ITEM 5.     OTHER EVENTS
            ------------

            On  October  12,  1999,   Asset  Backed  Funding   Corporation  (the
"Corporation"),  sold United  PanAm  Mortgage  Loan Asset  Backed  Certificates,
Series 1999-2, Class A-1 and Class A-2 (the "Offered  Certificates"),  having an
aggregate   original   principal   balance  of   $233,144,000.00.   The  Offered
Certificates were issued pursuant to the Pooling and Servicing Agreement,  dated
as of October 1, 1999 (the  "Agreement"),  among the  Corporation,  Pan American
Bank,  FSB, as seller and master  servicer  (the "Master  Servicer"),  Fairbanks
Capital  Corp.,  as special  servicer,  and Bankers Trust Company of California,
N.A., as trustee (the "Trustee"), a copy of which is filed as an exhibit hereto.
United PanAm Mortgage Loan Asset Backed Certificates, Series 1999-2, Class X and
Class R (the "Private Certificates" and, together with the Offered Certificates,
the  "Certificates"),  were also issued  pursuant to the  Agreement but were not
publicly offered.

            Credit  support  for  the  Offered  Certificates  is  provided  by a
financial guaranty insurance policy (the "Certificate  Insurance Policy") issued
by Financial  Security  Assurance  Inc.  ("FSA") in favor of the Trustee for the
benefit of the Certificateholders of the Offered Certificates.

            As of  the  date  of  initial  issuance,  the  Offered  Certificates
evidenced  beneficial  ownership interests in a trust (the "Trust"),  consisting
primarily of (i) two groups of mortgage  loans,  each divided into two subgroups
consisting  of  fixed-rate  and  adjustable-rate   mortgage  loans,  secured  by
mortgages creating first liens on one- to four-family properties,  (ii) funds on
deposit in the pre-funding accounts and capitalized interest accounts, (iii) the
Certificate  Insurance Policy, (iv) a primary mortgage guaranty insurance policy
issued  by  Mortgage  Guaranty  Insurance  Corporation  and  (v)  certain  other
property.  The remaining  undivided  interests in the Trust are evidenced by the
Private Certificates.

            Interest on the Offered  Certificates  will be  distributed  on each
Distribution  Date (as  defined  in the  Agreement).  Monthly  distributions  in
reduction of the principal balance of the Offered Certificates will be allocated
to the Offered  Certificates  in accordance with the priorities set forth in the
Agreement.

            An election will be made to treat certain assets of the Trust as one
or more real estate mortgage investment conduits for federal income tax purposes
(each, a "REMIC").  The Class A-1, Class A-2, and the payment  components of the
Class X Certificate will constitute "regular interests" in one of the REMICs and
the Class R Certificate will represent the sole class of "residual interests" in
each of the REMICs.

            This Pooling and Servicing  Agreement is dated as of October 1, 1999
(the  "Agreement"),  among ASSET BACKED FUNDING  CORPORATION,  as depositor (the
"Depositor"), PAN AMERICAN BANK, FSB, as seller (in such capacity, the "Seller")
and master servicer (in such capacity, the "Master Servicer"), FAIRBANKS CAPITAL
CORP.,  as special  servicer (in such  capacity,  the "Special  Servicer"),  and
BANKERS TRUST COMPANY OF CALIFORNIA, N.A., as trustee (the "Trustee").

                             PRELIMINARY STATEMENT:

          The Depositor intends to sell pass-through certificates (collectively,
the  "Certificates"),  to be issued hereunder in multiple classes,  which in the
aggregate will evidence the entire  beneficial  ownership  interest in the Trust
Fund  created  hereunder.  The  Certificates  will  consist  of four  classes of
certificates,  designated as (i) the Class A-1 Certificates,  (ii) the Class A-2
Certificates, (iii) the Class X Certificate and (iv) the Class R Certificates.

          As provided  herein,  the  Trustee  will make an election to treat the
assets  of the Trust  Fund  other  than the  Pre-Funding  Accounts,  Capitalized
Interest  Accounts  and the  rights  of Class A  Certificateholders  to  receive
payments  in respect of their  related  Interest  Carryover,  as three  separate
REMICs (as defined  herein) for federal income tax purposes.  For federal income
tax  purposes  the  Class A  Certificates  and  Class X  Certificates  represent
beneficial interests in the "regular interests" in REMIC III and the Class R-III
Component  represents  the sole class of  "residual  interest"  in REMIC III for
purposes of the REMIC  Provisions.  The Class R-I Component  represents the sole
class of "residual interest" in REMIC I and the Class R-II Component  represents
the sole class of  "residual  interest"  in REMIC II for  purposes  of the REMIC
Provisions.  There  are also  six  classes  of  uncertificated  REMIC I  Regular
Interests  issued under this  Agreement  (the Class LT1,  Class LT2,  Class LT3,
Class LT4,  Class LT5 and Class LT6  Interests),  each of which will  constitute
regular  interests  in REMIC I. There are also eight  classes of  uncertificated
REMIC II Regular  Interests  issued under this  Agreement  (the Class MT1, Class
MT2,  Class MT3,  Class MT4,  Class  MT5,  Class MT6,  Class MTN2 and Class MTN5
Interests),  each of which will  constitute  regular  interests in REMIC II. The
REMIC I  Regular  Interests  will be held as assets of REMIC II and the REMIC II
Regular  Interests  will be  held  as  assets  of  REMIC  III.  In  addition  to
representing  beneficial  interests  in  the  corresponding  REMIC  III  Regular
Interests,  the Class A Certificates  represent the right to receive payments in
respect  of  their   related   Interest   Carryovers   from  amounts   otherwise
distributable to the Class X  Certificateholders.  The Class X Certificates also
represent  beneficial  interests in the corresponding  Class X Regular Interest,
subject  to the  obligation  to make  payments  to the Class A  Certificates  in

recorded;  PROVIDED,  HOWEVER,  the  Seller  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 Seller to the
Trustee,  the Certificate  Insurer and the Rating  Agencies,  the recordation of
such  assignment  is not  necessary  to protect  the  Trustee's  interest in the
related  Mortgage Loan. The Seller shall be required to deliver such Assignments
for recording  within 30 days of the Closing Date.  The Seller shall furnish the
Trustee,  or its designated  agent,  with a copy of each  assignment of Mortgage
submitted  for  recording.  In the  event  that any such  Assignment  is lost or
returned unrecorded because of a defect therein,  the Seller shall promptly have
a substitute  Assignment prepared or have such defect cured, as the case may be,
and thereafter cause each such Assignment to be duly recorded. In the event that
any  Mortgage  Note is  endorsed  in  blank  as of the  Closing  Date,  promptly
following  the  Closing  Date  the  Seller  shall  cause  to be  completed  such
endorsements "Pay to the order of Bankers Trust Company of California,  N.A., as
Trustee under the Pooling and Servicing Agreement,  dated as of October 1, 1999,
United PanAm Mortgage Loan Trust 1999-2, Series 1999-2, without recourse."

          The Depositor herewith delivers to the Trustee an executed copy of the
Mortgage Loan Purchase Agreement.

          In addition,  on or prior to the Closing Date,  the Seller shall cause
the Certificate Insurer and the PMI Insurer to deliver the Certificate Insurance
Policy and the PMI Policy, respectively, to the Trustee.

          The Master Servicer shall forward to the Custodian  original documents
evidencing  an  assumption,  modification,  consolidation  or  extension  of any
Mortgage Loan entered into in accordance with this Agreement within two weeks of
their execution;  provided,  however, that the Master Servicer shall provide the
Custodian  with a  certified  true  copy  of any  such  document  submitted  for
recordation within two weeks of its execution, and shall provide the original of
any document  submitted for recordation or a copy of such document  certified by
the appropriate  public  recording  office to be a true and complete copy of the
original  within 270 days of its submission for  recordation.  In the event that
the Master  Servicer  cannot  provide a copy of such  document  certified by the
public  recording  office within such 270 day period,  the Master Servicer shall
deliver to the Custodian,  within such 270 day period, an Officer's  Certificate
of the Master Servicer which shall (A) identify the recorded document, (B) state
that the recorded document has not been delivered to the Custodian due solely to
a delay  caused by the  public  recording  office,  (C) state the amount of time
generally  required by the  applicable  recording  office to record and return a
document  submitted  for  recordation,  if known,  and (D)  specify the date the
applicable  recorded  document is expected to be delivered to the Custodian,  if
known,  and,  upon  receipt of a copy of such  document  certified by the public
recording office, the Master Servicer shall immediately deliver such document to
the Custodian.  In the event the appropriate  public  recording  office will not
certify as to the accuracy of such document, the Master Servicer shall deliver a
copy of such  document  certified  by an officer of the Master  Servicer to be a
true and complete copy of the original to the Custodian.

          Section 2.02 ACCEPTANCE BY TRUSTEE.

          The  Trustee  acknowledges  the receipt of the  Certificate  Insurance
Policy and the PMI Policy and,  subject to the  provisions  of Section  2.01 and
subject to the review  described below and any exceptions noted on the exception
report  described in the next  paragraph  below,  the  documents  referred to in
Section 2.01 above and all other  assets  included in the  definition  of "Trust
Fund" and  declares  that it holds and will  hold such  documents  and the other
documents  delivered to it  constituting  a Mortgage  File, and that it holds or
will hold all such assets and such other assets  included in the  definition  of
"Trust  Fund" in trust for the  exclusive  use and  benefit of all  present  and
future Certificateholders, and the Certificate Insurer.

          The Trustee agrees, for the benefit of the  Certificateholders and the
Certificate  Insurer  to  review,  or  that it has  reviewed  (or to  cause  the
Custodian to review or that it has caused the Custodian to have  reviewed)  each
Mortgage  File on or prior to the Closing Date (or, with respect to any document
delivered  after the Startup Day,  within 45 days of receipt and with respect to
any Qualified  Substitute  Mortgage  Loan,  within 45 days after the  assignment
thereof).  The Trustee further agrees, for the benefit of the Certificateholders
and the  Certificate  Insurer,  to certify in  substantially  the form  attached
hereto as Exhibit G-1,  within 45 days after the Closing Date (or,  with respect
to any document  delivered  after the Startup Day, within 45 days of receipt and
with  respect to any  Qualified  Substitute  Mortgage,  within 45 days after the
assignment  thereof)  that, as to each Mortgage Loan listed in the Mortgage Loan
Schedule  (other  than  any  Mortgage  Loan  paid in full or any  Mortgage  Loan
specifically  identified in the exception  report  annexed  thereto as not being
covered by such certification), (i) all documents required to be delivered to it
pursuant  Section  2.01 of  this  Agreement  are in its  possession,  (ii)  such
documents have been reviewed by it and have not been mutilated,  damaged or torn
and relate to such Mortgage Loan and (iii) based on its  examination and only as
to the foregoing,  the  information set forth in the Mortgage Loan Schedule that
corresponds  to items  (i) and (ii) of the  Mortgage  Loan  Schedule  accurately
reflects  information set forth in the Mortgage File. It is herein  acknowledged
that, in conducting such review,  the Trustee (or the Custodian,  as applicable)
is under no duty or obligation to inspect, review or examine any such documents,
instruments,  certificates  or other papers to determine  that they are genuine,
enforceable,  or  appropriate  for the  represented  purpose  or that  they have
actually  been  recorded or that they are other than what they  purport to be on
their face.

          Prior to the first  anniversary  date of this  Agreement  the  Trustee
shall deliver (or cause the Custodian to deliver) to the  Depositor,  the Master
Servicer and the Certificate  Insurer a final  certification in the form annexed
hereto as Exhibit G-2 evidencing the  completeness of the Mortgage  Files,  with
any applicable exceptions noted thereon.

          If in the  process  of  reviewing  the  Mortgage  Files and  making or
preparing, as the case may be, the certifications referred to above, the Trustee
(or the Custodian, as applicable) finds any document or documents constituting a
part of a Mortgage File to be missing or defective in any material  respect,  at
the  conclusion  of its  review the  Trustee  shall so notify  the  Seller,  the
Depositor,  the Master Servicer and the Certificate  Insurer. In addition,  upon
the discovery by the Seller,  Depositor or the Master  Servicer (or upon receipt
by the Trustee of written notification of such breach) of a breach of any of the
representations  and warranties made by the Seller in the related  Mortgage Loan
Purchase  Agreement in respect of any Mortgage Loan which  materially  adversely
affects such Mortgage Loan or the interests of the related Certificateholders in
such Mortgage Loan, the party  discovering such breach shall give prompt written
notice to the other parties to this Agreement and the Certificate Insurer.

          The Depositor and the Trustee  intend that the assignment and transfer
herein  contemplated  constitute  a sale  of the  Mortgage  Loans,  the  related
Mortgage Notes and the related documents,  conveying good title thereto free and
clear of any liens and encumbrances,  from the Depositor to the Trustee and that
such property not be part of the Depositor's estate or property of the Depositor
in the  event  of any  insolvency  by the  Depositor.  In the  event  that  such
conveyance is deemed to be, or to be made as security  for, a loan,  the parties
intend that the Depositor  shall be deemed to have granted and does hereby grant
to the  Trustee  a first  priority  perfected  security  interest  in all of the
Depositor's  right, title and interest in and to the Mortgage Loans, the related
Mortgage  Notes  and the  related  documents,  and  that  this  Agreement  shall
constitute a security agreement under applicable law.

          Section  2.03  REPURCHASE  OR  SUBSTITUTION  OF MORTGAGE  LOANS BY THE
SELLER.

          (a) With  respect to any Mortgage  Loan that has been  converted to an
REO Property,  all  references in this Section 2.03 to "Mortgage  Loan" shall be
deemed to refer to such REO Property. With respect to any Mortgage Loan that the
Seller is required to repurchase that is or becomes a Liquidated  Mortgage Loan,
in lieu of  repurchasing  such Mortgage Loan, the Seller shall deposit an amount
equal to the amount of the Realized  Loss, if any,  incurred in connection  with
the  liquidation  of such Mortgage Loan within the same time period in which the
Seller would have otherwise been required to repurchase such Mortgage Loan.

          (b) Upon  discovery  or receipt of  written  notice of any  materially
defective document in, or that a document is missing from, a Mortgage File or of
the breach by the Seller of any  representation,  warranty or covenant under the
Mortgage Loan  Purchase  Agreement or in Section 2.04 in respect of any Mortgage
Loan which materially  adversely  affects the value of such Mortgage Loan or the
interest  therein of the  Certificateholders,  or the Certificate  Insurer,  the
Trustee shall  promptly  notify the Seller,  the  Certificate  Insurer,  and the
Master Servicer of such defect,  missing document or breach and request that the
Seller  deliver  such missing  document or cure such defect or breach  within 90
days from the date the Seller was notified of such missing  document,  defect or
breach,  and if the Seller does not deliver such  missing  document or cure such
defect or breach in all material respects during such period,  the Trustee shall
enforce the Seller's  obligation under the Mortgage Loan Purchase  Agreement and
cause the Seller to  repurchase  such  Mortgage  Loan from the Trust Fund at the
Purchase Price on or prior to the Determination Date following the expiration of
such 90 day period (subject to Section 2.03(e), such enforcement to be commenced
by  providing  written  notice to Seller  within 30 days of the date  Seller was
obligated to cure such defect or breach);  PROVIDED that, in connection with any
such breach that could not reasonably have been cured within such 90 day period,
if the Seller  shall  have  commenced  to cure such  breach  within  such 90 day
period,  the Seller  shall be  permitted to proceed  thereafter  diligently  and
expeditiously  to cure the same within the additional  period provided under the
Mortgage  Loan  Purchase  Agreement.  The  Purchase  Price  for the  repurchased
Mortgage  Loan shall be deposited in the  Collection  Account,  and the Trustee,
upon receipt of written  certification from the Master Servicer of such deposit,
shall  release to the Seller the  related  Mortgage  File and shall  execute and
deliver  such  instruments  of  transfer  or  assignment,  in each case  without
recourse, as the Seller shall furnish to it and as shall be necessary to vest in
the Seller any Mortgage Loan released pursuant hereto and the Trustee shall have
no further responsibility with regard to such Mortgage File (it being understood
that the Trustee shall have no responsibility for determining the sufficiency of
such  assignment for its intended  purpose).  In lieu of  repurchasing  any such
Mortgage Loan as provided above, the Seller may cause such Mortgage Loan and, if
applicable,  any primary mortgage loan insurance covering such Mortgage Loan, to
be removed from the Trust Fund (in which case such  Mortgage Loan shall become a
Deleted Mortgage Loan) and substitute one or more Qualified  Substitute Mortgage
Loans in the manner and subject to the limitations set forth in Section 2.03(d).
It is  understood  and agreed  that the  obligation  of the Seller to cure or to
repurchase  (or to  substitute  for) any Mortgage Loan as to which a document is
missing, a material defect in a constituent  document exists or as to which such
a breach has occurred and is continuing shall constitute the sole remedy against
the Seller  respecting such omission,  defect or breach available to the Trustee
on  behalf  of the  Certificateholders,  the PMI  Insurer  and  the  Certificate
Insurer.

          (c) [Reserved]

          (d) Within 90 days of the earlier of discovery by the Master  Servicer
or receipt of notice by the Master Servicer of the breach of any representation,
warranty  or  covenant of the Master  Servicer  set forth in Section  2.05 which
materially and adversely affects the interests of the Certificateholders, or the
Certificate  Insurer in any Mortgage Loan,  the Master  Servicer shall cure such
breach in all material respects.

          (e) Any  substitution  of  Qualified  Substitute  Mortgage  Loans  for
Deleted  Mortgage Loans made pursuant to Section  2.03(a) must be effected prior
to the last  Business Day that is within two years after the Closing Date. As to
any  Deleted  Mortgage  Loan  for  which  the  Seller  substitutes  a  Qualified
Substitute  Mortgage Loan or Loans, such  substitution  shall be effected by the
Seller delivering to the Trustee, for such Qualified Substitute Mortgage Loan or
Loans, the Mortgage Note, the Mortgage,  the Assignment to the Trustee, and such
other documents and agreements,  with all necessary endorsements thereon, as are
required by Section 2.01, together with an Officers'  Certificate providing that
each such Qualified  Substitute  Mortgage Loan satisfies the definition  thereof
and specifying the  Substitution  Adjustment  (as described  below),  if any, in
connection with such  substitution.  The Trustee shall  acknowledge  receipt for
such Qualified  Substitute  Mortgage Loan or Loans and, within ten Business Days
thereafter, shall review such documents as specified in Section 2.02 and deliver
to the  Master  Servicer,  and the  Certificate  Insurer,  with  respect to such
Qualified  Substitute  Mortgage Loan or Loans, a certification  substantially in
the form attached  hereto as Exhibit G-1, with any applicable  exceptions  noted
thereon. Within one year of the date of substitution,  the Trustee shall deliver
to the Master Servicer and the Certificate Insurer a certification substantially
in the form of Exhibit  G-2 hereto  with  respect to such  Qualified  Substitute
Mortgage Loan or Loans,  with any applicable  exceptions noted thereon.  Monthly
Payments due with respect to Qualified Substitute Mortgage Loans in the month of
substitution  are not part of the Trust Fund and will be retained by the Seller.
For the month of substitution,  distributions to Certificateholders will reflect
the collections  and recoveries in respect of such Deleted  Mortgage Loan in the
Due Period  preceding the month of substitution and the Depositor or the Seller,
as the  case  may be,  shall  thereafter  be  entitled  to  retain  all  amounts
subsequently received in respect of such Deleted Mortgage Loan. The Seller shall
give or cause to be given  written  notice  to the  Certificateholders,  and the
Certificate  Insurer that such  substitution  has taken  place,  shall amend the
Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from
the terms of this  Agreement and the  substitution  of the Qualified  Substitute
Mortgage  Loan or Loans and shall  deliver a copy of such amended  Mortgage Loan
Schedule to the Trustee and the  Certificate  Insurer.  Upon such  substitution,
such Qualified  Substitute  Mortgage Loan or Loans shall  constitute part of the
Mortgage  Pool  and  shall  be  subject  in all  respects  to the  terms of this
Agreement  and,  in the  case of a  substitution  effected  by the  Seller,  the
Mortgage  Loan  Purchase  Agreement,  including,  in the case of a  substitution
effected by the Seller all applicable  representations  and  warranties  thereof
included  in  the  Mortgage   Loan  Purchase   Agreement   and  all   applicable
representations  and warranties  thereof set forth in Section 2.04, in each case
as of the date of substitution.

          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 will determine the amount (the "Substitution  Adjustment"),  if any, by
which the aggregate  Purchase  Price of all such Deleted  Mortgage Loans exceeds
the  aggregate,  as to each such  Qualified  Substitute  Mortgage  Loan,  of the
principal  balance  thereof as of the date of  substitution,  together  with one
month's interest on such principal  balance at the applicable  Mortgage Rate. On
the date of such substitution,  the Seller will deliver or cause to be delivered
to the Master Servicer for deposit in the Collection  Account an amount equal to
the  Substitution  Adjustment,  if any,  and the  Trustee,  upon  receipt of the
related  Qualified  Substitute  Mortgage Loan or Loans and  certification by the
Master  Servicer  of such  deposit,  shall  release to the  Seller  the  related
Mortgage  File or Files  and shall  execute  and  deliver  such  instruments  of
transfer or  assignment,  in each case  without  recourse,  as the Seller  shall
deliver to it and as shall be  necessary  to vest  therein any Deleted  Mortgage
Loan  released  pursuant  hereto.  In addition,  the Trustee shall assign to the
Seller any of the  Trustee's  rights under the PMI Policy in respect of any such
Deleted Mortgage Loan released to the Seller.

          (f) Upon discovery by the Seller, the Master Servicer, the Certificate
Insurer or the Trustee that any Mortgage  Loan does not  constitute a "qualified
mortgage"  within  the  meaning  of Section  860G(a)(3)  of the Code,  the party
discovering such fact shall within two Business Days give written notice thereof
to the other parties and the Certificate Insurer. In connection  therewith,  the
Seller shall  repurchase  or,  subject to the  limitations  set forth in Section
2.03(d),  substitute  one or more  Qualified  Substitute  Mortgage Loans for the
affected  Mortgage Loan within 90 days of the earlier of discovery or receipt of
such notice with respect to such affected  Mortgage Loan. Any such repurchase or
substitution  shall be made in the same manner as set forth in Section  2.03(a),
if made by the Seller.  The Trustee  shall  reconvey to the Seller the  Mortgage
Loan to be released  pursuant  hereto in the same manner,  and on the same terms
and  conditions,  as it  would a  Mortgage  Loan  repurchased  for  breach  of a
representation or warranty.

          Section 2.04 REPRESENTATIONS AND WARRANTIES OF THE SELLER WITH RESPECT
TO THE MORTGAGE LOANS.

          The Seller  hereby  represents  and  warrants  to the  Trustee for the
benefit of the  Certificateholders  and the Certificate  Insurer that, as of the
Closing  Date  or as of  such  other  date  specifically  provided  herein,  the
representations  and warranties  made by the Seller  pursuant to Section 3.01 of
the Mortgage  Loan  Purchase  Agreement are hereby being made to the Trustee and
are true and correct as of the Closing Date.

          With respect to the  representations  and warranties  incorporated  in
this Section  2.04 that are made to the best of the Seller's  knowledge or as to
which the Seller has no knowledge,  if it is discovered  by the  Depositor,  the
Seller,  the Master  Servicer,  the Certificate  Insurer or the Trustee 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
interest  therein of the  Certificateholders,  or the Certificate  Insurer then,
notwithstanding  the Seller's lack of knowledge with respect to the substance of
such representation and warranty being inaccurate at the time the representation
or warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty.

          Within  ninety days of its  discovery  or its receipt of notice of any
such  missing or  materially  defective  documentation  or any such  breach of a
representation  or  warranty,  the Seller  shall  promptly  deliver such missing
document or cure such defect or breach in all material respects, or in the event
such defect or breach cannot be cured,  the Seller shall repurchase the affected
Mortgage Loan or cause the removal of such Mortgage Loan from the Trust Fund and
substitute for it one or more Qualified  Substitute  Mortgage  Loans,  in either
case, in accordance with Section 2.03.

          It is understood  and agreed that the  representations  and warranties
incorporated  in this Section 2.04 shall survive  delivery of the Mortgage Files
to the Trustee and shall inure to the benefit of the  Certificateholders and the
Certificate Insurer  notwithstanding any restrictive or qualified endorsement or
assignment.  Upon discovery by any of the Depositor,  the Master  Servicer,  the
Special Servicer,  the Seller or the Trustee of a breach of any of the foregoing
representations  and warranties which materially and adversely affects the value
of any Mortgage Loan or the interests therein of the Certificateholders,  or the
Certificate Insurer, the party discovering such breach shall give prompt written
notice to the other parties and the Certificate  Insurer,  and in no event later
than two Business Days from the date of such  discovery.  It is  understood  and
agreed that the  obligations of the Seller set forth in Section 2.03(a) to cure,
substitute  for or  repurchase a Mortgage  Loan  pursuant to the  Mortgage  Loan
Purchase   Agreement   constitute   the   sole   remedies   available   to   the
Certificateholders,  the  Certificate  Insurer or to the Trustee on their behalf
respecting a breach of the representations  and warranties  incorporated in this
Section 2.04.

          Section 2.05  REPRESENTATIONS,  WARRANTIES AND COVENANTS OF THE MASTER
SERVICER.

          The Master Servicer hereby  represents,  warrants and covenants to the
Trustee, for the benefit of each of the Trustee, the Certificate Insurer and the
Certificateholders  and to the  Depositor  that as of the Closing  Date or as of
such date specifically provided herein:

          (i) The Master Servicer is duly organized,  validly  existing,  and in
     good standing under the laws of the  jurisdiction  of its formation and has
     all licenses  necessary to carry on its business as now being conducted and
     is  licensed,  qualified  and in  good  standing  or is  exempt  from  such
     licensure,  qualification  or  requirement  of good  standing in the states
     where the  Mortgaged  Property is located if the laws of such state require
     licensing  or  qualification  in  order  to  conduct  business  of the type
     conducted by the Master Servicer or is a condition to the enforceability or
     validity  of each  Mortgage  Loan;  the Master  Servicer  has the power and
     authority  to  execute  and  deliver  this  Agreement  and  to  perform  in
     accordance  herewith;  the  execution,  delivery  and  performance  of this
     Agreement  (including all instruments of transfer to be delivered  pursuant
     to this  Agreement)  by the Master  Servicer  and the  consummation  of the
     transactions  contemplated  hereby have been duly and  validly  authorized;
     this Agreement constitutes the valid, binding and enforceable obligation of
     the  Master  Servicer,   subject  to  applicable  bankruptcy,   insolvency,
     reorganization,  moratorium or other similar laws affecting the enforcement
     of creditors' rights generally or the rights of federally insured financial
     institutions;  and all  requisite  corporate  action  has been taken by the
     Master  Servicer to make this  Agreement  valid and binding upon the Master
     Servicer in accordance with its terms;

          (ii)  The  consummation  of  the  transactions  contemplated  by  this
     Agreement are in the ordinary course of business of the Master Servicer and
     will not result in the breach of any term or  provision  of the  charter or
     by-laws  of the  Master  Servicer  or result  in the  breach of any term or
     provision  of, or conflict  with or constitute a default under or result in
     the acceleration of any obligation under, any agreement,  indenture or loan
     or credit agreement or other instrument to which the Master Servicer or its
     property  is  subject,  or  result  in  the  violation  of any  law,  rule,
     regulation,  order,  judgment or decree to which the Master Servicer or its
     property is subject;

          (iii) The  execution  and  delivery  of this  Agreement  by the Master
     Servicer  and the  performance  and  compliance  with its  obligations  and
     covenants  hereunder  do  not  require  the  consent  or  approval  of  any
     governmental  authority or, if such consent or approval is required, it has
     been obtained;

          (iv) This Agreement,  and all documents and  instruments  contemplated
     hereby which are executed and delivered by the Master Servicer,  constitute
     and will  constitute  valid,  legal and binding  obligations  of the Master
     Servicer,  enforceable in accordance with their respective terms, except as
     the   enforcement   thereof  may  be  limited  by  applicable   bankruptcy,
     insolvency, reorganization,  moratorium or other similar laws affecting the
     enforcement of creditors' rights  generally,  or the rights of creditors of
     federally insured financial institutions, and general principles of equity;

          (v) [Reserved];

          (vi) The Master Servicer does not believe, nor does it have any reason
     or cause to  believe,  that it  cannot  perform  each  and  every  covenant
     contained in this Agreement;

          (vii) There is no action,  suit,  proceeding or investigation  pending
     or, to its knowledge,  threatened  against the Master Servicer that, either
     individually  or in the  aggregate,  (A) could  reasonably  be  expected to
     prohibit  or  materially  and  adversely  affect  the  performance  by such
     Servicer of its obligations  under, or validity or enforceability  of, this
     Agreement,  or (B) could  reasonably  be expected to result in any material
     impairment  of the right or ability of the Master  Servicer to carry on its
     business  substantially  as now  conducted,  or  (C)  could  reasonably  be
     expected  to result in any  material  liability  on the part of the  Master
     Servicer, or (D) would draw into question the validity or enforceability of
     this Agreement or of any action taken or to be taken in connection with the
     obligations  of the  Master  Servicer  contemplated  herein,  or (E)  would
     otherwise be likely to impair materially the ability of the Master Servicer
     to perform under the terms of this Agreement;

          (viii) Neither this Agreement nor any  information,  certificate of an
     officer,  statement furnished in writing or report delivered to the Trustee
     by the Master  Servicer in connection  with the  transactions  contemplated
     hereby contains any untrue statement of a material fact;

          (ix) The Master Servicer (a) acknowledges  that its performance  under
     this Agreement  will be adversely  affected if it is unable to become "Year
     2000 Compliant" prior to January 1, 2000, (b) has made an assessment of the
     microchip  and  computer-based  systems,   hardware,   software  and  other
     equipment used by the Master Servicer in connection  with such  performance
     (collectively,  "Systems")  and (c) confirms  that it has  developed and is
     implementing  a program to help assure  that its Systems  will be Year 2000
     Compliant by January 1, 2000. As used herein,  "Year 2000 Compliant"  means
     (1) the Systems  process,  provide and/or  receive  (provided data received
     from third  party  providers  is Year 2000  Compliant),  so as to avoid the
     occurrence  of a material  adverse  effect  thereon,  date data  (including
     without limitation calculating,  comparing, and sequencing),  within, from,
     into, and between centuries, including leap year calculations, and (2) none
     of  the  performance  or  the   functionality  or  the  Master   Servicer's
     performance under this Agreement will be materially  adversely  affected by
     dates prior to, on or after January 1, 2000; and

          (x) The  information  set  forth in the  Prepayment  Premium  Schedule
     relating to Prepayment  Premiums (including the Prepayment Premium Schedule
     attached thereto) is complete, true and correct in all material respects on
     the date or dates when such  information  is furnished and each  Prepayment
     Premium is permissible and enforceable in accordance with its terms (except
     to the extent that the enforceability thereof may be limited by bankruptcy,
     insolvency,  moratorium,  receivership  and other  similar laws relating to
     creditors'  rights generally or the  collectability  thereof may be limited
     due to  acceleration  in connection  with a foreclosure)  under  applicable
     state law;

          (xi) The Master Servicer will not waive any Prepayment  Premium unless
     it is waived in accordance with the standard set forth in Section 3.07.

          It is understood and agreed that the  representations,  warranties and
covenants set forth in this Section 2.05 shall survive  delivery of the Mortgage
Files  to the  Trustee  and  shall  inure to the  benefit  of the  Trustee,  the
Depositor, the Certificate Insurer and the Certificateholders. Upon discovery by
any of the Depositor,  the Master Servicer,  the Special Servicer, the Seller or
the Trustee of a breach of any of the foregoing representations,  warranties and
covenants which materially and adversely  affects the value of any Mortgage Loan

the party  discovering  such breach shall give prompt  written notice (but in no
event later than two  Business  Days  following  such  discovery)  to the Master
Servicer, the Seller, the Certificate Insurer and the Trustee.

          If, within 90 days of the earlier of discovery by the Master  Servicer
or receipt of notice by the Master Servicer of the breach of the  representation
or covenant  of the Master  Servicer  set forth in Sections  2.05(x) or 2.05(xi)
above which materially and adversely affects the interests of the Holders of the
Certificates or the Certificate  Insurer in any Prepayment  Premium,  the Master
Servicer shall remedy such breach as follows:  (a) if the representation made by
the Master  Servicer  in  Section  2.05(x)  above is  breached  and a  Principal
Prepayment has occurred in the applicable Prepayment Period, the Master Servicer
shall pay the amount of the scheduled Prepayment Premium, for the benefit of the
Holders of the  Certificates  and the  Certificate  Insurer,  by depositing such
amount into the Collection  Account,  net of any amount previously  collected by
the Master  Servicer  or paid by the  Master  Servicer,  for the  benefit of the
Holders of  Certificates  or the  Certificate  Insurer,  in the  respect of such
Prepayment  Premium;  and (b) if the covenant of the Master  Servicer in Section
2.05(xi)  above is  breached,  the Master  Servicer  shall remedy such breach by
paying  the amount of the  Prepayment  Premium  as to which  such  covenant  was
breached, for the benefit of the Holders of the Certificates and the Certificate
Insurer, by depositing such amount into the Collection Account.

     equity);

          (ii) Immediately  prior to the sale and assignment by the Depositor to
     the Trustee on behalf of the Trust of each Mortgage Loan, the Depositor had
     good and marketable  title to each Mortgage Loan (insofar as such title was
     conveyed  to  it  by  the  Seller)   subject  to  no  prior  lien,   claim,
     participation  interest,  mortgage,  security interest,  pledge,  charge or
     other encumbrance or other interest of any nature;

     changes in the financial  condition,  earnings,  affairs or business of the
     Depositor or which might  materially and adversely affect the properties or

     seeking to prevent the issuance of the  Certificates or the consummation by

          Section 2.08 REPRESENTATIONS AND WARRANTIES OF THE SELLER.

          The Seller hereby represents and warrants to the Trust and the Trustee
on behalf of the  Certificateholders,  the Certificate Insurer and the Depositor
that as of the Closing Date or as of such date specifically provided herein:

          (i)  The  Seller  is  duly  organized,  validly  existing  and in good
     standing as a federal  savings bank and has the power and  authority to own
     its assets and to transact the  business in which it is currently  engaged.
     The Seller is duly qualified to do business and is in good standing in each
     jurisdiction  in which the  character of the business  transacted  by it or
     properties owned or leased by it requires such  qualification  and in which
     the failure to so qualify would have a material  adverse  effect on (a) its
     business,  properties,  assets or condition  (financial or other),  (b) the
     performance  of its  obligations  under  this  Agreement,  (c) the value or
     marketability of the Mortgage Loans, or (d) its ability to foreclose on the
     related Mortgaged Properties to the extent such foreclosure is conducted by
     the Master Servicer.

          (ii) The Seller has the power and authority to make, execute,  deliver
     and  perform  this  Agreement  and to  consummate  all of the  transactions
     contemplated  hereunder and has taken all necessary action to authorize the
     execution,  delivery and performance of this  Agreement.  When executed and
     delivered,  this Agreement will  constitute the Seller's  legal,  valid and
     binding  obligations  enforceable in accordance  with its terms,  except as
     enforcement  of such terms may be limited  by (1)  bankruptcy,  insolvency,
     reorganization,  receivership,  moratorium  or similar laws  affecting  the
     enforcement of creditors'  rights  generally and the rights of creditors of
     federally  insured  financial  institutions  and  by  the  availability  of
     equitable  remedies,  (2) general equity principles  (regardless of whether
     such  enforcement is considered in a proceeding in equity or at law) or (3)
     public policy considerations  underlying the securities laws, to the extent
     that such policy  considerations limit the enforceability of the provisions
     of this Agreement which purport to provide  indemnification from securities
     laws liabilities.

          (iii)  The  Seller  holds all  necessary  licenses,  certificates  and
     permits from all  governmental  authorities  necessary for  conducting  its
     business as it is  presently  conducted.  It is not  required to obtain the
     consent  of  any  other  party  or  any  consent,   license,   approval  or
     authorization  from, or registration or declaration  with, any governmental
     authority,  bureau or agency in connection  with the  execution,  delivery,
     performance,  validity or enforceability of this Agreement, except for such
     consents,  licenses,  approvals  or  authorizations,  or  registrations  or
     declarations  as shall  have been  obtained  or filed,  as the case may be,
     prior to the Closing Date.

          (iv) The execution,  delivery and performance of this Agreement by the
     Seller will not  conflict  with or result in a breach of, or  constitute  a
     default under, any provision of any existing law or regulation or any order
     or decree of any court applicable to the Seller or any of its properties or
     any provision of its articles of incorporation or by-laws,  or constitute a
     material  breach of, or result in the creation or  imposition  of any lien,
     charge or encumbrance upon any of its properties  pursuant to any mortgage,
     indenture,  contract or other  agreement to which it is a party or by which
     it may be bound.

          (v) No certificate of an officer,  written statement or written report
     delivered  pursuant to the terms  hereof by the Seller  contains any untrue
     statement of a material fact or omits to state any material fact  necessary
     to make the certificate, statement or report not misleading.

          (vi)  The  transactions  contemplated  by  this  Agreement  are in the
     ordinary course of the Seller's business.

