 AGREEMENT: 
 NOW, THEREFORE, in consideration of such employment and the mutual
covenants and promises herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Executive agree as follows: 
  

	 	1.	 	Employment and Position. Subject to Section 2, the Company hereby employs the Executive as its Chief Executive Officer, and the Executive hereby accepts such
employment under and subject to the terms and conditions hereinafter set forth. 

  

	 	2.	 	Term. The term of employment under this Agreement began on the date of the Original Agreement and, unless sooner terminated as provided in Section 6, shall
conclude on the fifth anniversary of the Original Agreement (the “Employment Term”). 

	 	3.	 	Duties. The Executive shall perform services in a managerial capacity in a manner consistent with the Executive’s position as Chief Executive Officer of the Company,
subject to the general supervision of the Board of Managers (the “Board”) of the Company. The Executive hereby agrees to devote his full business time and diligent efforts to the faithful performance of such duties and to the
promotion and forwarding of the business and affairs of the Company for the Employment Term; provided, however, that the Executive may (i) serve on non-profit civic or charitable boards or committees, (ii) manage the
Executive’s passive investments in Persons in which the Executive has no managerial responsibilities, so long as the activities specified in provisos (i) and (ii) above do not significantly interfere with the performance and
fulfillment of the Executive’s duties and responsibilities as an employee of the Company in accordance with this Agreement. Any other actions or opportunities may be pursued by the Executive only with the express written consent of the Board.

  

	 	4.	 	Compensation. 

  

	 	 (a)
	 	 Salary. In consideration of the services rendered by the Executive under this Agreement, the Company shall pay
the Executive a base salary (the “Base Salary”) at the rate of $500,000 per calendar year. The Base Salary shall be paid in such installments and at such times as the Company pays its regularly salaried executives and shall be
subject to all necessary withholding taxes, FICA contributions and similar deductions, as well as set-off against any amounts Executive owes the Company or its affiliates. 

  

	 	(b)	 	Target Bonus. During the Employment Term, the Company from time to time, but in any event no later than the time the Company pays its bonuses in accordance with its general
payroll policies following the end of each fiscal year, shall pay the Executive an annual bonus (the “Target Bonus”) of up to two hundred percent (200%) of the Base Salary. The Target Bonus shall be calculated and payable in
accordance with and based on the Actual EBITDA of the Company by reference to the Budgeted EBITDA. The Target Bonus shall be calculated and payable as described in Schedule 1 hereto. 

 For purposes of this Agreement, “EBITDA” shall mean the earnings of the Company and its consolidated subsidiaries before interest,
taxes, depreciation, accretion and amortization, calculated in accordance with generally accepted accounting principles. For purposes of this Agreement, “Actual EBITDA” shall mean, for any fiscal year of the Company, the EBITDA of
the Company and its consolidated subsidiaries for such fiscal year as reflected on the Company’s financial statements for such fiscal year; provided, however, that (i) all amounts paid to Goldberg Lindsay & Co. LLC
(“Goldberg Lindsay”), Peterson Capital Inc. (“Peterson Capital”) and Creamer Investments, Inc. (“Creamer Investments”) pursuant to the terms of the Advisory Services Agreements by and between each
of Goldberg Lindsay, Peterson Capital, and Creamer Investments and the 

  

 2 

 
Company, (ii) all amounts contributed to the “EnergySolutions, LLC Charitable Trust,” or such similar entity, if such an entity is created,
and (iii) all amounts paid to any employee of the Company as an “Excess Performance Bonus” under the terms of his or her employment agreement with the Company (including, for the avoidance of doubt, all Excess Performance Bonus paid
to the Executive under the terms of this Agreement) shall be excluded from Actual EBITDA. For purposes of this Agreement, “Budgeted EBITDA” shall mean, for any fiscal year of the Company, the EBITDA for the Company and its
consolidated subsidiaries for such fiscal year set forth in the budget for such fiscal year adopted by the Board. 
  

	 	(c)	 	Excess Performance Bonus Pool. During the Employment Term, the Company from time to time, but in any event no later than the time the Company pays its bonuses in
accordance with its general payroll policies following the end of each fiscal year, shall pay the Executive an excess performance bonus (the “Excess Performance Bonus”) of four percent (4%) of Excess EBITDA; provided,
however, that any Excess EBITDA that results from Actual EBITDA exceeding one hundred and twenty percent (120%) of Plan EBITDA shall be excluded in calculating the Excess Performance Bonus payable to the Executive pursuant to this
Section 4(c) for any given fiscal year. 

 For purposes of this Agreement, “Excess EBITDA” shall
mean, for any fiscal year of the Company, the excess of Actual EBITDA over Plan EBITDA. 
 For purposes of this Agreement, “Plan
EBITDA” shall mean, for any fiscal year of the Company and its consolidated subsidiaries, the forecasted EBITDA number set forth on Schedule 2 attached hereto; provided, however, that Plan EBITDA may be changed at the
sole discretion of the Board to account for (i) any acquisition or disposition by, or merger or other business combination of, the Company or (ii) capital expenditures for any fiscal year exceeding $15 million in the aggregate. 

Notwithstanding the above, if on or prior to December 31, 2007 there is any underwritten public offering of securities of the Company, the
Company’s parent or EnergySolutions Group, Inc. pursuant to an effective registration statement under the Securities Act of 1933 (“IPO”), the Company and Executive agree and acknowledge that the excess performance bonus that is
provided for in this Agreement shall be eliminated (including the elimination of all references to the excess bonus plan in this Agreement) and the Executive hereby waives any payments with respect thereto that may have become payable from time to
time, if not for the elimination of such excess performance bonus, and as consideration therefore, the Executive shall be entitled to receive a one-time lump sum payment of $2,344,000, less any applicable withholding 

  

 3 

 
taxes, on the closing of the IPO. In the event of an IPO, the Executive will, at the Company’s request, enter into an amendment of this Agreement to
reflect the appropriate entity as the “Company”. 
  

	 	 (d)
	 	 Retention Payment upon Change of Control. In addition to the compensation above, on the one year anniversary of
any Change of Control, so long as the Executive remains employed by the Company, the Executive shall be paid in a lump sum an amount equal to (i) Base Salary for one year, plus (ii) the Target Bonus paid for the immediately preceding year.
For purposes hereof, a “Change of Control” shall mean (i) a sale of all or substantially all of the assets of the Company, (ii) the sale by ENV Holdings, LLC (“ENV Holdings”) and its Affiliates
(collectively, the “Member”), to a Person other than an Affiliate of the Member, in a single transaction or a series of related transactions, of more than 65% of the equity interests of the Company, (iii) a merger,
consolidation or similar transaction involving the Company, immediately following which, the Member fails to own at least 50.1% of the voting power of the successor entity or (iv) a merger, consolidation, sale of equity interests, or similar
transaction, in a single transaction or series of related transactions, pursuant to which the current holders of all of the Class A Units of ENV Holdings cease to own at least 20% of the voting equity of ENV Holdings (or any successor to ENV
Holdings) following such transaction or series of related transactions. 

  

	 	(e)	 	Management Units. In consideration of the prior services rendered by the Executive to the Company, ENV Holdings has previously granted to the Executive a certain amount of
(i) Class B Units of ENV Holdings (the “Class B Units”) and (ii) Class C Units, Class D Units and Class E Units of ENV Holdings (collectively, the “Management Units”), which Class B Units and
Management Units are subject to the terms and conditions of the Third Amended and Restated Limited Liability Company Agreement of ENV Holdings, dated as of June 7, 2006, as the same is in effect from time to time (the “Amended
Agreement”). 

  

	 	(f)	 	Individual Business Objectives. Notwithstanding anything to the contrary contained herein, payment of the Target Bonus and the Excess Performance Bonus to the Executive shall
be contingent on successful completion of the Executive’s Individual Business Objectives (“IBOs”). The IBOs for the Executive shall be discussed and agreed to by the Executive and the Board during the first quarter of the
Company’s fiscal year. Payment of the Target Bonus and Excess Performance Bonus to the Executive may be forfeited or reduced, at the discretion of the Board, if the Executive’s safety, compliance or core competencies (as outlined in the
Executive’s IBOs) are deemed to be unsatisfactory. 

