Value, the Trust may request that the Initial Noteholder advance Additional Note
Principal Balances equal to such increase in the Collateral Value of the related
Mortgage Loans and the Initial Noteholder may, in its sole discretion, make such
advance of Additional Note Principal Balances. Pursuant to and subject to the
Note Purchase Agreement, the Trust shall request that the Initial Noteholder
advance on each Funding Date Additional Note Principal Balances equal to the
Additional Note Balance to be purchased by the Trust on such date and the
Initial Noteholder shall remit on such Funding Date to the Funding Account an
amount equal to such Additional Note Principal Balance.

                  (ii) Notwithstanding anything to the contrary herein, in no
event shall the Initial Noteholder be required to advance Additional Note
Principal Balances on a Transfer Date or Collateral Value Increase Date if the
conditions precedent with respect to such Transfer Date or Collateral Value Date
under Section 2.06(a) and the conditions precedent to the purchase of Additional
Note Principal Balances set forth in Section 3.01 of the Note Purchase Agreement
have not been fulfilled. Notwithstanding anything to the contrary herein, in no
event shall the Initial Noteholder be required to advance Additional Note
Principal Balances on a Funding Date if the conditions precedent with respect to
such Funding Date under Section 2.06(b), the conditions precedent to the
purchase of Additional Note Principal Balances set forth in Section 3.02 of the
Note Purchase Agreement and the conditions precedent to the purchase of
Additional Principal Balances set forth in Section 3.01 of the Advance Note
Purchase Agreement have not been fulfilled.

                  (iii) The Servicer shall appropriately note such Additional
Note Principal Balance (and the increased Note Principal Balance) in the next
succeeding Payment Statement; provided, however, that failure to make any such
notation in such Payment Statement or any error in such notation shall not
adversely affect any Noteholder's rights with respect to its Note Principal
Balance and its right to receive interest and principal payments in respect of
the Note Principal Balance held by such Noteholder. The Initial Noteholder shall
record on the schedule attached to such Noteholder's Note, the date and amount
of any Additional Note Principal Balance advanced by it; provided, that failure
to make such recordation on such schedule or any error in such schedule shall
not adversely affect any Noteholder's rights with respect to its Note Principal
Balance and its right to receive interest payments in respect of the Note
Principal Balance held by such Noteholder.

                  (iv) Absent manifest error, the Note Principal Balance of each
Note as set forth in the Initial Noteholder's records shall be binding upon the
Noteholders and the Trust, notwithstanding any notation made by the Servicer in
its Payment Statement pursuant to the preceding paragraph.

      Section 2.02 Ownership and Possession of Loan Files.

      With respect to each Loan, as of the related Transfer Date the ownership
of the related Promissory Note, the related Mortgage and the contents of the

      Section 2.03 Books and Records; Intention of the Parties.

            (a) As of each Transfer Date, the sale of each of the Loans and
Residual Securities conveyed by the Depositor on such Transfer Date shall be
reflected on the balance sheets and other financial statements of the Depositor
and the Loan Originator, as the case may be, as a sale of assets and a
contribution to capital by the Loan Originator and the Depositor, as applicable,
under GAAP. Each of the Servicer and the Custodian shall be responsible for
maintaining, and shall maintain, a complete set of books and records for each
Loan and Residual Security which shall be clearly marked to reflect the
ownership of each Loan or Residual Security, as of the related Transfer Date, by
the Issuer and for the benefit of the Securityholders.

            (b) It is the intention of the parties hereto that, other than for
federal, state and local income or franchise tax purposes, the transfers and
assignments of the Trust Estate on the initial Closing Date, on each Transfer
Date and as otherwise contemplated by the Basic Documents and the Assignments
shall constitute a sale of the Loans, Residual Securities and all related
property from the Depositor to the Issuer and such property shall not be
property of the Depositor. It is the intention of the parties hereto that, other
than for federal, state and local income or franchise tax purposes, the
transfers and assignments on each Funding Date shall constitute a sale of the
Advance Note, the related Additional Note Balances and all related property from
the Advance Trust to the Issuer and such property shall not be property of the
Advance Depositor or the Receivables Seller. The parties hereto shall treat the
Notes as indebtedness for federal, state and local income and franchise tax
purposes.

            (c) If any of the assignments and transfers of the Loans or the
Residual Securities and the other property of the Trust Estate specified in
Section 2.01(a) hereof to the Issuer pursuant to this Agreement or the
conveyance of the Loans or the Residual Securities or any of such other property
of the Trust Estate to the Issuer, other than for federal, state and local
income or franchise tax purposes, is held or deemed not to be a sale or is held
or deemed to be a pledge of security for a loan, the Depositor intends that the
rights and obligations of the parties shall be established pursuant to the terms
of this Agreement and that, in such event, with respect to such property, (i)
consisting of Loans or Residual Securities and related property, the Depositor
shall be deemed to have granted, as of the related Transfer Date, to the Issuer
a first priority security interest in the entire right, title and interest of
the Depositor in and to such Loans or Residual Securities and proceeds and all
other property conveyed to the Issuer as of such Transfer Date, (ii) consisting
of any other property specified in Section 2.01(a), the Depositor shall be
deemed to have granted, as of the initial Closing Date, to the Issuer a first
priority security interest in the entire right, title and interest of the
Depositor in and to such property and the proceeds thereof. In such event, with
respect to such property, this Agreement shall constitute a security agreement
under applicable law.

            (d) On the Closing Date, the Depositor shall, at such party's sole
expense, cause to be filed UCC-1 Financing Statements naming the Issuer as
"secured party" and describing the Trust Estate being sold by the Depositor to
the Issuer with the appropriate governmental filing office in the state in which
the Depositor is organized and any other jurisdictions as shall be necessary to
perfect a security interest in the Trust Estate. In addition, on the Closing
Date, the Loan Originator shall, at its expense, cause to be filed UCC-1
Financing Statements naming the Depositor as "secured party" and describing the
Loans being sold by the

                                       33

<PAGE>

Loan Originator to the Depositor with the appropriate governmental office in the
state in which the Loan Originator is organized and such other jurisdictions as
shall be necessary to perfect a security interest in the Trust Estate. In
addition, on the Closing Date, the Depositor shall, at its expense, cause to be
filed UCC-1 Financing Statements naming the Depositor as "secured party" and
describing the Loans being sold by the Loan Originator to the Depositor with the
appropriate governmental office in the state in which the Loan Originator is
organized and such other jurisdictions as shall be necessary to perfect a
security interest in the Trust Estate. On or before the initial Funding Date,
the Issuer shall, at its expense, cause to be filed UCC-1 Financing Statements
naming the Issuer as "secured party" and describing the Advance Note being sold
by the Advance Trust to the Issuer with the appropriate governmental office in
the state in which the Advance Trust is organized and such other jurisdictions
as shall be necessary to perfect a security interest in the Trust Estate. On or
before the initial Transfer Date with respect to Residual Securities, the Issuer
shall, at its expense, cause to be filed UCC-1 Financing Statements naming the
Issuer as "secured party" and describing each Residual Security being sold by
the Advance Trust to the Issuer with the appropriate governmental office in the
state of Delaware and such other jurisdictions as shall be necessary to perfect
a security interest in the Trust Estate.

      Section 2.04 Delivery of Loan Documents.

            (a) The Loan Originator shall, prior to the related Transfer Date

are provided to the Loan Originator by the Initial Noteholder on behalf of the
Issuer, such funds shall be promptly returned to the Initial Noteholder on
behalf of the Issuer and (ii) in the event that any Wet Funded Loan is subject
to a recission, all funds received in connection with such recission shall be
promptly returned to the Initial Noteholder on behalf of the Issuer. With
respect to each Residual Security, the Loan Originator shall, prior to the
related Transfer Date, deliver or cause to be delivered to the Indenture trustee
a Residual Security Schedule and each of the related Loan Documents and shall

File Delivery Date), deliver or cause to be delivered to the Servicer the
related Servicer's Loan File (i) for the benefit of, and as agent for, the
Noteholders and (ii) for the benefit of the Indenture Trustee, on behalf of the
Noteholders, for so long as the Notes are outstanding; after the Notes are not
outstanding, the Servicer's Loan File shall be held in the custody of the
Servicer for the benefit of, and as agent for, the Certificateholders.

            (c) The Indenture Trustee shall cause the Custodian to take and
maintain continuous physical possession of the Custodial Loan Files in the State

to hold the Custodial Loan Files and any additions, amendments, replacements or
supplements to the documents contained therein, as well as any other assets
included in the Trust Estate and delivered to the Custodian, in trust, upon and
subject to the conditions set forth herein. The Indenture Trustee further agrees
to cause the Custodian to execute and deliver such certifications as are
required under the Custodial Agreement and to otherwise direct the Custodian to
perform all of its obligations with respect to the Custodial Loan Files in
strict accordance with the terms of the Custodial Agreement.

            (b)   (i) With respect to any Loans which are set forth as
exceptions in the Exceptions Report, the Loan Originator shall cure such
exceptions by delivering such missing documents to the Custodian or otherwise
curing the defect no later than, in the case of (x) a non-Wet Funded Loan, 5
Business Days, or (y) in the case of a Wet Funded Loan one Business Day after
the Wet Funded Custodial File Delivery Date, in each case, following the receipt
of the first Exceptions Report listing such exception with respect to such Loan.

                  (ii) In the event that, with respect to any Loan, the Loan
Originator does not comply with the document delivery requirements of this
Section 2.05 and such failure has a material adverse effect on the value or
enforceability of any Loan or the interests of the Securityholders in any Loan,
the Loan Originator shall repurchase such Loan within one Business Day of notice
thereof from the Indenture Trustee or the Initial Noteholder at the Repurchase
Price thereof with respect to such Loan by depositing such Repurchase Price in

comply with the foregoing delivery requirements.

            (c) In performing its reviews of the Custodial Loan Files pursuant
to the Custodial Agreement, the Custodian shall have no responsibility to
determine the genuineness of any document contained therein and any signature
thereon. The Custodian shall not have any responsibility for determining whether

by it to hold the Servicer's Loan File as herein provided and shall promptly
take appropriate action to remedy any such failure. In acting as custodian of
such documents and instruments, the Servicer agrees not to assert any legal or
beneficial ownership interest in the Loans or such documents or instruments.

