established long-term incentive plan, on such terms and conditions that are approved by the Board of Directors of Employer, with an annual target award ranging between 100% and 130% of Employee’s salary (prorated for 2008 based upon
Employee’s 2008 employment with Employer), as determined in the discretion of Employer’s Board of Directors. 
 4.05 During
Employee’s employment with Employer, Employer shall (a) provide Employee a company car allowance of $1,000 per month and (b) reimburse Employee’s reasonable and documented out of pocket expenses for company car maintenance,
repair and gas in accordance with the policies established by Employer from time to time. To the extent any amounts payable under the immediately preceding sentence are taxable to Employee, Employer shall pay Employee an additional sum to place
Employee in the same after-tax position Employee would have occupied absent the taxes attributable to such amounts. Such amounts shall be paid in accordance with Employer’s regular expense reimbursement policy that is now or hereinafter in
effect and in no event later than the last day of the year following the year in which the applicable expenses are incurred. 
 4.06 To assist
in Employee’s move to the Atlanta, Georgia area, Employer agrees to reimburse Employee for all reasonable and documented “moving expenses” incurred in moving Employee from Employee’s current residence to Employee’s new
residence in the Atlanta, Georgia area. For purposes of this Section 4.06, “moving expenses” means (a) the cost of moving Employee’s household goods (excluding extraordinary items, such as boats, spas, etc.),
(b) realtor fees on the sale of Employee’s primary residence that are not borne by the purchaser of such residence (up to a maximum of 6%), (c) costs associated with Employee’s temporary housing (up to a maximum of three months)
and (d) closing costs on the purchase of Employee’s new home, including legal fees (assuming a 0 point mortgage). Such amounts shall be paid in accordance with Employer’s regular expense reimbursement policy that is now or hereinafter
in effect and in no event later than the last day of the year following the year in which the applicable expenses are incurred. 
 4.07 Employee
shall be afforded the right to participate in any and all group medical, dental or life insurance and other benefit programs including Employer’s 401(k) plan, which may be in effect during his employment. Except as specifically provided in this

to the terms and conditions of such benefit plans and programs. 
 4.08 During Employee’s employment with Employer, Employee shall receive
four (4) weeks of paid vacation per year. Unused vacation time cannot be carried over into subsequent years. If Employee’s employment terminates pursuant to Section 15.08, then 

 

 3 









 
Employer shall pay Employee an amount equal to all of Employee’s accrued but unused vacation time through the date of termination on the next regularly scheduled payroll date of Employer
following termination. 
 4.09 To the fullest extent permitted by applicable law and Employer’s articles of incorporation and by-laws,
Employee shall be entitled to indemnification from the Employer for any loss, damage or claim incurred by Employee by reason of any act or omission performed or omitted by Employee in good faith on behalf of the Employer, and in a manner reasonably
believed to be within the scope of the authority conferred on Employee by this Agreement, except that Employee shall not be entitled to be indemnified in respect of any loss, damage or claim incurred by Employee by reason of gross negligence or
willful misconduct with respect to any such acts or omissions. During Employee’s employment with Employer, and while potential liability exists thereafter, the Employer shall maintain a directors’ and officers’ liability insurance
policy covering Employee in the same amount and to the same extent as the Employer covers its other officers and directors. 
 ARTICLE 5:
CONFIDENTIAL INFORMATION 
 5.01 During the course of his employment, Employer may disclose to Employee or the Employee may learn of and
about certain Trade Secrets and Confidential Information. 
 (a) “Trade Secrets” shall mean, individually or
collectively, any information regarding Employer, the Aquilex Entities, or their businesses that is proprietary, unique, not generally known by persons outside Employer, the Aquilex Entities, or their businesses, including, without limitation,
technical and non-technical information, data, formulae, programs, processes, sales and marketing data, customer information, both actual and prospective, financial data, product plans, manufacturing specifications and plans, equipment
specifications and modifications, suppliers, pricing methods and terms, and which (1) derives economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by other persons who can
obtain economic value from its disclosure or use; and (2) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy. 