  

	 	5.	 	Benefits. In addition to the compensation detailed in Section 4 of this Agreement, the Executive shall be entitled to the following additional benefits:

  

	 	(a)	 	Paid Vacation. The Executive shall be entitled to four (4) weeks paid vacation per calendar year, such vacation to extend for such periods and to be taken at such
intervals as shall be appropriate and consistent with the proper performance of the Executive’s duties hereunder. 

  

 4 

	 	(b)	 	Insurance Coverage. During the Employment Term, the Executive and/or the Executive’s family, as the case may be, shall be eligible for participation in welfare benefit

death and travel accident insurance plans and programs) to the extent applicable generally to other executives of the Company. The Company may, at its election and for its benefit, insure the Executive against disability, accidental loss or death
and the Executive shall submit to such physical examinations and supply such information as may be required in connection therewith. 

  

	 	(c)	 	Reimbursement of Expenses. The Company shall reimburse the Executive for all reasonable and necessary expenses actually incurred by the Executive directly in connection with
the business affairs of the Company and the performance of his duties hereunder, upon presentation of proper receipts or other proof of expenditure and subject to such reasonable guidelines or limitations provided by the Company from time to time.
The Executive shall comply with such reasonable limitations and reporting requirements with respect to such expenses as the Board may establish from time to time. 

  

	 	(d)	 	Other Benefit Plans. During the Employment Term, the Executive shall be entitled to participate in all savings, retirement and pension plans, practices, policies and programs
applicable generally to other executives of the Company as determined by the Board from time to time; provided, however, that the Executive shall not be entitled to any vacation, bonus or severance other than as specifically outlined

	 	(ii)	the Executive shall have failed or refused to carry out the reasonable and lawful instructions of the Board (other than as a result of illness or disability) concerning duties or

	 	7.	 	Termination Payments and Benefits. 

  

	 	(a)	 	Termination by the Company Without Cause or by the Executive for Good Reason. If the Company shall terminate the Executive’s employment without Cause, or the Executive

(i) the number of days which the Executive was employed by the Company during such fiscal year, divided by 365, multiplied by (ii) the Executive’s Target Bonus and Excess Performance Bonus which, but for the Executive’s
termination of employment, would have been earned by the Executive during such year. For purposes of this Agreement, “Welfare Benefit Continuation” shall mean the provision of welfare benefits such that the Executive shall continue

Executive’s heirs, executors, administrators or other legal representatives under this Agreement, other than for (i) payment of all Accrued Obligations, plus (ii) at the time the Company pays its employees bonuses in accordance with
its general payroll policies, the Pro Rata Bonus. Notwithstanding the foregoing, the obligation of the Company to make the payment provided for in Section 7(b)(ii) shall be contingent on the Executive’s heirs, executors,
administrators or other legal representatives under this Agreement executing a release of the Company and its principals, employees, agents, officers, directors, shareholders, managers, members, partners, professionals, affiliates and direct and
indirect subsidiaries from any and all claims related to the Executive’s employment to the maximum extent permitted by law. 

  

	 	(c)	 	Permanent Disability. If the Executive’s employment is terminated by reason of the Executive’s Permanent Disability, this Agreement shall terminate without further
obligations to the Executive, other than for (i) payment of all Accrued Obligations, plus (ii) as long as the Executive does not violate the provisions of Section 8 and Section 9 hereof, at the time the Company pays
its employees bonuses in accordance with its general payroll policies, the Pro Rata Bonus. Notwithstanding the foregoing, the obligation of the Company to make the payment provided for in Section 7(c)(ii) shall be contingent on the

	 	(d)	 	Termination by the Company for Cause. If the Executive’s employment is terminated for Cause, this Agreement shall terminate without further obligations to the Executive
other than for payment of all Accrued Obligations. 

  

	 	(e)	 	Termination by the Executive. If the Executive voluntarily terminates the Executive’s employment, excluding a termination for Good Reason, this Agreement shall terminate
without further obligations to the Executive, other than for payment of all Accrued Obligations. 

  

	 	(f)	 	Accrued Obligations. Notwithstanding anything else herein to the contrary, all Accrued Obligations to which the Executive (or his estate or beneficiary) is entitled shall be
payable in cash (in a lump sum) no later than forty-five (45) days following termination this Agreement, except as otherwise specifically provided herein or under the terms of any applicable policy, plan or program. 

  

	 	(g)	 	Complete Payment. The payments and other benefits to be made or to be extended to the Executive under the provisions of this Section 7 upon termination of the
Executive’s employment shall be in complete satisfaction of any and all payments that would otherwise be due the Executive had he remained employed by the Company during the remainder of the Employment Term and the Company shall have no further
obligation to make any payment or extend any benefit to the Executive pursuant to this Agreement or otherwise upon or after such termination. Except as specifically provided in this Section 7, the Executive shall not be entitled to any
compensation, severance or other benefits from the Company or any of its subsidiaries or Affiliates upon the termination of this Agreement for any reason whatsoever. The Executive shall not be entitled to any severance or other payments upon
termination of employment except pursuant to this Agreement. 

  

	 	(h)	 	Survival of Certain Provisions. Provisions of this Agreement shall survive any termination of employment if so provided herein or if necessary or desirable fully to
accomplish the purposes of such provision, including, without limitation, the obligations of the Executive under Section 8 and Section 9 hereof. The obligation of the Company to make payments to or on behalf of the Executive

Agreement. 

  

	 	(b)	 	Fiduciary Obligations. The Executive agrees that Confidential Information is of critical importance to the Company and a violation of this Section 8(b) and

benefit or for the benefit of any other Person. At the termination of his employment, the Executive shall deliver to the Company all notes, letters, documents and records which may contain Confidential Information which are then in his possession or

	 	10.	 	 Section 409A Compliance. To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A of the Internal Revenue Code
of 1986, as amended, and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the date hereof (“409A
Guidance”). 

  

 13 

	 	 
Notwithstanding any provision of the Agreement to the contrary, (i) if, at the time of the Executive’s termination of employment with the Company,
the Executive is a “specified employee” as defined in 409A Guidance and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent
any accelerated or additional tax under 409A Guidance, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided to the
Executive) until the date that is six months following the Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A) and (ii) if any other payments of money or other benefits due
to the Executive hereunder could cause the application of an accelerated or additional tax under Section 409A, the Company may (a) adopt such amendments to the Agreement, including amendments with retroactive effect, that the Company
determines necessary or appropriate to preserve the intended tax treatment of the benefits provided by the Agreement and/or (b) take such other actions as the Company determines necessary or appropriate to comply with the requirements of 409A
Guidance. The Company shall consult with the Executive in good faith regarding the implementation of this Section 10; provided that none of the Company, any of its affiliates, or any of its employees or representatives shall have any
liability to the Executive with respect thereto. 

  

	 	11.	 	Remedies. It is specifically understood and agreed that any breach of the provisions of Section 8 or Section 9 of this Agreement is likely to result
in irreparable injury to the Company and that the remedy at law alone will be an inadequate remedy for such breach, and that in addition to any other remedy it may have, the Company shall be entitled to enforce the specific performance of this
Agreement by the Executive and to obtain both temporary and permanent injunctive relief without bond and without liability should such relief be denied, modified or violated. Neither the right to obtain such relief nor the obtaining of such relief
shall be exclusive or preclude the Company from any other remedy. 

  

	 	12.	 	Severability. The parties hereto agree that, if any court of competent jurisdiction in a final nonappealable judgment determines that a specified time period, a specified
geographical area, a specified business limitation or any other relevant feature of Section 8 or Section 9 is unreasonable, arbitrary or against public policy, then a lesser time period, geographical area, business limitation
or other relevant feature which is determined to be reasonable, not arbitrary and not against public policy may be enforced against the applicable party. Any other provision of this Agreement that is deemed invalid or unenforceable shall be
ineffective to the extent of such invalidity or unenforceability, without rendering invalid or unenforceable the remaining provisions of this Agreement. 

