                                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.

We appreciate your time and careful consideration.
