this Plan shall not be deemed compensation for purposes of computing benefits or
contributions under any retirement plan of the Corporation or its Subsidiaries

substantially all of the assets of the Corporation for the securities of another
corporation, the acquisition by another corporation of 80% or more of the
Corporation's then outstanding shares of voting stock or the recapitalization,

or by a resolution adopted prior to the occurrence of such merger,
consolidation, exchange, acquisition, recapitalization, reclassification,
liquidation or dissolution, that, for a period of at least thirty (30) days
prior to such event, such Option (whether or not vested) shall be exercisable as
to all Shares subject thereto, notwithstanding anything to the contrary herein
(but subject to the provisions of Paragraph 7(b)) and that, upon the occurrence
of such event, such Option shall terminate and be of no further force or effect;
provided, however, that the Committee may also provide, in its absolute
discretion, that even if the Option shall remain exercisable after any such
event, from and after such event, any such Option shall be exercisable only for
the kind and amount of securities and/or other property, or the cash equivalent
thereof, receivable as a result of such event by the holder of a number of
shares of Common Stock for which such Option could have been exercised
immediately prior to such event.

Participant without the Participant's consent.

     The Board of Directors may amend, suspend or terminate the Plan except that
no such action, other than an action under Paragraph 8 or 9 hereof, may be taken
which would decrease the exercise price of outstanding Options, change the
requirements relating to the Committee or extend the term of the Plan.

11.  Withholding Taxes
     -----------------

     The Corporation shall have the right to deduct from any cash payment made
under the Plan any federal, state or local income or other taxes required by law
to be withheld with respect to such payment. It shall be a condition to the
obligation of the Corporation to deliver shares of Common Stock upon the
exercise of an Option that the Participant pay to the Corporation such amount as
may be requested by the Corporation for the purpose of satisfying any liability
for such withholding taxes. Any Option Agreement may provide that the
Participant may elect, in accordance with any conditions set forth in such
Option Agreement, to pay a portion or all of such withholding taxes in shares of
Common Stock.
