         no event after the expiration of the term of the Option:

         a.       If a Non-Employee Director ceases being a director of the
                  Company for any reason other than the reasons identified in
                  subparagraph b. of this Section 9, the Non-Employee Director
                  shall have the right to exercise the Options as follows,
                  subject to the condition that no Option shall be exercisable
                  after the expiration of the term of the Option:

                  (1)      If the Non-Employee Director was a member of the
                           Board of Directors of the Company for five (5) or
                           more years, all outstanding Options become
                           immediately exercisable upon the date the
                           Non-Employee Director ceases being a director. The
                           Non-Employee Director may exercise the Options for a
                           period of thirty-six (36) months from the date the
                           Non-Employee Director ceased being a director,
                           provided that if the Non-Employee Director dies
                           before the thirty-six (36) month period has expired,
                           the Options may be exercised by the Non-Employee
                           Director's legal representative or any person who
                           acquires the right to exercise an Option by reason of
                           the Non-Employee Director's death for a period of
                           twelve (12) months from the date of the Non-Employee
                           Director's death.

                  (2)      If the Non-Employee Director was a member of the
                           Board of Directors of the Company for less than five
                           (5) years, the Non-Employee Director may exercise the
                           Options, to the extent they were exercisable at the
                           date the Non-Employee Director ceases being a member
                           of the Board, for a period of thirty (30) days
                           following the date the Non-Employee Director ceased
                           being a director, provided that, if the Non-Employee
                           Director dies before the thirty (30) day period has
                           expired, the Options may be exercised by the
                           Non-Employee Director's legal representative, or any
                           person who acquires the right to exercise an Option
                           by 

                                      -4-
   5

                           reason of the Non-Employee Director's death, for a
                           period of twelve (12) months from the date of the
                           Non-Employee Director's death.

                  (3)      If the Non-Employee Director dies while a member of
                           the Board, the Options, to the extent exercisable by
                           the Non-Employee Director at the date of death, may
                           be exercised by the Non-Employee Director's legal
                           representative, or any person who acquires the right
                           to exercise an Option by reason of the Non-Employee
                           Director's death, for a period of twelve(12) months
                           from the date of the Non-Employee Director's death.

                  (4)      In the event any Option is exercised by the
                           executors, administrators, legatees, or distributees
                           of the estate of a deceased optionee, the Company
                           shall be under no obligation to issue stock
                           thereunder unless and until the Company is satisfied
                           that the person or persons exercising the Option are
                           the duly appointed legal representatives of the
                           deceased optionee's estate or the proper legatees or
                           distributees thereof.

         b.       If a Non-Employee Director ceases being a director of the
                  Company due to an act of

                  (1)      fraud or intentional misrepresentation or

                  (2)      embezzlement, misappropriation or conversion of
                           assets or opportunities of the Company or any
                           Affiliate of the Company or

                  (3)      any other gross or willful misconduct as determined
                           by the Board, in its sole and conclusive discretion,

                  all Options granted to such Non-Employee Director shall
                  immediately be forfeited as of the date of the misconduct.

                  the date the Plan is approved by the shareholders of the
                  Company (the "Effective Date").

         b.       Any amendment to the Plan shall become effective when adopted
                  by the Board, unless specified otherwise, but no Option
                  granted under any increase in shares authorized to be issued
                  under this Plan shall be exercisable until the increase is
                  approved in the manner prescribed in Section 12 of this Plan.

12.      AMENDMENT OF THE PLAN

         a.       The Board of Directors may amend, suspend or terminate the
                  Plan at any time, but without shareholder approval, no
                  amendment shall materially increase the maximum number of
                  shares which may be issued under the Plan (other than
                  adjustments pursuant to Section 10 hereof), materially
                  increase the benefits accruing to Participants under the Plan,
                  materially modify the requirements as to eligibility for
                  participation or extend the term of the Plan. Approval of the
                  shareholders may be obtained, at a meeting of shareholders
                  duly called and held, by the affirmative vote of a majority of
                  the holders of the Company's voting stock who are present or
                  represented by proxy and are entitled to vote on the Plan.

         b.       It is intended that the Plan meet the requirements of Rule
                  16b-3 or any successor thereto promulgated by the Securities
                  and Exchange Commission under the Securities Exchange Act of
                  1934, as amended, including any applicable requirements
                  regarding shareholder approval. Amendments to the Plan shall
                  be subject to approval by the shareholders of the Company to
                  the extent determined by the Board of Directors to be
                  necessary to satisfy such requirements as in effect from time
                  to time.

         c.       Rights and obligations under any Option granted before any
                  amendment of this Plan shall not be materially and adversely
                  affected by amendment of the Plan, except with the consent of
                  the person who holds the Option, which consent may be obtained
                  in any manner that the Board or its delegate deems
                  appropriate.

         d.       The Board of Directors may not amend the provisions of
                  Sections 4, 6, 7, 8 and 9 hereof more than once every six (6)
                  months, other than to comport with changes in the Code, ERISA,
                  or the rules thereunder.

13.      TERMINATION OF THE PLAN

         a.       The Plan, unless sooner terminated, shall terminate at the end
                  of ten (10) years from the date the Plan is approved by the
                  shareholders of the Company. No Option may be granted under
                  the Plan while the Plan is suspended or after it is
                  terminated.

         b.       Rights or obligations under any Option granted while the Plan
                  is in effect, including the maximum duration and vesting
                  provisions, shall not be altered or impaired by suspension or
                  termination of the Plan, except with the consent of the person
                  who holds the Option, 

                                      -6-

   7

                  which consent may be obtained in any manner that the Board or
                  its delegate deems appropriate.

14.      REGISTRATION, LISTING, QUALIFICATION, APPROVAL OF STOCK AND OPTIONS

         If the Board shall determine, in its discretion, that it is necessary
         or desirable that the shares of common stock subject to any Option

         a.       be registered, listed or qualified on any securities exchange
                  or under any applicable law, or

         b.       be approved by any governmental regulatory body, or

         c.       approved by the shareholders of the Company, as a condition
                  of, or in connection with, the granting of such Option, or the
                  issuance or purchase of shares upon exercise of the Option,

         then the Option may not be exercised in whole or in part unless such
         registration, listing, qualification or approval has been obtained free
         of any condition not acceptable to the Board of Directors.

15.      NO RIGHT TO OPTION OR AS SHAREHOLDER

         a.       No Non-Employee Director or other person shall have any claim
                  or right to be granted an Option under the Plan, except as
                  expressly provided herein. Neither the Plan nor any action
                  taken hereunder shall be construed as giving any Non-Employee
                  Director any right to be retained in the service of the
                  Company.

         b.       Neither a Non-Employee Director, the Non-Employee Director's
                  legal representative, nor any person who acquires the right to
                  exercise an Option by reason of the Non-Employee Director's
                  death shall be, or have any of the rights or privileges of, a
                  shareholder of the Company in respect of any shares of common
                  stock receivable upon the exercise of any Option granted under
                  this Plan, in whole or in part, unless and until certificates
                  for such shares shall have been issued.

16.      GOVERNING LAW

         The validity, construction, interpretation, administration and effect
         of this Plan and any rules, regulations and actions relating to this
         Plan will be governed by and construed exclusively in accordance with
         the laws of the State of Delaware.
