the applicable three (3) month period. The Facility A Commitment Fee shall be calculated on the basis of the actual number of days elapsed and a three hundred sixty (360) day year, shall be due for any three (3) month period during
which the Lenders shall have any obligation in connection with the Facility, and shall be payable in arrears, commencing on December 31, 2005, and continuing on the last Business Day of every third (3rd) calendar month thereafter for so long as this Agreement remains in effect, and on the date on which the Obligations have been paid and satisfied in

parties to this Agreement (excluding the Lender then acting in the capacity as the Agent) as of the applicable Agent Fee Due Date; provided, however, that if the number of Lender parties to this Agreement shall increase at any time (a “Lender
Joinder Date”) other than on an Agent Fee Due Date, then the Borrowers shall pay to the Agent, on the Lender Joinder Date, for the Agent’s own account and in addition to the Agent Fee paid or payable on the immediately preceding Agent Fee
Due Date, an amount equal to the product of (I) Thirteen and 89/100 Dollars ($13.89), multiplied by (II) the actual number of days that will elapse between (but including) the Lender Joinder Date and the next Agent Fee Due Date.

 ARTICLE 2 
 LETTERS OF CREDIT 
 2.1 Issuance. The Borrowers and Lenders acknowledge that from time
to time the Borrowers may request that Citizens Bank issue or amend Letter(s) of Credit. Subject to the terms and conditions of this Agreement, and any other requirements for letters of credit normally and customarily imposed by Citizens Bank,
Citizens Bank agrees to issue such requested letters of credit, provided that no Event of Default has occurred and is continuing, and no act, event or condition has occurred or exists which with notice or the passage of time, or both, would
constitute an Event of Default. If any such Letter(s) of Credit are issued by Citizens Bank, each of the Lenders shall purchase from Citizens Bank a risk participation with respect to such Letter(s) of Credit in an amount equal to such Lender’s
Percentage of such Letter(s) of Credit. Citizens Bank shall have no obligation to issue any Letter of Credit which has an expiration date beyond the Maturity Date, unless the Borrowers shall have deposited with Citizens Bank, concurrent with the
issuance of any such Letter of Credit, cash security therefor in an amount equal to the face amount of the Letter of Credit. Any request for a Letter of Credit shall be made by a Borrower submitting to the Agent an Application and Agreement for
Letter of Credit or Amendment to Letter of Credit (each being herein referred to as a “Letter of Credit Application”) on Citizens Bank’s standard form, at least three (3) Business Days prior to the date on which the issuance or
amendment of the Letter of Credit shall be required, which Letter of Credit Application shall be executed by a duly authorized officer of a Borrower, and be accompanied by such other supporting documentation and information as the Agent may from
time to time reasonably request. Each Letter of Credit Application shall be deemed to govern the terms of issuance of the subject Letter of Credit, except to the extent inconsistent with the terms of this Agreement. It is understood and agreed that
Letters of Credit shall not be issued for durations of longer than one (1) year. Any outstanding Letter of Credit may be renewed from time to time; provided that (i) at least sixty (60) days’ prior written notice thereof shall
have been given by the Borrower to the Agent and the Lenders; and (ii) no Event of Default exists under the terms and provisions of the particular Letter of Credit or this Agreement, and no act, event or condition has occurred or exists which
with notice or the passage of time, or both, would constitute an Event of Default under the terms and provisions of the particular Letter of Credit or this Agreement. 
 2.2 Amounts Advanced Pursuant to Letters of Credit. Upon the issuance of any Letter(s) of Credit (i) any amounts drawn under any Letter of Credit shall be deemed advanced ratably under the Revolver
Notes, shall bear interest and be payable in accordance with the terms of the Revolver Notes and shall be secured by the Collateral (in the same manner as all other sums advanced under the Revolver Notes); and (ii) each Lender shall purchase
from Citizens Bank such risk participations in the Letter(s) of Credit as shall be necessary to cause each Lender to share the funding obligations with respect thereto ratably in accordance with such Lender’s Percentage. It is expressly
understood and agreed that all obligations and liabilities of the Borrowers to Citizens Bank in connection with any such Letter(s) of Credit shall be deemed to be “Obligations,” and the Agent shall not be required to release its security
interest in the Collateral until (i) all Notes and all other sums due to the Lenders in connection with the Loan have been paid and satisfied in full, (ii) all Letters of Credit have been canceled or expired, and (iii) no Lender has
any further obligation or responsibility to make additional Loan advances or issue additional Letters of Credit. Furthermore, in no event whatsoever shall Citizens Bank have any obligation to issue any Letter of Credit which would cause the face
amount of all then outstanding Letters of Credit issued for the account of any or all Borrowers to exceed Five Million and No/100 Dollars ($5,000,000.00), in the aggregate, at any time. 
 2.3 Letter of Credit Fees. The Borrowers shall be jointly and severally liable for the payment of: (i) to the Agent, for the benefit
of the Lenders ratably, a quarterly- fee (the “Letter of Credit Fee”) at the annual rate equal to the Additional Libor Interest Margin corresponding to the Borrower’s Leverage Ratio reported as of the immediately preceding quarter, as
set forth on Exhibit 7 hereto, which shall be calculated (a) on the face amount of each Letter of Credit as of the date of issuance (or the anniversary or amendment date, as applicable), and (b) on the basis of the
actual number of days elapsed and a three hundred sixty (360) day year; and (ii) to the Agent, customary issuance and administrative charges (the “Letter of Credit Administration Fee”). The Letter of Credit Fee shall be due and
payable, in advance, on the date the Letter of Credit is issued, amended, extended or renewed and on the same day of every third (3rd) month thereafter during which such Letter of Credit shall remain issued or outstanding. The Letter of Credit
Administration Fee shall be due and payable simultaneously with the Agent’s issuance, amendment, extension or renewal of the particular Letter of Credit (as the case may be).

Borrower jointly and severally represents, warrants, covenants and agrees as follows: 
 5.1 Existence and Qualification. Each
Borrower is a corporation or limited liability company duly organized, validly existing and in good standing (to the extent applicable) under the laws of its jurisdiction of incorporation or organization referenced in the preamble of this Agreement,
with all corporate or limited liability company power and authority and all necessary licenses and permits to own, operate and lease its properties and carry on its business as now being conducted, and as it may in the future be conducted, except
where the failure to obtain such licenses or permits could not reasonably be expected to have a material adverse effect on such Borrower. Each Borrower has only one jurisdiction of incorporation or organization (as the case may be). Each Borrower is
duly qualified and authorized to do business and is in good standing in each jurisdiction in which the nature of its activities or the character of its properties makes qualification necessary, except where the failure to so qualify could not
reasonably be expected to have a material adverse effect on such Borrower. 
 5.2 Authority; Noncontravention. Except as set
forth in Schedule 5.2 hereto, the execution, delivery and performance of the obligations of each Borrower set forth in this Agreement, the Notes and the other Loan Documents (i) have been duly authorized by all
necessary corporate, limited liability company, stockholder or member action (as applicable); (ii) do not require the consent of any governmental body, agency or authority; (iii) will not violate or result in (and with notice or the lapse
of time will not violate or result in) the breach of any provision of any Borrower’s Articles/Certificate of Incorporation, Articles/Certificate of Organization, By-laws, Operating Agreement, Material Contracts existing as of the Restatement
Date, or any order or regulation of any governmental authority or arbitration board or tribunal; and (iv) except as permitted by the terms and provisions of this Agreement, will not result in the creation of a lien, charge or encumbrance of any
nature upon any of the properties or assets of any Borrower. When the Loan Documents are executed and delivered, they will constitute legal, valid and binding obligations of each Borrower, enforceable against each Borrower in accordance with their
respective terms, subject to applicable bankruptcy, insolvency and other similar laws affecting the rights of creditors generally. 
 5.3
Financial Position. The financial statements listed on Schedule 5.3 hereto, copies of which have been delivered to the Lenders (a) present fairly the financial condition of the Borrowers as of the date(s)
thereof and the results of the Borrowers’ operations for the periods indicated therein, (b) were prepared in accordance with GAAP, (c) with respect to all historical data, are true and accurate in all material respects, (d) with
respect to all projections, are reasonable, and (e) are not misleading in any material respect. All material liabilities, fixed or contingent, are fully shown or provided for on the referenced financial statements or the notes thereto as of the
date(s) thereof. There has been no material adverse change in the business, property or condition (financial or otherwise) of the Borrowers since the date of the most recent financial statements listed on Schedule 5.3 hereto.

  

 25 

 5.4 Payment of Taxes. Each Borrower has filed all tax returns and reports required to be

claimed to be due on or in respect of such tax returns and reports, except to the extent that the validity or amount thereof is being contested in good faith by appropriate proceedings and the non-payment thereof pending such contest will not result
in the execution of any tax lien or otherwise jeopardize the Agent’s or the Lenders’ interests in any Collateral. 
 5.5
Accuracy of Submitted Information; Omissions. As of the date furnished, all documents, certificates, information, materials and financial statements furnished or to be furnished to any Lender or the Agent pursuant to this Agreement or
otherwise in connection with the Loan (i) are true and correct in all material respects; (ii) do not contain any untrue statement of a material fact; and (iii) do not omit any material fact necessary to make the statements contained
therein or herein not misleading. No Borrower is aware of any fact which has not been disclosed to the Agent and Lenders in writing which materially adversely affects, or so far as any Borrower can now reasonably foresee, could materially adversely
affect, the properties, business, profit or condition (financial or otherwise) of any Borrower or the ability of any Borrower to perform its obligations set forth in this Agreement or in any other Loan Document. 
 5.6 Government Contracts/Government Subcontracts. Except for the matters set forth on Schedule 5.6(a) hereto, since
December 31, 2000, and with respect to Caliber Entities, December 31, 2001, no notice of suspension, debarment, cure notice, show cause notice or notice of termination for default has been issued by the Government to any Borrower, and no
Borrower is a party to any pending, or to any Borrower’s knowledge threatened, suspension, debarment, termination for default or show cause requirement by the Government or other adverse Government action or proceeding in connection with any
Government Contract; it being understood and agreed that, for purposes hereof, normal and customary reviews and audits conducted by the Government in the ordinary course of business shall not be deemed adverse Government action(s) or proceeding(s).

more, and (ii) a remaining term of twelve (12) months or longer are listed on Schedule 5.6(b) hereto. 
 5.7
No Defaults or Liabilities. No Borrower is in default of any obligation, covenant or condition contained in any Material Contract which materially adversely affects, or could reasonably be expected to have a material adverse effect on,
the properties, business, profit or condition (financial or otherwise) of such Borrower or the ability of such Borrower to perform its obligations set forth in this Agreement or in any other Loan Document. Additionally, except for the matters
disclosed on Schedule 5.9 hereto, there is no litigation, legal or administrative proceeding or investigation pending against any Borrower, and no litigation, legal or administrative proceeding or investigation has been
threatened against any Borrower, which has not been disclosed to the Agent and the Lenders in writing and which involves amounts in excess of Five Hundred Thousand and No/100 Dollars ($500,000.00) or which could prejudice, in any material respect,
the Agent’s or any Lender’s rights or remedies under any Loan Document, or the priority, perfection or enforceability of the Agent’s security interest in or lien on any Collateral. 
 5.8 No Violations of Law. No Borrower is in violation of any Applicable Laws in any material respect; no Borrower has failed to obtain any
license, permit, franchise or other governmental authorization necessary to the ownership of its properties or to the conduct of its business, and each Borrower has conducted its business and operations in compliance with all Applicable Laws, except
for such non-compliance which could not reasonably be expected to have a material adverse effect on such Borrower. 
 5.9 Litigation
and Proceedings. Except for the matters set forth on Schedule 5.9 attached hereto, as of the Restatement Date, no action, suit or proceeding against or affecting any Borrower is presently pending, or to the knowledge of
any Borrower, threatened, in any court, before any governmental agency or department, or before any arbitration board or tribunal, which involves the possibility of any judgment or liability in excess of Five Hundred Thousand and No/100 Dollars
($500,000.00) and is not fully covered by insurance. No Borrower is in default with respect to any order, writ, injunction or decree of any court, governmental authority or arbitration board or tribunal.

 5.10 Security Interest in the Collateral. Each Borrower is the sole legal and beneficial
owner of the Collateral owned or purported to be owned by it, free and clear of all liens, claims and encumbrances of any nature, except for the Permitted Liens and other liens expressly permitted by the terms and provisions of this Agreement.
Except as expressly set forth in this Agreement or unless requirements of any applicable foreign law(s) dictate an alternative or additional method of creating valid and enforceable security interests in the Collateral (or, as the case may be under
any applicable foreign law, such foreign jurisdiction’s equivalent of a valid and enforceable security interest in and to such Collateral), the security interests and liens granted by the Borrowers to the Agent pursuant to this Agreement
constitute valid and enforceable security interests in and liens on each item of the Collateral of the type or nature which may be made subject to a security interest under the UCC, subject to no other liens other than Permitted Liens. Upon
execution of this Agreement, and subject to (i) the filing of UCC-1 financing statements containing a description of the Collateral and naming the Borrowers as debtors in the appropriate jurisdictions as determined by applicable law, and/or
(ii) the requirements of any applicable foreign law(s) which dictate an alternative or additional method of perfecting the security interest (or, as the case may be under any applicable foreign law, such foreign jurisdiction’s equivalent
of a perfected lien on and security interest) in the Collateral pursuant to this Agreement, the security interests and liens granted by the Borrowers to the Agent, for the benefit of the Lenders ratably, pursuant to this Agreement
(a) constitute perfected security interests in all Collateral of the type or nature in which a security interest may be perfected by filing, recording or registering a financing statement in the United States pursuant to the UCC, (b) shall
be superior to and prior to any other lien on any of such Collateral (but excluding Collateral consisting of capital stock, membership interests or ownership interests in any Foreign Borrower), other than Permitted Liens, and no further recordings
or filings are or will be required in connection with the creation, perfection or enforcement of such security interests and liens, other the filing of continuation statements in accordance with applicable law, and (c) in the case of Collateral

delivery thereof to the Government, such Prime Contractor or any person or entity acting for or on behalf of the Government or such Prime Contractor. If any letter, notice, subpoena, court order, pleading or other document required to be delivered
to the Agent, the Agent’s counsel and each Lender pursuant to this Section 6.10 contains any information deemed “classified” by the Government and/or the dissemination of any such information to the Agent, the Agent’s
counsel and each Lender would result in the Borrowers violating any Applicable Law, then the Borrowers shall deliver to the Agent, the Agent’s counsel and each Lender a summary of such letter, notice, subpoena, court order, pleading or other
document containing a summary thereof, but including as much (but no more than) detail as can be included therein without violating any Applicable Law.

