(12) The first full paragraph on page 48 of the Offer to Exchange is hereby amended to add the following sentence prior to the final sentence of the paragraph: At our option, we may issue one share of our common stock instead of paying cash in lieu of fractional shares.

We shall deliver the foregoing on the third trading day immediately following the last day of the related observation period. The "observation period" with respect to any New Note converted means the 15 consecutive trading-day period beginning on and including the third trading day after a holder delivers a conversion notice to the conversion agent or, if the we have elected to pay the net share amount in cash, the trading day after the last day of the conversion retraction period. The "daily settlement amount," for each of the 15 trading days during the observation period, shall consist of: o cash (the "daily cash amount") equal to the lesser of $66.67 and the daily conversion value relating to such day; and o if such daily conversion value exceeds $66.67, a number of shares of common stock with a value (the "daily share amount") equal to (A) the difference between such daily conversion value and $66.67, divided by (B) the daily VWAP for such day. Instead of delivering shares of common stock in satisfaction of our obligation to deliver the net share amount upon conversion of Notes, we may elect to deliver an additional amount of cash. The amount shall be equal to the net share amount. 5 We will inform the holders through the trustee if we choose to satisfy our obligation to deliver the net share amount upon conversion with additional cash no later than two trading days following the conversion date. If we do not give any notice within the time periods described as to how we intend to settle, we will satisfy our obligation to deliver the net share amount only in shares of common stock (and cash in lieu of fractional shares). We will treat in the same manner all holders converting on the same trading day. Subject to the foregoing, we will not, however, have any obligation to settle our conversion obligations arising on different trading days in the same manner. For holders converting on any trading day, we may choose to settle the net share amount in cash and shares of common stock only and for holders converting on another trading day, choose to settle exclusively in cash. If we elect to satisfy any portion of our obligation to deliver the net share amount in cash (other than cash in lieu of fractional shares), holders may retract their conversion notice at any time during the three trading day period beginning on the trading day after we have notified the trustee of our method of settlement. The "daily conversion value" means, for each of the 15 consecutive trading days during the observation period, one-fifteenth (1/15) of the product of (1) conversion rate on such day and (2) the daily VWAP of common stock (or the value of the securities into which common stock has been converted) for such day. The "daily VWAP" for the common stock means, for each of the 15 consecutive trading days during the observation period, the per share volume-weighted average price as displayed under the heading "Bloomberg VWAP" on Bloomberg page IART [EQUITY] AQR in respect of the period from 9:30 a.m. to 4:00 p.m. (New York City time) on such trading day (or if such volume-weighted average price is unavailable, the market value of one share of common stock on such trading day as the board of directors determines in good faith using a volume-weighted method, which determination shall be conclusive). (14) The last sentence in the paragraph under the heading "Calculations in Respect of New Notes" on page 56 of the Offer to Exchange is hereby amended and restated in its entirety as follows: We will make all these calculations in good faith and, absent manifest error, our calculations will be final and binding on holders of New Notes, subject to such holder's disputing such calculation in a court of competent jurisdiction.
