                        AMOUNT AND TERMS OF THE PURCHASES

                  SECTION 2.01. RECEIVABLES PURCHASE FACILITY. ING shall,
subject to the terms and conditions hereinafter set forth, make purchases from
Triple-A and the Seller of ING Receivables Interests from time to time on any
ING Receivables Interest Purchase Date during the period from the date the
conditions precedent in SECTION 3.01 are first satisfied to the ING Amortization
Date. Under no circumstances shall ING make any ING Receivables Interest
Purchase if, after giving effect to such ING Receivables Interest Purchase, (a)
the aggregate outstanding ING Capital hereunder would exceed the least of (i)
the ING Facility Limit or (ii) the ING Capital Limit, or (b) the aggregate
outstanding Combined Capital would exceed the least of (i) the Combined Facility
Limit or (ii) the Combined Capital Limit. The Capital Limit and Combined Capital
Limit in effect on any date shall be determined by reference to the most recent
Settlement Report delivered by the Seller to Triple-A and ING in accordance with
SECTION 5.02(f) of the Triple-A Purchase Agreement (i) as adjusted (A) on the
most recent Settlement Date to reflect additional Eligible Receivables sold on
such Settlement Date since the delivery of such Settlement Report and (B) on the
most recent ING Receivables Interest Purchase Date to reflect any additional ING
Receivable Interest Purchase since the delivery of such Settlement Report, and
(ii) as adjusted on any other date of determination to eliminate from the
Discounted Eligible Receivables Balance any Receivables which were Eligible
Receivables as of the dates reflected in the Settlement Report but which no
longer satisfy the criteria for Eligible Receivables.

                  SECTION 2.02.  MAKING PURCHASES OF RECEIVABLES INTERESTS.

                  (a) SALE NOTICE. Whenever the Seller wishes to have ING
         Receivables Interests sold to ING, it shall deliver to ING, with a copy
         to the Collateral Agent and the Administrative Agent, a notice ("ING
         SALE NOTICE") in substantially the form of EXHIBIT A hereto no later
         than 10:00 A.M. (New York City time) on the second Business Day

                                       2
<Page>

         immediately prior to the proposed ING Receivables Interest Purchase
         Date, with a copy to Triple-A. Each ING Sale Notice shall be by
         telephone, telex, telecopy, cable or other facsimile transmission (in
         the case of any such Sale Notice by telephone, confirmed immediately in
         writing) and shall specify therein (i) the aggregate initial ING
         Capital to be funded in connection with such ING Receivables Interest
         Purchase, (ii) the date of such ING Receivables Interest Purchase and
         (iii) the amount, if any, to be funded pursuant to the Triple-A
         Purchase Agreement on such date.

                  (b) AMOUNT OF PURCHASED ASSETS; DEFERRED PURCHASE PRICE. The
         consideration for each ING Receivables Interest Purchase shall consist
         of ING Capital funded under this ING Purchase Agreement. The amount of
         the Deferred Purchase Price under the Triple-A Purchase Agreement for
         the Purchased Assets shall be reduced pursuant to the Triple-A Purchase
         Agreement to reflect each related ING Receivables Interest Purchase.

                  (c) FUNDING. ING shall, before 3:00 P.M. (New York City time)
         on the proposed ING Receivables Interest Purchase Date of each ING
         Receivables Interest Purchase, subject to the applicable conditions set
         forth in ARTICLE III, on behalf of Triple-A, make available to the
         Seller a wire transfer of such funds in accordance with the Seller's
         written wire transfer instructions.

                  (d) CHARACTERIZATION. It is the express intent of the parties
         hereto that the conveyance of the ING Receivables Interest by Triple-A
         to ING be construed as a sale of the ING Receivables Interest by
         Triple-A to ING and not as a pledge of the ING Receivables Interest by
         Triple-A to ING to secure a debt or other obligation of Triple-A.
         However, if, notwithstanding the aforementioned intent of the parties,
         the ING Receivables Interest is held to be property of Triple-A, then,
         (a) it is the express intent of the parties that such conveyance be
         deemed a pledge of the ING Receivables Interest by Triple-A to ING to
         secure a debt or other obligation of Triple-A, and (b) (i) this
         Agreement shall also be deemed to be a security agreement within the
         meaning of Article 9 of the Uniform Commercial Code of the applicable
         jurisdiction, and (ii) the conveyance provided for herein shall be
         deemed to be a grant by Triple-A to ING of a security interest in all
         of Triple-A's right, title and interest in and to the ING Receivables
         Interest, and all amounts payable to the holder of the ING Receivables
         Interest in accordance with the terms thereof, and all proceeds of the
         conversion, voluntary or involuntary, of the foregoing into cash,
         instruments, securities or other property. Triple-A shall take such
         actions, at the expense of the Seller and ING, as may be necessary to
         ensure that, if this Agreement were deemed to create a security
         interest in the ING Receivables Interest, such security interest would
         be deemed to be a perfected security interest of first priority under
         applicable law and will be maintained as such throughout the term of
         this Agreement. Triple-A does hereby consent to the filing by ING of
         financing statements to perfect the transactions contemplated hereby
         without the signature of Triple-A.

