provided,  however,  that
(a) a default or Event of Default under clause (g) of  Section 8.01  may be waived,  only by all of the Holders
of Certificates  affected by such default or Event of Default and (b) no waiver  pursuant to this  Section 8.04
shall affect the Holders of Certificates in the manner set forth in  Section 12.01(b)(i),  (ii) or (iii).  Upon
any such  waiver of a default or Event of Default by the  Holders  representing  the  requisite  percentage  of
Voting Rights of  Certificates  affected by such default or Event of Default,  such default or Event of Default
shall  cease to exist and shall be deemed to have been  cured and  remedied  for every  purpose  hereunder.  No
such  waiver  shall  extend  to any  subsequent  or other  default  or Event of  Default  or  impair  any right
consequent thereon except to the extent expressly so waived.

                                                   ARTICLE IX

                                            CONCERNING THE TRUSTEE

SECTION 9.01.  Duties of Trustee.

               The Trustee,  prior to the  occurrence  of an Event of Default and after the curing or waiver of
all  Events of Default  that may have  occurred,  undertakes  with  respect  to the Trust Fund to perform  such
duties and only such duties as are  specifically  set forth in this  Agreement.  In case an Event of Default of
which a Responsible  Officer of the Trustee shall have actual knowledge has occurred and remains  uncured,  the
Trustee shall  exercise such of the rights and powers vested in it by this  Agreement,  and use the same degree
of care and skill in their exercise,  as a prudent person would exercise or use under the  circumstances in the
conduct of such person's own affairs.  Any permissive  right of the Trustee set forth in this  Agreement  shall
not be construed as a duty.

               The Trustee,  upon receipt of all  resolutions,  certificates,  statements,  opinions,  reports,
documents,  orders  or other  instruments  furnished  to the  Trustee  that  are  specifically  required  to be
furnished  pursuant to any provision of this Agreement shall examine them to determine  whether they conform to
the  requirements  of this  Agreement.  The Trustee shall have no duty to recompute,  recalculate or verify the
accuracy of any resolution,  certificate,  statement,  opinion,  report, document, order or other instrument so
furnished  to the  Trustee.  If any such  instrument  is found not to  conform in any  material  respect to the
requirements  of this  Agreement,  the Trustee shall notify the  Certificateholders  of such  instrument in the
event that the Trustee, after so requesting, does not receive a satisfactorily corrected instrument.

               No provision of this Agreement  shall be construed to relieve the Trustee from liability for its
own  negligent  action,  its own  negligent  failure to act or its own  misconduct,  its  negligent  failure to
perform its obligations in compliance  with this  Agreement,  or any liability which would be imposed by reason
of its willful misfeasance or bad faith; provided, however, that:

(a)     prior to the  occurrence  of an Event of Default of which a  Responsible  Officer of the Trustee  shall
have  actual  knowledge,  and after the curing or of all such  Events of Default  that may have  occurred,  the
duties and obligations of the Trustee shall be determined  solely by the express  provisions of this Agreement,
the Trustee shall not be personally  liable except for the  performance  of such duties and  obligations as are
specifically  set  forth in this  Agreement,  no  implied  covenants  or  obligations  shall be read  into this
Agreement  against the Trustee and the Trustee may  conclusively  rely, as to the truth of the  statements  and
the correctness of the opinions expressed  therein,  upon any certificates or opinions furnished to the Trustee
and conforming to the  requirements of this Agreement which it reasonably  believed in good faith to be genuine
and to have been duly executed by the proper authorities respecting any matters arising hereunder;

(b)     the  Trustee  shall  not be  personally  liable  for an  error  of  judgment  made in good  faith  by a
Responsible  Officer or Responsible  Officers of the Trustee,  unless the Trustee was negligent in ascertaining
or investigating the pertinent facts;

(c)     the Trustee shall not be personally liable with respect to any action taken,  suffered or omitted to be
taken by it in good faith in accordance  with this  Agreement at the  direction of the Holders of  Certificates
evidencing  greater than 50% of the Voting  Rights  allocated  to each  Class of  Certificates  relating to the
time,  method and place of conducting  any proceeding  for any remedy  available to the Trustee,  or exercising
any trust or power conferred upon the Trustee, under this Agreement;

(d)     no provision of this  Agreement  shall require the Trustee to expend or risk its own funds or otherwise
incur any financial  liability in the  performance of any of its duties  hereunder or in the exercise of any of
its  rights or powers if it shall  have  reasonable  grounds  for  believing  that  repayment  of such funds or
adequate indemnity against such risk or liability is not reasonably assured to it; and

(e)     the  Trustee  shall  have no  responsibility  for any act or  omission  of the Trust  Administrator  or
LaSalle,  it being  understood and agreed that the Trustee,  Trust  Administrator  and LaSalle are  independent
contractors and not agents, partners or joint venturers.

               The Trustee shall not be deemed to have  knowledge of any Event of Default or event which,  with
notice or lapse of time,  or both,  would  become an Event of  Default,  unless a  Responsible  Officer  of the
Trustee shall have received written notice thereof from a Servicer,  the Depositor or a  Certificateholder,  or
a  Responsible  Officer of the  Trustee  has  actual  notice  thereof,  and in the  absence  of such  notice no
provision  hereof requiring the taking of any action or the assumption of any duties or  responsibility  by the
Trustee  following  the  occurrence  of any Event of Default or event  which,  with  notice or lapse of time or
both, would become an Event of Default, shall be effective as to the Trustee.

               The Trustee shall have no duty hereunder with respect to any complaint,  claim,  demand,  notice
or other  document  it may receive or which may be alleged to have been  delivered  to or served upon it by the
parties as a  consequence  of the  assignment  of any Mortgage  Loan  hereunder;  provided,  however,  that the
Trustee  shall use its best  efforts to remit to the Master  Servicer or the related  Servicer  upon receipt of
any such  complaint,  claim,  demand,  notice or other document  (i) which is delivered to the Corporate  Trust
Office of the Trustee,  (ii) of which a Responsible  Officer has actual  knowledge,  and  (iii) which  contains
information  sufficient  to permit the  Trustee to make a  determination  that the real  property to which such
document relates is a Mortgaged Property.

SECTION 9.02.  Certain Matters Affecting the Trustee.

(a)     Except as otherwise provided in Section 9.01:

(i)     the Trustee may request and rely upon and shall be protected in acting or  refraining  from acting upon
        any  resolution,  Officer's  Certificate,  certificate  of  auditors,  Servicing  Officers or any other
        certificate,  statement,  instrument, opinion, report, notice, request, consent, order, appraisal, bond
        or other paper or document  believed  by it to be genuine and to have been signed or  presented  by the
        proper party or parties;

(ii)    the Trustee may consult with counsel,  financial advisors or accountants and any advice of such Persons
        or any Opinion of Counsel  shall be full and complete  authorization  and  protection in respect of any
        action taken or suffered or omitted by it hereunder  in good faith and in  accordance  with such advice
        or Opinion of Counsel;

(iii)   the Trustee  shall be under no  obligation to exercise any of the trusts or powers vested in it by this
        Agreement or to  institute,  conduct or defend any  litigation  hereunder or in relation  hereto at the
        request,  order or  direction  of any of the  Certificateholders  pursuant  to the  provisions  of this
        Agreement,  unless such  Certificateholders  shall have offered to the Trustee  reasonable  security or
        indemnity  against  the costs,  expenses  and  liabilities  which may be  incurred  therein or thereby;
        nothing contained herein shall, however, relieve the Trustee of the obligation,  upon the occurrence of
        an Event of Default of which a Responsible  Officer of the Trustee shall have actual  knowledge  (which
        has not been  cured or  waived),  to  exercise  such of the  rights  and  powers  vested  in it by this
        Agreement,  and to use the same degree of care and skill in their  exercise as a prudent  person  would
        exercise or use under the circumstances in the conduct of such person's own affairs;

(iv)    the Trustee  shall not be  personally  liable for any action  taken,  suffered or omitted by it in good
        faith and believed by it to be authorized or within the  discretion or rights or powers  conferred upon
        it by this Agreement;

(v)     prior to the  occurrence of an Event of Default  hereunder and after the curing or waiver of all Events
        of Default that may have occurred,  the Trustee shall not be bound to make any  investigation  into the
        facts or  matters  stated in any  resolution,  certificate,  statement,  instrument,  opinion,  report,
        notice,  request,  consent,  order,  approval,  bond or other paper or  document,  unless  requested in
        writing so to do by Holders of Certificates  evidencing greater than 50% of the Voting Rights allocated
        to each Class of Certificates;  provided,  however, that if the payment within a reasonable time to the
        Trustee  of the  costs,  expenses  or  liabilities  likely to be  incurred  by it in the making of such
        investigation is, in the opinion of the Trustee,  not reasonably assured to the Trustee by the security
        afforded to it by the terms of this Agreement,  the Trustee may require  reasonable  indemnity  against
        such expense or liability as a condition  to taking any such action;  the  reasonable  expense of every
        such investigation  shall be paid (A) by the Master Servicer or by the applicable Servicer in the event
        that such  investigation  relates to an Event of Default by the Master  Servicer  or by such  Servicer,
        respectively,  if an Event of Default by the Master  Servicer or by such  Servicer  shall have occurred
        and is continuing, and (B) otherwise by the Certificateholders requesting the investigation;

(vi)    the Trustee may execute any of the trusts or powers  hereunder or perform any duties  hereunder  either
        directly  or by or  through  agents or  attorneys  and the  Trustee  shall not be  responsible  for any
        misconduct or negligence on the part of any such agent or attorney appointed with due care;

(vii)   the Trustee shall not be required to expend its own funds or otherwise  incur any  financial  liability
        in the  performance of any of its duties  hereunder if it shall have  reasonable  grounds for believing
        that repayment of such funds or adequate indemnity against such liability is not assured to it;

(viii)  the Trustee shall not be liable for any loss on any investment of funds pursuant to this Agreement; and

(ix)    the right of the Trustee to perform any  discretionary  act enumerated in this  Agreement  shall not be
        construed as a duty,  and the Trustee shall not be answerable  for other than its negligence or willful
        misconduct in the performance of such act.

(b)     All  rights  of action  under  this  Agreement  or under any of the  Certificates,  enforceable  by the
Trustee,  may be enforced by it without the possession of any of the  Certificates,  or the production  thereof
at the trial or other proceeding  relating thereto,  and any such suit, action or proceeding  instituted by the
Trustee  shall be brought in its name for the benefit of all the Holders of such  Certificates,  subject to the
provisions of this Agreement.

SECTION 9.03.  Trustee Not Liable for Certificates or Mortgage Loans.

               The recitals  contained  herein shall be taken as the  statements of the Depositor or the Master
Servicer or a Servicer,  as the case may be, and the Trustee assumes no responsibility  for their  correctness.
The Trustee makes no representations  as to the validity or sufficiency of this Agreement,  the Certificates or
of any  Mortgage  Loan  or  related  document  or of  MERS  or the  MERS®  System.  The  Trustee  shall  not be
accountable  for the use or application by the Depositor,  the Seller,  the Master Servicer or any Servicers of
any funds paid to the  Depositor or the Master  Servicer or any  Servicer in respect of the  Mortgage  Loans or
deposited in or withdrawn from the  Certificate  Account by the Depositor,  the Seller,  the Master Servicer or
the  Servicers.  The Trustee  shall not be  responsible  for the legality or validity of this  Agreement or the
validity,  priority,  perfection or sufficiency of the security for the  Certificates  issued or intended to be
issued  hereunder.  The  Trustee  shall  have no  responsibility  for  filing  any  financing  or  continuation
statement in any public office at any time or to otherwise  perfect or maintain the  perfection of any security
interest or lien granted to it hereunder or to record this Agreement.

SECTION 9.04.  Trustee May Own Certificates.

               The  Trustee  in its  individual  or any other  capacity  may  become  the owner or  pledgee  of
Certificates and may transact business with the other parties hereto and with their  Affiliates,  with the same
rights as it would have if it were not the Trustee.

SECTION 9.05.  Trustee's Fees and Expenses.

               The Trustee shall be compensated by the Trust  Administrator as separately  agreed.  The Trustee
and any director,  officer,  employee or agent of the Trustee shall be  indemnified  by DLJMC and held harmless
(up to a maximum of $150,000)  against any loss,  liability or expense  (including  reasonable  attorney's fees
and  expenses)  (i) incurred  in  connection  with any claim or legal  action  relating to (a) this  Agreement,
(b) the  Certificates,  or (c) the  performance of any of the Trustee's duties hereunder,  other than any loss,
liability or expense  incurred by reason of willful  misconduct,  bad faith or negligence in the performance of
any of the  Trustee's  duties  hereunder  or  incurred  by reason of any  action  of the  Trustee  taken at the
direction  of the  Certificateholders  and  (ii) resulting  from  any  error in any tax or  information  return
prepared  by the  Master  Servicer  or a  Servicer.  Such  indemnity  shall  survive  the  termination  of this
Agreement  or the  resignation  or removal of the  Trustee  hereunder.  Without  limiting  the  foregoing,  the
Depositor  covenants and agrees,  except as otherwise  agreed upon in writing by the Depositor and the Trustee,
and except for any such  expense,  disbursement  or advance  as may arise from the  Trustee's  negligence,  bad
faith or willful misconduct,  to pay or reimburse the Trustee, for all reasonable  expenses,  disbursements and
advances  incurred or made by the Trustee in  accordance  with any of the  provisions  of this  Agreement  with
respect to: (A) the reasonable  compensation  and the expenses and  disbursements of its counsel not associated
with  the  closing  of the  issuance  of the  Certificates,  (B)  the  reasonable  compensation,  expenses  and
disbursements of any accountant,  engineer or appraiser that is not regularly  employed by the Trustee,  to the
extent that the Trustee  must engage such persons to perform  acts or services  hereunder  and (C) printing and
engraving  expenses in connection  with preparing any  Definitive  Certificates.  Except as otherwise  provided
herein,  the Trustee  shall not be  entitled  to payment or  reimbursement  for any  routine  ongoing  expenses
incurred by the Trustee in the ordinary  course of its duties as Trustee  hereunder or for any other  expenses.
Anything  in this  Agreement  to the  contrary  notwithstanding,  in no event  shall the  Trustee be liable for
special,  indirect or  consequential  loss or damage of any kind whatsoever  (including but not limited to lost
profits),  even if the Trustee has been advised of the  likelihood of such loss or damage and regardless of the
form of action.

SECTION 9.06.  Eligibility Requirements for Trustee.

               The Trustee  hereunder  shall at all times be a corporation or  association  organized and doing
business  under the laws of any state or the United States of America,  authorized  under such laws to exercise
corporate  trust powers,  having ratings on its long term debt  obligations at the time of such  appointment in
at least the third  highest  rating  category by both Moody's and S&P  (provided  that if such rating is in the
third  highest  rating  category of S&P, the Trustee  shall also have a  short-term  rating from S&P of A-1) or
such  lower  ratings as will not cause  Moody's  or S&P to lower  their  then  current  ratings of the  Class A
Certificates  (other than the Class 5-X and Residual  Certificates),  having a combined  capital and surplus of
at least  $50,000,000  and  subject to  supervision  or  examination  by federal  or state  authority.  If such
corporation  or  association  publishes  reports of  condition  at least  annually,  pursuant  to law or to the
requirements of the aforesaid  supervising or examining  authority,  then for the purposes of this Section 9.06
the  combined  capital  and  surplus of such  corporation  or  association  shall be deemed to be its  combined
capital and surplus as set forth in its most  recent  report of  condition  so  published.  In case at any time
the Trustee shall cease to be eligible in accordance  with the  provisions  of this  Section 9.06,  the Trustee
shall resign immediately in the manner and with the effect specified in Section 9.07 hereof.

SECTION 9.07.  Resignation and Removal of Trustee.

               The  Trustee  may at any time  resign  and be  discharged  from the  trusts  hereby  created  by
(a) giving  written  notice of  resignation  to the  Depositor,  DLJMC,  the Trust  Administrator,  the  Master
Servicer,  the Special  Servicer and the Servicers and by mailing  notice of  resignation  by first class mail,
postage prepaid, to the  Certificateholders  at their addresses appearing on the Certificate  Register,  and to
the  Rating  Agencies,  not less than 60 days  before  the date  specified  in such  notice  when,  subject  to
Section 9.08,  such resignation is to take effect, and (b) acceptance by a successor trustee in accordance with
Section 9.08 meeting the qualifications set forth in Section 9.06.

               If at any time the  Trustee  shall cease to be eligible in  accordance  with the  provisions  of
Section 9.06  hereof and shall fail to resign after  written  request  thereto by the  Depositor,  or if at any
time the  Trustee  shall  become  incapable  of acting,  or shall be  adjudged a bankrupt  or  insolvent,  or a
receiver of the Trustee or of its  property  shall be  appointed,  or any public  officer  shall take charge or
control of the  Trustee or of its  property  or affairs  for the  purpose of  rehabilitation,  conservation  or
liquidation  or if  the  Trustee  breaches  any of its  obligations  or  representations  hereunder,  then  the
Depositor  may remove the Trustee and appoint a successor  trustee by written  instrument,  in  duplicate,  one
copy of  which  instrument  shall be  delivered  to the  Trustee  and one copy to the  successor  trustee.  The
Trustee  may also be removed at any time by the  Holders of  Certificates  evidencing  not less than 50% of the
Voting  Rights  evidenced  by the  Certificates.  Notice  of any  removal  of the  Trustee  and  acceptance  of
appointment by the successor trustee shall be given to the Rating Agencies by the Depositor.

               If no successor  trustee shall have been so appointed and have  accepted  appointment  within 30
days after the giving of such notice of  resignation or receipt of a notice of removal,  the resigning  Trustee
may, at the Trust Fund's  expense,  petition  any court of  competent  jurisdiction  for the  appointment  of a
successor trustee.

               Any  resignation or removal of the Trustee and  appointment of a successor  trustee  pursuant to
any of the  provisions of this  Section 9.07  shall become  effective  upon  acceptance of  appointment  by the
successor trustee as provided in Section 9.08 hereof.

SECTION 9.08.  Successor Trustee.

               Any successor  trustee appointed as provided in Section 9.07  hereof shall execute,  acknowledge
and  deliver  to the  Depositor  and to its  predecessor  trustee  an  instrument  accepting  such  appointment
hereunder and thereupon the resignation or removal of the predecessor  trustee shall become  effective and such
successor  trustee,  without any further  act,  deed or  conveyance,  shall  become  fully  vested with all the
rights,  powers,  duties and  obligations of its predecessor  hereunder,  with the like effect as if originally
named as trustee  herein.  The  Depositor,  upon receipt of all amounts due it hereunder,  and the  predecessor
trustee shall execute and deliver such  instruments  and do such other things as may reasonably be required for
more fully and certainly vesting and confirming in the successor trustee all such rights,  powers,  duties, and
obligations.

