4.Termination.

The Executive’s employment hereunder may be terminated by the Company or the Executive, as applicable, without any breach of this Agreement only under the following circumstances:

(a)Circumstances

(i)Death. The Executive’s employment hereunder shall terminate upon the Executive’s death.

(ii)Disability. If the Executive incurs a Disability, the Company may give the Executive written notice of its intention to terminate the Executive’s employment. In that event, the Executive’s employment with the Company shall terminate, effective on the later of the thirtieth (30th) day after receipt of such notice by the Executive or the date specified in such notice; provided that Executive’s Disability continues beyond such thirty (30) day notice period.

(iii)Termination for Cause. The Company may terminate the Executive’s employment for Cause. Executive’s termination will not be deemed to be for Cause unless the Company has provided a written Notice of Termination (defined in Section 4(b) below) to Executive specifying the event or condition claimed to constitute Cause and, in the case of a termination pursuant to Section 1(h)(i), (ii), or (vi), Executive has failed to cure Executive’s failure or breach within thirty (30) days following the Executive’s receipt of the Company’s Notice of Termination (to the extent that, in the reasonable judgment of the Board, such failure or breach can be cured by the Executive).

(iv)Termination without Cause. The Company may terminate the Executive’s employment without Cause.

(v)Resignation for Good Reason. The Executive may resign from employment for Good Reason. Executive’s resignation will not be deemed to be for Good Reason if Executive has consented to the condition claimed to constitute Good Reason, nor will Executive’s resignation be deemed to be for Good Reason, unless Executive has provided a written Notice of Termination (defined in Section 4(b) below) to the Company specifying the event or condition claimed to constitute Good Reason within ninety (90) days following the initial existence of such event or condition, and the Company has, after receipt of such notice of Good Reason from Executive, failed to cure or correct such condition or event within thirty (30) days following the Company’s receipt of Executive’s Notice of Termination evidencing intent to resign for Good Reason.

(vi)Resignation without Good Reason. The Executive may resign from the Executive’s employment without Good Reason.

(vii)Non-Extension of Term by the Company. The Company may give notice of non-extension to the Executive pursuant to Section 2(b). For the avoidance of doubt, non-extension of the Term by the Company shall not constitute termination by the Company without Cause.

(viii)Non-Extension of Term by the Executive. The Executive may give notice of non-extension to the Company pursuant to Section 2(b).

Active 102093874.13.DOCX7

EXHIBIT 10.58

(ix)Resignation following a Change in Control. The Executive may resign from the Executive’s employment within sixty (60) days following a Change in Control.

(b)Notice of Termination. Any termination of the Executive’s employment by the Company or by the Executive under this Section 4 (other than a termination pursuant to Section 4(a)(i) above) shall be communicated by a written notice to the other party hereto: (i) indicating the specific termination provision in this Agreement relied upon, (ii) except with respect to a termination pursuant to Section 4(a) (iv), (vi), (vii), (viii), or (ix), setting forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated, and (iii) specifying a Date of Termination which, if submitted by the Executive (or, in the case of a termination described in Section 4(a)(ii), by the Company), shall be at least thirty (30) days following the date of such notice (a “Notice of Termination”); provided, however, that a Notice of Termination delivered by the Company pursuant to Section 4(a)(ii) shall not be required to specify a Date of Termination, in which case the Date of Termination shall be determined pursuant to Section 4(a)(ii); and provided, further, that in the event that the Executive delivers a Notice of Termination (other than a notice of non- extension under Section 4(a)(viii) above) to the Company, the Company may, in its sole discretion, accelerate the Date of Termination to any date that occurs following the date of Company’s receipt of such Notice of Termination (even if such date is prior to the date specified in such Notice of Termination). A Notice of Termination submitted by the Company may provide for a Date of Termination on the date the Executive receives the Notice of Termination, or any date thereafter elected by the Company in its sole discretion. The failure by the Company or the Executive to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause or Good Reason shall not waive any right of the Company or the Executive hereunder or preclude the Company or the Executive from asserting such fact or circumstance in enforcing the Company’s or the Executive’s rights hereunder.

