AMENDED AND RESTATED STOCK PLEDGE AGREEMENT

Exhibit 10.170

FORM OF

AMENDED AND RESTATED STOCK PLEDGE AGREEMENT

 

THIS AMENDED AND RESTATED STOCK PLEDGE AGREEMENT (this “Pledge Agreement”), is dated as of the 3rd day of August, 2001, made by Display Technologies, Inc., a Nevada corporation (“Display” or the “Pledgor”), in favor of SouthTrust Bank, an Alabama banking corporation (“Pledgee"), and amends and restates that Stock Pledge Agreement dated September 26, 2000 executed by Display, Ad Art Electronic Sign Corporation, a Florida corporation; DTEK Canada, Inc., a Florida corporation, and DTEK Signs, ULC, a Nova Scotia unlimited liability in favor of Pledgee (the “Original Stock Pledge Agreement").

W I T N E S S E T H:

WHEREAS, Display, Don Bell Industries, Inc., J.M Stewart Manufacturing, Inc., J.M. Stewart Corporation, J.M. Stewart Industries, Inc., Vision Trust Marketing, Inc., and Lockwood Sign Group, Inc., (collectively, the “Borrowers”) and the Pledgee have entered into a Loan and Security Agreement dated as of January 17, 2001 (as amended, the “Loan Agreement”);

WHEREAS, the obligations under the Loan Agreement are secured by, among other things, the Original Stock Pledge Agreement;

WHEREAS, Pledgor has executed and delivered to Pledgee a Guaranty of Payment of even date herewith (the “Guaranty”), pursuant to which Pledgor has guaranteed the payment and performance of all obligations of Ad Art Electronic Sign Corporation (“Ad Art”), a wholly owned subsidiary of Pledgor, under that certain Loan and Security Agreement dated January 17, 2001 between Ad Art and Pledgee, among others (as amended, the “Ad Art Loan Agreement”); and

WHEREAS, as an inducement to the Pledgee to amend the Loan Agreement pursuant to the terms and conditions of the Fourth Amendment to Loan and Security Agreement of even date herewith, and to continue to forbear from collection against Ad Art of the obligations due under the Ad Art Loan Agreement, by written amendment of even date herewith, the Pledgor has agreed to execute this Pledge Agreement, which amends and restates the Original Stock Pledge Agreement, and, pursuant hereto, to pledge the Pledged Stock, as defined in this Pledge Agreement, as security for the prompt payment and performance of all Obligations.

NOW, THEREFORE, in consideration of the foregoing, and intending to be legally bound hereby, the Pledgor hereby agrees with the Pledgee as follows:

1.      (a)      The term “Event of Default” as used in this Pledge Agreement means the occurrence of any of the following:

1

 

     

  
    

          (i)     
the occurrence of any Default or Event of Default under the Loan Agreement or under the Guaranty;

          (ii)
     the breach by the Pledgor of any of the covenants made by the Pledgor in this Pledge Agreement; or

          (iii)
    the material falsity of any of the representations or warranties made by the Pledgor in this Pledge Agreement on or as of the date when made, or at any time after the date when made if such representation or warranty subsequently becomes untrue and remains untrue for ten days or longer.

    

  

(b)   The term “Pledged Stock” as used in this Pledge Agreement means the shares of stock described in Schedule I hereto, together will all certificates, options, rights, warrants, dividends and other distributions now existing or hereafter issued, payable or arising as an addition to, in substitution or in exchange for, or on account of, any such shares, and all proceeds of all the foregoing, whether now or hereafter owned or acquired by the Pledgor.

(c)     The terms “Obligations” and “Secured Obligations” as used in this Pledge Agreement means, collectively, the “Obligations” as defined in the Loan Agreement, the “Guaranteed Obligations,” under the Guaranty, and all obligations of the Pledgor to pay money or perform acts under this Pledge Agreement.

(d)     All other capitalized terms used in this Pledge Agreement and not specifically defined herein shall have the respective meanings assigned to them in the Loan Agreement.

2.     (a)     
As security for the prompt payment and performance of the Obligations, the Pledgor hereby assigns, transfers and pledges the Pledged Stock to the Pledgee and grants to the Pledgee a lien thereon and security interest therein.

(b)      If the Pledgor shall become entitled to receive or shall receive, in connection with any of the Pledged Stock, any:

           
(i)
     stock certificates, including, but without limitation, any certificates representing a stock dividend or issued in connection with any increase or reduction of capital, reclassification, merger, consolidation, sale of assets, combination of shares, stock split, spin-off or split-off;

           
(ii)     options, warrants, or rights, whether as an addition to, or in substitution or in exchange for, any of the Pledged Stock, or otherwise;

2

 

     

           
(iii)
   dividends or distributions payable in property, including securities issued by other than the issuer of any of the Pledged Stock; or

          
(iv)
    cash dividends or distributions of any sort, except as otherwise provided in subparagraph (d) below with respect to cash dividends paid out of earned surplus,

the Pledgor shall accept the same as the Pledgee’s agent, in trust for the Pledgee, and shall deliver the same forthwith to the Pledgee in the exact form received with, as applicable, the Pledgor’s endorsement, when necessary, or appropriate stock powers duly executed in blank, to be held by the Pledgee, subject to the terms hereof, as part of the Pledged Stock.

(c)     At any time the Pledgee, at its option, may at its election have any or all of the Pledged Stock registered in its name or that of its nominee, and the Pledgor hereby covenants that, upon the Pledgee’s request, the Pledgor will cause the issuer, transfer agent, or registrar of the Pledged Stock to effect such registration. If that shall be done prior to the occurrence of an Event of Default, the Pledgor shall nevertheless retain all voting rights with respect to the Pledged Stock and, unless otherwise provided in the Loan Agreement or in subparagraph (d) below, all right to receive cash dividends paid out of earned surplus, and, for that purpose, the Pledgee shall execute and deliver to the Pledgor all necessary proxies and, unless otherwise so provided, shall endorse without recourse and deliver to the Pledgor all checks representing such dividends as and when received. Immediately and without further notice upon the occurrence of an Event of Default, whether or not the Pledged Stock shall have been registered in the name of the Pledgee or its nominee, the Pledgee or its nominee shall have, with respect to the Pledged Stock, the right to exercise all voting rights as to all of the Pledged Stock, to waive notice of stockholders’ meetings, to execute actions by written consent in lieu of a meeting, and all other corporate rights, and all conversion, exchange, subscription and other rights, privileges and options pertaining thereto as if it were the absolute owner thereof, including, without limitation, the right to exchange any or all of the Pledged Stock upon the merger, consolidation, reorganization, recapitalization or other readjustment of the issuer thereof, or upon the exercise by such issuer of any right, privilege, or option pertaining to any of the Pledged Stock, and, in connection therewith, to deliver any of the Pledged Stock to any committee, depository, transfer agent, registrar or other designated agency upon such terms and conditions as it may determine, all without liability except to account for property actually received by it; but the Pledgee shall have no duty to exercise any of the aforesaid rights, privileges or options and shall not be responsible for any failure to do so or any delay in so doing.

(d)     Unless an Event of Default shall have occurred and be continuing, and unless otherwise prohibited by the Loan Agreement, the Pledgor shall be entitled to receive for its own use cash dividends paid out of earned surplus. Upon the occurrence of an Event of Default, the Pledgee may at its election require any or all such cash dividends to be delivered to the Pledgee, and the Pledgor agrees upon request to deliver such dividends to the Pledgee as and when received, 

3

 

     

endorsed to the order of the Pledgee or in blank, to be cashed and held by the Pledgee as additional security hereunder or, at the Pledgee’s election, to be applied toward the payment or performance of the Secured Obligations. Pending delivery of such cash dividends to the Pledgee, the Pledgor agrees to hold the same as the Pledgee’s agent, in trust for the Pledgee.

(e)     The Pledgor warrants and will, at its own expense, defend the Pledgee’s right, title, special property and security interest in and to the Pledged Stock against the claims of any person, firm, corporation or other entity. This warranty and covenant shall survive the termination of this Pledge Agreement.

(f)     The Pledgor shall use its best efforts, upon the request of the Pledgee, to cause any issuer, transfer agent, or registrar of the Pledged Stock to take all such actions and execute all such documents as may be necessary or appropriate to remove any restrictive legends placed on the Pledged Stock that are not legally required for such Pledged Stock held by the Pledgee; after an Event of Default, effect any sale or sales of Pledged Stock in accordance with Rule 144 under the Securities Act; and (iii) after an Event of Default, effect any sale or other distribution of the Pledged Stock in any lawful public or private sale or other disposition.

3.     (a)
    Upon the occurrence of an Event of Default, the Pledgee may at its election, without demand of performance or other demand, advertisement, or notice of any kind (except the notice specified below of time and place of public or private sale and any other notice which is required by law and cannot be waived) to or upon the Pledgor or any other person (all of which are, to the extent permitted by law, hereby expressly waived), realize upon the Pledged Stock or any part thereof, and may sell or otherwise dispose of and deliver the Pledged Stock or any part thereof or interest therein, in one or more parcels, at public or private sale or sales, at any exchange, broker’s board or at any of the Pledgee’s offices or elsewhere, at such prices and on such terms (including, but without limitation, a requirement that any purchaser of all of any part of the Pledged Stock purchase the shares constituting the Pledged Stock for investment and without any intention to make a distribution thereof) as it may deem appropriate and as shall be commercially reasonable, for cash or on credit, or for future delivery without assumption of any credit risk, with the right in the Pledgee or any purchaser to purchase upon any such sale the whole or any part of the Pledged Stock free of any right or equity of redemption in the Pledgor.

(b)     The proceeds of any such disposition or other action by the Pledgee shall be applied as follows:

          (i)
     first, to the costs and expenses incurred in connection therewith or incidental thereto or in the care or safekeeping of any of the Pledged Stock or in any way relating to the rights of the Pledgee hereunder, including brokers’ fees and commissions and reasonable attorneys’ fees and legal expenses;

4

 

 

          (ii)
     second, to the payment and performance of the Secured Obligations;

          (iii)
    third, to the payment of any other amounts required by applicable law (including, without limitation, Section 9-504(1)(c) of the Uniform Commercial Code); and

          (iv)
    fourth, to the Pledgor or its transferees, to the extent of any surplus proceeds.

(c)     The Pledgee need not give more than five days’ notice of the time and place of any public sale or of the time after which any private sale may take place, which notice the Pledgor hereby agrees to be reasonable; provided, however, that the Pledgee at any time, without any notice to the Pledgor, may sell any of the Pledged Stock which is customarily sold on a recognized market.

(d)     The Pledgor recognizes that the Pledgee may be unable to effect a public sale of all or a part of the Pledged Stock and may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obligated to agree, among other things, to acquire the Pledged Stock for their own account, for investment and not with a view to the distribution or resale thereof. The Pledgor acknowledges that any such private sales may be at prices and on terms less favorable to the Pledgee than those of public sales, and agrees that such private sales shall be deemed to have been made in a commercially reasonable manner and that the Pledgee has no obligation to delay sale of any Pledged Stock to permit the issuer thereof to register it for public sale under the Securities Act.

4.     The Pledgor represents and warrants that:

(a)     it has, and has duly exercised, all requisite power and authority to enter into this Pledge Agreement, to pledge the Pledged Stock for the purposes described in paragraph 2(a), and to carry out the transactions contemplated by this Pledge Agreement;

(b)     it is the legal and beneficial owner of all of the Pledged Stock as per Schedule 1;

(c)     all of the shares of the Pledged Stock are owned by the Pledgor free of any pledge, mortgage, hypothecation, lien, charge, encumbrance or security interest in such shares or the proceeds thereof, except for that granted hereunder; 

(d)     upon delivery of the Pledged Stock to the Pledgee or its agent, this Pledge Agreement shall create a valid first lien upon and perfected security interest in the Pledged Stock and the proceeds thereof, subject to no prior security interest, lien, charge or encumbrance,

5

 

 

or agreement purporting to grant to any third party a security interest in the property or assets of the Pledgor which would include the Pledged Stock;

(e)      the execution and delivery of this Pledge Agreement, and the performance of its terms, will not result in any violation of any provision of the Pledgor’s articles or certificate of incorporation or by-laws, or violate or constitute a default under the terms of any agreement, indenture or other instrument, license, judgment, decree, order, law, statute, ordinance or other governmental rule or regulation, applicable to the Pledgor or any of its property; and

(f)      the shares of the Pledged Stock have been duly and validly issued, are fully paid and nonassessable, and constitute all of the issued and outstanding shares of each issuer thereof, except as otherwise set forth in the Schedule I hereto, and there are no outstanding warrants, actions, rights or other commitments (including, but without limitation, convertible notes or other convertible securities) entitling any person to purchase or otherwise acquire any such shares or any additional shares of such issuer.

5.     (a)
     The Pledgor will not, without the Pledgee’s written consent obtained in advance:

          (i)
     sell, give or otherwise dispose of any of the Pledged Stock or any interest therein or create, incur, or permit to exist any pledge, mortgage, lien, charge, encumbrance or any security interest whatsoever in, or with respect to, any of the Pledged Stock or the proceeds thereof, other than that created hereby; or

          (ii)
     consent to or approve the issuance of any additional shares of any class of capital stock by the issuer of the Pledged Stock; or any securities convertible voluntarily by the holder thereof or automatically upon the occurrence or nonoccurrence of any event or condition into, or exchangeable for, any such shares; or any warrants, options, rights, or other commitments entitling any person to purchase or otherwise acquire any such shares.

(b)     The Pledgor shall, upon the request of the Pledgee, promptly deliver to the Pledgee all written notices, and promptly give the Pledgee written notice of any other notices, received by the Pledgor with respect to Pledged Stock at any time after such request is made.

(c)     The Pledgor shall at any time, and from time to time, upon the request of the Pledgee, execute and deliver such further documents and do such further acts and things as the Pledgee may reasonably request to effect the purposes of this Pledge Agreement. 

(d)     The Pledgor shall, at any time and from time to time, execute in blank and deliver to the Pledgee an Irrevocable Stock Assignment and Power of Attorney, in substantially 

6

 

 

the form of Exhibit A hereto, with respect to each certificate or instrument now or hereafter evidencing the Pledged Stock.

(6)      (a)     If the Pledgee shall elect to exercise its right to sell or otherwise dispose of all or any part of the Pledged Stock, and if, in the opinion of counsel for the Pledgee, it is necessary to have the Pledged Stock or that portion thereof to be sold registered under the provisions of the Securities Act of 1933, as amended (the
“ Securities Act”), the Pledgor will use its best efforts to cause:

  

           (i)
     the issuer of the Pledged Stock and its directors and officers to take all action necessary to register the Pledged Stock or that portion thereof to be disposed of under the provisions of the Securities Act, at the Pledgor’s expense;

           (ii)      the registration statement relating thereto to become effective and to remain so for not less than one year from the date of the first public offering of the Pledged Stock or that portion thereof so to be disposed of, and to make all amendments thereto and to the related prospectus which, in the opinion of the Pledgee or its counsel, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto;

          (iii)
      the issuer of the Pledged Stock to comply with the provisions of the
“ Blue Sky” laws of any jurisdiction which the Pledgee shall designate; and

          (iv)
      the issuer of the Pledged Stock to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) covering a period of at least twelve months but no more than eighteen months beginning with the first month after the effective date of any such registration statement, which earnings statement will satisfy the provisions of Section 11(a) of the Securities Act.

  

(b)    The Pledgor acknowledges that a breach of any of the covenants contained in paragraph 6(a) above may cause irreparable injury to the Pledgee; that the Pledgee will have no adequate remedy at law with respect to such breach; and, as a consequence, that the Pledgor’s covenants in paragraph 6(a) shall be specifically enforceable against the Pledgor; and the Pledgor hereby waives, to the extent such waiver is enforceable under law, and agrees not to assert, any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred.

7

 

     

7.     (a)     Upon the occurrence of an Event of Default, the Pledgee agrees to deliver irrevocable proxies with respect to the Pledged Stock in form satisfactory to the Pledgee, and, until receipt of such separate proxies, this Pledge Agreement shall constitute the Pledgor’s proxy to the Pledgee or its nominee to vote all shares of Pledged Stock then registered in the Pledgor’s name at any and all such times as the Pledgee has the right to vote such shares pursuant to the terms of this Pledge Agreement. Such power of attorney granted hereby is coupled with an interest and is irrevocable.

(b)    Whenever any checks, drafts or other instruments are delivered to or come into the possession of the Pledgee and the Pledgee has the right at such time under this Pledge Agreement or otherwise to hold such writings or the sums evidenced thereby as additional security hereunder or to apply the same toward the payment or performance of the Obligations, the Pledgee is authorized to endorse such writings in the name of the Pledgor, and the Pledgor hereby irrevocably constitutes and appoints the Pledgee, its officers and agents, as its attorneys-in-fact for such purposes.

(8)     Upon the final, nonavoidable payment and performance in full of all of the Secured Obligations, the termination of all commitments of the Pledgee to lend money or otherwise extend credit under the Loan Agreement, the payment of all additional costs and expenses of the Pledgee as provided herein, and written demand for termination from the Pledgor to the Pledgee, the Pledgee shall deliver to the Pledgor a written termination of this Pledge Agreement and thereupon this Pledge Agreement (except paragraph 2(e) hereof with respect to any of the Pledged Stock sold or otherwise disposed of by the Pledgee) shall terminate and the Pledgee shall deliver to the Pledgor, at the Pledgor’s expense, such of the Pledged Stock as shall not have been sold or otherwise applied or disposed of pursuant to this Pledge Agreement. Until termination, this Pledge Agreement shall be a continuing agreement in every respect, even if from time to time there are no outstanding Secured Obligations.

(9)     Any notices or consents required or permitted by this Pledge Agreement shall be in writing and shall be deemed delivered if delivered in person or sent by certified mail, postage prepaid, return receipt requested, or facsimile, as follows, unless such address is changed by written notice hereunder:

  (a)    If to the Pledgor:

          10.    
(a)     Beyond the exercise of reasonable care to assure the safe custody of the Pledged Stock while held by it hereunder, the Pledgee shall have no duty or liability to preserve the value of the Pledged Stock or any rights pertaining thereto and shall be relieved of all responsibility for the Pledged Stock upon surrendering it or tendering surrender of it to the Pledgor.

(b)     No course of dealing between the Pledgor and the Pledgee, or any failure to exercise or any delay in exercising any right, power or privilege of the Pledgee hereunder or under the Loan Agreement, shall operate as a waiver of the Pledgee’s rights and remedies under the Pledge Agreement, the Loan Agreement, or applicable law; nor shall any single or partial exercise of any right, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

(c)    The rights and remedies provided herein and in the Loan Agreement and in all other agreements, instruments, and documents delivered pursuant to or in connection with the Loan Agreement or this Pledge Agreement are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law, including, without limitation, the rights and remedies of a secured party under the Uniform Commercial Code.

(d)The provisions of this Pledge Agreement are severable, and if any clause or provision shall be held invalid or unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such clause or provision or part thereof in such jurisdiction and shall not in any manner affect such clause or provision in any other jurisdiction or any other clause or provision of this Pledge Agreement in any jurisdiction.

(e)This Pledge Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns.

(f) If two or more persons or entities execute this Pledge Agreement as Pledgors, such Pledgors shall be jointly and severally bound and obligated hereunder, and the terms 
the “Pledgor” and “its” as used herein mean and include each such Pledgor and also all of such Pledgors.

(g) This Pledge Agreement shall be construed in accordance with the substantive law of the United States and the State of Alabama without regard to principles of 

9

 

     

conflicts of law, except to the extent that the application of the law of another jurisdiction is required to give effect to or to make enforceable any of the provisions hereof.

(h)The Pledgor hereby waives acceptance and notice of acceptance of this Pledge Agreement by the Pledgor and agrees that this Pledge Agreement will be fully effective when executed by the Pledgor and delivered to the Pledgee.

(i)This Pledge Agreement is intended to take effect as an instrument under seal.

IN WITNESS WHEREOF, the Pledgor has caused this Pledge Agreement to be duly executed and its seal to be affixed hereto on or as of the date and year first above written.

          This Pooling and Servicing Agreement is dated as of October 1, 2001
(the "Agreement"), among OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as
depositor (the "Depositor"), OPTION ONE MORTGAGE CORPORATION, as master servicer
(the "Master Servicer") and WELLS FARGO BANK MINNESOTA, N.A., as trustee (the
"Trustee").

                             PRELIMINARY STATEMENT:

          The Depositor intends to sell pass-through certificates (collectively,
the "Certificates"), to be issued hereunder in multiple classes, which in the
aggregate will evidence the entire beneficial ownership interest in the Trust
Fund created hereunder. The Certificates will consist of eight classes of
certificates, designated as (i) the Class A Certificates, (ii) the Class S
Certificates, (iii) the Class M-1 Certificates, (iv) the Class M-2 Certificates,
(v) the Class M-3 Certificates, (vi) the Class P Certificates, (vii) the Class C
Certificates and (viii) the Class R Certificates.

                                     -------

          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 subject to this Agreement (but exclusive of the Pre-Funding
Account, the Interest Coverage Account, the Initial Deposit Account, the Reserve
Fund and the Master Servicer Prepayment Charge Payment Amounts) as a real estate
investment conduit (a "REMIC") for federal income tax purposes, and such
segregated pool of assets will be designated as "REMIC 1." The Class R-1
Interest will represent the sole class of "residual interests" in REMIC 1 for
purposes of the REMIC Provisions under federal income tax law. The following
table irrevocably sets forth the designation, the Uncertificated REMIC 1
Pass-Through Rate, the initial Uncertificated Principal Balance, and solely for
purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the
"latest possible maturity date" for each of the REMIC 1 Regular Interests. None
of the REMIC 1 Regular Interests will be certificated.

hereof and, to the extent necessary, in Section 2.01(iv) hereof to be recorded;
PROVIDED, HOWEVER, the Depositor need not cause to be recorded any Assignment
which relates to a Mortgage Loan in any jurisdiction under the laws of which, as
evidenced by an Opinion of Counsel delivered by the Depositor to the NIMS
Insurer, the Trustee and the Rating Agencies on or before the Closing Date, the
recordation of such assignment is not necessary to protect the Trustee's
interest in the related Mortgage Loan; PROVIDED, HOWEVER, notwithstanding the
delivery of any Opinion of Counsel, each Assignment shall be submitted for
recording by the Depositor in the manner described above, at no expense to the
Trust Fund or Trustee, upon the earliest to occur of: (i) reasonable direction
by Holders of Certificates entitled to at least 25% of the Voting Rights, (ii)
the occurrence of a Master Servicer Event of Termination, (iii) the occurrence
of a bankruptcy, insolvency or foreclosure relating to the Master Servicer, (iv)
the occurrence of a servicing transfer as described in Section 7.02 hereof, (v)
if the Originator is not the Master Servicer and with respect to any one
Assignment the occurrence of a bankruptcy, insolvency or foreclosure relating to
the Mortgagor under the related Mortgage and (vi) any Mortgage Loan that is 90
days or more Delinquent. Notwithstanding the foregoing, if the Originator fails
to pay the cost of recording the Assignments, such expense will be paid by the
Trustee and the Trustee shall be reimbursed for such expenses by the Trust. The
Depositor shall be required to deliver such Assignments for recording within 45
days of the Closing Date (or Subsequent Transfer Date, with respect to
Subsequent Mortgage Loans). The Depositor shall furnish the Trustee, or its
designated agent, with a copy of each Assignment submitted for recording. In the
event that any such Assignment is lost or returned unrecorded because of a
defect therein, the Depositor shall promptly have a substitute Assignment
prepared or have such defect cured, as the case may be, and thereafter cause
each such Assignment to be duly recorded. In the event that any Mortgage Note is
endorsed in blank as of the Closing Date (or Subsequent Transfer Date, with
respect to Subsequent Mortgage Loans), promptly following the Closing Date (or
Subsequent Transfer Date, with respect to Subsequent Mortgage Loans) the
Depositor shall cause to be completed such endorsements "Pay to the order of
Wells Fargo Bank Minnesota, N.A., as Trustee, without recourse."

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

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

                                       49

<PAGE>

for recordation, if known and (D) specify the date the applicable recorded
document is expected to be delivered to the Custodian, and, upon receipt of a
copy of such document certified by the public recording office, the Master
Servicer shall immediately deliver such document to the Custodian. In the event
the appropriate public recording office will not certify as to the accuracy of
such document, the Master Servicer shall deliver a copy of such document
certified by an officer of the Master Servicer to be a true and complete copy of
the original to the Custodian.

          SECTION 2.02. Acceptance by Trustee.

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

          The Trustee agrees, for the benefit of the Certificateholders, to
review, or that it has reviewed pursuant to Section 2.01 (or to cause the
Custodian to review or that it has caused the Custodian to have reviewed) each
Mortgage File on or prior to the Closing Date, with respect to each Initial
Mortgage Loan or the Subsequent Transfer Date, with respect to each Subsequent
Mortgage Loan (or, with respect to any document delivered after the Startup Day,
within 45 days of receipt and with respect to any Qualified Substitute Mortgage,
within 45 days after the assignment thereof). The Trustee further agrees, for
the benefit of the Certificateholders, to certify to the Depositor, the Master
Servicer and the NIMS Insurer in substantially the form attached hereto as
Exhibit F-1, within 45 days after the Closing Date, with respect to each Initial
Mortgage Loan and the Subsequent Transfer Date, with respect to each Subsequent
Mortgage Loan (or, with respect to any document delivered after the Startup Day,
within 45 days of receipt and with respect to any Qualified Substitute Mortgage,
within 45 days after the assignment thereof) that, as to each Mortgage Loan
listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full
or any Mortgage Loan specifically identified in the exception report annexed
thereto as not being covered by such certification), (i) all documents required
to be delivered to it pursuant Section 2.01 of this Agreement are in its
possession, (ii) such documents have been reviewed by it and have not been
mutilated, damaged or torn and relate to such Mortgage Loan and (iii) based on
its examination and only as to the foregoing, the information set forth in the
Mortgage Loan Schedule that corresponds to items (1) and (2) of the Mortgage
Loan Schedule accurately reflects information set forth in the Mortgage File. It
is herein acknowledged that, in conducting such review, the Trustee (or the
Custodian, as applicable) is under no duty or obligation to inspect, review or
examine any such documents, instruments, certificates or other papers to
determine that they are genuine, enforceable, or appropriate for the represented
purpose or that they have actually been recorded or that they are other than
what they purport to be on their face.

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

                                       50

<PAGE>

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

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

          SECTION 2.03.   Repurchase or Substitution of Mortgage Loans by the
                          Originator.

          (a) Upon discovery or receipt of written notice of any materially
defective document in, or that a document is missing from, a Mortgage File or of
the breach by the Originator of any representation, warranty or covenant under
the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which
materially adversely affects the value of such Mortgage Loan or the interest
therein of the Certificateholders, the Trustee shall promptly notify the
Originator, the NIMS Insurer and the Master Servicer of such defect, missing
document or breach and request that the Originator deliver such missing document
or cure such defect or breach within 90 days from the date the Originator was
notified of such missing document, defect or breach, and if the Originator does
not deliver such missing document or cure such defect or breach in all material
respects during such period, the Trustee shall enforce the Originator's
obligation under the Mortgage Loan Purchase Agreement and cause the Originator
to repurchase such Mortgage Loan from the Trust Fund at the Purchase Price on or
prior to the Determination Date following the expiration of such 90 day period
(subject to Section 2.03(e)); PROVIDED that, in connection with any such breach
that could not reasonably have been cured within such 90 day period, if the
Originator shall have commenced to cure such breach within such 90 day period,
the Originator shall be permitted to proceed thereafter diligently and
expeditiously to cure the same within the additional period provided under the
Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased
Mortgage Loan shall be deposited in the Collection Account, and the Trustee,
upon receipt of written certification from the Master Servicer of such deposit,
shall release to the Originator the related Mortgage File and shall execute and
deliver such instruments of transfer or assignment, in each case without
recourse,

                                       51

<PAGE>

as the Originator shall furnish to it and as shall be necessary to vest in the
Originator any Mortgage Loan released pursuant hereto and the Trustee shall have
no further responsibility with regard to such Mortgage File (it being understood
that the Trustee shall have no responsibility for determining the sufficiency of
such assignment for its intended purpose). In lieu of repurchasing any such
Mortgage Loan as provided above, the Originator may cause such Mortgage Loan to
be removed from the Trust Fund (in which case it shall become a Deleted Mortgage
Loan) and substitute one or more Qualified Substitute Mortgage Loans in the
manner and subject to the limitations set forth in Section 2.03(d). It is
understood and agreed that the obligation of the Originator to cure or to
repurchase (or to substitute for) any Mortgage Loan as to which a document is
missing, a material defect in a constituent document exists or as to which such
a breach has occurred and is continuing shall constitute the sole remedy against
the Originator respecting such omission, defect or breach available to the
Trustee on behalf of the Certificateholders.

          (b) Within 90 days of the earlier of discovery by the Depositor or
receipt of notice by the Depositor of the breach of any representation, warranty
or covenant of the Depositor set forth in Section 2.06 which materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the Depositor shall cure such breach in all material respects.

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

          (d) Any substitution of Qualified Substitute Mortgage Loans for
Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected prior
to the last Business Day that is within two years after the Closing Date. As to
any Deleted Mortgage Loan for which the Originator substitutes a Qualified
Substitute Mortgage Loan or Loans, such substitution shall be effected by the
Originator delivering to the Trustee, for such Qualified Substitute Mortgage
Loan or Loans, the Mortgage Note, the Mortgage and the Assignment to the
Trustee, and such other documents and agreements, with all necessary
endorsements thereon, as are required by Section 2.01, together with an
Officers' Certificate providing that each such Qualified Substitute Mortgage
Loan satisfies the definition thereof and specifying the Substitution Adjustment
(as described below), if any, in connection with such substitution. The Trustee
shall acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans
and, within ten Business Days thereafter, shall review such documents as
specified in Section 2.02 and deliver to the Master Servicer and the NIMS
Insurer, with respect to such Qualified Substitute Mortgage Loan or Loans, a
certification substantially in the form attached hereto as Exhibit F-1, with any
applicable exceptions noted thereon. Within one year of the date of
substitution, the Trustee shall deliver to the Master Servicer and the NIMS
Insurer a certification substantially in the form of Exhibit F-2 hereto with
respect to such Qualified Substitute Mortgage Loan or Loans, with any applicable
exceptions noted thereon. Monthly Payments due with respect to Qualified
Substitute Mortgage Loans in the month of substitution are not part of the Trust
Fund and will be retained by the Originator. For the month of substitution,
distributions to Certificateholders will reflect the collections and recoveries
in respect of such Deleted Mortgage Loan in the Due Period preceding the month
of substitution and the Originator shall thereafter be entitled to retain all
amounts subsequently received in respect of such Deleted Mortgage Loan. The

                                       52

<PAGE>

Originator shall give or cause to be given written notice to the
Certificateholders and the NIMS Insurer that such substitution has taken place,
shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted
Mortgage Loan from the terms of this Agreement and the substitution of the
Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of such
amended Mortgage Loan Schedule to the NIMS Insurer and the Trustee. Upon such
substitution by the Originator, such Qualified Substitute Mortgage Loan or Loans
shall constitute part of the Mortgage Pool and shall be subject in all respects
to the terms of this Agreement and the Mortgage Loan Purchase Agreement,
including all applicable representations and warranties thereof included in the
Mortgage Loan Purchase Agreement as of the date of substitution.

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

          In addition, the Originator shall obtain at its own expense and
deliver to the Trustee and the NIMS Insurer an Opinion of Counsel to the effect
that such substitution will not cause (a) any federal tax to be imposed on the
Trust Fund, including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(l) of the Code or on "contributions after
the startup date" under Section 860G(d)(l) of the Code or (b) any REMIC to fail
to qualify as a REMIC at any time that any Certificate is outstanding. If such
Opinion of Counsel can not be delivered, then such substitution may only be
effected at such time as the required Opinion of Counsel can be given.

          (e) Upon discovery by the Originator, the Master Servicer, the NIMS
Insurer or the Trustee that any Mortgage Loan does not constitute a "qualified
mortgage" within the meaning of Section 860G(a)(3) of the Code, the party
discovering such fact shall within two Business Days give written notice thereof
to the other parties. In connection therewith, the Originator or the Depositor,
as the case may be, shall repurchase or, subject to the limitations set forth in
Section 2.03(d), substitute one or more Qualified Substitute Mortgage Loans for
the affected Mortgage Loan within 90 days of the earlier of discovery or receipt
of such notice with respect to such affected Mortgage Loan. Such repurchase or
substitution shall be made (i) by the Originator if the affected Mortgage Loan's
status as a non-qualified mortgage is or results from a breach of any
representation, warranty or covenant made by the Originator under the Mortgage
Loan Purchase Agreement or (ii) the Depositor, if the affected Mortgage Loan's
status as a non-qualified mortgage is a breach of any representation or warranty
of the Depositor set forth in Section 2.06, or if its status as a non-qualified
mortgage is a breach of no representation or warranty. Any such repurchase or
substitution shall be

                                       53

<PAGE>

made in the same manner as set forth in Section 2.03(a), if made by the
Originator, or Section 2.03(b), if made by the Depositor. The Trustee shall
reconvey to the Depositor or the Originator, as the case may be, the Mortgage
Loan to be released pursuant hereto in the same manner, and on the same terms
and conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty.

          SECTION 2.04. Intentionally Omitted.

          SECTION 2.05. Representations, Warranties and Covenants of the Master
                        Servicer.

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

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

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

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

                                       54

<PAGE>

          (iv) This Agreement, and all documents and instruments contemplated
     hereby which are executed and delivered by the Master Servicer, constitute
     and will constitute valid, legal and binding obligations of the Master
     Servicer, enforceable in accordance with their respective terms, except as
     the enforcement thereof may be limited by applicable bankruptcy laws and
     general principles of equity;

          (v) [Reserved];

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

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

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

          (ix) The Master Servicer covenants that its computer and other systems
     used in servicing the Mortgage Loans operate in a manner such that the
     Master Servicer can service the Mortgage Loans in accordance with the terms
     of this Agreement;

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

          (xi) The Master Servicer will not waive any Prepayment Charge unless
     it is waived in accordance with the standard set forth in Section 3.01.

                                       55

<PAGE>

          It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.05 shall survive delivery of the Mortgage
Files to the Trustee and shall inure to the benefit of the Trustee, the
Depositor and the Certificateholders. Upon discovery by any of the Depositor,
the NIMS Insurer, the Master Servicer, the Originator or the Trustee of a breach
of any of the foregoing representations, warranties and covenants which
materially and adversely affects the value of any Mortgage Loan, Prepayment
Charge or the interests therein of the Certificateholders, the party discovering
such breach shall give prompt written notice (but in no event later than two
Business Days following such discovery) to the Master Servicer, the Originator,
the NIMS Insurer and the Trustee. Notwithstanding the foregoing, within 90 days
of the earlier of discovery by the Master Servicer or receipt of notice by the
Master Servicer of the breach of the representation or covenant of the Master
Servicer (in its capacity as Originator) set forth in Sections 2.05(x) or
2.05(xi) above which materially and adversely affects the interests of the
Holders of the Class P Certificates in any Prepayment Charge, the Master
Servicer shall remedy such breach as follows: (a) if the representation made by
the Master Servicer (in its capacity as Originator) in Section 2.05(x) above is
breached and a Principal Prepayment has occurred in the applicable Prepayment
Period or if a change of law subsequent to the Closing Date limits the
enforceability of a Prepayment Charge (other than in the circumstances provided
in Section 2.05(x) above), the Master Servicer (in its capacity as Originator)
must pay the amount of the scheduled Prepayment Charge, for the benefit of the
Holders of the Class P Certificates, by depositing such amount into the
Collection Account, net of any amount previously collected by the Master
Servicer and paid by the Master Servicer, for the benefit of the Holders of the
Class P Certificates, in respect of such Prepayment Charge; and (b) if any of
the covenants made by the Master Servicer in Section 2.05(xi) above is breached,
the Master Servicer must pay the amount of such waived Prepayment Charge, for
the benefit of the Holders of the Class P Certificates, by depositing such
amount into the Collection Account. The foregoing shall not, however, limit any
remedies available to the Certificateholders, the Depositor or the Trustee on
behalf of the Certificateholders, pursuant to the Mortgage Loan Purchase
Agreement signed by the Master Servicer in its capacity as Originator,
respecting a breach of the representations, warranties and covenants of the
Master Servicer in its capacity as Originator contained in the Mortgage Loan
Purchase Agreement.

          SECTION 2.06. Representations and Warranties of the Depositor.

