PP =        AUB x PPP

where:

PP =                    the aggregate Purchase Price for the Purchased Receivables and Related Purchased Assets to be purchased from such Seller on such day.

AUB =                the Aggregate Unpaid Balance of the Purchased Receivables that are to be purchased from such Seller on such day.  “Aggregate Unpaid Balance” shall mean the sum of the Unpaid Balance of each Receivable to be purchased from such Seller on such day, calculated at the time of the Receivable’s sale to Buyer.

PPP =      100% - (LP + PD + DR)

where:

PPP =                  the Purchase Price Percentage in effect during such Distribution Period.

ARTICLE III

SECTION 3.1                 Purchase Price Payments.  (a) On the Business Day following each day on which any Receivables and Related Purchased Assets are purchased by Buyer pursuant to Article I on the terms and subject to the conditions of this Agreement, Buyer shall pay to the Sellers the Purchase Price (as adjusted in accordance with this Section 3.1) for the Receivables and Related Purchased Assets purchased on such day by Buyer from the Sellers by:  (i) making a cash payment to the Sellers to the extent that Buyer has cash available to make the payment pursuant to Section 3.3 and (ii) if the Purchase Price to be paid for the Receivables and Related Assets of any Seller exceeds the amount of any cash payment for the account of such Seller pursuant to clause (i), then by increasing the principal amount outstanding under the relevant Buyer Notes by the amount of the excess or otherwise elects.

(b)           On the last day of each Calendar Cycle, the “Noncomplying Receivables Adjustment” for each Seller shall be equal to the difference (whether the difference is positive or negative) between (i) the aggregate Seller Noncomplying Receivables Adjustments in respect of such Seller, if any, for the immediately preceding Calendar Cycle, as shown in the Periodic Report for such Calendar Cycle, as such amount is determined pursuant to Section 3.5 minus (ii) the amount of the payments (if any) that Buyer shall have received during such Calendar Cycle from such Seller on account of any Seller Noncomplying Receivables that had been the subject of an earlier Seller Noncomplying Receivables Adjustment. If the Noncomplying Receivables Adjustment for any Seller is positive for any Calendar Cycle, Buyer shall reduce the Purchase Price payable to such Seller on such day pursuant to subsection (a) above by the amount of the Noncomplying Receivables Adjustment. If instead the Noncomplying  Receivables Adjustment for any Seller is negative for any Calendar Cycle, Buyer shall increase the Purchase Price payable to such Seller pursuant to subsection (a) above on such day by the amount of the Noncomplying Receivables Adjustment.

(c)           If for any Calendar Cycle the Seller Noncomplying Receivables Adjustments in respect of any Seller (as determined pursuant to Section 3.5), less any amounts in clause (b)(ii) relating to the Receivables of such Seller, exceeds the Purchase Price payable by Buyer to such Seller pursuant to subsection (a) above on such day, or it such day falls on or after the Purchase Termination Date, then the principal amount of such Seller’s Buyer Note shall be reduced automatically by the amount of such excess.

6

(d)           If, on any day prior to the Purchase Termination Date, the principal amount of a Seller’s Buyer Note is zero and such Seller is not a Terminating Seller, then the amount of the excess of the Seller Noncomplying Receivables Adjustments in respect of such Seller (as determined pursuant to Section 3.5), less any amounts in clause (b)(ii) relating to the Receivables of such Seller on such day over the Purchase Price payable by Buyer to such Seller on such day pursuant to subsection (a) above (the “Purchase Price Credit”) shall be credited against the Purchase Price payable by Buyer for subsequent Purchases by Buyer of Receivables and Related Assets from such Seller. If any such Purchase Price Credit has not been fully applied on or prior to the tenth Business Day (or a mutually agreed upon earlier day) after the creation of such Purchase Price Credit, then, on the Business Day that follows the end of the tenth Business Day (or shorter) period, such Seller shall pay to Buyer in cash the remaining unapplied amount of the Purchase Price Credit.

