                  SALE AND SERVICING AGREEMENT, dated as of June 1, 2004, (the

                  WHEREAS, the Depositor has purchased such Mortgage Loans from
the Seller and is willing to sell such Mortgage Loans to the Issuer;

                  WHEREAS, the Servicer is willing to service such Mortgage

                  NOW, THEREFORE, in consideration of the promises and mutual
covenants herein contained, the parties hereto agree as follows:

                                    ARTICLE I

         Section 1.02. Other Definitional Provisions.

         (a) All terms defined in this Agreement shall have the defined meanings

                                   ARTICLE II

                          CONVEYANCE OF MORTGAGE LOANS;
                           ORIGINAL ISSUANCE OF NOTES;
                                  TAX TREATMENT

         Section 2.01. Conveyance of Mortgage Loans; Retention of Obligation to
Fund Advances Under Credit Line Agreements.

         (a) In consideration of the Issuer's delivery to or upon the order of
the Depositor on the Closing Date of the net proceeds from the sale of the Notes
and the Class O Certificates and the other amounts to be distributed from time
to time to the Depositor in accordance with the terms of this Agreement and the
Indenture, together with the issuance of the Class L Certificates and the
additional consideration for the benefit of the Servicer as set forth in Section
3.08 hereof, the Depositor, concurrently with the execution and delivery of this
Agreement, hereby sells, transfers, assigns, sets over and otherwise conveys to
the Issuer, without recourse (subject to Sections 2.03 and 2.05), all of its
right, title and interest in and to (i) each Mortgage Loan, including its
Principal Balance (including any Additional Balances related thereto) and all
collections in respect of the Mortgage Loans conveyed to the Trust and received
(or, in the case of Interest Collections, due) (A) in the case of Interest
Collections, with respect to the Principal Balance thereof as of such date,
after the close of business on the Cut-Off Date and (B) in the case of all
Principal Collections and Interest Collections on Additional Balances created
after the Cut-Off Date, after the close of business on the Issue Date; (ii) the
Depositor's rights under the Mortgage Loan Purchase and Sale Agreement and the
Purchase and Servicing Agreements; (iii) property that secured a Mortgage Loan
that is acquired by foreclosure or deed in lieu of foreclosure; (iv) the
Depositor's rights under the hazard insurance policies; (v) the Policy; (vi) the
Collection Account and the Distribution Account; and (vii) any proceeds of the
foregoing and any other Trust Property and all other assets included or to be
included in the Trust for the benefit of Noteholders, the Residual
Certificateholders and the Insurer; provided, however, neither the Indenture
Trustee nor the Trust assumes or shall assume the obligation under any Credit
Line Agreement that provides for the funding of future advances to the Mortgagor
thereunder, and neither the Trust nor the Indenture Trustee shall be obligated
or permitted to

                                       2
<PAGE>

fund any such future advances. With respect to the Mortgage Loans, Additional
Balances shall be part of the related Principal Balance and are hereby
transferred to the Trust on the Closing Date pursuant to this Section 2.01, and
are therefore part of the Trust Property. On or prior to the Closing Date, the
Depositor shall cause the Insurer to deliver the Policy to the Indenture Trustee
for the benefit of the Noteholders. It is the intention of the Depositor that
the transfer and assignment contemplated by this Agreement shall constitute a
sale of the Mortgage Loans and other Trust Property from the Depositor to the
Issuer and that such sale should constitute a valid transfer and assignment of
the Mortgage Loans and other Trust Property to the Issuer and the beneficial
interest in and title to the Mortgage Loans and the other Trust Property shall
not be part of the Depositor's estate in the event of the filing of a bankruptcy
petition by or against the Depositor under any bankruptcy law. In the event
that, notwithstanding the intent of the Depositor, the transfer and assignment
contemplated hereby is held not to be a sale, this Agreement shall constitute a
grant of a security interest in the property referred to in this Section 2.01
for the benefit of the Noteholders, the Residual Certificateholders and the
Insurer. On the first day of the Collection Period in which the commencement of
the Rapid Amortization Period occurs, any Additional Balance Contributed Amount
shall be converted into a capital contribution to the Issuer evidenced by the
Class L Certificates and any Additional Balances thereafter created shall result
in a credit for a capital contribution to the Issuer evidenced by the Class L
Certificates.

         (b) Each of the Servicer and the Depositor agrees to take or cause to
be taken such actions and execute such documents (including, without limitation,
the filing of all necessary continuation statements for the UCC-1 financing
statements filed in the States of California, Delaware and New York,
respectively, which shall have been filed on or as of the Closing Date)
describing the Issue Date Principal Balances and Additional Balances and naming
(i) in the case of the Issue Date Principal Balances, (A) the Seller as debtor
and the Depositor as secured party, (B) the Depositor as debtor and the Issuer
as secured party and (ii) in the case of Additional Balances, (A) the Servicer
as debtor and the Depositor as secured party, and (B) the Depositor as debtor
and the Issuer as secured party, and any amendments to UCC-1 financing
statements required to reflect a change in the name or corporate structure of
the Issuer, the Servicer, the Seller or the Depositor or the filing of any
additional UCC-1 financing statements due to the change in the principal office
of the Servicer, the Depositor or the Seller (within 10 days of any event
necessitating such filing) as are necessary to perfect and protect the
Noteholders' and the Insurer's interests in each Issue Date Principal Balance
and Additional Balance and the proceeds thereof (other than maintaining
possession by the Custodian of the Mortgage Loans and the Mortgage Files).

         (c) In connection with such transfer and assignment, the Seller shall
deliver or cause to the delivered to the Custodian on behalf of the Indenture
Trustee the Mortgage File (as defined in the Custody Agreement) with respect to
each Mortgage Loan, including all documents identified in Exhibit 2 to the
Custody Agreement (the "Related Documents").

         The Depositor hereby confirms to the Indenture Trustee that it has
caused the portions of the Electronic Ledgers relating to the Mortgage Loans as
of the Closing Date to be clearly and unambiguously marked, and has made, or
will make, the appropriate entries in its general accounting records to indicate
that such Mortgage Loans have been transferred to the Trust. The Servicer hereby
confirms to the Indenture Trustee that it has clearly and unambiguously made

                                       3
<PAGE>

appropriate entries in its general accounting records indicating that such
Mortgage Loans constitute part of the Trust Property and are serviced by it on
behalf of the Trust in accordance with the terms hereof.

         (d) Notwithstanding the characterization of the Notes as debt for
federal, state and local income and franchise tax purposes, the parties hereto
intend to treat the transfer of the Mortgage Loans to the Trust as provided
herein as a sale, for certain non-tax purposes, of all the Depositor's right,
title and interest in and to the Mortgage Loans, whether now existing or
hereafter created, and the other property described above and all proceeds
thereof. In the event such transfer is deemed not to be a sale for such
purposes, the Depositor grants to the Trust, a security interest in all of such
party's right, title and interest in, to and under the Mortgage Loans, whether
now existing or hereafter created, and the other property described above and
all proceeds thereof; and this Agreement shall constitute a security agreement
under applicable law.

         (e) The Indenture Trustee shall cause the Custodian to review the
Mortgage Files, produce the related certifications and take the other steps
required under Section 2.3 of the Custody Agreement.

         Neither the Custodian nor the Indenture Trustee shall have any
responsibility for reviewing any Mortgage File except as expressly provided in
the Custody Agreement or in this Section 2.01, respectively. In reviewing any
Mortgage File pursuant to this Section, the Indenture Trustee and the Custodian
shall have no responsibility for determining whether any document is valid and
binding, whether the text of any assignment or endorsement is in proper or
recordable form (except, if applicable, to determine if the Indenture Trustee is
the assignee or endorsee), 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, whether any Person
executing any document is authorized to do so or whether any signature thereon
is genuine, but shall only be required to determine whether a document has been
executed, that it appears to be what it purports to be, and, where applicable,
that it purports to be recorded.

         Upon its receipt of written notice from the Servicer or the Insurer
that a Recordation Event has occurred, the Indenture Trustee shall take all
necessary steps to prepare and submit for recordation an Assignment of Mortgage
(or a blanket Assignment of Mortgage covering multiple Mortgage Loans if the
same is permitted in any applicable jurisdiction) at the expense and on behalf
of the Servicer or, if the Servicer fails to pay such amounts or is no longer a
party hereto, pursuant to Section 6.7 and 8.7(b) of the Indenture.

         (f) The Seller shall sell, assign, transfer, set over and otherwise
convey without recourse to the Indenture Trustee all right, title and interest
of the Seller in and to any Eligible Substitute Mortgage Loan delivered to the
Indenture Trustee or the Custodian on behalf of the Trust by the Seller pursuant
to Section 2.03 or Section 2.05 hereof and all its right, title and interest to
principal collected and interest accruing on such Eligible Substitute Mortgage
Loan on and after the applicable Substitute Cut-Off Date; provided, however,
that the Seller shall reserve and retain all right, title and interest in and to
payments of interest due on such Eligible Substitute Mortgage Loan prior to the
applicable Substitute Cut-Off Date; provided, further, that

                                       4
<PAGE>

neither the Trust nor the Indenture Trustee shall be obligated to fund any
future advances to the related Mortgagor under such Eligible Substitute Mortgage
Loan.

