Stock Options and Warrants
 
Costs attributable to the issuance of stock options and share purchase warrants are measured at fair value at the date of issuance and offset with a corresponding increase in ‘Additional Paid in Capital' at the time of issuance. The fair value cost is computed utilizing the Black-Scholes model and assuming volatility based on U.S. Treasury yield rates for a similar period. The cost of these warrants was
not
recognized in the financial statements because they were granted in connection with raising capital for the Company. When the options or warrants are exercised, the receipt of consideration will be reported as an increase in stockholders' equity.
 
Concurrently with certain securities purchase agreements entered into, warrants to purchase the Company's Common Stock were issued to the subscribers. Each warrant is exercisable for a period of
five
years from the date of the securities purchase agreement at an exercise price of
$1.95
per share (Note
3
). The fair value cost at the date of issuance of these warrants was
$614,805.

6,
a warrant for the purchase of up to
115,385
shares of Common Stock exercisable for a
one
-year period was issued at an exercise price of

per share and another warrant for the purchase of up to
360,000
shares of Common Stock exercisable for a

-year period was issued at an exercise price of