however, that (i) no Borrower’s failure to execute and deliver any Government Contract Assignment shall constitute a default, breach or violation of the Borrowers’ obligation(s) set forth in this Section 6.11, unless the Agent
shall have made written demand upon the Borrowers to fully and faithfully comply with its obligation(s) with respect to Government Contract Assignments set forth in this Section 6.11 above, and such demand shall have been issued by the Agent

(b) has a remaining term of less than twelve (12) months (with no option to extend), or (c) has an Approved International Organization as the other party thereto. The Borrowers acknowledge that the Agent and the Lenders will be
irreparably harmed if any Borrower fails or refuses to execute and deliver any Government Contract Assignment after the Agent’s demand therefor, as and when required pursuant to this Section 6.11, and that the Agent and the Lenders have no
adequate remedy at law. In such event, the Borrowers agree that the Agent shall be entitled, in addition to all other rights and remedies available to the Agent and/or the Lenders, to injunctive or other equitable relief to compel the

 (a) Fixed Charge Coverage Ratio. The Borrowers will maintain on a consolidated basis for each quarter, a Fixed Charge Coverage Ratio of not less
than 1.10 to 1.00. For purposes of the foregoing, “Fixed Charge Coverage Ratio” shall mean, for each measurement period, the sum of the Borrowers’ EBITDA, plus real property rent expense and operating lease expense, divided
by the sum of the Borrowers’ real property rent expense and operating lease expense, plus interest expense, plus cash taxes paid, plus required principal payments on debt and capital lease payments; provided, however,
that (i) Principal payments made under Facility C, and (ii) the Primary Operating Company’s assumption of Caliber’s tax liability in an amount not to exceed Four Million and No/100 Dollars ($4,000,000.00) will be excluded from
the calculation of the Fixed Charge Coverage Ratio. The Fixed Charge Coverage Ratio shall be measured on the last day of each fiscal quarter throughout the term of the Loan.

of the foregoing, “Leverage Ratio” shall mean, for each measurement period, the ratio of the Borrower’s Total Debt to EBITDA. The Leverage Ratio shall be measured on the last day of each fiscal quarter throughout the term of the Loan.

 (c) Capital Expenditures. The Borrowers shall not, on an aggregate and consolidated basis, make or incur any capital expenditures,
during any Fiscal Year, in excess of an amount equal to one and one-half percent (1.50%) of the Borrowers’ gross annual revenues for the immediately preceding twelve (12) month period. 
 (d) Continued Profitability. The Borrowers shall not, on a consolidated basis, sustain or incur negative Consolidated Net Operating Income for
any fiscal quarter throughout the term of the Loan. 
 (e) Maximum Total Senior Debt. The Borrowers shall not, at any time, suffer or
permit Total Senior Debt to exceed the aggregate amount of all of the Borrowers’ Receivables (including all billed and unbilled Receivables). For purposes hereof, “Total Senior Debt” shall mean Total Debt, less the sum of (i) the
aggregate unpaid amount of principal, accrued interest and other amounts payable in respect of Facility C, plus (ii) any and all other indebtedness expressly subordinated to the Loan in payment, priority, collection and all other
respects pursuant to one or more written subordination agreements acceptable to the Agent in all respects.

 Except as otherwise expressly provided above, the financial covenants referenced above shall be
calculated and tested on a rolling four (4) quarter basis, and shall include the results of any entity acquired pursuant to a Permitted Acquisition and consolidated into the Borrowers’ financial statements within the twelve (12) month
period immediately preceding the applicable covenant calculation date; provided, however, that for the quarters ending December 31, 2005, March 31, 2006 and June 30, 2006, the financial covenants referenced above shall be calculated
and tested on an annualized basis, beginning with the results for the quarter ending December 31, 2005. Unless otherwise defined, all financial terms used in this Section 6.15 shall have the meanings attributed to such terms in accordance
with GAAP.

the Agent, prior to any such move or relocation, a landlord lien waiver, in form and substance reasonably satisfactory to the Agent, pursuant to which each landlord shall subordinate any statutory, contractual or other lien the landlord may have in
any of the Collateral to the lien, operation and effect of the lien granted to the Agent pursuant to this Agreement and the other Loan Documents. Notwithstanding the foregoing, on or prior to November 22, 2005, all books and records of Caliber
shall be moved to one of the Borrowers’ current primary business location(s) listed on Schedule 5.11 to this Agreement. 
 6.18
Substitute Notes. Upon request of the Agent, each Borrower shall execute and deliver to the Agent substitute promissory notes, in form and substance satisfactory to the Agent in all respects, payable to the order of such person or
entity as may be designated by the Agent; it being understood and agreed, however, that the aggregate principal amount of all outstanding promissory notes shall not exceed the Commitment Amount (plus the Swing Line Commitment Amount) as of the date
such substitute note(s) are issued. 
 6.19 Interest Rate Contracts. The Borrowers shall have in effect within thirty
(30) days of Closing at all times until the third (3rd) anniversary of the Restatement Date, one or more interest rate protection agreements (“Interest Rate Contracts”), in form and substance reasonably satisfactory to the Agent
in all respects (but in no event on terms that are other than commercially reasonable) covering a minimum amount of Fifteen Million and No/100 Dollars ($15,000,000.00) of the Borrowers’ Obligations. The Borrowers may have in effect, from time
to time, Interest Rate Contracts reasonably satisfactory to the Agent. Any such Interest Rate Contract must be purchased from the Agent. The Borrowers’ obligations under any Interest Rate Contract purchased from the Agent shall be secured by
the Collateral on a pari passu basis. The Borrowers shall determine to their own satisfaction whether each such Interest Rate Contract is sufficient to meet the Borrowers’ needs for interest rate protection, and neither the Agent nor any Lender
shall have any obligation or liability with respect thereto, nor any obligation to propose, quote or enter into any Interest Rate Contract, unless such Interest Rate Contract shall be on terms and conditions satisfactory to the Agent in all
respects.

to the Collateral Account within two (2) Business Days of the receipt thereof and in precisely the form received. Pending such deposit, the Borrowers will not commingle any such items of payment with any of their other funds or property, but

 The Borrowers hereby covenant and agree that the Collateral Account, the Transitional Deposit Account and the Permitted Foreign Bank Accounts shall secure the Obligations and hereby grants, assigns and transfers to or at the direction of
the Agent, for the benefit of the Lenders ratably, a continuing security interest in all of the Borrowers’ right, title and interest in and to the Collateral Account, the Transitional Deposit Account and the Permitted Foreign Bank Accounts,
whenever created or established. Subject to the terms of this Agreement or any other Loan Document, the Agent may apply funds in the Collateral Account, the Transitional Deposit Account and/or the Permitted Foreign Bank Accounts to any of the

origin of the deposits in the account, the beneficial ownership of the funds therein or whether such Obligations are owed jointly with another or severally; the order and method of such application to be in the sole discretion of the Agent. The
Agent’s right to deduct sums due under the Loan Documents from the Borrowers’ account(s) shall not relieve the Borrowers from their obligation to make all payments required by the Loan Documents as and when required by the Loan Documents,

 (p) if the Required Lenders believe that a material adverse change shall have occurred in the business,
assets, properties, condition (financial or otherwise) of the Borrowers, in the aggregate. 
 9.2 Remedies. Without limiting
any right or remedy of the Agent and/or the Lenders set forth in this Agreement, upon the occurrence of any Event of Default, the Agent, acting on behalf of the Lenders, may exercise any or all of the following remedies: 
 (a) Withhold disbursement of all or any part of the Loan proceeds; 
 (b) Terminate the Lenders’ obligation to make further disbursements of the Loan proceeds; 
 (c)
Declare all principal, interest and other sums owing on the Obligations to be immediately due and payable without demand, protest, notice of protest, notice of default, presentment for payment or further notice of any kind; 
 (d) Without notice, redirect any and all of the Borrowers’ deposits to the Collateral Account or any other account under the Agent’s exclusive
control; 
 (e) Without notice, offset and apply against all or any part of the Obligations then owing by any Borrower to any Lender, any
and all money, credits, stocks, bonds or other securities or property of any Borrower of any kind or nature whatsoever on deposit with, held by or in the possession of any Lender in any capacity whatsoever, including, without limitation, any
deposits with any Lender or any of its Affiliates, to the credit of or for the account of any Borrower. The Agent and Lenders are authorized at any time to charge the Obligations against any Borrower’s account(s), without regard to the origin
of deposits to the account or beneficial ownership of the funds. Any and all amounts obtained by the Agent or any Lender pursuant to this subsection (e) shall be shared by all of the Lenders ratably, in accordance with each Lender’s
Percentage; it being expressly acknowledged and agreed that each Lender, as well as the Agent, shall be entitled to exercise the rights of set-off provided in this subsection (e) of this Section 9.2; 
 (f) Exercise all rights, powers and remedies of a secured party under the UCC and/or any other applicable law(s), including, without limitation, the
right to (i) require any Borrower to assemble the Collateral (to the extent that it is movable) and make it available to the Agent at a place to be designated by the Agent, and (ii) enter upon any Borrower’s premises, peaceably by the
Agent’s own means or with legal process, and take possession of, render unusable or dispose of the Collateral on such premises; each Borrower hereby agreeing not to resist or interfere with any such action. The Agent agrees to give the
Borrowers written notice of the time and place of any public sale of the Collateral or any part thereof, and the time after which any private sale or any other intended disposition of the Collateral is to be made, and such notice will be mailed,
postage prepaid, to the principal place of business of the Borrowers, at least ten (10) days before the time of any such sale or disposition. Each Borrower hereby authorizes and appoints the Agent and its successors and assigns to (x) sell
the Collateral, and (y) declare that each Borrower assents to the passage of a decree by a court of proper jurisdiction for the sale of the Collateral. Any such sale pursuant to (x) or (y) above is to be made in accordance with the
applicable provisions of the laws and rules of procedure of the Commonwealth of Virginia or other applicable law; and/or 
 (g) Proceed to
enforce such other and additional rights and remedies as the Agent and/or Lenders may have hereunder and/or under any of the other Loan Documents, or as may be provided by applicable law. 
 It is expressly understood and agreed that the Lenders and/or the Agent may exercise their respective rights under this Agreement or under any other Loan
Document without exercising the rights or affecting the security afforded by any other Loan Document, and it is further understood and agreed that the Agent may (at the direction of the Required Lenders) proceed against all or any portion of the
Collateral in such order and at such times as the Agent, in its sole discretion, sees fit; and each Borrower hereby expressly waives, to the extent permitted by law, all benefit of valuation, appraisement, marshaling of assets and all exemptions
under the laws of the Commonwealth of Virginia and/or any other state, district or territory of the United States. Notwithstanding the 
  

 44 

 foregoing delegation of authority by the Lenders to the Agent, it is agreed that at any time there are two (2) or
fewer Lender parties to this Agreement, any Lender may request the Agent to commence enforcement action against the Borrowers and/or Collateral upon an Event of Default. In this event, if the Agent fails or refuses to take enforcement action upon
the request of a Lender, such Lender may itself commence appropriate enforcement action. Furthermore, if any Borrower shall default in the performance when due of any of the provisions of this Agreement, the Agent, without notice to or demand upon
the Borrowers (and without any grace or cure period) and without waiving or releasing any of the Obligations or any default hereunder, under the Notes or under any other Loan Document, may (but shall be under no obligation to) perform the same for
each Borrower’s account, and any monies expended in so doing shall be chargeable to the Borrowers with interest, at the highest rate of interest payable under Notes, plus two percent (2%) per annum, and added to the indebtedness secured by
the Collateral. 
 All sums paid or advanced by the Agent (or any Lender to the extent incurred pursuant to this Agreement) in connection
with the foregoing or otherwise in connection with the Loan, and all court costs and expenses of collection, including without limitation, reasonable attorneys’ fees and expenses (and fees and expenses resulting from the taking, holding or
disposition of the Collateral) incurred in connection therewith shall be paid by the Borrowers upon demand and shall become a part of the Obligations secured by the Collateral. The Borrowers agree to bear the expense of each lien search, property
and judgment report or other form of Collateral ownership investigation as the Agent, in its discretion, shall deem necessary or desirable to assure or further assure to the Lenders and/or the Agent their respective interests in the Collateral.

 ARTICLE 10 
 THE
AGENT; AGENCY 
 10.1 Appointment. Each Lender hereby affirms its irrevocable appointment of Citizens Bank to act as the
Agent for each such Lender pursuant to the provisions of this Agreement and the other Loan Documents, and affirms its irrevocable authorization given to the Agent to take such action, and exercise such powers and perform such duties as are expressly
delegated to or required of the Agent by the terms hereof or thereof, or are reasonably incidental thereto, including without limitation, executing documents on behalf of the Lenders, as Agent. Citizens Bank affirms its agreement to act as the Agent
on behalf of the Lenders on the terms and conditions set forth in this Agreement and the other Loan Documents, subject to its right to resign as provided in Section 10.10. Each Lender agrees that the rights and remedies granted to the Agent
under this Agreement and the other Loan Documents shall be exercised exclusively by the Agent, and that no Lender shall have the right individually to exercise any such right or remedy, except to the extent expressly provided herein or therein.

 10.2 General Nature of Agent’s Duties. Notwithstanding anything to the contrary elsewhere in this Agreement or any
other Loan Document: 
 (a) The Agent shall have no duties or responsibilities other than those expressly set forth in this Agreement and the
other Loan Documents, and no implied duties or responsibilities on the part of the Agent shall be read into this Agreement or any other Loan Document or shall otherwise exist. 
 (b) The duties and responsibilities of the Agent under this Agreement and the other Loan Documents shall be mechanical and administrative in nature, and
the Agent shall not have a fiduciary relationship in respect of any Lender. 
 (c) The Agent is and shall be solely the agent of the
Lenders. The Agent does not assume, and shall not at any time be deemed to have, any relationship of agency or trust with or for, or any other duty or responsibility to, any Borrower or any other person (except only for its relationship as agent
for, its express duties and responsibilities as agent for, and its express duties and responsibilities to, the Lenders as provided in this Agreement and the other Loan Documents). 
 (d) The Agent shall not have any obligation to take any action hereunder or under any other Loan Document if the Agent believes in good faith that
taking such action may (i) conflict with any Applicable Laws, or any provision of this Agreement or any other Loan Document, (ii) may require the Agent to qualify to do business in any jurisdiction where it is not then so qualified, or
(iii) result in any liability of the Agent or any Lender not fully covered by insurance. 
  