Exchange Act of 1934, as amended for any and all liabilities, obligations,
losses, damages, payments, costs or expenses of any kind whatsoever which may be
imposed on, incurred by or asserted against the Securityholders or the Indenture
Trustee as the result of the negligence or willful misfeasance by the Servicer
relating to the maintenance and custody of such documents or instruments which
have been delivered to the Servicer; provided, however, that the Servicer will
not be liable for any portion of any such amount resulting from the negligence
or willful misconduct of any Securityholders or the Indenture Trustee; and
provided, further, that the Servicer will not be liable for any portion of any
such amount resulting from the Servicer's compliance with any instructions or
directions consistent with this Agreement issued to the Servicer by the
Indenture Trustee or the Majority Noteholders. The Indenture Trustee shall have
no duty to monitor or otherwise oversee the Servicer's performance as custodian
of the Servicer Loan File hereunder.

under each Basic Document to which it is a party;

            (b) The execution and delivery by the Depositor of each Basic
Document to which the Depositor is a party and its performance of and compliance
with all of the terms thereof will not violate the Depositor's organizational
documents or constitute a default (or an event which, with notice or lapse of
time, or both, would constitute a default) under, or result in the breach or
acceleration of, any material contract, agreement or other instrument to which
the Depositor is a party or which are applicable to the Depositor or any of its
assets;

Depositor is a party, has duly authorized the execution, delivery and
performance of each Basic Document to which it is a party and has duly executed

enforceability of, any Basic Document to which it is a party or the Securities,
provided, however, that for purposes of calculating whether the Loan Seller
satisfies the Financial Covenants, such action, proceeding or investigation
shall not be taken into account unless there is a reasonable possibility of an
adverse determination of such action, proceeding or investigation;

            (f) No consent, approval, authorization or order of any court or
governmental agency or body is required for: (1) the execution, delivery and

of the Basic Documents to which it is a party or delivered pursuant thereto,

            (n) The Loan Originator's principal place of business and chief

hereto.

      It is understood and agreed that the representations and warranties set
forth in this Section 3.02 shall survive delivery of the respective Custodial
Loan Files to the Custodian (as the agent of the Indenture Trustee) and shall
inure to the benefit of the Securityholders, the Depositor, the Servicer, the
Indenture Trustee, the Owner Trustee and the Issuer. Upon discovery by the Loan

<PAGE>

any Loan or Residual Security or the interests of the Securityholders in any

of the representations and warranties contained in this Section 3.02. The fact
that the Initial Noteholder has conducted or has failed to conduct any partial
or complete due diligence investigation of the Loan Files shall not affect the
Securityholders rights to demand repurchase or substitution as provided under
this Agreement.

      Section 3.03 Representations, Warranties and Covenants of the Servicer.

      The Servicer hereby represents and warrants to and covenants with the

Document to which it is a party and its performance of and compliance with the
terms thereof will not violate the Servicer's articles of incorporation or

acceleration of, any material contract, agreement or other instrument to which
the Servicer is a party or which are applicable to the Servicer or any of its
assets;

            (c) The Servicer has the full power and authority to enter into and

rights of creditors generally, and by general equity principles (regardless of
whether such enforcement is considered in a proceeding in equity or at law);

            (d) The Servicer is not in violation of, and the execution and

of, the Servicer currently pending with regard to which the Servicer has
received service of process and no action or proceeding against, or
investigation of, the Servicer is, to the knowledge of the Servicer, threatened

which it is a party or (C) if determined adversely to the Servicer, would
reasonably be expected to prohibit or materially and adversely affect the
performance by the Servicer of its obligations under, or the validity or
enforceability of, any Basic Document to which it is a party or the Securities,
provided, however, that for the purpose of calculating whether the Servicer
satisfies the Financial Covenants, such action, proceeding or investigation
shall not be taken into account unless there is a reasonable possibility of an
adverse determination of such action, proceeding or investigation;

            (f) No consent, approval, authorization or order of any court or
governmental agency or body is required for the execution, delivery and
performance by the Servicer of, or compliance by the Servicer with, any Basic
Document to which it is a party or the Securities, or for the consummation of
the transactions contemplated by any Basic Document to which it is a party,
except for such consents, approvals, authorizations and orders, if any, that
have been obtained prior to such date;

            (g) The information, reports, financial statements, exhibits and
schedules furnished in writing by or on behalf of the Servicer to the Initial
Noteholder in connection with the negotiation, preparation or delivery of the
Basic Documents to which it is a party or delivered pursuant thereto, when taken

result of the performance of its obligations pursuant to under the Basic
Documents to which it is a party;

            (i) The Servicer acknowledges and agrees that the Servicing

Eligible Servicer or, if not an Eligible Servicer, each Subservicer is an
Eligible Servicer and the Servicer covenants to cause each Subservicer to be an
Eligible Servicer.

      It is understood and agreed that the representations, warranties and
covenants set forth in this Section 3.03 shall survive delivery of the
respective Custodial Loan Files to the Indenture Trustee or the Custodian on its
behalf and shall inure to the benefit of the Depositor, the Securityholders, the
Indenture Trustee and the Issuer. Upon discovery by the Loan Originator, the
Depositor, the Servicer, the Indenture Trustee, the Owner Trustee or the Issuer
of a breach of any of the foregoing representations, warranties and covenants
that materially and adversely affects the value of any Loan or Residual Security
or the interests of the Securityholders therein or in the Securities, the party
discovering such breach shall give prompt written notice (but in no event later

rights to exercise their remedies as provided under this Agreement.

      Section 3.04 Reserved.

      Section 3.05 Representations and Warranties Regarding Loans.

      The Loan Originator makes each of the representations and warranties set
forth on Exhibit E hereto with respect to each Loan and makes each
representation and warranty set forth in Section 3 of the Residual Securities
Transfer Agreement with respect to each Residual Security, provided, however,
that with respect to each Loan transferred to the Issuer by a QSPE Affiliate, to
the extent that the Loan Originator has at the time of such transfer actual
knowledge of any facts or circumstances that would render any of such
representations and warranties materially false, the Loan Originator shall
notify the Initial Noteholder of such facts or circumstances and, in such event,
shall have no obligation to make such materially false representation and
warranty.

      In addition, the Loan Originator represents and warrants with respect to
each Loan sold by a QSPE Affiliate that the Loan Originator has not been
required to pay any amount to or on behalf of such QSPE Affiliate that lowered
the recourse to the Loan Originator available to such QSPE Affiliate below the
maximum recourse to the Loan Originator available to such QSPE Affiliate under
the terms of any loan purchase agreement providing for recourse by that QSPE
Affiliate to the Loan Originator.

      Section 3.06 Purchase and Substitution.

            (a) It is understood and agreed that the representations and
warranties set forth in Exhibit E hereto and in Section 3 of the Residual
Securities Transfer Agreement shall survive the conveyance of the Loans or the
Residual Securities to the Indenture Trustee on behalf of the Issuer, and the
delivery of the Securities to the Securityholders. Upon discovery by the
Depositor, the Servicer, the Loan Originator, the Custodian, the Issuer, the
Indenture Trustee or any Securityholder of a breach of any of such
representations and warranties or the representations and warranties of the Loan
Originator set forth in Section 3.02 which materially

                                       47

<PAGE>

and adversely affects the value or enforceability of any Loan or Residual
Security or the interests of the Securityholders in any Loan or Residual
Security (notwithstanding that such representation and warranty was made to the
Loan Originator's best knowledge) or which, as a result of the attributes of the
aggregate Loan Pool or Residual Securities Pool, constitutes a breach of the
representations and warranties set forth in Exhibit E or in Section 3 of the
Residual Securities Transfer Agreement, the party discovering such breach shall
give prompt written notice to the others. The Loan Originator shall within 5
Business Days of the earlier of the Loan Originator's discovery or the Loan
Originator's receiving notice of any breach of a representation or warranty,
promptly cure such breach in all material respects. If within 5 Business Days
after the earlier of the Loan Originator's discovery of such breach or the Loan
Originator's receiving notice thereof such breach has not been remedied by the
Loan Originator and such breach materially and adversely affects the interests
of the Securityholders in the related Loan (an "Unqualified Loan") or related
Residual Security (an "Unqualified Residual Security"), the Loan Originator
shall promptly upon receipt of written instructions from the Majority
Noteholders either (i) remove such Unqualified Loan (in which case it shall
become a Deleted Loan) or Unqualified Residual Security (in which case it shall
become a Deleted Residual Security) from the Trust and substitute one or more
Qualified Substitute Loans (in place of a Deleted Loan) or Qualified Residual
Securities (in place of a Deleted Residual Security) in the manner and subject
to the conditions set forth in this Section 3.06 or (ii) purchase such
Unqualified Loan or Unqualified Residual Security at a purchase price equal to
the Repurchase Price with respect to such Unqualified Loan or Unqualified
Residual Security by depositing or causing to be deposited such Repurchase Price
in the Collection Account.

      Any substitution of Loans or Residual Securities pursuant to this Section
3.06(a) shall be accompanied by payment by the Loan Originator of the
Substitution Adjustment, if any, (x) if no Overcollateralization Shortfall
exists on the date of such substitution (after giving effect to such
substitution), remitted to the Noteholders in accordance with Section
5.01(c)(4)(i) or (y) otherwise to be deposited in the Collection Account
pursuant to Section 5.01(b)(1) hereof.

            (b) As to any Deleted Loan or Deleted Residual Security for which
the Loan Originator substitutes a Qualified Substitute Loan or Loans or
Qualified Substitute Residual Security or Residual Securities, the Loan
Originator shall effect such substitution by delivering to the Indenture Trustee
and Initial Noteholder a certification executed by a Responsible Officer of the
Loan Originator to the effect that the Substitution Adjustment, if any, has been
(x) if no Overcollateralization Shortfall exists on the date of such
substitution (after giving effect to such substitution), remitted to the
Noteholders in accordance with Section 5.01(c)(4)(i), or (y) otherwise deposited
in the Collection Account. As to any Deleted Loan for which the Loan Originator
substitutes a Qualified Substitute Loan or Loans, the Loan Originator shall
effect such substitution by delivering to the Custodian the documents
constituting the Custodial Loan File for such Qualified Substitute Loan or
Loans. As to any Deleted Residual Security for which the Loan Originator
substitutes a Qualified Substitute Residual Security or Residual Securities, the
Loan Originator shall effect such substitution by delivering to the Trustee the
Loan Documents for such Qualified Substitute Residual Security or Residual
Securities.

      The Servicer shall deposit in the Collection Account all payments received
in connection with each Qualified Substitute Loan or Qualified Substitute
Residual Security after the date of such substitution. Monthly Payments received
with respect to Qualified Substitute Loans or

                                       48

<PAGE>

Qualified Substitute Residual Securities on or before the date of substitution
will be retained by the Loan Originator. The Trust will be entitled to all
payments received on the Deleted Loan or Deleted Residual Security on or before
the date of substitution and the Loan Originator shall thereafter be entitled to
retain all amounts subsequently received in respect of such Deleted Loan or
Residual Security. The Loan Originator shall give written notice to the Issuer,
the Servicer (if the Loan Originator is not then acting as such), the Indenture
Trustee and Initial Noteholder that such substitution has taken place and the
Servicer shall amend the Loan Schedule or Residual Security Schedule, as
applicable, to reflect (i) the removal of such Deleted Loan or Deleted Residual
Security from the terms of this Agreement and (ii) the substitution of the
Qualified Substitute Loan or Qualified Substitute Residual Security. The
Servicer shall promptly deliver to the Issuer, the Loan Originator, the
Indenture Trustee and Initial Noteholder, a copy of the amended Loan Schedule
and/or a copy of the amended Residual Security Schedule. Upon such substitution,
such Qualified Substitute Loan or Loans or Qualified Substitute Residual
Security or Residual Securities shall be subject to the terms of this Agreement
in all respects, and the Loan Originator shall be deemed to have made with
respect to such Qualified Substitute Loan or Loans, as of the date of
substitution, the covenants, representations and warranties set forth in Exhibit
E hereto and with respect to such or Qualified Substitute Residual Security or
Residual Securities, the covenants, representations and warranties set forth in
the Residual Securities Transfer Agreement. On the date of such substitution,
the Loan Originator will (x) if no Overcollateralization Shortfall exists as of
the date of substitution (after giving effect to such substitution), remit to
the Noteholders as provided in Section 5.01(c)(4)(i) or (y) otherwise deposit
into the Collection Account, in each case an amount equal to the related
Substitution Adjustment, if any. In addition, on the date of such substitution,
the Servicer shall cause the Indenture Trustee to release the Deleted Loan or
Deleted Residual Securities from the lien of the Indenture and the Servicer will
cause such Qualified Substitute Loan or Qualified Substitute Residual Securities
to be pledged to the Indenture Trustee under the Indenture as part of the Trust
Estate.