(c)Post-Termination Assistance. Executive agrees to make reasonable efforts to assist the Company after the termination of Executive’s employment, including but not limited to, transitioning of Executive’s job duties as well as assisting with any legal proceeding, lawsuit, or claim involving matters occurring during Executive’s employment with the Company. The Company shall reimburse Executive for reasonable expenses incurred in connection with such cooperation.

(d)Deemed Resignations. Unless otherwise agreed to in writing by the Company and the Executive prior to the termination of the Executive’s employment, any termination of the Executive’s employment shall, without changing the basis for termination of employment or the impact of such termination on the Executive’s rights, if any, under this Agreement, constitute (i) an automatic resignation of the Executive from any position held as an officer of the Company and any of its Affiliates and (ii) an automatic resignation of the Executive from the Board (if applicable), from the board of directors or similar governing body of any Affiliate of the Company and from the board of directors or similar governing body of any corporation, limited liability entity or other entity in which the Company or any Affiliate holds an equity interest and with respect to which board or similar governing body the Executive serves as the Company’s or such Affiliate’s designee or other representative.

5.Company Obligations Upon Termination of Employment..

(a)In General. Upon a termination of the Executive’s employment for any reason, the Executive (or the Executive’s estate) shall be entitled to receive: (i) any portion of the Executive’s Annual Base Salary through the Date of Termination not theretofore paid, (ii) any expenses owed to the Executive under Section 3(f), (iii) any accrued but unused PTO pursuant to Section 3(e), and (iv) any amount arising from the Executive’s participation in, or benefits under,

Active 102093874.13.DOCX8

EXHIBIT 10.58

any employee benefit plans, programs or arrangements under Section 3(d), which amounts shall be payable in accordance with the terms and conditions of such employee benefit plans, programs or arrangements. Any Annual Bonus earned for any calendar year completed prior to the Date of Termination, but unpaid prior to such date, and any Prorated Termination Bonus owed pursuant to the last sentence of Section 3(b), shall be paid within sixty (60) days after the Date of Termination (but in any event on or prior to March 15 of the calendar year immediately following such completed calendar year with respect to which such Annual Bonus or Prorated Termination Bonus was earned). Except as otherwise set forth in Section 5(b) below, the payments and benefits described in this Section 5(a) shall be the only payments and benefits payable in the event of the Executive’s termination of employment for any reason.

(b)Severance Payment

(i)In addition to the payments and benefits described in Section 5(a) above, if the Executive’s employment shall be terminated by the Company without Cause pursuant to Section 4(a)(iv), by the Executive’s resignation for Good Reason pursuant to Section 4(a)(v), or due to non-extension of the Initial Term or any Extension Term by the Company pursuant to Section 4(a)(vii), the Company shall pay to Executive severance in the total gross amount equal to three (3) times the sum of (1) the Annual Base Salary for the year in which the Date of Termination occurs, and (2) the higher of the Target Annual Bonus or the Annual Bonus paid to the Executive in respect of the calendar year immediately preceding the year in which the Date of Termination occurs (the “Severance Payment”).

(ii)The Severance Payment shall be in lieu of notice or any other severance benefits to which the Executive might otherwise be entitled. Notwithstanding anything herein to the contrary, (A) no portion of the Severance Payment shall be paid unless, on or prior to the sixtieth (60th) day following the Date of Termination, the Executive timely executes a general waiver and release of claims agreement, in a form substantially similar to that attached to this Agreement as Exhibit B (the “Release”), which Release shall not have been revoked by the Executive prior to the expiration of the period (if any) during which any portion of such Release is revocable under applicable law, and (B) as of the first date on which the Executive violates any covenant contained in Section 7, any remaining unpaid portion of the Severance Payment shall thereupon be forfeited. Subject to the provisions of Section 9, the Severance Payment shall be paid in equal installments during the Severance Period, at the same time and in the same manner as the Annual Base Salary would have been paid had the Executive remained in active employment during the Severance Period, in accordance with the Company’s normal payroll practices in effect on the Date of Termination; provided that any installment that would otherwise have been paid prior to the first normal payroll payment date occurring on or after the sixtieth (60th) day following the Date of Termination (such payroll date, the “First Payment Date”) shall instead be paid on the First Payment Date. For purposes of Section 409A (including, without limitation, for purposes of Section 1.409A-2(b)(2)(iii) of the Department of Treasury Regulations), the Executive’s right to receive the Severance Payment in the form of installment payments (the “Installment Payments”) shall be treated as a right to receive a series of separate payments and, accordingly, each Installment Payment shall at all times be considered a separate and distinct payment.

