                  -------------------------------------------

                           -----------------------------------------------------
                           Files.
                           ------

     The Seller,   simultaneously   with the payment of the Purchase Price,   shall
execute and deliver to the Initial   Purchaser an Assignment and Conveyance   with
respect to the related   Mortgage   Loan   Package in the form   attached   hereto as
Exhibit 4. The   Servicing   File   retained by the   Servicer   with respect to each
Mortgage Loan pursuant to this Agreement   shall be   appropriately   identified in
the   Servicer's   computer   system to reflect   clearly   the sale of such   related
Mortgage Loan to the Purchaser.   The Purchaser   shall be entitled to receive all
Prepayment   Charges   required to be paid by a   Mortgagor   under the terms of any
Mortgage   Loan.   The Servicer shall release from its custody the contents of any
Servicing   File retained by it only in accordance   with this   Agreement,   except
when such   release is   required   in   connection   with a   repurchase   of any such

          Subsection 6.02. Books and Records.
                           -----------------

     Record   title to each   Mortgage   and the   related   Mortgage   Note as of the
related   Closing   Date shall be in the name of the   Seller,   the   Servicer,   the
Purchaser,   the   Custodian   or one or more   designees of the   Purchaser,   as the
Purchaser shall designate.   Notwithstanding the foregoing,   beneficial ownership
of each   Mortgage and the related   Mortgage   Note shall be vested   solely in the
Purchaser or the appropriate designee of the Purchaser,   as the case may be. All
rights   arising out of the   Mortgage   Loans   including,   but not limited to, all
funds received by the Seller after the related   Cut-off Date on or in connection
with a Mortgage   Loan as provided in Section 4 shall be vested in the   Purchaser
or one or more   designees of the   Purchaser;   provided,   however,   that all such
funds received on or in connection with a Mortgage Loan as provided in Section 4
shall   be   received   and held by the   Seller   in trust   for the   benefit   of the
Purchaser or the assignee of the Purchaser,   as the case may be, as the owner of
the Mortgage Loans pursuant to the terms of this Agreement.

     It   is   the   express    intention   of   the   parties   that   the   transactions
contemplated   by this   Agreement be, and be construed as, a sale of the Mortgage
Loans by the Seller and not a pledge of the Mortgage   Loans by the Seller to the
Purchaser to secure a debt or other obligation of the Seller. Consequently,   the
sale of each Mortgage Loan shall be reflected as a sale on the Seller's business
records, tax returns and financial statements.

          Subsection 6.03.   Delivery of Mortgage Loan Documents.
                            -----------------------------------

      The   Seller   or   Servicer,   as   applicable,   shall   from   time   to   time in
connection with each Closing Date, at least five (5) Business Days prior to such
Closing Date, deliver and release to the Custodian those Mortgage Loan Documents
set   forth on   Exhibit   13   hereto   with   respect   to each   Mortgage   Loan to be

                                       15

<PAGE>

purchased   and sold on the   related   Closing   Date and set forth on the   related
Mortgage Loan Schedule delivered with such Mortgage Loan Documents.

     The Servicer   shall   provide to each of the   Purchaser   and the Custodian a
notice containing a list of authorized   servicing officers (each, an "Authorized
Representative")   for the purpose of giving and receiving notices,   requests and
instructions   and delivering   certificates and documents in connection with this
Agreement.   Such notice shall contain the specimen signature for each Authorized
Representative. From time to time, the Servicer may, by delivering to the others
a revised   notice,   change the   information   previously   given   pursuant to this
Section,   but each of the parties hereto shall be entitled to rely   conclusively
on the then current notice until receipt of a superseding notice.

     The Custodian shall certify its receipt of all such Mortgage Loan Documents
required to be   delivered   pursuant to this   Agreement   for the related   Closing
Date,   as   evidenced   by the Trust   Receipt   and   Initial   Certification   of the
Custodian in the form annexed to the Custodial Agreement.   The Servicer shall be
responsible for maintaining   the Custodial   Agreement.   The fees and expenses of
the Custodian shall be paid by the Seller.

     The Seller 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 Seller 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   one
hundred twenty (120) days of its submission   for   recordation.   If such document
has not been   received   after such 120 day period,   the Seller shall   deliver an
officer's   certificate   to the   Purchaser   certifying   that such failure was due
solely to (i) the   failure of the   applicable   recorder's   office to return such
document   sent for   recording or (ii) the failure of the title   insurer to issue
and deliver the original   mortgagee   title   policy;   provided that in any event,
Seller shall cause such document to be delivered to Purchaser   within six months
of its submission for   recordation or at the   Purchaser's   option,   Seller shall
repurchase such Mortgage Loan from the Purchaser within two (2) Business Days of
request at the Repurchase Price.

          Subsection 6.04    Quality Control Procedures.
                            ---------------------------

     The Seller shall have an internal quality control program that verifies, on
a regular   basis,   the   existence   and accuracy of the legal   documents,   credit
documents,   property appraisals,   and underwriting decisions.   The program shall
include   evaluating   and   monitoring   the overall   quality of the Seller's   loan
production and the servicing   activities of the Seller. The program is to ensure
that the Mortgage Loans are originated and serviced in accordance   with Accepted
Servicing   Standards and the Underwriting   Guidelines;   guard against dishonest,
fraudulent,   or   negligent   acts;   and guard   against   errors and   omissions   by
officers, employees, or other authorized persons.

     solicited   or   knowingly   received   any advance of funds from a party other
     than the owner of the related Mortgaged   Property,   directly or indirectly,
     for the payment of any amount required by the Mortgage Note or Mortgage; no
     Mortgage Loan is thirty (30) or more days delinquent as of the Closing Date


                                       19

      and there has been no delinquency, exclusive of any period of grace, in any
     payment by the Mortgagor   thereunder   since the origination of the Mortgage
     Loan;

