as follows:

“Operating Committee. The Principal Investor Groups will create an operating

provide advice to the Board, when requested to do so, with respect to any
matter, including acquisitions, dispositions, financings and operating
performance. Each Principal Investor Group shall be permitted to designate one
representative (who shall not be a director of the Company) to participate on
the Operating Committee, and shall be permitted to remove and replace such
designee from time to time, provided that a Principal Investor Group’s designee
shall be automatically removed (and not replaced) at such time as such Principal
Investor Group ceases to be a Principal Investor Group in accordance with the

direct and indirect subsidiaries to present to the Operating Committee for its
review, any transaction of a sort otherwise described in any of Section 2.3.1

2. Limited Amendment. Except as specifically amended by the Amendment, the

4. Governing Law. This Amendment shall be governed by and construed in
accordance with the domestic substantive laws of the State of Delaware without
giving effect to any choice or conflict of laws provision or rule that would
cause the application of the domestic substantive laws of any other
