 Exhibit 10.2 
 ICF INTERNATIONAL, INC. 
 RESTRICTED STOCK AWARD AGREEMENT 
 (Non-Employee Director Award) 
 This
Restricted Stock Award Agreement (this “Agreement”) is by and between ICF International, Inc., a Delaware corporation (the “Corporation”), and Richard M. Feldt (the “Participant”), a non-employee
director of the Corporation, and is effective as of the closing of business on March 14, 2008 (the “Effective Date”). 
 1. Award of Restricted Stock. Subject to the provisions of the ICF International, Inc. 2006 Long-Term Equity Incentive Plan (the “Plan”) and this Agreement, the Corporation hereby grants to the Participant Five
Thousand Ninety Six (5,096) shares (the “Award”) of the Corporation’s Common Stock, par value $0.001 per share (the “Common Stock”), to which the restrictions referred to in Section 2 (the
“Vesting Conditions”) attach (the “Restricted Stock”). 
 2. Vesting Conditions. 
 (a) Vesting Schedule. The Restricted Stock shall be initially unvested (the unvested shares
of Restricted Stock are referred to in this Agreement as the “Unvested Shares”) and shall vest, if at all, as provided in this Section 2 over a three (3) year period measured from the Effective Date (the “Vesting
Period”). Except as otherwise provided in Section 2(c) below, thirty-three and  1/3 percent (33 1/3%) of the Restricted Stock shall vest upon the date that is 366 days after the Effective Date, thirty-three and  1/3 percent (33 1/3%) of the Restricted Stock shall vest on the second anniversary of the Effective Date, and thirty-three and  1/3
percent (33 1/3%) of the Restricted Stock shall vest on the third anniversary of the Effective Date (each, a
“Vesting Date”). 
 (b) Rounding. The number of shares of Restricted Stock
vesting as of a particular Vesting Date shall be rounded down to the nearest whole share; provided, however, that all remaining Unvested Shares shall vest completely on the final Vesting Date. 
 (c) Other Vesting. Notwithstanding anything to the contrary contained in this Section 2, all of the Restricted Stock shall vest immediately
upon the occurrence of a Change in Control (as defined in Section 8 hereof) of the Corporation at any time prior to the satisfaction of the Vesting Conditions. 
 3. Rights During Vesting Period. The Participant generally shall have the rights and privileges of a stockholder as to the Restricted Stock, including the right to receive cash dividends and the right to vote.
However, notwithstanding any other provision hereof, the following restrictions shall apply to shares of Restricted Stock prior to satisfaction of the Vesting Conditions as to those shares: (a) the Participant shall not be entitled to delivery
of a certificate for the Restricted Stock until the satisfaction of the Vesting Conditions; (b) none of the Restricted Stock may be sold, transferred (except by will or the laws of descent and distribution), assigned, pledged or otherwise
encumbered or disposed of prior to satisfaction of the Vesting Conditions; and (c) except as otherwise expressly provided herein and in the Plan, the Participant shall forfeit and immediately transfer back to the Corporation without 

 
payment all of the Restricted Stock, and all rights of the Participant to such Restricted Stock shall terminate without further obligation on the part of the
Corporation, if and when the Participant ceases to be a director of the Corporation prior to the satisfaction of the Vesting Conditions. As a condition of the Award, the Corporation may require the Participant to deliver to the Corporation a duly
signed stock power, endorsed in blank, with respect to the shares of Common Stock subject to the Award. 
 4. Satisfaction of Vesting
Conditions. Upon the satisfaction of the Vesting Conditions as to particular shares of Restricted Stock, the restrictions on the applicable number of shares of Restricted Stock shall terminate and a stock certificate for such number of shares of
Common Stock shall be delivered, free and clear of all such restrictions, to the Participant or, subject to Section 5, the Participant’s beneficiary or estate, as the case may be, subject to the provisions of Sections 7 and 8(e). The
Corporation shall not be required to deliver any fractional share of Common Stock, but will pay, in lieu thereof, the fair market value of such fractional share to the Participant or the Participant’s beneficiary or estate, as the case may be.
The Corporation shall pay any original issue tax that may be due upon the issuance of the Restricted Stock and all other costs incurred by the Corporation in issuing such shares of Common Stock. 
 5. Nontransferability of Restricted Stock. The Restricted Stock is not transferrable by the Participant prior to the satisfaction of the Vesting
Conditions except by will or the laws of descent and distribution. Without limiting the generality of the foregoing, prior to the expiration of the Vesting Conditions, the Award and Restricted Stock may not be sold, transferred except as aforesaid,
assigned, pledged, or otherwise encumbered or disposed of, shall not be assignable by operation of law, and shall not be subject to execution, attachment or similar process. Any attempted sale, transfer, pledge, assignment or other encumbrance or
disposition of the Restricted Stock contrary to the provisions hereof, or the levy of any execution, attachment or similar process upon the Restricted Stock, shall be null and void and without effect. 
 6. Reorganization or Liquidation of the Corporation. In the event the Corporation is succeeded by another corporation in a reorganization, which
term includes a merger, consolidation, acquisition of all or substantially all of the assets or voting stock of the Corporation, or other extraordinary transaction with similar effect, the Participant shall be entitled to receive (subject to any
required action by stockholders) such securities of the surviving or resulting corporation or other consideration as the board of directors of such corporation shall determine to be as nearly equivalent as practicable to the nearest whole number and
class of shares of stock or other securities or other consideration to which the Participant would have been entitled under the terms of such reorganization (without adjustment for any fractional interest thereby eliminated), as if, immediately
prior to such event, the Participant had been the holder of record of the number of shares of Common Stock which were then Restricted Stock without any restriction whatsoever. Any such shares of stock or other securities issued to the Participant in
connection with any such reorganization shall, after any such reorganization, be deemed to be Restricted Stock for all purposes of this Agreement and the Plan. 
  

 - 2 - 

 7. Compliance with Securities Laws; Legend on Share Certificates. 
 (a) As of the Effective Date, the Restricted Stock has not been registered under the Securities Act of 1933, as amended (the “Securities
Act”), or under any applicable state securities laws (the Securities Act and such state laws being hereinafter sometimes referred to as the “Securities Laws”). The Restricted Stock shall not be transferrable except pursuant
to the provisions of the Securities Laws. The Participant represents that the Participant (i) is acquiring the Restricted Stock for the Participant’s own account and not with a view to reselling, splitting, sharing or otherwise
participating in a distribution thereof in violation of any Securities Laws, (ii) understands that the effect of such representation is that the Restricted Stock must be held indefinitely unless subsequently registered under the Securities Laws
or an exemption from such registration is available at the time of any proposed sale or other transfer thereof, (iii) understands that the Corporation is under no obligation to register the Restricted Stock for resale, and (iv) is fully
familiar with the circumstances under which the Participant is required to hold the Restricted Stock and the limitations upon transfer or other disposition thereof. 
 (b) The Participant agrees that each certificate for the Restricted Stock shall be stamped or otherwise imprinted with legends in substantially the following forms: 
 (i) The shares represented hereby have not been registered under the Securities Act of 1933, as amended (the “Act”), or under the state
securities or blue sky laws of any state. Such shares may not be sold or transferred except pursuant to an effective registration statement under the Act or an opinion of counsel satisfactory to the Corporation that such registration is not
required. 
 (ii) The sale or other transfer of the shares represented hereby is subject to certain restrictions contained in a certain
Restricted Stock Award Agreement by and between the registered owner and ICF International, Inc., as the same may be amended from time to time, to which reference is hereby made for a full statement of provisions thereof. A copy of said Agreement
will be furnished to any stockholder on request and writing in without charge. 
 8. Change of Control. As used herein, a
“Change in Control” of the Corporation means, and shall be deemed to have occurred upon, any of the following events: 
 (a)
The acquisition by any person (as defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and used in Sections 13(d) and 14(d) thereof, including a group as defined in
Section 13(d) thereof) (other than persons acting in concert as of August 31, 2006 who, as of such date, beneficially owned more than twenty percent (20%) or more of the securities entitled to vote generally in the election of
directors of the Corporation), of beneficial ownership (as defined in Rule 