            (c) With respect to all Unqualified Loans, Unqualified Residual
Securities or other Loans or Residual Securities repurchased by the Loan
Originator pursuant to this Agreement, upon the deposit of the Repurchase Price
therefor into the Collection Account, (i) the Issuer shall assign to the Loan
Originator, without representation or warranty, all of the Issuer's right, title
and interest in and to such Unqualified Loan or Unqualified Residual Security,
which right, title and interest were conveyed to the Issuer pursuant to Section
2.01 hereof and (ii) the Indenture Trustee shall assign to the Loan Originator,
without recourse, representation or warranty, all the Indenture Trustee's right,
title and interest in and to such Unqualified Loans or Loans or Unqualified
Residual Security or Residual Securities, which right, title and interest were
conveyed to the Indenture Trustee pursuant to Section 2.01 hereof and the
Indenture. The Issuer and the Indenture Trustee shall, at the expense of the
Loan Originator, take any actions as shall be reasonably requested by the Loan
Originator to effect the repurchase of any such Loans or Residual Securities and
to have the Custodian return the Custodial Loan File of the deleted Loan to the
Servicer or to have the Trustee return the Loan Documents of the Deleted
Residual Security to the Servicer.

            (d) It is understood and agreed that the obligations of the Loan
Originator set forth in this Section 3.06 to cure, purchase or substitute for a
Unqualified Loan or Unqualified

3.02 hereof and in Exhibit E hereto and the Residual Security Transfer
Agreement. Any cause of action against the Loan Originator relating to or
arising out of a defect in a Custodial Loan File or the Loan Documents (with
respect to a Residual Security) or against the Loan Originator relating to or
arising out of a breach of any representations and warranties made in Sections
3.02 hereof and in Exhibit E hereto or the Residual Security Transfer Agreement
shall accrue as to any Loan or Residual Security upon (i) discovery of such
defect or breach by any party and notice thereof to the Loan Originator or
notice thereof by the Loan Originator to the Indenture Trustee, (ii) failure by
the Loan Originator to cure such defect or breach or purchase or substitute such
Loan or Residual Security as specified above, and (iii) demand upon the Loan
Originator, as applicable, by the Issuer or the Majority Noteholders for all
amounts payable in respect of such Loan or Residual Security.

            (e) Neither the Issuer nor the Indenture Trustee shall have any duty
to conduct any affirmative investigation other than as specifically set forth in
this Agreement as to the occurrence of any condition requiring the repurchase or
substitution of any Loan or Residual Security pursuant to this Section or the
eligibility of any Loan for purposes of this Agreement.

      Section 3.07 Dispositions.

            (a) The Majority Noteholders may at any time, and from time to time,
require that the Issuer redeem all or any portion of the Note Principal Balance
of the Notes by paying the Note Redemption Amount with respect to the Note
Principal Balance to be redeemed. In connection with any such redemption, the
Issuer shall effect Dispositions at the direction of the Majority Noteholders in
accordance with this Agreement, including in accordance with this Section 3.07.

            (b)   (i) In consideration of the consideration received from the
Depositor under the Loan Purchase and Contribution Agreement and the Residual
Securities Transfer Agreement, the Loan Originator hereby agrees and covenants
that in connection with each Disposition it shall effect the following:

                  (A) make such representations and warranties concerning the
Loans as of the "cut-off date" of the related Disposition to the Disposition
Participants as may be necessary to effect the Disposition and such additional
representations and warranties as may be necessary, in the reasonable opinion of
any of the Disposition Participants, to effect such Disposition; provided, that,
to the extent that the Loan Originator has at the time of the Disposition actual
knowledge of any facts or circumstances that would render any of such
representations and warranties materially false, the Loan Originator may notify
the Disposition Participants of such facts or circumstances and, in such event,
shall have no obligation to make such materially false representation and
warranty;

                  (B) supply such information, opinions of counsel, letters from
law and/or accounting firms and other documentation and certificates regarding
the origination of the Loans or the issuance of the Residual Securities as any
Disposition Participant shall reasonably request to effect a Disposition and
enter into such indemnification agreements customary for such

                                       50

<PAGE>

transaction relating to or in connection with the Disposition as the Disposition
Participants may reasonably require;

                  (C) make itself available for and engage in good faith
consultation with the Disposition Participants concerning information to be
contained in any document, agreement, private placement memorandum, or filing
with the Securities and Exchange Commission relating to the Loan Originator, the
Loans or the Residual Securities in connection with a Disposition and shall use
reasonable efforts to compile any information and prepare any reports and
certificates, into a form, whether written or electronic, suitable for inclusion
in such documentation;

                  (D) to implement the foregoing and to otherwise effect a
Disposition, enter into, or arrange for its Affiliates to enter into insurance
and indemnity agreements, underwriting or placement agreements, servicing
agreements, purchase agreements and any other documentation which may reasonably
be required of or reasonably deemed appropriate by the Disposition Participants
in order to effect a Disposition; and

                  (E) take such further actions as may be reasonably necessary
to effect the foregoing;

provided, that notwithstanding anything to the contrary, (a) the Loan Originator
shall have no liability for the Loans or the Residual Securities arising from or
relating to the ongoing ability of the related Borrowers to pay under the Loans
or under the loans underlying the Residual Securities; (b) none of the
indemnities hereunder shall constitute an unconditional guarantee by the Loan
Originator of collectibility of the Loans or the Residual Securities; (c) the
Loan Originator shall have no obligation with respect to the financial inability
of any Borrower to pay principal, interest or other amount owing by such
Borrower under a Loan or under a loan underlying a Residual Security; and (d)
the Loan Originator shall only be required to enter into documentation in
connection with Dispositions that is consistent with the prior public
securitizations of affiliates of the Loan Originator, provided that to the
extent an Affiliate of the Initial Noteholder acts as "depositor" or performs a
similar function in a Securitization, additional indemnities and informational
representations and warranties are provided which are consistent with those in
the Basic Documents and may upon request of the Loan Originator be set forth in
a separate agreement between an Affiliate of the Initial Noteholder and the Loan
Originator.

                  (ii) In the event of any Disposition to the Loan Originator or
any of its Affiliates (except in connection with a Securitization or a
Disposition to a QSPE Affiliate), the purchase price paid by the Loan Originator
or any such Affiliate shall be the "fair market value" of the Loans or the
Residual Securities subject to such Disposition (as determined by the Market
Value Agent based upon recent sales of comparable loans or securities or such
other objective criteria as may be approved for determining "fair market value"
by a "Big Five" national accounting firm).

                  (iii) As long as no Event of Default or Default shall have
occurred and be continuing under this Agreement or the Indenture, the Servicer
may continue to service the Loans included in any Disposition subject to any
applicable "term-to-term" servicing provisions in Section 9.01(c) and subject to
any required amendments to the related servicing provisions as

                                       51

<PAGE>

may be necessary to effect the related Disposition including but not limited to
the obligation to make recoverable principal and interest advances on the Loans.

            After the termination of the Revolving Period, the Loan Originator,
the Issuer and the Depositor shall use commercially reasonable efforts to effect
a Disposition at the direction of the Disposition Agent.

            (c) The Issuer shall effect Dispositions at the direction of the
Majority Noteholders in accordance with the terms of this Agreement and the
Basic Documents. In connection therewith, the Trust agrees to assist the Loan
Originator in such Dispositions and accordingly it shall, at the request and
direction of the Majority Noteholders:

                  (i) transfer, deliver and sell all or a portion of the Loans
or Residual Securities, as of the "cut-off dates" of the related Dispositions,
to such Disposition Participants as may be necessary to effect the Dispositions;
provided, that any such sale shall be for "fair market value," as determined by
the Market Value Agent in its reasonable discretion;

                  (ii) deposit the cash Disposition Proceeds into the
Distribution Account pursuant to Section 5.01(c)(2)(D);

                  (iii) to the extent that a Securitization creates any Retained
Securities, to accept such Retained Securities as a part of the Disposition
Proceeds in accordance with the terms of this Agreement; and

                  (iv) take such further actions, including executing and
delivering documents, certificates and agreements, as may be reasonably
necessary to effect such Dispositions.

            (d) The Servicer hereby covenants that it will take such actions as
may be reasonably necessary to effect Dispositions as the Disposition
Participants may request and direct, including without limitation providing the
Loan Originator such information as may be required to make representations and
warranties required hereunder, and covenants that it will make such
representations and warranties regarding its servicing of the Loans hereunder as
of the Cut-off Date of the related Disposition as reasonably required by the
Disposition Participants.

            (e) [reserved]

            (f) The Majority Noteholders may effect Whole Loan Sales upon
written notice to the Servicer of its intent to cause the Issuer to effect a
Whole Loan Sale at least 5 Business Days in advance thereof. The Disposition
Agent shall serve as agent for Whole Loan Sales and will receive a reasonable
fee for such services provided that no such fee shall be payable if (i) the Loan
Originator or its Affiliates purchase such Loans and (ii) no Event of Default or
Default shall have occurred. The Loan Originator or its Affiliates may
concurrently bid to purchase Loans in a Whole Loan Sale; provided, however, that
neither the Loan Originator nor any such Affiliates shall pay a price in excess
of the fair market value thereof (as determined by the Market Value Agent based
upon recent sales of comparable loans or such other objective criteria as may be
approved for determining "fair market value" by a "Big Five" national accounting
firm). In the event that the Loan Originator does not bid in any such Whole Loan

                                       52

<PAGE>

Sale, it shall have a right of first refusal to purchase the Loans offered for
sale at the price offered by the highest bidder. The Disposition Agent shall
conduct any Whole Loan Sale subject to the Loan Originator's right of first
refusal and shall promptly notify the Loan Originator of the amount of the
highest bid. The Loan Originator shall have five (5) Business Days following its
receipt of such notice to exercise its right of first refusal by notifying the
Disposition Agent in writing.

