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. 
 
1. Increase in Compensation Limit 
 
The annual compensation of each Participant taken into account in determining
allocations for any Plan Year beginning after December 31, 2001, shall not exceed $200,000, as adjusted for cost-of-living increases in accordance with Code Section 401(a)(17)(B). “Annual compensation” means compensation during the Plan
Year or such other consecutive 12-month period over which compensation is otherwise determined under the Plan (the “determination period”). 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. 
 
2. Salary Deferral Contribution Limitation 
 
No Participant shall be permitted to have Salary Deferral Contributions made under this Plan, or any other qualified plan maintained by the Employer during any taxable year, in excess of the dollar limitation contained in Code

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.

year. 
 
5. Limitations on Contributions

 
Except to the extent permitted under Section 3 of this
Appendix E and Code Section 414(v), if applicable, the annual addition that may be contributed or allocated to a Participant’s Account under the Plan for any Limitation Year beginning after December 31, 2001 shall not exceed the lesser of
$40,000, as adjusted for increases in the cost-of-living under Code Section 415(d) or 100 percent of the Participant’s compensation, within the meaning of Code Section 415(c)(3), for the limitation year. 
 
6. Direct Rollovers of Plan Distributions

amounts transferred into such plan from this Plan. The definition of Eligible Retirement Plan shall also apply in the case of a distribution to a surviving spouse, or to a spouse or former spouse who is the alternate payee under a qualified domestic
relation order, as defined in Code Section 414(p). 
 
6.3. Modification of Definition of Eligible Rollover Distribution to Exclude Hardship Distributions. For purposes of the direct rollover provisions in Section 6.10 of the Plan, any amount that is distributed on account of
hardship as provided in Section 6.17 shall not be an Eligible Rollover Distribution and the distributee may not elect to have any portion of such a distribution paid directly to an Eligible Retirement Plan.

otherwise be includible in gross income. 
 
8. Repeal of
Multiple Use Test 
 
The multiple use test described in
Treasury Regulation section 1.401(m)-2 and Section 5.7(c) of the Plan shall not apply for Plan Years beginning after December 31, 2001. 
 

E-3 

 
9. Modification of
Top-Heavy Rules 
 
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. For this purpose, “annual compensation” means compensation within the meaning of Code Section 415(c)(3). 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 present values of accrued benefits and the amounts of account balances of an Employee as of the Determination Date shall be increased by the distributions
made with respect to the Employee under the Plan and any plan aggregated with the Plan under Code Section 416(g)(2) during the 1-year period 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. 
 
9.3. Minimum Benefits. Employer Matching Contributions shall be taken into account for purposes of satisfying the minimum contribution requirements of Code Section 416(c)(2) and the Plan. The
preceding sentence shall apply with respect to Employer Matching Contributions under the Plan or if applicable, another plan of the Employer that provides the minimum contribution requirement. Employer Matching 
 

E-4 

Contributions that are used to satisfy the minimum contribution requirements shall be
treated as Employer Matching Contributions for purposes of the actual contribution percentage test and other requirements of Code Section 401(m).
