Pursuant to the Note Purchase Agreements, the Company will issue 2044 Notes in the aggregate principal amount of $125 million on the Settlement Date, subject to the satisfaction of customary closing conditions. The terms of the 2044 Notes are identical to the 2044 Notes issued by the Company in the exchange offer disclosed by the Company under Items 1.01, 2.03 and 3.02 of its Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on September 8, 2014 and incorporated herein by reference, except that the 2044 Notes to be issued on the Settlement Date will be restricted securities within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), and may not be transferred or resold except in a transaction exempt from or not subject to the registration requirements of the Securities Act and applicable state securities laws.

The foregoing description of the 2044 Notes does not purport to be complete and is qualified in its entirety by reference to a copy of the Indenture and the form of 2044 Notes filed with the SEC on September 8, 2014 as Exhibits 4.1 and 4.2, respectively, to the Company’s Current Report on Form 8-K and incorporated herein by reference.

On the Settlement Date, the Company will issue the 2044 Notes in the aggregate principal amount of $125 million for cash in the amount of $125.687 million (which amount equals the issue price of the 2044 Notes of 100.5% of the principal amount thereof plus accrued interest from September 5, 2014 to September 16, 2014), subject to the satisfaction of customary closing conditions. The conversion terms of the 2044 Notes are identical to the conversion terms of the 2044 Notes issued by the Company in the exchange offer disclosed by the Company under Items 1.01, 2.03 and 3.02 of its Current Report on Form 8-K filed with the SEC on September 8, 2014 and incorporated herein by reference.
