("NAFI", and in its capacity as Servicer, the "Servicer").

                             INTRODUCTORY STATEMENTS

                  A. On the Closing Date, (i) the Master Trust will sell all of
         its right, title and interest in and to the Receivables and certain

         II will simultaneously sell all of its right, title and interest in and
         to the Receivables and such other property related thereto to the

         of the principal of and interest on the Securities (including any such
         distributions subsequently avoided as a preference under applicable

         and servicing agreements, indentures, receivables purchase agreements
         or other financing documents (each, a "Securitization Agreement")
         pursuant to which NAFI, Funding Trust II, the Transferor and/or such
         other Affiliate of NAFI has sold, pledged or otherwise transferred, and
         will sell, pledge or otherwise transfer, all or a portion of its right,
         title and interest in and to pools of contracts and/or other financial
         assets or property to a trust or other Person and in connection
         therewith Financial Security in its discretion has issued policies, and
         may in the future issue additional policies, with respect to certain
         guaranteed distributions or scheduled payments with respect to the
         corresponding securities, certificates, notes or other obligations
         issued or arising under such Securitization Agreements.

contained, Financial Security, the Trust, the Transferor and NAFI hereby agree
as follows:

                                   ARTICLE I.

                                   DEFINITIONS

         Section 1.01. Definitions. Capitalized terms used herein shall have the
meanings provided in Appendix I hereto unless the context otherwise requires.
Unless otherwise defined in this Insurance Agreement, all terms defined in the
Sale and Servicing Agreement or in the Spread Account Agreement shall have the
same meanings in this Insurance Agreement. Unless otherwise specified, if a word
or phrase defined in the Sale and Servicing Agreement or in the Spread Account
Agreement can be applied with respect to one or more Series, such a word or
phrase shall be used herein as applied to Series 1999-1.

                                  ARTICLE II.

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

         Section 2.01. Representations and Warranties of the Trust. The Trust
represents, warrants and covenants, as of the date hereof and as of the Date of
Issuance, with respect to itself and otherwise as follows:

                  (a) Due Organization and Qualification. The Trust is a
         Delaware statutory business trust, duly formed, validly existing and in
         good standing under the laws of the State of Delaware, with power and
         authority to own its properties and to conduct its business. The Trust
         is duly qualified to do business, is in good standing and has obtained
         all necessary licenses, permits, charters, registrations and approvals
         (together, "approvals") necessary for the conduct of its business as
         currently conducted and as described in the Offering Document and the
         performance of its obligations under the Transaction Documents, in each
         jurisdiction in which the failure to be so qualified or to obtain such
         approvals would render any Receivable unenforceable in any respect or
         would otherwise have a material adverse effect upon the Transaction.

                  (b) Power and Authority. The Trust has all necessary trust
         power and authority to conduct its business as currently conducted and
         as described in the Offering Document, to execute, deliver and perform
         its obligations under the Transaction Documents and to consummate the
         Transaction.

                                       2

<PAGE>   6

                  (c) Due Authorization. The execution, delivery and performance
         of the Transaction Documents by the Trust have been duly authorized by
         all necessary action on the part of the Trust and do not require any
         additional approvals or consents or other action by or any notice to or
         filing with any Person by or on behalf of the Trust, including, without
         limitation, any governmental entity.

                  (d) Noncontravention. None of the execution and delivery of
         the Transaction Documents by the Trust, the consummation of the
         transactions contemplated thereby or the satisfaction of the terms and
         conditions of the Transaction Documents,

                           (i) conflicts with or results in any breach or
         violation of any provision of the certificate of trust of the Trust or
         the Trust Agreement, or any law, rule, regulation, order, writ,
         judgment, injunction, decree, determination or award currently in
         effect having applicability to the Trust, or any of its properties,
         including regulations issued by an administrative agency or other
         governmental authority having supervisory powers over the Trust,

                           (ii) constitutes or will constitute a default by the
         Trust under or a breach of any provision of any loan agreement,
         mortgage, indenture or other agreement or instrument to which the Trust
         is a party or by which it or any of its properties may be bound or
         affected, or

                           (iii) results in or requires the creation of any Lien
         upon or in respect of any of the assets of the Trust except as
         otherwise expressly contemplated by the Transaction Documents.

                  (e) Legal Proceedings. There is no action, proceeding or
         investigation, by or before any court, governmental or administrative
         agency or arbitrator against or affecting all or any of the
         Receivables, the Trust, or any properties or rights of the Trust,
         pending or threatened, which, in any case, if decided adversely, could
         result in a Material Adverse Change with respect to the Trust or any
         Receivable.

                  (f) Valid and Binding Obligations. Each of the Transaction
         Documents to which the Trust is a party when executed and delivered by
         the Owner Trustee on behalf of the Trust, will constitute the legal,
         valid and binding obligations of the Trust, enforceable in accordance
         with its respective terms, except as such enforceability may be limited
         by bankruptcy, insolvency, reorganization, moratorium or other similar
         laws affecting creditors' rights generally and general equitable
         principles. The Securities and the Class B Notes; when executed,
         authenticated and delivered in accordance with the Indenture, will be
         entitled to the benefits of the Indenture and will constitute legal,
         valid and binding obligations of the Trust, enforceable in accordance
         with their terms. The Certificate, when executed, authenticated and
         delivered in accordance with the Trust Agreement, will be validly
         issued and outstanding and entitled to the

                                       3
<PAGE>   7

         benefits of the Trust Agreement and will evidence the entire beneficial
         interest in the Trust.

                  (g) ERISA. The Trust does not maintain or contribute to, or
         have any obligation to maintain or contribute to, any Plan. The Trust
         has no duties under ERISA.

                  (h) Accuracy of Information. None of the Provided Documents
         contain any statement of a material fact with respect to the Trust or
         the Transaction that was untrue or misleading in any material respect
         when made. Since the furnishing of the Provided Documents, there has
         been no change, nor any development or event involving a prospective
         change known to the Trust that would render any of the Provided
         Documents untrue or misleading in any material respect. There is no
         fact known to the Trust which has a material possibility of causing a
         Material Adverse Change with respect to the Trust or the Receivables.

                  (i) Compliance With Securities Laws. The offer and sale of the
         Securities, the Class B Notes and the issuance of the Certificate,
         comply in all material respects with all requirements of law, including
         all applicable registration requirements of securities laws. Without
         limitation of the foregoing, the Offering Document does not contain any
         untrue statement of a material fact and does not omit to state a
         material fact required to be stated therein or necessary to make the
         statements made therein, in light of the circumstances under which they
         were made, not misleading; provided that no representation is made with
         respect to information included in an Offering Document and furnished
         by Financial Security in writing expressly for use therein (all such
         information so furnished being referred to herein as "Financial
         Security Information"), it being understood that, in respect of the
         Offering Document, the Financial Security Information is limited to the
         information included under the caption "THE NOTE INSURER", and the
         financial statements of Financial Security attached thereto as Exhibit
         [ ]. None of the Trust Agreement, the Indenture or the Sale and
         Servicing Agreement is required to be qualified under the Trust
         Indenture Act.

                  (j) Incorporation of Certain Representations and Warranties.
         Each of the representations and warranties of the Trust contained in
         the Transaction Documents is true and correct in all material respects
         and the Trust hereby makes each such representation and warranty made
         by it to, and for the benefit of, Financial Security as if the same
         were set forth in full herein.

                  (k) No Consents. No consent, license, approval or
         authorization from, or registration, filing or declaration with, any
         regulatory body, administrative agency, or other governmental
         instrumentality, nor any consent, approval, waiver or notification of
         any creditor, lessor or other nongovernmental Person, is required with
         respect to, or to be obtained by, the Trust in connection with the
         execution, delivery and performance by the Trust of this Insurance
         Agreement or

                                       4
<PAGE>   8

         any other Transaction Document to which the Trust is a party, except
         (in each case) such as have been obtained and are in full force and
         effect.

                  (l) Compliance With Law, Etc. No practice, procedure or policy
         employed or proposed to be employed by the Trust in the conduct of its
         business violates any law, regulation, judgment, agreement, order or
         decree applicable to it which, if enforced, would result in a Material
         Adverse Change with respect to the Trust.

                  (m) Special Purpose Entity.

                           (i) The capital of the Trust is adequate for the
         business and undertakings of the Trust.

                           (ii) Other than the transactions as provided in the
         Transaction Documents, the Trust is not engaged in any business
         transactions with NAFI, the Transferor or any of their respective
         Subsidiaries or Affiliates.

                           (iii) The Trust's funds and assets are not, and will
         not be, commingled with the funds of any other Person.

                  (n) Solvency; Fraudulent Conveyance. The Trust is solvent and
         will not be rendered insolvent by the Transaction and, after giving
         effect to such Transaction, the Trust will not be left with an
         unreasonably small amount of capital with which to engage in its
         business. The Trust does not intend to incur, or believe that it has
         incurred, debts beyond its ability to pay such debts as they mature.
         The Trust does not contemplate the commencement of insolvency,
         bankruptcy, liquidation or consolidation proceedings or the appointment
         of a receiver, liquidator, conservator, trustee or similar official in
         respect of the Trust or any of its assets. The Trust is not pledging
         the Collateral to the Trust Collateral Agent, or issuing the
         Securities, the Class B Notes and the Certificate, as provided in the
         Transaction Documents, with any intent to hinder, delay or defraud any
         of the Trust's creditors.

