The Company may terminate Executive’s employment immediately upon the occurrence of a Disability, with such termination to be effective upon Executive’s receipt of written notice of such termination. Upon Executive’s death or in the event that Executive’s employment is terminated due to his Disability, Executive or his estate or his beneficiaries, as the case may be, shall be entitled to:

(i) The Accrued Obligations; and

(ii) Any unpaid Bonus in respect of any completed fiscal year or quarter, as applicable, that has ended prior to the date of such termination, which amount shall be paid at such time bonuses are paid to other senior executives of the Company, but in no event later than the date that is 75 days following the last day of the fiscal year in which such termination occurred; and

(iii) Subject to satisfaction of the applicable performance objectives applicable for the fiscal year and/or quarter, as applicable, in which such termination occurs, an amount equal to (A) the Annual Bonus and/or Quarterly Bonus otherwise payable to Executive for the fiscal year or quarter, as applicable, in which such termination occurred, assuming Executive had remained employed through the applicable payment date, multiplied by (B) a fraction, the numerator of which is the number of days elapsed from the commencement of such fiscal year or quarter, as applicable, through the date of such termination and the denominator of which is 365 (or 366, as applicable) or 91 (or 92, as applicable) (the “Pro Rata Bonus Amount”), which amount shall be paid at such time bonuses are paid to other senior executives of the Company, but in no event later than the date that is 75 days following the last day of the fiscal year in which such termination occurred.

Following Executive’s death or a termination of Executive’s employment by reason of a Disability, except as set forth in this Section 7(c), Executive shall have no further rights to any compensation or any other benefits under this Agreement.

(d) Termination by the Company for Cause.

(i) The Company may terminate Executive’s employment at any time for Cause, effective upon delivery to Executive of written notice of such termination; provided, however, that with respect to any Cause termination relying on (i), (ii) or (iv) of the definition of Cause, to the extent that such act or acts or failure or failures to act are curable, Executive shall be given not less than thirty (30) days’ written notice by the Board of the Company’s intention to terminate him for Cause, such notice to state in detail the particular act or acts or failure or failures to act that constitute the grounds on which the proposed termination for Cause is based, and such termination shall be effective at the expiration of such thirty (30) day notice period unless Executive has fully cured such act or acts or failure or failures to act that give rise to Cause during such period.

(ii) In the event that the Company terminates Executive’s employment for Cause, he shall be entitled only to the Accrued Obligations. Following such termination of Executive’s employment for Cause, except as set forth in this Section 7(d)(ii), Executive shall have no further rights to any compensation or any other benefits under this Agreement.

(e) Termination by the Company without Cause. The Company may terminate Executive’s employment at any time without Cause, effective upon delivery to Executive of written notice of such termination. In the event that Executive’s employment is terminated by the Company without Cause (other than due to death or Disability), Executive shall be entitled to:

(i) The Accrued Obligations;

(iii) The Pro Rata Bonus Amount, which amount shall be paid at such time bonuses are paid to other senior executives of the Company, but in no event later than the date that is 75 days following the last day of the fiscal year in which such termination occurred;

(iv) An amount equal to the Base Salary, such amount to be paid in substantially equal payments during the Severance Term, and payable in accordance with the Company’s regular payroll practices; and

(v) Subject to Executive’s election of COBRA continuation coverage under the Company’s group health plan, payment, on the first regularly scheduled payroll date of each month during the Severance Term, of an amount equal to the difference between the monthly COBRA premium cost to continue coverage for Executive and his then covered dependents and the monthly contribution paid by active employees for the same coverage; provided, that the payments described in this clause (v) shall cease earlier than the expiration of the Severance Term in the event that Executive becomes eligible to receive any health benefits as a result of subsequent employment or service during the Severance Term.

Notwithstanding the foregoing, the payments and benefits described in clauses (ii), (iii), (iv) and (v) above shall immediately terminate, and the Company shall have no further obligations to Executive with respect thereto, in the event that Executive breaches any provision set forth in Section 9 hereof. Following such termination of Executive’s employment by the Company without Cause, except as set forth in this Section 7(e), Executive shall have no further rights to any compensation or any other benefits under this Agreement. For the avoidance of doubt, Executive’s sole and exclusive remedy upon a termination of employment by the Company without Cause shall be receipt of the Severance Benefits; provided, that the Company shall reimburse Executive for reasonable, documented attorneys’ fees actually incurred in connection with the enforcement of this Agreement to the extent Executive is successful in such enforcement action, not to exceed $50,000.

(f) Termination by Executive with Good Reason. Executive may terminate his employment with Good Reason by providing the Company thirty (30) days’ written notice setting forth in reasonable specificity the event that constitutes Good Reason, which written notice, to be effective, must be provided to the Company within sixty (60) days of the occurrence of such event. During such thirty (30) day notice period, the Company shall have a cure right (if curable), and if not cured within such period, Executive’s termination will be effective upon the expiration of such cure period, and Executive shall be entitled to the same payments and benefits as provided in Section 7(e) hereof for a termination by the Company without Cause, subject to the same conditions on payment and benefits as described in Section 7(e) hereof; provided that, if Executive terminates his employment with Good Reason on the basis of clause (ii) of the definition of “Good Reason,” then the payments required by Section 7(e)(iv) shall be in an amount equal to the Executive’s Base Salary in effect immediately prior to the event constituting Good Reason. Following such termination of Executive’s employment by Executive with Good Reason, except as set forth in this Section 7(f), Executive shall have no further rights to any compensation or any other benefits under this Agreement. For the avoidance of doubt, Executive’s sole and exclusive remedy upon a termination of employment with Good Reason shall be receipt of the Severance Benefits.

(g) Termination by Executive without Good Reason. Executive may terminate his employment without Good Reason by providing the Company thirty (30) days’ written notice of such termination. In the event of a termination of employment by Executive under this Section 7(g), Executive shall be entitled only to the Accrued Obligations. In the event of termination of Executive’s employment under this Section 7(g), the Company may, in its sole and absolute discretion, by written notice accelerate such date of termination without changing the characterization of such termination as a termination by Executive without Good Reason. Following such termination of Executive’s employment by Executive without Good Reason, except as set forth in this Section 7(g), Executive shall have no further rights to any compensation or any other benefits under this Agreement.

(h) Release. Notwithstanding any provision herein to the contrary, the payment of any amount or provision of any benefit pursuant to subsection (d) or (e) of this Section 7 (collectively, the “Severance Benefits”), other than the Accrued Obligations, shall be conditioned upon Executive’s execution, delivery to the Company, and non-revocation of the Release of Claims (and the expiration of any revocation period contained in such Release of Claims) within sixty (60) days following the date of Executive’s termination of employment hereunder (the “Release Execution Period”). If Executive fails to execute the Release of Claims in such a timely manner so as to permit any revocation period to expire prior to the end of such sixty (60) day period, or timely revokes his acceptance of such release following its execution, Executive shall not be entitled to any of the Severance Benefits. No portion of the Severance Benefits (other than Accrued Obligations) shall be paid until the Release has become effective and all amounts shall commence to be paid on the first regular payroll date of the Company after the Release has become effective; provided, that, if the Release Execution Period overlaps two calendar years, the first payment shall not be made sooner than the first day of the second year, and shall include any missed payments.

Section 8. Certain Payments.

In the event that (i) Executive is entitled to receive any payment, benefit or distribution of any type to or for the benefit of Executive, whether paid or payable, provided or to be provided, or distributed or distributable, pursuant to the terms of this Agreement or otherwise (collectively, the “Payments”), and (ii) the net after-tax amount of such Payments, after Executive has paid all taxes due thereon (including, without limitation, taxes due under Section 4999 of the Code) is less than the net after-tax amount of all such Payments otherwise due to Executive in the aggregate, if such Payments were reduced to an amount equal to 2.99 times Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code), then the aggregate amount of such Payments payable to Executive shall be reduced to an amount that will equal 2.99 times Executive’s base amount. To the extent such aggregate parachute payment amounts are required to be so reduced, the parachute payment amounts due to Executive (but no non-parachute payment amounts) shall be reduced in the following order: (i) the parachute payments that are payable in cash shall be reduced (if necessary, to zero) with amounts that are payable last reduced first; (ii) payments and benefits due in respect of any equity, valued at full value (rather than accelerated value), with the highest values reduced first (as such values are determined under Treasury Regulation Section 1.280G-1, Q&A 24); and (iii) all other non-cash benefits not otherwise described in clause (ii) of this Section 8 reduced last.