(b) “Confidential Information” shall mean information, other than Trade Secrets, that is of value to Employer and is treated as
confidential by Employer, the Aquilex Entities, or their businesses, including but not limited to, business plans, strategies, information regarding executives and employees, and information of a type described above in the definition of Trade
Secrets but which may not fall expressly within such definition and yet is treated as confidential by Employer, the Aquilex Entities, or their businesses. 

Employee agrees that such Trade Secrets and Confidential Information are the sole and exclusive property of Employer and that Employer owns all of the
rights thereto. Employee shall have the right to use such Trade Secrets and Confidential Information in connection with his duties as an employee of Employer, but solely for the benefit of Employer. 

 

 4 









 5.02 Employee shall hold in strict confidence, and shall not use, reproduce, distribute, transmit, disclose
or otherwise transfer, in any form, directly or indirectly, or by any means, any of such Trade Secrets or Confidential Information. Upon termination of employment, whether by resignation or otherwise, Employee shall immediately return to Employer
all documents, writings, sketches, drawings, plans, specifications or any other embodiment (whether in software format, computer diskettes or otherwise) containing any information regarding Employer, including any Trade Secrets or Confidential
Information, together with all copies thereof. 
 5.03 Employee obligations regarding protection of Trade Secrets and Confidential Information
shall remain in effect: (a) with regard to Trade Secrets, for so long as such information shall remain Trade Secrets under applicable law; and (b) with regard to Confidential Information, until such Confidential Information is in the
public domain (but only if the same becomes part of the public domain through a means other than a disclosure prohibited hereunder). 
 5.04 Any
Trade Secrets or Confidential Information developed by Employee during his employment with Employer is hereby assigned to Employer, and if such information is deemed “contract for services work” under applicable law, it shall be owned
exclusively by Employer. 
 5.05 During the Employee’s employment with Employer and thereafter, the Employee shall not take any action to
disparage or criticize Employer or its affiliates, or their respective employees, officers, directors, owners or customers or to engage in any other action that injures or hinders the business relationships of Employer or its affiliates. During the
Employee’s employment with Employer and thereafter, the Employer shall not take any action to unfairly disparage or criticize Employee to any third party; provided, however, that this Section 5.05 shall not in any way
preclude the Employer from managing or supervising the Employee’s performance (or from engaging in meaningful discourse relating thereto). Nothing contained in this Section 5.05 shall preclude either party from enforcing his or its rights
under this Agreement. 
 ARTICLE 6: AGREEMENT NOT TO COMPETE 

6.01 In consideration of the compensation to be paid to Employee under this Agreement, Employee acknowledges that in the course of Employee’s
employment with Employer and the Aquilex Entities he has prior to the date of the Agreement, and will during his employment, become familiar with Employer’s and the Aquilex Entities’ trade secrets, business plans and business strategies
and with other confidential business information concerning Employer and the Aquilex Entities and that Employee’s services have been and shall be of special, unique and extraordinary value to Employer and the Aquilex Entities. In light of
Employee’s value to and knowledge of Employer, its customers and its business practices, Employee agrees that, during Employee’s employment hereunder and for a period of twelve (12) months thereafter (the “Noncompete
Period”), he will not seek, accept, or hold employment in a position substantially similar to that held by Employee with Employer during the term of his employment hereunder with any corporation or other enterprise, entity or association

  

 5 









 
which is directly competitive with any business that Employer or any Aquilex Entity engages in. Employee further agrees that, during the Noncompete Period, he shall not acquire or develop any
line of business, property or project that is directly competitive with any business engaged in or planned to be engaged in by Employer or any Aquilex Entity at the time of Employee’s termination, so long as Employee had direct involvement with
such business engaged in or planned to be engaged in by Employer or any Aquilex Entity. These restrictions shall cover Employee’s activities within a 50 mile radius of Employer’s location at 3399 Peachtree Road, Atlanta, Georgia 30326.

