Rule 17 of the AIM Rules requires, inter alia, that an AIM quoted company must notify the market of any changes of which it is aware to its Shareholders’ interests in three percent or more of the Common Shares and changes thereto (of any movements through a percentage point upwards or downwards). As the Company is incorporated in Alberta, provisions have been incorporated into the Articles (and approved by Shareholders at the Special Meeting held on 4 June 2018) which, to the extent possible, mirror the requirements of DTR 5 which require that Shareholders holding interests in three percent or more of the Company’s Common Shares inform the Company thereof and to inform the Company of relevant subsequent changes thereto.

In accordance with the Company’s Articles of Association, all shareholders in the Company holding an interest in three per cent. or more of the Company’s shares (including all legal and beneficial interests, direct or indirect, or interests in financial instruments which are referenced to such shares, of such shareholders) are required to notify the Company of their interest and of any subsequent relevant changes to their holdings. Those changes shall include any increase or decrease to such holdings through any single percentage threshold.

Shareholders are therefore requested to notify the Company in accordance with Rule 17 of the AIM Rules.

The Company has 537,740,991 Common Shares of no par value in issue. There are no share restrictions.
