(22) The  Class 5-X  Certificates  will not  accrue  interest  on their  Class  Principal  Balance.  The  Class 5-X
     Certificates accrue interest on the Class 5-X Notional Amount.
(23) The Class 5-X  Certificates  will be comprised of two REMIC III  regular  interests,  a principal only 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, in each case
     reduced by any interest  shortfalls  with respect to the  Mortgage  Loans in the related Loan Group  including
     Prepayment   Interest  Shortfalls  to  the  extent  not  covered  by  Compensating   Interest  Payments.   The
     Pass-Through  Rate  for  the  Class 5-X  Certificates  or  the  REMIC III  Regular  Interest  5-X-IO  for  any
     Distribution  Date  shall  equal a per annum  rate  equal to the  percentage  equivalent  of a  fraction,  the
     numerator  of  which  is the  product  of  (a) 30  and  (b) the  sum of the  amounts  calculated  pursuant  to
     clauses (i) through  (iv) below,  and the denominator of which is the product of (a) the actual number of 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.
(24) 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.
(25) The Class P  Certificates  will not have a Class  Principal  Balance.  The Class P Certificates  shall have an
     initial  notional  balance of  $338,569,810  and will be entitled  to  distributions  of  Assigned  Prepayment
     Premiums only.  Such entitlement shall not be an interest in any REMIC created hereunder.
(26) 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.
(27) 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.

following amounts and priority:

                  (a) first,  to the REMIC II  Regular  Interests  LT1,  LT2,  LT3 and LT4, pro rata,  in an amount
equal to (A) their  Uncertificated  Accrued  Interest for such  Distribution  Date, plus (B) any amounts in respect

                           (i)      first,  to the REMIC II  Regular  Interests LT1, LT2, LT3 and LT4, pro rata, to
         the extent of any Realized Losses  allocated to such Regular  Interests on such  Distribution  Date or any
         prior  Distribution  Date and not previously  reimbursed  pursuant to this paragraph;  provided,  however,
         that  any  amounts  distributed  pursuant  to  this  paragraph  (c)(i) of  this  definition  of  "REMIC II
         Distribution  Amount" shall not cause a reduction in the  Uncertificated  Principal  Balance of any of the
         REMIC II Regular Interests LT1, LT2, LT3 and LT4; and

                           (ii)     second, to the Class AR-L  Certificates in respect of Component II thereof, any
         remaining amount.

                  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.

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

         ã0 =     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.

         ã1  =    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 =    (á/2){( ã0R1 - ã1R0)/R0R1};

         ΔY3 =    áΔP - 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 = á{ã1R0P0 - ã0R1P1}/{ã1R0};

         ΔY4 = ΔY3; and

         ΔY1 = ΔP - ΔY2 - ΔY3 - ΔY4.
         (2)      If ΔY3, as so determined, is negative, then

         ΔY3 = 0;

         ΔY2 = á{ ã0R1P1 - ã1R0P0 }/{2R1R0P1 -  ã1R0};

         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 over
the Realized Losses allocated to the REMIC II Regular Interest LT1 on such Distribution Date.

                  REMIC II  Regular Interest LT2 Principal  Distribution  Amount:  For any  Distribution  Date, the
excess,  if any, of the REMIC II Regular Interest LT2 Principal  Reduction Amount for such  Distribution  Date over
the Realized Losses allocated to the REMIC II Regular Interest LT2 on such Distribution Date.

                  REMIC II  Regular Interest LT3 Principal  Distribution  Amount:  For any  Distribution  Date, the
excess,  if any, of the REMIC II Regular Interest LT3 Principal  Reduction Amount for such  Distribution  Date over
the Realized Losses allocated to the REMIC II Regular Interest LT3 on such Distribution Date.

                  REMIC II  Regular Interest LT4 Principal  Distribution  Amount:  For any  Distribution  Date, the
excess,  if any, of the REMIC II Regular Interest LT4 Principal  Reduction Amount for such  Distribution  Date over
the Realized Losses allocated to the REMIC II Regular Interest LT4 on such Distribution Date.

                  REMIC  Provisions:  The  provisions  of the  federal  income tax law  relating  to REMICs,  which
appear at Sections 860A through 860G of the Code, and related  provisions and regulations  promulgated  thereunder,
as the foregoing may be in effect from time to time.

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

                  Residual Certificates:  As set forth in the Preliminary Statement.

                  Seller:  DLJMC.

                  Senior Certificates:  As set forth in the Preliminary Statement.

                  Senior  Liquidation   Amount:   The  Group 1  Senior  Liquidation   Amount,  the  Group 2  Senior

                  Senior  Percentage:  The Group 1 Senior  Percentage,  Group 2 Senior  Percentage,  Group 3 Senior
Percentage or Group 4 Senior Percentage, as applicable.

                  Senior  Prepayment  Percentage:  The  Senior  Prepayment  Percentage  for any  Distribution  Date
occurring during the seven years beginning on the first  Distribution  Date for each  Pass-Through  Loan Group will
equal  100%.  The  Senior  Prepayment  Percentage  for any  Distribution  Date  occurring  on or after the  seventh
anniversary  of the first  Distribution  Date for each such Loan Group  will be as  follows:  for any  Distribution
Date in the first year thereafter,  the related Senior  Percentage plus 70% of the related  Subordinate  Percentage
for  such  Distribution  Date;  for any  Distribution  Date in the  second  year  thereafter,  the  related  Senior
Percentage plus 60% of the related  Subordinate  Percentage for such  Distribution  Date; for any Distribution Date
in the third year  thereafter,  the related Senior  Percentage plus 40% of the related  Subordinate  Percentage for
such  Distribution  Date; for any Distribution  Date in the fourth year thereafter,  the related Senior  Percentage
plus 20% of the related  Subordinate  Percentage for such  Distribution  Date; and for any Distribution  Date after
the fourth year thereafter, the related Senior Percentage for such Distribution Date.

                  Notwithstanding  the foregoing,  on any Distribution  Date and with respect to each  Pass-Through
Loan  Group,  if the Senior  Percentage  exceeds the  initial  related  Senior  Percentage,  the Senior  Prepayment
Percentage for each Group for that  Distribution  Date will equal 100%,  (ii) if on or before the Distribution Date
in  February 2010,  the Class C-B  Percentage is greater than or equal to twice the Class C-B  Percentage as of the
Closing  Date,  in which case the Senior  Prepayment  Percentage  for each  Group  will  equal the  related  Senior
Percentage,  plus  50% of the  related  Subordinate  Percentage  for  that  Distribution  Date,  and if  after  the
Distribution  Date in  February 2010,  the  Class C-B  Percentage  is greater than or equal to twice the  Class C-B
Percentage  as of the  Closing  Date,  then  the  Senior  Prepayment  Percentage  for  each  such  Group  for  such
Distribution Date will equal the related Senior Percentage).

                  Notwithstanding the foregoing,  the Senior Prepayment  Percentage for any Pass-Through Loan Group
shall equal 100% for any  Distribution  Date as to which  (i) the  outstanding  principal  balance of the  Mortgage
Loans in the related Loan Group,  delinquent 60 days or more  (including  all REO  Properties and Mortgage Loans in
foreclosure)  (averaged over the preceding six month period), as a percentage of the related aggregate  Subordinate
Component Balance  as of such Distribution Date is equal to or greater than 50% or (ii) cumulative  Realized Losses
for the Mortgage  Loans in the related Loan Group exceed  (a) with  respect to any  Distribution  Date prior to the
third anniversary of the first Distribution  Date, 20% of the related aggregate  Subordinate  Component Balance  as
of the Closing Date (the "Original  Subordinate  Principal Balance"),  (b) with respect to any Distribution Date on

or after the third  anniversary  but prior to the eighth  anniversary  of the first  Distribution  Date, 30% of the
related Original  Subordinate  Principal Balance,  (c) with respect to any Distribution Date on or after the eighth
anniversary  but prior to the ninth  anniversary  of the  first  Distribution  Date,  35% of the  related  Original
Subordinate  Principal  Balance,  (d) with respect to any Distribution  Date on or after the ninth  anniversary but
prior to the tenth anniversary of the first  Distribution Date, 40% of the related Original  Subordinate  Principal
Balance,  (e) with  respect to any  Distribution  Date on or after the tenth  anniversary but prior to the eleventh
anniversary  of the first  Distribution  Date,  45% of the  related  Original  Subordinate  Principal  Balance  and
(f) with respect to any Distribution Date on or after the eleventh  anniversary of the first Distribution Date, 50%
of the Original Subordinate Principal Balance.

                  If the Senior  Prepayment  Percentage for one Loan Group equals 100% due to the  limitations  set
forth above, then the Senior Prepayment Percentage for the other Loan Groups will equal 100%.

                  (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  (upon receipt of reasonable  compensation),  (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 that 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,  or with respect to the WMMSC Serviced  Mortgage Loans,
WMMSC, shall provide,  promptly upon request therefor,  any such additional information or data (or with respect to
WMMSC,  any such additional loan level  information and data regarding the WMMSC Serviced  Mortgage Loans) 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 (other than WMMSC)
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.  WMMSC shall  indemnify  the Trustee and the Trust  Administrator
and hold each of them  harmless  for any  loss,  liability,  damage,  claim or  expense,  other  than any  special,
indirect,  punitive or  consequential  loss,  liability,  damage,  claim or  expense,  of the Trustee and the Trust
Administrator  arising  from  any  failure  of WMMSC  to  provide,  or to  cause  to be  provided,  the loan  level
information  or  data  regarding  the  WMMSC  Mortgage  Loans   reasonably   requested  by  the  Trustee  or  Trust
Administrator,  and  required to be provided by WMMSC  pursuant to this Section  2.07(m),  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.

                  As set forth in Section 2.08 of the Standard Terms.

                  SECTION 4.01.     Priorities of Distribution.

                  (I)      (A)      On each  Distribution  Date,  with  respect to the Group 1,  Group 2,  Group 3,
Group 4 and Class C-B  Certificates,  the Trust Administrator shall determine the amounts to be distributed to each
Class of Certificates as follows:

                           (a)      with  respect to the  Group 1  Certificates,  from the  Available  Distribution

                                    (i)     first, concurrently,  to the Group 1 Certificates,  an amount allocable
                  to interest equal to the related Interest  Distribution  Amount for such  Distribution  Date, any
                  shortfall  being  allocated  pro rata  between such  Classes  based on the Interest  Distribution
                  Amount that would have been distributed in the absence of such shortfall; and

                                    (ii)    second,  on each  Distribution  Date,  from the Available  Distribution
                  Amount  for  Loan  Group 1  remaining  after  giving  effect  to the  distributions  pursuant  to
                  Section 4.01(I)(A)(a)(i) above,  the Group 1 Senior Principal  Distribution Amount, as principal,
                  sequentially, as follows:

                                            (A)      first,   to   the   Class AR   Certificates   and   Class AR-L
                           Certificates,  pro rata based on their respective Class Principal  Balances  immediately
                           prior to such  Distribution  Date, until their respective Class Principal  Balances have
                           been reduced to zero; and

                                            (B)      second, the Group 1 Senior Principal  Distribution  Amount for
                           that  Distribution  Date  remaining  after making the  payments  specified in clause (A)
                           above,  to the  Class 1-A-1  and  Class 1-A-2  Certificates,  pro  rata  based  on their
                           respective Class Principal  Balances  immediately prior to such Distribution Date, until
                           their respective Class Principal Balances have been reduced to zero;

                           (b)      with respect to the Group 2 Certificates,  and from the Available  Distribution
         Amount relating to Loan Group 2:

                                    (i)     first,  to the Group 2  Certificates,  an amount  allocable to interest
                  equal to the related Interest Distribution Amount for such Distribution Date; and

                                    (ii)    second,  on each  Distribution  Date,  from the Available  Distribution
                  Amount  for  Loan  Group 2  remaining  after  giving  effect  to the  distributions  pursuant  to
                  Section 4.01(I)(A)(b)(i) above,  the Group 2 Senior Principal  Distribution Amount, as principal,
                  to the Class 2-A-1 Certificates, until its Class Principal Balance has been reduced to zero.

                           (c)      with respect to the Group 3 Certificates,  and from the Available  Distribution
         Amount relating to Loan Group 3:

                                    (i)     first, concurrently,  to the Group 3 Certificates,  an amount allocable
                  to interest equal to the related Interest  Distribution  Amount for such  Distribution  Date, any
                  shortfall  being  allocated  pro rata  between such  Classes  based on the Interest  Distribution
                  Amount that would have been distributed in the absence of such shortfall; and

                                    (ii)    second,  on each  Distribution  Date,  from the Available  Distribution
                  Amount  for  Loan  Group 3  remaining  after  giving  effect  to the  distributions  pursuant  to
                  Section 4.01(I)(A)(c)(i) above,  to the  Class 3-A-1  Certificates,  Class 3-A-2-1  Certificates,
                  Class 3-A-2-2  Certificates  and  Class 3-A-3  Certificates,  as  principal,  the Group 3  Senior
                  Principal  Distribution  Amount,  pro rata based on their  respective  Class  Principal  Balances
                  immediately  prior to such  Distribution  Date, until their  respective Class Principal  Balances
                  have been reduced to zero; provided,  however,  that the aggregate amount that would otherwise be
                  allocable to the Class 3-A-2-1  Certificates and  Class 3-A-2-2  Certificates on any Distribution
                  Date will instead be allocated in the following order of priority:

                                            (A)      first,  the lesser of (1)  $600,000  and (2) 99.80% of the pro

                  extent such amount is held by REMIC III).

                  (B)      On each  Distribution  Date,  the amount  referred to in clause (i) of the definition of
Interest Distribution Amount for such Distribution Date for each Class of Group 1,  Group 2,  Group 3,  Group 4 and
Class C-B  Certificates  shall be reduced by the Trust  Administrator  by the related Class's pro rata share (based
on the  amount  of the  Interest  Distribution  Amount  for  each  such  Class before  reduction  pursuant  to this
Section 4.01(I)(B))  of (i) Net  Prepayment  Interest  Shortfalls  for Mortgage Loans in the related Loan Group for

Group 1,  Group 2,  Group 3 and Group 4  Mortgage Loan, as applicable,  that was the subject of Special Hazard Loss
during the prior  calendar  month,  the excess of one month's  interest at the  related  Net  Mortgage  Rate on the
Stated  Principal  Balance of such  Mortgage  Loan as of the Due Date in such month over the amount of  Liquidation
Proceeds  applied as interest on such Mortgage Loan with respect to such month,  (B) after the Bankruptcy  Coverage
Termination  Date, with respect to each Group 1,  Group 2,  Group 3 or Group 4  Mortgage Loan, as applicable,  that
became  subject to a Bankruptcy  Loss during the prior  calendar  month,  the interest  portion of the related Debt
Service  Reduction or Deficient  Valuation,  (C) each  Relief Act  Reduction for any Group 1,  Group 2,  Group 3 or
Group 4  Mortgage  Loan,  as  applicable,  incurred  during the prior  calendar  month and (D) after the Fraud Loss
Coverage  Termination  Date,  with  respect  to each  Group 1,  Group 2,  Group 3  or  Group 4  Mortgage  Loan,  as
applicable,  that became a Fraud Loan  during the prior  calendar  month the excess of one month's  interest at the
related Net Mortgage  Rate on the Stated  Principal  Balance of such Mortgage Loan as of the Due Date in such month
over the amount of  Liquidation  Proceeds  applied as interest on such  Mortgage  Loan with  respect to such month.
For  purposes  of  calculating  the  reduction  of the  Interest  Distribution  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
related  Subordination  Level of such Class is less than such percentage as of the Closing Date, no 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.

                  (D)      The Trust  Administrator  shall  distribute  the  Mortgage  Loan  Purchase  Price of any
Optional  Termination  of Loan Group 1,  Loan Group 2,  Loan Group 3 and Loan Group 4 in excess of the Par Value to
the holder of the Class AR-L Certificate.

                  (II)     With respect to the Group 5 Certificates:

                           (a)      On each  Distribution  Date,  the  Trust  Administrator  shall  distribute  the

                           (b)      Notwithstanding  the distributions on the REMIC Regular Interests  described in
         this  Section 4.01(III),  distribution  of  funds  from the  Certificate  Account  shall  be made  only in
         accordance with Sections 4.01(I) and (II).

                  (IV)     On each  Distribution  Date, the Trust  Administrator  shall distribute to the Holder of

                  SECTION 4.02.     Allocation of Losses.

                  (a)      Realized  Losses on the  Mortgage  Loans in each of Loan  Group 1,  Loan  Group 2,  Loan
Group 3 and Loan Group 4  incurred  during a calendar  month shall be allocated by the Trust  Administrator  to the
Classes of 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;  with respect to the Group 3
         Certificates,  Realized  Losses on the Group 3 Loans that would  otherwise be allocated to the Class 3-A-1
         Certificates,  Class 3-A-2-1 Certificates,  Class 3-A-2-2 Certificates and Class 3-A-3 Certificates in the
         aggregate will instead be allocated  first,  to the  Class 3-A-3  Certificates,  until its Class Principal
         Balance  has  been  reduced  to  zero,  and  second,  to  the  Class 3-A-1  Certificates,   Class  3-A-2-1
         Certificates and  Class 3-A-2-2  Certificates,  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; 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 LIBOR  Certificates,  beginning  with the Class of Class M  Certificates,  then
outstanding with the lowest relative payment  priority,  in each case until the respective Class Principal  Balance
thereof  has  been  reduced  to  zero,  or if no  Class M  Certificates  are  then  outstanding,  the  Class  5-A-4
Certificates,  until its Class Principal  Balance has been reduced to zero, or if the Class A-5-4  Certificates are
no longer  outstanding,  the  remaining  Group 5  Senior  Certificates,  pro rata based on their  respective  Class
Principal  Balances,  provided,  however,  that the  aggregate  amount that would  otherwise  be  allocable  to the
Class 5-A-3-1  Certificates and Class 5-A-3-2  Certificates on any Distribution Date will instead be applied first,
to the  Class 5-A-3-2  Certificates  and  second,  to the  Class 5-A-3-1  Certificates,  in  each  case  until  the
respective  Class  Principal  Balance  thereof has been  reduced to zero.  Any Applied  Loss Amount  allocated to a

                  (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

                  Losses for each such Class; or

                           (ii)     with respect to  Recoveries  on Group 5  Mortgage  Loans,  the Class  Principal
         Balance of the LIBOR  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.

                  (b)      Any increase to the Class Principal  Balance of a Class of  Certificates  shall increase
the Certificate Balance of the related Class pro rata in accordance with each Certificate Percentage Interest.

                  SECTION 4.04.     Monthly Statements to Certificateholders.

                  As set forth in Section 4.04 of the Standard Terms.

                  SECTION 4.05.     Servicer to Cooperate.

                  As set forth in Section 4.05 of the Standard Terms.

                  SECTION 4.06.     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 4.06(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 4.07.     Group 5 Interest Rate Cap Account.

                  (a)      On the Closing Date, the Trust  Administrator  shall establish and maintain in its name,
in trust for the benefit of the Holders of the  Class 5-X  Certificates,  the Group 5  Interest  Rate Cap  Account.
The Group 5  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 March 2007 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.

