      Class C-B-6  and Class C-B-7  Certificates  is 5.0645% per annum.  After
      such  Distribution  Date,  the  Pass-Through  Rate for each of the Class
      C-B-1, Class C-B-2,  Class C-B-3,  Class C-B-4, Class C-B-5, Class C-B-6

(15)  The  Class 7-X  Certificates  will not accrue  interest  on their  Class
      Principal  Balance.  With the exception of the first  Distribution  Date
      (as provided in footnote 23 below),  the Class 7-X  Certificates  accrue
      interest on the Class 7-X Notional Amount.
(16)  The  Class 7-X  Certificates  will be comprised of two REMIC IV  regular
      interests,  a principal only regular interest  designated  7-X-PO and an
      interest  only  regular  interest  designated  7-X-IO,   which  will  be
      entitled to  distributions  as set forth  herein.  On each  Distribution
      Date,  the  Class 7-X  Certificates  shall be entitled to the  Class 7-X
      Distributable  Amount.  With respect to any Distribution  Date after the
      first distribution date, interest accrued on the Class 7-X  Certificates
      during the related  Accrual  Period shall equal  interest at the related
      Pass-Through Rate on the Class 7-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.   The  Pass-Through   Rate  for  the  Class 7-X
      Certificates   or  the  REMIC IV   Regular   Interest   7-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 (vi) 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 III  Regular  Interests  LT1,
      LT2, LT3, LT4,  LT5, LT6, LT7, LT8,  LT-Y7A and LT-Y7B.  For purposes of
      calculating the Pass-Through  Rate for the Class 7-X  Certificates,  the
      numerator is equal to the sum of the following components:
            (i)   the  Uncertificated  Pass-Through Rate for REMIC III Regular
                  Interests  LT1 and LT-Y7A minus the Marker Rate,  applied to
                  a  notional  amount  equal to the  aggregate  Uncertificated
                  Principal  Balance of REMIC III  Regular  Interests  LT1 and
                  LT-Y7A;
            (ii)  the  Uncertificated  Pass-Through Rate for REMIC III Regular
                  Interest  LT2 minus the Marker  Rate,  applied to a notional
                  amount  equal to the  Uncertificated  Principal  Balance  of
                  REMIC III Regular Interest LT2;
            (iii) the  Uncertificated  Pass-Through Rate for REMIC III Regular
                  Interest  LT4 minus  twice the  Marker  Rate,  applied  to a
                  notional  amount  equal  to  the  Uncertificated   Principal
                  Balance of REMIC III Regular Interest LT4;
            (iv)  the  Uncertificated  Pass-Through Rate for REMIC III Regular
                  Interests  LT5 and LT-Y7B minus the Marker Rate,  applied to
                  a  notional  amount  equal to the  aggregate  Uncertificated
                  Principal  Balance of REMIC III  Regular  Interests  LT1 and
                  LT-Y7B;
            (v)   the  Uncertificated  Pass-Through Rate for REMIC III Regular
                  Interest  LT6 minus the Marker  Rate,  applied to a notional
                  amount  equal to the  Uncertificated  Principal  Balance  of
                  REMIC III Regular Interest LT2; and
            (vi)  the  Uncertificated  Pass-Through Rate for REMIC III Regular
                  Interest  LT8 minus  twice the  Marker  Rate,  applied  to a
                  notional  amount  equal  to  the  Uncertificated   Principal
                  Balance of REMIC III Regular Interest LT4.
      Accrued  interest  on the  Class 7-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 7  Certificates  in
      respect   of  Basis  Risk   Shortfalls   from  the   Group 7   Available
      Distribution  Amount shall be deemed to have first been distributed from
      REMIC IV to the holders of the Class 7-X  Certificates in respect of the
      Class 7-X-IO  REMIC IV Regular Interest and then paid by such holders to
      such Class of Group 7 Certificates.
(17)  The   Class 7-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.
(18)  The Class P  Certificates will not have a Class Principal Balance,  will
      be entitled to  distributions of Assigned  Prepayment  Premiums only and
      such  entitlement  shall  not  be  an  interest  in  any  REMIC  created
      hereunder.
(19)  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.
(20)  The  Class  AR  Certificates  are not  themselves  issued  by  REMIC IV,
      instead,  the Class AR  Certificates  will  represent  ownership  of two
      REMIC  residual  interests -  Component I  of the Class AR (which is the
      residual  interest in REMIC III) and Component II of the Class AR (which
      is the residual interest in REMIC IV).
(21)  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 IV  corresponding  to such
Certificate as part of the payment made to the Class 7-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 IV 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.

the Seller to the Trustee in  accordance  with this  Agreement for the benefit
of the  Certificateholders  by including (or deleting, in the case of Mortgage
Loans which are  repurchased or substituted in accordance with this Agreement)
the information  required by the MERS® System to (a) identify  the Trustee and
(b) identify  the series of the  Certificates  issued in connection  with such
Mortgage  Loans.  The  Trustee  shall  confirm,  or  cause  the  Custodian  to
confirm,  on the Final Certification of the Custodian that such assignment has

Servicer  to, and each  related  Servicer  agrees that it will not,  alter the
information  referenced  in this  paragraph  with respect to any Mortgage Loan
during  the term of this  Agreement  unless and until  such  Mortgage  Loan is
repurchased or substituted in accordance with the terms of this Agreement.

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

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

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

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

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

(d)   It is the  express  intent of the  parties  to this  Agreement  that the
conveyance  of the Mortgage  Loans by the Depositor to the Trustee as provided
in this  Section 2.01 be, and be construed as, a sale of the Mortgage Loans by
the  Depositor  to the  Trustee.  It is,  further,  not the  intention  of the
parties  to this  Agreement  that  such  conveyance  be deemed a pledge of the
Mortgage  Loans by the  Depositor  to the  Trustee  to  secure a debt or other
obligation of the Depositor.  However, in the event that,  notwithstanding the
intent of the parties to this  Agreement,  the  Mortgage  Loans are held to be
the property of the  Depositor,  or if any for any other reason this Agreement
is held or deemed to create a security  interest  in the  Mortgage  Loans then
(a) this Agreement shall also be deemed to be a security  agreement within the
meaning of Articles 8 and 9 of the New York Uniform  Commercial  Code; (b) the
conveyance  provided for in this Section 2.01 shall be deemed to be a grant by
the  Depositor to the Trustee for the benefit of the  Certificateholders  of a
security interest in all of the Depositor's  right,  title and interest in and
to the Mortgage  Loans and all amounts  payable to the holders of the Mortgage
Loans  in  accordance   with  the  terms  thereof  and  all  proceeds  of  the
conversion,   voluntary  or   involuntary,   of  the   foregoing   into  cash,
instruments,  securities or other property,  including without  limitation all
amounts,  other than investment  earnings,  from time to time held or invested
in  the  Certificate  Account,  whether  in the  form  of  cash,  instruments,
securities  or  other  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)   Except  as  specifically  set  forth in this  Agreement  or by  separate
written  agreement  among the  related  parties  hereto,  the  Depositor,  the
Seller,  each Servicer and the Master  Servicer  agree that the  provisions of
this Agreement  shall  supercede any provisions in any existing  mortgage loan
purchase  agreement or servicing  agreement with respect to the Mortgage Loans
for which the Depositor,  the Seller, a Servicer or the Master Servicer may be
a party.

SECTION 2.02.     Acceptance by the Trustee.

(a)   Pursuant to Section 4 of the LaSalle Custodial Agreement,  the Custodian
agrees to  execute  and  deliver on the  Closing  Date to the  Depositor,  the
Trustee and the Trust Administrator a Trust Receipt and Initial  Certification
in  the  form  annexed  hereto  as  Exhibit I-1.   Based  on  its  review  and
examination,  and only as to the  documents  identified  in such Trust Receipt
and Initial  Certification,  the Custodian  acknowledges  that such  documents
appear  regular on their face and relate to such Mortgage  Loan. The Custodian
shall be under no duty or  obligation  to  inspect,  review  or  examine  said
documents,  instruments,  certificates  or other papers to determine  that the
same are genuine,  enforceable or appropriate for the  represented  purpose or
that they have actually been recorded in the real estate  records or that they
are other than what they purport to be on their face.

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

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

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

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

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

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

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

(a)   Each of DLJMC,  in its capacity as Seller,  Wells Fargo, in its capacity
as  Master  Servicer,  WMMSC,  in its  capacity  as a  Servicer,  SPS,  in its
capacity as Servicer, U.S. Bank, in its capacity as Servicer,  Wells Fargo, in
its capacity as Servicer  and  Wilshire,  in its capacity as Special  Servicer
hereby makes the representations and warranties  applicable to it set forth in
Schedule IIA, IIB,  IIC,  IID, IIE, IIF or IIG, as applicable  hereto,  and by
this reference  incorporated  herein,  to the  Depositor,  the Trustee and the
Trust  Administrator,  as of the Closing Date, or if so specified therein,  as
of the Cut off  Date or such  other  date as may be  specified.  In  addition,
SPS, in its  capacity as Servicer,  Wells  Fargo,  in its capacity as Servicer
and Wilshire,  in its capacity as Special  Servicer makes the  representations
and  warranties  applicable  to it set forth in Schedule IID, IIE, IIF and IIG
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;   provided  that,  if  applicable,   any  breach  of  the
representations  and  warranties  set forth in Schedule  III(xix),  III(xxii),
III(xxiv), III(xxvii),  III(xxviii),  III(xxix) and III(xxxii) shall be deemed
to materially and adversely affect the interests of the  Certificateholders in
that Mortgage  Loan.  The Seller hereby  covenants  that within 90 days of the
earlier of its discovery or its receipt of written  notice from any party of a
breach  of  any   representation   or   warranty   made  by  it   pursuant  to
Section 2.03(b)  which  materially and adversely  affects the interests of the
Certificateholders  in any Mortgage  Loan sold by the Seller to the Trust,  it
shall cure such breach in all material respects,  and if such breach is not so
cured,  shall,  (i) if  such  90  day  period  expires  prior  to  the  second
anniversary  of the  Closing  Date,  remove  such  Mortgage  Loan (a  "Deleted
Mortgage  Loan") from the Trust Fund and  substitute  in its place a Qualified
Substitute  Mortgage  Loan,  in the manner and subject to the  conditions  set
forth in this  Section;  or (ii)  repurchase  the  affected  Mortgage  Loan or
Mortgage Loans at the Purchase Price in the manner set forth below;  provided,
however,  that  any such  substitution  pursuant  to (i)  above  shall  not be
effected prior to the delivery to the Trustee and the Trust  Administrator  of
the Opinion of Counsel required by Section 2.05  hereof,  if any, and any such
substitution  pursuant  to (i)  above  shall  not  be  effected  prior  to the
additional  delivery  to the Trustee or the Trust  Administrator  of a Request
for Release  substantially  in the form of  Exhibit K  relating to the Deleted
Mortgage  Loan  and the  Mortgage  File  for  any  such  Qualified  Substitute
Mortgage  Loan.  The Seller shall  promptly  reimburse the Trustee,  the Trust
Administrator,  the  Special  Servicer  and  the  related  Servicer  (if  such
Servicer  is not the  Seller  of such  Mortgage  Loan) for any  actual  out of
pocket expenses reasonably incurred by the Trustee,  the Trust  Administrator,
the Special  Servicer and the related  Servicer  (if such  Servicer is not the
Seller of such  Mortgage  Loan) in respect of enforcing  the remedies for such
breach.  With respect to any representation  and warranties  described in this
Section which  are  made  to the  best  of  the  Seller's  knowledge  if it is
discovered  by any of the  Depositor,  the Master  Servicer,  the Seller,  any
Servicer,  the Special Servicer,  the Trustee or the Trust  Administrator that
the  substance  of such  representation  and warranty is  inaccurate  and such
inaccuracy  materially and adversely affects the value of the related Mortgage
Loan or the interests of the Certificateholders  therein,  notwithstanding the
Seller's   lack  of  knowledge   with   respect  to  the   substance  of  such
representation  or warranty,  such inaccuracy  shall be deemed a breach of the
applicable representation or warranty.