            (g) Except as otherwise expressly set forth under this Section 3.07,
the parties' rights and obligations under this Section 3.07 shall continue
notwithstanding the occurrence of an Event of Default.

            (h) The Disposition Participants (and the Majority Noteholders to
the extent directing the Disposition Participants) shall be independent
contractors to the Issuer and shall have no fiduciary obligations to the Issuer
or any of its Affiliates. In that connection, the Disposition Participants shall
not be liable for any error of judgment made in good faith and shall not be
liable with respect to any action they take or omits to take in good faith in
the performance of their duties.

      Section 3.08 Servicer Put; Servicer Call.

            (a) Servicer Put. The Servicer shall promptly purchase, upon the
written demand of the Majority Noteholders, any Put/Call Loan; provided,
however, that the Servicer may, upon receipt of such demand, elect to repurchase
such Put/Call Loan pursuant to (b) below, in which case such repurchase shall be
deemed a Servicer Call.

            (b) Servicer Call. The Servicer may repurchase any Put/Call Loan at
any time. Such Servicer Calls shall be solely at the option of the Servicer.
Prior to exercising a Servicer Call, the Servicer shall deliver written notice
to the Majority Noteholders and the Indenture Trustee which notice shall
identify each Loan to be purchased and the Repurchase Price therefor; provided,
however, that the Servicer may irrevocably waive its right to repurchase any
Put/Call Loan as soon as reasonably practicable following its receipt of notice
of the occurrence of any event or events giving rise to such Loan being a
Put/Call Loan.

            (c) In connection with each Servicer Put, the Servicer shall remit
for deposit into the Collection Account the Repurchase Price for the Loans to be
repurchased. In connection with each Servicer Call, the Servicer shall deposit
into the Collection Account the Repurchase Price for the Loans to be purchased.
The aggregate Repurchase Price of all Loans transferred pursuant to Section
3.08(a) shall in no event exceed the Unfunded Transfer Obligation at the time of
any Servicer Put.

      Section 3.09 Modification of Underwriting Guidelines.

      The Loan Originator shall give the Initial Noteholder prompt written
notification of any modification or change to the Underwriting Guidelines. If
the Noteholder objects in writing to any modification or change to the
Underwriting Guidelines within 15 days after receipt of such notice, no Loans
may be conveyed to the Issuer pursuant to this Agreement unless such Loans have
been originated pursuant to the Underwriting Guidelines without giving effect to
such modification or change. Notwithstanding anything contained in this
Agreement to the contrary,

                                       53
<PAGE>

any Loan conveyed to the Issuer pursuant to this Agreement pursuant to a
modification or change to the Underwriting Guidelines that has been rejected by
the Initial Noteholder or which the Initial Noteholder did not receive notice
of, such Loan shall be deemed an Unqualified Loan and be repurchased or
substituted for in accordance with Section 3.06.

Account, Wells Fargo Bank, N.A., as Indenture Trustee, for the benefit of the
Option One Owner Trust 2001-1B Mortgage-Backed Notes." If the Servicer makes

Shortfall to the Noteholders in respect of principal on the Notes.

            Notwithstanding that the Notes have been paid in full, the Indenture
Trustee, the Paying Agent and the Servicer shall continue to maintain the
Distribution Account hereunder until this Agreement has been terminated.

otherwise by check mailed to the address of such Noteholder appearing in the

defined in the Trust Agreement) on the date of distribution, without preference
or priority of any kind, and, except as otherwise provided in the next
succeeding sentence, shall be made by wire transfer of immediately available
funds to the account of each such holder, if such holder shall own of record a
Trust Certificate in an original denomination aggregating at least 25% of the
Percentage Interests and shall have so notified the Paying Agent and the
Indenture Trustee 5 Business Days prior to the related Record Date, and
otherwise by check mailed to the address of such Certificateholder appearing in
the Certificate Register. The final distribution on each Trust Certificate will
be made in like manner, but only upon presentment and surrender of such Trust
Certificate at the location specified in the notice to holders of the Trust
Certificates of such final distribution. Any amount distributed to the holders
of the Trust Certificates on any Payment Date shall not be subject to any claim
or interest of the Noteholders. In the event that at any time there shall be
more than one Certificateholder, the Indenture Trustee shall be entitled to
reasonable additional compensation from the Servicer for any increase in its
obligations hereunder.

      Section 5.03 Trust Accounts; Trust Account Property.

            (a) Control of Trust Accounts. Each of the Trust Accounts
established hereunder has been pledged by the issuer to the Indenture Trustee
under the Indenture and shall be subject to the lien of the Indenture. Amounts
distributed from each Trust Account in accordance with the terms of this
Agreement shall be released for the benefit of the Securityholders from the
Trust Estate upon such distribution thereunder or hereunder. The Indenture
Trustee shall possess all right, title and interest in and to all funds on
deposit from time to time in the Trust Accounts and in all proceeds thereof
(including all income thereon) and all such funds, investments, proceeds and
income shall be part of the Trust Account Property and the Trust Estate. If, at
any time, any Trust Account ceases to be an Eligible Account, the Indenture
Trustee shall, within ten Business Days (or such longer period, not to exceed 30
calendar days, with the prior written consent of the Majority Noteholders) (i)
establish a new Trust Account as an Eligible Account, (ii) terminate the
ineligible Trust Account, and (iii) transfer any cash and investments from such
ineligible Trust Account to such new Trust Account.

            With respect to the Trust Accounts, the Issuer and the Indenture
Trustee agree, that each such Trust Account shall be subject to the sole and
exclusive dominion, custody and control of the Indenture Trustee for the benefit
of the Noteholders, and, except as may be

                                       59
<PAGE>

consented to in writing by the Majority Noteholders, the Indenture Trustee shall
have sole signature and withdrawal authority with respect thereto.

            The Servicer (unless it is also the Paying Agent) shall not be
entitled to make any withdrawals or payments from the Trust Accounts.

            (b) (1) Investment of Funds. Funds held in the Collection Account,
the Distribution Account and the Transfer Obligation Account may be invested (to
the extent practicable and consistent with any requirements of the Code) in
Permitted Investments, as directed by the Servicer prior to the occurrence of an
Event of Default and by the Majority Noteholders thereafter, in writing or
facsimile transmission confirmed in writing by the Servicer or Majority
Noteholders, as applicable. In the event the Indenture Trustee has not received
such written direction, such Funds shall be invested in any Permitted Investment
described in clause (i) of the definition of Permitted Investments. In any case,
funds in the Collection Account, the Distribution Account and the Transfer
Obligation Account must be available for withdrawal without penalty, and any
Permitted Investments must mature or otherwise be available for withdrawal, one
Business Day prior to the next Payment Date and shall not be sold or disposed of
prior to its maturity subject to Subsection (b)(2) of this Section. All interest
and any other investment earnings on amounts or investments held in the
Collection Account, the Distribution Account and the Transfer Obligation Account
shall be paid to the Servicer immediately upon receipt by the Indenture Trustee.
All Permitted Investments in which funds in the Collection Account, the
Distribution Account or the Transfer Obligation Account are invested must be
held by or registered in the name of "Wells Fargo Bank, N.A., as Indenture
Trustee, in trust for the Option One Owner Trust 2001-1B Mortgage-Backed Notes."

                  (2) Insufficiency and Losses in Trust Accounts. If any amounts
are needed for disbursement from the Collection Account, the Distribution
Account or the Transfer Obligation Account held by or on behalf of the Indenture
Trustee and sufficient uninvested funds are not available to make such
disbursement, the Indenture Trustee shall cause to be sold or otherwise
converted to cash a sufficient amount of the investments in the Collection
Account, the Distribution Account or the Transfer Obligation Account, as the
case may be. The Indenture Trustee shall not be liable for any investment loss
or other charge resulting therefrom, unless such loss or charge is caused by the
failure of the Indenture Trustee to perform in accordance with written
directions provided pursuant to this Section 5.03.

            If any losses are realized in connection with any investment in the
Collection Account, the Distribution Account or the Transfer Obligation Account
pursuant to this Agreement during a period in which the Servicer has the right
to direct investments pursuant to Section 5.03(b), then the Servicer shall
deposit the amount of such losses (to the extent not offset by income from other
investments in the Collection Account, the Distribution Account or the Transfer
Obligation Account, as the case may be) into the Collection Account, the
Distribution Account or the Transfer Obligation Account, as the case may be,
immediately upon the realization of such loss. All interest and any other
investment earnings on amounts held in the Collection Account, the Distribution
Account and the Transfer Obligation Account shall be taxed to the Issuer and for
federal and state income tax purposes the Issuer shall be deemed to be the owner
of the Collection Account, the Distribution Account and/or the Transfer
Obligation Account, as the case may be.

                                       60
<PAGE>

            (c) Subject to Section 6.01 of the Indenture, the Indenture Trustee
shall not in any way be held liable by reason of any insufficiency in any Trust
Account held by the Indenture Trustee resulting from any investment loss on any
Permitted Investment included therein.

            (d) With respect to the Trust Account Property, the Indenture
Trustee acknowledges and agrees that:

                  (1) any Trust Account Property that is held in deposit
accounts shall be held solely in the Eligible Accounts, subject to the last
sentence of Subsection (a) of this Section 5.03; and each such Eligible Account
shall be subject to the sole and exclusive dominion, custody and control of the
Indenture Trustee; and, without limitation on the foregoing, the Indenture
Trustee shall have sole signature authority with respect thereto;

                  (2) any Trust Account Property that constitutes Physical
Property shall be delivered to the Indenture Trustee in accordance with
paragraphs (a) and (b) of the definition of "Delivery" in Section 1.01 hereof
and shall be held, pending maturity or disposition, solely by the Indenture
Trustee or a securities intermediary (as such term is defined in Section
8-102(a)(14) of the UCC) acting solely for the Indenture Trustee;

                  (3) any Trust Account Property that is a book-entry security
held through the Federal Reserve System pursuant to federal book-entry
regulations shall be delivered in accordance with paragraph (c) of the
definition of "Delivery" in Section 1.01 hereof and shall be maintained by the
Indenture Trustee, pending maturity or disposition, through continued book-entry
registration of such Trust Account Property as described in such paragraph; and

                  (4) any Trust Account Property that is an "uncertificated
security" under Article 8 of the UCC and that is not governed by clause (3)
above shall be delivered to the Indenture Trustee in accordance with paragraph
(d) of the definition of "Delivery" in Section 1.01 hereof and shall be
maintained by the Indenture Trustee, pending maturity or disposition, through
continued registration of the Indenture Trustee's (or its nominee's) ownership
of such security.

      Section 5.04 Advance Account.

            (a) The Servicer shall cause to be established and maintained in its
name, an Advance Account (the "Advance Account"), which need not be a segregated
account. The Advance Account shall be maintained with any financial institution
the Servicer elects.

            (b) Deposits and Withdrawals. Amounts in respect of the transfer of
Additional Note Principal Balances purchased on Transfer Dates related to Loans
and Residual Securities shall be deposited in and withdrawn from the Advance
Account as provided in Sections 2.01 (c) and 2.06 hereof and Section 3.01 of the
Note Purchase Agreement.

