Because time is short, we are sending a copy of the Board's most recent proxy materials directly to you. You may use any of the WHITE proxy forms you have received from your broker or bank with Chad's proxy materials to vote for the Board's nominees. Please sign and return your WHITE proxy form so that it is received prior to the September 9 Annual Meeting. We urge you not to send in any gold proxy card you may receive from the dissident. If you have already sent a gold proxy card back, you may revoke your vote by signing and returning a later dated WHITE proxy form to support the Board's nominees. Since only your latest dated proxy counts, please make certain that your latest dated proxy is the Board's WHITE proxy form. Thank you for your support and for your prompt attention to this matter.