                  (c)      On each  Distribution  Date on and after the Distribution  Date in March 2007 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 in the following order of priority:

                           (1)      to the Group 5 Senior Certificates,  pro rata based on the amount of any unpaid
         Current Interest and Carryforward  Interest,  to the extent not paid from the Group 5 Interest  Remittance
         Amount;

                           (2)      sequentially,  to  the  Class 5-M-1,   Class 5-M-2,  Class 5-M-3,  Class 5-M-4,
         Class 5-M-5,  Class 5-M-6,  Class 5-M-7,  Class 5-M-8,  Class 5-M-9 and Class 5-M-10 Certificates, in that
         order,  any unpaid Current  Interest and  Carryforward  Interest,  to the extent not paid from the Group 5
         Interest Remittance Amount;

                           (3)      to the Principal  Remittance  Amount,  the Net Cumulative  Realized Loss Amount
         for such Distribution Date;

                           (4)      first, to the  Class 5-A-1,  Class 5-A-2-1,  Class 5-A-2-2,  Class 5-A-3-1  and
         Class 5-A-3-2  Certificates,  any  Deferred  Amount  for such  classes,  pro rata,  weighted  based on the
         amounts due; provided,  however,  that the aggregate Deferred Amounts that would otherwise be allocable to
         the  Class 5-A-3-1  Certificates  and  Class 5-A-3-2  Certificates  in  the  aggregate,  will  instead  be

         allocated  first,  to the  Class 5-A-3-1  Certificates  until any Deferred  Amount for such Class has been
         paid in full, and then, to the Class 5-A-3-2  Certificates;  second, to the Class 5-A-4 Certificates,  any
         Deferred  Amount for such  class;  third,  sequentially,  to the  Class 5-M-1,  Class 5-M-2,  Class 5-M-3,
         Class 5-M-4,   Class 5-M-5,   Class 5-M-6,   Class 5-M-7,   Class 5-M-8,   Class 5-M-9  and   Class 5-M-10
         Certificates,  in that order,  any  Deferred  Amount for such  Classes,  in each case such amounts will be
         applied  prior to giving  effect to  amounts  available  to be paid in respect of  Deferred  Amounts  from
         Monthly Excess Cashflow;

                           (5)      to the  Group 5  Senior  Certificates,  the  amount of any  unpaid  Basis  Risk
         Shortfalls  for such Class,  pro rata,  weighted  based on the amounts due, in each case such amounts will
         be applied  prior to giving  effect to amounts  available  to be paid in respect of Basis Risk  Shortfalls
         from Monthly Excess Cashflow;

                           (6)      sequentially,  to  the  Class 5-M-1,   Class 5-M-2,  Class 5-M-3,  Class 5-M-4,
         Class 5-M-5,  Class 5-M-6,  Class 5-M-7,  Class 5-M-8,  Class 5-M-9 and Class 5-M-10 Certificates, in that
         order,  the amount of any unpaid Basis Risk  Shortfalls for such class,  in each case such amounts will be
         applied prior to giving effect to amounts  available to be paid in respect of Basis Risk  Shortfalls  from
         Monthly Excess Cashflow; and

                           (7)      to the Class 5 X Certificates.

                  (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  Date. The Trust  Administrator  shall account for the Group 5 Interest Rate Cap Account as an outside
reserve 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 4.07(d) (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 LIBOR  Certificates  equals zero, any amounts on deposit in the Group 5
Interest  Rate  Cap  Account  not  payable  on the  LIBOR  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 4.07(c) 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 4.07(c).
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 Trust  Administrator is hereby directed,  on or prior to the Closing Date, on behalf
of the Trust and not in its  individual  capacity,  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 Trust
Administrator  shall  not  individually  or  personally  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.

amounts  payable to the Servicers,  the Master  Servicer,  the Custodian,  the Trustee and the 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 11.01 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 any  Related  Pass-Through  Loan  Groups  is  less  than  5% of the  Aggregate  Related
Pass-Through  Collateral Balance for such Related  Pass-Through Loan Groups as of the 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,
the Seller 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 the  Floater  Loan Group is less than 5% of the  Aggregate  Loan Group  Balance for such
Floater Loan Group as of the 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;  provided,  however,
that the Trust  Administrator  may not solicit any such bids at any time while there are NIM Notes  related to such
Floater  Loan Group  outstanding.  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,
the Seller 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)      With  respect to the  purchase of Mortgage  Loans in any Loan  Group(s) as  described in
      Section 11.01(a), 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 related 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 related  Optional  Termination  Date and (b) SPS is a Servicer with respect
            to any such Mortgage  Loans on the related  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 related Optional  Termination  Date, if (a) DLJMC
            is not the owner of the  servicing  rights  with  respect  to any such  Mortgage  Loans on the  related
            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 any  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 related  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 (and with respect to
the purchase of the Mortgage  Loans in any Loan Group to which a Swap or a Cap relates,  the related  Counterparty)
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 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  shall 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 rights of
the owner of the  servicing  rights  related to the  Mortgage  Loans  purchased  in 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 11.04 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 related 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 the final  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 11.04 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 11.04,  the Holder of the
         related  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 the related REMIC created pursuant to this Agreement.

                  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 YAA
and ZAA  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 YBB and ZBB 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 YCC and ZCC 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 YDD and REMIC I ZDD 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.

Second,  apply the Generic Solution set forth below to determine the REMIC I Y Principal  Reduction Amounts for the
Distribution Date using the identifications made above.

                  Generic Solution for the REMIC I Y Principal  Reduction  Amounts:  For any Distribution Date, the
amounts by which the  Uncertificated  Principal  Balances of the REMIC I YAA,  YBB,  YCC and YDD Regular  Interests

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

goals in the following order of priority:

1.   Making the ratio of (Yn - ΔYn ) to (Y11 - ΔY11 ) equal to  γ1  after  taking  account of the  allocation
     Realized  Losses and the  distributions  that will be made through the end of the  Distribution  Date to which
     such  provisions  relate and assuring  that the Principal  Reduction  Amount for each of the REMIC I YAA, YBB,
     YCC,  YDD,  ZAA,  ZBB, ZCC and ZDD Regular  Interests  is greater than or equal to zero for such  Distribution
     Date;
2.   Making the REMIC I YAA  Uncertificated  Principal Balance less than or equal to 0.0005 of the sum of the REMIC
     I YAA and REMIC I ZAA Uncertificated  Principal  Balances,  the REMIC I YBB  Uncertificated  Principal Balance
     less  than or  equal  to  0.0005  of the  sum of the  REMIC I YBB  and  REMIC I ZBB  Uncertificated  Principal
     Balances,  the REMIC I YCC  Uncertificated  Principal  Balance  less than or equal to 0.0005 of the sum of the
     REMIC I YCC and  REMIC I ZCC  Uncertificated  Principal  Balances,  the REMIC I YDD  Uncertificated  Principal
     Balance  less than or equal to 0.0005 of the sum of the REMIC I YDD and REMIC I ZDD  Uncertificated  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 (Yn - ΔYn ) and whose  denominator is the sum of (Yn
     - ΔYn) and (Zn - ΔZn) and (b) the fraction  whose  numerator is (Y11 - ΔY11) and whose  denominator is the sum
     of (Y11 - ΔY11) and (Z11 - ΔZ11) 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 REMIC I 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 REMIC I Y  Principal  Reduction  Amount must be less than or equal to the sum of
(a) the Principal  Realized Losses to be allocated on the related  Distribution Date for the related Pool remaining
after the allocation of such Realized Losses to the related class of ratio-strip  principal only  certificates,  if
any, and (b) the remainder of the Available  Distribution  Amount for the related Pool or after  reduction  thereof
by the distributions to be made on such  Distribution  Date (i) to the related class of ratio-strip  principal only
certificates,  if any, (ii) to the related class of ratio-strip  interest only  certificates,  if any, and (iii) in
respect of  interest  on the  related  REMIC I Y and REMIC I Z  Certificates,  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 REMIC I 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 ΔY11 among ΔYj, ΔYk,
ΔYl and ΔYm cannot be achieved  because  one or more of ΔYj,  ΔYk,  ΔYl and ΔYm, as so defined is greater  than the
related  one of ΔPj,  ΔPk,  ΔPl and ΔPm,  such an  allocation  shall be made as close as  possible  to the  formula
allocation within the requirement that ΔYj < ΔPj, ΔYk < ΔPk, ΔYl < ΔPl, ΔYm < ΔPm and ΔYm < ΔPm.

     and whose  denominator  is the sum of (Y21 -  ΔY21)  and (Z21 - ΔZ21)  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 REMIC I 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 REMIC I Y Principal  Reduction  Amount must be less than or
         equal to the sum of (a) the Principal  Realized  Losses to be allocated on the related  Distribution  Date
         for the related Pool  remaining  after the  allocation  of such  Realized  Losses to the related  class of
         ratio-strip  principal  only  certificates,  if any, and (b) the remainder of the  Available  Distribution
         Amount  for  the  related  Pool  or  after  reduction  thereof  by the  distributions  to be  made on such
         Distribution  Date (i) to the related class of ratio-strip  principal only  certificates,  if any, (ii) to
         the related class of ratio-strip  interest only certificates,  if any, and (iii) in respect of interest on
         the related REMIC I Y and REMIC I 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 REMIC I 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
         allocations  of ΔY21  among  ΔYj,  ΔYk and ΔYl or ΔY22  among  ΔYm and
         ΔYn  cannot be achieved  because  one or more of  ΔYj,  ΔYk,  ΔYl,  ΔYm  and
         ΔYn, as so defined, is greater than the related one of ΔPj,  ΔPk,  ΔPl,  ΔPm
         and  ΔPn,  such an allocation  shall be made as close as possible to the formula  allocation  within
         the  requirement  that ΔYj < ΔPj,  ΔYk < ΔPk,  ΔYl < ΔPl,  ΔYm <
         ΔPm and ΔYn < ΔPn.

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

     1.  Making the ratio of (Y32 - ΔY32 ) to (Y31 - ΔY31 ) equal to γ3  after taking  account of
         the  allocation  Realized  Losses  and  the  distributions  that  will  be  made  through  the  end of the
         Distribution  Date to which such provisions  relate and assuring that the Principal  Reduction  Amount for
         each of the REMIC I YAA, YBB,  YCC, YDD, ZAA, ZBB, ZCC and ZDD Regular  Interests is greater than or equal
         to zero for such Distribution Date;
     2.  Making the REMIC I YAA  Uncertificated  Principal  Balance  less than or equal to 0.0005 of the sum of the
         REMIC I YAA and REMIC I ZAA Uncertificated  Principal Balances,  the REMIC I YBB Uncertificated  Principal
         Balance  less  than or  equal  to  0.0005  of the sum of the  REMIC I YBB and  REMIC I ZBB  Uncertificated
         Principal Balances,  the REMIC I YCC Uncertificated  Principal Balance less than or equal to 0.0005 of the
         sum  of  the  REMIC  I YCC  and  REMIC  I ZCC  Uncertificated  Principal  Balances  and  the  REMIC  I YDD
         Uncertificated  Principal  Balance  less than or equal to 0.0005 of the sum of the REMIC I YDD and REMIC I
         ZDD  Uncertificated  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 (Y32 -  ΔY32 ) and whose  denominator  is
         the sum of (Y32 -  ΔY32)  and (Z32 -  ΔZ32)  and (b) the  fraction  whose  numerator is (Y31 -
         ΔY31)  and whose  denominator  is the sum of (Y31 - ΔY31)  and (Z31 - ΔZ31)  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 REMIC I 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 REMIC I Y  Principal  Reduction  Amount must be less than or equal to the sum of
(a) the Principal  Realized Losses to be allocated on the related  Distribution Date for the related Pool remaining
after the allocation of such Realized Losses to the related class of ratio-strip  principal only  certificates,  if
any, and (b) the remainder of the Available  Distribution  Amount for the related Pool or after  reduction  thereof
by the distributions to be made on such  Distribution  Date (i) to the related class of ratio-strip  principal only
certificates,  if any, (ii) to the related class of ratio-strip  interest only  certificates,  if any, and (iii) in
respect of interest on the related REMIC I Y and REMIC I 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 REMIC I 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  allocations  of  ΔY31  among
ΔYj and ΔYk or ΔY32  among  ΔYl,  ΔYm and ΔYn cannot be achieved because one or
more of ΔYj,  ΔYk,  ΔYl,  ΔYm and ΔYn, as so defined, is greater than the related one
of  ΔPj,  ΔPk,  ΔPl,  ΔPm  and  ΔPn,  such an  allocation  shall  be made as close as

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

1.   Making the ratio of (Y42 -  ΔY42 ) to (Yj - ΔYj ) equal to γ4  after  taking  account of the
     allocation  Realized Losses and the  distributions  that will be made through the end of the Distribution Date
     to which such  provisions  relate and assuring  that the  Principal  Reduction  Amount for each of the REMIC I
     YAA,  YBB,  YCC,  YDD,  ZAA,  ZBB,  ZCC and ZDD Regular  Interests  is greater  than or equal to zero for such
     Distribution Date;
2.   Making the REMIC I YAA  Uncertificated  Principal Balance less than or equal to 0.0005 of the sum of the REMIC
     I YAA and REMIC I ZAA Uncertificated  Principal  Balances,  the REMIC I YBB  Uncertificated  Principal Balance
     less  than or  equal  to  0.0005  of the  sum of the  REMIC I YBB  and  REMIC I ZBB  Uncertificated  Principal
     Balances,  the REMIC I YCC  Uncertificated  Principal  Balance  less than or equal to 0.0005 of the sum of the
     REMIC I YCC and REMIC I ZCC Uncertificated  Principal  Balances and the REMIC I YDD  Uncertificated  Principal
     Balance  less than or equal to 0.0005 of the sum of the REMIC I YDD and REMIC I ZDD  Uncertificated  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 (Y42 -  ΔY42 ) and whose  denominator  is the
     sum of (Y42 - ΔY42)  and (Z42 -  ΔZ42)  and (b) the fraction  whose  numerator is (Yj - ΔYj)
     and  whose  denominator  is the sum of (Yj -  ΔYj)  and (Zj -  ΔZj)  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 REMIC I 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 REMIC I Y  Principal  Reduction  Amount must be less than or equal to the sum of
(a) the Principal  Realized Losses to be allocated on the related  Distribution Date for the related Pool remaining
after the allocation of such Realized Losses to the related class of ratio-strip  principal only  certificates,  if
any, and (b) the remainder of the Available  Distribution  Amount for the related Pool or after  reduction  thereof
by the distributions to be made on such  Distribution  Date (i) to the related class of ratio-strip  principal only
certificates,  if any, (ii) to the related class of ratio-strip  interest only  certificates,  if any, and (iii) in
respect of interest on the related REMIC I Y and REMIC I 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 REMIC I 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  ΔY42  among
ΔYk,  ΔYl,  ΔYm and  ΔYn  cannot be achieved  because one or more of ΔYk,  ΔYl,
ΔYm and  ΔYn,  as so defined,  is greater than the related one of ΔPk,  ΔPl,  ΔPm and
ΔPn,  such an allocation shall be made as close as possible to the formula  allocation within the requirement
that ΔYk < ΔPk, ΔYl < ΔPl, ΔYm < ΔPm and ΔYn < ΔPn.

NOTES:

1.       REMIC I YAA and ZAA  Regular  Interests  are  related  to Loan  Group  AA.  The sum of the  Uncertificated
Principal  Balances  for the REMIC I YAA and ZAA  Regular  Interests  is equal to the  aggregate  stated  principal
balance of the  Mortgage  Loans in Loan Group AA. REMIC I YBB and ZBB Regular  Interests  are related to Loan Group
BB. The sum of the  Uncertificated  Principal  Balances  for the REMIC I YBB and REMIC I ZBB Regular  Interests  is
equal to the  aggregate  stated  principal  balance of the  Mortgage  Loans in Loan  Group BB.  REMIC I YCC and ZCC
Regular Interests are related to Loan Group CC. The sum of the  Uncertificated  Principal  Balances for the REMIC I
YCC and ZCC Regular  Interests is equal to the aggregate  stated  principal  balance of the Mortgage  Loans in Loan
Group CC.  REMIC I YDD and ZDD  Regular  Interests  are  related to Loan  Group DD.  The sum of the  Uncertificated
Principal  Balances  for the REMIC I YDD and ZDD  Regular  Interests  is equal to the  aggregate  stated  principal
balance of the  Mortgage  Loans in Loan  Group DD.  The REMIC I Y and Z Regular  Interests  will be  principal  and
interest classes bearing interest at the pass-through rate for the related Loan Group.

2.       The Class CB  pass-through  rate is the  weighted  average of the  pass-through  rates on the REMIC I YAA,
YBB, YCC, and YDD Regular Interests.CREDIT SUISSE FIRST BOSTON MORTGAGE SECURITIES CORP.

                                                     CONVEYANCE OF MORTGAGE LOANS;
                                                    REPRESENTATIONS AND WARRANTIES

                  SECTION 2.01.     Conveyance of Trust Fund.

                  (ii)     the original of any guarantee executed in connection with the Mortgage Note (if any);

                  (vi)     for  each  Mortgage  Loan  that  was not a MERS  Mortgage  Loan at its  origination,  the  originals  of any

originator under the Security Agreement and the Assignment of Proprietary Lease;

                           (F) Copies of the filed UCC  assignments  or  amendments of the security  interest  referenced in clause (E)
above showing an unbroken  chain of title from the  originator to the Trust,  each with evidence of recording  thereof,  evidencing the

                           (G) An executed  assignment of the interest of the originator in the Security  Agreement,  the Assignment of

                           (H) For any  Cooperative  Loan that has been modified or amended,  the original  instrument  or  instruments
effecting such modification or amendment.

                  In addition,  in connection  with the  assignment of any MERS Mortgage  Loan, the related Seller agrees that it shall
cause,  at the related  Seller's  expense,  the MERS® System to indicate  that such  Mortgage  Loans have been  assigned by the related
Seller to the Trustee in accordance with this Agreement (and any Subsequent Transfer  Agreement,  if applicable) 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 related Custodian to confirm,  on
the Final  Certification of the related Custodian  whether or not such assignment has occurred.  The related Seller further agrees that
it shall  not,  and shall not  permit a Servicer  to,  and each  related  Servicer  agrees  that it shall  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.

                  Further,  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  Sub-Servicer,  when a Servicer or any  Sub-Servicer,  as the case may be,  believes it
appropriate in its best judgment to register any Mortgage Loan on the MERS® System,  or cause the removal from the  registration of any
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.  Any costs  incurred by a Servicer  pursuant to
this paragraph shall be considered a Servicing Advance and shall be reimburseable to such Servicer.

                  In the event the  Depositor  delivers to a 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 such  Custodian,  within 60 days of the Closing Date or the related  Subsequent  Transfer Date, as applicable,
an Officer's  Certificate which shall (i) identify the recorded document,  (ii) state that the recorded document has not been delivered
to such 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 related  Seller or the Depositor by the applicable  title insurer
in the case of clause  (c) above,  the  Depositor  shall  promptly  deliver  to the  related  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 related  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
such 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 such  Custodian and any Officer's  Certificates
delivered with respect thereto shall be delivered to the Trustee, the Trust Administrator and such 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 the Trust Fund and all
proceeds of the conversion,  voluntary or  involuntary,  of any portion of the Trust Fund 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 Trust  Administrator  to (i) execute the Interest Rate Cap
Agreements and Swap  Agreements,  and (ii) to ratify,  on behalf of the Trust, the terms agreed to by the Depositor with respect to the
Interest Rate Cap  Agreements  and Swap  Agreements.  The  Depositor  shall pay or cause to be paid on behalf of the Trust the payments
owed to the Counterparties as of the Closing Date pursuant to the terms of the Interest Rate Cap Agreements and Swap Agreements.

                  (f)      Upon one  Business  Day's  prior  written  notice to the  Trustee,  the Trust  Administrator  and the Rating
Agencies,  on any Business Day designated by the Depositor during a Prefunding Period, the Depositor,  the Seller and the Trustee shall
complete,  execute and deliver a Subsequent  Transfer  Agreement so long as each Rating  Agency has provided  notice that the execution
and  delivery of such  Subsequent  Transfer  Agreement  will not result in a reduction  or  withdrawal  of the ratings  assigned to the
Certificates on the Closing Date.

