Company accounts for employee stock-based compensation in accordance with the guidance of FASB ASC Topic 718, <i>Compensation
– Stock Compensation </i>which requires all share-based payments to employees, including grants of employee stock options,
to be recognized in the financial statements based on their fair values.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><font style="font: 10pt Times New Roman, Times, Serif">The
Company has adopted a stock option and award plan to attract, retain and motivate its directors, officers, and employees. Options
provide the opportunity to acquire a proprietary interest in the Company and to benefit from its growth. Vesting terms and conditions
are determined by the Board of Directors at the time of the grant. The current Plan provides for the issuance of up to 2,823,199
common shares for directors, officers, and employees.</font></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 6pt"><font style="font: 10pt Times New Roman, Times, Serif">The
Company granted 1,305,000 new options in the May 31, 2013 period. The Company did not grant any stock options to employees in
fiscal 2013, but did grant 775,000 stock options, net of terminations or departures, to employees during fiscal 2012. The Company
has estimated the fair value of employee options issued in fiscal 2014 as of the grant dates at $109,039 using the Black-Scholes
option pricing model. Compensation expense is being recognized over the vesting periods of the options which range from immediate
vesting to vesting over two years. Previously recognized compensation expense is reversed if an employee terminates service prior
to exercise and expiration of the option.</font></p>

consultants and other non-employees. In accordance with ASC Topic 505-50, these stock options and warrants issued as compensation

market value of the option or warrant, whichever can be more clearly determined. The fair value of the equity instrument is charged
directly to compensation expense or prepaid expense and additional paid-in capital, and amortized over the period during which
services are rendered. All warrants issued were valued using the Black-Scholes pricing model.</font></p>
