EMPLOYMENT AGREEMENT

EXHIBIT 10.26

THIS EMPLOYMENT AGREEMENT (this “Agreement”) by and between GEMPHIRE THERAPEUTICS INC., a Delaware corporation (the “Company”) and XXXX X. XXXX (the “Executive”) is signed by the Company and the Executive on August 15, 2016 (the “Effective Date”).

BACKGROUND

The board of directors of the Company (the “Board”) has determined that it is in the best interests of the Company and its stockholders to employ the Executive. The Executive is currently employed as its Chief Commercial Officer subject to an offer letter dated August 6, 2015 and effective August 10, 2015, (the “Prior Agreement”). The Company and the Executive desire to enter into this Agreement to embody the terms of those continued relationships and to amend, restate and supersede the terms and conditions of the Prior Agreement in their entirety. This Agreement shall represent the entire understanding and agreement between the parties with respect to the Executive’s employment with the Company.

NOW, THEREFORE, in consideration of the foregoing and the terms and conditions set forth herein, the parties agree as follows:

TERMS AND CONDITIONS

1. EMPLOYMENT PERIOD. The Company hereby agrees to continue the Executive in its employ, and the Executive hereby agrees to remain in the employ of the Company, subject to the terms and conditions of this Agreement, for the period commencing on the Effective Date and ending on the first anniversary of the Effective Date (the “Initial Term”). The term of this Agreement will automatically be renewed for a term of one (1) year (each, a “Renewal Term”) at the end of the Initial Term and at the end of each Renewal Term thereafter, provided that the Board does not provide written notice to the Executive of its intention not to renew this Agreement ninety (90) days prior to the expiration of the Initial Term or any Renewal Term. For purposes of this Agreement, “Employment Period” includes the Initial Term and any Renewal Term(s) thereafter. Notwithstanding the foregoing, in the event of a Change in Control, the date the Change in Control occurs shall become the Effective Date for all purposes thereafter, and each Change in Control thereafter shall result in a new Effective Date on the date of the latest Change in Control. This Agreement, on the Effective Date, amends, restates and supersedes the Prior Agreement.

2. TERMS OF EMPLOYMENT.

(a) Position and Duties.

(i) During the Employment Period, the Executive shall serve as the Chief Commercial Officer of the Company, and in such other position or positions with the

Company and its subsidiaries as are consistent with the Executive’s position as Chief Commercial Officer of the Company, and shall have such duties and responsibilities as are assigned to the Executive by the Board consistent with the Executive’s position as Chief Commercial Officer of the Company.

(ii) During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive agrees to devote reasonable attention and time during normal business hours and on a full time basis to the business and affairs of the Company, to discharge the responsibilities assigned to the Executive hereunder, and to use the Executive’s reasonable best efforts to perform faithfully and efficiently such responsibilities. During the Employment Period it shall not be a violation of this Agreement for the Executive to (A) be employed by the Company or any of its subsidiaries or Affiliates, (B) serve on corporate, civic or charitable boards, committees, or advisory boards, (C) deliver lectures, fulfill speaking engagements or teach at educational institutions, and (D) manage personal investments, so long as such activities do not significantly interfere with the performance of the Executive’s responsibilities as an employee of the Company in accordance with this Agreement.

During the Employment Period, the Annual Base Salary shall be reviewed at least annually by the Board or the Compensation Committee of the Board (the “Compensation Committee”). Any increase in the Annual Base Salary shall not serve to limit or reduce any other obligation to the Executive under this Agreement. The Annual Base Salary shall not be reduced after any such increase (unless otherwise agreed to by the Executive) and the term “Annual Base Salary” as utilized in this Agreement shall refer to the Annual Base Salary as so increased or adjusted.

(ii) Annual Bonus. In addition to the Annual Base Salary, for each fiscal year ending during the Employment Period, the Executive shall be eligible for an annual cash bonus (the “Annual Bonus”), as determined by the Compensation Committee, which value shall be up to forty (40) percent of the Annual Base Salary and as determined in accordance with the policies and practices generally applicable to other senior executive officers of the Company. Each such Annual Bonus awarded to the Executive shall be paid sometime during the first seventy-five (75) days of the fiscal year next following the fiscal year for which the Annual Bonus is awarded, unless the Executive shall elect, in compliance with Treasury Regulation 1.409A-2(a), to defer the receipt of such Annual Bonus.

