(b) You hereby represent and warrant to the Company as follows: (i) You will hold any Shares transferred to you upon the vesting of the Award Units for your own account for investment only and not with a view to, or for resale in connection with, any “distribution” of the Shares within the meaning of the Securities Act. (ii) You understand that the Company may, in its discretion, impose restrictions on the sale, pledge or other transfer of the Shares transferred to you upon the vesting of the Award Units (including the placement of appropriate legends on stock certificates and the issue of stop transfer instructions to the Company’s Transfer Agents) if, in the judgment of the Company, such restrictions are necessary or desirable to comply with the Securities Act, the securities laws of any State or any other law.

If you forfeit any Award Units, then you will also forfeit any related accrued dividend equivalents. Employee Restricted Stock Unit Grant - US

7. Tax Withholding. (a) You hereby agree to make adequate provision for foreign, federal, state and local taxes required by law to be withheld, if any, which arise in connection with the grant, vesting, or settlement, of the Award Units. If you wish to satisfy your tax withholding obligations by delivering proceeds from the sale of Shares that are issued under this Agreement on the market, then you should execute Exhibit A to this Agreement and return it to the Company by the deadline set forth therein. If you have not timely executed Exhibit A to this Agreement, then you shall, immediately upon notification of the amount of withholding taxes due, if any, pay to the Company in cash or by check the amount necessary to satisfy any withholding obligations. The Company (and its Affiliates) shall also have the right to deduct from any compensation or any other payment of any kind due you (including withholding the issuance or delivery of Shares hereunder) the amount of any federal, state, local or foreign taxes required by law to be withheld as a result of the grant, vesting or settlement of the Award Units in whole or in part; provided, however, that the value of the Shares withheld or redeemed may not exceed the maximum statutory rate associated with the transaction to the extent necessary for the Company to avoid an accounting charge.

The Administrator shall make adjustments, in its discretion, to address the treatment of fractional Shares with respect to the Award Units as a result of the stock dividend, stock split or reverse stock split; provided that such adjustments do not result in the issuance of fractional Shares. Adjustments under this Section 8 will be made by the Administrator, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. (b) Non-Change in Control Transactions. Upon any change affecting the Common Stock, the Company or its capitalization, by reason of a spin-off, split-up, dividend, recapitalization, merger, consolidation or share exchange, other than any such change that is part of a transaction resulting in a Change in Control, the Administrator shall make any adjustments with respect to the Award Units as the Administrator determines to be appropriate and equitable. The Administrator’s determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. (c) Unusual or Nonrecurring Events. The Administrator shall make, in its discretion, adjustments in the terms and conditions of, and the criteria included in, Award Units in recognition of unusual or nonrecurring events affecting the Company, or the financial statements of the Company or any Affiliate, or of changes in applicable laws, regulations, or accounting principles, whenever the Administrator determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan; provided that no such adjustment shall be made in contravention of Section 409A of the Code (“Code Section 409A”) with respect to any Award that constitutes a deferred compensation arrangement within the meaning of Code Section 409A. (d) Binding Nature of Agreement. The terms and conditions of this Agreement shall apply with equal force to any additional and/or substitute securities received by you in exchange for, or by virtue of your ownership of, the Award Units, to the same extent as the Award Units with respect to which such additional and/or substitute securities are distributed, whether as a result of any spin-off, stock split-up, Employee Restricted Stock Unit Grant - US

stock dividend, stock distribution, other reclassification of the Common Stock of the Company, or similar event, except as otherwise determined by the Administrator. If the Award Units are converted into or exchanged for, or stockholders of the Company receive by reason of any distribution in total or partial liquidation or pursuant to any merger of the Company or acquisition of its assets, securities of another entity, or other property (including cash), then the rights of the Company under this Agreement shall inure to the benefit of the Company’s successor, and this Agreement shall apply to the securities or other property (including cash) received upon such conversion, exchange or distribution in the same manner and to the same extent as the Award Units. 9. Non-Guarantee of Employment or Service Relationship. Nothing in the Plan or this Agreement shall alter your at-will or other employment status or other service relationship with the Company (or an Affiliate), nor be construed as a contract of employment or service relationship between the Company (or an Affiliate) and you, or as a contractual right of you to continue in the employ of, or in a service relationship with, 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 you at any time with or without cause or notice and whether or not such discharge results in the forfeiture of any Award Units or any other adverse effect on your interests under the Plan. 10. The Company’s Rights. The existence of the Award Units shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or other stocks with preference ahead of or convertible into, or otherwise affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of the Company’s assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise. 11. Notices.