          (iv) There are no delinquent taxes, ground rents, water charges, sewer
     rents,   assessments,   insurance   premiums,   leasehold   payments,   including
     assessments   payable in future   installments or other   outstanding   charges
     affecting the related Mortgaged Property;

          (v) The   terms of the   Mortgage   Note and the   Mortgage   have not been
     impaired,   waived,   altered or modified in any   respect,   except by written
     instruments,    recorded   in   the   applicable   public   recording   office   if
     necessary to maintain   the lien   priority of the   Mortgage,   and which have
     been   delivered   to   the   Custodian;   the   substance   of any   such   waiver,
     alteration   or   modification   has been   approved by the   insurer   under the
     Primary   Insurance   Policy,   if any,   and has been   approved   by the   title
     insurer,   to the extent required by the related policy, and is reflected on
     the related Mortgage Loan Schedule. No instrument of waiver,   alteration or
     modification   has been   executed,   and no Mortgagor has been   released,   in
     whole   or in   part,   except   in   connection   with an   assumption   agreement
     approved by the insurer under the Primary   Insurance Policy, if any, and by
     the   title   insurer,   to the   extent   required   by the   policy,   and   which
     assumption   agreement has been   delivered to the Custodian and the terms of
     which are reflected in the related Mortgage Loan Schedule;

          (vi) The   Mortgage   Note and the Mortgage are not subject to any right
     of rescission,   set-off,   counterclaim or defense, including the defense of
     usury,   nor will the operation of any of the terms of the Mortgage Note and

     unenforceable,   in whole or in part, or subject to any right of rescission,
     set-off,   counterclaim   or defense,   including   the defense of usury and no
     such   right   of   rescission,   set-off,   counterclaim   or   defense   has been
     asserted   with   respect   thereto.   Each   Prepayment   Charge or penalty with

     replacement cost of all improvements to the Mortgaged Property, (ii) either
     (A) the outstanding   principal balance of the Mortgage Loan with respect to
     each first lien   Mortgage   Loan or (B) with   respect   to each   second   lien
     Mortgage Loan, the sum of the outstanding   principal balance of the related
     first   lien   mortgage   loan and the   outstanding   principal   balance of the

     Property,   and consistent   with the amount that would have been required as
     of the date of origination in accordance with the Underwriting   Guidelines,
     or (iv) 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.   All such insurance   policies   contain a standard   mortgagee   clause
     naming the   Servicer,   its   successors   and   assigns as   mortgagee   and all
     premiums   thereon have been paid. If the   Mortgaged   Property is in an area

                                       20


<PAGE>

     identified on a Flood Hazard Map or Flood   Insurance Rate Map issued by the
     Federal   Emergency   Management   Agency as having special flood hazards (and
     such flood   insurance   has been made   available) a flood   insurance   policy
     meeting the requirements of the current guidelines of the Federal Insurance
     Administration   is in effect which policy   conforms to the   requirements of
     FNMA an FHLMC. The Mortgage obligates the Mortgagor   thereunder to maintain
     all   such   insurance   at   the   Mortgagor's   cost   and   expense,   and on the
     Mortgagor's   failure to do so,   authorizes   the holder of the   Mortgage   to
     maintain   such   insurance   at   Mortgagor's   cost   and   expense   and to seek
     reimbursement therefor from the Mortgagor;

          (viii) Any and all   requirements   of any   federal,   state or local law
     including,   without   limitation,   usury,   truth   in   lending,   real   estate
     settlement   procedures,   predatory   and abusive   lending,   consumer   credit
     protection,   equal   credit   opportunity,   fair housing or   disclosure   laws
     applicable to the   origination   and   servicing of mortgage   loans of a type
     similar to the   Mortgage   Loans and   applicable   to any   Prepayment   Charge
     associated with the Mortgage Loans at origination have been complied with;

          (ix) The Mortgage has not been satisfied,   cancelled,   subordinated or
     rescinded,   in whole or in part,   and the   Mortgaged   Property has not been
     released   from the lien of the Mortgage,   in whole or in part,   nor has any
     instrument    been   executed   that   would   effect   any   such    satisfaction,
     cancellation, subordination, rescission or release;

          (x) The Mortgage (including any Negative   Amortization which may arise
     thereunder) is a valid,   existing and   enforceable (A) first lien and first
     priority   security   interest   with respect to each   Mortgage   Loan which is
     indicated   by the Seller to be a first lien (as   reflected   on the Mortgage
     Loan Schedule),   or (B) second lien and second priority   security   interest
     with respect to each Mortgage Loan which is indicated by the Seller to be a
     second lien (as reflected on the Mortgage Loan   Schedule),   in either case,
     on the   Mortgaged   Property,   including all   improvements   on the Mortgaged
     Property   subject only to (a) the lien of current real   property   taxes and
     assessments   not   yet   due   and   payable,   (b)   covenants,   conditions   and
     restrictions,   rights of way,   easements   and other   matters   of the public
      record as of the date of recording   being   acceptable   to mortgage   lending
     institutions   generally and specifically   referred to in the lender's title
     insurance policy delivered to the originator of the Mortgage Loan and which
     do not adversely affect the Appraised Value of the Mortgaged Property,   (c)
     with respect to each Mortgage Loan which is indicated by the Seller to be a
     second lien Mortgage   Loan (as   reflected on the Mortgage Loan   Schedule) a
     first lien on the Mortgaged   Property;   and (d) other matters to which like
     properties are commonly subject which do not materially   interfere with the
     benefits of the   security   intended   to be provided by the   Mortgage or the
     use,   enjoyment,   value or marketability of the related Mortgaged Property.
     Any security agreement,   chattel mortgage or equivalent document related to
     and delivered in connection with the Mortgage Loan   establishes and creates
     a valid,   existing and enforceable first or second lien and first or second
     priority security interest (in each case, as indicated on the Mortgage Loan
     Schedule) on the property   described   therein and the Seller has full right
     to sell and assign the same to the   Purchaser.   The Mortgaged   Property was
     not,   as of the date of   origination   of the   Mortgage   Loan,   subject to a
     mortgage,   deed of trust, deed to secure debt or other security   instrument
     creating a lien subordinate to the lien of the Mortgage;


