      harmless by the Company against and from any loss, cost, liability, or expense (including attorneys’ fees) that may be imposed upon or incurred by such Indemnifiable Person in connection with or resulting from any action, suit or proceeding to which
      such Indemnifiable Person may be a party or in which such Indemnifiable Person may be involved by reason of any action taken or omitted to be taken or determination made with respect to the Plan or any Award hereunder and against and from any and all
      amounts paid by such Indemnifiable Person with the Company’s approval, in settlement thereof, or paid by such Indemnifiable Person in satisfaction of any judgment in any such action, suit or proceeding against such Indemnifiable Person, and the
      Company shall advance to such Indemnifiable Person any such expenses promptly upon written request (which request shall include an undertaking by the Indemnifiable Person to repay the amount of such advance if it shall ultimately be determined, as
      provided below, that the Indemnifiable Person is not entitled to be indemnified); provided, that the Company shall have the right, at its own expense, to assume and defend any such action, suit or proceeding and once the Company gives notice
      of its intent to assume the defense, the Company shall have sole control over such defense with counsel of the Company’s choice. The foregoing right of indemnification shall not be available to an Indemnifiable Person to the extent that a final
      judgment or other final adjudication (in either case not subject to further appeal) binding upon such Indemnifiable Person determines that the acts, omissions or determinations of such Indemnifiable Person giving rise to the indemnification claim
      resulted from such Indemnifiable Person’s fraud or willful criminal act or omission or that such right of indemnification is otherwise prohibited by law or by the organizational documents of any member of the Company Group. The foregoing right of
      indemnification shall not be exclusive of or otherwise supersede any other rights of indemnification to which such Indemnifiable Persons may be entitled under the organizational documents of any member of the Company Group, as a matter of law, under
      an individual indemnification agreement or contract or otherwise, or any other power that the Company may have to indemnify such Indemnifiable Persons or hold such Indemnifiable Persons harmless.

      fees paid to such Non-Employee Director during the fiscal year, shall not exceed $500,000 in total value (calculating the value of any such Awards based on the grant date fair value of such Awards for financial reporting purposes).

   

  (d)       Share Counting. Other than with respect to Substitute Awards, to the extent that an Award expires or is canceled, forfeited, or terminated without issuance to the Participant
      of the full number of shares of Common Stock to which the Award related, the unissued shares will returned for future grant under the Plan. Shares of Common Stock shall be deemed to have been issued in settlement of Awards if the Fair Market Value
      equivalent of such shares is paid in cash; provided, however, that no shares shall be deemed to have been issued in settlement of a SAR, Other Equity-Based Award or Restricted Stock Unit that only provides for settlement in cash and
      settles only in cash. Shares withheld in payment of the Exercise Price or taxes relating to an Award and shares equal to the number of shares surrendered in payment of any Exercise Price or taxes relating to an Award shall constitute shares issued to
      the Participant and shall reduce the Plan Share Reserve.

   

  (e)       Source of Shares. Shares of Common Stock issued by the Company in settlement of Awards may be authorized and unissued shares, shares held in the treasury of the Company,
      shares purchased on the open market or by private purchase or a combination of the foregoing.

   

  
    3 

    
      
 

  

  

   

  (f)       Substitute Awards. Awards may, in the sole discretion of the Committee, be granted under the Plan in assumption of, or in substitution for, outstanding awards previously
      granted by an entity directly or indirectly acquired by the Company or with which the Company combines (“Substitute Awards”). Substitute Awards shall not be counted against the Plan Share Reserve; provided, that Substitute Awards
      issued in connection with the assumption of, or in substitution for, outstanding options intended to qualify as “incentive stock options” within the meaning of Section 422 of the Code shall be counted against the aggregate number of shares of Common
      Stock available for Awards of Incentive Stock Options under the Plan. Subject to applicable stock exchange requirements, available shares under a stockholder-approved plan of an entity directly or indirectly acquired by the Company or with which the
      Company combines (as appropriately adjusted to reflect the acquisition or combination transaction) may be used for Awards under the Plan and shall not reduce the number of shares of Common Stock available for issuance under the Plan.

   

  (g)       Limits and Assumption Date. In all
      cases with respect to each of the foregoing limits in Sections 5(b) and 5(c) above the specified limits or values will be reduced by the amount of any PRA Health Sciences Inc. common stock that was issued in settlement of the respective outstanding
      awards under the Plan prior to the Assumption Date.

   

  		6	Eligibility. Participation in the Plan shall be limited to Eligible Persons.

   

  		7	Options.

   

  (a)       General. Each Option granted under the Plan shall be evidenced by an Award Agreement, which agreement need not be the same for each Participant. Each Option so granted shall
      be subject to the conditions set forth in this Section 7, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. All Options granted under the Plan shall be Nonqualified Stock Options unless
      the applicable Award Agreement expressly states that the Option is intended to be an Incentive Stock Option. Incentive Stock Options shall be granted only to Eligible Persons who are employees of a member of the Company Group, and no Incentive Stock
      Option shall be granted to any Eligible Person who is ineligible to receive an Incentive Stock Option under the Code. No Option shall be treated as an Incentive Stock Option unless the Plan has been approved by the stockholders of the Company in a
      manner intended to comply with the stockholder approval requirements of Section 422(b)(1) of the Code, provided that any Option intended to be an Incentive Stock Option shall not fail to be effective solely on account of a failure to obtain
      such approval, but rather such Option shall be treated as a Nonqualified Stock Option unless and until such approval is obtained. In the case of an Incentive Stock Option, the terms and conditions of such grant shall be subject to, and comply with,
      such rules as may be prescribed by Section 422 of the Code. If for any reason an Option intended to be an Incentive Stock Option (or any portion thereof) shall not qualify as an Incentive Stock Option, then, to the extent of such nonqualification,
      such Option or portion thereof shall be regarded as a Nonqualified Stock Option appropriately granted under the Plan.

   

  (b)       Exercise Price. Except as otherwise provided by the Committee in the case of Substitute Awards, the exercise price (“Exercise Price”) per share of Common Stock for each
      Option shall not be less than 100% of the Grant Date Fair Market Value of such share; provided, however, that in the case of an Incentive Stock Option granted to an employee who, at the time of the grant of such Option, owns stock
      representing more than 10% of the voting power of all classes of stock of any member of the Company Group, the Exercise Price per share shall not be less than 110% of the Grant Date Fair Market Value per share.

   

  (c)       Vesting and Expiration.

   

  (i)       Subject to the Minimum Vesting Condition, Options shall vest and become exercisable in such manner and on such date or dates or upon such event or events as determined by the
      Committee.

   

  
    4 

    
      
 

  

  

   

  (ii)       Options shall expire upon a date determined by the Committee, not to exceed ten (10) years from the Date of Grant (the “Option Period”); provided, that if the Option
      Period (other than in the case of an Incentive Stock Option) would expire at a time when trading in the shares of Common Stock is prohibited by the Company’s securities trading policy (or Company-imposed “blackout period”), then the Option Period
      shall be automatically extended until the thirtieth (30th) day following the expiration of such prohibition. Notwithstanding the foregoing, in no event shall the Option Period exceed five (5) years from the Date of Grant in the case of an Incentive
      Stock Option granted to a Participant who on the Date of Grant owns stock representing more than 10% of the voting power of all classes of stock of any member of the Company Group.

   

  (iii)       Unless otherwise provided by the Committee, whether in an Award Agreement or otherwise, in the event of: (A) a Participant’s Termination by the Service Recipient for Cause, all
      outstanding Options granted to such Participant shall immediately terminate and expire; (B) a Participant’s Termination due to death or Disability, each outstanding unvested Option granted to such Participant shall immediately terminate and expire,
      and each outstanding vested Option shall remain exercisable for one year thereafter (but in no event beyond the expiration of the Option Period); and (C) a Participant’s Termination for any other reason, each outstanding unvested Option granted to
      such Participant shall immediately terminate and expire, and each outstanding vested Option shall remain exercisable for ninety (90) days thereafter (but in no event beyond the expiration of the Option Period).

   

  (d)       Method of Exercise and Form of Payment. No shares of Common Stock shall be issued pursuant to any exercise of an Option until payment in full of the Exercise Price therefor is
      received by the Company and the Participant has paid to the Company an amount equal to any Federal, state, local and non-U.S. income, employment and any other applicable taxes required to be withheld. Options which have become exercisable may be
      exercised by delivery of written or electronic notice of exercise to the Company (or telephonic instructions to the extent provided by the Committee) in accordance with the terms of the Option accompanied by payment of the Exercise Price. Subject to
      applicable law, the Exercise Price shall be payable: (i) in cash, check, cash equivalent and/or shares of Common Stock valued at the Fair Market Value at the time the Option is exercised (including, pursuant to procedures approved by the Committee,
      by means of attestation of ownership of a sufficient number of shares of Common Stock in lieu of actual issuance of such shares to the Company); provided, that such shares of Common Stock are not subject to any pledge or other security
      interest and have been held by the Participant for at least six (6) months (or such other period as established from time to time by the Committee in order to avoid adverse accounting treatment applying generally accepted accounting principles (“GAAP”));

      or (ii) by such other method as the Committee may permit, in its sole discretion, including, without limitation (A) in other property having a fair market value on the date of exercise equal to the Exercise Price; (B) by means of a broker-assisted
      “cashless exercise” pursuant to which the Company is delivered (including telephonically to the extent permitted by the Committee) a copy of irrevocable instructions to a stockbroker to sell the shares of Common Stock otherwise issuable upon the
      exercise of the Option and to deliver promptly to the Company an amount equal to the Exercise Price; or (C) a “net exercise” procedure effected by withholding the minimum number of shares of Common Stock otherwise issuable in respect of an Option
      that are needed to pay the Exercise Price. Any fractional shares of Common Stock shall be settled in cash.

   

  (e)       Notification upon Disqualifying Disposition of an Incentive Stock Option. Each Participant awarded an Incentive Stock Option under the Plan shall notify the Company in writing
      immediately after the date the Participant makes a disqualifying disposition of any Common Stock acquired pursuant to the exercise of such Incentive Stock Option. A disqualifying disposition is any disposition (including, without limitation, any
      sale) of such Common Stock before the later of (i) the date that is two (2) years after the Date of Grant of the Incentive Stock Option, or (ii) the date that is one (1) year after the date of exercise of the Incentive Stock Option. The Company may,
      if determined by the Committee and in accordance with procedures established by the Committee, retain possession, as agent for the applicable Participant, of any Common Stock acquired pursuant to the exercise of an Incentive Stock Option until the
      end of the period described in the preceding sentence, subject to complying with any instructions from such Participant as to the sale of such Common Stock.

   

  
    5 

    
      
 

  

  

   

  (f)       Compliance With Laws, etc. Notwithstanding the foregoing, in no event shall a Participant be permitted to exercise an Option in a manner which the Committee determines would
      violate the Sarbanes-Oxley Act of 2002, as it may be amended from time to time, or any other applicable law or the applicable rules and regulations of the Securities and Exchange Commission or the applicable rules and regulations of any securities
      exchange or inter-dealer quotation system on which the securities of the Company are listed or traded.

   

  		8	Restricted Stock and Restricted Stock Units.

   

  (a)       General. Each grant of Restricted Stock and Restricted Stock Units shall be evidenced by an Award Agreement. Each Restricted Stock and Restricted Stock Unit so granted shall
      be subject to the conditions set forth in this Section 8, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

   

  (b)       Stock Certificates and Book-Entry; Escrow or Similar Arrangement. Upon the grant of Restricted Stock, the Committee shall cause a stock certificate registered in the name of
      the Participant to be issued or shall cause share(s) of Common Stock to be registered in the name of the Participant and held in book-entry form subject to the Company’s directions and, if the Committee determines that the Restricted Stock shall be
      held by the Company or in escrow rather than issued to the Participant pending the release of the applicable restrictions, the Committee may require the Participant to additionally execute and deliver to the Company (i) an escrow agreement
      satisfactory to the Committee, if applicable; and (ii) the appropriate stock power (endorsed in blank) with respect to the Restricted Stock covered by such agreement. Subject to the restrictions set forth in this Section 8, Section 13(c) of the Plan
      and the applicable Award Agreement, a Participant generally shall have the rights and privileges of a stockholder as to shares of Restricted Stock, including, without limitation, the right to vote such Restricted Stock. To the extent shares of
      Restricted Stock are forfeited, any stock certificates issued to the Participant evidencing such shares shall be returned to the Company, and all rights of the Participant to such shares and as a stockholder with respect thereto shall terminate
      without further obligation on the part of the Company. A Participant shall have no rights or privileges as a stockholder as to Restricted Stock Units.

   

  (c)       Vesting. Subject to the Minimum Vesting Condition, Restricted Stock and Restricted Stock Units shall vest, and any applicable Restricted Period shall lapse, in such manner and
      on such date or dates or upon such event or events as determined by the Committee.

   

  (d)       Issuance of Restricted Stock and Settlement of Restricted Stock Units.

   

  (i)       Upon the expiration of the Restricted Period with respect to any shares of Restricted Stock, the restrictions set forth in the applicable Award Agreement shall be of no further force
      or effect with respect to such shares, except as set forth in the applicable Award Agreement. If an escrow arrangement is used, upon such expiration, the Company shall issue to the Participant, or the Participant’s beneficiary, without charge, the
      stock certificate (or, if applicable, a notice evidencing a book-entry notation) evidencing the shares of Restricted Stock which have not then been forfeited and with respect to which the Restricted Period has expired (rounded down to the nearest
      full share).