            With respect to any Qualified  Substitute  Mortgage Loan or Loans,
the  Seller  shall   deliver  to  the   Custodian   for  the  benefit  of  the
Certificateholders  the Mortgage Note, the Mortgage, the related assignment of
the  Mortgage,  and such other  documents  and  agreements  as are required by
Section 2.01(b),  with the Mortgage Note endorsed and the Mortgage assigned as
required by  Section 2.01.  No  substitution  is  permitted  to be made in any
calendar  month  after  the  Determination  Date  for  such  month.  Scheduled
Payments due with respect to Qualified  Substitute Mortgage Loans in the month
of  substitution  shall not be part of the Trust Fund and will be  retained by
the  Seller  on the  next  succeeding  Distribution  Date.  For the  month  of
substitution,  distributions  to  Certificateholders  will include the monthly
payment due on any Deleted  Mortgage  Loan for such month and  thereafter  the
Seller  shall be entitled  to retain all  amounts  received in respect of such
Deleted  Mortgage  Loan. The Seller shall amend the Mortgage Loan Schedule for
the benefit of the  Certificateholders  to reflect the removal of such Deleted
Mortgage Loan and the substitution of the Qualified  Substitute  Mortgage Loan
or Loans and the Seller shall  deliver the amended  Mortgage  Loan Schedule to
the  Trustee,   the   Servicers  and  the  Trust   Administrator.   Upon  such
substitution,  the  Qualified  Substitute  Mortgage  Loan or  Loans  shall  be
subject to the terms of this  Agreement in all respects,  and the Seller shall
be deemed to have made with  respect  to such  Qualified  Substitute  Mortgage
Loan  or  Loans,  as of the  date of  substitution,  the  representations  and
warranties  made  pursuant to  Section 2.03(b)  with respect to such  Mortgage
Loan.  Upon any such  substitution  and the deposit to the Collection  Account
of the  amount  required  to be  deposited  therein  in  connection  with such
substitution  as  described  in the  following  paragraph,  the Trustee  shall
instruct the  Custodian  to release the Mortgage  File held for the benefit of
the  Certificateholders  relating to such Deleted  Mortgage Loan to the Seller
and the  Trustee  shall  execute and deliver at the  Seller's  direction  such
instruments  of transfer or  assignment  prepared by the Seller,  in each case
without  recourse,  as shall be necessary to vest title in the Seller,  or its
designee,  the Trustee's interest in any Deleted Mortgage Loan substituted for
pursuant to this Section 2.03.

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

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

            In the event that the Seller  shall be  required to  repurchase  a
Mortgage Loan pursuant to this  Agreement,  the Purchase  Price therefor shall
be  deposited  in  the  Collection  Account  on or  before  the  Business  Day
immediately  preceding the Distribution  Date in the month following the month
during which the Seller  became  obligated  hereunder to repurchase or replace
such Mortgage Loan and upon such deposit of the Purchase  Price,  the delivery
of the  Opinion  of Counsel  if  required  by  Section 2.05  and  receipt of a
Request for  Release in the form of  Exhibit K  hereto,  the  Custodian  shall
release   the   related   Mortgage   File   held  for  the   benefit   of  the
Certificateholders  to such Person,  and the Trustee shall execute and deliver
at  such  Person's  direction  such  instruments  of  transfer  or  assignment
prepared by such Person, in each case without recourse,  as shall be necessary
to  transfer  title from the  Trustee.  It is  understood  and agreed that the
obligation  under  this  Agreement  of  any  Person  to  cure,  repurchase  or
substitute  any  Mortgage  Loan  as to  which a  breach  has  occurred  and is
continuing  shall  constitute the sole remedy against such Persons  respecting
such breach  available to  Certificateholders,  the Depositor,  the Trustee or
the Trust Administrator on their behalf.

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

            Notwithstanding  the  foregoing,  the  substitution  of a  Deleted
Mortgage Loan that is a WMMSC  Serviced  Mortgage Loan or the  repurchase of a
Mortgage  Loan that is a WMMSC  Serviced  Mortgage Loan by the Seller shall be
subject  to,  and  shall in no way  adversely  affect,  the  right of WMMSC to
continue  servicing and collecting its Servicing Fee for such Deleted Mortgage
Loan or Mortgage Loan, as applicable.

            (d)   If any Mortgage Loan becomes 60 days or more  delinquent and
remains 60 days or more  delinquent on January 31, 2005, then the Seller shall
be deemed to have  automatically  breached the representation and warranty set
forth in clause (iii) of Schedule III hereto;  provided,  however,  that in no
event shall such  representation  and warranty be automatically  breached with
respect to Mortgage Loans  constituting  more than 1% of the aggregate Cut-off
Date Principal Balance of the Mortgage Loans. The related  Servicer,  if other
than  Wells  Fargo  Bank,  N.A.,  shall  notify the Trust  Administrator,  the
Seller,  the Master  Servicer and the Trustee of any such  delinquency  and if
the related  Servicer is Wells Fargo Bank,  N.A., Wells Fargo Bank, N.A. shall
notify the Trust  Administrator and the Trust  Administrator shall forward any
such  notice  to  the  Seller,  the  Master  Servicer  and  the  Trustee.   In
connection  with any such  delinquency  and automatic  breach  relating to the
Mortgage  Loans  constituting  not more than 1% of the aggregate  Cut-off Date
Principal  Balance of the  Mortgage  Loans,  the Seller  shall be  required to
repurchase  or replace  all such  delinquent  Mortgage  Loans  with  Qualified
Substitute  Mortgage  Loans in  accordance  with the terms and  provisions  of
Section  2.03(c)  on or  before  February  9,  2005  (without  regard  to  any
reference  in Section  2.03(c) to a "90-day"  period).  A breach may exist for
purposes  of  Section  2.03(c),   notwithstanding   the  non-existence  of  an
automatic breach for purposes of this Section 2.03(d).

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

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

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

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

            Notwithstanding  any  contrary  provision  of this  Agreement,  no
substitution  pursuant to  Section 2.02  shall be made more than 90 days after
the  Closing  Date  unless the Seller  delivers  to the  Trustee and the Trust
Administrator an Opinion of Counsel,  which Opinion of Counsel shall not be at
the expense of any of the Trustee,  the Trust Administrator or the Trust Fund,
addressed to the Trustee and the Trust Administrator,  to the effect that such
substitution  will not (i) result in the  imposition of the tax on "prohibited
transactions"  on the Trust Fund or  contributions  after the Startup Date, as
defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively,  or (ii)
cause each REMIC  created  hereunder to fail to qualify as a REMIC at any time
that any Certificates are outstanding.

SECTION 2.06.     Issuance of Certificates.

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

SECTION 2.07.     REMIC Provisions.

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

(b)   The Trust  Administrator  shall act as the "tax matters  person" (within
the meaning of the REMIC Provisions) for each REMIC created hereunder,  in the
manner provided under Treasury  regulations  section 1.860F 4(d) and temporary
Treasury  regulations  section  301.6231(a)(7)  1T. In the event  that for any
reason,  the Trust  Administrator  is not recognized as the tax matters person
then the  Trust  Administrator  shall act as agent  for the  Class AR  and the
Class AR-L  Certificateholder  as tax matters  person.  By its acceptance of a
Class AR or Class AR-L  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 Class AR or Class AR-L 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 Class AR or Class AR-L  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
Class AR or Class AR-L  Certificate  such  information as is necessary for the
application  of any tax relating to the  transfer of a Class AR or  Class AR-L
Certificate  to any  Person  who is not a  permitted  transferee,  (ii) to the
Certificateholders  such information or reports as are required by the Code or
the REMIC Provisions  including  reports relating to interest,  original issue
discount  and market  discount  or premium and (iii) to the  Internal  Revenue
Service the name,  title,  address and telephone number of the person who will
serve as the representative of each REMIC created hereunder.

(f)   The  Trustee,  to the extent  directed by the Trust  Administrator,  the
Depositor  and the Holder of the  Class AR or  Class AR-L  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 Class AR or Class AR-L  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  Class AR  or   Class AR-L
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).  However, in the case of WMMSC, the prompt deposit of any
such  amount  in the  Certificate  Account  shall  cure any  Special  Event of
Default  unless notice of such Special Event of Default is  accompanied  by an
Opinion  of  Counsel,  at the  expense  of  WMMSC,  to  the  effect  that  the
cumulative effect of WMMSC's breach or breaches,  notwithstanding  the deposit
of the amounts of any such tax,  shall have given rise to a  substantial  risk
that any REMIC created hereunder would fail to continue to qualify as a REMIC.

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

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

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

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

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

(m)   In order to enable the Trust  Administrator to perform its duties as set
forth herein,  the  Depositor  shall  provide,  or cause to be provided to the
Trust  Administrator,  within ten days after the Closing Date, all information
or data the Trust Administrator  determines to be relevant for tax purposes to
the valuations and offering  prices of the  Certificates,  including,  without
limitation,  the price, yield,  prepayment assumption and projected cash flows
of the Certificates and the Mortgage Loans and the Trust  Administrator  shall
be  entitled  to rely  upon  any  and all  such  information  and  data in the
performance of its duties set forth herein.  Thereafter,  the Master Servicer,
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  Serviced  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
Class 7-A-1-1,    Class 7-A-1-2,    Class 7-A-2,   Class 7-M-1,   Class 7-M-2,
Class 7-M-3 and Class 7-M-4  Certificateholders to receive payments in respect
of Basis Risk  Shortfalls as rights in an interest  rate cap contract  written
by  the   Class 7-X   Certificateholders   in  favor  of  the   Class 7-A-1-1,
Class 7-A-1-2,   Class 7-A-2,   Class 7-M-1,   Class 7-M-2,   Class 7-M-3  and
Class 7-M-4  Certificateholders  and not as an obligation  of REMIC IV,  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 IV  shall be treated as a  distribution  to the Class 7-X
Certificates.  In addition, the Class 7-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 7-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 IV
pursuant  to  Section 4.01(II)(d)(xiii)  (which  amounts  are  expected  to be
zero).  Thus  each  Class 7-A-1-1,  Class 7-A-1-2,  Class 7-A-2,  Class 7-M-1,
Class 7-M-2,  Class 7-M-3  and  Class 7-M-4  Certificate  shall be  treated as
representing  ownership  of not  only  REMIC IV  regular  interests,  but also
ownership  of an interest in an interest  rate cap  contract.  Each  Class 7-X
Certificate   shall  represent  an  obligation  under  an  interest  rate  cap
contract.  For  purposes of  determining  the issue price of REMIC IV  regular
interests,  the Trust  Administrator  shall assume that the interest  rate cap
contract has a value of $5,000.

