1. ADMINISTRATION OF GOODS AND SERVICES CREDITS

The Buyer and the Seller agree to the following terms and conditions, for so long as there is any remaining outstanding balance of goods and services credits pursuant to

(i) Paragraph 2 of Amendment No. 13 of the Agreement or

(ii) Paragraph 6 of Amendment No. 13 of the Agreement or

(iii) Paragraph 3 of Amendment No. 13 of the Agreement.

Should the Buyer at any time have an outstanding trade balance for any goods and services purchased from the Seller, then, notwithstanding any provision in this Amendment or in the Agreement to the contrary, the Seller is hereby authorized by the Buyer to immediately deduct the amount of any trade invoice issued by the Seller and/or any of its Affiliates to the Buyer from the outstanding balance of such goods and services credits noted above. If within

thirty (30) calendar days of the relevant invoice date the Buyer in good faith disputes the validity of any invoice that has been paid by debiting the invoice amount from one or more of such goods and services credits, then the Seller will restore the amount of such disputed invoice to the relevant goods and services credit(s), pending final determination as to the validity of said invoice.

Notwithstanding the provisions of Paragraph 6 to Letter Agreement No. 1 of the Agreement, once the balance of credits referenced in (i), (ii) and (iii) above have been reduced to zero by virtue of debiting the dollar amount of outstanding trade invoices from such credits, the Buyer will pay the Seller all subsequent trade invoices in immediately available funds within thirty-five (35) calendar days from the relevant invoice date. However, the concession granted in the preceding sentence shall expire upon the earlier of (a) the Buyer’s emerging from the Chapter 11 Case as defined in Paragraph 6 below and (b) December 31, 2005. After application of all of the credits remaining after giving effect to the provisions of this paragraph 1, (i) should the Buyer fail to meet its obligation to pay trade invoices as herein provided, the Seller reserves the right to stop or otherwise suspend deliveries of goods and services and/or implement other credit terms, and (ii) should the Buyer’s trade payable balance at any time exceed the aggregate amount of US dollars – five hundred thousand (US$500,000), the Seller also has the right to stop or otherwise suspend deliveries of goods and services, provided, however, that if at any time Buyer’s trade payable balance exceeds US dollars - five hundred thousand (US$500,000), the Seller shall notify the Buyer and, so long as (a) no such excess has occurred within the immediately preceding 45-day period and (b) Buyer is not in default of any of its other trade payable obligations to the Seller, the Seller shall provide notice to the Buyer of such excess and shall allow the Buyer to make a payment within ten (10) calendar days of receipt of such notice in order to reduce such trade payable balance below US dollars – five hundred thousand (US$500,000).

2. The Buyer and its Affiliates shall waive any right it may have or may hereafter acquire to assert any claim under Section 547 of the Bankruptcy Code or otherwise that any payment made by the Buyer and/or its Affiliates by deduction of any goods and services credits available to the Buyer under the Agreement constitutes a preferential payment or otherwise ought to be avoided or repaid by the Seller and/or any of its Affiliates to either the Buyer or its Affiliates, to any trustee or other representative in bankruptcy appointed for the Buyer and/or its Affiliates or the Court.

3. CREDIT REDUCTION

3.1 The Buyer hereby requests and the Seller agrees to reduce the outstanding balance of the credit described in Paragraph 5.4.2 of Letter Agreement No. 7 to the Agreement, as amended in Paragraph 12 of Letter Agreement No. 1 to Amendment No. 12 to the Agreement, by an amount equal to US dollars – one million five hundred twenty-eight thousand (US$1,528,000).

A motion for such approval shall be submitted by the Buyer as soon as practicable following the execution hereof and in any event within the period required in order that such motion may be heard at the Omnibus Hearing currently scheduled for January 27, 2005.
