Stock Repurchase Program

During each of the three-month periods ended March 31, 2013 and 2012, we did not repurchase any of our common stock under the terms of our Board-approved $1,000,000 stock repurchase program ("stock repurchase program"). As of March 31, 2013, approximately $782,600 remained available for future purchases under this program. We are not obligated to repurchase any specific number of shares and the stock repurchase program may be suspended or terminated at our discretion.