                  SECTION 2.03. REDUCTION OF ING CAPITAL. (a) On each Settlement
Date, subject to SECTION 5.01, the amount required to be distributed to ING
pursuant to clause (ii) of SECTION 2.04 hereof in reduction of ING Capital shall
be an amount equal to the excess of ING Capital over the ING Capital Limit, such
that, following the application of such payments to outstanding ING Capital, the
ING Capital Limit equals or exceeds the outstanding ING Capital.

                                       3

                  (b) Immediately upon the consummation of a sale of securities
         by or on behalf of the Seller or an Affiliate thereof, secured, in
         whole or in part, by all or a portion of the Purchased Assets, the
         entire outstanding amount of ING Capital shall be due and payable to
         ING, PROVIDED, however, that, if the proceeds of such sale are not
         sufficient to pay all amounts due under the Triple-A Purchase Agreement
         in connection therewith, the funds shall be paid to the Collateral
         Agent for distribution in accordance with SECTION 6.11 of the Triple-A
         Purchase Agreement and such payment shall be subject to the priority of
         payments and other terms described in SECTION 5.01.

                  SECTION 2.04. PAYMENT DATE ALLOCATIONS. On each Settlement
Date, the Administrative Agent shall, subject to SECTION 5.01, distribute to
ING, the ING Yield and other ING Obligations, to the extent payable pursuant to
SECTION 6.11 of the Triple-A Purchase Agreement, to be applied by ING as
follows:

                  (i)      To pay ING Yield;

                  (ii)     To repay ING Capital; and

                  (iii)    To pay any other ING Obligations which may be due and
         owing at such time.

                  SECTION 2.05. PAYMENTS AND COMPUTATIONS, ETC. All amounts to
be distributed by the Administrative Agent hereunder shall, subject to SECTION
5.01, be distributed by the Administrative Agent pursuant to SECTION 6.11 of the
Triple-A Purchase Agreement in immediately available funds to ING not later than
2:00 P.M. (New York City time) on the date on which payable. Payments received
by ING after such time shall be deemed to have been received on the next
Business Day.

                  SECTION 2.06. ING TRIGGER EVENTS. Each of the following events
shall constitute an "ING TRIGGER EVENT" within the meaning of this ING Purchase
Agreement:

                  (a)      On any Settlement Date, the Default Ratio is greater
         than 1.5%; or

                  (b)      On any Settlement Date, the Delinquency Ratio is
         greater than 1.5%; or

                  (c)      On any Settlement Date, the ING 180 Day Delinquency
         Ratio is greater than 4.000%.

PROVIDED, THAT, an ING Trigger Event shall be deemed to be cured and no longer
continuing if both the Default Ratio and the Delinquency Ratio are less than or
equal to 1.5% and the ING 180 Day Delinquency Ratio is less than or equal to
4.000%, as computed on each of three consecutive Settlement Dates following an
ING Trigger Event, and no other ING Trigger Event or any ING Wind-Down Event has
occurred and no ING Amortization Date has occurred, and is continuing.

                  SECTION 2.07.  INCREASED COSTS, CAPITAL ADEQUACY.

                                       4
<Page>

                  (a) If, after the date hereof due to either (i) the
         introduction of or any change in or to the interpretation of any law or
         regulation by the governmental authority that promulgated or
         administers compliance with such law or regulation (other than laws or
         regulations with respect to income taxes) or (ii) the compliance with
         any guideline or request from any central bank or other governmental
         authority or similar agency (whether or not having the force of law),
         and ING's asset-supported financing business, any reserve or deposit or
         similar requirement shall be imposed, modified or deemed applicable or,
         any basis of taxation shall be changed or any other condition shall be
         imposed, and there shall be any increase in the cost to ING of making,
         funding or maintaining ING Receivables Interest Purchases or in the
         cost to ING of agreeing to make, fund or maintain ING Receivables
         Interest Purchases, then the Seller shall from time to time, upon
         demand by ING by the submission of the certificate described below, but
         subject to SECTION 5.01, pay to ING additional amounts sufficient to
         compensate ING for such increased cost. A certificate setting forth in
         reasonable detail the amount of such increased cost submitted to the
         Seller by ING (as applicable) shall be conclusive and binding for all
         purposes, absent manifest error.