         In connection with any transfer and assignment of an Eligible
Substitute Mortgage Loan to the Indenture Trustee on behalf of the Trust, the
Seller agrees to cause to be delivered to the Custodian on behalf of the
Indenture Trustee the items described in Section 2.01(c) on the date of such
transfer and assignment or, if a later delivery time is permitted by Section
2.01(c), then no later than such later delivery time.

         (g) Each Defective Mortgage Loan that is required to be repurchased or
substituted pursuant to the provisions this Agreement shall, upon such
repurchase or substitution in accordance with the provisions hereof, be released
from the Trust and from the lien created by the Indenture. As to each Mortgage
Loan released from the Trust in connection with the repurchase thereof or the
conveyance of an Eligible Substitute Mortgage Loan therefor, the Seller shall
prepare, and the Indenture Trustee, on behalf of the Trust, will execute, such
documents as are necessary to transfer, assign, set over and otherwise convey
without recourse, to or upon the order of the Seller, all of its right, title
and interest in and to such released Mortgage Loan and all the Trust's right
title and interest to principal collected and interest accruing on such released
Mortgage Loan on and after the first day of the calendar month in which such
Mortgage Loan is released; provided, however, that the Trust shall reserve and
retain all right, title and interest in and to payments of principal and
interest collected on such released Mortgage Loan prior to such date.

         Section 2.02. Further Encumbrance of Trust Property.

         (a) Immediately upon the conveyance to the Trust by the Depositor of
any item of the Trust Property pursuant to Section 2.01, all right, title and
interest of the Depositor in and to such item of Trust Property shall terminate,
and all such right, title and interest shall vest in the Trust, in accordance
with the Trust Agreement and Sections 3802 and 3805 of the Delaware Statutory
Trust Act (12 Del. Code, Section 3801 et seq.).

         (b) Immediately upon the vesting of the Trust Property in the Trust,
the Trust shall have the sole right to pledge or otherwise encumber, such Trust
Property. Pursuant to the Indenture and contemporaneously with such property
vesting in the Trust pursuant to (a) above, the Trust shall grant a security
interest in the Trust Property to secure the repayment of the Issuer Secured
Obligations. The Residual Certificates shall represent the beneficial ownership
interest in the Trust Property, and the Residual Certificateholders shall be
entitled to receive distributions with respect thereto as set forth herein and
in the Indenture and Trust Agreement.

         (c) Prior to the payment in full on the Notes, the payment of all
amounts due to the Insurer under the Insurance Agreement, the termination of the
Policy and the surrender of the Policy by the Indenture Trustee to the Insurer,
the Indenture Trustee (or the Custodian, on behalf of the Indenture Trustee)
shall hold the Trust Property on behalf of the Noteholders. Following the
payment in full of the Notes and the payment of all amounts due to the Insurer
under the Insurance Agreement, and the release and discharge of the Indenture,
all covenants of the Issuer under Article III of the Indenture shall, until
payment in full of the Residual Certificates, remain as covenants of the Issuer
for the benefit of the Residual Certificateholders, enforceable by the

                                       5
<PAGE>

Residual Certificateholders to the same extent as such covenants were
enforceable by the Insurer and the Noteholders prior to the discharge of the
Indenture. Any rights of the Indenture Trustee under Article III of the
Indenture, following the discharge of the Indenture, shall vest in the Residual
Certificateholders.

         Section 2.03. Acknowledgement of Receipt; Certain Substitution of
Mortgage Loans.

         (a) The Indenture Trustee shall, at such time as there are no Notes
outstanding and all sums due to (i) the Indenture Trustee or any agent or
counsel thereof pursuant to the Indenture, (ii) the Indenture Trustee pursuant
to this Agreement and (iii) the Insurer pursuant to the Insurance Agreement have
been paid, release any portions of the Trust Property to the Issuer in
accordance with the provisions of Sections 2.8 and 8.2 of the Indenture.

         (b) The Issuer hereby acknowledges its receipt of the Policy and the
Mortgage Loans, and declares that the Indenture Trustee (or the Custodian, on
behalf of the Indenture Trustee) holds and will hold such instruments, and to
the extent that any documents are delivered to it pursuant to Section 2.01, will
hold such documents, and all amounts received by it thereunder and hereunder, in
trust, upon the terms herein set forth, for the use and benefit of all present
and future Noteholders, and the Insurer. If the time to cure any defect in
respect of any Mortgage Loan of which the Indenture Trustee, the Custodian or
the Insurer has notified the Depositor and the Seller following the review
pursuant to Section 2.01 has expired or if at any time any loss is suffered by
the Issuer or the Indenture Trustee on behalf of the Noteholders or the Insurer,
in respect of any Mortgage Loan as a result of (i) a defect in any document
constituting a part of its Mortgage File or (ii) an Assignment of Mortgage to
the Indenture Trustee not having been recorded as required by Section 2.01, then
on the next succeeding Business Day, the Seller shall (i) substitute in lieu of
such Mortgage Loan Eligible Substitute Mortgage Loans, and deliver the
Substitution Amount applicable thereto to the Servicer for deposit in the
Collection Account or (ii) purchase such Mortgage Loan at a purchase price equal
to the Loan Purchase Price thereof, which purchase price shall be delivered to
the Servicer for deposit in the Collection Account. The Seller intends any
conveyance of Eligible Substitute Mortgage Loans to the Indenture Trustee to
constitute a sale, but in the event the conveyance is held not to be a sale,
this Agreement shall constitute a grant of a security interest in the Eligible
Substitute Mortgage Loans and the proceeds thereof for the benefit of the
Indenture Trustee, Noteholders and the Insurer. Upon receipt of any Eligible
Substitute Mortgage Loan or of written notification signed by a Servicing
Officer to the effect that the Loan Purchase Price in respect of a Defective
Mortgage Loan has been deposited into the Collection Account, then as promptly
as practicable, the Indenture Trustee, on behalf of the Trust, shall execute
such documents and instruments of transfer presented by the Seller, in each case
without recourse, representation or warranty, and take such other actions as
shall reasonably be requested by the Seller to effect such transfer by the Trust
of such Defective Mortgage Loan pursuant to this Section. It is understood and
agreed that the obligation of the Seller to accept a transfer of a Defective
Mortgage Loan and to either convey an Eligible Substitute Mortgage Loan or to
make a deposit of any related Loan Purchase Price into the Collection Account
shall constitute the sole remedy respecting such defect available to Noteholders
and the Indenture Trustee against the Seller.

                                       6
<PAGE>

         (c) As to any Eligible Substitute Mortgage Loan, the Seller shall, if
required to deliver any such Eligible Substitute Mortgage Loan, deliver to the
Custodian with respect to such Eligible Substitute Mortgage Loan such documents
and agreements as are required to be held by the Custodian in accordance with
the Custody Agreement. For any Collection Period during which the Seller
substitutes one or more Eligible Substitute Mortgage Loans, the Servicer shall
determine the Substitution Amount which amount shall be deposited by the Seller
in the Collection Account at the time of substitution. All amounts received in
respect of the Eligible Substitute Mortgage Loan during the Collection Period in
which the circumstances giving rise to such substitution occur shall not be a
part of the Trust Property and shall not be deposited by the Servicer in the
Collection Account. All amounts received by the Servicer during the Collection
Period in which the circumstances giving rise to such substitution occur in
respect of any Defective Mortgage Loan so removed by the Trust shall be
deposited by the Servicer in the Collection Account. Upon such substitution, the
Eligible Substitute Mortgage Loan shall be subject to the terms of this
Agreement in all respects, and the Seller shall be deemed (i) to have made with
respect to such Eligible Substitute Mortgage Loan as of the date of
substitution, the covenants, representations and warranties set forth in Section
2.05 and (ii) to have certified that such Mortgage Loan is an Eligible
Substitute Mortgage Loan. The procedures applied by the Seller in selecting each
Eligible Substitute Mortgage Loan shall not be materially adverse to the
interests of the Indenture Trustee, the Noteholders or the Insurer.

         The Servicer, promptly following the transfer of a Defective Mortgage
Loan from, or an Eligible Substitute Mortgage Loan to, the Trust pursuant to
this Section, shall amend the Mortgage Loan Schedule and make appropriate
entries in its general account records to reflect such transfer. The Servicer
shall, following such transfer, appropriately mark its records to indicate that
it is no longer servicing such Defective Mortgage Loan on behalf of the Trust.
The Seller, promptly following such transfer, shall make appropriate entries in
its general account records to reflect such transfer.

         Section 2.04. Representations and Warranties Regarding the Seller and
the Depositor.

