[1] In 2010, all unvested options related to the acquisition of HBE. HBE used the simplified method for calculating the expected life of the option, and the Company used this method for calculating the expected life of the options assumed. In 2011 and 2012, no unvested options were granted and the expected life was equal to the life of the option.

[2] The risk-free interest rate is based on U.S. Treasury yields in effect at the time of grant with a term equal to the expected term of the options.

[3] In 2010, 2011, and 2012, the Company estimated implied volatility based upon trailing volatility.

[4] Forfeitures are estimated at the time of grant based upon historical information. Forfeitures will be revised, if necessary, in subsequent periods if actual forfeitures differ from estimates. In 2010, the estimated forfeitures for the HBE options were based upon the historical information of HBE option holders.

[5] The Company has no history or expectation of paying dividends on its common stock.
