          (b) As of the Closing Date and as of each Transfer Date, the Issuer
acknowledges (or will acknowledge pursuant to the S&SA Assignment) the
conveyance to it of the Trust Estate, including all rights, title and interest
of the Depositor and any QSPE Affiliate in and to the Trust Estate, receipt of
which is hereby acknowledged by the Issuer. Concurrently with such delivery, as
of the Closing Date and as of each Transfer Date, pursuant to the Indenture the
Issuer pledges and grants a continuing first priority security interest in the
Trust Estate to the Indenture Trustee. In addition, concurrently with such
delivery and in exchange therefor, the Owner Trustee, pursuant to the
instructions of the Depositor, has executed (not in its individual capacity, but
solely as Owner Trustee on behalf of the Issuer) and caused the Trust
Certificates to be authenticated and delivered to or at the direction of the
Depositor.

          (c) (i) Pursuant to and subject to the Note Purchase Agreement, the
Trust may, at its sole option, from time to time request that the Note Agent
advance on any Transfer Date Additional Note Principal Balances and the Note
Agent shall remit on such Transfer Date, to the Advance Account, an amount equal
to the Additional Note Principal Balance.

               (ii) Notwithstanding anything to the contrary herein, in no event
shall the Note Agent be required to advance Additional Note Principal Balances
on a Transfer Date if the conditions precedent to a transfer of the Loans under
Section 2.06 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.

               (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


                                       27

<PAGE>

Note Principal Balance held by such Noteholder. The Note Agent 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 Note Agent'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
related Servicer's Loan File and Custodial Loan File shall be vested in the
Trust for the benefit of the Securityholders, although possession of the
Servicer's Loan File on behalf of and for the benefit of the Securityholders
shall remain with the Servicer, and the Custodian shall take possession of the
Custodial Loan Files as contemplated in Section 2.05 hereof.

     Section 2.03 Books and Records; Intention of the Parties.

          (a) As of each Transfer Date, the sale of each of the Loans 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 which shall be clearly marked to
reflect the ownership of each Loan, 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 (as to which no
treatment is herein contemplated), 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 Trust Estate including, without limitation, the Loans and all other
property comprising the Trust Estate specified in Section 2.01 (a) hereof, from
the Depositor to the Issuer and such property shall not be property of the
Depositor. 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 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 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


                                       28

<PAGE>

and that, in such event, with respect to such property, (i) consisting of Loans
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 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 a UCC1 Financing Statement naming the Issuer as
"secured party" and describing the Trust Estate being sold by the Depositor to
the Issuer with the office of the Secretary of State of the state in which the
Depositor is located (pursuant to Section 9-307 of the UCC) 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 a UCC1 Financing Statement naming the Depositor as
"secured party" and describing the Loans being sold by the Loan Originator to
the Depositor with the office of the Secretary of the State in which the Loan
Originator is located (pursuant to Section 9-307 of the UCC) 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 (or,
in the case of each Wet Funded Loan, the related Wet Funded Custodial File
Delivery Date), in accordance with the terms and conditions set forth in the
Custodial Agreement, deliver or cause to be delivered to the Custodian, as the
designated agent of the Indenture Trustee, a Loan Schedule and each of the
documents constituting the Custodial Loan File with respect to each Loan. The
Loan Originator shall assure that (i) in the event that any Wet Funded Loan is
not closed and funded to the order of the appropriate Borrower on the day funds
are provided to the Loan Originator by the Note Agent on behalf of the Issuer,
such funds shall be promptly returned to the Note Agent 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 Note Agent on behalf of the Issuer.

          (b) The Loan Originator shall, on the related Transfer Date (or in the
case of a Wet Funded Loan, on or before the related Wet Funded Custodial 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
of California (or upon prior written notice from the Custodian to the Loan
Originator and the Note Agent and delivery of an Opinion of Counsel with respect
to the continued perfection of the Indenture Trustee's


                                       29

security interest, in the State of Minnesota or Utah) and, in connection
therewith, shall act solely as agent for the Noteholders in accordance with the
terms hereof and not as agent for the Loan Originator, the Servicer or any other
party.

     Section 2.05 Acceptance by the Indenture Trustee of the Loans; Certain
Substitutions and Repurchases; Certification by the Custodian.

          (a) The Indenture Trustee declares that it will cause the Custodian 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 Note Agent at the Repurchase Price
thereof with respect to such Loan by depositing such Repurchase Price in the
Collection Account. In lieu of such a repurchase, the Depositor and Loan
Originator may comply with the substitution provisions of Section 3.06 hereof.
The Loan Originator shall provide the Servicer, the Indenture Trustee, the
Issuer and the Note Agent with a certification of a Responsible Officer on or
prior to such repurchase or substitution indicating that the Loan Originator
intends to repurchase or substitute such Loan.

