AWARD DETERMINATION

4.1. Performance Goals. Prior to the beginning of each Plan Year, or as soon as practicable thereafter (but in no event more than ninety (90) days after the beginning of such Plan Year), the Committee shall, in its sole discretion, approve or establish in writing the performance goals for that Plan Year. For any performance period that is less than twelve months, the performance goals shall be established before twenty-five percent (25%) of the relevant performance period has lapsed.

The performance goals may include, without limitation, any combination of financial, non-financial and individual performance goals, as determined by the Committee, based upon: (i) the price of Stock, (ii) the market share of the Company or its Subsidiaries (or any business unit thereof), (iii) sales by the Company or its Subsidiaries (or any business unit thereof), (iv) earnings per share of Stock, (v) return on shareholder equity of the Company, (vi) costs of the Company or its Subsidiaries (or any business unit thereof), (vii) cash flow of the

The Committee shall have discretion to determine the specific targets with respect to each of these categories of performance goals. Before payment of a Bonus, the Committee shall certify that an individual has satisfied the applicable performance goal.

With respect to awards not intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee also shall have the authority to exercise subjective discretion in the determination of final awards, as well as the authority to delegate the ability to exercise subjective discretion in this respect.

The performance period with respect to which awards may be payable under the Plan shall generally be the Plan Year; provided, however, that the Committee shall have the authority and discretion to designate different performance periods under the Plan.

Prior to the beginning of each Plan Year, or as soon as practicable thereafter (but in no event more than ninety (90) days after the beginning of such Plan Year), the Committee shall approve or establish in writing the objective compensation formula or standard for that Plan Year. Such objective compensation formula or standard shall be the method for computing the amount of compensation payable to the Participant if the performance goals are attained.

4.3. Award Opportunities. Prior to the beginning of each Plan Year, or as soon as practicable thereafter (but in no event more than ninety (90) days after the beginning of such Plan Year), the Committee shall establish an Award Opportunity for each Participant.

Notwithstanding the foregoing, if awards are intended to qualify as “performance-based compensation” under Section 162(m) of the Code, such adjustment shall only be made to the extent permitted by Code Section 162(m) and the regulations and interpretative rulings thereunder, if the Committee determines that external changes or other unanticipated business conditions have materially affected the fairness of the goals and have unduly influenced the

- 13 -

Participating Employer’s ability to meet them. Further, in the event of a Plan Year of less than twelve (12) months, the Committee shall have the right to adjust the performance goals and the Award Opportunities accordingly.

4.5. Final Award Determinations. At the end of each Plan Year, Bonuses shall be computed for each Participant as determined by the Committee. Each such award shall be based upon (a) the Participant’s Target Incentive Award percentage (or such greater or lesser percentage, as appropriate), multiplied by his Base Salary, in whole or in part (or other preestablished objective compensation formula in accordance with Section 4.2), and (b) the attainment of financial, non-financial and individual performance goals. In the event that a Participant is not employed by the Participating Employer at the end of a Plan Year, no Bonus shall be payable for such Plan Year.

4.6. Limitations. A Participant’s Bonus (irrespective of any interest crediting under Section 7.1 or any Matching Contribution as provided under Section 6.2) with respect to any Plan Year shall not exceed 150 percent of the Participant’s Base Salary.

ARTICLE V

PAYMENT OF BONUS AWARDS

- 14 -

objective(s) and the satisfaction of any other material terms of the awards, and the Committee shall calculate the amount of each Participant’s Bonus for the relevant period.

5.2. Payment of Partial Awards. In the event a Participant no longer meets the eligibility criteria as set forth in the Plan during the course of a particular Plan Year, the Committee may, in its sole discretion, compute and pay a partial Bonus or no Bonus for the portion of the Plan Year that an Employee was a Participant. Notwithstanding the foregoing, in order to receive any Bonus for a Plan Year, such Participant shall be employed by a Participating Employer on January 1 of the following Plan Year.

CONTRIBUTIONS

- 16 -

7.3. Dividends.

The number of additional Restricted Stock Units credited to a Participant’s Matching Sub-Account pursuant to this Section shall be calculated by dividing (a) the product of (i) the whole number of Restricted Stock Units held in the Participant’s Matching Sub-Account as of the date the dividend is paid times (ii) the amount of such dividend with respect to each share of Stock, by (b) the Fair Market Value of the Stock on the date such dividend is paid. Restricted Stock Units shall be credited to a Participant’s Matching Sub-Account under this Section as of the date the applicable dividend is paid.

7.4. Stock Adjustments. The Committee shall adjust each Participant’s Matching Sub-Account as the Committee determines is appropriate to reflect any stock dividend, stock split, combination of shares, merger, share exchange, consolidation or any other change in the corporate structure of the Company or the Stock.

ARTICLE XII

CLAIMS PROCEDURE

The Committee shall administer a claims procedure as follows:

12.1. Initial Claim. A Participant or Beneficiary who believes himself entitled to benefits under the Plan, or such individual’s authorized representative acting on behalf of such individual (the “Claimant”), must make a claim for those benefits by submitting a written notification of his or her claim of right to such benefits. Such notification must be on the form and in accordance with the procedures established by the Committee.

12.2. Procedure for Review. The Committee shall establish administrative processes and safeguards to ensure that all claims for benefits are reviewed in accordance with the Plan document and that, where appropriate, Plan provisions have been applied consistently to similarly situated Claimants.

12.3. Claim Denial Procedure. If a claim is wholly or partially denied, the Committee shall notify the Claimant within a reasonable period of time, but not later than 90 days after receipt of the claim, unless the Committee determines that special circumstances require an extension of time for processing the claim. If the Committee determines that an extension of time for processing is required, written notice of the extension shall be furnished to the Claimant prior to the termination of the initial 90-day period. In no event shall such

- 24 -

extension exceed a period of 180 days from receipt of the claim. The extension notice shall indicate: (a) the special circumstances necessitating the extension and (b) the date by which the Committee expects to render a benefit determination. A benefit denial notice shall be written in a manner calculated to be understood by the Claimant and shall set forth: (a) the specific reason or reasons for the denial, (b) the specific reference to the Plan provisions on which the denial is based, (c) a description of any additional material or information necessary for the Claimant to perfect the claim, with reasons therefore, and (d) the procedure for reviewing the denial of the claim and the time limits applicable to such procedures, including a statement of the Claimant’s right to bring a legal action under section 502(a) of ERISA following an adverse benefit determination on review.

12.4. Appeal Procedure. In the case of an adverse benefit determination, the Claimant shall have the opportunity to appeal to the Committee for review thereof by requesting such review in writing to the Committee within 60 days of receipt of notification of the denial. Failure to submit a proper application for appeal within such 60 day period will cause such claim to be permanently denied. The Claimant shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claim. A document, record or other information shall be deemed “relevant” to a claim in accordance with 29 C.F.R. §2560.503-1(m)(8). The Claimant shall also be provided the opportunity to submit written comments, documents, records and other information relating to the claim for benefits. The Committee shall review the appeal taking into account all comments, documents, records and other information submitted by the Claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination.

12.5. Decision on Appeal. The Committee shall notify a Claimant of its decision on appeal within a reasonable period of time, but not later than 60 days after receipt of the Claimant’s request for review, unless the Committee determines that special circumstances require an extension of time for processing the appeal. If the Committee determines that an extension of time for processing is required, written notice of the extension shall be furnished to the Claimant prior to the termination of the initial 60-day period. In no event shall such extension exceed a period of 60 days from the end of the initial period. The extension notice shall indicate: (a) the special circumstances necessitating the extension and (b) the date by which the Committee expects to render a benefit determination. An adverse benefit decision on appeal shall be written in a manner calculated to be understood by the Claimant and shall set forth: (a) the specific reason or reasons for the adverse determination, (b) the specific reference to the Plan provisions on which the denial is based, (c) a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of all documents, records, and other information relevant to the Claimant’s claim (the relevance of a document, record or other information will be determined in accordance with 29 C.F.R. §2560-1(m)(8)) and (d) a statement of the Claimant’s right to bring a legal action under section 502(a) of ERISA.

13.1. The Board or the Committee shall have the right to modify or amend the Plan at any time and from time to time, and the Board shall have the right to discontinue or terminate the Plan at any time and from time to time; provided, however, that no modification, amendment, discontinuance or termination may, without the consent of a Participant, adversely affect the rights of such Participant to amounts previously credited to his Account or reduce the right of such Participant to a payment or distribution hereunder which he has already earned and to which he is otherwise entitled.
