         POOLING AND SERVICING AGREEMENT, dated as of August 1, 2003, by and
among CWABS, INC., a Delaware corporation, as depositor (the "Depositor"),
COUNTRYWIDE HOME LOANS, INC., a New York corporation, as seller (the "Seller"),
COUNTRYWIDE HOME LOANS SERVICING LP, a Texas limited partnership, as master
servicer (the "Master Servicer"), THE BANK OF NEW YORK, a New York banking
corporation, as trustee (the "Trustee"), and BNY WESTERN TRUST COMPANY, a
California banking corporation, as Co-Trustee (the "Co-Trustee").

                             PRELIMINARY STATEMENT:

         The Depositor intends to sell mortgage asset-backed pass-through
certificates (collectively, the "Certificates"), to be issued hereunder in
thirteen classes, which in the aggregate will evidence the entire beneficial
ownership interest in the Mortgage Loans (as defined herein).

                                     REMIC I

         As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets (exclusive of the Cap Contracts and the Carryover Reserve Fund)
subject to this Agreement as a real estate mortgage investment conduit (a
"REMIC") for federal income tax purposes, and such segregated pool of assets
will be designated as "REMIC I." The Class R-I Interest will represent the sole
class of "residual interests" in REMIC I for purposes of the REMIC Provisions
(as defined herein) under federal income tax law. The following table
irrevocably sets forth the designation, remittance rate (the "Uncertificated
REMIC I Pass-Through Rate") and initial Uncertificated Principal Balance for
each of the "regular interests" in REMIC I (the "REMIC I Regular Interests").
The "latest possible maturity date" (determined solely for purposes of
satisfying Treasury regulation Section 1.860G-1(a)(4)(iii)) for each REMIC I
Regular Interest shall be the 360th Distribution Date. None of the REMIC I
Regular Interests will be certificated.

         Section 1.01 Defined Terms.

         In addition to those defined terms defined in Section 1.02, whenever

made on the basis of a 360-day year consisting of twelve 30-day months. The

         In addition, in connection with the assignment of any MERS Mortgage
Loan, the Seller agrees that it will cause, at the Seller's own expense, the
MERS(R) System to indicate (and provide evidence to the Trustee that it has done

Seller shall promptly deliver or cause to be delivered to the Co-Trustee such
original Mortgage and such assignment or assignments with evidence of recording
indicated thereon upon receipt thereof from the public recording official, or a
copy thereof, certified, if appropriate, by the relevant recording office, but
in no event shall any such delivery be made later than 270 days following the
Closing Date; provided that in the event that by such date the Seller is unable
to deliver or cause to be delivered each such Mortgage and each interim
assignment by reason of the fact that any such documents have not been returned
by the appropriate recording office, or, in the case of each interim assignment,
because the related Mortgage has not been returned by the appropriate recording
office, the Seller shall deliver or cause to be delivered such documents to the
Co-Trustee as promptly as possible upon receipt thereof. If the public recording
office in which a Mortgage or interim assignment thereof is recorded retains the
original of such Mortgage or assignment, a copy of the original Mortgage or
assignment so retained, with evidence of recording thereon, certified to be true

accordance with the foregoing or (y) lost after recording, the Seller shall
deliver to the Co-Trustee a copy of such document certified by the applicable
public recording office to be a true and complete copy of the original recorded
document. The Seller shall promptly forward or cause to be forwarded to the
Co-Trustee (x) from time to time additional original documents evidencing an
assumption or

to which the related Mortgaged Property and Mortgage File are located in (a) the

to protect the Trustee's and the Certificateholders, interest in the related
Mortgage Loan, as evidenced by an Opinion of Counsel, delivered by the Seller to
the Trustee and a copy to the Rating Agencies, in lieu of recording the
assignment specified in clause (iii) above, the Seller may deliver an unrecorded
assignment in blank, in form otherwise suitable for recording to the Co-Trustee;
provided that if the related Mortgage has not been returned from the applicable
public recording office, such assignment, or any copy thereof, of the Mortgage
may exclude the information to be provided by the recording office. As to any
Mortgage Loan other than a MERS Mortgage Loan, the procedures of the preceding
sentence shall be applicable only so long as the related Mortgage File is
maintained in the possession of the Co-Trustee in the State or jurisdiction
described in such sentence. In the event that with respect to Mortgage Loans
other than MERS Mortgage Loans (i) the Seller, the Depositor or the Master
Servicer gives written notice to the Trustee that recording is required to
protect the right, title and interest of the Trustee on behalf of the
Certificateholders in and to any Mortgage Loan, (ii) a court recharacterizes the
sale of the Mortgage Loans as a financing, or (iii) as a result of any change in
or amendment to the laws of the State or jurisdiction described in the first
sentence of this paragraph or any applicable political subdivision thereof, or
any change in official position regarding application or interpretation of such
laws, including a holding by a court of competent jurisdiction, such recording
is so required, the Trustee or the Co-Trustee shall complete the assignment in
the manner specified in clause (iii) of the second paragraph of this Section
2.01 and the Seller shall submit or cause to be submitted for recording as
specified above or, should the Seller fail to perform such obligations, the
Trustee shall cause the Master Servicer, at the Master Servicer's expense, to
cause each such previously unrecorded assignment to be submitted for recording
as specified above. In the event a Mortgage File is released to the Master
Servicer as a result of the Master Servicer's having completed a Request for

hereunder, file such assignments for recordation in the appropriate real

         In the case of Mortgage Loans that become the subject of a Principal
Prepayment between the Closing Date and the Cut-off Date, the Seller shall
deposit or cause to be deposited in the Certificate Account the amount required
to be deposited therein with respect to such payment pursuant to Section 3.05
hereof.

         Notwithstanding anything to the contrary in this Agreement, within
thirty days after the Closing Date, the Seller shall either (i) deliver to the
Co-Trustee the Mortgage File as required pursuant to this Section 2.01 for each
Delay Delivery Mortgage Loan or (ii) (A) repurchase the Delay Delivery Mortgage
Loan or (B) substitute the Delay Delivery Mortgage Loan for a Replacement
Mortgage Loan, which repurchase or substitution shall be accomplished in the
manner and subject to the conditions set forth in Section 2.03, provided that if
the Seller fails to deliver a Mortgage File for any Delay Delivery Mortgage Loan
within the period provided in the prior sentence, the cure period provided for
in Section 2.02 or in Section 2.03 shall not apply to the initial delivery of
the Mortgage File for such Delay Delivery Mortgage Loan, but rather the Seller
shall have five (5) Business Days to cure such failure to deliver; and provided
further, that the Seller shall use its best efforts to substitute rather than
repurchase. The Seller shall promptly provide each Rating Agency with written
notice of any cure, repurchase or substitution made pursuant to the proviso of
the preceding sentence. On or before the thirtieth (30th) day (or if such
thirtieth day is not a Business Day, the succeeding Business Day) after the
Closing Date (in the case of the Mortgage Loans), the Trustee shall, in
accordance with the provisions of Section 2.02, send a Delay Delivery
Certification substantially in the form annexed hereto as Exhibit G-3 (with any
applicable exceptions noted thereon) for all Delay Delivery Mortgage Loan
delivered within thirty (30) days after such date. The Trustee will promptly
send a copy of such Delay Delivery Certification to each Rating Agency.

                  Section 2.02 Acceptance of the Mortgage Loans.

         (a) The Co-Trustee acknowledges receipt, subject to the limitations
contained in and any exceptions noted in the Initial Certification in the form
annexed hereto as Exhibit G 1 and in the list of exceptions attached thereto, of
the documents referred to in clauses (i) and (iii) of Section 2.01(g) above with
respect to the Mortgage Loans and all other assets included in the Trust Fund
and declares that it holds and will hold such documents and the other documents
delivered to it constituting the Mortgage Files, and that it holds or will hold
such other assets included in the Trust Fund, in trust for the exclusive use and
benefit of all present and future Certificateholders.

         The Trustee agrees to execute and deliver on the Closing Date to the
Depositor, the Master Servicer and the Seller an Initial Certification
substantially in the form annexed hereto as Exhibit G 1 to the effect 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 such
certification as not covered by such certification), the documents described in
Section 2.01(g)(i) and, in the case of each Mortgage Loan that is not a MERS
Mortgage Loan, the documents described in Section 2.01(g)(iii), with respect to
such Mortgage Loan are in the Co-Trustee's possession, and based on its review
and examination and only as to the foregoing documents, such documents appear
regular on their face and relate to such Mortgage Loan. The Trustee agrees to
execute and deliver within 30 days after


                                       58

<PAGE>



the Closing Date to the Depositor, the Master Servicer and the Seller an Interim
Certification substantially in the form annexed hereto as Exhibit G-2 to the
effect 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 such certification as not covered by such certification), all
documents required to be delivered to the Co-Trustee pursuant to this Agreement
with respect to such Mortgage Loan are in its possession (except those described
in Section 2.01(g)(vi)) and based on its review and examination and only as to
the foregoing documents, (i) such documents appear regular on their face and
relate to such Mortgage Loan, and (ii) the information set forth in items (i),
(iv), (v), (vi), (viii), (xi) and (xiv) of the definition of the "Mortgage Loan
Schedule" accurately reflects information set forth in the Mortgage File. On or
before the thirtieth (30th) day after the Closing Date (or if such thirtieth day
is not a Business Day, the succeeding Business Day), the Trustee shall deliver
to the Depositor, the Master Servicer and the Seller a Delay Delivery
Certification with respect to the Mortgage Loans substantially in the form
annexed hereto as Exhibit G-3, with any applicable exceptions noted thereon. The
Co-Trustee or the Trustee, as applicable, shall be under no duty or obligation
to inspect, review or examine such documents, instruments, certificates or other
papers to determine that the same are genuine, enforceable or appropriate for
the represented purpose or that they have actually been recorded in the real
estate records or that they are other than what they purport to be on their
face.

         Not later than 180 days after the Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and the Seller (and to any
Certificateholder that so requests) a Final Certification with respect to the
Mortgage Loans substantially in the form annexed hereto as Exhibit H, with any
applicable exceptions noted thereon.

         In connection with the Trustee's completion and delivery of such Final
Certification, the Co-Trustee, at the Trustee's direction, shall review each
Mortgage File with respect to the Mortgage Loans to determine that such Mortgage
File contains the documents listed in Section 2.01(g). If, in the course of such
review, the Co-Trustee finds any document or documents constituting a part of
such Mortgage File that do not meet the requirements of clauses (i)-(iv) and
(vi) of Section 2.01(g), the Trustee shall include such exceptions in such Final
Certification (and the Trustee shall state in such Final Certification whether
any Mortgage File does not then include the original or duplicate original
lender's title policy or a printout of the electronic equivalent and all riders
thereto). If the public recording office in which a Mortgage or assignment
thereof is recorded retains the original of such Mortgage or assignment, a copy
of the original Mortgage or assignment so retained, with evidence of recording
thereon, certified to be true and complete by such recording office, shall be
deemed to satisfy the requirements of clause (ii), (iii) or (iv) of Section
2.01(g), as applicable. The Seller shall promptly correct or cure such defect
referred to above within 90 days from the date it was so notified of such defect
and, if the Seller does not correct or cure such defect within such period, the
Seller shall either (A) if the time to cure such defect expires prior to the end
of the second anniversary of the Closing Date, substitute for the related
Mortgage Loan a Replacement Mortgage Loan, which substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03, or (B) purchase such Mortgage Loan from the Trust Fund within 90 days from
the date the Seller was notified of such defect in writing at the Purchase Price
of such Mortgage Loan;


                                       59

<PAGE>



provided that any such substitution pursuant to (A) above or repurchase pursuant
to (B) above shall not be effected prior to the delivery to the Trustee of the
Opinion of Counsel required by Section 2.05 hereof and any substitution pursuant
to (A) above shall not be effected prior to the additional delivery to the
Co-Trustee of a Request for Release substantially in the form of Exhibit N. No
substitution will be made in any calendar month after the Determination Date for
such month. The Purchase Price for any such Mortgage Loan shall be deposited by
the Seller in the Certificate Account and, upon receipt of such deposit and
certification with respect thereto in the form of Exhibit N hereto, the
Co-Trustee shall release the related Mortgage File to the Seller and shall
execute and deliver at the Seller's request such instruments of transfer or
assignment as the Seller has prepared, in each case without recourse, as shall
be necessary to vest in the Seller, or a designee, the Trust Fund's interest in
any Mortgage Loan released pursuant hereto. If pursuant to the foregoing
provisions the Seller repurchases an Mortgage Loan that is a MERS Mortgage Loan,
the Master Servicer shall cause MERS to execute and deliver an assignment of the
Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and
shall cause such Mortgage to be removed from registration on the MERS(R) System
in accordance with MERS' rules and regulations.

         The Co-Trustee shall retain possession and custody of each Mortgage
File in accordance with and subject to the terms and conditions set forth
herein. The Seller shall promptly deliver to the Co-Trustee, upon the execution
or receipt thereof, the originals of such other documents or instruments
constituting the Mortgage File that come into the possession of the Seller from
time to time.

         It is understood and agreed that the obligation of the Seller to
substitute for or to purchase any Mortgage Loan that does not meet the
requirements of Section 2.02(a)(A) or (B) above shall constitute the sole remedy
respecting such defect available to the Trustee, the Co-Trustee, the Depositor
and any Certificateholder against the Seller.

         do business in the jurisdiction where the Mortgaged Property is located
         and acceptable to Fannie Mae or Freddie Mac and is in a form acceptable
         to Fannie Mae or

         Prepayment in full between the Closing Date and the Cut-off Date.

                  (xx) To the best of the Seller's knowledge, all of the
         improvements that were included for the purpose of determining the
         Appraised Value of the Mortgaged Property lie wholly within the
         boundaries and building restriction lines of such property, and no
         improvements on adjoining properties encroach upon the Mortgaged
         Property.

                  (xxi) To the best of the Seller's knowledge, no improvement
         located on or being part of the Mortgaged Property is in violation of
         any applicable zoning law or regulation. To the best of the Seller's
         knowledge, all inspections, licenses and certificates required to be
         made or issued with respect to all occupied portions of the Mortgaged
         Property and, with respect to the use and occupancy of the same,
         including but not limited to certificates of occupancy and fire
         underwriting certificates, have been made or obtained from the
         appropriate authorities, unless the lack thereof would not have a
         material adverse effect on the value of such Mortgaged Property, and
         the Mortgaged Property is lawfully occupied under applicable law.

                  (xxii) 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 and under applicable
         law, except that (a) the enforceability thereof may be limited by
         bankruptcy, insolvency, moratorium, receivership and other similar laws
         relating to creditors' rights generally and (b) the remedy of specific
         performance and injunctive and other forms of equitable relief may be
         subject to equitable defenses and to the discretion of the court before
         which any proceeding therefor may be brought. To the best of the
         Seller's knowledge, all parties to the Mortgage Note and the Mortgage
         had legal capacity to execute the Mortgage Note and the Mortgage and
         each Mortgage Note and Mortgage have been duly and properly executed by
         such parties.

                  (xxiii) The proceeds of the Mortgage Loan have been fully
         disbursed, there is no requirement for future advances thereunder, and
         any and all requirements as to completion of any on-site or off-site
         improvements and as to disbursements of any escrow funds therefor have
         been complied with. All costs, fees and expenses incurred in making, or
         closing or recording the Mortgage Loans were paid.

                  (xxiv) The related Mortgage contains customary and enforceable
         provisions that render the rights and remedies of the holder thereof
         adequate for the realization against the Mortgaged Property of the
         benefits of the security, including, (i) in the case of a Mortgage
         designated as a deed of trust, by trustee's sale, and (ii) otherwise by
         judicial foreclosure.

                  (xxv) With respect to each Mortgage constituting 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
         such Mortgage, and no fees or expenses are or will become payable by
         the Certificateholders to the trustee under the deed of trust, except
         in connection with a trustee's sale after default by the Mortgagor.

                  (xxvi) Each Mortgage Note and each Mortgage is in
         substantially one of the forms attached hereto as Exhibit P acceptable
         in form to Fannie Mae or Freddie Mac.

                  (xxvii) There exist no deficiencies with respect to escrow
         deposits and payments, if such are required, for which customary
         arrangements for repayment thereof have not been made, and no escrow
         deposits or payments of other charges or payments due the Seller have
         been capitalized under the Mortgage or the related Mortgage Note.

                  (xxviii) The origination, underwriting, servicing and
         collection practices used by the Seller with respect to each Mortgage
         Loan have been in all respects legal, proper, prudent and customary in
         the mortgage lending and servicing business.

                  (xxix) There is no pledged account or other security other
         than real estate securing the Mortgagor's obligations.

                  (xxx) No Mortgage Loan has a shared appreciation feature, or
         other contingent interest feature.

                  (xxxi) Each Mortgage Loan contains a customary "due on sale"
         clause.

                  (xxxii) No more than approximately 3.63% and 3.83% and of the
         Mortgage Loans in Loan Group 1 and Loan Group 2, respectively, are
         secured by two- to four-family dwellings. No more than approximately
         4.97% and 4.64% of the Mortgage Loans in Loan Group 1 and Loan Group 2,
         respectively, are secured by condominium units. No more than

         a principal balance in excess of $639,112 and $577,399, respectively,
         at origination.

                  (xxxiv) To the extent required under applicable law, each
         originator and subsequent mortgagee or servicer of the Mortgage Loan
         complied with all licensing requirements and was authorized to transact
         and do business in the jurisdiction in which the related Mortgaged
         Property is located at all times when it held or serviced the Mortgage
         Loan. Any and all requirements of any federal, state or local laws or
         regulations, including, without limitation, usury, truth-in-lending,
         real estate settlement procedures, consumer credit protection,
         anti-predatory lending, fair credit reporting, unfair collection

         Mortgage Note, Mortgage and other loan documents have been complied
         with in all material respects; servicing of each Mortgage Loan has been
         in accordance with prudent mortgage servicing standards, any applicable
         laws, rules and regulations and in accordance with the terms of the
         Mortgage Notes, Mortgage and other loan documents, whether such
         origination and servicing was done by Seller, its affiliates, or any
         third party which originated the Mortgage Loan on behalf of, or sold
         the Mortgage Loan to, any of them, or any servicing agent of any of the
         foregoing;

                  (xxxv) Each Mortgage Loan was originated on or after December
         26, 2001;

                  (xxxvi) Each Two-Year Hybrid Mortgage Loan had an initial
         Adjustment Date no later than July 1, 2005; each Three-Year Hybrid
         Mortgage Loan had an initial Adjustment Date no later than June 1,
         2006; each Five-Year Hybrid Mortgage Loan had an initial Adjustment
         Date no later than May 1, 2008.

                  (xxxvii) Approximately 80.41% and 82.15% of the Mortgage Loans
         in Loan Group 1 and Loan Group 2, respectively, provide for a
         prepayment penalty.

                  (xxxviii) On the basis of representations made by the
         Mortgagors in their loan applications, no less than approximately
         99.94% and 99.71% of the owner-occupied Mortgage Loans in Loan Group 1
         and Loan Group 2, respectively, are secured by owner-occupied Mortgaged
         Properties that are primary residences and no more than approximately
         0.06% and 0.29% of the owner-occupied Mortgage Loans in Loan Group 1
         and Loan Group 2, respectively, are secured by owner-occupied Mortgaged
         Properties that are secondary residences.

                  (xxxix) At the Cut-off Date, the improvements upon each
         Mortgaged Property are covered by a valid and existing hazard insurance
         policy with a generally acceptable carrier that provides for fire and
         extended coverage and coverage for such other hazards as are customary
         in the area where the Mortgaged Property is located in an amount that
         is at least equal to the lesser of (i) the maximum insurable value of
         the improvements securing


                                       67

<PAGE>



         such Mortgage Loan or (ii) the greater of (a) the outstanding principal
         balance of the Mortgage Loan and (b) an amount such that the proceeds
         of such policy shall be sufficient to prevent the Mortgagor and/or the
         mortgagee from becoming a co-insurer. If the Mortgaged Property is a
         condominium unit, it is included under the coverage afforded by a
         blanket policy for the condominium unit. All such individual insurance
         policies and all flood policies referred to in item (xl) below contain
         a standard mortgagee clause naming the Seller or the original
         mortgagee, and its successors in interest, as mortgagee, and the Seller
         has received no notice that any premiums due and payable thereon have
         not been paid; the Mortgage obligates the Mortgagor thereunder to
         maintain all such insurance, including flood insurance, at the
         Mortgagor's cost and expense, and upon the Mortgagor's failure to do
         so, authorizes the holder of the Mortgage to obtain and maintain such
         insurance at the Mortgagor's cost and expense and to seek reimbursement
         therefor from the Mortgagor.

