SECTION 3. AWARDS

     (a) Performance Criteria. The Committee shall establish the performance objective or objectives that must be satisfied in order for a Participant to receive an award for a Performance Period; provided that to the extent Section 162(m) is applicable to the Company and the Plan, and for those awards intended to qualify as performance-based compensation under Section 162(m), the Committee shall establish the objective or objectives that must be satisfied in order for a Participant to receive an award for a Performance Period prior to the 91^st day of the Performance Period (or such other date as may be required or permitted under Section 162(m)) but not later than the date on which 25% of the performance period has lapsed. When Section 162(m) is applicable to

the Company and the Plan, unless the Committee determines at the time of grant not to qualify the award as performance-based compensation under Section 162(m), any such performance objectives will be based upon the relative or comparative achievement of one or more of the following criteria, whether in absolute terms or relative to the performance of one or more similarly situated companies or a published index covering the performance of a number of companies, as determined by the Committee for the Performance Period: earnings before interest, taxes, depreciation and amortization; operating earnings; net earnings; income; earnings before interest and taxes; total shareholder return; return on the Company’s assets; increase in the Company’s earnings or earnings per share; revenue growth; share price performance; return on invested capital; operating income; pre- or post-tax income; net income; economic value added; profit margins; cash flow; improvement in or attainment of expense or capital expenditure levels; improvement in or attainment of working capital levels; return on equity; debt reduction; gross profit; market share; cost reductions; workforce satisfaction and diversity goals; workplace health and safety goals; employee retention; completion of key projects and strategic plan development and/or implementation; job profit or performance against a multiplier; or, in the case of persons who are not Covered Employees, such other criteria as may be determined by the Committee. Performance objectives may be established on a Company-wide basis or with respect to one or more business units, divisions, Subsidiaries, or products; and in either absolute terms or relative to the performance of one or more comparable companies or an index covering multiple companies.

When establishing performance objectives for a Performance Period, the Committee may exclude any or all “extraordinary items” as determined under U.S. generally accepted accounting principles and as identified in the financial statements, notes to the financial statements or management’s discussion and analysis in the annual report, including, without limitation, the charges or costs associated with restructurings of the Company or any Subsidiary, discontinued operations, extraordinary items, capital gains and losses, dividends, share repurchase, other unusual or non-recurring items, and the cumulative effects of accounting changes. Except in the case of awards intended to qualify as performance-based compensation under Section 162(m), the Committee may also adjust the performance objectives for any Performance Period as it deems equitable in recognition of unusual or non-recurring events affecting the Company, changes in applicable tax laws or accounting principles, or such other factors as the Committee may determine (including, without limitation, any adjustments that would result in the Company paying non-deductible compensation to a Participant).

     (b) Maximum Amount Payable. If the Committee certifies in writing that any of the performance objectives established for the relevant Performance Period under Section 3(a) has been satisfied, each Participant who is employed by the Company or one of its Subsidiaries on the last day of the Performance Period for which the award is payable shall be entitled to receive an annual award in an amount not to exceed US $5,000,000. If a Participant’s employment terminates for any reason other than for cause (including, without limitation, his death, disability, retirement under the terms of any retirement plan maintained by the Company or a Subsidiary or Company Approved Departure) prior to the last day of the Performance Period for which the award is payable, the maximum award payable to such Participant under the preceding sentence shall be multiplied by a fraction, the numerator of which is the number of days that have elapsed during the Performance Period in which the termination occurs prior to and including the date of the Participant’s termination of employment and the denominator of which is the total number of days in the Performance Period.

     (c) Termination of Employment. Unless otherwise determined by the Committee in its sole discretion at the time the performance criteria are selected for a particular Performance Period in accordance with Section 3(a), if a Participant’s employment terminates for any reason prior to the date on which the award is paid hereunder, such Participants shall forfeit all rights to any and all awards that have not yet been paid under the Plan; provided that if a Participant’s employment terminates as a result of death, Disability or Company Approved Departure, the Committee shall give consideration at its sole discretion to the payment of a partial award with regard to the portion of the Performance Period worked. Notwithstanding the foregoing, if a Participant’s employment terminates for any reason prior to the date on which the award is paid hereunder, the Committee, in its discretion, may waive any forfeiture pursuant to this Section 3 in whole or in part but, to the extent Section 162(m) is applicable to the Company and the Plan, may not waive satisfaction of the performance objectives with respect to any Covered Employee.

     (d) Negative Discretion. Notwithstanding anything else contained in Section 3(b) to the contrary, the Committee shall have the right, in its absolute discretion, (i) to reduce or eliminate the amount otherwise payable to any Participant under Section 3(b) based on individual performance or conduct or any other factors that the Committee, in its discretion, shall deem appropriate and (ii) to establish rules or procedures that have the effect of limiting the amount payable to each Participant to an amount that is less than the maximum amount otherwise authorized under Section 3(b).