 ARTICLE 7: AGREEMENT NOT TO SOLICIT EMPLOYEES 

7.01 Employee shall not, during his employment with Employer, or for a period of two (2) years thereafter (“the Nonsolicit Period”) solicit
or attempt to solicit any person who is, or during the one (1) year prior to Employee’s termination was, an employee of Employer or any of the Aquilex Entities, for the purpose of employing such persons for any other employer or entity
engaged in the Employer’s or the Aquilex Entities’ business (“Employer’s Business”). 
 ARTICLE 8: AGREEMENT NOT TO
SOLICIT CUSTOMERS AND CLIENTS 
 8.01 During the Nonsolicit Period, Employee agrees not to, directly or indirectly, solicit or attempt to
solicit any former or current customer or client of Employer or any of the Aquilex Entities with whom Employee had material contact during the two (2) years immediately prior to termination of employment from Employer. For purposes of the
preceding sentence, “material contact” shall mean interaction which takes place in an effort to continue and/or expand the relationship and/or service between Employer and/or any of the Aquilex Entities and its current and former customers
and clients. The prohibition contained in this Section shall apply only to actual or attempted solicitation for the purpose of marketing or selling products or services which compete with those products or services offered by Employer and/or
any of the Aquilex Entities at the termination of Employee’s employment. The parties acknowledge that the nonsolicitation articles outlined in this Agreement are agreed to based upon consideration independent from the consideration for the
noncompete article, and that the parties intend these nonsolicitation provisions to be separate and independent agreements from the noncompete provision. The parties agree that the nonsolicitation provisions shall remain in force and effect, even if
a court of law determines that other provisions of this Agreement are unenforceable, including, but not limited to, the noncompete provision. 

ARTICLE 9: IRREPARABLE HARM 
 9.01 In the
event of any breach or threatened breach of Articles 5, 6, 7, or 8 of this Agreement, Employee acknowledges and agrees that Employer would be irreparably harmed thereby and that remedies at law would be inadequate. Accordingly, Employee agrees
that in such event, Employer shall be entitled to injunctive or other equitable relief to restrain or enjoin any such breach. 
  

 6 









 ARTICLE 10: REASONABLE RESTRICTIONS 

10.01 Employee agrees that the time, territorial and other limitations in Articles 5, 6, 7 and 8 are reasonable and properly required for the
adequate protection of Employer’s Business. If anything is found unreasonable by a court of law or equity Employee agrees to be bound to any revision as the court may determine to be reasonable. If any limitation is found to be unreasonable in
any jurisdiction, Employee agrees to be bound by the limitation in any other jurisdiction. 
 ARTICLE 11: SEVERABILITY OF RESTRICTIVE
COVENANTS 
 11.01 If any provision or any part of any provisions of this Agreement is held invalid or unenforceable by any court, such
holding shall not affect the validity or enforceability of any other provisions hereof, all of which shall remain in full force and effect. Specifically, Employee agrees that if any portion, or all, of Articles 5, 6, 7, or 8, is found
unreasonable by a court of law or equity, and the court finds that particular section invalid as a matter of law, he shall remain bound by the remaining such sections. Employee agrees that any ruling that Article 5, 6, 7 or 8 is
unenforceable shall not render any other such Article unenforceable. 
 ARTICLE 12: TOLLING OF RESTRICTIONS 

12.01 In the event that either party initiates litigation in an attempt to confirm or enforce its rights under this Agreement, the parties agree that the
period during which Employee is prohibited from competing with Employer or the Aquilex Entities or soliciting customers and personnel from Employer or the Aquilex Entities as described in Articles 6, 7 or 8 will be tolled during the period of
time in which such litigation is pending. 
 ARTICLE 13: ARBITRATION 