         (a) The Seller hereby represents and warrants to the Indenture Trustee
and the Insurer as of the Closing Date or such other date as is specified, that:

                  (i) the Seller is a corporation duly organized, validly
         existing and in good standing under the laws governing its creation and
         existence and has full corporate power and authority to own its
         property, to carry on its business as presently conducted, to enter
         into and perform its obligations under this Agreement, and to create
         the trust pursuant hereto;

                  (ii) the execution and delivery by the Seller of this
         Agreement have been duly authorized by all necessary corporate action
         on the part of the Seller; neither the execution and delivery of this
         Agreement, nor the consummation of the transactions herein
         contemplated, nor compliance with the provisions hereof, will conflict
         with or result in a breach of, or constitute a default under, any of
         the provisions of any law, governmental rule, regulation, judgment,
         decree or order binding on the Seller or its properties or the
         certificate of incorporation or bylaws of the Seller;

                                       7
<PAGE>

                  (iii) the execution, delivery and performance by the Seller of
         this Agreement and the consummation of the transactions contemplated
         hereby do not require the consent or approval of, the giving of notice
         to, the registration with, or the taking of any other action in respect
         of, any state, federal or other governmental authority or agency,
         except such as has been obtained, given, effected or taken prior to the
         date hereof;

                  (iv) this Agreement has been duly executed and delivered by
         the Seller and, assuming due authorization, execution and delivery by
         the Depositor, the Servicer, the Issuer and the Indenture Trustee,
         constitutes a valid and binding obligation of the Seller enforceable
         against it in accordance with its terms except as such enforceability
         may be subject to (A) applicable bankruptcy and insolvency laws and
         other similar laws affecting the enforcement of the rights of creditors
         generally and (B) general principles of equity regardless of whether
         such enforcement is considered in a proceeding in equity or at law; and

                  (v) there are no actions, suits or proceedings pending or, to
         the knowledge of the Seller, threatened or likely to be asserted
         against or affecting the Seller, before or by any court, administrative
         agency, arbitrator or governmental body (A) with respect to any of the
         transactions contemplated by this Agreement or (B) with respect to any
         other matter which in the judgment of the Seller will be determined
         adversely to the Seller and will if determined adversely to the Seller
         materially and adversely affect it or its business, assets, operations
         or condition, financial or otherwise, or adversely affect its ability
         to perform its obligations under this Agreement.

                  The representations and warranties set forth in this Section
         2.04(a) shall survive the sale and assignment of the Mortgage Loans to
         the Trust. Upon discovery of a breach of any representations and
         warranties which materially and adversely affects the interests of the
         Noteholders or the Insurer, the person discovering such breach shall
         give written notice within five (5) days of discovery to the other
         parties and the Insurer. Within 30 days of its discovery or its receipt
         of notice of breach, or, with the prior written consent of a
         Responsible Officer of the Indenture Trustee and the Insurer, such
         longer period specified in such consent, the Seller shall cure such
         breach if such breach is curable and no material adverse effect would
         result to the Insurer, the Indenture Trustee, the Trust or the
         Noteholders.

         (b) The Depositor hereby represents and warrants to the Indenture
Trustee and the Insurer as of the Closing Date or such other date as is
specified, that:

                  (i) the Depositor is a corporation duly organized, validly
         existing and in good standing under the laws governing its creation and
         existence and has full corporate power and authority to own its
         property, to carry on its business as presently conducted, to enter
         into and perform its obligations under this Agreement, and to create
         the trust pursuant hereto;

                  (ii) the execution and delivery by the Depositor of this
         Agreement have been duly authorized by all necessary corporate action
         on the part of the Depositor;

                                       8
<PAGE>

         neither the execution and delivery of this Agreement, nor the
         consummation of the transactions herein contemplated, nor compliance
         with the provisions hereof, will conflict with or result in a breach
         of, or constitute a default under, any of the provisions of any law,
         governmental rule, regulation, judgment, decree or order binding on the
         Depositor or its properties or the certificate of incorporation or
         bylaws of the Depositor;

                  (iii) the execution, delivery and performance by the Depositor
         of this Agreement and the consummation of the transactions contemplated
         hereby do not require the consent or approval of, the giving of notice
         to, the registration with, or the taking of any other action in respect
         of, any state, federal or other governmental authority or agency,
         except such as has been obtained, given, effected or taken prior to the
         date hereof;

                  (iv) this Agreement has been duly executed and delivered by
         the Depositor and, assuming due authorization, execution and delivery
         by the Seller, the Servicer, the Issuer and the Indenture Trustee,
         constitutes a valid and binding obligation of the Depositor enforceable
         against it in accordance with its terms except as such enforceability
         may be subject to (A) applicable bankruptcy and insolvency laws and
         other similar laws affecting the enforcement of the rights of creditors
         generally and (B) general principles of equity regardless of whether
         such enforcement is considered in a proceeding in equity or at law; and

                  (v) there are no actions, suits or proceedings pending or, to
         the knowledge of the Depositor, threatened or likely to be asserted
         against or affecting the Depositor, before or by any court,
         administrative agency, arbitrator or governmental body (A) with respect
         to any of the transactions contemplated by this Agreement or (B) with
         respect to any other matter which in the judgment of the Depositor will
         be determined adversely to the Depositor and will if determined
         adversely to the Depositor materially and adversely affect it or its
         business, assets, operations or condition, financial or otherwise, or
         adversely affect its ability to perform its obligations under this
         Agreement.

         The representations and warranties set forth in this Section 2.04(b)
shall survive the sale and assignment of the Mortgage Loans to the Trust. Upon
discovery of a breach of any representations and warranties which materially and
adversely affects the interests of the Noteholders or the Insurer, the person
discovering such breach shall give written notice within five (5) days of
discovery to the other parties and the Insurer. Within 30 days of its discovery
or its receipt of notice of breach, or, with the prior written consent of a
Responsible Officer of the Indenture Trustee and the Insurer, such longer period
specified in such consent, the Depositor shall cure such breach if such breach
is curable and no material adverse effect would result to the Insurer, the
Indenture Trustee, the Trust or the Noteholders.

         Section 2.05. Representations and Warranties of the Seller Regarding
the Mortgage Loans; Removal of Certain Mortgage Loans.

         (a) The Seller hereby makes, with respect to each Mortgage Loan, the
representations and warranties set forth in Sections 2.1(a), (b) (incorporating
by reference Schedule A) and (d) of the Mortgage Loan Purchase and Sale
Agreement, on which the Issuer is deemed to have relied

                                       9
<PAGE>

in acquiring the Mortgage Loans and upon which the Insurer is deemed to rely in
issuing the Policy and the Servicer is deemed to rely in entering into this
Agreement. Such representations and warranties speak as of the execution and
delivery of this Agreement, as of the Closing Date with respect to the Mortgage
Loans and as of the related Transfer Date with respect to the Eligible
Substitute Mortgage Loans, but shall survive the sale, transfer, and assignment
of the Mortgage Loans to the Issuer and the pledge thereof to the Indenture
Trustee pursuant to the Indenture.

         With respect to each of the representations and warranties incorporated
by reference in this Section 2.05 that are made to the best of the Seller's
knowledge or as to which the Seller has no knowledge, if it is discovered by the
Seller, the Servicer, the Insurer, or a Responsible Officer of the Indenture
Trustee that the substance of such representation and warranty is inaccurate and
such inaccuracy materially and adversely affects the value of the related
Mortgage Loan then, notwithstanding the Seller's lack of knowledge with respect
to the substance of such representation and warranty being inaccurate at the
time the representation or warranty was made, such inaccuracy shall be deemed a
breach of the applicable representation or warranty. Notwithstanding the
foregoing, a breach of any of the representations and warranties set forth in
clause (xxxii) or clause (xxxiii) of Schedule A to the Mortgage Loan Purchase
and Sale Agreement will be deemed to materially and adversely affect the value
of the related Mortgage Loan.

         (b) It is understood and agreed that the representations and warranties
incorporated by reference in this Section 2.05 shall survive delivery of the
respective Mortgage Files to the Custodian pursuant to Section 2.01 and the
Custody Agreement and the termination of the rights and obligations of the
Servicer pursuant to Section 5.04 or 6.02. Upon discovery by the Depositor, the
Seller, the Servicer, the Insurer, a Responsible Officer of the Indenture
Trustee or a Class L Certificateholder of a breach of any of the foregoing
representations and warranties, without regard to any limitation set forth
therein concerning the knowledge of the Seller as to the facts stated therein,
which materially and adversely affects the interests of the Trust or the
Noteholders or the Insurer in the related Mortgage Loans, the party discovering
such breach shall give prompt written notice to the other parties, to the Class
L Certificateholders and to the Insurer. Within 90 days of its discovery or its
receipt of notice of such breach, the Seller shall use all reasonable efforts to
cure such breach or shall, not later than the Business Day next preceding the
Payment Date in the month following the Collection Period in which any such cure
period expired (or such later date that is acceptable to the Insurer as
evidenced by its written consents), either (a) repurchase such Mortgage Loan
from the Trust at the Loan Purchase Price or (b) substitute an Eligible
Substitute Mortgage Loan, each in the same manner and subject to the same
conditions as set forth in Section 2.03 and the representations and warranties
set forth in Section 2.04; provided, however, that the cure for any breach of a
representation and warranty relating to the characteristics of the Mortgage
Loans in the aggregate shall be a repurchase of or substitution for only the
Mortgage Loans necessary to cause such characteristics to be in compliance with
the related representation and warranty. Upon accepting such transfer and making
any required deposit into the Collection Account or substitution of an Eligible
Substitute Mortgage Loans, as the case may be, the Seller shall be entitled to
receive an instrument of assignment or transfer from the Indenture Trustee, on
behalf of the Trust, to the same extent as set forth in Section 2.03 with
respect to the transfer of Mortgage Loans under that Section. The Insurer shall
be notified of any substitution of an Eligible Substitute Mortgage Loan.

                                       10
<PAGE>

         It is understood and agreed that the obligation of the Seller to
repurchase a Mortgage Loan as to which a breach has occurred and is continuing
and deposit in the Collection Account the Loan Purchase Price or to substitute
an Eligible Substitute Mortgage Loan, as the case may be, shall constitute the
sole remedy against the Seller respecting such breach available to Noteholders,
the Indenture Trustee on behalf of Noteholders and the Insurer; provided,
however, that the Seller shall defend and indemnify the Depositor, the Indenture
Trustee, the Insurer and the Noteholders against all reasonable costs and
expenses, and all losses, damages, claims and liabilities, including reasonable
fees and expenses of counsel and the amount of any settlement entered into with
the consent of the Seller (such consent not to be unreasonably withheld), which
may be asserted against or incurred by any of them as a result of any
third-party action arising out of any breach of any such representation and
warranty. Notwithstanding the foregoing, with regard to any breach of the
representation and warranty set forth in clause (xxxii) or clause (xxxiii) of
Schedule A to the Mortgage Loan Purchase and Sale Agreement, the Seller shall
pay to the Trust the Loan Purchase Price.

         Section 2.06. Covenants of the Depositor. The Depositor hereby
covenants that:

         (a) Security Interests. The Depositor will not sell, pledge, assign or
transfer to any other Person, or grant, create, incur, assume or suffer to exist
any Lien on any Mortgage Loans, whether now existing or hereafter created, or
any interest therein; the Depositor will notify the Indenture Trustee and the
Insurer of the existence of any Lien on any Mortgage Loans immediately upon
discovery thereof; and the Depositor will defend the Trust's right, title and
interest (including the Trust's security interest) in, to and under the Mortgage
Loans, whether now existing or hereafter created, against all claims of third
parties claiming through or under the Depositor; provided, however, that nothing
in this Section 2.06(a) shall prevent or be deemed to prohibit the Depositor
from suffering to exist upon any of the Mortgage Loans any Liens for municipal
or other local taxes and other governmental charges if such taxes or
governmental charges shall not at the time be due and payable or if the
Depositor shall currently be contesting the validity thereof in good faith by
appropriate proceedings and shall have set aside on its books adequate reserves
with respect thereto.

         (b) UCC-1 Financing Statements. On the Closing Date with respect to the
Mortgage Loans and, to the extent not already included in such filing, on the
applicable Transfer Date with respect to any Eligible Substitute Mortgage Loans,
the Depositor will file UCC-1 financing statements with respect to such Mortgage
Loans.

         (c) Negative Pledge. The Depositor hereby agrees not to transfer,
assign, exchange, pledge, finance, hypothecate, grant a security interest in or
otherwise convey the Residual Certificates except in accordance with Sections
5.04 and 6.02 hereof and in accordance with the Insurance Agreement and the
Trust Agreement.

         (d) Downgrading. The Depositor will not engage in any activity which
would result in a downgrading or withdrawal of the ratings on the Notes without
regard to the effect of the Policy.

         (e) Amendment to Certificate of Incorporation. The Depositor will not
amend its certificate of incorporation without prior written notice to the
Indenture Trustee and the Rating

                                       11
<PAGE>

Agencies and the prior written consent of the Insurer which consent shall not be
unreasonably withheld.

         (f) Principal Place of Business. The Depositor's principal place of
business is in California, and the Depositor will not change its principal place
of business without prior written notice to the Indenture Trustee, the Rating
Agencies and the Insurer.

         (g) No Notification of Mortgagors. The Depositor hereby agrees not to
notify Mortgagors of the transfer of the Mortgage Loans to the Trust unless
required by the terms of the Mortgage Loans or applicable law.

         Section 2.07. Removal of Mortgage Loans at Election of Issuer.

         Subject to the conditions set forth below and Section 8.2 of the
Indenture, the Issuer may, but shall not be obligated to, require the removal of
Mortgage Loans, from time to time, as of the close of business on a Payment Date
(each, a "Removal Date"). On the tenth Business Day (the "Removal Notice Date")
prior to the Removal Date designated in such notice, the Issuer shall give the
Indenture Trustee, the Insurer and the Servicer a notice of the proposed removal
that contains a list of the Mortgage Loans in the Pool to be removed. Such
removal of Mortgage Loans shall be permitted upon satisfaction of the following
conditions:

                  (i) Neither a Rapid Amortization Event nor an Event of Default
         shall have occurred;

                  (ii) On the Removal Date, the Overcollateralization Amount
         (after giving effect to the removal of the Mortgage Loans proposed to
         be removed) equals or exceeds the Specified Overcollateralization
         Amount;

                  (iii) The transfer of such Mortgage Loans on any Removal Date
         shall not, in the reasonable belief of the Manager, on behalf of the
         Issuer, cause a Rapid Amortization Event or an Event of Default to
         occur or an event which with notice or lapse of time or both would
         constitute such a Rapid Amortization Event or Event of Default;

                  (iv) On or before the Removal Date, the Issuer shall have
         delivered to the Indenture Trustee a revised Mortgage Loan Schedule,
         reflecting the proposed transfer and the Removal Date, and the Servicer
         shall have marked its records in accordance with the Master Servicing
         Agreement to show that the Mortgage Loans removed are no longer
         included in the Pool;

                  (v) The Manager, on behalf of the Issuer, shall represent and
         warrant that its selection procedures are random and no selection
         procedures reasonably believed by the Manager to be adverse to the
         interests of the Noteholders or the Insurer were utilized in selecting
         the Mortgage Loans to be removed from the Pool;

                  (vi) In connection with each such removal of Mortgage Loans
         pursuant to this Section, each Rating Agency shall have received on or
         prior to the related Removal Notice Date notice of such proposed
         removal of Mortgage Loans and, prior to the Removal Date, shall have
         notified the Indenture Trustee and the Insurer in writing that

                                       12
<PAGE>

         such removal of Mortgage Loans would not result in a reduction or
         withdrawal of its then current ratings of the Notes, without regard to
         the Policy; and

                  (vii) The Manager, on behalf of the Issuer, shall have
         delivered to the Indenture Trustee and the Insurer an Officer's
         Certificate certifying that the items set forth in subparagraphs (i)
         through (vi), inclusive, have been performed or are true and correct,
         as the case may be. The Indenture Trustee and the Insurer may
         conclusively rely on such Officer's Certificate, shall have no duty to
         make inquiries with regard to the matters set forth therein and shall
         incur no liability in so relying.

                  (viii) The Insurer shall have been given an opportunity to
         review any Mortgage Loans proposed to be removed by the Issuer and
         shall have consented to such removal.

         Upon receiving the requisite information from the Manager, on behalf of
the Issuer, the Servicer shall perform in a timely manner those acts required of
it, as specified above. Upon satisfaction of the above conditions, on the
Removal Date the Indenture Trustee shall deliver, or cause to be delivered, to
or to the order of the Issuer the Mortgage File for each Mortgage Loan being so
transferred, and the Indenture Trustee shall execute and deliver to or to the
order of the Issuer such other documents prepared by the Issuer as shall be
reasonably necessary to remove such Mortgage Loans from the Pool. Any such
removal of Mortgage Loans shall be without recourse, representation or warranty
by or of the Indenture Trustee to the Issuer. The review right given to the
Insurer in clause (viii), above, must be completed prior to the Removal Date.

         Section 2.08. Execution and Authentication of Notes. The Indenture
Trustee, on behalf of the Issuer, has caused to be authenticated and delivered
to or upon the order of the Depositor, in exchange for the Collateral,
concurrently with the sale, assignment and conveyance to the Indenture Trustee
of the Collateral, one class of Notes in authorized denominations.

         Section 2.09. Tax Treatment. It is the intention of the Depositor and
the Residual Certificateholders that (i) the Notes be classified indebtedness of
the Issuer and (ii) the Residual Certificates be classified as equity in the
Issuer for federal, state and local income and franchise tax purposes and for
purposes of any other tax imposed on or measured by income. The Depositor, the
Indenture Trustee and each Noteholder (or Note Owner) by acceptance of its Note
(or, in the case of a Note Owner, by virtue of such Note Owner's acquisition of
a beneficial interest therein) agrees to treat the Notes (or beneficial interest
therein), for purposes of federal, state and local income or franchise taxes and
any other tax imposed on or measured by income, as indebtedness of the Issuer
secured by the assets of the Trust and to report the transactions contemplated
by this Agreement on all applicable tax returns in a manner consistent with such
treatment. Each Noteholder agrees that it will cause any Note Owner acquiring an
interest in a Note through it to comply with this Agreement as to treatment of
the Notes as indebtedness for federal, state and local income and franchise tax
purposes and for purposes of any other tax imposed on or measured by income. The
Indenture Trustee will prepare and file all tax reports required hereunder
consistent with this Agreement as required by or provided in Section 3.04.

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

         Section 3.01. The Servicer.

         (a) The Servicer is hereby authorized to act as agent for the Trust and
in such capacity shall manage, service, administer and make collections on the
Mortgage Loans and perform the other actions under this Agreement. The Servicer
shall service and administer the Mortgage Loans in accordance with the terms of
the Master Servicing Agreement. In the event of any inconsistency between this
Agreement and the Master Servicing Agreement, the terms of this Agreement shall
govern.

         (b) The Servicer hereby confirms its obligation, as Servicer, to fund
future advances to the Mortgagors pursuant to the Credit Line Agreements and
hereby sells, transfers, assigns, sets over and otherwise conveys to the
Depositor the Additional Balances so created. It is the intention of the
Servicer that the transfer of the Additional Balances to the Depositor shall
constitute a sale, but in the event that the transfer is held not to be a sale,
this Agreement shall constitute a grant of a security interest in the Additional
Balances, and the proceeds thereof, for the benefit of the Depositor.