 45 

 10.3 Exercise of Powers. 
 (a) The Agent shall have the authority to take any action of the type specified in this Agreement or any other Loan Document as being within the
Agent’s rights, powers or discretion, as it determines in its sole discretion, except as provided in subsection (b) below, and except as provided herein or in any other Loan Document, when such action expressly requires the direction or
consent of (i) the Required Lenders; or (ii) all of the Lenders, in either of which circumstances the Agent shall not take such action absent such direction or consent. Any action or inaction pursuant to such direction or consent shall be
binding on all of the Lenders. 
 (b) The Agent shall not in any material respect amend, modify, grant consents or waive any term or
provision of this Agreement or any other Loan Document without the consent or approval of the Required Lenders, or declare an Event of Default, provide formal written notice of default to any Borrower or exercise any rights or remedies against any
Borrower without the prior consent of the Required Lenders. Each Lender agrees that its decision to consent to or reject any request by the Agent for permission to declare an Event of Default, provide formal notice thereof to any Borrower and/or
exercise any rights or remedies arising by virtue of such default, shall be made as soon as reasonably practicable after the Lender has received all relevant information with respect to such request (to the extent such information shall be readily
available), but in all events within five (5) Business Days of the receipt of such information; it being understood and agreed that, unless otherwise provided herein, the Agent shall exercise any and all rights and responsibilities on behalf of
the Lenders in connection with an Event of Default. Additionally, only with the consent or approval of all of the Lenders, the Agent may (a) extend the final maturity of the Loan or any Note, reduce the interest rate payable on or extend the
time of payment for any installment of principal, interest or fees payable in connection with the Loan, or issue Letters of Credit (i) having an expiration date beyond the Maturity Date, except as otherwise expressly provided in this Agreement,
or (ii) causing the aggregate outstanding amount of all such Letters of Credit issued to exceed Five Million and No/100 Dollars ($5,000,000); (b) change the Percentage of the Commitment Amount of any Lender, (c) release all or a
substantial portion of the Collateral, except in accordance with the provisions of any applicable Loan Document, (d) amend the definition of the Required Lenders or expand the definitions of Eligible Billed Government Accounts Receivable,

provisions set forth in this Section 10.3, (g) change the manner of application by the Agent of payments made under the Loan Documents, or (h) change the method of calculation used in connection with the computation of interest,
commissions or fees. Each Lender agrees that its decision to approve or reject any request for an amendment or waiver with respect to this Agreement shall be made as soon as reasonably practicable after the Lender has received all relevant
information with respect to such request. 
 10.4 General Exculpatory Provisions. Notwithstanding anything to the contrary
elsewhere in this Agreement or any other Loan Document: 
 (a) The Agent, in its capacity as Agent (but not as a Lender), shall not be liable
for any action taken or omitted to be taken by it in a manner consistent with the terms of this Agreement or any other Loan Document, unless caused by its own gross negligence or willful misconduct. 
 (b) The Agent shall not be responsible for (i) the execution, delivery, effectiveness, enforceability, genuineness, validity or adequacy of this
Agreement or any other Loan Document, (ii) any recital, representation, warranty, document, certificate, report or statement in this Agreement or any other Loan Document, (iii) any failure of any Borrower or any Lender to perform any of
their respective obligations under this Agreement or any other Loan Document, (iv) the existence, validity, enforceability, perfection, recordation, priority, adequacy or value, now or hereafter, of any lien or encumbrance or other direct or
indirect security afforded or purported to be afforded by any of the Loan Documents, or otherwise from time to time, or (v) caring for, protecting, insuring or paying any taxes, charges or assessments with respect to any Collateral. 

 

 46 

 (c) The Agent shall have no obligation to ascertain, inquire or give any notice relating to (i) the
performance or observance of any of the terms or conditions of this Agreement or any other Loan Document on the part of any Borrower, (ii) the business, operations, condition (financial or otherwise) or prospects of any Borrower, or
(iii) except as otherwise expressly set forth in this Agreement, the occurrence or existence of any Event of Default. 
 (d) The Agent
shall have no obligation, either initially or on a continuing basis, to provide any Lender with any notices, reports or information of any nature, whether in its possession presently or hereafter, except for such notices, reports and other
information expressly required by this Agreement or any other Loan Document to be furnished by the Agent to such Lender. 
 10.5
Administration by the Agent. 
 (a) The Agent may rely upon any notice or other communication of any nature (written or oral,
including telephone conversations, whether or not such notice or other communication is made in a manner permitted or required by this Agreement or any other Loan Document) purportedly made by or on behalf of the proper party or parties, and the
Agent shall not have any duty to verify the identity or authority of any person giving such notice or other communication. 
 (b) The Agent
may consult with legal counsel (including in-house counsel for the Agent), independent public accountants and any other experts selected by the Agent from time to time, and the Agent shall not be liable for any action reasonably taken or omitted to
be taken in good faith by it in accordance with the advice of such counsel, accountants or experts. 
 (c) The Agent may conclusively rely
upon the truth of the statements and the correctness of the opinions expressed in any certificates or opinions furnished to the Agent in accordance with the requirements of this Agreement or any other Loan Document. Whenever the Agent shall deem it
necessary or desirable that a matter be proved or established with respect to any Borrower or any Lender, such matter may be established by a certificate of such Borrower or such Lender, as the case may be, and the Agent may conclusively rely upon
such certificate. 
 (d) The Agent may fail or refuse to take any action unless it shall be indemnified to its satisfaction from time to
time against any and all amounts, liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of every kind and nature which may be imposed on, incurred by or asserted against the Agent by
reason of taking or continuing to take any such action; provided that no Lender shall be obligated to indemnify the Agent for any portion of such amounts, liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses and disbursements resulting solely from the gross negligence or willful misconduct of the Agent, as finally determined by a court of competent jurisdiction. 
 (e) The Agent may perform any of its duties under this Agreement or any other Loan Document by or through agents or attorneys-in-fact. The Agent shall not be responsible for the negligence or misconduct of any agents
or attorneys-in-fact selected by it with reasonable care. 
 (f) The Agent shall not be deemed to have any knowledge or notice of the
occurrence of any Event of Default (other than a default in the payment of regularly scheduled principal or interest), unless the Agent has received from a Lender or a Borrower a written notice describing the Event of Default. If the Agent receives
such a notice, the Agent shall give prompt notice thereof to each Lender, unless such notice shall have been addressed and/or issued to all of the Lenders. 
 (g) The Agent shall provide three (3) Business Days prior notice to the Lenders of any field audit scheduled to be performed by the Agent pursuant to Section 1.6 of this Agreement. The Lenders shall be
entitled to (i) receive copies of field audits performed by the Agent, and (ii) accompany the Agent to any field audit, provided that the Agent may, in its discretion, limit the number of Lender representatives attending any such field
audit. 
  

 47 

 10.6 Lenders Not Relying on the Agent or Other Lenders. Each Lender acknowledges as
follows: 
 (a) Neither the Agent nor any other Lender has made any representations or warranties to it, and no act taken hereafter by the
Agent or any other Lender shall be deemed to constitute any representation or warranty by the Agent or such other Lender to it; 
 (b) It
has, independently and without reliance upon the Agent or any other Lender, and based upon such documents and information as it has deemed appropriate, made its own credit and legal analysis and decision to enter into this Agreement and the other
Loan Documents; and 
 (c) It will, independently and without reliance upon the Agent or any other Lender, and based upon such documents and
information as it shall deem appropriate at the time, make its own decisions to take or not take action under or in connection with this Agreement and the other Loan Documents. 
 10.7 Indemnification. Each Lender agrees to reimburse and indemnify the Agent and the Agent’s directors, officers, employees and
agents (to the extent not reimbursed by the Borrowers, and without limitation of the obligation of the Borrowers to do so), ratably in accordance with each Lender’s Percentage, from and against any and all amounts, losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs and disbursements of every kind or nature (including the reasonable fees and disbursements of counsel for the Agent or such other person in connection with any
investigative, administrative or judicial proceeding commenced or threatened, whether or not the Agent or such other person shall be designated a party thereto) that may at any time be imposed on, incurred by or asserted against the Agent or such
other person as a result of this Agreement, any other Loan Document, any transaction from time to time contemplated hereby or thereby, or any transaction financed in whole or in part or directly or indirectly with the proceeds of the Loan;
provided that no Lender shall be obligated to indemnify the Agent or such other person for any portion of such amounts, losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements
resulting solely from the gross negligence or willful misconduct of the person seeking indemnity, as finally determined by a court of competent jurisdiction. 
 10.8 Agent in its Individual Capacity; Agent’s Commitment. 
 (a) With respect to its
commitment and the Obligations owing to it, Citizens Bank shall have the same rights and powers under this Agreement and each other Loan Document as any other Lender, and may exercise the same as though it was not the Agent. The terms
“Lender,” “holders of Notes” and like terms shall include Citizens Bank in its individual capacity. Citizens Bank and its Affiliates may, without liability to account for, make loans to, accept deposits from, acquire debt or
equity interests in, act as trustee under indentures of and engage in any other business with any Borrower and any Affiliate of any Borrower, as though Citizens Bank was not the Agent hereunder. 
 (b) The Agent hereby agrees that it shall at all times maintain, at a minimum, the lesser of (the “Agent’s Commitment”): 
 (i) a Ten Million and No/100 Dollar ($10,000,000.00) interest in the aggregate Commitment Amount; or 
 (ii) a Percentage of the Commitment Amount that is at least equal to twenty-five percent (25%). 
 In the event the Agent fails to maintain the Agent’s Commitment, the Agent agrees to resign as the Agent hereunder, if requested by the Borrowers and/or the
Lenders, pursuant to Section 10.10 of this Agreement; it being expressly acknowledged and agreed that the Borrowers shall be third party beneficiaries of the Agent’s Commitment requirement set forth in this Section 10.8(b).

  

 48 

 10.9 Holders of Notes. Without limiting the requirements of Section 12.11 of this
Agreement, the Agent may deem and treat any Lender which is the payee of a Note as the owner and holder of such Note for all purposes hereof unless and until written notice evidencing such transfer shall have been filed with the Agent. Any
authority, direction or consent of any person who at the time of giving such authority, direction or consent was a Lender shall be conclusive and binding on each present and subsequent holder, transferee or assignee of any Note or Notes payable to
such Lender or issued in exchange therefor. 
 10.10 Successor Agent. The Agent may resign at any time by giving thirty
(30) days prior written notice thereof to the Lenders and Borrowers, subject to appointment of a successor Agent (and such appointees acceptance of appointment) as below provided in this Section 10.10. Additionally, the Agent may be
removed for cause by all of the Lenders (other than the Agent, if the Agent is then a Lender), or in the absence of an Event of Default, the Borrowers may request the Agent’s resignation pursuant to Section 10.8(b) hereof, if removal or
resignation, as applicable, is requested in writing (which wording must specifically identify the “cause” for removal), and ten (10) days’ prior written notice of removal or resignation is provided to the Agent and Borrowers (or
Lenders, if applicable). Upon any such resignation or removal, the Agent shall, on behalf of the Lenders, immediately appoint, as its successor, another Lender; provided that such Lender is a commercial bank or trust company organized under the laws
of the United States of America or any State thereof and has a combined capital and surplus of at least Five Hundred Million and No/100 Dollars ($500,000,000.00). In such event, the Agent’s resignation or removal shall not be effective until
the successor Agent shall have accepted its appointment. Upon the acceptance by a successor Agent of its appointment as the Agent hereunder, such successor Agent shall thereupon succeed to and become vested with all of the properties, rights,
powers, privileges and duties of the former Agent, without further act, deed or conveyance. Upon the effective date of resignation or removal of the retiring Agent and payment of all amounts then due and payable by the Agent to the Lenders pursuant
to this Agreement, such Agent shall be discharged from its duties under this Agreement and the other Loan Documents. If for any reason, at any time, there is no Agent hereunder, then during such period, the Required Lenders shall have the right to
exercise the Agent’s rights and perform its duties hereunder, except that (i) all notices or other communications required or permitted to be given to the Agent shall be given to each Lender, and (ii) all payments to be made to the
Agent shall be made directly to the Borrowers or the Lender for whose account such payment is made. 
 10.11 Additional Agents.
If the Agent shall from time to time deem it necessary or advisable to engage other agents for its own protection in the performance of its duties hereunder or in the interests of the Lenders, then the Agent and Borrowers shall execute and deliver a
supplemental agreement and all other instruments and agreements necessary or advisable, in the opinion of the Agent, to constitute another commercial bank or trust company, or one or more other persons approved by the Agent, to act as co-Agent or a
separate agent with respect to any part of the Collateral, with such powers as may be provided in such supplemental agreement, and with the power to vest in such bank, trust company or other person (as such co-Agent or separate agent, as the case
may be), any properties, rights, powers, privileges and duties of the Agent under this Agreement or any other Loan Document. 
 10.12
Calculations. The Agent shall not be liable for any calculation, apportionment or distribution of payments made by it in good faith. If such calculation, apportionment or distribution is subsequently determined to have been made in
error, the sole recourse of any Lender to whom payment was due but not made shall be to recover from the Lenders any payment in excess of the amount to which they are determined to be entitled, with interest thereon at the Federal Funds Rate, or, if
the amount due was not paid by any Borrower, to recover such amount from such Borrower (subject to the terms and provisions of this Agreement), with interest thereon at the rate provided in the applicable Note. 
 10.13 Funding by the Agent. 
 (a) Except as otherwise provided in this Agreement, the Agent alone shall be entitled to make all advances in connection with the Loan and shall receive all payments and other receipts relating to the Loan; it being understood, however,
that the Agent has reserved the right not to advance any amounts to the Borrowers which the Agent has not received from the Lenders. The Agent will notify each Lender of the date and amount of any requested advance, and if such notification is
received by 1:00 p.m. Washington, D.C. time on any 
  