     (e) Affirmative Discretion. Notwithstanding any other provision in the Plan to the contrary (including, without limitation, the maximum amounts

payable under Section 3(b)), but subject in the case of awards paid in shares of the Company’s Common Stock or other awards under the Equity Incentive Plan to the maximum number of shares available for issuance under the Equity Incentive Plan, (i) the Committee shall have the right, in its discretion, to grant any annual award in cash, in shares of the Company’s Common Stock, in other awards under the Equity Incentive Plan or in any combination thereof, to any Participant (except for a Participant who is a Covered Employee, to the extent Section 162(m) is applicable to the Company and the Plan) for the year in which the amount paid would ordinarily be deductible by the Company for federal income tax purposes in an amount up to the maximum award payable under Section 3(b), based on individual performance or any other criteria that the Committee deems appropriate and (ii) in connection with the hiring of any person who is or becomes a Covered Employee, the Committee may provide for a minimum award amount in any Performance Period, regardless of whether performance objectives are attained.

SECTION 4. PAYMENT

     Except as otherwise provided hereunder, payment of any award amount determined under Section 3 shall be made to each Participant as soon as practicable after the Committee certifies that one or more of the applicable performance objectives have been attained (or, in the case of any award payable under the provisions of Section 3(d), after the Committee determines the amount of any such award) and in any event no later than two and a half months after the end of the fiscal year in which the Performance Period ends. The Committee shall determine whether any bonus payable under the Plan is payable in cash, in shares of Common Stock (including, but not limited to, restricted common stock or restricted stock units) or other awards under the Equity Incentive Plan, or in any combination thereof. The Committee shall have the right to impose whatever conditions it deems appropriate with respect to the award of shares of Common Stock or other awards, including conditioning the vesting of such shares or other awards on the performance of additional service.

SECTION 5. GENERAL PROVISIONS

     (a) Administration. The Committee shall be responsible for the administration of the Plan; provided that, in no event shall the Plan be interpreted in a manner that would cause any award intended to be qualified as performance-based compensation under Section 162(m) to fail to so qualify. The Committee shall establish the performance objectives for any fiscal year or other Performance Period determined by the Committee in accordance with Section 3 and certify whether such performance objectives have been obtained. The Committee may prescribe, amend and rescind rules and regulations relating to the administration of the Plan and make all other determinations necessary or advisable for the administration and interpretation of the Plan. Any authority exercised by the

Committee under the Plan shall be exercised by the Committee in its sole discretion. Determinations, interpretations or other actions made or taken by the Committee under the Plan shall be final, binding and conclusive for all purposes and upon all persons.

     (b) Delegation by the Committee. All of the powers, duties and responsibilities of the Committee specified in this Plan may be exercised and performed by the Committee or any duly constituted committee thereof to the extent authorized by the Committee to exercise and perform such powers, duties and responsibilities, and any determination, interpretation or other action taken by such committee shall have the same effect hereunder as if made or taken by the Committee; provided that, to the extent Section 162(m) is applicable to the Company and the Plan, the Committee shall in no event delegate its authority with respect to the compensation of any Covered Employee.

     (c) Tax Withholding. The Company shall have the power to withhold, or to require the Participant to remit to the Company, an amount in cash sufficient to satisfy all U.S. federal, state, local and any non-U.S. withholding tax or other governmental tax, charge or fee requirements in respect of any payment under the Plan.

     (e) Unfunded Plan; Plan Not Subject to ERISA. The Plan is an unfunded plan and Participants shall have the status of unsecured creditors of the Company. The Plan is not intended to be subject to the Employee Retirement Income and Security Act of 1974, as amended.

     (f) Freedom of Action. Nothing in the Plan shall be construed as limiting or preventing the Company or any of its affiliates from taking any action that it deems appropriate or in its best interest (as determined in its sole and absolute discretion) and no Participant (or person claiming by or through a Participant) shall have any right relating to the diminishment in the value of any award or any associated return as a result of any such action. The foregoing shall not constitute a waiver by a Participant of the terms and provisions of the Plan.

     (g) Forfeiture of Award Amounts.

(i) Forfeiture for Financial Reporting Misconduct. If the Company is required to prepare an accounting restatement due to material noncompliance by the Company with any financial

reporting requirement under the securities laws, (x) with respect to any Participant who either knowingly or grossly negligently engaged in the misconduct or knowingly or grossly negligently failed to prevent the misconduct as determined by the Committee or is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, such Participant shall forfeit and disgorge to the Company any award amounts (A) received during the twelve (12)-month period following the filing of the financial document embodying such financial reporting requirement or (B) earned based on the materially non-complying financial reporting, and (y) with respect to any Participant who is a current or former executive officer of the Company (as defined under the Securities Exchange Act of 1934) who received incentive compensation under the Plan during the three-year period preceding the date on which the Company is required to prepare such accounting restatement, based on erroneous data, in excess of what would have been awarded or paid to such Participant under such accounting restatement, such Participant shall forfeit and disgorge to the Company such excess incentive compensation.

(ii) Forfeiture under Applicable Laws or Regulations. In addition to forfeiture for the reasons specified in subsection (i) of this Section 5(g), the Participant shall forfeit and disgorge to the Company any award amounts to the extent required by applicable law or regulations in effect on or after the effective date of the Plan.

     (i) Amendment or Alteration. Notwithstanding Section 5(a), the Board or the Committee may at any time amend, suspend, discontinue or terminate the Plan; provided that no such action shall be effective without approval by the shareholders of the Company to the extent necessary to continue to qualify the amounts payable hereunder to Covered Employees as performance-based compensation under Section 162(m).
