General Proxy Information

Solicitation of Proxies

The solicitation of proxies will be primarily by mail, but proxies may be solicited personally or by telephone by directors, officers, and employees of the Company. The Company will bear all costs of this solicitation. We have arranged to send a Notice of Internet Availability of Proxy Materials directly to Registered Shareholders, as well as Non-Registered Shareholders who have consented to their ownership information being disclosed by the Intermediary holding the Common Shares on their behalf(non-objecting beneficial owners). We have not arranged for Intermediaries to forward the Notice of Internet Availability of Proxy Materials to Non-Registered Shareholders who have objected to their ownership information being disclosed by the Intermediary holding the Common Shares on their behalf (objecting beneficial owners) under National Instrument 54-101 Communication with Beneficial Owners of Securities of a Reporting Issuer. As a result, objecting beneficial owners will not receive the Notice of Internet Availability of Proxy Materials and associated materials related to the Meeting unless their Intermediary assumes the costs of delivery.

Appointment and Revocation of Proxies

The individuals named in the accompanying form of proxy (the “Proxy”) are officers or directors of the Company, or solicitors for the Company. If you are a Registered Shareholder, you have the right to attend the Meeting or vote by proxy and to appoint a person or company other than the person designated in the Proxy, who need not be a Shareholder, to attend and act for you and on your behalf at the Meeting. You may do so either by inserting the name of that other person in the blank space provided in the Proxy or by completing and delivering another suitable form of Proxy.

If you are a Registered Shareholder, you may wish to vote by proxy even if you are able to attend the Meeting. Registered Shareholders electing to submit a proxy may do so by completing, dating and signing the Proxy and submitting it in accordance with the instructions on the Proxy.

In all cases, you should ensure that the Proxy is received at least 48 hours (excluding Saturdays, Sundays and holidays) before the Meeting or the adjournment thereof at which the Proxy is to be used.

Every Proxy may be revoked by an instrument in writing:

or in any other manner provided by law.

Only Registered Shareholders have the right to revoke a Proxy. Non-Registered Shareholders who wish to change their vote must, at least seven days before the Meeting, arrange for their respective Intermediaries to revoke the Proxy on their behalf. If you are a Non-Registered Shareholder, see “Voting by Non-Registered Shareholders” below for further information on how to vote your Common Shares.

Exercise of Discretion by Proxyholder

If you vote by proxy, the persons named in the Proxy (the “Proxyholder”) will vote or withhold from voting the Common Shares represented thereby in accordance with your instructions. If you specify a choice with respect to any matter to be acted upon, your Common Shares will be voted accordingly. The Proxy confers discretionary authority on the persons named therein with respect to:

In respect of a matter for which a choice is not specified in the Proxy, the persons named in the Proxy will vote the Common Shares represented by the Proxy “FOR” the approval of such matter. Management is not currently aware of any other matters that could come before the Meeting.

Voting by Non-Registered Shareholders

The following information is of significant importance to Shareholders who do not hold Common Shares in their own name. Non-Registered Shareholders should note that the only Proxies that can be recognized and acted upon at the Meeting are those deposited by Registered Shareholders.

If Common Shares are listed in an account statement provided to a Shareholder by an Intermediary, then in almost all cases, those Common Shares will not be registered in the Shareholder’s name on the records of the Company. Such Common Shares will more likely be registered under the name of the Shareholder’s Intermediary or an agent of that Intermediary. In the United States, the vast majority of such Common Shares are registered under the name of Cede & Co. (the registration name for the Depository Trust Company, which acts as nominee for many U.S. brokerage firms), and in Canada, under the name of CDS & Co. (the registration name for the Canadian Depository for Securities Limited, which acts as nominee for many Canadian brokerage firms).

If you have consented to disclosure of your ownership information, you will receive a request for voting instructions from the Company through BetaNXT, Inc. (“BetaNXT”). If you have declined to disclose your ownership information, you may receive a request for voting instructions from your Intermediary if they have assumed the cost of delivering the proxy statement and associated materials related to the Meeting. Every Intermediary has its own mailing procedures and provides its own return instructions to clients. However, most Intermediaries now delegate responsibility for obtaining voting instructions from clients to Broadridge Financial Solutions, Inc. (“Broadridge”) in the United States and in Canada.

If you are a Non-Registered Shareholder, you should carefully follow the instructions on the VIF received from BetaNXT or Broadridge in order to ensure that your Common Shares are voted at the Meeting. The VIF supplied to you will be similar to the Proxy provided to the Registered Shareholders by the Company. However, its purpose is limited to instructing the Intermediary on how to vote on your behalf.

The VIF sent by BetaNXT or Broadridge will name the same persons as the Company’s proxy to represent you at the Meeting. Although as a Non-Registered Shareholder you may not be recognized directly at the Meeting for the purposes of voting Common Shares registered in the name of your Intermediary, you, or a person designated by you (who need not be a Shareholder), may attend the Meeting as Proxyholder for your Intermediary and vote your Common Shares in that capacity. To exercise this right to attend the Meeting or appoint a Proxyholder of your own choosing, you should insert your own name or the name of the desired representative in the blank space provided in the VIF. Alternatively, you may provide other written instructions requesting that you or your desired representative attend the Meeting as Proxyholder for your Intermediary. The completed VIF or other written instructions must then be returned in accordance with the instructions on the form.

If you receive a VIF from BetaNXT or Broadridge, you cannot use it to vote Common Shares directly at the Meeting—the VIF must be completed as described above and returned in accordance with its instructions in advance of the Meeting in order to have the Common Shares voted.

Exercise of Discretion by Broker

For any shares you hold beneficially through U.S. brokerage accounts, if you do not return voting instructions to your U.S. broker on a timely basis, your U.S. broker will have the authority to vote your brokerage shares only on the proposal regarding the appointment and renumeration of our auditor. Your U.S. broker is prohibited from voting your shares on your behalf without your specific voting directions on the proposals for the election of directors, regarding the compensation of our named executive officers, and on any other proposal that may come before the Meeting. These “brokernon-votes” and abstentions will not be considered votes cast with respect to any of the proposals brought before the Meeting. Without specific directions, Canadian brokers are prohibited from voting their customers’ shares. If you do not provide voting directions, Canadian brokers are prohibited from voting your Common Shares on your behalf for all proposals.

Record Date and Quorum

The board of directors (the “Board”) of the Company has fixed the record date for the Meeting as the close of business on April 16, 2026 (the “Record Date”). Shareholders of record as of the Record Date are entitled to receive notice of the Meeting and to vote their Common Shares at the Meeting, except to the extent that any such Shareholder transfers any Common Shares after the Record Date and the transferee of those Common Shares establishes that the transferee owns the Common Shares and demands, not less than ten (10) days before the Meeting, that the transferee’s name be included in the list of Shareholders entitled to vote at the Meeting, in which case, only such transferee shall be entitled to vote such Common Shares at the Meeting.

Under the Company’s Articles, the quorum for the transaction of business at a meeting of Shareholders is at least one Shareholder present in person or by proxy at the meeting who holds, or who is otherwise permitted to vote shares of the Company at a meeting of Shareholders representing, in the aggregate at least thirty three andone-third percent (33 1/3%) of the issued shares entitled to be voted at the meeting.

Only Shareholders of record at the close of business on the Record Date will be entitled to vote in person or by Proxy at the Meeting or any adjournment or postponement thereof. To the knowledge of the directors and executive officers of the Company, as of the Record Date, no Shareholders beneficially own, or exercise control or direction over, directly or indirectly, Common Shares carrying 10% or more of the votes attached to the issued and outstanding Common Shares.
