To the extent that any of the selling security holders identified above are broker-dealers, they may be deemed to be, under interpretations of the SEC, “underwriters” within the meaning of the Securities Act.

With respect to selling security holders that are affiliates of broker-dealers, based on information provided by the selling security holders, we believe that such entities acquired their notes or shares of common stock issuable upon conversion of the notes in the ordinary course of business and, at the time of the purchase of the notes or shares of common stock issuable upon conversion of the notes, such selling security holders had no agreements, understandings or arrangements, directly or indirectly, with any person to distribute the notes or shares of common stock issuable upon conversion of the notes.

Based upon information provided by the selling security holders, none of the selling security holders nor any of their affiliates, officers, directors or principal equity holders has held any position or office or has had any material relationship with us within the past three years. None of the selling security holders listed above owned 1% or more of our outstanding common stock either before or after this offering.

Information concerning the selling security holders may change from time to time and any changed information will be set forth in additional supplements to the prospectus supplement if and when necessary. In addition, the


conversion rate and, therefore, the number of shares of common stock issuable upon conversion of the notes, is subject to adjustment under certain circumstances.