          (vii)  The  Seller  is not  insolvent,  nor  will the  Seller  be made
     insolvent by the transfer of the Mortgage  Loans to the  Depositor,  nor is
     the Seller aware of any pending insolvency of the Seller.

          (viii)  The  Seller is not in  violation  of,  and the  execution  and
     delivery of this Agreement by it and its  performance  and compliance  with
     the terms of this  Agreement  will not  constitute a violation with respect
     to, any order or decree of any  court,  or any order or  regulation  of any
     federal, state, municipal or governmental agency having jurisdiction, which
     violation  would  materially  and adversely  affect the Seller's  financial
     condition  (financial  or  otherwise)  or  operations,  or  materially  and
     adversely affect the performance of any of its duties hereunder.

          (ix)  There are no actions  or  proceedings  against  the  Seller,  or
     pending or, to its knowledge,  threatened, before any court, administrative
     agency  or  other   tribunal;   nor,  to  its  knowledge,   are  there  any
     investigations (i) that, if determined adversely, would prohibit the Seller
     from entering into this Agreement, (ii) seeking to prevent the consummation
     of any of the transactions contemplated by this Agreement or (iii) that, if
     determined adversely, would prohibit or materially and adversely affect the
     Seller's ability to perform any of its respective obligations under, or the
     validity or enforceability of, this Agreement.

          (x) The Seller did not transfer the  Mortgage  Loans to the  Depositor
     with any intent to hinder, delay or defraud any of its creditors.

          (xi) The Seller  acquired  title to the Mortgage  Loans in good faith,
     without notice of any adverse claims.

          (xii) The transfer,  assignment  and  conveyance of the Mortgage Notes
     and the  Mortgages  by the Seller to the  Depositor  are not subject to the
     bulk  transfer  laws or any similar  statutory  provisions in effect in any
     applicable jurisdiction.

          Section 2.09 COVENANTS OF THE SELLER.

          The Seller hereby  covenants  that except for the transfer  hereunder,
the Seller will not sell,  pledge,  assign or transfer to any other  Person,  or
grant,  create,  incur, assume or suffer to exist any lien on any Mortgage Loan,
or any interest therein;  the Seller will notify the Trustee, as assignee of the
Depositor,  of the existence of any lien on any Mortgage Loan  immediately  upon
discovery  thereof,  and the Seller will defend the right, title and interest of
the Trust,  as assignee of the Depositor,  in, to and under the Mortgage  Loans,
against  all  claims of third  parties  claiming  through  or under the  Seller;
provided,  however, that nothing in this Section 2.09 shall prevent or be deemed
to prohibit the Seller from  suffering  to exist upon any of the Mortgage  Loans
any liens for municipal or other local taxes and other  governmental  charges if
such taxes or  governmental  charges shall not at the time be due and payable or
if the Seller shall  currently be contesting the validity  thereof in good faith
by  appropriate  proceedings  and shall  have set  aside on its  books  adequate
reserves with respect thereto.

          Section 2.10 ADDITIONAL TRANSFERS.

          (a) Subject to the satisfaction of the conditions set forth in Article
II hereof  and  paragraph  (b) below and  pursuant  to the terms of the  related
Additional  Transfer  Agreement,  in consideration of the Trustee's  delivery on
each  Additional  Transfer  Date to or upon the order of the  Seller of all or a
portion of the balance of funds in the related Pre-Funding  Account,  the Seller
shall on such  Additional  Transfer Date sell,  transfer,  assign,  set over and
otherwise  convey without  recourse to the Trustee,  all of the Seller's  right,
title and interest in and to each related Additional Mortgage Loan listed in the
Mortgage Loan Schedule delivered by the Seller on such Additional  Transfer Date
for  inclusion in the related Loan Group,  including  (i) the related  Principal
Balance,  all  interest  payments  due after the  related  Cut-off  Date and all
collections in respect of principal  received after such Cut-off Date;  (ii) any
real  property  that secured  such  Additional  Mortgage  Loan and that has been
acquired by  foreclosure or deed in lieu of  foreclosure;  (iii) its interest in
any insurance policies in respect of such Additional Mortgage Loan; and (iv) all
proceeds of the  foregoing  to the  Trustee.  The  transfer by the Seller to the
Trustee of the Additional Mortgage Loans set forth in the Mortgage Loan Schedule
shall be absolute and shall be intended by all parties hereto to be treated as a
sale  by the  Seller  to  the  Trust.  If the  assignment  and  transfer  of the
Additional  Mortgage Loans and the other property specified in this Section 2.10
from the Seller to the Trust pursuant to this Agreement is held or deemed not to
be a sale or is held or deemed to be a pledge of security for a loan, the Seller
intends  that the rights and  obligations  of the parties  shall be  established
pursuant to the terms of this Agreement and that, in such event,  (i) the Seller
shall be deemed to have  granted and does hereby grant to the Trustee as of each
Additional  Transfer Date a perfected,  first priority  security interest in the
entire right,  title and interest of the Seller in and to the related Additional
Mortgage Loans and all other property  conveyed to the Trustee  pursuant to this
Section 2.10 and all proceeds thereof,  and (ii) this Agreement shall constitute
a  security  agreement  under  applicable  law.  The  amount  released  from the
Pre-Funding  Account shall be one hundred percent (100%) of the aggregate of the
applicable Cut-off Date Principal  Balances of the Additional  Mortgage Loans so
transferred.

          (b) The Trustee shall withdraw from the  Pre-Funding  Account funds in
an amount equal to one hundred percent (100%) of the aggregate of the applicable
Cut-off Date Principal Balances of the Additional  Mortgage Loans so transferred
to the Trust and use such cash to  purchase  the  Additional  Mortgage  Loans on
behalf of the Trust,  along with the other property and rights  related  thereto
described  in  paragraph  (a) above  only upon the  satisfaction  of each of the
following conditions on or prior to each Additional Transfer Date:

          (i) the Seller  shall  have  provided  the  Trustee,  the  Certificate
     Insurer and the Rating Agencies with an Addition Notice, which notice shall
     be given not less than two Business Days prior to such Additional  Transfer
     Date and shall  designate the  Additional  Mortgage Loans to be sold to the
     Trust and the  aggregate  Cut-off Date  Principal  Balance of such Mortgage
     Loans;

          (ii) the Seller shall have deposited in the Collection Account (A) all
     principal collected after such Cut-off Date and interest payments due after
     such Cut-off  Date but  collected on or before such Cut-off Date in respect
     of each  Additional  Mortgage Loan and (B) the related  Additional  Cut-off
     Date Deposit;

          (iii) the Seller shall have delivered an Officer's  Certificate to the
     Trustee  confirming  that, as of each Additional  Transfer Date, the Seller
     was not insolvent, nor would it be made insolvent by such transfer, nor was
     it aware of any pending insolvency of the Seller;

          (iv) the Pre-Funding Period shall not have ended;

          (v) the  Seller  shall have  delivered  to the  Trustee  an  Officer's
     Certificate   confirming  the  satisfaction  of  each  condition  precedent
     specified  in this  paragraph  (b) and in the related  Additional  Transfer
     Agreement;

          (vi) the Seller shall have  delivered an Officer's  Certificate to the
     Trustee  confirming that the  representations  and warranties of the Seller
     pursuant  to Section  2.04  hereof  and  Section  2.08  hereof are true and
     correct with respect to the Seller and the Additional  Mortgage  Loans,  as
     applicable, as of the Additional Transfer Date;

          (vii)  the  Seller  shall  have  provided  the  Rating  Agencies,  the
     Certificate  Insurer and the Trustee with an Opinion of Counsel relating to
     the sale of the Additional Mortgage Loans to the Trustee;

          (viii) the Trust shall not purchase an Additional Mortgage Loan unless
     the Seller obtains the prior written consent of the Certificate Insurer and
     each Rating Agency,  which consent,  in the case of the Certificate Insurer
     shall be subject to the provisions of subsection (e) below;

          (ix) [reserved]; and

          (x) in connection  with the transfer and  assignment of the Additional
     Mortgage Loans, the Seller shall satisfy the document delivery requirements
     set forth in Section 2.01 hereof.

          (c) In  connection  with  each  Additional  Transfer  Date  and on the
related  Distribution  Date,  the  Trustee  shall  determine  (i) the amount and
correct  dispositions  of the Capitalized  Interest  Requirement and Pre-Funding
Earnings for such  Distribution  Date in accordance  with the provisions of this
Agreement  and  (ii)  any  other  necessary   matters  in  connection  with  the
administration  of the  related  Pre-Funding  Account and  Capitalized  Interest
Account.  In the event that any  amounts  are  released  by the  Trustee  from a
Pre-Funding  Account  or from a  Capitalized  Interest  Account  as a result  of
calculation  error,  the Trustee  shall not be liable  therefor,  and the Seller
shall immediately repay such amounts to the Trustee.

          (d) The Trustee shall acknowledge  receipt on each Additional Transfer
Date of the Additional  Mortgage  Loans  delivered to it on such date and within
five  Business  Days after such  receipt  shall,  as  specified  in Section 2.01
hereof,  review the documents  required to be delivered pursuant to Section 2.01
hereof (or shall cause such  documents to be reviewed)  and shall deliver to the
Seller,  the Depositor and the Master Servicer,  with respect to such Additional
Mortgage Loans, a certification substantially similar to the one prepared by the
Trustee  pursuant to the second  paragraph  of Section  2.02  hereof.  After the
delivery of each such  certification,  the Trustee  shall  provide to the Master
Servicer,  the Seller and the  Depositor,  no less  frequently  than  quarterly,
updated certifications,  indicating the then current status of exceptions to the
Mortgage  Files  of  the  related  Additional  Mortgage  Loans  until  all  such
exceptions have been eliminated.

          (e) With  respect to any  Additional  Transfer  Date which is at least
three weeks prior to the end of the Pre-Funding  Period, the Certificate Insurer
may condition its consent to the purchase of any  Additional  Mortgage  Loans on
retaining  the option to review,  for a period of two weeks from the  applicable
Additional Transfer Date, the applicable  Additional Mortgage Loans to determine
whether such Additional Mortgage Loans are Qualified  Additional Mortgage Loans.
Upon notification by the Certificate  Insurer to the Trustee and the Seller that
any such Additional  Mortgage Loan delivered by the Seller does not constitute a
"Qualified  Additional Mortgage Loan" within the meaning of this Agreement,  the
Seller shall, subject to the limitations  specified in the last sentence of this
Section 2.10(e),  repurchase such Additional Mortgage Loan at the Purchase Price
or substitute one or more Mortgage Loans which are acceptable to the Certificate
Insurer for the affected Additional Mortgage Loan, in each case on or before the
last day of the Pre-Funding Period. Any such repurchase or substitution shall be
made in the same  manner as set forth in  Section  2.03(a).  The  Trustee  shall
reconvey to the Seller the  Additional  Mortgage  Loan to be  released  pursuant
hereto in the same manner,  and on the same terms and conditions,  as it would a
Mortgage Loan  repurchased  for breach of a  representation  or warranty.  In no
event  shall the  Certificate  Insurer  require  the  Seller to  repurchase,  or
substitute for, Additional Mortgage Loans pursuant to this Section 2.10(e) in an
aggregate  amount  greater  than 10% of the  aggregate  Cut-off  Date  Principal
Balance of the Additional Mortgage Loans delivered on the applicable  Additional
Transfer Date.

          Section 2.11 MANDATORY PREPAYMENT.

          Any Unutilized  Pre-Funding  Amount shall be distributed to Holders of
the related  Certificate  Group in  accordance  with  Section 4.05 hereof on the
Distribution  Date immediately  following the Due Period in which the end of the
Pre-Funding Period occurs.


                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

          Section 3.01 MASTER SERVICER TO ACT AS SERVICER.

          The Master Servicer shall service and administer the Mortgage Loans on
behalf of the  Trustee and in the best  interests  of and for the benefit of the
Certificateholders  and the  Certificate  Insurer (as  determined  by the Master
Servicer  in its  reasonable  judgment)  in  accordance  with the  terms of this
Agreement and the Mortgage Loans and, to the extent  consistent with such terms,
in the same manner in which it services and administers  similar  mortgage loans
for its own portfolio, giving due consideration to customary and usual standards
of  practice  of  mortgage  lenders  and loan  servicers  administering  similar
mortgage loans but without regard to:

          (i) any relationship that the Master Servicer, any Sub-Servicer or any
     Affiliate  of the Master  Servicer  or any  Sub-Servicer  may have with the
     related Mortgagor;

          (ii) the ownership or  non-ownership  of any Certificate by the Master
     Servicer or any Affiliate of the Master Servicer;

          (iii) the Master  Servicer's  obligation to make Advances or Servicing
     Advances; or

          (iv)  the  Master   Servicer's,   the   Special   Servicer's   or  any
     Sub-Servicer's  right to receive compensation for its services hereunder or
     with respect to any particular transaction.

To the extent  consistent with the foregoing,  the Master Servicer shall seek to
maximize  the timely and  complete  recovery of  principal  and  interest on the
Mortgage Notes. Subject only to the above-described  servicing standards and the
terms of this  Agreement and of the Mortgage  Loans,  the Master  Servicer shall
have full power and authority, acting alone or through Sub-Servicers as provided
in Section 3.02, to do or cause to be done any and all things in connection with
such  servicing  and  administration  which it may deem  necessary or desirable.
Without limiting the generality of the foregoing, the Master Servicer in its own
name or in the name of a Sub-Servicer is hereby  authorized and empowered by the
Trustee when the Master Servicer believes it appropriate in its best judgment in
accordance with the servicing standards set forth above, to execute and deliver,
on behalf of the  Certificateholders  and the  Trustee,  and upon  notice to the
Trustee, 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 the Mortgaged Properties and to institute  foreclosure
proceedings  or  obtain a  deed-in-lieu  of  foreclosure  so as to  convert  the
ownership  of such  properties,  and to hold or cause  to be held  title to such
properties, on behalf of the Trustee and Certificateholders. The Master Servicer
shall service and administer the Mortgage  Loans in accordance  with  applicable
state and federal law and shall provide to the Mortgagors  any reports  required
to be provided to them  thereby.  The Master  Servicer  shall also comply in the
performance of this Agreement with all reasonable rules and requirements of each
insurer under any standard hazard insurance policy. Subject to Section 3.17, the
Trustee  shall  execute,  at the  written  request of the Master  Servicer,  and
furnish to the  Master  Servicer  and any  Sub-Servicer  any  special or limited
powers of attorney and other  documents  necessary or  appropriate to enable the
Master   Servicer  or  any   Sub-Servicer  to  carry  out  their  servicing  and
administrative  duties hereunder;  PROVIDED,  such limited powers of attorney or
other  documents  shall be prepared by the Master  Servicer and submitted to the
Trustee for  execution.  The Trustee  shall not be liable for the actions of the
Master Servicer or any Sub-Servicers under such powers of attorney.

          Subject to Section 3.09 hereof,  in  accordance  with the standards of
the  preceding  paragraph,  the  Master  Servicer  shall  advance or cause to be
advanced  funds as necessary for the purpose of effecting the timely  payment of
taxes and  assessments  on the Mortgaged  Properties,  which  advances  shall be
Servicing Advances  reimbursable in the first instance from related  collections
from the Mortgagors pursuant to Section 3.09, and further as provided in Section
3.11. Any cost incurred by the Master Servicer or by  Sub-Servicers in effecting
the timely payment of taxes and  assessments on a Mortgaged  Property shall not,
for the purpose of calculating distributions to Certificateholders,  be added to
the unpaid Principal Balance of the related Mortgage Loan,  notwithstanding that
the terms of such Mortgage Loan so permit.

          Notwithstanding anything in this Agreement to the contrary, the Master
Servicer  may not make any future  advances  with  respect  to a  Mortgage  Loan
(except as  provided  in Section  4.04) and the  Master  Servicer  shall not (i)
permit any modification  with respect to any Mortgage Loan that would change the
Mortgage Rate,  reduce or increase the Principal  Balance (except for reductions
resulting  from actual  payments of principal) or change the final maturity date
on such Mortgage Loan (unless,  as provided in Section 3.07, the Mortgagor is in
default with respect to the Mortgage Loan or such default is, in the judgment of
the Master Servicer,  reasonably  foreseeable) or (ii) permit any  modification,
waiver or amendment of any term of any Mortgage  Loan that would both (A) effect
an exchange or  reissuance  of such Mortgage Loan under Section 1001 of the Code
(or  Treasury  regulations  promulgated  thereunder)  and (B)  cause  any  REMIC
hereunder to fail to qualify as a REMIC under the Code or the  imposition of any
tax on "prohibited transactions" or "contributions after the startup date" under
the REMIC Provisions.

          The Master Servicer may, with the consent of the Certificate  Insurer,
delegate its responsibilities under this Agreement;  PROVIDED,  however, that no
such delegation shall release the Master Servicer from the  responsibilities  or
liabilities arising under this Agreement.

          Section 3.02  SUB-SERVICING  AGREEMENTS  BETWEEN  MASTER  SERVICER AND
SUB-SERVICERS.

          (a) The Master Servicer may enter into  Sub-Servicing  Agreements with
Sub-Servicers  for the  servicing  and  administration  of the  Mortgage  Loans;
PROVIDED,  HOWEVER, that any Sub-Servicer shall be acceptable to the Certificate
Insurer and  provided  such  agreements  would not result in a  withdrawal  or a
downgrading by any Rating Agency of the rating or any shadow rating on any Class
of Certificates. The Trustee is hereby authorized to acknowledge, at the request
of the Master Servicer, any Sub-Servicing  Agreement that meets the requirements
applicable to  Sub-Servicing  Agreements set forth in this Agreement and that is
otherwise permitted under this Agreement.  The Master Servicer hereby designates
Fairbanks Capital Corp. as the initial Sub-Servicer.

          Each Sub-Servicer  shall be (i) authorized to transact business in the
state or states  where the  related  Mortgaged  Properties  it is to service are
situated,  if and  to the  extent  required  by  applicable  law to  enable  the
Sub-Servicer  to perform its obligations  hereunder and under the  Sub-Servicing
Agreement and (ii) a Freddie Mac or Fannie Mae approved mortgage servicer.  Each
Sub-Servicing Agreement must impose on the Sub-Servicer  requirements conforming
to the  provisions  set forth in Section  3.08 and provide for  servicing of the
Mortgage Loans consistent with the terms of this Agreement.  The Master Servicer
will examine each  Sub-Servicing  Agreement  and will be familiar with the terms
thereof. The terms of any Sub-Servicing  Agreement will not be inconsistent with
any  of  the  provisions  of  this  Agreement.   The  Master  Servicer  and  the
Sub-Servicers may enter into and make amendments to the Sub-Servicing Agreements
or enter into different forms of Sub-Servicing  Agreements;  PROVIDED,  HOWEVER,
that any such  amendments or different  forms shall be  consistent  with and not
violate  the  provisions  of this  Agreement,  and  that no  such  amendment  or
different form shall be made or entered into which could be reasonably  expected
to be materially adverse to the interests of the Certificateholders  without the
consent of the Certificate  Insurer and the Holders of Certificates  entitled to
at least 66% of the Voting Rights;  PROVIDED,  FURTHER,  that the consent of the
Holders of Certificates  entitled to at least 66% of the Voting Rights shall not
be required (i) to cure any  ambiguity or defect in a  Sub-Servicing  Agreement,
(ii)  to  correct,  modify  or  supplement  any  provisions  of a  Sub-Servicing
Agreement,  or (iii) to make any other  provisions  with  respect  to matters or
questions  arising under a Sub-Servicing  Agreement,  which, in each case, shall
not be inconsistent with the provisions of this Agreement. Any variation without
the consent of the Certificate Insurer and the Holders of Certificates  entitled
to at least 66% of the Voting  Rights from the  provisions  set forth in Section
3.08 relating to insurance or priority  requirements of Sub-Servicing  Accounts,
or credits and charges to the Sub-Servicing Accounts or the timing and amount of
remittances by the Sub-Servicers to the Master Servicer, are conclusively deemed
to be  inconsistent  with this  Agreement and therefore  prohibited.  The Master
Servicer shall deliver to the Trustee and the Certificate  Insurer copies of all
Sub-Servicing Agreements,  and any amendments or modifications thereof, promptly
upon the Master Servicer's execution and delivery of such instruments.

          (b)  As  part  of  its  servicing  activities  hereunder,  the  Master
Servicer,  for  the  benefit  of the  Trustee,  the  Certificateholders  and the
Certificate  Insurer,  shall enforce the obligations of each Sub-Servicer  under
the related  Sub-Servicing  Agreement  and of the Seller under the Mortgage Loan
Purchase  Agreement,  including,  without  limitation,  any  obligation  to make
advances  in respect of  delinquent  payments  as  required  by a  Sub-Servicing
Agreement,  or to  purchase a Mortgage  Loan on account of missing or  defective
documentation  or on  account  of a  breach  of a  representation,  warranty  or
covenant, as described in Section 2.03(a). Such enforcement,  including, without
limitation,  the legal  prosecution  of  claims,  termination  of  Sub-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,  and  shall be  reimbursed  therefor  only (i) from a  general
recovery  resulting  from such  enforcement,  to the extent,  if any,  that such
recovery  exceeds all amounts due in respect of the related  Mortgage  Loans, or
(ii) from a specific recovery of costs,  expenses or attorneys' fees against the
party against whom such  enforcement  is directed.  Enforcement  of the Mortgage
Loan  Purchase  Agreement  against  the Seller  shall be  effected by the Master
Servicer to the extent it is not the  Seller,  and  otherwise  by the Trustee in
accordance with the foregoing provisions of this paragraph.

          Section 3.03 SUCCESSOR SUB-SERVICERS.

          The Master Servicer (with the consent of the  Certificate  Insurer) or
the  Certificate  Insurer  shall be  entitled  to  terminate  any  Sub-Servicing
Agreement and the rights and  obligations  of any  Sub-Servicer  pursuant to any
Sub-Servicing  Agreement in  accordance  with the terms and  conditions  of such
Sub-Servicing  Agreement.  In the event of termination of any Sub-Servicer,  all
servicing  obligations of such Sub-Servicer  shall be assumed  simultaneously by
the Master Servicer without any act or deed on the part of such  Sub-Servicer or
the Master  Servicer,  and the Master Servicer either shall service directly the
related  Mortgage  Loans or shall enter into a  Sub-Servicing  Agreement  with a
successor Sub-Servicer which qualifies under Section 3.02.

          Any  Sub-Servicing  Agreement  shall include the  provision  that such
agreement may be immediately  terminated by the Master Servicer, the Trustee (if
the Trustee is acting as Servicer) or the  Certificate  Insurer  without fee, in
accordance  with the  terms of this  Agreement,  in the  event  that the  Master
Servicer (or the Trustee,  if such party is then acting as Servicer)  shall, for
any reason,  no longer be the Master  Servicer  (including  termination due to a
Servicer Event of Termination).

          Section 3.04 LIABILITY OF THE MASTER SERVICER.

          Notwithstanding any Sub-Servicing  Agreement or the provisions of this
Agreement relating to agreements or arrangements between the Master Servicer and
a  Sub-Servicer  or  reference  to  actions  taken  through  a  Sub-Servicer  or
otherwise,  the Master Servicer shall remain  obligated and primarily  liable to
the  Trustee,  the  Certificateholders  and  the  Certificate  Insurer  for  the
servicing  and  administering  of the  Mortgage  Loans  in  accordance  with the
provisions of Section 3.01 without diminution of such obligation or liability by
virtue  of  such  Sub-Servicing  Agreements  or  arrangements  or by  virtue  of
indemnification  from the Sub-Servicer and to the same extent and under the same
terms  and  conditions  as if the  Master  Servicer  alone  were  servicing  and
administering the Mortgage Loans. The Master Servicer shall be entitled to enter
into  any  agreement  with a  Sub-Servicer  for  indemnification  of the  Master
Servicer by such  Sub-Servicer and nothing  contained in this Agreement shall be
deemed to limit or modify such indemnification.

          Section 3.05 NO CONTRACTUAL RELATIONSHIP BETWEEN SUB-SERVICERS AND THE
TRUSTEE OR CERTIFICATEHOLDERS.

          Any  Sub-Servicing   Agreement  that  may  be  entered  into  and  any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such shall be deemed to be between the  Sub-Servicer  and the
Master Servicer alone,  and the Trustee,  Certificateholders  or the Certificate
Insurer shall not be deemed  parties  thereto and shall have no claims,  rights,
obligations,  duties or liabilities with respect to the  Sub-Servicer  except as
set forth in Section 3.06.  The Master  Servicer  shall be solely liable for all
fees  owed  by it to  any  Sub-Servicer,  irrespective  of  whether  the  Master
Servicer's  compensation  pursuant to this  Agreement is  sufficient to pay such
fees.

          Section 3.06 ASSUMPTION OR TERMINATION OF SUB-SERVICING  AGREEMENTS BY
TRUSTEE.

          In the event the Master Servicer shall for any reason no longer be the
Master  Servicer  (including by reason of the  occurrence of a Servicer Event of
Termination),  the  Trustee  shall  thereupon  assume  all  of  the  rights  and
obligations of the Master Servicer under each  Sub-Servicing  Agreement that the
Master  Servicer may have entered into,  unless the Trustee (with the consent of
the  Certificate  Insurer) or the  Certificate  Insurer  elects to terminate any
Sub-Servicing  Agreement  in  accordance  with its terms as  provided in Section
3.03. Upon such  assumption,  the Trustee (or the successor  servicer  appointed
pursuant to Section  7.02)  shall be deemed,  subject to Section  3.03,  to have
assumed all of the  departing  Master  Servicer's  interest  therein and to have
replaced  the  departing  Master  Servicer  as a  party  to  each  Sub-Servicing
Agreement  to the  same  extent  as if each  Sub-Servicing  Agreement  had  been
assigned to the assuming  party,  except that (i) the departing  Master Servicer
shall  not  thereby  be  relieved  of any  liability  or  obligations  under any
Sub-Servicing  Agreement  that arose before it ceased to be the Master  Servicer
and (ii) neither the Trustee nor any successor  Master  Servicer shall be deemed
to have assumed any liability or  obligation  of the Master  Servicer that arose
before it ceased to be the Master Servicer.

          The Master  Servicer at its expense  shall,  upon  request of Trustee,
deliver  to the  assuming  party all  documents  and  records  relating  to each
Sub-Servicing  Agreement  and the  Mortgage  Loans  then being  serviced  and an
accounting  of amounts  collected  and held by or on behalf of it, and otherwise
use its best  efforts  to effect  the  orderly  and  efficient  transfer  of the
Sub-Servicing Agreements to the assuming party.

          Section 3.07 COLLECTION OF CERTAIN MORTGAGE LOAN PAYMENTS.

          The Master  Servicer  shall  make  reasonable  efforts to collect  all
payments  called for under the terms and provisions of the Mortgage  Loans,  and
shall, to the extent such procedures shall be consistent with this Agreement and
the terms and  provisions  of any  applicable  insurance  policies,  follow such
collection  procedures  as it  would  follow  with  respect  to  mortgage  loans
comparable to the Mortgage Loans and held for its own account.  Consistent  with
the  foregoing,  the Master  Servicer may in its  discretion  (i) waive any late
payment charge or, if applicable,  any penalty interest,  or (ii) extend the due
dates  for the  Monthly  Payments  due on a  Mortgage  Note for a period  of not
greater than 180 days; PROVIDED,  HOWEVER, that any extension pursuant to clause
(ii) above shall not affect the  amortization  schedule of any Mortgage Loan for
purposes of any  computation  hereunder,  except as provided  below and provided
further,  that the  Master  Servicer  shall  not waive  any  Prepayment  Premium
provision included in a Mortgage Note unless the Master Servicer determines,  in
its best  reasonable  judgment,  that the related  Mortgagor will be in imminent
default of all future  payments of principal and interest under the terms of the
related Mortgage Note. In the event of any such  arrangement  pursuant to clause
(ii) above, the Master Servicer shall make timely advances on such Mortgage Loan
during  such  extension  pursuant  to Section  4.04 and in  accordance  with the
amortization  schedule of such  Mortgage  Loan without  modification  thereof by
reason of such arrangement. Notwithstanding the foregoing, in the event that any
Mortgage  Loan is in default or, in the  judgment of the Master  Servicer,  such
default is reasonably  foreseeable,  the Master  Servicer,  consistent  with the
standards  set forth in Section  3.01,  may also waive,  modify or vary any term
(other  than  the  waiver  of any  Prepayment  Premium)  of such  Mortgage  Loan
(including  modifications  that would  change the  Mortgage  Rate,  forgive  the
payment of  principal  or  interest  or extend the final  maturity  date of such
Mortgage Loan), accept payment from the related Mortgagor of an amount less than
the Stated  Principal  Balance in final  satisfaction  of such Mortgage Loan, or
consent to the postponement of strict compliance with any such term or otherwise
grant  indulgence  to any Mortgagor  (any and all such  waivers,  modifications,
variances,  forgiveness of principal or interest,  postponements, or indulgences
collectively referred to herein as "forbearance"), PROVIDED, HOWEVER, that in no
event  shall the  Master  Servicer  grant any such  forbearance  (other  than as
permitted  by the  second  sentence  of this  Section)  with  respect to any one
Mortgage  Loan more than once in any 12 month  period or more than  three  times
over the life of such Mortgage Loan. The Master Servicer's  analysis  supporting
any forbearance  and the conclusion that any forbearance  meets the standards of
Section 3.01  (including  the standard that such  forbearance  will maximize the
timely and complete  recovery of principal  and interest on the Mortgage  Notes)
shall be reflected in writing in the Mortgage  File and shall be provided to the
Certificate  Insurer upon request.  Notwithstanding  the  foregoing,  the Master
Servicer  shall not  modify  the terms of  Mortgage  Loans  having an  aggregate
Principal  Balance in excess of 3.00% of the Cut-off  Date  Aggregate  Principal
Balance  of the  Related  Loan Group  without  the  consent  of the  Certificate
Insurer.

          Section 3.08 SUB-SERVICING ACCOUNTS.

          In those  cases where a  Sub-Servicer  is  servicing  a Mortgage  Loan
pursuant to a  Sub-Servicing  Agreement,  the  Sub-Servicer  will be required to
establish and maintain one or more accounts  (collectively,  the  "Sub-Servicing
Account").  The  Sub-Servicing  Account  shall be an Eligible  Account and shall
comply  with all  requirements  of this  Agreement  relating  to the  Collection
Account.  The  Sub-Servicer  shall  deposit in the clearing  account in which it
customarily  deposits  payments and  collections on mortgage loans in connection
with its mortgage loan  servicing  activities on a daily basis,  and in no event
more than one  Business  Day  after  the  Sub-Servicer's  receipt  thereof,  all
proceeds  of Mortgage  Loans  received by the  Sub-Servicer  less its  servicing
compensation to the extent permitted by the Sub-Servicing  Agreement,  and shall
thereafter deposit such amounts in the Sub-Servicing  Account,  in no event more
than two Business Days after the receipt of such amounts. The Sub-Servicer shall
thereafter  deposit  such  proceeds  in the  Collection  Account  or remit  such
proceeds to the Master Servicer for deposit in the Collection  Account not later
than two Business  Days after the deposit of such  amounts in the  Sub-Servicing
Account. For purposes of this Agreement,  the Master Servicer shall be deemed to
have received payments on the Mortgage Loans when the Sub-Servicer receives such
payments.

          Section  3.09  COLLECTION  OF TAXES,  ASSESSMENTS  AND SIMILAR  ITEMS;
SERVICING ACCOUNTS.

          The Master  Servicer  shall  establish  and  maintain,  or cause to be
established  and maintained,  one or more accounts (the  "Servicing  Accounts"),
into  which all Escrow  Payments  shall be  deposited  and  retained.  Servicing
Accounts shall be Eligible  Accounts.  The Master  Servicer shall deposit in the
clearing  account in which it customarily  deposits  payments and collections on
mortgage loans in connection  with its mortgage loan  servicing  activities on a
daily  basis,  and in no event  more than one  Business  Day  after  the  Master
Servicer's  receipt  thereof,  all Escrow  Payments  collected on account of the
Mortgage  Loans  and  shall  thereafter  deposit  such  Escrow  Payments  in the
Servicing Accounts, in no event more than two Business Days after the receipt of
such Escrow Payments,  all Escrow Payments  collected on account of the Mortgage
Loans for the  purpose  of  effecting  the  timely  payment of any such items as
required  under the  terms of this  Agreement.  Withdrawals  of  amounts  from a
Servicing Account may be made only to (i) effect payment of taxes,  assessments,
hazard insurance  premiums,  and comparable items in a manner and at a time that
assures that the lien  priority of the  Mortgage is not  jeopardized  (or,  with
respect to the payment of taxes,  in a manner and at a time that avoids the loss
of the Mortgaged  Property due to a tax sale or the foreclosure as a result of a
tax lien);  (ii) reimburse the Master  Servicer (or a Sub-Servicer to the extent
provided in the related Sub-Servicing  Agreement) out of related collections for
any Servicing  Advances made pursuant to Section 3.01 (with respect to taxes and
assessments) and Section 3.14 (with respect to hazard  insurance);  (iii) refund
to Mortgagors  any sums as may be determined to be overages;  (iv) pay interest,
if required and as described  below,  to Mortgagors on balances in the Servicing
Account;  or (v) clear and terminate the Servicing Account at the termination of
the  Master  Servicer's  obligations  and  responsibilities  in  respect  of the
Mortgage  Loans under this  Agreement in  accordance  with Article X. The Master
Servicer will be responsible for the  administration  of the Servicing  Accounts
and will be obligated to make  Servicing  Advances to such  accounts when and as
necessary to avoid the lapse of insurance coverage on the Mortgaged Property, or
which the Master Servicer knows, or in the exercise of the required  standard of
care of the Master  Servicer  hereunder  should know,  is necessary to avoid the
loss of the Mortgaged  Property due to a tax sale or the foreclosure as a result
of a tax lien.  If any such  payment  has not been made and the Master  Servicer
receives  notice of a tax lien with respect to the Mortgage being  imposed,  the
Master Servicer will,  within 10 business days of such notice,  advance or cause
to be advanced funds necessary to discharge such lien on the Mortgaged Property.
As part of its servicing duties, the Master Servicer or Sub-Servicers  shall pay
to the  Mortgagors  interest on funds in the Servicing  Accounts,  to the extent
required  by law  and,  to the  extent  that  interest  earned  on  funds in the
Servicing  Accounts is insufficient,  to pay such interest from its or their own
funds, without any reimbursement therefor.

          Section 3.10 COLLECTION ACCOUNT AND DISTRIBUTION ACCOUNT.

          (a) On behalf of the Trust Fund, the Master  Servicer shall  establish
and maintain,  or cause to be established and  maintained,  one or more accounts
(such  account or accounts,  the  "Collection  Account"),  held in trust for the
benefit of the Trustee, the  Certificateholders  and the Certificate Insurer. On
behalf of the Trust  Fund,  the  Master  Servicer  shall  deposit or cause to be
deposited in the clearing account in which it customarily  deposits payments and
collections  on mortgage  loans in connection  with its mortgage loan  servicing
activities  on a daily  basis,  and in no event more than one Business Day after
the Master  Servicer's  receipt  thereof,  and shall  thereafter  deposit in the
Collection  Account,  in no event more than two  Business  Days after the Master
Servicer's  receipt  thereof,  as and when  received  or as  otherwise  required
hereunder,  the following payments and collections received or made by it (other
than in respect of principal or interest on the Mortgage  Loans due on or before
the Cut-off Date) or payments (other than Principal  Prepayments) received by it
on or prior to the Cut-off Date but allocable to a Due Period:

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

          (ii) all payments on account of interest (net of the related Servicing
     Fee) on each Mortgage Loan;

          (iii) all  Insurance  Proceeds and  Liquidation  Proceeds  (other than
     proceeds  collected in respect of any  particular  REO Property and amounts
     paid in  connection  with a purchase of Mortgage  Loans and REO  Properties
     pursuant to Section 10.01);

          (iv) any amounts required to be deposited  pursuant to Section 3.12 in
     connection with any losses realized on Permitted  Investments  with respect
     to funds held in the Collection Account;

          (v) any  amounts  required  to be  deposited  by the  Master  Servicer
     pursuant  to the  second  paragraph  of  Section  3.14(a) in respect of any
     blanket policy deductibles;

          (vi) all Prepayment Premiums;

          (vii) all proceeds of any Mortgage  Loan  repurchased  or purchased in
     accordance with Section 2.03 or Section 10.01; and

          (viii)  all  amounts  required  to be  deposited  in  connection  with
     Substitution Adjustments pursuant to Section 2.03.

          The foregoing requirements for deposit in the Collection Account shall
be  exclusive,  it being  understood  and  agreed  that,  without  limiting  the
generality  of the  foregoing,  payments in the nature of late payment  charges,
ancillary income and assumption fees, or insufficient  funds charges need not be
deposited by the Master  Servicer in the Collection  Account and may be retained
by the  Master  Servicer  as  additional  compensation.  In the event the Master
Servicer shall deposit in the  Collection  Account any amount not required to be
deposited  therein,  it may at any time withdraw such amount from the Collection
Account, any provision herein to the contrary notwithstanding.