               No successor  trustee shall accept  appointment as provided in this  Section 9.08  unless at the
time of such  acceptance such successor  trustee shall be eligible under the provisions of Section 9.06  hereof
and its acceptance shall not adversely affect the then current rating of the Certificates.

               Upon  acceptance of appointment  by a successor  trustee as provided in this  Section 9.08,  the
Depositor  shall mail notice of the  succession  of such trustee  hereunder to all Holders of  Certificates  at
their  addresses as shown in the  Certificate  Register.  If the Depositor fails to mail such notice within ten
days after acceptance of appointment by the successor  trustee,  the successor  trustee shall cause such notice
to be mailed at the expense of the Depositor.

SECTION 9.09.  Merger or Consolidation of Trustee.

               Any  Person  into  which  the  Trustee  may be  merged  or  converted  or with  which  it may be
consolidated or any Person  resulting from any merger,  conversion or  consolidation to which the Trustee shall
be a party,  or any Person  succeeding  to the business of the Trustee,  shall be the  successor of the Trustee
hereunder,  provided that such Person shall be eligible  under the  provisions of  Section 9.06  hereof without
the execution or filing of any paper or further act on the part of any of the parties  hereto,  anything herein
to the contrary notwithstanding.

SECTION 9.10.  Appointment of Co-Trustee or Separate Trustee.

               Notwithstanding any other provisions of this Agreement,  at any time, for the purpose of meeting
any legal  requirements  of any  jurisdiction  in which any part of the Trust  Fund or  property  securing  any
Mortgage Note may at the time be located,  the Master  Servicer and the Trustee  acting  jointly shall have the
power and shall execute and deliver all  instruments to appoint one or more Persons  approved by the Trustee to
act as co-trustee or co-trustees  jointly with the Trustee,  or separate trustee or separate  trustees,  of all
or any part of the Trust Fund,  and to vest in such Person or Persons,  in such capacity and for the benefit of
the  applicable  Certificateholders,  such title to the Trust Fund,  or any part thereof,  and,  subject to the
other  provisions  of this  Section 9.10,  such powers,  duties,  obligations,  rights and trusts as the Master
Servicer and the Trustee may consider  necessary or  desirable.  If the Master  Servicer  shall not have joined
in such  appointment  within  fifteen  days  after the  receipt  by it of a request to do so, or in the case an
Event of Default  shall have  occurred and be  continuing,  the Trustee alone shall have the power to make such
appointment.  No co-trustee or separate  trustee  hereunder  shall be required to meet the terms of eligibility
as a successor  trustee  under  Section 9.06  and no notice to  Certificateholders  of the  appointment  of any
co-trustee or separate trustee shall be required under Section 9.08.

               Every separate  trustee and co-trustee  shall, to the extent  permitted by law, be appointed and
act subject to the following provisions and conditions:

(a)     all rights,  powers,  duties and  obligations  conferred or imposed  upon the  Trustee,  except for any
obligation  of the  Trustee  under this  Agreement  to  advance  funds on behalf of the  Master  Servicer  or a
Servicer,  shall be  conferred or imposed  upon and  exercised  or  performed by the Trustee and such  separate
trustee or co-trustee  jointly (it being  understood that such separate trustee or co-trustee is not authorized
to act  separately  without  the Trustee  joining in such act),  except to the extent that under any law of any
jurisdiction  in which any  particular  act or acts are to be  performed  by the  Trustee  (whether  as Trustee
hereunder  or as  successor  to the Master  Servicer  or a  Servicer),  the  Trustee  shall be  incompetent  or
unqualified  to  perform  such  act or acts,  in which  event  such  rights,  powers,  duties  and  obligations
(including  the holding of title to the Trust Fund or any portion  thereof in any such  jurisdiction)  shall be
exercised  and  performed  singly by such separate  trustee or  co-trustee,  but solely at the direction of the
Trustee;

(b)     no trustee  hereunder  shall be held  personally  liable by reason of any act or  omission of any other
trustee hereunder; and

(c)     the Master  Servicer and the Trustee acting jointly may at any time accept the resignation of or remove
any separate trustee or co-trustee.

               Any notice,  request or other writing given to the Trustee shall be deemed to have been given to
each of the then  separate  trustees  and  co-trustees,  as  effectively  as if  given  to each of them.  Every
instrument  appointing any separate  trustee or co-trustee  shall refer to this Agreement and the conditions of
this Article IX. Each separate trustee and co-trustee,  upon its acceptance of the trusts  conferred,  shall be
vested with the estates or property  specified  in its  instrument  of  appointment,  either  jointly  with the
Trustee  or  separately,  as may be  provided  therein,  subject  to all  the  provisions  of  this  Agreement,
specifically  including every provision of this Agreement  relating to the conduct of,  affecting the liability
of, or  affording  protection  to, the  Trustee.  Every such  instrument  shall be filed with the Trustee and a
copy thereof given to the Master Servicer or the Servicers and the Depositor.

               Any  separate  trustee or  co-trustee  may,  at any time,  constitute  the  Trustee its agent or
attorney-in-fact,  with full power and  authority,  to the extent not  prohibited  by law, to do any lawful act
under or in respect of this  Agreement  on its behalf  and in its name.  The Trust  Administrator  shall not be
responsible  for all action or inaction of any  separate  trustee or  co-trustee.  If any  separate  trustee or
co-trustee  shall die,  become  incapable  of acting,  resign or be removed,  all of its  estates,  properties,
rights,  remedies and trusts shall vest in and be  exercised  by the Trustee,  to the extent  permitted by law,
without the appointment of a new or successor trustee.

SECTION 9.11.  Office of the Trustee.

               The office of the Trustee for purposes of receipt of notices and demands is the Corporate  Trust
Office.

                                                    ARTICLE X

                                      CONCERNING THE TRUST ADMINISTRATOR

SECTION 10.01. Duties of Trust Administrator.

               The Trust  Administrator,  prior to the occurrence of an Event of Default of which a Responsible
Officer of the Trust  Administrator  shall have actual  knowledge  and after the curing or waiver of all Events
of Default that may have  occurred,  undertakes  with respect to the Trust Fund to perform such duties and only
such  duties  as are  specifically  set  forth  in this  Agreement.  In case an  Event  of  Default  of which a
Responsible  Officer of the Trust  Administrator  shall have actual knowledge has occurred and remains uncured,
the Trust  Administrator  shall exercise such of the rights and powers vested in it by this Agreement,  and use
the same  degree of care and skill in their  exercise,  as a prudent  person  would  exercise  or use under the
circumstances  in the conduct of such person's own affairs.  Any  permissive  right of the Trust  Administrator
set forth in this Agreement shall not be construed as a duty.

               The Trust Administrator,  upon receipt of all resolutions,  certificates,  statements, opinions,
reports,  documents,  orders or other instruments  furnished to the Trust  Administrator  that are specifically
required to be furnished  pursuant to any provision of this Agreement  shall examine them to determine  whether
they conform to the requirements of this Agreement.  The Trust  Administrator  shall have no duty to recompute,
recalculate  or verify the accuracy of any  resolution,  certificate,  statement,  opinion,  report,  document,
order or other  instrument  so furnished to the Trust  Administrator.  If any such  instrument  is found not to
conform in any material respect to the  requirements of this Agreement,  the Trust  Administrator  shall notify
the  Certificateholders  of such  instrument in the event that the Trust  Administrator,  after so  requesting,
does not receive a satisfactorily corrected instrument.

               No  provision of this  Agreement  shall be  construed  to relieve the Trust  Administrator  from
liability for its own negligent action,  its own negligent failure to act or its own misconduct,  its negligent
failure to perform its obligations in compliance  with this Agreement,  or any liability which would be imposed
by reason of its willful misfeasance or bad faith; provided, however, that:

(a)     prior  to the  occurrence  of an  Event  of  Default  of  which  a  Responsible  Officer  of the  Trust
Administrator  shall have  actual  knowledge,  and after the curing or of all such  Events of Default  that may
have  occurred,  the  duties and  obligations  of the Trust  Administrator  shall be  determined  solely by the
express  provisions of this Agreement,  the Trust  Administrator  shall not be personally liable except for the
performance  of such  duties  and  obligations  as are  specifically  set forth in this  Agreement,  no implied
covenants  or  obligations  shall be read into this  Agreement  against the Trust  Administrator  and the Trust
Administrator  may  conclusively  rely, as to the truth of the statements  and the  correctness of the opinions
expressed  therein,  upon any certificates or opinions  furnished to the Trust  Administrator and conforming to
the  requirements of this Agreement  which it reasonably  believed in good faith to be genuine and to have been
duly executed by the proper authorities respecting any matters arising hereunder;

(b)     the Trust  Administrator  shall not be personally liable for an error of judgment made in good faith by
a Responsible Officer or Responsible  Officers of the Trust  Administrator,  unless the Trust Administrator was
negligent in ascertaining or investigating the pertinent facts;

(c)     the Trust  Administrator  shall not be personally liable with respect to any action taken,  suffered or
omitted to be taken by it in good faith in  accordance  with this  Agreement or at the direction of the Holders
of  Certificates  evidencing  greater than 50% of the Voting  Rights  allocated to each  Class of  Certificates
relating to the time,  method and place of  conducting  any  proceeding  for any remedy  available to the Trust
Administrator,  or exercising any trust or power conferred upon the Trust Administrator,  under this Agreement;
and

(d)     no provision of this Agreement  shall require the Trust  Administrator  to expend or risk its own funds
or  otherwise  incur any  financial  liability  in the  performance  of any of its duties  hereunder  or in the
exercise of any of its rights or powers if it shall have  reasonable  grounds for believing  that  repayment of
such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

               The Trust Administrator shall have no duty (A) to see to any recording,  filing or depositing of
this  Agreement  or any  agreement  referred to herein or any  financing  statement or  continuation  statement
evidencing a security  interest,  or to see to the maintenance of any such  recording,  filing or depositing or
to any  rerecording,  refiling or  redepositing of any thereof,  (B) to see to any insurance,  or (C) to see to
the payment or discharge of any tax,  assessment or other  governmental  charge or any lien or  encumbrance  of
any kind owing with respect to,  assessed or levied  against,  any part of the Trust Fund other than from funds
available in the Certificate Account.

               Except with respect to an Event of Default  described in clause (a) of  Section 8.01,  the Trust
Administrator  shall not be deemed to have  knowledge  of any Event of Default or event  which,  with notice or
lapse  of time,  or both,  would  become  an Event of  Default,  unless  a  Responsible  Officer  of the  Trust
Administrator  shall  have  received  written  notice  thereof  from the Master  Servicer  or a  Servicer,  the
Depositor,  or a  Certificateholder,  or a  Responsible  Officer of the Trust  Administrator  has actual notice
thereof,  and in the  absence of such  notice no  provision  hereof  requiring  the taking of any action or the
assumption of any duties or  responsibility  by the Trust  Administrator  following the occurrence of any Event
of Default or event which,  with notice or lapse of time or both,  would  become an Event of Default,  shall be
effective as to the Trust Administrator.

               The Trust  Administrator  shall have no duty  hereunder  with respect to any  complaint,  claim,
demand,  notice or other  document it may receive or which may be alleged to have been  delivered  to or served
upon it by the parties as a consequence of the assignment of any Mortgage Loan  hereunder;  provided,  however,
that the Trust  Administrator  shall use its best efforts to remit to the Master  Servicer or the Servicer upon
receipt  of any such  complaint,  claim,  demand,  notice  or other  document  (i) which  is  delivered  to the
Corporate Trust Office of the Trust  Administrator,  (ii) of which a Responsible  Officer has actual knowledge,
and  (iii) which  contains  information  sufficient to permit the Trust  Administrator  to make a determination
that the real property to which such document relates is a Mortgaged Property.

SECTION 10.02. Certain Matters Affecting the Trust Administrator.

(a)     Except as otherwise provided in Section 10.01:

(i)     the Trust  Administrator  may request and rely upon and shall be protected in acting or refraining from
        acting upon any resolution,  Officer's Certificate,  certificate of auditors, Servicing Officers or any
        other certificate,  statement, instrument, opinion, report, notice, request, consent, order, appraisal,
        bond or other paper or document  believed by it to be genuine and to have been signed or  presented  by
        the proper party or parties;

(ii)    the Trust  Administrator may consult with counsel,  financial advisors or accountants and any advice of
        such Persons or opinion of counsel shall be full and complete  authorization  and protection in respect
        of any action taken or suffered or omitted by it hereunder  in good faith and in  accordance  with such
        advice or opinion of counsel;

(iii)   the Trust  Administrator shall be under no obligation to exercise any of the trusts or powers vested in
        it by this Agreement or to institute,  conduct or defend any litigation hereunder or in relation hereto
        at the request, order or direction of any of the Certificateholders  pursuant to the provisions of this
        Agreement,  unless such  Certificateholders  shall have offered to the Trust  Administrator  reasonable
        security or indemnity  against the costs,  expenses and  liabilities  which may be incurred  therein or
        thereby;  nothing contained herein shall,  however,  relieve the Trust Administrator of the obligation,
        upon the  occurrence of an Event of Default of which a Responsible  Officer of the Trust  Administrator
        shall have actual  knowledge  (which has not been cured or waived),  to exercise such of the rights and
        powers vested in it by this  Agreement,  and to use the same degree of care and skill in their exercise
        as a prudent person would exercise or use under the  circumstances  in the conduct of such person's own
        affairs;

(iv)    the Trust Administrator shall not be personally liable for any action taken,  suffered or omitted by it
        in good  faith and  believed  by it to be  authorized  or  within  the  discretion  or rights or powers
        conferred upon it by this Agreement;

(v)     prior to the  occurrence of an Event of Default  hereunder and after the curing or waiver of all Events
        of  Default  that  may  have  occurred,  the  Trust  Administrator  shall  not be  bound  to  make  any
        investigation into the facts or matters stated in any resolution,  certificate,  statement, instrument,
        opinion,  report, notice, request,  consent,  order, approval, bond or other paper or document,  unless
        requested  in writing so to do by Holders of  Certificates  evidencing  greater  than 50% of the Voting
        Rights  allocated  to each  Class of  Certificates;  provided,  however,  that if the payment  within a
        reasonable time to the Trust Administrator of the costs,  expenses or liabilities likely to be incurred
        by it in the  making  of  such  investigation  is,  in the  opinion  of the  Trust  Administrator,  not
        reasonably  assured to the Trust  Administrator  by the  security  afforded  to it by the terms of this
        Agreement,  the Trust Administrator may require reasonable  indemnity against such expense or liability
        as a condition to taking any such action; the reasonable  expense of every such investigation  shall be
        paid (A) by the Master  Servicer or by the  applicable  Servicer  in the event that such  investigation
        relates to an Event of Default by the Master  Servicer or by such Servicer,  respectively,  if an Event
        of Default by the Master  Servicer or such  Servicer  shall have  occurred and is  continuing,  and (B)
        otherwise by the Certificateholders requesting the investigation;

(vi)    the Trust  Administrator  may  execute  any of the trusts or powers  hereunder  or  perform  any duties
        hereunder  either directly or by or through agents or attorneys and the Trust  Administrator  shall not
        be  responsible  for any  misconduct or negligence on the part of any such agent or attorney  appointed
        with due care;

(vii)   the Trust  Administrator shall not be required to expend its own funds or otherwise incur any financial
        liability in the  performance of any of its duties  hereunder if it shall have  reasonable  grounds for
        believing that repayment of such funds or adequate  indemnity  against such liability is not assured to
        it;

(viii)  the Trust  Administrator  shall not be liable for any loss on any  investment of funds pursuant to this
        Agreement except as provided in Section 3.05(e);

(ix)    the right of the Trust  Administrator  to perform any  discretionary  act  enumerated in this Agreement
        shall not be construed as a duty,  and the Trust  Administrator  shall not be answerable for other than
        its negligence or willful misconduct in the performance of such act; and

(x)     The Trust  Administrator  shall not be required to give any bond or surety in respect of the  execution
        of the Trust Fund created hereby or the powers granted hereunder.

(b)     All rights of action under this  Agreement or under any of the  Certificates,  enforceable by the Trust
Administrator,  may be enforced by it without the  possession  of any of the  Certificates,  or the  production
thereof at the trial or other proceeding relating thereto,  and any such suit, action or proceeding  instituted
by the  Trust  Administrator  shall  be  brought  in its  name  for  the  benefit  of all the  Holders  of such
Certificates, subject to the provisions of this Agreement.

SECTION 10.03. Trust Administrator Not Liable for Certificates or Mortgage Loans.

               The recitals  contained  herein shall be taken as the  statements of the Depositor or the Master
Servicer or a Servicer,  as the case may be, and the Trust  Administrator  assumes no responsibility  for their
correctness.  The Trust  Administrator  makes no  representations  as to the  validity or  sufficiency  of this
Agreement,  the Certificates or of any Mortgage Loan or related  document.  The Trust  Administrator  shall not
be accountable  for the use or application by the Depositor,  the Seller,  the Master Servicer or the Servicers
of any funds paid to the Depositor or the Master  Servicer or any Servicer in respect of the Mortgage  Loans or
deposited in or withdrawn from the  Certificate  Account by the Depositor,  the Seller,  the Master Servicer or
the  Servicers.  The  Trust  Administrator  shall not be  responsible  for the  legality  or  validity  of this
Agreement or the validity,  priority,  perfection or sufficiency of the security for the Certificates issued or
intended  to be issued  hereunder.  The  Trust  Administrator  shall  have no  responsibility  for  filing  any
financing or  continuation  statement in any public office at any time or to otherwise  perfect or maintain the
perfection for any security interest or lien granted to it hereunder or to record this Agreement.

SECTION 10.04. Trust Administrator May Own Certificates.

               The Trust  Administrator in its individual or any other capacity may become the owner or pledgee
of Certificates with the same rights as it would have if it were not the Trust Administrator.

SECTION 10.05. Trust Administrator's Fees and Expenses.