                  (o) Investment Company Act Compliance. Neither the Trust nor
         the Owner Trust Estate is required to be registered as an "investment
         company" under the Investment Company Act. The Trust is not subject to
         the information reporting requirements of the Securities Exchange Act.

                  (p) Collateral. On the Date of Issuance, the Trust will be the
         owner of, and will have good and marketable title to, each item of
         Other Trust Property conveyed on such date and will own each such item
         free and clear of all Liens and Restrictions on Transferability (other
         than Liens contemplated under the Indenture) or any equity or
         participation interest of any other Person and will have full right,
         power and lawful authority to pledge such Other Trust Property pursuant
         to the Indenture. The Indenture constitutes a valid pledge of the

                                       5
<PAGE>   9

         Collateral to the Trust Collateral Agent, and the Trust Collateral
         Agent shall have a valid and perfected first priority security interest
         in the Collateral, free and clear of all Liens and Restrictions on
         Transferability.

                  (q) Perfection of Liens and Security Interest. On the Closing
         Date, the Lien and security interest in favor of the Trust Collateral
         Agent with respect to the Collateral will be perfected by the delivery
         of the Receivable Files to the Custodian, which Receivable Files the
         Custodian will hold on behalf of the Trust Collateral Agent, the filing
         of financing statements on Form UCC-1 in each jurisdiction where such
         recording or filing is necessary for the perfection of such Lien and
         security interest, and the establishment of the Collection Account, the
         Distribution Account, the Class A Note Distribution Account and the
         Class B Note Distribution Account in accordance with the provisions of

         the following statement immediately preceding such financial
         statements:

                  The New York State Insurance Department recognizes only
                  statutory accounting practices for determining and reporting
                  the financial condition and results of operations of an
                  insurance company, for determining its solvency under the New
                  York Insurance Law, and for determining whether its financial
                  condition warrants the payment of a dividend to its
                  stockholders. No consideration is given by the New York State
                  Insurance Department to financial statements prepared in
                  accordance with generally accepted accounting principles in
                  making such determinations.

         (2) Each Offering Document subsequent to the Date of Issuance shall be
in form and substance satisfactory to Financial Security in its sole discretion
as evidenced by Financial Security's prior written consent to the use thereof.

                  (k) Special Purpose Entity.

                           (i) The Trust shall conduct its business solely in
         its own name through its duly authorized officers or agents so as not
         to mislead others as to the identity of the entity with which those
         officers are concerned, and particularly will avoid the appearance of
         conducting business on behalf of NAFI, the Transferor or any of their
         respective Affiliates or that the assets of the Trust are available to
         pay the creditors of NAFI, the Transferor or any of their respective
         Affiliates. Without limiting the generality of the foregoing, all oral
         and written communications, including, without limitation, letters,
         invoices, purchase orders, contracts, statements and loan applications,
         will be made solely in the name of the Trust.

         hereto in writing with respect to such address.

         from its equity owners of all trust action requiring such
         authorization, and copies of each such authorization and the minutes or
         other written summary of each such meeting shall be delivered to
         Financial Security within two weeks of such authorization or meeting,
         as the case may be.

                           (iv) Although the organizational expenses of the
         Trust have been paid by the Seller, operating expenses and liabilities
         of the Trust shall be paid from its own funds.

                           (v) The annual financial statements of the Trust
         shall disclose the effects of the Trust's transactions in accordance
         with generally accepted accounting principles and shall disclose that

         relationship with NAFI, the Transferor and their respective Affiliates
         and will not hold itself out as being liable for the debts of NAFI, the
         Transferor or any of their respective Affiliates.

                           (viii) The Trust shall keep its assets and its
         liabilities wholly separate from those of all other entities,
         including, but not limited to NAFI, the Transferor and their respective
         Affiliates.

                  (l) Maintenance of Licenses. The Trust shall maintain all
         licenses, permits, charters and registrations which are material to the
         performance by the Trust of its business and of its obligations under

         proceeding or other action (A) under any existing or future law of any

and the Transferor represents, warrants and covenants, as of the date hereof and
the Date of Issuance with respect to itself and otherwise, as follows:

                  (a) Due Organization and Qualification. NAFI is a corporation,
         duly organized, validly existing and in good standing under the laws of
         the State of Delaware. The Transferor is a Delaware statutory business
         trust, duly formed, validly existing and in good standing under the
         laws of the State of Delaware. Each of NAFI and the Transferor is duly
         qualified to do business, is in good standing and has obtained all
         necessary licenses, permits, charters, registrations and approvals
         (together, "approvals") necessary for the conduct of its business as
         currently conducted and as described in the Offering Document and the
         performance of its obligations under the Transaction Documents, in each
         jurisdiction in which the failure to be so qualified or to obtain such
         approvals would render any Receivable unenforceable in any respect or
         would otherwise have a material adverse effect upon the Transaction.

                  (b) Power and Authority. Each of NAFI and the Transferor has
         all necessary power and authority (corporate and otherwise) to conduct
         its business as currently conducted and as described in the Offering
         Document, to execute, deliver and perform its obligations under the
         Transaction Documents and to consummate the Transaction.

                  (c) Due Authorization. The execution, delivery and performance
         of the Transaction Documents by each of NAFI and the Transferor have
         been duly authorized by all necessary action (corporate and otherwise)
         and do not require any additional approvals or consents or other action
         (corporate or otherwise) by or any notice to or filing with any Person.

<PAGE>   18

                  (d) Noncontravention. None of the execution and delivery of
         the Transaction Documents by the Transferor or NAFI, the consummation
         of the transactions contemplated thereby or the satisfaction of the
         terms and conditions of the Transaction Documents,

                           (i) conflicts with or results in any breach or
         violation of any provision of the certificate of trust and the trust
         agreement of the Transferor or the certificate of incorporation and
         by-laws of NAFI, or any law, rule, regulation, order, writ, judgment,
         injunction, decree, determination or award currently in effect having
         applicability to the Transferor or NAFI, as the case may be, or any of
         their respective properties, including regulations issued by an
         administrative agency or other governmental authority having
         supervisory powers over the Transferor or NAFI, as the case may be,

                           (ii) constitutes a default by the Transferor or NAFI,
         as the case may be, under or a breach of any provision of any loan
         agreement, mortgage, indenture or other agreement or instrument to
         which the Transferor or NAFI, as the case may be, or any of their
         respective Subsidiaries or Affiliates is a party or by which it or any
         of its or their properties is or may be bound or affected, or

                           (iii) results in or requires the creation of any Lien
         upon or in respect of any of the assets of the Transferor or NAFI or
         any of their respective Subsidiaries or Affiliates except as otherwise
         expressly contemplated by the Transaction Documents.

                  (e) Legal Proceedings. Except as set forth in the Sale and
         Servicing Agreement and in any schedule thereto, there is no action,
         proceeding or investigation by or before any court, governmental or
         administrative agency or arbitrator against or affecting all or any of
         the Receivables, NAFI, the Transferor or any of their respective
         Subsidiaries or Affiliates, or any properties or rights of NAFI, the
         Transferor or any of their respective Subsidiaries or Affiliates,
         pending or threatened, which, in any case, if decided adversely, could
         reasonably be expected to result in a Material Adverse Change with
         respect to NAFI, the Transferor or any Receivable.

                  (f) Valid and Binding Obligations. Each of the Transaction
         Documents to which either NAFI or the Transferor is a party when
         executed and delivered by NAFI or by the Transferor, as the case may
         be, will constitute the legal, valid and binding obligations of such
         Person, enforceable in accordance with their respective terms, except
         as such enforceability may be limited by bankruptcy, insolvency,
         reorganization, moratorium or other similar laws affecting creditors'
         rights generally and general equitable principles. The Securities and
         the Class B Notes, when executed, authenticated and delivered in
         accordance with the Indenture, will be binding obligations of the
         Trust, enforceable in accordance with their terms, validly issued and
         outstanding and entitled to the benefits of the Indenture, except as
         such enforceability may be limited by bankruptcy,

                                       15

<PAGE>   19

         insolvency, reorganization, moratorium or other similar laws affecting
         creditors' rights generally and general equitable principles. The
         Certificate, when executed, authenticated and delivered in accordance
         with the Trust Agreement, will be validly issued and outstanding and
         entitled to the benefits of the Trust Agreement and will evidence the
         entire beneficial ownership interest in the Trust.

                  (g) Financial Statements. The Financial Statements of each of
         the Transferor and NAFI, copies of which have been furnished to
         Financial Security, (i) are, as of the dates and for the periods
         referred to therein, complete and correct in all material respects,
         (ii) present fairly the financial condition and results of operations
         of each of the Transferor and NAFI as of the dates and for the periods
         indicated and (iii) have been prepared in accordance with generally
         accepted accounting principles consistently applied, except as noted
         therein (subject as to interim statements to normal year-end
         adjustments). Since the date of the most recent Financial Statements,
         there has been no material adverse change in such financial condition
         or results of operations. Except as disclosed in the Financial
         Statements, neither the Transferor nor NAFI is subject to any
         contingent liabilities or commitments that, individually or in the
         aggregate, have a material possibility of causing a Material Adverse
         Change in respect of the Transferor or NAFI, as the case may be.