          The Depositor represents and warrants to the Trust and the Trustee on
behalf of the Certificateholders as follows:

          (i) This Agreement constitutes a legal, valid and binding obligation
     of the Depositor, enforceable against the Depositor in accordance with its
     terms, except as enforceability may be limited by applicable bankruptcy,
     insolvency, reorganization, moratorium or other similar laws now or
     hereafter in effect affecting the enforcement of creditors' rights in
     general and except as such enforceability may be limited by general
     principles of equity (whether considered in a proceeding at law or in
     equity);

          (ii) Immediately prior to the sale and assignment by the Depositor to
     the Trustee on behalf of the Trust of each Mortgage Loan, the Depositor had
     good and marketable title to each Mortgage Loan (insofar as such title was
     conveyed to it by the Seller) subject to no

                                       56

<PAGE>

     prior lien, claim, participation interest, mortgage, security interest,
     pledge, charge or other encumbrance or other interest of any nature;

          (iii) As of the Closing Date, the Depositor has transferred all right,
     title and interest in the Mortgage Loans to the Trustee on behalf of the
     Trust;

          (iv) The Depositor has not transferred the Mortgage Loans to the
     Trustee on behalf of the Trust with any intent to hinder, delay or defraud
     any of its creditors;

          (v) The Depositor has been duly incorporated and is validly existing
     as a corporation in good standing under the laws of Delaware, with full
     corporate power and authority to own its assets and conduct its business as
     presently being conducted;

          (vi) The Depositor is not in violation of its articles of
     incorporation or by-laws or in default in the performance or observance of
     any material obligation, agreement, covenant or condition contained in any
     contract, indenture, mortgage, loan agreement, note, lease or other
     instrument to which the Depositor is a party or by which it or its
     properties may be bound, which default might result in any material adverse
     changes in the financial condition, earnings, affairs or business of the
     Depositor or which might materially and adversely affect the properties or
     assets, taken as a whole, of the Depositor;

          (vii) The execution, delivery and performance of this Agreement by the
     Depositor, and the consummation of the transactions contemplated thereby,
     do not and will not result in a material breach or violation of any of the
     terms or provisions of, or, to the knowledge of the Depositor, constitute a
     default under, any indenture, mortgage, deed of trust, loan agreement or
     other agreement or instrument to which the Depositor is a party or by which
     the Depositor is bound or to which any of the property or assets of the
     Depositor is subject, nor will such actions result in any violation of the
     provisions of the articles of incorporation or by-laws of the Depositor or,
     to the best of the Depositor's knowledge without independent investigation,
     any statute or any order, rule or regulation of any court or governmental
     agency or body having jurisdiction over the Depositor or any of its
     properties or assets (except for such conflicts, breaches, violations and
     defaults as would not have a material adverse effect on the ability of the
     Depositor to perform its obligations under this Agreement);

          (viii) To the best of the Depositor's knowledge without any
     independent investigation, no consent, approval, authorization, order,
     registration or qualification of or with any court or governmental agency
     or body of the United States or any other jurisdiction is required for the
     issuance of the Certificates, or the consummation by the Depositor of the
     other transactions contemplated by this Agreement, except such consents,
     approvals, authorizations, registrations or qualifications as (a) may be
     required under State securities or Blue Sky laws, (b) have been previously
     obtained or (c) the failure of which to obtain would not have a material
     adverse effect on the performance by the Depositor of its obligations
     under, or the validity or enforceability of, this Agreement; and

          (ix) There are no actions, proceedings or investigations pending
     before or, to the Depositor's knowledge, threatened by any court,
     administrative agency or other tribunal to

                                       57

<PAGE>

     which the Depositor is a party or of which any of its properties is the
     subject: (a) which if determined adversely to the Depositor would have a
     material adverse effect on the business, results of operations or financial
     condition of the Depositor; (b) asserting the invalidity of this Agreement
     or the Certificates; (c) seeking to prevent the issuance of the
     Certificates or the consummation by the Depositor of any of the
     transactions contemplated by this Agreement, as the case may be; or (d)
     which might materially and adversely affect the performance by the
     Depositor of its obligations under, or the validity or enforceability of,
     this Agreement.

          SECTION 2.07. Issuance of Certificates.

          The Trustee acknowledges the assignment to it of the Mortgage Loans
and the delivery to it of the Mortgage Files, subject to the provisions of
Sections 2.01 and 2.02, together with the assignment to it of all other assets
included in the Trust Fund, receipt of which is hereby acknowledged.
Concurrently with such assignment and delivery and in exchange therefor, the
Trustee, pursuant to the written request of the Depositor executed by an officer
of the Depositor, has executed, authenticated and delivered to or upon the order
of the Depositor, the Certificates in authorized denominations. The interests
evidenced by the Certificates, constitute the entire beneficial ownership
interest in the Trust Fund.

          SECTION 2.08. Conveyance of the Subsequent Mortgage Loans.

          (a) Subject to the conditions set forth in paragraph (b) below in
consideration of the Trustee's delivery on the Subsequent Transfer Dates to or
upon the order of the Depositor of all or a portion of the balance of funds in
the Pre-Funding Account, the Depositor shall on any Subsequent Transfer Date
sell, transfer, assign, set over and convey without recourse to the Trust Fund
but subject to the other terms and provisions of this Agreement all of the
right, title and interest of the Depositor in and to (i) the Subsequent Mortgage
Loans identified on the Mortgage Loan Schedule attached to the related
Subsequent Transfer Instrument delivered by the Depositor on such Subsequent
Transfer Date, (ii) all interest accruing thereon on and after the Subsequent
Cut-off Date and all collections in respect of interest and principal due after

the related Mortgage Files; PROVIDED, HOWEVER, that the Depositor reserves and
retains all right, title and interest in and to principal received and interest
accruing on the Subsequent Mortgage Loans prior to the related Subsequent
Cut-off Date. The transfer to the Trustee for deposit in the Mortgage Pool by
the Depositor of the Subsequent Mortgage Loans identified on the Mortgage Loan
Schedule shall be absolute and is intended by the Depositor, the Master
Servicer, the Trustee and the Certificateholders to constitute and to be treated
as a sale of the Subsequent Mortgage Loans by the Depositor to the Trust Fund.
The related Mortgage File for each Subsequent Mortgage Loan shall be delivered
to the Trustee at least three Business Days prior to the related Subsequent
Transfer Date.

          The purchase price paid by the Trustee from amounts released from the
Pre-Funding Account shall be one-hundred percent (100%) of the aggregate Stated
Principal Balance of the Subsequent Mortgage Loans so transferred (as identified
on the Mortgage Loan Schedule provided

                                       58

related thereto as described in paragraph (a) above, and the Trustee shall
release funds from the Pre-Funding Account, only upon the satisfaction of each
of the following conditions on or prior to the related Subsequent Transfer Date:

          (i) the Depositor shall have provided the Trustee, the NIMS Insurer
     and the Rating Agencies with a timely Addition Notice and shall have

     Master Servicer, in its capacity as Originator, shall have delivered a
     computer file containing such Mortgage Loan Schedule to the Trustee at
     least three Business Days prior to the related Subsequent Transfer Date;

          (iii) as of each Subsequent Transfer Date, as evidenced by delivery of

     for the benefit of the Certificateholders all the right, title and interest
     of the Depositor, in, to and under the Subsequent Mortgage Loan Purchase
     Agreement, to the extent of the Subsequent Mortgage Loans;

          (viii) with respect to the last Subsequent Transfer Date, the
     Depositor shall have delivered to the Trustee and the NIMS Insurer a letter
     from an Independent accountant (with copies provided to each Rating Agency)

     to the characteristics set forth in paragraphs (c) and (d) below;

          (ix) the Depositor shall have delivered to the Trustee and the NIMS
     Insurer an Opinion of Counsel addressed to the Trustee and the Rating
     Agencies with respect to the

     transfer of the Subsequent Mortgage Loans substantially in the form of the
     Opinion of Counsel delivered to the Trustee on the Closing Date regarding
     the true sale of the Subsequent Mortgage Loans; and

          (x) the Depositor shall have received the consent of the NIMS Insurer

          (e) Notwithstanding the foregoing, any Subsequent Mortgage Loan may be
rejected by (i) the NIMS Insurer or (ii) either Rating Agency if the inclusion
of any such Subsequent Mortgage Loan would adversely affect the ratings of any
Class of Certificates. At least one Business Day prior to the Subsequent
Transfer Date, each Rating Agency shall notify the Trustee as to which
Subsequent Mortgage Loans, if any, shall not be included in the transfer on the
Subsequent Transfer Date; provided, however, that the Master Servicer, in its

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

          SECTION 3.01. Master Servicer to Act as Master Servicer.

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

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

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

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

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

          To the extent consistent with the foregoing, the Master Servicer (a)
shall seek the timely and complete recovery of principal and interest on the
Mortgage Notes and (b) shall waive (or permit a Sub-Servicer to waive) a
Prepayment Charge only under the following circumstances: (i) such waiver is
standard and customary in servicing similar Mortgage Loans and (ii) either (A)
such waiver relates to a default or a reasonably foreseeable default and would,
in the reasonable judgement of the Master Servicer, maximize recovery of total
proceeds taking into account the value of such Prepayment Charge and the related
Mortgage Loan or (B) such waiver is made in connection with a refinancing of the
related Mortgage Loan unrelated to a default or a reasonably foreseeable default
where (x) the related mortgagor has stated to the Master Servicer or an
applicable Sub- Servicer an intention to refinance the related Mortgage Loan and
(y) the Master Servicer has concluded in its reasonable judgement that the
waiver of such Prepayment Charge would induce such mortgagor to refinance with
the Master Servicer; provided, however, that the Master Servicer shall waive no
more than 5.00% of the Prepayment Charges (by number of Prepayment Charges) set
forth on the Prepayment Charge Schedule in accordance with clause (ii)(B) above.
If a Prepayment Charge is waived as permitted by meeting the standards described
in clauses (i) and (ii)(B) above, then the Master Servicer is required to pay
the amount of such waived Prepayment Charge, for the benefit of the Holders of
the Class P Certificates, by depositing such amount into the Collection Account
together with and at the time that the amount prepaid on the related Mortgage
Loan is required to be deposited into the Collection Account. Notwithstanding
any other provisions of this

                                       63

<PAGE>

Agreement, any payments made by the Master Servicer in respect of any waived
Prepayment Charges pursuant to clauses (i) and (ii)(B) above shall be deemed to
be paid outside of the Trust Fund. Subject only to the above-described servicing
standards and the terms of this Agreement and of the Mortgage Loans, the Master
Servicer shall have full power and authority, acting alone or through
Sub-Servicers as provided in Section 3.02, to do or cause to be done any and all
things in connection with such servicing and administration which it may deem
necessary or desirable. Without limiting the generality of the foregoing, the
Master Servicer in its own name or in the name of a Sub-Servicer is hereby
authorized and empowered by the Trustee when the Master Servicer believes it
appropriate in its best judgment in accordance with the servicing standards set
forth above, to execute and deliver, on behalf of the Certificateholders and the
Trustee, and upon notice to the Trustee, any and all instruments of satisfaction
or cancellation, or of partial or full release or discharge, and all other
comparable instruments, with respect to the Mortgage Loans and the Mortgaged
Properties and to institute foreclosure proceedings or obtain a deed-in-lieu of
foreclosure so as to convert the ownership of such properties, and to hold or
cause to be held title to such properties, on behalf of the Trustee and
Certificateholders. The Master Servicer shall service and administer the
Mortgage Loans in accordance with applicable state and federal law and shall
provide to the Mortgagors any reports required to be provided to them thereby.
The Master Servicer shall also comply in the performance of this Agreement with
all reasonable rules and requirements of each insurer under any standard hazard
insurance policy. Subject to Section 3.17, within 15 days of the Closing Date,
the Trustee shall execute, at the written request of the Master Servicer, and
furnish to the Master Servicer and any Sub-Servicer any special or limited
powers of attorney for each county in which a Mortgaged Property is located and
other documents necessary or appropriate to enable the Master Servicer or any
Sub-Servicer to carry out their servicing and administrative duties hereunder;
PROVIDED, such limited powers of attorney or other documents shall be prepared
by the Master Servicer and submitted to the Trustee for execution. The Trustee
shall not be liable for the actions of the Master Servicer or any Sub-Servicers
under such powers of attorney.

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

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

                                       64

<PAGE>

regulations promulgated thereunder) and (B) cause any REMIC created hereunder to
fail to qualify as a REMIC under the Code or the imposition of any tax on
"prohibited transactions" or "contributions after the startup date" under the
REMIC Provisions.

          SECTION 3.02. Sub-Servicing Agreements Between Master Servicer and
                        Sub- Servicers.

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

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

          (b) As part of its servicing activities hereunder, the Master
Servicer, for the benefit of the Trustee and the Certificateholders, shall
enforce the obligations of each Sub-Servicer under the related Sub-Servicing
Agreement and of the Originator under the Mortgage Loan Purchase

                                       65

<PAGE>

Agreement, including, without limitation, any obligation to make advances in
respect of delinquent payments as required by a Sub-Servicing Agreement, or to
purchase a Mortgage Loan on account of missing or defective documentation or on
account of a breach of a representation, warranty or covenant, as described in
Section 2.03(a). Such enforcement, including, without limitation, the legal
prosecution of claims, termination of Sub-Servicing Agreements, and the pursuit
of other appropriate remedies, shall be in such form and carried out to such an
extent and at such time as the Master Servicer, in its good faith business
judgment, would require were it the owner of the related Mortgage Loans. The
Master Servicer shall pay the costs of such enforcement at its own expense, and
shall be reimbursed therefor only (i) from a general recovery resulting from
such enforcement, to the extent, if any, that such recovery exceeds all amounts
due in respect of the related Mortgage Loans, or (ii) from a specific recovery
of costs, expenses or attorneys' fees against the party against whom such
enforcement is directed. Enforcement of the Mortgage Loan Purchase Agreement
against the Originator shall be effected by the Master Servicer to the extent it
is not the Originator, and otherwise by the Trustee in accordance with the
foregoing provisions of this paragraph.

          SECTION 3.03. Successor Sub-Servicers.

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

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

          SECTION 3.04. Liability of the Master Servicer.

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

                                       66

          SECTION 3.05. No Contractual Relationship Between Sub-Servicers and
                        the NIMS Insurer, the Trustee or Certificateholders.

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

          SECTION 3.06. Assumption or Termination of Sub-Servicing Agreements by
                        Trustee.

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

          The Master Servicer at its expense shall, upon request of Trustee,
deliver to the assuming party all documents and records relating to each
Sub-Servicing Agreement and the Mortgage Loans then being serviced and an
accounting of amounts collected and held by or on behalf of it, and otherwise
use its best efforts to effect the orderly and efficient transfer of the Sub-
Servicing Agreements to the assuming party. All Servicing Transfer Costs shall
be paid by the predecessor Master Servicer upon presentation of reasonable
documentation of such costs, and if such predecessor Master Servicer defaults in
its obligation to pay such costs, such costs shall be paid by the successor
Master Servicer or the Trustee (in which case the successor Master Servicer or
the Trustee, as applicable, shall be entitled to reimbursement therefor from the
assets of the Trust).

          SECTION 3.07. Collection of Certain Mortgage Loan Payments.

          The Master Servicer shall make reasonable efforts to collect all
payments called for under the terms and provisions of the Mortgage Loans, and
shall, to the extent such procedures shall be consistent with this Agreement and
the terms and provisions of any applicable insurance policies, follow such
collection procedures as it would follow with respect to mortgage loans
comparable to

                                       67

<PAGE>

the Mortgage Loans and held for its own account. Consistent with the foregoing,
the Master Servicer may in its discretion (i) waive any late payment charge or,
if applicable, any penalty interest, or (ii) extend the due dates for the
Monthly Payments due on a Mortgage Note for a period of not greater than 180
days; PROVIDED, HOWEVER, that any extension pursuant to clause (ii) above shall
not affect the amortization schedule of any Mortgage Loan for purposes of any
computation hereunder, except as provided below; provided further that the NIMS
Insurer's prior written consent shall be required for any modification, waiver
or amendment if the amendment if the aggregate number of outstanding Mortgage
Loans which have been modified, waived or amended exceeds 5% of the number of
Mortgage Loans as of the Cut-off Date and any Subsequent Cut-off Date. In the
event of any such arrangement pursuant to clause (ii) above, the Master Servicer
shall make timely advances on such Mortgage Loan during such extension pursuant
to Section 4.04 and in accordance with the amortization schedule of such
Mortgage Loan without modification thereof by reason of such arrangement.
Notwithstanding the foregoing, in the event that any Mortgage Loan is in default
or, in the judgment of the Master Servicer, such default is reasonably
foreseeable, the Master Servicer, consistent with the standards set forth in
Section 3.01, may also waive, modify or vary any term of such Mortgage Loan
(including modifications that would change the Mortgage Rate, forgive the
payment of principal or interest or extend the final maturity date of such
Mortgage Loan), accept payment from the related Mortgagor of an amount less than
the Stated Principal Balance in final satisfaction of such Mortgage Loan, or
consent to the postponement of strict compliance with any such term or otherwise
grant indulgence to any Mortgagor (any and all such waivers, modifications,
variances, forgiveness of principal or interest, postponements, or indulgences
collectively referred to herein as "forbearance"), PROVIDED, HOWEVER, that in no
event shall the Master Servicer grant any such forbearance (other than as
permitted by the second sentence of this Section) with respect to any one
Mortgage Loan more than once in any 12 month period or more than three times
over the life of such Mortgage Loan, and PROVIDED, FURTHER, that in determining
which course of action permitted by this sentence it shall pursue, the Master
Servicer shall adhere to the Loss Mitigation Procedures. The Master Servicer's
analysis supporting any forbearance and the conclusion that any forbearance
meets the standards of Section 3.01 and the Loss Mitigation Procedures shall be
reflected in writing in the Mortgage File.

          SECTION 3.08. Sub-Servicing Accounts.

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

                                       68

<PAGE>

Agreement, the Master Servicer shall be deemed to have received payments on the
Mortgage Loans when the Sub-Servicer receives such payments.

          SECTION 3.09. Collection of Taxes, Assessments and Similar Items;
                        Servicing Accounts.

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

          SECTION 3.10. Collection Account, Initial Deposit Account and
                        Distribution Account.

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

          (i) all payments on account of principal, including Principal
     Prepayments (but not Prepayment Charges), on the Mortgage Loans;

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

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

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

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

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

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

          (viii) all Prepayment Charges collected by the Master Servicer and any
     Master Servicer Prepayment Charge Payment Amounts in connection with the
     Principal Prepayment of any of the Mortgage Loans; and

                                       70

<PAGE>

          (ix) without duplication, all payments of claims under the PMI Policy.

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

          (b) On behalf of the Trust Fund, the Trustee shall establish and
maintain one or more accounts (such account or accounts, the "Distribution
Account"), held in trust for the benefit of the Trustee and the
Certificateholders. On behalf of the Trust Fund, the Master Servicer shall
deliver to the Trustee in immediately available funds for deposit in the
Distribution Account on or before 3:00 p.m. New York time (i) on the Master
Servicer Remittance Date, that portion of the Available Funds (calculated
without regard to the references in the definition thereof to amounts that may
be withdrawn from the Distribution Account) for the related Distribution Date
then on deposit in the Collection Account, the amount of all Prepayment Charges
collected during the applicable Prepayment Period by the Master Servicer and
Master Servicer Prepayment Charge Payment Amounts in connection with the
Principal Prepayment of any of the Mortgage Loans then on deposit in the
Collection Account and the amount of any funds reimbursable to an Advancing
Person pursuant to Section 3.29, and (ii) on each Business Day as of the
commencement of which the balance on deposit in the Collection Account exceeds
$75,000 following any withdrawals pursuant to the next succeeding sentence, the
amount of such excess, but only if the Collection Account constitutes an
Eligible Account solely pursuant to clause (ii) of the definition of "Eligible
Account." If the balance on deposit in the Collection Account exceeds $75,000 as
of the commencement of business on any Business Day and the Collection Account
constitutes an Eligible Account solely pursuant to clause (ii) of the definition
of "Eligible Account," the Master Servicer shall, on or before 3:00 p.m. New
York time on such Business Day, withdraw from the Collection Account any and all
amounts payable or reimbursable to the Master Servicer, the Trustee, the
Originator or any Sub- Servicer pursuant to Section 3.11 and shall pay such
amounts to the Persons entitled thereto.

          On behalf of the Trust Fund, the Trustee shall establish and maintain
the Initial Deposit Account, held in trust for the benefit of
Certificateholders. On the Closing Date, the Depositor shall remit or cause to
be remitted to the Trustee, for deposit in the Initial Deposit Account, and the
Trustee shall deposit the Initial Deposit, to the extent received by it, into
the Initial Deposit Account. The Initial Deposit Account shall be treated as an
"outside reserve fund" under applicable Treasury regulations and shall not be
part of any REMIC. Any investment earnings on funds in the Initial Deposit
Account shall be treated as owned by the Depositor and will be taxable to the
Depositor. The Trustee shall be required to withdraw such earnings from the
Initial Deposit Account and remit the same to the Depositor on the first
Distribution Date (or as soon as received if such funds are not available on
such Distribution Date), and shall thereupon terminate such account.

                                       71

<PAGE>

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

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

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

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

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

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

          (v) any amounts required to be paid to the Trustee pursuant to the
          Agreement, including, but not limited to Section 3.06 and Section
          7.02.

          (e) [Reserved].

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

          SECTION 3.11. Withdrawals from the Collection Account and Distribution
                        Account.

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

          (ii) subject to Section 3.16(d), to reimburse the Master Servicer for
     (a) any unreimbursed Advances to the extent of amounts received which
     represent Late Collections (net of the related Servicing Fees) of Monthly
     Payments, Liquidation Proceeds and Insurance Proceeds on Mortgage Loans
     with respect to which such Advances were made in accordance with the
     provisions of Section 4.04; (b) any unreimbursed Advances with respect to
     the final liquidation of a Mortgage Loan that are Nonrecoverable Advances,
     but only to the extent that Late Collections, Liquidation Proceeds and
     Insurance Proceeds received with respect to such Mortgage Loan are
     insufficient to reimburse the Master Servicer for such unreimbursed
     Advances; or (c) subject to Section 4.04(b), any unreimbursed Advances to
     the extent of funds held in the Collection Account for future distribution
     that were not included in Available Funds for the preceding Distribution
     Date;

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

     Mortgage Loan are insufficient to reimburse the Master Servicer or any
     Sub-Servicer for Servicing Advances;

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

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

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

     Advances in respect of, expenses incurred in connection with any Mortgage

                                       73

<PAGE>

          (ix) to reimburse the NIMS Insurer, the Master Servicer (if the Master
     Servicer is not an Affiliate of the Originator) or the Trustee, as the case
     may be, for enforcement expenses reasonably incurred in respect of the
     breach or defect giving rise to the purchase obligation under Section 2.03
     of this Agreement that were included in the Purchase Price of the Mortgage
     Loan, including any expenses arising out of the enforcement of the purchase
     obligation;

          (ix) to pay itself any Prepayment Interest Excess; and

          (x) to clear and terminate the Collection Account pursuant to Section

shall be exclusive. In the event the Master Servicer shall deposit in the
Collection Account any amount not required to be deposited therein, it may at
any time withdraw such amount from the Collection Account, any provision herein
to the contrary notwithstanding.

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

                        Distribution Account.

          (a) The Master Servicer may direct any depository institution
maintaining the Interest Coverage Account and the Collection Account and at the
direction of the Master Servicer the Trustee shall direct any depository
institution maintaining the Distribution Account and the Initial Deposit Account

to invest the funds in such Investment Account in one or more Permitted
Investments bearing interest or sold at a discount, and maturing, unless payable
on demand, (i) no later than the Business Day immediately preceding the date on
which such funds are required to be withdrawn from such account pursuant to this
Agreement, if a Person other than the Trustee is the obligor thereon or if such
investment is managed or advised by a Person other than the Trustee or an
Affiliate of the Trustee, and (ii) no later than the date on which such funds
are required to be withdrawn from such account pursuant to this Agreement, if
the Trustee is the obligor thereon or if such investment is managed or advised
by the Trustee or any Affiliate. All such Permitted Investments shall be held to
maturity, unless payable on demand. Any investment of funds in an Investment
Account shall be made in the name of the Trustee (in its capacity as such), or
in the name of a nominee of the Trustee. The Trustee shall be entitled to sole
possession (except with respect to investment direction of funds held in the
Interest Coverage Account, the Initial Deposit Account and the Collection
Account and any income and gain realized thereon) over each such investment, and
any certificate or other instrument evidencing any such investment shall be
delivered directly to the Trustee or its agent, together with any document of
transfer necessary to transfer title to such investment to the Trustee or its
nominee. In the event amounts on deposit in an Investment Account are at any
time invested in a Permitted Investment payable on demand, the Trustee shall:

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

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

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

                                       75

<PAGE>

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

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

          SECTION 3.13. [Reserved].

          SECTION 3.14. Maintenance of Hazard Insurance and Errors and Omissions
                        and Fidelity Coverage.

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

                                       76

<PAGE>

additional insurance. If the Mortgaged Property or REO Property is at any time
in an area identified in the Federal Register by the Federal Emergency
Management Agency as having special flood hazards and flood insurance has been
made available, the Master Servicer will cause to be maintained a flood
insurance policy in respect thereof. Such flood insurance shall be in an amount
equal to the lesser of (i) the unpaid Principal Balance of the related Mortgage
Loan and (ii) the maximum amount of such insurance available for the related
Mortgaged Property under the national flood insurance program (assuming that the
area in which such Mortgaged Property is located is participating in such
program).

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

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

          SECTION 3.15. Enforcement of Due-On-Sale Clauses; Assumption
                        Agreements.

          The Master Servicer will, to the extent it has knowledge of any
conveyance or prospective conveyance of any Mortgaged Property by any Mortgagor
(whether by absolute conveyance or by contract of sale, and whether or not the
Mortgagor remains or is to remain liable

                                       77

<PAGE>

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

          The Master Servicer shall be entitled to any Prepayment Interest
Excess which it may withdraw from the Collection Account pursuant to Section
3.11(a).

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

          SECTION 3.16. Realization Upon Defaulted Mortgage Loans.

          (a) The Master Servicer shall use its best efforts, in as practical a
time frame as possible and consistent with Servicing Standard, to foreclose upon
or otherwise comparably convert

                                       78

<PAGE>

the ownership of properties securing such of the Mortgage Loans (including, if
such is the action to be taken that results from adherence to the Loss
Mitigation Procedures, selling any such Mortgage Loans other than converting the
ownership of the related properties as provided in Section 3.16(e) below) as
come into and continue in default and as to which no satisfactory arrangements
can be made for collection of delinquent payments pursuant to Section 3.07. The
Master Servicer shall be responsible for all costs and expenses incurred by it
in any such proceedings; PROVIDED, HOWEVER, that such costs and expenses will be
recoverable as Servicing Advances by the Master Servicer as contemplated in
Section 3.11 and Section 3.23. The foregoing is subject to the provision that,
in any case in which a Mortgaged Property shall have suffered damage from an
Uninsured Cause, the Master Servicer shall not be required to expend its own
funds toward the restoration of such property unless it shall determine in its
discretion that such restoration will increase the proceeds of liquidation of
the related Mortgage Loan after reimbursement to itself for such expenses.

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

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

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

          Notwithstanding the foregoing, if such environmental audit reveals, or
if the Master Servicer has actual knowledge or notice, that such Mortgaged
Property contains such wastes or substances, the Master Servicer shall not
foreclose or accept a deed in lieu of foreclosure without the prior written
consent of the NIMS Insurer.

          The cost of the environmental audit report contemplated by this
Section 3.16 shall be advanced by the Master Servicer, subject to the Master
Servicer's right to be reimbursed therefor from the Collection Account as
provided in Section 3.11(a)(vii), such right of reimbursement being

                                       79

<PAGE>

prior to the rights of Certificateholders to receive any amount in the
Collection Account received in respect of the affected Mortgage Loan or other
Mortgage Loans.

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

          (c)  (i) The NIMS Insurer may, at its option, purchase a Mortgage Loan
which has become 90 or more days delinquent or for which the Master Servicer has
accepted a deed in lieu of foreclosure. Prior to purchase pursuant to this
Section 3.16(c)(i), the Master Servicer shall be required to continue to make
Advances pursuant to Section 4.04. The NIMS Insurer shall not use any procedure
in selecting Mortgage Loans to be repurchased which is materially adverse to the
interests of the Certificateholders. The NIMS Insurer shall purchase such
delinquent Mortgage Loan at a price equal to the Purchase Price of such Mortgage
Loan. Any such purchase of a Mortgage Loan pursuant to this Section 3.16(c)(i)
shall be accomplished by remittance to the Master Servicer for deposit in the
Collection Account of the amount of the Purchase Price. The Trustee shall
immediately effectuate the conveyance of such delinquent Mortgage Loan to the
NIMS Insurer to the extent necessary, including the prompt delivery of all
documentation to the NIMS Insurer.

               (ii) If the Master Servicer Optional Purchase Delinquency Trigger
has been met, the Master Servicer may, at its option, purchase a Mortgage Loan
which has become 90 or more days delinquent or for which the Master Servicer has
accepted a deed in lieu of foreclosure. Prior to purchase pursuant to this
Section 3.16(c)(ii), the Master Servicer shall be required to continue to make
Advances pursuant to Section 4.04. The Master Servicer shall purchase such
delinquent Mortgage Loan at a price equal to the Purchase Price of such Mortgage
Loan. Any such purchase of a Mortgage Loan pursuant to this Section 3.16(c)(ii)
shall be accomplished by deposit in the Collection Account of the amount of the
Purchase Price. The Trustee shall immediately effectuate the conveyance of such
delinquent Mortgage Loan to the Master Servicer to the extent necessary,
including the prompt delivery of all documentation to the Master Servicer.

          Notwithstanding the foregoing: (A) the Master Servicer shall have the
option to purchase pursuant to this Section 3.16(c)(ii) only such delinquent
Mortgage Loans having an aggregate Principal Balance such that, if such
delinquent Mortgage Loans were not in the Trust, the Master Servicer Optional
Purchase Delinquency Trigger would not be met; (B) if the Master Servicer
purchases any delinquent Mortgage Loans pursuant to this Section 3.16(c)(ii), it
must purchase Mortgage Loans that are delinquent the greatest number of days
before it may purchase any that are

                                       80

<PAGE>

delinquent any fewer number of days; (C) if the Master Servicer purchases some
but not all Mortgage Loans that are delinquent any given number of days, it must
purchase Mortgage Loans having the same delinquency status in the order of
lowest Principal Balance to highest Principal Balance; (D) the Master Servicer
may at any time relinquish its rights to purchase delinquent Mortgage Loans
pursuant to this Section 3.16(C)(ii) in writing delivered to the Trustee, and
from and after the taking of such action by the Master Servicer, the provisions
of this Section 3.16(c)(ii) shall no longer be of any force or effect.

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

          SECTION 3.17. Trustee to Cooperate; Release of Mortgage Files.

          (a) Upon the payment in full of any Mortgage Loan, or the receipt by
the Master Servicer of a notification that payment in full shall be escrowed in
a manner customary for such purposes, the Master Servicer shall deliver to the
Trustee, in written (with two executed copies) or electronic format, a Request
for Release in the form of Exhibit E (which certification shall include a
statement to the effect that all amounts received or to be received in
connection with such payment which are required to be deposited in the
Collection Account pursuant to Section 3.10 have been or will be so deposited)
signed by a Servicing Officer (or in a mutually agreeable electronic format that
will, in lieu of a signature on its face, originate from a Servicing Officer)
and shall request delivery to it of the Mortgage File. Upon receipt of such
certification and request, the Trustee shall, within three Business Days,
release and send by overnight mail, at the expense of the Master Servicer, the
related Mortgage File to the Master Servicer. The Trustee agrees to indemnify
the Master Servicer, out of its own funds, for any loss, liability or expense
(other than special, indirect, punitive or consequential damages which will not
be paid by the Trustee) incurred by the Master Servicer as a proximate result of
the Trustee's breach of its obligations pursuant to this Section 3.17. No
expenses incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Collection Account or the Distribution
Account.

          (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any insurance policy relating to the Mortgage Loans, the Trustee shall, upon any
request made by or on behalf of the Master Servicer and delivery to the Trustee,
in written (with two executed copies) or electronic format, of a Request for
Release in the form of Exhibit E signed by a Servicing Officer (or in a mutually
agreeable electronic format that will, in lieu of a signature on its face,
originate from a Servicing Officer), release the related Mortgage File to the
Master Servicer within three Business Days, and the Trustee

                                       81

<PAGE>

shall, at the direction of the Master Servicer, execute such documents as shall
be necessary to the prosecution of any such proceedings. Such Request for
Release shall obligate the Master Servicer to return each and every document
previously requested from the Mortgage File to the Trustee when the need
therefor by the Master Servicer no longer exists, unless the Mortgage Loan has
been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have
been deposited in the Collection Account or the Mortgage File or such document
has been delivered to an attorney, or to a public trustee or other public
official as required by law, for purposes of initiating or pursuing legal action
or other proceedings for the foreclosure of the Mortgaged Property either
judicially or non- judicially, and the Master Servicer has delivered, or caused
to be delivered, to the Trustee an additional Request for Release certifying as
to such liquidation or action or proceedings. Upon the request of the Trustee,
the Master Servicer shall provide notice to the Trustee of the name and address
of the Person to which such Mortgage File or such document was delivered and the
purpose or purposes of such delivery. Upon receipt of a Request for Release, in
written (with two executed copies) or electronic format, from a Servicing
Officer stating that such Mortgage Loan was liquidated and that all amounts
received or to be received in connection with such liquidation that are required
to be deposited into the Collection Account have been so deposited, or that such
Mortgage Loan has become an REO Property, such Mortgage Loan shall be released
by the Trustee to the Master Servicer or its designee.

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

          SECTION 3.18. Servicing Compensation.

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

                                       82

<PAGE>

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

          The Master Servicer shall be entitled to any Prepayment Interest
Excess, which it may withdraw from the Collection Account pursuant to Section
3.11(a)(ix).

          SECTION 3.19. Reports to the Trustee; Collection Account Statements.

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

          SECTION 3.20. Statement as to Compliance.

          The Master Servicer will deliver to the Trustee, the NIMS Insurer and
the Depositor not later than 90 days following the end of the fiscal year of the
Master Servicer (which, as of the Closing Date, ends on the last day of April),
commencing in 2002, an Officers' Certificate stating, as to each signatory
thereof, that (i) a review of the activities of the Master Servicer during the
preceding year and of performance under this Agreement has been made under such
officers' supervision and (ii) to the best of such officers' knowledge, based on
such review, the Master Servicer has fulfilled all of its obligations under this
Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officer and the nature and status thereof. Copies of any such statement shall be
provided by the Trustee to any Certificateholder and to any Person identified to
the Trustee as a prospective transferee of a Certificate, upon request at the
expense of the requesting party, provided such statement is delivered by the
Master Servicer to the Trustee.

          SECTION 3.21. Independent Public Accountants' Servicing Report.

          Not later than 90 days following the end of each fiscal year of the
Master Servicer, commencing in 2002, the Master Servicer, at its expense, shall
cause a nationally recognized firm of independent certified public accountants
to furnish to the Master Servicer a report stating that (i) it has obtained a
letter of representation regarding certain matters from the management of the
Master Servicer which includes an assertion that the Master Servicer has
complied with certain

                                       83

<PAGE>

minimum residential mortgage loan servicing standards, identified in the Uniform
Single Attestation Program for Mortgage Bankers established by the Mortgage
Bankers Association of America, with respect to the servicing of residential
mortgage loans during the most recently completed fiscal year and (ii) on the
basis of an examination conducted by such firm in accordance with standards
established by the American Institute of Certified Public Accountants, such
representation is fairly stated in all material respects, subject to such
exceptions and other qualifications that may be appropriate. In rendering its
report such firm may rely, as to matters relating to the direct servicing of
residential mortgage loans by Sub-Servicers, upon comparable reports of firms of
independent certified public accountants rendered on the basis of examinations
conducted in accordance with the same standards (rendered within one year of
such report) with respect to those Sub-Servicers. Immediately upon receipt of
such report, the Master Servicer shall furnish a copy of such report to the
Trustee, the NIMS Insurer and 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 that such statement is delivered by the Master
Servicer to the Trustee.

          SECTION 3.22. Access to Certain Documentation; Filing of Reports by
                        Trustee.

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

          (b) Within 15 days after each Distribution Date, the Trustee shall
file with the Securities and Exchange Commission via the Electronic Data
Gathering Analysis and Retrieval System (EDGAR), a Form 8-K with a copy of the
statement to Certificateholders for such Distribution Date as an exhibit
thereto. Prior to January 30, 2002, the Trustee shall file a Form 15 Suspension
Notification with respect to the Trust Fund, if applicable. Prior to March 30,
2002, the Trustee shall file a Form 10-K, in substance conforming to industry
standards, with respect to the Trust Fund. The Depositor hereby grants to the
Trustee a limited power of attorney to execute and file each such document on
behalf of the Depositor. Such power of attorney shall continue until the earlier
of (i) receipt by the Trustee from the Depositor of written termination of such
power of attorney and (ii) the termination of the Trust Fund. The Depositor
agrees to promptly furnish to the Trustee, from time to time upon request, such
further information, reports and financial statements within its control related
to this Agreement and the Mortgage Loans as the Trustee reasonably deems
appropriate to prepare and file all necessary reports with the Securities and
Exchange Commission. The Trustee shall have no responsibility to file any items
with the Securities and Exchange Commission other than those specified in this
Section.

          SECTION 3.23. Title, Management and Disposition of REO Property.

                                       84

<PAGE>

          (a) The deed or certificate of sale of any REO Property shall be taken
in the name of the Trustee, or its nominee, in trust for the benefit of the
Certificateholders. The Master Servicer, on behalf of REMIC 1, shall sell any
REO Property as soon as practical and in any event no later than the end of the
third full taxable year after the taxable year in which such REMIC acquires
ownership of such REO Property for purposes of Section 860G(a)(8) of the Code or
request from the Internal Revenue Service, no later than 60 days before the day
on which the three-year grace period would otherwise expire, an extension of
such three-year period, unless the Master Servicer shall have delivered to the
Trustee and the NIMS Insurer an Opinion of Counsel, addressed to the Trustee,
the NIMS Insurer and the Depositor, to the effect that the holding by the REMIC
of such REO Property subsequent to three years after its acquisition will not
result in the imposition on the REMIC of taxes on "prohibited transactions"
thereof, as defined in Section 860F of the Code, or cause any of the REMICs
created hereunder to fail to qualify as a REMIC under Federal law at any time
that any Certificates are outstanding. The Master Servicer shall manage,
conserve, protect and operate each REO Property for the Certificateholders
solely for the purpose of its prompt disposition and sale in a manner which does
not cause such REO Property to fail to qualify as "foreclosure property" within
the meaning of Section 860G(a)(8) of the Code or result in the receipt by any of
the REMICs created hereunder of any "income from non-permitted assets" within
the meaning of Section 860F(a)(2)(B) of the Code, or any "net income from
foreclosure property" which is subject to taxation under the REMIC Provisions.