               As compensation for its services  hereunder,  the Trust  Administrator  shall be entitled to the
investment   income  or  other  benefit  derived  from  balances  in  the  Certificate   Account   pursuant  to
Section 3.05(e) (the  "Trust Administrator Fee"). The Trust Administrator and any director,  officer,  employee
or agent of the Trust  Administrator  shall be  indemnified  by DLJMC (or if DLJMC  shall fail to do so, by the
Trust) and held harmless  against any loss,  liability or expense  (including  reasonable  attorney's  fees and
expenses)  (i) incurred in connection with any claim or legal action  relating to (a) this  Agreement,  (b) the
Certificates,  (c) the Custodial Agreement,  or (d) the performance of any of the Trust Administrator's  duties
hereunder or under the Custodial  Agreement,  other than any loss,  liability or expense  incurred by reason of
willful  misfeasance,  bad faith or negligence in the  performance of any of the Trust  Administrator's  duties
hereunder  or  incurred  by reason  of any  action of the Trust  Administrator  taken at the  direction  of the
Certificateholders  and  (ii) resulting  from any error in any tax or information return prepared by the Master
Servicer or a Servicer;  provided,  however, that the sum of (x) such indemnity amounts payable by DLJMC or the
Trust to the Trust  Administrator  pursuant to this  Section 10.05  and (y) the  indemnity  amounts  payable by
DLJMC or the Trust to the Master  Servicer  pursuant to  Section 3.14(c),  shall not exceed  $200,000 per year;
provided,  further,  that any amounts not payable by DLJMC or the Trust to the Trust  Administrator  due to the
preceding  proviso  shall be  payable  by DLJMC (or if DLJMC  fails to do so, by the  Trust) in any  succeeding
year,  subject  to the  aggregate  $200,000  per  annum  limitation  imposed  by the  preceding  proviso.  Such
indemnity  shall  survive  the  termination  of this  Agreement  or the  resignation  or  removal  of the Trust
Administrator  hereunder.  Without  limiting  the  foregoing,  DLJMC (or if DLJMC  fails to do so,  the  Trust)
shall,  except as  otherwise  agreed upon in writing by DLJMC and the Trust  Administrator,  and except for any
such expense,  disbursement  or advance as may arise from the Trust  Administrator's  negligence,  bad faith or
willful  misconduct,  pay or  reimburse  the  Trust  Administrator  (up to a  maximum  of  $150,000),  for  all
reasonable  expenses,  disbursements  and advances  incurred or made by the Trust  Administrator  in accordance
with any of the  provisions  of this  Agreement  with  respect  to:  (A) the  reasonable  compensation  and the
expenses  and  disbursements  of  its  counsel  not  associated  with  the  closing  of  the  issuance  of  the
Certificates,  (B) the reasonable  compensation,  expenses and  disbursements  of any  accountant,  engineer or
appraiser  that  is  not  regularly  employed  by the  Trust  Administrator,  to  the  extent  that  the  Trust
Administrator  must engage such persons to perform acts or services  hereunder  and (C) printing and  engraving
expenses in connection  with preparing any Definitive  Certificates.  In addition,  DLJMC (or if DLJMC fails to
do so, the Trust) shall pay or reimburse the Trust Administrator for  recertification  fees required to be paid
by the Trust  Administrator  pursuant to the Custodial  Agreement.  Except as otherwise  provided  herein,  the
Trust  Administrator  shall not be  entitled  to payment or  reimbursement  for any  routine  ongoing  expenses
incurred by the Trust  Administrator  in the ordinary course of its duties as Trust  Administrator,  Registrar,
Tax Matters Person or Paying Agent hereunder.  Anything in this Agreement to the contrary  notwithstanding,  in
no event shall the Trust  Administrator be liable for special,  indirect or consequential loss or damage of any
kind whatsoever  (including but not limited to lost profits),  even if the Trust Administrator has been advised
of the likelihood of such loss or damage and regardless of the form of action.

SECTION 10.06. Eligibility Requirements for Trust Administrator.

               The Trust  Administrator  hereunder  shall at all times be (a) an  institution  the  deposits of
which are fully insured by the FDIC and (b) a corporation or banking  association  organized and doing business
under the laws of any state or the United States of America,  authorized under such laws to exercise  corporate
trust powers,  having a combined  capital and surplus of at least  $50,000,000  and subject to  supervision  or
examination  by  federal  or state  authority  and  (c) with  respect to every  successor  Trust  Administrator
hereunder an institution  the long-term  unsecured debt  obligations of which are rated at least Baa3 or better
by Moody's and BBB or better by S&P unless the failure of the Trust  Administrator's  long-term  unsecured debt
obligations  to have such ratings  would not result in the lowering of the ratings  originally  assigned to any
Class of  Certificates.  If such  corporation or banking  association  publishes  reports of condition at least
annually,  pursuant to law or to the  requirements of the aforesaid  supervising or examining  authority,  then
for the purposes of this  Section 10.06  the combined  capital and surplus of such  corporation  or association
shall be deemed to be its combined  capital and surplus as set forth in its most recent  report of condition so
published.  In case at any time the Trust  Administrator  shall  cease to be eligible  in  accordance  with the
provisions of this  Section 10.06,  the Trust Administrator shall resign immediately in the manner and with the
effect specified in Section 10.07 hereof.

SECTION 10.07. Resignation and Removal of Trust Administrator.

               The Trust  Administrator may at any time resign and be discharged from the trusts hereby created
by (a) giving  written notice of resignation to the Depositor,  the Seller,  the Trustee,  the Master Servicer,
the Special  Servicer and the  Servicers  and by mailing  notice of  resignation  by first class mail,  postage
prepaid,  to the  Certificateholders  at their  addresses  appearing on the  Certificate  Register,  and to the
Rating  Agencies,  not  less  than  60 days  before  the  date  specified  in  such  notice  when,  subject  to
Section 10.08,  such resignation is to take effect,  and  (b) acceptance by a successor trust  administrator in
accordance with Section 10.08 meeting the qualifications set forth in Section 10.06.

               If at any time the  Trust  Administrator  shall  cease to be  eligible  in  accordance  with the
provisions of  Section 10.06  hereof and shall fail to resign after written  request  thereto by the Depositor,
or if at any time the Trust  Administrator  shall become  incapable of acting,  or shall be adjudged a bankrupt
or insolvent,  or a receiver of the Trust  Administrator  or of its property shall be appointed,  or any public
officer shall take charge or control of the Trust  Administrator  or of its property or affairs for the purpose
of rehabilitation,  conservation or liquidation or if the Trust  Administrator  breaches any of its obligations
or  representations  hereunder,  then the Depositor may remove the Trust  Administrator and appoint a successor
trust  administrator by written  instrument,  in duplicate,  one copy of which instrument shall be delivered to
the Trust  Administrator and one copy to the successor trust  administrator.  The Trust  Administrator may also
be  removed at any time by the  Trustee or the  Holders  of  Certificates  evidencing  not less than 50% of the
Voting Rights evidenced by the  Certificates.  Notice of any removal of the Trust  Administrator and acceptance
of appointment by the successor trust administrator shall be given to the Rating Agencies by the Depositor.

               If no successor trust administrator  shall have been so appointed and have accepted  appointment
within 30 days  after  the  giving of such  notice  of  resignation  or  receipt  of a notice of  removal,  the
resigning Trust  Administrator may, at the Trust Fund's expense,  petition any court of competent  jurisdiction
for the appointment of a successor trust administrator.

               Notwithstanding  the foregoing,  if the Master Servicer shall for any reason no longer be Master
Servicer  hereunder,  at  DLJMC's  request,  the Trust  Administrator  shall  resign,  upon the  selection  and
appointment of a successor trust administrator meeting the qualifications set forth in Section 10.06.

               Any  resignation or removal of the Trust  Administrator  and  appointment  of a successor  trust
administrator  pursuant to any of the provisions of this  Section 10.07  shall become effective upon acceptance
of appointment by the successor trust administrator as provided in Section 10.08 hereof.

SECTION 10.08. Successor Trust Administrator.

               Any successor trust administrator  appointed as provided in Section 10.07  hereof shall execute,
acknowledge and deliver to the Depositor and to its predecessor  trust  administrator  an instrument  accepting
such  appointment  hereunder and thereupon the  resignation or removal of the predecessor  trust  administrator
shall become  effective and such successor  trust  administrator,  without any further act, deed or conveyance,
shall become fully vested with all the rights,  powers,  duties and obligations of its  predecessor  hereunder,
with the like effect as if originally  named as Trust  Administrator  herein.  The  Depositor,  upon receipt of
all  amounts due it  hereunder,  and the  predecessor  trust  administrator  shall  execute  and  deliver  such
instruments  and do such other things as may  reasonably be required for more fully and  certainly  vesting and
confirming in the successor trust administrator all such rights, powers, duties, and obligations.

               No successor  trust  administrator  shall accept  appointment as provided in this  Section 10.08
unless  at the time of such  acceptance  such  successor  trust  administrator  shall  be  eligible  under  the
provisions of  Section 10.06  hereof and its acceptance  shall not adversely  affect the then current rating of
the Certificates.

               Upon  acceptance  of  appointment  by a  successor  trust  administrator  as  provided  in  this
Section 10.08,  the Depositor shall mail notice of the succession of such trust administrator  hereunder to all
Holders of  Certificates at their  addresses as shown in the  Certificate  Register.  If the Depositor fails to
mail such notice within ten days after  acceptance of appointment  by the successor  trust  administrator,  the
successor trust administrator shall cause such notice to be mailed at the expense of the Depositor.

SECTION 10.09. Merger or Consolidation of Trust Administrator.

               Any Person into which the Trust  Administrator  may be merged or  converted or with which it may
be  consolidated  or any Person  resulting  from any merger,  conversion  or  consolidation  to which the Trust
Administrator shall be a party, or any Person succeeding to the business of the Trust  Administrator,  shall be
the  successor of the Trust  Administrator  hereunder,  provided  that such Person shall be eligible  under the
provisions of  Section 10.06  hereof without the execution or filing of any paper or further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding.

SECTION 10.10. Appointment of Co-Trust Administrator or Separate Trust Administrator.

               Notwithstanding any other provisions of this Agreement,  at any time, for the purpose of meeting
any legal  requirements  of any  jurisdiction  in which any part of the Trust  Fund or  property  securing  any
Mortgage  Note may at the time be located,  the Master  Servicer  and the Trust  Administrator  acting  jointly
shall have the power and shall execute and deliver all  instruments to appoint one or more Persons  approved by
the Trust  Administrator  to act as co-trust  administrator or co-trust  administrators  jointly with the Trust
Administrator,  or separate trust  administrator  or separate trust  administrators,  of all or any part of the
Trust Fund,  and to vest in such  Person or Persons,  in such  capacity  and for the benefit of the  applicable
Certificateholders,  such title to the Trust Fund, or any part thereof,  and,  subject to the other  provisions
of this  Section 10.10,  such powers,  duties,  obligations,  rights and trusts as the Master  Servicer and the
Trust  Administrator  may consider  necessary or  desirable.  If the Master  Servicer  shall not have joined in
such  appointment  within  fifteen  days after the receipt by it of a request to do so, or in the case an Event
of Default shall have occurred and be continuing,  the Trust  Administrator  alone shall have the power to make
such  appointment.  No co-trust  administrator or separate trust  administrator  hereunder shall be required to
meet the  terms of  eligibility  as a  successor  trust  administrator  under  Section 10.06  and no  notice to
Certificateholders  of the appointment of any co-trust  administrator or separate trust  administrator shall be
required under Section 10.08.

               Every separate trust administrator and co-trust  administrator shall, to the extent permitted by
law, be appointed and act subject to the following provisions and conditions:

(a)     all rights,  powers, duties and obligations  conferred or imposed upon the Trust Administrator,  except
for any  obligation of the Trust  Administrator  under this  Agreement to advance funds on behalf of the Master
Servicer  or the  Servicer,  shall be  conferred  or  imposed  upon and  exercised  or  performed  by the Trust
Administrator  and such separate trust  administrator  or co-trust  administrator  jointly (it being understood
that such separate trust  administrator or co-trust  administrator is not authorized to act separately  without
the Trust  Administrator  joining in such act),  except to the extent that under any law of any jurisdiction in
which  any  particular  act  or  acts  are to be  performed  by  the  Trust  Administrator  (whether  as  Trust
Administrator  hereunder or as  successor  to the Master  Servicer or the  Servicer),  the Trust  Administrator
shall be incompetent or  unqualified  to perform such act or acts, in which event such rights,  powers,  duties
and  obligations  (including  the  holding  of title  to the  Trust  Fund or any  portion  thereof  in any such
jurisdiction)  shall be  exercised  and  performed  singly by such  separate  trust  administrator  or co-trust
administrator, but solely at the direction of the Trust Administrator;

(b)     no trust  administrator  hereunder shall be held personally  liable by reason of any act or omission of
any other trust administrator hereunder; and

(c)     the Master Servicer and the Trust  Administrator  acting jointly may at any time accept the resignation
of or remove any separate trust administrator or co-trust administrator.

               Any notice,  request or other writing given to the Trust  Administrator  shall be deemed to have
been given to each of the then separate trust  administrators  and co-trust  administrators,  as effectively as
if  given  to  each of  them.  Every  instrument  appointing  any  separate  trust  administrator  or  co-trust
administrator  shall  refer to this  Agreement  and the  conditions  of this  Article  X. Each  separate  trust
administrator and co-trust  administrator,  upon its acceptance of the trusts  conferred,  shall be vested with
the  estates  or  property  specified  in  its  instrument  of  appointment,  either  jointly  with  the  Trust
Administrator  or separately,  as may be provided  therein,  subject to all the  provisions of this  Agreement,
specifically  including every provision of this Agreement  relating to the conduct of,  affecting the liability
of, or affording  protection to, the Trust  Administrator.  Every such instrument shall be filed with the Trust
Administrator and a copy thereof given to the Master Servicer or the Servicers and the Depositor.

               Any separate trust  administrator  or co-trust  administrator  may, at any time,  constitute the
Trust  Administrator,  its  agent or  attorney-in-fact,  with full  power  and  authority,  to the  extent  not
prohibited  by law, to do any lawful act under or in respect of this  Agreement  on its behalf and in its name.
The  Trust  Administrator  shall  not  be  responsible  for  any  action  or  inaction  of any  separate  Trust
Administrator or Co-Trust  Administrator.  If any separate trust administrator or co-trust  administrator shall
die, become incapable of acting,  resign or be removed, all of its estates,  properties,  rights,  remedies and
trusts shall vest in and be exercised by the Trust  Administrator,  to the extent permitted by law, without the
appointment of a new or successor trust administrator.

SECTION 10.11. Office of the Trust Administrator.

               The office of the Trust  Administrator  for  purposes  of receipt of notices  and demands is the
Corporate Trust Office.

SECTION 10.12. Tax Return.

               The Master Servicer and each Servicer,  upon request,  will furnish the Trust Administrator with
all such  information  related to the Mortgage Loans in the possession of the Master  Servicer or such Servicer
as may be reasonably  required in connection  with the  preparation by the Trust  Administrator  of all tax and
information  returns  of the Trust  Fund,  and the Trust  Administrator  shall  sign such  returns.  The Master
Servicer and each  Servicer,  severally  and not  jointly,  shall  indemnify  the Trust  Administrator  for all
reasonable costs,  including legal fees and expenses,  related to errors in such tax returns due to errors only
in such information provided by the Master Servicer or by such Servicer.

SECTION 10.13. Commission Reporting.

(a)     The Trust  Administrator,  each Servicer and the Master  Servicer shall  reasonably  cooperate with the
Depositor in connection  with the Trust's  satisfying  the reporting  requirements  under the Exchange Act. The
Trust  Administrator  shall  prepare on behalf of the  Depositor  any Forms 8-K and 10-K  customary for similar
securities as required by the Exchange Act and the rules and  regulations  of the  Commission  thereunder,  and
the  Depositor  shall  sign and the Trust  Administrator  shall  file (via  EDGAR)  such Forms on behalf of the
Depositor.  The  Depositor  hereby  grants to the Trust  Administrator  a limited  power of attorney to execute
each Form 8-K and file each Form 8-K and Form 10-K on behalf of the  Depositor.  Such power of  attorney  shall
continue  until  the  earlier  of (i)  receipt  by the  Trust  Administrator  from  the  Depositor  of  written
termination of such power of attorney and (ii) the termination of the Trust.

(b)     Each Form 8-K shall be filed by the Trust  Administrator  within 15 days after each Distribution  Date,
with a copy of the  statement  to the  Certificateholders  for such  Distribution  Date as an exhibit  thereto.
Prior to March 31st of the calendar  year  following the calendar year during which the Closing Date occurs (or
such  earlier date as may be required by the Exchange  Act and the rules and  regulations  of the  Commission),
the Trust  Administrator  shall file a Form 10-K,  in substance  as required by  applicable  law or  applicable
Commission staff's  interpretations.  Such Form 10-K shall include as exhibits,  each Servicer's and the Master
Servicer's annual statement of compliance  described under  Section 3.16 and the accountant's  report described
under  Section 3.17,  in each case to the extent they have been timely  delivered  to the Trust  Administrator.
If they are not so timely  delivered,  the Trust  Administrator  shall file an amended Form 10-K including such
documents as exhibits  promptly after they are delivered to the Trust  Administrator.  The Trust  Administrator
shall have no  liability  with  respect to any  failure to  properly  or timely  prepare or file such  periodic
reports  resulting  from  or  relating  to the  Trust  Administrator's  inability  or  failure  to  obtain  any
information  not resulting  from its own negligence or willful  misconduct.  The Form 10-K shall also include a
certification in the form attached hereto as Exhibit T (the "Depositor  Certification"),  which shall be signed
by the senior  officer of the  Depositor in charge of  securitization.  The Trust  Administrator  shall have no
responsibility to file any items other than those specified in this Section 10.13.

(c)     Not later than 15 calendar days before the date on which the Depositor's  annual report on Form 10-K is
required to be filed in accordance  with the Exchange Act and the rules and  regulations of the Commission (or,
if such day is not a Business Day, the  immediately  preceding  Business  Day), the Trust  Administrator  shall
sign a certification  in the form attached hereto as Exhibit U (the "Trust  Administrator  Certification")  for
the benefit of the Depositor and its officers,  directors and affiliates  regarding  certain aspects of items 1
through  3 of the  Depositor  Certification.  In  addition,  the  Trust  Administrator  shall,  subject  to the
provisions of Sections  10.01 and 10.02 hereof,  indemnify and hold harmless the Depositor and each Person,  if
any,  who  "controls"  the  Depositor  within  the  meaning  of the 1933 Act and its  officers,  directors  and
affiliates  from and against any losses,  damages,  penalties,  fines,  forfeitures,  reasonable  and necessary
legal fees and related costs,  judgments and other costs and expenses  arising out of or based upon a breach of
the  Trust  Administrator's  obligations  under  this  Section 10.13  or  any  inaccuracy  made  in  the  Trust
Administrator  Certification.  If the indemnification provided for in this  Section 10.13(c) is  unavailable or
insufficient to hold harmless such Persons,  then the Trust  Administrator  shall contribute to the amount paid
or payable by such Persons as a result of the losses,  claims,  damages or  liabilities of such Persons in such
proportion  as is  appropriate  to reflect the  relative  fault of the  Depositor on the one hand and the Trust
Administrator on the other.  The Trust  Administrator  acknowledges  that the Depositor is relying on the Trust
Administrator's  performance of its obligations  under this  Section 10.13  in order to perform its obligations
under Section 10.13(b) above.