  

 - 3 - 

 
13d-3 of the General Rules and Regulations under the Exchange Act) of securities representing thirty-five percent (35%) or more of the securities
entitled to vote generally in the election of directors of the Corporation, provided, however, that the following acquisitions shall not constitute a Change in Control for purposes of this subparagraph (a): (i) any acquisition
directly from the Corporation; (ii) any acquisition by the Corporation or any of its Subsidiaries; (iii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Corporation or any of its Subsidiaries;
or (iv) any acquisition by any corporation pursuant to a transaction which complies with clauses (i), (ii) and (iii) of subparagraph (c) below; or 
 (b) Individuals who, as of August 31, 2006, constitute the board of directors of the Corporation (the “Incumbent Board”) cease for any reason to constitute at least a majority of the board of
directors of the Corporation; provided, however, that any individual who becomes a director of the Corporation subsequent to August 31, 2006 and whose election, or whose nomination for election by the Corporation’s
stockholders, to the board of directors was either (i) approved by a vote of at least a majority of the directors then comprising the Incumbent Board or (ii) recommended by a nominating committee comprised entirely of directors who are
then Incumbent Board members shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of either an actual or
threatened election contest (as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act), other actual or threatened solicitation of proxies or consents or an actual or threatened tender offer; or 
 (c) Consummation of a reorganization, merger, or consolidation or sale or other disposition of all or substantially all of the assets of the Corporation
(a “Business Combination”), in each case unless following such Business Combination, (i) all or substantially all of the persons who were the Beneficial Owners (“Beneficial Owners” having the meaning used in
Rule 13d-3 promulgated under the Exchange Act), respectively, of the outstanding shares and outstanding securities entitled to voted generally in the election of directors immediately prior to such Business Combination own, directly or indirectly,
more than fifty percent (50%) of the combined voting power of the then outstanding securities entitled to vote generally in the election of directors of the Corporation, as the case may be, of the entity resulting from the Business Combination
(including, without limitation, an entity which, as a result of such transaction, owns the Corporation or all or substantially all of the Corporation’s assets either directly or through one or more subsidiaries) in substantially the same
proportions as their ownership, immediately prior to such Business Combination, of the outstanding securities entitled to vote generally in the election of directors (provided, however, that for purposes of this clause (i) any
shares of common stock or such voting securities of such resulting entity received by such Beneficial Owners in such Business Combination other than as the result of such Beneficial Owners’ ownership of outstanding shares or such outstanding
voting securities immediately prior to such Business Combination shall not be considered to be owned by such Beneficial Owners for the purposes of calculating their percentage of ownership of the outstanding common stock and voting power of the
resulting entity); (ii) no person (excluding any entity resulting from such Business Combination or any employee benefit plan (or related trust) of the Corporation or such entity resulting from the Business Combination) beneficially owns,
directly or indirectly, thirty-five percent (35%) or more of the combined voting power of the then outstanding securities entitled to vote generally in the election of directors of 

  

 - 4 - 

 
such entity resulting from the Business Combination unless such person owned thirty-five percent (35%) or more of the outstanding shares or outstanding
securities entitled to vote generally in the election of directors immediately prior to the Business Combination; and (iii) at least a majority of the members of the board of directors of the entity resulting from such Business Combination were
members of the Incumbent Board at the time of the execution of the initial agreement, or the action of the board of directors, providing for such Business Combination; or 
 (d) Approval by the Corporation’s stockholders of a complete liquidation or dissolution of the Corporation. 
 For
purposes of clause (c), any person who acquires outstanding securities entitled to vote generally in the election of directors of the entity resulting from the Business Combination by virtue of ownership, prior to such Business Combination, of such
voting securities of both the Corporation and the entity or entities with which the Corporation is combined shall be treated as two persons after the Business Combination, who shall be treated as owning such outstanding voting securities of the
entity resulting from the Business Combination by virtue of ownership, prior to such Business Combination of, respectively, such outstanding voting securities of the Corporation, and of the entity or entities with which the Corporation is combined.

 ICF INTERNATIONAL, INC. 
 NONQUALIFIED DEFERRED COMPENSATION PLAN 
 (Effective May 1, 2008) 

 Preamble 
 The
ICF International, Inc. Nonqualified Deferred Compensation Plan (the “Plan”) is hereby established, effective May 1, 2008, by ICF International, Inc. (the “Company”) in order to provide certain benefits to a select group of
management or highly compensated employees who contribute materially to the continued growth, development and future business success of the Company and its subsidiaries. The Plan shall be unfunded for tax purposes and for purposes of Title I of
ERISA. 
 The Plan is intended to comply with all applicable law, including Section 409A of the Code (as defined below) and shall be
operated and interpreted in accordance with such intention. Moreover, in order to comply with the requirements of said Section 409A, certain transition relief provided under Notice 2007-86, as described more fully in Appendix A of the Plan, may
be provided to Participants. 
 ARTICLE I 
 DEFINITIONS AND CONSTRUCTION 
  

	1.1	Definitions. 

 For the purposes of the Plan,
unless otherwise clearly apparent from the context, the following phrases or terms shall have the following indicated meanings: 
  

	 	(1)	“Account Balance” shall mean, with respect to a Participant, an entry on the records of the Employer equal to the sum of the Participant’s Annual Accounts. The
Account Balance shall be a bookkeeping entry only and shall be utilized solely as a device for the measurement and determination of the amounts to be paid to a Participant, or his or her designated Beneficiary, pursuant to the Plan.

  

	 	(2)	“Annual Account” shall mean, with respect to a Participant for a Plan Year, an entry on the records of the Employer equal to (a) the sum of the
Participant’s Annual Deferral Amount and Company Contribution Amount for such Plan Year, plus (b) amounts credited or debited to such amounts in accordance with the applicable provisions of the Plan, less (c) all distributions made to
the Participant or his or her Beneficiary in accordance with the applicable provisions of the Plan that relate to the Annual Account for such Plan Year. The Annual Account shall be a bookkeeping entry only and shall be utilized solely as a device
for the measurement and determination of the amounts to be paid to a Participant, or his or her designated Beneficiary. 

  

	 	(3)	“Annual Deferral Amount” shall mean the portion of a Participant’s Base Salary, Bonus and Commissions that a Participant defers in accordance with
Article III for any one Plan Year, without regard to whether such amounts are withheld and credited during such Plan Year. 