   

  (ii)       Unless otherwise provided by the Committee in an Award Agreement or otherwise, upon the expiration of the Restricted Period with respect to any outstanding Restricted Stock Units,
      the Company shall issue to the Participant or the Participant’s beneficiary, without charge, one (1) share of Common Stock (or other securities or other property, as applicable) for each such outstanding Restricted Stock Unit; provided, however,
      that the Committee may, in its sole discretion, elect to (A) pay cash or part cash and part shares of Common Stock in lieu of issuing only shares of Common Stock in respect of such Restricted Stock Units; or (B) defer the issuance of shares of Common
      Stock (or cash or part cash and part shares of Common Stock, as the case may be) beyond the expiration of the Restricted Period if such extension would not cause adverse tax consequences under Section 409A of the Code. If a cash payment is made in
      lieu of issuing shares of Common Stock in respect of such Restricted Stock Units, the amount of such payment shall be equal to the Fair Market Value per share of the Common Stock as of the date on which the Restricted Period lapsed with respect to
      such Restricted Stock Units.

   

  
    6 

    
      
 

  

  

   

  (e)       Legends on Restricted Stock. Each certificate, if any, or book entry representing Restricted Stock awarded under the Plan, if any, shall bear a legend or book entry notation
      substantially in the form of the following, in addition to any other information the Company deems appropriate, until the lapse of all restrictions with respect to such shares of Common Stock:

   

  TRANSFER OF THIS CERTIFICATE AND THE SHARES OF COMMON STOCK REPRESENTED
      HEREBY IS RESTRICTED PURSUANT TO THE TERMS OF THE PRA HEALTH SCIENCES, INC. 2018 SHARE INCENTIVE PLAN AND A RESTRICTED STOCK AWARD AGREEMENT BETWEEN PRA HEALTH SCIENCES, INC. AND PARTICIPANT. A COPY OF SUCH PLAN AND AWARD AGREEMENT IS ON FILE AT THE
      PRINCIPAL EXECUTIVE OFFICES OF PRA HEALTH SCIENCES, INC.

   

  		9	Other Equity-Based Awards. The Committee may grant Other Equity-Based Awards under the Plan,
            denominated in shares of Common Stock or based upon the value or otherwise related to the of shares of Common Stock, to Eligible Persons, alone or in tandem with other Awards, in such amounts and, subject to the Minimum Vesting Condition,
            dependent on such other conditions as the Committee shall from time to time in its sole discretion determine. Each Other Equity-Based Award granted under the Plan shall be evidenced by an Award Agreement and shall be subject to such conditions
            not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

   

  		10	Non-Employee Director Grants.

   

  (a)       The Committee may, subject to Section 5(c) hereof, grant Awards to Non- Employee Directors (a “Director Award”), subject to the terms of this Section 10.

   

  (b)       The form of any Director Award, as well as the vesting and other applicable conditions of a Director Award, shall be determined by the Board prior to the applicable Date of Grant.
      Notwithstanding anything contained in the Plan to the contrary, in the event that a Non- Employee Director undergoes a Terminationon the date of a regularly scheduled annual meeting of the stockholders of the Company that is prior to the first
      anniversary of the Date of Grant of any Director Award as a result of such Non-Employee Director not being reelected for another term as a Non-Employee Director, the Director Award (or portion thereof) otherwise scheduled to vest on such first
      anniversary of the Date of Grant shall immediately vest upon such Termination, and such Director Award (or portion thereof) that vests as a result of this sentence shall count against the Minimum Vesting Condition Carve Out Amount (and to the extent
      that the number of shares of Common Stock subject to any such vesting would exceed the remaining Minimum Vesting Condition Carve Out Amount, vesting shall not occur with respect to any any such shares in excess of such Minimum Vesting Condition Carve
      Out Amount and shall be forfeited).

   

  		11	Changes in Capital Structure and Similar Events. Notwithstanding any other provision in this
            Plan to the contrary, the following provisions shall apply to all Awards granted hereunder

   

  (a)       General. In the event of (i) any dividend (other than regular cash dividends) or other distribution (whether in the form of cash, shares of Common Stock, other securities or
      other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, split-off, spin-off, combination, repurchase or exchange of shares of Common Stock or other securities of the Company, issuance of
      warrants or other rights to acquire shares of Common Stock or other securities of the Company, or other similar corporate transaction or event that affects the shares of Common Stock (including a Change in Control); or (ii) unusual or nonrecurring
      events affecting the Company, including changes in applicable rules, rulings, regulations or other requirements, that the Committee determines, in its sole discretion, could result in substantial dilution or enlargement of the rights intended to be
      granted to, or available for, Participants (any event in (i) or (ii), an “Adjustment Event”), the Committee shall, in respect of any such Adjustment Event, make such proportionate substitution or adjustment, if any, as it deems equitable, to
      any or all of (A) the Plan Share Reserve, or any other limit applicable under the Plan with respect to the number of Awards which may be granted hereunder; (B) the number of shares of Common Stock or other securities of the Company (or number and
      kind of other securities or other property) which may be issued in respect of Awards or with respect to which Awards may be granted under the Plan or any Sub- Plan; and (C) the terms of any outstanding Award, including, without limitation, (I) the
      number of shares of Common Stock or other securities of the Company (or number and kind of other securities or other property) subject to outstanding Awards or to which outstanding Awards relate; (II) the Exercise Price or SAR Base Price with respect
      to any Option or SAR, as applicable or any amount payable as a condition of issuance of shares of Common Stock (in the case of any other Award) (provided that in no event shall the per share price of an award be reduced to an amount that is lower
      than the nominal value of a Share); or (III) any applicable performance measures; provided, that in the case of any “equity restructuring” (within the meaning of the Financial Accounting Standards Board Accounting Standards Codification Topic
      718 (or any successor pronouncement thereto)), the Committee shall make an equitable or proportionate adjustment to outstanding Awards to reflect such equity restructuring.

   

  
    7 

    
      
 

  

  

   

  (b)       Change in Control. In the event of a Change in Control, without limiting the foregoing and unless otherwise determined by the Committee (which determination may not include
      any accelerated vesting, except as provided in this Section 11(b)), in its sole discretion, the following provisions shall apply.

   

  (i)       Outstanding Awards with Time-Based Vesting. All outstanding Awards subject to vesting based on the Participant’s continued service over a period of time (“Time-Based Awards”)
      shall be assumed by the surviving or acquiring entity, or its Affiliates (the “Continuing Entity”), or substituted for new cash or equity-based awards of such Continuing Entity, as provided in the merger or acquisition agreement, or if no such
      assumption or substitution is provided for, all outstanding Time-Based Awards shall become fully vested and, to the extent applicable, exercisable and all forfeiture restrictions on such Awards shall lapse. To the extent that any Time-Based Awards
      are to be assumed or substituted, the Committee may provide that the vesting of any unvested portion of any one or more of such Awards will automatically accelerate upon a Participant’s Qualifying Termination.

   

  (ii)       Outstanding Awards with Performance-Based Vesting. All outstanding unvested Awards subject to vesting based on the achievement of performance criteria (“Performance-Based
        Awards”) shall vest as of the effective date of the Change in Control (A) at the target level, pro-rated to reflect the portion of the performance period that has elapsed as of the effective date of the Change in Control or (B) at the actual
      achievement level, based on the actual achievement of such performance criteria, as of the effective date of the Change in Control or the most recent practicable date immediately prior to the effective date of the Change in Control on which the
      performance criteria may be measured prior to such effective date, as reasonably determined by the Committee in good faith, including any reasonable assumptions, adjustments or projections related to such performance criteria. The level of vesting
      for each outstanding Performance-Based Award on a Change in Control as between clause (A) or (B) above shall be the level that provides the greatest value under each Performance-Based Award, which may be different with respect to each outstanding
      Performance-Based Award. Any unvested portion of any outstanding Performance- Based Award that does not become vested in connection with a Change in Control in accordance with this Section 11(b)(ii) shall terminate and cease to be outstanding as of
      the effective date of the Change in Control, without payment of any consideration to the Participant.

   

  (iii)       Cancellation of Awards. In connection with a Change in Control, the Committee may, in its sole discretion, but shall not be obligated to, provide for cancellation of all or
      any portion of any one or more outstanding Awards and payment to the holders of such Awards, with respect to the portion of such Awards that are vested as of such cancellation (including, without limitation, any Awards that would vest in accordance
      with the terms of such Award or in accordance with this Section 11(b)(i) or (ii) hereof, as applicable), the value of the vested portion of such Awards, if any, as determined by the Committee (which value, if applicable, may be based upon the per-
      share consideration received or to be received by the holders of the shares of Common Stock upon the occurrence of the Change in Control (the “Change in Control Consideration”), including, without limitation, in the case of an outstanding
      Option or SAR, a cash payment in an amount equal to the excess, if any, of the Change in Control Consideration over the per-share Exercise Price or SAR Base Price, as applicable, of such Option or SAR, multiplied by the number of shares of Common
      Stock underlying the vested portion of each such Option or SAR. Payments to holders with respect to the vested portion of such cancelled Awards pursuant to this Section 11(b)(iii) shall be made in cash or, in the sole discretion of the Committee, in
      such other form of consideration necessary for such holders to receive the property, cash, securities, and/or other consideration (or any combination thereof) as such holders would have been entitled to receive upon the occurrence of the Change in
      Control as if such holders had been, immediately prior to such Change in Control, the holder of the number of shares of Common Stock covered by the vested portion of such cancelled Awards (less any applicable Exercise or SAR Base Price). The unvested
      portion of any outstanding Award, and the vested portion of any Option or SAR having an Exercise or Strike Price equal to, or in excess of, the Change in Control Consideration, may be canceled and terminated without any payment or consideration
      therefor.

   

  
    8 

    
      
 

  

  

   

  For purposes of Section 11(b)(i) above, the assumption or substitution of
      an Award may include conversion of the shares of Common Stock underlying such Award into shares of the Continuing Entity, or, subject to any limitations or reductions as may be necessary to comply with Section 409A of the Code, into cash, property or
      other securities having an equivalent value as the Award, which conversion shall not affect any continued vesting requirements of the Award (other than as provided in clause (i) above upon a Participant’s Qualifying Termination). For the avoidance of
      doubt, any such substitution of an Award shall not provide for the acceleration of any vesting requirements of the Award (other than as provided in clause (i) above upon a Participant’s Termination) and no Awards shall vest solely as a result of such
      assumption or substitution.

   

  (c)       Other Requirements. Prior to any payment or adjustment contemplated under this Section 11, the Committee may require a Participant to (i) represent and warrant as to the
      unencumbered title to the Participant’s Awards; (ii) bear such Participant’s pro rata share of any post-closing indemnity obligations, and be subject to the same post-closing purchase price adjustments, escrow terms, offset rights, holdback terms,
      and similar conditions as the other holders of Common Stock, subject to any limitations or reductions as may be necessary to comply with Section 409A of the Code; and (iii) deliver customary transfer documentation as reasonably determined by the
      Committee.

   

  (d)       Fractional Shares. Any adjustment provided under this Section 11 may provide for the elimination of any fractional share that might otherwise become subject to an Award.

   

  (e)       Binding Effect. Any adjustment, substitution, determination of value or other action taken by the Committee under this Section 11 shall be conclusive and binding for all
      purposes.

   

  		12	Amendments and Termination.

   

  (a)       Amendment and Termination of the Plan. The Board may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof at any time; provided, that no
      such amendment, alteration, suspension, discontinuance or termination shall be made without stockholder approval if (i) such approval is necessary to comply with any regulatory requirement applicable to the Plan (including, without limitation, as
      necessary to comply with any rules or regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company may be listed or quoted) or for changes in GAAP to new accounting standards; (ii) it would materially
      increase the number of securities which may be issued under the Plan (except for increases pursuant to Section 5 or 11 of the Plan); or (iii) it would materially modify the requirements for participation in the Plan; provided, further, that
      any such amendment, alteration, suspension, discontinuance or termination that would materially and adversely affect the rights of any Participant or any holder or beneficiary of any Award theretofore granted shall not to that extent be effective
      without the consent of the affected Participant, holder or beneficiary. Notwithstanding the foregoing, no amendment shall be made to Section 12(c) of the Plan without stockholder approval.

   

  
    9 

    
      
 

  

  

   

  (b)       Amendment of Award Agreements. The Committee may, to the extent consistent with the terms of the Plan and any applicable Award Agreement, waive any conditions or rights under,
      amend any terms of, or alter, suspend, discontinue, cancel or terminate, any Award theretofore granted or the associated Award Agreement, prospectively or retroactively (including after a Participant’s Termination); provided, that, other than
      pursuant to Section 11, any such waiver, amendment, alteration, suspension, discontinuance, cancellation or termination that would materially and adversely affect the rights of any Participant with respect to any Award theretofore granted shall not
      to that extent be effective without the consent of the affected Participant.

   

  (c)       No Repricing. Notwithstanding anything in the Plan to the contrary, without stockholder approval, except as otherwise permitted under Section 11 of the Plan, (i) no amendment
      or modification may reduce the Exercise Price of any Option or the SAR Base Price of any SAR; (ii) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option or SAR (with a lower Exercise Price or SAR Base Price, as
      the case may be) or other Award or cash payment that is greater than the intrinsic value (if any) of the cancelled Option or SAR; and (iii) the Committee may not take any other action which is considered a “repricing” for purposes of the stockholder
      approval rules of any securities exchange or inter- dealer quotation system on which the securities of the Company are listed or quoted.