                                        21

<PAGE>

          (xi) The Mortgage   Note and the related   Mortgage are genuine and each
     is   the   legal,    valid   and   binding   obligation   of   the   maker   thereof,
     enforceable in accordance with its terms;

          (xii) All   parties to the   Mortgage   Note and the   Mortgage   had legal
     capacity   to enter into the   Mortgage   Loan and to execute   and deliver the
     Mortgage Note and the Mortgage, and the Mortgage Note and the Mortgage have
     been duly and properly executed by such parties. The Mortgagor is a natural
     person;   (xiii) The proceeds of the Mortgage Loan have been fully disbursed
     to or for the account of the Mortgagor   and there is no obligation   for the
     Mortgagee   to   advance    additional    funds   thereunder   and   any   and   all
     requirements as to completion of any on-site or off-site improvement and as
     to   disbursements of any escrow funds therefor have been complied with. All
     costs,   fees and expenses   incurred in making or closing the Mortgage   Loan
     and the recording of the Mortgage have been paid,   and the Mortgagor is not
     entitled to any refund of any amounts paid or due to the Mortgagee pursuant
     to the Mortgage Note or Mortgage;

          (xiv) The Seller is the sole legal,   beneficial and equitable owner of
     the Mortgage   Note and the Mortgage and has full right to transfer and sell
     the   Mortgage   Loan to the   Purchaser   free and   clear of any   encumbrance,
     equity, lien, pledge, charge, claim or security interest;

          (xv) All parties   which have had any   interest in the   Mortgage   Loan,
     whether as mortgagee,   assignee,   pledgee or otherwise, are (or, during the
     period   in   which   they   held   and   disposed   of such   interest,   were)   in
     compliance   with any and all   applicable   "doing   business"   and   licensing
     requirements   of the laws of the state   wherein the   Mortgaged   Property is
     located;

          (xvi) Each first lien Mortgage Loan and second lien Mortgage Loan that
     is originated in   conjunction   with the related first lien Mortgage Loan is
     covered by an   American   Land Title   Association   ("ALTA")   lender's   title
     insurance   policy (which,   in the case of an Adjustable   Rate Mortgage Loan
     has an adjustable rate mortgage endorsement in the form of ALTA 6.0 or 6.1)
     acceptable   to   Fannie   Mae and   Freddie   Mac,   issued   by a title   insurer
     acceptable   to Fannie Mae and Freddie Mac and   qualified   to do business in
     the jurisdiction where the Mortgaged Property is located, insuring (subject
     to the   exceptions   contained   in (x)(a) and (b),   and with   respect to any
     second lien   Mortgage   Loan (c),   above) the   Seller,   its   successors   and
     assigns   as to the   first or   second   priority   lien (as   indicated   on the
     Mortgage Loan Schedule) of the Mortgage in the original principal amount of
     the Mortgage   Loan   (including,   if the Mortgage Loan provides for Negative
     Amortization,   the maximum   amount of Negative   Amortization   in accordance
     with the Mortgage) and, with respect to any Adjustable   Rate Mortgage Loan,
     against any loss by reason of the   invalidity   or   unenforceability   of the
     lien resulting from the provisions of the Mortgage providing for adjustment
     in the Mortgage Interest Rate and Monthly Payment and Negative Amortization
     provisions   of   the   Mortgage   Note.   Additionally,    such   lender's   title
     insurance policy   affirmatively   insures ingress and egress to and from the
     Mortgaged   Property,   and against   encroachments   by or upon the   Mortgaged
     Property or any   interest   therein.   The Seller is the sole insured of such


                                       22

<PAGE>

     lender's title insurance   policy,   and such lender's title insurance policy
     is in full force and   effect and will be in full force and effect   upon the
     consummation of the transactions   contemplated by this Agreement. No claims
     have been made under such lender's   title   insurance   policy,   and no prior
     holder of the related Mortgage,   including the Seller,   has done, by act or
     omission,   anything   which would impair the coverage of such lender's title
     insurance policy. Each second lien Mortgage Loan that was not originated in
     conjunction   with the   related   first lien   Mortgage   Loan is covered by an
     Alternative Title Product.

          (xvii) There is no default, breach, violation or event of acceleration
     existing   under the Mortgage or the Mortgage Note and no event which,   with
     the passage of time or with notice and the   expiration of any grace or cure
     period,   would   constitute   a   default,    breach,   violation   or   event   of
     acceleration,   and the Seller has not waived any default, breach, violation
     or event of   acceleration.   With respect to each second lien   Mortgage Loan
     (i) the first lien mortgage loan is in full force and effect, (ii) there is
     no default,   breach, violation or event of acceleration existing under such
     first lien   mortgage or the related   mortgage   note,   (iii) no event which,
     with the passage of time or with notice and the   expiration of any grace or
     cure   period,   would   constitute a default,   breach,   violation or event of
     acceleration thereunder, (iv) either (A) the first lien mortgage contains a
     provision which allows or (B) applicable law requires,   the mortgagee under
     the second   lien   Mortgage   Loan to receive   notice   of, and   affords   such
     mortgagee   an   opportunity   to   cure   any   default   by   payment   in full or
     otherwise   under the first lien   mortgage,   (v) the related first lien does
     not   provide   for or permit   negative   amortization   under   such first lien
     Mortgage Loan, and (vi) either no consent for the Mortgage Loan is required
     by the holder of the first lien or such   consent has been   obtained   and is
     contained in the Mortgage File;

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

          (xix) All   improvements   which   were   considered   in   determining   the
     Appraised   Value of the related   Mortgaged   Property lay wholly   within the
     boundaries and building restriction lines of the Mortgaged Property, and no
     improvements on adjoining   properties encroach upon the Mortgaged Property.
     No   improvement   located on or being part of the   Mortgaged   Property is in
     violation of any applicable   zoning law or regulation,   subdivision   law or
     ordinance;

          (xx) The   Mortgage   Loan was   originated   by the   Seller,   a Qualified
     Correspondent   or by a savings   and loan   association,   a savings   bank,   a
     commercial   bank or similar   banking   institution   which is supervised   and
     examined by a federal or state   authority,   or by a   mortgagee   approved as
     such by the Secretary of HUD;

          (xxi)   Principal   payments on the Mortgage Loan commenced no more than
     sixty (60) days after the proceeds of the Mortgage Loan were disbursed. The
     Mortgage Loan bears interest at the Mortgage Interest Rate. With respect to
     each Mortgage Loan which is not a Negative   Amortization Loan, the Mortgage
     Note is payable on the first day of each month in Monthly Payments,   which,


                                       23

<PAGE>

     in the case of a Fixed Rate Mortgage Loan, are sufficient to fully amortize
     the original   principal   balance over the original term thereof (other than
     with respect to a Mortgage   Loan   identified   on the related   Mortgage Loan
     Schedule as an interest-only   Mortgage Loan during the interest-only period
     or a   Mortgage   Loan   which is   identified   on the   related   Mortgage   Loan
     Schedule   as a Balloon   Mortgage   Loan) and to pay   interest at the related
     Mortgage   Interest   Rate,   and, in the case of an Adjustable   Rate Mortgage
     Loan, are changed on each Adjustment   Date, and in any case, are sufficient
     to fully   amortize the original   principal   balance over the original   term
     thereof   (other   than with   respect to a Mortgage   Loan   identified   on the
     related Mortgage Loan Schedule as an interest-only Mortgage Loan during the
     interest-only   period or a Mortgage Loan which is identified on the related
     Mortgage Loan Schedule as a Balloon   Mortgage   Loan) and to pay interest at
     the   related   Mortgage    Interest   Rate.   With   respect   to   each   Negative
     Amortization   Mortgage Loan,   the related   Mortgage Note requires a Monthly
     Payment   which is   sufficient   during the   period   following   each   Payment
     Adjustment Date, to fully amortize the outstanding   principal balance as of
     the first day of such period (including any Negative Amortization) over the
     then   remaining   term of such   Mortgage   Note   and to pay   interest   at the
     related Mortgage   Interest Rate;   provided,   that the Monthly Payment shall
     not increase to an amount that exceeds   107.5% of the amount of the Monthly
     Payment   that was due   immediately   prior to the Payment   Adjustment   Date;
     provided,   further, that the payment adjustment cap shall not be applicable
     with respect to the adjustment made to the Monthly Payment that occurs in a
     year in which the Mortgage Loan has been outstanding for a multiple of five
     (5) years and in any such year the   Monthly   Payment   shall be   adjusted to
     fully amortize the Mortgage Loan over the remaining   term.   With respect to
     each   Mortgage   Loan   identified   on   the   Mortgage   Loan   Schedule   as   an
     interest-only   Mortgage Loan, the interest-only period shall not exceed ten
     (10) years (or such other period   specified on the Mortgage Loan   Schedule)
     and following the expiration of such   interest-only   period,   the remaining
     Monthly   Payments   shall be   sufficient   to   fully   amortize   the   original
     principal   balance over the remaining   term of the Mortgage Loan and to pay
     interest   at the   related   Mortgage   Interest   Rate.   With   respect to each
     Balloon   Mortgage Loan, the Mortgage Note requires a monthly   payment which
     is sufficient   to fully   amortize the original   principal   balance over the
     original term thereof and to pay interest at the related Mortgage   Interest
     Rate and requires a final Monthly   Payment   substantially   greater than the
     preceding monthly payment which is sufficient to repay the remaining unpaid
     principal   balance   of the   Balloon   Mortgage   Loan at the Due Date of such
     monthly payment. The Index for each Adjustable Rate Mortgage Loan is as set
     forth on the Mortgage   Loan   Schedule.   No Mortgage   Loan is a   Convertible
     Mortgage Loan. No Balloon   Mortgage Loan has an original stated maturity of
     less than seven (7) years;

          (xxii) The origination,   servicing and collection   practices used with
     respect to each Mortgage Note and Mortgage   including,   without limitation,
     the   establishment,   maintenance   and servicing of the Escrow   Accounts and
      Escrow   Payments,   if any,   since   origination,   have been in all   respects
     legal,   proper,   prudent and   customary   in the   mortgage   origination   and

     of the benefits of the security   provided   thereby,   including,   (a) in the
     case of a Mortgage   designated as a deed of trust,   by trustee's   sale, and
     (b) otherwise by judicial foreclosure.   The Mortgaged Property has not been
     subject to any   bankruptcy   proceeding or   foreclosure   proceeding   and the
     Mortgagor has not filed for protection   under   applicable   bankruptcy laws.
     There is no homestead or other   exemption   available to the Mortgagor which
     would   interfere   with   the   right   to sell   the   Mortgaged   Property   at a
     trustee's   sale or the right to foreclose the   Mortgage.   The Mortgagor has
     not   notified   the Seller and the   Seller   has no   knowledge   of any relief
     requested   or   allowed to the   Mortgagor   under the   Servicemembers'   Civil
     Relief Act;

          (xxv)   The   Mortgage   Loan was   underwritten   in   accordance   with the

     loan made on the security   thereof,   whose   compensation is not affected by
     the approval or   disapproval   of the Mortgage   Loan and who met the minimum
     qualifications   of FNMA and FHLMC.   Each appraisal of the Mortgage Loan was
     made   in   accordance    with   the   relevant    provisions   of   the   Financial
     Institutions Reform, Recovery, and Enforcement Act of 1989;

