      POOLING AND SERVICING AGREEMENT, dated as of July 1, 2004, 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

                             PRELIMINARY STATEMENT:

      The Depositor intends to sell mortgage asset-backed pass-through
certificates (collectively, the "Certificates"), to be issued hereunder in
twelve 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 Corridor 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.

in the definition of Delay Delivery Mortgage Loans) (except as provided in
clause (vi) below) for the benefit of the Certificateholders, the following
documents or instruments with respect to each such Mortgage Loan so assigned
(with respect to each Mortgage Loan, clause (i) through (vi) below, together,

            (i) the original Mortgage Note, endorsed by the Seller or the
      originator of such Mortgage Loan, without recourse, in the following form:

      indicated thereon, or a copy of the Mortgage certified by the public
      recording office in which such Mortgage has been recorded;

            (iii) in the case of each Mortgage Loan that is not a MERS Mortgage
      Loan, a duly executed assignment of the Mortgage to "Asset-Backed
      Certificates, Series 2004-BC3, CWABS, Inc., by The Bank of New York, a New
      York banking corporation, as trustee under the Pooling and Servicing
      Agreement dated as of July 1, 2004, without recourse" (each such
      assignment, when duly and validly completed, to be in recordable form and
      sufficient to effect the assignment of and transfer to the assignee
      thereof, under the Mortgage to which such assignment relates);

            (iv) the original recorded assignment or assignments of the Mortgage

      event such original title policy has not been received from the insurer,
      such original or duplicate original lender's title policy and all riders
      thereto shall be delivered within one year of the Closing Date.

      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 so)
that such Mortgage Loans have been assigned by the Seller to the Trustee in
accordance with this Agreement for the benefit of the Certificateholders by
including (or deleting, in the case of Mortgage Loans which are repurchased in
accordance with this Agreement) in such computer files (a) the code "[IDENTIFY
TRUSTEE SPECIFIC CODE]" in the field "[IDENTIFY THE FIELD NAME

                                       54
<PAGE>

FOR TRUSTEE]" which identifies the Trustee and (b) the code "[IDENTIFY SERIES
SPECIFIC CODE NUMBER]" in the field "Pool Field" which identifies the series of
the Certificates issued in connection with such Mortgage Loans. The Seller
further agrees that it will not, and will not permit the Master Servicer to, and
the Master Servicer agrees that it will not, alter the codes referenced in this
paragraph with respect to any Mortgage Loan during the term of this Agreement
unless and until such Mortgage Loan is repurchased in accordance with the terms
of this Agreement.

      In the event that in connection with any Mortgage Loan that is not a MERS
Mortgage Loan the Seller cannot deliver the original recorded Mortgage or all
interim recorded assignments of the Mortgage satisfying the requirements of
clause (ii), (iii) or (iv) concurrently with the execution and delivery hereof,
the Seller shall deliver or cause to be delivered to the Trustee a true copy of
such Mortgage and of each such undelivered interim assignment of the Mortgage
each certified by the Seller, the applicable title company, escrow agent or
attorney, or the originator of such Mortgage, as the case may be, to be a true
and complete copy of the original Mortgage or assignment of Mortgage submitted
for recording. For any such Mortgage Loan that is not a MERS Mortgage Loan the
Seller shall promptly deliver or cause to be delivered to the 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
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
and complete by such recording office, shall satisfy the Seller's obligations in
Section 2.01. If any document submitted for recording pursuant to this Agreement
is (x) lost prior to recording or rejected by the applicable recording office,
the Seller shall immediately prepare or cause to be prepared a substitute and
submit it for recording, and shall deliver copies and originals thereof in
accordance with the foregoing or (y) lost after recording, the Seller shall
deliver to the 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
Trustee (x) from time to time additional original documents evidencing an
assumption or modification of a Mortgage Loan and (y) any other documents
required to be delivered by the Depositor or the Master Servicer to the Trustee
within the time periods specified in this Section 2.01.

      With respect to each Mortgage Loan other than a MERS Mortgage Loan as to
which the related Mortgaged Property and Mortgage File are located in (a) the
State of California or (b) any other jurisdiction under the laws of which the
recordation of the assignment specified in clause (iii) above is not necessary
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

                                       55
<PAGE>

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 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 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 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 Release in the
form of Exhibit M, the Trustee shall complete the assignment of the related
Mortgage in the manner specified in clause (iii) of the second paragraph of this
Section 2.01.

      So long as the Trustee maintains an office in the State of California, the
Trustee shall maintain possession of and not remove or attempt to remove from
the State of California any of the Mortgage Files as to which the related
Mortgaged Property is located in such State. In the event that the Seller fails
to record an assignment of a Mortgage Loan as herein provided within 90 days of
notice of an event set forth in clause (i), (ii) or (iii) of the above
paragraph, the Master Servicer shall prepare and, if required hereunder, file
such assignments for recordation in the appropriate real property or other
records office. The Seller hereby appoints the Master Servicer (and any
successor servicer hereunder) as its attorney-in-fact with full power and
authority acting in its stead for the purpose of such preparation, execution and
filing.

      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 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

                                       56
<PAGE>

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 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 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 thirty (30) days after 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 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

                                       57
<PAGE>

Mortgage Loans substantially in the form annexed hereto as Exhibit G-3, with any
applicable exceptions noted thereon. The Trustee 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 Trustee 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 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; 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 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

      holder of any Mortgage has modified the Mortgage in any material respect
      (except that a Mortgage Loan may have been modified by a written
      instrument that has been recorded or submitted for recordation, if

      was issued by a title insurer qualified to 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 Freddie Mac,
      which policy insures the Seller and successor owners of indebtedness
      secured by the insured Mortgage, as to the first priority lien, of the
      Mortgage subject to the exceptions set forth in paragraph (iv) above and
      against any loss by reason of the invalidity or unenforceability of the
      lien resulting from the provisions of the Mortgage providing for
      adjustment in the mortgage interest rate and/or monthly payment; to the
      best of the Seller's knowledge, no claims have been made under such
      mortgage title insurance policy and no prior holder of the related
      Mortgage, including the Seller, has done, by act or omission, anything
      that would impair the coverage of such mortgage title insurance policy.

            (xix) No Mortgage Loan was the subject of a Principal 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

      have been made or obtained

                                       63

      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

      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

                                       66
<PAGE>

      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 September 1,
      2004.

            (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.

                                       67
<PAGE>

            (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 4.500% per annum to 11.890% per annum
      and the weighted average Mortgage Rate as of the Cut-off Date was 6.99%
      per annum. The Mortgage Rates borne by the Mortgage Loans in Loan Group 2
      as of the Cut-off Date ranged from 4.900% per annum to 9.990% per annum
      and the weighted average Mortgage Rate as of the Cut-off Date was 6.63%
      per annum.

            (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 3.375% to
      10.690% and the weighted average Gross Margin was approximately 6.16%. The
      Gross Margins on the Adjustable Rate Mortgage Loans that are Mortgage
      Loans in Loan Group 2 range from approximately 3.750% to 9.040% and the
      weighted average Gross Margin was approximately 5.75%.

            (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).

                                       68
<PAGE>

            (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.