 49 

 given Business Day, the Lenders shall provide the required funds to the Agent no later than the close of business on such
Business Day. Once per week, or within such shorter time frame as may be requested by the Agent or the Swing Line Lender, the Agent and each Lender shall pay to each other such amounts (the “Equalization Payments”) as may be necessary to
cause each Lender to own its applicable Percentage of the Loan and otherwise implement the terms and provisions of this Agreement; it being understood that each Lender shall be entitled to receive interest on amounts advanced by it only from the
date of such Lender’s advance of funds. The obligation of the Agent and each Lender to make Equalization Payments shall not be affected by a bankruptcy filing by any Borrower, the occurrence of any Event of Default or any other act, occurrence
or event whatsoever, whether the same occurs, before, on or after the date on which an Equalization Payment is required to be made. All Equalization Payments shall be made by 5:00 p.m. Washington, D.C. time on the date such payment is required,
provided that notice of such Equalization Payment shall have been given to the party obligated to make such payment by 1:00 p.m. Washington, D.C. time; otherwise such Equalization Payment shall be made on the next Business Day. 
 (b) Unless the Agent shall have been notified in writing by any Lender no later than the close of business on the Business Day before the Business Day
on which an advance requested by the Borrowers is to be made, that such Lender will not make its ratable share of such advance, the Agent may assume that such Lender will make its ratable share of the advance, and in reliance upon such assumption
the Agent may (but in no circumstances shall be required to) make available to the Borrowers a corresponding amount. If and to the extent that any Lender fails to make such payment to the Agent when required, such Lender shall pay such amount on
demand (or, if such Lender fails to pay such amount on demand, the Borrowers shall arrange for the repayment of such amount to the Agent), together with interest for the Agent’s own account for each day from and including the date of the
Agent’s payment, to and including the date of repayment to the Agent (before and after judgment). Interest (a) if paid by such Lender (i) for each day from and including the date of the Agent’s payment to and including the second
Business Day thereafter, shall accrue at the Federal Funds Rate for such day, and (ii) for each day thereafter, shall accrue at the rate or rates per annum payable under the Notes; and (b) if paid by the Borrowers, shall accrue at the rate
or rates per annum payable under the Notes. All payments to the Agent under this Section shall be made to the Agent at its office set forth in the preamble of this Agreement (or as otherwise directed by the Agent), in dollars, in immediately
available funds, without set-off, withholding, counterclaim or other deduction of any nature. 
 (c) All borrowings under this Agreement
shall be incurred from the Lenders pro rata on the basis of their respective Percentages (except to the extent advanced (i) as a Swing Line Loan, or (ii) by the Agent on behalf of any Lender as provided in subsection (a) or
(b) above). It is understood that no Lender shall be responsible for any other Lender’s failure to meet its obligation to make advances hereunder, and that each Lender shall be obligated to make advances required to be made by it hereunder
regardless of the failure of any other Lender to make its advances hereunder. 
 (d) Each payment and prepayment received by the Agent for
the account of the Lenders shall be distributed first to the Swing Line Lender for application to any Swing Line Outstandings, and then to each Lender entitled to share in such payment, ratably in accordance with each Lender’s Percentage.
Notwithstanding the provisions of Section 9.2(e) of this Agreement, any Lender who has failed to fund its Percentage of any advance under the Loan shall not be entitled to share in any such payment(s) until such time as the funding deficiency
caused thereby, together with interest thereon (as provided in subsection (b) above), has been paid to the Agent in accordance with the terms and conditions of this Agreement. Payments from the Agent to the Lenders shall be made by wire
transfer in accordance with written instructions provided to the Agent by the Lenders from time to time. Unless the Agent shall have received notice from the Borrowers prior to the date on which any payment is due to the Lenders hereunder that the
Borrowers will not make such payment in full, the Agent may assume that the Borrowers have made such payment in full on such date and the Agent, in reliance upon such assumption, may cause to be distributed to each Lender on such due date an amount
equal to the amount then due such Lender. If and to the extent the Borrowers shall not have made such payment in full to the Agent, each Lender shall repay to the Agent upon its demand therefor such amount distributed to such Lender, together with
interest thereon at the overnight Federal Funds Rate for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent. 
  

 50 

 (e) If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any
right of setoff, or otherwise) in excess of such Lender’s Percentage of payments, such Lender shall forthwith purchase from the other Lender(s) such participations in the Loans made by them as shall be necessary to cause such purchasing Lender
to share the excess payment ratably with each of the other Lender(s); provided, however, if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from the other Lender(s) shall be rescinded and
each other Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (1) the amount of such Lender’s
required repayment, to (2) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount recovered. Each Borrower agrees that any Lender
purchasing a participation from another Lender pursuant to this Section 10.13(e), to the fullest extent permitted by law, may exercise all of its rights of payment with respect to such participation as fully as if such Lender were the direct
creditor of the Borrowers in the amount of such participation. 
 10.14 Benefit of Article. The provisions of this Article 10
are solely for the benefit of the Agent and Lenders. Except as otherwise expressly set forth in this Article 10, no Borrower shall have any rights under any of the provisions of this Article 10; it being understood that the provisions of this
Article 10 are not in limitation of any right, remedy, power, duty, obligation or liability which the Agent would have to or against any Borrower. 
 ARTICLE 11 
 CERTAIN ADDITIONAL RIGHTS AND 
 OBLIGATIONS REGARDING THE COLLATERAL 
 11.1 Power of Attorney. Each Borrower hereby
reaffirms its irrevocable appointment of the Agent, as its agent and attorney-in-fact, with power of substitution, having full power and authority, in its own name, in the name of any Lender(s), in the name of any Borrower or otherwise (but at the
cost and expense of the Borrowers and without notice to any Borrower), to (i) upon an Event of Default, notify Account Debtors obligated on any of the Receivables to make payments thereon directly to the lockbox referenced in Section 11.2
of this Agreement, and to take control of the cash and non-cash proceeds of any such Receivables, which right the Agent may exercise at any time whether or not an Event of Default shall have occurred and be continuing hereunder or was theretofore
making collections thereon; (ii) upon an Event of Default, compromise, extend or renew any of the Collateral constituting Receivables or deal with any of the Collateral as the Agent may deem advisable; (iii) upon an Event of Default,
release its interest in, make exchanges or substitutions for and/or surrender, all or any part of any Borrower’s interest in all or any part of the Collateral; (iv) upon an Event of Default, remove from any Borrower’s place(s) of
business all books, records, ledger sheets, correspondence, invoices and documents relating to or evidencing any of the Collateral, or without cost or expense to the Agent, make such use of any Borrower’s place(s) of business as may be
reasonably necessary to administer, control and/or collect the Collateral; (v) upon an Event of Default, repair, alter or supply goods, if any, necessary to fulfill in whole or in part the purchase order of any Account Debtor; (vi) demand,
collect receipt for and upon an Event of Default, and give renewals, extensions, discharges and releases of all or any part of the Collateral; (vii) upon an Event of Default, institute and prosecute legal and equitable proceedings to enforce
collection of, or realize upon, all or any part of the Collateral; (viii) upon an Event of Default, settle, renew, extend, compromise, compound, exchange or adjust claims with respect to all or any part of the Collateral or any legal
proceedings brought with respect thereto; and (ix) upon an Event of Default, receive and open all mail addressed to any Borrower (other than mail sent to the Lockbox which may be received and opened in the ordinary course of Lockbox procedures
irrespective of whether any Event of Default has occurred), and if an Event of Default exists hereunder, notify the Post Office authorities to change the address for the delivery of mail to any Borrower to such address as the Agent may designate; it
being understood that the rights granted to the Agent in this clause (ix), which are operative on the occurrence of an Event of Default, shall not in any way limit or impair the other rights provided to the Agent and/or Lenders in this Agreement or
any other Loan Document, including, without limitation, their rights with respect to the Collateral Account and the below-referenced lockbox. Furthermore, each Borrower hereby reaffirms its irrevocable appointment of the Agent, as its agent and
attorney-in-fact, with power of substitution, having full power and authority, in its own name, in the name of any Lender(s), in the name of any Borrower or otherwise (but at the cost and expense of the Borrowers and without notice to any Borrower)
and regardless of whether an Event of Default has occurred or any act, event or condition which with notice or the lapse of time, or both, would constitute an Event of Default has occurred, to (a)
  

 51 

 file financing statements and continuation statements covering the Collateral and execute the same on behalf of any
Borrower; (b) charge against any banking account of any Borrower any item of payment credited to any Borrower’s account which is dishonored by the drawee or maker thereof; and/or (iii) endorse the name of any Borrower upon any items
of payment relating to the Collateral or upon any proof of claim in bankruptcy against any Account Debtor. 
 11.2 Lockbox.
Each Borrower hereby authorizes the Agent to receive and collect any amount or amounts due or to become due on account of any Receivables and, at its discretion, to apply the same to the repayment of the Notes, and each Borrower represents,
warrants, acknowledges and agrees that, except where a Permitted Foreign Bank Account is being used, it has established and shall continually maintain on terms and conditions satisfactory to the Agent in all respects, one or more lockboxes (and, if
required by the Agent, one or more blocked accounts) for the collection of Receivables. Except as otherwise may be approved by the Agent in writing, any checks or other remittances received by any Borrower in payment of the Receivables shall be held
in trust by each Borrower for the Agent and Lenders. Caliber shall, within forty-five (45) days after the Restatement Date (or within such longer period as may be reasonably required by Caliber), direct all of its customers (other than
customers making payments to Caliber utilizing a Permitted Foreign Bank Account and certain other customers as may be approved by the Agent) to make payments directly to the lockbox or account described below or any other lockbox or account
designated by the Agent from time to time for the collection of Caliber Receivables, and/or include on all of its invoices, a direction to its customer to make all payments directly to such lockbox or account.

 11.3 Other Agreements. Except as may otherwise be expressly permitted by the terms
of this Agreement, and without limiting any other restrictions or provisions of this Agreement, each Borrower will (i) on demand, subject to any confidentiality and secrecy requirements imposed by any Government agency, make available in form
reasonably acceptable to the Agent, shipping documents and delivery receipts evidencing the shipment of goods which gave rise to the sale or lease of inventory or of an account, contract right or chattel paper, completion certificates or other proof
of the satisfactory performance of services which gave rise to the sale or lease of inventory or of an account, contract right or chattel paper, and each Borrower’s copy of any written contract or order from which a sale or lease of inventory,
an account, contract right or chattel paper arose; and (ii) when requested, advise the Agent when an Account Debtor returns or refuses to retain any goods, the sale or lease of which gave rise to an account, contract right or chattel paper, and
of any delay in delivery or performance, or claims made in regard to any sale or lease of inventory, account, contract right or chattel paper. Upon reasonable notice, all such records will be available for examination by authorized agents of the
Agent. 
 It is expressly understood and agreed, however, that the Agent shall not be required or obligated in any manner to make any
inquiries as to the nature or sufficiency of any payment received by it or to present or file any claims or take any other action to collect or enforce a payment of any amounts which may have been assigned to the Agent or to which the Agent or the
Lenders may be entitled hereunder at any time or times. 
 ARTICLE 12 
 MISCELLANEOUS 
 12.1 Remedies Cumulative. Each right, power and
remedy of the Agent or Lenders provided for in this Agreement or in any other Loan Document or now or hereafter existing at law or in equity, by statute or otherwise, shall be cumulative and concurrent and shall be in addition to every other right,
power or remedy provided for in this Agreement or in any other Loan Document, or now or hereafter existing at law or in equity, by 
  

 52 

 statute or otherwise, and the exercise or beginning of the exercise by the Agent or any Lender of any one or more of such
rights, powers or remedies shall not preclude the simultaneous or later exercise by the Agent or any such Lender of any or all such other rights, powers or remedies. 
 12.2 Waiver. Time is of the essence of this Agreement. No failure or delay by the Agent to insist upon the strict performance of any term, condition, covenant or agreement set forth in this Agreement or
any other Loan Document, or to exercise any right, power or remedy consequent upon a breach thereof, shall constitute a waiver of such term, condition, covenant or agreement or of any such breach, or preclude the Agent or any Lender from exercising
any such right, power or remedy at any later time or times. By accepting payment after the due date of any of the Obligations, neither the Lenders nor the Agent shall be deemed to have waived either the right to require prompt payment when due of
all other Obligations, or the right to declare a default for failure to make payment of any such other Obligations. 
 12.3

 12.4
Entire Agreement. This Agreement and the other Loan Documents constitute the entire agreement of the parties with respect to the Loan and supersede all prior agreements and understandings; it being expressly understood and agreed that
this Agreement is a complete amendment and restatement of the Existing Loan Agreement, the terms and conditions of which have been superseded and replaced in their entirety by the terms and provisions of this Agreement. The parties hereto agree that
this Agreement is given as a continuation, modification and extension of the Existing Loan Agreement and shall not constitute a novation of the Existing Loan Agreement. This Agreement and the other Loan Documents shall continue in full force and
effect for so long as the Borrowers shall be indebted hereunder or under the Notes, and thereafter until the Lenders shall have actually received written notice of the termination hereof from the Borrowers and all Obligations incurred or contracted
before receipt of such notice shall have been fully paid. 
 12.5 Relationship of the Parties. This Agreement provides for the
extension of financial accommodations by each Lender, in its capacity as lender, to the Borrowers, in their capacity as borrowers, and for the payment of interest and repayment of the Obligations by the Borrowers. Certain provisions herein, such as
those relating to compliance with the financial covenants, delivery to the Agent and Lenders of financial statements, and compliance with other affirmative and negative covenants are for the benefit of the Agent and Lenders to protect the
Agent’s and the Lenders’ interests in assuring repayment of the Obligations. Nothing contained in this Agreement shall be construed as permitting or obligating the Lenders or Agent to act as a financial or business advisor or consultant to
any Borrower, as permitting or obligating the Lenders or Agent to control any Borrower or to conduct any Borrower’s operations, as creating any fiduciary obligation on the part of any Lender or the Agent to any Borrower, or as creating any
joint venture, agency or other relationship between the parties other than as explicitly and specifically stated in this Agreement. Each Borrower acknowledges that it has had the opportunity to obtain the advice of experienced counsel of its own
choosing in connection with the negotiation and execution of this Agreement and to obtain the advice of such counsel with respect to all matters contained herein, including, without limitation, the provision in this Agreement for waiver of trial by
jury. Each Borrower further acknowledges that it is experienced with respect to financial and credit matters and has made its own independent decision to request the Obligations and execute and deliver this Agreement. 
  

