What does it mean if I receive more than one proxy card?

Many of our stockholders hold their shares in more than one account
and may receive separate proxy cards or voting instructions forms for each of those accounts. If you receive more than one GOLDproxy
card, your shares are registered in more than one name or are registered in different accounts. Please sign, date and return or otherwise
submit your proxy with respect to each GOLDproxy card you receive to ensure that all of your shares are voted.

Additionally, please note that Deep Track has stated
its intention to nominate a slate of four candidates for election as directors at the Annual Meeting in opposition to the
Board Nominees. If Deep Track proceeds with its nominations, you may receive proxy solicitation materials from Deep
Track, including an opposition proxy statement and a white proxy card or white voting instruction form that may be sent to
you by or on behalf of Deep Track. The Board recommends that you disregard and do NOT return any white proxy card or white voting instruction form you receive from or on behalf of Deep Track.

Voting to “WITHHOLD” with respect to the Deep
Track Nominees on a white proxy card or white voting instruction form that may be sent to you by or on behalf of Deep Track
is NOT the same as voting for the Board Nominees because a vote to “WITHHOLD” with respect to the Deep Track
Nominees on its white proxy card or white voting instruction form will revoke any proxy you
