Amended and Restated Executive Employment Agreement between the Company and John B. (Thad) Hill, dated August 29, 2018

In consideration of the respective agreements of the parties contained herein, it is agreed as follows:

1.Term. The initial term of this Agreement shall be for the period commencing on the Effective Date and ending, subject to earlier termination as set forth in Section 6, on the fifth (5^th) anniversary of the Effective Date (the “Employment Term”); provided that, on such fifth anniversary of the Effective Date and each annual anniversary thereafter (such date and each annual anniversary thereof, a “Renewal Date”), the Agreement shall be deemed to be automatically extended, upon the same terms and conditions, for successive periods of one year, unless either party provides written notice of its intention not to extend the term of the Agreement at least ninety (90) days’ prior to the applicable Renewal Date.

2.    Employment. During the Employment Term:

(a)    Executive shall be employed as President and Chief Executive Officer of the Company. In addition, as of the Effective Date, Executive shall serve as a member of the board of directors of the Company (the “Board of Directors”). At the time of Executive’s termination of employment with the Company for any reason (the date of such termination, the “Termination Date”), Executive shall resign from the Board of Directors if requested to do so by the Company. Executive shall not receive any additional compensation for serving as a director of the Company or as a director or officer of any of the Company’s subsidiaries.

(b)    Executive shall report directly to the Board of Directors. Executive shall perform the duties, undertake the responsibilities and exercise the authority customarily performed, undertaken and exercised by persons situated in a similar executive capacity. Unless otherwise consented to by Executive, Executive’s principal place of employment shall be at the Company’s headquarters in Houston, Texas.

(c)    Executive shall devote substantially full‑time attention to the business and affairs of the Company. Executive may serve on the boards of directors of other companies, subject

to the approval of the Board of Directors (which approval shall be deemed given in respect of service on boards on which Executive serves as of the Effective Date that are known to the Board of Directors), and may serve on civil or charitable boards or committees. Executive may manage personal and family investments, participate in industry or charitable organizations and otherwise engage in charitable activities and deliver lectures at educational institutions, so long as such activities do not materially interfere with the performance of Executive’s responsibilities hereunder.

3.    Annual Compensation.

(a)    Base Salary. The Company agrees to pay or cause to be paid to Executive during the Employment Term a base salary at the rate of $1,230,000 per annum or such increased amount as the Board of Directors may from time to time determine (hereinafter referred to as the “Base Salary”). Such Base Salary shall be payable in accordance with the Company’s customary practices applicable to its senior executives. Such Base Salary shall be reviewed at least annually by the Board of Directors or, if applicable, the Compensation Committee of the Board of Directors (the “Committee”), and may be increased in the sole discretion of the Board or, if applicable, the Committee, but not decreased (any increased amount thereupon being the Base Salary hereunder).

(b)    Annual Cash Incentive Compensation. For each fiscal year of the Company ending during the Employment Term, beginning with the 2018 fiscal year, Executive shall be eligible to receive a target annual cash bonus of at least 110% of the Base Salary (the “Target Bonus”) with the opportunity to receive a maximum annual cash bonus of at least two times Executive’s Target Bonus or such lesser amount determined by the Board of Directors in connection with a reduction in the maximum bonus amount applicable to all senior executives of the Company (the “Maximum Bonus”), as recommended and approved by the Board of Directors or, if applicable, the Committee, if the Company and Executive, as applicable, achieve reasonable performance targets set by the Board of Directors or, if applicable, the Committee in consultation with Executive in a manner substantially consistent with current practice (“Incentive Compensation”). Incentive Compensation shall be paid in no event later than the 15th day of the third month following the end of the taxable year (of the Company or Executive, whichever is later) in which the performance targets have been achieved.

4.    Class B Interests. On, or as soon as reasonably practicable after the Effective Date, CPN Management, LP, a Delaware limited partnership (the “Partnership”), shall grant to Executive an award of Class B Interests (as defined in the Amended and Restated Limited Partnership Agreement of CPN Management, LP, dated and effective as of March 8, 2018 (as it may be amended, modified or supplemented from time to time, the “LP Agreement”)), which, except as provided in Section 7(c)(iv), shall be governed by the terms and conditions of an award agreement substantially in the form attached hereto as Exhibit A (the “Award Agreement”).