               (iii) It is understood and agreed that the obligation of the Loan
Originator to repurchase or substitute any such Loan pursuant to this Section
2.05(b) shall constitute the sole remedy with respect to such failure to 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 any document
is valid and binding, whether the text of any assignment or endorsement is in
proper or recordable form, whether any document has been recorded in accordance
with the requirements of any applicable jurisdiction, or whether a blanket
assignment is permitted in any applicable jurisdiction.

          (d) The Servicer's Loan File shall be held in the custody of the
Servicer (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. It is intended that, by
the Servicer's agreement pursuant to this Section 2.05(d), the Indenture Trustee
shall be deemed to have possession of the Servicer's Loan Files for purposes of
Section 9-313 of the Uniform Commercial Code of the state in which such
documents or instruments are located. The Servicer shall promptly report to the
Indenture Trustee any failure 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. Subject to Section 8.01(d), the Servicer agrees to
indemnify the Securityholders and the Indenture Trustee, their 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 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.

compliance with the terms of each Basic Document to which the Depositor is a
party will not constitute a violation with respect to, any order or decree of

Depositor or any of its properties or materially and adversely affect the

Depositor is, to the knowledge of the Depositor, threatened or otherwise pending

Securities;

delivery of each Basic Document to which it is a party by the Loan Originator
and its performance and compliance with the terms of each Basic Document to

materially and adversely affect the sale of the Loans to the Depositor, the
performance by the Loan Originator of its obligations under, or the validity or
enforceability of, any Basic Document to which it is a party or the Securities;

          (f) No consent, approval, authorization or order of any court or

state any material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading. All written
information furnished after the date hereof by or on behalf of the Loan
Originator to the Note Agent in connection with the Basic Documents to which it

certified.

          (i) The Loan Originator is solvent, is able to pay its debts as they

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
Originator, the Depositor, the Servicer, the Indenture Trustee, the Note Agent
or the Trust of a breach of any of the foregoing representations and warranties
that materially and adversely affects the value of any Loan or the interests of
the Securityholders in any Loan or in the Securities, the party discovering such

hereunder to the Securityholders, the Depositor, the Servicer, the Indenture
Trustee or the Trust respecting a breach of the representations and warranties
contained in this Section 3.02. The fact that the Note Agent has conducted or
has failed to conduct any partial or complete due diligence investigation of the

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 other

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

adversely affect the condition (financial or otherwise) or operations of the
Servicer or materially and adversely affect the performance of its duties under
any Basic Document to which it is a party;

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 or otherwise pending
before any court, administrative agency or other tribunal that (A) has a
reasonable probability of being determined adversely to the Servicer, and if so
determined, would prohibit its entering into any Basic Document to which it is a
party, (B) seek to prevent the consummation of any of the transactions
contemplated by any Basic Document to which it is a party or (C) if determined
adversely to the Servicer, would have a reasonable probability of resulting in
damages or other remedies that would 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;

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

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 Note Agent
in connection with the negotiation, preparation or delivery of the Basic
Documents to which it is a party or delivered pursuant thereto, when taken as a
whole, do not contain any untrue statement of material fact or omit to state any
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. All written
information furnished after the date hereof by or on behalf of the Servicer to
the Note Agent in connection with the Basic Documents to which it is a party and

set forth in Section 7.02; and

          (k) The Servicer is an Eligible Servicer and covenants to remain an

<PAGE>

Payments and (2) transfer those Monthly Payments which relate to Loans owned by
the Trust from the Lock-Box Clearing Custodial Account to the Collection Account
within two Business Days of the Servicer's receipt of such Monthly Payments.

     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

     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, 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 Note Agent 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 shall survive the conveyance of the
Loans 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,
the Note Agent 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 and adversely affects the value or
enforceability of any Loan or the interests of the Securityholders in any Loan
(notwithstanding that such representation and warranty was made to the Loan
Originator's best knowledge) or which constitutes a breach of the
representations and


                                       41

<PAGE>

warranties set forth in Exhibit E, 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"), the Loan
Originator shall promptly upon receipt of written instructions from the Majority
Noteholders either (i) remove such Unqualified Loan from the Trust (in which
case it shall become a Deleted Loan) and substitute one or more Qualified
Substitute Loans in the manner and subject to the conditions set forth in this
Section 3.06 or (ii) purchase such Unqualified Loan at a purchase price equal to
the Repurchase Price with respect to such Unqualified Loan by depositing or
causing to be deposited such Repurchase Price in the Collection Account.