                  (b) If ING determines that compliance with any law or
         regulation or any guideline or request or any written interpretation
         from any central bank or other governmental authority or similar agency
         (whether or not having the force of law) which is introduced,
         implemented or received by ING after the date hereof, affects or would
         affect capital adequacy or the amount of capital required or expected
         to be maintained by ING or any corporation controlling ING and that the
         amount of such capital is increased by or based upon this ING Purchase
         Agreement or has or would have the effect of reducing the rate of
         return on capital, then, upon demand by ING by the submission of the
         certificate described below, the Seller shall pay to ING, from time to
         time as specified by ING, additional amounts sufficient to compensate
         ING or such corporation in the light of such circumstances, to the
         extent that ING reasonably determines such increase in capital to be
         allocable to the ING Receivables Interest Purchases or the existence of
         this ING Purchase Agreement in respect of or on account of such events.
         A certificate setting forth in reasonable detail such amounts submitted
         to the Seller by ING shall be conclusive and binding for all purposes,
         absent manifest error.

                  (c) All amounts payable pursuant to this SECTION 2.07 shall be
         subject to the provisions of SECTION 5.01.

                  SECTION 2.08. TAXES. (a) All payments made by the Seller under
this ING Purchase Agreement shall be made free and clear of, and without
deduction or withholding for or on account of, any present or future taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any governmental
authority having taxing authority, excluding net income taxes and franchise
taxes (imposed in lieu of income taxes) imposed on ING, as a result of any
present or former connection between the jurisdiction of the government or
taxing authority imposing such tax or any political subdivision or taxing
authority thereof or therein and ING (excluding a connection arising solely from
ING having executed, delivered or performed its obligations or received a
payment under, or enforced, this ING Purchase Agreement) (all such non-excluded
taxes, levies, imposts, duties, charges, fees, deductions and withholdings being
hereinafter called "TAXES"). If

                                       5
<Page>

any Taxes are required to be withheld from any amounts payable by the Seller,
(i) the sum payable shall be increased as may be necessary so that, after making
all required deductions (including deductions applicable to additional sums
payable under this SECTION 2.08), ING (as applicable) receives an amount equal
to the sum it would have received had no such deductions been made, (ii) the
Seller shall make such deductions, and (iii) the Seller shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

                  (b) In addition, the Seller agrees to pay any present or
         future stamp or documentary taxes or any other excise or property
         taxes, charges or similar levies that arise from any payment made
         hereunder or from the execution, delivery or registration of, or
         otherwise with respect to, this ING Purchase Agreement (hereinafter
         "OTHER TAXES").

                  (c) The Seller will indemnify ING for the full amount of Taxes
         or Other Taxes (including, without limitation, any Taxes or Other Taxes
         imposed by any jurisdiction on amounts payable under this SECTION 2.08)
         paid by ING and any liability (including penalties, interest and
         expenses) arising therefrom or with respect thereto. Whenever any Taxes
         or other Taxes are payable by the Seller, as promptly as possible
         thereafter, the Seller shall send to ING a certified copy of an
         original official receipt received by the Seller showing payment
         thereof. If the Seller fails to pay any Taxes or other Taxes when due
         to the appropriate taxing authority or fails to remit to ING the
         required receipts or other required documentary evidence, the Seller
         shall indemnify ING for any incremental Taxes, interest or penalties
         that ING is legally required to pay as a result of any such failure.
         The agreements in this subsection shall survive the termination of this
         ING Purchase Agreement.

                  (d) All amounts payable pursuant to this SECTION 2.08 shall be
         subject to the provisions of SECTION 5.01.

                  SECTION 2.09. FEES. In further consideration of the ING
Receivables Interest Purchases to be made hereunder, the Seller agrees, subject
to SECTION 5.01, to pay to the ING all fees specified in the ING Fee Letter
dated as of August 5, 2002, which fees will be due and payable at the times and
in the manner set forth in such ING Fee Letter.

                  SECTION 2.10. (a) HEDGING REQUIREMENTS. At any time on or
after the Designated Termination Date, ING shall have the right to withdraw any
amounts on deposit in the Reserve Account and to enter into an interest rate cap
agreement (a "Hedge Agreement") with a financial institution (the "Swap
Counterparty") with a short term rating of at least "A-1+" from Standard &
Poor's Ratings Group (or "A-1" if such institution has a long term credit rating
of "AA" or higher) and "P-1" from Moody's Investors Services Inc., and otherwise
reasonably acceptable to ING. At any time, unless otherwise agreed to by ING in
its sole discretion, the Hedge Agreement must have a notional balance not less
than the amount of ING Capital outstanding and require such Counterparty to make
payments when the One-Month Libor rate exceeds 8.0% and shall otherwise be in
form and substance satisfactory to the Agent.

                                       6
<Page>

                  (b) RESERVE ACCOUNT. In order to fund the Hedge Agreement, ING
         shall establish an account (the "Reserve Account") for the benefit of
         the ING. On the Closing Date, ING shall cause to be deposited in the
         Reserve Account the amount of $262,968 from the proceeds of the initial
         ING Receivables Interest Purchase. The Reserve Account shall be
         established at the corporate trust department of a commercial bank
         reasonably satisfactory to ING, bearing the following designation: "ING
         Receivables Interest Reserve Account, for the benefit of ING Capital
         LLC". Until all of the ING Obligations have bee paid in full, ING shall
         possess all right, title and interest in all funds on deposit from time
         to time in the Reserve Account and in all proceeds thereof. Amounts on
         deposit in the Reserve Account shall be invested in any no-load money
         market fund rated (including money market funds managed or advised by
         ING) in the highest short-term rating category or equivalent highest
         long-term rating category by the Rating Agency. On each ING Receivables
         Interest Purchase Date and three Business Days prior to each Settlement
         Date, ING shall estimate the cost of purchasing a Hedge Agreement. If
         such cost multiplied by 1.25 (the "Required Reserve Amount") is greater
         than the amount then on deposit in the Reserve Account, ING shall
         deposit such difference (the "Required Deposit") from the proceeds of
         any ING Receivables Interest Purchase (if such date is an ING
         Receivables Interest Purchase Date) or from any amount available on the
         related Payment Date pursuant to clause (iii) of Section 2.04 hereof
         (in excess of any other ING Obligations due and payable on such Payment
         Date). Any amounts on deposit in the Reserve Account in excess of the
         Required Reserve Amount shall be withdrawn by ING and disbursed to the
         Seller. Upon the payment in full of all ING Obligations, ING shall
         withdraw any amounts on deposit in the Reserve Account and disburse
         such amounts to the Seller.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

                  SECTION 4.01. REPRESENTATIONS AND WARRANTIES OF THE SELLER.
The Seller represents and warrants to ING that:

                  (a) DUE INCORPORATION AND GOOD STANDING. The Seller is a
         limited liability company duly organized, validly existing and in good
         standing under the laws of its jurisdiction of incorporation. The
         Seller is duly qualified to do business as a foreign limited liability
         company and is in good standing in every jurisdiction in which the
         nature of its business requires it to be so qualified or where the
         ownership of its properties or the nature of its activities makes such
         qualification necessary, except where the failure to be

                                       9
<Page>

         so qualified would not materially adversely affect (i) the
         collectibility of the Purchased Assets, (ii) the collectibility of any
         Receivable, (iii) the business, properties, operations, prospects,
         profits or condition (financial or otherwise) of the Seller or (iv) the
         ability of the Seller to perform its obligations hereunder and under
         the other Facility Documents to which it is a party.

                  (b) Due Authorization and No Conflict. The execution, delivery
         and performance by the Seller of this ING Purchase Agreement and the
         transactions contemplated hereby and thereby are within the Seller's
         company powers, have been duly authorized by all necessary company
         action, do not contravene (i) the Seller's certificate of formation or
         limited liability company agreement, (ii) any law, rule or regulation
         applicable to the Seller, (iii) any contractual restriction contained
         in any indenture, loan or credit agreement, lease, mortgage, security
         agreement, bond, note, or other agreement or instrument binding on or
         affecting the Seller or its property or (iv) any order, writ, judgment,
         award, injunction or decree binding on or affecting the Seller or its
         property, and do not result in or require the creation of any Adverse
         Claim upon or with respect to any of its properties; and no transaction
         contemplated hereby requires compliance with any bulk sales act or
         similar law. This ING Purchase Agreement has been duly executed and
         delivered on behalf of the Seller.

                  (c) GOVERNMENTAL AND OTHER CONSENTS. No authorization,
         consent, approval or other action by, and no registration,
         qualification, designation, declaration, notice to or filing with, any
         governmental authority or other Person is or will be necessary in
         connection with the execution and delivery of this ING Purchase
         Agreement or any of the other documents contemplated hereby,
         consummation of the transactions herein or therein contemplated, or
         performance of or compliance with the terms and conditions hereof or
         thereof, to ensure the legality, validity or enforceability hereof or
         thereof.

                  (d) ENFORCEABILITY OF FACILITY DOCUMENTS. This ING Purchase
         Agreement has been duly and validly executed and delivered by the
         Seller and constitutes the legal, valid and binding obligation of the
         Seller enforceable in accordance with its respective terms, except as
         enforceability may be limited by bankruptcy, insolvency or similar laws
         relating to or affecting creditors' rights generally and by equitable
         principles.

                  (e) NO LITIGATION. There are no actions, suits or proceedings
         at law or in equity or by or before any governmental authority now
         pending or, to the knowledge of the Seller, threatened against or
         affecting the Seller or any property or rights of the Seller which
         purport to challenge the legality, validity or enforceability of this
         ING Purchase Agreement or which may materially impair the ability of
         the Seller to carry on business substantially as now being conducted or
         which may materially adversely affect the condition (financial or
         otherwise), operations or properties of the Seller.