                  (h) ERISA. Each of the Transferor and NAFI is in compliance
         with ERISA and has not incurred and does not reasonably expect to incur
         any liabilities to the PBGC under ERISA in connection with any Plan or
         Multiemployer Plan or to contribute now or in the future in respect of
         any Plan or Multiemployer Plan.

                  (i) Accuracy of Information. None of the Provided Documents
         contain any statement of a material fact with respect to NAFI, the
         Transferor or the Transaction that was untrue or misleading in any
         material respect when made. Since the furnishing of the Provided
         Documents, there has been no change, nor any development or event
         involving a prospective change known to NAFI or to the Transferor, that
         would render any of the Provided Documents untrue or misleading in any
         material respect. There is no fact known to NAFI or to the Transferor
         which has a material possibility of causing a Material Adverse Change
         with respect to NAFI, the Transferor or the Receivables.

                  (j) Compliance With Securities Laws. The offer and sale of the
         Securities and the Class B Notes, and the issuance of the Certificate,
         comply in all material respects with all requirements of law, including
         all applicable registration requirements of securities laws. Without
         limitation of the foregoing, the Offering Document does not contain any
         untrue statement of a material fact and does not omit to state a
         material fact required to be stated therein or necessary to make the
         statements made therein, in light of the circumstances under which they
         were made, not misleading; provided that no representation is made with
         respect to information included in an Offering Document and furnished
         by Financial

                                       16

         Security in writing expressly for use therein (all such information so
         furnished being referred to herein as "Financial Security
         Information"), it being understood that, in respect of the Offering
         Document, the Financial Security Information is limited to the
         information included under the caption "THE NOTE INSURER" and the
         financial statements of Financial Security attached thereto as Exhibit
         [ ]. Neither the Trust nor the Owner Trust Estate is required to be
         registered as an "investment company" under the Investment Company Act.
         None of the Trust Agreement, the Indenture or the Sale and Servicing
         Agreement is required to be qualified under the Trust Indenture Act.

                  (k) Incorporation of Certain Representations and Warranties.
         Each of the representations and warranties of NAFI and of the
         Transferor contained in the Transaction Documents is true and correct
         in all material respects and each of NAFI and the Transferor hereby
         makes each such representation and warranty made by it to, and for the
         benefit of, Financial Security as if the same were set forth in full
         herein.

                  (l) No Consents. No consent, license, approval or
         authorization from, or registration, filing or declaration with, any
         regulatory body, administrative agency, or other governmental
         instrumentality, nor any consent, approval, waiver or notification of
         any creditor, lessor or other nongovernmental Person, is required in
         connection with the execution, delivery and performance by NAFI or by
         the Transferor of this Insurance Agreement or of any other Transaction
         Document to which such Person is a party, except (in each case) such as
         have been obtained and are in full force and effect.

                  (m) Compliance With Law, Etc. No practice, procedure or policy
         employed or proposed to be employed by NAFI or by the Transferor in the
         conduct of their respective businesses violates any law, regulation,
         judgment, agreement, order or decree applicable to it which, if
         enforced, would result in a Material Adverse Change with respect to
         such Person or the Receivables.

                  (n) Special Purpose Entity.

                           (i) The capital of the Transferor is adequate for the
         business and undertakings of the Transferor.

                           (ii) Other than with respect to the ownership by NAFI
         and its Affiliates of all of the beneficial ownership interests of the
         Transferor and the transactions as provided in (A) the Transaction
         Documents and (B) the corresponding applicable agreements relating to
         the issuance by each of National Auto Finance 1995-1 Trust, National
         Auto Finance 1996-1 Trust, National Auto Finance 1997-1 Trust and
         National Auto Finance 1998-1 Trust of a Series, the Transferor is not
         engaged in any business transactions with NAFI or any of its
         Affiliates.

                                       17
<PAGE>   21

                           (iii) At least one co-trustee of the Transferor shall
         be a Person who is not, and will not be, a director, officer, employee
         or holder of any partnership interests or equity securities or other
         beneficial ownership interests of NAFI or any of its Affiliates.

                           (iv) The Transferor's funds and assets are not, and
         will not be, commingled with the funds of any other Person.

                           (v) The trust agreement of the Transferor requires it
         to maintain (A) correct and complete books and records of account, and
         (B) minutes of the meetings and other proceedings of its holders of
         beneficial ownership interests and trustees (including any
         co-trustees).

                  (o) Solvency; Fraudulent Conveyance. Each of NAFI and the
         Transferor is solvent and will not be rendered insolvent by the
         Transaction and, after giving effect to such Transaction, neither NAFI
         nor the Transferor will be left with an unreasonably small amount of
         capital with which to engage in its business. Neither NAFI nor the
         Transferor intends to incur, or believes that it has incurred, debts
         beyond its ability to pay such debts as they mature. Neither NAFI nor
         the Transferor is contemplating the commencement of insolvency,
         bankruptcy, liquidation or consolidation proceedings or the appointment
         of a receiver, liquidator, conservator, trustee or similar official in
         respect of NAFI or the Transferor, as the case may be, or any of their
         respective assets. The amount of consideration being received by the
         Transferor upon the sale of the Receivables and related Other Trust
         Property to the Trust constitutes reasonably equivalent value and fair
         consideration for such Receivables and related Other Trust Property.
         The amount of consideration being received by the Master Trust upon the
         sale of the Receivables and related Other Trust Property to Funding
         Trust II constitutes reasonably equivalent value and fair consideration
         for such Receivables and related Other Trust Property. The amount of
         consideration being received by Funding Trust II upon the sale of the
         Receivables and related Other Trust Property to the Transferor
         constitutes reasonably equivalent value and fair consideration for such
         Receivables and related Other Trust Property. The amount of
         consideration received by NAFI upon the transfer of the Receivables and
         related Other Trust Property to Funding Trust II constituted reasonably
         equivalent value and fair consideration for such Receivables and
         related Other Trust Property. Neither (i) the Master Trust, with
         respect to the Receivables and related Other Trust Property transferred
         by it to Funding Trust II nor (ii) Funding Trust II, with respect to
         the Receivables and related Other Trust Property transferred by it to
         the Transferor, is transferring any of the above-mentioned Receivables
         and related Other Trust Property with any intent to hinder, delay or
         defraud any of their respective creditors. The Transferor is not
         transferring the Receivables and related Other Trust Property to the
         Trust or selling the Securities and the Class B Notes , as provided in
         the Transaction Documents, with any intent to hinder, delay or defraud
         any of the Transferor's creditors.

<PAGE>   22

                  (p) Investment Company Act Compliance. Neither NAFI nor the
         Transferor is required to be registered as an "investment company"
         under the Investment Company Act.

                  (q) Good Title; Valid Transfer; Absence of Liens; Security
         Interest.

                           (i) Immediately prior to the sale of the Receivables
                  and related Other Trust Property by the Transferor to the
                  Trust pursuant to the Sale and Servicing Agreement on the
                  Closing Date, the Transferor was the owner of, and had good
                  and marketable title to, such property free and clear of all
                  Liens and Restrictions on Transferability, and had full right,
                  power and lawful authority to assign, transfer and pledge such
                  Receivables and related Other Trust Property. The Sale and
                  Servicing Agreement constitutes a valid sale, transfer and
                  assignment of the Receivables and related Other Trust Property
                  to the Trust, enforceable against creditors of and purchasers
                  of the Transferor. In the event that, in contravention of the
                  intention of the parties, the transfer of such Receivables and
                  related Other Trust Property by the Transferor to the Trust is
                  characterized as other than a sale, such transfer shall be
                  characterized as a secured financing, and the Trust shall have
                  a valid and perfected first priority security interest in the
                  Receivables and related Other Trust Property free and clear of
                  all Liens and Restrictions on Transferability.

                           (ii) Immediately prior to the pledge of the
                  Collateral by the Trust to the Trust Collateral Agent pursuant
                  to the Indenture, the Trust was the owner of, and had good and
                  marketable title to, the Receivables and related Other Trust
                  Property free and clear of all Liens and Restrictions on
                  Transferability, and had full right, trust power and lawful
                  authority to assign, transfer and pledge such property. The
                  Indenture constitutes a valid pledge of the Collateral to the
                  Trust Collateral Agent, and the Trust Collateral Agent shall
                  have a valid and perfected first priority security interest in
                  the Collateral, free and clear of all Liens and Restrictions
                  on Transferability.

                  (r) Perfection of Liens and Security Interest. On the Closing
         Date, the Lien and security interest in favor of the Trust Collateral
         Agent with respect to the Collateral will be perfected by the delivery
         of the Receivable Files to the Custodian, which Receivable Files the
         Custodian will hold on behalf of the Trust Collateral Agent, the filing
         of financing statements on Form UCC-1 in each jurisdiction where such
         recording or filing is necessary for the perfection of the security
         interest in favor of the Trustee and the establishment of the
         Collection Account, the Distribution Account, the Class A Note
         Distribution Account, the Class B Note Distribution Account and the
         Lockbox Account in accordance with the provisions of the Transaction
         Documents, and no other filings in any jurisdiction or any other
         actions (except as expressly provided herein) are necessary to perfect
         the Trustee Collateral Agent's first priority Lien on and security
         interest in the Collateral as against any third parties.