Section 9. Restrictive Covenants

(a) General. Executive acknowledges and recognizes the highly competitive nature of the business of the Company Group, that access to Confidential Information renders Executive special and unique within the industry of the Company Group, and that Executive will have the opportunity to develop substantial relationships with existing and prospective clients, accounts, customers, consultants, contractors, investors, and strategic partners of the Company Group during the course of and as a result of Executive’s employment with the Company. In light of the foregoing, as a condition of Executive’s employment by the Company, and in consideration of Executive’s employment hereunder and the compensation and benefits provided herein, Executive acknowledges and agrees to the covenants contained in this Section 9. Executive further recognizes and acknowledges that the restrictions and limitations set forth in this Section 9 are reasonable and valid in geographical and temporal scope and in all other respects and are essential to protect the value of the business and assets of the Company Group.

(b) Confidential Information.

(i) Executive acknowledges that, during the Term of Employment, Executive will have access to information about the Company Group and that his employment with the Company shall bring him into close contact with confidential and proprietary information of the Company Group. In recognition of the foregoing, Executive agrees, at all times during the Term of Employment and thereafter, to hold in confidence, and not to use, except for the benefit of the Company Group, or to disclose to any Person without written authorization of the Company, any Confidential Information.

(ii) Nothing in this Agreement shall prohibit or impede Executive from communicating, cooperating or filing a complaint with any U.S. federal, state or local governmental or law enforcement branch, agency or entity (collectively, a “Governmental Entity”) with respect to possible violations of any U.S. federal, state or local law or regulation, or otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or regulation, provided that in each case such communications and disclosures are consistent with applicable law. Executive understands and acknowledges that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made (i) in confidence to a Federal, State, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Executive understands and acknowledges further that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Moreover, Executive is not required to give prior notice to (or get prior authorization from) the Company regarding any such communication or disclosure. Notwithstanding the foregoing, under no circumstance will Executive be authorized to disclose any information covered by attorney-client privilege or attorney work product of any member of the Company Group without prior written consent of Company’s General Counsel or other officer designated by the Company.

(i) Executive agrees that he will, without additional compensation, promptly make full written disclosure to the Company, and will hold in trust for the sole right and benefit of the Company all developments, original works of authorship, inventions, concepts, know-how, improvements, trade secrets, and similar proprietary rights, whether or not patentable or registrable under copyright or similar laws, which Executive may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice, during the Term of Employment, whether or not during regular working hours, provided they either (i) relate at the time of conception or reduction to practice of the invention to the business of any member of the Company Group, or actual or demonstrably anticipated research or development of any member of the Company Group; (ii) result from or relate to any work performed for any member of the Company Group; or (iii) are developed through the use of equipment, supplies, or facilities of any member of the Company Group, or any Confidential Information, or in consultation with personnel of any member of the Company Group (collectively referred to as “Developments”). Executive further acknowledges that all Developments made by Executive (solely or jointly with others) within the scope of and during the Term of Employment are “works made for hire” (to the greatest extent permitted by applicable law) for which Executive is, in part, compensated by his Base Salary, unless regulated otherwise by law, but that, in the event any such Development is deemed not to be a work made for hire, Executive hereby assigns to the Company, or its designee, all Executive’s right, title, and interest throughout the world in and to any such Development.

(ii) Executive agrees to assist the Company, or its designee, at the Company’s expense, in every way to secure the rights of the Company Group in the Developments and any copyrights, patents, trademarks, service marks, database rights, domain names, mask work rights, moral rights, and other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, recordations, and all other instruments that the Company shall deem necessary in order to apply for, obtain, maintain, and transfer such rights and in order to assign and convey to the Company Group the sole and exclusive right, title, and interest in and to such Developments, and any intellectual property and other proprietary rights relating thereto. Executive further agrees that his obligation to execute or cause to be executed, when it is in Executive’s power to do so, any such instrument or papers shall continue after the termination of the Term of Employment until the expiration of the last such intellectual property right to expire in any country of the world; provided, however, that the Company shall reimburse Executive for his reasonable expenses incurred in connection with carrying out the foregoing obligation. If the Company is unable because of Executive’s mental or physical incapacity or unavailability for any other reason to secure Executive’s signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Developments or original works of authorship assigned to the Company as above, then Executive hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Executive’s agent and attorney in fact to act for and in Executive’s behalf and stead to execute and file any such applications or records and to do all other lawfully permitted acts to further the application for, prosecution, issuance, maintenance, and transfer of letters patent or registrations thereon with the same legal force and effect as if originally executed by me. Executive hereby waives and irrevocably quitclaims to the Company any and all claims, of any nature whatsoever, that Executive now or hereafter have for past, present, or future infringement of any and all proprietary rights assigned to the Company.