 54 

 12.6 Waiver of Jury Trial. Each Borrower hereby (a) covenants and agrees not to elect
a trial by jury of any issue triable by a jury, and (b) waives any right to trial by jury fully to the extent that any such right shall now or hereafter exist. This waiver of right to trial by jury is separately given by each Borrower,
knowingly and voluntarily, and this waiver is intended to encompass individually each instance and each issue as to which the right to a jury trial would otherwise accrue. The Agent and the Lenders are hereby authorized and requested to submit this
Agreement to any court having jurisdiction over the subject matter and the parties hereto, so as to serve as conclusive evidence of each Borrower’s herein contained waiver of the right to jury trial. Further, each Borrower hereby certifies that
no representative or agent of the Agent or any Lender (including the Agent’s counsel) has represented, expressly or otherwise, to the undersigned that the Agent or Lenders will not seek to enforce this provision waiving the right to a trial by
jury. 
 12.7 Submission to Jurisdiction; Service of Process; Venue. Any judicial proceeding brought against any Borrower with
respect to this Agreement or any other Loan Document may be brought in any court of competent jurisdiction in the Commonwealth of Virginia, and by execution and delivery of this Agreement, each Borrower accepts for itself and in connection with its
properties, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid court, and irrevocably agrees to be bound by any judgment rendered by such court in connection with this Agreement. Each Borrower irrevocably designates and
appoints the General Counsel of the Primary Operating Company, whose address is c/o ICF Consulting Group, Inc., 9300 Lee Highway, Fairfax, Virginia 22031, as its agent to receive on its behalf service of all process in any such proceeding in any
court in the Commonwealth of Virginia, such service being hereby acknowledged by each Borrower to be effective and binding on it in every respect. A copy of any such process so served shall be mailed by registered or certified mail to the Borrowers
at the address to which notices are to be addressed in accordance with this Agreement, except that any failure to mail such copy shall not affect the validity of service of process. The Borrowers shall at all times maintain an agent for service of
process pursuant to this provision. If any Borrower fails to appoint such an agent, or if such agent refuses to accept service, such Borrower hereby agrees that service upon it by mail shall constitute sufficient notice. Nothing herein shall affect
the right to serve process in any other manner permitted by law or shall limit the right of the Agent or the Lenders to bring proceedings against any Borrower in the courts of any other jurisdiction. 
 12.8 Changes in Capital Requirements. If after the date of this Agreement the Agent shall determine that the adoption of any applicable
law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof, or compliance by the Lenders with any request or directive regarding capital adequacy of any authority, central
bank or comparable agency, which adoption, change or compliance is applicable to all banks generally or to banks similar in size, has or would have the effect of reducing the rate of return on the Lenders’ capital as a consequence of the
Lenders’ obligations hereunder to a level below that which the Lenders could have achieved but for such adoption, change or compliance (taking into consideration the Agent’s policies with respect to capital adequacy), then, after sixty
(60) days prior notice given by the Agent to the Borrowers, the interest rate on the Notes shall be increased to a rate which shall retain the Lenders’ original rate of return on the Lenders’ capital. 
 12.9 [Intentionally Omitted]. 
 12.10 Modification and Waiver. Subject to Section 10.3 hereof, neither this Agreement nor any term, condition, covenant or agreement hereof may be changed, waived, discharged or terminated orally, but that may be
accomplished only by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought. 
 12.11 Transferability. 
 (a) No Borrower shall assign any of its rights, interests or
Obligations under this Agreement or any other Loan Document. 
  

 55 

 (b) No Lender shall assign its interests under this Agreement or any other Loan Document to any person
or entity, without the prior written consent of both Citizens Bank and the Borrowers; provided that (i) the Borrowers’ consent shall not be required for assignments from one Lender to another Lender or at any time during which an Event of
Default shall have occurred and be continuing; and (ii) the Borrowers’ consent shall not be unreasonably withheld or delayed. Subject to obtaining such consent (as required), any Lender may assign its interest, in the ordinary course of
its commercial banking business, at any time, or sell participations in some but not all of its rights and obligations under this Agreement and the other Loan Documents, provided that (a) the purchaser of any such interest is a commercial bank
(a “Participating Lender”) or Eligible Assignee, in either case whose total assets exceed Five Hundred Million and No/100 Dollars ($500,000,000.00); (b) at least thirty (30) days’ prior written notice of such sale or
assignment, which notice must identify the name, address and contact person of the Participating Lender and/or Eligible Assignee, shall have been issued by such transferring Lender to the Agent and the Borrowers; (c) the dollar equivalent of
the Percentage of the transferring Lender being assigned equals or exceeds Five Million and No/100 Dollars ($5,000,000.00); (d) the Agent shall have received a duly executed Assignment and Acceptance Agreement, in the form attached as
Exhibit 8 hereto; and (e) if the proposed assignee of the transferring Lender is not an Affiliate of the transferring Lender, an assignment fee in the amount of Three Thousand Five Hundred and No/100 Dollars ($3,500.00)
shall have been paid to the Agent to reimburse the Agent for costs and expenses incurred in connection with the assignment. 
 12.12
Governing Law; Binding Effect. This Agreement shall be governed by the laws of the Commonwealth of Virginia (without regard to conflict of laws principles) and be binding upon each Borrower and inure to the benefit of the parties
hereto and their respective successors and assigns. 
 12.13 Gender; Number. As used herein, the singular number shall include
the plural, the plural the singular and the use of the masculine, feminine or neuter gender shall include all genders, as the context may require. 
 12.14 Joint and Several Liability. Each Borrower shall be jointly and severally liable for the payment and performance of all obligations and liabilities hereunder. 
 12.15 Materiality. Unless the context clearly indicates to the contrary, determinations regarding the materiality of any act, event,
condition or circumstance shall be in the reasonable judgment of the Agent. 
 12.16 Reliance on the Agent. Each Borrower shall
be entitled to assume that any and all consents, approvals or notices issued or granted by the Agent pursuant to the terms and provisions of this Agreement were, to the extent necessary, authorized by the Required Lenders or all of the Lenders, as
applicable. 
 12.17 The Patriot Act. The Agent and Lenders hereby notify the Borrowers that pursuant to the requirements of
the Patriot Act, they are required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of the Borrowers and other information that will allow the Agent and the Lenders to identify
the Borrowers in accordance with the Patriot Act. 
 12.18 Counterparts. This Agreement may be executed in any number of
counterparts, all of which together shall constitute one and the same document.

 FIRST MODIFICATION TO AMENDED AND RESTATED BUSINESS LOAN AND SECURITY

 AGREEMENT AND OTHER LOAN DOCUMENTS 
 THIS FIRST MODIFICATION TO AMENDED AND RESTATED BUSINESS LOAN AND SECURITY AGREEMENT AND OTHER LOAN DOCUMENTS (this
“Modification”), dated as of March 14, 2006, is made by and among (i) CITIZENS BANK OF PENNSYLVANIA, a Pennsylvania state chartered bank (“Citizens Bank”), acting in its capacity as the agent for the Lenders (the
“Agent”), having offices at 852 1 Leesburg Pike, Suite 405, Vienna, Virginia 22182; (ii) CITIZENS BANK, acting in its capacity as a Lender, and each other “Lender” party to the hereinafter defined Loan Agreement (each, a
“Lender” and collectively, the “Lenders”); and (iii) ICF CONSULTING GROUP, INC., a Delaware corporation (“ICFG”), ICF CONSULTING GROUP HOLDINGS, INC., a Delaware corporation (“ICF Holdings”), and each
other “Borrower” party to the Loan Agreement (together with ICFG and ICF Holdings, each, a “Borrower” and collectively, the “Borrowers”), each having offices at 9300 Lee Highway, Fairfax, Virginia 22031. Capitalized
terms used but not defined herein shall have the meanings attributed to such terms in the Loan Agreement. 
 WHEREAS, pursuant to the
terms of a certain Amended and Restated Business Loan and Security Agreement dated as of October 5, 2005 (as amended, modified or restated from time to time, the “Loan Agreement”), by and among the Borrowers, the Agent and the
Lenders, the Borrowers obtained loans and certain other financial accommodations (collectively, the “Loan”) from the Lenders in the aggregate maximum principal amount of Seventy-five Million and No/100 Dollars ($75,000,000.00); and

 WHEREAS, the Loan is evidenced by the Notes and secured by, among other things, the collateral described in the Loan Agreement; and

 WHEREAS, the Borrowers anticipate a temporary need for additional capital and have requested that, for a limited period of time,
the Agent and Lenders make overadvances available to the Borrower; and 
 WHEREAS, the Agent and Lenders have agreed to grant the
Borrowers’ request, subject to the terms and conditions set forth herein; and 
 WHEREAS, the Borrowers, the Agent and the
Lenders have also agreed to (i) revise the Leverage Ratio covenant of the Borrowers set forth in Section 6.15(b) of the Loan Agreement, (ii) revise the Maximum Total Senior Debt Covenant of the Borrowers set forth in
Section 6.15(e) of the Loan Agreement, and (iii) modify the pricing for (i.e., the interest rate charged on) amounts advanced under Facility A set forth on Exhibit 7 attached to the Loan Agreement; and 
 WHEREAS, the Borrowers, the Agent and the Lenders desire to enter into this Modification to memorialize the agreements and understanding of the
parties with respect to the foregoing matters, as hereinafter provided. 
 NOW THEREFORE, for Ten Dollars ($10.00) and other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1.
Recitals. The foregoing recitals are hereby incorporated herein by this reference and made a part hereof, with the same force and effect as if fully set forth herein. 
 2. Temporary Allowance for Overadvances. Notwithstanding anything to the contrary set forth in Section 1.3 of the Loan Agreement, so long as
no Event of Default shall have occurred and be continuing, and no act, event or condition shall have occurred and be continuing which with notice or the lapse of time, or both shall constitute an Event of Default, and subject to satisfaction of all
other 

 terms and conditions for advances set forth in the Loan Agreement, the Borrowers may obtain over-advances of the proceeds
of Facility A as follows: (i) from the date hereof through and including June 30, 2006, up to the lesser of (a) the Facility A Commitment Amount and (b) the Maximum Borrowing Base plus Six Million and No/100 Dollars
($6,000,000.00); and (ii) from July 1, 2006 through and including August 31, 2006, up to the lesser of (a) the Facility A Commitment Amount and (b) the Maximum Borrowing Base plus Four Million and No/100 Dollars
($4,000,000.00). No over-advance shall be permitted after August 31, 2006, and any and all over-advances in excess of the limits set forth in this paragraph (including, without limitation, any over-advance existing or arising after
August 31, 2006) shall constitute a Borrowing Base Deficiency, and the Borrowers shall immediately make a principal payment in the amount of such Borrowing Base Deficiency. 
 3. Financial Covenant Amendments. 
 (a) Maximum Leverage Ratio. Notwithstanding anything to the contrary set forth in Section 6.15(b) of the Loan Agreement, the Borrowers will maintain a Leverage Ratio of not more than 4.00 to 1.00 for the Fiscal Quarters ending
March 31, 2006 and June 30, 2006 (in lieu of the requirement for a Leverage Ratio of not more than 3.50 to 1.00 for such periods, as set forth in Section 6.15(b) of the Loan Agreement). For all applicable measurement periods
thereafter, the Borrowers will maintain the Leverage Ratio set forth in Section 6.15(b) of the Loan Agreement (i.e., not more than 3.50 to 1.00). 
 (b) Maximum Total Senior Debt Covenant. Notwithstanding anything to the contrary set forth in Section 6.15(e) of the Loan Agreement, the Borrowers will not suffer or permit Total Senior Debt to exceed an
amount equal to one hundred fifteen percent (115%) of the aggregate amount of all of the Borrowers’ Receivables (including all billed and unbilled Receivables) for the Fiscal Quarter ending March 31, 2006 (in lieu of the requirement
for Total Senior Debt to be less than an amount equal to 100% of the aggregate amount of all of the Borrowers’ Receivables (including all billed and unbilled Receivables)). For all measurement periods thereafter, the Borrowers will not suffer
or permit Total Senior Debt to exceed an amount equal to 100% of the aggregate amount of all of the Borrowers’ Receivables (including all billed and unbilled Receivables). 
 4. Modification to Covenant Compliance Certificate and Pricing Grid. Exhibit 5 and Exhibit 7 attached to
the Loan Agreement are hereby deleted in their entirety, and Exhibit 5 and Exhibit 7 attached to this Modification substituted in lieu thereof. 
 5. Interest Rate. From and after the date of this Modification (and until the interest rate charged on amounts outstanding under the Notes would
change pursuant to the Notes on or after June 1, 2006), the interest rates for amounts outstanding under the Notes will be fixed at Level IV set forth on the Pricing Grid (attached as Exhibit 7 hereto). 
 6. Miscellaneous. 
 (a) Simultaneously
with the execution and delivery of this Modification (and as a condition precedent to its effectiveness), the Borrowers shall pay to the Agent, in immediately available funds: (i) a commitment/waiver fee, in the amount of One Hundred Thousand
and No/100 Dollars ($100,000.00), for the ratable benefit of the Lenders; and (ii) all of the Agent’s reasonable costs and expenses associated with this Modification and the transactions referenced herein or contemplated hereby, including,
without limitation, the Agent’s reasonable legal fees and expenses. 
 (b) Each Borrower hereby represents, warrants, acknowledges and
agrees that as of the date hereof (a) there are no set-offs or defenses against and no defaults under any of the Notes, the Loan Agreement or any other Loan Document; (b) no act, event or condition has occurred which, with notice or the
passage of time, or both, would constitute a default under any of the Notes, the Loan 

 Agreement or any other Loan Document; (c) all of the representations and warranties of the Borrowers contained in
the Loan Agreement are true and correct as of the date hereof (except to the extent that such representations and warranties expressly relate solely to an earlier date), unless the Borrowers are unable to remake and redate any such representation or
warranty, in which case the Borrowers have previously disclosed the same to the Agent and the Lenders in writing, and such inability does not constitute or give rise to an Event of Default; and (d) all schedules attached to the Loan Agreement
with respect to any particular representation and warranty of the Borrowers set forth in the Loan Agreement (as modified) remain true, accurate and complete, as updated in writing to the Agent as of the date of this Modification. 
 (c) The Borrowers, and their respective representatives, successors and assigns, hereby jointly and severally, knowingly and voluntarily RELEASE,
DISCHARGE, and FOREVER WAIVE and RELINQUISH any and all claims, demands, obligations, liabilities, defenses, affirmative defenses, setoffs, counterclaims, actions, and causes of action of whatsoever kind or nature, whether known or unknown, which
they have, may have, or might have or may assert now or in the future against the Agent and/or the Lenders directly or indirectly, arising out of, based upon, or in any manner connected with any transaction, event, circumstance, action, failure to
act, or occurrence of any sort or type, in each case related to, arising from or in connection with the Loan, whether known or unknown, and which occurred, existed, was taken, permitted, or begun prior to the date hereof (including, without
limitation, any claim, demand, obligation, liability, defense, counterclaim, action or cause of action relating to or arising from the grant by the Borrowers to the Agent and/or the Lenders of a security interest in or encumbrance on collateral that
is, was or may be subject to, or an agreement by which the Borrowers are bound and which contains, a prohibition on further mortgaging or encumbering the same). The Borrowers hereby acknowledge and agree that the execution of this Modification by
the Agent and the Lenders shall not constitute an acknowledgment of or an admission by the Agent and/or the Lenders of the existence of any such claims or of liability for any matter or precedent upon which any liability may be asserted. 

