The Company’s Board of Directors has authorized 32,000,000 total shares of capital stock, of which 30,000,000 are designated as common stock and 2,000,000 are designated as preferred stock.  The Board of Directors has the authority to establish one or more classes of preferred stock and to determine, within any class of preferred stock, the preferences, rights and other terms of such class.

As of December 31, 2012, the Company has reserved 3,907,686 shares of common stock for issuance: 3,070,803 shares upon exercise of outstanding stock options; and 836,883 shares for future grants under the Company’s 1995 Long-Term Incentive Plan.

On March 21, 2011, the Board of Directors authorized the purchase of up to $3.0 million of the Company’s common stock in accordance with the safe harbor provisions of Rule 10b-18 of the Securities Exchange Act of 1934.  During the year ended December 31, 2011, the Company repurchased 824,374 shares at an aggregate cost of $1.6 million.  During the year ended December 31, 2012, the Company repurchased 280,113 shares at an aggregate cost of $531,000.

Preferred Stock Rights

On March 21, 2011, the Board of Directors of the Company declared a dividend, payable to holders of record as of the close of business on April 1, 2011, of one preferred stock purchase right (a “Right”) for each outstanding share of common stock, par value $0.01 per share, of the Company (the “Common Stock”).  In addition, the Company will issue one Right with each new share of Common Stock issued.  In connection therewith, on March 21, 2011, the Company entered into a Stockholder Protection Rights Agreement (as amended from time to time, the Rights Agreement) with Continental Stock Transfer & Trust Company, as Rights Agent, which has a term of three years, unless amended by the Board of Directors in accordance with the terms of the Rights Agreement.  Upon approval of both an independent committee of the Board of Directors and the Board of Directors, the Rights Plan can be extended for up to three years.  The Rights will initially trade with and be inseparable from the Common Stock and will not be evidenced by separate certificates unless they become exercisable.  Each Right entitles its holder to purchase from the Company one-hundredth of a share of participating preferred stock having economic and voting terms similar to the Common Stock at an exercise price of $8.00 per Right, subject to adjustment in accordance with the terms of the Rights Agreement, once the Rights become exercisable.  Under the Rights Agreement, the Rights become exercisable if any person or group acquires 20% or more of the Common Stock or, in the case of any person or group that owned 20% or more of the Common Stock as of March 21, 2011, upon the acquisition of any additional shares by such person or group.  The Company, its subsidiaries, employee benefit plans of the Company or any of its subsidiaries and any entity holding Common Stock for or pursuant to the terms of any such plan are accepted.  Upon exercise of the Right in accordance with the Rights Agreement, the holder would be able to purchase a number of shares of Common Stock from the Company having an aggregate market price (as defined in the Rights Agreement) equal to twice the then-current exercise price for an amount in cash equal to the then-current exercise price.  In addition, the Company may, in certain circumstances and pursuant to the terms of the Rights Agreement, exchange the Rights for one share of Common Stock or an equivalent security for each Right or, alternatively, redeem the Rights for $0.001 per Right.  The Rights will not prevent a takeover of our Company, but may cause substantial dilution to a person that acquires 20% or more of the Company’s Common Stock.