          (xxviii)   In the event the   Mortgage   constitutes   a deed of trust,   a
     trustee,   duly   qualified   under   applicable law to serve as such, has been
     properly   designated   and currently so serves and is named in the Mortgage,
     and no fees or expenses are or will become   payable by the Purchaser to the

     with respect to the Mortgage,   the Mortgaged Property, the Mortgagor or the
     Mortgagor's   credit   standing that can   reasonably be expected to cause the
     Mortgage Loan to be an unacceptable investment,   or cause the Mortgage Loan
     to become delinquent or adversely affect the value of the Mortgage Loan;

          (xxxiii) No Mortgage Loan had an LTV or CLTV at   origination in excess
     of 100%.   Each Mortgage Loan with an LTV at origination in excess of 80% is

     Insurer,   which   insures that portion of the Mortgage Loan in excess of the
     portion of the   Appraised   Value of the   Mortgaged   Property as required by
     Fannie   Mae.   With   respect   to any   Mortgage   Loan which   allows   Negative
     Amortization,   such Primary   Insurance Policy contains   provisions to cover
     the potential   Negative   Amortization of such Mortgage Loan. All provisions
     of such Primary   Insurance   Policy have been and are being   complied   with,
     such policy is in full force and effect,   and all premiums   due   thereunder
     have been paid. Any Mortgage   subject to any such Primary   Insurance Policy
     obligates   the Mortgagor   thereunder to maintain such   insurance and to pay
     all premiums and charges in   connection   therewith.   The Mortgage   Interest
      Rate for the Mortgage Loan does not include any such insurance premium.   No
     Mortgage   Loan is   subject   to a lender   paid   primary   mortgage   insurance
     policy;

          (xxxiv) The Mortgaged   Property is lawfully   occupied under applicable
      law;   all   inspections,   licenses and   certificates   required to be made or

     limited to certificates   of occupancy,   have been made or obtained from the
     appropriate authorities;

          (xxxv) No error,   omission,   misrepresentation,   negligence,   fraud or

     Cut-off Date have been consolidated   with the outstanding   principal amount
     secured by the Mortgage, and the secured principal amount, as consolidated,

     Mortgage securing the consolidated principal amount is expressly insured as
     having first or second (as   indicated on the Mortgage Loan   Schedule)   lien
     priority by a title insurance policy, an endorsement to the policy insuring
     the mortgagee's consolidated interest or by other title evidence acceptable
     to FNMA or FHLMC.   The   consolidated   principal   amount does not exceed the
     original    principal    amount   of   the   Mortgage   Loan   plus   any   Negative
     Amortization;

          (xxxviii) If the Residential   Dwelling on the Mortgaged   Property is a
     condominium unit or a unit in a planned unit   development   (other than a de

     violation of such law;

          (xlii) The Seller shall, at its own expense, cause each Mortgage to be
     covered by a Tax Service   Contract   which is assignable to the Purchaser or
     its designee;   provided however,   that if the Seller fails to purchase such

     connection with the purchase of any such Tax Service Contract;

          (xliii) Each Mortgage Loan is covered by a Flood Zone Service Contract

     Loan or Covered   Loan,   as   applicable   (as such   terms are   defined in the
     current Standard & Poor's LEVELS(R) Glossary Revised, Appendix E);

          (xlv) No predatory, abusive, or deceptive lending practices, including
     but not limited to, the extension of credit to a Mortgagor   without   regard
     for the Mortgagor's ability to repay the Mortgage Loan and the extension of
     credit to a Mortgagor which has no apparent benefit to the Mortgagor,   were
     employed in connection   with the   origination   of the Mortgage   Loan.   Each
     Mortgage Loan is in compliance with the anti-predatory   lending eligibility

     obtaining the extension of credit.   No Mortgagor   obtained a prepaid single
     premium   credit   insurance   policy   (e.g.,   life,    mortgage,    disability,
     accident,   unemployment or health insurance   product) or debt   cancellation
     agreement in   connection   with the   origination   of the Mortgage   Loan.   No
     proceeds from any Mortgage Loan were used to purchase single premium credit
     insurance   policies   or   debt   cancellation    agreements   as   part   of   the
      origination of, or as a condition to closing, such Mortgage Loan;

          (xlviii) The Mortgage   Loans were not   selected   from the   outstanding
     one- to four-family   mortgage   loans in the Seller's   portfolio as to which
     the   representations   and warranties   set forth in this Agreement   could be
     made at the related Closing Date in a manner so as to affect   adversely the
     interests of the Purchaser;

          (xlix)   The   Mortgage   contains   an   enforceable    provision   for   the
      acceleration of the payment of the unpaid principal balance of the Mortgage
     Loan in the   event   that   the   Mortgaged   Property   is sold or   transferred
     without the prior written consent of the mortgagee thereunder;

          (l) The Mortgage   Loan complies with all   applicable   consumer   credit

     property or mixed use property;

          (liv) Each Mortgage Loan is eligible for sale in the secondary   market
     or for inclusion in a Pass-Through   Transaction without unreasonable credit
     enhancement;

           (lv) Except as set forth on the related   Mortgage Loan Schedule,   none
     of the Mortgage Loans are subject to a Prepayment   Charge.   With respect to
     any Mortgage   Loan that   contains a provision   permitting   imposition   of a
     premium upon a prepayment prior to maturity: (a) the Mortgage Loan provides
     some benefit to the   Mortgagor   (e.g. a rate or fee   reduction) in exchange
     for   accepting   such   Prepayment   Charge;   (b) the   Prepayment   Charge   was
     adequately   disclosed to the   Mortgagor   pursuant to   applicable   state and
     federal   law;   and (c) such   Prepayment   Charge shall not be imposed in any
     instance   where the Mortgage Loan is   accelerated or paid off in connection
     with   the   workout   of a   delinquent   Mortgage   or due   to the   Mortgagor's
     default,   notwithstanding   that the terms of the Mortgage   Loan or state or
     federal law might permit the imposition of such Prepayment Charge;