5.    Other Benefits.

(a)    Employee Benefits. During the Employment Term, Executive shall be entitled to participate in all employee benefit plans, practices and programs maintained by the Company and made available to executives and employees generally, including, without limitation, all pension, retirement, profit sharing, savings, medical, hospitalization, disability, dental, life or travel accident insurance benefit plans, to the extent Executive is eligible under the terms of such plans, practices and programs. Executive’s participation in such plans, practices and programs shall be on the same basis and terms as are applicable to senior executives of the Company generally.

(b)    Executive Benefits. During the Employment Term, Executive shall be entitled to participate in all executive benefit and incentive compensation plans now maintained or hereafter established by the Company for the purpose of providing compensation and/or benefits to senior executives of the Company including, but not limited to, the Company’s deferred compensation plans and any supplemental retirement, deferred compensation, supplemental medical or life insurance or other bonus or incentive compensation plans. No additional compensation provided under any of such plans shall be deemed to modify or otherwise affect the terms of this Agreement or any of Executive’s entitlements hereunder.

(c)    Business Expenses. Upon submission of proper invoices in accordance with the Company’s normal procedures, Executive shall be entitled to receive prompt reimbursement of all reasonable out‑of‑pocket business, entertainment and travel expenses incurred by Executive in connection with the performance of Executive’s duties hereunder.

(d)    Office and Facilities. During the Employment Term, Executive shall be provided with an appropriate office at the Company’s headquarters, with such secretarial and other support facilities as are commensurate with Executive’s status with the Company, which facilities shall be adequate for the performance of Executive’s duties hereunder.

(e)    Vacation and Sick Leave. During the Employment Term, Executive shall be entitled to vacation and sick leave (without loss of pay) in accordance with the Company’s policies applicable to senior executives as in effect from time to time.

6.    Termination of Employment. Subject to payment of any compensation due pursuant to Section 7, Executive’s employment with the Company may be terminated by either party during or after the Employment Term upon notice as set forth in Section 8 and this Agreement shall not be construed to alter the at‑will status of Executive’s employment with the Company.

7.    Compensation Upon Termination. Upon termination of Executive’s employment during the Employment Term, Executive shall be entitled to the benefits, if any, described in this Section 7.

(a)    Termination by Executive for Good Reason, by the Company without Cause or a Non‑Renewal of the Agreement Following March 8, 2020 Other than in Connection with a Change in Control. In the event that Executive’s employment with the Company is terminated (I) by Executive for Good Reason, (II) by the Company without Cause during the Employment Term or (III) on account of a non‑renewal of the Agreement by the Company in accordance with Section 1, in each case following March 8, 2020 and other than in the circumstances described in Section 7(e), then, Executive shall be entitled to receive, and the Company shall be obligated to pay to Executive:

(i)    a lump sum payment on the sixtieth (60^th) day following the Termination Date in an amount equal to 2.0 times the sum of (A) Executive’s highest Base Salary in the three years preceding the Termination Date plus (B) Executive’s highest Target Bonus for the year of termination;

(ii)    a lump sum payment equal to (A) all unused vacation time accrued by Executive as of the Termination Date under the Company’s vacation policy; plus (B) all accrued but unpaid compensation earned by Executive as of the Termination Date; plus (C) payment of any Incentive Compensation earned but unpaid in respect of any completed fiscal year preceding the Termination Date (assuming that continued employment by Executive through the payment date is not required pursuant to the terms of the plan or program governing the Incentive Compensation); plus (D) reimbursement for any and all monies advanced or expenses incurred in connection with Executive’s employment for reasonable and necessary expenses incurred by Executive on behalf of the Company in compliance with applicable Company policy for the period ending on the Termination Date; in each case to be paid by the Company as soon as practicable following the Termination Date but no later than sixty (60) days after the Termination Date ((A), (B) (C) and (D), together referred to herein as the “Accrued Obligations”);

(iii)    an amount equal to the annual cash Incentive Compensation Executive would have been entitled to receive in respect of the fiscal year in which the Termination Date occurs had Executive continued in employment until the end of such fiscal year, which amount shall be determined based on actual performance for such year relative to the performance goals applicable to Executive, with the amount of such bonus being multiplied by a fraction (A) the numerator of which is the number of days in such fiscal year through the Termination Date and (B) the denominator of which is 365 (the “Pro‑rata Bonus”), which shall be payable at such time as the Company pays annual bonuses for the year in which the Termination Date occurs, but in no event later than the 15th day of the third month following the end of the taxable year (of the Company or Executive, whichever is later) in which the performance targets have been achieved;

