CALCULATION OF FILING FEE



Transaction Valuation(1)		Amount of Filing Fee(2)
$2,529,313,507.44		$289,859.33

(2)	The amount of the filing fee was calculated in accordance with Rule 0-11 of the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory #3 for fiscal year 2012, issued September 29, 2011, by multiplying the transaction value by 0.0001146.

Item 11

(a) Agreements, Regulatory Requirements and Legal Proceedings. Item 11(a) of the Schedule TO is hereby amended and supplemented by adding the following paragraph immediately after the last paragraph of the sub-section captioned “Stockholder Litigation.”

“On February 3, 2012, the attorneys for the plaintiffs in the Consolidated Delaware Action sent a letter to the Court of Chancery of the State of Delaware stating that the Company’s amended Schedule 14D-9 mooted their allegations that the Schedule 14D-9 was materially misleading or contained omissions of material fact. In light of this, the attorneys for the plaintiffs informed the Court of Chancery that they were withdrawing their motion for a preliminary injunction and requested that the Court of Chancery cancel the scheduled February 6 hearing. Accordingly, the Court of Chancery agreed to cancel the February 6 preliminary injunction hearing.”

SIGNATURE

After due inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