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

         Section 3.02. Indenture Trustee to Cooperate. On or before each Payment
Date, the Servicer will notify the Indenture Trustee and the Custodian, on
behalf of the Trust, of the payment in full of the Principal Balance of any
Mortgage Loan during the preceding Collection Period, which notification shall
be by a certification (which certification shall include a statement to the
effect that all amounts received in connection with such payment which are
required to be deposited in the Collection Account pursuant to Section 3.02 have
been so deposited or credited) of a Servicing Officer. Upon any such payment in
full, the Servicer is authorized to execute, pursuant to the authorization
contained in Section 3.01, if the assignments of Mortgage have been recorded as
required hereunder, an instrument of satisfaction regarding the related
Mortgage, which instrument of satisfaction shall be recorded by the Servicer if
required by applicable law and be delivered to the Person entitled thereto. It
is understood and agreed that no expenses incurred in connection with such
instrument of satisfaction or transfer shall be reimbursed from amounts
deposited in the Collection Account. If the Indenture Trustee or the Custodian
is holding the Mortgage Files, from time to time and as appropriate for the
servicing or foreclosure of any Mortgage Loan, or in connection with the payment
in full of the Principal Balance of any Mortgage Loan, the Indenture Trustee or
the Custodian, as appropriate, shall, upon request of the Servicer in accordance
with the Custody Agreement and delivery to the Indenture Trustee and, if
applicable, the Custodian of a Request for Release substantially in the
applicable forms attached as exhibits to the Custody Agreement, release the
related Mortgage File to the Servicer and the Indenture Trustee, on behalf of
the Trust, shall execute such documents, in the forms provided by the Servicer,
as shall be necessary to the prosecution of any

                                       14
<PAGE>

such proceedings or the taking of other servicing actions. Such trust receipt
shall obligate the Servicer to return the Mortgage File to the Indenture Trustee
or the Custodian, as appropriate, when the need therefor by the Servicer no
longer exists unless the Mortgage Loan shall be liquidated, in which case, upon
receipt of a certificate of a Servicing Officer similar to that hereinabove
specified, the trust receipt shall be released by the Indenture Trustee or the
Custodian, as the case may be.

         In order to facilitate the foreclosure of the Mortgage securing any
Mortgage Loan that is in default following recordation of the Assignment of
Mortgage in accordance with the provisions hereof, the Indenture Trustee, on
behalf of the Trust, shall, if so requested in writing by the Servicer, execute
an appropriate assignment in the form provided to the Indenture Trustee, on
behalf of the Trust, by the Servicer to assign such Mortgage Loan for the
purpose of collection to the Servicer or to the related subservicer (any such
assignment shall unambiguously indicate that the assignment is for the purpose
of collection only), and, upon such assignment, the Servicer will thereupon
bring all required actions in its own name and otherwise enforce the terms of
the Mortgage Loan and deposit the Net Liquidation Proceeds, exclusive of
Foreclosure Profits, received with respect thereto in the Collection Account. In
the event that all delinquent payments due under any such Mortgage Loan are paid
by the Mortgagor and any other defaults are cured, then the Servicer shall,
within two Business Days, reassign such Mortgage Loan to the Indenture Trustee,
on behalf of the Trust, and return the related Mortgage File to the place where
it was being maintained. After such reassignment, the Servicer, if requested by
such Residual Certificateholders and if offered suitable indemnification and
reimbursement for expenses, is authorized to seek a deficiency judgment if
permitted by law against the Mortgagor under such Liquidated Mortgage Loan on
behalf of the Residual Certificateholders to the extent of any losses on
liquidation of any Mortgage Loan.

         Section 3.03. [Reserved.]

         Section 3.04. Reports to the SEC. Within 15 days after each Payment
Date, the Issuer shall, in accordance with industry standards, file with the SEC
via the Electronic Data Gathering and Retrieval System (EDGAR), a Form 8-K (or
such other form as is prescribed by the SEC) with a copy of the report of the
Noteholders for such Payment Date as an exhibit thereto. Prior to March 15, 2005
(and, if applicable, prior to March 15 of each year), the Issuer shall, in
accordance with industry standards, file with the SEC via EDGAR a Form 10-K with
respect to the Trust. In addition, the Depositor will cause its senior officer
in charge of securitization to execute the certification (the "Form 10-K
Certification") required pursuant to Rule 13a-14 under the Securities and
Exchange Act of 1934, as amended, and file the same with the SEC prior to March
15, 2005 (and if applicable, prior to March 15 of each year). To the extent any
information or exhibits required to be included in the Form 10-K are not
available by March 15, the Issuer shall file one or more amended Form 10-Ks to
include such missing information or exhibits promptly after receipt thereof by
the Issuer. Promptly following the first day legally permissible under
applicable regulations and interpretations of the SEC, the Issuer shall, in
accordance with industry standards, file with the SEC via EDGAR a Form 15
Suspension Notification with respect to the Trust, if applicable. Each of the
Servicer, the Depositor and the Indenture Trustee agree to furnish to the
Manager, on behalf of the Issuer, promptly, from time to time upon request, such
further information, reports and financial statements within its control related
to this Agreement and the Mortgage Loans as the Manager

                                       15
<PAGE>

reasonably deems appropriate to prepare and file all necessary reports with the
SEC. The Issuer (i) shall have no responsibility to file any items other than
those specified in this section and (ii) shall appoint the Manager to perform
its obligations under this Section 3.04 pursuant the Management Agreement.

         Section 3.05. Tax Returns. The Indenture Trustee shall prepare and file
any federal, state or local income and franchise tax return for the Trust as
well as any other applicable return, apply for a taxpayer identification number
on behalf of the Trust on form SS4 or by another acceptable method and file Form
8811 with respect to the Trust, each in a manner consistent with Sections
2.5(b), 2.11 and 6.1 of the Trust Agreement, Section 3.21 of the Indenture and
Section 2.09 of this Agreement. The Issuer shall treat the Mortgage Loans as its
property for all federal, state or local tax purposes and shall report all
income earned thereon (including amounts payable as fees to the Servicer) as its
income for income tax purposes. The Indenture Trustee shall prepare and file or
shall cause to be prepared and filed any tax returns required to be filed by the
Trust; the Issuer shall promptly sign such returns and deliver such returns back
to the Indenture Trustee after signature and such returns shall be filed by the
Indenture Trustee. The Indenture Trustee shall also prepare or shall cause to be
prepared all tax information required by law to be distributed to Noteholders.
In no event shall the Indenture Trustee be liable for any liabilities, costs or
expenses of the Trust, the Noteholders, the Residual Certificateholders or the
Note Owners arising under any tax law, including, without limitation, federal,
state or local income and franchise or excise taxes or any other tax imposed on
or measured by income (or any interest or penalty with respect thereto or
arising from a failure to comply therewith), except for such liabilities, costs
or expenses of the Trust resulting from (i) the Indenture Trustee's failure to
file such tax returns or (ii) an incorrect tax return prepared by the Indenture
Trustee.

         Section 3.06. [Reserved]

         Section 3.07. Matters Relating to MERS Loans.

         (a) The Servicer further is authorized and empowered by the Trust and
the Indenture Trustee and the Insurer, on behalf of the Noteholders, the Insurer
and the Indenture Trustee, in its own name or in the name of the subservicer,
when the Servicer believes it appropriate in its best judgment to register any
Mortgage Loan on the MERS System, or cause the removal from the registration of
any Mortgage Loan on the MERS System, to execute and deliver, on behalf of the
Trust, the Indenture Trustee, the Insurer and the Noteholders or any of them,
any and all instruments of assignment and other comparable instruments with
respect to such assignment or re-recording of a Mortgage in the name of MERS,
solely as nominee for the Trust and its successors and assigns.

         (b) In connection with the sale and assignment of any MERS Mortgage
Loan by the Depositor to the Issuer, the Depositor agrees that it will cause, at
the Depositor's expense, the MERS System to indicate that such Mortgage Loans
have been assigned by the Depositor to the Indenture Trustee in accordance with
the Indenture for the benefit of the Issuer Secured Parties by including (or
deleting, in the case of Mortgage Loans which are repurchased in accordance with
this Agreement) in such computer files the information required by the MERS
System to identify the series of the Notes issued in connection with such
Mortgage Loans. The Depositor further agrees that it will not, and will not
permit the Seller or the Servicer to, and the Seller and

                                       16
<PAGE>

the Servicer agree that they will not, alter the information referenced in this
paragraph with respect to any Mortgage Loan during the term of this Agreement
unless and until such Mortgage Loan is repurchased in accordance with the terms
of this Agreement. If at any time pursuant to Section 2.03 or Section 2.05 the
Seller repurchases a Mortgage Loan that is a MERS Mortgage Loan, the Servicer
shall either (i) cause MERS to execute and deliver an assignment of the Mortgage
in recordable form to transfer the Mortgage from MERS to the Seller and shall
cause such Mortgage to be removed from registration on the MERS System in
accordance with MERS' rules and regulations or (ii) cause MERS to designate on
the MERS System the Seller (or any party indicated by the Seller) as the
beneficial holder of such Mortgage Loan.

         (c) In connection with the termination or resignation of the Servicer
hereunder, either (i) the successor Servicer, including the Indenture Trustee if
the Indenture Trustee is acting as successor Servicer, shall represent and
warrant that it is a member of MERS in good standing and shall agree to comply
in all material respects with the rules and procedures of MERS in connection
with the servicing of the Mortgage Loans that are registered with MERS, or (ii)
the predecessor Servicer shall cooperate with the successor Servicer either (x)
in causing MERS to execute and deliver an assignment of Mortgage in recordable
form to transfer the Mortgage from MERS to the Trust and to execute and deliver
such other notices, documents and other instruments as may be necessary or
desirable to effect a transfer of such Mortgage Loan or servicing of such
Mortgage Loan on the MERS System to the successor Servicer or (y) in causing
MERS to designate on the MERS System the successor Servicer as the servicer of
such Mortgage Loan.

         Section 3.08. Additional Balance Payments; Class L Certificates. In
consideration of the Servicer's agreement to sell Additional Balances relating
to the Mortgage Loans to the Depositor, the Depositor shall, on the Closing
Date, cause the Issuer to deliver to (or to the order of) the Servicer the Class
L Certificates. Payment to the Servicer of the Purchase Price for each such
Additional Balance shall be made pursuant to the following: (a) reimbursements
by the Servicer pursuant to Section 4.05(iii) of the Master Servicing Agreement,
(b) monthly distributions to the Servicer, as holder of the Class L
Certificates, pursuant to Section 8.7(b) of the Indenture, (c) distributions to
the Servicer, as holder of the Class L Certificates, of Mortgage Loans removed
from the lien of the Indenture pursuant to Section 8.02 thereof and Section 2.07
hereof, and (d) credit for capital contributions to the Issuer evidenced by the
Class L Certificates.

         The Servicer shall deliver to the Indenture Trustee a request for
reimbursement of the amount of any Additional Balance Contributed Amount,
together with accrued interest thereon, two Business Days prior to the
Remittance Date (as defined in the Master Servicing Agreement).

         Section 5.02. Merger or Consolidation of, or Assumption of the
Obligations of, the Servicer or the Depositor. Any corporation into which the
Servicer or the Depositor may be merged or consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Servicer or
the Depositor shall be a party, or any corporation succeeding to the business of
the Servicer or the Depositor, shall be the successor of the Servicer or the
Depositor, as the case may be, hereunder, without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

         Section 5.03. Limitation on Liability of the Servicer and Others.
Neither the Servicer nor any of the directors or officers or employees or agents
of the Servicer shall be under any liability to the Trust or the Noteholders or
Residual Certificateholders for any action taken or for refraining from the
taking of any action by the Servicer in good faith pursuant to this Agreement,
or for errors in judgment; provided, however, that this provision shall not
protect the Servicer or any such Person against any breach of representations
and warranties made herein, or against any specific liability imposed on the
Servicer for a breach of its servicing under this Agreement or against liability
which would otherwise be imposed by reason of willful misfeasance, bad faith or
negligence in the performance of duties of the Servicer or by reason of reckless
disregard of obligations and duties of the Servicer hereunder. The Servicer and
any director or officer or employee or agent of the Servicer may rely in good

director or officer or employee or agent of the Servicer shall be indemnified by
the Trust, in accordance with the priorities set forth in Section 8.7(b) of the
Indenture and held harmless against any loss, liability or expense incurred in
connection with any legal action relating to this Agreement or the Notes, other
than any loss, liability or expense related to any specific Mortgage Loan
(except as any such loss, liability or expense shall be otherwise reimbursable
pursuant to this Agreement) and any loss, liability or expense incurred by
reason of its willful misfeasance, bad faith or negligence, breach of
representations and warranties made herein, or against any specific liability
imposed on the Servicer for a breach of its servicing under this Agreement or

disregard of obligations and duties hereunder. The Servicer shall not be under
any obligation to appear in, prosecute or defend any legal action which is not
incidental to duties to service the Mortgage Loans in accordance with this
Agreement, and which in its opinion may involve it in any expense or liability;
provided, however, that the Servicer may in its sole

                                       18
<PAGE>

discretion undertake any such action which it may deem necessary or desirable in
respect of this Agreement, and the rights and duties of the parties hereto and
the interests of the Noteholders and Residual Certificateholders hereunder. In
such event, the reasonable legal expenses and costs of such action and any
liability resulting therefrom shall be expenses, costs and liabilities of the
Trust and the Servicer shall only be entitled to be reimbursed therefor pursuant
to Section 8.7(b)(x) of the Indenture. The Servicer's right to indemnity or
reimbursement pursuant to this Section 5.03 shall survive any resignation or
termination of the Servicer pursuant to Section 5.04 or 6.01 with respect to any
losses, expenses, costs or liabilities arising prior to such resignation or
termination (or arising from events that occurred prior to such resignation or
termination).

         Section 5.04. [Reserved]

         Section 5.05. Indemnification by the Depositor and the Seller.
Notwithstanding anything to the contrary contained herein, (x) the Depositor
shall indemnify and hold harmless the Trust, the Owner Trustee and the Indenture
Trustee from and against any loss, liability, expense, damage, claim or injury
(other than those attributable to a Noteholder as a result of defaults on the
Mortgage Loans) arising out of or based on the Depositor's actions or omissions
in connection with this Agreement or the Related Documents which are not in
accordance with the provisions of this Agreement or such documents and (y) the
Depositor and the Seller, jointly and severally, shall indemnify and hold
harmless the Indenture Trustee from and against any other loss, liability,
expense, damage, claim or injury (other than those attributable to a Noteholder
as a result of defaults on the Mortgage Loans) arising out of or based on, this
Agreement or the Related Documents, including (but not limited to), in each
case, any judgment, award, settlement, reasonable attorneys' fees and expenses
and other costs or expenses incurred in connection with the defense of any
actual or threatened action, proceeding or claim; provided that the Depositor
(and, in the case of the Indenture Trustee, the Seller) shall not indemnify the
Owner Trustee or the Indenture Trustee if such loss, liability, expense, damage
or injury is due to the Owner Trustee's or the Indenture Trustee's,
respectively, willful misconduct, bad faith or negligence, material breach of
representations and warranties made herein, or against any specific liability
imposed on the Owner Trustee or Indenture Trustee for a breach of its
obligations hereunder. The provisions of this indemnity shall run directly to

<PAGE>

imposed by reason of willful misconduct, bad faith or negligence in the
performance of its duties or by reason of reckless disregard of its obligations
and duties hereunder. The Depositor and any director or officer or employee or
agent of the Depositor may rely in good faith on any document of any kind prima
facie properly executed and submitted by any Person respecting any matters
arising hereunder.

                                   ARTICLE VI

                              SERVICING TERMINATION

         Section 6.01. Events of Servicing Termination. The Events of Servicing
Termination and the rights and remedies of the parties hereto, the Insurer and
the Noteholders with respect thereto are set forth in the Master Servicing
Agreement.

         Section 6.02. Indenture Trustee to Act; Appointment of Successor.

         (a) Within 90 days of the time the Servicer receives a notice of
termination pursuant to Section 6.01 or resigns pursuant to Section 5.04, the
Indenture Trustee shall become the successor in all respects to the Servicer 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 and
shall use the same degree of care and skill as is required of the Servicer under
this Sale and Servicing Agreement; provided, however, if the Indenture Trustee
becomes the Servicer hereunder, it shall have no responsibility or obligation
(i) of repurchase or substitution with respect to any Mortgage Loan, (ii) with
respect to any representation or warranty of the Servicer, and (iii) for any act
or omission of either a predecessor or successor Servicer other than the
Indenture Trustee. As compensation therefor, the Indenture Trustee shall be
entitled to such compensation as the Servicer would have been entitled to
hereunder if no such notice of termination had been given. In addition, the
Indenture Trustee will be entitled to compensation with respect to its expenses
in connection with conversion of certain information, documents and record
keeping, as provided in Sections 6.7 and 6.8 of the Indenture. The Indenture
Trustee has been authorized and empowered pursuant to the Master Servicing
Agreement to execute and deliver, on behalf of the Servicer, as attorney-in-fact
or otherwise, any and all documents and other instruments, and to do or
accomplish all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, whether to complete the transfer and
endorsement of each Mortgage Loan and related documents, or otherwise.
Notwithstanding the above, (i) if the Indenture Trustee is unwilling to act as
successor Servicer, or (ii) if the Insurer is unwilling to have the Indenture
Trustee act as successor Servicer or (iii) if the Indenture Trustee is legally
unable so to act, the Indenture Trustee may with the consent of the Insurer,
which consent shall not be unreasonably withheld, delayed or denied (in the
situation described in clauses (i) or (ii)) or shall (in the situation described
in clause (iii)) appoint or petition a court of competent jurisdiction to
appoint, any established housing and home finance institution, bank or other
mortgage loan or home equity loan servicer with all licenses and permits
required to perform its obligations under this Agreement and having a net worth
of not less than $15,000,000 as the successor to the Servicer hereunder in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Servicer hereunder; provided that any such successor Servicer shall be
acceptable to the Insurer, as evidenced by its prior written consent, which
consent shall not be unreasonably withheld; and

                                       20
<PAGE>

provided, further, that the appointment of any such successor Servicer will not
result in the qualification, reduction or withdrawal of the ratings assigned to
the Notes by the Rating Agencies without regard to the Policy. Pending
appointment of a successor to the Servicer hereunder, unless the Indenture
Trustee is prohibited by law from so acting, the Indenture Trustee shall, within
the 90 day period specified above, act in such capacity as hereinabove provided.
In connection with such appointment and assumption, the successor shall be
entitled to receive compensation out of payments on Mortgage Loans in an amount
equal to the compensation which the Servicer would otherwise have received
pursuant to this Agreement (or such other compensation as the Indenture Trustee
and such successor shall agree). The Indenture Trustee and such successor shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

         (b) Any successor, including the Indenture Trustee, to the Servicer as
servicer shall during the term of its service as servicer (i) continue to
service and administer the Mortgage Loans for the benefit of the Noteholders,
Residual Certificateholders and the Insurer and (ii) maintain in force a policy
or policies of insurance covering errors and omissions in the performance of its
obligations as Servicer hereunder and a fidelity bond in respect of its
officers, employees and agents to the same extent as the Servicer is so required
pursuant to this Agreement. The appointment of a successor Servicer shall not
affect any liability of the predecessor Servicer which may have arisen under
this Agreement prior to its termination as Servicer (including, without
limitation, any deductible under an Insurance Policy pursuant to Section 3.04),
nor shall any successor Servicer be liable for any acts or omissions of the
predecessor Servicer or for any breach by such Servicer of any of its
representations or warranties contained herein.

