[c] Stock option plan At the Annual General Meeting held September 3, 2008, the Company’s shareholders approved a stock option plan (“2008 Plan”). Under the plan, the Company may grant options to purchase common shares in the Company to employees, directors, officers and consultants of the Company. The exercise price of the options is determined by the Board to be equal to the fair market value of the commons shares on the grant date. The Company estimates the fair value of options on the date of the grant. The options vest over the requisite service period in accordance with terms as determined by the Board, typically over four years. Stock options expire no later than ten years from the date of grant. At the Annual General and Special Meeting held on June 18, 2013, the Company’s shareholders’ approved a change to the Company’s 2008 stock option plan permitting the maximum shares authorized to be issued under the plan to be up to 20% of the issued and outstanding common shares outstanding at any point in time.

Of the 2,183,453 stock options authorized for grant under the 2008 Plan as at September 30, 2016, options for 1,350,894 shares were outstanding and 832,559 stock options were available for future grant . The following assumptions were used to estimate the fair value of options granted during the nine month period ended September 30, 2016, and 2015 using a Black-Scholes option-pricing model: Nine Months Ended September 30, 2016 2015 Risk-free interest rates 1.04 % 2.04 % Expected dividend yield 0 % 0 % Expected life (in years) 5.71 5.88 Expected volatility 125 % 126 % Fair value per stock option $ 0.74 $ 1.33 The expected volatility reflects the assumption that the historical volatility of common stock of the Company over a period similar to the expected life of the options is indicative of future trends. The Company estimates the risk-free interest rate using the Bank of Canada bond yield with a remaining term equal to the expected life of the option. The Company uses the simplified method for estimating the stock option term for stock option grants during the nine month period ended September 30, 2016 as the Company has determined that the stock options are “plain vanilla” and historical share option exercises do not apply as the vesting term and contractual lives have significantly changed from those stock options exercised previously. At September 30, 2016, the following stock options were outstanding: Range of Number of shares under option Weighted average remaining contractual life Weighted average exercise price Number of options currently exercisable Weighted average exercise price $ # (years) $ # $ 0.60 - 0.92 658,155 8.83 0.73 172,249 0.78 1.02 - 1.80 217,948 6.70 1.49 188,652 1.48 2.20 340,401 5.53 2.20 340,401 2.20 3.00 - 3.10 134,390 6.47 3.10 131,077 3.10 0.60 - 3.10 1,350,894 7.42 1.45 832,379 1.88 The options expire at various dates from April 2, 2022 to March 23, 2026.

At the Annual General and Special Meeting held on June 13, 2016, the Company’s shareholders’ approved all unallocated entitlements under the RSU Plan and the ability of the Company to continue granting Restricted Share Units (“RSUs”) under the RSU Plan. Under the plan, the Company may grant RSUs to employees, directors, and eligible consultants which entitle each participant to either one common share of the Company on a time vested basis or a cash payout equal to the number of vested RSUs multiplied by the then current market value of the RSUs. The fair market value of the RSUs is determined based upon the number of RSUs granted and the quoted closing price of the Company’s stock on the trading day immediately preceding the date of determination. The duration of the vesting period and other vesting terms applicable to the grant of the RSUs shall be determined by the Board. Number Weighted average of RSUs exercise price # $ Balance, December 31, 2015 112,489 1.02 RSUs granted 118,527 0.85 RSUs converted to common shares (99,155 ) (0.98 ) Balance, September 30, 2016 131,861 0.89 The restricted share units that were granted during the nine month period ended September 30, 2016 were to settle a director compensation liability that was recorded in accounts payable and accrued liabilities.

Of the 272,931 RSUs authorized for grant under the RSU Plan as at September 30, 2016, 141,070 RSUs are available for grant. [e] Deferred share unit plan At the Annual General and Special Meeting held on June 18, 2013, the Company’s shareholders approved a new non-employee director deferred share unit plan (“DSU Plan”). At the Annual General and Special Meeting held on June 13, 2016, the Company’s shareholders’ approved all unallocated entitlements under the DSU Plan and the ability of the Company to continue granting Deferred Share Units (“DSUs”) under the DSU Plan.

The duration of the vesting period and other vesting terms applicable to the grant of the DSU’s shall be determined by the Board.

The following assumptions were used to value the warrants on the following balance sheet dates: As at September 30, 2016 2015 Risk-free interest rates 0.51 % 0.52 % Expected dividend yield 0 % 0 % Expected life (in years) 0.25 1.25 Expected volatility 19 % 121 % Fair value of warrant $ 0.000007 $ 0.005300 [h] Earnings per common share The following is a reconciliation of the weighted average number of common shares outstanding used in calculating basic and diluted earnings (loss) per share (in thousands, except share and per share data): Three Months Ended Nine Months Ended 2016 2015 2016 2015 $ $ $ $ Numerator: Net income (loss) availabe to common shareholders $ 170 $ 729 $ (2,400 ) $ (373 ) Denominator: Weighted average number of common shares outstanding - basic 10,917,269 9,925,256 10,303,598 9,863,609 Weighted average effect of dilutive securities: RSUs 131,861 112,489 - - DSUs 86,918 - - - Warrants 3,963 - Stock options 33,363 - - - Weighted average number of common shares outstanding - diluted 11,173,374 10,037,745 10,303,598 9,863,609 Basic net income per share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares that would have been outstanding during the period assuming the issuance of common shares for all potential dilutive common shares outstanding using the treasury stock method. Dilutive potential common shares outstanding include outstanding warrants, stock options, restricted share units, and deferred share units. 86,793,097 warrants and 871,339 stock options have been excluded from the computation of diluted earnings per share for the three month period ended September 30, 2016 as their inclusion would be anti-dilutive to the earnings per share. 86,848,002 warrants, 1,350,894 stock options, 131,861 RSUs and 86,918 DSUs have been excluded from the computation of diluted earnings per share for the nine month period ended September 30, 2016 as the Company has incurred a net loss during the period and their inclusion would be anti-dilutive to the loss per share (2015 – 86,865,691 warrants and 1,287,631 stock options have been excluded from the three month period ended September 30, 2015 and 86,865,691 warrants, 1,287,631 stock options, and 112,489 RSUs have been excluded from the nine month period ended September 30, 2015). |
