Dear Shareholder:

To date we have not received your vote on a very important proposal being voted on by your Fund. As one of the largest un-voted shareholders, your vote is particularly critical to the Fund being able to conduct business at the adjourned Special Meeting of Shareholders, scheduled for February 6, 2007.

Please take a moment now to cast your vote so that your shares are represented.

After careful review and consideration, your Board of Trustees approved the proposal, as set forth in the proxy materials, and they believe that the proposal is in the best interest of each Fund’s shareholders. Accordingly they recommend that you also vote in favor of the proposal.

YOUR VOTE IS CRITICAL, because we need over 50% of all of your Fund’s shareholders to vote to either approve or reject the proposal. If you don’t vote there may not be enough votes to reach any conclusion on the proposal.

A new ballot is enclosed with this letter for your convenience. Please vote your proxy using one of the convenient methods that are outlined on your ballot or simply mark your vote on the enclosed ballot, sign and return it to us in the postage-paid envelope provided.

Should you have any questions regarding this information, please call 1-800-283-2519.

Thank you for your cooperation.

John T. Hailer, President
