other equity plan subsequently adopted by the Company) granted to Executive after the Effective Date shall vest in full. 
 2. If Executive’s employment is terminated by the Company without Cause (and other than by reason of Poor Performance or Executive’s death or Disability) or if Executive resigns for Good Reason

the Company’s group health plan, continued for the lesser of (i) eighteen (18) months from the date of termination of Executive’s employment or (ii) the date on which Executive qualifies for health insurance as a result of
employment by or association with a subsequent employer;

V.E of this Agreement shall be grossed-up by the Company to cover (1) any federal excise tax due by that Executive on account of these benefit payments and (2) any federal income and employment taxes due on federal excise tax. 

h. Notwithstanding anything in this Agreement to the contrary, if Executive is a “disqualified individual” (as
defined in Section 280G(c) of the Code), and the payments and benefits provided for in this Section IV.C of this Agreement, together with any other payments and benefits which Executive has the right to receive from the Company or any other
person, would constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), then the payments and benefits provided for in this Agreement shall be either (a) reduced (but not below zero) so that the present
value of such total amounts and benefits received by Executive from the Company and/or such person(s) will be $1.00 less than three (3) times Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code) and so
that no portion of such amounts and benefits received by Executive shall be subject to the excise tax imposed by Section 4999 of the Code or (b) paid in full, whichever produces the better “net after-tax position” to Executive
(taking into account any applicable excise tax under Section 4999 of the Code and any other applicable

taxes). The reduction of payments and benefits hereunder, if applicable, shall be made by reducing, first, payments or benefits to be paid in cash hereunder in the order in which such payment or
benefit would be paid or provided (beginning with such payment or benefit that would be made last in time and continuing, to the extent necessary, through to such payment or benefit that would be made first in time) and, then, reducing any benefit
to be provided in-kind hereunder in a similar order. The determination as to whether any such reduction in the amount of the payments and benefits provided hereunder is necessary shall be made by the Company in good faith. If a reduced payment or
benefit is made or provided and through error or otherwise that payment or benefit, when aggregated with other payments and benefits from the Company (or its affiliates) used in determining if a “parachute payment” exists, exceeds $1.00
less than three (3) times Executive’s base amount, then Executive shall immediately repay such excess to the Company upon notification that an overpayment has been made. Nothing in this paragraph shall require the Company to be responsible

termination.

writing, by the Compensation Committee of the Board, in its sole discretion, the Company shall not make or provide, and Executive shall not be entitled to receive, any severance payments or benefits provided under this Agreement, other than the

obligations to make and provide the severance payments and benefits as provided in this Agreement and (y) any vested benefits to which Executive is entitled under the terms of any Company benefit or equity plan, and (ii) Executive does not
revoke such release within any applicable revocation period following Executive’s delivery of the executed release to the Company. If the requirements of this Section are satisfied, then the severance payments and benefits which Executive is

employee,” as defined in Section 409A of the Code, and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to avoid

  
 10 

 
the additional tax under Section 409A of the Code, then the Company will defer the payment or the commencement of any such payments or benefits hereunder (without any reduction in such
payments or benefits ultimately paid or provided to Executive) until the date that is six months following Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A of the Code). Any

by the Company in no event later than the close of Executive’s taxable year following the taxable year in which the cost or expense is incurred by Executive. The expenses incurred by Executive in any calendar year that are eligible for
reimbursement under this Agreement shall not affect the expenses incurred by Executive in any other calendar year that are eligible for reimbursement hereunder and Executive’s right to receive any reimbursement hereunder shall not be subject to
liquidation or exchange for any other benefit. 
 3. Each payment that Executive may receive under this Agreement
shall be treated as a “separate payment” for purposes of Section 409A of the Code. 
 4. Except as provided in V.I.1, and notwithstanding anything in this Agreement to the contrary, the payment of an Annual Bonus, Performance Award, cash incentive award or equity-based award due thereunder
shall be paid in all events within 2 1/2 months
after the end of the year in which such award (or prorated part) first becomes “vested,” within the meaning of Section 409A of the Code. 
 5. To the extent that Section 409A of the Code applies to any terms or conditions of this Agreement, such terms and conditions shall be interpreted in a manner that is consistent with
Section 409A of the Code.

