The Borrower shall not permit its ratio of Consolidated Indebtedness to Consolidated EBITDA in each case for the four full fiscal quarters most recently ended (including, without limitation, the four fiscal quarter period ending December 31, 2003) to exceed:

5.25 to 1.00 as of December 31, 2003 and as of March 31, 2004; and

4.75 to 1.00 as of June 30, 2004 and as of the last day of any fiscal quarter of the Borrower thereafter.

For purposes of calculating such ratio the Project Finance Subsidiaries shall be disregarded. For purposes of this Section 6.07(b), if during any period of four fiscal quarters the Borrower or any Subsidiary acquires any Person (or any interest in any Person) or all or substantially all of the assets of any Person, the EBITDA attributable to such assets or an amount equal to the percentage of ownership of the Borrower or a Subsidiary, as the case may be, in such Person times the EBITDA of such Person, for such period determined on a pro forma basis (which determination, in each case, shall be subject to approval of the Administrative Agent, not to be unreasonably withheld) may be included as Consolidated EBITDA for such period as if such acquisition occurred on the first day of such four fiscal quarter period; provided that during the portion of such period that follows such acquisition, the computation in respect of the EBITDA of such Person or such assets, as the case may be, shall be made on the basis of actual (rather than pro forma) results.