          (lvi)   The   Seller   has   complied   with   all    applicable    anti-money
     laundering   laws and   regulations,   including   without   limitation   the USA
     Patriot Act of 2001 (collectively,   the "Anti-Money   Laundering Laws"); the
     Seller has   established   an   anti-money   laundering   compliance   program as
     required by the Anti-Money Laundering Laws, has conducted the requisite due
     diligence in   connection   with the   origination   of each   Mortgage Loan for
     purposes of the Anti-Money   Laundering Laws,   including with respect to the
     legitimacy of the applicable Mortgagor and the origin of the assets used by
     the said Mortgagor to purchase the Mortgaged Property,   and maintains,   and
     will maintain,   sufficient information to identify the applicable Mortgagor
     for purposes of the Anti-Money Laundering Laws. No Mortgage Loan is subject
     to nullification   pursuant to Executive Order 13224 (the "Executive Order")
     or the   regulations   promulgated by the Office of Foreign Assets Control of
     the United States Department of the Treasury (the "OFAC Regulations") or in
     violation of the Executive Order or the OFAC Regulations,   and no Mortgagor
     is   subject   to   the   provisions   of   such   Executive   Order   or   the   OFAC
     Regulations   nor   listed as a "blocked   person"   for   purposes   of the OFAC
     Regulations;

          (lvii) No Mortgagor   was   encouraged   or required to select a Mortgage
     Loan product   offered by the Mortgage Loan's   originator   which is a higher
     cost product designed for less creditworthy   borrowers,   unless at the time
     of the Mortgage Loan's   origination,   such Mortgagor did not qualify taking
     into   account   credit   history   and debt to income   ratios for a lower cost
     credit   product   then   offered by the   Mortgage   Loan's   originator   or any
     affiliate of the Mortgage Loan's originator;

          (lviii) The methodology   used in underwriting   the extension of credit
     for each   Mortgage Loan employs   objective   mathematical   principles   which
     relate the Mortgagor's income, assets, liabilities and/or credit history to
     the proposed payment and such underwriting methodology does not rely on the
     extent   of the   Mortgagor's   equity   in   the   collateral   as the   principal


                                        29

<PAGE>

     determining   factor in approving such credit   extension.   Such underwriting
     methodology      confirmed     that     at     the     time     of     origination
     (application/approval)   the   Mortgagor   had a   reasonable   ability   to make
     timely payments on the Mortgage Loan;

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

     each Mortgage Loan pursuant to Fannie Mae Guide   Announcement 95-19 and for
     each   Mortgage   Loan,   Seller   agrees it shall report one of the   following
     statuses each month as follows: new origination,   current, delinquent (30-,
     60-, 90-days, etc.), foreclosed, or charged-off;

          (lxii)   With   respect   to   any   Mortgage   Loan   which   is   secured   by
     manufactured housing, if such Mortgage Loans are permitted hereunder,   such
     Mortgage Loan   satisfies   the   requirements   for   inclusion in   residential
     mortgage backed securities   transactions rated by Standard & Poor's Ratings
     Services and such manufactured   housing will be the principal   residence of
     the Mortgagor upon the   origination   of the Mortgage Loan.   With respect to
     any   second   lien   Mortgage   Loan,   such   lien is on a one- to   four-family
     residence   that is (or will be) the   principal   residence of the   Mortgagor
     upon the origination of the second lien Mortgage Loan;

          (lxiii) Each Mortgage Loan   constitutes a "qualified   mortgage"   under

     or such consent has been   obtained   and is contained in the Mortgage   File;
     and

          (lxxxiii) No Mortgagor   agreed to submit to arbitration to resolve any
     dispute   arising   out of or   relating   in any   way   to   the   Mortgage   Loan
     transaction.


                                       32

<PAGE>

          (lxxxiv) No Mortgage Loan is subject to mandatory arbitration;

          (lxxxv) No Mortgage Loan is secured by a lien on a "condo hotel;"

          (lxxxvi) The   Mortgaged   Property   consists of a contiguous   parcel of
     real property with a detached single family residence erected thereon, or a
     two-to   four-family   dwelling,   or   an   individual   condominium   unit   in a
     condominium   project,   or an individual unit in a planned unit development.
     None of the Mortgaged   Properties are manufactured homes, log homes, mobile
     homes,   geodesic   domes or other unique   property   types.   No Mortgage Loan
     finances builder inventory.

          (lxxxvii) If the Mortgage   Loan is secured by a long-term   residential
     lease,   (i) the lessor   under the lease holds a fee simple   interest in the
     land; (ii) the terms of such lease   expressly   permit the mortgaging of the
     leasehold estate,   the assignment of the lease without the lessor's consent
     and the   acquisition   by the   holder of the   Mortgage   of the rights of the
     lessee upon foreclosure or assignment in lieu of foreclosure or provide the
     holder of the Mortgage with substantially   similar   protections;   (iii) the
     terms of such   lease do not (A)   allow   the   termination   thereof   upon the
     lessee's   default   without   the holder of the   Mortgage   being   entitled to
     receive written notice of, and opportunity to cure, such default, (B) allow
      the   termination of the lease in the event of damage or destruction as long

     any increase in the rent other than pre-established   increases set forth in
     the lease, (E) the original term of such lease is not less than the term of
     the related Mortgage; (F) the term of such lease does not terminate earlier
     than five years after the maturity date of the Mortgage   Note,   and (G) the
     Mortgaged   Property   is   located   in a   jurisdiction   in   which   the use of
     leasehold estates in transferring   ownership in residential properties is a
     widely accepted practice.