(d) Except as expressly set forth herein, nothing contained in this Modification is intended to or shall otherwise act to nullify, discharge, or
release any obligation incurred in connection with the Notes, the Loan Agreement and/or the other Loan Documents or to waive or release any collateral given by any Borrower to secure the Notes, nor shall this Modification be deemed or considered to
operate as a novation of the Notes, the Loan Agreement or the other Loan Documents. Except to the extent of any express conflict with this Modification or except as otherwise expressly contemplated by this Modification, all of the terms and
conditions of the Notes, the Loan Agreement and the other Loan Documents shall remain in full force and effect, and the same are hereby expressly approved, ratified and confirmed. In the event of any express conflict between the terms and conditions
of the Notes, the Loan Agreement or the other Loan Documents and this Modification, this Modification shall be controlling and the terms and conditions of such other documents shall be deemed to be amended to conform with this Modification.

 (e) If any term, condition, or any part thereof, of this Modification, the Loan Agreement or of the other Loan Documents shall for any
reason be found or held to be invalid or unenforceable by any court or governmental agency of competent jurisdiction, such invalidity or unenforceability shall not affect the remainder of such term, provision or condition nor any other term,
provision, or condition of this Modification, the Loan Agreement and the other Loan Documents, and this Modification, the Loan Agreement and the other Loan Documents shall survive and be construed as if such invalid or unenforceable term, provision
or condition had not been contained therein. 
 (f) Each Borrower acknowledges that, at all times prior to and through the date hereof, the
Agent and the Lenders have acted in good faith and have conducted themselves in a commercially reasonable manner in their relationship with such Borrower in connection with this Modification and in connection with the obligations of the Borrowers to
the Agent and the Lenders under the Loan; the Borrowers hereby waiving and releasing any claims to the contrary. 

 (g) Each Borrower, Lender and the Agent hereby acknowledges and agrees that, from and after the date
hereof, all references to the “Loan Agreement” set forth in any Loan Document shall mean the Loan Agreement, as modified pursuant to this Modification and any other modification of the Loan Agreement dated prior to the date hereof.

 (h) Each Borrower hereby represents and warrants that, as of the date hereof, such Borrower is indebted to the Lenders in respect of the
amounts due and owing under the Notes, all such amounts remain outstanding and unpaid and all such amounts are payable in full, without offset, defenses, deduction or counterclaim of any kind or character whatsoever. 
 (i) Each Borrower acknowledges (a) that it has participated in the negotiation of this Modification, and no provision of this Modification shall be
construed against or interpreted to the disadvantage of any party hereto by any court or other governmental or judicial authority by reason of such party having or being deemed to have structured, dictated or drafted such provision; (b) that it
has had access to an attorney of its choosing in the negotiation of the terms of and in the preparation and execution of this Modification, and it has had the opportunity to review, analyze, and discuss with its counsel this Modification, and the
underlying factual matters relevant to this Modification, for a sufficient period of time prior to the execution and delivery hereof; (c) that all of the terms of this Modification were negotiated at arm’s length; (d) that this
Modification was prepared and executed without fraud, duress, undue influence, or coercion of any kind exerted by any of the parties upon the others; and (e) that the execution and delivery of this Modification is the free and voluntary act of
such Borrower. 
 (j) This Modification shall be governed by the laws of the Commonwealth of Virginia and shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns. 
 (k) This Modification may be executed in any number of
counterparts, each of which shall be deemed an original and all of which together shall be deemed one and the same instrument. Signature pages may be exchanged by facsimile and each party hereto agrees to be bound by its facsimile signature.

 THIS SECOND MODIFICATION TO AMENDED AND RESTATED BUSINESS LOAN AND SECURITY AGREEMENT AND OTHER LOAN DOCUMENTS (this “Modification”), dated as of August 25, 2006, is made by and among

party to the Loan Agreement (together with ICFG and ICF International, each, a “Borrower” and collectively, the “Borrowers”), each having offices at 9300 Lee Highway, Fairfax, Virginia 22031. Capitalized terms used
but not defined herein shall have the meanings attributed to such terms in the Loan Agreement. 
 W I T N
E S S E T H    T H A T: 
 WHEREAS, pursuant to the terms of a certain Amended and Restated Business Loan and Security Agreement dated as of October 5, 2005 (as amended, modified or restated from time to time, the “Loan
Agreement”), by and among the Borrowers, the Agent and the Lenders, the Borrowers obtained loans and certain other financial accommodations (collectively, the “Loan”) from the Lenders in the aggregate maximum principal
amount of Seventy-five Million and No/100 Dollars ($75,000,000.00); and 
 WHEREAS, pursuant to the terms of a First
Modification to Amended and Restated Business Loan and Security Agreement and Other Loan Documents dated as of March 14, 2006, the Lenders agreed to a temporary allowance of up to Six Million and No/100 Dollars ($6,000,000.00) for over-advances
for the benefit of the Borrowers (the “Over-Advance Allowance”); and 
 WHEREAS, the Loan is evidenced by the
Notes and secured by, among other things, the collateral described in the Loan Agreement; and 
 WHEREAS, ICF International,
Inc. intends to file an initial public offering (the “IPO”) of its common stock, a portion of the proceeds of which will be used by the Borrowers to reduce, respectively, the outstanding principal balance of Facility B, Facility C
and Swing Line Outstandings, and ultimately, if proceeds still remain available, Facility A, and in connection therewith, the Borrowers have requested that the Agent and the Lenders approve the transactions contemplated by the IPO and modify several
provisions of the Loan Agreement in connection therewith; and 
 WHEREAS, the Agent and Lenders have agreed to grant the
Borrowers’ request, subject to the terms and conditions set forth herein; and 
 WHEREAS, the Borrowers, the Agent and the
Lenders have also agreed to, among other things: (i) increase the commitment amount for the Revolving Facility; (ii) revise the Fixed Charge Coverage Ratio and Leverage Ratio covenants of the Borrowers set forth in Sections 6.15(a) and
6.15(b) of the Loan Agreement; (iii) increase the Over-Advance Allowance to Ten Million and No/100 Dollars ($10,000,000.00); (iv) waive the requirement that the Borrowers maintain and keep in full force and effect a key man life insurance
policy on the life of Don Zimmerman; and (v) modify the pricing for (i.e., the 

 
interest rate charged on) amounts advanced under Facility A, Facility B and Facility C set forth on Exhibit 7 attached to the Loan Agreement; and 

WHEREAS, the Borrowers, the Agent and the Lenders desire to enter into this Modification to memorialize the agreements and understanding
of the parties with respect to the foregoing matters, as hereinafter provided. 
 NOW THEREFORE, for Ten Dollars
($10.00) and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Recitals. The foregoing recitals are hereby incorporated herein by this reference and made a part hereof, with the same force and effect as if fully set forth herein. 
 2. Approval of the IPO. Subject to the terms and conditions of this Modification and the other Loan Documents, the Agent and the Lenders hereby
consent, for all purposes for which such consent may be necessary or required, to the Borrowers consummation of the transactions contemplated by the IPO. It is understood, agreed and acknowledged that immediately upon consummation of the
transactions contemplated by the IPO, the Borrowers shall pay to the Agent, for the ratable benefit of the Lenders a portion of the proceeds of the IPO to which the Borrowers are entitled, net of: (i) the underwriting commission incurred by the
Borrowers in connection with the IPO; (ii) normal and customary underwriting and offering costs and expenses incurred by the Borrowers in connection with the IPO; and (iii) payments to fund the exit pool bonus, in an amount not to exceed
$3,000,000.00, such proceeds to be used to reduce, respectively, the outstanding principal balance of Facility B, Facility C and Swing Line Outstandings, and ultimately, if proceeds still remain, Facility A; it being understood and agreed that any
such reduction to the amounts outstanding under Facility A from IPO proceeds will not cause a permanent reduction of the Facility A Commitment Amount (notwithstanding anything to the contrary set forth in the Loan Agreement). 
 3. Certain Waivers. With respect to the transactions contemplated by the IPO, the Agent and the Lenders hereby waive the prohibitions set forth in
the following sections of the Loan Agreement:

thirty-five percent (35%) of the common stock of ICF International; 
 (ii) Section 7.1(b), relating solely to the
issuance of additional capital stock, and only to the extent necessary to consummate the transactions contemplated by the IPO; 
 (iii) Section 7.8(a), relating to the alteration and amendment of Borrowers’ capital structure; it being understood and agreed that the requirements of each such Section are being waived hereby on a one-time basis only, and solely
to the extent related to and necessary for Borrowers to consummate the transactions contemplated by the IPO; and 
 (iv)
Section 7.13 relating to the First Amendment to Consulting Agreement amending the Consulting Agreement dated June 25, 1999 by and between ICF Consulting Group, Inc. and CMLS Management, L.P.

of this Modification; (d) an opinion of counsel of Squire Sanders & Dempsey L.L.P.; ; (e) pro forma projections, evidencing adequate financial covenant cushions as of the effective date of this Modification; and (f) such
other documents, instruments, certificates of good standing, corporate resolutions, limited liability company consents, UCC financing statements, opinions, certifications, schedules to be attached to the Loan Agreement and agreements as the Agent
may reasonably request, each in such form and content and from such parties as the Agent shall require. 
 5. Definitional Amendments.
The definitions of “EBITDA,” “Facility A”, “Facility A Commitment Amount” and “Key Man Life Insurance Policies” set forth in the section of the Loan Agreement titled “Certain Definitions” are hereby
deleted in their entirety and replaced with the following: 
 “EBITDA” shall mean, with respect to the Borrowers for any
period of determination, net income, plus interest expense, plus federal, state and local income taxes, plus depreciation expense, plus amortization expense, plus all Agent-approved non-cash, non-recurring charges
against income, plus any non-cash charges related to stock and stock-option compensation, plus funds paid from the IPO proceeds for the exit bonus pool (up to $3,000,000) and minus any non-cash gain (to the extent included in
determining net income); and with respect to the determinations of EBITDA for the quarters ending September 30, 2006, December 31, 2006 and March 31, 2007, the consolidated results will be calculated and tested on an annualized
basis, all as determined on a consolidated basis in accordance with GAAP. 
 “Facility A” shall mean the revolving credit
facility being extended pursuant to this Agreement on the basis of Eligible Billed Government Accounts Receivable, Eligible Billed Commercial Accounts Receivable and Eligible Foreign Accounts Receivable, in the maximum principal amount of Sixty-five
Million and No/100 Dollars ($65,000,000.00), with a sub-limit of Five Million and No/100 Dollars ($5,000,000.00) for Letters of Credit. 
 “Facility A Commitment Amount” shall mean Sixty-five Million and No/100 Dollars ($65,000,000.00), or if such amount shall be reduced pursuant to this Agreement, such lesser amount. 
 “Key Man Life Insurance Policies” shall mean each and all of those certain key man life insurance policies covering the
life of Sudakhar Kesavan for the benefit of the Borrowers, in an aggregate minimum amount of Three Million and No/100 Dollars ($3,000,000.00).” 
 6. Temporary Allowance for Over-Advances. Notwithstanding anything to the contrary set forth in Section 1.3 of the Loan Agreement, so long as no Event of Default shall have occurred and be 

  

 3 

 
continuing, and no act, event or condition shall have occurred and be continuing which with notice or the lapse of time, or both shall constitute an Event of
Default, and subject to satisfaction of all other terms and conditions for advances set forth in the Loan Agreement, the Borrowers may obtain over-advances of the proceeds of Facility A as follows: (i) from the date hereof through and including
the earlier of (the “Over-Advance Termination Date”): (A) the consummation of the transactions contemplated by the IPO; and (B) December 15, 2006, up to the lesser of (1) the Facility A Commitment Amount; and
(2) the Maximum Borrowing Base plus Ten Million and No/100 Dollars ($10,000,000.00). No over-advance shall be permitted after the Over-Advance Termination Date, and any and all over-advances in excess of the limits set forth in this
paragraph (including, without limitation, any over-advance existing or arising after the Over-Advance Termination Date) shall constitute a Borrowing Base Deficiency, and the Borrowers shall immediately make a principal payment in the amount of such
Borrowing Base Deficiency. 
 7. Financial Covenant Amendments. Subject to the terms and provisions of this Modification, the
financial covenants set forth in Section 6.15 of the Loan Agreement (and certain definitions relating to the financial covenants contained therein) are hereby amended and restated in their entirety as follows: 
 “6.15 Financial Covenants of the Borrowers. So long as any Obligation remains outstanding or this Agreement remains in effect, the
Borrowers will comply with each of the financial covenants set forth below. 
 (a) Fixed Charge Coverage Ratio. The
Borrowers will maintain on a consolidated basis for each quarter, a Fixed Charge Coverage Ratio of not less than 1.10 to 1.00. For purposes of the foregoing, “Fixed Charge Coverage Ratio” shall mean, for each measurement period, the sum of
the Borrowers’ EBITDA, plus real property rent expense and operating lease expense, minus cash rent paid with respect to the Abandoned Sites net of any rent received from a subtenant with respect to such Abandoned Sites,
divided by the sum of the Borrowers’ real property rent expense and operating lease expense, plus interest expense, plus cash taxes paid, and plus required principal payments on debt and capital lease payments. For
purposes hereof, the “Abandoned Sites” shall mean those leases for space at (i) 33 Hayden Avenue, 3rd
Floor, Lexington, MA 02421; and (ii) 60 Broadway, San Francisco, CA 94111. 
 (b) Leverage Ratio. The Borrowers
will maintain at all times on a consolidated basis a Leverage Ratio of: (i) not more than 4.00 to 1.00 for the Fiscal Quarters ending September 30, 2006 and December 31, 2006; and (ii) not more than 3.50 to 1.00 for each Fiscal
Quarter ending thereafter. For purposes of the foregoing, “Leverage Ratio” shall mean, for each measurement period, the ratio of the Borrower’s Total Debt to EBITDA. The Leverage Ratio shall be measured on the last day of each fiscal
quarter throughout the term of the Loan. 
 (c) Capital Expenditures. The Borrowers shall not, on an aggregate and
consolidated basis, make or incur any capital expenditures, during any Fiscal Year, in excess of an amount equal to one and one-half 