                  (xl) If the Mortgaged Property is in an area identified in the
         Federal Register by the Federal Emergency Management Agency as having
         special flood hazards, a flood insurance policy in a form meeting the
         requirements of the current guidelines of the Flood Insurance
         Administration is in effect with respect to such Mortgaged Property
         with a generally acceptable carrier in an amount representing coverage
         not less than the least of (A) the original outstanding principal
         balance of the Mortgage Loan, (B) the minimum amount required to
         compensate for damage or loss on a replacement cost basis, or (C) the
         maximum amount of insurance that is available under the Flood Disaster
         Protection Act of 1973, as amended.

                  (xli) To the best of the Seller's knowledge, there is no
         proceeding occurring, pending or threatened for the total or partial
         condemnation of the Mortgaged Property.

                  (xlii) There is no material monetary default existing under
         any Mortgage or the related Mortgage Note and, to the best of the
         Seller's knowledge, there is no material event that, 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
         under the Mortgage or the related Mortgage Note; and the Seller has not
         waived any default, breach, violation or event of acceleration.

                  (xliii) Each Mortgaged Property is improved by a one- to
         four-family residential dwelling, including condominium units and
         dwelling units in PUDs. To the best of the Seller's knowledge, no
         Mortgaged Property includes a cooperative or a mobile home or
         constitutes other than real property under state law.

                  (xliv) Each Mortgage Loan is being serviced by the Master
         Servicer, or, if a Mortgage Loan is being serviced by the originator of
         such Mortgage Loan, the Master Servicer and the originator have agreed
         to transfer the servicing of such Mortgage Loan on or prior to October
         28, 2003.

<PAGE>



                  (xlv) Any future advances made prior to the Cut-off Date have
         been consolidated with the outstanding principal amount secured by the
         Mortgage, and the secured principal amount, as consolidated, bears a
         single interest rate and single repayment term reflected on the
         Mortgage Loan Schedule. The consolidated principal amount does not
         exceed the original principal amount of the Mortgage Loan. The Mortgage
         Note does not permit or obligate the Master Servicer to make future
         advances to the Mortgagor at the option of the Mortgagor.

                  (xlvi) All taxes, governmental assessments, insurance
         premiums, water, sewer and municipal charges, leasehold payments or
         ground rents that previously became due and owing have been paid, or an
         escrow of funds has been established in an amount sufficient to pay for
         every such item that remains unpaid and that has been assessed, but is
         not yet due and payable. Except for (A) payments in the nature of
         escrow payments, and (B) interest accruing from the date of the
         Mortgage Note or date of disbursement of the Mortgage proceeds,
         whichever is later, to the day that precedes by one month the Due Date
         of the first installment of principal and interest, including without
         limitation, taxes and insurance payments, the Master Servicer has not
         advanced funds, or induced, solicited or knowingly received any advance
         of funds by a party other than the Mortgagor, directly or indirectly,
         for the payment of any amount required by the Mortgage.

                  (xlvii) The Mortgage Loans were underwritten in all material
         respects in accordance with customary and prudent underwriting
         guidelines generally used by originators of credit blemished quality
         mortgage loans.

                  (xlviii) Prior to the approval of the Mortgage Loan
         application, an appraisal of the related Mortgaged Property was
         obtained from a qualified appraiser, duly appointed by the originator,
         who had no interest, direct or indirect, in the Mortgaged Property or
         in any loan made on the security thereof, and whose compensation is not
         affected by the approval or disapproval of the Mortgage Loan; such
         appraisal is in a form acceptable to Fannie Mae and Freddie Mac.

                  (xlix) None of the Mortgage Loans is a graduated payment
         mortgage loan or a growing equity mortgage loan, and no Mortgage Loan
         is subject to a buydown or similar arrangement.

                  (l) The Mortgage Rates borne by the Mortgage Loans in Loan
         Group 1 as of the Cut-off Date ranged from 5.12% per annum to 12.500%
         per annum and the weighted average Mortgage Rate as of the Cut-off Date
         was 7.49% per annum. The Mortgage Rates borne by the Mortgage Loans in
         Loan Group 2 as of the Cut-off Date ranged from 4.70% per annum to
         12.78% per annum and the weighted average Mortgage Rate as of the
         Cut-off Date was 7.46% per annum.

<PAGE>



                  (li) The Mortgage Loans were selected from among the
         outstanding one- to four-family mortgage loans in the Seller's
         portfolio at the Closing Date, as to which the representations and
         warranties made as to the Mortgage Loans set forth in this Section
         2.03(b) can be made. No selection was made in a manner that would
         adversely affect the interests of Certificateholders.

                  (lii) The Gross Margins on the Adjustable Rate Mortgage Loans
         that are Mortgage Loans in Loan Group 1 range from approximately 3.95%
         to 11.49% and the weighted average Gross Margin was approximately
         6.60%. The Gross Margins on the Adjustable Rate Mortgage Loans that are
         Mortgage Loans in Loan Group 2 range from approximately 2.00% to 10.81%
         and the weighted average Gross Margin was approximately 6.65%.

                  (liii) Each Mortgage Loan has a payment date on or before the
         Due Date in the month of the first Distribution Date.

                  (liv) The Mortgage Loans, individually and in the aggregate,
         conform in all material respects to the descriptions thereof in the
         Prospectus Supplement.

                  (lv) There is no obligation on the part of the Seller under
         the terms of the Mortgage or related Mortgage Note to make payments in
         addition to those made by the Mortgagor.

                  (lvi) Any leasehold estate securing a Mortgage Loan has a term
         of not less than five years in excess of the term of the related
         Mortgage Loan.

                  (lvii) Each Mortgage Loan represents a "qualified mortgage"
         within the meaning of Section 860(a)(3) of the Code (but without regard
         to the rule in Treasury Regulation ss. 1.860G 2(f)(2) that treats a
         defective obligation as a qualified mortgage, or any substantially
         similar successor provision) and applicable Treasury regulations
         promulgated thereunder.

                  (lviii) No Mortgage Loan was either a "consumer credit
         contract" or a "purchase money loan" as such terms are defined in 16
         C.F.R. Section 433 nor is any Mortgage Loan a "mortgage" as defined in
         15 U.S.C. ss. 1602(aa).

                  (lix) The information set forth in the Prepayment Charge
         Schedule with respect to each Mortgage Loan is complete, true and
         correct in all material respects at the date or dates respecting which
         such information is furnished and each Prepayment Charge is permissible
         and enforceable in accordance with its terms under applicable law upon
         the Mortgagor's full and voluntary principal prepayment (except to the
         extent that: (1) the enforceability thereof may be limited by
         bankruptcy, insolvency, moratorium, receivership and other similar laws
         relating to creditors' rights generally; or (2) the collectibility
         thereof may be limited due to acceleration in connection with a
         foreclosure or other involuntary prepayment).

                  (lx) No Mortgage Loan is a "high cost home loan" as defined in
         the Georgia Fair Lending Act, as amended. No Mortgage Loan with a
         principal balance at origination (or modification) equal to or less
         than the mortgage loan balance limit of Fannie Mae in effect at the
         time of origination (or modification) and secured by owner-occupied
         real property located in the State of Georgia was originated (or
         modified) on or after October 1, 2002 through and including March 6,
         2003.

                  (lxi) No Mortgage Loan is a "high cost home loan" as defined
         in New York Banking Law 6-1.

         (c) Upon discovery by any of the parties hereto of a breach of a
representation or warranty set forth in Section 2.03(a) or (b), that materially
and adversely affects the interests of the Certificateholders in any Mortgage
Loan, the party discovering such breach shall give prompt notice thereof to the
other parties. Each of the Master Servicer and the Seller (each, a "Representing
Party") hereby covenants with respect to a breach of the representations and
warranties set forth in Sections 2.03(a) and (b), that within 90 days of the
earlier of the discovery by such Representing Party or receipt of written notice
by such Representing Party from any party of a breach of any representation or
warranty set forth herein made that materially and adversely affects the
interests of the Certificateholders in any Mortgage Loan, it shall cure such
breach in all material respects and, if such breach is not so cured, shall, (i)
if such 90 day period expires prior to the second anniversary of the Closing
Date, remove such Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund
and substitute in its place a Replacement Mortgage Loan, in the manner and
subject to the conditions set forth in this Section; or (ii) repurchase the
affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price
in the manner set forth below; provided that any such substitution pursuant to
(i) above or repurchase pursuant to (ii) above shall not be effected prior to
the delivery to the Trustee of the Opinion of Counsel required by Section 2.05
hereof and any such substitution pursuant to (i) above shall not be effected
prior to the additional delivery to the Trustee of a Request for Release
substantially in the form of Exhibit M. Any Representing Party liable for a
breach under this Section 2.03 shall promptly reimburse the Master Servicer and
the Trustee for any expenses reasonably incurred by the Master Servicer or the
Trustee in respect of enforcing the remedies for such breach. To enable the
Master Servicer to amend the Mortgage Loan Schedule, any Representing Party
liable for a breach under this Section 2.03 shall, unless it cures such breach
in a timely fashion pursuant to this Section 2.03, promptly notify the Master
Servicer whether such Representing Party intends either to repurchase, or to
substitute for, the Mortgage Loan affected by such breach. With respect to the
representations and warranties described in this Section that are made to the
best of the Representing Party's knowledge, if it is discovered by any of the
Depositor, the Master Servicer, the Seller 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, notwithstanding
the Representing Party's lack of knowledge with respect to the substance of such
representation or warranty, such inaccuracy shall be deemed a breach of the
applicable representation or warranty.

         With respect to any Replacement Mortgage Loan or Loans, the Seller
delivering such Replacement Mortgage Loan shall deliver to the Trustee for the
benefit of the Certificateholders the related Mortgage Note, Mortgage and
assignment of the Mortgage, and such other documents and agreements as are
required by Section 2.01, with the Mortgage Note endorsed and the Mortgage
assigned as required by Section 2.01. No substitution will be made in any
calendar month after the Determination Date for such month. Scheduled Payments
due with respect to Replacement Mortgage Loans in the Due Period related to the
Distribution Date on which such proceeds are to be distributed shall not be part
of the Trust Fund and will be retained by the Seller delivering such Replacement
Loan on such Distribution Date. For the month of substitution, distributions to
Certificateholders will include the Scheduled Payment due on any Deleted
Mortgage Loan for the related Due Period and thereafter the Seller shall be
entitled to retain all amounts received in respect of such Deleted Mortgage
Loan. The Master Servicer shall amend the Mortgage Loan Schedule for the benefit
of the Certificateholders to reflect the removal of such Deleted Mortgage Loan
and the substitution of the Replacement Mortgage Loan or Loans and the Master
Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee. Upon
such substitution, the Replacement Mortgage Loan or Loans shall be subject to
the terms of this Agreement in all respects, and the Seller delivering such
Replacement Mortgage Loan shall be deemed to have made with respect to such
Replacement Mortgage Loan or Loans, as of the date of substitution, the
representations and warranties set forth in Section 2.03(b) with respect to such
Mortgage Loan. Upon any such substitution and the deposit to the Certificate
Account of the amount required to be deposited therein in connection with such
substitution as described in the following paragraph, the Co-Trustee shall
release to the Representing Party the Mortgage File relating to such Deleted
Mortgage Loan and held for the benefit of the Certificateholders and shall
execute and deliver at the Master Servicer's direction such instruments of
transfer or assignment as have been prepared by the Master Servicer, in each
case without recourse, as shall be necessary to vest in the Seller, or its
respective designee, title to the Trustee's interest in any Deleted Mortgage
Loan substituted for pursuant to this Section 2.03.

         For any month in which the Seller substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer will
determine the amount (if any) by which the aggregate principal balance of all
such Replacement Mortgage Loans as of the date of substitution is less than the
Stated Principal Balance (after application of the principal portion of the
Scheduled Payment due (in the case of Actuarial Mortgage Loans) in the month of
substitution) of all such Deleted Mortgage Loans. An amount equal to the
aggregate of the deficiencies described in the preceding sentence (such amount,
the "Substitution Adjustment Amount") shall be forwarded by the Seller to the
Master Servicer and deposited by the Master Servicer into the Certificate
Account not later than the Determination Date for the Distribution Date relating
to the Prepayment Period during which the related Mortgage Loan became required
to be purchased or replaced hereunder.

         In the event that a Seller shall have repurchased a Mortgage Loan, the
Purchase Price therefor shall be deposited in the Certificate Account pursuant
to Section 3.08 on the Determination Date for the Distribution Date in the month
following the month during which such Seller became obligated


                                       72

<PAGE>



to repurchase or replace such Mortgage Loan and upon such deposit of the
Purchase Price, the delivery of the Opinion of Counsel required by Section 2.05,
if any, and the receipt of a Request for Release in the form of Exhibit N
hereto, the Co-Trustee shall release the related Mortgage File held for the
benefit of the Certificateholders to such Seller, and the Trustee shall execute
and deliver at such Person's direction the related instruments of transfer or
assignment prepared by such Seller, in each case without recourse, as shall be
necessary to transfer title from the Trustee for the benefit of the
Certificateholders and transfer the Trustee's interest to such Seller to any
Mortgage Loan purchased pursuant to this Section 2.03. It is understood and
agreed that the obligation under this Agreement of the Seller to cure,
repurchase or replace any Mortgage Loan as to which a breach has occurred and is
continuing shall constitute the sole remedy against the Seller respecting such
breach available to Certificateholders, the Depositor or the Trustee.

         (d) The representations and warranties set forth in Section 2.03 hereof
shall survive delivery of the respective Mortgage Files to the Co-Trustee for
the benefit of the Certificateholders.

         Section 2.04 Representations and Warranties of the Depositor.

         The Depositor hereby represents and warrants to the Seller, the Master
Servicer and the Trustee as follows, as of the date hereof:

                  (i) The Depositor is duly organized and is validly existing as
         a corporation in good standing under the laws of the State of Delaware
         and has full power and authority (corporate and other) necessary to own
         or hold its properties and to conduct its business as now conducted by
         it and to enter into and perform its obligations under this Agreement.

                  (ii) The Depositor has the full corporate power and authority
         to execute, deliver and perform, and to enter into and consummate the
         transactions contemplated by, this Agreement and has duly authorized,
         by all necessary corporate action on its part, the execution, delivery
         and performance of this Agreement; and this Agreement, assuming the due
         authorization, execution and delivery hereof by the other parties
         hereto, constitutes a legal, valid and binding obligation of the
         Depositor, enforceable against the Depositor in accordance with its
         terms, subject, as to enforceability, to (i) bankruptcy, insolvency,
         reorganization, moratorium and other similar laws affecting creditors'
         rights generally and (ii) general principles of equity, regardless of
         whether enforcement is sought in a proceeding in equity or at law.

                  (iii) The execution and delivery of this Agreement by the
         Depositor, the consummation of the transactions contemplated by this
         Agreement, and the fulfillment of or compliance with the terms hereof
         and thereof are in the ordinary course of business of the Depositor and
         will not (A) result in a material breach of any term or provision of
         the charter or by-laws of the Depositor or (B) materially conflict
         with, result in a material breach, violation or acceleration of, or
         result in a material default under, the terms of any other material
         agreement or instrument to which the Depositor is a party or by which
         it may be


                                       73

<PAGE>



         bound or (C) constitute a material violation of any statute, order or
         regulation applicable to the Depositor of any court, regulatory body,
         administrative agency or governmental body having jurisdiction over the
         Depositor; and the Depositor is not in breach or violation of any
         material indenture or other material agreement or instrument, or in
         violation of any statute, order or regulation of any court, regulatory
         body, administrative agency or governmental body having jurisdiction
         over it which breach or violation may materially impair the Depositor's
         ability to perform or meet any of its obligations under this Agreement.

                  (iv) No litigation is pending, or, to the best of the
         Depositor's knowledge, threatened, against the Depositor that would
         materially and adversely affect the execution, delivery or
         enforceability of this Agreement or the ability of the Depositor to
         perform its obligations under this Agreement in accordance with the
         terms hereof and thereof.

                  (v) No consent, approval, authorization or order of any court
         or governmental agency or body is required for the execution, delivery
         and performance by the Depositor of, or compliance by the Depositor
         with, this Agreement or the consummation of the transactions
         contemplated hereby, or if any such consent, approval, authorization or
         order is required, the Depositor has obtained the same.

         The Depositor hereby represents and warrants to the Trustee with
respect to each Mortgage Loan as of the Closing Date, that following the
transfer of the Mortgage Loans to it by the Seller, the Depositor had good title
to the Mortgage Loans, and the related Mortgage Notes were subject to no
offsets, claims, defenses or counterclaims.

         It is understood and agreed that the representations and warranties set
forth in the two immediately preceding paragraphs shall survive delivery of the
Mortgage Files to the Co-Trustee. Upon discovery by the Depositor or the Trustee
of a breach of any of the foregoing representations and warranties set forth in
the immediately preceding paragraph (referred to herein as a "breach"), which
breach materially and adversely affects the interest of the Certificateholders,
the party discovering such breach shall give prompt written notice to the others
and to each Rating Agency. The Depositor hereby covenants with respect to the
representations and warranties made by it in this Section 2.04 that within 90
days of the earlier of the discovery it or receipt of written notice by it from
any party of a breach of any representation or warranty set forth herein made
that materially and adversely affects the interests of the Certificateholders in
any Mortgage Loan, it shall cure such breach in all material respects and, if
such breach is not so cured, shall repurchase or replace the affected Mortgage
Loan or Loans in accordance with the procedure set forth in Section 2.03(c).

         Section 2.05 Delivery of Opinion of Counsel in Connection with
                      Substitutions and Repurchases.

         (a) Notwithstanding any contrary provision of this Agreement, with
respect to any Mortgage Loan that is not in default or as to which default is
not imminent, no repurchase or substitution pursuant to Sections 2.02, 2.03 or
2.04 shall be made unless the Representing Party


                                       74

<PAGE>



making such repurchase or substitution delivers to the Trustee an Opinion of
Counsel, addressed to the Trustee, to the effect that such repurchase or
substitution would not (i) result in the imposition of the tax on "prohibited
transactions" of the Trust Fund or contributions after the Closing Date, as
defined in sections 860F(a)(2) and 860G(d) of the Code, respectively or (ii)
cause the Trust Fund to fail to qualify as a REMIC at any time that any
Certificates are outstanding. Any Mortgage Loan as to which repurchase or
substitution was delayed pursuant to this paragraph shall be repurchased or the
substitution therefor shall occur (subject to compliance with Sections 2.02,
2.03 or 2.04) upon the earlier of (a) the occurrence of a default or imminent
default with respect to such loan and (b) receipt by the Trustee of an Opinion
of Counsel to the effect that such repurchase or substitution, as applicable,
will not result in the events described in clause (i) or clause (ii) of the
preceding sentence.

         (b) Upon discovery by the Depositor, the Seller, the Master Servicer 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 promptly (and in any event within 5 Business Days of discovery) give
written notice thereof to the other parties. In connection therewith, the
Trustee shall require the Seller, at the Seller's option, to either (i)
substitute, if the conditions in Section 2.03(b) with respect to substitutions
are satisfied, a Replacement Mortgage Loan for the affected Mortgage Loan, or
(ii) repurchase the affected Mortgage Loan within 90 days of such discovery in
the same manner as it would a Mortgage Loan for a breach of representation or
warranty contained in Section 2.03. 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 contained in Section 2.03.

         Section 2.06      Authentication and Delivery of Certificates.

         The Trustee acknowledges the transfer and assignment to it of the Trust
Fund and, concurrently with such transfer and assignment, has executed,
authenticated and delivered, to or upon the order of the Depositor, the
Certificates in authorized denominations evidencing the entire ownership of the
Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the rights
referred to above for the benefit of all present and future Holders of the
Certificates and to perform the duties set forth in this Agreement to the best
of its ability, to the end that the interests of the Holders of the Certificates
may be adequately and effectively protected.

