Annex A: Restricted Stock Unit Award Agreement

It is understood and agreed that the Award of RSUs evidenced by the Award Notice to which this is annexed is subject to the following additional terms and conditions.

1.Grant of RSUs. On the Grant Date, the Participant was awarded the number of RSUs set forth in the Award Notice.

2.Vesting of RSUs. The RSUs shall become vested and nonforfeitable in accordance with the Vesting Schedule set forth in the Award Notice. Except as otherwise provided in this Section 2, if the Participant ceases to be an employee of the Company or an Affiliate, whether initiated by the Participant or the Company and for any reason, all rights to the RSUs that have not vested prior to the date of the Participant’s termination of employment shall terminate immediately and be forfeited in their entirety without compensation to the Participant, and the forfeited RSUs shall be cancelled.

(a)Death or Disability. In the event of the Participant’s death or Disability, a pro rata portion of the total RSUs shall become immediately vested as of the date of such death or Disability based on the ratio of the number of full months of employment completed during the Vesting Schedule to the date of the Participant’s death or Disability divided by the total number of months in the Vesting Schedule reduced by the number of shares that have already vested.

(b)Termination of Service Due to Retirement. If the Participant terminates employment due to Retirement, then if the effective date of such Retirement is (i) during the first year of the Vesting Schedule, all of the Participant’s rights to the RSUs shall terminate immediately and be forfeited in their entirety, without compensation to the Participant, and the forfeited RSUs shall be cancelled, (ii) during the second year of the Vesting Schedule, a pro rata portion of the total RSUs shall become immediately vested as of the date of the Participant’s termination of employment, based on the ratio of the number of full months of employment completed during the Vesting Schedule to the date of the Participant’s termination of employment divided by the total number of months in the Vesting Schedule reduced by the number of shares that have already vested, and (iii) during the third year of the Vesting Schedule, the Participant’s RSUs shall become immediately fully vested as of the date of the Participant’s termination of employment.

(c)Qualifying Termination. If the Participant experiences a Qualifying Termination, any Replacement Award granted in respect of the RSUs shall vest in full immediately upon the date of such termination of employment.

3.Settlement of RSUs. Subject to Section 9, vested RSUs shall be settled by the issuance of Shares as soon as reasonably practicable (and in no event later than sixty days)

following the earliest to occur of (a) the originally scheduled Vesting Date, (b) the Participant’s death, (c) the Participant’s Disability, and (d) the Participant’s Separation from Service for any reason within two years following a Change in Control (provided that to the extent necessary to avoid the application of a penalty under Section 409A, this clause (d) shall only apply if the applicable Change in Control constitutes a “change in ownership or effective control of” the Company or a “change in the ownership of a substantial portion of the assets of” the Company as determined under Treasury Regulation Section 1.409A-3(i)(5)).

4.Retention of Shares. Executives are required to own Shares at designated multiples of their base salary. If the Participant has not achieved an applicable stock ownership requirement, the Company may require the Participant to hold additional net after-tax Shares received under this Award until the requirement is met.

5.Voting Rights. Since RSUs do not represent actual Shares, no voting rights or other rights as a stockholder of the Company arise with respect to the RSUs until Shares have been delivered to the Participant upon settlement of the RSUs.

6.Tax Withholding. Pursuant to Article 14 of the Plan, the Committee has the power and the right to deduct or withhold, or require the Participant to remit to the Company, an amount sufficient to satisfy any federal, state, and local taxes (including the Participant’s FICA obligations) required by law to be withheld with respect to the Award. The Committee may condition the delivery of vested Shares upon the Participant’s satisfaction of such withholding obligations. The withholding requirement for Shares will be satisfied by the Company withholding Shares having a fair market value equal to federal income tax withholding obligations using an IRS accepted methodology plus additional amounts for state and local tax purposes, as applicable, including payroll taxes, that are applicable to such supplemental taxable income but with rates not to exceed the maximum effective statutory rates, unless the Participant elects, in a manner satisfactory to the Committee, to remit an amount to satisfy the withholding requirement subject to such restrictions or limitations that the Committee, in its sole discretion, deems appropriate. Such election must be made before, and is irrevocable after, December 15 of the last year in the Vesting Schedule, and cannot be made or revoked while the Participant possesses information that will be material nonpublic information at the time the Shares are issued such that the Participant would be prohibited from trading on the Company’s stock under its Insider Trading Policy.