(iv)    prompt reimbursement by the Company for outplacement benefits actually paid for by Executive after the Termination Date and before the twenty four (24) month anniversary of the Termination Date after timely presentation of appropriate documentation of such

expense by Executive to the Company, such reimbursement to be paid in accordance with Section 11 of this Agreement; and

(v)    a monthly payment for a period of twenty‑four (24) months following the Termination Date, paid pursuant to the Company’s payroll practices in effect at such time, equal to (a) the full monthly premium paid by other former employees of the Company for continuation coverage under the Company’s health plans in which the Executive and his dependents participated immediately prior to his Termination Date, plus (b) such additional amounts as are necessary to ensure receipt by the Executive of the full amount described in (a) after application of all federal income (assuming the maximum federal income tax rate) and employment taxes imposed upon the amount described in (a) (each monthly payment that is the sum of (a) and (b), an “Additional Payment”).

For purposes of this Agreement, “Good Reason” means any of the following, in each case only if it occurs when Executive is employed by the Company and then only if not consented to by Executive in writing: (A) assignment of a position that is of a lesser rank than that held by Executive prior to the assignment and that results in Executive ceasing to be President and Chief Executive Officer of the Company; (B) a material diminution of Executive’s duties or responsibilities; (C) the assignment of duties inconsistent with Executive’s title or responsibilities; (D) failure by the Company to nominate Executive for election as a member of the Board of Directors and use its best efforts to have him elected and re‑elected; (E) failure to cause a successor to the Company’s business or substantially all of the Company’s assets to assume this Agreement; (F) a material reduction in Executive’s Base Salary or Target Bonus (including a material adverse change in performance criteria or a material decrease in ultimate Target Bonus opportunity); or (G) any change of more than thirty (30) miles in the location of the principal place of employment of Executive immediately prior to the effective date of such change. For purposes of this definition, none of the actions described in clauses (A), (B) and (C) above shall constitute “Good Reason” with respect to Executive if it was an isolated and inadvertent action not taken in bad faith by the Company and if it is remedied by the Company within thirty (30) days after receipt of written notice thereof given by Executive (or, if the matter is not capable of remedy within thirty (30) days, then within a reasonable period of time following such thirty (30) day period, provided that the Company has commenced such remedy within said thirty (30) day period); provided that “Good Reason” shall cease to exist for any action described in clauses (A) through (F) above on the sixtieth (60th) day following the later of the occurrence of such action or Executive’s knowledge thereof, unless such Executive has given the Company written notice thereof prior to such date.

For purposes of this Agreement, “Cause” shall mean:(A) Executive’s act of fraud, dishonesty, misappropriation, or embezzlement with respect to the Company; (B) Executive’s conviction of, or plea of guilty or no contest to, any felony; (C) Executive’s violation of the Company’s drug policy or anti‑harassment policy; (D) Executive’s admission of liability of, or finding by a court or the U.S. Securities and Exchange Commission (or a similar agency of any applicable state) of liability for, the violation of any Federal or state law, rule or regulation governing the issuance or exchange of securities, including without limitation the Securities Act of 1933, as amended, the

Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder (collectively, the “Securities Laws”) (excluding any technical violations of the Securities Laws which are not criminal in nature); (E) Executive’s failure after reasonable prior written notice from the Company to comply with any valid and legal directive of the Board of Directors that is not remedied within thirty (30) days of Executive being provided written notice thereof from the Company or Executive’s gross negligence in performance, or willful nonperformance, of any of Executive’s duties and responsibilities with respect to the Company that is not remedied within thirty (30) days of Executive being provided written notice thereof from the Company; or (F) other than as provided in clauses (A) through (C) above, Executive’s material breach of any material provision of this Agreement that is not remedied within thirty (30) days of Executive being provided written notice thereof. Executive shall not have acted in a “willful” manner if Executive acted, or failed to act, in a manner that he believed in good faith to be in, or not opposed to, the best interests of the Company.

(b)    Disability or Death. If Executive experiences a Disability (as defined below) or death during the Employment Term, Executive shall be entitled to receive:

(i)    payment of the Accrued Obligations as soon as practicable following the date that the Board of Directors determines that Executive has a Disability or the date of Executive’s death (each a “DD Event Date”) but no later than sixty (60) days thereafter;

(ii)    payment of an amount equal to the Incentive Compensation that Executive would have been entitled to receive in respect of the fiscal year in which the DD Event Date occurs, had Executive continued in employment until the end of such fiscal year, which amount shall be determined based on the Company’s actual performance for such year relative to the target performance goals applicable to Executive and shall be paid at such time as the Company pays annual bonuses for the year in which the DD Event Date occurs, but in no event later than the 15th day of the third month following the end of the taxable year (of the Company or Executive, whichever is later) in which the performance targets have been achieved; and

(iii)    payment of the Additional Payment on a monthly basis for a period of eighteen (18) months following the DD Event Date, paid pursuant to the Company’s payroll practices in effect at such time.