      Section 5.05 Transfer Obligation Account.

            (a) The Servicer, for the benefit of the Noteholders, shall cause to
be established and maintained in the name of the Indenture Trustee a Transfer
Obligation Account (the "Transfer Obligation Account"), which shall be a
separate Eligible Account and may be

                                       61

interest-bearing, entitled "Option One Owner Trust 2001-1B Transfer Obligation
Account, Wells Fargo Bank, N.A., as Indenture Trustee, in trust for the Option
One Owner Trust 2001-1B Mortgage-Backed Notes." The Indenture Trustee shall have
no monitoring or calculation obligation with respect to withdrawals from the
Transfer Obligation Account. Amounts in the Transfer Obligation Account shall be
invested in accordance with Section 5.03.

Transfer Obligation Account and deposit into the Distribution Account on such
Payment Date the lesser of (x) the amount then on deposit in the Transfer
Obligation Account and (y) the Interest Carry-Forward Amount as of such date.

            (f) If with respect to any Business Day there exists an
Overcollateralization Shortfall, the Paying Agent, upon the written direction of
the Initial Noteholder, shall withdraw from the Transfer Obligation Account and

such Overcollateralization Shortfall as of such date.

            (g) If with respect to any Payment Date there shall exist a Hedge
Funding Requirement, the Paying Agent, upon the written direction of the
Servicer or the Initial Noteholder, shall withdraw from the Transfer Obligation
Account and deposit into the Distribution Account on the Business Day prior to

Obligation Account (after making all other required withdrawals therefrom with
respect to such Payment Date) and (y) the amount of such Hedge Funding

            (i) The Paying Agent shall return to the Loan Originator all amounts
on deposit in the Transfer Obligation Account (after making all other
withdrawals pursuant to this Section 5.05) until the Majority Noteholders
provide written notice to the Indenture Trustee (with a copy to the Loan
Originator and the Servicer) of the occurrence of a default or event of default
(however defined) under any Basic Document with respect to the Issuer, the
Depositor, the Loan Originator or any of their Affiliates and (ii) upon the date
of the termination of this

<PAGE>

Agreement pursuant to Article X, the Paying Agent shall withdraw any remaining

      Section 5.06 Transfer Obligation.

            (a) In consideration of the transactions contemplated by the Basic
Documents, the Loan Originator agrees and covenants with the Depositor that:

                  (i) In connection with each Disposition it shall fund, or
cause to be funded, reserve funds, pay credit enhancer fees, pay, or cause to be
paid, underwriting fees, fund any difference between the cash Disposition
Proceeds and the aggregate Note Principal Balance at the time of such
Disposition, and make, or cause to be made, such other payments as may be, in
the reasonable opinion of the Disposition Agent, commercially reasonably
necessary to effect Dispositions, in each case to the extent that Disposition
Proceeds are insufficient to pay such amounts;

                  (ii) In connection with Hedging Instruments, on the Business
Day prior to each Payment Date, it shall deliver to the Servicer for deposit
into the Transfer Obligation Account any Hedge Funding Requirement (to the
extent amounts available on the related Payment Date pursuant to Section 5.01
are insufficient to make such payment), when, as and if due to any Hedging
Counterparty;

                  (iii) if any Interest Carry-Forward Amount shall occur, it
shall deposit into the Transfer Obligation Account any such Interest
Carry-Forward Amount on or before the Business Day preceding such related
Payment Date;

                  (iv) If on any Business Day there exists an
Overcollateralization Shortfall, upon the written direction of the Initial
Noteholder, it shall on such Business Day deposit into the Transfer Obligation
Account the full amount of the Overcollateralization Shortfall as of such date,
provided, that in the event that notice of such Overcollateralization Shortfall
is provided to the Loan Originator after 3:00 p.m. New York City time, the Loan
Originator shall make such deposit on the following Business Day; and

                  (v) Notwithstanding anything to the contrary herein, in the
event of the occurrence of an Event of Default under the Indenture, the Loan
Originator shall promptly deposit into the Transfer Obligation Account the
entire amount of the Unfunded Transfer Obligation;

provided, that notwithstanding anything to the contrary contained herein, the
Loan Originator's cumulative payments under or in respect of the Transfer
Obligations (after subtracting therefrom any amounts returned to the Loan
Originator pursuant to Section 5.05(i)(i)) together with the Servicer's payments
in respect of any Servicer Puts shall not in the aggregate exceed the Unfunded
Transfer Obligation.

            (b) The Loan Originator agrees that the Noteholders, as ultimate
assignee of the rights of the Depositor under this Agreement and the other Basic
Documents, may enforce the rights of the Depositor directly against the Loan
Originator.

      Section 6.03 Valuation of Loans and Residual Securities, Hedge Value and
Retained Securities Value; Market Value Agent.

            (a) The Initial Noteholder hereby irrevocably appoints, and the
Issuer hereby consents to the appointment of, the Market Value Agent as agent on
behalf of the Noteholders to determine the Market Value of each Loan and
Residual Security, the Hedge Value of each Hedging Instrument and the Retained
Securities Value of all Retained Securities.

            (b) Except as otherwise set forth in Section 3.07, the Market Value
Agent shall determine the Market Value of each Loan and Residual Security, for
the purposes of the Basic Documents, in its sole judgment, exercised in good
faith. In determining the Market Value of each Loan and Residual Security, the
Market Value Agent may consider any information that it may deem relevant and
shall base such determination primarily on the lesser of its estimate of the
projected proceeds from such Loan's or Residual Security's inclusion in (i) a
Securitization (inclusive of the projected Retained Securities Value of any
Retained Securities to be issued in connection with such Securitization) and
(ii) a Whole Loan Sale, in each case net of such Loan's ratable share of all
costs and fees associated with such Disposition, including, without limitation,
any costs of issuance, sale, underwriting and funding reserve accounts. The
Market Value Agent's determination, in its sole judgment, of Market Value shall
be conclusive and binding upon the parties hereto, absent manifest error
(including without limitation, any error contemplated in Section 2.08).

            (c) On each Business Day the Market Value Agent shall determine in
its sole judgment, exercised in good faith, the Hedge Value of each Hedging
Instrument as of such Business Day. In making such determination the Market
Value Agent may rely exclusively on quotations provided by the Hedging
Counterparty, by leading dealers in instruments similar to such Hedging
Instrument, which leading dealers may include the Market Value Agent and its
Affiliates and such other sources of information as the Market Value Agent may
deem appropriate.

            (d) On each Business Day, the Market Value Agent shall determine in
its sole judgment, exercised in good faith, the Retained Securities Value of the
Retained Securities, if any, expected to be issued pursuant to such
Securitization as of the closing date of such Securitization. In making such
determination the Market Value Agent may rely exclusively on quotations provided
by leading dealers in instruments similar to such Retained Securities, which
leading dealers may include the Market Value Agent and its Affiliates and such
other sources of information as the Market Value Agent may deem appropriate.

                          HEDGING; FINANCIAL COVENANTS

      Section 7.01 Hedging Instruments.

            (a) On each Transfer Date, the Trust shall enter into such Hedging
Instruments as the Market Value Agent, on behalf of the Majority Noteholders,
shall determine are necessary in order to hedge the interest rate risk with
respect to the Collateral Value of the

                                       67
<PAGE>

Loans being purchased on such Transfer Date. The Market Value Agent shall
determine, in its sole discretion, whether any Hedging Instrument conforms to
the requirements of Section 7.01(b), (c) and (d).

            (b) Each Hedging Instrument shall expressly provide that in the
event of a Disposition or other removal of the Loan from the Trust, such portion
of the Hedging Instrument shall terminate as the Disposition Agent deems
appropriate to facilitate the hedging of the risks specified in Section 7.01(a).
In the event that the Hedging Instrument is not otherwise terminated, it shall
contain provisions that allow the position of the Trust to be assumed by an
Affiliate of the Trust upon the liquidation of the Trust. The terms of the
assignment documentation and the credit quality of the successor to the Trust
shall be subject to the Hedging Counterparty's approval.

            (c) Any Hedging Instrument that provides for any payment obligation
on the part of the Issuer must (i) be without recourse to the assets of the
Issuer, (ii) contain a non-petition covenant provision in the form of Section
11.13, (iii) limit payment dates thereunder to Payment Dates and (iv) contain a
provision limiting any cash payments due on any day under such Hedging
Instrument solely to funds available therefor in the Collection Account on such
day pursuant to Section 5.01(c)(3)(ii) hereof and funds available therefor in
the Transfer Obligation Account.

            (d) Each Hedging Instrument must (i) provide for the direct payment
of any amounts thereunder to the Collection Account pursuant to Section
5.01(b)(1)(x), (ii) contain an assignment of all of the Issuer's rights (but
none of its obligations) under such Hedging Instrument to the Indenture Trustee
and shall include an express consent to the Hedging Counterparty to such
assignment, (iii) provide that in the event of the occurrence of an Event of
Default, such Hedging Instrument shall terminate upon the direction of the
Majority Noteholders, (iv) prohibit the Hedging Counterparty from "setting-off"
or "netting" other obligations of the Issuer or its Affiliates against such
Hedging Counterparty's payment obligations thereunder, (v) provide that the
appropriate portion of the Hedging Instrument will terminate upon the removal of
the related Loans from the Trust Estate and (vi) have economic terms that are
fixed and not subject to alteration after the date of assumption or execution.

            (e) If agreed to by the Majority Noteholders, the Issuer may pledge
its assets in order to secure its obligations in respect of Hedge Funding
Requirements, provided that such right shall be limited solely to Hedging
Instruments for which an Affiliate of the Initial Noteholder is a Hedging
Counterparty.

            (f) The aggregate notional amount of all Hedging Instruments shall
not exceed the Note Principal Balance as of the date on which each Hedging
Instrument is entered into by the Issuer and a Hedging Counterparty.

      Section 7.02 Financial Covenants.

      Each of the Loan Originator and the Servicer shall satisfy the Financial
Covenants.

                                  ARTICLE VIII

                                  THE SERVICER

      Section 8.01 Indemnification; Third Party Claims.

            (a) The Servicer shall indemnify the Loan Originator, the Owner
Trustee, the Trust, the Depositor, the Indenture Trustee and the Noteholders,
their respective officers, directors, employees, agents and "control persons,"
as such term is used under the Act and under the Securities Exchange Act of 1934
as amended (each a "Servicer Indemnified Party") and hold harmless each of them
against any and all claims, losses, damages, penalties, fines, forfeitures,
reasonable legal fees and related costs, judgments, and other costs and expenses
resulting from any claim, demand, defense or assertion based on or grounded
upon, or resulting from, a breach of any of the Servicer's representations and
warranties and covenants contained in this Agreement or in any way relating to
the failure of the Servicer to perform its duties and service the Loans in
compliance with the terms of this Agreement except to the extent such loss
arises out of such Servicer Indemnified Party's gross negligence or willful
misconduct; provided, however, that if the Servicer is not liable pursuant to
the provisions of Section 8.01(b) hereof for its failure to perform its duties
and service the Loans in compliance with the terms of this Agreement, then the
provisions of this Section 8.01 shall have no force and effect with respect to
such failure.