   

  		13	General.

   

  (a)       Award Agreements. Each Award under the Plan shall be evidenced by an Award Agreement, which shall be delivered to the Participant to whom such Award was granted and shall
      specify the terms and conditions of the Award and any rules applicable thereto, including, without limitation, the effect on such Award of the death, Disability or Termination of a Participant, or of such other events as may be determined by the
      Committee. For purposes of the Plan, an Award Agreement may be in any such form (written or electronic) as determined by the Committee (including, without limitation, a Board or Committee resolution, an employment agreement, a notice, a certificate
      or a letter) evidencing the Award. The Committee need not require an Award Agreement to be signed by the Participant or a duly authorized representative of the Company.

   

  (b)       Nontransferability.

   

  (i)       Each Award shall be exercisable only by such Participant to whom such Award was granted during the Participant’s lifetime, or, if permissible under applicable law, by the
      Participant’s legal guardian or representative. No Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant (unless such transfer is specifically required pursuant to a domestic relations order
      or by applicable law) other than by will or by the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against any member of the Company
      Group; provided, that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance.

   

  (ii)       Notwithstanding the foregoing, the Committee may, in its sole discretion, permit Awards (other than Incentive Stock Options) to be transferred by a Participant, without
      consideration, subject to such rules as the Committee may adopt consistent with any applicable Award Agreement to preserve the purposes of the Plan, to (A) any person who is a “family member” of the Participant, as such term is used in the
      instructions to Form S-8 under the Securities Act or any successor form of registration statement promulgated by the Securities and Exchange Commission (collectively, the “Immediate Family Members”); (B) a trust solely for the benefit of the
      Participant and the Participant’s Immediate Family Members; (C) a partnership or limited liability company whose only partners or stockholders are the Participant and the Participant’s Immediate Family Members; or (D) a beneficiary to whom donations
      are eligible to be treated as “charitable contributions” for federal income tax purposes (each transferee described in clauses (A), (B), (C) and (D) above is hereinafter referred to as a “Permitted Transferee”); provided, that the
      Participant gives the Committee advance written notice describing the terms and conditions of the proposed transfer and the Committee notifies the Participant in writing that such a transfer would comply with the requirements of the Plan.

   

  
    10 

    
      
 

  

  

   

  (iii)       The terms of any Award transferred in accordance with clause (ii) above shall apply to the Permitted Transferee and any reference in the Plan, or in any applicable Award Agreement,
      to a Participant shall be deemed to refer to the Permitted Transferee, except that (A) Permitted Transferees shall not be entitled to transfer any Award, other than by will or the laws of descent and distribution; (B) Permitted Transferees shall not
      be entitled to exercise any transferred Option unless there shall be in effect a registration statement on an appropriate form covering the shares of Common Stock to be acquired pursuant to the exercise of such Option if the Committee determines,
      consistent with any applicable Award Agreement, that such a registration statement is necessary or appropriate; (C) neither the Committee nor the Company shall be required to provide any notice to a Permitted Transferee, whether or not such notice is
      or would otherwise have been required to be given to the Participant under the Plan or otherwise; and (D) the consequences of a Participant’s Termination under the terms of the Plan and the applicable Award Agreement shall continue to be applied with
      respect to the Participant, including, without limitation, that an Option shall be exercisable by the Permitted Transferee only to the extent, and for the periods, specified in the Plan and the applicable Award Agreement.

   

  (c)       Dividends and Dividend Equivalents.

   

  (i)       The Committee may, in its sole discretion, provide a Participant as part of an Award with dividends, dividend equivalents, or similar payments in respect of Awards, payable in cash,
      shares of Common Stock, other securities, other Awards or other property, on a current or deferred basis, on such terms and conditions as may be determined by the Committee in its sole discretion, including, without limitation, payment directly to
      the Participant, withholding of such amounts by the Company subject to vesting of the Award or reinvestment in additional shares of Common Stock.

   

  (ii)       Without limiting the foregoing, unless otherwise provided in the Award Agreement, any dividend otherwise payable in respect of any share of Restricted Stock that remains subject to
      vesting conditions at the time of payment of such dividend shall be retained by the Company and remain subject to the same vesting conditions as the share of Restricted Stock to which the dividend relates.

   

  (iii)       To the extent provided in an Award Agreement, the holder of outstanding Restricted Stock Units shall be entitled to be credited with dividend equivalent payments (upon the payment by
      the Company of dividends on shares of Common Stock) either in cash or, in the sole discretion of the Committee, in shares of Common Stock having a Fair Market Value equal to the amount of such dividends (and interest may, in the sole discretion of
      the Committee, be credited on the amount of cash dividend equivalents at a rate and subject to such terms as determined by the Committee), which accumulated dividend equivalents (and interest thereon, if applicable) shall be payable at the same time
      as the underlying Restricted Stock Units are settled following the date on which the Restricted Period lapses with respect to such Restricted Stock Units, and, if such Restricted Stock Units are forfeited, the Participant shall have no right to such
      dividend equivalent payments (or interest thereon, if applicable).

   

  (d)       Tax Withholding.

   

  (i)       A Participant shall be required to pay to the Company or one or more of its Subsidiaries, as applicable, an amount in cash (by check or wire transfer) equal to the aggregate amount
      of any income, employment and/or other applicable taxes that are statutorily required to be withheld in respect of an Award. Alternatively, the Company or any of its Subsidiaries may elect, in its sole discretion, to satisfy this requirement by
      withholding such amount from any cash compensation or other cash amounts owing to a Participant.

   

  (ii)       Without limiting the foregoing, the Committee may (but is not obligated to), in its sole discretion, permit or require a Participant to satisfy, all or any portion of the minimum
      income, employment and/or other applicable taxes that are statutorily required to be withheld with respect to an Award by (A) the delivery of shares of Common Stock (which are not subject to any pledge or other security interest) that have been both
      held by the Participant and vested for at least six (6) months (or such other period as established from time to time by the Committee in order to avoid adverse accounting treatment under applicable accounting standards) having an aggregate Fair
      Market Value equal to such minimum statutorily required withholding liability (or portion thereof); or (B) having the Company withhold from the shares of Common Stock otherwise issuable or deliverable to, or that would otherwise be retained by, the
      Participant upon the grant, exercise, vesting or settlement of the Award, as applicable, a number of shares of Common Stock with an aggregate Fair Market Value equal to an amount, subject to clause (iii) below, not in excess of such minimum
      statutorily required withholding liability (or portion thereof).

   

  
    11 

    
      
 

  

  

   

  (iii)       The Committee, subject to its having considered the applicable accounting impact of any such determination, has full discretion to allow Participants to satisfy, in whole or in part,
      any additional income, employment and/or other applicable taxes payable by them with respect to an Award by electing to have the Company withhold from the shares of Common Stock otherwise issuable or deliverable to, or that would otherwise be
      retained by, a Participant upon the grant, exercise, vesting or settlement of the Award, as applicable, shares of Common Stock having an aggregate Fair Market Value that is greater than the applicable minimum required statutory withholding liability
      (but such withholding may in no event be in excess of the maximum statutory withholding amount(s) in a Participant’s relevant tax jurisdictions).

   

  (e)       Data Protection. By participating in the Plan or accepting any rights granted under it, each Participant consents to the collection and processing of personal data relating to
      the Participant so that the Company and its Affiliates can fulfill their obligations and exercise their rights under the Plan and generally administer and manage the Plan. This data will include, but may not be limited to, data about participation in
      the Plan and shares offered or received, purchased, or sold under the Plan from time to time and other appropriate financial and other data (such as the date on which the Awards were granted) about the Participant and the Participant’s participation
      in the Plan.

   

  (f)       No Claim to Awards; No Rights to Continued Employment; Waiver. No employee of any member of the Company Group, or other Person, shall have any claim or right to be granted an
      Award under the Plan or, having been selected for the grant of an Award, to be selected for a grant of any other Award. There is no obligation for uniformity of treatment of Participants or holders or beneficiaries of Awards. The terms and conditions
      of Awards and the Committee’s determinations and interpretations with respect thereto need not be the same with respect to each Participant and may be made selectively among Participants, whether or not such Participants are similarly situated.
      Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right to be retained in the employ or service of the Service Recipient or any other member of the Company Group, nor shall it be construed as giving any
      Participant any rights to continued service on the Board. The Service Recipient or any other member of the Company Group may at any time dismiss a Participant from employment or discontinue any consulting relationship, free from any liability or any
      claim under the Plan, unless otherwise expressly provided in the Plan or any Award Agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to have waived any claim to continued exercise or vesting of an Award or to
      damages or severance entitlement related to non-continuation of the Award beyond the period provided under the Plan or any Award Agreement, except to the extent of any provision to the contrary in any written employment contract or other agreement
      between the Service Recipient and/or any member of the Company Group and the Participant, whether any such agreement is executed before, on or after the Date of Grant.

   

  (g)       International Participants. With respect to Participants who reside or work outside of the United States of America, the Committee may, in its sole discretion, amend the terms
      of the Plan and create or amend Sub-Plans or amend outstanding Awards with respect to such Participants in order to conform such terms with the requirements of local law or to obtain more favorable tax or other treatment for a Participant or any
      member of the Company Group.

   

  (h)       Designation and Change of Beneficiary. Each Participant may file with the Committee a written designation of one or more Persons as the beneficiary(ies) who shall be entitled
      to receive the amounts payable with respect to an Award, if any, due under the Plan upon the Participant’s death. A Participant may, from time to time, revoke or change the Participant’s beneficiary designation without the consent of any prior
      beneficiary by filing a new designation with the Committee. The last such designation received by the Committee shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received
      by the Committee prior to the Participant’s death, and in no event shall it be effective as of a date prior to such receipt. If no beneficiary designation is filed by a Participant, the beneficiary shall be deemed to be the Participant’s spouse or,
      if the Participant is unmarried at the time of death, the Participant’s estate.

   

  
    12 

    
      
 

  

  

   

  (i)       Termination. Except as otherwise provided in an Award Agreement, unless determined otherwise by the Committee at any point following such event: (i) neither a temporary
      absence from employment or service due to illness, vacation or leave of absence (including, without limitation, a call to active duty for military service through a Reserve or National Guard unit) nor a transfer from employment or service with one
      member of the Company Group to employment or service with another member of the Company Group (or vice-versa) shall be considered a Termination; and (ii) if a Participant undergoes a Termination of employment, but such Participant continues to
      provide services to the Company Group in a non-employee capacity, such change in status shall not be considered a Termination for purposes of the Plan. Further, unless otherwise determined by the Committee, in the event that any Service Recipient
      ceases to be a member of the Company Group (by reason of sale, divestiture, spin-off or other similar transaction), unless a Participant’s employment or service is transferred to another entity that would constitute a member of the Company Group
      immediately following such transaction, such Participant shall be deemed to have suffered a Termination hereunder as of the date of the consummation of such transaction.

   

  (j)       No Rights as a Stockholder. Except as otherwise specifically provided in the Plan or any Award Agreement, no Person shall be entitled to the privileges of ownership in respect
      of shares of Common Stock which are subject to Awards hereunder until such shares have been issued or delivered to such Person.

   

  (k)       Government and Other Regulations.

   

  (i)       The obligation of the Company to settle Awards in shares of Common Stock or other consideration shall be subject to all applicable laws, rules, and regulations, and to such approvals
      by governmental agencies as may be required. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited from offering to sell or selling, any
      shares of Common Stock pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion of counsel (if the Company
      has requested such an opinion), satisfactory to the Company, that such shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been fully complied with.
      The Company shall be under no obligation to register for sale under the Securities Act any of the shares of Common Stock to be offered or sold under the Plan. The Committee shall have the authority to provide that all shares of Common Stock issued
      under the Plan shall be subject to such stop-transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award Agreement, the Federal securities laws, or the rules, regulations and other requirements of
      the Securities and Exchange Commission, any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted and any other applicable Federal, state, local or non-U.S. laws, rules, regulations and other
      requirements, and, without limiting the generality of Section 8 of the Plan, the Committee may cause a legend or legends to be put on certificates representing shares of Common Stock issued under the Plan to make appropriate reference to such
      restrictions or may cause such Common Stock issued under the Plan in book-entry form to be held subject to the Company’s instructions or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the
      Committee reserves the right to add any additional terms or provisions to any Award granted under the Plan that the Committee, in its sole discretion, deems necessary or advisable in order that such Award complies with the legal requirements of any
      governmental entity to whose jurisdiction the Award is subject.

   

  
    13 

    
      
 

  

  

   

  (ii) The Committee may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions and/or blockage and/or other market considerations would make
      the Company’s acquisition of shares of Common Stock from the public markets, the Company’s issuance of Common Stock to the Participant, the Participant’s acquisition of Common Stock from the Company and/or the Participant’s sale of Common Stock to
      the public markets, illegal, impracticable or inadvisable. If the Committee determines to cancel all or any portion of an Award in accordance with the foregoing, the Company shall, subject to any limitations or reductions as may be necessary to
      comply with Section 409A of the Code, (A) in the case of Options or SARs, provide the Participant with a cash payment or grant of shares of Common Stock, subject to deferred vesting and delivery consistent with the vesting restrictions applicable to
      such Award, equal to the excess of (I) the aggregate Fair Market Value of the shares of Common Stock subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the shares would have been vested
      or issued, as applicable); over (II) the aggregate Exercise Price or SAR Base Price (in the case of an Option or SAR, respectively) or any amount payable to the Company as a condition of issuance of shares of Common Stock (in the case of any other
      Award), or (B) in the case of Restricted Stock, Restricted Stock Units or Other Equity-Based Awards, provide the Participant with a cash payment or grant of shares of Common Stock, subject to deferred vesting and delivery consistent with the vesting
      restrictions applicable to such Award, equal to the value of such Award or the underlying shares in respect thereof.

   

  (l)       No Section 83(b) Elections Without Consent of Company. No election under Section 83(b) of the Code or under a similar provision of law may be made unless expressly permitted
      by the terms of the applicable Award Agreement or by action of the Committee in writing prior to the making of such election. If a Participant, in connection with the acquisition of shares of Common Stock under the Plan or otherwise, is expressly
      permitted to make such election and the Participant makes the election, the Participant shall notify the Company of such election within ten (10) days of filing notice of the election with the Internal Revenue Service or other governmental authority,
      in addition to any filing and notification required pursuant to Section 83(b) of the Code or other applicable provision.

   

  (m)       Payments to Persons Other Than Participants. If the Committee shall find that any Person to whom any amount is payable under the Plan is unable to care for the Participant’s
      affairs because of illness or accident, or is a minor, or has died, then any payment due to such Person or the Participant’s estate (unless a prior claim therefor has been made by a duly appointed legal representative) may, if the Committee so
      directs the Company, be paid to the Participant’s spouse, child, relative, an institution maintaining or having custody of such Person, or any other Person deemed by the Committee to be a proper recipient on behalf of such Person otherwise entitled
      to payment. Any such payment shall be a complete discharge of the liability of the Committee and the Company therefor.

   

  (n)       Nonexclusivity of the Plan. Neither the adoption of the Plan by the Board nor the submission of the Plan to the stockholders of the Company for approval shall be construed as
      creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of equity-based awards otherwise than under the Plan, and such arrangements may be
      either applicable generally or only in specific cases.

   

  (o)       No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between any
      member of the Company Group, on the one hand, and a Participant or other Person, on the other hand. No provision of the Plan or any Award 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 be obligated to 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, except that insofar as they may have become entitled to payment of additional
      compensation by performance of services, they shall have the same rights as other service providers under general law.

   

  (p)       Reliance on Reports. Each member of the Committee and each member of the Board shall be fully justified in acting or failing to act, as the case may be, and shall not be
      liable for having so acted or failed to act in good faith, in reliance upon any report made by the independent public accountant of any member of the Company Group and/or any other information furnished in connection with the Plan by any agent of the
      Company or the Committee or the Board, other than himself or herself.

   

  
    14 

    
      
 

  

  

   

  (q)       Relationship to Other Benefits. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, profit sharing, group
      insurance or other benefit plan of the Company except as otherwise specifically provided in such other plan or as required by applicable law.

   

  (r)       Governing Law. The Plan shall be governed by and construed in accordance with the internal laws of the State of Delaware applicable to contracts made and performed wholly
      within the State of Delaware, without giving effect to the conflict of laws provisions thereof. EACH PARTICIPANT WHO ACCEPTS AN AWARD IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY SUIT, ACTION, OR OTHER PROCEEDING INSTITUTED BY OR AGAINST
      SUCH PARTICIPANT IN RESPECT OF THE PARTICIPANT’S RIGHTS OR OBLIGATIONS HEREUNDER

   

  (s)       Severability. If any provision of the Plan or any Award or Award Agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any
      Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended
      without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be construed or deemed stricken as to such jurisdiction, Person or Award and the remainder of the Plan and any such Award
      shall remain in full force and effect.

   

  (t)       Obligations Binding on Successors. The obligations of the Company under the Plan shall be binding upon any successor corporation or organization resulting from the merger,
      consolidation or other reorganization of the Company, or upon any successor corporation or organization succeeding to substantially all of the assets and business of the Company.

   

  (u)       Section 409A of the Code.

   

  (i)       Notwithstanding any provision of the Plan to the contrary, it is intended that the provisions of the Plan comply with Section 409A of the Code, and all provisions of the Plan shall
      be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A of the Code. Each Participant is solely responsible and liable for the satisfaction of all taxes and penalties that may be
      imposed on or in respect of such Participant in connection with the Plan (including any taxes and penalties under Section 409A of the Code), and neither the Service Recipient nor any other member of the Company Group shall have any obligation to
      indemnify or otherwise hold such Participant (or any beneficiary) harmless from any or all of such taxes or penalties. With respect to any Award that is considered “deferred compensation” subject to Section 409A of the Code, references in the Plan to
      “termination of employment” (and substantially similar phrases) shall mean “separation from service” within the meaning of Section 409A of the Code. For purposes of Section 409A of the Code, each of the payments that may be made in respect of any
      Award granted under the Plan is designated as separate a payment.

   

  (ii)       Notwithstanding anything in the Plan to the contrary, if a Participant is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, no payments in respect of
      any Awards that are “deferred compensation” subject to Section 409A of the Code and which would otherwise be payable upon the Participant’s “separation from service” (as defined in Section 409A of the Code) shall be made to such Participant prior to
      the date that is six (6) months after the date of such Participant’s “separation from service” or, if earlier, the date of the Participant’s death. Following any applicable six (6) month delay, all such delayed payments will be paid in a single lump
      sum on the earliest date permitted under Section 409A of the Code that is also a business day.

   

  
    15 

    
      
 

  

  

   

  (iii)       Unless otherwise provided by the Committee in an Award Agreement or otherwise, in the event that the timing of payments in respect of any Award (that would otherwise be considered
      “deferred compensation” subject to Section 409A of the Code) would be accelerated upon the occurrence of (A) a Change in Control, no such acceleration shall be permitted unless the event giving rise to the Change in Control satisfies the definition
      of a change in the ownership or effective control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation pursuant to Section 409A of the Code; or (B) a Disability, no such acceleration shall be
      permitted unless the Disability also satisfies the definition of “Disability” pursuant to Section 409A of the Code.

   

  (v)       Clawback/Repayment. All Awards shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with (i) any clawback, forfeiture or
      other similar policy adopted by the Board or the Committee and as in effect from time to time; and (ii) applicable law. Further, to the extent that the Participant receives any amount in excess of the amount that the Participant should otherwise have
      received under the terms of the Award for any reason (including, without limitation, by reason of a financial restatement, mistake in calculations or other administrative error), the Participant shall be required to repay any such excess amount to
      the Company.

   

  (w)       Detrimental Activity. Notwithstanding anything to the contrary contained herein, if a Participant has engaged in any Detrimental Activity, as determined by the Committee, the
      Committee may, in its sole discretion, provide for one or more of the following:

   

  (i)       cancellation of any or all of such Participant’s outstanding Awards; and

   

  (ii)       forfeiture and prompt repayment to the Company by the Participant, of any gain realized on the vesting, exercise or settlement of any Awards previously granted to such Participant.

   

  (x)       Right of Offset. The Company will have the right to offset against its obligation to deliver shares of Common Stock (or other property or cash) under the Plan or any Award
      Agreement any outstanding amounts (including, without limitation, travel and entertainment or advance account balances, loans, repayment obligations under any Awards, or amounts repayable to the Company pursuant to tax equalization, housing,
      automobile or other employee programs) that the Participant then owes to any member of the Company Group and any amounts the Committee otherwise deems appropriate pursuant to any tax equalization policy or agreement. Notwithstanding the foregoing, if
      an Award is “deferred compensation” subject to Section 409A of the Code, the Committee will have no right to offset against its obligation to deliver shares of Common Stock (or other property or cash) under the Plan or any Award Agreement if such
      offset could subject the Participant to the additional tax imposed under Section 409A of the Code in respect of an outstanding Award.

   

  (y)       Expenses; Titles and Headings. The expenses of administering the Plan shall be borne by the Company Group. The titles and headings of the sections in the Plan are for
      convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

   

  (z)       Compliance. Notwithstanding any other
      provision of this Plan, (a) the Company shall not be obliged to issue any Shares pursuant to an Award unless at least the nominal value of each such newly issued Share has been fully paid in advance in accordance with applicable law (which
      requirement may mean the holder of an award is obliged to make such payment) and (b) the Company shall not be obliged to issue or deliver any Shares in satisfaction of Awards until all legal and regulatory requirements associated with such issue or
      delivery have been complied with to the satisfaction of the Committee.

      Sciences, Inc., pursuant to which PRA Health Sciences, Inc. became a Subsidiary of the Company, a public limited company incorporated

      of, or which is allocated to, the Committee herein, and which may be so delegated as a matter of law, except for grants of Awards
      to persons (i) who are Non-Employee Directors or otherwise are subject to Section 16 of the Exchange Act or (ii) who are, or who

      of the Committee, may be made at any time and shall be final, conclusive and binding upon all persons or entities, including,
      without limitation, the Company, any of its Affiliates, any Participant, any holder or beneficiary of any Award, and any stockholder

      or any Award hereunder (unless constituting fraud or a willful criminal act or omission). Each Indemnifiable Person shall be indemnified
      and held harmless by the Company against and from any loss, cost, liability, or expense (including attorneys' fees) that may be
      imposed upon or incurred by such Indemnifiable Person in connection with or resulting from any action, suit or proceeding to which
      such Indemnifiable Person may be a party or in which such Indemnifiable Person may be involved by reason of any action taken or
      omitted to be taken or determination made under the Plan or any Award Agreement and against and from any and all amounts paid
      by such Indemnifiable Person with the Company's approval, in settlement thereof, or paid by such Indemnifiable Person in satisfaction
      of any judgment in any such action, suit or proceeding against such Indemnifiable Person, and the Company shall advance to such
      Indemnifiable Person any such expenses promptly upon written request (which request shall include an undertaking by the Indemnifiable
      Person to repay the amount of such advance if it shall ultimately be determined, as provided below, that the Indemnifiable Person
      is not entitled to be indemnified); provided, that the Company shall have the right, at its own expense, to assume and
      defend any such action, suit or proceeding and once the Company gives notice of its intent to assume the defense, the Company
      shall have sole control over such defense with counsel of the Company's choice. The foregoing right of indemnification shall not
      be available to an Indemnifiable Person to the extent that a final judgment or other final adjudication (in either case not subject
      to further appeal) binding upon such Indemnifiable Person determines that the acts, omissions or determinations of such Indemnifiable
      Person giving rise to the indemnification claim resulted from such Indemnifiable Person's fraud or willful criminal act or omission
      or that such right of indemnification is otherwise prohibited by law or by the Company's or any Subsidiary's organizational documents.
      The foregoing right of indemnification shall not be exclusive of or otherwise supersede any other rights of indemnification to
      which such Indemnifiable Persons may be entitled under the Company's Certificate of Incorporation or Bylaws, as a matter of law,
      individual indemnification agreement or contract or otherwise, or any other power that the Company may have to indemnify such
      Indemnifiable Persons or hold them harmless.

      of the NASDAQ or any other securities exchange or inter-dealer quotation system on which the Common Stock is listed or quoted.
      In any such case, the Board shall have all the authority granted to the Committee under the Plan.

      denominated Performance Compensation Award is paid in cash, other securities, other Awards or other property, no more than the
      Fair Market Value of such shares of Common Stock on the last day of the Performance Period to which such Award relates; (v) the
      maximum number of shares of Common Stock subject to Awards granted during a single fiscal year to any Non- Employee Director,
      taken together with any cash fees paid to such Non-Employee Director during the fiscal year, shall not exceed $500,000 in total
      value (calculating the value of any such Awards based on the grant date fair value of such Awards for financial reporting purposes);
      and (vi) the maximum amount that can be paid to any individual Participant for a single fiscal year during a Performance Period
      (or with respect to each single fiscal year in the event a Performance Period extends beyond a single fiscal year) pursuant to
      a Performance Compensation Award denominated in cash (described in Section 11(a) of the Plan) shall be $7,500,000 provided,
        however, that in all cases with respect to each of the foregoing limits in parts (i), (ii), (iii), (iv), (v) and (vi) the
      specified limits or values will be reduced by the amount of any PRA Health Sciences Inc. common stock that was issued in settlement
      of the respective outstanding awards under the Plan prior to the Assumption Date.

   

  (c)      Other
      than with respect to Substitute Awards, to the extent that an Award expires or is canceled, forfeited, terminated, settled in
      cash, or otherwise is settled without delivery to the Participant of the full number of shares of Common Stock to which the Award
      related, the undelivered shares will again be available for grant. Shares of Common Stock withheld in payment of the exercise
      price or taxes relating to an Award and shares equal to the number of shares surrendered in payment of any Exercise Price or Strike
      Price, or taxes relating to an Award, shall be deemed to constitute shares not issued to the Participant and shall be deemed to
      again be available for Awards under the Plan; provided, however, that such shares shall not become available for issuance
      hereunder if either: (i) the applicable shares are withheld or surrendered following the termination of the Plan; or (ii) at the
      time the applicable shares are withheld or surrendered, it would constitute a material revision of the Plan subject to stockholder
      approval under any then-applicable rules of the national securities exchange on which the Common Stock is listed.

   

  (d)      Shares
      of Common Stock issued by the Company in settlement of Awards may be authorized and unissued shares, shares held in the treasury
      of the Company, shares purchased on the open market or by private purchase or a combination of the foregoing.

