This Separation Agreement and General Release (this “Agreement”) is entered into between Andrew Layman (“Employee”) and IEA Energy Services, LLC. IEA Energy Services, LLC is hereinafter referred to as “IEA” or the “Company,” and includes Infrastructure and Energy Alternatives, Inc. and its subsidiaries but does not include Infrastructure and Energy Alternatives, LLC. Employee and IEA are sometimes collectively referred to as the “Parties”. The Parties agree as follows:

1.Separation Date. Employee’s employment with IEA will separate effective February 13, 2020 (the “Separation Date”). The parties agree that the Employment Agreement between the Company and Employee dated January 25, 2018 (the “Employment Agreement”) is terminated effective as of the Separation Date. Unless otherwise stated herein, the provisions herein shall supersede the terms of the Employment Agreement (including such provisions with respect to severance pay).

2.Separation Pay. IEA will pay the following amounts to Employee:

a.Severance pay in the total gross amount of $400,000 minus tax deductions and withholdings in 12 monthly installments, in accordance with the Company’s normal payroll practices;

b.Employee’s 2019 annual incentive cash bonus earned during 2019 under the 2019 Annual Incentive Compensation Plan (“AICP”) in the lump sum amount of $302,180.00, which amount shall be paid at the same time as the other 2019 AICP awards are paid, which is currently targeted for Friday, March 13, 2020;

c.The annual incentive cash bonus that otherwise would have been payable to Employee for 2020 under Section 4(c) of the Employment Agreement in the lump sum amount of $36,427.00, which amount has been agreed to by the Parties as a reasonable estimate of the 2020 AICP; and,

d. Collectively, the amounts in Section 2(a), (b) and (c) are referred to as the “Separation Pay,” and IEA will pay or commence to pay to Employee the Separation Pay as soon as practicable after Employee signs, dates and returns this Agreement and the Revocation Period (as defined herein) has expired without Employee having exercised his/her revocation rights).

The Separation Pay shall be subject to and conditioned upon Employee’s signing and not revoking this Agreement and his/her ongoing compliance with Sections 6 and 11 of this Agreement. Employee further acknowledges that the Separation Payment described above constitutes full and fair consideration for the release of all claims as described in Section 6 of this Agreement, that the Company is not otherwise obligated to make these payments to him/her, and that they are in addition to any other sums to which he/she is otherwise due. Employee also acknowledges that he/she has received all other forms of compensation, of whatever kind, that may be due to him/her.

3.Vesting of Equity Awards under Long-Term Incentive Plan. Provided that Employee satisfies the requirements to receive the Separation Pay as set forth in Section 2 above and otherwise complies with the terms of this Agreement, then the Company shall cause specified portions of the long-term incentive awards granted to Employee under the Infrastructure and Energy Alternatives, Inc. 2018 Long Term Incentive Plan, as amended (the “LTIP”), to vest in accordance with their terms, subject to the following:

a.13,113 Tranche 1 Options, which represents the one-fourth (1/4) of the Tranche 1 Options granted on September 14, 2018 for vesting on March 26, 2020, will vest on March 10, 2020; and

b.6,887 Tranche 1 Restricted Stock Units granted on September 14, 2018 for vesting on March 26, 2020 will vest on March 26, 2020.

Shares of Common Stock of Infrastructure and Energy Alternatives, Inc. (“IEA, Inc.”) issuable upon the vesting of the award in (b) above shall be subject to withholding for federal and state income tax obligations and all of the applicable terms and conditions of the Plan and the award agreement.

For the avoidance of doubt, the Tranche 1 Options that vest under Section 3(a) above will be exercisable during the thirty (30) day period after the date of this Agreement in accordance with Section 4(b) of the non-qualified option award

agreement dated September 14, 2018 by and between the Company and Employee. Except as set forth above, all unvested long-term incentive awards are hereby forfeited and cancelled effective on the date of this Agreement.

4.Continuation of Medical, Dental, Vision under COBRA; Termination of 401(k) Participation. Any medical, dental, and vision benefits that Employee has in place under Company plans as of the Separation Date will continue through the last day of the month containing the Separation Date. Thereafter, Employee may elect to continue any Company health, dental, and/or vision benefits in which he/she participates as of the Separation Date in accordance with COBRA and the terms and conditions of the applicable plans. Continuation coverage information will be sent to Employee as per COBRA notification requirements following the effective date of benefits termination. Employee’s active participation in the Company’s 401(k) plan will end as of the Separation Date. The Company or its designee will provide Employee with separate information about Employee’s post-separation 401(k) plan rights.