                  (f) SOLVENCY. The Seller, both prior to and after giving
         effect to the initial ING Receivables Interest Purchase on the initial
         ING Receivables Interest Purchase Date, and after giving effect to each
         subsequent ING Receivables Interest Purchase, (i) is not "insolvent"
         (as such term is defined in Section 101(31)(A) of the Bankruptcy Code);
         (ii) is able to pay its debts as they become due; and (iii) does not
         have unreasonably small capital for

                                       10
<Page>

         the business in which it is engaged or for any business or transaction
         in which it is about to engage.

                              INTERCREDITOR ISSUES

                  SECTION 5.01.  PRIORITY OF PAYMENTS.

                  (a) Until the Collection Date, the ING Obligations are hereby,
         and shall continue to be, subject and subordinate in priority and
         payment to the Obligations, as set forth under SECTION 6.11 of the
         Triple-A Purchase Agreement, PROVIDED, however, that Triple-A and the
         Seller shall not amend SECTION 6.11 of the Triple-A Purchase Agreement
         to change the priority of payment of the ING Yield or other ING
         Obligations without the prior written consent of ING. Subject to the
         provisions set forth in SECTION 6.11 of the Triple-A Purchase
         Agreement, no payment shall be made with respect to any Collections on
         account of the ING Obligations, and ING shall not take or receive any
         Collections, directly or indirectly, in cash or other property or by
         setoff or in any other manner, including, without limitation, from or
         by way of collateral, payment of all or any of the ING Obligations,
         unless and until the Collection Date has occurred. Notwithstanding any
         provision in any other section of this ING Purchase Agreement to the
         contrary, ING hereby acknowledges and agrees that the Seller's payment
         obligations under this Agreement shall be without recourse to the
         Seller or the Purchased Assets except to the extent of funds or other
         proceeds thereof which may be allocated for payment thereof in
         accordance with the provisions of SECTION 6.11 of the Triple-A Purchase
         Agreement, and shall be without recourse to Triple-A or any of its
         assets except to the extent of the proceeds of the Purchased Assets
         which may be so allocated as set forth above. Unless and until such
         funds or other proceeds are available to pay any such amount, any ING
         Obligations shall not be payable until the earliest date on which
         proceedings of the type described in SECTION 5.01(c) could be initiated
         against the Seller pursuant to such Section.

                  (b) If ING shall receive any cash distributions in respect of
         any Collections in excess of what ING is entitled to pursuant to
         SECTION 6.11 of the Triple-A Purchase Agreement, ING shall hold the
         same in trust, as trustee, for the benefit of Triple-A and shall
         promptly deliver the same to or at the direction of Triple-A in
         precisely the form received (except for the endorsement or assignment
         thereof by ING) without recourse or warranty.

                  (c) Until ninety-one days after the Collection Date, ING
         hereby covenants and agrees that it will not take any Enforcement
         Action or, without the prior written consent of the Collateral Agent,
         otherwise acquiesce, petition or otherwise invoke or cause any other
         person to invoke the process of the United States of America, any state
         or other political subdivision thereof or any other jurisdiction, any
         entity exercising executive, legislative, judicial, regulatory or
         administrative functions of or pertaining to government for the purpose
         of commencing or sustaining a case against the Seller, under the
         Bankruptcy Code or any state Bankruptcy, insolvency or similar law or
         appointing a receiver, liquidator, assignee, trustee, custodian,
         sequestrator or other similar official of

                                       11
<Page>

         the Seller or all or any part of its property or assets or ordering the
         winding-up or liquidation of the affairs of the Seller. ING hereby
         appoints the Collateral Agent as its agent, and grants to the
         Collateral Agent an irrevocable power of attorney coupled with an
         interest, and its proxy, for the purpose of exercising any and all
         rights and taking any and all actions available to ING in connection
         with any case by or against the Seller under the Bankruptcy Code, or
         any state bankruptcy, insolvency or similar law, including without
         limitation, the right to vote to accept or reject a plan, to file a
         claim, to make any election under Section 1111(b) of the Bankruptcy
         Code with respect to the ING Receivable Interests and to file a motion
         to modify the automatic stay with respect to the Purchased Assets.

                  (d) ING covenants and agrees that it will not institute
         against Triple-A, or join any other Person in instituting against
         Triple-A, any Insolvency Proceeding under bankruptcy law or under any
         similar federal or state law.

                  SECTION 5.02. ING ACKNOWLEDGEMENT. (a) ING acknowledges that:
(i) ING has, independently and without reliance upon Triple-A, the
Administrative Agent, the Collateral Agent, the Surety or MBIA (collectively,
the "MBIA PARTIES"), and based on such documents and information as ING has
deemed appropriate, made ING's own credit analysis and decision to purchase the
ING Receivables Interests and ING accepts responsibility therefor; (ii) none of
the MBIA Parties has provided ING, and ING has not relied on or used in any
other way, any credit analysis of the ING Receivable Interests prepared by any
MBIA Party or an investigation or assessment of risk with respect to the ING
Receivable Interests prepared by any MBIA Party, and (iii) any information
provided to ING by any MBIA Party regarding the ING Receivable Interests is
provided without any warranty or representation, express or implied, as to its
accuracy or completeness and is subject to independent verification by ING.

                  (b) ING hereby acknowledges that no MBIA Party has made any
representations or warranties with respect to the ING Receivable Interests and
no MBIA Party shall have any responsibility for (i) the collectibility of the
ING Receivable Interests, (ii) the validity, enforceability or legal effect of
any of the ING Receivable Interests, (iii) the validity, sufficiency or
effectiveness of the lien created or to be created by the ING Receivable
Interests, or (iv) the financial condition of the Originator or the Seller. ING
assumes all risk or loss in connection with ING Receivable Interests, from the
failure or refusal of the Obligors to pay amounts due thereon, and defaults by
the Obligors to pay amounts due thereon, and defaults by the Obligors under the
underlying document or the enforceability of any of the underlying documents for
reasons other than gross negligence or willful misconduct by any MBIA Party. ING
hereby agrees to the appointment of CapMAC as Collateral Agent and
Administrative Agent under the Triple-A Purchase Agreement and further
acknowledges that (i) it has no right, title or interest in or to any of the
Surety Bonds or the rights and remedies of any MBIA Parties under the Insurance
Agreement; (ii) the Administrative Agent is solely an agent for Triple-A and has
no duties or obligations on behalf of Triple-A to ING except as otherwise
expressly provided herein; and (iii) the duties of the Collateral Agent set
forth in the Triple-A Purchase Agreement are limited as set forth therein.

                  SECTION 5.03. NO CREATION OF A PARTNERSHIP OR EXCLUSIVE
PURCHASE RIGHT. Nothing contained in this ING Purchase Agreement, and no action
taken pursuant hereto, shall

                                       12
<Page>

be deemed to constitute the arrangement between any MBIA Party and ING a
partnership, association, joint venture or other entity. Triple-A shall have no
obligation whatsoever to offer to ING the opportunity to purchase any ING
Receivable Interests. ING shall have no obligation whatsoever to purchase from
Triple-A any ING Receivable Interests.

                  SECTION 5.04. ASSIGNMENT OF RIGHTS. If the Collection Date has
occurred, but the Combined Collection Date has not occurred, Triple-A and the
Collateral Agent shall, at the request of ING, assign all of their rights in the
Triple-A Purchase Agreement and the other ING Facility Documents to ING. Such
assignment shall be without recourse, representation or warranty of any kind
other than that such assigned rights are not subject to any lien created by
Triple-A and/or the Collateral Agent and shall not include any rights or
remedies which relate solely to such parties' rights under the Surety Bonds
and/or the Insurance Agreement and ING shall agree, as a condition precedent to
such assignment, to release the MBIA Parties from any and all claims and
obligations of such parties arising in connection with the Triple-A Purchase
Agreement and/or this ING Purchase Agreement.

                                   ARTICLE VI

                          ADMINISTRATION AND COLLECTION

                  SECTION 6.01. DESIGNATION OF SERVICER. ING acknowledges and
agrees that the servicing, administering and collection of the Purchased
Receivables and the other Purchased Assets shall be conducted by the Servicer
designated by the Collateral Agent from time to time in accordance with SECTION
6.01 of the Triple-A Purchase Agreement.

                  SECTION 6.02. BACK-UP SERVICER. (a) The parties hereby appoint
BNY ASSET SOLUTIONS LLC, to act as Back-up Servicer with respect to the
Purchased Receivables and the other Purchased Assets.

                  (b) The Back-up Servicer, prior to becoming the successor
         Servicer, shall perform the following duties and obligations:

                  (i) On or prior to the fifth Business Day prior to each
         related Settlement Date, the Back-up Servicer shall review the summary
         and settlement report worksheets contained in the Settlement Report and
         will verify that the correct balances have been inserted based solely
         on the formulas contained in the Settlement Report. The Back-up
         Servicer shall not be required to review or verify any other
         information contained in the Settlement Report. The Back-up Servicer
         shall notify the Servicer in writing of any disagreements with the
         summary and settlement worksheet in the Settlement Date based on such
         review not later than the 2nd Business Day preceding the related
         Settlement Date to the extent such Settlement Report was received on or
         prior to the fifth Business Day prior to the related Settlement Date
         and as soon as practicable if it is received after such date.

