Please note that under a rule amendment adopted by the New York Stock Exchange for shareholder meetings held on or after January 1, 2010, brokers are no longer allowed to vote securities held in their clients' accounts on uncontested elections of directors unless the client has provided voting instructions (it will continue to be the case that brokers cannot vote their clients' securities in contested director elections). Consequently, if you want us to vote your securities on your behalf on the election of directors, you must provide voting instructions to us. Voting on matters presented at shareholder meetings, particularly the election of directors is the primary method for shareholders to influence the direction taken by a publicly-traded company. We urge you to participate in the election by returning the enclosed voting instruction form to us with instructions as to how to vote your securities in this election.

In order for your broker to exercise this discretionary authority, proxy material would need to have been mailed at least 15 days prior to the meeting date, and one or more of the matters before the meeting must be deemed "routine" in nature according to NYSE guidelines. If these two requirements are met and you have not communicated to us prior to the first vote being issued, we may vote your securities at our discretion on any matters deemed to be routine. We will nevertheless follow your instructions, even if our discretionary vote has already been given, provided your instructions are received prior to the meeting date. The following instructions provide specifics regarding the meeting for which this voting form applies. Instruction 1 All proposals for this meeting are considered "routine". We will vote in our discretion on all proposals, if your instructions are not received. If your securities are held by a bank, your securities cannot be voted without your specific instructions.