         Section 2.07      Covenants of the Master Servicer.

         The Master Servicer hereby covenants to the Depositor, the Seller and
the Trustee as follows:

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

         (b) no written information, certificate of an officer, statement
furnished in writing or written report delivered to the Depositor, any affiliate
of the Depositor or the Trustee and prepared


                                       75

<PAGE>



by the Master Servicer pursuant to this Agreement will contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the information, certificate, statement or report not misleading.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

         Section 3.01      Master Servicer to Service Mortgage Loans.

         For and on behalf of the Certificateholders, the Master Servicer shall
service and administer the Mortgage Loans in accordance with customary and usual
standards of practice of prudent mortgage loan lenders in the respective states
in which the Mortgaged Properties are located. In connection with such servicing
and administration, the Master Servicer shall have full power and authority,
acting alone and/or through subservicers as provided in Section 3.02 hereof,
subject to the terms hereof (i) to execute and deliver, on behalf of the
Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages (but only
in the manner provided in this Agreement), (iii) to collect any Insurance
Proceeds and other Liquidation Proceeds, and (iv) subject to Section 3.12(a), to
effectuate foreclosure or other conversion of the ownership of the Mortgaged
Property securing any Mortgage Loan; provided that the Master Servicer shall
take no action that is inconsistent with or prejudices the interests of the
Trust Fund or the Certificateholders in any Mortgage Loan or the rights and
interests of the Depositor and the Trustee under this Agreement. The Master
Servicer shall represent and protect the interest of the Trust Fund in the same
manner as it currently protects its own interest in mortgage loans in its own
portfolio in any claim, proceeding or litigation regarding a Mortgage Loan and
shall not make or permit any modification, waiver or amendment of any term of
any Mortgage Loan which would cause the Trust Fund to fail to qualify as a REMIC
or result in the imposition of any tax under Section 860(a) or 860(d) of the
Code, but in any case not in any manner that is a lesser standard than that
provided in the first sentence of this Section 3.01. Without limiting the
generality of the foregoing, the Master Servicer, in its own name or in the name
of the Depositor and the Trustee, is hereby authorized and empowered by the
Depositor and the Trustee, when the Master Servicer believes it appropriate in
its reasonable judgment, to execute and deliver, on behalf of the Trustee, the
Depositor, the Certificateholders or any of them, any and all instruments of
satisfaction or cancellation, or of partial or full release or discharge and all
other comparable instruments, with respect to the Mortgage Loans, and with
respect to the Mortgaged Properties held for the benefit of the
Certificateholders. The Master Servicer shall prepare and deliver to the
Depositor and/or the Trustee such documents requiring execution and delivery by
any or all of them as are necessary or appropriate to enable the Master Servicer
to service and administer the Mortgage Loans. Upon receipt of such documents,
the Depositor and/or the Trustee shall execute such documents and deliver them
to the Master Servicer. The Master Servicer further is authorized and empowered
by the Trustee, on behalf of the Certificateholders and the Trustee, in its own
name or in the name of the Subservicer, when the Master Servicer or the
Subservicer, as the case may be, believes it appropriate in its best judgment to
register any Mortgage Loan on the MERS(R) System, or cause the removal from the
registration of any Mortgage Loan on the MERS(R) System, to execute and deliver,
on behalf of the Trustee and the Certificateholders or any of them, any and all
instruments of


                                       77

<PAGE>



assignment and other comparable instruments with respect to such assignment or
re-recording of a Mortgage in the name of MERS, solely as nominee for the
Trustee and its successors and assigns.

         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 payment of taxes and assessments on the Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.06, and further as
provided in Section 3.08. All costs incurred by the Master Servicer, if any, in
effecting the timely payments of taxes and assessments on the Mortgaged
Properties and related insurance premiums shall not, for the purpose of
calculating monthly distributions to the Certificateholders, be added to the
Stated Principal Balance under the related Mortgage Loans, notwithstanding that
the terms of such Mortgage Loans so permit.

         The Master Servicer shall deliver a list of Servicing Officers to the
Trustee by the Closing Date.

         In addition, the Master Servicer shall administer the Mortgage
Insurance Policy on behalf of itself, the Seller, the Depositor, and the Trustee
for the benefit of the Certificateholders, when it is necessary to make claims
and receive payments under the Mortgage Insurance Policy. In connection with its
activities as Master Servicer of the Mortgage Loans, the Master Servicer agrees
to present, on behalf of itself, the Trustee and the Certificateholders, claims
to the insurer under any primary insurance policies and, in this regard, to take
any reasonable action necessary to permit recovery under any primary insurance
policies respecting defaulted Mortgage Loans. Any amounts collected by the
Master Servicer under any primary insurance policies shall be deposited in the
Certificate Account.

         Section 3.02 Subservicing; Enforcement of the Obligations of Master
                      Servicer.

         (a) The Master Servicer may arrange for the subservicing of any
Mortgage Loan by a subservicer (each, a "Subservicer") pursuant to a
subservicing agreement (each, a "Subservicing Agreement"); provided that such
subservicing arrangement and the terms of the related subservicing agreement
must provide for the servicing of such Mortgage Loans in a manner consistent
with the servicing arrangements contemplated hereunder. Notwithstanding the
provisions of any subservicing agreement, any of the provisions of this
Agreement relating to agreements or arrangements between the Master Servicer or
a subservicer or reference to actions taken through a Master Servicer or
otherwise, the Master Servicer shall remain obligated and liable to the
Depositor, the Trustee and the Certificateholders for the servicing and
administration of the Mortgage Loans in accordance with the provisions of this
Agreement without diminution of such obligation or liability by virtue of such
subservicing agreements or arrangements or by virtue of indemnification from the
subservicer 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.
Every subservicing agreement entered into by the Master Servicer shall contain a
provision giving the successor Master Servicer the option to terminate such
agreement in the event a successor Master Servicer is appointed. All actions of
each


                                       78

<PAGE>



subservicer performed pursuant to the related subservicing agreement shall be
performed as an agent of the Master Servicer with the same force and effect as
if performed directly by the Master Servicer.

         (b) For purposes of this Agreement, the Master Servicer shall be deemed
to have received any collections, recoveries or payments with respect to the
Mortgage Loans that are received by a subservicer regardless of whether such
payments are remitted by the subservicer to the Master Servicer.

         Section 3.03 Rights of the Depositor, the Seller and the Trustee in
                      Respect of the Master Servicer.

         None of the Trustee, the Seller or the Depositor shall have any
responsibility or liability for any action or failure to act by the Master
Servicer, and none of them is obligated to supervise the performance of the
Master Servicer hereunder or otherwise.

         Section 3.04 Trustee to Act as Master Servicer.

         In the event that the Master Servicer shall for any reason no longer be
the Master Servicer hereunder (including by reason of an Event of Default), the
Trustee or its designee shall thereupon assume all of the rights and obligations
of the Master Servicer hereunder arising thereafter (except that the Trustee
shall not be (i) liable for losses of the Master Servicer pursuant to Section
3.10 hereof or any acts or omissions of the predecessor Master Servicer
hereunder, (ii) obligated to make Advances if it is prohibited from doing so by
applicable law, (iii) obligated to effectuate repurchases or substitutions of
Mortgage Loans hereunder, including pursuant to Section 2.02 or 2.03 hereof,
(iv) responsible for expenses of the Master Servicer pursuant to Section 2.03 or
(v) deemed to have made any representations and warranties hereunder, including
pursuant to Section 2.03 or the first paragraph of Section 6.02 hereof). If the
Master Servicer shall for any reason no longer be the Master Servicer (including
by reason of any Event of Default), the Trustee (or any other successor
servicer) may, at its option, succeed to any rights and obligations of the
Master Servicer under any subservicing agreement in accordance with the terms
thereof; provided that the Trustee (or any other successor servicer) shall not
incur any liability or have any obligations in its capacity as servicer under a
subservicing agreement arising prior to the date of such succession unless it
expressly elects to succeed to the rights and obligations of the Master Servicer
thereunder; and the Master Servicer shall not thereby be relieved of any
liability or obligations under the subservicing agreement arising prior to the
date of such succession.

         The Master Servicer shall, upon request of the Trustee, but at the
expense of the Master Servicer, deliver to the assuming party all documents and
records relating to each subservicing agreement and the Mortgage Loans then
being serviced thereunder and an accounting of amounts collected held by it and
otherwise use its best efforts to effect the orderly and efficient transfer of
the subservicing agreement to the assuming party.

         Section 3.05 Collection of Mortgage Loan Payments; Certificate Account;
                      Distribution Account; Seller Shortfall Interest
                      Requirement.

         (a) The Master Servicer shall make reasonable efforts in accordance
with customary and usual standards of practice of prudent mortgage lenders in
the respective states in which the Mortgaged Properties are located to collect
all payments called for under the terms and provisions of the Mortgage Loans to
the extent such procedures shall be consistent with this Agreement and the terms
and provisions of any related Required Insurance Policy. Consistent with the
foregoing, the Master Servicer may in its discretion (i) waive any late payment
charge or any Prepayment Charge or penalty interest in connection with the
prepayment of a Mortgage Loan and (ii) extend the due dates for payments due on
a Mortgage Note for a period not greater than 270 days. In the event of any such
arrangement, the Master Servicer shall make Advances on the related Mortgage
Loan during the scheduled period in accordance with the amortization schedule of
such Mortgage Loan without modification thereof by reason of such arrangements.
The Master Servicer shall not be required to institute or join in litigation
with respect to collection of any payment (whether under a Mortgage, Mortgage
Note or otherwise or against any public or governmental authority with respect
to a taking or condemnation) if it reasonably believes that enforcing the
provision of the Mortgage or other instrument pursuant to which such payment is
required is prohibited by applicable law.

         (b) The Master Servicer shall establish and maintain a Certificate
Account into which the Master Servicer shall deposit or cause to be deposited on
a daily basis within two Business Days of receipt, except as otherwise
specifically provided herein, the following payments and collections remitted by
Subservicers or received by it in respect of Mortgage Loans subsequent to the
Cut-off Date (other than in respect of principal and interest due on the
Mortgage Loans before the Cut-off Date) and the following amounts required to be
deposited hereunder:

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

                  (ii) all payments on account of interest on the Mortgage Loans
         net of the related Servicing Fee permitted under Section 3.15, other
         than interest accrued on the Mortgage Loans prior to the Cut-off Date,
         and the Certificate Account Deposit;

                  (iii) all Insurance Proceeds and Liquidation Proceeds, other
         than proceeds to be applied to the restoration or repair of the
         Mortgaged Property or released to the Mortgagor in accordance with the
         Master Servicer's normal servicing procedures;

                  (iv) all Compensating Interest;

                  (v) any amount required to be deposited by the Master Servicer
         pursuant to Section 3.05(f) in connection with any losses on Permitted
         Investments;



                                       80

<PAGE>



                  (vi) any amounts required to be deposited by the Master
         Servicer pursuant to Section 3.10 hereof;

                  (vii) the Purchase Price and any Substitution Adjustment
         Amount;

                  (viii) all Advances made by the Master Servicer pursuant to
         Section 4.01;

                  (ix) the Seller Shortfall Interest Requirement;

                  (x) all Prepayment Charges collected; and

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

         The foregoing requirements for remittance by the Master Servicer into
the Certificate Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, payments in the nature of
prepayment penalties, late payment charges or assumption fees, if collected,
need not be remitted by the Master Servicer. In the event that the Master
Servicer shall remit any amount not required to be remitted and not otherwise
subject to withdrawal pursuant to Section 3.08 hereof, it may at any time
withdraw or direct the institution maintaining the Certificate Account, to
withdraw such amount from the Certificate Account, any provision herein to the
contrary notwithstanding. Such withdrawal or direction may be accomplished by
delivering written notice thereof to the institution maintaining the Certificate
Account, that describes the amounts deposited in error in the Certificate
Account. The Master Servicer shall maintain adequate records with respect to all
withdrawals made pursuant to this Section. All funds deposited in the
Certificate Account shall be held in trust for the Certificateholders until
withdrawn in accordance with Section 3.08.

         (c) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Distribution Account. The Trustee shall, promptly upon
receipt, deposit in the Distribution Account and retain therein the following:

                  (i) the aggregate amount remitted by the Master Servicer
         pursuant to the second paragraph of Section 3.08(a); and

                  (ii) any amount required to be deposited by the Master
         Servicer pursuant to Section 3.05(f) in connection with any losses on
         Permitted Investments.

         The foregoing requirements for remittance by the Master Servicer and
deposit by the Trustee into the Distribution Account shall be exclusive. In the
event that the Master Servicer shall remit any amount not required to be
remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time direct the Trustee to withdraw such amount from the
Distribution Account, any provision herein to the contrary notwithstanding. Such
direction may be accomplished by delivering a written notice to the Trustee that
describes the amounts deposited in error in the


                                       81

<PAGE>



Distribution Account. All funds deposited in the Distribution Account shall be
held by the Trustee in trust for the Certificateholders until disbursed in
accordance with this Agreement or withdrawn in accordance with Section 3.08. In
no event shall the Trustee incur liability for withdrawals from the Distribution
Account at the direction of the Master Servicer.

         (d) No later than 1:00 p.m. Pacific time on the Business Day prior to
the Master Servicer Advance Date in September 2003, the Seller shall remit to
the Master Servicer, and the Master Servicer shall deposit in the Certificate
Account, the Seller Shortfall Interest Requirement (if any) for such Master
Servicer Advance Date.

         (e) On the Closing Date, the Seller shall deposit into the Distribution
Account an amount equal to $548.68. The Trustee shall allocate such amount to
Loan Group 1 and Loan Group 2 based on the Stated Principal Balances of each
Loan Group and distribute such amount to the Certificates on the first
Distribution Date pursuant to Section 4.04(d).

         (f) Each institution that maintains the Certificate Account or the
Distribution Account shall invest the funds in each such account, as directed by
the Master Servicer, in Permitted Investments, which shall mature not later than
(x) in the case of the Certificate Account, the second Business Day next
preceding the related Distribution Account Deposit Date (except that if such
Permitted Investment is an obligation of the institution that maintains such
Certificate Account, then such Permitted Investment shall mature not later than
the Business Day next preceding such Distribution Account Deposit Date) and (y)
in the case of the Distribution Account, the Business Day immediately preceding
the first Distribution Date that follows the date of such investment (except
that if such Permitted Investment is an obligation of the institution that
maintains such Distribution Account, then such Permitted Investment shall mature
not later than such Distribution Date), in each case, shall not be sold or
disposed of prior to its maturity. All such Permitted Investments shall be made
in the name of the Trustee, for the benefit of the Certificateholders. In the
case of the Certificate Account and the Distribution Account, all income and
gain net of any losses realized from any such investment shall be for the
benefit of the Master Servicer as servicing compensation and shall be remitted
to it monthly as provided herein, all income and gain net of any losses realized
from any such investment shall be for the benefit of the Seller and shall be
remitted to the Seller as provided herein. The amount of any losses incurred in
the Certificate Account or the Distribution Account in respect of any such
investments shall be deposited by the Master Servicer in the Certificate Account
or paid to the Trustee for deposit into the Distribution Account out of the
Master Servicer's own funds immediately as realized. Any losses incurred in the
Carryover Reserve Fund in respect of any such investments shall be charged
against amounts on deposit in the Carryover Reserve Fund (or such investments)
immediately as realized. The Trustee shall not be liable for the amount of any
loss incurred in respect of any investment or lack of investment of funds held
in the Certificate Account, the Distribution Account, the Carryover Reserve Fund
and made in accordance with this Section 3.05 (or in the case of the Carryover
Reserve Fund, Section 4.08).

         (g) The Master Servicer shall give at least 30 days advance notice to
the Trustee, the Seller, each Rating Agency and the Depositor of any proposed
change of location of the Certificate

Account prior to any change thereof. The Trustee shall give at least 30 days
advance notice to the Master Servicer, the Seller, each Rating Agency and the
Depositor of any proposed change of the location of the Distribution Account,
the Carryover Reserve Fund prior to any change thereof.

         (h) The Trustee shall establish and maintain, on behalf of the Class P
Certificateholders, the Class P Distribution Account. Funds in the Class P
Distribution Account shall be held in trust for the Class P Certificateholders
for the uses and purposes set forth in this Agreement. Such funds may not be
invested.

         Section 3.06 Collection of Taxes, Assessments and Similar Items; Escrow
                      Accounts.

         To the extent required by the related Mortgage Note, the Master
Servicer shall establish and maintain one or more accounts (each, an "Escrow
Account") and deposit and retain therein all collections from the Mortgagors (or
advances by the Master Servicer) for the payment of taxes, assessments, hazard
insurance premiums or comparable items for the account of the Mortgagors.
Nothing herein shall require the Master Servicer to compel a Mortgagor to
establish an Escrow Account in violation of applicable law.

         Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to reimburse
the Master Servicer out of related collections for any payments made pursuant to
Sections 3.01 hereof (with respect to taxes and assessments and insurance
premiums) and 3.10 hereof (with respect to hazard insurance), to refund to any
Mortgagors any sums as may be determined to be overages, to pay interest, if
required by law or the terms of the related Mortgage or Mortgage Note, to
Mortgagors on balances in the Escrow Account or to clear and terminate the
Escrow Account at the termination of this Agreement in accordance with Section
9.01 hereof. The Escrow Accounts shall not be a part of the Trust Fund.

         Section 3.07 Access to Certain Documentation and Information Regarding
                      the Mortgage Loans.

         The Master Servicer shall afford the Depositor and the Trustee
reasonable access to all records and documentation regarding the Mortgage Loans
and all accounts, insurance policies and other matters relating to this
Agreement, such access being afforded without charge, but only upon reasonable
request and during normal business hours at the offices of the Master Servicer
designated by it.

         Upon reasonable advance notice in writing if required by federal
regulation, the Master Servicer will provide to each Certificateholder or
Certificate Owner that is a savings and loan association, bank or insurance
company certain reports and reasonable access to information and documentation
regarding the Mortgage Loans sufficient to permit such Certificateholder or
Certificate Owner to comply with applicable regulations of the OTS or other
regulatory authorities with respect to investment in the Certificates; provided
that the Master Servicer shall be entitled to


                                       83

<PAGE>



be reimbursed by each such Certificateholder or Certificate Owner for actual
expenses incurred by the Master Servicer in providing such reports and access.

         Section 3.08 Permitted Withdrawals from the Certificate Account,

         purpose, Liquidation Proceeds) that represent late recoveries of
         payments of principal and/or interest on such particular Mortgage
         Loan(s) in respect of which any such Advance was made;

                  (iii) to reimburse each of the Master Servicer and the Trustee

                  (v) to pay the Master Servicer any unpaid Servicing Fees and

                  (vi) to pay to the Seller, the Depositor or the Master
         Servicer, as applicable, with respect to each Mortgage Loan or property

                  (vii) to reimburse the Seller, the Master Servicer or the
         Depositor for expenses incurred by any of them in connection with the

                  (viii) to withdraw pursuant to Section 3.05 any amount

         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 Certificate Account pursuant to subclauses (i), (ii), (iv),
(v) and (vi) above. Prior to making any withdrawal from the Certificate Account
pursuant to subclause (iii), the Master Servicer shall deliver to the Trustee an
Officer's Certificate of a Servicing Officer indicating the amount of any
previous Advance determined by the Master Servicer to be a Nonrecoverable
Advance and identifying the related Mortgage Loan(s), and their respective
portions of such Nonrecoverable Advance.

         (b) The Trustee shall withdraw funds from the Distribution Account for
distribution to the Certificateholders in the manner specified in this Agreement
(and to withhold from the amounts so withdrawn, the amount of any taxes that it
is authorized to retain pursuant to the last paragraph of Section 8.11). In
addition, the Trustee may from time to time make withdrawals from the
Distribution Account for the following purposes:

                  (i) to pay to the Master Servicer, as additional servicing
         compensation, earnings on or investment income with respect to funds in
         or credited to the Distribution Account;

                  (ii) to pay to the Co-Trustee, for payment to the Mortgage

                  (iii) to pay the Trustee the Trustee Fee on each Distribution

<PAGE>



                  (v) to reimburse the Trustee for any unreimbursed Advances
         made by it pursuant to Section 4.01(b) hereof, such right of
         reimbursement pursuant to this subclause (iv) being limited to (x)
         amounts received on the related Mortgage Loan(s) in respect of which
         any such Advance was made and (y) amounts not otherwise reimbursed to
         the Trustee pursuant to Section 3.08(a)(ii) hereof;

                  (vi) to reimburse the Trustee for any Nonrecoverable Advance
         previously made by the Trustee pursuant to Section 4.01(b) hereof, such
         right of reimbursement pursuant to this subclause (v) being limited to
         amounts not otherwise reimbursed to the Trustee pursuant to Section
         3.08(a)(iii) hereof; and

                  (vii) to clear and terminate the Distribution Account upon
         termination of the Agreement pursuant to Section 9.01 hereof.

