            (b)   a termination of employment by the Participant within two (2)
                  years after a Change in Control for one or more of the
                  following reasons:

               (1)   the assignment to such Participant of any duties
                     inconsistent in a way adverse to such Participant, with
                     such Participant's positions, duties, responsibilities and
                     status with the Company immediately prior to the Change in
                     Control, or a reduction in the duties and responsibilities
                     held by the Participant immediately prior to the Change in
                     Control; a change in the Participant's reporting
                     responsibilities, title or offices as in effect immediately
                     prior to the Change in Control that is adverse to the
                     Participant; or any removal of the Participant from or any
                     failure to re-elect the Participant to any position with
                     the Company that such Participant held immediately prior to
                     the Change in Control except in connection with such
                     Participant's: (i) assignment to a new position at a higher
                     annual base salary and guideline bonus; or (ii) termination
                     of employment by the Company for Just Cause; or

               (2)   With respect to any Participant who is a member of the
                     Board of Directors immediately prior to the Change in
                     Control, any failure of the shareholders of the Company to
                     elect or reelect, or of the Company to appoint or
                     reappoint, the Participant as a member of the Board of
                     Directors;

               (3)   A reduction by the Company in the Participant's base annual
                     salary or guideline (target) bonus as in effect immediately
                     prior to the Change in Control; the failure by the Company
                     to continue in effect, or the taking of any action by the
                     Company that would adversely affect such Participant's
                     participation in or materially reduce such Participant's
                     benefits under, any employee benefit plan or compensation
                     plan in which such Participant was participating
                     immediately prior to the Change in Control; provided,
                     however, that in the aggregate such actions by the Company
                     significantly reduce the Participant's total compensation
                     (i.e., the sum of Participant's annual base salary,
                     guideline (target) bonus, and the aggregate value to the
                     Participant of all employee benefit or compensation plans);
                     or the failure by the Company, without the Participant's
                     consent, to pay to the Participant any portion of the
                     Participant's current compensation, or to pay to the
                     Participant any portion of an installment of deferred
                     compensation under any deferred compensation program of the
                     Company; or

               (4)   The Company requires the Participant to be based anywhere
                     other than the Participant's present work location or a
                     location within thirty-five (35) miles from the present
                     location; or the Company requires the Participant to travel
                     on Company business to an extent substantially more
                     burdensome than such Participant's travel obligations
                     during the period of twelve (12) consecutive months
                     immediately preceding the Change in Control;

 
                                       5

               provided, however, that in the case of any such termination of
               employment by the Participant under this subparagraph (b), such
               termination shall not be deemed to be a Qualifying Termination
               unless the termination occurs within 120 days after the
               occurrence of the event or events constituting the reason for the
               termination; or

            (c)   a termination of employment by the Company other than a
                  termination for Just Cause, or a termination of employment by
                  the Participant for one of the reasons set forth in (b) above,
                  following a Potential Change in Control, if the Participant
                  can demonstrate that such termination or circumstance in (b)
                  above leading to termination (i) was at the request of a third
                  party with which the Company had entered into negotiations or
                  an agreement with regard to a Change in Control or (ii)
                  otherwise occurred in connection with, or in anticipation of,
                  a Change in Control, provided that, in either such case, such
                  Change in Control actually occurs within one (1) year
                  following the Employment Termination Date.

            (d)   As used herein, 'Just Cause' shall mean:

               (i)   a judicial determination that the Participant has committed
                     fraud, misappropriation, or embezzlement against the
                     Company; or

               (ii)  a non-appealable conviction of, or entry of a plea of nolo
                     contendere for, an act by the Participant constituting a
                     felony which, as determined by the Company in good faith,
                     constitutes a crime involving moral turpitude and has
                     resulted in material harm to the Company, its subsidiaries
                     and affiliates taken as a whole.

               A termination of employment pursuant to Just Cause shall not be
            considered to be effective unless accompanied by a copy of a
            resolution duly adopted by the affirmative vote of not less than a
            majority of the Continuing Directors at a meeting of the Board of
            Directors which was called and held for the purpose of considering
            such termination, or if there are no Continuing Directors, then by
            at least three quarters  of the entire Board of Directors (after
            reasonable notice to the Participant and an opportunity for the
            Participant, together with the Participant's counsel, to be heard
            before the Board of Directors) finding that, in the good faith
            opinion of the Board of Directors, the Participant was guilty of
            conduct set forth in the preceding sentence, and specifying the
            particulars thereof in detail.  In any Board deliberations or votes
            concerning a determination under this Section, the Participant shall
            recuse himself from such deliberations and votes."

12.  Section 6.01 is restated as follows:

      "6.01 Termination of Employment.

            (a)  Voluntary Termination.

               A Participant whose employment is terminated for any reason other
            than death or retirement, including early retirement, will not be
            entitled to benefits under this Plan, except as provided in
            Subsection (b) and Section 6.04 hereof.

