APPENDIX E

EGTRRA CHANGES

This Appendix E is adopted to reflect certain provisions of the Economic Growth and Tax Relief Reconciliation Act of 2001 (“EGTRRA”). This Appendix E is intended as good faith compliance with the requirements of EGTRRA and is to be construed in accordance with EGTRRA and guidance issued thereunder. Except as otherwise provided, this Appendix E shall be effective as of January 1, 2002.

This Appendix E shall supersede the provisions of the Plan to the extent those provisions are inconsistent with the provisions of this Appendix.

The cost-of-living adjustment in effect for a calendar year applies to annual compensation for the determination period that begins with or within such calendar year.

All Participants who are eligible to make Salary Deferral Contributions under this Plan and who have attained age 50 before the close of the Plan Year shall be eligible to make catch-up contributions in accordance with, and subject to the limitations of, Code Section 414(v) and any uniform and non-discriminatory procedures established by the Committee. Such catch-up contributions shall not be taken into account for purposes of the provisions of the Plan implementing the required limitations of Code Sections 402(g) and 415. The Plan shall not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Code Section 401(k)(3), 401(k)(11), 401(k)(12), 410(b), or 416, as applicable, by reason of the making of such catch-up contributions.

9.1. Effective Date. This Section shall apply for purposes of determining whether the Plan is a Top-Heavy Plan under Code Section 416(g) for Plan Years beginning after December 31, 2001, and whether the Plan satisfies the minimum benefits requirements of Code Section 416(c) for such years. This Section amends Article XIV of the Plan.

9.2 Determination of Top-Heavy Status.

9.2.1 Key Employee. “Key Employee” means any Employee or former Employee (including any deceased Employee) who at any time during the Plan Year that includes the Determination Date was an officer of the Employer having annual compensation greater than $130,000 (as adjusted under Code Section 416(i)(1) for Plan Years beginning after December 31, 2002), a 5-percent owner of the Employer, or a 1- percent owner of the Employer having annual compensation of more than $150,000.

The determination of who is a Key Employee will be made in accordance with Code Section 416(i)(1) and the applicable regulations and other guidance of general applicability issued thereunder.

9.2.2 Determination of Present Values and Amounts. This Section 9.2.2 shall apply for purposes of determining the present values of accrued benefits and the amounts of account balances of Employees as of the determination date.

9.2.2.1 Distributions during Year Ending on the Determination Date.

The preceding sentence shall also apply to distributions under a terminated plan which, had it not been terminated, would have been aggregated with the Plan under Code Section 416(g)(2)(A)(i). In the case of a distribution made for a reason other than separation from service, death, or disability, this provision shall be applied by substituting “5-year period” for “1-year period.”

9.2.2.2 Employees Not Performing Services During Year Ending on the Determination Date. The accrued benefits and accounts of any individual who has not performed services for the Employer during the 1-year period ending on the Determination Date shall not be taken into account.
