Following the 12 month anniversary of the Separation Date, if Executive's assistance is required under this provision, the Company will reimburse Executive for any lost wages or leave, in addition to any reasonable expenses, Executive incurs in assisting ICF in any such matter.

f.

Confidentiality. Executive acknowledges that, as part of Executive's employment, Executive had access to information of a nature not generally disclosed to the public, and Executive agrees to keep confidential and not disclose to anyone, the business, proprietary, and trade secret information in Executive's possession, as well as any personal, confidential, or otherwise proprietary information regarding the Company's employees, customers and clients, and/or the Company's personnel practices and related matters.

Compliance with Applicable Laws/Clawback as Per the Letter Agreement.

a.

The terms “Cause”, “Clawback Event”, “Code”, “Excess Incentive Award”, and “Incentive Plan” below shall have the meanings defined in the Letter Agreement.

Taxes and other applicable withholdings will be withheld from payments and benefits under this Agreement to the extent the Company determines they are allowed or required by law. Executive is solely responsible for the payment of any tax liability, including any taxes and penalties arising under Section 409A of the Code that may result from any payments or benefits that Executive receives pursuant to this Agreement. The Company shall not have any obligation to pay, mitigate, or protect Executive from any such tax liabilities.

c.

The provisions of this Agreement are intended to comply with, or be exempt from, Code Section 409A, and the Company shall have complete and sole discretion to interpret and construe this Agreement and any associated documents in any manner that complies with, or complies with an exemption from (or otherwise conforms them to), the requirements of Code Section 409A including, without limitation, imposing any 6-month delay that may be required for severance payments and benefits under this Agreement to Executive if (i) such constitute nonqualified deferred compensation subject to Code Section 409A, and (ii) Executive is classified as a "specified employee" under Code Section 409A. The Company reserves the right (including the right to delegate such right) to unilaterally amend this Agreement without the consent of Executive or anyone else in order to maintain an exemption from (or conformity with) Code Section 409A. Executive's execution of this Agreement constitutes acknowledgement and consent to such rights of the Company. A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits that are considered nonqualified deferred compensation under Code Section 409A upon or following a termination of employment unless such termination is also a "separation from service" within the meaning of Code Section 409A, and, for purposes of any such provision of this Agreement, references to a "termination," "termination of employment" or like terms shall mean "separation from service." The determination of whether and when a separation from service has occurred for purposes of this Agreement shall be made in accordance with the presumptions set forth in Section 1.409A-1(h) of the Treasury Regulations.

d.

Each payment of Executive's severance or other benefits pursuant to this Agreement shall be deemed to be a separate payment for purposes of applying the provisions of Code Section 409A.

Reg. §1.409A-1(b)(9)(iii)(A)), such payment shall not be made prior to the date that is the earliest of (i) 6 months after the date of Executive's separation from service; (ii) Executive's death; or (iii) such other date that will cause such payment to Executive not to be subject to any additional tax imposed pursuant to the provisions of Section 409A.

e.

Executive acknowledges and agrees that, notwithstanding any other provisions in this Agreement, any compensation paid to Executive pursuant to this Agreement that constitutes recoverable compensation under any applicable law, government regulation, or stock exchange listing requirement or under the Company’s Compensation Recovery Policy (or any successor policy thereto), as any of them may be in effect from time to time, shall be subject to such compensation recovery or reimbursement requirements as thought such requirements were expressly set forth in this Agreement. In the event of any conflict between any applicable law, government regulation, or stock exchange listing requirement or under the Company’s Compensation Recovery Policy and this Agreement, the requirements of such law, government regulation, or stock exchange listing requirement or the Company’s Compensation Recovery Policy shall control. Executive agrees to cooperate in good faith with the Company and the Board with respect to any such recovery or reimbursement (including by executing any consent that may be required to offset future payments by the Company or to permit the deductions of any amounts owed to the Company from Executive’s wages).

f.

To the extent required by Code Section 409A, each reimbursement or in-kind benefit provided under this Agreement will be provided in accordance with the following: (i) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during each calendar year cannot affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year; (ii) any reimbursement of an eligible expense shall be paid to Executive on or before the last day of the calendar year following the calendar year in which the expense was incurred; and (iii) any right to reimbursements or in-kind benefits under this Agreement shall not be subject to liquidation or exchange for another benefit.

This Agreement may not be amended or modified except by an agreement in writing signed by both parties. The drafting of this Agreement shall be deemed a mutual endeavor by all parties and shall not be construed against any single party as the drafter.

Facsimile signatures shall be considered originals. The parties acknowledge and agree to use and accept electronic signatures, and this Agreement may be executed using electronic signatures.