   

  (e)      Awards
      may, in the sole discretion of the Committee, be granted under the Plan in assumption of, or in substitution for, outstanding
      awards previously granted by an entity directly or indirectly acquired by the Company or with which the Company combines ("Substitute
        Awards"). Substitute Awards shall not be counted against the Absolute Share Limit; provided, that Substitute Awards
      issued in connection with the assumption of, or in substitution for, outstanding options intended to qualify as "incentive
      stock options" within the meaning of Section 422 of the Code shall be counted against the aggregate number of shares of Common
      Stock available for Awards of Incentive Stock Options under the Plan. Subject to applicable stock exchange requirements, available
      shares under a stockholder approved plan of an entity directly or indirectly acquired by the Company or with which the Company
      combines (as appropriately adjusted to reflect the acquisition or combination transaction) may be used for Awards under the Plan
      and shall not reduce the number of shares of Common Stock available for issuance under the Plan.

   

  
    8 

    
      

    

  

   

  		6	Eligibility. Participation in the Plan shall be limited to Eligible Persons.

   

  		7	Options.

   

  (a)      General.
      Each Option granted under the Plan shall be evidenced by an Award Agreement, in written or electronic form, which agreement need
      not be the same for each Participant. Each Option so granted shall be subject to the conditions set forth in this Section 7, and
      to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. All Options granted
      under the Plan shall be Nonqualified Stock Options unless the applicable Award Agreement expressly states that the Option is intended
      to be an Incentive Stock Option. Incentive Stock Options shall be granted only to Eligible Persons who are employees of the Company
      and its Affiliates, and no Incentive Stock Option shall be granted to any Eligible Person who is ineligible to receive an Incentive
      Stock Option under the Code. No Option shall be treated as an Incentive Stock Option unless the Plan has been approved by the
      stockholders of the Company in a manner intended to comply with the stockholder approval requirements of Section 422(b)(1) of
      the Code, provided that any Option intended to be an Incentive Stock Option shall not fail to be effective solely on account
      of a failure to obtain such approval, but rather such Option shall be treated as a Nonqualified Stock Option unless and until
      such approval is obtained. In the case of an Incentive Stock Option, the terms and conditions of such grant shall be subject to,
      and comply with, such rules as may be prescribed by Section 422 of the Code. If for any reason an Option intended to be an Incentive
      Stock Option (or any portion thereof) shall not qualify as an Incentive Stock Option, then, to the extent of such nonqualification,
      such Option or portion thereof shall be regarded as a Nonqualified Stock Option appropriately granted under the Plan.

   

  (b)      Exercise
        Price. Except as otherwise provided by the Committee in the case of Substitute Awards, the exercise price ("Exercise
        Price") per share of Common Stock for each Option shall not be less than 100% of the Fair Market Value of such share
      (determined as of the Date of Grant); provided, however, that in the case of an Incentive Stock Option granted to an employee
      who, at the time of the grant of such Option, owns stock representing more than 10% of the voting power of all classes of stock
      of the Company or any Affiliate, the Exercise Price per share shall be no less than 110% of the Fair Market Value per share on
      the Date of Grant.

   

  (c)       Vesting
        and Expiration; Termination.

   

  (i)       Options
      shall vest and become exercisable in such manner and on such date or dates or upon such events as determined by the Committee;
      provided, however, that notwithstanding any such vesting dates or events, the Committee may in its sole discretion
      accelerate the vesting of any Options at any time and for any reason. Options shall expire upon a date determined by the Committee,
      not to exceed ten (10) years from the Date of Grant (the "Option Period"); provided, that if the Option
      Period (other than in the case of an Incentive Stock Option) would expire at a time when trading in the shares of Common Stock
      is prohibited by the Company's insider trading policy (or Company- imposed "blackout period"), then the Option Period
      shall be automatically extended until the 30th day following the expiration of such prohibition. Notwithstanding the foregoing,
      in no event shall the Option Period exceed five (5) years from the Date of Grant in the case of an Incentive Stock Option granted
      to a Participant who on the Date of Grant owns stock representing more than 10% of the voting power of all classes of stock of
      the Company or any Affiliate.

   

  (ii)       Unless
      otherwise provided by the Committee, whether in an Award Agreement or otherwise, in the event of: (A) a Participant's Termination
      by the Service Recipient for Cause, all outstanding Options granted to such Participant shall immediately terminate and expire;
      (B) a Participant's Termination due to death or Disability, each outstanding unvested Option granted to such Participant shall
      immediately terminate and expire, and each outstanding vested Option shall remain exercisable for one year thereafter (but in
      no event beyond the expiration of the Option Period); and (C) a Participant's Termination for any other reason, each outstanding
      unvested Option granted to such Participant shall immediately terminate and expire, and each outstanding vested Option shall remain
      exercisable for ninety (90) days thereafter (but in no event beyond the expiration of the Option Period).

   

  
    9 

    
      

    

  

   

  (d)      Method
        of Exercise and Form of Payment. No shares of Common Stock shall be issued pursuant to any exercise of an Option until payment
      in full of the Exercise Price therefor is received by the Company and the Participant has paid to the Company an amount equal
      to any Federal, state, local and non-U.S. income, employment and any other applicable taxes required to be withheld. Options which
      have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company (or telephonic
      instructions to the extent provided by the Committee) in accordance with the terms of the Option accompanied by payment of the
      Exercise Price. Subject to applicable law, the Exercise Price shall be payable: (i) in cash, check, cash equivalent and/or shares
      of Common Stock valued at the Fair Market Value at the time the Option is exercised (including, pursuant to procedures approved
      by the Committee, by means of attestation of ownership of a sufficient number of shares of Common Stock in lieu of actual issuance
      of such shares to the Company); provided, that such shares of Common Stock are not subject to any pledge or other security
      interest; or (ii) by such other method as the Committee may permit in its sole discretion, including, without limitation: (A)
      in other property having a fair market value on the date of exercise equal to the Exercise Price; (B) if there is a public market
      for the shares of Common Stock at such time, by means of a broker-assisted "cashless exercise" pursuant to which the
      Company is delivered (including telephonically to the extent permitted by the Committee) a copy of irrevocable instructions to
      a stockbroker to sell the shares of Common Stock otherwise issuable upon the exercise of the Option and to deliver promptly to
      the Company an amount equal to the Exercise Price; or (C) a "net exercise" procedure effected by withholding the minimum
      number of shares of Common Stock otherwise issuable in respect of an Option that are needed to pay the Exercise Price and all
      applicable required withholding and any other applicable taxes. Any fractional shares of Common Stock shall be settled in cash.

   

  (e)      Notification
        upon Disqualifying Disposition of an Incentive Stock Option. Each Participant awarded an Incentive Stock Option under the
      Plan shall notify the Company in writing immediately after the date he or she makes a disqualifying disposition of any Common
      Stock acquired pursuant to the exercise of such Incentive Stock Option. A disqualifying disposition is any disposition (including,
      without limitation, any sale) of such Common Stock before the later of (A) two years after the Date of Grant of the Incentive
      Stock Option or (B) one year after the date of exercise of the Incentive Stock Option. The Company may, if determined by the Committee
      and in accordance with procedures established by the Committee, retain possession, as agent for the applicable Participant, of
      any Common Stock acquired pursuant to the exercise of an Incentive Stock Option until the end of the period described in the preceding
      sentence, subject to complying with any instructions from such Participant as to the sale of such Common Stock.

   

  (f)       Compliance
        With Laws, etc. Notwithstanding the foregoing, in no event shall a Participant be permitted to exercise an Option in a manner
      which the Committee determines would violate the Sarbanes-Oxley Act of 2002, as it may be amended from time to time, or any other
      applicable law or the applicable rules and regulations of the Securities and Exchange Commission or the applicable rules and regulations
      of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or traded.

   

  		8	Stock Appreciation Rights.

   

  (a)      General.
      Each SAR granted under the Plan shall be evidenced by an Award Agreement. Each SAR so granted shall be subject to the conditions
      set forth in this Section 8, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable
      Award Agreement. Any Option granted under the Plan may include tandem SARs. The Committee also may award SARs to Eligible Persons
      independent of any Option.

   

  
    10 

    
      

    

  

   

  (b)      Strike
        Price. Except as otherwise provided by the Committee in the case of Substitute Awards, the strike price ("Strike Price")
      per share of Common Stock for each SAR shall not be less than 100% of the Fair Market Value of such share (determined as of the
      Date of Grant). Notwithstanding the foregoing, a SAR granted in tandem with (or in substitution for) an Option previously granted
      shall have a Strike Price equal to the Exercise Price of the corresponding Option.

   

  		(c)	Vesting and Expiration; Termination.

   

  (i)       A
      SAR granted in connection with an Option shall become exercisable and shall expire according to the same vesting schedule and
      expiration provisions as the corresponding Option. A SAR granted independent of an Option shall vest and become exercisable in
      such manner and on such date or dates or upon such events as determined by the Committee; provided, however, that
      notwithstanding any such vesting dates or events, the Committee may, in its sole discretion, accelerate the vesting of any SAR
      at any time and for any reason. SARs shall expire upon a date determined by the Committee, not to exceed ten (10) years from the
      Date of Grant (the "SAR Period"); provided, that if the SAR Period would expire at a time when trading
      in the shares of Common Stock is prohibited by the Company's insider trading policy (or Company- imposed "blackout period"),
      then the SAR Period shall be automatically extended until the 30th day following the expiration of such prohibition.

   

  (ii)       Unless
      otherwise provided by the Committee, whether in an Award Agreement or otherwise, in the event of: (A) a Participant's Termination
      by the Service Recipient for Cause, all outstanding SARs granted to such Participant shall immediately terminate and expire; (B)
      a Participant's Termination due to death or Disability, each outstanding unvested SAR granted to such Participant shall immediately
      terminate and expire, and each outstanding vested SAR shall remain exercisable for one (1) year thereafter (but in no event beyond
      the expiration of the SAR Period); and (C) a Participant's Termination for any other reason, each outstanding unvested SAR granted
      to such Participant shall immediately terminate and expire, and each outstanding vested SAR shall remain exercisable for ninety
      (90) days thereafter (but in no event beyond the expiration of the SAR Period).

   

  (d)      Method
        of Exercise. SARs which have become exercisable may be exercised by delivery of written or electronic notice of exercise to
      the Company in accordance with the terms of the Award, specifying the number of SARs to be exercised and the date on which such
      SARs were awarded.

   

  (e)      Payment.
      Upon the exercise of a SAR, the Company shall pay to the Participant an amount equal to the number of shares subject to the SAR
      that is being exercised multiplied by the excess of the Fair Market Value of one (1) share of Common Stock on the exercise date
      over the Strike Price, less an amount equal to any Federal, state, local and non-U.S. income, employment and any other applicable
      taxes required to be withheld. The Company shall pay such amount in cash, in shares of Common Stock valued at Fair Market Value,
      or any combination thereof, as determined by the Committee. Any fractional shares of Common Stock shall be settled in cash.

   

  		9	Restricted Stock and Restricted Stock Units.

   

  (a)      General.
      Each grant of Restricted Stock and Restricted Stock Units shall be evidenced by an Award Agreement. Each Restricted Stock and
      Restricted Stock Unit so granted shall be subject to the conditions set forth in this Section 9, and to such other conditions
      not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

   

  
    11 

    
      

    

  

   

  (b)      Stock
        Certificates and Book-Entry; Escrow or Similar Arrangement. Upon the grant of Restricted Stock, the Committee shall cause
      a stock certificate registered in the name of the Participant to be issued or shall cause share(s) of Common Stock to be registered
      in the name of the Participant and held in book-entry form subject to the Company's directions and, if the Committee determines
      that the Restricted Stock shall be held by the Company or in escrow rather than issued to the Participant pending the release
      of the applicable restrictions, the Committee may require the Participant to additionally execute and deliver to the Company (i)
      an escrow agreement satisfactory to the Committee, if applicable and (ii) the appropriate stock power (endorsed in blank) with
      respect to the Restricted Stock covered by such agreement. If a Participant shall fail to execute and deliver (in a manner permitted
      under Section 14(a) of the Plan or as otherwise determined by the Committee) an agreement evidencing an Award of Restricted Stock
      and, if applicable, an escrow agreement and blank stock power within the amount of time specified by the Committee, the Award
      shall be null and void. Subject to the restrictions set forth in this Section 9 and the applicable Award Agreement, the Participant
      generally shall have the rights and privileges of a stockholder as to such Restricted Stock, including, without limitation, the
      right to vote such Restricted Stock; provided, that if the lapsing of restrictions with respect to any grant of Restricted
      Stock is contingent on satisfaction of performance conditions (other than, or in addition to, the passage of time), any dividends
      payable on such shares of Restricted Stock shall be held by the Company and delivered (without interest) to the Participant within
      fifteen (15) days following the date on which the restrictions on such Restricted Stock lapse (and the right to any such accumulated
      dividends shall be forfeited upon the forfeiture of the Restricted Stock to which such dividends relate). To the extent shares
      of Restricted Stock are forfeited, any stock certificates issued to the Participant evidencing such shares shall be returned to
      the Company, and all rights of the Participant to such shares and as a stockholder with respect thereto shall terminate without
      further obligation on the part of the Company.

   

  		(c)	Vesting; Termination.

   

  (i)       Restricted
      Stock and Restricted Stock Units shall vest, and any applicable Restricted Period shall lapse, in such manner and on such date
      or dates or upon such event or events as determined by the Committee; provided, however, that, notwithstanding any
      such dates or events, the Committee may, in its sole discretion, accelerate the vesting of any Restricted Stock or Restricted
      Stock Unit or the lapsing of any applicable Restricted Period at any time and for any reason.