(e)           If, on any day on or after the Purchase Termination Date, or, with respect to any Seller, the date such Seller becomes a Terminating Seller, the principal amount of any Seller’s Buyer Note has been reduced to zero, an amount equal to the Seller Noncomplying Receivables Adjustments, if any, in respect of such Seller (as determined pursuant to Section 3.5), less any amounts in clause (b)(ii) relating to such Seller’s Receivables, shall be paid by such Seller to Buyer in cash on the next succeeding Business Day.

(f)            If, on any day, the amounts, if any, relating to any Seller’s Receivables pursuant to clause (b)(ii) above exceeds the Seller Noncomplying Receivables Adjustments, if any, in respect of such Seller (as determined pursuant to Section 3.5) for such day, then Buyer shall either (i) pay Initial Collection Agent (for the account of such Seller) in cash the amount of such excess, or (ii) if Buyer does not have sufficient cash to pay such amount in full, increase the principal amount of such Seller’s Buyer Note by the amount of such excess that is not paid in cash to Initial Collection Agent.

(g)           Amounts received by the Initial Collection Agent pursuant to this Section 3.1 shall be allocated among the Sellers in accordance with Section 3.3, and the Seller Noncomplying Receivables Adjustments in respect of each such Seller (as determined pursuant to Section 3.5). The Initial Collection Agent shall maintain a bookkeeping account (the “Seller Account”) for purposes of tracking:

(i)            the Purchase Price payable to each Seller in respect of Receivables sold by it to Buyer (including the extent to which cash and non-cash payments made by Buyer should be allocated to each Seller),

(ii)           the extent to which such Purchase Price should be reduced on account of such Seller’s Seller Noncomplying Receivables Adjustments (including any allocation of a Purchase Price Credit),

(iii)          the extent to which payments (whether cash or non-cash) by Buyer in respect of a negative Noncomplying Receivables Adjustment should be allocated to each Seller, and

7

(iv)          cash payments made to and by each Seller in respect of the items described above.

The Initial Collection Agent shall maintain sufficient records with respect to the Seller Account such that, on any day, it would be able to calculate each of the items set forth above.

Buyer may prepay all or part of the outstanding balance of any Buyer Note from time to time without any premium or penalty, unless the prepayment would result in a default in Buyer’s payment of any other amount required to be paid by it under any Transaction Document.

(b)           The Initial Collection Agent (or its designee) shall hold all Buyer Notes for the benefit of the Sellers and shall make all appropriate recordkeeping entries with respect to the Buyer Notes or otherwise to reflect the payments on and adjustment of the Buyer Notes.

SECTION 3.3                 Application of Collections and Other Funds.  If, on any day, Buyer (or, the Initial Collection Agent, on behalf of the Buyer) receives (i) proceeds of transfers pursuant to the Receivables Sale Agreement or (ii) Purchaser Collections and/or Seller Collections, in each case pursuant to the Receivables Sale Agreement, Buyer shall apply the funds as follows:

(a)           first, to pay its existing expenses and to set aside funds for the payment of expenses that are then accrued (in each case to the extent such expenses are permitted to exist under the Receivables Sale Agreement),

(b)           second, to pay the Purchase Price pursuant to Section 3.1 for Receivables and Related Assets purchased by Buyer from the Sellers on such day, such payment to be

8

(c)           third, to pay the following amounts:  (A) to pay amounts owed by Buyer to the Sellers under the Buyer Notes on a pro rata basis based on the then unpaid principal balance of the Buyer Notes, (B) to pay amounts to the Sellers owed pursuant to Section 3.1(f) on a pro rata basis based on the then unpaid amounts owing to all Sellers pursuant to Section 3.1(f), or (C) to declare and pay dividends to the Parent to the extent permitted by law.

