The following applies to Shareholders who wish to appoint a person (a “Third Party Proxyholder”) other than the management nominees set forth in the form of proxy or Voting Instruction Form as proxyholder, including Non- Registered Shareholders who wish to appoint themselves as proxyholder to attend, participate in or vote at the Meeting.

Shareholders who wish to appoint a Third Party Proxyholder to attend, participate in or vote at the Meeting as their proxy and vote their Common Shares MUST submit their proxy or Voting Instruction Form (as applicable) appointing such Third Party Proxyholder AND register the Third Party Proxyholder, as described below. Registering your proxyholder is an additional step to be completed AFTER you have submitted your proxy or Voting Instruction Form. Failure to register the proxyholder will result in the proxyholder not receiving a username to attend, participate in or vote at the Meeting.

•Step 1: Submit your proxy or Voting Instruction Form: To appoint a Third Party Proxyholder, insert such person’s name in the blank space provided in the form of proxy or Voting Instruction Form (if permitted) and follow the instructions for submitting such form of proxy or Voting Instruction Form. This must be completed prior to registering such proxyholder, which is an additional step to be completed once you have submitted your form of proxy or Voting

Instruction Form. If you are a Non-Registered Shareholder located in the United States, you must also provide Odyssey with a duly completed legal proxy if you wish to attend, participate in or vote at the Meeting or, if permitted, appoint a third party as your proxyholder.

•Step 2: Register your proxyholder: To register a proxyholder, Shareholders must send an email to appointee@odysseytrust.com by 1:00 p.m. (Eastern Time) on June 20, 2025 and provide Odyssey with their proxyholder’s contact information, amount of Common Shares appointed, name in which the Common Shares are registered if they are a registered Shareholder, or name of broker where the Common Shares are held if a Non- Registered Shareholder, so that Odyssey may provide the proxyholder with a username via email. Without a username, proxyholders will not be able to attend, participate in or vote at the Meeting.

If you are a Non-Registered Shareholder and wish to attend, participate in or vote at the Meeting, you have to insert your own name in the space provided on the Voting Instruction Form sent to you by your Intermediary, follow all of the applicable instructions provided by your Intermediary AND register yourself as your proxyholder, as described above. By doing so, you are instructing your Intermediary to appoint you as proxyholder. It is important that you comply with the signature and return instructions provided by your Intermediary.