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

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

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

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

                                  ARTICLE III

                         ADMINISTRATION AND SERVICING
                              OF MORTGAGE LOANS

SECTION 3.01.     Servicers to Service Mortgage Loans.

            For  and on  behalf  of  the  Certificateholders,  as  independent
contractors of the Trust, (i) each Servicer,  severally and not jointly, shall
service  and   administer  the  related   Non-Designated   Mortgage  Loans  in
accordance  with the  terms of this  Agreement  and  with  Accepted  Servicing
Practices,  (ii) the Master Servicer shall, in accordance with Section 3.03 of
this  Agreement,  master service and administer  the  Non-Designated  Mortgage
Loans  (other  than the  WMMSC  Serviced  Mortgage  Loans) by  overseeing  and
enforcing the servicing of the  Non-Designated  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 3.22 of this
Agreement,  master service and  administer  the  Designated  Mortgage Loans by
overseeing  and enforcing the servicing of the  Designated  Mortgage  Loans by
the  related  Designated  Servicer  according  to the  terms  of  the  related
Designated  Servicing  Agreement.  The  obligations of each of SPS, U.S. Bank,
Wells Fargo and WMMSC  hereunder to service and  administer the Mortgage Loans
shall be limited to the SPS Serviced  Mortgage  Loans,  the U.S. Bank 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 SPS Serviced  Mortgage Loans (and the related proceeds
thereof  and  related  REO  Properties)  in the  case of SPS,  the  U.S.  Bank
Serviced  Mortgage  Loans (and the  related  proceeds  thereof and related REO
Properties) in the case of U.S. Bank, 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  Non-Designated  Mortgage Loans shall be limited to
the Wells Fargo Serviced  Mortgage Loans, the SPS Serviced Mortgage Loans, the
U.S. Bank Serviced  Mortgage Loans and the Special  Serviced  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  Subservicers as provided in Section 3.02 hereof, to do or cause to be
done any and all things that it may deem  necessary or desirable in connection
with such  servicing  and  administration,  including  but not limited to, the
power and  authority,  subject to the terms hereof (i) to execute and deliver,
on behalf of the  Certificateholders  and the  Trust,  customary  consents  or
waivers and other  instruments and documents,  (ii) to consent to transfers of
any  Mortgaged  Property and  assumptions  of the  Mortgage  Notes and related
Mortgages  (but  only in the  manner  provided  in this  Agreement),  (iii) to
collect any Insurance  Proceeds and other  Liquidation  Proceeds,  and (iv) to
effectuate  foreclosure or other  conversion of the ownership of the Mortgaged
Property  securing  any  Mortgage  Loan;  provided  that  neither  the  Master
Servicer  nor a Servicer  shall take any action that is  inconsistent  with or
prejudices  the interests of the Trust Fund or the  Certificateholders  in any
Mortgage Loan or the rights and interests of the Depositor,  the Trustee,  the
Trust  Administrator  or the  Certificateholders  under  this  Agreement.  The
Master  Servicer and each Servicer  shall  represent and protect the interests
of the Trust  Fund in the same  manner as it  protects  its own  interests  in
mortgage  loans in its own  portfolio in any claim,  proceeding  or litigation
regarding  a Mortgage  Loan,  and shall not make or permit  any  modification,
waiver or amendment of any  Mortgage  Loan that would cause any REMIC  created
hereunder  to fail to  qualify as a REMIC or result in the  imposition  of any
tax under  Section 860F(a)  or  Section 860G(d)  of the Code. Without limiting
the generality of the  foregoing,  the Master  Servicer and each Servicer,  in
its own  name or in the  name  of the  Depositor  and  the  Trust,  is  hereby
authorized  and  empowered  by  the   Depositor,   the  Trust  and  the  Trust
Administrator,   when  the  Master  Servicer  or  such  Servicer  believes  it
appropriate in its reasonable  judgment,  to execute and deliver, on behalf of
the  Trust,  the  Trustee,  the  Trust  Administrator,   the  Depositor,   the
Certificateholders  or any of them, any and all instruments of satisfaction or
cancellation,  or of  partial  or full  release  or  discharge  and all  other
comparable  instruments,  with respect to the Mortgage Loans, and with respect
to the Mortgaged  Properties  held for the benefit of the  Certificateholders.
The  Master  Servicer  and each  Servicer  shall  prepare  and  deliver to the
Depositor  and/or the Trustee  and/or the Trust  Administrator  such documents
requiring  execution  and delivery by either or both of them as are  necessary
or  appropriate  to enable  the Master  Servicer  or such  Servicer  to master
service and  administer  or service and  administer  the  Mortgage  Loans,  as
applicable,  to the extent that the Master  Servicer  or such  Servicer is not
permitted  to execute and deliver  such  documents  pursuant to the  preceding
sentence.  Upon receipt of such  documents,  the Depositor  and/or the Trustee
or the Trust  Administrator  shall execute such  documents and deliver them to
the Master Servicer or such Servicer.

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

            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 as specifically  provided in the related Servicer Letter Agreement.  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 to the contrary in this Agreement,  with
respect to any action which  according to the terms of this Agreement is to be
performed by the Master  Servicer  and the  applicable  Servicer,  (i) if such
action  relates to a WMMSC Serviced  Mortgage  Loan,  only WMMSC shall have an
obligation  to  perform  such  action,  and (ii) if such  action  relates to a
Mortgage  Loan  which  is not a WMMSC  Serviced  Mortgage  Loan,  the  related
Servicer  shall have an  obligation  to perform  such  action,  and the Master
Servicer in its capacity as successor  servicer  shall also have an obligation
to perform such action, but only if the related Servicer fails to do so.

            Notwithstanding  anything in this  Agreement to the contrary,  (i)
the  purchase  of any WMMSC  Serviced  Mortgage  Loan by any  Person  shall be
subject  to the rights of WMMSC to  continue  servicing  such  WMMSC  Serviced
Mortgage Loan for the same Servicing Fee  substantially in accordance with the
terms of this Agreement,  (ii) the purchase of any U.S. Bank Serviced Mortgage
Loan by any Person  shall be subject  to the rights of U.S.  Bank to  continue
servicing  such U.S.  Bank Serviced  Mortgage Loan for the same  Servicing Fee
substantially  in  accordance  with the terms of this  Agreement and (iii) the
purchase  of any Wells Fargo  Serviced  Mortgage  Loan by any Person  shall be
subject to the rights of Wells  Fargo to continue  servicing  such Wells Fargo
Serviced  Mortgage Loan for the same Servicing Fee substantially in accordance
with the terms of this Agreement.

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

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

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

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

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

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

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

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

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

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

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

(e)   The Special  Servicer is hereby  authorized to enter into a financing or
other  facility  (any such  arrangement,  a  "Facility")  under  which (i) the
Special  Servicer  assigns or pledges to another  person (a "Lender")  (A) the
Special  Servicer's  rights  under this  Agreement  to be  reimbursed  for any
Advances  or  Servicing  Advances,  and (B) any and all rights of the  Special
Servicer   under  this  Agreement   resulting  from  the  Special   Servicer's
performance  of its  obligations  under  this  Agreement,  including,  without
limitation,  any Servicing Fees, interest income,  Ancillary Income, and other
payments  received by the Special  Servicer for servicing  the Mortgage  Loans
and (ii) the  Lender  agrees to fund  some or all  Advances  and/or  Servicing
Advances  required  to be  made  by the  Special  Servicer  pursuant  to  this
Agreement.    No    consent    of   the    Trustee,    Trust    Administrator,
Certificateholders  or any other party is required before the Special Servicer
may enter into a Facility;  provided,  however,  that the consent of the Trust
Administrator  shall be required  before the Special  Servicer may cause to be
outstanding  at  one  time  more  than  one  Facility.   Notwithstanding   the
existence  of any  Facility,  the  Special  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 the Special  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,  U.S. Bank and SPS to
service and  administer  the Wells Fargo Serviced  Mortgage  Loans,  U.S. Bank
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 Wells Fargo,  U.S.  Bank and SPS 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 Wells Fargo,  U.S. Bank and SPS
and shall cause each of Wells Fargo,  U.S. Bank and SPS to perform and observe
the covenants,  obligations and conditions to be performed or observed by such
Servicer under this Agreement.

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

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

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

            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  (i) waive any late payment charge or any
prepayment  charge or penalty  interest in connection with the prepayment of a
Non-Designated  Mortgage  Loan and (ii) extend the Due Dates for  payments due
on a Mortgage Note for a period not greater than 180 days; provided,  however,
that no such  Servicer  can extend  the  maturity  of any such  Non-Designated
Mortgage  Loan past the date on which the final  payment  is due on the latest
maturing  Mortgage  Loan as of the  Cut-off  Date.  In the  event  of any such
arrangement,   the  related  Servicer  shall  make  Advances  on  the  related
Non-Designated   Mortgage   Loans  in  accordance   with  the   provisions  of
Section 5.01  during the scheduled  period in accordance with the amortization
schedule of such Mortgage Loan without  modification thereof by reason of such
arrangements.   No  Servicer  shall  be  required  to  institute  or  join  in
litigation  with  respect  to  collection  of any  payment  (whether  under  a
Mortgage,  Mortgage  Note or otherwise  or against any public or  governmental
authority with respect to a taking or condemnation) if it reasonably  believes
that enforcing the provision of the Mortgage or other  instrument  pursuant to
which such payment is required is prohibited by applicable law.

