STOCK BASED COMPENSATION

Incentive Stock Option Plan . The Company’s Incentive Stock Option Plan authorizes the issuance of shares of its Common Stock to persons that exercise options granted pursuant to the Plan. Only employees may be granted options pursuant to the Incentive Stock Option Plan. The option exercise price is determined by its directors but cannot be less than the market price of its common stock on the date the option is granted. The Company has reserved 1,000,000 common shares under this plan. No options have been issued under this plan as at February 28, 2015.

Non-Qualified Stock Option Plan . SDI’s Non-Qualified Stock Option Plan authorizes the issuance of shares of its Common Stock to persons that exercise options granted pursuant to the Plans. SDI’s employees, directors, officers, consultants and advisors are eligible to be granted options pursuant to the Plans, provided however that bona fide services must be rendered by such consultants or advisors and such services must not be in connection with the offer or sale of securities in a capital-raising transaction. By a resolution of the Board of Directors, the Company amended this plan to increase the number of common shares available under this plan from 2,250,000 to 4,500,000 effective October 10, 2007. The Company further amended its Non-Qualified Stock Option Plan to increase the number of Common Shares available under this plan to 5,000,000 and filed an S-8 registration statement on April 10, 2008.

Stock Bonus Plan . SDI’s Stock Bonus Plan allows for the issuance of shares of common stock to its employees, directors, officers, consultants and advisors. However bona fide services must be rendered by the consultants or advisors and such services must not be in connection with the offer or sale of securities in a capital-raising transaction. The Company has reserved 150,000 common shares under this plan. No options have been issued under this plan as at February 28, 2015.

Effective May 31, 2013, the Company adopted an incentive stock option plan (the “2013 Plan”), which replaces the stock option and stock bonus plans that were in place prior to adoption of the 2013 Plan. All outstanding options to purchase Common Shares granted by the Company under the prior plans are now governed by the 2013 Plan and the prior plans (an Incentive Stock Option Plan, a Non-Qualified Stock Option Plan, and a Stock Bonus Plan) have been terminated.