          (b) On behalf of the Trust  Fund,  the  Trustee  shall  establish  and
maintain  one or more  accounts  (such  account or accounts,  the  "Distribution
Account"),  held in trust for the benefit of the Trustee, the Certificateholders
and the  Certificate  Insurer.  On behalf of the Trust Fund, the Master Servicer
shall deliver to the Trustee in immediately  available  funds for deposit in the
Distribution Account on or before the Close of Business New York time (i) on the
Master Servicer Remittance Date, that portion of the Available Funds (calculated
without regard to the  references in the definition  thereof to amounts that may
be withdrawn from the Distribution  Account) for the related  Distribution  Date
then on deposit in the Collection  Account,  and (ii) on each Business Day as of
the  commencement  of which the  balance on deposit  in the  Collection  Account
exceeds  $75,000  following  any  withdrawals  pursuant  to the next  succeeding
sentence,  the  amount  of  such  excess,  but  only if the  Collection  Account
constitutes an Eligible Account solely pursuant to clause (ii) of the definition
of  "Eligible  Account."  If the  balance on deposit in the  Collection  Account
exceeds  $75,000 as of the  commencement of business on any Business Day and the
Collection  Account  constitutes an Eligible  Account solely  pursuant to clause
(ii) of the definition of "Eligible  Account," the Master  Servicer shall, on or
before the Close of Business New York time on such Business  Day,  withdraw from
the Collection Account any and all amounts payable or reimbursable to the Master
Servicer,  the Trustee, the Seller or any Sub-Servicer  pursuant to Section 3.11
and shall pay such amounts to the Persons entitled thereto.

          (c) Funds in the Collection  Account and the Distribution  Account may
be invested in Permitted Investments in accordance with the provisions set forth
in Section 3.12.  The Master  Servicer  shall give notice to the Trustee and the
Certificate  Insurer of the location of the Collection  Account maintained by it
when established and prior to any change thereof.  The Trustee shall give notice
to the  Master  Servicer,  the  Depositor  and the  Certificate  Insurer  of the
location of the  Distribution  Account when  established and prior to any change
thereof.

          (d) Funds held in the Collection  Account at any time may be delivered
by the Master  Servicer to the  Trustee for deposit in an account  (which may be
the  Distribution  Account and must satisfy the standards  for the  Distribution
Account as set forth in the  definition  thereof)  and for all  purposes of this
Agreement  shall be deemed  to be a part of the  Collection  Account;  PROVIDED,
HOWEVER,  that the Trustee  shall have the sole  authority to withdraw any funds
held pursuant to this  subsection  (d). In the event the Master  Servicer  shall
deliver to the Trustee for  deposit in the  Distribution  Account any amount not
required to be  deposited  therein,  it may at any time request that the Trustee
withdraw  such  amount  from the  Distribution  Account and remit to it any such
amount, any provision herein to the contrary  notwithstanding.  In addition, the
Master Servicer,  with respect to items (i) through (v) below,  shall deliver to
the Trustee  from time to time for  deposit,  and the  Trustee,  with respect to
items (i) through (v) below, shall so deposit, in the Distribution Account:

          (i) any Advances, as required pursuant to Section 4.04;

          (ii) any amounts required to be deposited  pursuant to Section 3.23(d)
     or (f) in connection with any REO Property;

          (iii) any amounts to be paid in connection with a purchase of Mortgage
     Loans and REO Properties pursuant to Section 10.01;

          (iv) any  Compensating  Interest to be  deposited  pursuant to Section
     3.24 in connection with any Prepayment Interest Shortfall; and

          (v)any amounts paid by the PMI Insurer under the PMI Policy.

          (e) [Reserved].

          (f) The Master  Servicer shall deposit in the  Collection  Account any
amounts required to be deposited  pursuant to Section 3.12(b) in connection with
losses  realized  on  Permitted  Investments  with  respect to funds held in the
Collection Account.

          Section 3.11 WITHDRAWALS FROM THE COLLECTION  ACCOUNT AND DISTRIBUTION
ACCOUNT.

          (a) The Master  Servicer shall,  from time to time,  make  withdrawals
from the Collection Account for any of the following purposes or as described in
Section 4.04:

          (i) to remit to the Trustee for  deposit in the  Distribution  Account
     the  amounts  required to be so  remitted  pursuant  to Section  3.10(b) or
     permitted  to be so  remitted  pursuant  to the first  sentence  of Section
     3.10(d);

          (ii) subject to Section 3.16(d),  to reimburse the Master Servicer for
     Advances,  but only to the extent of amounts  received which represent Late
     Collections  (net of the  related  Servicing  Fees)  of  Monthly  Payments,
     Liquidation  Proceeds and Insurance Proceeds on Mortgage Loans with respect
     to which such  Advances  were made in  accordance  with the  provisions  of
     Section 4.03;

          (iii) subject to Section  3.16(d),  to pay the Master  Servicer or any
     Sub-Servicer (a) any unpaid Servicing Fees, (b) any unreimbursed  Servicing
     Advances with respect to each Mortgage  Loan, but only to the extent of any
     Late Collections, Liquidation Proceeds and Insurance Proceeds received with
     respect to such Mortgage Loan, and (c) any Servicing  Advances with respect
     to the  final  liquidation  of a  Mortgage  Loan  that  are  Nonrecoverable
     Advances,  but  only  to the  extent  that  Late  Collections,  Liquidation
     Proceeds and Insurance Proceeds received with respect to such Mortgage Loan
     are  insufficient to reimburse the Master Servicer or any  Sub-Servicer for
     Servicing Advances;

               (iv) to pay to the Master Servicer as servicing  compensation (in
      addition to the Servicing Fee) on the Master Servicer  Remittance Date any
      interest or investment  income earned on funds deposited in the Collection
      Account;

          (v) to pay to the Master Servicer or the Seller,  with respect to each
     Mortgage Loan that has previously  been  purchased or replaced  pursuant to
     Section 2.03 or Section 3.16(c) all amounts received thereon  subsequent to
     the date of purchase or substitution, as the case may be;

          (vi) to reimburse the Master Servicer for any Advance  previously made
     which the Master Servicer has determined to be a Nonrecoverable  Advance in
     accordance with the provisions of Section 4.04;

          (vii) to pay,  or to  reimburse  the  Master  Servicer  for  Servicing
     Advances in respect of,  expenses  incurred in connection with any Mortgage
     Loan pursuant to Section 3.16(b);

          (viii) to pay to the Master Servicer on a Servicer Remittance Date the
     excess  of  aggregate   Prepayment   Interest   Excesses  for  the  related
     Distribution Date over aggregate  Prepayment  Interest  Shortfalls for such
     Distribution Date; and

          (ix) to clear and terminate the Collection Account pursuant to Section
     10.01.

          The Master Servicer shall keep and maintain separate accounting,  on a
Mortgage  Loan by  Mortgage  Loan  basis,  for the  purpose  of  justifying  any
withdrawal  from the Collection  Account,  to the extent held by or on behalf of
it, pursuant to subclauses  (ii),  (iii),  (iv), (v), (vi) and (vii) above.  The
Master Servicer shall provide written  notification to the Trustee,  on or prior
to the next  succeeding  Servicer  Remittance  Date, upon making any withdrawals
from the Collection  Account pursuant to subclause (vi) above;  PROVIDED that an
Officer's  Certificate in the form described under Section 4.04(d) shall suffice
for such written notification to the Trustee in respect hereof.

          (b) The Trustee shall,  from time to time, make  withdrawals  from the
Distribution Account, for any of the following purposes, without priority:

          (i) to make distributions in accordance with Sections 4.01 and 8.05;

          (ii) to pay any  amounts  in  respect  of taxes  pursuant  to  Section
     9.01(g); and

          (iii) to clear and  terminate  the  Distribution  Account  pursuant to
     Section 10.01.

          Section 3.12  INVESTMENT  OF FUNDS IN THE  COLLECTION  ACCOUNT AND THE
     DISTRIBUTION ACCOUNT.

          (a)  The  Master  Servicer  may  direct  any  depository   institution
maintaining  the Collection  Account,  and the Trustee may direct any depository
institution  maintaining  the  Distribution  Account  (each  such  account,  for
purposes of this Section 3.12, an "Investment Account"),  to invest the funds in
such Investment Account in one or more Permitted Investments bearing interest or
sold at a discount,  and maturing,  unless payable on demand,  no later than the
Business Day immediately  preceding the date on which such funds are required to
be withdrawn from such account  pursuant to this  Agreement.  All such Permitted
Investments shall be held to maturity,  unless payable on demand. Any investment
of funds in an  Investment  Account shall be made in the name of the Trustee (in
its capacity as such),  or in the name of a nominee of the Trustee.  The Trustee
shall  be  entitled  to sole  possession  (except  with  respect  to  investment
direction  of funds  held in the  Collection  Account  and any  income  and gain
realized  thereon)  over  each such  investment,  and any  certificate  or other
instrument  evidencing any such  investment  shall be delivered  directly to the
Trustee or its agent,  together  with any  document  of  transfer  necessary  to
transfer  title to such  investment to the Trustee or its nominee.  In the event
amounts  on deposit  in an  Investment  Account  are at any time  invested  in a
Permitted Investment payable on demand, the Trustee shall:

          (x)  consistent  with any  notice  required  to be  given  thereunder,
               demand  that  payment  thereon  be  made  on the  last  day  such
               Permitted  Investment may otherwise mature hereunder in an amount
               equal to the lesser of (1) all amounts  then  payable  thereunder
               and (2) the amount required to be withdrawn on such date; and

          (y)  demand  payment  of all  amounts  due  thereunder  promptly  upon
               determination  by a Responsible  Officer of the Trustee that such
               Permitted  Investment would not constitute a Permitted Investment
               in respect  of funds  thereafter  on  deposit  in the  Investment
               Account.

          (b) All  income  and  gain  realized  from  the  investment  of  funds
deposited in the Collection  Account and any REO Account held by or on behalf of
the Master Servicer shall be for the benefit of the Master Servicer and shall be
subject to its  withdrawal in  accordance  with Section 3.11 or Section 3.23, as
applicable.  The Master Servicer shall deposit in the Collection  Account or any
REO Account,  as  applicable,  the amount of any loss of  principal  incurred in
respect  of any such  Permitted  Investment  made  with  funds in such  accounts
immediately upon realization of such loss.

          (c) All  income  and  gain  realized  from  the  investment  of  funds
deposited in the  Distribution  Account shall be for the benefit of the Trustee.
The Trustee shall deposit in the Distribution  Account the amount of any loss of
principal  incurred in respect of any such Permitted  Investment made with funds
in such accounts immediately upon realization of such loss.

          (d) Except as otherwise  expressly provided in this Agreement,  if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default  occurs  in any  other  performance  required  under any  Permitted
Investment, the Trustee may and, subject to Section 8.01 and Section 8.02(a)(v),
upon the  request  of the  Certificate  Insurer or the  Holders of  Certificates
representing  more  than 50% of the  Voting  Rights  allocated  to any  Class of
Certificates,  shall take such  action as may be  appropriate  to  enforce  such
payment or performance, including the institution and prosecution of appropriate
proceedings.

          Section 3.13 CLAIMS UPON THE PMI POLICY.

          The Master Servicer shall, on behalf of the Trust, prepare and file in
a  timely  basis  with  the  PMI  Insurer,  with a copy to the  Trustee  and the
Certificate  Insurer,  all claims  which may be made  under the PMI Policy  with
respect to PMI  Mortgage  Loans.  Consistent  with its  rights  and  obligations
hereunder,  the Master  Servicer  shall take all actions  required under the PMI
Policy as a condition to the payment of any such claim. Any amount received from
the PMI Insurer with respect to any such PMI Mortgage Loan shall be deposited by
the Master Servicer,  not later than the Business Day following receipt thereof,
into the Distribution  Account for distribution on the related Distribution Date
as part of Liquidation Proceeds for the related Loan Group.

          Section 3.14  MAINTENANCE OF HAZARD INSURANCE AND ERRORS AND OMISSIONS
AND FIDELITY COVERAGE.

          (a) The Master Servicer shall cause to be maintained for each Mortgage
Loan fire  insurance  with  extended  coverage on the  Mortgaged  Property in an
amount which is at least equal to the lesser of the current Principal Balance of
such Mortgage Loan and the amount  necessary to fully  compensate for any damage
or loss to the  improvements  that are a part of such  property on a replacement
cost basis,  in each case in an amount not less than such amount as is necessary
to avoid the  application  of any  coinsurance  clause  contained in the related
hazard insurance  policy.  The Master Servicer shall also cause to be maintained
fire insurance with extended coverage on each REO Property in an amount which is
at  least  equal  to the  lesser  of (i)  the  maximum  insurable  value  of the
improvements  which  are a part  of  such  property  and  (ii)  the  outstanding
Principal  Balance  of the  related  Mortgage  Loan at the time it became an REO
Property.  The Master  Servicer will comply in the performance of this Agreement
with all reasonable rules and requirements of each insurer under any such hazard
policies.  Any amounts to be  collected  by the Master  Servicer  under any such
policies  (other than amounts to be applied to the  restoration or repair of the
property  subject to the  related  Mortgage  or amounts  to be  released  to the
Mortgagor in  accordance  with the  procedures  that the Master  Servicer  would
follow in  servicing  loans held for its own  account,  subject to the terms and
conditions of the related  Mortgage and Mortgage Note) shall be deposited in the
Collection Account,  subject to withdrawal pursuant to Section 3.11, if received
in respect of a Mortgage  Loan,  or in the REO  Account,  subject to  withdrawal
pursuant to Section 3.23,  if received in respect of an REO  Property.  Any cost
incurred by the Master Servicer in maintaining any such insurance shall not, for
the  purpose  of  calculating   distributions  to  Certificateholders   and  the
Certificate  Insurer,  be added to the unpaid  Principal  Balance of the related
Mortgage Loan,  notwithstanding  that the terms of such Mortgage Loan so permit.
It is understood and agreed that no earthquake or other additional  insurance is
to be required of any Mortgagor  other than pursuant to such applicable laws and
regulations  as  shall  at any  time  be in  force  and as  shall  require  such
additional  insurance.  If the Mortgaged Property or REO Property is at any time
in an  area  identified  in  the  Federal  Register  by  the  Federal  Emergency
Management  Agency as having special flood hazards and flood  insurance has been
made  available,  the  Master  Servicer  will  cause  to be  maintained  a flood
insurance policy in respect thereof.  Such flood insurance shall be in an amount
equal to the lesser of (i) the unpaid Principal  Balance of the related Mortgage
Loan and (ii) the maximum  amount of such  insurance  available  for the related
Mortgaged Property under the national flood insurance program (assuming that the
area in which  such  Mortgaged  Property  is located  is  participating  in such
program).

          In the event  that the Master  Servicer  shall  obtain and  maintain a
blanket  policy with an insurer  having a General Policy Rating of A:X or better
in Best's Key Rating  Guide (or such other  rating  that is  comparable  to such
rating)  insuring  against hazard losses on all of the Mortgage  Loans, it shall
conclusively  be deemed to have  satisfied its  obligations  as set forth in the
first two sentences of this Section 3.14,  it being  understood  and agreed that
such policy may contain a deductible  clause,  in which case the Master Servicer
shall,  in the event that there  shall not have been  maintained  on the related
Mortgaged  Property  or REO  Property  a policy  complying  with the  first  two
sentences  of this  Section  3.14,  and there shall have been one or more losses
which would have been covered by such policy,  deposit to the Collection Account
from its own funds the amount not  otherwise  payable  under the blanket  policy
because  of such  deductible  clause.  In  connection  with  its  activities  as
administrator  and servicer of the Mortgage Loans, the Master Servicer agrees to
prepare and present,  on behalf of itself, the Trustee,  Certificateholders  and
the  Certificate  Insurer,  claims  under  any such  blanket  policy in a timely
fashion in accordance with the terms of such policy.

          (b) The Master  Servicer  shall keep in force  during the term of this
Agreement a policy or policies of insurance  covering  errors and  omissions for
failure in the  performance  of the  Master  Servicer's  obligations  under this
Agreement,  which policy or policies shall be in such form and amount that would
meet the  requirements  of Fannie Mae or Freddie Mac if it were the purchaser of
the  Mortgage  Loans,  unless the Master  Servicer has obtained a waiver of such
requirements  from Fannie Mae or Freddie  Mac.  The Master  Servicer  shall also
maintain a fidelity bond in the form and amount that would meet the requirements
of Fannie Mae or Freddie Mac,  unless the Master  Servicer has obtained a waiver
of such  requirements  from Fannie Mae or Freddie Mac. The Master Servicer shall
be deemed to have  complied  with this  provision  if an Affiliate of the Master
Servicer has such errors and  omissions  and fidelity  bond coverage and, by the
terms  of  such  insurance  policy  or  fidelity  bond,  the  coverage  afforded
thereunder extends to the Master Servicer.  Any such errors and omissions policy
and  fidelity  bond shall by its terms not be  cancelable  without  thirty days'
prior written notice to the Trustee.  The Master  Servicer shall also cause each
Sub-Servicer to maintain a policy of insurance covering errors and omissions and
a fidelity bond which would meet such requirements.

          Section  3.15   ENFORCEMENT   OF   DUE-ON-SALE   CLAUSES;   ASSUMPTION
AGREEMENTS.

          The  Master  Servicer  will,  to the  extent it has  knowledge  of any
conveyance or prospective  conveyance of any Mortgaged Property by any Mortgagor
(whether by absolute  conveyance or by contract of sale,  and whether or not the
Mortgagor  remains or is to remain  liable  under the  Mortgage  Note and/or the
Mortgage),  exercise its rights to accelerate the maturity of such Mortgage Loan
under the "due-on-sale" clause, if any, applicable thereto;  PROVIDED,  HOWEVER,
that the Master  Servicer  shall not be  required  to take such action if in its
sole  business  judgment  the  Master  Servicer  believes  it is not in the best
interests of the Trust Fund and shall not exercise any such rights if prohibited
by law from doing so. If the Master  Servicer  reasonably  believes it is unable
under  applicable  law to enforce such  "due-on-sale"  clause,  or if any of the
other  conditions set forth in the proviso to the preceding  sentence apply, the
Master Servicer will enter into an assumption and modification agreement from or
with the person to whom such  property  has been  conveyed  or is proposed to be
conveyed,  pursuant to which such person  becomes liable under the Mortgage Note
and, to the extent  permitted by  applicable  state law, the  Mortgagor  remains
liable  thereon.  The  Master  Servicer  is  also  authorized  to  enter  into a
substitution  of liability  agreement  with such  person,  pursuant to which the
original  Mortgagor is released from liability and such person is substituted as
the Mortgagor and becomes liable under the Mortgage Note,  provided that no such
substitution  shall be effective  unless such person  satisfies the underwriting
criteria of the Master  Servicer  and has a credit risk rating at least equal to
that  of  the  original   Mortgagor.   In  connection  with  any  assumption  or
substitution,  the Master Servicer shall apply such  underwriting  standards and
follow such practices and procedures as shall be normal and usual in its general
mortgage  servicing  activities  and as it applies to other mortgage loans owned
solely by it. The Master  Servicer  shall not take or enter into any  assumption
and modification  agreement,  however,  unless (to the extent practicable in the
circumstances) it shall have received confirmation, in writing, of the continued
effectiveness of any applicable hazard insurance policy or if such Mortgage Loan
is a PMI Mortgage Loan, the PMI Policy. Any fee collected by the Master Servicer
in respect of an assumption, modification or substitution of liability agreement
shall be retained by the Master Servicer as additional  servicing  compensation.
In connection  with any such  assumption,  no material term of the Mortgage Note
(including  but not limited to the related  Mortgage  Rate and the amount of the
Monthly  Payment)  may be  amended or  modified,  except as  otherwise  required
pursuant to the terms thereof. The Master Servicer shall notify the Trustee that
any such substitution,  modification or assumption  agreement has been completed
by  forwarding  to the  Trustee  the  executed  original  of such  substitution,
modification  or  assumption  agreement,  which  document  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.

          Notwithstanding the foregoing paragraph or any other provision of this
Agreement,  the Master Servicer shall not be deemed to be in default,  breach or
any other violation of its obligations  hereunder by reason of any assumption of
a Mortgage  Loan by operation of law or by the terms of the Mortgage Note or any
assumption  which the Master Servicer may be restricted by law from  preventing,
for  any  reason  whatever.   For  purposes  of  this  Section  3.15,  the  term
"assumption"  is  deemed  to also  include  a sale (of the  Mortgaged  Property)
subject to the Mortgage that is not accompanied by an assumption or substitution
of liability agreement.

          Section 3.16 REALIZATION UPON DEFAULTED MORTGAGE LOANS.

          (a) The Master  Servicer shall use its best efforts,  consistent  with
Servicing  Standard,  to  foreclose  upon or  otherwise  comparably  convert the
ownership of properties  securing such of the Mortgage Loans (including  selling
any such  Mortgage  Loans other than  converting  the  ownership  of the related
properties) as come into and continue in default and as to which no satisfactory
arrangements  can be made for  collection  of  delinquent  payments  pursuant to
Section  3.07.  The  Master  Servicer  shall be  responsible  for all  costs and
expenses incurred by it in any such proceedings;  PROVIDED,  HOWEVER,  that such
costs and  expenses  will be  recoverable  as  Servicing  Advances by the Master
Servicer as  contemplated  in Section 3.11 and Section  3.23.  The  foregoing is
subject to the provision  that, in any case in which  Mortgaged  Property  shall
have suffered damage from an Uninsured  Cause,  the Master Servicer shall not be
required to expend its own funds toward the  restoration of such property unless
it shall  determine in its discretion  that such  restoration  will increase the
proceeds of  liquidation  of the related  Mortgage Loan after  reimbursement  to
itself for such expenses.

          (b) Notwithstanding  the foregoing  provisions of this Section 3.16 or
any other provision of this  Agreement,  with respect to any Mortgage Loan as to
which the Master Servicer has received actual notice of, or has actual knowledge
of, the  presence of any toxic or hazardous  substance on the related  Mortgaged
Property,  the Master  Servicer shall not, on behalf of the Trustee,  either (i)
obtain title to such Mortgaged Property as a result of or in lieu of foreclosure
or otherwise,  or (ii) otherwise acquire possession of, or take any other action
with respect to, such  Mortgaged  Property,  if, as a result of any such action,
the Trustee, the Trust Fund, the  Certificateholders  or the Certificate Insurer
would be considered to hold title to, to be a  "mortgagee-in-possession"  of, or
to be an "owner" or "operator" of such Mortgaged  Property within the meaning of
the  Comprehensive  Environmental  Response,  Compensation  and Liability Act of
1980, as amended from time to time,  or any  comparable  law,  unless the Master
Servicer has also previously determined,  based on its reasonable judgment and a
report prepared by a Person who regularly  conducts  environmental  audits using
customary industry standards, that:

          (i)  such  Mortgaged   Property  is  in  compliance   with  applicable
     environmental  laws or,  if not,  that it  would  be in the  best  economic
     interest of the Trust Fund to take such  actions as are  necessary to bring
     the Mortgaged Property into compliance therewith; and

          (ii) there are no  circumstances  present at such  Mortgaged  Property
     relating to the use,  management or disposal of any  hazardous  substances,
     hazardous  materials,  hazardous wastes, or  petroleum-based  materials for
     which  investigation,   testing,  monitoring,   containment,   clean-up  or
     remediation  could be  required  under any  federal,  state or local law or
     regulation, or that if any such materials are present for which such action
     could be required,  that it would be in the best  economic  interest of the
     Trust Fund to take such  actions  with  respect to the  affected  Mortgaged
     Property.

          The  cost  of the  environmental  audit  report  contemplated  by this
Section  3.16 shall be  advanced by the Master  Servicer,  subject to the Master
Servicer's  right to be  reimbursed  therefor  from the  Collection  Account  as
provided in Section 3.11(a)(vii), such right of reimbursement being prior to the
rights of  Certificateholders  to receive any amount in the  Collection  Account
received in respect of the affected Mortgage Loan or other Mortgage Loans.

          If the Master Servicer  determines,  as described above, that it is in
the best  economic  interest  of the  Trust  Fund to take  such  actions  as are
necessary to bring any such Mortgaged  Property into  compliance with applicable
environmental  laws,  or to take such  action with  respect to the  containment,
clean-up or remediation of hazardous substances,  hazardous materials, hazardous
wastes or petroleum-based  materials affecting any such Mortgaged Property, then
the  Master  Servicer  shall  take  such  action  as it  deems to be in the best
economic interest of the Trust Fund;  PROVIDED that any amounts disbursed by the
Master  Servicer  pursuant to this Section  3.16(b) shall  constitute  Servicing
Advances,  subject  to  Section  4.04(d).  The  cost  of  any  such  compliance,
containment,  cleanup or remediation  shall be advanced by the Master  Servicer,
subject  to the  Master  Servicer's  right to be  reimbursed  therefor  from the
Collection Account as provided in Section 3.11(a)(iii) and (a)(vii),  such right
of reimbursement being prior to the rights of  Certificateholders to receive any
amount in the Collection  Account  received in respect of the affected  Mortgage
Loan or other Mortgage Loans.

          (c)  The  Master  Servicer  or the  Special  Servicer,  if the  Master
Servicer  elects not to exercise  such option,  may at its option  purchase from
each Loan Group,  any Mortgage  Loan or related REO Property  that is 90 days or
more  delinquent,  which  the  Master  Servicer  or  the  Special  Servicer,  as
applicable,   determines  in  good  faith  will  otherwise   become  subject  to
foreclosure  proceedings  (evidence  of such  determination  to be  delivered in
writing to the Trustee and the  Certificate  Insurer  prior to  purchase),  at a
price  equal to the  Purchase  Price;  PROVIDED,  HOWEVER,  that (i) the  Master
Servicer  or the  Special  Servicer,  as  applicable,  shall  purchase  any such
Mortgage Loans or related REO Properties on the basis of delinquency, purchasing
the most  delinquent  Mortgage  Loans or related REO  Properties  first and (ii)
after such parties (or the entities  contemplated  in Section 3.25 below) in the
aggregate  shall have  purchased  3.00% of the  Mortgage  Loans or  related  REO
Properties  in each Loan Group,  by Cut-off Date  Aggregate  Principal  Balance,
pursuant to clause (i) above or Section 3.25 below,  the Master  Servicer or the
Special Servicer, as applicable, must also obtain the consent of the Certificate
Insurer prior to any further purchases, provided that failure of the Certificate
Insurer to respond  within five Business Days  following  actual  receipt of any
such  request for consent by the Master  Servicer  or the Special  Servicer,  as
applicable,  shall be deemed to constitute  consent to the additional  purchases
identified in such request for consent. The Purchase Price for any Mortgage Loan
or  related  REO  Property  purchased   hereunder  shall  be  deposited  in  the
Distribution  Account,  and the  Trustee,  upon receipt of such  deposit,  shall
release or cause to be released to the Master Servicer or the Special  Servicer,
as  applicable,  the related  Mortgage  File and shall  execute and deliver such
instruments of transfer or  assignment,  in each case without  recourse,  as the
Master  Servicer or the Special  Servicer,  as applicable,  shall furnish and as
shall be  necessary  to vest in it title to any  Mortgage  Loan or  related  REO
Property released pursuant hereto.

          (d)  Proceeds   received  in  connection   with  any  Final   Recovery
Determination,  as well as any recovery  resulting from a partial  collection of
Insurance  Proceeds or  Liquidation  Proceeds,  in respect of any Mortgage Loan,
will be applied in the  following  order of priority:  FIRST,  to reimburse  the
Master  Servicer  or any  Sub-Servicer  for any related  unreimbursed  Servicing
Advances and Advances,  pursuant to Section 3.11(a)(ii) or (a)(iii);  SECOND, to
accrued  and unpaid  interest  on the  Mortgage  Loan,  to the date of the Final
Recovery  Determination,  or to the Due Date prior to the  Distribution  Date on
which such  amounts  are to be  distributed  if not in  connection  with a Final
Recovery  Determination;  and THIRD,  as a recovery of principal of the Mortgage
Loan.  If the amount of the  recovery so  allocated to interest is less than the
full amount of accrued and unpaid interest due on such Mortgage Loan, the amount
of such recovery will be allocated by the Master Servicer as follows:  FIRST, to
unpaid  Servicing Fees; and SECOND,  to the balance of the interest then due and
owing.  The portion of the recovery so allocated to unpaid  Servicing Fees shall
be reimbursed  to the Master  Servicer or any  Sub-Servicer  pursuant to Section
3.11(a)(iii).

          Section 3.17 TRUSTEE TO COOPERATE; RELEASE OF MORTGAGE FILES.

          (a) Upon the payment in full of any Mortgage  Loan,  or the receipt by
the Master Servicer of a notification  that payment in full shall be escrowed in
a manner  customary for such purposes,  the Master Servicer shall deliver to the
Trustee two executed copies of a completed  certification  (which  certification
shall  include a  statement  to the effect  that all  amounts  received or to be
received in  connection  with such payment which are required to be deposited in
the  Collection  Account  pursuant  to  Section  3.10  have  been  or will be so
deposited)  of a  Servicing  Officer  and shall  request  delivery  to it of the
Mortgage  File.  Upon receipt of such  certification  and  request,  the Trustee
shall,  within five Business  Days,  release and send by overnight  mail, at the
expense  of the  Master  Servicer,  the  related  Mortgage  File  to the  Master
Servicer.  The Trustee agrees to indemnify the Master  Servicer,  out of its own
funds,  for any loss,  liability  or  expense  (other  than  special,  indirect,
punitive  or  consequential  damages  which  will  not be paid  by the  Trustee)
incurred by the Master Servicer as a proximate result of the Trustee's breach of
its  obligations  pursuant  to  this  Section  3.17.  No  expenses  incurred  in
connection with any instrument of satisfaction or deed of reconveyance  shall be
chargeable to the Collection  Account or the Distribution  Account.  The Trustee
will provide to the Certificate Insurer an updated listing of any Mortgage Files
released pursuant to this Section 3.17(a) on March 30, June 30, September 30 and
December 30 of each year,  beginning in December 1999 and as otherwise requested
by the Certificate Insurer or the Trustee.

          (b)  From  time to  time  and as  appropriate  for  the  servicing  or
foreclosure of any Mortgage Loan, including, for this purpose,  collection under
any insurance policy relating to the Mortgage Loans, the Trustee shall, upon any
request made by or on behalf of the Master  Servicer and delivery to the Trustee
of a Request for Release in the form of Exhibit F, release the related  Mortgage
File to the Master  Servicer,  and the Trustee  shall,  at the  direction of the
Master Servicer, execute such documents as shall be necessary to the prosecution
of any such  proceedings.  Such  Request for Release  shall  obligate the Master
Servicer  to  return  each and  every  document  previously  requested  from the
Mortgage  File to the Trustee when the need  therefor by the Master  Servicer no
longer exists,  unless the Mortgage Loan has been liquidated and the Liquidation
Proceeds  relating to the Mortgage  Loan have been  deposited in the  Collection
Account or the Mortgage File or such document has been delivered to an attorney,
or to a public trustee or other public official as required by law, for purposes
of initiating or pursuing legal action or other  proceedings for the foreclosure
of the Mortgaged  Property either judicially or  non-judicially,  and the Master
Servicer has delivered,  or caused to be delivered, to the Trustee an additional
Request for Release  certifying as to such liquidation or action or proceedings.
Upon the request of the Trustee or the Certificate  Insurer, the Master Servicer
shall provide notice to the Trustee and the Certificate  Insurer of the name and
address of the Person to which such Mortgage File or such document was delivered
and the purpose or purposes of such delivery. Upon receipt of a certificate of a
Servicing  Officer  stating that such Mortgage Loan was  liquidated and that all
amounts  received or to be received in connection with such liquidation that are
required to be deposited into the Collection Account have been so deposited,  or
that such Mortgage Loan has become an REO Property, any outstanding Requests for
Release with respect to such  Mortgage  Loan shall be released by the Trustee to
the Master Servicer or its designee.

          (c) Upon written  certification  of a Servicing  Officer,  the Trustee
shall  execute and deliver to the Master  Servicer or the  Sub-Servicer,  as the
case  may be,  and upon the  request  of the  Certificate  Insurer,  the  Master
Servicer  shall  deliver or cause to be  delivered  to the  Certificate  Insurer
copies of, any court  pleadings,  requests for trustee's sale or other documents
necessary  to the  foreclosure  or  trustee's  sale in  respect  of a  Mortgaged
Property or to any legal action brought to obtain judgment against any Mortgagor
on the  Mortgage  Note or Mortgage  or to obtain a  deficiency  judgment,  or to
enforce any other  remedies or rights  provided by the Mortgage Note or Mortgage
or  otherwise  available  at law or in  equity.  Each such  certification  shall
include a request  that such  pleadings  or documents be executed by the Trustee
and a statement as to the reason such  documents  or pleadings  are required and
that the  execution and delivery  thereof by the Trustee will not  invalidate or
otherwise affect the lien of the Mortgage,  except for the termination of such a
lien upon completion of the foreclosure or trustee's sale.

          Section 3.18 SERVICING COMPENSATION.

          As compensation  for the activities of the Master Servicer  hereunder,
the Master  Servicer shall be entitled to the Servicing Fee with respect to each
Mortgage Loan,  other than a Specially  Serviced  Mortgage Loan,  payable solely
from payments of interest in respect of such Mortgage  Loan,  subject to Section
3.24.  In  addition,  the Master  Servicer  shall be entitled to recover  unpaid
Servicing Fees out of Insurance  Proceeds or Liquidation  Proceeds to the extent
permitted by Section  3.11(a)(iii) and out of amounts derived from the operation
and sale of an REO Property to the extent  permitted by Section 3.23.  The right
to receive the Servicing Fee may not be  transferred  in whole or in part except
in connection with the transfer of all of the Master Servicer's responsibilities
and  obligations  under  this  Agreement;  PROVIDED,  HOWEVER,  that the  Master
Servicer  may pay from  the  Servicing  Fee any  amounts  due to a  Sub-Servicer
pursuant to a Sub-Servicing Agreement entered into under Section 3.02.

          Additional  servicing  compensation  in the form of  assumption  fees,
ancillary  income  and late  payment  charges,  insufficient  funds  charges  or
otherwise (subject to Section 3.24 and other than Prepayment  Premiums) shall be
retained  by the Master  Servicer  only to the extent  such fees or charges  are
received  by the Master  Servicer.  The Master  Servicer  shall also be entitled
pursuant to Section  3.11(a)(iv)  to withdraw  from the  Collection  Account and
pursuant to Section  3.23(b) to withdraw  from any REO  Account,  as  additional
servicing  compensation,  interest or other income  earned on deposits  therein,
subject to Section 3.12 and Section 3.24. The Master  Servicer shall be required
to pay all expenses  incurred by it in connection with its servicing  activities
hereunder (including premiums for the insurance required by Section 3.14, to the
extent such premiums are not paid by the related Mortgagors or by a Sub-Servicer
and servicing  compensation of each  Sub-Servicer)  and shall not be entitled to
reimbursement therefor except as specifically provided herein.

          Section 3.19 REPORTS TO THE TRUSTEE; COLLECTION ACCOUNT STATEMENTS.

          Not later than twenty days after each  Distribution  Date,  the Master
Servicer shall forward,  upon request,  to the Trustee,  the Certificate Insurer
and the Depositor the most current  available  bank statement for the Collection
Account.  Copies of such  statement  shall be  provided  by the  Trustee  to any
Certificateholder  and to any Person  identified to the Trustee as a prospective
transferee  of a  Certificate,  upon  request at the  expense of the  requesting
party,  provided  such  statement  is  delivered  by the Master  Servicer to the
Trustee.

          Section 3.20 STATEMENT AS TO COMPLIANCE.

          The Master Servicer and the Special Servicer each shall deliver to the
Trustee,  the  Certificate  Insurer  and the  Depositor  not later  than 90 days
following  the end of the fiscal year of the Master  Servicer and of the Special
Servicer,  commencing  with the fiscal  year that begins in 1999,  an  Officers'
Certificate  stating,  as to each  signatory  thereof,  that (i) a review of the
activities of the Master Servicer or Special Servicer, as applicable, during the
preceding year and of performance  under this Agreement has been made under such
officers' supervision and (ii) to the best of such officers' knowledge, based on
such review,  the Master Servicer or the Special  Servicer,  as applicable,  has
fulfilled all of its obligations under this Agreement  throughout such year, or,
if  there  has  been a  default  in the  fulfillment  of  any  such  obligation,
specifying  each such  default  known to such  officer and the nature and status
thereof.  Copies of any such  statement  shall be provided by the Trustee to any
Certificateholder  and to any Person  identified to the Trustee as a prospective
transferee  of a  Certificate,  upon  request at the  expense of the  requesting
party,  provided  such  statement  is  delivered  by the Master  Servicer or the
Special Servicer, as applicable, to the Trustee.

          Section 3.21 INDEPENDENT PUBLIC ACCOUNTANTS' SERVICING REPORT.