(iv) Welfare Benefit Plans. During the Employment Period, the Executive and/or the Executive’s family, as the case may be, shall be eligible for participation in and shall receive all benefits under welfare benefit plans, practices, policies and programs provided by the Company and its Affiliated companies (including, without limitation, medical, prescription, dental, disability, employee life, group life, accidental death and travel accident insurance plans and programs) made available to other senior executive officers of the Company.

As of the Effective Date, the Executive shall be entitled to retain all shares of the Company’s common stock (the “Common Stock”) and stock options held by the Executive as of the Effective Date (the “Executive’s Current Equity”); provided, however, to the extent that the Executive remains employed by the Company as of the closing date of a Change in Control, the Executive’s Current Equity shall fully vest effective as of the closing date of a Change in Control.

(vi) Expenses. During the Employment Period, the Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by the Executive in accordance with the plans, practices, policies and programs of the Company.

contingency, shall be paid or provided in accordance with and subject to the terms and provisions of such plans, it being understood that all such benefits shall be determined on the basis of the actual date of termination of the Executive’s employment with the Company.

(e) Conditional Benefits. For purposes of this Agreement, the “Conditional Benefits” to which the Executive may become entitled are as follows:

(i) Severance Amount. The Company shall pay the Executive a lump sum amount equal to the Severance Amount. Subject to Section 3(c)(iii) above, the Severance Amount shall be paid on the date that is sixty (60) days after the Termination Date (or upon the Executive’s death, if earlier).

(ii) COBRA. Provided that the Executive timely elects continued health insurance coverage under the federal COBRA law, the Company will pay one-hundred percent of the cost of premiums for such health insurance continuation coverage during the twelve (12) months following the Termination Date.

(v) Additional Distribution Rules. Notwithstanding any other payment date or schedule provided in this Agreement to the contrary, if the Executive is deemed on the Termination Date of the Executive’s employment to be a “specified employee” within the meaning of that term under Section 409A of the Code and the regulations thereunder (“Section 409A”), then each of the following shall apply:

(A) With regard to any payment that is considered “nonqualified deferred compensation” under Section 409A and payable on account of a “separation from service” (within the meaning of Section 409A and as provided in Section 3(g) of this Agreement), such payment shall not be made prior to the date which is the earlier of (1) the expiration of the six (6)-month period measured from the date of the Executive’s “separation from service,” and (2) the date of the Executive’s death (the “Delay Period”) to the extent required under Section 409A. Upon the expiration of the Delay Period, all payments delayed pursuant to this Section 3(e)(v)(A) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid to the Executive in a lump sum, and all remaining payments due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein; and

(B) To the extent that benefits to be provided during the Delay Period are considered “nonqualified deferred compensation” under Section 409A provided on account of a “separation from service,” the Executive shall pay the cost of such benefits during the Delay Period, and the Company shall reimburse the Executive, to the extent that such costs would otherwise have been paid or reimbursed by the Company or to the extent that such benefits would otherwise have been provided by the Company at no cost to the Executive, for the Company’s share of the cost of such benefits upon expiration of the Delay Period, and any remaining benefits shall be paid, reimbursed or provided by the Company in accordance with the procedures specified herein.

The foregoing provisions of this Section 3(e)(v)(A) shall not apply to any payments or benefits that are excluded from the definition of “nonqualified deferred compensation” under Section 409A, including, without limitation, payments excluded from the definition of “nonqualified deferred compensation” on account of being separation pay due to an involuntary separation from service under Treasury Regulation 1.409A-1(b)(9)(iii) or on account of being a “short-term deferral” under Treasury Regulation 1.409A-1(b)(4).

(f) Definitions. For purposes of this Agreement, the following terms shall have the meanings ascribed to them below:

(i) “Affiliate” means any corporation, partnership, limited liability company, trust or other entity which directly, or indirectly through one or more intermediaries, controls, is under common control with, or is controlled by, the Company.