         The Co-Trustee shall pay the Mortgage Insurance Premium to The Mortgage

Wisconsin Avenue, Milwaukee, Wisconsin 53201, ABA #075000022 for the Account of
Mortgage Guaranty Insurance Corporation Account #112663706, Attention: Premium
Pay - Deal #1565 3147643044 (2003-BC4).

         (c) The Trustee shall withdraw funds from the Carryover Reserve Fund
for distribution to the Certificateholders in the manner specified in this
Agreement (and to withhold from the amounts so withdrawn, the amount of any
taxes that it is authorized to retain pursuant to the last paragraph of Section
8.11). In addition, the Trustee may from time to time make withdrawals from the
Carryover Reserve Fund for the following purposes:

                  (i) to withdraw pursuant to Section 3.05 any amount deposited
         in the Carryover Reserve Fund and not required to be deposited therein;
         and

                  (ii) to clear and terminate the Carryover Reserve Fund upon
         termination of the Agreement pursuant to Section 9.01 hereof.

         Section 3.09 [Reserved.]

         Section 3.10 Maintenance of Hazard Insurance.

         The Master Servicer shall cause to be maintained, for each Mortgage
Loan, hazard insurance with extended coverage in an amount that is at least
equal to the lesser of (i) the maximum insurable value of the improvements
securing such Mortgage Loan and (ii) the greater of (a) the outstanding
principal balance of the Mortgage Loan and (b) an amount such that the proceeds
of such policy shall be sufficient to prevent the related Mortgagor and/or
mortgagee from becoming a co-insurer. Each such policy of standard hazard
insurance shall contain, or have an accompanying endorsement that contains, a
standard mortgagee clause. The Master Servicer shall also cause flood insurance
to be maintained on property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage


                                       86

<PAGE>



Loan, to the extent described below. Pursuant to Section 3.05 hereof, any
amounts collected by the Master Servicer under any such policies (other than the
amounts to be applied to the restoration or repair of the related Mortgaged
Property or property thus acquired or amounts released to the Mortgagor in
accordance with the Master Servicer's normal servicing procedures) shall be
deposited in the Certificate Account. Any cost incurred by the Master Servicer
in maintaining any such insurance shall not, for the purpose of calculating
monthly distributions to the Certificateholders or remittances to the Trustee
for their benefit, be added to the principal balance of the Mortgage Loan,
notwithstanding that the terms of the Mortgage Loan so permit. Such costs shall
be recoverable by the Master Servicer out of late payments by the related
Mortgagor or out of Liquidation Proceeds to the extent permitted by Section 3.08
hereof. It is understood and agreed that no earthquake or other additional
insurance is to be required of any Mortgagor or maintained on property acquired
in respect of a Mortgage 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 is located at the time of
origination of the Mortgage Loan in a federally designated special flood hazard
area and such area is participating in the national flood insurance program, the
Master Servicer shall cause flood insurance to be maintained with respect to
such Mortgage Loan. Such flood insurance shall be in an amount equal to the
lesser of (i) the original principal balance of the related Mortgage Loan, (ii)
the replacement value of the improvements that are part of such Mortgaged
Property, or (iii) the maximum amount of such insurance available for the
related Mortgaged Property under the Flood Disaster Protection Act of 1973, as
amended.

         Section 3.11 Enforcement of Due-On-Sale Clauses; Assumption Agreements.

         (a) Except as otherwise provided in this Section 3.11(a), when any
property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Master Servicer shall to the extent that it has knowledge of such
conveyance, enforce any due-on-sale clause contained in any Mortgage Note or
Mortgage, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not adversely
affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Master Servicer is not required to exercise
such rights with respect to a Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the
terms and conditions contained in the Mortgage Note and Mortgage related thereto
and the consent of the mortgagee under such Mortgage Note or Mortgage is not
otherwise so required under such Mortgage Note or Mortgage as a condition to
such transfer. In the event that the Master Servicer is prohibited by law from
enforcing any such due-on-sale clause, or if coverage under any Required
Insurance Policy would be adversely affected, or if nonenforcement is otherwise
permitted hereunder, the Master Servicer is authorized, subject to Section
3.11(b), to take or enter into an assumption and modification agreement from or
with the person to whom such property has been or is about to be conveyed,
pursuant to which such person becomes liable under the Mortgage Note and, unless
prohibited by applicable state law, the Mortgagor remains liable thereon,
provided that the Mortgage Loan shall continue to be covered (if so covered
before the Master Servicer enters such agreement) by the applicable Required
Insurance Policies. The Master Servicer, subject to Section 3.11(b), is also
authorized with the prior approval of the insurers under any Required Insurance
Policies to enter


                                       87

<PAGE>



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 Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the
foregoing, the Master Servicer shall not be deemed to be in default under this
Section 3.11(a) by reason of any transfer or assumption that the Master Servicer
reasonably believes it is restricted by law from preventing.

         (b) Subject to the Master Servicer's duty to enforce any due-on-sale
clause to the extent set forth in Section 3.11(a) hereof, in any case in which a
Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person
is to enter into an assumption agreement or modification agreement or supplement
to the Mortgage Note or Mortgage that requires the signature of the Trustee, or
if an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the Mortgage Loan, the Master Servicer shall prepare
and deliver or cause to be prepared and delivered to the Trustee for signature
and shall direct, in writing, the Trustee to execute the assumption agreement
with the Person to whom the Mortgaged Property is to be conveyed and such
modification agreement or supplement to the Mortgage Note or Mortgage or other
instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In connection with any such assumption, no material term of the Mortgage Note
(including, but not limited to, the Mortgage Rate, the amount of the Scheduled
Payment, the Maximum Mortgage Rate, the Minimum Mortgage Rate, the Gross Margin,
the Periodic Rate Cap, the Adjustment Date and any other term affecting the
amount or timing of payment on the Mortgage Loan) may be changed. In addition,
the substitute Mortgagor and the Mortgaged Property must be acceptable to the
Master Servicer in accordance with its underwriting standards as then in effect.
The Master Servicer shall notify the Trustee that any such substitution or
assumption agreement has been completed by forwarding to the Co-Trustee the
original of such substitution or assumption agreement, which in the case of the
original shall be added to the related Mortgage File and shall, for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof. Any fee collected
by the Master Servicer for entering into an assumption or substitution of
liability agreement will be retained by the Master Servicer as additional
servicing compensation.

         Section 3.12 Realization Upon Defaulted Mortgage Loans; Determination
                      of Excess Proceeds and Realized Losses; Repurchase of
                      Certain Mortgage Loans.

         (a) The Master Servicer shall use reasonable efforts to foreclose upon
or otherwise comparably convert the ownership of properties securing such of the
Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion, the Master Servicer shall
follow such practices and procedures as it shall deem necessary or advisable and
as shall be normal and usual in its general mortgage servicing activities and
the requirements of the insurer under any Required Insurance Policy; provided
that the Master Servicer shall not be required to expend its own funds in
connection with any foreclosure or towards the restoration of any property
unless it shall determine (i) that such restoration and/or foreclosure will
increase the proceeds of


                                       88

<PAGE>



liquidation of the Mortgage Loan after reimbursement to itself of such expenses
and (ii) that such expenses will be recoverable to it through Liquidation
Proceeds (respecting which it shall have priority for purposes of withdrawals
from the Certificate Account pursuant to Section 3.08 hereof). The Master
Servicer shall be responsible for all other costs and expenses incurred by it in
any such proceedings; provided that it shall be entitled to reimbursement
thereof from the proceeds of liquidation of the related Mortgaged Property, as
contemplated in Section 3.08 hereof. If the Master Servicer has knowledge that a
Mortgaged Property that the Master Servicer is contemplating acquiring in
foreclosure or by deed-in-lieu of foreclosure is located within a one-mile
radius of any site with environmental or hazardous waste risks known to the
Master Servicer, the Master Servicer will, prior to acquiring the Mortgaged
Property, consider such risks and only take action in accordance with its
established environmental review procedures.

         With respect to any REO Property, the deed or certificate of sale shall
be taken in the name of the Trustee for the benefit of the Certificateholders
(or the Trustee's nominee on behalf of the Certificateholders). The Trustee's
name shall be placed on the title to such REO Property solely as the Trustee
hereunder and not in its individual capacity. The Master Servicer shall ensure
that the title to such REO Property references this Agreement and the Trustee's
capacity thereunder. Pursuant to its efforts to sell such REO Property, the
Master Servicer shall either itself or through an agent selected by the Master
Servicer protect and conserve such REO Property in the same manner and to such
extent as is customary in the locality where such REO Property is located and
may, incident to its conservation and protection of the interests of the
Certificateholders, rent the same, or any part thereof, as the Master Servicer
deems to be in the best interest of the Master Servicer and the
Certificateholders for the period prior to the sale of such REO Property. The
Master Servicer shall prepare for and deliver to the Trustee a statement with
respect to each REO Property that has been rented showing the aggregate rental
income received and all expenses incurred in connection with the management and
maintenance of such REO Property at such times as is necessary to enable the
Trustee to comply with the reporting requirements of the REMIC Provisions. The
net monthly rental income, if any, from such REO Property shall be deposited in
the Certificate Account no later than the close of business on each
Determination Date. The Master Servicer shall perform the tax reporting and
withholding related to foreclosures, abandonments and cancellation of
indebtedness income as specified by Sections 1445, 6050J and 6050P of the Code
by preparing and filing such tax and information returns, as may be required.

         In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property as
soon as practicable in a manner that maximizes the Liquidation Proceeds, but in
no event later than three years after its acquisition by the Trust Fund or, at
the expense of the Trust Fund, the Master Servicer shall request, more than 60
days prior to the day on which such three-year period would otherwise expire, an
extension of the three-year grace period. In the event the Trustee shall have
been supplied with an Opinion of Counsel (such opinion not to be an expense of
the Trustee) to the effect that the holding by the Trust Fund of such Mortgaged
Property subsequent to such three-year period will not result in the imposition
of taxes on "prohibited transactions" of the Trust Fund as defined in section
860F of the Code or cause the


                                       89

<PAGE>



Trust Fund to fail to qualify as a REMIC at any time that any Certificates are
outstanding, the Trust Fund may continue to hold such Mortgaged Property
(subject to any conditions contained in such Opinion of Counsel) after the
expiration of such three-year period. Notwithstanding any other provision of
this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented
(or allowed to continue to be rented) or otherwise used for the production of
income by or on behalf of the Trust Fund in such a manner or pursuant to any
terms that would (i) cause such Mortgaged Property to fail to qualify as
"foreclosure property" within the meaning of section 860G(a)(8) of the Code or
(ii) subject the Trust Fund to the imposition of any federal, state or local
income taxes on the income earned from such Mortgaged Property under section
860G(c) of the Code or otherwise, unless the Master Servicer has agreed to
indemnify and hold harmless the Trust Fund with respect to the imposition of any
such taxes.

         The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of bringing
such a proceeding. The income earned from the management of any Mortgaged
Properties acquired through foreclosure or other judicial proceeding, net of
reimbursement to the Master Servicer for expenses incurred (including any
property or other taxes) in connection with such management and net of
unreimbursed Servicing Fees, Advances, Servicing Advances and any management fee
paid or to be paid with respect to the management of such Mortgaged Property,
shall be applied to the payment of principal of, and interest on, the related
defaulted Mortgage Loans (with interest accruing as though such Mortgage Loans
were still current) and all such income shall be deemed, for all purposes in
this Agreement, to be payments on account of principal and interest on the
related Mortgage Notes and shall be deposited into the Certificate Account. To
the extent the income received during a Prepayment Period is in excess of the
amount attributable to amortizing principal and accrued interest at the related
Mortgage Rate on the related Mortgage Loan, such excess shall be considered to
be a partial Principal Prepayment for all purposes hereof.

         The Liquidation Proceeds from any liquidation of a Mortgage Loan, net
of any payment to the Master Servicer as provided above, shall be deposited in
the Certificate Account on the next succeeding Determination Date following
receipt thereof for distribution on the related Distribution Date, except that
any Excess Proceeds shall be retained by the Master Servicer as additional
servicing compensation.

         The proceeds of any Liquidated Loan, as well as any recovery resulting
from a partial collection of liquidation proceeds or any income from an REO
Property, will be applied in the following order of priority: first, to
reimburse the Master Servicer for any related unreimbursed Servicing Advances
and Servicing Fees, pursuant to Section 3.08(a)(v) or this Section 3.12; second,
to reimburse the Master Servicer for any unreimbursed Advances, pursuant to
Section 3.08(a)(ii) or this Section 3.12; third, to accrued and unpaid interest
(to the extent no Advance has been made for such amount) on the Mortgage Loan or
related REO Property, at the Net Mortgage Rate to the Due Date occurring in the
month in which such amounts are required to be distributed; and fourth, as a
recovery of principal of the Mortgage Loan.


                                       90

<PAGE>



         (b) On each Determination Date, the Master Servicer shall determine the
respective aggregate amounts of Excess Proceeds and Realized Losses, if any, for
the related Prepayment Period.

         (c) The Master Servicer, in its sole discretion, shall have the right
to elect (by written notice sent to the Trustee) to purchase for its own account
from the Trust Fund any Mortgage Loan that is 150 days or more delinquent at a
price equal to the Purchase Price; provided, however, that the Master Servicer
may only exercise this right on or before the last day of the calendar month in
which such Mortgage Loan became 150 days delinquent (such month, the "Eligible
Repurchase Month"); provided further, that any such Mortgage Loan which becomes
current but thereafter becomes delinquent may be purchased by the Master
Servicer pursuant to this Section in any ensuing Eligible Repurchase Month. The
Purchase Price for any Mortgage Loan purchased hereunder shall be delivered to

of Exhibit N hereto, shall release or cause to be released to the purchaser of
such Mortgage Loan the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the purchaser of such Mortgage
Loan, in each case without recourse, as shall be necessary to vest in the
purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto and
the purchaser of such Mortgage Loan shall succeed to all the Trustee's right,
title and interest in and to such Mortgage Loan and all security and documents
related thereto. Such assignment shall be an assignment outright and not for
security. The purchaser of such Mortgage Loan shall thereupon own such Mortgage
Loan, and all security and documents, free of any further obligation to the
Trustee or the Certificateholders with respect thereto.

         Section 3.13 Co-Trustee to Cooperate; Release of Mortgage Files.

         Upon the payment in full of any Mortgage Loan, or the receipt by the
Master Servicer of a notification that payment in full will be escrowed in a

or the Mortgage or any of the other documents included in the Mortgage File, the
Co-Trustee shall, upon delivery to the Co-Trustee of a Request for Release in
the form of Exhibit M signed by a Servicing Officer, release the Mortgage File
to the Master Servicer. Subject to the further limitations set forth below, the
Master Servicer shall cause the Mortgage File or documents so released to be
returned to the Co-Trustee when the need therefor by the Master Servicer no
longer exists, unless the Mortgage Loan is liquidated and the proceeds thereof
are deposited in the Certificate Account, in which case the Co-Trustee shall
deliver the Request for Release to the Master Servicer.

         If the Master Servicer at any time seeks to initiate a foreclosure
proceeding in respect of any Mortgaged Property as authorized by this Agreement,
the Master Servicer shall deliver or cause to be delivered to the Trustee, for

the Mortgage File or the documents therein were delivered and the purpose or
purposes of such delivery.

                      Servicer to be Held for the Trustee.

         Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Co-Trustee as required by this Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the Master Servicer from time to time and shall account fully to
the Trustee for any funds received by the Master Servicer or that otherwise are
collected by the Master Servicer as Liquidation Proceeds or Insurance Proceeds

Certificate Account, shall be held by the Master Servicer for and on behalf of
the Trust Fund and shall be and remain the sole and exclusive property of the
Trust Fund, subject to the applicable provisions of this Agreement. The Master

Section 3.06), or any funds that otherwise are or may become due or payable to
the Trustee for the benefit of the Certificateholders, to any claim, lien,
security interest, judgment, levy, writ of attachment or other encumbrance, or
assert by legal action or otherwise any claim or right of set off against any

and deduct from any such funds any amounts that are properly due and payable to
the Master Servicer under this Agreement.

not constitute a breach of this Section.

the interest rate cap transactions evidenced by the Cap Contracts to, and shall
cause all of its obligations in respect of each such transaction to be assumed

Carryover Reserve Fund to pay Net Rate Carryover for the Certificates (by
deposit of the amount of any such Net Rate Carryover in the Carryover Reserve

         Section 3.20 Prepayment Charges.

         (a) Notwithstanding anything in this Agreement to the contrary, in the
event of a Principal Prepayment in full or in part of a Mortgage Loan, the
Master Servicer may not waive any Prepayment Charge or portion thereof required
by the terms of the related Mortgage Note unless (i) the Master Servicer
determines that such waiver would maximize recovery of Liquidation Proceeds for
such Mortgage Loan, taking into account the value of such Prepayment Charge, or
(ii) (A) the enforceability thereof is limited (1) by bankruptcy, insolvency,
moratorium, receivership, or other similar law relating to creditors' rights
generally or (2) due to acceleration in connection with a foreclosure or other
involuntary payment, or (B) the enforceability is otherwise limited or
prohibited by applicable law. In the event of a Principal Prepayment in full or
in part with respect to any Mortgage Loan, the Master Servicer shall deliver to
the Trustee an Officer's Certificate substantially in the form of Exhibit T no

Servicer has waived or does not collect all or a portion of a Prepayment Charge
relating to a Principal Prepayment in full or in part due to any action or
omission of the Master Servicer, other than as provided above, the Master
Servicer shall deliver to the Trustee, together with the Principal Prepayment in
full or in part, the amount of such Prepayment Charge (or such portion thereof
as had been waived) for deposit into the Certificate Account (not later than the
immediately succeeding Master Servicer Advance Date, in the case of such
Prepayment Charge) for distribution in accordance with the terms of this
Agreement.

         (b) Upon discovery by the Master Servicer or a Responsible Officer of
the Trustee of a breach of the foregoing subsection (a), the party discovering
the breach shall give prompt written notice to the other parties.

Trustee, as of the Closing Date, that the information in the Prepayment Charge
Schedule (including the attached prepayment charge summary) is complete and
accurate in all material respects at the dates as of which the information is
furnished and each Prepayment Charge is permissible and enforceable in

enforceability thereof is limited due to acceleration in connection with a
foreclosure or other involuntary payment.

         (d) Upon discovery by the Master Servicer or a Responsible Officer of
the Trustee of a breach of the foregoing clause (c) that materially and
adversely affects right of the Holders of the Class P Certificates to any
Prepayment Charge, the party discovering the breach shall give prompt written
notice to the other parties. Within 60 days of the earlier of discovery by the
Master Servicer or receipt of notice by the Master Servicer of breach, the
Master Servicer shall cure the breach in all material respects or shall pay into
the Certificate Account the amount of the Prepayment Charge that would otherwise
be due from the Mortgagor, less any amount representing such Prepayment Charge
previously collected and paid by the Master Servicer into the Certificate
Account.

                                DISTRIBUTIONS AND
                         ADVANCES BY THE MASTER SERVICER

         Section 4.01 Advances.

         (a) The Master Servicer shall determine on or before each Master
Servicer Advance Date whether it is required to make an Advance pursuant to the
definition thereof. If the Master Servicer determines it is required to make an
Advance, it shall, on or before the Master Servicer Advance Date, either (i)
deposit into the Certificate Account an amount equal to the Advance or (ii) make
an appropriate entry in its records relating to the Certificate Account that any
Amount Held for Future Distribution has been used by the Master Servicer in
discharge of its obligation to make any such Advance. Any funds so applied shall
be replaced by the Master Servicer by deposit in the Certificate Account no
later than the close of business on the next Master Servicer Advance Date. The
Master Servicer shall be entitled to be reimbursed from the Certificate Account
for all Advances of its own funds made pursuant to this Section as provided in
Section 3.08. The obligation to make Advances with respect to any Mortgage Loan
shall continue if such Mortgage Loan has been foreclosed or otherwise terminated
and the related Mortgaged Property has not been liquidated.

