STOCK BASED COMPENSATION
NOTE 5. STOCK BASED COMPENSATION

The stock based compensation cost that has been charged against income by the Company was $85,172 and $61,680 for the six months ended June 30, 2012 and 2011, respectively, for options previously awarded by the Company.

In June 2011, we extended our consulting agreement for investor relations services.  The agreement was made effective as of April 15, 2011 and remained in effect until April 14, 2012 at which time it was renewed on a month to month basis.  We agreed to compensate the consultant with a monthly fee and reimbursement of expenses incurred in connection with and pursuant to the agreement.  The agreement may be terminated by either party at any time upon 30 days written notice.  In addition the Company granted the consultant warrants to purchase 25,000 shares of our common stock, with cashless exercise rights, at an exercise price of $1.75 per share. On May 10, 2011, the date of grant, 6,250 shares vested immediately and the remainder vest at 33 1/3% per year.  The fair value of these warrants on the date of grant was $11,201.