          Not later than 90 days  following  the end of each  fiscal year of the
Master Servicer and the Special  Servicer,  commencing with the fiscal year that
begins in 1999, the Master  Servicer and the Special  Servicer,  each at its own
expense,  shall cause a  nationally  recognized  firm of  independent  certified
public accountants to furnish to the Master Servicer or the Special Servicer, as
applicable, a report stating that (i) it has obtained a letter of representation
regarding  certain  matters from the  management  of the Master  Servicer or the
Special  Servicer,  as  applicable,  which includes an assertion that the Master
Servicer or the Special  Servicer,  as  applicable,  has  complied  with certain
minimum residential mortgage loan servicing standards, identified in the Uniform
Single  Attestation  Program for Mortgage  Bankers  established  by the Mortgage
Bankers  Association  of America,  with respect to the servicing of  residential
mortgage  loans during the most recently  completed  fiscal year and (ii) on the
basis of an  examination  conducted by such firm in  accordance  with  standards
established  by the American  Institute of Certified  Public  Accountants,  such
representation  is  fairly  stated in all  material  respects,  subject  to such
exceptions and other  qualifications  that may be appropriate.  In rendering its
report such firm may rely,  as to matters  relating to the direct  servicing  of
residential mortgage loans by Sub-Servicers, upon comparable reports of firms of
independent  certified public accountants  rendered on the basis of examinations
conducted in accordance  with the same  standards  (rendered  within one year of
such report) with respect to those  Sub-Servicers.  Immediately  upon receipt of
such report, the Master Servicer or the Special Servicer,  as applicable,  shall
furnish a copy of such report to the Trustee,  the Certificate  Insurer and each
Rating Agency.  Copies of such statement shall be provided by the Trustee to any
Certificateholder  upon  request at the  expense of the Master  Servicer  or the
Special  Servicer,  as applicable,  provided that such statement is delivered by
the Master Servicer or the Special Servicer, as applicable, to the Trustee.

          Section  3.22  ACCESS TO CERTAIN  DOCUMENTATION;  FILING OF REPORTS BY
TRUSTEE.

          (a)  The  Master  Servicer  shall  provide  to the  Office  of  Thrift
Supervision,  the FDIC,  and any other  federal or state  banking  or  insurance
regulatory  authority that may exercise  authority  over any  Certificateholder,
access to the documentation  regarding the Mortgage Loans required by applicable
laws and  regulations.  Such access shall be afforded  without charge,  but only
upon  reasonable  request and during normal business hours at the offices of the
Master  Servicer  designated  by it. In  addition,  access to the  documentation
regarding  the  Mortgage  Loans will be provided to any  Certificateholder,  the
Certificate  Insurer,  the  Trustee and to any Person  identified  to the Master
Servicer as a prospective  transferee of a Certificate,  upon reasonable request
during normal business hours at the offices of the Master Servicer designated by
it at the expense of the Person requesting such access.

          (b) The Trustee shall, on behalf of the Trust Fund, prepare,  sign and
file with the Securities and Exchange Commission any and all reports, statements
and information respecting the Trust which the Depositor determines are required
to be filed with the  Securities  and Exchange  Commission  pursuant to Sections
13(a) or 15(d) of the  Securities  Exchange Act of 1934,  as amended,  each such
report, statement and information to be filed on or prior to the required filing
date for such report, statement or information. Upon the request of the Trustee,
each of the Seller,  the Master  Servicer and the Depositor shall cooperate with
the  Trustee in the  preparation  of any such  report  and shall  provide to the
Trustee in a timely manner all such  information or documentation as the Trustee
may  reasonably  request in connection  with the  performance  of its duties and
obligations under this Section.

          Section 3.23 TITLE, MANAGEMENT AND DISPOSITION OF REO PROPERTY.

          (a) The deed or certificate of sale of any REO Property shall be taken
in the name of the  Trustee,  or its  nominee,  in trust for the  benefit of the
Certificateholders  and the Certificate Insurer. The Master Servicer,  on behalf
of REMIC I,  shall  either  sell any REO  Property  by the end of the third full
taxable  year after the taxable  year in which the REMIC  acquires  ownership of
such REO Property for purposes of Section 860G(a)(8) of the Code or request from
the Internal Revenue Service,  no later than 60 days before the day on which the
grace period would  otherwise  expire,  an extension of such period,  unless the
Master  Servicer  shall have  delivered  to the  Trustee an Opinion of  Counsel,
addressed to the Trustee,  the  Certificate  Insurer and the  Depositor,  to the
effect that the holding by REMIC I of such REO Property  subsequent to the close
of the  third  taxable  year  after  its  acquisition  will  not  result  in the
imposition  on any  REMIC of  taxes on  "prohibited  transactions"  thereof,  as
defined in Section 860F of the Code,  or cause any REMIC to fail to qualify as a
REMIC under Federal law at any time that any Certificates  are outstanding.  The
Master  Servicer shall manage,  conserve,  protect and operate each REO Property
for the Certificateholders  solely for the purpose of its prompt disposition and
sale in a manner  which does not cause such REO  Property  to fail to qualify as
"foreclosure  property" within the meaning of Section  860G(a)(8) of the Code or
result in the receipt by any REMIC of any  "income  from  non-permitted  assets"
within the meaning of Section 860F(a)(2)(B) of the Code, or any "net income from
foreclosure property" which is subject to taxation under the REMIC Provisions.

          (b) The  Master  Servicer  shall  separately  account  for  all  funds
collected and received in connection  with the operation of any REO Property and
shall establish and maintain,  or cause to be established  and maintained,  with
respect to REO  Properties  an  account  held in trust for the  Trustee  for the
benefit  of  the  Certificateholders  and  the  Certificate  Insurer  (the  "REO
Account"),  which shall be an Eligible  Account.  The Master  Servicer  shall be
permitted to allow the Collection  Account to serve as the REO Account,  subject
to separate ledgers for each REO Property. The Master Servicer shall be entitled
to retain or withdraw  any  interest  income paid on funds  deposited in the REO
Account.

          (c) The Master  Servicer shall have full power and authority,  subject
only to the specific requirements and prohibitions of this Agreement,  to do any
and all things in connection  with any REO Property as are  consistent  with the
manner in which the Master Servicer  manages and operates similar property owned
by the Master Servicer or any of its Affiliates,  all on such terms and for such
period  as  the  Master   Servicer   deems  to  be  in  the  best  interests  of
Certificateholders.  In connection therewith, the Master Servicer shall deposit,
or  cause to be  deposited  in the  clearing  account  in  which it  customarily
deposits  payments and  collections  on mortgage  loans in  connection  with its
mortgage loan servicing  activities on a daily basis,  and in no event more than
one  Business  Day  after  the  Master  Servicer's  receipt  thereof,  and shall
thereafter  deposit in the REO Account,  in no event more than two Business Days
after the Master  Servicer's  receipt thereof,  all revenues received by it with
respect to an REO Property and shall withdraw  therefrom funds necessary for the
proper  operation,  management and  maintenance of such REO Property  including,
without limitation:

          (i) all  insurance  premiums  due and  payable  in respect of such REO
     Property;

          (ii) all real  estate  taxes and  assessments  in  respect of such REO
     Property that may result in the imposition of a lien thereon; and

          (iii) all costs and expenses necessary to maintain such REO Property.

To the extent that  amounts on deposit in the REO Account with respect to an REO
Property  are  insufficient  for the  purposes  set forth in clauses (i) through
(iii) above with respect to such REO Property, the Master Servicer shall advance
from its own funds such amount as is  necessary  for such  purposes if, but only
if, the Master  Servicer  would make such advances if the Master  Servicer owned
the REO Property and if in the Master Servicer's  judgment,  the payment of such
amounts will be recoverable from the rental or sale of the REO Property.

          Notwithstanding  the  foregoing,  neither the Master  Servicer nor the
Trustee shall:

          (i)  authorize  the Trust Fund to enter into,  renew or extend any New
     Lease with respect to any REO Property,  if the New Lease by its terms will
     give rise to any income that does not constitute Rents from Real Property;

          (ii)  authorize  any amount to be  received  or accrued  under any New
     Lease other than amounts that will constitute Rents from Real Property;

          (iii) authorize any  construction on any REO Property,  other than the
     completion  of a building or other  improvement  thereon,  and then only if
     more  than  ten  percent  of the  construction  of such  building  or other
     improvement  was  completed  before  default on the related  Mortgage  Loan
     became  imminent,  all within the  meaning of Section  856(e)(4)(B)  of the
     Code; or

          (iv) authorize any Person to Directly  Operate any REO Property on any
     date more than 90 days after its date of acquisition by the Trust Fund;

unless,  in any such  case,  the  Master  Servicer  has  obtained  an Opinion of
Counsel, provided to the Trustee and the Certificate Insurer, to the effect that
such action will not cause such REO Property to fail to qualify as  "foreclosure
property" within the meaning of Section  860G(a)(8) of the Code at any time that
it is held by REMIC I, in which case the Master  Servicer  may take such actions
as are specified in such Opinion of Counsel.

          The Master Servicer may contract with any  Independent  Contractor for
the operation and management of any REO Property, provided that:

          (i) the  terms  and  conditions  of any  such  contract  shall  not be
     inconsistent herewith;

          (ii) any such contract  shall  require,  or shall be  administered  to
     require,  that  the  Independent  Contractor  pay all  costs  and  expenses
     incurred  in  connection  with the  operation  and  management  of such REO
     Property,  including those listed above and remit all related revenues (net
     of such costs and expenses) to the Master  Servicer as soon as practicable,
     but in no event  later than thirty days  following  the receipt  thereof by
     such Independent Contractor;

          (iii) none of the provisions of this Section  3.23(c)  relating to any
     such contract or to actions taken through any such  Independent  Contractor
     shall be deemed to  relieve  the Master  Servicer  of any of its duties and
     obligations  to the  Trustee  on behalf of the  Certificateholders  and the
     Certificate  Insurer with respect to the  operation  and  management of any
     such REO Property; and

          (iv) the Master  Servicer shall be obligated  with respect  thereto to
     the same extent as if it alone were  performing all duties and  obligations
     in connection with the operation and management of such REO Property.

The Master  Servicer  shall be  entitled  to enter into any  agreement  with any
Independent  Contractor  performing  services  for it  related to its duties and
obligations  hereunder  for  indemnification  of the  Master  Servicer  by  such
Independent  Contractor,  and nothing in this Agreement shall be deemed to limit
or modify such  indemnification.  The Master Servicer shall be solely liable for
all fees owed by it to any such Independent Contractor,  irrespective of whether
the Master Servicer's compensation pursuant to Section 3.18 is sufficient to pay
such fees; PROVIDED,  HOWEVER, that to the extent that any payments made by such
Independent Contractor would constitute Servicing Advances if made by the Master
Servicer,  such amounts shall be reimbursable as Servicing  Advances made by the
Master Servicer.

          (d) In addition to the withdrawals  permitted  under Section  3.23(c),
the Master Servicer may from time to time make  withdrawals from the REO Account
for any REO Property:  (i) to pay itself or any  Sub-Servicer  unpaid  Servicing
Fees in respect of the related  Mortgage Loan;  and (ii) to reimburse  itself or
any  Sub-Servicer  for  unreimbursed  Servicing  Advances and  Advances  made in
respect  of such REO  Property  or the  related  Mortgage  Loan.  On the  Master
Servicer  Remittance  Date,  the Master  Servicer  shall  withdraw from each REO
Account maintained by it and deposit into the Distribution Account in accordance
with Section  3.10(d)(ii),  for distribution on the related Distribution Date in
accordance with Section 4.01, the income from the related REO Property  received
during the prior calendar month, net of any withdrawals made pursuant to Section
3.23(c) or this Section 3.23(d).

          (e) Subject to the time constraints set forth in Section 3.23(a), each
REO  Disposition  shall be carried out by the Master  Servicer at such price and
upon such terms and  conditions as the Master  Servicer  shall deem necessary or
advisable, as shall be normal and usual in its Servicing Standard.

          (f) The proceeds from the REO Disposition,  net of any amount required
by law to be remitted to the Mortgagor  under the related  Mortgage Loan and net
of any payment or  reimbursement  to the Master Servicer or any  Sub-Servicer as
provided  above,  shall be deposited in the  Distribution  Account in accordance
with Section  3.10(d)(ii) on the Master  Servicer  Remittance  Date in the month
following the receipt thereof for distribution on the related  Distribution Date
in accordance  with Section  4.01.  Any REO  Disposition  shall be for cash only
(unless changes in the REMIC Provisions made subsequent to the Startup Day allow
a sale for other consideration).

          (g) The Master Servicer shall file information returns with respect to
the receipt of mortgage  interest  received in a trade or  business,  reports of
foreclosures  and  abandonments  of any Mortgaged  Property and  cancellation of
indebtedness  income  with  respect to any  Mortgaged  Property  as  required by
Sections 6050H, 6050J and 6050P of the Code, respectively. Such reports shall be
in form and substance  sufficient to meet the reporting  requirements imposed by
such Sections 6050H, 6050J and 6050P of the Code.

          Section  3.24  OBLIGATIONS  OF  THE  MASTER  SERVICER  IN  RESPECT  OF
PREPAYMENT INTEREST SHORTFALLS.

          Not  later  than  the  Close  of  Business  on  each  Master  Servicer
Remittance  Date, the Master  Servicer shall remit to the Collection  Account an
amount ("Compensating Interest") equal to the lesser of (A) (1) the aggregate of
the Prepayment Interest  Shortfalls for the related  Distribution Date minus (2)
the aggregate of the Prepayment  Interest Excesses for the related  Distribution
Date and (B) its  Servicing  Fee received in the related Due Period.  The Master
Servicer shall not have the right to  reimbursement  for any amounts remitted to
the Trustee in respect of Compensating Interest.  Such amounts so remitted shall
be included in the Available Funds relating to the Loan Group  experiencing  the
Principal  Prepayments and distributed  therewith on the next Distribution Date.
If on any  Master  Servicer  Remittance  Date  the  amount  deposited  into  the
Collection  Account  is the  amount  calculated  in (B),  such  amount  shall be
allocated  between the Available  Funds of each Loan Group pro rata based on the
aggregate  Prepayment Interest Shortfall  experienced by both Loan Groups during
the  related Due  Period.  The Master  Servicer  shall not be  obligated  to pay
Compensating Interest with respect to Relief Act Interest Shortfalls.

          Section 3.25 CERTAIN  RIGHTS  RELATED TO  FORECLOSURE  AND THE SPECIAL
SERVICER.

          (a) The  Directing  Holder shall have the right to purchase  defaulted
Mortgage Loans from the Trust Fund as and to the extent provided herein.  At any
time,  the  Directing  Holder  may  request  that the  Special  Servicer  take a
particular  action  permitted  under this Agreement with respect to a particular
Specially  Serviced  Mortgage Loan,  including without  limitation  foreclosure,
waivers or modifications.  Any such request shall be in writing, a copy of which
shall be delivered to the Master  Servicer.  Within two Business Days of receipt
of such a request,  the  Special  Servicer  shall  notify the  Directing  Holder
whether the Special Servicer intends to comply with such request. If the Special
Servicer  does not comply with such  request  (or fails to notify the  Directing
Holder of its decision  within the two Business Day period),  then the Directing
Holder may, at its sole option and upon written  notice to the Special  Servicer
and the Master Servicer,  purchase the related Mortgage Loan from the Trust Fund
at the  Purchase  Price.  In  addition,  the  Directing  Holder may purchase any
Severely  Delinquent  Loan upon  written  notice to the Master  Servicer and the
Special  Servicer  within  three  days of the day on which  such  Mortgage  Loan
becomes  a  Severely  Delinquent  Loan.  After  Mortgage  Loans or  related  REO
Properties in a Loan Group have been purchased, together with Mortgage Loans and
related REO Properties  purchased pursuant (i) to the two immediately  preceding
sentences,  (ii) to  subsection  (b) below and (iii) to Section  3.16(c),  in an
amount equal to 3.00% by Cut-off Date Aggregate Principal Balance, the Directing
Holder must obtain the consent of the  Certificate  Insurer prior to any further
purchases  of Mortgage  Loans in such Loan Group,  provided  that failure of the
Certificate  Insurer to respond  within  five  Business  Days  following  actual
receipt of any such request for consent by the Directing  Holder shall be deemed
to constitute consent to the additional purchases identified in such request for
consent.

          (b) In addition to the purchase option  provided under  subsection (a)
above,  the Special  Servicer and the  Directing  Holder shall have the right to
purchase Severely  Delinquent Loans from the Trust Fund as set forth herein. The
Special  Servicer shall have the right to purchase any Severely  Delinquent Loan
at the Purchase Price (as defined in this Agreement). The Special Servicer shall
send a written notice (the "Initial  Notice") to the Directing  Holder  advising
the Directing  Holder that the Special  Servicer  intends to purchase a Severely
Delinquent  Loan.  The Directing  Holder shall have the option to (i) direct the
Special  Servicer  not to  purchase  any such  Severely  Delinquent  Loan but to
proceed  with  a  particular  default  resolution  strategy  or  other  strategy
consistent with the servicing standards set forth in this Agreement, (ii) direct
the  Special  Servicer  to proceed  with the  purchase of such loan on the terms
proposed by the Special  Servicer,  or (iii) indicate that the Directing  Holder
intends to purchase such Severely  Delinquent  Loan, in which case the Directing
Holder shall have the sole right and option to purchase the Severely  Delinquent
Loan at the Purchase  Price;  provided,  however,  that if the Directing  Holder
fails or refuses  to deliver a written  notice of its  election  to the  Special
Servicer  within two  Business  Days after the Special  Servicer has sent to the
Directing Holder the Initial Notice, then the Directing Holder shall have deemed
to have consented to the Special  Servicer  purchasing  the Severely  Delinquent
Loan  for its  own  account.  Such  right  of such  Directing  Holder  shall  be
transferable to and exercisable by subsequent Holders of the Class X Certificate
only upon  satisfaction  of the  conditions  set forth in this Section 3.25. The
aggregate  of any such  purchases  by the  Directing  Holder of a Mortgage  Loan
pursuant to this Section 3.25(b) shall be subject to the  restriction  described
in subsection (a) above.

          (c) All rights of the  Directing  Holder  under this  Agreement  shall
terminate  immediately upon any transfer of the Class X Certificate to any other
Person,  unless (i) the Special Servicer  consents in writing to the transfer of
such  rights and (ii) the  Trustee is  provided  with a letter  from each Rating
Agency to the effect that the transfer of the rights of the Directing  Holder to
such transferee will not result in the qualification, withdrawal or downgrade of
the ratings then assigned to any Class of Certificates.

          (d) The  Directing  Holder may,  with the  consent of the  Certificate
Insurer,  by written  notice to the Special  Servicer,  terminate the rights and
obligations of the Special Servicer under this Agreement,  without cause, as and
with the  effect  set  forth in the first  paragraph  following  clause  (iv) of
Section 8.01 and appoint a successor  Special  Servicer,  provided that (i) such
successor is reasonably  acceptable to the Master  Servicer and the  Certificate
Insurer and (ii) a letter is provided to the Trustee from each Rating  Agency to

RATES AND MONTHLY PAYMENTS.

          In the event that a shortfall in any  collection on or liability  with

of the related  Mortgage  Note and this  Agreement,  the Master  Servicer,  upon
discovery or receipt of notice thereof, immediately shall deliver to the Trustee
for  deposit in the  Distribution  Account  from its own funds the amount of any
such  shortfall  and shall  indemnify  and hold  harmless  the Trust  Fund,  the
Trustee,  the Certificate  Insurer,  the Depositor and any successor servicer in
respect of any such liability. Such indemnities shall survive the termination or
discharge of this Agreement.  Notwithstanding  the foregoing,  this Section 3.26

amounts from the related Mortgagor under the terms of the related Mortgage Note,
as permitted by law.

brokerage companies on the Master Servicer's behalf, to personally, by telephone
or mail,  solicit  the  Mortgagor  under any  Mortgage  Loan for the  purpose of
refinancing such Mortgage Loan;  PROVIDED,  that the Master Servicer may solicit
any  Mortgagor  for  whom  the  Master  Servicer  has  received  a  request  for
verification of mortgage, a request for demand for payoff, a mortgagor initiated
written  or verbal  communication  indicating  a desire to  prepay  the  related
Mortgage Loan, or the mortgagor  initiates a title search;  provided further, it
is understood and agreed that  promotions  undertaken by the Master  Servicer or
any of its Affiliates  which (i) concern  optional  insurance  products or other
additional  products  or (ii) are  directed  to the  general  public  at  large,
including,  without  limitation,  mass mailings based on  commercially  acquired
mailing  lists,  newspaper,   radio  and  television  advertisements  shall  not
constitute   solicitation  under  this  Section,  nor  is  the  Master  Servicer
prohibited  from  responding  to  unsolicited  requests or  inquiries  made by a
Mortgagor or an agent of a Mortgagor.

          Section 3.28 SPECIAL SERVICER.

          With  respect to any Mortgage  Loan that becomes a Specially  Serviced
Mortgage Loan,  all servicing  responsibilities  shall be  transferred  from the
Master  Servicer  or any  Sub-Servicer  to the  Special  Servicer.  The  Special
Servicer shall, consistent with the servicing standard set forth herein, perform
the  day-to-day  servicing  functions  with respect to such  Mortgage  Loan.  In

retain the  Servicing Fee with respect to each Mortgage Loan that is a Specially
Serviced Mortgage Loan for any calendar month or part thereof that such Mortgage
Loan was a Specially  Serviced Mortgage Loan. The Special Servicer shall perform
the  duties  and  obligations  set forth in  Section  3.16 with  respect  to the

entitled to reimbursement thereof except as specifically provided for herein.

          In the event that any Specially Serviced Mortgage Loans cease to be in
default (after giving effect to any grace period) for three consecutive  months,
the Special Servicer shall transfer all servicing  responsibilities  back to the
Master Servicer or any designated Sub-Servicer and thereafter such Mortgage Loan
shall be serviced hereunder by the Master Servicer or such Sub-Servicer.

          In the  event  that  Fairbanks  Capital  Corp.  is  terminated  in its
capacity as  Sub-Servicer,  such  termination  shall have the effect  under this
Agreement of simultaneously  terminating Fairbanks Capital Corp. in its capacity
as  Special  Servicer  hereunder.  In the event of any such  termination  of the
Special Servicer, the Master Servicer shall, with the consent of the Certificate
Insurer and the Rating Agencies, appoint a successor Special Servicer.

Trustee's    website.    The    Trustee's    website    can   be   accessed   at
http://online.bankerstrust.com/invr.  The Trustee's obligations pursuant to this
Section  4.03  are  limited  to the  extent  of  its  receipt  of all  necessary
information from the Master Servicer.  The Trustee may fully rely upon and shall
have no liability with respect to information provided by the Master Servicer.

          In the case of  information  furnished  pursuant to subclauses (i) and
(ii) above,  the amounts shall be expressed in a separate  section of the report
as a dollar amount for each Class for each $1,000  original  dollar amount as of
the Cut-off Date.

          (b) Within a reasonable  period of time after the end of each calendar
year, the Trustee shall, upon written request, furnish to each Person who at any
time during the calendar year was a Certificateholder  of a Regular Certificate,
if  requested  in writing by such  Person,  such  information  as is  reasonably
necessary to provide to such Person a statement  containing the  information set
forth in  subclauses  (i) and (ii) above,  aggregated  for such calendar year or
applicable  portion  thereof  during which such Person was a  Certificateholder.
Such  obligation  of the Trustee  shall be deemed to have been  satisfied to the
extent that substantially comparable information shall be prepared and furnished
by the Trustee to Certificateholders pursuant to any requirements of the Code as
are in force from time to time.

          (c) On each Distribution  Date, the Trustee shall forward to the Class
R   Certificateholders   a  copy  of  the  reports   forwarded  to  the  Regular
Certificateholders  in  respect  of  such  Distribution  Date  with  such  other
information as the Trustee deems necessary or appropriate.

          (d) Within a reasonable  period of time after the end of each calendar
year,  the  Trustee  shall  deliver to each  Person  who at any time  during the

Person, such information as is reasonably  necessary to provide to such Person a
statement containing the information provided pursuant to the previous paragraph
aggregated  for such calendar year or applicable  portion  thereof  during which
such  Person was a Class R  Certificateholder.  Such  obligation  of the Trustee
shall  be  deemed  to have  been  satisfied  to the  extent  that  substantially
comparable  information shall be prepared and furnished to Certificateholders by
the  Trustee  pursuant to any  requirements  of the Code as from time to time in
force.

          Section 4.04 REMITTANCE REPORTS; ADVANCES.

          (a) No later than the second Business Day following each Determination
Date, the Master Servicer shall deliver to the Trustee by telecopy or electronic
mail (or by such other  means as the Master  Servicer  and the Trustee may agree
from time to time) a Remittance Report with respect to the related  Distribution
Date. Not later than the Close of Business New York time on the Master  Servicer
Remittance  Date, the Master  Servicer shall deliver or cause to be delivered to
the Trustee in addition to the  information  provided on the Remittance  Report,
such other information  reasonably  available to it with respect to the Mortgage
Loans  as the  Trustee  may  reasonably  require  to  perform  the  calculations
necessary to make the distributions  contemplated by Section 4.01 and to prepare
the statements to  Certificateholders  contemplated by Section 4.03. The Trustee
shall not be  responsible to recompute,  recalculate  or verify any  information
provided to it by the Master Servicer.

          (b) The amount of Advances to be made by the Master  Servicer  for any
Distribution  Date shall equal,  subject to Section 4.04(d),  the sum of (i) the
aggregate  amount of Monthly  Payments (net of the related  Servicing  Fee), due
during the related Due Period in respect of the Mortgage  Loans,  which  Monthly
Payments were  delinquent on a contractual  basis as of the Close of Business on
the related Determination Date and (ii) with respect to each REO Property, which
REO Property  was  acquired  during or prior to the related Due Period and as to
which REO  Property  an REO  Disposition  did not occur  during the  related Due
Period,  an amount equal to the excess,  if any, of the REO Imputed  Interest on
such REO Property  for the most  recently  ended  calendar  month,  over the net
income from such REO Property  transferred to the Distribution  Account pursuant
to Section 3.23 for distribution on such Distribution  Date. For purposes of the
preceding  sentence,  the Monthly  Payment on each Balloon  Mortgage Loan with a
delinquent  Balloon  Payment is equal to the assumed  monthly payment that would
have  been  due on  the  related  Due  Date  based  on  the  original  principal
amortization schedule for the such Balloon Mortgage Loan.

          On or  before  the  Close  of  Business  New York  time on the  Master
Servicer  Remittance  Date,  the  Master  Servicer  shall  remit in  immediately
available funds to the Trustee for deposit in the Distribution Account an amount
equal to the aggregate amount of Advances,  if any, to be made in respect of the
Mortgage Loans and REO Properties for the related  Distribution  Date either (i)
from its own funds or (ii) from the Collection  Account,  to the extent of funds
held therein for future  distribution (in which case it will cause to be made an
appropriate  entry in the records of  Collection  Account  that amounts held for
future  distribution  have been, as permitted by this Section 4.04,  used by the
Master  Servicer in discharge  of any such  Advance) or (iii) in the form of any
combination of (i) and (ii)  aggregating the total amount of Advances to be made
by the Master  Servicer with respect to the Mortgage  Loans and REO  Properties.
Any  amounts  held for future  distribution  and so used shall be  appropriately
reflected in the Master  Servicer's  records and replaced by the Master Servicer
by deposit in the Collection Account on or before any future Servicer Remittance
Date to the extent that the Available  Funds for the related  Distribution  Date
(determined  without  regard  to  Advances  to be  made on the  Master  Servicer
Remittance  Date) shall be less than the total amount that would be  distributed
to  the  Classes  of  Certificateholders   pursuant  to  Section  4.01  on  such
Distribution Date if such amounts held for future  distributions had not been so
used to make  Advances.  The Trustee will promptly  provide notice to the Master
Servicer  by  telecopy  in the event  that the  amount  remitted  by the  Master
Servicer  to the Trustee on such date is less than the  Advances  required to be
made by the Master Servicer for the related  Distribution  Date, as set forth in
the related Remittance Report.

          (c) The  obligation  of the Master  Servicer to make such  Advances is
mandatory,  notwithstanding any other provision of this Agreement but subject to
(d) below,  and, with respect to any Mortgage  Loan,  shall  continue  until the
Mortgage Loan is paid in full or until the recovery of all Liquidation  Proceeds
thereon.

          (d)  Notwithstanding  anything  herein to the contrary,  no Advance or
Servicing  Advance shall be required to be made hereunder by the Master Servicer
if such Advance or Servicing Advance would, if made, constitute a Nonrecoverable
Advance.   The  determination  by  the  Master  Servicer  that  it  has  made  a
Nonrecoverable  Advance or that any proposed  Advance or Servicing  Advance,  if
made,  would  constitute  a  Nonrecoverable  Advance,  shall be  evidenced by an
Officers'  Certificate of the Master Servicer delivered to the Depositor and the
Trustee.

          Section 4.05 PRE-FUNDING ACCOUNTS AND CAPITALIZED INTEREST ACCOUNTS.

          (a) The Trustee has heretofore established or caused to be established
and shall  hereafter  maintain or cause to be maintained  two separate  accounts
denominated" Pre-Funding Accounts",  which are and shall continue to be Eligible
Accounts  in the name of the  Trustee  and shall be  designated  "Bankers  Trust
Company of California,  N.A., as Trustee of the United PanAm Mortgage Loan Trust
1999-2,  Group I Pre-Funding  Account" and "Bankers Trust Company of California,
N.A.,  as Trustee of the  United  PanAm  Mortgage  Loan Trust  1999-2,  Group II
Pre-Funding  Account".  Each of the Pre-Funding  Accounts shall be treated as an
"outside  reserve fund" under applicable  Treasury  regulations and shall not be
part of any REMIC. Any investment earnings on the Pre-Funding  Accounts shall be
treated as owned by the Seller and will be taxable to the Seller.

          The Trustee has heretofore established or caused to be established and
shall  hereafter  maintain  or  cause to be  maintained  two  separate  accounts

Trust Company of California,  N.A., as Trustee of the United PanAm Mortgage Loan
Trust Series 1999-2,  Group I Capitalized  Interest  Account" and "Bankers Trust
Company of California,  N.A., as Trustee of the United PanAm Mortgage Loan Trust
Series 1999-2, Group II Capitalized  Interest Account".  Each of the Capitalized
Interest Accounts shall be treated as an "outside reserve fund" under applicable
Treasury regulations and shall not be part of any REMIC. Any investment earnings
on the Capitalized Interest Accounts shall be treated as owned by the Seller and
will be taxable to the Seller.

          The amount on deposit in the Pre-Funding  Accounts and the Capitalized
Interest Accounts shall be invested in Permitted  Investments in accordance with
the provisions of Section 3.12 hereof.

          (b) On the Closing Date, the Seller shall cause to be deposited in the
Group I Pre-Funding  Account and the Group II Pre-Funding Account the amounts of
$27,234,114.75 and $10,298,458.02 respectively,  and shall cause to be deposited
in the  Group I  Capitalized  Interest  Account  and the  Group  II  Capitalized
Interest Account the amounts of $244,110.34, and $94,002.75, respectively.

          (c)  On  each  Additional  Transfer  Date,  upon  satisfaction  of the
conditions set forth in Section 2.10 hereof, the Trustee shall withdraw from the
related  Pre-Funding  Accounts an amount  equal to 100% of the  aggregate of the
Cut-off Date  Principal  Balances of the  Additional  Mortgage Loans sold to the
Trust for  inclusion  in Loan  Group I or Loan  Group II, as the case may be, on
such  Additional  Transfer  Date and pay such amount to or upon the order of the
Seller.

          (d) On the Business  Day prior to the  Distribution  Date  immediately
following the Due Period in which the Pre-Funding Period ends, the Trustee shall
(i)  withdraw  the  Unutilized  Pre-Funding  Amount,  if any,  from  each of the
Pre-Funding  Accounts,  (ii)  promptly  deposit each amount in the  Distribution
Account and (iii)  distribute  each amount to the related  Certificate  Group on
such Distribution Date pursuant to Section 2.11 hereof.

          The amount  deposited  in the  Distribution  Account  pursuant  to the
preceding paragraph shall be net of any Pre-Funding Earnings.

          (e) On the Business Day prior to each Distribution  Date,  through the
Distribution Date immediately  following the Due Period in which the Pre-Funding
Period ends,  the Trustee shall  transfer from each  Pre-Funding  Account to the
Distribution  Account  the  Pre-Funding  Earnings,  if any,  applicable  to such
Distribution  Date and  shall  distribute  such  amount  to the  REMIC I Regular
Interests  corresponding to the related  Certificate  Group on such Distribution
Date pursuant to Section 4.02 hereof.

          (f) On the Business Day prior to each Distribution  Date,  through the
Distribution Date immediately  following the Due Period in which the Pre-Funding
Period ends, the Trustee shall transfer from each  Capitalized  Interest Account
to the Distribution  Account the related Capitalized  Interest  Requirement,  if
any, for such  Distribution Date and shall distribute such amount to the REMIC I
Regular  Interests  corresponding  to the  related  Certificate  Group  on  such
Distribution Date pursuant to Section 4.01 hereof.

          (g)  All  amounts,  if  any,  remaining  in the  Capitalized  Interest
Accounts  on the  Distribution  Date  following  the Due  Period  in  which  the
Pre-Funding  Period ends shall be withdrawn by the Trustee from the  Capitalized
Interest Accounts and deposited in the Distribution Account on such date.


                                    ARTICLE V

                                THE CERTIFICATES

          Section 5.01 THE CERTIFICATES.

          Each of the  Class  A,  Class  X and  Class R  Certificates  shall  be
substantially  in the forms annexed hereto as exhibits,  and shall,  on original
issue,  be executed,  authenticated  and delivered by the Trustee to or upon the
order of the Depositor  concurrently with the sale and assignment to the Trustee
of the Trust Fund.  Each Class of the Class A  Certificates  shall be  initially
evidenced by one or more Certificates  representing a Percentage Interest with a
minimum dollar  denomination of $50,000 and integral dollar  multiples of $1,000
in  excess  thereof,   except  that  one  Certificate  of  each  such  Class  of
Certificates  may  be in a  different  denomination  so  that  the  sum  of  the
denominations  of all  outstanding  Certificates  of such Class  shall equal the
Class Certificate Principal Balance of such Class on the Closing Date. The Class
R  Certificates  are issuable only in minimum  Percentage  Interests of 25%. The
Class X  Certificate  is issuable only as a single  certificate  in a Percentage
Interest of 100%.

          The Certificates shall be executed on behalf of the Trust by manual or
facsimile  signature  on  behalf  of  the  Trustee  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 Trustee shall bind the Trust,  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 such Certificate  shall have been
manually  authenticated  by the Trustee  substantially  in the form provided for
herein,  and such  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.  Subject to Section 5.02(c),  the Class A Certificates
shall be Book-Entry Certificates. The Class X and Class R Certificates shall not
be Book-Entry Certificates.

          Section 5.02 REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES.

          (a) The Certificate  Registrar shall cause to be kept at the Corporate
Trust  Office a  Certificate  Register  in  which,  subject  to such  reasonable
regulations as it may prescribe, the Certificate Registrar shall provide for the
registration of  Certificates  and of transfers and exchanges of Certificates as
herein provided.  The Trustee shall initially serve as Certificate Registrar for
the  purpose  of  registering   Certificates  and  transfers  and  exchanges  of
Certificates as herein provided.

          Upon surrender for  registration of transfer of any Certificate at any
office  or agency  of the  Certificate  Registrar  maintained  for such  purpose
pursuant  to the  foregoing  paragraph  and, in the case of a Class X or Class R
Certificate, upon satisfaction of the conditions set forth below, the Trustee on
behalf of the Trust shall execute,  authenticate and deliver, in the name of the
designated  transferee or transferees,  one or more new Certificates of the same
aggregate Percentage Interest.

          At the option of the Certificateholders, Certificates may be exchanged
for  other  Certificates  in  authorized  denominations  and the same  aggregate
Percentage Interests,  upon surrender of the Certificates to be exchanged at any
such  office  or  agency.  Whenever  any  Certificates  are so  surrendered  for
exchange,  the Trustee shall execute on behalf of the Trust and 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 (if so required by the Trustee or the  Certificate
Registrar) be duly  endorsed by, or be  accompanied  by a written  instrument of
transfer satisfactory to the Trustee and the Certificate Registrar duly executed
by, the Holder thereof or his attorney duly authorized in writing.

          (b)  Except  as  provided  in  paragraph  (c)  below,  the  Book-Entry
Certificates  shall at all times remain registered in the name of the Depository
or its nominee and at all times: (i)  registration of such  Certificates may not
be transferred by the Trustee except to another Depository;  (ii) the Depository
shall maintain  book-entry  records with respect to the  Certificate  Owners and
with respect to ownership and transfers of such  Certificates;  (iii)  ownership
and  transfers  of  registration  of  such  Certificates  on  the  books  of the
Depository shall be governed by applicable rules  established by the Depository;
(iv) the  Depository  may  collect  its usual and  customary  fees,  charges and
expenses  from  its  Depository  Participants;  (v) the  Trustee  shall  for all
purposes deal with the Depository as representative of the Certificate Owners of
the  Certificates  for purposes of  exercising  the rights of Holders under this
Agreement,  and requests  and  directions  for and votes of such  representative
shall  not be  deemed  to be  inconsistent  if they are  made  with  respect  to
different  Certificate  Owners;  (vi) the  Trustee  may rely and  shall be fully
protected in relying upon  information  furnished by the Depository with respect
to its Depository Participants and furnished by the Depository Participants with
respect to indirect  participating  firms and Persons shown on the books of such
indirect participating firms as direct or indirect Certificate Owners; and (vii)
the  direct  participants  of the  Depository  shall  have no rights  under this
Agreement under or with respect to any of the Certificates  held on their behalf
by the  Depository,  and the  Depository  may be treated by the  Trustee and its
agents,  employees,  officers  and  directors  as  the  absolute  owner  of  the
Certificates for all purposes whatsoever.

