Registered Shareholders

There are two methods by which registered shareholders (“Registered Shareholders”), whose names are shown on the books or records of the Company as owning common shares no par value of the Company (“Common Shares”), can vote their Common Shares at the Meeting either in person at the Meeting or by proxy. Should a Registered Shareholder wish to vote in person at the Meeting, the Registered Shareholder should attend the Meeting where his or her vote will be taken and counted. Although we are making a toll-free number available to listen to the Meeting, if you wish to vote the day of the Meeting, you must do so in person. Should the Registered Shareholder not wish to attend the meeting or not wish to vote in person, his or her vote may be cast by proxy through one of the methods described below and the Common Shares represented by the proxy will be voted or withheld from voting, in accordance with the instructions as indicated in the form of proxy, on any ballot that may be called for, and if a choice was specified with respect to any matter to be acted upon, the shares will be voted accordingly.

A Registered Shareholder may vote by proxy by using one of the following methods: (i) by paper form of proxy to be returned by mail or delivery; (ii) by Internet; or (iii) by telephone. The methods of using each of these procedures are as follows:

Voting by Mail. A Registered Shareholder may vote by mail or delivery by completing, dating and signing the form of proxy and depositing it with Computershare Investor Services Inc. (the “Transfer Agent”) using the envelope provided or by mailing it to Computershare Investor Services Inc., Attention: Proxy Department, 100 University Avenue, 8th Floor, Toronto, Ontario M5J 2Y1 or to the Corporate Secretary of the Company at 10758 West Centennial Road, Suite 200, Littleton, Colorado 80127for receipt no later than 11:59 p.m. (ET) on Monday, June 2, 2025, or if the Meeting is adjourned, by no later than 1:00 p.m. Mountain Time on the last business day preceding the reconvened Meeting.

Voting by Internet. A Registered Shareholder may vote by Internet by accessing the following website: www.envisionreports.com/URGQ2025, and going to “vote now.” When you log on to the site you will be required to input a control number as instructed on the form of proxy. Please see additional information on the form of proxy. Registered Shareholders may vote by Internetfor receipt no later than 11:59 p.m. (ET) on Monday, June 2, 2025, or if the Meeting is adjourned, no later than 1:00 p.m. Mountain Time on the last business day preceding the reconvened Meeting.

Voting by Telephone. A Registered Shareholder may vote by telephone by calling the toll-free number 1-866-732-8683 from a touch tone phone. When you telephone you will be required to input a control number as instructed on the form of proxy. Please see additional information on the form of proxy. Registered Shareholders may vote by telephonefor receipt no later than 11:59 p.m. (ET) on Monday, June 2, 2025, or if the Meeting is adjourned, no later than 1:00 p.m. Mountain Time on the last business day preceding the reconvened Meeting.

Voting by mail or the Internet are the only methods by which a Registered Shareholder may choose an appointee other than the management appointees named on the proxy and must be completed by the Registered Shareholder or by an attorney authorized in writing or, if the Registered Shareholder is a corporation or other legal entity, by an authorized officer or attorney.

Non-Registered Shareholders (Beneficial Owners)

If you hold shares through a broker, bank or other nominee, you will receive material from that firm asking how you want to vote and instructing you of the procedures to follow in order for you to vote your shares. If the nominee does not receive voting instructions from you, it may vote only on proposals that are considered “routine” matters under applicable rules. Each of the proposals at the Meeting, other than Proposal No. 2, are “non-routine” matters and therefore an intermediary holding shares for a beneficial owner will not have the authority to vote on those matters in the absence of instructions from the beneficial owner. A nominee’s inability to vote on some proposals because it lacks discretionary authority to do so is commonly referred to as a “broker non-vote.” Broker non-votes are not counted in the tabulation of votes cast on a particular proposal and therefore will not have an effect on the approval of that proposal.

Notice and Access

We distribute our proxy materials to shareholders via the Internet under the “Notice and Access” approach permitted by rules of the SEC. This approach conserves natural resources and reduces our distribution costs, while providing a timely and convenient method of accessing the materials and voting. On or before April 25, 2025, we mailed a Notice of Internet Availability of Proxy Materials to participating shareholders, containing instructions on how to access the proxy materials on the Internet to vote your shares over the Internet or by telephone. You will not receive a printed copy of the proxy materials unless you request them. If you would like to receive a printed copy of our proxy materials, including a printed proxy card on which you may submit your vote by mail, then you should follow the instructions for obtaining a printed copy of our proxy materials contained in the Notice of Internet Availability of Proxy Materials.