5.Consideration. Employee agrees and acknowledges that the Separation Pay exceeds the value of any compensation or benefits owed to Employee to which Employee is entitled by law, contract, employment policy or otherwise. Further, Employee agrees that the Separation Pay under Section 2 and the vesting of certain LTIP awards under Section 3 shall be the sole consideration payable hereunder or under the Employment Agreement with respect to Employee’s separation from employment. Employee further agrees that he/she has no accrued unused PTO as of the date this Agreement becomes effective (which is that date occurring on the eighth (8^th) day after he/she signs this Agreement, provided that he/she does not revoke within the Revocation Period), and further agrees that no payment will be made to Employee under the Company’s Paid Time Off Policy or otherwise in connection with accrued and unused paid time off.

6.General Release by Employee. Employee releases IEA and the Released Parties (as defined below) from all claims or rights of any kind arising before Employee signs this Agreement. This release of all claims includes, but is not limited to, a release of all claims or rights arising out of or in connection with Employee’s employment with IEA or his separation from employment. This release of all claims also includes a release of any claim or right to further wages, compensation, benefits, divesting of awards under long-term incentive plans, damages, penalties, attorneys’ fees, costs, or expenses of any kind from IEA or any of the other Released Parties. This means that Employee is forever giving up and waiving all claims and rights, known or unknown, Employee may have against IEA or any of the other Released Parties based on any conduct that occurred before Employee signs this Agreement. By waiving and giving up such claims, Employee is releasing IEA and the other Released Parties from any liability or obligation for any expenses, damages, losses, attorneys’ fees or costs Employee might claim based on, among other things, the following:

c.Any company policies, practices, contracts or agreements;

d.The Indiana Wage Payment Act, the Indiana Wage Claims Act, and any policies, practices, laws or agreements governing the payment of wages, commissions or other compensation;

e.Any common law, public policy, contract (whether oral or written, express or implied) or tort law or wrongful termination claim;

f.Any employee benefit plan, other than those benefit plans that Employee has vested rights in as of the Separation Date; and

g.Any laws or agreements that provide for punitive, exemplary or statutory damages or for the payment of attorney fees, costs or expenses.

In addition to these claims being released, Employee acknowledges that he/she has not suffered any physical or mental injuries arising out of his/her employment with IEA or his separation from employment. This release does not waive or release any rights Employee has or may have: (i) under this Agreement; (ii) under any laws providing for continuation of health insurance or that by law cannot be waived or released; or (iii) for indemnification under the Indemnification Agreement between

Employee and IEA, Inc. dated March 26, 2018 or any other indemnification obligations of IEA, Inc. to the Employee under its Certificate of Incorporation or bylaws, as each may be amended from time to time. Nothing in this Agreement shall be construed as changing any existing vested rights as Employee may have under the terms of any claim for vested benefits covered by ERISA.

7.General Release by IEA. In consideration of Employee's agreement to execute the Agreement and thereby release his claims, IEA (for itself and its successors and assigns) releases Employee from any and all claims (including, but not limited to, claims for attorneys’ fees), demands, losses, damages, injuries, agreements, actions, promises or causes of action (known or unknown) which it now has or may later discover or which may hereafter exist against it in connection with or arising directly or indirectly out of or in any way related to any and all matters, transactions, events or other things occurring prior to the date hereof.

9.Non-Admission; Termination of Relationship. This Agreement shall not be construed as or be deemed to constitute an admission on the part of IEA or any of the other Released Parties, and each of the Released Parties specifically denies any liability, wrongdoing or violation of any law, statute, regulation or policy. Employee agrees not to apply for future employment with IEA, or any of its subsidiaries. Employee acknowledges that neither IEA nor any of its affiliates or successors have any obligation, contractual or otherwise, to rehire, reemploy, recall, or hire Employee in the future.