SECTION 3.4                 Servicing of Receivables and Related Assets.  Consistent with Buyer’s ownership of the Receivables and the Related Assets, as between the parties to this Agreement, Buyer shall have the sole right to service, administer and collect the Receivables and to assign and/or delegate the right to others. Without limiting the generality of Section 10.11, each Seller hereby acknowledges and agrees that Buyer shall assign to the Agent on behalf of the Purchasers the rights and interests of Buyer hereunder and agrees to cooperate fully with the Initial Collection Agent (and any successor thereto appointed in accordance with the Receivables Sale Agreement), the Agent, the Purchaser Agents and the Purchasers in the exercise of such rights.

SECTION 3.5                 Adjustments for Noncomplying Receivables.  If at any time any of the Buyer, Initial Collection Agent, the Agent, any of the Purchaser Agents, any of the Purchasers, or a Seller shall determine that (i) any Receivable has been reduced as the result of any dispute, claim, offset or defense (other than discharge in bankruptcy of the Obligor) of the Obligor to the payment of any Receivable, or any other claim resulting from the sale or lease of goods or the rendering of services related to such Receivable or the furnishing or failure to furnish any goods or services or other similar claim or defense not arising from the financial inability of any Obligor to pay undisputed indebtedness, (ii) any of the representations and warranties made by the related Seller in Section 5.1 with respect to any Receivable originated by such Seller was not true on the date of the purchase thereof by Buyer or the date of contribution thereof to Buyer, or (iii) without duplication of the amounts set forth in clause (i) and (ii), any Notice of Difference has been delivered with respect to any Receivable transferred by such Seller, then, in each such case, any Purchase Price payable to such Seller shall be reduced by an amount equal to (x) in the case of clause (i) or clause (iii), the amount of such whole or partial reduction and (y) in the case of clause (ii), the Unpaid Balance of each such affected Receivable (the sum of the amounts in clauses (x) and (y) for such Seller on any day being called the “Seller Noncomplying Receivables Adjustment” for such Seller for such day), and such Seller Noncomplying Receivables Adjustment shall be settled in the manner provided for in Section 3.1.

SECTION 3.6                 Payments and Computations Etc.  (a) All amounts to be paid by a Seller to Buyer hereunder shall be paid in accordance with the terms hereof no later than 1:00 p.m. New York City time, on the day when due in Dollars in immediately available funds to an account that Buyer shall from time to time specify in writing. Payments received by Buyer after such time shall be decried to have been received on the next Business Day. In the event that any payment becomes due on a day that is not a Business Day, then the payment shall be made on the next Business Day. Each Seller shall, to the extent permitted by law, pay to Buyer on demand, interest on all amounts not paid when due hereunder at 2% per annum above the interest rate on the applicable Buyer Note in effect on the date the payment was due; provided, however, that the

Payments received by initial Collection Agent after such time shall be deemed to have been received on the next Business Day. Initial Collection Agent shall promptly remit payments received by it in immediately available funds to such account as the applicable Seller shall from time to time specify in writing.  In the event that any payment becomes due on a day that is not a Business Day, then such payment shall be made on the next Business Day.

(a)           In the event of any Bankruptcy Proceeding, the Senior Interests shall first be paid and performed in full and in cash before the Holder shall be entitled to receive and to retain any payment or distribution in respect of the Junior Liabilities. In order to implement the foregoing: (i) all payments and distributions of any kind or character in respect of the Junior Liabilities to which the Holder would be entitled except for this clause (a) shall be made directly to the Agent (for the benefit of itself and the Purchasers), and (ii) if a Bankruptcy Proceeding has been commenced, the Holder shall promptly file a claim or claims, in the form required in such Bankruptcy Proceeding, for the full outstanding amount of the Junior Liabilities, and shall use commercially reasonable efforts to cause said claim or claims to be approved and all payments and other distributions in respect thereof to be made directly to the Agent (for the benefit of itself and the Purchasers) until the Senior Interests shall have been paid and performed in full and in cash.