  

 - 1 - 

	 	(4)	“Annual Installment Method” shall mean the method used to determine the amount of each payment due to a Participant who has elected to receive a benefit over a
period of years in accordance with the applicable provisions of the Plan. The amount of each annual payment due to the Participant shall be calculated by multiplying the balance of the Participant’s benefit by a fraction, the numerator of which
is one and the denominator of which is the remaining number of annual payments due the Participant. The amount of the first annual payment shall be determined as of the close of business on the Participant’s Benefit Distribution Date, (or, in
the event such Benefit Distribution Date is not a business day, the first annual payment shall be valued as of the close of business of the next business day immediately following such Benefit Distribution Date), and the amount of each subsequent
annual payment shall be calculated as of each anniversary of such Benefit Distribution Date. For purposes of the Plan, the right to receive a benefit payment in annual installments shall be treated as the entitlement to a single payment.

  

	 	(5)	“Base Salary” shall mean the annual cash compensation relating to services performed during any Plan Year and designated as “base salary” by the Employer,
excluding, however, distributions from nonqualified deferred compensation plans, bonuses, commissions, overtime, fringe benefits, income from equity incentive plans (including stock options, restricted stock, stock appreciation rights, and stock
bonuses), relocation reimbursements, non-cash incentive payments, and non-monetary awards, as well as automobile and other allowances (whether or not such allowances are included in the Employee’s gross income) paid to a Participant for
employment services rendered. Base Salary shall be calculated before reduction for compensation voluntarily deferred or contributed by or on behalf of the Participant pursuant to all qualified or nonqualified plans of the Employer and shall include
amounts not otherwise included in the Participant’s gross income due to deferrals under Code Sections 125, 402(e)(3), 402(h), or 403(b) to plans established by an Employer; provided, however, that all such amounts shall be included in such
compensation only to the extent that had there been no such plan, the amount would have been payable in cash to the Employee. 

  

	 	(6)	“Beneficiary” shall mean one or more persons, trusts, estates or other entities, designated in accordance with Article IX, as entitled to receive benefits
under the Plan upon the death of a Participant. 

  

	 	(7)	“Beneficiary Designation Form” shall mean the form specified from time to time by the Committee for a Participant to complete and return to the Committee in order
to designate one or more Beneficiaries. 

  

	 	(8)	“Benefit Distribution Date” shall mean the date upon which all or an objectively determinable portion of a Participant’s vested benefits will become eligible
for distribution under the Plan. Except as otherwise provided in the Plan, a Participant’s Benefit Distribution Date shall be determined based on the earliest to occur of an event or scheduled date set forth in Articles IV through VIII, as
applicable. 

  

 - 2 - 

	 	(9)	“Board” shall mean the board of directors of the Company. 

  

	 	(10)	“Bonus” shall mean, for any particular Plan Year, the amount of any cash compensation, in addition to Base Salary and Commissions, earned by a Participant under any
Employer’s annual cash bonus and cash incentive plans. 

  

	 	(11)	“Change in Control” shall mean the occurrence of a “change in the ownership,” a “change in the effective control” or a “change in the
ownership of a substantial portion of the assets” of the Company that is a “change in control” under Code Section 409A. 

  

	 	(12)	“Code” shall mean the Internal Revenue Code of 1986 as well as applicable Treasury regulations and guidance, as may be amended from time to time.

 ARTICLE III 
 DEFERRALS, COMPANY CONTRIBUTION AMOUNTS, 
 VESTING AND WITHHOLDING TAXES

  

	3.1	Deferrals.  

  

	 	(a)	Annual Deferral Amount. For each Plan Year, a Participant may elect to defer, as his or her Annual Deferral Amount, a percentage of his or her Base Salary, Bonus
and/or Commissions up to the following maximum percentages for each deferral elected: 

  

				
	 Deferral
	  	Maximum Percentage Allowed	 
	 Base Salary
	  	80	%
	 Bonus
	  	100	%
	 Commissions
	  	100	%

 In the event that an election is made for less than 1% or if no election is made for a particular
type of deferral, the amount deferred shall be 0%. If an election is made for more than the stated maximum percentage, the amount deferred shall be the stated maximum percentage. 
  

	 	(b)	Short Plan Year. Notwithstanding the foregoing, in the case of (i) the first Plan Year in which the Plan is in effect or (ii) an individual first becoming a
Participant after the first day of a Plan Year, then to the extent required by Section 3.2 and Code Section 409A, the maximum amount of the Participant’s Base Salary, Bonus or Commissions that may be deferred by the Participant for
the Plan Year shall be determined by applying the percentages set forth in Section 3.1(a) to the portion of such compensation attributable to services performed after the date that the Participant’s deferral election is made and submitted
to the Committee. 

  

	3.2	Timing of Deferral Elections; Effect of Election Form. 

  

	 	 (a)
	 General Timing Rule for Deferral Elections. Except as otherwise provided in this Section 3.2, in
order for a Participant to make a valid election to defer Base Salary, Bonus and/or Commissions, the Participant must submit an Election Form on or before the deadline established by the Committee, which in no event shall be later than the
December 31st preceding the Plan Year in which such compensation will be earned. Any deferral election made in accordance with this
Section 3.2(a) shall be irrevocable as of such December 31st; provided, however, that if the Committee permits or requires Participants to
make a deferral election by the deadline described above for an amount that qualifies as Performance-Based Compensation, the Committee may permit a Participant to subsequently change his or her deferral election for such compensation by submitting a
new Election Form in accordance with Section 3.2(c) below. 

  

	 	(b)	 Timing of Deferral Elections for Newly Eligible Plan Participants. A selected Employee who first becomes eligible to participate in the Plan on or
after the beginning of a Plan Year, as determined in accordance with Code Section 409A 

  

 - 7 - 

	 	 
and the “plan aggregation” rules provided in Code Section 409A, may be permitted to make an election to defer the portion of his or her Base
Salary, Bonus and/or Commissions attributable to services to be performed after such election; provided that the Participant submits an Election Form on or before the deadline established by the Committee, which in no event shall be later than 30
days after the Participant first becomes eligible to participate in the Plan. If a deferral election made in accordance with this Section 3.2(b) relates to compensation earned based upon a specified performance period, the amount eligible for
deferral shall be equal to (i) the total amount of compensation for the performance period, multiplied by (ii) a fraction, the numerator of which is the number of days remaining in the service period after the Participant’s deferral
election is made, and the denominator of which is the total number of days in the performance period. Any deferral election made in accordance with this Section 3.2(b) shall become irrevocable no later than the 30th day after the date the selected Employee becomes eligible to participate in the Plan. 

  

	 	(c)	Timing of Deferral Elections for Performance-Based Compensation. Subject to the limitations described below, the Committee may determine that an irrevocable deferral
election for an amount that qualifies as Performance-Based Compensation may be made by submitting an Election Form on or before the deadline established by the Committee, which in no event shall be later than 6 months before the end of the
performance period. In order for a Participant to be eligible to make a deferral election for Performance-Based Compensation in accordance with the deadline established pursuant to this Section 3.2(c), the Participant must have performed
services continuously from the later of (i) the beginning of the performance period for such compensation, or (ii) the date upon which the performance criteria for such compensation are established, through the date upon which the
Participant makes the deferral election for such compensation. In no event shall a deferral election submitted under this Section 3.2(c) be permitted to apply to any amount of Performance-Based Compensation that has become readily
ascertainable. 

  

	 	 (d)
	 Timing Rule for Deferral of Compensation Subject to Risk of Forfeiture. With respect to compensation
(i) to which a Participant has a legally binding right to payment in a subsequent year, and (ii) that is subject to a forfeiture condition requiring the Participant’s continued services for a period of at least 12 months from the date
the Participant obtains the legally binding right, the Committee may determine that an irrevocable deferral election for such compensation may be made by timely delivering an Election Form to the Committee in accordance with its rules and
procedures, no later than the 30th day after the Participant obtains the legally binding right to the compensation; provided that the election is
made at least 12 months in advance of the earliest date at which the forfeiture condition could lapse, as determined in accordance with Code Section 409A. Any deferral election(s) made in accordance with this Section 3.2(d) shall become
irrevocable no later than the 30th day after the Participant obtains the legally binding right to the compensation subject to such deferral
election(s).

