such proposed transferee; provided that such RSUs shall remain subject to this Agreement (including without limitation the terms of Forfeiture and the restrictions on transfer set forth in this Section 3 and such permitted transferee

 5. Section 409A. To the extent Participant is or becomes subject to U.S. Federal
income taxation, the RSUs and payments made pursuant to this Agreement are intended to comply with or qualify for an exemption from the requirements of Section 409A and this agreement shall be construed consistently therewith. Neither the
Company nor the Participant shall have any right to accelerate or defer payment under this Agreement except to the extent specifically permitted or required by Section 409A. Terms defined in the Agreement shall have the meanings given such
terms under Section 409A if and to the extent required to comply with Section 409A. Notwithstanding any other provision of this Agreement, the Company reserves the right, to the extent it deems necessary or advisable, in its sole
discretion, to unilaterally amend the Plan and/or this Agreement to ensure that all awards hereunder qualify for exemption from or otherwise comply with Section 409A; provided, however, that the Company makes no undertaking to preclude
Section 409A from applying to this Award or to guarantee compliance therewith. Any payments described in this Section 5 that are due within the “short term deferral period” as defined in Section 409A shall not be treated as
deferred compensation unless applicable law requires otherwise. Notwithstanding the foregoing, the Company, its affiliates, directors, officers and agents shall have no liability to a Participant, or any other party, if the RSU that is intended to
be exempt from, or compliant with, Section 409A is not so exempt or compliant, or for any action taken by the Company’s Board of Directors, a committee thereof or its delegates. 

6. Taxes. 
 (a) The
Company’s obligation to deliver Shares to the Participant upon the vesting of the RSUs shall be subject to the satisfaction of all income tax (including federal, state and local taxes) and any other tax related requirements (“Taxes”).

 (b) The Participant has reviewed with the Participant’s own tax advisors the federal, state, local and foreign tax consequences of
this equity award and the transactions contemplated by this Agreement. The Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The Participant understands that the
Participant (and not the Company) shall be responsible for the Participant’s own tax liability that may arise as a result of this equity award or the transactions contemplated by this Agreement. 

7. Nature of the Grant. In signing this Agreement, the Participant acknowledges that: 

(a) The Plan is established voluntarily by the Company, it is discretionary in nature and may be modified, amended, suspended or terminated by
the Company at any time, except to the extent otherwise provided in the Plan and this Agreement. 
 (b) The grant of RSUs is voluntary and
occasional and does not create any contractual or other right to receive future awards of RSUs, or benefits in lieu of RSUs even if RSUs have been awarded repeatedly in the past; 

(c) All decisions with respect to future grants of RSUs, if any, will be at the sole discretion of the Company; 

  
 3 

 (d) The Participant’s participation in the Plan is voluntary. 

(e) RSUs are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculation of any wage

the Company. 
 (f) No voting or dividend or distribution rights apply with respect to the RSUs. 

(g) The future value of the underlying Shares is unknown and cannot be predicted with certainty. 

(h) If the Participant receives Shares upon vesting, the value of such Shares acquired on vesting of RSUs may increase or decrease in value.

 (i) In consideration of the grant of RSUs, no claim or entitlement to compensation or damages arises from termination of the RSUs or
diminution in value of the RSUs or Shares received upon vesting of RSUs resulting from termination of the Participant’s service relationship by the Company (for any reason whatsoever and whether or not in breach of local labor laws) and the
Participant irrevocably releases the Company from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by signing this Agreement, the Participant shall
be deemed irrevocably to have waived his or her entitlement to pursue such claim. 
 (j) If the Participant ceases to provide services, the
Participant’s right to receive RSUs and vest under the Plan, if any, will terminate effective as of the date that the Participant is no longer actively providing services to the Company and will not be extended by any notice period mandated
under local law; the Committee shall have the exclusive discretion to determine when the Participant is no longer actively providing services to the company for purposes of the Plan. 