         (b) If the Master Servicer determines that it will be unable to comply
with its obligation to make the Advances as and when described in the second
sentence of Section 4.01(a), it shall use its best efforts to give written
notice thereof to the Trustee (each such notice a "Trustee Advance Notice"; and
such notice may be given by telecopy), not later than 3:00 P.M., New York time,
on the Business Day immediately preceding the related Master Servicer Advance
Date, specifying the amount that it will be unable to deposit (each such amount
an "Advance Deficiency") and certifying that such Advance Deficiency constitutes
an Advance hereunder and is not a Nonrecoverable Advance. If the Trustee
receives a Trustee Advance Notice on or before 3:30 P.M., New York time on a
Master Servicer Advance Date, the Trustee shall, not later than 3:00 P.M., New
York time, on the related Distribution Date, deposit in the Distribution Account
an amount equal to the Advance Deficiency identified in such Trustee Advance
Notice unless it is prohibited from so doing by applicable law. Notwithstanding
the foregoing, the Trustee shall not be required to make such deposit if the
Trustee shall have received written notification from the Master Servicer that
the Master Servicer has deposited or caused to be deposited in the Certificate
Account an amount equal to such Advance Deficiency. All Advances made by the
Trustee pursuant to this Section 4.01(b) shall accrue interest on behalf of the
Trustee at the Trustee Advance Rate from and including the date such Advances
are made to but excluding the date of repayment, with such interest being an
obligation of the Master Servicer and not the Trust Fund. The Master Servicer
shall reimburse the Trustee for the amount of any Advance made by the Trustee
pursuant to this Section 4.01(b) together with accrued interest, not later than
6:00 P.M., New York time on the Business Day following the related Distribution
Date. In the event that the Master Servicer does not reimburse the Trustee in
accordance with the requirements of the preceding sentence, the Trustee shall
immediately (a) terminate all of the rights and obligations of the Master
Servicer under this Agreement in accordance


                                       97

<PAGE>



with Section 7.01 and (b) subject to the limitations set forth in Section 3.04,
assume all of the rights and obligations of the Master Servicer hereunder.

         (c) The Master Servicer, not later than the close of business on the
second Business Day immediately preceding each Distribution Date, shall deliver
to the Trustee a report (in the form and substance reasonably satisfactory to
the Trustee) that indicates (i) the Mortgage Loans with respect to which the
Master Servicer has determined that the related Scheduled Payments should be
advanced and (ii) the amount of the related Scheduled Payments. The Master
Servicer shall deliver to the Trustee on the related Master Servicer Advance
Date an Officer's Certificate of a Servicing Officer indicating the amount of
any proposed Advance determined by the Master Servicer to be a Nonrecoverable
Advance.

         Section 4.02 Reduction of Servicing Compensation in Connection with
                      Prepayment Interest Shortfalls.

         In the event that any Mortgage Loan is the subject of a Prepayment
Interest Shortfall, the Master Servicer shall, to the extent of one-half of the
Servicing Fee for such Distribution Date, deposit into the Certificate Account,
as a reduction of the Servicing Fee (but not in excess of one-half thereof) for
such Distribution Date, no later than the close of business on the Business Day
immediately preceding such Distribution Date, an amount equal to the Prepayment
Interest Shortfall; and in case of such deposit, the Master Servicer shall not
be entitled to any recovery or reimbursement from the Depositor, the Trustee,
the Trust Fund or the Certificateholders.

         (b) The Trustee shall make withdrawals from the Carryover Reserve Fund

Carryover Reserve Fund shall be distributed to the Holders of the Class C
Certificates in the same manner as if distributed pursuant to Section 4.04(f)
hereof.

         Distribution Date after the distributions made pursuant to clause (i)
         above, allocated as follows:

                  (a) Distributions of principal shall be deemed to be made to
         the REMIC I Regular Interests first, so as to keep the Uncertificated
         Principal Balance of each REMIC I Regular Interest ending with the
         designation "GRP" equal to 0.01% of the aggregate Stated Principal
         Balance of the Mortgage Loans in the related Group; second, to each

         Balance of the Mortgage Loans in the related Group over (y) the
         Certificate Principal Balance of the Class A Certificate in the related
         Group (except that if any such excess is a larger number than in the
         preceding distribution period, the least amount of principal shall be
         distributed to such REMIC I Regular Interests such that the REMIC I
         Subordinated Balance Ratio is maintained); and third, any remaining
         principal to REMIC I Regular Interest LT-XX.

         Section 4.10 [Reserved].

REMIC I Principal Loss Allocation Amount, 98% and 2%, respectively; third, to
the Uncertificated Principal Balances of REMIC I Regular Interest LT-AA, REMIC I
Regular Interest LT-B and REMIC I Regular Interest LT-ZZ, 98%, 1.00% and 1%,
respectively, until the Uncertificated Principal Balances of REMIC I Regular
Interest LT-B has been reduced to zero; fourth to the Uncertificated Principal
Balances of REMIC I Regular Interest LT-AA, REMIC I Regular Interest LT-M6 and
REMIC I Regular Interest LT-ZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Principal Balance of REMIC I Regular Interest LT-M6 has been
reduced to zero; fifth to the Uncertificated Principal Balances of REMIC I
Regular Interest LT-AA, REMIC I Regular Interest LT-M5 and REMIC I Regular
Interest LT-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal
Balance of REMIC I Regular Interest LT-M5 has been reduced to zero; sixth to the
Uncertificated Principal Balances of REMIC I Regular Interest LT-AA, REMIC I

1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular
Interest LT-M2 has been reduced to zero; and eighth sixth to the Uncertificated
Principal Balances of REMIC I Regular Interest LT-AA, REMIC I Regular Interest
LT-M1 and REMIC I Regular Interest LT-ZZ, 98%, 1% and 1%, respectively, until
the Uncertificated Principal Balance of REMIC I Regular Interest LT-M1 has been
reduced to zero.

         (b) The REMIC I Sub WAC Allocation Percentage of all Realized Losses
shall be applied after all distributions have been made on each Distribution
Date first, so as to keep the Uncertificated Principal Balance of each REMIC I
Regular Interest ending with the designation "GRP" equal to 0.01% of the
aggregate Stated Principal Balance of the Mortgage Loans in the related Group;
second, to each REMIC I Regular Interest ending with the designation "SUB," so
that the Uncertificated Principal Balance of each such REMIC I Regular Interest
is equal to 0.01% of the excess of (x) the aggregate Stated Principal Balance of
the Mortgage Loans in the related Group over (y) the Certificate Principal
Balance of the Senior Certificate in the related Group (except that if any such
excess is a larger number than in the preceding distribution period, the least
amount of Realized Losses shall be applied to such REMIC I Regular Interests
such that the REMIC I Subordinated Balance Ratio is maintained); and third, any
remaining Realized Losses shall be allocated to REMIC I Regular Interest LT-XX.

         Section 4.12 Termination of the Mortgage Insurance Policy.

         If on any given date the rating of The Mortgage Insurer's claims-paying
ability is downgraded below and remains below "AA-" from S&P or "Aa3" from

Insurance Policy and the Co-Trustee shall act in accordance with such direction.
The Master Servicer hereby covenants and agrees that it will not direct the
Co-Trustee to exercise its right to terminate the Mortgage Insurance Policy
unless the Co-Trustee obtains a mortgage insurance policy that meets the
following conditions (any such mortgage insurance policy that meets the
following conditions, the "Replacement Mortgage Insurance Policy," and the
issuer of such policy, the "Replacement Mortgage Insurer"): (i) such mortgage
insurance policy must be issued by a mortgage insurer that has a rating with
respect to its claims-paying ability at or above "AA-" from S&P or "Aa3" from
Moody's and (ii) such mortgage insurance policy must cover the Covered Mortgage
Loans outstanding as of such date.

         Section 4.13 The Class P Certificates.

         On the Closing Date, $100 shall be deposited into the Class P
Distribution Account and shall be held in trust for the benefit of the Class P

         (1) The Tax Matters Person Certificate may be issued in a denomination

         The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized 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 Trustee, 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 authentication and delivery. No
Certificate shall be entitled to any benefit under this Agreement, or be valid
for any purpose, unless there appears on such Certificate a certificate of
authentication substantially in the form set forth as attached hereto executed
by the Trustee by manual signature, and such certificate of authentication upon
any Certificate shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication. On the Closing
Date, the


                                       112

Trustee shall authenticate the Certificates to be issued at the written
direction of the Depositor, or any affiliate thereof.

         Section 5.02 Certificate Register; Registration of Transfer and
                      Exchange of Certificates.

         (a) The Trustee shall maintain, or cause to be maintained in accordance
with the provisions of Section 5.09 hereof, a Certificate Register for the Trust
Fund in which, subject to the provisions of subsections (b) and (c) below and to
such reasonable regulations as it may prescribe, the Trustee shall provide for
the registration of Certificates and of Transfers and exchanges of Certificates
as herein provided. Upon surrender for registration of Transfer of any
Certificate, the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Class and of like aggregate Percentage Interest.

         At the option of a Certificateholder, Certificates may be exchanged for
other Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest upon surrender of the Certificates to be
exchanged at the office or agency of the Trustee. Whenever any Certificates are
so surrendered for exchange, the Trustee shall execute, authenticate, and
deliver the Certificates that the Certificateholder making the exchange is
entitled to receive. Every Certificate presented or surrendered for registration
of Transfer or exchange shall be accompanied by a written instrument of Transfer
in form satisfactory to the Trustee duly executed by the holder thereof or his
attorney duly authorized in writing.

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

         All Certificates surrendered for registration of Transfer or exchange
shall be canceled and subsequently destroyed by the Trustee in accordance with
the Trustee's customary procedures.

         (b) No Transfer of a Private Certificate shall be made unless such
Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a transfer is to be made in reliance upon an exemption
from the Securities Act and such state securities laws, in order to assure
compliance with the Securities Act and such state securities laws, the
Certificateholder desiring to effect such Transfer and such Certificateholder's
prospective transferee shall each certify to the Trustee in writing the facts
surrounding the Transfer in substantially the forms set forth in Exhibit J (the
"Transferor Certificate") and (i) deliver a letter in substantially the form of
either Exhibit K (the "Investment Letter") or Exhibit L (the "Rule 144A Letter")
or (ii) there shall be delivered to the Trustee at the expense of the
Certificateholder desiring to effect such transfer an Opinion of Counsel that
such Transfer may be made pursuant to an exemption from the Securities Act. The
Depositor shall provide to any Holder of a Private Certificate and any
prospective transferee designated by any such Holder, information regarding the
related Certificates and the Mortgage Loans and such other


                                       113

<PAGE>



information as shall be necessary to satisfy the condition to eligibility set
forth in Rule 144A(d)(4) for transfer of any such Certificate without
registration thereof under the Securities Act pursuant to the registration
exemption provided by Rule 144A. The Trustee, the Co-Trustee and the Master
Servicer shall cooperate with the Depositor in providing the Rule 144A
information referenced in the preceding sentence, including providing to the
Depositor such information regarding the Certificates, the Mortgage Loans and
other matters regarding the Trust Fund as the Depositor shall reasonably request
to meet its obligation under the preceding sentence. Each Holder of a Private
Certificate desiring to effect such Transfer shall, and does hereby agree to,
indemnify the Trustee, the Co-Trustee, the Depositor, the Seller and the Master
Servicer against any liability that may result if the Transfer is not so exempt
or is not made in accordance with such federal and state laws.

         No Transfer of an ERISA-Restricted Certificate or a Subordinate
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 (in the event such Certificate is a
Private Certificate that is a Definitive Certificate, such requirement is
satisfied only by the Trustee's receipt of a representation letter from the
transferee substantially in the form of Exhibit K or Exhibit L, or in the event
such Certificate is a Class A-R Certificate, such requirement is satisfied only
by the Trustee's receipt of a representation letter from the transferee
substantially in the form of Exhibit I), to the effect that such transferee is
not an employee benefit plan or arrangement subject to Section 406 of ERISA or a
plan or arrangement subject to Section 4975 of the Code, nor a Person acting on
behalf of any such plan or arrangement or using the assets of any such plan or
arrangement to effect such transfer, or (ii) in the case of the Subordinate
Certificates (A) it has acquired and is holding such Certificate in reliance on
the Underwriters' Exemption and that it understands that there are certain
conditions to the availability of the Underwriters' Exemption, including that
the Certificate must be rated, at the time of purchase, not less than "BBB-" or
its equivalent by one of the Rating Agencies or (B) 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 the
conditions of Sections I and III of PTCE 95-60 have been satisfied or (iii) in
the case of any ERISA-Restricted 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, for the benefit of the
Trustee, the Seller, the Depositor, the Co-Trustee and the Master Servicer, and
on which they may rely, which opinion of counsel shall not be an expense of
either the Trustee or the Trust Fund, addressed to the Trustee to the effect
that the purchase and holding of such ERISA-Restricted Certificate is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code
and will not subject the Depositor, the Seller, the Master Servicer or Trustee
to any obligation, or liability (including liabilities or obligations under
ERISA or Section 4975 of the Code) in addition to those expressly undertaken in
this Agreement or to any liability. For purposes of the preceding sentence, with
respect to an ERISA-Restricted Certificate that is not a Book-Entry Certificate
or a Class A-R Certificate, in the event the representation letter


                                       114

<PAGE>



referred to in the preceding sentence is not so furnished, such representation
shall be deemed to have been made to the Trustee by the transferee's (including
an initial acquiror's) acceptance of such ERISA-Restricted Certificate.
Notwithstanding anything else to the contrary herein, any purported transfer of
an ERISA-Restricted Certificate or a Subordinate Certificate to or on behalf of
an employee benefit plan subject to ERISA or 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. Any purported beneficial owner whose
acquisition or holding of the Certificate or interest therein was effected in
violation of the conditions described in this paragraph shall indemnify and hold
harmless the Depositor, the Trustee, the Co-Trustee, the Master Servicer, the
Seller, any Subservicer and the Trust Fund from and against any and all
liabilities, claims, costs or expenses incurred by those parties as a result of
that acquisition or holding.

         To the extent permitted under applicable law (including, but not
limited to, ERISA), the Trustee shall be under no liability to any Person for
any registration of Transfer of any ERISA-Restricted Certificate that is in fact
not permitted by this Section 5.02(b) or for making any payments due on such
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 Transfer was
registered by the Trustee in accordance with the foregoing requirements.

         (c) Each Person who has or who acquires any Ownership Interest in a
Class A-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
the rights of each Person acquiring any Ownership Interest in a Class A-R
Certificate are expressly subject to the following provisions:

                  (i) Each Person holding or acquiring any Ownership Interest in
         a Class A-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 Ownership Interest in a Class A-R Certificate may be
         registered on the Closing Date or thereafter transferred, and the
         Trustee shall not register the Transfer of any Class A-R Certificate
         unless, in addition to the representation letters required to be
         delivered to the Trustee under subparagraph (b) above, the Trustee
         shall have been furnished with an affidavit (a "Transfer Affidavit") of
         the initial owner or the proposed transferee in the form attached
         hereto as Exhibit I.

                  (iii) Each Person holding or acquiring any Ownership Interest
         in a Class A-R Certificate shall agree (A) to obtain a Transfer
         Affidavit from any other Person to whom such Person attempts to
         Transfer its Ownership Interest in a Class A-R Certificate, (B) to
         obtain a Transfer Affidavit from any Person for whom such Person is
         acting as nominee, trustee or agent in connection with any Transfer of
         a Class A-R Certificate and (C) not to Transfer its Ownership Interest
         in a Class A-R Certificate or to cause the Transfer of an Ownership
         Interest in a Class A-R Certificate to any other Person if it has
         actual knowledge that such Person is not a Permitted Transferee.

                  (iv) Any attempted or purported Transfer of any Ownership
         Interest in a Class A-R Certificate in violation of the provisions of
         this Section 5.02(c) shall be absolutely null and void and shall vest
         no rights in the purported Transferee. If any purported transferee
         shall become a Holder of a Class A-R Certificate in violation of the
         provisions of this Section 5.02(c), then the last preceding Permitted
         Transferee shall be restored to all rights as Holder thereof
         retroactive to the date of registration of Transfer of such Class A-R
         Certificate. The Trustee shall be under no liability to any Person for
         any registration of Transfer of a Class A-R Certificate that is in fact
         not permitted by Section 5.02(b) and this Section 5.02(c) or for making
         any payments due on such 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 Transfer was registered after receipt of
         the related Transfer Affidavit, Transferor Certificate and either the
         Rule 144A Letter or the Investment Letter. The Trustee shall be
         entitled but not obligated to recover from any Holder of a Class A-R
         Certificate that was in fact not a Permitted Transferee at the time it
         became a Holder or, at such subsequent time as it became other than a
         Permitted Transferee, all payments made on such Class A-R Certificate
         at and after either such time. Any such payments so recovered by the
         Trustee shall be paid and delivered by the Trustee to the last
         preceding Permitted Transferee of such Certificate.

                  (v) The Depositor shall use its best efforts to make
         available, upon receipt of written request from the Trustee, all
         information necessary to compute any tax imposed under Section 860E(e)
         of the Code as a result of a Transfer of an Ownership Interest in a
         Class A-R Certificate to any Holder who is not a Permitted Transferee.

         The restrictions on Transfers of a Class A-R Certificate set forth in
this Section 5.02(c) shall cease to apply (and the applicable portions of the
legend on a Class A-R Certificate may be deleted) with respect to Transfers
occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion
of Counsel shall not be an expense of the Trust Fund, the Trustee, the Seller or
the Master Servicer, to the effect that the elimination of such restrictions
will not cause any REMIC hereunder to fail to qualify as a REMIC at any time
that the Certificates are outstanding or result in the imposition of any tax on
the Trust Fund, a Certificateholder or another Person. Each Person holding or
acquiring any Ownership Interest in a Class A-R Certificate hereby consents to
any amendment of this Agreement that, based on an Opinion of Counsel furnished
to the Trustee, is reasonably necessary (a) to ensure that the record ownership
of, or any beneficial interest in, a Class A-R Certificate is not transferred,
directly or indirectly, to a Person that is not a Permitted Transferee and (b)
to provide for a means to compel the Transfer of a Class A-R Certificate that is
held by a Person that is not a Permitted Transferee to a Holder that is a
Permitted Transferee.

         (d) The preparation and delivery of all representation letters and
opinions referred to above in this Section 5.02 in connection with any Transfers
shall be at the expense of the parties to such Transfers.

         Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

         If (a) any mutilated Certificate is surrendered to the Trustee, or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate and of the ownership thereof and (b) there is delivered to
the Master Servicer and the Trustee 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 that such Certificate has been acquired by a bona fide purchaser,
the Trustee shall execute, authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate
of like Class, tenor and Percentage Interest. In connection with the issuance of
any new Certificate under this Section 5.03, the Trustee 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) connected therewith. Any replacement Certificate issued
pursuant to this Section 5.03 shall constitute complete and indefeasible
evidence of ownership in the Trust Fund, as if originally issued, whether or not
the lost, stolen or destroyed Certificate shall be found at any time. All
Certificates surrendered to the Trustee under the terms of this Section 5.03
shall be canceled and destroyed by the Trustee in accordance with its standard
procedures without liability on its part.

         Section 5.04 Persons Deemed Owners.

         The Master Servicer, the Trustee and any agent of the Master Servicer
or the Trustee may treat the person in whose name any Certificate is registered
as the owner of such Certificate for the purpose of receiving distributions as
provided in this Agreement and for all other purposes whatsoever, and neither
the Master Servicer, the Trustee nor any agent of the Master Servicer or the
Trustee shall be affected by any notice to the contrary.

         Section 5.05 Access to List of Certificateholders' Names and Addresses.