	3.3	Withholding and Crediting of Annual Deferral Amounts. For each Plan Year, the Base Salary portion of an Annual Deferral Amount shall be withheld from each regularly
scheduled Base Salary payroll in equal amounts, as adjusted from time to time for increases and decreases in Base Salary. The Bonus and/or Commissions portion of an Annual Deferral Amount shall be withheld at the time the Bonus or Commissions are or
otherwise would be paid to the Participant, whether or not this occurs during the Plan Year itself. Annual Deferral Amounts shall be credited to the Participant’s Annual Account for such Plan Year at the time such amounts would otherwise have
been paid to the Participant. 

  

	3.4	Company Contribution Amount. 

  

	 	(a)	For each Plan Year, an Employer may be required to credit amounts to a Participant’s Annual Account in accordance with employment or other agreements entered into between the
Participant and the Employer, which amounts shall be part of the Participant’s Company Contribution Amount for such Plan Year. Such amounts shall be credited to the Participant’s Annual Account for the applicable Plan Year on the date or
dates prescribed by such agreements. Notwithstanding the foregoing, such amounts shall only be credited under the Plan if such crediting will not cause the Plan to fail to comply with Code Section 409A. 

  

	 	(b)	For each Plan Year, an Employer, in its sole discretion, may, but is not required to, credit any amount it desires to any Participant’s Annual Account under the Plan, which
amount shall be part of the Participant’s Company Contribution Amount for such Plan Year. The amount so credited to a Participant may be smaller or larger than the amount credited to any other Participant, and the amount credited to any
Participant for a Plan Year may be zero, even though one or more other Participants receive a Company Contribution Amount for that Plan Year. The Company Contribution Amount described in this Section 3.4(b), if any, shall be credited to the
Participant’s Annual Account for the applicable Plan Year on a date or dates to be determined by the Committee. 

  

	 	(c)	If not otherwise specified in the Participant’s employment or other agreement entered into between the Participant and the Employer, the amount (or the method or formula for
determining the amount) of a Participant’s Company Contribution Amount shall be set forth in writing in one or more documents, which shall be deemed to be incorporated into the Plan in accordance with Paragraph (27) of Section 1.1, no
later than the date on which such Company Contribution Amount is credited to the applicable Annual Account of the Participant. 

  

	3.5	Vesting. 

  

	 	(a)	A Participant shall at all times be 100% vested in the portion of his or her Account Balance attributable to Annual Deferral Amounts, plus amounts credited or debited on such
amounts pursuant to Section 3.6.

If not addressed in such agreements, a Participant shall vest in each Company Contribution Amount, plus amounts credited or debited on such amounts pursuant to Section 3.6, on the anniversary of the date on which such Company Contribution
Amount was credited to the Participant’s Account Balance, in accordance with the following schedule; provided, however, that the Participant must be in the service of an Employer as an Employee on such anniversary to receive vesting credit:

  

				
	 Time Elapsed Following Crediting of Company Contribution Amount
	  	Vested Percentage	 
	 Less than 1 year
	  	0	%
	 1 year or more, but less than 2 years
	  	33	%
	 2 years or more, but less than 3 years
	  	67	%
	 3 years or more
	  	100	%

 A new vesting schedule shall apply to each Company Contribution Amount credited to the
Participant’s Account Balance. 
  

	 	(c)	Notwithstanding anything to the contrary contained in this Section 3.5, in the event of a Participant’s Disability, death prior to Separation from Service, attainment of
Normal Retirement Age, or a Separation from Service due to termination of employment by the Employer within one year following a Change in Control, any amounts that are not vested in accordance with Section 3.5(b) above, shall immediately
become 100% vested.  

  

	3.6	Crediting and Debiting of Account Balances. In accordance with, and subject to, the rules and procedures that are established from time to time by the Committee, in
its sole discretion, amounts shall be credited or debited to a Participant’s Account Balance in accordance with the following provisions: 

  

	 	(a)	Measurement Funds. The Participant may elect one or more of the measurement funds selected by the Committee, in its sole discretion, which are based on certain mutual
funds (the “Measurement Funds”), for the purpose of crediting or debiting additional amounts to his or her Account Balance. As necessary, the Committee may, in its sole discretion, discontinue, substitute or add a Measurement Fund. Each
such action shall take effect as of the first day of the first calendar quarter that begins at least 30 days after the day on which the Committee gives Participants advance written notice of such change. 

  

	 	(b)	 Election of Measurement Funds. A Participant, in connection with his or her initial deferral election in accordance with Section 3.2 above, shall
elect, on the Election Form, one or more Measurement Fund(s) (as described in Section 3.6(a) above) to be used to determine the value of his Account Balance. If a Participant does not elect any of the Measurement Funds as described in the
previous sentence, the Participant’s Account Balance shall automatically be allocated into the lowest-risk Measurement Fund as of such allocation date, as determined by the Committee, in its sole 

  

 - 10 - 

	 	 
discretion. The Participant may (but is not required to) elect, in the manner prescribed by the Committee, to add or delete one or more Measurement Fund(s)
to be used to determine the value of his or her Account Balance, and/or to change the portion of his or her Account Balance allocated to each previously or newly elected Measurement Fund. If an election is made in accordance with the previous
sentence, it shall apply as of the first business day deemed reasonably practicable by the Committee, in its sole discretion, and shall continue thereafter, unless changed in accordance with the previous sentence, so long as the Participant has an
Account Balance under the Plan. Notwithstanding the foregoing, the Committee, in its sole discretion, may impose limitations on the frequency with which one or more of the Measurement Funds elected in accordance with this Section 3.6(b) may be
added or deleted by such Participant; furthermore, the Committee, in its sole discretion, may impose limitations on the frequency with which the Participant may change the portion of his or her Account Balance allocated to each previously or newly
elected Measurement Fund. 

  

	 	(c)	Proportionate Allocation. In making any election described in Section 3.6(b) above, the Participant shall specify on the Election Form, in increments of one
percent (1%), the percentage of his or her Account Balance or Measurement Fund, as applicable, to be allocated/reallocated. 

  

	 	(d)	Crediting or Debiting Method. The performance of each Measurement Fund (either positive or negative) shall be determined on a daily basis based on the manner in
which such Participant’s Account Balance has been hypothetically allocated among the Measurement Funds by the Participant pursuant to Section 3.6(a). 

  

	 	(e)	No Actual Investment. Notwithstanding any other provision of the Plan that may be interpreted to the contrary, the Measurement Funds shall be used for measurement
purposes only. Elections of any such Measurement Fund by Participants, and the crediting or debiting of such amounts to a Participant’s Account Balance shall not be considered or construed in any manner as an actual investment of his or her
Account Balance in any such Measurement Fund. In the event that the Company, in its own discretion, decides to invest funds in any or all of the investments on which the Measurement Funds are based, no Participant shall have any rights in or to such
investments themselves. Without limiting the foregoing, a Participant’s Account Balance shall at all times be a bookkeeping entry only and shall not represent any investment made on his or her behalf by the Company. Participants shall at all
times remain unsecured creditors of the Company.