13.01 The parties agree to have any and all disputes concerning this Agreement or concerning Employee’s employment with Employer resolved via
arbitration. Accordingly, the parties agree that any such dispute shall, as the sole and exclusive remedy, be submitted for resolution through binding arbitration to be held in Atlanta, Georgia, in accordance with the employment arbitration rules
(except as modified below) of the American Arbitration Association. Employment-related disputes include any and all disputes related, in any manner whatsoever, to Employee’s hiring, employment, or termination including, but not limited to,
claims or charges based upon federal or state statutes, including, but not limited to, Age Discrimination in Employment, Title VII of the Civil Rights Act of 1964, as amended, and any other civil rights statute, the Americans with Disabilities Act,
Family and Medical Leave Act, Fair Labor Standards Act or other wage statutes, the WARN Act, claims based upon tort or contract laws or any other federal or state law affecting employment in any manner whatsoever. 

13.02 In the event that a claim is brought pursuant to any law or statute that provides for the allocation of attorneys’ fees and/or costs, the
arbitrator shall have the power to allocate attorneys’ fees and costs pursuant to the applicable law or statutes. 
  

 7 









 13.03 Employer and Employee agree that arbitration pursuant to this Agreement shall be in accordance with
the rules of the American Arbitration Association. To the extent that any rule or provision of the American Arbitration Association differ from the terms provided herein, the terms of this agreement shall override the aforesaid rule and govern the
arbitration. The parties specifically agree that they shall share equally the costs, fees, and expenses incurred by arbitration, except in the following circumstances: 

In the event the Employee is unable to pay his share of the costs of arbitration due to financial hardship, the Employee may apply to the
AAA for “in forma pauperis” status in accordance with the criteria established by the applicable United States Circuit Court of Appeals. Alternatively, the Employee may apply to the AAA for the use of a pro bono arbitrator or
for waiver, reduction or deferral of the AAA’s fees based upon financial hardship. The AAA shall determine whether the employee qualifies for financial hardship or waiver, reduction or deferral of the AAA’s fees and costs. 

13.04 Employer and Employee agree that, in addition to the rules of the American Arbitration Association, the arbitration proceedings will be conducted
in accordance with the appropriate federal or state rules of evidence, civil procedure and appellate procedure. In cases premised on federal jurisdiction, the Federal Rules of Evidence, Federal Rules of Civil Procedure and Federal Rules of Appellate
Procedure shall apply. In cases premised on state jurisdiction, the applicable state rules of evidence, civil procedure and appellate procedure shall apply. In cases of concurrent jurisdiction, the federal rules shall apply. The arbitrator shall
write an opinion stating all findings of fact and conclusions of law with respect to the arbitration decision. Employer and Employee agree that the arbitrator’s rulings shall be appealable on the same grounds as a judgment rendered by a court
of law (“trial court”). The parties acknowledge that the arbitrator’s decision will be reviewed under the same standard of review used in reviewing a trial court’s decision and will be governed by the applicable rules of
appellate procedure referenced hereinabove. 
 13.05 The sole exception to this agreement to arbitrate involves suits brought on behalf of
Employer or Employee seeking a temporary restraining order, preliminary injunction and/or permanent injunction (“injunctive relief”) based upon violation of non-compete, and/or confidentiality, and/or non-disclosure, and/or
non-disparagement, and/or solicitation agreements, in the event there is immediate and irreparable injury, loss or damage. The parties agree that neither shall seek monetary damages under this exception to the agreement to arbitrate. However, in the
event that Employer is successful in obtaining injunctive relief as defined herein, Employee shall be liable for payment of Employer’s attorneys’ fees, costs, and expenses incurred in connection with obtaining injunctive relief.

 13.06 This agreement to arbitrate shall be binding upon and inure to the benefit of any successor to Employer and such successor shall be
deemed substituted for Employer under the terms of this agreement. As used in this agreement to arbitrate, the term “successor” shall include any person, firm, limited liability company or other business entity, which at any time, whether
by merger, purchase or otherwise, acquires all or substantially all the assets of the business of Employer. This agreement to arbitrate also shall be binding upon and inure to the benefit of Employee, his heirs, executors and administrators.