            (lxii)No Mortgage Loan is classified as (a) a high cost mortgage
      loan under the Home Ownership and Equity Protection Act of 1994 or (b) a
      "high cost" loan under any other applicable state, federal or local law.

            (lxiii) No Mortgage Loan is a High Cost Loan or Covered Loan, as
      applicable (as such terms are defined in Standard & Poor's LEVELS(R)
      Glossary, Version 5.6 Revised, Appendix E, attached hereto as Exhibit U)
      and no Mortgage Loan originated on or after October 1, 2002 through March
      6, 2003 is governed by the Georgia Fair Lending Act.

      (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

                                       69
<PAGE>

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 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.

                                       70
<PAGE>

      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 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 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 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 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

                                       71
<PAGE>

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 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 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

                                       72
<PAGE>

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 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.

                                       73
<PAGE>

      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 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 any REMIC 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

                                       75
<PAGE>

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

      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.

      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 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

                                       77
<PAGE>

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;

            (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

                                       78
<PAGE>

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 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 August 2004, 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) [reserved]

      (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

                                       79
<PAGE>

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

                                       80
<PAGE>

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 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,
                   Distribution Account and the Carryover Reserve Fund.

      (a) The Master Servicer may from time to time make withdrawals from the
Certificate Account for the following purposes:

      (i) to pay to the Master Servicer (to the extent not previously paid to or
withheld by the Master Servicer), as servicing compensation in accordance with
Section 3.15, that portion of any payment of interest that equals the Servicing
Fee for the period with respect to which such interest payment was made, and, as
additional servicing compensation, those other amounts set forth in Section
3.15;

      (ii) to reimburse each of the Master Servicer and the Trustee for Advances
made by it with respect to the Mortgage Loans, such right of reimbursement
pursuant to this subclause (ii) being limited to amounts received on particular
Mortgage Loan(s) (including, for this purpose, Liquidation Proceeds and
Subsequent Recoveries) 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 for any
Nonrecoverable Advance previously made by it;

      (iv) to reimburse the Master Servicer from Insurance Proceeds for Insured
Expenses covered by the related Required Insurance Policy;

                                       81
<PAGE>

      (v) to pay the Master Servicer any unpaid Servicing Fees and to reimburse
it for any unreimbursed Servicing Advances, the Master Servicer's right to
reimbursement of Servicing Advances pursuant to this subclause (v) with respect
to any Mortgage Loan being limited to amounts received on particular Mortgage
Loan(s) (including, for this purpose, Liquidation Proceeds and Subsequent
Recoveries and purchase and repurchase proceeds) that represent late recoveries
of the payments for which such advances were made pursuant to Section 3.01 or
Section 3.06;

      (vi) to pay to the Seller, the Depositor or the Master Servicer, as
applicable, with respect to each Mortgage Loan or property acquired in respect
thereof that has been purchased pursuant to Section 2.02, 2.03 or 3.12, all
amounts received thereon and not taken into account in determining the related
Stated Principal Balance of such repurchased Mortgage Loan;

      (vii) to reimburse the Seller, the Master Servicer or the Depositor for
expenses incurred by any of them in connection with the Mortgage Loans or
Certificates and reimbursable pursuant to Section 6.03 hereof provided that such

Account for deposit into the Distribution Account pursuant to the following
paragraph;

      (viii) to withdraw pursuant to Section 3.05 any amount deposited in the
Certificate Account and not required to be deposited therein; and

      (ix) to clear and terminate the Certificate Account upon termination of
this Agreement pursuant to Section 9.01 hereof.

      In addition, no later than 1:00 p.m. Pacific time on the Distribution
Account Deposit Date, the Master Servicer shall withdraw from the Certificate
Account and remit to the Trustee the Interest Remittance Amount and the
Principal Remittance Amount for each Loan Group for such Distribution Date to
the extent on deposit in the Certificate Account, and the Trustee shall deposit
such amount in the Distribution Account.

      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:

                                       82
<PAGE>

            (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 the Trustee the Trustee Fee on each Distribution Date;

            (iii) to withdraw pursuant to Section 3.05 any amount deposited in
      the Distribution Account and not required to be deposited therein;

            (iv) 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;

            (v) 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

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

      (c) The Trustee shall withdraw funds from the Carryover Reserve Fund for

(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

      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

                                       83
<PAGE>

or deed in lieu of foreclosure of any Mortgage 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 into a substitution of liability agreement with such Person,
pursuant to which the original Mortgagor is released from liability and such

                                       84
<PAGE>

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 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 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

                                       85
<PAGE>

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 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

                                       86
<PAGE>

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.

      (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.

                                       87
<PAGE>

      (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 during
any Calendar Quarter at a price equal to the Purchase Price; provided, however,
that the Master Servicer may only exercise this right during the period
beginning on the first Business Day of the following Calendar Quarter, and
ending at the close of business on the second-to-last Business Day of such
following Calendar Quarter 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 the Trustee for deposit in the Certificate
Account and the Trustee, upon receipt of such deposit and a Request for Release
from the Master Servicer in the form 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 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
manner customary for such purposes, the Master Servicer will promptly notify the
Trustee by delivering a Request for Release substantially in the form of Exhibit
N. Upon receipt of such request, the Trustee shall promptly release the related
Mortgage File to the Master Servicer, and the Trustee shall at the Master
Servicer's direction execute and deliver to the Master Servicer the request for
reconveyance, deed of reconveyance or release or satisfaction of mortgage or
such instrument releasing the lien of the Mortgage in each case provided by the
Master Servicer, together with the Mortgage Note with written evidence of
cancellation thereon. The Master Servicer is authorized to cause the removal
from the registration on the MERS(R) System of such Mortgage and to execute and
deliver, on behalf of the Trust Fund and the Certificateholders or any of them,
any and all instruments of satisfaction or cancellation or of partial or full
release. No expenses incurred in connection with any instrument of satisfaction
or deed of reconveyance shall be chargeable to the Certificate Account, the
Distribution Account, the Carryover Reserve Fund or the related subservicing
account. From time to time and as shall be appropriate for the servicing or
foreclosure of any Mortgage Loan, including for such purpose, collection under
any policy of flood insurance any fidelity bond or errors or omissions policy,
or for the purposes of effecting a partial release of any Mortgaged Property
from the lien of the Mortgage or the making of any corrections to the Mortgage
Note or the Mortgage or any of the other documents included in the Mortgage
File, the Trustee shall, upon delivery to the 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

                                       88
<PAGE>

Mortgage File or documents so released to be returned to the 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 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
signature, as appropriate, any court pleadings, requests for trustee's sale or
other documents necessary to effectuate such foreclosure or any legal action
brought to obtain judgment against the Mortgagor on the Mortgage Note or the
Mortgage or to obtain a deficiency judgment or to enforce any other remedies or
rights provided by the Mortgage Note or the Mortgage or otherwise available at
law or in equity. Notwithstanding the foregoing, the Master Servicer shall cause
possession of any Mortgage File or of the documents therein that shall have been
released by the Trustee to be returned to the Trustee within 21 calendar days
after possession thereof shall have been released by the Trustee unless (i) the
Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the
Mortgage Loan have been deposited in the Certificate Account, and the Master
Servicer shall have delivered to the Trustee a Request for Release in the form
of Exhibit N or (ii) the Mortgage File or document shall have been delivered to
an attorney or to a public trustee or other public official as required by law
for purposes of initiating or pursuing legal action or other proceedings for the
foreclosure of the Mortgaged Property and the Master Servicer shall have
delivered to the Trustee an Officer's Certificate of a Servicing Officer
certifying as to the name and address of the Person to which the Mortgage File
or the documents therein were delivered and the purpose or purposes of such
delivery.

