Dear Shareholder:

     We recently  mailed you proxy  materials  in  connection  with our upcoming
Annual Meeting of Shareholders to be held on Friday, May 8, 2003.

     According  to our latest  records,  we have not  received  your proxy card.
Regardless  of the  number  of shares  you own,  it is  important  that they are
represented and voted for at our annual meeting.

     Proposal  number  four on the proxy  card,  "the  adoption  of Amended  and
Restated Articles of Incorporation", requires approval by the holders of seventy
percent (70%) of the outstanding common shares. Therefore to avoid costly delays
or an  adjournment of our annual  meeting,  it is very important that you return
your proxy card.

     The Board of Directors  unanimously  recommends that the shareholders  vote
"FOR" all proposals on the proxy card.

     Please take a moment to VOTE your  shares by SIGNING,  DATING & MAILING the
enclosed proxy card in the return envelope provided.

     Thank you for your continued support.



                                  Best Regards,

                                  /s/ Craig M. Dwight
