5.        STOCKHOLDERS’ EQUITY

The number of common shares reserved for issuance under the OrthoLogic 1987 option plan was 4,160,000 shares. This plan expired during October 1997. In May 1997, our stockholders adopted a new stock option plan (the “1997 Plan”). The 1997 Plan reserved for issuance 1,040,000 shares of Common Stock. Subsequent to its original adoption, the Board of Directors and stockholders approved amendments to the 1997 Plan that increased the number of shares of common stock reserved for issuance to 4,190,000. The 1997 Plan expired in March 2007. In May 2006, our stockholders approved the 2005 Equity Incentive Plan (the “2005 Plan”) and reserved 2,000,000 shares of our common stock for issuance. In May 2009, our stockholders approved the reservation of an additional 1,250,000 shares of common stock for issuance under the 2005 Plan, which increased the total shares available for grant under the 2005 Plan to 3,250,000 shares. At December 31, 2013, 48,519 shares remained available to grant under the 2005 Plan (the 1997 plan and the 2005 plan are collectively referred to as “The Plans”). Two types of options may be granted under the Plans: options intended to qualify as incentive stock options under Section 422 of the Internal Revenue Code (the “Code”) and other options not specifically authorized or qualified for favorable income tax treatment by the Code. All eligible employees may receive more than one type of option. Any director or consultant who is not an employee of the Company shall be eligible to receive only nonqualified stock options under the Plans.

The Plans provide that in the event of a takeover or merger of the Company in which 100% of the equity of the Company is purchased or a sale of all or substantially all of the Company’s assets, 75% of all unvested employee options will vest immediately and the remaining 25% will vest over the following twelve month period. If an employee or holder of stock options is terminated as a result of or subsequent to the acquisition, 100% of that individual’s stock option will vest immediately upon employment termination.

We used the Black-Scholes model with the following assumptions to determine the total fair value of $34,000 and $59,000 for options to purchase 255,000 and 595,000 shares of our common stock issued during 2013 and 2012, respectively.

On January 17, 2011, the Board of Directors of the Company granted John M. Holliman 50,000 shares of restricted common stock (fair value on the date of grant of $19,000), which vested January 17, 2012. On January 17, 2012, the Board of Directors was each granted 10,000 shares of unrestricted common stock (total fair value on the date of grant of $18,000). The Company had no unvested common stock share awards as of December 31, 2013 and no common stock awards were made in 2013.

It is the Company’s policy to issue options from stockholder approved incentive plans. However, if the options are issued as an inducement for an individual to join the Company, the Company may issue stock options outside of stockholder approved plans. The options granted to employees under stockholder approved incentive plans have a ten-year term and normally vest over a two to four-year period of service. All stock options are granted with an exercise price equal to the current market value on the date of grant and, accordingly, stock options have no intrinsic value on the date of grant. Based on the closing market price of the Company’s common stock at December 31, 2013 of $0.26, stock options exercisable or expected to vest at December 31, 2013, have intrinsic value of $6,000.

Warrants