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

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

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

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

                                       85

<PAGE>

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

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

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

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

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

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

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

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

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

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

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

                                       86

<PAGE>

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

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

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

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

          (e) Subject to the time constraints set forth in Section 3.23(a), each
REO Disposition shall be carried out by the Master Servicer in a manner, at such
price and upon such terms and conditions as shall be in conformity with the
requirements of the Loss Mitigation Procedures and as shall be normal and usual
in its Servicing Standard.

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

          (g) The Master Servicer shall file information returns with respect to
the receipt of mortgage interest received in a trade or business, reports of
foreclosures and abandonments of any

                                       87

<PAGE>

Mortgaged Property and cancellation of indebtedness income with respect to any
Mortgaged Property as required by Sections 6050H, 6050J and 6050P of the Code,
respectively. Such reports shall be in form and substance sufficient to meet the
reporting requirements imposed by such Sections 6050H, 6050J and 6050P of the
Code.

          SECTION 3.24. Obligations of the Master Servicer in Respect of
                        Prepayment Interest Shortfalls.

          Not later than 3:00 p.m. New York time on each Master Servicer
Remittance Date, the Master Servicer shall remit to the Distribution Account an
amount ("Compensating Interest") equal to the lesser of (A) the aggregate of the
Prepayment Interest Shortfalls for the related Distribution Date and (B) its
aggregate Servicing Fee received in the related Due Period, any interest or
investment income earned on funds deposited in the Collection Account and any
Prepayment Interest Excess earned during the related Prepayment Period. The
Master Servicer shall not have the right to reimbursement for any amounts
remitted to the Trustee in respect of Compensating Interest. Such amounts so
remitted shall be included in the Available Funds and distributed therewith on
the next Distribution Date. The Master Servicer shall not be obligated to pay
Compensating Interest with respect to Relief Act Interest Shortfalls.

          SECTION 3.25. [Reserved].

          SECTION 3.26. Obligations of the Master Servicer in Respect of
                        Mortgage Rates and Monthly Payments.

          In the event that a shortfall in any collection on or liability with
respect to the Mortgage Loans in the aggregate results from or is attributable
to adjustments to Mortgage Rates, Monthly Payments or Stated Principal Balances
that were made by the Master Servicer in a manner not consistent with the terms
of the related Mortgage Note and this Agreement, the Master Servicer, upon
discovery or receipt of notice thereof, immediately shall deposit in the
Collection Account from its own funds the amount of any such shortfall and shall
indemnify and hold harmless the Trust Fund, the Trustee, the Depositor and any
successor servicer in respect of any such liability. Such indemnities shall
survive the termination or discharge of this Agreement. Notwithstanding the
foregoing, this Section 3.26 shall not limit the ability of the Master Servicer
to seek recovery of any such amounts from the related Mortgagor under the terms
of the related Mortgage Note, as permitted by law.

          SECTION 3.27. Solicitations.

          From and after the Closing Date, the Master Servicer agrees that it
will not take any action or permit or cause any action to be taken by any of its
agents and Affiliates, or by any independent contractors or independent mortgage
brokerage companies on the Master Servicer's behalf, to personally, by
telephone, mail or electronic mail, solicit the Mortgagor under any Mortgage
Loan for the purpose of refinancing such Mortgage Loan; PROVIDED, that the
Master Servicer may solicit any Mortgagor for whom the Master Servicer has
received a request for verification of mortgage, a request for demand for
payoff, a mortgagor initiated written or verbal communication indicating a
desire to prepay the related Mortgage Loan, another mortgage company

                                       88

<PAGE>

has pulled a credit report on the mortgagor or the mortgagor initiates a title
search; provided further, it is understood and agreed that promotions undertaken
by the Master Servicer or any of its Affiliates which (i) concern optional
insurance products or other additional products or (ii) are directed to the
general public at large, including, without limitation, mass mailings based on
commercially acquired mailing lists, newspaper, radio and television
advertisements shall not constitute solicitation under this Section, nor is the
Master Servicer prohibited from responding to unsolicited requests or inquiries
made by a Mortgagor or an agent of a Mortgagor. Furthermore, the Master Servicer
shall be permitted to include in its monthly statements to borrowers or
otherwise, statements regarding the availability of the Master Servicer's
counseling services with respect to refinancing mortgage loans.

          SECTION 3.28. Reserve Fund.

          No later than the Closing Date, the Trustee shall establish and
maintain with itself a separate, segregated trust account titled, "Reserve Fund,
Wells Fargo Bank Minnesota, N.A., as Trustee, in trust for registered Holders of
Option One Mortgage Loan Trust 2001-4, Asset-Backed Certificates, Series
2001-4." On the Closing Date, the Depositor will deposit, or cause to be
deposited, into the Reserve Fund $1,000.

          On each Distribution Date as to which there is a Net WAC Rate
Carryover Amount payable to the Class A Certificates or the Mezzanine
Certificates, the Trustee has been directed by the Class C Certificateholders
to, and therefore will, deposit into the Reserve Fund the amounts described in
Section 4.01(d)(viii), rather than distributing such amounts to the Class C
Certificateholders. On each such Distribution Date, the Trustee shall hold all
such amounts for the benefit of the Holders of the Class A Certificates and the
Mezzanine Certificates, and will distribute such amounts to the Holders of the
Class A Certificates and the Mezzanine Certificates in the amounts and
priorities set forth in Section 4.01(d). If no Net WAC Rate Carryover Amounts
are payable on a Distribution Date, the Trustee shall deposit into the Reserve
Fund on behalf of the Class C Certificateholders, from amounts otherwise
distributable to the Class C Certificateholders, an amount such that when added
to other amounts already on deposit in the Reserve Fund, the aggregate amount on
deposit therein is equal to $1,000.

          For federal and state income tax purposes, the Class C
Certificateholders will be deemed to be the owners of the Reserve Fund and all
amounts deposited into the Reserve Fund (other than the initial deposit therein
of $1,000) shall be treated as amounts distributed by REMIC 3 to the Holders of
the Class C Certificates. Upon the termination of the Trust, or the payment in
full of the Class A Certificates and the Mezzanine Certificates, all amounts
remaining on deposit in the Reserve Fund will be released by the Trust and
distributed to the Class C Certificateholders or their designees. The Reserve
Fund will be part of the Trust but not part of any REMIC and any payments to the
Holders of the Class A Certificates or the Mezzanine Certificates of Net WAC
Rate Carryover Amounts will not be payments with respect to a "regular interest"
in a REMIC within the meaning of Code Section 860(G)(a)(1).

          By accepting a Class C Certificate, each Class C Certificateholder
hereby agrees to direct the Trustee, and the Trustee hereby is directed, to
deposit into the Reserve Fund the amounts described above on each Distribution
Date as to which there is any Net WAC Rate Carryover

                                       89

<PAGE>

Amount rather than distributing such amounts to the Class C Certificateholders.
By accepting a Class C Certificate, each Class C Certificateholder further
agrees that such direction is given for good and valuable consideration, the
receipt and sufficiency of which is acknowledged by such acceptance.

          At the direction of the Holders of a majority in Percentage Interest
in the Class C Certificates, the Trustee shall direct any depository institution
maintaining the Reserve Fund to invest the funds in such account in one or more
Permitted Investments bearing interest or sold at a discount, and maturing,
unless payable on demand, (i) no later than the Business Day immediately
preceding the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if a Person other than the Trustee or an
Affiliate manages or advises such investment, and (ii) no later than the date on
which such funds are required to be withdrawn from such account pursuant to this
Agreement, if the Trustee or an Affiliate manages or advises such investment. If
no investment direction of the Holders of a majority in Percentage Interest in
the Class C Certificates with respect to the Reserve Fund is received by the
Trustee, the Trustee shall invest the funds in such account in Permitted
Investments managed by the Trustee or an Affiliate of the kind described in
clause (vi) of the definition of Permitted Investments.

          For federal tax return and information reporting, the right of the
Class A Certificateholders and the Mezzanine Certificateholders to receive
payments from the Reserve Fund in respect of any Net Wac Rate Carryover Amount
shall be assigned a value of zero.

          SECTION 3.29. Advance Facility.

          (a) The Trustee on behalf of the Trust Fund, with the consent of the
Master Servicer and the NIMS Insurer, is hereby authorized to enter into a
facility with any Person which provides that such Person (an "Advancing Person")
may make all or a portion of the Advances and/or Servicing Advances to the Trust
Fund under this Agreement, although no such facility shall reduce or otherwise
affect the Master Servicer's obligation to fund such Advances and/or Servicing
Advances. To the extent that an Advancing Person makes all or a portion of any
Advance or any Servicing Advance and provides the Trustee with notice
acknowledged by the Servicer that such Advancing Person is entitled to
reimbursement, such Advancing Person shall be entitled to receive reimbursement
pursuant to this Agreement for such amount to the extent provided in Section
3.29(b). Such notice from the Advancing Person must specify the amount of the
reimbursement and must specify which Section of this Agreement permits the
applicable Advance or Servicing Advance to be reimbursed. The Trustee shall be
entitled to rely without independent investigation on the Advancing Person's
statement with respect to the amount of any reimbursement pursuant to this
Section 3.29 and with respect to the Advancing Person's statement with respect
to the Section of this Agreement that permits the applicable Advance or
Servicing Advance to be reimbursed. An Advancing Person whose obligations are
limited to the making of Advances and/or Servicing Advances shall not be
required to meet the qualifications of a Master Servicer or a Sub-Servicer
pursuant to Section 6.06 hereof and will not be deemed to be a Sub-Servicer
under this Agreement. If the terms of a facility proposed to be entered into
with an Advancing Person by the Trust Fund would not materially and adversely
affect the interests of any Certificateholder, then the NIMS Insurer shall not
withhold its consent to the Trust Fund's entering such facility.

                                       90

<PAGE>

          (b) If an advancing facility is entered into, then the Master Servicer
shall not be permitted to reimburse itself therefor under Section 3.11(ii),
Section 3.11(iii), Section 3.11(v), Section 3.11(vi) Section 3.11(vii) and
Section 4.04(b) prior to the remittance to the Trust Fund, but instead the
Master Servicer shall include such amounts in the applicable remittance to the
Trustee made pursuant to Section 3.10(a). The Trustee is hereby authorized to
pay to the Advancing Person, reimbursements for Advances and Servicing Advances
from the Distribution Account to the same extent the Master Servicer would have
been permitted to reimburse itself for such Advances and/or Servicing Advances
in accordance with Section 3.11(ii), Section 3.11(iii), Section 3.11(v), Section
3.11(vi), Section 3.11(vii) or Section 4.04(b), as the case may be, had the
Master Servicer itself funded such Advance or Servicing Advance. The Trustee is
hereby authorized to pay directly to the Advancing Person such portion of the
Servicing Fee as the parties to any advancing facility agree.

          (c) All Advances and Servicing Advances made pursuant to the terms of
this Agreement shall be deemed made and shall be reimbursed on a "first in-first
out" (FIFO) basis.

          SECTION 3.30. PMI Policy; Claims Under the PMI Policy.

          Notwithstanding anything to the contrary elsewhere in this Article
III, the Master Servicer shall not agree to any modification or assumption of a
PMI Mortgage Loan or take any other action with respect to a PMI Mortgage Loan
that could result in denial of coverage under the PMI Policy. The Master
Servicer shall notify the PMI Insurer that the Trustee, on behalf of the
Certificateholders, is the Insured, as that term is defined in the PMI Policy,
of each PMI Mortgage Loan. The Master Servicer shall, on behalf of the Trustee,
prepare and file on a timely basis with the PMI Insurer, with a copy to the
Trustee, all claims which may be made under the PMI Policy with respect to the
PMI Mortgage Loans. Consistent with all rights and obligations hereunder, the
Master Servicer shall take all actions required under the PMI Policy as a
condition to the payment of any such claim. Any amount received from the PMI
Insurer with respect to any such PMI Mortgage Loan shall be deposited by the
Master Servicer, no later than two Business Days following receipt thereof, into
the Collection Account.

                                  FLOW OF FUNDS

          SECTION 4.01. Distributions.

          (a) On the first Distribution Date, the Initial Deposit will be
transferred from the Initial Deposit Account to the Distribution Account for
inclusion in the Available Funds for such Distribution Date. On each
Distribution Date, the Trustee shall withdraw from the Distribution Account that
portion of Available Funds for such Distribution Date consisting of the Interest
Remittance Amount for such Distribution Date, and make the following
disbursements and transfers in the order of priority described below, in each
case to the extent of the Interest Remittance Amount remaining for such
Distribution Date:

          (i) concurrently, to the Holders of the Class A Certificates and the
     Class S Certificates, the related Monthly Interest Distributable Amount and
     the Unpaid Interest Shortfall Amount, if any, for each such class for such
     Distribution Date, on a PRO RATA basis based on the entitlement of each
     such class pursuant to this clause (i);

          (ii) to the Holders of the Class M-1 Certificates, the Monthly
     Interest Distributable Amount allocable to such Certificates;

          (iii) to the Holders of the Class M-2 Certificates, the Monthly
     Interest Distributable Amount allocable to such Certificates; and

          (iv) to the Holders of the Class M-3 Certificates, the Monthly
     Interest Distributable Amount allocable to such Certificates.

          (b) On each Distribution Date (a) prior to the Stepdown Date or (b) on
which a Trigger Event is in effect, the Trustee shall withdraw from the
Distribution Account an amount equal to the Principal Distribution Amount and
distribute to the Holders of the Class A Certificates and the Mezzanine
Certificates the following amounts, in the following order of priority, in each
case to the extent of the Principal Distribution Amount remaining for such
Distribution Date:

          (i) to the Holders of the Class A Certificates, until the Certificate
     Principal Balance thereof has been reduced to zero;

          (ii) to the Holders of the Class M-1 Certificates, until the
     Certificate Principal Balance thereof has been reduced to zero;

          (iii) to the Holders of the Class M-2 Certificates, until the
     Certificate Principal Balance thereof has been reduced to zero; and

          (iv) to the Holders of the Class M-3 Certificates, until the
     Certificate Principal Balance thereof has been reduced to zero.

     Amount and any other amounts required by Section 3.28;

All such credits and disbursements with respect to a Book-Entry Certificate are

<PAGE>

          In the case of information furnished pursuant to subclauses (i)

as is reasonably necessary to provide to such Person a statement containing the
information set forth in subclauses (i) through (iii) above, aggregated for such
calendar year or applicable portion thereof during which such Person was a

satisfied to the extent that substantially comparable information shall be

requirements of the Code as are in force from time to time.

          (c) On each Distribution Date, the Trustee shall forward to the NIMS

time during the calendar year was a Class R Certificateholder, if requested in
writing by such Person, such information as is reasonably necessary to provide
to such Person a statement containing the information provided pursuant to the

          SECTION 4.04. Remittance Reports; Advances.

          (a) On the second Business Day following each Determination Date but
in no event later than the earlier of (i) such date which would allow the
indenture trustee to submit a claim to the NIMS Insurer under the Indenture so
as to allow a timely payment by the NIMS Insurer under the insurance policy
related to the notes insured by the NIMS Insurer and (ii) the 20th day of each
month (or if such 20th day is not a Business Day, the preceding Business Day),
the Master Servicer shall deliver to the Trustee and the NIMS Insurer by
telecopy or electronic mail (or by such other means as the Master Servicer and
the Trustee may agree from time to time) a Remittance Report with respect to the
related Distribution Date; provided, however, that the Remittance Report will
not contain information concerning the PMI Mortgage Loans until such time as the
PMI Insurer has provided the Master Servicer with complete information
concerning the PMI Mortgage Loans as set forth in the side letter between the
Master Servicer and the PMI Insurer. Not later than the 20th day of each month
(or if such 20th day is not a Business Day, the preceding Business Day), the
Master Servicer shall deliver or cause to be delivered to the Trustee in
addition to the information provided on the Remittance Report, such other
information reasonably available to it with respect to the Mortgage Loans as the
Trustee may reasonably require to perform the calculations necessary to make

                                       98

<PAGE>

the distributions contemplated by Section 4.01 and to prepare the statements to
Certificateholders contemplated by Section 4.03. The Trustee shall not be
responsible to recompute, recalculate or verify any information provided to it
by the Master Servicer.

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

          On or before 3:00 p.m. New York time on the Master Servicer Remittance
Date, the Master Servicer shall remit in immediately available funds to the
Trustee for deposit in the Distribution Account an amount equal to the aggregate
amount of Advances, if any, to be made in respect of the Mortgage Loans and REO
Properties for the related Distribution Date either (i) from its own funds or
(ii) from the Collection Account, to the extent of funds held therein for future
distribution (in which case it will cause to be made an appropriate entry in the
records of Collection Account that amounts held for future distribution have
been, as permitted by this Section 4.04, used by the Master Servicer in
discharge of any such Advance) or (iii) in the form of any combination of (i)
and (ii) aggregating the total amount of Advances to be made by the Master
Servicer with respect to the Mortgage Loans and REO Properties. Any amounts held
for future distribution used by the Master Servicer to make an Advance as
permitted in the preceding sentence or withdrawn by the Master Servicer as
permitted in Section 3.11(a)(ii) in reimbursement of Advances previously made
shall be appropriately reflected in the Master Servicer's records and replaced
by the Master Servicer by deposit in the Collection Account on or before any
future Master Servicer Remittance Date to the extent that the Available Funds
for the related Distribution Date (determined without regard to Advances to be
made on the Master Servicer Remittance Date) shall be less than the total amount
that would be distributed to the Classes of Certificateholders pursuant to
Section 4.01 on such Distribution Date if such amounts held for future
distributions had not been so used to make Advances or reimburse for previously
made Advances. The Trustee will provide notice to the NIMS Insurer and the
Master Servicer by telecopy by the Close of Business on any Master Servicer
Remittance Date in the event that the amount remitted by the Master Servicer to
the Trustee on such date is less than the Advances required to be made by the
Master Servicer for the related Distribution Date, as set forth in the related
Remittance Report.

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

                                       99

<PAGE>

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

          SECTION 4.05. Pre-Funding Account.

          (a) No later than the Closing Date, the Trustee shall establish and
maintain a segregated trust account that is an Eligible Account, which shall be
titled "Pre-Funding Account, Wells Fargo Bank Minnesota, N.A., as trustee for
the registered holders of Option One Mortgage Loan Trust 2001-4, Asset-Backed
Certificates, Series 2001-4" (the "Pre-Funding Account"). The Trustee shall,
promptly upon receipt, deposit in the Pre-Funding Account and retain therein the
Original Pre-Funded Amount remitted on the Closing Date to the Trustee by the
Depositor. Funds deposited in the Pre-Funding Account shall be held in trust by
the Trustee for the Certificateholders for the uses and purposes set forth
herein.

          (b) The Trustee will invest funds deposited in the Pre-Funding Account
as directed by the Master Servicer in Permitted Investments with a maturity date
(i) no later than the Business Day immediately preceding the date on which such
funds are required to be withdrawn from such account pursuant to this Agreement,
if a Person other than the Trustee or an Affiliate manages or advises such
investment, (ii) no later than the date on which such funds are required to be
withdrawn from such account pursuant to this Agreement, if the Trustee or an
Affiliate manages or advises such investment or (iii) within one Business Day of
the Trustee's receipt thereof. For federal income tax purposes, the Master
Servicer shall be the owner of the Pre-Funding Account and shall report all
items of income, deduction, gain or loss arising therefrom. All income and gain
realized from investment of funds deposited in the Pre-Funding Account shall be
transferred to the Interest Coverage Account at the following times: (i) on the
Business Day immediately preceding each Distribution Date, if a Person other
than the Trustee or an Affiliate of the Trustee manages or advises such
investment, or on each Distribution Date, if the Trustee or an Affiliate of the
Trustee manages or advises such investment, (ii) on the Business Day immediately
preceding each Subsequent Transfer Date, if a Person other than the Trustee or
an Affiliate of the Trustee manages or advises such investment, or on each
Subsequent Transfer Date, if the Trustee or an Affiliate of the Trustee manages
or advises such investment or (iii) within one Business Day of the Trustee's
receipt thereof. The Master Servicer shall deposit in the Pre-Funding Account
the amount of any net loss incurred in respect of any such Permitted Investment
immediately upon realization of such loss without any right of reimbursement
therefor. At no time will the Pre-Funding Account be an asset of any REMIC
created hereunder.

          (c) Amounts on deposit in the Pre-Funding Account shall be withdrawn
by the Trustee as follows:

          (i) On any Subsequent Transfer Date, the Trustee shall withdraw from
     the Pre- Funding Account an amount equal to 100% of the Stated Principal
     Balances of the Subsequent Mortgage Loans transferred and assigned to the
     Trustee for deposit in the

                                       100

<PAGE>

     Mortgage Pool on such Subsequent Transfer Date and pay such amount to or
     upon the order of the Depositor upon satisfaction of the conditions set
     forth in Section 2.08 with respect to such transfer and assignment;

          (ii) If the amount on deposit in the Pre-Funding Account (exclusive of
     investment income) has not been reduced to zero during the Funding Period,
     on the day immediately following the termination of the Funding Period, the
     Trustee shall deposit into the Distribution Account any amounts remaining
     in the Pre-Funding Account (exclusive of investment income) for
     distribution in accordance with the terms hereof;

          (iii) To withdraw any amount not required to be deposited in the
     Pre-Funding Account or deposited therein in error; and

          (iv) To clear and terminate the Pre-Funding Account upon the earlier
     to occur of (A) the Distribution Date immediately following the end of the
     Funding Period and (B) the termination of this Agreement, with any amounts
     remaining on deposit therein being paid to the Holders of the Certificates
     then entitled to distributions in respect of principal.

          Withdrawals pursuant to clauses (i), (ii) and (iii) shall be treated
as contributions of cash to REMIC 1 on the date of withdrawal.

          SECTION 4.06. Interest Coverage Account.

          (a) No later than the Closing Date, the Trustee shall establish and
maintain a segregated trust account that is an Eligible Account, which shall be
titled "Interest Coverage Account, Wells Fargo Bank Minnesota, N.A., as trustee
for the registered holders of Option One Mortgage Loan Trust 2001-4,
Asset-Backed Certificates, Series 2001-4" (the "Interest Coverage Account"). The
Trustee shall, promptly upon receipt, deposit in the Interest Coverage Account
and retain therein the Interest Coverage Amount remitted on the Closing Date to
the Trustee by the Depositor. Funds deposited in the Interest Coverage Account
shall be held in trust by the Trustee for the Certificateholders for the uses
and purposes set forth herein.

          (b) For federal income tax purposes, the Master Servicer shall be the
owner of the Interest Coverage Account and shall report all items of income,
deduction, gain or loss arising therefrom. At no time will the Interest Coverage
Account be an asset of any REMIC created hereunder. All income and gain realized
from investment of funds deposited in the Interest Coverage Account shall be for
the sole and exclusive benefit of the Master Servicer and shall be remitted by
the Trustee to the Master Servicer no later than the first Business Day
following receipt of such income and gain by the Trustee. The Master Servicer
shall deposit in the Interest Coverage Account the amount of any net loss
incurred in respect of any such Permitted Investment immediately upon
realization of such loss.

          (c) On each Distribution Date during the Funding Period and on the
Distribution Date immediately following the end of the Funding Period, the
Trustee shall withdraw from the Interest Coverage Account and deposit in the
Distribution Account an amount equal to 30 days' interest on the excess, if any,
of the Original Pre-Funded Amount over the aggregate Principal

                                       101

<PAGE>

Balance of Subsequent Mortgage Loans that both (i) had a Due Date during the Due
Period relating to such Distribution Date and (ii) had a Subsequent Cut-off Date
prior to the first day of the month in which such Distribution Date occurs, at a
per annum rate equal to the Pass-Through Rate of the Offered Certificates for
such Distribution Date, with the Pass-Through Rate on the Class A Certificates
and the Mezzanine Certificates, solely for the purposes of the foregoing
calculation, each being multiplied by a fraction, the numerator of which is the
actual number of days in the Accrual Period for such Class for such Distribution
Date, and the denominator of which is 30. Such withdrawal and deposit shall be
treated as a contribution of cash by the Master Servicer to REMIC 1, REMIC 2 and
REMIC 3 on the date thereof with REMIC 3 receiving that portion of the
contribution, if any, to the extent that the rate of LIBOR used to calculate the
Pass-Through Rate on the Class A Certificates and the Mezzanine Certificates for
such Distribution Date exceeds 2.37625% per annum. Immediately following any
such withdrawal and deposit, and immediately following the conveyance of any
Subsequent Mortgage Loans to the Trust on any Subsequent Transfer Date, the
Trustee shall withdraw from the Interest Coverage Account and remit to the
Master Servicer or its designee an amount equal to the excess, if any, of the
amount remaining in such Interest Coverage Account over the amount that would be
required to be withdrawn therefrom (assuming sufficient funds therein) pursuant
to the preceding sentence on each subsequent Distribution Date, if any, that
will occur during the Funding Period or that will be the Distribution Date
immediately following the end of the Funding Period, if no Subsequent Mortgage
Loans were acquired by the Trust Fund after the end of the Prepayment Period
relating to the current Distribution Date (assuming that LIBOR remains constant
at the level of LIBOR applicable to the calculation of the Pass-Through Rate for
the Class A Certificates and the Mezzanine Certificates for the current
Distribution Date).

          (d) Upon the earliest of (i) the Distribution Date immediately
following the end of the Funding Period, (ii) the reduction of the Certificate
Principal Balances of the Certificates to zero or (iii) the termination of this
Agreement in accordance with Section 10.01, any amount remaining on deposit in
the Interest Coverage Account after distributions pursuant to paragraph (c)
above shall be withdrawn by the Trustee and paid to the Master Servicer or its
designee.

          SECTION 4.07. Distributions on the REMIC Regular Interests.

          (a) On each Distribution Date, the Trustee shall cause the Available
Funds from the Distribution Account to make the following disbursements and
transfers, in the following order of priority, to be distributed by REMIC 1 to
REMIC 2 on account of the REMIC 1 Regular Interests or withdrawn from the

     amount equal to (A) the Uncertificated Accrued Interest for such
     Distribution Date, plus (B) any amounts in respect thereof remaining unpaid

     Interest LT1A and REMIC 1 Regular Interest LT1P in an amount equal to (A)
     the Uncertificated Accrued Interest for such Distribution Date, plus (B)
     any amounts in respect thereof remaining unpaid from previous Distribution
     Dates; and

                                       102

<PAGE>

          (ii) on each of the first two Distribution Dates, to the Holders of
     the Class R Certificates (in respect of the Class R-1 Interest), in an
     amount equal to the excess, if any, of (A) the aggregate amount received or
     advanced in respect of interest on the Mortgage Loans for such Distribution
     Dates over (B) the aggregate amount of Uncertificated Accrued Interest
     payable to the Holders of REMIC I Regular Interests on such Distribution
     Dates;

          (2) second, to the Holders of REMIC 1 Regular Interests, in an amount
     equal to the remainder of the Available Funds for such Distribution Date
     after the distributions made pursuant to clause (1) above, allocated as
     follows:

               (a) to the Holders of REMIC 1 Regular Interest LT1P, on the
          Distribution Date immediately following the expiration of the latest
          Prepayment Charge as identified on the Prepayment Charge Schedule or
          any Distribution Date thereafter until $100 has been distributed
          pursuant to this clause;

               (b) to the Holders of REMIC 1 Regular Interest LT1A, until the
          Uncertificated Principal Balance of REMIC 1 Regular Interest LT1A is
          reduced to zero;

               (c) to the Holders of REMIC 1 Regular Interest LT1B, until the
          Uncertificated Principal Balance of REMIC 1 Regular Interest LT1B is
          reduced to zero; then

               (d) any remaining amount to the Holders of the Class R
          Certificates (in respect of the Class R-1 Interest).

     On each Distribution Date, all amounts representing Prepayment Charges in
respect of the Mortgage Loans received during the related Prepayment Period will
be distributed by REMIC 1 to the Holders of REMIC 1 Regular Interest LT1P. The
payment of the foregoing amounts to the Holders of REMIC 1 Regular Interest LT1P
shall not reduce the Uncertificated Principal Balance thereof.

          (b) On each Distribution Date, the Trustee shall cause in the
following order of priority, the following amounts to be distributed by REMIC 2
to REMIC 3 on account of the REMIC 2 Regular Interests or withdrawn from the
Distribution Account and distributed to the Holders of the Class R Certificates
(in respect of the Class R-2 Interest), as the case may be:

          (i) first, to the extent of Available Funds, to Holders of REMIC 2
     Regular Interest LT2A, REMIC 2 Regular Interest LT2B, REMIC 2 Regular
     Interest LT2C, REMIC 2 Regular Interest LT2D, REMIC 2 Regular Interest
     LT2E, REMIC 2 Regular Interest LT2F and REMIC 2 Regular Interest LT2P, PRO
     RATA, in an amount equal to (A) the Uncertificated Accrued Interest for
     such Distribution Date, plus (B) any amounts in respect thereof remaining
     unpaid from previous Distribution Dates. Amounts payable as Uncertificated
     Accrued Interest in respect of REMIC 2 Regular Interest LT2F shall be
     reduced when the REMIC 2 Overcollateralized Amount is less than the REMIC 2
     Overcollateralization Target

                                       103

<PAGE>

     Amount, by the lesser of (x) the amount of such difference and (y) the
     Maximum LT2F Uncertificated Accrued Interest Deferral Amount; and

          (ii) second, to the Holders of REMIC 2 Regular Interests, in an amount
     equal to the remainder of the Available Funds for such Distribution Date
     after the distributions made pursuant to clause (i) above, allocated as
     follows:

               (a) to the Holders of REMIC 2 Regular Interest LT2A, 98.00% of
          such remainder, until the Uncertificated Principal Balance of such
          Uncertificated REMIC 2 Regular Interest is reduced to zero;

               (b) to the Holders of REMIC 2 Regular Interest LT2B, REMIC 2
          Regular Interest LT2C, REMIC 2 Regular Interest LT2D and REMIC 2
          Regular Interest LT2E, 1.00% of such remainder, in the same proportion
          as principal payments are allocated to the Corresponding Certificates,
          until the Uncertificated Principal Balances of such REMIC 2 Regular
          Interests are reduced to zero;

               (c) to the Holders of REMIC 2 Regular Interest LT2F, 1.00% of
          such remainder, until the Uncertificated Principal Balance of such
          REMIC 2 Regular Interest is reduced to zero;

               (d) to the Holders of REMIC 2 Regular Interest LT2P, on the
          Distribution Date immediately following the expiration of the latest
          Prepayment Charge as identified on the Prepayment Charge Schedule or
          any Distribution Date thereafter until $100 has been distributed
          pursuant to this clause; then

               (e) any remaining amount to the Holders of the Class R
          Certificates (in respect of the Class R-2 Interest);

provided, however, that 98.00% and 2.00% of any principal payments that are
attributable to an Overcollateralization Release Amount shall be allocated to
Holders of REMIC 2 Regular Interest LT2A and REMIC 2 Regular Interest LT2F,
respectively.

          On each Distribution Date, all amounts representing Prepayment Charges
in respect of the Mortgage Loans received during the related Prepayment Period
will be distributed by REMIC 2 to the Holders of REMIC 2 Regular Interest LT2P.
The payment of the foregoing amounts to the Holders of REMIC 2 Regular Interest
LT2P shall not reduce the Uncertificated Principal Balance thereof.

          SECTION 4.08. Allocation of Realized Losses.

          (a) All Realized Losses on the Mortgage Loans allocated to any Regular
Certificate shall be allocated by the Trustee on each Distribution Date as
follows: first, to Net Monthly Excess Cashflow; second, to the Class C
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; third, to the Class M-3 Certificates, until the Certificate Principal
Balance thereof has been reduced to zero; fourth, to the Class M-2 Certificates,
until the Certificate

                                       104

<PAGE>

Principal Balance thereof has been reduced to zero; and fifth, to the Class M-1
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero. All Realized Losses to be allocated to the Certificate Principal
Balances of all Classes on any Distribution Date shall be so allocated after the
actual distributions to be made on such date as provided above. All references
above to the Certificate Principal Balance of any Class of Certificates shall be
to the Certificate Principal Balance of such Class immediately prior to the
relevant Distribution Date, before reduction thereof by any Realized Losses, in
each case to be allocated to such Class of Certificates, on such Distribution
Date.

          Any allocation of Realized Losses to a Mezzanine Certificate on any
Distribution Date shall be made by reducing the Certificate Principal Balance
thereof by the amount so allocated; any allocation of Realized Losses to a Class
C Certificate shall be made by reducing the amount otherwise payable in respect
thereof pursuant to Section 4.01(d)(x). No allocations of any Realized Losses
shall be made to the Certificate Principal Balances of the Class A Certificates
or the Class P Certificates.

          (b) All Realized Losses on the Mortgage Loans shall be deemed to have
been allocated by the Trustee on each Distribution Date to REMIC 1 Regular
Interest LT1A until the Uncertificated Principal Balance has been reduced to
zero and then to REMIC 1 Regular Interest LT1B until the Uncertificated
Principal Balance has been reduced to zero

          (c) All Realized Losses on the Mortgage Loans shall be deemed to have
been allocated in the specified percentages, as follows: first, to
Uncertificated Accrued Interest payable to the REMIC 2 Regular Interest LT2A and
REMIC 2 Regular Interest LT2F up to an aggregate amount equal to the REMIC 2
Interest Loss Allocation Amount, 98% and 2%, respectively; second, to the
Uncertificated Principal Balances of REMIC 2 Regular Interest LT2A and REMIC 2
Regular Interest LT2F up to an aggregate amount equal to the REMIC 2 Principal
Loss Allocation Amount, 98% and 2%, respectively; third, to the Uncertificated
Principal Balances of REMIC 2 Regular Interest LT2A, REMIC 2 Regular Interest
LT2E and REMIC 2 Regular Interest LT2F, 98%, 1% and 1%, respectively, until the
Uncertificated Principal Balance of REMIC 2 Regular Interest LT2E has been
reduced to zero; fourth, to the Uncertificated Principal Balances of REMIC 2
Regular Interest LT2A, REMIC 2 Regular Interest LT2D and REMIC 2 Regular
Interest LT2F, 98%, 1% and 1%, respectively, until the Uncertificated Principal
Balance of REMIC 2 Regular Interest LT2D has been reduced to zero; and fifth, to
the Uncertificated Principal Balances of REMIC 2 Regular Interest LT2A, REMIC 2
Regular Interest LT2C and REMIC 2 Regular Interest LT2F, 98%, 1% and 1%,
respectively, until the Uncertificated Principal Balance of REMIC 2 Regular
Interest LT2C has been reduced to zero.

                                THE CERTIFICATES

          SECTION 5.01. The Certificates.

          Each of the Class A Certificates, the Class S Certificates, the
Mezzanine Certificates, the Class P Certificates, the Class C Certificates and
the Class R Certificates shall be substantially in the forms annexed hereto as
exhibits, and shall, on original issue, be executed, authenticated and delivered
by the Trustee to or upon the order of the Depositor concurrently with the sale
and assignment to the Trustee of the Trust Fund. The Offered Certificates shall
be initially evidenced by one or more Certificates representing a Percentage
Interest with a minimum dollar denomination of $50,000 and integral dollar
multiples of $1.00 in excess thereof, except that one Certificate of each such
Class of Certificates may be in a different denomination so that the sum of the
denominations of all outstanding Certificates of such Class shall equal the
Certificate Principal Balance or Notional Amount of such Class on the Closing
Date. The Class P Certificates, the Class C Certificates and the Class R
Certificates are issuable in any Percentage Interests; PROVIDED, HOWEVER, that
the sum of all such percentages for each such Class totals 100% and no more than
ten Certificates of each Class may be issued and outstanding at any one time.

          The Certificates shall be executed on behalf of the Trust by manual or
facsimile signature on behalf of the Trustee by a Responsible Officer.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Trustee shall bind the Trust, notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificate. No Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose, unless such Certificate shall have been
manually authenticated by the Trustee substantially in the form provided for
herein, and such authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. Subject to Section 5.02(c), the Offered Certificates
shall be Book-Entry Certificates. The other Classes of Certificates shall not be
Book-Entry Certificates.

          SECTION 5.02. Registration of Transfer and Exchange of Certificates.

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

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

                                       106

<PAGE>

          At the option of the Certificateholders, Certificates may be exchanged
for other Certificates in authorized denominations and the same aggregate
Percentage Interests, upon surrender of the Certificates to be exchanged at any
such office or agency. Whenever any Certificates are so surrendered for
exchange, the Trustee shall execute on behalf of the Trust and authenticate and
deliver the Certificates which the Certificateholder making the exchange is
entitled to receive. Every Certificate presented or surrendered for registration
of transfer or exchange shall (if so required by the Trustee or the Certificate
Registrar) be duly endorsed by, or be accompanied by a written instrument of
transfer satisfactory to the Trustee and the Certificate Registrar duly executed
by, the Holder thereof or his attorney duly authorized in writing. In addition,
with respect to each Class R Certificate, the holder thereof may exchange, in
the manner described above, such Class R Certificate for three separate
certificates, each representing such holder's respective Percentage Interest in
the Class R-1 Interest, the Class R-2 Interest and the Class R-3 Interest,
respectively, in each case that was evidenced by the Class R Certificate being
exchanged.

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

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

          (c) If (i)(x) the Depository or the Depositor advises the Trustee in
writing that the Depository is no longer willing or able to discharge properly
its responsibilities as Depository and

                                       107

<PAGE>

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

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

          Each Transferee of a Mezzanine Certificate will be deemed to have
represented by virtue of its purchase or holding of such Certificate (or
interest therein) that either (a) such Transferee is not a Plan or purchasing
such Certificate with Plan Assets, (b) it has acquired and is holding such
Certificate in reliance on Prohibited Transaction Exemption ("PTE") 96-59, 55
Fed. Reg. 36724 (September 6, 1990), as amended by PTE 2000-58, 65 Fed. Reg.
67765 (November 13, 2000) (the "Exemption"), and that it understands that there
are certain conditions to the availability of the Exemption including that such
Certificate must be rated, at the time of purchase, not lower

                                       108

<PAGE>

than "BBB-" (or its equivalent) by a Rating Agency or (c) the following
conditions are satisfied: (i) such Transferee is an insurance company, (ii) the
source of funds used to purchase or hold such Certificate (or interest therein)
is an "insurance company general account" (as defined in U.S. Department of
Labor Prohibited Transaction Class Exemption ("PTCE") 95-60, and (iii) the
conditions set forth in Sections I and III of PTCE 95-60 have been satisfied.

