     Example: You  marked  your  proxy  in a way  that  made it hard  for us to
              understand.

     Restated Articles







o    If he asks why he should vote, indicate that:

     o    Horizon  Bancorp  would  like  to  have as  many  shares  as  possible

               card and indicate the return fax number at Horizon Bancorp.

                                          Proposal 4: Amended and Restated Articles                          Notice &
                                          o        Horizon's  current  articles  have never been amended       p. 25
                                                   to reflect current Indiana corporate law
                                          o        In   1986,   the   Indiana    corporation   law   was
                                                   substantially   revised  and   modernized,   and  the
                                                   current  articles  have not been  updated  to reflect
                                                   many of those changes
                                          o        The Amended and Restated
                                                   Articles also include other
                                                   changes, such as making the
                                                   language in some sections
                                                   easier to understand
                                          o        At least 70% of the total
                                                   outstanding shares must be
                                                   voted in favor of the
                                                   Restated Articles. That is
                                                   why it is necessary for each
                                                   shareholder to vote. A
                                                   failure to vote is
                                                   essentially a vote against.

                                          Proposal 3: Authorization of Preferred Shares                    Notice & pp.
                                          o        The  preferred   shares  will  provide  Horizon  with       23-24
                                                   another means for raising  capital if it is needed to

                                          o        Horizon has proposed the
                                                   authorization of the
                                                   Preferred Shares to provide
                                                   it with increased financial
                                                   flexibility by providing for
                                                   additional ways to raise
                                                   capital.
                                          o        The  Board  of   Directors  is  not   proposing   the
                                                    preferred shares for anti-takeover purposes

                                          o        A nationally known compensation consultant,  Frederic       p. 16
                                                   W. Cook & Co., recommended
                                                   that Horizon adopt an omnibus
                                                   stock plan to help attract
                                                   and retain key employees.
                                          o        The Board of Directors
                                                   believes that the Omnibus
                                                   Plan is a necessary tool for
                                                   Horizon to attract and retain
                                                   the best employees and to
                                                   more closely align their
                                                   interests with the interests
                                                   of shareholders
                                          o        The Board of Directors
                                                   believes that it is in the
                                                   best interest of Horizon to
                                                   adopt a plan as recommended
                                                   by Cook.

How many votes are required to approve    The  number  of  votes  required  differs   depending  on  the       p. 2
the proposals?                            proposal:

                                          Proposal 1: Election of Directors                                    p. 2
                                          A director  must  receive a plurality  of the votes cast (that
                                          means that a director  will be  elected  if he  receives  more
                                          votes  than any  opposing  candidate  for the open seat on the
                                          Board) [since only 4 directors  have been  nominated for the 4
                                          open seats,  each  director will be elected if he receives any
                                          "FOR" votes (regardless of the number of  "Withhold" votes)]

                                          Proposal 2: Adoption of Omnibus Plan                              pp. 2 & 16
                                          More  votes  must be voted in  favor of  adoption  of the plan
                                          than against adoption of the plan

                                          Proposal 3:  Authorization of Preferred Shares                    pp. 2 & 23
                                          More votes must be voted in favor of
                                          authorization of the preferred shares
                                          than against authorization of the
                                          preferred shares

                                          Proposal 4: Amended and Restated Articles                          pp. 2 &24
                                          At least 70% of the  outstanding  Common  Shares must be voted
                                          in favor of approval of the Amended and Restated Articles

Why does the number of votes required     The  Indiana   corporation   statute  and  Horizon's   current       p. 26
differ?                                   articles  specify  different vote  requirements  for different
                                          types of matters