          All transfers by Certificate  Owners of Book-Entry  Certificates shall
be  made  in  accordance  with  the  procedures  established  by the  Depository
Participant  or  brokerage  firm  representing  such  Certificate  Owners.  Each
Depository   Participant   shall  only  transfer   Book-Entry   Certificates  of
Certificate Owners that it represents or of brokerage firms for which it acts as
agent in accordance with the Depository's normal procedures.  The parties hereto
are hereby authorized to execute a Letter of Representations with the Depository
or take such  other  action as may be  necessary  or  desirable  to  register  a
Book-Entry  Certificate to the Depository.  In the event of any conflict between
the terms of any such Letter of Representation and this Agreement,  the terms of
this Agreement shall control.

          (c) If (i) (x) the Depository or the Depositor  advises the Trustee in
writing that the Depository is no longer  willing or able to discharge  properly
its  responsibilities  as  Depository  and (y) the Trustee or the  Depositor  is
unable to locate a qualified successor,  (ii) the Depositor, at its sole option,
with the consent of the  Trustee,  elects to  terminate  the  book-entry  system
through the  Depository  or (iii) after the  occurrence  of a Servicer  Event of
Termination,  the  Certificate  Owners  of each  Class of  Class A  Certificates
representing  Percentage Interests of such Classes aggregating not less than 51%
advises the Trustee and Depository through the Financial  Intermediaries and the
Depository  Participants in writing that the continuation of a book-entry system
through  the  Depository  to  the  exclusion  of  definitive,  fully  registered
certificates (the "Definitive  Certificates") to Certificate Owners is no longer
in the best interests of the Certificate Owners,  Definitive  Certificates shall
be issued  in  exchange  for  Book-Entry  Certificates.  Upon  surrender  to the
Certificate  Registrar  of  the  Book-Entry   Certificates  by  the  Depository,
accompanied by registration  instructions  from the Depository for registration,
the Trustee shall, at the Depositor's expense, in the case of (ii) above, or the
Seller's expense,  in the case of (i) and (iii) above,  execute on behalf of the
Trust and  authenticate the Definitive  Certificates.  Neither the Depositor nor
the Trustee 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,  the Trustee,  the
Certificate  Registrar,  the Master Servicer, any Paying Agent and the Depositor
shall recognize the Holders of the Definitive Certificates as Certificateholders
hereunder.

          (d) Except  with  respect to the  initial  transfer of the Class X and
Class R  Certificates  by the  Depositor,  no  transfer,  sale,  pledge or other
disposition  of any Class X or Class R  Certificate  shall be made  unless  such
disposition is exempt from the  registration  requirements of the Securities Act
of 1933, as amended (the "1933 Act"),  and any applicable  state securities laws
or is made in  accordance  with the 1933 Act and laws.  In the event of any such
transfer,  (i)  unless  such  transfer  is made in  reliance  upon Rule 144A (as
evidenced by the investment  letter  delivered to the Trustee,  in substantially
the form  attached  hereto as Exhibit K under the 1933 Act,  the Trustee and the
Depositor  shall  require a written  Opinion of Counsel  (which may be  in-house
counsel) acceptable to and in form and substance reasonably  satisfactory to the
Trustee  and  the  Depositor  that  such  transfer  may be made  pursuant  to an
exemption,  describing the applicable exemption and the basis therefor, from the
1933 Act or is being made  pursuant  to the 1933 Act,  which  Opinion of Counsel
shall not be an expense  of the  Trustee or the  Depositor  or (ii) the  Trustee
shall  require  the   transferor  to  execute  a  transferor   certificate   (in
substantially  the form  attached  hereto as  Exhibit M) and the  transferee  to
execute an  investment  letter (in  substantially  the form  attached  hereto as
Exhibit K) acceptable to and in form and substance  reasonably  satisfactory  to
the  Depositor  and the Trustee  certifying to the Depositor and the Trustee the
facts surrounding such transfer, which investment letter shall not be an expense
of the Trustee or the Depositor.  The Holder of a Class X or Class R Certificate
desiring to effect such transfer shall,  and does hereby agree to, indemnify the
Trustee and the Depositor  against any liability that may result if the transfer
is not so exempt or is not made in accordance with such federal and state laws.

          No transfer of a Class X or Class R  Certificate  shall be made unless
the Trustee shall have received either (i) a representation  from the transferee
of such Certificate, acceptable to and in form and substance satisfactory to the
Trustee and the Depositor,  (such requirement is satisfied only by the Trustee's
receipt of a representation letter from the transferee substantially in the form
of Exhibit J hereto, as appropriate),  to the effect that such transferee is not
an employee  benefit  plan or  arrangement  subject to Section 406 of ERISA or a
plan subject to Section 4975 of the Code (collectively,  a "Plan"), nor a Person
acting on  behalf  of any such  Plan nor  using  the  assets of any such Plan to
effect such  transfer or (ii) (in the case of the Class X  Certificates)  if the
purchaser is an insurance  company,  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 PTCE 95-60 or (iii)
in  the  case  of  any  such  Class  X or  Class  R  Certificate  presented  for
registration  in the name of a Plan (or comparable  provisions of any subsequent
enactments),  or a trustee of any such Plan or any other Person acting on behalf
of any such Plan or using such Plan's assets, an Opinion of Counsel satisfactory
to the Trustee  which  Opinion of Counsel  shall not be an expense of either the
Trustee or the Trust,  addressed to the Trustee, to the effect that the purchase
or holding of such Class X or Class R Certificate  will not result in the assets
of the Trust being  deemed to be "plan  assets"  and  subject to the  prohibited
transaction provisions of ERISA and the Code and will not subject the Trustee to
any obligation in addition to those expressly undertaken in this Agreement or to
any  liability.  For  purposes  of clause (i) of the  preceding  sentence,  such
representation  shall  be  deemed  to  have  been  made  to the  Trustee  by the
transferee's  acceptance of a Class X or Class R Certificate  (or the acceptance
by a Certificate Owner of the beneficial interest in any such Class X or Class R
Certificate)  unless the Trustee  shall have  received  from the  transferee  an
alternative  representation  acceptable in form and substance to the  Depositor.
Notwithstanding  anything else to the contrary herein, any purported transfer of
a Class X or Class R Certificate  to or on behalf of a Plan without the delivery
to the Trustee of an Opinion of Counsel satisfactory to the Trustee as described
above shall be void and of no effect.

          Each Person who has or who acquires any Ownership  Interest in a Class
R 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  appointed the Depositor or its designee as its  attorney-in-fact to
negotiate the terms of any mandatory  sale under clause (v) below and to execute
all  instruments of transfer and to do all other things  necessary in connection
with any such  sale,  and the  rights of each  Person  acquiring  any  Ownership
Interest  in a  Class R  Certificate  are  expressly  subject  to the  following
provisions:

          (i) Each Person holding or acquiring any Ownership Interest in a Class
     R Certificate shall be a Permitted Transferee and shall promptly notify the
     Trustee of any  change or  impending  change in its  status as a  Permitted
     Transferee.

          (ii) No  Person  shall  acquire  an  Ownership  Interest  in a Class R
     Certificate  unless  such  Ownership  Interest  is  a  pro  rata  undivided
     interest.

          (iii)  In  connection  with any  proposed  transfer  of any  Ownership
     Interest  in a Class R  Certificate,  the Trustee  shall as a condition  to
     registration of the transfer, require delivery to it, in form and substance
     satisfactory to it, of each of the following:

                  A. an  affidavit  in the form of  Exhibit  L  hereto  from the
            proposed  transferee  to  the  effect  that  such  transferee  is  a
            Permitted  Transferee  and that it is not  acquiring  its  Ownership
            Interest  in the  Class R  Certificate  that is the  subject  of the
            proposed transfer as a nominee,  trustee or agent for any Person who
            is not a Permitted Transferee; and

                  B. a covenant of the  proposed  transferee  to the effect that
            the  proposed  transferee  agrees to be bound by and to abide by the
            transfer restrictions applicable to the Class R Certificates.

          (iv) Any attempted or purported  transfer of any Ownership Interest in
     a Class R Certificate  in violation of the provisions of this Section shall
     be  absolutely  null and void and shall  vest no  rights  in the  purported
     transferee.  If  any  purported  transferee  shall,  in  violation  of  the
     provisions of this Section, become a Holder of a Class R Certificate,  then
     the prior Holder of such Class R Certificate that is a Permitted Transferee
     shall,  upon  discovery that the  registration  of transfer of such Class R
     Certificate  was not in fact permitted by this Section,  be restored to all
     rights  as  Holder  thereof  retroactive  to the  date of  registration  of
     transfer  of such  Class R  Certificate.  The  Trustee  shall  be  under no
     liability  to any  Person for any  registration  of  transfer  of a Class R
     Certificate that is in fact not permitted by this Section or for making any
     distributions  due on such Class R  Certificate  to the  Holder  thereof or
     taking any other action with respect to such Holder under the provisions of
     this Agreement so long as the Trustee  received the documents  specified in
     clause (iii). The Trustee shall be entitled to recover from any Holder of a
     Class R Certificate that was in fact not a Permitted Transferee at the time
     such  distributions  were  made  all  distributions  made on  such  Class R
     Certificate.  Any such  distributions  so recovered by the Trustee shall be
     distributed  and delivered by the Trustee to the prior Holder of such Class
     R Certificate that is a Permitted Transferee.

          (v) If any  Person  other than a  Permitted  Transferee  acquires  any
     Ownership   Interest  in  a  Class  R  Certificate   in  violation  of  the
     restrictions in this Section, then the Trustee shall have the right but not
     the obligation, without notice to the Holder of such Class R Certificate or
     any other  Person  having an  Ownership  Interest  therein,  to notify  the
     Depositor to arrange for the sale of such Class R Certificate. The proceeds
     of such sale, net of commissions (which may include  commissions payable to
     the Depositor or its affiliates in connection with such sale), expenses and
     taxes due, if any,  will be remitted by the Trustee to the previous  Holder
     of such Class R Certificate that is a Permitted Transferee,  except that in
     the event  that the  Trustee  determines  that the  Holder of such  Class R
     Certificate  may be liable for any  amount  due under  this  Section or any
     other   provisions   of  this   Agreement,   the  Trustee  may  withhold  a
     corresponding  amount from such remittance as security for such claim.  The
     terms and  conditions of any sale under this clause (v) shall be determined
     in the sole  discretion  of the  Trustee  and it shall not be liable to any
     Person having an Ownership Interest in a Class R Certificate as a result of
     its exercise of such discretion.

          (vi) If any Person  other than a  Permitted  Transferee  acquires  any
     Ownership   Interest  in  a  Class  R  Certificate   in  violation  of  the
     restrictions  in this Section,  then the Trustee upon receipt of reasonable
     compensation  will  provide to the  Internal  Revenue  Service,  and to the
     persons specified in Sections  860E(e)(3) and (6) of the Code,  information
     needed to compute the tax imposed under  Section  860E(e)(5) of the Code on
     transfers of residual interests to disqualified organizations.

The  foregoing  provisions  of this  Section  shall cease to apply to  transfers
occurring  on or after the date on which there shall have been  delivered to the
Trustee,  in  form  and  substance  satisfactory  to the  Trustee,  (i)  written
notification  from each Rating  Agency that the removal of the  restrictions  on
Transfer  set  forth in this  Section  will not  cause  such  Rating  Agency  to
downgrade its rating of the  Certificates  and (ii) an Opinion of Counsel to the
effect that such removal  will not cause any REMIC  hereunder to fail to qualify
as a REMIC.

          (e) All rights of the  Directing  Holder  under this  Agreement  shall
terminate  immediately upon any transfer of the Class X Certificate to any other
Person,  unless (i) the Special Servicer  consents in writing to the transfer of
such  rights and (ii) the  Trustee is  provided  with a letter  from each Rating
Agency to the effect that the transfer of the rights of the Directing  Holder to
such transferee will not result in the qualification, withdrawal or downgrade of
the ratings then assigned to any Class of Certificates.

          (f) No service charge shall be made for any  registration  of transfer
or exchange of  Certificates  of any Class,  but the  Certificate  Registrar may
require 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.

          All Certificates  surrendered for registration of transfer or exchange
shall be cancelled by the Certificate  Registrar and disposed of pursuant to its
standard procedures.

          Section 5.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

          If (i) any mutilated  Certificate is  surrendered  to the  Certificate
Registrar or the Certificate  Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate and (ii) there is delivered to
the Trustee,  the  Depositor  and the  Certificate  Registrar  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  or the  Certificate  Registrar  that  such
Certificate  has been  acquired  by a bona fide  purchaser,  the  Trustee  shall
execute on behalf of the Trust,  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 Percentage Interest.  Upon the issuance of any new
Certificate  under this Section,  the Trustee or the  Certificate  Registrar 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  Trustee  and  the  Certificate  Registrar)  in
connection therewith. Any duplicate Certificate issued pursuant to this Section,
shall constitute  complete and indefeasible  evidence of ownership in the Trust,
as  if  originally  issued,  whether  or  not  the  lost,  stolen  or  destroyed
Certificate shall be found at any time.

          Section 5.04 PERSONS DEEMED OWNERS.

          The Master  Servicer,  the  Depositor,  the Trustee,  the  Certificate
Registrar, any Paying Agent and any agent of the Master Servicer, the Depositor,
the  Certificate  Insurer,  the Certificate  Registrar,  any Paying Agent or the
Trustee  may  treat  the  Person,  including  a  Depository,  in whose  name any
Certificate  is registered as the owner of such  Certificate  for the purpose of
receiving  distributions  pursuant  to Section  4.01 and for all other  purposes
whatsoever, and none of the Master Servicer, the Trust, the Certificate Insurer,
the  Trustee  nor any agent of any of them  shall be  affected  by notice to the
contrary.

          Section 5.05 APPOINTMENT OF PAYING AGENT.

          (a) The Paying Agent shall make  distributions  to  Certificateholders
from the  Distribution  Account  pursuant to Section  4.01 and shall  report the
amounts of such distributions to the Trustee. The duties of the Paying Agent may
include  the  obligation  (i) to  withdraw  funds  from the  Collection  Account
pursuant  to Section  3.11(a)  and for the  purpose of making the  distributions
referred to above and (ii) to distribute  statements and provide  information to
Certificateholders  as required  hereunder.  The Paying Agent hereunder shall at
all times be an entity duly  incorporated and validly existing under the laws of
the United States of America or any state thereof, authorized under such laws to
exercise  corporate  trust powers and subject to  supervision  or examination by
federal or state  authorities.  The Paying Agent shall initially be the Trustee.
The Trustee may appoint a successor to act as Paying  Agent,  which  appointment
shall be reasonably satisfactory to the Depositor and the Certificate Insurer.

          (b) The  Trustee  shall  cause the  Paying  Agent  (if other  than the
Trustee)  to execute  and  deliver to the  Trustee an  instrument  in which such
Paying  Agent shall agree with the Trustee that such Paying Agent shall hold all
sums, if any, held by it for payment to the  Certificateholders in trust for the
benefit of the Certificateholders entitled thereto until such sums shall be paid
to such  Certificateholders  and  shall  agree  that it  shall  comply  with all
requirements  of the Code  regarding the  withholding  of payments in respect of
Federal income taxes due from  Certificate  Owners and otherwise comply with the
provisions of this Agreement applicable to it.

                THE SELLER, THE MASTER SERVICER AND THE DEPOSITOR

          Section  6.01  LIABILITY  OF THE SELLER,  THE MASTER  SERVICER AND THE
DEPOSITOR.

          The  Seller  and the  Master  Servicer  shall be liable in  accordance
herewith  only to the extent of the  obligations  specifically  imposed upon and
undertaken by the Seller or the Master Servicer, as the case may be, herein. The
Depositor  shall be  liable in  accordance  herewith  only to the  extent of the
obligations specifically imposed upon and undertaken by the Depositor.

          Section  6.02  MERGER  OR  CONSOLIDATION  OF,  OR  ASSUMPTION  OF  THE
OBLIGATIONS OF, THE SELLER, THE MASTER SERVICER OR THE DEPOSITOR.

          Any entity into which the Seller,  Master Servicer or Depositor may be
merged or consolidated,  or any entity resulting from any merger,  conversion or
consolidation to which the Seller, the Master Servicer or the Depositor shall be
a party, or any corporation succeeding to the business of the Seller, the Master
Servicer or the  Depositor,  shall be the  successor  of the Seller,  the Master
Servicer or the Depositor, as the case may be, hereunder,  without the execution
or  filing  of any paper or any  further  act on the part of any of the  parties
hereto, anything herein to the contrary notwithstanding; PROVIDED, HOWEVER, that
the successor Master Servicer shall satisfy all the requirements of Section 7.02
with respect to the qualifications of a successor Master Servicer.

          Section  6.03  LIMITATION  ON  LIABILITY  OF THE MASTER  SERVICER  AND
OTHERS.

          Neither the Master  Servicer  nor any of the  directors or officers or
employees or agents of the Master  Servicer  shall be under any liability to the
Trust or the  Certificateholders for any action taken or for refraining from the
taking of any  action by the Master  Servicer  in good  faith  pursuant  to this
Agreement,  or for errors in judgment;  PROVIDED,  HOWEVER,  that this provision
shall not protect the Master  Servicer or any such Person  against any liability
which would otherwise be imposed by reason of its willful misfeasance, bad faith
or negligence in the  performance of duties of the Master  Servicer or by reason
of its  failure to perform  its  obligations  and  duties  hereunder;  PROVIDED,
FURTHER,  that this  provision  shall not be  construed  to  entitle  the Master
Servicer to indemnity in the event that amounts  advanced by the Master Servicer
to retire any senior  lien  exceed  Liquidation  Proceeds  (in excess of related
liquidation  expenses)  realized with respect to the related  Mortgage Loan. The
preceding  sentence  shall not  limit the  obligations  of the  Master  Servicer
pursuant to Section  8.05.  The Master  Servicer  and any director or officer or
employee or agent of the Master  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 Master Servicer and any director or officer
or employee or agent of the Master  Servicer  shall be  indemnified by the Trust
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 related to any specific Mortgage Loan or Mortgage
Loans  (except  as any such  loss,  liability  or  expense  shall  be  otherwise
reimbursable  pursuant to this  Agreement)  and any loss,  liability  or expense
incurred by reason of its willful  misfeasance,  bad faith or  negligence in the
performance  of duties  hereunder  or by reason of its  failure to  perform  its
obligations  and duties  hereunder.  The Master  Servicer may undertake any such
action which it may deem  necessary  or desirable in respect of this  Agreement,
and the  rights  and  duties of the  parties  hereto  and the  interests  of the
Certificateholders  hereunder. In such event, unless the Depositor or the Master
Servicer  acts  without  the  consent  of the  Certificate  Insurer  prior to an
Certificate  Insurer  Default or without the consent of Holders of  Certificates
entitled  to at least 51% of the  Voting  Rights  after an  Certificate  Insurer
Default,  the  reasonable  legal  expenses  and  costs  of such  action  and any
liability  resulting  therefrom shall be expenses,  costs and liabilities of the
Trust and the Master  Servicer shall be entitled to be reimbursed  therefor only
pursuant to Sections  4.01(a)(A)(x)  and  4.01(a)(B)(x).  The Master  Servicer's
right to indemnity or reimbursement pursuant to this Section shall be subject to
the  payment  priority  described  in  Section  4.01(a)  and shall  survive  any
resignation or termination  of the Master  Servicer  pursuant to Section 6.04 or
7.01 with respect to any losses, expenses, costs or liabilities arising prior to
such  resignation or termination  (or arising from events that occurred prior to
such  resignation  or  termination).  This  paragraph  shall apply to the Master
Servicer  solely  in  its  capacity  as  Servicer  hereunder  and  in  no  other
capacities.

          Subject to the provisions of Section 7.01 and Section 6.02, the Master
Servicer shall not resign from the  obligations  and duties hereby imposed on it
except (i) upon  determination that the performance of its obligations or duties
hereunder  are no longer  permissible  under  applicable  law or are in material
conflict by reason of applicable law with any other activities  carried on by it
or its  subsidiaries or Affiliates,  the other activities of the Master Servicer
so causing such a conflict  being of a type and nature  carried on by the Master
Servicer or its subsidiaries or Affiliates at the date of this Agreement or (ii)
upon  satisfaction  of the  following  conditions:  (a) the Master  Servicer has
proposed a  successor  servicer  to the  Trustee in  writing  and such  proposed
successor servicer is acceptable to the Trustee and the Certificate Insurer; (b)
each Rating  Agency  shall have  delivered a letter to the Trustee  prior to the
appointment of the successor  servicer stating that the proposed  appointment of
such  successor  servicer as Master  Servicer  hereunder  will not result in the
reduction or withdrawal of the then current  rating of the Regular  Certificates
or the ratings that are in effect  without  taking into account the  Certificate
Insurance Policy and (c) such proposed  successor  servicer is acceptable to the
Certificate Insurer, as evidenced by a letter to the Trustee; PROVIDED, HOWEVER,
that no such  resignation by the Master  Servicer shall become  effective  until
such  successor  servicer or, in the case of (i) above,  the Trustee  shall have
assumed the Master Servicer's  responsibilities and obligations hereunder or the
Trustee shall have  designated a successor  servicer in accordance  with Section
7.02.  Any  such   resignation   shall  not  relieve  the  Master   Servicer  of
responsibility for any of the obligations specified in Sections 7.01 and 7.02 as
obligations  that survive the resignation or termination of the Master Servicer.
Any  such  determination  permitting  the  resignation  of the  Master  Servicer
pursuant to clause (i) above shall be evidenced by an Opinion of Counsel to such
effect  delivered  to  the  Trustee.  Any  such  determination   permitting  the
resignation  of the Master  Servicer shall be evidenced by an Opinion of Counsel
to such effect delivered to the Trustee.

          Section 6.05 DELEGATION OF DUTIES.

          In the ordinary  course of  business,  the Master  Servicer,  with the
consent of the  Certificate  Insurer at any time may  delegate any of its duties
hereunder to any Person, including any of its Affiliates,  who agrees to conduct
such  duties  in  accordance  with  standards  comparable  to those set forth in
Section  3.01.  Such  delegation  shall not relieve  the Master  Servicer of its
liabilities  and  responsibilities  with  respect  to such  duties and shall not
constitute a resignation within the meaning of Section 6.04. The Master Servicer
shall provide the Trustee and the Certificate Insurer with 60 days prior written
notice prior to the delegation of any of its duties to any Person other than any
of the Master Servicer's Affiliates or their respective successors and assigns.

          Section 6.06 RESERVED.

          Each  of  the  Seller  and  the  Master   Servicer  shall  afford  the
Certificate  Insurer,  upon  reasonable  notice,  during normal  business hours,
access  to all  records  maintained  by the  Seller  and  the  Master  Servicer,
respectively,  in respect of its rights and obligations  hereunder and access to
officers of the Master Servicer and the Seller responsible for such obligations.
Upon request, the Master Servicer and the Seller, respectively, shall furnish to
the Certificate Insurer its most recent publicly available financial  statements
and such other  information  relating to its capacity to perform its obligations
under this Agreement.

Servicer  (and to the  Trustee  if  given  by  Holders  of  Certificates  or the

Servicer  as  servicer  under  this  Agreement.  Any such  notice to the  Master
Servicer  shall  also be given to each  Rating  Agency,  the  Depositor  and the
Seller.  On or after the receipt by the Master  Servicer  (and by the Trustee if
such notice is given by the Holders or the Certificate  Insurer) of such written
notice,  all authority and power of the Master  Servicer  under this  Agreement,
whether with respect to the  Certificates  or the Mortgage  Loans or  otherwise,
shall pass to and be vested in the Trustee or another  successor Master Servicer
designated by the Certificate  Insurer pursuant to and under this Section;  and,
without limitation, and the Trustee (or such other successor Master Servicer) is
hereby authorized and empowered to execute and deliver,  on behalf of the Master
Servicer,  as  attorney-in-fact  or  otherwise,  any and all documents and other
instruments,  and to do or  accomplish  all other  acts or things  necessary  or

the  responsibilities  and rights of the Master Servicer  hereunder,  including,
without limitation,  the delivery to the Trustee (or such other successor Master
Servicer) of all  documents  and records  requested by it to enable it to assume
the Master  Servicer's  functions under this Agreement  within ten Business Days
subsequent to such notice,  the transfer  within one Business Day  subsequent to
such notice to the Trustee (or the applicable successor Master Servicer) and the
Certificate  Insurer for the administration by it of all cash amounts that shall

any REO  Property  received by the Master  Servicer.  All  reasonable  costs and
expenses  (including  attorneys' fees) incurred in connection with  transferring
the Mortgage Files to the successor  Master Servicer and amending this Agreement
to reflect such succession as Master Servicer  pursuant to this Section shall be
paid by the predecessor  Master Servicer (or if the predecessor  Master Servicer
is the Trustee,  the initial Master  Servicer) upon  presentation  of reasonable
documentation of such costs and expenses.

          (c) The  Master  Servicer  hereby  covenants  and agrees to act as the
Master  Servicer  under this  Agreement for an initial  term,  commencing on the
Closing Date and ending on December 31, 1999,  which term may be extended by the
Certificate  Insurer for successive  terms of three calendar months  thereafter,
until the  termination of the Trust Fund pursuant to Article X. Each such notice
of extension (a "Servicer Extension Notice"),  if any, shall be delivered by the
Certificate Insurer to the Trustee,  the Depositor and the Master Servicer.  The
Master  Servicer  hereby  agrees  that,  upon its  receipt of any such  Servicer
Extension Notice, the Master Servicer shall become bound for the duration of the
term  covered  by such  Servicer  Extension  Notice to  continue  as the  Master
Servicer  subject  to and in  accordance  with  the  other  provisions  of  this
Agreement.  The Master  Servicer  agrees that if as of the fifteenth  (15th) day
prior to the last day of any term of the Master  Servicer  the  Master  Servicer
shall not have  received  any  Servicer  Extension  Notice from the  Certificate
Insurer, the Master Servicer shall within five (5) days thereafter, give written
notice of such  non-receipt  to the  Certificate  Insurer,  the  Trustee and the
Depositor.  The  failure  of the  Certificate  Insurer  to  deliver  a  Servicer
Extension  Notice by the end of a calendar term shall result in the  termination
of the Master Servicer.

          Section 7.02 TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

          (a) From and after the date the Master  Servicer (and the Trustee,  if
notice is sent by the  Holders)  receives a notice of  termination  pursuant  to
Section  7.01 or 6.04,  or the  Master  Servicer  fails to  receive  a  Servicer
Extension  Notice  pursuant  to  Section  7.01(c),  the  Trustee  (or such other
successor  Master Servicer  designated by the Certificate  Insurer) shall be the
successor  in all  respects to the Master  Servicer in its  capacity as servicer
under this Agreement and 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 by the terms and provisions hereof arising
on and after its  succession.  As  compensation  therefor,  the Trustee (or such
other successor Master  Servicer) shall be entitled to such  compensation as the
Master  Servicer  would have been  entitled  to  hereunder  if no such notice of
termination had been given (or in the case of a successor  Master Servicer other
than the Trustee,  such compensation as is agreed to by the Certificate  Insurer
and such other successor Master Servicer). Notwithstanding the above, (i) if the
Trustee is unwilling to act as successor  Master Servicer or (ii) if the Trustee
is legally  unable so to act, the Trustee  shall  appoint or petition a court of
competent  jurisdiction  to appoint,  any  established  housing and home finance
institution,  bank or other mortgage loan or home equity loan servicer  having a
net worth of not less than  $50,000,000 as the successor to the Master  Servicer
hereunder in the assumption of all or any part of the  responsibilities,  duties
or liabilities of the Master Servicer hereunder;  provided, that the appointment
of any such successor  Master  Servicer  shall be acceptable to the  Certificate
Insurer,  as evidenced by the  Certificate  Insurer's prior written consent and,
provided further, will not result in the qualification,  reduction or withdrawal
of the ratings  assigned to the  Certificates  or the ratings that are in effect
without  taking into  account  the  Certificate  Insurance  Policy by the Rating
Agencies  as  evidenced  by a letter to such  effect  from the Rating  Agencies.
Pending appointment of a successor to the Master Servicer hereunder,  unless the
Trustee is  prohibited  by law from so  acting,  the  Trustee  shall act in such
capacity as  hereinabove  provided.  In  connection  with such  appointment  and
assumption,  the  successor  shall be  entitled to receive  compensation  out of
payments  on Mortgage  Loans in an amount  equal to the  compensation  which the
Master Servicer would otherwise have received  pursuant to Section 3.18 (or such
other  compensation as the Certificate  Insurer and such successor shall agree).
The appointment of a successor Master Servicer shall not affect any liability of
the predecessor Master Servicer which may have arisen under this Agreement prior
to its termination as Master  Servicer to pay any deductible  under an insurance
policy pursuant to Section 3.14 or to indemnify the Trustee  pursuant to Section
3.26),  nor shall  any  successor  Master  Servicer  be  liable  for any acts or
omissions of the  predecessor  Master  Servicer or for any breach by such Master
Servicer of any of its representations or warranties  contained herein or in any
related  document or agreement.  The Trustee and such successor  shall take such
action,  consistent with this Agreement, as shall be necessary to effectuate any
such succession.

          (b) Any successor,  including the Trustee,  to the Master  Servicer as
master servicer shall during the term of its service as master servicer continue
to   service   and   administer   the   Mortgage   Loans  for  the   benefit  of
Certificateholders  and the Certificate  Insurer, and maintain in force a policy
or policies of insurance covering errors and omissions in the performance of its
obligations as Master  Servicer  hereunder and a Fidelity Bond in respect of its
officers,  employees and agents to the same extent as the Master  Servicer is so
required pursuant to Section 3.14.

          Section 7.03 WAIVER OF DEFAULTS.

          The Certificate  Insurer or the Majority  Certificateholders  may with
the consent of the  Certificate  Insurer,  on behalf of all  Certificateholders,
waive any events permitting  removal of the Master Servicer as servicer pursuant
to this Article VII, PROVIDED, HOWEVER, that the Majority Certificateholders may
not waive a default in making a required  distribution on a Certificate  without
the  consent  of the  Holder  of such  Certificate.  Upon any  waiver  of a past
default, such default shall cease to exist and any Servicer Event of Termination
arising  therefrom  shall be deemed to have been  remedied for every  purpose of
this  Agreement.  No such waiver shall extend to any subsequent or other default
or impair any right consequent thereto except to the extent expressly so waived.
Notice of any such waiver shall be given by the Trustee to the Rating Agencies.

          Section 7.04 NOTIFICATION TO CERTIFICATEHOLDERS.

          (a) Upon any  termination  or  appointment  of a successor  the Master
Servicer  pursuant to this Article VII or Section  6.04,  the Trustee shall give
prompt written notice thereof to the Certificate  Insurer,  the PMI Insurer, the
Certificateholders  at their respective  addresses  appearing in the Certificate
Register and each Rating Agency.

          (b) No later  than 60 days  after the  occurrence  of any event  which
constitutes or which, with notice or a lapse of time or both, would constitute a
Servicer Event of Termination for five Business Days after a Responsible Officer
of the Trustee  becomes aware of the  occurrence  of such an event,  the Trustee
shall  transmit  by mail to all  Certificateholders  notice  of such  occurrence
unless such default or Servicer Event of  Termination  shall have been waived or
cured. Such notice shall be given to the Certificate  Insurer promptly after any
such occurrence.

          Section 7.05 SURVIVABILITY OF SERVICER LIABILITIES.

          Notwithstanding  anything herein to the contrary,  upon termination of
the Master  Servicer  hereunder,  any  liabilities of the Master  Servicer which
accrued prior to such termination shall survive such termination.


                                  ARTICLE VIII

                                   THE TRUSTEE

          Section 8.01 DUTIES OF TRUSTEE.

          The  Trustee,   prior  to  the  occurrence  of  a  Servicer  Event  of
Termination and after the curing of all Servicer Events of Termination which may
have  occurred,  undertakes  to perform  such duties and only such duties as are
specifically set forth in this Agreement. If a Servicer Event of Termination has
occurred  (which  has not  been  cured)  of  which  a  Responsible  Officer  has
knowledge, 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 man would exercise or use under the circumstances in the conduct of
his own affairs.

          The   Trustee,   upon  receipt  of  all   resolutions,   certificates,
statements,  opinions, reports, documents, orders or other instruments furnished
to the Trustee which 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;  provided,  however,  that the
Trustee  will  not be  responsible  for the  accuracy  or  content  of any  such
resolutions,  certificates,  statements,  opinions,  reports, documents or other
instruments.  If any such instrument is found not to conform to the requirements
of this Agreement in a material  manner the Trustee shall take such action as it
deems appropriate to have the instrument corrected, and if the instrument is not
corrected to the Trustee's satisfaction, the Trustee will provide notice thereof
to the Certificate Insurer and will, at the expense of the Seller, which expense
shall be reasonable given the scope and nature of the required action, take such
further action as directed by the Certificate Insurer.

          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; PROVIDED, HOWEVER, that:

          (i) prior to the  occurrence of a Servicer Event of  Termination,  and
     after the curing of all such Servicer Events of Termination  which 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 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, in
     the  absence  of bad  faith on the part of the  Trustee,  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;

          (ii)  the  Trustee  shall  not be  personally  liable  for an error of
     judgment made in good faith by a Responsible Officer of the Trustee, unless
     it shall be proved  that the  Trustee  was  negligent  in  ascertaining  or
     investigating the facts related thereto;

          (iii) 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 the direction of the  Certificate  Insurer or in accordance
     with the direction of the Majority  Certificateholders (with the consent of
     the Certificate  Insurer, so long as no Certificate Insurer Default exists)
     relating to the time, method and place of conducting any proceeding for any
     remedy available to the Trustee,  or exercising or omitting to exercise any
     trust or power conferred upon the Trustee, under this Agreement; and

          (iv) the Trustee shall not be charged with knowledge of any failure by
     the Master  Servicer to comply with the  obligations of the Master Servicer
     referred to in clauses (i) and (ii) of Section 7.01(a) unless a Responsible
     Officer  of the  Trustee  at the  Corporate  Trust  Office  obtains  actual
     knowledge of such failure or the Trustee  receives  written  notice of such
     failure from the Master Servicer,  the Certificate Insurer, or the Majority
     Certificateholders.

          The  Trustee  shall not be required to expend or risk its own funds or
otherwise  incur  financial  liability in the  performance  of any of its duties
hereunder,  or in the  exercise  of any of its  rights  or  powers,  if there is
reasonable  ground for  believing  that the  repayment of such funds or adequate
indemnity  against such risk or liability is not  reasonably  assured to it, and
none of the provisions  contained in this  Agreement  shall in any event require
the Trustee to perform,  or be responsible for the manner of performance of, any
of the obligations of the Master  Servicer under this  Agreement,  except during
such time,  if any, as the Trustee shall be the successor to, and be vested with
the rights,  duties, powers and privileges of, the Master Servicer in accordance
with the terms of this Agreement.

          Section 8.02 CERTAIN MATTERS AFFECTING THE TRUSTEE.

          (a) Except as otherwise provided in Section 8.01:

          (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 or any other certificate,  statement,
     instrument,  opinion,  report, notice, request,  consent, order, appraisal,
     bond or other paper or document reasonably believed by it to be genuine and
     to have been signed or presented  by the proper  party or parties,  and the
     manner of obtaining  consents and of evidencing  the  authorization  of the
     execution thereof by Certificateholders shall be subject to such reasonable
     regulations as the Trustee may prescribe;

          (ii) the Trustee may consult  with  counsel and 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 Opinion of Counsel;

          (iii) the Trustee  shall be under no obligation to exercise any of the
     rights 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,  or the  Certificate
     Insurer,  pursuant  to  the  provisions  of  this  Agreement,  unless  such
     Certificateholders,  and the Certificate  Insurer shall have offered to the
     Trustee  reasonable  security or indemnity against the costs,  expenses and
     liabilities  which may be  incurred  therein or  thereby;  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 any
     such act;

          (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 a Servicer  Event of  Termination  and
     after the  curing of all  Servicer  Events  of  Termination  which 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 documents,  unless  requested in writing to do so by
     the Certificate Insurer or the Majority Certificateholder (with the consent
     of the  Certificate  Insurer,  so long as no  Certificate  Insurer  Default
     exists and is continuing);  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 cost, expense or liability as a condition
     to such proceeding.  The reasonable expense of every such examination shall
     be paid by the  Master  Servicer  or,  if paid  by the  Trustee,  shall  be
     reimbursed by the Master  Servicer upon demand.  Nothing in this clause (v)
     shall  derogate from the  obligation of the Master  Servicer to observe any
     applicable  law  prohibiting   disclosure  of  information   regarding  the
     Mortgagors;

          (vi) the Trustee shall not be accountable, shall have no liability and
     makes no representation as to any acts or omissions hereunder of the Master
     Servicer  until such time as the  Trustee  may be required to act as Master
     Servicer  pursuant  to  Section  7.02  and  thereupon  only for the acts or
     omissions of the Trustee as successor Servicer;

          (vii) 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 or a custodian; and

          (viii)  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.

