3.

By adding the following new sentence to the end of the paragraph of the Agreement captioned “Change in Control”:

4.

By deleting the paragraph of the Agreement captioned “Severance” in its entirety and substituting the following:

     “Severance. Subject to the provisions of paragraph 9, if your employment is terminated other than by you voluntarily or for death, disability, or non-performance of your duties, subject to your timely execution and delivery of a general release and such other documents as the Company may reasonably request: (a) you will be paid a severance benefit in an amount equal to two times the total of your then current annual base salary plus your bonus for the immediately preceding year, provided that your severance, if any, shall be paid in a lump sum within 60 days after your termination of employment; (b) subject to Board and/or Committee approval, all your outstanding awards under the Plan (or any other similar benefit plan or compensation program or arrangement of the Company or its subsidiaries) may vest and/or become exercisable on the date of your termination, provided that the time or schedule of any payment of your outstanding awards under the Plan (or any other similar benefit plan or compensation program or arrangement of the Company or its subsidiaries) that provides for the ‘deferral of compensation’ (as such term is described under Code Section 409A), may not be accelerated except as otherwise permitted under Code Section 409A and the guidance and Treasury regulations issued thereunder; (c) vested stock options you hold will remain exercisable for a period of not less than 90 days from your termination (but not longer than the original expiration date of the applicable option); and (d) the Company will continue to provide to you, for one year following the date of the termination of your employment, health benefits amounting to no less than the amount of health benefits you receive at the time your employment commences.

6.

By adding the following two new paragraphs immediately at the end of the Agreement:

     “Reimbursements and In-kind Benefits. Any expense reimbursement under this Agreement which provides for the ‘deferral of compensation’ (as such

term is described under Code Section 409A) shall be made promptly upon your presentation to the Company of evidence of the fees and expenses incurred by you and in all events on or before the last day of the taxable year following the taxable year in which such expense was incurred by you; and no such reimbursement or the amount of expenses eligible for reimbursement, or in-kind benefits provided, in any taxable year shall in any way affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year, except for any limit on the amount of expenses that may be reimbursed under an arrangement described in Section 105(b) of the Code. Additionally, any right to expense reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit.

     Code Section 409A. The parties intend that this Agreement and the benefits provided hereunder qualify for an exemption from Code Section 409A, provided, however, that if the Agreement and the benefits provided hereunder are not so exempt, they are intended to comply with Code Section 409A to the extent applicable thereto. Notwithstanding any provision of the Agreement to the contrary, the Agreement shall be interpreted and construed consistent with this intent, provided that the Company shall not be required to assume any increased economic burden in connection therewith. Although the Company intends to administer the Agreement so that the Agreement and the benefits provided hereunder are exempt from Code Section 409A or otherwise comply with the requirements of Code Section 409A, the Company does not represent or warrant that the Agreement will comply with Code Section 409A or any other provision of federal, state, local, or non-United States law. Neither the Company, its subsidiaries, nor their respective directors, officers, employees or advisers shall be liable to you (or any other individual claiming a benefit through you) for any tax, interest, or penalties you may owe as a result of compensation paid under the Agreement, and the Company and its subsidiaries shall have no obligation to indemnify or otherwise protect you from the obligation to pay any taxes pursuant to Code Section 409A.”

7.

Except as modified herein the Agreement shall remain in full force and effect.

          IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of the date first above written.