(d)     (i)           Not later than 15 calendar  days before the date on which the  Depositor's  annual report
        on Form 10-K is required to be filed in accordance  with the Exchange Act and the rules and regulations
        of the Commission (or, if such day is not a Business Day, the immediately  preceding Business Day), the
        Master Servicer will deliver to the Depositor and the Trust Administrator an Officer's  Certificate for
        the prior  calendar  year in  substantially  the form of  Exhibit V-1  to this  Agreement.  The  Master
        Servicer agrees to indemnify and hold harmless each of the Depositor,  the Trust Administrator and each
        Person, if any, who "controls" the Depositor or the Trust Administrator  within the meaning of the 1933
        Act and  their  respective  officers  and  directors  against  any and all  losses,  penalties,  fines,
        forfeitures,  legal fees and related costs,  judgments and any other costs, fees and expenses that such
        Person may sustain  arising out of third party claims based on (i) the  failure of the Master  Servicer
        to deliver or cause to be delivered when required any Officer's  Certificate  required pursuant to this
        Section 10.13(d)(i),  or  (ii) any  material  misstatement  or  omission  contained  in  any  Officer's
        Certificate  provided  pursuant to this  Section 10.13(d)(i).  If an event occurs that would  otherwise
        result in an  indemnification  obligation  under clauses  (i) or  (ii) above,  but the  indemnification
        provided for in this  Section 10.13(d)(i) by the Master Servicer is unavailable or insufficient to hold
        harmless such Persons,  then the Master Servicer shall contribute to the amount paid or payable by such
        Persons as a result of the losses,  claims,  damages or liabilities of such Persons in such  proportion
        as is  appropriate  to reflect the relative  fault of the Depositor or Trust  Administrator  on the one
        hand and the Master  Servicer on the other.  The Master  Servicer  acknowledges  that the Depositor and
        the Trust Administrator are relying on the Master Servicer's  performance of its obligations under this
        Agreement in order to perform their respective obligations under this Section 10.13.

(ii)    Not later than 15 calendar days before the date on which the Depositor's  annual report on Form 10-K is
        required  to be  filed in  accordance  with the  Exchange  Act and the  rules  and  regulations  of the
        Commission  (or if such day is not a Business  Day,  the  immediately  preceding  Business  Day),  each
        Servicer,  with  respect to the Mortgage  Loans  serviced by such  Servicer,  will deliver to the Trust
        Administrator,  and the Trust Administrator shall forward to the Depositor and the Master Servicer,  an
        Officer's  Certificate  for the prior  calendar year in  substantially  the form of Exhibit V-2 to this
        Agreement.  Each  Servicer  agrees to indemnify  and hold  harmless  each of the  Depositor,  the Trust
        Administrator,  the Master  Servicer and each Person,  if any, who "controls" the Depositor,  the Trust
        Administrator and the Master Servicer within the meaning of the 1933 Act and their respective  officers
        and directors against any and all losses, penalties, fines, forfeitures,  legal fees and related costs,
        judgments  and any other  costs,  fees and expenses  that such Person may sustain  arising out of third
        party  claims  based on (i) the  failure of such  Servicer  to  deliver or cause to be  delivered  when
        required  any  Officer's  Certificate  required  pursuant  to this  Section 10.13(d)(ii),  or  (ii) any
        material  misstatement or omission  contained in any Officer's  Certificate  provided  pursuant to this
        Section 10.13(d)(ii).  If an event occurs that would otherwise result in an indemnification  obligation
        under clauses (i) or (ii) above,  but the indemnification provided for in this  Section 10.13(d)(ii) by
        such Servicer is unavailable or  insufficient  to hold harmless such Persons,  then such Servicer shall
        contribute to the amount paid or payable by such Persons as a result of the losses,  claims, damages or
        liabilities  of such Persons in such  proportion as is appropriate to reflect the relative fault of the
        Depositor,  Trust  Administrator or the Master Servicer on the one hand and such Servicer on the other.
        Each Servicer  acknowledges  that the Depositor,  the Trust  Administrator  and the Master Servicer are
        relying on such  Servicer's  performance  of its  obligations  under this Agreement in order to perform
        their respective obligations under this Section 10.13.

(e)     Upon any filing with the Commission,  the Trust Administrator shall promptly deliver to the Depositor a
copy of any executed report, statement or information.

(f)     If the  Commission  issues  additional  interpretative  guidance  or  promulgates  additional  rules or
regulations,  or if other changes in applicable law occur,  that would require the reporting  arrangements,  or
the allocation of  responsibilities  with respect  thereto,  described in this  Section 10.13,  to be conducted
differently than as described,  the Depositor,  each Servicer,  the Master Servicer and the Trust Administrator
will reasonably  cooperate to amend the provisions of this  Section 10.13  in order to comply with such amended
reporting  requirements  and  such  amendment  of this  Section 10.13.  Any  such  amendment  shall  be made in
accordance  with  Section 12.01  without the consent of the  Certificateholders,  and may result in a change in
the reports filed by the Trust  Administrator  on behalf of the Trust under the Exchange  Act.  Notwithstanding
the foregoing,  the Depositor,  each Servicer,  the Master  Servicer and the Trust  Administrator  shall not be
obligated to enter into any amendment  pursuant to this  Section 10.13  that adversely  affects its obligations
and immunities under this Agreement.

(g)     Prior  to  January  31 of the  first  year in  which  the  Trust  Administrator  is able to do so under
applicable  law, the Trust  Administrator  shall file a Form 15D  Suspension  Notification  with respect to the
Trust.

SECTION 10.14. Determination of Certificate Index.

               On each Interest  Determination  Date, the Trust  Administrator shall determine each Certificate
Index for the  Accrual  Period  and inform the Master  Servicer  and each  Servicer  of such rate and such rate
shall be final and binding, absent a manifest error of the Trust Administrator.

                                                  ARTICLE XI

        by the Terminating Entity, at its election,  of all Mortgage Loans in such Loan Groups and all property
        acquired in respect of any  remaining  Mortgage  Loan in such Loan  Groups,  which  purchase  right the
        Terminating  Entity may exercise at its sole and exclusive  election as of any Distribution  Date (such
        applicable  Distribution  Date with  respect to such  Mortgage  Loans being  herein  referred to as the
        "Optional  Termination  Date") on or after the date on which the  aggregate  Principal  Balance  of the
        Mortgage  Loans in such Loan  Groups,  at the time of the  purchase is less than or equal to 10% of the
        Aggregate Groups 1-4 Collateral Balance as of the Initial Cut-off Date; or

(ii)    with respect to Loan Group 5, the purchase by the Terminating Entity, at its election,  of all Mortgage
        Loans in such Loan  Group and all property  acquired in respect of any remaining  Mortgage Loan in such

        election as of any Distribution  Date (such applicable  Distribution Date with respect to such Mortgage
        Loans being herein  referred to as the "Optional  Termination  Date") on or after the date on which the
        aggregate  Principal  Balance of the Mortgage Loans in such Loan Group,  at the time of the purchase is
        less than or equal to 10% of the  Aggregate  Loan Group  Balance  for Loan  Group 5  as of the  Initial
        Cut-off Date.

(b)     the later of  (i) twelve  months after the maturity of the last  Mortgage  Loan  remaining in the Trust
Fund,  (ii) the  liquidation  (or any advance with respect  thereto) of the last Mortgage Loan remaining in the
Trust Fund and the disposition of all  REO Property  and (iii) the  distribution to  Certificateholders  of all

(c)     (i) with  respect to Loan  Group 1,  Loan Group 2,  Loan Group 3 and Loan Group 4,  the purchase by the
        Terminating  Auction  Purchaser of all Mortgage Loans in such Loan Groups and all property  acquired in
        respect of any remaining Mortgage Loan in such Loan Group (with respect to Loan Group 1,  Loan Group 2,
        Loan Group 3 and Loan Group 4, the "Trust Collateral") as described below; or

                      (ii)   with respect to Loan Group 5,  the purchase by the Terminating  Auction  Purchaser
        of all Mortgage  Loans in Loan Group 5 and all property  acquired in respect of any remaining  Mortgage
        Loan in such Loan Group (with respect to Loan Group 5, the "Trust Collateral") as described below.

               In no event shall the trust created hereby continue beyond the earlier of (i) the  expiration of
21 years from the death of the last survivor of the  descendants  of Mr. Joseph P. Kennedy,  former  Ambassador
of the  United  States  to Great  Britain,  living  on the date of  execution  of this  Agreement  or  (ii) the
Distribution  Date following the third  anniversary of the scheduled  maturity date of the Mortgage Loan having
the latest scheduled maturity date as of the related Cut-off Date.

               The "Mortgage  Loan  Purchase  Price" for any such  Optional  Termination  shall be equal to the
greater of (a) the sum of (i) 100% of the Stated  Principal  Balance of each  Mortgage  Loan in the  applicable
Loan  Group(s) (other  than in respect of REO Property)  plus accrued and unpaid interest thereon from the date
to which such  interest was paid or advanced at the  applicable  Mortgage  Rate,  to but not  including the Due
Date in the  month of the  final  Distribution  Date (or the Net  Mortgage  Rate with  respect  to any  related
Mortgage Loan currently  serviced by the entity exercising such Optional  Termination) and (ii) with respect to
any  REO Property,  the lesser of (x) the  appraised  value of any  REO Property as determined by the higher of
two  appraisals  completed  by two  independent  appraisers  selected  by the  Depositor  at the expense of the
Depositor and (y) the Stated Principal  Balance of each related Mortgage Loan related to any  REO Property,  in
each case and (iii) any remaining  unreimbursed  Advances,  Servicing Advances and unpaid Servicing Fees (other
than any remaining  unreimbursed  Advances and Servicing Advances and unpaid Servicing Fees, if any, due to the
Terminating  Entity)  and  other  amounts  payable  to the  Trustee  and Trust  Administrator  (the sum of (i),
(ii) and  (iii),  collectively,  the "Par  Value") and (b) the  Fair Market Value of all of the property of the
Trust related to the Loan Group(s) subject to such Optional Termination.

               The "Fair  Market  Value"  shall be the fair  market  value of all of the  property of the Trust
related to the Loan  Group(s)  subject to an  Optional  Termination,  as agreed upon  between  the  Terminating
Entity  and a  majority  of  the  holders  of the  Class AR-L  Certificates;  provided,  however,  that  if the
Terminating  Entity and a majority of the  holders of the  Class AR-L  Certificates  do not agree upon the fair
market value of such property of the Trust,  the Terminating  Entity,  or an agent appointed by the Terminating
Entity,  shall  solicit  bids for such  property of the Trust until it has  received  three bids,  and the Fair
Market  Value shall be equal to the highest of such three bids.  The Trust  Administrator  shall give notice to
the Rating  Agencies of any election to purchase  Mortgage Loans pursuant to this Section and of the applicable
Optional Termination Date.

(d)     On any Distribution Date on or after the date on which the aggregate  Principal Balance of the Mortgage
Loans in Loan  Group 1,  Loan Group 2,  Loan Group 3 and Loan Group 4 is less than 5% of the  Aggregate  Groups
1-4 Collateral Balance as of the Initial Cut-off Date (a "Terminating  Auction Date"), the Trust  Administrator
shall  solicit  bids for the  related  Trust  Collateral  from at least  three  institutions  that are  regular
purchasers  and/or sellers in the secondary market of residential  whole mortgage loans similar to the Mortgage
Loans. If the Trust  Administrator  receives at least three bids for the related Trust  Collateral,  and one of
such bids is equal to or greater  than the Par Value,  the Trust  Administrator  shall sell the  related  Trust
Collateral to the highest bidder (a  "Terminating  Auction  Purchaser") at the price offered by the Terminating
Auction  Purchaser (a "Mortgage Loan Terminating  Auction  Price").  If the Trust  Administrator  receives less
than  three  bids,  or does not  receive  any bid that is equal to or  greater  than the Par  Value,  the Trust
Administrator  shall,  on each six-month  anniversary  of the initial  Terminating  Auction Date,  repeat these
auction  procedures  until the Trust  Administrator  receives  a bid that is equal to or  greater  than the Par
Value,  and upon  receipt  of such bid shall sell the  related  Trust  Collateral  to the  Terminating  Auction
Purchaser at that Mortgage Loan Terminating  Auction Price;  provided,  however,  that the Trust  Administrator
shall  not be  required  to  repeat  these  auction  procedures  on any  Distribution  Date  for any  six-month
anniversary of the initial  Terminating  Auction Date unless the Trust  Administrator  reasonably believes that
there is a  reasonable  likelihood  of  receiving  a bid in excess of the Par  Value.  The Trust  Administrator
shall give notice to the Rating  Agencies  and each  Servicer  that is  servicing  any of the related  Mortgage
Loans of the sale of the related  Trust  Collateral  pursuant to this  Section 11.01  (a  "Terminating  Auction
Sale") and of the Terminating  Auction Date.  Notwithstanding  anything to the contrary herein, the Terminating
Auction Purchaser shall not be the Depositor, DLJMC or any of their respective Affiliates.

(e)     On any Distribution Date on or after the date on which the aggregate  Principal Balance of the Mortgage
Loans in Loan Group 5 is less than 5% of the  Aggregate  Loan Group  Balance for Loan Group 5 as of the Initial
Cut-off Date (a "Terminating  Auction Date"), the Trust  Administrator shall solicit bids for the related Trust
Collateral  from at least  three  institutions  that are regular  purchasers  and/or  sellers in the  secondary
market of  residential  whole  mortgage  loans  similar  to the  Mortgage  Loans.  If the  Trust  Administrator
receives  at least  three bids for the related  Trust  Collateral,  and one of such bids is equal to or greater
than the Par Value,  the Trust  Administrator  shall sell the related Trust Collateral to the highest bidder (a
"Terminating  Auction  Purchaser") at the price offered by the Terminating  Auction Purchaser (a "Mortgage Loan
Terminating  Auction  Price").  If the Trust  Administrator  receives less than three bids, or does not receive
any bid that is equal to or greater  than the Par  Value,  the Trust  Administrator  shall,  on each  six-month
anniversary  of the  initial  Terminating  Auction  Date,  repeat  these  auction  procedures  until  the Trust
Administrator  receives a bid that is equal to or  greater  than the Par  Value,  and upon  receipt of such bid
shall sell the related Trust  Collateral  to the  Terminating  Auction  Purchaser at that Mortgage Loan Auction
Price;  provided,  however,  that the  Trust  Administrator  shall not be  required  to  repeat  these  auction
procedures on any  Distribution  Date for any six-month  anniversary  of the initial  Terminating  Auction Date
unless the Trust  Administrator  reasonably  believes that there is a reasonable  likelihood of receiving a bid
in excess of the Par  Value.  The Trust  Administrator  shall  give  notice  to the  Rating  Agencies  and each
Servicer  that is  servicing  any of the related  Mortgage  Loans of the sale of the related  Trust  Collateral
pursuant  to  this  Section 11.01  (a  "Terminating  Auction  Sale")  and  of  the  Terminating  Auction  Date.
Notwithstanding  anything  to  the  contrary  herein,  the  Terminating  Auction  Purchaser  shall  not  be the
Depositor, DLJMC or any of their respective Affiliates.

SECTION 11.02. Determination of the Terminating Entity.

(a)     If any Servicer intends to be the Terminating  Entity, such party must give written notice to the Trust
Administrator  no later  than  twenty  (20)  days  prior to the first day of the  Optional  Termination  Notice
Period.  Such notice  shall also  indicate  the Loan  Group(s) of the Mortgage  Loans to be  repurchased.  Upon
receiving such notice,  the Trust  Administrator  shall immediately  request from DLJMC and DLJMC shall deliver
no later than  seventeen  (17) days prior to the first day of the Optional  Termination  Notice Period a letter
indicating  whether or not DLJMC retains the  servicing  rights to any Mortgage Loan in any of the related Loan
Groups.

(b)     (A)           With respect to the purchase of the Mortgage  Loans in Loan Group 1,  Loan Group 2,  Loan
     Group 3 and Loan Group 4, the Trust Administrator shall determine the "Terminating Entity" as follows:

                             (i)    DLJMC,  if it is the owner of the  servicing  rights  with  respect  to any
          such Mortgage Loans on the Optional Termination Date;

                             (ii)   SPS, if (a) DLJMC is not the owner of the  servicing  rights  with  respect
          to any such Mortgage  Loans on the Optional  Termination  Date and (b) SPS is a Servicer with respect
          to any such  Mortgage  Loans on the Optional  Termination  Date and SPS has given notice to the Trust
          Administrator pursuant to Section 11.02(a) above; or

                             (iii)  the Majority  Servicer on the Optional  Termination  Date,  if (a) DLJMC is
          not the owner of the  servicing  rights  with  respect  to any such  Mortgage  Loans on the  Optional
          Termination  Date and (b) SPS has not given  notice to the Trust  Administrator  pursuant  to Section
          11.02(a) above.

                      (B)    With  respect to the  purchase of the Mortgage  Loans in Loan  Group 5,  the Trust
     Administrator shall determine the "Terminating Entity" as follows:

                             (i)    DLJMC,  if it is the owner of the  servicing  rights  with  respect  to any
          such Mortgage Loans on the Optional Termination Date;

                             (ii)   SPS, if (a) DLJMC is not the owner of the  servicing  rights  with  respect
          to any such Mortgage  Loans on the Optional  Termination  Date and (b) SPS is a Servicer with respect
          to any such  Mortgage  Loans on the Optional  Termination  Date and SPS has given notice to the Trust
          Administrator pursuant to Section 11.02(a) above; or

                             (iii)  the Majority  Servicer on the Optional  Termination  Date,  if (a) DLJMC is
          not the owner of the  servicing  rights  with  respect  to any such  Mortgage  Loans on the  Optional
          Termination  Date and (b) SPS has not given  notice to the Trust  Administrator  pursuant  to Section
          11.02(a) above.

(c)     No later than fifteen (15) days prior to the first day of the Optional  Termination  Notice Period, the
Trust  Administrator  shall provide  notice to each Servicer that is a servicer of any of the Mortgage Loans in
the related Loan Group(s) of the identity of the Terminating Entity for such Loan Group(s).

SECTION 11.03. Procedure Upon Optional Termination or Terminating Auction Sale.

(a)     In case of any Optional  Termination,  the Terminating  Entity shall, no later than ten (10) days prior
to the first day of the Optional  Termination  Notice  Period,  notify the Trustee and Trust  Administrator  of
such Optional  Termination  Date and of the  applicable  purchase  price of the Mortgage Loans to be purchased.
Upon  purchase  by the  Terminating  Entity  of  any  Mortgage  Loans  pursuant  to  Section 11.01,  the  Trust
Administrator shall notify each Servicer that is servicing any of such Mortgage Loans of such purchase.

(b)     Any purchase of the Mortgage Loans by the Terminating  Entity shall be made on an Optional  Termination
Date by deposit of the  applicable  purchase price into the  Certificate  Account,  as  applicable,  before the
Distribution  Date on  which  such  purchase  is  effected.  Upon  receipt  by the  Trust  Administrator  of an
Officer's  Certificate of the Terminating  Entity  certifying as to the deposit of such purchase price into the
Certificate Account,  the Trustee,  the Trust Administrator and each co-trust  administrator and separate trust
administrator,  if any,  then acting as such under this  Agreement,  shall,  upon request and at the expense of
the  Terminating  Entity  execute and  deliver all such  instruments  of transfer or  assignment,  in each case
without recourse,  as shall be reasonably  requested by the Terminating Entity to vest title in the Terminating
Entity in the  Mortgage  Loans so  purchased  and shall  transfer  or  deliver  to the  Terminating  Entity the
purchased  Mortgage  Loans.  Any  distributions  on the  Mortgage  Loans which have been subject to an Optional
Termination  received by the Trust  Administrator  subsequent to (or with respect to any period  subsequent to)
the Optional Termination Date shall be promptly remitted by it to the Terminating Entity.

