•	replaces the definition of a Change of Control in the Credit Agreement so that the definition no longer (i) treats differently changes in the composition of the board of directors of the Company due to actual or threatened proxy solicitations or (ii) includes any acquisition by contract or otherwise by a person or two or more persons acting in concert that results in the acquisition of power to directly or indirectly exercise a controlling influence over the Company's management or policies or control over equity securities of the Company entitled to vote for member of the board of directors representing 25% or more of the combined voting power of such securities; and
•	increases the amount of senior note indebtedness that subsidiaries of the Company are permitted to guarantee under the Credit Agreement from $600,000,000 to $1,000,000,000.
