 6. Property. Both during the Term of Employee’s employment and thereafter, the
Employee shall not remove from the Company’s offices or premises any Company documents, records, notebooks, files, correspondence, reports, memoranda and similar materials or property of any kind unless necessary in accordance with the duties

Employee’s control, whether prepared by the Employee or by others. 
 7. Termination. 

7.1 For Cause. The Company, by action of the Board, may terminate this Agreement and the Employee’s employment for Cause (as
defined below) on delivery to the Employee of a Notice of Termination (as defined in Section 9.1 below). On such termination for Cause, the Employee shall be entitled only to the Employee’s Base Salary through the date of such
termination, and shall not be entitled to any other compensation, including, without limitation, any severance compensation. Without limitation of the foregoing, on termination pursuant to this Section 7.1, the Employee shall forfeit:
(a) Employee’s Bonus under Section 4.2 for the year in which such termination occurs; and (b) all outstanding but unvested Options and rights relating to capital stock of the Company and all RSUs and shares of the
Company’s Restricted Stock issued to the Employee that as of the termination date are still unvested and subject to restrictions on transfer. 
 7.2 Without Cause. The employment of the Employee may be terminated without Cause at any time by the Company on delivery to the Employee of a written Notice of Termination (as defined in
Section 9.1). In the event of such a termination without Cause pursuant to this Section 7.2 that constitutes Employee’s Separation From Service (as defined in Section 9.3), then, subject to the
Employee’s execution and non-revocation of a general release of all claims against the Company and its affiliates within sixty (60) days, or such shorter period of time specified by the Company, following the Date of Termination (as
defined in Section 9.2), the Company shall, in lieu of any payments under Section 4.1 and 4.2 for the remainder of the Term, pay to the Employee an amount equal to the lesser of: (a) the Employee’s Base
Salary for a period of one (1) year from the Date of Termination, and (b) the Employee’s Base Salary for the remainder of the Term (“Severance”). The Severance shall be paid in accordance with the Company’s
normal payroll practices and is subject to all withholding requirements under applicable law, with the first such payment to be paid on the sixtieth (60th) day following the Date of Termination inclusive of any installments that would have been paid had such
continuation payments commenced on the Date of Termination. In addition, the Employee shall be entitled to the pro-rated target Bonus available to the Employee under Section 4.2 for the year in which the termination occurs, taking into
account the bonus categories and weighting under the Company’s bonus plan and the Company’s and Employee’s achievement thereunder as of the Date of Termination. Further, the Company will pay as incurred the Employee’s expenses,
up to Fifteen Thousand Dollars ($15,000), associated with career counseling and resume development. The Company shall also pay to the Employee an amount equal to the Company’s portion (but not the Employee’s portion) of the cost of
medical, dental and vision plan insurance for Employee,

Employee’s spouse and Employee’s children at the rate in effect on the Date of Termination for a period of one (1) year from the Date of Termination (the “Health Insurance
Benefit”). Notwithstanding the previous sentence, with regard to such continuation coverage, if the Company determines in its sole discretion that it cannot provide the foregoing benefit without potentially violating applicable law or
potentially incurring penalties, excise taxes and fees pursuant to the Internal Revenue Code of 1986, as amended (the “Code”) and the Department of Treasury regulations promulgated thereunder (including, without limitation,
Section 2716 of the Public Health Service Act), the Health Insurance Benefit shall terminate and the Employee shall not be eligible to receive any further benefits related to the Health Insurance Benefit other than as otherwise required by
applicable law. In addition, on termination of the Employee under this Section 7.2, all of the Employee’s outstanding but unvested Options and rights relating to capital stock of the Company shall immediately vest and become
exercisable, and all RSUs and shares of the Company’s Restricted Stock issued to the Employee shall immediately vest and become unrestricted and freely transferable. The exercisability of any such Options and rights shall be extended to the
earlier of (i) the expiration of the term of such Options and rights or (ii) the first (1st) anniversary of the Date of Termination. The Employee acknowledges that extending the exercisability of any incentive stock options pursuant to this Section 7.2 or Sections 7.3 or
7.4 below, could cause such option to lose its tax-qualified status if it is an incentive stock option under the Code and agrees that the Company shall have no obligation to compensate the Employee for any additional taxes he incurs as a
result. 
 7.3 Termination on Disability. If during the Term the Employee should fail to perform
Employee’s duties hereunder on account of Disability, the Company shall have the right, on written Notice of Termination delivered to the Employee, to terminate the Employee’s employment under this Agreement. During the period that the
Employee shall have been incapacitated due to physical or mental illness, the Employee shall continue to receive the full Base Salary provided for in Section 4.1 hereof at the rate then in effect until the Date of Termination pursuant to
this Section 7.3. In the event of Employee’s termination for Disability pursuant to this Section 7.3 that constitutes Employee’s Separation from Service, then on the Date of Termination, the Company shall, in lieu
of any payments under Sections 4.1 and 4.2 for the remainder of the Term, pay to the Employee the payments and other benefits applicable to termination without Cause set forth in Section 7.2 hereof, other than those related
to career counseling and resume development. The Company shall also pay the Health Insurance Benefit. Notwithstanding the previous sentence, with regard to such continuation coverage, if the Company determines in its sole discretion that it cannot
provide the foregoing benefit without potentially violating applicable law or potentially incurring penalties, excise taxes and fees pursuant to the Code and the Department of Treasury regulations promulgated thereunder (including, without
limitation, Section 2716 of the Public Health Service Act), the Health Insurance Benefit shall terminate and the Employee shall not be eligible to receive any further benefits related to the Health Insurance Benefit other than as otherwise
required by applicable law. In addition, on such termination, all of the Employee’s outstanding but unvested Options and rights relating to capital stock of the Company shall immediately vest and become exercisable, and all RSUs and shares of
the Company’s Restricted Stock issued to the Employee shall immediately vest and become unrestricted and freely transferable. The exercisability of any such Options and rights shall be extended to the earlier of (a) the expiration of the
term of such Options or rights or (b) the first
(1st) anniversary of the Employee’s termination.

Term, the employment of the Employee shall thereupon terminate. On the Date of Termination pursuant to this Section 7.4, the Company shall pay, in lieu of any payments under Sections 4.1 and 4.2 for the remainder of the
Term, to the Employee’s estate the payments and other benefits applicable to termination without Cause set forth in Section 7.2 hereof, other than those related to career counseling, resume development and the Health Insurance
Benefit. In addition, on termination of the Employee under this Section 7.4, all of the Employee’s outstanding but unvested Options and rights relating to capital stock of the Company shall immediately vest and become exercisable,
and all RSUs and shares of the Company’s Restricted Stock issued to the Employee shall immediately vest and become unrestricted and freely transferable. The exercisability of any such Options and rights shall be extended to the earlier of
(a) the expiration of the term of such Options or rights or (b) the first (1st) anniversary of the Employee’s termination. The provisions of this Section 7.4 shall not affect the entitlements of the Employee’s heirs, executors, administrators, legatees,
beneficiaries or assigns under any employee benefit plan, fund or program of the Company. 
 7.5 No Limitation on
Company’s Right to Terminate. Any other provision in this Agreement to the contrary notwithstanding, the Company shall have the right, in its absolute discretion, to terminate this Agreement and the Employee’s employment hereunder at
any time in accordance with the foregoing provisions of this Section 7, it being the intent and purpose of the foregoing provisions of this Section 7 only to set forth the consequences of termination with respect to severance
or other compensation payable to the Employee on termination in the circumstances indicated. 
 8. Termination by
Employee. The Employee may terminate his employment hereunder on written Notice of Termination delivered to the Company setting forth the effective Date of Termination. If the Employee terminates his employment hereunder, he shall be entitled to

to this Section 8, the Employee shall forfeit: (a) his Bonus under Section 4.2 for the year in which such termination occurs; and (b) all outstanding but unvested Options and rights relating to capital stock of the

the provisions of Section 409A, any such reimbursements payable to Employee pursuant to this Agreement shall be paid to Employee no later than December 31 of the year following the year in which the expense was incurred, the amount of

following restrictions may limit the Employee’s ability to earn a livelihood in a business which, directly or indirectly, compete with the Company. However, the Employee agrees that the Employee will receive sufficient consideration and other
benefits as an Employee of the Company to clearly justify such restrictions which, in any event, given the Employee’s skills and ability will not prevent the Employee from earning a living. The Employee acknowledges that all restrictions
contained in this Section 11 are reasonable and valid as to time, geographical area, and scope of activity to be restrained for the adequate protection of the legitimate business interests and goodwill of the Corporation and are no
broader than is necessary to protect such interests and goodwill. In consideration of the provisions hereof, for the Restricted Period (as defined below), the Employee will not, except as specifically provided below, anywhere in any county of any

purpose of any event occurring on or after the Date of Termination, shall mean the Company’s operations as existing on the Date of Termination (the “Restricted Territory”), directly or indirectly, acting individually or as the
owner, shareholder, partner or management employee of any entity: (a) engage in the operation of a solid waste collection, transporting or disposal business, transfer facility, recycling facility, materials recovery facility or solid waste
landfill; or (b) enter the employ as a manager of, or render any personal services to or for the benefit of, or assist in or facilitate the solicitation of customers for, or receive remuneration in the form of management salary, commissions or
otherwise from, any business engaged in such activities in such counties; or (c) receive or purchase a financial interest in, make a loan to, or make a gift in support of, any such business in any capacity, including without limitation, as a
sole proprietor, partner, shareholder, officer, director, principal agent or trustee; provided, however, that the Employee may own, directly or indirectly, solely as an investment, securities of any business traded on any national
securities exchange or quoted on any NASDAQ market, provided the Employee is not a controlling person of, or a member of a group which controls, such business and further provided that the Employee does not, in the aggregate,
directly or indirectly, own Two Percent (2%) or more of any class of securities of such business. The term “Restricted Period” shall mean the period commencing on the Effective Date and ending on the first anniversary of the
Date of Termination.

provision of this Section 11 is invalid or unenforceable, the parties agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration or area of the term or provision, to
delete specified words or phrases or to replace any invalid or unenforceable term or provision with 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, and this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment may be appealed. 
 12. Indemnification. As an officer and agent of the Company, the Employee shall be fully indemnified by the Company to the fullest extent permitted by applicable law in connection with his
employment hereunder. 
 13. Limitation on Payments. Notwithstanding any other provisions of this Agreement, in the event
that any payment or benefit received or to be received by the Employee, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement (all such payments and benefits being hereinafter referred to as the “Total
Payments”), would be subject (in whole or part), to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of
Section 280G of the Code in such other plan, arrangement or agreement, the Total Payments shall be reduced as set forth herein, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if

each year in which the foregoing shall be paid to the Employee (based on the rate in effect for such year as set forth in the Code as in effect at the time of the first payment of the foregoing) on such reduced Total Payments and after taking into
account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (b) the net amount of such Total Payments without such reduction (but after subtracting the amount of
all federal, state and local income and employment taxes payable with respect to the foregoing calculated at the maximum marginal income tax rate for each year in which the foregoing shall be paid to the Employee (based on the rate in effect for
such year as set forth in the Code as in effect at the time of the first payment of the foregoing) on such Total Payments and the amount of Excise Tax to which the Employee would be subject in respect of such unreduced Total Payments and after
taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments). The Total Payments shall be reduced by the Company in its reasonable discretion in the following order:
(i) reduction of any cash severance payments otherwise payable to the Employee that are exempt from