          No transfer of a Class C Certificate, Class P Certificate or Class R
Certificate or any interest therein shall be made to any Plan subject to ERISA
or Section 4975 of the Code, any Person acting, directly or indirectly, on
behalf of any such Plan or any Person acquiring such Certificates with "Plan
Assets" of a Plan within the meaning of the Department of Labor regulation
promulgated at 29 C.F.R. ss. 2510.3-101 ("Plan Assets") unless the Depositor,
the Trustee and the Master Servicer are provided with an Opinion of Counsel
which establishes to the satisfaction of the Depositor, the Trustee and the
Master Servicer that the purchase of such Certificates is permissible under
applicable law, will not constitute or result in any prohibited transaction
under ERISA or Section 4975 of the Code and will not subject the Depositor, the
Master Servicer, the Trustee or the Trust Fund to any obligation or liability
(including obligations or liabilities under ERISA or Section 4975 of the Code)
in addition to those undertaken in this Agreement, which Opinion of Counsel
shall not be an expense of the Depositor, the Master Servicer, the Trustee or
the Trust Fund. An Opinion of Counsel will not be required in connection with
the initial transfer of any such Certificate by the Depositor to an affiliate of
the Depositor (in which case, the Depositor or any affiliate thereof shall have
deemed to have represented that such affiliate is not a Plan or a Person
investing Plan Assets) and the Trustee shall be entitled to conclusively rely
upon a representation (which, upon the request of the Trustee, shall be a
written representation) from the Depositor of the status of such transferee as
an affiliate of the Depositor.

          If any Class C Certificate, Class P Certificate or Class R Certificate
or any interest therein is acquired or held in violation of the provisions of
the second preceding paragraph, the next preceding permitted beneficial owner
will be treated as the beneficial owner of that Certificate retroactive to the
date of transfer to the purported beneficial owner. Any purported beneficial
owner whose acquisition or holding of any such Certificate or interest therein
was effected in violation of the provisions of the preceding paragraph shall
indemnify and hold harmless the Depositor, the Master Servicer, the NIMS
Insurer, the Trustee and the Trust from and against any and all liabilities,
claims, costs or expenses incurred by those parties as a result of that
acquisition or holding.

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

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

                                       109

<PAGE>

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

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

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

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

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

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

                                       110

<PAGE>

     claim. The terms and conditions of any sale under this clause (v) shall be
     determined in the sole discretion of the Trustee and it shall not be liable
     to any Person having an Ownership Interest in a Class R Certificate as a
     result of its exercise of such discretion.

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

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

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

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

          SECTION 5.03. Mutilated, Destroyed, Lost or Stolen Certificates.

          If (i) any mutilated Certificate is surrendered to the Certificate
Registrar or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate and (ii) there is delivered to
the Trustee, the Depositor, the NIMS Insurer and the Certificate Registrar such
security or indemnity as may be required by them to save each of them harmless,
then, in the absence of notice to the Trustee or the Certificate Registrar that
such Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute on behalf of the Trust, authenticate and deliver, in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like tenor and Percentage Interest. Upon the issuance of any new
Certificate under this Section, the Trustee or the Certificate Registrar may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee and the Certificate Registrar) in
connection therewith. Any duplicate Certificate issued pursuant to this Section,
shall constitute complete and indefeasible evidence of ownership in the Trust,
as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time.

          SECTION 5.04. Persons Deemed Owners.

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

          SECTION 5.05. Appointment of Paying Agent.

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

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

                      THE MASTER SERVICER AND THE DEPOSITOR

          SECTION 6.01. Liability of the Master Servicer and the Depositor.

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

          SECTION 6.02. Merger or Consolidation of, or Assumption of the
                        Obligations of, the Master Servicer or the Depositor.

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

          SECTION 6.03. Limitation on Liability of the Master Servicer and
                        Others.

          Neither the Master Servicer nor any of the directors or officers or
employees or agents of the Master Servicer shall be under any liability to the
Trust or the Certificateholders for any action taken or for refraining from the
taking of any action by the Master Servicer in good faith pursuant to this
Agreement, or for errors in judgment; PROVIDED, HOWEVER, that this provision
shall not protect the Master Servicer or any such Person against any liability
which would otherwise be imposed by reason of its willful misfeasance, bad faith
or negligence in the performance of duties of the Master Servicer or by reason
of its reckless disregard of its obligations and duties of the Master Servicer
hereunder; PROVIDED, FURTHER, that this provision shall not be construed to
entitle the Master Servicer to indemnity in the event that amounts advanced by
the Master Servicer to retire any senior lien exceed Liquidation Proceeds (in
excess of related liquidation expenses) realized with respect to the related
Mortgage Loan. The preceding sentence shall not limit the obligations of the
Master Servicer pursuant to Section 8.05. The Master Servicer and any director
or officer or employee or agent of the Master Servicer may rely in good faith on
any document of any kind PRIMA FACIE properly executed and submitted by any
Person respecting any matters arising hereunder. The Master Servicer and any
director or officer or employee or agent of the Master Servicer shall be
indemnified by the Trust and held harmless against any loss, liability or
expense incurred in connection with any legal action relating to this Agreement
or the Certificates, other than any loss, liability or expense related to any
specific Mortgage Loan or Mortgage Loans (except as any such loss, liability or
expense shall be otherwise reimbursable pursuant to this Agreement) and any
loss, liability or expense incurred by reason of its willful misfeasance, bad
faith or negligence in the performance of duties hereunder or by reason of its
reckless disregard of obligations and duties hereunder. The

                                       113

<PAGE>

Master Servicer may undertake any such action which it may deem necessary or
desirable in respect of this Agreement, and the rights and duties of the parties
hereto and the interests of the Certificateholders hereunder. In such event,
unless the Depositor or the Master Servicer acts without the consent of Holders
of Certificates entitled to at least 51% of the Voting Rights, the reasonable
legal expenses and costs of such action and any liability resulting therefrom
shall be expenses, costs and liabilities of the Trust and the Master Servicer
shall be entitled to be reimbursed therefor from the Collection Account as and
to the extent provided in Section 3.11, any such right of reimbursement being
prior to the rights of the Certificateholders to receive any amount in the
Collection Account. The Master Servicer's right to indemnity or reimbursement
pursuant to this Section shall survive any resignation or termination of the
Master Servicer pursuant to Section 6.04 or 7.01 with respect to any losses,
expenses, costs or liabilities arising prior to such resignation or termination
(or arising from events that occurred prior to such resignation or termination).
This paragraph shall apply to the Master Servicer solely in its capacity as
Master Servicer hereunder and in no other capacities.

          The Master Servicer (except the Trustee if it is required to succeed
the Master Servicer hereunder) indemnifies and holds the Trustee, the Depositor,
the NIMS Insurer and each Certificateholder harmless against any and all claims,
losses, penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments, and any other costs, fees and expenses that the Trustee, the
Depositor, the NIMS Insurer and any Certificateholder may sustain in any way
related to the failure of the Master Servicer to perform its duties and service
the Mortgage Loans in compliance with the terms of this Agreement. The Master
Servicer shall immediately notify the Trustee, the Depositor, the NIMS Insurer
and each Certificateholder if a claim is made that may result in such claims,
losses, penalties, fines, forfeitures, legal fees or related costs, judgments,
or any other costs, fees and expenses, and the Master Servicer shall assume
(with the consent of the Trustee) the defense of any such claim and pay all
expenses in connection therewith, including reasonable counsel fees, and
promptly pay, discharge and satisfy any judgment or decree which may be entered
against the Master Servicer, the Trustee, the Depositor, the NIMS Insurer and/or
Certificateholder in respect of such claim. The provisions of this paragraph
shall survive the termination of this Agreement and the payment of the
outstanding Certificates.

          SECTION 6.04. Master Servicer Not to Resign.

          Subject to the provisions of Section 7.01 and Section 6.02, the Master
Servicer shall not resign from the obligations and duties hereby imposed on it
except (i) upon determination that the performance of its obligations or duties
hereunder are no longer permissible under applicable law or are in material
conflict by reason of applicable law with any other activities carried on by it
or its subsidiaries or Affiliates, the other activities of the Master Servicer
so causing such a conflict being of a type and nature carried on by the Master
Servicer or its subsidiaries or Affiliates at the date of this Agreement or (ii)
upon satisfaction of the following conditions: (a) the Master Servicer has
proposed a successor servicer to the Trustee and the NIMS Insurer in writing and
such proposed successor servicer is reasonably acceptable to the Trustee and the
NIMS Insurer and (b) each Rating Agency shall have delivered a letter to the
Trustee and the NIMS Insurer prior to the appointment of the successor servicer
stating that the proposed appointment of such successor servicer as Master
Servicer hereunder will not result in the reduction or withdrawal of the then
current rating of the Certificates; PROVIDED, HOWEVER, that no such resignation
by the Master Servicer shall become

                                       114

<PAGE>

effective until such successor servicer or, in the case of (i) above, the
Trustee shall have assumed the Master Servicer's responsibilities and
obligations hereunder or the Trustee shall have designated, with the consent of
the NIMS Insurer, a successor servicer in accordance with Section 7.02. Any such
resignation shall not relieve the Master Servicer of responsibility for any of
the obligations specified in Sections 7.01 and 7.02 as obligations that survive
the resignation or termination of the Master Servicer. Any such determination
permitting the resignation of the Master Servicer pursuant to clause (i) above
shall be evidenced by an Opinion of Counsel to such effect delivered to the
Trustee and the NIMS Insurer. Any such determination permitting the resignation
of the Master Servicer shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee and the NIMS Insurer.

          SECTION 6.05. Delegation of Duties.

          In the ordinary course of business, the Master Servicer at any time
may delegate any of its duties hereunder to any Person, including any of its
Affiliates, who agrees to conduct such duties in accordance with standards
comparable to those set forth in Section 3.01. Such delegation shall not relieve
the Master Servicer of its liabilities and responsibilities with respect to such
duties and shall not constitute a resignation within the meaning of Section
6.04. Except as provided in Section 3.02, no such delegation is permitted that
results in the delegee subservicing any Mortgage Loans. The Master Servicer
shall provide the Trustee and the NIMS Insurer with 60 days prior written notice
prior to the delegation of any of its duties to any Person other than any of the
Master Servicer's Affiliates or their respective successors and assigns.

          SECTION 6.06. [Reserved].

          SECTION 6.07. Inspection.

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

Termination") shall occur and be continuing:

          (i) (A) The failure by the Master Servicer to make any Advance; or (B)
     any other failure by the Master Servicer to deposit in the Collection

     Business Day after the date upon which written notice of such failure shall
     have been given to the Master Servicer by the Trustee or to the Trustee by
     the NIMS Insurer or any Holders of a Regular Certificate evidencing at
     least 25% of the Voting Rights; or

          (ii) The failure by the Master Servicer to make any required Servicing
     Advance which failure continues unremedied for a period of 30 days, or the
     failure by the Master Servicer duly to observe or perform, in any material
     respect, any other covenants, obligations or agreements of the Master
     Servicer as set forth in this Agreement, which failure continues unremedied
     for a period of 30 days, after the date (A) on which written notice of such
     failure, requiring the same to be remedied, shall have been given to the

     Holders of a Regular Certificate evidencing at least 25% of the Voting
     Rights or (B) actual knowledge of such failure by a Servicing Officer of
     the Master Servicer; or

          (iii) The entry against the Master Servicer of a decree or order by a
     court or agency or supervisory authority having jurisdiction in the

and obligations of the Master Servicer under this Agreement and the Trustee, or
a successor servicer appointed in accordance with Section 7.02, shall
immediately make such Advance and assume, pursuant to Section 7.02, the duties
of a successor Master Servicer, (y) in the case of (i)(B), (ii), (iii) and (iv)
above, the Trustee shall, at the written direction of the NIMS Insurer or the
Holders of each Class of Regular Certificates evidencing Percentage Interests
aggregating not less than 51%, by notice then given in writing to the Master
Servicer and to the Trustee and (z) in the case of (v) above, the Trustee shall,
at the direction of the NIMS Insurer, by notice then given in writing to the
Master Servicer and to the Trustee, terminate all of the rights and obligations

if such notice is given by the Holders) of such written notice, all authority
and power of the Master Servicer under this Agreement, whether with respect to
the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested
in the Trustee pursuant to and under this Section; and, without limitation, and
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,

including, without limitation, the delivery to the Trustee of all documents and
records requested by it to enable it to assume the Master Servicer's functions

Account or any Servicing Account or that have been deposited by the Master
Servicer in such accounts or thereafter received by the Master Servicer with
respect to the Mortgage Loans or any REO Property received by the Master
Servicer. All reasonable costs and expenses (including attorneys' fees) incurred
in connection with transferring the Mortgage Files to the successor Master
Servicer and amending this Agreement to reflect such succession as Master
Servicer pursuant to this Section shall be paid by the predecessor Master
Servicer (or if the predecessor Master Servicer is the Trustee, the initial
Master Servicer) upon presentation of reasonable documentation of such costs and
expenses and to the extent not paid by the Master Servicer, by the Trust.

<PAGE>

          SECTION 7.02. Trustee to Act; Appointment of Successor.

          (a) Within 90 days of the time the Master Servicer (and the Trustee,
if notice is sent by the Holders) receives a notice of termination pursuant to
Section 7.01 or 6.04, the Trustee (or such other successor Master Servicer as is
approved in accordance with this Agreement) shall be the successor in all
respects to the Master Servicer in its capacity as servicer under this Agreement
and the transactions set forth or provided for herein and shall be subject to
all the responsibilities, duties and liabilities relating thereto placed on the
Master Servicer by the terms and provisions hereof arising on and after its
succession. Notwithstanding the foregoing, the parties hereto agree that the
Trustee, in its capacity as successor Master Servicer, immediately will assume
all of the obligations of the Master Servicer to make advances. Notwithstanding
the foregoing, the Trustee, in its capacity as successor Master Servicer, shall
not be responsible for the lack of information and/or documents that it cannot
obtain through reasonable efforts. As compensation therefor, the Trustee (or
such other successor Master Servicer) shall be entitled to such compensation as
the Master Servicer would have been entitled to hereunder if no such notice of
termination had been given. Notwithstanding the above, (i) if the Trustee is
unwilling to act as successor Master Servicer or (ii) if the Trustee is legally
unable so to act, the Trustee shall appoint or petition a court of competent
jurisdiction to appoint, any established housing and home finance institution,
bank or other mortgage loan or home equity loan servicer having a net worth of
not less than $50,000,000 as the successor to the Master Servicer hereunder in
the assumption of all or any part of the responsibilities, duties or liabilities
of the Master Servicer hereunder; PROVIDED, that the appointment of any such
successor Master Servicer shall be approved by the NIMS Insurer (such approval
not to be unreasonably withheld), as evidenced by the prior written consent of
the NIMS Insurer, and will not result in the qualification, reduction or
withdrawal of the ratings assigned to the Certificates by the Rating Agencies as
evidenced by a letter to such effect from the Rating Agencies. Pending
appointment of a successor to the Master Servicer hereunder, unless the Trustee
is prohibited by law from so acting, the Trustee shall act in such capacity as
hereinabove provided. In connection with such appointment and assumption, the
successor shall be entitled to receive compensation out of payments on Mortgage
Loans in an amount equal to the compensation which the Master Servicer would
otherwise have received pursuant to Section 3.18 (or such other compensation as
the Trustee and such successor shall agree, not to exceed the Servicing Fee).
The appointment of a successor Master Servicer shall not affect any liability of
the predecessor Master Servicer which may have arisen under this Agreement prior
to its termination as Master Servicer to pay any deductible under an insurance
policy pursuant to Section 3.14 or to indemnify the Trustee or the NIMS Insurer
pursuant to Section 6.03), nor shall any successor Master Servicer be liable for
any acts or omissions of the predecessor Master Servicer or for any breach by
such Master Servicer of any of its representations or warranties contained
herein or in any related document or agreement. The Trustee and such successor
shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. All Servicing Transfer Costs shall be paid by
the predecessor Master Servicer upon presentation of reasonable documentation of
such costs, and if such predecessor Master Servicer defaults in its obligation
to pay such costs, such costs shall be paid by the successor Master Servicer or
the Trustee (in which case the successor Master Servicer or the Trustee, as
applicable, shall be entitled to reimbursement therefor from the assets of the
Trust).

          (b) Any successor to the Master Servicer, including the Trustee, shall
during the term of its service as servicer continue to service and administer
the Mortgage Loans for the benefit

                                       118

<PAGE>

of Certificateholders, and maintain in force a policy or policies of insurance
covering errors and omissions in the performance of its obligations as Master
Servicer hereunder and a Fidelity Bond in respect of its officers, employees and
agents to the same extent as the Master Servicer is so required pursuant to
Section 3.14.

          SECTION 7.03. Waiver of Defaults.

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

          SECTION 7.04. Notification to Certificateholders.

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

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

          SECTION 7.05. Survivability of Master Servicer Liabilities.

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

                                  ARTICLE VIII

                                   THE TRUSTEE

          SECTION 8.01. Duties of Trustee.

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

          The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform to the requirements of this Agreement; provided, however, that the
Trustee will not be responsible for the accuracy or content of any such
resolutions, certificates, statements, opinions, reports, documents or other
instruments. If any such instrument is found not to conform to the requirements
of this Agreement in a material manner the Trustee shall take such action as it
deems appropriate to have the instrument corrected, and if the instrument is not
corrected to the Trustee's satisfaction, the Trustee will provide notice thereof
to the Certificateholders and the NIMS Insurer.

          No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own misconduct; PROVIDED, HOWEVER, that:

          (i) prior to the occurrence of a Master Servicer Event of Termination,
     and after the curing of all such Master Servicer Events of Termination
     which may have occurred, the duties and obligations of the Trustee shall be
     determined solely by the express provisions of this Agreement, the Trustee
     shall not be liable except for the performance of such duties and
     obligations as are specifically set forth in this Agreement, no implied
     covenants or obligations shall be read into this Agreement against the
     Trustee and, in the absence of bad faith on the part of the Trustee, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon any certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Agreement;

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

          (iii) the Trustee shall not be personally liable with respect to any
     action taken, suffered or omitted to be taken by it in good faith in
     accordance with the direction of the NIMS Insurer or the Majority
     Certificateholders relating to the time, method and place of

                                       120

<PAGE>

     conducting any proceeding for any remedy available to the Trustee, or
     exercising or omitting to exercise any trust or power conferred upon the
     Trustee, under this Agreement; and

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

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

          SECTION 8.02. Certain Matters Affecting the Trustee.

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

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

          (iii) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Agreement, or to institute, conduct
     or defend any litigation hereunder or in relation hereto, at the request,
     order or direction of any of the Certificateholders or the NIMS Insurer,
     pursuant to the provisions of this Agreement, unless such
     Certificateholders or the NIMS Insurer, as applicable, shall have offered
     to the Trustee reasonable security or indemnity against the costs, expenses
     and liabilities which may be incurred therein or thereby; the right of the
     Trustee to perform any discretionary act enumerated in this Agreement shall
     not be construed as a duty, and the Trustee shall not be answerable for
     other than its negligence or willful misconduct in the performance of any
     such act;

                                       121

<PAGE>

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

          (v) prior to the occurrence of a Master Servicer Event of Termination
     and after the curing of all Master Servicer Events of Termination which may
     have occurred, the Trustee shall not be bound to make any investigation
     into the facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond or other paper or documents, unless requested in writing to do so by
     the NIMS Insurer or the Majority Certificateholder; PROVIDED, HOWEVER, that
     if the payment within a reasonable time to the Trustee of the costs,
     expenses or liabilities likely to be incurred by it in the making of such
     investigation is, in the opinion of the Trustee, not reasonably assured to
     the Trustee by the security afforded to it by the terms of this Agreement,
     the Trustee may require reasonable indemnity against such cost, expense or
     liability as a condition to such proceeding. The reasonable expense of
     every such examination shall be paid by the Master Servicer or the NIMS
     Insurer (if requested by the NIMS Insurer) or, if paid by the Trustee,
     shall be reimbursed by the Master Servicer or the NIMS Insurer (if
     requested by the NIMS Insurer) upon demand and, if not reimbursed by the
     Master Servicer or the NIMS Insurer (if requested by the NIMS Insurer),
     shall be reimbursed by the Trust. Nothing in this clause (v) shall derogate
     from the obligation of the Master Servicer to observe any applicable law
     prohibiting disclosure of information regarding the Mortgagors;

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

          (vii) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys or a custodian; and

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

          SECTION 8.03. Trustee Not Liable for Certificates or Mortgage Loans.

          The recitals contained herein and in the Certificates (other than the
authentication of the Trustee on the Certificates) shall be taken as the
statements of the Depositor, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the validity
or sufficiency of this Agreement or of the Certificates (other than the
signature and authentication of the Trustee on the Certificates) or of any
Mortgage Loan or related document. The Trustee shall not be accountable for the
use or application by the Master Servicer, or for the use or application of any
funds paid to the Master Servicer in respect of the Mortgage Loans or deposited
in or withdrawn from the Collection Account by the Master Servicer. The Trustee
shall at no time have any responsibility or liability for or with respect to the
legality, validity and enforceability of

                                       122

<PAGE>

any Mortgage or any Mortgage Loan, or the perfection and priority of any
Mortgage or the maintenance of any such perfection and priority, or for or with
respect to the sufficiency of the Trust or its ability to generate the payments
to be distributed to Certificateholders under this Agreement, including, without
limitation: the existence, condition and ownership of any Mortgaged Property;
the existence and enforceability of any hazard insurance thereon (other than if
the Trustee shall assume the duties of the Master Servicer pursuant to Section
7.02); the validity of the assignment of any Mortgage Loan to the Trustee or of
any intervening assignment; the completeness of any Mortgage Loan; the
performance or enforcement of any Mortgage Loan (other than if the Trustee shall
assume the duties of the Master Servicer pursuant to Section 7.02); the
compliance by the Depositor, the Originator, the Seller or the Master Servicer
with any warranty or representation made under this Agreement or in any related
document or the accuracy of any such warranty or representation prior to the
Trustee's receipt of notice or other discovery of any non-compliance therewith
or any breach thereof; any investment of monies by or at the direction of the
Master Servicer or any loss resulting therefrom, it being understood that the
Trustee shall remain responsible for any Trust property that it may hold in its
individual capacity; the acts or omissions of any of the Master Servicer (other
than if the Trustee shall assume the duties of the Master Servicer pursuant to
Section 7.02), any Sub-Servicer or any Mortgagor; any action of the Master
Servicer (other than if the Trustee shall assume the duties of the Master
Servicer pursuant to Section 7.02), or any Sub- Servicer taken in the name of
the Trustee; the failure of the Master Servicer or any Sub-Servicer to act or
perform any duties required of it as agent of the Trustee hereunder; or any
action by the Trustee taken at the instruction of the Master Servicer (other
than if the Trustee shall assume the duties of the Master Servicer pursuant to
Section 7.02); PROVIDED, HOWEVER, that the foregoing shall not relieve the
Trustee of its obligation to perform its duties under this Agreement, including,
without limitation, the Trustee's duty to review the Mortgage Files pursuant to
Section 2.01. The Trustee shall have no responsibility for filing any financing
or continuation statement in any public office at any time or to otherwise
perfect or maintain the perfection of any security interest or lien granted to
it hereunder (unless the Trustee shall have become the successor 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 Trustee and may transact any banking and trust business with the
Originator, the Master Servicer, the Depositor or their Affiliates.

          SECTION 8.05. Trustee Fee and Expenses.

          The Trustee shall withdraw from the Distribution Account on each
Distribution Date and pay to itself the Trustee Fee and, to the extent that the
funds therein are at anytime insufficient for such purpose, the Master Servicer
shall pay such fees. The Master Servicer (or the Depositor, if the Trustee
becomes the Master Servicer) will pay or reimburse the Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any of the provisions of this Agreement (including
the reasonable compensation and the expenses and disbursements of its counsel
and of all persons not regularly in its employ and any amounts paid by the
Trustee for the recording of Assignments of Mortgage pursuant to Section 2.01)
except any such expense, disbursement or advance as may arise from its
negligence or bad faith or which is the responsibility of Certificateholders or
the Trustee hereunder. In addition, the Master

                                       123

<PAGE>

Servicer (or the Depositor, if the Trustee becomes the Master Servicer)
covenants and agrees to indemnify the Trustee and its officers, directors,
employees and agents from, and hold it harmless against, any and all losses,
liabilities, damages, claims or expenses incurred in connection with any legal
action relating to this Agreement or the Certificates, other than any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
negligence of the Trustee in the performance of its duties hereunder or by
reason of the Trustee's reckless disregard of obligations and duties hereunder.
This section shall survive termination of this Agreement or the resignation or
removal of any Trustee hereunder. If the Master Servicer (or the Depositor, if
the Trustee becomes the Master Servicer) defaults in its obligations to pay or
reimburse the Trustee any amount as required under this Section 8.05, the
Trustee shall be entitled to be paid or reimbursed such amount at any time from
the assets of the Trust Fund consisting of any amounts on deposit at such time
in the Collection Account or the Distribution Account.

          SECTION 8.06. Eligibility Requirements for Trustee.

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

          SECTION 8.07. Resignation or Removal of Trustee.

          The Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the NIMS Insurer, the
Depositor, the Master Servicer and each Rating Agency. Upon receiving such
notice of resignation, the Depositor shall promptly appoint a successor Trustee
acceptable to the NIMS Insurer by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Trustee and one copy to the
successor Trustee. If no successor Trustee shall have been so appointed and
having accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

          If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 and shall fail to resign after written
request therefor by the Depositor or the NIMS Insurer or if at any time the
Trustee shall be legally unable to act, or shall be adjudged a bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed,
or any public officer

                                       124

<PAGE>

shall take charge or control of the Trustee or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation, then the Depositor,
the Master Servicer or the NIMS Insurer may remove the Trustee. If the
Depositor, the Master Servicer or the NIMS Insurer removes the Trustee under the
authority of the immediately preceding sentence, the Depositor, with the consent
of the NIMS Insurer, shall promptly appoint a successor Trustee by written
instrument, in duplicate, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor trustee.

          The Majority Certificateholders (or the NIMS Insurer upon the failure
of the Trustee to perform its obligations hereunder) may at any time remove the
Trustee by written instrument or instruments delivered to the Master Servicer,
the Depositor and the Trustee; the Depositor shall thereupon use its best
efforts to appoint a successor trustee acceptable to the NIMS Insurer in
accordance with this Section.

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

          SECTION 8.08. Successor Trustee.

          Any successor Trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the NIMS Insurer, the Depositor, the Master
Servicer and to its predecessor Trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor Trustee
shall become effective, and such successor Trustee, without any further act,
deed or conveyance, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor hereunder, with like effect as if
originally named as Trustee. The Depositor, the Master Servicer and the
predecessor Trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for fully and certainly vesting and
confirming in the successor Trustee all such rights, powers, duties and
obligations.

          No successor Trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor Trustee shall
be eligible under the provisions of Section 8.06 and the appointment of such
successor Trustee shall not result in a downgrading of the Regular Certificates
by either Rating Agency, as evidenced by a letter from each Rating Agency.

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

          SECTION 8.09. Merger or Consolidation of Trustee.

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

                                       125

<PAGE>

and 8.08, without the execution or filing of any paper or any further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding.

          SECTION 8.10. Appointment of Co-Trustee or Separate Trustee.

          Notwithstanding any other provisions of this Agreement, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Trust or any Mortgaged Property may at the time be located, the
Depositor and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments to appoint one or more Persons approved by the
Trustee and the NIMS Insurer to act as co-trustee or co-trustees, jointly with
the Trustee, or separate trustee or separate trustees, of all or any part of the
Trust, and to vest in such Person or Persons, in such capacity and for the
benefit of the Certificateholders, such title to the Trust, or any part thereof,
and, subject to the other provisions of this Section 8.10, such powers, duties,
obligations, rights and trusts as the Master Servicer and the Trustee may
consider necessary or desirable. Any such co-trustee or separate trustee shall
be subject to the written approval of the Master Servicer and the NIMS Insurer.
If the Master Servicer and the NIMS Insurer shall not have joined in such
appointment within 15 days after the receipt by it of a request so to do, or in
the case a Master Servicer Event of Termination shall have occurred and be
continuing, the Trustee alone shall have the power to make such appointment. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 8.06, and no notice to
Certificateholders of the appointment of any co-trustee or separate trustee
shall be required under Section 8.08. The Master Servicer shall be responsible
for the fees of any co-trustee or separate trustee appointed hereunder.

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

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

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

          (iii) the Master Servicer and the Trustee, acting jointly and with the
     consent of the NIMS Insurer, may at any time accept the resignation of or
     remove any separate trustee or co-trustee except that following the
     occurrence of a Master Servicer Event of Termination, the Trustee acting
     alone may accept the resignation or remove any separate trustee or co-
     trustee.

                                       126

<PAGE>

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

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

          SECTION 8.11. Limitation of Liability.

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

          SECTION 8.12. Trustee May Enforce Claims Without Possession of
                        Certificates.

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

          (b) The Trustee shall afford the Seller, the Originator, the
Depositor, the Master Servicer, the NIMS Insurer and each Certificateholder upon
reasonable notice during normal business hours, access to all records maintained
by the Trustee in respect of its duties hereunder and access to officers of the
Trustee responsible for performing such duties. Upon request, the Trustee shall
furnish the Depositor, the Master Servicer, the NIMS Insurer and any requesting
Certificateholder with its most recent financial statements. The Trustee shall
cooperate fully with the Seller, the Originator the Master Servicer, the
Depositor and such Certificateholder and shall make available to the Seller, the
Originator, the Master Servicer, the Depositor, the NIMS Insurer

                                       127

<PAGE>

and such Certificateholder for review and copying such books, documents or
records as may be requested with respect to the Trustee's duties hereunder. The
Seller, the Originator, the Depositor, the Master Servicer and the
Certificateholders shall not have any responsibility or liability for any action
or failure to act by the Trustee and are not obligated to supervise the
performance of the Trustee under this Agreement or otherwise.

          SECTION 8.13. Suits for Enforcement.

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

          SECTION 8.14. Waiver of Bond Requirement.

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

          SECTION 8.15. Waiver of Inventory, Accounting and Appraisal
                        Requirement.

          The Trustee shall be relieved of, and each Certificateholder hereby

                              REMIC ADMINISTRATION

          SECTION 9.01. REMIC Administration.

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

          (b) The Closing Date is hereby designated as the "Startup Day" of each
REMIC within the meaning of section 860G(a)(9) of the Code.

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

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

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

                                       129

<PAGE>

          (f) The Trustee, the Master Servicer and the Holders of Certificates
shall take any action or cause the REMIC to take any action necessary to create
or maintain the status of each REMIC as a REMIC under the REMIC Provisions and
shall assist each other as necessary to create or maintain such status. Neither
the Trustee, the Master Servicer nor the Holder of any Residual Certificate
shall take any action, cause any REMIC created hereunder to take any action or
fail to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of such REMIC as a REMIC or (ii) result in the imposition of a tax upon
such REMIC (including but not limited to the tax on prohibited transactions as
defined in Code Section 860F(a)(2) and the tax on prohibited contributions set
forth on Section 860G(d) of the Code) (either such event, an "Adverse REMIC
Event") unless the Trustee, the NIMS Insurer and the Master Servicer have
received an Opinion of Counsel (at the expense of the party seeking to take such
action) to the effect that the contemplated action will not endanger such status
or result in the imposition of such a tax. In addition, prior to taking any
action with respect to any REMIC created hereunder or the assets therein, or
causing such REMIC to take any action, which is not expressly permitted under
the terms of this Agreement, any Holder of a Residual Certificate will consult
with the Trustee, the NIMS Insurer and the Master Servicer, or their respective
designees, in writing, with respect to whether such action could cause an
Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall
take any such action or cause any REMIC to take any such action as to which the
Trustee, the NIMS Insurer or the Master Servicer has advised it in writing that
an Adverse REMIC Event could occur.

          (g) Each Holder of a Residual Certificate shall pay when due any and
all taxes imposed on each REMIC created hereunder by federal or state
governmental authorities. To the extent that such Trust taxes are not paid by a
Residual Certificateholder, the Trustee shall pay any remaining REMIC taxes out
of current or future amounts otherwise distributable to the Holder of the
Residual Certificate in the REMICs or, if no such amounts are available, out of
other amounts held in the Distribution Account, and shall reduce amounts
otherwise payable to Holders of regular interests in the related REMIC. Subject
to the foregoing, in the event that a REMIC incurs a state or local tax,
including franchise taxes, as a result of a determination that such REMIC is
domiciled in the State of California for state tax purposes by virtue of the
location of the Master Servicer, the Master Servicer agrees to pay on behalf of
such REMIC when due, any and all state and local taxes imposed as a result of
such a determination, in the event that the Holder of the related Class R
Certificate fails to pay such taxes, if any, when imposed.

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

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

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

                                       130

<PAGE>

          (k) On or before April 15 of each calendar year beginning in 2002, the
Master Servicer shall deliver to the NIMS Insurer, the Trustee and each Rating
Agency an Officers' Certificate stating the Master Servicer's compliance with
the provisions of this Section 9.01.

          (j) The Trustee will apply for an Employee Identification Number from
the Internal Revenue Service via a Form SS-4 or other acceptable method for all
tax entities and shall complete the Form 8811.

          SECTION 9.02. Prohibited Transactions and Activities.

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

          SECTION 9.03. Indemnification with Respect to Certain Taxes and Loss
                        of REMIC Status.

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

                                       131

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

                                   TERMINATION

          SECTION 10.01. Termination.

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

          The Master Servicer (or if the Master Servicer fails to exercise such
option, the NIMS Insurer) may, at its option, terminate this Agreement on any
date on which the aggregate of the Principal Balances of the Mortgage Loans
(after giving effect to scheduled payments of principal due during the related
Due Period, to the extent received or advanced, and unscheduled collections of
principal received during the related Prepayment Period) on such date is equal
to or less than 10% of the sum of the aggregate Principal Balances of the
Initial Mortgage Loans on the Cut-off Date plus the Original Pre-Funded Amount,
by purchasing, on the next succeeding Distribution Date, all of the outstanding
Mortgage Loans and REO Properties at a price equal to the greater of the
Principal Balance of the Mortgage Loans and REO Properties (after giving effect
to scheduled payments of principal due during the related Due Period, to the
extent received or advanced, and unscheduled collections of principal received
during the related Prepayment Period) or the market value of the Mortgage Loans
and REO Properties, in each case plus accrued and unpaid interest thereon at the
weighted average of the Mortgage Rates through the end of the Due Period
preceding the final Distribution Date, plus unreimbursed Servicing Advances,
Advances, any unpaid Servicing Fees allocable to such Mortgage Loans and REO
Properties and any accrued and unpaid Net WAC Rate Carryover Amount (the
"Termination Price").

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

          Any such purchase shall be accomplished by deposit into the
Distribution Account on the Determination Date before such Distribution Date of
the Termination Price.

          (b) Notice of any termination, specifying the Distribution Date (which
shall be a date that would otherwise be a Distribution Date) upon which the
Certificateholders may surrender

                                       133

<PAGE>

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

          (c) Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to the Holders of the Certificates on the
Distribution Date for such final distribution, in proportion to the Percentage
Interests of their respective Class and to the extent that funds are available
for such purpose, an amount equal to the amount required to be distributed to
such Holders in accordance with the provisions of Section 4.01 for such
Distribution Date. By acceptance of the Class R Certificates, the Holders of the
Class R Certificates agree, in connection with any termination hereunder, to
assign and transfer any amounts in excess of the par value of the Mortgage
Loans, and to the extent received in respect of such termination, to pay any
such amounts to the Holders of the Class C Certificates.

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

          SECTION 10.02. Additional Termination Requirements.

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

                                       134

<PAGE>

          (i) Within 90 days prior to the final Distribution Date, the Master
     Servicer or the NIMS Insurer shall adopt and the Trustee shall sign a plan
     of complete liquidation of each REMIC created hereunder meeting the
     requirements of a "Qualified Liquidation" under Section 860F of the Code
     and any regulations thereunder; and

          (ii) At or after the time of adoption of such a plan of complete
     liquidation and at or prior to the final Distribution Date, the Trustee
     shall sell all of the assets of the Trust Fund to the Master Servicer or
     the NIMS Insurer, as applicable, for cash pursuant to the terms of the plan
     of complete liquidation.

          (b) By their acceptance of Certificates, the Holders thereof hereby
agree to appoint the Trustee as their attorney in fact to: (i) adopt such a plan
of complete liquidation (and the Certificateholders hereby appoint the Trustee
as their attorney in fact to sign such plan) as appropriate and (ii) to take
such other action in connection therewith as may be reasonably required to carry
out such plan of complete liquidation all in accordance with the terms hereof.

                            MISCELLANEOUS PROVISIONS

          SECTION 11.01. Amendment.

          This Agreement may be amended from time to time by the Depositor, the
Master Servicer and the Trustee with the consent of the NIMS Insurer and without
the consent of the Certificateholders (i) to cure any ambiguity, (ii) to correct
or supplement any provisions herein which may be defective or inconsistent with
any other provisions herein or (iii) to make any other provisions with respect
to matters or questions arising under this Agreement which shall not be
inconsistent with the provisions of this Agreement; PROVIDED, HOWEVER, that any
such action listed in clause (i) through (iii) above shall be deemed not to
adversely affect in any respect the interests of any Certificateholder, if
evidenced by (i) written notice to the Depositor, the Master Servicer and the
Trustee from the Rating Agencies that such action will not result in the
reduction or withdrawal of the rating of any outstanding Class of Certificates
with respect to which it is a Rating Agency or (ii) an Opinion of Counsel
delivered to the Master Servicer and the Trustee.

