NOTICE-AND-ACCESS

Notice is also hereby given that the Company has decided to use the notice-and-access method of delivery of materials for the Meeting. The notice-and-access method allows for the Company to deliver Meeting materials via the internet in accordance with the applicable rules set forth in National Instrument 54-101 Communications with Beneficial Owners of Securities of a Reporting Issuer. Under the notice-and-access system, Shareholders still receive a proxy or voting instruction form (as applicable) enabling them to vote at the Meeting. However, instead of a paper copy of the Information Circular, the audited financial statements of the Company as at and for the fiscal year ended December 31, 2025 and related management's discussion and analysis of financial condition, Shareholders receive notification with information on how they may access such Meeting materials electronically. The use of this alternative method of delivery is more environmentally friendly as it will help reduce paper use and will also reduce the cost of printing and mailing