                  The  transfer of  Subsequent  Mortgage  Loans and the other  property  and rights  relating  to them on a  Subsequent
Transfer Date is subject to the satisfaction of each of the following conditions:

                           (i) each Subsequent  Mortgage Loan conveyed on such Subsequent  Transfer Date satisfies the  representations
         and warranties  applicable to it under this Agreement as of the applicable  Subsequent Transfer Date; provided,  however, that
         with respect to a breach of a  representation  and warranty with respect to a Subsequent  Mortgage Loan, the obligation  under
         Section 2.03  of this Agreement of the Seller to cure,  repurchase or replace such Subsequent  Mortgage Loan shall  constitute
         the sole remedy against the Seller respecting such breach available to Certificateholders, the Depositor or the Trustee;

                           (ii) the Rating  Agencies  shall have been  provided  with an  Opinion  of  Counsel or  Opinions  of Counsel
         (dated as of the Closing Date), at the expense of the Depositor,  with respect to the  characterization of the transfer of the
         Subsequent Mortgage Loans conveyed on such Subsequent Transfer Date as a sale;

                           (iii) the  execution  and  delivery of such  Subsequent  Transfer  Agreement  or  conveyance  of the related
         Subsequent  Mortgage  Loans does not result in a reduction or withdrawal of any ratings  assigned to the  Certificates  on the
         Closing Date by the Rating Agencies;

                           (iv)  no  Subsequent  Mortgage  Loan  conveyed  on  such  Subsequent  Transfer  Date  was  30 or  more  days
         contractually delinquent as of its subsequent Cut-off Date;

                           (v)   the remaining term to stated maturity of such Subsequent Mortgage Loan will not exceed 30 years;

                           (vi) the Depositor  shall have  deposited in the  Collection  Account all  principal and interest  collected
         with respect to the related Subsequent Mortgage Loans on or after the related Subsequent Cut-off Date;

                           (xii)   such Subsequent Mortgage Loan will be otherwise acceptable to the Rating Agencies;

                           (xiii) no Subsequent  Mortgage Loan will be subject to the  Homeownership  and Equity Protection Act of 1994
         or any comparable state or local law;

                           (xiv)    no such Subsequent Mortgage Loan will be a balloon loan;

                           (xv)     such  Subsequent  Mortgage Loan will satisfy the criteria set forth in  Section 2.01(f)(xv)  of the
         Series Supplement; and

                           (xvi)  following the  conveyance of the  Subsequent  Mortgage  Loans on such  Subsequent  Transfer Date, the
         characteristics of the Mortgage Loans in the Prefunded Group will have the characteristics  set forth in  Section 2.01(f)(xvi)
         of the Series Supplement.

                  (g)      Upon (1) delivery to the Trustee and the Trust  Administrator  by the  Depositor of a revised  Mortgage Loan
Schedule  reflecting the Subsequent  Mortgage Loans conveyed on such  Subsequent  Transfer Date and (2) delivery to the Trustee and the
Trust Administrator by the Depositor of an Officer's  Certificate  confirming the satisfaction of each of the conditions  precedent set
forth in  Section 2.01(f),  the Trust  Administrator  shall remit to the Depositor the Aggregate  Subsequent Transfer Amount related to
the  Subsequent  Mortgage  Loans  transferred by the Depositor on such  Subsequent  Transfer Date from funds in the related  Prefunding
Account.

                  The Trustee and the Trust  Administrator shall not be required to investigate or otherwise verify compliance with the
conditions set forth in the preceding  paragraph,  except for its own receipt of documents  specified  above,  and shall be entitled to
rely on the required Officer's Certificate.

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

                  (i)      The Trustee and the Trust  Administrator  are each hereby directed,  on or prior to the Closing Date, not in
their individual  capacities but solely on behalf of the Trust, to execute and deliver each of the Designated  Servicing  Agreements in
the forms  presented to them by the  Depositor,  for the benefit of the Holders of the  Certificates.  Neither the Trust  Administrator
nor the Trustee shall be  personally  liable for the payment of any  indebtedness  or expenses of the Trust or be liable for the breach
or failure of any  obligation,  representation,  warranty or covenant  made or  undertaken by the Trust  Administrator  or Trustee,  as
applicable,  on behalf of the Trust under the  Designated  Servicing  Agreements  or any other  related  documents,  as to all of which
recourse  shall be had  solely to the assets of the Trust in  accordance  with the terms of this  Agreement.  Every  provision  of this
Agreement relating to the conduct or affecting the liability of or affording  protection to the Trust  Administrator or the Trustee, as
applicable,  shall apply to the Trust  Administrator's  and the  Trustee's  execution of each  Designated  Servicing  Agreement and the
performance of any obligations thereunder.

                  SECTION 2.02.     Acceptance by the Trustee.

                  (a)      Pursuant to the related  Custodial  Agreement,  each 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,  each  Custodian  acknowledges  that such  documents  appear regular on their face and relate to such Mortgage Loan. The
Custodians  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 the related  Custodial  Agreement,  not later than 90 days after the Closing Date,  each 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  Custodians,  and subject to the
provisions  of  Section 2.01  and any  exceptions  noted on an 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 shall hold such documents and
the other  documents  delivered to it  constituting  the Mortgage  File, and that it holds or shall 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,  a Custodian  finds any document  constituting a part of a Mortgage File which does
not  meet the  requirements  of  Section 2.01,  such  Custodian  shall  list  such as an  exception  in the  Trust  Receipt  and  Final
Certification pursuant to the related Custodial Agreement;  provided,  however, that a 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 related  Seller  shall  promptly  correct or cure such defect  within 90 days from the date it was so notified of
such  defect  and, if the related  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 related 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
related  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 related  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 related  Seller shall be obligated to
repurchase  or cure any Mortgage  Loan solely as a result of a Custodian's  failure to record such  Assignment  of Mortgage.  The Trust
Administrator  shall deliver or direct the related  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 related  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 remitted by the related  Seller to the related  Servicer  for deposit 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 related  Seller became  obligated  hereunder to repurchase or replace such Mortgage  Loan.  Upon receipt of such
remittance,  the related  Servicer shall deliver a Request for Release with respect thereto  substantially  in the form of Exhibit K to
the related  Custodian,  with copies to the Trustee and the Trust  Administrator,  and upon receipt of such  Request for  Release,  the
related  Custodian shall release the related Mortgage File held for the benefit of the  Certificateholders  to the related Seller,  and
the Trustee shall execute and deliver at the related  Seller's  direction such  instruments  of transfer or assignment  prepared by the
related Seller, in each case without recourse, as shall be necessary to transfer title from the Trustee to the related Seller.

                  If pursuant to the preceding  paragraph the related Seller  repurchases a Mortgage Loan that is a MERS Mortgage Loan,
the related  Servicer shall, at the related  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  related  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 related Seller as the beneficial holder of such Mortgage Loan.

                  (b)      The related  Custodian shall execute and deliver prior to 10:00 a.m. (New York City time) on each Subsequent
Transfer Date to the Depositor,  the Trust  Administrator and each Servicer,  a Subsequent  Certification in the form annexed hereto as
Exhibit  I.  Based on its review and  examination,  and only as to the  documents  identified  in such  Subsequent  Certification,  the
Custodian  shall  acknowledge  that such documents  appear regular on their face and relate to such  Subsequent  Mortgage Loan. None of
the Trustee,  the Trust  Administrator  or the related  Custodian  shall be under any 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.

                  Not  later  than 90 days  after the end of each  Prefunding  Period,  the  related  Custodian  shall  deliver  to the
Depositor,  the Trust  Administrator,  the Seller and each  Servicer  a Final  Certification  with  respect to the  related  Subsequent
Mortgage Loans in the form annexed hereto as Exhibit J with any applicable exceptions noted thereon.

                  If, in the course of such  review of the  Mortgage  Files  relating to the  Subsequent  Mortgage  Loans,  the related
Custodian  finds any  document  constituting  a part of a Mortgage  File which does not meet the  requirements  of  Section 2.01,  such
Custodian  shall list such as an  exception in the Final  Certification;  provided,  however,  that such  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 related Seller shall
cure any such defect or repurchase or substitute for any such Mortgage Loan in accordance with Section 2.02(a).

                  (c)      It is  understood  and agreed  that the  obligation  of the  related  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 related Seller.

                  (d)      With  respect to any  Mortgage  Loan that is  delinquent  or in  default  and for which the  related  Seller
reasonably  believes breaches a representation,  warranty or covenant under the mortgage loan purchase  agreement pursuant to which the
related  Seller  purchased  from the  originator or prior holder of such Mortgage  Loan, the related Seller shall have the right to (i)
repurchase  such Mortgage Loan from the Trust at any time in order to facilitate its rights against such  originator or prior holder of
such Mortgage Loan at a price equal to the Purchase Price or (ii) substitute in its place a Qualified  Substitute  Mortgage Loan in the
manner  and  subject  to the  conditions  relating  to  substitutions  set  forth in  Section 2.03;  provided,  however,  that any such
substitution  pursuant to clause  (ii) 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 clause (ii) above shall not be
effected prior to the additional  delivery from the related Servicer to the Trustee,  the Trust Administrator and the related Custodian
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; provided,  further,  that in no event shall such repurchases or substitutions take place with
respect to Mortgage  Loans  constituting  more than 5% of the  aggregate  Cut-off Date  Principal  Balance of the  Mortgage  Loans plus
amounts on deposit in the Prefunding Accounts, if any, as of the Closing Date.

                  In the event that the  related  Seller  exercises  its option to  repurchase  a Mortgage  pursuant  to the  preceding
paragraph,  the Purchase Price for any such Mortgage Loan shall be remitted by the related  Seller to the related  Servicer for deposit
in the related  Collection  Account.  Upon receipt of such  remittance,  the related  Servicer shall deliver a Request for Release with
respect  thereto  substantially  in the  form of  Exhibit K  to the  related  Custodian,  with  copies  to the  Trustee  and the  Trust
Administrator,  and upon receipt of such Request for Release,  the related  Custodian shall release the related  Mortgage File held for
the  benefit of the  Certificateholders  to the  related  Seller,  and the Trustee  shall  execute and deliver at the related  Seller's

direction  such  instruments  of transfer or assignment  prepared by the related  Seller,  in each case without  recourse,  as shall be
necessary  to transfer  title from the Trustee to the  related  Seller.  If pursuant  to the  preceding  paragraph  the related  Seller
repurchases  a Mortgage Loan that is a MERS  Mortgage  Loan,  the related  Servicer  shall,  at the related  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 related
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 related Seller as the beneficial holder of such Mortgage Loan.

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

                  (a)      Each of DLJMC,  in its capacity as a Seller,  Wells Fargo, in its capacity as Master  Servicer,  SPS, in its
capacity as Servicer,  Special Servicer and Modification Oversight Agent, Wells Fargo, in its capacity as Servicer,  GreenPoint, in its
capacity as Servicer,  and WMMSC, in its capacity as Servicer,  in each case hereby makes the  representations and warranties set forth
in Schedules IIA, IIB, IIC, IID, IIE and IIF hereto,  respectively,  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,  Special Servicer and Modification Oversight Agent,  GreenPoint,  in
its  capacity as  Servicer,  and Wells  Fargo,  in its capacity as Servicer,  makes the  representations  and  warranties  set forth in
Schedules IIC, IID and IIE 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 2.03;  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  from the related  Servicer to the Trustee,  the Trust
Administrator  and the related  Custodian  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 2.03 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  Modification
Oversight Agent, 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 related  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
shall  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
related  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 remitted to
the related Servicer for deposit 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.  Upon receipt of such  remittance,  the related  Servicer shall deliver a Request for Release with
respect  thereto  substantially  in the  form of  Exhibit  K to the  related  Custodian,  with  copies  to the  Trustee  and the  Trust
Administrator.

                  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 remitted to the related  Servicer  for deposit 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.  Upon receipt of such  remittance of the Purchase  Price,  the related  Servicer
shall deliver a Request for Release with respect thereto  substantially in the form of Exhibit K to the related Custodian,  with copies
to the Trustee and the Trust  Administrator,  and upon receipt of such Request for Release,  the related  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 Custodians for the benefit of the Certificateholders.

                  Notwithstanding  the foregoing,  the  substitution of a Deleted Mortgage Loan or the repurchase of a Mortgage Loan by
the Seller shall be subject to, and shall in no way adversely  affect,  the rights of the owner of the servicing rights related to such
Deleted Mortgage Loan or Mortgage Loan, as applicable.

                  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 related 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  any 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 Z.

                  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,  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.

                  As set forth in Section 2.07 of the Series Supplement.

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

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

                           (i)      Such  Servicer or the Master  Servicer (to the extent it is a successor  servicer)  shall comply in
         the performance of its obligations  under this Agreement in all material  respects with all reasonable  rules and requirements
         of the insurer under each Mortgage Guaranty Insurance Policy; and

                           (ii)     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 shall contain any untrue statement of a material fact.

                  (b)      The Master  Servicer  and each  Servicer  agrees to  indemnify  the Trust Fund,  the  Depositor,  the Master
Servicer, the Trust Administrator and the Trustee for losses, damages,  penalties,  fines, forfeitures,  reasonable and necessary legal
fees and related costs,  judgments and other costs and expenses  imposed on or incurred by the Trust Fund,  the  Depositor,  the Master
Servicer,  the Trust Administrator or the Trustee, as a result of a breach of the Master Servicer's or such Servicer's,  as applicable,
covenants set forth above in  Section 2.08(a);  provided,  that the Master Servicer shall not provide  indemnification  for any damages
caused by information  provided to the Master  Servicer by any other party to this  Agreement,  any Designated  Servicer,  the Interest
Rate Cap Counterparty, the Swap Counterparty, any Custodian, any Subcontractor or any Sub-Servicer.

                                                              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 and with all  applicable  requirements  of the Servicing  Criteria,  (ii) the  Master
Servicer shall, in accordance with  Section 3.03  of this Agreement,  master service and administer the  Non-Designated  Mortgage Loans
(other than the WMMSC Serviced  Mortgage Loans) by overseeing and enforcing the servicing of the  Non-Designated  Mortgage Loans (other
than the WMMSC  Serviced  Mortgage  Loans) by the related  Servicer  (other than WMMSC)  according to the terms of this  Agreement  and
(iii) the  Master Servicer shall, in accordance with the  Section 3.20 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 GreenPoint,  SPS, Wells Fargo and
WMMSC  hereunder to service and  administer  the Mortgage Loans shall be limited to the GreenPoint  Serviced  Mortgage  Loans,  the SPS
Serviced  Mortgage Loans,  the Wells Fargo Serviced  Mortgage Loans,  and the WMMSC 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
GreenPoint  Serviced  Mortgage Loans (and the related proceeds  thereof and related REO Properties) in the case of GreenPoint,  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 and the WMMSC  Serviced
Mortgage Loans (and the related  proceeds  thereof and related REO Properties) in the case of WMMSC; 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  Mortgage  Loans shall be limited to the  GreenPoint  Serviced  Mortgage  Loans,  the SPS Serviced
Mortgage  Loans,  the Wells Fargo Serviced  Mortgage  Loans,  the Special  Serviced  Mortgage Loans and the Designated  Mortgage Loans.
Notwithstanding  anything to the contrary contained in this Agreement,  the Master Servicer shall have no obligations to master service
or administer the WMMSC 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  Sub-Servicers  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 shall 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;  provided,  however,
that the  limitations  contained in this sentence shall not apply to  modifications  made pursuant to  Section 3.05(a).  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 Mortgage Loan by any Person shall be
subject to, and shall in no way adversely affect, the rights of the owner of the servicing rights related to such Mortgage Loan.

                  With respect to each Mortgage Loan, the related  Servicer (other than WMMSC) shall fully furnish,  in accordance with
the Fair Credit  Reporting Act and its  implementing  regulations  and any other  applicable  laws,  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, to the extent that such Mortgage Loan has been serviced by such Servicer for a period of at least sixty (60) days.

                  With respect to each WMMSC  Serviced  Mortgage Loan,  WMMSC will furnish  information  regarding its borrower  credit
files to  credit  reporting  agencies  in  compliance  with  the  provisions  of the Fair  Credit  Reporting  Act and its  implementing
regulations applicable to WMMSC.

                  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 Sub-Servicer,  when a Servicer or any  Sub-Servicer,  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 Sub-Servicers.

                  (a)      The Non-Designated  Mortgage Loans may be subserviced by a Sub-Servicer on behalf of the related Servicer in
accordance with the servicing provisions of this Agreement;  provided,  that the Sub-Servicer 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 Sub-Servicer to perform any such servicing  responsibilities on its behalf, but the use by
such  Servicer of the  Sub-Servicer  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 Sub-Servicer 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  Sub-Servicer
engaged by such Servicer from its own funds.

                  A Servicer shall not permit a Sub-Servicer  to perform any servicing  responsibilities  hereunder with respect to the
Non-Designated  Mortgage Loans unless that Sub-Servicer  first agrees in writing with such Servicer to deliver an 1123 Certificate,  an
Assessment of Compliance  and an  Accountant's  Attestation  in such manner and at such times that permits that Servicer to comply with
Sections 13.06, 13.07 and 13.08 of this Agreement.

                  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  Sub-Servicer,  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.

                  A Servicer shall not outsource one or more separate servicing  functions hereunder with respect to the Non-Designated
Mortgage Loans to any Subcontractor  unless that  Subcontractor  first agrees in writing with such Servicer to deliver an Assessment of
Compliance and an Accountant's  Attestation in such manner and at such times that permits that Servicer to comply with  Sections 13.06,
13.07 and 13.08 of this Agreement.

                  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  Sub-Servicer  and arrange for any servicing  responsibilities  to be
performed  by a successor  Sub-Servicer  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 Sub-Servicer 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 Sub-Servicer  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  Sub-Servicer or a Servicer and its  Outsourcer,  or any reference  herein to actions taken through the  Sub-Servicer,
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  Sub-Servicer  and  Outsourcer  for  indemnification  of such  Servicer  by such  Sub-Servicer  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  Sub-Servicer  regardless  of whether such
payments are remitted by the Sub-Servicer to such Servicer.

                  Any  Subservicing  Agreement and any other  transactions or services  relating to the  Non-Designated  Mortgage Loans
involving a Sub-Servicer  shall be deemed to be between the  Sub-Servicer,  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  Sub-Servicer  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 Sub-Servicer'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,  GreenPoint and SPS to service and administer the Wells Fargo Serviced  Mortgage Loans,  GreenPoint  Serviced Mortgage Loans and
SPS 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 (other than WMMSC) 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  (other than
WMMSC) and shall  cause each  Servicer  (other than WMMSC) 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 each Mortgage Loan, for the related Prepayment Period, to the extent any of Wells Fargo,  GreenPoint,
SPS or the related Designated Servicer,  as applicable,  defaults in its 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  (other than WMMSC) shall for any reason no longer be a Servicer  hereunder  and the Master  Servicer  shall for any reason no
longer be Master  Servicer  hereunder  (including,  in each case, by reason of an Event of Default),  then in each case, 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);  (v) be obligated to perform any obligation of the Master Servicer or such Servicer under  Section 13.06  or  Section 13.08
with respect to any period of time during which the Trustee was not acting as the Master  Servicer or  Servicer).  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.

                  Each Servicer shall,  upon request of the Trust  Administrator,  but at the expense of such Servicer,  deliver to the
assuming  party all  documents  and records  relating to each  Subservicing  Agreement or  substitute  Subservicing  Agreement  and the
Mortgage Loans then being serviced  thereunder and hereunder by such Servicer 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 Subservicing  Agreement or substitute  Subservicing
Agreement to the assuming party.

                  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  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.