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

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

          Promptly after the execution of any such amendment the Trustee shall
furnish, at the expense of the Person that requested the amendment if such
Person is the Master Servicer (but in no event at the expense of the Trustee),
otherwise at the expense of the Trust, a copy of such

                                       136

<PAGE>

amendment and the Opinion of Counsel referred to in the immediately preceding
paragraph to the Master Servicer, the NIMS Insurer and each Rating Agency.

          It shall not be necessary for the consent of Certificateholders under
this Section 11.01 to approve the particular form of any proposed amendment;
instead it shall be sufficient if such consent shall approve the substance
thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trustee may prescribe.

          The Trustee may, but shall not be obligated to, enter into any
amendment pursuant to this Section 11.01 that affects its rights, duties and
immunities under this Agreement or otherwise.

          SECTION 11.02. Recordation of Agreement; Counterparts.

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

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

          SECTION 11.03. Limitation on Rights of Certificateholders.

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

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

          No Certificateholder shall have any right by virtue of any provision
of this Agreement to institute any suit, action or proceeding in equity or at
law upon or under or with respect to this Agreement, unless such Holder
previously shall have given to the Trustee a written notice of default and of
the continuance thereof, as hereinbefore provided, and unless also the Holders
of Certificates

                                       137

<PAGE>

entitled to at least 25% of the Voting Rights shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee for 15 days after its receipt of
such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding. It is understood and intended,
and expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue of any provision of this
Agreement to affect, disturb or prejudice the rights of the Holders of any other
of such Certificates, or to obtain or seek to obtain priority over or preference
to any other such Holder, which priority or preference is not otherwise provided
for herein, or to enforce any right under this Agreement, except in the manner
herein provided and for the equal, ratable and common benefit of all
Certificateholders. For the protection and enforcement of the provisions of this
Section 11.03 each and every Certificateholder and the Trustee shall be entitled
to such relief as can be given either at law or in equity.

          SECTION 11.04. Governing Law; Jurisdiction.

          This Agreement shall be construed in accordance with the laws of the
State of New York, and the obligations, rights and remedies of the parties
hereunder shall be determined in accordance with such laws. With respect to any
claim arising out of this Agreement, each party irrevocably submits to the
exclusive jurisdiction of the courts of the State of New York and the United
States District Court located in the Borough of Manhattan in The City of New
York, and each party irrevocably waives any objection which it may have at any
time to the laying of venue of any suit, action or proceeding arising out of or
relating hereto brought in any such courts, irrevocably waives any claim that
any such suit, action or proceeding brought in any such court has been brought
in any inconvenient forum and further irrevocably waives the right to object,
with respect to such claim, suit, action or proceeding brought in any such
court, that such court does not have jurisdiction over such party, provided that
service of process has been made by any lawful means.

          SECTION 11.05. Notices.

                           Asset-Backed Certificates,
                                  Series 2001-4

     This Certificate is one of a duly authorized issue of Certificates
designated as Option One Mortgage Loan Trust 2001-4, Asset-Backed Certificates,
Series 2001-4 (herein collectively called the "Certificates"), and representing
a beneficial ownership interest in the Trust created by the Agreement.

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

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

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

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

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

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

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

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

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

     On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amount, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in [month/year].

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

     The Certificateholder, by its acceptance of this Certificate, agrees that

payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

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

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

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

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

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

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

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

Certificate Registrar, any Paying Agent and any agent of the Master Servicer,
the Depositor, the Trustee, the NIMs Insurer, the Certificate Registrar, any

whose name any Certificate is registered as the owner hereof for all purposes,
and none of the Master Servicer, the Trust, the Trustee nor any agent of any of
them shall be affected by notice to the contrary.

     On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amount, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in [month/year].

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

     mortgage loans (the "Mortgage Loans")

            OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as Depositor

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

     This certifies that Option One Mortgage Securities Corp. is the registered
owner of the Percentage Interest evidenced by this Class C Certificate (obtained
by dividing the Denomination of this Class C Certificate by the Original Class
Certificate Principal Balance) in certain distributions with respect to a Trust
consisting primarily of the Mortgage Loans deposited by Option One Mortgage
Acceptance Corporation (the "Depositor"). The Trust was created pursuant to a
Pooling and Servicing Agreement dated as of October 1, 2001 (the "Agreement")
among the Depositor, Option One Mortgage Corporation, as master servicer (the
"Master Servicer"), and Wells Fargo Bank Minnesota, N.A., a national banking
association, as Trustee (the "Trustee"). To the extent not defined herein, the
capitalized terms used herein have the meanings assigned in the Agreement. This
Class C Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Class C
Certificate by virtue of the acceptance hereof assents and by which such Holder
is bound.

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

October 1, 2001 (the "Agreement") among the Depositor, Option One Mortgage
Corporation, as master servicer (the 'Master Servicer") and Wells Fargo Bank
Minnesota, N.A., a national banking association, as trustee (the "Trustee"). To

meanings assigned in the Agreement. This Certificate is issued under and is
subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of the acceptance hereof
assents and by which such Holder is bound.

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

     No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Depositor in writing the facts surrounding
the transfer. In the event that such a transfer is not to be made pursuant to
Rule 144A of the Act, there shall be delivered to the Trustee and the Depositor
an Opinion of Counsel that such transfer may be made pursuant to an exemption
from the Act, which Opinion of Counsel shall not be obtained at the expense of

Plan or any person using Plan Assets to acquire this Certificate shall be made
except in accordance with Section 5.02(d) of the Agreement.

     Each Holder of this Certificate will be deemed to have agreed to be bound
by the restrictions of the Agreement, including but not limited to the

the transferor, each of such documents to be in the form described in the
Agreement, (iii) each person holding or acquiring any Ownership Interest in this
Certificate must agree to require a transfer affidavit and to deliver a transfer
certificate to the Trustee as required pursuant to the Agreement, (iv) each
person holding or acquiring an Ownership Interest in this Certificate must agree
not to transfer an Ownership Interest in this Certificate if it has actual
knowledge that the proposed transferee is not a Permitted Transferee and (v) any
attempted or purported transfer of any Ownership Interest in this Certificate in
violation of such restrictions will be absolutely null and void and will vest no
rights in the purported transferee. Pursuant to the Agreement, the Trustee will
provide the Internal Revenue Service and any pertinent persons with the
information needed to compute the tax imposed under the applicable tax laws on
transfers of residual interests to disqualified organizations, if any person
other than a Permitted Transferee acquires an Ownership Interest on a Class R
Certificate in violation of the restrictions mentioned above.

Certificate set forth on the reverse hereof, which further provisions shall for

certified by the applicable public recording office to be a true and complete
copy of the original. If the original lender's title insurance policy, or a
certified copy thereof, was not delivered pursuant to Section 2.02(v) above, the

Servicing Agreement.

          The Purchaser hereby acknowledges its acceptance of all right, title
and interest to the Mortgage Loans and other property, now existing and
hereafter created, conveyed to it pursuant to Section 2.01.

          The parties hereto intend that the transaction set forth herein be a
sale by the Seller to the Purchaser of all the Seller's right, title and
interest in and to the Mortgage Loans and other property described above. In the
event the transaction set forth herein is deemed not to be a sale, the Seller
hereby grants to the Purchaser a security interest in all of the Seller's right,
title and interest in, to and under the Mortgage Loans and other property
described above, whether now existing or hereafter created, to secure all of the
Seller's obligations hereunder; and this Agreement shall constitute a security
agreement under applicable law.

          The Seller shall cause the Assignments which were delivered in blank
to be completed and shall cause all Assignments referred to in Section 2.02(iii)
hereof and, to the extent necessary, in Section 2.02(iv) hereof to be recorded;
PROVIDED, HOWEVER, the Seller need not cause to be recorded any Assignment which
relates to a Mortgage Loan in any jurisdiction under the laws of which, as
evidenced by an Opinion of Counsel delivered by the Seller to the NIMs Insurer,
the Trustee and the Rating Agencies on or before the Closing Date, the
recordation of such assignment is not necessary to protect the Trustee's
interest in the related Mortgage Loan; PROVIDED, HOWEVER, notwithstanding the
delivery of any Opinion of Counsel, each Assignment shall be submitted for
recording by the Seller in the manner described above, at no expense to the
Trust Fund or Trustee, upon the earliest to occur of: (i) reasonable direction
by Holders of Certificates entitled to at least 25% of the Voting Rights, (ii)
the occurrence of a Master Servicer Event of Termination, (iii) the occurrence
of a bankruptcy, insolvency or foreclosure relating to the Master Servicer, (iv)
the occurrence of a servicing transfer as described in Section 7.02 in the
Pooling and Servicing Agreement, (v) if the Seller is not the Master Servicer
and with respect to any one Assignment the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Mortgagor under the related Mortgage
and (vi) any Mortgage Loan that is 90 days or more Delinquent. The Seller shall
be required to deliver such assignments for recording within 45 days of the
Closing Date. The Seller shall furnish the Trustee,

                                        4

<PAGE>

or its designated agent, with a copy of each Assignment submitted for recording.
In the event that any such Assignment is lost or returned unrecorded because of
a defect therein, the Seller shall promptly have a substitute Assignment
prepared or have such defect cured, as the case may be, and thereafter cause
each such Assignment to be duly recorded. In the event that any Mortgage Note is
endorsed in blank as of the Closing Date, promptly following the Closing Date
the Depositor shall cause to be completed such endorsements "Pay to the order of
Wells Fargo Bank Minnesota, N.A.,
as Trustee, without recourse."

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

          Section 2.03      PAYMENT OF PURCHASE PRICE FOR THE MORTGAGE LOANS.

          In consideration of the sale of the Mortgage Loans from the Seller to
the Purchaser on the Closing Date, the Purchaser agrees to pay to the Seller on
the Closing Date (the "Purchase Price") by transfer of (i) immediately available
funds in an amount equal to $21,264,148.60 and (ii) a 6.29% percentage interest

delivered to the originator of the Mortgage Loan and referred to in the
appraisal made in connection with the origination of the related Mortgage Loan,
(iii) other matters to which like properties are commonly subject which do not
materially interfere with the benefits of the security intended to be provided
by such Mortgage and (iv) the first lien on the Mortgaged Property, in the case
of the Mortgages that are second liens;

                   (h) Any security agreement, chattel mortgage or equivalent
document related to such Mortgage Loan establishes and creates a valid and
enforceable first or second lien on the Mortgaged Property;

<PAGE>

                   (i) As of the last calendar day of September 2001 and with
respect to any Mortgage Loan that had a payment due on or before September 1,
2001, except with respect to 12.65% of the Initial Mortgage Loans by the
aggregate Cut-off Date Principal Balance of the Initial Mortgage Loans, the
related Monthly Payment due on September 1, 2001 has been received. In addition,
3.71% of the Initial Mortgage Loans have been 30 or more days delinquent in the
last 12 months and 0.98% of the Initial Mortgage Loans have been 30 or more days
delinquent for two payment periods in the last 12 months;

                   (j) The Seller 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 under the
Mortgage Loan;

                   (k) The Seller has not impaired, waived, altered or modified
the related Mortgage or Mortgage Note in any material respect, or satisfied,
canceled, rescinded or subordinated such Mortgage or Mortgage Note in whole or
in part or released all or any material portion of the Mortgaged Property from
the lien of the Mortgage, or executed any instrument of release, cancellation,
rescission or satisfaction of the Mortgage Note or Mortgage;

                   (l) As of the Cut-off Date, the Mortgage has not been
satisfied, canceled or subordinated, in whole or in part, or rescinded, and the
Mortgaged Property has not been released from the lien of the Mortgage, in whole
or in part (except for a release that does not materially impair the security of
the Mortgage Loan or a release the effect of which is reflected in the
Loan-to-Value Ratio for the Mortgage Loan as set forth in the Schedule of
Mortgage Loans), nor has any instrument been executed that would effect any such
release, cancellation, subordination or rescission;

                   (m) No Mortgage Loan is subject to any right of rescission,
set-off, counterclaim or defense, including the defense of usury, nor will the
operation of any of the terms of any Mortgage Note or Mortgage, or the exercise
of any right thereunder, render either the Mortgage Note or the Mortgage
unenforceable in whole or in part, or subject to any right of rescission,
set-off, counterclaim or defense, including the defense of usury, and no such
right of rescission, set-off, counterclaim or defense has been asserted with
respect thereto;

                   (n) To the Seller's knowledge, there is no proceeding pending
for the total or partial condemnation and no eminent domain proceedings pending
affecting any Mortgaged Property;

                   (o) Each Mortgage Loan is covered by either (i) a mortgage
title insurance policy or other generally acceptable form of insurance policy
customary in the jurisdiction where the Mortgaged Property is located or (ii) if
generally acceptable in the jurisdiction where the Mortgaged Property is
located, an attorney's opinion of title given by an attorney licensed to
practice law in the jurisdiction where the Mortgaged Property is located. All of
the Seller's rights under such policies, opinions or other instruments shall be
transferred and assigned to Purchaser upon sale and assignment of the Mortgage
Loans hereunder. The title insurance policy has been issued by a title insurer
licensed to do business in the jurisdiction where the Mortgaged Property is
located, insuring the original lender, its successor and assigns, as to the
first or second priority lien of the Mortgage in the original principal amount
of the Mortgage Loan, subject to the exceptions contained in such

                                        7

<PAGE>

policy. The Seller is the sole insured of such mortgagee title insurance policy,
and such mortgagee title insurance policy is in full force and effect and will
be in force and effect upon the consummation of the transactions contemplated by
this Agreement. Neither the Seller nor any affiliate of the Seller has made, and
the Seller has no knowledge of, any claims under such mortgagee title insurance
policy. The Seller is not aware of any action by a prior holder and neither the
Seller nor any affiliate of the Seller has done, by act or omission, anything
which could impair the coverage or enforceability of such mortgagee title
insurance policy or the accuracy of such attorney's opinion of title;

                   (p) There is no material default, breach, violation or event
of acceleration existing under the related Mortgage or the related Mortgage Note
and no event which, with the passage of time or with notice and the expiration
of any grace or cure period, would constitute a material default, breach,
violation or event of acceleration, other than a payment delinquency that is for
a payment due after the date specified in (i) above. Neither the Seller nor any
affiliate of the Seller has waived any default, breach, violation or event of
acceleration;

                   (q) With respect to any Mortgage Loan which provides for an
adjustable interest rate, all rate adjustments have been performed in accordance
with the terms of the related Mortgage Note or subsequent modifications, if any;

                   (r) To the Seller's knowledge, there are no delinquent taxes,
ground rents, water charges, sewer rents, assessments, insurance premiums,
leasehold payments, including assessments payable in future installments or
other outstanding charges, affecting the related Mortgaged Property;

                   (s) No foreclosure proceedings are pending against the
Mortgaged Property and the Mortgage Loan is not subject to any pending
bankruptcy or insolvency proceeding, and to the Seller's best knowledge, no
material litigation or lawsuit relating to the Mortgage Loan is pending;

                   (t) The Mortgage Loan obligates the mortgagor thereunder to
maintain a hazard insurance policy ("Hazard Insurance") in an amount at least
equal to the lesser of (i) the maximum insurable value of such improvements or
(ii) the principal balance of the Mortgage Loan with a standard mortgagee
clause, in either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance, and, if applicable, flood insurance policy at the
Mortgagor's cost and expense, and on the Mortgagor's failure to do so,
authorizes the holder of the Mortgage to obtain and maintain such insurance at
the Mortgagor's cost and expense, and to seek reimbursement therefor from the
Mortgagor. The Mortgaged Property is covered by Hazard Insurance;

                   (u) The Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

                                        8

<PAGE>

                   (v) The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage Loan
in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
customary and enforceable provisions such as to render the rights and remedies
of the holder thereof adequate for the realization against the Mortgaged
Property of the benefits of the security provided thereby, including (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale or judicial
foreclosure and (ii) otherwise by judicial foreclosure. Since the date of
origination of the Mortgage Loan, the Mortgaged Property has not been subject to
any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not
filed for protection under applicable bankruptcy laws. There is no homestead or
other exemption available to the Mortgagor that would interfere with the right
to sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage. In the event the Mortgage constitutes a deed of trust, a trustee, duly
qualified under applicable law to serve as such, as been properly designated and
currently so serves and is named in the Mortgage, and no fees or expenses are or
will become payable by Purchaser to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Seller or any affiliate of the Seller and the
Seller has no knowledge of any relief requested or allowed to the Mortgagor
under the Soldiers and Sailors Civil Relief Act of 1940;

                   (w) Except as set forth in the appraisal which forms part of
the related Mortgage File, the Mortgaged Property, normal wear and tear
excepted, is undamaged by waste, fire, earthquake or earth movement, windstorm,
flood, tornado or other casualty so as to affect materially and adversely the
value of the Mortgaged Property as security for the Mortgage Loan or the use for
which the premises were intended;

                   (x) To the Seller's knowledge, there was no fraud involved in
the origination of the Mortgage Loan by the mortgagee or by the Mortgagor, any
appraiser or any other party involved in the origination of the Mortgage Loan;

                   (y) Each Mortgage File contains an appraisal of the Mortgaged
Property indicating an appraised value equal to the appraised value identified
for such Mortgaged Property on the Mortgage Loan Schedule. Each appraisal has
been performed in accordance with the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989;

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

                   (aa) No improvements on the related Mortgaged Property (upon
which value was given) encroach on adjoining properties (and in the case of a
condominium unit, such improvements are within the project with respect to that
unit), and no improvements on adjoining properties encroach upon the Mortgaged
Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

                                        9

<PAGE>

                   (bb) Each Mortgage Loan was originated or acquired by a
savings and loan association, a savings bank, a commercial bank or similar
banking institution which is supervised and examined by a federal or state
authority, or by a mortgagee approved by the Secretary of HUD. Each Mortgage
Loan was originated substantially in accordance with the Seller's underwriting
criteria, which are at least as stringent as the underwriting criteria set forth
in the Prospectus Supplement. Each Mortgage Loan is currently being serviced by
the Seller and has been serviced by the Seller since the date of origination of
such Mortgage Loan;

                   (cc) (i) Principal payments on the Mortgage Loan commenced no
more than two months after the proceeds of the Mortgage Loan were disbursed and
(ii) each Mortgage Note is payable on the first day of each month;

                   (dd) Other than with respect to not more than 6.26% of the
Initial Mortgage Loans (by aggregate principal balance of the Initial Mortgage
Loans as of the Cut-off Date), which are "balloon payment" mortgage loans, each
Initial Mortgage Loan is fully amortizing;

                   (ee) The Mortgage Loan bears interest at the Mortgage Rate
and the Mortgage Note does not permit negative amortization. No Mortgage Loan
bearing interest at an adjustable rate permits the Mortgagor to convert the
Mortgage Loan to a fixed rate Mortgage Loan;

                   (ff) With respect to escrow deposits, if any, all such
payments are in the possession of, or under the control of, the Master Servicer
and there exist no deficiencies in connection therewith for which customary
arrangements for repayment thereof have not been made. No escrow deposits or
escrow advances or other charges or payments due the Master Servicer have been
capitalized under any Mortgage or the related Mortgage Note;

                   (gg) No Mortgage Loan contains provisions pursuant to which
scheduled payments are: (i) paid or partially paid with funds deposited in any
separate account established by the Seller, the Mortgagor, or anyone on behalf
of the Mortgagor; or (ii) paid by any source other than the Mortgagor or
contains any other similar provisions which may constitute a "buydown"
provision. The Mortgage Loan is not a graduated payment mortgage loan and the
Mortgage Loan does not have a shared appreciation or other contingent interest
feature;

                   (hh) As of the  origination  date of each Mortgage  Loan, the
related Mortgaged Property is lawfully permitted to be occupied under applicable
law;

                   (ii) No law relating to servicing, collection or notification
practices and no law relating to origination practices, has been violated in
connection with any Mortgage Loan transferred to the Purchaser pursuant to this
Agreement, including, without limitation, usury, truth in lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws. The Mortgage Loan has been serviced in accordance with the
terms of the Mortgage Note;

                   (jj) No Mortgage Loan was made in connection with (a) the
construction or rehabilitation of a Mortgaged Property or (b) facilitating the
trade-in or exchange of a Mortgaged Property;

                                       10

<PAGE>

                   (kk) The proceeds of the Mortgage Loan have been fully
disbursed to or for the account of the Mortgagor and there is no obligation for
the Mortgagee to advance additional funds thereunder, and any and all
requirements as to completion of any on-site or off-site improvement and as to
disbursements of any escrow funds therefor have been complied with. All costs,
fees and expenses incurred in making or closing the Mortgage Loan and the
recording of the Mortgage have been paid, and the Mortgagor is not entitled to
any refund of any amounts paid or due to the, Mortgagee pursuant to the Mortgage
Note or Mortgage;

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

                   (mm) As to each Mortgage Loan,  interest is calculated on the
Mortgage Note on the basis of twelve 30-day months and a 360 day year;

                   (nn) The Mortgaged Property consists of one of the following:
detached or semi-detached one- to four-family dwelling units, townhouses,
individual condominium units and individual units in planned unit developments,
or manufactured homes;

                   (oo) Each Mortgage Loan constitutes a "qualified mortgage"
within the meaning of Section 860G(a)(3) of the Code;

                   (pp) The Mortgage  Loans were not  intentionally  selected by
the Seller in a manner intended to adversely affect the Purchaser or the Trust;

                   (qq) The representations, warranties and covenants, set forth
in this Section shall survive the Closing Date;

                   (rr) The Mortgage Loans have original terms to maturity
ranging from 15 to 30 years;

                   (ss) With respect to the Mortgage Loans, no more than 9.94%;
8.44%; 7.15% and 7.13% of the Initial Mortgage Loans, by Cut-off Date Principal
Balance will be secured by Mortgaged Properties located in California, Illinois,
New York, Massachusetts, respectively; and 77.15% of the Initial Mortgage Loans,
by Cut-off Date Principal Balance will be secured by real property with a single
family residence erected thereon and approximately 1.89% of the Initial Mortgage
Loans, by the Cut-off Date Principal Balance are secured by condominiums;

                   (tt)  As of  the  Cut-off  Date,  each  Mortgage  Loan  had a
Loan-to-Value-Ratio that was less than or equal to 100.00%;

                   (uu) With respect to each Mortgage Loan, the Mortgage Note
related thereto bears a fixed Mortgage Rate or an adjustable Mortgage Rate which
will be adjusted on each Adjustment Date to equal the Index plus the Gross
Margin, rounded to the nearest or next highest 0.125%, subject to the Periodic
Rate Cap, the Maximum Mortgage Rate and the Minimum Mortgage Rate;

                                       11

<PAGE>

                   (vv)  The  average  Cut-off  Date  Principal  Balance  of the
Initial Mortgage Loans is $118,134.66;

                   (ww) No Mortgage Loan is subject to the requirements of the
Home Ownership and Equity Protection Act of 1994 ("HOEPA") and no Mortgage Loan
is in violation of any state law or ordinance similar to HOEPA;

                   (xx) Each Mortgage Loan conforms, and all Mortgage Loans in
the aggregate conform, in all material respects, to the description thereof set
forth in the Prospectus Supplement;

                   (yy) With respect to second lien Mortgage Loans, either (a)
no consent for the Mortgage Loan is required by the holder of the related first
lien or (b) such consent has been obtained and is contained in the Mortgage
File; and

                   (zz) Each Mortgage Note is comprised of one original
promissory note and each such promissory note constitutes an "instrument" for
purposes of section 9-102(a)(65) of the UCC.

          Section 3.02 SELLER REPRESENTATIONS AND WARRANTIES RELATING TO THE
SELLER. The Seller represents, warrants and covenants to the Purchaser as of the
Closing Date or as of such other date specifically provided herein or in the
applicable Assignment and Conveyance:

                   (i) The Seller is duly organized, validly existing and in

Property is located to the extent necessary to ensure the enforceability of each
Mortgage Loan in accordance with the terms of this Agreement;

                   (ii) The Seller has the full power and authority to hold each

of the sale of each Mortgage Loan by the Seller, the Seller had the full power
and authority to hold each Mortgage Loan and to sell each Mortgage Loan;

                   (iii) The  execution  and  delivery of this  Agreement by the
Seller and the  performance of and  compliance  with the terms of this Agreement
will not violate the Seller's articles of incorporation or by-laws or constitute

applicable to the Seller or its assets;

                   (iv) The Seller is not in violation of, and the execution and
delivery of this Agreement by the Seller and its performance and compliance with

                                       12

<PAGE>

assets, which violation might have consequences that would materially and
adversely affect the condition (financial or otherwise) or the operation of the
Seller or its assets or might have consequences that would materially and
adversely affect the performance of its obligations and duties hereunder;

                   (v) The Seller is a HUD approved mortgagee pursuant to
Section 203 and Section 211 of the National Housing Act. No event has occurred,
including but not limited to a change in insurance coverage, which would make
the Seller unable to comply with HUD eligibility requirements or which would
require notification to HUD;

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

                   (vii) There are no actions or proceedings against, or
investigations known to it of, the Seller before any court, administrative or
other tribunal (A) that might prohibit its entering into this Agreement, (B)
seeking to prevent the sale of the Mortgage Loans or the consummation of the

under, or validity of enforceability of, this Agreement;

                   (viii) No consent, approval, authorization or order of any
court or governmental agency or body is required for the execution, delivery and
performance by the Seller of, or compliance by the Seller with, this Agreement
or the consummation of the transactions contemplated by this Agreement, except
for such consents, approvals, authorizations or orders, if any, that have been
obtained;

                   (ix) The consummation of the transactions contemplated by

                   (x) The information delivered by the Seller to the Purchaser
with respect to the Seller's loan loss, foreclosure and delinquency experience
on mortgage loans underwritten to similar standards as the Mortgage Loans and
covering mortgaged properties similar to the Mortgaged Properties, is true and
correct in all material respects as of the date of such report;

                   (xi) Except with respect to any statement regarding the
intentions of the Purchaser, or any other statement contained herein the truth
or falsity of which is dependant solely upon the actions of the Purchaser, this
Agreement does not contain any untrue statement of material fact or omit to
state a material fact necessary to make the statements contained herein not
misleading. The written statements, reports and other documents prepared and
furnished or to be prepared and furnished by the Seller pursuant to this
Agreement or in connection with the transactions contemplated hereby taken in
the aggregate do not contain any untrue statement of material fact or omit to
state a material fact necessary to make the statements contained therein not
misleading; and

                                       13

<PAGE>

                   (xii) The Seller has not transferred the Mortgage Loans with
any intent to hinder, delay or defraud any of its creditors.

          Section 3.03 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It
is understood and agreed that the representations and warranties set forth in
Sections 3.01 and 3.02 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and warranties contained herein that are made to the knowledge
or the best knowledge of the Seller or as to which the Seller has no knowledge,
if it is discovered that the substance of any such representation and warranty
is inaccurate and the inaccuracy materially and adversely affects the value of
the related Mortgage Loan, or the interest therein of the Purchaser or the
Purchaser's assignee, designee or transferee, then notwithstanding the Seller's
lack of knowledge with respect to the substance of such representation and
warranty being inaccurate at the time the representation and warranty was made,
such inaccuracy shall be deemed a breach of the applicable representation and
warranty and the Seller shall take such action described in the following
paragraphs of this Section 3.03 in respect of such Mortgage Loan. Upon discovery
by either the Seller, the Master Servicer or the Purchaser of a breach of any of
the foregoing representations and warranties that materially and adversely
affects the value of the Mortgage Loans or the interest of the Purchaser (or
which materially and adversely affects the interests of the Purchaser in the
related Mortgage Loan in the case of a representation and warranty relating to a
particular Mortgage Loan), the party discovering such breach shall give prompt
written notice to the others.

          Within 90 days of the earlier of either discovery by or notice to the
Seller of any breach of a representation or warranty made by the Seller that
materially and adversely affects the value of a Mortgage Loan or the Mortgage
Loans or the interest therein of the Purchaser, the Seller shall use its best
efforts promptly to cure such breach in all material respects and, if such
breach cannot be cured, the Seller shall, at the Purchaser's option, repurchase
such Mortgage Loan at the Purchase Price. In the event that a breach shall
involve any representation or warranty set forth in Section 3.02 and such breach
cannot be cured within 90 days of the earlier of either discovery by or notice
to the Seller of such breach, all of the Mortgage Loans shall, at the
Purchaser's option, be repurchased by the Seller at the Purchase Price. The
Seller may, at the request of the Purchaser and assuming the Seller has a
Qualified Substitute Mortgage Loan, rather than repurchase a deficient Mortgage
Loan as provided above, remove such Mortgage Loan and substitute in its place a
Qualified Substitute Mortgage Loan or Loans. If the Seller does not provide a
Qualified Substitute Mortgage Loan or Loans, it shall repurchase the deficient
Mortgage Loan. Any repurchase of a Mortgage Loan(s) pursuant to the foregoing
provisions of this Section 3.03 shall occur on a date designated by the
Purchaser and shall be accomplished by deposit in accordance with Section 2.03
of the Pooling and Servicing Agreement. Any repurchase or substitution required
by this Section shall be made in a manner consistent with Section 2.03 of the
Pooling and Servicing Agreement.

          At the time of substitution or repurchase of any deficient Mortgage
Loan, the Purchaser and the Seller shall arrange for the reassignment of the
repurchased or substituted Mortgage Loan to the Seller and the delivery to the
Seller of any documents held by the Trustee relating to the deficient or
repurchased Mortgage Loan. In the event the Purchase Price is deposited in the
Collection Account, the Seller shall, simultaneously with such deposit, give
written notice to the Purchaser that

                                       14

<PAGE>

such deposit has taken place. Upon such repurchase, the Mortgage Loan Schedule
shall be amended to reflect the withdrawal of the repurchased Mortgage Loan from
this Agreement.

          As to any Deleted Mortgage Loan for which the Seller substitutes a
Qualified Substitute Mortgage Loan or Loans, the Seller shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling and Servicing Agreement, with the Mortgage Note endorsed as required
therein. The Seller shall deposit in the Collection Account the Monthly Payment
less the Servicing Fee due on such Qualified Substitute Mortgage Loan or Loans
in the month following the date of such substitution. Monthly Payments due with
respect to Qualified Substitute Mortgage Loans in the month of substitution will
be retained by the Seller. For the month of substitution, distributions to the
Purchaser will include the Monthly Payment due on such Deleted Mortgage Loan in
the month of substitution, and the Seller shall thereafter be entitled to retain
all amounts subsequently received by the Seller in respect of such Deleted
Mortgage Loan. Upon such substitution, the Qualified Substitute Mortgage Loans
shall be subject to the terms of this Agreement in all respects, and the Seller
shall be deemed to have made with respect to such Qualified Substitute Mortgage
Loan or Loans as of the date of substitution, the covenants, representations and
warranties set forth in Sections 3.01 and 3.02.

          It is understood and agreed that the representations and warranties
set forth in Section 3.01 shall survive delivery of the respective Mortgage
Files to the Trustee on behalf of the Purchaser.

          It is understood and agreed that the obligations of the Seller set
forth in Section 3.03 to cure, repurchase and substitute for a defective
Mortgage Loan and to indemnify the Purchaser as provided in Section 5.01
constitute the sole remedies of the Purchaser respecting a missing or defective
document or a breach of the representations and warranties contained in Section
3.01 or 3.02.

                               SELLER'S COVENANTS

          Section 4.01 COVENANTS OF THE SELLER. The Seller hereby covenants that
except for the transfer hereunder, the Seller will not sell, pledge, assign or
transfer to any other Person, or grant, create, incur, assume or suffer to exist
any Lien on any Mortgage Loan, or any interest therein; the Seller will notify
the Trustee, as assignee of the Purchaser, of the existence of any Lien on any
Mortgage Loan immediately upon discovery thereof, and the Seller will defend the
right, title and interest of the Trust, as assignee of the Purchaser, in, to and
under the Mortgage Loans, against all claims of third parties claiming through
or under the Seller or the Seller; provided, however, that nothing in this
Section 4.01 shall prevent or be deemed to prohibit the Seller from suffering to
exist upon any of the Mortgage Loans any Liens for municipal or other local
taxes and other governmental charges if such taxes or governmental charges shall
not at the time be due and payable or if the Seller shall currently be
contesting the validity thereof in good faith by appropriate proceedings and
shall have set aside on its books adequate reserves with respect thereto.

               INDEMNIFICATION WITH RESPECT TO THE MORTGAGE LOANS

          Section 5.01      INDEMNIFICATION.

                   (a) The Seller agrees to indemnify and hold harmless the
Purchaser, each of its directors, each of its officers and each person or entity
who controls the Purchaser or any such person, within the meaning of Section 15
of the Securities Act, against any and all losses, claims, damages or
liabilities, joint and several, as incurred, to which the Purchaser, or any such
person or entity may become subject, under the Securities Act or otherwise, and
will reimburse the Purchaser, each such director and officer and each such
controlling person for any legal or other expenses incurred by the Purchaser or
such controlling person in connection with investigating or defending any such
losses, claims, damages or liabilities, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Seller or the omission or the
alleged omission to state therein a material fact necessary in order to make the
statements in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Seller, in the light of the
circumstances under which they were made, not misleading, but only to the extent
that such untrue statement or alleged untrue statement or omission or alleged
omission relates to the Seller Information contained in the Prospectus
Supplement, (ii) any untrue statement or alleged untrue statement of any
material fact contained in the information on any computer tape furnished to the
Purchaser or an affiliate thereof by or on behalf of the Seller containing
information regarding the assets of the Trust or (iii) any untrue statement or
alleged untrue statement of any material fact contained in any information
provided by the Seller to the Purchaser or any affiliate thereof, or any
material omission from the information purported to be provided hereby, and
disseminated to PricewaterhouseCoopers LLP or prospective investors (directly or
indirectly through available information systems) in connection with the
issuance, marketing or offering of the Certificates. This indemnity agreement
will be in addition to any liability which the Seller may otherwise have.

                   (b) The Purchaser agrees to indemnify and hold harmless the
Seller, its officers, directors and each person or entity who controls the
Seller, or any such person, against any and all losses, claims, damages or
liabilities, joint and several, to which the Seller or any such person or entity
may become subject, under the Securities Act or otherwise, and will reimburse
the Seller for any legal or other expenses incurred by the Seller, each officer
and director and controlling person in connection with investigating or
defending any such losses, claims, damages or liabilities insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the Prospectus Supplement or any amendment or
supplement to the Prospectus Supplement or the omission or the alleged omission
to state therein a material fact necessary in order to make the statements in
the Prospectus Supplement or any amendment or supplement to the Prospectus
Supplement, in the light of the circumstances under which they were made, not
misleading, but only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission is not contained in the Seller
Information in the Prospectus Supplement. This indemnity agreement will be in
addition to any liability which the Purchaser may otherwise have.

                                       16

<PAGE>

                   (c) Promptly after receipt by any indemnified party under
this Article V of notice of any claim or the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article V.

          If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Article V for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation.

          Any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article V consist of the Purchaser or by the Seller, if the
indemnified parties in this Article V consist of the Seller.

          Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to consent to a settlement of any action, the indemnifying
party agrees that it shall be liable for any settlement

                                       17

<PAGE>

of any proceeding effected without its written consent if such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and the indemnifying party has not previously provided the
indemnified party with written notice of its objection to such settlement. No
indemnifying party shall effect any settlement of any pending or threatened
proceeding in respect of which an indemnified party is or could have been a
party and indemnity is or could have been sought hereunder, without the written
consent of such indemnified party, unless settlement includes an unconditional
release of such indemnified party from all liability and claims that are the
subject matter of such proceeding.

                   (d) In order to provide for just and equitable contribution
in circumstances in which the indemnity agreement provided for in this Article
is for any reason held to be unenforceable although applicable in accordance
with its terms, the Seller, on the one hand, and the Purchaser, on the other,
shall contribute to the aggregate losses, liabilities, claims, damages and
expenses of the nature contemplated by said indemnity agreement incurred by the
Seller and the Purchaser in such proportions as shall be appropriate to reflect
the relative benefits received by the Seller on the one hand and the Purchaser
on the other from the sale of the Mortgage Loans such that the Purchaser is
responsible for the lesser of (i) 0.25% thereof and (ii) 0.25% of the aggregate
proceeds to the Seller from the sale of the Mortgage Loans and the Seller shall
be responsible for the balance; PROVIDED, HOWEVER, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section, each
officer and director of the Purchaser and each person, if any, who controls the
Purchaser within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Purchaser and each director of the Seller,
each officer of the Seller, and each person, if any, who controls the Seller
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Seller.

                   (e) The Seller agrees to indemnify and to hold each of the
Purchaser, the Trustee, each of the officers and directors of each such entity
and each person or entity who controls each such entity or person and each
Certificateholder harmless against any and all claims, losses, penalties, fines,
forfeitures, legal fees and related costs, judgments, and any other costs, fees
and expenses that the Purchaser, the Trustee, or any such person or entity and
any Certificateholder may sustain in any way (i) related to the failure of the
Seller to perform its duties in compliance with the terms of this Agreement,
(ii) arising from a breach by the Seller of its representations and warranties
in Section 3.01 or 3.02 of this Agreement or (iii) related to the origination or
prior servicing of the Mortgage Loans by reason of any acts, omissions, or
alleged acts or omissions of the Seller or any servicer. The Seller shall
immediately notify the Purchaser, the Trustee and each Certificateholder if a
claim is made by a third party with respect to this Agreement. The Seller shall
assume the defense of any such claim and pay all expenses in connection
therewith, including reasonable counsel fees, and promptly pay, discharge and
satisfy any judgment or decree which may be entered against the Purchaser, the
Trustee or any such person or entity and/or any Certificateholder in respect of
such claim.