  

	 	13.	 	Notices. All notices and other communications contemplated by this Agreement shall be in writing. Any notice or other communication contemplated by this Agreement shall be
deemed to have been duly given (i) on the date of delivery, if delivered by hand or (ii) two business days after it is sent by registered or certified mail, return receipt requested, postage prepaid, and addressed to the intended recipient
as set forth below:

	 	14.	 	 Arbitration of Disputes. (a) Any dispute, controversy, or claim (collectively, any “Dispute”) arising between the Company and the
Executive relating to or arising from this Agreement other than the Company’s right to seek injunctive relief for breach of Section 8 or Section 9 of this Agreement, shall be submitted to and settled by binding
arbitration in the Las Vegas, Nevada office of the American Arbitration Association (“AAA”) conducted pursuant to the rules then in effect of the AAA governing employment disputes, before three (3) neutral arbitrators licensed
to practice law for at least ten years and familiar with employment law disputes (or at any other place or under any other form of arbitration mutually acceptable to the parties so involved). Any award rendered in any Dispute shall be final and
conclusive upon the parties to the arbitration, and the judgment thereon may be entered in the highest court of the forum (state or federal) having jurisdiction over the issues addressed in the arbitration. The administration fees and expenses of
the arbitration shall be borne equally by the parties to the arbitration, provided that each party shall pay for and bear the cost of its/his/her own experts, evidence and attorney’s fees. In the discretion of the arbitrators, any award may
include the cost of a party’s counsel and/or its share of the expense of arbitration, if the arbitrators expressly determine that an award of such costs is appropriate to the party whose position prevails in such arbitration. To submit a matter
to arbitration, the party seeking redress (“Claimant”) shall notify in writing the party against whom such redress is sought (“Respondent”), describe the nature of such claim, the provision of this Agreement that
has been violated by the 

  

 15 

	 	 
Respondent and the material facts surrounding such claim. At any arbitration hearing, each of the parties shall have the right to make both written and oral
presentations to the arbitrators. Within thirty (30) days of the conclusion of such arbitration hearing, the arbitrators shall render a single written decision. The decision of the arbitrators shall be binding upon the Claimant and Respondent,
and after the completion of such arbitration, the Claimant and Respondent may only institute litigation regarding the Dispute for the sole purpose of enforcing the determination of the arbitration hearing. By agreeing to arbitration under this
Section 14, the Company and the Executive understand that they are each waiving any right to a trial by jury and each party makes that waiver knowingly and voluntarily with full consideration of the ramifications of such waiver.

  

	 	15.	 	Miscellaneous. 

  

	 	(a)	 	Amendment. This Agreement may not be amended or revised except by a writing signed by the parties. 

  

	 	(b)	 	Assignment and Transfer. The provisions of this Agreement shall be binding on and shall inure to the benefit of the Company and its successors and assigns. Neither this
Agreement nor any of the rights, duties or obligations of the Executive shall be assignable by the Executive, nor shall any of the payments required or permitted to be made to the Executive by this Agreement be encumbered, transferred or in any way
anticipated, except as required by applicable laws. However, all rights of the Executive under this Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, estates, executors,
administrators, heirs and beneficiaries. All amounts payable to the Executive hereunder shall be paid, in the event of the Executive’s death, to the Executive’s estate, heirs or representatives. 

  

	 	(c)	 	Waiver of Breach. A waiver by the Company or the Executive of any breach of any provision of this Agreement by the other party shall not operate or be construed as a waiver
of any other or subsequent breach by the other party. 

  

	 	(d)	 	Withholding. The Company shall be entitled to withhold from any amounts to be paid or benefits provided to the Executive hereunder any federal, state, local, or foreign
withholding or other taxes or charges which it is from time to time required to withhold. The Company shall be entitled to rely on an opinion of counsel if any question as to the amount or requirement of any such withholding shall arise.

  

	 	(e)	 	Captions. Captions herein have been inserted solely for convenience of reference and in no way define, limit or describe the scope or substance of any provision of this
Agreement. 

  

 16 

	 	(f)	 	Attorney’s Fees. In the event that any action is brought to enforce any of the provisions of this Agreement, or to obtain money damages for the breach thereof, and such
action results in the award of a judgment for money damages or in the granting of any injunction in favor of one of the parties to this Agreement, all expenses, including reasonable attorneys’ fees, shall be paid by the non-prevailing party.

  

	 	(g)	 	Entire Agreement. All of (i) this Agreement and (ii) the Amended Agreement constitute the entire understanding of the parties hereto with respect to the subject
matter hereof and supercede all prior negotiations, discussions, writings and agreements between the parties with respect to such subject matter. 

  

	 	(h)	 	Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original and shall have the same effect as if the signatures hereto
and thereto were on the same instrument. 

  

	 	(i)	 	Governing Law. This Agreement shall be governed and interpreted in accordance with the laws of the state of Utah, without regard to the conflicts of law provisions thereof.

  

	 	(j)	 	Definitions. As used herein, (i) the term “Affiliate” means, with respect to any Person, any other Person that, directly or indirectly, through one or
more intermediaries, controls, is controlled by or is under common control with, such Person, and each of the terms “control,” “controlled by” and “under common control with” means the possession, directly or
indirectly, of the power to direct or cause the direction of the management and policies of such Person, whether through ownership of voting securities, by contract or otherwise and (ii) the term “Person” means any individual,
corporation, partnership, firm, joint venture, association, joint-stock company, trust, unincorporated organization, government or governmental or regulatory body thereof, or political subdivision thereof, or any agency, instrumentality or authority

 Target Bonus

	 Percentage of Base Salary payable as Target Bonus
	  	0	%	 	100	%	 	200	%

 The Target Bonus payable to the Executive hereunder for each fiscal year is to be interpolated for Actual EBITDA
between 80% and 100% or between 100% and 110% of Budgeted EBITDA. 
 For example, if Actual EBITDA represents 85% of Budgeted EBITDA, a Target Bonus of 25%
of the Executive’s Base Salary would be payable, calculated as follows: 
  

	 	(1)	 	The increase of Actual EBITDA over the 80% of Budgeted EBITDA benchmark, which in this case equals 5%, is divided by the difference between (a) 100% and (b) 80% (the two
applicable Budgeted EBITDA benchmarks), yielding 25%; 

  

	 	(2)	 	This amount (25%) is then multiplied by the difference between (x) 100% (the Target Bonus at 100% of Budgeted EBITDA) and (y) 0% (the Target Bonus at 80% of Budgeted
EBITDA), which equals 25% of the Executive’s Base Salary as the Target Bonus. 

 On the other hand, if Actual EBITDA represents 105% of
Budgeted EBITDA, then a Target Bonus of 150% of the Executive’s Base Salary would be payable, calculated as follows: 
  

	 	(1)	 	The increase of Actual EBITDA over the 100% of Budgeted EBITDA benchmark, which in this case equals 5%, is divided by the difference between (a) 110% and (b) 100% (the two
applicable Budgeted EBITDA benchmarks), yielding 50%; 

  

	 	(2)	 	This amount (50%) is then multiplied by the difference between (x) 200% (the Target Bonus at 110% of Budgeted EBITDA) and (y) 100% (the Target Bonus at 100% of
Budgeted EBITDA), which equals 50% of the Executive’s Base Salary as the Target Bonus payable for the increase of 5% over the 100% Budgeted EBITDA Benchmark; 

  

	 	(3)	 	This amount (50% of Base Salary) is then added to the 100% of Base Salary that was earned when Actual EBITDA met the 100% of Budgeted EBITDA Benchmark, which equals an aggregate
total of 150% of the Executive’s Base Salary as the Target Bonus.

 AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AND NON-COMPETITION AGREEMENT 
 This AMENDED AND
RESTATED EXECUTIVE EMPLOYMENT AND NON-COMPETITION AGREEMENT (this “Agreement”), dated as of January 9, 2007, is entered into by and between ENERGYSOLUTIONS, LLC, a Utah limited liability company (the
“Company”), and JEAN I. “CHIP” EVEREST II (the “Executive”). 
 WITNESSETH: 
 WHEREAS, the Company and its subsidiaries are engaged in a variety of activities in connection with the treatment, storage, disposal and transportation
of low-level radioactive waste and low-level mixed waste and related field services (the “Business”), as permitted by certain licenses granted to the Company and its subsidiaries by certain federal and state regulatory authorities;

 WHEREAS, the Company and the Executive entered into that certain Executive Employment and Non-Competition Agreement, dated as of
January 31, 2005 (the “Original Agreement”); 
 WHEREAS, the Company and the Executive desire to amend and restate the
Original Agreement; 
 WHEREAS, the Company desires to be assured that the unique and expert services of the Executive will be substantially
available to the Company, and that the Executive is willing and able to render such services on the terms and conditions hereinafter set forth; and 
 WHEREAS, the Company desires to be assured that the confidential information and goodwill of the Company will be preserved for the exclusive benefit of the Company. 
 AGREEMENT: 
 NOW, THEREFORE, in consideration of such employment and the mutual
covenants and promises herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Executive agree as follows: 
  

	 	1.	 	Employment and Position. Subject to Section 2, the Company hereby employs the Executive as its Chief Financial Officer, and the Executive hereby accepts such
employment under and subject to the terms and conditions hereinafter set forth. 

  

	 	2.	 	Term. The term of employment under this Agreement began on the date of the Original Agreement and, unless sooner terminated as provided in Section 6, shall
conclude on the fifth anniversary of the Original Agreement (the “Employment Term”). 

	 	3.	 	Duties. The Executive shall perform services in a managerial capacity in a manner consistent with the Executive’s position as Chief Financial Officer of the Company,
subject to the general supervision of the President and Chief Executive Officer and the Board of Managers (the “Board”) of the Company. The Executive hereby agrees to devote his full business time and diligent efforts to the
faithful performance of such duties and to the promotion and forwarding of the business and affairs of the Company for the Employment Term; provided, however, that the Executive may (i) serve on non-profit civic or charitable
boards or committees, (ii) manage the Executive’s passive investments in Persons in which the Executive has no managerial responsibilities, so long as the activities specified in provisos (i) and (ii) above do not significantly
interfere with the performance and fulfillment of the Executive’s duties and responsibilities as an employee of the Company in accordance with this Agreement. Any other actions or opportunities may be pursued by the Executive only with the
express written consent of the Board. 

  

	 	4.	 	Compensation. 

  

	 	(a)	 	Salary. In consideration of the services rendered by the Executive under this Agreement, the Company shall pay the Executive a base salary (the “Base
Salary”) at the rate of $300,000 per calendar year. The Base Salary shall be paid in such installments and at such times as the Company pays its regularly salaried executives and shall be subject to all necessary withholding taxes, FICA
contributions and similar deductions, as well as set-off against any amounts Executive owes the Company or its affiliates. 

  

	 	(b)	 	Target Bonus. During the Employment Term, the Company from time to time, but in any event no later than the time the Company pays its bonuses in accordance with its general
payroll policies following the end of each fiscal year, shall pay the Executive an annual bonus (the “Target Bonus”) of up to two hundred percent (200%) of the Base Salary. The Target Bonus shall be calculated and payable in
accordance with and based on the Actual EBITDA of the Company by reference to the Budgeted EBITDA. The Target Bonus shall be calculated and payable as described in Schedule 1 hereto. 

 For purposes of this Agreement, “EBITDA” shall mean the earnings of the Company and its consolidated subsidiaries before interest,
taxes, depreciation, accretion and amortization, calculated in accordance with generally accepted accounting principles. For purposes of this Agreement, “Actual EBITDA” shall mean, for any fiscal year of the Company, the EBITDA of
the Company and its consolidated subsidiaries for such fiscal year as reflected on the Company’s financial statements for such fiscal year; provided, however, that (i) all amounts paid to Goldberg Lindsay & Co. LLC
(“Goldberg Lindsay”), Peterson Capital Inc. (“Peterson Capital”) and Creamer Investments, Inc. (“Creamer Investments”) pursuant to the terms of the Advisory Services Agreements by and between each
of 

  

 2 

 
Goldberg Lindsay, Peterson Capital, and Creamer Investments and the Company, (ii) all amounts contributed to the “EnergySolutions, LLC Charitable
Trust,” or such similar entity, if such an entity is created, and (iii) all amounts paid to any employee of the Company as an “Excess Performance Bonus” under the terms of his or her employment agreement with the Company
(including, for the avoidance of doubt, all Excess Performance Bonus paid to the Executive under the terms of this Agreement) shall be excluded from Actual EBITDA. For purposes of this Agreement, “Budgeted EBITDA” shall mean, for
any fiscal year of the Company, the EBITDA for the Company and its consolidated subsidiaries for such fiscal year set forth in the budget for such fiscal year adopted by the Board. 
  

	 	(c)	 	Excess Performance Bonus Pool. During the Employment Term, the Company from time to time, but in any event no later than the time the Company pays its bonuses in
accordance with its general payroll policies following the end of each fiscal year, shall pay the Executive an excess performance bonus (the “Excess Performance Bonus”) of three and a half percent (3.5%) of Excess EBITDA;
provided, however, that any Excess EBITDA that results from Actual EBITDA exceeding one hundred and twenty percent (120%) of Plan EBITDA shall be excluded in calculating the Excess Performance Bonus payable to the Executive
pursuant to this Section 4(c) for any given fiscal year. 

 For purposes of this Agreement, “Excess
EBITDA” shall mean, for any fiscal year of the Company, the excess of Actual EBITDA over Plan EBITDA. 
 For purposes of this
Agreement, “Plan EBITDA” shall mean, for any fiscal year of the Company and its consolidated subsidiaries, the forecasted EBITDA number set forth on Schedule 2 attached hereto; provided, however, that Plan
EBITDA may be changed at the sole discretion of the Board to account for (i) any acquisition or disposition by, or merger or other business combination of, the Company or (ii) capital expenditures for any fiscal year exceeding $15 million
in the aggregate. 
 Notwithstanding the above, if on or prior to December 31, 2007 there is any underwritten public offering of
securities of the Company, the Company’s parent or EnergySolutions Group, Inc. pursuant to an effective registration statement under the Securities Act of 1933 (“IPO”), the Company and Executive agree and acknowledge that the
excess performance bonus that is provided for in this Agreement shall be eliminated (including the elimination of all references to the excess bonus plan in this Agreement) and the Executive hereby waives any payments with respect thereto that may
have become payable from time to time, if not for the elimination of such excess performance bonus, and as consideration therefore, the Executive shall be entitled to receive a one- 

  

 3 

 
time lump sum payment of $2,051,000, less any applicable withholding taxes, on the closing of the IPO. In the event of an IPO, the Executive will, at the
Company’s request, enter into an amendment of this Agreement to reflect the appropriate entity as the “Company”. 
  

	 	 (d)
	 	 Retention Payment upon Change of Control. In addition to the compensation above, on the one year anniversary of
any Change of Control, so long as the Executive remains employed by the Company, the Executive shall be paid in a lump sum an amount equal to (i) Base Salary for one year, plus (ii) the Target Bonus paid for the immediately preceding year.
For purposes hereof, a “Change of Control” shall mean (i) a sale of all or substantially all of the assets of the Company, (ii) the sale by ENV Holdings, LLC (“ENV Holdings”) and its Affiliates
(collectively, the “Member”), to a Person other than an Affiliate of the Member, in a single transaction or a series of related transactions, of more than 65% of the equity interests of the Company, (iii) a merger,
consolidation or similar transaction involving the Company, immediately following which, the Member fails to own at least 50.1% of the voting power of the successor entity or (iv) a merger, consolidation, sale of equity interests, or similar
transaction, in a single transaction or series of related transactions, pursuant to which the current holders of all of the Class A Units of ENV Holdings cease to own at least 20% of the voting equity of ENV Holdings (or any successor to ENV
Holdings) following such transaction or series of related transactions. 

