 NOW,
THEREFORE, in consideration of the foregoing Recitals, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the
parties hereby agree as follows: 
 1. Employment: Position and Duties. The Company agrees to employ Employee, and Employee agrees to
be employed by the Company, upon the terms and subject to the conditions of this Agreement. Employee shall be employed by the Company as the Chief Executive Officer. In this capacity, Employee agrees to devote his full time, energy and skill to the
faithful performance of his duties herein, and shall perform the duties and carry out the responsibilities assigned to him to the best of Employee’s ability and in a diligent, businesslike and efficient manner. Employee will not engage in any

charitable or community activities; (ii) providing advice, assistance and counsel to Controlled Affiliates (as defined below) on a basis consistent with past practices; and (iii) managing Employee’s and his family’s personal
investments; provided, that any such activities do not materially interfere with the performance of Employee’s duties and responsibilities hereunder. Employee’s duties shall include those duties customarily performed by an officer
in Employee’s position and such additional duties as may be assigned from time to time by the Board of Directors (the “Board”) of the Company. Employee shall comply with any policies and procedures established for Company
employees, including, without limitation, those policies and procedures contained in the Company’s employee handbook previously delivered to Employee. To the extent there is any conflict between those policies and this Agreement, this Agreement
shall govern. Employee shall travel to such places in the United States and elsewhere as the Board directs from time to time as needed. 

2. Term of Employment. The Company shall employ Employee, and Employee shall serve the Company, beginning on the Effective Date and
continuing until this Agreement is terminated in accordance with its terms (the “Employment Period”). Notwithstanding anything to the contrary contained herein, either Employee or the Company may terminate Employee’s employment
with the Company for any reason, at any time, upon not less than thirty (30) days’ 

 
prior notice; provided that no prior notice shall be required from the Company if Employee is terminated by the Company for Cause (as defined below). Upon the termination of Employee’s
employment with the Company, the Company shall not have any further obligation or liability to pay any compensation or benefits to Employee, except as set forth in Section 4 of this Agreement to the extent such termination occurs during
the Employment Period. 
 3. Compensation. During the Employment Period, Employee shall be compensated by the Company for his
services as follows: 
 (a) Base Salary. Employee shall be paid an annual base salary (the “Annual Base Salary”) of
$300,000 in accordance with the Company’s normal payroll procedures. Increases in Employee’s Annual Base Salary shall be as approved by the Board or its Compensation Committee. 

(b) Benefits. Employee shall have the right, on the same basis as other members of senior management of the Company, to participate in
and to receive benefits under the Company’s executive and employee benefit plans, 401K plan, paid holidays, insurance programs and/or indemnification agreements, as may be in effect from time to time, subject to any applicable waiting periods
and other restrictions. In addition, Employee shall be entitled to health insurance reasonably similar to the most recent health insurance received at Employee’s previous employer at a monthly cost of $524 to Employee. Employee shall also be
entitled to $1,000,000 of life insurance reasonably similar to the most recent life insurance received at Employee’s previous company. Employee shall be entitled to paid time-off in accordance with the
Company’s policies as such policies may exist from time to time. 
 (c) Signing and EBITDA Bonus: Employee shall be eligible to
receive a one-time cash bonus of $75,000 (the “Signing Bonus”), such Signing Bonus to be earned and payable on completion of Employee’s first day of employment; provided, however, that if
Employee resigns from the Company for any reason or is terminated by the Company for Cause as defined below on or prior to December 31, 2019, then Employee shall be required to repay the net amount of the Signing Bonus to the Company within ten
(10) business days following such resignation or termination. Employee shall be eligible to receive a one-time cash bonus of $25,000, such bonus to become earned and payable in July of 2019 (the
“2019 EBITDA Bonus”) if the Company has achieved its January—June 2019 budgeted EBTIDA performance. The Signing Bonus and the 2019 EBITDA Bonus will be subject to all applicable taxes and withholding and will be paid in accordance
with the payment practices of the Company then in effect on the next payroll date occurring more than five (5) business days after such bonus becomes earned and payable.

the applicable bonus period. The receipt and amount of Employee’s bonus shall be subject to Employee (i) achieving personal and Company goals as determined by the Board of Managers (the “Board”) of the Company and parent entity
of the Company (“Holdco”), and (ii) being employed by the Company on the date of payment of such bonus. Each Annual Bonus shall be finally determined by the Board in its sole discretion after taking into account Company and individual
performance achievements. Each Annual Bonus will be paid following the completion of the Company’s fiscal year audit for the applicable twelve (12) month period. A portion of each Annual Bonus may be deferred in accordance with the
Company’s standard compensation practices. Employee’s salary and each Annual Bonus will be subject to all applicable taxes and withholding and will be paid in accordance with the payment practices of the Company then in effect. 

(e) Management Incentive Equity Pool: Following completion of three (3) months of employment, Employee will be eligible to receive
incentive equity (the “Equity Grant”) in the form of incentive units that represent 3% of the appreciation in the value of Holdco following the date of issuance of the Equity Grant. Any Equity Grant will be subject to the terms and
conditions of the award agreement pursuant to which such Equity Grant will be granted (the “Award Agreement”) (including, without limitation, terms relating to the manner, time and rate of vesting of the Equity Grant) and other documents
to be determined and delivered by the Company to Employee.

Employee’s employment, unless other arrangements have been made.

reimbursement for business expenses incurred by Employee in the normal and ordinary course of his employment by the Company pursuant to the Company’s standard business expense reimbursement policies and procedures, which policies and procedures
shall be administered in compliance with applicable federal law. Employee shall provide the Company with documentation evidencing all requests for reimbursement of business expenses.

than (A) for Cause, or (B) by reason of his death or Disability: 
 (i) continued payment of Employee’s Annual Base Salary as
in effect on the date of the termination of Employee’s employment, less applicable withholding, in accordance with the Company’s normal payroll procedures, ending on the earlier of: (A) twelve (12) months following the termination of

of Employee’s employment, and (B) the date Employee has secured health benefits through another organization’s benefits program; provided, however, that Employee shall not be entitled to reimbursement of such portion of the
premium for COBRA coverage if such reimbursement is then impermissible under applicable law or would result in a penalty or additional tax upon Employee or the Company (aside from standard taxes applicable to the payment of wages). 

  
 - 4 - 

 Notwithstanding anything to the contrary herein, no payments shall be due under this
Section 4(b)(i) unless and until Employee shall have executed and not revoked, within thirty (30) days after Employee’s termination date (or such other longer period as required by applicable law’), a separation agreement and
general release and waiver of claims against the Company (other than (a) the payments and benefits contemplated by Section 4(a)(b) Employee’s right to receive COBRA continuation coverage in accordance with applicable law, and
(c) any rights to indemnification Employee has or may have as an officer or director of the Company or as an insured under any directors and officers liability insurance policy) in a form customarily used by the Company, and the execution and non-revocation of such general release and waiver shall be a condition to Employee’s rights under this Section 4(b) or (ii) if Employee breaches any restrictive covenants (including, without
limitation, the confidentiality, noncompetition, non-solicitation and non-hire covenants set forth in Sections 6 and 7 of this Agreement) applicable to
Employee pursuant to any written agreement that contains restrictive covenants applicable to Employee for the benefit of any Company Entity. If the cash severance hereunder is considered deferred compensation subject to Section 409A of the Code
and the period to consider and revoke the general release and waiver of claims spans two calendar years, the payments will begin in the second calendar year provided the release becomes effective. Any severance payments that would have been made
during the release consideration and revocation period will be accumulated and paid on the first installment payment date. 
 5. Section
409A of the Code. 
 (a) Except to the extent earlier payment is permitted by Section 409A of the Code and the regulations
promulgated thereunder, in the event that any amount due to Employee hereunder after the termination of his employment shall be considered to be deferred compensation pursuant to Section 409A of the Code, and it is determined that Employee is a
“specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, then the Company shall delay the payment of such amount for six (6) months after the termination of Employee’s employment (or until Employee’s
death, if earlier) or for such other amount of time as may be necessary to comply with the requirements of Section 409A(a)(2)(B)(i) of the Code. 