(c)During the lesser of the period during which Executive or a qualifying beneficiary (as defined in Section 607 of ERISA) has in effect an election for post-termination continuation coverage for medical and dental benefits under applicable law, including Section 4980 of the Code (“COBRA”), or the period ending on the 18-month anniversary of the Date of Termination, Executive (or, if applicable, the qualifying beneficiary) shall be entitled to such coverage at an

Active 102093874.13.DOCX9

EXHIBIT 10.58

out-of-pocket premium cost that does not exceed the out-of-pocket premium cost applicable to similarly situated active employees (and their eligible dependents).

(d)The provisions of this Section 5 shall supersede in their entirety any severance payment provisions in any severance plan, policy, program or other arrangement maintained by the Company.

(e)Recharacterization of Termination. Notwithstanding any other provision of this Agreement, if, following the termination of employment and prior to a Change in Control, the Company discovers that grounds existed as of the Date of Termination for a termination for Cause, then such termination shall be deemed to be a termination for Cause and Executive shall only be entitled to the payments and benefits provided in Section 5(a). For the avoidance of doubt, this right to recharacterize a prior termination shall terminate effective as of a Change in Control. In the event Executive’s termination is reclassified as a termination for Cause pursuant to this Section 5(e), Executive’s termination shall be so treated and classified for all purposes under this Agreement and any other agreements between Executive and the Company, and Executive shall repay to the Company any monies or benefits received by Executive following termination to which Executive would not have been entitled upon being terminated for Cause.

6.Change in Control.

(a)Equity Awards. Notwithstanding anything to the contrary in this Agreement or any other agreement, including any LTIP and any award agreement thereunder, all equity awards granted under an LTIP to the Executive prior to the Effective Date and held by the Executive as of immediately prior to a Change in Control, to the extent unvested, shall become fully vested immediately prior to the Change in Control. For the avoidance of doubt the foregoing sentence shall not apply with respect to equity awards granted under an LTIP to the Executive after the Effective Date.

(b)Golden Parachute Excise Tax Protection. Notwithstanding any provision of this Agreement, if any portion of the payments or benefits provided to the Executive hereunder, or under any other agreement with the Executive or any plan, policy or arrangement of the Company or any of its Affiliates (in the aggregate, “Total Payments”), would constitute an “excess parachute payment” and would, but for this Section 6(b), result in the imposition on the Executive of an excise tax under Section 4999 of the Code (the “Excise Tax”), then the Total Payments to be made to the Executive shall either be (i) delivered in full, or (ii) reduced by such amount such that no portion of the Total Payments would be subject to the Excise Tax, whichever of the foregoing results in the receipt by the Executive of the greatest benefit on an after-tax basis (taking into account the applicable federal, state and local income taxes and the Excise Tax). The determination of whether a reduction in Total Payments is necessary and the amount of any such reduction shall be made by the Company in its reasonable discretion and in reliance on its tax advisors. If the Company so determines that a reduction in Total Payments is required, such reduction shall apply first pro rata to (A) cash payments subject to Section 409A of the Code as “deferred compensation” and (B) cash payments not subject to Section 409A of the Code (in each case with the cash payments otherwise scheduled to be paid latest in time reduced first), and then pro rata to (C) equity-based compensation subject to Section 409A of the Code as “deferred compensation” and (D) equity-based compensation not subject to Section 409A of the Code.

7.Restrictive Covenants.

(a)The Executive shall not, at any time during the Term or, in the event of a termination of Executive’s employment pursuant to Section 4(a)(iv), (v), or (vii), during the Restricted Period, directly or indirectly, (i) engage in the Restricted Business within the

Notwithstanding the foregoing, the Executive shall be permitted to acquire a passive stock or equity interest in such a business; provided that such stock or other equity interest is publicly traded and the amount acquired by Executive is not more than five percent (5%) of the outstanding interest in such business. Notwithstanding the foregoing, at any time during the Restricted Period, Executive may, at Executive’s option, serve on the Company a written notice waiving the right to any and all future installments of the Severance Payment pursuant to Section 5(b) (a “Severance Waiver Notice”), and upon delivery of the Severance Waiver Notice, Executive shall no longer be bound by the restrictions set forth in this Section 7(a) for the period on and after the date on which the Severance Waiver Notice is delivered to the Company; provided, however, that notwithstanding the delivery of a Severance Waiver Notice, Executive will continue to be bound by the remaining obligations set forth in this Agreement, including but not limited to those covenants of Executive set forth in Sections 7(b)-(g) hereof.