                  Consistent  with the  foregoing,  in  instances  when a  Non-Designated  Mortgage  Loan is in  default  or default is
reasonably  foreseeable  (within the meaning of the REMIC Provisions),  and if in the related Servicer's  determination,  in accordance
with Accepted  Servicing  Practices,  such modification is not materially  adverse to the interests of the  Certificateholders  (taking
into account any  estimated  Realized Loss that might result  absent such  action),  the related  Servicer may modify the terms of such
Non-Designated  Mortgage Loan to (1) capitalize to the principal  balance of such  Non-Designated  Mortgage Loan  unreimbursed  Monthly
Advances,  unreimbursed  Servicing  Advances,  unpaid Servicing Fees, and related amounts due to the related  Servicer;  (2) defer such
amounts to a balloon  payment due on the final payment date of such  Non-Designated  Mortgage Loan; (3) extend the maturity of any such
Non-Designated  Mortgage Loan, but in no instance past the date on which the final payment is due on the latest maturing  Mortgage Loan
in the related Loan Group as of the Initial  Cut-off Date;  (4) reduce the related  Mortgage Rate  (provided  that the Mortgage Rate of
any fixed-rate  Mortgage Loan may not be reduced,  and the Mortgage Rate of any adjustable  rate Mortgage Loan may not be reduced below
the Mortgage Rate of such Mortgage Loan  immediately  prior to the related first  adjustment  date);  and/or  (5) accept  less than the
outstanding  principal balance as satisfaction of such Mortgage Loan; provided,  however, that the related Servicer shall be obligated,
if so directed by the  Modification  Oversight Agent (who shall notify the Master  Servicer when it directs a Servicer),  to obtain the
consent of the Modification Oversight Agent prior to taking such action, unless such action is required by applicable law.

                  To the  extent a Servicer  is  required  to obtain  the  consent of the  Modification  Oversight  Agent  prior to any
modification,  it shall submit to the Modification  Oversight Agent any information the Modification  Oversight Agent requires, in such
form as the  Modification  Oversight  Agent shall  reasonably  request,  or in such form as may be mutually  agreed upon  between  such
Servicer and the Modification Oversight Agent, with respect to each Mortgage Loan subject to a proposed modification.

                  The Modification  Oversight Agent  acknowledges that it may, in the course of performing its  responsibilities  under
this Agreement,  be exposed to or acquire  information  concerning the Mortgage Loans and the related  Mortgagors that may be furnished
orally,  electronically or in writing by the related Servicer,  for the purpose of reviewing the modification of a Mortgage Loan, which
information  constitutes  "nonpublic  personal  information"  within  the  meaning  of the  Gramm-Leach-Biley  Act of  1999;  nonpublic
financial,  business,  scientific,  and  technical  information  of such  Servicer  (including  but not  limited  to  patterns,  plans,
compilations,  program devices,  formulas,  designs,  methods,  techniques,  processes,  procedures,  programs),  which  information is
proprietary or confidential to the Servicer  (collectively,  "Confidential  Information").  The Modification  Oversight Agent agrees to
hold the  Confidential  Information in strict  confidence and not use any  Confidential  Information of any Servicer  (i) other than in
connection with its obligations  under this Agreement;  (ii) for its own benefit;  (iii) for the benefit of any third party; or (iv) to
such  Servicer's  detriment.  The  Modification  Oversight  Agent may  disclose  Confidential  Information  to its  employees or agents
(collectively,  "Representatives")  who have a need to know such  information in connection  with the  performance of the  Modification
Oversight  Agent's  obligations  under this  Agreement,  provided that the  Modification  Oversight  Agent advises its  Representatives
exposed to such Confidential Information of their obligation to keep such information confidential.

                  (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 [Name of Series
Trust]" or, if established and maintained by a Sub-Servicer on behalf of a Servicer,  "[Sub-Servicer's  name], in trust for [Servicer's
name]" or  "[Sub-Servicer'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

Sub-Servicer  employs a  Sub-Servicer,  the Collection  Account shall be titled "[name of  Sub-Servicer's  sub-servicer],  in trust for
[Sub-Servicer'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 (other than an account  established by WMMSC) shall either be invested in Eligible  Investments or at
all times be fully insured to the full extent  permitted under  applicable law.  Notwithstanding  the foregoing,  one of the Collection
Accounts established by WMMSC shall be an Investment Account.

                  (c)      Each Servicer shall deposit in the applicable  Collection Account on a daily basis, within two Business Days
of receipt,  unless otherwise indicated,  and retain therein, the following  collections remitted by Sub-Servicers 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)(ix) 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 3.05.  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)      pursuant to  Section 3.08(a)(ix), the  aggregate amount remitted by each Servicer of Non-Designated
         Mortgage  Loans to the Trust  Administrator  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
         losses on Eligible Investments;

                           (iii)    all  Compensating  Interest  Payments  remitted by the Master  Servicer to the Trust  Administrator
         pursuant to Section 3.03 and Section 3.20(c);

                           (iv)     all Advances  remitted by the Master Servicer to the Trust  Administrator  pursuant to Section 5.01
         and Section 3.20(b); and

                           (v)      any other  amounts  deposited  hereunder  which are  required to be  deposited  in the  Certificate
         Account.

                  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, a Prefunding Account, a Capitalized  Interest 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 Depositor,  the Depositor or the Trust  Administrator,  respectively,  in Eligible  Investments,
which  shall  mature  not later than  (i) in the case of a  Collection  Account,  the Cash  Remittance  Date,  (ii) in  the case of the
Certificate  Account or a  Capitalized  Interest  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 and (iii) in the case
of a Prefunding  Account,  the Business Day immediately  preceding a Subsequent Transfer Date or on the Subsequent Transfer Date if the
invested funds are managed or advised by the Trust  Administrator  or its  affiliates.  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,  Prefunding  Account or
Capitalized  Interest  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 of any realized losses in the Certificate  Account incurred in any
such account in respect of any such  investments  shall  promptly be deposited by the Trust  Administrator  (from its own funds) in the
Certificate  Account.  The Depositor shall direct the Trust  Administrator in writing as to the investment of amounts in any Prefunding
Account or Capitalized  Interest Account.  In the absence of such written  direction,  all funds on deposit in a Prefunding  Account or
Capitalized  Interest  Account may be invested by the Trust  Administrator  in the Wells Fargo Advantage Prime  Investment Money Market
Fund or any  successor  fund thereto.  All income and gain net of any losses  realized from any such balances or investment of funds on
deposit in a Prefunding  Account or Capitalized  Interest Account shall be for the benefit of the Depositor and shall be remitted to it
monthly.  The amount of any net investment losses in a Prefunding  Account or Capitalized  Interest Account shall promptly be deposited
by the Depositor (from its own funds) in such Prefunding Account or Capitalized Interest Account, as applicable.

                  (f)      Each  Servicer,  other than Wells Fargo,  shall give notice to the  Trustee,  the Trust  Administrator,  the
Seller,  each Rating Agency and the  Depositor of any proposed  change of the location of the related  Collection  Account prior to any
change  thereof.  Wells Fargo shall give notice to the  Depositor  of any  proposed  change of the  location of the related  Collection
Account  prior to any change  thereof and,  upon  receipt of such notice,  the  Depositor  shall give notice to the Trustee,  the Trust
Administrator,  the  Seller  and each  Rating  Agency.  The Trust  Administrator  shall give  notice to the  Master  Servicer  and each
Servicer,  the Seller,  each Rating  Agency,  the Trustee and the Depositor of any proposed  change of the location of the  Certificate
Account prior to any change thereof.
                  (g)      The Trust Administrator shall establish and maintain, on behalf of the  Certificateholders,  each Prefunding
Account.  On the Closing Date,  the Depositor  shall remit the related  Prefunded  Amount to the Trust  Administrator  for deposit in a
Prefunding  Account.  On each  Subsequent  Transfer Date, upon  satisfaction  of the conditions for such  Subsequent  Transfer Date set
forth in Sections 2.01(f)  and (g), with respect to the related Subsequent  Transfer Agreement,  the Trust Administrator shall remit to
the  Depositor  the  applicable  Aggregate  Subsequent  Transfer  Amount as payment of the  purchase  price for the related  Subsequent
Mortgage Loans.

                  If any funds remain in a Prefunding  Account on the Distribution  Date  immediately  following the end of the related
Prefunding  Period, to the extent that they represent earnings on the amounts originally  deposited into such Prefunding  Account,  the
Trust  Administrator  shall  distribute them to the order of the Depositor.  The remaining funds,  other than any investment  earnings,
shall be transferred to the Certificate Account to be included as part of principal  distributions to the related  Certificates on such
Distribution Date.

                  (h)      The Trust Administrator shall establish and maintain, on behalf of the Certificateholders,  each Capitalized
Interest  Account.  On the Closing Date, the Depositor shall remit the Capitalized  Interest  Deposits to the Trust  Administrator  for
deposit in the related  Capitalized  Interest  Account.  On the Business  Day prior to the first three  Distribution  Dates,  the Trust
Administrator  shall transfer from the  Capitalized  Interest  Account to the  Certificate  Account an amount equal to the  Capitalized
Interest  Distributions for such Distribution Date and the Trust Administrator shall transfer from the Capitalized  Interest Account to
the Depositor, an amount equal to the Capitalized Interest Release Amount for such Distribution Date.

                  SECTION 3.06.     Establishment of and Deposits to Escrow Accounts; Permitted Withdrawals from Escrow Accounts;
                                    Payments of Taxes, Insurance and Other Charges.

                  (a)      To the extent  required by the related  Mortgage Note and not violative of  applicable  law, the  applicable
Servicer shall segregate and hold all funds  collected and received  pursuant to a  Non-Designated  Mortgage Loan  constituting  Escrow
Payments  separate  and apart  from any of its own funds and  general  assets  and shall  establish  and  maintain  one or more  Escrow
Accounts,  in the form of time  deposit  or demand  accounts,  titled  "[Servicer's  name],  as  Servicer  for [Name of Series  Trust],
Adjustable  Rate  Mortgage-Backed  Pass-Through  Certificates,  [Series  Name]," or, if established and maintained by a Sub-Servicer on
behalf of a Servicer,  "[Sub-Servicer's  name], in trust for [Servicer's  name]" or  "[Sub-Servicer's  name], as agent,  trustee and/or
bailee of taxes and insurance  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 Sub-Servicer  employs a sub-servicer,  the Escrow Accounts shall be titled
"[name of  Sub-Servicer's  sub-servicer]  in trust for  [Sub-Servicer's  name]. The Escrow Accounts shall be Eligible  Accounts.  Funds
deposited in the Escrow Account may be drawn on by the related Servicer in accordance with Section 3.06(d).

                  (b)      Each  Servicer  shall  deposit or cause to be deposited  in its Escrow  Account or Accounts on a daily basis
within two Business Days of receipt and retain therein:

                           (i)      all Escrow Payments  collected on account of the related  Non-Designated  Mortgage  Loans,  for the
         purpose of effecting timely payment of any such items as required under the terms of this Agreement; and

                           (ii)     all amounts  representing  Insurance  Proceeds which are to be applied to the restoration or repair
         of any Mortgaged Property related to a Non-Designated Mortgage Loan.

                  (c)      Each Servicer  shall make  withdrawals  from the Escrow Account only to effect such payments as are required
under this Agreement,  as set forth in Section 3.06(d).  Each Servicer shall be entitled to retain any interest paid on funds deposited
in the related Escrow Account by the  depository  institution,  other than interest on escrowed funds required by law to be paid to the
Mortgagor.  To the  extent  required  by  law,  the  applicable  Servicer  shall  pay  interest  on  escrowed  funds  to the  Mortgagor
notwithstanding that the Escrow Account may be non interest bearing or that interest paid thereon is insufficient for such purposes.

                  (d)      Withdrawals  from the Escrow  Account or Accounts  may be made or caused to be made by the related  Servicer
only:

                           (i)      to effect timely payments of ground rents,  taxes,  assessments,  water rates,  mortgage  insurance
         premiums,  condominium  charges,  fire and hazard  insurance  premiums or other items  constituting  Escrow  Payments  for the
         related Mortgage;

                           (ii)     to reimburse  such Servicer for any Servicing  Advances made by the such Servicer with respect to a
         related  Non-Designated  Mortgage  Loan,  but only from amounts  received on the related  Non-Designated  Mortgage  Loan which
         represent late collections of Escrow Payments thereunder;

                           (iii)    to refund to any Mortgagor any funds found to be in excess of the amounts  required under the terms
         of the related Non-Designated Mortgage Loan;

                           (iv)     for  transfer  to the related  Collection  Account to reduce the  principal  balance of the related
         Non-Designated Mortgage Loan in accordance with the terms of the related Mortgage and Mortgage Note;

                           (v)      for  application  to  restore  or repair of the  Mortgaged  Property  related  to a  Non-Designated
         Mortgage Loan in accordance with  the procedures outlined in Section 3.09(e);

                           (vi)     to pay to the related Servicer,  or any Mortgagor related to a Non-Designated  Mortgage Loan to the
         extent required by law, any interest paid on the funds deposited in such Escrow Account;

                           (vii)    to clear and terminate such Escrow Account on the termination of this Agreement; and

                           (viii)   to remove funds inadvertently placed in the Escrow Account by the related Servicer.

                  (e)      With respect to each  Non-Designated  Mortgage Loan, the applicable Servicer shall maintain accurate records
reflecting  the status of ground rents and taxes and any other item which may become a lien senior to the lien of the related  Mortgage
and the status of Mortgage Guaranty Insurance Policy premiums,  and fire and hazard insurance  coverage and shall obtain,  from time to
time, all bills for the payment of such charges  (including  renewal premiums) and shall effect or cause to be effected payment thereof
prior to the applicable penalty or termination date.

                  SECTION 3.07.     Access to Certain Documentation and Information Regarding the Non-Designated Mortgage Loans;
                                            Inspections.

                  (a)      The Master  Servicer and each Servicer shall afford the Depositor,  the Trustee and the Trust  Administrator
reasonable  access  to all  records  and  documentation  regarding  the  Non-Designated  Mortgage  Loans  and all  accounts,  insurance

Servicer  (other than WMMSC)  shall  afford the Master  Servicer  reasonable  access to all records  and  documentation  regarding  the
Non-Designated Mortgage Loans and all accounts,  insurance information and other matters relating to this Agreement,  such access being
afforded  without charge,  but only upon reasonable  written request and during normal business hours at the office  designated by such
Servicer.  In addition,  each Servicer (other than WMMSC) shall provide to the Special  Servicer  reasonable  access to all records and
documentation regarding the Non-Designated Mortgage Loans serviced by it that become Special Serviced Mortgage Loans.

                  (b)      Each Servicer,  separately with respect to the Non-Designated  Mortgage Loans each directly services,  shall
inspect the related  Mortgaged  Properties  as often as deemed  necessary by such Servicer in such party's sole  discretion,  to assure
itself that the value of such Mortgaged  Property is being preserved.  In addition,  if any  Non-Designated  Mortgage Loan is more than
60 days  delinquent,  such  Servicer,  as  applicable,  shall conduct  subsequent  inspections  in accordance  with Accepted  Servicing
Practices or as may be required by the primary mortgage  guaranty  insurer.  Each Servicer shall keep a written or electronic report of
each such inspection.

                  SECTION 3.08.     Permitted Withdrawals from the Collection Accounts and Certificate Account.

                  (a)      Each Servicer may from time to time make withdrawals from the related  Collection  Account for the following
purposes:

                           (i)      to pay to such  Servicer (to the extent not  previously  retained by such  Servicer)  the servicing
         compensation  to which  it is  entitled  pursuant  to  Section 3.14,  and to pay to such  Servicer,  as  additional  servicing

                           (ii)     to  reimburse  such  Servicer for  unreimbursed  Advances  made by it, such right of  reimbursement
         pursuant to this subclause  (ii) being limited to amounts received on the Non-Designated  Mortgage Loan(s) in respect of which
         any such Advance was made  (including  without  limitation,  late recoveries of payments,  Liquidation  Proceeds and Insurance
         Proceeds to the extent received by such Servicer);

                           (iii)    to reimburse such Servicer for any  Nonrecoverable  Advance  previously made or any amount expended
         pursuant to Section 3.11(a);

                           (iv)     to reimburse such Servicer for (A)  unreimbursed  Servicing  Advances or such  Servicer's  right to

         any such advance was made and (B) for unpaid Servicing Fees as provided in Section 3.11 hereof;

                           (v)      to pay to the purchaser,  with respect to each Non-Designated Mortgage Loan or property acquired in
         respect thereof that has been purchased  pursuant to  Section 2.02,  2.03 or 3.11, all amounts received thereon after the date
         of such purchase;

                           (vi)     to make any payments required to be made pursuant to Section 2.07 (g);

                           (vii)    to reimburse the Seller,  such  Servicer or the Depositor for expenses  incurred by any of them and

         therein;

                           (ix)     on  the  Cash  Remittance   Date,  to  withdraw  the  amount  required  to  make  payments  to  the
         Certificateholders  as set forth in the Series  Supplement,  in each case  applicable  to the  Non-Designated  Mortgage  Loans
         serviced by such  Servicer,  who shall  remit the  aggregate  of such  amounts to the Trust  Administrator  for deposit in the
         Certificate Account;

                           (x)      with  respect to each  Non-Designated  Mortgage  Loan  covered by a Lender Paid  Mortgage  Guaranty
         Insurance  Policy,  to effect  timely  payment  of the  related  premiums  on such  Mortgage  Guaranty  Insurance  Policy,  as
         applicable,  pursuant to  Section 3.09(c),  to the extent not deducted by such Servicer  prior to deposit into the  applicable
         Collection Account pursuant to Section 3.05(c);

                           (xi)     on or  prior  to 4:00  p.m.  (New  York  City  time) on the Cash  Remittance  Date  preceding  each
         Distribution  Date, each  applicable  Servicer shall withdraw an amount equal to the sum of all Assigned  Prepayment  Premiums
         received  during the related  Prepayment  Period  applicable to the Mortgage Loans  serviced by such Servicer,  and remit such
         amount to the Trust Administrator for deposit in the Certificate Account;

                           (xii)    to clear and terminate such  Collection  Account upon  termination  of this  Agreement  pursuant to
         Section 11.01 hereof; and

                           (xiii)   to reimburse such Servicer for any Capitalization Reimbursement Amounts not previously reimbursed.

                  Each Servicer shall keep and maintain separate accounting,  on a Non-Designated Mortgage Loan by Mortgage Loan basis,
for the purpose of justifying any withdrawal  from the related  Collection  Account  pursuant to such  subclauses  (i), (ii),  (iv) and
(v). Prior to making any  withdrawal  from a Collection  Account  pursuant to subclause  (iii) for  reimbursement  of a  Nonrecoverable
Advance,  the related Servicer shall deliver to the Trust  Administrator a certificate of a Servicing Officer  indicating the amount of
any previous  Advance or Servicing  Advance  determined by such Servicer to be a  Nonrecoverable  Advance and  identifying  the related
Non-Designated  Mortgage Loans(s),  and their respective portions of such  Nonrecoverable  Advance. In connection with the payment of a
Purchase Price, if a Servicer is not required to remit  unreimbursed  Advances and Servicing Advances as specified in the definition of
Purchase Price, such Servicer shall be deemed to have been reimbursed for such amount.

                  If a  Servicer  fails to remit to the  Master  Servicer  for  distribution  to the  Certificateholders  any  payment,
including any Advance to be made by the Servicer on a Cash  Remittance  Date (without  regard to any grace period),  the Servicer shall

one percentage point (but in no event greater than the maximum permitted by law).