                                   ARTICLE VI.

                                   TERMINATION

<PAGE>

          Section 6.01 TERMINATION. The respective obligations and
responsibilities of the Seller and the Purchaser created hereby shall terminate,

Agreement.

                                  ARTICLE VII.

                            MISCELLANEOUS PROVISIONS

          Section 7.01 AMENDMENT. This Agreement may be amended from time to
time by the Seller and the Purchaser, by written agreement signed by the Seller
and the Purchaser.

          Section 7.02 GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York and the
obligations, rights and remedies of the parties hereunder shall be determined in
accordance with such laws.

          Section 7.03 NOTICES. All demands, notices and communications
hereunder shall be in writing and shall be deemed to have been duly given if
personally delivered at or mailed by registered mail, postage prepaid, addressed
as follows:

          if to the Seller:

                   Option One Mortgage Corporation
                   3 Ada
                   Irvine, CA 92618
                   Attention: William L. O'Neill

or such other address as may hereafter be furnished to the Purchaser in writing
by the Seller.

          if to the Purchaser:

                   Option One Mortgage Acceptance Corporation
                   3 Ada
                   Irvine, CA 92618
                   Attention: William L. O'Neill

or such other address as may hereafter be furnished to the Seller in writing by
the Purchaser.

          Section 7.04 SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions of terms of this Agreement shall be held

enforceability of the other provisions of this Agreement.

                                       19

<PAGE>

          Section 7.05 COUNTERPARTS. This Agreement may be executed in one or
more counterparts and by the different parties hereto on separate counterparts,
each of which, when so executed, shall be deemed to be an original and such
counterparts, together, shall constitute one and the same agreement.

          Section 7.06 FURTHER AGREEMENTS. The Purchaser and the Seller each
agree to execute and deliver to the other such additional documents, instruments
or agreements as may be necessary or reasonable and appropriate to effectuate
the purposes of this Agreement or in connection with the issuance of any series
of Certificates representing interests in the Mortgage Loans.

          Without limiting the generality of the foregoing, as a further
inducement for the Purchaser to purchase the Mortgage Loans from the Seller, the
Seller will cooperate with the Purchaser in connection with the sale of any of
the securities representing interests in the Mortgage Loans. In that connection,
the Seller will provide to the Purchaser any and all information and appropriate
verification of information, whether through letters of its auditors and counsel
or otherwise, as the Purchaser shall reasonably request and will provide to the
Purchaser such additional representations and warranties, covenants, opinions of
counsel, letters from auditors, and certificates of public officials or officers
of the Seller as are reasonably required in connection with such transactions
and the offering of investment grade securities rated by the Rating Agencies.

          Section 7.07 INTENTION OF THE PARTIES. It is the intention of the
parties that the Purchaser is purchasing, and the Seller is selling, the
Mortgage Loans rather than pledging the Mortgage Loans to secure a loan by the
Purchaser to the Seller. Accordingly, the parties hereto each intend to treat
the transaction for federal income tax purposes and all other purposes as a sale
by the Seller, and a purchase by the Purchaser, of the Mortgage Loans. The
Purchaser will have the right to review the Mortgage Loans and the related
Mortgage Files to determine the characteristics of the Mortgage Loans which will
affect the federal income tax consequences of owning the Mortgage Loans and the
Seller will cooperate with all reasonable requests made by the Purchaser in the
course of such review.

         Section 7.08 SUCCESSORS AND ASSIGNS, ASSIGNMENT OF PURCHASE AGREEMENT.
This Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Purchaser, the Trustee and the NIMs Insurer. The NIMs Insurer shall
be a third party beneficiary hereof and may enforce the terms hereof as if a
party hereto. The obligations of the Seller under this Agreement cannot be
assigned or delegated to a third party without the consent of the Purchaser
which consent shall be at the Purchaser's sole discretion, except that the
Purchaser acknowledges and agrees that the Seller may assign its obligations
hereunder to any Person into which the Seller is merged or any corporation
resulting from any merger, conversion or consolidation to which the Seller is a
party or any Person succeeding to the business of the Seller. The parties hereto
acknowledge that the Purchaser is acquiring the Mortgage Loans for the purpose
of contributing them to a trust that will issue a series of Certificates
representing undivided interests in such Mortgage Loans. As an inducement to the
Purchaser to purchase the Mortgage Loans, the Seller acknowledges and consents
to the assignment by the Purchaser to the Trustee of all of the Purchaser's
rights against the Seller pursuant to this Agreement insofar as such rights
relate to Mortgage Loans transferred to the Trustee and to the enforcement or
exercise of any right or remedy against the Seller pursuant to this Agreement by
the

                                       20

<PAGE>

Trustee. Such enforcement of a right or remedy by the Trustee shall have the
same force and effect as if the right or remedy had been enforced or exercised
by the Purchaser directly.

          Section 7.09 SURVIVAL. The representations and warranties set forth in
Sections 3.01 and 3.02 and the provisions of Article V hereof shall survive the
purchase of the Mortgage Loans hereunder.

                                       21

<PAGE>

                   IN WITNESS WHEREOF, the Seller and the Purchaser have caused
their names to be signed to this Mortgage Loan Purchase Agreement by their
respective officers thereunto duly authorized as of the day and year fist above
written.

Purchaser. If the Seller does not cure such defect or deliver such missing
document within such time period, the Originator shall either repurchase or
substitute for such Mortgage Loan pursuant to Section 2.03 of the Pooling and
Servicing Agreement.

          The Purchaser hereby acknowledges its acceptance of all right, title
and interest to the Mortgage Loans and other property, now existing and
hereafter created, conveyed to it pursuant to Section 2.01.

          The parties hereto intend that the transaction set forth herein be a
sale by the Seller to the Purchaser of all the Seller's right, title and
interest in and to the Mortgage Loans and other property described above. In the
event the transaction set forth herein is deemed not to be a sale, the Seller
hereby grants to the Purchaser a security interest in all of the Seller's right,
title and interest in, to and under the Mortgage Loans and other property
described above, whether now existing or hereafter created, to secure all of the
Seller's obligations hereunder; and this Agreement shall constitute a security
agreement under applicable law.

          The Originator shall cause the Assignments which were delivered in
blank to be completed and shall cause all Assignments referred to in Section
2.02(iii) hereof and, to the extent necessary, in Section 2.02(iv) hereof to be
recorded; PROVIDED, HOWEVER, the Originator need not cause to be recorded any
Assignment which relates to a Mortgage Loan in any jurisdiction under the laws
of which, as evidenced by an Opinion of Counsel delivered by the Originator to
the NIMs Insurer, the Trustee and the Rating Agencies on or before the Closing
Date, the recordation of such assignment is not necessary to protect the
Trustee's interest in the related Mortgage Loan; PROVIDED, HOWEVER,
notwithstanding the delivery of any Opinion of Counsel, each Assignment shall be
submitted for

                                        4

<PAGE>

recording by the Originator in the manner described above, at no expense to the
Trust Fund or Trustee, upon the earliest to occur of: (i) reasonable direction
by Holders of Certificates entitled to at least 25% of the Voting Rights, (ii)
the occurrence of a Master Servicer Event of Termination, (iii) the occurrence
of a bankruptcy, insolvency or foreclosure relating to the Master Servicer, (iv)
the occurrence of a servicing transfer as described in Section 7.02 of the
Pooling and Servicing Agreement or (v) if the Originator is not the Master
Servicer and with respect to any one Assignment the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Mortgagor under the related Mortgage
and (vi) any Mortgage Loan that is 90 days or more Delinquent. The Originator
shall be required to deliver such assignments for recording within 45 days of
the Closing Date. The Originator shall furnish the Trustee, or its designated
agent, with a copy of each Assignment submitted for recording. In the event that
any such Assignment is lost or returned unrecorded because of a defect therein,
the Originator shall promptly have a substitute Assignment prepared or have such
defect cured, as the case may be, and thereafter cause each such Assignment to
be duly recorded. In the event that any Mortgage Note is endorsed in blank as of
the Closing Date, promptly following the Closing Date the Depositor shall cause
to be completed such endorsements "Pay to the order of Wells Fargo Bank
Minnesota, N.A., as Trustee, without recourse."

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

          Section 2.03      PAYMENT OF PURCHASE PRICE FOR THE MORTGAGE LOANS.

          In consideration of the sale of the Mortgage Loans from the Seller to
the Purchaser on the Closing Date, the Purchaser agrees to pay to the Seller on

                   (f) The related Mortgage Note and Mortgage are genuine and
each is the legal, valid and binding obligation of the maker thereof,
enforceable in accordance with its terms except as such enforcement may be
limited by bankruptcy, insolvency, reorganization or other similar laws
affecting the enforcement of creditors' rights generally and by general equity
principles (regardless of whether such enforcement is considered in a proceeding
in equity or at law);

                   (g) The related Mortgage is a valid and enforceable first or
second lien on the related Mortgaged Property, which Mortgaged Property is free
and clear of all encumbrances and liens (including mechanics liens) having
priority over the first or second lien of the Mortgage except for: (i) liens for
real estate taxes and assessments not yet due and payable; (ii) covenants,
conditions and restrictions, rights of way, easements and other matters of

<PAGE>

connection with the origination of the related Mortgage Loan, (iii) other
matters to which like properties are commonly subject which do not materially
interfere with the benefits of the security intended to be provided by such
Mortgage and (iv) the first lien on the Mortgaged Property, in the case of the
Mortgages that are second liens;

                   (h) Any security agreement, chattel mortgage or equivalent
document related to such Mortgage Loan establishes and creates a valid and
enforceable first or second lien on the Mortgaged Property;

                   (i) As of the last calendar day of September 2001 and with
respect to any Mortgage Loan that had a payment due on or before September 1,
2001, the related Monthly Payment due on September 1, 2001 has been received. In
addition, none of the Initial Mortgage Loans have been 30 or more days
delinquent in the last 12 months and none of the Initial Mortgage Loans have
been 30 or more days delinquent for two payment periods in the last 12 months;

                   (j) Neither the Originator nor the Seller has 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 under the Mortgage Loan;

                   (k) Neither the Originator nor the Seller has impaired,
waived, altered or modified the related Mortgage or Mortgage Note in any
material respect, or satisfied, canceled, rescinded or subordinated such
Mortgage or Mortgage Note in whole or in part or released all or any material
portion of the Mortgaged Property from the lien of the Mortgage, or executed any
instrument of release, cancellation, rescission or satisfaction of the Mortgage
Note or Mortgage;

                   (l) As of the Cut-off Date, the Mortgage has not been
satisfied, canceled or subordinated, in whole or in part, or rescinded, and the
Mortgaged Property has not been released from the lien of the Mortgage, in whole
or in part (except for a release that does not materially impair the security of
the Mortgage Loan or a release the effect of which is reflected in the
Loan-to-Value Ratio for the Mortgage Loan as set forth in the Schedule of
Mortgage Loans), nor has any instrument been executed that would effect any such
release, cancellation, subordination or rescission;

                   (m) No Mortgage Loan is subject to any right of recission,
set-off, counterclaim or defense, including the defense of usury, nor will the
operation of any of the terms of any Mortgage Note or Mortgage, or the exercise
of any right thereunder, render either the Mortgage Note or Mortgage
unenforceable in whole or in part, or subject to any right of recission,
set-off, counterclaim or defense, including the defense of usury, and no such
right of recission, set-off, counterclaim or defense has been asserted with
respect thereto;

                   (n) To the Originator's knowledge, there is no proceeding
pending for the total or partial condemnation and no eminent domain proceedings
pending affecting any Mortgaged Property;

                   (o) Each Mortgage Loan is covered by either (i) a mortgage
title insurance policy or other generally acceptable form of insurance policy
customary in the jurisdiction where the Mortgaged Property is located or (ii) if
generally acceptable in the jurisdiction where the Mortgaged

                                        7

<PAGE>

Property is located, an attorney's opinion of title given by an attorney
licensed to practice law in the jurisdiction where the Mortgaged Property is
located. All of the Originator's rights under such policies, opinions or other
instruments shall be transferred and assigned to Purchaser upon sale and
assignment of the Mortgage Loans hereunder. The title insurance policy has been
issued by a title insurer licensed to do business in the jurisdiction where the
Mortgaged Property is located, insuring the original lender, its successor and
assigns, as to the first or second priority lien of the Mortgage in the original
principal amount of the Mortgage Loan, subject to the exceptions contained in
such policy. The Originator is the sole insured of such mortgagee title
insurance policy, and such mortgagee title insurance policy is in full force and
effect and will be in force and effect upon the consummation of the transactions
contemplated by this Agreement. Neither the Originator nor any affiliate of the
Originator has made, and the Originator has no knowledge of, any claims under
such mortgagee title insurance policy. The Originator is not aware of any action
by a prior holder and neither the Originator nor any affiliate of the Originator
has done, by act or omission, anything which could impair the coverage or
enforceability of such mortgagee title insurance policy or the accuracy of such
attorney's opinion of title;

                   (p) There is no material default, breach, violation or event
of acceleration existing under the related Mortgage or the related Mortgage Note
and no event which, with the passage of time or with notice and the expiration
of any grace or cure period, would constitute a material default, breach,
violation or event of acceleration, other than a payment delinquency that is for
a payment due after the date specified in (i) above. Neither the Originator, the
Seller nor any affiliate of the Originator or the Seller has waived any default,
breach, violation or event of acceleration;

                   (q) With respect to any Mortgage Loan which provides for an
adjustable interest rate, all rate adjustments have been performed in accordance
with the terms of the related Mortgage Note or subsequent modifications, if any;

                   (r) To the Originator's knowledge, there are no delinquent
taxes, ground rents, water charges, sewer rents, assessments, insurance
premiums, leasehold payments, including assessments payable in future
installments or other outstanding charges, affecting the related Mortgaged
Property;

                   (s) No foreclosure proceedings are pending against the
Mortgaged Property and the Mortgage Loan is not subject to any pending
bankruptcy or insolvency proceeding, and to the Originator's best knowledge, no
material litigation or lawsuit relating to the Mortgage Loan is pending;

                   (t) The Mortgage Loan obligates the mortgagor thereunder to
maintain a hazard insurance policy ("Hazard Insurance") in an amount at least
equal to the lesser of (i) the maximum insurable value of such improvements or
(ii) the principal balance of the Mortgage Loan with a standard mortgagee
clause, in either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance,

and, if applicable, flood insurance policy at the Mortgagor's cost and expense,
and on the Mortgagor's failure to do so, authorizes the holder of the Mortgage
to obtain and maintain such insurance at the Mortgagor's cost and expense, and
to seek reimbursement therefor from the Mortgagor. The Mortgaged Property is
covered by Hazard Insurance;

                   (u) The Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

                   (v) The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage Loan
in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
customary and enforceable provisions such as to render the rights and remedies
of the holder thereof adequate for the realization against the Mortgaged
Property of the benefits of the security provided thereby, including (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale or judicial
foreclosure and (ii) otherwise by judicial foreclosure. Since the date of
origination of the Mortgage Loan, the Mortgaged Property has not been subject to
any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not
filed for protection under applicable bankruptcy laws. There is no homestead or
other exemption available to the Mortgagor that would interfere with the right
to sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage. In the event the Mortgage constitutes a deed of trust, a trustee, duly
qualified under applicable law to serve as such, as been properly designated and
currently so serves and is named in the Mortgage, and no fees or expenses are or
will become payable by Purchaser to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Originator or any affiliate of the Originator and
the Originator has no knowledge of any relief requested or allowed to the
Mortgagor under the Soldiers and Sailors Civil Relief Act of 1940;

                   (w) Except as set forth in the appraisal which forms part of
the related Mortgage File, the Mortgaged Property, normal wear and tear
excepted, is undamaged by waste, fire, earthquake or earth movement, windstorm,
flood, tornado or other casualty so as to affect materially and adversely the
value of the Mortgaged Property as security for the Mortgage Loan or the use for
which the premises were intended;

                   (x) To the Originator's knowledge, there was no fraud
involved in the origination of the Mortgage Loan by the mortgagee or by the
Mortgagor, any appraiser or any other party involved in the origination of the
Mortgage Loan;

                   (y) Each Mortgage File contains an appraisal of the Mortgaged
Property indicating an appraised value equal to the appraised value identified
for such Mortgaged Property on the Mortgage Loan Schedule. Each appraisal has
been performed in accordance with the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989;

                   (z) To the best of the Originator's knowledge, all parties
which have had any interest in the Mortgage Loan, whether as mortgagee,
assignee, pledgee or otherwise, are (or, during the period in which they held
and disposed of such interest, were) in compliance with any and all

                                        9

<PAGE>

applicable "doing business" and licensing requirements of the laws of the state
wherein the Mortgaged Property is located;

                   (aa) No improvements on the related Mortgaged Property (upon
which value was given) encroach on adjoining properties (and in the case of a
condominium unit, such improvements are within the project with respect to that
unit), and no improvements on adjoining properties encroach upon the Mortgaged
Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

                   (bb) Each Mortgage Loan was originated or acquired by a
savings and loan association, a savings bank, a commercial bank or similar
banking institution which is supervised and examined by a federal or state
authority, or by a mortgagee approved by the Secretary of HUD. Each Mortgage
Loan was originated substantially in accordance with the Originator's
underwriting criteria, which are at least as stringent as the underwriting
criteria set forth in the Prospectus Supplement. Each Mortgage Loan is currently
being serviced by the Originator and has been serviced by the Originator since
the date of origination of such Mortgage Loan;

                   (cc) (i) Principal payments on the Mortgage Loan commenced no
more than two months after the proceeds of the Mortgage Loan were disbursed and
(ii) each Mortgage Note is payable on the first day of each month;

                   (dd) Other than with respect to not more than 8.98% of the
Initial Mortgage Loans (by aggregate principal balance of the Initial Mortgage
Loans as of the Cut-off Date), which are "balloon payment" mortgage loans, each
Initial Mortgage Loan is fully amortizing;

                   (ee) The Mortgage Loan bears interest at the Mortgage Rate
and the Mortgage Note does not permit negative amortization. No Mortgage Loan
bearing interest at an adjustable rate permits the Mortgagor to convert the
Mortgage Loan to a fixed rate Mortgage Loan;

                   (ff) With respect to escrow deposits, if any, all such
payments are in the possession of, or under the control of, the Master Servicer
and there exist no deficiencies in connection therewith for which customary
arrangements for repayment thereof have not been made. No escrow deposits or
escrow advances or other charges or payments due the Master Servicer have been
capitalized under any Mortgage or the related Mortgage Note;

                   (gg) No Mortgage Loan contains provisions pursuant to which
scheduled payments are: (i) paid or partially paid with funds deposited in any
separate account established by the Originator, the Seller, the Mortgagor, or
anyone on behalf of the Mortgagor; or (ii) paid by any source other than the
Mortgagor or contains any other similar provisions which may constitute a
"buydown" provision. The Mortgage Loan is not a graduated payment mortgage loan
and the Mortgage Loan does not have a shared appreciation or other contingent
interest feature;

                   (hh) As of the origination date of each Mortgage Loan, the
related Mortgaged Property is lawfully permitted to be occupied under applicable
law;

                                       10

<PAGE>

                   (ii) No law relating to servicing, collection or notification
practices and no law relating to origination practices, has been violated in
connection with any Mortgage Loan transferred to the Purchaser pursuant to this
Agreement, including, without limitation, usury, truth in lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws. The Mortgage Loan has been serviced in accordance with the
terms of the Mortgage Note.

                   (jj) No Mortgage Loan was made in connection with (a) the
construction or rehabilitation of a Mortgaged Property or (b) facilitating the
trade-in or exchange of a Mortgaged Property;

                   (kk) The proceeds of the Mortgage Loan have been fully
disbursed to or for the account of the Mortgagor and there is no obligation for
the Mortgagee to advance additional funds thereunder, and any and all
requirements as to completion of any on-site or off-site improvement and as to
disbursements of any escrow funds therefor have been complied with. All costs,
fees and expenses incurred in making or closing the Mortgage Loan and the
recording of the Mortgage have been paid, and the Mortgagor is not entitled to
any refund of any amounts paid or due to the, Mortgagee pursuant to the Mortgage
Note or Mortgage;

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

                   (mm) As to each Mortgage Loan, interest is calculated on the
Mortgage Note on the basis of twelve 30-day months and a 360 day year;

                   (nn) The Mortgaged Property consists of one of the following:
detached or semi-detached one- to four-family dwelling units, townhouses,
individual condominium units and individual units in planned unit developments,
or manufactured homes;

                   (oo) Each Mortgage Loan constitutes a "qualified mortgage"
within the meaning of Section 860G(a)(3) of the Code;

                   (pp) The Mortgage Loans were not intentionally selected by
the Seller in a manner intended to adversely affect the Purchaser or the Trust;

                   (qq) The representations, warranties and covenants, set forth
in this Section shall survive the Closing Date;

                   (rr) The Mortgage Loans have original terms to maturity
ranging from 15 to 30 years;

                   (ss) With respect to the Mortgage Loans, no more than 37.47%;
13.42%; 11.64% and 11.45% of the Initial Mortgage Loans, by Cut-off Date
Principal Balance will be secured by Mortgaged Properties located in California,
New Jersey, Virginia and Florida, respectively; and 69.50% of the Initial
Mortgage Loans, by Cut-off Date Principal Balance will be secured by real

                                       11

<PAGE>

property with a single family residence erected thereon and 12.44% of the
Initial Mortgage Loans, by the Cut-off Date Principal Balance are secured by
condominiums;

                   (tt) As of the Cut-off Date, each Mortgage Loan, had a
Loan-to-Value-Ratio that was less than or equal to 90.00%;

                   (uu) With respect to each Mortgage Loan, the Mortgage Note
related thereto bears a fixed Mortgage Rate or an adjustable Mortgage Rate which
will be adjusted on each Adjustment Date to equal the Index plus the Gross
Margin, rounded to the nearest or next highest 0.125%, subject to the Periodic
Rate Cap, the Maximum Mortgage Rate and the Minimum Mortgage Rate;

                   (vv) The average Cut-off Date Principal Balance of the
Initial Mortgage Loans is $356,760.44;

                   (ww) No Mortgage Loan is subject to the requirements of the
Home Ownership and Equity Protection Act of 1994 ("HOEPA") and no Mortgage Loan
is in violation of any state law or ordinance similar to HOEPA;

                   (xx) Each Mortgage Loan conforms, and all Mortgage Loans in
the aggregate conform, in all material respects, to the description thereof set
forth in the Prospectus Supplement;

                   (yy) With respect to second lien Mortgage Loans, either (a)
no consent for the Mortgage Loan is required by the holder of the related first
lien or (b) such consent has been obtained and is contained in the Mortgage
File; and

                   (zz) Each Mortgage Note is comprised of one original
promissory note and each such promissory note constitutes an "instrument" for
purposes of section 9-102(a)(65) of the UCC.

          Section 3.02 ORIGINATOR REPRESENTATIONS AND WARRANTIES RELATING TO THE
ORIGINATOR. The Originator represents, warrants and covenants to the Purchaser

                   (iv) The Originator is not in violation of, and the execution

                   (v) The Originator is a HUD approved mortgagee pursuant to

          Section 3.04 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It
is understood and agreed that the representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and

                                       15

<PAGE>

warranties contained herein that are made to the knowledge or the best knowledge
of the Originator or as to which the Originator has no knowledge, if it is
discovered that the substance of any such representation and warranty is
inaccurate and the inaccuracy materially and adversely affects the value of the
related Mortgage Loan, or the interest therein of the Purchaser or the
Purchaser's assignee, designee or transferee, then notwithstanding the
Originator's lack of knowledge with respect to the substance of such
representation and warranty being inaccurate at the time the representation and
warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation and warranty and the Originator shall take such action described
in the following paragraphs of this Section 3.04 in respect of such Mortgage
Loan. Upon discovery by either the Originator, the Master Servicer or the
Purchaser of a breach of any of the foregoing representations and warranties
that materially and adversely affects the value of the Mortgage Loans or the
interest of the Purchaser (or which materially and adversely affects the
interests of the Purchaser in the related Mortgage Loan in the case of a
representation and warranty relating to a particular Mortgage Loan), the party
discovering such breach shall give prompt written notice to the others.

          Within 90 days of the earlier of either discovery by or notice to the
Originator of any breach of a representation or warranty made by the Originator
that materially and adversely affects the value of a Mortgage Loan or the
Mortgage Loans or the interest therein of the Purchaser, the Originator shall
use its best efforts promptly to cure such breach in all material respects and,
if such breach cannot be cured, the Originator shall, at the Purchaser's option,
repurchase such Mortgage Loan at the Purchase Price. In the event that a breach
shall involve any representation or warranty set forth in Section 3.02 or 3.03
and such breach cannot be cured within 90 days of the earlier of either
discovery by or notice to the Originator of such breach, all of the Mortgage
Loans shall, at the Purchaser's option, be repurchased by the Originator at the
Purchase Price. The Originator may, at the request of the Purchaser and assuming
the Originator has a Qualified Substitute Mortgage Loan, rather than repurchase
a deficient Mortgage Loan as provided above, remove such Mortgage Loan and
substitute in its place a Qualified Substitute Mortgage Loan or Loans. If the
Originator does not provide a Qualified Substitute Mortgage Loan or Loans, it
shall repurchase the deficient Mortgage Loan. Any repurchase of a Mortgage
Loan(s) pursuant to the foregoing provisions of this Section 3.04 shall occur on
a date designated by the Purchaser and shall be accomplished by deposit in
accordance with Section 2.03 of the Pooling and Servicing Agreement. Any
repurchase or substitution required by this Section shall be made in a manner
consistent with Section 2.03 of the Pooling and Servicing Agreement.

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

          As to any Deleted Mortgage Loan for which the Originator substitutes a
Qualified Substitute Mortgage Loan or Loans, the Originator shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling

                                       16

<PAGE>

and Servicing Agreement, with the Mortgage Note endorsed as required therein.
The Originator shall deposit in the Collection Account the Monthly Payment less
the Servicing Fee due on such Qualified Substitute Mortgage Loan or Loans in the
month following the date of such substitution. Monthly Payments due with respect
to Qualified Substitute Mortgage Loans in the month of substitution will be
retained by the Originator. For the month of substitution, distributions to the
Purchaser will include the Monthly Payment due on such Deleted Mortgage Loan in
the month of substitution, and the Originator shall thereafter be entitled to
retain all amounts subsequently received by the Originator in respect of such
Deleted Mortgage Loan. Upon such substitution, the Qualified Substitute Mortgage
Loans shall be subject to the terms of this Agreement in all respects, and the
Originator shall be deemed to have made with respect to such Qualified
Substitute Mortgage Loan or Loans as of the date of substitution, the covenants,
representations and warranties set forth in Sections 3.01, 3.02 and 3.03.

          It is understood and agreed that the representations and warranties
set forth in Section 3.01 shall survive delivery of the respective Mortgage
Files to the Trustee on behalf of the Purchaser.

          It is understood and agreed that the obligations of the Originator set
forth in Section 3.04 to cure, repurchase and substitute for a defective
Mortgage Loan and to indemnify the Purchaser as provided in Section 5.01
constitute the sole remedies of the Purchaser respecting a missing or defective
document or a breach of the representations and warranties contained in Section
3.01, 3.02 or 3.03.

                                   ARTICLE IV.

                             ORIGINATOR'S COVENANTS

          Section 4.01 COVENANTS OF THE ORIGINATOR. The Originator hereby
covenants that except for the transfer hereunder, neither the Originator nor the
Seller will sell, pledge, assign or transfer to any other Person, or grant,
create, incur, assume or suffer to exist any Lien on any Mortgage Loan, or any
interest therein; the Originator will notify the Trustee, as assignee of the
Purchaser, of the existence of any Lien on any Mortgage Loan immediately upon
discovery thereof, and the Originator will defend the right, title and interest
of the Trust, as assignee of the Purchaser, in, to and under the Mortgage Loans,
against all claims of third parties claiming through or under the Originator or
the Seller; provided, however, that nothing in this Section 4.01 shall prevent
or be deemed to prohibit the Originator or the Seller from suffering to exist
upon any of the Mortgage Loans any Liens for municipal or other local taxes and
other governmental charges if such taxes or governmental charges shall not at
the time be due and payable or if the Originator or the Seller shall currently

<PAGE>

          Section 5.01      INDEMNIFICATION.

                   (a) The Originator agrees to indemnify and hold harmless the
Purchaser, each of its directors, each of its officers and each person or entity
who controls the Purchaser or any such person, within the meaning of Section 15
of the Securities Act, against any and all losses, claims, damages or
liabilities, joint and several, as incurred, to which the Purchaser, or any such
person or entity may become subject, under the Securities Act or otherwise, and
will reimburse the Purchaser, each such director and officer and each such
controlling person for any legal or other expenses incurred by the Purchaser or
such controlling person in connection with investigating or defending any such
losses, claims, damages or liabilities, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Originator or the omission or
the alleged omission to state therein a material fact necessary in order to make
the statements in the Prospectus Supplement or any amendment or supplement to
the Prospectus Supplement approved in writing by the Originator, in the light of
the circumstances under which they were made, not misleading, but only to the
extent that such untrue statement or alleged untrue statement or omission or
alleged omission relates to the Originator Information contained in the
Prospectus Supplement, (ii) any untrue statement or alleged untrue statement of
any material fact contained in the information on any computer tape furnished to
the Purchaser or an affiliate thereof by or on behalf of the Originator
containing information regarding the assets of the Trust or (iii) any untrue
statement or alleged untrue statement of any material fact contained in any
information provided by the Originator to the Purchaser or any affiliate
thereof, or any material omission from the information purported to be provided
hereby, and disseminated to PricewaterhouseCoopers LLP or prospective investors
(directly or indirectly through available information systems) in connection
with the issuance, marketing or offering of the Certificates. This indemnity
agreement will be in addition to any liability which the Originator may
otherwise have.

                   (b) The Purchaser agrees to indemnify and hold harmless the
Seller and the Originator, each of their respective officers, directors and each
person or entity who controls the Seller, the Originator or any such person,
against any and all losses, claims, damages or liabilities, joint and several,
to which the Seller, the Originator or any such person or entity may become
subject, under the Securities Act or otherwise, and will reimburse the Seller
and/or the Originator for any legal or other expenses incurred by the Seller,
the Originator, each such officer and director and such controlling person in
connection with investigating or defending any such losses, claims, damages or
liabilities insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Prospectus
Supplement or any amendment or supplement to the Prospectus Supplement or the
omission or the alleged omission to state therein a material fact necessary in
order to make the statements in the Prospectus Supplement or any amendment or
supplement to the Prospectus Supplement, in the light of the circumstances under
which they were made, not misleading, but only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission is not
contained in the Originator Information in the Prospectus Supplement. This
indemnity agreement will be in addition to any liability which the Purchaser may
otherwise have.

                                       18

                   (c) Promptly after receipt by any indemnified party under
this Article V of notice of any claim or the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article V.

          If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Article V for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation.

          Any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article V consist of the Purchaser, by the Originator, if the
indemnified parties in this Article V consist of the Originator, or by the
Seller, if the indemnified parties under this Article V consist of the Seller.

          Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to consent

                                       19

<PAGE>

to a settlement of any action, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and the indemnifying party has not
previously provided the indemnified party with written notice of its objection
to such settlement. No indemnifying party shall effect any settlement of any
pending or threatened proceeding in respect of which an indemnified party is or
could have been a party and indemnity is or could have been sought hereunder,
without the written consent of such indemnified party, unless settlement
includes an unconditional release of such indemnified party from all liability
and claims that are the subject matter of such proceeding.

                   (d) In order to provide for just and equitable contribution
in circumstances in which the indemnity agreement provided for in this Article
is for any reason held to be unenforceable although applicable in accordance
with its terms, the Seller and the Originator, on the one hand, and the
Purchaser, on the other, shall contribute to the aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by said indemnity
agreement incurred by the Seller, the Originator and the Purchaser in such
proportions as shall be appropriate to reflect the relative benefits received by
the Seller and the Originator on the one hand and the Purchaser on the other
from the sale of the Mortgage Loans such that the Purchaser is responsible for
the lesser of (i) 0.25% thereof and (ii) 0.25% of the aggregate proceeds to the
Seller from the sale of the Mortgage Loans and the Originator shall be
responsible for the balance; PROVIDED, HOWEVER, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section, each
officer and director of the Purchaser and each person, if any, who controls the
Purchaser within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Purchaser, each director of the Originator,
each officer of the Originator, and each person, if any, who controls the
Originator within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Originator and each director of the Seller,
each officer of the Seller, and each person, if any, who controls the Seller
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Seller.

                   (e) The Originator agrees to indemnify and to hold each of
the Purchaser, the Trustee, each of the officers and directors of each such
entity and each person or entity who controls each such entity or person and
each Certificateholder harmless against any and all claims, losses, penalties,
fines, forfeitures, legal fees and related costs, judgments, and any other
costs, fees and expenses that the Purchaser, the Trustee, or any such person or
entity and any Certificateholder may sustain in any way (i) related to the
failure of the Originator to perform its duties in compliance with the terms of
this Agreement, (ii) arising from a breach by the Originator of its
representations and warranties in Section 3.01, 3.02 or 3.03 of this Agreement
or (iii) related to the origination or prior servicing of the Mortgage Loans by
reason of any acts, omissions, or alleged acts or omissions of the Originator,
the Seller or any servicer. The Originator shall immediately notify the
Purchaser, the Trustee and each Certificateholder if a claim is made by a third
party with respect to this Agreement. The Originator shall assume the defense of
any such claim and pay all expenses in connection therewith, including
reasonable counsel fees, and promptly pay, discharge and satisfy any judgment or
decree which may be entered against the Purchaser, the Trustee or any such
person or entity and/or any Certificateholder in respect of such claim.

<PAGE>

          if to the Seller:

                   Option One Owner Trust 2001-1A
                   c/o Wilmington Trust Company
                   One Rodney Square North
                   1100 North Market Street
                   Wilmington, Delaware 19890
                   Attention: Corporate Trust Administration

or such other address as may hereafter be furnished to the Originator and the
Purchaser in writing by the Seller.

          Section 7.04 SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions of terms of this Agreement shall be held
invalid for any reason whatsoever, 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 of
enforceability of the other provisions of this Agreement.

          Section 7.05 COUNTERPARTS. This Agreement may be executed in one or
more counterparts and by the different parties hereto on separate counterparts,
each of which, when so executed, shall be deemed to be an original and such
counterparts, together, shall constitute one and the same agreement.

          Section 7.06 FURTHER AGREEMENTS. The Purchaser, the Seller and the
Originator each agree to execute and deliver to the other such additional
documents, instruments or agreements as may be necessary or reasonable and
appropriate to effectuate the purposes of this Agreement or in connection with
the issuance of any series of Certificates representing interests in the
Mortgage Loans.

          Without limiting the generality of the foregoing, as a further
inducement for the Purchaser to purchase the Mortgage Loans from the Seller, the
Originator will cooperate with the Purchaser in connection with the sale of any
of the securities representing interests in the Mortgage Loans. In that
connection, the Originator will provide to the Purchaser any and all information
and appropriate verification of information, whether through letters of its
auditors and counsel or otherwise, as the Purchaser shall reasonably request and
will provide to the Purchaser such additional representations and warranties,
covenants, opinions of counsel, letters from auditors, and certificates of
public officials or officers of the Originator as are reasonably required in
connection with such transactions and the offering of investment grade
securities rated by the Rating Agencies.

          Section 7.07 INTENTION OF THE PARTIES. It is the intention of the
parties that the Purchaser is purchasing, and the Seller is selling, the
Mortgage Loans rather than pledging the Mortgage Loans to secure a loan by the
Purchaser to the Seller. Accordingly, the parties hereto each intend to treat
the transaction for federal income tax purposes and all other purposes as a sale
by the Seller, and a purchase by the Purchaser, of the Mortgage Loans. The
Purchaser will have the right to review the Mortgage Loans and the related
Mortgage Files to determine the characteristics of the Mortgage Loans which will
affect the federal income tax consequences of owning the Mortgage Loans and the

                                       22

<PAGE>

Seller will cooperate with all reasonable requests made by the Purchaser in the
course of such review.

          Section 7.08 SUCCESSORS AND ASSIGNS, ASSIGNMENT OF PURCHASE AGREEMENT.
This Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Originator, the Purchaser, the Trustee and the NIMs Insurer. The
NIMs Insurer shall be a third party beneficiary hereof and may enforce the terms
hereof as if a party hereto. The obligations of the Seller and the Originator
under this Agreement cannot be assigned or delegated to a third party without
the consent of the Purchaser which consent shall be at the Purchaser's sole
discretion, except that the Purchaser acknowledges and agrees that the Seller or
the Originator may assign its obligations hereunder to any Person into which the
Seller or the Originator is merged or any corporation resulting from any merger,
conversion or consolidation to which the Seller or the Originator is a party or
any Person succeeding to the business of the Seller or the Originator. The
parties hereto acknowledge that the Purchaser is acquiring the Mortgage Loans
for the purpose of contributing them to a trust that will issue a series of
Certificates representing undivided interests in such Mortgage Loans. As an
inducement to the Purchaser to purchase the Mortgage Loans, the Seller and the
Originator each acknowledge and consent to the assignment by the Purchaser to
the Trustee of all of the Purchaser's rights against the Seller and the
Originator pursuant to this Agreement insofar as such rights relate to Mortgage
Loans transferred to the Trustee and to the enforcement or exercise of any right
or remedy against the Seller or the Originator pursuant to this Agreement by the
Trustee. Such enforcement of a right or remedy by the Trustee shall have the
same force and effect as if the right or remedy had been enforced or exercised
by the Purchaser directly.

          Section 7.09 SURVIVAL. The representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 and the provisions of Article V hereof shall
survive the purchase of the Mortgage Loans hereunder.

