(a)

Expected volatility is based upon the Company’s historical volatility.

(b)

Since a sufficient period of historical volatility did not exist, the Company’s expected volatility was based on a combination of the Company’s available historical volatility and the historical volatility of a peer group of companies within similar industries and similar size as the Company.

(c)

Because the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term for these grants, the Company utilized the simplified method in developing an estimate of the expected term of these options.