      Section 3.14 Documents, Records and Funds in Possession of Master Servicer
                   to be Held for the Trustee.

      Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the 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, Subsequent Recoveries
or Insurance Proceeds in respect of any Mortgage Loan. All Mortgage Files and
funds collected or held by, or under the control of, the Master Servicer in
respect of any Mortgage Loans, whether from the collection of principal and
interest payments or from Liquidation Proceeds, including but not limited to,
any funds on deposit in the 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 Servicer also agrees that it shall not create,
incur or subject any Mortgage File or any funds that are deposited in the
Certificate Account, Distribution Account or Carryover Reserve Fund or in any
Escrow Account (as defined in 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 Mortgage File or any funds collected on,
or in connection with, a Mortgage Loan, except, however, that the Master
Servicer shall be entitled to

                                       89
<PAGE>

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

      Section 3.15 Servicing Compensation.

      As compensation for its activities hereunder, the Master Servicer shall be
entitled to retain or withdraw from the Certificate Account out of each payment
of interest on a Mortgage Loan included in the Trust Fund an amount equal to
interest at the applicable Servicing Fee Rate on the Stated Principal Balance of
the related Mortgage Loan for the period covered by such interest payment.

      Additional servicing compensation in the form of Excess Proceeds,
assumption fees, late payment charges, Prepayment Interest Excess, and all
income and gain net of any losses realized from Permitted Investments shall be
retained by the Master Servicer to the extent not required to be deposited in
the Certificate Account pursuant to Section 3.05 or 3.12(a) hereof. The Master
Servicer shall be required to pay all expenses incurred by it in connection with
its servicing activities hereunder (including payment of any premiums for hazard
insurance, as required by Section 3.10 hereof and maintenance of the other forms
of insurance coverage required by Section 3.10 hereof) and shall not be entitled
to reimbursement therefor except as specifically provided in Sections 3.08 and
3.12 hereof.

      Section 3.16 Access to Certain Documentation.

      The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of the Certificates or
Certificate Owners and the examiners and supervisory agents of the OTS, the FDIC
and such other authorities, access to the documentation regarding the Mortgage
Loans required by applicable regulations of the OTS and the FDIC. Such access
shall be afforded without charge, but only upon reasonable and prior written
request and during normal business hours at the offices of the Master Servicer
designated by it. Nothing in this Section shall limit the obligation of the
Master Servicer to observe any applicable law prohibiting disclosure of
information regarding the Mortgagors and the failure of the Master Servicer to
provide access as provided in this Section as a result of such obligation shall
not constitute a breach of this Section.

      Section 3.17 Annual Statement as to Compliance.

      The Master Servicer shall deliver to the Depositor and the Trustee on or
before the 80th day after the end of the Master Servicer's fiscal year,
commencing with its 2004 fiscal year, an Officer's Certificate stating, as to
the signer thereof, that (i) a review of the activities of the Master Servicer
during the preceding calendar year and of the performance of the Master Servicer
under this Agreement has been made under such officer's supervision and (ii) to
the best of such officer's knowledge, based on such review, the Master Servicer
has fulfilled all its obligations under this Agreement throughout such year, or,
if there has been a default in the fulfillment of any such obligation,
specifying each such default known to such officer and the nature and status
thereof and (iii) to the best of such officer's knowledge, each Subservicer has
fulfilled all its obligations under its Subservicing Agreement throughout such
year, or, if there has been a default in the fulfillment of any such obligation
specifying each such default known to

                                       90
<PAGE>

such officer and the nature and status thereof. The Trustee shall forward a copy
of each such statement to each Rating Agency. Copies of such statement shall be
provided by the Trustee to any Certificateholder upon request at the Master
Servicer's expense, provided such statement is delivered by the Master Servicer
to the Trustee.

      Section 3.18 Annual Independent Public Accountants' Servicing Statement;
                   Financial Statements.

      On or before the later of (i) the 80th day after the end of the Master
Servicer's fiscal year, commencing with its 2004 fiscal year or (ii) within 30
days of the issuance of the annual audited financial statements beginning with
the audit for the period ending in 2004, the Master Servicer at its expense
shall cause a nationally recognized firm of independent public accountants (who
may also render other services to the Master Servicer, the Seller or any
affiliate thereof) that is a member of the American Institute of Certified
Public Accountants to furnish a report to the Trustee, Depositor and the Seller
in compliance with the Uniform Single Attestation Program for Mortgage Bankers.
Copies of such report shall be provided by the Trustee to any Certificateholder
upon request at the Master Servicer's expense, provided such report is delivered
by the Master Servicer to the Trustee. Upon written request, the Master Servicer
shall provide to the Certificateholders its publicly available annual financial
statements (or, for so long as Countrywide Home Loans Servicing LP is the Master
Servicer hereunder, the Master Servicer's parent company's publicly available
annual financial statements), if any, promptly after they become available.

      Section 3.19 The Corridor Contracts.

      The Seller shall assign all of its right, title and interest in and to the
interest rate cap transactions evidenced by the Corridor Contracts to, and shall
cause all of its obligations in respect of such transaction to be assumed by,
the Trustee on behalf of the Trust Fund, on the terms and conditions set forth
in the Corridor Contract Assignment Agreements. The Corridor Contracts will be
assets of the Trust Fund but will not be assets of any REMIC. The Master
Servicer, on behalf of the Trustee, shall deposit any amounts received from time
to time with respect to the Corridor Contracts into the Carryover Reserve Fund.
The parties hereto acknowledge and agree that the Trustee is directed and
authorized by the Depositor to sign the Corridor Contract Assignment Agreements
and shall be fully protected in relying thereon. The representations made by the
Bank of New York as Assignee under the Corridor Contract Assignment Agreements
are made by the Trustee on behalf of, and solely as Trustee (and not in its
individual capacity) for the Trust Fund. The representations made by the Bank of
New York as Assignee under the Corridor Contract Assignment Agreements are made
by the Trustee on behalf of, and solely as Trustee (and not in its individual
capacity) for the Trust Fund.

      The Master Servicer, on behalf of the Trustee, shall prepare and deliver
any notices required to be delivered under the Corridor Contracts.