   

  (ii)       Unless
      otherwise provided by the Committee, whether in an Award Agreement or otherwise, in the event of a Participant's Termination for
      any reason prior to the time that such Participant's Restricted Stock or Restricted Stock Units, as applicable, have vested, (x)
      all vesting with respect to such Participant's Restricted Stock or Restricted Stock Units shall cease and (y) unvested shares
      of Restricted Stock and unvested Restricted Stock Units, as applicable, shall be forfeited to the Company by the Participant for
      no consideration as of the date of such Termination.

   

  		(d)	Issuance of Restricted Stock and Settlement of Restricted Stock Units.

   

  (i)       Upon
      the expiration of the Restricted Period with respect to any shares of Restricted Stock, the restrictions set forth in the applicable
      Award Agreement shall be of no further force or effect with respect to such shares, except as set forth in the applicable Award
      Agreement. If an escrow arrangement is used, upon such expiration, the Company shall issue to the Participant, or his or her beneficiary,
      without charge, the stock certificate (or, if applicable, a notice evidencing a book-entry notation) evidencing the shares of
      Restricted Stock which have not then been forfeited and with respect to which the Restricted Period has expired (rounded down
      to the nearest full share). Dividends, if any, that may have been withheld by the Committee and attributable to any particular
      share of Restricted Stock shall be distributed to the Participant in cash or, at the sole discretion of the Committee, in shares
      of Common Stock having a Fair Market Value (on the date of distribution) equal to the amount of such dividends, upon the release
      of restrictions on such share and, if such share is forfeited, the Participant shall have no right to such dividends.

   

  
    12 

    
      

    

  

   

  (ii)       Unless
      otherwise provided by the Committee in an Award Agreement or otherwise, upon the expiration of the Restricted Period with respect
      to any outstanding Restricted Stock Units, the Company shall issue to the Participant or his or her beneficiary, without charge,
      one (1)share of Common Stock (or other securities or other property, as applicable) for each such outstanding Restricted Stock
      Unit; provided, however, that the Committee may, in its sole discretion, elect to (i) pay cash or part cash and part shares
      of Common Stock in lieu of issuing only shares of Common Stock in respect of such Restricted Stock Units; or (ii) defer the issuance
      of shares of Common Stock (or cash or part shares of Common Stock and part cash, as the case may be) beyond the expiration of
      the Restricted Period if such extension would not cause adverse tax consequences under Section 409A of the Code. If a cash payment
      is made in lieu of issuing shares of Common Stock, the amount of such payment shall be equal to the Fair Market Value of the Common
      Stock as of the date on which the Restricted Period lapsed with respect to such Restricted Stock Units. To the extent provided
      in an Award Agreement, the holder of outstanding Restricted Stock Units shall be entitled to be credited with dividend equivalent
      payments (upon the payment by the Company of dividends on shares of Common Stock) either in cash or, at the sole discretion of
      the Committee, in shares of Common Stock having a Fair Market Value equal to the amount of such dividends (and interest may, at
      the sole discretion of the Committee, be credited on the amount of cash dividend equivalents at a rate and subject to such terms
      as determined by the Committee), which accumulated dividend equivalents (and interest thereon, if applicable) shall be payable
      at the same time as the underlying Restricted Stock Units are settled following the release of restrictions on such Restricted
      Stock Units, and, if such Restricted Stock Units are forfeited, the Participant shall have no right to such dividend equivalent
      payments.

   

  (e)      Legends
        on Restricted Stock. Each certificate, if any, representing Restricted Stock awarded under the Plan, if any, shall bear a
      legend substantially in the form of the following, in addition to any other information the Company deems appropriate, until the
      lapse of all restrictions with respect to such shares of Common Stock:

   

  TRANSFER
      OF THIS CERTIFICATE AND THE SHARES REPRESENTED HEREBY IS RESTRICTED PURSUANT TO THE TERMS OF THE PRA HEALTH SCIENCES, INC. 2014
      OMNIBUS INCENTIVE PLAN AND A RESTRICTED STOCK AWARD AGREEMENT BETWEEN PRA HEALTH SCIENCES, INC. AND PARTICIPANT. A COPY OF SUCH
      PLAN AND AWARD AGREEMENT IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF PRA HEALTH SCIENCES, INC.

   

  		10	Other Stock-Based Awards. The Committee may issue unrestricted Common
            Stock, rights to receive grants of Awards at a future date, or other Awards denominated in Common Stock (including, without limitation, performance shares or performance units), under the Plan to Eligible Persons, alone or in tandem with other
            Awards, in such amounts as the Committee shall from time to time in its sole discretion determine. Each Other Stock-Based Award granted under the Plan shall be evidenced by an Award Agreement. Each Other Stock- Based Award so granted shall be
            subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement, including, without limitation, those set forth in Section 14(c) of the Plan.

   

  		11	Performance Compensation Awards.

   

  (a)      General.
      The Committee shall have the authority, at or before the time of grant of any Award, to designate such Award as a Performance
      Compensation Award intended to qualify as "performance-based compensation" under Section 162(m) of the Code. The Committee
      shall also have the authority to make an award of a cash bonus to any Participant and designate such Award as a Performance Compensation
      Award intended to qualify as "performance-based compensation" under Section 162(m) of the Code. Notwithstanding anything
      in the Plan to the contrary, if the Company determines that a Participant who has been granted an Award designated as a Performance
      Compensation Award is not (or is no longer) a "covered employee" (within the meaning of Section 162(m) of the Code),
      the terms and conditions of such Award may be modified without regard to any restrictions or limitations set forth in this Section
      11 (but subject otherwise to the provisions of Section 13 of the Plan).

   

  (b)      Discretion
        of Committee with Respect to Performance Compensation Awards. With regard to a particular Performance Period, the Committee
      shall have sole discretion to select the length of such Performance Period, the type(s) of Performance Compensation Awards to
      be issued, the Performance Criteria that will be used to establish the Performance Goal(s), the kind(s) and/or level(s) of the
      Performance Goal(s) that is (are) to apply and the Performance Formula(e). Within the first ninety (90) days of a Performance
      Period (or, within any other maximum period allowed under Section 162(m) of the Code), the Committee shall, with regard to the
      Performance Compensation Awards to be issued for such Performance Period, exercise its discretion with respect to each of the
      matters enumerated in the immediately preceding sentence and record the same in writing.

   

  
    13 

    
      

    

  

   

  (c)      Performance
        Criteria. The Performance Criteria that will be used to establish the Performance Goal(s) may be based on the attainment of
      specific levels of performance of the Company (and/or one or more Affiliates, divisions or operational and/or business units,
      product lines, brands, business segments, administrative departments, or any combination of the foregoing) and shall be limited
      to the following, which may be determined in accordance with generally accepted accounting principles ("GAAP")
      or on a non-GAAP basis: (i) net earnings, net income (before or after taxes) or consolidated net income; (ii) basic or diluted
      earnings per share (before or after taxes); (iii) net revenue or net revenue growth; (iv) gross revenue or gross revenue growth,
      gross profit or gross profit growth; (v) net operating profit (before or after taxes); (vi) return measures (including, but not
      limited to, return on investment, assets, capital, employed capital, invested capital, equity, or sales); (vii) cash flow measures
      (including, but not limited to, operating cash flow, free cash flow, or cash flow return on capital), which may but are not required
      to be measured on a per share basis; (viii) earnings before or after interest, taxes, depreciation and/or amortization (including
      EBIT and EBITDA); (ix) gross or net operating margins; (x) productivity ratios; (xi) share price (including, but not limited to,
      growth measures and total stockholder return); (xii) expense targets or cost reduction goals, general and administrative expense
      savings; (xiii) operating efficiency; (xiv) objective measures of customer/client satisfaction; (xv) working capital targets;
      (xvi) measures of economic value added or other 'value creation' metrics; (xvii) enterprise value; (xviii) sales; (xix) stockholder
      return; (xx) customer/client retention; (xxi) competitive market metrics; (xxii) employee retention; (xxiii) objective measures
      of personal targets, goals or completion of projects (including but not limited to succession and hiring projects, completion
      of specific acquisitions, dispositions, reorganizations or other corporate transactions or capital-raising transactions, expansions
      of specific business operations and meeting divisional or project budgets); (xxiv) comparisons of continuing operations to other
      operations; (xxv) market share; (xxvi) cost of capital, debt leverage year-end cash position or book value; (xxvii) strategic
      objectives; or (xxviii) any combination of the foregoing. Any one or more of the Performance Criteria may be stated as a percentage
      of another Performance Criteria, or used on an absolute or relative basis to measure the performance of the Company and/or one
      or more Affiliates as a whole or any divisions or operational and/or business units, product lines, brands, business segments,
      administrative departments of the Company and/or one or more Affiliates or any combination thereof, as the Committee may deem
      appropriate, or any of the above Performance Criteria may be compared to the performance of a selected group of comparison companies,
      or a published or special index that the Committee, in its sole discretion, deems appropriate, or as compared to various stock
      market indices. The Committee also has the authority to provide for accelerated vesting of any Award based on the achievement
      of Performance Goals pursuant to the Performance Criteria specified in this paragraph. To the extent required under Section 162(m)
      of the Code, the Committee shall, within the first ninety (90) days of a Performance Period (or, within any other maximum period
      allowed under Section 162(m) of the Code), define in an objective fashion the manner of calculating the Performance Criteria it
      selects to use for such Performance Period.

   

  (d)      Modification
        of Performance Goal(s). In the event that applicable tax and/or securities laws change to permit Committee discretion to alter
      the governing Performance Criteria without obtaining stockholder approval of such alterations, the Committee shall have sole discretion
      to make such alterations without obtaining stockholder approval. Unless otherwise determined by the Committee at the time a Performance
      Compensation Award is granted, the Committee shall, during the first ninety (90) days of a Performance Period (or, within any
      other maximum period allowed under Section 162(m) of the Code), or at any time thereafter to the extent the exercise of such authority
      at such time would not cause the Performance Compensation Awards granted to any Participant for such Performance Period to fail
      to qualify as "performance-based compensation" under Section 162(m) of the Code, specify adjustments or modifications
      to be made to the calculation of a Performance Goal for such Performance Period, based on and in order to appropriately reflect
      the following events: (i) asset write-downs; (ii) litigation or claim judgments or settlements; (iii) the effect of changes in
      tax laws, accounting principles, or other laws or regulatory rules affecting reported results; (iv) any reorganization and restructuring
      programs; (v) extraordinary nonrecurring items as described in Accounting Standards Codification Topic 225-20 (or any successor
      pronouncement thereto) and/or in management's discussion and analysis of financial condition and results of operations appearing
      in the Company's annual report to stockholders for the applicable year; (vi) acquisitions or divestitures; (vii) any other specific,
      unusual or nonrecurring events, or objectively determinable category thereof; (viii) foreign exchange gains and losses; (ix) discontinued
      operations and nonrecurring charges; and (x) a change in the Company's fiscal year.

   

  
    14 

    
      

    

  

   

  (e)      Payment
        of Performance Compensation Awards.

   

  (i)       Condition
        to Receipt of Payment. Unless otherwise provided in the applicable Award agreement, a Participant must be employed by the
      Company on the last day of a Performance Period to be eligible for payment in respect of a Performance Compensation Award for
      such Performance Period.

   

  (ii)      Limitation.
      Unless otherwise provided in the applicable Award agreement, a Participant shall be eligible to receive payment in respect of
      a Performance Compensation Award only to the extent that: (A) the Performance Goals for such period are achieved; and (B) all
      or some of the portion of such Participant's Performance Compensation Award has been earned for the Performance Period based on
      the application of the Performance Formula to such achieved Performance Goals.

   

  (iii)      Certification.
      Following the completion of a Performance Period, the Committee shall review and certify in writing whether, and to what extent,
      the Performance Goals for the Performance Period have been achieved and, if so, calculate and certify in writing that amount of
      the Performance Compensation Awards earned for the period based upon the Performance Formula. The Committee shall then determine
      the amount of each Participant's Performance Compensation Award actually payable for the Performance Period and, in so doing,
      may apply Negative Discretion.

   

  (iv)      Use
        of Negative Discretion. In determining the actual amount of an individual Participant's Performance Compensation Award for
      a Performance Period, the Committee may reduce or eliminate the amount of the Performance Compensation Award earned under the
      Performance Formula in the Performance Period through the use of Negative Discretion. Unless otherwise provided in the applicable
      Award Agreement, the Committee shall not have the discretion to: (A) grant or provide payment in respect of Performance Compensation
      Awards for a Performance Period if the Performance Goals for such Performance Period have not been attained; or (B) increase a
      Performance Compensation Award above the applicable limitations set forth in Section 5 of the Plan.

   

  (f)       Timing
        of Award Payments. Unless otherwise provided in the applicable Award Agreement, Performance Compensation Awards granted for
      a Performance Period shall be paid to Participants as soon as administratively practicable following completion of the certifications
      required by this Section 11. Any Performance Compensation Award that has been deferred shall not (between the date as of which
      the Award is deferred and the payment date) increase (i) with respect to a Performance Compensation Award that is payable in cash,
      by a measuring factor for each fiscal year greater than a reasonable rate of interest set by the Committee or (ii) with respect
      to a Performance Compensation Award that is payable in shares of Common Stock, by an amount greater than the appreciation of a
      share of Common Stock from the date such Award is deferred to the payment date. Any Performance Compensation Award that is deferred
      and is otherwise payable in shares of Common Stock shall be credited (during the period between the date as of which the Award
      is deferred and the payment date) with dividend equivalents (in a manner consistent with the methodology set forth in the last
      sentence of Section 9(d)(ii) of the Plan).