For purposes of this Agreement, Executive will be deemed to have a “Disability” if, as a result of any medically determinable physical or mental impairment that can be expected to result in death or is reasonably expected to last for a continuous period of not less than twelve (12) months, Executive is unable to perform the core functions of Executive’s position (with or without reasonable accommodation) for a period of six (6) consecutive months or more, or is receiving income replacement benefits, for a period of six (6) consecutive months or more under an accident and health plan covering employees of the Company. As a general matter, Executive shall be entitled to the compensation and benefits provided for under this Agreement for any period prior to the DD

Event Date during which Executive is unable to work due to a physical or mental infirmity in accordance with the Company’s policies for similarly‑situated executives. If any question shall arise as to whether, during any period Executive is disabled so as to be unable to perform the core functions of Executive’s then existing position with or without reasonable accommodation, Executive may, and at the request of the Company shall, submit to the Company a certification in reasonable detail by a physician selected by the Company, to whom Executive or Executive’s guardian has no reasonable objection, as to whether Executive is so disabled and how long such disability is expected to continue, and such certification shall for the purposes of this Agreement be conclusive of the issue. Executive shall cooperate with any reasonable request of the physician in connection with such certification. If such question shall arise and Executive shall fail to submit such certification, the Company’s determination of such issue shall be binding on Executive. Nothing in this Agreement shall be construed to waive Executive’s rights, if any, under existing law including, without limitation, the Family and Medical Leave Act of 1933, 29 U.S.C. ss.2601 et seq. and the Americans With Disabilities Act, 424 S.C. ss.12101 et seq.

Notwithstanding the foregoing, for purposes of an award or element of compensation that provides for a deferral of compensation under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations and guidance issued thereunder, to the extent the impact of a Disability on such compensation would subject Executive to additional taxes under Code Section 409A, a Disability for purposes of such compensation will mean both a Disability and a “disability” within the meaning of Treasury Regulation 1.409A‑3(i)(4).

(c)    Retirement. If Executive’s employment terminates for any reason following the fifth (5^th) anniversary of the Effective Date, Executive shall be entitled to the following benefits, without duplication of any other amounts payable pursuant to this Section 7:

(i)    payment of the Accrued Obligations;

(ii)    payment of the Pro‑Rata Bonus, which shall be payable at such time as the Company pays annual bonuses for the year in which the Termination Date occurs, but in no event later than the 15th day of the third month following the end of the taxable year (of the Company or Executive, whichever is later) in which the performance targets have been achieved;

(iii)    payment of the Additional Payment on a monthly basis for a period of for twenty-four (24) months following the Termination Date, paid pursuant to the Company’s payroll practices in effect at such time;

(iv)    upon Executive’s election, the Partnership and/or the Company’s exercise of the Partnership Redemption Right (as defined in the LP Agreement) and/or the Calpine Repurchase Right (as defined in the LP Agreement), respectively, and/or any other applicable call right in favor of the Partnership and/or the Company that may be applicable to vested Class B Interests under the plans, documents and agreements governing such interests shall be subject to the Executive’s consent, which may be withheld in Executive’s absolute discretion.

(d)    Termination by Executive for Good Reason or by the Company without Cause On or Prior to March 8, 2020 Other Than in Connection with a Change in Control. In the event that during the Employment Term and on or prior to March 8, 2020, Executive’s employment with the Company is terminated (A) by Executive for Good Reason or (B) by the Company without Cause, in each case other than in the circumstances described in Section 7(e), then Executive shall be entitled to receive, and the Company shall be obligated to pay to Executive:

(i)    a lump sum payment on the sixtieth (60th) day following the Termination Date in an amount equal to 3.0 times the sum of (A) Executive’s highest Base Salary in the three years preceding the Termination Date plus (B) Executive’s highest Target Bonus for the year of termination or for 2018, whichever is larger; and

(ii)    payment of all Accrued Obligations as soon as practicable following the Termination Date but no later than sixty (60) days after the Termination Date; and

