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.