7.Non-Guarantee of Employment Relationship or Future Awards. Nothing in the Plan, the Award Notice, or this Award Agreement will alter the Participant’s at-will or other employment status with the Company or an Affiliate, nor be construed as a contract of employment between the Participant and the Company or an Affiliate, or as a contractual right for the Participant to continue in the employ of the Company or an Affiliate for any period of time, or as a limitation of the right of the Company or an Affiliate to discharge the Participant at any time with or without cause or notice and whether or not

such discharge results in the forfeiture of any of the Participant’s RSUs, or as a right to any future Awards.

8.Non-transferability of RSUs. No RSUs granted under the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution.

9.Section 409A. This Award Agreement and the RSUs granted hereunder are intended to comply with the requirements of Section 409A or an exemption or exclusion therefrom, and, with respect to RSUs that are subject to Section 409A, the Plan and this Award Agreement shall be interpreted and administered in all respects in accordance with Section 409A (including with respect to the application of any defined terms to RSUs that constitute nonqualified deferred compensation, which defined terms shall be interpreted to have the meaning required by Section 409A to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A). Each payment (including the delivery of Shares) under the RSUs that constitutes nonqualified deferred compensation subject to Section 409A shall be treated as a separate payment for purposes of Section 409A. In no event may the Participant, directly or indirectly, designate the calendar year of any payment to be made under this Award Agreement that constitutes nonqualified deferred compensation subject to Section 409A. Notwithstanding any other provision of this Award Agreement to the contrary, if the Participant is a “Specified Employee” within the meaning of Section 409A of the Code (as determined in accordance with the methodology established by the Company as in effect on the date of the Participant’s separation from service within the meaning of Section 409A (“Separation from Service”)), amounts that constitute nonqualified deferred compensation within the meaning of Section 409A that would otherwise be payable by reason of the Participant’s Separation from Service during the six-month period immediately following such Separation from Service shall instead be paid or provided on the first business day following the date that is six months following the Participant’s Separation from Service.

10.Personal Information. The Participant agrees that the Company and its suppliers or vendors may collect, use, and disclose the Participant’s personal information for the purposes of the implementation, management, administration, and termination of the Plan.

11.Amendment. The Committee may amend, alter, modify, suspend, or terminate the Award Notice or this Award Agreement at any time and from time to time, in whole or in part; provided, however, no amendment, alteration, modification, suspension, or termination of the Award Notice or Award Agreement shall adversely affect in any material way the Award Notice or this Award Agreement, without the Participant’s written consent, except to the extent such amendment, alteration, modification, suspension, or termination is reasonably determined by the Committee in its sole discretion to be necessary to comply with applicable laws, rules, regulations, or is

necessary for such approvals by any governmental agencies or national securities exchanges as may be required.

12.Binding Effect.

The Participant has carefully read and considered the provisions of this Section 21 and, having done so, agrees that the restrictions set forth herein are fair and reasonable and are reasonably required for the protection of the legitimate business interests of the Company. The Participant further agrees and acknowledges that the provisions of this Section 21 are reasonable with respect to duration, geographic area, and scope considering the Participant’s access to the Company's customer relationships and other relevant factors, and agrees that the Company's need for the protection afforded herein is greater than any hardship the Participant might experience by complying with the terms set forth herein. If a final judicial determination is made by a court of competent jurisdiction that the time, territory, scope or other restrictions contained in this Section 21 of this Award Agreement is an unreasonable or otherwise unenforceable restriction against the Participant, neither this Award Agreement nor the provisions of this Section 21 shall be rendered void, but shall be deemed amended to apply as to such maximum time, territory, scope and to such other extent as such court may judicially determine or indicate to be reasonable or, if such court does not so determine or indicate, to the maximum extent which any pertinent statute or judicial decision may indicate to be a reasonable restriction under the circumstances involved.

(j)Survival. The parties' rights and obligations under this Section 21 survive the termination of the Participant’s employment with the Employer Group.