            (b) None of the Loan Originator, the Depositor or the Servicer or
any of their respective Affiliates, directors, officers, employees or agents
shall be under any liability to the Owner Trustee, the Issuer, the Indenture
Trustee or the Securityholders for any action taken, or for refraining from the
taking of any action, in good faith pursuant to this Agreement, or for errors in
judgment; provided, however, that this provision shall not protect the Loan
Originator, the Depositor, the Servicer or any of their respective Affiliates,
directors, officers, employees, agents against the remedies provided herein for
the breach of any warranties, representations or covenants made herein, or
against any expense or liability specifically required to be borne by such party
without right of reimbursement pursuant to the terms hereof, or against any
expense or liability which would otherwise be imposed by reason of misfeasance,
bad faith or negligence in the performance of the respective duties of the
Servicer, the Depositor or the Loan Originator, as the case may be. The Loan
Originator, the Depositor, the Servicer and any of their respective Affiliates,
directors, officers, employees, agents may rely in good faith on any document of
any kind which, prima facie, is properly executed and submitted by any Person
respecting any matters arising hereunder.

            (c) The Loan Originator agrees to indemnify and hold harmless the
Depositor and the Noteholders, as the ultimate assignees from the Depositor
(each an "Originator Indemnified Party," together with the Servicer Indemnified
Parties, the "Indemnified Parties"), from and against any loss, liability,
expense, damage, claim or injury arising out of or based on (i) any breach of
any representation, warranty or covenant of the Loan Originator, the Servicer or

                                       69
<PAGE>

their Affiliates, in any Basic Document, including, without limitation, the
origination or prior servicing of the Loans by reason of any acts, omissions, or
alleged acts or omissions arising out of activities of the Loan Originator, the
Servicer or their Affiliates, and (ii) any untrue statement by the Loan
Originator, the Servicer or its Affiliates of any material fact or any such
Person's failure to state a material fact necessary to make such statements not
misleading with respect to any such Person's statements contained in any Basic
Document, including, without limitation, any Officer's Certificate, statement,
report or other document or information prepared by any such Person and
furnished or to be furnished by it pursuant to or in connection with the
transactions contemplated thereby and not corrected prior to completion of the
relevant transaction including, without limitation, such written information as
may have been and may be furnished in connection with any due diligence
investigation with respect to the Loans or any such Person's business,
operations or financial condition, including reasonable attorneys' fees and
other costs or expenses incurred in connection with the defense of any actual or
threatened action, proceeding or claim; provided that the Loan Originator shall
not indemnify an Originator Indemnified Party to the extent such loss,
liability, expense, damage or injury is due to either an Originator Indemnified
Party's willful misfeasance, bad faith or negligence or by reason of an
Originator Indemnified Party's reckless disregard of its obligations hereunder;
provided, further, that the Loan Originator shall not be so required to
indemnify an Originator Indemnified Party or to otherwise be liable to an
Originator Indemnified Party for any losses in respect of the performance of the
Loans or Residual Securities, the creditworthiness of the Borrowers under the
Loans, changes in the market value of the Loans or Residual Securities or other
similar investment risks associated with the Loans or Residual Securities
arising from a breach of any representation or warranty set forth in Exhibit E
hereto or Section 3 of the Residual Securities Transfer Agreement, as
applicable, a remedy for the breach of which is provided in Section 3.06 hereof.
The provisions of this indemnity shall run directly to and be enforceable by an
Originator Indemnified Party subject to the limitations hereof.

            (d) With respect to a claim subject to indemnity hereunder made by
any Person against an Indemnified Party (a "Third Party Claim"), such
Indemnified Party shall notify the related indemnifying parties (each an
"Indemnifying Party") in writing of the Third Party Claim within a reasonable
time after receipt by such Indemnified Party of written notice of the Third
Party Claim unless the Indemnifying Parties shall have previously obtained
actual knowledge thereof. Thereafter, the Indemnified Party shall deliver to the
Indemnifying Parties, within a reasonable time after the Indemnified Party's
receipt thereof, copies of all notices and documents (including court papers)
received by the Indemnified Party relating to the Third Party Claim. No failure
to give such notice or deliver such documents shall effect the rights to
indemnity hereunder. Each Indemnifying Party shall promptly notify the Indenture
Trustee and the Indemnified Party (if other than the Indenture Trustee) of any
claim of which it has been notified and shall promptly notify the Indenture
Trustee and the Indemnified Party (if applicable) of its intended course of
action with respect to any claim.

            (e) If a Third Party Claim is made against an Indemnified Party,
while maintaining control over its own defense, the Indemnified Party shall
cooperate and consult fully with the Indemnifying Party in preparing such
defense, and the Indemnified Party may defend the same in such manner as it may
deem appropriate, including settling such claim or litigation after giving
notice to the Indemnifying Party of such terms and the Indemnifying Party will
promptly reimburse the Indemnified Party upon written request; provided,
however, that the

                                       70
<PAGE>

Indemnified Party may not settle any claim or litigation without the consent of
the Indemnifying Party; provided, further, that the Indemnifying Party shall
have the right to reject the selection of counsel by the Indemnified Party if
the Indemnifying Party reasonably determines that such counsel is inappropriate
in light of the nature of the claim or litigation and shall have the right to
assume the defense of such claim or litigation if the Indemnifying Party
determines that the manner of defense of such claim or litigation is
unreasonable.

      Section 8.02 Merger or Consolidation of the Servicer.

      The Servicer shall keep in full effect its existence, rights and
franchises as a corporation, and will obtain and preserve its qualification to
do business as a foreign corporation and maintain such other licenses and
permits in each jurisdiction necessary to protect the validity and
enforceability of each Basic Document to which it is a party and each of the
Loans and to perform its duties under each Basic Document to which it is a
party; provided, however, that the Servicer may merge or consolidate with any
other corporation upon the satisfaction of the conditions set forth in the
following paragraph.

      Any Person into which the Servicer may be merged or consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the
Servicer shall be a party, or any Person succeeding to the business of the
Servicer, shall be an Eligible Servicer and shall be the successor of the
Servicer, as applicable 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. The Servicer shall send notice of any such merger,
conversion, consolidation or succession to the Indenture Trustee and the issuer.

      Section 8.03 Limitation on Liability of the Servicer and Others.

      The Servicer and any director, officer, employee or agent of the Servicer
may rely on any document of any kind which it in good faith reasonably believes
to be genuine and to have been adopted or signed by the proper authorities
respecting any matters arising hereunder. Subject to the terms of Section 8.01
hereof, the Servicer shall have no obligation to appear with respect to,
prosecute or defend any legal action which is not incidental to the Servicer's
duty to service the Loans in accordance with this Agreement.

      Section 8.04 Servicer Not to Resign; Assignment.

      The Servicer shall not resign from the obligations and duties hereby
imposed on it except (a) with the consent of the Majority Noteholders or (b)
upon determination that its duties hereunder are no longer permissible under
applicable law. Any such determination pursuant to clause (b) of the preceding
sentence permitting the resignation of the Servicer shall be evidenced by an
Independent opinion of counsel to such effect delivered (at the expense of the
Servicer) to the Indenture Trustee and the Majority Noteholders. No resignation
of the Servicer shall become effective until a successor servicer, appointed
pursuant to the provisions of Section 9.02 hereof shall have assumed the
Servicer's responsibilities, duties, liabilities (other than those liabilities
arising prior to the appointment of such successor) and obligations under this
Agreement.

      Except as expressly provided herein, the Servicer shall not assign or
transfer any of its rights, benefits or privileges hereunder to any other
Person, or delegate to or subcontract with, or

                                       71
<PAGE>

authorize or appoint any other Person to perform any of the duties, covenants or
obligations to be performed by the Servicer hereunder and any agreement,
instrument or act purporting to effect any such assignment, transfer, delegation
or appointment shall be void.

      The Servicer agrees to cooperate with any successor Servicer in effecting
the transfer of the Servicer's servicing responsibilities and rights hereunder
pursuant to the first paragraph of this Section 8.04, including, without
limitation, the transfer to such successor of all relevant records and documents
(including any Loan Files in the possession of the Servicer) and all amounts
received with respect to the Loans and not otherwise permitted to be retained by
the Servicer pursuant to this Agreement. In addition, the Servicer, at its sole
cost and expense, shall prepare, execute and deliver any and all documents and
instruments to the successor Servicer including all Loan Files in its possession
and do or accomplish all other acts necessary or appropriate to effect such
termination and transfer of servicing responsibilities.

      Section 8.05 Relationship of Servicer to Issuer and the Indenture Trustee.

      The relationship of the Servicer (and of any successor to the Servicer as
servicer under this Agreement) to the Issuer, the Owner Trustee and the
Indenture Trustee under this Agreement is intended by the parties hereto to be
that of an independent contractor and not of a joint venturer, agent or partner
of the issuer, the Owner Trustee or the Indenture Trustee.

      Section 8.06 Servicer May Own Securities.

      Each of the Servicer and any Affiliate of the Servicer may in its
individual or any other capacity become the owner or pledgee of Securities with
the same rights as it would have if it were not the Servicer or an Affiliate
thereof except as otherwise specifically provided herein; provided, however,
that at any time that Option One or any of its Affiliates is the Servicer,
neither the Servicer nor any of its Affiliates (other than an Affiliate which is
a corporation whose purpose is limited to holding securities and related
activities and which cannot incur recourse debt) may be a Noteholder. Securities
so owned by or pledged to the Servicer or such Affiliate shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority, or distinction as among all of the Securities; provided,
however, that any Securities owned by the Servicer or any Affiliate thereof,
during the time such Securities are owned by them, shall be without voting
rights for any purpose set forth in this Agreement unless the Servicer or such
Affiliate owns all outstanding Securities of the related class. The Servicer
shall notify the Indenture Trustee promptly after it or any of its Affiliates
becomes the owner or pledgee of a Security.

      Section 8.07 Indemnification of the Indenture Trustee and Initial
Noteholder.

      The Servicer agrees to indemnify the Indenture Trustee and its employees,
officers, directors and agents, and reimburse its reasonable out-of-pocket
expenses in accordance with Section 6.07 of the Indenture as if it was a
signatory thereto. The Servicer agrees to indemnify the Initial Noteholder in
accordance with Section 9.01 of the Note Purchase Agreement as if it were
signatory thereto.

                           SERVICER EVENTS OF DEFAULT

      Section 9.01 Servicer Events of Default.

