     5. Article 7 of the Plan is hereby amended by adding thereto the following new Section 7.3:

7.3 The Board, in its discretion, may determine that, upon the occurrence of a Change of Control of the Company, each Option and SAR outstanding hereunder shall terminate within a specified number of days after notice to the holder, and such holder shall receive, with respect to each share of Stock subject to such Option or SAR, an amount equal to the excess of the Fair Market Value of such share of Stock immediately prior to the occurrence of such Change of Control over the exercise price per share of such Option or SAR; such amount to be payable in cash, in one or more kinds of property (including the property, if any, payable in the transaction constituting the Change of Control) or in a combination thereof, as the Board, in its discretion, shall determine. The provisions contained in the preceding sentence shall be inapplicable to an Option or SAR granted within six (6) months before the occurrence of a Change of Control if the holder of such Option or SAR is subject to the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and no exception from liability under Section 16(b) of the Exchange Act is otherwise available to such holder.

     6. Article 7 of the Plan is hereby amended by adding thereto the following new Section 7.4:

7.4 Compliance with Section 409A. Awards shall be designed, granted and administered in such a manner that they are either exempt from the application of, or comply with, the requirements of section 409A of the Code (“Section 409A”). If the Committee determines that an Award, payment, distribution, deferral election, transaction, or any other action or arrangement contemplated by the provisions of the Plan would, if undertaken or implemented, cause a holder to become subject to additional taxes under Section 409A, then unless the Committee specifically provides otherwise, such Award, payment, distribution, deferral election, transaction or other action or arrangement shall not be given effect to the extent it causes such result and the related provisions of the Plan and/or Award agreement will be deemed modified, or, if necessary, suspended in order to comply with the requirements of Section 409A to the extent determined appropriate by the Committee, in each case without the consent of or notice to the holder. The exercisability of an Option shall not be extended to the extent that such extension would subject the holder to additional taxes under Section 409A. This Section 7.4 is effective for Awards granted under the Plan that are earned and vested on or after January 1, 2005.

     7. Article 7 of the Plan is hereby amended by adding thereto the following new Section 7.5:

7.5 Duration. The Plan shall commence as of the Effective Date and shall remain in effect, subject to the right of the Board to amend or terminate the Plan at any time pursuant to Article 6, until all shares of Stock subject to it shall have been purchased or acquired according to the Plan’s provisions. However, in no event may an Award be granted under the Plan after March 20, 2017.