  

	 	(e)	 	Management Units. In consideration of the prior services rendered by the Executive to the Company, ENV Holdings has previously granted to the Executive a certain amount of
(i) Class B Units of ENV Holdings (the “Class B Units”) and (ii) Class C Units, Class D Units and Class E Units of ENV Holdings (collectively, the “Management Units”), which Class B Units and
Management Units are subject to the terms and conditions of the Third Amended and Restated Limited Liability Company Agreement of ENV Holdings, dated as of June 7, 2006, as the same is in effect from time to time (the “Amended
Agreement”). 

  

	 	(f)	 	Individual Business Objectives. Notwithstanding anything to the contrary contained herein, payment of the Target Bonus and the Excess Performance Bonus to the Executive shall
be contingent on successful completion of the Executive’s Individual Business Objectives (“IBOs”). The IBOs for the Executive shall be discussed and agreed to by the Executive and the President and CEO of the Company during the
first quarter of the Company’s fiscal year. Payment of the Target Bonus and Excess Performance Bonus to the Executive may be forfeited or reduced, at the discretion of the President and CEO of the Company, if the Executive’s safety,
compliance or core competencies (as outlined in the Executive’s IBOs) are deemed to be unsatisfactory. 

  

 4 

	 	5.	 	Benefits. In addition to the compensation detailed in Section 4 of this Agreement, the Executive shall be entitled to the following additional benefits:

  

	 	(a)	 	Paid Vacation. The Executive shall be entitled to four (4) weeks paid vacation per calendar year, such vacation to extend for such periods and to be taken at such
intervals as shall be appropriate and consistent with the proper performance of the Executive’s duties hereunder. 

  

	 	(b)	 	Insurance Coverage. During the Employment Term, the Executive and/or the Executive’s family, as the case may be, shall be eligible for participation in welfare benefit
plans, practices, policies and programs provided by the Company to similarly-situated executives of the Company (including, without limitation, medical, prescription, dental, disability, salary continuance, employee life, group life, accidental
death and travel accident insurance plans and programs) to the extent applicable generally to other executives of the Company. The Company may, at its election and for its benefit, insure the Executive against disability, accidental loss or death
and the Executive shall submit to such physical examinations and supply such information as may be required in connection therewith. 

  

	 	(c)	 	Reimbursement of Expenses. The Company shall reimburse the Executive for all reasonable and necessary expenses actually incurred by the Executive directly in connection with
the business affairs of the Company and the performance of his duties hereunder, upon presentation of proper receipts or other proof of expenditure and subject to such reasonable guidelines or limitations provided by the Company from time to time.
The Executive shall comply with such reasonable limitations and reporting requirements with respect to such expenses as the Board may establish from time to time. 

  

	 	(d)	 	Other Benefit Plans. During the Employment Term, the Executive shall be entitled to participate in all savings, retirement and pension plans, practices, policies and programs
applicable generally to other executives of the Company as determined by the Board from time to time; provided, however, that the Executive shall not be entitled to any vacation, bonus or severance other than as specifically outlined
herein. 

  

	 	6.	 	Termination. This Agreement shall be terminated at the end of the Employment Term or earlier as follows: 

  

	 	(a)	 	Death. This Agreement shall automatically terminate upon the death of the Executive during the Employment Term. 

  

	 	(b)	 	Permanent Disability. In the event of any physical or mental disability of the Executive rendering the Executive unable to perform his duties hereunder for a period of at
least one hundred twenty (120) days out of any twelve (12) month period (“Permanent Disability”), the employment of the Executive and this Agreement shall terminate automatically. 

  

 5 

	 	 (c)
	 	 By the Company For Cause. The employment of the Executive may be terminated by the Company for Cause (as defined
below) at any time effective upon written notice to the Executive. For purposes of this Agreement, the term “Cause” shall mean that the Board has determined that any one or more of the following has occurred:

  

	 	(i)	the Executive shall have been convicted of, or shall have pleaded guilty or nolo contendere to, any felony; 

  

	 	(ii)	the Executive shall have failed or refused to carry out the reasonable and lawful instructions of the Board or the President and Chief Executive Officer of the Company (other than
as a result of illness or disability) concerning duties or actions consistent with the Executive’s position as Chief Financial Officer of the Company and such failure or refusal shall have continued for a period of ten (10) days following
written notice from the Board; 

  

	 	(iii)	the Executive shall have breached any material provision of this Agreement and such breach shall not have been cured, or if curable, within ten (10) days following written
notice from the Board of such breach; 

  

	 	(iv)	the Executive shall fail to adhere to any material written Company policy and such failure to comply shall not have been cured, or if curable, within ten (10) days following
written notice from the Board of such failure; 

  

	 	(v)	the Executive shall have engaged in any gross or willful misconduct resulting in a substantial loss to the Company or substantial damage to its reputation; or

  

	 	(vi)	the Executive shall have committed any fraud, embezzlement, misappropriation of funds, breach of fiduciary duty or other act of dishonesty against the Company.

  

	 	(d)	 	By the Company without Cause. The Company may terminate the Executive’s employment at any time without Cause effective upon sixty (60) days prior written notice to
the Executive. 

  

	 	(e)	 	By the Executive Voluntarily. The Executive may terminate this Agreement at any time effective upon at least sixty (60) days prior written notice to the Company.

  

	 	(f)	 	 By the Executive for Good Reason. The Executive may terminate this Agreement effective upon written notice to the Company for Good Reason 

  

 6 

	 	 
(subject to the cure period set forth below). Such notice must provide a detailed explanation of the Good Reason. For this purpose, the term “Good
Reason” shall mean: (i) the assignment to the Executive of any duties inconsistent in any substantial respect with the Executive’s position, authority or responsibilities as contemplated by Section 3 of this Agreement
or any duties which are illegal or any material diminution of any of the Executive’s significant duties; (ii) any material reduction in any of the benefits described in Section 4 or Section 5 of this Agreement; or
(iii) any other material breach of this Agreement by the Company. Notwithstanding the foregoing, in the event the Executive provides notice of his intention to terminate for Good Reason as outlined in the immediately preceding sentence, the
Company shall have the opportunity to cure such Good Reason within thirty (30) days of receiving such notice. Notwithstanding anything to the contrary contained herein, a Change of Control, alone, does not constitute Good Reason.

  

	 	7.	 	Termination Payments and Benefits. 

  

	 	(a)	 	Termination by the Company Without Cause or by the Executive for Good Reason. If the Company shall terminate the Executive’s employment without Cause, or the Executive
shall terminate the Executive’s employment for Good Reason, the Executive shall be entitled to receive, as his exclusive right and remedy in respect of such termination: (i) the payment of (A) all Accrued Obligations, plus (B) as
long as the Executive does not violate the provisions of Section 8 and Section 9 hereof, at the time the Company pays its employees bonuses in accordance with its general payroll policies, the Pro Rata Bonus, plus (C) as
long as the Executive does not violate the provisions of Section 8 and Section 9 hereof, severance pay equal to Executive’s then current monthly Base Salary, payable in accordance with the Company’s regular pay
schedule, for twelve (12) months from the date of termination of employment and (ii) the provision of the Welfare Benefit Continuation. Notwithstanding the foregoing, the obligation of the Company to make the payments provided for in
Section 7(a)(i)(B) and Section 7(a)(i)(C) shall be contingent on the Executive executing a release of the Company and its principals, employees, agents, officers, directors, shareholders, managers, members, partners,
professionals, affiliates and direct and indirect subsidiaries from any and all claims related to the Executive’s employment to the maximum extent permitted by law. 

