(2)	The dividend rate that will be paid out on the underlying shares during the expected term of the options. The Company does not currently pay dividends on its common stock, as such, the dividend rate is assumed to be zero percent.

(4)	The period of time for which the option is expected to be outstanding. The Company analyzed historical exercise behavior to estimate the life.