10.Confidentiality. Employee agrees to keep the terms of this Agreement completely confidential, and, except as required by law or as provided herein, Employee will not disclose any information concerning this Agreement, including but not limited to the Separation Pay, to anyone other than Employee’s attorneys, spouse and tax advisors, each of whom Employee will inform of and who will be bound by this confidentiality clause. Infrastructure and Energy Alternatives, Inc. has filed a current report on Form 8-K announcing the separation. Nothing in this confidentiality statement prohibits Employee from reporting possible violations of federal, state, or local law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or making other disclosures (including but not limited to providing documents or other information ) that are protected under the whistleblower provisions of federal law or regulation. Employee does not need the prior authorization of IEA to make any such reports or disclosures, and Employee is not required to notify IEA that he/she has made such reports or disclosures. Employee is also not limited in his/her right to receive an award for information provided to any government agency or entity.

As provided by federal law (18 U.S.C. §1833), Employee understands that he/she will not be held criminally or civilly liable under any federal or state trade secret law for disclosure of a trade secret that is made by him/her: (a) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or (b) in a complaint or other document filed by Employee in a lawsuit or other proceeding, on the condition that such filing is made under seal.

Specifically, Employee reaffirms and agrees to abide by Sections 5, 6, 7, 8, 9, 10 and 13 of the Employment Agreement. These obligations are irrevocable, notwithstanding the revocation rights as set forth in Section 21, below. Notwithstanding the foregoing, the Parties hereby agree that the Restriction Period for the non-competition obligations in Section 5(a)(i) of the Employment Agreement shall be limited to twelve (12) months. The Parties acknowledge and agree that all other provisions of the above referenced Sections of Employee’s Employment Agreement remain unchanged and in full force and effect.

12.Severability. Employee understands, and it is his/her intent, that in the event this Agreement is ever held to be invalid or unenforceable (in whole or in part) as to any particular type of claim or charge or as to any particular circumstances, it shall remain fully valid and enforceable as to all other claims, charges, and circumstances.

13.Exclusions from Release. Employee understand that his/her release of all claims under this Agreement do not include any rights or claims that may arise after the date this Agreement becomes effective (which is that date occurring on

the eighth (8^th) day after he/she signs this Agreement, provided that he/she does not revoke within the Revocation Period). Employee understands that he/she does not waive future claims. Also, nothing in this Agreement (including the confidentiality provision above) prevents Employee from filing a charge with the Equal Employment Opportunity Commission (“EEOC”), otherwise cooperating with or providing information to the EEOC or from providing truthful information when testifying under oath or where there is a legal duty to provide truthful information.

Employee acknowledges that he/she has the right to file a charge alleging a violation of the ADEA with any administrative agency and/or to challenge the validity of the waiver and release of any claim he/she might have under the ADEA without either: (a) repaying to IEA the amounts paid by it to him/her or on his/her behalf under this Agreement; or (b) paying to IEA any other monetary amounts (such as attorney's fees and/or damages).

14.Return of Information and Equipment. Employee agrees that the Company-owned vehicle that is in his/her possession, custody, or control will be delivered or made available for delivery to IEA as of the Separation Date. Employee further represents and warrants that Employee (a) has returned to IEA all documents or other tangible and intangible information or materials of IEA and the Released Parties (regardless of how stored or maintained) used, prepared or collected by Employee as part of Employee’s employment with IEA (cumulatively, “IEA Information”), whether or not IEA Information constitutes confidential information, including all copies thereof and (b) Employee has irretrievably deleted any IEA Information in electronic format possessed or accessible by Employee on any personal computers, smart phones, data storage devices, mobile devices, cloud based data storage, or internet based e-mail system, such as gmail or yahoo mail, unless otherwise instructed in writing by IEA. This includes ceasing to represent IEA on any social media or job posting platforms as Employee’s current employer. These obligations are irrevocable, notwithstanding the revocation rights as set forth in Section 21 below.

15.Cooperation with Company After Separation Date. If requested by the Company during the six-month period following the Separation Date, Employee agrees to provide timely and satisfactory assistance not to exceed one (1) hour per week in regard to the transition of business matters or issues that arise within Employee’s areas of responsibility. Employee agrees to respond in a timely and effective manner to questions that he/she may receive from the Company with regard to any matters within his/her knowledge or areas of responsibility during his/her employment with the Company, and he/she acknowledges that such assistance may be desired by the Company with regard to transition or other ongoing matters. Employee agrees to fully and timely cooperate with the Company's requests for such assistance.

16.Entire Agreement. This Agreement (and the ongoing obligations in the Employment Agreement listed in Section 11 of this Agreement) contains the entire agreement between Employee and IEA relating to the separation Employee’s employment, and Employee may not rely on any prior agreements or discussions.
