4. to transact such further or other business as may properly be brought before the Meeting or any adjournments thereof.

Only Shareholders whose names have been entered in the register of Shareholders as of the close of business on the Record Date will be entitled to receive notice of and vote at the Meeting.

Each common share of the Company (each, a "Common Share") held by a Shareholder that is entitled to vote at the Meeting will entitle the holder thereof to one vote at the Meeting or in advance of the Meeting by submitting their proxy form before the deadline.

A Shareholder may virtually attend the Meeting or may be represented by proxy. Shareholders are encouraged to complete, date, sign and return, in the envelope provided for that purpose, the accompanying form of proxy (the "Proxy") for use at the Meeting or any adjournment thereof.

If you are a non-registered holder of Common Shares and have received these materials through your broker, custodian, nominee or other intermediary (an "Intermediary"), please complete and return the Proxy or voting instruction form provided to you by your Intermediary in accordance with the instructions provided therein.

The Proxy confers discretionary authority with respect to: (i) amendments or variations to the matters of business to be considered at the Meeting; and (ii) other matters that may properly come before the Meeting.