     Any substitution of Loans 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) hereof.

          (b) 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 Indenture Trustee and Note Agent 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.

     The Servicer shall deposit in the Collection Account all payments received
in connection with each Qualified Substitute Loan after the date of such
substitution. Monthly Payments received with respect to Qualified Substitute
Loans 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 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. 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 Note Agent that such substitution has taken place and the Servicer
shall amend the Loan Schedule to reflect (i) the removal of such Deleted Loan
from the terms of this Agreement and (ii) the substitution of the Qualified
Substitute Loan. The Servicer shall promptly deliver to the Issuer, the Loan
Originator, the Indenture Trustee and Note Agent, a copy of the amended Loan
Schedule. Upon such substitution, such Qualified Substitute Loan or Loans 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


                                       42

<PAGE>

Exhibit E hereto. 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 from the lien of the Indenture and
the Servicer will cause such Qualified Substitute Loan to be pledged to the
Indenture Trustee under the Indenture as part of the Trust Estate.

          (c) With respect to all Unqualified Loans or other Loans repurchased
by the Loan Originator pursuant to this Agreement, upon the deposit of the
Repurchase Price therefor into the Collection Account or the conveyance of one
or more Qualified Substitute Loans and payment of any Substitution Adjustment,
(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, 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, 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 and to have the Custodian return the Custodial Loan File of the
deleted Loan 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
Unqualified Loans constitute the sole remedies hereunder of the Depositor, the
Issuer, the Indenture Trustee, the Note Agent, the Owner Trustee and the
Securityholders respecting a breach of the representations and warranties
contained in Sections 3.02 hereof and in Exhibit E hereto. Any cause of action
against the Loan Originator relating to or arising out of a defect in a
Custodial Loan File 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 shall accrue as to any Loan 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 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.

          (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 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


                                       43

<PAGE>

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, 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 as any Disposition Participant shall reasonably
request to effect a Disposition and enter into such indemnification agreements
customary for such 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 or
the Loans 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 arising from or relating to the ongoing
ability of the related Borrowers to pay under the Loans; (b) none of the
indemnities hereunder shall constitute an unconditional guarantee by the Loan
Originator of collectibility of the Loans; (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; and (d)
the Loan Originator shall only be required to enter into documentation in
connection with Dispositions that is consistent


                                       44

<PAGE>

with the prior public securitizations of affiliates of the Loan Originator,
provided that to the extent an Affiliate of the Note Agent 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 Note Agent 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 subject to
such Disposition (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).

               (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 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, 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


                                       45

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 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;


                                       46

<PAGE>

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 Note Agent 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, 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 Note Agent or which the Note Agent 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.

appropriate Person paying such amounts, as the case may be, to remit directly to
the Servicer for deposit into the Collection Account all amounts referenced in
clauses (i) through (ix) to the extent such amounts are in excess of a Monthly

amounts, it will deposit them into the Collection Account on the same Business

deemed distributed pursuant to the terms of Section 5.01(c). Upon notice of an
additional Payment Date to the Paying Agent and the Indenture Trustee as

          (d) [Reserved]

     Section 5.02 Payments to Securityholders.

          (a) All distributions made on the Notes on each Payment Date or
pursuant to Section 5.04(b) of the Indenture will be made on a pro rata basis
among the Noteholders of record of the Notes on the next preceding Record Date
based on the Percentage Interest represented by their respective Notes, 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 such Noteholder, if such Noteholder shall own
of record Notes having a Percentage Interest (as defined in the Indenture) of at
least 20% 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 Noteholder appearing in the Notes Register. The final
distribution on each Note will be made in like manner, but only upon presentment
and surrender of such Note at the location specified in the notice to
Noteholders of such final distribution.

          (b) All distributions made on the Trust Certificates on each Payment

with the Percentage Interest among the holders of the Trust Certificates of
record on the next preceding Record Date based on their Percentage Interests (as
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

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


                                       52

<PAGE>

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 "control"
(in accordance with Section 9-104 of the UCC) of the Indenture Trustee for the
benefit of the Noteholders, and, except as may be consented to in writing by the
Majority Noteholders or provided in the related Blocked Account Agreement, 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, National Association, as
Indenture Trustee, in trust for the Option One Owner Trust 2003-4
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


                                       53

<PAGE>

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.