(iii)    the Pro‑rata Bonus, which shall be payable at such time as the Company pays annual bonuses for the year in which the Termination Date occurs, but in no event later than the 15th day of the third month following the end of the taxable year (of the Company or Executive, whichever is later) in which the performance targets have been achieved; and

(iv)    prompt reimbursement by the Company for outplacement benefits actually paid for by Executive after the Termination Date and before the twenty four (24) month anniversary of the Termination Date after timely presentation of appropriate documentation of such expense by Executive to the Company, such reimbursement to be paid in accordance with Section 11 of this Agreement; and

(v)    payment of the Additional Payment on a monthly basis for a period of thirty‑six (36) months following the Termination Date, paid pursuant to the Company’s payroll practices in effect at such time.

(e)    Termination by Executive for Good Reason, by the Company without Cause or a Non‑Renewal of the Agreement in Connection with a Change in Control. In the event that Executive’s employment with the Company is terminated (I) by Executive for Good Reason, (II) by the Company without Cause during the Employment Term or (III) on account of a non‑renewal of the Agreement by the Company in accordance with Section 1, in each case within twenty‑four (24) months following a Change in Control that occurs following the date of this Agreement or within nine (9) months prior to a Change in Control that occurs following the date of this Agreement, then in lieu of the amounts due under Section 7(a) or Section 7(d) above, Executive shall be entitled to receive, and the Company shall be obligated to pay to Executive:

(i)    a lump sum payment on the sixtieth (60^th) day following the Termination Date in an amount equal to 3.0 times the sum of (A) Executive’s highest Base Salary

in the three years preceding the Termination Date plus (B) Executive’s highest Target Bonus for the year of termination or for the year in which the Change in Control occurred, whichever is larger (the amount of such lump sum payment, the “CIC Severance”); provided that if Executive is terminated within nine (9) months prior to a Change in Control under the circumstances described in this Section 7(e), the Company shall pay to Executive a lump sum payment on the sixtieth (60^th) day following such Change in Control in an amount equal to the excess of (y) the CIC Severance over (z) the amount the Company previously paid to Executive pursuant to Section 7(a) or Section 7(d), as applicable;

(ii)    payment of all Accrued Obligations as soon as practicable following the Termination Date but no later than sixty (60) days after the Termination Date;

(iii)    the Pro‑rata Bonus, which shall be payable at such time as the Company pays annual bonuses for the year in which the Termination Date occurs, but in no event later than the 15th day of the third month following the end of the taxable year (of the Company or Executive, whichever is later) in which the performance targets have been achieved;

(iv)    prompt reimbursement by the Company for outplacement benefits actually paid for by Executive after the Termination Date and before the twenty four (24) month anniversary of the Termination Date after timely presentation of appropriate documentation of such expense by Executive to the Company, such reimbursement to be paid in accordance with Section 11 of this Agreement; and

(v)    payment of the Additional Payment on a monthly basis for a period of thirty‑six (36) months following the Termination Date, paid pursuant to the Company’s payroll practices in effect at such time.

For purposes of this Agreement, “Change in Control” shall be defined as in the Award Agreement.

Notwithstanding the foregoing, for purposes of an award or element of compensation that provides for a deferral of compensation under Code Section 409A and the regulations and guidance issued thereunder, to the extent the impact of a Change in Control on such compensation would subject Executive to additional taxes under Code Section 409A, a Change in Control for purposes of such compensation will mean both a Change in Control and a “change in the ownership of a corporation,” “change in the effective control of a corporation,” or a “change in the ownership of a substantial portion of a corporation’s assets” within the meaning of Code Section 409A, as applied to the Company.

(f)    Other Terminations. If Executive’s employment is terminated in a manner other than would give rise to the payment of compensation or benefits pursuant to Section 7(a), Section 7(b), Section 7(c), Section 7(d) or Section 7(e) Executive shall only be entitled under this Agreement to receive the Accrued Obligations, which shall be payable as soon as practicable following the Termination Date but no later than sixty (60) days after the Termination Date.

(g)    No Other Severance or change in control Payments. This Section 7 outlines the only payment or benefit obligations of the Company to the Executive in the event of a termination of employment or change in control. Any amounts payable under this Agreement shall be in lieu of and not in addition to any other severance, termination, or change in control payments under any other agreement or plan with the Company. For the avoidance of doubt, Executive will not be entitled to any payment or benefit under the Calpine Corporation Change in Control and Severance Benefits Plan, as amended from time to time (the “Severance Plan”).