         Section 6.03. Notification to Noteholders and Residual
Certificateholders. Upon the occurrence of any Event of Servicing Termination or
Rapid Amortization Event in which a Responsible Officer of the Indenture Trustee
has actual notice (or any event that with the lapse of time would become an
Event of Servicing Termination or Rapid Amortization Event unless cured), the
Indenture Trustee shall promptly notify the Owner Trustee in writing. Upon any
termination or appointment of a successor to the Servicer pursuant to this
Article VI or Section 5.04, the Indenture Trustee shall give prompt written
notice thereof to the Noteholders, Residual Certificateholders (at their
respective addresses appearing in the Note Register and in the Residual
Certificate Register), the Insurer and each Rating Agency.

                                   ARTICLE VII

                                   TERMINATION

         Section 7.01. Termination; Redemption of Notes.

         (a) The respective obligations and responsibilities of the Servicer,
the Seller, the Depositor and the Indenture Trustee created hereby (other than
the obligation of the Indenture Trustee to make certain payments to Noteholders
and Residual Certificateholders after the final Payment Date and the obligation
of the Servicer to send certain notices as hereinafter set forth) shall
terminate upon the last action required to be taken by the Indenture Trustee on
the final Payment Date pursuant to this Article VII following the later of (A)
the Payment Date following

                                       21
<PAGE>

payment in full of all amounts owing to the Insurer under the Insurance
Agreement and (B) the earliest of (i) the transfer, under the conditions
specified in Section 7.01(b), (ii) the day following the Payment Date on which
the distribution made to Noteholders has reduced the Note Principal Balance to
zero and no other amounts are owed to the Noteholders hereunder, and no other
amounts are owed to the Insurer pursuant to the Insurance Agreement and Section
8.7 of the Indenture, (iii) the final payment or other liquidation of the last
Mortgage Loan remaining in the Trust (including, without limitation, the
disposition of the Mortgage Loans pursuant to Section 5.4 of the Indenture) or
the disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (iv) the Payment Date in December 2014;
provided, however, that in no event shall the trust created hereby continue
beyond the expiration of 21 years from the date of death of the last surviving
descendants of Joseph P. Kennedy, the late ambassador of the United States to
the Court of St. James, living on the date hereof. Upon termination in
accordance with clause (a)(B)(i) of this Section 7.01, the Indenture Trustee, on
behalf of the Trust, shall execute such documents and instruments of transfer
presented by the Optional Redemption Holder, in each case without recourse,
representation or warranty, and take such other actions as the Optional
Redemption Holder may reasonably request to effect the transfer of the Mortgage
Loans to the Optional Redemption Holder.

         (b) Subject to Section 7.01(d), (x) the Holder of the Class C Interest
shall have the right to cause the Issuer to redeem the Notes on any Payment Date
occurring on or after the end of a Collection Period on which the Note Principal
Balance on such Payment Date is less than or equal to twenty percent (20%) of
the Original Note Principal Balance and (y) the holder of the majority interest
in the Class O Certificates shall have the right to redeem the Notes on any
Payment Date occurring on or after the end of a Collection Period on which the
Note Principal Balance on such Payment Date is less than or equal to ten percent
(10%) of the Original Note Principal Balance. In the case of clause (x) above,
the Optional Redemption Holder may purchase the Trust Property and cause the
termination of this Agreement and the Indenture pursuant to this Section 7.01
and Section 10.1 of the Indenture, or may purchase the Notes at the Redemption
Price without purchasing the Trust Property as set forth in Section 10.1 of the
Indenture. In the case of clause (y) above, the Optional Redemption Holder may
only purchase the Trust Property and may not otherwise repurchase the Notes. If
the Optional Redemption Holder elects to exercise its right it will notify the
Issuer, the Servicer, the Indenture Trustee and the Insurer no later than
thirty-five (35) days prior to the Payment Date on which the transfer is to take
place. The Indenture Trustee, on behalf of the Trust, will make the transfer of
the Mortgage Loans on such Payment Date (unless the Optional Redemption Holder
will cause the repurchase of the Notes and will not purchase the Mortgage Loans
as set forth above) subject to Section 7.01(d) and provided that the Redemption
Price for the Notes has been deposited with it on or prior to such Payment Date.

         (c) The Optional Redemption Holder, at its expense, shall prepare and
deliver to the Indenture Trustee, on behalf of the Trust, for execution, at the
time the related Mortgage Loans are to be released to the Optional Redemption
Holder, appropriate documents assigning each such Mortgage Loan from the
Indenture Trustee to the Optional Redemption Holder and shall promptly record
such assignments.

         (d) The Optional Redemption Holder shall not exercise its right under
Section 7.01(b) hereof if (a) such optional redemption would result in a draw on
the Policy, without the consent

                                       22
<PAGE>

of the Insurer, and (b) any Reimbursement Amount due to the Insurer would not be
fully satisfied pursuant to the optional redemption.

         (e) In the event that the holder of the Class C Interest exercises its
right as Optional Redemption Holder to repurchase the Notes without the purchase
of the Trust Property as specified above, prior to any transfer or pledge of the
Notes by such holder to a Person that is not its Affiliate, such holder shall
provide the Indenture Trustee and the Issuer an Opinion of Counsel, which shall
not be an expense of the Issuer, stating that such transfer or pledge will not
(a) result in the Trust being subject to tax at the entity level for federal and
applicable state tax purposes or (b) result in the arrangement created by the
Trust Agreement or any "portion" of the Trust being treated as a taxable
mortgage pool as defined in Section 7701(I) of the Code.

provided in the Basic Documents to be performed by another party, the Depositor
shall prepare for execution by the Issuer or shall cause the preparation by
other appropriate Persons of all such documents, reports, filings, instruments,
certificates and opinions as it shall be the duty of the Issuer to prepare, file
or deliver pursuant to the Indenture and perform such other tasks set forth in
the Indenture that are the duty of the Issuer and are not expressly provided in
the Basic Documents to be performed by another party. In furtherance of the
foregoing, the Depositor shall take all necessary action that is the duty of the

         (b) Duties with Respect to the Issuer.

                  (i) Except as otherwise expressly provided in the Basic
         Documents to be performed by another party, in addition to the duties
         of the Depositor set forth in this Agreement or any of the Basic
         Documents, the Depositor shall perform such calculations and shall
         prepare for execution by the Issuer or the Owner Trustee or shall cause
         the preparation by other appropriate Persons of all such documents,
         reports, filings, instruments, certificates and opinions as it shall be
         the duty of the Issuer or the Owner Trustee to prepare, file or deliver
         pursuant to this Agreement or any of the Basic Documents or under state
         and federal tax and securities laws, and at the request of the Owner
         Trustee shall take all appropriate action that it is the duty of the
         Issuer to take pursuant to this Agreement or any of the Basic
         Documents. In accordance with the directions of the Issuer or the Owner
         Trustee, the Depositor shall administer, perform or supervise the
         performance of such other activities in connection with the Mortgage
         Loans (including the Basic Documents) as are not covered by any of the
         foregoing provisions and as are expressly requested by the Issuer or
         the Owner Trustee and are reasonably within the capability of the
         Depositor.

                  (ii) Notwithstanding anything in this Agreement or any of the
         Basic Documents to the contrary, the Depositor shall be responsible for
         promptly notifying the

                                       23
<PAGE>

         Owner Trustee and the Indenture Trustee and the Insurer in the event
         that any withholding tax is imposed on the Issuer's payments (or
         allocations of income) to a Residual Certificateholder (as defined in
         the Trust Agreement) as contemplated by this Agreement. Any such notice
         shall be in writing and specify the amount of any withholding tax
         required to be withheld by the Owner Trustee or the Indenture Trustee
         pursuant to such provision.

                  (iii) Notwithstanding anything in this Agreement or the Basic
         Documents to the contrary, the Depositor shall not be responsible for
         performance of the duties of the Issuer or the Indenture Trustee set
         forth in Section 6.1(a), (b), (c) and (d) of the Trust Agreement with
         respect to, among other things, accounting and reports to Residual
         Certificateholders (as defined in the Trust Agreement).

