Item 1.01. Entry into a Material Definitive Agreement.

Purchase Agreement

On March 25, 2014, the Company entered into a purchase agreement (the “Purchase Agreement”) with J.P. Morgan Securities LLC and Deutsche Bank Securities Inc., as representatives of the several initial purchasers named therein (collectively, the “Initial Purchasers”), to issue and sell $350 million aggregate principal amount of 0.125% Convertible Senior Notes due 2019 (the “Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). In addition, the Company granted the Initial Purchasers a 30-day option to purchase up to an additional $52.5 million aggregate principal amount of the Notes on the same terms and conditions solely to cover over-allotments, if any. On March 26, 2014, the Initial Purchasers exercised their over-allotment option in full.

The Purchase Agreement includes customary representations, warranties and covenants by the Company and customary closing conditions. Under the terms of the Purchase Agreement, the Company has agreed to indemnify the Initial Purchasers against certain liabilities.

The description of the Purchase Agreement contained herein is qualified in its entirety by reference to the Purchase Agreement attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Convertible Note Hedge Transactions

In connection with the pricing of the Notes on March 25, 2014, and in connection with the Initial Purchasers’ exercise of their over-allotment option in full on March 26, 2014, the Company entered into privately-negotiated convertible note hedge transactions with respect to its common stock (the “Convertible Note Hedge Transactions”) with each of JPMorgan Chase Bank, National Association, London Branch, Deutsche Bank AG, London Branch, and Morgan Stanley & Co. International plc (collectively, the “Counterparties”). The Company will pay an aggregate amount of approximately $85.9 million to the Counterparties for the Convertible Note Hedge Transactions. The Convertible Note Hedge Transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the Notes, approximately 7.7 million shares of the Company’s common stock, which is the same number of shares underlying the Notes. The strike price of the Convertible Note Hedge Transactions is $52.1640, which corresponds to the initial conversion price of the Notes and are exercisable upon conversion of the Notes. The Convertible Note Hedge Transactions will expire upon the maturity of the Notes, unless earlier settled or terminated.

The Convertible Note Hedge Transactions are intended to reduce the potential dilution to the Company’s common stock upon conversion of the Notes and/or offset the cash payments in excess of the principal amount of converted Notes, as the case may be, in the event that the market price per share of the Company’s common stock, as measured under the Convertible Note Hedge Transactions, is greater than the strike price of the Convertible Note Hedge Transactions.

The Convertible Note Hedge Transactions are separate transactions entered into by the Company with each of the Counterparties and are not part of the terms of the Notes. Holders of the Notes will not have any rights with respect to the Convertible Note Hedge Transactions. The foregoing description of the Convertible Note Hedge Transactions is qualified in its entirety by the copy of the form of confirmation for the Convertible Note Hedge Transactions attached as Exhibit 10.2 to this Current Report on Form 8-K hereto and is incorporated herein by reference.

Warrant Transactions

In addition, concurrently with entering into the Convertible Note Hedge Transactions, on March 25, 2014 and on March 26, 2014, the Company separately entered into privately negotiated warrant transactions (the “Warrants”) with each of the Counterparties, whereby the Company sold to the Counterparties warrants to acquire, collectively, subject to customary anti-dilution adjustments and the net share settlement and cash settlement provisions under the Warrants, approximately 7.7 million shares of the Company’s common stock at an initial strike price of $81.1440 per share, which represents a premium of 110% over the last reported sale price of the Company’s common stock of $38.64 on March 25, 2014. The Company will receive aggregate proceeds of approximately $38.3 million from the sale of the Warrants to the Counterparties. The Warrants were sold in private placements to the Counterparties pursuant to the exemptions from the registration requirements of the Securities Act afforded by Section 4(a)(2) of the Securities Act.

If the market price per share of the Company’s common stock, as measured under the Warrants, exceeds the strike price of the Warrants, the Warrants will have a dilutive effect on the Company’s earnings per share, unless the Company elects, subject to certain conditions, to settle the Warrants in cash.

The Warrants are separate transactions entered into by the Company with each of the Counterparties and are not part of the terms of the Notes. Holders of the Notes will not have any rights with respect to the Warrants. The foregoing description of the Warrants is qualified in its entirety by the copy of the form of confirmation for the Warrants attached as Exhibit 10.3 to this Current Report on Form 8-K hereto and is incorporated herein by reference.