	 	(a)	 Annual Deferral Amounts. For each Plan Year in which an Annual Deferral Amount is being withheld from a Participant, the Participant’s Employer

taxes on such Annual Deferral Amount. If necessary, the Committee may reduce, in accordance with Code Section 409A, the Annual Deferral Account in order to comply with this Section 3.7. 

  

	 	(b)	Company Contribution Amounts. When a Participant becomes vested in a portion of his or her Account Balance attributable to any Company Contribution Amounts, the
Participant’s Employer shall withhold from that portion of the Participant’s Base Salary, Bonus and/or Commissions that is not deferred, in a manner determined solely by the Employer, the Participant’s share of social security and
other required taxes on such amounts. If necessary, the Committee may reduce, in accordance with Code Section 409A, the vested portion of the Participant’s Company Contribution Account in order to comply with this Section 3.7.

  

	 	(c)	Distributions. The Participant’s Employer shall withhold from any payments made to a Participant under the Plan all federal, state and local income, employment
and other taxes required to be withheld by the Employer in connection with such payments, in amounts and in a manner to be determined in the sole discretion of the Employer. 

 ARTICLE IV 
 SCHEDULED DISTRIBUTIONS AND UNFORESEEABLE EMERGENCIES 

  

	4.1	Scheduled Distributions. In connection with each election to defer an Annual Deferral Amount, a Participant may elect to receive all or a portion of such Annual
Deferral Amount, plus amounts credited or debited on that amount pursuant to Section 3.6, in the form of a lump sum payment, valued as of the close of business on the Benefit Distribution Date designated by the Participant in accordance with
this Section 4.1 (a “Scheduled Distribution”) or, in the event such Benefit Distribution Date is not a business day, the Scheduled Distribution shall be valued as of the close of business of the next business day immediately following

 Subject to the other terms and conditions of the Plan, each Scheduled Distribution elected shall be paid out within the 60-day period commencing immediately after the Benefit Distribution Date. By way of example, if a
Scheduled Distribution is elected for Annual Deferral Amounts that are earned in the Plan Year commencing January 1, 2009, the earliest Benefit Distribution Date that may be designated by a Participant would be January 2, 2015, and the
Scheduled Distribution would be paid out within the 60-day period commencing immediately after such Benefit Distribution Date.

previously designated Benefit Distribution Date; and 

  

	 	(c)	The election must be made at least 12 months prior to the Participant’s previously designated Benefit Distribution Date for such Scheduled Distribution.

Benefit Distribution Date for such Scheduled Distribution. 
  

	4.3	Other Benefits Take Precedence Over Scheduled Distributions. In the event that an event occurs prior to any Benefit Distribution Date designated for a Scheduled

this Article IV. 

  

 - 13 - 

	4.4	Unforeseeable Emergencies. 

  

	 	(a)	Upon the written request of a Participant and the showing of an Unforeseeable Emergency prior to the occurrence of a distribution event described in Articles V through VIII, as
applicable, the Committee may, upon determining that such an emergency exists, cause an amount of such Participant’s Account Balance to be paid to him. Such amount shall not exceed the lesser of (i) the Participant’s vested Account
Balance, calculated as of the close of business on the Benefit Distribution Date for such distribution, as determined by the Committee in accordance with provisions set forth below, or (ii) the amount necessary to satisfy the Unforeseeable
Emergency (plus amounts necessary to pay federal, state, or local income taxes or penalties reasonably anticipated as a result of the distribution) after taking into account the extent to which the Unforeseeable Emergency is or may be relieved
(A) through reimbursement or compensation by insurance or otherwise, (B) by liquidation of the Participant’s assets, to the extent the liquidation of such assets would not itself cause severe financial hardship, or (C) by
cessation of deferrals under the Plan. 

 If the Committee, in its sole discretion, approves a Participant’s request for a
distribution under the Plan due to Unforeseeable Emergency, the Participant’s Benefit Distribution Date shall be the date on which such Committee approval occurs and such distribution shall be made to the Participant in a lump sum no later than
60 days after such Benefit Distribution Date; provided, however, that if the 60-day period begins in one taxable year and ends in another, the Participant shall not have a right to designate the taxable year of payment. In addition, in the event of
such approval, the Participant’s outstanding deferral elections under the Plan shall be cancelled. 
  

	 	(b)	A Participant’s deferral elections under the Plan shall also be cancelled to the extent the Committee determines that such action is required for the Participant to obtain a
hardship distribution from an Employer’s 401(k) plan pursuant to Code Section 401(k).

 - 14 - 

	 	 
provided, however, that if a Participant changes the form of distribution for one or more Annual Accounts in accordance with Section 5.2(b), the Benefit
Distribution Date for such Annual Accounts subject to such change shall be determined in accordance with Section 5.2(b). 

  

	5.2	Payment of Retirement Benefit. 

  

	 	(a)	In connection with a Participant’s election to defer an Annual Deferral Amount, the Participant shall elect the form in which his or her Annual Account for such Plan Year will
be paid. The Participant may elect to receive each Annual Account in the form of a lump sum or an Annual Installment Method of five or ten years. If a Participant does not make any election with respect to the payment of an Annual Account, then the
Participant shall be deemed to have elected to receive such Annual Account as a lump sum. 

  

	 	(b)	A Participant may change the form of payment for an Annual Account by submitting an Election Form to the Committee in accordance with the following criteria:

  

	 	(i)	The election shall not take effect until at least 12 months after the date on which the election is made;

shall not be considered to be made until the date on which the election becomes irrevocable. Such an election shall become irrevocable no later than the date that is 12 months prior to the Benefit Distribution Date that would otherwise have been
applicable to such Annual Account. Subject to the requirements of this Section 5.2(b), the Election Form most recently accepted by the Committee that has become effective for an Annual Account shall govern the form of payout of such Annual
Account. 
  

	 	(c)	The lump sum payment shall be made, or installment payments shall commence, no later than 60 days after the applicable Benefit Distribution Date. Remaining installments, if any,
shall continue in accordance with the Participant’s election for each Annual Account and shall be paid no later than 60 days after each anniversary of the Benefit Distribution Date. 

 ARTICLE VI

Participant’s Termination Benefit shall be valued as of the close of business on the Benefit Distribution Date for such benefit (or, in the event such
Benefit Distribution Date is not a business day, the Retirement Benefit shall be valued as of the close of business of the next business day immediately following such Benefit Distribution Date), which shall be (i) the first day after the end

shall receive his or her vested Account Balance in either a lump sum or annual installment payments, as elected by the Participant in accordance with Section 7.2(b) (a “Disability Benefit”). The Disability Benefit of a Participant
shall be valued as of the close of business on the Participant’s Benefit Distribution Date for such benefit (or, in the event such Benefit Distribution Date is not a business day, the Retirement Benefit shall be valued as of the close of
business of the next business day immediately following such Benefit Distribution Date), which shall be the date on which the Participant becomes Disabled. 

  

	7.2	Payment of Disability Benefit.  

  

	 	(a)	A Participant, in connection with his or her commencement of participation in the Plan, shall have elected on an Election Form to receive the Disability Benefit in a lump sum or
pursuant to an Annual Installment Method of five or ten years. If a Participant did not make any election with respect to the payment of this Disability Benefit, then such Participant shall be deemed to have elected to receive the Disability Benefit

	 	(i)	The election shall not take effect until at least 12 months after the date on which the election is made; and 

  

	 	(ii)	The election must be made at least 12 months prior to the Benefit Distribution Date that would otherwise have been applicable to the Disability Benefit. 

  

 - 16 - 

 For purposes of applying the requirements of this Section 7.2(b), a Participant’s election to
change the form of payment for the Disability Benefit shall not be considered to be made until the date on which the election becomes irrevocable. Such an election shall become irrevocable no later than the date that is 12 months prior to the
Benefit Distribution Date that would otherwise have been applicable to the Participant’s Disability Benefit. Subject to the requirements of this Section 7.2(b), the Election Form most recently accepted by the Committee that has become
effective shall govern the form of payout of the Participant’s Disability Benefit. 
  

	 	(c)	The lump sum payment shall be made, or installment payments shall commence, no later than 60 days after the Participant’s Benefit Distribution Date. Remaining
installments, if any, shall be paid no later than 60 days after the first day of each Plan Year following the Plan Year in which the Participant’s Benefit Distribution Date occurs. 

 ARTICLE VIII 
 DEATH BENEFIT

  

	8.1	Death Benefit. In the event of a Participant’s death prior to the complete distribution of his or her vested Account Balance, the Participant’s Beneficiary
shall receive the Participant’s unpaid vested Account Balance in a lump sum payment (the “Death Benefit”). The Death Benefit shall be valued as of the close of business on the Benefit Distribution Date for such benefit (or, in the
event such Benefit Distribution Date is not a business day, the Retirement Benefit shall be valued as of the close of business of the next business day immediately following such Benefit Distribution Date), which shall be the date of the
Participant’s death. 

  

	8.2	Payment of Death Benefit. Any Death Benefit shall be paid to the Participant’s Beneficiary no later than 60 days after the applicable Benefit Distribution Date.

 ARTICLE IX 
 BENEFICIARY DESIGNATION 
  

	9.1	Beneficiary. Each Participant shall have the right, at any time, to designate his or her Beneficiary (both primary as well as contingent) to receive any benefits
payable under the Plan to a beneficiary upon the death of a Participant. The Beneficiary designated under the Plan may be the same as or different from the Beneficiary designation under any other plan of an Employer in which the Participant
participates. 

  

 - 17 - 

	9.2	Beneficiary Designation. A Participant shall designate his or her Beneficiary by completing and signing the Beneficiary Designation Form, and returning it to the
Committee or its designated agent. A Participant shall have the right to change a Beneficiary by completing, signing and otherwise complying with the terms of the Beneficiary Designation Form and the Committee’s rules and procedures, as in
effect from time to time. The Committee shall be entitled to rely on the last Beneficiary Designation Form filed by the Participant and accepted by the Committee prior to his or her death. 

  

	9.3	Acknowledgment. No designation or change in designation of a Beneficiary shall be effective until received and acknowledged in writing by the Committee or its
designated agent. 

  

	9.4	No Beneficiary Designation. If a Participant fails to designate a Beneficiary as provided in Sections 9.1, 9.2 and 9.3 above, or if all designated Beneficiaries
predecease the Participant or die prior to complete distribution of the Participant’s benefits, then the Participant’s designated Beneficiary shall be deemed to be his or her surviving spouse. If the Participant has no surviving spouse,
the benefits remaining under the Plan to be paid to a Beneficiary shall be payable to the executor or personal representative of the Participant’s estate. 

  

	9.5	Doubt as to Beneficiary. If the Committee has any doubt as to the proper Beneficiary to receive payments pursuant to the Plan, the Committee shall have the right,
exercisable in its discretion, to cause the Participant’s Employer to withhold such payments until this matter is resolved to the Committee’s satisfaction. 

  

	9.6	Discharge of Obligations. The payment of benefits under the Plan to a Beneficiary shall fully and completely discharge all Employers and the Committee from all further
obligations under the Plan with respect to the Participant, and the deceased Participant’s Plan Agreement shall terminate upon such full payment of benefits. 

 ARTICLE X 
 LEAVE OF ABSENCE 
  

	10.1	Paid Leave of Absence. If a Participant is authorized by the Participant’s Employer to take a paid leave of absence from the employment of the Employer, and such
leave of absence does not constitute a Separation from Service, (a) the Participant shall continue to be considered eligible for the benefits provided under the Plan, and (b) the Annual Deferral Amount shall continue to be withheld during
such paid leave of absence in accordance with Section 3.2. 

  

	10.2	 Unpaid Leave of Absence. If a Participant is authorized by the Participant’s Employer to take an unpaid leave of absence from the employment of
the Employer for any reason, and such leave of absence does not constitute a Separation from Service, such Participant shall continue to be eligible for the benefits provided under the Plan. During the unpaid leave of absence, the Participant shall
not be allowed to make any additional deferral elections. However, if the Participant returns to employment, the Participant may elect to defer an Annual Deferral Amount for the Plan Year following his or her return to employment and 

  

 - 18 - 

	 	 
for every Plan Year thereafter while a Participant in the Plan, provided such deferral elections are otherwise allowed and an Election Form is delivered to
and accepted by the Committee for each such election in accordance with Section 3.2 above. 

 ARTICLE XI

 TERMINATION AND AMENDMENT OF PLAN 
  

	11.1	Termination of Plan. Although each Employer anticipates that it will continue the Plan for an indefinite period of time, there is no guarantee that any Employer will
continue the Plan or will not terminate the Plan at any time in the future. Accordingly, each Employer reserves the right to terminate the Plan with respect to all of its Participants. In the event of a Plan termination no new deferral elections
shall be permitted for the affected Participants and such Participants shall no longer be eligible to receive new company contributions. However, after the Plan termination the Account Balances of such Participants shall continue to be credited with
Annual Deferral Amounts attributable to a deferral election that was in effect prior to the Plan termination to the extent deemed necessary to comply with Code Section 409A, and additional amounts shall continue to credited or debited to such
Participants’ Account Balances pursuant to Section 3.6. The Measurement Funds available to Participants following the termination of the Plan shall be comparable in number and type to those Measurement Funds available to Participants in
the Plan Year preceding the Plan Year in which the Plan termination is effective. In addition, following a Plan termination, Participant Account Balances shall remain in the Plan and shall not be distributed until such amounts become eligible for
distribution in accordance with the other applicable provisions of the Plan. Notwithstanding the preceding sentence, to the extent permitted by Code Section 409A, the Employer may provide that upon termination of the Plan, all Account
Balances of the Participants shall be distributed, subject to and in accordance with any rules established by such Employer deemed necessary to comply with the applicable requirements and limitations of Code Section 409A.

  

	11.2	Amendment. Any Employer may, at any time, amend or modify the Plan in whole or in part with respect to that Employer. Notwithstanding the foregoing, (i) no
amendment or modification shall be effective to decrease the value of a Participant’s vested Account Balance in existence at the time the amendment or modification is made, and (ii) no amendment or modification of this Section 11.2 or
Section 12.2 of the Plan shall be effective.  

  

	11.3	Plan Agreement. Despite the provisions of Sections 11.1, if a Participant’s Plan Agreement contains benefits or limitations that are not in the Plan
document, the Employer may only amend or terminate such provisions with the written consent of the Participant. 

  

	11.4	Effect of Payment. The full payment of the Participant’s vested Account Balance in accordance with the applicable provisions of the Plan shall completely
discharge all obligations to a Participant and his or her designated Beneficiaries under the Plan, and such Participant’s Plan Agreement shall terminate. 