                  (ii) If the Servicer disagrees with the notice provided under
         paragraph (i) above by the Back-up Servicer or if the Servicer has not
         reconciled such discrepancy, the Back-up Servicer agrees to confer with
         the Servicer to resolve such disagreement as promptly as practicable
         and shall settle such discrepancy with the Servicer if possible,

                                       13
<Page>

         and notify Triple-A, the Collateral Agent and ING in writing of the
         resolution thereof. The Servicer hereby agrees to cooperate at its own
         expense with the Back-up Servicer in reconciling any discrepancies
         therein. If after the notification provided under paragraph (i) above
         by the Back-up Servicer and prior to the related Settlement Date, such
         discrepancy is not resolved, the Back-up Servicer shall promptly notify
         in writing Triple-A, the Collateral Agent and ING of the continued
         existence of such discrepancy. Following receipt of such notice by the
         Triple-A, the Collateral Agent and ING, the Servicer shall deliver to
         the Back-up Servicer no later than two Business Days after such
         receipt, a certificate describing the nature and amount of such
         discrepancy and the actions the Servicer proposes to take with respect
         thereto.

                  (b) In the event that the Back-up Servicer shall become the
         Servicer under the Triple-A Purchase Agreement, the Back-up Servicer
         shall service and administer the Purchased Receivables and the other
         Purchased Assets and perform all of its duties thereunder in accordance
         with customary and usual procedures employed by institutions servicing
         commercial loans, which institutions are considered prudent by the
         Back-up Servicer, and in accordance with the Back-up Servicer's own
         customary practices, or if a higher standard, the highest degree of
         skill and attention that the Back-up Servicer exercises with respect to
         contracts comparable to the Contracts that the Back-up Servicer
         services for itself.

                  (c) The Back-up Servicer undertakes to perform only such
         duties and obligations as are specifically set forth in this Agreement
         and the Triple-A Purchase Agreement if the Back-up Servicer shall
         become the Servicer, it being expressly understood by all parties
         hereto that there are no implied duties or obligations of the Back-up
         Servicer hereunder. Without limiting the generality of the foregoing,
         the Back-up Servicer, except as expressly set forth herein, shall have
         no obligation to supervise, verify, monitor or administer the
         performance of the Servicer. The Back-up Servicer shall have no
         liability for any act or omission of the Servicer. Neither the Back-up
         Servicer nor any of its members, managers, officers, directors,
         employees or agents shall be liable, directly or indirectly, for any
         damages or expenses arising out of the services performed under this
         Agreement other than damages or expenses which result from the gross
         negligence or willful misconduct of it or them.

                  SECTION 6.03. BACK-UP SERVICING FEE. On each Settlement Date,
as full compensation for its servicing activities hereunder, the Back-up
Servicer shall be entitled to receive a fee (the "BACK-UP SERVICING FEE") in an
amount equal to 0.04% TIMES the Outstanding Balance of the Purchased Receivables
as of the last day of the prior calendar month TIMES one-twelfth, PROVIDED,
THAT, if the Back-up Servicer is also the Servicer under the Triple-A Purchase
Agreement, the Back-up Servicing Fee hereunder shall be deemed paid to the
extent of any payment by the Seller of the "Servicing Fee" specified and defined
in the Triple-A Purchase Agreement.

                  SECTION 6.04. INDEMNITY FOR LIABILITY CLAIMS. The Seller
hereby agrees to indemnify, defend and hold harmless the Back-up Servicer (which
shall include any of its directors, employees, officers and agents) against and
from any and all costs, expenses, losses, damages, claims and liabilities
arising out of or resulting from the Triple-A Purchase Agreement

                                       14

or this ING Purchase Agreement. The Back-up Servicer shall not be entitled to
any indemnification for any costs, expenses, losses, damages, claims and
liabilities arising out of or resulting from the willful misconduct or gross
negligence of the Back-up Servicer or its directors, employees, officers or
agents.

         Agreement; or

                  (b) The Seller shall fail to perform or observe any term,
         covenant or agreement contained in this ING Purchase Agreement and any
         such failure shall remain unremedied for five Business Days after
         written notice from ING; or

                  (c) As of the close of business on any Settlement Date or ING
         Receivables Interest Purchase Date, the ING Capital Limit shall be less
         than the aggregate outstanding ING Capital; or

                  (d) There shall have occurred, since the initial ING
         Receivables Interest Purchase Date, a material adverse change in the
         financial condition of the Seller or there shall have occurred any
         event which materially and adversely affects the collectibility or the
         Receivables generally or the ability of the Seller to perform hereunder
         or under the Triple-A Purchase Agreement; or

                  (e) ING Capital shall not have been reduced to zero pursuant
         to SECTION 2.03 (b) hereof within one Business Day of the consummation
         of any sale referred to in such section; or

                  (f) ING shall determine that continuation of this ING Purchase
         Agreement without exercise of remedies under Section 7.02 will impose a
         material adverse regulatory impact on ING.

