general assets of the Company. No provision of the Plan shall require the Company, for the purpose of satisfying any obligations under the Plan, to purchase assets or place any assets in a trust or other entity to which contributions are made or
otherwise to segregate any assets, nor shall the Company maintain separate bank accounts, books, records or other evidence of the existence of a segregated or separately maintained or administered fund for such purposes. Participants shall have no
rights under the Plan other than as unsecured general creditors of the Company. 
 4.2 Timing of Payment. Payment of each
Actual Award shall be made as soon as administratively practicable as determined by the Administrator after the end of the Performance Period during which the Actual Award was earned, but in no event later than (a) the 15th day of the third
month following the end of the Company’s taxable year in which the Performance Period has ended, or (b) March 15th of the calendar year following the calendar year in which the applicable Performance Period has ended. Notwithstanding

 4.4 Repayment and Forfeiture of Actual Awards. Notwithstanding anything in this Plan
or any participation agreement to the contrary, if the Administrator determines that the Employee engaged in an act of embezzlement, fraud or breach of a fiduciary duty during the Employee’s employment that contributed to an obligation to
restate the Company’s financial statements (“Contributing Misconduct”), the Employee shall be required to repay to the Company, in cash and upon demand, the Excess Proceeds (as defined below) if the Actual Award was paid at any time
during the twelve-month period following the first public issuance or filing with the SEC of the financial statements required to be restated. The term “Excess Proceeds” means, with respect to any Actual Award, an amount determined
appropriate by the Administrator to reflect the effect of the restatement on the applicable performance criteria used under the Plan in the applicable Performance Period. The return of the Excess Proceeds is in addition to and separate from any
other relief available to the Company due to the Employee’s Contributing Misconduct. Any determination by the Administrator with respect to the foregoing shall be final, conclusive and binding on all interested parties.  
 SECTION 5

 5.1 Administrator Authority. It shall be the duty of the Administrator to administer
the Plan in accordance with the Plan’s provisions. The Administrator shall have all powers and discretion necessary or appropriate to administer the Plan and to control its operation, including, but not limited to, the power to

include the individuals delegated such authority. 
 5.4 Indemnification of Administrator. The Company shall indemnify
and hold harmless members of the Administrator, or any officer or employee of the Company delegated authority with respect to the administration of the Plan, for any expense, liability, or loss, including attorneys’ fees, judgments, fines,
penalties, amounts paid or to be paid in settlement, any interest, assessments, or other charges imposed thereon, any federal, state, local, or foreign taxes, and all other costs and obligations, paid or incurred in connection with any action,

from any distributions under the Plan any amount required to satisfy the Company’s income, employment and other tax withholding obligations under applicable law. Each Participant, as a condition to participating in the Plan, agrees to make
appropriate arrangements with the Company (or the Affiliate employing or retaining the Participant) for the satisfaction of all Federal, state, local and foreign income, employment and other tax withholding requirements applicable to any Actual
Award payable hereunder. 
 6.2 No Effect on Employment or Service. Nothing in the Plan shall interfere with or limit in
any way the right of the Company to terminate any Participant’s employment or service at any time, with or without cause. For purposes of the Plan, transfer of employment of a Participant between the Company and any one of its Affiliates (or
between Affiliates) shall not be deemed a Termination of Service. Employment with the Company and its Affiliates is on an at-will basis only. The Company expressly reserves the right, which may be exercised at any time and without regard to when
during a Performance Period such exercise occurs, to terminate any individual’s employment with or without cause, and to treat him or her without regard to the effect that such treatment might have upon him or her as a Participant. 

6.3 Participation. No Employee shall have the right to be selected to receive an award under this Plan, or, having been so
selected, to be selected to receive a future award. 
 6.4 Successors. All obligations of the Company under the Plan,
with respect to awards granted hereunder, shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of
the business or assets of the Company.

transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will, by the laws of descent and distribution, or to the limited extent provided in Section 6.5. All rights with respect to an award granted to a Participant
shall be available during his or her lifetime only to the Participant.

intended that the Plan shall be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), pursuant to the requirement that all payments hereunder shall be paid within the applicable short-term
deferral period as set forth in Section 1.409A-1(b)(4) of the final regulations issued under Section 409A. The Administrator shall administer and interpret the Plan in a manner consistent with this short-term deferral exception and any