            (a) In case one or more of the following Servicer Events of Default
shall occur and be continuing, that is to say:

                  (1) any failure by Servicer to deposit into the Collection
Account or the Distribution Account or any failure by Servicer to make any of
the required payments therefrom; or

                  (2) any failure on the part of the Servicer duly to observe or
perform in any material respect any other of the material covenants or
agreements on the part of the Servicer, contained in any Basic Document to which
it is a party, which continues unremedied for a period of 30 days (or, in the
case of payment of insurance premiums, for a period of 15 days) after the date
on which written notice of such failure, requiring the same to be remedied,
shall have been given to the Servicer by any other party hereto or to the
Servicer (with copy to each other party hereto), by Holders of 25% of the
Percentage Interests of the Notes or the Trust Certificates; or

                  (3) any breach on the part of the Servicer of any
representation or warranty contained in any Basic Document to which it is a
party that materially and adversely affects the interests of any of the parties
hereto or any Securityholder and which continues unremedied for a period of 30
days after the date on which notice of such breach, requiring the same to be
remedied, shall have been given to the Servicer by any other party hereto or to
the Servicer (with copy to each other party hereto), by the Initial Noteholder
or Holders of 25% of the Percentage Interests (as defined in the Indenture) of
the Notes; or

                  (4) there shall have been commenced before a court or agency
or supervisory authority having jurisdiction in the premises an involuntary
proceeding against the Servicer under any present or future federal or state
bankruptcy, insolvency or similar law for the appointment of a conservator,
receiver, liquidator, trustee or similar official in any bankruptcy, insolvency,
readjustment of debt, marshaling of assets and liabilities or similar
proceedings, or for the winding-up or liquidation of its affairs, which action
shall not have been dismissed for a period of 60 days; or

                  (5) the Servicer shall consent to the appointment of a
conservator, receiver, liquidator, trustee or similar official in any
bankruptcy, insolvency, readjustment of debt, marshaling of assets and
liabilities or similar proceedings of or relating to it or of or relating to all
or substantially all of its property; or

                  (6) the Servicer shall admit in writing its inability to pay
its debts generally as they become due, file a petition to take advantage of any
applicable bankruptcy, insolvency or reorganization statute, make an assignment
for the benefit of its creditors, voluntarily suspend payment of its
obligations, or take any corporate action in furtherance of the foregoing; or

                                       73
<PAGE>

                  (7) Reserved; or

                  (8) the Servicer or the Loan Originator fails to comply with
any of its financial covenants set forth in Section 7.02; or

                  (9) a Change of Control of the Servicer; or

                  (10) so long as the Servicer or the Loan Originator is an
Affiliate of either of the Depositor or the Issuer and any "event of default' by
any such party occurs under any of the Basic Documents.

            (b) Then, and in each and every such case, so long as a Servicer
Event of Default shall not have been remedied, the Indenture Trustee or the
Majority Noteholders, by notice in writing to the Servicer may, in addition to
whatever rights such Person may have at law or in equity to damages, including
injunctive relief and specific performance, may terminate all the rights and
obligations of the Servicer under this Agreement and in and to the Loans and the
proceeds thereof, as servicer under this Agreement. Upon receipt by the Servicer
of such written notice, all authority and power of the Servicer under this
Agreement, whether with respect to the Loans or otherwise, shall, subject to
Section 9.02 hereof, pass to and be vested in a successor servicer, and the
successor servicer is hereby authorized and empowered to execute and deliver, on
behalf of the Servicer, as attorney-in-fact or otherwise, any and all documents
and other instruments and do or cause to be done all other acts or things
necessary or appropriate to effect the purposes of such notice of termination,
including, but not limited to, the transfer and endorsement or assignment of the
Loans and related documents. The Servicer agrees to cooperate with the successor
servicer in effecting the termination of the Servicer's responsibilities and
rights hereunder, including, without limitation, the transfer to the successor
servicer for administration by it of all amounts which shall at the time be
credited by the Servicer to each Collection Account or thereafter received with
respect to the Loans.

            (c) Upon the occurrence of (i) an Event of Default or Default under
any of the Basic Documents, (ii) a Servicer Event of Default under this
Agreement, (iii) a Rapid Amortization Trigger or (iv) a determination,
reasonably made by the Initial Noteholder, that an event has occurred that shall
materially impair the ability of the Servicer to service and administer the
Loans in accordance with the terms and provisions set forth in the Servicing
Addendum (each, a "Term Event"), the Servicer's right to service the Loans
pursuant to the terms of this Agreement shall be in effect for an initial period
commencing on the date on which such Term Event occurred and shall automatically
terminate at 5:00 p.m. (New York City time), on the last business day of the
calendar month in which such Term Event occurred (the "Initial Term").
Thereafter, the Initial Term shall be extendible in the sole discretion of the
Initial Noteholder by written notice (each, a "Servicer Extension Notice") of
the Initial Noteholder for successive one-month terms (each such term ending at
5:00 p.m. (New York City time), on the last business day of the related month).
Following a Term Event, the Servicer hereby agrees that the Servicer shall be
bound for the duration of the Initial Term and the term covered by any such
Servicer Extension Notice to act as the Servicer pursuant to this Agreement.
Following a Term Event, the Servicer agrees that if, as of 3:00 p.m. (New York
City time) on the last business day of any month, the Servicer shall not have
received a Servicer Extension Notice from the Initial Noteholder, the Servicer
shall give written notice of such non-receipt to the Initial Noteholder by

                                       74
<PAGE>

4:00 p.m. (New York City time). Following a Term Event, the failure of the
Initial Noteholder to deliver a Servicer Extension Notice by 5:00 p.m. (New York
City time) shall result in the automatic and immediate termination of the
Servicer (the "Termination Date"). Notwithstanding these time frames, the
Servicer and the Initial Noteholder shall comply with all applicable laws in
connection with such transfer and the Servicer shall continue to service the
Loans until completion of such transfer.

      Section 9.02 Appointment of Successor.

      On and after the date the Servicer receives a notice of termination
pursuant to Section 9.01 hereof or is automatically terminated pursuant to
Section 9.01 (c) hereof, or the Owner Trustee receives the resignation of the
Servicer evidenced by an Opinion of Counsel or accompanied by the consents
required by Section 8.04 hereof, or the Servicer is removed as servicer pursuant
to this Article IX or Section 4.01 of the Servicing Addendum, then, the Majority
Noteholders shall appoint a successor servicer to be the successor in all
respects to the 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
Servicer by the terms and provisions hereof; provided, however, that the
successor servicer shall not be liable for any actions of any servicer prior to
it.

      The successor servicer shall be obligated to make Servicing Advances
hereunder. As compensation therefor, the successor servicer appointed pursuant
to the following paragraph, shall be entitled to all funds relating to the Loans
which the Servicer would have been entitled to receive from the Collection
Account pursuant to Section 5.01 hereof as if the Servicer had continued to act
as servicer hereunder, together with other Servicing Compensation in the form of
assumption fees, late payment charges or otherwise as provided in Section 4.15
of the Servicing Addendum. The Servicer shall not be entitled to any termination
fee if it is terminated pursuant to Section 9.01 hereof but shall be entitled to
any accrued and unpaid Servicing Compensation to the date of termination.

      Any collections received by the Servicer after removal or resignation
shall be endorsed by it to the Indenture Trustee and remitted directly to the
successor servicer. The compensation of any successor servicer appointed shall
be the Servicing Fee, together with other Servicing Compensation provided for
herein. The Indenture Trustee, the Issuer, any Custodian, the Servicer and any
such successor servicer shall take such action, consistent with this Agreement,
as shall be reasonably necessary to effect any such succession. Any costs or
expenses incurred by the Indenture Trustee in connection with the termination of
the Servicer and the succession of a successor servicer shall be an expense of
the outgoing Servicer and, to the extent not paid thereby, an expense of such
successor servicer. The Servicer agrees to cooperate with the Indenture Trustee
and any successor servicer in effecting the termination of the Servicer's
servicing responsibilities and rights hereunder and shall promptly provide the
successor servicer all documents and records reasonably requested by it to
enable it to assume the Servicer's functions hereunder and shall promptly also
transfer to the successor servicer all amounts which then have been or should
have been deposited in any Trust Account maintained by the Servicer or which are
thereafter received with respect to the Loans. Upon the occurrence of an Event
of Default, the Majority Noteholders shall have the right to order the
Servicer's Loan Files and all other files of the Servicer relating to the Loans
and all other records of the Servicer and all

                                       75
<PAGE>

documents relating to the Loans which are then or may thereafter come into the
possession of the Servicer or any third parry acting for the Servicer to be
delivered to such custodian or servicer as it selects and the Servicer shall
deliver to such custodian or servicer such assignments as the Majority
Noteholders shall request. No successor servicer shall be held liable by reason
of any failure to make, or any delay in making, any distribution hereunder or
any portion thereof caused by (i) the failure of the Servicer to deliver, or any
delay in delivering, cash, documents or records to it or (ii) restrictions
imposed by any regulatory authority having jurisdiction over the Servicer
hereunder. No appointment of a successor to the Servicer hereunder shall be
effective until written notice of such proposed appointment shall have been
provided to the Initial Noteholder, the Indenture Trustee, the Issuer and the
Depositor, the Majority Noteholders and the Issuer shall have consented in
writing thereto.

      In connection with such appointment and assumption, the Majority
Noteholder may make such arrangements for the compensation of such successor
servicer out of payments on the Loans as they and such successor servicer shall
agree.

      Section 9.03 Waiver of Defaults.

      The Majority Noteholders may waive any events permitting removal of the
Servicer as servicer pursuant to this Article IX. Upon any waiver of a past
default, such default shall cease to exist and any Servicer Event of Default
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.

      Section 9.04 Accounting Upon Termination of Servicer.

      Upon termination of the Servicer under this Article IX, the Servicer
shall, at its own expense:

            (a) deliver to its successor or, if none shall yet have been
appointed, to the Indenture Trustee the funds in any Trust Account maintained by
the Servicer;

            (b) deliver to its successor or, if none shall yet have been
appointed, to the Custodian all Loan Files and related documents and statements
held by it hereunder and a Loan portfolio computer tape;

            (c) deliver to its successor or, if none shall yet have been
appointed, to the Indenture Trustee and to the Issuer and the Securityholders a
full accounting of all funds, including a statement showing the Monthly Payments
collected by it and a statement of monies held in trust by it for payments or
charges with respect to the Loans; and

            (d) execute and deliver such instruments and perform all acts
reasonably requested in order to effect the orderly and efficient transfer of
servicing of the Loans to its successor and to more fully and definitively vest
in such successor all rights, powers, duties, responsibilities, obligations and
liabilities of the Servicer under this Agreement.

            Section 10.01 Termination.

            (a) This Agreement shall terminate upon either: (A) the later of (i)
the satisfaction and discharge of the Indenture and the provisions thereof and
payment to the Noteholders of all amounts due and owing in accordance with the
provisions hereof or (ii) the disposition of all funds with respect to the last
Loan and Residual Security and the remittance of all funds due hereunder and the
payment of all amounts due and payable, including, in both cases, without
limitation, indemnification payments payable pursuant to any Basic Document to
the Indenture Trustee, the Owner Trustee, the Issuer, the Servicer and the
Custodian, written notice of the occurrence of either of which shall be provided
to the Indenture Trustee by the Servicer; or (B) the mutual consent of the
Servicer, the Depositor and all Securityholders in writing and delivered to the
Indenture Trustee by the Servicer.