   

  		12	Changes in Capital Structure and Similar Events. In the event of (a) any dividend (other than
            regular cash dividends) or other distribution (whether in the form of cash, shares of Common Stock, other securities or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up,
            split-off, spin-off, combination, repurchase or exchange of shares of Common Stock or other securities of the Company, issuance of warrants or other rights to acquire shares of Common Stock or other securities of the Company, or other similar
            corporate transaction or event (including, without limitation, a Change in Control) that affects the shares of Common Stock, or (b) unusual or nonrecurring events (including, without limitation, a Change in Control) affecting the Company, any
            Affiliate, or the financial statements of the Company or any Affiliate, or changes in applicable rules, rulings, regulations or other requirements of any governmental body or securities exchange or inter-dealer quotation system, accounting
            principles or law, such that in either case an adjustment is determined by the Committee in its sole discretion to be necessary or appropriate, then the Committee shall make any such adjustments in such manner as it may deem equitable,
            including, without limitation, any or all of the following:

   

  
    15 

    
      

    

  

   

  (i)        
      adjusting any or all of (A) the Absolute Share Limit, or any other limit applicable under the Plan with respect to the number
      of Awards which may be granted hereunder; (B) the number of shares of Common Stock or other securities of the Company (or number
      and kind of other securities or other property) which may be issued in respect of Awards or with respect to which Awards may be
      granted under the Plan (including, without limitation, adjusting any or all of the limitations under Section 5 of the Plan); and
      (C) the terms of any outstanding Award, including, without limitation, (1) the number of shares of Common Stock or other securities
      of the Company (or number and kind of other securities or other property) subject to outstanding Awards or to which outstanding
      Awards relate; (2) the Exercise Price or Strike Price with respect to any Award (provided that in no event shall the per share
      price of an award be reduced to an amount that is lower than the nominal value of a share); or (3) any applicable performance
      measures (including, without limitation, Performance Criteria and Performance Goals);

   

  (ii)       
      providing for a substitution or assumption of Awards (or awards of an acquiring company), accelerating the exercisability of,
      lapse of restrictions on, or termination of, Awards or providing for a period of time (which shall not be required to be more
      than ten (10) days) for Participants to exercise outstanding Awards prior to the occurrence of such event (and any such Award
      not so exercised shall terminate upon the occurrence of such event); and

   

  (iii)      
      cancelling any one or more outstanding Awards and causing to be paid to the holders holding vested Awards (including any Awards
      that would vest as a result of the occurrence of such event but for such cancellation) the value of such Awards, if any, as determined
      by the Committee (which, if applicable, may be based upon the price per share of Common Stock received or to be received by other
      stockholders of the Company in such event), including, without limitation, in the case of an outstanding Option or SAR, a cash
      payment in an amount equal to the excess, if any, of the Fair Market Value (as of a date specified by the Committee) of the shares
      of Common Stock subject to such Option or SAR over the aggregate Exercise Price or Strike Price of such Option or SAR, respectively
      (it being understood that, in such event, any Option or SAR having a per share Exercise Price or Strike Price equal to, or in
      excess of, the Fair Market Value of a share of Common Stock subject thereto may be cancelled and terminated without any payment
      or consideration therefor);

   

  provided,
        however,. that in the case of any "equity restructuring" (within the meaning of the Financial Accounting Standards
      Board Accounting Standards Codification Topic 718 (or any successor pronouncement thereto)), the Committee shall make an equitable
      or proportionate adjustment to outstanding Awards to reflect such equity restructuring. Any adjustment in Incentive Stock Options
      under this Section 12 (other than any cancellation of Incentive Stock Options) shall be made only to the extent not constituting
      a "modification" within the meaning of Section 424(h)(3) of the Code, and any adjustments under this Section 12 shall
      be made in a manner which does not adversely affect the exemption provided pursuant to Rule 16b-3 under the Exchange Act. Any
      such adjustment shall be conclusive and binding for all purposes Payments holders pursuant to clause (iii) above shall be made
      in cash or, in the sole discretion of the Committee, in the form of such other consideration necessary for a Participant to receive
      property, cash, or securities (or combination thereof) as such Participant would have been entitled to receive upon the occurrence
      of the transaction if the Participant had been, immediately prior to such transaction, the holder of the number of shares of Common
      Stock covered by the Award at such time (less any applicable Exercise Price or Strike Price). In addition, prior to any payment
      or adjustment contemplated under this Section 12, the Committee may require a Participant to (A) represent and warrant as to the
      unencumbered title to his or her Awards; (B) bear such Participant's pro rata share of any post-closing indemnity obligations,
      and be subject to the same post-closing purchase price adjustments, escrow terms, offset rights, holdback terms, and similar conditions
      as the other holders of Common Stock and (C) deliver customary transfer documentation as reasonably determined by the Committee.

  		13	Amendments and Termination.

   

  (a)      Amendment
        and Termination of the Plan. The Board may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof
      at any time; provided, that no such amendment, alteration, suspension, discontinuation or termination shall be made without
      stockholder approval if: (i) such approval is necessary to comply with any regulatory requirement applicable to the Plan (including,
      without limitation, as necessary to comply with any rules or regulations of any securities exchange or inter-dealer quotation
      system on which the securities of the Company may be listed or quoted) or for changes in GAAP to new accounting standards; (ii)
      it would materially increase the number of securities which may be issued under the Plan (except for increases pursuant to Section
      5 or 12 of the Plan) or (iii) it would materially modify the requirements for participation in the Plan; provided, further,
      that any such amendment, alteration, suspension, discontinuance or termination that would materially and adversely affect the
      rights of any Participant or any holder or beneficiary of any Award theretofore granted shall not to that extent be effective
      without the consent of the affected Participant, holder or beneficiary. Notwithstanding the foregoing, no amendment shall be made
      to the last proviso of Section 13(b) of the Plan without stockholder approval.

   

  (b)      Amendment
        of Award Agreements. The Committee may, to the extent consistent with the terms of any applicable Award Agreement, waive any
      conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate, any Award theretofore granted
      or the associated Award Agreement, prospectively or retroactively (including after a Participant's Termination); provided,
      that any such waiver, amendment, alteration, suspension, discontinuance, cancellation or termination that would materially and
      adversely affect the rights of any Participant with respect to any Award theretofore granted shall not to that extent be effective
      without the consent of the affected Participant; provided, further, that without stockholder approval, except as otherwise
      permitted under Section 12 of the Plan, (i) no amendment or modification may reduce the Exercise Price of any Option or the
      Strike Price of any SAR; (ii) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option or SAR
      (with a lower Exercise Price or Strike Price, as the case may be) or other Award or cash payment that is greater than the intrinsic
      value (if any) of the cancelled Option or SAR and (iii) the Committee may not take any other action which is considered a "repricing"
      for purposes of the stockholder approval rules of any securities exchange or inter-dealer quotation system on which the securities
      of the Company are listed or quoted.

   

  		14	General.

   

  (a)      Award
        Agreements. Each Award under the Plan shall be evidenced by an Award Agreement, which shall be delivered to the Participant
      and shall specify the terms and conditions of the Award and any rules applicable thereto, including, without limitation, the effect
      on such Award of the death, Disability or Termination of a Participant, or of such other events as may be determined by the Committee.
      For purposes of the Plan, an Award Agreement may be in any such form (written or electronic) as determined by the Committee (including,
      without limitation, a Board or Committee resolution, an employment agreement, a notice, a certificate or a letter) evidencing
      the Award. The Committee need not require an Award Agreement to be signed by the Participant or a duly authorized representative
      of the Company.

   

  		(b)	Nontransferability.

   

  (i)       Each
      Award shall be exercisable only by a Participant during the Participant's lifetime, or, if permissible under applicable law, by
      the Participant's legal guardian or representative. No Award may be assigned, alienated, pledged, attached, sold or otherwise
      transferred or encumbered by a Participant (including, without limitation, except as may be prohibited by applicable law, pursuant
      to a domestic relations order) other than by will or by the laws of descent and distribution and any such purported assignment,
      alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or an Affiliate;
      provided, that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale,
      transfer or encumbrance.

   

  
    17 

    
      

    

  

   

  (ii)       Notwithstanding
      the foregoing, the Committee may, in its sole discretion, permit Awards (other than Incentive Stock Options) to be transferred
      by a Participant, without consideration, subject to such rules as the Committee may adopt consistent with any applicable Award
      Agreement to preserve the purposes of the Plan, to: (A) any person who is a "family member" of the Participant, as such
      term is used in the instructions to Form S-8 under the Securities Act or any successor form of registration statement promulgated
      by the Securities and Exchange Commission (collectively, the "Immediate Family Members"); (B) a trust solely
      for the benefit of the Participant and his or her Immediate Family Members; (C) a partnership or limited liability company whose
      only partners or stockholders are the Participant and his or her Immediate Family Members; or (D) a beneficiary to whom donations
      are eligible to be treated as "charitable contributions" for federal income tax purposes (each transferee described
      in clauses (A), (B), (C) and (D) above is hereinafter referred to as a "Permitted Transferee"); provided,
      that the Participant gives the Committee advance written notice describing the terms and conditions of the proposed transfer and
      the Committee notifies the Participant in writing that such a transfer would comply with the requirements of the Plan.

   

  (iii)       The
      terms of any Award transferred in accordance with the immediately preceding sentence shall apply to the Permitted Transferee and
      any reference in the Plan, or in any applicable Award Agreement, to a Participant shall be deemed to refer to the Permitted Transferee,
      except that: (A) Permitted Transferees shall not be entitled to transfer any Award, other than by will or the laws of descent
      and distribution; (B) Permitted Transferees shall not be entitled to exercise any transferred Option unless there shall be in
      effect a registration statement on an appropriate form covering the shares of Common Stock to be acquired pursuant to the exercise
      of such Option if the Committee determines, consistent with any applicable Award Agreement, that such a registration statement
      is necessary or appropriate; (C) the Committee or the Company shall not be required to provide any notice to a Permitted Transferee,
      whether or not such notice is or would otherwise have been required to be given to the Participant under the Plan or otherwise;
      and (D) the consequences of the Termination of the Participant under the terms of the Plan and the applicable Award Agreement
      shall continue to be applied with respect to the Participant, including, without limitation, that an Option shall be exercisable
      by the Permitted Transferee only to the extent, and for the periods, specified in the Plan and the applicable Award Agreement.

   

  (c)      Dividends
        and Dividend Equivalents. The Committee, in its sole discretion, may provide a Participant as part of an Award with dividends,
      dividend equivalents, or similar payments in respect of Awards, payable in cash, shares of Common Stock, other securities, other
      Awards or other property, on a current or deferred basis, on such terms and conditions as may be determined by the Committee in
      its sole discretion, including, without limitation, payment directly to the Participant, withholding of such amounts by the Company
      subject to vesting of the Award or reinvestment in additional shares of Common Stock, Restricted Stock or other Awards; provided,
      that no dividends, dividend equivalents or other similar payments shall be payable in respect of outstanding (i) Options or SARs;
      or (ii) unearned Performance Compensation Awards or other unearned Awards subject to performance conditions (other than, or in
      addition to, the passage of time) (although dividends, dividend equivalents or other similar payments may be accumulated in respect
      of unearned Awards and paid within fifteen (15) days after such Awards are earned and become payable or distributable).

   

  		(d)	Tax Withholding.

   

  (ii)       A
      Participant shall be required to pay to the Company or any Affiliate, and the Company or any Affiliate shall have the right and
      is hereby authorized to withhold, from any cash, shares of Common Stock, other securities or other property issuable or deliverable
      under any Award or from any compensation or other amounts owing to a Participant, the amount (in cash, shares of Common Stock,
      other securities or other property) of any required withholding or any other applicable taxes in respect of an Award, its exercise,
      or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of
      the Committee or the Company to satisfy all obligations for the payment of such withholding or any other applicable taxes.

   

  (iii)       Without
      limiting the generality of clause (i) above, the Committee may, in its sole discretion, permit a Participant to satisfy, in whole
      or in part, the foregoing withholding liability by (A) the delivery of shares of Common Stock (which are not subject to any pledge
      or other security interest) owned by the Participant having a Fair Market Value equal to such withholding liability or (B) having
      the Company withhold from the number of shares of Common Stock otherwise issuable or deliverable pursuant to the exercise or settlement
      of the Award a number of shares with a Fair Market Value equal to such withholding liability, provided that with respect to shares
      withheld pursuant to clause (B), the number of such shares may not have a Fair Market Value greater than the minimum required
      statutory withholding liability.

   

  
    18 

    
      

    

  

   

  (e)      No
        Claim to Awards; No Rights to Continued Employment; Waiver. No employee of the Company or any Affiliate, or other person,
      shall have any claim or right to be granted an Award under the Plan or, having been selected for the grant of an Award, to be
      selected for a grant of any other Award. There is no obligation for uniformity of treatment of Participants or holders or beneficiaries
      of Awards. The terms and conditions of Awards and the Committee's determinations and interpretations with respect thereto need
      not be the same with respect to each Participant and may be made selectively among Participants, whether or not such Participants
      are similarly situated. Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right
      to be retained in the employ or service of the Company or any Affiliate, nor shall it be construed as giving any Participant any
      rights to continued service on the Board. The Company or any of its Affiliates may at any time dismiss a Participant from employment
      or discontinue any consulting relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided
      in the Plan or any Award Agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to have waived
      any claim to continued exercise or vesting of an Award or to damages or severance entitlement related to non-continuation of the
      Award beyond the period provided under the Plan or any Award Agreement, except to the extent of any provision to the contrary
      in any written employment contract or other agreement between the Company and its Affiliates and the Participant, whether any
      such agreement is executed before, on or after the Date of Grant.

