Stockholders’ Equity

Preferred Stock Purchase Rights

On September 16, 2003, the Company’s Board of Directors adopted a shareholder rights plan and declared a dividend of one preferred share purchase right (a “Right”) for each share of common stock of the Company outstanding on October 6, 2003 and with respect to each share of common stock issued thereafter. The rights become exercisable only after any person or group (the “Acquiring Person”) becomes or would become the beneficial owner of 15% or more of the Company’s outstanding common stock.

Each Right entitles the registered holder to purchase from the Company 1/100 of a Series A Junior Participating Preferred Share at a price of $100.00 per 1/100 of a Preferred Share, subject to adjustment. In the event that any person or group becomes an Acquiring Person, each holder of a Right, other than Rights that are or were beneficially owned by the Acquiring Person (which will thereafter be void), will thereafter have the right to receive, upon exercise thereof at the then current exercise price of the Right, that number of Common Shares having a market value of two times the exercise price of the Right, subject to certain possible adjustments. If the Company is acquired in certain mergers or other business combination transactions, or 50% or more of the assets or earning power of the Company and its subsidiaries (taken as a whole) are sold, each holder of a Right (other than Rights that have become void under the terms of the Rights Agreement) will thereafter have the right to receive, upon exercise of the Right at the then current exercise price of the Right, the number of common shares of the acquiring company (or, in certain cases, one of its affiliates) having a market value of two times the exercise price of the Right. At any time prior to the time that a person or group has become an Acquiring Person, the Company’s Board of Directors may redeem the Rights in whole, but not in part, at a price of $.001 per Right, subject to adjustment, payable in cash. The Rights will expire at the close of business on September 16, 2013, unless extended or earlier redeemed by the Company. No preferred shares have been issued or are outstanding under the shareholder rights plan as of December 31, 2012.