(b)   Each Servicer shall  segregate and hold all funds collected and received
pursuant to a Non-Designated  Mortgage Loan separate and apart from any of its
own funds and general  assets and shall  establish  and  maintain  one or more
Collection  Accounts,  in the form of time deposit or demand accounts,  titled
"[Servicer's  name],  in trust for the  Holders of  Adjustable  Rate  Mortgage
Trust  2004-5,  Adjustable  Rate  Mortgage-Backed  Pass-Through  Certificates,
Series  2004-5" or, if  established  and maintained by a Subservicer on behalf
of a  Servicer,  "[Subservicer's  name],  in trust for  [Servicer's  name]" or
"[Subservicer's  name],  as agent,  trustee  and/or  bailee of  principal  and
interest  custodial account for [Servicer's name], its successors and assigns,
for various owners of interest in  [Servicer's  name]  mortgage-backed  pools.
In the event that a Subservicer employs a subservicer,  the Collection Account
shall  be  titled  "[name  of   Subservicer's   subservicer],   in  trust  for
[Subservicer's  name]." Each  Collection  Account  maintained by each Servicer
(other than Wells  Fargo),  shall be an  Eligible  Account  acceptable  to the
Depositor and the Trust  Administrator.  Each Collection Account maintained by
Wells Fargo shall be an Eligible  Account.  Funds  deposited  in a  Collection
Account  may  be  drawn  on  by  the  related   Servicer  in  accordance  with
Section 3.08.  Any funds  deposited  in a  Collection  Account  (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,  unless otherwise  indicated,  and retain therein,  the following
collections  remitted by  Subservicers  or payments  received by such Servicer
and payments made by such Servicer  subsequent to the Cut-off Date, other than
payments of principal and interest due on or before the Cut-off Date:

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

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

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

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

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

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

(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 (ii) with respect
to each  Non-Designated  Mortgage  Loan  covered  by a  Lender  Paid  Mortgage
Guaranty  Insurance  Policy,  any amounts required to effect timely payment of
the  premiums  on  such  Mortgage   Guaranty   Insurance  Policy  pursuant  to
Section 3.09(c).  In the event  that a  Servicer  shall  remit any  amount not
required  to  be  remitted,  it  may  at  any  time  withdraw  or  direct  the
institution  maintaining  the  related  Collection  Account to  withdraw  such
amount from such  Collection  Account,  any  provision  herein to the contrary
notwithstanding.   Such   withdrawal  or  direction  may  be  accomplished  by
delivering  written  notice  thereof to the Trustee or such other  institution
maintaining such Collection  Account which describes the amounts  deposited in
error in such  Collection  Account.  Each  Servicer  shall  maintain  adequate
records with respect to all  withdrawals  made by it pursuant to this Section.
All funds  deposited  in a Collection  Account  shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.08(a).

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

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

(ii)  any  amount   deposited   by  the  Trust   Administrator   pursuant   to
      Section 3.05(e) in connection with any 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 3.22(b);

(iv)  all Advances remitted by the Master Servicer to the Trust  Administrator
      pursuant to Section 5.01 and Section 3.22(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  Certificate  holders until
disbursed in accordance  with this  Agreement or withdrawn in accordance  with
Section 3.08(b).  In no event shall the Trust  Administrator  incur  liability
for withdrawals  from the  Certificate  Account at the direction of the Master
Servicer or any Servicer.

(e)   Each  institution  at  which a  Collection  Account  or the  Certificate
Account is  maintained  shall either hold such funds on deposit  uninvested or

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

(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,  the  Capitalized  Interest  Account.  On the Closing Date
the  Depositor  shall  remit the  Capitalized  Interest  Deposit  to the Trust
Administrator  for  deposit  in  the  Capitalized  Interest  Account.  On  the
Business  Day  prior  to  the  January 2005   Distribution   Date,  the  Trust
Administrator  shall  transfer from the  Capitalized  Interest  Account to the
Certificate Account an amount equal to the Capitalized  Interest Deposit.  Any
funds  remaining in the Capitalized  Interest  Account  immediately  after the
January 2005 Distribution Date shall be paid to the Depositor.

                              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,

and  maintained  by a  Subservicer  on behalf of a  Servicer,  "[Subservicer's
name], in trust for  [Servicer's  name]" or  "[Subservicer's  name], as agent,
trustee   and/or  bailee  of  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 Subservicer

Subservicer's  subservicer]  in trust for  [Subservicer'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).

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

      to a  Non-Designated  Mortgage  Loan in accordance  with the  procedures

      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.

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

Trustee  and the Trust  Administrator  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 the
Master  Servicer or such  Servicer.  In  addition,  each  Servicer  other than

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
      compensation,  earnings on or investment income with respect to funds in

      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

      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 reimbursement  pursuant to this clause (A) with
      respect to any  Non-Designated  Mortgage  Loan being  limited to amounts
      received  on such  Non-Designated  Mortgage  Loan which  represent  late
      payments of principal and/or interest  (including,  without  limitation,
      Liquidation  Proceeds  and  Insurance  Proceeds  with  respect  to  such
      Mortgage  Loan)  respecting  which 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 withdraw  any amount  deposited  in such  Collection  Account and not
      required to be deposited therein;

(viii)      with respect to the  Non-Designated  Mortgage  Loans,  on the Cash
      Remittance  Date, to withdraw an amount equal to the portion of (a) with
      respect to the Group 1 Mortgage Loans,  Group 2 Mortgage Loans,  Group 3
      Mortgage  Loans,  Group 4  Mortgage  Loans,  Group 5  Mortgage Loans and
      Group 6 Mortgage Loans, the Available  Distribution  Amount and (b) with
      respect to the Group 7  Mortgage Loans, the Interest  Remittance  Amount
      and  Principal  Remittance  Amount,  in  each  case  applicable  to  the
      Mortgage Loans  serviced by such Servicer,  who will remit the aggregate
      of  such  amounts  to  the  Trust   Administrator  for  deposit  in  the
      Certificate Account;

(ix)  with respect to each  Non-Designated  Mortgage  Loan covered by a Lender

      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; and

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

            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.

(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  or the  Master  Servicer  any
      other  amounts  to  which  it or the  Master  Servicer  is  entitled  to
      reimbursement or payment under the terms of this 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
Mortgaged  Property  is located,  in an amount  which is at least equal to the
lesser  of (i)  the  replacement  value  of  the  improvements  securing  such
Non-Designated  Mortgage  Loan and  (ii) the  greater  of (A) the  outstanding
principal balance of such Non-Designated  Mortgage Loan and (B) an amount such
that the proceeds of such policy shall be  sufficient to prevent the Mortgagor
and/or the mortgagee from becoming a co insurer.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

(e)   The proceeds from any liquidation of a Non-Designated  Mortgage Loan, as
well as any  income  from a  related  REO  Property,  will be  applied  in the
following order of priority:  first, to reimburse the related Servicer for any
related  unreimbursed  Servicing  Advances  and  Servicing  Fees;  second,  to
reimburse such Servicer for any  unreimbursed  Advances;  third,  to reimburse
the related Collection  Account for any  Nonrecoverable  Advances (or portions
thereof)  that  were  previously   withdrawn  by  such  Servicer  pursuant  to
Section 3.08(a)(iii)  that  related  to  such  Non-Designated  Mortgage  Loan;
fourth,  to accrued  and unpaid  interest  (to the extent no Advance  has been
made  for  such  amount  or any  such  Advance  has  been  reimbursed)  on the
Non-Designated  Mortgage Loan or related REO  Property,  at the per annum rate
equal to the related Mortgage Rate reduced by the related  Servicing Fee Rate,
and any primary mortgage  guaranty  insurance fee rate, if applicable,  to the
Due Date  occurring  in the month in which such  amounts  are  required  to be
distributed;  and fifth,  as a recovery of  principal  of the  Mortgage  Loan.
Excess  proceeds,  if any, from the liquidation of a Liquidated  Mortgage Loan
("Excess  Proceeds") that is a  Non-Designated  Mortgage Loan will be retained
by the  related  Servicer as  additional  servicing  compensation  pursuant to
Section 3.14.

(f)   Each  Servicer  of the  Non-Designated  Mortgage  Loans  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 class of Subordinate
Certificates,  subject to each Rating Agency's acknowledgment that the Ratings
of the  Certificates  in effect  immediately  prior to the entering  into such
agreement   would  not  be   qualified,   downgraded   or  withdrawn  and  the
Certificates  would not be placed on credit review status (except for possible
upgrading)  as a result of such  agreement.  Any such  agreement  may  contain
provisions  whereby  such  Holder may (i)  instruct  the  related  Servicer to
commence  or  delay   foreclosure   proceedings  with  respect  to  delinquent
Non-Designated  Mortgage Loans and will contain  provisions for the deposit of
cash  with  such   Servicer  by  the  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 delinquent  Non-Designated  Mortgage Loans 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  with respect to delinquent  Non-Designated
Mortgage  Loans  so long as such  Holder  (A)  meets  the  requirements  for a
Subservicer   set   forth   in   Section 3.02(a),   (B)  will   service   such
Non-Designated  Mortgage  Loans in accordance  with this Agreement and (C) the
related  Servicer has the right to transfer such servicing  rights without the
payment of any compensation to a subservicer.

(g)   The Special  Servicer,  at its  option,  may (but is not  obligated  to)
purchase  from the Trust Fund,  (a) any Mortgage  Loan that is  delinquent  in
payment  90 or more days or (b) 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  subservicer.  Any  such  purchase  shall  be  made  by the
Special  Servicer  with its own funds at a price equal to the  Purchase  Price
for  such  Mortgage  Loan.  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 3.11(g).

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  will
immediately  notify the Custodian by delivering,  or causing to be delivered a
"Request for Release"  substantially  in the form of  Exhibit K.  Upon receipt
of such request,  the 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 the 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 Custodian within three
Business  Days of  delivery to the  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 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
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  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 the  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.

(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 is limited to, and payable
solely from, the interest portion of such Scheduled  Payments collected by the
related 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  not  required  to make  payments  in  respect of
Compensating  Interest  Payments  shall  be  retained  by SPS  and  WMMSC,  as
applicable.  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 3.18)  and shall not be
entitled to reimbursement  thereof except as specifically provided for in this
Agreement.

(c)   The Master Servicer shall be compensated by the Trust  Administrator  as
separately  agreed.  The Master 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)  and (y) the indemnity  amounts  payable by DLJMC or the Trust
to the  Trust  Administrator  pursuant  to  Section 10.05,  shall  not  exceed
$200,000 per year;  provided,  further,  that any amounts not payable by DLJMC
or the Trust to the Master  Servicer  due to the  preceding  proviso  shall be
payable by DLJMC (or if DLJMC fails to do so, by the Trust) in any  succeeding
year,  subject to the aggregate  $200,000 per annum limitation  imposed by the
preceding  proviso.  Such  indemnity  shall  survive the  termination  of this
Agreement or the resignation or removal of the Master Servicer hereunder.

SECTION 3.15.     Access to Certain Documentation.

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

such  officer and the nature and status  thereof and the action being taken by
such  Servicer  to cure such  default.  Upon each  receipt  of such  Officer's
Certificate  from any Servicer,  the Master Servicer shall promptly  deliver a
copy of such Officer's Certificate to the Depositor,  the Rating Agencies, the
Trustee and the Trust Administrator.

