TO OUR SHAREHOLDERS:

We are writing to confirm and again cordially invite you to attend a special meeting of our shareholders to be held at The Renaissance Houston Hotel, 6 Greenway Plaza East, Houston, Texas 77046 on October 9, 2012, at 3:00 p.m. local time.  Unfortunately a communication error occurred during the printing of our proxy cards which state that the special meeting is to be held October 2, 2012.  For the avoidance of doubt, we confirm that the special meeting date is October 9, 2012, and we hope that the error and this letter are in no way an inconvenience.

Further please note the following: 

  • The proxy card which incorrectly states that the special meeting date is October 2, 2012 is still acceptable for mailed delivery;
  • All mailed proxies must be received by the Company’s stock transfer agent on or before 12:00 p.m. (Denver local time) on October 7, 2012; and 
  • All online votes must be received by the Company’s transfer agent on or before 12:00 p.m. (Denver local time) on October 7, 2012.

All shareholders are cordially invited to attend the special meeting. Whether or not you expect to attend the special meeting in person, please submit a proxy as soon aspossible. Noting the above, to submit a proxy use the Internet as described on the proxy card, or complete, date and sign the proxy card and return it in the envelope that has been previously provided, which requires no additional postage if mailed in the United States. If you attend the meeting, and if you so choose, you may withdraw your proxy and vote in person. If your shares are held in “street name” by your broker or other nominee, only that holder can vote your shares. You should follow the directions provided by your broker regarding how to instruct your broker to vote your shares. 

We look forward to a successful special meeting and are anticipating strong shareholder turnout.

Peter Ntephe, Chief Executive Officer
