DESCRIPTION OF SHARE CAPITAL
The following descriptions are summaries of the material terms of our articles of amendment to the articles of the corporation, as amended,
and our general by-laws. We refer in this section to our articles of amendment to the articles of the corporation, as amended, as our articles, and we refer to our general
by-laws as our by-laws.
General
Our authorized share capital consists of an unlimited number of common shares and an unlimited number of preferred shares, issuable in series,
all of which preferred shares will be undesignated. As of February 26, 2025, 297,987,669 common shares were outstanding and held of record by 79 shareholders.
Common Shares
The holders of our common
shares are entitled to one vote for each share held on all matters submitted to a vote of the shareholders. Holders of our common shares are entitled to receive ratably any dividends declared by our board of directors out of funds legally available
for that purpose, subject to any preferential dividend rights of any outstanding preferred shares. Under the terms of our contribution agreements with Western Economic Diversification Canada we are restricted from paying any dividends until we have
repaid the contributions thereunder in full, and with respect to the Canadian Governments Strategic Innovation Fund grant funding arrangements, we are restricted from paying any dividends or other shareholder distributions that would prevent
us from satisfying our obligations under the arrangement. Our common shares have no preemptive rights, conversion rights or other subscription rights or redemption or sinking fund provisions.
In the event of our liquidation, dissolution or winding up, holders of our common shares will be entitled to share ratably in all assets
remaining after payment of all debts and other liabilities and any liquidation preference of any outstanding preferred shares.
Preferred Shares
Our board of directors has the authority, without further action by our shareholders, to issue an unlimited number of preferred shares
in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences,
sinking fund terms and the number of shares constituting, or the designation of, such series, any or all of which may be greater than the rights of common shares. The issuance of our preferred shares could adversely affect the voting power of
holders of common shares and the likelihood that such holders will receive dividend payments and payments upon our liquidation, dissolution or winding up. In addition, the issuance of preferred shares could have the effect of delaying, deferring or
preventing a change in control of our company or other corporate action. No preferred shares are currently outstanding, and we have no present plan to issue any preferred shares.