          (lxxxviii) All of the terms of the related Mortgage Note pertaining to
     interest    adjustments,    payment    adjustments    and   adjustments   of   the
     outstanding principal balance, if any, are enforceable and such adjustments
     on such Mortgage   Loan have been made   properly and in accordance   with the
     provisions of such Mortgage Loan,   including any required notices, and such
     adjustments do not and will not affect the priority of the Mortgage lien.

          (lxxxix) For each fixed-rate   Mortgage Loan, the Mortgage   contains an
     enforceable   provision,   to the extent not   prohibited by federal law as of
     the date of such   Mortgage,   for the   acceleration   of the   payment   of the
     unpaid   principal   balance   of the   Mortgage   Loan in the   event   that   the
     Mortgaged Property is sold or transferred without the prior written consent
     of the mortgagee thereunder.

       Subsection 7.03.    Remedies for Breach of Representations and Warranties.
                          ------------------------------------------------------

     It is understood   and agreed that the   representations   and   warranties set
forth in Subsections   7.01 and 7.02 shall survive the sale of the Mortgage Loans
to   the    Purchaser    and   shall   inure   to   the    benefit   of   the    Purchaser,
notwithstanding any restrictive or qualified endorsement on any Mortgage Note or
Assignment of Mortgage or the examination or lack of examination of any Mortgage


                                       33

<PAGE>

File.   Upon   discovery   by the   Seller   of a   breach   of   any   of the   foregoing
representations   and warranties which materially and adversely affects the value
of the Mortgage Loans or the interest of the Purchaser (or which   materially and
adversely affects the value of a Mortgage Loan or the interests of the Purchaser
in the   related   Mortgage   Loan in the   case of a   representation   and   warranty
relating to a   particular   Mortgage   Loan),   or in the event that any   Mortgagor
fails to make the first payment due to the Purchaser following the Closing Date,
the Seller shall give prompt written notice to the Purchaser.

     Within sixty (60) days of the earlier of either discovery by the Seller, or
notice to the   Seller,   of any   breach of a   representation   or   warranty   which
materially   and   adversely   affects the value of a Mortgage Loan or the Mortgage
Loans or the Purchaser's   interest in a Mortgage Loan or the Mortgage Loans, the
Seller shall use its best   efforts   promptly to cure such breach in all material
respects   and,   if such   breach   cannot   be   cured,   the   Seller   shall,   at the
Purchaser's   option,   repurchase such Mortgage Loan at the Repurchase   Price. In
the event that a breach shall involve any   representation   or warranty set forth
in Subsection 7.01 and such breach cannot be cured within 60 days of the earlier
of   either   discovery   by or notice to the   Seller   of such   breach,   all of the
Mortgage Loans shall, at the Purchaser's option, be repurchased by the Seller at
the   Repurchase   Price.   The Seller   shall,   at the request of the Purchaser and
assuming   that   Seller has a Qualified   Substitute   Mortgage   Loan,   rather than
repurchase   the Mortgage Loan as provided   above,   remove such Mortgage Loan and
substitute in its place a Qualified Substitute Mortgage Loan or Loans;   provided
that such   substitution   shall be   effected   not later   than 120 days   after the
related Closing Date. If the Seller has no Qualified   Substitute   Mortgage Loan,
it shall   repurchase   the deficient   Mortgage Loan. Any repurchase of a Mortgage
Loan(s) pursuant to the foregoing provisions of this Subsection 7.03 shall occur
on a date   designated by the Purchaser and shall be   accomplished   by deposit in
the Custodial   Account of the amount of the Repurchase Price for distribution to
the Purchaser on the next scheduled Distribution Date.

     At the time of repurchase of any deficient Mortgage Loan, the Purchaser and
the Seller shall arrange for the   reassignment of the repurchased   Mortgage Loan
to the   Seller   and the   delivery   to the   Seller of any   documents   held by the
Custodian relating to the repurchased Mortgage Loan. In the event the Repurchase
Price is deposited in the Custodial   Account,   the Seller shall,   simultaneously
with such deposit,   give written   notice to the Purchaser   that such deposit has
taken place.   Upon such   repurchase the related   Mortgage Loan Schedule shall be
amended to reflect the   withdrawal   of the   repurchased   Mortgage Loan from this
Agreement.

     As to any   Deleted   Mortgage   Loan   for   which   the   Seller   substitutes   a
Qualified   Substitute   Mortgage   Loan or Loans,   the Seller   shall   effect   such
substitution   by   delivering   to the   Purchaser   for such   Qualified   Substitute
Mortgage   Loan or Loans the Mortgage   Note,   the   Mortgage,   the   Assignment   of
Mortgage and such other   documents and agreements as are set forth in Exhibit 13
hereto,   with the Mortgage Note endorsed as required   therein.   The Seller shall
deposit in the Custodial   Account the Monthly Payment less the Servicing Fee due
on such Qualified   Substitute   Mortgage Loan or Loans in the month following the
date of such   substitution.   Monthly   Payments   due with   respect   to   Qualified
Substitute   Mortgage Loans in the month of substitution   will be retained by the
Seller.   For the month of   substitution,   distributions   to the   Purchaser   will
include the Monthly   Payment due on such Deleted   Mortgage   Loan in the month of
substitution,   and the Seller shall thereafter be entitled to retain all amounts
subsequently   received by the Seller in respect of such Deleted   Mortgage   Loan.
The Seller shall give written notice to the Purchaser that such substitution has


                                        34

<PAGE>

taken place and 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.   Upon   such   substitution,   such
Qualified   Substitute   Mortgage   Loan or Loans   shall be subject to the terms of
this Agreement in all respects, and the Seller shall be deemed to have made with
respect to such Qualified   Substitute   Mortgage Loan or Loans, as of the date of
substitution,   the   covenants,   representations   and   warranties   set   forth   in
Subsections 7.01 and 7.02.