                  (b)      The  Trust   Administrator   shall  withdraw  funds  from  the  Certificate  Account  for  distributions  to
Certificateholders,  in the manner specified in this Agreement (and to withhold from the amounts so withdrawn,  the amount of any taxes
that it is  authorized  to  withhold  pursuant  to  Section 2.07).  In  addition,  the Trust  Administrator  may from time to time make
withdrawals from the Certificate Account for the following purposes:

                           (i)      to pay to itself any  investment  income earned for the related  Distribution  Date,  and to pay to
         itself,  the Master  Servicer or any Custodian any other amounts to which it, the Master Servicer or any Custodian is entitled
         to reimbursement or payment under the terms of this Agreement or the Custodial Agreement;

                           (ii)     to  withdraw  and return to the Master  Servicer  or the  applicable  Servicer  for  deposit to the
         applicable Collection Account any amount deposited in the Certificate Account and not required to be deposited therein; and

                           (iii)    to clear and terminate  the  Certificate  Account upon  termination  of the  Agreement  pursuant to
         Section 11.01 hereof.

                  SECTION 3.09.     Maintenance of Hazard Insurance; Mortgage Impairment Insurance and Mortgage Guaranty Insurance
                                    Policy; Claims; Restoration of Mortgaged Property.

                  (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;  provided,
however,  that the  limitations  contained in this sentence shall not apply to  modifications  made pursuant to  Section 3.05(a).  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)      Unless  otherwise  required in accordance with applicable state and federal law relating to the cancellation
of, or collection of premiums for mortgage guaranty insurance,  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 3.10 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 related  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
shall be retained by such Servicer as additional servicing compensation.

                  SECTION 3.11.     Realization Upon Defaulted 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  shall 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  Expense  Fee Rate,  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 and/or with respect to  recoveries  obtained
following the liquidation of a Liquidated  Mortgage Loan ("Excess  Proceeds") that is a Non-Designated  Mortgage Loan shall be retained
by the related Servicer as additional servicing compensation pursuant to Section 3.14.

                  SECTION 3.12.     Trustee and Trust Administrator to Cooperate; Release of Mortgage Files.

                  Upon the payment in full of any  Non-Designated  Mortgage Loan, or the receipt by a Servicer of a  notification  that
payment in full will be  escrowed  in a manner  customary  for such  purposes,  such  Servicer  shall  immediately  notify the  related
Custodian by delivering,  or causing to be delivered a "Request for Release"  substantially  in the form of Exhibit K.  Upon receipt of
such request,  such  Custodian  shall within three  Business Days release the related  Mortgage File to the related  Servicer,  and the
Trustee shall within three Business Days of such  Servicer's  direction  execute and deliver to such Servicer the deed of  reconveyance
or release or satisfaction  of mortgage or such  instrument  releasing the lien of the Mortgage in each case provided by such Servicer,
and such Custodian  shall deliver the Mortgage Note with written  evidence of  cancellation  thereon.  Expenses  incurred in connection
with any instrument of  satisfaction  or deed of reconveyance  shall be chargeable to the related  Mortgagor.  From time to time and as
shall be appropriate  for the servicing or  foreclosure of any  Non-Designated  Mortgage Loan,  including for such purpose,  collection
under any policy of flood  insurance,  any  fidelity  bond or errors or  omissions  policy,  or for the purposes of effecting a partial
release of any Mortgaged  Property from the lien of the Mortgage or the making of any  corrections to the Mortgage Note or the Mortgage
or any of the other  documents  included in the Mortgage  File,  the related  Custodian  within three Business Days of delivery to such
Custodian of a Request for Release in the form of Exhibit K  signed by a Servicing  Officer,  release the Mortgage  File to the related
Servicer.  Subject to the further  limitations  set forth below,  the related  Servicer  shall cause the Mortgage  File or documents so
released to be returned to the related  Custodian on its behalf,  when the need therefor by such Servicer no longer 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 related  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 or otherwise  available
at law or in equity.

                  SECTION 3.13.     Documents, Records and Funds in Possession of a Servicer to be Held for the Trust.

                  Notwithstanding  any other provisions of this Agreement,  each Servicer shall transmit to the related  Custodian,  as
required by this  Agreement all documents and  instruments in respect of a  Non-Designated  Mortgage Loan coming into the possession of
the related  Servicer  from time to time  required to be  delivered to the Trustee,  or such  Custodian on its behalf,  pursuant to the
terms  hereof and shall  account  fully to the Trust  Administrator  for any funds  received by such  Servicer or which  otherwise  are
collected  by such  Servicer as  Liquidation  Proceeds  or  Insurance  Proceeds in respect of any  Non-Designated  Mortgage  Loan.  All
Mortgage Files and funds  collected or held by, or under the control of, a Servicer in respect of any  Non-Designated  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.

                  SECTION 3.14.     Servicing Fee; Indemnification of Master Servicer.

                  (a)      As compensation for its services hereunder,  each Servicer shall be entitled to withdraw from the applicable
Collection Account or to retain from interest payments on the related  Non-Designated  Mortgage Loans, the amount of its Servicing Fee,
for each  Mortgage  Loan  serviced by it, less any amounts in respect of its  Servicing  Fee, as  applicable,  payable by such Servicer
pursuant to  Section 3.05(c)(vi).  The Servicing Fee for each Servicer is limited to, and payable solely from, the interest  portion of
such Scheduled  Payments collected by such Servicer or as otherwise  provided in  Section 3.08(a).  In connection with the servicing of
any Special Serviced  Mortgage Loan, the Special  Servicer shall receive the Servicing Fee for such Special  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
Ancillary  Income and Excess Proceeds shall be retained by the related  Servicer and additional  servicing  compensation in the form of
Payoff Interest,  to the extent not required to make payments in respect of Compensating  Interest  Payments,  shall be retained by SPS
and WMMSC.  Each Servicer shall be required to pay all expenses  incurred by it in connection with its servicing  activities  hereunder
(including the payment of any expenses  incurred in connection with any  Subservicing  Agreement  entered into pursuant to Section 3.02
and the payment of any premiums for insurance  required  pursuant to Section 3.16)  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
Servicer and any director,  officer,  employee or agent of the Master Servicer 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)
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 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),  (y) the indemnity amounts payable by DLJMC or
the Trust to the Trust  Administrator  pursuant to Section 10.05  and (z) the  indemnity amounts payable by DLJMC or the Trust to Wells
Fargo, as Custodian,  pursuant to a Custodial  Agreement with Wells Fargo as Custodian,  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.

                  SECTION 3.15.     Access to Certain Documentation.

                  Upon reasonable  advance notice in writing for any review requiring  on-site access or upon reasonable notice for any
other type of access,  each Servicer shall provide to the Depositor,  the Trust  Administrator,  the Master Servicer (for all Servicers
other than WMMSC) and the Trustee certain reports and reasonable access to information and  documentation  regarding the Mortgage Loans
serviced by such Servicer  sufficient to permit any  Certificateholder  to comply with  applicable  regulations of the OTS, the FDIC or
other  regulatory  authorities  with respect to investment in the  Certificates;  provided,  that each Servicer shall be entitled to be
reimbursed  by each such  Certificateholder  for actual  expenses  incurred by such  Servicer  in  providing  such  reports and access.
Nothing in this  Section 3.15  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 3.15  or  Section 3.07  as a result of such  obligation  shall  not  constitute  a breach of this
Section 3.15  or  Section 3.07.  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.

                  SECTION 3.16.     Maintenance of Fidelity Bond and Errors and Omissions Insurance.

                  Each Servicer shall maintain with responsible  companies,  at its own expense,  a blanket Fidelity Bond and an Errors
and Omissions Insurance Policy,  with broad coverage on all officers,  employees or other persons acting in any capacity requiring such
persons to handle funds, money,  documents or papers relating to the related Mortgage Loans ("Servicer  Employees").  Any such Fidelity
Bond and Errors and  Omissions  Insurance  Policy shall be in the form of the  Mortgage  Banker's  Blanket  Bond and shall  protect and
insure the related Servicer against losses, including forgery, theft,  embezzlement,  fraud, errors and omissions and negligent acts of
such Servicer  Employees.  Such Fidelity  Bond and Errors and  Omissions  Insurance  Policy also shall protect and insure each Servicer
against losses in connection  with the release or satisfaction  of a related  Mortgage Loan without having obtained  payment in full of
the indebtedness  secured thereby.  No provision of this Section 3.16  requiring such Fidelity Bond and Errors and Omissions  Insurance
Policy shall  diminish or relieve a Servicer  from its duties and  obligations  as set forth in this  Agreement.  The minimum  coverage
under any such bond and insurance  policy shall be at least equal to the  corresponding  amounts  required by FNMA,  unless the related
Servicer has obtained a waiver of such requirement.  Upon the request of the Trust  Administrator,  the related Servicer shall cause to
be delivered to the Trust  Administrator  a  certificate  of  insurance  of the insurer and the surety  including a statement  from the
surety and the insurer that such fidelity bond and insurance  policy shall in no event be terminated or materially  modified without 30
days' prior written notice to the Trust Administrator.

                  The Master  Servicer shall maintain  insurance in such amounts  generally  acceptable for entities  serving as master
servicer.

                  SECTION 3.17.     Special Serviced Mortgage Loans; Repurchase of Certain Mortgage Loans.

                  (a)      If directed by the Special  Servicer and solely at the Special  Servicer's  option,  a Servicer,  other than
WMMSC,  (each, a  "Transferring  Servicer")  shall  transfer the servicing of any Mortgage Loan (other than a WMMSC  Serviced  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 prior to the servicing transfer date,  (ii) 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,
(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 3.17  (a). 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.

                  (b)      The Special  Servicer,  at its option,  may (but is not obligated to) purchase from the Trust Fund,  (i) any
Mortgage  Loan that is  delinquent  in payment 90 or more days or (ii) any  related  Mortgage Loan with respect to which there has been
initiated  legal  action  or  other  proceedings  for  the  foreclosure  of  the  related  Mortgaged   Property  either  judicially  or
non-judicially,  in each case, provided that the applicable Servicer has the right to transfer the related servicing rights without the
payment of any  compensation  to a  Sub-Servicer.  In the event that the Special  Servicer  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 the Special  Servicer,  and the Trustee  shall  execute and  deliver at the Special  Servicer's  direction  such
instruments  of transfer or  assignment  prepared by the Special  Servicer,  in each case  without  recourse,  as shall be necessary to
transfer title from the Trustee to the Special Servicer.  The applicable  Servicer shall be entitled to reimbursement  from the Special
Servicer for all expenses  incurred by it in  connection  with the transfer of any Mortgage  Loan to the Special  Servicer  pursuant to
this Section 3.17 (b).

                  (c)      With respect to any Mortgage  Loan, a Servicer of such  Mortgage  Loan may (but is not  obligated  to) enter
into a special servicing  agreement with an unaffiliated  Holder of a 100% Percentage  Interest of the most junior outstanding Class of
related  Subordinate  Certificates.  Any such  agreement  may  contain  provisions  whereby  such Holder may  (i) instruct  the related
Servicer to commence or delay  foreclosure  proceedings  with respect to any such  Mortgage  Loan that is  delinquent  and will contain
provisions  for the deposit of cash with such Servicer by such Holder that would be available for  distribution  to  Certificateholders
if Liquidation  Proceeds are less than they otherwise may have been had such Servicer acted in accordance  with its normal  procedures,
(ii) purchase  any such Mortgage Loan that is delinquent  from the Trust Fund  immediately  prior to the  commencement  of  foreclosure
proceedings  at a  price  equal  to the  Purchase  Price,  and/or  (iii) assume  all of the  servicing  rights  and  obligations  (as a
Sub-Servicer  on behalf of the related  Servicer)  with respect to any such Mortgage Loan that is delinquent so long as (A) such Holder
meets the requirements for a Sub-Servicer set forth in  Section 3.02(a),  (B) such Holder has a current special servicing ranking of at
least "Average" from S&P, (C) such Holder shall  subservice  such Mortgage Loan in accordance with this Agreement,  and (D) the related
Servicer has the right to transfer such servicing rights without the payment of any compensation to a Sub-Servicer.

                  SECTION 3.18.     Indemnification of the Trust Administrator, the Master Servicer and the Servicers.

                  Each Servicer (other than WMMSC) 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.

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

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

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

                  SECTION 3.19.     Notification of Adjustments.

                  With respect to each Mortgage  Loan, the related  Servicer  shall adjust the Mortgage Rate on the related  Adjustment
Date in compliance  with the  requirements  of applicable law and the related  Mortgage and 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 3.20.     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 such Designated  Servicing Agreement.  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 3.21.     Assigned Prepayment Premiums.

                  (a)      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,
(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 related Custodian and from its own records or files or (v)
the related  Mortgaged  Property has been damaged such that the current  value of the  Mortgaged  Property has been reduced by at least
half as a result of a natural  disaster or other  insured or  uninsured  peril,  and the  borrower  has elected to pay the loan in full
rather than rebuild the  Mortgaged  Property.  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  of such  Servicer  to make such  payment.  If such  Servicer  has waived all or a
portion of an Assigned  Prepayment Premium for any reason, it shall include such information,  including the reason for such waiver, in
any monthly reports it provides,  and such Servicer if other than Wells Fargo,  shall notify the Trust  Administrator,  the Seller, the
Master Servicer and the Trustee of such waiver, and if such Servicer is Wells Fargo,  Wells Fargo 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.

                  (b)      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),  GreenPoint (or any of its successors and assigns) or SPS (or any of its successors
and assigns).

                                                              ARTICLE IV

                                             PAYMENTS AND STATEMENTS TO CERTIFICATEHOLDERS

                  SECTION 4.01.     Priorities of Distribution.

                  SECTION 4.03.     Recoveries.

         As set forth in Section 4.03 of the Series Supplement.

                  SECTION 4.04.     Monthly Statements to Certificateholders.

                  (a)      Not later than each Distribution Date, the Trust  Administrator shall prepare and cause to be made available
to each  Certificateholder,  the Master Servicer,  each Servicer,  the Trustee,  the Depositor,  the Swap  Counterparty and each Rating
Agency,  a statement  setting  forth with  respect to the related  distribution:  (A) the items listed in  Exhibit T,  other than items
(vi)(a),  (vi)(b),  (vi)(c) and  (vi)(d),  (B) the  amounts on deposit in each  Prefunding  Account  (including  a breakdown of amounts
released  during the prior calendar month in respect of Aggregate  Subsequent  Transfer  Amounts) and (C) the amount on deposit in each
Capitalized Interest Account (including a breakdown of amounts released for the calendar month preceding such Distribution Date).

                  The Trust  Administrator's  responsibility for disbursing the above information to the  Certificateholders is limited
to the  availability,  timeliness and accuracy of the information  derived from the Master  Servicer and each Servicer,  which shall be
provided as required in Section 4.05.

                  On each Distribution Date, the Trust  Administrator  shall provide Bloomberg  Financial Markets,  L.P.  ("Bloomberg")
CUSIP level factors for each Class of Offered  Certificates as of such Distribution Date, using a format and media mutually  acceptable
to the Trust  Administrator  and Bloomberg.  In connection with providing the information  specified in this Section 4.04 to Bloomberg,
the Trust  Administrator  and any  director,  officer,  employee  or agent of the Trust  Administrator  shall be  indemnified  and held
harmless by DLJMC,  to the extent,  in the manner and subject to the  limitations  provided in  Section 9.05.  The Trust  Administrator
shall also make the monthly  statements to  Certificateholders  available each month to each party  referred to in  Section 4.04(a) via

the Trust Administrator's  website. The Trust Administrator's website can be accessed at  http://www.ctslink.com  or at such other site
as the Trust  Administrator  may designate  from time to time.  Persons that are unable to use the above website are entitled to have a
paper copy  mailed to them via first class mail by calling the Trust  Administrator  at  301-815-6600.  The Trust  Administrator  shall
have the right to change the way the reports referred to in this  Section 4.04 are distributed in order to make such  distribution more
convenient  and/or more accessible to the above parties and to the  Certificateholders.  The Trust  Administrator  shall provide timely
and adequate  notification to all above parties and to the  Certificateholders  regarding any such change. The Trust  Administrator may
fully rely upon and shall have no liability with respect to information provided by the Master Servicer or any Servicer.

                  (b)      Upon  request,  within  a  reasonable  period  of time  after  the  end of each  calendar  year,  the  Trust
Administrator  shall  cause to be  furnished  to each  Person  who at any time  during the  calendar  year was a  Certificateholder,  a
statement containing the information set forth in items (i)(c),  (i)(d),  (ii)(c) and (ii)(d) of Exhibit T aggregated for such calendar
year or applicable  portion  thereof  during which such Person was a  Certificateholder.  Such  obligation  of the Trust  Administrator
shall be deemed to have been  satisfied  to the  extent  that  substantially  comparable  information  shall be  provided  by the Trust
Administrator pursuant to any requirements of the Code as from time to time in effect.

                  (c)      In addition to the foregoing,  the Trust Administrator shall post an electronic file containing current loan
level data with  respect to the  Mortgage  Loans  ("Loan  Level  Data"),  on a monthly  basis,  to the  website  referred to in Section
4.04(a).  The Loan Level Data will include  fields as agreed to by the Depositor  and the Trust  Administrator  from time to time.  The
Loan Level Data will be based solely on information  provided by the  Servicers,  and the Trust  Administrator's  provision of the Loan
Level Data is subject to the availability,  timeliness and accuracy of the information  provided by the Servicers.  The Loan Level Data
will not include any personally  identifiable  information,  including but not limited to: borrower name,  borrower  address,  property
address,  borrower social  security  number,  and  originator's  loan account  number.  The Loan Level Data may include recent property
valuation  information,  including  based  on a  recent  broker's  price  opinion.  As  agreed  to  by  the  Depositor  and  the  Trust
Administrator,  the  format of the Loan  Level  Data may be  modified  at any  time,  and the  posting  of the Loan  Level  Data may be
discontinued at any time.  The Trust Administrator shall not be required to provide the Loan Level Data in paper form.

                  SECTION 4.05.     Servicer to Cooperate.

                  Each  Servicer  (other  than  WMMSC and SPS)  shall  provide to the Master  Servicer,  the  information  set forth in
Exhibits H-1,  H-2 and H-3 and any other information the Master Servicer  requires,  and SPS shall provide to the Master Servicer,  the
information set forth in Exhibits H-1, H-2, P and Q and any other information the Master Servicer  requires,  in each case in such form
as the Master Servicer shall  reasonably  request,  or in such form as may be mutually agreed upon between such Servicer and the Master
Servicer,  with respect to each Mortgage Loan serviced by such Servicer no later than (i) with  respect to a Servicer  other than Wells
Fargo,  12:00 noon  (New York City time) on the Data  Remittance  Date, and (ii) with  respect to Wells Fargo,  on the Data  Remittance
Date, to enable the Master Servicer to provide such information to the Trust Administrator.

                  Each  Servicer  (other  than  WMMSC)  also  shall  provide  to the  Master  Servicer,  the  information  set forth in
Exhibit H-1,  solely  relating to Payoffs  received  during the related  Prepayment  Period,  in such form as the Master Servicer shall
reasonably  request,  or in such form as may be mutually  agreed upon between such  Servicer and the Master  Servicer,  with respect to
each Mortgage  Loan  serviced by such Servicer no later than the  Additional  Data  Remittance  Date, to enable the Master  Servicer to
provide such information to the Trust Administrator.

                  The Master Servicer,  with respect to the Mortgage Loans which are not WMMSC Serviced Mortgage Loans, and WMMSC, with
respect to the WMMSC Serviced Mortgage Loans, shall provide to the Trust  Administrator the information set forth in Exhibits H-1,  H-2
and H-3 in such form as the Trust  Administrator  shall reasonably request no later than 12:00 noon (New York City time) on the related
Data Remittance Date or on the related Additional Data Remittance Date, as applicable,  to enable the Trust  Administrator to calculate
the  amounts to be  distributed  to each Class of  Certificates  and  otherwise  perform its  distribution,  accounting  and  reporting
requirements hereunder.