(c)           Upon the final indefeasible payment in full and in cash of all Senior Interests, the Holder shall be subrogated to the rights of the Agent and the Purchasers to receive payments or distributions from Buyer that are applicable to the Senior Interests until the Junior Liabilities are paid in full.

(d)           These Subordination Provisions are intended solely for the purpose of defining the relative rights of the Holder, on the one hand, and the Agent and the Purchasers on the other hand. Nothing contained in these Subordination Provisions or elsewhere in this Note is intended to or shall impair, as between Buyer, its creditors (other than the Agent and the Purchasers) and the Holder, Buyer’s obligation, which is unconditional and absolute, to pay the Junior Liabilities as and when the same shall become due and payable in accordance with the terms hereof and of the Agreement or to effect the relative rights of the Holder and creditors of Buyer (other than the Agent and the Purchasers).

3

an equity interest in Buyer, unless, in the case of each of clauses (i) and (ii), the Holder shall have received the prior written consent of the Instructing Group in each case.

(f)            The Holder shall not commence, or join with any other Person in commencing, any proceeding of the type referred to in the definition of Bankruptcy Event with respect to Buyer until at least one year and one day shall have passed after the Senior Interests shall have been finally paid and performed in full and in cash; provided, however, that the Holder shall at all times have the right to file any claim in or otherwise take any action with respect to any insolvency proceeding instituted against Buyer by any Person other than the Holder (provided that no such action may be taken by the Holder until such proceeding has continued undismissed, unstayed and in effect for a period of 10 days).

(g)           If, at any time, any payment (in whole or in part) made with respect to any Receivable is rescinded or must be restored or returned by the Agent or a Purchaser (whether in connection with any Bankruptcy Proceedings or otherwise), these Subordination Provisions shall continue to be effective or shall be reinstated, as the case may be, as though such payment had not been made.

(h)           Each of the Agent and the Purchasers may, from time to time, in its sole discretion, without notice to the Holder, and without waiving any of its rights under these Subordination Provisions, take any or all of the following actions: (i) retain or obtain an interest in any property to secure any of the Senior Interests, (ii) retain or obtain the primary or secondary obligations of any other obligor or obligors with respect to any of the Senior Interests, (iii) extend or renew for one or more periods (whether or not longer than the original period), alter, increase or exchange any of the Senior Interests, or release or compromise any obligation of any nature with respect to any of the Senior Interests, (iv) amend, supplement, amend and restate, or otherwise modify any Transaction Document to which it is a party, and (v) release its security interest in, or surrender, release or permit any substitution or exchange for all or any part of any rights or property securing any of the Senior Interests, or extend or renew for one or more periods (whether or not longer than the original period), or release, compromise, alter or exchange any obligations of any nature of any obligor with respect to any such rights or property.

(i)            The Holder hereby waives: (i) notice of` acceptance of these Subordination Provisions by the Agent or any of the Purchasers, (ii) notice of the existence, creation, non-payment or non-performance of all or any of the Senior Interests, and (iii) all diligence in enforcement, collection or protection of, or realization upon, the Senior Interests, or any thereof, or any security therefor.

(j)            These Subordination Provisions constitute a continuing, offer from Buyer to all Persons who become the holders of, or who continue to hold, Senior Interests, and these Subordination Provisions are made for the benefit of the Agent and the Purchasers, and the Agent may proceed to enforce such provisions on behalf of each of such Persons.

8.             General.  No failure or delay on the part of the Holder in exercising any power or right hereunder shall operate as a waiver thereof nor shall any single or partial exercise of any such

4

power or right preclude any other or further exercise thereof or the exercise of any other power or right. No amendment, modification or waiver of, or consent with respect to, any provision of this Note shall in any event be effective unless (a) the same shall be in writing and signed and delivered by Buyer and the Seller, and (b) all consents required for such actions under the Transaction Documents shall have been received by the appropriate Persons.