   

  (f)       International
        Participants. With respect to Participants who reside or work outside of the United States of America and who are not (and
      who are not expected to be) "covered employees" within the meaning of Section 162(m) of the Code, the Committee may,
      in its sole discretion, amend the terms of the Plan and create or amend Sub-Plans or amend outstanding Awards with respect to
      such Participants in order to conform such terms with the requirements of local law or to obtain more favorable tax or other treatment
      for a Participant, the Company or its Affiliates.

   

  (g)      Designation
        and Change of Beneficiary. Each Participant may file with the Committee a written designation of one or more persons as the
      beneficiary(ies) who shall be entitled to receive the amounts payable with respect to an Award, if any, due under the Plan upon
      his or her death. A Participant may, from time to time, revoke or change his or her beneficiary designation without the consent
      of any prior beneficiary by filing a new designation with the Committee. The last such designation received by the Committee shall
      be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received
      by the Committee prior to the Participant's death, and in no event shall it be effective as of a date prior to such receipt. If
      no beneficiary designation is filed by a Participant, the beneficiary shall be deemed to be his or her spouse or, if the Participant
      is unmarried at the time of death, his or her estate.

   

  (h)      Termination.
      Except as otherwise provided in an Award Agreement, unless determined otherwise by the Committee at any point following such event:
      (i) neither a temporary absence from employment or service due to illness, vacation or leave of absence (including, without limitation,
      a call to active duty for military service through a Reserve or National Guard unit) nor a transfer from employment or service
      with one Service Recipient to employment or service with another Service Recipient (or vice-versa) shall be considered a Termination;
      and (ii) if a Participant undergoes a Termination of employment, but such Participant continues to provide services to the Company
      and its Affiliates in a non-employee capacity, such change in status shall not be considered a Termination for purposes of the
      Plan. Further, unless otherwise determined by the Committee, in the event that any Service Recipient ceases to be an Affiliate
      of the Company (by reason of sale, divestiture, spin-off or other similar transaction), unless a Participant's employment or service
      is transferred to another entity that would constitute a Service Recipient immediately following such transaction, such Participant
      shall be deemed to have suffered a Termination hereunder as of the date of the consummation of such transaction.

   

  
    19 

    
      

    

  

   

  (i)        No
        Rights as a Stockholder. Except as otherwise specifically provided in the Plan or any Award Agreement, no person shall be
      entitled to the privileges of ownership in respect of shares of Common Stock which are subject to Awards hereunder until such
      shares have been issued or delivered to such person.

   

  (j)
             Government and Other Regulations.

   

  (ii)       The
      obligation of the Company to settle Awards in shares of Common Stock or other consideration shall be subject to all applicable
      laws, rules, and regulations, and to such approvals by governmental agencies as may be required. Notwithstanding any terms or
      conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited
      from offering to sell or selling, any shares of Common Stock pursuant to an Award unless such shares have been properly registered
      for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion
      of counsel (if the Company has requested such an opinion), satisfactory to the Company, that such shares may be offered or sold
      without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been
      fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the shares
      of Common Stock to be offered or sold under the Plan. The Committee shall have the authority to provide that all shares of Common
      Stock or other securities of the Company or any Affiliate issued under the Plan shall be subject to such stop transfer orders
      and other restrictions as the Committee may deem advisable under the Plan, the applicable Award Agreement, the Federal securities
      laws, or the rules, regulations and other requirements of the Securities and Exchange Commission, any securities exchange or inter-dealer
      quotation system on which the securities of the Company are listed or quoted and any other applicable Federal, state, local or
      non-U.S. laws, rules, regulations and other requirements, and, without limiting the generality of Section 9 of the Plan, the Committee
      may cause a legend or legends to be put on certificates representing shares of Common Stock or other securities of the Company
      or any Affiliate issued under the Plan to make appropriate reference to such restrictions or may cause such Common Stock or other
      securities of the Company or any Affiliate issued under the Plan in book-entry form to be held subject to the Company's instructions
      or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the Committee reserves
      the right to add any additional terms or provisions to any Award granted under the Plan that it, in its sole discretion, deems
      necessary or advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction
      the Award is subject.

   

  (iii)       The
      Committee may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions
      and/or blockage and/or other market considerations would make the Company's acquisition of shares of Common Stock from the public
      markets, the Company's issuance of Common Stock to the Participant, the Participant's acquisition of Common Stock from the Company
      and/or the Participant's sale of Common Stock to the public markets, illegal, impracticable or inadvisable. If the Committee determines
      to cancel all or any portion of an Award in accordance with the foregoing, the Company shall pay to the Participant an amount
      equal to the excess of (A) the aggregate Fair Market Value of the shares of Common Stock subject to such Award or portion thereof
      canceled (determined as of the applicable exercise date, or the date that the shares would have been vested or issued, as applicable),
      over (B) the aggregate Exercise Price or Strike Price (in the case of an Option or SAR, respectively) or any amount payable as
      a condition of issuance of shares of Common Stock (in the case of any other Award). Such amount shall be delivered to the Participant
      as soon as practicable following the cancellation of such Award or portion thereof.

  (k)      No
        Section 83(b) Elections Without Consent of Company. No election under Section 83(b) of the Code or under a similar provision
      of law may be made unless expressly permitted by the terms of the applicable Award Agreement or by action of the Committee in
      writing prior to the making of such election. If a Participant, in connection with the acquisition of shares of Common Stock under
      the Plan or otherwise, is expressly permitted to make such election and the Participant makes the election, the Participant shall
      notify the Company of such election within ten (10) days of filing notice of the election with the Internal Revenue Service or
      other governmental authority, in addition to any filing and notification required pursuant to Section 83(b) of the Code or other
      applicable provision.

   

  (l)       Payments
        to Persons Other Than Participants. If the Committee shall find that any person to whom any amount is payable under the Plan
      is unable to care for his or her affairs because of illness or accident, or is a minor, or has died, then any payment due to such
      person or his or her estate (unless a prior claim therefor has been made by a duly appointed legal representative) may, if the
      Committee so directs the Company, be paid to his or her spouse, child, relative, an institution maintaining or having custody
      of such person, or any other person deemed by the Committee to be a proper recipient on behalf of such person otherwise entitled
      to payment. Any such payment shall be a complete discharge of the liability of the Committee and the Company therefor.

   

  (m)     Nonexclusivity
        of the Plan. Neither the adoption of this Plan by the Board nor the submission of this Plan to the stockholders of the Company
      for approval shall be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements
      as it may deem desirable, including, without limitation, the granting of stock options otherwise than under this Plan, and such
      arrangements may be either applicable generally or only in specific cases.

   

  (n)      No
        Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any
      kind or a fiduciary relationship between the Company or any Affiliate, on the one hand, and a Participant or other person or entity,
      on the other hand. No provision of the Plan or any Award 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, except that insofar as they may have become entitled to payment of additional
      compensation by performance of services, they shall have the same rights as other employees under general law.

   

  (o)      Reliance
        on Reports. Each member of the Committee and each member of the Board shall be fully justified in acting or failing to act,
      as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance upon any report made
      by the independent public accountant of the Company and its Affiliates and/or any other information furnished in connection with
      the Plan by any agent of the Company or the Committee or the Board, other than himself.

   

  (p)      Relationship
        to Other Benefits. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement,
      profit sharing, group insurance or other benefit plan of the Company except as otherwise specifically provided in such other plan
      or as required by applicable law.

   

  (q)      Governing
        Law. The Plan shall be governed by and construed in accordance with the internal laws of the State of Delaware applicable
      to contracts made and performed wholly within the State of Delaware, without giving effect to the conflict of laws provisions
      thereof.

   

  (r)       Severability.
      If any provision of the Plan or any Award or Award Agreement is or becomes or is deemed to be invalid, illegal, or unenforceable
      in any jurisdiction or as to any person or entity or Award, or would disqualify the Plan or any Award under any law deemed applicable
      by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed
      or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such
      provision shall be construed or deemed stricken as to such jurisdiction, person or entity or Award and the remainder of the Plan
      and any such Award shall remain in full force and effect.

   

  
    21 

    
      

    

  

   

  (s)       Obligations
        Binding on Successors. The obligations of the Company under the Plan shall be binding upon any successor corporation or organization
      resulting from the merger, consolidation or other reorganization of the Company, or upon any successor corporation or organization
      succeeding to substantially all of the assets and business of the Company.

   

  		(t)	409A of the Code.

   

  (ii)       Notwithstanding
      any provision of the Plan to the contrary, it is intended that the provisions of this Plan comply with Section 409A of the Code,
      and all provisions of this Plan shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes
      or penalties under Section 409A of the Code. Each Participant is solely responsible and liable for the satisfaction of all taxes
      and penalties that may be imposed on or in respect of such Participant in connection with this Plan (including any taxes and penalties
      under Section 409A of the Code), and neither the Company nor any Affiliate shall have any obligation to indemnify or otherwise
      hold such Participant (or any beneficiary) harmless from any or all of such taxes or penalties. With respect to any Award that
      is considered "deferred compensation" subject to Section 409A of the Code, references in the Plan to "termination
      of employment" (and substantially similar phrases) shall mean "separation from service" within the meaning of Section
      409A of the Code. For purposes of Section 409A of the Code, each of the payments that may be made in respect of any Award granted
      under the Plan is designated as separate payments.

   

  (iii)       Notwithstanding
      anything in the Plan to the contrary, if a Participant is a "specified employee" within the meaning of Section 409A(a)(2)(B)(i)
      of the Code, no payments in respect of any Awards that are "deferred compensation" subject to Section 409A of the Code
      and which would otherwise be payable upon the Participant's "separation from service" (as defined in Section 409A of
      the Code) shall be made to such Participant prior to the date that is six months after the date of such Participant's "separation
      from service" or, if earlier, the Participant's date of death. Following any applicable six month delay, all such delayed
      payments will be paid in a single lump sum on the earliest date permitted under Section 409A of the Code that is also a business
      day.

   

  (iv)       Unless
      otherwise provided by the Committee in an Award Agreement or otherwise, in the event that the timing of payments in respect of
      any Award (that would otherwise be considered "deferred compensation" subject to Section 409A of the Code) would be
      accelerated upon the occurrence of (A) a Change in Control, no such acceleration shall be permitted unless the event giving rise
      to the Change in Control (ii) satisfies the definition of a change in the ownership or effective
      control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation pursuant to Section
      409A of the Code and any Treasury Regulations promulgated thereunder or (B) a Disability, no such acceleration shall be permitted
      unless the Disability also satisfies the definition of "Disability" pursuant to Section 409A of the Code and any Treasury
      Regulations promulgated thereunder.

   

  (u)      Clawback/Forfeiture.
      Notwithstanding anything to the contrary contained herein, an Award Agreement may provide that the Committee may, in its sole
      discretion, cancel such Award if the Participant has engaged in or engages in any Detrimental Activity. The Committee may also
      provide in an Award Agreement that if the Participant otherwise has engaged in or engages in any Detrimental Activity, the Participant
      will forfeit any gain realized on the vesting or exercise of such Award, and must repay the gain to the Company. The Committee
      may also provide in an Award Agreement that if the Participant receives any amount in excess of what the Participant should have
      received under the terms of the Award for any reason (including, without limitation, by reason of a financial restatement, mistake
      in calculations or other administrative error), then the Participant shall be required to repay any such excess amount to the
      Company. Without limiting the foregoing, all Awards shall be subject to reduction, cancellation, forfeiture or recoupment to the
      extent necessary to comply with applicable law.

   

  
    22 

    
      

    

  

   

  (v)       Right
        of Offset. The Company will have the right to offset against its obligation to deliver shares of Common Stock (or other property
      or cash) under the Plan or any Award Agreement any outstanding amounts (including, without limitation, travel and entertainment
      or advance account balances, loans, repayment obligations under any Awards, or amounts repayable to the Company pursuant to tax
      equalization, housing, automobile or other employee programs) that the Participant then owes to the Company or an Affiliate, as
      applicable, and any amounts the Committee otherwise deems appropriate pursuant to any tax equalization policy or agreement. Notwithstanding
      the foregoing, if an Award is "deferred compensation" subject to Section 409A of the Code, the Committee will have no
      right to offset against its obligation to deliver shares of Common Stock (or other property or cash) under the Plan or any Award
      Agreement if such offset could subject the Participant to the additional tax imposed under Section 409A of the Code in respect
      of an outstanding Award.

   

  (w)      Expenses;
        Gender; Titles and Headings. The expenses of administering the Plan shall be borne by the Company and its Affiliates. Masculine
      pronouns and other words of masculine gender shall refer to both men and women. The titles and headings of the sections in the
      Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or
      headings, shall control.

   

  (u)      Compliance.
      Notwithstanding any other provision of this Plan, (a) the Company shall not be obliged to issue any Shares pursuant to an Award
      unless at least the nominal value of each such newly issued Share has been fully paid in advance in accordance with applicable
      law (which requirement may mean the holder of an award is obliged to make such payment) and (b) the Company shall not be obliged
      to issue or deliver any Shares in satisfaction of Awards until all legal and regulatory requirements associated with such issue
      or delivery have been complied with to the satisfaction of the Committee.