(h)    No Mitigation. Executive shall not be required to mitigate the amount of any payment provided for under this Section 7 by seeking other employment or otherwise and, except as provided in Section 7(a)(v), Section 7(d)(v) or Section 7(e)(v) above, no such payment shall be offset or reduced by the amount of any compensation or benefits provided to Executive in any subsequent employment.

8.    Termination Notice.

(a)    Any purported termination by the Company or by Executive shall be communicated by written Termination Notice to the other party hereto, which shall be delivered in the period proscribed above in Section 7 with respect to such form of termination or, if no such period is proscribed in Section 7, at least thirty (30) days prior to the Termination Date, except in the case of a termination by the Company for Cause, which shall require no advanced notice. For purposes of this Agreement, a “Termination Notice” shall mean a notice that indicates a Termination Date and otherwise meets the requirements set forth with respect to a Termination Notice in Section 7, above, and Section 8(b) and Section 8(c), below. For purposes of this Agreement, no such purported termination of Executive’s employment hereunder shall be effective without such Termination Notice (unless waived by the party entitled to receive such notice).

(b)    For purposes of this Agreement, in order for Executive to terminate his employment for Good Reason, he must give a Termination Notice to the Company, which notice shall be signed by Executive, shall be dated the date it is given to the Company, shall specify the Termination Date and shall state that the termination is for Good Reason and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for such Good Reason. Any Termination Notice given by Executive that does not comply in all material respects with the foregoing requirements as well as the “Good Reason” definition provisions set forth in this Agreement shall be invalid and ineffective for purposes of this Agreement. If the Company receives from Executive a Termination Notice that it believes is invalid and ineffective as aforesaid, it shall promptly notify Executive of such belief and the reasons therefor. Any termination of employment by Executive that either does not constitute Good Reason or fails to meet the Termination Notice requirements set forth above shall be deemed a termination by Executive without Good Reason.

(c)    For purposes of this Agreement, in order for the Company to terminate Executive’s employment for Cause, the Company must give a Termination Notice to Executive, which notice shall be dated the date it is given to Executive, shall specify the Termination Date and shall state that the termination is for Cause and shall set forth in reasonable detail the particulars thereof. For purposes of this Agreement, in order for the Company to terminate Executive’s employment without Cause, the Company must give a Termination Notice to Executive, which notice shall be dated the date it is given to Executive, shall specify the Termination Date and shall state that the termination is without Cause. For purposes of this Agreement, in order for the Company to terminate Executive’s employment for Disability, the Company must give a Termination Notice to Executive, which notice shall be dated the date it is given to Executive, shall specify the Termination Date and shall state that the termination is for Disability and shall set forth in reasonable detail the particulars thereof. Any Termination Notice given by the Company that does not comply, in all material respects, with the foregoing requirements shall be invalid and ineffective for purposes of this Agreement. No Termination Notice must be provided in the event of a termination of Executive’s employment by reason of death. Any Termination Notice purported to be given by the Company to Executive after the death or retirement of Executive shall be invalid and ineffective.

9.    Affirmation of Restrictive Covenants. In entering into this Agreement, Executive expressly acknowledges and agrees that he is bound by those restrictions set forth in that certain Restrictive Covenant Agreement (the “Restrictive Covenant Agreement”) dated as of September 1, 2008, by and between Executive and the Company, which such restrictions Executive acknowledges and agrees are reasonable and enforceable in all respects. Employee expressly covenants to abide by the covenants set forth in the Restrictive Covenant Agreement, which such provisions are herein incorporated by reference; provided that the last sentences of each of Section 2(a) and Section 2(b) of the Restrictive Covenant Agreement (providing that the provisions of such Sections shall not apply following a termination of Executive’s employment that occurs on or after a Change in Control (as defined in the Restrictive Covenant Agreement)), are hereby deleted and shall have no further force or effect.

10.    Clawback. To the extent required by applicable law, including, without limitation, the requirements of the Dodd‑Frank Wall Street Reform and Consumer Protection Act of 2010, any Securities Exchange Commission rule or any applicable securities exchange listing standards, amounts paid or payable pursuant to this Agreement shall be subject to clawback to the extent necessary to comply with such law(s), which clawback may include forfeiture, repurchase and/or recoupment of amounts paid or payable hereunder.