          (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 "control" (in accordance with Section 9-104 of the UCC) of the
Indenture Trustee as provided in the related Blocked Account Agreement; and,
without limitation on the foregoing, the Indenture Trustee shall have sole
signature authority with respect thereto except to the extent otherwise provided
in the related Blocked Account Agreement;

               (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

respect of any Servicer Puts shall not in the aggregate exceed the Unfunded
Transfer Obligation.

     Section 6.03 Valuation of Loans, Hedge Value and Retained Securities Value;

               Market Value Agent.

          (a) The Note Agent 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, 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, for the purposes of the
Basic Documents, in its sole judgment. In determining the Market Value of each
Loan, 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 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 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 the Retained Securities Value of the Retained Securities, if
any, expected to be issued


                                       60

<PAGE>

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.

     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 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)(viii), (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.


                                       61

          (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 Note Agent 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.

          (a) Each of the Loan Originator and the Servicer shall maintain a

ratio of 1.0 or greater at any time pursuant to the Capital Adequacy Test,

non-recourse debt) less (B) 91% of its mortgage loan inventory held for sale
less (C) 90% of servicing advance receivables (determined and valued in
accordance with GAAP) to (ii) Tangible Net Worth) of 0.50x at any time.

          (d) Each of the Loan Originator and the Servicer shall maintain a
minimum liquidity facility (defined as a committed, unsecured, non-amortizing
liquidity facility from H&R Block, Inc. not to mature (scheduled or accelerated)
prior to the Maturity Date) in an amount no less than $150 million. Such
facility from H&R Block, Inc. cannot contain covenants or termination events
more restrictive than the covenants or termination events contained in the Basic
Documents.

          (e) Each of the Loan Originator and the Servicer shall maintain a
minimum "Net Income" (defined and determined in accordance with GAAP) of at
least $1 based on the total of the current quarter combined with the previous
three quarters.

          (f) Each of the Loan Originator and the Servicer shall maintain a
committed warehouse credit facility, with a maturity date (scheduled or
accelerated) not earlier than the Maturity Date, in an amount not less than the
Maximum Note Principal Balance from a third-party entity that is not an
Affiliate of the Note Agent, the Loan Originator or the Servicer.

                                  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


                                       62

<PAGE>

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. In addition to the foregoing, the
Servicer shall indemnify the Note Agent and hold it harmless against any amounts
the Notes Agent is obligated to pay pursuant to any Blocked Account Agreement to
the financial institution at which either of the Trust Accounts is maintained to
the extent such amounts are incurred or relate to a period following the
delivery of a Termination Notice (as defined under such Blocked Account
Agreement) under such Blocked Account Agreement.

          (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
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


                                       63

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, the creditworthiness of the Borrowers under the Loans, changes in the
market value of the Loans or other similar investment risks associated with the
Loans arising from a breach of any representation or warranty set forth in
Exhibit E hereto, 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 Indemnified Party may not settle any claim or litigation without the consent
of the Indemnifying Party.

     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


                                       64

<PAGE>

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 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


                                       65

<PAGE>

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 Note Agent.

     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 Note Agent in accordance
with Section 9.01 of the Note Purchase Agreement as if it were signatory
thereto.

                                   ARTICLE IX
                           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 (and shall not have been waived by the majority
Noteholders pursuant to Section 9.03), that is to say:

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


                                       66

<PAGE>

               (2) any failure on the part of the Servicer duly to observe or
perform in any material respect any other 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 in any material
respect of any representation or warranty contained in any Basic Document to
which it is a party 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 Note Agent 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

               (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


                                       67

<PAGE>

or in equity to damages, including injunctive relief and specific performance,
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) an event that has a
reasonable possibility of materially impairing the ability of the Servicer to
service and administer the Loans in accordance with the terms and provision set
forth in the Basic Documents (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 Note Agent by written notice (each, a "Servicer Extension
Notice") of the Note Agent 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 Note Agent, the Servicer
shall give written notice of such non-receipt to the Note Agent by 4:00 p.m.
(New York City time). Following a Term Event, the failure of the Note Agent 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
Note Agent 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


                                       68

<PAGE>

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 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 Note Agent, 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.

                             TERMINATION; PUT OPTION

     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, 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
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.


                                       70

          (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, the Note Agent and Owner Trustee and by purchasing all of the Loans 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
Date; and any amounts received with respect to the Loans and Foreclosure
Properties subsequent to the final Payment Date shall belong to the purchaser
thereof.

     Section 10.03 Notice of Termination.