 For purposes of this Agreement, “Accrued Obligations” shall mean, (1) all Base Salary earned or accrued (and not yet paid) through
the date the Executive’s employment is terminated, (2) reimbursement for any and all monies advanced in connection with the Executive’s employment for reasonable and necessary expenses incurred by the Executive through the date the
Executive’s employment is terminated and (3) all other payments and benefits to which the Executive may be entitled under the terms of any

applicable compensation arrangement or benefit plan or program of the Company, except that Accrued Obligations shall not include (i) any entitlement to
any severance under any Company severance policy generally applicable to the Company’s salaried employees or (ii) any entitlement to all or any portion of the Target Bonus or the Excess Performance Bonus. For purposes of this Agreement,
“Pro Rata Bonus” shall mean, as to any fiscal year of the Company in which the Executive’s employment with the Company is terminated, an amount equal to the product of (i) the number of days which the Executive was
employed by the Company during such fiscal year, divided by 365, multiplied by (ii) the Executive’s Target Bonus and Excess Performance Bonus which, but for the Executive’s termination of employment, would have been earned by the
Executive during such year. For purposes of this Agreement, “Welfare Benefit Continuation” shall mean the provision of welfare benefits such that the Executive shall continue to be covered, upon the same terms and conditions as
described hereinabove, by the same or equivalent medical, dental, and life insurance coverages as in effect for the Executive immediately prior to the termination of his employment, until the earlier of (A) the expiration of the period for
which he receives severance pay pursuant this Agreement or (B) the date the Executive has commenced new employment and has thereby become eligible for comparable benefits, subject to the Executive’s rights under the Consolidated Omnibus
Budget Reconciliation Act (COBRA). 
  

	 	(b)	 	Death. If the Executive’s employment is terminated by reason of the Executive’s death, this Agreement shall terminate without further obligations to the
Executive’s heirs, executors, administrators or other legal representatives under this Agreement, other than for (i) payment of all Accrued Obligations, plus (ii) at the time the Company pays its employees bonuses in accordance with
its general payroll policies, the Pro Rata Bonus. Notwithstanding the foregoing, the obligation of the Company to make the payment provided for in Section 7(b)(ii) shall be contingent on the Executive’s heirs, executors,
administrators or other legal representatives under this Agreement executing a release of the Company and its principals, employees, agents, officers, directors, shareholders, managers, members, partners, professionals, affiliates and direct and
indirect subsidiaries from any and all claims related to the Executive’s employment to the maximum extent permitted by law. 

  

	 	(c)	 	 Permanent Disability. If the Executive’s employment is terminated by reason of the Executive’s Permanent Disability, this Agreement shall terminate
without further obligations to the Executive, other than for (i) payment of all Accrued Obligations, plus (ii) as long as the Executive does not violate the provisions of Section 8 and Section 9 hereof, at the time
the Company pays its employees bonuses in accordance with its general payroll policies, the Pro Rata Bonus. Notwithstanding the foregoing, the obligation of the Company to make the payment provided for in 

  

 8 

	 	 
Section 7(c)(ii) shall be contingent on the Executive executing a release of the Company and its principals, employees, agents, officers,
directors, shareholders, managers, members, partners, professionals, affiliates and direct and indirect subsidiaries from any and all claims related to the Executive’s employment to the maximum extent permitted by law.

  

	 	(d)	 	Termination by the Company for Cause. If the Executive’s employment is terminated for Cause, this Agreement shall terminate without further obligations to the Executive
other than for payment of all Accrued Obligations. 

  

	 	(e)	 	Termination by the Executive. If the Executive voluntarily terminates the Executive’s employment, excluding a termination for Good Reason, this Agreement shall terminate
without further obligations to the Executive, other than for payment of all Accrued Obligations. 

  

	 	(f)	 	Accrued Obligations. Notwithstanding anything else herein to the contrary, all Accrued Obligations to which the Executive (or his estate or beneficiary) is entitled shall be
payable in cash (in a lump sum) no later than forty-five (45) days following termination this Agreement, except as otherwise specifically provided herein or under the terms of any applicable policy, plan or program. 

  

	 	(g)	 	Complete Payment. The payments and other benefits to be made or to be extended to the Executive under the provisions of this Section 7 upon termination of the
Executive’s employment shall be in complete satisfaction of any and all payments that would otherwise be due the Executive had he remained employed by the Company during the remainder of the Employment Term and the Company shall have no further
obligation to make any payment or extend any benefit to the Executive pursuant to this Agreement or otherwise upon or after such termination. Except as specifically provided in this Section 7, the Executive shall not be entitled to any
compensation, severance or other benefits from the Company or any of its subsidiaries or Affiliates upon the termination of this Agreement for any reason whatsoever. The Executive shall not be entitled to any severance or other payments upon
termination of employment except pursuant to this Agreement. 

  

	 	(h)	 	Survival of Certain Provisions. Provisions of this Agreement shall survive any termination of employment if so provided herein or if necessary or desirable fully to
accomplish the purposes of such provision, including, without limitation, the obligations of the Executive under Section 8 and Section 9 hereof. The obligation of the Company to make payments to or on behalf of the Executive
under this Section 7 is expressly conditioned upon the Executive’s continued full performance of obligations under Section 8 and Section 9 hereof. The Executive recognizes that, except as expressly provided
in this Section 7, no compensation is earned after termination of employment. 

  

 9 

	 	8.	 	Confidential Information; Inventions in the Field. 

  

	 	(a)	 	Confidential Information. In the course of service to the Company, the Executive will have or will have had access to confidential specifications, know-how, strategic or
technical data, marketing research data, financial information, pricing information, product research and development data, manufacturing techniques, confidential customer lists, sources of supply and trade secrets, and other confidential
information with respect to the Company, all of which are confidential and may be proprietary and are owned or used by the Company, or any of its subsidiaries or Affiliates. Such information shall hereinafter be called “Confidential
Information” and shall include any and all items enumerated in the preceding sentence and coming within the scope of the business of the Company or any of its subsidiaries or Affiliates as to which the Executive may have access, whether
conceived or developed by others or by the Executive alone or with others during the period of service to the Company, whether or not conceived or developed during regular working hours. Confidential Information shall not include any records, data
or information which are in the public domain during or after the period of service by the Executive provided the same are not in the public domain as a consequence of disclosure directly or indirectly by the Executive in violation of this
Agreement. 

  

	 	(b)	 	Fiduciary Obligations. The Executive agrees that Confidential Information is of critical importance to the Company and a violation of this Section 8(b) and
Section 8(c) would seriously and irreparably impair and damage the Company’s business. The Executive agrees that he shall keep all Confidential Information in a fiduciary capacity for the sole benefit of the Company.

  

	 	(c)	 	Non-Use and Non-Disclosure. The Executive shall not during the Employment Term or at any time thereafter (a) disclose, directly or indirectly, any Confidential
Information to any Person other than the Company or executives thereof at the time of such disclosure who, in the reasonable judgment of the Executive, need to know such Confidential Information or such other Persons to whom the Executive has been
specifically instructed to make disclosure by the Board and in all such cases only to the extent required in the course of the Executive’s service to the Company or (b) use any Confidential Information, directly or indirectly, for his own
benefit or for the benefit of any other Person. At the termination of his employment, the Executive shall deliver to the Company all notes, letters, documents and records which may contain Confidential Information which are then in his possession or
control and shall destroy any and all copies and summaries thereof. 

  

 10 

	 	(d)	 	Assignment of Inventions. The Executive agrees to assign and transfer to the Company or its designee, without any separate remuneration or compensation, his entire right,
title and interest in and to all Inventions in the Field (as defined below), together with all United States and foreign rights with respect thereto, and at the Company’s expense to execute and deliver all appropriate patent and copyright
applications for securing United States and foreign patents and copyrights on Inventions in the Field and to perform all lawful acts, including giving testimony, and to execute and deliver all such instruments that may be necessary or proper to vest
all such Inventions in the Field and patents and copyrights with respect thereto in the Company, and to assist the Company in the prosecution or defense of any interference which may be declared involving any of said patent applications, patents,
copyright applications or copyrights. For the purposes of this Agreement, the words “Inventions in the Field” shall include any discovery, process, design, development, improvement, application, technique, or invention, whether
patentable or copyrightable or not and whether reduced to practice or not, conceived or made by the Executive, individually or jointly with others (whether on or off the Company’s premises or during or after normal working hours) while in the
employ of the Company, and which was or is directly or indirectly related to the business of the Company or any of its subsidiaries, or which resulted or results from any work performed by any Executive or agent thereof during the Employment Term.

