Dear Shareholder:

     I would  like to begin  by  apologizing  for the  attention  you have  been
receiving  regarding  the  funds'  shareholder  meetings.  By now,  you may have
received  numerous  follow-up  mailings  and phone  calls from the funds'  proxy
agent, Georgeson Shareholder  Communications  Corporation.  The reason for these
proactive  measures  is to  ensure  that  the  funds  meet the  two-thirds  vote
requirement  necessary for the adoption of an amended  restated  Declaration  of
Trust.  The funds have committed  countless  hours and resources to this effort,
which will prove  worthless if the two-thirds  vote needed to pass this proposal
is not obtained. The adjourned meeting at which this proposal will be considered
is scheduled for Wednesday, December 5, 2001.

     We  strongly  urge you to vote on this  matter.  You may think that this is
irrelevant  to you,  but I  assure  you  that  this  proposal  will  give us the
flexibility to provide you and all other  shareholders  with the modernized form
of investment  vehicle you have come to expect.  We would be happy to answer any
questions regarding this proposal. Please contact us at 1-888-832-5695.

     To date,  approximately 1.2 million shareholders in the funds have voted on
this proposal representing 2.3 billion shares, of which 92% have voted in favor.
We need your vote to wrap this up!