                  (s) Security Interest in Funds and Investments. Assuming the
         retention of funds in the Trust Accounts and the acquisition of
         Eligible Investments in accordance with the Transaction Documents, such
         funds and Eligible Investments will be subject to a valid and
         perfected, first priority security interest in favor of the Trust
         Collateral Agent on behalf of the Indenture Trustee (on behalf of the
         holders of the Securities) and Financial Security. Assuming the
         retention of funds in the Spread Account and the acquisition of
         Eligible Investments in accordance with the Spread Account Agreement,
         such funds and Eligible Investments will be subject to a valid and
         perfected, first priority security interest in favor of the Collateral
         Agent on behalf of Financial Security.

                  (t) Taxes. Each of NAFI and the Transferor, and each of their
         respective Subsidiaries, has filed all Federal and state tax returns
         which are required to be filed and paid all taxes, including any
         assessments received by it, to the extent that such taxes have become
         due. Any taxes, fees and other governmental charges payable by the
         Transferor or NAFI in connection with the Transaction, the execution
         and delivery of the Transaction Documents and the issuance of the
         Securities, the Class B Notes and the Certificate have been paid or

         property/casualty insurance security fund specified in Article 76 of
         the New York Insurance Law. In addition, each Offering Document which
         includes financial statements of Financial Security prepared in
         accordance with generally accepted accounting principles shall include
         the following statement immediately preceding such financial
         statements:

                           The New York State Insurance Department recognizes
                           only statutory accounting practices for determining
                           and reporting the financial condition and results of
                           operations of an insurance company, for determining
                           its solvency under the New York Insurance Law, and
                           for determining whether its financial condition
                           warrants the payment of a dividend to its
                           stockholders. No consideration is given by the New
                           York State Insurance Department to financial
                           statements prepared in accordance with generally
                           accepted accounting principles in making such
                           determinations.

<PAGE>   28

                           (2) Each Offering Document delivered subsequent to
                  the Date of Issuance shall be in form and substance
                  satisfactory to Financial Security in its sole discretion as
                  evidenced by Financial Security's prior written consent to the
                  use thereof.

                  (j) Special Purpose Entity.

                           (i) The Transferor shall conduct its business solely
         in its own name through its duly authorized officers or agents so as
         not to mislead others as to the identity of the entity with which those
         officers are concerned, and particularly will use its best efforts to
         avoid the appearance of conducting business on behalf of NAFI or any
         Affiliate thereof or that the assets of the Transferor are available to
         pay the creditors of NAFI or any Affiliate thereof. Without limiting
         the generality of the foregoing, all oral and written communications,
         including, without limitation, letters, invoices, purchase orders,
         Receivables, statements and loan applications, will be made solely in
         the name of the Transferor.

                           (ii) The Transferor shall maintain records and books
         of account separate from those of NAFI and the Affiliates thereof. The
         Transferor's books and records shall clearly reflect the transfer of
         the Receivables to the Trust as a sale of the Transferor's interest in
         the Receivables. The books of account and records of the Transferor
         will be separate from those of NAFI and its Affiliates and will be
         maintained at the address designated herein for receipt of notices,
         unless the Transferor shall otherwise advise the parties hereto in
         writing with respect to such address.

                           (iii) The Transferor shall obtain proper
         authorization of all action requiring approval of the co-trustees or
         holders of beneficial ownership interests of the Transferor, as the
         case may be. Meetings of the holders of beneficial ownership interests
         of the Transferor shall be held not less frequently than one time per
         annum and copies of each such authorization and the minutes of each
         such meeting shall be delivered to Financial Security within two weeks
         of such authorization or meeting, as the case may be.

                           (iv) Although the organizational expenses of the
         Transferor have been paid by NAFI, operating expenses and liabilities
         of the Transferor shall be paid from its own funds.

                           (v) The annual financial statements of the Transferor
         shall disclose the effects of the Transferor's transactions in
         accordance with generally accepted accounting principles and shall
         disclose that the assets of the Transferor are not available to pay
         creditors of NAFI or any Affiliate thereof.

                           (vi) The resolutions, agreements and other
         instruments of the Transferor underlying the transactions described in
         this Insurance Agreement and

                                       25
<PAGE>   29

         the other Transaction Documents shall be continuously maintained by the
         Transferor as official records of the Transferor separately identified
         and held apart from the records of NAFI and each Affiliate thereof.

                           (vii) The Transferor shall maintain an arm's-length
         relationship with NAFI and the Affiliates thereof and will not hold
         itself out as being liable for the debts of NAFI or any Affiliate
         thereof.

                           (viii) The Transferor shall keep its assets and its
         liabilities wholly separate from those of all other entities,
         including, but not limited to NAFI and the Affiliates thereof.

                  (k) Maintenance of Licenses. NAFI and the Transferor shall
         each maintain all licenses, permits, charters and registrations which
         are material to the performance by NAFI or the Transferor, as the case
         may be, of its business and of its respective obligations under this
         Insurance Agreement and each other Transaction Document.

                  (l) Registration Statements for the Securities. Each of NAFI
         and the Transferor shall (i) provide Financial Security with written
         notice at least 30 days prior to the filing of any registration
         statement relating to the Securities, the Class B Notes or the
         Certificate, (ii) provide Financial Security with a copy of such
         registration statement to be filed at least 15 days prior to such
         filing, (iii) prior to such filing, obtain the written consent of
         Financial Security with respect to the filing of such registration
         statement and (iv) provide Financial Security with any opinions of
         counsel as Financial Security may request in connection with the
         registration of the Securities, the Class B Notes or the Certificate
         under the Securities Act, which opinions shall be addressed to
         Financial Security and shall be in form and substance satisfactory to
         Financial Security.

                  (m) Incorporation of Covenants. NAFI and the Transferor shall
         each comply with their respective covenants set forth in the
         Transaction Documents and hereby incorporates such covenants by
         reference as if each were set forth herein.

                  (n) Release of Liens. NAFI and the Transferor shall each duly
         file or cause to be duly filed with respect to itself and on behalf of

         the Receivables and Other Trust Property and (ii) the financing
         statements on Form UCC-1 in each jurisdiction where such recording or
         filing is necessary for the perfection of Liens and security interest
         of the Trust Collateral Agent in favor of the Collateral.

                  (o) Notice of Default. In the event any notice is delivered to
         the Transferor under Section 5.01(d) concerning a failure in the
         performance or observance of any covenant or agreement on the part of
         the Servicer, NAFI or the Trust, the Transferor shall immediately
         deliver such notice to the Servicer, Financial Security, the Trust and
         NAFI.

respect to Funding Trust II and otherwise, as follows:

                  (a) Good Title; Valid Transfer; Absence of Liens; Security
         Interest. Immediately prior to the sale of the Receivables and related

         Agreement on the Closing Date, the Master Trust was the owner of, and
         had good and marketable title to, such property free and clear of all
         Liens and Restrictions on Transferability, and had full right, power
         and lawful authority to assign, transfer and pledge such Receivables

         right, power and lawful authority to assign, transfer and pledge such
         Receivables and related Other Trust Property. The Assignment Agreement
         constitutes a valid sale, transfer and assignment of the Receivables
         and related Other Trust Property to Funding Trust II, enforceable
         against creditors of and purchasers of the Master Trust. The Sale
         Agreement constitutes a valid sale, transfer and assignment of the
         Receivables and the related Other Trust Property to the Transferor,
         enforceable against creditors of and purchasers of Funding Trust II. In
         the event that, in contravention of the intention of the parties, (i)

         Master Trust to Funding Trust II or (ii) the transfer of the
         Receivables and

                                       31
<PAGE>   35

         related Other Trust Property by Funding Trust II to the Transferor is
         characterized as other than a sale, such transfer shall be
         characterized as a secured financing, and Funding Trust II or the
         Transferor, as applicable, shall have a valid and perfected first
         priority security interest in such Receivables and related Other Trust
         Property free and clear of all Liens and Restrictions on
         Transferability other than as imposed by the Transaction Documents.

                  (b) Compliance With Agreements and Applicable Laws. Each of

         any law, rule or regulation applicable to it, or that are required in
         connection with its performance under the Assignment Agreement and the
         Sale Agreement, respectively. Each of the Master Trust and Funding
         Trust II has not taken any action that would interfere with the
         enforcement of any rights under the Assignment Agreement and the Sale
         Agreement, respectively.

respect to the Master Trust and Funding Trust II. Each of NAFI and the
Transferor hereby agrees with respect to itself, with respect to the Master
Trust, with respect to Funding Trust II and otherwise, that during the Term of

         case may be, (B) with respect to any of the Receivables transferred by
         the Master Trust to Funding Trust II or Funding Trust II to the
         Transferor, or (C) in which a request has been made for certification

         Receivables transferred by the Master Trust to Funding Trust II or
         Funding Trust II to the Transferor; or

                           (ii) any other event, circumstance or condition that
         has resulted in a material adverse change in the ability of the Master
         Trust or Funding Trust II to perform its obligations under the
         Assignment Agreement or the Sale Agreement, respectively.