         If three or more Certificateholders and/or Certificate Owners (a)
request such information in writing from the Trustee, (b) state that such
Certificateholders and/or Certificate Owners desire to communicate with other
Certificateholders and/or Certificate Owners with respect to their rights under
this Agreement or under the Certificates, and (c) provide a copy of the
communication that such Certificateholders and/or Certificate Owners propose to
transmit or if the Depositor or Master Servicer shall request such information
in writing from the Trustee, then the Trustee shall, within ten Business Days
after the receipt of such request, provide the Depositor, the Master Servicer or
such Certificateholders and/or Certificate Owners at such recipients' expense
the most recent list of the Certificateholders and/or Certificate Owners of the
Trust Fund held by the Trustee, if any. The Depositor and every
Certificateholder or Certificate Owner, by receiving and holding a Certificate,
agree that the Trustee shall not be held accountable by reason of the disclosure
of any such information as to the list of the Certificateholders hereunder,
regardless of the source from which such information was derived.

         Section 5.06 Book-Entry Certificates.

         The Regular Certificates, upon original issuance, shall be issued in
the form of one or more typewritten Certificates representing the Book-Entry
Certificates, to be delivered to the Depository by or on behalf of the
Depositor. Such Certificates shall initially be registered on the Certificate
Register in the name of the Depository or its nominee, and no Certificate Owner
of such Certificates will receive a definitive certificate representing such
Certificate Owner's interest in such Certificates, except as provided in Section
5.08. Unless and until definitive, fully registered Certificates ("Definitive
Certificates") have been issued to the Certificate Owners of such Certificates
pursuant to Section 5.08:

         (a) the provisions of this Section shall be in full force and effect;

         (b) the Depositor, the Seller, the Master Servicer and the Trustee may
deal with the Depository and the Depository Participants for all purposes
(including the making of distributions) as the authorized representative of the
respective Certificate Owners of such Certificates;

         (c) registration of the Book-Entry Certificates may not be transferred
by the Trustee except to another Depository;

         (d) the rights of the respective Certificate Owners of such
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of such Certificates and the Depository and/or the Depository
Participants. Pursuant to the Depository Agreement, unless and until Definitive
Certificates are issued pursuant to Section 5.08, the Depository will make
book-entry transfers among the Depository Participants and receive and transmit
distributions of principal and interest on the related Certificates to such
Depository Participants;

         (e) the Depository may collect its usual and customary fees, charges
and expenses from its Depository Participants;

         (f) the Trustee may rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its Depository
Participants; and

         (g) to the extent that the provisions of this Section conflict with any
other provisions of this Agreement, the provisions of this Section shall
control.

         For purposes of any provision of this Agreement requiring or permitting
actions with the consent of, or at the direction of, Certificateholders
evidencing a specified percentage of the aggregate unpaid principal amount of
any Class of Certificates, such direction or consent may be given by Certificate
Owners (acting through the Depository and the Depository Participants) owning
Book-Entry Certificates evidencing the requisite percentage of principal amount
of such Class of Certificates.

         Section 5.07      Notices to Depository.

         Whenever any notice or other communication is required to be given to
Certificateholders of the Class with respect to which Book-Entry Certificates
have been issued, unless and until Definitive Certificates shall have been
issued to the related Certificate Owners, the Trustee shall give all such
notices and communications to the Depository.

         Section 5.08      Definitive Certificates.

         If, after Book-Entry Certificates have been issued with respect to any
Certificates, (a) the Depositor advises the Trustee that the Depository is no
longer willing or able to discharge properly its responsibilities under the
Depository Agreement with respect to such Certificates and the Trustee or the
Depositor is unable to locate a qualified successor, (b) the Depositor, at its
sole option, advises the Trustee that it elects to terminate the book-entry
system with respect to such Certificates through the Depository or (c) after the
occurrence and continuation of an Event of Default, Certificate Owners of such
Book-Entry Certificates having not less than 51% of the Voting Rights evidenced
by any Class of Book-Entry Certificates advise the Trustee and the Depository in
writing through the Depository Participants that the continuation of a
book-entry system with respect to Certificates of such Class through the
Depository (or its successor) is no longer in the best interests of the
Certificate Owners of such Class, then the Trustee shall notify all Certificate
Owners of such Certificates, through the Depository, of the occurrence of any
such event and of the availability of Definitive Certificates to Certificate
Owners of such Class requesting the same. The Depositor shall provide the
Trustee with an adequate inventory of certificates to facilitate the issuance
and transfer of Definitive Certificates. Upon surrender to the Trustee of any
such Certificates by the Depository, accompanied by registration instructions
from the Depository for registration, the Trustee shall authenticate and deliver
such Definitive Certificates. Neither the Depositor nor the Trustee shall be
liable for any delay in delivery of such instructions and each may conclusively
rely on, and shall be protected in relying on, such instructions. Upon the
issuance of such Definitive Certificates, all references herein to obligations
imposed upon or to be performed by the Depository shall be deemed to be imposed
upon and performed by the Trustee, to the extent applicable with respect to such
Definitive Certificates and the Trustee shall recognize the Holders of such
Definitive Certificates as Certificateholders hereunder.

         Section 5.09      Maintenance of Office or Agency.

         The Trustee will maintain or cause to be maintained at its expense an
office or offices or agency or agencies in New York City where Certificates may
be surrendered for registration of transfer or exchange. The Trustee initially
designates its offices at 101 Barclay Street, New York, New York 10286,
Attention: Corporate Trust MBS Administration, as offices for such purposes. The
Trustee will give prompt written notice to the Certificateholders of any change
in such location of any such office or agency.

respectively imposed upon and undertaken by them herein.

         Section 6.02 Merger or Consolidation of the Depositor, the Master
                      Servicer or the Seller.

         Each of the Depositor and the Seller will keep in full effect its
existence, rights and franchises as a corporation under the laws of the United
States or under the laws of one of the states thereof and will each obtain and
preserve its qualification to do business as a foreign corporation in each
jurisdiction in which such qualification is or shall be necessary to protect the
validity and enforceability of this Agreement, or any of the Mortgage Loans and
to perform its duties under this Agreement. The Master Servicer will keep in
effect its existence, rights and franchises as a limited partnership under the
laws of the United States or under the laws of one of the states thereof and
will obtain and preserve its qualification or registration to do business as a
foreign partnership in each jurisdiction in which such qualification or
registration is or shall be necessary to protect the validity and enforceability
of this Agreement or any of the Mortgage Loans and to perform its duties under
this Agreement.

         Any Person into which the Depositor, the Master Servicer or the Seller
may be merged or consolidated, or any Person resulting from any merger or
consolidation to which the Depositor, the Master Servicer or the Seller shall be
a party, or any person succeeding to the business of the Depositor, the Master
Servicer or the Seller, shall be the successor of the Depositor, the Master
Servicer or the Seller, 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 that the successor or
surviving Person to the Master Servicer shall be qualified to service mortgage
loans on behalf of Fannie Mae or Freddie Mac.

         Section 6.03 Limitation on Liability of the Depositor, the Seller, the
                      Master Servicer and Others.

         None of the Depositor, the Seller, the Master Servicer or any of the

Master Servicer shall be under any liability to the Trust Fund or the
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to this Agreement, or for errors in judgment;
provided that this provision shall not protect the Depositor, the Seller, the
Master Servicer or any such Person against any breach of representations or
warranties made by it herein or protect the Depositor, the Seller, the Master
Servicer or any such Person from any liability that would otherwise be imposed
by reasons


                                       120

<PAGE>



of willful misfeasance, bad faith or gross negligence in the performance of
duties or by reason of reckless disregard of obligations and duties hereunder.
The Depositor, the Seller, the Master Servicer and any director, officer,
employee or agent of the Depositor, the Seller or 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 Depositor,

Trust Fund and held harmless against any loss, liability or expense incurred in
connection with any audit, controversy or judicial proceeding relating to a

reckless disregard of obligations and duties hereunder. None of the Depositor,
the Seller or the Master Servicer shall be under any obligation to appear in,
prosecute or defend any legal action that is not incidental to its respective
duties hereunder and that in its opinion may involve it in any expense or
liability; provided that any of the Depositor, the Seller or the Master Servicer
may, in its discretion undertake any such action that it may deem necessary or
desirable in respect of this Agreement and the rights and duties of the parties
hereto and interests of the Trustee and the Certificateholders hereunder. In
such event, the legal expenses and costs of such action and any liability

         The Master Servicer shall not resign from the obligations and duties
hereby imposed on it except upon determination that its duties hereunder are no
longer permissible under applicable law. 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. No such resignation shall become
effective until the Trustee or a successor servicer to such appointment shall
have assumed the Master Servicer's responsibilities, duties, liabilities and
obligations hereunder.

         Section 6.05      Errors and Omissions Insurance; Fidelity Bonds.

         The Master Servicer shall, for so long as it acts as servicer under
this Agreement, obtain and maintain in force (a) a policy or policies of

persons performing servicing for mortgage loans purchased by Fannie Mae or
Freddie Mac. In the event that any such policy or bond ceases to be in effect,
the Master Servicer shall use its reasonable best efforts to obtain a comparable

                                   ARTICLE VII

                     DEFAULT; TERMINATION OF MASTER SERVICER

         Section 7.01 Events of Default.

         "Event of Default," wherever used herein, means any one of the
following events:

         (i) any failure by the Master Servicer to deposit in the Certificate
Account or the Distribution Account or remit to the Trustee any payment
(excluding a payment required to be made under Section 4.01 hereof) required to
be made under the terms of this Agreement, which failure shall continue
unremedied for five calendar days and, with respect to a payment required to be
made under Section 4.01 hereof, for one Business Day, after the date on which
written notice of such failure shall have been given to the Master Servicer by
the Trustee, the Seller or the Depositor, or to the Trustee and the Master
Servicer by the Holders of Certificates evidencing not less than 25% of the
Voting Rights evidenced by the Certificates; or

         (ii) any failure by the Master Servicer to observe or perform in any
material respect any other of the covenants or agreements on the part of the
Master Servicer contained in this Agreement or any representation or warranty
shall prove to be untrue, which failure or breach shall continue unremedied for
a period of 60 days after the date on which written notice of such failure shall
have been given to the Master Servicer by the Trustee or the Depositor, or to
the Trustee by the Holders of Certificates evidencing not less than 25% of the
Voting Rights evidenced by the Certificates; provided that the sixty-day cure
period shall not apply to the initial delivery of the Mortgage File for Delay
Delivery Mortgage Loans nor the failure to repurchase or substitute in lieu
thereof; or

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

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

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



                                       122

<PAGE>



         (vi) the Master Servicer shall fail to reimburse in full the Trustee
not later than 6:00 P.M., New York time on the Business Day following the
related Distribution Date Date for any Advance made by the Trustee pursuant to
Section 4.01(b) together with accrued and unpaid interest.

         If an Event of Default shall occur, then, and in each and every such
case, so long as such Event of Default shall not have been remedied, the Trustee
shall, but only at the direction of the Holders of Certificates evidencing not
less than 25% of the Voting Rights evidenced by the Certificates, by notice in
writing to the Master Servicer (with a copy to each Rating Agency), terminate
all of the rights and obligations of the Master Servicer under this Agreement
and in and to the Mortgage Loans and the proceeds thereof, other than its rights
as a Certificateholder hereunder. On or after the receipt by the Master Servicer
of such written notice, all authority and power of the Master Servicer
hereunder, whether with respect to the Mortgage Loans or otherwise, shall pass
to and be vested in the Trustee. The Trustee shall thereupon make any Advance
described in Section 4.01 hereof subject to Section 3.04 hereof. The Trustee 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
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. Unless expressly provided in such written
notice, no such termination shall affect any obligation of the Master Servicer
to pay amounts owed pursuant to Article VIII. The Master Servicer agrees to
cooperate with the Trustee in effecting the termination of the Master Servicer's
responsibilities and rights hereunder, including, without limitation, the
transfer to the Trustee of all cash amounts which shall at the time be credited
to the Certificate Account, or thereafter be received with respect to the
Mortgage Loans. The Trustee shall promptly notify the Rating Agencies of the
occurrence of an Event of Default.

         Notwithstanding any termination of the activities of a Master Servicer
hereunder, such Master Servicer shall be entitled to receive, out of any late
collection of a Scheduled Payment on a Mortgage Loan that was due prior to the
notice terminating such Master Servicer's rights and obligations as Master
Servicer hereunder and received after such notice, that portion thereof to which
such Master Servicer would have been entitled pursuant to Sections 3.08(a)(i)
through (viii), and any other amounts payable to such Master Servicer hereunder
the entitlement to which arose prior to the termination of its activities
hereunder.

         Section 7.02 Trustee to Act; Appointment of Successor.

         On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01 hereof, the Trustee shall, to the extent
provided in Section 3.04, be the successor 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 and applicable law including the obligation to make advances
pursuant to Section 4.01. As compensation therefor, the Trustee shall be
entitled to all fees, costs and expenses relating to the Mortgage Loans that the
Master Servicer


                                       123

<PAGE>



would have been entitled to if the Master Servicer had continued to act
hereunder. Notwithstanding the foregoing, if the Trustee has become the
successor to the Master Servicer in accordance with Section 7.01 hereof, the
Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited
by applicable law from making Advances pursuant to Section 4.01 hereof or if it
is otherwise unable to so act, appoint, or petition a court of competent
jurisdiction to appoint, any established mortgage loan servicing institution the
appointment of which does not adversely affect the then current rating of the
Certificates by each Rating Agency 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. Any successor Master Servicer
shall be an institution that is a Fannie Mae and Freddie Mac approved
seller/servicer in good standing, that has been approved by the Mortgage
Insurer, that has a net worth of at least $15,000,000, and that is willing to
service the Mortgage Loans and executes and delivers to the Depositor and the
Trustee an agreement accepting such delegation and assignment, that contains an
assumption by such Person of the rights, powers, duties, responsibilities,
obligations and liabilities of the Master Servicer (other than liabilities of
the Master Servicer under Section 6.03 hereof incurred prior to termination of
the Master Servicer under Section 7.01), with like effect as if originally named
as a party to this Agreement; and provided further that each Rating Agency
acknowledges that its rating of the Certificates in effect immediately prior to
such assignment and delegation will not be qualified or reduced as a result of
such assignment and delegation. No appointment of a successor to the Master
Servicer hereunder shall be effective until the Trustee shall have consented
thereto, and written notice of such proposed appointment shall have been
provided by the Trustee to each Certificateholder. The Trustee shall not resign
as servicer until a successor servicer has been appointed and has accepted such
appointment. Pending appointment of a successor to the Master Servicer
hereunder, the Trustee, unless the Trustee is prohibited by law from so acting,
shall, subject to Section 3.04 hereof, act in such capacity as hereinabove
provided. In connection with such appointment and assumption, the Trustee may
make such arrangements for the compensation of such successor out of payments on
Mortgage Loans as it and such successor shall agree; provided that no such
compensation shall be in excess of that permitted the Master Servicer hereunder.
The Trustee and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession. Neither the
Trustee nor any other successor servicer shall be deemed to be in default
hereunder by reason of any failure to make, or any delay in making, any
distribution hereunder or any portion thereof or any failure to perform, or any
delay in performing, any duties or responsibilities hereunder, in either case
caused by the failure of the Master Servicer to deliver or provide, or any delay
in delivering or providing, any cash, information, documents or records to it.

         Any successor to the Master Servicer as servicer shall give notice to
the Mortgagors of such change of servicer and shall, during the term of its
service as servicer maintain in force the policy or policies that the Master
Servicer is required to maintain pursuant to Section 6.05.

         In connection with the termination or resignation of the Master
Servicer hereunder, either (i) the successor Master Servicer, including the
Trustee if the Trustee is acting as successor Master Servicer, shall represent

deliver such other notices, documents and other instruments as may be necessary
or desirable to effect a transfer of such Mortgage Loan or servicing of such

                                  ARTICLE VIII

                    CONCERNING THE TRUSTEE AND THE CO-TRUSTEE

         Section 8.01 Duties of Trustee.

         The Trustee, prior to the occurrence of an Event of Default and after
the curing of all Events of Default that may have occurred, shall undertake to
perform such duties and only such duties as are specifically set forth in this
Agreement. In case an Event of Default has occurred and remains uncured, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement, and use the same degree of care and skill in their exercise as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

         The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee (or the Co-Trustee, to the extent provided in this Agreement) that are
specifically required to be furnished pursuant to any provision of this
Agreement shall examine them to determine whether they conform to the
requirements of this Agreement, to the extent provided in this Agreement. If any
such instrument is found not to conform to the requirements of this Agreement in
a material manner, the Trustee shall take action as it deems appropriate to have
the instrument corrected.

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

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

         (ii) the Trustee shall not be liable, individually or as Trustee, for
an error of judgment made in good faith by a Responsible Officer or Responsible
Officers of the Trustee, unless the Trustee was grossly negligent or acted in
bad faith or with willful misfeasance;

         (iii) the Trustee shall not be liable, individually or as Trustee, with
respect to any action taken, suffered or omitted to be taken by it in good faith
in accordance with the direction of Holders


                                       126

of each Class of Certificates evidencing not less than 25% of the Voting Rights
of such Class relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee under this Agreement; and

         (vi) without in any way limiting the provisions of this Section 8.01 or
Section 8.02 hereof, the Trustee shall be entitled to rely conclusively on the
information delivered to it by the Master Servicer in a Trustee Advance Notice
in determining whether or not it is required to make an Advance under Section
4.01(b), shall have no responsibility to ascertain or confirm any information
contained in any Trustee Advance Notice, and shall have no obligation to make
any Advance under Section 4.01(b) in the absence of a Trustee Advance Notice.

         (a)      Except as otherwise provided in Section 8.01:

         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, appraisal, bond or other paper or document believed by
         it to be genuine and to have been signed or presented by the proper
         party or parties;

                  (ii) the Trustee may consult with counsel 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 not be liable, individually or as
         Trustee, 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;

                  (iv) prior to the occurrence of an Event of Default hereunder
         and after the curing of all Events of Default that may have occurred,

         or matters stated in any resolution, certificate, statement,
         instrument, opinion, report, notice, request, consent, order, approval,
         bond or other paper or document, unless requested in writing so to do
         by Holders of each Class of Certificates evidencing not less than 25%
         of the Voting Rights of such Class;

                  (v) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents, accountants or attorneys;

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


                                       127

<PAGE>




                  (vii) the Trustee shall not be liable, individually or as
         Trustee, for any loss on any investment of funds pursuant to this
         Agreement (other than in its commercial capacity as issuer of the
         investment security);

                  (viii) the Trustee shall not be deemed to have knowledge of an
         Event of Default until a Responsible Officer of the Trustee shall have
         received written notice thereof; and

                  (ix) the Trustee shall be under no obligation to exercise any
         of the trusts or powers vested in it by this Agreement or to make any
         investigation of matters arising hereunder or to institute, conduct or
         defend any litigation hereunder or in relation hereto at the request,
         order or direction of any of the Certificateholders, pursuant to the
         provisions of this Agreement, unless such Certificateholders shall have
         offered to the Trustee reasonable security or indemnity against the
         costs, expenses and liabilities that may be incurred therein or
         thereby.

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

         Section 8.03 Trustee Not Liable for Mortgage Loans.

         The recitals contained herein shall be taken as the statements of the
Depositor or the Master Servicer, as the case may be, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Agreement or of any Mortgage Loan or related
document or of MERS or the MERS(R) System other than with respect to the
Trustee's execution and authentication of the Certificates. The Trustee shall
not be accountable for the use or application by the Depositor or the Master
Servicer of any funds paid to the Depositor or the Master Servicer in respect of

         Section 8.04 Trustee May Own Certificates.

         Section 8.05 Master Servicer to Pay Trustee's Fees and Expenses.