Notwithstanding the foregoing, (A) Executive may purchase or otherwise own up to (but not more than) 2.00% of any class of securities of any enterprise (but without otherwise participating in the activities of such enterprise) if such securities are listed on any national or regional securities exchange or have been registered under Section 12(g) of the Securities Exchange Act of 1934 and (B) nothing herein shall prevent Executive from directly or indirectly

engaging in, having any equity interest in, or managing, providing services to or otherwise operating any Person that primarily engages in an upstream oil and gas business (i.e., the exploration and production of oil and gas) or a midstream oil and gas business (i.e., gathering, processing, treating, transportation or distribution of oil and gas), in each case so long as less than 5% of the revenues of such business are derived from the provision of services or equipment related to contract compression to any third Persons.

(e) Non-Interference. During the Term of Employment and the Post-Termination Restricted Period, Executive shall not, directly or indirectly for his own account or for the account of any other Person, engage in Interfering Activities.

Each of the rights enumerated in this Section 9 shall be independent of the others and shall be in addition to and not in lieu of any other rights and remedies available to the Company Group at law or in equity. If any of the provisions of this Section 9 or any part of any of them is hereafter construed or adjudicated to be invalid or unenforceable, the same shall not affect the remainder of this Section 9, which shall be given full effect without regard to the invalid portions. If any of the covenants contained herein are held to be invalid or unenforceable because of the duration of such provisions or the area or scope covered thereby, each of the Company and Executive agree that the court making such determination shall have the power to reduce the duration, scope, and/or area of such provision to the maximum and/or broadest duration, scope, and/or area permissible by law, and in its reduced form said provision shall then be enforceable.

(i) Injunctive Relief. Executive expressly acknowledges that any breach or threatened breach of any of the terms and/or conditions set forth in this Section 9 may result in substantial, continuing, and irreparable injury to the members of the Company Group. Therefore, Executive hereby agrees that, in addition to any other remedy that may be available to the Company, any member of the Company Group shall be entitled to seek injunctive relief, specific performance, or other equitable relief by a court of appropriate jurisdiction in the event of any breach or threatened breach of the terms of this Section 9. Notwithstanding any other provision to the contrary, Executive acknowledges and agrees that the Post-Termination Restricted Period shall be tolled during any period of violation of any of the covenants in this Section 9.

(j) Other Covenants. Notwithstanding anything contained in this Agreement to the contrary, in the event that Executive is subject to similar restrictive covenants pursuant to any other agreement with any member of the Company Group, including, without limitation, under the Equity Documents (“Other Covenants”), the covenants contained in this Agreement shall be in addition to, and not in lieu of, any such Other Covenants, and enforcement by the Company of the covenants contained in this Agreement shall not preclude the applicable member of the Company Group from enforcing such Other Covenants in accordance with their terms.

Section 10. Representations and Warranties of Executive.

(d) Executive has not been terminated from any prior employer or service recipient, or otherwise disciplined in connection any such relationship, in connection with, or as a result of, any claim of workplace sexual harassment or sex or gender discrimination, and to Executive’s knowledge, Executive has not been the subject of any investigation, formal allegation, civil or criminal complaint, charge, or settlement regarding workplace sexual harassment or sex or gender discrimination.

Section 11. Taxes.

The Company may withhold from any payments made under this Agreement all applicable taxes, including but not limited to income, employment, and social insurance taxes, as shall be required by law. Executive acknowledges and represents that the Company has not provided any tax advice to him in connection with this Agreement and that he has been advised by the Company to seek tax advice from his own tax advisors regarding this Agreement and payments that may be made to him pursuant to this Agreement, including specifically, the application of the provisions of Section 409A of the Code to such payments.