          Section 8.03 TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.

          The recitals contained herein and in the Certificates  (other than the
authentication  of the  Trustee  on the  Certificates)  shall  be  taken  as the
statements  of the Seller,  and the Trustee  assumes no  responsibility  for the
correctness of the same. The Trustee makes no representations as to the validity
or  sufficiency  of  this  Agreement  or of the  Certificates  (other  than  the
signature  and  authentication  of the  Trustee on the  Certificates)  or of any
Mortgage Loan or related document.  The Trustee shall not be accountable for the
use or application by the Master Servicer,  or for the use or application of any
funds paid to the Master  Servicer in respect of the Mortgage Loans or deposited
in or withdrawn from the Collection Account by the Master Servicer.  The Trustee
shall at no time have any responsibility or liability for or with respect to the
legality,  validity and  enforceability of any Mortgage or any Mortgage Loan, or
the  perfection  and  priority of any  Mortgage or the  maintenance  of any such
perfection and priority,  or for or with respect to the sufficiency of the Trust
or its ability to generate the payments to be distributed to  Certificateholders
under this Agreement,  including,  without limitation: the existence,  condition
and ownership of any Mortgaged Property; the existence and enforceability of any
hazard  insurance  thereon (other than if the Trustee shall assume the duties of
the Master Servicer pursuant to Section 7.02); the validity of the assignment of
any  Mortgage  Loan  to  the  Trustee  or of  any  intervening  assignment;  the
completeness  of any  Mortgage  Loan;  the  performance  or  enforcement  of any
Mortgage  Loan (other than if the Trustee  shall assume the duties of the Master
Servicer pursuant to Section 7.02); the compliance by the Depositor,  the Seller
or the Master  Servicer  with any  warranty  or  representation  made under this
Agreement  or in any related  document or the  accuracy of any such  warranty or
representation  prior to the Trustee's  receipt of notice or other  discovery of
any non-compliance  therewith or any breach thereof; any investment of monies by
or at the direction of the Master Servicer or any loss resulting  therefrom,  it
being  understood  that the  Trustee  shall  remain  responsible  for any  Trust
property that it may hold in its individual  capacity;  the acts or omissions of
any of the Master Servicer (other than if the Trustee shall assume the duties of
the  Master  Servicer  pursuant  to  Section  7.02),  any  Sub-Servicer  or  any
Mortgagor;  any action of the Master  Servicer  (other than if the Trustee shall
assume the duties of the  Master  Servicer  pursuant  to Section  7.02),  or any
Sub-Servicer  taken  in the  name of the  Trustee;  the  failure  of the  Master
Servicer  or any  Sub-Servicer  to act or perform  any duties  required of it as
agent of the  Trustee  hereunder;  or any  action  by the  Trustee  taken at the
instruction of the Master  Servicer  (other than if the Trustee shall assume the
duties of the Master Servicer pursuant to Section 7.02); PROVIDED, HOWEVER, that
the  foregoing  shall not relieve the Trustee of its  obligation  to perform its
duties under this Agreement,  including,  without limitation, the Trustee's duty
to review the Mortgage Files pursuant to Section 2.01. 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 (unless the Trustee shall have
become the successor Servicer).

          Section 8.04 TRUSTEE MAY OWN CERTIFICATES.

          The Trustee 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  Trustee and may  transact  any  banking  and trust  business  with the
Seller, the Master Servicer, the Depositor or their Affiliates.

          Section 8.05 TRUSTEE'S FEES AND EXPENSES.

          The Trustee shall be entitled to the Trustee's Fee (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express  trust) for all  services  rendered by the Trustee in the  exercise  and
performance  of any of the  powers  and  duties  hereunder.  The  Trustee  shall
withdraw  from the  Distribution  Account on each  Distribution  Date and pay to
itself the Trustee's  Fee. The Seller will pay or reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made
by the  Trustee  in  accordance  with any of the  provisions  of this  Agreement
(including the reasonable compensation and the expenses and disbursements of its
counsel and of all persons not regularly in its employ) except any such expense,
disbursement  or advance as may arise from its  negligence or bad faith or which
is the  responsibility  of  Certificateholders  or  the  Trustee  hereunder.  In
addition,  the Seller  covenants  and agrees to  indemnify  the  Trustee and its
officers,  directors,  employees and agents from, and hold it harmless  against,
any and all  losses,  liabilities,  damages,  claims  or  expenses  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 negligence of the Trustee in the  performance  of its
duties hereunder or by reason of the Trustee's reckless disregard of obligations
and duties hereunder.  This section shall survive  termination of this Agreement
or the resignation or removal of any Trustee hereunder.

          Section 8.06 ELIGIBILITY REQUIREMENTS FOR TRUSTEE.

          The Trustee  hereunder  shall at all times be an entity duly organized
and validly existing under the laws of the United States of America or any state
thereof, authorized under such laws to exercise corporate trust powers, having a
combined  capital and surplus of at least  $50,000,000  and a minimum  long-term
debt rating of Baa3 by Moody's and a  short-term  rating of at least A-1 by S&P,
and subject to supervision or examination by federal or state authority. If such
entity 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  8.06,  the  combined  capital and surplus of such
entity  shall be deemed to be its  combined  capital and surplus as set forth in
its most recent  report of condition so published.  The principal  office of the
Trustee  (other than the initial  Trustee)  shall be in a state with  respect to
which an Opinion of Counsel has been  delivered to such Trustee at the time such
Trustee is appointed  Trustee to the effect that the Trust will not be a taxable
entity under the laws of such state. In case at any time the Trustee shall cease
to be eligible in  accordance  with the  provisions  of this Section  8.06,  the
Trustee shall resign  immediately in the manner and with the effect specified in
Section 8.07.

          Section 8.07 RESIGNATION OR REMOVAL OF TRUSTEE.

          The Trustee may at any time resign and be  discharged  from the trusts
hereby created by giving  written  notice  thereof to the Depositor,  the Master
Servicer,  the Certificate  Insurer and each Rating Agency.  Upon receiving such
notice of resignation,  the Depositor shall promptly appoint a successor Trustee
(approved in writing by the Certificate  Insurer, so long as such approval shall
not be unreasonably withheld) by written instrument,  in duplicate,  one copy of
which instrument shall be delivered to the resigning Trustee and one copy to the
successor  Trustee.  If no successor  Trustee  shall have been so appointed  and
having  accepted  appointment  within 30 days after the giving of such notice of
resignation,   the  resigning  Trustee  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor Trustee.

          If at any time the Trustee  shall  cease to be eligible in  accordance
with the  provisions  of  Section  8.06 and shall fail to resign  after  written
request therefor by the Certificate  Insurer of the Depositor,  with the consent
of the Certificate Insurer (so long as no Certificate Insurer Default exists) or
if at any time the Trustee shall be legally  unable to act, 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,  then the Depositor, the Certificate Insurer or the Master Servicer
may remove the  Trustee.  If the  Depositor,  Certificate  Insurer or the Master
Servicer  removes the Trustee under the authority of the  immediately  preceding
sentence,  the Depositor shall promptly appoint a successor Trustee (approved in
writing by the Certificate Insurer, so long as such approval is not unreasonably
withheld) by written  instrument,  in  duplicate,  one copy of which  instrument
shall be  delivered  to the  Trustee  so removed  and one copy to the  successor
trustee.

          The Majority Certificateholders may, with the prior written consent of
the Certificate Insurer (so long as no Certificate Insurer Default exists and is
continuing), at any time remove the Trustee by written instrument or instruments
delivered to the Master Servicer,  the Depositor and the Trustee;  the Depositor
shall  thereupon  use its  best  efforts  to  appoint  a  successor  trustee  in
accordance with this Section.

          Any  resignation  or  removal  of the  Trustee  and  appointment  of a
successor  Trustee  pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor Trustee as
provided in Section 8.08.

          Notwithstanding  anything to the contrary contained herein, so long as
no Certificate  Insurer  Default  exists,  the Trustee may not be removed by the
Depositor or the  Certificateholders  without the prior  written  consent of the
Certificate Insurer, which consent shall not be unreasonably withheld.

          Section 8.08 SUCCESSOR TRUSTEE.

          Any  successor  Trustee  appointed  as provided in Section  8.07 shall
execute,  acknowledge and deliver to the Depositor, the Certificate Insurer, the
Master  Servicer 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 like
effect as if originally named as Trustee. The Depositor, the Master Servicer and
the predecessor  Trustee shall execute and deliver such  instruments and do such
other things as may  reasonably be required for 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 8.08 unless at the time of such acceptance such successor  Trustee shall
be eligible  under the  provisions of Section 8.06 and the  appointment  of such
successor Trustee shall not result in a downgrading of the Regular  Certificates
by either Rating Agency, as evidenced by a letter from each Rating Agency.

          Upon  acceptance of appointment by a successor  Trustee as provided in
this Section 8.08, the successor Trustee shall mail notice of the appointment of
a successor  Trustee hereunder to all Holders of Certificates at their addresses
as shown in the Certificate Register and to each Rating Agency.

          Notwithstanding  anything to the contrary contained herein, so long as
no Certificate  Insurer Default exists, the appointment of any successor Trustee
pursuant to any provision of this Agreement will be subject to the prior written
consent of the  Certificate  Insurer,  which consent  shall not be  unreasonably
withheld.

          Section 8.09 MERGER OR CONSOLIDATION OF TRUSTEE.

          Any entity into which the Trustee may be merged or  converted  or with
which  it  may be  consolidated,  or  any  entity  resulting  from  any  merger,
conversion or consolidation to which the Trustee shall be a party, or any entity
succeeding to the business of the Trustee, shall be the successor of the Trustee
hereunder,  provided  such entity  shall be  eligible  under the  provisions  of
Section  8.06 and  8.08,  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.

          Section 8.10 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 or any Mortgaged Property may at the time be located,  the
Depositor 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 and the Certificate Insurer 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,  and to vest in such Person or Persons,  in such  capacity and for
the  benefit of the  Certificateholders,  such  title to the Trust,  or any part
thereof, and, subject to the other provisions of this Section 8.10, such powers,
duties,  obligations,  rights and trusts as the Master  Servicer and the Trustee
may consider  necessary or desirable.  Any such  co-trustee or separate  trustee
shall  be  subject  to the  written  approval  of the  Master  Servicer  and the
Certificate  Insurer (so long as no  Certificate  Insurer  Default exists and is
continuing).  If the Master Servicer and the Certificate  Insurer shall not have
joined in such  appointment  within 15 days after the receipt by it of a request
so to do, or in the case a Servicer Event of Termination 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  8.06,  and no notice to
Certificateholders  of the  appointment  of any  co-trustee or separate  trustee
shall be required under Section 8.08.  The Master  Servicer shall be responsible
for the fees of any co-trustee or separate trustee appointed hereunder.

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

          (i) all rights,  powers,  duties and obligations  conferred or imposed
     upon the  Trustee  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 (whether as Trustee hereunder or
     as  successor  to the Master  Servicer  hereunder),  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  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;

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

          (iii) the Master  Servicer  and the  Trustee,  with the consent of the
     Certificate  Insurer (so long as no Certificate  Insurer Default exists and
     is continuing), acting jointly may at any time accept the resignation of or
     remove any  separate  trustee  or  co-trustee  except  that  following  the
     occurrence of a Servicer Event of Termination, the Trustee acting alone may
     accept the resignation 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 VIII. 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
Depositor, the Certificate Insurer and the Master Servicer.

          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.  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 8.11 LIMITATION OF LIABILITY.

          The  Certificates  are executed by the Trustee,  not in its individual
capacity  but solely as Trustee of the Trust,  in the exercise of the powers and
authority  conferred  and  vested  in it by the  Trust  Agreement.  Each  of the
undertakings  and agreements made on the part of the Trustee in the Certificates
is made and intended not as a personal  undertaking  or agreement by the Trustee
but is made and intended for the purpose of binding only the Trust.

          Section  8.12  TRUSTEE  MAY  ENFORCE  CLAIMS  WITHOUT   POSSESSION  OF
CERTIFICATES.

          (a) All  rights of action  and  claims  under  this  Agreement  or the
Certificates  may  be  prosecuted  and  enforced  by  the  Trustee  without  the
possession  of  any  of  the  Certificates  or  the  production  thereof  in any
proceeding relating thereto, and such proceeding instituted by the Trustee shall
be brought in its own name or in its  capacity as Trustee for the benefit of all
Holders of such Certificates,  subject to the provisions of this Agreement.  Any
recovery of judgment  shall,  after  provision for the payment of the reasonable
compensation, expenses, disbursement and advances of the Trustee, its agents and
counsel,  be  for  the  ratable  benefit  or  the   Certificateholders  and  the
Certificate Insurer in respect of which such judgment has been recovered.

          (b) The Trustee  shall afford the Seller,  the  Depositor,  the Master
Servicer,  the Certificate Insurer, and each  Certificateholder  upon reasonable
notice during normal  business  hours,  access to all records  maintained by the
Trustee in respect of its duties hereunder and access to officers of the Trustee
responsible for performing such duties. Upon request,  the Trustee shall furnish
the Depositor,  the Master Servicer,  the Certificate Insurer and any requesting
Certificateholder  with its most recent financial statements.  The Trustee shall
cooperate  fully  with the  Seller,  the Master  Servicer,  the  Depositor,  the
Certificate Insurer, and such  Certificateholder and shall make available to the
Seller, the Master Servicer,  the Depositor,  the Certificate  Insurer, and such
Certificateholder for review and copying such books, documents or records as may
be requested with respect to the Trustee's  duties  hereunder.  The Seller,  the
Depositor,   the   Master   Servicer,   the   Certificate   Insurer,   and   the
Certificateholders shall not have any responsibility or liability for any action
or  failure  to act by the  Trustee  and  are not  obligated  to  supervise  the
performance of the Trustee under this Agreement or otherwise.

          Section 8.13 SUITS FOR ENFORCEMENT.

          In case a Servicer Event of Termination or other default by the Master
Servicer or the Depositor hereunder shall occur and be continuing,  the Trustee,
shall, at the direction of the Certificate  Insurer, or may, with the consent of
the Certificate  Insurer,  may proceed to protect and enforce its rights and the
rights of the Certificateholders or the Certificate Insurer under this Agreement
by a suit,  action or proceeding  in equity or at law or otherwise,  whether for
the  specific  performance  of any  covenant  or  agreement  contained  in  this
Agreement or in aid of the execution of any power  granted in this  Agreement or
for the  enforcement  of any other  legal,  equitable  or other  remedy,  as the
Trustee, being advised by counsel, and subject to the foregoing, shall deem most
effectual  to  protect  and  enforce  any of the  rights  of  the  Trustee,  the
Certificate Insurer and the Certificateholders.

          Section 8.14 WAIVER OF BOND REQUIREMENT.

          The Trustee  shall be relieved of, and each  Certificateholder  hereby
waives,  any  requirement of any  jurisdiction  in which the Trust,  or any part
thereof,  may be located  that the Trustee  post a bond or other surety with any
court, agency or body whatsoever.

          Section   8.15  WAIVER  OF   INVENTORY,   ACCOUNTING   AND   APPRAISAL
REQUIREMENT.

          The Trustee  shall be relieved of, and each  Certificateholder  hereby
waives,  any  requirement of any  jurisdiction  in which the Trust,  or any part
thereof,  may be located  that the Trustee  file any  inventory,  accounting  or
appraisal  of the  Trust  with any  court,  agency or body at any time or in any
manner whatsoever.


                                   ARTICLE IX

                              REMIC ADMINISTRATION

          Section 9.01 REMIC ADMINISTRATION.

          (a) REMIC elections as set forth in the Preliminary Statement shall be
made by the Trustee on Form 1066 or other appropriate federal tax or information
return for the taxable year ending on the last day of the calendar year in which
the Certificates are issued. The regular interests and residual interest in each
REMIC shall be as designated in the Preliminary Statement.

          (b) The Closing Date is hereby designated as the "Startup Day" of each
REMIC within the meaning of section 860G(a)(9) of the Code. The "latest possible
maturity  date" of the regular  interests  of each REMIC,  within the meaning of
Treasury Regulation Section 1.860G-1(a)(4)(iii) will be October 25, 2029.

          (c) The Master  Servicer  shall pay any and all tax  related  expenses
(not  including  taxes,  except as provided  in Section  9.01(l)) of each REMIC,
including but not limited to any professional fees or expenses related to audits
or any  administrative  or judicial  proceedings  with respect to any REMIC that
involve the Internal Revenue Service or state tax  authorities,  but only to the
extent  that (i) such  expenses  are  ordinary  or routine  expenses,  including
expenses of a routine audit but not expenses of litigation  (except as described
in (ii)); or (ii) such expenses or liabilities  (including  taxes and penalties)
are attributable to the negligence or willful  misconduct of the Master Servicer
in  fulfilling  its  duties  hereunder  (including  its  duties  as  tax  return
preparer). The Master Servicer shall be entitled to reimbursement of expenses to
the extent provided in clause (i) above from the Collection Account.

          (d) The Trustee shall prepare or cause to be prepared, and the Trustee
shall sign and file or cause to be filed,  all of the REMICs'  federal and state
tax and information returns as each REMIC's direct representative.  The expenses
of preparing and filing such returns shall be borne by the Trustee.

          (e) The  Holder of the Class R  Certificate  at any time  holding  the
largest Percentage Interest thereof shall be the "tax matters person" as defined
in the REMIC  Provisions  (the "Tax Matters  Person") with respect to each REMIC
and shall act as Tax Matters  Person for each REMIC.  The Trustee,  as agent for
the Tax Matters Person,  shall perform on behalf of each REMIC all reporting and
other tax  compliance  duties that are the  responsibility  of a REMIC under the
Code, the REMIC Provisions,  or other compliance guidance issued by the Internal
Revenue Service or any state or local taxing authority.  Among its other duties,
if required  by the Code,  the REMIC  Provisions,  or other such  guidance,  the
Trustee, as agent for the Tax Matters Person,  shall provide (i) to the Internal
Revenue Service or other governmental authority such information as is necessary
for  the  application  of  any  tax  relating  to  the  transfer  of a  Residual
Certificate  to  any  disqualified  person  or  organization  and  (ii)  to  the
Certificateholders  such  information  or reports as are required by the Code or
REMIC Provisions.

          (f) The Trustee,  the Master  Servicer and the Holders of Certificates
shall take any action or cause each REMIC to take any action necessary to create
or maintain the status of each REMIC as a REMIC under each REMIC  Provisions and
shall assist each other as necessary to create or maintain such status.  Neither
the Trustee,  the Master  Servicer  nor the Holder of any  Residual  Certificate
shall  take any  action,  cause any REMIC to take any action or fail to take (or
fail to cause to be taken) any action that, under any REMIC Provisions, if taken
or not taken,  as the case may be, could (i) endanger the status of any REMIC as
a REMIC or (ii) result in the imposition of a tax upon any 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 on Section 860G(d)
of the Code) (either such event,  an "Adverse  REMIC Event")  unless the Trustee
and the Master  Servicer  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.
In addition,  prior to taking any action with respect to any REMIC or the assets
therein, or causing such REMIC to take any action, which not expressly permitted
under the terms of this  Agreement,  any Holder of a Residual  Certificate  will
consult with the Trustee and the Master Servicer, or their respective designees,
in writing,  with respect to whether  such action  could cause an Adverse  REMIC
Event to occur with  respect to such REMIC,  and no such  Person  shall take any
such  action or cause any REMIC to take any such  action as to which the Trustee
or the Master  Servicer  has advised it in writing  that an Adverse  REMIC Event
could occur.

          (g) Subject to Section  9.03,  each  Holder of a Residual  Certificate
shall pay when due any and all taxes  imposed  on any REMIC by  federal or state
governmental authorities.  To the extent that such Trust taxes are not paid by a
Residual Certificateholder,  the Trustee shall pay any remaining REMIC taxes out
of  current  or future  amounts  otherwise  distributable  to the  Holder of the
Residual Certificate in such REMIC or, if no such amounts are available,  out of
other  amounts  held in the  Distribution  Account,  and  shall  reduce  amounts
otherwise payable to Holders of regular interests in such REMIC, as the case may
be.

          (h) The  Trustee,  as agent for the Tax  Matters  Person,  shall,  for
federal  income tax  purposes,  maintain  books and records with respect to each
REMIC on a calendar year and on an accrual basis.

          (i) No additional  contributions of assets shall be made to any REMIC,
except  as  expressly  provided  in this  Agreement  with  respect  to  eligible
substitute mortgage loans.

          (j) Neither the Trustee nor the Master  Servicer  shall enter into any
arrangement  by which any REMIC  will  receive a fee or other  compensation  for
services.

          (k) On or before April 15 of each calendar year beginning in 2000, the
Master Servicer shall deliver to the Trustee and each Rating Agency an Officer's
Certificate stating the Master Servicer's compliance with the provisions of this
Section 9.01.

          (l) The Master  Servicer shall pay annually as an expense of the Trust
Fund, without right of reimbursement  therefor, the annual minimum franchise tax
imposed on the REMICs by Sections 23153 and 24874 of the California  Revenue and
Taxation Code.

          Section 9.02 PROHIBITED TRANSACTIONS AND ACTIVITIES.

          Neither the Depositor, the Master Servicer nor the Trustee shall sell,
dispose of, or substitute for any of the Mortgage Loans, except in a disposition
pursuant to (i) the  foreclosure of a Mortgage Loan,  (ii) the bankruptcy of the
Trust Fund,  (iii) the  termination of the REMICs  pursuant to Article X of this
Agreement, (iv) a substitution pursuant to Article II of this Agreement or (v) a
repurchase  of  Mortgage  Loans  pursuant to Article II of this  Agreement,  nor
acquire any assets for any REMIC,  nor sell or dispose of any investments in the
Distribution  Account for gain, nor accept any  contributions to any REMIC after
the Closing  Date,  unless it has received an Opinion of Counsel (at the expense
of the  party  causing  such  sale,  disposition,  or  substitution)  that  such
disposition,  acquisition,  substitution,  or  acceptance  will  not (a)  affect
adversely the status of such REMIC as a REMIC or of the interests  therein other
than the Residual  Certificates as the regular interests therein, (b) affect the
distribution  of interest or  principal on the  Certificates,  (c) result in the
encumbrance  of the assets  transferred  or assigned  to the Trust Fund  (except
pursuant  to the  provisions  of this  Agreement)  or (d)  cause any REMIC to be
subject to a tax on prohibited transactions or prohibited contributions pursuant
to the REMIC Provisions.

          Section 9.03 INDEMNIFICATION WITH RESPECT TO CERTAIN TAXES AND LOSS OF
REMIC STATUS.

          In the event that any REMIC  fails to  qualify  as a REMIC,  loses its
status as a REMIC,  or  incurs  federal,  state or local  taxes as a result of a
prohibited transaction or prohibited contribution under the REMIC Provisions due
to  the  negligent  performance  by  the  Master  Servicer  of  its  duties  and
obligations set forth herein,  the Master Servicer shall indemnify the Holder of
the  Residual  Certificate  against  any  and  all  losses,   claims,   damages,
liabilities or expenses  ("Losses")  resulting from such  negligence;  provided,
however,  that the  Master  Servicer  shall  not be liable  for any such  Losses
attributable  to the action or inaction of the  Trustee,  the  Depositor  or the
Holder of such  Residual  Certificate,  as  applicable,  nor for any such Losses
resulting  from   misinformation   provided  by  the  Holder  of  such  Residual
Certificate on which the Master Servicer has relied.  The foregoing shall not be
deemed to limit or  restrict  the  rights  and  remedies  of the  Holder of such
Residual   Certificate   now  or  hereafter   existing  at  law  or  in  equity.
Notwithstanding  the foregoing,  however,  in no event shall the Master Servicer
have any  liability  (1) for any action or omission  that is taken in accordance
with and in  compliance  with  the  express  terms  of,  or  which is  expressly
permitted by the terms of, this Agreement, (2) for any Losses other than arising
out of a  negligent  performance  by the  Master  Servicer  of  its  duties  and
obligations set forth herein,  and (3) for any special or consequential  damages
to  Certificateholders  (in addition to payment of principal and interest on the
Certificates).

          Section 9.04 REO PROPERTY.

          (a) Notwithstanding any other provision of this Agreement,  the Master
Servicer,  acting on behalf of the Trustee  hereunder,  shall not, and shall, to
the  extent  provided  in the  applicable  Servicing  Agreement,  not permit any
Subservicer to, rent,  lease, or otherwise earn income on behalf of REMIC I with
respect to any REO  Property  which  might  cause such REO  Property  to fail to
qualify as  "foreclosure"  property within the meaning of section  860G(a)(8) of
the Code or result in the receipt by any REMIC of any "income from non-permitted
assets" within the meaning of section  860F(a)(2) of the Code or any "net income
from  foreclosure  property" which is subject to tax under the REMIC  Provisions
unless the Master Servicer has advised, or has caused the applicable Servicer to
advise,  the Trustee in writing to the effect that, under the REMIC  Provisions,
such action  would not  adversely  affect the status of any REMIC as a REMIC and
any income  generated for such REMIC by the REO Property would not result in the
imposition of a tax upon such REMIC.

          (b) The  Master  Servicer  shall  make,  or shall  cause  the  Special
Servicer  to make,  reasonable  efforts  to sell any REO  Property  for its fair
market value. In any event,  however,  the Master Servicer shall, or shall cause
the Special  Servicer to,  dispose of any REO  Property  before the close of the
third calendar year beginning after its acquisition by the Trust Fund unless the
Master Servicer or Special Servicer, as applicable,  on behalf of the Trust Fund
has  received a grant of  extension  from the  Internal  Revenue  Service to the
effect that, under the REMIC Provisions,  such REMIC may hold REO Property for a
longer  period  without  adversely  affecting  the REMIC  status of any REMIC or
causing the imposition of a Federal or state tax upon such REMIC.  If the Master
Servicer has received  such an extension,  then the Master  Servicer  shall,  or
shall  cause the  Special  Servicer  to,  continue  to  attempt  to sell the REO
Property  for its fair market  value for such period as such  extension  permits
(the  "Extended  Period").  If the  Master  Servicer  has not  received  such an
extension and the Master Servicer or the Special  Servicer is unable to sell the
REO  Property  before  September  30  of  the  third  calendar  year  after  its
acquisition  by the Trust Fund or if the Master  Servicer has  received  such an
extension, and the Master Servicer is unable to sell the REO Property within the
period ending three months before the close of the Extended  Period,  the Master
Servicer  shall,  or shall cause the Special  Servicer to, before the end of the
applicable  period,  (i) purchase  such REO Property at a price equal to the REO
Property's  fair market  value or (ii)  auction the REO  Property to the highest
bidder (which may be the Master Servicer or the Special  Servicer) in an auction
reasonably  designed  to produce a fair  price  prior to the  expiration  of the
applicable period.


                                    ARTICLE X

                                   TERMINATION

          Section 10.01 TERMINATION.

          (a) The respective obligations and responsibilities of the Seller, the
Master  Servicer,  the Depositor and the Trustee  created hereby (other than the
obligation of the Trustee to make certain payments to  Certificateholders  after
the final  Distribution  Date and the obligation of the Master  Servicer to send
certain  notices as  hereinafter  set forth) shall  terminate upon notice to the
Trustee  upon the later of (A) the payment in full of all  amounts  owing to the
Certificate  Insurer unless the Certificate  Insurer shall otherwise consent and
(B) the earliest of (i) the Distribution Date on which the Certificate Principal
Balance of each Class of Class A Certificates has been reduced to zero, (ii) the
final payment or other liquidation of the last Mortgage Loan in the Trust, (iii)
the optional  purchase by the Master Servicer or the Certificate  Insurer of the
Mortgage  Loans as  described  below and (iv) the  Distribution  Date in October
2029.  Notwithstanding the foregoing, in no event shall the trust created hereby
continue  beyond the  expiration of 21 years from the death of the last survivor
of the  descendants  of Joseph P.  Kennedy,  the late  ambassador  of the United
States to the Court of St. James's, living on the date hereof.

          The Master  Servicer or, if such option is not exercised by the Master
Servicer,  the Certificate Insurer may, at its option,  terminate this Agreement
on any date on which the  aggregate  of the  Principal  Balances of the Mortgage
Loans on such date is equal to or less than 10% of the  aggregate of the Cut-off
Date  Principal  Balance  of the  Mortgage  Loans,  by  purchasing,  on the next
succeeding  Distribution  Date,  all of the  outstanding  Mortgage Loans and REO
Properties  at a price  equal  to the sum of the  outstanding  Stated  Principal
Balance of the  Mortgage  Loans and accrued and unpaid  interest  thereon at the
weighted  average  of the  Mortgage  Rates  through  the end of the  Due  Period
preceding the final Distribution Date plus unreimbursed  Servicing Advances; any
amount owed the Certificate  Insurer under the Insurance  Agreement,  any unpaid
Servicing  Fees  allocable to such Mortgage  Loans and REO  Properties,  and any
accrued and unpaid Interest Carryover (the "Termination Price").

          In  connection  with  any  such  purchase  pursuant  to the  preceding
paragraph,  the Master  Servicer shall deposit in the  Distribution  Account all
amounts then on deposit in the Collection Account, which deposit shall be deemed
to have occurred immediately preceding such purchase.

          Any  such  purchase  shall  be   accomplished   by  deposit  into  the
Distribution  Account on the Determination Date before such Distribution Date of
the  Termination  Price.  The Master  Servicer shall  indemnify the  Certificate
Insurer for any claims under the Certificate  Insurance Policy due to the Master
Servicer's exercise of such option.

          (b) Notice of any termination, specifying the Distribution Date (which
shall be a date that  would  otherwise  be a  Distribution  Date) upon which the
Certificateholders  may surrender their  Certificates to the Trustee for payment
of the final  distribution  and  cancellation,  shall be given  promptly  by the
Trustee upon the Trustee receiving notice of such date from the Master Servicer,
by letter to the  Certificate  Insurer  and the  Certificateholders  mailed  not
earlier  than  the  15th  day and not  later  than  the  25th  day of the  month
immediately  preceding the month of such final  distribution  specifying (1) the
Distribution Date upon which final distribution of the Certificates will be made
upon  presentation and surrender of such Certificates at the office or agency of
the Trustee therein  designated,  (2) the amount of any such final  distribution
and (3) that the Record Date otherwise  applicable to such  Distribution Date is
not applicable, distributions being made only upon presentation and surrender of
the Certificates at the office or agency of the Trustee therein specified.

          (c) Upon presentation and surrender of the  Certificates,  the Trustee
shall  cause  to be  distributed  to  the  Holders  of the  Certificates  on the
Distribution Date for such final  distribution,  in proportion to the Percentage
Interests of their  respective  Class and to the extent that funds are available
for such purpose,  an amount equal to the amount  required to be  distributed to
such  Holders  in  accordance  with  the  provisions  of  Section  4.01 for such
Distribution Date. Such funds available for distribution shall be deemed to have
been distributed in final payment of the REMIC I Regular Interests and the REMIC
II Regular  Interests in accordance  with Section 4.02, and any remaining  funds
shall be distributed  to the holders of the Class R  Certificates  in respect of
the related  REMIC.  On the final  Distribution  Date, the Trustee will withdraw
from the Distribution Account and remit to the Certificate Insurer the lesser of
(x) the amount available for distribution on such final  Distribution  Date, net
of any portion thereof necessary to pay holders of Class A Certificates pursuant
to Section 4.01 and due and unpaid Monthly  Advances and Servicing Fees, (y) the
unpaid amounts due and owing to the Certificate Insurer pursuant to Section 4.01
and the Insurance Agreement.

          (d) In the event that all Certificateholders shall not surrender their
Certificates  for  final  payment  and  cancellation  on or  before  such  final
Distribution  Date,  the Trustee shall  promptly  following  such date cause all
funds in the  Distribution  Account not  distributed  in final  distribution  to
Certificateholders  to be  withdrawn  therefrom  and  credited to the  remaining
Certificateholders  by depositing such funds in a separate Servicing Account for
the benefit of such  Certificateholders,  and the Master Servicer (if the Master
Servicer has exercised its right to purchase the Mortgage  Loans) or the Trustee
(in any  other  case)  shall  give a  second  written  notice  to the  remaining
Certificateholders, to surrender their Certificates for cancellation and receive
the final  distribution  with respect  thereto.  If within nine months after the
second  notice  all  the  Certificates  shall  not  have  been  surrendered  for
cancellation,  the Class R Certificateholders shall be entitled to all unclaimed
funds and other  assets  which  remain  subject  hereto,  and the  Trustee  upon
transfer of such funds shall be discharged of any responsibility for such funds,
and the  Certificateholders  shall  look to the Class R  Certificateholders  for
payment.

          Section 10.02 ADDITIONAL TERMINATION REQUIREMENTS.

          (a) In the event that the  Certificate  Insurer or the Master Servicer
exercises its purchase  option as provided in Section 10.01,  the Trust shall be
terminated in accordance with the following additional requirements,  unless the
Trustee shall have been  furnished with an Opinion of Counsel to the effect that
the failure of the Trust to comply with the  requirements  of this  Section will
not (i) result in the  imposition of taxes on "prohibited  transactions"  of the
Trust  as  defined  in  Section  860F  of the  Code  or  (ii)  cause  any  REMIC
constituting  part of the Trust  Fund to fail to  qualify as a REMIC at any time
that any Certificates are outstanding:

          (i) On the final tax return of each REMIC, the Trustee shall designate
     a date which is within 90 days prior to the final  Distribution Date as the
     date of  adoption  of a plan of  complete  liquidation  of each REMIC under
     Section 860F of the Code and any regulations thereunder;

          (ii) On or  after  the  date of  adoption  of such a plan of  complete
     liquidation  and at or prior to the final  Distribution  Date,  the Trustee
     shall  sell  all of the  assets  of the  Trust  to  the  Majority  Class  R
     Certificateholder or the Master Servicer, as applicable,  for cash pursuant
     to the terms of the plan of complete liquidation; and

          (iii)  At  the  time  of  the  making  of  the  final  payment  on the

     Certificates,  the related Class Certificate  Principal  Balance,  plus one
     month's interest thereon at the applicable Pass-Through Rate and (B) to the
     Certificate  Insurer,  all amounts owing to the  Certificate  Insurer under
     this Agreement and the Insurance Agreement and the Trust shall terminate at
     such time.

          (b) By their  acceptance of  Certificates,  the Holders thereof hereby
agree to appoint the Trustee as their attorney in fact to: (i) adopt such a plan
of  complete  liquidation  as  appropriate  or upon the  written  request of the

as may be reasonably required to carry out such plan of complete liquidation all
in accordance with the terms hereof.

CLASS A CERTIFICATEHOLDERS.

          Each of the  Depositor,  the Master  Servicer,  the  Trustee,  and, by
accepting its Certificate, each Class A Certificateholder, agrees that unless an
Certificate  Insurer  Default has occurred and is  continuing,  the  Certificate
Insurer   shall  have  the  right  to  exercise   all  rights  of  the  Class  A
Certificateholders under this Agreement (except as provided in clause (i) of the
second  paragraph of Section 12.01)  without any further  consent of the Class A
Certificateholders, including, without limitation:

          (a) the right to require the Seller to repurchase  or  substitute  for

          (b) the right to give notices of breach or to terminate the rights and
obligations of the Master Servicer pursuant to Section 7.01;

          In addition,  each Class A  Certificateholder  agrees that,  unless an
Certificate  Insurer  Default  has  occurred  and  is  continuing,   the  rights
specifically set forth above may be exercised by the Class A  Certificateholders
only with the prior written consent of the Certificate Insurer.

          Section  11.02  TRUSTEE TO ACT SOLELY WITH CONSENT OF THE  CERTIFICATE
INSURER.

          Unless an Certificate  Insurer Default has occurred and is continuing,
the Trustee shall not:

          (a) agree to any amendment pursuant to Section 12.01; or

          (b) undertake any litigation pursuant to Section 8.02(a)(iii);

without the prior written consent of the Certificate Insurer which consent shall
not be unreasonably withheld.

          Section  11.03  TRUST  FUND  AND  ACCOUNTS  HELD  FOR  BENEFIT  OF THE
CERTIFICATE INSURER.

          The Trustee  shall hold the Trust Fund and the Mortgage  Files for the
benefit of the Certificateholders and the Certificate Insurer and all references
in this Agreement (including, without limitation, in Sections 2.01 and 2.02) and
in the  Certificates  to the  benefit of Holders  of the  Certificates  shall be
deemed to include the  Certificate  Insurer.  The Trustee shall cooperate in all
reasonable  respects with any reasonable request by the Certificate  Insurer for
action to preserve  or enforce the  Certificate  Insurer's  rights or  interests
under this Agreement and the Certificates.

          The Master  Servicer  hereby  acknowledges  and  agrees  that it shall
service and  administer  the Mortgage  Loans and any REO  Properties,  and shall
maintain the  Accounts,  for the benefit of the  Certificateholders  and for the
benefit  of the  Certificate  Insurer,  and all  references  in  this  Agreement
(including, without limitation, in Section 3.01) to the benefit of or actions on
behalf of the  Certificateholders  shall be deemed to  include  the  Certificate
Insurer.  Unless an Certificate  Insurer Default has occurred and is continuing,
the Master Servicer shall not terminate any sub-servicing agreements without the
prior consent of the Certificate Insurer.  Unless an Certificate Insurer Default
has occurred and is  continuing,  neither the Master  Servicer nor the Depositor
shall  undertake any litigation  pursuant to Section 6.03 (other than litigation
to enforce their respective rights  hereunder)  without the prior consent of the
Certificate Insurer.

