                  used herein and not otherwise defined shall have the meanings

         (a)      Termination of Directorship. Upon termination of the Grantee's
                  membership on the Board of Directors of the Corporation for
                  any reason (other than death), the option granted hereby shall
                  terminate as of the date of termination of the Grantee's
                  membership on the Board, but in no event later than the date
                  of expiration of the option as provided above in this Section
                  2, provided that any unexpired portion of the option granted
                  hereby which is otherwise exercisable on the date of such
                  termination may be exercised by the Grantee at any time within
                  three (3) months following the date of such termination,
                  unless the Grantee dies during such three (3) month period,
                  but in no event later than the date of expiration of this
                  option as provided above in this Section 2. Such exercise
                  otherwise shall be subject to the terms and conditions of the
                  Plan and this Stock Option Agreement.

         (b)      Death. Upon death of the Grantee, the option granted hereby
                  shall terminate and be unexercisable on the date of death,
                  provided that any unexercised portion of the option granted
                  hereby which is otherwise exercisable at the date of death may
                  be exercised by his or her personal representatives, heirs, or
                  legatees ("Grantee's


<PAGE>

                  Successors") at any time prior to the expiration of one (1)
                  year after the Grantee's death, but in no event later than the
                  date of expiration of this option as provided above in this
                  Section 2. Such exercise otherwise shall be subject to the
                  terms and conditions of the Plan and this Stock Option
                  Agreement.

         3.       Exercise of Option. The terms, times and conditions of
                  exercise of the option granted hereby are as follows:

         The option shall be immediately exercisable, in whole or in part.

         The option price shall be payable in full upon the exercise of the
option in cash, by check, in shares of Common Stock, or in any combination
thereof.

         The option granted hereby shall be exercised by an irrevocable written
notice directed to the Secretary of the Corporation at the Corporation's
principal place of business.

         In addition, the terms contained in the Plan are incorporated into and
made a part of this Stock Option Agreement and this Stock Option Agreement shall
be governed by and construed in accordance with the Plan.

         4.       Nontransferability. The option granted hereby is not
                  assignable or transferable by the Grantee except by will, the
                  laws of descent and distribution, or pursuant to a qualified
                  domestic relations order as defined in Title I of the Employee
                  Retirement Income Security Act of 1974, as amended, and the
                  Internal Revenue Code of 1986, as amended. The option may be
                  exercised during the lifetime of the Grantee only by the
                  Grantee.

         5.       Limitation of Rights. Neither the Grantee nor the Grantee's
                  Successors shall have rights as a stockholder of the
                  Corporation with respect to shares of Common Stock covered by
                  this option until the Grantee or the Grantee's Successors
                  become the holder of record of such shares.

         6.       Common Stock Reserve. The Corporation shall at all times
                  during the term of this Stock Option Agreement reserve and
                  keep available such number of shares of Common Stock as will
                  be sufficient to satisfy the requirements of this Stock Option
                  Agreement.

         7.       Plan Controls. In the event of any actual or alleged conflict
                  between the provisions of the Plan and the provisions of this
                  Stock Option Agreement, the provisions of the Plan shall be
                  controlling and determinative.

         8.       Successors. This Stock Option Agreement shall be binding upon
                  any successor of the Corporation, in accordance with the terms
                  of this Stock Option Agreement and the Plan.
