Any such adjustment shall be conclusive and binding for all purposes of the Plan. SECTION 6: STOCK OPTIONS. 6.1: The Corporation may award options to purchase common stock or Restricted Stock of the Corporation (hereinafter referred to as "Stock Option Awards") to such Participants as the Committee, or the Chief Executive Officer of the Corporation, if the Committee in its discretion delegates the right to allocate awards pursuant to Section 4, authorizes and under such terms as the Committee establishes. The Committee shall determine with respect to each Stock Option Award and designate in the grant whether a Participant is to receive an Incentive Stock Option or a Non-Qualified Stock Option. -6- 6.2: The option price of each share of stock subject to a Stock Option Award shall be specified in the grant, but in no event shall the exercise price be less than the closing price of the common stock of the Corporation on the date the award is authorized as reported in the New York Stock Exchange-Composite Transactions.

Following transfer, any such Stock Options shall continue to be subject to the same terms and conditions as were applicable immediately prior to transfer, provided that for purposes of Section 6.4 hereof, the term "Participant" shall be deemed to refer to the transferee. The events of death, disability, Retirement and termination of employment in the Plan hereof shall continue to be applied with respect to the original Participant, following which the Stock Options shall be exercisable by the transferee only to the extent and for the periods specified in Sections 6.3(a) and (c) hereof.

Such an election shall be subject to the following: (a) the election shall be made in such manner as may be prescribed by the Committee and the Committee shall have the right, in its discretion, to disapprove such election; and (b) the election shall be made prior to the date to be used to determine the tax to be withheld and shall be irrevocable. The value of any share of common stock to be withheld by the Corporation or delivered to the Corporation pursuant to this Section 6.7 shall be the Market Price on the date to be used to determine the amount of tax to be withheld. SECTION 7: EXERCISE PAYMENTS. 7.1: The Committee may, in its discretion, grant to Participants holding stock options the right to receive Exercise Payments relating to such number of shares covered by the Participant's stock options as the Committee determines in its discretion.

Exercise Payments shall be paid within 20 business days following the exercise of a related stock option; provided, however, that payment may be deferred by the Committee, in its discretion, to such date and under such terms and conditions as the Committee may determine. 7.3: Exercise Payments shall be paid only upon the exercise of related stock options which are exercised by the Participant while an active Employee; provided, however, that in the case of a Participant's death, Exercise Payments will be paid if the related stock options are exercised within nine months after death, but before the expiration of the stock option's term. In the case of a Participant's Retirement, any Exercise Payments awarded to the Participant will be paid if the stock options are exercised within the later of (i) three months after Retirement or (ii) three months after such options became exercisable, but before the expiration of the term of the stock option.

The Committee, in its discretion, may also make a cash payment to a Participant granted shares of stock or Restricted Stock under the Plan to allow such Participant to satisfy tax obligations arising out of receipt of the stock or -11- Restricted Stock. Alternatively, the terms of the stock or Restricted Stock grant may allow for the Participant to satisfy tax withholding obligations by delivering whole shares of common stock of the Corporation to the Corporation; the value of any shares of common stock delivered in payment of tax withholding obligations shall be its Market Price on the date to be used to determine the amount of tax to be paid. 8:2. Notwithstanding any provision in this Plan to the contrary, no more than 20% of the maximum number of shares of stock available for award under this Plan shall be granted to Participants as Restricted Stock. 8:3. A grant of Restricted Stock pursuant to this Section 8 shall be subject to a minimum vesting period of at least three (3) years, or such longer period as the Committee may, in its sole discretion, determine; provided, however, that the Committee may grant up to three hundred thousand (300,000) shares of Restricted Stock with a vesting period of less than three (3) years. In the event that a Participant terminates employment with the Corporation prior to the date that the Restricted Stock satisfies a vesting period, such Restricted Stock shall be forfeited except (i) in the case of the Participant's death, disability or Retirement, (ii) in the case of a Participant's termination of employment by the Corporation other than for cause, (iii) in the case of a Change in Control of the Corporation, or (iv) if the Committee determines it is in the best interests of the Corporation to permit individual exceptions. -12- SECTION 9: PERFORMANCE AWARDS. 9.1: The Committee may grant, either alone or in addition to other awards granted under the Plan, awards of stock and other awards that are valued in whole or in part by reference to, or are otherwise based on, the market value of the common stock, Restricted Stock or other securities of the Corporation ("Performance Awards") to such Participants as the Committee, or the Chief Executive Officer of the Corporation, if the Committee in its discretion delegates the right to allocate awards pursuant to Section 4, authorizes and under such terms as the Committee establishes.