  

	 	(e)	 	Return of Documents. All notes, letters, documents, records, tapes and other media of every kind and description relating to the business, present or otherwise, of the
Company or its Affiliates and any copies, in whole or in part, thereof (collectively, the “Documents”), whether or not prepared by the Executive, shall be the sole and exclusive property of the Company. The Executive shall safeguard
all Documents and shall surrender to the Company at the time his employment terminates, or at such earlier time or times as the Board or its designee may specify, all Documents then in the Executive’s possession or control.

  

	 	9.	 	Restrictions on Activities of the Executive. 

  

	 	(a)	 	 Acknowledgments. The Executive and Company agree that the Executive is being employed hereunder in a key capacity with the Company and that the Company is
engaged in a competitive business and that the success of the Company’s business in the marketplace depends upon its goodwill and reputation for quality and dependability. The Executive and Company further agree that (i) reasonable limits
may be placed on his ability to compete against the Company as provided herein to the extent that they protect and preserve the legitimate business interests and goodwill of the Company and (ii) such limits are (A) in consideration for and
as an inducement for, among other things, the Executive’ purchase of the Class A Units of ENV Holdings pursuant to the Original Agreement, the 

  

 11 

	 	 
Executive’s receipt of prior grants of the Class B Units and the Management Units, and the continued employment of the Executive by the Company,
(B) the result of arms-length negotiations between the parties, (C) reasonable in scope and duration, and (D) necessary to protect the legitimate business interests of the Company and its Affiliates. The Executive acknowledges that he
has carefully read this Agreement and given careful consideration to the restraints imposed upon the Executive by this Agreement, and is in full accord as to their necessity for the reasonable and proper protection of the Confidential Information,
whether now existing or to be developed in the future. The Executive acknowledges that he has consulted with his own independent tax and legal advisor regarding this Agreement and the provisions contained herein. 

  

	 	(b)	 	Non-Competition. During the Employment Term and for the Non-Competition Period (as defined below), the Executive will not, individually or jointly, and he will cause his
Affiliates not to, directly or indirectly, for himself or themselves, or for the benefit of any other Person, without the prior written consent of the Company, its successor or assigns, which consent may or may not be given in the Company’s (or
such successor’s or assign’s) sole discretion, own, manage, engage in, operate, control, develop, or participate in the ownership, management, operation, control or development of, consult with or perform services for, or be connected in
any manner with, any Person (other than the Company, at the Company’s sole discretion) that engages in any aspect of the Business or processes low-level radioactive waste or low-level mixed waste anywhere in the United States of America or that
otherwise competes with the Company (a “Competitive Business”); provided, however, the acquisition, directly or indirectly, of less than 5% of the publicly traded stock of any Person engaged in a Competitive Business
shall not constitute a violation of this Section 9(b). 

 For purposes of this Agreement, the
“Non-Competition Period” shall mean a period of two (2) years after the Executive’s employment terminates. 
  

	 	(c)	 	Non-Solicitation. During the Employment Term and the Non-Solicitation Period (as defined below), the Executive will not (A) solicit or hire, or attempt to solicit or
hire, any person who (i) at the time of the termination of the Executive’s employment with the Company hereunder or (ii) at any time during the six (6) month period prior to such termination, was an officer, director, consultant
or executive of the Company or any of its subsidiaries or Affiliates or (B) call upon, solicit, divert or attempt to solicit or divert from the Company or any of its Affiliates or subsidiaries any of their customers or suppliers, or potential
customers or suppliers, of whose names he was aware during the term of his employment with the Company; provided, however, that nothing in this Section 9(c) shall be deemed to prohibit the Executive from calling upon or
soliciting a customer or supplier during the Non-Solicitation Period if such action relates solely to a business which is not a Competitive Business. 

  

 12 

 For purposes of this Agreement, the “Non-Solicitation Period” shall mean a period of
two (2) years after the Executive’s employment terminates. 
  

	 	(d)	 	Public Statements. During the Employment Term, the Executive shall take such actions as are reasonably necessary to cause the Company to be in compliance with
Section 4(ee) of the Purchase Agreement, dated as of December 10, 2004, by and among ENV Holdings, Khosrow B. Semnani, the Khosrow B. Semnani Revocable Trust, Lindsay Goldberg & Bessemer L.P. (solely for the purposes of
Section 11(m) thereof), and the Company (solely for the purposes of Section 4(ee) thereof), as amended by that certain First Amendment to Purchase Agreement, dated January 13, 2005. 

  

	 	(e)	 	Non-disparagement. At no time during the Employment Term or for a period of two (2) years thereafter, shall the Executive disparage or denigrate the Company or its
officers, directors, managers, employees or agents as it relates to the operations of the Company; provided, however, that nothing herein is intended to or will act in any manner to prevent the Executive from presenting testimony,
making statements or providing information in connection with and relevant to any legal or governmental investigation or proceeding or making any disclosures required by law, subpoena or court order. 

  

	 	(f)	 	Related Businesses. During the Employment Term, the Executive agrees that, to the extent he has been notified of an opportunity to acquire or make an investment in any
business (including, without limitation, a Competitive Business) related or complementary to the Business of the Company (a “Potential Investment”), he shall inform the Board of such Potential Investment promptly upon receiving
notice thereof and provide the Company with the first opportunity to participate in such Potential Investment. 

  

	 	(g)	 	THE EXECUTIVE REPRESENTS AND WARRANTS THAT THE KNOWLEDGE, SKILLS AND ABILITIES HE POSSESSES AT THE TIME OF COMMENCEMENT OF EMPLOYMENT HEREUNDER ARE SUFFICIENT TO PERMIT HIM, IN THE
EVENT OF TERMINATION OF HIS EMPLOYMENT HEREUNDER, TO EARN A LIVELIHOOD SATISFACTORY TO HIMSELF WITHOUT VIOLATING ANY PROVISION OF SECTION 8 OR SECTION 9 HEREOF, FOR EXAMPLE, BY USING SUCH KNOWLEDGE, SKILLS AND ABILITIES, OR SOME OF
THEM, IN THE SERVICE OF A BUSINESS THAT IS NOT A COMPETITIVE BUSINESS. 

  

	 	10.	 	 Section 409A Compliance. To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A of the Internal Revenue Code
of 

  

 13 

	 	 
1986, as amended, and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations
or other guidance that may be issued after the date hereof (“409A Guidance”). Notwithstanding any provision of the Agreement to the contrary, (i) if, at the time of the Executive’s termination of employment with the
Company, the Executive is a “specified employee” as defined in 409A Guidance and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order
to prevent any accelerated or additional tax under 409A Guidance, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided
to the Executive) until the date that is six months following the Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A) and (ii) if any other payments of money or other
benefits due to the Executive hereunder could cause the application of an accelerated or additional tax under Section 409A, the Company may (a) adopt such amendments to the Agreement, including amendments with retroactive effect, that the
Company determines necessary or appropriate to preserve the intended tax treatment of the benefits provided by the Agreement and/or (b) take such other actions as the Company determines necessary or appropriate to comply with the requirements
of 409A Guidance. The Company shall consult with the Executive in good faith regarding the implementation of this Section 10; provided that none of the Company, any of its affiliates, or any of its employees or representatives shall have any
liability to the Executive with respect thereto. 

  

	 	11.	 	Remedies. It is specifically understood and agreed that any breach of the provisions of Section 8 or Section 9 of this Agreement is likely to result
in irreparable injury to the Company and that the remedy at law alone will be an inadequate remedy for such breach, and that in addition to any other remedy it may have, the Company shall be entitled to enforce the specific performance of this
Agreement by the Executive and to obtain both temporary and permanent injunctive relief without bond and without liability should such relief be denied, modified or violated. Neither the right to obtain such relief nor the obtaining of such relief
shall be exclusive or preclude the Company from any other remedy. 