                  (b) Further Assurances. Each of NAFI and the Transferor will
         file, or cause to be filed, all necessary termination statements,
         assignments or other instruments, and any amendments or continuation
         statements relating thereto, necessary to be kept and filed in such

         Restrictions on Transferability created by or for the benefit of the
         Master Trust or Funding Trust II, as the case may be.

                  (c) Third-Party Beneficiary. The Transferor and NAFI agree
         that Financial Security shall have all rights of a third-party
         beneficiary in respect of the Assignment Agreement and the Sale
         Agreement and each of NAFI and the Transferor hereby restates the

         Offering Document that are incurred after the Date of Issuance. It is
         understood that Financial Security's auditors shall not incur any
         additional fees in respect of future Offering Documents except at the
         request of or with the consent of NAFI.

                  (e) Premium. In consideration of the issuance by Financial
         Security of the Policy, Financial Security shall be entitled to receive
         the Premium as and when due in accordance with the terms of the Premium
         Letter (i) in the case of Premium due on or before the Date of
         Issuance, directly from the Transferor and (ii) in the case of Premium
         due after the Date of Issuance, first, from monies available for such
         payment in accordance with Section 5.7 of the Sale and Servicing
         Agreement and second, to the extent that such monies are
         insufficient, from NAFI. The Premium paid hereunder or under the Sale
         and Servicing Agreement shall be nonrefundable without regard to
         whether Financial Security makes any payment under the Policy or any
         other circumstances relating to the Securities or

                                       34
<PAGE>   38

         provision being made for payment of the Securities prior to maturity.
         Although the Premium is fully earned by Financial Security as of the
         Closing Date, the Premium shall be payable in periodic installments as
         provided in the Premium Letter. Anything herein or in any of the
         Transaction Documents notwithstanding, upon the occurrence of an Event
         of Default, the entire outstanding balance of further installments of
         the Premium shall be immediately due and payable. All payments of
         Premium shall be made by wire transfer to an account designated from
         time to time by Financial Security by written notice to the Transferor
         and NAFI.

         Section 3.03. Reimbursement Obligation. Notwithstanding any of the
following provisions of this Section 3.03 to the contrary, the payment
obligations set forth in Sections 3.03(a), 3.03(b) (other than in respect of
amounts due from NAFI), 3.03(c) (other than in respect of amounts due from NAFI
and other amounts that, after due notice and any required passage of time, would
not be payable as a "Scheduled Payment" under the Policy), and 3.03(d)(v) shall
be non-recourse obligations with respect to NAFI, the Transferor or any
Affiliate of either (other than the Trust) and shall be payable only from monies
available for such payment in accordance with Section 5.7 of the Sale and
Servicing Agreement (except to the extent that any such payment obligation
arises from a failure to perform or default of NAFI, the Transferor or any of
their respective Affiliates under any Transaction Document or by reason of
negligence, willful misconduct or bad faith on the part of NAFI, the Transferor
or any of their respective Affiliates in the performance of its duties and
obligations thereunder or reckless disregard by NAFI, the Transferor or any of
their respective Affiliates of its duties and obligations thereunder). NAFI, the
Transferor and the Trust agree to pay to Financial Security the following
amounts as and when incurred:

                  (a) a sum equal to the total of all amounts paid by Financial
         Security under the Policy;

                  (b) interest on any and all amounts described in this Section
         3.03 or Section 3.02(e) from the date due to Financial Security
         pursuant to the provisions hereof until payment thereof in full,
         payable to Financial Security at the Late Payment Rate per annum;

                  (c) any payments made by Financial Security on behalf of, or
         advanced to, NAFI, in its capacity as Servicer, the Trust, the Owner
         Trustee, the Custodian, the Trust Collateral Agent, the Backup
         Servicer, the Collateral Agent or the Indenture Trustee, including,
         without limitation, any amounts payable by NAFI, in its capacity as
         Servicer, the Trust, the Owner Trustee, the Custodian, the Trust
         Collateral Agent, the Backup Servicer, the Collateral Agent or the
         Indenture Trustee pursuant to the Securities or any other Transaction
         Documents; and any payments made by Financial Security as, or in lieu
         of, any servicing, management, trustee, custodial or administrative
         fees payable, in the sole discretion of Financial Security to third
         parties in connection with the Transaction; and

                                       35
<PAGE>   39

                  (d) any and all out-of-pocket charges, fees, costs and
         expenses which Financial Security may reasonably pay or incur,
         including, but not limited to, attorneys' and accountants' fees and
         expenses, in connection with (i) in the event of payments under the
         Policy, any accounts established to facilitate payments under the
         Policy, to the extent Financial Security has not been immediately
         reimbursed on the date that any amount is paid by Financial Security
         under the Policy, or other administrative expenses relating to such
         payments under the Policy, (ii) the administration, enforcement,
         defense or preservation of any rights in respect of any of the
         Transaction Documents, including defending, monitoring or participating
         in any litigation or proceeding (including any insolvency or bankruptcy
         proceeding in respect of any Transaction participant or any Affiliate
         thereof) relating to any of the Transaction Documents, any party to any
         of the Transaction Documents or the Transaction, (iii) any amendment,
         waiver or other action with respect to, or related to, any Transaction
         Document whether or not executed or completed, (iv) any review or
         investigation made by Financial Security in those circumstances where
         its approval or consent is sought under any of the Transaction
         Documents, (v) the foreclosure against, sale or other disposition of
         any collateral securing any obligations under any of the Transaction
         Documents or otherwise in the discretion of Financial Security, or
         pursuit of any other remedies under any of the Transaction Documents,
         to the extent such costs and expenses are not recovered from such
         foreclosure, sale or other disposition, (vi) preparation of bound
         volumes of the Transaction Documents, and (vii) any Federal, state or
         local tax (other than taxes payable in respect of the gross income of
         Financial Security) or other governmental charge imposed in connection
         with the issuance of the Policy.

                  All such amounts are to be immediately due and payable without
         demand, in full, without any requirement on the part of Financial
         Security to seek reimbursement of such amounts from any other source of
         reimbursement or indemnity or to allocate such amount to any other
         transaction that may have benefited from the expenditure of such
         amounts.

         Section 3.04. Indemnification.

                  (a) Indemnification by NAFI and the Transferor. In addition to
         any and all rights of reimbursement, indemnification, subrogation and
         any other rights pursuant hereto or under law or in equity, each of
         NAFI and the Transferor, jointly and severally, agrees to pay, and to
         protect, indemnify and save harmless, Financial Security and its
         officers, directors, shareholders, employees, agents and each Person,
         if any, who controls Financial Security within the meaning of either
         Section 15 of the Securities Act or Section 20 of the Securities
         Exchange Act from and against any and all claims, losses, liabilities
         (including penalties), actions, suits, judgments, demands, damages,
         costs or expenses (including, without limitation, fees and expenses of
         attorneys, consultants and auditors and

                                       36
<PAGE>   40

         reasonable costs of investigations) of any nature arising out of or
         relating to the transactions contemplated by the Transaction Documents
         by reason of:

                           (i) any statement, omission or action (other than of
         or by Financial Security) in connection with the offering, issuance,
         sale, remarketing or delivery of the Securities, the Class B Notes or
         the Certificate;

                           (ii) the negligence, bad faith, willful misconduct,
         misfeasance, malfeasance or theft committed by any director, officer,
         employee or agent of the Trust, the Transferor or NAFI, as the case may
         be;

                           (iii) the breach by the Trust, the Transferor or
         NAFI, as the case may be, of any representation, warranty or covenant
         under any of the Transaction Documents or the occurrence, in respect of
         the Trust, the Transferor or NAFI, as the case may be, under any of the
         Transaction Documents of any "event of default" or any event which,
         with the giving of notice or the lapse of time or both, would
         constitute any "event of default";

                           (iv) the violation by the Trust, the Transferor or
         NAFI of any federal, state or foreign law, rule or regulation, or any
         judgment, order or decree applicable to it; or

                           (v) any untrue statement or alleged untrue statement
         of a material fact contained in the Registration Statement or any
         Offering Document or in any amendment or supplement thereto or any
         omission or alleged omission to state therein a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading, except insofar as such claims arise out of or are based
         upon any untrue statement or omission in the Financial Security
         Information, it being understood that in respect of the Offering
         Document, the Financial Security Information is limited to information
         included under the caption "THE NOTE INSURER" and the financial
         statements of Financial Security attached thereto as Exhibit [ ].

