With the ongoing impact of the COVID-19 pandemic, the Company has decided to conduct the Meeting virtually via live audio webcast to ensure the health and safety of shareholders, employees and the communities in which we live. The Board of Directors and management of the Company believe that enabling shareholders to attend the Meeting virtually will also lead to greater shareholder attendance and participation. Shareholders will be able to listen to the Meeting, all in real time, via live webcast available online using the TSX meeting platform at https://virtual-meetings.tsxtrust.com/1378 (Meeting ID#1378; Password: nighthawk2022). Registered shareholders and duly appointed proxy holders who participate in the Meeting virtually will also be able to ask questions and vote. Shareholders will be able to access the Meeting using an internet connected device such as a laptop, computer, tablet or mobile phone, and the Meeting platform will be supported across browsers and devices that are running the most updated version of the applicable software plugins (except for Internet Explorer). It is important to note that shareholders accessing the Meeting virtually must remain connected to the internet at all times during the Meeting in order to vote when balloting commences. It is your responsibility to ensure internet connectivity for the duration of the Meeting.