11.    Section 409A. To the extent applicable, it is intended that this Agreement comply with the provisions of Code Section 409A and this Agreement will be administered and interpreted in a manner consistent with this intent. Notwithstanding anything contained herein to the contrary, for all purposes of this Agreement, Executive shall not be deemed to have had a termination of employment unless Executive has incurred a separation from service from the Company within the meaning of Code Section 409A and, to the extent required to avoid accelerated taxation and/or tax penalties under Code Section 409A, payments under this Agreement that would otherwise be payable

during the six‑month period after the Termination Date shall instead be paid on the first business day after the expiration of such six‑month period. In addition, for purposes of this Agreement, each amount to be paid and each installment payment shall be construed as a separate identified payment for purposes of Code Section 409A. With respect to expenses eligible for reimbursement under the terms of this Agreement, (a) the amount of such expenses eligible for reimbursement in any taxable year shall not affect the expenses eligible for reimbursement in another taxable year, (b) any reimbursements of such expenses shall be made no later than the end of the calendar year following the calendar year in which the related expenses were incurred, and (c) the right to reimbursement or in‑kind benefits is not subject to liquidation or exchange for another benefit, except, in each case, to the extent that the right to reimbursement does not provide for a “deferral of compensation” within the meaning of Code Section 409A.

12.    Section 280G.

(a)    The Company shall pay to or for the benefit of Executive, at the time specified in this Section 12(a), an additional amount (the “Gross‑up Payment”) such that the net after‑tax amount of the Gross‑Up Payment retained by Executive, after deduction of any Excise Tax (as defined below) and any federal and state and local taxes imposed on the Gross‑Up Payment itself, shall be equal to the Excise Tax imposed on the 280G Payments (as defined below) if:

(i)    there is a change in the ownership of the Company, a change in the effective control of the Company or a change in the ownership of a substantial portion of the assets of the Company (in each case, within the meaning of Section 280G of the Code and the regulations thereunder);

(ii)    immediately before the change described in Section 12(a)(i), the stock in the Company was readily tradeable on an established securities market or otherwise (within the meaning of Section 280G of the Code and the regulations thereunder); and

(iii)    it is determined that any payments, rights or benefits, or the lapse or termination of any restriction, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement of Executive with the Company or with any person affiliated with the Company, or with any person who acquires ownership or effective control or ownership of a substantial portion of the Company’s assets (within the meaning of Section 280G of the Code and the regulations thereunder) or with any affiliate of such person, and whether or not Executive’s employment has then terminated (collectively, the “280G Payments”), would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest and penalties, are collectively referred to as the “Excise Tax”).

The Gross‑Up Payment shall be paid to or for the benefit of Executive no later than fifteen (15) business days prior to the date by which Executive is required to pay the Excise Tax or

any portion thereof to any federal, state or local taxing authority, without regard to extensions, subject to the terms of this Section 12.

(b)    For purposes of determining the amount of the Gross‑Up Payment, Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation in the calendar year in which the Gross‑Up Payment is to be made and state and local income taxes at the highest marginal rate of taxation in the state and locality of Executive’s residence in the calendar year in which the Gross‑Up Payment is made, net of the maximum reduction in federal income taxes, if any, which could be obtained from deduction of such state and local taxes. For the avoidance of doubt, the intent of the Gross‑Up Payment is solely to make the imposition of the Excise Tax tax‑neutral for Executive.

(c)    Subject to any determinations made by the Internal Revenue Service (the “IRS”), all determinations required to be made under this Section 12 relating to the Gross‑Up Payment, including whether and when a Gross‑Up Payment is required and the amount of such Gross‑Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by a nationally recognized certified public accounting firm or a consulting firm as may be designated by the Company and that is not serving as accountant or auditor for the Company or the individual, entity or group effecting the Change in Control (the “Accountants”), which shall provide detailed supporting calculations both to the Company and Executive. All fees and expenses of the Accountants will be borne by the Company. Subject to any determinations made by the IRS, determinations of the Accountants under this Agreement with respect to (i) the initial amount of any Gross‑Up Payment and (ii) any subsequent adjustment of such payment shall be binding on the Company and Executive.