          Section   11.04  CLAIMS  UPON  THE   CERTIFICATE   INSURANCE   POLICY;
CERTIFICATE INSURANCE POLICY PAYMENTS ACCOUNT.

          (a) If, by the Close of Business on the third  Business Day prior to a
Distribution  Date,  the Trustee  determines  that a  Deficiency  Amount for any
Distribution  Date is  greater  than zero or that a claim may be made  under the
Certificate Insurance Policy in respect to any amount paid to Certificateholders
which is recoverable in bankruptcy as a preference,  then the Trustee shall give
notice to the Certificate Insurer by telephone or telecopy of the amount of such
Deficiency Amount or preference.  Such notice of such Deficiency Amount shall be
confirmed  in writing in the form set forth as Exhibit A to the  Endorsement  of
the Certificate  Insurance  Policy,  to the  Certificate  Insurer and the Fiscal
Agent (as defined in the  Certificate  Insurance  Policy),  if any, at or before
12:00 noon New York time on the second  Business Day prior to such  Distribution
Date. Following Receipt (as defined in the Certificate  Insurance Policy) by the
Certificate  Insurer of such notice in such form, the Certificate Insurer or the
Fiscal Agent will pay any amount payable under the Certificate  Insurance Policy
on the later to occur of (i) 12:00 noon New York time on the second Business Day
following  such  receipt  and (ii) 12:00 noon New York time on the  Distribution
Date to which such  deficiency  relates,  as provided in the  Endorsement to the
Certificate Insurance Policy.

          (b) The Trustee  shall  establish  a separate  special  purpose  trust
account  for  the  benefit  of  Holders  of the  Class  A  Certificates  and the
Certificate  Insurer  referred to herein as the  "Certificate  Insurance  Policy
Payments  Account" over which the Trustee shall have exclusive  control and sole
right of  withdrawal.  The  Trustee  shall  deposit  any  amount  paid under the
Certificate  Insurance  Policy  in the  Certificate  Insurance  Policy  Payments
Account and  distribute  such amount only for  purposes of payment to Holders of
Class A Certificates of the Insured Payment for which a claim was made, and such
amount may not be applied to satisfy any costs,  expenses or  liabilities of the
Master  Servicer,  the  Trustee  or the  Trust  Fund.  Amounts  paid  under  the
Certificate Insurance Policy shall be transferred to the Distribution Account in
accordance  with the next  succeeding  paragraph and disbursed by the Trustee to
Holders of Class A Certificates  in accordance  with Section  4.01(c) or Section
10.01, as applicable.  It shall not be necessary for such payments to be made by
checks or wire transfers  separate from the checks or wire transfers used to pay
the Insured  Payment with other funds  available to make such payment.  However,
the  amount  of  any  payment  of  principal  of or  interest  on  the  Class  A
Certificates to be paid from funds  transferred  from the Certificate  Insurance
Policy Payments Account shall be noted as provided in paragraph (c) below in the
Certificate  Register  and in the  statement  to be  furnished to Holders of the
Class A  Certificates  pursuant to Section 4.02.  Funds held in the  Certificate
Insurance Policy Payments Account shall not be invested.

          On any  Distribution  Date with respect to which a claim has been made
under the Certificate  Insurance Policy, the amount of any funds received by the
Trustee as a result of any claim under the Certificate  Insurance Policy, to the
extent required to make the Insured Payment on such Distribution  Date, shall be
withdrawn from the Certificate  Insurance  Policy Payments Account and deposited
in the Distribution Account and applied by the Trustee,  together with the other
funds to be withdrawn from the Distribution  Account pursuant to Section 4.01(c)
or Section 10.01, as applicable,  directly to the payment in full of the Insured
Payment  due on the Class A  Certificates.  Funds  received  by the Trustee as a
result of any claim under the Certificate Insurance Policy shall be deposited by
the Trustee in the Certificate Insurance Policy Payments Account and used solely
for payment to the Holders of the Class A Certificates and may not be applied to
satisfy any costs, expenses or liabilities of the Master Servicer,  the Trustee,
or the Trust Fund.  Any funds  remaining  in the  Certificate  Insurance  Policy
Payments  Account on the first Business Day following a Distribution  Date shall
be remitted to the  Certificate  Insurer,  pursuant to the  instructions  of the
Certificate Insurer, by the end of such Business Day.

          (c) The  Trustee  shall keep a  complete  and  accurate  record of the
amount of interest and principal paid in respect of any Class A Certificate from
moneys received under the Certificate  Insurance Policy. The Certificate Insurer
shall have the right to inspect such records at  reasonable  times during normal
business hours upon one Business Day's prior notice to the Trustee.

          (d) The Trustee  shall  promptly  notify the  Certificate  Insurer and
Fiscal Agent of any  proceeding  or the  institution  of any action,  of which a
Responsible Officer of the Trustee has actual knowledge seeking the avoidance as
a preferential transfer under applicable bankruptcy, insolvency, receivership or
similar law (a "Preference  Claim") of any Insured  Payment made with respect to
the  Class A  Certificates.  Each  Holder of the  Class A  Certificates,  by its
purchase of such Certificates, the Master Servicer, and the Trustee hereby agree
that the  Certificate  Insurer (so long as no  Certificate  Insurer  Default has
occurred  and is  continuing)  may at any time  during the  continuation  of any
proceeding  relating to a Preference  Claim direct all matters  relating to such
Preference Claim, including, without limitation, (i) the direction of any appeal
of any order  relating  to such  Preference  Claim and (ii) the  posting  of any
surety, supersedeas or performance bond pending any such appeal. In addition and
without limitation of the foregoing, the Certificate Insurer shall be subrogated
to the rights of the Master Servicer,  the Trustee, and each Holder of the Class
A Certificates in the conduct of any such Preference Claim,  including,  without
limitation,  all  rights of any party to an  adversary  proceeding  action  with
respect to any court order issued in connection with any such Preference Claim.

          Section  11.05  EFFECT  OF  PAYMENTS  BY  THE   CERTIFICATE   INSURER;
SUBROGATION.

          Anything  herein to the  contrary  notwithstanding,  any payment  with
respect to principal of or interest on any of the Class A Certificates  which is
made with moneys  received  pursuant to the terms of the  Certificate  Insurance
Policy shall not be  considered  payment of such Class A  Certificates  from the
Trust  Fund and shall not  result in the  payment  of or the  provision  for the
payment of the principal of or interest on such Certificates  within the meaning
of Section 4.01. The Depositor, the Master Servicer and the Trustee acknowledge,
and each Holder by its acceptance of a Class A Certificate  agrees, that without
the need for any  further  action on the part of the  Certificate  Insurer,  the
Depositor,  the Master Servicer or the Trustee (a) to the extent the Certificate
Insurer makes  payments,  directly or indirectly,  on account of principal of or
interest on any Class A Certificates  to the Holders of such  Certificates,  the
Certificate  Insurer will be fully  subrogated  to the rights of such Holders to
receive such principal and interest from the Trust Fund and (b) the  Certificate
Insurer shall be paid such  principal and interest but only from the sources and
in the manner provided herein for the payment of such principal and interest.

          The Trustee and the Master  Servicer  shall  cooperate in all respects
with any reasonable request by the Certificate Insurer for action to preserve or
enforce the  Certificate  Insurer's  rights or  interests  under this  Agreement
without  limiting  the  rights or  affecting  the  interests  of the  Holders as
otherwise set forth herein.

          Section 11.06 NOTICES TO THE CERTIFICATE INSURER.

          All notices, statements, reports, certificates or opinions required by
this Agreement to be sent to any other party hereto or to the Rating Agencies or
any of the Certificateholders shall also be sent to the Certificate Insurer.

          Section 11.07 THIRD-PARTY BENEFICIARY.

          The  Certificate  Insurer shall be a third-party  beneficiary  of this
Agreement, entitled to enforce the provisions hereof as if a party hereto.

          Section 11.08 TRUSTEE TO HOLD THE CERTIFICATE INSURANCE Policy.

          The Trustee  will hold the  Certificate  Insurance  Policy in trust as
agent for the  Holders  of the Class A  Certificates  for the  purpose of making
claims thereon and distributing the proceeds thereof.  Upon the later of (i) the
date upon  which the  aggregate  Certificate  Principal  Balance  of the Class A
Certificates  has been reduced to zero and all Insured  Payments  have been made
and (ii) the date the Term of the  Certificate  Insurance  Policy (as defined in
the  Certificate  Insurance  Policy)  ends,  the Trustee,  shall  surrender  the
Certificate  Insurance Policy to the Certificate Insurer for cancellation.  Each
Holder of Class A  Certificates,  by accepting  its  Certificates,  appoints the
Trustee as attorney-in-fact  for the purpose of making claims on the Certificate
Insurance Policy.


                                   ARTICLE XII

                            MISCELLANEOUS PROVISIONS

          Section 12.01 AMENDMENT.

          This  Agreement  may be  amended  from  time to time  by  Seller,  the
Depositor,  the Master  Servicer,  the Special  Servicer  and the  Trustee;  and
without the consent of the Certificateholders,  but only with the consent of the
Certificate  Insurer (if no Certificate Insurer Default exists and is continuing
and the Class A  Certificates  are  outstanding  or any  amounts are owed to the
Certificate Insurer under the Insurance Agreement), (i) to cure any ambiguity or
mistake,  (ii) to correct  or  supplement  any  provisions  herein  which may be
defective or inconsistent  with any other provisions herein or (iii) to make any
other  provisions  with  respect  to  matters or  questions  arising  under this
Agreement or the Certificate  Insurance  Policy, as the case may be, which shall
not be inconsistent  with the provisions of this Agreement;  PROVIDED,  HOWEVER,
that any such action  listed in clause (i)  through  (iii) above shall be deemed
not to adversely  affect in any respect the interests of any  Certificateholder,
if evidenced by (i) written notice to the Depositor, the Master Servicer and the
Trustee  from the  Rating  Agencies  that  such  action  will not  result in the
reduction or withdrawal of the rating of any  outstanding  Class of Certificates
with  respect  to which it is a Rating  Agency  or (ii) an  Opinion  of  Counsel
delivered to the Master Servicer and the Trustee.

          In  addition,  this  Agreement  may be  amended  from  time to time by
Seller, the Depositor, the Master Servicer, the Special Servicer and the Trustee
with the consent of the Certificate Insurer (if no Insurer Default exists and is
continuing and the Class A Certificates  are outstanding or any amounts are owed
to the  Certificate  Insurer under the Insurance  Agreement) with the consent of
the Majority  Certificateholders  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 Certificates;  PROVIDED,
HOWEVER,  that no such  amendment  or waiver  shall (x) reduce in any manner the
amount of, or delay the timing of, payments on the Certificates or distributions
or payments under the Certificate Insurance Policy which are required to be made
on any Certificate  without the consent of the Holder of such  Certificate,  (y)
adversely  affect in any  material  respect the  interests of the Holders of any
Class of  Certificates  in a manner other than as described in clause (x) above,
without the consent of the Holders of Certificates  of such Class  evidencing at
least a 66% Percentage  Interest in such Class,  or (z) reduce the percentage of
Voting Rights required by clause (y) above without the consent of the Holders of
all Certificates of such Class then outstanding.  Upon approval of an amendment,
a copy of such amendment shall be sent to the Rating Agencies.

          Notwithstanding  any provision of this Agreement to the contrary,  the
Trustee  shall not consent to any  amendment to this  Agreement  unless it shall
have first received an Opinion of Counsel,  delivered by (and at the expense of)
the Person  seeking such  Amendment,  to the effect that such amendment will not
result in the  imposition of a tax on any REMIC  constituting  part of the Trust
Fund pursuant to the REMIC  Provisions or cause any REMIC  constituting  part of
the Trust Fund to fail to  qualify as a REMIC at any time that any  Certificates
are  outstanding  and that the  amendment is being made in  accordance  with the
terms hereof.

          Promptly  after the execution of any such  amendment the Trustee shall
furnish,  at the  expense of the Person that  requested  the  amendment  if such
Person is Seller or the Master  Servicer  (but in no event at the expense of the
Trustee),  otherwise at the expense of the Trust,  a copy of such  amendment and
the Opinion of Counsel referred to in the immediately preceding paragraph to the
Master Servicer, the Certificate Insurer and each Rating Agency.

          It shall not be necessary for the consent of Certificateholders  under
this Section  12.01 to approve the  particular  form of any proposed  amendment;
instead 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 Trustee may prescribe.

          The  Trustee  may,  but  shall not be  obligated  to,  enter  into any
amendment  pursuant to this 12.01  Section that  affects its rights,  duties and
immunities under this Agreement or otherwise.

          Section 12.02 RECORDATION OF AGREEMENT; COUNTERPARTS.

          To the extent  permitted by applicable  law, this Agreement 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
properties  subject to the Mortgages are situated,  and in any other appropriate
public  recording  office or elsewhere,  such  recordation to be effected by the
Master  Servicer  at the  expense  of the  Trust,  but only  upon  direction  of
Certificateholders  or the  Certificate  Insurer  accompanied  by an  Opinion of
Counsel to the effect that such recordation  materially and beneficially affects
the interests of the Certificateholders.

          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 together constitute but
one and the same instrument.

          Section 12.03 LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

          The death or incapacity of any Certificateholder shall not (i) operate
to terminate this Agreement or the Trust, (ii) entitle such  Certificateholder's
legal  representatives  or heirs to claim an accounting or to take any action or
proceeding  in any court for a  partition  or winding up of the Trust,  or (iii)
otherwise  affect the rights,  obligations and liabilities of the parties hereto
or any of them.

          Except as expressly  provided for herein, no  Certificateholder  shall
have any right to vote or in any manner  otherwise  control  the  operation  and
management of the Trust,  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 person 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 of any provision
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  Trustee a written  notice of default and of
the continuance  thereof,  as hereinbefore  provided,  and unless also (i) if no
Certificate Insurer Default exists and is continuing, the Certificate Insurer so
agrees or (ii) if a Certificate  Insurer  Default exists and is continuing,  the
Holders of Certificates entitled to at least 25% of the Voting Rights shall have
made  written  request  upon the  Trustee  to  institute  such  action,  suit or
proceeding  in its own name as Trustee  hereunder  and shall have offered to the
Trustee such reasonable indemnity as it may require against the costs,  expenses
and liabilities to be incurred  therein or thereby,  and the Trustee for 15 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 is
understood and intended, and expressly covenanted by each Certificateholder with
every other  Certificateholder  and the Trustee,  that no one or more Holders of
Certificates  shall  have any  right in any  manner  whatever  by  virtue of any
provision of this  Agreement to affect,  disturb or prejudice  the rights of the
Holders  of any  other of such  Certificates,  or to  obtain  or seek to  obtain
priority  over or  preference  to any  other  such  Holder,  which  priority  or
preference is not otherwise  provided for herein,  or to enforce any right under
this Agreement,  except in the manner herein provided and for the equal, ratable
and common benefit of all Certificateholders. For the protection and enforcement
of the provisions of this Section 12.03 each and every Certificateholder and the
Trustee  shall be entitled  to such  relief as can be given  either at law or in
equity.

          Section 12.04 GOVERNING LAW; JURISDICTION.

State of New York,  and the  obligations,  rights and  remedies  of the  parties

relating  hereto brought in any such courts,  irrevocably  waives any claim that
any such suit,  action or proceeding  brought in any such court has been brought
in any inconvenient  forum and further  irrevocably  waives the right to object,
with  respect to such  claim,  suit,  action or  proceeding  brought in any such

          Section 12.09 FURTHER ASSURANCES.

          Notwithstanding  any other  provision of this  Agreement,  neither the
Regular  Certificateholders nor the Trustee shall have any obligation to consent
to any  amendment  or  modification  of this  Agreement  unless  they  have been
provided reasonable  security or indemnity against their out-of-pocket  expenses

          Section 12.10 BENEFITS OF AGREEMENT.

          Nothing  in  this  Agreement  or in  the  Certificates,  expressed  or
implied,  shall  give to any  Person,  other  than the  Certificateholders,  the
Certificate Insurer and the parties hereto and their successors  hereunder,  any
benefit or any legal or equitable right, remedy or claim under this Agreement.

          Section 12.11 ACTS OF CERTIFICATEHOLDERS.

          (a) Any request, demand,  authorization,  direction,  notice, consent,
waiver or other  action  provided by this  Agreement to be given or taken by the
Certificateholders  may be embodied in and evidenced by one or more  instruments
of substantially similar tenor signed by such Certificateholders in person or by
agent duly  appointed in writing,  and such action shall become  effective  when
such  instrument or  instruments  are  delivered to the Trustee,  Seller and the
Master Servicer. Such instrument or instruments (and the action embodied therein
and  evidenced  thereby)  are herein  sometimes  referred to as the "act" of the
Certificateholders signing such instrument or instruments. Proof of execution of
any  such  instrument  or of a  writing  appointing  any  such  agent  shall  be
sufficient  for any purpose of this  Agreement  and  conclusive  in favor of the

instrument  or  writing  may be proved  by the  affidavit  of a witness  of such
execution or by the  certificate of a notary public or other officer  authorized
by law to take acknowledgments of deeds,  certifying that the individual signing
such instrument or writing  acknowledged to him the execution thereof.  Whenever
such  execution  is by a  signer  acting  in a  capacity  other  than his or her
individual  capacity,  such  certificate  or  affidavit  shall  also  constitute
sufficient proof of his authority.

          (c) Any request, demand,  authorization,  direction,  notice, consent,
waiver or other action by any  Certificateholder  shall bind every future Holder
of such  Certificate  and the  Holder  of  every  Certificate  issued  upon  the
registration of transfer thereof or in exchange therefor or in lieu thereof,  in
respect of anything  done,  omitted or suffered to be done by the Trustee or the
Trust in reliance  thereon,  whether or not notation of such action is made upon
such Certificate.

                                    Class A-1

      evidencing the Percentage Interest in the distributions allocable to
      the  Certificates  of the  above-referenced  Class with respect to a
      group of fixed-rate and adjustable-rate  mortgage loans ("Loan Group
      I"),  which comprise part of the Trust  consisting  primarily of two
      groups of first  lien  residential  mortgage  loans  (the  "Mortgage
      Loans")


                 ASSET BACKED FUNDING CORPORATION, as Depositor

      Principal in respect of this Certificate is  distributable  monthly as set
forth herein.  Accordingly,  the Certificate Principal Balance of this Class A-1
Certificate  at any time  may be less  than the  Initial  Certificate  Principal
Balance  set forth on the face  hereof,  as  described  herein.  This  Class A-1
Certificate  does not evidence an  obligation  of, or an interest in, and is not
guaranteed  by the  Depositor,  the  Seller,  the Master  Servicer,  the Special
Servicer or the Trustee referred to below or any of their respective affiliates.

      This certifies  that CEDE & CO. is the registered  owner of the Percentage
Interest  evidenced  by this Class A-1  Certificate  (obtained  by dividing  the
Initial  Certificate  Principal  Balance  of this Class A-1  Certificate  by the
Original Class Certificate  Principal Balance) in certain monthly  distributions
with respect to a Trust consisting  primarily of the Mortgage Loans deposited by
Asset  Backed  Funding  Corporation  (the  "Depositor").  The Trust was  created
pursuant to a Pooling and Servicing  Agreement  dated as of October 1, 1999 (the
"Agreement")  among the Depositor,  Pan American  Bank,  FSB, as seller (in such
capacity,  the  "Seller")  and master  servicer (in such  capacity,  the "Master
Servicer"),   Fairbanks   Capital  Corp.,  as  special  servicer  (the  "Special
Servicer"),  and Bankers Trust Company of  California,  N.A., a New York banking
corporation,  as Trustee (the "Trustee").  To the extent not defined herein, the
capitalized terms used herein have the meanings assigned in the Agreement.  This
Class A-1  Certificate  is issued under and is subject to the terms,  provisions
and conditions of the Agreement, to which Agreement the Holder of this Class A-1
Certificate by virtue of the acceptance  hereof assents and by which such Holder
is bound.

      Reference  is hereby  made to the  further  provisions  of this  Class A-1
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

      Solely for U.S. federal income tax purposes,  this Certificate  represents
(i) a beneficial  interest in a "regular  interest"  in a "real estate  mortgage
investment conduit" as those terms are defined,  respectively,  in Sections 860G
and 860D of the Internal Revenue Code of 1986, as amended, and (ii) the right to
receive payments in respect of Group 1 Interest Carryovers.

      This Class A-1 Certificate  shall not be entitled to any benefit under the
Agreement  or be valid  for any  purpose  unless  manually  countersigned  by an
authorized signatory of the Trustee.

      IN WITNESS  WHEREOF,  the  Trustee on behalf of the Trust has caused  this
Certificate to be duly executed.

                       [Reverse of Class A-1 Certificate]

                     UNITED PANAM MORTGAGE LOAN TRUST 1999-2
                           Asset Backed Certificates,
                                  Series 1999-2

      This  Certificate  is one  of a  duly  authorized  issue  of  Certificates
designated  as  United  PanAm   Mortgage   Loan  Trust   1999-2,   Asset  Backed
Certificates, Series 1999-2 (herein collectively called the "Certificates"), and
representing  a  beneficial  ownership  interest  in the  Trust  created  by the
Agreement.

      The Certificateholder,  by its acceptance of this Certificate, agrees that
it will look solely to the funds on deposit in the Distribution  Account and the
guarantee provided by the Certificate Insurer for payment hereunder and that the
Trustee is not liable to the  Certificateholders  for any amount  payable  under
this  Certificate  or the  Agreement  or,  except as  expressly  provided in the
Agreement, subject to any liability under the Agreement.

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

      Pursuant to the terms of the Agreement, a distribution will be made on the
25th day of each month or, if such 25th day is not a Business Day then the first
Business  Day  following  such  Distribution  Date  (the  "Distribution  Date"),
commencing on the first  Distribution  Date specified on the face hereof, to the
Person in whose name this  Certificate is registered at the close of business on
the  applicable  Record Date in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be distributed
to Holders of  Certificates  of the Class to which this  Certificate  belongs on
such Distribution Date pursuant to the Agreement.

      Distributions  on this  Certificate  shall be made by check or money order
mailed to the  address  of the  person  entitled  thereto  as it  appears on the
Certificate  Register or, upon the request of a  Certificateholder  owning Class
A-1  Certificates  of  a  Class  having   denominations   aggregating  at  least
$1,000,000,  by wire transfer or otherwise,  as set forth in the Agreement.  The
final  distribution on each  Certificate  will be made in like manner,  but only
upon  presentment  and surrender of such  Certificate at the office or agency of
the  Trustee  specified  in the  notice  to  Certificateholders  of  such  final
distribution.

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

      As provided in the  Agreement and subject to certain  limitations  therein
set forth,  the transfer of this  Certificate is registrable in the  Certificate
Register of the Trustee upon surrender of this  Certificate for  registration of
transfer at the office or agency maintained by the Trustee in New York, New York
accompanied  by a written  instrument  of transfer in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the holder hereof or such
holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates  of the same Class in authorized  denominations  and evidencing the
same aggregate Percentage Interest in the Trust will be issued to the designated
transferee or transferees.

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

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

      The  Depositor,  the Seller and the Trustee and any agent of the Depositor
or the Trustee may treat the Person in whose name this Certificate is registered
as the owner hereof for all purposes, and neither the Depositor, the Trustee nor
any such agent shall be affected by any notice to the contrary.

      On any  Distribution  Date  following  the  date at  which  the  remaining
aggregate  Principal  Balance  of the  Mortgage  Loans  is less  than 10% of the
aggregate Principal Balance of the Mortgage Loans as of their Cut-off Dates, the
Master  Servicer or the  Certificate  Insurer may purchase,  in whole,  from the
Trust the  Mortgage  Loans at a purchase  price  determined  as  provided in the
Agreement.   In  the  event  that  no  such  optional  termination  occurs,  the
obligations  and  responsibilities  created by the Agreement will terminate upon
notice to the  Trustee  upon the later of (A) the payment in full of all amounts
owing to the Certificate  Insurer unless the Certificate Insurer shall otherwise
consent and (B) the earliest of (i) the Distribution Date on which the aggregate
Class Certificate Principal Balance of the Class A Certificates has been reduced
to zero,  (ii) the final payment or other  liquidation of the last Mortgage Loan
in the Trust and (iii) the  Distribution  Date in  October,  2029.  In no event,
however,  will the trust created by the Agreement continue beyond the expiration
of 21 years from the death of the last survivor of the descendants living at the
date of the Agreement of a certain person named in the Agreement.

      Capitalized terms used herein that are defined in the Agreement shall have
the  meanings  ascribed to them in the  Agreement,  and nothing  herein shall be
deemed inconsistent with that meaning.

                                   ----------

      evidencing the Percentage Interest in the distributions allocable to
      the  Certificates  of the  above-referenced  Class with respect to a
      group of fixed-rate and adjustable-rate  mortgage loans ("Loan Group
      II"), which comprise part of the Trust  consisting  primarily of two
      groups of first  lien  residential  mortgage  loans  (the  "Mortgage
      Loans")


                 ASSET BACKED FUNDING CORPORATION, as Depositor

      Principal in respect of this Certificate is  distributable  monthly as set
forth herein.  Accordingly,  the Certificate Principal Balance of this Class A-2
Certificate  at any time  may be less  than the  Initial  Certificate  Principal
Balance  set forth on the face  hereof,  as  described  herein.  This  Class A-2
Certificate  does not evidence an  obligation  of, or an interest in, and is not
guaranteed  by the  Depositor,  the  Seller,  the Master  Servicer,  the Special
Servicer or the Trustee referred to below or any of their respective affiliates.

      This certifies  that CEDE & CO. is the registered  owner of the Percentage
Interest  evidenced  by this Class A-2  Certificate  (obtained  by dividing  the
Initial  Certificate  Principal  Balance  of this Class A-2  Certificate  by the
Original Class Certificate  Principal Balance) in certain monthly  distributions
with respect to a Trust consisting  primarily of the Mortgage Loans deposited by
Asset  Backed  Funding  Corporation  (the  "Depositor").  The Trust was  created
pursuant to a Pooling and Servicing  Agreement  dated as of October 1, 1999 (the
"Agreement")  among the Depositor,  Pan American  Bank,  FSB, as seller (in such
capacity,  the  "Seller")  and master  servicer (in such  capacity,  the "Master
Servicer"),   Fairbanks   Capital  Corp.,  as  special  servicer  (the  "Special
Servicer"),  and Bankers Trust Company of  California,  N.A., a New York banking
corporation,  as Trustee (the "Trustee").  To the extent not defined herein, the
capitalized terms used herein have the meanings assigned in the Agreement.  This
Class A-2  Certificate  is issued under and is subject to the terms,  provisions
and conditions of the Agreement, to which Agreement the Holder of this Class A-2
Certificate by virtue of the acceptance  hereof assents and by which such Holder
is bound.

      Reference  is hereby  made to the  further  provisions  of this  Class A-2
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

      Solely for U.S. federal income tax purposes,  this Certificate  represents
(i) a beneficial  interest in a "regular  interest"  in a "real estate  mortgage
investment conduit" as those terms are defined,  respectively,  in Sections 860G
and 860D of the Internal Revenue Code of 1986, as amended, and (ii) the right to
receive payments in respect of Group I Interest Carryovers.

      This Class A-2 Certificate  shall not be entitled to any benefit under the
Agreement  or be valid  for any  purpose  unless  manually  countersigned  by an
authorized signatory of the Trustee.

      IN WITNESS  WHEREOF,  the  Trustee on behalf of the Trust has caused  this
Certificate to be duly executed.

                     UNITED PANAM MORTGAGE LOAN TRUST 1999-2
                           Asset Backed Certificates,
                                  Series 1999-2

      This  Certificate  is one  of a  duly  authorized  issue  of  Certificates
designated  as  United  PanAm   Mortgage   Loan  Trust   1999-2,   Asset  Backed
Certificates, Series 1999-2 (herein collectively called the "Certificates"), and
representing  a  beneficial  ownership  interest  in the  Trust  created  by the
Agreement.

      The Certificateholder,  by its acceptance of this Certificate, agrees that
it will look solely to the funds on deposit in the Distribution  Account and the
guarantee provided by the Certificate Insurer for payment hereunder and that the
Trustee is not liable to the  Certificateholders  for any amount  payable  under
this  Certificate  or the  Agreement  or,  except as  expressly  provided in the
Agreement, subject to any liability under the Agreement.

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

      Pursuant to the terms of the Agreement, a distribution will be made on the
25th day of each month or, if such 25th day is not a Business Day then the first
Business  Day  following  such  Distribution  Date  (the  "Distribution  Date"),
commencing on the first  Distribution  Date specified on the face hereof, to the
Person in whose name this  Certificate is registered at the close of business on
the  applicable  Record Date in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be distributed
to Holders of  Certificates  of the Class to which this  Certificate  belongs on
such Distribution Date pursuant to the Agreement.

      Distributions  on this  Certificate  shall be made by check or money order
mailed to the  address  of the  person  entitled  thereto  as it  appears on the
Certificate  Register or, upon the request of a  Certificateholder  owning Class
A-2  Certificates  of  a  Class  having   denominations   aggregating  at  least
$1,000,000,  by wire transfer or otherwise,  as set forth in the Agreement.  The
final  distribution on each  Certificate  will be made in like manner,  but only
upon  presentment  and surrender of such  Certificate at the office or agency of
the  Trustee  specified  in the  notice  to  Certificateholders  of  such  final
distribution.

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

      As provided in the  Agreement and subject to certain  limitations  therein
set forth,  the transfer of this  Certificate is registrable in the  Certificate
Register of the Trustee upon surrender of this  Certificate for  registration of
transfer at the office or agency maintained by the Trustee in New York, New York
accompanied  by a written  instrument  of transfer in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the holder hereof or such
holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates  of the same Class in authorized  denominations  and evidencing the
same aggregate Percentage Interest in the Trust will be issued to the designated
transferee or transferees.

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

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

      The  Depositor,  the Seller and the Trustee and any agent of the Depositor
or the Trustee may treat the Person in whose name this Certificate is registered
as the owner hereof for all purposes, and neither the Depositor, the Trustee nor
any such agent shall be affected by any notice to the contrary.

      On any  Distribution  Date  following  the  date at  which  the  remaining
aggregate  Principal  Balance  of the  Mortgage  Loans  is less  than 10% of the
aggregate Principal Balance of the Mortgage Loans as of their Cut-off Dates, the
Master  Servicer or the  Certificate  Insurer may purchase,  in whole,  from the
Trust the  Mortgage  Loans at a purchase  price  determined  as  provided in the
Agreement.   In  the  event  that  no  such  optional  termination  occurs,  the
obligations  and  responsibilities  created by the Agreement will terminate upon
notice to the  Trustee  upon the later of (A) the payment in full of all amounts
owing to the Certificate  Insurer unless the Certificate Insurer shall otherwise
consent and (B) the earliest of (i) the Distribution Date on which the aggregate
Class Certificate Principal Balance of the Class A Certificates has been reduced
to zero,  (ii) the final payment or other  liquidation of the last Mortgage Loan
in the Trust and (iii) the  Distribution  Date in  October,  2029.  In no event,
however,  will the trust created by the Agreement continue beyond the expiration
of 21 years from the death of the last survivor of the descendants living at the
date of the Agreement of a certain person named in the Agreement.

      Capitalized terms used herein that are defined in the Agreement shall have
the  meanings  ascribed to them in the  Agreement,  and nothing  herein shall be
deemed inconsistent with that meaning.

                                  Series 1999-2
                                     Class X

     evidencing the Percentage Interest in the distributions allocable to
     the Certificates of the  above-referenced  Class with respect to the
     Trust  consisting  primarily of two groups of first lien  fixed-rate
     and  adjustable-rate   residential  mortgage  loans  (the  "Mortgage
     Loans")


                 ASSET BACKED FUNDING CORPORATION, as Depositor


      Distributions in respect of this Certificate are distributable  monthly as
set forth herein.  This Class X Certificate  does not evidence an obligation of,
or an interest  in, and is not  guaranteed  by the  Depositor,  the Seller,  the
Master  Servicer  or the Trustee  referred  to below or any of their  respective
affiliates.  Neither this  Certificate  nor the Mortgage Loans are guaranteed or
insured by any governmental agency or instrumentality.

      This certifies that PAN AMERICAN BANK, FSB is the registered  owner of the
Percentage  Interest  evidenced by this Class X Certificate  in certain  monthly
distributions with respect to a Trust consisting primarily of the Mortgage Loans
deposited by Asset Backed Funding  Corporation (the "Depositor").  The Trust was
created  pursuant to a Pooling and  Servicing  Agreement  dated as of October 1,
1999 (the  "Agreement")  among the Depositor,  Pan American Bank, FSB, as seller
(in such  capacity,  the "Seller") and master  servicer (in such  capacity,  the
"Master  Servicer"),  Fairbanks Capital Corp., as special servicer (the "Special
Servicer"),  and Bankers Trust Company of  California,  N.A., a New York banking
corporation,  as Trustee (the "Trustee").  To the extent not defined herein, the
capitalized terms used herein have the meanings assigned in the Agreement.  This
Class X Certificate is issued under and is subject to the terms,  provisions and
conditions  of the  Agreement,  to which  Agreement  the  Holder of this Class X
Certificate by virtue of the acceptance  hereof assents and by which such Holder
is bound.

      This  Certificate does not have a principal  balance or pass-through  rate
and will be  entitled  to  distributions  only to the  extent  set  forth in the
Agreement. In addition, any distribution of the proceeds of any remaining assets
of the  Trust  will  be  made  only  upon  presentment  and  surrender  of  this
Certificate at the Corporate Trust Office or the office or agency  maintained by
the Trustee in New York, New York.

      No  transfer  of a  Certificate  of this Class  shall be made  unless such
transfer is made pursuant to an effective  registration  statement under the Act
and any  applicable  state  securities  laws or is exempt from the  registration
requirements under said Act and such laws. In the event that a transfer is to be
made in  reliance  upon an  exemption  from the Act and such  laws,  in order to
assure compliance with the Act and such laws, the Certificateholder  desiring to
effect such transfer and such  Certificateholder's  prospective transferee shall
each certify to the Trustee and the  Depositor in writing the facts  surrounding
the  transfer.  In the event that such a transfer not is to be made  pursuant to
Rule 144A of the Act there shall be delivered  to the Trustee and the  Depositor
an Opinion of Counsel that such  transfer  may be made  pursuant to an exemption
from the Act,  which  Opinion of Counsel shall not be obtained at the expense of
the  Trustee,  the Seller or the  Depositor  or there shall be  delivered to the
Trustee and the  Depositor a transferor  certificate  by the  transferor  and an
investment  letter  shall be  executed  by the  transferee.  The  Holder  hereof
desiring to effect such transfer shall,  and does hereby agree to, indemnify the
Trustee and the Depositor  against any liability that may result if the transfer
is not so exempt or is not made in accordance with such federal and state laws.

      No  transfer  of a  Certificate  of this  Class  shall be made  unless the
Trustee shall have received (i) a  representation  letter from the transferee of
such  Certificate,  acceptable to and in form and substance  satisfactory to the
Trustee,  to the effect that such  transferee  is not an employee  benefit  plan
subject to Section 406 of ERISA or Section 4975 of the Code, nor a person acting
on behalf of any such plan, which representation  letter shall not be an expense
of the Trustee,  (ii) if the purchaser is an insurance company, 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 PTCE 95-60,  or (iii) an Opinion of Counsel with respect to certain  ERISA
matters  described  in the  Agreements.  Notwithstanding  anything  else  to the
contrary herein,  any purported transfer of a Certificate of this Class to or on
behalf of an employee  benefit  plan subject to ERISA or to the Code without the
opinion of counsel  satisfactory to the Trustee as described above shall be void
and of no effect.

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

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

                     UNITED PANAM MORTGAGE LOAN TRUST 1999-2
                           Asset Backed Certificates,
                                  Series 1999-2

      This  Certificate  is one  of a  duly  authorized  issue  of  Certificates
designated  as  United  PanAm   Mortgage   Loan  Trust   1999-2,   Asset  Backed
Certificates, Series 1999-2 (herein collectively called the "Certificates"), and
representing  a  beneficial  ownership  interest  in the  Trust  created  by the
Agreement.

      The Certificateholder,  by its acceptance of this Certificate, agrees that
it will look  solely to the funds on deposit  in the  Distribution  Account  for
payment  hereunder and that the Trustee is not liable to the  Certificateholders
for any amount  payable  under this  Certificate  or the Agreement or, except as
expressly  provided  in the  Agreement,  subject  to  any  liability  under  the
Agreement.

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

      Pursuant to the terms of the Agreement, a distribution will be made on the
25th day of each month or, if such 25th day is not a Business Day then the first
Business  Day  following  such  Distribution  Date  (the  "Distribution  Date"),
commencing on the first  Distribution  Date specified on the face hereof, to the
Person in whose name this  Certificate is registered at the close of business on
the  applicable  Record Date in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be distributed
to Holders of  Certificates  of the Class to which this  Certificate  belongs on
such Distribution Date pursuant to the Agreement.