  

 4 

 
percent (1.50%) of the Borrowers’ gross annual revenues for the immediately preceding twelve (12) month period. 
 (d) Continued Profitability. The Borrowers shall not, on a consolidated basis, sustain or incur negative Consolidated Net Operating
Income for any fiscal quarter throughout the term of the Loan. 
 (e) Maximum Total Senior Debt Covenant. The Borrowers
shall not, at any time, suffer or permit Total Senior Debt to exceed the aggregate amount of all of the Borrowers’ Receivables (including all billed and unbilled Receivables). For purposes hereof, “Total Senior Debt” shall mean Total
Debt, less the sum of (i) the aggregate unpaid amount of principal, accrued interest and other amounts payable in respect of Facility C, plus (ii) any and all other indebtedness expressly subordinated to the Loan in payment,
priority, collection and all other respects pursuant to one or more written subordination agreements acceptable to the Agent in all respects. 
 Except as otherwise expressly provided above, the financial covenants referenced above shall be calculated and tested on a rolling four (4) quarter basis, and shall include the results of any entity acquired pursuant to a Permitted
Acquisition and consolidated into the Borrowers’ financial statements within the twelve (12) month period immediately preceding the applicable covenant calculation date; provided, however, that for the quarters ending September 30,
2006, December 31, 2006 and March 31, 2007, the financial covenants referenced above shall be calculated and tested on an annualized basis in accordance with past practice, beginning with the results for the quarter ending
September 30, 2006. Unless otherwise defined, all financial terms used in this Section 6.15 shall have the meanings attributed to such terms in accordance with GAAP.” 
 8. Modification to Lenders’ Commitments, Borrowing Base Certificate, Covenant Compliance Certificate and Pricing Grid. Schedule
1, Exhibit 5 and Exhibit 7 attached to the Loan Agreement are hereby deleted in their entirety, and Schedule 1, Exhibit 5 and
Exhibit 7 attached to this Modification substituted in lieu thereof. A new Exhibit 4A shall be added to the Loan Agreement in the form attached hereto, to be used in lieu of Exhibit
4 from the date of this Modification until the Over-Advance Termination Date. 
 9. Agent’s Exercise of Powers.
Clause (b) of the third sentence of Section 10.3(b) is hereby deleted in its entirety and replaced with the following: “increase the Percentage of the Commitment Amount of any Lender”. 
 10. Agency Provisions. The following is hereby added as Section 10.15 of the Loan Agreement: 
 10.15 Field Audits and Examination Reports; Confidentiality; Disclaimers by Lenders; Other Reports and Information. By becoming a party to this
Agreement, each Lender: 
 (a) is deemed to have requested that the Agent furnish such Lender, promptly after it becomes available, a copy of
each field audit or examination report (each a “Report” and collectively, “Reports”) prepared by or at the request of the Agent, and the Agent shall so furnish each Lender with such Reports; 
  

 5 

 (b) expressly agrees and acknowledges that the Agent does not (i) make any representation or
warranty as to the accuracy of any Report, and (ii) shall not be liable for any information contained in any Report; 
 (c) expressly
agrees and acknowledges that the Reports are not comprehensive audits or examinations, that the Agent or other party performing any audit or examination will inspect only specific information regarding the Borrowers and will rely significantly upon
the Borrowers’ books and records, as well as on representations of the Borrowers’ personnel; 
 (d) agrees to keep all Reports and
other material, non-public information regarding the Borrowers and their operations, assets, and existing and contemplated business plans in a confidential manner; and 
 (e) without limiting the generality of any other indemnification provision contained in this Agreement, agrees: (i) to hold the Agent and any such other Lender preparing a Report harmless from any action the
indemnifying Lender may take or fail to take or any conclusion the indemnifying Lender may reach or draw from any Report in connection with any loans or other credit accommodations that the indemnifying Lender has made or may make to the Borrowers,
or the indemnifying Lender’s participation in, or the indemnifying Lender’s purchase of, a loan or loans of the Borrowers; and (ii) to pay and protect, and indemnify, defend and hold the Agent, and any such other Lender preparing a
Report harmless from and against, the claims, actions, proceedings, damages, costs, expenses, and other amounts (including, attorneys fees and costs) incurred by the Agent and any such other Lender preparing a Report as the direct or indirect result
of any third parties who might obtain all or part of any Report through the indemnifying Lender. 
 In addition to the foregoing: (x) any
Lender may from time to time request of the Agent in writing that the Agent provide to such Lender a copy of any report or document provided by the Borrowers to the Agent that has not been contemporaneously provided by the Borrowers to such Lender,
and, upon receipt of such request, the Agent promptly shall provide a copy of same to such Lender, (y) to the extent that the Agent is entitled, under any provision of the Loan Documents, to request additional reports or information from the
Borrowers, any Lender may, from time to time, reasonably request the Agent to exercise such right as specified in such Lender’s notice to the Agent, whereupon the Agent promptly shall request of the Borrowers the additional reports or
information reasonably specified by such Lender, and, upon receipt 

  

 6 

 
thereof from the Borrowers, the Agent promptly shall provide a copy of same to such Lender, and (z) any time that the Agent renders to the Borrowers a
statement regarding the Collateral Account, the Agent shall send a copy of such statement to each Lender.” 
 11. Notices. The
address for Dickstein Shapiro LLP as set forth in Section 12.3 of the Loan Agreement is hereby amended to read as follows: 
 “Dickstein Shapiro LLP 
 1825 Eye Street, N.W. 
 Washington, DC 20006-5403 
 Attention: Matthew S. Bergman, Esq. 
 Fax: (202) 420-2201” 
 12.
Interest Rate. Subject to the provisos below, upon consummation of the transactions contemplated by the IPO, and prepayment of the Facilities as specified herein with the proceeds thereof, the interest rates for amounts outstanding under the
Notes will be fixed at Level IV set forth on the Pricing Grid (attached as Exhibit 7 hereto) and shall remain at that level until the Leverage Ratio, as calculated quarterly, is determined to have increased to the extent that
the interest rate should reset under the terms of the Pricing Grid (in which event the interest rate shall be increased to the rate specified in the Pricing Grid); provided, however, that so long as there is an Over-Advance Allowance pursuant to the
terms of the Loan Agreement, the interest rates for amounts outstanding under the Notes shall be set at Level I; provided further that upon the earlier of (i) the termination in writing by Borrowers of the Over-Advance Allowance (if such
termination occurs after December 1, 2006); or (ii) the Over-Advance Termination Date, the interest rates for amounts outstanding under the Notes will be immediately set to the level commensurate with the then most recently provided
covenant compliance certificate. 
 13. Miscellaneous. 
 (a) Without limiting the Borrowers’ obligation under Section 1.7(e) of the Loan Agreement to pay the Agent’s costs and
expenses incurred in connection with the Loan (including, without limitation, reasonable attorneys’ fees), simultaneously with the execution and delivery of this Modification (and as a condition precedent to its effectiveness), the Borrowers
shall pay to the Agent, in immediately available funds: (i) a commitment/waiver fee, in the amount of One Hundred Thousand and No/100 Dollars ($100,000.00), paid to the Lenders as follows: (A) Citizens Bank of Pennsylvania-Fifty Thousand
and No/100 Dollars ($50,000.00); (B) PNC Bank, National Association-Twenty Thousand Six Hundred and No/100 Dollars ($20,600.00); (C) Commerce Bank, N.A.-Sixteen Thousand Nine Hundred and No/100 Dollars ($16,900.00); and (D) Chevy
Chase Bank, F.S.B.-Twelve Thousand Five Hundred and No/100 Dollars ($12,500.00); and (ii) all of the Agent’s reasonable costs and expenses associated with this Modification and the transactions referenced herein or contemplated hereby,
including, without limitation, the Agent’s reasonable legal fees and expenses. 
 (b) Each Borrower hereby represents,
warrants, acknowledges and agrees that as of the date hereof (i) there are no set-offs, defenses, deductions or counterclaims against and no defaults under any of the Notes, the Loan Agreement or any other Loan Document; (ii) no act, event
or condition has occurred which, with notice or the passage of time, or both, would constitute a default under any of the Notes, the Loan Agreement or any other Loan Document; (iii) all of the representations and warranties of the Borrowers
contained in the Loan Agreement are true and correct as of the date hereof (except to the extent that such representations and warranties expressly relate solely to an earlier date), 

  

 7 

 
unless the Borrowers are unable to remake and redate any such representation or warranty, in which case the Borrowers have previously disclosed the same to
the Agent and the Lenders in writing, and such inability does not constitute or give rise to an Event of Default; (iv) all schedules attached to the Loan Agreement with respect to any particular representation and warranty of the Borrowers set
forth in the Loan Agreement (as modified) remain true, accurate and complete, as updated in writing to the Agent as of the date of this Modification; (v) all accrued and unpaid interest and fees payable with respect to the Loan have been paid
and (vi) there has been no material adverse change in the business, property or condition (financial or otherwise) of the Borrowers since the date of the most recent financial statements listed on Schedule 5.3 (as updated).

 (c) The Borrowers, and their respective representatives, successors and assigns, hereby jointly and severally, knowingly
and voluntarily RELEASE, DISCHARGE, and FOREVER WAIVE and RELINQUISH any and all claims, demands, obligations, liabilities, defenses, affirmative defenses, setoffs, counterclaims, actions, and causes of action of whatsoever kind or nature, whether
known or unknown, which they have, may have, or might have or may assert now or in the future against the Agent and/or the Lenders directly or indirectly, arising out of, based upon, or in any manner connected with any transaction, event,
circumstance, action, failure to act, or occurrence of any sort or type, in each case related to, arising from or in connection with the Loan, whether known or unknown, and which occurred, existed, was taken, permitted, or begun prior to the date
hereof (including, without limitation, any claim, demand, obligation, liability, defense, counterclaim, action or cause of action relating to or arising from the grant by the Borrowers to the Agent and/or the Lenders of a security interest in or
encumbrance on collateral that is, was or may be subject to, or an agreement by which the Borrowers are bound and which contains, a prohibition on further mortgaging or encumbering the same). The Borrowers hereby acknowledge and agree that the
execution of this Modification by the Agent and the Lenders shall not constitute an acknowledgment of or an admission by the Agent and/or the Lenders of the existence of any such claims or of liability for any matter or precedent upon which any
liability may be asserted. 
 (d) Except as expressly set forth herein, nothing contained in this Modification is intended to
or shall otherwise act to nullify, discharge, or release any obligation incurred in connection with the Notes, the Loan Agreement and/or the other Loan Documents or to waive or release any collateral given by any Borrower to secure the Notes, nor
shall this Modification be deemed or considered to operate as a novation of the Notes, the Loan Agreement or the other Loan Documents. Except to the extent of any express conflict with this Modification or except as otherwise expressly contemplated
by this Modification, all of the terms and conditions of the Notes, the Loan Agreement and the other Loan Documents shall remain in full force and effect, and the same are hereby expressly approved, ratified and confirmed. In the event of any
express conflict between the terms and conditions of the Notes, the Loan Agreement or the other Loan Documents and this Modification, this Modification shall be controlling and the terms and conditions of such other documents shall be deemed to be
amended to conform with this Modification. 
 (e) If any term, condition, or any part thereof, of this Modification, the Loan
Agreement or of the other Loan Documents shall for any reason be found or held to be invalid or unenforceable by any court or governmental agency of competent jurisdiction, such invalidity or unenforceability shall not affect the remainder of such
term, provision or condition nor any other term, provision, or condition of this Modification, the Loan Agreement and the other Loan Documents, and this Modification, the Loan Agreement and the other Loan Documents shall survive and be construed as
if such invalid or unenforceable term, provision or condition had not been contained therein. 
  

 8 

 (f) Each Borrower acknowledges that, at all times prior to and through the date hereof,
the Agent and the Lenders have acted in good faith and have conducted themselves in a commercially reasonable manner in their relationship with such Borrower in connection with this Modification and in connection with the obligations of the
Borrowers to the Agent and the Lenders under the Loan; the Borrowers hereby waiving and releasing any claims to the contrary. 
 (g) Each Borrower, Lender and the Agent hereby acknowledges and agrees that, from and after the date hereof, all references to the “Loan Agreement” set forth in any Loan Document shall mean the Loan Agreement, as modified pursuant
to this Modification and any other modification of the Loan Agreement dated prior to the date hereof. 
 (h) Each Borrower
hereby represents and warrants that, as of the date hereof, such Borrower is indebted to the Lenders in respect of the amounts due and owing under the Notes, all such amounts remain outstanding and unpaid and all such amounts are payable in full,
without offset, defenses, deduction or counterclaim of any kind or character whatsoever. 
 (i) Each Borrower acknowledges
(a) that it has participated in the negotiation of this Modification, and no provision of this Modification shall be construed against or interpreted to the disadvantage of any party hereto by any court or other governmental or judicial
authority by reason of such party having or being deemed to have structured, dictated or drafted such provision; (b) that it has had access to an attorney of its choosing in the negotiation of the terms of and in the preparation and execution
of this Modification, and it has had the opportunity to review, analyze, and discuss with its counsel this Modification, and the underlying factual matters relevant to this Modification, for a sufficient period of time prior to the execution and
delivery hereof; (c) that all of the terms of this Modification were negotiated at arm’s length; (d) that this Modification was prepared and executed without fraud, duress, undue influence, or coercion of any kind exerted by any of
the parties upon the others; and (e) that the execution and delivery of this Modification is the free and voluntary act of such Borrower. 
 (j) This Modification shall be governed by the laws of the Commonwealth of Virginia (without regard to conflict of laws provisions) and shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns. 
 (k) This Modification may be executed in any number of counterparts, each of which shall
be deemed an original and all of which together shall be deemed one and the same instrument. Signature pages may be exchanged by facsimile and each party hereto agrees to be bound by its facsimile signature.

 WHEREAS, the Company has registered shares of its common stock for sale to the public (the “Offering”);

 NOW, THEREFORE, in consideration of the mutual covenants and promises contained herein, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 
  

	1.	Term of Employment. 

 The Company hereby employs
the Executive, and the Executive hereby accepts employment with the Company, upon the terms and conditions set forth in this Agreement. Subject to the provisions of Section 5, this Agreement may be terminated by either party upon forty-five
(45) days notice. 
  

	2.	Title; Duties. 

  

	 	(a)	 President and Chief Executive Officer and Chairman of the Board of Directors. The Executive shall be employed as President and Chief Executive Officer and
shall serve as Chairman of the Board of Directors of the Company. The Executive shall perform such services consistent with his position as may be assigned to him from time to time by the Board of Directors of the Company and 

	 	 
are consistent with the applicable law and the Certificate of Incorporation and Bylaws of the Company, including, but not limited to, managing the business
and affairs of the Company. 

  

	 	(b)	Committees. At all times during the Executive’s employment, the Executive shall be a member of the Company’s Executive Committee if there shall be such a Committee

	 	(c)	Employment of Company Officers. No offers of employment by the Company to senior executive officers shall be made without the prior approval of the Executive.

  

	3.	Extent of Services. 

  

	 	(a)	General. The Executive agrees not to engage in any business activities during the Executive’s employment except those which are for the sole benefit of the Company, and
to devote his entire business time, attention, skill and effort to the performance of his duties under this Agreement. Notwithstanding the foregoing, the Executive may (i) engage in personal investments, provided that the Executive shall
not acquire more than 5% of the equity of another business without the prior approval of the Compensation Committee of the Board of Directors, (ii) engage in charitable, professional and civic activities (including serving on the board of
directors of non-profit, charitable and civic organizations) which do not impair the performance of his duties to the Company, and (iii) with the prior approval of the Compensation Committee, serve on the boards of directors or trustees of
for-profit corporations other than the Company. The Executive shall, to the best of his ability, execute the strategic plan of the Company as approved by the Board, perform his duties, adhere to the Company’s published policies and procedures,
promote the Company’s interests, reputation, business and welfare, and work actively with the Board of Directors and other senior managers to help augment the existing business base, increase the corporate contract backlog and identify and
develop new business opportunities. 

  

	 	(b)	Corporate Opportunities. The Executive agrees that, unless approved by the Board of Directors, he will not take personal advantage of any business opportunities which arise

	4.	Compensation and Benefits

2007, the annual rate of Base Salary shall be increased by no less than $25,000 over the annual rate of Base Salary in effect for the preceding year. Effective January 1, 2008, and on each subsequent January 1 during the Executive’s
employment, the annual rate of Base Salary shall be increased by no less than the increase in the CPI National Index for the year over the annual rate of Base Salary in effect for the preceding year. In addition to the aforementioned increases in
Base Salary, the 

  

 - 2 - 

	 	 
Compensation Committee may, from time to time, increase the Executive’s Base Salary based on the performance of the Company and other factors deemed
relevant by the Compensation Committee. Effective as of the date of any such increase, the Base Salary as so increased shall be considered the new Base Salary for all purposes of this Agreement and thereafter may not be reduced. The salary shall be
payable in arrears in approximately equal bi-weekly installments on the Company’s regularly scheduled payroll dates, minus such deductions as may be required by law or reasonably requested by the Executive. 

  

	 	(b)	Incentive Compensation. In the discretion of the Compensation Committee of the Board of Directors, the Executive shall be eligible for annual incentive compensation
(“IC”) awards for the immediately preceding fiscal year in an amount up to 100% of the Executive’s Base Salary for the prior fiscal year. 

  

	 	(c)	Equity Awards. In the discretion of the Compensation Committee of the Board of Directors, the Executive shall be eligible to receive stock options, restricted shares and
other equity awards on such terms as may be determined by the Compensation Committee. 

  

	 	(d)	Deductions from Compensation. The Company shall withhold from the Executive’s compensation any and all applicable local, state, federal, or foreign taxes, including, but
not limited to, income tax, withholding tax, social security tax, and pension contributions, if any. 

  

	 	(e)	Employee Benefits. The Executive shall be entitled to participate in any and all employee benefit programs for which the Executive may be eligible, as may exist at any
particular time and from time to time during the Executive’s employment. 

  

	 	(f)	Executive Benefits. The Executive shall be entitled to all executive benefits that the Company makes available to other executives, as may exist at any particular time and
from time to time during the Executive’s employment. In addition, the Company shall maintain and pay all premiums for a life insurance policy on the Executive in an amount of at least $1,000,000, the beneficiaries of which policy shall be the
Executive’s immediate family, provided that the Executive is eligible for such a life insurance policy at reasonable rates. The Company also shall pay expenses up to $3,000 per year relating to the Executive’s tax and estate
planning. Further, the Executive may attend, at the Company’s expense, subject to prior approval of expenses by the Compensation Committee, two weeks of management education during each year of the Executive’s employment.

  

	 	(g)	Reimbursement of Business Expenses. The Company shall reimburse the Executive for all reasonable travel, entertainment and other expenses incurred or paid by the Executive in
connection with, or related to, the performance of his duties, responsibilities or services under this Agreement, upon presentation by the Executive of documentation, expense statements, vouchers, and/or such other supporting information as the
Company may reasonably request. 

  

	5.	Termination 

  

	 	(a)	 Termination by the Company for Cause. The Company may terminate the Executive’s employment at any time for Cause upon written notice by the 

  

 - 3 - 

	 	 
Company to the Executive. “Cause” for termination shall mean any of the following: (i) any act that would constitute a material
violation of the Company’s material written policies; (ii) willfully engaging in conduct materially and demonstrably injurious to the Company, provided, however, that no act or failure to act, on the Executive’s part,
shall be considered “willful” unless done, or omitted to be done, by the Executive not in good faith and without reasonable belief that his action or omission was in the best interest of the Company; (iii) being indicted for, or if
charged with but not indicted for, being tried for (a) a crime of embezzlement or a crime involving moral turpitude or (b) a crime with respect to the Company involving a breach of trust or dishonesty or (c) in either case, a plea of
guilty or no contest to such a crime; or (iv) abuse of alcohol in the workplace, use of any illegal drug in the workplace or a presence under the influence of alcohol or illegal drugs in the workplace. 

  

	 	(b)	Termination by the Executive. The Executive may voluntarily terminate his employment upon forty-five (45) days prior written notice to the Company. As provided in the
Original Agreement, because the Executive has served continuously since 1999, the Executive may, in his discretion, declare that such termination is for “Good Reason” and be entitled to the benefits of Section 6(c) hereof.

  

	 	(c)	Termination by the Company Without Cause. Termination of the Executive’s employment without Cause shall mean termination by the Company (i) for any reason other
than for Cause, (ii) upon the death of the Executive, or (iii) in the Company’s sole discretion, upon thirty (30) days prior written notice in the event the Executive becomes “Disabled,” as defined in any group
long-term disability insurance contract maintained by the Company under which the Executive is covered, or, if the Company shall not maintain such insurance, “Disabled” shall mean that the Executive is incapacitated by reason of a
physical or mental illness which is long-term in nature and which prevents the Executive from performing the substantial and material duties of his employment with the Company, provided that such incapacity can reasonably be expected to
prevent the Executive from working at least six consecutive months in any twelve month period. The Company may require the Executive to have an examination at any time for the purpose of determining whether the Executive has a long-term disability
described in the preceding sentence, and the Executive agrees to submit to such examination upon request of the Board of Directors; provided that the Company shall pay all costs and expenses associated with such examination.

  

	6.	Effect of Termination 

  

	 	(a)	General. Regardless of the reason for termination of the Executive’s employment, the Executive shall be entitled to the following (provided that the Severance
Protection Agreement shall govern, in accordance with its terms, the benefits, if any, to which the Executive is entitled following any termination of the Executive’s employment following a Change in Control as defined in the Severance
Protection Agreement): 

  

	 	(i)	payment of any unpaid portion of his Base Salary through the effective date of termination; 

  

	 	(ii)	reimbursement for any outstanding reasonable business expense he has incurred in performing his duties hereunder; 

  

 - 4 - 

	 	(iii)	continued insurance benefits to the extent required by law; 

  

	 	(iv)	payment of any accrued but unpaid amounts as required independently of this Agreement by the terms of any bonus or other incentive pay, or any other employee benefit plan or program
of the Company, including but not limited to the Company’s incentive compensation arrangements; and 

  

	 	(v)	vesting of options and other equity awards pursuant to any option, restricted stock or similar equity award agreements through the date of termination. 

  

	 	(b)	Termination by the Company for Cause or by the Executive Without Good Reason. If the Company terminates the Executive’s employment for Cause pursuant to
Section 5(a) or the Executive terminates his employment without Good Reason pursuant to Section 5(b), the Executive shall have no rights or claims against the Company except to receive the payments and benefits described in
Section 6(a). 

  

	 	(c)	Termination by the Company Without Cause or by the Executive for Good Reason. If the Company terminates the Executive’s employment without Cause pursuant to
Section 5(c), or the Executive terminates his employment for Good Reason pursuant to Section 5(b), the Executive shall be entitled to receive, in addition to the items referenced in Section 6(a): 

  

	 	(i)	an amount equal to his monthly Base Salary at the rate in effect on his last day of employment for a period of twenty-four months from the date of termination (such aggregate amount
referred to herein as the “Severance Payment”). Fifty percent (50%) of the Severance Payment shall be paid in a lump-sum amount on the date that is six (6) months after the date of the Executive’s termination, and the
remaining fifty percent (50%) of the Severance Payment shall be paid in approximately equal installments over the following eighteen (18) calendar months, on the Company’s regularly scheduled payroll dates, subject to all legally
required payroll deductions and withholdings for sums owed by the Executive to the Company; and 

  

	 	(ii)	accelerated vesting as of the last day of his employment of all unvested portions of stock options and shares of restricted stock previously issued to the Executive, which options
shall remain exercisable for the remainder of the option term; and 

  

	 	(iii)	a pro-rata share of any IC to which the Executive otherwise would have actually been entitled for the fiscal year in which his employment terminates; such IC (pro-rated on a daily
basis) to be paid to the Executive on the later of (i) the date that is ninety (90) days following the end of the fiscal year in which such termination occurs, or (ii) the date that is six (6) months after the date of such
termination; and 

  

	 	(iv)	at the expense of the Company, and subject to contractual eligibility requirements, continuation of the Executive’s family health and dental insurance policy in effect as of
the date of termination for twenty-four (24) months following termination, or, in the event the Company cannot continue coverage of such policy, the Company shall pay for equivalent coverage for twenty-four (24) months following the
Executive’s termination of employment. 

  

 - 5 - 

	 	(d)	Compliance with Code Section 409A. In the event the Executive’s employment is terminated and, at the time of such termination, (i) the Executive is not a
specified employee within the meaning of Section 409A(a)(2)(B)(i) of the Code, (ii) the amount of the Executive’s Severance Payment does not exceed the amount specified in Proposed Treasury Regulation
Section 1.409A-1(b)(9)(iii)(A) or any successor regulation thereto, or (iii) Section 409A of the Code is otherwise not applicable to the Severance Payment, then, and only in such event: 

  

	 	(i)	The Severance Payment otherwise payable to the Executive pursuant to Section 6(c)(i) of this Agreement shall be paid in the following manner: Fifty percent (50%) of the
Severance Payment shall be paid in a lump-sum amount on the date that is thirty (30) days after the date of the Executive’s termination, and the remaining fifty percent (50%) of the Severance Payment shall be paid in approximately
equal installments over the following twenty-three (23) calendar months, on the Company’s regularly scheduled payroll dates, subject to all legally required payroll deductions and withholdings for sums owed by the Executive to the Company;
and 

  

	 	(ii)	The payment of IC due the Executive pursuant to Section 6(c)(iii) shall be made on the date that is ninety (90) days following the end of the fiscal year in which the
Executive’s termination occurs. 

  

	7.	Confidentiality and Inventions. 

 The Executive
acknowledges that he shall continue to be bound by the ICF Incorporated Employee Agreement on Ideas, Inventions, and Confidential Information executed by the Executive on September 16, 1987, and the ICF Incorporated Employee Confidentiality
Agreement executed by the Executive on July 31, 1986. 
  

	8.	Non-Solicitation. 

  

	 	(a)	Non-Solicitation of Clients. The Executive agrees that, for a period of (i) twenty-four (24) months from the date of termination of the Executive’s employment

Section 5(c), by the Executive for Good Reason pursuant to Section 5(b) or pursuant to the Severance Protection Agreement (the “Client Non-Solicitation Term”), the Executive shall not, directly or indirectly, solicit any
Client of the Company (as defined below) for the purpose of providing services which are competitive with the Company’s major practice areas, as described in the final prospectus relating to the Offering. The Executive further agrees that,
during the Client Non-Solicitation Term, the Executive shall not, directly or indirectly, whether as employee, agent, partner, member, consultant or in any other capacity, participate, assist or be involved, in any respect, in any proposal or
project which the Company is or was involved in during the one (1) year period prior to the date of termination of the Executive’s employment with the Company. 

  

	 	(b)	“Client of the Company” shall mean any person or entity which is or was a client of the Company at any time during the one (1) year period prior to the
termination of the Executive’s employment with the Company or any person or entity which the Company is or was soliciting during the one (1) year period prior to the termination of the Executive’s employment with the Company. If any
such person or entity described above is an agency or department of any federal, state or local government, the “Client of the Company” shall be deemed to be only the specific agency or department with which the Company had or has a client
relationship or to which the Company has made a solicitation and not any other agency or department of such federal, state or local government. 

  

	 	(c)	Non-Solicitation of Employees. The Executive agrees that, for a period of (i) twenty-four (24) months from the date of termination of the Executive’s

to Section 5(c) or by the Executive for Good Reason pursuant to Section 5(b), the Executive shall not hire, solicit or encourage, or cause others to hire, solicit or encourage, any employee of the Company to terminate their employment with
the Company.

Company whose employment with the Company shall have terminated at least six (6) months prior to such efforts by the Executive. 

  

	 	(d)	Acknowledgement. The Executive acknowledges that he will acquire much confidential information concerning the past, present and future business of the Company as the result
of his employment, as well as access to the relationships between the Company and its clients and employees. The Executive further acknowledges that the business of the Company is very competitive and that competition by him in that business during
his employment, or after his employment terminates, would severely injure the Company. The Executive understands and agrees that the restrictions contained in this Section 8 are reasonable and are required for the Company’s legitimate
protection, and do not unduly limit his ability to earn a livelihood. 

  

	9.	Employee Representations and Warranties. The Executive represents and warrants to the Company as follows:

injunctive relief and such other relief as the Company shall elect to enforce the Executive’s covenants in Section 8 of this Agreement.
