Stock Option Program Description

For the year ended December 31, 2013 the Company had two equity compensation plans, the 1996 Stock Option Plan (the “1996 Plan”) and the 2006 equity compensation plan (the “2006 Plan”). The 1996 Plan has expired for the purposes of issuing new grants. However, the 1996 Plan will continue to govern awards previously granted under that plan. The 2006 Plan has been approved by the Company’s Shareholders. Equity compensation grants are designed to reward employees and executives for their long term contributions to the Company and to provide incentives for them to remain with the Company. The number and frequency of equity compensation grants are based on competitive practices, operating results of the Company, and government regulations.

The maximum number of shares issuable over the term of the 1996 Plan was limited to 65 million shares (without giving effect to subsequent stock splits). Options granted under the 1996 Plan typically have an exercise price of 100% of the fair market value of the underlying stock on the grant date and expire no later than ten years from the grant date. On August 27, 2013, the Board of Directors of Enova Systems, Inc. approved amendments to the Company’s 2006 Equity Compensation Plan to (a) increase the number of shares authorized for issuance thereunder from 3,000,000 shares to 9,000,000 shares and (b) to increase the number of shares of common stock that may be issued to an individual in any calendar year from 500,000 shares to 5,000,000 shares. The 2006 Plan has a total of 4,400,000 and 270,000 shares that were granted in 2013 and 2012, respectively.

Stock-based compensation expense related to stock options was $16,000 and $171,000 for the years ended December 31, 2013 and 2012, respectively. As of December 31, 2013, the total compensation cost related to non-vested awards not yet recognized is $42,000. The remaining period over which the future compensation cost is expected to be recognized is 26 months.

Stock-based compensation expense recognized in the Statement of Operations for the years ended December 31, 2013 and 2012 has been based on awards ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. If the actual number of forfeitures differs from that estimated by management, additional adjustments to compensation expense may be required in future periods.

The following is a summary of changes to outstanding stock options during the fiscal year ended December 31, 2013 and 2012:

Valuation and Expense Information

The fair value of stock-based awards to officers and employees is calculated using the Black-Scholes option pricing model. The Black-Scholes model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of options granted is calculated by using the SAB 107 “simplified method” of estimating the expected term which is derived by taking the average of the time to vesting and the full term of the option. The risk-free rate selected to value any particular grant is based on the bond equivalent yields that corresponds to the pricing term of the grant effective as of the date of the grant. The expected volatility is based on the historical volatility of the Company’s stock price. These factors could change in the future, affecting the determination of stock-based compensation expense in future periods.

The fair values of all stock options granted during the fiscal years ended December 31, 2013 and 2012 were estimated on the date of grant using the following range of assumptions:

	Years Ended December 31,
	2013			2012
Expected life (in years)		1.5			1.5- 6.5
Average risk-free interest rate		1.66	%		1.66	%
Expected volatility		118	%		108% - 136	%
Expected dividend yield		0	%		0	%
Forfeiture rate		3	%		3	%

The estimated fair value of grants of stock options to nonemployees of the Company is charged to expense, if applicable, in the financial statements. These options vest in the same manner as the employee options granted under each of the option plans as described above.