      Distributions  on this  Certificate  shall be made by check or money order
mailed to the  address  of the  person  entitled  thereto  as it  appears on the
Certificate Register or, upon the request of a Certificateholder  owning Class X
Certificates having a 100% Percentage  Interest,  by Wire transfer or otherwise,
as set forth in the Agreement.  The final  distribution on each Certificate will
be made in  like  manner,  but  only  upon  presentment  and  surrender  of such
Certificate  at the office or agency of the Trustee  specified  in the notice to
Certificateholders of such final distribution.

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

      As provided in the  Agreement and subject to certain  limitations  therein
set forth,  the transfer of this  Certificate is registrable in the  Certificate
Register of the Trustee upon surrender of this  Certificate for  registration of
transfer at the office or agency maintained by the Trustee in New York, New York
accompanied  by a written  instrument  of transfer in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the holder hereof or such
holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates  of the same Class in authorized  denominations  and evidencing the
same aggregate Percentage Interest in the Trust will be issued to the designated
transferee or transferees.

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

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

      The  Depositor,  the Seller and the Trustee and any agent of the Depositor
or the Trustee may treat the Person in whose name this Certificate is registered
as the owner hereof for all purposes, and neither the Depositor, the Trustee nor
any such agent shall be affected by any notice to the contrary.

      On any  Distribution  Date  following  the  date at  which  the  remaining
aggregate  Principal  Balance  of the  Mortgage  Loans  is less  than 10% of the
aggregate  Principal  Balance of the Mortgage  Loans as of the Cut-off Date, the
Master  Servicer or the  Certificate  Insurer may purchase,  in whole,  from the
Trust the  Mortgage  Loans at a purchase  price  determined  as  provided in the
Agreement.   In  the  event  that  no  such  optional  termination  occurs,  the
obligations  and  responsibilities  created by the Agreement will terminate upon
notice to the  Trustee  upon the later of (A) the payment in full of all amounts
owing to the Certificate  Insurer unless the Certificate Insurer shall otherwise
consent and (B) the earliest of (i) the Distribution Date on which the aggregate
Class Certificate Principal Balance of the Class X Certificates has been reduced
to zero,  (ii) the final payment or other  liquidation of the last Mortgage Loan
in the Trust and (iii) the  Distribution  Date in  October,  2029.  In no event,
however,  will the trust created by the Agreement continue beyond the expiration
of 21 years from the death of the last survivor of the descendants living at the
date of the Agreement of a certain person named in the Agreement.

      Capitalized terms used herein that are defined in the Agreement shall have
the  meanings  ascribed to them in the  Agreement,  and nothing  herein shall be
deemed inconsistent with that meaning.

                     UNITED PANAM MORTGAGE LOAN TRUST 1999-2
                           Asset Backed Certificates,
                                  Series 1999-2
                                     Class R

      evidencing the Percentage Interest in the distributions allocable to
      the Certificates of the  above-referenced  Class with respect to the
      Trust  consisting  primarily of two groups of first lien  fixed-rate
      and  adjustable-rate   residential  mortgage  loans  (the  "Mortgage
      Loans")



                 ASSET BACKED FUNDING CORPORATION, as Depositor


      This  Certificate  does not evidence an obligation  of, or an interest in,
and is not guaranteed by the Depositor,  the Seller,  the Master  Servicer,  the
Special  Servicer  or the Trustee  referred to below or any of their  respective
affiliates.  Neither this  Certificate  nor the Mortgage Loans are guaranteed or
insured by any governmental agency or instrumentality.

      This certifies that Pan American Bank, FSB is the registered  owner of the
Percentage  Interest  evidenced  by  this  Certificate  specified  above  in the
interest  represented by all Certificates of the Class to which this Certificate
belongs in a Trust consisting primarily of the Mortgage Loans deposited by Asset
Backed Funding Corporation (the "Depositor").  The Trust was created pursuant to
a Pooling and Servicing  Agreement dated as of October 1, 1999 (the "Agreement")
among the Depositor,  Pan American Bank,  FSB, as seller (in such capacity,  the
"Seller")  and  master  servicer  (in such  capacity,  the  "Master  Servicer"),
Fairbanks  Capital  Corp.,  as special  servicer (the "Special  Servicer"),  and
Bankers Trust Company of California,  N.A., a New York banking  corporation,  as
trustee (the "Trustee"). To the extent not defined herein, the capitalized terms
used herein have the meanings  assigned in the  Agreement.  This  Certificate is
issued  under and is subject  to the terms,  provisions  and  conditions  of the
Agreement,  to which  Agreement the Holder of this  Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

      This  Certificate does not have a principal  balance or pass-through  rate
and will be  entitled  to  distributions  only to the  extent  set  forth in the
Agreement. In addition, any distribution of the proceeds of any remaining assets
of the  Trust  will  be  made  only  upon  presentment  and  surrender  of  this
Certificate at the Corporate Trust Office or the office or agency  maintained by
the Trustee in New York, New York.

      No  transfer  of a  Certificate  of this Class  shall be made  unless such
transfer is made pursuant to an effective  registration  statement under the Act
and any  applicable  state  securities  laws or is exempt from the  registration
requirements under said Act and such laws. In the event that a transfer is to be
made in  reliance  upon an  exemption  from the Act and such  laws,  in order to
assure compliance with the Act and such laws, the Certificateholder  desiring to
effect such transfer and such  Certificateholder's  prospective transferee shall
each certify to the Trustee and the  Depositor in writing the facts  surrounding
the  transfer.  In the event that such a transfer is not to be made  pursuant to
Rule 144A of the Act,  there shall be delivered to the Trustee and the Depositor
of an Opinion of Counsel that such transfer may be made pursuant to an exemption
from the Act,  which  Opinion of Counsel shall not be obtained at the expense of
the Trustee or the Depositor; or there shall be delivered to the Trustee and the
Depositor a transferor  certificate by the  transferor and an investment  letter
shall be executed by the  transferee.  The Holder hereof desiring to effect such
transfer  shall,  and does  hereby  agree  to,  indemnify  the  Trustee  and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

      No  transfer  of a  Certificate  of this  Class  shall be made  unless the
Trustee  shall  have  received  either  (i) a  representation  letter  from  the
transferee  of  such  Certificate,  acceptable  to and  in  form  and  substance
satisfactory  to the  Trustee,  to the  effect  that such  transferee  is not an
employee  benefit  plan  subject to Section 406 of ERISA or Section  4975 of the
Code,  nor a person  acting  on behalf of any such  plan,  which  representation
letter  shall not be an  expense of the  Trustee,  or (ii) an Opinion of Counsel
with   respect  to  certain   ERISA   matters   described   in  the   Agreement.
Notwithstanding  anything else to the contrary herein, any purported transfer of
a Certificate of this Class to or on behalf of an employee  benefit plan subject
to ERISA or to the Code  without  the  opinion  of counsel  satisfactory  to the
Trustee as described above shall be void and of no effect.

      Each Holder of this  Certificate will be deemed to have agreed to be bound
by  the  restrictions  of  the  Agreement,  including  but  not  limited  to the
restrictions that (i) each person holding or acquiring any Ownership Interest in
this Certificate must be a Permitted  Transferee,  (ii) no Ownership Interest in
this  Certificate  may be transferred  without  delivery to the Trustee of (a) a
transfer affidavit of the proposed transferee and (b) a transfer  certificate of
the  transferor,  each of such  documents  to be in the  form  described  in the
Agreement, (iii) each person holding or acquiring any Ownership Interest in this
Certificate must agree to require a transfer affidavit and to deliver a transfer
certificate  to the Trustee as required  pursuant  to the  Agreement,  (iv) each
person holding or acquiring an Ownership Interest in this Certificate must agree
not to  transfer an  Ownership  Interest  in this  Certificate  if it has actual
knowledge that the proposed transferee is not a Permitted Transferee and (v) any
attempted or purported transfer of any Ownership Interest in this Certificate in
violation of such restrictions will be absolutely null and void and will vest no
rights in the  purported  transferee.  The Trustee  will  provide  the  Internal
Revenue Service and any pertinent persons with the information needed to compute
the tax imposed under the applicable tax laws on transfers of residual interests
to disqualified  organizations,  if any person other than a Permitted Transferee
acquires an  Ownership  Interest on a Class R  Certificate  in  violation of the
restrictions mentioned above.

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

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

                                     * * *

                     United PanAm Mortgage Loan Trust 1999-2
                           Asset Backed Certificates,
                                  Series 1999-2

      This  Certificate  is one  of a  duly  authorized  issue  of  Certificates
designated  as  United  PanAm   Mortgage   Loan  Trust   1999-2,   Asset  Backed
Certificates, Series 1999-2 (herein collectively called the "Certificates"), and
representing  a  beneficial  ownership  interest  in the  Trust  created  by the
Agreement.

      The Certificateholder,  by its acceptance of this Certificate, agrees that
it will look solely to funds on deposit in the Distribution  Account for payment
hereunder and that the Trustee is not liable to the  Certificateholders  for any
amount  payable under this  Certificate or the Agreement or, except as expressly
provided in the Agreement, subject to any liability under the Agreement.

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

      Pursuant to the terms of the Agreement, a distribution will be made on the
25th day of each month or, if such 25th day is not a Business Day then the first
Business  Day  following  such  Distribution  Date  (the  "Distribution  Date"),
commencing on the first  Distribution  Date specified on the face hereof, to the
Person in whose name this  Certificate is registered at the close of business on
the  applicable  Record Date in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be distributed
to Holders of  Certificates  of the Class to which this  Certificate  belongs on
such Distribution Date pursuant to the Agreement.

      Distributions  on this  Certificate  shall be made by check or money order
mailed to the  address  of the  person  entitled  thereto  as it  appears on the
Certificate Register or, upon the request of a Certificateholder  owning Class R
Certificates having a 100% Percentage  Interest,  by wire transfer or otherwise,
as set forth in the Agreement.  The final  distribution on each Certificate will
be made in  like  manner,  but  only  upon  presentment  and  surrender  of such
Certificate  at the office or agency of the Trustee  specified  in the notice to
Certificateholders of such final distribution.

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

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

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

      The  Depositor,  the Seller and the Trustee and any agent of the Depositor
or the Trustee may treat the Person in whose name this Certificate is registered
as the owner hereof for all purposes, and neither the Depositor, the Trustee nor
any such agent shall be affected by any notice to the contrary.

      On any  Distribution  Date  following  the  date at  which  the  remaining
aggregate  Principal  Balance  of the  Mortgage  Loans  is less  than 10% of the
aggregate  Principal  Balance  of the  Mortgage  Loans  as of the  Cut-off  Date
specified in the Agreement,  the Master Servicer or the Certificate  Insurer may
purchase,  in whole,  from the  Trust the  Mortgage  Loans at a  purchase  price
determined  as provided  in the  Agreement.  In the event that no such  optional
termination  occurs,  the  obligations  and  responsibilities   created  by  the
Agreement  will  terminate  upon notice to the Trustee upon the later of (A) the
payment  in full of all  amounts  owing to the  Certificate  Insurer  unless the
Certificate  Insurer  shall  otherwise  consent and (B) the  earliest of (i) the
Distribution Date on which the aggregate Class Certificate  Principal Balance of
the Class A  Certificates  has been reduced to zero,  (ii) the final  payment or
other  liquidation  of the  last  Mortgage  Loan  in the  Trust  and  (iii)  the
Distribution Date in October, 2029. In no event, however, will the trust created
by the Agreement  continue  beyond the  expiration of 21 years from the death of
the last  survivor of the  descendants  living at the date of the Agreement of a
certain person named in the Agreement.

      Capitalized terms used herein that are defined in the Agreement shall have
the  meanings  ascribed to them in the  Agreement,  and nothing  herein shall be
deemed inconsistent with that meaning.

                        )     ss.:
COUNTY OF               )

      The undersigned, being first duly sworn, deposes and says as follows:

      1.    The   undersigned  is  an  officer  of  ___________,   the  proposed
Transferee of an Ownership Interest in a Class R Certificate (the "Certificate")
issued  pursuant to the  Pooling and  Servicing  Agreement,  (the  "Agreement"),
relating  to the  above-referenced  Certificates,  among  Asset  Backed  Funding
Corporation, as depositor, Pan American Bank, FSB, as seller and master servicer
(the  "Seller"  and "Master  Servicer"),  Fairbanks  Capital  Corp.,  as special
servicer,  and  Bankers  Trust  Company of  California,  N.A.,  as trustee  (the
"Trustee"').  Capitalized  terms used,  but not  defined  herein or in Exhibit 1
hereto,  shall have the meanings  ascribed to such terms in the  Agreement.  The
Transferee has  authorized  the  undersigned to make this affidavit on behalf of
the Transferee.

      2.    The  Transferee  is, as of the date  hereof,  and will be, as of the
date of the Transfer,  a Permitted  Transferee.  The Transferee is acquiring its
Ownership  Interest in the Certificate either (i) for its own account or (ii) as
nominee,  trustee  or agent  for  another  Person  and has  attached  hereto  an
affidavit from such Person in substantially the same form as this affidavit. The
Transferee has no knowledge that any such affidavit is false.

      3.    The  Transferee has been advised of, and understands  that (i) a tax
will be  imposed  on  Transfers  of the  Certificate  to  Persons  that  are not
Permitted Transferees;  (ii) such tax will be imposed on the transferor,  or, if
such  Transfer  is  through  an agent  (which  includes  a  broker,  nominee  or
middleman) for a Person that is not a Permitted  Transferee,  on the agent;  and
(iii) the Person otherwise liable for the tax shall be relieved of liability for
the tax if the subsequent  Transferee furnished to such Person an affidavit that
such  subsequent  Transferee  is a  Permitted  Transferee  and,  at the  time of
Transfer,  such Person  does not have actual  knowledge  that the  affidavit  is
false.

      4.    The  Transferee has been advised of, and understands that a tax will
be imposed on a  "pass-through  entity"  holding the  Certificate if at any time
during  the  taxable  year of the  pass-through  entity a  Person  that is not a
Permitted  Transferee  is the record  holder of an interest in such entity.  The
Transferee  understands  that such tax will not be imposed  for any period  with
respect to which the  record  holder  furnishes  to the  pass-through  entity an
affidavit that such record holder is a Permitted Transferee and the pass-through
entity does not have actual  knowledge that such  affidavit is false.  (For this
purpose, a "pass-through entity" includes a regulated investment company, a real
estate  investment  trust or common trust fund, a partnership,  trust or estate,
and certain cooperatives and, except as may be provided in Treasury Regulations,
persons  holding  interests  in  pass-through  entities as a nominee for another
Person.)

      5.    The Transferee has reviewed the provisions of Section 5.02(d) of the
Agreement  (attached hereto as Exhibit 2 and  incorporated  herein by reference)
and  understands  the legal  consequences  of the  acquisition  of an  Ownership
Interest in the Certificate including,  without limitation,  the restrictions on
subsequent  Transfers  and the  provisions  regarding  voiding the  Transfer and
mandatory sales. The Transferee  expressly agrees to be bound by and to abide by
the provisions of Section 5.02(d) of the Agreement and the restrictions noted on
the face of the  Certificate.  The  Transferee  understands  and agrees that any
breach of any of the  representations  included herein shall render the Transfer
to the Transferee contemplated hereby null and void.

      6.    The  Transferee  agrees to  require a  Transfer  Affidavit  from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in the
Certificate,  and in  connection  with any  Transfer  by a  Person  for whom the
Transferee is acting as nominee,  trustee or agent,  and the Transferee will not
Transfer  its  Ownership   Interest  or  cause  any  Ownership  Interest  to  be
Transferred  to  any  Person  that  the  Transferee  knows  is  not a  Permitted
Transferee.  In  connection  with  any  such  Transfer  by the  Transferee,  the
Transferee  agrees to deliver to the Trustee a certificate  substantially in the
form set forth as Exhibit M to the Agreement (a "Transferor Certificate") to the
effect that such Transferee has no actual knowledge that the Person to which the
Transfer is to be made is not a Permitted Transferee.

      7.    The  Transferee does not have the intention to impede the assessment
or  collection  of any tax  legally  required  to be paid  with  respect  to the
Certificate.

      8.    The Transferee's taxpayer identification number is ______.

      9.    The  Transferee  is  a  U.S.  Person  as  defined  in  Code  Section
7701(a)(30).

      10.   The  Transferee is aware that the  Certificate may be a "noneconomic
residual   interest"  within  the  meaning  of  proposed  Treasury   regulations
promulgated  pursuant  to the  Code and that  the  transferor  of a  noneconomic
residual  interest  will  remain  liable  for any taxes due with  respect to the
income on such residual interest,  unless no significant purpose of the transfer
was to impede the assessment or collection of tax.

      11.   The  Transferee  is not an employee  benefit plan that is subject to
ERISA or a plan that is subject to Section  4975 of the Code,  nor are we acting
on behalf of such a plan.

thereof and any other interest  therein,  whether  direct or indirect,  legal or
beneficial, as owner or as a pledgee.

      "Permitted  Transferee":  Any Person other than (i) the United States, any
State or political  subdivision thereof, or any agency or instrumentality of any
of the foregoing, (ii) a foreign government,  international  organization or any
agency or  instrumentality  of either of the  foregoing,  (iii) an  organization
(except certain  farmers'  cooperatives  described in Code Section 521) which is
exempt from tax imposed by Chapter 1 of the Code  (including  the tax imposed by

States is  includible  in gross  income for  United  States  federal  income tax
purposes  regardless of its  connection  with the conduct of a trade or business
within the United  States,  and any other  Person so  designated  by the Trustee

                        SECTION 5.02(D) OF THE AGREEMENT
                        --------------------------------

      (d)   Except with respect to the initial transfer of the Class X and Class
R Certificates by the Depositor, no transfer,  sale, pledge or other disposition
of any Class X or Class R Certificate  shall be made unless such  disposition is
exempt from the  registration  requirements  of the  Securities  Act of 1933, as
amended (the "1933 Act"), and any applicable state securities laws or is made in
accordance  with the 1933 Act and laws. In the event of any such  transfer,  (i)
unless such  transfer is made in reliance  upon Rule 144A (as  evidenced  by the
investment  letter delivered to the Trustee,  in substantially the form attached
hereto as Exhibit K under the 1933 Act,  the  Trustee  and the  Depositor  shall

Depositor  that such transfer may be made  pursuant to an exemption,  describing
the applicable  exemption and the basis therefor,  from the 1933 Act or is being

as  Exhibit  M)  and  the  transferee  to  execute  an  investment   letter  (in
substantially  the form attached  hereto as Exhibit K) acceptable to and in form
and  substance  reasonably   satisfactory  to  the  Depositor  and  the  Trustee
certifying to the Depositor and the Trustee the facts surrounding such transfer,
which investment letter shall not be an expense of the Trustee or the Depositor.
The Holder of a Class X or Class R Certificate  desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee and the Depositor against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

      No transfer of a Class X or Class R  Certificate  shall be made unless the
Trustee shall have received either (i) a  representation  from the transferee of
such  Certificate,  acceptable to and in form and substance  satisfactory to the
Trustee and the Depositor,  (such requirement is satisfied only by the Trustee's
receipt of a representation letter from the transferee substantially in the form
of Exhibit J hereto, as appropriate),  to the effect that such transferee is not
an employee  benefit  plan or  arrangement  subject to Section 406 of ERISA or a
plan subject to Section 4975 of the Code,  nor a person  acting on behalf of any
such plan or arrangement nor using the assets of any such plan or arrangement to
effect such  transfer or (ii) (in the case of the Class X  Certificates)  if the
purchaser is an insurance  company,  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 PTCE 95-60 or (iii)
in  the  case  of  any  such  Class  X or  Class  R  Certificate  presented  for
registration in the name of an employee  benefit plan subject to ERISA or a plan
or arrangement subject to Section 4975 of the Code (or comparable  provisions of
any  subsequent  enactments),  or a trustee of any such plan or any other person
acting  on  behalf  of any such  plan or  arrangement  or using  such  plan's or
arrangement's  assets,  an Opinion of Counsel  satisfactory to the Trustee which
Opinion of Counsel  shall not be an expense of either the  Trustee or the Trust,
addressed  to the  Trustee,  to the effect that the  purchase or holding of such
Class X or Class R Certificate  will not result in the assets of the Trust being
deemed to be "plan assets" and subject to the prohibited  transaction provisions
of ERISA and the Code and will not  subject  the  Trustee to any  obligation  in
addition to those  expressly  undertaken in this  Agreement or to any liability.
For purposes of clause (i) of the preceding sentence,  such representation shall
be deemed to have been made to the Trustee by the  transferee's  acceptance of a
Class X or Class R Certificate (or the acceptance by a Certificate  Owner of the
beneficial  interest  in any such  Class X or Class R  Certificate)  unless  the
Trustee shall have received from the  transferee an  alternative  representation
acceptable in form and substance to the Depositor. Notwithstanding anything else
to the  contrary  herein,  any  purported  transfer  of a  Class  X or  Class  R
Certificate  to or on behalf of an employee  benefit plan subject to ERISA or to
the  Code  without  the  delivery  to  the  Trustee  of an  Opinion  of  Counsel
satisfactory to the Trustee as described above shall be void and of no effect.

      Each Person who has or who  acquires any  Ownership  Interest in a Class R
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  appointed the Depositor or its designee as its  attorney-in-fact to
negotiate the terms of any mandatory  sale under clause (v) below and to execute
all  instruments of transfer and to do all other things  necessary in connection
with any such  sale,  and the  rights of each  Person  acquiring  any  Ownership
Interest  in a  Class R  Certificate  are  expressly  subject  to the  following
provisions:

            (i) Each Person  holding or acquiring  any  Ownership  Interest in a
      Class R Certificate  shall be a Permitted  Transferee  and shall  promptly
      notify the  Trustee of any change or  impending  change in its status as a
      Permitted Transferee.

            (ii) No Person  shall  acquire an  Ownership  Interest  in a Class R
      Certificate  unless  such  Ownership  Interest  is a  pro  rata  undivided
      interest.

            (iii) In  connection  with any  proposed  transfer of any  Ownership
      Interest in a Class R  Certificate,  the Trustee  shall as a condition  to
      registration  of the  transfer,  require  delivery  to  it,  in  form  and
      substance satisfactory to it, of each of the following:

                  A. an  affidavit  in the form of  Exhibit  L  hereto  from the
            proposed  transferee  to  the  effect  that  such  transferee  is  a
            Permitted  Transferee  and that it is not  acquiring  its  Ownership
            Interest  in the  Class R  Certificate  that is the  subject  of the
            proposed transfer as a nominee,  trustee or agent for any Person who
            is not a Permitted Transferee; and

                  B. a covenant of the  proposed  transferee  to the effect that
            the  proposed  transferee  agrees to be bound by and to abide by the
            transfer restrictions applicable to the Class R Certificates.

            (iv) Any attempted or purported  transfer of any Ownership  Interest
      in a Class R  Certificate  in violation of the  provisions of this Section
      shall  be  absolutely  null  and  void and  shall  vest no  rights  in the
      purported  transferee.  If any purported transferee shall, in violation of
      the provisions of this Section,  become a Holder of a Class R Certificate,
      then the prior  Holder of such  Class R  Certificate  that is a  Permitted
      Transferee shall, upon discovery that the registration of transfer of such
      Class R Certificate was not in fact permitted by this Section, be restored
      to all rights as Holder thereof retroactive to the date of registration of
      transfer  of such  Class R  Certificate.  The  Trustee  shall  be under no
      liability  to any Person for any  registration  of  transfer  of a Class R
      Certificate  that is in fact not  permitted  by this Section or for making
      any distributions due on such Class R Certificate to the Holder thereof or
      taking any other action with  respect to such Holder under the  provisions
      of this Agreement so long as the Trustee received the documents  specified
      in clause (iii).  The Trustee shall be entitled to recover from any Holder
      of a Class R  Certificate  that was in fact not a Permitted  Transferee at
      the time such distributions were made all distributions made on such Class
      R Certificate. Any such distributions so recovered by the Trustee shall be
      distributed and delivered by the Trustee to the prior Holder of such Class
      R Certificate that is a Permitted Transferee.

            (v) If any Person  other than a Permitted  Transferee  acquires  any
      Ownership   Interest  in  a  Class  R  Certificate  in  violation  of  the
      restrictions  in this  Section,  then the Trustee shall have the right but
      not  the  obligation,  without  notice  to the  Holder  of  such  Class  R
      Certificate or any other Person having an Ownership  Interest therein,  to
      notify the Depositor to arrange for the sale of such Class R  Certificate.
      The  proceeds  of  such  sale,  net  of  commissions  (which  may  include
      commissions  payable to the Depositor or its affiliates in connection with
      such  sale),  expenses  and taxes due,  if any,  will be  remitted  by the
      Trustee  to the  previous  Holder of such  Class R  Certificate  that is a
      Permitted Transferee, except that in the event that the Trustee determines
      that the Holder of such Class R  Certificate  may be liable for any amount
      due under this  Section or any other  provisions  of this  Agreement,  the
      Trustee  may  withhold a  corresponding  amount  from such  remittance  as
      security for such claim.  The terms and  conditions of any sale under this
      clause (v) shall be determined  in the sole  discretion of the Trustee and
      it shall not be liable to any Person  having an  Ownership  Interest  in a
      Class R Certificate as a result of its exercise of such discretion.

            (vi) If any Person  other than a Permitted  Transferee  acquires any
      Ownership   Interest  in  a  Class  R  Certificate  in  violation  of  the
      restrictions in this Section,  then the Trustee upon receipt of reasonable
      compensation  will provide to the  Internal  Revenue  Service,  and to the
      persons specified in Sections 860E(e)(3) and (6) of the Code,  information
      needed to compute the tax imposed under Section  860E(e)(5) of the Code on
      transfers of residual interests to disqualified organizations.

            (vii) All rights of the Directing  Holder under this Agreement shall
      terminate  immediately upon any transfer of the Class X Certificate to any
      other Person,  unless (i) the Special Servicer  consents in writing to the
      transfer of such  rights and (ii) the  Trustee is  provided  with a letter
      from each Rating  Agency to the effect that the  transfer of the rights of
      the  Directing   Holder  to  such   transferee  will  not  result  in  the
      qualification, withdrawal or downgrade of the ratings then assigned to any
      Class of Certificates.

The  foregoing  provisions  of this  Section  shall cease to apply to  transfers
occurring  on or after the date on which there shall have been  delivered to the
Trustee,  in  form  and  substance  satisfactory  to the  Trustee,  (i)  written
notification  from each Rating  Agency that the removal of the  restrictions  on
Transfer  set  forth in this  Section  will not  cause  such  Rating  Agency  to
downgrade its rating of the  Certificates  and (ii) an Opinion of Counsel to the
effect that such removal  will not cause any REMIC  hereunder to fail to qualify
as a REMIC.

Ladies and Gentlemen:

      In connection  with our  disposition of the above  Certificates we certify
that (a) we understand that the Certificates  have not been registered under the
Securities Act of 1933, as amended (the "Act"),  and are being disposed by us in
a transaction that is exempt from the registration  requirements of the Act, (b)
we have not offered or sold any  Certificates to, or solicited offers to buy any
Certificates  from, any person,  or otherwise  approached or negotiated with any
person with  respect  thereto,  in a manner  that would be deemed,  or taken any
other  action which would result in, a violation of Section 5 of the Act, (c) to
the extent we are disposing of a Class R  Certificate,  we have no knowledge the
Transferee  is not a  Permitted  Transferee  and (d) no purpose of the  proposed
disposition  of a Class R Certificate  is to impede the assessment or collection
of tax.

Distributions.   Following  Receipt  by  Financial  Security  of  a  notice  and
certificate  from  the  Trustee  in the  form  attached  as  Exhibit  A to  this

of Guaranteed  Distributions out of the funds of Financial Security on the later
to occur of (a) 12:00  noon,  New York City  time,  on the second  Business  Day
following  such  Receipt;  and (b)  12:00  noon,  New  York  City  time,  on the
Distribution Date to which such claim relates. Payments due hereunder in respect
of Guaranteed  Distributions  will be disbursed by wire transfer of  immediately
available  funds to the Policy  Payments  Account  established  pursuant  to the
Pooling and Servicing  Agreement or, if no such Policy Payments Account has been
established, to the Trustee.

      Financial  Security  shall be  entitled  to pay any  amount  hereunder  in
respect of Guaranteed Distributions, including any acceleration payment, whether
or not any notice and certificate shall have been Received by Financial Security
as provided  above,  provided,  however,  that by  acceptance of this Policy the
Trustee  agrees to  provide  upon  request  to  Financial  Security a notice and
certificate  in  respect  of any  such  payments  made  by  Financial  Security.
Financial  Security  shall  be  entitled  to  pay  principal   hereunder  on  an
accelerated  basis if Financial  Security shall so elect at its sole discretion,
at any  time  or  from  time  to  time,  in  whole  or in  part,  at an  earlier
distribution date than provided in the definition of "Guaranteed Distributions,"
if such  principal  would have been  payable  under the  Pooling  and  Servicing
Agreement  were funds  sufficient to make such payment  available to the Trustee
for such purpose.  Guaranteed  Distributions insured hereunder shall not include
interest,  in respect of  principal  paid  hereunder  on an  accelerated  basis,
accruing from after the date of such payment of principal.  Financial Security's
obligations hereunder in respect of Guaranteed Distributions shall be discharged
to the extent  funds are  disbursed  by  Financial  Security as provided  herein
whether or not such funds are properly  applied by the  Trustee.

      3.   NOTICES  AND   CONDITIONS   TO  PAYMENT  IN  RESPECT  OF   GUARANTEED
DISTRIBUTIONS AVOIDED AS PREFERENCE PAYMENTS. If any Guaranteed  Distribution is
avoided  as  a  preference  payment  under  applicable  bankruptcy,  insolvency,
receivership or similar law,  Financial Security will pay such amount out of the
funds of  Financial  Security  on the  later of (a) the date when due to be paid
pursuant  to the  Order  referred  to below or (b) the first to occur of (i) the
fourth Business Day following Receipt by Financial  Security from the Trustee of
(A) a certified copy of the order of the court or other  governmental body which
exercised  jurisdiction  to the effect that the  relevant  Holder is required to
return principal or interest distributed with respect to the Certificates during
the Term of this Policy because such  distributions were avoidable as preference
payments under applicable bankruptcy law (the "Order"), (B) a certificate of the
relevant  Holder that the Order has been  entered and is not subject to any stay
and (C) an assignment  duly executed and  delivered by the relevant  Holder,  in
such form as is  reasonably  required by Financial  Security and provided to the
relevant  Holder by  Financial  Security,  irrevocably  assigning  to  Financial
Security  all rights and claims of the Holder  relating to or arising  under the
Certificates  against the debtor which made such preference payment or otherwise
with respect to such preference payment or (ii) the date of Receipt by Financial
Security  from the Trustee of the items  referred to in clauses (A), (B) and (C)
above if, at least four Business  Days prior to such date of Receipt,  Financial
Security  shall have  Received  written  notice from the Trustee that such items
were to be  delivered  on such date and such date was  specified in such notice.
Such   payment    shall   be   disbursed   to   the    receiver,    conservator,
debtor-in-possession  or trustee in bankruptcy named in the Order and not to the
Trustee or any Holder  directly  (unless  such Holder has  previously  paid such
amount  to  the  receiver,  conservator,   debtor-in-possession  or  trustee  in
bankruptcy  named in the Order, in which case such payment shall be disbursed to
the  Trustee  for  distribution  to such  Holder  upon  proof  of  such  payment
reasonably   satisfactory  to  Financial  Security).   In  connection  with  the
foregoing,  Financial  Security  shall  have the  rights  provided  pursuant  to
Sections 11.04(d) and 11.05 of the Pooling and Servicing Agreement.

Security may appoint a fiscal  agent (the  "Fiscal  Agent") for purposes of this
Policy by written notice to the Trustee at the notice  address  specified in the
Pooling and Servicing  Agreement  specifying  the name and notice address of the
Fiscal Agent.  From and after the date of receipt of such notice by the Trustee,
(i) copies of all notices and  documents  required to be  delivered to Financial
Security pursuant to this Policy shall be simultaneously delivered to the Fiscal
Agent and to Financial  Security and shall not be deemed Received until Received

this Policy may be made directly by Financial Security or by the Fiscal Agent on
behalf  of  Financial  Security.  The  Fiscal  Agent is the  agent of  Financial

cause to be deposited,  sufficient funds to make payments due under this Policy.


      6. WAIVER OF DEFENSES.  To the fullest extent permitted by applicable law,
Financial  Security agrees not to assert,  and hereby waives, for the benefit of
each Holder,  all rights  (whether by  counterclaim,  setoff or  otherwise)  and
defenses (including, without limitation, the defense of fraud), whether acquired
by  subrogation,  assignment  or  otherwise,  to the extent that such rights and
defenses  may be  available  to  Financial  Security  to  avoid  payment  of its

Financial Security Assurance Inc.
350 Park Avenue
New York, NY 10022

The  undersigned,  a  duly  authorized  officer  of  Bankers  Trust  Company  of
California,  N.A.  (the  "Trustee"),  hereby  certifies  to  Financial  Security
Assurance Inc.  ("Financial  Security"),  with  reference to Financial  Guaranty
Insurance  Policy No. 50864-N,  dated October 12, 1999 (the "Policy")  issued by
Financial  Security  in respect  of  $233,144,000  United  PanAm  Mortgage  Loan
Asset-Backed  Certificates,   Series  1999-2,  Class  A-1  and  Class  A-2  (the
"Certificates"), that:

(i) The  Trustee is the  Trustee  under the Pooling and
Servicing Agreement for the Holders.

            (ii)  The sum of all  amounts  on  deposit  (or  scheduled  to be on
      deposit) in the Distribution Account and available for distribution to the
      Holders   pursuant  to  the  Pooling  and  Servicing   Agreement  will  be
      $_______________ (the "Shortfall") less than the Guaranteed  Distributions
      with respect to the Distribution Date occurring on _________________.

            (iii)  The  Trustee  is  making a claim  under  the  Policy  for the
      Shortfall to be applied to  distributions of principal or interest or both
      with respect to the Certificates.

            (iv) The  Trustee  agrees  that,  following  receipt  of funds  from
      Financial Security,  it shall (a) hold such amounts in trust and apply the
      same  directly  to  the  payment  of  Guaranteed   Distributions   on  the
      Certificates when due; (b) not apply such funds for any other purpose; (c)
      not  commingle  such funds with other  funds held by the  Trustee  and (d)
      maintain  an  accurate  record  of  such  payments  with  respect  to each
      Certificate and the corresponding claim on the Policy and proceeds thereof
      and, if the  Certificate is required to be  surrendered  for such payment,
      shall  stamp on each such  Certificate  the legend "$  [INSERT  APPLICABLE
      AMOUNT]  paid by  Financial  Security  and the  balance  hereof  has  been
      canceled  and  reissued"  and  then  shall  deliver  such  Certificate  to
      Financial Security.

            (v) The  Trustee,  on  behalf  of the  Holders,  hereby  assigns  to
      Financial  Security  the  rights  of  the  Holders  with  respect  to  the
      Certificates  to the extent of any payments  under the Policy,  including,
      without  limitation,  any  amounts  due  to  the  Holders  in  respect  of
      securities  law  violations  arising  from  the  offer  and  sale  of  the
      Certificates.  The  foregoing  assignment  is in  addition  to, and not in
      limitation  of,  rights of  subrogation  otherwise  available to Financial
      Security in respect of such  payments.  The Trustee shall take such action
      and deliver such instruments as may be reasonably requested or required by
      Financial  Security to effectuate the purpose or provisions of this clause
      (v).

            (vi) The Trustee, on its behalf and on behalf of the Holders, hereby
      appoints Financial Security as agent and  attorney-in-fact for the Trustee
      and  each  such  Holder  in  any  legal  proceeding  with  respect  to the
      Certificates.  The Trustee  hereby  agrees that,  so long as a Certificate
      Insurer Default (as defined in the Pooling and Servicing  Agreement) shall
      not exist,  Financial  Security may at any time during the continuation of
      any  proceeding  by or  against  the  Depositor  under the  United  States
      Bankruptcy   Code  or  any  other   applicable   bankruptcy,   insolvency,
      receivership,  rehabilitation or similar law (an "Insolvency  Proceeding")
      direct all  matters  relating to solvency  Proceeding,  including  without
      limitation,  (A) all matters  relating to any claim in connection  with an
      Insolvency  Proceeding seeking the avoidance as a preferential transfer of
      any payment made with respect to the Certificates (a "Preference  Claim"),
      (B) the direction of any appeal of or relating to any Preference  Claim at
      the expense of Financial Security but subject to reimbursement as provided
      in the Insurance  Agreement and (C) the posting of any surety,  supersedes
      or  performance  bond  pending any such appeal.  In addition,  the Trustee
      hereby agrees that  Financial  Security  shall be  subrogated  to, and the
      Trustee on its behalf and on behalf of each Holder,  hereby  delegates and
      assigns, to the fullest extent permitted by law, the rights of the Trustee
      and each Holder in the conduct of any  Insolvency  Proceeding,  including,
      without limitation,  all rights of any party to an adversary proceeding or
      action with respect to any court order issued in connection  with any such
      Insolvency Proceeding.

            (vii)  Payment  should be made by wire  transfer  directed to Policy
      Payments Account.