                  (b) Conduct of Actions or Proceedings. If any action or
         proceeding (including any governmental investigation) shall be brought
         or asserted against Financial Security, any officer, director,
         shareholder, employee or agent of Financial Security or any Person
         controlling Financial Security (individually, an "Indemnified Party"
         and, collectively, the "Indemnified Parties") in respect of which
         indemnity may be sought from the Transferor and NAFI (the "Indemnifying
         Party") hereunder, Financial Security shall promptly notify the
         Indemnifying Party in writing, and the Indemnifying Party shall assume
         the defense thereof, including the employment of counsel satisfactory
         to Financial Security and the payment of all expenses. An Indemnified
         Party shall have the right to employ separate counsel in any such
         action and to participate in the defense thereof at the expense of the
         Indemnified Party; provided, however, that the fees and expenses of
         such separate counsel shall be at the expense of the

                                       37
<PAGE>   41

         Indemnifying Party if (i) the Indemnifying Party has agreed to pay such
         fees and expenses, (ii) the Indemnifying Party shall have failed to
         assume the defense of such action or proceeding and employ counsel
         satisfactory to Financial Security in any such action or proceeding or
         (iii) the named parties to any such action or proceeding (including any
         impleaded parties) include both the Indemnified Party and the
         Indemnifying Party, and the Indemnified Party shall have been advised
         by counsel that (A) there may be one or more legal defenses available
         to it which are different from or additional to those available to the
         Indemnifying Party and (B) the representation of the Indemnifying Party
         and the Indemnified Party by the same counsel would be inappropriate or
         contrary to prudent practice (in which case, if the Indemnified Party
         notifies the Indemnifying Party in writing that it elects to employ
         separate counsel at the expense of the Indemnifying Party, the
         Indemnifying Party shall not have the right to assume the defense of
         such action or proceeding on behalf of such Indemnified Party, it being
         understood, however, that the Indemnifying Party shall not, in
         connection with any one such action or proceeding or separate but
         substantially similar or related actions or proceedings in the same
         jurisdiction arising out of the same general allegations or
         circumstances, be liable for the reasonable fees and expenses of more
         than one separate firm of attorneys at any time for the Indemnified
         Parties, which firm shall be designated in writing by Financial
         Security). The Indemnifying Party shall not be liable for any
         settlement of any such action or proceeding effected without its
         written consent to the extent that any such settlement shall be
         prejudicial to the Indemnifying Party but, if settled with its written
         consent, or if there be a final judgment for the plaintiff in any such
         action or proceeding with respect to which the Indemnifying Party shall
         have received notice in accordance with this subsection (b), the
         Indemnifying Party agrees to indemnify and hold the Indemnified Parties
         harmless from and against any loss or liability by reason of such
         settlement or judgment.

                  (c) Contribution. To provide for just and equitable
         contribution if the indemnification provided by the Indemnifying Party
         is determined to be unavailable for any Indemnified Party (other than
         due to application of this Section), the Indemnifying Party shall
         contribute to the losses incurred by the Indemnified Party on the basis
         of the relative fault of the Indemnifying Party, on the one hand, and
         the Indemnified Party, on the other hand.

         Section 3.05. Subrogation. Subject only to the priority of payment
provisions of the Sale and Servicing Agreement, each of the Trust, the
Transferor and NAFI acknowledges that, to the extent of any payment made by
Financial Security pursuant to the Policy, Financial Security is to be fully
subrogated to the extent of such payment and any additional interest due on any
late payment, to the rights of the holders of the Securities to any moneys paid
or payable in respect of the Securities under the Transaction Documents or
otherwise. Each of the Trust, the Transferor and NAFI agrees to such subrogation
and, further, agrees to execute such instruments and to take such actions as, in
the sole judgment of Financial Security, are necessary to evidence such

                                       38
<PAGE>   42

subrogation and to perfect the rights of Financial Security to receive any
moneys paid or payable in respect of the Securities under the Transaction
Documents or otherwise.

                                  ARTICLE IV.

                               FURTHER AGREEMENTS

         Section 4.01. Effective Date; Term of Agreement. This Insurance
Agreement shall take effect on the Date of Issuance and shall remain in effect
until the later of (a) such time as Financial Security is no longer subject to a
claim under the Policy and the Policy shall have been surrendered to Financial
Security for cancellation and (b) all amounts payable to Financial Security and
the holders of the Securities under the Transaction Documents and under the
Securities have been paid in full; provided, however, that the provisions of

Insurance Agreement.

         Section 4.02. Further Assurances and Corrective Instruments. To the
extent permitted by law, each of the Trust, the Transferor, and NAFI agrees that
it will, from time to time, execute, acknowledge and deliver, or cause to be
executed, acknowledged and delivered, such supplements hereto and such further
instruments as Financial Security may reasonably request and as may be required
in Financial Security's reasonable judgment to effectuate the intention of or
facilitate the performance of this Insurance Agreement and the intent of the
parties hereto.

         Section 4.03. Obligation Absolute. The payment obligations of the
Trust, the Transferor and NAFI hereunder shall be absolute and unconditional,
and shall be paid strictly in accordance with this Insurance Agreement under all
circumstances irrespective of the following:

                           (i) any lack of validity or enforceability of, or any
         amendment or other modifications of, or waiver with respect to, any of
         the Transaction Documents, the Securities or the Policy;

                           (ii) any exchange or release of any other obligations
         hereunder;

                           (iii) the existence of any claim, setoff, defense,
         reduction, abatement or other right which the Trust, the Transferor or
         NAFI may have at any time against Financial Security or any other
         Person;

                           (iv) any document presented in connection with the
         Policy proving to be forged, fraudulent, invalid or insufficient in any
         respect, including any failure to strictly comply with the terms of the
         Policy, or any statement therein being untrue or inaccurate in any
         respect;

                           (v) any failure of the Transferor or the Trust to
         receive the proceeds from the sale of the Securities;

                                       39
<PAGE>   43

                           (vi) any breach by the Trust, the Transferor or NAFI
         of any representation, warranty or covenant contained in any of the
         Transaction Documents;

                           (vii) any payment by Financial Security under the
         Policy against presentation of a certificate or other document which
         does not strictly comply with the terms of the Policy; or

                           (viii) any other circumstances, other than payment in
         full, which might otherwise constitute a defense available to, or
         discharge of the Trust, the Transferor or NAFI in respect of any
         Transaction Document.

                  (b) Each of the Trust, the Transferor and NAFI and any and all
         others who are now or may become liable for all or part of the
         obligations of any of them under this Insurance Agreement agree to be
         bound by this Insurance Agreement and (i) to the extent permitted by
         law, waive and renounce any and all redemption and exemption rights and
         the benefit of all valuation and appraisement privileges against the
         indebtedness, if any, and obligations evidenced by any Transaction
         Document or by any extension or renewal thereof; (ii) waive presentment
         and demand for payment, notices of nonpayment and of dishonor, protest
         of dishonor and notice of protest; (iii) waive all notices in
         connection with the delivery and acceptance hereof and all other
         notices in connection with the performance, default or enforcement of
         any payment hereunder except as required by the Transaction Documents;
         (iv) waive all rights of abatement, diminution, postponement or
         deduction, or to any defense other than payment, or to any right of
         setoff or recoupment arising out of any breach under any of the
         Transaction Documents, by any party thereto or any beneficiary thereof,
         or out of any obligation at any time owing to the Trust, the Transferor
         or NAFI; (v) agree that any consent, waiver or forbearance hereunder
         with respect to an event shall operate only for such event and not for
         any subsequent event; (vi) consent to any and all extensions of time
         that may be granted by Financial Security with respect to any payment
         hereunder or other provisions hereof and to the release of any security
         at any time given for any payment hereunder, or any part thereof, with
         or without substitution, and to the release of any Person or entity
         liable for any such payment; and (vii) consent to the addition of any
         and all other makers, endorsers, guarantors and other obligors for any
         payment hereunder, and to the acceptance of any and all other security
         for any payment hereunder, and agree that the addition of any such
         obligors or security shall not affect the liability of the parties
         hereto for any payment hereunder.

                  (c) Nothing herein shall be construed as prohibiting the
         Trust, NAFI or the Transferor from pursuing any rights or remedies it
         may have against any Person other than Financial Security in a separate
         legal proceeding.

         Section 4.04. Assignments; Reinsurance; Third-Party Rights. This
Insurance Agreement shall be a continuing obligation of the parties hereto and
shall be binding

                                       40
<PAGE>   44

upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns. None of the Trust, the Transferor nor NAFI may
assign its rights under this Insurance Agreement, or delegate any of its duties
hereunder, without the prior written consent of Financial Security. Any
assignment made in violation of this Insurance Agreement shall be null and void.

                  (a) Financial Security shall have the right to give
         participations in its rights under this Insurance Agreement and to
         enter into contracts of reinsurance with respect to the Policy upon
         such terms and conditions as Financial Security may in its discretion
         determine; provided, however, that no such participation or reinsurance
         agreement or arrangement shall relieve Financial Security of any of its
         obligations hereunder or under the Policy.

                  (b) In addition, Financial Security shall be entitled to
         assign or pledge to any bank or other lender providing liquidity or
         credit with respect to the Transaction or the obligations of Financial
         Security in connection therewith any rights of Financial Security under
         the Transaction Documents, or with respect to any real or personal
         property or other interests pledged to Financial Security, or in which
         Financial Security has a security interest, in connection with the
         Transaction.

                  (c) Except as provided herein with respect to participants and
         reinsurers, nothing in this Insurance Agreement shall confer any right,
         remedy or claim, express or implied, upon any Person, including,
         particularly, any holder of the Notes or Certificateholder other than
         Financial Security, against the Trust, the Transferor or NAFI, and all
         the terms, covenants, conditions, promises and agreements contained
         herein shall be for the sole and exclusive benefit of the parties
         hereto and their successors and permitted assigns. None of the Trust
         Collateral Agent, the Indenture Trustee, the Owner Trustee, any holder
         of the Notes or any Certificateholder shall have any right to payment
         from any premiums paid or payable hereunder or from any other amounts
         paid by NAFI or the Transferor pursuant to Section 3.02, 3.03 or 3.04
         hereof.