(b)The Executive shall not, at any time during the Term or during the Restricted Period, directly or indirectly, either for himself or on behalf of any other Person, (i) recruit or otherwise solicit or induce any employee of the Company to terminate his, her or its employment or arrangement with the Company, or otherwise change his, her or its relationship with the Company, (ii) hire, or cause to be hired, any person who was employed by the Company and served in a capacity of “vice president” (or any person serving in a capacity senior to vice president) at any time during the twelve (12)-month period immediately prior to the Date of Termination, or (iii) influence, induce, or encourage any customer, subscriber, or supplier of the Company to discontinue, reduce, or materially change its relationship or business with the Company.

The Executive’s obligation to maintain and not use, disseminate, disclose or publish, or use for the Executive’s benefit or the benefit of any Person, any Proprietary Information after the Date of Termination will continue so long as such Proprietary Information is not, or has not by legitimate means become, generally known and in the public domain (other than by means of the Executive’s direct or indirect disclosure of such Proprietary Information) and continues to be maintained as Proprietary Information by the Company. The parties hereby stipulate and agree that as between them, the Proprietary Information identified herein is important, material and affects the successful conduct of the businesses of the Company (and any successor or assignee of the Company).

(d)Upon termination of the Executive’s employment with the Company for any reason, the Executive will promptly deliver to the Company all correspondence, drawings, manuals, letters, notes, notebooks, reports, programs, plans, proposals, financial documents, or any other documents concerning the Company’s customers, business plans, marketing strategies, products or processes.

EXHIBIT 10.58

(e)The Executive may respond to a lawful and valid subpoena or other legal process but shall give the Company (if lawfully permitted to do so) the earliest possible notice thereof, and shall, as much in advance of the return date as possible, make available to the Company and its counsel the documents and other information sought, and shall assist such counsel in resisting or otherwise responding to such process. Upon notification from Executive of such subpoena or other legal process, the Company shall, at its reasonable expense, retain mutually acceptable legal counsel to represent Executive in connection with Executive’s response to any such subpoena or other legal process. The Executive may also disclose Proprietary Information if: (i) in the reasonable written opinion of counsel for the Executive furnished to the Company, such information is required to be disclosed for the Executive not to be in violation of any applicable law or regulation or (ii) the Executive is required to disclose such information in connection with the enforcement of any rights under this Agreement or any other agreements between the Executive and the Company.

(f)Executive shall refrain from publishing any oral or written statements about the Company or any of its Affiliates, or any of their respective officers, employees, shareholders, investors, directors, agents or representatives that are malicious, obscene, threatening, harassing, intimidating or discriminatory and which are designed to harm any of the foregoing, at any time; provided that the Executive may confer in confidence with the Executive’s legal representatives, make truthful statements to any government agency in sworn testimony, or make truthful statements as otherwise required by law. The Company agrees that, upon the termination of the Executive’s employment hereunder, it shall advise its directors and executive officers to refrain from publishing any oral or written statements about Executive that are malicious, obscene, threatening, harassing, intimidating or discriminatory and which are designed to harm Executive, at any time; provided that they may confer in confidence with the Company’s and their legal representatives and make truthful statements as required by law.

(g)Prior to accepting other employment or any other service relationship during the Restricted Period, the Executive shall provide a copy of this Section 7 to any recruiter who assists the Executive in obtaining other employment or any other service relationship and to any employer or Person with which the Executive discusses potential employment or any other service relationship.

