“Award” shall mean an award to which a Participant may be entitled under the Plan if the performance goals for a Performance Period are satisfied. An Award may be expressed in U.S. dollars or pursuant to a formula that is consistent with the provisions of the Plan.

“Board” shall mean the Board of Directors of the Company.

3.1.General. The Plan shall be administered by the Committee, which shall have the full power and authority to interpret, construe and administer the Plan and Awards granted hereunder (including in each case reconciling any inconsistencies, correcting any defaults and addressing any omissions). The Committee’s interpretation, construction and administration of the Plan and all its determinations hereunder shall be final, conclusive and binding on all persons for all purposes.

3.2.Powers and Responsibilities. The Committee shall have the following discretionary powers, rights and responsibilities in addition to those described in Section 3.1.

3.3.Delegation of Power. The Committee may delegate some or all of its power and authority hereunder to the Chief Executive Officer or other executive officer of the Company as the Committee deems appropriate; provided, however, that with respect to any person who is a “covered employee” within the meaning of Section 162(m) of the Code or who, in the Committee’s judgment, is likely to be a covered employee at any time during the applicable Performance Period or during any period in which an Award may be paid following a Performance Period, only the Committee shall be permitted to (a) designate such person to participate in the Plan for such Performance Period, (b) establish performance goals and Awards for such person, and (c) certify the achievement of such performance goals.

4.1.Establishing Performance Goals. The Committee shall establish within the Applicable Period of each Performance Period one or more objective performance goals (the outcome of which, when established, shall be substantially uncertain) for each Participant or for any group of Participants (or both). The Committee may, in its discretion, also establish within the Applicable Period of each Performance Period one or more subjective performance goals for each Participant. Objective performance goals shall be based exclusively on one or more of the following objective corporate-wide or subsidiary, division, operating unit or individual measures: earnings per share; adjusted earnings per share; earnings before interest and taxes (“EBIT”); earnings before interest, taxes, depreciation and amortization (“EBITDA”); earnings as determined other than in accordance with generally accepted accounting principles (“GAAP”); stock price; price per share of common stock; market share; economic value; financial return ratios, consisting of return on invested capital, return on assets, debt to total capital, return on stockholders’ equity, and return on sales; the ratio of EBIT to capital; the ratio of EBITDA to capital; net income; adjusted net income; operating income; revenues; profit margin; cash flow(s); expense reduction; working capital ratios; achievement of balance sheet or income statement objectives; inventory reductions; inventory turns; successful implementation of strategic initiatives; customer satisfaction measures; and successful integration of acquisitions. Each such goal may be expressed on an absolute or relative basis and may include comparisons based on current internal targets, the past performance of the Company (including the performance of one or more subsidiaries, divisions, or operating units) or the past or current performance of other companies (or a combination of such past and current performance). In the case of earnings-based measures, in addition to the ratios specifically enumerated above, performance goals may include comparisons relating to capital (including, but not limited to, the cost of capital), stockholders’ equity, shares outstanding, assets or net assets, or any combination thereof. With respect to Participants who are not “covered employees” within the meaning of Section 162(m) of the Code and who, in the Committee’s judgment, are not likely to be covered employees at any time during the applicable Performance Period or during any period in which an Award may be paid following a Performance Period, the performance goals established for the Performance Period may consist of any objective or subjective corporate-wide or subsidiary, division, operating unit or individual measures, whether or not listed herein. Performance goals shall be subject to such other special rules and conditions as the Committee may establish at any time within the Applicable Period.

4.2.Impact of Extraordinary Items or Changes in Accounting. The measures utilized in establishing performance goals under the Plan shall, to the extent applicable (i.e., if the relevant performance goal is based on a GAAP measure), be determined in accordance with GAAP and in a manner consistent with the methods used in the Company’s audited consolidated financial statements, without regard to (a) extraordinary or other nonrecurring or unusual items, (b) changes in accounting, as determined by the Company’s independent public accountants in accordance with GAAP, or (c) special charges, such as restructuring or impairment charges, unless, in each case, the Committee decides otherwise within the Applicable Period.