  

	 	12.	 	Severability. The parties hereto agree that, if any court of competent jurisdiction in a final nonappealable judgment determines that a specified time period, a specified
geographical area, a specified business limitation or any other relevant feature of Section 8 or Section 9 is unreasonable, arbitrary or against public policy, then a lesser time period, geographical area, business limitation
or other relevant feature which is determined to be reasonable, not arbitrary and not against public policy may be enforced against the applicable party. Any other provision of this Agreement that is deemed invalid or unenforceable shall be
ineffective to the extent of such invalidity or unenforceability, without rendering invalid or unenforceable the remaining provisions of this Agreement. 

  

 14 

	 	13.	 	Notices. All notices and other communications contemplated by this Agreement shall be in writing. Any notice or other communication contemplated by this Agreement shall be
deemed to have been duly given (i) on the date of delivery, if delivered by hand or (ii) two business days after it is sent by registered or certified mail, return receipt requested, postage prepaid, and addressed to the intended recipient

	 	14.	 	 Arbitration of Disputes. (a) Any dispute, controversy, or claim (collectively, any “Dispute”) arising between the Company and the
Executive relating to or arising from this Agreement other than the Company’s right to seek injunctive relief for breach of Section 8 or Section 9 of this Agreement, shall be submitted to and settled by binding
arbitration in the Las Vegas, Nevada office of the American Arbitration Association (“AAA”) conducted pursuant to the rules then in effect of the AAA governing employment disputes, before three (3) neutral arbitrators licensed
to practice law for at least ten years and familiar with employment law disputes (or at any other place or under any other form of arbitration mutually acceptable to the parties so involved). Any award rendered in any Dispute shall be final and
conclusive upon the parties to the arbitration, and the judgment thereon may be entered in the highest court of the forum (state or federal) having jurisdiction over the issues addressed in the arbitration. The administration fees and expenses of
the arbitration shall be borne equally by the parties to the arbitration, provided that each party shall pay for and bear the cost of its/his/her own experts, evidence and attorney’s fees. In the discretion of the arbitrators, any award may
include the cost of a party’s counsel and/or its share of the expense of arbitration, if the arbitrators expressly determine that an award of such costs is 

  

 15 

	 	 
appropriate to the party whose position prevails in such arbitration. To submit a matter to arbitration, the party seeking redress
(“Claimant”) shall notify in writing the party against whom such redress is sought (“Respondent”), describe the nature of such claim, the provision of this Agreement that has been violated by the Respondent and the
material facts surrounding such claim. At any arbitration hearing, each of the parties shall have the right to make both written and oral presentations to the arbitrators. Within thirty (30) days of the conclusion of such arbitration hearing,
the arbitrators shall render a single written decision. The decision of the arbitrators shall be binding upon the Claimant and Respondent, and after the completion of such arbitration, the Claimant and Respondent may only institute litigation
regarding the Dispute for the sole purpose of enforcing the determination of the arbitration hearing. By agreeing to arbitration under this Section 14, the Company and the Executive understand that they are each waiving any right to a
trial by jury and each party makes that waiver knowingly and voluntarily with full consideration of the ramifications of such waiver. 

  

	 	15.	 	Miscellaneous. 

  

	 	(a)	 	Amendment. This Agreement may not be amended or revised except by a writing signed by the parties. 

  

	 	(b)	 	Assignment and Transfer. The provisions of this Agreement shall be binding on and shall inure to the benefit of the Company and its successors and assigns. Neither this
Agreement nor any of the rights, duties or obligations of the Executive shall be assignable by the Executive, nor shall any of the payments required or permitted to be made to the Executive by this Agreement be encumbered, transferred or in any way
anticipated, except as required by applicable laws. However, all rights of the Executive under this Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, estates, executors,
administrators, heirs and beneficiaries. All amounts payable to the Executive hereunder shall be paid, in the event of the Executive’s death, to the Executive’s estate, heirs or representatives. 

  

	 	(c)	 	Waiver of Breach. A waiver by the Company or the Executive of any breach of any provision of this Agreement by the other party shall not operate or be construed as a waiver
of any other or subsequent breach by the other party. 

  

	 	(d)	 	Withholding. The Company shall be entitled to withhold from any amounts to be paid or benefits provided to the Executive hereunder any federal, state, local, or foreign
withholding or other taxes or charges which it is from time to time required to withhold. The Company shall be entitled to rely on an opinion of counsel if any question as to the amount or requirement of any such withholding shall arise.

  

 16 

	 	(e)	 	Captions. Captions herein have been inserted solely for convenience of reference and in no way define, limit or describe the scope or substance of any provision of this
Agreement. 

  

	 	(f)	 	Attorney’s Fees. In the event that any action is brought to enforce any of the provisions of this Agreement, or to obtain money damages for the breach thereof, and such
action results in the award of a judgment for money damages or in the granting of any injunction in favor of one of the parties to this Agreement, all expenses, including reasonable attorneys’ fees, shall be paid by the non-prevailing party.

  

	 	(g)	 	Entire Agreement. All of (i) this Agreement and (ii) the Amended Agreement constitute the entire understanding of the parties hereto with respect to the subject
matter hereof and supercede all prior negotiations, discussions, writings and agreements between the parties with respect to such subject matter. 

  

	 	(h)	 	Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original and shall have the same effect as if the signatures hereto
and thereto were on the same instrument. 

  

	 	(i)	 	Governing Law. This Agreement shall be governed and interpreted in accordance with the laws of the state of Utah, without regard to the conflicts of law provisions thereof.

  

	 	(j)	 	Definitions. As used herein, (i) the term “Affiliate” means, with respect to any Person, any other Person that, directly or indirectly, through one or
more intermediaries, controls, is controlled by or is under common control with, such Person, and each of the terms “control,” “controlled by” and “under common control with” means the possession, directly or
indirectly, of the power to direct or cause the direction of the management and policies of such Person, whether through ownership of voting securities, by contract or otherwise and (ii) the term “Person” means any individual,

 SIGNATURE TO 
 AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AND NON-COMPETITION AGREEMENT 

 Schedule 1 
 Target Bonus 
  

										
	 	  	Percentage that Actual EBITDA for a fiscal year
represents of Budgeted EBITDA for such fiscal year	 
	  	80%	 	 	100%	 	 	110%	 
	 Percentage of Base Salary payable as Target Bonus
	  	0	%	 	100	%	 	200	%

 The Target Bonus payable to the Executive hereunder for each fiscal year is to be interpolated for Actual EBITDA
between 80% and 100% or between 100% and 110% of Budgeted EBITDA. 
 For example, if Actual EBITDA represents 85% of Budgeted EBITDA, a Target Bonus of 25%
of the Executive’s Base Salary would be payable, calculated as follows: 
  

	 	(1)	 	The increase of Actual EBITDA over the 80% of Budgeted EBITDA benchmark, which in this case equals 5%, is divided by the difference between (a) 100% and (b) 80% (the two
applicable Budgeted EBITDA benchmarks), yielding 25%; 

  

	 	(2)	 	This amount (25%) is then multiplied by the difference between (x) 100% (the Target Bonus at 100% of Budgeted EBITDA) and (y) 0% (the Target Bonus at 80% of Budgeted
EBITDA), which equals 25% of the Executive’s Base Salary as the Target Bonus. 

 On the other hand, if Actual EBITDA represents 105% of
Budgeted EBITDA, then a Target Bonus of 150% of the Executive’s Base Salary would be payable, calculated as follows: 
  

	 	(1)	 	The increase of Actual EBITDA over the 100% of Budgeted EBITDA benchmark, which in this case equals 5%, is divided by the difference between (a) 110% and (b) 100% (the two
applicable Budgeted EBITDA benchmarks), yielding 50%; 

  

	 	(2)	 	This amount (50%) is then multiplied by the difference between (x) 200% (the Target Bonus at 110% of Budgeted EBITDA) and (y) 100% (the Target Bonus at 100% of
Budgeted EBITDA), which equals 50% of the Executive’s Base Salary as the Target Bonus payable for the increase of 5% over the 100% Budgeted EBITDA Benchmark; 

  

	 	(3)	 	This amount (50% of Base Salary) is then added to the 100% of Base Salary that was earned when Actual EBITDA met the 100% of Budgeted EBITDA Benchmark, which equals an aggregate
total of 150% of the Executive’s Base Salary as the Target Bonus.