                  SECTION 4.06.     Cross-Collateralization; Adjustments to Available Funds.

                  SECTION 4.09.     Rights of Swap Counterparty.

                  The Swap Counterparty,  if any, shall be deemed a third-party  beneficiary of this Agreement to the same extent as if

the provisions of this Section, the Swap Counterparty shall be entitled to relief as can be given either at law or in equity.

                                                               ARTICLE V

                                             ADVANCES BY THE MASTER SERVICER AND SERVICERS

                  SECTION 5.01.     Advances by the Trust Administrator, 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  shall not be required to advance the related  balloon  payment but shall 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 (a) for each  Servicer
other than WMMSC,  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) and  (b) for  WMMSC,  one month's  interest on the
outstanding  principal  balance at the applicable  Mortgage Rate, in each case to the extent the related  Servicer deems such amount to
be  recoverable.  Each  Servicer's  obligation to make such  Advances as to any related  Non-Designated  Mortgage  Loan shall  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  (other than
WMMSC) 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 WMMSC  Serviced  Mortgage  Loan,  if the amount of Advances  received from
WMMSC is less than the amount  required to be advanced by WMMSC,  the Trust  Administrator  shall be  obligated to make a payment in an
amount equal to such deficiency,  subject to any  determination by the Trust  Administrator  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 3.20(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 of the Series Supplement.

                  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,  (B) Exhibit M-2
(the "Rule 144A  Letter") or (C) Exhibit M-3  (the "Regulation S  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)  or Regulation S,  as applicable,  for transfer of any such Certificate  without
registration  thereof  under the 1933 Act pursuant to the  registration  exemption  provided by Rule 144A  or  Regulation S.  The Trust
Administrator  shall  cooperate  with the  Depositor in providing the  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,  the Special  Servicer and the  Modification  Oversight Agent 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,  Exhibit M-2 or  Exhibit M-3,  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  if such  Certificate is a Book-Entry  Certificate.  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 Residual 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 shall
              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 6.02(g)(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.

                  (i)      Each Holder of a Swap  Certificate  or any  interest  therein  shall be deemed to have  represented,  by its
acquisition  or  holding  of such  certificate  or any  interest  therein,  that as of any date  prior to the  termination  of the Swap
Agreement,  at least one of PTCE 84-14,  90-1,  91-38,  95-60 or 96-23 or other applicable  exemption applies to such Holder's right to
receive payments from the Supplemental Interest Trust.

                  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  shall  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  shall 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.

                                                              ARTICLE VII

                                                 THE DEPOSITOR, THE SELLER, THE MASTER
                          SERVICER, THE SERVICERS, THE SPECIAL SERVICER AND THE MODIFICATION OVERSIGHT AGENT

                                    and the Modification Oversight Agent.

                  The Depositor,  the Seller, the Master Servicer,  each Servicer,  the Special Servicer and the Modification Oversight
Agent shall be liable under this Agreement to any other party to this  Agreement,  including the liability of each Servicer (other than
WMMSC) to the Master Servicer in accordance herewith only to the extent of the obligations  specifically and respectively  imposed upon
and undertaken by them herein.

                  SECTION 7.02.     Merger or Consolidation of the Seller, the Depositor, the Master Servicer, the Servicers, the
                                    Special Servicer or the Modification Oversight Agent.

                  Subject to the immediately succeeding paragraph,  the Depositor,  the Seller, the Master Servicer, each Servicer, the
Special  Servicer and the  Modification  Oversight Agent shall 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 shall  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,  any Servicer,  the Special  Servicer or the
Modification  Oversight Agent may be merged or  consolidated,  or any Person  resulting from any merger or  consolidation  to which the
Depositor,  the Seller, the Master Servicer,  any Servicer,  the Special Servicer or the Modification Oversight Agent shall be a party,
or any Person succeeding to the business of the Depositor,  the Seller, the Master Servicer,  any Servicer, the Special Servicer or the

Servicer or the  Modification  Oversight  Agent,  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
(i) the  successor or surviving  Person to the Master  Servicer,  any such Servicer (other than WMMSC) or the Special Servicer shall be
qualified to sell mortgage  loans to, and to service  mortgage loans on behalf of, FNMA or FHLMC,  and (ii) the  successor or surviving
Person to WMMSC shall have a net worth of at least $15,000,000,  unless each of the Rating Agencies acknowledge,  at the expense of the
successor or surviving  person to WMMSC,  that its rating of the Certificates in effect  immediately  prior to such assignment will not
be qualified or reduced as a result of such successor or surviving Person to WMMSC not having a net worth of at least $15,000,000.

                  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  service  the
Mortgage Loans and (b) such  purchaser or transferee  executes and delivers to the Depositor,  the 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 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 or such Servicer shall be released from its  obligations  under this
Agreement  (except as provided above),  except that the Master Servicer or the related Servicer shall remain liable for all liabilities
and  obligations  incurred by it as the Master  Servicer or Servicer  hereunder  prior to the  satisfaction  of the  conditions to such
assignment and delegation set forth in the preceding sentence.

                  SECTION 7.03.     Limitation on Liability of the Seller, the Depositor, the Master Servicer, the Servicers, the
                                    Special Servicer, the Modification Oversight Agent and Others.

                  (a)      None  of the  Depositor,  the  Master  Servicer,  any  Servicer,  the  Seller,  the  Special  Servicer,  the
Modification  Oversight  Agent,  or any of the directors,  officers,  employees or agents of the Depositor,  the Master  Servicer,  any
Servicer,  the Seller, the Special Servicer or the Modification  Oversight Agent 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, any Servicer, the Seller, the
Special  Servicer or the Modification  Oversight Agent against any breach of  representations,  warranties or covenants  (including any
indemnification  obligations provided in Section 2.08) made by it herein or protect the Depositor,  the Master Servicer,  any Servicer,
the Seller,  the  Special  Servicer or the  Modification  Oversight  Agent or any such  director,  officer,  employee or agent from any
liability  which would  otherwise be imposed by reasons of willful  misfeasance,  bad faith or gross  negligence in the  performance of
duties or by reason of reckless disregard of obligations and duties hereunder.

                  The Depositor,  the Master Servicer,  any Servicer,  the Seller, the Special Servicer and the Modification  Oversight
Agent and any director,  officer,  employee or agent of the  Depositor,  the Master  Servicer,  any Servicer,  the Seller,  the Special
Servicer or the  Modification  Oversight  Agent may rely in good faith on any  document of any kind prima facie  properly  executed and
submitted by any Person respecting any matters arising hereunder.  The Depositor,  the Master Servicer,  any Servicer,  the Seller, the
Special  Servicer and the  Modification  Oversight  Agent and any director,  officer,  employee or agent of the  Depositor,  the Master
Servicer,  any Servicer,  the Seller,  the Special Servicer or the Modification  Oversight Agent shall be indemnified by the Trust Fund

the Certificates,  other than any loss, liability or expense incurred by reason of willful  misfeasance,  bad faith or gross negligence
in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder.

                  None of the Depositor,  the Master  Servicer,  any Servicer,  the Seller,  the Special  Servicer or the  Modification
Oversight  Agent  shall be under any  obligation  to appear in,  prosecute  or defend any legal  action that is not  incidental  to its
respective  duties hereunder and which in its opinion may involve it in any expense or liability;  provided,  however,  that any of the
Depositor,  the Master  Servicer,  any  Servicer,  the Seller,  the Special  Servicer or the  Modification  Oversight  Agent 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  Certificateholders  hereunder.  In such event, the
legal expenses and costs of such action and any liability  resulting  therefrom  shall be expenses,  costs and liabilities of the Trust
Fund, and the Depositor,  the Master Servicer,  any Servicer, the Seller, the Special Servicer and the Modification Oversight Agent, as
applicable,  shall be  entitled  to be  reimbursed  therefor  from the Trust  Fund.  The right of each  Servicer  and the  Modification
Oversight  Agent to indemnity and  reimbursement  pursuant to this Section 7.03 shall survive the  resignation  or  termination of such
Servicer as set forth herein.

                  (b)      Each Servicer and the Special  Servicer  shall  indemnify the Trust  Administrator  and the Trustee and hold
them harmless against any and all claims,  losses,  damages,  penalties,  fines,  forfeitures,  reasonable and necessary legal fees and
related costs,  judgments,  and any other costs,  fees and expenses that the Trust  Administrator or the Trustee may sustain in any way
related to the failure of such Servicer or Special  Servicer to perform its duties and service the Mortgage  Loans in  compliance  with
the terms of this  Agreement.  The related  Servicer  or the Special  Servicer,  as  applicable,  shall  notify  immediately  the Trust
Administrator  and the Trustee if a claim is made by a third party with respect to this Agreement or the Mortgage  Loans,  assume (with
the prior  written  consent of the Trust  Administrator)  the defense of any such claim and pay all expenses in  connection  therewith,
including  counsel  fees,  and promptly pay,  discharge  and satisfy any judgment or decree which may be entered  against it, the Trust
Administrator or the Trustee in respect of such claim. The related Servicer or the Special  Servicer,  as applicable,  shall follow any
written  instructions  received from the Trust  Administrator in connection with such claim.  Except as otherwise  provided herein, the
Trust  Administrator  promptly shall reimburse such Servicer or the Special Servicer,  as applicable,  for all amounts advanced by such
entity  pursuant to the second  preceding  sentence  except when the claim is in any way related to the failure of such Servicer or the
Special Servicer to service and administer the Mortgage Loans in compliance with the terms of this Agreement.

                  SECTION 7.04.     Master Servicer, Servicers, Special Servicer and Modification Oversight Agent Not to Resign;
                                    Transfer of Servicing.

                  (a)      None of the Master Servicer,  any Servicer,  the Special Servicer or the Modification  Oversight Agent shall
resign from the obligations  and duties hereby imposed on it except  (i) upon  appointment of a successor  master  servicer,  successor
servicer,  successor special servicer or successor  modification oversight agent 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,  a
Servicer,  the  Special  Servicer  or the  Modification  Oversight  Agent  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,  successor  servicer,  successor  special  servicer or successor  modification  oversight agent shall have assumed the Master
Servicer's,  such Servicer's,  the Special Servicer's or the Modification Oversight Agent's, as applicable,  responsibilities,  duties,
liabilities and obligations hereunder.

                  (b)      Notwithstanding  the  foregoing,  at DLJMC's  request,  so long as it is the owner of the related  servicing
rights,  the Master  Servicer or any Servicer  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.  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
(other than the WMMSC Serviced 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.

                  (e)      Notwithstanding the foregoing,  at DLJMC's request, the Modification  Oversight Agent shall resign, upon the
selection and appointment of a successor  modification  oversight  agent 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, Special Servicer, Modification Oversight Agent and Servicers May Own
                                    Certificates.

                  Each of the Master Servicer,  the Seller, the Special Servicer, the Modification Oversight Agent 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, the Modification Oversight Agent or a Servicer.

                                                                DEFAULT

                  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

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 90 days after the date on which written  notice  thereof shall have been
given to the Master Servicer or the related Servicer by the Trust  Administrator  for the benefit of the  Certificateholders  or by the
Depositor; or

                  (d)      a decree or order of a court or agency or supervisory  authority having jurisdiction in the premises for the
appointment of a conservator or receiver or liquidator in any insolvency,  readjustment of debt,  marshalling of assets and liabilities
or similar proceedings,  or for the winding-up or liquidation of its affairs,  shall have been entered against the Master Servicer or a
Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; or

                  (e)      the Master  Servicer  or a Servicer  shall  consent to the  appointment  of a  conservator  or  receiver  or
liquidator in any  insolvency,  readjustment of debt,  marshalling of assets and  liabilities or similar  proceedings of or relating to
the Master Servicer or such Servicer or all or substantially all of the property of the Master Servicer or such Servicer; or

                  (f)      the Master  Servicer or a Servicer  shall admit in writing its inability to pay its debts  generally as they
become due, file a petition to take  advantage of, or commence a voluntary  case under,  any  applicable  insolvency or  reorganization
statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

                  (g)      any failure of the Master  Servicer or a Servicer to make any Advance in the manner and at the time required
to be made from its own funds  pursuant  to  Section 5.01  of this  Agreement  and  after  receipt  of  written  notice  from the Trust
Administrator of such failure,  which failure continues  unremedied  (i) with respect to the Master Servicer or a Servicer,  other than
WMMSC or Wells Fargo (in its capacity as a Servicer),  after 5:00 p.m.  (New York City time) on the Business Day immediately  following
the Master Servicer's or such Servicer's receipt of such notice,  (ii) with respect to Wells Fargo (in its capacity as a Servicer),  on
the second  Business Day immediately  following  Wells Fargo's receipt of such notice and (iii) with respect to WMMSC,  after 2:00 p.m.
(New York City time) on the Business Day immediately following WMMSC's receipt of such notice; or

                  (h)      either  (a) the  servicer  rankings or ratings for a Servicer  (other than WMMSC) are  downgraded  to "below
average"  status by one or more of the Rating  Agencies  rating the  Certificates  or (b) one or more Classes of the  Certificates  are
downgraded or placed on negative watch due in whole or in part to the performance or servicing of a Servicer (other than WMMSC); or

                  (i)      the servicer  rankings or ratings for a Servicer  (other than WMMSC) 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

Master  Servicer  rankings or ratings for the Master  Servicer,  are downgraded to "below  average" status by one or more of the Rating
Agencies  rating the  Certificates  or (b) one or more Classes of the  Certificates  are  downgraded or placed on negative watch due in
whole or in part to the performance or master servicing of the Master Servicer; or

                  (k)      any failure by an applicable  Servicer to either (a) remit payment of an Assigned  Prepayment Premium to the
Collection Account or (b) remit funds in the amount equal to an Assigned  Prepayment  Premium which the applicable  Servicer has failed
to collect,  in each case as required pursuant to this Agreement,  which failure continues  unremedied for a period of one Business Day
after the date upon which written notice of such 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; or

                  (l)      any  failure by the  Modification  Oversight  Agent,  the Master  Servicer  or a Servicer to comply with the
provisions of Article XIII.

                  If an Event of Default  due to the actions or inaction  of the Master  Servicer  or a Servicer  described  in clauses
(a) through  (f)  and (l) of this  Section 8.01  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 DLJMC, 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),  (ii) the  Master  Servicer  may, if such Event of Default is due to the actions or inactions of a Servicer  (other than
WMMSC),  by notice in writing to such Servicer  (with a copy to the Rating  Agencies),  terminate all of the rights and  obligations of
such  Servicer  (other than WMMSC)  under this  Agreement  (other than rights to  reimbursement  for Advances  and  Servicing  Advances
previously made, as provided in  Section 3.08)  and (iii) the Trust  Administrator  may, if such Event of Default is due to the actions
or  inactions  of  WMMSC,  by notice in  writing  to WMMSC  (with a copy to the  Rating  Agencies),  terminate  all of the  rights  and
obligations of WMMSC 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,  (ii) if WMMSC has failed to make any Advance,  the Trust  Administrator,  and (iii) if any Servicer (other than
WMMSC) 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 described in clause (h), (i) or (k) occurs,  (i) if the Event of Default relates to WMMSC, 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  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 (j) 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  (in the case of WMMSC),  or the Master  Servicer (in the case of any Servicer  other than
WMMSC) 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 or the Master 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 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 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  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
or a Servicer,  as  applicable,  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 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 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 or
the Master  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 or the
Master 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  Sub-Servicer  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 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 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 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,  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 a Custodian,
it being  understood and agreed that the Trustee,  Trust  Administrator  and any Custodian 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,  the  Certificates,  any  Custodial  Agreement,  any  Interest  Rate Cap  Agreement,  any Swap
Agreement,  any Designated Servicing Agreement,  or (b) the performance of any of the Trustee's duties hereunder or under any Custodial
Agreement,  Interest Rate Cap Agreement,  Swap Agreement or Designated Servicing  Agreement,  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  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,  the Modification Oversight
Agent 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,  the  Certificates,  any
Custodial  Agreement,  any  Interest  Rate Cap  Agreement,  any Swap  Agreement  and any  Designated  Servicing  Agreement,  or (b) the
performance of any of the Trust Administrator's  duties hereunder or under any Custodial Agreement,  Interest Rate Cap Agreement,  Swap
Agreement or Designated Servicing 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,  the Modification
Oversight  Agent  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, shall 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.    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  of such rate and such rate shall be final and  binding,  absent a manifest  error of the Trust
Administrator.

                                                              ARTICLE XI

                                                              TERMINATION

                  As set forth in Article XI of the Series Supplement.

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;  or to comply with the provisions of
         Regulation AB.

                  (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 Special Servicer,  the Modification  Oversight Agent, the Seller, the Trust Administrator and
the Trustee with the consent of the Holders of Certificates  evidencing,  in the aggregate,  not less than 66 2/3% of the Voting Rights
of all the  Certificates  for the purpose of adding any 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 of the Stated Principal Balance of the Mortgage Loans specified in  Sections 11.01(d)  or (e)  relating to a Terminating
Auction Sale, or (vi) modify the provisions of this Section 12.01.

                  It shall not be necessary for the consent of  Certificateholders  under this  Section 12.01 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 Modification  Oversight Agent, the Servicers,  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 12.01 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  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 3.21,  without the
consent of 100% of the Holders of the Class P Certificates.

                  (i)      Notwithstanding  anything to the contrary in this Section 12.01,  the Master Servicer, the Special Servicer,
the Modification  Oversight Agent, the Servicers,  the Seller, the Trust Administrator and the Trustee shall reasonably  cooperate with
the  Depositor  and its counsel to enter into such  amendments  or  modifications  to the  Agreement as may be necessary to comply with
Regulation AB and any interpretation thereof by the Commission.

                  (j)      Without  the  consent  of the Swap  Counterparty,  the  Seller  and the  Depositor  shall not enter into any
amendment or modification of the terms and provisions of this Agreement if such amendment or modification  would  materially  adversely
affect the rights and interests of the Swap Counterparty hereunder.

                  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 GOVERNED BY AND  CONSTRUED IN  ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK,  WITHOUT
REGARD TO THE CONFLICT OF LAW PRINCIPALS THEREOF, OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW.

                  SECTION 12.04.    Intention of Parties.

                  (a)      It is the express  intent of the Depositor,  the Seller,  the Master  Servicer,  the Special  Servicer,  the
Modification  Oversight Agent, 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.

                  In addition to other notices provided under this Agreement,  the Trust Administrator shall notify the Rating Agencies
in writing:  (a) of any  substitution  of any Mortgage  Loan;  (b) of any payment or draw on any  insurance  policy  applicable  to the
Mortgage  Loans;  (c) of  the final  payment of any  amounts  owing to a Class of  Certificates;  (d) any  Event of Default  under this
Agreement; and (e) in the event any Mortgage Loan is purchased in accordance with this Agreement.

                  If any one or more of the  covenants,  agreements,  provisions  or terms of this  Agreement  shall be for any  reason
whatsoever held invalid, then such covenants,  agreements,  provisions or terms shall be deemed severable from the remaining covenants,

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

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 is the subject of
this agreement, the trust created by this agreement is not authorized and has no power to:

                  (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
(other than WMMSC),  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 internet 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
neither  (i) promotions  undertaken by the Depositor,  the Seller,  the Master  Servicer,  any Servicer  (other than WMMSC),  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  nor (ii) serving the refinancing  needs of a Mortgagor who,
without  solicitation,  contacts  either party in connection  with the refinance of such Mortgage or Mortgage  Loan,  shall  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,  any Servicer  (other than WMMSC),  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.