8. Data Privacy Notice and Consent. The Participant hereby explicitly and unambiguously consents to the collection, use and transfer,
in electronic or other form, of his or her personal data as described in this paragraph, by and among, as applicable, the Company and its subsidiaries and affiliates for, among other purposes, implementing, administering and managing the

plan service provider or other third parties assisting the Company with processing of Data. The Participant understands that these recipients may be located in the United States, and that the recipient’s country may have different data privacy
laws and protections than in the Participant’s country. The Participant authorizes them to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes described in this section, including any requisite
transfer to Broker or such other stock plan service provider or other third party as may be required for the administration of the Plan and/or the subsequent holding of Shares of stock on the Participant’s behalf. The Participant understands
that he or she may, at any time, request access to the Data, request any necessary amendments to it or refuse or withdraw the consents herein, in any case without cost, by contacting the Company’s Vice President of Human Resources in writing.

 (vi) “Retirement” means a voluntary termination

Company. The Company may waive such advance notice requirement in its sole discretion. 
 (vii) “Vesting Date” is defined on

 (b) Vesting Period. Subject to the terms and conditions of this Agreement (including the
Forfeiture provisions described in Section 2 below), the RSUs shall vest according to the terms set forth in Exhibit A. As soon as practicable after each applicable Vesting Date, but no later than thirty (30) days following the

A, if applicable) of the Participant’s unforfeited RSUs shall become immediately 
  

	1 	Only certain of the Company’s officers and other employees designated by the Compensation Committee of the Board of Directors will be entitled to acceleration of vesting upon Retirement. 

	2 	 Only certain of the Company’s officers and other employees designated by the Compensation Committee of the Board of Directors will be entitled to

any of the following events: (I) any “person” (as that term is used in Section 13 and 14(d)(2) of the Securities Exchange Act of 1934 (“Exchange Act”)) becomes the beneficial owner (as that term is used in
Section 13(d) of the Exchange Act), directly or indirectly, of fifty percent (50%) or more of the Company’s capital stock entitled to vote in the election of directors; (II) the shareholders of the Company approve any consolidation or
merger of the Company, other than a consolidation or merger of the Company in which the holders of the common stock of the Company immediately prior to the consolidation or merger hold more than fifty percent (50%) of the common stock of the
surviving corporation immediately after the consolidation or merger; or (III) the shareholders of the Company approve the sale or transfer of all or substantially all of the assets of the Company to parties that are not within a “controlled

than a reduction which is part of a general salary reduction program affecting senior executives of the Company), (III) a material reduction in the aggregate value of the pension and welfare benefits provided to the Participant from those in effect
prior to the Change in Control (other than a reduction which is proportionate to the reductions applicable to other senior executives pursuant to a cost-saving plan that includes all senior executives), (IV) a material breach of any provision of the
Participant’s Employment Agreement by the Company or (V) the Company’s requiring the Participant to be based at a location that creates for the Participant a one way commute in excess of 60 miles from his primary residence, except for

treated as a termination for Good Reason (I) if the Participant shall have consented in writing to the occurrence of the event giving rise to the claim of termination for Good Reason or (II) unless the Participant shall have delivered a written
notice to the Company within thirty (30) days of his having actual knowledge of the occurrence of one of such events stating that he intends to terminate his employment for Good Reason and specifying the factual basis for such termination, and

the Vesting Date (or, if later, on the Determination Date) an “executive officer” of the Company (as defined in Rule 3b-7 under the Exchange Act) and (ii) the RSUs are (or were at any time) subject to performance criteria per
Exhibit A, then the RSUs (and any Shares issued under the RSUs) shall be subject to potential cancellation, recoupment, rescission, payback or other action in accordance with the terms of any applicable Company clawback policy (the
“Clawback Policy”) or any applicable law, as may be in effect from time to time. The Participant hereby acknowledges and consents to the Company’s application, implementation and enforcement of (i) any applicable Clawback Policy
as may be in effect from time to time and (ii) any provision of applicable law relating to cancellation, recoupment, rescission or payment of compensation, and agrees that the Company may take such actions as may be necessary to effectuate the
Clawback Policy without further consideration or action.