and to such maximum extent as such court may judicially determine or indicate to be enforceable. Alternatively, if any court of competent jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction

other equity plan subsequently adopted by the Company) granted to Executive after the Effective Date shall vest in full. 
 2. If Executive’s employment is terminated by the Company without Cause (and other than by reason of Poor Performance or Executive’s death or Disability) or if Executive resigns for Good Reason

defined in Section 280G(c) of the Code), and the payments and benefits provided for in this Section IV.C of this Agreement, together with any other payments and benefits which Executive has the right to receive from the Company or any other
person, would constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), then the payments and benefits provided for in this Agreement shall be either (a) reduced (but not below zero) so that the present
value of such total amounts and benefits received by Executive from the Company and/or such person(s) will be $1.00 less than three (3) times Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code) and so
that no portion of such amounts and benefits received by Executive shall be subject to the excise tax imposed by Section 4999 of the Code or (b) paid in full, whichever produces the better “net after-tax position” to Executive

taxes). The reduction of payments and benefits hereunder, if applicable, shall be made by reducing, first, payments or benefits to be paid in cash hereunder in the order in which such payment or
benefit would be paid or provided (beginning with such payment or benefit that would be made last in time and continuing, to the extent necessary, through to such payment or benefit that would be made first in time) and, then, reducing any benefit

benefit is made or provided and through error or otherwise that payment or benefit, when aggregated with other payments and benefits from the Company (or its affiliates) used in determining if a “parachute payment” exists, exceeds $1.00
less than three (3) times Executive’s base amount, then Executive shall immediately repay such excess to the Company upon notification that an overpayment has been made. Nothing in this paragraph shall require the Company to be responsible

obligations to make and provide the severance payments and benefits as provided in this Agreement and (y) any vested benefits to which Executive is entitled under the terms of any Company benefit or equity plan, and (ii) Executive does not
revoke such release within any applicable revocation period following Executive’s delivery of the executed release to the Company. If the requirements of this Section are satisfied, then the severance payments and benefits which Executive is
otherwise entitled to receive under this Agreement shall begin or be made, as applicable, without interest, on the later of (i) the sixtieth (60th) day following the date on which Executive’s employment was terminated or (ii) on

employee,” as defined in Section 409A of the Code, and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to avoid

  
 10 

 
the additional tax under Section 409A of the Code, then the Company will defer the payment or the commencement of any such payments or benefits hereunder (without any reduction in such
payments or benefits ultimately paid or provided to Executive) until the date that is six months following Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A of the Code). Any
payment amounts deferred pursuant to this Section will be accumulated and paid to Executive (without interest) in a lump sum and the balance of any remaining payments due Executive will be paid monthly or at such times as otherwise provided herein.

 2. Any reimbursement of any costs and expenses by the Company to Executive under this Agreement shall be made
by the Company in no event later than the close of Executive’s taxable year following the taxable year in which the cost or expense is incurred by Executive. The expenses incurred by Executive in any calendar year that are eligible for
reimbursement under this Agreement shall not affect the expenses incurred by Executive in any other calendar year that are eligible for reimbursement hereunder and Executive’s right to receive any reimbursement hereunder shall not be subject to
liquidation or exchange for any other benefit. 
 3. Each payment that Executive may receive under this Agreement
shall be treated as a “separate payment” for purposes of Section 409A of the Code. 
 4. Except as provided in V.I.1, and notwithstanding anything in this Agreement to the contrary, the payment of an Annual Bonus, Performance Award, cash incentive award or equity-based award due thereunder
shall be paid in all events within 2 1/2 months
after the end of the year in which such award (or prorated part) first becomes “vested,” within the meaning of Section 409A of the Code. 
 5. To the extent that Section 409A of the Code applies to any terms or conditions of this Agreement, such terms and conditions shall be interpreted in a manner that is consistent with
Section 409A of the Code.

any of the provisions of this Agreement or the Confidentiality Agreement, the Company shall be entitled to recover, and the Executive (or his estate) shall be obligated to repay and return to the Company, upon written demand therefore, an amount
