Shareholder Rights Plan	Note 10 — Shareholder Rights Plan The Company’s Board has the authority to issue up to 4,991,000 shares of Preferred Stock and to determine the price, rights (including conversion rights), preferences and privileges of those shares without any further vote or action by the shareholders. Consistent with this authority, in January, 2009 our Board adopted a Shareholder Rights Plan (as amended the “Rights Plan”) in which one purchase right was distributed as a dividend on each share of Common Stock held of record as of the close of business on February 10, 2009 (the “Rights”). The Rights Plan will expire in January, 2019. If exercisable, each Right will entitle its holder to purchase from the Company one one-thousandth of a share of a newly created Series B Preferred Stock of the Company for $20.00 (the “Purchase Price”). The Rights will become exercisable if any person or group becomes the beneficial owner of 15% or more of the Company’s Common Stock or has commenced a tender or exchange offer which, if consummated, would result in any person or group becoming the beneficial owner of 15% or more of the Company’s Common Stock. If any person or group becomes the beneficial owner of 15% or more of the Company’s Common Stock, each right will entitle its holder, other than the acquiring person, to purchase a number of shares of the Company’s or the acquirer’s Common Stock having a value of twice the Purchase Price. The Rights are deemed attached to the certificates representing outstanding shares of Common Stock.