            (b) The Securities shall be subject to an early redemption or
termination at the option of the Servicer and the Majority Noteholders in the
manner and subject to the provisions of Section 10.02 and 10.04 of this
Agreement.

            (c) Except as provided in this Article X, none of the Depositor, the
Servicer nor any Certificateholder or Noteholder shall be entitled to revoke or
terminate the Trust.

      Section 10.02 Optional Termination.

            (a) The Servicer may, at its option, effect an early termination of
the Trust on any Payment Date on or after the Clean-up Call Date. The Servicer
shall effect such early termination by providing notice thereof to the Indenture
Trustee and Owner Trustee and by purchasing all of the Loans, the Residual
Securities and the Advance Note at a purchase price, payable in cash, equal to
or greater than the Termination Price. The expense of any Independent appraiser
required in connection with the calculation and payment of the Termination Price
under this Section 10.02 shall be a nonreimbursable expense of the Servicer.

      Any such early termination by the Servicer shall be accomplished by
depositing into the Collection Account on the third Business Day prior to the
Payment Date on which the purchase is to occur the amount of the Termination
Price to be paid. The Termination Price and any amounts then on deposit in the
Collection Account (other than any amounts withdrawable pursuant to Section
5.01(c) (1) hereof) shall be deposited in the Distribution Account and
distributed by the Indenture Trustee pursuant to Section 5.01(c)(3) of this
Agreement and Section 9.1 of the Trust Agreement on the next succeeding Payment

the consent of any of the Securityholders, to cure any error or ambiguity, to
correct or supplement any provisions hereof which may be defective or
inconsistent with any other provisions hereof or to add any other provisions

interests of the Securityholders, as evidenced by an Opinion of Counsel to such
effect provided at the expense of the party requesting such Amendment.

Depositor, the Servicer, the Loan Originator, the Indenture Trustee and the
Issuer by written agreement, with the prior written consent of the Majority
Noteholders, for the purpose of adding any provisions to or changing in any

collections of payments on Loans or Residual Securities or distributions which
are required to be made on any Security, without the consent of the holders of
100% of the Securities, (ii) adversely affect in any material respect the

      Section 11.15 Due Diligence Fees, Due Diligence.

      The Loan Originator acknowledges that the Initial Noteholder has the right
to perform continuing due diligence reviews with respect to the Loans, for
purposes of verifying compliance with the representations, warranties and
specifications made hereunder, or otherwise, and the Loan Originator agrees that
upon reasonable prior notice (with no notice being required upon the occurrence
of an Event of Default) to the Loan Originator, the Initial Noteholder, the
Indenture Trustee and Custodian or its authorized representatives will be
permitted during normal business hours to examine, inspect, and make copies and
extracts of, the Loan Files and any and all documents, records, agreements,
instruments or information relating to such Loans in the possession or under the
control of the Servicer and the Indenture Trustee. The Loan Originator also
shall make available to the Initial Noteholder a knowledgeable financial or
accounting officer for the purpose of answering questions respecting the Loan
Files and the Loans and the financial condition of the Loan Originator. Without
limiting the generality of the foregoing, the Loan Originator acknowledges that
the Initial Noteholder may purchase Notes based solely upon the information
provided by the Loan Originator to the Initial Noteholder in the Loan Schedule
and the representations, warranties and covenants contained herein, and that the
Initial Noteholder, at its option, has the right at any time to conduct a
partial or complete due diligence review on some or all of the Loans securing
such purchase, including without limitation ordering new credit reports and new
appraisals on the related Mortgaged Properties and otherwise re-generating the
information used to originate such Loan. The Initial Noteholder may underwrite
such Loans itself or engage a mutually agreed upon third party underwriter to
perform such underwriting. The Loan Originator agrees to cooperate with the
Initial Noteholder and any third party underwriter in connection with such
underwriting, including, but not limited to, providing the Initial Noteholder
and any third party underwriter with access to any and all documents, records,
agreements, instruments or information relating to such Loans in the possession,
or under the control, of the Servicer. The Loan Originator further agrees that
the Loan Originator shall reimburse the Initial Noteholder for any and all
reasonable out-of-pocket costs and expenses incurred by the Initial Noteholder
in connection with the Initial Noteholder's activities pursuant to this Section
11.15 hereof (the "Due Diligence Fees"). In addition to the obligations set
forth in Section 11.17 of this Agreement, the Initial Noteholder agrees (on
behalf of itself and its Affiliates, directors, officers, employees and
representatives) to use reasonable precaution to keep confidential, in
accordance with its customary procedures for handling confidential information
and in accordance with safe and sound practices, and not to disclose to any
third party, any non-public information supplied to it or otherwise obtained by
it hereunder with respect to the Loan Originator or any of its Affiliates
(including, but not limited to, the Loan

                                       82
<PAGE>

File); provided, however, that nothing herein shall prohibit the disclosure of
any such information to the extent required by statute, rule, regulation or
judicial process; provided, further that, unless specifically prohibited by
applicable law or court order, the Initial Noteholder shall, prior to disclosure
thereof, notify the Loan Originator of any request for disclosure of any such
non-public information. The Initial Noteholder further agrees not to use any
such non-public information for any purpose unrelated to this Agreement and that
the Initial Noteholder shall not disclose such non-public information to any
third party underwriter in connection with a potential Disposition without
obtaining a written agreement from such third party underwriter to comply with
the confidentiality provisions of this Section 11.15.

      Section 11.16 No Reliance.

      Each of the Loan Originator, the Depositor and the Issuer hereby
acknowledges that it has not relied on the Initial Noteholder or any of its
officers, directors, employees, agents and "control persons" as such term is
used under the Act and under the Securities Exchange Act of 1934, as amended,
for any tax, accounting, legal or other professional advice in connection with
the transactions contemplated by the Basic Documents, that each of the Loan
Originator, the Depositor and the Issuer has retained and been advised by such
tax, accounting, legal and other professionals as it has deemed necessary in
connection with the transactions contemplated by the Basic Documents and that
the Initial Noteholder makes no representation or warranty, and shall have no
liability with respect to, the tax, accounting or legal treatment or
implications relating to the transactions contemplated by the Basic Documents.

      Section 11.17 Confidential Information.

      In addition to the confidentiality requirements set forth in Section 11.15
of the Agreement, each Noteholder, as well as the Indenture Trustee and the
Disposition Agent (each of said parties singularly referred to herein as a
"Receiving Party" and collectively referred to herein as the "Receiving
Parties"), agrees to hold and treat all Confidential Information (as defined
below) in confidence and in accordance with this Section. Such Confidential
Information will not, without the prior written consent of the Servicer and the
Loan Originator, be disclosed or used by such Receiving Parties or its
subsidiaries, Affiliates, directors, officers, members, employees, agents or
controlling persons (collectively, the "Information Recipients") other than for
the purpose of making a decision to purchase or sell Notes or taking any other
permitted action under this Agreement and or any other Basic Document. Each
Receiving Party agrees to disclose Confidential Information only to its
Information Recipients who need to know it for the purpose of making a decision
to purchase or sell Notes or the taking of any other permitted action under this
Agreement and or any other Basic Document (including in connection with the
servicing of the Loans and in connection with any servicing transfers) and who
are informed by such Receiving Party of its confidential nature and who agree to
be bound by the terms of this Section 11.17. Disclosure that is not in violation
of the Right to Financial Privacy Act, the Gramm-Leach-Bliley Act or other
applicable law by such Receiving Party of any Confidential Information at the
request of its outside auditors or governmental regulatory authorities in
connection with an examination of a Receiving Party by any such authority shall
not constitute a breach of its obligations under this Section 11.17 and shall
not require the prior consent of the Servicer and the Loan Originator.

                                       83
<PAGE>

      Each Receiving Party shall be responsible for any breach of this Section
11.17 by its Information Recipients. The Initial Noteholder may use Confidential
Information for internal due diligence purposes in connection with its analysis
of the transactions contemplated by the Basic Documents. The Disposition Agent
may disclose Confidential Information to the Disposition Participants as
required to effect Dispositions. This Section 11.17 shall terminate upon the
occurrence of an Event of Default; provided, however, that such termination
shall not relieve the Receiving Parties or their respective Information
Recipients from the obligation to comply with the Gramm-Leach-Bliley Act or
other applicable law with respect to their use or disclosure of Confidential
Information following the occurrence of an Event of Default.

      As used herein, "Confidential Information" means non-public personal
information (as defined in the Gramm-Leach-Bliley Act and its enabling
regulations issued by the Federal Trade Commission) regarding Borrowers.
Confidential Information shall not include information which (i) is or becomes
generally available to the public other than as a result of a disclosure by a
Receiving Party or any Information Recipients; (ii) was available to a Receiving
Party on a non-confidential basis prior to its disclosure to Receiving Party by
the Servicer or the Loan Originator; (iii) is required to be disclosed by a
governmental authority or related governmental agencies or as otherwise required
by law; (iv) becomes available to a Receiving Party on a non-confidential basis
from a Person other than the Servicer or the Loan Originator who, to the best
knowledge of such Receiving Party, is not otherwise bound by a confidentiality
agreement with the Servicer or the Loan Originator and is not otherwise
prohibited from transmitting the information to such Receiving Party.

      Section 11.18 Conflicts.

      Notwithstanding anything contained in the Basic Documents to the contrary,
in the event of the conflict between the terms of this Agreement and any other
Basic Document, the terms of this Agreement shall control.

      Section 11.19 Limitation on Liability.

      It is expressly understood and agreed by the parties hereto that (a) this
Agreement is executed and delivered by Wilmington Trust Company, not
individually or personally, but solely as Owner Trustee of Option One Owner
Trust 2001-1B, in the exercise of the powers and authority conferred and vested
in it, (b) each of the representations, undertakings and agreements herein made
on the part of the Issuer is made and intended not as personal representations,
undertakings and agreements by Wilmington Trust Company but is made and intended
for the purpose for binding only the Issuer, (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 hereto
and by any Person claiming by, through or under the parties hereto and (d) under
no circumstances shall Wilmington Trust Company be personally liable for the
payment of any indebtedness or expenses of the Issuer or be liable for the
breach or failure of any obligation, representation, warranty or covenant made
or undertaken by the Issuer under this Agreement or any other related documents.

      Section 11.20 No Agency.

      Nothing contained herein or in the Basic Documents shall be construed to
create an agency or fiduciary relationship between the Initial Noteholder or the
Majority Noteholders or any of their Affiliates and the Issuer, the Depositor,
the Loan Originator or the Servicer. None of the Initial Noteholder, the
Majority Noteholders or any of their Affiliates shall be liable for any acts or
actions affected in connection with a disposition of Loans or Residual
Securities, including without limitation, any Securitization pursuant to Section
3.06, any Loan Originator Put or Servicer Call pursuant to Section 3.07 hereof
nor any Whole Loan Sale pursuant to Section 3.10 hereof.
