[b] Issued 2016 Private Placement On June 17, 2016, the Company closed the first tranche of a non-brokered private placement of 892,858 common shares at a price of U.S. $0.56 (the “Private Placement”) with a group of investment funds controlled by OrbiMed Advisors, LLC (“OrbiMed”), the Company’s majority shareholder.

[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. At the Annual General and Special Meeting held on June 13, 2016, the Company’s shareholders’ approved all unallocated options, rights and other entitlements under the 2008 Plan and the ability of the Company to continue granting options under the plan. Of the 2,183,453 stock options authorized for grant under the 2008 Plan as at June 30, 2016, options for 1,378,161 shares were outstanding and 805,292 stock options were available for future grant. The following assumptions were used to estimate the fair value of options granted during the six month period ended June 30, 2016, and 2015 using a Black-Scholes option-pricing model: Six Months Ended June 30, 201 6 201 5 Risk-free interest rates 1.04 % 1.31 % Expected dividend yield 0 % 0 % Expected life (in years) 5.7 5.8 Expected volatility 125 % 121 % Fair value per stock option $ 0.74 $ 0.67 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 six month period ended June 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 June 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 - 0.92 674,137 9.09 0.73 160,662 0.78 1.02 - 1.80 224,113 6.97 1.49 185,773 1.48 2.20 344,561 5.79 2.20 344,561 2.20 3.00 - 3.10 135,350 6.72 3.09 131,218 3.10 0.60 - 3.10 1,378,161 7.69 1.45 822,214 1.90 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, June 30, 2016 131,861 0.89 The restricted share units that were granted during the six month period ended June 30, 2016 were to settle a director compensation liability that was recorded in accounts payable and accrued liabilities. The $100,000 liability has been excluded from the change in accounts payable and accrued liabilities on the consolidated statement of cash flows. Of the 272,931 RSUs authorized for grant under the RSU Plan as at June 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 fair market value of the DSU’s is determined based upon the number of DSUs granted and the quoted price of the Company’s stock on the trading day immediately preceding the determination date. The duration of the vesting period and other vesting terms applicable to the grant of the DSU’s shall be determined by the Board. Number Weighted average of DSUs exercise price # $ Balance, December 31, 2015 - - DSUs granted 86,918 0.85 Balance, June 30 , 2016 86,918 0.85 The deferred share units that were granted during the six month period ended June 30, 2016 were to settle a director compensation liability that was recorded in accounts payable and accrued liabilities.

[g] Common share purchase warrants At June 30, 2016, there were 86,848,002 warrants outstanding to purchase shares of common stock, with expiry dates ranging from November 7, 2016 to December 15, 2024. Of the total 86,848,002 warrants outstanding, 86,103,744 warrants (the warrants related to the 2011 financing) entitle the holder thereof to purchase 1/20th of a common share of the Company at a price of $1.461 per whole common share; 636,557 warrants (the private placement warrants) entitle the holder thereof to purchase one common share of the Company at a price of $3.58 per common share; 52,796 warrants entitle the holder thereof to purchase one common share of the Company at a price of $1.831 per common share; and 54,905 warrants entitle the holder thereof to purchase one common share of the Company at a price of $1.00 per common share. There has been no common share purchase warrant transactions during the three months ended June 30, 2016. The estimated fair value of the warrants related to the 2011 financing is reassessed at each balance sheet date using the Black-Scholes option pricing model. The following assumptions were used to value the warrants on the following balance sheet dates: As at June 30, 2016 2015 Risk-free interest rates 0.52 % 0.49 % Expected dividend yield 0 % 0 % Expected life (in years) 0.5 1.5 Expected volatility 124 % 100 % Fair value of warrant $ 0.0112 $ 0.0156 [h] Earnings per common share 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. 86,848,002 warrants, 1,378,161 stock options, 131,861 restricted share units, and 86,918 deferred share units have been excluded from the computation of diluted earnings per share for the three and six month periods ended June 30, 2016 as the Company has incurred a net loss during the periods and their inclusion would be anti-dilutive to the loss per share (2015 – 86,865,691 warrants, 1,333,835 stock options and 112,489 restricted share units were excluded). |