Notwithstanding the foregoing, a Change in Control will not be deemed to occur (1) in connection with the issuance of securities of the Company as part of a joint venture or strategic partnership to which the Company is party, (2) on account of the acquisition of securities of the Company directly from the Company, (3) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities, (4) on account of the acquisition of securities of the Company by any individual who is, on the IPO Date, either an executive officer or a member of the Board (either, an “IPO Investor”) and/or any entity in which an IPO Investor has a direct or indirect interest (whether in the form of voting rights or participation in profits or capital contributions) of more than 50% (collectively, the “IPO Entities”), (5) on account of the IPO Entities continuing to hold shares that come to represent more than 50% of the combined Voting Power of the Company’s then outstanding securities as a result of the conversion of any class of the Company’s securities into another class of the Company’s securities having a different number of votes per share pursuant to the conversion provisions set forth in the Company’s Amended and Restated Certificate of Incorporation, or (6) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding Voting Securities as a result of a repurchase or other acquisition of Voting Securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of Voting Securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional Voting Securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding Voting Securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control will be deemed to have occurred;

(B) a merger, consolidation or similar transaction involving (directly or indirectly) the Company is consummated and, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (1) outstanding voting securities representing more than 50% of the combined outstanding voting power of the surviving entity in such merger, consolidation or similar transaction or (2) more than 50% of the combined outstanding voting power of the parent of the surviving entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction; provided, however, that a merger, consolidation or similar transaction will not constitute a Change in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting power of the surviving entity or its parent are owned by the IPO Entities;

(C) a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company and its subsidiaries is consummated, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its subsidiaries to an entity, more than 50% of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease, license or other disposition; provided, however, that a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company and its subsidiaries will not constitute a Change in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting power of the acquiring entity or its parent are owned by the IPO Entities; or

(D) individuals who, on the Effective Date, are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member will, for purposes of this Agreement, be considered as a member of the Incumbent Board.

Notwithstanding the foregoing definition, in the case of any payment or benefit that constitutes nonqualified deferred compensation under Section 409A of the Code, if necessary in order to ensure that the Executive does not incur liability for additional tax under Section 409A of the Code, a transaction (or series of related transactions) shall constitute a Change in Control only if, in addition to satisfying the foregoing definition, such transaction (or series of related transactions) also satisfies the definition of a “change in control event” under Treas. Reg. Section 1.409A-3(i)(5).

(iii) “Code” means the Internal Revenue Code of 1986, as amended and the rules and regulations promulgated thereunder.

(iv) “Earned Compensation” means any Annual Base Salary earned, but unpaid, for services rendered to the Company on or prior to the date on which the Employment Period ends pursuant to Section 3(a) (but excluding any salary and interest accrued thereon payment of which has been deferred).

Any question as to the existence, extent or potentiality of the Executive’s disability shall be determined by a qualified physician selected by the Company with the consent of the Executive, which consent shall not be unreasonably withheld. The Executive or the Executive’s legal representatives or any adult member of the Executive’s immediate family shall have the right to present to such physician such information and arguments as to the Executive’s disability as he, she or they deem appropriate, including the opinion of the Executive’s personal physician.

Notwithstanding the foregoing, a termination shall not be treated as a Termination for Good Reason if the Executive shall have consented in writing to the occurrence of the event giving rise to the claim of Termination for Good Reason.

(xviii) “Termination Right” means the right of the Company, in its sole, absolute and unfettered discretion, to terminate the Executive’s employment under this Agreement for any reason or no reason whatsoever. For the avoidance of doubt, any Termination for Cause effected by the Company shall not constitute the exercise of its Termination Right.

(xix) “Voting Power” means such number of Voting Securities as shall enable the holders thereof to cast all the votes which could be cast in an annual election of directors of a company.

(xx) “Voting Securities” means all securities entitling the holders thereof to vote in an annual election of directors of a company.

(g) Conflict with Plans. As permitted under the terms of the applicable Plans, the Company and the Executive agree that the definitions of Termination for Cause or Termination for Good Reason set forth in this Section 3 shall apply in place of any similar definition or comparable concept applicable under either of the Plans (or any similar definition in any successor plan).

