***IMPORTANT MESSAGE ABOUT VOTING YOUR SHARES***
Recently, NYSE and SEC rule changes were enacted changing how shares held in brokerage accounts are voted in director elections. If YOU do not vote your shares on proposal one (Election of Directors), your brokerage firm can no longer vote them for you; your shares will remain unvoted. Previously, if your broker did not receive instructions from you, they were permitted to vote your shares for you in director elections. However, starting January 1, 2010, under changes to NYSE Rule 452, brokers will no longer be allowed to vote uninstructed shares.
Therefore, it is very important that you vote your shares for all proposals including the election of directors.
In addition to checking the appropriate boxes on the enclosed vote instruction form, signing and returning it in the enclosed postage paid envelope, there are two additional convenient ways to vote that are available 24 hours a day:
