,400
shares of common stock are reserved and

six
months, in options of the Optionee that are fully vested and exercisable or in any combination of the foregoing. The options expire on dates determined by the Board of Directors, but
not
later than
ten
years from the date of grant.

The Company determines the fair value of options on the date of grant using a Black-Scholes-Merton option pricing model that uses assumptions based on expected option life, expected stock volatility and the risk-free interest rate. The expected volatility
assumptions used by the Company are based on the historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options. The Company bases its expected life assumption on its historical experience and on the terms and conditions of the stock options it grants to employees. The risk-free rate is based on the U.S. Treasury yield curve for the periods within the contractual life of the options in effect at the time of the grant. The Company also makes assumptions regarding estimated forfeitures that will impact the total compensation expenses recognized under the Plans.