     Notice of termination of this Agreement or of early redemption and
termination of the Issuer pursuant to Section 10.01 shall be sent by the
Indenture Trustee to the Noteholders in accordance with Section 10.02 of the
Indenture.

     Section 10.04 Put Option.

     The Majority Noteholders may, at their option, effect a put of the entire
outstanding Note Principal Balance, or any portion thereof, to the Trust on any
date by exercise of the Put Option. The Majority Noteholders shall effect such
put by providing notice thereof in accordance with Section 10.05 of the
Indenture.

     Unless otherwise agreed by the Majority Noteholders, on the third Business
Day prior to the Put Date, the Issuer shall deposit the Note Redemption Amount
into the Distribution Account and, if the Put Date occurs after the termination
of the Revolving Period and constitutes a put of the entire outstanding Note
Principal Balance, 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 Paying Agent
pursuant to section 5.01 (c) (3) of this Agreement on the Put Date; and any
amounts received with respect to the Loans and Foreclosure Properties subsequent
to the Put Date shall belong to the Issuer.

                            MISCELLANEOUS PROVISIONS

     Section 11.01 Acts of Securityholders.

     Except as otherwise specifically provided herein and except with respect to
Section 11.02(b), whenever action, consent or approval of the Securityholders is
required under this Agreement, such action, consent or approval shall be deemed
to have been taken or given on behalf of, and shall be binding upon, all
Securityholders if the Majority Noteholders agree to take such action or give
such consent or approval.

     Section 11.02 Amendment.

          (a) This Agreement may be amended from time to time by the Depositor,
the Servicer, the Loan Originator, the Indenture Trustee and the Issuer by
written agreement with notice thereof to the Securityholders, without 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
with respect to matters or questions arising under this Agreement; provided,
however, that such action will not adversely affect in any material respect the
interests of the Securityholders, as evidenced by an Opinion of Counsel to such
effect provided at the expense of the party requesting such Amendment.

          (b) This Agreement may also be amended from time to time by the
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
manner or eliminating any of the provisions of this Agreement, or of modifying
in any manner the rights of the Securityholders; provided, however, that no such
amendment shall (i) reduce in any manner the amount of, or delay the timing of,
collections of payments on Loans 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 interests of any of the
holders of the Securities in any manner other than as described in clause (i),
without the consent of the holders of 100% of the Securities, or (iii) reduce
the percentage of the Securities, the consent of which is required for any such
amendment, without the consent of the holders of 100% of the Securities.

          (c) It shall not be necessary for the consent of Securityholders under
this Section to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent shall approve the substance thereof.

     Prior to the execution of any amendment to this Agreement, the Issuer and
the Indenture Trustee shall be entitled to receive and rely upon an Opinion of
Counsel stating that the execution of such amendment is authorized or permitted
by this Agreement. The Issuer and the Indenture Trustee may, but shall not be
obligated to, enter into any such amendment which affects the Issuer's own
rights, duties or immunities of the Issuer or the Indenture Trustee, as the case
may be, under this Agreement.

appropriate public offices for real property records in all of the counties or
other comparable jurisdictions in which any or all of the Mortgaged Property is

<PAGE>

available to the Note Agent 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 Note Agent may
purchase Notes based solely upon the information provided by the Loan Originator
to the Note Agent in the Loan Schedule and the representations, warranties and
covenants contained herein, and that the Note Agent, 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 Note Agent 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 Note Agent and any third party
underwriter in connection with such underwriting, including, but not limited to,
providing the Note Agent 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 Note
Agent for any and all reasonable out-of-pocket costs and expenses incurred by
the Note Agent in connection with the Note Agent'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 Note Agent 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 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 Note
Agent shall, prior to disclosure thereof, notify the Loan Originator of any
request for disclosure of any such non-public information. The Note Agent
further agrees not to use any such non-public information for any purpose
unrelated to this Agreement and that the Note Agent 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 Note Agent 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 Note Agent 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) or to
Rating Agencies or liquidity providers in the course of the Receiving Party's
business and only to the extent required for such Person's performance of their
respective evaluation of the Receiving Party's financial condition, 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.

     Each Receiving Party shall be responsible for any breach of this Section
11.17 by its Information Recipients. The Note Agent 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


                                       77

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.

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

or personally, to perform any covenant either expressed or implied contained

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 Note Agent or the
Majority Noteholders or any of their Affiliates and the Issuer, the Depositor,
the Loan Originator or the Servicer. None of the Note Agent, the Majority
Noteholders or any of their Affiliates shall be liable for any acts or actions

limitation, any Securitization pursuant to Section 3.06, any Loan Originator Put