                  WMMSC  covenants  and agrees  that it shall not take any action to  solicit  the  refinancing  of any  Mortgage  Loan
following the date hereof or provide  information to any other entity to solicit the refinancing of any Mortgage Loan;  provided,  that
the foregoing  shall not preclude WMMSC or any of its  affiliates  from  (a) engaging  in general  solicitations  to its customer base,
including  by mass  mailing or as part of monthly or  periodic  statements  mailed to its  borrowers  or to holders of deposit or other
accounts,  (b) engaging in  solicitations  to the general  public,  including  without  limitation by mass mailing,  newspaper,  radio,
television  or other media which are not  specifically  directed  toward the  Mortgagors,  (c) engaging  in  solicitations  of optional
insurance or other bank products (not  including  mortgage  loans),  (d) refinancing  the Mortgage Loan of any Mortgagor  who,  without
solicitation,  contacts WMMSC to request the  refinancing  of the related  Mortgage Loan or  (e) engaging  in any action to solicit the
refinancing  of any Mortgage  Loan to the extent such action would be  permitted  under the Fannie Mae Selling  Guide or the Fannie Mae
Servicing Guide,  provided that WMMSC agrees that it shall not, in engaging in any such  solicitation,  specifically  target any of the
Mortgage Loans.

                                                             ARTICLE XIII

                                                        EXCHANGE ACT REPORTING

                  SECTION 13.01.    Commission Reporting.

                  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,  10-D 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 or Master  Servicer,  as specified  below,  shall sign and the Trust
Administrator shall file (via EDGAR) such Forms on behalf of the Depositor.

                  Form 10-D and Form 10-K require the  registrant  to indicate  (by checking  "yes" or "no") that it "(1) has filed all
reports  required to be filed by  Section 13  or 15(d) of the Exchange Act during the  preceding 12 months (or for such shorter  period
that the  registrant was required to file such reports),  and (2) has been subject to such filing  requirements  for the past 90 days."
The Depositor  hereby  represents to the Trust  Administrator  that, as of the Closing Date,  the Depositor has filed all such required
reports  during the preceding 12 months and that it has been subject to such filing  requirement  for the past  90 days.  The Depositor
shall  notify the Trust  Administrator  in  writing,  no later than the fifth  calendar  day after the related  Distribution  Date with
respect to the filing of a report on Form 10-D and no later  than  March 15th with  respect to the filing of a report on Form 10-K,  if
the answer to each question should be "no." The Trust  Administrator  shall be entitled to rely on such  representations  in preparing,
executing and/or filing any such report.

                  SECTION 13.02.    Form 10-D Reporting

                  Within 15 days after each  Distribution  Date (subject to permitted  extensions  under the Exchange  Act),  the Trust
Administrator  shall prepare and file on behalf of the Trust Fund any Form 10-D  required by the Exchange Act, in form and substance as
required  by the  Exchange  Act.  The Trust  Administrator  shall file each  Form 10-D  with a copy of the  related  Monthly  Statement
attached  thereto.  Any  disclosure  in addition to the Monthly  Statement  that is required to be included on  Form 10-D  ("Additional
Form 10-D  Disclosure")  shall be  reported  by the parties set forth on Exhibit S to the  Depositor  and the Trust  Administrator  and
directed  and  approved  by the  Depositor  pursuant  to the  following  paragraph  and the Trust  Administrator  shall have no duty or
liability  for any failure  hereunder to  determine or prepare any  Additional  Form 10-D  Disclosure,  except as set forth in the next
paragraph.

                  As set forth on Exhibit S hereto,  within five calendar days after the related Distribution Date, (i) the parties set
forth thereon shall be required to provide to the Trust  Administrator and the Depositor,  to the extent known by a responsible officer
thereof, in  EDGAR-compatible  form, or in such other form as otherwise agreed upon by the Trust Administrator and such party, the form
and substance of any Additional Form 10-D Disclosure,  if applicable,  together with an additional disclosure  notification in the form
of Exhibit W  hereto (an "Additional  Disclosure  Notification")  and (ii) the  Depositor shall approve,  as to form and substance,  or
disapprove,  as the  case  may be,  the  inclusion  of the  Additional  Form 10-D  Disclosure  on  Form 10-D.  The  Depositor  shall be
responsible  for any reasonable  fees and expenses  assessed or incurred by the Trust  Administrator  in connection  with including any
Additional Form 10-D Disclosure on Form 10-D pursuant to this paragraph.

                  After preparing the Form 10-D,  the Trust Administrator shall forward electronically a draft copy of the Form 10-D to
the Depositor as soon as possible,  however,  in no event later than the 11th calendar day after the related  Distribution Date. Within
two business  days of receipt,  but in no event no later than the Business Day prior to the date  specified in the next  sentence,  the
Depositor  shall  notify the Trust  Administrator  of any changes to or approval  of such  Form 10-D.  In the absence of receipt of any
written  changes or approval,  the Trust  Administrator  shall be entitled to assume that such Form 10-D is in final form and the Trust
Administrator  may proceed with the execution and filing of the  Form 10-D.  No later than two Business Days prior to the 15th calendar
day after the related  Distribution  Date, a duly  authorized  representative  of the Master  Servicer shall sign the  Form 10-D.  If a
Form 10-D  cannot be filed on time or if a previously  filed Form 10-D needs to be amended,  the Trust  Administrator  shall follow the
procedures  set forth in  Section 13.05.  Promptly  (but no later than one Business  Day) after filing with the  Commission,  the Trust
Administrator  shall make available on its internet  website a final  executed copy of each  Form 10-D  prepared and filed by the Trust
Administrator.  Each party to this Agreement  acknowledges  that the performance by the Master Servicer and the Trust  Administrator of
its duties under this  Section 13.02  related to the timely  preparation,  execution  and filing of Form 10-D is  contingent  upon such
parties  strictly  observing all applicable  deadlines in the performance of their duties under this  Section 13.02.  Neither the Trust
Administrator  nor the Master Servicer shall have any liability for any loss,  expense,  damage or claim arising out of or with respect
to any failure to properly  prepare,  timely  execute  and/or  timely file such  Form 10-D,  where such failure  results from the Trust
Administrator's  inability or failure to obtain or receive,  on a timely basis,  any information  from any other party hereto needed to
prepare, arrange for execution or file such Form 10-D, not resulting from its own negligence, bad faith or willful misconduct.

                  SECTION 13.03.    Form 10-K Reporting

                  Within 90 days  after  the end of each  fiscal  year of the  Trust or such  earlier  date as may be  required  by the
Exchange  Act (the "10-K  Filing  Deadline")  (it being  understood  that the fiscal year for the Trust ends on  December  31st of each
year),  commencing in March of the calendar year  following the calendar year in which the Closing Date of the related  Series  occurs,
the Trust  Administrator  shall prepare and file on behalf of the Trust a Form 10-K,  in form and substance as required by the Exchange
Act.  Each such  Form 10-K  shall  include  the  following  items,  in each case to the extent  they have been  delivered  to the Trust
Administrator  within the  applicable  time  frames set forth in this  Agreement,  the  related  Custodial  Agreements  and the related
Designated  Servicing Agreement,  (i) the Item 1123  Certification for each Servicer,  each Additional  Servicer,  the Master Servicer,
Trust  Administrator,  the  Modification  Oversight  Agent and any Servicing  Function  Participant  engaged by such parties  (each,  a
"Reporting  Servicer")  as described  under  Section 13.06,  (ii)(A) the  Assessment  of Compliance  with  servicing  criteria for each
Reporting  Servicer as described  under  Section 13.07,  and (B) if any Reporting  Servicer's  Assessment of Compliance  identifies any
material instance of noncompliance,  disclosure  identifying such instance of noncompliance,  or if any Reporting Servicer's Assessment
of Compliance  is not included as an exhibit to such  Form 10-K,  disclosure  that such report is not included and an  explanation  why
such report is not included,  (iii)(A) the Accountant's Attestation for each Reporting Servicer, as described under Section 13.08,  and
(B) if any  Accountant's  Attestation  identifies  any material  instance of  noncompliance,  disclosure  identifying  such instance of
noncompliance,  or if any such  Accountant's  Attestation is not included as an exhibit to such Form 10-K,  disclosure that such report
is not  included  and an  explanation  why such  report is not  included,  and (iv) a  Sarbanes-Oxley  Certification  as  described  in
Section 13.09;  provided,  however,  that the Trust  Administrator,  at its  discretion,  may omit  from the  Form 10-K  any  Item 1123
Certification,  Assessment of Compliance or Accountants  Attestation  that is not required to be filed with such Form 10-K  pursuant to
Regulation AB.  Any  disclosure  or  information  in addition to  (i) through  (iv) above that is required to be included on  Form 10-K
("Additional  Form 10-K  Disclosure") shall be reported by the parties set forth on Exhibit Y to the Depositor and Trust  Administrator
and directed and approved by the  Depositor  pursuant to the  following  paragraph  and the Trust  Administrator  shall have no duty or
liability  for any failure  hereunder to  determine or prepare any  Additional  Form 10-K  Disclosure,  except as set forth in the next
paragraph.

                  As set forth on Exhibit Y  hereto,  no later than March 15 of each year that the Trust is subject to the Exchange Act
reporting  requirements,  commencing in the calendar year  following the calendar year in which the Closing Date of the related  Series
occurs,  (i) the  parties set forth on Exhibit Y  shall be required to provide to the Trust  Administrator  and the  Depositor,  to the
extent known by a responsible officer thereof,  in  EDGAR-compatible  form, or in such other form as otherwise agreed upon by the Trust
Administrator  and such party,  the form and  substance  of any  Additional  Form 10-K  Disclosure,  if  applicable,  together  with an
Additional Disclosure Notification and (ii) the Depositor shall approve, as to form and substance,  or disapprove,  as the case may be,
the inclusion of the Additional  Form 10-K  Disclosure on Form 10-K.  The Depositor  shall be responsible  for any reasonable  fees and
expenses  assessed or incurred by the Trust  Administrator  in  connection  with  including  any  Additional  Form 10-K  Disclosure  on
Form 10-K pursuant to this paragraph.

                  After preparing the Form 10-K,  the Trust Administrator shall forward electronically a draft copy of the Form 10-K to
the Depositor for review.  Within three (3) business days of receipt,  but in no event later than March 25, the Depositor  shall notify
the Trust  Administrator  in writing (which may be furnished  electronically)  of any changes to or approval of such Form 10-K.  In the
absence of receipt of any written  changes or approval the Trust  Administrator  shall be entitled to assume that such  Form 10-K is in
final form. No later than the close of business on the 4th Business Day prior to the 10-K Filing  Deadline,  the  Depositor  shall sign
the  Form 10-K  and return an  electronic  or fax copy of such  signed  Form 10-K  (with an  original  executed  hard copy to follow by
overnight  mail) to the Trust  Administrator.  If a Form 10-K  cannot be filed on time or if a previously  filed  Form 10-K needs to be
amended,  the Trust Administrator  shall follow the procedures set forth in Section 13.05.  Promptly (but no later than 1 Business Day)
after filing with the Commission,  the Trust  Administrator  shall make available on its internet website a final executed copy of each
Form 10-K  prepared  and filed by the Trust  Administrator.  The parties to this  Agreement  acknowledge  that the  performance  by the
Master Servicer and the Trust  Administrator  of its duties under this  Section 13.03  related to the timely  preparation and filing of
Form 10-K is contingent  upon such parties (and the  Custodians,  Designated  Servicers and any Additional  Servicer or other Servicing
Function  Participant)  strictly observing all applicable deadlines in the performance of their duties under Article XIII.  Neither the
Trust  Administrator  nor the Master  Servicer shall have any liability for any loss,  expense,  damage or claim arising out of or with
respect  to any  failure  to  properly  prepare  and/or  timely  file  such  Form 10-K,  where  such  failure  results  from the  Trust
Administrator's  inability or failure to obtain or receive,  on a timely basis,  any information  from any other party hereto needed to
prepare, arrange for execution or file such Form 10-K, not resulting from its own negligence, bad faith or willful misconduct.

                  SECTION 13.04.    Form 8-K Reporting

                  Within four (4) Business Days after the occurrence of an event  requiring  disclosure on Form 8-K (each such event, a
"Reportable  Event"),  and if requested by the  Depositor,  the Trust  Administrator  shall prepare and file on behalf of the Trust any
Form 8-K,  as required by the Exchange Act, provided that the Depositor shall file the initial Form 8-K in connection with the issuance
of the  Certificates.  Any  disclosure or  information  related to a Reportable  Event or that is otherwise  required to be included on
Form 8-K  ("Form 8-K  Disclosure  Information")  shall be reported by the parties set forth on Exhibit U to the Depositor and the Trust
Administrator and directed and approved by the Depositor  pursuant to the following  paragraph and the Trust  Administrator  shall have
no duty or liability for any failure hereunder to determine or prepare any Form 8-K Disclosure  Information or any Form 8-K,  except as
set forth in the next paragraph.

                  As set forth on Exhibit U hereto, for so long as the Trust is subject to the Exchange Act reporting requirements,  no
later than the end of business(New  York City time) on the 2nd Business Day after the occurrence of a Reportable  Event (i) the parties
to this transaction  shall be required to provide to the Trust  Administrator  and the Depositor,  to the extent known by a responsible
officer thereof,  in  EDGAR-compatible  form, or in such other form as otherwise agreed upon by the Trust Administrator and such party,
the form and substance of any Form 8-K Disclosure Information,  if applicable,  together with an Additional Disclosure Notification and
(ii) the  Depositor  shall  approve,  as to form and  substance,  or  disapprove,  as the case may be, the  inclusion  of the  Form 8-K
Disclosure  Information.  The Depositor  shall be responsible  for any reasonable  fees and expenses  assessed or incurred by the Trust
Administrator in connection with including any Form 8-K Disclosure Information on Form 8-K pursuant to this paragraph.

                  After preparing the Form 8-K,  the Trust Administrator  shall forward  electronically a draft copy of the Form 8-K to
the Depositor for review.  Promptly,  but no later than the close of business on the 3rd business day after the Reportable  Event,  the
Depositor  shall notify the Trust  Administrator  in writing of any changes to or approval of such Form 8-K.  In the absence of receipt
of any written  changes or  approval,  the Trust  Administrator  shall be entitled to assume that such  Form 8-K is in final form and a
duly  authorized  representative  of the Trust  Administrator  may  proceed  with the  execution  and  filing of the  Form 8-K.  A duly
authorized  representative  of the Master  Servicer shall sign the Form 8-K.  If a Form 8-K  cannot be filed on time or if a previously
filed Form 8-K needs to be amended,  the Trust Administrator  shall follow the procedures set forth in Section 13.05.  Promptly (but no
later than one Business Day) after filing with the Commission,  the Trust  Administrator shall make available on its internet website a
final executed copy of each Form 8-K  prepared and filed by the Trust  Administrator.  The parties to this Agreement  acknowledge  that
the  performance  by the Trust  Administrator  and the Master  Servicer of its duties  under this  Section 13.04  related to the timely
preparation and filing of Form 8-K is contingent upon such parties  strictly  observing all applicable  deadlines in the performance of
their  duties under this  Section 13.04.  Neither the Master  Servicer nor the Trust  Administrator  shall have any  liability  for any
loss,  expense,  damage or claim arising out of or with respect to any failure to properly  prepare  and/or timely file such  Form 8-K,
where such  failure  results  from the Trust  Administrator's  inability  or  failure  to obtain or  receive,  on a timely  basis,  any
information  from any other party hereto needed to prepare,  arrange for execution or file such  Form 8-K,  not resulting  from its own
negligence, bad faith or willful misconduct.

                  SECTION 13.05.    Delisting; Amendment; Late Filing of Reports

                  On or before January 30 of the first year in which the Trust  Administrator  is able to do so under  applicable  law,
the Trust Administrator shall prepare and file a Form 15 Suspension  Notification  relating to the automatic suspension of reporting in
respect of the Trust under the Exchange Act.

                  In the event that the Trust  Administrator  is unable to timely file with the Commission all or any required  portion
of any Form 8-K,  10-D or 10-K required to be filed by this Agreement because required disclosure  information was either not delivered
to it or delivered to it after the delivery  deadlines  set forth in this  Agreement or for any other reason,  the Trust  Administrator
shall promptly notify  electronically  the Depositor.  In the case of Form 10-D and 10-K, the parties to this Agreement shall cooperate
to prepare and file a Form 12b-25 and a 10-D/A and 10-K/A as  applicable,  pursuant to  Rule 12b-25 of the Exchange Act. In the case of
Form 8-K,  the Trust  Administrator  shall,  upon receipt of all required  Form 8-K  Disclosure  Information  and upon the approval and
direction of the  Depositor,  include  such  disclosure  information  on the next  Form 10-D.  In the event that any  previously  filed
Form 8-K,  10-D or 10-K needs to be amended in  connection  with any  additional  Form 10-D  Disclosure  (other than for the purpose of
restating the Monthly Report),  the Trust Administrator shall  electronically  notify the Depositor and such parties shall cooperate to

prepare any necessary  Form 8-K/A,  10-D/A or 10-K/A.  Any Form 15, Form 12b-25 or any amendment to Form 8-K or 10-D shall be signed by
a duly authorized  representative  of the Master  Servicer.  Any amendment to Form 10-K  shall be signed by the Depositor.  The parties
to this Agreement  acknowledge  that the  performance  by the Trust  Administrator  and the Master  Servicer of their duties under this
Section 13.05  related to the timely  preparation  and filing of Form 15, a Form 12b-25 or any  amendment to Form 8-K,  10-D or 10-K is
contingent  upon each such party  performing  its duties  under this  Section 13.05.  Neither  the Trust  Administrator  nor the Master
Servicer  shall have any  liability  for any loss,  expense,  damage or claim arising out of or with respect to any failure to properly
prepare  and/or  timely file any such Form 15, Form 12b-25 or any  amendments to Forms 8-K,  10-D or 10-K,  where such failure  results
from the Trust  Administrator's  inability or failure to obtain or receive,  on a timely basis,  any  information  from any other party
hereto  needed to prepare,  arrange for execution or file such Form 15, Form 12b-25 or any  amendments to Forms 8-K, 10-D or 10-K,  not
resulting from its own negligence, bad faith or willful misconduct.

                  SECTION 13.06.    Annual Statements of Compliance

                  The Master Servicer,  the Trust  Administrator,  the Modification  Oversight Agent and each Servicer shall deliver or
otherwise make available (and the Master Servicer,  the Trust Administrator,  the Modification  Oversight Agent and each Servicer shall
cause any Servicing Function  Participant  engaged by it to deliver or otherwise make available) to the Depositor,  the Trustee and the
Trust  Administrator on or before March 15 of each year,  commencing in March of the calendar year following the calendar year in which
the Closing Date of the related  Series  occurs,  an Officer's  Certificate  (an  "Item 1123  Certificate")  stating,  as to the signer
thereof,  that (A) a review of such  party's  activities  during the  preceding  calendar  year or portion  thereof and of such party's
performance under this Agreement,  or such other applicable  agreement in the case of a Servicing Function  Participant,  has been made
under such officer's  supervision and (B) to the best of such officer's  knowledge,  based on such review, such party has fulfilled all
its obligations  under this Agreement,  or such other  applicable  agreement in the case of a Servicing  Function  Participant,  in all
material  respects  throughout  such year or portion  thereof,  or, if there has been a failure to fulfill any such  obligation  in any
material  respect,  specifying  each such failure known to such officer and the nature and status  thereof.  Promptly  after receipt of
each such Item 1123  Certificate,  the Depositor  shall review such Item 1123  Certificate  and, if applicable,  consult with each such
party, as applicable,  as to the nature of any failures by such party, in the fulfillment of any of such party's obligations  hereunder
or, in the case of an  Additional  Servicer,  under such other  applicable  agreement,  provided,  however,  that Wells  Fargo,  in its
capacity as a Servicer,  shall only be obligated to provide the Item 1123  Officer's  Certificate to the Master Servicer and the Master
Servicer shall forward such 1123 Officer's  Certificate to the Depositor,  the Trustee and the Trust  Administrator  or, if there is no
Master  Servicer,  to the Depositor  and the  Depositor  shall  forward such 1123  Officer's  Certificate  to the Trustee and the Trust
Administrator.