      The Master Servicer, on behalf of the Trustee, shall act as calculation
agent and/or shall terminate the Corridor Contracts, in each case upon the
occurrence of certain events of default or termination events to the extent
specified thereunder. Upon any such termination, the Corridor Contract
Counterparty will be obligated to pay the Trustee or the Master Servicer for the
benefit

                                       91
<PAGE>

of the Trust Fund an amount in respect of such termination. Any amounts
received by the Trustee or the Master Servicer for the benefit of the Trust
Fund, as the case may be, in respect of such termination shall be deposited and
held in the Carryover Reserve Fund to pay Net Rate Carryover for the applicable
Certificates (by deposit of the amount of any such Net Rate Carryover in the
Carryover Reserve Fund for payment to the related Certificateholders) as
provided in Section 4.04(a) on Distribution Dates following such termination to
and including the Cap Contract Termination Date. On the related Corridor
Contract Termination Date, after all other distributions on such date, if any
such amounts in respect of early termination remain in the Carryover Reserve
Fund, such amounts shall be distributed by the Trustee to the Class C
Certificateholder.

      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
later than the third Business Day following the immediately succeeding
Determination Date with a copy to the Class P Certificateholders. If the Master
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.

      (c) The Seller represents and warrants to the Depositor and the 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 accordance with its
terms under applicable state law, except as the enforceability thereof is
limited due to acceleration in connection with a foreclosure or other
involuntary payment.

                                       92
<PAGE>

      (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)

                                       94
<PAGE>

terminate all of the rights and obligations of the Master Servicer under this
Agreement in accordance 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.

      Section 4.03 [Reserved]

      Section 4.04 Distributions

Reserve Fund. The Carryover Reserve Fund shall be an Eligible Account, and funds
on deposit therein shall be held separate and apart from, and shall not be
commingled with, any other moneys, including without limitation, other moneys
held by the Trustee pursuant to this Agreement.

      (b) The Trustee shall make withdrawals from the Carryover Reserve Fund to
make distributions of amounts payable from each Corridor Contract to the related

Corridor Contract is subject to early termination, early termination payments
received on such Corridor Contract will be held by the Trustee until the related
Corridor Contract Termination Date and deposited in the Carryover Reserve Fund

Certificates. The Class C Certificates shall evidence ownership of the Carryover
Reserve Fund for federal tax purposes and the Holders thereof evidencing not

writing as to the investment of amounts therein. In the absence of such written
direction, all funds in the Carryover Reserve Fund shall be invested by the
Trustee in The Bank of New York cash reserves.

      Regular Interest ending with the designation "SUB," so that the
      Uncertificated Principal Balance of each such REMIC I Regular Interest is

      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

      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.

            (b) Notwithstanding the distributions described in this Section
      4.09, distribution of funds shall be made only in accordance with Section
      4.04.

      Section 4.10 [Reserved].

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

      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

      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 information as shall
be necessary to satisfy the condition to eligibility set

                                      110
<PAGE>

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 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
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 representation from the transferee of such Certificates that (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 the Class C
Certificates or the Class P Certificates if such Certificates have been offered
in a placement or underwriting which meets the requirements of the Underwriter's
Exemption, a representation that the purchaser is an insurance company which is
purchasing such Certificates with funds contained in or "insurance company
general account" (as such term is defined in Section V(e) of PTCE 95-60) and the
conditions of sections I and III of PTCE 95-60 have been satisfied, or 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 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

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 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 other than 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
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.

                                      112
<PAGE>

            (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.

                                      113
<PAGE>

      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

                                      114
<PAGE>

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.

                                      115
<PAGE>

      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 or (b) 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.

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

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 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.

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

hereby imposed on it except upon determination that its duties hereunder are no
longer permissible under applicable law. Any such determination permitting the

to such effect delivered to the Trustee. No such resignation shall become

obligations hereunder.

                     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

                                      119
<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 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
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

                                      120
<PAGE>

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 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 and warrant
that it is a member of MERS in good standing and shall agree to comply in all
material respects with the rules and procedures of MERS in connection with the
servicing of the Mortgage Loans that are registered with MERS, or (ii) the
predecessor Master Servicer shall cooperate with the successor Master Servicer
in causing MERS to execute and deliver an assignment of Mortgage in recordable
form to transfer the Mortgage from MERS to the Trustee and to execute and
deliver such other notices, documents

                                      121
<PAGE>

and other instruments as may be necessary or desirable to effect a transfer of
such Mortgage Loan or servicing of such Mortgage Loan on the MERS(R) System to
the successor Master Servicer. The predecessor Master Servicer shall file or
cause to be filed any such assignment in the appropriate recording office. The
successor Master Servicer shall cause such assignment to be delivered to the
Trustee or the Custodian promptly upon receipt of the original with evidence of
recording thereon or a copy certified by the public recording office in which
such assignment was recorded.

      Section 7.03 Notification to Certificateholders.

      (a) Upon any termination of or appointment of a successor to the Master
Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders and to each Rating Agency.

      (b) Within 60 days after the occurrence of any Event of Default, the
Trustee shall transmit by mail to all Certificateholders notice of each such
Event of Default hereunder known to the Trustee, unless such Event of Default
shall have been cured or waived.

                             CONCERNING THE 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 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 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

                                      123
<PAGE>

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 or
actual knowledge of a Responsible Officer of the Trustee that (A) such Advance
was not made by the Master Servicer and (B) that such Advance is not a
Nonrecoverable Advance.

      Section 8.02 Certain Matters Affecting the Trustee.

      (a) Except as otherwise provided in Section 8.01:

            (i) the Trustee may request and rely upon and shall be protected in
      acting or refraining from acting upon any resolution, Officer's
      Certificate, certificate of auditors or any other certificate, statement,
      instrument, opinion, report, notice, request, consent, order, appraisal,
      bond or other paper or document 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, the
      Trustee shall not be bound to make any investigation into the facts or
      matters stated in any resolution, certificate, statement, instrument,
      opinion, report, notice, request, consent, order, approval, bond or other
      paper or document, unless requested in writing so to do by Holders of 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;

                                      124
<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
the Mortgage Loans or deposited in or withdrawn from the Certificate Account by
the Depositor or the Master Servicer.

      Section 8.04 Trustee May Own Certificates.

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

      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

                                      125
<PAGE>

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

                                      126
<PAGE>

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 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

                                      127
<PAGE>

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:

      (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;

                                      128
<PAGE>

      (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 Investment Conduit Income Tax Returns
(Form 1066 or any successor form adopted by the Internal Revenue Service) and
prepare and file or cause to be prepared and filed with the Internal Revenue
Service and applicable state or local tax 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 telephone number of the person that the
holders of the Certificates may contact 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

                                      129
<PAGE>

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 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.

                                      130
<PAGE>

      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-5
Certificates (pro rata), third, to the Class M-4 Certificates (pro rata),
fourth, to the Class M-3 Certificates (pro rata), fifth, to the Class M-2
Certificates (pro rata), sixth, to the Class M-1 Certificates (pro rata), and
seventh, to the Class 1-A Certificates and Class 2-A 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, Class M-1,
Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and
Class B Certificateholders to receive payments from the Carryover Reserve Fund
as rights in an interest rate cap contracts written by the Corridor Contract
Counterparty with respect to the Net Rate Carryover funded by the Corridor
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 an interest rate cap contract. For purposes of
determining the issue price of the REMIC II Regular Interests, the Trustee shall
assume that the Class I-A Corridor Contract, the Class 2-A Corridor Contract and
Subordinated Corridor Contract have values of $126,414, $48,808 and $50,918
respectively.