            Not later than the earlier of (a) March 15 of each  calendar  year

a default in the  fulfillment  of any such  obligation,  specifying  each such
default  known to such  officer  and the  nature and  status  thereof  and the

(who may also render other  services to the Master  Servicer or any  affiliate
thereof)  which is a member of the  American  Institute  of  Certified  Public
Accountants  to  furnish  a  statement  to the  Trust  Administrator  and  the

preceding  Business Day),  each Servicer (other than WMMSC and Wells Fargo) at
its  expense  shall  cause  a  nationally  or  regionally  recognized  firm of
independent  public  accountants  (who may also render other  services to such
Servicer,  the  Seller  or any  affiliate  thereof)  which is a member  of the
American  Institute of Certified Public  Accountants to furnish a statement to
the Trust Administrator,  the Master Servicer and the Depositor, to the effect
that with respect to each Servicer  (other than WMMSC and Wells  Fargo),  such
firm has examined  certain  documents and records relating to the servicing of
mortgage loans which such Servicer is servicing  which may include the related
Mortgage  Loans or  similar  mortgage  loans,  and that,  on the basis of such
examination,  conducted  substantially  in compliance  with the Uniform Single
Attestation  Program for Mortgage  Bankers or the Audit Guide for HUD Approved
Title II Approved  Mortgagees  and Loan  Correspondent  Programs,  nothing has
come to their  attention which would indicate that such servicing has not been
conducted in compliance  with  Accepted  Servicing  Practices,  except for (a)
such  exceptions  as such firm shall  believe to be  immaterial,  and (b) such
other  exceptions  as shall be set forth in such  statement.  In addition each
Servicer shall disclose to such firm all significant  deficiencies relating to

conducted  by such  firm  in  accordance  with  standards  established  by the
American  Institute of Certified Public  Accountants,  WMMSC has complied with
certain minimum  residential  mortgage loan servicing standards in its role as
master  servicer with respect to the servicing of  residential  mortgage loans
(including  the  WMMSC  Serviced  Mortgage  Loans)  during  the most  recently

matters relating to the  Certificates,  upon a statistical  sampling of series
of mortgage-backed  certificates which may include the Certificates and (b) as
to matters relating to the direct  servicing of residential  mortgage loans by
subservicers,  upon  comparable  reports  of  firms of  independent  certified
public  accountants  rendered  on  the  basis  of  examinations  conducted  in

the rules and  regulations  of the  Commission,  15 calendar  days before each
date on which the  Depositor's  annual  report on Form 10-K is  required to be

the  Commission  (or if  such  day  is not a  Business  Day,  the  immediately
preceding  Business  Day),  Wells  Fargo,  at  its  expense,   shall  cause  a
nationally or regionally  recognized  firm of independent  public  accountants
(who may  also  render  other  services  to Wells  Fargo,  the  Seller  or any
affiliate  thereof)  which is a member of the American  Institute of Certified
Public Accountants to furnish a statement to the Depositor,  and the Depositor
shall send copies of such  statement  to each of the Trust  Administrator  and
the  Master  Servicer,  to the  effect  that  such firm has  examined  certain
documents and records  relating to the servicing of mortgage loans which Wells
Fargo is servicing,  which may include the related  Mortgage  Loans or similar
mortgage  loans,  and  that,  on the  basis  of  such  examination,  conducted
substantially  in compliance with the Uniform Single  Attestation  Program for

the Master Servicer or such Servicer to the Trust Administrator.

SECTION 3.18.     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 3.18  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
acceptable  to 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 3.19.     Special Serviced Mortgage Loans.

            If  directed  by the  Special  Servicer  and solely at the Special
Servicer's  option,  a Servicer other than WMMSC (a  "Transferring  Servicer")
shall   transfer  the   servicing  of  any  Mortgage   Loan  serviced  by  the
Transferring  Servicer 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  Servicer  Letter
Agreement or other agreement not executed by the Special  Servicer.  Except as
provided in the preceding  sentence,  the Special  Servicer  shall service all
Special  Serviced  Mortgage Loans in accordance  with the servicing  standards
applicable  to  SPS  as if  SPS  were  the  Transferring  Servicer;  provided,
however,   that  the   obligations  of  SPS  set  forth  in   Section 8.01(h),
Section 8.01(i)  and Article XIII of this Agreement shall not be applicable to
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 shall, at the Special
Servicer's expense,  deliver to the Special Servicer all documents and records
relating to such  Mortgage  Loans and an  accounting  of amounts  collected or
held by it and  otherwise  use its best  efforts  to effect  the  orderly  and
efficient  transfer  of  the  servicing  to  the  Special  Servicer.   On  the
servicing   transfer   date,  the  Special   Servicer   shall   reimburse  the
Transferring  Servicer for all unreimbursed  Advances,  Servicing Advances and
Servicing  Fees, as  applicable,  relating to the Mortgage Loans for which the
servicing is being  transferred.  The Special Servicer shall be entitled to be
reimbursed  pursuant to Section 3.08  or otherwise  pursuant to this Agreement
for all such Advances,  Servicing  Advances and Servicing Fees, as applicable,
paid  by  the  Transferring   Servicer  pursuant  to  this  Section 3.19.   In
addition,  the  Special  Servicer  shall  notify the Master  Servicer  of such
transfer and the effective date of such transfer,  and amend the Mortgage Loan
Schedule to reflect that such  Mortgage  Loans are Special  Serviced  Mortgage
Loans.

SECTION 3.20.     Indemnification of Servicers and Master Servicer.

            Each Servicer,  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.

SECTION 3.21.     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 3.22.     Designated Mortgage Loans.

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

            The Master  Servicer shall terminate the rights and obligations of
any Designated  Servicer  under the related  Designated  Servicing  Agreement,
upon  the  failure  of  such  Designated   Servicer  to  perform  any  of  its
obligations under such Designated Servicing  Agreement,  which failure results
in an event of  default as  provided  in  Section 8.01  of the  National  City
Servicing Agreement,  with respect to National City, as provided in Section 14
of the  Countrywide  Servicing  Agreement,  with  respect to  Countrywide,  as
provided  in  Section 9.01  of the GMAC  Mortgage  Servicing  Agreement,  with
respect to GMAC  Mortgage,  and as  provided  in  Section 9.1  of the  E*TRADE
Servicing  Agreement,  with  respect  to  E*TRADE.  In the event a  Designated
Servicer  is  terminated  pursuant  to  the  preceding  sentence,  the  Master
Servicer  shall notify the  Depositor  and the Trust  Administrator  and shall
either (a) select and engage a  successor  servicer  of the  related  Mortgage
Loans or (b) act as  successor  servicer of the  related  Mortgage  Loans.  In
either  case,  the  Designated  Mortgage  Loans  related  to  such  Designated
Servicing  Agreement  shall be serviced by the  successor  to such  Designated
Servicer  pursuant to the  servicing  provisions of this  Agreement,  and such
Designated  Mortgage Loans shall be deemed as "Non-Designated  Mortgage Loans"
under this Agreement;  provided, however, it is understood and acknowledged by
the parties  hereto that there will be a period of  transition  (not to exceed
90 days) before the actual  servicing  functions can be fully  transferred  to
such successor  Designated  Servicer.  Such  enforcement,  including,  without
limitation,  the  legal  prosecution  of  claims,  termination  of  Designated
Servicing Agreements and the pursuit of other appropriate  remedies,  shall be
in such form and  carried out to such an extent and at such time as the Master
Servicer,  in its good faith  business  judgment,  would  require  were it the
owner of the related  Mortgage Loans.  The Master Servicer shall pay the costs
of such  enforcement  at its own expense,  provided  that the Master  Servicer
shall not be required to prosecute  or defend any legal  action  except to the
extent that the Master Servicer shall have received  reasonable  indemnity for
its costs and expenses in pursuing such action.

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

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

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

SECTION 3.23.     Assigned Prepayment Premiums.

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

   Stated  Principal  Balance of such Mortgage Loan as of the Due Date in such

   Mortgage Loan with respect to such month.  For purposes of calculating  the

   Certificates  with respect to Loan  Group 1,  Loan  Group 2,  Loan Group 3,
   Loan Group 4,  Loan Group 5 or Loan Group 6 such  reduction  shall be based

   of the related Subordinate Component Balance for that Distribution Date.

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

   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

                  Amount for Loan  Group 7B  in respect of such  distribution;
                  and

(2)   amounts  distributed  to the  Class 7-A-2  Certificates  will reduce the

Servicer with respect to the related Prepayment Period.

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,  Loan Group 4,  Loan Group 5 and Loan Group 6 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-7
      Certificates),  until the  respective  Class  Principal  Balance of each
      such Class is 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; and

(ii)  Excess  Losses  in  respect  of  principal  for  Mortgage  Loans in Loan
      Group 1,  Loan  Group 2,  Loan Group 3,  Loan Group 4,  Loan Group 5 and
      Loan  Group 6 will be allocated  among all  Group 1,  Group 2,  Group 3,
      Group 4,  Group 5,  Group 6  and the  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,  Group 5,  Group 6  and  Class C-B
Certificates  exceeds the aggregate Stated  Principal  Balance of the Mortgage
Loans in Loan Group 1,  Loan Group 2, Loan Group 3, Loan Group 4, Loan Group 5
and Loan Group 6  (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(A)(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(A)(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 of the Applied Loss Amount with respect to the Group 7 Certificates,  if
any, for such  Distribution  Date. The Applied Loss Amount with respect to the
Group 7  Certificates for any  Distribution  Date shall be applied by reducing
the Class Principal Balance of each Class of Group 7 Subordinate  Certificates
beginning   with  the  Class  of   Group 7   Subordinate   Certificates   then
outstanding,  other than the Class 7-X Certificates,  with the lowest relative
payment  priority,  in each case until the respective Class Principal  Balance
thereof  is reduced to zero.  Any  Applied  Loss  Amount  with  respect to the
Group 7 Certificates allocated to a Class of Group 7 Subordinate  Certificates
shall be allocated  among the Group 7  Subordinate  Certificates of such Class
in proportion to their respective Percentage Interests.

(f)   All Realized Losses on the Group 1,  Group 2,  Group 3, Group 4, Group 5
and Group 6  Mortgage  Loans shall be allocated on each  Distribution  Date to
the REMIC I Regular  Interests and REMIC III  Regular Interests as provided in
the definitions of REMIC I Realized Losses and REMIC III Realized Losses.

(g)   All Realized Losses on the Group 7  Mortgage Loans shall be allocated on
each  Distribution  Date  to the  REMIC II  Regular  Interests  and  REMIC III
Regular  Interests as provided in the definitions of REMIC II  Realized Losses
and REMIC III Realized Losses.

(h)   Realized Losses on the Group 7  Mortgage Loans that are not Applied Loss
Amounts  shall be deemed  allocated to the  Class 7-X  Certificates.  Realized
Losses  allocated to the Class 7-X  Certificates  shall, be allocated  between
the  REMIC IV  Regular   Interests  7-X-IO  and  7-X-PO  as  provided  in  the
definition of Realized Losses.