(h)Executive agrees and hereby acknowledges that: (i) the provisions of this Section 7 do not impose a greater restraint than is necessary to protect the goodwill, trade secrets, or other business interests of the Company; (ii) such provisions contain reasonable limitations as to time, scope of activity, and geographical area to be restrained; (iii) the provisions of this Section 7 are necessary and essential to protect the Proprietary Information, trade secrets, and goodwill of the Company, as well as due to Executive’s position as an executive and/or management employee of the Company, and (iv) the consideration provided hereunder, including without limitation, the Proprietary Information provided to Executive, is sufficient to compensate Executive for the restrictions contained in this Section 7. In consideration of the foregoing and in light of Executive’s education, skills, and abilities, Executive agrees that Executive will not assert that, and it should not be considered that, any provisions of Section 7 otherwise are void, voidable, or unenforceable or should be voided or held unenforceable. In the event the terms of this Section 7 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

(i)As used in this Section 7, the term “Company” shall include the Company, its parent, Affiliates, related entities, and any of its direct or indirect subsidiaries.

EXHIBIT 10.58

8.Injunctive Relief. The Executive recognizes and acknowledges that a breach of the covenants contained in Section 7 will cause irreparable damage to the Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, the Executive agrees that in the event of a breach of any of the covenants contained in Section 7, in addition to any other remedy that may be available at law or in equity, the Company will be entitled to specific performance and injunctive relief.

9.Section 409A.

(a)General. The parties hereto acknowledge and agree that, to the extent applicable, this Agreement shall be interpreted in accordance with, and incorporate the terms and conditions required by, Section 409A. Notwithstanding any provision of this Agreement to the contrary, in the event that the Company determines that any amounts payable hereunder will be immediately taxable to the Executive under Section 409A, the Company reserves the right to (without any obligation to do so or to indemnify the Executive for failure to do so) (i) adopt such amendments to this Agreement or adopt such other policies and procedures (including amendments, policies and procedures with retroactive effect) that it determines to be necessary or appropriate to preserve the intended tax treatment of the benefits provided by this Agreement, to preserve the economic benefits of this Agreement and to avoid less favorable accounting or tax consequences for the Company and/or (ii) take such other actions it determines to be necessary or appropriate to exempt the amounts payable hereunder from Section 409A or to comply with the requirements of Section 409A and thereby avoid the application of penalty taxes thereunder.

EXHIBIT 10.58

without limitation, for purposes of Section 1.409A- 2(b)(2)(iii) of the Department of Treasury Regulations), each such payment that the Executive may be eligible to receive under this Agreement shall be treated as a separate and distinct payment; (v) to the extent that any reimbursements or corresponding in-kind benefits provided to the Executive under this Agreement are deemed to constitute “deferred compensation” under Section 409A, such reimbursements or benefits shall be provided reasonably promptly, but in no event later than December 31 of the year following the year in which the expense was incurred, and in any event in accordance with Section 1.409A-3(i)(1)(iv) of the Department of Treasury Regulations; and (vi) the amount of any such payments or expense reimbursements in one calendar year shall not affect the expenses or in-kind benefits eligible for payment or reimbursement in any other calendar year, other than an arrangement providing for the reimbursement of medical expenses referred to in Section 105(b) of the Code, and the Executive’s right to such payments or reimbursement of any such expenses shall not be subject to liquidation or exchange for any other benefit.

14.Entire Agreement. This Agreement (together with any other agreements and instruments contemplated hereby or referred to herein) is intended by the parties hereto to be the final expression of their agreement with respect to the employment of the Executive by the Company and may not be contradicted by evidence of any prior or contemporaneous agreement (including, without limitation, any term sheet or offer letter). The parties hereto further intend that this Agreement shall constitute the complete and exclusive statement of its terms and that no extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of this Agreement.

15.Amendments; Waivers.

By an instrument in writing similarly executed and approved by the Board, the Executive or a duly authorized officer of the Company may waive compliance by the other party or parties hereto with any provision of this Agreement that such other party was or is obligated to comply with or perform; provided, however, that such waiver shall not operate as a waiver of, or estoppel with respect to, any other or subsequent failure to comply or perform.

Due to the interstate nature of the Company’s operations, the parties agree that the Federal Arbitration Act shall apply to this Agreement. Arbitration may be compelled, and judgment may be entered on the arbitration award in any court having jurisdiction; provided, however, that the Company shall be entitled to seek a restraining order or injunction in any court of competent jurisdiction to prevent any continuation of any violation of the provisions of Section 7, and the Executive hereby consents that such restraining order or injunction may be granted without requiring the Company to post a bond (or, if required by applicable law, a bond of $500).