                  (iv) In carrying out the foregoing duties or any of its other
         obligations under this Agreement, the Depositor may enter into
         transactions with or otherwise deal with any of its Affiliates;
         provided, however, that the terms of any such transactions or dealings
         shall be in accordance with any directions received from the Issuer and
         shall be, in the Servicer's opinion, no less favorable to the Issuer in
         any material respect.

         (c) Non-Ministerial Matters. With respect to matters that in the
reasonable judgment of the Depositor are non-ministerial, the Depositor shall
not take any action pursuant to this Article VIII unless within a reasonable
time before the taking of such action, the Depositor shall have notified the
Owner Trustee and the Insurer of the proposed action and the Owner Trustee and
the Insurer shall not have withheld consent or provided an alternative
direction. For the purpose of the preceding sentence, "non-ministerial matters"
shall include:

                  (A) the amendment of or any supplement to the Indenture;

                  (B) the initiation of any claim or lawsuit by the Issuer and
         the compromise of any action, claim or lawsuit brought by or against
         the Issuer (other than in connection with the collection of the
         Mortgage Loans);

                  (C) the amendment, change or modification of this Agreement or

         of its obligations under the Indenture; and

                  (E) the removal of the Indenture Trustee.

         (d) Exceptions. Notwithstanding anything to the contrary in this
Agreement, except as expressly provided herein or in the other Basic Documents,
the Depositor, in its capacity hereunder, shall not be obligated to, and shall
not, (1) make any payments to the Noteholders or the Residual Certificateholders
under the Basic Documents, (2) sell the Trust Property pursuant to Section 5.4
of the Indenture, (3) take any other action that the Issuer directs the
Depositor not

                                       24
<PAGE>

to take on its behalf or (4) in connection with its duties hereunder assume any
indemnification obligation of any other Person.

         Section 8.02. Records. The Servicer and the Depositor shall maintain
appropriate books of account and records relating to services performed under
this Agreement, which books of account and records shall be accessible for
inspection by the Issuer, the Insurer and the Indenture Trustee at any time
during normal business hours.

         Section 8.03. Additional Information to be Furnished to the Issuer. The
Servicer and the Depositor shall furnish to the Issuer and the Indenture Trustee
from time to time such additional information regarding the Mortgage Loans as
the Issuer and the Indenture Trustee shall reasonably request.

                                   ARTICLE IX

                            MISCELLANEOUS PROVISIONS

         Section 9.01. Amendment.

         The Master Servicing Agreement, as incorporated by reference herein,
may be amended by agreement of all of the Servicer, the Depositor and the
Indenture Trustee, with the consent of the Insurer but without the consent of
the Noteholders; provided a letter is obtained from the Rating Agencies stating
that such amendment would not result in a downgrading or withdrawal of the then
current rating of the Notes, without regard to the Policy.

         This Agreement may also be amended from time to time by agreement of
all of the Depositor, the Servicer, the Seller and the Indenture Trustee, in
each case without notice to or the consent of any of the Noteholders or Residual
Certificateholders, but only with the consent of the Insurer (which consent
shall not be unreasonably withheld, delayed or denied), (i) to cure any
ambiguity, (ii) to correct any defective provisions or to correct or supplement
any provisions herein that may be inconsistent with any other provisions herein
or with any Offering Document, (iii) to add to the duties of the Depositor or
the Servicer, (iv) to add any other provisions with respect to matters or
questions arising under this Agreement or the Policy, as the case may be, which
shall not be inconsistent with the provisions of this Agreement, (v) to add or
amend any provisions of this Agreement as required by any Rating Agency or any
other nationally recognized statistical rating organization in order to maintain
or improve any rating of the Notes (it being understood that, after obtaining
the ratings in effect on the Closing Date, neither the Indenture Trustee, the
Depositor nor the Servicer is obligated to obtain, maintain or improve any such
rating) or (vi) to comply with any requirement imposed by the Code; provided,
however, that such action shall not, as evidenced by an Opinion of Counsel,
materially and adversely affect the interests of any Noteholder, any Residual
Certificateholder, or the Insurer; and provided, further, that the amendment
shall be deemed not to adversely affect in any material respect the interests of
the Noteholders and the Residual Certificateholders and no opinion referred to
in the preceding proviso shall be required to be delivered if the consent of the
Class O Certificateholders and a letter from each Rating Agency stating that the
amendment would not result in the downgrading or withdrawal of the respective
ratings then assigned to the Notes without regard to the Policy are obtained.

                                       25
<PAGE>

         This Agreement also may be amended from time to time by agreement of
all of the Servicer, the Seller, the Depositor and the Indenture Trustee, with
the consent of the Insurer and the Holders of the Notes evidencing more than 50%
of the Outstanding Amount of the Notes and the Residual Certificateholders
evidencing more than 50% of the percentage interest in each class of Residual
Certificates (which consent of such Noteholders and Residual Certificateholders
given pursuant to this Section 9.01 or pursuant to any other provision of this
Agreement shall be conclusive and binding on such holders and all future holders
of such securities and of any security issued upon the transfer thereof or in
exchange thereof or in lieu thereof whether or not notation of such consent is
made upon the security) 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 Noteholders or the Residual
Certificateholders; provided, however, that no such amendment shall (i) reduce
in any manner the amount of, or delay the timing of, payments on the Notes or
the Residual Certificates or distributions or payments under the Policy which
are required to be made on any Note without the consent of the Holder of such
Note or the related Certificateholder, as applicable, or (ii) reduce the
aforesaid percentage required to consent to any such amendment, without the
consent of the holders of all then outstanding Notes and Residual Certificates
or (iii) adversely affect in any material respect the interests of the Insurer.

         Following the execution and delivery of any such amendment hereto or to
the Policy, either the Depositor, if the Depositor requested the amendment, or
the Servicer, if the Servicer requested the amendment, shall reimburse the
Insurer for the reasonable out-of-pocket costs and expenses incurred by each in
connection with such amendment.

         Prior to the execution of any such amendment, the party hereto
requesting any such amendment shall furnish written notification of the
substance of such amendment to each Rating Agency. In addition, promptly after
the execution of any such amendment made with the consent of the Noteholders or
the Residual Certificateholders, the Indenture Trustee shall furnish written
notification of the substance of such amendment to each Noteholder and Residual
Certificateholder and fully executed original counterparts of the instruments
effecting such amendment to the Insurer.

         It shall not be necessary for the consent of Noteholders or Residual
Certificateholders under this Section 9.01 to approve the particular form of any
proposed amendment or consent, but it shall be sufficient if such consent shall
approve the substance thereof. The manner of obtaining such consents and of
evidencing the authorization of the execution thereof by Noteholders and
Residual Certificateholders shall be subject to such reasonable requirements as
the Indenture Trustee may prescribe.

         In executing any amendment permitted by this Section 9.01, the
Indenture Trustee and the Issuer shall be entitled to receive, and shall be
fully protected in relying upon, an Opinion of Counsel stating that such
amendment is authorized or permitted hereby and that all conditions precedent to
the execution and delivery of such amendment have been satisfied. The Indenture
Trustee may, but shall not be obligated to, enter into any such amendment which
affects the Indenture Trustee's own rights, duties or immunities under this
Agreement or otherwise.

                                       26

         Section 9.02. Recordation of Agreement. This Agreement is subject to
recordation in all appropriate public offices for real property records in all
the counties or other comparable jurisdictions in which any or all of the
properties subject to the Mortgages are situated, and in any other appropriate
public recording office or elsewhere, such recordation to be effected by the
Servicer, but only upon direction of Noteholders accompanied by an Opinion of
Counsel to the effect that such recordation materially and beneficially affects
the interests of Noteholders. The Noteholders requesting such recordation shall
bear all costs and expenses of such recordation. The Indenture Trustee shall
have no obligation to ascertain whether such recordation so affects the
interests of the Noteholders.

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

         Section 9.03. Limitation on Rights of Noteholders. No Noteholder shall
have any right to vote (except as provided in Sections 6.01, 7.01, and 9.01
herein and Section 5.4 of the Indenture) or in any manner otherwise control the
operation and management of the Trust, or the obligations of the parties hereto,
nor shall anything herein set forth, or contained in the terms of the Notes, be
construed so as to constitute the Noteholders from time to time as partners or
members of an association; nor shall any Noteholder be under any liability to
any third person by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

         No Noteholder shall have any right by virtue or by availing itself of
any provisions of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Indenture Trustee a written notice of
default and of the continuance thereof, as hereinbefore provided, and unless
also the Holders of Notes evidencing more than 50% of the Outstanding Amount of
the Notes shall have made written request upon the Indenture Trustee to
institute such action, suit or proceeding in its own name as Indenture Trustee
hereunder and shall have offered to the Indenture Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Indenture Trustee, for 60 days after its
receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding; it being understood
and intended, and being expressly covenanted by each Noteholder with every other
Noteholder and the Indenture Trustee, that no one or more Holders of Notes shall
have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Notes, or to obtain or seek to
obtain priority over or preference to any other such Holder, or to enforce any
right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Noteholders. For the protection and
enforcement of the provisions of this Section 9.03, each and every Noteholder
and the Indenture Trustee shall be entitled to such relief as can be given
either at law or in equity.

         Anything to the contrary notwithstanding, by accepting its Note, each
Noteholder agrees that unless a Insurer Default exists, the Insurer shall have
the right to exercise all rights of the Noteholder under this Agreement without
any further consent of the Noteholder.
