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.

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

(a)    to designate the Participants for a Performance Period;

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.

The Committee shall establish for each Performance Period one or more performance goals for each Participant or for any group of Participants (or both). Performance goals may be based on one or more corporate-wide or subsidiary, division, operating unit or individual measures, including without limitation any of the following: the attainment by a share of Common Stock of a specified Fair Market Value for a specified period of time; increase in stockholder value; earnings per share; return on or net assets; return on equity; return on investments; return on capital or invested capital; total stockholder return; earnings or income of

the Company before or after taxes and/or interest; earnings before interest, taxes, depreciation and amortization (“EBITDA”); EBITDA margin; operating income; revenues; operating expenses, attainment of expense levels or cost reduction goals; market share; cash flow, cash flow per share, cash flow margin or free cash flow; interest expense; economic value created; gross profit or margin; operating profit or margin; net cash provided by operations; price-to-earnings growth; and strategic business criteria, consisting of one or more objectives based on meeting specified goals relating to market penetration, customer acquisition, business expansion, cost targets, customer satisfaction, reductions in errors and omissions, reductions in lost business, management of employment practices and employee benefits, supervision of litigation, supervision of information technology, quality and quality audit scores, efficiency, and acquisitions or divestitures; any combination of the foregoing, or any other objective or subjective corporate-wide or subsidiary, division, operating unit or individual measures, whether or not listed herein. 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 one or more other companies or market indices (or a combination of such past and current performance). 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), shareholders’ equity, shares outstanding, assets or net assets, sales or any combination thereof. The applicable performance measures may be applied on a pre- or post-tax basis and may be adjusted to include or exclude any identified components of any performance measure, including, without limitation, foreign exchange gains and losses, asset writedowns, acquisitions and divestitures, change in fiscal year, unbudgeted capital expenditures, special charges such as restructuring or impairment charges, debt refinancing costs, extraordinary or noncash items, unusual, infrequently occurring, nonrecurring, one-time or other unusual or unanticipated events affecting the Company or its financial statements or changes in law or accounting principles (“Adjustment Events”). In the sole discretion of the Committee, the Committee may amend or adjust the performance measures or other terms and conditions of an outstanding award in recognition of any Adjustment Events. Performance goals shall be subject to such other special rules and conditions as the Committee may establish at any time.

4.Performance Goals and Targets. At the time one or more 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 such specified performance goals. The amount payable to a Participant upon achievement of the applicable performance goals may be expressed in terms of a formula or standard, including a fixed cash amount, the allocation of a bonus pool or a percentage of the Participant’s base salary. The Committee reserves the discretion to increase or decrease the amount of any payment with respect to any Award that would otherwise be made to any Participant pursuant to the performance goals established in accordance with Article IV, and may exercise such discretion based on the extent to which any other performance goals are achieved, regardless of whether such performance goals are set forth in this Plan or are assessed on an objective or subjective basis. 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.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.Effective Date. The Plan became effective as of the date the Plan was approved by the Board.

7.Amendments and Termination. The Board may amend the Plan as it shall deem advisable; provided, however, that no amendment may materially impair the rights of a Participant with respect to an outstanding Performance Period. The Board may terminate the Plan at any time.

8.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 thereunder shall immediately become null and void.

9.Tax Withholding. The Company shall have the right to withhold from the payment of any award hereunder or require, prior to the payment of any award 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.

10.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.

11.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.

12.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 thereunder or (b) the Board or the Committee so determines in writing. The adoption of the Plan shall not be construed as limiting the power of the Board or the Committee to adopt such other incentive arrangements as it may otherwise deem appropriate.

13.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.

14.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.

15.Awards Subject to Clawback. The Awards granted under this Plan and any cash payment delivered pursuant to an Award are subject to forfeiture, recovery by the Company or other action pursuant to the terms of the applicable Award or any clawback or recoupment policy which the Company may adopt from time to time, including without limitation any such policy which the Company may be required to adopt under the Dodd-Frank Wall Street Reform and Consumer Protection Act and implementing rules and regulations thereunder, or as otherwise required by law.