                                   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 plus one month's
accrued interest thereon at the applicable Mortgage Rate less the Servicing Fee
Rate, (ii) the lesser of (x) the appraised value of any REO Property as
determined by the higher of two appraisals completed by two independent
appraisers selected by the Master Servicer at the expense of the Master Servicer
and (y) the Stated Principal Balance of each Mortgage Loan related to any REO
Property and (iii) any remaining unpaid costs and damages incurred by the Trust
Fund that arises out of a violation of any predatory or abusive lending law that
also constitutes an actual breach of representation (xxxiv) of Section 2.03
hereof 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
Certificateholders of all amounts required to be distributed to them pursuant to
this Agreement. In no event shall the trusts created hereby continue beyond the
earlier of (i) the expiration of 21 years from the death of the survivor of the
descendants of Joseph P. Kennedy, the late Ambassador of the United States to
the Court of St. James', 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 aggregate 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 5 days
prior to the date

                                      132
<PAGE>

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 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 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.

      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

                                      133
<PAGE>

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.

      (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

                                      135
<PAGE>

described in (i), without the 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

OF THE PARTIES

                                      136
<PAGE>

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 10.05 Notices.

      (a) The Trustee shall use its best efforts to promptly provide notice to
each Rating Agency with respect to each of the following of which it has actual

            (ii) The occurrence of any Event of Default that has not been cured;

            (iii) The resignation or termination of the Master Servicer or the
      Trustee and the appointment of any successor;

            (iv) The repurchase or substitution of Mortgage Loans pursuant to
      Sections 2.02, 2.03, 2.04 and 3.12; and

            (v) The final payment to Certificateholders.

            (ii) Each annual statement as to compliance described in Section
      3.17; and

            (iii) Each annual independent public accountants' servicing report
      described in Section 3.18.

      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

                                      138
<PAGE>

      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 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

                                      139
<PAGE>

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.

      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.

            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 Mortgage in blank (each such assignment, when duly
            and validly completed, to be in recordable form and sufficient to
            effect the assignment of and transfer to the assignee thereof, under
            the Mortgage to which such assignment relates);

      (iv)  the original recorded assignment or assignments of the Mortgage
            together with all interim recorded assignments of such Mortgage
            [(noting the presence of a MIN in the case of each MERS Mortgage
            Loan)];

      (v)   the original or copies of each assumption, modification, written
            assurance or substitution agreement, if any, with evidence of

            thereof certified by the title company, with the original policy of
            title insurance to be delivered within one year of the Closing Date.

      In the event that in connection with any Mortgage Loan that is not a MERS
Mortgage Loan the Seller cannot deliver the original recorded Mortgage or all
interim recorded assignments of the Mortgage satisfying the requirements of
clause (ii), (iii) or (iv), as applicable, the Trustee has received, in lieu
thereof, a true and complete copy of such Mortgage and/or such assignment or
assignments of the Mortgage, as applicable, each certified by the Seller, the
applicable title company, escrow agent or attorney, or the originator of such
Mortgage Loan, as the case may be, to be a true and complete copy of the
original Mortgage or assignment of Mortgage submitted for recording.

documents, (i) such documents appear regular on their face and related 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" in
Section 1.01 of the Pooling and Servicing Agreement accurately reflects

                              )  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 July 1, 2004 (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 and The Bank of New York, as 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

                                      I-1
<PAGE>

regulated investment company, a real estate investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives and, except as
may be provided in Treasury Regulations, persons holding interests in
pass-through entities as a nominee for another Person.)

      5. The transferee has reviewed the provisions of Section 5.02(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

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 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,

                                      I-5
<PAGE>

      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.

such a rating, BSFP, using its good faith efforts, fails to find a person
acceptable to the Counterparty, which acceptance shall not be unreasonably
withheld, to whom all of BSFP's interests and obligations under this Agreement
shall be assigned at no cost to the Counterparty, and following which BSFP shall
be released from all further obligations under this Agreement, then,
notwithstanding paragraph (i) below, such failure shall constitute an Additional
Termination Event with BSFP as the Affected Party."

until the payment in full of the Notes (as defined in the Indenture) and the
expiration of a period of one year plus ten days (or, if longer, the applicable
preference period) following such payment.

(n) Additional Provisions. Notwithstanding the terms of Sections 5 and 6 of the
ISDA Form Master Agreement, the provisions of Sections 5(a)(ii), 5(a)(iii) and

it may have to set off, net, recoup or otherwise withhold or suspend or
condition payment or performance of any obligation between it and the other
party hereunder against any obligation between it and the other party under any
other agreements. The provisions for Set-off set forth in Section 6(e) of the

         APPENDIX U: Standard & Poor's Predatory Lending Categorization

         APPENDIX E: Standard & Poor's Predatory Lending Categorization

      Standard & Poor's has categorized loans governed by anti-predatory lending
laws in the Jurisdictions listed below into three categories based upon a
combination of factors that include (a) the risk exposure associated with the
assignee liability and (b) the tests and thresholds set forth in those laws.
Note that certain loans classified by the relevant statute as Covered are
included in Standard & Poor's High Cost Loan Category because they included
thresholds and tests that are typical of what is generally considered High Cost
by the industry.

Exhibit 4.1

THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED BY THE HOLDER HEREOF FOR
ITS OWN ACCOUNT FOR INVESTMENT WITH NO INTENTION OF MAKING OR CAUSING TO BE
MADE A PUBLIC DISTRIBUTION OF ALL OR ANY PORTION THEREOF. SUCH SECURITIES HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR ANY STATE SECURITIES

Warrant to Purchase Shares of Common Stock

PROTALEX, INC.

COMMON STOCK PURCHASE WARRANT

Void after September 18, 2008

     PROTALEX, INC., a New Mexico corporation (the “Company”), hereby certifies
that, for good and valuable consideration the receipt and sufficiency of which
is hereby acknowledged, (including any successors and assigns, “Holder”), is
entitled, subject to the terms set forth below, to purchase from the Company at
any time or from time to time on or before 5:00 PM Mountain time, on September
18, 2008 (the “Expiration Date”), () fully paid and nonassessable shares of
Common Stock of the Company, at the price of $2.40 per share (the “Exercise
Price”).

     As used herein the following terms, unless the context otherwise requires,
have the following respective meanings:

     (a) The term “Company” includes any corporation which shall succeed to or
assume the obligations of the Company hereunder.

     (b) The term “Common Stock” shall mean the Common Stock of the Company,
and any other securities or property of the Company or of any other person
(corporate or otherwise) which the Holder at any time shall be entitled to
receive on the exercise of this Warrant, in lieu of or in addition to Common
Stock, or which at any time shall be issuable in exchange for or in replacement
of Common Stock.

