Documents as hereby amended are hereby ratified and confirmed in all
respects. Any reference to any Transaction Document in any other Transaction
Document shall be deemed to refer to this Amendment also, and any reference
in any Transaction Document to any other document or instrument amended,
renewed, extended or otherwise affected by this Amendment shall also refer to
such Amendment. The execution, delivery and effectiveness of this Amendment
shall not, except as expressly provided herein, operate as a waiver of any
right, power or remedy of the Purchaser under any Transaction Document nor
constitute a waiver of any provision of any Transaction Document.

         Section 7.2. SURVIVAL OF AGREEMENTS. All representations, warranties,
covenants and agreements of the Transaction Parties herein shall survive the
execution and delivery of this Amendment and the performance hereof, including

and agreements contained in any certificate or instrument delivered by any
Transaction Party hereunder or under any Transaction Document to the Purchaser

that it is a party to the Transaction Agreement, the Transmission Agreement
and the Receivables Purchase Agreement, and that it is bound by the terms and
conditions set forth therein to the same extent as if it had been an original
signatory to such Transaction Documents.

or in any other Transaction Document shall be in conflict with any term or
provision of the Assignment, the terms and provisions of the Transaction

Agreement and the Transmission Agreement, Cap Rock has agreed to execute and
