Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Indenture. This notice is qualified in its entirety by the terms and conditions outlined in the Indenture.

A Note shall be deemed to have been converted immediately prior to the close of business on the date that the Holder has complied with the requirements set forth in Section 14.02(b) of the Indenture, which provides that before any Holder of a Note shall be entitled to convert a Note, such Holder shall: in the case of a Global Note, comply with the procedures of the Depositary Trust Company in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) of the Indenture.

Pursuant to Section 14.01(a) of the Indenture, the Conversion Rate shall be 114.4885 shares of Common Stock per $1,000 principal amount of Notes.
