CONTRIBUTIONS

Unless otherwise provided in Section 4.01(b) for a given Plan Year, the annual Retirement Contribution for a Participant shall be the Retirement Contribution Percentage specified in the following table (based on the sum of the Participant’s age and Years of Service), multiplied by the sum of the Participant’s Base Salary paid during such Plan Year plus Bonus Compensation paid during such Plan Year (notwithstanding the fact that the Bonus Compensation relates to services performed in a prior year).

     (b) Enhanced Contributions . Notwithstanding Section 4.01(a), and in lieu of the contributions provided thereunder, for a given Plan Year, the Retirement Account of a Participant employed by the Company as of December 31, 2008, and whose age plus Years of Service as of such date totaled at least 55, shall be credited with annual Retirement Contributions equal to the Retirement Contribution Percentage specified in the following table (based on the Participant’s age and Years of Service) multiplied by the sum of the Participant’s Base Salary paid during such Plan Year plus Bonus Compensation paid during such Plan Year (notwithstanding the fact that the Bonus Compensation relates to services performed in a prior year).

     (c) Determination of Age and Years of Service . For purposes of this Article IV, age and Years of Service are determined as of the last day of each Plan Year, fractional years shall not be counted, and there shall be no rounding to the next highest age or Year of Service.

     (d) Effect of Termination of Employment . A Participant shall not be entitled to receive a credit to his or her Retirement Account with respect to a Plan Year if he or she terminates employment prior to the date on which Retirement Contributions are credited to the Accounts of Participants in accordance with Section 4.01(e), unless the termination was due to the Participant’s Disability or Death, or termination by the Company without Cause, or due to a voluntary termination of employment after attaining age 65 or following a Change of Control.

     (e) Timing of Contributions . A Participant’s Retirement Contribution with respect to a given Plan Year of participation in the Plan shall be credited to the Participant’s Retirement Account in the first quarter following the end of such Plan Year ( e.g. by March 31, 2009 for the 2008 Plan Year).

     (f) First Year of Participation . Contributions with respect to the Plan Year in which a Participant becomes a Participant shall be based on the Participant’s Base Salary and Bonus Compensation for the entire Plan Year. However, in accordance with Treasury Regulation Section 1.409A-2(a)(7), a new Participant’s Retirement Contributions with respect to the first year of participation in the Plan shall not exceed (in absolute terms) the Participant’s Base Salary and other compensation earned during the Plan Year after a Participation Agreement is filed in accordance with Section 7.04. The previous sentence shall not apply to the 2008 Plan Year, in accordance with transition guidance issued by the Internal Revenue Service in Notice 2007-86.

     (g) Sample Retirement Contribution Calculation . Assume that Executive A is age 55 and has 10 Years of Service as of December 31, 2008. His 2008 Base Salary was $300,000 and he received a bonus in February 2008 of $200,000.

               Because his age plus Years of Service total at least 55, Executive A is eligible for an Enhanced Contribution. His contribution for the 2008 Plan Year will be $75,000, determined as follows:

     4.02 Discretionary Contributions . The Compensation Committee may, in its sole and absolute discretion, allocate Discretionary Contributions to a Participant’s Accounts if and when it deems appropriate (for example, if the Company wishes to reward long-service executives or provide additional incentives to recruit executives). Discretionary Contributions may be subject to special provisions, as specified by the Compensation Committee, including (but not limited to) special vesting and form of payment provisions. Declarations of awards of Discretionary Contributions shall be treated as a part of this Plan document and memorialized on Appendix C to the Plan.

     4.03 Withholding on Contributions . To the extent that the Company is required to withhold any taxes or other amounts from a contribution under the Plan pursuant to any state, Federal or local law, such amounts shall be taken out of other compensation eligible to be paid to the Participant, unless otherwise provided by the Administrative Committee pursuant to Section 7.07.

ARTICLE V
