proxy card or GOLDvoting instruction form. You will need the
control number included on your GOLDproxy card or GOLDvoting instruction form. You need only vote in one way (e.g., if
you vote by internet, you need not return the proxy card). We strongly encourage you to vote in advance to ensure your vote will be represented
at the Annual Meeting.

Voting on the Internet or by Telephone. If you are a stockholder
of record, detailed instructions for internet/telephone voting are attached to your GOLDproxy card. Your internet/telephone vote
authorizes the proxy holders to vote your shares in the same manner as if you signed and returned your GOLDproxy card by mail.
If you vote by telephone or the internet, please have your GOLDproxy card and control number available. The sequence of numbers
appearing on your card is your control number, and your control number is necessary to verify your vote. Except as noted below, if you
are a stockholder of record and you vote on the internet, your vote must be received by 8:59 p.m. Pacific Time on June 10, 2025. If you hold
shares in street name, you may be able to vote on the internet or by telephone as permitted by your bank, broker or other nominee.

Voting by Mail. If you are a stockholder of record and received these
proxy materials by mail, you may vote by completing, signing and dating your GOLDproxy card and returning it in the prepaid envelope.
If you sign and return your GOLDproxy card, but do not direct how your shares should be voted on a proposal, the proxy holders
will vote your shares “FOR” the four Board Nominees, “FOR” Proposals 2, 3, and 4, and “AGAINST” Proposal
5, as applicable. If you sign and return your GOLDproxy card, the proxy holders will vote your shares according to their discretion
to adjourn the Annual Meeting, including for the purpose of soliciting votes in accordance with our Board’s recommendations, and
on any other proposals and other matters that may be brought before the Annual Meeting.