          Section 7.10 OWNER TRUSTEE. It is expressly understood and agreed by
the parties to this Agreement that (a) this Agreement is executed and delivered
by Wilmington Trust Company, not individually or personally but solely as Owner
Trustee of the Seller, in the exercise of the powers and authority conferred and
vested in it as trustee, (b) each of the representations, undertakings and
agreements herein made on the part of the Seller is made and intended not as
personal representations, undertakings and agreements by Wilmington Trust
Company but is made and intended for the purpose of binding only the Seller, (c)
nothing herein contained shall be construed as creating any liability on
Wilmington Trust Company, individually or personally, to perform any covenant
either expressed or implied contained herein, all such liability, if any, being
expressly waived by the parties to this Agreement and by any person claiming by,
through or under the parties to this Agreement and (d) under no circumstances
shall Wilmington Trust Company be personally liable for the payment of any
indebtedness or expenses of the Seller or be liable for the breach or failure of
any obligation, representation, warranty or covenant made or undertaken by the
Seller under this Agreement or any other document.

and interest to the Mortgage Loans and other property, now existing and
hereafter created, conveyed to it pursuant to Section 2.01.

          The parties hereto intend that the transaction set forth herein be a
sale by the Seller to the Purchaser of all the Seller's right, title and
interest in and to the Mortgage Loans and other property described above. In the
event the transaction set forth herein is deemed not to be a sale, the Seller
hereby grants to the Purchaser a security interest in all of the Seller's right,
title and interest in, to and under the Mortgage Loans and other property
described above, whether now existing or hereafter created, to secure all of the
Seller's obligations hereunder; and this Agreement shall constitute a security
agreement under applicable law.

          The Originator shall cause the Assignments which were delivered in
blank to be completed and shall cause all Assignments referred to in Section
2.02(iii) hereof and, to the extent necessary, in Section 2.02(iv) hereof to be
recorded; PROVIDED, HOWEVER, the Originator need not cause to be recorded any
Assignment which relates to a Mortgage Loan in any jurisdiction under the laws
of which, as evidenced by an Opinion of Counsel delivered by the Originator to
the NIMs Insurer, the Trustee and the Rating Agencies on or before the Closing
Date, the recordation of such assignment is not necessary to protect the
Trustee's interest in the related Mortgage Loan; PROVIDED, HOWEVER,
notwithstanding the delivery of any Opinion of Counsel, each Assignment shall be
submitted for

                                        4

by Holders of Certificates entitled to at least 25% of the Voting Rights, (ii)
the occurrence of a Master Servicer Event of Termination, (iii) the occurrence
of a bankruptcy, insolvency or foreclosure relating to the Master Servicer, (iv)
the occurrence of a servicing transfer as described in Section 7.02 of the

Servicer and with respect to any one Assignment the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Mortgagor under the related Mortgage
and (vi) any Mortgage Loan that is 90 days or more Delinquent. The Originator
shall be required to deliver such assignments for recording within 45 days of
the Closing Date. The Originator shall furnish the Trustee, or its designated
agent, with a copy of each Assignment submitted for recording. In the event that
any such Assignment is lost or returned unrecorded because of a defect therein,
the Originator shall promptly have a substitute Assignment prepared or have such
defect cured, as the case may be, and thereafter cause each such Assignment to
be duly recorded. In the event that any Mortgage Note is endorsed in blank as of
the Closing Date, promptly following the Closing Date the Depositor shall cause
to be completed such endorsements "Pay to the order of Wells Fargo Bank
Minnesota, N.A., as Trustee, without recourse."

          The Originator shall forward to the Purchaser original documents
evidencing an assumption, modification, consolidation or extension of any
Mortgage Loan entered into in accordance with the Pooling and Servicing
Agreement within two weeks of their execution; PROVIDED, HOWEVER, that the
Originator shall provide the Purchaser with a certified true copy of any such
document submitted for recordation within two weeks of its execution, and shall
provide the original of any document submitted for recordation or a copy of such
document certified by the appropriate public recording office to be a true and
complete copy of the original within 270 days of its submission for recordation.
In the event that the Originator cannot provide a copy of such document
certified by the public recording office within such 270 day period, the
Originator shall deliver to the Purchaser, within such 270 day period, an
Officer's Certificate of the Master Servicer which shall (A) identify the
recorded document, (B) state that the recorded document has not been delivered
to the Purchaser due solely to a delay caused by the public recording office,

office to record and return a document submitted for recordation, if known, and

delivered to the Purchaser, and, upon receipt of a copy of such document
certified by the public recording office, the Originator shall immediately
deliver such document to the Purchaser. In the event the appropriate public
recording office will not certify as to the accuracy of such document, the
Originator shall deliver a copy of such document certified by an officer of the
Originator to be a true and complete copy of the original to the Purchaser.

each is the legal, valid and binding obligation of the maker thereof,
enforceable in accordance with its terms except as such enforcement may be
limited by bankruptcy, insolvency, reorganization or other similar laws
affecting the enforcement of creditors' rights generally and by general equity
principles (regardless of whether such enforcement is considered in a proceeding
in equity or at law);

                   (g) The related Mortgage is a valid and enforceable first or
second lien on the related Mortgaged Property, which Mortgaged Property is free
and clear of all encumbrances and liens (including mechanics liens) having
priority over the first or second lien of the Mortgage except for: (i) liens for
real estate taxes and assessments not yet due and payable; (ii) covenants,
conditions and restrictions, rights of way, easements and other matters of

<PAGE>

connection with the origination of the related Mortgage Loan, (iii) other
matters to which like properties are commonly subject which do not materially
interfere with the benefits of the security intended to be provided by such
Mortgage and (iv) the first lien on the Mortgaged Property, in the case of the
Mortgages that are second liens;

                   (h) Any security agreement, chattel mortgage or equivalent
document related to such Mortgage Loan establishes and creates a valid and
enforceable first or second lien on the Mortgaged Property;

                   (i) As of the last calendar day of September 2001 and with
respect to any Mortgage Loan that had a payment due on or before September 1,
2001, the related Monthly Payment due on September 1, 2001 has been received. In
addition, none of the Initial Mortgage Loans have been 30 or more days
delinquent in the last 12 months and none of the Initial Mortgage Loans have
been 30 or more days delinquent for two payment periods in the last 12 months;

                   (j) Neither the Originator nor the Seller has 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 under the Mortgage Loan;

                   (k) Neither the Originator nor the Seller has impaired,
waived, altered or modified the related Mortgage or Mortgage Note in any
material respect, or satisfied, canceled, rescinded or subordinated such

the Mortgage Loan or a release the effect of which is reflected in the
Loan-to-Value Ratio for the Mortgage Loan as set forth in the Schedule of
Mortgage Loans), nor has any instrument been executed that would effect any such
release, cancellation, subordination or rescission;

                   (m) No Mortgage Loan is subject to any right of recission,
set-off, counterclaim or defense, including the defense of usury, nor will the
operation of any of the terms of any Mortgage Note or Mortgage, or the exercise
of any right thereunder, render either the Mortgage Note or Mortgage
unenforceable in whole or in part, or subject to any right of recission,
set-off, counterclaim or defense, including the defense of usury, and no such
right of recission, set-off, counterclaim or defense has been asserted with
respect thereto;

                   (n) To the Originator's knowledge, there is no proceeding
pending for the total or partial condemnation and no eminent domain proceedings
pending affecting any Mortgaged Property;

                   (o) Each Mortgage Loan is covered by either (i) a mortgage
title insurance policy or other generally acceptable form of insurance policy
customary in the jurisdiction where the Mortgaged Property is located or (ii) if
generally acceptable in the jurisdiction where the Mortgaged

                                        7

<PAGE>

Property is located, an attorney's opinion of title given by an attorney
licensed to practice law in the jurisdiction where the Mortgaged Property is
located. All of the Originator's rights under such policies, opinions or other
instruments shall be transferred and assigned to Purchaser upon sale and
assignment of the Mortgage Loans hereunder. The title insurance policy has been
issued by a title insurer licensed to do business in the jurisdiction where the
Mortgaged Property is located, insuring the original lender, its successor and
assigns, as to the first or second priority lien of the Mortgage in the original
principal amount of the Mortgage Loan, subject to the exceptions contained in
such policy. The Originator is the sole insured of such mortgagee title
insurance policy, and such mortgagee title insurance policy is in full force and
effect and will be in force and effect upon the consummation of the transactions
contemplated by this Agreement. Neither the Originator nor any affiliate of the
Originator has made, and the Originator has no knowledge of, any claims under
such mortgagee title insurance policy. The Originator is not aware of any action
by a prior holder and neither the Originator nor any affiliate of the Originator
has done, by act or omission, anything which could impair the coverage or
enforceability of such mortgagee title insurance policy or the accuracy of such
attorney's opinion of title;

                   (p) There is no material default, breach, violation or event
of acceleration existing under the related Mortgage or the related Mortgage Note
and no event which, with the passage of time or with notice and the expiration
of any grace or cure period, would constitute a material default, breach,
violation or event of acceleration, other than a payment delinquency that is for
a payment due after the date specified in (i) above. Neither the Originator, the
Seller nor any affiliate of the Originator or the Seller has waived any default,
breach, violation or event of acceleration;

                   (q) With respect to any Mortgage Loan which provides for an
adjustable interest rate, all rate adjustments have been performed in accordance
with the terms of the related Mortgage Note or subsequent modifications, if any;

                   (r) To the Originator's knowledge, there are no delinquent
taxes, ground rents, water charges, sewer rents, assessments, insurance
premiums, leasehold payments, including assessments payable in future
installments or other outstanding charges, affecting the related Mortgaged
Property;

                   (s) No foreclosure proceedings are pending against the
Mortgaged Property and the Mortgage Loan is not subject to any pending
bankruptcy or insolvency proceeding, and to the Originator's best knowledge, no
material litigation or lawsuit relating to the Mortgage Loan is pending;

                   (t) The Mortgage Loan obligates the mortgagor thereunder to
maintain a hazard insurance policy ("Hazard Insurance") in an amount at least
equal to the lesser of (i) the maximum insurable value of such improvements or
(ii) the principal balance of the Mortgage Loan with a standard mortgagee
clause, in either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance,

                                        8

<PAGE>

and, if applicable, flood insurance policy at the Mortgagor's cost and expense,
and on the Mortgagor's failure to do so, authorizes the holder of the Mortgage
to obtain and maintain such insurance at the Mortgagor's cost and expense, and
to seek reimbursement therefor from the Mortgagor. The Mortgaged Property is
covered by Hazard Insurance;

                   (u) The Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

                   (v) The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage Loan
in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
customary and enforceable provisions such as to render the rights and remedies
of the holder thereof adequate for the realization against the Mortgaged
Property of the benefits of the security provided thereby, including (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale or judicial
foreclosure and (ii) otherwise by judicial foreclosure. Since the date of
origination of the Mortgage Loan, the Mortgaged Property has not been subject to
any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not
filed for protection under applicable bankruptcy laws. There is no homestead or
other exemption available to the Mortgagor that would interfere with the right
to sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage. In the event the Mortgage constitutes a deed of trust, a trustee, duly
qualified under applicable law to serve as such, as been properly designated and
currently so serves and is named in the Mortgage, and no fees or expenses are or
will become payable by Purchaser to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Originator or any affiliate of the Originator and
the Originator has no knowledge of any relief requested or allowed to the
Mortgagor under the Soldiers and Sailors Civil Relief Act of 1940;

                   (w) Except as set forth in the appraisal which forms part of
the related Mortgage File, the Mortgaged Property, normal wear and tear
excepted, is undamaged by waste, fire, earthquake or earth movement, windstorm,
flood, tornado or other casualty so as to affect materially and adversely the
value of the Mortgaged Property as security for the Mortgage Loan or the use for
which the premises were intended;

                   (x) To the Originator's knowledge, there was no fraud
involved in the origination of the Mortgage Loan by the mortgagee or by the
Mortgagor, any appraiser or any other party involved in the origination of the
Mortgage Loan;

                   (y) Each Mortgage File contains an appraisal of the Mortgaged
Property indicating an appraised value equal to the appraised value identified
for such Mortgaged Property on the Mortgage Loan Schedule. Each appraisal has
been performed in accordance with the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989;

                   (z) To the best of the Originator's knowledge, all parties
which have had any interest in the Mortgage Loan, whether as mortgagee,
assignee, pledgee or otherwise, are (or, during the period in which they held
and disposed of such interest, were) in compliance with any and all

                                        9

<PAGE>

applicable "doing business" and licensing requirements of the laws of the state
wherein the Mortgaged Property is located;

                   (aa) No improvements on the related Mortgaged Property (upon
which value was given) encroach on adjoining properties (and in the case of a
condominium unit, such improvements are within the project with respect to that
unit), and no improvements on adjoining properties encroach upon the Mortgaged
Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

                   (bb) Each Mortgage Loan was originated or acquired by a
savings and loan association, a savings bank, a commercial bank or similar
banking institution which is supervised and examined by a federal or state
authority, or by a mortgagee approved by the Secretary of HUD. Each Mortgage
Loan was originated substantially in accordance with the Originator's
underwriting criteria, which are at least as stringent as the underwriting
criteria set forth in the Prospectus Supplement. Each Mortgage Loan is currently
being serviced by the Originator and has been serviced by the Originator since
the date of origination of such Mortgage Loan;

                   (cc) (i) Principal payments on the Mortgage Loan commenced no
more than two months after the proceeds of the Mortgage Loan were disbursed and
(ii) each Mortgage Note is payable on the first day of each month;

                   (dd) Other than with respect to not more than 3.88% of the
Initial Mortgage Loans (by aggregate principal balance of the Initial Mortgage
Loans as of the Cut-off Date), which are "balloon payment" mortgage loans, each
Initial Mortgage Loan is fully amortizing;

                   (ee) The Mortgage Loan bears interest at the Mortgage Rate
and the Mortgage Note does not permit negative amortization. No Mortgage Loan
bearing interest at an adjustable rate permits the Mortgagor to convert the
Mortgage Loan to a fixed rate Mortgage Loan;

                   (ff) With respect to escrow deposits, if any, all such
payments are in the possession of, or under the control of, the Master Servicer
and there exist no deficiencies in connection therewith for which customary
arrangements for repayment thereof have not been made. No escrow deposits or
escrow advances or other charges or payments due the Master Servicer have been
capitalized under any Mortgage or the related Mortgage Note;

                   (gg) No Mortgage Loan contains provisions pursuant to which
scheduled payments are: (i) paid or partially paid with funds deposited in any
separate account established by the Originator, the Seller, the Mortgagor, or
anyone on behalf of the Mortgagor; or (ii) paid by any source other than the
Mortgagor or contains any other similar provisions which may constitute a
"buydown" provision. The Mortgage Loan is not a graduated payment mortgage loan
and the Mortgage Loan does not have a shared appreciation or other contingent
interest feature;

                   (hh) As of the origination date of each Mortgage Loan, the
related Mortgaged Property is lawfully permitted to be occupied under applicable
law;

                                       10

<PAGE>

                   (ii) No law relating to servicing, collection or notification
practices and no law relating to origination practices, has been violated in
connection with any Mortgage Loan transferred to the Purchaser pursuant to this
Agreement, including, without limitation, usury, truth in lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws. The Mortgage Loan has been serviced in accordance with the
terms of the Mortgage Note.

                   (jj) No Mortgage Loan was made in connection with (a) the
construction or rehabilitation of a Mortgaged Property or (b) facilitating the
trade-in or exchange of a Mortgaged Property;

                   (kk) The proceeds of the Mortgage Loan have been fully
disbursed to or for the account of the Mortgagor and there is no obligation for
the Mortgagee to advance additional funds thereunder, and any and all
requirements as to completion of any on-site or off-site improvement and as to
disbursements of any escrow funds therefor have been complied with. All costs,
fees and expenses incurred in making or closing the Mortgage Loan and the
recording of the Mortgage have been paid, and the Mortgagor is not entitled to
any refund of any amounts paid or due to the, Mortgagee pursuant to the Mortgage
Note or Mortgage;

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

                   (mm) As to each Mortgage Loan, interest is calculated on the
Mortgage Note on the basis of twelve 30-day months and a 360 day year;

                   (nn) The Mortgaged Property consists of one of the following:
detached or semi-detached one- to four-family dwelling units, townhouses,
individual condominium units and individual units in planned unit developments,
or manufactured homes;

                   (oo) Each Mortgage Loan constitutes a "qualified mortgage"
within the meaning of Section 860G(a)(3) of the Code;

                   (pp) The Mortgage Loans were not intentionally selected by
the Seller in a manner intended to adversely affect the Purchaser or the Trust;

                   (qq) The representations, warranties and covenants, set forth
in this Section shall survive the Closing Date;

                   (rr) The Mortgage Loans have original terms to maturity
ranging from 15 to 30 years;

                   (ss) With respect to the Mortgage Loans, no more than 36.04%;
8.60%; 6.35% and 6.35% of the Initial Mortgage Loans, by Cut-off Date Principal
Balance will be secured by Mortgaged Properties located in California, New York,
Massachusetts and Florida, respectively; and 78.41% of the Initial Mortgage
Loans, by Cut-off Date Principal Balance will be secured by real

                                       11

<PAGE>

property with a single family residence erected thereon and 3.18% of the Initial
Mortgage Loans, by the Cut-off Date Principal Balance are secured by
condominiums;

                   (tt) As of the Cut-off Date, each Mortgage Loan, had a
Loan-to-Value-Ratio that was less than or equal to 95.00%;

                   (uu) With respect to each Mortgage Loan, the Mortgage Note
related thereto bears a fixed Mortgage Rate or an adjustable Mortgage Rate which
will be adjusted on each Adjustment Date to equal the Index plus the Gross
Margin, rounded to the nearest or next highest 0.125%, subject to the Periodic
Rate Cap, the Maximum Mortgage Rate and the Minimum Mortgage Rate;

                   (vv) The average Cut-off Date Principal Balance of the
Initial Mortgage Loans is $350,902.95;

                   (ww) No Mortgage Loan is subject to the requirements of the
Home Ownership and Equity Protection Act of 1994 ("HOEPA") and no Mortgage Loan
is in violation of any state law or ordinance similar to HOEPA;

                   (xx) Each Mortgage Loan conforms, and all Mortgage Loans in
the aggregate conform, in all material respects, to the description thereof set
forth in the Prospectus Supplement;

                   (yy) With respect to second lien Mortgage Loans, either (a)
no consent for the Mortgage Loan is required by the holder of the related first
lien or (b) such consent has been obtained and is contained in the Mortgage
File; and

                   (zz) Each Mortgage Note is comprised of one original
promissory note and each such promissory note constitutes an "instrument" for
purposes of section 9-102(a)(65) of the UCC.

          Section 3.02 ORIGINATOR REPRESENTATIONS AND WARRANTIES RELATING TO THE
ORIGINATOR. The Originator represents, warrants and covenants to the Purchaser

                   (iv) The Originator is not in violation of, and the execution
and delivery of this Agreement by the Originator and its performance and

materially and adversely affect the condition (financial or otherwise) or the
operation of the Originator or its assets or might have consequences that would

hereunder;

                   (v) The Originator is a HUD approved mortgagee pursuant to

<PAGE>

                   (xi) Except with respect to any statement regarding the

          Section 3.04 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It
is understood and agreed that the representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and

                                       15

<PAGE>

warranties contained herein that are made to the knowledge or the best knowledge
of the Originator or as to which the Originator has no knowledge, if it is
discovered that the substance of any such representation and warranty is
inaccurate and the inaccuracy materially and adversely affects the value of the
related Mortgage Loan, or the interest therein of the Purchaser or the
Purchaser's assignee, designee or transferee, then notwithstanding the
Originator's lack of knowledge with respect to the substance of such
representation and warranty being inaccurate at the time the representation and
warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation and warranty and the Originator shall take such action described
in the following paragraphs of this Section 3.04 in respect of such Mortgage
Loan. Upon discovery by either the Originator, the Master Servicer or the
Purchaser of a breach of any of the foregoing representations and warranties
that materially and adversely affects the value of the Mortgage Loans or the
interest of the Purchaser (or which materially and adversely affects the
interests of the Purchaser in the related Mortgage Loan in the case of a
representation and warranty relating to a particular Mortgage Loan), the party
discovering such breach shall give prompt written notice to the others.

          Within 90 days of the earlier of either discovery by or notice to the
Originator of any breach of a representation or warranty made by the Originator
that materially and adversely affects the value of a Mortgage Loan or the
Mortgage Loans or the interest therein of the Purchaser, the Originator shall
use its best efforts promptly to cure such breach in all material respects and,
if such breach cannot be cured, the Originator shall, at the Purchaser's option,
repurchase such Mortgage Loan at the Purchase Price. In the event that a breach
shall involve any representation or warranty set forth in Section 3.02 or 3.03
and such breach cannot be cured within 90 days of the earlier of either
discovery by or notice to the Originator of such breach, all of the Mortgage
Loans shall, at the Purchaser's option, be repurchased by the Originator at the
Purchase Price. The Originator may, at the request of the Purchaser and assuming
the Originator has a Qualified Substitute Mortgage Loan, rather than repurchase
a deficient Mortgage Loan as provided above, remove such Mortgage Loan and
substitute in its place a Qualified Substitute Mortgage Loan or Loans. If the
Originator does not provide a Qualified Substitute Mortgage Loan or Loans, it
shall repurchase the deficient Mortgage Loan. Any repurchase of a Mortgage
Loan(s) pursuant to the foregoing provisions of this Section 3.04 shall occur on
a date designated by the Purchaser and shall be accomplished by deposit in
accordance with Section 2.03 of the Pooling and Servicing Agreement. Any
repurchase or substitution required by this Section shall be made in a manner
consistent with Section 2.03 of the Pooling and Servicing Agreement.

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

          As to any Deleted Mortgage Loan for which the Originator substitutes a
Qualified Substitute Mortgage Loan or Loans, the Originator shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling

                                       16

<PAGE>

and Servicing Agreement, with the Mortgage Note endorsed as required therein.
The Originator shall deposit in the Collection Account the Monthly Payment less
the Servicing Fee due on such Qualified Substitute Mortgage Loan or Loans in the
month following the date of such substitution. Monthly Payments due with respect
to Qualified Substitute Mortgage Loans in the month of substitution will be
retained by the Originator. For the month of substitution, distributions to the
Purchaser will include the Monthly Payment due on such Deleted Mortgage Loan in
the month of substitution, and the Originator shall thereafter be entitled to
retain all amounts subsequently received by the Originator in respect of such
Deleted Mortgage Loan. Upon such substitution, the Qualified Substitute Mortgage
Loans shall be subject to the terms of this Agreement in all respects, and the
Originator shall be deemed to have made with respect to such Qualified
Substitute Mortgage Loan or Loans as of the date of substitution, the covenants,
representations and warranties set forth in Sections 3.01, 3.02 and 3.03.

          It is understood and agreed that the representations and warranties
set forth in Section 3.01 shall survive delivery of the respective Mortgage
Files to the Trustee on behalf of the Purchaser.

          It is understood and agreed that the obligations of the Originator set
forth in Section 3.04 to cure, repurchase and substitute for a defective
Mortgage Loan and to indemnify the Purchaser as provided in Section 5.01
constitute the sole remedies of the Purchaser respecting a missing or defective
document or a breach of the representations and warranties contained in Section
3.01, 3.02 or 3.03.

                                   ARTICLE IV.

                             ORIGINATOR'S COVENANTS

          Section 4.01 COVENANTS OF THE ORIGINATOR. The Originator hereby
covenants that except for the transfer hereunder, neither the Originator nor the
Seller will sell, pledge, assign or transfer to any other Person, or grant,
create, incur, assume or suffer to exist any Lien on any Mortgage Loan, or any
interest therein; the Originator will notify the Trustee, as assignee of the
Purchaser, of the existence of any Lien on any Mortgage Loan immediately upon
discovery thereof, and the Originator will defend the right, title and interest
of the Trust, as assignee of the Purchaser, in, to and under the Mortgage Loans,
against all claims of third parties claiming through or under the Originator or
the Seller; provided, however, that nothing in this Section 4.01 shall prevent
or be deemed to prohibit the Originator or the Seller from suffering to exist
upon any of the Mortgage Loans any Liens for municipal or other local taxes and
other governmental charges if such taxes or governmental charges shall not at
the time be due and payable or if the Originator or the Seller shall currently
be contesting the validity thereof in good faith by appropriate proceedings and
shall have set aside on its books adequate reserves with respect thereto.

<PAGE>

          Section 5.01      INDEMNIFICATION.

                   (a) The Originator agrees to indemnify and hold harmless the
Purchaser, each of its directors, each of its officers and each person or entity
who controls the Purchaser or any such person, within the meaning of Section 15
of the Securities Act, against any and all losses, claims, damages or
liabilities, joint and several, as incurred, to which the Purchaser, or any such
person or entity may become subject, under the Securities Act or otherwise, and
will reimburse the Purchaser, each such director and officer and each such
controlling person for any legal or other expenses incurred by the Purchaser or
such controlling person in connection with investigating or defending any such
losses, claims, damages or liabilities, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Originator or the omission or
the alleged omission to state therein a material fact necessary in order to make
the statements in the Prospectus Supplement or any amendment or supplement to
the Prospectus Supplement approved in writing by the Originator, in the light of
the circumstances under which they were made, not misleading, but only to the
extent that such untrue statement or alleged untrue statement or omission or
alleged omission relates to the Originator Information contained in the
Prospectus Supplement, (ii) any untrue statement or alleged untrue statement of
any material fact contained in the information on any computer tape furnished to
the Purchaser or an affiliate thereof by or on behalf of the Originator
containing information regarding the assets of the Trust or (iii) any untrue
statement or alleged untrue statement of any material fact contained in any
information provided by the Originator to the Purchaser or any affiliate
thereof, or any material omission from the information purported to be provided
hereby, and disseminated to PricewaterhouseCoopers LLP or prospective investors
(directly or indirectly through available information systems) in connection
with the issuance, marketing or offering of the Certificates. This indemnity
agreement will be in addition to any liability which the Originator may
otherwise have.

                   (b) The Purchaser agrees to indemnify and hold harmless the
Seller and the Originator, each of their respective officers, directors and each
person or entity who controls the Seller, the Originator or any such person,
against any and all losses, claims, damages or liabilities, joint and several,
to which the Seller, the Originator or any such person or entity may become
subject, under the Securities Act or otherwise, and will reimburse the Seller
and/or the Originator for any legal or other expenses incurred by the Seller,
the Originator, each such officer and director and such controlling person in
connection with investigating or defending any such losses, claims, damages or
liabilities insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Prospectus
Supplement or any amendment or supplement to the Prospectus Supplement or the
omission or the alleged omission to state therein a material fact necessary in
order to make the statements in the Prospectus Supplement or any amendment or
supplement to the Prospectus Supplement, in the light of the circumstances under
which they were made, not misleading, but only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission is not
contained in the Originator Information in the Prospectus Supplement. This
indemnity agreement will be in addition to any liability which the Purchaser may
otherwise have.

                                       18

<PAGE>

                   (c) Promptly after receipt by any indemnified party under
this Article V of notice of any claim or the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article V.

          If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Article V for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation.

          Any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article V consist of the Purchaser, by the Originator, if the
indemnified parties in this Article V consist of the Originator, or by the
Seller, if the indemnified parties under this Article V consist of the Seller.

          Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to consent

                                       19

<PAGE>

to a settlement of any action, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and the indemnifying party has not
previously provided the indemnified party with written notice of its objection
to such settlement. No indemnifying party shall effect any settlement of any
pending or threatened proceeding in respect of which an indemnified party is or
could have been a party and indemnity is or could have been sought hereunder,
without the written consent of such indemnified party, unless settlement
includes an unconditional release of such indemnified party from all liability
and claims that are the subject matter of such proceeding.

                   (d) In order to provide for just and equitable contribution
in circumstances in which the indemnity agreement provided for in this Article
is for any reason held to be unenforceable although applicable in accordance
with its terms, the Seller and the Originator, on the one hand, and the
Purchaser, on the other, shall contribute to the aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by said indemnity
agreement incurred by the Seller, the Originator and the Purchaser in such
proportions as shall be appropriate to reflect the relative benefits received by
the Seller and the Originator on the one hand and the Purchaser on the other
from the sale of the Mortgage Loans such that the Purchaser is responsible for
the lesser of (i) 0.25% thereof and (ii) 0.25% of the aggregate proceeds to the
Seller from the sale of the Mortgage Loans and the Originator shall be
responsible for the balance; PROVIDED, HOWEVER, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section, each
officer and director of the Purchaser and each person, if any, who controls the
Purchaser within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Purchaser, each director of the Originator,
each officer of the Originator, and each person, if any, who controls the
Originator within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Originator and each director of the Seller,
each officer of the Seller, and each person, if any, who controls the Seller
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Seller.

                   (e) The Originator agrees to indemnify and to hold each of
the Purchaser, the Trustee, each of the officers and directors of each such
entity and each person or entity who controls each such entity or person and
each Certificateholder harmless against any and all claims, losses, penalties,
fines, forfeitures, legal fees and related costs, judgments, and any other
costs, fees and expenses that the Purchaser, the Trustee, or any such person or
entity and any Certificateholder may sustain in any way (i) related to the
failure of the Originator to perform its duties in compliance with the terms of
this Agreement, (ii) arising from a breach by the Originator of its
representations and warranties in Section 3.01, 3.02 or 3.03 of this Agreement
or (iii) related to the origination or prior servicing of the Mortgage Loans by
reason of any acts, omissions, or alleged acts or omissions of the Originator,
the Seller or any servicer. The Originator shall immediately notify the
Purchaser, the Trustee and each Certificateholder if a claim is made by a third
party with respect to this Agreement. The Originator shall assume the defense of
any such claim and pay all expenses in connection therewith, including
reasonable counsel fees, and promptly pay, discharge and satisfy any judgment or
decree which may be entered against the Purchaser, the Trustee or any such
person or entity and/or any Certificateholder in respect of such claim.

          Section 6.01 TERMINATION. The respective obligations and
responsibilities of the Originator, the Seller and the Purchaser created hereby
shall terminate, except for the Originator's indemnity obligations as provided
herein upon the termination of the Trust as provided in Article X of the Pooling

<PAGE>

          if to the Seller:

                   Option One Owner Trust 2001-1B
                   c/o Wilmington Trust Company
                   One Rodney Square North
                   1100 North Market Street
                   Wilmington, Delaware 19890
                   Attention: Corporate Trust Administration

or such other address as may hereafter be furnished to the Originator and the
Purchaser in writing by the Seller.

          Section 7.04 SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions of terms of this Agreement shall be held
invalid for any reason whatsoever, 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 of
enforceability of the other provisions of this Agreement.

          Section 7.05 COUNTERPARTS. This Agreement may be executed in one or
more counterparts and by the different parties hereto on separate counterparts,
each of which, when so executed, shall be deemed to be an original and such
counterparts, together, shall constitute one and the same agreement.

          Section 7.06 FURTHER AGREEMENTS. The Purchaser, the Seller and the
Originator each agree to execute and deliver to the other such additional
documents, instruments or agreements as may be necessary or reasonable and
appropriate to effectuate the purposes of this Agreement or in connection with
the issuance of any series of Certificates representing interests in the
Mortgage Loans.

          Without limiting the generality of the foregoing, as a further
inducement for the Purchaser to purchase the Mortgage Loans from the Seller, the
Originator will cooperate with the Purchaser in connection with the sale of any
of the securities representing interests in the Mortgage Loans. In that
connection, the Originator will provide to the Purchaser any and all information
and appropriate verification of information, whether through letters of its
auditors and counsel or otherwise, as the Purchaser shall reasonably request and
will provide to the Purchaser such additional representations and warranties,
covenants, opinions of counsel, letters from auditors, and certificates of
public officials or officers of the Originator as are reasonably required in
connection with such transactions and the offering of investment grade
securities rated by the Rating Agencies.

          Section 7.07 INTENTION OF THE PARTIES. It is the intention of the
parties that the Purchaser is purchasing, and the Seller is selling, the
Mortgage Loans rather than pledging the Mortgage Loans to secure a loan by the
Purchaser to the Seller. Accordingly, the parties hereto each intend to treat
the transaction for federal income tax purposes and all other purposes as a sale
by the Seller, and a purchase by the Purchaser, of the Mortgage Loans. The
Purchaser will have the right to review the Mortgage Loans and the related
Mortgage Files to determine the characteristics of the Mortgage Loans which will
affect the federal income tax consequences of owning the Mortgage Loans and the

                                       22

<PAGE>

Seller will cooperate with all reasonable requests made by the Purchaser in the
course of such review.

          Section 7.08 SUCCESSORS AND ASSIGNS, ASSIGNMENT OF PURCHASE AGREEMENT.
This Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Originator, the Purchaser, the Trustee and the NIMs Insurer. The
NIMs Insurer shall be a third party beneficiary hereof and may enforce the terms
hereof as if a party hereto. The obligations of the Seller and the Originator
under this Agreement cannot be assigned or delegated to a third party without
the consent of the Purchaser which consent shall be at the Purchaser's sole
discretion, except that the Purchaser acknowledges and agrees that the Seller or
the Originator may assign its obligations hereunder to any Person into which the
Seller or the Originator is merged or any corporation resulting from any merger,
conversion or consolidation to which the Seller or the Originator is a party or
any Person succeeding to the business of the Seller or the Originator. The
parties hereto acknowledge that the Purchaser is acquiring the Mortgage Loans
for the purpose of contributing them to a trust that will issue a series of
Certificates representing undivided interests in such Mortgage Loans. As an
inducement to the Purchaser to purchase the Mortgage Loans, the Seller and the
Originator each acknowledge and consent to the assignment by the Purchaser to
the Trustee of all of the Purchaser's rights against the Seller and the
Originator pursuant to this Agreement insofar as such rights relate to Mortgage
Loans transferred to the Trustee and to the enforcement or exercise of any right
or remedy against the Seller or the Originator pursuant to this Agreement by the
Trustee. Such enforcement of a right or remedy by the Trustee shall have the
same force and effect as if the right or remedy had been enforced or exercised
by the Purchaser directly.

          Section 7.09 SURVIVAL. The representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 and the provisions of Article V hereof shall
survive the purchase of the Mortgage Loans hereunder.

          Section 7.10 OWNER TRUSTEE. It is expressly understood and agreed by
the parties to this Agreement that (a) this Agreement is executed and delivered
by Wilmington Trust Company, not individually or personally but solely as Owner
Trustee of the Seller, in the exercise of the powers and authority conferred and
vested in it as trustee, (b) each of the representations, undertakings and
agreements herein made on the part of the Seller is made and intended not as
personal representations, undertakings and agreements by Wilmington Trust
Company but is made and intended for the purpose of binding only the Seller, (c)
nothing herein contained shall be construed as creating any liability on
Wilmington Trust Company, individually or personally, to perform any covenant
either expressed or implied contained herein, all such liability, if any, being
expressly waived by the parties to this Agreement and by any person claiming by,
through or under the parties to this Agreement and (d) under no circumstances
shall Wilmington Trust Company be personally liable for the payment of any
indebtedness or expenses of the Seller or be liable for the breach or failure of
any obligation, representation, warranty or covenant made or undertaken by the
Seller under this Agreement or any other document.

          The Purchaser hereby acknowledges its acceptance of all right, title
and interest to the Mortgage Loans and other property, now existing and
hereafter created, conveyed to it pursuant to Section 2.01.

          The parties hereto intend that the transaction set forth herein be a
sale by the Seller to the Purchaser of all the Seller's right, title and
interest in and to the Mortgage Loans and other property described above. In the
event the transaction set forth herein is deemed not to be a sale, the Seller
hereby grants to the Purchaser a security interest in all of the Seller's right,
title and interest in, to and under the Mortgage Loans and other property
described above, whether now existing or hereafter created, to secure all of the
Seller's obligations hereunder; and this Agreement shall constitute a security
agreement under applicable law.

          The Originator shall cause the Assignments which were delivered in
blank to be completed and shall cause all Assignments referred to in Section
2.02(iii) hereof and, to the extent necessary, in Section 2.02(iv) hereof to be
recorded; PROVIDED, HOWEVER, the Originator need not cause to be recorded any
Assignment which relates to a Mortgage Loan in any jurisdiction under the laws
of which, as evidenced by an Opinion of Counsel delivered by the Originator to
the NIMs Insurer, the Trustee and the Rating Agencies on or before the Closing
Date, the recordation of such assignment is not necessary to protect the
Trustee's interest in the related Mortgage Loan; PROVIDED, HOWEVER,
notwithstanding the delivery of any Opinion of Counsel, each Assignment shall be
submitted for

                                        4

by Holders of Certificates entitled to at least 25% of the Voting Rights, (ii)
the occurrence of a Master Servicer Event of Termination, (iii) the occurrence
of a bankruptcy, insolvency or foreclosure relating to the Master Servicer, (iv)
the occurrence of a servicing transfer as described in Section 7.02 of the
Pooling and Servicing Agreement or (v) if the Originator is not the Master
Servicer and with respect to any one Assignment the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Mortgagor under the related Mortgage
and (vi) any Mortgage Loan that is 90 days or more Delinquent. The Originator
shall be required to deliver such assignments for recording within 45 days of
the Closing Date. The Originator shall furnish the Trustee, or its designated
agent, with a copy of each Assignment submitted for recording. In the event that
any such Assignment is lost or returned unrecorded because of a defect therein,
the Originator shall promptly have a substitute Assignment prepared or have such
defect cured, as the case may be, and thereafter cause each such Assignment to
be duly recorded. In the event that any Mortgage Note is endorsed in blank as of
the Closing Date, promptly following the Closing Date the Depositor shall cause
to be completed such endorsements "Pay to the order of Wells Fargo Bank
Minnesota, N.A., as Trustee, without recourse."

