Why did you send me this Proxy Statement and GREEN proxy card?
We sent you this Proxy Statement and the enclosed GREEN proxy card because you own shares of common stock of the Company. Your proxy is being solicited by the Board of Directors of the Company. This Proxy Statement provides you with information that will help you cast your vote at the Special Meeting. However, you do not need to attend the Special Meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed GREEN proxy card or submit your proxy by telephone or the Internet according to the instructions on the GREEN proxy card.
