Company for any reason other than. for Cause (a “Change in Control Termination”), then the Employee shall be entitled to the following severance benefits:

(a)Termination Payment upon Change in Control. The Company shall pay the Employee a lump sum cash payment, no later than thirty (30) days after the Termination Date, in an amount equal to (i) two times Employee's average annual cash compensation (including base salary and cash bonuses, but excluding the award or exercise of stock options or stock grants) for the three fiscal years (or lesser number of fiscal years if the Employee's employment has been of shorter duration) of the Company immediately preceding the Change in Control Termination, plus (ii) the amount of the Employee's earned but unused vacation time. If the Employee is a "specified employee" (within the meaning of Section 409A of the Internal Revenue Code and the regulations thereunder), and if the amount otherwise payable to the Employee under this Paragraph 2(a) during the six-month period beginning on the Termination Date exceeds two times the limitation applicable as of the Termination Date under Section 401(a)(l 7) of the Internal Revenue Code, then such excess amount shall be paid at the end of such six month period.

(b)Unpaid Annual Bonus Payment for Prior Fiscal Year upon Termination upon Change in Control. If the Termination Date occurs before a cash incentive award under the Senior Executive Incentive Plan for work performed in any preceding fiscal year has been paid, the Company shall, in addition to the payment to be made pursuant to Paragraph 2(a), pay to the Employee the amount of the Employee's cash incentive award under the Senior Executive Incentive Plan for such preceding fiscal year as soon as it is determinable and such amount shall be included in the calculation of the payment to be made pursuant to Paragraph 2(a). Notwithstanding the foregoing regarding the payment of an unpaid cash incentive award for performance in a prior fiscal year, no cash incentive award under the Senior Executive Incentive Plan or otherwise shall be paid for performance during any part of the fiscal year in which the Termination Date occurs.

3.Non-Change in Control Termination. Notwithstanding the foregoing, if the Employee's employment is terminated by the Company for any reason other than for Cause (a “Non-Change in Control Termination”), and such termination does not occur upon or within twenty-four (24) months after a Change in Control such that a Change in Control Termination shall have occurred, then the Employee shall, subject to the conditions set forth in Paragraph 4, be entitled to the following severance benefits:

(a)Non-Change in Control Termination Payment. The Company shall pay the Employee (i) an amount equal to the sum of (A) the Employee's annual base salary as of the Termination Date plus (B) the amount of the cash incentive award that was paid to the Employee under the Senior Executive Incentive Plan for work performed in the fiscal year immediately preceding the fiscal year in which the Termination Date occurs, which amount shall be payable over a period of one year beginning on the Termination Date in periodic installments in accordance with the Company's normal payroll practices, and (ii) a lump cash payment, no later than thirty (30) days after the Termination Date, in an amount equal to the Employee's earned but unused vacation time. If the Employee is a "specified employee" (within the meaning of Section 409A of the Internal Revenue Code and the regulations thereunder), and if the amount otherwise payable to the Employee under this Paragraph 3(a) during the six-month period beginning on the Termination Date exceeds two times the limitation applicable as of the Termination Date under Section 401(a)(l 7) of the Internal Revenue Code, then such excess amount shall be paid at the end of such six-month period.

(b) Unpaid Annual Bonus Payment for Prior Fiscal Year upon Non- Change in Control Termination. If the Termination Date occurs before a cash incentive award under the Senior Executive Incentive Plan for work performed in any preceding fiscal year has been paid, the Company shall, in addition to the payments to be made pursuant to Paragraph 3(a), pay to the Employee the amount of the Employee's cash incentive award under the Senior Executive Incentive Plan for such preceding fiscal year as soon as it is determinable and such amount shall be included in the calculation of the payment to be made pursuant to Paragraph 3(a). Notwithstanding the foregoing regarding the payment of an unpaid cash incentive award for performance in a prior fiscal year, no cash incentive award under the Senior Executive Incentive Plan or otherwise shall be paid for performance during any part of the fiscal year in which the Termination Date occurs.

(a)LTIP Payment. If the Termination Date occurs before the Employee receives payment of an Incentive Compensation Award, the Employee shall receive payment with respect to such Incentive Compensation Award, in the same form and at the same time as would have otherwise been payable to him or her as a Participant in the LTIP (notwithstanding the provisions of Section 11 of the LTIP) had he or she remained employed by the Company through the end of the Incentive Compensation Award Period applicable to such Incentive Compensation Award and had he or she been employed on the date on which such Incentive Compensation Award is paid. The amount payable to the Employee with respect to such Incentive Compensation Award pursuant to this Paragraph 3 shall be equal to the amount that would otherwise have been payable to the Employee with respect to such Incentive Compensation Award had the Employee remained continuously employed by the Company through the end of the Incentive Compensation Award Period and had he or she been employed on the date on which such Incentive Compensation Award is paid, multiplied by a fraction, the numerator of which is the number of full calendar years of the Incentive Compensation Award Period prior to the Termination Date, and the denominator of which is three.