(i)   Realized  Losses shall be  allocated  among the REMIC I, REMIC II, REMIC
III and REMIC IV Regular  Interests as specified in the definition of Realized
Losses and, as to REMIC I, REMIC II and REMIC III  Regular  Interests,  in the
definitions  of REMIC I Realized  Losses,  REMIC II Realized  Losses and REMIC
III Realized Losses, respectively.

SECTION 4.03.     Recoveries.

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

(i)   with  respect to  Recoveries  on  Group 1,  Group 2,  Group 3,  Group 4,
      Group 5 and Group 6 Mortgage Loans,

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

(B)   second,   the  Class  Principal  Balance  of  each  Class  of  Class C-B
            Certificates  will be increased in order of  seniority,  up to the
            amount of Net Recovery Realized Losses for each such Class; or

(ii)  with  respect  to  Recoveries  on  Group 7  Mortgage  Loans,  the  Class
      Principal  Balance  of  each  Class  of  Class  M  Certificates  will be
      increased in order of  seniority,  up to the Deferred  Amount such Class
      is  entitled  to  receive  pursuant  to   Section 4.01(II)(d)   on  such
      Distribution  Date  prior to  giving  effect  to  payments  pursuant  to
      Section 4.01(II)(d) on such Distribution Date.

(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.     Reserved.

SECTION 4.05.     Monthly Statements to Certificateholders.

(a)   Not later than each  Distribution  Date, the Trust  Administrator  shall

Servicer,  each Servicer, the Trustee, the Depositor,  and each Rating Agency,
a statement  setting forth with respect to the related  distribution:  (A) the
items listed in  Exhibit S,  other than items  (vi)(a),  (vi)(b),  (vi)(c) and

            On each Distribution Date, the Trust  Administrator  shall provide

connection  with providing the information  specified in this  Section 4.05 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

to in  Section 4.05(a)  via  the  Trust  Administrator's  website.  The  Trust
Administrator's website can be accessed at  http://www.ctslink.com  or at such

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 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

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.

SECTION 4.06.     Servicer to Cooperate.

            Each  Servicer,  other  than  WMMSC,  shall  provide to the Master
Servicer the  information  set forth in Exhibit H,  and any other  information
the  Master  Servicer  requires,  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,  twelve noon 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.

            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  Exhibit H  in such form as the Trust  Administrator
shall  reasonably  request no later than  twelve  noon on the Data  Remittance
Date 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 4.07.     Cross-Collateralization; Adjustments to Available Funds.

(a)   On  each  Distribution  Date  prior  to the  Class  C-B  Credit  Support
Depletion  Date,  but after the date on which the  aggregate  Class  Principal
Balance  of  the  Group 1,  Group 2,  Group 3,  Group 4,  Group 5  or  Group 6
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,  Group 4, Group 5 and Group 6 Certificates is
greater than the aggregate Stated  Principal  Balance of the Mortgage Loans in
the  related  Loan  Group  (each  such  Loan  Group,  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 (without  giving effect to any reduction for any Excess
      Interest  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
      Stated  Principal  Balance of the  Mortgage  Loans in the  related  Loan
      Group(s).  Payments  shall be made to the  Senior  Certificates  in each
      Group in the same  priority as such  Certificates  would  receive  other
      distributions of principal pursuant to Section 4.01(I)(A).

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

                ADVANCES BY THE MASTER SERVICER AND SERVICERS

SECTION 5.01.     Advances by the Master Servicer and Servicers.

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

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

            With respect to any  Non-Designated  Mortgage  Loan, if the amount
of  Advances  received  from a Servicer,  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 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.

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

                                  ARTICLE VI

                               THE CERTIFICATES

SECTION 6.01.     The Certificates.

            The Certificates  shall be in substantially the forms set forth in
Exhibits A, B, C, D-1,  D-2, E, F-1, F-2 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 11.02  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   therefore,   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

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

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

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

SECTION 6.02.     Registration of Transfer and Exchange of Certificates.

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

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

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

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

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

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

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

(i)   Each  Person  who  has or  who  acquires  any  ownership  interest  in a
      Class AR or Class AR-L  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  Class AR  or  Class AR-L   Certificate  are
      expressly subject to the following provisions:

(A)   Each Person  holding or acquiring any  ownership  interest in a Class AR
         or  Class AR-L   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
         Class AR  or  Class AR-L  Certificate  to a U.S.  Person,  the  Trust
         Administrator  shall  require  delivery to it, and shall not register
         the  transfer  of a  Class AR  or  Class AR-L  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 Class AR or Class AR-L  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  Class AR  or
         Class AR-L  Certificate,  it will  endeavor  to remain  other  than a
         Disqualified  Organization,  and that it has reviewed the  provisions
         of this  Section 6.02(g)  and  agrees to be bound by them,  and (2) a
         certificate,  attached  hereto as Exhibit O,  from the Holder wishing
         to  transfer  a  Class AR  or  Class AR-L  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 Class AR or Class AR-L  Certificate  to such
         proposed transferee shall be effected.

(D)   Each Person  holding or acquiring any  ownership  interest in a Class AR
         or  Class AR-L  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 Class AR or
      Class AR-L  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
         Class AR or Class AR-L  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  Class AR  or  Class AR-L  Certificate.  If any non
         U.S. Person  shall  become  a  Holder  of a  Class AR  or  Class AR-L
         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
         Class AR or  Class AR-L  Certificate.  If a transfer of a Class AR or
         Class AR-L  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  Class AR  or  Class AR-L
         Certificate.  The Trust  Administrator shall be under no liability to
         any  Person  for  any  registration  of  transfer  of a  Class AR  or
         Class AR-L  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 Class AR or  Class AR-L  Certificate
         shall  become a Holder of a Class AR  or  Class AR-L  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  Class AR or  Class AR-L  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  Class AR or  Class AR-L  Certificate,  to sell
         such Class AR or Class AR-L  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 Class AR
         or Class AR-L  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  Class AR  or
         Class AR-L   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 Class AR or  Class AR-L  Certificate  to any
      Person who is not other than a Disqualified Organization,  including the
      information  regarding "excess inclusions" of such Residual  Certificate
      required  to be  provided to the  Internal  Revenue  Service and certain
      Persons as described in Treasury Regulation  Section 1.860D 1(b)(5), and
      (B) as a  result  of  any  regulated  investment  company,  real  estate
      investment  trust,  common  trust fund,  partnership,  trust,  estate or
      organizations  described in Section 1381 of the Code having as among its
      record  holders  at  any  time  any  Person  who  is  not  other  than a
      Disqualified  Organization.  Reasonable  compensation for providing such
      information  may be  required  by the  Master  Servicer  or the  related
      Servicer from such Person.

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

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

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

(vi)  The  following  legend  shall  appear  on each  Class AR  or  Class AR-L
      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 [CLASS AR][CLASS AR-L]  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  THE   [CLASS AR][CLASS AR-L]   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 Class AR or Class AR-L  Certificate if it has actual knowledge
that the proposed  transferee does not meet the  qualifications of a permitted
Holder  of  a  Class AR  or  Class AR-L  Certificate  as  set  forth  in  this
Section 6.02.

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

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

SECTION 6.04.     Persons Deemed Owners.

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

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

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

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

SECTION 6.06.     Maintenance of Office or Agency.

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

SECTION 6.07.     Book Entry Certificates.

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

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

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

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

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

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

SECTION 6.08.     Notices to Clearing Agency.

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

SECTION 6.09.     Definitive Certificates.

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

            Subject to the immediately  succeeding  paragraph,  the Depositor,
the Seller, the Master Servicer,  the Back-Up Servicer,  each Servicer and the
Special  Servicer  will each do or cause to be done all  things  necessary  to
preserve  and  keep in  full  force  and  effect  its  existence,  rights  and

qualification to do business as a foreign  corporation in each jurisdiction in
which such  qualification is or shall be necessary to protect the validity and
enforceability of this Agreement,  or any of the Mortgage Loans and to perform
its respective duties under this Agreement.

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

the  Seller,  the  Back-Up  Servicer  or such  Servicer,  as the  case may be,
hereunder,  without the execution or filing of any paper or any further act on
the  part  of any of the  parties  hereto,  anything  herein  to the  contrary
notwithstanding;  provided,  however,  that (i)  except in  connection  with a
transfer of servicing  pursuant to  Section 7.04(c)  hereof,  the successor or
surviving  Person to the  Master  Servicer,  the  Back-Up  Servicer,  any such
Servicer  (other than WMMSC) or the Special  Servicer  shall be  qualified  to

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;  and provided further, (a) except in connection with a transfer of
servicing  pursuant  to  Section 7.04(c)   hereof,   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,  the  Back-Up  Servicer or such  Servicer,  with like
effect  as if  originally  named as a party to this  Agreement;  and  provided
further,   except  in  respect  of  any  transfer  of  servicing  pursuant  to
Section 7.04(c)  hereof, that each of the Rating Agencies acknowledge that its
rating of the  Certificates  in effect  immediately  prior to such  assignment
will  not  be  qualified  or  reduced  as a  result  of  such  assignment  and
delegation.  In the case of any such  assignment  and  delegation,  the Master
Servicer,  the Back-Up  Servicer or such  Servicer  shall be released from its
obligations under this Agreement  (except as provided above),  except that the
Master Servicer,  Back-Up Servicer or the related Servicer shall remain liable
for all  liabilities and  obligations  incurred by it as the Master  Servicer,
Back-Up  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 Back-Up Servicer, the
                              Servicers, the Special Servicer and Others.