Failure of the Company to demand strict compliance with any of the terms, covenants or conditions hereof will not be deemed a waiver of the term, covenant or condition, nor will any waiver or relinquishment by the Company of any right or power under this Agreement at any one time or more times be deemed a waiver or relinquishment of the right or power at any other time or times.

22.Withholding. The Company shall be entitled to withhold from any amounts payable under this Agreement, any federal, state, local or foreign withholding or other taxes or charges which the Company is required to withhold.

Executive is, and will continue to be, in full compliance with any nondisclosure, non-disparagement, non-competition, and non-solicitation obligations owed to the Company Parties under any agreement or applicable law. Executive further represents and warrants that Executive has returned all information and property as required by Section 7(d) of the Employment Agreement.

4.Reporting to Government Agencies. Nothing in this Release Agreement or in any other agreement referenced in this Release Agreement shall prevent Executive from filing a charge or complaint or making a disclosure or report of possible unlawful activity, including a challenge to the validity of this Release Agreement, with any governmental agency, including but not limited to the Equal Employment Opportunity Commission (“EEOC”), the National Labor Relations Board (“NLRB”), or the SEC, or from participating in any investigation or proceeding conducted by the EEOC, NLRB, SEC, or any federal, state or local agency. This Release Agreement does not impose any condition precedent (such as prior disclosure to any Released Party), any penalty, or any other restriction or limitation adversely affecting Executive’s rights regarding any governmental agency disclosure, report, claim or investigation. Executive understands and recognizes, however, that even if a report or disclosure is made or a charge is filed by Executive or on Executive’s behalf with a governmental agency other than the SEC, Executive will not be entitled to any damages or payment of any money or other relief personal to Executive relating to any event which occurred prior to Executive’s execution of this Release Agreement.

5.Entire Agreement. Executive has carefully read and fully understands all of the terms of this Release Agreement. Executive agrees that this Release Agreement, together with the Employment Agreement, constitutes the complete agreement of the Parties in respect of the subject matter hereof and shall supersede all prior agreements between the Parties in respect of the subject matter hereof except to the extent set forth herein. For the avoidance of doubt, however, nothing in this Release Agreement shall constitute a waiver of any of the Company Parties’ rights to enforce any obligations of the Executive under the Employment Agreement that survive the Employment Agreement’s termination, including without limitation, any obligations concerning arbitration, confidentiality, non-competition, non-solicitation, and post-employment cooperation.

6.No Admission. Executive understands this Release Agreement is not and shall not be deemed or construed to be an admission by any of the Released Parties of any wrongdoing of any kind or of any breach of any contract, law, obligation, policy, or procedure of any kind or nature.

7.Injunctive Relief. Executive acknowledges that damages may be difficult to calculate and/or wholly inadequate for certain breaches of this Release Agreement. The Released Parties may seek immediate injunctive or other equitable relief to enforce the terms of this Release Agreement, in addition to any legal or other relief to which the Released Parties may be entitled, including damages and attorneys’ fees.

8.Representations; Modifications; Severability. Executive acknowledges that Executive has not relied upon any representations or statements, written or oral, not set forth in this Release Agreement. This Release Agreement cannot be modified except in writing and signed by all Parties. The foregoing notwithstanding, if any part of this Release Agreement is found to be unenforceable by a court of competent jurisdiction, then such unenforceable portion will be modified to be enforceable, or severed from this Release Agreement if it cannot be

modified, and such modification or severance shall have no effect upon the remaining portions of the Release Agreement which shall remain in full force and effect.

9.Assignment and Successors. The Company may, without Executive’s consent, assign its rights and obligations under this Agreement to any entity, including any successor to all or substantially all the assets of the Company, by merger or otherwise. The Executive may not assign the Executive’s rights or obligations under this Agreement to any individual or entity. This Agreement shall be binding upon and inure to the benefit of the Company, the Executive and their respective successors, assigns, personnel and legal representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable.

10.Governing Law. This Agreement shall be governed, construed, interpreted and enforced in accordance with the substantive laws of the State of Delaware, without reference to the principles of conflicts of law of Delaware or any other jurisdiction, and where applicable, the laws of the United States

11.Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original, but all of which together will constitute one and the same Agreement.