          The Originator shall forward to the Purchaser original documents
evidencing an assumption, modification, consolidation or extension of any
Mortgage Loan entered into in accordance with the Pooling and Servicing
Agreement within two weeks of their execution; PROVIDED, HOWEVER, that the
Originator shall provide the Purchaser with a certified true copy of any such
document submitted for recordation within two weeks of its execution, and shall
provide the original of any document submitted for recordation or a copy of such
document certified by the appropriate public recording office to be a true and
complete copy of the original within 270 days of its submission for recordation.
In the event that the Originator cannot provide a copy of such document
certified by the public recording office within such 270 day period, the
Originator shall deliver to the Purchaser, within such 270 day period, an
Officer's Certificate of the Master Servicer which shall (A) identify the
recorded document, (B) state that the recorded document has not been delivered
to the Purchaser due solely to a delay caused by the public recording office,

office to record and return a document submitted for recordation, if known, and

delivered to the Purchaser, and, upon receipt of a copy of such document
certified by the public recording office, the Originator shall immediately
deliver such document to the Purchaser. In the event the appropriate public
recording office will not certify as to the accuracy of such document, the
Originator shall deliver a copy of such document certified by an officer of the
Originator to be a true and complete copy of the original to the Purchaser.

                   (f) The related Mortgage Note and Mortgage are genuine and
each is the legal, valid and binding obligation of the maker thereof,
enforceable in accordance with its terms except as such enforcement may be
limited by bankruptcy, insolvency, reorganization or other similar laws
affecting the enforcement of creditors' rights generally and by general equity
principles (regardless of whether such enforcement is considered in a proceeding
in equity or at law);

                   (g) The related Mortgage is a valid and enforceable first or
second lien on the related Mortgaged Property, which Mortgaged Property is free
and clear of all encumbrances and liens (including mechanics liens) having
priority over the first or second lien of the Mortgage except for: (i) liens for
real estate taxes and assessments not yet due and payable; (ii) covenants,
conditions and restrictions, rights of way, easements and other matters of
public record as of the date of recording of such Mortgage, such exceptions

<PAGE>

connection with the origination of the related Mortgage Loan, (iii) other
matters to which like properties are commonly subject which do not materially
interfere with the benefits of the security intended to be provided by such
Mortgage and (iv) the first lien on the Mortgaged Property, in the case of the
Mortgages that are second liens;

                   (h) Any security agreement, chattel mortgage or equivalent
document related to such Mortgage Loan establishes and creates a valid and
enforceable first or second lien on the Mortgaged Property;

                   (i) As of the last calendar day of September 2001 and with
respect to any Mortgage Loan that had a payment due on or before September 1,
2001, the related Monthly Payment due on September 1, 2001 has been received. In
addition, none of the Initial Mortgage Loans have been 30 or more days
delinquent in the last 12 months and none of the Initial Mortgage Loans have
been 30 or more days delinquent for two payment periods in the last 12 months;

                   (j) Neither the Originator nor the Seller has advanced funds,

other than the Mortgagor, directly or indirectly, for the payment of any amount
required under the Mortgage Loan;

                   (k) Neither the Originator nor the Seller has impaired,

or in part (except for a release that does not materially impair the security of
the Mortgage Loan or a release the effect of which is reflected in the
Loan-to-Value Ratio for the Mortgage Loan as set forth in the Schedule of
Mortgage Loans), nor has any instrument been executed that would effect any such
release, cancellation, subordination or rescission;

                   (m) No Mortgage Loan is subject to any right of recission,
set-off, counterclaim or defense, including the defense of usury, nor will the
operation of any of the terms of any Mortgage Note or Mortgage, or the exercise
of any right thereunder, render either the Mortgage Note or Mortgage
unenforceable in whole or in part, or subject to any right of recission,
set-off, counterclaim or defense, including the defense of usury, and no such
right of recission, set-off, counterclaim or defense has been asserted with
respect thereto;

                   (n) To the Originator's knowledge, there is no proceeding
pending for the total or partial condemnation and no eminent domain proceedings
pending affecting any Mortgaged Property;

                   (o) Each Mortgage Loan is covered by either (i) a mortgage
title insurance policy or other generally acceptable form of insurance policy
customary in the jurisdiction where the Mortgaged Property is located or (ii) if
generally acceptable in the jurisdiction where the Mortgaged

                                        7

<PAGE>

Property is located, an attorney's opinion of title given by an attorney
licensed to practice law in the jurisdiction where the Mortgaged Property is
located. All of the Originator's rights under such policies, opinions or other
instruments shall be transferred and assigned to Purchaser upon sale and
assignment of the Mortgage Loans hereunder. The title insurance policy has been
issued by a title insurer licensed to do business in the jurisdiction where the
Mortgaged Property is located, insuring the original lender, its successor and
assigns, as to the first or second priority lien of the Mortgage in the original
principal amount of the Mortgage Loan, subject to the exceptions contained in
such policy. The Originator is the sole insured of such mortgagee title
insurance policy, and such mortgagee title insurance policy is in full force and
effect and will be in force and effect upon the consummation of the transactions
contemplated by this Agreement. Neither the Originator nor any affiliate of the
Originator has made, and the Originator has no knowledge of, any claims under
such mortgagee title insurance policy. The Originator is not aware of any action
by a prior holder and neither the Originator nor any affiliate of the Originator
has done, by act or omission, anything which could impair the coverage or
enforceability of such mortgagee title insurance policy or the accuracy of such
attorney's opinion of title;

                   (p) There is no material default, breach, violation or event
of acceleration existing under the related Mortgage or the related Mortgage Note
and no event which, with the passage of time or with notice and the expiration
of any grace or cure period, would constitute a material default, breach,
violation or event of acceleration, other than a payment delinquency that is for
a payment due after the date specified in (i) above. Neither the Originator, the
Seller nor any affiliate of the Originator or the Seller has waived any default,
breach, violation or event of acceleration;

                   (q) With respect to any Mortgage Loan which provides for an
adjustable interest rate, all rate adjustments have been performed in accordance
with the terms of the related Mortgage Note or subsequent modifications, if any;

                   (r) To the Originator's knowledge, there are no delinquent
taxes, ground rents, water charges, sewer rents, assessments, insurance
premiums, leasehold payments, including assessments payable in future
installments or other outstanding charges, affecting the related Mortgaged
Property;

                   (s) No foreclosure proceedings are pending against the
Mortgaged Property and the Mortgage Loan is not subject to any pending
bankruptcy or insolvency proceeding, and to the Originator's best knowledge, no
material litigation or lawsuit relating to the Mortgage Loan is pending;

                   (t) The Mortgage Loan obligates the mortgagor thereunder to
maintain a hazard insurance policy ("Hazard Insurance") in an amount at least
equal to the lesser of (i) the maximum insurable value of such improvements or
(ii) the principal balance of the Mortgage Loan with a standard mortgagee
clause, in either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance,

                                        8

<PAGE>

and, if applicable, flood insurance policy at the Mortgagor's cost and expense,
and on the Mortgagor's failure to do so, authorizes the holder of the Mortgage
to obtain and maintain such insurance at the Mortgagor's cost and expense, and
to seek reimbursement therefor from the Mortgagor. The Mortgaged Property is
covered by Hazard Insurance;

                   (u) The Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

                   (v) The Mortgage contains an enforceable provision for the
acceleration of the payment of the unpaid principal balance of the Mortgage Loan
in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
customary and enforceable provisions such as to render the rights and remedies
of the holder thereof adequate for the realization against the Mortgaged
Property of the benefits of the security provided thereby, including (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale or judicial
foreclosure and (ii) otherwise by judicial foreclosure. Since the date of
origination of the Mortgage Loan, the Mortgaged Property has not been subject to
any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not
filed for protection under applicable bankruptcy laws. There is no homestead or
other exemption available to the Mortgagor that would interfere with the right
to sell the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage. In the event the Mortgage constitutes a deed of trust, a trustee, duly
qualified under applicable law to serve as such, as been properly designated and
currently so serves and is named in the Mortgage, and no fees or expenses are or
will become payable by Purchaser to the trustee under the deed of trust, except
in connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Originator or any affiliate of the Originator and
the Originator has no knowledge of any relief requested or allowed to the
Mortgagor under the Soldiers and Sailors Civil Relief Act of 1940;

                   (w) Except as set forth in the appraisal which forms part of
the related Mortgage File, the Mortgaged Property, normal wear and tear
excepted, is undamaged by waste, fire, earthquake or earth movement, windstorm,
flood, tornado or other casualty so as to affect materially and adversely the
value of the Mortgaged Property as security for the Mortgage Loan or the use for
which the premises were intended;

                   (x) To the Originator's knowledge, there was no fraud
involved in the origination of the Mortgage Loan by the mortgagee or by the
Mortgagor, any appraiser or any other party involved in the origination of the
Mortgage Loan;

                   (y) Each Mortgage File contains an appraisal of the Mortgaged
Property indicating an appraised value equal to the appraised value identified
for such Mortgaged Property on the Mortgage Loan Schedule. Each appraisal has
been performed in accordance with the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989;

                   (z) To the best of the Originator's knowledge, all parties
which have had any interest in the Mortgage Loan, whether as mortgagee,
assignee, pledgee or otherwise, are (or, during the period in which they held
and disposed of such interest, were) in compliance with any and all

                                        9

<PAGE>

applicable "doing business" and licensing requirements of the laws of the state
wherein the Mortgaged Property is located;

                   (aa) No improvements on the related Mortgaged Property (upon
which value was given) encroach on adjoining properties (and in the case of a
condominium unit, such improvements are within the project with respect to that
unit), and no improvements on adjoining properties encroach upon the Mortgaged
Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

                   (bb) Each Mortgage Loan was originated or acquired by a
savings and loan association, a savings bank, a commercial bank or similar
banking institution which is supervised and examined by a federal or state
authority, or by a mortgagee approved by the Secretary of HUD. Each Mortgage
Loan was originated substantially in accordance with the Originator's
underwriting criteria, which are at least as stringent as the underwriting
criteria set forth in the Prospectus Supplement. Each Mortgage Loan is currently
being serviced by the Originator and has been serviced by the Originator since
the date of origination of such Mortgage Loan;

                   (cc) (i) Principal payments on the Mortgage Loan commenced no
more than two months after the proceeds of the Mortgage Loan were disbursed and
(ii) each Mortgage Note is payable on the first day of each month;

                   (dd) Other than with respect to not more than 5.97% of the
Initial Mortgage Loans (by aggregate principal balance of the Initial Mortgage
Loans as of the Cut-off Date), which are "balloon payment" mortgage loans, each
Initial Mortgage Loan is fully amortizing;

                   (ee) The Mortgage Loan bears interest at the Mortgage Rate
and the Mortgage Note does not permit negative amortization. No Mortgage Loan
bearing interest at an adjustable rate permits the Mortgagor to convert the
Mortgage Loan to a fixed rate Mortgage Loan;

                   (ff) With respect to escrow deposits, if any, all such
payments are in the possession of, or under the control of, the Master Servicer
and there exist no deficiencies in connection therewith for which customary
arrangements for repayment thereof have not been made. No escrow deposits or
escrow advances or other charges or payments due the Master Servicer have been
capitalized under any Mortgage or the related Mortgage Note;

                   (gg) No Mortgage Loan contains provisions pursuant to which
scheduled payments are: (i) paid or partially paid with funds deposited in any
separate account established by the Originator, the Seller, the Mortgagor, or
anyone on behalf of the Mortgagor; or (ii) paid by any source other than the
Mortgagor or contains any other similar provisions which may constitute a
"buydown" provision. The Mortgage Loan is not a graduated payment mortgage loan
and the Mortgage Loan does not have a shared appreciation or other contingent
interest feature;

                   (hh) As of the origination date of each Mortgage Loan, the
related Mortgaged Property is lawfully permitted to be occupied under applicable
law;

                                       10

<PAGE>

                   (ii) No law relating to servicing, collection or notification
practices and no law relating to origination practices, has been violated in
connection with any Mortgage Loan transferred to the Purchaser pursuant to this
Agreement, including, without limitation, usury, truth in lending, real estate
settlement procedures, consumer credit protection, equal credit opportunity or
disclosure laws. The Mortgage Loan has been serviced in accordance with the
terms of the Mortgage Note.

                   (jj) No Mortgage Loan was made in connection with (a) the
construction or rehabilitation of a Mortgaged Property or (b) facilitating the
trade-in or exchange of a Mortgaged Property;

                   (kk) The proceeds of the Mortgage Loan have been fully
disbursed to or for the account of the Mortgagor and there is no obligation for
the Mortgagee to advance additional funds thereunder, and any and all
requirements as to completion of any on-site or off-site improvement and as to
disbursements of any escrow funds therefor have been complied with. All costs,
fees and expenses incurred in making or closing the Mortgage Loan and the
recording of the Mortgage have been paid, and the Mortgagor is not entitled to
any refund of any amounts paid or due to the, Mortgagee pursuant to the Mortgage
Note or Mortgage;

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

                   (mm) As to each Mortgage Loan, interest is calculated on the
Mortgage Note on the basis of twelve 30-day months and a 360 day year;

                   (nn) The Mortgaged Property consists of one of the following:
detached or semi-detached one- to four-family dwelling units, townhouses,
individual condominium units and individual units in planned unit developments,
or manufactured homes;

                   (oo) Each Mortgage Loan constitutes a "qualified mortgage"
within the meaning of Section 860G(a)(3) of the Code;

                   (pp) The Mortgage Loans were not intentionally selected by
the Seller in a manner intended to adversely affect the Purchaser or the Trust;

                   (qq) The representations, warranties and covenants, set forth
in this Section shall survive the Closing Date;

                   (rr) The Mortgage Loans have original terms to maturity
ranging from 15 to 30 years;

                   (ss) With respect to the Mortgage Loans, no more than 33.22%;
15.54%; 9.80% and 5.88% of the Initial Mortgage Loans, by Cut-off Date Principal
Balance will be secured by Mortgaged Properties located in California, New York,
Massachusetts and New Jersey, respectively; and 72.69% of the Initial Mortgage
Loans, by Cut-off Date Principal Balance will be secured by real

                                       11

<PAGE>

property with a single family residence erected thereon and 3.83% of the Initial
Mortgage Loans, by the Cut-off Date Principal Balance are secured by
condominiums;

                   (tt) As of the Cut-off Date, each Mortgage Loan, had a
Loan-to-Value-Ratio that was less than or equal to 100.00%;

                   (uu) With respect to each Mortgage Loan, the Mortgage Note
related thereto bears a fixed Mortgage Rate or an adjustable Mortgage Rate which
will be adjusted on each Adjustment Date to equal the Index plus the Gross
Margin, rounded to the nearest or next highest 0.125%, subject to the Periodic
Rate Cap, the Maximum Mortgage Rate and the Minimum Mortgage Rate;

                   (vv) The average Cut-off Date Principal Balance of the
Initial Mortgage Loans is $337,792.21;

                   (ww) No Mortgage Loan is subject to the requirements of the
Home Ownership and Equity Protection Act of 1994 ("HOEPA") and no Mortgage Loan
is in violation of any state law or ordinance similar to HOEPA;

                   (xx) Each Mortgage Loan conforms, and all Mortgage Loans in
the aggregate conform, in all material respects, to the description thereof set
forth in the Prospectus Supplement;

                   (yy) With respect to second lien Mortgage Loans, either (a)
no consent for the Mortgage Loan is required by the holder of the related first
lien or (b) such consent has been obtained and is contained in the Mortgage
File; and

                   (zz) Each Mortgage Note is comprised of one original
promissory note and each such promissory note constitutes an "instrument" for
purposes of section 9-102(a)(65) of the UCC.

          Section 3.02 ORIGINATOR REPRESENTATIONS AND WARRANTIES RELATING TO THE
ORIGINATOR. The Originator represents, warrants and covenants to the Purchaser

                   (iv) The Originator is not in violation of, and the execution

hereunder;

                   (v) The Originator is a HUD approved mortgagee pursuant to

                                       13

<PAGE>

                   (xi) Except with respect to any statement regarding the
intentions of the Purchaser, or any other statement contained herein the truth

          Section 3.04 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It
is understood and agreed that the representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and

                                       15

<PAGE>

warranties contained herein that are made to the knowledge or the best knowledge
of the Originator or as to which the Originator has no knowledge, if it is
discovered that the substance of any such representation and warranty is
inaccurate and the inaccuracy materially and adversely affects the value of the
related Mortgage Loan, or the interest therein of the Purchaser or the
Purchaser's assignee, designee or transferee, then notwithstanding the
Originator's lack of knowledge with respect to the substance of such
representation and warranty being inaccurate at the time the representation and
warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation and warranty and the Originator shall take such action described
in the following paragraphs of this Section 3.04 in respect of such Mortgage
Loan. Upon discovery by either the Originator, the Master Servicer or the
Purchaser of a breach of any of the foregoing representations and warranties
that materially and adversely affects the value of the Mortgage Loans or the
interest of the Purchaser (or which materially and adversely affects the
interests of the Purchaser in the related Mortgage Loan in the case of a
representation and warranty relating to a particular Mortgage Loan), the party
discovering such breach shall give prompt written notice to the others.

          Within 90 days of the earlier of either discovery by or notice to the
Originator of any breach of a representation or warranty made by the Originator
that materially and adversely affects the value of a Mortgage Loan or the
Mortgage Loans or the interest therein of the Purchaser, the Originator shall
use its best efforts promptly to cure such breach in all material respects and,
if such breach cannot be cured, the Originator shall, at the Purchaser's option,
repurchase such Mortgage Loan at the Purchase Price. In the event that a breach
shall involve any representation or warranty set forth in Section 3.02 or 3.03
and such breach cannot be cured within 90 days of the earlier of either
discovery by or notice to the Originator of such breach, all of the Mortgage
Loans shall, at the Purchaser's option, be repurchased by the Originator at the
Purchase Price. The Originator may, at the request of the Purchaser and assuming
the Originator has a Qualified Substitute Mortgage Loan, rather than repurchase
a deficient Mortgage Loan as provided above, remove such Mortgage Loan and
substitute in its place a Qualified Substitute Mortgage Loan or Loans. If the
Originator does not provide a Qualified Substitute Mortgage Loan or Loans, it
shall repurchase the deficient Mortgage Loan. Any repurchase of a Mortgage
Loan(s) pursuant to the foregoing provisions of this Section 3.04 shall occur on
a date designated by the Purchaser and shall be accomplished by deposit in
accordance with Section 2.03 of the Pooling and Servicing Agreement. Any
repurchase or substitution required by this Section shall be made in a manner
consistent with Section 2.03 of the Pooling and Servicing Agreement.

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

          As to any Deleted Mortgage Loan for which the Originator substitutes a
Qualified Substitute Mortgage Loan or Loans, the Originator shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling

                                       16

<PAGE>

and Servicing Agreement, with the Mortgage Note endorsed as required therein.
The Originator shall deposit in the Collection Account the Monthly Payment less
the Servicing Fee due on such Qualified Substitute Mortgage Loan or Loans in the
month following the date of such substitution. Monthly Payments due with respect
to Qualified Substitute Mortgage Loans in the month of substitution will be
retained by the Originator. For the month of substitution, distributions to the
Purchaser will include the Monthly Payment due on such Deleted Mortgage Loan in
the month of substitution, and the Originator shall thereafter be entitled to
retain all amounts subsequently received by the Originator in respect of such
Deleted Mortgage Loan. Upon such substitution, the Qualified Substitute Mortgage
Loans shall be subject to the terms of this Agreement in all respects, and the
Originator shall be deemed to have made with respect to such Qualified
Substitute Mortgage Loan or Loans as of the date of substitution, the covenants,
representations and warranties set forth in Sections 3.01, 3.02 and 3.03.

          It is understood and agreed that the representations and warranties
set forth in Section 3.01 shall survive delivery of the respective Mortgage
Files to the Trustee on behalf of the Purchaser.

          It is understood and agreed that the obligations of the Originator set
forth in Section 3.04 to cure, repurchase and substitute for a defective
Mortgage Loan and to indemnify the Purchaser as provided in Section 5.01
constitute the sole remedies of the Purchaser respecting a missing or defective
document or a breach of the representations and warranties contained in Section
3.01, 3.02 or 3.03.

                                   ARTICLE IV.

                             ORIGINATOR'S COVENANTS

          Section 4.01 COVENANTS OF THE ORIGINATOR. The Originator hereby
covenants that except for the transfer hereunder, neither the Originator nor the
Seller will sell, pledge, assign or transfer to any other Person, or grant,
create, incur, assume or suffer to exist any Lien on any Mortgage Loan, or any
interest therein; the Originator will notify the Trustee, as assignee of the
Purchaser, of the existence of any Lien on any Mortgage Loan immediately upon
discovery thereof, and the Originator will defend the right, title and interest
of the Trust, as assignee of the Purchaser, in, to and under the Mortgage Loans,
against all claims of third parties claiming through or under the Originator or
the Seller; provided, however, that nothing in this Section 4.01 shall prevent
or be deemed to prohibit the Originator or the Seller from suffering to exist
upon any of the Mortgage Loans any Liens for municipal or other local taxes and
other governmental charges if such taxes or governmental charges shall not at
the time be due and payable or if the Originator or the Seller shall currently
be contesting the validity thereof in good faith by appropriate proceedings and
shall have set aside on its books adequate reserves with respect thereto.

                                   ARTICLE V.

               INDEMNIFICATION WITH RESPECT TO THE MORTGAGE LOANS

                                       17

<PAGE>

          Section 5.01      INDEMNIFICATION.

                   (a) The Originator agrees to indemnify and hold harmless the
Purchaser, each of its directors, each of its officers and each person or entity
who controls the Purchaser or any such person, within the meaning of Section 15
of the Securities Act, against any and all losses, claims, damages or
liabilities, joint and several, as incurred, to which the Purchaser, or any such
person or entity may become subject, under the Securities Act or otherwise, and
will reimburse the Purchaser, each such director and officer and each such
controlling person for any legal or other expenses incurred by the Purchaser or
such controlling person in connection with investigating or defending any such
losses, claims, damages or liabilities, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement approved in writing by the Originator or the omission or
the alleged omission to state therein a material fact necessary in order to make
the statements in the Prospectus Supplement or any amendment or supplement to
the Prospectus Supplement approved in writing by the Originator, in the light of
the circumstances under which they were made, not misleading, but only to the
extent that such untrue statement or alleged untrue statement or omission or
alleged omission relates to the Originator Information contained in the
Prospectus Supplement, (ii) any untrue statement or alleged untrue statement of
any material fact contained in the information on any computer tape furnished to
the Purchaser or an affiliate thereof by or on behalf of the Originator
containing information regarding the assets of the Trust or (iii) any untrue
statement or alleged untrue statement of any material fact contained in any
information provided by the Originator to the Purchaser or any affiliate
thereof, or any material omission from the information purported to be provided
hereby, and disseminated to PricewaterhouseCoopers LLP or prospective investors
(directly or indirectly through available information systems) in connection
with the issuance, marketing or offering of the Certificates. This indemnity
agreement will be in addition to any liability which the Originator may
otherwise have.

                   (b) The Purchaser agrees to indemnify and hold harmless the
Seller and the Originator, each of their respective officers, directors and each
person or entity who controls the Seller, the Originator or any such person,
against any and all losses, claims, damages or liabilities, joint and several,
to which the Seller, the Originator or any such person or entity may become
subject, under the Securities Act or otherwise, and will reimburse the Seller
and/or the Originator for any legal or other expenses incurred by the Seller,
the Originator, each such officer and director and such controlling person in
connection with investigating or defending any such losses, claims, damages or
liabilities insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Prospectus
Supplement or any amendment or supplement to the Prospectus Supplement or the
omission or the alleged omission to state therein a material fact necessary in
order to make the statements in the Prospectus Supplement or any amendment or
supplement to the Prospectus Supplement, in the light of the circumstances under
which they were made, not misleading, but only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission is not
contained in the Originator Information in the Prospectus Supplement. This
indemnity agreement will be in addition to any liability which the Purchaser may
otherwise have.

                                       18

<PAGE>

                   (c) Promptly after receipt by any indemnified party under
this Article V of notice of any claim or the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article V.

          If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Article V for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation.

          Any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article V consist of the Purchaser, by the Originator, if the
indemnified parties in this Article V consist of the Originator, or by the
Seller, if the indemnified parties under this Article V consist of the Seller.

          Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to consent

                                       19

<PAGE>

to a settlement of any action, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and the indemnifying party has not
previously provided the indemnified party with written notice of its objection
to such settlement. No indemnifying party shall effect any settlement of any
pending or threatened proceeding in respect of which an indemnified party is or
could have been a party and indemnity is or could have been sought hereunder,
without the written consent of such indemnified party, unless settlement
includes an unconditional release of such indemnified party from all liability
and claims that are the subject matter of such proceeding.

                   (d) In order to provide for just and equitable contribution
in circumstances in which the indemnity agreement provided for in this Article
is for any reason held to be unenforceable although applicable in accordance
with its terms, the Seller and the Originator, on the one hand, and the
Purchaser, on the other, shall contribute to the aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by said indemnity
agreement incurred by the Seller, the Originator and the Purchaser in such
proportions as shall be appropriate to reflect the relative benefits received by
the Seller and the Originator on the one hand and the Purchaser on the other
from the sale of the Mortgage Loans such that the Purchaser is responsible for
the lesser of (i) 0.25% thereof and (ii) 0.25% of the aggregate proceeds to the
Seller from the sale of the Mortgage Loans and the Originator shall be
responsible for the balance; PROVIDED, HOWEVER, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section, each
officer and director of the Purchaser and each person, if any, who controls the
Purchaser within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Purchaser, each director of the Originator,
each officer of the Originator, and each person, if any, who controls the
Originator within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Originator and each director of the Seller,
each officer of the Seller, and each person, if any, who controls the Seller
within the meaning of Section 15 of the Securities Act shall have the same
rights to contribution as the Seller.

                   (e) The Originator agrees to indemnify and to hold each of
the Purchaser, the Trustee, each of the officers and directors of each such
entity and each person or entity who controls each such entity or person and
each Certificateholder harmless against any and all claims, losses, penalties,
fines, forfeitures, legal fees and related costs, judgments, and any other
costs, fees and expenses that the Purchaser, the Trustee, or any such person or
entity and any Certificateholder may sustain in any way (i) related to the
failure of the Originator to perform its duties in compliance with the terms of
this Agreement, (ii) arising from a breach by the Originator of its
representations and warranties in Section 3.01, 3.02 or 3.03 of this Agreement
or (iii) related to the origination or prior servicing of the Mortgage Loans by
reason of any acts, omissions, or alleged acts or omissions of the Originator,
the Seller or any servicer. The Originator shall immediately notify the
Purchaser, the Trustee and each Certificateholder if a claim is made by a third
party with respect to this Agreement. The Originator shall assume the defense of
any such claim and pay all expenses in connection therewith, including
reasonable counsel fees, and promptly pay, discharge and satisfy any judgment or
decree which may be entered against the Purchaser, the Trustee or any such
person or entity and/or any Certificateholder in respect of such claim.

          Section 6.01 TERMINATION. The respective obligations and
responsibilities of the Originator, the Seller and the Purchaser created hereby
shall terminate, except for the Originator's indemnity obligations as provided
herein upon the termination of the Trust as provided in Article X of the Pooling

          if to the Seller:

                   Option One Owner Trust 2001-2
                   c/o Wilmington Trust Company
                   One Rodney Square North
                   1100 North Market Street
                   Wilmington, Delaware 19890
                   Attention: Corporate Trust Administration

or such other address as may hereafter be furnished to the Originator and the
Purchaser in writing by the Seller.

          Section 7.04 SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions of terms of this Agreement shall be held
invalid for any reason whatsoever, 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 of
enforceability of the other provisions of this Agreement.

          Section 7.05 COUNTERPARTS. This Agreement may be executed in one or
more counterparts and by the different parties hereto on separate counterparts,
each of which, when so executed, shall be deemed to be an original and such
counterparts, together, shall constitute one and the same agreement.

          Section 7.06 FURTHER AGREEMENTS. The Purchaser, the Seller and the
Originator each agree to execute and deliver to the other such additional
documents, instruments or agreements as may be necessary or reasonable and
appropriate to effectuate the purposes of this Agreement or in connection with
the issuance of any series of Certificates representing interests in the
Mortgage Loans.

          Without limiting the generality of the foregoing, as a further
inducement for the Purchaser to purchase the Mortgage Loans from the Seller, the
Originator will cooperate with the Purchaser in connection with the sale of any
of the securities representing interests in the Mortgage Loans. In that
connection, the Originator will provide to the Purchaser any and all information
and appropriate verification of information, whether through letters of its
auditors and counsel or otherwise, as the Purchaser shall reasonably request and
will provide to the Purchaser such additional representations and warranties,
covenants, opinions of counsel, letters from auditors, and certificates of
public officials or officers of the Originator as are reasonably required in
connection with such transactions and the offering of investment grade
securities rated by the Rating Agencies.

          Section 7.07 INTENTION OF THE PARTIES. It is the intention of the
parties that the Purchaser is purchasing, and the Seller is selling, the
Mortgage Loans rather than pledging the Mortgage Loans to secure a loan by the
Purchaser to the Seller. Accordingly, the parties hereto each intend to treat
the transaction for federal income tax purposes and all other purposes as a sale
by the Seller, and a purchase by the Purchaser, of the Mortgage Loans. The
Purchaser will have the right to review the Mortgage Loans and the related
Mortgage Files to determine the characteristics of the Mortgage Loans which will
affect the federal income tax consequences of owning the Mortgage Loans and the

                                       22

<PAGE>

Seller will cooperate with all reasonable requests made by the Purchaser in the
course of such review.

          Section 7.08 SUCCESSORS AND ASSIGNS, ASSIGNMENT OF PURCHASE AGREEMENT.
This Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Originator, the Purchaser, the Trustee and the NIMs Insurer. The
NIMs Insurer shall be a third party beneficiary hereof and may enforce the terms
hereof as if a party hereto. The obligations of the Seller and the Originator
under this Agreement cannot be assigned or delegated to a third party without
the consent of the Purchaser which consent shall be at the Purchaser's sole
discretion, except that the Purchaser acknowledges and agrees that the Seller or
the Originator may assign its obligations hereunder to any Person into which the
Seller or the Originator is merged or any corporation resulting from any merger,
conversion or consolidation to which the Seller or the Originator is a party or
any Person succeeding to the business of the Seller or the Originator. The
parties hereto acknowledge that the Purchaser is acquiring the Mortgage Loans
for the purpose of contributing them to a trust that will issue a series of
Certificates representing undivided interests in such Mortgage Loans. As an
inducement to the Purchaser to purchase the Mortgage Loans, the Seller and the
Originator each acknowledge and consent to the assignment by the Purchaser to
the Trustee of all of the Purchaser's rights against the Seller and the
Originator pursuant to this Agreement insofar as such rights relate to Mortgage
Loans transferred to the Trustee and to the enforcement or exercise of any right
or remedy against the Seller or the Originator pursuant to this Agreement by the
Trustee. Such enforcement of a right or remedy by the Trustee shall have the
same force and effect as if the right or remedy had been enforced or exercised
by the Purchaser directly.

          Section 7.09 SURVIVAL. The representations and warranties set forth in
Sections 3.01, 3.02 and 3.03 and the provisions of Article V hereof shall
survive the purchase of the Mortgage Loans hereunder.

          Section 7.10 OWNER TRUSTEE. It is expressly understood and agreed by
the parties to this Agreement that (a) this Agreement is executed and delivered
by Wilmington Trust Company, not individually or personally but solely as Owner
Trustee of the Seller, in the exercise of the powers and authority conferred and
vested in it as trustee, (b) each of the representations, undertakings and
agreements herein made on the part of the Seller is made and intended not as
personal representations, undertakings and agreements by Wilmington Trust
Company but is made and intended for the purpose of binding only the Seller, (c)
nothing herein contained shall be construed as creating any liability on
Wilmington Trust Company, individually or personally, to perform any covenant
either expressed or implied contained herein, all such liability, if any, being
expressly waived by the parties to this Agreement and by any person claiming by,
through or under the parties to this Agreement and (d) under no circumstances
shall Wilmington Trust Company be personally liable for the payment of any
indebtedness or expenses of the Seller or be liable for the breach or failure of
any obligation, representation, warranty or covenant made or undertaken by the
Seller under this Agreement or any other document.

          FAS 140 P &S RELEVANT PROVISIONS - RECOVERY FOR DEFAULT LOANS

COLLECTIONS DEPARTMENT PRE-FORECLOSURE PROCESS:
----------------------------------------------

At 33 calendar days delinquent, all borrowers are sent a 30-day pre-foreclosure
demand letter. Borrowers in states that require more than a 30-day period are
given the amount of time specified by state law.

Borrowers who are unable to pay the total amount past due are reviewed for
foreclosure based upon the following criteria:

     "Early Indicator" default risk score. Those borrowers with risk scores that
suggest a strong statistical likelihood of continuing default, are approved for
foreclosure as soon as 48 hours after expiration of the demand letter
(approximately 64 calendar days delinquent).

     A.   Moderate risk with willingness and ability. Those borrowers with a
          moderate statistical likelihood of continuing default who demonstrate
          a willingness and ability to pay (as defined above), are solicited for
          extended (up to 6 months) repayment plans in which a portion of all
          past due payments are divided equally by 6 and a monthly payment
          schedule is established which consists of a "good faith" payment of
          some portion of the past due amount, one regular monthly installment
          and 1/6th of the remaining past due amount.

     B.   Low risk with willingness and ability. Those borrowers with a low risk
          of continuing default are actively solicited for placement on a
          repayment plan and/or are granted additional time to resolve their
          financial difficulties informally in arrangement with a loan
          counselor. Foreclosure is not typically initiated if or until the loan
          becomes 90+ days delinquent and the borrower is unable or unwilling to
          continue to make reasonable repayment arrangements.

     C.   Broken repayment plans. Those borrowers who are placed on extended
          repayment plans but fail to make their scheduled payments, are
          approved for foreclosure as soon as 48 hours after the payment plan is
          broken.

All borrowers are given all reasonable opportunities to pay the total amount
past due (including all contractually permitted fees and charges) prior to the
expiration of the 30 day demand letters. Borrowers who fail to contact Option
One collections when past due, who repeatedly break promises to pay, who have a
willingness but no financial ability, or apparent financial ability but no
willingness, may be referred to foreclosure at any time after the expiration of
the 30-day demand letter, without regard to any other factor, but as a general
rule, a loan is referred to foreclosure no later than the 120th day of
delinquency. The guidelines outlined herein presuppose at least some reasonable
degree of willingness and ability.

PRE-CONVEYANCE OF TITLE:
-----------------------

Initial contact is made for discovery of mortgagor's intent and a minimum
requirement of two attempted contacts per month is required. In general, contact
made or attempted within the first 48 hours establishes categories as follows:
Willingness and Ability, No Willingness or Willingness and No Ability. Each
category provides a subset of options for loss mitigation efforts and the
options are ranked within each category as follows:

     1.   WILLINGNESS AND ABILITY-- Typically the mortgagor(s) reason for
          default is temporary and a foreseeable solution is probable. The
          standard options negotiated, ranked in priority are:

          A.  Full Reinstatement
          B.  Payoff
          C.  Standard 6 month payment plan
          D.  Extension of the payment plan
          E.  Forbearance
          F.  Pre-Sale/Pre-Foreclosure Sale
          G.  Short Payoff
          H.  Modification

     2.   NO WILLINGNESS -- Typically the mortgagor(s) is unclear of options to
          mitigate default and avoidsall calls or is brief and discloses little
          when contact is made. In this category efforts are made to continue
          attempts to contact and/or counsel mortgagor(s). When no contact is
          made, Skip Tracing, promotional items and/or letters are mailed in
          attempts to stimulate communication.

     3.   WILLINGNESS AND NO ABILITY -- Mortgagor(s) want to save home or remedy
          the default, however do not have resources to do so. In this scenario,
          the standard options negotiated, ranked in priority are:

          A.  Payoff
          B.  Assumption
          C.  Pre-Sale/Pre-Foreclosure Sale
          D.  Short Payoff
          E.  Deed In Lieu of Foreclosure
          F.  Write-Off
          G.  Modification

Foreclosure process is also running parallel to the Loss Mitigation efforts and
in the event no workout is achieved then the Master Servicer obtains title
through foreclosure sale, from which the REO Department will attempt to seek
complete recovery from the sale of said property.

List of All Loss Mitigation Options Used:
----------------------------------------
        -   Full Reinstatement

        -   Assumption
        -   Modification
        -   Deed In Lieu of Foreclosure
        -   Write-off

CONVEYANCE OF TITLE:
-------------------

Once title is acquired as a result of foreclosure sale, Deed In Lieu of
Foreclosure or otherwise, the property is assigned to an REO Agent for complete
and timely disposition. REO Broker/Agents are selected and retained using the
following criteria:

        -   Experience
        -   Possess Error and Omissions Insurance
        -   Licensed to sell Real Property in the related region
        -   Adhere to Option One Mortgage Corporation's Standards

Review of the current values obtained on the subject property will determine the
marketing strategy and the strategy will focus on disposing of the property in a
timely and practical manner. An analysis worksheet is completed to establish the
marketing strategy on the property.

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 Class R Certificates (the "Certificate") issued pursuant
to the Pooling and Servicing Agreement (the "Agreement"), relating to the
above-referenced Certificates, among Option One Mortgage Acceptance Corporation,
as Depositor, Option One Mortgage Corporation, as Master Servicer (the "Master
Servicer") and Wells Fargo Bank Minnesota, N.A., as Trustee (the "Trustee").
Capitalized terms used, but not defined herein shall have the meanings ascribed
to such terms in the Agreement. The Transferee has authorized the undersigned to
make this affidavit on behalf of the Transferee.

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

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

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

                                       K-1

<PAGE>

cooperatives and, except as may be provided in Treasury Regulations, persons
holding interests in pass-through entities as a nominee for another Person.)

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

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

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

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

          9. The Transferee is a United States Person as defined in the
Agreement.

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

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