(c)     Any purchase of the Trust Collateral by the related  Terminating  Auction Purchaser shall be made on an
Terminating  Auction  Date by receipt of the Trust  Administrator  of the  related  Mortgage  Loan  Terminating
Auction Price from the Terminating  Auction  Purchaser,  and deposit of such Mortgage Loan Terminating  Auction
Price into the  Certificate  Account by the Trust  Administrator  before  the  Distribution  Date on which such
purchase is effected.  Upon deposit of such purchase price into the  Certificate  Account,  the Trustee and the
Trust Administrator and each co-trust  administrator and separate trust  administrator,  if any, then acting as
such under this  Agreement,  shall,  upon  request  and at the  expense of the  Terminating  Auction  Purchaser
execute and deliver all such  instruments of transfer or assignment,  in each case without  recourse,  as shall
be  reasonably  requested  by the  Terminating  Auction  Purchaser  to vest  title in the  Terminating  Auction
Purchaser  in the Trust  Collateral  so  purchased  and shall  transfer or deliver to the  Terminating  Auction
Purchaser the purchased Trust Collateral.

(d)     Notice  of the  Distribution  Date  on  which  the  Trust  Administrator  anticipates  that  the  final
distribution shall be made on a Class of Certificates (whether upon Optional  Termination,  Terminating Auction
Sale or otherwise),  shall be given promptly by the Trust  Administrator  by first class mail to Holders of the
affected  Certificates.  Such notice  shall be mailed no earlier  than the 15th day and not later than the 10th
day  preceding  the  applicable  Optional  Termination  Date,   Terminating  Auction  Date  or  date  of  final
distribution,  as the case may be.  Such  notice  shall  specify  (i) the  Distribution  Date upon which  final
distribution on the affected  Certificates  will be made upon  presentation and surrender of such  Certificates
at the office or agency  therein  designated,  (ii) the  amount of such final  distribution  and (iii) that the
Record Date otherwise  applicable to such  Distribution Date is not applicable,  such  distribution  being made
only upon  presentation  and  surrender  of such  Certificates  at the  office or  agency  maintained  for such
purposes (the address of which shall be set forth in such notice).

(e)     In the event that any  Certificateholders  shall not surrender Certificates for cancellation within six
months after the date specified in the above mentioned  written notice,  the Trust  Administrator  shall give a
second  written  notice  to  the  remaining  such   Certificateholders  to  surrender  their  Certificates  for
cancellation and receive the final  distribution  with respect  thereto.  If within six months after the second
notice all the  Certificates  shall not have been surrendered for  cancellation,  the Trust  Administrator  may
take  appropriate  steps,  or may  appoint  an  agent to take  appropriate  steps,  to  contact  the  remaining
Certificateholders  concerning  surrender of their Certificates,  and the cost thereof shall be paid out of the
funds and other assets which remain subject to the Trust Fund.

(f)     Notwithstanding  anything  to the  contrary  herein,  the  occurrence  of an  Optional  Termination  or
Terminating  Auction  Sale shall be subject to, and shall in no way  adversely  affect the right of Wells Fargo
to continue  servicing  and  collecting  its  Servicing  Fee for any Wells Fargo  Serviced  Mortgage  Loan that
remains outstanding at the time of such Optional Termination or Terminating Auction Sale.

SECTION 11.04. Additional Termination Requirements.

(a)     In the event the Terminating  Entity  exercises its purchase option pursuant to  Section 11.01(A)  or a
Terminating Auction Sale shall have occurred pursuant to  Section 11.01(c),  the related subsidiary REMIC shall
be terminated  in  accordance  with the  following  additional  requirements,  unless the Trustee and the Trust
Administrator  have  received  an  Opinion  of  Counsel  to the  effect  that the  failure  to comply  with the
requirements of this  Section will  not (i) result in the imposition of taxes on a "prohibited  transaction" of
any REMIC  created  hereunder,  as described in  Section 860F  of the Code,  or  (ii) cause  any REMIC  created
hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(i)     within  90 days  prior to the final  Distribution  Date set forth in the  notice  given by  Terminating
        Entity  under  Section 11.03,  the Holder of the Residual  Certificates  shall adopt a plan of complete
        liquidation for the related REMIC; and

(ii)    at or after the time of  adoption  of any such plan of  complete  liquidation  for such REMIC and at or
        prior to the final  Distribution  Date,  the Trustee  shall sell all of the assets of such REMIC to the
        Depositor for cash.

(b)     Upon the exercise of an Optional  Termination  by the  Terminating  Entity or upon the  occurrence of a
Terminating  Auction  Sale in respect of either  REMIC I or  REMIC II,  as  applicable,  pursuant to  paragraph
(a) of this Section,  followed by the exercise of an Optional Termination by the Terminating Entity or upon the
occurrence  of a  Terminating  Auction  Sale in  respect of the  remaining  subsidiary  REMIC  (the  "Remaining
Subsidiary  REMIC") pursuant to Section 11.01,  each remaining REMIC shall be terminated in accordance with the
following additional  requirements,  unless the Trustee and the Trust Administrator have received an Opinion of
Counsel to the effect that the failure to comply with the  requirements of this  Section will not (i) result in
the imposition of taxes on a "prohibited  transaction"  of a REMIC,  as described in  Section 860F of the Code,
or (ii) cause any REMIC created  hereunder to fail to qualify as a REMIC at any time that any  Certificates are
outstanding:

(i)     concurrently with the adoption of the plan of complete  liquidation of the Remaining  Subsidiary REMIC,
        as set forth in paragraph (a) of this Section, the Holder of the Residual Certificates,  as applicable,
        shall adopt a plan of complete liquidation of each remaining REMIC; and

(ii)    at or after the time of  adoption  of any such plan of  complete  liquidation  for each such  remaining
        REMIC, at or prior to the final  Distribution Date of the Remaining  Subsidiary REMIC to be terminated,
        the Trustee shall sell all of the assets of each such remaining REMIC to the Depositor for cash.

(c)     By its acceptance of a Residual  Certificate,  the Holder thereof hereby agrees to adopt such a plan of
complete  liquidation  and to take such other action in connection  therewith as may be reasonably  required to
liquidate and otherwise terminate any REMIC created pursuant to this Agreement.

consent of any of the Certificateholders,

(i)     to cure any error or ambiguity,

(ii)    to correct or supplement  any  provisions  herein that may be  inconsistent  with any other  provisions
        herein or in the Prospectus Supplement,

(iii)   to modify,  eliminate or add to any of its provisions to such extent as shall be necessary or desirable
        to  maintain  the  qualification  of the Trust  Fund as a REMIC at all times  that any  Certificate  is
        outstanding  or to avoid or minimize the risk of the  imposition of any federal income tax on the Trust
        Fund pursuant to the Code that would be a claim  against the Trust Fund,  provided that the Trustee has
        received  an Opinion  of  Counsel to the effect  that (A) such  action is  necessary  or  desirable  to
        maintain  such  qualification  or to avoid or minimize the risk of the  imposition  of any such federal
        income tax and (B) such  action  will not  adversely  affect the status of the Trust Fund as a REMIC or
        adversely affect in any material respect the interests of any Certificateholder,

(iv)    in connection with the appointment of a successor servicer,  to modify,  eliminate or add to any of the
        servicing provisions, provided the Rating Agencies confirm the rating of the Certificates, or

(v)     to make any other  provisions  with respect to matters or questions  arising under this  Agreement that
        are not materially inconsistent with the provisions of this Agreement,  provided that such action shall
        not  adversely  affect in any  material  respect the  interests  of any  Certificateholder  or cause an
        Adverse REMIC Event.  Any Amendment  pursuant to  Section 12.01(a)(v) shall  not be deemed to adversely
        affect in any material  respect the  interests of any  Certificateholder  if a letter is obtained  from
        each Rating Agency  stating that such  amendment  would not result in the  downgrading or withdrawal of
        the respective ratings then assigned to the Certificates.

(b)     Except  as  provided  in  Section 12.01(c),  this  Agreement  may be  amended  from time to time by the
Depositor,  the Master Servicer,  the Servicers,  the Back-Up Servicer,  the Special Servicer,  the Seller, the
Trust  Administrator  and the  Trustee  with the  consent of the  Holders of  Certificates  evidencing,  in the

provisions  to or  changing  in any  manner  or  eliminating  any of the  provisions  of this  Agreement  or of
modifying  in any  manner  the  rights of the  Holders of the  Certificates;  provided,  however,  that no such
amendment  may  (i) reduce  in any  manner  the  amount  of,  delay the timing of or change the manner in which
payments  received on or with  respect to Mortgage  Loans are  required to be  distributed  with respect to any
Certificate  without  the  consent of the Holder of such  Certificate,  (ii) adversely  affect in any  material
respect  the  interests  of the  Holders  of a  Class of  Certificates  in a manner  other than as set forth in
(i) above  without the consent of the Holders of  Certificates  evidencing  not less than 66 2/3% of the Voting
Rights of such  Class,  (iii) reduce  the  aforesaid  percentages  of Voting  Rights,  the holders of which are
required to consent to any such  amendment  without the consent of 100% of the Holders of  Certificates  of the
Class affected  thereby,  (iv) change  the  percentage of the Stated  Principal  Balance of the Mortgage  Loans
specified in  Section 11.01(a) relating  to optional  termination  of the Trust Fund, (v) change the percentage

               It shall not be necessary for the consent of  Certificateholders  under this Section to  approve
the  particular  form of any proposed  amendment,  but it shall be sufficient if such consent shall approve the
substance  thereof.  The  manner  of  obtaining  such  consents  and of  evidencing  the  authorization  of the
execution  thereof  by  Certificateholders  shall  be  subject  to such  reasonable  regulations  as the  Trust
Administrator may prescribe.

(c)     This  Agreement may be amended from time to time by the  Depositor,  the Master  Servicer,  the Special
Servicer,  the Servicers,  the Back-Up  Servicer,  the Trust  Administrator  and the Trustee for the purpose of
making one or more REMIC  elections  with  respect to one or more  Classes  of  Certificates  delivered  to the
Trustee and issuing one or more  additional  classes of certificates  representing  interests in the Classes of
Certificates delivered to the Trustee;  provided,  however, such amendment shall require the consent of 100% of
the  Holders  of the  Certificates  of the  Class or  Classes  delivered  to the Trust  Administrator  and such
amendment shall not cause an Adverse REMIC Event.

(d)     Promptly after the execution of any amendment to this Agreement,  the Trust Administrator shall furnish
written notification of the substance of such amendment to each Certificateholder, and the Rating Agencies.

(e)     Prior  to the  execution  of any  amendment  to this  Agreement,  each  of the  Trustee  and the  Trust
Administrator  shall receive and be entitled to  conclusively  rely on an Opinion of Counsel (at the expense of
the Person  seeking such  amendment)  stating that the execution of such  amendment is authorized and permitted
by this  Agreement.  The Trustee and the Trust  Administrator  may, but shall not be  obligated  to, enter into
any such amendment which affects the Trustee's or the Trust  Administrator's  own rights,  duties or immunities
under this Agreement.

(f)     The Master Servicer and the Trust Administrator may consent to any amendment of a Designated  Servicing
Agreement  to make any other  provisions  with respect to matters or questions  arising  under such  Designated
Servicing  Agreement  or this  Agreement  that are not  materially  inconsistent  with the  provisions  of such
Designated  Servicing  Agreement and this  Agreement,  provided that such action shall not adversely  affect in
any material  respect the interests of any  Certificateholder  or cause an Adverse  REMIC Event.  Any amendment
pursuant  to this  Section 12.01(f) shall  not be  deemed  to  adversely  affect in any  material  respect  the
interests  of any  Certificateholders  if a letter  is  obtained  from each  Rating  Agency  stating  that such
amendment  would not result in the  downgrading  or withdrawal of the  respective  ratings then assigned to the
Certificates.

(g)     Neither the Master Servicer nor the Trust  Administrator shall consent to any amendment of a Designated
Servicing  Agreement  which shall  adversely  affect in any material  respect the interests of the Holders of a
Class of  Certificates  without the consent of the Holders of Certificates  evidencing not less than 66-2/3% of
the Voting Rights of such Class.

               It shall not be necessary for the consent of  Certificateholders  under this Section to  approve
the particular form of any proposed amendment of a Designated Servicing  Agreement,  but it shall be sufficient
if such consent shall approve the substance  thereof.  The manner of obtaining  such consents and of evidencing
the  authorization  of the  execution  thereof  by  Certificateholders  shall  be  subject  to such  reasonable
regulations as the Trust Administrator may prescribe.

               Promptly after the execution of any amendment to a Designated  Servicing  Agreement  pursuant to
this  Section 12.01(f) or  (g), the Trust Administrator  shall furnish,  upon written notice of such amendment,
written notification of the substance of such amendment to each Certificateholder, and the Rating Agencies.

(h)     Notwithstanding any other provision of this Agreement,  no amendment shall be made affecting the rights
of the Holders of the Class P  Certificates to receive Assigned  Prepayment  Premiums,  including any amendment
to Section 3.23, without the consent of 100% of the Holders of the Class P Certificates.

SECTION 12.02. Recordation of Agreement; Counterparts.

(a)     This Agreement (other than Schedule I) is subject to recordation in all appropriate  public offices for
real  property  records  in all the  counties  or other  comparable  jurisdictions  in which  any or all of the
Mortgaged  Properties are situated,  and in any other  appropriate  public recording office or elsewhere.  Such
recordation,  if any,  shall be  effected by the  Depositor  at its  expense,  but only upon  direction  by the
Trustee  (acting at the direction of the holders of  Certificates  evidencing a majority of the aggregate Class
Principal  Balance)  accompanied  by an Opinion of Counsel  (at the  Depositor's  expense)  to the effect  that
non-recordation materially and adversely affects the interests of the Certificateholders.

(b)     For the purpose of  facilitating  the  recordation of this  Agreement as herein  provided and for other
purposes,  this  Agreement  may be  executed  simultaneously  in any  number  of  counterparts,  each of  which
counterparts  shall be deemed to be an original,  and such  counterparts  shall constitute but one and the same
instrument.

SECTION 12.03. Governing Law.

               THIS AGREEMENT  SHALL BE CONSTRUED IN ACCORDANCE  WITH AND GOVERNED BY THE  SUBSTANTIVE  LAWS OF
THE  STATE OF NEW YORK  APPLICABLE  TO  AGREEMENTS  MADE AND TO BE  PERFORMED  IN THE STATE OF NEW YORK AND THE
OBLIGATIONS,  RIGHTS AND  REMEDIES OF THE PARTIES  HERETO AND THE  CERTIFICATEHOLDERS  SHALL BE  DETERMINED  IN

SECTION 12.04. Intention of Parties.

(a)     It is the express intent of the Depositor,  the Seller, the Master Servicer,  the Special Servicer, the
Servicers,  the Trust  Administrator and the Trustee that (i) the  conveyance by DLJMC of the Mortgage Loans to
the Depositor  pursuant to the Assignment and Assumption  Agreement and (v) the  conveyance by the Depositor to
the Trustee as provided for in Section 2.01 of each of the Seller's and Depositor's  right,  title and interest
in and to the  Mortgage  Loans  be,  and be  construed  as, an  absolute  sale and  assignment  by DLJMC to the
Depositor   and  by  the   Depositor   to  the  Trustee  of  the   Mortgage   Loans  for  the  benefit  of  the
Certificateholders.  Further,  it is not intended that any  conveyance be deemed to be a pledge of the Mortgage
Loans by DLJMC to the  Depositor  or by the  Depositor  to the  Trustee  to secure a debt or other  obligation.
However,  in the  event  that the  Mortgage  Loans  are held to be  property  of  DLJMC  or the  Depositor,  as
applicable,  or if for any reason the Assignment  and Assumption  Agreement or this Agreement is held or deemed
to create a security  interest in the Mortgage  Loans,  then it is intended that (i) this  Agreement shall also
be  deemed  to be a  security  agreement  within  the  meaning  of  Articles  8 and 9 of the New  York  Uniform
Commercial Code and the Uniform  Commercial Code of any other  applicable  jurisdiction;  (ii) the  conveyances
provided for in  Section 2.01  shall be deemed to be a grant by the Seller and the  Depositor to the Trustee on
behalf of the  Certificateholders,  to secure payment in full of the Secured Obligations (as defined below), of
a security  interest in all of the  Seller's and the  Depositor's  right  (including  the power to convey title
thereto),  title  and  interest,  whether  now  owned or  hereafter  acquired,  in and to the  Mortgage  Loans,
including the Mortgage  Notes,  the Mortgages,  any related  insurance  policies and all other documents in the
related Mortgage Files, and all accounts,  contract rights,  general intangibles,  chattel paper,  instruments,
documents,  money, deposit accounts,  certificates of deposit,  goods, letters of credit, advices of credit and
uncertificated  securities  consisting of, arising from or relating to (A) the Mortgage  Loans,  including with
respect to each Mortgage Loan, the Mortgage Note and related  Mortgage,  and all other documents in the related
Trustee Mortgage Files,  and including any Qualified  Substitute  Mortgage Loans; (B) pool insurance  policies,
hazard  insurance  policies  and  any  bankruptcy  bond  relating  to the  foregoing,  if  applicable;  (C) the
Certificate  Account;  (D) the  Collection  Account;  (E) all amounts  payable  after the  Cut-off  Date to the
holders of the Mortgage Loans in accordance  with the terms  thereof;  (F) all income,  payments,  proceeds and
products of the conversion,  voluntary or involuntary,  of the foregoing into cash, instruments,  securities or
other  property,  including  without  limitation  all  amounts  from  time to  time  held  or  invested  in the
Certificate Account,  whether in the form of cash, instruments,  securities or other property; and (G) all cash
and non-cash  proceeds of any of the foregoing;  (iii) the  possession by the Trustee or any other agent of the
Trustee of  Mortgage  Notes or such other  items of  property  as  constitute  instruments,  money,  documents,
advices of credit, letters of credit, goods,  certificated  securities or chattel paper shall be deemed to be a
"possession  by the secured  party," or  possession  by a purchaser or a person  designated  by him or her, for
purposes of perfecting  the security  interest  pursuant to the Uniform  Commercial  Code  (including,  without
limitation,  Sections 9-313,  8-313 or 8-321 thereof); and (iv) notifications to persons holding such property,
and  acknowledgments,   receipts  or  confirmations  from  persons  holding  such  property,  shall  be  deemed
notifications to, or acknowledgments,  receipts or confirmations  from,  financial  intermediaries,  securities
intermediaries,  bailees or agents (as  applicable) of the Trustee for the purpose of perfecting  such security
interest under  applicable law.  "Secured  Obligations"  means (i) the rights of each  Certificateholder  to be
paid any  amount  owed to it under  this  Agreement  and  (ii) all  other  obligations  of the  Seller  and the
Depositor under this Agreement and the Assignment and Assumption Agreement.