                  The Master Servicer shall include all annual statements of compliance  received by it from each Servicer with its own
annual statement of compliance to be submitted to the Trust Administrator pursuant to this Section 13.06.

                  In the event the Master Servicer,  the Trust Administrator or any Servicing Function  Participant engaged by any such
party is  terminated  or resigns  pursuant  to the terms of this  Agreement,  or any  applicable  agreement  in the case of a Servicing
Function  Participant,  as the case may be, such party shall provide an Item 1123 Certificate pursuant to this Section 13.06 or to such
applicable agreement, as the case may be, notwithstanding any such termination, assignment or resignation.

                  The Master Servicer shall enforce any obligation of any Designated  Servicer,  to the extent set forth in the related
Designated Servicing Agreement,  to deliver to the Master Servicer an Item 1123  Certificate as may be required pursuant to the related
Designated  Servicing  Agreement.  The Master Servicer shall include such Item 1123  Certificate with its own Item 1123  Certificate to
be submitted to the Trust Administrator, the Depositor and the Trustee pursuant to this Section 13.06.

                  SECTION 13.07.    Annual Assessments of Compliance.

                  By March 15 of each year,  commencing in March of the calendar year  following the calendar year in which the Closing
Date of the related Series occurs, the Master Servicer,  the Trust Administrator,  the Modification  Oversight Agent and each Servicer,
each at its own  expense,  shall  furnish  or  otherwise  make  available,  and each such  party  shall  cause any  Servicing  Function
Participant  engaged by it to furnish or otherwise make available,  each at its own expense,  to the Trust  Administrator,  the Trustee
and the Depositor,  a report on an assessment of compliance with the Relevant  Servicing  Criteria (an "Assessment of Compliance") that
contains (A) a statement by such party of its  responsibility  for assessing  compliance with the Relevant  Servicing Criteria for each
party as set forth on Exhibit R,  (B) a statement that such party used the Relevant  Servicing  Criteria to assess  compliance with the
Relevant  Servicing  Criteria,  (C) such party's assessment of compliance with the Relevant Servicing Criteria as of and for the fiscal
year covered by the Form 10-K  required to be filed pursuant to  Section 13.03,  including,  if there has been any material instance of
noncompliance  with the Relevant  Servicing  Criteria,  a discussion of each such failure and the nature and status thereof,  and (D) a
statement that a registered  public  accounting  firm has issued an Accountant's  Attestation on such party's  Assessment of Compliance
with the Relevant Servicing Criteria as of and for such period.

                  No later than the end of each fiscal year for the Trust for which a 10-K is required to be filed, each Servicer,  the
Modification  Oversight  Agent and the  Master  Servicer  shall  each  forward to the Trust  Administrator  the name of each  Servicing
Function  Participant  engaged by it and what Relevant Servicing Criteria will be addressed in the Assessment of Compliance prepared by
such  Servicing  Function  Participant;  provided,  however,  that the  Master  Servicer  need not  provide  information  to the  Trust
Administrator  so long as the  Master  Servicer  and the  Trust  Administrator  are the same  person.  When the  Master  Servicer,  the
Modification  Oversight Agent and each Servicer (or any Servicing  Function  Participant  engaged by them) submit their  Assessments of
Compliance to the Trust  Administrator,  such parties shall also at such time include the Assessments of Compliance  (and  Accountant's
Attestation)  pursuant to Section 13.08 of each Servicing Function Participant engaged by it; provided,  however,  that Wells Fargo, in
its  capacity as a  Servicer,  shall only be  obligated  to provide  disclosure  pursuant  to the first and second  paragraphs  of this
Section 13.07  to the Master Servicer and the Master  Servicer shall forward such items to the  appropriate  parties or, if there is no
Master Servicer, to the Depositor and the Depositor shall forward such items to the Trustee and the Trust Administrator.

                  Promptly  after  receipt of each  Assessment  of  Compliance,  the  Depositor  shall  review each such report and, if
applicable,  consult with the Master  Servicer,  the Trust  Administrator,  the  Modification  Oversight  Agent,  each Servicer and any
Servicing  Function  Participant  engaged by such parties as to the nature of any material instance of noncompliance  with the Relevant
Servicing  Criteria by each such party.  None of such parties shall be required to deliver any such  assessments  until March 30 in any
given year so long as it has received written  confirmation  from the Depositor that a Form 10-K is not required to be filed in respect
of the Trust for the preceding calendar year.

                  The Master  Servicer shall include all annual  reports on assessment of compliance  received by it from the Servicers
with its own assessment of compliance to be submitted to the Trust Administrator pursuant to this Section 13.07.

                  In the event the Master Servicer,  the Trust Administrator or any Servicing Function  Participant engaged by any such
party is terminated,  assigns its rights and  obligations  under,  or resigns  pursuant to, the terms of this  Agreement,  or any other
applicable  agreement,  as the  case  may be,  such  party  shall  provide  a report  on  assessment  of  compliance  pursuant  to this
Section 13.07, or such other applicable agreement, notwithstanding any such termination, assignment of resignation.

                  The Master Servicer shall enforce any obligation of the Designated  Servicers and the  Custodians,  to the extent set
forth in the related  Designated  Servicing  Agreement or Custodial  Agreement,  as  applicable,  to deliver to the Master  Servicer an
Assessment  of  Compliance  within the time frame set forth in, and in such form and  substance  as may be  required  pursuant  to, the
related Designated  Servicing  Agreement or Custodial  Agreement,  as applicable.  The Master Servicer shall include such Assessment of
Compliance  with its own  Assessment  of  Compliance  to be  submitted  to the Trust  Administrator  and the  Trustee  pursuant to this
Section 13.07.

                  SECTION 13.08.    Accountant's Attestation

                  By March 15 of each year,  commencing in the calendar  year  following the calendar year in which the Closing Date of
the related Series occurs, the Master Servicer, the Trust Administrator,  the Modification  Oversight Agent and each Servicer,  each at
its own expense,  shall cause, and each such party shall cause any Servicing Function  Participant  engaged by it to cause, each at its
own  expense,  a  registered  public  accounting  firm  (which  may also  render  other  services  to the  Master  Servicer,  the Trust
Administrator,  the Modification Oversight Agent or a Servicer or such other Servicing Function  Participants,  as the case may be) and
that is a member of the American  Institute of Certified  Public  Accountants to furnish a report (the  "Accountant's  Attestation") to
the Trust Administrator and the Depositor,  to the effect that (i) it has obtained a representation  regarding certain matters from the
management of such party,  which includes an assertion that such party has complied with the Relevant Servicing  Criteria,  and (ii) on
the basis of an examination  conducted by such firm in accordance with standards for attestation  engagements  issued or adopted by the
PCAOB,  it is expressing an opinion as to whether such party's  compliance  with the Relevant  Servicing  Criteria was fairly stated in
all material  respects,  or it cannot  express an overall  opinion  regarding such party's  assessment of compliance  with the Relevant
Servicing  Criteria.  In the event that an overall opinion cannot be expressed,  such registered  public accounting firm shall state in
such report why it was unable to express  such an opinion.  Such report must be  available  for general use and not contain  restricted
use language.

                  Promptly after receipt of such  Accountant's  Attestations from the Master Servicer,  each Servicer,  each Designated
Servicer,  each Custodian,  the Trust Administrator,  the Modification Oversight Agent or any Servicing Function Participant engaged by
such  parties,  (i) the  Depositor  shall  review the report  and, if  applicable,  consult  with such  parties as to the nature of any
defaults  by such  parties,  in the  fulfillment  of any of each such  party's  obligations  hereunder  or under  any other  applicable
agreement,  and (ii) the Trust  Administrator  shall  confirm  that each  Assessment  of  Compliance  is coupled  with an  Accountant's
Attestation  meeting the requirements of this  Section 13.08 and notify the Depositor of any exceptions.  None of such parties shall be
required to deliver any such  assessments  until March 30 in any given year so long as it has received  written  confirmation  from the
Depositor that a Form 10-K is not required to be filed in respect of the Trust for the preceding calendar year.

                  The Master Servicer shall include each such attestation  furnished to it by the Servicers with its own attestation to
be submitted to the Trust Administrator pursuant to this Section 13.08.

                  In the event the Master Servicer, the Trust Administrator,  the Custodians,  any Servicer, the Modification Oversight
Agent or any Servicing Function  Participant engaged by any such party, is terminated,  assigns its rights and duties under, or resigns
pursuant to the terms of, this  Agreement,  or any applicable  Custodial  Agreement,  Designated  Servicing  Agreement or  Subservicing

Agreement,  as the case may be,  such party  shall,  at its sole  expense,  cause a  registered  public  accounting  firm to provide an
attestation pursuant to this Section 13.08,  or such other applicable  agreement,  notwithstanding any such termination,  assignment or
resignation.

                  The Master Servicer shall enforce any obligation of the Designated  Servicers and the  Custodians,  to the extent set
forth in the related  Designated  Servicing  Agreement and the related  Custodial  Agreement,  as applicable,  to deliver to the Master
Servicer an  attestation  as may be required  pursuant  to, the related  Designated  Servicing  Agreement  or  Custodial  Agreement  as
applicable.  The Master  Servicer  shall include each such  attestation  with its own  Accountant's  Attestation to be submitted to the
Trust Administrator pursuant to this Section 13.08.

                  SECTION 13.09.    Sarbanes-Oxley Certification

                  Each Form 10-K shall include a certification (the "Sarbanes-Oxley  Certification")  required to be included therewith
pursuant to the Sarbanes-Oxley Act. Each Servicer,  the Master Servicer,  the Modification  Oversight Agent and the Trust Administrator
shall provide,  and each Servicer,  the Master Servicer,  the Modification  Oversight Agent and the Trust Administrator shall cause any
Servicing  Function  Participant  engaged by it to, provide to the Person who signs the  Sarbanes-Oxley  Certification (the "Certifying
Person"),  by March 15 of each year in which the Trust is subject to the  reporting  requirements  of the  Exchange  Act and  otherwise
within a reasonable  period of time upon request,  a certification  (each, a "Back-Up  Certification"),  in the form attached hereto as
Exhibit V,  upon which the  Certifying  Person,  the entity for which the  Certifying  Person  acts as an  officer,  and such  entity's
officers,  directors and  Affiliates  (collectively  with the Certifying  Person,  "Certification  Parties") can  reasonably  rely. The
Depositor shall serve as the Certifying  Person on behalf of the Trust. In the event the Master  Servicer,  the Trust  Administrator or
any Servicing  Function  Participant  engaged by such party is terminated or resigns  pursuant to the terms of this  Agreement,  or any
applicable  Subservicing  Agreement,  as the case may be, such party shall provide a Back-Up  Certification  to the  Certifying  Person
pursuant to this  Section 13.09  with  respect to the period of time it was subject to this  Agreement or any  applicable  Subservicing
Agreement, as the case may be.

                  The Master Servicer shall enforce any obligation of the Designated Servicers,  to the extent set forth in the related
Designated  Servicing  Agreement,  to deliver to the Master Servicer a  certification  similar to the Back-Up  Certification  as may be
required pursuant to the related Designated Servicing Agreement.

                  SECTION 13.10.    Indemnification

                  Each party  required to deliver an Assessment  of  Compliance  and an  Accountant's  Attestation  and/or an Item 1123

Servicer and the Depositor and each of their  directors,  officers,  employees,  agents,  and  affiliates  from and against any and all

                  evidencing a percentage  interest in the distributions  allocable to the Certificates of the  above-referenced  Class
                  with respect to a Trust Fund  consisting  primarily of a pool of adjustable  rate  conventional  mortgage  loans (the

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 Modification  Oversight Agent, the Trustee or the Trust  Administrator
referred to below or any of their  respective  affiliates.  Neither this  Certificate  nor the Mortgage Loans are guaranteed or insured
by any governmental agency or instrumentality.

         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 Suisse First Boston Mortgage  Securities  Corp. (the  "Depositor").  The Trust Fund
was created  pursuant to a Series  Supplement  dated as of the  Cut-off  Date  specified  above and the  Standard  Terms of Pooling and
Servicing  Agreement dated  February 1,  2007  (collectively,  the "Agreement") by and among the Depositor,  the Seller(s),  the Master
Servicer,  the Trust  Administrator,  the Special  Servicer,  the Modification  Oversight Agent, the Trustee and the Servicers that are
party to the Series  Supplement.  To the extent not defined herein, the capitalized 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.

         [For  Privately  Offered Certs only] [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 affect 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 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. 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.

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

                  secured by first liens on one- to four-family residential properties.

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 Modification  Oversight Agent, the Trustee or the Trust  Administrator
referred to below or any of their  respective  affiliates.  Neither this  Certificate  nor the Mortgage Loans are guaranteed or insured
by any governmental agency or instrumentality.

         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 Suisse First Boston Mortgage  Securities  Corp.  (the  "Depositor").  The Trust Fund was created
pursuant  to a Series  Supplement  dated as of the  Cut-off  Date  specified  above and the  Standard  Terms of Pooling  and  Servicing
Agreement dated February 1,  2007 (collectively,  the "Agreement") by and among the Depositor,  the Seller(s), the Master Servicer, the
Trust  Administrator,  the Special  Servicer,  the  Modification  Oversight  Agent, the Trustee and the Servicers that are party to the
Series  Supplement.  To the extent not defined herein,  the capitalized  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 the Agreement,  no transfer of an ERISA-Restricted  Certificate shall be made unless the Trust Administrator 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 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. 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
Trust  Administrator  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 Trust  Administrator  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.

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 that are Book-Entry  Certificates 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  that are  Book-Entry
Certificates on such Distribution Date, the close of business on the Business Day immediately preceding such Distribution Date.

         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 Modification  Oversight Agent, 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 the Trust  Administrator  in New York,  New York,  accompanied  by a
written  instrument of transfer in form  satisfactory to the Trust  Administrator  and the  Certificate  Registrar duly executed by the
holder hereof or such holder's  attorney duly  authorized in writing,  and thereupon one or more new  Certificates of the same 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.

         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.

have not been registered  under the Securities Act of 1933, as amended (the "Act"),  and are being disposed by us in a transaction that
is exempt from the  registration  requirements of the Act, (b) we have not offered or sold any  Certificates to, or solicited offers to

would be deemed,  or taken any other  action  which would  result in, a violation  of  Section 5  of the Act,  (c) to the extent we are
disposing of a Class AR  Certificate,  we have no knowledge the  Transferee is not a Permitted  Transferee and (d) to the extent we are
disposing of a  Certificate  in reliance  upon  Regulation S under the Act,  that such  transfer has been  effected  pursuant to and in
accordance with Regulation S under the Act, and accordingly that:

                        (1)   the offer of the Certificates was not made to a person in the United States;

                        [(2)  at the time the buy order was  originated,  the  transferee  was outside the United  States or we and any

                        [(2)  the transaction was executed in, on or through the facilities of a designated  offshore securities market
                              and neither us nor any person  acting on our behalf knows that the  transaction  was  prearranged  with a
                              buyer in the United States;]*

                        *  Insert one of these two provisions.

                        (3)   no directed  selling efforts have been made in contravention of the requirements of Rule 903(b) or 904(b)
                              of Regulation S, as applicable; and

                        (4)   the transaction is not part of a plan or scheme to evade the registration requirements of the Act.

plan will not result in a non-exempt  prohibited  transaction  under  Section 406  of ERISA 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 or (iii) if, in the case of an  ERISA-Restricted  Certificates  that have been the subject of an
ERISA-Qualifying  Underwriting,  we are an insurance company, we are 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
our purchase  and holding of such  Certificates  are covered  under  Sections I and III of PTCE 95-60,  (e) we have not, nor has anyone
acting on our behalf offered,  transferred,  pledged, sold or otherwise disposed of the Certificates,  any interest in the Certificates
or any  other  similar  security  to,  or  solicited  any  offer to buy or  accept a  transfer,  pledge  or  other  disposition  of the
Certificates,  any interest in the Certificates or any other similar security from, or otherwise  approached or negotiated with respect
to the  Certificates,  any interest in the  Certificates  or any other similar  security  with,  any person in any manner,  or made any
general  solicitation  by means of general  advertising  or in any other  manner,  or taken any other action,  that would  constitute a
distribution of the  Certificates  under the Act or that would render the  disposition of the  Certificates a violation of Section 5 of
the Act or require  registration  pursuant  thereto,  nor will act, nor has  authorized  or will  authorize  any person to act, in such
manner with respect to the Certificates,  (f) we are not a "U.S.  person" within the meaning of Regulation S under the Act (a "Non-U.S.
Person"),  (g) we are aware that the sale to us is being made in reliance on Regulation  S, and (h) we are  acquiring the  Certificates
for our own account or for resale  pursuant  to  Regulation  S under the Act and  further,  understand  that such  Certificates  may be
resold,  pledged or transferred only (A) to a person reasonably  believed to be a qualified  institutional buyer that purchases for its
own  account or for the  account of a qualified  institutional  buyer to whom  notice is given that the  resale,  pledge or transfer is
being made in  reliance on Rule 144A,  (B) to a Non-U.S.  Person in  accordance  with  Regulation  S under the Act or  (C) pursuant  to
another exemption from registration under the Act.

                                                     Very truly yours,

                                                               EXHIBIT N

                                              FORM OF TRANSFEREE AFFIDAVIT AND AGREEMENT

STATE OF              )
                           : ss.:
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 Trust  Administrator  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 Series  Supplement  dated as of  ___________________  and the  Standard  Terms of Pooling and
Servicing  Agreement dated  February 1,  2007  (collectively,  the "Agreement") by and among the Depositor,  the Seller(s),  the Master
Servicer,  the Trust  Administrator,  the Special  Servicer,  the Modification  Oversight Agent, the Trustee and the Servicers that are
party to the Series  Supplement,  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  and the Trust
Administrator  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  attached,  attested  by its  [Assistant]
Secretary, this ____ day of ___________.

                  Re:      [_________________________] Mortgage Backed Pass Through Certificates, Series 200_ ___, 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 Series  Supplement  dated as of  ___________________  and the Standard Terms of Pooling and Servicing
Agreement dated February 1,  2007 (collectively,  the "Agreement") by and among the Depositor,  the Seller(s), the Master Servicer, the
Trust  Administrator,  the Special  Servicer,  the  Modification  Oversight  Agent, the Trustee and the Servicers that are party to the
Series  Supplement.  All terms used herein and not  otherwise  defined shall have the meanings set forth in the  Agreement.  The Seller
hereby certifies, represents and warrants to, and covenants with, the Depositor, the Trust Administrator 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 Trust  Administrator a transfer affidavit and
agreement in the form  attached to the  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,

                  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)     No Mortgage Loan is 30 days or more  contractually  delinquent in payment and there are no material defaults
                           under the terms of any Mortgage Loan;

                  (iii)    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;

                  (iv)     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;

                  (v)      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;

                  (vi)     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 4.09 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 4.09 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;

                  (vii)    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;

                  (viii)   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;

                  (ix)     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;

                  (x)      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;

                  (xi)     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;

                  (xii)    All  improvements  subject to the Mortgage which were  considered in determining  the appraised value of the

                           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

                           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;

                  (xiii)   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;

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

                           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

                           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

                  (xviii)  With respect to each Mortgage Loan sold by any Seller,  to the knowledge of DLJMC,  (i) no borrower obtained