 
                                       6

            (b)  Involuntary Termination.

               Notwithstanding any other provision of the Plan (and except as
            discussed herein), a Participant whose employment is involuntarily
            terminated prior to his Early Retirement Date, other than for Just
            Cause, and who executes a release and discharge of the Company from
            any and all claims, demands or causes of action other than as to
            amounts or benefits due to the Participant under any plan, program
            or contract provided by, or entered into with, the Company will be
            entitled to benefits in accordance with this Subsection (b).  Such
            release and discharge shall be in such form as is prescribed by the
            Committee and shall be executed prior to the payment of any benefits
            due hereunder.  In addition, no benefits due hereunder shall be paid
            to a Participant who is required by Company guidelines to execute an
            agreement governing the assignment of patents or the disclosure of
            confidential information unless an executed copy of such agreement
            is on file with the Company.  The benefits under this Subsection (b)
            shall consist of a nonforfeitable percentage in the benefits
            calculated under Section 3.06 (including the minimum benefit defined
            under Section 3.04) equal to 1-2/3% times the number of completed
            months of Executive Service.  Such benefits shall commence
            coincident with or next following the first day of the calendar
            month in which the Participant attains age 55, or if the Participant
            elects, the benefit will be paid no later than 30 days after the
            Termination Date, in a lump sum payment of the Actuarial Equivalent
            of the age 55 retirement income determined under Section 3.06, with
            an additional reduction of such benefit by discounting it to the
            date of payment using the interest rate used in Section 1.01.  Any
            participant who also is eligible to receive benefits under Section
            6.04 shall not receive benefits hereunder but shall instead receive
            the benefits under Section 6.04."

13.  Section 6.04 is restated as follows:

      "6.04 Change in Control.

            (a)   Notwithstanding any other provisions in the Plan, any
                  Participant who terminates employment as a result of a
                  Qualifying Termination shall become fully vested upon a Change
                  in Control of the Company and shall be entitled to benefits
                  calculated as follows:

               (1)   Except for purposes of Section 1.10(b), Service and
                     Credited Service shall be increased by 36 months, with the
                     number of months credited under this Section 6.04(a)(1)
                     reduced by one month for each completed month of Service of
                     the Participant after the date of the Change in Control,
                     but not below zero.

               (2)   If at the Termination Date, the Participant has attained
                     his Normal Retirement Date, he shall be entitled to a
                     benefit calculated in accordance with Section 3.02.

               (3)   If at the Termination Date, the Participant has not
                     attained his Normal Retirement Date, or has not attained
                     his Early Retirement Date, he shall be entitled to benefits
                     calculated under Section 3.06 (including the minimum
                     benefit defined under Section 3.04).

 
                                       7

               (4)   Final Average Earnings shall be determined using the
                     greater of: (i) the amount determined under Section 1.16
                     without reference to this Section 6.04(a)(4); (ii) Earnings
                     for the first full calendar month preceding the Termination
                     Date; or (iii) Earnings for the first full calendar month
                     preceding the date of a Change in Control.

               (5)   In the case of a Participant who has not attained his Early
                     Retirement Date at the Termination Date, such benefits
                     shall commence coincident with or next following the first
                     day of the calendar month in which the Participant attains
                     age 55, or if the Participant elects, the benefit will be
                     paid no later than 30 days after the Termination Date, in a
                     lump sum payment of the Actuarial Equivalent of the age 55
                     retirement income determined under Section 3.06 with
                     additional reduction of such benefit by discounting it to
                     the date of payment using the interest rate used in Section
                     1.01.

            (b)   Notwithstanding any other provisions in the Plan, upon a
                  Change in Control and for a period of twelve (12) months
                  thereafter, any retired Participant or Beneficiary who is
                  receiving an optional form of retirement income pursuant to
                  Article IV hereof, shall have the right to elect to receive in
                  a single lump-sum cash payment an amount equal to ninety-five
                  percent (95%) of the Actuarial Equivalent of the payments of
                  such retirement income to which the Participant or Beneficiary
                  is entitled for all future periods under the Plan; provided,
                  however, that if this option is exercised, such retired
                  Participant or Beneficiary will forfeit to the Company the
                  remaining five percent 5% of the Actuarial Equivalent of such
                  payments.  Payments under this Section 6.04(b) shall be made
                  as soon as practicable, but no later than 30 days after the
                  retired Participant or Beneficiary notifies the Plan that he
                  is exercising his right to withdraw.

            (c)   The Company shall pay all reasonable legal fees and related
                  expenses incurred by a Participant in seeking to obtain or
                  enforce any payment, benefit or other right such Participant
                  may be entitled to under the Plan after a Change in Control;
                  provided, however, that the Participant shall be required to
                  repay any such amounts to the Company to the extent a court of
                  competent jurisdiction issues a final and non-appealable order
                  setting forth the determination that the position taken by the
                  Participant was frivolous or advanced in bad faith."