(b)COBRA Premium. If the Employee elects to receive COBRA benefits upon termination the Company shall pay the premium for coverage of the Employee and the Employee's eligible spouse and/or dependents under the Company's group health plan(s) pursuant to the Consolidated Omnibus Budget Reconciliation Act for the one-year period beginning on the Termination Date.

(c)Outplacement Counseling. The Company shall provide the Employee with reasonable executive outplacement services, in accordance with Company policies for senior executives as in effect on the Termination Date.

(d)Lapse of Restrictions on Performance Based Restricted Share Awards. Notwithstanding the terms of any agreement pursuant to which performance based restricted shares awards have been granted to the Employee by the Company, all restrictions applicable to such awards shall lapse immediately upon the Termination Date if the measurement period and performance goals applicable thereto have been achieved on or before the Termination Date.

4. Condition to Receipt of Severance Benefits under Paragraph 3. As a condition to receiving any severance benefits in connection with a Change in Control Termination under Paragraph 2 or in connection with a Non-Change in Control Termination under Paragraph 3, the Employee shall execute a general waiver and release (the “Waiver and Release”) in substantially the form attached hereto

as Exhibit A. The Waiver and Release shall become effective in accordance with the rescission provisions set forth therein.

1.Benefits in Lieu of Severance Pay. The severance benefits provided for in Paragraphs 2 and 3 are in lieu of any benefits that would otherwise be provided to the Employee under any Company severance pay policy or practice and the Employee shall not be entitled to any benefits under any Company severance pay policy or practice in the event that severance benefits are paid hereunder.

2.Rights in the Event of Dispute. In the event of a Change of Control Termination, if there is a claim or dispute arising out of or relating to this Agreement or any breach thereof, regardless of the party by whom such claim or dispute is initiated, the Company shall, in connection with settlement in the Employee's favor of any such matter or upon payment of any judgment entered in the Employee's favor, upon presentation of appropriate vouchers, pay all legal expenses, including reasonable attorneys' fees, court costs, and ordinary and necessary out-of-pocket cost of attorneys, billed to and payable by the Employee or by anyone claiming under or through the Employee.

3.Other Benefits. The benefits provided under this Agreement shall, except to the extent otherwise specifically provided herein, be in addition to, and not in derogation or diminution of, any benefits that Employee or his or her beneficiary may be entitled to receive under any other contract, plan or program now or hereafter maintained by the Company, or its subsidiaries, including any and all stock options and restricted stock award agreements.

4.Effect on Employment. Neither this Agreement nor anything contained herein shall be construed as conferring upon Employee the right to continue in the employment of the Company or any of its affiliates, or as interfering with or limiting the right of the Company to terminate the Employee's employment with or without cause at any time.

5.Limitation in Action. Prior to the occurrence of a Change in Control, Employee shall have no rights under Paragraph 2 of this Agreement and the Board shall have the power and the right, within its sole discretion, to rescind, modify or amend Paragraph 2 of this Agreement without the consent of Employee. In all other cases, and notwithstanding the authority granted to the Board to exercise any discretion to rescind, modify or amend Paragraph 2 of this Agreement contained herein, the Board will not, following a Change in Control, have the power or right to exercise such authority or otherwise take any action that is inconsistent with the provisions of this Agreement.

The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation, or otherwise) to all or substantially all of the business and/or assets of the Company, to expressly assume and agree to perform its obligations under this Agreement in the same manner and to the same extent that the Company would be required to perform them if no succession had taken place unless, in the opinion of legal counsel mutually acceptable to the Company and the Employee, such obligations have been assumed by the successor as a matter of law. The Employee's rights under this Agreement shall inure to the benefit of, and shall be enforceable by, the Employee's legal representative or other successors in interest, but shall not otherwise be assignable or transferable.

7.Severability. If any provision of this Agreement or the application thereof is held invalid or unenforceable, the invalidity or unenforceability thereof shall not affect any other provisions or applications of this Agreement which can be given effect without the invalid or unenforceable provision or application.

8.Survival. The rights and obligations of the parties pursuant to this Agreement shall survive the termination of the Employee's employment with the Company to the extent that any performance is required hereunder after such termination.

10.Notices. All notices under this Agreement shall be in writing and shall be deemed effective when delivered in person (in the Company's case, to its Secretary) or 48 hours after deposit thereof in the U.S. mails, postage prepaid, addressed, in the case of the Employee, to his last known address as carried on the personnel records of the Company and, in the case of the Company, to the corporate headquarters, attention of the Secretary, or to such other address as the party to be notified may specify by written notice to the other party.