Section 12. Set Off; Mitigation.

The Company’s obligation to pay Executive the amounts provided and to make the arrangements provided hereunder shall be subject to set-off, counterclaim, or recoupment of amounts owed by Executive to the Company or its affiliates; provided, however, that to the extent any amount so subject to set-off, counterclaim, or recoupment is payable in installments hereunder, such set-off, counterclaim, or recoupment shall not modify the applicable payment date of any installment, and to the extent an obligation cannot be satisfied by reduction of a single installment payment, any portion not satisfied shall remain an outstanding obligation of Executive and shall be applied to the next installment only at such time the installment is otherwise payable pursuant to the specified payment schedule. Executive shall not be required to mitigate the amount of any payment provided pursuant to this Agreement by seeking other employment or otherwise, and except as provided in Section 7(e)(v) hereof, the amount of any payment provided for pursuant to this Agreement shall not be reduced by any compensation earned as a result of Executive’s other employment or otherwise.

Section 13. Additional Section 409A Provisions.

Notwithstanding any provision in this Agreement to the contrary:

(a) Any payment otherwise required to be made hereunder to Executive at any date as a result of the termination of Executive’s employment shall be delayed for such period of time as may be necessary to meet the requirements of Section 409A(a)(2)(B)(i) of the Code (the “Delay Period”). On the first business day following the expiration of the Delay Period, Executive shall be paid, in a single cash lump sum, an amount equal to the aggregate amount of all payments delayed pursuant to the preceding sentence, and any remaining payments not so delayed shall continue to be paid pursuant to the payment schedule set forth herein.

(b) Each payment in a series of payments hereunder shall be deemed to be a separate payment for purposes of Section 409A of the Code.

(c) Notwithstanding anything herein to the contrary, the payment (or commencement of a series of payments) hereunder of any nonqualified deferred compensation (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as Executive has also undergone a “separation from service” as defined in Treas. Reg. 1.409A-1(h), at which time such nonqualified deferred compensation (calculated as of the date of Executive’s termination of employment hereunder) shall be paid (or commence to be paid) to Executive on the schedule set forth in Section 7 as if Executive had undergone such termination of employment (under the same circumstances) on the date of his ultimate “separation from service.”

(d) To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made by the Company no later than the last day of the taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, however, that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect.

(e) While the payments and benefits provided hereunder are intended to be structured in a manner to avoid the implication of any penalty taxes under Section 409A of the Code, in no event whatsoever shall any member of the Company Group be liable for any additional tax, interest, or penalties that may be imposed on Executive as a result of Section 409A of the Code or any damages for failing to comply with Section 409A of the Code (other than for withholding obligations or other obligations applicable to employers, if any, under Section 409A of the Code).

Section 14. Successors and Assigns; No Third-Party Beneficiaries.

(a) The Company. This Agreement shall inure to the benefit of the Company and its respective successors and assigns. Neither this Agreement nor any of the rights, obligations, or interests arising hereunder may be assigned by the Company to a Person (other than another member of the Company Group, or its or their respective successors) without Executive’s prior written consent (which shall not be unreasonably withheld, delayed, or conditioned); provided, however, that in the event of a sale of all or substantially all of the assets of the Company or any direct or indirect division or subsidiary thereof to which Executive’s employment primarily relates, the Company may provide that this Agreement will be assigned to, and assumed by, the acquiror of such assets, division or subsidiary, as applicable, without Executive’s consent.

(b) Executive.

(c) No Third-Party Beneficiaries. Except as otherwise set forth in Section 7(c) or Section 14(b) hereof, nothing expressed or referred to in this Agreement will be construed to give any Person other than the Company, the other members of the Company Group, and Executive any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement.

No waiver by either of the parties hereto of their rights hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences or transactions hereunder unless such waiver specifically states that it is to be construed as a continuing waiver.

Section 16. Severability.

If any covenants or such other provisions of this Agreement are found to be invalid or unenforceable by a final determination of a court of competent jurisdiction, (a) the remaining terms and provisions hereof shall be unimpaired, and (b) the invalid or unenforceable term or provision hereof shall be deemed replaced by a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision hereof.