         Section 4.05. Liability of Financial Security. Neither Financial
Security nor any of its officers, directors or employees shall be liable or
responsible for: (a) the use which may be made of the Policy by the Trust
Collateral Agent or for any acts or omissions of the Trust Collateral Agent in
connection therewith or (b) the validity, sufficiency, accuracy or genuineness
of documents delivered to Financial Security (or its Fiscal Agent) in connection
with any claim under the Policy, or of any signatures thereon, even if such
documents or signatures should in fact prove to be in any or all respects
invalid, insufficient, fraudulent or forged (unless Financial Security had
actual knowledge thereof). In furtherance and not in limitation of the
foregoing, Financial Security (or its Fiscal Agent) may accept documents that
appear on their face to be in order, without responsibility for further
investigation.

         jurisdiction over any of the parties to any of the Transaction
         Documents or any property thereof shall find or rule that any material

                  (d) the Trust, the Transferor, the Servicer, Funding Trust II,

         Section 5.02. Remedies; Waivers. Upon the occurrence of an Event of

remedies set forth below:

                           (i) declare all or a portion of the Premium
         Supplement that has accrued or will accrue payable, and the same shall
         thereupon (A) be immediately due and payable to the extent then accrued
         and (B) become immediately due and payable upon accrual to the extent
         accruing thereafter, whether or not Financial Security shall have
         declared an "Event of Default" or shall have exercised, or be entitled
         to exercise, any other rights or remedies hereunder;

                           (ii) exercise any rights and remedies available under
         the Transaction Documents in its own capacity or in its capacity as the
         Person entitled to exercise the rights of the Controlling Party under
         the Transaction Documents,

                                       44
<PAGE>   48

         including, without limitation, its right to accelerate the Securities
         or to terminate NAFI as Servicer and to appoint a substitute servicer;
         or

                           (iii) take whatever action at law or in equity may
         appear necessary or desirable in its judgment to enforce performance of
         any obligation of the Trust, the Transferor or NAFI under the
         Transaction Documents.

                  (b) Unless otherwise expressly provided, no remedy herein
         conferred upon or reserved is intended to be exclusive of any other
         available remedy, but each remedy shall be cumulative and shall be in
         addition to other remedies given under the Transaction Documents or
         existing at law or in equity. No delay or failure to exercise any right
         or power accruing under any Transaction Document upon the occurrence of
         any Event of Default or otherwise shall impair any such right or power
         or shall be construed to be a waiver thereof, but any such right and
         power may be exercised from time to time and as often as may be deemed
         expedient. In order to entitle Financial Security to exercise any
         remedy reserved to Financial Security in this Article, it shall not be
         necessary to give any notice, other than such notice as may be
         expressly required in this Article.

                  (c) If any proceeding has been commenced to enforce any right
         or remedy under this Insurance Agreement and such proceeding has been
         discontinued or abandoned for any reason, or has been determined
         adversely to Financial Security, then and in every such case the
         parties hereto shall, subject to any determination in such proceeding,
         be restored to their respective former positions hereunder, and,
         thereafter, all rights and remedies of Financial Security shall
         continue as though no such proceeding had been instituted.

                  (d) Financial Security shall have the right, to be exercised
         in its complete discretion, to waive any covenant, Default or Event of
         Default by a writing setting forth the terms, conditions and extent of
         such waiver signed by Financial Security and delivered to the Trust,
         the Transferor and NAFI. Any such waiver may only be effected in
         writing duly executed by Financial Security, and no other course of
         conduct shall constitute a waiver of any provision hereof. Unless such
         writing expressly provides to the contrary, any waiver so granted shall
         extend only to the specific event or occurrence so waived and not to
         any other similar event or occurrence.

immediately available funds to the account number provided in the Premium Letter
before 12:00 p.m. (New York, New York time) on the date when due or as Financial
Security shall otherwise direct by written notice to the Trust, the Transferor

Day, then such payment or expiration of time period shall be made or occur on
the next succeeding Business Day with the same force and effect as if such
payment was made or time period expired on the scheduled date of payment or

Agreement shall bear interest at the Late Payment Rate from the date due to the

         Section 6.04. Confidentiality. Any information obtained by Financial
Security pursuant to this Insurance Agreement shall be held in confidence by
Financial Security unless (i) such information has become available to the
public other than as a result of a disclosure by or through Financial Security,
(ii) such information was available to Financial Security on a nonconfidential
basis prior to its disclosure to Financial Security hereunder, (iii) Financial
Security shall be required in connection with any legal or regulatory proceeding
to disclose such information, or (iv) Financial Security, in its sole
discretion, deems it necessary to disclose such information to the Rating
Agencies; provided, that, in any such instance, Financial Security will use its
best efforts to notify the Trust, the Transferor or NAFI of its intention to
make any such disclosure prior to making any such disclosure and, in the case of
disclosure to a Rating Agency, Financial Security shall notify such Rating
Agency that such information is confidential and should be treated as such by
such Rating Agency.

         Section 6.05. Severability. In the event that any provision of this
Insurance Agreement shall be held invalid or unenforceable by any court of
competent jurisdiction, the parties hereto agree that such holding shall not
invalidate or render unenforceable any other provision hereof. The parties
hereto further agree that the holding by any court of competent jurisdiction
that any remedy pursued by any party hereto is unavailable or unenforceable
shall not affect in any way the ability of such party to pursue any other remedy

follows:

         (a) Organization, Etc. Financial Security is a stock insurance company
duly organized, validly existing and authorized to transact financial guaranty
insurance business under the laws of the State of New York.

         (b) Authorization, Etc. The Policy and the Financial Security
Agreements have been duly authorized, executed and delivered by Financial
Security.

         (c) Validity, Etc. The Policy and the Financial Security Agreements
constitute valid and binding obligations of Financial Security, enforceable
against Financial Security in accordance with their terms, subject, as to the
enforcement of remedies, to bankruptcy, insolvency, reorganization,
rehabilitation, moratorium and other similar laws affecting the enforceability
of creditors' rights generally applicable in the event of the bankruptcy or
insolvency of Financial Security and to the application of general principles of
equity and subject, in the case of this Agreement, to principles of public
policy limiting the right to enforce the indemnification provisions contained
herein.

         (d) Exemption From Registration. The Policy is exempt from registration
under the Securities Act.

         (e) No Conflicts. Neither the execution or delivery by Financial
Security of the Policy or the Financial Security Agreements, nor the performance
by Financial Security of its obligations thereunder, will conflict with any
provision of the certificate of incorporation or the bylaws of Financial
Security nor result in a breach of, or constitute a

                                                                               3
<PAGE>   5

default under, any material agreement or other instrument to which Financial
Security is a party or by which any of its property is bound nor violate any
judgment, order or decree applicable to Financial Security of any governmental
or regulatory body, administrative agency, court or arbitrator having
jurisdiction over Financial Security (except that, in the published opinion of
the Commission, the indemnification provisions of this Agreement, insofar as
they relate to indemnification for liabilities arising under the Securities Act,
are against public policy as expressed in the Securities Act and are therefore
unenforceable).

         (f) Financial Information. The consolidated balance sheets of Financial
Security as of December 31, 1998 and December 31, 1997 and the related
consolidated statements of income, changes in shareholder equity and cash flows
for the fiscal years then ended and the interim consolidated balance sheet of
Financial Security as of June 30, 1999, and the related statements of income,
changes in shareholder equity and cash flows for the interim period then ended,
furnished by Financial Security to the Company, fairly present in all material
respects the financial condition of Financial Security as of such dates and for
such periods in accordance with generally accepted accounting principles
consistently applied (subject as to interim statements to normal year-end
adjustments) and since the date of the most current interim consolidated balance
sheet referred to above there has been no change in the financial condition of
Financial Security which would materially and adversely affect its ability to
perform its obligations under the Policy.

         (g) Financial Security Information. The information in the Offering
Memorandum set forth under the caption "The Note Insurer", (as revised from time
to time in accordance with the provisions hereof, the "Financial Security
Information") is limited and does not purport to provide the scope of disclosure
required to be included in an Offering Memorandum with respect to a registrant
in connection with the offer and sale of securities of such registrant
registered under the Securities Act. Within such limited scope of disclosure,
however, as of the date of such Offering Memorandum and as of the closing date,
the Financial Security Information does not contain any untrue statement of a
material fact, or omit to state a material fact necessary to make the statements
contained therein, in the light of the circumstances under which they were made,
not misleading.

         (h) Additional Information. Financial Security will furnish to the
Company, upon request of the Company, as the case may be, copies of Financial
Security's most recent financial statements (annual or interim, as the case may
be) which fairly present in all material respects the financial condition of
Financial Security as of the dates and for the periods indicated, in accordance
with generally accepted accounting principles consistently applied except as
noted therein (subject, as to interim statements, to normal year-end
adjustments). In addition, if the delivery of an Offering Memorandum relating to
the Securities is required at any time prior to the expiration of nine months
after the time of issuance of the Offering Memorandum in connection with the
offering or sale of the Securities, the Company will notify Financial Security
of such requirement to deliver an Offering Memorandum and Financial Security
will promptly provide the Company with any revisions to the Financial Security
Information that are in the judgment of

                                                                               4
<PAGE>   6

Financial Security necessary to prepare an amended Offering Memorandum or a
supplement to the Offering Memorandum.