  

 8 









 13.07 If any part, term or provision of this agreement to arbitrate is held to be illegal, void or
unenforceable, or to be in conflict with any law, the validity of the remaining provisions or portions of this agreement shall not be affected, and the rights of the parties shall be construed and enforced as if this agreement did not contain the
particular part, term or provision held invalid.

ARTICLE 14: EMPLOYER’S PROPERTY 

14.01 Upon termination of this agreement, for any reason or cause, Employee shall promptly return to Employer all property used by him in the performance
of his duties and all other property belonging to Employer in Employee’s possession or control. 
 ARTICLE 15: TERMINATION

 15.01 The employment of Employee under the terms and conditions of this Agreement shall automatically terminate upon the expiration of the
Term. Subject to Employer’s obligations set forth below, the employment of Employee hereunder and the Term may also be terminated at any time by the Employer with or without cause. 

15.02 If Employer terminates Employee’s employment without cause or if Employee terminates employment with Employee Cause or in the event of the
expiration of the Term pursuant to Employer providing Employee with notice of non-renewal under Section 3.01, Employer will provide Employee with severance pay consisting of (a) continued periodic payments of Employee’s base salary
(as set forth in Section 4.01) for the longer of (i) twelve (12) months, or (ii) the remainder of the Term as of the date of termination; and (b) any pro rata share (based upon the applicable period of Employee’s
employment through the date of termination) of any applicable incentive bonus, payable, in either case, in accordance with Employer’s regular payroll practices. In addition, to the extent permitted by applicable law and Employer’s
insurance and benefits policies, Employer shall maintain Employee’s paid coverage for health insurance (through the payment of Employee’s COBRA premiums; provided that Employee shall be required to pay the portion of the cost of such
coverage as is paid by Employer’s actively employed employees from time to time) and other dental and life insurance benefits for the period Employee is receiving severance pay. With respect to any such continued health insurance and other
dental and life insurance benefits, (A) such benefits shall be discontinued in the event Employee becomes eligible for similar benefits from any other employer; and (B) Employee’s period of “continuation coverage” for
purposes of Section 4980B of the Internal Revenue Code of l986, as amended, shall be deemed to commence on the date of the Employee’s termination of employment. Employee shall notify Employer in writing of his eligibility for any such
benefits from another employer within five (5) days after such eligibility. 
  

 9 









 15.03 If Employer terminates Employee’s employment for cause, if Employee terminates employment without
Employee Cause (as defined below) or in the event of Employee’s death or the expiration of the Term pursuant to Employee providing Employer with notice of non-renewal under Section 3.01, Employee shall not be entitled to severance
benefits. “For cause” as used in this Article shall mean termination by Employer for any of the following: (a) Employee’s gross negligence in the performance of the duties and services required of Employee pursuant to this
Agreement; (b) Employee’s conviction of or plea of guilty or nolo contendere to a felony or Employee engaging in fraudulent or criminal activity relating to the scope of Employee’s employment (whether or not prosecuted); (c) a
material violation of Employer’s Code of Business Conduct, provided that Employee has received written notice from the Employer and been afforded a reasonable opportunity (not less than ten (10) days nor more than twenty-five
(25) days) to cure such violation; (d) Employee’s breach of any material provision of this Agreement, provided that Employee has received written notice from the Employer and been afforded a reasonable opportunity (not less than
thirty (30) days nor more than forty-five (45) days) to cure such breach; (e) failure to perform the duties as requested by the Employee’s supervisor(s) or the Board of Directors of Employer after Employee has been afforded a
reasonable opportunity (not less than thirty (30) days nor more than forty-five (45) days) to cure such failure; (f) the commission of a felony or crime involving moral turpitude; or (g) conduct that brings Employer into public
disgrace or disrepute in any respect. Determination as to whether or not Employer Cause exists for termination of Executive’s employment will be made by the Board of Directors of Employer. 