(d)    In the event that the Excise Tax is subsequently determined to be less than the amount taken into account hereunder, Executive shall repay to the Company at the time that the amount of such reduction in Excise Tax is finally determined, the portion of the Gross‑Up Payment attributable to such reduction, with the amount of such repayment determined by the Accountants; provided, however, that if the Company determines that such repayment obligation would be or result in an unlawful extension of credit under Section 13(k) of the Exchange Act, repayment shall not be required. In the event that the Excise Tax is determined by the Accountants to exceed the amount taken into account hereunder (including by reason of any payment the existence or amount of which cannot be determined at the time of the Gross‑Up Payment), the Company shall make an additional Gross‑Up Payment in respect of such excess (plus any interest and penalties payable with respect to such excess) at the time that the amount of such excess is finally determined.

(e)    Executive shall notify the Company of any audit or review by the IRS of Executive’s federal income tax return for the year in which a payment under this Agreement is made within ten (10) days of Executive’s receipt of notification of such audit or review. Executive shall not pay any IRS claim resulting from any such audit or review prior to the expiration of the thirty

(30)‑day period following the date on which he gives notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies Executive in writing prior to the expiration of such period that it desires to contest such claim, Executive shall:

(i)    give the Company any information reasonably requested by the Company relating to such claim;

(ii)    take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company;

(iii)    cooperate with the Company in good faith in order to effectively contest such claim; and

(iv)    permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold Executive harmless, on an after‑tax basis, for any Excise Tax or federal, state and local income and employment tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 12, the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct Executive to pay the tax claimed and sue for a refund or to contest the claim in any permissible manner, and Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to Executive, on an after‑tax basis, and shall hold Executive harmless from any Excise Tax or federal, state or local income or employment tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of Executive with respect to with such contested amount is claimed to be due is limited solely to such contested amount. The Company’s control of the contest, however, shall be limited to issues with respect to which a Gross‑Up Payment would be payable hereunder, and Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the IRS or any other taxing authority. If, after the receipt by Executive of an amount advanced by the Company pursuant to this Section 12(e), Executive becomes entitled to receive any refund with respect to such claim, Executive shall (subject to the Company’s complying with

the requirements of this Section 12(e)) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto); provided, however, that if the Company determines that such repayment obligation would be or result in an unlawful extension of credit under Section 13(k) of the Exchange Act, repayment shall not be required. If, after receipt by Executive of an amount advanced by the Company pursuant to this Section 12(e), a determination is made that the Executive shall not be entitled to any refund with respect to any such claim and the Company does not notify Executive in writing of its intent to contest such denial of refund prior to the expiration of thirty (30) days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross‑Up Payment required to be paid.

(f)    If, other than in the circumstances described in Section 12(a), it is determined that any of the 280G Payments would be subject to the Excise Tax, then, to the extent necessary to make such portion of the 280G Payments not subject to the Excise Tax (and after taking into account any reduction in the 280G Payments provided by reason of Section 280G of the Code under any other plan, arrangement or agreement), the portion of the 280G Payments that do not constitute deferred compensation within the meaning of Section 409A shall first be reduced (if necessary, to zero), and all other 280G Payments shall thereafter be reduced (if necessary, to zero) with cash payments being reduced before noncash payments, and payments to be paid last being reduced first, but only if (i) the net amount of such 280G Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced 280G Payments and after taking into account any phase out of itemized deductions and personal exemptions attributable to such reduced 280G Payments) is greater than or equal to (ii) the net amount of such 280G Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such 280G Payments and the amount of Excise Tax to which Executive would be subject in respect of such unreduced 280G Payments and after taking into account any phase out of itemized deductions and personal exemptions attributable to such unreduced 280G Payments).

Such indemnification shall continue as to Executive even if he has ceased to be a director, officer, member, employee, agent, manager, trustee, consultant or representative of the Company and shall inure to the benefit of his heirs, executors and administrators. Executive shall be entitled to prompt advancement of any and all costs and expenses (including, without limitation, attorneys’ and other professional fees and charges) reasonably incurred by him in connection with any such Proceeding, any such advancement to be made within 15 days after Executive gives written notice, supported by reasonable documentation, requesting such advancement. Such notice shall include an undertaking by Executive to repay the amounts advanced to the extent that he is ultimately determined not to be entitled to indemnification against such costs and expenses. Nothing in this Agreement or elsewhere shall operate to limit or extinguish any right to indemnification, advancement of expenses, or contribution that Executive would otherwise have (including, without limitation, by agreement or under applicable law). Executive shall be covered during the Employment Term and thereafter for as long as any executive is covered (but in no event for less than six (6) years) by officer and director liability insurance, in amounts and on terms no less favorable than those in effect on the Effective Date, which insurance shall be paid by the Company.
