[GRAPHIC OMITTED] January 18, 2002 IMPORTANT NOTICE Dear Shareholder: Last fall, we sent you voting material relating to your Fund's shareholder meeting. The meeting was initially held on October 19, 2001 and was adjourned to February 19, 2002 to allow us to obtain additional votes. Thank you for the timely return of your proxy card. Our records reflect that you abstained on Proposal #2. This proposal authorizes the Trustees to adopt an amended and restated Declaration of Trust and requires the affirmative vote of 67% of the outstanding shares of your Fund. Over 60% of the Fund's shares have voted in favor of this proposal, but we need your vote to reach the 67% requirement. The issue is of utmost importance to your Fund. We are contacting you again to urge you to reconsider your previous vote. The proposed Declaration of Trust would give the Fund's Trustees more flexibility to react more quickly to changes in competitive and regulatory conditions, and, as a result, will allow the Funds to operate more efficiently. Adoption of the restated Declaration of Trust would not alter in any way the Trustees' fiduciary obligations to act with due care and in the shareholders' best interest. Your vote is important and your participation in the affairs of your Fund does make a difference. If you decide to change your vote, you can do so o By phone - call toll-free 1-888-832-5695. Representatives are available Monday through Friday from 9 a.m. to 11 p.m. and Saturday from noon to 6 p.m. Eastern time. o By Internet - go to www.proxyvote.com anytime, and enter the control number on your proxy card. o By touch-tone phone - call 1-800-690-6903 anytime. Be sure to have your proxy card available when you call. o By mail - complete the proxy card and return it in the enclosed return envelope. Receipt of a vote with a later date will revoke your previous vote on this proposal. If you do not wish to change your vote, no action is required. The Board of Trustees has carefully reviewed and approved this proposal. If you have any questions or would like an additional proxy statement, please call 1-888-832-5695 Monday through Friday from 9 a.m. to 11 p.m. and Saturday from noon to 6 p.m. Eastern time.