  

 - 19 - 

 ARTICLE XII 
 ADMINISTRATION 
  

	12.1	Duties of the Committee. In general, unless specifically provided otherwise in the Plan or by the Compensation Committee, the Committee shall be the Benefits
Committee, the members of which shall be appointed by the Compensation Committee. Members of the Committee may be Participants under the Plan. The Committee shall have the discretion and authority to: (a) make, amend, interpret, and enforce all
appropriate rules and regulations for the administration of the Plan; and (b) decide or resolve any and all questions, including benefit entitlement determinations and interpretations of the Plan, as may arise in connection with the Plan. Any
individual serving on the Committee who is a Participant shall not vote or act on any matter relating solely to himself or herself. When making a determination or calculation, the Committee shall be entitled to rely on information furnished by a
Participant or the Company. 

  

	12.2	Administration Upon Change In Control. Within 120 days following a Change in Control, the individuals who comprised the Committee immediately prior to the Change in
Control (whether or not such individuals are members of the Committee following the Change in Control) may, by written consent of the majority of such individuals, appoint an independent third party administrator (the “Administrator”) to
perform any or all of the Committee’s duties described in Section 12.1 above, including without limitation, the power to determine any questions arising in connection with the administration or interpretation of the Plan, and the power to
make benefit entitlement determinations. Upon and after the effective date of such appointment, (a) the Company must pay all reasonable administrative expenses and fees of the Administrator, and (b) the Administrator may only be terminated
with the written consent of the majority of Participants with an Account Balance in the Plan as of the date of such proposed termination. 

  

	12.3	Agents. In the administration of the Plan, the Committee or the Administrator, as applicable, may, from time to time, employ agents and delegate to them such
administrative duties as it sees fit (including acting through a duly appointed representative) and may from time to time consult with counsel. 

  

	12.4	Binding Effect of Decisions. The decision or action of the Committee or Administrator, as applicable, with respect to any question arising out of or in connection with
the administration, interpretation and application of the Plan and the rules and regulations promulgated hereunder shall be final and conclusive and binding upon all persons having any interest in the Plan. 

  

	12.5	Indemnity of Committee. All Employers shall indemnify and hold harmless the members of the Committee, any Employee to whom the duties of the Committee may be
delegated, and the Administrator against any and all claims, losses, damages, expenses or liabilities arising from any action or failure to act with respect to the Plan, except in the case of willful misconduct by the Committee, any of its members,
any such Employee or the Administrator. 

  

 - 20 - 

	12.6	Employer Information. To enable the Committee and/or Administrator to perform its functions, the Company and each Employer shall supply full and timely information to
the Committee and/or Administrator, as the case may be, on all matters relating to the Plan, the Trust, the Participants and their Beneficiaries, the Account Balances of the Participants, the compensation of its Participants, the date and
circumstances of the Separation from Service, Disability or death of its Participants, and such other pertinent information as the Committee or Administrator may reasonably require. 

 ARTICLE XIII 
 OTHER BENEFITS AND
AGREEMENTS 
  

	13.1	Coordination with Other Benefits. The benefits provided for or with respect to a Participant under the Plan are in addition to any other benefits available to such
Participant under any other plan, program or agreement of or with the Employer of the Participant’s Employer. The Plan shall supplement and shall not supersede, modify or amend any other such plan or program except as may otherwise be expressly
provided. 

  

	13.2	Compliance with Code Section 409A. Notwithstanding any other provision of the Plan to the contrary, any amounts, including deferrals and Employer contributions,
to be credited under the Plan with respect to a Participant shall only be credited under the Plan if such crediting will not cause the Plan to fail to comply with Code Section 409A. 

 ARTICLE XIV 
 CLAIMS PROCEDURES

  

	14.1	Maintenance of Claims Procedures. The Committee shall establish and maintain reasonable procedures governing the filing of benefit claims, notification of benefit
determinations, and appeal of benefit determinations under the Plan (collectively, the “Claims Procedures”) that comply with the requirements of ERISA Section 503 and regulations issued thereunder. Participants shall be notified of
the existence of the Claims Procedures in conjunction with enrollment in the Plan and how to obtain a copy of the Claim Procedures upon request. Compliance with the Claims Procedures is a mandatory prerequisite to any claimant’s right to
commence action under Section 14.2. 

  

	14.2	Disputes and Resolutions. In the event that a claim or dispute is not resolved to the satisfaction of the claimant through the Claims Procedure, such claimant may,
within 60 days of the final decision on review under the Claims Procedure, give written notice to the Committee to have such claim dispute settled by application for arbitration in Fairfax, Virginia in accordance with the rules then prevailing of
The American Arbitration Association pursuant to the Federal Arbitration Act. Such arbitration shall apply to all disputes and claims arising from or relating to the Plan and ERISA, and the arbitrator’s review shall be limited to a review of
the information submitted to the Plan administrator. Judgment upon any award rendered by the arbitrator may be entered in any court of U.S. competent jurisdiction. The cost of any arbitration proceeding shall be shared equally by the claimant and
the Company, unless the arbitrator finds it more equitable for the Company to bear the costs. 

  

 - 21 - 

 ARTICLE XV 
 TRUST 
  

	15.1	Establishment of the Trust. In order to provide assets from which to fulfill its obligations to the Participants and their Beneficiaries under the Plan, the Company
may establish a trust pursuant to a trust agreement with a third party, the trustee, to which each Employer may, in its discretion, contribute cash or other property, including securities issued by the Company, to provide for the benefit payments
under the Plan (the “Trust”). 

  

	15.2	Interrelationship of the Plan and the Trust. The provisions of the Plan and the Plan Agreement shall govern the rights of a Participant to receive distributions
pursuant to the Plan. The provisions of the Trust shall govern the rights of the Employers, Participants and the creditors of the Employers to the assets transferred to the Trust. Each Employer shall at all times remain liable to carry out its
obligations under the Plan. 

  

	15.3	Distributions From the Trust. Each Employer’s obligations under the Plan may be satisfied with Trust assets distributed pursuant to the terms of the Trust, and
any such distribution shall reduce the Employer’s obligations under the Plan. 

 ARTICLE XVI 
 MISCELLANEOUS 
  

	16.1	Status of Plan. The Plan is intended to be a plan that is not qualified within the meaning of Code Section 401(a) and that “is unfunded and is maintained by
an employer primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees” within the meaning of ERISA Sections 201(2), 301(a)(3) and 401(a)(1). The Plan is intended to comply with
Code Section 409A. The Plan shall be administered and interpreted to the extent possible in a manner consistent with such intent. 

  

	16.2	Unsecured General Creditor. Participants and their Beneficiaries, heirs, successors and assigns shall have no legal or equitable rights, interests or claims in any
property or assets of an Employer. For purposes of the payment of benefits under the Plan, any and all assets of an Employer shall be, and remain, the general, unpledged unrestricted assets of the Employer. The obligation of an Employer under the
Plan shall be merely that of an unfunded and unsecured promise to pay money in the future. 

  

	16.3	Employer’s Liability. The liability of an Employer for the payment of benefits shall be defined only by the Plan and the Plan Agreement, as entered into between
the Employer and a Participant. An Employer shall have no obligation to a Participant under the Plan except as expressly provided in the Plan and his or her Plan Agreement. 

  

	16.4	 Nonassignability. Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or
otherwise encumber, transfer, hypothecate, alienate or convey in advance of actual receipt, the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are expressly declared to be, unassignable and
non-transferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure, attachment, garnishment or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed by a 

  

 - 22 - 

	 	 
Participant or any other person, be transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy or insolvency
or be transferable to a spouse as a result of a property settlement or otherwise. 