     For any   month   in   which   the   Seller   substitutes   one or more   Qualified
Substitute   Mortgage Loans for one or more Deleted   Mortgage   Loans,   the Seller
will determine the amount (if any) by which the aggregate   principal   balance of
all such Qualified   Substitute   Mortgage Loans as of the date of substitution is
less than the aggregate   Stated   Principal   Balance of all such Deleted Mortgage
Loans (after   application   of scheduled   principal   payments due in the month of
substitution).   An amount   equal to the product of the amount of such   shortfall
multiplied by the   Repurchase   Price shall be   distributed   by the Seller in the
month of substitution   pursuant to the Servicing Addendum.   Accordingly,   on the
date of such   substitution,   the Seller will deposit from its own funds into the
Custodial Account an amount equal to such amount.

     It is understood and agreed that the obligations of the Seller set forth in
this Subsection 7.03 to cure,   substitute for or repurchase a defective Mortgage
Loan   constitute   the sole remedies of the Initial   Purchaser and any subsequent
Purchaser respecting a breach of the foregoing representations and warranties.

     Any cause of action   against   the Seller   relating to or arising out of the
breach of any   representations   and warranties made in Subsections   7.01 or 7.02
shall   accrue as to any Mortgage   Loan upon (i)   discovery of such breach by the
Purchaser or notice thereof by the Seller to the Purchaser, and (ii) demand upon
the Seller by the Purchaser for compliance with the relevant   provisions of this
Agreement, which demand shall be made by the Purchaser within ninety days of the
discovery of such breach by the Purchaser.

     In   addition   to   the   foregoing,   in   the   event   that   a   breach   of   any
representation   of the Seller   materially and adversely affects the interests of
the Purchaser in any Prepayment Charge or the   collectability of such Prepayment
Charge,   the Seller shall pay the amount of the scheduled   Prepayment   Charge to
the Purchaser upon the payoff of any related Mortgage Loan.

        Subsection 7.04.   Repurchase of Certain Mortgage Loans; Premium
                           ---------------------------------------------
Protection.
-----------
     (a) In the event that (i) the first Due Date for a   Mortgage   Loan is prior
to the Cut-off Date and the initial   Monthly   Payment is not made by the related
Mortgagor   within   thirty   (30) days of such Due Date or (ii) the first   Monthly
Payment on any Mortgage   Loan due   following the Cut-off Date is not made by the
related Mortgagor within thirty (30) days of the related Due Date, then, in each
such case,   the Seller   shall   repurchase   the   affected   Mortgage   Loans at the
Repurchase   Price within sixty (60)   Business Days   following   receipt of notice
from the   Purchaser   of such   payment   default.   The   Seller   shall   notify   the
Purchaser of any such default under this   Subsection   7.04(a) within thirty (30)
days of any such   Mortgage   Loan   becoming   thirty   (30)   days   delinquent.   The
Seller's   obligation to repurchase such Mortgage Loan shall be conditioned   upon
the   Purchaser   providing   written   notice to the Seller   within 90 days of such
payment default.


                                       35

<PAGE>

     (b) In the event that any Mortgage   Loan   prepays-in-full   within three (3)
months   following the related   CZlosing Date,   Seller shall remit to the Initial
Purchaser within thirty (30) Business Days following   receipt of notice from the
Initial Purchaser of a prepayment-in-full, an amount equal to the product of (i)
the excess of (A) the percentage of par as stated in the related Confirmation as
the purchase price percentage   (subject to adjustment as provided   therein) over
(B) 100%, times (ii) the outstanding   principal balance of such Mortgage Loan as
of the Cut-off Date. Such obligation to the Initial   Purchaser shall survive any
sale or assignment of the Mortgage   Loans by the Initial   Purchaser to any third
party and shall be   independently   enforceable   by the   Initial   Purchaser.   The
Seller's   obligation to remit premium   shall be   conditioned   upon the Purchaser
providing written notice to the Seller within 90 days of such prepayment.

     (c) In the event that any Mortgage Loan is repurchased   pursuant to Section
7.03 or 7.04(a),   in addition to its obligations under Section 7.03 and 7.04(a),
Seller   shall remit to the Initial   Purchaser   an amount equal to the product of
(i)   the   excess   of   (A)   the   percentage   of   par as   stated   in   the   related
Confirmation as the purchase price percentage (subject to adjustment as provided
therein) over (B) 100%,   times (ii) the   outstanding   principal   balance of such
Mortgage   Loan as of the date of   repurchase.   Such   obligation   to the   Initial
Purchaser   shall   survive any sale or   assignment   of the Mortgage   Loans by the
Initial   Purchaser to any third party and shall be independently   enforceable by
the Initial Purchaser.

        Subsection 7.05.    Protection of Consumer Information.
                           ----------------------------------

     Both the   Purchaser   and the Company (i) shall   comply with any   applicable
laws and regulations regarding the privacy and security of Consumer Information,
(ii) shall not use   Consumer   Information   in any manner   inconsistent   with any
applicable laws and   regulations   regarding the privacy and security of Consumer
Information,   (iii) shall not disclose   Consumer   Information   to third   parties
except at the specific   written   direction of the Company,   (iv) shall   maintain
adequate physical,   technical and administrative   safeguards to protect Consumer
Information   from   unauthorized   access,   and (v) shall   immediately   notify the
Company of any actual or   suspected   breach of the   confidentiality   of Consumer
Information.

               or expense;   provided   however,   that the Seller   will   provide a
               certificate   to the Purchaser or any Depositor   showing that such

               Seller (or Third-Party   Originator)   Static Pool Information with
               respect to more than one mortgage loan type, the Purchaser or any
               Depositor   shall be   entitled to specify   whether   some or all of

               for the Purchaser or any Depositor.   Such Static Pool Information
               for each vintage   origination year or prior   securitized pool, as
               applicable,   shall be presented in increments no less   frequently