            None of the Depositor,  the Master Servicer, the Back-Up Servicer,
any Servicer,  the Seller,  the Special  Servicer,  nor any of the  directors,
officers,  employees  or agents of the  Depositor,  the Master  Servicer,  the
Back-Up  Servicer,  any Servicer,  the Seller or the Special Servicer shall be
under any  liability  to the  Certificateholders  for any action  taken or for
refraining  from the  taking of any  action  in good  faith  pursuant  to this
Agreement, or for errors in judgment;  provided,  however, that this provision
shall not protect the Depositor,  the Master Servicer,  the Back-Up  Servicer,
any  Servicer,  the  Seller or the  Special  Servicer  against  any  breach of
representations or warranties made by it herein or protect the Depositor,  the
Master  Servicer,  the  Back-Up  Servicer,  any  Servicer,  the  Seller or the
Special  Servicer or any such  director,  officer,  employee or agent from any
liability which would otherwise be imposed by reasons of willful  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,  the  Back-Up  Servicer,  any  Servicer,  the Seller and the
Special  Servicer  and  any  director,  officer,  employee  or  agent  of  the
Depositor,  the Master  Servicer,  the Back-Up  Servicer,  any  Servicer,  the
Seller or the Special  Servicer  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,  the Back-Up
Servicer,  any Servicer, the Seller and the Special Servicer and any director,
officer,  employee or agent of the Depositor, the Master Servicer, the Back-Up
Servicer,   any  Servicer,  the  Seller  or  the  Special  Servicer  shall  be
indemnified  by the Trust Fund and held harmless  against any loss,  liability
or expense  incurred  in  connection  with any legal  action  relating to this
Agreement  or 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,  the  Back-Up  Servicer,  any  Servicer,  the Seller or the  Special
Servicer shall be under any  obligation to appear in,  prosecute or defend any
legal action that is not incidental to their  respective  duties hereunder and
which in its opinion may  involve it in any  expense or  liability;  provided,
however, that the Depositor,  the Master Servicer,  the Back-Up Servicer,  any
Servicer,  the Seller or the Special Servicer may in its discretion  undertake
any such action that it may deem  necessary  or  desirable  in respect of this
Agreement  and the rights and duties of the parties  hereto and  interests  of
the Trustee,  the Trust  Administrator and the  Certificateholders  hereunder;
provided,  however,  that in the event the related Servicer (other than WMMSC)
agrees,  at the request of the  Seller,  to act on behalf of the Seller in any
dispute  or  litigation  that  is not  incidental  to such  Servicer's  duties
hereunder and that relates to the  origination  of a Mortgage Loan, the Seller
shall pay all  expenses  associated  with the  management  and defense of such
claim.  Anything in this  Agreement  to the  contrary  notwithstanding,  in no
event shall the Master  Servicer,  the Back-Up  Servicer,  any Servicer or the
Special  Servicer be liable for  special,  indirect or  consequential  loss or
damage of any kind  whatsoever  (including  but not limited to lost  profits),
even if the Master  Servicer,  the Back-Up  Servicer,  the related Servicer or
the  Special  Servicer  has been  advised  of the  likelihood  of such loss or
damage and regardless of the form of action.

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

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

(b)   Notwithstanding the foregoing,  at DLJMC's request, so long as it is the
owner of the  related  servicing  rights,  the  Master  Servicer  or SPS shall
resign,  upon the selection and appointment of a successor  master servicer or
servicer,  as applicable;  provided that DLJMC delivers to the Trustee and the
Trust   Administrator  the  letter  required  in  Section   7.04(a)(i)  above.
Notwithstanding  the  foregoing,  in the event  that the  Master  Servicer  is
appointed  as the  successor  servicer  to SPS,  the  requirements  of Section
7.04(a)(i)  shall  be  waived.  In  connection  with  the  foregoing,   unless
otherwise  directed by DLJMC in writing on or prior to February 1, 2005, DLJMC
hereby  directs SPS to resign as Servicer  hereunder  and  appoints the Master
Servicer to service the SPS Serviced Mortgage Loans,  effective as of March 1,
2005.  In  connection  with its  resignation,  SPS hereby agrees to deliver to
the Master  Servicer on the date of its  resignation a schedule  setting forth
all of the SPS  Mortgage  Loans as of such date.  The Master  Servicer  agrees
that,  as of March 1, 2005, it will service the SPS Serviced  Mortgage  Loans,
and that such loans shall constitute  Wells Fargo Serviced  Mortgage Loans, in
accordance  with the terms of this Agreement.  If the Master Servicer  resigns
pursuant  to this  Section  7.04(b),  DLJMC  shall pay the Master  Servicer an
amount equal to the product of (a) the Stated Principal  Balance of all of the
Mortgage  Loans  then  outstanding  and (b)  0.02%.  In  connection  with  any
resignation  of SPS pursuant to this Section  7.04(b),  DLJ Mortgage  Capital,
Inc.  may  designate  one or more  Servicers  (which  may be  SPS's  successor
servicer) to act as the Terminating Entity under this Agreement.

(c)   Notwithstanding  anything to the contrary in this  Agreement,  servicing
with respect to all or a portion of the Eligible  Servicing Transfer Loans may
be  transferred  to WMMSC  under this  Agreement  upon  written  notice  being
delivered to the Trustee,  the Master Servicer,  the Depositor,  DLJMC and the
Trust  Administrator.  Any transfer of servicing with respect to such Eligible
Servicing   Transfer   Loans  shall  not  require  the  letter  set  forth  in
Section 7.04(a)(i)  above or any consent  from the  Certificateholders  or any
other party  hereto.  Upon the transfer of servicing to WMMSC,  such  Mortgage
Loans shall be serviced in  accordance  with the  procedures  WMMSC employs in
servicing Mortgage Loans serviced by it under this Agreement.

(d)   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.

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


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

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

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

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

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

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

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

and a Rating on the  Certificates to "below average" or below,  except for any
downgrade  by Fitch to "below  average"  or below  within  nine  months of the

attributable  solely to SPS or the servicing of the SPS Mortgage  Loans by SPS

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

may,  if such  Event  of  Default  is due to the  actions  or  inactions  of a

such Servicer under this  Agreement  (other than rights to  reimbursement  for

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

rights or duties of any other  Servicer or  constitute  an Event of Default as
to any other Servicer.

            If an Event of Default  set forth in clause  (h)(ii)  above  shall

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

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

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

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

            A  Replaced  Servicer  that  has  been  terminated  shall,  at the
request of the Trustee,  the Trust  Administrator,  the Master Servicer or the
Back-Up Servicer, as applicable,  but at the expense of such Replaced Servicer
deliver to the  assuming  party all  documents  and  records  relating  to the
applicable  Mortgage Loans and an accounting of amounts  collected and held by
it and otherwise  use  commercially  reasonable  efforts to effect the orderly
and  efficient  transfer and  assignment  of such  servicing,  but only to the
extent of the Mortgage  Loans  serviced  thereunder,  to the  assuming  party.
Notwithstanding  anything to the contrary contained herein, the termination of
a Servicer under this Agreement shall not extend to any  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,  the Back-Up Servicer and each Servicer shall
cooperate  with the  Trustee  and the Trust  Administrator  and any  successor
servicer   in   effecting   the   termination   of   a   Replaced   Servicer's
responsibilities  and rights  hereunder,  including  without  limitation,  the
transfer to such successor for  administration by it of all cash amounts which
shall at the time be credited by such  Servicer to the  applicable  Collection
Account or thereafter received with respect to the Mortgage Loans.

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

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

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

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

SECTION 8.03.     Notification to Certificateholders.

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

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

SECTION 8.04.     Waiver of Events of Default.

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

                                  ARTICLE IX

                            CONCERNING THE TRUSTEE

SECTION 9.01.     Duties of Trustee.

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

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

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

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

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

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

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

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

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

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

SECTION 9.02.     Certain Matters Affecting the Trustee.

(a)   Except as otherwise provided in Section 9.01:

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

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

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

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

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

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

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

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

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

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

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

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

SECTION 9.04.     Trustee May Own Certificates.

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

SECTION 9.05.     Trustee's Fees and Expenses.

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

SECTION 9.06.     Eligibility Requirements for Trustee.

            The  Trustee  hereunder  shall at all  times be a  corporation  or
association  organized and doing  business  under the laws of any state or the
United  States of America,  authorized  under such laws to exercise  corporate
trust powers,  having ratings on its long term debt obligations at the time of
such  appointment  in at least  the  third  highest  rating  category  by both
Moody's  and S&P or such  lower  ratings  as will not cause  Moody's or S&P to
lower their then-current  ratings of the Class A  Certificates (other than the
Class 7-X and Residual  Certificates),  having a combined  capital and surplus
of at least  $50,000,000  and subject to supervision or examination by federal
or state authority.  If such corporation or association  publishes  reports of
condition at least  annually,  pursuant to law or to the  requirements  of the
aforesaid  supervising or examining  authority,  then for the purposes of this
Section 9.06   the  combined  capital  and  surplus  of  such  corporation  or
association  shall be deemed to be its  combined  capital  and  surplus as set
forth in its most recent  report of  condition  so  published.  In case at any
time the Trustee shall cease to be eligible in accordance  with the provisions
of this  Section 9.06,  the Trustee shall resign immediately in the manner and
with the effect specified in Section 9.07 hereof.

SECTION 9.07.     Resignation and Removal of Trustee.

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

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

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

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

SECTION 9.08.     Successor Trustee.

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

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

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

SECTION 9.09.     Merger or Consolidation of Trustee.

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

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

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

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

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

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

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

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

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

SECTION 9.11.     Office of the Trustee.

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

                                  ARTICLE X

                      CONCERNING THE TRUST ADMINISTRATOR

SECTION 10.01.    Duties of Trust Administrator.

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

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

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

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

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

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

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

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

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

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

SECTION 10.02.    Certain Matters Affecting the Trust Administrator.

(a)   Except as otherwise provided in Section 10.01:

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

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

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

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

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

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

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

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

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

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

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

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

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

SECTION 10.04.    Trust Administrator May Own Certificates.

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

SECTION 10.05.    Trust Administrator's Fees and Expenses.

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

SECTION 10.06.    Eligibility Requirements for Trust Administrator.

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

SECTION 10.07.    Resignation and Removal of Trust Administrator.

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

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

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

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

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

SECTION 10.08.    Successor Trust Administrator.

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

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

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

SECTION 10.09.    Merger or Consolidation of Trust Administrator.

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

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

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

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

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

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

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

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

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

SECTION 10.11.    Office of the Trust Administrator.

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

SECTION 10.12.    Tax Return.

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

SECTION 10.13.    Commission Reporting.

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

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

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

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

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

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

(f)   If  the  Commission   issues  additional   interpretative   guidance  or
promulgates   additional  rules  or  regulations,   or  if  other  changes  in
applicable law occur,  that would require the reporting  arrangements,  or the
allocation  of  responsibilities  with  respect  thereto,  described  in  this

and binding, absent a manifest error of the Trust Administrator.

(iii), collectively,  the "Par Value") and (b) the Fair Market Value of all of
the property of the Trust.

            The "Fair  Market  Value" shall be the fair market value of all of
the property of the Trust, 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 all the
property of the Trust,  the Terminating  Entity,  or an agent appointed by the
Terminating  Entity,  shall  solicit bids for all of the 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.

SECTION 11.02.    Procedure Upon Optional Termination.

(a)   In case of any  Optional  Termination  pursuant  to  Section 11.01,  the
Terminating  Entity shall, at least twenty days prior to the date notice is to
be mailed to the affected  Certificateholders notify the Trustee and the Trust
Administrator  of  such  Optional  Termination  Date  and  of  the  applicable
purchase   price  of  the   Mortgage   Loans  to  be   purchased.   The  Trust
Administrator  shall give notice to the Rating  Agencies and the  Servicers of
election to purchase the Mortgage Loans pursuant to  Section 11.01  hereof and
of the Optional Termination Date.