15.04 Termination by Employee for Employee Cause. “Employee Cause” shall mean a termination of employment by Employee because of (a) the
assignment to Employee of any significant duties materially inconsistent with Employee’s status as Chief Operating Officer of Employer or a substantial diminution in the nature of Employee’s responsibilities or Employee’s status,
(b) a material breach by Employer of any material provision of this Agreement, (c) a demand by Employer that Employee relocate from the Atlanta, Georgia metropolitan area or (d) a salary reduction in any amount. In order for Employee
to terminate for Employee Cause, (A) Employer must be notified by Employee in writing within ninety (90) days of the event constituting Employee Cause, (B) the event must remain uncorrected by Employer for thirty (30) days
following such notice (the “Notice Period”) and (C) such termination must occur within sixty (60) days after the expiration of the Notice Period. Notwithstanding anything in this Agreement to the contrary, an across-the-board
salary reduction similarly affecting Employee and all other executives of Employer shall not give rise to an Employee Cause. 
 15.05 As a
condition to the receipt of such severance benefit or such additional consideration as Employer may provide, Employer, will require Employee to first execute a release, in the form reasonably established by Employer, releasing Employer, the Aquilex
Entities, and their officers, directors, employees, successors, assigns, attorneys and agents, from any and all claims and from any and all causes of action of any kind or character, including, but not limited to, all claims and causes of action
arising out of Employee’s employment with Employer and any other Aquilex Entities or the termination of such employment, including, but not limited to, all claims or demands for 

 

 10 









 
back pay, reinstatement, hire or rehire, front pay and any claim of discrimination under federal or state law, including, but not limited to, any claims under the Age Discrimination in Employment
Act of 1967, as amended; the Americans with Disabilities Act of 1990; the Fair Labor Standards Act; the Family and Medical Leave Act; 42 U.S.C. § 1981; and Title VII of the Civil Rights Act of 1964, as amended by the Civil Rights Act of 1991,
or any other constitutional principle, or federal or state statute based upon discrimination. The release required by this Section 15.05 shall be completed and be irrevocable prior to the 60th day following Employee’s termination of
employment in order for Employee to be eligible to receive the benefits described in Section 15.02. Notwithstanding anything to the contrary contained in Section 15.02, if Employee executes the release required by this Section 15.05
within 60 days following Employee’s termination of employment, payments under Section 15.02 shall commence no later than 60 days after Employee’s termination of Employment and shall in no event be required to commence prior to that
time; provided that, if payments are delayed under this sentence, then any such delayed payments shall be made (without interest) at the time of the first regularly scheduled payroll period coincident with or next following the expiration of such
60-day period. 
 15.06 Notwithstanding the foregoing, if, at the time of Employee’s termination of employment with Employer, Employee is a
“specified employee” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and one or more of the payments or benefits received or to be received by Employee pursuant to this
Agreement would constitute deferred compensation within the meaning of Section 409A of the Code, then no such payment will be made under this Agreement before the date that is six months after his separation from service (within the meaning of
Section 409A of the Code) or, if earlier, his date of death. At the conclusion of such six-month period, any payments delayed pursuant to this Section 15.06 shall be made (without interest) at the time of the first regularly scheduled
payroll period coincident with or next following the expiration of such six month period, to the extent Employee is otherwise entitled to commence receipt of such payments under this Agreement. 

15.07 Employee acknowledges that receipt and acceptance of any severance benefit shall constitute full settlement of all claims and causes of action
against Employer. 
 15.08 Employee may terminate Employee’s employment with Employer without Employee Cause thirty (30) days’
after notice to Employer.

which may hereafter acquire or succeed to all or substantially all of the business assets of Employer by any means, whether indirectly or directly, and whether by purchase, merger, consolidation, or otherwise. No such assignment shall relieve