     1. Exercise of Warrant; Partial Exercise. Subject to the provisions of
Section 2 hereof, this Warrant may be exercised in full or in part by the
Holder by surrender of this Warrant, together with the Holder’s duly executed
form of subscription attached hereto as Schedule 1, to the Company at its
principal office, accompanied by payment, in cash or by certified or official
bank check payable to the order of the Company, of the aggregate exercise price
of the shares of Common Stock to be purchased hereunder. The exercise of this
Warrant pursuant to this Section 1 shall be deemed to have been effected
immediately prior to the close of business on the business day on which this
Warrant is surrendered to the Company as provided

 

 

in this Section 1, and at such time the person in whose name any
certificate for shares of Common Stock shall be issuable upon such exercise
shall be deemed to be the record holder of such Common Stock for all purposes.
As soon as practicable after the exercise of this Warrant, the Company at its
expense will cause to be issued in the name of and delivered to the Holder, or
as the Holder may direct, in conformance with this Warrant, a certificate or
certificates for the number of fully paid and nonassessable shares of Common
Stock to which the Holder shall be entitled on such exercise, and, if
applicable, a new warrant evidencing the balance of the shares remaining
subject to the Warrant.

     2. Net Issuance.

          2.1 Right to Convert. In addition to and without limiting the rights of
the Holder under the terms of this Warrant, the Holder shall have the right to
convert this Warrant (the “Conversion Right”) into shares of Common Stock as
provided in this Section 2 at any time or from time to time during the Exercise
Period. Upon exercise of the Conversion Right with respect to shares of Common
Stock subject to the Warrant (the “Converted Warrant Shares”), the Corporation
shall deliver to the Holder (without payment by the Holder of any exercise
price or any cash or other consideration) that number of shares of fully paid
and nonassessable Common Stock computed using the following formula:

	 	 	 	 	 	 
	X

	 	=
	 	Y (A - B)	 
	

	 	 	 	
 	 
	

	 	 	 	A	 
	

	 	 	 	 	 
	

	 	 	 	 
Where	 

	 	 	X = the number of shares of Common Stock to be delivered to Holder
	 
	 	 	Y = the number of Converted Warrant Shares
	 
	 	 	A = the fair market value of one share of the Corporation’s Common Stock
on the Conversion Date (as defined below)
	 
	 	 	B = the per share exercise price of the Warrant (as adjusted to the
Conversion Date)

No fractional shares shall be issuable upon exercise of the Conversion Right,
and if the number of shares to be issued determined in accordance with the
foregoing formula is other than a whole number, the Corporation shall pay to
the Holder an amount in cash equal to the fair market value of the resulting
fractional share on the Conversion Date (as defined below). Shares issued
pursuant to the Conversion Right shall be treated as if they were issued upon
the exercise of the Warrant.

          2.2 Method of Exercise. The Conversion Right may be exercised by the
Holder by the surrender of the Warrant at the principal office of the Company
together with a written statement specifying that the Holder thereby intends to
exercise the Conversion Right and indicating the total number of shares under
the Warrant that the Holder is exercising through the Conversion Right. Such
conversion shall be effective upon receipt by the Company of the Warrant
together with the aforesaid written statement, or on such later date as is
specified therein (the “Conversion Date”). Certificates for the shares
issuable upon exercise of the Conversion Right shall be delivered to the Holder
promptly following the Conversion Date.

2

 

          2.3 Determination of Fair Market Value. For purposes of this Warrant, the
fair market value of a share of Common Stock on the Conversion Date shall mean:

               2.3.1 If traded on a stock exchange, the fair market value of the Common
Stock shall be deemed to be the average of the closing selling prices of the
Common Stock on the stock exchange determined by the Board to be the primary
market for the Common Stock over the fifteen (15) trading day period ending on
the date prior to the Conversion Date, as such prices are officially quoted in
the composite tape of transactions on such exchange.

               2.3.2 If traded over-the-counter, the fair market value of the Common
Stock shall be deemed to be the average of the closing bid prices (or, if such
information is available, the closing selling prices) of the Common Stock over
the fifteen (15) trading day period ending on the date prior to the Conversion
Date, as such prices are reported by the National Association of Securities
Dealers through its NASDAQ system or any successor system (or other recognized
source of quotations).

               2.3.3 If there is no public market for the Common Stock, then the fair
market value shall be determined in good faith by the Board of Directors of the
Company; provided that if the exercise is in connection with a sale, lease,
transfer or conveyance of all or substantially all of the assets of the
Company, or a consolidation of the Company with, or merger of the Company with
or into, any person, then the fair market value shall be the value received in
respect of each share of Common Stock pursuant to such transaction.

     3. Adjustments to Exercise Price and Number of Shares to be Issued upon
Exercise. The Exercise Price and the number and kind of shares of Common Stock
(or any shares of stock or other securities which may be) issuable upon the
exercise of this Warrant and the exercise price hereunder shall be subject to
adjustment from time to time upon the happening of certain events, as follows.
To the extent that this Section 3 provides for an increase in the Exercise
Price, the number of shares of Common Stock issuable upon exercise shall be
proportionately decreased. To the extent that this Section 3 provides for a
decrease in the Exercise Price, the number of shares issuable upon exercise
shall be proportionately increased.

          3.1 Dividends, Distributions, Stock Splits or Combinations. If the
Company shall at any time or from time to time after the date hereof make or
issue, or fix a record date for the determination of holders of Common Stock
entitled to receive, a dividend or other distribution payable in additional
shares of Common Stock, then and in each such event the exercise price
hereunder then in effect shall be decreased as of the time of such issuance or,
in the event such a record date shall have been fixed, as of the close of
business on such record date, by multiplying the exercise price hereunder then
in effect by a fraction: (a) the numerator of which shall be the total number
of shares of Common Stock (assuming the conversion of all outstanding
securities of the Company that are convertible into Common Stock and the
exercise of all options and warrants to purchase Common Stock) issued and
outstanding immediately prior to the time of issuance or the close of business
on such record date; and (b) the denominator of which shall be the total number
of shares of Common Stock (assuming the conversion of all outstanding
securities of the Company that are convertible into Common Stock and the
exercise of all options and warrants to purchase Common Stock) issued and
outstanding immediately after the time of issuance or the close of business on
such record date. If the Company shall at

3

 

any time subdivide the outstanding shares of Common Stock, or if the
Company shall at any time combine the outstanding shares of Common Stock, then
the exercise price hereunder immediately shall be decreased proportionally (in
the case of a subdivision) or increased proportionally (in the case of a
combination). Any such adjustment shall become effective at the close of
business on the date the subdivision or combination becomes effective.

          3.2 Reclassification or Reorganization. If the Common Stock issuable upon
the exercise of this Warrant shall be changed into the same or different number
of shares of any class or classes of stock, whether by capital reorganization,
reclassification or otherwise (other than a subdivision or combination of
shares or stock dividend provided for in Section 3.1 above, or a
reorganization, merger, consolidation or sale of assets provided for in Section
3.3 below), then and in each such event the Holder shall be entitled to receive
upon the exercise of this Warrant the kind and amount of shares of stock and
other securities and property receivable upon such reorganization,
reclassification or other change to which a holder of the number of shares of
Common Stock issuable upon the exercise of this Warrant would have received if
this Warrant had been exercised immediately prior to such reorganization,
reclassification or other change, all subject to further adjustment as provided
herein.

