&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For the three months ended May 31, 2013, the
Company issued 70,000 warrants in connection with the issuance of Convertible Promissory Notes referenced in Note 5 below. These
warrants were issued between March 1, 2013 and May 14, 2013, are exercisable at $3.00 per share and expire between March 1, 2017
and May 14, 2017. These warrants vest immediately. The Company analyzed the transaction for derivative liability and determined
it did not apply.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In connection with the issuance of the Convertible
Promissory Notes, we issued placement agent warrants in an aggregate amount to purchase 8,480 shares of common stock. These placement
agent warrants are exercisable at $2.50 per share, have a term of 5 years and a cashless exercise feature and vest immediately.
The fair value of these warrants was determined to be $25,498, as calculated using the Black-Scholes model. Assumptions used in
the Black-Scholes model included: (1) a discount rate of 0.75%; (2) an expected term of 5 years; (3) an expected volatility of
301%; and (4) zero expected dividends.&lt;/p&gt;