(b)     The Seller and the Depositor,  and, at the Depositor's direction, the Master Servicer or the Servicers,
the Trustee  and the Trust  Administrator,  shall,  to the extent  consistent  with this  Agreement,  take such
reasonable  actions as may be  necessary  to ensure that,  if this  Agreement  were deemed to create a security
interest in the Mortgage Loans and the other property  described above,  such security interest would be deemed
to be a perfected  security  interest of first  priority as applicable.  The Depositor  shall prepare and file,
at the related  Servicer's  expense,  all filings  necessary  to maintain  the  effectiveness  of any  original
filings  necessary under the Uniform  Commercial Code as in effect in any jurisdiction to perfect the Trustee's
security interest in or lien on the Mortgage Loans, including without limitation  (i) continuation  statements,
and (ii) such  other  statements as may be occasioned by any transfer of any interest of the Master Servicer or
any Servicer or the Depositor in any Mortgage Loan.

SECTION 12.05. Notices.

for any reason whatsoever held invalid,  then such covenants,  agreements,  provisions or terms shall be deemed
severable from the remaining covenants,  agreements,  provisions or terms of this Agreement and shall in no way
affect the validity or  enforceability  of the other provisions of this Agreement or of the Certificates or the
rights of the Holders thereof.

SECTION 12.07. Limitation on Rights of Certificateholders.

               The death or incapacity of any  Certificateholder  shall not operate to terminate this Agreement
or the Trust Fund, nor entitle such  Certificateholder's  legal  representative or heirs to claim an accounting
or to take any action or commence any  proceeding  in any court for a petition or winding up of the Trust Fund,
or otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

               No  Certificateholder  shall have any right to vote (except as provided herein) or in any manner
otherwise  control the operation and management of the Trust Fund, or the  obligations  of the parties  hereto,
nor shall  anything  herein set forth or  contained  in the terms of the  Certificates  be  construed  so as to
constitute the  Certificateholders  from time to time as partners or members of an  association;  nor shall any
Certificateholder  be under any  liability  to any third party by reason of any action  taken by the parties to
this Agreement pursuant to any provision hereof.

               No  Certificateholder  shall have any right by virtue or by availing itself of any provisions of
this  Agreement to institute  any suit,  action or proceeding in equity or at law upon or under or with respect
to this Agreement,  unless such Holder previously shall have given to the Trust  Administrator a written notice
of an Event of  Default  and of the  continuance  thereof,  as  provided  herein,  and  unless  the  Holders of
Certificates  evidencing not less than 25% of the Voting Rights evidenced by the  Certificates  shall also have
made written  request upon the Trust  Administrator  to institute  such action,  suit or  proceeding in its own
name as Trust  Administrator  hereunder  and shall have  offered  to the Trust  Administrator  such  reasonable
indemnity as it may require against the costs,  expenses,  and  liabilities to be incurred  therein or thereby,
and the Trust  Administrator,  for 60 days after its receipt of such  notice,  request and offer of  indemnity,
shall have  neglected or refused to institute any such action,  suit or  proceeding;  it being  understood  and
intended, and being expressly covenanted by each  Certificateholder with every other  Certificateholder and the
Trust  Administrator,  that no one or more Holders of Certificates  shall have any right in any manner whatever
by virtue or by availing  itself or  themselves  of any  provisions  of this  Agreement  to affect,  disturb or
prejudice the rights of the Holders of any other of the  Certificates,  or to obtain or seek to obtain priority
over or  preference  to any other such  Holder or to enforce  any right  under  this  Agreement,  except in the
manner  herein  provided  and for  the  common  benefit  of all  Certificateholders.  For  the  protection  and
enforcement  of the  provisions  of  this  Section 12.07,  each  and  every  Certificateholder  and  the  Trust
Administrator shall be entitled to such relief as can be given either at law or in equity.

SECTION 12.08. Certificates Nonassessable and Fully Paid.

               It is the intention of the Depositor that Certificateholders  shall not be personally liable for
obligations of the Trust Fund, that the interests in the Trust Fund  represented by the  Certificates  shall be
nonassessable for any reason  whatsoever,  and that the Certificates,  upon due  authentication  thereof by the
Trust Administrator pursuant to this Agreement, are and shall be deemed fully paid.

SECTION 12.09. Protection of Assets.

               Except for transactions and activities entered into in connection with the  securitization  that

(i)     borrow money or issue debt;

(ii)    merge with another entity, reorganize, liquidate or sell assets; or

(iii)   engage in any business or activities.

               Each party to this  agreement  agrees that it will not file an involuntary  bankruptcy  petition
against  the  Trust  Fund or  initiate  any  other  form of  insolvency  proceeding  until  366 days  after the
Certificates have been paid.

SECTION 12.10. Non-Solicitation.

               From and after  the date of this  Agreement,  each of the  Depositor,  the  Seller,  the  Master
Servicer,  the Servicers,  the Trust  Administrator  and the Trustee agrees that it will not take any action or
permit or cause any action to be taken by any of its agents or affiliates,  or by any  independent  contractors
on any such party's behalf,  to personally,  by telephone,  by mail, or electronically by e-mail or through the
Interest or  otherwise,  solicit the  borrower or obligor  under any Mortgage  Loan to  refinance  the Mortgage
Loan,  in whole or in part.  Notwithstanding  the  foregoing,  it is  understood  and  agreed  that  promotions
undertaken by the Depositor,  the Seller,  the Master Servicer,  any Servicer,  the Trust  Administrator or the
Trustee or any  affiliate of any such party that  originates  mortgage  loans in the normal  course,  which are
directed to the general public at large, or segments  thereof,  including,  without  limitation,  mass mailings
based on  commercially  acquired  mailing lists or newspaper,  radio and  television  advertisements  shall not
constitute  solicitation  under this  Section 12.10,  provided,  that no segment of the  general  public  shall
consist  primarily of the borrowers or obligors under the Mortgage  Loans.  None of the Depositor,  the Seller,
the Master Servicer,  a Servicer,  the Trust  Administrator or the Trustee shall permit the sale of the name of
any Mortgagor or any list of names that consist primarily of the Mortgages to any Person.

the  information  provided  pursuant to  Section 13.01(a).  The advice may include  comparable  analysis of the

Such advice may also take the form of benchmark  comparisons  that identify and interpret  SPS's  strengths and
weaknesses relative to similar, unidentified servicers in the industry.

(b)     Each  party to the  Agreement  acknowledges  that the Master  Servicer's  advice is made in the form of
recommendations,  and that the Master  Servicer does not have the right to direct SPS in performing  its duties

transfer is made pursuant to an effective  registration  statement  under the Securities Act and any applicable

event that a transfer is to be made in reliance  upon an exemption  from the  Securities  Act and such laws, in
order to assure  compliance  with the Securities Act and such laws,  the  Certificateholder  desiring to effect
such  transfer  and  such   Certificateholder's   prospective  transferee  shall  each  certify  to  the  Trust
Administrator  in writing the facts  surrounding  the transfer and  (i) deliver a letter in  substantially  the

        Pursuant to Section 6.02(f) of the Agreement,  no transfer of an ERISA-Restricted  Certificate shall be
made unless the Trustee  shall have received  either (i) a  representation  letter from the  transferee of such
ERISA-Restricted   Certificate,   acceptable  to  and  in  form  and  substance   satisfactory   to  the  Trust
Administrator,  to the effect that such  transferee is not an employee  benefit plan or arrangement  subject to
Section 406  of  ERISA or  Section 4975  of the  Code,  or a  person  using  the  assets  of any  such  plan or
arrangement  which  representation  letter shall not be an expense of the Trustee,  the Trust  Administrator or
the Trust Fund,  (ii) if the purchaser is an insurance  company and the  ERISA-Restricted  Certificate has been
the subject of an  ERISA-Qualifying  Underwriting,  a representation that the purchaser is an insurance company
which is purchasing such Certificates  with funds contained in an "insurance  company general account" (as such
term is defined in  Section V(e) of Prohibited  Transaction  Class Exemption 95-60 ("PTCE 95-60")) and that the
purchase and holding of such  Certificate  are covered  under  Sections I and III of PTCE 95-60 or (iii) in the
case of any such  ERISA-Restricted  Certificate  presented for  registration in the name of an employee benefit
plan subject to ERISA or Section 4975 of the Code (or comparable provisions of any subsequent  enactments),  or
a person  using  such  plan's  or  arrangement's  assets,  an  Opinion  of  Counsel  satisfactory  to the Trust
Administrator  to the effect that the  purchase or holding of such  Certificate  will not result in  prohibited
transactions  under  Section 406 of ERISA and/or  Section 4975  of the Code and will not subject the Depositor,
the Trustee, the Trust  Administrator,  the Master Servicer or any other Servicer to any obligation in addition
to those  undertaken  in this  Agreement,  which  Opinion of Counsel shall not be an expense of such parties or
the Trust Fund.  In the event the  representations  referred to in the  preceding  sentence are not  furnished,
such  representation  shall be deemed to have been made to the  trustee by the  transferee's  acceptance  of an
ERISA-Restricted  Certificate  or by any  beneficial  owner who  purchases an interest in this  certificate  in
book-entry  form.  In  the  event  that  a  representation   is  violated,   or  any  attempt  to  transfer  an
ERISA-Restricted  Certificate  to a plan or  arrangement  or person using a plan's or  arrangement's  assets is
attempted  without  the  delivery  to the  Trustee of the Opinion of Counsel  described  above,  the  attempted

unless the Trustee  shall have  received a  representation  letter  from the  transferee  of such  Certificate,
acceptable  to and in form and  substance  satisfactory  to the Trust  Administrator,  to the effect  that such

each  person  holding or  acquiring  an  Ownership  Interest in this Class AR-L  Certificate  must agree not to
transfer an Ownership  Interest in this Class AR-L  Certificate  if it has actual  knowledge  that the proposed
transferee  is not a  Permitted  Transferee  and (v) any  attempted  or  purported  transfer  of any  Ownership
Interest in this Class AR-L  Certificate  in violation of such  restrictions  will be absolutely  null and void
and will vest no rights in the purported transferee.

                      Credit Suisse First Boston Mortgage Securities Corp., as Depositor

        This  Certificate  does not evidence an obligation  of, or an interest in, and is not guaranteed by the
Depositor,  the Seller,  the Master Servicer,  the Servicers,  the Special  Servicer,  the Trustee or the Trust

        This certifies that  _____________________________,  is the registered owner of the Percentage Interest
evidenced by this  Certificate  (obtained by dividing the  denomination of this Certificate by the aggregate of
the  denominations  of all  Certificates  of the Class to which this  Certificate  belongs) in certain  monthly
distributions  with respect to a Trust Fund  consisting  primarily of the  Mortgage  Loans  deposited by Credit

terms used  herein have the  meanings  assigned  in the  Agreement.  This  Certificate  is issued  under and is
subject to the terms,  provisions  and  conditions  of the  Agreement,  to which  Agreement  the Holder of this
Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

        No transfer of this  Certificate  shall be made unless such  transfer is made  pursuant to an effective
registration  statement  under the Securities Act and any applicable  state  securities  laws or is exempt from
the  registration  requirements  under  said Act and such laws.  In the event that a transfer  is to be made in
reliance  upon an exemption  from the  Securities  Act and such laws,  in order to assure  compliance  with the
Securities   Act  and  such  laws,   the   Certificateholder   desiring  to  effect  such   transfer  and  such
Certificateholder's  prospective  transferee shall each certify to the Trust Administrator in writing the facts
surrounding  the transfer  and (i) deliver a letter in  substantially  the form of either  Exhibit L and either
(A) Exhibit M-1,  provided that all of the  Certificates  of the Class shall be  transferred to one investor or
the Depositor  otherwise consents to such transfer,  or (B) Exhibit M-2 or (ii) there shall be delivered to the
Trust  Administrator  at the expense of the  transferor  an Opinion of Counsel  that such  transfer may be made
pursuant to an exemption from the  Securities  Act. The Holder hereof  desiring to effect such transfer  shall,
and does hereby  agree to,  indemnify  the  Trustee,  the Trust  Administrator  and the  Depositor  against any
liability  that may result if the transfer is not so exempt or is not made in accordance  with such federal and
state laws.

        Pursuant to Section 6.02(f) of the Agreement,  no transfer of an ERISA-Restricted  Certificate shall be
made unless the Trustee  shall have received  either (i) a  representation  letter from the  transferee of such
ERISA-Restricted   Certificate,   acceptable  to  and  in  form  and  substance   satisfactory   to  the  Trust
Administrator,  to the effect that such  transferee is not an employee  benefit plan or arrangement  subject to
Section 406  of  ERISA or  Section 4975  of the  Code,  or a  person  using  the  assets  of any  such  plan or
arrangement  which  representation  letter shall not be an expense of the Trustee,  the Trust  Administrator or
the Trust Fund,  (ii) if the purchaser is an insurance  company and the  ERISA-Restricted  Certificate has been
the subject of an  ERISA-Qualifying  Underwriting,  a representation that the purchaser is an insurance company
which is purchasing such Certificates  with funds contained in an "insurance  company general account" (as such
term is defined in  Section V(e) of Prohibited  Transaction  Class Exemption 95-60 ("PTCE 95-60")) and that the
purchase and holding of such  Certificate  are covered  under  Sections I and III of PTCE 95-60 or (iii) in the
case of any such  ERISA-Restricted  Certificate  presented for  registration in the name of an employee benefit
plan subject to ERISA or Section 4975 of the Code (or comparable provisions of any subsequent  enactments),  or
a person  using  such  plan's  or  arrangement's  assets,  an  Opinion  of  Counsel  satisfactory  to the Trust
Administrator  to the effect that the  purchase or holding of such  Certificate  will not result in  prohibited
transactions  under  Section 406 of ERISA and/or  Section 4975  of the Code and will not subject the Depositor,
the Trustee, the Trust  Administrator,  the Master Servicer or any other Servicer to any obligation in addition
to those  undertaken  in this  Agreement,  which  Opinion of Counsel shall not be an expense of such parties or
the Trust Fund.  In the event the  representations  referred to in the  preceding  sentence are not  furnished,
such  representation  shall be deemed to have been made to the  Trustee by the  transferee's  acceptance  of an
ERISA-Restricted  Certificate  or by any  beneficial  owner who  purchases an interest in this  certificate  in
book-entry  form.  In  the  event  that  a  representation   is  violated,   or  any  attempt  to  transfer  an
ERISA-Restricted  Certificate  to a plan or  arrangement  or person using a plan's or  arrangement's  assets is
attempted  without  the  delivery  to the  Trustee of the Opinion of Counsel  described  above,  the  attempted
transfer or acquisition of this certificate shall be void and of no effect.

        Reference  is hereby  made to the  further  provisions  of this  Certificate  set forth  following  the
signature  page hereof,  which further  provisions  shall for all purposes have the same effect as if set forth
at this place.

        This  Certificate  shall not be entitled to any benefit under the Agreement or be valid for any purpose
unless manually countersigned by an authorized signatory of the Trust Administrator.

        On any Distribution  Date on which the Stated  Principal  Balance of Mortgage Loans in such Loan Groups
as are specified in the Agreement are less than those  percentages  set forth in the  Agreement,  all remaining
Mortgage  Loans in such Loan  Groups  and all  property  acquired  in  respect  of such  Mortgage  Loans may be
purchased  as provided  in the  Agreement.  In the event that no such  purchase  occurs,  the  obligations  and
responsibilities  created by the Agreement will  terminate upon the later of the maturity or other  liquidation
(or  any  advance  with  respect  thereto)  of the  last  Mortgage  Loan  remaining  in the  Trust  Fund or the
disposition  of all  property in respect  thereof and the  distribution  to  Certificateholders  of all amounts
required to be  distributed  pursuant to the  Agreement.  In no event,  however,  will the trust created by the
Agreement  continue  beyond the earlier of (i) the  expiration  of 21 years from the death of the last survivor
of the  descendants  living at the date of the Agreement of a certain person named in the Agreement or (ii) the
Distribution  Date following the third  anniversary of the scheduled  maturity date of the Mortgage Loan having
the latest  scheduled  maturity date as of the related  Cut-off  Date.  Any term used herein that is defined in
the  Agreement  shall  have the  meaning  assigned  in the  Agreement,  and  nothing  herein  shall  be  deemed
inconsistent with that meaning.

        IN WITNESS WHEREOF, the Trust Administrator has caused this Certificate to be duly executed.

Section 406  of  ERISA or  Section 4975  of the  Code,  or a  person  using  the  assets  of any  such  plan or
arrangement  which  representation  letter shall not be an expense of the Trustee,  the Trust  Administrator or
the Trust Fund,  (ii) if the purchaser is an insurance  company and the  ERISA-Restricted  Certificate has been
the subject of an  ERISA-Qualifying  Underwriting,  a representation that the purchaser is an insurance company
which is purchasing such Certificates  with funds contained in an "insurance  company general account" (as such
term is defined in  Section V(e) of Prohibited  Transaction  Class Exemption 95-60 ("PTCE 95-60")) and that the
purchase and holding of such  Certificate  are covered  under  Sections I and III of PTCE 95-60 or (iii) in the
case of any such  ERISA-Restricted  Certificate  presented for  registration in the name of an employee benefit
plan subject to ERISA or Section 4975 of the Code (or comparable provisions of any subsequent  enactments),  or
a person  using  such  plan's  or  arrangement's  assets,  an  Opinion  of  Counsel  satisfactory  to the Trust
Administrator  to the effect that the  purchase or holding of such  Certificate  will not result in  prohibited
transactions  under  Section 406 of ERISA and/or  Section 4975  of the Code and will not subject the Depositor,
the Trustee, the Trust  Administrator,  the Master Servicer or any other Servicer to any obligation in addition
to those  undertaken  in this  Agreement,  which  Opinion of Counsel shall not be an expense of such parties or
the Trust Fund.  In the event the  representations  referred to in the  preceding  sentence are not  furnished,
such  representation  shall be deemed to have been made to the  Trustee by the  transferee's  acceptance  of an
ERISA-Restricted  Certificate  or by any  beneficial  owner who  purchases an interest in this  certificate  in
book-entry  form.  In  the  event  that  a  representation   is  violated,   or  any  attempt  to  transfer  an
ERISA-Restricted  Certificate  to a plan or  arrangement  or person using a plan's or  arrangement's  assets is
attempted  without  the  delivery  to the  Trustee of the Opinion of Counsel  described  above,  the  attempted
transfer or acquisition of this certificate shall be void and of no effect.