          3.3 Merger, Consolidation or Sale of Assets. If at any time or from time
to time there shall be a capital reorganization of the Common Stock (other than
a subdivision, combination, reclassification or exchange of shares provided for
elsewhere in this Section 3) or a merger or consolidation of the Company with
or into another corporation, or the sale of all or substantially all of the
Company’s assets and properties to any other person or entity, then as a part
of such reorganization, merger, consolidation or sale, provision shall be made
so that the Holder shall thereafter be entitled to receive upon the exercise of
this Warrant, the number of shares of stock or other securities or property of
the Company, or of the successor corporation resulting from such
reorganization, merger, consolidation or sale, to which a holder of the number
of shares of Common Stock issuable upon the exercise of this Warrant would have
received if this Warrant had been exercised immediately prior to such
reorganization, merger, consolidation or sale; provided, that, as a condition
to any merger, consolidation, or sale of substantially all of the assets of the
Company, the Company shall require that the surviving corporation assume in
writing the obligations pursuant to this Warrant.

          3.4 Adjustment of Exercise Price for Dilutive Issuances. The Exercise
Price shall be subject to adjustment from time to time as follows:

               3.4.1 For purposes of this paragraph 3.4, the following definitions shall
apply:

                    A) “Excluded Stock” shall mean:

               (i) all shares of Common Stock issued and outstanding on the date of this
Warrant and all shares of Common Stock issued or issuable upon exercise of this
Warrant;

               (ii) all shares of Common Stock or other securities hereafter issued or
issuable to officers, directors, employees, scientific advisors or consultants
of the Company

4

 

pursuant to any employee or consultant stock offering, plan or arrangement
approved by the majority of the members of the Board of Directors of the
Company;

               (iii) all shares of Common Stock or other securities hereafter issued in
connection with or as consideration for the acquisition or licensing of
technology approved by the majority of the members of the Board of Directors of
the Company; and

               (iv) all shares of Common Stock or other securities issued in connection
with equipment leasing or equipment financing arrangements approved by the
majority of members of the Board of Directors of the Company.

                    A) “Options” means options to purchase or rights to subscribe for Common
Stock (other than Excluded Stock).

                    B) “Convertible Securities” means securities by their terms convertible
into or exchangeable for Common Stock (other than Excluded Stock) and options
to purchase or rights to subscribe for such convertible or exchangeable
securities.

                    C) “Purchase Rights” means Options and Convertible Securities.

                    D) “Dilutive Issuance” means an issuance of Purchase Rights or Common
Stock, which is not Excluded Stock, without consideration or for a
consideration per share less than the then applicable Exercise Price.
“Dilutive Issuance” excludes any stock dividend, subdivision or split-up, stock
combination, dividend or transaction described in Sections 3.1, 3.2, and 3.3.

               3.4.2 If the Company issues or is deemed to issue any Common Stock or
Purchase Rights in a Dilutive Issuance, the applicable Exercise Price in effect
after each such issuance shall be adjusted to a price equal to the following:
the applicable Exercise Price in effect immediately prior to the Dilutive
Issuance (the “Old Exercise Price”) multiplied by the quotient obtained by
dividing:

                    A) an amount equal to the sum of

                         (x) the total number of shares of Common Stock outstanding immediately
prior to the Dilutive Issuance plus the total number of shares of Common Stock
then issuable upon conversion of Convertible Securities and exercise of
outstanding options and warrants, plus

                         (y) the number of shares of Common Stock which the consideration received
by the Company upon the Dilutive Issuance would purchase at such Old Exercise
Price, by

                    B) the total number of shares of Common Stock outstanding immediately
after the Dilutive Issuance plus the total number of shares of Common Stock
issuable on conversion of Convertible Securities and exercise of outstanding
options and warrants.

5

 

               3.4.3 For purposes of any adjustment of the applicable Exercise Price
pursuant to Section 3.4.2 above, the following provisions shall be applicable:

                    A) In the case of the issuance of Common Stock for cash, the consideration
shall be deemed to be the amount of cash paid therefor after deducting any
discounts or commissions paid or incurred by this corporation in connection
with the issuance and sale thereof.

                    B) In the case of the issuance of Common Stock for a consideration in
whole or in part other than cash, the consideration other than cash shall be
deemed to be the fair market value thereof as determined in good faith and in
the exercise of reasonable judgment by the Board of Directors of the Company,
in accordance with generally accepted accounting principles; provided, however,
that if at the time of such determination, the Company’s Common Stock is traded
in the over-the-counter market or on a national or regional securities
exchange, such fair market value as determined by the Board of Directors of the
Company shall not exceed the aggregate “Current Market Price” (as defined
below) of the shares of Common Stock being issued.

                    C) In the case of the issuance of Purchase Rights in a Dilutive Issuance:

                         1) the aggregate maximum number of shares of Common Stock deliverable upon
exercise of Options shall be deemed to have been issued at the time such
Options were issued and for a consideration equal to the consideration
(determined in the manner provided in Section 3.4.3(A) and (B) above), if any,
received by the Company upon the issuance of such Options plus the minimum
purchase price provided for in such Options;

                         2) the aggregate maximum number of shares of Common Stock deliverable upon
conversion or exercise of or exchange for any Convertible Securities shall be
deemed to have been issued at the time such Convertible Securities were issued
and for a consideration equal to the consideration received by the Company for
any such Convertible Securities (excluding any cash received on account of
accrued interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by the Company upon the conversion or
exchange of such Convertible Securities (determined in the manner provided in
Section 3.4.3(A) and (B) above);

                         3) on any change in the number of shares of Common Stock deliverable upon
exercise of any such Purchase Rights or on any change in the minimum purchase
price of such Purchase Rights, other than a change resulting from the
antidilution provisions of such Purchase Rights, the applicable Exercise Price
shall forthwith be readjusted to such Exercise Price as would have been
obtained had the adjustment made upon (x) the issuance of such Purchase Rights
not exercised, converted or exchanged prior to such change, as the case may be,
been made upon the basis of such change or (y) the issuance of options or
rights related to such securities not converted or exchanged prior to such
change, as the case may be, been made upon the basis of such change; and

6

 

                         4) on the expiration of any Purchase Rights, the applicable Exercise Price
shall forthwith be readjusted to such Exercise Price as would have obtained had
the adjustment made upon the issuance of such Purchase Right been made upon the
basis of the issuance of only the number of shares of Common Stock actually
issued upon the exercise of such Purchase Rights.

               3.4.4 All calculations under this Section 3.4 shall be made to the nearest
cent or to the nearest one hundredth (1/100) of a share, as the case may be.

               3.4.5 For the purpose of any computation pursuant to this Section 3.4, the
“Current Market Price” at any date of one share of Common Stock, shall be
deemed to be the average of the highest reported bid and the lowest reported
offer prices on the preceding business day as reported by Nasdaq (or other
recognized source of quotations); provided, however, that if the Common Stock
is not traded in such manner that the quotations referred to in this clause
3.4.5 are available for the period required hereunder, Current Market Price
shall be determined in good faith and in the exercise of reasonable judgment by
the Board of Directors of the Company.

               3.4.6 No adjustment in the Exercise Price need be made if such adjustment
would result in a change in the Exercise Price of less than $0.01. Any
adjustment of less than $0.01 which is not made shall be carried forward and
shall be made at the time of and together with any subsequent adjustment which,
on a cumulative basis, amounts to an adjustment of $0.01 or more in the
Conversion Price.