         The Master Servicer covenants and agrees to pay or reimburse the
Trustee, upon its request, for all reasonable expenses, disbursements and
advances incurred or made by the Trustee on behalf of the Trust Fund in
accordance with any of the provisions of this Agreement (including, without
limitation: (A) the reasonable compensation and the expenses and disbursements
of its counsel, but only for representation of the Trustee acting in its
capacity as Trustee hereunder and (B) to the extent that the Trustee must engage
persons not regularly in its employ to perform acts or services on behalf of the
Trust Fund, which acts or services are not in the ordinary course of the duties
of a trustee, paying agent or certificate registrar, in the absence of a breach
or default by any party hereto, the reasonable compensation, expenses and
disbursements of such persons, except any such expense, disbursement or advance
as may arise from its negligence, bad faith or willful misconduct). The Trustee
and any director, officer, employee or agent of the Trustee shall be indemnified
by the Master Servicer and held harmless against any loss, liability or expense
(i) incurred in connection with any legal action relating to this Agreement or
the Certificates, or in connection with the performance of any of the Trustee's
duties hereunder, other than any loss, liability or expense incurred by reason
of willful misfeasance, bad faith or negligence in the performance of any of the
Trustee's duties hereunder or by reason of reckless disregard of the Trustee's
obligations and duties hereunder and (ii) resulting from any error in any tax or
information return prepared by the Master Servicer. Such indemnity shall survive
the termination of this Agreement or the resignation or removal of the Trustee
hereunder.

         Section 8.06 Eligibility Requirements for Trustee.

         The Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on the
Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.07 hereof. The corporation or
national banking association serving as Trustee may have normal banking and
trust relationships with the Depositor, the Seller and the Master Servicer and
their respective affiliates; provided that such corporation cannot be an
affiliate of the Master Servicer other than the Trustee in its role as successor
to the Master Servicer.

         Section 8.07 Resignation and Removal of Trustee.

         The Trustee may at any time resign and be discharged from the trusts
hereby created by (1) giving written notice of resignation to the Depositor and
the Master Servicer and by mailing notice of resignation by first class mail,
postage prepaid, to the Certificateholders at their addresses appearing on the
Certificate Register and each Rating Agency, not less than 60 days before the
date specified in such notice when, subject to Section 8.08, such resignation is
to take effect, and (2) acceptance of appointment by a successor trustee in
accordance with Section 8.08 and meeting the qualifications set forth in Section
8.06. If no successor trustee shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice or resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee.

         If at any time (i) the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 hereof and shall fail to resign after
written request thereto by the Depositor, (ii) the Trustee shall become
incapable of acting, or shall be adjudged as bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or
(iii)(A) a tax is imposed with respect to the Trust Fund by any state in which
the Trustee or the Trust Fund is located, (B) the imposition of such tax would
be avoided by the appointment of a different trustee and (C) the Trustee fails
to indemnify the Trust Fund against such tax, then the Depositor or the Master
Servicer may remove the Trustee and appoint a successor trustee by written
instrument, in triplicate, one copy of which instrument shall be delivered to
the Trustee, one copy of which shall be delivered to the Master Servicer and one
copy of which shall be delivered to the successor trustee.

         The Holders evidencing at least 51% of the Voting Rights of each Class
of Certificates may at any time remove the Trustee and appoint a successor
trustee by written instrument or instruments, in triplicate, signed by such
Holders or their attorneys-in-fact duly authorized, one complete set of which
instruments shall be delivered by the successor Trustee to the Master Servicer
one complete set to the Trustee so removed and one complete set to the successor
so appointed. Notice of any removal of the Trustee shall be given to each Rating
Agency by the Successor Trustee.

         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
become effective upon acceptance of appointment by the successor trustee as
provided in Section 8.08 hereof.

         Section 8.08 Successor Trustee.

         Any successor trustee appointed as provided in Section 8.07 hereof
shall execute, acknowledge and deliver to the Depositor, its predecessor trustee
and the Master Servicer 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


                                       130

<PAGE>



or conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally
named as trustee herein.

         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 hereof and its appointment
shall not adversely affect the then current rating of the Certificates.

         Upon acceptance of appointment by a successor trustee as provided in
this Section 8.08, the Depositor shall mail notice of the succession of such
trustee hereunder to all Holders of Certificates. If the Depositor fails to mail
such notice within ten days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Depositor.

         Section 8.09 Merger or Consolidation of Trustee.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to substantially all of the corporate trust business of
the Trustee, shall be the successor of the Trustee hereunder, provided that such
corporation shall be eligible under the provisions of Section 8.06 hereof
without the execution or filing of any paper or further act on the part of any
of the parties hereto, anything herein to the contrary notwithstanding.

         Section 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 Fund or property securing any Mortgage Note may at the
time be located, the Master Servicer and the Trustee acting jointly shall have
the power and shall execute and deliver all instruments to appoint one or more
Persons approved by the Trustee to act as co-trustee or co-trustees jointly with
the Trustee, or separate trustee or separate trustees, of all or any part of the
Trust Fund, and to vest in such Person or Persons, in such capacity and for the
benefit of the Certificateholders, such title to the Trust Fund or any part
thereof, whichever is applicable, 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. If the Master
Servicer shall not have joined in such appointment within 15 days after the
receipt by it of a request to do so, or in the case an Event of Default shall
have occurred and be continuing, the Trustee alone shall have the power to make
such appointment. No co-trustee or separate trustee hereunder shall be required
to meet the terms of eligibility as a successor trustee under Section 8.06 and
no notice to Certificateholders of the appointment of any co-trustee or separate
trustee shall be required under Section 8.08.

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


                                       131

<PAGE>



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

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

         (iii) The Trustee may at any time accept the resignation of or remove
any separate trustee or co-trustee.

         Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article 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
Master Servicer and the Depositor.

         Any separate trustee or co-trustee may, at any time, constitute the
Trustee its agent or attorney-in-fact, with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. 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 Tax Matters.

         It is intended that the Trust Fund shall constitute, and that the
affairs of the Trust Fund shall be conducted so that each of REMIC I and REMIC
II will qualify as, a "real estate mortgage investment conduit" as defined in
and in accordance with the REMIC Provisions. In furtherance of such intention,
the Trustee covenants and agrees that it shall act as agent (and the Trustee is
hereby appointed to act as agent) on behalf of the Trust Fund and that in such
capacity it shall: (a) prepare and file, or cause to be prepared and filed, in a
timely manner, a U.S. Real Estate Mortgage


                                       132

authorities income tax or information returns for each taxable year with respect
to each REMIC created hereunder containing such information and at the times and
in the manner as may be required by the Code or state or local tax laws,
regulations, or rules, and furnish or cause to be furnished to
Certificateholders the schedules, statements or information at such times and in
such manner as may be required thereby; (b) within thirty days of the Closing
Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms
8811 or as otherwise may be required by the Code, the name, title, address, and

for tax information relating thereto, together with such additional information
as may be required by such Form, and update such information at the time or
times in the manner required by the Code for the Trust Fund; (c) make or cause
to be made elections, on behalf of each REMIC created hereunder to be treated as
a REMIC on the federal tax return of each such REMIC for its first taxable year
(and, if necessary, under applicable state law); (d) prepare and forward, or
cause to be prepared and forwarded, to the Certificateholders and to the
Internal Revenue Service and, if necessary, state tax authorities, all
information returns and reports as and when required to be provided to them in
accordance with the REMIC Provisions, including without limitation, the
calculation of any original issue discount using the Prepayment Assumption; (e)
provide information necessary for the computation of tax imposed on the transfer
of a Class A-R Certificate to a Person that is not a Permitted Transferee, or an
agent (including a broker, nominee or other middleman) of a Non-Permitted
Transferee, or a pass-through entity in which a Non-Permitted Transferee is the
record holder of an interest (the reasonable cost of computing and furnishing
such information may be charged to the Person liable for such tax); (f) to the
extent that they are under its control conduct the affairs of the Trust Fund at
all times that any Certificates are outstanding so as to maintain the status of
each REMIC created hereunder as a REMIC under the REMIC Provisions; (g) not
knowingly or intentionally take any action or omit to take any action that would
cause the termination of the REMIC status of any REMIC created hereunder; (h)
pay, from the sources specified in the last paragraph of this Section 8.11, the
amount of any federal, state and local taxes, including prohibited transaction
taxes as described below, imposed on any REMIC created hereunder prior to the
termination of the Trust Fund when and as the same shall be due and payable (but
such obligation shall not prevent the Trustee or any other appropriate Person
from contesting any such tax in appropriate proceedings and shall not prevent
the Trustee from withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings); (i) sign or cause to be signed federal, state
or local income tax or information returns; (j) maintain records relating to
each REMIC created hereunder, including but not limited to the income, expenses,
assets and liabilities of each such REMIC, and the fair market value and
adjusted basis of the Trust Fund property determined at such intervals as may be
required by the Code, as may be necessary to prepare the foregoing returns,
schedules, statements or information; and (k) as and when necessary and
appropriate, represent the Trust Fund in any administrative or judicial
proceedings relating to an examination or audit by any governmental taxing
authority, request an administrative adjustment as to any taxable year of any
REMIC created hereunder, enter into settlement agreements with any governmental
taxing agency, extend any statute of limitations


                                       133

<PAGE>



relating to any tax item of the Trust Fund, and otherwise act on behalf of any
REMIC created hereunder in relation to any tax matter involving any such REMIC.

         In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within 10 days after the Closing Date all information or data that the Trustee
requests in writing and determines to be relevant for tax purposes to the
valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows of
the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide
to the Trustee promptly upon written request therefor, any such additional
information or data that the Trustee may, from time to time, request in order to
enable the Trustee to perform its duties as set forth herein. The Depositor
hereby indemnifies the Trustee for any losses, liabilities, damages, claims or
expenses of the Trustee arising from any errors, omissions or miscalculations of
the Trustee that result from any failure of the Depositor to provide, or to
cause to be provided, accurate information or data to the Trustee on a timely
basis.

         In the event that any tax is imposed on "prohibited transactions" of
the Trust Fund as defined in Section 860F(a)(2) of the Code, on the "net income
from foreclosure property" of the Trust Fund as defined in Section 860G(c) of
the Code, on any contribution to the Trust Fund after the startup day pursuant
to Section 860G(d) of the Code, or any other tax is imposed, including, without
limitation, any federal, state or local tax or minimum tax imposed upon the
Trust Fund pursuant to Sections 23153 and 24872 of the California Revenue and
Taxation Code if not paid as otherwise provided for herein, such tax shall be
paid by (i) the Trustee, if any such other tax arises out of or results from a
breach by the Trustee of any of its obligations under this Agreement, (ii) (x)
the Master Servicer, in the case of any such minimum tax, and (y) any party
hereto (other than the Trustee) to the extent any such other tax arises out of
or results from a breach by such other party of any of its obligations under
this Agreement or (iii) in all other cases, or in the event that any liable
party here fails to honor its obligations under the preceding clauses (i) or
(ii), any such tax will be paid first with amounts otherwise to be distributed
to the Class A-R Certificateholders , and second with amounts otherwise to be
distributed to all other Certificateholders in the following order of priority:
first, to the Class B Certificates (pro rata), second, to the Class M-6
Certificates (pro rata), third, to the Class M-5 Certificates (pro rata),
fourth, to the Class M-4 Certificates (pro rata), fifth, to the Class M-3
Certificates (pro rata), sixth, to the Class M-2 Certificates (pro rata),
seventh, to the Class M-1 Certificates (pro rata), and eighth, to the Class 1-A,
Class 2-A-1 and 2-A-2 Certificates (pro rata). Notwithstanding anything to the
contrary contained herein, to the extent that such tax is payable by the Class
A-R Certificates, the Trustee is hereby authorized to retain on any Distribution
Date, from the Holders of the Class A-R Certificates (and, if necessary, second,
from the Holders of the all other Certificates in the priority specified in the
preceding sentence), funds otherwise distributable to such Holders in an amount
sufficient to pay such tax. The Trustee agrees to promptly notify in writing the
party liable for any such tax of the amount thereof and the due date for the
payment thereof.

         The Trustee shall treat the rights of the Class 1-A, Class 2-A-1, Class
2-A-2, Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6 and
Class B Certificateholders to receive


                                       134

payments from the Carryover Reserve Fund as rights in three interest rate cap
contracts written by the Cap Contract Counterparty with respect to the Net Rate
Carryover funded by the Cap Contracts and Excess Cashflow, in favor of the
Certificateholders (other than the Holders of the Class A-R, Class C and Class P
Certificates). Thus, each Certificate (other than the Class A-R, Class C and
Class P Certificates) shall be treated as representing ownership of not only
REMIC II Regular Interests, but also ownership of an interest in three interest
rate cap contracts. For purposes of determining the issue price of the REMIC II
Regular Interests, the Trustee shall assume that the Class 1-A Cap Contract,
Class 2-A Cap Contract and Subordinated Cap Contract have values of $220,000,
$760,000 and $672,000, respectively .

         Section 8.12 Co-Trustee.

         (a) The Co-Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Co-Trustee that are specifically required to be furnished pursuant to any
provision of this Agreement shall examine them to determine whether they conform
to the requirements of this Agreement, to the extent required by this Agreement.
If any such instrument is found not to conform to the requirements of this
Agreement in a material manner, the Co-Trustee shall take action as it deems
appropriate to have the instrument corrected. In addition, the Co-Trustee shall
act as the insured under the Mortgage Insurance Policy and hereby directs the
Master Servicer, on behalf of the Co-Trustee, to take all actions appropriate or
required of the Co-Trustee under the Mortgage Insurance Policy, other than the
payment of the Mortgage Insurance Premium and obtaining the approval of the
Mortgage Insurer with respect to the appointment of a successor servicer.

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

                  (i) the duties and obligations of the Co-Trustee shall be
         determined solely by the express provisions of this Agreement with the
         exception of Section 8.10, the Co-Trustee shall not be liable,
         individually or as Co-Trustee, 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 Co-Trustee and the Co-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
         Co-Trustee and conforming to the requirements of this Agreement that it
         reasonably believed in good faith to be genuine and to have been duly
         executed by the proper authorities respecting any matters arising
         hereunder; and

                  (ii) the Co-Trustee shall not be liable, individually or as
         Co-Trustee, for an error of judgment made in good faith by a
         Responsible Officer or Responsible Officers of the


                                       135

<PAGE>



         Trustee, unless the Co-Trustee was grossly negligent or acted in bad
         faith or with willful misfeasance.

         (c)      Except as otherwise provided in paragraph (b) above:

                  (i) the Co-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 believed by
         it to be genuine and to have been signed or presented by the proper
         party or parties;

                  (ii) the Co-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 Co-Trustee shall not be liable, individually or as
         Co-Trustee, 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;

                  (iv) the Co-Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, approval, bond or other paper or document;

                  (v) the Co-Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents, accountants or attorneys; and

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

         (d) The recitals contained herein shall be taken as the statements of
the Depositor or the Master Servicer, as the case may be, and the Co-Trustee
assumes no responsibility for their correctness. The Co-Trustee makes no
representations as to the validity or sufficiency of this Agreement or of any
Mortgage Loan or related document or of MERS or the MERS(R) System other than
with respect to the Co-Trustee's execution and authentication of the
Certificates. The Co-Trustee shall not be accountable for the use or application
by the Depositor or the Master Servicer of any funds paid to the Depositor or
the Master Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Certificate Account by the Depositor or the Master Servicer.

         (e) The Co-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 the Co-Trustee.



                                       136

         (f) The Master Servicer covenants and agrees (i) to pay to the
Co-Trustee from time to time, and the Co-Trustee shall be entitled to, such
compensation as shall be agreed in writing by the Master Servicer and the
Co-Trustee (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 it
in the execution of the trusts hereby created and in the exercise and
performance of any of the powers and duties hereunder of the Co-Trustee and (ii)
to pay or reimburse the Co-Trustee, upon its request, for all reasonable
expenses, disbursements and advances incurred or made by the Co-Trustee on
behalf of the Trust Fund in accordance with any of the provisions of this
Agreement (including, without limitation: (A) the reasonable compensation and
the expenses and disbursements of its counsel, but only for representation of
the Co-Trustee acting in its capacity as Co-Trustee hereunder and (B) to the
extent that the Co-Trustee must engage persons not regularly in its employ to
perform acts or services on behalf of the Trust Fund, which acts or services are
not in the ordinary course of the duties of a trustee, paying agent or
certificate registrar, in the absence of a breach or default by any party
hereto, the reasonable compensation, expenses and disbursements of such persons,
except any such expense, disbursement or advance as may arise from its
negligence, bad faith or willful misconduct). The Co-Trustee and any director,
officer, employee or agent of the Co-Trustee shall be indemnified by the Master
Servicer and held harmless against any loss, liability or expense (i) incurred
in connection with any legal action relating to this Agreement or the
Certificates, or in connection with the performance of any of the Co-Trustee's
duties hereunder, other than any loss, liability or expense incurred by reason
of willful misfeasance, bad faith or negligence in the performance of any of the
Co-Trustee's duties hereunder or by reason of reckless disregard of the
Co-Trustee's obligations and duties hereunder and (ii) resulting from any error
in any tax or information return prepared by the Master Servicer. Such indemnity
shall survive the termination of this Agreement or the resignation or removal of
the Co-Trustee hereunder.

         (g) The Co-Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on the
Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.12 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Co-Trustee shall cease to be eligible in accordance with
the provisions of this Section 8.12, the Co-Trustee shall resign immediately in
the manner and with the effect specified in paragraph (h) below. The corporation
or national banking association serving as Co-Trustee may have normal banking
and trust relationships with the Depositor, the Seller and the Master Servicer
and their respective affiliates; provided that such corporation cannot be an
affiliate of the Master Servicer other than the Trustee in its role as successor
to the Master Servicer.



                                       137

<PAGE>



         (h) The Co-Trustee may at any time resign and be discharged from the
trusts hereby created by giving 30 days prior written notice of resignation to
the Trustee, the Depositor and the Master Servicer. Upon such resignation the
Trustee (x) may appoint a successor Co-Trustee meeting the requirements in
paragraph (g) above and acceptable to the Master Servicer (in its sole
discretion), so long as such Co-Trustee executes and delivers to the other
parties hereto an instrument agreeing to be bound by the provisions of this
Agreement or (y) may if permitted by the Master Servicer (in its sole
discretion) assume the rights and duties of the resigning Co-Trustee so long as
the Trustee executes and delivers an instrument to that effect.

                                   TERMINATION

         Section 9.01 Termination upon Liquidation or Repurchase of all Mortgage
                      Loans.

         Subject to Section 9.03, the Trust Fund shall terminate and the
obligations and responsibilities of the Depositor, the Master Servicer, the
Seller and the Trustee created hereby shall terminate upon the earlier of (a)
the purchase by the Master Servicer of all of the Mortgage Loans (and REO
Properties) remaining in the Trust Fund at the price equal to the sum of (i)
100% of the Stated Principal Balance of each Mortgage Loan in the Trust Fund
(other than in respect of REO Property), (ii) accrued interest thereon at the
applicable Mortgage Rate (or, if such repurchase is effected by the Master
Servicer, at the applicable Net Mortgage Rate), (iii) the appraised value of any
REO Property in the Trust Fund (up to the Stated Principal Balance of the
related Mortgage Loan), such appraisal to be conducted by an appraiser mutually
agreed upon by the Master Servicer and the Trustee and (iv) any unreimbursed
Servicing Advances, and the principal portion of any unreimbursed Advances, made
on the Mortgage Loans prior to the exercise of such repurchase and (b) the later
of (i) the maturity or other liquidation (or any Advance with respect thereto)
of the last Mortgage Loan remaining in the Trust Fund and the disposition of all
REO Property and (ii) the distribution to related Certificateholders of all
amounts required to be distributed to them pursuant to this Agreement, as
applicable. In no event shall the trusts created hereby continue beyond the
earlier of (i) 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 and (ii) the Latest
Possible Maturity Date.

         The right to purchase all Mortgage Loans and REO Properties by the
Master Servicer (the party exercising such purchase option, the "Terminator")
pursuant to clause (a) above shall be conditioned upon the Stated Principal
Balance of the Mortgage Loans, at the time of any such repurchase, aggregating
ten percent (10%) or less of the Stated Principal Balance of the Mortgage Loans
as of the Cut-off Date.

         Section 9.02 Final Distribution on the Certificates.

