         the Optionee's status as an employee, consultant or advisor.

                  (b)   The members of the Board shall not be liable for any
         act, omission or determination taken or made in good faith with

         any directors' and officers' liability or similar insurance coverage
         that may from time to time be in effect.

                  (c)   Any issuance or transfer of Shares to the Optionee, or

         expenses and costs arising out of any actions taken by the Company to
         enforce its rights under this Option.

                  (f)   Records of the Company shall be conclusive for all
         purposes under this Option, unless determined by the Board to be
         incorrect.

                  (g)   Any action required of the Company relating to this
         Option shall be by resolution of the Board or by a person authorized
         to act by resolution of the Board.

                  (h)   If any provision of this Option is held to be illegal
         or invalid for any reason, the illegality or invalidity shall not
         affect the remaining provisions of this Option, but such provision
         shall be fully severable, and this Option shall be construed and
         enforced as if the illegal or invalid provision had never been
         included in this Option.

                  (i)   Any person entitled to notice under this Option may
         waive such notice.