                  SECTION 7.02. REMEDIES. Subject to ARTICLE V hereof, during
the existence of an ING Wind-Down Event, ING may, by written notice to the
Seller, take any or all of the following actions, at the same or different
times: (a) declare the ING Obligations to be immediately due and payable; (b)
pursue any other remedy under this ING Purchase Agreement and (c) exercise any
rights and remedies of a secured party under Article 9 of the UCC, which rights
and remedies shall be cumulative to those provided for under this ING Purchase
Agreement; PROVIDED, that, unless and until the Collection Date has occurred,
all payments from the Seller owing to ING hereunder shall be paid to the
Administrative Agent for distribution in accordance with SECTION 6.11 of the
Triple-A Purchase Agreement and ING's recourse to the Purchased Assets and any
other assets of the Seller shall be limited in accordance with ARTICLE V. From
and after the occurrence of the Collection Date and the assignment of rights
contemplated

                                       15

                                  ARTICLE VIII

                                  MISCELLANEOUS

                  SECTION 8.01. AMENDMENTS, ETC. No amendment to or waiver of
any provision of this ING Purchase Agreement, shall in any event be effective
unless the same shall be in writing and signed by the parties hereto. This ING
Purchase Agreement, together with the Triple-A Purchase Agreement, contains a
final and complete integration of all prior expressions by the parties hereto
with respect to the subject matter hereof and shall constitute the entire
agreement (together with the exhibits hereto) among the parties hereto with
respect to the subject matter hereof, superseding all prior oral or written
understandings.

                  SECTION 8.02. NOTICES, ETC. All notices and other
communications provided for hereunder shall, unless otherwise stated herein, be
in writing (including telex communication and communication by facsimile copy)
and mailed, telexed, transmitted or delivered, as to each party hereto, at its
address set forth under its name on the signature pages hereof or at such other
address as shall be designated by such party in a written notice to the other
parties hereto. All such notices and communications shall be effective, upon
receipt, or in the case of delivery by mail, five days after being deposited in
the mails, or, in the case of notice by telex, when telexed against receipt of
answer back, or in the case of notice by facsimile copy, when verbal
communication of receipt is obtained, in each case addressed as aforesaid,
except that notices and communications pursuant to Article II shall not be
effective until received.

                  SECTION 8.03. NO WAIVER; REMEDIES. No failure on the part of
ING, Triple-A, the Collateral Agent or the Administrative Agent to exercise, and
no delay in exercising, any right hereunder shall operate as a waiver thereof;
nor shall any single or partial exercise of any right hereunder preclude any
other or further exercise thereof or the exercise of any other right. The
remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

                  SECTION 8.04. BINDING EFFECT; ASSIGNABILITY. This ING Purchase
Agreement shall be binding upon and inure to the benefit of the Seller, ING,
Triple-A, the Collateral Agent and the Administrative Agent their respective
successors and permitted assigns (which successors of the Seller shall include a
trustee in bankruptcy). The Seller may not assign any of its rights and
obligations hereunder or any interest herein without the prior written consent
of ING, Triple-A and the Collateral Agent. Each of Triple-A and ING may assign
at any time its rights and obligations hereunder and interests herein to any
other Person without the consent of the Seller. Without limiting the foregoing,
the Seller and Triple-A hereby acknowledges that ING may sell or participate all
or an interest in the ING Receivables Interest to one or more parties. This ING
Purchase Agreement shall create and constitute the continuing obligations of the
parties hereto in accordance with its terms, and shall remain in full force and
effect until such time, after the Termination Date, as the Combined Collection
Date shall occur.

PURCHASE AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK, EXCEPT TO THE EXTENT THAT THE VALIDITY OR
PERFECTION OF THE INTERESTS OF THE COLLATERAL AGENT IN THE COLLATERAL OR
REMEDIES HEREUNDER OR THEREUNDER, IN RESPECT THEREOF, ARE GOVERNED BY THE LAWS
OF A JURISDICTION OTHER THAN THE STATE OF NEW YORK. THE SELLER HEREBY AGREES TO

OTHERWISE BETWEEN THE SELLER AND TRIPLE-A AND/OR THE ING ARISING OUT OF,

FOREGOING CONSENT TO JURISDICTION, THE SELLER HEREBY WAIVES ANY OBJECTION BASED
ON FORUM NON CONVENIENS, AND ANY OBJECTION TO VENUE OF ANY ACTION INSTITUTED
HEREUNDER AND CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS
DEEMED APPROPRIATE BY THE COURT. NOTHING IN THIS SECTION 8.05 SHALL AFFECT THE
RIGHT OF TRIPLE-A OR ING TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY
LAW OR AFFECT THE RIGHT OF TRIPLE-A OR ING TO BRING ANY ACTION OR PROCEEDING
AGAINST THE SELLER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION.

obligation under this ING Purchase Agreement shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability of
the remaining provisions or obligations, or of such provision or obligation in
any other jurisdiction, shall not in any way be affected or impaired thereby.
