Stockholders' Equity

NOTE J – STOCKHOLDERS’ EQUITY

Common Stock

In 2013, we issued 3,552,357 shares of common stock, valued at $9,279,887, representing payment for principal and interest on our Initial Note and Additional Note as described in NOTE I

During the three-month period ended March 31, 2013, we issued 2,010,500 shares of common stock to accredited investors upon exercise of their outstanding warrants.

Warrants

We have 2,087,500 warrants outstanding. 1,562,500 warrants are attached to our Senior Convertible debt discussed further in NOTES I and M. The conversion price on these warrants is $3.60 and are set to expire on November 9, 2016. The remaining 525,000 warrants remain were attached to our former Series G Preferred stock. These warrents have a conversion price of $2.44 and expired on April 13, 2014. See NOTE M for further information on these warrants.

Stock-Based Compensation

We have one active stock incentive plan, the 2005 Stock Incentive Plan. The 1997 Stock Incentive Plan expired on August 17, 2007. As of that date, options could no longer be granted from that Plan but any granted and unexercised options continued to exist until exercised or they expired. As of December 31, 2013 all outstanding options in the 1997 Stock Incentive Plan have expired. The 2005 Stock Incentive Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units and stock appreciation rights. We initially reserved 2,500,000 of our authorized but unissued shares of common stock for issuance under the Plan, and, at the time the Plan was adopted, not more than 500,000 of these shares could be used for restricted stock awards and restricted stock units. On January 16, 2008, the Board of Directors approved amendments to the Plan to add 2,500,000 shares of common stock to the Plan, to allow any number of shares to be used for restricted stock awards, to clarify certain other provisions in the Plan and to submit the amended Plan for stockholder approval. The amended Plan was approved at the annual meeting of stockholders on May 7, 2008. On June 3, 2010, our stockholders’ approved an amendment to the 2005 Stock Incentive Plan which resulted in the addition of 3,000,000 shares of common stock to the Plan. Any incentive option and non-qualified option granted under the Plan must provide for an exercise price of not less than the fair market value of the underlying shares on the date of grant, but the exercise price of any incentive option granted to an officer, director or eligible employee owning more than 10% of our outstanding common stock must not be less than 110% of fair market value on the date of the grant.

Share-based compensation expense recognized during the period is based on the value of the portion of share-based payment awards that is ultimately expected to vest. As share-based compensation expense recognized in the statement of operations is based on awards ultimately expected to vest, it can be reduced for estimated forfeitures. The ASC topic Stock Compensation requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The share based compensation charged against income for the three-month periods ended March 31, 2014 and 2013 was $492,775 and $688,580.

The weighted average estimated fair value of stock options granted during the three-month periods ended March 31, 2014 and 2013 was $1.28 and $1.44, respectively. The weighted average fair value of stock options granted is determined using the Black-Scholes option-pricing model, which values options based on the stock price at the grant date, the expected life of the option, the estimated volatility of the stock, the expected dividend payments, and the risk-free interest rate over the life of the option. The Black-Scholes option valuation model was developed for estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Because option valuation models require the use of subjective assumptions, changes in or variations from these assumptions can materially affect the fair value of the options. The assumptions used in the Black-Scholes model were as follows for stock options granted during the three-month periods ended:
