This Amendment No. 8 reflects the agreement between the Parties with respect to upgrading the Equipment and Software in Owner’s Amendment No. 8 Existing Markets and Owner’s New Markets. “Amendment No. 8 Existing Markets” means all Markets previously awarded to Vendor and for which Owner’s System operates with Vendor’s Products as of the Amendment No. 8 Effective Date. “New Markets” means any Market of Owner, whether existing now or in the future, other than the Amendment No. 8 Existing Markets.

Owner commits to purchase Products and Services from Vendor over a three-year period (effective from October 1, 2005 to September 30, 2008, referred to herein as the “Amendment No. 8 Purchase Commitment Term”) totaling not less than [$119,000,000] before potential credits to be earned by Owner pursuant to Section 3.5 below (the “Amendment No. 8 Purchase Commitment”).

All purchases by any Affiliate of Owner under a separate Affiliate Contract with Vendor shall be credited toward the Amendment No. 8 Purchase Commitment, except to the extent that any such purchases are made toward satisfaction of any separate purchase commitment contained in such Affiliate Contract.

Owner shall not have failed to satisfy the Amendment No. 8 Purchase Commitment to the extent of any of the following: (i) Vendor’s rejection of any purchase order, where such Purchase Order is in compliance with the terms and conditions of the applicable contract (i.e., this Contract or an Affiliate’s Contract with Vendor), provided that Owner or the Affiliate, as applicable, is not in arrears in its payments under such contract and is not in material breach of such contract; (ii) Vendor’s failure, which failure shall be solely due to