        Reference  is hereby  made to the  further  provisions  of this  Certificate  set forth on the  reverse
hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

        This  Certificate  shall not be entitled to any benefit under the Agreement or be valid for any purpose
unless manually countersigned by an authorized signatory of the Trust Administrator.

        On any Distribution  Date on which the Stated  Principal  Balance of Mortgage Loans in such Loan Groups
as are specified in the Agreement are less than those  percentages  set forth in the  Agreement,  all remaining
Mortgage  Loans in such Loan  Groups  and all  property  acquired  in  respect  of such  Mortgage  Loans may be
purchased  as provided  in the  Agreement.  In the event that no such  purchase  occurs,  the  obligations  and
responsibilities  created by the Agreement will  terminate upon the later of the maturity or other  liquidation
(or  any  advance  with  respect  thereto)  of the  last  Mortgage  Loan  remaining  in the  Trust  Fund or the
disposition  of all  property in respect  thereof and the  distribution  to  Certificateholders  of all amounts
required to be  distributed  pursuant to the  Agreement.  In no event,  however,  will the trust created by the
Agreement  continue  beyond the earlier of (i) the  expiration  of 21 years from the death of the last survivor
of the  descendants  living at the date of the Agreement of a certain person named in the Agreement or (ii) the
Distribution  Date following the third  anniversary of the scheduled  maturity date of the Mortgage Loan having
the latest  scheduled  maturity date as of the related  Cut-off  Date.  Any term used herein that is defined in
the  Agreement  shall  have the  meaning  assigned  in the  Agreement,  and  nothing  herein  shall  be  deemed
inconsistent with that meaning.

        IN WITNESS WHEREOF, the Trust Administrator has caused this Certificate to be duly executed.

                                             Class [__]-[__]-[__]

a beneficial ownership interest in the Trust Fund created by the Agreement.

        The  Certificateholder,  by its acceptance of this Certificate,  agrees that it will look solely to the
funds on deposit in the  Certificate  Account for payment  hereunder and that neither the Trustee nor the Trust
Administrator  is liable to the  Certificateholders  for any  amount  payable  under  this  Certificate  or the
Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

        This  Certificate  does not purport to summarize  the  Agreement and reference is made to the Agreement
for the interests,  rights and limitations of rights,  benefits,  obligations and duties evidenced thereby, and
the rights, duties and immunities of the Trustee and the Trust Administrator.

        Pursuant to the terms of the Agreement,  a distribution will be made on the 25th day of each month, or,
if such 25th day is not a Business  Day, the Business Day  immediately  following  (the  "Distribution  Date"),
commencing  on the first  Distribution  Date  specified  on the face  hereof,  to the Person in whose name this
Certificate  is  registered  at the close of business on the  applicable  Record Date in an amount equal to the
product of the Percentage  Interest  evidenced by this Certificate and the amount required to be distributed to
Holders of Certificates of the Class to which this Certificate  belongs on such  Distribution  Date pursuant to
the Agreement.  The Record Date applicable to each  Distribution  Date is (1) with  respect to all Certificates
other than the LIBOR  Certificates held in Book-Entry Form on such Distribution  Date, the close of business on
the last day of the calendar  month  preceding  the month in which such  Distribution  Date occurs and (2) with
respect to the LIBOR  Certificates held in Book-Entry Form on such Distribution  Date, the close of business on

        Distributions on this Certificate shall be made by wire transfer of immediately  available funds to the
account  of the  Holder  hereof at a bank or other  entity  having  appropriate  facilities  therefor,  if such
Certificateholder  shall have so notified the Trust  Administrator in writing at least five Business Days prior
to the related  Record Date and such  Certificateholder  shall  satisfy the  conditions to receive such form of
payment  set forth in the  Agreement,  or, if not,  by check  mailed by first class mail to the address of such
Certificateholder  appearing in the Certificate  Register.  The final  distribution on each Certificate will be
made in like manner,  but only upon  presentment  and  surrender of such  Certificate  at the  Corporate  Trust
Office or such other location specified in the notice to Certificateholders of such final distribution.

        The  Agreement  permits,  with certain  exceptions  therein  provided,  the  amendment  thereof and the
modification  of the rights and  obligations  of the  Trustee,  the Trust  Administrator  and the rights of the
Certificateholders  under the Agreement at any time by the Depositor,  the Master Servicer, the Servicers,  the
Special  Servicer,  the  Seller,  the Trustee  and the Trust  Administrator  with the consent of the Holders of
Certificates  affected by such  amendment  evidencing  the requisite  Percentage  Interest,  as provided in the
Agreement.  Any such consent by the Holder of this  Certificate  shall be conclusive and binding on such Holder
and upon all future Holders of this  Certificate and of any  Certificate  issued upon the transfer hereof or in
exchange  therefor or in lieu hereof  whether or not  notation of such  consent is made upon this  Certificate.
The Agreement also permits the amendment  thereof,  in certain  limited  circumstances,  without the consent of
the Holders of any of the Certificates.

        As provided in the  Agreement  and subject to certain  limitations  therein set forth,  the transfer of
this Certificate is registrable in the Certificate  Register of the Trust  Administrator upon surrender of this
Certificate for  registration  of transfer at the Corporate Trust Office or the office or agency  maintained by

Class in authorized  denominations  and  evidencing the same  aggregate  Percentage  Interest in the Trust Fund
will be issued to the designated transferee or transferees.

        The  Certificates  are  issuable  only as  registered  Certificates  without  coupons in  denominations
specified  in the  Agreement.  As provided in the  Agreement  and  subject to certain  limitations  therein set
forth,  Certificates are exchangeable  for new Certificates of the same Class in authorized  denominations  and
evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

        No service  charge  will be made for any such  registration  of  transfer  or  exchange,  but the Trust
Administrator  may require  payment of a sum sufficient to cover any tax or other  governmental  charge payable
in connection therewith.

        The Depositor,  each Servicer, the Master Servicer, the Seller, the Trustee and the Trust Administrator
and any agent of the  Depositor,  each  Servicer,  the Master  Servicer,  the Seller,  the Trustee or the Trust
Administrator  may treat the Person in whose name this  Certificate  is  registered as the owner hereof for all
purposes,  and none of the Depositor,  the Servicers,  the Master Servicer,  the Seller, the Trustee, the Trust
Administrator or any such agent shall be affected by any notice to the contrary.

Mortgage  Loans in such Loan  Groups  and all  property  acquired  in  respect  of such  Mortgage  Loans may be

of the  descendants  living at the date of the Agreement of a certain person named in the Agreement or (ii) the
Distribution  Date following the third  anniversary of the scheduled  maturity date of the Mortgage Loan having

---------------------------------------------------------------------------------------------------------------
Calculation of Realized Loss

Purpose

To provide the Servicer with a form for the calculation of any Realized Loss (or gain) as a result of a
Mortgage Loan having been foreclosed and Liquidated.

Distribution

The Servicer will prepare the form in duplicate and send the original together with evidence of conveyance of
title and appropriate supporting documentation to the Master Servicer with the Monthly Accounting Reports
which supports the Mortgage Loan's removal from the Mortgage Loan Activity Report.  The Servicer will retain
the duplicate for its own records.

Due Date

With respect to any liquidated Mortgage Loan, the form will be submitted to the Master Servicer no later than
the date on which statements are due to the Master Servicer under Section 4.06 of this Agreement (the
"Statement Date") in the month following receipt of final liquidation proceeds and supporting documentation
relating to such liquidated Mortgage Loan; provided, that if such Statement Date is not at least 30 days
after receipt of final liquidation proceeds and supporting documentation relating to such liquidated Mortgage
Loan, then the form will be submitted on the first Statement Date occurring after the 30th day following
receipt of final liquidation proceeds and supporting documentation.

Preparation Instructions
The numbers on the form correspond with the numbers listed below.
1.      The actual Unpaid Principal Balance of the Mortgage Loan.
2.      The Total Interest Due less the aggregate amount of servicing fee that would have been earned if all
        delinquent payments had been made as agreed.
3-7.    Complete as necessary.  All line entries must be supported by copies of appropriate statements,
        vouchers, receipts, canceled checks, etc., to document the expense.  Entries not properly documented
        will not be reimbursed to the Servicer.
8.      Accrued Servicing Fees based upon the Scheduled Principal Balance of the Mortgage Loan as calculated
        on a monthly basis.
10.     The total of lines 1 through 9.

Credits

11-17.  Complete as necessary.  All line entries must be supported by copies of the appropriate claims forms,
        statements, payment checks, etc.  to document the credit.  If the Mortgage Loan is subject to a
        Bankruptcy Deficiency, the difference between the Unpaid Principal Balance of the Note prior to the
        Bankruptcy Deficiency and the Unpaid Principal Balance as reduced by the Bankruptcy Deficiency should
        be input on line 16.

18.     The total of lines 11 through 17.

Total Realized Loss (or Amount of Any Gain)

19.     The total derived from subtracting line 18 from 10.  If the amount represents a realized gain, show
        the amount in parenthesis (   ).

COUNTY OF             )

               [NAME OF OFFICER], being first duly sworn, deposes and says:

               1.     That he is [Title of  Officer]  or [Name of  Owner]  (record  or  beneficial  owner  (the
"Owner") of the Class [AR/AR-L]  Certificates (the "Class [AR/AR-L]  Certificates")),  a [savings  institution]
[corporation]  duly  organized  and  existing  under  the  laws  of  [the  State  of  ]  [the  United  States],
on behalf of which he makes this affidavit and agreement.

               2.     That the Owner (i) is not and will not be a  "disqualified  organization"  as of [date of
transfer]  within the meaning of  Section 860E(e)(5)  of the  Internal  Revenue  Code of 1986,  as amended (the
"Code"),  (ii) will  endeavor to remain other than a  disqualified  organization  for so long as it retains its
ownership  interest  in  the  Class  [AR/AR-L]  Certificates,  and  (iii)  is  acquiring  the  Class  [AR/AR-L]
Certificates  for  its  own  account.  A  "Permitted  Transferee"  is any  person  other  than a  "disqualified
organization."  (For this  purpose,  a  "disqualified  organization"  means  the  United  States,  any state or
political  subdivision  thereof,  any  agency  or  instrumentality  of any  of the  foregoing  (other  than  an
instrumentality  all of the  activities  of which are  subject  to tax and,  except for the  Federal  Home Loan
Mortgage  Corporation,  a majority of whose board of directors is not selected by any such governmental entity)
or any  foreign  government,  international  organization  or any  agency or  instrumentality  of such  foreign
government or  organization,  any rural  electric or telephone  cooperative,  or any  organization  (other than
certain farmers'  cooperatives)  that is generally  exempt from federal income tax unless such  organization is
subject to the tax on unrelated business taxable income).

               3.     That the  Owner is aware  (i) of the tax that  would be  imposed  on  transfers  of Class
[AR/AR-L]  Certificates  to  disqualified  organizations  under  the  Code;  (ii) that such tax would be on the
transferor,  or, if such  transfer is through an agent (which person  includes a broker,  nominee or middleman)
for a  non-Permitted  Transferee,  on the agent;  (iii) that the person  otherwise  liable for the tax shall be
relieved of liability for the tax if the  transferee  furnishes to such person an affidavit that the transferee
is a Permitted  Transferee  and, at the time of transfer,  such person does not have actual  knowledge that the
affidavit is false;  and (iv) that the Class [AR/AR-L]  Certificates  may be "noneconomic  residual  interests"
within the meaning of  Treasury  regulations  promulgated  pursuant  to the Code and that the  transferor  of a
noneconomic  residual  interest  will  remain  liable  for any taxes  due with  respect  to the  income on such
residual  interest,  if a  significant  purpose  of the  transfer  was to enable the  transferor  to impede the
assessment or collection of tax.

               4.     That the Owner is aware of the tax  imposed  on a  "pass-through  entity"  holding  Class
[AR/AR-L]  Certificates  if at any time  during the taxable  year of the  pass-through  entity a  non-Permitted
Transferee is the record  holder of an interest in such entity.  (For this  purpose,  a "pass  through  entity"
includes a regulated  investment  company,  a real estate investment trust or common trust fund, a partnership,
trust or estate, and certain cooperatives.)

               5.     That the Owner is aware that the  Trustee  will not  register  the  Transfer of any Class
[AR/AR-L]  Certificates  unless the  transferee,  or the  transferee's  agent,  delivers to it an affidavit and
agreement,  among other things,  in  substantially  the same form as this  affidavit and  agreement.  The Owner
expressly  agrees  that it will not  consummate  any such  transfer  if it  knows or  believes  that any of the
representations contained in such affidavit and agreement are false.

               6.     That the  Owner  has  reviewed  the  restrictions  set  forth  on the  face of the  Class
[AR/AR-L]  Certificates  and the provisions of Section 6.02 of the Pooling and Servicing  Agreement under which
the Class [AR/AR-L]  Certificates  were issued.  The Owner  expressly  agrees to be bound by and to comply with
such restrictions and provisions.

               7.     That the Owner  consents to any additional  restrictions  or  arrangements  that shall be
deemed  necessary  upon  advice of counsel to  constitute  a  reasonable  arrangement  to ensure that the Class
[AR/AR-L] Certificates will only be owned, directly or indirectly, by an Owner that is a Permitted Transferee.

               8.     That the Owner's Taxpayer Identification Number is ________________.

               9.     That  the  Owner  is  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,  or an estate or trust  whose  income  from  sources  without the United
States is  includable  in gross  income  for  United  States  federal  income tax  purposes  regardless  of its
connection with the conduct of a trade or business within the United States.

               10.    That  no  purpose  of  the  Owner  relating  to  the  purchase  of  the  Class  [AR/AR-L]
Certificate by the Owner is or will be to impede the assessment or collection of tax.

               11.    That the Owner has no  present  knowledge  or  expectation  that it will be unable to pay
any United States taxes owed by it so long as any of the Certificates remain outstanding.

               12.    That the Owner has no present  knowledge or expectation  that it will become insolvent or
subject to a bankruptcy proceeding for so long as any of the Certificates remain outstanding.

               13.    That no purpose of the Owner relating to any sale of the Class  [AR/AR-L]  Certificate by
the Owner will be to impede the assessment or collection of tax.

               14.    The Owner  hereby  agrees to cooperate  with the Trustee and to take any action  required
of it by the Code or  Treasury  regulations  thereunder  (whether  now or  hereafter  promulgated)  in order to
create or maintain the REMIC status of the Trust Fund.

               15.    That the  Owner is not an  employee  benefit  or other  plan  subject  to the  prohibited
transaction  provisions  of the Employee  Retirement  Income  Security Act of 1974,  as amended  ("ERISA"),  or
Section 4975  of the  Internal  Revenue Code of 1986,  as amended (the "Code") (a "Plan"),  or any other person
(including an investment  manager, a named fiduciary or a trustee of any Plan) acting,  directly or indirectly,
on behalf of or purchasing any Certificate with "plan assets" of any Plan.

               16.    The Owner  hereby  agrees that it will not take any action that could  endanger the REMIC
status of the  Trust  Fund or  result  in the  imposition  of tax on the Trust  Fund  unless  counsel  for,  or
acceptable  to, the Trustee has  provided an opinion that such action will not result in the loss of such REMIC
status or the imposition of such tax, as applicable.

               17.    The Owner has provided financial statements or other financial  information  requested by
the  transferor  in  connection  with the transfer of the Residual  Certificates  to permit the  transferor  to
assess the financial capability of the Owner to pay any such taxes.

               IN WITNESS WHEREOF, the Owner has caused this instrument to be executed on its behalf,  pursuant
to the  authority of its Board of Directors,  by its [Title of Officer] and its  corporate  seal to be hereunto

                      Class AR (the "Certificates")

Ladies and Gentlemen:

               This letter is delivered to you in connection with the sale by _________________  (the "Seller")
to  ____________________________________  (the  "Purchaser")  of a _______%  Percentage  Interest  in the above
referenced  Certificates,  pursuant  to  Section 6.02  of the  Pooling  and  Servicing  Agreement  dated  as of
October 1,  2005,  among Credit Suisse First Boston  Mortgage  Securities  Corp.,  as  depositor,  DLJ Mortgage
Capital,  Inc.,  as a  seller,  Washington  Mutual  Bank,  as a  seller  and as a  servicer,  Select  Portfolio
Servicing,  Inc., as a servicer and as special servicer, U.S. Bank National Association,  as trustee, and Wells
Fargo Bank, N.A., as a servicer,  master servicer,  back-up servicer and trust  administrator (the "Pooling and
Servicing  Agreement").  All terms used herein and not  otherwise  defined shall have the meanings set forth in
the Pooling and Servicing  Agreement.  The Seller hereby  certifies,  represents and warrants to, and covenants
with, the Depositor and the Trustee that:

               1.     No  purpose  of the  Seller  relating  to sale of the  Certificate  by the  Seller to the
Purchaser is or will be to enable the Seller to impede the assessment or collection of any tax.

               2.     The  Seller  understands  that the  Purchaser  has  delivered  to the  Trustee a transfer
affidavit and  agreement in the form  attached to the Pooling and Servicing  Agreement as Exhibit N. The Seller
does not know or believe that any representation contained therein is false.

               3.     The  Seller has no actual  knowledge  that the  proposed  Transferee  is not a  Permitted
Transferee.

               4.     The Seller has no actual  knowledge  that the  Purchaser  would be unwilling or unable to
pay taxes due on its share of the taxable income attributable to the Certificate.

               5.     The Seller has conducted a reasonable  investigation  of the  financial  condition of the
Purchaser and, as a result of the  investigation,  found that the Purchaser has historically  paid its debts as
they came due, and found no  significant  evidence to indicate that the Purchaser  will not continue to pay its
debts as they come due in the future.

               6.     The  Purchaser  has  represented  to the Seller that,  if the  Certificate  constitutes a
noneconomic  residual  interest,  it (i) understands that as holder of a noneconomic  residual  interest it may
incur tax  liabilities  in excess of any cash flows  generated by the  interest,  and (ii) intends to pay taxes
associated with its holding of the Certificate as they become due.

                                            Very truly yours,

                                            [SELLER]

                           Representations and Warranties of DLJMC - Mortgage Loans

               DLJMC, in its capacity as Seller,  hereby makes the  representations and warranties set forth in
this Schedule III to the Depositor,  the Trustee and the Trust Administrator,  as of the Closing Date, or if so
specified herein,  as of the Cut off Date or such other date as may be specified,  with respect to the Mortgage
Loans identified on Schedule I hereto, except as specified herein.

