Why? Chill
We have been advised that our common stock is subject to a "chill." A chill is a restriction placed by Depository Trust Clearing ("DTC") on one more of DTC's services, such as limiting a DTC participant's ability to make a deposit or withdrawal of the security at DTC. A chill may remain imposed on a security for just a few days or for an extended period of time depending upon the reasons for the chill and whether the issuer or transfer agent corrects the problem. We do not know why a chill was placed upon our common stock. We are in the process of learning why and intend to. (Page 6)
