STOCK OPTIONS: 2000 STOCK OPTION PLAN Our 2000 Stock Option Plan provides for the grant of incentive stock options to our full-time employees (who may also be directors) and nonstatutory stock options to non-employee directors, consultants, customers, vendors or providers of significant services. The exercise price of any incentive stock option may not be less than the fair market value of the common stock on the date of grant or, in the case of an optionee who owns more than 10% of the total combined voting power of all classes of our outstanding stock, not be less than 110% of the fair market value on the date of grant. The exercise price, in the case of any nonstatutory stock option, must not be less than 75% of the fair market value of the common stock on the date of grant. The amount reserved under the 2000 Stock Option Plan is 10,000 options. At March 31, 2015, all of the grants previously made under the 2000 Stock Option Plan had expired and 200 restricted shares had been issued under the plan, with 9,800 available for future issuance. 2003 CONSULTANT STOCK PLAN Our 2003 Consultant Stock Plan, as amended from time to time (the "Stock Plan"), adopted by us in August 2003, advances our interests by helping us obtain and retain the services of persons providing consulting services upon whose judgment, initiative, efforts and/or services we are substantially dependent, by offering to or providing those persons with incentives or inducements affording such persons an opportunity to become owners of our common stock. Over several years, we issued 150,000 shares under the Stock Plan and discontinued using the Stock Plan in October 2012. 2010 STOCK INCENTIVE PLAN In August 2010, we adopted the 2010 Stock Incentive Plan, which provides incentives to attract, retain and motivate employees and directors whose present and potential contributions are important to our success by offering them an opportunity to participate in our future performance through awards of options, the right to purchase common stock, stock bonuses and stock appreciation rights and other awards. A total of 70,000 common shares were initially reserved for issuance under the 2010 Stock Incentive Plan. In August 2010, we filed a registration statement on Form S-8 for the purpose of registering 70,000 common shares issuable under this plan under the Securities Act, and in July 2012, we filed a registration statement on Form S-8 for the purpose of registering 100,000 common shares issuable under this plan under the Securities Act. At March 31, 2015, we had 28,845 shares available under this plan. 2012 DIRECTORS COMPENSATION PROGRAM In July 2012, our Board of Directors approved a board compensation program that modifies and supersedes the 2005 Directors Compensation Program, which was previously in effect. Under the 2012 program, in which only non-employee directors may participate, an eligible director will receive a grant of $35,000 worth of ten-year options to acquire shares of common stock, with such grant being valued at the exercise price based on the average of the closing bid prices of the common stock for the five trading days preceding the first day of the fiscal year. In addition, under this program, eligible directors will receive cash compensation equal to $500 for each committee meeting attended and $1,000 for each formal board meeting attended. In the fiscal year ended March 31, 2013, our Board of Directors granted ten-year options to acquire an aggregate of 33,342 shares of our common stock, all with an exercise price of $3.80 per share, to our four outside directors under the 2012 program. In the fiscal year ended March 31, 2014, our Board of Directors granted ten-year options to acquire an aggregate of 31,911 shares of our common stock, all with an exercise price of $4.10 per share, to our five outside directors under the 2012 program. In the fiscal year ended March 31, 2015, our Board of Directors granted ten-year options to acquire an aggregate of 11,053 shares of our common stock, all with an exercise price of $9.50 per share, to our three outside directors under the 2012 program. At March 31, 2015 we had issued 26,757 options under the old 2005 program to outside directors and 79,309 options to employee-directors, 21,756 outside directors’ options had been forfeited, 5,000 outside directors’ options had been exercised, 79,309 employee-directors’ options had been forfeited and no options under the old 2005 program remained outstanding. On June 6, 2014, our Board of Directors approved certain changes to the 2012 program. Under this modified program, a new eligible director will receive an initial grant of $50,000 worth of options to acquire shares of common stock, with such grant being valued at the exercise price based on the average of the closing bid prices of the common stock for the five trading days preceding the first day of the fiscal year. These options will have a term of ten years and will vest 1/3 upon grant and 1/3 upon each of the first two anniversaries of the date of grant. In addition, at the beginning of each fiscal year, each existing director eligible to participate in the modified 2012 program also will receive a grant of $35,000 worth of options valued at the exercise price based on the average of the closing bid prices of the common stock for the five trading days preceding the first day of the fiscal year. Such options will vest on the first anniversary of the date of grant. In lieu of per meeting fees, eligible directors will receive an annual board retainer fee of $30,000. The modified 2012 program also provides for the following annual retainer fees: Audit Committee Chair - $5,000, Compensation Committee chair - $5,000, Audit Committee member - $4,000, Compensation Committee member - $4,000 and lead independent director - $15,000. STAND-ALONE GRANTS From time to time our Board of Directors grants restricted stock or common share purchase options or warrants to selected directors, officers, employees and consultants as equity compensation to such persons on a stand-alone basis outside of any of our formal stock plans. The terms of these grants are individually negotiated. On June 8, 2009, our Board of Directors approved the grant to Mr. Joyce of 80,000 shares of restricted common stock at a price per share of $12.00, the vesting and issuance of which occurred in equal installments over a thirty-six-month period that commenced on June 30, 2010. As of March 31, 2015, we had issued 499,763 options (of which 146,810 have been exercised or cancelled) and authorized the issuance of 80,000 shares of restricted stock outside of the 2005 Directors Compensation Plan, the 2012 Directors Compensation Plan, the 2000 Stock Option Plan, the 2003 Consultant Stock Plan and the 2010 Incentive Stock Plan.

The following outlines the significant weighted average assumptions used to estimate the fair value with respect to stock options utilizing the Binomial Lattice option pricing model for the years ended March 31, 2015 and March 31, 2014:
| Year Ended March 31,
| 2015 |  | 2014
Risk free interest rate | 2.60% |  | 0.38% to 2.65%
Average expected life | 10 years |  | 3 to 10 years
Expected volatility | 90.23% |  | 91.05% to 102.67%
Expected dividends | None |  | None
The detail of the options outstanding and exercisable as of March 31, 2015 is as follows:
|  |  | Options Outstanding |  |  | Options Exercisable |
Range of Exercise Prices |  |  | Number Outstanding |  |  | Weighted Average Remaining Life (Years) |  |  | Weighted Average Exercise Price |  |  | Number Outstanding |  |  | Weighted Average Exercise Price |
$4.00 - $9.50 |  |  |  | 190,547 |  |  |  | 8.56 years |  |  | $ | 6.03 |  |  |  | 107,780 |  |  | $ | 5.56 |

We recorded stock-based compensation expense related to share issuances and to options granted totaling $416,481 and $607,946 for the fiscal years ended March 31, 2015 and 2014, respectively. These expenses were recorded as stock compensation included in payroll and related expenses in the accompanying consolidated statement of operations for the years ended March 31, 2015 and 2014. Our total stock-based compensation for fiscal years ended March 31, 2015 and 2014 included the following:
|  | March 31, 2015 |  |  | March 31, 2014 |
Vesting of restricted stock grant |  | $ | – |  |  | $ | 64,444 |
Incremental fair value of option modifications |  |  | – |  |  |  | 1,914 |

Total Stock-Based Compensation |  | $ | 416,481 |  |  | $ | 607,946 |
As of March 31, 2015, we had $341,982 of remaining unrecognized stock option expense, which is expected to be recognized over a weighted average remaining vesting period of 1.10 years. On March 31, 2015, our stock options had a negative intrinsic value since the closing price on that date of $9.50 per share was below the weighted average exercise price of our stock options.
