 or otherwise),                                                                                                   |

then, solely for purposes of such conversion, we will, without duplication, give effect to such adjustment on such conversion date (in the case of physical settlement) or such VWAP trading day (in the case of combination settlement). In such case, if the date we are otherwise required to deliver the consideration due upon such conversion is before the first date on which the amount of such adjustment can be determined, then we will delay the settlement of such conversion until the second business day after such first date. Notwithstanding anything to the contrary, if:

| • |     | a conversion rate adjustment for any dividend or distribution becomes effective on any ex-dividend date pursuant to the provisions described above under the caption “—Conversion Rate Adjustments—Generally”; |

| • |     | a note is to be converted pursuant to physical settlement or combination settlement; |

| • |     | the conversion date for such conversion (in the case of physical settlement) or any VWAP trading day in the                                                       
 observation period for such conversion (in the case of combination settlement) occurs on or after such ex-dividend date and on or before the related record date; |

| • |     | the consideration due upon such conversion includes any whole shares of our common stock (in the case of physical                                                                                                                                       
 settlement) or due in respect of such VWAP trading day includes any whole or fractional shares of our common stock (in the case of combination settlement), in each case based on a conversion rate that is adjusted for such dividend or distribution; 
 and                                                                                                                                                                                                                                                     |

| • |     | such shares would be entitled to participate in such dividend or distribution, |

then:

| • |     | in the case of physical settlement, such conversion rate adjustment will not be given effect for such conversion                                                                                                                                      
 and the shares of our common stock issuable upon such conversion based on such unadjusted conversion rate will not be entitled to participate in such dividend or distribution, but there will be added, to the consideration otherwise due upon such 
 conversion, the same kind and amount of consideration that would have been delivered in such dividend or distribution with respect to such shares had such shares been entitled to participate in such dividend or distribution; and                  |

| • |     | in the case of combination settlement, the conversion rate adjustment relating to such ex-dividend date will be made for such conversion in respect of such VWAP trading day, but the shares of our common
