None of the selling securityholders has, or within the past three years has had, any position, office or other material relationship with us or any of our predecessors or affiliates. None of the selling securityholders, other than BNP Arbitrage SNC which owns 4,100 shares, and Mainstay Convertible Fund which owns 3,700 shares, owns any shares of common stock. Our registration of the TECONS, the junior subordinated debentures and the common stock issuable upon conversion of the TECONS does not necessarily mean that the selling shareholders will sell all or any of these securities. Because the selling securityholders may offer all or some portion of the TECONS, the junior subordinated debentures or the common stock issuable upon conversion of the TECONS, we cannot estimate the amount of the TECONS, the junior subordinated debentures or the common stock issuable upon conversion of the TECONS that will be held by the selling securityholders upon termination of any such sales. In addition, the selling securityholders identified above may have sold, transferred or otherwise disposed of all or a portion of their TECONS, since the date on which they provided the information regarding their TECONS, in transactions exempt from the registration requirements of the Securities Act. See "Plan of Distribution." Only selling securityholders identified above who beneficially own the offered securities set forth opposite each such selling securityholder's name in the preceding table may sell such offered securities pursuant to the registration statement. Prior to any use of this prospectus in connection with an offering of the TECONS and/or the junior subordinated debentures or common stock issuable upon conversion of the TECONS by any securityholder not identified above, we will supplement this prospectus to include the name and number of shares beneficially owned by the selling securityholder intending to sell such TECONS and/or common stock, and the number of TECONS and/or shares of common stock to be offered. If necessary, we will disclose in a prospectus supplement any other required information about any of the selling securityholders.