(h) Section 409A. It is intended that payments and benefits under this Agreement either be excluded from or comply with the requirements of Section 409A and the guidance issued thereunder and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted consistent with such intent. In the event that any provision of this Agreement is subject to but fails to comply with Section 409A, the Company may revise the terms of the provision to correct such noncompliance to the extent permitted under any guidance, procedure or other method promulgated by the Internal Revenue Service now or in the future or otherwise available that provides for such correction as a means to avoid or mitigate any taxes, interest or penalties that would otherwise be incurred by the Executive on account of such noncompliance. Provided, however, that in no event whatsoever shall the Company be liable for any additional tax, interest or penalty imposed upon or other detriment suffered by the Executive under Section 409A or damages for failing to comply with Section 409A. Solely for purposes of determining the time and form of payments due the Executive under this Agreement (including any payments due under Sections 3(c) or 5) or otherwise in connection with the Executive’s termination of employment with the Company, the Executive shall not be deemed to have incurred a termination of employment unless and until the Executive shall incur a “separation from service” within the meaning of Section 409A. The parties agree, as permitted in accordance with the final regulations thereunder, a “separation from service” shall occur when the Executive and the Company reasonably anticipate that the Executive’s level of bona fide services for the Company (whether as an employee or an independent contractor) will permanently decrease to no more than forty (40) percent of the average level of bona fide services performed by the Executive for the Company over the immediately preceding thirty-six (36) months. The determination of whether and when a separation from service has occurred shall be made in accordance with this subparagraph and in a manner consistent with Treasury Regulation Section 1.409A-1(h). All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A, including, where applicable, the requirements that (i) any reimbursement is for expenses incurred during the Executive’s lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount of expenses eligible for reimbursement (and the in-kind benefits to be provided) during a calendar year may not affect the expenses eligible for reimbursement (and the in-kind benefits to be provided) in any other calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the expense is incurred, and (iv) the right to reimbursement (or in-kind benefits) is not subject to set off or liquidation or exchange for any other benefit. For purposes of Section 409A, the Executive’s right to any installment payments under this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within ninety (90) days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company.

4. EXECUTIVE REMEDY. The Executive shall be under no obligation to seek other employment or other engagement of the Executive’s services. The Executive acknowledges and agrees that the payment and rights provided under Section 3 are fair and reasonable, and are the Executive’s sole and exclusive remedy, in lieu of all other remedies at law or in equity, for termination of the Executive’s employment by the Company upon exercise of its Termination Right pursuant to this Agreement or upon a Termination for Good Reason.

5. ADDITIONAL PAYMENTS FOLLOWING A CHANGE IN CONTROL.

(a) If, during the Employment Period and within two (2) years after a Change in Control, the Company shall terminate the Executive’s employment other than due to the Executive’s death, a Termination for Cause, a Termination due to Disability or if the Executive shall effect a Termination for Good Reason:

(i) the Company shall pay to the Executive, in a lump sum in cash within thirty (30) days after the Termination Date, the aggregate of the following amounts:

(A) the Unconditional Entitlements;

(B) the amount equal to the product of 1 times the sum of (y) the Annual Base Salary, and (z) the greater of the target bonus for the then current fiscal year under the Plans or any successor annual bonus plan and the average Annual Bonus paid to or for the benefit of the Executive for the prior three (3) full years (or any shorter period during which the Executive has been employed by the Company), and

(ii) the Company shall provide the Executive the Conditional Benefits minus the Severance Amount.

(b) If any payment or benefit (including payments and benefits pursuant to this Agreement) the Executive would receive in connection with a Change in Control from the Company or otherwise (the “Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this paragraph, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Company shall cause to be determined, before any amounts of the Payment are paid to the Executive, which of the following two alternative forms of payment shall be paid to the Executive: (A) payment in full of the entire amount of the Payment (a “Full Payment”), or (B) payment of only a part of the Payment so that the Executive receives the largest payment possible without the imposition of the Excise Tax (a “Reduced Payment”). A Full Payment shall be made in the event that the amount received by the Executive on a net after-tax basis is greater than what would be received by the Executive on a net after-tax basis if the Reduced Payment were made, otherwise a Reduced Payment shall be made. If a Reduced Payment is made, (i) the Payment shall be paid only to the extent permitted under the Reduced Payment alternative, and the Executive shall have no rights to any additional payments and/or benefits constituting the Payment, and (ii) reduction in payments and/or benefits shall occur in the following order: (A) reduction of cash payments; (B) cancellation of accelerated vesting of equity awards other than stock options; (C) cancellation of accelerated vesting of stock options; and (D) reduction of other benefits paid to Executive. In the event that acceleration of compensation from the Executive’s equity awards is to be reduced, such acceleration of vesting shall be canceled in the reverse order of the date of grant.

(c) The independent registered public accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change in Control, or a nationally recognized law firm, shall make all determinations required to be made under this Section 5. If the independent registered public accounting firm or nationally

recognized law firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint a nationally recognized law firm or independent registered public accounting firm or law firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such independent registered public accounting firm required to be made hereunder.

