required to be withheld.

     or Affiliate.

          d. Nothing in the Plan shall be deemed to limit, in any way, the right
     of the Company or any Subsidiary or Affiliate to terminate a  Participant's
     employment or service with the Company (or such Subsidiary or Affiliate) at
     any time.

          e. Any decision or action taken by the Board or the Committee  arising
     out  of  or  in   connection   with   the   construction,   administration,
     interpretation  and effect of the Plan shall be conclusive and binding upon
     all Participants and any person claiming under or through any Participant.

thereto,  unless it is advised by  counsel  of its  selection  that it may do so
without  violation of the  applicable  Federal and State laws  pertaining to the
issuance of  securities  and the Company  may require any stock  certificate  so
issued to bear a legend, may give its transfer agent  instructions  limiting the
transfer  thereof,  and may  take  such  other  steps,  as in its  judgment  are
reasonably required to prevent any such violation.