(b)   Any purchase of the Mortgage  Loans by the  Terminating  Entity shall be
made on an Optional  Termination  Date by deposit of the  applicable  purchase
price into the Certificate  Account,  as applicable,  before the  Distribution
Date  on  which  such  purchase  is  effected.   Upon  receipt  by  the  Trust
Administrator   of  an  Officer's   Certificate  of  the  Terminating   Entity
certifying  as to the  deposit of such  purchase  price  into the  Certificate
Account, the 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)   Notice  of the  Distribution  Date  on  which  the  Trust  Administrator
anticipates that the final  distribution  shall be made (whether upon Optional
Termination 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  or  date  of  final
distribution,   as  the  case  may  be.  Such  notice  shall  specify  (i) the
Distribution Date upon which final  distribution on the affected  Certificates
will be made upon  presentation  and  surrender  of such  Certificates  at the
office  or  agency  therein   designated,   (ii)  the  amount  of  such  final
distribution  and (iii)  that the Record  Date  otherwise  applicable  to such
Distribution Date is not applicable,  such  distribution  being made only upon
presentation  and  surrender  of such  Certificates  at the  office  or agency
maintained  for such purposes (the address of which shall be set forth in such
notice).

(d)   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.

(e)   Notwithstanding  anything to the contrary  herein,  the occurrence of an
Optional  Termination  shall be  subject  to,  and  shall in no way  adversely
affect  (i) the  right of WMMSC  to  continue  servicing  and  collecting  its
Servicing Fee for any WMMSC  Serviced  Mortgage Loan that remains  outstanding
at the  time of such  Optional  Termination,  (ii) the  right of U.S.  Bank to
continue  servicing  and  collecting  its  Servicing  Fee  for any  U.S.  Bank
Serviced  Mortgage Loan that remains  outstanding at the time of such Optional
Termination  and (ii)  the  right of Wells  Fargo to  continue  servicing  and
collecting its Servicing Fee for any Wells Fargo  Serviced  Mortgage Loan that
remains outstanding at the time of such Optional Termination.

SECTION 11.03.    Additional Termination Requirements.

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

(i)   within  90 days  prior to the final  Distribution  Date set forth in the
      notice given by Terminating  Entity under  Section 11.02,  the Holder of
      the Class AR or Class AR-L  Certificates  shall adopt a plan of complete
      liquidation of REMIC I or REMIC II, as applicable; and

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

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

(i)   concurrently  with the adoption of the plan of complete  liquidation  of
      the  Second  Subsidiary  REMIC,  as set forth in  paragraph  (a) of this
      Section,  the Holder of the  Class AR  or  Class AR-L  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 Second  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 Class AR or Class AR-L  Certificate,  the Holder
thereof  hereby  agrees to adopt such a plan of  complete  liquidation  and to
take such other action in connection  therewith as may be reasonably  required
to  liquidate  and  otherwise  terminate  any REMIC  created  pursuant to this
Agreement.

      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

      adversely   affect  in  any  material   respect  the  interests  of  any
      Certificateholder  or  cause  an  Adverse  REMIC  Event.  Any  Amendment
      pursuant to Section 12.01(a)(v)  shall not be deemed to adversely affect
      in any  material  respect the  interests of any  Certificateholder  if a
      letter is obtained from each Rating Agency  stating that such  amendment
      would not result in the  downgrading  or  withdrawal  of the  respective
      ratings then assigned to the Certificates.

(b)   Except as provided in  Section 12.01(c),  this  Agreement may be amended
from time to time by the Depositor,  the Master Servicer,  the Servicers,  the

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  or (v)  modify  the
provisions of this Section 12.01.

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

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

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

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

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

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

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

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

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

SECTION 12.02.    Recordation of Agreement; Counterparts.

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

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

SECTION 12.03.    Governing Law.

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

SECTION 12.04.    Intention of Parties.

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

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

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 12.06.    Severability of Provisions.

            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,  agreements,  provisions  or  terms  of  this
Agreement  and shall in no way affect the  validity or  enforceability  of the
other  provisions of this  Agreement or of the  Certificates  or the rights of
the Holders thereof.

SECTION 12.07.    Limitation on Rights of Certificateholders.

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

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

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

SECTION 12.08.    Certificates Nonassessable and Fully Paid.

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

SECTION 12.09.    Protection of Assets.

            Except for transactions and activities  entered into in connection
with the  securitization  that 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 Interest or
otherwise,  solicit  the  borrower  or  obligor  under  any  Mortgage  Loan to
refinance  the  Mortgage  Loan,  in  whole  or in  part.  Notwithstanding  the
foregoing,  it is  understood  and agreed that  promotions  undertaken  by the
Depositor,  the Seller, the Master Servicer,  any Servicer (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   shall  not  constitute
solicitation  under  this  Section 12.10,  provided,  that no  segment  of the
general public shall consist  primarily of the borrowers or obligors under the
Mortgage Loans.  None of the Depositor,  the Seller,  the Master  Servicer,  a
Servicer  (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

                         SPS AND THE MASTER SERVICER

      provide the Master  Servicer  with a report  listing  each SPS  Mortgage
      Loan  that has  liquidated  or been  satisfied  in full  indicating  the
      information,  or information  substantially  similar to the information,
      contained in Exhibit P  together with all supporting  documentation  for
      the prior calendar month.

(iii) Mortgage Guaranty Insurance Policy Claims - Where applicable,  SPS shall
      provide the Master  Servicer  with copies of all claims  filed under any
      Mortgage Guaranty Insurance Policy and the actual amount paid,  together
      with the explanation of benefits  ("EOB") for each claim filed under any
      Mortgage  Guaranty  Insurance  Policy in respect of a SPS Mortgage Loan.
      SPS shall remit the related Insurance  Proceeds within five (5) Business
      Days after their  receipt,  submit to the Master  Servicer a foreclosure
      settlement  statement  substantially  in the  form  attached  hereto  as
      Exhibit Q  and agrees not to deduct any  related  expenses  prior to the
      Master  Servicer's  approval  of  the  related  foreclosure   settlement
      statement.

(iv)  Loss and  Delinquency  Test - SPS shall provide the Master Servicer with
      all information  required for calculating the Loss and Delinquency Test,
      including but not limited to:

(A)   Loan level and aggregate  Stated  Principal  Balance of all SPS Mortgage
            Loans 61-90 days delinquent  including any loan(s) delinquent on a
            bankruptcy plan;

(B)   Loan level and aggregate  Stated  Principal  Balance of all SPS Mortgage
            Loans 91 days and greater (that are not in foreclosure)  including
            any loan(s) delinquent on a bankruptcy plan;

(C)   Loan level and aggregate  Stated  Principal  Balance of all SPS Mortgage
            Loans that are active foreclosures;

(D)   Loan level and aggregate  Stated  Principal  Balance of all SPS Mortgage
            Loans that are active REOs; and

(E)   Due dates  for all SPS  Mortgage  Loans  reported  under the  categories
            listed above in (A) through (D).

(b)   SPS shall make its servicing  personnel available during normal business
hours to  respond,  either  orally or in  writing by  facsimile  transmission,
express mail, or electronic mail, to reasonable  inquiries  transmitted by the
Master  Servicer with respect to any SPS Mortgage Loan provided that SPS shall
only be  required  to  provide  information  that is  readily  accessible  and
available to its servicing personnel.

SECTION 13.02.    Master Servicer's Oversight With Respect to the SPS
Mortgage Loans.

(a)   The Master  Servicer  shall be  permitted  to provide  SPS with  advice,
reports  and  recommendations   regarding  SPS'  collection  efforts  and  the
management  of  specific  SPS  Mortgage  Loans,  which  advice  may be made in
writing,  in the form of  electronic  mail or  verbally.  Such advice shall be
based   on  an   evaluation   of  the   information   provided   pursuant   to
Section 13.01(a).   The  advice  may  include   comparable   analysis  of  the
performance of the SPS Mortgage Loans with similar  mortgage loans serviced by
other  mortgage  loan  servicers.  Such  advice  may  also  take  the  form of
benchmark   comparisons   that  identify  and  interpret  SPS'  strengths  and
weaknesses relative to similar, unidentified servicers in the industry.

(b)   Each party to the  Agreement  acknowledges  that the  Master  Servicer's
advice is made in the form of  recommendations,  and that the Master  Servicer
does not have the right to direct  SPS in  performing  its  duties  under this
Agreement.  SPS may,  after review and analysis of any  recommendation  of the
Master  Servicer  accept  or reject  such  advice,  in SPS'  sole  discretion,
subject to the duties and obligations of SPS set forth in this Agreement.

SECTION 13.03.    Termination.

            The rights and  obligations of the Master  Servicer under Sections
13.01 and 13.02 of this Agreement  shall terminate upon the earlier of (i) the
appointment of a successor  Servicer to SPS hereunder for all the SPS Mortgage
Loans or (ii)  the  receipt  by SPS of a rating  of  "above  average"  (or its
equivalent) or better as a servicer of subprime  mortgage loans by each Rating
Agency  that  maintains  a  servicer   rating  system  and  a  Rating  on  the
Certificates.

SECTION 13.04.    Liability and Indemnification.

            Neither the Master Servicer,  nor any of its respective directors,
officers,  employees,  or agents shall be under any  liability  for any action
taken or for  refraining  from the taking of any action in good faith pursuant
to  Sections  13.01 and 13.02 of this  Agreement  or for  errors in  judgment;
provided,  however,  that this provision shall not protect the Master Servicer
or any such other  Person  against  any  liability  which would  otherwise  be
imposed by reason of willful  misfeasance,  bad faith or gross  negligence  in
the  performance of duties or by reason of disregard of obligations and duties
hereunder. The Master Servicer and any director,  officer,  employee, or agent
thereof  shall be entitled  to rely in good faith on any  document of any kind
prima facie  properly  executed  and  submitted by any Person  respecting  any
matters arising hereunder.

SECTION 13.05.    Confidentiality.

            The  Master   Servicer   agrees  that  all   material,   nonpublic
information  supplied  to it by or on  behalf  of  SPS  relating  to  the  SPS
Serviced  Mortgage  Loans or details of SPS'  operations  or SPS'  proprietary
systems shall be treated  confidentially  except as otherwise  provided by the
terms of this  Agreement or as required by law; it being  understood  that the
provision of any such  information  by the Master  Servicer to any party shall
not cause  such  information  to be  considered  public for  purposes  of this
Section 13.05.  The Master  Servicer  shall  indemnify  SPS  against any loss,
liability,  claims, charges,  damages, fines, penalties,  judgments,  actions,
suits,  costs and such other expenses  incurred by SPS as a result of a breach
by the Master Servicer of its obligations under this Section 13.05.


            IN  WITNESS  WHEREOF,  the  Depositor,   the  Seller,  the  Master
Servicer,  the Servicers,  the Back-Up  Servicer,  the Special  Servicer,  the
Trustee  and the Trust  Administrator  have  caused  their  names to be signed
hereto by their  respective  officers  thereunto duly authorized all as of the