         (i) Opinion of Counsel. Financial Security will furnish to the Company
on the closing date for the sale of the Securities an opinion of its Assistant
General Counsel, to the effect set forth in Exhibit A attached hereto, dated
such closing date and addressed to the Company.

         (j) Consents and Reports of Independent Accountants. Financial Security
will furnish to the Company, upon request, as comfort from its independent
accountants in respect of its financial condition, (i) at the expense of the
Person specified in the Insurance Agreement, a copy of the Offering Memorandum,
including either a manually signed consent or a manually signed report of
Financial Security's independent accountants, and (ii) the quarterly review
letter by Financial Security's independent accountants in respect of the most
recent interim financial statements of Financial Security.

Nothing in this Agreement shall be construed as a representation or warranty by
Financial Security concerning the rating of its insurance financial strength by
Moody's Investors Service, Inc. or its insurer financial strength by Standard &
Poor's Ratings Services, a division of The McGraw Hill Companies, or any other
rating agency (collectively, the "Rating Agencies"). The Rating Agencies, in
assigning such ratings, take into account facts and assumptions not described in
the Offering Memorandum and the facts and assumptions considered by the Rating
Agencies, and the ratings issued thereby, are subject to change over time.

Section 3.        Indemnification.

         (a) Financial Security agrees, upon the terms and subject to the
conditions provided herein, to indemnify, defend and hold harmless each Company
Party against (i) any and all Losses incurred by them with respect to the offer
and sale of the Securities and resulting from Financial Security's breach of any
of its representations, warranties or agreements set forth in Section 2 hereof
and (ii) any and all Losses to which any Company Party may become subject, under
the Securities Act or otherwise, insofar as such Losses arise out of or result
from an untrue statement of a material fact contained in any Offering Document
or the omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or omission was made
in the Financial Security Information included therein in accordance with the
provisions hereof.

         (b) Upon the incurrence of any Losses for which a party is entitled to
indemnification hereunder, the Indemnifying Party shall reimburse the
Indemnified Party promptly upon establishment by the Indemnified Party to the
Indemnifying Party of the Losses incurred.

                                                                               5
<PAGE>   7

Section 4. Indemnification Procedures. Except as provided below in Section 5
with respect to contribution, the indemnification provided herein by an
Indemnifying Party shall be the exclusive remedy of any and all Indemnified
Parties for the breach of a representation, warranty or agreement hereunder by
an Indemnifying Party; provided, however, that each Indemnified Party shall be
entitled to pursue any other remedy at law or in equity for any such breach so
long as the damages sought to be recovered shall not exceed the Losses incurred
thereby resulting from such breach. In the event that any action or regulatory
proceeding shall be commenced or claim asserted which may entitle an Indemnified
Party to be indemnified under this Agreement, such party shall give the
Indemnifying Party written or telegraphic notice of such action or claim
reasonably promptly after receipt of written notice thereof. The Indemnifying
Party shall be entitled to participate in and, upon notice to the Indemnified
Party, assume the defense of any such action or claim in reasonable cooperation
with, and with the reasonable cooperation of, the Indemnified Party. The
Indemnified Party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof at the expense of the
Indemnified Party; provided however, that the fees and expenses of such separate
counsel shall be at the expense of the Indemnifying Party if (i) the
Indemnifying Party has agreed to pay such fees and expenses, (ii) the
Indemnifying Party shall have failed to assume the defense of such action or
proceeding and employ counsel satisfactory to the Indemnified Party in any such
action or proceeding or (iii) the named parties to any such action or proceeding
(including any impleaded parties) include both the Indemnified Party and the
Indemnifying Party, and the Indemnified Party shall have been advised by counsel
that (A) there may be one or more legal defenses available to it which are
different from or additional to those available to the Indemnifying Party and
(B) the representation of the Indemnifying Party and the Indemnified Party by
the same counsel would be inappropriate or contrary to prudent practice in which
case, if the Indemnified Party notifies the Indemnifying Party in writing that
it elects to employ separate counsel at the expense of the Indemnifying Party,
the Indemnifying Party shall not have the right to assume the defense of such
action or proceeding on behalf of such Indemnified Party it being understood,
however, that the Indemnifying Party shall not, in connection with any one such
action or proceeding or separate but substantially similar or related actions or
proceedings in the same jurisdiction arising out of the same general allegations
or circumstances, be liable for the reasonable fees and expenses of more than
one separate firm of attorneys at any time for all the Company Parties and one
such firm for all Financial Security Parties, as the case may be, which firm
shall be designated in writing by the Company in respect of the Company Parties
and by Financial Security in respect of the Financial Security Parties. The
Indemnifying Party shall not be liable for any settlement of any such claim or
action unless the Indemnifying Party shall have consented thereto or be in
default in its obligations hereunder. Any failure by an Indemnified Party to
comply with the provisions of this Section shall relieve the Indemnifying Party
of liability only if such failure is prejudicial to the position of the
Indemnifying Party and then only to the extent of such prejudice.

                                                                               6

Section 5.        Contribution.

         (a) To provide for just and equitable contribution if the
indemnification provided by any Indemnifying Party is determined to be
unavailable for any Indemnified Party (other than due to application of this
Section 5), each Indemnifying Party shall contribute to the Losses arising from
any breach of any of its representations, warranties or agreements contained in
this Agreement on the basis of the relative fault of each of the parties as set
forth in Section 5(b) below; provided, however, that an Indemnifying Party shall
in no event be required to contribute to all Indemnified Parties an aggregate
amount in excess of the Losses incurred by such Indemnified Parties resulting
from the breach of representations, warranties or agreements contained in this
Agreement.

         (b) The relative fault of each Indemnifying Party, on the one hand, and
of each Indemnified Party, on the other, shall be determined by reference to,
among other things, whether the breach of, or alleged breach of, any
representations, warranties or agreements contained in this Agreement relates to
information supplied by, or action within the control of, the Indemnifying Party
or the Indemnified Party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such breach.

         (c) The parties agree that Financial Security shall be solely
responsible for the Financial Security Information, and that the balance of the
Offering Document shall be the responsibility of the Company.

         (d) No Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

         (e) Upon the incurrence of any Losses entitled to contribution
hereunder, the contributor shall reimburse the party entitled to contribution
promptly upon establishment by the party entitled to contribution to the
contributor of the Losses incurred.

                                    EXHIBIT A

                      OPINION OF ASSISTANT GENERAL COUNSEL

                  Based upon the foregoing, I am of the opinion that:

         1. Financial Security is a stock insurance company duly organized,
validly existing and authorized to transact financial guaranty insurance
business under the laws of the State of New York.

         2. The Policy and the Financial Security Agreements have been duly
authorized, executed and delivered by Financial Security.

         3. The Policy and the Financial Security Agreements constitute valid
and binding obligations of Financial Security, enforceable against Financial
Security in accordance with their terms, subject, as to the enforcement of
remedies, to bankruptcy, insolvency, reorganization, rehabilitation, moratorium
and other similar laws affecting the enforceability of creditors' rights
generally applicable in the event of the bankruptcy or insolvency of Financial
Security and to the application of general principles of equity and subject, in
the case of the Indemnification Agreement, to principles of public policy
limiting the right to enforce the indemnification provisions contained therein
insofar as they relate to indemnification for liabilities arising under
applicable securities laws.

         4. The Policy is exempt from registration under the Securities Act of
1933, as amended (the "Act").

         5. Neither the execution or delivery by Financial Security of the
Policy or the Financial Security Agreements, nor the performance by Financial
Security of its obligations thereunder, will conflict with any provision of the
certificate of incorporation or the bylaws of Financial Security or, to the best
of my knowledge, result in a breach of, or constitute a default under, any
agreement or other instrument to which Financial Security is a party or by which
it or any of its property is bound or, to the best of my knowledge, violate any
judgment, order or decree applicable to Financial Security of any governmental
or regulatory body, administrative agency, court or arbitrator having
jurisdiction over Financial Security (except that in the published opinion of
the Securities and Exchange Commission the indemnification provisions of the
Indemnification Agreement, insofar as they relate to indemnification for
liabilities arising under the Act, are against public policy as expressed in the
Act and are therefore unenforceable).

         In addition, please be advised that I have reviewed the description of
Financial Security under the caption "The Insurer" in the Offering Memorandum
dated September 24, 1999, (the "Offering Document") of the Company with respect
to the Securities. The information provided in the Offering Document with
respect to Financial Security is limited and does not purport to provide the
scope of disclosure required to be

                                                                             A-1

included in an Offering Memorandum with respect to a registrant under the Act in
connection with the public offer and sale of securities of such registrant.
Within such limited scope of disclosure, however, there has not come to my
attention any information which would cause me to believe that the description
of Financial Security referred to above, as of the date of the Offering
Document, contained any untrue statement of a material fact or omitted to state
a material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading (except that no opinion
is rendered with respect to any financial statements or other financial
information contained or referred to therein).

                                                                               2
