As a result of such damage, the Parties desire to revise the Empress Target Closing Date in accordance with the terms of this Amendment and to enter into the agreements referenced in the following provisions of this Amendment.

NOW THEREFORE, in and for the terms and provisions hereof and other good and valuable consideration, the Parties agree as follows:

1. Definitions. Article I is amended as follows:

(a) The definition of “Empress Target Closing Date” is deleted in its entirety and the following is substituted in lieu thereof:

“Empress Target Closing Date” shall mean the first Business Day of the month following the month in which the Empress System Election Date occurs.

(b) The following definitions are added to Article I:

“Empress System Election Date” shall have the meaning set forth in Section 7.16(b)(ii).

“Expanded Capabilities” shall have the meaning set forth in Section 7.16(b)(i).

“Restoration Activities” shall have the meaning set forth in Section 7.16(b)(i).

“Restoration Period” shall have the meaning set forth in Section 7.16(b)(iii)(C).

“Windstorm” shall have the meaning set forth in Section 7.16(a).

2. Section 7.16(a). Clause (iv) of Section 7.16(a) is amended by inserting the phrase:

“(excluding any Material Adverse Effect resulting from the windstorm that struck the Empress System on June 21, 2005 (the “Windstorm”))”

after the first reference to “Material Adverse Effect” contained therein.

3. Sections 7.16(b) and (c). Section 7.16(b) is amended by renumbering the same a Section 7.16(c) (and any references in the Agreement to such 7.16(b) shall be deemed to refer to such section as renumbered to be Section 7.16(c)) and by inserting the following as the new Section 7.16(b):

(b) (i) COP has already commenced and shall continue to pursue expeditiously to completion (subject to clause (ii) below) the design, repair and replacement of components of the Empress System damaged by the Windstorm and the return of the Empress System to its normal operations and capabilities as they existed prior to the Windstorm (the “Restoration Activities”). The Restoration Activities include removing the damaged cooling tower, installing temporary coolers and removing such temporary coolers once the permanent new cooling tower is installed and fully operational, and constructing and installing a permanent new cooling tower and related facilities. COP shall consult with Duke regarding the Restoration Activities and shall consider Duke’s views in formulating and executing COP’s plan for the conduct of the Restoration Activities, including any improvement or expansion of the cooling capabilities of such new permanent cooling tower and related facilities (the “Expanded Capabilities”).

(ii) The earlier of (i) the date three Business Days after COP provides Duke written notice that the temporary coolers have been installed and the Empress System has been returned to, and has been operating for a period of 5 consecutive days at, its normal operations and capabilities as they existed prior to the Windstorm or (ii) July 31, 2005, is herein referred to as the “Empress System Election Date”.

(iii) If the Empress Closing occurs, then:

(A) Duke will take over from COP the Restoration Activities as of the Empress Closing Date and COP shall take such actions as are reasonably necessary to transition the Restoration Activities to Duke as of the Empress Closing Date.