               (i)    The  information  set forth in  Schedule  I,  with  respect  to the  Mortgage  Loans,  is
        complete, true and correct in all material respects;

               (ii)   [Reserved];

               (iii)  No Mortgage Loan will be 30 or more days  delinquent  as of the Cut-off  Date.  There are
        no material defaults under the terms of any Mortgage Loan;

               (iv)   All taxes,  governmental  assessments,  insurance  premiums,  water,  sewer and municipal
        charges,  leasehold  payments or ground rents which previously  became due and owing have been paid, or
        escrow funds have been  established  in an amount  sufficient to pay for every such escrowed item which
        remains unpaid and which has been assessed but is not yet due and payable;

               (v)    The terms of the Mortgage Note and the Mortgage have not been impaired,  waived,  altered
        or  modified  in any  respect,  except by  written  instruments  which have been  recorded  or sent for
        recording to the extent any such  recordation is required by law, or, necessary to protect the interest
        of the Depositor.  No other instrument of waiver,  alteration or modification has been executed, and no
        Mortgagor has been released,  in whole or in part,  from the terms thereof except in connection with an
        assumption  agreement  and which  assumption  agreement is part of the  Mortgage  File and the terms of
        which are reflected in Schedule IA; the substance of any such waiver,  alteration or  modification  has
        been  approved by the issuer of any related  Mortgage  Guaranty  Insurance  Policy and title  insurance
        policy, to the extent required by the related policies;

               (vi)   The Mortgage Note and the Mortgage are not subject to any right of  rescission,  set-off,
        counterclaim or defense,  including,  without limitation,  the defense of usury, nor will the operation
        of any of the terms of the Mortgage  Note or the  Mortgage,  or the  exercise of any right  thereunder,
        render the Mortgage  Note or Mortgage  unenforceable,  in whole or in part,  or subject to any right of
        rescission,  set-off,  counterclaim  or defense,  including the defense of usury,  and no such right of
        rescission, set-off, counterclaim or defense has been asserted with respect thereto;

               (vii)  All buildings or other customarily  insured  improvements upon the Mortgaged Property are
        insured by an insurer  acceptable  under the FNMA  Guides,  against  loss by fire,  hazards of extended
        coverage  and such other  hazards as are  provided  for in the FNMA Guides or by FHLMC,  as well as all
        additional requirements set forth in Section 4.10 of this Agreement.  All such standard hazard policies
        are in full force and effect  and on the date of  origination  contained  a standard  mortgagee  clause
        naming  DLJMC and its  successors  in  interest  and  assigns as loss payee and such clause is still in
        effect and all premiums due thereon have been paid. If required by the Flood  Disaster  Protection  Act
        of 1973, as amended,  the Mortgage Loan is covered by a flood insurance policy meeting the requirements
        of the current  guidelines of the Federal  Insurance  Administration  which policy conforms to FNMA and
        FHLMC  requirements,  as  well  as all  additional  requirements  set  forth  in  Section 4.10  of this
        Agreement.  Such  policy was  issued by an  insurer  acceptable  under  FNMA or FHLMC  guidelines.  The
        Mortgage obligates the Mortgagor  thereunder to maintain all such insurance at the Mortgagor's cost and
        expense,  and on the  Mortgagor's  failure to do so,  authorizes the holder of the Mortgage to maintain
        such  insurance  at the  Mortgagor's  cost and  expense  and to seek  reimbursement  therefor  from the
        Mortgagor;

               (viii) Each  Mortgage  Loan at the time it was made  complied in all material  respects with all
        applicable  local,  state  and  federal  laws,  including,  without  limitation,  usury,  equal  credit
        opportunity, disclosure, recording and all applicable predatory and abusive lending laws;

               (ix)   The related  Mortgage is a valid,  subsisting,  enforceable  and perfected  first lien on
        the Mortgaged  Property,  including for Mortgage Loans that are not Cooperative Loans, all buildings on
        the Mortgaged  Property and all installations  and mechanical,  electrical,  plumbing,  heating and air
        conditioning  systems affixed to such buildings,  and all additions,  alterations and replacements made
        at any time with respect to the foregoing  securing the Mortgage  Note's  original  principal  balance.
        The  Mortgage  and the  Mortgage  Note do not contain any  evidence of any  security  interest or other
        interest or right thereto.  Such lien is free and clear of all adverse claims,  liens and  encumbrances
        having  priority over the first lien, as  applicable,  of the Mortgage  subject only to (1) the lien of
        non-delinquent  current real property  taxes and  assessments  not yet due and payable,  (2) covenants,
        conditions and restrictions,  rights of way, easements and other matters of the public record as of the
        date of recording which are acceptable to mortgage lending institutions  generally and either (A) which
        are referred to or otherwise  considered in the appraisal made for the originator of the Mortgage Loan,
        or (B) which do not  adversely  affect the appraised  value of the  Mortgaged  Property as set forth in
        such  appraisal,  and (3) other  matters to which like  properties  are commonly  subject  which do not
        materially  interfere with the benefits of the security  intended to be provided by the Mortgage or the
        use,  enjoyment,  value or marketability of the related  Mortgaged  Property.  Any security  agreement,
        chattel  mortgage or equivalent  document related to and delivered in connection with the Mortgage Loan
        establishes  and creates a valid,  subsisting,  enforceable and perfected first lien and first priority
        security  interest on the  property  described  therein,  and the Seller has the full right to sell and
        assign the same to the Depositor;

               (x)    The  Mortgage  Note and the related  Mortgage  are  original  and genuine and each is the
        legal,  valid and binding  obligation of the maker  thereof,  enforceable in all respects in accordance
        with its terms subject to bankruptcy, insolvency, moratorium,  reorganization and other laws of general
        application affecting the rights of creditors and by general equitable principles;

               (xi)   DLJMC or its  affiliate is the sole owner of record and holder of the  Mortgage  Loan and
        the indebtedness  evidenced by the Mortgage Note.  Immediately  prior to the transfer and assignment to
        the Depositor on the Closing  Date,  the Mortgage  Loan,  including the Mortgage Note and the Mortgage,
        were not subject to an assignment  or pledge,  and DLJMC had good and  marketable  title to and was the
        sole owner thereof and had full right to transfer and sell the Mortgage Loan to the Depositor  free and
        clear of any encumbrance,  equity,  lien, pledge,  charge,  claim or security interest and has the full
        right and authority  subject to no interest or participation of, or agreement with, any other party, to
        sell and assign the Mortgage Loan and following the sale of the Mortgage  Loan,  the Depositor will own
        such Mortgage Loan free and clear of any encumbrance,  equity,  participation  interest,  lien, pledge,
        charge, claim or security interest;

               (xii)  There are no  mechanics'  or  similar  liens or claims  which  have been  filed for work,
        labor or  material  (and no rights  are  outstanding  that  under law  could  give rise to such  liens)
        affecting  the related  Mortgaged  Property  which are or may be liens prior to or equal to the lien of
        the related Mortgage;

               (xiii) All  improvements  subject to the  Mortgage  which were  considered  in  determining  the
        appraised  value of the Mortgaged  Property lie wholly within the boundaries  and building  restriction
        lines of the Mortgaged  Property  (and wholly  within the project with respect to a  condominium  unit)
        except  for de  minimis  encroachments  permitted  by the FNMA  Guide and which  have been noted on the
        appraisal or the title policy affirmatively  insures against loss or damage by reason of any violation,
        variation or encroachment adverse  circumstances which is either disclosed or would have been disclosed
        by an accurate  survey,  and no  improvements  on  adjoining  properties  encroach  upon the  Mortgaged
        Property  except those which are insured  against by the title  insurance  policy referred to in clause
        (v) above or are acceptable  under FNMA or FHLMC guidelines and all improvements on the property comply
        with all applicable zoning and subdivision laws and ordinances;

               (xiv)  The  Mortgaged   Property  is  not  subject  to  any  material  damage  by  waste,  fire,
        earthquake,  windstorm,  flood or other  casualty.  At  origination of the Mortgage Loan there was, and
        there  currently  is, no  proceeding  pending for the total or partial  condemnation  of the  Mortgaged
        Property;

               (xv)   Each  Mortgage  Loan has been  serviced  in all  material  respects  in  compliance  with
        accepted servicing practices;

               (xvi)  With respect to each Cooperative  Loan, the related Mortgage is a valid,  enforceable and
        subsisting  first security  interest on the related  Cooperative  Shares securing the related  Mortgage
        Note,  subject only to (a) liens of the Cooperative  Property for unpaid  assessments  representing the
        Mortgagor's pro rata share of the Cooperative  Property's  payments for its blanket  mortgage,  current
        and future real property taxes,  insurance  premiums,  maintenance fees and other  assessments to which
        like collateral is commonly  subject and (b) other matters to which like collateral is commonly subject
        which do not  materially  interfere  with the benefits of the  security  intended to be provided by the
        Security  Agreement.  There  are no liens  against  or  security  interest  in the  Cooperative  Shares
        relating to each  Cooperative Loan (except for unpaid  maintenance,  assessments and other amounts owed
        to the related  Cooperative  Property which  individually  or in the aggregate will not have a material
        adverse effect on such Cooperative  Loan),  which have priority over DLJMC's security  interest in such
        Cooperative Shares;

               (xvii) The  Mortgage  Loan  complies  with  all  terms,   conditions  and  requirements  of  the

        (iii) no Mortgage Loan will impose a Prepayment Premium for a term in excess of five years;

        appropriate  jurisdiction where the Mortgaged Property is located as determined by DLJMC (or in lieu of
        the original of the Mortgage or the assignment  thereof,  a duplicate or conformed copy of the Mortgage

                             CALCULATION OF REMIC I Y PRINCIPAL REDUCTION AMOUNTS

               REMIC I Y  Principal  Reduction  Amounts:  For any  Distribution  Date the  amounts by which the
Uncertificated  Principal Balances of the REMIC I Regular Interests Y-1, Y-2, Y-3 and Y-4,  respectively,  will
be reduced on such  Distribution  Date by the allocation of Realized Losses and the  distribution of principal,
determined as follows:

First,  for each of Loan Group 1, Loan Group 2, Loan Group 3 and Loan Group 4,  determine its Weighted  Average
Adjusted  Net  Mortgage  Rate  for  distributions  of  interest  that  will  be  made  on the  next  succeeding
Distribution  Date (the  "Group  Interest  Rate").  The  Principal  Reduction  Amount for each of the REMIC I Y
Certificates  will be  determined  pursuant to the  "Generic  solution  for the REMIC I Y  Principal  Reduction
Amounts" set forth below (the "Generic Solution") by making  identifications  among the actual Groups and their
related REMIC I Y and Z Regular  Interests and the Weighted  Average Adjusted Net Mortgage Rates and the Groups
named in the Generic Solution and their related REMIC I Y and Z Regular Interests as follows:

A.  Determine  which Group has the lowest Group  Interest  Rate.  That Group will be  identified  with Group AA
and the REMIC I Y and Z Regular  Interests  related  to that  Group will be  respectively  identified  with the
REMIC I Y-aa and Z-aa Regular  Interests.  The Group  Interest Rate for that Group will be identified  with J%.
If two or more  Groups  have  the  lowest  Group  Interest  Rate  pick  one for this  purpose,  subject  to the
restriction  that  each  Group  may be  picked  only once in the  course  of any such  selections  pursuant  to
paragraphs A through D of this definition.

B.  Determine  which Group has the second  lowest  Group  Interest  Rate.  That Group will be  identified  with
Group BB and the REMIC I Y and Z Regular Interests  related to that Group will be respectively  identified with
the REMIC I Y-bb and Z-bb Regular  Interests.  The Group  Interest Rate for that Group will be identified  with
K%. If two or more Groups have the second  lowest Group  Interest  Rate pick one for this  purpose,  subject to
the  restriction  that each Group may be picked  only once in the  course of any such  selections  pursuant  to
paragraphs A through D of this definition.

C.  Determine  which  Group has the third  lowest  Group  Interest  Rate.  That Group will be  identified  with
Group CC and the REMIC I Y and Z Regular Interests  related to that Group will be respectively  identified with
the REMIC I Y-cc and Z-cc Regular  Interests.  The Group  Interest Rate for that Group will be identified  with
L%. If two or more Groups have the third  lowest  Group  Interest  Rate pick one for this  purpose,  subject to
the  restriction  that each Group may be picked  only once in the  course of any such  selections  pursuant  to
paragraphs A through D of this definition.

D.  Determine  which Group has the fourth  lowest  Group  Interest  Rate.  That Group will be  identified  with
Group DD  and the  REMIC I Y and  REMIC I Z  Regular  Interests  related  to that  Group  will be  respectively
identified  with the REMIC I Y-dd and REMIC I Z-dd Regular  Interests.  The Group  Interest Rate for that Group
will be  identified  with M%. If two or more Groups have the fourth  lowest  Group  Interest  Rate pick one for
this  purpose,  subject to the  restriction  that each Group may be picked  only once in the course of any such
selections pursuant to paragraphs A through D of this definition.

The purpose of the foregoing  definitional  provisions together with the related provisions allocating Realized
Losses and defining  the Class Y and Class Z Principal  Distribution  Amounts is to  accomplish  the  following
goals in the following order of priority:

    1.  Making the ratio of Ymm to Y5 equal to γ1 after taking account of the allocation  Realized Losses
        and the  distributions  that will be made through end of the Distribution Date to which such provisions
        relate and assuring that the Principal  Reduction  Amount for each of the Class Y-aa, Class Y-bb, Class
        Y-cc, Class Y-dd, Class Z-aa, Class Z-bb,  Class Z-cc and Class Z-dd Regular  Interests is greater than
        or equal to zero for such Distribution Date;
    2.  Making the Class Y-aa  Principal  Balance less than or equal to 0.0005 of the sum of the Class Y-aa and
        Class Z-aa Principal  Balances,  the Class Y-bb  Principal  Balance less than or equal to 0.0005 of the
        sum of the Class Y-bb and Class Z-bb Principal Balances,  the Class Y-bb Principal Balance less than or
        equal to 0.0005 of the sum of the Class  Y-cc and Class  Z-cc  Principal  Balances  and the Class  Y-dd
        Principal  Balance  less than or equal to 0.0005 of the sum of the Class Y-dd and Class Z-dd  Principal
        Balances in each case after giving effect to allocations  of Realized  Losses and  distributions  to be
        made through the end of the Distribution Date to which such provisions relate; and
    3.  Making the larger of (a) the fraction  whose  numerator is Ymm and whose  denominator is the sum of Ymm
        and Class Z-dd Principal  Balance and (b) the fraction whose  numerator is Y5 and whose  denominator is
        the sum of Y5, the Class Z-aa Principal  Balance,  the Class Z-bb Principal  Balance and the Class Z-cc
        Principal Balance as large as possible while remaining less than or equal to 0.0005.

In the event of a failure of the foregoing  portion of the definition of Class Y Principal  Reduction Amount to
accomplish  both of goals 1 and 2 above,  the amounts  thereof  should be adjusted to so as to accomplish  such
goals within the  requirement  that each Class Y Principal  Reduction  Amount must be less than or equal to the
sum of (a) the principal  portion of Realized Losses to be allocated on the related  Distribution  Date for the
related  Group  remaining  after the  allocation  of such  Realized  Losses to the  related  Class P-M  Regular
Interest (if any) and (b) the  remainder of the portion of the REMIC I Available  Distribution  Amount  derived
from the related Group after reduction  thereof by the  distributions to be made on such  Distribution Date (i)
to the related Class P-M Regular  Interest (if any), (ii) to the related Class X-M Regular  Interests and (iii)
in respect of interest on the related Class Y and Class Z Regular  Interests,  or, if both of such goals cannot
be  accomplished  within such  requirement,  such adjustment as is necessary shall be made to accomplish goal 1
within such  requirement.  In the event of any conflict  among the  provisions of the definition of the Class Y
Principal  Reduction  Amounts,  such conflict shall be resolved on the basis of the goals and their  priorities
set forth above within the requirement set forth in the preceding  sentence.  If the formula  allocation of ΔY5

The purpose of the foregoing  definitional  provisions together with the related provisions allocating Realized
Losses and defining  the Class Y and Class Z Principal  Distribution  Amounts is to  accomplish  the  following
goals in the following order of priority:

    1.  Making the ratio of Y6 to Yjj equal to γ2 after taking account of the allocation  Realized Losses
        and the  distributions  that will be made through end of the Distribution Date to which such provisions
        relate and assuring that the Principal  Reduction  Amount for each of the Class Y-aa, Class Y-bb, Class
        Y-cc, Class Y-dd,  Class Z-aa, Class Z-bb, Class Z-cc and Class Z-dd Regular  Interests is greater than
        or equal to zero for such Distribution Date;
    2.  Making the Class Y-aa  Principal  Balance less than or equal to 0.0005 of the sum of the Class Y-aa and
        Class Z-aa Principal  Balances,  the Class Y-bb  Principal  Balance less than or equal to 0.0005 of the
        sum of the Class Y-bb and Class Z-bb Principal Balances,  the Class Y-bb Principal Balance less than or
        equal to 0.0005 of the sum of the Class  Y-cc and Class  Z-cc  Principal  Balances  and the Class  Y-dd
        Principal  Balance  less than or equal to 0.0005 of the sum of the Class Y-dd and Class Z-dd  Principal
        Balances in each case after giving effect to allocations  of Realized  Losses and  distributions  to be
        made through the end of the Distribution Date to which such provisions relate; and
    3.  Making the larger of (a) the fraction  whose  numerator is Yjj and whose  denominator is the sum of Yjj
        and Class Z-aa Principal  Balance and (b) the fraction whose  numerator is Y6 and whose  denominator is
        the sum of Y6, the Class Z-bb Principal  Balance,  the Class Z-cc Principal  Balance and the Class Z-dd
        Principal Balance as large as possible while remaining less than or equal to 0.0005.

In the event of a failure of the foregoing  portion of the definition of Class Y Principal  Reduction Amount to
accomplish  both of goals 1 and 2 above,  the amounts  thereof  should be adjusted to so as to accomplish  such
goals within the  requirement  that each Class Y Principal  Reduction  Amount must be less than or equal to the
sum of (a) the principal  portion of Realized Losses to be allocated on the related  Distribution  Date for the
related  Group  remaining  after the  allocation  of such  Realized  Losses to the  related  Class P-M  Regular
Interest (if any) and (b) the  remainder of the portion of the REMIC I Available  Distribution  Amount  derived
from the related Group after reduction  thereof by the  distributions to be made on such  Distribution Date (i)
to the related Class P-M Regular  Interest (if any), (ii) to the related Class X-M Regular  Interests and (iii)
in respect of interest on the related Class Y and Class Z Regular  Interests,  or, if both of such goals cannot
be  accomplished  within such  requirement,  such adjustment as is necessary shall be made to accomplish goal 1
within such  requirement.  In the event of any conflict  among the  provisions of the definition of the Class Y
Principal  Reduction  Amounts,  such conflict shall be resolved on the basis of the goals and their  priorities
set forth above within the requirement set forth in the preceding  sentence.  If the formula  allocation of ΔY6
among ΔYkk,  ΔYll and ΔYmm cannot be achieved  because either ΔYkk as so defined is greater than ΔPkk,  ΔYll as
so defined is greater than ΔPll or ΔYmm as so defined is greater than ΔPmm,  such an  allocation  shall be made
as close as possible  to the formula  allocation  within the  requirement  that  ΔYkk < ΔPkk,  ΔYll < ΔPll  and

The purpose of the foregoing  definitional  provisions together with the related provisions allocating Realized