5.1.Performance Goals and Targets. At the time performance goals are established for a Performance Period, the Committee also shall establish an Award opportunity for each Participant or group of Participants, which shall be based on the achievement of one or more specified targets of performance goals. The targets shall be expressed in terms of an objective formula or standard which may be based upon the Participant’s Annual Base Salary or a multiple thereof. In all cases the Committee shall have the sole and absolute discretion to reduce the amount of any payment with respect to any Award that would otherwise be made to any Participant or to decide that no payment shall be made. With respect to each Award, the

Committee may establish terms regarding the circumstances in which a Participant will be entitled to payment notwithstanding the failure to achieve the applicable performance goals or targets (e.g., where the Participant’s employment terminates due to death or disability or where a change in control of the Company occurs).

5.2.Payments. At the time the Committee determines an Award opportunity for a Participant, the Committee shall also establish the payment terms applicable to such Award. Such terms shall include when such payments will be made; provided, however, that the timing of such payments shall in all instances either (A) satisfy the conditions of an exception from Section 409A of the Code (e.g., the short-term deferrals exception described in Treasury Regulation Section 1.409A-1(b)(4)), or (B) comply with Section 409A of the Code and provided, further, that in the absence of such terms regarding the timing of payments, such payments shall occur no later than the 15^th day of the third month of the calendar year following the calendar year in which the Participant’s right to payment ceased being subject to a substantial risk of forfeiture.

6.1.Effective Date. Upon approval by the Board, the Plan shall become effective for Performance Periods beginning on and after January 1, 2018. 

6.2.Amendments and Termination. The Board may amend the Plan as it shall deem advisable, subject to any requirement of stockholder approval required by applicable law, rule or regulation. The Board may terminate the Plan at any time.

6.3.Non-Transferability of Awards. No award under the Plan shall be transferable other than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company. Except to the extent permitted by the foregoing sentence, no award may be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of any such award, such award and all rights there under shall immediately become null and void.

6.4.Tax Withholding. The Company shall have the right to require, prior to the payment of any amount pursuant to an award made hereunder, payment by the Participant of any Federal, state, local or other taxes which may be required to be withheld or paid in connection with such award.

6.5.No Right of Participation or Employment. No person shall have any right to participate in the Plan. Neither the Plan nor any award made hereunder shall confer upon any person any right to continued employment by the Company or any subsidiary or affiliate of the Company or affect in any manner the right of the Company or any subsidiary or affiliate of the Company to terminate the employment of any person at any time without liability hereunder.

6.6.Designation of Beneficiary. If permitted by the Company, a Participant may file with the Committee a written designation of one or more persons as such Participant’s beneficiary or beneficiaries (both primary and contingent) in the event of the Participant’s death. Each beneficiary designation shall become effective only when filed in writing with the Committee during the Participant’s lifetime on a form prescribed by the Committee. The spouse of a married Participant domiciled in a community property jurisdiction shall join in any designation of a beneficiary other than such spouse. The filing with the Committee of a new beneficiary designation shall cancel all previously filed beneficiary designations. If a Participant fails to designate a beneficiary, or if all designated beneficiaries of a Participant predecease the Participant,

then each outstanding award shall be payable to the Participant’s executor, administrator, legal representative or similar person.

6.7.Governing Law. The Plan and each award hereunder, and all determinations made and actions taken pursuant thereto, to the extent not otherwise governed by the Code or the laws of the United States, shall be governed by the laws of the State of Delaware and construed in accordance therewith without giving effect to principles of conflicts of laws.

6.8.Other Plans. Payments pursuant to the Plan shall not be treated as compensation for purposes of any other compensation or benefit plan, program or arrangement of the Company or any of its subsidiaries, unless either (a) such other plan provides that compensation such as payments made pursuant to the Plan are to be considered as compensation there under or (b) the Board or the Committee so determines in writing. Neither the adoption of the Plan nor the submission of the Plan to the Company’s stockholders for their approval shall be construed as limiting the power of the Board or the Committee to adopt such other incentive arrangements as it may otherwise deem appropriate.

6.9.Binding Effect. The Plan shall be binding upon the Company and its successors and assigns and the Participants and their beneficiaries, personal representatives and heirs. If the Company becomes a party to any merger, consolidation or reorganization, then the Plan shall remain in full force and effect as an obligation of the Company or its successors in interest, unless the Plan is amended or terminated pursuant to Section 6.2.

6.10.Unfunded Arrangement. The Plan shall at all times be entirely unfunded and no provision shall at any time be made with respect to segregating assets of the company for payment of any benefit hereunder. No Participant shall have any interest in any particular assets of the Company or any of its affiliates by reason of the right to receive a benefit under the Plan and any such Participant shall have only the rights of an unsecured creditor of the Company with respect to any rights under the Plan.
