except that approval of the shareholders of the Company shall be required for
any amendment for which such approval is necessary to comply with Rule 16b-3
under the Exchange Act or any other applicable law, regulation, or listing
requirement, or to qualify for an exemption or characterization that is deemed
desirable by the Committee. No amendment of the Plan shall materially and
adversely affect any right of any Non-Employee Director with respect to any
shares of Common Stock theretofore issued without such Non-Employee Director's
written consent.

9.       Termination.

         The Plan shall terminate upon the earlier of the following dates or
events to occur: (a) upon the adoption of a resolution of the Board terminating

any Non-Employee Director with respect to any shares of Common Stock theretofore
issued without such Non-Employee Director's written consent.

10.      Miscellaneous Provisions.

         (a) 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.

Committee may require a Non-Employee Director to pay to the Company such sum as
may be necessary to discharge any obligation of the Company with respect to
taxes, assessments or other governmental charges imposed on property or income
received by such Non-Employee Director pursuant to the Plan. In accordance with
rules and procedures established by the Committee and in the discretion of the
Committee, such payment may be in the form of cash or property, or may be
effected by delivery of a lesser number of shares.

         (d)    The expenses of the Plan shall be borne by the Company.

         (e) The Plan shall be unfunded. The Company shall not be required to
establish any special or separate fund or to make any other segregation of
assets to assure the issuance of shares hereunder.

         (f) The Company shall not be required to issue fractions of shares.
Whenever under the terms of the Plan a fractional share would be required to be
issued, the Non-Employee Director shall be paid in cash for such fractional
share based upon the same Fair Market Value which was used to determine the
number of shares to be issued on the relevant payment date.