(b) This Agreement is intended to comply and shall be administered in a manner that is intended to comply with Section 409A of the Code
and the interpretative guidance thereunder or be exempt therefrom, including the exceptions for short-term deferrals and separation pay arrangements. This Agreement shall be construed and interpreted in accordance with such intent. In addition, each
payment shall be considered a separate payment for purposes of Section 409A of the Code, and any termination of employment under this Agreement shall mean a separation from service as defined in Section 409A of the Code and Treas. Reg.
§1.409A- l(h)(l)(ii) (or other similar or successor provision) for purposes of any amounts considered deferred compensation subject to Section 409A of the Code. To the extent any reimbursements or

 (b) During the Non-Compete Period, Employee shall
not (and shall cause his Controlled Affiliates not to), directly or indirectly, either for himself or through any other Person, (i) induce or attempt to induce any current or former (within the one (1) year period immediately preceding
such action) employee to leave the employ of any Company Entity, or in any way interfere with the relationship between such employee and any Company Entity, (ii) hire any current or former employee (within the previous one (1) year period)
of any Company Entity or (iii) call on, solicit or service any current customer or supplier or Prospective Customer for the sale of goods or services provided by a Competing Business, or contemplated by any Company Entity pursuant to a written plan
at any time while Employee provides services to the Company to be offered by, any Company Entity or induce or attempt to induce such Person to cease doing or decrease its business with any Company Entity, or in any way interfere with the
relationship between any customer, supplier, licensee, licensor or other business relation and any Company Entity (including making any negative statement or communication that is intended to or could reasonably be expected to disparage any Company
Entity). For the purpose of this Agreement, the term “Prospective Customer” shall mean any person or entity to which the Company has made a bid or proposal, which remains open, at any time in the one (1) year period immediately
preceding such action by Employee.

all respects (including, with respect to subject matter, time period and geographical area) and are necessary to protect the Company (including, the goodwill inherent therein) and that the Geographic Area reflects the scope of the businesses
conducted by the Company. 
 8. Enforceability and Breaches. 

(a) If any restrictive covenant contained herein is unenforceable with respect to the duration and geographic area of restriction of the
covenant, then the duration and geographic area of restriction shall be reduced to the maximum duration and geographic area of restriction deemed legal, valid and enforceable and that come closest to expressing the intention of the parties with
respect to the covenant, and the covenant shall be enforceable as so modified. The parties agree that a court with proper jurisdiction shall be allowed to reduce the restrictive covenants contained herein to the maximum duration and geographic area
of restriction deemed legal, valid and enforceable. 
 (b) Employee acknowledges and agrees that, in the event of a breach or threatened
breach by Employee of any of the provisions of this Agreement, monetary damages shall not constitute a sufficient remedy. Consequently, in the event of any such breach or threatened breach, the Company may (and shall be entitled to), in addition to
other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violations of the provisions of this
Agreement (including the extension of the Non-Compete Period by a period equal to the length of court proceedings necessary to stop such violation), in each case without the requirement of posting a bond or
proving actual damages.

1. Employment; Position and Duties. The Company agrees to employ Employee, and Employee agrees to be employed by the Company, upon the
terms and subject to the conditions of this Agreement. Employee shall be employed by the Company and shall report to the Chief Executive Officer of MCT Group Holdings, LLC (“Holdings”) and the Company (the “CEO”).
In this capacity, Employee agrees to devote his full time, energy and skill to the faithful performance of his duties herein, and shall perform the duties and carry out the responsibilities assigned to him to the best of Employee’s ability and
in a diligent, businesslike and efficient manner. Employee will not engage in any outside business activities that materially interfere with his obligations under this Agreement, and will not render services of a business, professional or commercial