  

	16.5	Not a Contract of Employment. The terms and conditions of the Plan shall not be deemed to constitute a contract of employment between any Employer and the Participant.
Such employment is hereby acknowledged to be an “at will” employment relationship that can be terminated at any time for any reason, or no reason, with or without cause, and with or without notice, unless expressly provided in a written
employment agreement. Nothing in the Plan shall be deemed to give a Participant the right to be retained in the service of any Employer, or to interfere with the right of any Employer to discipline or discharge the Participant at any time.

  

	16.6	Furnishing Information. A Participant or his or her Beneficiary will cooperate with the Committee by furnishing any and all information requested by the Committee and
take such other actions as may be requested in order to facilitate the administration of the Plan and the payments of benefits hereunder, including but not limited to taking such physical examinations as the Committee may deem necessary.

  

	16.7	Terms. Whenever any words are used herein in the masculine, they shall be construed as though they were in the feminine in all cases where they would so apply; and
whenever any words are used herein in the singular or in the plural, they shall be construed as though they were used in the plural or the singular, as the case may be, in all cases where they would so apply. 

  

	16.8	Captions. The captions of the articles, sections and paragraphs of the Plan are for convenience only and shall not control or affect the meaning or construction of any
of its provisions. 

  

	16.9	Governing Law. Subject to ERISA, the provisions of the Plan shall be construed and interpreted according to the internal laws of the State of Delaware without regard
to its conflicts of laws principles. 

  

	16.10	Notice. Any notice or filing required or permitted to be given to the Committee under the Plan shall be sufficient if in writing and hand-delivered, or sent by
registered or certified mail, to the address below: 

  

	
	Benefits Committee
	ICF International, Inc.
	Attn: Executive Vice President and General Counsel
	9300 Lee Highway
	Fairfax, Virginia 22031

 Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of
the date shown on the postmark on the receipt for registration or certification. 
 Any notice or filing required or permitted to be given to
a Participant under the Plan shall be sufficient if in writing and hand-delivered, or sent by mail, to the last known address of the Participant. 
  

 - 23 - 

	16.11	Successors. The provisions of the Plan shall bind and inure to the benefit of the Participant’s Employer and its successors and assigns and the Participant and
the Participant’s designated Beneficiaries. 

  

	16.12	Spouse’s Interest. The interest in the benefits hereunder of a spouse of a Participant who has predeceased the Participant shall automatically pass to the
Participant and shall not be transferable by such spouse in any manner, including but not limited to such spouse’s will, nor shall such interest pass under the laws of intestate succession. 

  

	16.13	Validity. In case any provision of the Plan shall be illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but
the Plan shall be construed and enforced as if such illegal or invalid provision had never been inserted herein. 

  

	16.14	Incompetency. If the Committee determines in its discretion that a benefit under the Plan is to be paid to a minor, a person declared incompetent or to a person
incapable of handling the disposition of that person’s property, the Committee may direct payment of such benefit to the guardian, legal representative or person having the care and custody of such minor, incompetent or incapable person. The
Committee may require proof of minority, incompetence, incapacity or guardianship, as it may deem appropriate prior to distribution of the benefit. Any payment of a benefit shall be a payment for the account of the Participant and the
Participant’s Beneficiary, as the case may be, and shall be a complete discharge of any liability under the Plan for such payment amount. 

  

	16.15	Domestic Relations Orders. The Committee is authorized to make any payments directed by court order in any action in which the Plan or the Committee has been named as
a party. In addition, if a court determines that a spouse or former spouse of a Participant has an interest in the Participant’s benefits under the Plan in connection with a domestic relations order (as defined in Code
Section 414(p)(1)(B)), the Committee shall have the right, notwithstanding any election made by the Participant to immediately distribute the spouse’s or former spouse’s interest in the Participant’s benefits under the Plan to
such spouse or former spouse, to the extent necessary to fulfill such domestic relations order. 

  

	16.16	Tax Treatment. Notwithstanding any other provision of the Plan to the contrary, although the Board, the Committee and the Employer shall use their commercially
reasonable efforts to avoid the imposition of taxation, penalties, and interest under Code Section 409A and other Code provisions, the tax treatment of Annual Deferrals, deferrals of Performance-Based Compensation, Company Contributions as well
as credits and earnings under the Plan shall not be, and are not, warranted or guaranteed. Neither the Board, the Committee, any Employer nor any of their designees shall be held liable for any taxes, penalties, or other amounts owed by a
Participant or Beneficiary as a result of any deferral or payment under the Plan or the administration of the Plan. 

  

	16.17	 Deduction Limitation on Benefit Payments. If the Employer reasonably anticipates that if a payment under the Plan were made as scheduled, the
deduction with respect to such payment would not be permitted solely due to the application of Code Section 162(m), the Employer may defer that payment to the extent deemed necessary to ensure deductibility; provided, however, that
(i) such deduction limitation shall be applied to all similarly situated Participants on a reasonably consistent 

  

 - 24 - 

	 	 
basis; (ii) the payment must be made by the earliest of (x) during the Employer’s first taxable year in which the Employer reasonably
anticipates, or should reasonably anticipate, that if the payment is made during such year, the deduction of such payment will not be barred by application of Code Section 162(m) or (y) during the period beginning with the date of the
Participant’s Separation from Service and ending on the later of the last day of the taxable year of the Employer in which the Participant incurs a Separation from Service of the 15th day of the third month following the Participant’s
Separation from Service; (iii) where any scheduled payment to a particular Participant in the Employer’s Taxable year is delayed because of Code Section 162(m), the delay in payment will be treated as a subsequent deferral election
unless all scheduled payments to such Participant that could be delayed are also delayed; (iv) where a payment is delayed to a date on or after the Participant’s Separation from Service, the payment will be considered a payment upon a
Separation from Service for purposes of the 6-month delay for Specified Employees; and (v) no election may be provided to a Participant with respect to the timing of payment hereunder. Any amounts deferred pursuant to the provisions of this
Section 16.17 shall continue to be credited/debited with additional amounts, even if such amount is being paid out of installments. 

 Executed at Fairfax, Virginia, on this 24th day of April, 2008.

 APPENDIX A 
 LIMITED TRANSITION RELIEF FOR DISTRIBUTION ELECTIONS MADE AVAILABLE IN ACCORDANCE WITH NOTICE 2007-86 
 The capitalized terms below shall
have the same meaning as provided in Article I of the Plan. 
 Opportunity to Make New (or Revise Existing) Distribution Elections.
Notwithstanding the required deadline for the submission of an initial distribution election under Articles IV, V and VII of the Plan, the Committee may, to the extent permitted by Notice 2007-86, provide a limited period in which Participants may
make new distribution elections, or revise existing distribution elections, with respect to amounts subject to the terms of the Plan, by submitting an Election Form on or before the deadline established by the Committee, which in no event shall be
later than December 31, 2008. Any distribution election made by a Participant, and accepted by the Committee, in accordance with this Appendix A shall not be treated as a change in either the form or timing of a Participant’s benefit
payment for purposes of Code Section 409A or the Plan. If any distribution election submitted by a Participant in accordance with this Appendix A either (a) relates to an amount that would otherwise be paid to the Participant in 2008, or
(b) would cause an amount to be paid to the Participant in 2008, such election shall not be effective.