Section 409A, (ii) reduction of any other cash payments or benefits otherwise payable to the Employee that are exempt from Section 409A, but excluding any payment attributable to
the acceleration of vesting or payment with respect to any equity award that is exempt from Section 409A, (iii) reduction of any other payments or benefits otherwise payable to the Employee on a pro-rata basis or such other manner that
complies with Section 409A, but excluding any payment attributable to the acceleration of vesting and payment with respect to any equity award that is exempt from Section 409A, and (iv) reduction of any payments attributable to the
acceleration of vesting or payment with respect to any equity award that is exempt from Section 409A. For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (A) no portion of the
Total Payments the receipt or enjoyment of which the Employee shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken into account,
(B) no portion of the Total Payments shall be taken into account which, in the opinion of independent counsel, consultants or advisors of nationally recognized standing (“Independent Advisors”) selected by the Company, does not
constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken
into account which, in the opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the Base Amount (as defined in
Section 280G(b)(3) of the Code) allocable to such reasonable compensation, and (C) the value of any non cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Independent Advisors in
accordance with the principles of Sections 280G(d)(3) and (4) of the Code. 
 14. Survival of Provisions. The
obligations of the Company under Section 12 of this Agreement, and of the Employee under Sections 5, 6 and 11 of this Agreement, shall survive both the termination of the Employee’s employment and this
Agreement. 
 15. No Duty to Mitigate; No Offset. The Employee shall not be required to mitigate damages or the amount of
any payment contemplated by this Agreement, nor shall any such payment be reduced by any earnings that the Employee may receive from any other sources or offset against any other payments made to him or required to be made to him pursuant to this
Agreement; provided, however, in the event that the Employee becomes entitled to or receives any severance, separation, notice or termination payments on account of his or her employment or termination of employment with the Company,
including, for example, any payments required to be paid to the Employee under any Federal, State or local law or pursuant to any agreement (except unemployment benefits payable in accordance with State or Federal law and payment for any unused but
accrued vacation), his or her severance benefits and payments payable under this Agreement shall be reduced by the amount of any such payments paid or payable. Notice and payments in lieu of notice of termination of employment pursuant to the
requirements of the Worker Adjustment and Retraining Notification Act and/or any similar federal, state or local law (collectively referred to as “WARN laws”) are subject to this Section. If the Employee is entitled to receive any
payments or benefits from the Company pursuant to WARN laws, then the severance benefits and payments payable under this Agreement shall be reduced by any and all such payments made or such benefits provided by the Company to such employee. If any
Employee is entitled to receive notice of termination from the Company pursuant to WARN laws, then the Severance payable under this Agreement shall be reduced by an amount equal to the amount of salary paid and health benefits provided during the
notice period provided to the employee by the Company.

 16. Assignment; Binding Agreement. The Company may assign this Agreement to any
parent, subsidiary, affiliate or successor of the Company. This Agreement is not assignable by the Employee and is binding on him and his executors and other legal representatives. This Agreement shall bind the Company and its successors and assigns
and inure to the benefit of the Employee and his heirs, executors, administrators, personal representatives, legatees or devisees. The Company shall assign this Agreement to any entity that acquires its assets or business.

time specify by written notice. 
 18. Entire Agreement; Amendments. This Agreement contains the entire agreement of the
parties relating to the Employee’s employment and supersedes all oral or written prior discussions, agreements and understandings of every nature between them, except for that certain Indemnification Agreement, dated on or about the date
hereof, by and between the Company and the Employee, which shall remain in full force and effect. This Agreement may not be changed except by an agreement in writing signed by the Company and the Employee. 

19. Waiver. The waiver of a breach of any provision of this Agreement shall not operate as or be construed to be a waiver of any
other provision or subsequent breach of this Agreement. 
 20. Governing Law and Jurisdictional Agreement. This Agreement
shall be governed by and construed and enforced in accordance with the laws of the State of Texas. The parties irrevocably and unconditionally submit to the jurisdiction and venue of any court, federal or state, situated within Harris County, Texas,

21. Severability. In case any one or more of the provisions contained in this Agreement is, for any reason, held invalid in any
respect, such invalidity shall not affect the validity of any other provision of this Agreement, and such provision shall be deemed modified to the extent necessary to make it enforceable.

 22. Enforcement. It is agreed that it is impossible to measure fully, in money, the
damage which will accrue to the Company in the event of a breach or threatened breach of Sections 5, 6, or 11 of this Agreement, and, in any action or proceeding to enforce the provisions of Sections 5, 6 or
11 hereof, the Employee waives the claim or defense that the Company has an adequate remedy at law and will not assert the claim or defense that such a remedy at law exists. The Company is entitled to injunctive relief to enforce the
provisions of such Sections as well as any and all other remedies available to it at law or in equity without the posting of any bond. The Employee agrees that if the Employee breaches any provision of Section 11, the Company may recover
as partial damages all profits realized by the Employee at any time prior to such recovery on the exercise, grant or issuance of any Option, Restricted Stock, RSU or other equity incentive and the subsequent sale of any shares of the Company’s
Common Stock obtained through such exercise, grant or issuance, and may also cancel all outstanding such Options, Restricted Stock, RSUs or other equity incentives. 
 23. Withholding. All compensation payable to the Employee is subject to all withholding requirements under applicable law. 

24. Counterparts. This Agreement may be executed in one or more facsimile or original counterparts, each of which shall be deemed
an original and both of which together shall constitute one and the same instrument.
