The Committee shall consist of two or more members, each of whom shall qualify as a "non-employee director," as the term (or similar or successor term) is defined by Rule 16b-3, and as an "outside director" within the meaning of Code Section 162(m) and regulations thereunder. 2. Section 4.1 is amended to read: 4.1 Administration. The Committee shall be responsible for the administration of the Plan. The Committee, by majority action thereof (whether taken during a meeting or by written consent), is authorized to interpret the Plan, to prescribe, amend, and rescind rules and regulations relating to the Plan, to provide for conditions and assurances deemed necessary or advisable to protect the interests of the Company, and to make all other determinations necessary or advisable for the administration of the Plan, but only to the extent not contrary to the express provisions of the Plan. Determinations, interpretations, or other actions made or taken by the Committee pursuant to the provisions of the Plan shall be final and binding and conclusive for all purposes and upon all persons whomsoever. To the extent deemed necessary or advisable for purposes of Rule 16b-3 or otherwise, the Board may act as the Committee hereunder. 3.

Such numbers of shares shall be subject to adjustment upon occurrence of any of the events described in Section 5.3. The shares to be delivered under the Plan may consist, in whole or in part, of authorized but unissued Stock or treasury Stock, not reserved for any other purpose. 4.

Further, all Options granted to a Participant under the Plan shall be exercisable during his lifetime only by such Participant. Notwithstanding the foregoing, the Committee may, in its discretion, authorize all or a portion of the Options (other than Incentive Stock Options) granted to a Participant to be on terms which permit transfer by such Participant to: (a) the spouse, children or grandchildren of the Participant ("Immediate Family Members"); (b) a trust or trusts for the exclusive benefit of such Immediate Family Members, or; (c) a partnership in which such Immediate Family Members are the only partners, 2 provided that: (i) there may be no consideration for any such transfer; (ii) the Award Agreement pursuant to which such Options are granted expressly provides for transferability in a manner consistent with this Section 7.10; and (iii) subsequent transfers of transferred Options shall be prohibited except those in accordance with Section 11. Following transfer, any such 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 11 hereof the term "Participant" shall be deemed to refer to the transferee. The provisions of Sections 7 and 13 relating to the period of exercisability and expiration of the Option shall continue to be applied with respect to the original Participant, and the Options shall be exercisable by the transferee only to the extent, and for the periods, set forth in said Sections 7 and 13. 6.

With respect to withholding required upon the exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock, or upon any other taxable event arising as a result of awards granted hereunder, Participants may elect to satisfy the withholding requirement, in whole or in part, by having the Company withhold shares of Stock having a Fair Market Value on the date the tax is to be determined equal to the minimum statutory total tax which would be imposed on the transaction. All such elections shall be irrevocable, made in writing, signed by the Participant, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate. 3 * * * * * The foregoing Third Amendment to the 1989 Omnibus Stock and Incentive Plan was duly adopted and approved by the Board of Directors of the Company on May 21, 1997 and shall become effective as of such date.

Section 7.5 is amended to read: 7.5 Payment. Options shall be exercised by the delivery of a written notice of exercise to the Company, setting forth the number of shares of Stock with respect to which the Option is to be exercised, accompanied by full payment for the Stock. The Option Price upon exercise of any Option shall be payable to the Company in full either: (a) in cash or its equivalent (including, for this purpose, the proceeds from a cashless exercise as permitted under Federal Reserve Board's Regulation T, or other borrowed funds), (b) by tendering previously-acquired Stock having an aggregate Fair Market Value at the time of exercise equal to the total Option price (including, for this purpose, Stock deemed tendered by affirmation of ownership), (c) by any other means which the Committee determines to be consistent with the Plan's purpose and applicable law, or (d) by a combination of (a), (b), and (c).

With respect to withholding required upon the exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock, or upon any other taxable event arising as a result of awards granted hereunder, Participants may elect to satisfy the withholding requirement, in whole or in part, by having the Company withhold shares of Stock having a Fair Market Value on the date the tax is to be determined equal to the minimum statutory total tax which would be imposed on the transaction; provided, however, that in the event a deferral election is in effect with respect to the shares deliverable upon exercise of an Option, then the Participant may only elect to have such withholding made from the Stock tendered to exercise such Option.
