Decisions of the Committee shall be final and binding on all persons who have an interest in this Plan. 1.3 Participation in the Plan. Directors of the Company who are not employees of the Company or any of its subsidiaries are eligible to participate in this Plan. 2. STOCK SUBJECT TO THE PLAN 2.1 Number of Shares. The maximum number of shares of the Company's $2.50 par value Common Stock ("Common Stock" or "Shares") which may be issued pursuant to options granted under this Plan shall be one hundred thousand (100,000) Shares, subject to adjustment as provided in Section 4.4. 2.2 Nonexercised Shares.

Upon the exercise of an option, the Company may issue new Shares or reissue Shares previously repurchased by or on behalf of the Company. 3. OPTIONS 3.1 Option Grant Dates. Options shall be granted automatically to each participating director on December 31 of each year (or, if December 31 is not a business day, on the immediately preceding business day) (the "Grant Date"). 3.2 Option Price. The purchase price per share for the Shares covered by each option shall be $2.50 (the "Option Price"). 3.3 Number of Option Shares. The number of Shares subject to options granted to each participating director on each Grant Date will be the aggregate number of Shares determined by the following formulas: 3.3.1 Elected Portion of Annual Retainer and Meeting Fee Shares. The number of option Shares equal to the nearest whole number determined by the following formula: Elected Portion of Annual Retainer Number and Meeting Fees = of (Fair Market Value - $2.50) Option Shares 3.3.2 Dividend Equivalent Shares. The number of option Shares equal to the nearest whole number determined by the following formula: Dividend Equivalent = Number of (Fair Market Value - $2.50) Option Shares 3.3.3 Definitions. For purposes of determining the number of Shares granted under this Section 3.3, the following definitions will apply: 3.3.3.1 "Annual Retainer." The dollar amount of compensation paid to eligible directors each year which is identified by the Company as an annual retainer. 3.3.3.2 "Meeting Fees." The amount of compensation, in excess of the Annual Retainer, paid to eligible directors for their services as directors of the Company, including but not limited to fees earned for service as committee chairpersons and for meeting participation, but excluding amounts paid as reimbursement for actual expenses. 3.3.3.3 "Dividend Equivalent." The aggregate dollar value, determined each year, equal to the product of (i) the number of Shares subject to options held by a director pursuant to this Plan on each respective Record Date during the year plus one-half the number of Shares to be granted under Sections 3.3.1 and 3.3.2 for the year in which this calculation is being made, multiplied by (ii) the value of the dividend per Share paid by the Company for each respective Record Date. 3.3.3.4 "Elected Portion of Annual Retainer and Meeting Fees." A dollar amount determined each year for each director equal to the dollar amount of both the percentage of the Annual Retainer, if any, and the percentage of Meeting Fees, if any, which the director has irrevocably elected, in writing, to have paid in the form of options granted under this Plan. This written election must be received by the secretary of the Company on or before December 31 of each year and shall specify a percentage, up to 100%, of the director's Annual Retainer and a percentage, up to 100%, of the director's Meeting Fees for the following year to be paid in the form of options under this Plan; provided, however, that in the initial year of the Plan's operation a director's written election must be received by the secretary of the Company on or before February 28, 1992, and shall be effective only for Annual Retainer and Meeting Fee amounts earned during the period April 1, 1992, through December 31, 1992. Eligible directors initially elected or appointed to office as directors of the Company after adoption of this plan may make a written election under this paragraph within 30 days following their initial election or appointment to office, which election shall be effective for Annual Retainer and Meeting Fee amounts earned during the calendar year of their initial election or appointment to office. 3.3.3.5 "Fair Market Value."

For purposes of this Section 3.4, the amount of the Annual Retainer shall be prorated through the date of termination. 3.5 Written Agreements. Each grant of an option under this Plan shall be evidenced by a written agreement, which shall com- ply with and be subject to the terms and conditions contained in this Plan. 3.6 Nonstatutory Stock Options.

A director, by written notice to the Company, may designate one or more persons (and from time to time change such designation), including his or her legal representative, who, by reason of the director's death, shall acquire the right to exercise all or a portion of an option granted under this Plan.