 3. Restrictions on Transfer. The Participant shall not sell, assign, transfer, pledge,
hypothecate or otherwise dispose of, by operation of law or otherwise (collectively “transfer”) any RSUs, or any interest therein; provided that the Participant may transfer the RSUs to the extent necessary to fulfill a domestic relations
order (as defined in Section 414(p)(1)(B) of the Code). 
 4. Provisions of the Plan. This Agreement is subject to the
provisions of the Plan, a copy of which is furnished to the Participant with this Agreement. 
 5. Section 409A. To the extent
the Participant is or becomes subject to U.S. Federal income taxation, the RSUs and payments made pursuant to this Agreement are intended to comply with or qualify for an exemption from the requirements of Section 409A and this Agreement shall
be construed consistently therewith. Neither the Company nor the Participant shall have any right to accelerate or defer payment under this Agreement except to the extent specifically permitted or required by Section 409A. Terms defined in the
Agreement shall have the meanings given such terms under Section 409A if and to the extent required to comply with Section 409A, including that references to “termination of employment” shall be considered to be references to a
“separation from service” as defined under Section 409A. Notwithstanding any other provision of this Agreement, the Company reserves the right, to the extent it deems necessary or advisable, in its sole discretion, to unilaterally
amend the Plan and/or this Agreement to ensure that all awards hereunder qualify for exemption from or otherwise comply with Section 409A; provided, however, that the Company makes no undertaking to preclude Section 409A from applying to
this Award or to guarantee compliance therewith. Any payments described in this Section 5 that are due within the “short term deferral period” as defined in Section 409A shall not be treated as deferred compensation unless
applicable law requires otherwise. If and to the extent any portion of any payment, compensation or other benefit provided to the Participant in connection with his or her employment termination is determined to constitute “nonqualified
deferred compensation” within the meaning of Section 409A and the Participant is a specified employee as defined in Section 409A(2)(B)(i) of the Code, as determined by the Company in accordance with its procedures, by which
determination the Participant hereby agrees that he or she is bound, such portion of the payment, compensation or other benefit shall not be paid before the day that is six months plus one day after the date of separation from service (as determined
under Section 409A (the “New Payment Date”)), except as Section 409A may then permit. The aggregate of any payments that otherwise would have been paid to the Participant during the period between the date of separation from
service and the New Payment Date shall be paid to the Participant in a lump sum on the New Payment Date, and any remaining payments will be paid on their original schedule. Notwithstanding the foregoing, the Company, its affiliates, directors,
officers and agents shall have no liability to a Participant, or any other party, if the RSU that is intended to be exempt from, or compliant with, Section 409A is not so exempt or compliant, or for any action taken by the Company’s Board
of Directors, a committee thereof or its delegates.

 6. Withholding Taxes. 

(a) The Company’s obligation to deliver Shares to the Participant upon the vesting of RSUs shall be subject to the satisfaction of all
income tax (including federal, state and local taxes), social insurance, payroll tax, payment on account or other tax related withholding requirements (“Withholding Taxes”). In order to satisfy all Withholding Taxes of the
Participant’s RSUs, the Participant agrees to the following: 
 (b) The Participant hereby elects to satisfy all Withholding Taxes
obligation that may arise through the retention by the Company of Shares. Accordingly, the Participant hereby instructs the Company, with no further action by the Participant, to deduct and retain from the number of Shares to which the Participant
is entitled from the RSUs then vested or scheduled to vest such number of Shares as is equal to the value of the Withholding Taxes. The fair market value of such surrendered Shares will be based on the closing price of the Company’s Common
Stock on the trading day preceding the date such Withholding Tax obligation is satisfied. 
 (c) Participant has reviewed with the
Participant’s own tax advisors the federal, state, local and foreign tax consequences of this equity award and the transactions contemplated by this Agreement. The Participant is relying solely on such advisors and not on any statements or
representations of the Company or any of its agents. The Participant understands that the Participant (and not the Company) shall be responsible for the Participant’s own tax liability that may arise as a result of this equity award or the
transactions contemplated by this Agreement. 
 (d) The Participant represents to the Company that, as of the date hereof, he/she is not
aware of any material nonpublic information about the Company or the Common Stock. The Participant and the Company have structured this Agreement to constitute a “binding contract” relating to the retention by the Company of Common Stock
pursuant to this Section 6, consistent with the affirmative defense to liability under Section 10(b) of the Securities Exchange Act of 1934 under Rule 10b5-1(c) promulgated under such Act. 

7. Nature of the Grant. In signing this Agreement, the Participant acknowledges that: 

(a) The Plan is established voluntarily by the Company, it is discretionary in nature and may be modified, amended, suspended or terminated by
the Company at any time, except to the extent otherwise provided in the Plan and this Agreement. 
 (b) The grant of RSUs is voluntary and
occasional and does not create any contractual or other right to receive future awards of RSUs, or benefits in lieu of RSUs even if RSUs have been awarded repeatedly in the past. 