(d) The independent registered public accounting firm or law firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the Company and the Executive within fifteen (15) calendar days after the date on which Executive’s right to a Payment is triggered (if requested at that time by the Company or Executive) or such other time as requested by the Company or Executive. Any good faith determinations of the accounting firm or law firm made hereunder shall be final, binding and conclusive upon the Company and Executive.

(e) The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement and such amounts shall not be reduced whether or not the Executive obtains other employment. The Company agrees to pay as incurred, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest (regardless of the outcome thereof) by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof (including as a result of any contest by the Executive about the amount of any payment pursuant to this Agreement), plus, in each case, interest on any delayed payment at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the Code.

6. CONFIDENTIALITY.

(a) Confidentiality. Without the prior written consent of the Company, except (y) as reasonably necessary in the course of carrying out the Executive’s duties hereunder or (z) to the extent required by an order of a court having competent jurisdiction or under subpoena from an appropriate government agency, the Executive shall not disclose any Confidential Information unless such Confidential Information has been previously disclosed to the public by the Company or has otherwise become available to the public (other than by reason of the Executive’s breach of this Section 6(a)). The term “Confidential Information” shall include, but shall not be limited to: (i) the identities of the existing and prospective customers or clients of the Company and its Affiliates, including names, addresses, credit status, and pricing levels; (ii) the buying and selling habits and customs of existing and prospective customers or clients of the Company and its Affiliates; (iii) financial information about the Company and its Affiliates; (iv) product and systems specifications, concepts for new or improved products and other product or systems data; (v) the identities of, and special skills possessed by, employees of the Company and its Affiliates; (vi) the identities of and pricing information about the suppliers and vendors of the Company and its Affiliates; (vii) training programs developed by the

Company or its Affiliates; (viii) pricing studies, information and analyses; (ix) current and prospective products and inventories; (x) financial models, business projections and market studies; (xi) the financial results and business conditions of the Company and its Affiliates; (xii) business plans and strategies of the Company and its Affiliates; (xiii) special processes, procedures, and services of suppliers and vendors of the Company and its Affiliates; and (xiv) computer programs and software developed by the Company or its Affiliates.

(b) Company Property. Promptly following the Executive’s termination of employment, the Executive shall return to the Company all property of the Company, and all copies thereof in the Executive’s possession or under the Executive’s control, except that the Executive may retain the Executive’s personal notes, diaries, rolodexes, mobile devices, calendars and electronic calendars, and correspondence of a personal nature.

(c) Nonsolicitation. The Executive agrees that, while the Executive is employed by the Company and during the one-year period following the Executive’s termination of employment with the Company (the “Restricted Period”), the Executive shall not directly or indirectly, (i) solicit any individual who is, on the Termination Date (or was, during the six-month period prior to the Termination Date), employed by the Company or its Affiliates to terminate or refrain from renewing or extending such employment or to become employed by or become a consultant to any other individual or entity other than the Company or its Affiliates or (ii) induce or attempt to induce any customer or investor (in each case, whether former, current or prospective), supplier, licensee or other business relation of the Company or any of its Affiliates to cease doing business with the Company or such Affiliate, or in any way interfere with the relationship between any such customer, investor, supplier, licensee or business relation, on the one hand, and the Company or any of its Affiliates, on the other hand. Any payments owed to Executive at time of separation as described herein shall be contingent upon Executive’s compliance with the post-employment nonsolicitation provisions.

(d) Noncompetition. The Executive agrees that, during the Restricted Period, the Executive shall not be employed by, serve as a consultant to, or otherwise assist or directly or indirectly provide services to a Competitor (as defined below) if (i) the services that the Executive is to provide to the Competitor are the same as, or substantially similar to, any of the services that the Executive provided to the Company or the Affiliates, and such services are to be provided with respect to any location in which the Company or an Affiliate had material operations during the twelve (12) month period prior to the Termination Date, or with respect to any location in which the Company or an Affiliate had devoted material resources to establishing operations during the twelve (12) month period prior to the Termination Date; or (ii) the trade secrets, Confidential Information, or proprietary information (including, without limitation, confidential or proprietary methods) of the Company and the Affiliates to which the Executive had access could reasonably be expected to benefit the Competitor if the Competitor were to obtain access to such secrets or information. For purposes of this paragraph, services provided by others shall be deemed to have been provided by the Executive to Competitor if the Executive had material supervisory responsibilities with respect to the provision of such services. The term “Competitor” means any enterprise (including a person, firm, business, division, or other unit, whether or not incorporated) during any period in which a material portion of its business is (and during any period in which it intends to enter into business activities that would be) materially competitive in any way with any business in which the Company or any of the Affiliates were

