[1] The fair market value of the asset was determined by using the Company's closing stock price as reflected in the over-the-counter market.

[2] The term is the contractual remaining term, allocated among twelve equal intervals for purposes of calculating other inputs, such as volatility and risk-free rate.

[3] The implied expected life, and equivalent volatility and risk-free interest rate amounts are derived from the binomial.

[4] The Company does not have a market trading history upon which to base its forward-looking volatility. Accordingly, the Company selected peer companies that provided a reasonable basis upon which to calculate volatility for each of the intervals described in (2), above.

[5] The risk-free rates used for inputs represent the yields on zero coupon U.S. Government Securities with periods to maturity consistent with the intervals described in (2), above.