It is the intent of the parties that any such provision(s) of this Agreement declared void, unreasonable, or unenforceable shall be deemed by a court of competent jurisdiction revised to the minimum amount necessary in order to be valid and enforceable. 13. Amendment. This Agreement may be amended from time to time by the Administrator in its discretion; provided, however, that this Agreement may not be modified in a manner that would have a material adverse effect on your rights with respect to the Award Units as determined in the discretion of the Administrator, except as otherwise provided in (a) Section 8 of this Agreement, (b) the Plan or (c) a written document signed by each of the parties hereto. 14. Conformity with Plan. This Agreement is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan.

WITNESS: GRANTEE Date: Employee Restricted Stock Unit Grant - US

Exhibit A Standing Order Election By executing this Irrevocable Standing Order Election (this “Standing Order”), I wish to notify the Company of my election to satisfy any withholding taxes due in connection with each and every vesting date for the Award Units by applying proceeds from a market sale of Company securities issuable as a result of such vesting date. I understand that if I do not execute this Standing Order, then the Company will require that I pay my withholding obligations by cash or check, or the Company will deduct the amount of any withholding obligations from other payments due to me. IMPORTANT NOTES:  You may not enter into this Standing Order if you are in possession of material non-public information. If you are in possession of material non-public information, then you must wait to complete this Standing Order until such time as you no longer possess material non-public information.  No sales may be made pursuant to this Standing Order for 30 calendar days following its execution. To ensure that you can satisfy your withholding obligations by selling Shares in the market, you should return this form to the Company as soon as possible, but in no event later than 30 days before the first vesting date of your Award Units listed in the Agreement. By signing below, I understand that I am agreeing to the following provisions: 1. I am executing this Standing Order to authorize the Company and any broker the Company designates (the “Broker”) to take the actions described in this Paragraph 1. I authorize the Company to transfer the Shares issued to me upon settlement of the Award Units to the Broker to be held in an account for my benefit (the “Brokerage Account”), and I irrevocably authorize the Broker to sell, at the market price and on the date the Shares are issued by the Company (or, if all or a portion of the sale cannot be completed on such date because of insufficient demand or a market disruption, then on the next following business day on which the sale can be made) the number of Shares necessary to obtain proceeds sufficient to satisfy the amount of any withholding obligations associated with my Award Units indicated by the Company to the Broker. I understand and agree that the number of Shares that the Broker will sell will be based on the Company’s estimate (or Broker’s estimate if it provides such service) of the Shares required to satisfy the withholding obligations, using the closing price of a Share of the Company’s common stock on the trading day immediately prior to vesting date (or such other date as any withholding obligations become due). I agree to execute and deliver such documents, instruments and certificates as may reasonably be required in connection with the sale of the Shares pursuant to this Standing Order. 2. I agree that the proceeds received from the sale of Shares pursuant to Paragraph 1 will be used to satisfy any withholding obligations associated with my Award Units and, accordingly, I hereby authorize the Broker to pay such proceeds to the Company for such purpose. I understand that, to the extent that the proceeds obtained by such sale exceed the amount necessary to satisfy the withholding obligations, such excess proceeds shall be deposited into the Brokerage Account and, if a shortfall occurs, the Broker may sell additional Shares held in my Brokerage Account, the Company may deduct any remaining withholding obligations from any compensation or other payment of any kind due to me, or the Company may require that I pay any remaining withholding obligations to by cash or check. I further understand that any Shares that are issuable to me as a result of the vesting of my Award Units that are not sold to satisfy withholding obligations will be deposited into the Brokerage Account.