engaged during the twelve (12) month period prior to the Executive’s Termination Date (including, without limitation, any business if the Company devoted material resources to entering in such business during such twelve (12) month period), but for purposes of clause (c) above, the term “Competitor “ shall be limited to those businesses to which the Executive devoted more than an insignificant amount of time while employed by the Company. Notwithstanding the foregoing, the term “Competitor” shall not include a business of a Competitor if such business would not, as a stand-alone enterprise, constitute a “Competitor” under the foregoing definition, provided that Executive does not render any services to, or otherwise assist the portion of the business that competes with the Company and its Affiliates. For the avoidance of doubt, the Company’s and Affiliates’ businesses shall include, without limitation, the lines of business set forth in the Company’s annual report on Form 10-K, provided that nothing in this sentence shall be construed to limit the type of business of the Company and the Affiliates or the restrictions with respect to such businesses in the future. Any payments owed to Executive at time of separation as described herein shall be contingent upon Executive’s compliance with the post-employment noncompetition provisions.

(e) Equitable Remedies. The Executive acknowledges that the Company would be irreparably injured by a violation of Section 6 and the Executive agrees that the Company, in addition to any other remedies available to it for such breach or threatened breach, on meeting the standards required by law, shall be entitled to a preliminary injunction, temporary restraining order, or other equivalent relief, restraining the Executive from any actual or threatened breach of Section 6. If a bond is required to be posted in order for the Company to secure an injunction or other equitable remedy, the parties agree that said bond need not be more than a nominal sum.

(f) Employee Proprietary Information and Inventions Assignment. The terms of that certain Employee Proprietary Information, Inventions Assignment and Non-Competition Agreement between the Executive and the Company dated August 6, 2015 are hereby incorporated by reference (the “Invention Assignment Agreement”). To the extent that there are any conflicts between the terms and conditions of the Invention Assignment Agreement and this Agreement, the terms and conditions of this Agreement shall control. All non-conflicting terms of the Invention Assignment Agreement are hereby expressly preserved.

(g) Severability; Blue Pencil. The Executive acknowledges and agrees that the Executive has had the opportunity to seek advice of counsel in connection with this Agreement and the restrictive covenants contained herein are reasonable in geographical scope temporal duration and in all other respects. If it is determined that any provision of this Section 6 is invalid or unenforceable, the remainder of the provisions of this Section 6 shall not thereby be affected and shall be given full effect, without regard to the invalid portions. If any court or other decision-maker of competent jurisdiction determines that any of the covenants in this Section 6 is unenforceable because of the duration or geographic scope, of such provision, then after such determination becomes final and unappealable, the duration or scope of such provision, as the case may be, shall be reduced so that such provision becomes enforceable, and in its reduced form, such provision shall be enforced.

7. SUCCESSORS.

(a) This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives.

(b) This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns and any party acting in the form of a receiver or trustee capacity.

(c) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise.

8. MISCELLANEOUS.

(a) This Agreement shall be construed, and the rights and obligations of the parties hereunder determined, in accordance with the substantive laws of the State of Michigan, without regard to its conflict-of-laws principles. For the purposes of any suit, action or proceeding based upon, arising out of or relating to this Agreement or the negotiation, execution or performance hereof, the parties hereby expressly submit to the jurisdiction of all federal and state courts sitting within the confines of the Federal Eastern District of Michigan (the “Venue Area”) and consent that any order, process, notice of motion or other application to or by any such court or a judge thereof may be served within or without such court’s jurisdiction by registered mail or by personal service in accordance with Section 8(b). The parties agree that such courts shall have the exclusive jurisdiction over any such suit, action or proceeding commenced by either or both of said parties. Each party hereby irrevocably waives any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding based upon, arising out of or relating to this Agreement or the negotiation, execution or performance hereof, brought in any federal or state court sitting within the confines of the Venue Area and hereby further irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. The captions of this Agreement are not part of the provisions hereof and shall have no force or effect. This Agreement may not be amended or modified otherwise than by a written agreement executed by the parties hereto or their respective successors and legal representatives.