         If on any Determination Date, (i) the Master Servicer determines that
there are no Outstanding Mortgage Loans and no other funds or assets in the
Trust Fund other than the funds in the Certificate Account, the Master Servicer
shall direct the Trustee to send a final distribution notice promptly to each
Certificateholder or (ii) the Trustee determines that a Class of Certificates
shall be retired after a final distribution on such Class, the Trustee shall
notify the related Certificateholders within five (5) Business Days after such
Determination Date that the final distribution in retirement of such Class of
Certificates is scheduled to be made on the immediately following Distribution
Date. Any final distribution made pursuant to the immediately preceding sentence
will be made only upon presentation and surrender of the related Certificates at
the Corporate Trust Office of the Trustee. If the Master Servicer elects to
terminate the Trust Fund pursuant to clause (a) of Section 9.01, at least 20
days prior to the date notice is to be mailed to the Certificateholders, such
electing party shall notify the Depositor and the Trustee of the date such
electing party intends to terminate the Trust Fund and of the applicable
repurchase price of the related Mortgage Loans and REO Properties.

         Notice of any termination of the Trust Fund, specifying the
Distribution Date on which related Certificateholders may surrender their
Certificates for payment of the final distribution and cancellation, shall be
given promptly by the Trustee by letter to related Certificateholders mailed not
earlier than the 10th day and no later than the 15th day of the month
immediately preceding the month of such final distribution. Any such notice
shall specify (a) the Distribution Date upon which final distribution on related
Certificates will be made upon presentation and surrender of such Certificates
at the office therein designated, (b) the amount of such final distribution, (c)
the location of the office or agency at which such presentation and surrender
must be made, and (d) that the Record Date otherwise applicable to such
Distribution Date is not applicable, distributions being made only upon
presentation and surrender of such Certificates at the office therein specified.
The Master Servicer will give such notice to each Rating Agency at the time such
notice is given to the affected Certificateholders.

         In the event such notice is given, the Master Servicer shall cause all
funds in the Certificate Account to be remitted to the Trustee for deposit in
the Distribution Account on the Business Day prior to the applicable
Distribution Date in an amount equal to the final distribution in respect of the
related Certificates. Upon such final deposit and the receipt by the Trustee of
a Request for Release therefor, the Co-Trustee shall promptly release to the
Master Servicer the Mortgage Files for the related Mortgage Loans.

         Upon presentation and surrender of the related Certificates, the
Trustee shall cause to be distributed to Certificateholders of each affected
Class the amounts allocable to such Certificates held in the Distribution
Account (and, if applicable, the Carryover Reserve Fund) in the order and
priority set forth in Section 4.04 hereof on the final Distribution Date and in
proportion to their respective Percentage Interests.



                                       139

<PAGE>



         In the event that any affected Certificateholders shall not surrender
related Certificates for cancellation within six months after the date specified
in the above mentioned written notice, the Trustee shall give a second written
notice to the remaining Certificateholders to surrender their related
Certificates for cancellation and receive the final distribution with respect
thereto. If within six months after the second notice all the applicable
Certificates shall not have been surrendered for cancellation, the Trustee may
take appropriate steps, or may appoint an agent to take appropriate steps, to
contact the remaining Certificateholders concerning surrender of their
Certificates, and the cost thereof shall be paid out of the funds and other
assets that remain a part of the Trust Fund. If within one year after the second
notice all related Certificates shall not have been surrendered for
cancellation, the Class A-R Certificates shall be entitled to all unclaimed
funds and other assets that remain subject hereto.

         Section 9.03 Additional Termination Requirements.

         (a) In the event the Master Servicer exercises its purchase option on
the Mortgage Loans, the Trust Fund shall be terminated in accordance with the
following additional requirements, unless the Trustee has been supplied with an
Opinion of Counsel, at the expense of the Master Servicer, to the effect that
the failure of the Trust Fund to comply with the requirements of this Section
9.03 will not (i) result in the imposition of taxes on "prohibited transactions"
of a REMIC, or (ii) cause any REMIC created hereunder to fail to qualify as a
REMIC at any time that any Certificates are outstanding:

         (1) The Master Servicer shall establish a 90 day liquidation period and
notify the Trustee thereof, which shall in turn specify the first day of such
period in a statement attached to the Trust Fund's final Tax Return pursuant to
Treasury Regulation Section 1.860F 1. The Master Servicer shall prepare a plan
of complete liquidation and shall otherwise satisfy all the requirements of a
qualified liquidation under Section 860F of the Code and any regulations
thereunder, as evidenced by an Opinion of Counsel obtained at the expense of the
Master Servicer;

         (2) During such 90 day liquidation period, and at or prior to the time
of making the final payment on the Certificates, the Master Servicer as agent of
the Trustee shall sell all of the assets of the Trust Fund for cash; and

         (3) At the time of the making of the final payment on the Certificates,
the Trustee shall distribute or credit, or cause to be distributed or credited,
to the Class A-R Certificateholders all cash on hand (other than cash retained
to meet claims) related to such Class of Certificates, and the Trust Fund shall
terminate at that time.

         (b) By their acceptance of the Certificates, the Holders thereof hereby
authorize the Master Servicer to specify the 90 day liquidation period for the
Trust Fund, which authorization shall be binding upon all successor
Certificateholders.



                                       140

<PAGE>



         (c) The Trustee as agent for each REMIC created hereunder hereby agrees
to adopt and sign such a plan of complete liquidation upon the written request
of the Master Servicer, and, together with the holders of the Class A-R
Certificates, agree to take such other action in connection therewith as may be
reasonably requested by the Master Servicer.

                            MISCELLANEOUS PROVISIONS

         Section 10.01 Amendment.

         This Agreement may be amended from time to time by the Depositor, the
Master Servicer, the Seller and the Trustee, without the consent of any of the
Certificateholders to cure any ambiguity, to correct or supplement any
provisions herein, to make such other provisions with respect to matters or
questions arising under this Agreement, as shall not be inconsistent with any
other provisions herein or to give effect to the expectations of the investors
if such action shall not, as evidenced by an Opinion of Counsel, adversely
affect in any material respect the interests of any Certificateholder; provided
that any such amendment shall be deemed not to adversely affect in any material
respect the interests of the Certificateholders and no such Opinion of Counsel
shall be required if the Person requesting such amendment obtains a letter from
each Rating Agency stating that such amendment would not result in the
downgrading or withdrawal of the respective ratings then assigned to the
Certificates, it being understood and agreed that any such letter in and of
itself will not represent a determination as to the materiality of any such
amendment and will represent a determination only as to the credit issues
affecting any such rating. Notwithstanding the foregoing, no amendment that
significantly changes the permitted activities of the trust created by this
Agreement may be made without the consent of Certificateholders representing not
less than 51% of the Voting Rights of each Class of Certificates affected by
such amendment.

         The Trustee, the Depositor, the Master Servicer and the Seller may also
at any time and from time to time amend this Agreement, without the consent of
the Certificateholders, to modify, eliminate or add to any of its provisions to
such extent as shall be necessary or appropriate to maintain the qualification
of the Trust Fund as a REMIC under the Code or to avoid or minimize the risk of
the imposition of any tax on the Trust Fund pursuant to the Code that would be a
claim against the Trust Fund at any time prior to the final redemption of the
Certificates, provided that the Trustee have been provided an Opinion of
Counsel, which opinion shall be an expense of the party requesting such opinion
but in any case shall not be an expense of the Trustee, to the effect that such
action is necessary or appropriate to maintain such qualification or to avoid or
minimize the risk of the imposition of such a tax.

         This Agreement may also be amended from time to time by the Depositor,
the Master Servicer, the Seller and the Trustee and the Holders of each Class of
Certificates adversely affected thereby evidencing not less than a majority
Percentage Interest of the Voting Rights of such Class 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 that no such amendment pursuant to this paragraph shall
(i) reduce in any manner the amount of, or delay the timing of, payments
required to be distributed on any Certificate without the consent of the Holder
of such Certificate, (ii) adversely affect in any material respect the interests
of the Holders of any Class of Certificates in a manner other than as described
in (i), without the


                                       142

<PAGE>



consent of the Holders of Certificates of such Class evidencing 66% or more of
the Voting Rights of such Class, or (iii) reduce the aforesaid percentages of
Certificates the Holders of which are required to consent to any such amendment
without the consent of the Holders of all such Certificates then outstanding.

         Notwithstanding any contrary provision of this Agreement, the Trustee
shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel, which opinion shall be an expense of the party
requesting such amendment but in any case shall not be an expense of the
Trustee, to the effect that such amendment will not cause the imposition of any
tax on the Trust Fund or the Certificateholders or cause the Trust Fund to fail
to qualify as a REMIC at any time that any Certificates are outstanding.

         Promptly after the execution of any amendment to this Agreement
requiring the consent of Certificateholders, the Trustee shall furnish written
notification of the substance of such amendment to each Certificateholder and
each Rating Agency.

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

         Nothing in this Agreement shall require the Trustee to enter into an
amendment without receiving an Opinion of Counsel, satisfactory to the Trustee
that (i) such amendment is permitted and is not prohibited by this Agreement and
that all requirements for amending this Agreement have been complied with; and
(ii) either (A) the amendment does not adversely affect in any material respect
the interests of any Certificateholder or (B) the conclusion set forth in the
immediately preceding clause (A) is not required to be reached pursuant to this
Section 10.01.

         Section 10.02 Recordation of Agreement; Counterparts.

         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 its expense.

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

         Section 10.03 Governing Law.

         THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND
TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS WITHOUT REGARD TO THE CONFLICTS OF LAWS PRINCIPLES
THEREOF.

         Section 10.04 Intention of Parties.

         It is the express intent of the parties hereto that the conveyance of
the Mortgage Notes, Mortgages, assignments of Mortgages, title insurance
policies and any modifications, extensions and/or assumption agreements and
private mortgage insurance policies relating to the Mortgage Loans by the
Depositor to the Trustee be, and be construed as, an absolute sale thereof to
the Trustee. It is, further, not the intention of the parties that such
conveyance be deemed a pledge thereof by the Depositor to the Trustee. However,
in the event that, notwithstanding the intent of the parties, such assets are
held to be the property of the Depositor, or if for any other reason this
Agreement is held or deemed to create a security interest in such assets, then
(i) this Agreement shall be deemed to be a security agreement (within the
meaning of the Uniform Commercial Code of the State of New York) with respect to
all such assets and security interests and (ii) the conveyance provided for in
this Agreement shall be deemed to be an assignment and a grant pursuant to the
terms of this Agreement by the Depositor to the Trustee, for the benefit of the
Certificateholders, of a security interest in all of the assets that constitute
the Trust Fund, whether now owned or hereafter acquired.

         The Depositor for the benefit of the Certificateholders shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
assets of the Trust Fund, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of the Agreement. The Depositor shall
arrange for filing any Uniform Commercial Code continuation statements in
connection with any security interest granted or assigned to the Trustee for the
benefit of the Certificateholders.

         Section 10.06 Severability of Provisions.

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

         Section 10.07 Assignment.

         Notwithstanding anything to the contrary contained herein, except as
provided pursuant to Section 6.02, this Agreement may not be assigned by the
Master Servicer without the prior written consent of the Trustee and the
Depositor.

         Section 10.08 Limitation on Rights of Certificateholders.

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

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

         No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of an Event of Default and of the continuance thereof, as hereinbefore provided,
the Holders of Certificates evidencing not less than 25% of the Voting Rights
evidenced by the Certificates shall also have made written request to 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 60 days after its receipt of such notice,
request and offer of indemnity shall have neglected or refused to institute any
such action, suit or proceeding; it being understood and intended, and being
expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates, or to obtain or seek
to obtain priority over


                                       146

or preference to any other such Holder or to enforce any right under this
Agreement, except in the manner herein provided and for the common benefit of
all Certificateholders. For the protection and enforcement of the provisions of
this Section 10.08, each and every Certificateholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

         Section 10.09 Inspection and Audit Rights.

         The Master Servicer agrees that, on reasonable prior notice, it will
permit any representative of the Depositor, the Seller or the Trustee during the
Master Servicer's normal business hours, to examine all the books of account,
records, reports and other papers of the Master Servicer relating to the
Mortgage Loans, to make copies and extracts therefrom, to cause such books to be
audited by independent certified public accountants selected by the Depositor,
the Seller or the Trustee and to discuss its affairs, finances and accounts
relating to the Mortgage Loans with its officers, employees and independent
public accountants (and by this provision the Master Servicer hereby authorizes
such accountants to discuss with such representative such affairs, finances and
accounts), all at such reasonable times and as often as may be reasonably
requested. Any out-of-pocket expense incident to the exercise by the Depositor,
the Seller or the Trustee of any right under this Section 10.09 shall be borne
by the party requesting such inspection; all other such expenses shall be borne
by the Master Servicer.

         Section 10.10 Certificates Nonassessable and Fully Paid.

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

the case of each Mortgage Loan with respect to property located in the State of
California that is not a MERS Mortgage Loan, a duly executed assignment of the

representations as to: (i) the validity, legality, sufficiency, enforceability
or genuineness of any of the documents contained in each Mortgage File of any of

                               TRANSFER AFFIDAVIT



STATE OF                )
                        )    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 A-R Certificate (the "Certificate") issued
pursuant to the Pooling and Servicing Agreement, dated as of August 1, 2003 (the
"Agreement"), by and among CWABS, Inc., as depositor (the "Depositor"),
Countrywide Home Loans, Inc., as Seller, Countrywide Home Loans Servicing LP, as
Master Servicer, The Bank of New York, as Trustee and BNY Western Trust Company,
as Co-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. Either (a) the transferee is not an employee benefit plan that is
subject to Section 406 of ERISA or to section 4975 of the Internal Revenue Code
of 1986, nor is it acting on behalf of or with plan assets of any such plan, or
(b) the transferee has provided the opinion of counsel specified in Section
5.02(b) of the Agreement. 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 for its own account.

         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


                                      I-1

<PAGE>

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(c) 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(c) 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 I 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 Class
A-R Certificates.

         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 Class A-R Certificates may be
"noneconomic residual interests" 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. In addition, as the
holder of a noneconomic residual interest, the transferee may incur tax
liabilities in excess of any cash flows generated by the interest and the
transferee hereby represents that it intends to pay taxes associated with
holding the residual interest as they become due.

         11. The transferee has provided financial statements or other financial
information requested by the Transferor in connection with the transfer of the
Class A-R Certificates to permit the Transferor to assess the financial
capability of the transferee to pay such taxes.

                                      * * *

                               Certain Definitions

         "Ownership Interest": As to any Certificate, any ownership interest in
such Certificate, including any interest in such Certificate as the Holder
thereof and any other interest therein, whether direct or indirect, legal or
beneficial.

         "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 section 521 of the Code) that
is exempt from tax imposed by Chapter 1 of the Code (including the tax imposed
by section 511 of the Code on unrelated business taxable income) on any excess
inclusions (as defined in section 860E(c)(1) of the Code) with respect to any
Class A-R Certificate, (iv) rural electric and telephone cooperatives described
in section 1381(a)(2)(C) of the Code, (v) an "electing large partnership" as
defined in Section 775 of the Code, (vi) a Person that is not a citizen or
resident of the United States, a corporation, partnership, or other entity
(treated as a corporation or a partnership for federal income tax purposes)
created or organized in or under the laws of the United States, any state
thereof or the District of Columbia, or an estate whose income from sources
without the United 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, or a trust if a court within the
United States is able to exercise primary supervision over the administration of
the trust and one or more United States persons have authority to control all
substantial decisions of the trustor unless such Person has furnished the
transferor and the Trustee with a duly completed Internal Revenue Service Form
W-8ECI, and (vii) any other Person so designated by the Trustee based upon an
Opinion of Counsel that the Transfer of an Ownership Interest in a Class A-R
Certificate to such Person may cause the Trust Fund to fail to qualify as a
REMIC at any time that any Certificates are Outstanding. The terms "United
States," "State" and "International Organization" shall have the meanings set
forth in section 7701 of the Code or successor provisions. A corporation will
not be treated as an instrumentality of the United States or of any State or
political subdivision thereof for these purposes if all of its activities are
subject to tax and, with the exception of the Federal Home Loan Mortgage
Corporation, a majority of its board of directors is not selected by such
government unit.

         "Person": Any individual, corporation, partnership, limited liability
company, joint venture, association, joint-stock company, trust, unincorporated
organization or government, or any agency or political subdivision thereof.

         "Transfer": Any direct or indirect transfer or sale of any Ownership
Interest in a Certificate.

                        Section 5.02(C) of the Agreement
                        --------------------------------

                  (c) Each Person who has or who acquires any Ownership Interest
in a Class A-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 the rights of each Person acquiring any Ownership Interest in a Class A-R
Certificate are expressly subject to the following provisions:

                  (i) Each Person holding or acquiring any Ownership Interest in
         a Class A-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 Ownership Interest in a Class A-R Certificate may be
         registered on the Closing Date or thereafter transferred, and the
         Trustee shall not register the Transfer of any Class A-R Certificate
         unless, in addition to the representation letters required to be
         delivered to the Trustee under subparagraph (b) above, the Trustee
         shall have been furnished with an affidavit (a "Transfer Affidavit") of
         the initial owner or the proposed transferee in the form attached
         hereto as Exhibit I.

                  (iii) Each Person holding or acquiring any Ownership Interest
         in a Class A-R Certificate shall agree (A) to obtain a Transfer
         Affidavit from any other Person to whom such Person attempts to
         Transfer its Ownership Interest in a Class A-R Certificate, (B) to
         obtain a Transfer Affidavit from any Person for whom such Person is
         acting as nominee, trustee or agent in connection with any Transfer of
         a Class A-R Certificate and (C) not to Transfer its Ownership Interest
         in a Class A-R Certificate or to cause the Transfer of an Ownership
         Interest in a Class A-R Certificate to any other Person if it has
         actual knowledge that such Person is not a Permitted Transferee.

                  (iv) Any attempted or purported Transfer of any Ownership
         Interest in a Class A-R Certificate in violation of the provisions of
         this Section 5.02(c) shall be absolutely null and void and shall vest
         no rights in the purported transferee. If any purported transferee
         shall become a Holder of a Class A-R Certificate in violation of the
         provisions of this Section 5.02(c), then the last preceding Permitted
         Transferee shall be restored to all rights as Holder thereof
         retroactive to the date of registration of Transfer of such Class A-R
         Certificate. The Trustee shall be under no liability to any Person for
         any registration of Transfer of a Class A-R Certificate that is in fact
         not permitted by Section 5.02(b) and


                                      I-5

         Section 5.02(c) or for making any payments due on such 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 Transfer
         was registered after receipt of the related Transfer Affidavit,
         Transferor Certificate and either the Rule 144A Letter or the
         Investment Letter. The Trustee shall be entitled but not obligated to
         recover from any Holder of a Class A-R Certificate that was in fact not
         a Permitted Transferee at the time it became a Holder or, at such
         subsequent time as it became other than a Permitted Transferee, all
         payments made on such Class A-R Certificate at and after either such
         time. Any such payments so recovered by the Trustee shall be paid and
         delivered by the Trustee to the last preceding Permitted Transferee of
         such Certificate.

                  (v) The Depositor shall use its best efforts to make
         available, upon receipt of written request from the Trustee, all
         information necessary to compute any tax imposed under Section 860E(e)
         of the Code as a result of a Transfer of an Ownership Interest in a
         Class A-R Certificate to any Holder who is not a Permitted Transferee.

                  The restrictions on Transfers of a Class A-R Certificate set
forth in this Section 5.02(c) shall cease to apply (and the applicable portions
of the legend on a Class A-R Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee,
the Seller or the Master Servicer, to the effect that the elimination of such
restrictions will not cause any REMIC hereunder to fail to qualify as a REMIC at
any time that the Certificates are outstanding or result in the imposition of
any tax on the Trust Fund, a Certificateholder or another Person. Each Person
holding or acquiring any Ownership Interest in a Class A-R Certificate hereby
consents to any amendment of this Agreement that, based on an Opinion of Counsel
furnished to the Trustee, is reasonably necessary (a) to ensure that the record
ownership of, or any beneficial interest in, a Class A-R Certificate is not
transferred, directly or indirectly, to a Person that is not a Permitted
Transferee and (b) to provide for a means to compel the Transfer of a Class A-R
Certificate that is held by a Person that is not a Permitted Transferee to a
Holder that is a Permitted Transferee.

In connection with our disposition of the above-captioned 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

                           (i) the Master Servicer's determination that such
         waiver would maximize recovery of Liquidation Proceeds for such

         or

                           (ii)(A) the enforceability thereof is limited (1) by
         bankruptcy, insolvency, moratorium, receivership, or other similar law
         relating to creditors' rights generally or (2) due to acceleration in