               3.4.7 Any notice required by the provisions of this Section 3.4 to be
given to the holder of Warrants shall be deemed given if deposited in the
United States mail, postage prepaid, and addressed to each holder of record at
such holder’s address appearing on the books of the Company.

          3.5 Notice of Adjustments and Record Dates. Whenever the Exercise Price
or the number of shares of Common Stock purchasable hereunder shall be adjusted
pursuant to this Section 3 (or otherwise), the Company shall promptly notify
the Holder in writing of each adjustment or readjustment of the Exercise Price
hereunder and the number of shares of Common Stock (or any shares of stock or
other securities which may be) issuable upon the exercise of this Warrant.
Such notice shall state the adjustment or readjustment and show in reasonable
detail the facts on which that adjustment or readjustment is based. Upon (i)
any taking by the Company of a record of the holders of any class of securities
for the purpose of determining the holders thereof who are entitled to receive
any dividend or other distribution, or (ii) any acquisition or other capital
reorganization of the Company, any reclassification or recapitalization of the
capital stock of the Company, any merger or consolidation of the Company with
or into any other corporation, or any sale of all or substantially all of the
assets or any voluntary or involuntary dissolution, liquidation or winding up
of the Company, the Company shall mail to each holder of this Warrant at least
fifteen (15) days prior to the record date specified therein (or such shorter
period approved by a majority in interest of the holders of this Warrant) a
notice specifying (A) the date on which any such record is to be taken for the
purpose of such dividend or distribution and a description of such dividend or
distribution, (B) the date on which any such acquisition, reorganization,
reclassification, transfer, consolidation, merger, asset sale, dissolution,
liquidation or winding up is expected to become

7

 

effective, and (C) the date, if any, that is to be fixed as to when the
holders of record of Common Stock (or other securities) shall be entitled to
exchange their shares of Common Stock (or other securities) for securities or
other property deliverable upon such acquisition, reorganization,
reclassification, transfer, consolidation, merger, asset sale, dissolution,
liquidation or winding up.

     4. Nonassessable; Reservation of Shares. The Company covenants that all
shares of Common Stock which may be issued upon the exercise of rights
represented by this Warrant will, upon exercise of the rights represented by
this Warrant, be validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue thereof (other than taxes in
respect of any transfer requested by the Holder occurring contemporaneously
with such issue). During the period within which the rights represented by
this Warrant may be exercised, the Company shall at all times have authorized
and reserved for issuance sufficient shares of Common Stock to provide for the
exercise of the rights represented by this Warrant.

     5. Replacement of Warrant. On receipt by the Company of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of any such loss, theft or
destruction of this Warrant, on delivery of an indemnity agreement reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of such Warrant, the Company at its
expense will execute and deliver to the Holder, in lieu thereof, a new Warrant
of like tenor.

     6. Charges, Taxes and Expenses. Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant shall be made without charge to
the Holder for any issue or transfer tax or other incidental expense in respect
of the issuance of such certificate, all of which taxes and expenses shall be
paid by the Company.

     7. No Rights or Liability as a Shareholder. This Warrant does not entitle
the Holder hereof to any voting rights or other rights as a shareholder of the
Company. No provisions hereof, in the absence of affirmative action by the
Holder to purchase Common Stock, and no enumeration herein of the rights or
privileges of the Holder, shall give rise to any liability of the Holder as a
shareholder of the Company.

     8. No Impairment. The Company will not, by any voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Company, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may be necessary to protect the rights of the
Holder of this Warrant against the impairment of Holder’s right to exercise
this Warrant for the shares of Common Stock indicated above and giving effect
to the adjustments required under Section 5.

     9. Miscellaneous.

          9.1 Transfer of Warrant. This Warrant shall be transferable in accordance
with the provisions of Section 2(f) of the Securities Purchase Agreement (the
terms of which are incorporated herein by this reference) by and among the
Company, the Holder and certain other Buyers (as such term is defined in such
Securities Purchase Agreement).

8

 

          9.2 Successors and Assigns. Subject to the provisions of Sections 9.1 and
9.2, this Warrant and the rights evidenced hereby shall inure to the benefit of
and be binding upon the successors of the Company and the permitted successors
and assigns of the Holder hereof. The provisions of this Warrant are intended
to be for the benefit of the Holder and shall be enforceable by such Holder.

          9.3 No Impairment. The Company shall not by any action, including,
without limitation, amending its charter documents or through any
reorganization, reclassification, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other action, avoid or seek to
avoid the observance or performance of any of the terms of this Warrant, but
will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder against impairment. Without limiting the
foregoing, the Company shall take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock upon the exercise of this Warrant,
free and clear of all liens, and shall use its best efforts to obtain all such
authorizations, exemptions, or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Warrant.

          9.4 Titles and Subtitles. The titles and subtitles used in this Warrant
are for convenience only and are not to be considered in construing or
interpreting this Warrant.

          9.5 Notices. Any notice required or permitted under this Warrant shall be
sufficiently given or made if in writing and will be deemed to have been
delivered (i) upon receipt, when delivered personally; (ii) upon receipt, when

electronically generated and kept on file by the sending party); or (iii) one
(1) business day after deposit with a nationally recognized overnight delivery

          9.6 Attorneys’ Fees. If any action at law or in equity is necessary to
enforce or interpret the terms of this Warrant, the prevailing party shall be
entitled to reasonable attorneys’ fees, costs and disbursements in addition to
any other relief to which such party may be entitled.

          9.7 Amendments and Waivers. Any term of this Warrant may be amended and
the observance of any term of this Warrant may be waived (either generally or
in a particular instance and either retroactively or prospectively), with the
written consent of the Company and a majority in interest of the Holders of the
Warrants; provided that any such amendment that adversely affects the Holder in
a manner differently from the other holders of Warrants shall require the
separate consent of the Holder and the Company. Any amendment or waiver
effected in accordance with this Section 9.7 shall be binding upon the Holder
of this Warrant (and of any securities into which this Warrant is convertible),
each future Holder of all such securities, and the Company. The Holder
acknowledges that by the operation of this Section 9.7, the holders of a
majority in interest of the Notes will have the right and power to diminish or
eliminate certain rights of the Holder under this Agreement. The foregoing
shall not limit or otherwise affect the Holder’s right to waive any of such
Holder’s rights hereunder with respect to itself without obtaining the consent
of any other holders of Warrants.

          9.8 Remedies. The Holder of this Warrant, in addition to being entitle to
exercise its rights granted by law, including recovery of damages, shall be
entitled to specific performance of its rights provided under this Warrant.
The Company agrees that monetary damages would not be adequate compensation for
any loss incurred by reason of a breach by it of the provisions of this Warrant
and hereby agrees, in and action for specific performance, to waive the defense
that a remedy at law would be adequate.

          9.9 Severability. If one or more provisions of this Warrant are held to
be unenforceable under applicable law, such provision shall be excluded from
this Warrant and the balance of the Warrant shall be interpreted as if such
provision were so excluded and shall be enforceable in accordance with its
terms.

          9.10 Governing Law. This Warrant shall be governed by and construed and
enforced in accordance with the laws of the State of California, without giving
effect to its conflicts of laws principles.
