STOCK-BASED COMPENSATION PLANS
(4)         STOCK-BASED COMPENSATION PLANS

The Company's shareholders approved the 2005 Equity Incentive Plan ("2005 Plan") in June 2005.  An amendment to the 2005 Plan was approved at the June 2009 annual meeting of shareholders to increase the number of authorized shares of Common Stock issuable under the 2005 Plan from 425,000 shares to 625,000 shares.  An additional amendment to the 2005 Plan was approved at the June 2012 annual meeting of shareholders to increase the number of authorized shares of Common Stock issuable under the 2005 Plan by 150,000 shares from 625,000 shares to 775,000 shares.  The 2005 Plan provides for the grant of incentive stock options, restricted stock, restricted stock units and stock grants to employees (including officers and employee-directors) and non-statutory stock options to employees, directors and consultants. The objectives of the 2005 Plan are to attract and retain the best personnel and provide for additional performance incentives by providing employees with the opportunity to acquire equity in the Company.  As of March 31, 2013, there were 100,868 shares available for issuance under the 2005 Plan.  The 2005 Plan is administered by a committee of two or more independent directors from the Company's Board of Directors (the "Committee"). The Committee determines the eligible individuals to whom awards under the 2005 Plan may be granted, as well as the time or times at which awards will be granted, the number of shares subject to awards to be granted to any eligible individual, the life of any award, and any other terms and conditions of the awards in addition to those contained in the 2005 Plan. As of March 31, 2013, there were 248,002 vested options and 210,331 unvested options under the 2005 Plan.

The Company uses the Black-Scholes option-pricing model to estimate the fair value of each option granted with the following weighted average assumptions:

(1) The expected life, in years, of stock options is estimated based on historical experience.
(2) The risk-free interest rate is based on U.S. Treasury bills whose term is consistent with the expected life of the stock options.
(3) The expected volatility is estimated based on historical and current stock price data for the Company.
(4) Forfeitures are estimated based on historical experience.