(c) All decisions with respect to future grants of RSUs, if any, will be at the sole discretion of the Company. 

(d) The Participant’s participation in the Plan is voluntary. 

(e) RSUs are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculation of any wage
payment, severance, redundancy, or other end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for
the Company or the Participant’s employer or arising under any employment agreement. 

  
 5 

 (f) No voting or dividend or distribution rights apply with respect to the RSUs. 

(g) The future value of the underlying Shares is unknown and cannot be predicted with certainty. 

(h) If the Participant receives Shares upon vesting, the value of such Shares acquired on vesting of RSUs may increase or decrease in value.

 (i) In consideration of the grant of RSUs, no claim or entitlement to compensation or damages arises from termination of the RSUs or
diminution in value of the RSUs or Shares received upon vesting of RSUs resulting from termination of the Participant’s employment by the Company or the Participant’s employer (for any reason whatsoever and whether or not in breach of
local labor laws) and the Participant irrevocably releases the Company and his or her employer from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then,
by signing this Agreement, the Participant shall be deemed irrevocably to have waived his or her entitlement to pursue such claim. 
 (j) If
the Participant ceases to be an employee (whether or not in breach of local labor laws), the Participant’s right to receive RSUs and vest under the Plan, if any, will terminate effective as of the date that the Participant is no longer actively
employed by the Company and will not be extended by any notice period mandated under local law (e.g., active employment would not include a period of “garden leave” or similar period pursuant to local law); the Committee shall have
the exclusive discretion to determine when the Participant is no longer actively employed for purposes of the Plan. 
 8. Data Privacy
Notice and Consent. The Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of his or her personal data as described in this paragraph, by and among, as applicable, the
Participant’s employer and the Company and its subsidiaries and affiliates for, among other purposes, implementing, administering and managing the Participant’s participation in the Plan. The Participant understands that the Company and
its subsidiaries hold certain personal information about the Participant, including the Participant’s name, home address and telephone number, date of birth, social security number or identification number, salary, nationality, job title, any
Shares or directorships held in the Company, details of all options or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in the Participant’s favor, for the purpose of managing and administering the
Plan (“Data”). The Participant further understands that the Company and/or its subsidiaries will transfer Data amongst themselves as necessary for employment purposes, including implementation, administration and management of the
Participant’s participation in the Plan, and that the Company and/or any of its subsidiaries may each further transfer Data to Broker or such other stock plan service provider or other third parties assisting the Company with processing of
Data. The Participant understands that these recipients may be located in the United States, and that the recipient’s country may have different data privacy laws and protections than in the Participant’s country. The Participant
authorizes them to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes described in this section, including any requisite transfer to Broker or such other stock plan service provider or

  
 6 

 
other third party as may be required for the administration of the Plan and/or the subsequent holding of Shares of stock on the Participant’s behalf. The Participant understands that he or
she may, at any time, request access to the Data, request any necessary amendments to it or refuse or withdraw the consents herein, in any case without cost, by contacting in writing his or her local human resources representative. The Participant
understands, however, that withdrawal of consent may affect the Participant’s ability to participate in or realize benefits from the Plan. For more information on the consequences of refusal to consent or withdrawal of consent, the Participant
understands that he or she may contact his or her local human resources representative. 
 9. Miscellaneous. 

(a) No Rights to Employment. The Participant acknowledges and agrees that the vesting of the RSUs pursuant to Section 1 and
Exhibit A hereof is earned only in accordance with the terms of such sections. The Participant further acknowledges and agrees that the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express
or implied promise of continued engagement as an employee for the vesting period, for any other period, or at all. 
 (b)
Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, and each other provision of this Agreement shall be severable and

may be waived, either generally or in any particular instance, by the Board of Directors of the Company or its delegate.

respective signature to this Agreement, or at such other address or addresses as either party shall designate to the other in accordance with this Section 9(e). 

(f) Pronouns. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine

 (h) Electronic Delivery. The Company may, in its sole discretion, decide to deliver any
documents related to participation in the Plan, RSUs granted under the Plan or future RSUs that may be granted under the Plan by electronic means or to request the Participant’s consent to participate in the Plan by electronic means. The
Participant hereby consents to receive such documents by electronic delivery and, if requested, to agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated
